Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a high-strength and impact-resistant new energy vehicle battery box. Background Art

[0002] New energy vehicles have developed rapidly in recent years and have occupied a large proportion in the automotive field. The essence of new energy is to replace oil consumption with electricity consumption, thereby greatly reducing the large amount of exhaust gas generated during oil consumption. New energy vehicles need to have a box specifically for installing the power core, that is, the battery. The battery inside the box is relatively fragile and cannot be guaranteed to be safe when impacted. A high-strength and impact-resistant new energy vehicle battery box is required.

[0003] The existing patent with announcement number CN220569806U, named "A high-strength and impact-resistant new energy vehicle battery box", the utility model provides a high-strength and impact-resistant new energy vehicle battery box, including a battery box body, the outer surface of the battery box body is sleeved with a rectangular impact-resistant steel frame, the rectangular impact-resistant steel frame and the surface of the battery box body are provided with a first fixing hole, the rectangular impact-resistant steel frame is fixedly connected to the battery box body through a first fastener penetrating the first fixing hole, and the battery box body is provided with a mounting filter plate. The utility model sets a rectangular impact-resistant steel plate, so that when the battery box body is in use, the staff sleeves the rectangular impact-resistant steel frame to the outside of the battery box body, thereby greatly improving the impact resistance of the battery box body under the action of the rectangular impact-resistant steel frame, thereby facilitating the protection of the internal battery, and fixing the rectangular impact-resistant steel frame to the battery box body by fasteners, thereby facilitating the disassembly of the rectangular impact-resistant steel frame and facilitating its recycling and reuse.

[0004] The above-mentioned device greatly improves the impact resistance of the battery box body by sleeve-joining a rectangular impact-resistant steel frame onto the outside of the battery box body, thereby facilitating the protection of the internal batteries. However, the internal batteries are still rigidly connected to the battery box, and the impact on the internal batteries will not be reduced when impacted, which cannot meet people's usage needs well. In view of the above situation, technical innovation is carried out on the basis of the existing battery box. Utility Model Content

[0011] Furthermore, a mounting frame is provided on the right side of the circulating pump, and a heat dissipation copper tube is installed inside the mounting frame. The tube wall of the heat dissipation copper tube is relatively thin, and the mounting frame prevents the heat dissipation copper tube from being deformed by external force.

[0012] Furthermore, a heat dissipation fan is installed on the right side of the installation frame, and the heat dissipation fan and the heat dissipation copper tube are welded.

[0015] 1. The utility model places the battery pack between the lower mounting frame and the upper mounting frame, rotates the nut to connect and tighten the threaded rod and the connecting rod, and the upper mounting frame and the lower mounting frame clamp the battery pack to install stably. When it is impacted, the spring rods in all directions reduce the vibration amplitude of the battery pack to avoid direct force on the battery pack. At the same time, the outer shell and the reinforcing ribs are superimposed to improve the strength, and the anti-puncture layer reduces the probability of internal damage caused by local puncture, thereby protecting the safety and stability of the battery pack;

[0016] 2. When the battery pack of the utility model is working, the heat of each battery is absorbed by the heat-conducting copper plate into the pipeline. The coolant in the pipeline carries the heat and runs through the connecting pipe and the circulation pump to the inside of the heat dissipation copper tube in the installation frame. The heat dissipation copper tube has a large contact area with the air, which is convenient for dissipating heat through the heat dissipation fan. The dustproof net prevents dust from entering the device from the heat dissipation fan, effectively reducing the temperature of the battery pack during operation and improving safety.
