Description

TECHNICAL FIELD

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

[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 improve fuel consumption and electricity consumption under high-speed working conditions. In addition, tire resistance accounts for about 30% of the total vehicle resistance. Due to the tire facing the incoming flow and its own rotation, the airflow in the wheel cavity is turbulent and forms vortex, resulting in energy loss.

[0003] In high-speed driving, 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 inhibiting the generation of tire vortex and reducing the wind resistance of the whole vehicle. In actual application, the higher the height of the front wheel air dam, the more significant the drag reduction effect. However, due to the requirements of the passability and approach angle of the vehicle, 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 the reduction of the heat dissipation efficiency of the brake system, the continuous rise of the brake temperature, and thus the brake heat recession phenomenon, affecting the brake safety of the vehicle.

It can be understood that in other embodiments, the included 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 flow guide assembly 30 is arranged in the first gap 11, one end of the flow guide assembly 30 is rotationally connected with the first member 10, and the other end of the flow guide assembly 30 is slidingly abutted with the second member 20, that is, the flow guide assembly 30 can be moved upward away from the ground or moved downward close to the ground through rotation, the flow guide assembly 30 is matched with the first gap 11, and the bottom surface of the flow guide assembly 30 is configured in an arc shape. The driving assembly 40 is arranged in the first member 10 or the second member 20, and the driving assembly 40 is configured to drive the flow guide assembly 30 to rotate relative to the first member 10, that is, the driving assembly 40 drives the flow guide assembly 30 to move upward to be hidden between the first member 10 and the second member 20, so that there is no external protruding part below the first member 10, and meanwhile, the second gap 21 can be partially or entirely exposed according to the degree of upward movement of the flow guide assembly 30 to form an air inlet channel directly opposite the tire, when the flow guide assembly 30 moves upward, the arc-shaped bottom surface of the flow guide assembly 30 can play a role in guiding the airflow upward, thereby playing a role in braking and heat dissipation; the driving assembly 40 drives the flow guide assembly 30 to move downward to form a front wheel air dam directly opposite the tire, when the flow guide assembly 30 moves downward, the arc-shaped bottom surface of the flow guide assembly 30 can play a role in guiding the airflow downward, thereby playing a role in the air dam.

[0035] The vehicle body structure 100 of the embodiment of the present application, please see Figure 2 When it is detected that the brake system temperature of the vehicle 300 is relatively high, the driving assembly 40 drives the flow guide assembly 30 to rotate upward, the other end of the flow guide assembly 30 moves upward, that is, moves away from the ground, the second gap 21 of the second member 20 is exposed, the second gap 21 and the first gap 11 form an air inlet channel directly opposite the brake system, and since the bottom surface of the flow guide assembly 30 is in an arc shape, through the guiding action of the first gap 11, the second gap 21 and the flow guide assembly 30, the low-temperature airflow in front is guided to flow into the wheel cavity of the tire through the air inlet channel better, the flow speed of the airflow around the brake system is improved, the convective heat transfer efficiency of the brake system is improved, and the purpose of rapid heat dissipation of the brake system is achieved. Please see Figure 3 When it is detected that the vehicle 300 is running at a high speed and the brake system temperature is relatively low, the driving assembly 40 drives the flow guide assembly 30 to rotate downward, the other end of the flow guide assembly 30 moves downward, that is, moves close to the ground, the flow guide assembly 30 protrudes downward from the first member 10, and the flow guide 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 the fuel economy or the cruising range. Please see Figure 2When it is detected that the vehicle 300 is running at low speed, the driving assembly 40 drives the flow guide assembly 30 to rotate upward, the other end of the flow guide assembly 30 moves upward, that is, moves away from the ground, the flow guide assembly 30 is hidden between the first member 10 and the second member 20, and there is no external protruding part below the first member 10, thereby improving the passability of the vehicle 300. Based on this, the vehicle body structure 100 provided by the embodiment can meet the requirements of flow guiding, heat dissipation and passability of the vehicle 300.

[0036] Please refer to Figure 4 In the embodiment, the vehicle body structure 100 further comprises 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 connected with the second member 20. The first baffle 50 and the second baffle 60 are respectively located on both sides of the first gap 11 and the second gap 21, and the first baffle 50 and the second baffle 60 respectively slide against both sides of the flow guide assembly 30. Among them, the first baffle 50 and the second baffle 60 are roughly trapezoidal. In this way, by arranging the first baffle 50 and the second baffle 60 as described above, first, the first baffle 50 and the second baffle 60 guide the movement of the flow guide assembly 30, ensuring the movement accuracy of the flow guide assembly 30; second, the first baffle 50 and the second baffle 60 enhance the connection stability between the first member 10 and the second member 20, improving the strength of the vehicle body structure 100; third, the first baffle 50 and the second baffle 60 limit both sides of the air inlet channel, avoiding air flow entering the upper part of the first member 10, and ensuring the guiding accuracy of the air flow.

[0037] Please refer to Figure 5 In the embodiment, the flow guide assembly 30 comprises 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 with the first member 10, the bottom plate 32 is connected with the connecting plate 31, the number of the side plate 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 with 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 with the connecting plate 31 and the two side plates 33, and the sliding plate 35 is arranged opposite to the connecting plate 31, the sliding plate 35 is connected with the bottom plate 32, the top plate 34 and the two side plates 33. Among them, the side of the bottom plate 32 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 gap 11. In this way, by arranging the specific structure of the flow guide assembly 30 as described above, the vehicle body structure 100 has high strength and high stability, and is not easily deformed by air flow. By limiting the side of the bottom plate 32 away from the top plate 34 as an arc surface, the flow guide assembly 30 can guide the front low-temperature air flow to flow into the wheel cavity better, achieving the purpose of rapid cooling of the braking system, and in addition, the shape resistance of the flow guide vehicle body structure 100 itself can be reduced.

[0038] In the embodiment, the flow guide assembly 30 can be a solid body. It can be understood that in other embodiments, the flow guide assembly 30 can 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 limited in the embodiment.

[0039] In the embodiment, the bottom plate 32 of the flow guide assembly 30 is flush with the bottom surface of the first member 10 on the side away from the top plate 34, thereby ensuring that there is no separation of the flow from the front at the connection between the first member 10 and the flow guide assembly 30.

[0040] In the embodiment, the sliding plate 35 is protruded relative to the top plate 34, the side of the sliding plate 35 away from the connecting plate 31 is in sliding abutment with the second member 20, the side of the top plate 34 away from the bottom plate 32 is arc-shaped, 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 protruded relative to the top plate 34, when the flow guide assembly 30 moves downward, the sliding plate 35 can keep shielding the second gap 21, avoiding the formation of an air inlet passage opposite to the tire at the second gap 21, and at the same time, the flow guide assembly 30 can always abut against the second member 20 through the sliding plate 35, the sliding plate 35 plays a limiting role, thereby ensuring that the flow guide assembly 30 can be rotationally connected with the first member 10, and improving the stability of the vehicle body structure 100. By limiting the top plate 34 to be arc-shaped, the cross-sectional area of one end of the flow guide assembly 30 is reduced and the cross-sectional area of the other end of the flow guide assembly 30 is increased, which is conducive to the rotation of the flow guide assembly 30 relative to the first member 10.

[0041] In the embodiment, the vehicle body structure 100 further comprises a rotating shaft 70 and a hook 80. The rotating shaft 70 is arranged on the first member 10 and arranged on the first gap 11, the hook 80 is arranged on one end of the flow guide assembly 30, and the one end of the flow guide assembly 30 is rotationally connected with the rotating shaft 70 through the hook 80 to be rotationally connected with the first member 10, wherein the driving assembly 40 is connected with the flow guide assembly 30 to drive the flow guide assembly 30 to rotate relative to the first member 10. Specifically, the number of hooks 80 is two, and the two hooks 80 are arranged on the connecting plate 31 of the flow guide assembly 30 in a spaced manner, and the connecting plate 31 is rotationally connected with the rotating shaft 70 through the hooks 80 to realize the rotational connection with the first member 10. In this way, by arranging the rotating shaft 70 and the hook 80 as described above, the connection between the first member 10 and the flow guide assembly 30 is realized. In addition, the rotating shaft 70 and the hook 80 are used in combination with the connecting plate 31, and when the flow guide assembly 30 rotates relative to the first member 10, the connecting plate 31 abuts against the first member 10, and the connecting plate 31 can also limit the rotation angle of the flow guide assembly 30.

[0042] It can be understood that in other embodiments, the number of hooks 80 can also 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 arranged at one end of the flow guide assembly 30, that is, the rotating shaft 70 is arranged at the connecting plate 31, the clamping hook 80 is arranged at the first member 10 and arranged at the first gap 11, and one end of the flow guide assembly 30 is connected with the clamping hook 80 through the rotating shaft 70 to be rotationally connected with the first member 10, wherein the driving assembly 40 is connected with the flow guide assembly 30 to drive the flow guide assembly 30 to rotate relative to the first member 10, or the driving assembly 40 is connected with the rotating shaft 70 to drive the flow guide assembly 30 to rotate relative to the first member 10 by driving the rotating shaft 70.

It can be understood that, in other embodiments, the first component 10 can also be part of the lower vehicle body apron, and the second component 20 can also be part of the front fender, which will not be described herein again.

[0046] Referring to Figure 6 The embodiment of the present application further provides an apparatus 200. The apparatus 200 is applied to the vehicle 300, and used for meeting the requirements of the vehicle 300 in terms of air guiding, heat dissipation and passability. The apparatus 200 comprises the vehicle body structure 100, a temperature sensor 201, a speed sensor 202 and a controller 203 as described above. The temperature sensor 201 is configured to detect the temperature of the braking system of the vehicle 300. The speed sensor 202 is configured to detect the speed of the vehicle 300. The controller 203 is coupled with the driving assembly 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 for controlling the driving assembly 40 to drive the air guiding assembly 30 to move upward or downward according to the temperature value of the braking system and the speed of the vehicle 300, so as to meet the requirements of the vehicle 300 in terms of air guiding, heat dissipation and passability.

[0047] Referring to Figure 7 The method executed by the controller 203 comprises the following steps S1 to S7.

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

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

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

[0051] Step S4: generating an air guiding instruction based on the temperature value being less than the preset temperature and the speed value being greater than a preset speed.

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

[0053] Step S6: generating a passability instruction based on the temperature value being less than the preset temperature and the speed value being less than the preset speed.

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

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

[0056] In step S2, based on the principle of preferential heat dissipation, the controller 203 generates a heat dissipation instruction based on that the temperature value is greater than the preset temperature. In an embodiment, the preset temperature is, for example, 300°C, and the controller 203 judges whether the temperature value is greater than 300°C. If yes, the controller 203 generates a heat dissipation instruction based on that the temperature value is greater than 300°C. It can be understood that if no, the controller 203 performs step S4. It can be understood that the preset temperature can also be other values, which are not limited in the embodiments of the present application.

[0057] In step S3, the controller 203 sends a heat dissipation instruction to the driving assembly 40, so that the driving assembly 40 drives the flow guide assembly 30 to rotate upward. Specifically, the driving piece 42 rotates counterclockwise, driving the rotating piece 43 to rotate, the rotating piece 43 drives the first connecting rod 44 to rotate upward, the first connecting rod 44 drives the sliding piece 45 and the second connecting rod 46 to move upward, the second connecting rod 46 drives the flow guide assembly 30 to move upward, so that the second gap 21 of the second component 20 is exposed, the second gap 21 and the first gap 11 form an air inlet channel opposite to the braking system. Since the bottom surface of the flow guide assembly 30 is arc-shaped, through the guiding action of the first gap 11, the second gap 21 and the flow guide assembly 30, the low-temperature airflow in front is guided to flow into the tire cavity of the tire through the air inlet channel, the flow speed of the airflow around the braking system is improved, the convective heat transfer efficiency of the braking system is improved, so that the purpose of rapid heat dissipation of the braking system is achieved.

[0058] In step S4, the controller 203 generates a flow guide instruction based on that the temperature value is less than the preset temperature and the vehicle speed value is greater than the preset vehicle speed. In an embodiment, the preset vehicle speed is 80 km / h, and the controller 203 judges whether the vehicle speed value is greater than 80 km / h under the condition that the temperature value is less than 300°C. If yes, the controller 203 generates a flow guide instruction based on that the temperature value is less than 300°C and the vehicle speed value is greater than 80 km / h. It can be understood that if no, the controller 203 performs step S6. It can be understood that the preset vehicle speed can also be other values, which are not limited in the embodiments of the present application.

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

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

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

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