[0002] With the rapid development of the electric vehicle market, battery performance in low-temperature environments has become a key factor restricting the driving range and lifespan of electric vehicles. In low-temperature environments, the internal resistance of the battery increases, leading to a decrease in battery discharge capacity, slower charging speed, and even potential battery damage. Automotive battery heating films are electrically heated materials installed on the battery casing, typically made of materials such as polyimide, polyamide, and fluoroplastics. They aim to improve battery efficiency and lifespan by heating the battery, while also preventing performance degradation and damage in low-temperature environments.

[0003] Traditional automotive power lithium battery heating films are not convenient to install and maintain, requiring a lot of time and manpower for replacement or repair. They also have low heat transfer efficiency, resulting in uneven heating of the battery and affecting the heating effect. Utility Model Content

[0019] The technical scheme in the utility model embodiments will be apparently and completely described below with the drawings in the utility model embodiments, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative efforts fall within the scope of the utility model.

[0020] Please refer to Figures 1-6This utility model provides a technical solution: a heating film assembly for an automotive power lithium battery, including an outer frame 1. Two limiting sides 11 are fixedly provided at both ends of the outer frame 1. A top heat-conducting plate 7 and a bottom heat-conducting plate 8 are respectively bonded to the top and bottom of the outer frame 1. These two heat-conducting plates are key components for heat transfer. They evenly transfer the heat generated by the battery heating film 6 to the battery, ensuring that the battery can work normally in low-temperature environments. A mounting frame 2 is movably connected to the front side of the outer frame 1. The battery heating film 6 is bonded and fixed inside the mounting frame 2. The battery heating film 6 is the core component of the assembly and is responsible for generating heat to heat the battery. It is bonded inside the mounting frame 2 to ensure that the heat can be directly transferred to the battery. Mounting grooves are opened on the rear side of both ends of the top of the outer frame 1. A pin 5 is fixedly provided in the mounting groove. A cover plate 10 is fixedly installed on the top of the mounting groove by screws. The cover plate 10 is used to cover the mounting groove, protect the pin 5 from interference and damage from the external environment, and enhance the aesthetics of the entire assembly.

[0021] The front end of the outer frame 1 is designed with an open shape. The outer frame 1 not only protects the internal battery heating film 6 and heat conduction plate, but also provides precise positioning and support for the mounting frame 2 through the limiting side 11 on it. The front side of the mounting frame 2 is fixedly provided with a handle 3, which makes it easy to pick up and disassemble the mounting frame 2.

[0022] The front side of the mounting frame 2 has several wire holes 4, and the two ends of the mounting frame 2 are respectively located between two parallel limiting sides 11.

[0023] The two ends of the pin 5 extend through the outer wall and inner wall of the outer frame 1, respectively. The outer frame 1 and the mounting frame 2 are provided with slots 9 that match the pin 5 on both sides. This pair of structures realizes quick connection and fixation between the mounting frame 2 and the outer frame 1. The pin 5 can be easily extended and retracted, so that the mounting frame 2 can be easily installed and disassembled.

[0024] The top heat-conducting plate 7 and the bottom heat-conducting plate 8 are tightly fitted to the limiting side 11 on opposite sides. The limiting side 11 ensures the stability and accuracy of the mounting frame 2 during installation, preventing it from shifting or shaking. At the same time, the tight fit with the top heat-conducting plate 7 and the bottom heat-conducting plate 8 enhances the heat conduction effect.

[0025] During installation, insert the rear end of the mounting frame 2 into the gap between the two limiting sides 11. Pull the handle on the outside of the pin 5 to retract the other end of the pin 5 into the slot 9. After the rear end of the mounting frame 2 is in place, release the handle. At this time, the limiting end of the pin 5 will be inserted into the slot 9 on the mounting frame 2 to limit its position.
