[0002] The vehicle reducer is a key component in the automotive transmission system. Its main function is to reduce the engine's output speed while increasing torque output to meet the vehicle's power demands under different driving conditions. The reducer is usually located between the engine and the drive wheels, closely connected to the transmission, and sometimes even integrated inside the transmission. During vehicle operation, the reducer uses its internal gear set to reduce speed and increase torque, enabling the vehicle to maintain stable power output when climbing hills, carrying heavy loads, or in complex road conditions. The core components of the reducer include gears, bearings, and housings. The precision manufacturing and assembly of these components ensure the reducer's efficiency and reliability.

[0003] Based on existing vehicle reducers, it has been found that vehicle reducers are located near the vehicle engine. During vehicle operation, vehicle reducers are often in a high-temperature state, especially during continuous use or high-load operation, which can cause overheating, affecting their normal operation and lifespan.

[0004] Based on this, the present invention designs a vehicle reducer safety protection device to solve the above problems. Utility Model Content

The cooling mechanism includes a first copper pipe, a liquid delivery pipe, and a second copper pipe. The first copper pipe is disposed between the low-speed shaft and the reducer body, and is attached to the outer wall of the reducer body. A liquid delivery pipe is fixedly connected to the right end of the first copper pipe, and a second copper pipe is fixedly connected to the end of the liquid delivery pipe away from the first copper pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a refrigeration mechanism is provided. When the liquid pump body is started, the coolant circulates in the first copper pipe and the second copper pipe, which not only ensures the continuity and stability of cooling, but also reduces maintenance costs and resource consumption due to the circulation of coolant. In addition, the design of the refrigeration mechanism enables the coolant to accurately cover the key hot areas of the reducer body, further improving the cooling efficiency, effectively preventing the reducer body from overheating, extending the service life of the reducer, and improving its working performance.

[0016] 2. This utility model includes an air guiding mechanism that utilizes the under-airflow generated during vehicle operation to guide high-speed airflow to the first and second jet pipes via the fan body and air guiding pipes. This directly cools the low-speed shaft and key components of the cooling mechanism. The beneficial effects of this design are manifested in several aspects: First, it requires no additional energy input, i.e., energy-free cooling, reducing the consumption of electricity or fuel by utilizing the vehicle's existing airflow resources. Second, the protective net design ensures the cleanliness of the airflow, preventing dust and other debris from damaging the cooling system. Finally, with the help of the air guiding mechanism, the temperature of the coolant in the cooling mechanism can be quickly reduced, ensuring cooling efficiency and thus improving the overall cooling performance of the reducer.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-8 In this embodiment of the present invention, a vehicle reducer safety protection device includes a reducer body 1. A low-speed shaft 2 is installed at the front end of the reducer body 1, and a high-speed shaft 3 is installed at the rear end of the reducer body 1. A cooling mechanism 4 is provided on the outer side of both the low-speed shaft 2 and the high-speed shaft 3. A venting mechanism 5 is provided below the cooling mechanism 4. The cooling mechanism 4 includes a first copper pipe 406, a liquid inlet pipe 407, and a second copper pipe 408. The first copper pipe 406 is provided between the low-speed shaft 2 and the reducer body 1. The first copper pipe 406 is attached to the outer wall of the reducer body 1. The right end of the first copper pipe 406 is fixedly connected to the liquid inlet pipe 407, which is located away from the first copper pipe 408. One end of a copper tube 406 is fixedly connected to a second copper tube 408. The refrigeration mechanism 4 also includes a liquid outlet pipe 405. The lower end of the first copper tube 406 is fixedly connected to the liquid outlet pipe 405. The lower end of the liquid outlet pipe 405 is fixedly connected to a liquid pump body 404. The right end of the liquid pump body 404 is fixedly connected to a liquid extraction pipe 403. The right end of the liquid extraction pipe 403 is fixedly connected to a coolant tank 401. An aluminum sheet 402 is fixedly installed on the outer wall of the coolant tank 401. Multiple aluminum sheets 402 are distributed from front to back on the coolant tank 401. The upper end of the coolant tank 401 is fixedly connected to a drain pipe 409. The drain pipe 409 is connected to the second copper tube 408.

[0030] See Figure 3 , Figure 7 and Figure 8Initially, before activation, the liquid pump body 404 needs to be powered on and connected to the control terminal. When activated, the liquid pump body 404 is started to draw coolant from the coolant tank 401 through the liquid drawing pipe 403, and then transport it to the first copper pipe 406 through the liquid outlet pipe 405. The coolant is continuously filled into the first copper pipe 406 and the second copper pipe 408. The low temperature is transferred to the reducer body 1 through the first copper pipe 406 and the second copper pipe 408, thereby achieving the effect of cooling the reducer body 1. When the coolant passes through the second copper pipe 408, it will return to the coolant tank 401 through the liquid drain pipe 409, thus achieving the effect of circulating the coolant.

[0031] The refrigeration mechanism 4 uses high-efficiency heat-conducting materials and a circulating cooling structure, and is used in conjunction with the energy-free cooling structure of the air guiding mechanism 5 to achieve energy-saving cooling effect without the need for additional power or fuel consumption. Furthermore, the first copper pipe 406, the liquid delivery pipe 407, and the second copper pipe 408 in the refrigeration mechanism 4 provide precise cooling to the reducer body 1, which can effectively reduce the temperature of the reducer body 1 and effectively achieve the cooling effect of the reducer body 1, thus preventing the reducer body 1 from overheating.

[0032] The air guiding mechanism 5 includes a first jet pipe 506 and a second jet pipe 507. The first jet pipe 506 is located below the low-speed shaft 2, and the second jet pipe 507 is located behind the first jet pipe 506. The air guiding mechanism 5 also includes a connecting pipe 504. The lower ends of the first jet pipe 506 and the second jet pipe 507 are fixedly connected to the connecting pipe 504. The rear end of the connecting pipe 504 is fixedly installed with a support frame 505. The support frame 505 is fixedly installed at the lower end of the reducer body 1. The lower end of the connecting pipe 504 is fixedly connected to the air guiding pipe 501. The lower end of the air guiding pipe 501 is equipped with a fan body 502. A protective net 503 is provided on the left side of the fan body 502.

[0033] See Figure 3 , Figure 5 and Figure 7Initially, during operation, the air duct 501 extends to the vehicle chassis. As the vehicle moves, high-speed airflow continuously passes through the chassis and enters the air duct 501. The protective net 503 acts as a barrier, filtering dust and other debris. Multiple fans 502 require power. The user can control the terminal to start the fans 502 to deliver air into the air duct 501. The airflow will reach the first jet pipe 506 and the second jet pipe 507 through the air duct 501. The airflow in the first jet pipe 506 directly blows onto the outside of the low-speed shaft 2, effectively reducing the temperature on the low-speed shaft 2. The airflow in the second jet pipe 507 directly blows onto the coolant tank 401 and aluminum sheet 402 of the refrigeration mechanism 4, thereby quickly reducing the temperature of the coolant in the coolant tank 401. This ensures that the refrigeration mechanism 4 can circulate low-temperature coolant, achieving the effect of quickly cooling the reducer body 1.

[0034] Among them, the air guiding mechanism 5 is an air guiding structure, and the air guiding pipe 501 extends to the vehicle chassis. During the vehicle's operation, a large amount of airflow will flow into the area under the vehicle chassis. The air guiding pipe 501 can absorb a large amount of high-speed airflow and use this airflow for cooling operations, effectively reducing the load on the vehicle's cooling system and effectively reducing the vehicle's electricity or fuel consumption.

[0035] The working principle of this utility model is as follows: When the vehicle reducer starts working, the liquid pump body 404 in the refrigeration mechanism 4 first draws coolant from the coolant tank 401 through the liquid extraction pipe 403, and then delivers the coolant to the first copper pipe 406 through the liquid outlet pipe 405. The coolant circulates in the first copper pipe 406 and the second copper pipe 408, transferring the low temperature to the reducer body 1, thereby achieving a cooling effect. During this process, the first copper pipe 406 is attached to the outer wall of the reducer body 1 to ensure precise cooling. At the same time, the air guide mechanism 5 starts working, and the fan body 502 draws in high-speed airflow from under the vehicle chassis, which is transmitted to the first jet pipe 506 and the second jet pipe 507 through the air guide pipe 501. The airflow from the first jet pipe 506 directly blows onto the outside of the low-speed shaft 2, reducing its temperature; the airflow from the second jet pipe 507 blows onto the coolant tank. On 401 and aluminum fins 402, the cooling speed of the coolant is accelerated. The aluminum fins 402 are distributed on the coolant tank 401, which helps to improve the heat dissipation efficiency of the coolant. During this process, the protective net 503 plays a blocking role, filtering out dust and other impurities to ensure the cleanliness of the airflow. After passing through the second copper pipe 408, the coolant returns to the coolant tank 401 through the drain pipe 409, realizing recycling. The entire device adopts high-efficiency heat-conducting materials and a circulating cooling structure, combined with the energy-saving cooling air guide mechanism 5, to achieve energy-saving cooling effect, reduce the load on the vehicle cooling system, and reduce power or fuel consumption. In summary, this vehicle reducer safety protection device, through the synergistic action of the cooling mechanism 4 and the air guide mechanism 5, accurately and efficiently cools the reducer body 1, solves the problem of overheating of the vehicle reducer in high-temperature environments, and improves the service life and safety of the vehicle.
