Tire pressure detector

A tire pressure detector comprises a battery and a circuit board which are arranged between a shell and a cover body, and the battery is electrically connected with the circuit board. Wherein the shell is provided with a peripheral wall and an inner wall, the peripheral wall is connected with the cover body through the upper edge of the peripheral wall, the inner wall is provided with an inner connecting face and an outer peripheral face, the battery is placed on the inner side of the inner wall and partially makes contact with the inner connecting face, and a gap is reserved between the outerperipheral face of the inner wall and the peripheral wall. When the battery is placed on the inner side of the inner wall of the shell and the inner wall deforms towards the peripheral wall due to external force, the gap can prevent the peripheral wall from deforming due to external force linkage. 一种胎压侦测器，包括在一壳体与一盖体之间放置一电池与一电路板，所述电池与所述电路板电性连接。其中壳体具有一周壁以及一内墙，所述周壁以所述周壁的上缘与所述盖体连接，所述内墙具有一内接面与一外周面，其中所述电池放置于所述内墙内侧且部分与所述内接面接触，所
