[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0031] In this disclosure, unless otherwise stated, directional words such as "up, down, left, right, front, and rear" refer to the up, down, left, right, front, and rear of a vehicle under normal use. Figure 1 The terms used, such as "first" and "second", are only used to distinguish one element from another element and do not have sequential and importance.

[0032] Reference Figures 1 to 2 As shown, the present disclosure provides a vehicle, which includes a brake disc 1, a suspension arm 2, a chassis 3 and a heat dissipation duct component 4. The heat dissipation duct component 4 is arranged on the suspension arm 2, and a through heat dissipation duct 40 is formed inside the heat dissipation duct component 4. The first air duct opening 401 of the heat dissipation duct 40 is arranged forward and at least partially protrudes downward from the lower surface of the chassis 3, so that the air flow below the chassis 3 flows into the heat dissipation duct 40. The second air duct opening 402 of the heat dissipation duct 40 is opposite to the brake disc 1 and is arranged at a distance.

[0033] In the above technical solution, a heat dissipation duct component 4 with a heat dissipation duct 40 formed therein is provided on the suspension arm 2, and the first duct opening 401 of the heat dissipation duct 40 is arranged forward and at least partially protrudes downward from the lower surface of the chassis 3. When the vehicle is in motion, the airflow below the chassis 3 can enter the heat dissipation duct 40 through the first duct opening 401 and can flow out through the second duct opening 402. Since the second duct opening 402 is opposite to the brake disc 1 and is arranged at a distance, the airflow flowing out of the second duct opening 402 can blow toward the brake disc 1, thereby effectively dissipating the heat of the brake disc 1, improving the convective heat transfer coefficient of the brake disc 1, and improving driving safety.

[0034] In one embodiment, reference Figure 1 and Figure 2 As shown, the periphery of the first air duct opening 401 includes a first enveloping edge 4011 and a second enveloping edge 4012. The first enveloping edge 4011 is connected to the front side of the second enveloping edge 4012 and is located above the second enveloping edge 4012. The first enveloping edge 4011 defines a first notch 403 with an opening facing forward, and the second enveloping edge 4012 defines a second notch 404 with an opening facing downward. The first notch 403 and the second notch 404 are interconnected and together define the first air duct opening 401.

[0035] In this embodiment, the second envelope edge 4012 defines a downwardly facing second notch 404, effectively reducing the weight of the heat dissipation duct member 4 and preventing excessive weight from interfering with the normal operation of the suspension arm 2. The first envelope edge 4011 defines a forwardly facing first notch 403. This first notch 403 at least partially protrudes downward from the lower surface of the chassis 3 to allow airflow into the heat dissipation duct 40, thereby dissipating heat from the brake disc 1. Furthermore, the first notch 403 and the second notch 404 can be configured in any suitable shape, which is not limited by this disclosure.

[0036] For example, refer to Figure 1 and Figure 2 As shown, the first envelope edge 4011 includes a first edge segment 4013, a second edge segment 4014, and a third edge segment 4015. The first edge segment 4013 extends in the left-right direction, while the second edge segment 4014 and the third edge segment 4015 are connected to the left and right ends of the first edge segment 4013 and extend downward. The second envelope edge 4012 is constructed as a semi-enclosed edge. The front side of the semi-enclosed edge includes a first front end 4016 and a second front end 4017, which are spaced apart in the left-right direction. The lower end of the second edge segment 4014 is connected to the first front end 4016, and the lower end of the third edge segment 4015 is connected to the second front end 4017. The first envelope edge 4011 and the second envelope edge 4012 can effectively increase the diameter of the first air duct opening 401, thereby increasing the air intake of the first air duct opening 401, but the present disclosure does not limit the peripheral shape of the first air duct opening 401.

[0037] Optionally, refer to Figure 2 As shown, the above-mentioned second envelope edge 4012 is gradually protruded downward in the direction from front to back. When the second notch 404 defined by the second envelope edge 4012 protrudes downward from the lower surface of the chassis 3, in addition to reducing the weight of the heat dissipation duct component 4, it can also stop the airflow on the lower surface of the chassis 3 and guide it into the heat dissipation duct 40, further increasing the air intake.

[0038] In other embodiments, the upper edge of the first air duct opening 401 is arranged to be located above or flush with the lower surface of the chassis 3 ; the lower edge of the first air duct opening 401 is located below the lower surface of the chassis 3 .

[0039] In this embodiment, the upper edge of the first air duct opening 401 is arranged to be located above or flush with the lower surface of the chassis 3, ensuring that air can enter the first air duct opening 401. Specifically, when the upper edge of the first air duct opening 401 is arranged flush with the lower surface of the chassis 3, the first air duct opening 401 is completely located below the lower surface of the chassis 3, thereby ensuring that the first air duct opening 401 has the largest air inlet surface. Furthermore, the lower edge of the first air duct opening 401 is located below the lower surface of the chassis 3, also ensuring that at least a portion of the first air duct opening 401 is located below the lower surface of the chassis 3, ensuring that the first air duct opening 401 can take in air under any operating conditions.

[0040] Taking the specific shape of the first air duct opening 401 as an example, the upper edge of the first air duct opening 401 is the first edge section 4013 , and the lower edge of the first air duct opening 401 is the rear end of the second envelope edge 4012 .

[0041] Furthermore, it should be noted that when the vehicle is in motion (including normal driving, acceleration, and braking), the suspension arm 2 will perform corresponding movements, which can be roughly understood as reciprocating motion in the vertical direction of the vehicle relative to the chassis 3. Since the heat dissipation duct member 4 is also provided on the suspension arm 2, it will also reciprocate in the vertical direction of the vehicle relative to the chassis 3 along with the suspension arm 2. Furthermore, the heat dissipation duct member 4 of the present disclosure can ensure that airflow enters the heat dissipation duct 40 through the first duct opening 401, regardless of whether it is in the upper or lower limit position.

[0042] For example, when the vehicle is under maximum braking, the heat dissipation duct member 4 moves to the lower limit position along with the suspension arm 2. Under this condition, the upper edge of the first air duct opening 401 (i.e., the first edge section 4013 in this embodiment) is flush with the lower surface of the chassis 3, thereby ensuring maximum air intake under maximum braking conditions. Furthermore, because the upper edge of the first air duct opening 401 does not protrude downward from the lower surface of the chassis 3, airflow is prevented from flowing toward the outer surface of the heat dissipation duct member 4, which would cause flow loss and increase resistance.

[0043] When the vehicle is in the maximum acceleration condition, the heat dissipation duct member 4 moves to the upper limit position following the suspension swing arm 2. Under this condition, the lower edge of the first duct opening 401 (i.e., the rear end of the second envelope edge 4012 in the specific embodiment) is also located below the lower surface of the chassis 3, ensuring that under this condition, air can enter the heat dissipation duct 40 through the first duct opening 401, and the brake disc 1 can also be cooled.

[0044] Optionally, the upper edge of the first air duct opening 401 (i.e., the first edge segment 4013 in the specific embodiment) is set to have a dimension between 22 mm and 28 mm in the vertical direction relative to the lower surface of the chassis 3 when the vehicle is in a driving condition of 120 km / h; and the lower edge of the first air duct opening 401 (i.e., the rear end of the second envelope edge 4012 in the specific embodiment) is set to have a dimension between 9 mm and 15 mm in the vertical direction relative to the lower surface of the chassis 3 when the vehicle is in a driving condition of 120 km / h.

[0045] For example, when the vehicle is traveling at a speed of 120 km / h: the size of the upper edge of the first air duct opening 401 and the lower surface of the chassis 3 in the vertical direction is 22 mm, and the size of the lower edge of the first air duct opening 401 and the lower surface of the chassis 3 in the vertical direction is 9 mm; or, the size of the upper edge of the first air duct opening 401 and the lower surface of the chassis 3 in the vertical direction is 25 mm, and the size of the lower edge of the first air duct opening 401 and the lower surface of the chassis 3 in the vertical direction is 12 mm; or, the size of the upper edge of the first air duct opening 401 and the lower surface of the chassis 3 in the vertical direction is 28 mm, and the size of the lower edge of the first air duct opening 401 and the lower surface of the chassis 3 in the vertical direction is 15 mm, but the present disclosure does not limit the specific dimensions.

[0046] In addition, the size of the first air duct opening 401 in the left-right direction is between 90 mm and 110 mm, and the size of the first air duct opening 401 in the front-to-back direction is between 90 mm and 110 mm. For example, the size of the first air duct opening 401 in the left-right direction is 90 mm, and the size in the front-to-back direction is also 90 mm; or the size of the first air duct opening 401 in the left-right direction is 100 mm, and the size in the front-to-back direction is also 100 mm; or the size of the first air duct opening 401 in the left-right direction is 110 mm, and the size in the front-to-back direction is also 110 mm.

[0047] Reference Figure 1 and Figure 2 As shown, the heat dissipation duct member 4 includes a heat dissipation duct member body 41 and at least one mounting portion 42. The heat dissipation duct member body 41 has a heat dissipation duct 40 formed therein. The mounting portion 42 is disposed on the heat dissipation duct member body 41 and is removably connected to the suspension arm 2, facilitating installation and removal of the heat dissipation duct member 4. For example, the mounting portion 42 is configured as two mounting bosses, each having a first mounting hole formed therein, and the suspension arm 2 having a second mounting hole formed therein. Fasteners are inserted through the first and second mounting holes to removably attach the heat dissipation duct member 4 to the suspension arm 2.

[0048] The heat dissipation duct member 4 disclosed herein can be constructed as an integrally formed structure to ensure the overall structural strength of the heat dissipation duct member 4 .

[0049] In addition, the above-mentioned brake disc 1 can be constructed as a rear wheel brake disc, and the above-mentioned suspension swing arm 2 can be constructed as a rear suspension upper swing arm or a rear suspension lower swing arm, so that the heat dissipation duct component 4 can be used to dissipate heat from the rear wheel brake disc, thereby improving the braking heat dissipation performance of the rear wheel brake disc.

[0050] In addition, the corresponding chassis 3 may include a chassis body (not shown) and a bottom guard plate 31 , and the bottom guard plate 31 is arranged on the lower surface of the chassis body; wherein the lower surface of the above-mentioned chassis 3 is the lower surface of the bottom guard plate 31 .

This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
