Description

Technical Field

[0001] This utility model relates to the field of engine cover technology, and in particular to a pressure-bearing automobile engine cover. Background Technology

[0002] With the development of the automotive industry, the hood plays a vital role in improving overall vehicle performance, increasing safety, and reducing vehicle weight. Especially when facing complex conditions such as high temperatures, high pressures, and collisions, the performance of the hood directly impacts the reliability and safety of the vehicle. To enhance the hood's impact resistance, improve its stability, and increase its durability over long periods, designers have gradually introduced pressure-bearing designs, combining high-strength materials and optimized structures to meet the higher requirements of modern automobiles for their hoods.

[0003] Existing automotive engine hoods are generally made of metal materials (such as aluminum alloys or steel plates), with sound-absorbing cotton or sound-insulating materials inside to reduce engine noise. Traditional designs mainly rely on structural reinforcement (such as adding metal ribs) to increase the hood's strength, thereby enhancing its load-bearing capacity and resistance to deformation. Reinforcing plates and honeycomb structures are widely used to improve the hood's strength and reduce weight. However, traditional technologies are prone to problems such as sound-absorbing material shedding or hood structure deformation when subjected to high temperatures, prolonged use, and external impacts.

[0004] Traditional methods of fixing sound-absorbing cotton in engine hoods typically rely on adhesive, which can easily cause the cotton to fall off under high temperatures and long-term operation, thus affecting the sound insulation effect and causing instability of the hood. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pressure-bearing automobile engine cover, which aims to improve the problem that the sound-absorbing cotton of the cover is easily detached at high temperatures when it is glued with adhesive.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure-bearing automobile engine cover, comprising a cover body, wherein sound-absorbing cotton is provided inside the cover body, a connecting component is provided between the sound-absorbing cotton and the cover body, and a limiting component is provided inside the cover body;

[0007] The connecting component includes a sliding plate, which is slidably connected inside the cover body. A limiting groove is formed inside the sliding plate. A limiting block is fixedly connected inside the cover body. The sliding plate is slidably connected to the outer wall of the limiting block through the limiting groove. A locking block is fixedly connected to one side of the sliding plate. A fixing groove is formed inside the sound-absorbing cotton. The locking block is engaged with the fixing groove. A reset component is provided inside the cover body.

[0008] As a further description of the above technical solution:

[0009] The reset assembly includes a telescopic rod, the outer wall of which is fitted with a spring. One end of the telescopic rod and the spring are both fixedly connected to the other side of the slide plate, and the other end of the telescopic rod and the spring are both fixedly connected to the inside of the cover body.

[0011] The limiting component includes a limiting plate, one side of which is fixedly connected to the inside of the cover body, and the outer wall of the sound-absorbing cotton is fitted between the limiting plate and the cover body.

[0012] As a further description of the above technical solution:

[0013] A reinforcing plate is fixedly connected inside the cover body, and the reinforcing plate has honeycomb grooves inside.

[0014] As a further description of the above technical solution:

[0015] A reinforcing ring is fixedly connected inside the reinforcing plate, and a lubricating oil detection port is provided inside the reinforcing ring.

[0016] As a further description of the above technical solution:

[0017] Both the cover body and the sound-absorbing cotton have a lubricating oil detection port.

[0018] As a further description of the above technical solution:

[0019] The reinforcing plate is 3cm thick and is used to increase the weight and strength of the engine cover.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the sound-absorbing cotton and the cover body are firstly fitted into the fixing groove by a locking block.

[0030] 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.

[0031] Reference Figures 1-5 This utility model provides an embodiment of a pressure-bearing automobile engine cover, comprising a cover body 1, with sound-absorbing cotton 3 disposed inside the cover body 1. The sound-absorbing cotton 3 can effectively reduce the noise generated during engine operation, improve the quietness of the entire vehicle, and also play a certain role in heat insulation, preventing high temperature from affecting the cover body 1. A connecting component is provided between the sound-absorbing cotton 3 and the cover body 1, which can stably fix the sound-absorbing cotton 3 inside the cover body 1, preventing the sound-absorbing cotton 3 from falling off due to vibration or high temperature, and improving the service life and reliability of the cover body 1.

[0032] The connecting assembly includes a sliding plate 7, which is slidably connected inside the cover body 1, allowing the sliding plate 7 to move along the interior of the cover body 1. This facilitates the installation and removal of the sound-absorbing cotton 3 and improves maintenance convenience. A limiting groove 9 is provided inside the sliding plate 7 to limit its movement, ensuring it slides along a fixed trajectory and preventing deviation. A limiting block 6 is fixedly connected inside the cover body 1. The limiting block 6 cooperates with the limiting groove 9 to constrain the sliding plate 7 during movement, thereby ensuring its stability and preventing misalignment. The sliding plate 7 is slidably connected to the outer wall of the limiting block 6 via the limiting groove 9, ensuring that the sliding plate 7 slides in a predetermined direction, improving the accuracy and stability of the connecting components. A locking block 8 is fixedly connected to one side of the sliding plate 7, which can fit into the fixing groove 4 opened inside the sound-absorbing cotton 3. Support frames are fixed on both sides of the sound-absorbing cotton 3, and the fixing groove 4 is opened inside the support frame, improving the strength of the fixing groove 4. The sound-absorbing cotton 3 is firmly fixed by the structural fit, avoiding the problem of the sound-absorbing cotton 3 falling off due to high temperature or vibration caused by traditional bonding methods, thereby improving the stability of the sound-absorbing cotton 3. A reset component is set inside the cover body 1. The reset component can make the sliding plate 7 return to its original position after being subjected to force, ensuring that the connecting components can work stably for a long time. The reset component includes a telescopic rod 10, which can provide support force when the sliding plate 7 slides, so that the sliding plate 7 can return to its initial state after the external force is removed, ensuring the fixing effect of the sound-absorbing cotton 3. A spring 11 is fitted onto the outer wall of the telescopic rod 10. The spring 11 generates elastic force under the action of the telescopic rod 10, further improving the reset capability and preventing the slide plate 7 from shifting due to external vibrations. One end of both the telescopic rod 10 and the spring 11 is fixedly connected to the other side of the slide plate 7, ensuring a reliable connection between the reset assembly and the slide plate 7, providing a stable reset function. The other ends of both the telescopic rod 10 and the spring 11 are fixedly connected inside the cover body 1, ensuring the overall stability and reliability of the reset assembly and improving the durability of the cover body 1. The limiting assembly includes a limiting plate 5, one side of which is fixedly connected inside the cover body 1. The limiting plate 5 further limits the sound-absorbing cotton 3, ensuring it is stably fitted inside the cover body 1 and preventing loosening during long-term use. The outer wall of the sound-absorbing cotton 3 is fitted between the limiting plate 5 and the cover body 1. Through the combined action of the limiting plate 5 and the cover body 1, the sound-absorbing cotton 3 remains fixed, improving the overall structural stability of the engine cover and extending the service life of the sound-absorbing cotton 3.

[0033] Reference Figure 2 and Figure 3A reinforcing plate 2 is fixedly connected inside the cover body 1. The reinforcing plate 2 is used to improve the overall strength of the cover body 1, enhance the stability of the cover body 1 under external pressure, prevent the cover body 1 from deforming due to long-term use or external impact, and improve the durability of the engine cover. The reinforcing plate 2 has honeycomb grooves 12 inside. The honeycomb grooves 12 adopt a uniformly distributed structural design, which can effectively reduce its own weight while maintaining the strength of the reinforcing plate 2, reduce the overall burden on the engine cover, improve the fuel economy of the vehicle, and at the same time improve the impact resistance of the structure, so that the cover body 1 can effectively disperse stress when subjected to external impact, reducing the risk of damage. A reinforcing ring 14 is fixedly connected inside the reinforcing plate 2. The setting of the reinforcing ring 14 further enhances the overall rigidity of the reinforcing plate 2, so that it can maintain stable mechanical properties during long-term use and improve the deformation resistance of the engine cover. The reinforcing ring 14 has a lubricating oil detection port 2 15 inside, which is used to detect the condition of the lubricating oil inside the engine. This allows maintenance personnel to quickly check the quality and level of the lubricating oil, improving engine maintenance efficiency and reducing the risk of engine failure due to poor lubrication. Both the cover body 1 and the sound-absorbing cotton 3 have lubricating oil detection ports 1-13 inside. The inclusion of these ports makes detection more convenient, allowing monitoring of the engine lubricating oil condition without disassembling the cover body 1, improving maintenance convenience, ensuring the normal operation of the engine's internal lubrication system, and extending the engine's service life. The reinforcing plate 2 is 3cm thick. This thickness effectively enhances the load-bearing capacity of the reinforcing plate 2, giving it better resistance to internal engine vibration and external pressure, thus improving the stability and service life of the engine cover.

[0034] Working principle: When using this pressure-bearing car engine cover, when the sound-absorbing cotton 3 is installed inside the cover body 1, the sound-absorbing cotton 3 and the cover body 1 are fitted into the fixing groove 4 by the locking block 8. The locking block 8 is limited in the cover body 1 by the sliding plate 7, and slides on the outer wall of the limiting block 6 by the limiting groove 9 in the sliding plate 7 to prevent the locking block 8 from being misaligned. Then, the locking block 8 is supported by the tension of the spring 11 so that the locking block 8 can be stably fitted into the fixing groove 4. The sound-absorbing cotton 3 is further limited on both sides of the cover body 1 by the limiting plate 5 to prevent it from falling, thus achieving the effect of facilitating the fixing of the sound-absorbing cotton 3.

[0035] The reinforcing plate 2 inside the cover body 1 improves the pressure resistance and strength of the cover body 1. The honeycomb grooves 12 arranged evenly inside the reinforcing plate 2 can improve the strength of the cover body 1 while reducing its weight. In addition, it can absorb impact energy when subjected to impact. At the same time, the reinforcing ring 14 inside the reinforcing plate 2 can improve the strength around the lubricating oil detection port 15, making it easier to check the lubricating oil in the engine, thus achieving the effect of improving the strength of the engine cover.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
