[0033] According to some embodiments of the present invention, a mounting bracket 132 is provided on the support component 13 , a slide groove 1321 extending along the pivot axis of the transmission part is formed in the mounting bracket 132 , and the support block 14 cooperates with the slide groove 1321 to limit the support block 14 from rotating relative to the transmission part.

[0034] like Figure 2 As shown, a mounting bracket 132 is provided on the support component 13, and a slide groove 1321 is formed in the mounting bracket 132. The support block 14 is movably arranged in the slide groove 1321. The extension direction of the slide groove 1321 is the same as the extension direction of the pivot shaft of the transmission part. The transmission part is accommodated in the slide groove 1321 and is threadedly matched with the support block 14. Due to the limitation of the slide groove 1321, the support block 14 will move along the extension direction of the slide groove 1321 under the drive of the transmission part. The inner wall of the slide groove 1321 stops against the edge of the support block 14 to prevent the support block 14 from flipping axially along the pivot shaft of the transmission part, thereby ensuring that the support surface angle on the support block 14 remains unchanged, so as to achieve stable support for the vehicle body.

[0035] According to some embodiments of the present invention, a flexible member 141 is disposed on the support block 14 , and a support surface is formed on the top surface of the flexible member 141 .

[0036] Specifically, a flexible member 141 is provided on the support block 14. The flexible member 141 can be configured as a nylon pad. A support surface is formed on the top surface of the nylon pad to support the bottom of the vehicle body.

[0037] According to some embodiments of the utility model, the supporting component 13 includes a supporting rod 133 and a telescopic arm 134, the supporting rod 133 is connected to the connecting arm 12, a positioning device 131 is provided on the supporting rod 133, and an installation channel extending in a first direction is formed inside the supporting rod 133; the telescopic arm 134 can be moved along the first direction and arranged in the installation channel, the mounting bracket 132 is arranged at one end of the telescopic arm 134, and the slide groove 1321 of the mounting bracket 132 extends in a second direction, and the second direction is orthogonal to the first direction.

[0038] like Figures 1 to 3 As shown, the support rod 133 is connected to the connecting arm 12 and extends along a first direction, which is the length direction of the vehicle body. An installation channel extending in the first direction is formed on the inner wall of the support rod 133. The telescopic arm 134 is movably arranged in the installation channel and moves along the first direction. When the vehicle body conveying hanger 1 moves to the designated station, the external power source cooperates with the telescopic arm 134 and can selectively drive the telescopic arm 134 to move along the installation channel to match the length dimension of the vehicle body; the mounting bracket 132 is arranged at one end of the telescopic arm 134. When the telescopic arm 134 is matched with the length dimension of the vehicle body, the external power source can push the support block 14 to move along the slide groove 1321 through the transmission part, wherein the slide groove 1321 extends along a second direction, which is the width direction of the vehicle body. By driving the support block 14 to move along the second direction to match the width dimension of the vehicle body, the telescopic arm 134 and the mounting bracket 132 are arranged to drive the support block 14 to match the length and width dimensions of the vehicle body, thereby realizing that the vehicle body conveying hanger 1 can carry a variety of vehicle models and improve production efficiency.

[0039] According to some embodiments of the present invention, a through hole 1322 communicating with the slide slot 1321 is formed on the mounting bracket 132 , and the through hole 1322 is coaxially arranged with the pivot axis of the transmission part to be suitable for connecting an external power source with the transmission part.

[0040] like Figure 2 As shown, a through hole 1322 connected to the slide groove 1321 is formed on the mounting bracket 132, and the transmission part can be embedded in the mounting bracket 132 through the bearing structure and the through hole 1322. The pivot shaft of the transmission part is coaxially arranged with the through hole 1322 to ensure smooth rotation of the transmission part. The driving shaft of the transmission part is exposed outside the through hole 1322. When the body conveying hanger 1 moves to the braking station along with the production line, the through hole 1322 can be directly opposite to the output end of the external power source, which is convenient for the output end to cooperate with the driving end and drive the transmission part to rotate.

[0041] According to some embodiments of the utility model, the vehicle body conveying hanger 1 also includes a first matching portion and a second matching portion, and the first matching portion and the second matching portion are respectively arranged on the support rod 133 and the telescopic arm 134, and the first matching portion and the second matching portion can selectively match and limit the relative movement of the telescopic arm 134 and the support rod 133 in the matching state.

[0042] Specifically, a first matching portion is provided on the telescopic arm 134, and a second matching portion is provided on the support rod 133. The first matching portion and the second matching portion can be selectively matched. When the first matching portion and the second matching portion are in a matched state, the telescopic arm 134 cannot move relative to the support rod 133. Specifically, when the current state of the vehicle body conveying hanger 1 does not match the vehicle model of the conveyed vehicle body, the telescopic rod needs to be moved to drive the support block 14 to match the vehicle model. At this time, the first matching portion and the second matching portion are released from the matched state, and the telescopic rod can move relative to the support rod 133. When the support block 14 is matched with the vehicle body size, the first matching portion and the second matching portion enter the matched state, and the telescopic arm 134 cannot move relative to the support rod 133, thereby ensuring that the position of the support block 14 remains unchanged and stably supports the vehicle body.

[0043] According to some embodiments of the utility model, the first matching portion is movably disposed on the support rod 133 to selectively approach or move away from the second matching portion, and a first locking tooth is formed on the surface of the first matching portion facing the second matching portion and is arranged in the first direction and extends in the second direction, and a second locking tooth is formed on the second matching portion and engages with the first locking tooth.

[0044] Specifically, the first matching portion can be selectively moved closer to or farther away from the second matching portion to achieve locking and unlocking of the first matching portion and the second matching portion, wherein when the first matching portion moves toward the second matching portion and engages the first locking tooth with the second locking tooth, the movement of the telescopic arm 134 in the first direction is restricted to ensure that the position of the support block 14 is stable; when the first matching portion moves away from the second matching portion and the matching state between the first matching portion and the second matching portion is released, the telescopic arm 134 can move along the first direction relative to the support rod 133 to drive the support block 14 to move and match the vehicle body size; after the matching is completed, the first matching portion and the second matching portion resume the matching state to ensure that the position of the support block 14 is stable.

[0045] According to some embodiments of the utility model, the first matching portion includes a base 1351, a clamping portion 1352 and an elastic member 1353, the base 1351 is arranged on the support rod 133, and a mounting shaft 1354 is arranged on the base 1351; the clamping portion 1352 is rotatably arranged on the mounting shaft 1354, and a first locking tooth is arranged on the clamping portion 1352; the elastic member 1353 is sleeved on the mounting shaft 1354 and is respectively connected to the base 1351 and the clamping portion 1352, and the elastic member 1353 is suitable for maintaining the locking of the first matching portion and the second matching portion.

[0046] like Figure 3 As shown, the base 1351 is arranged on the support rod 133, and a mounting shaft 1354 is arranged on the base 1351. The clamping portion 1352 can be rotatably arranged on the mounting shaft 1354. A connecting hole opposite to the base 1351 is formed on the support rod 133, and the first locking tooth on the clamping portion 1352 can be meshed with the second locking tooth through the connecting hole, wherein the elastic member 1353 is respectively matched with the base 1351 and the clamping portion 1352. In the absence of external force, the elastic member 1353 applies elastic force to the clamping portion 1352 and always keeps the first locking tooth meshed with the second locking tooth. The locking state of the first matching portion and the second matching portion is maintained by setting the elastic member 1353. The first matching portion has a simple structure, occupies a small space, and has a low maintenance cost.

[0047] According to some embodiments of the utility model, the connecting arm 12 is constructed in plurality, and each connecting arm 12 is provided with a supporting component 13. By providing a plurality of connecting arms 12 and supporting components 13 to support and fix the vehicle body, the transportation of the vehicle body is more stable, the vehicle body is prevented from falling during transportation, and the transportation of the vehicle body is safer.
