Detailed Description

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiment(s) may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

Referring to fig. 1 to 3, a proximity switch and limit block mounting bracket assembly of a passenger car rear viewing door comprises a base 1 welded on a rear surrounding framework viewing door upright, a limit block bracket 2 screwed on the base 1 through two groups of bolts, a proximity switch bracket 3 screwed on the limit block bracket 2, and a limit block 4 mounted on the limit block bracket 2.

Referring to fig. 3 and 7, the base 1 is a hollow rectangular tube, and the base 1 is provided with a limiting block bracket mounting hole 11, so that the mounting and adjustment are more convenient due to the hollow structure.
