[0026] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figures 1-6 As shown, this utility model provides an integrated thermal control and protection device for an electric drive axle resistant to extreme weather conditions. It includes an electric drive axle body 1, a protective frame 2, and two movable blocks 7. The bottom of the protective frame 2 has multiple ventilation holes 3. A fan 4 is fixedly installed on the bottom inner wall of the protective frame 2. A forward / reverse motor 5 is fixedly installed on the bottom of the protective frame 2. A threaded rod 6 is fixedly installed on one side of the outer wall of the forward / reverse motor 5. The inner surface of one of the movable blocks 7 is threadedly connected to the outer surface of the threaded rod 6. A strip plate 8 is fixedly installed on the bottom of the protective frame 2, and the outer surface of the threaded rod 6 is movably inserted into the strip plate 8. Inside the protective frame 2, a fixed plate 9 is fixedly installed at the bottom. A guide rod 10 is fixedly installed on one side of the outer wall of the fixed plate 9. The outer wall of another movable block 7 is movably fitted onto the outer wall of the guide rod 10. A sealing plate 11 is fixedly installed between the bottoms of the two movable blocks 7. The top of the sealing plate 11 is in contact with the bottom of the protective frame 2. A strip column 12 is fixedly installed at the bottom of the protective frame 2. A strip-shaped insertion hole 13 is opened on one side of the outer wall of the strip column 12. An insertion strip 14 is fixedly installed on one side of the outer wall of the sealing plate 11. The outer wall of the insertion strip 14 is movably inserted into the inside of the strip-shaped insertion hole 13.

[0029] The overall effect of Embodiment 1 is that when the electric drive axle is used in a low-temperature environment, the fan 4 installed at the bottom of the inner wall of the protective frame 2 is started by the controller 20. At the same time, the forward and reverse motors 5 installed at the bottom of the protective frame 2 are also started by the controller 20, which drives the threaded rod 6 to rotate inside the strip plate 8. Since a guide rod 10 is installed between the strip plate 8 and the fixed plate 9, one moving block 7 is movably sleeved on the guide rod 10, and another moving block 7 is threadedly connected to the threaded rod 6. A sealing plate 11 is installed between the bottoms of the two moving blocks 7. Thus, by rotating the threaded rod 6 inside the strip plate 8, the two moving blocks 7 and the sealing plate 11 can be moved, and the sealing plate 11 can be moved to one side along the bottom of the protective frame 2 until the multiple ventilation holes 3 opened at the bottom of the inner wall of the protective frame 2 are exposed, so that the internal fan 4 can... Airflow is created between the main body and the outside environment, thereby cooling the internal components of the electric drive axle body 1. Then, when the electric drive axle body 1 is working in a high-temperature environment, the sealing plate 11 is moved by the above operation until the insert 14 installed on one side of the outer wall of the sealing plate 11 is precisely inserted into the strip-shaped insertion hole 13 opened on one side of the outer wall of the strip column 12, and the sealing plate 11 precisely covers multiple ventilation holes 3. Then, the internal heater 18 is activated by the controller 20, and in cooperation with the temperature sensor 19, the internal temperature is heated to the optimal temperature to achieve a temperature control effect. This avoids affecting the working efficiency of the internal equipment in a low-temperature environment and ensures that all components in the electric drive axle can work normally, thereby improving the service life of the electric drive axle and improving the performance of the integrated thermal control and protection device for the electric drive axle that is resistant to extreme climates.

[0030] Example 2: As Figures 2-6 As shown, a protective cover 15 is fixedly installed at the bottom of the protective frame 2. Multiple heat dissipation holes 16 are opened on one side of the outer wall of the protective cover 15. Two shelves 17 are fixedly installed on the inner surface of the protective frame 2. A heater 18 is fixedly installed on the top of one shelf 17. A temperature sensor 19 is fixedly installed on one side of the inner wall of the protective frame 2. A controller 20 is fixedly installed on one side of the outer wall of the protective frame 2, and the outer side of the controller 20 is electrically connected to the outer surface of the forward and reverse motor 5. A cover plate 21 is fixedly installed on the top of the protective frame 2. A mudguard 22 is fixedly installed at the bottom of the protective cover 15, and the top of the mudguard 22 is fixedly connected to the top of the strip plate 8.

[0031] The overall effect of embodiment 2 is as follows: the electric drive axle body 1 is installed on two layers 17 inside the protective frame 2, which provides protection against damage from foreign objects and improves the service life of the electric drive axle body 1 and its internal components. Secondly, a protective cover 15 is installed at the bottom of the protective frame 2. The protective cover 15 is located around the forward and reverse motors 5. Through the action of the protective cover 15, it effectively prevents foreign objects from damaging the forward and reverse motors 5 and improves the service life of the forward and reverse motors 5. Furthermore, because a mudguard 22 is installed between the protective cover 15 and the bottom of the strip plate 8, it can prevent foreign objects from being directly adsorbed onto the threaded rod 6 and the guide rod 10, ensuring the smooth movement of the sealing plate 11. Moreover, because multiple heat dissipation holes 16 are opened on one side of the outer wall of the protective cover 15, the heat generated by the forward and reverse motors 5 during operation can be dissipated through the multiple heat dissipation holes 16, improving the performance of the integrated thermal control and protection device for the electric drive axle.

[0032] Working principle: First, when the electric drive axle body 1 is used in a low-temperature environment, the sealing plate 11 just covers multiple ventilation holes 3. Then, the heater 18 is activated by the controller 20 to heat the inside of the protective frame 2. Under the action of the temperature sensor 19, the inside of the protective frame 2 and the surrounding area of ​​the electric drive axle body 1 are heated to the optimal temperature to avoid affecting the working performance of the electric drive axle in a low-temperature environment. Then, when the electric drive axle body 1 is used in a high-temperature environment, the forward and reverse motors 5 are activated by the controller 20. Since the two moving blocks 7 are respectively threadedly connected to the threaded rod 6 and movably sleeved on the guide rod 10, they can drive the two moving blocks 7. The sealing plate 11 moves along the bottom of the protective frame 2 until multiple ventilation holes 3 are exposed. At this time, the fan 4 is started by the controller 20. Under the action of multiple ventilation holes 3, air can be formed with the outside, and heat can be dissipated from the components inside the electric drive bridge body 1, achieving a cooling effect. This allows it to maintain normal operation in high or low temperature environments. Furthermore, the protective frame 2 provides protection for the electric drive bridge body 1, effectively preventing foreign objects from directly damaging it during use, thus improving the service life of the electric drive bridge. In general, this improves the effectiveness of the integrated thermal control and protection device for the electric drive bridge that is resistant to extreme weather conditions.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
