Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile front cover accessory. Background Art

[0002] The internal structure of a car's engine compartment is complex, containing multiple key components such as the engine, battery, cooling system, and electronic control equipment. To protect these components from external environmental factors, car manufacturers usually install protective plastic parts on the front cover. Such plastic parts can not only reduce the entry of dust, moisture, and debris into the engine compartment, but also provide certain heat insulation and shock absorption functions, ensuring the safety of components inside the engine compartment and increasing their service life.

[0003] However, general automobile hood accessories are relatively simple in structure and material composition, making the accessories inconvenient to install. Screws are required for fixing, which is troublesome to operate. In addition, the shock-absorbing effect brought by the material itself is limited. Under strong vibration, there is still a high risk of damage. In addition, the material composition of ordinary automobile hood accessories is relatively simple and the protective effect is poor. Therefore, a car hood accessory is needed to solve the existing shortcomings. Utility Model Content

[0026] The outer shell is connected to the internal equipment of the engine compartment through the fixing part 10, and is connected to the inner side of the front cover through the fixing part 2 11. The outer shell is provided with support to reduce shock absorption through the buffer mechanism and rubber column. The outer shell is provided with a plurality of heat dissipation holes for dissipating the heat generated by the engine compartment and reducing the direct transfer of heat and accumulation inside the outer shell. The porous structure helps to enhance the overall protective performance of the outer shell and improve the supporting effect of the outer shell on the front cover.

[0027] like Figure 5 As shown, the shell 1 is composed of an inner layer 12, an outer layer 14 and a nano thermal insulation layer 13. The inner layer 12 is made of high-density polyamide material, the outer layer 14 is made of polytetrafluoroethylene material, and a silica aerogel thermal insulation layer is provided between the inner layer 12 and the outer layer 14.

[0028] A nano-insulation layer 13, such as silica aerogel, is added between the two layers to further enhance the insulation and reduce the conduction of engine heat into the cockpit. The flame retardancy of the outer layer 14 complies with the GB8410-2006 and QJLYJ7110335B-2019 standards, with a burning rate not exceeding 80 mm / min. The overall wall thickness of the plastic part is 2.5 mm, which has excellent impact resistance and thermal insulation properties, making it suitable for long-term use in high-temperature and complex environments.

[0029] like Figure 5 As shown, the outer surface of the shell 1 is coated with a hydrophobic nano-coating to achieve a self-cleaning function; the material contains an environmentally friendly antibacterial agent to reduce bacterial growth and improve the air quality in the vehicle.

[0030] like Figure 1 and Figure 3As shown, the buffer mechanism 3 includes a buffer shell 301, a fixed block 302, a guide column 303 and a return spring 304. The fixed block 302 and the guide column 303 are symmetrically arranged. The fixed block 302 is fixedly connected to the outside of the buffer shell 301. The guide column 303 is fixedly connected to the front side of the shell 1. One end of the guide column 303 is movably connected to the inside of the fixed block 302. The return spring 304 is fixedly connected to the inside of the buffer shell 301. A group of symmetrical receiving grooves 7 are opened on the front side of the shell 1. The receiving grooves 7 are all through-arranged. The end of the return spring 304 away from the buffer shell 301 is fixedly connected to the inside of the receiving groove 7. The fixing parts 10 are symmetrically arranged and the fixing parts 10 are fixedly connected to the inside of the engine compartment.

[0031] The opening at the center of the buffer shell 301 is respectively engaged with the fixing part 10, thereby connecting the front side of the shell 1 with the internal setting of the engine compartment. At this time, the buffer shell 301 is in conflict with the interior of the engine compartment under the action of the return spring 304. If the front cover vibrates, the return spring 304 can absorb the vibration of the front cover, reduce the deformation of the front cover, and reduce the contact between the inner parts of the front cover and the internal equipment of the engine compartment. The fixing block 302 moves along the guide column 303 to assist the buffer shell 301 in changing its position.

[0032] like Figure 1 、 Figure 2 and Figure 4 As shown, the clamping mechanism 4 includes a rotating column 401, a gear 402, a rack 403 and a clamping strip 404. The rack 403 and the clamping strip 404 are symmetrically arranged with respect to the axis of the rotating column 401 as the origin. The clamping strip 404 is fixedly connected to one end of the rack 403 respectively. The rotating column 401 passes through the gear 402, and the rotating column 401 is fixedly connected to the gear 402. The rack 403 is meshed with the gear 402. The gear 402 is movably connected to the inside of the shell 1 through the rotating column 401. The rack 403 is movably connected to the inside of the shell 1, and the clamping strip 404 is movably connected to the back side of the shell 1. The second fixing member 11 is fixedly connected to the inner side of the front cover. The second fixing member 11 is T-shaped. The second fixing member 11 is located on the opposite side of the clamping strip 404. The front side of the shell 1 is threadedly connected to the adjusting column 8. The end of the adjusting column 8 is fixedly connected to the cross block 9. The other end of the cross block 9 is movably connected to the inside of the rotating column 401.

[0033] By matching the positioning hole 5 on the back side of the shell 1 with the positioning column 6, the back side of the shell 1 is connected to the inner side of the front cover. At this time, the second fixing piece 11 is located on the opposite side of the clamping strip 404. By rotating the adjusting column 8, the cross block 9 is rotated, and the cross block 9 is completely inserted into the interior of the rotating column 401, thereby driving the rotating column 401 and the gear 402 to rotate. Since the gear 402 is engaged with the rack 403, the two clamping strips 404 are controlled to approach each other until the clamping strip 404 clamps the second fixing piece 11. At this time, the shell 1 can be fixed to the inner side of the front cover, which is beneficial to improving the installation efficiency and stability of the shell 1.
