[0029] See also Figure 1-3 , Figure 5 The present invention provides a technical solution: a carrier, comprising a carrier frame 1, the upper end of which is sequentially provided with a first front support 2, a second front support 3, a first flip support 4, a first rear support 5, a second flip support 6 and a second rear support 7;

[0030] The upper ends of the first front support 2, the second front support 3, the first flip bracket 4 and the second flip bracket 6 are all provided with locking components 8 for matching with corresponding holes at the lower end of the vehicle body;

[0031] The first front support 2 and the second front support 3 have the same structure, the height of the first front support 2 is higher than the second front support 3, and the lower ends of the first front support 2 and the second front support 3 are fixed on the carrier frame 1;

[0032] The upper end of the first rear support 5 is a square tube 51, and both sides of the upper end of the second rear support 7 are brackets 71. The lower ends of the first rear support 5 and the second rear support 7 are fixed on the carrier frame 1;

[0033] The first flip bracket 4 and the second flip bracket 6 can both be flipped 90° on the carrier frame 1. The two have the same structure, and when installed, the flip directions of the first flip bracket 4 and the second flip bracket 6 are opposite.

[0034] The locking assembly 8 includes a connecting rod 81, a supporting block 82, a vertical block 83, a rotating shaft 84, a locking pin 85, a rotating block 87 and a top block 88. The two ends of the connecting rod 81 are symmetrically provided with supporting blocks 82, the upper end of the supporting block 82 is fixed with a vertical block 83, the supporting block 82 is rotatably connected with a rotating shaft 84, the upper end of the rotating shaft 84 is provided with a locking pin 85, the locking pin 85 matches the hole size of the lower end of the vehicle body, the central axis of the locking pin 85 does not coincide with the central axis of the rotating shaft 84, the upper end of the locking pin 85 passes through the top block 88, the top block 88 is fixed to the upper end of the vertical block 83, the lower end of the rotating shaft 84 passes through the supporting block 82 and is fixedly connected to the rotating block 87, through the eccentric setting of the locking pin 85 and the rotating shaft 84, by driving the rotating block 87 to rotate, the locking pin 85 rotates and corresponds to the hole at the lower end of the vehicle body, thereby supporting the vehicle body;

[0035] The first flip bracket 4 includes a rotating rod 401, a base 402, a fixed block 403, a screw 404, a connecting block 405 and a connecting shaft 406. The rotating rod 401 is symmetrically arranged at the lower end of the connecting rod 81. The base 402 is arranged below the rotating rod 401. The base 402 is fixedly connected to the carrier frame 1. The fixed block 403 is symmetrically arranged with the upper end of the base 402. The rotating rod 401 is located between the two fixed blocks 403. The screw 404 is inserted between the two fixed blocks 403 and the rotating rod 401. The rotating rod 401 and the screw 404 rotate between the two fixed blocks 403. One end of the screw 404 is threadedly connected with a nut, and the other end of the screw 404 is connected to the connecting block 405. The upper end of the connecting block 405 is connected to the rotating rod 401 through the connecting shaft 406. By driving the connecting block 405 to rotate, the screw 404 is driven to rotate, thereby driving the locking assembly 8 to flip.

[0036] Furthermore, in order to prevent the rotating shaft 84 from always rotating along the central axis of the rotating shaft 84 during rotation and avoid lateral jumping, third spring plates 86 are symmetrically arranged on both sides of the vertical block 83, and the third spring plates 86 are in contact with the outer side surface of the rotating shaft 84.

[0038] Furthermore, in order to ensure that the locking assembly 8 remains in a vertical state after the first flip bracket 4 and the second flip bracket 6 are flipped, a clamping block 414 is connected to one end between the two fixed blocks 403, and the internal thread of the clamping block 414 is connected to a limiting screw 415. The position of the limiting screw 415 is adjusted, and the rotating rod 401 rotates 90° to just contact the end of the limiting screw 415 to prevent it from rotating too much.

[0039] Furthermore, in order to ensure that the first flip bracket 4 and the second flip bracket 6 will not flip back after being rotated and erected, a first spring plate 407 is provided on one side of the fixed block 403 corresponding to one of the rotating rods 401, and a clamping pin 408 is tightly attached to one side of the first spring plate 407. The clamping pin 408 is fixed to the outer side surface of the screw 404. The friction force generated by the clamping pin 408 clamping the first spring plate 407 can prevent rotation after rotation.

[0040] A method for a carrier to realize co-line transportation of different vehicle types:

[0041] When the detection system detects that the vehicle type is a small vehicle type, only one of the above-mentioned carriers is needed. For a vehicle type with a low skirt, the first front support 2 and the second rear support 7 are selected to carry the front and rear ends of the vehicle body respectively;

[0042] For models with high skirts, the second front support 3 and the second rear support 7 are selected to carry the front and rear ends of the vehicle body respectively;

[0043] When the detection system detects that the vehicle type is a cargo box vehicle type, two of the above-mentioned carriers are required to be used. The front end of the vehicle body of the carrier located in the front position is mounted on the first rear support 5, and the rear end of the vehicle body is mounted on the first flip support 4 and the second flip support 6 located on the rear carrier. At this time, the first flip support 4 and the second flip support 6 are in an upright state.

[0044] When the vehicle body is loaded, after the transplanter moves the vehicle body into position, the toggle mechanism drives the transfer block 87 of the locking assembly 8 of the first front support 2 or the second front support 3 or the first flip support 4 or the second flip support 6 to rotate, so that the locking pin 85 is fixed to the hole position at the lower end of the vehicle body;

[0045] The erection process of the first flip support 4 and the second flip support 6 is as follows: the toggle mechanism located at the side of the conveyor line controls the connecting block 405 to rotate 90° to erect the locking assembly 8 at its upper end, thereby achieving the loading of the vehicle body.

[0046] Example 2: Figure 4 , which is different from Example 1, is that a special-shaped block 410 is fixed at the lower end of another rotating rod 401, and the special-shaped block 410 is fixed to the outer side of the screw rod 404. The special-shaped block 410 is provided with two through holes, and the two through holes are arranged at 90°. A fixing plate 412 is provided on one side of the fixing block 403 corresponding to the rotating rod 401, and an oblong countersunk hole 413 is provided on the fixing plate 412. An elbow pin 411 passes through the special-shaped block 410 and the two fixing blocks 403, and the elbow part of the elbow pin 411 is located in the oblong countersunk hole 413. When the toggle mechanism driving the first flip support 4 and the second flip support 6 fails, the elbow pin 411 is pulled out, and the manual flip locking assembly 8 is erected. At this time, the special-shaped block 410 is rotated 90°, and then the elbow pin 411 is inserted to realize manual control of the erection of the first flip support 4 and the second flip support 6.

[0047] The present invention can select and match different supports or brackets according to different vehicle models, thereby realizing the co-production of multiple vehicle models, avoiding interference, being free from space restrictions, and greatly improving the convenience of use.
