[0053] In addition, the front and back described in the present application are based on the positional relationship that the advancing direction of the vehicle is the front and the retreating direction is the back.

[0054] For example, Figures 1-3As shown, the brake disc heat dissipation mechanism of the preferred embodiment of the present application comprises a front air guide cover 1, a front wheel cover 2 and a brake air pipe 3, the front air guide cover 1 is provided with an air inlet hole at a position opposite to the air inlet grille, the front wheel cover 2 is provided with an air outlet hole at a position opposite to the brake disc, the brake air pipe 3 comprises a pipe body 31, the two ends of the pipe body 31 are respectively provided with an air inlet 32 and an air outlet 33, the inside of the pipe body 31 is formed with a cooling air duct 310 which is in communication with the air inlet 32 and the air outlet 33, the air inlet 32 is connected with the air inlet hole, and the air outlet 33 is connected with the air outlet hole. In specific arrangement, the air inlet hole and the air outlet hole can be provided with detachable inserts, so that different vehicle configurations can be covered, for people who do not need performance areas, the air inlet hole and the air outlet hole are blocked by the inserts, and the brake air pipe 3 is not loaded, so that the cost can be reduced to attract customers, and for customers who need performance, the brake air pipe 3 is added, which not only improves the cooling performance and brake efficiency of the brake disc during vehicle driving, but also makes the vehicle more sporty.

[0055] Based on the above-mentioned brake disc heat dissipation mechanism, by arranging the brake air pipe 3, the heat dissipation effect of the brake disc can be improved, so that the driving performance of the vehicle is ensured, the cost of the automobile is avoided to be increased, and the normal endurance of the vehicle is ensured. Specifically, the brake air pipe 3 of the present application is arranged at the two ends of the pipe body 31, the air inlet 32 and the air outlet 33 are arranged at the two ends of the pipe body 31, the inside of the pipe body 31 is formed with the cooling air duct 310 which is in communication with the air inlet 32 and the air outlet 33, the air inlet 32 is connected with the front air guide cover 1, and the air outlet 33 is connected with the front wheel cover 2, so that the air flow can be introduced into the brake disc behind the pipe body 31 through the air inlet grille, the brake disc is cooled, the higher the vehicle speed, the faster the wind speed, and the more significant the cooling effect of the brake disc. Corresponding to the possible brake failure, the heat dissipation effect of the cooling disc is improved, so that the driving performance of the vehicle is ensured, and the driving accidents caused by heat recession are avoided. At the same time, the pipe body 31 only needs to be made of plastic, which not only has low cost, but also has light weight, so that not only the brake disc or large brake caliper needs to be replaced at high cost is avoided, but also the normal endurance of the vehicle is ensured.

[0056] The air inlet grille 100 is arranged at the front of the automobile, and the existing air inlet grille 100 includes an ordinary air inlet grille and an active air inlet grille. For the automobile with the ordinary air inlet grille 100, the brake disc can be cooled during vehicle driving; for the active air inlet grille 100, the brake disc can be cooled only after the active air inlet grille blades are opened.

[0057] Please refer to the drawings Figures 3-5As shown, in the embodiment, the pipe body 31 is provided with a pre-hanging part 34, which is used to connect the front end frame 4 of the vehicle. By arranging the pre-hanging part 34, the pre-hanging part 34 is connected with the front end frame 4 first during installation, and then is completely fixed through the connecting seat arranged on the pipe body 31. This not only facilitates installation, but also effectively guarantees the accuracy of installation of the brake air pipe 3.

[0058] In the embodiment, the pre-hanging part 34 includes a main body part 341, a supporting part 342 and an anti-disengagement part 343 connected in sequence, and a clamping groove 344 is formed between the main body part 341, the supporting part 342 and the anti-disengagement part 343, and the other end of the main body part 341 is connected with the pipe body 31. The front end frame 4 is provided with a hanging plate 41, and the clamping groove 344 is connected with the hanging plate 41, that is, the pre-installation of the pipe body 31 can be realized by directly connecting the clamping groove 344 with the hanging plate 41 during connection. After connection, the supporting part 342 is supported on the upper end surface of the hanging plate 41, and the anti-disengagement part 343 is hung on the inner side of the hanging plate 41, and the opposite inner surfaces of the anti-disengagement part 343 and the main body part 341 respectively abut against the two surfaces of the hanging plate 41, that is, the width or the minimum width of the clamping groove 344 is the same as the thickness of the hanging plate 41, so that the connection stability and strength between the pre-hanging part 34 and the hanging plate 41 can be guaranteed.

[0059] After the pre-installation of the pipe body 31, it needs to be completely fixed. At the same time, during the wading experiment or driving on a deep water road, water flow will flow from the front to the front wheel area along the brake air pipe 3 during rapid driving, so it is necessary to guarantee the wading strength of the brake air pipe 3, so as to guarantee the connection stability and strength thereof.

[0060] Please refer to the accompanying drawings Figure 6 , 7The brake disc heat dissipation mechanism further comprises a first support 5, a second support 7 and a crash beam 6 connected to the front end frame 4, and the first support 5 and the second support 7 are both sheet metal structures. The pipe body 31 is provided with a connecting seat (a wind pipe dog hole structure), and the connecting seat is provided with a connecting hole. Specifically, the connecting seat comprises a first connecting seat 35 provided on the front outer wall of the pipe body 31 and a second connecting seat 36 provided on the rear outer wall of the pipe body 31, and the pre-hanging part 34 is arranged between the first connecting seat 35 and the second connecting seat 36. The two ends of the first support 5 are connected to the crash beam 6 and the front end frame 4 respectively, and the middle part of the first support 5 is connected to the connecting hole of the first connecting seat 35. The two ends of the second support 7 are both connected to the front end frame 4, and the middle part of the second support 7 is connected to the connecting hole of the second connecting seat 36. The supports are connected to the front end frame 4 and the crash beam 6 by bolts and pull lugs; the supports are connected to the connecting seat by screws and spring leaves to ensure the stability of the connection. The brake wind pipe 3 is connected by the middle pre-hanging part 34, and the front and rear are fixed by sheet metal supports, which not only improves the tightening operation rhythm, but also considers the rigidity and strength of the wind pipe during high-speed driving and water driving.

[0061] During specific operation, the pre-hanging part 34 is first hung on the hanging plate 41, and then the pre-hanging part 34 is tightened on the pull lug on the hanging plate 41 of the front end frame 4 by a bolt; then the first support 5 is fixed on the first connecting seat 35 by two screws and spring leaves, and the upper end of the first support 5 is fixed on the pull lug below the crash beam 6, and the lower end of the first support 5 is fixed on the front end frame 4, such as Figure 6 ; finally, the second support 7 is fixed on the second connecting seat 36 by two screws and spring leaves, and the upper and lower ends of the second support 7 are fixed and tightened on the pull lug on the front end frame 4, such as Figure 7 . After being connected and fixed in the above manner, even under the conditions of large flow of water and high speed of wind, the wind pipe will not fall off or break.

[0062] Of course, the pipe body 31 can also be directly fixed by screws or welding, but welding requires the use of metal, which is more expensive and heavier than plastic, and is generally not used.

[0063] The tube body 31 can be integrally injection-molded or blow-molded, but preferably, the tube body 31 is formed by snapping together two half-tubes 311, secured by a locking member, with a leak-proof assembly provided between the two half-tubes 311. Using two half-tubes 311 allows for the creation of a large-diameter air duct, effectively directing airflow from the front during driving directly to the brake disc, achieving a rapid cooling effect. The two half-tubes 311 are configured as upper and lower half-tubes, and by providing a leak-proof assembly, airflow can be prevented from escaping from the upper and lower dividing areas, ensuring effective heat dissipation for the brake disc.

[0064] In this embodiment, the leak-proof assembly includes a side plate 312 provided on one side of the half-tube 311 and a gusset plate 313 provided on the other side of the half-tube 311. The gusset plate 313 is fastened to the side plate 312. In a specific embodiment, the gusset plate 313 and the side plate 312 can be integrally formed with the corresponding half-tube 311. The fastening between the gusset plate 313 and the side plate 312 ensures a tight seal between the two half-tubes 311. Specifically, the gusset plate 313 includes an abutment portion 3131 and a leak-proof portion 3132. The side of the side panel 312 facing the gusset plate 313 is a fitting surface, and the side surface of the side panel 312 away from the half-tube 311 is an abutment surface. When the gusset plate 313 is connected to the side panel 312, the abutment portion 3131 fits against the fitting surface, and the leak-proof portion 3132 abuts against the fitting surface. Under the dual action of the abutment portion 3131 and the leak-proof portion 3132, a good seal is achieved between the two half-tubes 311. In addition, a sealing ring can be provided between the abutment portion 3131 and the fitting surface to further enhance the sealing effect.

[0065] Please see the attached Figure 3 In this embodiment, the locking assembly includes a holder 330 provided on one of the half-tubes 311 and a buckle 320 provided on the other half-tube 311. The buckle 320 engages with the holder 330. Specifically, the buckle 320 corresponds to the holder 330 and is provided on two different half-tubes 311. Specifically, the holder 320 can be provided on both sides of one of the half-tubes 311; or the holder 330 can be provided on both sides of one of the half-tubes 311; or the holder 320 can be provided on one side of one of the two half-tubes 311 and the holder 330 on the other side. Furthermore, the holder 330 and the buckle 320 can be directly provided on the side panel 312 and the buckle plate 313, respectively.

[0066] In addition, for the convenience of connecting the two half pipes 311, one of the half pipes 311 is provided with a positioning hole, and the other half pipe 311 is provided with a positioning pin 340 which is inserted into the positioning hole, that is, when the two half pipes 311 are buckled, the positioning pin 340 is inserted into the corresponding positioning hole, and then the two half pipes 311 are buckled under the guidance of the positioning pin 340, thereby ensuring the connection accuracy between the two half pipes 311. When arranged, one positioning hole and one positioning pin 340 form a group, and the positioning hole and the positioning pin 340 in the group can be arranged on the side plate 312 and the buckle plate 313 respectively.

[0067] Please refer to the accompanying drawings Figure 8 In the embodiment, in order to ensure that the air flow from the front of the vehicle does not run, the edge of the outer periphery of the air inlet 32 is provided with a first ring 37, the first ring 37 is connected with the front air deflector 1, and a sealing element 8 is arranged between the first ring 37 and the front air deflector 1. The sealing element 8 is preferably foam, which is matched by die cutting, so as to ensure that the air flow is fully introduced into the air duct even considering the assembly and manufacturing deviation through the interference of foam with a certain compression ratio. In normal installation, the center line of the cooling air duct 310 coincides with the center of the air inlet, and the surface of the first ring 37 is parallel to the plane where the air inlet is arranged. Since the first ring 37 extends away from the pipe body 31, the first ring 37 completely covers the air inlet under the action of the first ring 37, thereby ensuring the overall aesthetics. However, in actual installation, the position of the pipe body 31 relative to the air inlet may deviate, but since the first ring 37 has a certain width, the air inlet can still be completely covered, so that even if the position of the pipe body 31 relative to the air inlet deviates during installation, the overall appearance will not have a step difference in vision, thereby ensuring the quality feeling.

[0068] Please refer to the accompanying drawings Figure 9In the embodiment, to ensure that the airflow flowing into the pipe body 31 can blow to the brake disc completely, the edge of the outer periphery of the air outlet is provided with a second ring 38, and the connection part between the second ring 38 and the pipe body 31 is provided with a sealing groove 39. The brake disc heat dissipation mechanism further comprises a cover plate 9, the cover plate 9 comprises a plate body 91, the plate body 91 is provided with an air guide opening, the inner wall of the air guide opening is provided with an annular sealing plate 92, the second ring 38 and the plate body 91 are connected to the front wheel cover 2, and the front wheel cover 2 is located between the second ring 38 and the plate body 91 and is connected by screws. After being connected, the sealing plate 92 is connected with the sealing groove 39 through the air outlet hole, the sealing groove 39 is completely filled, the perfect fit between the cover plate 9 and the front wheel cover 2 is realized, so that the airflow from the air outlet hole can blow to the brake disc directly, the invalid wind loss is avoided, and the heat dissipation effect is ensured.

[0069] To solve the above technical problems, the application further provides a vehicle, which comprises the brake disc heat dissipation mechanism. The air inlet grille 100 is installed at the rear of the front bumper beam 6, and the front air guide cover 1 and the rear air guide cover are fixed on the front end frame 4 by clamping and screwing. Based on the vehicle, the heat dissipation effect of the brake disc can be effectively improved, so that the driving performance of the vehicle is ensured, the cost of the vehicle is not increased too much, and the normal endurance of the vehicle is ensured.

[0070] The above is only the preferred embodiment of the application, and it should be pointed out that, for ordinary skilled persons in the technical field, some improvements and replacements can be made without departing from the technical principles of the application, and these improvements and replacements should be regarded as the protection scope of the application.
