Meanwhile, the assembled height adjustable table is more visually pleasing.

In some embodiments, the first terminal block 1 is a pogo pin assembly or a contact set corresponding to a pin head of the pogo pin assembly.

Optionally, as shown in FIG. 2, the first terminal block 1 is the contact set corresponding to the pin head of the spring head assembly. In FIG. 2, the contact set is located at the bottom face of the tabletop, and the contact set is approximately flush with the height of the bottom face of the tabletop 6, thus making the whole tabletop assembly more flat and more convenient for the package and transportation of the tabletop assembly.

In some embodiments, as shown in FIGS. 1-8, the number of at least two first terminal block 1 is two. Corresponding wiring modes of the plurality of first electric connection contacts 11 located at the two first terminal blocks 1 are configured to be circumferentially and symmetrically arranged along the center of the tabletop 6. In this embodiment, the wire connecting mode of the first terminal block 1 is specifically arranged, so that a routing form of another first terminal block 1 may be obtained after rotating a routing form of one first terminal block 1 by 180 degrees along the center of the tabletop 6. By means of such arrangement mode, after receiving the tabletop assembly, the consumer may directly assemble the tabletop assembly according to an assembling position corresponding to the lifting frame without distinguishing the left-right direction or the front-back direction, thus the assembly difficulty for the user is greatly reduced.

In some embodiments, as shown in FIGS. 1-2, two grooves 62 are formed in the bottom face of the tabletop 6, the two grooves 62 are respectively communicated with the wiring ducts 61 to accommodate end part regions of the cable 7, and the first terminal block 1 is the contact set. The height adjustable table further comprises two wiring boards 63 corresponding to the two grooves 62, the two wiring boards 63 are pressed against and covered onto the grooves 62, the contact set is located at one side, away from the tabletop 6, of the wiring board 63, and the cable 7 located in the groove 62 is electrically connected to the contact set through the other side of the wiring board 63. To facilitate the connection of the cable 7 to the first terminal block 1, the groove 62 is formed in the extending end of the wiring duct 61 and corresponds to the position of the first terminal block 1, when the cable 7 is arranged in the wiring duct 61, the trend of the cable 7 is consistent with an extending direction of the wiring duct 61, and when the end part of the cable 7 is connected to the first terminal block 1, the cable 7 needs to rotate by 90 degrees towards the bottom of the tabletop 6, so that the groove 62 formed in the extending end of the wiring duct 61 in this embodiment may provide a sufficient space for the steering and connection of the cable 7.

Specifically, when the cable 7 is connected to the first terminal block 1, the contact located at the wiring board 63 may be firstly connected to the cable 7, and then the wiring board 63 is pressed against and covered onto the position of the groove 62. At the moment, the extra length of cable 7 may be coiled in the groove 62.

In an alternative implementation mode, the tabletop assembly in above embodiment may be assembled with the lifting frame assembly of this embodiment. As shown in FIGS. 1-8, the lifting frame assembly of this embodiment may be used for the height adjustable table, the lifting frame assembly comprises a tabletop support 52 and at least two supporting parts 51, and the tabletop support 52 is used for being connected to the tabletop 6 of the lifting frame. A driving unit 4 is arranged in each of the supporting parts 51, each of the supporting parts 51 comprises a second terminal block 2, and the second terminal block 2 is provided with a plurality of second electric connection contacts 21; the second electric connection contacts 21 are at least partially located outside the supporting parts 51, and the second terminal blocks 2 are electrically connected to the driving unit 4. Wherein the supporting parts 51 are movably connected to the tabletop support 52, when the supporting parts 51 move to an installation position with respect to the tabletop support 52, the second terminal block 2 moves to a connection position accordingly and is connected to the first terminal block 1 of the tabletop assembly, and when the supporting parts 51 are located at a folding position with respect to the tabletop support 52, the supporting parts 51 are in a folded date formed with the tabletop support 52.

It is easy to understand that the lifting frame assembly of this embodiment has two states, i.e., an installation state and a folded state. Different states of the supporting parts 51 during folding are respectively shown in FIG. 5 and FIG. 6. In FIG. 5, the supporting part 51 located at the left side is in a state of rotating towards another supporting part 51, and is finally rotated to a position shown in FIG. 6; and the rotation of the supporting part 51 located at the right side is approximately mirror-symmetric with respect to the left side, and will not be described again. The overall space occupation of the lifting frame assembly in the folded state is smaller, and meanwhile, the second electric connection contacts 21 at the outer side of each of the supporting parts 51 are also located in a triangular region (as shown by a dotted line in FIG. 6) formed by the supporting part 51 and the tabletop support 52. Therefore, the second terminal block 2 may be conveniently protected during transportation.

The lifting frame assembly may be changed to the installation state by respectively rotating the two supporting parts in the folded state towards two sides, and along with the rotation of the supporting parts 51 in this process, the second electric connection contacts 21 are gradually rotated to a position towards the tabletop support 52. At the moment, the second electric connection contacts 21 are arranged at a position opposite to the first terminal block 1 and are exposed to an outside region of the top of the supporting part 51 (as shown in FIG. 3). The tabletop assembly is assembled with a preset assembling position of the lifting frame assembly, and the second terminal block 2 in this state may be just in butt joint with the first terminal block 1.

In accordance with the lifting frame assembly of the embodiment of the present disclosure, the assembling operation of the height adjustable table is simplified by using the supporting parts 51 rotatably connected to the tabletop support and the first terminal block 1 and the second terminal blocks 2 provided in pairs. On the one hand, during transportation, part of the height adjustable table part may be disassembled into a lifting frame to be packaged and transported, thus reducing the size of the package, and greatly reducing the logistic cost. Meanwhile, the lifting frame assembly may also be folded, the second terminal block 2 on the lifting frame assembly in the folded state forms an approximate fan-shaped region with the tabletop support 52, so that the second terminal block 2 may be protected during transportation. On the other hand, after receiving the goods, the consumer may assemble the tabletop assembly and the lifting frame assembly through a simple process, the assembly difficulty is reduced. Moreover, installation and wiring operations of electric appliance parts are omitted, so that the whole height adjustable table is more visually pleasing, and the user experience is improved.

Alternative, the second terminal block 2 of this embodiment comprises but is not limited to an aviation plug or a pogo pin and other electric connectors. The aviation plug is also called aviation connector, which has characteristics of water and moisture resistance and corrosion resistance. In accordance with the aviation plug of this embodiment, the number of pins of the aviation plug may be selected according to connection demands of electric appliances of the height adjustable table, for example, the aviation plug with having three, six or twelve pins is selected. The pogo pin is an electric connector applied to the fields of automobiles, medicals, aerospace, and the like, the internal of which is provided with a precise spring-like structure, and the pin head position may deform telescopically when the pogo pin is pressed. The number of pins of the pogo pin may also be selected according to actual use demands. When the second terminal block 2 of this embodiment is the aviation plug (one of a male contact element and a female contact element), the first terminal block 1 opposite to the second terminal block is arranged as another aviation plug (one of the female contact element or the male contact element) paired with the second terminal block, and the aviation plug may be arranged at an outside region adjacent to the supporting part 51. When the lifting frame assembly is assembled with the tabletop assembly, mechanical structures of the lifting frame assembly and the tabletop assembly may be firstly assembled together, and then the corresponding aviation plugs are plugged together. To keep concise and visually pleasing appearance of the height adjustable table, the aviation plug may be arranged at one side, close to the center of the tabletop, of the supporting part 51. Meanwhile, the length of a connecting wire for the aviation plug reserved at outside of each supporting part 51 may be configured to just meet a plugging demand, thus reducing the size exposed to the outside of the supporting part 51 as much as possible.

In some embodiments, as shown in FIGS. 1-8, each of the supporting parts 51 further comprises a driving box 512 and a table leg 511, the driving unit 4 is arranged in the driving box 512, and the plurality of second electric connection contacts 21 are partially arranged outside the driving box 512. Meanwhile, the table leg 511 is fixedly connected to the bottom of the driving box 512. The table leg 6 in this embodiment is connected to the tabletop support 52 through the driving box 512, and the driving box 512 may be used for preventing the driving unit 4 from being affected by factors such as external force or dust during use or transportation.

Further, the plurality of second electric connection contacts 21 may be distributed on the top face of the driving box 512. In this embodiment, when each of the supporting parts 51 is in the installation state, the plurality of second electric connection contacts 21 located at the top of the driving box 512 may be in the position towards the tabletop assembly, so that the first terminal block 1 may be in butt joint with the second terminal block 2 when the tabletop assembly is pressed against and covered onto the lifting frame assembly.

Further, as shown in FIGS. 3-4, a plurality of through holes 5121 may be formed in a top wall of the driving box 512, the second terminal block 2 is arranged at the inner side of the top of the driving box 512, thus making the plurality of second electric connection contacts 21 extend out of the plurality of through holes 5121. In this embodiment, the second wiring terminal 2 and the driving unit 4 are arranged in the driving box 512 together, the through holes are further formed in the top wall of the driving box 512 to make the second terminal block 2 in butt joint with the first terminal block 1 during installation, thus making the second electric connection contacts 21 extend out of the through holes 5121.

Further, the driving box 512 may be provided with a first end part 5122 and a second end part 5123 in opposite arrangement, the table leg 511 is connected to the bottom face of the first end part 5122, and the second end part 5123 is hinged to the tabletop support 52, and the second end part 5123 is provided with a fixing part 5124 for being fixedly connected to the tabletop support 52 in the installation state. In this embodiment, the table leg 511 is rotatably connected to the tabletop support 52 through the driving box 512, when the table leg 511 is in the installation state, the supporting part 51 and the tabletop support 52 are locked with each other by using the fixing part 5124, thus making the whole lifting frame assembly in a stable state.

In some embodiments, as shown in FIGS. 1-7, the second terminal block 2 is a pogo pin assembly or a contact set corresponding to a pin head of the pogo pin assembly. To achieve rapid assembling of the tabletop assembly and the lifting frame assembly, a connection mode of the first terminal block 1 and the second terminal block 2 is configured to be the connection of the pogo pin assembly and the corresponding contact set in this embodiment. When the second terminal block 2 is one of the pogo pin assembly or the contact set, the first terminal block 1 needs to be set as another.

Further, the tabletop support 52 is provided with a positioning face 53, the positioning face 53 is located in at least part of the region of the top of the supporting parts 51, and the positioning face 53 is in fit with the bottom face of the tabletop. In this embodiment, the second terminal block 2 is the pogo pin assembly, when the supporting parts 51 move to an installation position, a direction of the pin head of the pogo pin assembly is perpendicular to the positioning face 53, and the pin head of the pogo pin assembly is higher than the positioning face 53. In this embodiment, when the lifting frame assembly is assembled with the tabletop assembly, the pin head of the pogo pin moves downwards under the pressure of the contact set located at the tabletop, therefore, after the bottom face of the tabletop 6 is in contact with the positioning face 53, the pin head is kept at a state abutting against the contact under the action of elastic force, thus achieving electric connection of the tabletop assembly and the lifting frame assembly.

In some embodiments, as shown in FIGS. 1-7, the number of at least two supporting parts 51 is two, corresponding wiring modes of the plurality of second electric connection contacts 21 respectively located at the two supporting parts 51 are configured to be circumferentially and symmetrically arranged, and the circumference is perpendicular to height directions of the supporting parts 51 and takes the two supporting parts 51 as end points of a diameter. In this embodiment, the plane where the circumference is located is parallel to the bottom face of the tabletop 6, and the second electric connection contacts 21 of another supporting part 51 may be formed by rotating the corresponding wiring mode of the second electric connection contacts 21 located at one supporting part 51 by 180 degrees along the circumference.

Specifically, the second electric connection contacts 21 in symmetric arrangement are shown in FIG. 7, and a region IV in the figure is the position of the center of circle of the circumference of this embodiment. Ten second electric connection contacts 21 are provided on each of the two supporting parts, and are distributed in a rectangular array of 2×5. The driving unit 4 comprises two drivers 41, and the driver 41 may be a motor. By taking the three electric connection contacts in regions I, II and III shown in the figure as an example, the region I in the figure may be connected to a forward contact of the motor, the region II may be connected to a reverse contact of the motor, and the region III may be connected to an earth wire.

In some embodiments, as shown in FIGS. 1-8, the number of at least two supporting parts 51 is two. The tabletop support 52 comprises two cross beams 521, two ends of each of the cross beams 521 are provided with two fixed connection points 55 and two hinge points 54, and the two hinge points 54 are located at inner sides of the two fixed connection points 55. The two supporting parts 51 are configured to be clamped in middle positions of the two cross beams 521, are hinged to the cross beams 521 through the hinge points 54, and are fixedly connected to the cross beams 521 through the fixed connection points 55. In this embodiment, the supporting parts 51 may be hinged to the cross beams through the hinge points 54 before delivery so as to guarantee that the supporting parts 51 are in a rotatable state. After receiving the goods, the user rotates the supporting parts 51 to make the supporting parts 51 be fixedly connected to the cross beams through the fixed connection points 55.

It should be understood that the two hinge points in this embodiment are located at the inner sides of the two fixed connection points. Therefore, when each of the supporting parts 51 is rotated towards the inner side, the second terminal block 2 may sweep a roughly fan-shaped region, so that the second terminal block 2 is hidden in a region formed by the cross beam 521 and the supporting part 51 (the position shown by a dotted line in FIG. 6) during packaging and delivery, and at the moment, the second terminal block 2 faces the two sides of the lifting frame assembly, thus playing a role in protecting the second terminal block 2.

Further, the tabletop support 52 further comprises two girders 522, the middles of the two girders 522 are fixedly connected to two ends of the cross beams 521, respectively; each of the girders 522 is provided with a connection point 56, and the supporting parts 51 are fixedly connected to the girders 522 through the connection points 56. When the supporting parts 51 are fixed to the tabletop support 52, in this embodiment, the girders 522 are further provided with the connection points 56 to achieve a better fixation effect during the fixation of the supporting parts 51 and the tabletop support 52. The connection point 56 on each of the girders 522 is located at one side, away from the hinge point 54, of the fixed connection point 55, thus forming three-point positioning by the connection point 56, the fixed connection point 55 and the hinge point 54 in a horizontal direction in the installation state to form the fixation of the lifting frame assembly to the utmost extent.

Optionally, in above embodiments, the hinge points 54 and the fixed connection points 55 located on each of cross beams 521 may be simultaneously configured as racetrack-shaped positioning holes extending in a length direction of the cross beam 521 (as shown in an enlarged view in FIG. 5), so that the driving box 512 may also have a degree of freedom to move in the horizontal direction when the driving box 512 is connected to the cross beam 521. When the tabletop assembly and the lifting frame assembly are in an assembling stage, the second terminal block 2 located at the position of the driving box 512 may be fine-adjusted in the horizontal direction through the racetrack-shaped positioning holes, thus achieving a more accurate butt joint with the first terminal block 1.

Meanwhile, the connection point 56 of the above embodiment may also be arranged a recessed region (as shown in FIG. 3) formed by the bottom of the girder 522 recessed upwards, when the connection point 56 is used to connect the girder 522 to the driving box 512 using a screw, the screw and the driving box 512 may be pre-assembled before delivery. The screw may slide into the recessed region with the rotation of the supporting part 51 when assembled by the user. Therefore, the recessed region facing the below may make the connection of the girder 522 and the driving box 512 more concise. Meanwhile, when the racetrack-shaped positioning holes are used to adjust a horizontal position of the second terminal block 2, the second terminal block 2 may be precisely adjusted through the screw-in and screw-out of the bolt at the connection point 56.

In some embodiments, as shown in FIGS. 5-7, wherein each of the girders 522 is further provided a baffle 58, the baffle 58 is located in a middle region of the girder 522 and is arranged towards the top of the driving box 512. When the driving box 512 is rotated towards the tabletop support 52, the bottom of the baffle 58 just may be located above the driving box 512. The baffle 58 may effectively prevent the supporting part 51 from rotating excessively towards the above, thus facilitating the connection of the driving box 512 and the fixed connection point 55 and further simplifying the assembling difficulty for the user during assembly.
