Detailed Description
In the embodiment, as shown in fig. 1 to 5, an automobile key button assembly structure includes a housing 1 and a button 2 mounted on the housing 1, where the button 2 can be pressed in 4 directions, and 4 pressing bosses 203 are respectively arranged on four directions of the back of the button 2 to cooperate with a circuit board in a key to realize circuit conduction.
Because the button is small in size, for convenient processing, the shell 1 is provided with a sinking platform 101 matched with the button 2, and the button 2 is arranged in the sinking platform 101. A support 3 which is formed with the shell 1 through secondary injection molding is arranged in the sinking platform 101, the support 3 is in a cross structure and can be stretched and deformed, a closed shifting block placing cavity 301 is arranged in the middle of the support 3, a shifting block 4 is arranged in the shifting block placing cavity 301, a rotating pin 302 is further arranged on the support 3, and a rotating pin mounting hole 401 matched with the rotating pin 302 is formed in the shifting block 4; the shifting block 4 is further provided with a shifting block rotating pin 402, the shifting block rotating pin 402 and the rotating pin mounting hole 401 are arranged at 90 degrees, and the button 2 is provided with a shifting block rotating pin mounting hole 201 matched with the shifting block rotating pin 402. In order to facilitate the installation of the shifting block rotating pin 402, two cantilevers 202 are arranged on the button 2, the cantilevers 202 can be deformed under stress in a matching mode, and the shifting block rotating pin installation hole 201 is formed in the cantilevers 202.
