[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] like Figures 1 to 12As shown, the present application provides a vehicle (not fully illustrated), the vehicle comprising a body, a brake assembly and a guide structure, the brake assembly and the guide structure are both connected to the body, wherein the guide structure is suitable for guiding airflow to the brake assembly to dissipate heat from the brake assembly.

[0042] Specifically, the brake assembly corresponds to the tire of the vehicle one by one, one tire corresponds to one brake assembly, the guide structure corresponds to the brake assembly, and one brake assembly corresponds to one tire. The left front wheel, the right front wheel, the left rear wheel and the right rear wheel each have a set of brake assemblies and a guide structure corresponding to the brake assembly.

[0043] For example, the left front wheel is equipped with a set of brake assemblies, and one set of brake assemblies corresponds to one guide structure.

[0044] It can be seen that the present application provides a guide structure corresponding to the brake assembly of each tire, so that the airflow can be directed to each brake assembly, thereby improving the overall heat dissipation performance of the vehicle.

[0045] In an optional embodiment, the brake assembly includes a brake caliper 6 and a brake disc 5 .

[0046] Specifically, when the vehicle brakes, the brake caliper 6 fixes the brake disc 5, and the guide structure guides the airflow of the brake assembly and can dissipate heat to the brake caliper 6 and the brake disc 5. In order to better dissipate heat, air vents can be opened on the brake caliper 6 and the brake disc 5, and the air vents are arranged opposite to the guide structure to enhance the heat dissipation of the brake assembly.

[0047] Furthermore, a dust cover 4 can be provided on the brake assembly. The dust cover 4 is provided toward the guide structure, and can better protect the brake assembly from dust accumulation, thereby improving the performance of the brake assembly. A vent is also provided on the dust cover 4, and the vent is provided opposite to the guide structure, thereby enhancing the heat dissipation of the brake assembly.

[0048] In an optional embodiment, the guide structure includes an air outlet, and the airflow is suitable for being guided to the brake assembly through the air outlet. In the vehicle width direction, the distance from at least part of the guide structure to the brake assembly is greater than the distance from the air outlet to the brake assembly.

[0049] Specifically, an air inlet is provided at one end of the guide structure to guide the external airflow into the guide structure, and an air outlet is provided at the other end to guide the airflow to flow toward the brake assembly. The distance from at least part of the guide structure to the brake assembly is greater than the distance from the air outlet to the brake assembly, so that at least part of the guide structure is arranged in an arc shape.

[0050] It can be seen that in the present application, by setting the guide structure to an arc shape, the airflow can be blown from the air inlet to the side of the brake assembly, thereby increasing the contact area between the airflow and the brake assembly and better performing heat exchange.

[0051] In an optional embodiment, at least part of the air guiding structure extends along the width direction of the vehicle, and / or at least part of the air guiding structure extends along the length direction of the vehicle.

[0052] Specifically, the guide structure can be arranged in a straight line along the length direction of the vehicle body, and in the length direction of the vehicle body, the airflow flows directly to the brake assembly near the front of the vehicle through the guide structure. Optionally, the guide structure can also be arranged in an arc shape, so that the airflow can be blown from the air inlet to the side of the brake assembly.

[0053] It can be seen that the guide structure in the present application can be set to a straight line or an arc shape to guide the airflow directly to the brake assembly, enhance the heat dissipation capacity of the brake assembly, and improve the braking performance of the entire vehicle.

[0054] In an optional implementation, the guide structure is disposed at the bottom of the vehicle.

[0055] Specifically, the bottom of the vehicle is a side vertical to the ground in the height direction of the vehicle.

[0056] It can be seen that the guide structure of the present application can be flexibly set and can be set at the bottom of the vehicle to guide the bottom airflow to the brake assembly.

[0057] In an optional embodiment, the vehicle is further provided with a bottom guard plate 12 at the bottom, the bottom guard plate 12 is connected to the vehicle body, and a groove which is sunken upward along the height direction of the vehicle body is provided on the bottom guard plate 12, and the groove forms the guide structure.

[0058] Specifically, the bottom guard plate 12 is installed on the vehicle body, and a groove that is upwardly concave along the height direction of the vehicle body is opened at the position where the bottom guard plate 12 is close to the tire. The groove is arranged relative to the tire, and the left front wheel, the right front wheel, the left rear wheel and the right rear wheel each correspond to a groove. The airflow at the bottom is guided to the brake assembly through the groove.

[0059] It can be seen that in the present application, by providing a groove on the bottom guard plate 12, there is no need to add other additional components, which improves the heat dissipation capacity of the brake assembly while saving costs.

[0060] In an optional embodiment, the guide structure includes a guide plate and a guide plate, the guide plate is provided with an air inlet to introduce airflow, and the guide plate is provided with an air outlet so that the airflow is suitable for guiding to the brake assembly through the air outlet.

[0061] Specifically, the guide structure includes two parts, a guide plate and a guide plate. The guide plate and the guide plate can be connected or spaced. The guide plate can be one or more, and the guide plate can be one or more. The guide plate can be a closed guide channel or an open and closed guide channel. The guide plate can be an independently set structure or a groove opened in the bottom guard plate 12. The guide plate is provided with an air inlet and an air outlet. The air inlet of the guide plate introduces airflow. The guide plate is provided with an air inlet and an air outlet. The air outlet of the guide plate outputs airflow, so that the airflow is guided to the brake assembly by the air outlet of the guide plate.

[0062] It can be seen that the present application introduces airflow through the guide plate, and then guides the airflow to the brake assembly through the guide plate, thereby improving the heat dissipation capacity of the brake assembly.

[0063] In an optional embodiment, at least part of the deflector extends along the width direction of the vehicle body; and / or; at least part of the deflector extends along the length direction of the vehicle body.

[0064] Specifically, the deflector is arranged on the vehicle body suspension, and the deflector can extend in the width direction of the vehicle body or in the length direction of the vehicle body, and can be flexibly selected according to different vehicle suspensions.

[0065] In an optional embodiment, the guide plates are spaced apart from each other along the length direction of the vehicle.

[0066] Specifically, in the length direction of the vehicle body, the guide plate is closer to the front of the vehicle than the guide plate, and the guide plate is closer to the rear of the vehicle than the guide plate. The air outlet of the guide plate is directly opposite to the air inlet of the guide plate, so that the airflow guided out from the guide plate can accurately flow into the air inlet of the guide plate.

[0067] In an optional embodiment, the vehicle includes a first guide structure and a second guide structure, the first guide structure is suitable for guiding the airflow to the brake assembly of the front wheels of the vehicle, and the second guide structure is suitable for guiding the airflow to the brake assembly of the rear wheels of the vehicle.

[0068] Specifically, according to the principle of airflow generated when the vehicle is running, a first guide structure is set on the side close to the front of the vehicle to guide the airflow in front of the vehicle to flow to the brake assembly, and a second guide structure is set on the side close to the rear of the vehicle.

[0069] It can be seen that the present application provides guide structures on both the front and rear wheels to guide the airflow to the brake assembly to the greatest extent, thereby enhancing the heat dissipation capacity of the brake assembly.

[0070] In an optional embodiment, the vehicle further includes a bottom guard plate 12, which is connected to the vehicle body and disposed at the bottom of the vehicle body. The bottom guard plate 12 of the vehicle is provided with a groove which is recessed upward in the height direction of the vehicle body, and the groove forms a second guide structure.

[0071] Specifically, the second guide structure can be a groove opened on the vehicle bottom guard plate 12 and recessed upward in the direction of the vehicle body height. The heat dissipation of the rear wheel brake assembly is guided through the groove set at the bottom, and the air flows from the groove to the guide plate. The guide plate guides the airflow introduced into the groove and the surrounding airflow to the brake assembly for heat dissipation.

[0072] It can be seen that the present application realizes the diversion of the airflow at the rear end of the vehicle by arranging a guide structure at the rear wheel of the vehicle, thereby improving the heat dissipation capacity of the rear wheel brake assembly.

[0073] In an optional implementation, the first air guide structure includes a first air guide plate 1 and a second air guide plate 2, and the first air guide plate 1 and the second air guide plate 2 are arranged at intervals along the width direction of the vehicle body.

[0074] Specifically, the front wheel of the vehicle is provided with two deflectors, and the first deflector 1 and the second deflector 2 are arranged at intervals. As shown in the figure, taking the right front wheel as an example, the air inlet of the first deflector 1 is opened on the right side of the front guard 13 of the vehicle, and the air outlet is arranged at intervals relative to the deflector, and the airflow flowing in from the front of the vehicle is introduced into the deflector. The first deflector 1 can be a groove opened inside the vehicle body, or a separately arranged drainage channel; the air inlet of the second deflector 2 is opened on the bottom guard 12 of the vehicle, and the air outlet is arranged relative to the deflector. The second deflector 2 can be a groove opened in the bottom guard 12, or an independent drainage channel installed on the bottom guard 12.

[0075] It can be seen that the present application realizes the diversion of the airflow at the front end of the vehicle by arranging a guide structure on the front wheel of the vehicle, thereby improving the heat dissipation capacity of the front wheel brake assembly.

[0076] In an optional embodiment, the guide plate of the first guide structure is a two-section guide plate 3, including an upper plate 31 and a lower plate 32, the upper plate 31 and the lower plate 32 are arranged at intervals along the width direction of the vehicle body, and the upper plate 31 and the lower plate 32 are arranged at intervals along the length direction of the vehicle body.

[0077] Specifically, the upper plate 31 is connected to the swing arm of the vehicle body suspension, and the lower plate 32 is connected to the suspension of the vehicle. The upper plate 31 and the lower plate 32 are spaced apart in the width and height directions of the vehicle body so that the upper plate 31 and the lower plate 32 will not overlap to avoid affecting the guidance of the airflow.

[0078] In an optional embodiment, along the length direction of the vehicle body, the projection of the upper plate 31 at least partially overlaps with the projection of the lower plate 32 .

[0079] Specifically, in the present application, the projections of the upper plate 31 and the lower plate 32 overlap in the length direction of the vehicle body to limit the interval between the upper plate 31 and the lower plate 32 without affecting the guidance of the airflow by the upper plate 31 and the lower plate 32 .

[0080] In an optional embodiment, the upper plate 31 includes a first air inlet end and a first air outlet end, and the lower plate 32 includes a second air inlet end and a second air outlet end. In the width direction of the vehicle body, the first air inlet end and the second air inlet end are spaced apart, and the first air outlet end and the second air outlet end are both formed as air outlets.

[0081] Specifically, the upper plate 31 and the lower plate 32 both have an air inlet end and an air outlet end. The air inlet ends of the upper plate 31 and the lower plate 32 are spaced relative to the guide plate, and the air outlet ends are spaced relative to the brake assembly, so that the airflow flowing in from the guide plate can flow to the brake assembly. As shown in the figure, in the width direction of the vehicle body, the distance from the first air outlet end to the brake assembly is smaller than the distance from the second air outlet end to the brake assembly. The upper plate 31 is installed on the swing arm of the vehicle suspension, and the swing arm is closer to the brake assembly than the vehicle body suspension. According to different types of suspensions, the distance from the first air outlet end to the brake assembly can also be greater than the distance from the second air outlet end to the brake assembly.

[0082] It can be seen that the guide structure in the present application is a two-stage guide plate 3. Since the amount of air introduced into the vehicle from the guide plate is very large when the vehicle is traveling at high speed, setting a guide plate on the suspension requires a stronger structure and a larger shape. Therefore, by adding a guide plate to the swing arm, the airflow introduced by the guide plate is shared, thereby improving the guide effect and saving costs.

[0083] In an optional embodiment, in the width direction of the vehicle, the air outlet of the deflector is arranged between two tires of the vehicle.

[0084] Specifically, the air outlet of the deflector is set between the two front wheels or the two rear wheels, and the airflow from the air outlet of the deflector blows from the inside of the vehicle to the side of the brake assembly, increasing the contact area between the airflow and the brake assembly and better heat exchange. It can be understood that the position of the air outlet of the deflector can be flexibly set according to the size and heat dissipation requirements of the vehicle, and can be directly facing the side of the brake assembly, or can be in the oblique direction relative to the brake assembly, and can be above or below the height direction of the vehicle body. This application does not limit this.
