[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0035] It should be noted that if the utility model embodiment involves directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0037] Please refer to the instruction manual appendix. Figures 1-6 This utility model provides a battery protection box for new energy vehicles, including a box body 1. The box body 1 has a sturdy cuboid structure and good protective performance, which can effectively protect the internal battery from external impacts and damage.

[0038] A base support assembly 2 is installed at the bottom of the housing 1 to directly support the battery. The base support assembly 2 includes a base plate 21 that completely covers the bottom surface of the housing 1. The base plate 21 is hollow and open from front to back, forming an air circulation channel. Strip-shaped air vents 12 are provided on both the front and rear walls of the housing 1, and these vents are connected to the hollow structure of the base plate 21, thus providing a path for air to enter and exit. Several longitudinally distributed heat dissipation fins 22 are evenly distributed inside the base plate 21. These heat dissipation fins 22 greatly increase the heat dissipation area, quickly conduct away the heat generated by the battery, improve heat dissipation efficiency, ensure the battery operates in a suitable temperature environment, extend battery life, and ensure stable performance.

[0039] A switch assembly 6 is installed inside the front and rear walls of the enclosure 1 to respectively close the front and rear strip-shaped air vents 12. The specific structure of the switch assembly 6 is as follows: a strip-shaped baffle plate 62 is correspondingly engaged inside the top hole wall of the front and rear strip-shaped air vents 12. The strip-shaped baffle plate 62 fits tightly with the strip-shaped air vents 12, effectively blocking airflow. A stepping cylinder 61 is installed at the center of the front and rear walls of the enclosure 1. Through the precise control of the stepping cylinder 61, the front and rear strip-shaped baffle plates 62 can be driven down to block the corresponding strip-shaped air vents 12, realizing flexible adjustment of the airflow state so as to control the heat dissipation effect according to actual needs.

[0040] The bottom of the enclosure 1 is secured with a bottom protective plate 4 by four corner screws 5, ensuring the bottom protective plate 4 is firmly installed. Anti-misalignment posts 41 are located at the center of the front, back, left, and right edges of the top of the bottom protective plate 4, and anti-misalignment holes 11 are located at the center of the front, back, left, and right edges of the bottom of the enclosure 1. The four anti-misalignment posts 41 are inserted into the four anti-misalignment holes 11. This anti-misalignment design prevents installation errors and ensures the accuracy and reliability of the installation. The bottom surface of the bottom protective plate 4 is coated with an anti-scratch coating 42, which effectively prevents the bottom protective plate 4 from being scratched and damaged during use, maintaining its appearance and performance.
