Description

Technical Field

[0001] The present application relates to the technical field of vehicle accessories, and in particular to a vehicle body structure, assembly, device and vehicle. Background Art

[0002] With the increasingly stringent national fuel consumption regulations and pure electric endurance requirements, the development of vehicle aerodynamic performance is particularly important. Studies have shown that when the vehicle speed reaches 80km / h, about 60% of the fuel consumption is used to overcome wind resistance. Therefore, reducing wind resistance is of great significance to improving fuel consumption and power consumption under high-speed conditions. In addition, tire resistance accounts for about 30% of the total vehicle resistance. Since the tire is facing the incoming flow and rotating itself, the airflow in the wheel cavity is turbulent and forms vortices, resulting in energy loss.

[0003] When driving at high speeds, in order to reduce the wind resistance of the whole vehicle, a front wheel air dam is usually designed in front of the tire. The front wheel air dam can effectively reduce the airflow flowing into the tire, thereby suppressing the generation of tire vortex and reducing the wind resistance of the whole vehicle. In practical applications, the higher the height of the front wheel air dam, the more significant its drag reduction effect. However, due to the vehicle's passability and approach angle requirements, the height of the front wheel air dam cannot be increased indefinitely. At the same time, the increase of the front wheel air dam will reduce the airflow flowing into the wheel cavity, resulting in a decrease in the heat dissipation efficiency of the brake system and a continuous increase in the brake temperature, which in turn causes brake thermal decay and affects the braking safety of the vehicle.

[0004] Therefore, there is an urgent need to design a vehicle body structure to meet the vehicle's air flow, heat dissipation and passability requirements. Summary of the invention

[0005] In view of the above, it is necessary to propose a vehicle body structure, assembly, device and vehicle to meet the vehicle's air conduction, heat dissipation and passability requirements.

[0006] An embodiment of the present application provides a vehicle body structure, which includes a first component, a second component, a guide assembly and a drive assembly; the first component has a first notch; the second component is vertically connected to the first component, the second component has a second notch, and the second notch is connected to the first notch; the guide assembly is arranged in the first notch, one end of the guide assembly is rotatably connected to the first component, the other end of the guide assembly is slidably abutted against the second component, and the bottom surface of the guide assembly is configured as an arc surface; the drive assembly is arranged on the first component or the second component, and the drive assembly is configured to drive the guide assembly to rotate relative to the first component.

Since the bottom surface of the guide component is an arc surface, through the guiding effect of the first notch, the second notch and the guide component, the front low-temperature airflow is guided to flow into the wheel cavity of the tire through the air intake channel better, thereby increasing the flow speed of the airflow around the brake system, and improving the convective heat transfer efficiency of the brake system, so as to achieve the purpose of rapid heat dissipation of the brake system. When it is detected that the vehicle is running at a high speed and the temperature of the brake system is low, the driving component drives the guide component to rotate downward, and the other end of the guide component moves downward, that is, moves close to the ground, and the guide component protrudes downward from the first component. The guide component forms an air dam to guide the airflow to the ground, which can block the airflow flowing into the wheel cavity, reduce the flow around the wheel cavity, reduce the vehicle's driving resistance, and improve fuel economy or cruising range. When it is detected that the vehicle is traveling at a low speed, the driving component drives the air guide component to rotate upward, and the other end of the air guide component moves upward, that is, moves away from the ground. The air guide component is hidden between the first component and the second component, and there are no protruding parts under the first component, thereby improving the vehicle's passability.

[0030] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1 , the embodiment of the present application provides a vehicle body structure 100, the vehicle body structure 100 is applied to a vehicle 300 (see Figure 8 ), used to meet the flow diversion, heat dissipation and passability requirements of the vehicle 300, among which, the flow diversion requirement is used to block the airflow entering the wheel cavity of the front tire, reduce tire resistance, and play a role in energy saving and consumption reduction. The heat dissipation requirement is used to guide the front low-temperature airflow to better flow into the braking system of the vehicle 300, so as to achieve the purpose of rapid cooling and heat dissipation of the braking system. The passability requirement is used to improve the passability of the vehicle 300.

[0032] The vehicle body structure 100 includes a first component 10 , a second component 20 , a flow guide assembly 30 and a driving assembly 40 .

[0033] The first component 10 has a first notch 11, wherein the first component 10 can be a lower body guard plate of the vehicle 300, the first component 10 can also be a part of the lower body guard plate, and the first component 10 can also be connected to the lower body guard plate. The second component 20 is vertically connected to the first component 10, and the second component 20 has a second notch 21, and the second notch 21 is connected to the first notch 11, wherein the second component 20 can be a front fender of the vehicle 300, the second component 20 can also be a part of the front fender, and the second component 20 can also be connected to the front fender. The vertical connection between the second component 20 and the first component 10 can be understood as the second component 20 and the first component 10 are roughly vertically connected, and the angle between the second component 20 and the first component 10 can range from 80° to 100°, etc. It can be understood that in other embodiments, the angle between the second component 20 and the first component 10 can also be other angles, which can be set according to actual conditions.

[0034] The guide component 30 is arranged in the first notch 11, one end of the guide component 30 is rotatably connected to the first component 10, and the other end of the guide component 30 is slidably abutted against the second component 20, that is, the guide component 30 can move upward away from the ground or move downward close to the ground by rotation. The guide component 30 is adapted to the first notch 11, and the bottom surface of the guide component 30 is configured as an arc surface. The driving component 40 is disposed on the first component 10 or the second component 20, and the driving component 40 is configured to drive the guide component 30 to rotate relative to the first component 10, that is, the driving component 40 drives the guide component 30 to move upward to be hidden between the first component 10 and the second component 20, so that there are no protruding parts under the first component 10, and at the same time, according to the degree of upward movement of the guide component 30, the second notch 21 can be partially or completely exposed to form an air intake channel facing the tire. When the guide component 30 moves upward, the curved bottom surface of the guide component 30 can guide the airflow upward, thereby playing a role in braking and heat dissipation; the driving component 40 drives the guide component 30 to move downward to form a front wheel air dam facing the tire. When the guide component 30 moves downward, the curved bottom surface of the guide component 30 can guide the airflow downward, thereby playing a role in air dam.

[0035] The vehicle body structure 100 of the embodiment of the present application is shown in FIG. Figure 2 When the temperature of the brake system of the vehicle 300 is detected to be high, the driving component 40 drives the air guide component 30 to rotate upward, and the other end of the air guide component 30 moves upward, that is, moves away from the ground, so that the second notch 21 of the second member 20 is exposed. The second notch 21 and the first notch 11 form an air intake channel facing the brake system. Since the bottom surface of the air guide component 30 is an arc surface, the first notch 11, the second notch 21 and the air guide component 30 guide the front low-temperature airflow through the air intake channel to better flow into the wheel cavity of the tire, thereby increasing the flow speed of the airflow around the brake system and improving the convective heat exchange efficiency of the brake system, thereby achieving the purpose of rapid heat dissipation of the brake system. Please refer to Figure 3 When it is detected that the vehicle 300 is traveling at a high speed and the temperature of the brake system is low, the driving component 40 drives the guide component 30 to rotate downward, and the other end of the guide component 30 moves downward, that is, moves close to the ground. The guide component 30 protrudes downward from the first component 10, and the guide component 30 forms an air dam to guide the airflow to the ground, which can block the airflow flowing into the wheel cavity, reduce the flow around the wheel cavity, reduce the driving resistance of the vehicle 300, and improve the fuel economy or cruising range. See Figure 2When the vehicle 300 is detected to be traveling at a low speed, the driving assembly 40 drives the air guide assembly 30 to rotate upward, and the other end of the air guide assembly 30 moves upward, that is, moves away from the ground. The air guide assembly 30 is hidden between the first component 10 and the second component 20, and there is no protruding part under the first component 10, thereby improving the passability of the vehicle 300. Based on this, the vehicle body structure 100 provided in the embodiment of the present application can meet the air guide, heat dissipation and passability requirements of the vehicle 300.

[0036] See also Figure 4 In this embodiment, the vehicle body structure 100 further includes a first baffle 50 and a second baffle 60. The first baffle 50 and the second baffle 60 are arranged at intervals on the first member 10, and the first baffle 50 and the second baffle 60 are both connected to the second member 20. The first baffle 50 and the second baffle 60 are respectively located on both sides of the first notch 11 and the second notch 21, and the first baffle 50 and the second baffle 60 are respectively slidably abutted against both sides of the guide assembly 30. The first baffle 50 and the second baffle 60 are both substantially trapezoidal. In this way, by setting the above-mentioned first baffle 50 and second baffle 60, on the first hand, the first baffle 50 and the second baffle 60 guide the movement of the guide assembly 30 to ensure the movement accuracy of the guide assembly 30; on the second hand, the first baffle 50 and the second baffle 60 enhance the connection stability between the first component 10 and the second component 20, and improve the strength of the vehicle body structure 100; on the third hand, the first baffle 50 and the second baffle 60 form restrictions on both sides of the air intake channel to prevent the airflow from entering the top of the first component 10, thereby ensuring the guiding accuracy of the airflow.

[0037] See also Figure 5 In this embodiment, the air guide assembly 30 includes a connecting plate 31, a bottom plate 32, a side plate 33, a top plate 34 and a sliding plate 35. The connecting plate 31 is rotatably connected to the first member 10, the bottom plate 32 is connected to the connecting plate 31, the number of the side plates 33 is two, the two side plates 33 are arranged at intervals on both sides of the bottom plate 32, and the two side plates 33 are connected to both sides of the connecting plate 31, the top plate 34 is arranged opposite to the bottom plate 32, the top plate 34 is connected to the connecting plate 31 and the two side plates 33, the sliding plate 35 is arranged opposite to the connecting plate 31, and the sliding plate 35 is connected to the bottom plate 32, the top plate 34 and the two side plates 33, wherein the side of the bottom plate 32 facing away from the top plate 34 is configured as an arc surface, and the connecting plate 31, the bottom plate 32, the top plate 34 and the sliding plate 35 are all adapted to the first notch 11. In this way, by setting the specific structure of the air guide assembly 30, the vehicle body structure 100 is made strong in strength and stability, and is not easily deformed by airflow. By limiting the side of the bottom plate 32 facing away from the top plate 34 to be an arc surface, the guide component 30 can guide the front low-temperature airflow to flow into the wheel cavity better, thereby achieving the purpose of rapid cooling of the braking system. In addition, the shape resistance of the guide body structure 100 itself can be reduced.

[0038] In this embodiment, the flow guide component 30 may be a solid body. It is understandable that in other embodiments, the flow guide component 30 may also be a hollow body composed of the connecting plate 31, the bottom plate 32, the side plate 33, the top plate 34 and the sliding plate 35, which is not specifically limited in the embodiment of the present application.

[0039] In this embodiment, the side of the bottom plate 32 of the guide assembly 30 facing away from the top plate 34 is flush with the bottom surface of the first component 10 , thereby ensuring that the flow from the front will not separate at the connection between the first component 10 and the guide assembly 30 .

[0040] In this embodiment, the sliding plate 35 is relatively protruding from the top plate 34, and the side of the sliding plate 35 facing away from the connecting plate 31 is in sliding contact with the second member 20, and the side of the top plate 34 facing away from the bottom plate 32 is in an arc shape, and the top plate 34 and the bottom plate 32 have the same bending direction, and the top plate 34 and the bottom plate 32 have different bending curvatures. In this way, by limiting the sliding plate 35 to be relatively protruding from the top plate 34, when the guide assembly 30 moves downward, the sliding plate 35 can keep shielding the second notch 21, and avoid the second notch 21 from forming an intake channel facing the tire. At the same time, the guide assembly 30 can always be in contact with the second member 20 through the sliding plate 35, and the sliding plate 35 plays a limiting role, thereby ensuring that the guide assembly 30 can be rotatably connected with the first member 10, and improving the stability of the vehicle body structure 100. By limiting the top plate 34 to be in an arc shape, the cross-sectional area of ​​one end of the guide assembly 30 is reduced and the cross-sectional area of ​​the other end of the guide assembly 30 is increased, which is conducive to the rotation of the guide assembly 30 relative to the first member 10.

[0041] In this embodiment, the vehicle body structure 100 further includes a rotating shaft 70 and a hook 80. The rotating shaft 70 is disposed on the first component 10 and disposed on the first notch 11, and the hook 80 is disposed on one end of the air guide assembly 30. One end of the air guide assembly 30 is connected to the rotating shaft 70 by the hook 80 to be rotatably connected to the first component 10, wherein the driving assembly 40 is connected to the air guide assembly 30 to drive the air guide assembly 30 to rotate relative to the first component 10. Specifically, there are two hooks 80, and the two hooks 80 are arranged on the connecting plate 31 of the air guide assembly 30 at intervals, and the connecting plate 31 is connected to the rotating shaft 70 by the hook 80 to achieve a rotatable connection with the first component 10. In this way, by providing the above-mentioned rotating shaft 70 and hook 80, the connection between the first component 10 and the air guide assembly 30 is achieved. In addition, the rotating shaft 70 and the hook 80 are used in conjunction with the connecting plate 31 . When the air guide assembly 30 rotates relative to the first component 10 , the connecting plate 31 abuts against the first component 10 , and the connecting plate 31 can also limit the rotation angle of the air guide assembly 30 .

[0042] It can be understood that in other embodiments, the number of hooks 80 can be more or less, which can be set according to actual conditions.

[0043] It can be understood that in other embodiments, the rotating shaft 70 can also be disposed at one end of the guide assembly 30, that is, the rotating shaft 70 is disposed on the connecting plate 31, the hook 80 is disposed on the first member 10 and disposed at the first notch 11, and one end of the guide assembly 30 is rotatably connected to the first member 10 through the rotating connection between the rotating shaft 70 and the hook 80, wherein the driving assembly 40 is connected to the guide assembly 30 to drive the guide assembly 30 to rotate relative to the first member 10, or the driving assembly 40 is connected to the rotating shaft 70 to drive the guide assembly 30 to rotate relative to the first member 10 by driving the rotating shaft 70. When the driving assembly 40 is connected to the rotating shaft 70, the driving assembly 40 can be a motor, and the driving method of the driving assembly 40 is simple and efficient.

[0044] In this embodiment, the driving assembly 40 includes a bracket 41, a driving member 42, a rotating member 43, a first connecting rod 44, a sliding member 45 and a second connecting rod 46. The bracket 41 is arranged on the first member 10, the driving member 42 is arranged on the first member 10 and is configured by the bracket 41 to be arranged opposite to the diversion assembly 30, and the bracket 41 may be L-shaped. The rotating member 43 is connected to the driving member 42, the first connecting rod 44 is connected to the rotating member 43, the sliding member 45 is connected to the first connecting rod 44 and is away from the rotating member 43, the second connecting rod 46 is connected to the sliding member 45, and the second connecting rod 46 is connected to the diversion assembly 30, and the second connecting rod 46 is perpendicular to the first connecting rod 44. The driving member 42 is configured to drive the rotating member 43, the first connecting rod 44, the sliding member 45 and the second connecting rod 46 to rotate, so that the second connecting rod 46 drives the diversion assembly 30 to rotate relative to the first member 10. In this way, by setting the specific structure of the above-mentioned driving component 40, when the driving component 40 drives the guide component 30 to move upward, the driving member 42 rotates counterclockwise, driving the rotating member 43 to rotate, the rotating member 43 drives the first connecting rod 44 to rotate upward, the first connecting rod 44 drives the sliding member 45 and the second connecting rod 46 to move upward, and the second connecting rod 46 drives the guide component 30 to move upward; when the driving component 40 drives the guide component 30 to move downward, the driving member 42 rotates clockwise, driving the rotating member 43 to rotate, the rotating member 43 drives the first connecting rod 44 to rotate downward, the first connecting rod 44 drives the sliding member 45 and the second connecting rod 46 to move downward, and the second connecting rod 46 drives the guide component 30 to move downward.

The controller 203 is coupled to the drive component 40 of the vehicle body structure 100, the temperature sensor 201 and the speed sensor 202. The controller 203 is used to execute a method to control the drive component 40 to drive the flow diversion component 30 to move upward or downward according to the temperature value of the braking system and the vehicle speed, so as to meet the flow diversion, heat dissipation and passability requirements of the vehicle 300.

[0047] See also Figure 7 The method executed by the controller 203 includes the following steps S1 to S7.

[0048] Step S1 : receiving the temperature value detected by the temperature sensor 201 and the vehicle speed value detected by the speed sensor 202 .

[0049] Step S2: Generate a heat dissipation instruction based on the temperature value being greater than a preset temperature.

[0050] Step S3: sending a heat dissipation instruction to the driving assembly 40, so that the driving assembly 40 drives the air guide assembly 30 to rotate upward.

[0051] Step S4: Based on the temperature value being less than a preset temperature and the vehicle speed value being greater than a preset vehicle speed, a diversion instruction is generated.

[0052] Step S5: sending a diversion instruction to the driving assembly 40, so that the driving assembly 40 drives the diversion assembly 30 to rotate downward.

[0053] Step S6: Based on the temperature value being less than the preset temperature and the vehicle speed value being less than the preset vehicle speed, a passing instruction is generated.

[0054] Step S7: Send a pass instruction to the driving assembly 40, so that the driving assembly 40 drives the guide assembly 30 to rotate upward.

[0055] Specifically, in step S1, during the driving process of the vehicle 300, the temperature sensor 201 detects the temperature value of the braking system in real time and sends the temperature value to the controller 203, the speed sensor 202 detects the speed value of the vehicle 300 in real time and sends the speed value to the controller 203, and the controller 203 receives the temperature value detected by the temperature sensor 201 and the speed value detected by the speed sensor 202.

[0056] In step S2, based on the principle of priority heat dissipation, the controller 203 generates a heat dissipation instruction based on the temperature value being greater than the preset temperature. In one embodiment, the preset temperature is, for example, 300°C, and the controller 203 determines whether the temperature value is greater than 300°C. If yes, the controller 203 generates a heat dissipation instruction based on the temperature value being greater than 300°C. It is understandable that if no, the controller 203 executes step S4. It is understandable that the preset temperature can also be other values, and the embodiment of the present application does not specifically limit this.

[0057] In step S3, the controller 203 sends a heat dissipation instruction to the driving component 40, so that the driving component 40 drives the air guide component 30 to rotate upward. Specifically, the driving member 42 rotates counterclockwise, driving the rotating member 43 to rotate, the rotating member 43 drives the first connecting rod 44 to rotate upward, the first connecting rod 44 drives the sliding member 45 and the second connecting rod 46 to move upward, and the second connecting rod 46 drives the air guide component 30 to move upward, so that the second notch 21 of the second member 20 is exposed, and the second notch 21 and the first notch 11 form an air intake channel facing the brake system. Since the bottom surface of the air guide component 30 is an arc surface, through the guiding effect of the first notch 11, the second notch 21 and the air guide component 30, the low-temperature airflow in the front is guided to flow into the wheel cavity of the tire through the air intake channel better, thereby increasing the flow speed of the airflow around the brake system and improving the convective heat transfer efficiency of the brake system, thereby achieving the purpose of rapid heat dissipation of the brake system.

[0058] In step S4, the controller 203 generates a diversion instruction based on the temperature value being less than the preset temperature and the vehicle speed value being greater than the preset vehicle speed. In one embodiment, the preset vehicle speed is 80 km / h. When the controller 203 determines that the temperature value is less than 300°C, the controller 203 determines whether the vehicle speed value is greater than 80 km / h. If yes, the controller 203 generates a diversion instruction based on the temperature value being less than 300°C and the vehicle speed value being greater than 80 km / h. It is understandable that if it is not, the controller 203 executes step S6. It is understandable that the preset vehicle speed can also be other values, and the embodiment of the present application does not specifically limit this.

[0059] In step S5, the controller 203 sends a diversion instruction to the drive assembly 40, so that the drive assembly 40 drives the guide assembly to rotate downward. Specifically, the drive member 42 rotates clockwise, driving the rotating member 43 to rotate, the rotating member 43 drives the first connecting rod 44 to rotate downward, the first connecting rod 44 drives the sliding member 45 and the second connecting rod 46 to move downward, the second connecting rod 46 drives the diversion assembly 30 to move downward, the diversion assembly 30 protrudes downward from the first component 10, and the diversion assembly 30 forms an air dam to guide the airflow to the ground, which can block the airflow flowing into the wheel cavity, reduce the flow around the wheel cavity, reduce the driving resistance of the vehicle 300, and improve fuel economy or cruising range.

[0060] In step S6, the controller 203 generates a pass instruction based on the temperature value being less than a preset temperature and the vehicle speed value being less than a preset vehicle speed. In one embodiment, when the controller 203 determines that the temperature value is less than 300°C, the controller 203 determines that the vehicle speed value is less than 80 km / h, and the controller 203 generates a pass instruction based on the temperature value being less than 300°C and the vehicle speed value being less than 80 km / h.

[0061] In step S7, the controller 203 sends a passing instruction to the driving assembly 40, so that the driving assembly 40 drives the guide assembly to rotate upward. Specifically, the driving member 42 rotates counterclockwise, driving the rotating member 43 to rotate, the rotating member 43 drives the first connecting rod 44 to rotate upward, the first connecting rod 44 drives the sliding member 45 and the second connecting rod 46 to move upward, and the second connecting rod 46 drives the guide assembly 30 to move upward. The guide assembly 30 is hidden between the first component 10 and the second component 20, and there is no protruding part under the first component 10, thereby improving the passability of the vehicle 300.

[0062] It can be understood that the order of some steps in step S1 to step S7 can be changed, for example, the order of step S4 to step S5 and step S6 to step S7 can be changed, and some steps can be omitted.

The vehicle 300 also includes a vehicle body 301, and the vehicle body structure 100 is arranged on the vehicle body 301 and is arranged opposite to the front wheels. Through the above-mentioned vehicle body structure 100, the vehicle 300 takes into account the requirements of air diversion, heat dissipation and passability.
