Abstract

The invention relates to a key structure which is used on a vehicle-mounted sound. The key comprises a key cap and a wall, wherein a U-shaped button position and a locating column for being clamped and connected with the key wall are arranged below the key cap, the wall is of a hollow structure, the side wall at the button position of the key cap corresponding to the wall is provided with a groove which is the same as the protruding button position in shape and size, a side wall at the locating column corresponding to the wall is provided with a concave hole; and a locating wall is also arranged corresponding to the peripheral shape of the wall below the key cap. Compared with the prior art, by using the key structure provided by the invention, the key cap and the wall at the lower end can be respectively molded and then assembled for use, the mould structure used for the molding is relatively simple, the injection and assembling time of the key is short, more complex devices such as a double-colored injection machine, a ultrasonic welding device and the like cannot are not required to be used; compared with the existing double-colored key and the key molded by ultrasonic welding, the cost of the key provided by the invention is lower and the quality is easier to control.

Description

technical field

[0001] The invention relates to a button structure, in particular to a button used in a car audio system. Background technique

[0002] On car audio, the use of buttons is very common, and the shapes of buttons are also colorful and have various structures. In addition to realizing its due function, the key also requires the characters to be transparent and even, and there should be no light leakage around the key. At present, there are three main technical solutions to achieve the above requirements: (1) Integrated button, the whole button is formed of one material, and oil is sprayed around the button to avoid light leakage. This method is only suitable for buttons with a relatively simple structure and low requirements on light leakage. It is difficult to spray oil on buttons with complex structures, which cannot completely solve the problem of light leakage. (2) Two-color injection molding button, that is, a two-shot molding machine is used to use two ...
