Detailed Description of the Embodiments

[0027] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the illustrated embodiments are not intended to limit the present utility model.

[0028] Referring to Figure 1-4 As shown, the simple battery pack transfer trolley of the present utility model includes: a trolley body 1, the material of the frame of which is aluminum profile. A caster 11 is connected to the lower end of the trolley body 1, and a table board 12 is provided on the upper end surface of the trolley body 1. A tabletop anti-static pad 13 is laid on the table board 12, and the tabletop anti-static pad 13 is used for electrostatic isolation between the article and the table board 12; a traction mechanism 2, which is arranged on the trolley body 1. The traction mechanism 2 includes a fixed seat 21, a forward insert 22, a non-return stop 23, a spring 24 and a hinge pin 25. The fixed seat 21 is fixedly connected to the trolley body 1. The forward insert 22 is arranged on the fixed seat 21. The non-return stops 23 are two symmetrically arranged, and the springs 24 are two symmetrically arranged. The non-return stops 23 are connected to the fixed seat 21 through the hinge pin 25, and the springs 24 are arranged between the non-return stops 23 and the fixed seat 21. A connection groove 221 for accommodating the traction shaft of the AGV trolley is provided on the forward insert 22.

[0029] The profile frame is the skeleton of the trolley body. The table board 12 is installed on the profile frame, and the tabletop anti-static pad 13 is above it. The function of the tabletop anti-static pad 13 is to prevent the article from directly contacting the table board and generating static electricity due to relative sliding.

[0030] In the above structure, the forward insert 22 is arranged in a semi-circular shape, the connection groove 221 is semi-circular, and the connection groove 221 is arranged on the end surface of the forward insert 22 opposite to the non-return stop 23. The fixed seat 21 is in a rectangular block shape, and a U-shaped groove 211 is provided at the end of the fixed seat 21 opposite to the moving direction of the transfer trolley. The forward insert 22 is arranged at the bottom of the U-shaped groove 211.

[0031] In the above structure, limiting bosses 212 are provided on the opposite inner walls of the U-shaped groove 211. The limiting bosses 212 are used to limit the forward insert block 22 within the bottom of the U-shaped groove 211. The end of the limiting boss 212 away from the U-shaped groove 211 extends to the end position of the connecting groove 221, and the limiting boss 212 is arranged not to protrude into the opening range of the connecting groove 221, so that the traction shaft of the AGV vehicle can smoothly enter the connecting groove 221, and at the same time, it can be avoided that the traction shaft of the AGV vehicle is stuck by the limiting boss 212 when it is released from the connecting groove 221. Steps 213 are provided on the opposite inner walls of the U-shaped groove 211. The hinge pin 25 is arranged on the step 213. The middle position of the anti-retreat stop block 23 is connected to the hinge pin 25. The two ends of the spring 24 are respectively connected to the inner wall of the U-shaped groove 211 and one end of the anti-retreat stop block 23 close to the forward insert block 22. An anti-retreat cushion block 231 is provided at one end of the anti-retreat stop block 23 close to the forward insert block 22. By providing the anti-retreat cushion block 231, it can be avoided that the anti-retreat stop block 23 is in hard contact with the traction shaft of the AGV vehicle, causing damage to the traction shaft of the AGV vehicle. The spring 24 provides an elastic force, so that one end of the anti-retreat stop block 23 connected to the spring 24 is away from the inner wall of the U-shaped groove 211, and the gap between the ends of the two anti-retreat stop blocks 23 close to each other is smaller than the width of the opening of the connecting groove 221, and the gap between the ends of the two anti-retreat stop blocks 23 away from each other is larger than the diameter of the traction shaft of the AGV vehicle. After the traction shaft of the AGV vehicle enters the connecting groove 221, the traction shaft of the AGV vehicle can be limited within the connecting groove 221 by the two anti-retreat stop blocks 23.

[0032] The working principle of the traction mechanism 2 is as follows:

[0033] The AGV vehicle 100 is docked with the vehicle body 1. The traction shaft 101 of the AGV vehicle is in the extended state. The AGV vehicle 100 enters below the vehicle body 1 from the back of the vehicle body 1. The anti-thrust stop block 23 of the traction mechanism 2 of the vehicle body 1 is in the open state at the tail under the action of the spring force of the spring 24. When the traction shaft 101 of the AGV vehicle 100 enters between the two anti-thrust stop blocks 23, it squeezes the anti-thrust stop block 23 and overcomes the spring force of the spring 24 to enter the connecting groove 221. At this time, the docking of the AGV vehicle 100 and the vehicle body 1 is completed. The AGV vehicle 100 moves forward, and its traction shaft 101 pushes the traction mechanism (at this time, the forward insert block is stressed), driving the entire vehicle body 1 to move forward. When the AGV vehicle 100 decelerates, at this time, under the action of inertia, the speed of the vehicle body 1 will be faster than that of the AGV vehicle 100, resulting in the traction shaft 101 of the AGV canceling the thrust on the traction mechanism and generating a blocking force on the anti-thrust stop block 23 (at this time, the anti-retreat cushion block is stressed), causing the AGV vehicle to decelerate until the AGV vehicle completely stops, and then the vehicle body 1 also completely stops.

[0034] In the above structure, the cross-section of the tabletop 12 is rectangular. A number of cushion blocks 121 are provided on the tabletop 12, and the ends of the cushion blocks 121 penetrate through the anti-static mat. Limit blocks 122 are provided at the four corner positions of the tabletop 12. The limit blocks 122 are in a right-angled shape, and the height of the limit blocks 122 is greater than the height of the cushion blocks 121.

[0035] The trolley body 1 is a rectangular frame, and a caster mounting seat is installed at each of the four corners of the lower end of the trolley body 1. A caster 11 is installed below each caster mounting seat, and a caster protection frame is installed on each set of casters 11. The function of the caster protection frame is to prevent the wheels from pressing on people's feet during the operation of the trolley.

[0036] In the above structure, a tool box one 14 and a tool box two 15 are provided on the trolley body 1. The tool box one 14 and the tool box two 15 are both rectangular box-shaped. An anti-static mat one 141 is provided on the bottom surface of the tool box one 14, and an anti-static mat two 151 is provided on the bottom surface of the tool box two 15. The tool box one 14 and the tool box two 15 are of different sizes, and the tool box one 14 and the tool box two 15 are used to store tools. The function of laying the anti-static mat one 141 and the anti-static mat two 151 is to prevent static electricity from being generated by the direct friction between the tools and the tool boxes.

[0037] In the above structure, an electrostatic discharge chain 16 is connected to the trolley body 1, and the electrostatic discharge chain 16 is used to discharge the static electricity of the trolley body 1.

[0038] Refer to Figure 5 、 6As shown in the figure, handle assemblies 3 are provided on both the front and rear sides in the traveling direction of the trolley body 1, and the handle assemblies 3 are used to push and pull the trolley body 1. The handle assembly 3 includes a handle body 31, a handle hinge pin 32, a hinge seat 33, an L-shaped pin 34, a handle buffer pad 35, a fixing ring 36, a handle spring 37, and a pin fixing seat 38. The hinge seat 33 is fixedly connected to the trolley body 1. There are two hinge seats 33, and there are two handle hinge pins 32. Both ends of the handle body 31 are connected to the hinge seats 33 through the handle hinge pins 32. The handle buffer pad 35 is arranged on the hinge seat 33, and the handle buffer pad 35 is located on the end face of the hinge seat 33 in contact with the handle body 31. The handle buffer pad 35 is used to buffer the contact force between the handle body 31 and the hinge seat 33. The pin fixing seat 38 is fixedly connected to the trolley body 1. The long end of the L-shaped pin 34 penetrates through the pin fixing seat 38 and the hinge seat 33 close to the pin fixing seat 38. The fixing ring 36 is fixedly connected to the outer wall of the long end of the L-shaped pin 34, and the fixing ring 36 is located between the pin fixing seat 38 and the hinge seat 33 close to the pin fixing seat 38. The handle spring 37 is sleeved on the long end of the L-shaped pin 34, and the handle spring 37 is located between the pin fixing seat 38 and the fixing ring 36. A first pin hole 381 is provided on the pin fixing seat 38, and a second pin hole 331 and a third pin hole 332 are provided on the hinge seat 33. The part of the L-shaped pin 34 inserted between the second pin hole 331 and the third pin hole 332 can lock the handle body 31.

[0039] The working principle of the handle assembly 3 is as follows:

[0040] The handle body 31 is the main body of the handle assembly. One handle hinge pin 32 is inserted at each end of it. The handle hinge pin 32 is installed in the hinge seat 33. When the L-shaped pin 34 is opened, the handle body 31 can rotate around the hinge pin. A handle buffer pad 35 is installed on the inner side of the hinge seat 33 to buffer the handle body 31. The L-shaped pin 34 is inside the pin fixing seat 38, and the other end can be inserted into the handle hinge pin 32. A fixing ring 36 is installed at one end of the L-shaped pin 34 close to the handle hinge pin 32. A handle spring 37 is provided between the fixing ring 36 and the pin fixing seat 38. The handle spring 37 is compressed by the pin fixing seat 38 and the fixing ring 36, so that the L-shaped pin 34 is inserted into the handle hinge pin 32. At this time, the handle is limited by the L-shaped pin 34 and cannot rotate around the handle hinge pin 32. When the L-shaped pin 34 is pulled out of the handle hinge pin 32, the handle spring 37 is further compressed. At this time, the handle body 31 can rotate around the handle hinge pin 32. When the external pulling force on the L-shaped pin 34 is withdrawn, the handle spring 37 resumes, and the L-shaped pin 34 is inserted into the handle hinge pin 32 again. At this time, the rotation of the handle body 31 is restricted again.

[0041] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill 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 enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of this utility model.
