Fig. 2 is a schematic structural diagram of the locking device. As can be seen from fig. 2, the locking device 5 comprises: the locking mechanism comprises a shell 51, a guide hole 52, a locking bolt 53, a return spring 54, a cam 55 and a locking motor 56.
In this embodiment, for convenience of description, when the locking device 5 is in the locked state, one end of the latch 53 extending therefrom is referred to as a front end, and the other end thereof is referred to as a rear end, and a specific position to which the latch 53 extends at this time is referred to as a locked position.
As shown in fig. 2, the latch 53 penetrates the guide hole 52 and is slidably connected with the guide hole 52; the front end of the bolt 53 can enter and exit the guide hole 52 in an extensible way; the rear end of the latch tongue 53 contacts the outer edge of the cam 55; the return spring 54 is sleeved on the bolt 53 and positioned between the guide hole 52 and the cam 55; one end of a return spring 54 is connected with the shell 51, and the other end is connected with a bolt 53; the drive shaft of the lock motor 56 is connected to the axle of the cam 55.
In the implementation process, the bin door 2 is in an open state after the unloading is finished, the reset device 6 starts the reset action according to the instruction of the control device 7, and the execution part of the reset device 6 acts to enable the bin door 2 in the open state to be turned upwards and attached to the opening at the lower part of the vehicle body 1 to close the opening, so that the reset operation of the bin door 2 is finished.
After the bin gate 2 is reset, the bin gate 2 is closed and is in a fit state with the bottom opening of the vehicle body 1. At this time, the locking device 5 starts the locking operation according to the instruction of the control device 7.
The specific process is that the locking motor 56 is started by receiving a locking instruction of the control device 7, and drives the wheel shaft of the cam 55 connected with the locking motor to rotate, so that the cam 55 rotates along with the wheel shaft. In the rotation process of the cam 55, the shaft diameter of the contact part of the cam 55 and the rear end of the bolt 53 is gradually increased, the outer edge of the cam 55 generates thrust to the rear end of the bolt 53, the thrust overcomes the elastic force of a return spring 54 sleeved on the bolt 53, the bolt 53 extends forwards along the guide hole 52, the front end reaches the locking position, the door 2 is locked, and the joint state of the door and the opening at the lower part of the car body 1 is kept. The return spring 54 is now in a compressed state.

The specific process is that the locking motor 56 is started after receiving an unlocking instruction of the control device 7, the locking motor 56 drives the wheel shaft of the cam 55 to rotate, and then the cam 55 rotates along with the wheel shaft. In the rotation process of the cam 55, the shaft diameter of the contact portion between the cam 55 and the rear end of the latch 53 is gradually reduced, and the thrust of the outer edge of the cam 55 to the rear end of the latch 53 disappears. At this time, the latch 53 moves in the direction of the cam 55 along the guide hole 52 by the elastic force of the return spring 54 in the compressed state. When the front end of the latch tongue 53 leaves the locking position, the unlocking action of the bin door 2 is completed.
