Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] A preferred embodiment of the fork anti-collision device for AGV forklift provided by the utility model is as follows: Figures 1 to 5 As shown: a fork anti-collision device for an AGV forklift, comprising a body 1, a control button 2 is fixedly connected to the top of the body 1, a control panel 3 located on the top of the body 1 is arranged at one end of the control button 2, a control panel 4 is slidably connected to the surface of the body 1, a fork frame 5 is fixedly connected to the surface of the control panel 4, blocks 7 are fixedly connected to both sides of the body 1, and protective mechanisms 6 are arranged on the sides of the two groups of blocks 7.

[0029] In this embodiment, the protection mechanism 6 includes a shielding component 61 and an alarm component 62. By providing the protection mechanism 6, the protection mechanism 6 can play a certain protective role on the fork frame 5 and the goods on the fork frame 5 to avoid being hit.

[0030] In this embodiment, the shielding assembly 61 includes a mounting plate 611, a connecting shaft 612, a connecting plate 613, a baffle 614 and a first spring 615. By setting the baffle 614, when a collision occurs, the baffle 614 will shield the fork frame 5 and collide with the obstacle itself. When a slight collision occurs, under the elastic force of the first spring 615, the baffle 614 will immediately rebound to its initial position after being hit, so that it will not cause a large impact on the fork frame 5 and cause the cargo to tip over.

[0031] In this embodiment, the mounting plate 611 is embedded in the interior of the block 7 and is located on one side of the vehicle body 1. The top and bottom of the mounting plate 611 are rotatably connected to the connecting shaft 612. The surfaces of the two sets of connecting shafts 612 are fixedly connected to the connecting plates 613. One end of the two sets of connecting plates 613 is fixedly connected to the baffle 614. One side of the baffle 614 is fixedly connected to the first spring 615 fixedly connected to the mounting plate 611.

[0032] In this embodiment, the alarm component 62 includes a push block 621, an alarm 622, an alarm button 623, a second spring 624, a push plate 625 and a force plate 626. By setting the alarm component 62, the alarm component 62 can remind people that the fork frame 5 has suffered a large impact and remind people to check in time.

[0033] In this embodiment, the push block 621 is fixedly connected to one side of the connecting plate 613, the alarm 622 is fixedly connected to one side of the mounting plate 611, an alarm button 623 is provided on one side of the alarm 622, a second spring 624 fixedly connected to the mounting plate 611 is provided on one side of the alarm 622, the tail of the second spring 624 is fixedly connected to a push plate 625 slidably connected to the mounting plate 611, and the top and bottom of the push plate 625 are fixedly connected to a force plate 626.

[0034] In this embodiment, the baffle 614 is a transparent plastic plate. The baffle 614 drives the connecting shaft 612 and the connecting plate 613 to form a rotating structure. The baffle 614 is transparent and will not block people from viewing the goods on the fork frame 5.

[0035] In this embodiment, the force plate 626 is located on the movement trajectory of the push block 621, and the push plate 625 forms a sliding structure through the force plate 626. When encountering a large impact, the baffle 614 will first drive the connecting plate 613 to rotate, and the push block 621 will rotate accordingly. When it rotates, it will push the force plate 626. When the force plate 626 is subjected to the thrust, it will drive the push plate 625 to move toward the alarm 622 on the surface of the mounting plate 611, and then press the alarm button 623 through the thrust.

[0036] Example 2

[0037] Based on Example 1, a preferred embodiment of a fork anti-collision device for an AGV forklift provided by the utility model is as follows: Figures 1 to 5 The mounting plate 611 is provided with a slot 8 inside, a third spring 9 is fixedly connected to the side of the vehicle body 1 , and a fixing plate 10 which is slidably connected to the vehicle body 1 and embedded in the slot 8 is fixedly connected to the tail of the third spring 9 .

[0038] In this embodiment, the slot 8 fits tightly with the surface of the fixing plate 10, and the mounting plate 611 forms a fixed structure inside the slot 8 through the fixing plate 10. The fixing plate 10 that is slidingly connected to the vehicle body 1 is pulled to the right to control the fixing plate 10 to move out of the slot 8. At this time, the mounting plate 611 loses the fixing force of the fixing plate 10 and can be pulled out from the inside of the card block 7.

[0039] The working principle and use process of the utility model are as follows: first, when the AGV forklift is working and transporting goods through the fork frame 5, in order to prevent the fork frame 5 from colliding with the goods or the wall during the driving process, causing the goods on the fork frame 5 to fall off, a baffle 614 is set. When a collision occurs, the baffle 614 will block the fork frame 5 and collide with the obstacle itself. When a slight collision occurs, under the elastic force of the first spring 615, the baffle 614 will immediately rebound to the initial position after being hit, so that it will not cause a large impact on the fork frame 5 and cause the goods to fall over.

[0040] When encountering a larger impact, the baffle 614 will first drive the connecting plate 613 to rotate, and the push block 621 will rotate accordingly. When it rotates, it will push the force-bearing plate 626. When the force-bearing plate 626 is pushed, it will drive the push plate 625 to move toward the alarm 622 on the surface of the mounting plate 611, and then press the alarm button 623 through the thrust. At this time, the alarm 622 will sound, thereby reminding the staff that the fork frame 5 has been subjected to a large impact force and to come to the scene to check in time.

[0041] When the protective mechanism 6 needs to be removed, the fixing plate 10 that is slidingly connected to the vehicle body 1 can be pulled to the right to control the fixing plate 10 to move out of the slot 8. At this time, the mounting plate 611 loses the fixing force of the fixing plate 10 and can be pulled out from the inside of the block 7, thereby achieving the purpose of quickly disassembling the protective mechanism 6.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
