Battery mounting structure of automobile key

Technical Field

The utility model belongs to the technical field of the automobile body, concretely relates to battery mounting structure of car key.

Background

For a device using the button cell, the mounting stability of the button cell is poor due to the special structure of the button cell.

For a device which is not very mobile, such as a weight scale, the deficiency does not have great influence on the use, but for a device which is carried around, such as a car remote control key, the deficiency can seriously affect the use experience. In order to overcome the defects, the common solution idea is to preferentially improve the installation stability and ensure the working stability. But often causes the defects that the product parts are difficult to disassemble and are easy to loosen and fall off after being disassembled.

For example, in our national patent application (publication number: CN 104466056B; published as 2017.02.22), a key battery assembly for a vehicle is disclosed, in which a button battery is inserted into a battery tank through a side surface and fixed between a bottom plate, an arc-shaped side wall and a limit arm, and the button battery is fixed on a PCBA plate in a side-in type manner. According to the method for fixing the button battery, after the automobile remote control key is installed, the battery to be replaced can be taken out only by arranging the large opening and closing cover, the sealing area of the opening and closing cover is large, and the inclined plane on the opening and closing cover cannot pass the waterproof verification of the washing machine after the opening and closing cover is closed.

For example, a button cell positive spring plate and a button cell mounting structure for a remote control key are disclosed in the national patent application document (publication number: CN 208240753U; published as 2018.12.14). although the button cell mounting structure has an upward opening, the size of the opening of an opening and closing cover can be reduced, the button cell cannot be effectively fixed on a battery panel by the positive spring plate, and the button cell needs to be fixed on the battery panel by a shell matching with a fixing frame and a compression ring so as to be communicated with a circuit of the remote control key.
