[0098] 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.

[0099] According to the first aspect of the present application, referring to Figure 1 and Figure 2 The present application provides a vehicle spoiler device 100 , including a spoiler body 110 , a cover 120 and a driving mechanism 130 .

[0100] The spoiler body 110 is surrounded by a hollow area 100a for airflow to pass through; the cover 120 is installed on the spoiler body 110; the driving mechanism 130 is configured to at least drive the cover 120 to move from the spoiler body 110 to the hollow area 100a, so that the cover 120 can cover at least part of the hollow area 100a.

[0101] It can be understood that the hollow area 100a is a channel for airflow to pass through, which may be surrounded by the spoiler body 110 alone, or may be surrounded by the spoiler body 110 and the roof 21 of the vehicle 1, the rear windshield 22, etc.

[0102] The driving component drives the cover 120 to move from the spoiler body 110 to the hollow area 100a, which can actively change the position of the cover 120, or actively change the shape of the cover 120, or change the position or shape of the cover 120 at the same time.

[0103] Through the above technical solution, the driving component drives the cover 120 to move from the spoiler body 110 to the hollow area 100a, so that the cover 120 can cover at least a portion of the hollow area 100a, thereby changing the shape of the whole formed by the spoiler body 110 and the cover 120, adjusting the airflow distribution and flow direction near the spoiler body 110, and realizing active noise reduction. It can fundamentally eliminate the howling and broadband wind noise of the spoiler body 110 when driving at high speed, adapt to different states of the vehicle 1, and improve the noise comfort of the passengers in the vehicle.

[0104] In some specific embodiments, the spoiler body 110 can be fixedly connected to the roof 21 of the vehicle 1 and at least partially located above the rear windshield 22; both sides of the spoiler body 110 can be located between two D-pillars 23 of the vehicle 1. With such an arrangement, the downward flow of rainwater from the roof 21 will not be affected.

[0105] In some specific embodiments, the cover 120 in the present application is moved from the spoiler body 110 to the hollow area 100a. It is understood that the cover 120 can be arranged on the upper surface, lower surface or inside of the spoiler body 110, so that when the cover 120 is not extended from the spoiler body 110, the cover 120 is hidden in the area where the spoiler body 110 is located, taking into account the aesthetics of the shape, and the cover 120 will not block the rear windshield 22 of the vehicle 1 and affect the line of sight.

[0106] In some embodiments, reference Figures 1 to 5 The spoiler body 110 is provided with a receiving space 110a, and at least a portion of the cover 120 is disposed in the receiving space 110a. By disposing at least a portion of the cover 120 in the receiving space 110a, the interference of the cover 120 on the airflow is reduced, and the cover 120 is prevented from affecting the aesthetic appearance of the spoiler.

[0107] In some embodiments, reference Figures 1 to 5 At least part of the driving mechanism 130 is disposed in the accommodation space 110a. By disposing at least part of the driving mechanism 130 in the accommodation space 110a, the interference of the driving mechanism 130 on the airflow is reduced, and the driving mechanism 130 is prevented from affecting the aesthetic appearance of the spoiler.

[0108] In some embodiments, reference Figures 1 to 5 The spoiler body 110 includes a first guide portion 111 and a second guide portion 112 that are arranged opposite to each other; wherein the accommodating space 110 a is formed between the first guide portion 111 and the second guide portion 112 .

[0109] Specifically, the first guide portion 111 is located on the side of the spoiler body 110 facing the rear windshield 22, and is used to guide the airflow flowing through the spoiler body 110 and the rear windshield 22; the second guide portion 112 is located on the side of the spoiler body 110 away from the rear windshield 22, and is used to guide the airflow flowing through the upper surface of the spoiler body 110.

[0110] It can be understood that the accommodation space 110a is an interlayer space formed inside the spoiler body 110, and an opening communicating with the accommodation space 110a is formed on the front side of the spoiler body 110, so that the cover 120 can extend from the opening.

[0111] In some embodiments, reference Figures 1 to 5 The driving mechanism 130 includes a prime mover 131. The prime mover 131 is used to provide power for the movement of the cover 120, so that the cover 120 has at least a first state and a second state relative to the spoiler body 110.

[0112] Among them, refer to Figures 8 to 11 , when the cover 120 is in the first state, the cover 120 covers at least a portion of the hollow area 100a; Figure 6 and Figure 7 When the cover 120 is in the second state, the cover 120 is stored in the spoiler body 110 .

[0113] It can be understood that when the cover 120 is in the first state, the cover 120 extends from the spoiler body 110, and it can extend from the back to the front, or from the left and right sides to the middle, so that the hollow area 100a is in a partially closed or fully closed state. When the cover 120 is in the second state, the cover 120 retreats to the spoiler body 110, so that the hollow area 100a is in a fully open state.

[0114] By adopting such a solution, the cover 120 is switched to different states so that the whole formed by the cover 120 and the spoiler body 110 has different shapes, and the airflow distribution and flow direction near the spoiler body 110 are adjusted to achieve active noise reduction.

[0115] In some embodiments, the prime mover 131 includes one of a gas rod, an electric push rod, and an electric cylinder.

[0116] In some specific embodiments, the prime mover 131 may be a gas rod, which is connected to a gas source, such as an air pump, through a pipeline to achieve extension and retraction of the gas rod.

[0117] In some embodiments, reference Figure 1 to Figure 2The driving mechanism 130 further includes a transmission assembly 130a. The transmission assembly 130a is coupled with the prime mover 131 and the cover 120 to enable the cover 120 to switch between the first state and the second state.

[0118] By adopting such a solution, power transmission is achieved between the prime mover 131 and the cover 120 through the transmission component 130a. On the premise of meeting the movement requirements of the cover 120, the linear size of the prime mover 131 is reduced, and it is beneficial to the spatial arrangement of the prime mover 131, the cover 120, etc.

[0119] In some specific embodiments, the transmission assembly 130a may be a crank rocker mechanism, a gear rack mechanism, etc., which may be a mechanism that converts the power of the prime mover 131 into a linear driving force.

[0120] In some embodiments, reference Figures 1 to 3 The transmission assembly 130a includes: a first connecting rod 132 and a second connecting rod 133.

[0121] The first connecting rod 132 is rotationally connected to the cover 120; the second connecting rod 133 and the first connecting rod 132 form a transmission coupling; wherein the second connecting rod 133 is configured to rotate under the drive of the prime mover 131 to drive the first connecting rod 132 to act on the cover 120 in a preset motion posture.

[0122] Specifically, the first connecting rod 132 and the cover 120 , the second connecting rod 133 and the first connecting rod 132 , and the prime mover 131 and the first connecting rod 132 are connected via connecting pins, respectively.

[0123] Exemplarily, when the prime mover 131 is extended, it drives the second link 133 to rotate forward, and the second link 133 drives the first link 132, so that the whole formed by the first link 132 and the second link 133 is unfolded, and the first link 132 pushes the cover 120 to slide along the spoiler body 110, thereby increasing the degree of shielding of the hollow area 100a, making it completely or partially closed.

[0124] When the prime mover 131 is shortened, it drives the second connecting rod 133 to rotate in the opposite direction, and the second connecting rod 133 drives the first connecting rod 132, so that the whole formed by the first connecting rod 132 and the second connecting rod 133 is folded, and the first connecting rod 132 pulls the covering member 120 to slide along the spoiler body 110, thereby reducing the degree of shielding of the hollow area 100a, or allowing the covering member 120 to be stored in the spoiler body 110.

[0125] By adopting such a solution, power is transmitted through the first connecting rod 132 and the second connecting rod 133, so that the smaller telescopic length of the prime mover 131 can control the larger movement stroke of the cover 120, reduce the size requirement of the prime mover 131, and facilitate the spatial arrangement of the prime mover 131.

[0126] In some embodiments, reference Figures 1 to 5 One end of the second connecting rod 133 is rotatably connected to the spoiler body 110 through the first support 134, and the first support 134 is located in the accommodating space 110a.

[0127] Exemplarily, the first support 134 is fixedly connected to the first air guide portion 111 , and one end of the second connecting rod 133 is hinged to the first support 134 , so as to ensure that the second connecting rod 133 can swing freely.

[0128] In some embodiments, one end of the prime mover is rotatably connected to the spoiler body 110 via a second support 135, and the second support 135 is located in the accommodating space 110a.

[0129] Exemplarily, the second support 135 is fixedly connected to the first air guide portion 111 , and one end of the prime mover is hinged to the second support 135 , so as to ensure that the prime mover 131 can swing freely.

[0130] In other embodiments, the prime mover 131 may also directly act on the cover 120 to push the cover 120 to move.

[0131] In some embodiments, reference Figures 1 to 5 The covering member 120 includes a flexible body 121 and a retaining body 122 .

[0132] The flexible body 121 is configured to be retractable in the spoiler body 110 in a structurally deformable manner; the retaining body 122 is connected to one end of the flexible body 121 to maintain the flexible body 121 extending out of the spoiler body 110 ; the driving mechanism 130 is connected to the retaining body 122 to apply force to the retaining body 122 .

[0133] It can be understood that the rigidity of the retaining body 122 is greater than that of the flexible body 121 , so that the retaining body 122 can support the flexible body 121 , and when the flexible body 121 is completely received in the accommodating space 110 a , the retaining body 122 can block the opening.

[0134] With such a solution, the volume requirement of the accommodation space 110a is reduced by setting the flexible body 121, and the storage of the cover 120 is facilitated. At the same time, the holding body 122 is combined with the flexible body 121, so that the holding body 122 can open the flexible body 121, so that the flexible body 121 remains taut in the left and right directions of the vehicle 1, reducing the impact on the airflow flowing through the surface of the flexible body 121.

[0135] In some specific implementations, the flexible body 121 may be a tarpaulin; the flexible body 121 may be stored in the spoiler body 110 in a folded or rolled manner.

[0136] In some embodiments, reference Figures 1 to 3 The spoiler device further includes a reel 141 . The reel 141 is rotatably connected to the spoiler body 110 and is used to reel up the flexible body 121 .

[0137] Specifically, both ends of the reel 141 are rotatably connected to the spoiler body 110 through bearing seats 142, the bearing seats 142 are located in the accommodating space 110a and fixedly connected to the first guide portion 111. When the cover 120 switches from the first state to the second state, the reeling amount of the flexible body 121 on the reel 141 increases accordingly.

[0138] It is understood that the reel 141 is also connected to an elastic member, and the reel 141 applies a force opposite to the extension direction to the flexible member, so that the flexible body 121 remains taut in the extension direction. More specifically, the elastic member can be a coil spring, a spring spring, or the like.

[0139] In some other specific implementations, the cover 120 may be configured as a rigid structure, in which case the cover 120 and the spoiler body 110 form a sliding connection.

[0140] According to a second aspect of the present application, an adjustment system 10 is provided. The adjustment system 10 includes the above-mentioned vehicle spoiler 100 .

[0141] Reference Fig.12 The adjustment system 10 also includes: an operation detection device 210 and a controller 220.

[0142] The operation detection device 210 is used to detect the current operation information of the vehicle 1 ; the controller 220 is configured to control the driving mechanism 130 to drive the cover 120 to move according to the current operation information of the vehicle 1 , so as to adjust the overall shape of the vehicle spoiler 100 .

[0143] Specifically, the operation detection device 210 and the prime mover 131 (or the air source) are electrically connected to the controller 220 .

[0144] Exemplarily, in a low-speed scenario, the cover 120 is placed in the second state, and the original hollow area 100a of the spoiler body 110 is maintained; as the vehicle speed increases, the cover 120 is placed in the first state, and the hollow area 100a is adjusted to be partially closed or fully closed through the cover 120, thereby changing the overall shape of the vehicle spoiler 100, thereby affecting the direction of the airflow and achieving the purpose of noise reduction.

[0145] By adopting such a solution, the working state of the cover 120 is actively switched through the controller 220 while the spoiler body 110 maintains its original function, which has better flexibility and can adapt to different scenarios of the vehicle 1.

[0146] In some specific implementations, the controller 220 may be the vehicle 1 controller 220 or an independent controller 220 .

[0147] In some embodiments, the current operating information of the vehicle 1 includes at least one of the vehicle speed of the vehicle 1 , the sound pressure level inside the vehicle, and the current state of the cover 120 .

[0148] It can be understood that the vehicle speed refers to the distance traveled by the vehicle 1 in a unit time; the sound pressure level inside the vehicle indicates the strength of the noise inside the vehicle; the current state of the cover 120 refers to the current state of the cover 120, which can be the first state or the second state.

[0149] In some embodiments, reference Fig.12 The operation detection device 210 includes: a sound pressure collector 211. The sound pressure collector 211 is used to obtain the sound pressure level inside the vehicle 1; wherein the controller 220 is configured to control the operation of the driving mechanism 130 according to the sound pressure level inside the vehicle 1.

[0150] By adopting such a scheme, the operation of the driving mechanism 130 is controlled according to the sound pressure level inside the vehicle 1, so that the state of the cover 120 matches the sound pressure level inside the vehicle 1, thereby achieving adaptive adjustment of the overall shape of the spoiler and realizing active noise reduction.

[0151] In some specific implementations, the sound pressure collector 211 may be an acoustic microphone.

[0152] In some embodiments, reference Fig.12 The operation detection device 210 includes: a vehicle speed collector 212. The vehicle speed collector 212 is used to obtain the vehicle speed of the vehicle 1; wherein the controller 220 is configured to control the operation of the driving mechanism 130 according to the vehicle speed of the vehicle 1.

[0153] By adopting such a solution, the operation of the driving mechanism 130 is controlled according to the speed of the vehicle 1 so that the state of the cover 120 matches the speed of the vehicle 1, thereby achieving adaptive adjustment of the overall shape of the spoiler and realizing active noise reduction.

[0154] In some specific implementations, the vehicle speed collector 212 may be a vehicle speed sensor or an inertial measurement unit (IMU, Inertial Measurement Unit), etc.

[0155] In some embodiments, the controller 220 is configured to control the operation of the driving mechanism 130 according to the sound pressure level inside the vehicle 1 and the vehicle speed of the vehicle 1 .

[0156] It can be understood that the drive mechanism 130 is controlled to operate in combination with the sound pressure level inside the vehicle 1 and the vehicle speed of the vehicle 1. The drive mechanism 130 can be controlled to operate when either of the two meets the preset condition, or when both meet the preset condition at the same time.

[0157] By adopting such a scheme, the driving mechanism 130 is controlled according to the sound pressure level inside the vehicle 1 and the speed of the vehicle 1, and the overall shape of the spoiler is adjusted to match the sound pressure level inside the vehicle 1 and the speed of the vehicle 1, thereby meeting the aerodynamic performance and realizing active noise reduction.

[0158] In some embodiments, reference Fig.12 The adjustment system 10 further includes a state detection device 230 . The state detection device 230 is used to detect the current state of the cover 120 ; wherein the controller 220 is further configured to control the action of the driving mechanism 130 according to the current state of the cover 120 .

[0159] It can be understood that the current state of the cover 120 may be in the first state, at which time the hollow area 100a is in a partially closed state or a fully closed state; when the hollow area 100a is in a partially closed state, the cover 120 can continue to move in the direction of closing the hollow area 100a or continuing to open the hollow area 100a; when the hollow area 100a is in a fully closed state, the cover 120 can only move in the direction of opening the hollow area 100a; the current state of the cover 120 may be in the second state, at which time the hollow area 100a is in a fully open state, and the cover 120 can only move in the direction of closing the hollow area 100a.

[0160] By adopting such a solution, the controller 220 can accurately control the action of the driving mechanism 130 by detecting the current state of the cover 120 .

[0161] In some specific implementations, the state detection device 230 can obtain the state of the covering member 120 by detecting the length of the covering member 120 extending out of the spoiler body 110 or by detecting the rotation angle of the reel 141 .

[0162] According to a third aspect of the present application, an adjustment method is provided, which is applied to the above-mentioned adjustment system, referring to Fig.13 The adjustment method includes the following main steps:

[0163] S110: Acquire current operation information of the vehicle;

[0164] S120: Controlling the cover to move to a target state according to current operating information of the vehicle to adjust the overall shape of the vehicle spoiler.

[0165] Exemplarily, in a low-speed scenario, the cover is placed in the second state, maintaining the original hollow area of ​​the spoiler body; as the vehicle speed increases, the cover is placed in the first state, and the hollow area is adjusted to be partially closed or fully closed through the cover, thereby changing the overall shape of the vehicle spoiler, thereby affecting the direction of the airflow and achieving the purpose of noise reduction.

[0166] By adopting such a solution, the state of the covering member is actively switched by the controller to adjust the overall shape of the vehicle spoiler, which is more flexible and can adapt to different vehicle scenarios.

[0167] In some embodiments, the current operating information of the vehicle includes at least one of the vehicle speed, the sound pressure level inside the vehicle, and the current state of the covering.

[0168] In some embodiments, step S120 includes the following specific steps:

[0169] When the current operating information of the vehicle meets the preset operating conditions, the cover is controlled to move to the target state.

[0170] Specifically, the preset operating condition includes at least one of: the sound pressure level inside the vehicle exceeds a preset sound pressure level threshold, and the vehicle speed exceeds a preset vehicle speed threshold.

[0171] Exemplarily, when the vehicle speed is greater than 110 km / h or the sound pressure level inside the vehicle is greater than 60 dBA, the control cover moves to the first state; when the vehicle speed is less than or equal to 110 km / h or the sound pressure level inside the vehicle is less than or equal to 60 dBA, the control cover moves to the second state.

[0172] By adopting such a solution, when the sound pressure level inside the vehicle and the vehicle speed meet the preset operating conditions, the cover is controlled to perform corresponding actions, thereby automatically controlling the overall shape of the spoiler. This can not only maintain the shape of the spoiler in the hollow area when the vehicle is driving at a low speed, but also reduce wind noise through the overall shape of the spoiler when the vehicle is driving at a high speed, and has strong flexibility.

[0173] In some embodiments, step S120 further includes the following specific steps:

[0174] When the duration of the current operation information of the vehicle satisfying the preset operation condition exceeds a preset time threshold, the cover is controlled to move to the target state.

[0175] Exemplarily, when the vehicle speed is greater than 110 km / h or the sound pressure level inside the vehicle is greater than 60 dBA and lasts for more than 2 minutes, the control cover moves to the first state; when the vehicle speed is less than or equal to 110 km / h or the sound pressure level inside the vehicle is less than or equal to 60 dBA and lasts for more than 2 minutes, the control cover moves to the second state.

[0176] By adopting such a solution, the judgment of duration is enhanced and the accuracy of cover control is improved.

[0177] In some embodiments, step S120 includes the following specific steps: controlling the driving mechanism to drive the cover to move according to the current state of the cover.

[0178] By adopting such a solution, the controller can accurately control the action of the driving mechanism by detecting the current state of the cover.

[0179] The above adjustment method realizes the adaptive control of the cover to meet the personalized needs of users. In some embodiments, the adjustment method further includes:

[0180] S200: Controlling the cover to move to a target state according to the user's operation instruction to adjust the overall shape of the vehicle spoiler.

[0181] It can be understood that the operation instructions can be obtained by the user through voice control, pad input, physical button input, etc.

[0182] By adopting such a solution, the movement of the cover can be controlled by the user inputting operation instructions, so that the state of the cover can be selected according to actual needs.

[0183] The following is an illustrative description of the adjustment method provided in the embodiments of the present application.

[0184] The control of the covering is divided into automatic control mode and manual control mode. Both modes can achieve the effect of switching the shape of the hollow spoiler.

[0185] The corresponding relationship between the state of the covering member and the overall state of the vehicle spoiler is specifically as follows: when the covering member is fully extended, the hollow area can be completely closed, and the vehicle spoiler is in a closed state; when the covering member is partially extended, it can partially block the hollow area, and the vehicle spoiler is in a half-open state; when the covering member is fully retracted, it will not block the hollow area, and the vehicle spoiler is in a fully open state.

[0186] Please refer to Fig.14 and Fig.15 , this application exemplarily provides specific steps in the automatic control mode:

[0187] Reference Fig.14 , obtain the vehicle speed and the sound pressure level inside the vehicle; when the vehicle speed is greater than 110km / h and lasts for more than 2min or the sound pressure level inside the vehicle is greater than 60dBA and lasts for more than 2min, continue to obtain the current state of the vehicle spoiler; when the current state of the vehicle spoiler is in the fully open state, control the vehicle spoiler to switch to the half-open state or the closed state, otherwise no operation is performed.

[0188] Reference Fig.15 , obtain the vehicle speed and the sound pressure level inside the vehicle; when the vehicle speed is less than or equal to 110km / h and lasts for more than 2min or the sound pressure level inside the vehicle is less than or equal to 60dBA and lasts for more than 2min, continue to obtain the current state of the vehicle spoiler; when the current state of the vehicle spoiler is in a half-open state or a closed state, control the vehicle spoiler to switch to a fully open state, otherwise no operation is performed.

[0189] Please refer to Fig.14 and Fig.15 , this application example provides specific steps in manual control mode:

[0190] Reference Fig.14 When the user's operation instruction is to close the vehicle spoiler, the current state of the vehicle spoiler is further obtained; when the current state of the vehicle spoiler is fully open, the cover is controlled to move to partially block or completely close the hollow area, otherwise the operation is not performed.

[0191] Reference Fig.15 When the user's operation instruction is to open the vehicle spoiler, the current state of the vehicle spoiler is further obtained; when the current state of the vehicle spoiler is in a half-open state or a closed state, the vehicle spoiler is controlled to switch to a fully open state, otherwise no operation is performed.

[0192] According to the third aspect of the present application, referring to Figure 1 , a vehicle 1 is provided, which includes the above-mentioned vehicle spoiler device 100, or the above-mentioned adjustment system 10, or is used to perform the above-mentioned adjustment method.
