[0007] Furthermore, the connection mechanism also includes a lifting block and a lifting spring, wherein the lifting spring is fixed at the bottom of the card slot, the lifting block is fixed at the top of the lifting spring, and the lifting block is located below the card block.

[0008] Furthermore, the upper end surface of the clamping block and the lower end surface of the inserting block are both arc surfaces.

[0009] Furthermore, the pull rod, the clamping block, the limit spring and the receiving groove are each provided with two, and the receiving groove is located on both sides of the upper groove.

[0010] Furthermore, a pull plate is fixed to one end of the pull rod located outside the fixing block.

[0011] Furthermore, it also includes a steering mechanism, which includes a driving motor, a first bevel gear, a second bevel gear, a swivel, an electric push rod and a lifting plate. A lower slot is provided at the lower part of the trolley body, and a mounting slot is provided on the side of the lower slot. The driving motor is installed in the mounting slot, the first bevel gear is fixedly connected to the output shaft of the driving motor, the swivel is rotatably connected to the top of the lower slot, the electric push rod is fixedly connected to the swivel, and the output end of the electric push rod is vertically downward, the second bevel gear is fixed to the outside of the electric push rod, and the second bevel gear is meshed with the first bevel gear, the lifting plate is fixed to the bottom of the electric push rod, and the stroke of the electric push rod can drive the lifting plate to extend out of the lower slot and against the ground.

[0012] Furthermore, the steering mechanism also includes a positioning plate, which is fixed to a side of the mounting groove, and the output shaft of the driving motor passes through the positioning plate and is rotationally connected to the positioning plate.

[0013] The beneficial effects of this solution are as follows: (1) The lifting plate can be installed and fixed by limiting the insertion block by the card block.

[0016] (4) The electric push rod in the steering mechanism pushes the lifting plate against the ground, starting the drive motor, which drives the first bevel gear to rotate. Due to the friction between the lifting plate and the ground, the lifting plate can be stationary relative to the ground. At this time, the drive motor drives the first bevel gear to rotate, causing the first bevel gear to move around the second bevel gear, thereby driving the main body of the trolley to rotate and realize the steering of the main body of the trolley. After the steering is completed, the drive motor is turned off and the electric push rod is retracted, so that the lifting plate is retracted into the lower slot, and the main body of the trolley resumes normal driving, realizing the automatic steering of the latent lifting AGV.

[0024] Combination Figure 3 As shown, the connecting mechanism 4 includes a fixed block 5, two pull rods 6, two clamping blocks 7, two limit springs 8, a lifting block 9 and a lifting spring 10. The fixed block 5 is fixed at the top of the lifting mechanism 3. A clamping slot is provided on the upper part of the fixed block 5. Two receiving slots and through holes are provided on both sides of the clamping slot. The two clamping blocks 7 are respectively fixed at one end of the two pull rods 6, and the clamping blocks 7 are located in the clamping slots. The two pull rods 6 pass through the receiving slots and the through holes respectively and extend out of the fixed block 5. A pull plate is fixed at one end of the pull rod 6 located outside the fixed block 5. The two limit springs 8 are respectively sleeved on the two pull rods 6. The limit spring 8 is located in the receiving slot. An insertion block 11 is provided at the bottom of the lifting plate 2. The two clamping blocks 7 extend out of the receiving slot and can be inserted into the insertion block 11. The upper end surface of the clamping block 7 and the lower end surface of the insertion block 11 are both arc surfaces.

[0025] Specific as Figure 2 As shown, the steering mechanism includes a driving motor 12, a positioning plate 13, a first bevel gear 14, a second bevel gear 15, a swivel 16, an electric push rod 17 and a lifting plate 18. A lower slot is provided at the lower part of the trolley body 1, and a mounting slot is provided on the side of the lower slot. The driving motor 12 is installed in the mounting slot, the positioning plate 13 is fixed on the side of the mounting slot, the output shaft of the driving motor 12 passes through the positioning plate 13 and is rotatably connected to the positioning plate 13, the first bevel gear 14 is fixedly connected to the output shaft of the driving motor 12, the swivel 16 is rotatably connected to the top of the lower slot, the electric push rod 17 is fixedly connected to the swivel 16, and the output end of the electric push rod 17 is vertically downward, the second bevel gear 15 is fixed on the outside of the electric push rod 17, and the second bevel gear 15 is meshed with the first bevel gear 14, the lifting plate 18 is fixed at the bottom of the electric push rod 17, and the stroke of the electric push rod 17 can drive the lifting plate 18 to extend out of the lower slot and abut against the ground.

[0026] The specific implementation process is as follows: during operation, the upper end surface of the clamping block 7 and the lower end surface of the insertion block 11 are both curved surfaces. When installing the jacking plate 2, the insertion block 11 is directly placed in the clamping slot and pressed down. The insertion block 11 is against the curved surface of the clamping block 7, thereby squeezing the clamping block 7 to move to both sides. When the insertion block 11 is inserted and installed, the limit spring 8 drives the pull rod 6 and the clamping block 7 to return to their original position, clamping the upper end surface of the insertion block 11 to complete the fixation, and the installation is fast. The restriction of the clamping block 7 on the insertion block 11 can realize the installation and fixation of the jacking plate 2.

[0027] The electric push rod 17 in the steering mechanism pushes the lifting plate 18 to contact the ground, starting the drive motor 12, and the drive motor 12 drives the first bevel gear 14 to rotate. Due to the friction between the lifting plate 18 and the ground, the lifting plate 18 can be stationary relative to the ground. At this time, the drive motor 12 drives the first bevel gear 14 to rotate, so that the first bevel gear 14 moves around the second bevel gear 15, thereby driving the trolley body 1 to rotate to achieve the steering of the trolley body 1. After the steering is completed, the drive motor 12 is turned off, and the electric push rod 17 is retracted, so that the lifting plate 18 is retracted into the lower slot, and the trolley body 1 resumes normal driving, realizing the automatic steering of the latent lifting AGV.
