Automobile combined key

Abstract

The invention relates to the technical field of automobiles, in particular to an automobile combined key. The keyboard comprises a character plate (1), keys (2), a sliding block (3), a shading plate (4), ejector pin (5) mechanisms, a lamp panel (8) and a rack part (9), wherein the keys (2) are connected to the sliding block (3) to form a key (2) combination, and the character plate (1), the shading plate (4) and the rack part (9) are fixed and form a sliding cavity; the ejector pin (5) mechanisms are arranged at two sides of the shading plate (4); inclined arc faces (10) allowing the ejector pin (5) mechanisms to abut against are arranged on the two sides of the sliding block (3), the lamp panel (8) is arranged on the rack part (9) and provided with a signal transmission switch (12), and atriggering part (11) used for triggering the signal transmission switch (12) is arranged on the lower portion of the sliding block (3). The automobile combined key can meet various force displacementcurve requirements, and is low in poor contact risk and good in durability.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile combination key. Background technique [0002] With the rapid development of my country's economy, various types of cars can be seen everywhere in various cities. With more and more vehicles, people's demand for various types of driving is also increasing. Among them, the gear operation parts are the most obvious changes in recent years. Now on the market, in addition to the traditional gear operation method, there are also push-button electronic shifters. [0003] The button-type electronic shifter in the prior art mainly uses silicone buttons. The working principle of the silicone buttons is: when the silicone button contacts move down to the maximum stroke position, they contact the corresponding contacts on the circuit board, thereby connecting the circuit board. The upper loop transmits signals and lights up characters, that is, the silicone key is mainly...

[0003] The button-type electronic shifter in the prior art mainly uses silicone buttons. The working principle of the silicone buttons is: when the silicone button contacts move down to the maximum stroke position, they contact the corresponding contacts on the circuit board, thereby connecting the circuit board. The upper loop transmits signals and lights up characters, that is, the silicone key is mainly deformed through the silicone skirt, thereby providing key force and return force, but since the force-displacement curve of the silicone key is determined by the structure of the silicone skirt, it can only meet a certain requirement. The force-displacement curve requirements of different shapes, and because the silicone keypad transmits signals in the form of contact contact, there is a high risk of poor contact (such as when foreign objects such as dust are involved), and its durability is also poor
