The embodiment of the first aspect of the invention provides an AGV automatic locking mechanism, which comprises a locking member 1, a connecting seat 2, a jaw assembly 3 and a resetting assembly 4, wherein the locking member 1 is arranged on the connecting seat 2; the jaw assembly 3 is rotatably connected with the connecting seat 2, a reset assembly 4 is arranged between the jaw assembly 3 and the connecting seat 2, the reset assembly 4 is used for applying acting force to the jaw assembly 3 so that the jaw assembly 3 is reset to form a locking groove 5 for locking the locking part 1, and the locking groove 5 is provided with an inlet and an outlet; the locking piece 1 is used for being connected with the AGV, and the locking piece 1 can overcome the acting force of the reset assembly 4 and enter the locking groove 5 from the inlet and the outlet; the connecting seat 2 is used for being connected with a skip car.

As shown in figure 1, when assembling the automatic locking mechanism of AGV, at first aim at retaining member 1 with the business turn over mouth department of locking groove, continue propelling movement retaining member 1 afterwards, retaining member 1 overcomes reset assembly 4's effort for jaw assembly 3 rotates for the connecting seat, and the mouth opening increase is imported and exported, and retaining member 1 gets into the locking groove smoothly, and then under reset assembly 4's effort, jaw assembly 3 resets, and locking groove 5 locks the retaining member.

Among the automatic locking mechanism of above-mentioned AGV, jaw assembly 3 can automatic locking retaining member 1 under reset assembly 4's effect, need not extra power and supports, has broken away from the tradition and has passed through the mode that the couple is connected, and jaw assembly 3 passes through locking groove 5 locking retaining member 1, the unhook problem can not appear.

In some embodiments, as shown in fig. 1, the jaw assembly 3 comprises a plurality of jaws, and a reset assembly 4 is arranged between the jaws and the connecting seat 2; the first end part of the clamping jaw is rotationally connected with the connecting seat 2; the second end of each jaw is surrounded to form a locking groove 5.

In above-mentioned jaw assembly 3, each jack catch all can rotate for connecting seat 2, consequently, when retaining member 1 gets into locking groove 5 through importing and exporting, each jack catch all can rotate dodges for retaining member 1 gets into locking groove 5 smoothly.

Specifically, in order to make locking groove 5 play spacing effect to retaining member 1 constantly, a plurality of jack catchs are the form distribution of scattering around the axis of locking groove 5, and when retaining member 1 had the trend of breaking away from locking groove 5, retaining member 1 promoted the jack catch and rotated towards the direction of keeping away from locking groove 5 axis, and at this moment, the exit and entrance size of locking groove 5 reduced, caused the hindrance to retaining member 1 to restrict retaining member 1 in locking groove 5.

Jaw assembly 3 may include two, three, four, five, etc. jaws.

It should be noted that, the two first claws 31 and the two second claws 32 are arranged oppositely, and a certain gap may be formed between the two first claws 31 and the two second claws 32, so that when the locking member 1 enters the locking groove 5 through the first entrance/exit, the two first claws 31 do not touch the two second claws 32 after swinging. Certainly, there may be no gap between the two first claws 31 and the two second claws 32, and the two first claws 31 swing to push the two second claws 32 to rotate, so that when the locking member 1 smoothly enters the locking groove, the two first claws 31 and the two second claws 32 are reset at the same time.

In some embodiments, as shown in fig. 3, the second end of the jaw comprises a horizontal stop surface 33 and a vertical stop surface 34 connected to the horizontal stop surface 33; the horizontal limiting surface 33 is used for limiting the horizontal position of the locking member 1 so as to prevent the locking member 1 from being released from the locking groove 5 along the horizontal direction; the vertical stopper surface 34 protrudes outward toward the direction close to the axis of the locking groove 5 to define the vertical position of the locker 1, and to prevent the locker 1 from being removed from the locking groove 5 in the vertical direction.

The jaw structure can limit the freedom of the locking member 1 in three mutually orthogonal directions, and stably lock the locking member 1 in the locking groove 5.

As shown in fig. 3 and 4, the horizontal limiting surface 33 is an arc surface, so that the width of the entrance of the locking groove 5 is smaller than the maximum cross-sectional dimension of the locking groove 5.

Taking fig. 3 as an example to specifically describe, the horizontal limiting surfaces 33 on the first jaw 31 on the left side and the second jaw 32 on the left side are used to abut against one end of the locking member 1, the horizontal limiting surfaces 33 on the first jaw 31 on the right side and the second jaw 32 on the right side are used to abut against the other end of the locking member 1, so as to limit the displacement of the locking member 1 in the X-axis direction, meanwhile, since the horizontal limiting surfaces 33 are arc surfaces, the width of the inlet and outlet of the locking groove 5 is smaller than the maximum cross-sectional size of the locking groove 5, the horizontal limiting surfaces 33 on the four jaws jointly limit the displacement of the locking member 1 in the Y-axis direction, and the vertical limiting surfaces 34 on the four jaws jointly limit the displacement of the locking member 1.
