Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically, to a vehicle body pressure relief valve adjustment device, method, and vehicle. Background Technology

[0002] The car's pressure relief valve is a "window" through which the passenger compartment connects to the outside air via the trunk. It mainly consists of a hollow valve body and multiple valve plates inside the valve body, with gaps between the valve plates. When the pressure inside the passenger compartment is too high (e.g., when the doors are closed, windows are closed while driving, or the air conditioning is on), the airflow inside the passenger compartment is released through the trunk and outwards from the gaps in the valve plates of the pressure relief valve to balance the pressure inside and outside the passenger compartment.

[0003] Currently, during vehicle operation, the airflow around the pressure relief valve easily generates wind noise in the gaps between the valve plates. To improve the wind noise problem at the pressure relief valve, a deflector structure with deflector holes is usually installed at the pressure relief valve to reduce wind noise while ensuring the exhaust function of the pressure relief valve. However, when the vehicle is traveling at high speed, the airflow velocity around the pressure relief valve also increases with the increase in vehicle speed, making it easy for the airflow to generate a loud and oppressive wind noise at the deflector holes, affecting the high-speed driving experience. Summary of the Invention

[0004] The problem solved by this invention is: how to reduce the loud, piercing wind noise at the vehicle's pressure relief valve when the vehicle is traveling at high speed, so as to improve the driving experience.

[0005] To address the aforementioned problems, the present invention provides a vehicle body pressure relief valve adjustment device, comprising a pressure relief valve, a spoiler mechanism, and an adjustment mechanism. The spoiler mechanism includes multiple spoilers and a support frame with multiple spoiler holes. The support frame is connected to the pressure relief valve. The multiple spoilers are arranged around the pressure relief valve and are respectively located at the corresponding spoiler holes. The adjustment mechanism is connected to the spoilers and is used to drive the spoilers to open or close the corresponding spoiler holes.

[0006] Optionally, the support frame includes multiple brackets, which are spaced apart around the valve body, and the gap between two adjacent brackets in the circumferential direction of the pressure relief valve forms the turbulence hole.

[0007] Optionally, the support frame further includes a connecting plate, with one end of each of the plurality of brackets connected to the pressure relief valve and the other end connected to the connecting plate.

[0008] Optionally, a first guide structure is provided on the inner wall of the turbulence hole, and a second guide structure is provided on the turbulence plate. The second guide structure is used to move relative to the first guide structure along an axial direction perpendicular to the turbulence hole.

[0009] Optionally, the adjusting mechanism comprises a tank body, a pump body and a connecting pipeline, the tank body is used for storing fluid medium, the spoiler plate has a cavity, one end of the connecting pipeline is connected with the tank body through the pump body, and the other end of the connecting pipeline is communicated with the cavities of the plurality of spoiler plates respectively;

[0010] When the pump body delivers the fluid medium to the cavities, the spoiler plates expand to block the spoiler holes, and when the pump body sucks the fluid medium from the cavities, the spoiler plates shrink to open the spoiler holes.

[0011] Optionally, the adjusting mechanism further comprises a control valve, the connecting pipeline comprises a main pipeline and a plurality of branch pipelines, one end of the main pipeline is connected with the tank body through the pump body, one end of each of the plurality of branch pipelines is communicated with the cavity of each of the plurality of spoiler plates, and the other end of each of the plurality of branch pipelines is communicated with the other end of the main pipeline through the control valve, and the control valve is used for controlling the on-off of the branch pipelines.

[0012] Compared with the prior art, the vehicle body pressure relief valve adjusting device has the following beneficial effects:

[0013] In the present application, the spoiler mechanism is arranged at the pressure relief valve, and the support frame of the spoiler mechanism is connected to the pressure relief valve to achieve the installation and fixation of the spoiler mechanism. Meanwhile, a plurality of spoiler plates of the spoiler mechanism are arranged at a plurality of spoiler holes of the support frame and around the pressure relief valve, so that when the spoiler plate closes the corresponding spoiler hole, the airflow on the side where the spoiler plate is located is blocked from entering the pressure relief valve, thereby reducing the wind noise generated at the pressure relief valve. Furthermore, the adjusting mechanism is arranged to drive the spoiler plate to open or close the corresponding spoiler hole. When the vehicle is running at a low speed, the airflow around the pressure relief valve flows slowly, and the wind noise generated is small and not easily transmitted into the vehicle cabin. At this time, the adjusting mechanism is used to drive the plurality of spoiler plates to open the corresponding spoiler holes respectively, so that all the spoiler holes on the support frame are opened to facilitate the exhaust of the pressure relief valve. When the vehicle speed gradually increases, the flow rate of the airflow around the pressure relief valve gradually increases, so that the wind noise generated also gradually increases and is easily transmitted into the vehicle cabin. At this time, the adjusting mechanism is used to drive part or all of the spoiler plates to close the corresponding spoiler holes, so as to reduce the wind noise caused by the spoiler holes and the wind noise at the pressure relief valve, thereby improving the driving experience.

[0039] It should be noted that the terms "first", "second", and the like in the description and in the claims of the present application and above-described accompanying drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than that illustrated or described herein.

[0040] In combination Figures 1 to 3 As shown in the drawings, the embodiment of the present application provides a vehicle body pressure relief valve adjusting device 100, comprising a pressure relief valve 1, a spoiler mechanism 2 and an adjusting mechanism 3, the spoiler mechanism 2 comprises a plurality of spoiler plates 21 and a support frame 22 provided with a plurality of spoiler holes 23, the support frame 22 is connected to the pressure relief valve 1, the plurality of spoiler plates 21 are arranged around the pressure relief valve 1 and are respectively arranged at the corresponding spoiler holes 23, and the adjusting mechanism 3 is connected with the spoiler plates 21 and is used to drive the spoiler plates 21 to open or close the corresponding spoiler holes 23.

[0041] Specifically, the pressure relief valve 1 is usually installed on the side wall panel 200 at the rear wheel of the vehicle, the support frame 22 of the spoiler mechanism 2 is usually connected to the valve body of the pressure relief valve 1, and the support frame 22 is provided with a plurality of spoiler holes 23 arranged around the valve body of the pressure relief valve 1, and the plurality of spoiler plates 21 are arranged one by one corresponding to the plurality of spoiler holes 23, that is, the plurality of spoiler plates 21 are also arranged around the valve body of the pressure relief valve 1. The plurality of spoiler plates 21 can be arranged in the inner space of the plurality of spoiler holes 23 respectively, or can be arranged in the outer space of the plurality of spoiler holes 23 respectively, and the spoiler plate 21 can move along the axial direction perpendicular to the corresponding spoiler hole 23 to block the corresponding spoiler hole 23. For example Figure 3 As shown in the drawings, spoiler holes 23 are formed on the upper and lower and front and rear four surfaces of the support frame 22, and each spoiler hole 23 is provided with a spoiler plate 21. The plurality of spoiler plates 21 can be arranged around the pressure relief valve 1 in a whole circle, that is, the spoiler plate 21 and the support frame 22 jointly form a closed annular structure, for example, the support frame 22 and the spoiler plate 21 in the shape of an arc plate can form a circular ring structure or an elliptical ring structure, and the spoiler plate 21 in the shape of a flat plate can form a rectangular ring structure. Figure 3The plurality of spoiler plates 21 can also be arranged on part of the circumference of the pressure relief valve 1, that is, the spoiler plate 21 and the support frame 22 jointly form a half-enclosed structure. In actual application, appropriate selection can be made according to factors such as the assembly position or specific structure of the pressure relief valve 1. Here, no specific limitation is made. Moreover, the plurality of spoiler plates 21 are respectively connected with the adjusting mechanism 3, and the adjusting mechanism 3 is used to drive the spoiler plate 21 to move, so as to open or close the corresponding spoiler hole 23. The adjusting mechanism 3 can be a telescopic mechanism such as a hydraulic cylinder or an electric cylinder, which is used to realize the lifting movement of the spoiler plate 21 to block or expose the spoiler hole 23, so as to realize the closing or opening of the spoiler hole 23. At this time, the adjusting mechanism 3 usually adopts a telescopic mechanism. The adjusting mechanism 3 can also be a telescopic mechanism, which is used to realize the expansion or contraction of the spoiler plate 21 by filling or sucking fluid medium into or out of the cavity of the spoiler plate 21, so as to realize the closing or opening of the spoiler hole 23.

[0042] In the embodiment, the spoiler mechanism 2 is arranged at the pressure relief valve 1, and the support frame 22 of the spoiler mechanism 2 is connected to the pressure relief valve 1, so as to realize the installation and fixation of the spoiler mechanism 2. Moreover, the plurality of spoiler plates 21 of the spoiler mechanism 2 are respectively arranged at the plurality of spoiler holes 23 of the support frame 22 and arranged around the pressure relief valve 1, so as to block the airflow on the side where the spoiler plate 21 is located from entering the pressure relief valve 1 when the spoiler plate 21 closes the corresponding spoiler hole 23, and to reduce the wind noise generated at the pressure relief valve 1. Moreover, the adjusting mechanism 3 is arranged, so as to drive the spoiler plate 21 to open or close the corresponding spoiler hole 23 by using the adjusting mechanism 3. In this way, when the vehicle is running at low speed, the airflow around the pressure relief valve 1 flows slowly, and the wind noise generated is small and is not easy to be transmitted into the vehicle cabin. At this time, the plurality of spoiler plates 21 can be driven to open the corresponding spoiler hole 23 by using the adjusting mechanism 3, so as to open all the spoiler holes 23 on the support frame 22, and facilitate the exhaust of the pressure relief valve 1. When the vehicle speed gradually increases, the flow rate of the airflow around the pressure relief valve 1 gradually increases, so that the wind noise generated gradually increases, and is thus easy to be transmitted into the vehicle cabin. At this time, part or all of the spoiler plates 21 can be driven to close the corresponding spoiler hole 23 by using the adjusting mechanism 3, so as to reduce the wind noise caused by the spoiler hole 23, and to reduce the wind noise at the pressure relief valve 1, and to improve the driving experience.

[0043] Optionally, in combination with Figure 3 and Figure 4 It is shown that the support frame 22 comprises a plurality of supports 221, and the plurality of supports 221 are arranged at intervals around the pressure relief valve 1. The gap between the adjacent two supports 221 in the circumferential direction of the pressure relief valve 1 constitutes the spoiler hole 23.

[0044] Specifically, when the plurality of spoilers 21 and the plurality of supports 221 form a closed ring structure, the number of spoilers 21, spoiler holes 23 and supports 221 is consistent, and when the plurality of spoilers 21 and the plurality of supports 221 form a semi-enclosed structure, the number of spoilers 21 and spoiler holes 23 is consistent, and the number of supports 221 is one more than the number of spoilers 21. For example, when the spoiler 21 is provided with two, the support 221 can be two or three, if the support 221 is two, the two supports 221 are oppositely arranged in the circumferential direction of the pressure relief valve 1, at this time, the two supports 221 divide the circumferential direction of the pressure relief valve 1 into two parts, and form two spoiler holes 23 in the circumferential direction of the pressure relief valve 1, so that two spoilers 21 and two supports 221 form a ring structure; if the support 221 is three, the three supports 221 are arranged in the circumferential direction of the pressure relief valve 1, and the gap between the adjacent two supports 221 constitutes a spoiler hole 23, at this time, two spoilers 21 and three supports 221 form a semi-enclosed structure.

[0045] In the embodiment, the support frame 22 can be composed of a plurality of supports 221 arranged around the pressure relief valve 1, so as to simplify the structure of the support frame 22, reduce the consumption materials, and facilitate the processing and manufacturing, and at the same time, the spacing between the adjacent two supports 221 in the circumferential direction of the pressure relief valve 1 can be used as a spoiler hole 23, so that the opening operation is not needed, the processing flow can be greatly simplified, and the production efficiency is improved.

[0046] Optionally, in combination with Figure 4 As shown in the figure, the support frame 22 further comprises a connecting plate 222, one end of the plurality of supports 221 is connected to the pressure relief valve 1 respectively, and the other end is connected to the connecting plate 222 respectively.

[0047] Specifically, the connecting plate 222 is connected to the plurality of supports 221 away from the pressure relief valve 1, and is located on the side of the pressure relief valve 1 away from the side wall plate 200, so that the support frame 22 as a whole presents a frame structure covering the pressure relief valve 1, and a spoiler hole 23 is formed on each side of the frame structure, for example, upper and lower, front and back, etc.

[0048] In the embodiment, the connecting plate 222 can be arranged at the end of the plurality of supports 221 away from the pressure relief valve 1, so as to block the airflow entering the pressure relief valve 1 along the left and right directions of the vehicle by using the connecting plate 222, thereby further reducing the risk of wind noise at the pressure relief valve 1. In addition, the connecting plate 222 can also limit the displacement of the spoiler 21 when the adjusting mechanism 3 drives the spoiler 21 to rise or expand, so as to prevent the spoiler 21 from exceeding the spoiler hole 23, thereby playing a certain limiting role.

[0049] Further, the connecting plate 222 can also be provided with a turbulence hole 23, and a turbulence plate 21 is arranged at the turbulence hole 23, and the turbulence plate 21 is driven to close or open the turbulence hole 23 on the connecting plate 222 by the adjusting mechanism 3.

[0050] Optionally, the inner wall of the turbulence hole 23 is provided with a first guide structure, and the turbulence plate 21 is provided with a second guide structure, and the second guide structure is used to move relative to the first guide structure along the axial direction perpendicular to the turbulence hole 23.

[0051] Specifically, when the turbulence hole 23 is formed by the spacing between the two adjacent supports 221, the first guide structure is arranged on the support 221. The first guide structure can be one of a guide rail and a sliding block, and the second guide structure is the other one of the guide rail and the sliding block. For example, when the first guide structure is a guide rail and the second guide structure is a sliding block, the guide rail is arranged on the inner wall of the turbulence hole 23 along the axial direction perpendicular to the turbulence hole 23, and the sliding block is usually arranged at the end of the turbulence plate 21 away from the side wall panel 200, as shown in Figure 4 For the vehicle body pressure relief valve adjusting device 100 installed on the left side of the vehicle, the sliding block is arranged at the left end of the turbulence plate 21, and the right end of the turbulence plate 21 is connected to the valve body of the pressure relief valve 1 or the side wall panel 200. For the vehicle body pressure relief valve adjusting device 100 installed on the right side of the vehicle, the left end of the turbulence plate 21 is connected to the valve body of the pressure relief valve 1 or the side wall panel 200, and the sliding block is arranged at the right end of the turbulence plate 21.

[0052] In this embodiment, when the adjusting mechanism 3 drives the turbulence plate 21 to move, the first guide structure and the second guide structure can be used to guide the movement of the turbulence plate 21, so as to ensure that the turbulence plate 21 can move along the set trajectory.

[0053] Optionally, as shown in Figure 2 The adjusting mechanism 3 includes a tank body 31, a pump body 32 and a connecting pipeline 33. The tank body 31 is used to store fluid medium, the turbulence plate 21 has a cavity, one end of the connecting pipeline 33 is connected to the tank body 31 through the pump body 32, and the other end is respectively communicated with the cavities of the plurality of turbulence plates 21. When the pump body 32 delivers fluid medium to the cavities, the turbulence plate 21 expands to block the turbulence hole 23, and when the pump body 32 sucks fluid medium from the cavities, the turbulence plate 21 shrinks to open the turbulence hole 23.

[0054] Specifically, the tank 31 and pump 32 are typically detachably mounted on the side panel 200. The outlet of the tank 31 is connected to the first port of the pump 32 via a connecting pipe 33. The second port of the pump 32 is connected to each of the baffles 21 via the connecting pipe 33 and communicates with the cavity of the baffle 21. In other words, the piping between the multiple baffles 21 is a parallel piping system. The baffles 21 are typically hollow structures that can expand and contract, similar to balloons or airbags. The fluid medium can be gas or liquid. When the pump body 32 delivers fluid medium into the cavity of the baffle 21, the first interface of the pump body 32 is the inlet of the pump body 32, and the second interface of the pump body 32 is the outlet of the pump body 32. At this time, the fluid medium in the tank 31 is filled into the cavity of the baffle 21 under the action of the pump body 32, so that the baffle 21 gradually expands according to the set trajectory until it completely blocks the baffle hole 23, thus achieving the closure of the baffle hole 23. When the pump body 32 draws fluid medium into the cavity of the baffle 21, the first interface of the pump body 32 is the outlet of the pump body 32, and the second interface of the pump body 32 is the inlet of the pump body 32. At this time, the fluid medium in the baffle 21 flows back into the tank 31 under the action of the pump body 32, so that the baffle 21 gradually contracts according to the set trajectory until it completely exposes the baffle hole 23, thus achieving the opening of the baffle hole 23.

[0055] In this embodiment, when the vehicle is traveling at high speed, the pump body 32 can fill or draw fluid medium into the cavity of the spoiler 21 to drive the spoiler 21 to expand or contract in the axial direction perpendicular to the spoiler hole 23, so as to close or open the spoiler hole 23. This allows the adjustment mechanism 3 to automatically adjust the opening and closing state of each spoiler hole 23, making the operation more convenient.

[0056] Optionally, combined Figure 2 As shown, the regulating mechanism 3 also includes a control valve 34. The connecting pipeline 33 includes a main pipeline 331 and multiple branch pipelines 332. One end of the main pipeline 331 is connected to the tank 31 through the pump body 32. One end of each of the multiple branch pipelines 332 is connected to the cavity of each of the multiple baffles 21. The other end of each of the multiple branch pipelines 332 is connected to the other end of the main pipeline 331 through the control valve 34. The control valve 34 is used to control the opening and closing of the branch pipelines 332.

[0057] Specifically, control valve 34 can be installed on each branch pipe 332, such as Figure 2 As shown, at this time, a control valve 34 controls the opening and closing of a branch pipeline 332; the control valve 34 can also be set at the connection between the main pipeline 331 and the branch pipeline 332. In this case, the control valve 34 is provided with multiple passage interfaces, and multiple branch pipelines 332 are respectively connected to different passage interfaces of the control valve 34. The opening and closing of different passage interfaces of the control valve 34 is used to realize the opening and closing of different branch pipelines.

[0058] In this embodiment, the control valve 34 is arranged, and the plurality of branch pipes 332 are arranged to communicate with the main pipe 331 through the control valve 34 at one end away from the spoiler 21, so that the opening and closing of each branch pipe 332 can be controlled by the control valve 34, and the opening and closing of each branch pipe 332 where the spoiler 21 is arranged can be independently controlled, thereby facilitating the automatic adjustment of the opening and closing state of the spoiler hole 23.

[0059] In combination Figure 5 As shown in the figure, another embodiment of the present application provides a vehicle body pressure relief valve adjusting method based on the vehicle body pressure relief valve adjusting device 100 described above, comprising the following steps:

[0060] Step S100, obtaining the adjustment mode selected by the user;

[0061] Step S200, when the adjustment mode is the manual adjustment mode, obtaining the target spoiler hole selected by the user; wherein the target spoiler hole is at least one of the plurality of spoiler holes 23;

[0062] Step S300, controlling the target spoiler hole to close;

[0063] Specifically, a button for controlling the spoiler 21 to close or open the spoiler hole 23 is arranged on the instrument panel of the vehicle, and in the manual adjustment mode, the user controls the opening and closing of the target spoiler hole by pressing the button corresponding to the target spoiler hole, wherein the button can be similar to the key for controlling the opening and closing of the sunroof, or a touch key on the main control screen.

[0064] Step S400, when the adjustment mode is the automatic adjustment mode, controlling the adjusting mechanism 3 to drive the spoiler 21 to open or close the corresponding spoiler hole 23 according to the parameter information of the vehicle, wherein the parameter information includes the driving speed or the sound pressure in the vehicle.

[0065] Specifically, since the driving speed and the sound pressure in the vehicle can directly reflect the wind noise at the pressure relief valve 1, using the driving speed or the sound pressure in the vehicle as the parameter information to determine whether the spoiler hole 23 needs to be closed can improve the accuracy of the control process.

[0066] In this embodiment, the adjustment mode selected by the user can be obtained, and when the user selects the manual adjustment mode, the target spoiler hole selected by the user is obtained, and then the target spoiler hole is controlled to close, so as to realize the manual adjustment of the opening and closing state of each spoiler hole 23 of the vehicle body pressure relief valve adjusting device 100. Alternatively, when the user selects the automatic adjustment mode, the adjusting mechanism 3 can be controlled to drive the spoiler 21 to open or close the corresponding spoiler hole 23 according to the driving speed or the sound pressure in the vehicle, so as to realize the automatic adjustment of the opening and closing state of each spoiler hole 23 of the vehicle body pressure relief valve adjusting device 100.

[0067] Optionally, step S400 specifically comprises:

[0068] Step S410, acquiring parameter information of the vehicle and a plurality of set parameters respectively corresponding to the plurality of spoiler holes 23;

[0069] Step S420, when the parameter information is greater than a target parameter, controlling the adjusting mechanism 3 to drive the spoiler holes 23 corresponding to the set parameters less than or equal to the target parameter in the plurality of set parameters to close; wherein the target parameter is any one of the plurality of set parameters.

[0070] Specifically, when the parameter information is the driving speed of the vehicle, the set parameter is a preset speed, and each spoiler hole 23 corresponds to a different preset speed; when the parameter information is the sound pressure in the vehicle, the set parameter is a preset sound pressure, and each spoiler hole 23 corresponds to a different preset sound pressure; Since the lower side of the pressure relief valve 1 is a position where wind noise is more likely to occur, followed by the rear side, front side and upper side of the pressure relief valve 1, therefore, the value of the set parameter corresponding to the spoiler hole 23 on the lower side of the pressure relief valve 1 is usually set to be smaller, and the values of the set parameters corresponding to the spoiler holes 23 on the rear side, front side and upper side of the pressure relief valve 1 are set to be larger in turn, that is, if the set parameter is set to include a first preset parameter corresponding to the spoiler hole 23 on the lower side, a second preset parameter corresponding to the spoiler hole 23 on the rear side, a third preset parameter corresponding to the spoiler hole 23 on the front side, and a fourth preset parameter corresponding to the spoiler hole 23 on the upper side, the first preset parameter, the second preset parameter, the third preset parameter and the fourth preset parameter increase in turn.

[0071] In this embodiment, when the user selects the automatic adjustment mode, the driving speed of the vehicle or the sound pressure in the vehicle and a plurality of set parameters respectively corresponding to the plurality of spoiler holes 23 are acquired, and then the parameter information is compared with a target parameter, when the parameter information is greater than the target parameter, the adjusting mechanism 3 is controlled to drive the spoiler holes 23 corresponding to the set parameters less than or equal to the target parameter in the plurality of set parameters to close, so as to realize the automatic adjustment of the opening and closing state of each spoiler hole 23 of the vehicle body pressure relief valve adjusting device 100.

[0072] Further, according to the difference of the parameter information, the automatic adjustment mode can be divided into speed adjustment mode and sound pressure adjustment mode, wherein the driving speed of the vehicle changes according to the increasing or decreasing rule, therefore, in the speed adjustment mode, after the driving speed collected at a certain time is greater than a certain preset speed, only the driving speed collected next time needs to be compared with the preset speed in the next order, and the specific control logic is as shown in Figure 6 , and the sound pressure in the vehicle changes according to the step change rule, therefore, in the sound pressure adjustment mode, after the sound pressure in the vehicle is collected each time, the collected sound pressure in the vehicle needs to be compared with each preset sound pressure, and the specific control logic is as shown inFigure 8 For the convenience of understanding, the following is described by way of example. For example, the front side, the rear side, the upper side and the lower side of the pressure relief valve 1 are respectively provided with the spoiler 21 and the spoiler hole 23, and the set parameters include the first preset parameter corresponding to the spoiler hole 23 of the lower side, the second preset parameter corresponding to the spoiler hole 23 of the rear side, the third preset parameter corresponding to the spoiler hole 23 of the front side, and the fourth preset parameter corresponding to the spoiler hole 23 of the upper side, and the first preset parameter, the second preset parameter, the third preset parameter and the fourth preset parameter increase in turn, wherein in the vehicle speed adjustment mode, each preset parameter is a preset vehicle speed, and in the in-vehicle sound pressure adjustment mode, each preset parameter is a preset sound pressure.

[0073] As shown in Figure 6 In the vehicle speed adjustment mode, the driving vehicle speed of the vehicle is first obtained, and then the driving vehicle speed is compared with each preset vehicle speed; when the driving vehicle speed is greater than the first preset vehicle speed (for example, the driving vehicle speed is greater than 60 km / h), the spoiler 21 of the lower side is controlled to close the spoiler hole 23 of the lower side, and the other spoiler holes 23 are kept in an open state; when the driving vehicle speed continues to increase to be greater than the second preset vehicle speed (for example, the driving vehicle speed is greater than 80 km / h), the spoiler hole 23 of the lower side continues to be kept closed, and at the same time, the spoiler 21 of the rear side is controlled to close the spoiler hole 23 of the rear side, and the other spoiler holes 23 are kept in an open state; when the driving vehicle speed continues to increase to be greater than the third preset vehicle speed (for example, the driving vehicle speed is greater than 100 km / h), the spoiler holes 23 of the lower side and the rear side continue to be kept closed, and at the same time, the spoiler 21 of the front side is controlled to close the spoiler hole 23 of the front side, and the other spoiler holes 23 are kept in an open state; when the driving vehicle speed continues to increase to be greater than the fourth preset vehicle speed (for example, the driving vehicle speed is greater than 120 km / h), the spoiler holes 23 of the lower side, the rear side and the front side continue to be kept closed, and at the same time, the spoiler 21 of the upper side is controlled to close the spoiler hole 23 of the upper side.

[0074] As shown in Figure 8As shown, in the vehicle interior sound pressure adjustment mode, the vehicle interior sound pressure is first acquired, and then the vehicle interior sound pressure is compared with each preset sound pressure; when the acquired vehicle interior sound pressure is greater than a first preset sound pressure (for example, the vehicle interior sound pressure is greater than 45 pa), the lower spoiler 21 is controlled to close the lower turbulence holes 23, and the other turbulence holes 23 are kept in an open state; when the vehicle interior sound pressure is greater than a second preset sound pressure (for example, the vehicle interior sound pressure is greater than 48 pa), the lower spoiler 21 and the rear spoiler 21 are controlled to close the lower turbulence holes 23 and the rear turbulence holes 23 respectively, and the other turbulence holes 23 are kept in an open state; when the vehicle interior sound pressure is greater than a third preset sound pressure (for example, the vehicle interior sound pressure is greater than 51 pa), the lower spoiler 21, the rear spoiler 21 and the front spoiler 21 are controlled to close the lower turbulence holes 23, the rear turbulence holes 23 and the front turbulence holes 23 respectively, and the other turbulence holes 23 are kept in an open state; when the vehicle interior sound pressure is greater than a fourth preset sound pressure (for example, the vehicle interior sound pressure is greater than 54 pa), the lower spoiler 21, the rear spoiler 21, the front spoiler 21 and the upper spoiler 21 are controlled to close the lower turbulence holes 23, the rear turbulence holes 23, the front turbulence holes 23 and the upper turbulence holes 23 respectively.

[0075] Optionally, the parameter information includes the vehicle interior sound pressure, and the acquiring of the parameter information of the vehicle in step S410 specifically includes:

[0076] In step S411, the sound pressure of each sound sampling point 300 is acquired.

[0077] In step S412, the vehicle interior sound pressure is determined according to the sound pressure of each sound sampling point 300 and the preset weight proportion corresponding to each sound sampling point 300.

[0078] Specifically, as shown, Figure 7 a plurality of microphones are arranged on the front and rear seats of the vehicle as sound sampling points 300 to collect the vehicle interior sound pressure. The sound pressures collected by the sound sampling points 300 at different positions are usually different, so the plurality of sound sampling points 300 need to be averaged with a certain preset weight proportion when determining the vehicle interior sound pressure. Since the pressure relief valve 1 is located at the rear wheel, far away from the front seats and close to the rear seats, the preset weight proportion corresponding to the sound sampling points 300 on the front seats is usually set to be smaller, and the preset weight proportion corresponding to the sound sampling points 300 on the rear seats is usually set to be larger. For example, four microphones are arranged on the front seats and the rear seats respectively, the preset weight proportions corresponding to the microphones on the front seats are set to be 1 / 16, 1 / 16, 1 / 16 and 1 / 16 from left to right, and the preset weight proportions corresponding to the microphones on the rear seats are set to be 1 / 8, 1 / 4, 1 / 4 and 1 / 8 from left to right. In actual application, the preset weight proportions of the sound sampling points 300 can be adjusted according to real vehicle test, which is not limited here.

[0079] In the embodiment, the sound pressure in the vehicle is determined according to the sound pressure of each sound sampling point 300 at different positions in the vehicle and the preset weight ratio corresponding to each sound sampling point 300, so that the obtained sound pressure in the vehicle is more accurate, the adjustment precision is improved, and the adjustment process of the body pressure relief valve is more reasonable and in line with the actual situation.

[0080] The application further provides a vehicle comprising the body pressure relief valve adjustment device 100 described above, and / or comprising a computer readable storage medium storing a computer program and a processor, wherein when the computer program is read and executed by the processor, the body pressure relief valve adjustment method described above is realized.

[0081] In the embodiment, the vehicle further comprises a side wall plate 200 located at the rear wheel, the pressure relief valve 1 of the body pressure relief valve adjustment device 100 is detachably installed on the side wall plate 200, the spoiler mechanism 2 is connected to the valve body of the pressure relief valve 1, the plurality of spoiler plates 21 of the spoiler mechanism 2 are arranged around the valve body of the pressure relief valve 1, and the adjustment mechanism 3 is detachably installed on the side wall plate 200 and used to drive the spoiler plates 21 to close or open the spoiler holes 23. In addition, the vehicle in the embodiment has the same beneficial effects as the body pressure relief valve adjustment device 100 described above, and details are not described herein.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the application, and these changes and modifications shall fall within the protection scope of the application.
