Description

Power Battery

This creation is about a power battery, which refers to a power battery that has waterproof and dustproof effects.

Electric motor vehicles are a kind of means of low air pollution and low noise. In recent years, governments of various countries have vigorously promoted green energy and environmental protection, which has made the development of electric motor vehicles pay attention to them. Many electric motor vehicles have also been introduced.

Generally, the power source of the electric motor vehicle is electric power. Therefore, it is necessary to install a battery in the electric motor vehicle, and drive the motor through the electric power of the battery to achieve the purpose of riding.

The battery of the early electric motor vehicle is not removable. Therefore, when the battery has no power, the battery needs to be charged through the household power supply. This charging method needs to overcome the distance between the electric motor vehicle and the power supply, which causes inconvenience in charging, especially In densely populated residential areas, electric vehicles are inevitably parked in community parking lots, and electric vehicles cannot be moved to their homes for charging. Therefore, there is no way to effectively increase the penetration rate of electric motor vehicles.

In order to solve the above problems, there is a manufacturer to introduce a motor vehicle with a replaceable battery. When the battery is dead, the user can continue to ride the electric motor by replacing the battery. This method is fast and efficient. Accepted by consumers.

However, because the locomotive will be exposed to the sun and rain when riding outdoors, when the temperature is low or temperature When the temperature is high, the battery is easily affected by the heat expansion and contraction, so the sealing performance of the battery is directly affected. When the battery sealing property is lost, the battery loses the waterproof property, especially when the battery is replaced. It is more likely to cause water seepage and, in the end, damage the battery.

It can be seen that there are still many shortcomings in the above-mentioned conventional batteries, which is not a good designer, and needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional batteries, the creators of this case have improved and innovated, and after years of painstaking research, they finally succeeded in research and development of this power battery.

The power battery used in the electric motor car needs to be plugged and replaced when the power battery has no electric energy. Therefore, the power battery needs to have a certain degree of waterproof function to prolong the service life of the power battery.

In order to make the power battery waterproof, the conventional power battery will use the adhesive to bond the cover body and the body. This way, the power battery can be waterproof, but when the battery core is heated and contracted due to the external environment, it is adhered. The glue cannot effectively fix the cover body and the body tightly, so the waterproof function of the power battery is lost, and the user may be in danger of using it under long-term use.

The purpose of this creation is a power battery with waterproof and dustproof effects.

The power battery of the present invention comprises: a body having an accommodating space formed therein, wherein the inner edges of the two ends of the accommodating space are respectively formed with a pair of connecting slots, and the accommodating space houses a battery core; The system is extended with a cover protrusion, and the top cover protrusion is recessed a bottom cover is disposed in the mating groove of the main body through the top cover convex portion, so that the top cover is connected to the top end of the main body; a bottom cover is extended with a bottom cover convex portion, and the bottom cover a recess is formed in the convex portion, and the bottom cover is inserted into the mating groove of the body through the bottom cover convex portion, so that the bottom cover is connected to the bottom end of the body; and the bottom cover is provided An electrical connector that can be connected in a directional manner; a gasket is respectively disposed in the recess of the top cover and the bottom cover, and an outer edge of the gasket extends outwardly to protrude with a tight portion to make the gasket pass through The portion is in close fitting with the inner side wall of the mating groove of the body.

The power battery disclosed in the present invention, wherein the battery core is a lithium battery.

In the power battery disclosed in the present invention, the outer diameter of the top cover protrusion is smaller than the top cover.
