Description

Technical Field

[0001] This utility model relates to the field of automotive hood technology, and specifically discloses a carbon fiber composite automotive hood with a perforated design. Background Technology

[0002] The car hood, also known as the engine cover, is an important component covering the engine compartment at the front of a car. Its primary function is to protect the engine from external environmental influences. Whether in rain, snow, or on dusty roads, the hood effectively prevents moisture and impurities from entering the engine compartment, thus ensuring the engine's normal operation.

[0003] The hood of a car is not only an important component of the vehicle, but also plays a vital role in protecting the engine, improving vehicle performance, and enhancing the appearance. For example, the utility model with authorization announcement number CN219790314U discloses a front hood for a car, including a hood and an air duct assembly. The hood has integrally formed side skirts on both sides, and multiple independent exhaust holes are opened at the front end of the side skirts. At the same time, the air duct assembly is movably connected to the inner wall of the front end of the exhaust holes. Furthermore, a first-stage heat dissipation window and a second-stage heat dissipation window are opened sequentially from front to back at the center of the hood. Multiple horizontally arranged ribs are fixedly connected inside the hood, and buffer rods are fixedly connected to both sides of the ribs. This utility model provides a front hood for a car to solve the problems of existing technologies in vehicle heat dissipation, which cannot quickly dissipate the high temperature generated by the engine, thus easily causing thermal decay and reducing vehicle power due to engine high temperature, and the inability to introduce outside air into the engine compartment to increase the engine cooling effect when the vehicle is in motion. Currently, some special vehicles, such as off-road vehicles and patrol cars, need to increase the intensity of lighting in certain areas when driving at night, especially in special road sections or situations. However, most vehicles have limited lighting intensity. If the headlights are modified to increase the lighting intensity in ordinary road conditions, it is easy to cause light pollution and illegal modifications when driving in urban areas. Therefore, additional lighting tools are usually added to the vehicle. In order to further ensure the best lighting effect without affecting the overall lighting and the driver's vision, holes are cut in the front hood to facilitate the installation of additional lighting fixtures. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a carbon fiber composite car drilling machine cover to solve the problem of adding additional lighting fixtures to the machine cover in order to further improve the brightness of special vehicles when encountering special road sections and events.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a carbon fiber composite car hood with perforation, comprising a hood assembly, wherein the hood assembly includes a hole assembly, the hole assembly being symmetrically distributed along both sides of the front end of the hood assembly;

[0006] The hood assembly includes a hood body and a hood rotation shaft seat;

[0007] The hole assembly includes a via.

[0008] Furthermore, the end of the cover body has symmetrically distributed cover rotation shaft seats on the inward side, and the surface of the cover rotation shaft seats has shaft holes. Cover closing buffer posts are distributed at both ends of the inward side of the cover body. Cover opening support seat is provided on the front end side of the cover body. Lock head is provided at the middle of the front end of the cover body. Guide groove is provided on the outward side of the cover body. Guide groove is symmetrically distributed along both sides of the cover body.

[0009] Furthermore, the hood body has a core layer, a reinforcing layer and a base layer in sequence. The surface of the core layer is fixedly covered with the reinforcing layer, and the outside of the reinforcing layer is wrapped with the base layer. The core layer is made of resin material, the reinforcing layer is made of glass fiber material, and the base layer is made of multiple layers of carbon fiber composite.

[0010] Furthermore, the through holes are symmetrically distributed on both sides of the front end of the cover body. An inner sleeve is inserted into the through hole. The lower end of the inner sleeve is provided with an annular protrusion. Several mounting holes penetrating the interior are opened on the surface of the annular protrusion. Several mounting rings are distributed on the inner side of the inner sleeve.

[0011] Furthermore, the end face of the inner sleeve is covered with a sealing component, which includes a sealing plate. The surface of the sealing plate is fitted to the end face of the inner sleeve. A plug is provided on the side of the sealing plate near the inner sleeve. The plugs are symmetrically distributed along the end face of the inner sleeve. A pin groove is opened inside the plug. A locking pin is slidably sleeved inside the pin groove. The end of the locking pin has a curved structure. A spring is also provided inside the pin groove. The two ends of the spring are fixedly installed to the surface of the locking pin and the inner wall of the pin groove, respectively.

[0012] Furthermore, the end face of the built-in sleeve is provided with a slot, the surface of the insert rod is slidably inserted into and connected with the inner wall of the slot, the inner wall of the slot is provided with an arc-shaped groove, and the end curved surface of the locking pin is tightly fitted against the surface of the arc-shaped groove.

[0013] Furthermore, the outer end of the sealing plate is provided with a frame, a counterweight plate is inserted inside the frame, and a cover is attached to the surface of the sealing plate. The outer end face of the cover is on the same horizontal plane as the outer side of the cover body. The inner side of the cover is sleeved with the frame.

[0029] The following detailed description illustrates the specific implementation method:

[0030] Example

[0031] like Figures 1 to 10 As shown, a carbon fiber composite car hood with holes is disclosed, including a hood assembly 1, the hood assembly 1 including hole assembly 2, the hole assembly 2 being symmetrically distributed along both sides of the front end of the hood assembly 1;

[0032] The hood assembly 1 includes a hood body 10 and a hood rotating shaft seat 11;

[0033] Hole assembly 2 includes via 20.

[0034] A hood rotating shaft seat 11 is symmetrically distributed on the inward side of the end of the hood body 10. The hood rotating shaft seat 11 and the hood body 10 are integral structures. A shaft hole 12 is opened on the surface of the hood rotating shaft seat 11. The hood rotating shaft seat 11 and the shaft hole 12 can be based on the vehicle body. When the hood body 10 is opened or closed, the rotating shaft at the engine position of the vehicle body passes through the shaft hole 12, which allows the hood body 10 to rotate normally. A hood closing buffer post 13 is distributed at both ends on the inward side of the hood body 10. The hood closing buffer post 13 is a rubber post structure. The hood closing buffer post 13 is fixed to the inner wall of the hood body 10 by screws. The hood closing buffer post 13 can provide buffer support when the hood body 10 is closed, avoiding hard impact damage between the hood body 10 and the vehicle body. A hood is provided on the front side of the hood body 10. Open the support base 14. The hood opening support base 14 is fixed to the inside of the hood body 10 by screws. After the hood body 10 is flipped open, the hood opening support base 14 can be inserted and docked with the support strip on the vehicle body for limiting. This ensures that the hood body 10 can be positioned after being unfolded when the engine area is being inspected. A lock head 16 is provided at the front center of the hood body 10. The lock head 16 has a U-shaped structure. Both ends of the lock head 16 are fixed to the inner wall of the hood body 10 by screws. When the hood body 10 is closed, the lock head 16 can be inserted into the lock groove on the vehicle body and installed as a hood lock. This ensures that the hood body 10 is closed stably when the vehicle is in motion. A guide groove 15 is provided on the outward side of the hood body 10. The guide groove 15 is symmetrically distributed on both sides of the hood body 10. The guide groove 15 can facilitate the guidance of airflow when the vehicle is in motion.

[0035] The hood body 10 consists of a core layer 1001, a reinforcing layer 1002, and a base layer 1003. The reinforcing layer 1002 is fixedly covered on the surface of the core layer 1001, and the base layer 1003 is wrapped around the outside of the reinforcing layer 1002. The core layer 1001 is made of resin material, the reinforcing layer 1002 is made of glass fiber material, and the base layer 1003 is composed of multiple layers of carbon fiber composite. The resin of the core layer 1001 is selected from epoxy resin or vinyl ester. The resin matrix can bond the carbon fibers together, providing good toughness and chemical corrosion resistance, while enhancing the overall performance of the composite material. Glass fiber has good toughness and cost-effectiveness. Combining it with carbon fiber can improve the impact resistance and durability of the composite material, while reducing costs. The multi-layer carbon fiber composite structure has extremely high strength and stiffness, which can significantly improve the mechanical properties and impact resistance of the hood, while maintaining a low weight.

[0036] The through holes 20 are symmetrically distributed on both sides of the front end of the cover body 10, penetrating the interior of the cover body 10. An inner sleeve 21 is inserted into the through hole 20. The lower end of the inner sleeve 21 has an annular protrusion, and several mounting holes 23 are formed on the surface of the annular protrusion, penetrating its interior. The mounting holes 23 are fixed to the inner wall of the cover body 10 by bolts. Several mounting rings 22 are distributed on the inner side of the inner sleeve 21. Any one of the mounting rings 22 is welded and fixed to the inner wall of the inner sleeve 21. The mounting rings 22 are equidistantly distributed in an annular pattern along the inner wall of the inner sleeve 21. The through holes 20 can be additional holes for adding equidistant positioning. The inner sleeve 21 is added within the through hole 20. The structure can prevent excessive force during the installation of the through hole 20 when additional equidistant spacing is used, thus avoiding cracking and deformation of the hole edge. It mainly serves as an auxiliary load-bearing component and a support. The mounting rings 22 distributed on the inner wall of the inner sleeve 21 can be fitted into the lamp holder part of the lamp when it is fitted into the inner sleeve 21, so that the preset installation position of the lower end of the lamp holder corresponds to the mounting ring 22 and can be fixed by screws. Thus, the position positioning of the lamp and the through hole 20 can be realized. The inner sleeve 21 can be installed into the through hole 20 from the inside of the cover body 10 through the annular protrusion and has an anti-detachment effect. The inner sleeve 21 can be fixed to the cover body 10 by screws passing through the mounting hole 23.

[0037] The port of the inner sleeve 21 is spaced from the port of the through hole 20 on the outward side. The end face of the inner sleeve 21 is covered by a sealing component 24. The sealing component 24 can seal the through hole 20 and the inner sleeve 21 when not in use, preventing external dust and rainwater from entering the interior of the cover body 10. When installing the lamp, the connection between the lamp holder and the inner sleeve 21 and the through hole 20 must be sealed to ensure the sealing effect after the lamp is installed. The sealing component 24 includes a sealing plate 241. The surface of the sealing plate 241 is fitted to the end face of the inner sleeve 21. A plug 242 is provided on the side of the sealing plate 241 near the inner sleeve 21. The connection between the insertion rod 242 and the sealing plate 241 is fixed by welding. The insertion rod 242 is symmetrically distributed along the end face of the inner sleeve 21. The insertion rod 242 has a pin groove 248 inside. A locking pin 243 is slidably sleeved inside the pin groove 248. The end of the locking pin 243 has a curved structure. A spring 244 is also provided inside the pin groove 248. The two ends of the spring 244 are fixedly installed to the surface of the locking pin 243 and the inner wall of the pin groove 248, respectively. When the locking pin 243 is squeezed, the compressible spring 244 enters the interior of the pin groove 248. When the locking pin 243 loses its squeezing effect, the spring 244 returns to its original position.

[0038] The end face of the inner sleeve 21 has a slot 245, the position of which corresponds to the position of the insert rod 242. The surface of the insert rod 242 slides into and engages with the inner wall of the slot 245. An arc-shaped groove 247 is provided on the inner wall of the slot 245. The curved surface of the end of the locking pin 243 is tightly fitted against the surface of the arc-shaped groove 247. When the sealing plate 241 needs to be installed, the insert rod 242 slides into and engages with the slot 245. At this time, when the curved surface of the end of the locking pin 243 contacts the port of the slot 245, it is gradually squeezed and compresses the spring 244 into the interior of the pin groove 248. When the sealing plate 241 is fitted with the end face of the inner sleeve 21, the position of the locking pin 243 and the position of the arc-shaped groove 247 are... Correspondingly, through the reset effect of the spring 244, the locking pin 243 springs into the interior of the arc groove 247, thereby achieving a tight fit between the sealing plate 241 and the inner sleeve 21, thus completing the fixation of the sealing plate 241 and the inner sleeve 21. When it is necessary to use the through hole 20 and the inner sleeve 21 for equidistant installation, the machine cover body 10 can be opened to enter the through hole 20 from the inside, and the sealing plate 241 can be pushed by hand or rod to generate a pulling effect relative to the insertion rod 242. Through the arc-shaped compression of the end area of ​​the locking pin 243 against the inner wall of the arc groove 247 and the compression of the spring 244, the insertion rod 242 and the slot 245 can be separated, thereby achieving the disassembly of the sealing plate 241.

[0039] A frame 2401 is provided at the outward end of the sealing plate 241. The frame 2401 has a closed annular structure. One end of the frame 2401 is welded and fixed to the surface of the sealing plate 241. A counterweight plate 2403 is inserted inside the frame 2401. A cover 2402 is fitted onto the surface of the sealing plate 241. The outer end face of the cover 2402 is on the same horizontal plane as the outward side of the cover body 10. The inner side of the cover 2402 is sleeved with the frame 2401. The cover 2402 and the frame 2401 can stably hold the counterweight plate 2403 between them. The counterweight plate 2403 is made of solid stainless steel. Its main purpose is to secure the cover 241 after it is connected to the inner sleeve 21. This increases the compaction effect and prevents the sealing plate 241 from separating from the inner sleeve 21 during bumpy conditions. At the same time, when the sealing component 24 needs to be disassembled for lighting, excessive force should be avoided when pushing the sealing plate 241 to prevent local deformation of the sealing plate 241. The outer ring wall of the frame 2401 is provided with an external thread 2404, and the inner wall of the cover 2402 is provided with an internal thread 2405. The internal thread 2405 and the external thread 2404 are threaded together, which makes it easy to remove the counterweight plate 2403 for reuse when the sealing component 24 is damaged, without having to discard the whole thing.

[0040] An annular groove 2406 is provided on the outer ring wall of the cover 2402. A sealing ring 2407 is wrapped on the inner wall of the annular groove 2406. The sealing ring 2407 is made of water-swellable rubber material. After the cover 2402 is installed in the through hole 20, the outer ring wall of the sealing ring 2407 can be tightly pressed against the inner wall of the through hole 20, thereby achieving a stable seal after the cover 2402 is assembled with the through hole 20, reducing dust and water seepage into the interior of the cover body 10 from the through hole 20.

[0041] In practice

[0042] In this solution, the hood assembly 1 achieves the opening and closing function by cooperating with the rotating shaft at the engine position of the vehicle body through the hood rotating shaft seat 11. The hood rotating shaft seat 11 and the hood body 10 adopt an integrated structure. The shaft hole 12 opened on its surface passes through the vehicle body rotating shaft, so that the hood body 10 can rotate with the rotating shaft as the fulcrum. The hood closing buffer post 13 is fixed to both ends of the inner side of the hood body 10 by screws. Its rubber material absorbs the impact force when the hood is closed, avoiding rigid collision between the hood body 10 and the vehicle body. The hood opening support seat 14 is fixed to the inner side of the front end of the hood body 10. When the hood is flipped to the open state, the support seat is inserted into the vehicle body support bar for limiting, ensuring that the hood is stably suspended during maintenance. The U-shaped structure of the lock head 16 is fixed to the middle of the front end of the hood body 10 by screws. When closed, it is inserted into the vehicle body lock groove and latched to prevent the hood from vibrating and falling off during driving.

[0043] The hood body 10 is composed of a core layer 1001, a reinforcing layer 1002, and a base layer 1003. The core layer 1001 is made of epoxy resin or vinyl ester resin, which provides an adhesive matrix and enhances corrosion resistance. The reinforcing layer 1002 is made of glass fiber, which improves impact resistance and reduces costs. The base layer 1003 is a multi-layer carbon fiber composite structure, which gives it extremely high rigidity and strength. The resin matrix bonds the carbon fibers together, making the hood lightweight while having excellent mechanical properties. The glass fiber layer compensates for the brittleness of the carbon fibers and prevents cracking under extreme impact.

[0044] The through-hole 20 is extended for installation and edge protection via the built-in sleeve 21. The built-in sleeve 21 is bolted to the inner wall of the cover body 10 via the annular protruding mounting hole 23. The mounting ring 22 welded inside provides a positioning screw contact for the lamp holder, preventing cracking of the through-hole 20 edge due to direct installation. The sealing assembly 24 achieves quick installation and removal through the sliding insertion of the insert 242 and the slot 245: the spring 244 inside the insert 242 drives the locking pin 243 to compress during insertion until it engages with the arc-shaped groove 245. After alignment, the 47 springs into lock; during disassembly, external force pushes the sealing plate 241, causing the locking pin 243 to be pressed out of the arc groove 247. The counterweight plate 2403 is clamped and fixed to the cover 2402 by the frame 2401. The stainless steel material increases the stability of the sealing plate 241 and prevents it from being dislodged by bumps. The cover 2402 is sealed by screwing the internal thread 2405 and the external thread 2404 together. The water-swellable sealing ring 2407 in its annular groove 2406 expands after being exposed to moisture, further preventing dust and rainwater from seeping in.

[0045] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
