A pulling rod 10 is fixedly connected to the outer bottom of the movable rod 8, and the pulling rod 10 is used to pull the movable rod 8. The outside of the pulling rod 10 is slidably connected to a fixed plate 11, and a square groove 12 is provided inside the fixed plate 11, and the fixed plate 11 provides a motion track for the pulling rod 10. The rear side of the movable rod 8 is fixedly connected to a limit block 13, and the limit block 13 is used to limit the range of motion of the movable rod 8. A plurality of circular grooves 14 are provided inside the four corners of the frame 2, and the circular grooves 14 provide sliding space. An L-shaped plate 15 is fixedly connected to the right side of the outer shell 1, and the L-shaped plate 15 is used to fix other components. A plurality of T-shaped slots 16 are provided inside the outer shell 1, and the T-shaped slots 16 are used to fix and install other components. A plurality of shock-absorbing components are fixedly connected to the outside of the frame 2, which are used to reduce vibration and noise and improve system stability and comfort. The outside of the movable rod 8 is slidably connected to the inside of the L-shaped plate 15, and the movable rod 8 slides inside the L-shaped plate 15 to be locked.

[0032] Reference Figure 4 , multiple shock-absorbing components include a fixed column 17, which is used to support and fix the entire structure to stabilize the installation position of the air-conditioning evaporator. The outside of the fixed column 17 is respectively sleeved with a spring 18, which is used to absorb and mitigate external impact and vibration, thereby protecting the internal components of the evaporator and enhancing the overall seismic resistance. A hollow column 19 is arranged outside the spring 18, and the hollow column 19 plays the role of supporting and fixing the spring. The outside of the hollow column 19 is respectively fixedly connected to a limit ring 20, and the function of the limit ring 20 is to limit the movement range of the hollow column 19 to ensure that the shock-absorbing component works effectively within the designed position. The front end of the hollow column 19 is fixedly connected to a circular plate 21, and the circular plate 21 is used to increase the stability of the fixed point.

[0033] Reference Figure 2 , Figure 3 , Figure 4, the left side of the two circular rings 7 is fixedly connected to the right side of the fixed block 6, and the circular rings 7 and the fixed block 6 are fixed by welding. The bottom ends of the two circular rings 7 are fixedly connected to the top of the fixed plate 11, and the circular rings 7 and the fixed plate 11 are fixed by welding. The front and rear sides of the fixed block 6 are in contact with the front and rear inner walls of the housing 1, and the fixed block 6 is used to support other components or provide structural stability.

[0034] Working principle: during installation, align the circular plate 21 with the T-slot 16 and then push the frame 2 into the interior of the housing 1. Then the L-shaped plate 15 will squeeze the movable rod 8, causing the movable rod 8 to move backward. The movable rod 8 moves backward with the pulling rod 10, and the pulling rod 10 compresses the spring 9. When the movable rod 8 slides to the inside of the L-shaped plate 15, the spring 9 provides a restoring force to fix the frame 2 inside the housing 1, ensuring that the evaporator is firmly connected to the installation position of the vehicle to avoid loosening or movement during driving. A stable installation ensures that the evaporator effectively transfers heat during operation and maintains the performance and efficiency of the air-conditioning system, which is crucial to the driving comfort and fuel economy of the vehicle.

[0035] During the movement of the car, there will be bumps and vibrations, which will cause the circular plate 21 to slide inside the circular groove 14 with the stop ring 20. The circular plate 21 compresses the spring 2 18 to reduce the impact of bumps and vibrations on the frame 2, effectively improving the stability and service life of the automobile air-conditioning evaporator, while reducing the interference of vibration and noise to the driver and passengers, extending the service life of the evaporator and reducing maintenance costs. By reducing the impact of external vibrations, various components of the air-conditioning system, including the evaporator, can operate more efficiently. This helps to maintain the high efficiency and normal operation of the air-conditioning system.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
