[0002] With the development of modern automobile technology, the requirements for automobile intelligence, safety and humanization are becoming higher and higher.

[0003] The anti-pinch function of the car tailgate is an important part of the humanization of the car. Its main function is to identify and send a signal when the car tailgate is clamped by an obstacle during the closing process of the car tailgate, so that the car tailgate stops or returns, which can prevent the car tailgate motor from burning out and people from being injured.

[0004] There are basically two ways to install the anti-pinch strip on the tailgate of an automobile in the prior art.

[0005] The first method is to connect the anti-pinch strip by bonding and clamping. The process generally includes cleaning, primer coating and gluing. After bonding, the two ends of the anti-pinch strip are clamped on the tailgate of the car. The disadvantage is that the process is complicated and the cost is high.

[0006] The second method is to install the anti-pinch strip on the bracket by gluing, and the bracket is then connected to the tailgate by bolts. This method requires an additional bracket, which increases the cost and reduces the appearance. Utility Model Content
