[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The utility model provides Figure 1-3 The automatic protection mechanism of an AGV trolley shown in the figure includes an automatic trolley 1, a protection component 2 is provided on the front of the automatic trolley 1, and the protection component 2 includes a protection shell 21, an integrated frame 22, a connecting plate 23, a universal wheel 24 and an electric cylinder 25. The protection shell 21 is fixedly connected to the front of the automatic trolley 1, and the integrated frame 22 is installed inside the protection shell 21. The protection shell 21 and the integrated frame 22 can provide anti-collision protection for the automatic trolley 1. The connecting plate 23 is slidably provided inside the protection shell 21, and the universal wheel 24 is installed on the connecting plate 23. At the bottom of the plate 23, the electric cylinder 25 is installed inside the protective shell 21 through the integrated frame 22. The output end of the electric cylinder 25 is transmission-connected to the connecting plate 23. When the automatic trolley 1 goes downhill or brakes suddenly, the power supply inside the automatic trolley 1 can provide power for the electric cylinder 25. The electric cylinder 25 drives the connecting plate 23 to descend, so that the universal wheel 24 at the bottom of the connecting plate 23 contacts the ground, thereby supporting the front end of the automatic trolley 1, thereby reducing the situation where the automatic trolley 1 tilts forward when the automatic trolley 1 goes downhill or brakes suddenly.

[0031] In particular, the integrated frame 22 includes a mounting plate 221, a locking assembly 224, a mounting frame 222 and a guide rod 223. The mounting plate 221 is installed on the top of the inner cavity of the protective shell 21 through the locking assembly 224. The end of the guide rod 223 is fixedly connected to the mounting frame 222 and the mounting plate 221, and the mounting plate 221 and the mounting frame 222 can improve the stability of the overall shape of the protective shell 21. The top of the inner wall of the protective shell 21 is fixedly connected with a card block 225, and the top of the mounting plate 221 is provided with a card slot matching the card block 225. The mounting frame 222 is sleeved on the bottom of the inner cavity of the protective shell 21. The card block 225 can improve the stability of the mounting plate 221 installed inside the protective shell 21. The outer wall of the guide rod 223 is slidably inserted and sleeved with the connecting plate 23, and the guide rod 223 can improve the stability of the connecting plate 23 moving up and down inside the protective shell 21.

[0032] Furthermore, the locking assembly 224 includes a fixed shaft 2241 and a locking plate 2242. The top of the fixed shaft 2241 is fixedly connected to the top of the inner wall of the protective shell 21. The locking plate 2242 is rotatably sleeved on the outside of the fixed shaft 2241. The locking plate 2242 is clamped on the bottom of the mounting plate 221. The top of the mounting plate 221 is symmetrically provided with connecting holes that match the locking plate 2242, and the size of the connecting hole is larger than the size of the locking plate 2242. Therefore, when the locking plate 2242 and the connecting hole are cross-staggered, the locking plate 2242 can be located at the bottom of the mounting plate 221 to lock the mounting plate 221. The bottom of the connecting plate 23 is symmetrically provided with circular holes corresponding to the locking plate 2242. Therefore, under the action of the circular holes, the connecting plate 23 moves up and down without contacting the locking assembly 224.

[0033] Furthermore, the locking assembly 224 also includes a connecting frame 2243 and a positioning rod 2244. The connecting frame 2243 is slidably inserted and sleeved on the outside of the fixed shaft 2241. The bottom of the positioning rod 2244 is fixedly connected to the connecting frame 2243. The outer wall of the positioning rod 2244 is slidably inserted and sleeved with the locking plate 2242. The bottom of the mounting plate 221 is provided with a positioning groove that matches the positioning rod 2244. When the positioning rod 2244 at the top of the connecting frame 2243 is engaged with the locking plate 2242 and the mounting plate 221, the locking plate 2242 can be limited to keep the locking plate 2242 stable with the connecting hole. When the fixing shaft 2241 is in a fixed cross-staggered state and the locking state between the positioning rod 2244 and the mounting plate 221 is released so that the locking plate 2242 coincides with the connecting hole, the mounting plate 221 inside the protective shell 21 can be disassembled, and the bottom of the fixed shaft 2241 is fixedly connected to the limiting block 2245, and the outer wall of the fixed shaft 2241 is slidably sleeved with a support spring 2246, which is located between the limiting block 2245 and the connecting frame 2243. The support spring 2246 can support the connecting frame 2243, so that the positioning rod 2244 is in a stable state and is locked with the locking plate 2242 and the mounting plate 221.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
