Since the lock catch 320 is disposed on the tarpaulin cover 200 and the lock catch 310 is disposed on the vehicle cabin 100, the first unlocking position and the first locking position can be switched by the cooperation or separation between the lock catch 320 and the lock catch 310, and the connection or separation between the tarpaulin cover 200 and the vehicle cabin 100 can be realized. In addition, when the locking head 410 is engaged with the locking hook 420, the latch 310 can be clamped between the vehicle compartment 100 and the locking head 410, thereby locking the first locking position and achieving locking of the first locking member 300 by the second locking member 400.

Fig. 3 is a schematic structural view of a latch according to an embodiment of the present utility model.

Further, referring to fig. 3, the latch 310 includes a fixing sleeve 311, a lock shaft 312 engaged with the fixing sleeve 311, and a limiting portion 313 disposed at a top end of the lock shaft 312, and the latch 320 is provided with a lock hole (not shown) and a notch (not shown) communicating with the lock hole.

Under the action of external force, the lock shaft 312 moves along the axial direction of the fixed sleeve 311, and the lock shaft 312 enters the lock hole through the notch, and the limiting part 313 is abutted against the lock catch 320, so as to limit the transverse displacement and the vertical displacement between the tarpaulin cover 200 and the carriage 100.

However, in order to secure the locking effect of the second locking member 400 on the first locking member 300, a gap may be provided between the locking head 410 and the vehicle compartment 100, i.e., in the second locking position, the locking head 410 is not allowed to directly contact the vehicle compartment 100, but a gap for accommodating the stopper 314 is formed.

It should be noted that, although the stop portion 314 and the limit portion 313 are disposed at two ends of the lock shaft 312, the two exert main locking effects in the first locking member 300 and the second locking member 400, respectively. However, in order to achieve the interlocking locking between the first locking member 300 and the second locking member 400, the stop portion 314 and the limiting portion 313 should be oriented identically, that is, both can rotate synchronously with the rotation of the lock shaft 312.

Preferably, the stop 314 may be a baffle, and the width of the baffle is greater than the distance between the locking head 410 and the lower edge of the cross member of the car 100. In addition to being able to cooperate with locking head 410 in the second locking position, stop 314 may also be used as an operating element for a user to rotate latch 310, i.e., the user may operate latch 310 to rotate by holding stop 314.

In some embodiments, the locking device may be multiple, and the multiple locking devices are evenly distributed along the circumference of the cabin 100. The arrangement of a plurality of locking devices can further improve the connection stability between the tarpaulin cover 200 and the carriage 100.

In addition, the embodiment of the utility model also provides an automatic tarpaulin system which comprises the locking device. The automatic tarpaulin system is provided with the locking device, and the safety and reliability of the automatic tarpaulin system are improved by exerting the locking effect of the locking device.
