A driving member 3 is slidably arranged in the support frame 1 in the front-to-back direction, and a spring is arranged between the rear end of the driving member 3 and the support frame 1. A lock tongue 4 is arranged in the support frame 1. A first connecting column 5 and a second connecting column 6 are respectively connected to the lock tongue 4 from the back to the front, and both ends of the first connecting column 5 are rotatably arranged on the support frame 1 to realize the rotation of the lock tongue 4, and the second connecting column 6 is slidably arranged on the support frame 1 to realize the sliding and unlocking functions. A sliding groove 34 is provided at the lower end of the driving member 3, and the sliding groove 34 is arranged to be inclined upward from the back to the front, and the second connecting column 6 is penetrated into the sliding groove 34.

[0024] like Figure 6 As shown, the working principle of the utility model is: when the soft top of the car is opened or closed, the soft top will move along the roof guide rail, and the guide rod on the soft top will move. When the guide rod and the inclined surface of the lock tongue 4 are in contact, the lock tongue 4 will be pushed up. When the guide rod is in place, the lock tongue 4 will fall under the action of the driving member 3 and the spring to achieve the locking function; when unlocking, it is only necessary to push the driving member 3, and the driving member 3 will drive the lock tongue to move upward through the second connecting column 6 to achieve the unlocking function.

[0025] The utility model realizes self-locking by cooperating with the lock tongue through the movement of the guide rod, and then drives the second connecting column to move through the movement of the driving member, and then drives the lock tongue to rotate along the first connecting column to realize unlocking. The whole device does not involve a connecting rod mechanism, and the structure is lighter than the connecting rod, the structure is simple, the volume is small, and the cost is low.
