FIELD
The present disclosure relates to the technical field of fitness equipment, and more particularly, to a smart wall pulley for fitness.
BACKGROUND
A smart wall pulley for fitness can help people in exercising muscles, body-shaping, and effectively improving physical quality, therefore it is highly popular with the majority of fitness enthusiasts. A common smart wall pulley is composed of two handles and an elastic rope. Since the smart wall pulley for fitness has the characteristics of small floor space and portability, it can help an exerciser to do all-around exercises any time any where, including for example a strength exercise, a flexibility exercise, a pulling exercise, a stretching exercise and the like, and therefore it is an indoor fitness equipment having a very high degree of freedom. However, an existing smart wall pulley for fitness cannot perform data statistics for the exercise process of the exerciser while the exerciser is doing exercises, thus it has a low degree of intelligence. Furthermore, when the length of the elastic rope is adjusted, an adjusting buckle applies a shear force on the elastic rope, which would easily cause the elastic rope to be broken after a long-term use.
SUMMARY
The present disclosure aims to solve at least one of technical problems existing in the prior art.
A smart wall pulley for fitness according to an embodiment of the present disclosure includes an elastic rope, a motion sensing detection device, a fixed pulley assembly, and an adjuster. The elastic rope is elastic. The motion sensing detection device is provided at one end of the elastic rope. A battery, a circuit board and a tension sensor are provided within the motion sensing detection device. The battery and the tension sensor are electrically connected to the circuit board. The adjuster includes a shell and a winding post located within the shell. The other end of the elastic rope passes into the shell, then is wound around the winding post, then passes out from the shell. The other end of the elastic rope is fixedly connected to the shell after being wound around the fixed pulley assembly.
In the smart wall pulley for fitness according to the embodiment of the present disclosure, the winding post is provided within the shell and the elastic rope is wound around the winding post. Therefore, when a user delivers a part of the elastic rope into the shell of the adjuster, the elastic rope may be moved relative to the winding post. Further, Due to the limited space in the shell, another part of the elastic rope will be extruded out of the shell under the drive of the elastic rope, therefore the distance between the adjuster and an end of the elastic rope can be adjusted and thus the length of the smart wall pulley can be adjusted. In addition, when the smart wall pulley is used, both the two parts of the elastic rope may each are subjected to a pulling force, and as the pulling force increases, the elastic rope applies a larger winding force to the winding post, such that the winding post can fix the elastic rope. In addition, by providing the tension sensor at one end of the elastic rope, a pulling force bore by the elastic rope can be detected, therefore a user's training condition can be monitored and recorded, thereby facilitating the user to perform a detailed planning on the training.

DETAILED DESCRIPTION
Embodiments of the present disclosure will be described in detail below, examples of which are shown in the drawings in which the same or similar reference numerals denote same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the figures are exemplary, merely used to explain the present disclosure, and cannot be construed as limiting the present disclosure.
A smart wall pulley 100 for fitness according to embodiments of the present disclosure is described below with reference to FIGS. 1-9.
As shown in FIG. 1, a smart wall pulley 100 for fitness according to an embodiment of the present disclosure includes an elastic rope 110, a motion sensing detection device 10, a fixed pulley assembly 130, and an adjuster 140.
Specifically, the elastic rope 110 is elastic, and the motion sensing detection device 10 is provided at one end of the elastic rope 110. A battery 121, a circuit board 16 and a tension sensor 124 are provided within the motion sensing detection device 10, and the battery 121 and the tension sensor 124 are electrically connected to the circuit board 16. It should be noted that, the tension sensor 124 may be configured to detect a pulling force the elastic rope 110 is bearing, and transmits detected data to an electric component on the circuit board 16. And then, the corresponding electric component converts, through data conversion, information detected by the tension sensor 124 into a form of information that can be read by a user, such that the user can know the pulling force being applied to the smart wall pulley 100. In addition, the tension sensor 124 may be further configured to adjust an overall length of the smart wall pulley 100 in consideration of elastic resistance of the elastic rope 110, such that the smart wall pulley 100 can satisfy needs of different users for different lengths. In addition, it should be noted that the battery 121 may supply power to the tension sensor 124 and electric components on the circuit board 16.
As shown in FIGS. 2-4, the adjuster 140 includes a shell 141 and a winding post 142 located within the shell 141. As shown in FIG. 2 in which a routing path of the elastic rope 110 is indicated by arrows, the other end of the elastic rope 110 passes into the shell 141, then is wound around the winding post 142, then passes out from the shell 141. Finally, the other end of the elastic rope 110 is fixedly connected to the shell 141 after being wound around the fixed pulley assembly 130. It should be noted that, after the other end of the elastic rope 110 comes out of the shell 141, it passes through the fixed pulley assembly 130 and then is connected to the shell 141, thereby achieving automatically adjusting the length of this part of the elastic rope 110, and therefore balancing the length of the elastic rope 110 on both sides of the fixed pulley assembly 130.
It can be understood that, the adjuster 140 can divide the elastic rope 110 into two parts. Here, one part of the elastic rope is from the one end of the elastic rope 110 to the adjuster 140, and is provided with the motion sensing detection device 10 thereon. During a physical training, a user can apply a pulling force to the elastic rope 110 by pulling the motion sensing detection device 10, and at the same time, the motion sensing detection device 10 can detect the magnitude of the pulling force. The other part of the elastic rope is from the other end of the elastic rope 110 to the adjuster 140. On the other part, the elastic rope 110 is wound around the fixed pulley assembly 130, and the user can apply a pulling force to the elastic rope 110 by pulling the fixed pulley assembly 130 during the physical training.
When the smart wall pulley 100 is used, both two parts of the elastic rope 110 may each are subjected to a pulling force. Under the action of the pulling force, the elastic rope 110 is wound around the winding post 142, and as the pulling force increases, the elastic rope 110 applies a larger winding force to the winding post 142, such that a relative position between the elastic rope 110 and the winding post 142 cannot be easily changed and the winding post 142 can play a role of fixing the elastic rope 110. When the smart wall pulley 100 is in a natural state, the elastic rope 110 is not subjected to an external force and can be wound around the winding post 142 in a natural state, and there is no acting force between the elastic rope 110 and the winding post 142. When a user delivers a part of the elastic rope 110 into the shell 141 of the adjuster 140, the elastic rope 110 can be moved relative to the winding post 142. Due to the limited space in the shell 141, another part of the elastic rope 110 will be extruded out of the shell 141 under the driving of the elastic rope 110. Thus, a distance between the adjuster 140 and an end of the elastic rope 110 can be adjusted, thereby the length of the smart wall pulley 100 can be adjusted.
Of course, it can also be understood that, when the smart wall pulley 100 is in a natural state, the user can drive the adjuster 140 to move along the elastic rope 110 by applying a force to the elastic rope 110 on one side of the adjuster 140. At this point, the elastic rope 110 can be moved around the winding post 142, and both a length of the elastic rope 110 located on one side of the adjuster 140 and a length of the elastic rope 110 located on the other side of the adjuster 140 can be changed, that is, the overall length of the smart wall pulley 100 may be adjusted at this time.
In the smart wall pulley 100 for fitness according to the embodiment of the present disclosure, the winding post 142 is provided within the shell 141 and the elastic rope 110 is wound around the winding post 142. Therefore, when the user delivers a part of the elastic rope 110 into the shell 141 of the adjuster 140, the elastic rope 110 may be moved relative to the winding post 142. Further, Due to the limited space in the shell 141, another part of the elastic rope 110 will be extruded out of the shell 141 under the driving of the elastic rope 110, therefore the distance between the adjuster 140 and an end of the elastic rope 110 can be adjusted and thus the length of the smart wall pulley 100 can be adjusted. In addition, when the smart wall pulley 100 is used, both the two parts of the elastic rope 110 may each are subjected to a pulling force, and as the pulling force increases, the elastic rope applies a larger winding force to the winding post, such that the winding post can fix the elastic rope 110. In addition, by providing the tension sensor 124 at one end of the elastic rope 110, a pulling force bore by the elastic rope 110 can be detected, therefore a user's training condition can be monitored and recorded, thereby facilitating the user to perform a detailed planning on the training.
As shown in FIG. 3, the shell 141 may be a double-color injection molded part and includes a soft rubber layer 1416 and a rigid frame 1411 cladded with the soft rubber layer 1416. It should be noted that the double-color injection molding is a way of over-injection molding, and can select injection materials of different colors in the two injection molding processes, thereby facilitating observation of the molding of the structure and improvement of the product quality. The molding process of the double-color injection molding is simple. The rigid frame 1411 can provide a stronger support for the shell 141, thereby improving the overall structural strength of the shell 141. In addition, as shown in FIGS. 2 and 3, the rigid frame 1411 extends toward the inside of the shell 141 to from a reinforcing rib 1412 which defines a channel 1413 for routing lines. A part of the elastic rope 110 located within the shell 141 is located in the channel 1413 for routing lines. On one hand, the channel 1413 for routing lines being defined by a hard structure can effectively defines the path of the elastic rope 110 within the shell 141, thereby facilitating the positioning of the adjuster 140. On the other hand, the reinforcing rib 1412 also has a supporting function, which can effectively increase the overall strength of the shell 141.
According to some embodiments of the present disclosure, as shown in FIGS. 2 and 3, the channel 1413 for routing lines may include a straight segment 1414 and a widened segment 1415. The straight segment 1414 extends along a straight line and communicates with the widened segment 1415. A minimum width of the widened segment 1415 is greater than a maximum width of the straight segment 1414. The winding post 142 is provided in the widened segment 1415. It should be noted that, the straight segment 1414 may define a path of the elastic rope 110 inside the shell 141. In the widened segment 1415, when the elastic rope 110 is wound around the winding post 142, the elastic rope 110 needs to occupy a larger space, and the widened segment 1415 can be configured to accommodate the elastic rope 110 wound around the winding post 142, thereby facilitating adjustment of a relative position between the shell 141 and the elastic rope 110. Further, for convenience of adjustment, the elastic rope 110 may be wound around the winding post 142 in one loop.
As shown in FIGS. 2-4, in some embodiments, in order to facilitate mounting of the elastic rope 110 inside the shell 141, the shell 141 may include an upper shell 143 and a lower shell 144. The upper shell 143 is connected to the lower shell 144 so as to define an installation cavity 1443. One end of the winding post 142 is connected to the lower shell 144. A positioning groove 1431 is provided inside the upper shell 143, and the other end of the winding post 142 is located within the positioning groove 1431. It should be noted that, by providing the positioning groove 1431 and arranging a free end of the winding post 142 within the positioning groove 1431, on the one hand, the winding post 142 may be confined by the positioning groove 1431, and on the other hand, the winding post 142 may be supported by the wall of the positioning groove 1431, so as to prevent the winding post 142 from inclining, bending and the like when bearing a pulling force applied by the elastic rope 110.
In some embodiments, in order to facilitate fixing the upper shell 143 and the lower shell 144 together, as shown in FIG. 4, the lower shell 144 has a screw post 1442 extending towards the upper shell 143. A screw is in a threaded connection with the screw post 1442 after passing through the upper shell 143, such that the upper shell 143 and the lower shell 144 can be assembled together. Thus, the upper shell 143 and the lower shell 144 may be fixed by the screw. For the convenience of fixing the screw, the screw post 1442 may be provided on the lower shell 144, so as to fix the screw by the screw post 1442.
It should be noted that, as long as the upper shell 143 and the lower shell 144 can be fixedly connected together, the fixing manner of the upper shell 143 and the lower shell 144 is not limited the above example. For example, in some examples, as shown in FIGS. 2 and 3, the upper shell 143 has a first snap-fit part 1432, and the lower shell 144 has a second snap-fit part 1441. The first snap-fit part 1432 is in a snap-fit connection with the second snap-fit part 1441. One of the first snap-fit part 1432 and the second snap-fit part 1441 is a slot, and the other is a hook. Further, there may be a plurality of first snap-fit parts 1432 and a plurality of second snap-fit parts 1441. The plurality of first snap-fit parts 1432 are snap fitted to the plurality of second snap-fit parts 1441 in one-to-one correspondence. In the description of the present disclosure, unless otherwise specified, the term “a plurality of” means two or more.
According to some embodiments of the present disclosure, as shown in FIGS. 5-9, the motion sensing detection device 10 may include a connecting shell 125 and a protective shell 11. The connecting shell 125 is connected to the protective shell 11, and is connected to one end of the elastic rope 110. The circuit board 16, the battery 121 and the tension sensor 124 are arranged within the protective shell 11. Thus, interference between components within the connecting shell 125 and the interior of the protective shell 11 is avoided. Further, when components in the protective shell 11 are dismounted and repaired, components in the connecting shell 125 will not be influenced, such that an overall service life of the smart wall pulley 100 can be extended.
As shown in FIG. 9, in some examples, the protective shell 11 has a first cavity 1261 and a second cavity 1262 therein. The battery 121 and the circuit board 16 are located within the first cavity 1261, and the tension sensor 124 is located within the second cavity 1262. A support rib 1263 is provided within the second cavity 1262 and is configured to support the tension sensor 124. Thus, the assembly stability of the tension sensor 124 can be improved, which can improve the detection accuracy of the tension sensor 124.
In order to conveniently connect the protective shell 11 and the connecting shell 125 together, in the example as shown in FIG. 6, an end of the connecting shell 125 facing towards the protective shell 11 has a protrusion 1251, and an end of the protective shell 11 facing towards the connecting shell 125 has a groove 1264. When the connecting shell 125 is buckled with the protective shell 11 by rotation, following rotation of the connecting shell 125, the protrusion 1251 is buckled into the groove 1264 by rotation. It can be understood that, the protrusion 1251 can extend in a direction in which the protective shell 11 rotates and is buckled. When the connecting shell 125 is mounted on the protective shell 11, as the connecting shell 125 rotates relative to the protective shell 11, the protrusion 1251 rotate into the groove 1264. When the protrusion 1251 engages with the groove 1264, the assembly of the connecting shell 125 with the protective shell 11 is completed.
Further, in order to prevent the protrusion 1251 from disengaging from the groove 1264, as shown in FIGS. 7 and 8, the protrusion 1251 has a restricting slot 1252 at a free end thereof, the groove 1264 is provided with a restricting ridge 1265 at an inner wall in the bottom of the groove 1264, and the restricting ridge 1265 can be embedded into the restricting slot 1252. Thus, by snap-fitting the restricting ridge 1265 into the restricting slot 1252, the protrusion 1251 can be stably restricted in the groove 1264, thereby improving the assembly stability of the connecting shell 125 and the protective shell 11, and preventing the connecting shell 125 and the protective shell 11 from being accidentally disengaged from each other.
The adjuster 140 further includes a winder. The elastic rope 110 is wound in the winder. The other end of the elastic rope 110 passes into the shell 141, passes out from the shell 141 after being wound in the winder, then is wound around the fixed pulley assembly 130, and then is fixedly connected to the shell 141.
The winder is adapted to control the elastic rope 110 of the smart wall pulley 100 to be received into the winder or to be released from the winder to adjust a natural length of the smart wall pulley 100. It should be noted that, the winder may receive or release the elastic rope 110, and when it needs to adjust the overall length of the smart wall pulley 100, the elastic rope 110 may be released or received by controlling the winder, so that the overall length of the smart wall pulley 100 may be adjusted. Thus, it can not only simplify the structure of the adjuster 140, but also prevent the elastic rope 110 from wearing under the action of any clamping member, such that the elastic rope 110 can be protected and the service life of the elastic rope 110 can be extended. In addition, the winder may be selected as having a grade adjustment structure. For example, the winder may release or receive the elastic rope 110 according to a predetermined length ratio, that is, when the winder adjusts the length of the elastic rope 110, it releases or receives a same length of the elastic rope 110 per level.
According to some embodiments of the present disclosure, as shown in FIGS. 2 and 3, the channel 1413 for routing lines may include a straight segment 1414 and a widened segment 1415. The straight segment 1414 extends along a straight line, and communicates with the widened segment 1415. A minimum width of the widened segment 1415 is greater than a maximum width of the straight segment 1414. The winder is provided within the widened segment 1415. It should be noted that, the straight segment 1414 may define the path of the elastic rope 110 inside the shell 141, and the widened segment 1415 may accommodate the winder, which can facilitate the arrangement of the winder so as to adjust the relative position between the shell 141 and the elastic rope 110.
To facilitate mounting the elastic rope 110 inside the shell 141, in some embodiments, the shell 141 includes an upper shell 143 and a lower shell 144. The upper shell 143 is connected to the lower shell 144 to define an installation cavity 1443. The winder may be disposed within the installation cavity 1443. Thus, when the winder is mounted inside the shell 141, the winder may be first placed in the lower shell 144, then the upper shell 143 is arranged on the lower shell, and then the upper shell 143 and the lower shell 144 are fixedly connected to each other, such that the winder may be fixed inside the shell 141.
Referring to FIGS. 2 to 8, in some embodiments, the shell 141 has an outlet hole 145 through which the elastic rope 110 passes. The outlet hole 145 has an rounded corner. It should be noted that, during the use, the elastic rope 110 is adapted to be in a frictional contact with the shell 141, which may reduce the structural strength of the elastic rope 110 and thereby influence the safety of the elastic rope 110. By providing the outlet hole 145 with an rounded corner which is suitable for contacting with the elastic rope 110, the friction between the shell 141 and the elastic rope 110 can be reduced, the structural strength of the smart wall pulley 100 can be improved, and thus the safety and stability of the smart wall pulley 100 can be improved. Further, a radius of the rounded corner is set to 3 mm to 6 mm, such that the rounded corner can be more fitted to the elastic rope 110, thereby further reducing the friction between the shell 141 and the elastic rope 110. Moreover, the relatively small radius of the rounded corner enables the rounded corner to better confirm to the shell 141, which can improve the production efficiency of the shell 141.
As shown in FIGS. 12-20, the adjuster 140 may further include a ratchet gear assembly 43. The ratchet gear assembly 43 is connected to the shell 141. The ratchet gear assembly 43 is configured to selectively fix or release the winding post 142 to adjust the length of the smart wall pulley 100.
As shown in FIGS. 12-19, the ratchet gear assembly 43 may include a gear 431, a ratchet 432, and a toggle handle 433. The gear 431 is provided on the winding post 142, and may rotate coaxially with the winding post 142. The ratchet 432 is configured to mesh with the gear 431. The toggle handle 433 is provided outside the shell 141 for a user to toggle. The toggle handle 433 is fixedly connected to the ratchet 432. When the toggle handle 433 is toggled, the toggle handle 433 drives the ratchet 432 to rotate. In this way, the ratchet 432 may be disengaged from the gear 431, the winding post 142 is rotatable, and the elastic rope 110 is movable around the winding post 142 to adjust a distance between one end of the elastic rope 110 and the adjuster 140. Through the provision of the toggle handle 433, the length of the smart wall pulley 100 can be adjusted by the user conveniently, and the structural stability of the ratchet gear assembly 43 is high when no adjustment is required.
For example, each of the ratchet 432 and the gear 431 has a plurality of teeth arranged at intervals. When the toggle handle 433 is in an initial state, at least one tooth of the ratchet 432 is located between and abuts against two adjacent teeth of the gear 431, and at least one tooth of the gear 431 is located between and abuts against two adjacent teeth of the ratchet 432. In this way, the ratchet 432 and the gear 431 may restrict each other. At this point, the winding post cannot rotate either, because the gear 431 rotates coaxially with the winding post 142. The toggle handle 433 is configured to disengage the gear 431 from the ratchet 432 or disengage the ratchet 432 from the gear 431. In this way, the winding post can be rotated so as to adjust the length of the smart wall pulley 100. With the arrangement of the gear 431 and the ratchet 432, a stepwise adjustment of the smart wall pulley 100 is achieved. Of course, in other embodiments, the ratchet gear assembly 43 may further include a pawl or the like to achieve a stepless adjustment of the ratchet gear assembly 43. In the description of the present disclosure, the term “a plurality of” means two or more.
In some embodiments, the ratchet gear assembly 43 further includes a restoration member 434 connected to the ratchet 432, so as to drive the ratchet 432 to mesh with the gear 431 constantly. In this way, it may be not necessary for a user to, after adjusting the length of the smart wall pulley 100, control the toggle handle 433 to be reset by himself, thereby reducing operation steps of the user. For example, the restoration member 434 may be provided with a mounting post. The restoration member 434 may be connected to the mounting post to drive the ratchet 432 to mesh with the gear 431 constantly.
According to an embodiment of the present disclosure, as shown in FIGS. 15-16, 18 and 19, a connecting post 50 is connected between the ratchet 432 and the toggle handle 433. The connecting post 50 is provided with a plurality of ribs to improve structural reliability. The plurality of ribs are spaced apart along a circumferential direction of the connecting post 50. For example, the ratchet 432 may be provided with a plurality of avoiding slots distributed at intervals along the circumferential direction of a through hole 4324. The connecting post may have a plurality of protrusions arranged corresponding to avoiding slots. Alternatively, with reference to FIGS. 15-16, 18 and 19, the connecting post 50 is provided with a plurality of avoiding slots 51, and the ratchet 432 is provided with protrusion(s) 4323. The protrusion can extend into the avoiding slot. Because of the provision of the avoiding slot, when the connecting post 50 rotates, the protrusion is driven to move together with the connection post 50. In this way, the reliability of the connecting post 50 driving the ratchet 432 to rotate can be improved.
The restoration member 434 is a torsion spring with which the connecting post 50 is sleeved. One end of the torsion spring abuts against the shell 141, and the other end of the torsion spring abuts against the toggle handle 433. By the arrangement of the torsion spring, the toggle handle 433 can restore slowly under the acting force of the torsion spring, thereby reducing operation steps of adjusting the smart wall pulley 100 performed by a user. For example, the torsion spring may have a mounting part 4341 extending towards the shell 141, the shell 141 may have a mounting hole or a mounting groove, and the mounting part 4341 may extend into the mounting hole or the mounting groove to improve the reliability of mounting the torsion spring to the shell 141.
For example, when the toggle handle 433 is in the initial state, referring to FIG. 15, the ratchet 432 and the gear 431 restrict each other. When the user pulls the smart wall pulley 100, the winding post 142 does not rotate. When the user wants to adjust the length of the smart wall pulley 100, he can toggle the toggle handle 433, and the restoration member 434 can rotate together with the toggle handle 433. At the same time, the connecting post 50 of the toggle handle 433 can drive the ratchet 432 to move, so as to separate the ratchet 432 from the gear. At this point, referring to FIG. 16, the ratchet 432 do not restrict the gear 431, such that the winding post 142 can be rotated. The user can rotate the winding post 142 by an action such as pulling the elastic rope 110, at the same time, the elastic rope 110 may be wound or released. In this way, the length of the smart wall pulley 100 may be changed, thereby achieving an adjustable length of the smart wall pulley 100. When the user stops toggling the toggle handle 433, under the action of the restoration member 434, the toggle handle 433 can restore slowly until recovering the initial state in which the ratchet 432 and the gear 431 restrict each other, such that the winding post 142 does not rotate. In this way, the length adjustment of the smart wall pulley 100 is completed.
In some embodiments, the toggle handle 433 includes a connecting part 4331 and a toggling part 4332 connected to the connecting part 4331. The connecting part 4331 is connected to the ratchet 432. The toggling part 4332 is in a shape of a long strip so as to facilitate the toggling by the user. Further, the connecting part 4331 can be in a circular shape which is different from that of the ratchet 432, thereby facilitating user operation.
For example, the smart wall pulley 100 may be provided with a pull ring 90 at each of its two ends. The user may grasp the pull ring 90 at one end by his/her hand, and may tie the pull ring 90 at the other end on his/her ankle to perform physical exercises. Alternatively, the user may grasp the pull ring 90 at one end by his/her hand, and mount the pull ring 90 at the other end to an object with a heavier weight to perform physical exercises. Of course, the smart wall pulley 100 may have a plurality of use ways, which are not limited herein.
In some examples, as shown in FIGS. 14-16, the ratchet 432 includes a main body part 4321 and a meshing part 4322 connected to the main body part 4321. The main body part 4321 is connected to the toggle handle 433, and the meshing part 4322 is configured to mesh with the gear 431 to ensure the reliability of the mutual restriction between the ratchet 432 and the gear 431. The main body part 4321 may have a through hole 4324 through which the connecting post 50 passes, such that the connecting post 50 and the ratchet 432 are assembled, and the connecting post 50 can drive the ratchet 432 to rotate, and meanwhile, the mounting reliability of the connecting post 50 and the ratchet 432 can be improved.
According to an embodiment of the present disclosure, the ratchet 432 and the toggle handle 433 are integral with each other, so as to simplify the steps, facilitate the assembly, improve the assembly efficiency, and improve structure stability and reliability. Alternatively, the ratchet 432 may be connected to the toggle handle 433 by a screw. Any of the above manners can effectively ensure the movement consistency of the ratchet 432 and the toggle handle 433. Of course, there may be a plurality of manners for the fitting of the ratchet 432 and the toggle handle 433, which are not limited herein.
In some embodiments, referring to FIG. 17, the shell 141 may include an upper shell 143 and a lower shell 144 connected to the upper shell 143. One end of the winding post 142 is connected to the lower shell 144, and the other end of the winding post 142 extends towards the upper shell 143, which may facilitate disassembly and assembly of the smart wall pulley 100.
The upper shell 143 may have a positioning groove (not shown), and the other end of the winding post 142 is located in the positioning groove, such that the reliability of the connection between the winding post 142 and the upper shell 143 can be improved. Of course, the upper shell 143 or the lower shell 144 may also include a positioning post 4111 sleeved with the winding post 142. In this way, on one hand, positioning and mounting may be facilitated and the connection is stable. On the other hand, when the winding post 142 rotates, the positioning post 4111 may prevent the winding post 142 from displacing in an axial direction, which would otherwise cause the winding post 142 to be disengaged from the upper shell 143.
In some embodiments, a plurality of screw posts 4112 are provided in the upper shell 143, and extend towards the lower shell 144. The upper shell 143 and the lower shell 144 may be connected by screws which are connected to the screw posts 4112. For example, the lower shell 144 may also be provided with a plurality of screw posts 4112, so as to further improve the installation reliability. The screws may pass into the screw posts 4112 of the upper shell 143 and the screw posts 4112 of the lower shell 144 to fix the upper shell 143 and the lower shell 144 together. Alternatively, the upper shell 143 and the lower shell 144 are connected in a snap-fit manner. Of course, in other embodiments, the upper shell 143 and the lower shell 144 may be mounted to each other by a plurality of manners, which are not limited herein.
For example, in conjunction with FIGS. 12-14, 19 and 20, the lower shell 144 can further include a first lower shell 4121 and a second lower shell 4122. The first lower shell 4121 and the second lower shell 4122 can be fixed by a plurality of fasteners 80 to ensure the mounting reliability of the first lower shell 4121 and the second lower shell 4122. The second lower shell 4122 is disposed between the toggle handle 433 and the first lower shell 4121. The connecting post 50 may have a first connecting end 52 and a second connecting end 53, and the first connecting end 52 may extend into the through hole 4123 of the second lower shell 4122 to improve the mounting reliability of the lower shell 144 and the connecting post 50. The diameter of the first connecting end 52 may be smaller than the diameter of the second connecting end 53 to form a step part 54. In this way, on the one hand, the diameter of the through hole 4123 may be reduced, thereby ensuring the structural reliability of the lower shell 144, and on the other hand, the step part 54 may avoid the bottom wall of the through hole 4123, so as to prevent the second lower shell 4122 from coming into contact with the connecting post 50, which would otherwise generate friction. The avoiding slot 51 may be disposed at the second connecting end 53, and the structure reliability of the second connecting end 53 thus disposed is better.
The motion sensing detection device 10 of the smart wall pulley 100 according to an embodiment of the present disclosure will be described below with reference to FIGS. 21 to 26. The motion sensing detection device 10 can be applied to the smart wall pulley 100, so as to detect a motion state of the smart wall pulley 100 when used by a user.
As shown in FIGS. 21, 22 and 24, the motion sensing detection device 10 may mainly include a protective shell 11, a circuit board 16, a switch 17, and a button 20. A relatively sealed accommodating cavity 14 is formed in the protective shell 11. Further, the protective shell 11 is provided, on its surface, with a button hole 15 communicating with the accommodating cavity 14. The circuit board 16 and the switch 17 are both mounted in the relatively sealed accommodating cavity 14 in the protective shell 11. The protective shell 11 may be made of a relatively hard material. In this way, the protective shell 11 can not only prevent a foreign substance from entering the accommodating cavity 14, which would otherwise damage the circuit board 16 and the switch 17. In addition, when the motion sensing detection device 10 is impacted by an external force, the protective shell 11 can protect the circuit board 16 and the switch 17 from damage. Thus, the structural reliability of the motion sensing detection device 10 can be improved, which can extend the service life of the motion sensing detection device 10.
As shown in FIG. 24, the circuit board 16 may be configured to sense and detect motion. The switch 17 may be disposed on the circuit board 16, and the switch 17 may correspond to the button hole 15. The switch 17 may selectively control the circuit board 16 to be on or off. Specifically, when the smart wall pulley 100 is in the use state, the user may control the switch 17 to turn on the circuit board 16, such that the circuit board 16 can sense and detect the movement of the user. When the user does not use the smart wall pulley 100, the user can control the switch 17 to be off, so that the circuit board 16 stops operating. In this way, it can effectively save energy consumption of the motion sensing detection device 10 without affecting the normal operation of the motion sensing detection device 10, which can extend the service life of the motion sensing detection device 10 and thus improve the use experience of the user.
As shown in FIG. 22, the button 20 is an elastic button, and is disposed in the button hole 15. The button 20 may mainly include a pressing part 21, a pressure delivering part 22, and a first sealing part 23. The pressing part 21 has a pressing surface 24. The first sealing part 23 is provided at an outer circumferential edge of the pressing part 21, and can cooperate with an outer circumferential wall of the button hole 15 sealingly. The pressure delivering part 22 is provided within the first sealing part 23. The pressing part 21 cooperates with the switch 17 through the pressure delivering part 22. When a user presses the pressing surface 24 of the pressing part 21, the pressing part 21 elastically deforms towards a side close to the pressure delivering part 22, and presses the pressure delivering part 22. The pressure delivering part 22 being pressed elastically deforms towards a side where the switch 17 is located. In this way, the switch 17 is triggered and thus is controlled to turn on or off the circuit board 16. After the user stops applying the force to the pressing part 21, the pressing part 21 and the pressure delivering part 22 will resile to an initial position, so as to restore to their original shapes for the next pressing operation of the user. In this way, it not only achieves a simple and direct control of the switch 17 by the user, but also a stable and reliable structure of the button 20, thereby avoiding the button 20 from malfunctioning after being pressed multiple times by the user and thus ensuring the reliability of the button 20.
Further, as shown in FIG. 22 and FIG. 23, the first sealing part 23 sealingly cooperates with the outer circumferential wall of the button hole 15, thus a gap between the button hole 15 and the button 20 may be sealed, and further, the circuit board 16 and the switch 17 may be isolated from the outside. Therefore, it can prevent effectively the external water or foreign matters from entering the accommodating cavity 14 through the gap between the button 20 and the button hole 15, which would otherwise damage components in the accommodating cavity 14. In this way, the reliability of the motion sensing detection device 10 is further improved without affecting the normal operation of the button 20.
Thus, by the sealing cooperation between the first sealing part 23 of the button 20 and the outer circumferential wall of the button hole 15, the external water can be effectively prevented from entering the accommodating cavity 14 of the protective shell 11 through the button hole 15, such that the waterproofness of the motion sensing detection device 10 can be improved, and the reliability of the motion sensing detection device 10 can be improved.
As shown in FIGS. 22 and 23, the first sealing part 23 is provided with one of a sealing groove and a sealing protrusion. The protective shell 11 is provided with the other one of the sealing groove and the sealing protrusion at the button hole 15. The sealing protrusion is fitted into the sealing groove, such that when the button 20 is disposed in the button hole 15, the sealing protrusion may protrude into the sealing groove, and the sealing protrusion may abut against the sealing groove. In this way, it can not only achieve the connecting and fixing of the button 20 in the button hole 15, but also improve the leakproofness between the button 20 and the button hole 15. Thus, it can prevent effectively the external water from flowing into the accommodating cavity 14 through a gap between the button 20 and the button hole 15, and thus can improve the structural reliability of the motion sensing detection device 10. In addition, such an abutment is simple and convenient without requiring any auxiliary tool, which can simplify the structure and production of the motion sensing detection device 10.
As shown in FIGS. 22 and 23, a surface at a side of the sealing protrusion facing towards the accommodating cavity 14 is a first sealing inclined surface 25. A sidewall at a side of the sealing groove facing towards the accommodating cavity 14 is a second sealing inclined surface 26. The first sealing inclined surface 25 and the second sealing inclined surface 26 sealingly cooperate with each other. After the sealing protrusion protrudes into the sealing groove and abuts against the sealing groove, the first sealing inclined surface 25 of the sealing protrusion and the second sealing inclined surface 26 of the sealing groove are in close contact with each other. In this way, it can further improve the leakproofness between the button 20 and the button hole 15 and thus can further improve the waterproofness of the motion sensing detection device 10, which can further improve the reliability of the motion sensing detection device 10.
As shown in FIG. 24, the circuit board 16 is provided with a light-emitting element. The light-emitting element corresponds to the button hole 15, and the button 20 is light transparent to transmit light emitted by the light-emitting element. When a user presses the button 20 to turn on or off the circuit board 16, the light-emitting element on the circuit board 16 may inform the user whether the turn-on or turn-off control on the circuit board 16 is successful, and may further inform the user of the current working state of the circuit board 16. For example, when the light-emitting element emits light, the circuit board 16 is in a working state. When the light-emitting element goes out, the circuit board 16 is in an off state. When starting to use the smart wall pulley 100, the user may press the button 20. The switch 17 is triggered by the button 20 to turn on the circuit board 16. Thus, the light-emitting element emits light, which can inform the user that the circuit board 16 is turned on successfully. When the user stops using the smart wall pulley 100, the user may press the button 20. The switch 17 is triggered by the button 20 to turn off the circuit board 16. Thus, the light-emitting element goes out, which may inform the user that the circuit board 16 is turned off successfully. In this way, the structural reliability of the motion sensing detection device 10 can be improved.
Further, since the button 20 is light transparent, the user can directly observe the light emitting and going out of the light-emitting element through the button 20, so that the user can more intuitively observe an on or off state of the circuit board 16, which can improve the use experience of the user. The button 20 may be made of a transparent rubber material, which can not only ensure the high transparency of the button 20, but also ensure good elasticity of the button 20, thereby facilitating the user's pressing operation on the button 20 and restoration of the button 20.
As shown in FIGS. 24 and 25, the protective shell 11 is provided with a plug hole 29. The motion sensing detection device 10 further includes a plug connector 28 and a sealing plug 30. The plug connector 28 is arranged on the circuit board 16, and is spaced apart from the switch 17. The plug connector 28 is correspondingly disposed within the plug hole 29. The sealing plug 30 is mounted at the plug hole 29 in an openable and closeable manner. The plug connector 28 and the circuit board 16 cooperate with each other to complete corresponding functions of the motion sensing detection device 10. The sealing plug 30 may seal the plug hole 29, so as to prevent the external water from entering the accommodating cavity 14 through the plug hole 29, which would otherwise damage the components in the accommodating cavity 14. Further, the sealing plug 30 may be mounted at the plug hole 29 in an openable and closeable manner. In this way, the sealing plug 30 can seal the plug hole 29 effectively, and at the same time, facilitate the user to open the sealing plug 30 for repairing or replacing the plug connector 28, and optimize the structural design of the motion sensing detection device 10, thereby improving the use experience of the user.
As shown in FIGS. 25 and 26, the sealing plug 30 may mainly include a fixing part 31, a connecting part 32 and a second sealing part 33. The connecting part 32 is connected between the fixing part 31 and the second sealing part 33. The fixing part 31 is fixed in the accommodating cavity 14, and the second sealing part 33 is configured to seal the plug hole 29 in an openable and closeable manner. The installation and fixing of the sealing plug 30 can be realized by the installation and fixing of the fixing part 31 in the accommodating cavity 14. The second sealing part 33 may seal the plug hole 29, which can prevent effectively external water and foreign matters from entering the accommodating cavity 14 through the plug hole 29, which can further improve the waterproofness of the motion sensing detection device 10. The sealing plug 30 is provided with a buckle at one end away from the connecting part 32. The user can implement the installation and disassembly of the sealing plug 30 by using the buckle. Thus, the second sealing part 33 may seal the plug hole 29 in an openable and closeable manner, thereby improving the use experience of the user. In addition, the fixing part 31, the connecting part 32 and the second sealing part 33 may integral with each other, so that not only the production process can be simplified, but also the structural strength of the sealing plug 30 can be improved.
As shown in FIGS. 25 and 26, the sealing plug 30 can further mainly include a restricting part 34. The restricting part 34 is provided on a side of the second sealing part 33 facing towards the plug connector 28. The restricting part 34 may be spaced apart from the connecting part 32. The restricting part 34 cooperates with and restricts the plug connector 28, thus the restricting part 34 can play a role in fixing and restricting the plug connector 28 and achieve a more stable and firm installation of the plug connector 28. It can prevent the plug connector 28 from loosening or dropping due to a larger force applied to the motion sensing detection device 10 when the user uses the motion sensing detection device 10, which can further improve the structural reliability of the motion sensing detection device 10. In addition, the restricting part 34 and the connecting part 32 being spaced part can make the gravity distribution of the sealing plug 30 more uniform, improving the stability of the sealing plug 30.
As shown in FIG. 21, the protective shell 11 may mainly include a first protective shell 12 and a second protective shell 13. The first protective shell 12 and the second protective shell 13 are arranged facing each other, and may define the accommodating cavity 14. In this way, it can not only facilitate the installation and arrangement of the protective shell 11, but also provide convenience for a user to open the protective shell 11 so as to repair or replace components in the accommodating cavity 14, thus the use experience of the user may be improved. Further, because there may be a gap at a junction between the first protective shell 12 and the second protective shell 13. A sealing ring 35 for sealing is provided at edges of the first protective shell 12 and the second protective shell 13 surrounding the accommodating cavity 14. The sealing ring 35 can effectively seal the edge of the accommodating cavity 14, which can prevent external water from entering the accommodating cavity 14 from the edge of the accommodating cavity 14 so as to prevent the components in the accommodating cavity 14 being damaged. Thus, the waterproofness of the protective shell 11 can be further improved, and thus the structural reliability of the motion sensing detection device 10 can be further improved.
As shown in FIGS. 21 and 24, one of the first protective shell 12 and the second protective shell 13 is provided with an accommodating groove at the edge surrounding the accommodating cavity 14, and the other of the first protective shell 12 and the second protective shell 13 is provided with a restricting protrusion 19. The sealing ring 35 is disposed in the accommodating groove, and the restricting protrusion 19 can protrude into the accommodating groove. In this way, it can not only restrict and fix the sealing ring 35, but also achieve a fixed connection between the first protective shell 12 and the second protective shell 13. In addition, the sealing ring 35 can seal the gap between the restricting protrusion 19 and the restricting groove, which can prevent external water and foreign matters from entering the accommodating cavity 14 through the gap between the restricting protrusion 19 and the restricting groove and thus prevent the components in the accommodating cavity 14 being damaged, and further improve the waterproofness of the protective shell 11. Thus, the structural reliability of the motion sensing detection device 10 can be further improved.
As shown in FIG. 21, the smart wall pulley 100 according to the present disclosure may mainly include an elastic rope and the motion sensing detection device 10 described above. The motion sensing detection device 10 may be provided at an end of the elastic rope, and may sense and detect a use condition of the elastic rope by a user, thereby improving the use experience of the user.
