[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0038] like Figure 1 As shown, the brake disc protective cover 100 of the embodiment of the utility model includes a cover body 1. The material of the cover body 1 can be metal such as stainless steel. The cover body 1 is sheet-shaped as a whole, and the cover body 1 is an integral structure and can be processed and formed by casting, stamping, etc.

[0039] The cover body 1 is provided with an outer flange 11, which is provided at the outer peripheral edge of the cover body 1 and folded toward the side of the cover body 1 away from the brake disc 200, and the outer flange 11 is used to guide the airflow 400 to flow between the cover body 1 and the brake disc 200. Figures 1 to 3 As shown, the outer flange 11 can be integrally formed on the outer peripheral edge of the cover body 1, the outer flange 11 can be folded to the left side of the cover body 1, and the brake disc 200 can be provided on the right side of the cover body 1.

[0040] When in use, under the guidance of the flange, the airflow 400 can enter between the cover body 1 and the brake disc 200, thereby achieving an air-cooling effect on the brake disc 200, avoiding heat accumulation and overtemperature of the brake disc 200, thereby enhancing the heat dissipation of the brake disc 200, which is beneficial to extending the service life of the brake disc 200 and the stability of use.

[0041] In some embodiments, the cover body 1 is provided with a protrusion 12 , which protrudes toward the side of the cover body 1 away from the brake disc 200 and limits the air inlet channel 19 on the other side of the cover body 1 , and the outer flange 11 is provided at the outer peripheral edge of the protrusion 12 .

[0042] For example, Figure 2 and Figure 3 As shown, the protrusion 12 can be processed by stamping, and the protrusion 12 as a whole can be fan-shaped. The protrusion 12 can protrude to the left side of the cover body 1, and the right side part of the cover body 1 corresponding to the protrusion 12 can form a groove structure, which is the air inlet channel 19. The above-mentioned outer flange 11 can be integrally formed at the air inlet of the air inlet channel 19.

[0043] When in use, the airflow 400 guided by the outer flange 11 can directly flow into the air inlet channel 19. The setting of the air inlet channel 19 can increase the gap between the cover body 1 and the brake disc 200, thereby also having a certain flow guidance effect and facilitating the airflow 400 to flow between the cover body 1 and the brake disc 200.

[0044] In some embodiments, the air inlet channel 19 includes a first channel wall 191 and a second channel wall 192 arranged relatively to each other in the extension direction of the cover body 1, the outer flange 11 is located between the first channel wall 191 and the second channel wall 192, and the distance between the first channel wall 191 and the second channel wall 192 gradually increases along the direction from the inside to the outside of the cover body 1.

[0045] For example, Figure 4 As shown, the cover body 1 as a whole can be C-shaped, that is, the cover body 1 is arc-shaped and extends in a curved manner along the circumferential direction. The first channel wall 191 and the second channel wall 192 can both be prismatic structures formed by the protrusion 12 during stamping. The first channel wall 191 and the second channel wall 192 both extend generally along the radial direction of the cover body 1, wherein the first channel wall 191 can be located above the second channel wall 192, and the above-mentioned air inlet channel 19 is formed between the first channel wall 191 and the second channel wall 192.

[0046] like Figure 2 As shown, the spacing between the first channel wall 191 and the second channel wall 192 in the up-down direction gradually increases from front to back, thereby making the size of the inlet of the air inlet channel 19 larger, thereby facilitating the air flow 400 to further flow into the air inlet channel 19, fully ensuring the air intake volume, and further improving the overall air-cooling heat dissipation effect.

[0047] In some embodiments, the angle formed by the first channel wall 191 and the second channel wall 192 is 100 degrees to 180 degrees. Figure 4 As shown, the angle formed by the first channel wall 191 and the second channel wall 192 can be angle α, and the angle α can be 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, 180 degrees, etc., thereby fully ensuring the air intake.

[0048] Preferably, the angle α may be 103 degrees.

[0049] In some embodiments, the cover body 1 is provided with a plurality of heat dissipation holes 13 penetrating the cover body 1 along the thickness direction of the cover body 1, and in the extension direction of the cover body, some of the heat dissipation holes 13 are located on one side of the protrusion 12, and some of the heat dissipation holes 13 are located on the other side of the protrusion 12.

[0050] For example, Figure 2 As shown, a plurality of heat dissipation holes 13 are provided, and each heat dissipation hole 13 can be a long hole. A portion of the heat dissipation holes 13 can be located above the protrusion 12, and another portion of the heat dissipation holes 13 can be located below the protrusion 12.

[0051] When in use, after entering the air inlet channel 19, the airflow 400 can flow upward and downward respectively along the extension direction of the cover body 1, so that a part of the airflow 400 can be discharged through the heat dissipation holes 13 located above the protrusion 12, and another part of the airflow 400 can be discharged through the heat dissipation holes 13 located below the protrusion 12. The airflow 400 between the cover body 1 and the brake disc 200 can be guided out through the heat dissipation holes 13, thereby improving the heat exchange efficiency.

[0052] In some embodiments, some heat dissipation holes 13 are configured as a hole group 14, and the hole group 14 includes a plurality of heat dissipation holes 13 arranged at intervals along the extension direction of the cover body 1. Figure 2 As shown, there may be two hole groups 14, one of which may be located above the protrusion 12, and the hole group 14 may include five heat dissipation holes 13 arranged in parallel and spaced apart along the front-to-back direction, and the other hole group 14 may be located below the protrusion 12, and the hole group 14 may include three heat dissipation holes 13 arranged in parallel and spaced apart.

[0053] The multiple heat dissipation holes 13 of each hole group 14 are arranged at intervals along the extension direction of the cover body 1 (the circumferential direction of the center of the brake disc 200). Therefore, when the brake disc 200 rotates at a high speed relative to the cover body 1, more airflow 400 can be exported through the heat dissipation holes 13, thereby further improving the heat exchange efficiency.

[0054] In some embodiments, Figure 2 As shown, the cover body 1 is provided with a plurality of first convex bumps 15, and the first convex bumps 15 are arranged along the thickness direction of the cover body 1 ( Figure 2 The first convex bump 15 is convex to one side of the cover body 1 (in the left and right direction) and forms a groove on the other side of the cover body 1. For example, the first convex bump 15 can be generally L-shaped, trapezoidal, etc., and the shape of the first convex bump 15 can be designed according to actual needs.

[0055] A portion of the first convex bump 15 may protrude to the left side of the cover body 1 and form a groove on the right side of the cover body 1, and another portion of the first convex bump 15 may protrude to the right side of the cover body 1 and form a groove on the left side of the cover body 1. The design of the first convex bump 15 can enhance the local structural strength of the cover body 1, and the formed groove can be used to avoid other structural parts, thereby improving the convenience of installation.

[0056] A heat dissipation hole 13 is provided between at least two adjacent first convex bumps 15. Figure 2 As shown, at least one heat dissipation hole 13 may be provided between any two adjacent first convex bumps 15 located above the protruding portion 12 , thereby further increasing the derived airflow 400 .

[0057] In some embodiments, the cover body 1 is provided with an inner flange 18 for inserting into the inner hole of the brake disc 200 . The inner flange 18 is extended along the inner peripheral edge of the cover body 1 . The folding direction of the inner flange 18 is opposite to that of the outer flange 11 .

[0058] For example, Figure 2 As shown, the cover body 1 as a whole can be C-shaped, and the inner flange 18 can be provided at the inner peripheral edge of the cover body 1. The inner flange 18 can be folded to the right side of the cover body 1. Since the existing brake disc 200 is annular, during assembly, the inner flange 18 can be inserted into the inner hole of the brake disc 200, and the inner flange 18 can block the air inlet channel 19 toward the inner side of the cover body 1, thereby preventing the airflow 400 from flowing out along the air inlet channel 19.

[0059] In some embodiments, the cover body 1 is provided with a plurality of second convex bumps 16 , which protrude toward the side of the cover body 1 away from the brake disc 200 , and each second convex bump 16 is provided with a mounting hole 161 for mounting and fixing the cover body 1 to the steering knuckle 500 .

[0060] For example, Figure 2 As shown, three second convex bumps 16 may be provided, and the three second convex bumps 16 may all protrude to the left side of the cover body 1. The three second convex bumps 16 may be arranged at intervals along the extension direction of the cover body 1, and one of the convex bumps may be provided at the protruding portion 12. Each second convex bump 16 may be provided with a mounting hole 161, and the mounting hole 161 may be passed through by fasteners such as bolts, thereby facilitating the connection and fixation between the cover body 1 and the steering knuckle 500 of the suspension system of the vehicle.

[0061] In some embodiments, the cover body 1 is provided with a convex rib 17, and the convex rib 17 extends along the extension direction or the width direction of the cover body 1. Figure 2 As shown, the rib 17 may protrude to the left side of the cover body 1, and the rib 17 may be arranged to extend along the circumference of the cover body 1. The provision of the rib 17 may enhance the local structural strength.

[0062] The brake assembly of the embodiment of the utility model is described below.

[0063] The brake assembly of the embodiment of the utility model comprises a brake disc 200 and a brake disc protective cover 100. The brake disc protective cover 100 may be a brake disc protective cover 100 as described in any of the above embodiments, and the protective cover is arranged on the inner side of the brake disc 200. For example, Figure 5 As shown, the brake disc 200 may be a brake disc 200 for a wheel on the right side of the vehicle. In this case, the protective cover may be disposed on the left side of the brake disc 200 (the inner side of the brake disc 200 ).

[0064] In some embodiments, the distance between the brake disc 200 and the brake disc shield 100 is 5 mm to 20 mm. Figure 5 As shown, the brake disc 200 and the brake disc protective cover 100 can be arranged at intervals in the left-right direction and the distance between the two can be a distance L, and the distance L can be 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, etc. It should be noted that the distance L can also be regarded as a size requirement for the air inlet channel 19. Within this numerical range, the air intake volume can be guaranteed, and the situation that the distance between the brake disc 200 and the brake disc protective cover 100 is too narrow or too wide can be avoided.

[0065] The following describes a vehicle according to an embodiment of the present invention.

[0066] The vehicle of the embodiment of the utility model includes a brake assembly, and the brake assembly can be a brake assembly as described in any of the above embodiments. The vehicle can be a car, SUV, bus and other vehicles, and of course can also be other vehicles that need to be equipped with a brake assembly.

[0067] When the vehicle is moving, Figure 6 As shown, an airflow 400 will be formed at the bottom of the chassis of the vehicle, and the airflow 400 will flow into the space between the brake disc 200 and the brake disc protective cover 100 through the gap between the air duct 300 and the outer flange 11 of the brake disc protective cover 100. The brake disc 200 can be cooled by air by the flowing airflow 400, and the airflow 400 after heat exchange can flow out through the various heat dissipation holes 13 on the brake disc protective cover 100.
