Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a lightweight modified fender bracket. Background Technology

[0002] The fender is an important part of the car body, used to cover the wheels. The fender is fixed to the car body by the fender bracket. The existing fender brackets are mostly made of metal, which is too heavy and does not meet the needs of vehicle lightweighting modification. In addition, the existing fender brackets are mostly fixed by bolt connection. When the vehicle needs to be repaired or modified, the operation of disassembling and installing the fender bracket is cumbersome and requires tools, which is time-consuming, labor-intensive and inconvenient.

[0003] Meanwhile, in high-performance modifications or track applications, the vehicle's braking system generates high temperatures, affecting braking stability. At high speeds, high-pressure airflow also accumulates inside the wheel arches, generating excess lift. Existing fender bracket structures have a single function, only providing fixation and unable to provide additional cooling airflow to the braking system, nor can they actively guide the high-pressure air inside the wheel arches to improve aerodynamic performance.

[0004] Therefore, this utility model proposes a lightweight modified fender bracket to overcome the shortcomings of the prior art. Utility Model Content

[0006] This utility model provides a lightweight modified fender bracket, including: a shell, a cover plate, a fixing strip, and a heat dissipation pressing mechanism.

[0007] The cover plate has a locking block 1 fixed at its bottom, and the locking block 1 has a limiting groove; the fixing strip has a locking groove 2, and a compression spring is fixed in the locking groove 2. A fixing block is fixed on one side of the compression spring, and the fixing block cooperates with the limiting groove in a resilient snap-in manner.

[0008] Furthermore, the heat dissipation and pressure-down mechanism is disposed on the outer casing, and the heat dissipation and pressure-down mechanism includes a duct, a partition plate, a baffle, an air outlet, and an air nozzle; the partition plate is fixed to the inner wall of the duct, and the partition plate divides the duct into a pressure port that connects to the air outlet and a heat dissipation port that connects to the air nozzle; the baffle plate is connected to the air inlet of the duct via a hinge.

[0009] Preferably, the fixing strip has grooves on its left and right sides, a pull rod is slidably connected to the inner wall of the groove, and the fixing block is fixedly connected to the bottom of the pull rod.

[0010] Preferably, the outer wall of the pull rod is provided with a slot; the lightweight modified fender bracket also includes a hollow block, the inner wall of which is slidably connected with a second locking block, which can lock the inner wall of the slot.

[0011] Preferably, the bracket is made of carbon fiber.

[0012] Preferably, the limiting groove is formed on both sides of the first card block.

[0013] Preferably, the second slot is formed at the top of the fixing strip.

[0014] Preferably, the fixing block is fixed to the left side of the compression spring.

[0015] Preferably, the hinge is fixed to the upper and lower left ends of the air duct.

[0016] Preferably, the air outlet is located on the right side of the air duct, and the air nozzle is fixed to the left side of the air duct.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of existing fender brackets relying on tools for fixing, which leads to cumbersome, time-consuming and labor-intensive installation and disassembly processes, by setting a mechanical locking cooperation structure of cover plate, locking block, fixing strip, compression spring, fixing block, limiting groove and pull rod. The fender can be quickly installed and disassembled without tools, which greatly improves the convenience of operation.

[0019] 2. This utility model, by setting up a heat dissipation and pressure-down mechanism, uses air ducts, partitions, baffles, pressure ports, heat dissipation ports, air outlets and nozzles to guide the airflow during driving, which solves the problems of the existing technology where the fender bracket has a single function, cannot actively dissipate heat from the braking system, and neglects the optimization of aerodynamics inside the wheel arch.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 6 This utility model provides a lightweight modified fender bracket, including a shell 201, a cover plate 1, a fixing strip 12, and a heat dissipation pressing mechanism 2. A locking block 3 is fixed to the bottom of the cover plate 1. The locking block 3 has a limiting groove 6 on both sides. The fixing strip 12 has a locking groove 13 on the top. A compression spring 4 is fixed in the locking groove 13. A fixing block 7 is fixed to one side of the compression spring 4. The fixing block 7 is fixed to the left side of the compression spring 4 and can be elastically inserted into the limiting groove 6. Sliding grooves 10 are provided on the left and right sides of the fixing strip 12. A pull rod 11 is slidably connected to the inner wall of the sliding groove 10. The bottom of the pull rod 11 is fixedly connected to the fixing block 7. A locking groove 9 is provided on the outer wall of the pull rod 11.

[0031] The lightweight modified fender bracket also includes a hollow block 8. The inner wall of the hollow block 8 is slidably connected to a second locking block 5, which can lock the inner wall of the first locking slot 9. The heat dissipation pressing mechanism 2 is set on the outer shell 201. The heat dissipation pressing mechanism 2 includes a duct 202, a partition plate 205, a baffle 207, an air outlet 203, and an air nozzle 204. The inner wall of the duct 202 is fixed with a partition plate 205, which divides the duct 202 into a pressure port 208 that connects to the air outlet 203 and a heat dissipation port 209 that connects to the air nozzle 204. The air inlet of the duct 202 is connected to the baffle 207 by a hinge 206. The hinge 206 is fixed to the upper and lower left sides of the duct 202. The air outlet 203 is opened on the right side of the duct 202, and the air nozzle 204 is fixed on the left side of the duct 202. The bracket is made of carbon fiber.

[0032] Please refer to Figure 1 , Figure 3 and Figure 4 A locking block 3 is fixed to the bottom of the cover plate 1. Limiting grooves 6 are opened on both sides of the locking block 3. A fixing strip 12 is fixed on the outer shell 201. A second locking groove 13 is opened on the top of the fixing strip 12. A compression spring 4 is fixed inside the second locking groove 13. A fixing block 7 is fixed to the left side of the compression spring 4. The fixing block 7 can elastically pass through the second locking groove 13. When the cover plate 1 is installed, the cover plate 1 is pressed down. The inclined surface of the locking block 3 presses against the fixing block 7, forcing the fixing block 7 to move to the right against the elastic force of the compression spring 4, thereby causing the compression spring 4 to contract. After the locking block 3 has completely slid past the fixing block 7, the fixing block 7 returns to the left under the action of the elastic force of the compression spring 4 and is pressed against the inner wall of the limiting groove 6, thus completing the locking between the cover plate 1 and the fixing strip 12.

[0033] Please refer to Figure 4 and Figure 5 The left and right sides of the fixing strip 12 are provided with sliding grooves 10. The inner wall of the sliding groove 10 is slidably connected to the pull rod 11. The bottom of the pull rod 11 is fixedly connected to the fixing block 7. When it is necessary to remove the cover plate 1, the pull rod 11 is slid outward. The pull rod 11 drives the fixing block 7 to slide outward synchronously through the fixed connection relationship, so that the fixing block 7 is disengaged from the limiting groove 6. At this time, the fixing block 7 is no longer engaged with the locking block 3, and the cover plate 1 can be lifted upward and removed. The outer wall of the pull rod 11 is provided with a locking groove 9. A hollow block 8 is also fixed on the outer shell 201. The inner wall of the hollow block 8 is slidably connected to the locking block 5. After the pull rod 11 is pulled out to the unlock position, the locking block 25 is slid, so that the locking block 25 is locked with the inner wall of the locking groove 9, which can prevent the pull rod 11 from being accidentally reset.

[0034] Please refer to Figure 1 , Figure 2 and Figure 6The heat dissipation and pressure mechanism 2 is installed on the outer shell 201. The heat dissipation and pressure mechanism 2 includes a duct 202. A partition plate 205 is fixed on the inner wall of the duct 202. The partition plate 205 divides the duct 202 into an upper pressure port 208 and a lower heat dissipation port 209. A hinge 206 is fixed at the upper and lower ends of the left side of the air inlet of the duct 202. A baffle 207 is rotatably connected to the hinge 206. When the vehicle is running, the airflow in front blows the baffle 207 to rotate inward around the hinge 206, so that cold air enters the pressure port 208 and the heat dissipation port 209 respectively. The cold air entering the pressure port 208 flows along the duct 202 and is discharged from the air outlet 203 opened on the right side of the duct 202, so that the outer shell 201 is pressed down as a whole. The cold air entering the heat dissipation port 209 flows along the duct 202 and is discharged from the air nozzle 204 fixed on the left side of the duct 202, directly cooling the brake disc.

[0035] As a preferred embodiment, please refer to Figure 4 In order to enable the controllable movement of the fixing block 7 for unlocking, the left and right sides of the fixing strip 12 are provided with sliding grooves 10. The inner wall of the sliding groove 10 is used to slide the pull rod 11. The bottom of the pull rod 11 is connected to the fixing block 7 by a fixed connection.

[0036] As another preferred embodiment, please refer to Figure 4 and Figure 5 In order to keep the lever 11 in the unlocked position, the outer wall of the lever 11 is provided with a slot 9, and a hollow block 8 is fixed on the outer shell 201. The inner wall of the hollow block 8 is slidably connected with a second block 5, which can be inserted into the inner wall of the slot 9 for temporary fixation.

[0037] As a preferred embodiment, in order to achieve lightweight support, the outer shell 201, cover plate 1, fixing strip 12, air duct 202 and baffle 207 are all made of carbon fiber.

[0038] As a preferred embodiment, please refer to Figure 3 In order to achieve stable engagement, the limiting groove 6 is specifically opened on both sides of the locking block 3 to accommodate the insertion of the fixing block 7.

[0039] As a preferred embodiment, please refer to Figure 4 The second slot 13 is specifically opened on the top of the fixing strip 12 to accommodate the installation and sliding of the compression spring 4 and the fixing block 7.

[0040] As a preferred embodiment, please refer to Figure 4 The fixing block 7 is specifically fixed to the left side of the compression spring 4, so that when the cover plate 1 is installed, the fixing block 7 is pressed to the right and compresses the compression spring 4.

[0041] As a preferred embodiment, please refer to Figure 2 and Figure 6 In order to enable the baffle 207 to rotate flexibly, the hinge 206 is specifically fixed to the upper and lower ends of the left side of the air duct 202, and the baffle 207 is rotatably connected to the hinge 206.

[0042] As a preferred embodiment, please refer to Figure 2 In order to distinguish the paths of the two airflows, the air outlet 203 is specifically opened on the right side of the air duct 202 to discharge the airflow from the pressure port 208, and the air nozzle 204 is specifically fixed on the left side of the air duct 202 to discharge the airflow from the heat dissipation port 209 to the brake disc.

[0043] Working principle:

[0044] When the cover plate 1 needs to be installed, press the cover plate 1 down. The locking block 3 fixed to the bottom of the cover plate 1 will press the fixing block 7, which will cause the fixing block 7 to move inward against the elastic force of the compression spring 4 fixed in the slot 13 and cause the compression spring 4 to retract. When the locking block 3 slides to the bottom, the fixing block 7 will be pressed back to its original position by the rebounding compression spring 4 and locked into the inner wall of the limiting groove 6 opened on both sides of the locking block 3, thus realizing the quick locking of the cover plate 1 and the fixing strip 12.

[0045] When disassembly is required, the pull rod 11, which is slidably connected to the inner wall of the left and right side sliding grooves 10 of the fixing strip 12, is slid outward. The pull rod 11 drives the fixing block 7 to move synchronously, so that the fixing block 7 is disengaged from the limiting groove 6. At this time, the fixing block 7 no longer engages with the locking block 3, and the cover plate 1 can be disassembled upward. Then, the locking block 5 on the inner wall of the hollow block 8 is slid, so that the locking block 5 engages with the inner wall of the locking groove 9 opened on the outer wall of the pull rod 11, thereby fixing the pull rod 11 in the pulled-out position. This realizes the quick installation and disassembly of the fender, which is convenient for operation. The bracket is made of carbon fiber material, which greatly reduces the weight and achieves lightweighting.

[0046] When the vehicle is started, the cooling downforce mechanism 2 is activated. The airflow in front rotates the baffles 207 connected to the upper and lower left ends of the air duct 202 via the hinge 206, allowing cold air to enter the air duct 202. The partition plate 205 fixed to the inner wall of the air duct 202 divides the air duct 202 into a pressure port 208 and a heat dissipation port 209. The cold air enters the pressure port 208 and the heat dissipation port 209 respectively. The cold air entering the pressure port 208 is discharged from the air outlet 203 on the right side of the air duct 202, causing the outer shell 201 to be pressed down as a whole. The cold air entering the heat dissipation port 209 is discharged from the air nozzle 204 fixed to the left side of the air duct 202, directly cooling the brake disc. This achieves cooling during operation and also helps to increase the downforce of the vehicle body.
