Abstract

The invention discloses a car key battery assembly, which includes a battery fixing case. The car key battery structure also includes a metal shrapnel and a battery. The metal shrapnel includes a positive electrode piece and a negative electrode piece. The battery fixing case includes a bottom plate and a The arc-shaped side wall, the two ends of the upper edge of the arc-shaped side wall are connected by a limit arm, the bottom plate, the arc-shaped side wall, and the limit arm form a battery slot structure for the battery to be placed in, and the upper surface of the bottom plate is provided with a depression The concave surface is provided with a limit bump, and the negative electrode is provided with a limit slot that is sleeved on the limit bump. One end of the negative electrode is the battery clamping end, and the other end of the negative electrode has an insert piece. Slots are provided on the curved side walls. By adopting the above structure, the present invention has the following advantages: good elasticity, high conductivity, long life, elimination of oxidation at the contact point between the shrapnel and the battery, and simple assembly.

Description

technical field [0001] The invention relates to the technical field of car keys, in particular to a car key battery assembly. Background technique [0002] As the remote control key is widely used in automobiles, the functions and shapes of the remote control key are more and more, and the pursuit is getting higher and higher. From a structural point of view, the shapes of keys with different shapes also put more requirements on the structural design of the remote control key. For the remote control key, the shrapnel function is the most direct and basic requirement. Therefore, in this case, a battery sheet with simple structure, simple process and strong versatility is designed. The metal shrapnel needs to be economical, reliable in structure, small in space, and no cost increase to solve the problem of short service life for most products on the market. , in order to better adapt to the changing shape of the remote control key. At present, the usual car keys have more o...
