Description

Technical Field

[0002] The car engine hood is an important part of the car, usually located on the top of the engine area, used to cover and protect the engine and its related components. In terms of design, the car engine hood usually has vents and heat dissipation holes to ensure that the engine gets adequate ventilation and cooling, but the ventilation holes on some car engine hoods are continuously open. When the engine is not in use, dust or debris from the outside may enter, causing the vents to become blocked, thereby affecting the ventilation effect.

[0003] After searching, Chinese patent announcement number: CN219728350U discloses a car engine hood, including a cover plate, the inner cavity of the cover plate is fixedly connected to a load-bearing plate, a push plate is arranged between the load-bearing plate and the cover plate, the top of the push plate is tightly fitted with the connection of the cover plate, the bottom of the push plate is evenly fixedly connected with a compression spring, and the bottom of the compression spring is fixedly connected with the connection of the load-bearing plate. The utility model can be constructed into a car engine hood by arranging a cover plate, a load-bearing plate, a push plate, a compression spring, a buffer layer and a sound insulation pad. At the same time, the arrangement of the compression spring and the buffer layer can provide buffer support to the cover plate when it is slightly hit, so that it can be restored to its original state and avoid deformation. By arranging the above structure, the car engine hood has the advantage of having a buffer support function when in use, which solves the problem that the original car engine hood does not have a buffer support function when in use, thereby meeting the needs of customers.

When not in use, some bird droppings, dust and other debris will enter it, causing the ventilation holes to be blocked, reducing the heat dissipation effect. Therefore, a car engine cover is proposed to solve the above problem. Utility Model Content

Since it is a prior art, it will not be described in detail in this case. A round rod 24 is fixedly connected to the upper surface of the cooling fan 25, and a rectangular groove 210 is provided on the inner wall of the bottom end of the fixed shell 22.

[0034] Reference Figure 2 - Figure 3 , Figure 5 The filter assembly 3 includes a filter plate 31. The filter plate 31 is a prior art, which can filter dust from the outside to prevent dust from entering the interior of the car and affecting the service life of the engine, thereby improving the protection. The filter plate 31 penetrates and slides on the right surface of the bottom end of the fixed shell 22. A through groove 33 is provided on the right surface of the filter plate 31, and a push handle 34 is slidably connected to the inner wall of the through groove 33.

[0035] Reference Figure 1 , Figure 3 - Figure 4 , Figure 6The heat dissipation component 2 also includes a protective cover 21, which is slidably connected to the inner wall of the ventilation hole 4. A sleeve 23 is fixedly connected to the lower surface of the protective cover 21. A spiral groove 27 is provided on the inner wall of the sleeve 23. The spiral groove 27 has a certain curvature. When the slide bar 26 slides on the inner wall, it will drive the sleeve 23 to move upward or downward along its amplitude, so that the lifting and lowering of the protective cover 21 can be controlled. An annular groove 28 is provided at the bottom end of the inner wall of the sleeve 23. An inclined block 29 is fixedly connected to the upper side of the inner wall of the sleeve 23 adjacent to the annular groove 28. A slide bar 26 is fixedly connected to the front surface of the top of the round rod 24. The slide bar 26 slides on the inner wall of the spiral groove 27. The slide bar 26 slides on the inner wall of the annular groove 28. The spiral groove 27 is connected to the annular groove 28. When the slide bar 26 disengages from the inner wall of the spiral groove 27, it will enter the inner wall of the annular groove 28. At this time, the rotating round rod 24 will drive the slide bar 26 to slide on the inner wall of the annular groove 28 all the time, so that the protective cover 21 will not be closed.

[0036] Reference Figure 3 , Figure 5 The inner wall of the right end of the filter plate 31 is elastically connected with the block 32 through the spring 35. The spring 35 always pushes the block 32 forward by its own elasticity to ensure the stability of its limit. The left surface of the push handle 34 is fixedly connected to the rear end of the right surface of the block 32. The block 32 is slidably connected to the inner wall of the right end of the filter plate 31.

Arranging multiple groups can ensure the stability of the filter plate 31 during installation.

[0037] Working principle: When the engine covered by the cover body 1 needs to be cooled during use, the cooling fan 25 is started, and the cooling fan 25 drives the round rod 24 to rotate, and the round rod 24 drives the slide bar 26 to rotate. At the same time, the slide bar 26 slides on the inner wall of the spiral groove 27, and the slide bar 26 drives the sleeve 23 to move upward along the spiral direction of the spiral groove 27. The sleeve 23 drives the protective cover 21 to slide upward on the inner wall of the ventilation hole 4 until the slide bar 26 slides out from the inner wall of the spiral groove 27 and enters the inner wall of the annular groove 28. At this time, the slide bar 26 starts to Finally, the inner wall of the annular groove 28 rotates, and the protective cover 21 will always remain in an open state, so the engine can be cooled, and the cooling fan 25 can speed up the cooling speed. When cooling is not needed, the cooling fan 25 is stopped, and then the cooling fan 25 is started again to reverse, and the cooling fan 25 will drive the round rod 24 to reverse. At this time, the sliding rod 26 will contact the inclined block 29 and slide into the inner wall of the spiral groove 27 along its inclined surface, so that the sleeve 23 can be driven to fall, and the protective cover 21 will also fall and close accordingly. After closing, the cooling fan 25 can be turned off.

[0038] When heat dissipation is in progress, the filter plate 31 can filter out dust from the outside. When the filter plate 31 needs to be replaced, it only needs to push the push handle 34, and the push handle 34 will drive the block 32 to move until the block 32 pushes the inner wall of the rectangular groove 210 to remove the filter plate 31. When installing, it only needs to insert the filter plate 31 into the inner wall of the bottom end of the fixed shell 22. During the insertion process, the fixed shell 22 will push it to move along the inclined surface of the block 32, and the block 32 will squeeze the spring 35 until the block 32 overlaps with the rectangular groove 210. At this time, the cooling fan 25 will use its own elasticity to push the block 32 to move in the opposite direction and insert it into the inner wall of the rectangular groove 210. In this way, the installation can be completed quickly and conveniently, thereby improving the installation efficiency.

[0039] 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.
