Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a modified engine tail cover structure with adjustable ventilation. Background Technology

[0002] The engine tail cover is an important component of a vehicle. The existing engine tail cover structure is a fixed design. This fixed structure can meet the needs when the vehicle is traveling at low speeds, but when the vehicle is traveling at high speeds, the airflow around the vehicle body will change in a complex way. The fixed tail cover structure cannot effectively guide or utilize the airflow according to the real-time wind speed, which will lead to insufficient downforce or instability when the vehicle is traveling at high speeds, affecting driving safety.

[0003] In addition, the engines of modified or high-performance vehicles generate a lot of heat when running under high load. Traditional engine tail covers only have passive heat dissipation holes, or adopt a closed design for aesthetic purposes, which makes it difficult for hot air in the engine compartment to be expelled quickly, resulting in heat accumulation and affecting engine performance and service life.

[0004] Although some existing heat dissipation structures are equipped with heat dissipation holes, they lack active ventilation devices, resulting in low heat dissipation efficiency. At the same time, the simple opening design cannot prevent hot air from flowing back into the engine compartment, further reducing the heat dissipation effect. In non-heat dissipation states, external rainwater or foreign objects can also enter the interior through the heat dissipation holes, causing damage to components.

[0005] Therefore, this utility model proposes a modified engine tail cover structure with adjustable ventilation to address the shortcomings of the prior art. Utility Model Content

The heat dissipation mechanism 2 also includes a fan 205. The motor 203 drives the fan 205 to rotate through the transmission column 204. The fan 205 is driven by the motor 203. The transmission column 204 is used to transmit the power of the motor 203. The fan 205 is used to generate airflow. The cover 1 has a heat dissipation hole 201, which is used to exhaust hot air.

[0031] Please refer to Figure 1 , Figure 3 and Figure 5The basic frame of the automatic airflow adjustment mechanism is formed by a through groove 3 opened in the inner wall of the cover 1. A rotating groove 4 is opened in the inner wall of the through groove 3, and a rotating column 5 is rotatably connected to the inner wall of the rotating groove 4.

[0033] As a preferred embodiment, please refer to Figure 4 A transmission column 204 is provided between the motor 203 and the fan 205.

[0035] As another preferred embodiment, to prevent foreign objects from entering and damaging internal components, please refer to... Figure 1 A hinge 207 and a protective cover 208 are installed at the outlet of the heat dissipation hole 201. The protective cover 208 is rotatably connected to the edge of the heat dissipation hole 201 via the hinge 207. The hinge 207 provides a rotation shaft for the protective cover 208, so that the protective cover 208 can be flipped open or closed to seal the heat dissipation hole 201.

[0036] As another preferred embodiment, please refer to Figure 1 The bottom of the wind deflector 6 is fixedly connected to a rotating column 5. The rotating column 5 is rotatably connected to the rotating groove 4 on the inner wall of the through groove 3 as a rotating shaft. The wind deflector 6 rotates around the axis of the rotating column 5.

[0037] As another preferred embodiment, please refer to Figure 3 A sliding post 10 is fixedly connected to the right side of the sliding plate 8. The sliding post 10 is preferably integrally formed on the side wall of the sliding plate 8. The sliding post 10 is used to insert into the sliding groove 9 on the inner wall of the cover 1.

[0038] As another preferred embodiment, in order to construct a stable reset structure, please refer to... Figure 5 The bottom of the spring 11 is fixedly connected to a sliding plate 12, and the top of the spring 11 abuts against the bottom of the sliding plate 18. The sliding plate 12 serves as the lower support of the spring 11.

[0039] As another preferred embodiment, to achieve precise guide positioning, please refer to... Figure 3 The outer wall of the sliding column 10 slides along the inner wall of the sliding groove 9. The shape of the inner wall of the sliding groove 9 matches the shape of the outer wall of the sliding column 10. The sliding column 10 and the sliding groove 9 form a sliding fit, which ensures the stability of the sliding plate 8 during the pressing process.

[0040] As another preferred embodiment, please refer to Figure 5 The sliding plate 12 slides along the inner wall of the sliding groove 13, which is located on the inner wall of the cover 1. The outer contour of the sliding plate 12 slides in conjunction with the inner wall of the sliding groove 13 to prevent the spring 11 from tilting laterally when compressed or rebounding.

[0041] Working principle:

[0042] When the vehicle is in motion, the wind force pushes the wind deflector 6 downwards due to high wind speed. A rotating column 5 is fixedly connected to the bottom of the wind deflector 6. The rotating column 5 is rotatably connected to a rotating groove 4 opened on the inner wall of the through groove 3, causing the wind deflector 6 to rotate around the rotating column 5. The wind deflector 6, through the rotating column 7, causes the sliding plate 8 to press downwards, thus widening the opening of the through groove 3 and increasing the downward pressure on the vehicle. Simultaneously, the outer wall of the sliding column 10 fixedly connected to the right side of the sliding plate 8 slides along the inner wall of the sliding groove 9 opened on the inner wall of the cover 1. At the same time, the sliding plate 8 presses down on the spring 11 at the bottom. The bottom of the spring 11 is fixedly connected to the sliding plate 12. The sliding plate 12 will slide along the inner wall of the sliding groove 13 opened on the inner wall of the cover 1. The double guidance of the sliding groove 9 and the sliding groove 13 prevents the device from shaking and becoming unstable when it is pressed down. When the wind speed is not high, the rebound force of the spring 11 can push the sliding plate 12, the sliding plate 8 and the wind deflector 6 to reset, so that the vehicle can also be used in daily life. Through the coordinated action of the automatic air volume adjustment mechanism, the problem of unstable pressure causing driving safety when the vehicle is driving at high speed is solved.

[0043] When the engine overheats and needs to dissipate heat, the cooling mechanism 2 operates, and the motor 203 installed in the placement groove 202 on the inner wall of the cover 1 starts. The placement groove 202 prevents the motor 203 from becoming unstable during operation. The motor 203 drives the transmission column 204 to rotate, and the transmission column 204 in turn drives the fan 205 to rotate. The airflow generated by the fan 205 drives the hot air outward through the interior of the cooling hole 201. The guide plate 206 set on the inner wall of the cooling hole 201 can effectively guide the airflow direction and prevent the hot air from flowing back and causing poor heat dissipation. A hinge 207 and a protective cover 208 are installed at the outlet of the cooling hole 201. When heat dissipation is not required, the protective cover 208 flips and closes under the action of the hinge 207 to prevent foreign objects from entering the interior of the cooling hole 201 and causing damage to the components.
