The locking lever 8244 is locked to the universal wheels 820 relatively fixed in such a manner that the operation member 8248 is inserted into the locking hole 8241, thereby locking each universal wheel 820 in the direction, and the elastic member 8246 is compressed to generate elastic force. Meanwhile, the operating member 8248 may be operated to unlock the locking lever 8244, and the locking lever 8244 may be separated from the locking hole 8241 and the universal wheel 820 under the elastic force, thereby allowing the universal wheel 820 to resume 360 degrees of rotation.

Referring to fig. 10 and 11, the armrest 3 includes two handles 31 symmetrically disposed. Handles 31 are secured to left side 26 and right side 28, respectively. And the two handles 31 extend in directions away from the hopper 4, respectively. Each handle 31 comprises a fixed section 311 and an expansion section 313 extending outwards from the fixed section 311 in a direction away from the hopper 4, wherein one end of the expansion section 313 away from the fixed section 311 extends in a direction away from the hopper 4 to form a main handle 310. The main handle 310 is provided with a grip portion 3101.

Referring to fig. 23 in combination, an automatic skip car according to a second embodiment is provided. The automatic skip bucket type small-sized carrier provided by the third embodiment is different from the automatic skip bucket type small-sized carrier provided by the first embodiment in that: each handle 31 is provided with a main handle 310 and auxiliary bars 312 extending in parallel from the outside of the main handle 310. The primary handle 310 is simultaneously bent outwardly to extend the secondary rod 312. The auxiliary lever 312 is provided in parallel with the main handle 310. The auxiliary lever 312 is thinner than the main handle 310. The auxiliary rod 312 is used for preventing the hands of the user from being scraped and bumped by other objects when the automatic skip type small-sized carrier in a small space turns, and plays a role in protection.

Referring to fig. 20-21 in combination, either one of the handles 31 is a safety hand brake 315 for braking the automated skip car 1000. The other is provided with a throttle control assembly 317 for controlling the moving speed of the automatic skip car. In the present embodiment, a safety hand brake 315 is provided on the handle 31 provided on the left side 26, and a throttle control assembly 317 is provided on the handle 31 provided on the right side 26.

The safety manual brake 315 includes a trigger portion 3150 fixed to the main handle 310 and a pressing piece 3152 rotatably coupled to the trigger portion 3150. The triggering part 3150 is electrically connected with the electromagnetic brake 816 through a cable, and is used for triggering the electromagnetic brake to work or stop working. The electromagnetic brake 816 is further electrically connected to the trigger brake assembly 814, and is configured to trigger the brake assembly 814 to brake the automatic skip bucket mini-truck 1000. The trigger portion 3150 is sleeved on the main handle 310 and is disposed adjacent to the holding portion 3101, and the trigger portion 3150 is provided with a trigger switch (not shown). The pressing piece 3152 is located above the holding portion 3101 and partially opposite to the holding portion 3101, and a certain gap exists between the pressing piece 3152 and the holding portion 310. Two pivoting structures (not shown) are symmetrically disposed on one side of the trigger portion 3150 near the end of the handle 31. The side of the tab 3152 remote from the end of the handle 31 is provided with two fittings (not shown). The assembly members are spaced apart and pivotally connected to the two pivot structures, respectively, such that the compression member 3152 is rotatably coupled to the trigger portion 3150. Each pivot structure comprises a pair of mounting blocks which are oppositely arranged, and each assembly part is arranged between the two mounting blocks through a rotating shaft.

When the pressing piece 3152 is gripped together with the gripping portion 3101 and approaches the gripping portion 3101, the pressing piece 3152 triggers the trigger switch to be closed, so as to generate a control signal to control the electromagnetic brake 816 to operate, so that the brake assembly 814 cannot act on the wheel assembly 8 and the automatic skip type small-sized carrier 1000 can travel. When the presser 3152 is released and separated from the grip portion 3101, the trigger switch is turned on, and the electromagnetic brake 816 is not controlled to operate, so that the brake assembly 814 acts on the wheel assembly 8, and the automated guided vehicle 1000 cannot continue to travel. More specifically, the safety manual brake 315 is electrically connected to the electromagnetic brake 816, and when the safety manual brake 315 is held, the electromagnetic brake 816 is energized, so that the electromagnetic brake 816 releases the brake assembly 814, and the vehicle can travel. The braking mode of the safety hand brake 315 and the electromagnetic brake 816 can enable the vehicle to brake rapidly in emergency, the brake state is achieved by releasing the handle, and the electric small-sized carrier is effectively prevented from sliding when the electric small-sized carrier is parked.

Because the safety hand brake 315 is arranged on the handle 31 of the operating device, the vehicle can be controlled to walk or brake by holding or loosening the safety hand brake 315, that is, the small-sized carrier can be braked by loosening the safety hand brake 315, and the vehicle can travel only by holding the safety hand brake 315, so that the vehicle is safer and more reliable.

Referring to fig. 22 in combination, an automated skip car according to a second embodiment is illustrated. The second embodiment differs from the first embodiment in that the second embodiment is provided with a cross bar 48 on the side of the hopper close to the console 2.
