Problems solved by technology

[0002] As lithium batteries are more and more widely used in people's daily life, the waterproof problem of lithium batteries has become a new topic and direction of people's research. The current single lithium battery adopts conventional packaging technology, and there is a gap between the battery and the terminal equipment. It is the use of clearance fit, which cannot meet the waterproof requirements at all;
[0003] The existing lithium battery waterproof method has certain disadvantages in use, (1), in order to realize the waterproof between the battery and the terminal equipment, the existing common practice is to set a waterproof sealing ring on the battery, which is connected to the battery. The tightness of the fit cannot be guaranteed, and there is a risk of water ingress. At the same time, the connection between the metal contact piece on the battery and the battery plastic case also adopts a gap fit, which can easily cause water to enter the battery and cause damage to the battery; (2), The existing waterproof treatment of lithium batteries is to protect the lithium batteries before they encounter water. When these water discharge treatments are damaged or have problems, they cannot be repaired in time. Management and protection, so that the waterproof problems that have already occurred cannot be discovered in time, making these problems continue to deteriorate, and eventually lead to damage to the lithium battery, and can only be repaired after damage, resulting in certain losses. For this reason, we propose a A lithium battery waterproof method

Abstract

The invention discloses a lithium battery waterproof method, comprising the following steps: making a sponge case: measuring the size of the lithium battery, and making the sponge case according to the size; making the waterproof case: using an injection molding machine to inject molding into the injection mold; waterproof installation: sequentially The sponge shell, buzzer, auxiliary lithium battery, and waterproof shell are installed on the surface of the lithium battery; sealing treatment: insert the copper column into the outlet. The lithium battery waterproof method described in the present invention, firstly, can better waterproof the lithium battery, improve the waterproof ability of the lithium battery, and at the same time better protect the internal lithium battery from damage, and improve the installability of the lithium battery when in use , secondly, when the waterproof shell is damaged or water enters, the sponge shell absorbs the water, and the buzzer and the auxiliary lithium battery are energized through the water-containing sponge, so that the auxiliary lithium battery energizes the buzzer, sends out an alarm, and Timely reminders bring better prospects for use.
