Why choose the upper suction lock structure for electric tailgate?

What is the quality of such a hot electric tailgate on the market? Needless to say, most of the electric tailgates currently on the market use the structure of the lower suction lock. Such products rely on the tension of the steel wire of the tooth box to pull the zipper installed at the lock position to realize the suction of the electric tailgate. , There may be no problem in a short time after installation. Once the time is long, due to the longer wire stress and the sway of the lock, the tail door may not be closed tightly, and the gap between the tail door and the body is uneven. It is inconsistent with the body surface difference, abnormal noises during driving, broken locks, etc. In serious cases, there will be a series of problems such as the electric tailgate cannot be opened in an emergency, which is serious irresponsibility for the owner. The following is a list of common problems of the electric tailgate with suction lock.

1. The gap between the left and right of the tailgate is inconsistent

2. The difference between the rear door and the body surface after installation is inconsistent

3. There is no pull-in action at the tailgate. This reason is due to the limited life of the zipper, which will increase the length of time and cause the tail door to not close tightly or simply not to close.

4. Abnormal sound of the tailgate during driving. Because the zipper lock has a chute to realize the pull-in since it has to slide, it must be impossible to clamp too tightly, and there must be a certain gap, otherwise, the pull-in cannot be carried out. The gap will cause the tailgate to sway left and right during the driving process, causing abnormal noise.

5. The movable cable breaks. Pulled by steel wire, the heavy tail door of SUV will inevitably be a huge test for the strength of the wire, especially at both ends (tooth box end and lock end), which is a high incidence area of ​​wire breakage. If it breaks, the tailgate cannot be closed, and the consequences are unimaginable.
