Technical Field
[0001] This utility model relates to the field of automotive engine cover technology, specifically to an automotive engine cover that can reduce weight. Background Technology
[0002] The engine compartment of a car contains all the important components of the car. The engine cover plays a role in protecting these components. The engine operates in a high temperature, high pressure and flammable environment for a long time. It is inevitable that an explosion accident will occur due to the wear and tear of parts and overheating. The engine cover can effectively block the air and reduce the combustion of flames, thereby reducing the risk. There are many kinds of car engine covers on the market.
[0003] However, conventional car hoods do not easily reduce the weight of the hood itself. When the hood is heavy, it increases the overall weight of the car. This makes it difficult to properly position the hood when it is closed. As a result, even slight wear on the connection between the hood and the car can cause the hood to loosen on bumpy roads. Furthermore, it is difficult to reduce engine noise, which can lead to noise leakage and disturb the surrounding road environment when there is a lot of engine noise. Therefore, this invention provides a car hood that can reduce weight to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a car engine hood that can reduce weight, thereby solving the problems mentioned in the background art, where conventional car engine hoods are not conducive to reducing their own weight. As a result, when the car engine hood is heavy, it leads to an increase in the overall weight of the car, making it difficult to assist in positioning when the car engine hood is closed. Consequently, when there is slight wear on the part of the car engine hood that connects to the car, the car engine hood is prone to loosening on bumpy roads. This also makes it difficult to reduce the noise generated by the car engine, and when the engine noise is high, it is easy for noise to leak out and interfere with the surrounding road driving environment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a car engine hood that can reduce weight, comprising:
[0006] An engine hood body, with a plate fixedly connected to its upper end;
[0007] Also includes:
[0008] A fixed frame is fixedly connected to the engine hood body, and a slider is slidably connected inside the fixed frame, with a spring fixedly connected to the inner end of the slider.
[0009] An arc-shaped bracket is fixedly connected to the upper inner part of the engine hood body, and a weight-reducing support structure is provided on the outer side of the arc-shaped bracket to reduce the weight of the engine hood. The weight-reducing support structure includes side support rods, reinforcing ribs and honeycomb plates. Side support rods are fixedly connected to both the left and right sides of the arc-shaped bracket, and reinforcing ribs are fixedly connected to the lower end of the side support rods. A honeycomb plate is provided on the lower side of the arc-shaped bracket.
[0010] The inner end of the arc-shaped bracket is provided with a square sound damping plate for reducing engine noise.
[0011] Preferably, the upper left and right sides of the engine hood body are fixedly connected to a fixing frame.
[0012] Preferably, a spring is fixedly connected inside the fixed frame.
[0013] Preferably, the outer end of the reinforcing rib is fixedly connected to the engine hood body, and the reinforcing rib array is arranged at the inner outer end of the engine hood body.
[0014] Preferably, the outer side of the honeycomb panel is fixedly connected to the engine hood body, and the lower inner side of the engine hood body is tightly fitted with an airbag.
[0015] Preferably, the upper end of the square sound damper is fixedly connected to the engine hood body, and the interior of the square sound damper is filled with sound insulation cotton. A trapezoidal sound damper is symmetrically arranged in the middle of the engine hood body, and the interior of the trapezoidal sound damper is filled with sound insulation cotton. The square sound damper is symmetrically arranged on the left and right sides inside the engine hood body, and a silicone strip is fixedly connected to the outer ring of the square sound damper.
[0016] Compared with the prior art, the beneficial effects of this utility model are: the car engine cover that can reduce weight can assist in positioning the car engine cover, avoid the car engine cover from becoming loose after the slot connection part is worn, and can reduce the weight of the car engine cover and reduce the overall weight of the car while increasing the stability support of the internal structure of the car engine cover. It can also reduce the noise generated by the engine and has strong practicality.
[0017] 1. It is equipped with a plate, a fixed frame and a slider. The fixed frame is fixedly connected to the upper end of the engine hood body. The fixed frame is fixedly connected to the inside of the fixed frame and the slider is fixedly connected to the outer end of the spring. When the slider is squeezed, the spring fixedly connected to the inner end of the slider is subjected to pressure and deforms, so that the slider slides into the inside of the fixed frame, which can provide auxiliary limit when the car engine hood is closed.
[0018] 2. The engine hood body is equipped with fixed frames on both the left and right sides of the upper end. The fixed frames are symmetrically arranged. When the engine hood body is impacted, the limiting effect of the insert plate installed on the upper end of the engine hood body is prevented from deteriorating, which can increase the tightness of the connection between the car engine hood and the car.
[0019] 3. It is equipped with an arc-shaped bracket, side support rods and reinforcing ribs. The arc-shaped bracket is fixedly connected to the inside of the engine hood body, and the side support rods are fixedly connected to the left and right sides of the arc-shaped bracket respectively. The side support rods are fixedly connected to the engine hood body on the outside, and the side support rods are fixedly connected to the engine hood body through reinforcing ribs at the outer ends. This can provide stable support for the internal corners of the car engine hood.
[0020] 4. It is equipped with an arc-shaped bracket, side support rods and honeycomb panels. By setting the interior of the arc-shaped bracket and side support rods as hollow support structures and the interior of the honeycomb panels as honeycomb structures, the weight of the car engine hood can be reduced when the arc-shaped bracket, side support rods and honeycomb panels provide support.
[0021] 5. It is equipped with square sound damping plates, trapezoidal sound damping plates and sound insulation cotton. By distributing square sound damping plates and trapezoidal sound damping plates inside the engine hood body, and filling the square sound damping plates and trapezoidal sound damping plates with sound insulation cotton, the noise generated by the engine can be reduced when the engine is started.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 1-5 This utility model provides a technical solution: a car engine cover that can reduce weight, including an engine cover body 1, a insert plate 2, a fixing frame 3, a slider 4, a spring 5, an arc-shaped bracket 6, a side support rod 7, a reinforcing rib 8, an airbag 9, a honeycomb plate 10, a square sound-damping plate 11, a trapezoidal sound-damping plate 12, sound insulation cotton 13, and a silicone strip 14.
[0030] Existing car hoods do not make it easy to reduce the weight of the hood itself. When the hood is heavy, it increases the overall weight of the car. They also make it difficult to provide auxiliary positioning when the hood is closed. As a result, when there is slight wear on the part where the hood connects to the car, the hood may become loose on bumpy roads. Furthermore, they do not make it easy to reduce the noise generated by the car engine. When the engine noise is high, it may leak out and disturb the surrounding road environment.
[0031] An insert plate 2 is fixedly connected to the upper end of the engine hood body 1, and a fixing frame 3 is fixedly connected to the upper end of the engine hood body 1. A spring 5 is fixedly connected inside the fixing frame 3, and a slider 4 is fixedly connected to the outer end of the spring 5. The outer side of the slider 4 is slidably connected inside the fixing frame 3.
[0032] When auxiliary positioning of the engine hood body 1 is required, after the engine hood body 1 is pushed to connect with the front of the car, the insert plate 2 is connected to the inside of the car. At this time, the outer side of the slider 4 is squeezed by the arc block inside the car, which causes the spring 5 fixedly connected to the inner end of the slider 4 to be under pressure and deform, squeezing the slider 4 inward, so that the slider 4 slides into the inside of the fixing frame 3. When the engine hood body 1 is fully connected to the front of the car, the spring 5 fixedly connected to the inner end of the slider 4 loses pressure and restores its elasticity, so that the slider 4 slides outward inside the fixing frame 3 until the outer side of the slider 4 is connected to the inside of the front of the car. This can provide auxiliary positioning of the car engine hood and prevent the car engine hood from becoming loose after the connection part of the slot is worn.
[0033] Arc-shaped brackets 6 are fixedly connected to the upper left and right sides of the interior of the engine hood body 1, and side support rods 7 are fixedly connected to the outer left and right sides of the arc-shaped brackets 6. The lower end of the side support rods 7 is fixedly connected to the reinforcing ribs 8, and the outer end of the reinforcing ribs 8 is fixedly connected to the engine hood body 1. The reinforcing ribs 8 are arranged in an array inside the engine hood body 1. The lower left and right sides of the engine hood body 1 are fixedly connected to the honeycomb panels 10. The lower side of the honeycomb panels 10 is tightly fitted with the airbag 9, and the outer side of the airbag 9 is tightly fitted with the engine hood body 1.
[0034] When it is necessary to reduce the weight of the car hood, an arc-shaped bracket 6 is fixedly connected to the inner edge of the hood body 1. The arc-shaped bracket 6 is hollow inside. Side support rods 7 are fixedly connected to the left and right sides of the arc-shaped bracket 6, and reinforcing ribs 8 are fixedly connected to the lower end of the side support rods 7. The reinforcing ribs 8 are arrayed on the left and right sides inside the hood body 1. The side support rods 7 are also hollow. A honeycomb plate 10 is fixedly connected to the lower inside of the hood body 1. The honeycomb plate 10 has a honeycomb structure inside, and the airbag 9 is tightly attached to the lower inside of the honeycomb plate 10 to support the sharp corners of the lower inside of the hood body 1. This can reduce the weight of the car hood and the overall weight of the car by increasing the stability support of the internal structure of the car hood.
[0035] Square sound damping plates 11 are fixedly connected to the left and right sides of the interior of the engine hood body 1, and the interior of the square sound damping plates 11 is filled with sound insulation cotton 13. A trapezoidal sound damping plate 12 is fixedly connected to the middle of the engine hood body 1, the interior of the trapezoidal sound damping plate 12 is filled with sound insulation cotton 13, and a silicone strip 14 is fixedly connected to the outer ring of the trapezoidal sound damping plate 12. The rear end of the silicone strip 14 is fixedly connected to the square sound damping plate 11.
[0036] When it is necessary to reduce engine noise, square sound damping plates 11 are fixedly connected to the left and right sides inside the engine hood body 1, and trapezoidal sound damping plates 12 are fixedly connected to the center inside the engine hood body 1. The square sound damping plates 11 and trapezoidal sound damping plates 12 are filled with sound insulation cotton 13 respectively. The square sound damping plates 11 and trapezoidal sound damping plates 12 are distributed in a dispersed manner. Silicone strips 14 are fixedly connected to the outer ring of the square sound damping plates 11 and trapezoidal sound damping plates 12. When the engine hood body 1 is fully connected to the car, the silicone strips 14 isolate the noise emitted by the engine, reduce external wind noise, and can reduce the noise generated by the engine, which is highly practical.
