Button mechanism of car air conditioner controller

Abstract

The present invention discloses a car air conditioner controller key mechanism which comprises a shell, a key body, a key switch and a circuit board. A clamping hook mechanism extends into a shell inner wall lower part trench from the periphery of the outer wall lower part of the key body, and a shell inner wall is provided with a limit mechanism which limits the key body from moving out of the shell. According to the car air conditioner controller key mechanism, by employing the above structure, the car air conditioner controller key mechanism has the advantages that the lower size of the key body is large, the upper size of the key body is small, the key body can only be installed from the back side of the shell, and the key body can not go through a shell key hole in the whole from the back side. The movement stroke of the key body is controlled through the clamping hook on the key body, and the key body and shell movement direction gap is strictly controlled. The normal operation of the key can be ensured according to the gap, only the clamping hook of the key body can be in contact with the shell, and a noise is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to a button mechanism of an automobile air conditioner controller. Background technique [0002] The general structure of the existing automotive air-conditioning controller key mechanism is: the key body is installed on the housing from the front, and the movement stroke of the key is limited by several cantilever hooks. The disadvantages of this button mechanism are: 1. The noise is large when pressing the button, which affects the comfort of the driver; 2. In order to reduce the noise when the button is operated, the wall thickness of the hook will be thinner, and the clamping force of the hook on the housing will be lower. Weaker, so that when the front of the controller suffers a large impact, the hook will slip off and cause the button body to fall off from the casing and fly out. Contents of the invention [0003] The technical problem to be solved by t...
