Description of reference signs used in this disclosure may include:
The structure of the certain synchronization mechanism is relatively complicated, and once the size of the fan blade is adjusted, the synchronization mechanism needs to be replaced as a whole, which leads to high design cost and manufacturing cost of the hiding fan, and is not conducive to the subsequent maintenance of the hiding fan.
Therefore, it would be desirable to have a hiding fan that overcomes or at least alleviates the above-mentioned deficiencies.
The technical solutions disclosed in the various examples of the present disclosure are described in detail below in conjunction with the drawings.
An example of the present disclosure discloses a hiding fan. Referring to
The synchronization mechanism 300 includes a rotation ring 310 and a plurality of connection rods 320. The number of the connection rods 320 is equal to the number of the fan blades 200. The rotation ring 310 is mounted on the turntable 100, and the rotation ring 310 is configured to rotate relative to the turntable 100 around the central axis of the turntable 100.
Each fan blade 200 has an installation end and a free end, the installation end has an installation portion 210 and a connection portion 220 that are spaced apart from each other, the installation portion 210 is mounted on the turntable 100 through the first rotation connection portion 400; a first end of the connection rod 320 is mounted on the turntable 100 on the rotation ring 310 through a second rotation connection portion 500, a second end of the connection rod 320 is mounted on the connection portion 220 through a third rotation connection portion 600; the fan blades 200 is configured to rotate around the central axis of the first rotation connection portion 400, and the fan blades 200 is configured to switch between the storage position and the unfolded position by rotating.
In the hiding fan disclosed in the present disclosure, the plurality of fan blades 200 are connected to each other through a synchronization mechanism 300, so that each fan blade 200 is synchronously unfolded, or, synchronously folded and stored; the synchronization mechanism 300 includes a rotation ring 310 and a connection rod 320; for hiding fans of different sizes, it is only required to change the size of the connection rod 320, so that the same rotation ring 310 can adapt to hiding fans of different sizes, reducing the design cost and manufacturing cost of the hiding fan, and facilitating the subsequent maintenance of the hiding fan.
The structures of the first rotation connection portion 400, the second rotation connection portion 500 and the third rotation connection portion 600 may be appropriately selected according to actual needs. Referring to
Optionally, referring to
Referring to
Optionally, the hiding fan has a position limit structure, and the position limit structure includes a unfolded position limit portion and a storage position limit portion, so that the fan blade 200 can only rotate between the unfolded position and the storage position, so as to prevent the rotation of the fan blades 200 from exceeding an expected range and improve the stability and reliability of the hiding fan. The specific structure of the position limit structure may be appropriately selected according to actual needs, for example, an arc-shaped positon limit groove is provided on the rotation ring 310, and the turntable 100 has a protrusion block inserted into the arc-shaped positon limit groove; in the case where the fan blades 200 are in the unfolded position, the protruding block abuts against one end of the arc-shaped limiting slot; in the case where the fan blades 200 are in the storage position, the protruding block abuts against the other end of the arc-shaped limiting slot.
Referring to
Optionally, the turntable 100 includes an annular installation seat 130, the rotation ring 310 is sleeved on the outer side of the annular installation seat 130; the first position limit structure 131 is arranged on the annular installation seat 130, the second position limit structure 312 is arranged on the rotation ring 310; the first position limit structure 131 is a first position limit protrusion protruding toward the rotation ring 310 along a radial direction of the turntable 100, and the second position limit structure 312 is a second position limit protrusion protruding toward the annular installation seat 130 along the radial direction of the turntable 100; in the case that the fan blades 200 are in the unfolded position, the first position limit protrusion and the second position limit protrusion abut against each other, so as to prevent the fan blades 200 from continuing to rotate toward the direction which makes the fan blades 200 be unfolded.
The fourth position limit structures 230 are respectively arranged on the fan blades 200, the third position limit structure 120 is a third position limitation protrusion protruding toward the fan blades 200 along a thickness direction of the turntable 100, and the fourth position limit structure 230 a fourth position limitation protrusion protruding toward the turntable 100 along a thickness direction of the turntable 100. In the case where the fan blades 200 are in the storage position, the third position limitation protrusion and the fourth position limitation protrusion abut against each other, so as to prevent the fan blades 200 from continuing to rotate toward the direction which makes the fan blades 200 be folded and stored. The above-mentioned unfolded position limit portion and storage position limit portion are simple in structure, require less space for arrangement, and facilitate the arrangement of the position limit structure.
Optionally, the hiding fan further includes an elastic reset member (not shown in the figures), the elastic reset member includes a first installation portion and a second installation portion; the first installation portion is fixed relative to the turntable 100, and the second installation portion is fixed relative to the fan blades 200. The elastic reset member applies an elastic force to the fan blades 200 to keep the fan blades 200 in the storage position; once the fan blades 200 stop rotating, they will return to the storage position under the action of the elastic force of the elastic reset member. Specifically, when the hiding fan is started, the fan blade 200 starts to rotate under the driving of the driver motor 820, and the centrifugal force of the fan blades 200 overcomes the elastic force of the elastic reset member, so that the fan blades 200 automatically stretch to the unfolded position; when the hiding fan is closed, the fan blades 200 stop rotating, the centrifugal force disappears, and the fan blades 200 are reset to the storage position under the action of the elastic force of the elastic reset member.
The example of the present disclosure also discloses a fan lamp, referring to
Optionally, the fan lamp includes a driver 710; the driver 710 is electrically connected to the motor assembly 800 through a first electrical connector, and the driver 710 is electrically connected to the lamp assembly 900 through a second electrical connector. The motor assembly 800 and the lamp assembly 900 for driving the fan blade 200 may be electrically connected with the same driver 710, so that the hiding fan and the lamp assembly 900 can be driven by the same one driver 710; compared with the way in which the hiding fan and the lamp assembly 900 are respectively driven by their respective drivers, the number of parts and components of the fan lamp disclosed in the examples of the present disclosure is reduced, so the fan lamp occupies a smaller space and, meanwhile, facilitates the transportation of the fan lamp.
In the example of the present disclosure, the motor assembly 800 includes a motor cover 810 and a driver motor 820 mounted in the motor cover 810; the motor cover 810 can protect the driver motor 820 and make the appearance of the fan lamp more beautiful. The driver motor 820 may be connected to the turntable 100 by transmission in any appropriate manner; in the examples of the present disclosure, the driver motor 820 is fixedly mounted on the annular installation seat 130, and the annular installation seat 130 has a central opening 110 in the middle to reduce the weight of the turntable 100 and avoid interference between the turntable 100 and the driver motor 820.
The specific structure of the lamp assembly 900 may be appropriately selected according to the usage requirements. Optionally, the lamp assembly 900 includes a lamp plate 910, a light source module 920 and a lamp shade 930.
