TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a protection structure, a suspension and a vehicle. BACKGROUND

[0002] With the development of vehicles, energy consumption of vehicles has become one of the core competences of vehicles. With the increase of vehicle speed, the energy consumption of vehicles will increase significantly. When the vehicle speed is greater than 80 KPH, about 60% of the power is needed to overcome wind resistance, which shows the importance of wind resistance to vehicle energy consumption.

[0003] During the driving of the vehicle, the bottom of the vehicle also needs to overcome wind resistance. In the prior art, a cover plate is arranged at the bottom area of the tail of the vehicle, the bottom area of the tail of the vehicle is covered by the cover plate, so as to reduce the pressure difference between the front and the rear of the vehicle to reduce wind resistance.

[0004] However, during the driving of the vehicle, the wind resistance at the swing arm of the suspension is large, which leads to the increase of energy consumption of the vehicle. CONTENT OF THE UTILITY MODEL

[0005] One of the purposes of the present application is to provide a protection structure to solve the problem of large wind resistance at the swing arm of the suspension in the prior art; the second purpose is to provide a suspension; and the third purpose is to provide a vehicle.

[0006] In order to achieve the above-mentioned purposes, the technical scheme adopted by the present application is as follows:

[0007] In a first aspect, a protection structure is provided, which is used for protecting the swing arm of the suspension on the vehicle. The protection structure comprises a protection bottom plate and a first protection plate. The protection bottom plate is adapted to be connected below the swing arm of the suspension. The first protection plate is adapted to cover the front end face of the swing arm of the suspension along the length direction of the vehicle, the first protection plate is connected with the protection bottom plate and forms a containing space. The included angle between the first protection plate and the protection bottom plate is greater than 90° and less than 180°.

[0008] According to the above technical means, when the vehicle is driving, the first protection plate can guide the airflow entering the swing arm area to below the protection bottom plate, so as to accelerate the airflow flowing through the swing arm area. In this way, the wind resistance can be reduced, the energy required to overcome the wind resistance can be reduced, and the cruising range of the vehicle can be improved.

[0009] In a possible implementation, the included angle between the first protection plate and the protection bottom plate is greater than 90° and less than 150°.

[0010] According to the above technical means, the angle greater than 90° can avoid that the protection structure is too flat to affect its strength and installation stability. The included angle less than 150° can reasonably arrange the protection structure in limited space, and the protection structure will not occupy too much space due to the too large included angle.

[0011] In a possible implementation, the protection structure comprises a first arc-shaped plate. The first protection plate is connected to the protection bottom plate through the first arc-shaped plate. The first arc-shaped plate is arched towards a direction away from the accommodation space.

[0012] According to the technical means described above, the first arc-shaped plate is arched towards a direction away from the accommodation space, which can provide a smooth transition surface for the airflow. When the airflow flows from the first protection plate to the protection bottom plate, the arc-shaped plate can make the airflow change direction more smoothly, reduce the sudden change and turbulence of the airflow, avoid the formation of vortex or the generation of greater resistance at the turning point, thereby further reducing the wind resistance and improving the cruising range of the vehicle.

[0013] In a possible implementation, the first arc-shaped plate comprises a first region, a second region and a third region. The first region is connected to the protection bottom plate. The second region is connected to the first protection plate. The third region is located between the first region and the second region. The arc radius of the first region is greater than that of the third region, and the arc radius of the second region is greater than that of the third region.

[0014] According to the technical means described above, the first region, the third region and the second region cooperate to guide the airflow to form a relatively smooth flow field, avoiding the formation of large turbulence in the suspension swing arm region, thereby further reducing the wind resistance.

[0015] In a possible implementation, the protection structure further comprises a second protection plate. The second protection plate is adapted to cover the rear end surface of the suspension swing arm along the length direction of the vehicle, and the second protection plate is connected to the protection bottom plate. The included angle between the second protection plate and the protection bottom plate is greater than 90° and less than 180°.

[0016] According to the technical means described above, when the airflow flows through the suspension swing arm, the first protection plate guides the airflow to enter, and the second protection plate helps the airflow to orderly flow out at the rear end. In cooperation with the first protection plate, the airflow can pass through the suspension swing arm region more smoothly, thereby reducing the wind resistance and improving the cruising range of the vehicle.

[0017] In a possible implementation, the shape and size of the accommodation space are adapted to the shape and size of the suspension swing arm.

[0018] According to the technical means described above, the accommodation space is designed according to the actual shape and size of the suspension swing arm, which can reduce the space occupation under the vehicle chassis under the premise of meeting the protection and airflow guiding functions.

[0019] In a possible implementation, the vehicle comprises a wheel. The protection structure further comprises a first end and a second end along the width direction of the vehicle, the first end is connected to the wheel through the suspension swing arm, and the height of the first end is lower than that of the second end.

[0020] According to the above technical means, when the vehicle is running, the airflow flows from the front to the rear of the vehicle. Due to the low height of the first end, the airflow can flow more smoothly from the wheel area to the bottom of the protection structure and then flow along the protection structure to the second end. The inclined structure can guide the airflow to form a downward and rearward flow trend, reduce the accumulation and turbulence of the airflow in the wheel and suspension swing arm area, reduce the wind resistance, and thus improve the endurance mileage of the vehicle.

[0021] In a possible implementation, the protection structure further comprises a drainage port, and the drainage port is located at the first end.

[0022] According to the above technical means, the drainage port can quickly drain the water accumulated in the protection structure, avoid water accumulation from causing corrosion to the suspension swing arm and other components, and prolong the service life of the components.

[0023] In a second aspect, a suspension for a vehicle is provided. The suspension comprises a suspension swing arm and the protection structure according to any one of the embodiments of the first aspect. The protection bottom plate of the protection structure is connected below the suspension swing arm. The first protection plate of the protection structure covers the front end surface of the suspension swing arm along the length direction of the vehicle.

[0024] In a third aspect, a vehicle is provided, which comprises the protection structure according to any one of the embodiments of the first aspect or the suspension according to any one of the embodiments of the second aspect.

[0025] Advantages of the present application:

[0026] (1) When the vehicle is running, the first protection plate can guide the airflow entering the suspension swing arm area and guide it to the bottom of the protection bottom plate, so that the airflow accelerates through the suspension swing arm area. In this way, the wind resistance can be reduced, the energy required to overcome the wind resistance can be reduced, and thus the endurance mileage of the vehicle can be improved;

[0027] (2) The first arc-shaped plate is arched towards the direction away from the containing space, which can provide a smooth transition surface for the airflow.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments provided by the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0042] The present application also can be implemented or applied through other different specific embodiments, and each detail in the present application can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, but not for limiting the protection scope of the present application.

[0043] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and the drawings only show the components related to the present application, but are not drawn according to the number, shape and size of the components in actual implementation. The shape, number and proportion of each component in actual implementation can be randomly changed, and the layout pattern of the components can be more complex.

[0044] In the present application, the length direction of the vehicle, the width direction of the vehicle and the height direction of the vehicle are well known to those skilled in the art. In the drawings, the length direction of the vehicle is represented by the letter X, the width direction of the vehicle is represented by the letter Y, and the height direction of the vehicle is represented by the letter Z.

[0045] As shown in Figure 1 , the present application provides a protection structure 10 for protecting a suspension swing arm 20 on a vehicle.

[0046] As shown in Figure 2 , Figure 3 and Figure 4 , the protection structure 10 includes a protection bottom plate 1 and a first protection plate 2. The protection bottom plate 1 is adapted to be connected below the suspension swing arm 20. The first protection plate 2 is adapted to cover the front end face of the suspension swing arm 20 along the length direction of the vehicle, and the first protection plate 2 is connected with the protection bottom plate 1 and forms a containing space 4. The included angle between the first protection plate 2 and the protection bottom plate 1 is greater than 90° and less than 180°.

[0047] The protection bottom plate 1 can protect the lower surface of the suspension swing arm 20. The containing space 4 is used for containing the suspension swing arm 20.

[0048] The first protection plate 2 can protect the front end face of the suspension swing arm 20. For example, during the driving of the vehicle, stones, sand and other debris on the road surface will be splashed at high speed due to the rolling of the wheels. The first protection plate 2 can block these debris from directly impacting the front end face of the suspension swing arm 20. The first protection plate 2 can also block the airflow from directly impacting the front end of the suspension swing arm 20.

[0049] The first protection plate 2 is inclined away from the suspension swing arm 20 along the direction of the height of the vehicle and the direction upward from the protection bottom plate 1.

[0050] When the vehicle is running, the first protection plate 2 can guide the airflow entering the area of the suspension swing arm 20. The airflow turbulence and separation at the front end of the suspension swing arm 20 are reduced, and the airflow is guided below the protection bottom plate 1, so that the airflow accelerates through the area of the suspension swing arm 20. In this way, the wind resistance is reduced, the energy required to overcome the wind resistance is reduced, and the cruising range of the vehicle is improved.

[0051] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, and before the embodiments of the present application are described in detail, the application scenarios of the embodiments of the present application are first introduced.

[0052] The protection structure 10 provided by the present application is used for protecting the suspension swing arm 20 on the vehicle.

[0053] The present application also provides a suspension. The suspension provided by the present application can be an independent suspension or a non-independent suspension. The independent suspension includes but is not limited to a double wishbone suspension and a multi-link suspension. The non-independent suspension includes but is not limited to a torsion beam suspension and a leaf spring suspension.

[0054] The suspension provided by the present application can be a front suspension of a vehicle or a rear suspension of a vehicle.

[0055] The present application also provides a vehicle. The vehicle includes an electric vehicle using electric power as energy, a fuel vehicle, a hydrogen energy vehicle, a hybrid vehicle, etc. The vehicle can also be a sedan, an SUV, an MPV, a sports car, a racing car, a truck, an engineering vehicle, a special vehicle, etc. which needs to be installed with a suspension.

[0056] The vehicle includes the protection structure 10 or the suspension provided by the present application.

[0057] The suspension includes the suspension swing arm 20 and the protection structure 10. The protection bottom plate 1 of the protection structure 10 is connected below the suspension swing arm 20. The first protection plate 2 of the protection structure 10 covers the front end surface of the suspension swing arm 20 along the length direction of the vehicle.

[0058] Illustratively, the connection mode of the protection bottom plate 1 and the suspension swing arm 20 includes but is not limited to bolt connection, clamping, insertion, locking connection, magnetic connection, gluing, welding or one-piece forming.

[0059] Continuing to refer to Figure 1 and Figure 2For example, the protective bottom plate 1 is provided with mounting holes 11 at both ends in the width direction of the vehicle. The protective structure 10 further comprises bolts, and the protective bottom plate 1 is fixed to the suspension swing arm 20 by the bolts. By fixing with the bolts, the protective bottom plate 1 can be stably connected with the suspension swing arm 20, and meanwhile, the protective bottom plate 1 can be conveniently disassembled.

[0060] In a possible implementation, the protective bottom plate 1 comprises a flow guide area and a connecting area, and the connecting area is located at both sides of the flow guide area in the width direction of the vehicle, and the mounting holes 11 are located in the connecting area.

[0061] For example, the size B (see FIG. 1) of the flow guide area in the width direction of the vehicle can be correspondingly set according to the length of the suspension swing arm 20. Specifically, the length of the flow guide area in the width direction of the vehicle is greater than or equal to 250 mm and less than or equal to 350 mm. Figure 2 ) can be correspondingly set according to the length of the suspension swing arm 20. Specifically, the length of the flow guide area in the width direction of the vehicle is greater than or equal to 250 mm and less than or equal to 350 mm.

[0062] For example, the length of the flow guide area in the width direction of the vehicle can be one of 250 mm, 280 mm, 300 mm, 320 mm, and 350 mm.

[0063] For example, the protective bottom plate 1 is further provided with mounting holes 12 between the mounting holes 11. The protective structure 10 further comprises screws, and the screws connect the protective bottom plate 1 and the suspension swing arm 20.

[0064] For example, the mounting holes 12 can be counterbore structures.

[0065] It should be noted that the number of connection positions of the protective bottom plate 1 and the suspension swing arm 20 can be multiple, and is not limited to two or three.

[0066] In a possible implementation, the first protective plate 2 is integrally formed with the protective bottom plate 1, and the first protective plate 2 is made by a process of bending and flanging.

[0067] The size of the first protective plate 2 in the height direction of the vehicle can be correspondingly adjusted according to the size of the suspension swing arm 20, so that the first protective plate 2 covers the front end surface of the suspension swing arm 20 in the length direction of the vehicle.

[0068] For example, the size of the first protective plate 2 in the height direction of the vehicle is greater than or equal to 30 mm and less than or equal to 70 mm. Specifically, the size of the first protective plate 2 in the height direction of the vehicle can be one of 30 mm, 40 mm, 50 mm, 60 mm, and 70 mm.

[0069] Continuing to refer to Figure 2 , Figure 3 and Figure 4 , in a possible implementation, the included angle between the first protective plate 2 and the protective bottom plate 1 is greater than 90° and less than 150°.

[0070] The included angle between the first protective plate 2 and the protective bottom plate 1 (see Figure 4 the included angle D) is greater than 90°, so as to avoid the airflow being not smoothly guided due to the too small angle, and enable the airflow to be guided to below the protective bottom plate 1 at a certain oblique angle. The included angle is less than 150°, so as to reasonably arrange the protective structure 10 in limited space, and avoid occupying too much space due to the too large included angle.

[0071] For example, the included angle between the first protective plate 2 and the protective bottom plate 1 can be one of 91°, 100°, 110°, 120°, 130°, 140° and 150°.

[0072] Continuously referring to Figure 3 In a possible implementation, the protective structure 10 includes a first arc-shaped plate 5. The first protective plate 2 is connected with the protective bottom plate 1 through the first arc-shaped plate 5. The first arc-shaped plate 5 is arched towards a direction away from the accommodation space 4.

[0073] The first arc-shaped plate 5 is arched towards a direction away from the accommodation space 4, which can provide a smooth transition surface for the airflow. When the airflow flows from the first protective plate 2 to the protective bottom plate 1, the arc-shaped plate can make the airflow change direction more smoothly, reduce the sudden change and turbulence of the airflow, avoid the airflow forming vortex or generating large resistance at the turning point, thereby further reducing the wind resistance and improving the endurance mileage of the vehicle.

[0074] The arc-shaped structure has better mechanical properties than the straight line connection. Therefore, the first arc-shaped plate 5 can also increase the stability of the connection between the first protective plate 2 and the protective bottom plate 1.

[0075] Continuously referring to Figure 3 In a possible implementation, the first arc-shaped plate 5 includes a first region 51, a second region 52 and a third region 53. The first region 51 is connected with the protective bottom plate 1. The second region 52 is connected with the first protective plate 2. The third region 53 is located between the first region 51 and the second region 52. The arc-shaped radius of the first region 51 is greater than that of the third region 53, and the arc-shaped radius of the second region 52 is greater than that of the third region 53.

[0076] The arc-shaped radius of the second region 52 is greater than that of the third region 53, and the second region 52 is connected with the first protective plate 2, so as to make the airflow from the first protective plate 2 transition more smoothly and flow to the second region 52.

[0077] The arc-shaped radius of the first region 51 is greater than that of the third region 53, and the first region 51 is connected with the protective bottom plate 1. In this way, the airflow of the second region 52 can flow more smoothly to below the protective bottom plate 1.

[0078] In this way, the second region 52, the third region 53, and the first region 51 cooperate together to guide the airflow to form a relatively smooth flow field, so that the airflow is more attached to the protection bottom plate 1, reduces the disturbance of the airflow at this position, and improves the flow rate and stability of the airflow. Thus, the wind resistance is further reduced.

[0079] When the wind resistance is reduced, the energy consumption for overcoming the wind resistance is further reduced, and the cruising range of the vehicle is improved.

[0080] It should be noted that the greater the arc radius, the more gentle the connection between the first arc-shaped plate 5 and the protection bottom plate 1 and the first protection plate 2, and the smoother the airflow flows.

[0081] Continuing to refer to Figure 3 and Figure 4 In a possible implementation, the protection structure 10 further includes a second protection plate 3. The second protection plate 3 is adapted to cover the rear end face of the suspension swing arm 20 along the length direction of the vehicle, and the second protection plate 3 is connected with the protection bottom plate 1. The included angle between the second protection plate 3 and the protection bottom plate 1 is greater than 90° and less than 180°.

[0082] The second protection plate 3 can protect the rear end face of the suspension swing arm 20. The second protection plate 3 can block the debris, mud and the like on the road from splashing onto the suspension swing arm 20, reduce the corrosion and wear of the suspension swing arm 20 by these debris, and prolong the service life of the suspension swing arm 20.

[0083] When the airflow flows through the suspension swing arm 20, the second protection plate 3 helps the airflow to orderly flow out at the rear end, cooperates with the first protection plate 2, and makes the airflow more smoothly pass through the region of the suspension swing arm 20, reduces the resistance of the airflow, thereby reduces the wind resistance and improves the cruising range of the vehicle.

[0084] For example, the included angle between the second protection plate 3 and the protection bottom plate 1 can be one of 91°, 100°, 110°, 120°, 130°, 140°, and 150°.

[0085] Continuing to refer to Figure 3 and Figure 4 For example, the protection structure 10 includes a second arc-shaped plate 6. The second protection plate 3 is connected with the protection bottom plate 1 through the second arc-shaped plate 6. The second arc-shaped plate 6 is arched towards the direction away from the accommodation space 4.

[0086] The implementation and beneficial effects of the second arc-shaped plate 6 can be referred to the first arc-shaped plate 5, and will not be repeated here.

[0087] Continuing to refer to Figure 4 In a possible implementation, the shape and size of the accommodation space 4 are adapted to the shape and size of the suspension swing arm 20.

[0088] During the driving of the vehicle, due to the uncertainty of the wind direction, a part of the airflow can flow into the gap between the protective structure 10 and the suspension swing arm 20. The shape and size of the accommodation space 4 are adapted to the shape and size of the suspension swing arm 20, so as to reduce the gap between the protective structure 10 and the suspension swing arm 20. In this way, the airflow turbulence in the accommodation space 4 can be reduced, thereby reducing the wind resistance.

[0089] It should be noted that this arrangement will not hinder the suspension swing arm 20 from interfering with the protective structure 10 within its normal range of motion.

[0090] The accommodation space 4 is designed according to the actual shape and size of the suspension swing arm 20, so as to reduce the space occupation under the vehicle chassis while meeting the protection and airflow guiding functions.

[0091] Continuing to refer to Figure 5 In a possible implementation, the vehicle includes a wheel. The protective structure 10 further includes a first end 7 and a second end 8 along the width direction of the vehicle, the first end 7 is connected to the wheel through the suspension swing arm 20, and the height of the first end 7 is lower than the height of the second end 8.

[0092] During the driving of the vehicle, the airflow flows from the front to the rear of the vehicle. Due to the low height of the first end 7 and the proximity to the wheel, the airflow can flow more smoothly from the vicinity of the wheel into the space below the protective structure 10, and then flow along the protective structure 10 to the second end 8. This inclined structure can guide the airflow to form a downward and rearward flow trend, reduce the accumulation and turbulence of the airflow in the area of the wheel and the suspension swing arm 20, and reduce the wind resistance, thereby improving the cruising range of the vehicle.

[0093] The low first end 7 close to the wheel helps to lower the center of gravity of the vehicle. After the center of gravity of the vehicle is lowered, the stability and maneuverability of the vehicle can be improved during driving, especially during turning or high-speed driving, thereby reducing the roll and sway, and further improving the safety and comfort of driving and riding.

[0094] For example, when the height of the first end 7 is lower than the height of the second end 8. The protective structure 10 intersects with a horizontal plane, and the included angle between the protective structure 10 and the horizontal plane (see angle C in Figure 5 may be greater than or equal to 30° and less than or equal to 40°.

[0095] For example, the included angle between the protective structure 10 and the horizontal plane can be any one of 30°, 32°, 34°, 36°, 38°, and 40°.

[0096] The lower first end 7 than the second end 8 is also beneficial for drainage and removal of debris in the accommodation space.

[0097] Continuing to refer to Figure 2In a possible implementation, the protection structure 10 further comprises a drainage port 9, which is located at the first end 7.

[0098] During the driving of the vehicle, the accumulated water on the road surface can enter the protection structure 10. Due to the height difference, the accumulated water is more likely to gather at the first end 7. Through the drainage port 9, the accumulated water can be drained from the drainage port 9. The residual of the accumulated water in the protection structure 10 is reduced, the risk of corrosion and damage to the components such as the suspension swing arm 20 is reduced, and the service life of the components is prolonged.

[0099] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
