[0101] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0102] According to the first aspect of the present application, referring to Figures 1 to 6 As shown, a vehicle-mounted air guide device 100 is provided, comprising: an air guide 110, an adjustment component 120 and a rotating drive component 130. The air guide 110 is integrated in the wheel cavity 11 of the vehicle chassis 12. The wheel cavity 11 of the vehicle chassis 12 mentioned in the present application refers to the space formed by the chassis 12 and the body envelope of the vehicle, and the space is used for the installation and placement of the wheel 13, that is, the wheel 13 of the vehicle is integrated in the wheel cavity 11. The air guide 110 is movably arranged in the wheel cavity 11, and is used to guide the flow direction of the airflow in the wheel cavity 11 by changing its own position, for example, making the flow velocity of the airflow in the wheel cavity 11 relatively faster, so that the air pressure at the chassis 12 is reduced, thereby increasing the wind resistance during the driving of the vehicle, and achieving the purpose of adjusting the wind resistance encountered by the vehicle during driving.
[0103] Reference Figure 1 and Figure 2 As shown, the adjustment assembly 120 is movably connected to the guide member 110, and is used to couple the guide member 110 to the wheel cavity 11 of the vehicle chassis 12. The rotary drive member 130 is used to drive the adjustment assembly 120 to rotate relative to the vehicle chassis 12 around the first rotation axis L1, so that the guide member 110 can rotate around the first rotation axis L1 and change its position at the wheel cavity 11 of the vehicle chassis 12.
[0104] Like this, by movably installing the deflector 110 on the adjusting assembly 120, and at the same time the adjusting assembly 120 can rotate relative to the chassis 12 under the drive of the rotating drive member 130, the freedom of movement of the deflector 110 is increased, and in the limited activity space area of the wheel cavity 11, the area where the deflector 110 can be movable in the wheel cavity 11 is higher, so that during the driving process of the vehicle, according to different driving conditions of the vehicle, such as turning, emergency braking at high speed, etc., the deflector 110 can flexibly adjust the wind resistance of the vehicle by adjusting its position in the wheel cavity 11 and its active position relative to the adjusting assembly 120, so as to meet the different needs of the vehicle for wind resistance adjustment under different driving conditions.
[0105] In some embodiments, reference Figure 2 and Figure 3 As shown, the adjustment assembly 120 includes: a movable member 121. The movable member 121 and the rotary drive member 130 form a connection for transmitting a force, so that the movable member 121 rotates around the first rotation axis L1 under the drive of the rotary drive member 130. In a specific solution, the rotary drive member 130 is, for example, a motor or other device, which provides power to rotate the movable member 121 around the first rotation axis L1. The movable member 121 can be a plate-shaped part, the surface of which is arranged parallel to the surface of the chassis 12, so as to reduce its own influence on the wind resistance of the vehicle when it is driving.
[0106] The guide member 110 is movably connected to the movable member 121 to form a follow-up connection with the movable member 121. In this way, the guide member 110 can move relative to the movable member 121, for example, to a position inclined to the chassis 12, so as to guide the airflow to flow in the wheel cavity 11. The airflow velocity increases and the air pressure in the wheel cavity 11 decreases. Under the influence of the air pressure difference between the upper and lower sides of the vehicle, the resistance encountered by the vehicle during driving increases, which facilitates the vehicle to perform emergency braking and other actions. In this application, this method of adjusting the resistance encountered by the vehicle during driving is also called adjusting the wind resistance encountered by the vehicle during driving.
[0107] The movable part 121 can drive the guide member 110 to rotate around the first rotation axis L1, so that the position of the guide member 110 at the wheel cavity 11 changes. In this way, in usage scenarios such as when the wheel 13 turns, the position of the guide member 110 can change with the rotation of the movable part 121 without interfering with the normal turning of the vehicle. It also makes it possible to control the resistance encountered by the vehicle when turning and adjusting the vehicle's driving through the guide member 110.
[0108] In some embodiments, the adjustment assembly 120 further includes: a support member 122. The support member 122 is mechanically connected to the movable member 121 to couple the movable member 121 to the wheel cavity of the vehicle chassis. In this way, the support member 122 is used to provide a force to the movable member 121 to stably install the movable member 121 on the vehicle, which is equivalent to using the support member 122 to support the movable member 121 so that the movable member 121 is stably installed on the vehicle.
[0109] In a specific solution, one end of the support member 122 is fixed to the suspension 15 of the vehicle, for example, by threaded connection, welding, etc., so that the movable member 121 is rotatably installed on the vehicle suspension 15, thereby realizing the integrated installation of the adjustment component 120 on the vehicle.
[0110] In some embodiments, reference Figure 3As shown, the movable member 121 is provided with a guide groove 121a. Among them, the guide groove 121a is for at least a part of the support member 122 to be embedded, so that the support member 122 is positioned and installed on the movable member 121. In this way, the mutual engagement of the support member 122 and the movable member 121 is achieved by the mutual engagement of the guide groove 121a and the support member 122, and the guide groove 121a can cooperate with the support member 122 to guide the moving direction of the movable member 121, so that the movable member 121 can move stably.
[0111] As an exemplary description of a specific scheme, the guide groove 121a extends along an arc path, that is, when the movable part 121 rotates, the support part 122 moves along an arc relative to the movable part 121, and the center of the arc falls on the first rotation axis L1, so as to limit the relative movement direction of the support part 122 and the movable part 121 when the rotating driving part 130 drives the movable part 121 to rotate.
[0112] In some embodiments, the movable member 121 is further provided with an avoidance groove 121b. The avoidance groove 121b is connected to the guide groove 121a. At least part of the support member 122 extends out of the guide groove 121a from the avoidance groove 121b, so that the part of the support member 122 extending out of the guide groove 121a from the avoidance groove 121b can be integrated with the vehicle, and at the same time, during the relative movement between the support member 122 and the movable member 121, the avoidance groove 121b avoids the active area of the support member 122, so that the movable member 121 moves normally.
[0113] In some embodiments, the groove width of the avoidance groove 121b is smaller than the groove width of the guide groove 121a to prevent the portion of the support member 122 located in the guide groove 121a from detaching from the avoidance groove 121b. In this way, the cooperation between the avoidance groove 121b and the guide groove 121a enables the support member 122 to lift the movable member 121, thereby utilizing the support member 122 to stably install the movable member 121 on the vehicle.
[0114] In some embodiments, reference Figure 3As shown, the support member 122 includes at least two support portions 122a. The support portion 122a is located outside the guide groove 121a and is used to fix the support member to the vehicle; the at least two support portions 122a are arranged at intervals. The at least two support portions 122a support the movable member 121 at different positions of the movable member 121, so that the movable member 121 is more stably integrated on the vehicle. Considering that there are too many support portions 122a, the length of the corresponding avoidance groove 121b for the support member 122 to be placed also needs to be increased to ensure that the movable part 121 can have a larger rotation angle, which will undoubtedly increase the volume of the movable part 121. When integrated in an area with limited space such as the wheel cavity 11, this increase in volume will increase the difficulty of integrating the movable part 121 on the vehicle. Therefore, in some specific implementation schemes, the number of support portions 122a can be, for example, 2 to 4. More specifically, the number of support portions 122a is, for example, two, so that the movable part 121 can be easily integrated and used in the vehicle wheel cavity 11 while being stably installed in the vehicle wheel cavity 11 by using the support member 122.
[0115] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 As shown, the movable member 121 is provided with a connecting groove 121c. The connecting groove 121c penetrates the movable member 121. The flow guide member 110 and the guide member are rotatably connected around the second rotation axis L2 so that the flow guide member 110 has at least a first movable position relative to the movable member 121; when the flow guide member 110 is in the first movable position, the flow guide member 110 and the surface of the movable member 121 are in contact with each other to close the connecting groove 121c.
[0116] Like this, by providing the connecting groove 121c, the airflow can pass through the movable part 121 at the connecting groove 121c, and the airflow can flow from one side of the movable part 121 to the other side. Specifically, when the movable part 121 is integrated into a vehicle for use, the airflow can flow from the bottom of the movable part 121 to the top of the movable part 121, which is beneficial to use the airflow to cool and dissipate the components on the vehicle located above the movable part 121. When the guide member 110 is in the first active position, the connecting groove 121c is closed, and the airflow no longer flows to the components on the vehicle located above the movable part 121. When the vehicle passes through a bad road section with mud, gravel, etc., this setting is beneficial to provide protection for the components above the movable part 121.
[0117] In some embodiments, reference Figure 4 As shown, the guide member 110 also has a second active position relative to the movable member 121; when the guide member 110 is in the second active position, at least a portion of the guide member is separated from the surface of the movable member 121 to open the connecting groove 121c, so as to utilize the airflow passing through the connecting groove 121c to dissipate heat from the vehicle components.
[0118] In some embodiments, reference Figure 2 and Figure 6 As shown, the vehicle-mounted flow guide device 100 also includes: a flow guide groove body 140. The flow guide groove body 140 is arranged on the first side A1 of the movable part 121 and is formed with a flow guide groove 140a connected to the connecting groove 121c. When the flow guide member 110 is in the second active position, the connecting groove 121c is opened so that the flow guide groove 140a is connected to the second side A2 of the movable part 121 opposite to the first side A1 through the connecting groove 121c. The flow guide groove body 140 is protrudingly arranged on the first side A1 of the movable part 121. In a specific solution, when the vehicle-mounted flow guide device 100 is integrated on the vehicle, the first side A1 of the movable part 121 is relatively above the second side A2. Like this, by setting the drainage groove body 140 on the first side A1 of the movable part 121, when the airflow flows from the second side A2 along the connecting groove 121c to the first side A1, the airflow is guided by the drainage groove 140a to flow to other parts of the vehicle. For example, by adjusting the extension direction of the drainage groove 140a, the drainage groove body 140 is made close to the brake disc 14 of the vehicle, so that the airflow is used to dissipate the heat of the brake disc 14, which is beneficial to the stable operation of the parts on the vehicle.
[0119] In some embodiments, the rotary drive member 130 is disposed on the first side A1 of the movable member 121 so as to provide protection for the rotary drive member 130 by the movable member 121 when the vehicle passes through a bad road section.
[0120] In some embodiments, reference Figure 5 As shown, the deflector 110 includes: a contact portion 111 and an embedding portion 112. The contact portion 111 is in contact with the surface of the movable member 121 when the deflector 110 is in the first active position, so as to reduce the occupation of the space below the movable member 121 by the whole formed by the movable member 121 and the deflector 110, and reduce the vehicle resistance increased by the installation of the deflector 110. The embedding portion 112 is protrudingly arranged on the surface of the contact portion 111, and when the deflector 110 is in the first active position, the embedding portion 112 is at least partially embedded in the connecting groove 121c to close the connecting groove 121c. The installation of the embedding portion 112 is also conducive to increasing the thickness of the deflector 110 and ensuring its structural strength.
[0121] In some embodiments, the vehicle-mounted air guide device 100 further includes: a flip drive motor 150. The flip drive motor 150 is connected to the air guide 110 to drive the air guide 110 to rotate relative to the movable part 121 around the second rotation axis L2. In a specific solution, the second rotation axis L2 is located at the end of the air guide 110. When the air guide 110 is in the second active position, one end of the air guide 110 close to the second rotation axis L2 is rotationally connected to the movable part 121, so that when the air guide 110 is in the second active position, it can flip to the second side A2 of the movable part 121 and be inclined or perpendicular to the surface of the movable part 121 to guide the airflow direction and block the airflow to increase the wind resistance of the vehicle. In a more specific solution, the second rotation axis L2 is perpendicular to the first rotation axis L1.
[0122] According to the second aspect of the present application, referring to Figures 7 to 13 As shown, a vehicle 10 is provided, comprising the above-mentioned vehicle-mounted flow guiding device 100. The vehicle 10 has all the beneficial effects of the above-mentioned vehicle-mounted flow guiding device 100, and the present application will not repeat them here.
[0123] The vehicle 10 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this application does not make any specific limitation on this.
[0124] In some embodiments, reference Figure 8 As shown, the vehicle 10 has a first driving mode; wherein, when the vehicle 10 is in the first driving mode, the adjustment component 120 is in a first adjustment position relative to the chassis 12 of the vehicle. Specifically, the first adjustment position is, for example, the initial position of the adjustment component 120 relative to the chassis 12. It can be further defined that when the steering wheel of the vehicle is aligned so that the forward direction of the wheel 13 is the same as the direction of the vehicle body, the adjustment component 120 is in the first adjustment position. When the vehicle 10 is in the first driving mode, the air guide 110 is in a first active position relative to the adjustment component 120, so that the air guide 110 prevents the airflow from flowing from the bottom of the chassis 12 to the top of the chassis 12. This form mode is applied, for example, when the vehicle is driving in a straight line or turning with a small amplitude (for example, the steering angle of the wheel 13 does not exceed 5°), by limiting the position of the air guide 110, the airflow passes from the bottom of the active part 121. At this time, the wind resistance of the vehicle 10 is low when driving, so as to reduce the energy consumed by the vehicle 10 to maintain driving, that is, it can achieve a driving state with low wind resistance and low energy consumption.
[0125] In some embodiments, reference Figures 9 and 10As shown, the vehicle 10 has a second driving mode; wherein, when the vehicle 10 is in the second driving mode, the adjustment component 120 is in the second adjustment position relative to the chassis 12 of the vehicle, so that the adjustment component 120 avoids the wheel 13 of the vehicle when the vehicle 10 turns. Specifically, when the vehicle turns, as the steering wheel turns or the wheel 13 swings, the adjustment component 120 adaptively moves to the second adjustment position so that the adjustment component 120 does not interfere with the position of the wheel 13 or other parts on the vehicle. When the vehicle 10 is in the second driving mode, the deflector 110 is in the first active position relative to the adjustment component 120. In this mode, the adjustment component can be prevented from interfering with the normal steering of the wheel when the vehicle turns, and objects such as mud and gravel on the road surface can be prevented from causing damage to the vehicle's parts.
[0126] In some embodiments, the angle at which the adjustment component 120 rotates around the first rotation axis L1 in the second adjustment position relative to the first adjustment position is equal to the turning direction angle of the vehicle. That is, during the vehicle turning process, the position of the adjustment component 120 is adaptively adjusted accordingly to avoid the adjustment component 120 interfering with the normal movement of the wheel 13 or other components.
[0127] In some embodiments, reference Fig.11 As shown, the vehicle 10 has a third driving mode, wherein when the vehicle 10 is in the third driving mode, the air guide 110 is in the second active position relative to the adjustment assembly 120, so that the air guide obstructs the airflow passing through the underside of the vehicle chassis and guides the airflow to dissipate heat to the vehicle's brake system. In this mode, the air guide 110 can be used to obstruct the airflow passing through the wheel cavity 11, thereby increasing the resistance encountered by the vehicle when driving. Therefore, it can be used to provide additional resistance to the vehicle 10 when the vehicle 10 is in emergency braking or other driving conditions when driving at high speed. In addition, based on the cooperation between the connecting groove 121c and the air guide 110, the airflow passing through the connecting groove 121c can also be used for heat dissipation of the vehicle. For example, the brake disc 14 of the vehicle's brake system is cooled.
[0128] In some embodiments, at least two vehicle-mounted flow guide devices 100 are spaced apart on the vehicle 10 along the width direction of the vehicle 10. By integrating more vehicle-mounted flow guide devices 100 on the vehicle 10, these flow guide devices can be used to flexibly adjust the resistance encountered by both sides of the vehicle when traveling. For example, in usage scenarios such as vehicle turning, this configuration can assist the vehicle to complete the turning action more quickly.
[0129] As an exemplary illustration of a specific solution, refer to Figures 8 to 13 As shown, in some embodiments, the plurality of vehicle-mounted flow guiding devices 100 include: a first flow guiding device 100a and a second flow guiding device 100b; accordingly, referring to Fig.12As shown, the vehicle has a fourth driving mode; wherein, when the vehicle is in the fourth driving mode, the deflector 110 of the first deflector device 100a is in the first active position, and the deflector 110 of the second deflector device 100b is in the second active position, so that the wind resistance on the left side of the vehicle body is greater than the wind resistance on the right side. In this way, when the vehicle turns left, the resistance on the left side of the vehicle can be increased to assist in completing the left turning action of the vehicle.
[0130] In some embodiments, reference Fig.13 As shown, the vehicle 10 has a fifth driving mode; wherein, when the vehicle 10 is in the fifth driving mode, the deflector 110 of the first deflector 100a is in the second active position, and the deflector 110 of the second deflector 100b is in the first active position, so that the wind resistance on the right side of the vehicle body is greater than the wind resistance on the left side. In this way, when the vehicle 10 turns right, the resistance on the right side of the vehicle 10 can be increased to assist in completing the right turning action of the vehicle.
[0131] When the vehicle 10 turns left or right, the guide members 110 of the first guide device 100a and the second guide device 100b do not necessarily need to be in the second active position. For example, when turning at a relatively low speed, or when turning in adverse road conditions such as mud or gravel, the guide members 110 of the first guide device 100a and the second guide device 100b can also be controlled to be in the first position.
[0132] In some embodiments, when the vehicle 10 is in the fourth driving mode or the fifth driving mode, the adjustment component 120 is in the second adjustment position. That is, when the vehicle 10 turns, the adjustment component 120 adjusts its position as the wheel 13 or the steering wheel rotates, and the real-time position of the adjustment component 120 matches the real-time position of the wheel 13, so as to avoid the adjustment position hindering the normal realization of the turning action.
[0133] According to the third aspect of the present application, referring to Fig.14 As shown, a vehicle wind resistance adjustment method is provided, which is implemented by the above-mentioned vehicle-mounted flow guide device 100 or by the above-mentioned vehicle. Specifically, the vehicle wind resistance adjustment method includes:
[0134] S100, adjusting the relative position between the vehicle-mounted flow guiding device 100 and the wheel 13 according to the vehicle driving parameters.
[0135] Like this, when the vehicle is in emergency braking at high speed, passing through muddy, gravel and other harsh roads, turning, rapid heat dissipation of components and other different usage conditions, the real-time position of the vehicle-mounted air flow guide device 100 is adjusted to guide the flow direction of the airflow, adapt to the different usage conditions of the vehicle, meet the different usage needs of the vehicle, and enhance the user's driving experience.
[0136] In some embodiments, step S100 includes:
[0137] S110, when the vehicle driving parameter meets the first preset condition, the air guide member 110 is controlled to be in the first active position relative to the vehicle chassis 12, otherwise, the air guide member 110 is controlled to be in the second active position relative to the vehicle chassis 12;
[0138] The angles between the air guide 110 and the adjustment assembly 120 are different when the air guide 110 is in the first active position and the second active position. In this way, by controlling the position of the air guide 110, when the vehicle needs to brake, turn, dissipate heat, accelerate, etc., the position of the air guide 110 can be flexibly adjusted to use the airflow guided by the air guide 110 to adjust the wind resistance received by the vehicle when driving, dissipate heat for components on the vehicle, and other functions.
[0139] In some embodiments, step S100 further includes:
[0140] S120, when the vehicle driving parameter meets the second preset condition, the control adjustment component 120 is in the first adjustment position relative to the vehicle chassis 12, otherwise the control adjustment component 120 is in the second adjustment position relative to the vehicle chassis 12;
[0141] When the adjustment assembly 120 is in the first adjustment position and in the second adjustment position, the relative positions between the air guide 110 and the vehicle wheel 13 are set differently.
[0142] With such arrangement, when the vehicle is moving straight or turning, the position of the adjusting component 120 is controlled so as to adapt to the cooperation with the wheel 13 and other components of the vehicle, so that the positions of the adjusting component 120 and the guide member 110 do not interfere with the positions of other components on the vehicle, thereby allowing the vehicle to normally complete actions such as turning and moving straight.
[0143] It can be seen from the functions implemented by the above steps S110 and S120 that in the present application, the guide member 110 can be adjusted according to the vehicle driving parameters, and the vehicle driving parameters include at least one of the vehicle's travel speed, road condition information, vehicle braking status, braking system temperature, and the steering angle of the wheel 13.
[0144] The vehicle's traveling speed is collected by, for example, a speed sensor integrated on the vehicle.
[0145] The vehicle braking state is provided by the braking system, for example, by detecting whether the vehicle brake pedal is stepped on, or detecting the braking force during braking, etc., through a pressure sensor, a displacement sensor, etc. Therefore, the first preset condition, for example, includes that the vehicle speed is less than the vehicle speed threshold and the brake is not stepped on. When the first preset condition is not met, that is, when the vehicle is traveling at a speed higher than the preset threshold and braking, the wind resistance of the vehicle during braking is increased by adjusting the position of the guide member 110, which is beneficial for achieving rapid braking and deceleration of the vehicle when the vehicle is traveling at a higher speed.
[0146] The road condition information is collected by, for example, cameras and temperature sensors on the vehicle. For ease of description, these devices for collecting road condition information are referred to as "environmental sensors" hereinafter. More specifically, the road condition information includes, for example, the ambient temperature of the vehicle, and whether there are objects such as mud and gravel on the road surface. Therefore, the first preset condition includes, for example, bad road conditions such as mud and gravel, that is, when the road conditions are bad, the position of the guide member 110 is adjusted so that the mud and gravel will not splash and damage the components above the adjustment assembly 120.
[0147] The temperature of the brake system is, for example, detected and acquired by a temperature sensor integrated in the vehicle brake system. Accordingly, the first preset condition includes, for example, that the temperature of the brake system does not exceed a temperature threshold. When the temperature of the brake system exceeds the threshold, the air flow is guided to flow to the components of the brake system, for example, to the brake disc installed on the wheel 13, by adjusting the guide member 110 to be in the second position, so as to cool the components of the brake system.
[0148] The steering angle of the wheel 13 is detected by, for example, an angle sensor integrated in the vehicle that detects the steering wheel turning angle. Accordingly, the second preset condition includes, for example, that the angle of the vehicle steering wheel turning relative to straight driving does not exceed a preset value. In this way, when the vehicle turns, the adjustment component 120 can be controlled to rotate so that the adjustment component 120 does not interfere with the normal steering of the wheel 13.
[0149] In some embodiments, the vehicle driving parameters collected by the above-mentioned sensors and other devices can be transmitted to the vehicle controller in the form of electrical signals, and the vehicle controller can be used to process the vehicle driving parameters and control the position of the adjustment component 120 or the guide member 110 at the wheel cavity 11 of the vehicle chassis 12 according to the vehicle driving parameters. Of course, the vehicle driving parameters can also be processed by other devices on the vehicle and used as a reference for controlling the position of the adjustment component 120 and the guide member 110, and this application does not limit this.
[0150] In some embodiments, the vehicle wind resistance adjustment method further includes:
[0151] S200. When the deviation between the current position of the guide member 110 relative to the vehicle chassis 12 and the preset active position meets a third preset condition, the control adjustment component 120 and / or the guide member 110 is maintained at the current position; otherwise, the control guide member 110 and / or the guide member 110 is moved to the preset active position relative to the vehicle chassis 12.
[0152] As a specific solution, the guide member 110 is rotatably connected with the adjustment assembly 120 around the second rotation axis L2; the second rotation axis L2 is inclined or perpendicular to the first rotation axis L1;
[0153] The third precondition includes:
[0154] The difference between the angle of the guide member 110 rotated around the second rotation axis L2 in the current position relative to the first active position and the preset rotation angle is less than or equal to the first threshold.
[0155] Like this, after the guide member 110 is flipped relative to the adjustment assembly 120, the flipping angle of the guide member 110 can be adjusted in time when the flipping angle deviation of the guide member 110 is too large by comparing the difference between the actual flipping angle of the guide member 110 and the preset rotation angle with the first threshold, so as to more accurately control the wind resistance encountered by the vehicle when driving.
[0156] In some embodiments, the vehicle wind resistance adjustment method further includes:
[0157] When the deviation between the current position of the adjustment component 120 relative to the vehicle chassis 12 and the preset adjustment position meets the fourth preset condition, the adjustment component 120 is controlled to remain in the current position, otherwise the adjustment component 120 is controlled to move to the preset adjustment position relative to the vehicle chassis 12 .
[0158] As a specific solution, the fourth precondition includes:
[0159] The difference between the angle of the adjustment component 120 rotated around the first rotation axis L1 in the current position relative to the first active position and the steering angle of the wheel 13 is less than or equal to the second threshold.
[0160] Like this, by comparing the difference between the rotation angle of the adjusting component 120 and the steering angle of the wheel 13 and the second threshold, when the rotation angle deviation of the adjusting component 120 is too large, the position of the adjusting component 120 is adjusted in time so that it does not interfere with the wheel 13 and other components in space.
[0161] Based on the above-mentioned vehicle wind resistance adjustment method, when a vehicle is used to implement the method, the vehicle can at least realize the above-mentioned first driving mode, second driving mode, third driving mode, fourth driving mode and fifth driving mode.
[0162] Specifically, when the vehicle speed is greater than a first threshold speed, the angle through which the steering wheel is turned when driving relatively straight (i.e., the vehicle turning direction angle mentioned above) is less than a preset rotation threshold, the brake does not perform a braking action, the environmental sensor detects that the vehicle is not driving in adverse road conditions such as mud, and the brake disc temperature is less than or equal to a preset temperature, the on-board controller can be used to control the on-board diversion device to be in the first driving mode, so as to enable the vehicle to travel along a path that is close to a straight line with lower wind resistance.
[0163] When environmental sensors detect that the vehicle is traveling in bad road conditions such as mud, the on-board controller can be used to control the on-board guide device to be in the second driving mode, so that the guide parts above the adjustment assembly can be prevented from being damaged under bad road conditions, so that the vehicle can operate stably.
[0164] When the braking force is greater than a preset braking force threshold and the brake disc temperature is greater than a preset temperature threshold, the on-board controller can be used to control the on-board flow guide device to be in the third driving mode, so as to increase the wind resistance of the vehicle during driving by using the movement of the flow guide, and to use the airflow to dissipate heat from the vehicle's brake disc 14. At this time, the adjustment component can be further controlled to be in the second adjustment position so that the adjustment component avoids the wheel when the vehicle turns.
[0165] It is also possible to control the on-board flow guide device to be in the fourth driving mode by using the on-board controller when the vehicle speed is greater than the second threshold speed, the steering wheel turns left and the angle turned relatively straight is greater than the preset turning threshold, and the brake does not perform a braking action, so that the vehicle can stably complete the left turn at a higher driving speed. The second threshold speed may be greater than or equal to the first threshold speed, that is, the vehicle is in the fourth driving mode only when the vehicle speed is relatively high, and at a lower driving speed, the activity of the flow guide may not be used to increase the wind resistance of the vehicle during driving.
[0166] It is also possible to use the on-board controller to control the on-board flow diversion device to be in the fifth driving mode when the vehicle's driving speed is greater than the second threshold speed, the steering wheel turns right and the angle turned relatively straight is greater than the preset rotation threshold, and the brakes do not perform braking action, so as to enable the vehicle to stably complete the right turn at a higher driving speed.
[0167] It should be noted that the specific values of the aforementioned first threshold speed, second threshold speed, preset rotation threshold, preset braking force threshold, preset temperature threshold, etc. can be flexibly configured according to usage requirements, and this application does not impose any restrictions on this.
[0168] For the purpose of specifically explaining the inventive concept of the present application, a specific implementation scheme of the above-mentioned vehicle wind resistance adjustment method when it acts on a vehicle is provided below. In this scheme, the above-mentioned first deflector 100a and second deflector 100b are provided on the vehicle 10, wherein the first deflector 100a is provided at the wheel cavity where the right front wheel of the vehicle is installed, and the second deflector 100b is provided at the wheel cavity where the left front wheel of the vehicle is installed. It should be understood that this specific implementation scheme should be regarded as an exemplary description of the specific implementation scheme of the present application, and not the only limitation to the specific implementation scheme of the present application. In the following, α1 is defined as the angle that the deflector 110 of the first deflector 100a rotates around the second rotation axis L2 relative to when it is in the first active position, and α2 is defined as the angle that the deflector 110 of the second deflector 100b rotates around the second rotation axis L2 relative to when it is in the first active position. β is defined as the angle through which the movable member 121 of the first flow guiding device 100a and the second flow guiding device 100b rotates around the first rotation axis L1 when the movable member 121 is in the first adjustment position relative to the adjustment assembly 120.
[0169] In the initial stage of executing the vehicle wind resistance adjustment method, the vehicle is initialized, that is, the air guide 110 is in the first active position and the adjustment assembly 120 is in the first adjustment position.
[0170] In order to achieve flexible adjustment of the wind resistance experienced by the vehicle 10 during driving, the sensors and other devices integrated on the vehicle as mentioned above can be used to obtain the vehicle's current driving speed v, the angle θ that the steering wheel turns relative to straight driving (wherein the angle turned when the vehicle turns left is defined as a negative value, and the angle turned when the vehicle turns right is defined as a positive value), the temperature T of the braking system (in a more specific solution, the temperature T of the braking system is, for example, the temperature of the brake disc), the braking force B, and the road condition information E.
[0171] When V>V1, |θ|<θ1, B=False, E=Normal, the vehicle is controlled to be in the low wind resistance mode, so that the guide member 110 of the first guide device 100a and the second guide device 100b is in the first active position (the position of the guide member 110 around the second rotation axis L2 is defined as the position where the rotation angle α of the guide member 110 is 0), and the adjustment assembly 120 of the first guide device 100a and the second guide device 100b is in the first adjustment position (the position of the movable member 121 around the first rotation axis L1 is defined as the position where the rotation angle β of the movable member 121 is 0). Among them, V1 is the above-mentioned first threshold speed, θ1 is the above-mentioned preset angle threshold, B=False is defined as the vehicle is not braking, and E=Normal is defined as the environmental sensor detects that the current road condition is not a bad road condition such as muddy, gravel, etc.
[0172] When V>V2, |θ|>θ1, B=False, E=Normal, and θ is a negative value, the vehicle is controlled to be in the high-speed left turn mode, so that the guide member 110 of the first guide device 100a is in the first active position, and the guide member 110 of the second guide device 100b is in the second active position (the angle of rotation of the guide member 110 relative to the first active position around the second rotation axis is defined as α max ), and the adjustment components 120 of the first guide device 100a and the second guide device 100b are in the second adjustment position (ie, controlling β=θ), wherein V2 is the second threshold speed mentioned above.
[0173] When V>V2, |θ|>θ1, B=False, E=Normal, and θ is a positive value, the vehicle is controlled to be in high-speed right turn mode, so that the guide member 110 of the first guide device 100a is in the second active position, the guide member 110 of the second guide device 100b is in the first active position, and the adjustment assembly 120 of the first guide device 100a and the second guide device 100b is in the second adjustment position.
[0174] When V>V3, B=True and B>B1, E=Normal, the vehicle is controlled to be in high-speed braking mode, so that the guide members 110 of the first guide device 100a and the second guide device 100b are in the second active position, and the adjustment components 120 of the first guide device 100a and the second guide device 100b are in the second adjustment position. Among them, B=True is defined as the vehicle is braking, and B>B1 is defined as the braking force provided by the brake disc to the wheel is greater than the preset value, and B1 is the above-mentioned preset braking force threshold. Among them, V3 is the third threshold speed, which is defined as being used to determine whether the speed of the vehicle before braking is relatively high. Based on its definition, the third threshold speed can be configured to be greater than the second threshold speed, that is, V3>V2.
[0175] When T>T1, the vehicle is controlled to be in the brake cooling mode, so that the guide members 110 of the first guide device 100a and the second guide device 100b are in the second active position. It can be understood that T1 is the above-mentioned preset temperature threshold.
[0176] When E=harsh, the vehicle is controlled to be in a harsh road driving mode, so that the guide members 110 of the first guide device 100a and the second guide device 100b are in the first active position. E=harsh is defined as the environmental sensor detecting that the vehicle is currently driving on a harsh road section. At this time, the adjustment components 120 of the first guide device 100a and the second guide device 100b can be in the first adjustment position or the second adjustment position as needed.
[0177] It can be understood that the low wind resistance mode is the above-mentioned first driving mode, the severe road condition driving mode is the above-mentioned second driving mode, the high-speed braking mode and the brake cooling mode can be considered as specific implementation plans of the above-mentioned third driving mode, the high-speed left turn mode is the above-mentioned fourth driving mode, and the high-speed right turn mode is the above-mentioned fifth driving mode.
[0178] Of course, the above content only describes part of the vehicle's driving mode. According to actual conditions, more preset conditions can be configured, and when the corresponding preset conditions are met, the positions of the movable parts 121 and the guide parts 110 of the first guide device 100a and the second guide device 100b are controlled to enrich the adjustment scheme for the vehicle's driving resistance.
