[0002] With the improvement of people's living standards and social production technology, electric vehicles have become a daily necessity. People's demands for electric vehicle functionality are also increasing. Some electric vehicles on the market generally have a range of 20-50 kilometers, making them suitable only for short-distance travel. As the electric vehicle market continues to pursue longer range, users want to be able to install different battery models and quantities according to different usage scenarios and needs. However, existing electric vehicle battery compartments are mostly fixed installation spaces, making it difficult to accommodate the installation requirements of different battery packs when batteries need to be replaced or upgraded. This limitation may also force manufacturers to design and use multiple different frames to accommodate different battery pack installation requirements, increasing production costs. Furthermore, the battery pack anti-theft design of many electric vehicles currently relies mainly on a closed cover structure. Although the cover can protect the battery pack to a certain extent, its protection is often insufficient to withstand damage with specialized tools. Many thieves can easily access the battery by prying, cutting, or damaging the cover, resulting in significant property losses for electric vehicle users. Therefore, the present utility model provides a high-durability electric vehicle to address the problems raised in the above background technology. Utility Model Content

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] Reference Figure 1-6 The embodiment of the utility model is a high-durability electric vehicle, which includes a frame 1. The frame 1 is made of high-strength special steel pipes to improve the load-bearing strength and fatigue resistance of the vehicle body. A fixed plate 2 is fixedly connected to the inner side of the frame 1, and a second bottom plate 6 is fixedly connected to one side of the fixed plate 2. A movable plate 3 arranged opposite to the fixed plate 2 is installed on the inner side of the frame 1. A support plate 4 with an L-shaped structure is fixedly connected to the top of the movable plate 3. The side of the support plate 4 close to the second bottom plate 6 is fixedly connected to the first bottom plate 5. The first bottom plate 5 is slidably connected to the top side of the second bottom plate 6, and a plurality of battery packs 7 are installed together on the top of the first bottom plate 5 and the second bottom plate 6. The battery pack 7 uses lithium-ion batteries with high energy density and long cycle life as the power source. A cover 8 is installed together on the top of the fixed plate 2 and the movable plate 3;

[0026] The first base plate 5 and the second base plate 6 can form a stable support structure for installing the battery pack 7, and the first base plate 5 and the second base plate 6 are slidably connected.

[0031] Working Principle: The first and second base plates 5, 6 form a stable support structure for mounting the battery pack 7. The first and second base plates 5, 6 are slidably connected, allowing the first base plate 5 to be moved to adjust the support area of ​​the first and second base plates 5, 6, thereby facilitating the requirements of different battery configurations and helping to reduce production costs and complexity.

[0032] When the cover 8 is illegally opened, the connecting rod 14 will trigger the micro switch 16, and the micro switch 16 is electrically connected to the alarm system of the entire vehicle, thereby triggering the alarm system to sound an alarm, which is beneficial to improving the safety of the electric vehicle.
