Detailed implementation manners

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with specific implementation manners. However, those skilled in the art should understand that the implementation manners described below are only used to illustrate the present invention and should not be regarded as limiting the scope of the present invention. All other implementation manners obtained by those of ordinary skill in the art based on the implementation manners in the present invention without creative efforts belong to the scope protected by the present invention.

[0023] As Figures 1-6 shown, the AGV double - vehicle linkage system 100 according to an embodiment of the present invention includes two vehicles 101 arranged in alignment front - to - back. The two vehicles 101 can carry objects together. The vehicle 101 includes a vehicle body 10, a hollow plate 20, an inclined block 30, and a cushion plate 40.

[0024] A plurality of first wheels 11 are provided below the vehicle body 10, and rectangular grooves 12 are provided on both sides of the vehicle body 10. A first cylinder 13 is installed inside the rectangular groove 12.

[0025] The hollow plate 20 is slidably arranged in the rectangular groove 12, and the hollow plate 20 is connected to the first cylinder 13. A second cylinder 21 is arranged along the length direction of the bottom of the hollow plate 20.

[0026] It should be noted that wireless transmission elements are also provided on the first cylinder 13 and the second cylinder 21 for wireless control of the first cylinder 13 and the second cylinder 21.

[0027] The side of the inclined block 30 is triangular. The inclined block 30 is slidably arranged in the hollow plate 20, and the higher end of the inclined block 30 is connected to the second cylinder 21.

[0028] The side of the backing plate 40 is triangular. The backing plate 40 is connected to the bottom of the hollow plate 20 through a return spring 41, and the backing plate 40 is arranged relatively parallel to the inclined surface of the inclined block 30. The second cylinder 21 can drive the inclined block 30 to move within the hollow plate 20, and the inclined block 30 gradually lifts the backing plate 40.

[0029] The beneficial effects of the AGV double - vehicle linkage system 100 proposed by the present invention are as follows:

[0030] When the width of the transported goods is greater than the width of the vehicle body 10, the first cylinder 13 extends the hollow plate 20 out of the rectangular groove 12 to increase the load - bearing width of the platform, which is beneficial to increasing the width of the vehicle body 10 through this operation. Then, the output end of the second cylinder 21 extends to drive the inclined block 30 to move. When the inclined block 30 moves, it will force the backing plate 40 to lift and stretch the return spring 41, facilitating the alignment of the backing plate 40 with the vehicle body 10. After alignment, it is convenient to distribute the weight of the goods. The return spring 41 facilitates the reset - down of the backing plate 40 when the inclined block 30 retracts.

[0031] In some embodiments, the inclination degrees of the inclined surfaces of the inclined block 30 and the backing plate 40 are the same.

[0032] In some embodiments, there are four return springs 41, and the four return springs 41 are arranged at the four corners of the backing plate 40.

[0033] In some embodiments, a plurality of first cylinders 13 are installed inside the rectangular groove 12, and the plurality of first cylinders 13 are all connected to the hollow plate 20.

[0034] In some embodiments, the AGV double - vehicle linkage system 100 further includes a disassembly and assembly mechanism 50 and a second wheel 60.

[0035] The disassembly and assembly mechanism 50 includes a hollow column 51, a rotating shaft 52, a disc 53, a plug 54, and a convex block 55. The rotating shaft 52 is arranged on the side of the vehicle body 10. The hollow column 51 is rotatably sleeved on the rotating shaft 52. A through - hole 551 is provided on the hollow column 51, and the through - hole 551 is connected to the inside of the hollow column 51. The plug 54 is inserted through the through - hole 551. The convex block 55 is arranged inside the hollow column 51 and is connected to the plug 54. The disc 53 is arranged on the rotating shaft 52, and an arc - shaped groove 531 is provided on the disc 53. The convex block 55 is installed in the arc - shaped groove 531.

[0036] A hollow groove 61 is provided through the second wheel 60, and a slot 62 is provided inside the hollow groove 61. The rotation of the disc 53 can drive the plug 54 to extend or retract into the inside of the hollow column 51, so that the hollow column 51 is inserted into the hollow groove 61, and the plug 54 is inserted into the slot 62.

[0037] It should be noted that the second wheel 60 being a solid wheel can enhance the load-carrying capacity. By increasing the number of wheels to share the pressure, the purpose of large load-carrying can be achieved. During actual operation, when it is necessary to increase the load capacity of the vehicle body 10, the second wheel 60 can be installed on the vehicle body 10 through the disassembly and assembly mechanism 50.

[0038] In some embodiments, four through holes 551 are provided along the circumferential surface of the hollow column 51, four arc-shaped grooves 531 are provided on the disc 53, there are four insertion blocks 54 and four convex blocks 55, and four slots 62 are provided along the circumferential surface inside the hollow groove 61.

[0039] In some embodiments, the number of the first wheels 11 and the second wheels 60 is the same, and the first wheels 11 and the second wheels 60 are alternately arranged.

[0040] In the present invention, the rotating shaft 52 drives the disc 53 to rotate counterclockwise. Since the convex block 55 is located inside the arc-shaped groove 531, when the disc 53 rotates counterclockwise, the four insertion blocks 54 are retracted into the inside of the hollow column 51. Then, the hollow groove 61 of the second wheel 60 is inserted outside the hollow column 51. After that, the disc 53 is rotated clockwise through the rotating shaft 52, and then the four insertion blocks 54 are extended and inserted into the inside of the slots 62, which is beneficial to fixing the second wheel 60 outside the hollow column 51 to realize the installation of the second wheel 60 to increase the load capacity, and the disassembly and assembly mechanism can quickly disassemble the old second wheel 60 for replacement.
