Embodiment Construction

[0021] Such as Figure 1 to Figure 7 A car key battery assembly is shown, which includes a battery fixing case. The car key battery structure also includes a metal shrapnel and a battery 2. The metal shrapnel includes a positive electrode piece 3 and a negative electrode piece 4. The battery fixing case includes a bottom plate 1 and a battery along the bottom plate 1. The arc-shaped side wall 5 arranged on the edge, the two ends of the upper edge of the arc-shaped side wall 5 are connected by the limit arm 6, and the bottom plate 1, the arc-shaped side wall 5, and the limit arm 6 form a battery for the battery 2 to put in. Slot structure, the upper end surface of the base plate 1 is provided with a concave surface, the concave surface is provided with a limit bump 7, the negative plate 4 is provided with a limit slot 10 sleeved on the limit bump 7, and the limit bump 7 Snap into the limiting slot 10 to form a buckle structure. One end of the negative electrode sheet 4 is the ...

Abstract

The invention discloses a car key battery assembly which comprises a battery fixing housing, wherein the car key battery structure further comprises a metal leaf spring and a battery; the metal leaf spring comprises a positive electrode plate and a negative electrode plate; the battery fixing housing comprises a bottom plate, wherein an arc-shaped side wall is arranged along the edge of the bottom plate, the two ends of an upper end edge of the arc-shaped side wall are connected through a limiting arm; the bottom plate, the arc-shaped side wall and the limiting arm form a battery insertion slot structure for placing a battery; a sunken surface is further arranged on the upper end surface of the bottom plate; a limiting lug is arranged on the sunken surface; a limiting slot hole sleeved on the limiting lug is arranged on the negative electrode plate; one end of the negative electrode plate is a battery clamping end, the other end of the negative electrode plate is extended with an insertion sheet; and an insertion slot is formed in the arc-shaped side wall. By adopting the structure, the car key battery assembly has the advantages of good elasticity, high conductive performance, a long service life, capacity of relieving the oxidization of a contact point of the spring leaf and the battery, and simple assembling.

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 key shapes with different shapes also put forward more requirements for 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 does not increase cost to solve the problem of short service life of most products on the market. , in order to better adapt to the requirements of the changeable shape of the remote control key. At presen...
