TECHNICAL FIELD

[0001] The application relates to the technical field of battery components, in particular to a new energy automobile battery shell. BACKGROUND

[0002] The driving motor system of a new energy automobile is one of the three core systems of a vehicle and is the main driving source of the vehicle, and the characteristics of the driving motor system directly determine the power performance, economic performance and user driving experience of the vehicle. The commonly used driving motors of new energy automobiles, in particular pure electric vehicles, include four types of DC motors, asynchronous motors, permanent magnet synchronous motors and switched reluctance motors. These motors have different characteristics. For example, the permanent magnet synchronous motor is widely used in new energy automobiles due to its high efficiency, high density, light weight and energy recovery function.

[0003] In the related art, the new energy automobile battery shell is an important component for protecting the safety of the battery, and the selection and design of the material of the new energy automobile battery shell have a direct impact on the performance of the electric vehicle. However, the current battery shell has poor moisture-proof capability and is difficult to effectively isolate the intrusion of moisture and humidity, which easily causes damage to the internal battery, and therefore needs to be improved. CONTENT OF THE INVENTION

[0004] In order to solve the problem of poor moisture-proof capability of the current battery shell, the application provides a new energy automobile battery shell.

[0005] The new energy automobile battery shell provided by the application adopts the following technical scheme:

[0006] The new energy automobile battery shell comprises a shell and a cover, the cover is rotationally arranged on the shell, the cover covers the opening of the shell, a containing cavity for mounting a battery is formed in the shell, a moisture-proof assembly is arranged in the containing cavity, the moisture-proof assembly comprises a blowing fan, a moisture-proof plate and a moisture-proof frame, the blowing fan is arranged outside the shell, the blowing fan is in communication with the containing cavity in the shell, a plurality of air outlets for air circulation are formed in the shell, the moisture-proof frame is arranged at the bottom of the containing cavity, and the moisture-proof plate is detachably connected to the moisture-proof frame.

[0007] Due to the poor moisture-proof ability of the current battery shell design, it is difficult to effectively isolate the intrusion of moisture and humidity, which can easily cause damage to the internal battery. By adopting the above technical solution, the shell and the shell cover are formed in the shell, and the moisture-proof assembly is installed in the accommodating cavity. The moisture-proof assembly is composed of a blowing fan, a moisture-proof plate and a moisture-proof frame. When the battery shell is in an environment with large temperature difference and needs to reduce the internal humidity, the blowing fan will start to blow the relatively dry air outside into the accommodating cavity. The dry air blown by the blowing fan will exchange with the internal humid air through the air outlets, thereby reducing the overall humidity. At the same time, the internal moisture-proof plate absorbs or blocks the water and moisture entering the shell, protecting the battery from moisture. By setting the moisture-proof assembly, the introduction of the blowing fan helps to improve the air circulation in the accommodating cavity to some extent, reducing the formation of condensed water. The moisture-proof plate has a moisture-absorbing or waterproof function, which can effectively absorb or block moisture, thereby reducing the accumulation of excessive humidity in the battery accommodating cavity, reducing the possibility of internal short circuit, corrosion or other damage caused by excessive humidity, and helping to prolong the service life of the battery, improve the durability and safety of the battery.

[0016] Optionally, a waterproof sealing ring for enhancing sealing is arranged at the opening of the shell, the waterproof sealing ring is arranged along the circumferential direction of the shell, and the cover body abuts against the surface of the waterproof sealing ring.

[0017] By adopting the technical scheme, the waterproof sealing ring is installed at the opening of the shell; through the setting of the waterproof sealing ring, the waterproof sealing ring can reduce the invasion of external moisture, humidity and other harmful liquids into the inside of the battery shell, form an effective waterproof barrier, ensure the dry environment inside the battery shell, help to reduce the dampness, corrosion or performance decline of the battery due to excessive humidity, and prolong the service life of the battery.

[0018] Optionally, an assembly groove for installing the waterproof sealing ring is formed on the shell, and the waterproof sealing ring is embedded in the assembly groove.

[0019] By adopting the technical scheme, the assembly groove is formed on the shell; through the setting of the assembly groove, the assembly groove provides an installation position for the waterproof sealing ring, ensures the accurate position of the waterproof sealing ring on the shell, reduces the displacement or inclination in the installation process, and helps to maintain the stability and reliability of the sealing ring.
