Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a projection kick module bracket installation structure. Background Art
[0002] As the electric tailgate system develops towards intelligence, convenience and contactlessness, the kick module is an important module for contactless opening of the electric tailgate. In order to improve the recognition rate and visibility of the kick module, more and more manufacturers have adopted projection foot modules instead of capacitive foot modules. The projection foot module is mainly composed of a projection optical machine and a TOF time-of-flight sensor. Compared with the capacitive foot module, the projection foot module has more functions, a high motion recognition rate, and a stronger demand for information interaction. Figure 1 The existing projection footrest module mounting bracket shown is connected to the rear bumper by bolts. Due to the machining and assembly clearance tolerance of the parts, the mounting bracket is prone to collide with the rear bumper during vehicle driving, especially when passing through an unstable road section, causing abnormal noise, which affects driving comfort. Therefore, a new projection kick module bracket mounting structure needs to be invented. Utility Model Content
