Description

Technical Field

[0001] The utility model relates to the technical field of display equipment, in particular to a track magic wheel power transmission system. Background Art

[0002] The magic wheel is an industrial display item used for industrial product effect display or decoration; the magic wheel usually consists of five parts, including a rotating wheel, a rotating wheel driving mechanism, a surrounding coil, a surrounding coil driving mechanism and a supporting frame;

[0003] Referring to the prior art ZL2012100291510, the orbital magic wheel usually needs to be equipped with two drive motors, a reducer and a controller. Since the crankshaft used in the magic wheel product needs to reciprocate, the power transmission of the self-rotating drive motor located on the display wheel side of the orbital magic wheel becomes a difficulty.

[0004] Considering that the power transmission cable needs to be concealed to increase the magic effect, the power transmission cable of the self-rotating driving motor on one side of the display wheel in the magic wheel in the prior art adopts a spring cable, one end of which is directly connected to the power supply, power switch or controller through the mounting base after being connected to the motor.

[0005] However, during the operation of the magic wheel, since the surrounding coil moves around the display wheel, it is easy to frequently contact and rub the spring cable. The spring cable is also frequently stretched and contracted during the movement of the surrounding coil, which greatly reduces the service life of the spring cable. In addition, since the surrounding coil is also subjected to the elastic force exerted by the spring cable due to the recovery of the contracted state, the movement of the surrounding coil is blocked or interfered, resulting in an unsmooth movement trajectory, affecting the user's viewing experience.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 As shown, the utility model provides a track magic wheel power transmission system, comprising: a device body 1, a base 2, a crank device 3 and a cable 4; wherein the base 2 is arranged on one side of the device body 1; the crank device 3 is arranged on the base 2; the crank device 3 is transmission-connected with the device body 1; the cable 4 is connected to the device body 1 along the crank structure. This solution connects the cable 4 with the crank structure, wherein the cable 4 is arranged along the surface of the crank structure and moves synchronously with the movement of the crank structure, thereby avoiding collision between the cable 4 and the surrounding coil during the display process, preventing the cable 4 from interfering with the surrounding coil, and ensuring the display effect.

[0038] It should be noted that the magic wheel is an industrial display item, used for displaying or decorating industrial product effects; the magic wheel usually consists of five parts, including a rotating wheel, a rotating wheel drive mechanism, a surrounding coil, a surrounding coil drive mechanism and a support frame; referring to the prior art, a track magic wheel usually needs to be equipped with two drive motors, a reducer and a controller. Since the crankshaft used in the magic wheel product needs to reciprocate, the power transmission of the self-rotating drive motor located on the display wheel side of the track magic wheel becomes a difficult point.

[0039] Considering that the power transmission cable needs to be concealed to increase the magic effect, the power transmission cable of the self-rotating driving motor on one side of the display wheel in the magic wheel in the prior art adopts a spring cable, one end of which is directly connected to the power supply, power switch or controller through the mounting base after being connected to the motor.

[0040] It should be noted that the center hole of the bearing 5 is designed to be substantially the same size as that of the cable 4 , so that the cable 4 can be snap-fitted with the center hole of the bearing 5 , ensuring that the bearing 5 can drive the cable 4 to rotate synchronously.

[0041] It should be noted that the device body 1 includes a display wheel and a display wheel shaft rotatably connected to the display wheel; and a surrounding coil and a surrounding coil driving mechanism matched with the display wheel. The display wheel is connected to the display wheel shaft, and the display wheel shaft is used to drive the display wheel to rotate. The surrounding coil driving mechanism is connected to the surrounding coil and is used to drive the surrounding coil to move around the display wheel.

[0042] It should be noted that the end of the cable 4 away from the device body 1 is connected to structures such as a power supply and a switch controller.

[0043] In this solution, the cable 4 starts from the power supply, extends to the base 2 and passes through the center hole of the bearing 5 and enters the second channel. The cable 4 passes through the second channel and is arranged on the surface of the second crank arm 323. The cable 4 enters the first channel and passes through the first channel. The cable 4 passes through the first channel and is arranged on the surface of the first crank arm 321, and is connected to the device body 1 along the surface of the first crank arm 321.

[0044] In this embodiment, the first crank arm 321 and the second crank arm 323 are arranged in parallel with each other.

[0045] Furthermore, the crank device 3 includes a crank driving structure 31 and a crank transmission structure 32. The crank driving structure 31 is fixed on the base 2, and the crank transmission structure 32 is arranged between the crank driving structure 31 and the device body 1; the crank transmission structure 32 includes a first crank arm 321 and a crank and a second crank arm 323. One end of the first crank arm 321 is connected to the first end of the crank neck 322, and the other end of the first crank arm 321 is connected to the device body 1; one end of the second crank arm 323 is connected to the second end of the crank neck 322, and the other end of the second crank arm 323 is connected to the crank driving structure 31. In the actual moving process, the first crank arm 321 is fixedly connected to the device body 1, and the second crank arm 323 is fixedly connected to the crank driving structure 31, so that the crank neck 322 can swing around the center of the display wheel. It should be noted that the first crank arm 321 and the second crank arm 323 rotate synchronously to ensure the overall stability.

[0046] It should be noted that the first crank arm 321 is fixedly connected to the display wheel shaft.

[0047] Specifically, the curved neck 322 in this embodiment is cylindrical, and a through hole is provided inside the curved neck 322 along the axial direction to form a first channel suitable for the cable 4 to pass through. The cable 4 enters the first channel along the surface of the first crank arm 321, and passes through the first channel and is further arranged on the surface of the second crank arm 323. It should be noted that the cable 4 is fixed to the surfaces of the first crank arm 321 and the second crank arm 323 by bonding or wire staples.

[0048] Furthermore, the crank drive structure 31 includes a drive motor 311 and a crank shaft 312, and the drive motor 311 is a servo motor in this solution. The crank shaft 312 is connected to the drive motor 311; the crank shaft 312 is provided with a through hole along the axial direction to form a second channel suitable for the cable 4 to pass through; the crank shaft 312 is connected to the end of the second crank arm 323 away from the crank neck 322; the cable 4 is arranged in the second channel. In this solution, the cable 4 passes through the second channel, the surface of the second crank arm 323, the first channel, the surface of the first crank arm 321 and is connected to the device body 1 in sequence. The arrangement of the cable 4 through the inside of the device prevents the cable 4 from interfering with the movement of the surrounding coil.

[0049] It should be noted that the crank shaft 312 is fixedly connected to the second crank arm 323 and drives the second crank arm 323 to rotate. The second crank arm 323 drives the first crank arm 321 to rotate through the crank neck 322 .

[0050] like Figure 2As shown, it should be noted that the crank shaft 312 and the drive motor 311 are driven by gears, and a first gear is provided at the output end of the drive motor 311. A second gear is provided at the end of the crank shaft 312 close to the output end of the drive motor 311, and the drive motor 311 drives the drive shaft to rotate through the meshing of the first gear and the second gear. The drive shaft is fixedly connected to the second crank arm 323, driving the second crank arm 323 to rotate.

[0051] Furthermore, bearings 5 ​​are provided at both ends of the crank shaft 312, and the bearings 5 ​​are arranged to rotate relative to the crank shaft 312, and the center hole of the bearing 5 is connected to the second channel. The cable 4 is suitable for passing through the center hole of the bearing 5, and the cable 4 rotates synchronously with the bearing 5. Passing the cable 4 through the bearing 5 can avoid the rotation of the cable 4 during the display process due to the crank transmission process, thereby causing the rotation of the cable 4 to be different from the rotation speed of the crank shaft 312, and the cable 4 and the crank shaft 312 to move relative to each other and generate friction, causing the cable 4 to be easily damaged. In this solution, the cable 4 is fixed to the bearing 5, thereby avoiding the friction between the cable 4 and the crank shaft 312, and increasing the service life of the cable 4.

[0052] It should be noted that, in the present embodiment, both ends of the crank shaft 312 are fixed to the base 2 via bearings 5; as an alternative implementation, the crank shaft 312 may also be fixed to the base 2 via bolts.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
