Description

Technical Field

[0001] The present invention relates to the technical field of battery boxes, and in particular to a battery box with high safety. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Among them, the energy required for pure electric vehicles is provided by batteries, and the batteries need to be installed in battery boxes to effectively protect the batteries.

[0003] After searching, it was found that the application number is CN202310803839.8, and the name is a battery box with high safety. The application proposes that the heat dissipation of the batteries inside the existing battery box generally adopts perforated heat dissipation. When this heat dissipation method is used in a humid environment, moisture will enter the battery box, which is easy to cause a short circuit in the internal batteries and even cause the batteries to burn, thereby reducing the safety during use. By passing cold air through a pipe to the concave channel, the cold air flowing in the concave channel will take out the heat on the cooling fins and finally discharge it through the exhaust hood, so as to achieve the heat dissipation inside the battery box. The closed heat dissipation not only ensures the heat dissipation effect of the battery body, but also avoids the entry of moisture, greatly improving the safety and service life of the battery body inside the battery box. At the same time, there is no need for a power source to drive it, and only the flowing air generated during the driving of the vehicle is required for heat dissipation, which is energy-saving and environmentally friendly, with low cost of use. At the same time, the spring three pairs of battery bodies The vibration received by the battery body is reduced to avoid damage to the battery body caused by vibration, which greatly improves the protection of the battery body. The friction between the piston and the cylinder and the obstruction of the gas in the cylinder during the descent of the piston can reduce the vibration received by the battery body, and then the battery body is again reduced in vibration, which greatly improves the protection of the battery body. The up and down movement of the piston during the vibration reduction process causes the flow of gas, which in turn causes the gas inside the battery case to flow, so that the heat dissipation effect of the heat dissipation fins is improved, thereby ensuring the heat dissipation effect of the battery case. However, when the application is in use, the distribution area of ​​the heat dissipation fins is small, the direct heat dissipation efficiency through the heat dissipation fins is low, and the spring shock absorption direction is single, and it is impossible to achieve all-round shock absorption, and the shock absorption effect is poor. At the same time, when the battery case collides, the spiral connecting wire used for connection cannot be quickly powered off, resulting in the battery being unable to be quickly powered off, and there is a risk of explosion and spontaneous combustion. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0005] 1. Technical issues to be resolved

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a battery box with high safety, which has the following beneficial effects:

[0018] (1) The present invention adopts heat dissipation fins, heat conducting plates, springs and sealing sleeves. The sealing sleeves are made of high-temperature resistant rubber material. The heat dissipation fins penetrate the sealing sleeves and slide against the sealing sleeves. The sealing sleeves play a sealing role and provide damping by abutting against the heat dissipation fins using friction. The battery body abuts against the heat conducting plate and is installed inside the box. When vibration occurs, the spring deforms and compresses to reduce shock. The heat dissipation fins enter and exit the box, and damping is generated by friction to avoid repeated bouncing of the spring, thereby improving the stability of shock absorption. At the same time, the heat dissipation fins are distributed in six directions of the box, providing shock absorption in all directions, making the shock absorption more comprehensive and more effective. In addition, the heat dissipation fins have a large distribution area and a better heat dissipation effect.

When the box body is severely squeezed and deformed laterally, the displacement of the battery body becomes significantly larger, and the connecting wire can be squeezed and contacted with the cutting edge. The cutting edge can cut off the connecting wire, thereby cutting off the power supply to the battery body, avoiding explosion and combustion caused by untimely power off, and improving the safety of use.
