Embodiment Construction
[0019] Examples such as Figures 1 to 5 As shown, a car key button assembly structure includes a casing 1 and a button 2 installed on the casing 1. The button 2 can be pressed in 4 directions, and four pressing protrusions are respectively arranged on the back of the button 2 in four directions. The platform 203 cooperates with the circuit board in the key to realize the conduction of the circuit.
[0020] Due to the small volume of the button, for the convenience of processing, the shell 1 is provided with a sunken platform 101 suitable for the button 2, and the button 2 is placed in the sunken platform 101. A bracket 3 that is injection-molded together with the casing 1 is provided inside the sinking platform 101. The bracket 3 has a cross-shaped structure and can be stretched and deformed. A closed cavity 301 for placing a block is arranged in the middle of the bracket 3. A shifting block 4 is arranged in the shifting block placement chamber 301, and a rotating pin 302 is ...

The invention discloses an automobile key button assembly structure and a preparation method thereof. The automobile key button assembly structure comprises a shell and a button installed on the shell. The shell is provided with a sinking table matched with the button, and the button is arranged in the sinking table; a bracket which is formed together with the shell through secondary injection molding is arranged in the sinking table; the support is of a cross-shaped structure and can be stretched and deformed; a sealed shifting block containing cavity is formed in the middle of the support, ashifting block is arranged in the shifting block containing cavity, a rotating pin is further arranged on the support, and a rotating pin installation hole matched with the rotating pin is formed inthe shifting block. The shifting block is further provided with a shifting block rotating pin, the included angle between the shifting block rotating pin and the rotating pin installation hole is 90 degrees, and the button is provided with a shifting block rotating pin installation hole matched with the shifting block rotating pin. The assembly structure is simple in structure, convenient to install, high in assembly efficiency, good in structural strength and capable of being widely applied to the field of automobile keys.
Description
technical field [0001] The invention relates to the field of automobile smart keys, in particular to an automobile key button assembly structure and a preparation method thereof. Background technique [0002] Usually, the button structure of the car key is relatively simple, and the button and the housing are connected by a snap-fit structure, and the buttons are all independent entities. Due to the small size of the button, the parts to be assembled are relatively small. Therefore, generally, a two-way pressing structure is used for assembly. With the continuous change of design, some button structures that can be pressed in four directions have appeared, but most of these structural parts are relatively complicated, which greatly increases the manufacturing cost and processing difficulty of the parts. Therefore, it is necessary to develop a four-way push button with easy assembly and simple structure to meet the ever-changing market requirements. Contents of the inven...
