Abstract

The invention provides a falling-prevention battery. The falling-prevention battery comprises a battery cell, a lower shell, an upper shell and a support, wherein the upper shell is covered with the lower shell, the support is used for fixing the battery cell, the support is arranged in the lower shell, a first clamping boss is arranged on the support, the protruding height of the first clamping boss is gradually reduced from top to bottom, a second clamping boss is arranged on the lower shell, the protruding height of the second clamping boss is gradually increased from top to bottom, and anupper end surface of the first clamping boss is attached onto a lower end surface of the second clamping boss so that the support is clamped with the lower shell. The falling-prevention battery provided by the invention is simple in structure and is convenient to assemble, the battery cell can be directly pressed into the lower shell, the assembly time is saved, the battery production efficiency is improved, and the situation that the battery cell collides with the shell to cause damage to the battery cell and crack to a covering position of the upper shell and the lower shell during falling of the battery also can be prevented.

Description

Technical field [0001] The present invention belongs to the field of battery technology, and more specifically, relates to an anti-drop battery. Background technique [0002] Lithium-ion battery is a secondary battery (ie rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes. It has the advantages of high working voltage, high energy density, long cycle life, low self-discharge, and high environmental protection. , Widely used in mobile phones, notebook computers, micro cameras, aerospace and other industries. [0003] Lithium-ion batteries are easy to fall on the concrete floor due to negligence during use. Many lithium-ion batteries are designed with a screw-fixed technical solution, and the internal battery cell is fixed to the shell by screws to meet the drop test. It is required to avoid damage to the lithium-ion battery when it is dropped. However, for the convenience of application, the volume of lithium-ion b...
