Embodiment

[0020] Example: such as Figure 1-3 As shown, a lithium battery anti-drop device of the present invention includes a lithium battery body 1 and an outer box 2, which is convenient for filling a vibration-damping rubber 3 between the outer box 2 and the battery body 1, and when the lithium battery falls, it can pass The damping spring 3 plays the role of damping; the lithium battery body 1 is fixed inside the outer box body 2, and the space between the outer box body 2 and the lithium battery body 1 is filled with a vibration-damping rubber 3, and there are several vibration-damping rubbers 3 inside. The tank body is convenient for when the lithium battery is not dropped, the shock absorber 4 and the buffer member 5 are fixed in the tank body, and when the lithium battery is dropped, the shock absorber 4 and the buffer member 5 pop up, which can play a role in cushioning and reducing The effect of vibration; and the tank is provided with several damping parts 4 and buffer parts...

Abstract

The invention discloses a lithium battery drop resistance device. An acceleration sensor is arranged between an outer tank body and a lithium battery body, the acceleration of a moving lithium battery can be detected through the acceleration sensor, and thus whether the lithium battery is dropped off or not can be judged; furthermore a plurality of damping parts and buffer parts are arranged between the lithium battery and the outer tank body, and furthermore a control chip is configured, so that all electromagnetic valves are controlled to be opened by the control chip when the acceleration sensor detects that the lithium battery is dropped off, a compressed spring is popped out, honeycomb rubber is also popped out, then the lithium battery can be fixed among all pieces of honeycomb rubber and is prevented from being directly dropped onto the ground, and a damping function is achieved; and meanwhile, after the electromagnetic valve of a compressed air cylinder is opened, compressed air is fed into an airbag, the airbag is popped out, after the airbag is inflated, a buffer function is achieved, and thus the lithium battery can be further prevented from being damaged.

Description

technical field [0001] The invention relates to an anti-drop device, in particular to an anti-drop device for a lithium battery. Background technique [0002] Lithium batteries refer to batteries containing lithium (including metal lithium, lithium alloys, lithium ions, and lithium polymers) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. [0003] With the development of science and technology, more and more technology products need to use lithium batteries, therefore, the demand for lithium batteries in the market is also increasing. When the lithium battery is in use, it is the main power supply component. Therefore, if the lithium battery is damaged or malfunctions, the entire product will be unusable. At present, technology products on the market tend to be small and compact. However, as the size of prod...
