[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] This embodiment provides a pressure regulating system, which includes a position detection device, a pressure detection device, and such as... Figure 1 and Figure 2 The electric pressure wave protection valve 10 shown includes a position detection device for detecting the current position of the vehicle. The pressure detection device includes a first pressure detection unit and a second pressure detection unit. The first pressure detection unit is used to detect the external pressure of the vehicle, and the second pressure detection unit is used to detect the internal pressure of the vehicle. The electric pressure wave protection valve 10 is used to connect or disconnect the interior and exterior of the vehicle. The electric pressure wave protection valve 10 is electrically connected to the pressure detection device, and the pressure detection device can adjust the opening degree of the electric pressure wave protection valve 10 according to the obtained external pressure and internal pressure of the vehicle.

[0047] Specifically, in this embodiment, taking the application of the pressure regulation system to a rail vehicle as an example, the rail vehicle includes a front end, a rear end, and several carriages connected between the front end and the rear end. The interior of each carriage is a passenger compartment for accommodating passengers. A position detection device is installed on the vehicle to detect the current position of the vehicle. The pressure detection device includes a first pressure detection unit and a second pressure detection unit. The first pressure detection unit is installed on the outside of the vehicle to detect the external pressure of the vehicle, and the second pressure detection unit is installed inside the vehicle to detect the internal pressure of the vehicle. An electric pressure wave protection valve 10 is installed on the vehicle body. When the electric pressure wave protection valve 10 is open, the interior and exterior of the vehicle are connected, and air exchange can occur between the interior and exterior. When the electric pressure wave protection valve 10 is closed, the interior and exterior of the vehicle are isolated, and no gas exchange occurs between the interior and exterior. The electric pressure wave protection valve 10 is electrically connected to the pressure detection device, and the pressure detection device can adjust the opening degree of the electric pressure wave protection valve 10 according to the external pressure and internal pressure of the vehicle obtained by the pressure detection device. When air exchange is required between the inside and outside of the vehicle, the electric pressure wave protection valve 10 opens to ensure that the pressure inside and outside the vehicle tends to be consistent. When there is a sudden change in the air pressure outside the vehicle, the electric pressure wave protection valve 10 closes to prevent the sudden change in air pressure outside the vehicle from affecting the inside of the vehicle, thereby ensuring the stability of the air pressure inside the vehicle and improving passenger comfort.

[0048] Furthermore, the first pressure detection unit includes a plurality of first pressure detection elements, which are spaced apart on the exterior of the vehicle along the vehicle's travel direction. Specifically, in this embodiment, taking a rail vehicle as an example, at least three first pressure detection elements are provided. Along the vehicle's travel direction, at least one pressure detection element is provided at the front, middle carriage, and rear of the vehicle, thereby enabling accurate detection of the pressure outside the vehicle.

[0049] In this embodiment, the pressure value obtained by the first pressure detection device installed at the front of the vehicle is preferably used as the basis for pressure adjustment. The pressure value obtained by the first pressure detection device installed at the front of the vehicle is a certain time earlier than the pressure values ​​obtained by the first pressure detection devices at the middle and rear of the vehicle. The opening of the electric pressure wave protection valve 10 is adjusted according to the pressure value obtained by the first pressure detection device at the front of the vehicle. This allows the electric pressure wave protection valve 10 to perform relevant actions before the pressure wave reaches the passenger compartment, thereby further reducing the possibility of the pressure wave affecting the pressure in the passenger compartment, thus improving the comfort of passengers in the passenger compartment and improving the flexibility and advance of pressure adjustment.

[0050] In this embodiment, preferably, at least three first pressure detection devices are provided for the front, rear and each compartment, and at least one first pressure detection device is provided for the front, middle and rear of the compartment, so as to ensure the accuracy of obtaining the external pressure of the compartment, improve the effectiveness of pressure regulation and ensure the effect of pressure regulation.

[0051] Furthermore, the second pressure detection unit includes a plurality of second pressure detection elements, which are spaced apart on the inner wall of the vehicle along the vehicle's travel direction. Specifically, in this embodiment, taking a rail vehicle as an example, each car is provided with at least three second pressure detection elements. Along the vehicle's travel direction, at least one second pressure detection element is provided at the front, middle, and rear of the car, respectively, for simultaneously detecting the pressure value of the passenger compartment, thereby improving the accuracy of pressure detection in the vehicle's passenger compartment.

[0052] Optionally, in this embodiment, when performing pressure detection in the passenger compartment of the carriage, the pressure values ​​of multiple second pressure detection devices are obtained, and the average value is taken as the pressure value in the passenger compartment. This can reduce the problem of inaccurate pressure measurement caused by local pressure anomalies and improve the accuracy and effectiveness of pressure detection in the passenger compartment of the carriage.

[0053] Optionally, in this embodiment, both the first pressure detection element and the second pressure detection element are digital pressure sensors, which have high accuracy and fast response speed, and can improve the pressure regulation effect and efficiency of the vehicle.

[0054] In another embodiment, a first pressure detection element is provided, which is located at the front of the vehicle to ensure that changes in external pressure can be obtained in a timely manner, thereby improving the effectiveness and timeliness of pressure regulation.

[0055] In another embodiment, each carriage is provided with a second pressure detection device, which is preferably located in the middle of the carriage, thereby minimizing pressure testing errors inside the carriage and improving the reliability and effectiveness of pressure regulation.

[0056] Furthermore, such as Figure 1 and Figure 2 As shown, the electric pressure wave protection valve 10 includes a fixed plate 11, a valve plate 12, and an electric drive assembly 13. The fixed plate 11 is fixedly installed on the vehicle body, and the fixed plate 11 is provided with an opening 111 for connecting the interior and exterior of the vehicle. The valve plate 12 is rotatably connected to the fixed plate 11, and the valve plate 12 is configured to cooperate with the opening 111. The electric drive assembly 13 is connected between the valve plate 12 and the fixed plate 11, and the electric drive assembly 13 can drive the valve plate 12 to rotate relative to the fixed plate 11 to adjust the opening degree of the valve plate 12 relative to the opening 111.

[0057] Specifically, in this embodiment, an installation groove is provided on the vehicle body, which runs through the vehicle body, thereby connecting the interior and exterior of the vehicle. The fixing plate 11 is sealed and installed in the installation groove. The valve plate 12 is configured to cooperate with the opening 111 on the fixing plate 11. When the valve plate 12 is in the closed state, the valve plate 12 completely blocks the opening 111, disconnecting the interior and exterior of the vehicle. This ensures that changes in external pressure do not affect the internal pressure of the vehicle, and thus maintains a relatively suitable pressure range in the passenger compartment when the external pressure changes drastically, ensuring the comfort of passengers in the passenger compartment. When the ambient pressure outside the vehicle is stable, the valve plate 12 rotates relative to the fixing plate 11, thereby opening the opening 111 to a certain degree, ensuring air exchange between the interior and exterior of the vehicle, and thus ensuring the normal operation of the air conditioning system.

[0058] Optionally, in this embodiment, a nut is provided on the vehicle body, and a through hole is provided on the fixing plate 11. After the bolt passes through the through hole, it is threadedly connected to the nut on the vehicle body, thereby fixing the fixing plate 11 to the vehicle body. Rubber seals are provided on the fixing plate 11 and the vehicle body bracket. The rubber seals can seal the gap between the fixing plate 11 and the vehicle body, ensuring the sealing performance between the fixing plate 11 and the vehicle body.

[0059] In another embodiment, the fixing plate 11 can be fixed to the vehicle body by welding. Welding the fixing plate 11 directly to the mounting groove can ensure a good sealing effect between the mounting groove and the fixing plate 11.

[0060] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, the specific shape of the electric pressure wave protection valve 10 matches the shape of the mounting groove opened on the vehicle body. When the cross-section of the mounting groove opened on the vehicle body is rectangular, the corresponding cross-section of the electric pressure wave protection valve 10 is also roughly rectangular. When the cross-section of the mounting groove opened on the vehicle body is square, the corresponding cross-section of the electric pressure wave protection valve 10 is also roughly square. This will not be elaborated further here.

[0061] Preferably, in this embodiment, the electric drive assembly 13 includes a drive motor and a transmission mechanism 132. The transmission mechanism 132 includes a drive shaft 1321, a first connecting rod 1322, and a second connecting rod 1323. The electric pressure wave protection valve 10 also includes two upright plates 14. The two upright plates 14 are parallel and spaced apart on the fixed plate 11, and the two upright plates 14 are located on both sides of the fixed plate 11 along the length direction. An opening 111 is provided between the two upright plates. The drive shaft 1321 is rotatably provided between the two upright plates. The drive motor is installed on the side of one upright plate away from the other upright plate, and the output end of the drive motor is connected to the drive shaft 1321. The first end of the first connecting rod 1322 is fixedly mounted on the transmission shaft 1321, and the first end of the second connecting rod 1323 is rotatably mounted on the valve plate 12. The second end of the first connecting rod 1322 is hinged to the second end of the second connecting rod 1323. When the drive motor drives the transmission shaft 1321 to rotate, the transmission shaft 1321 drives the second connecting rod 1323 to move through the first connecting rod 1322, so that the valve plate 12 rotates relative to the fixed plate 11, so as to ensure that the opening 111 can be easily blocked or opened.

[0062] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, there are two sets of first connecting rod 1322 and second connecting rod 1323. The two sets of first connecting rod 1322 and second connecting rod 1323 are arranged axially at intervals along the transmission shaft 1321, which increases the force points of valve plate 12, thereby increasing the force balance of valve plate 12, making valve plate 12 less prone to deformation, and ensuring the effectiveness of sealing and opening opening 111.

[0063] Preferably, in this embodiment, as Figure 1 and Figure 2 As shown, the electric pressure wave protection valve 10 also includes a sealing element 15, which surrounds the periphery of the opening 111. When the valve plate 12 is in the state of blocking the opening 111, the valve plate 12 squeezes the sealing element 15, thereby ensuring that the electric pressure wave protection valve 10 has good sealing performance.

[0064] Optionally, in this embodiment, the shape of the valve plate 12 and the shape of the opening 111 are both square, and the corresponding sealing element 15 is also square; in another embodiment, the shape of the valve plate 12, the shape of the opening 111 and the shape of the sealing element 15 can also be other shapes, such as circles, etc., which will not be described in detail here.

[0065] Specifically, in this embodiment, the pressure regulating device further includes a control unit, which is electrically connected to the position detection device, the pressure detection device, and the electric pressure wave protection valve 10. The control unit can acquire the pressure value measured by the pressure detection device, and the control unit can drive the electric pressure wave protection valve 10 to move, thereby regulating the action of the electric pressure wave protection valve 10 to ensure that the pressure can be regulated normally.

[0066] Based on the above pressure regulation system, such as Figure 3 As shown in the figure, this embodiment also provides a pressure regulation method, which includes the following steps.

[0067] S10: Obtain the current location of the vehicle and proceed to S20.

[0068] Specifically, in this embodiment, the vehicle's driving route is fixed, and the air pressure changes at each location are also regular. Therefore, the relevant pressure parameters at each location along the vehicle's driving route are stored in the control unit's memory beforehand. The opening degree of the electric pressure wave protection valve 10 is matched based on the relevant pressure parameters at each location, and a table is created showing the opening degree of the electric pressure wave protection valve 10 at each location of the vehicle. When the vehicle is in motion, at any real-time location, the control unit controls the electric pressure wave protection valve 10 to be in the corresponding working state. For example, the gas pressure near ventilation shafts or tunnel entrances / exits may change drastically. To cope with this drastic change, the preset working state of the electric pressure wave protection valve 10 at the corresponding location is set to closed. Similarly, for each location of the vehicle, a preset opening value of the electric pressure wave protection valve 10 is set accordingly to ensure that the pressure in the passenger compartment is always within a suitable range.

[0069] Optionally, before S10, the preset working state of the electric pressure wave protection valve 10 is obtained based on the test run experiment of the vehicle on the current line. The opening value of the electric pressure wave protection valve 10 at any position will be stored in the unit, and the electric pressure wave protection valve 10 will have a corresponding opening value at any position of the vehicle.

[0070] Optionally, before S10, the preset working state of the electric pressure wave protection valve 10 is obtained through simulation analysis, which will not be elaborated here.

[0071] S20. Obtain the first real-time pressure value A outside the vehicle at the vehicle's location, determine whether the first real-time pressure value A is within the first preset pressure range, and if so, the electric pressure wave protection valve 10 maintains the preset working state and proceeds to S30.

[0072] Specifically, in this embodiment, when the vehicle is at any position, the first real-time pressure value A outside the vehicle at that position is obtained by the first pressure detection unit. The first real-time pressure value A is compared with the first preset pressure range stored in the memory of the control unit. If the first real-time pressure value A is within the first preset pressure range, it is determined that the air pressure at this position will not affect the pressure inside the passenger compartment, and the electric pressure wave protection valve can maintain the preset working state.

[0073] Specifically, in this embodiment, the first preset pressure range is defined by a first pressure upper limit and a first pressure lower limit. The first pressure upper limit is the maximum pressure value at which the external pressure of the vehicle will not affect the internal pressure of the vehicle, and the first pressure lower limit is the minimum pressure value at which the external pressure of the vehicle will not affect the internal pressure of the vehicle. Both the first pressure upper limit and the first pressure lower limit can be obtained from actual experiments or through simulation analysis, and are not limited here.

[0074] S20 also includes: if not, closing the electric pressure wave protection valve 10.

[0075] Specifically, in this embodiment, if the first real-time pressure value A is not within the first preset pressure range, it is determined that the external pressure of the vehicle will affect the internal pressure of the vehicle and reduce the comfort of the passenger compartment. In this case, the electric pressure wave protection valve 10 needs to be closed to avoid the above-mentioned effects and ensure the comfort of the passenger compartment.

[0076] S30. Obtain the second real-time pressure value B inside the vehicle at the vehicle's location, and adjust the opening degree of the electric pressure wave protection valve 10 according to the first real-time pressure value A and the second real-time pressure value B.

[0077] Specifically, in this embodiment, due to reasons such as the vehicle carrying passengers, the actual pressure fluctuations may differ from the pre-predicted ones. Therefore, it is necessary to adjust the electric pressure wave protection valve 10 according to the real-time pressure value inside the vehicle to ensure the comfort inside the vehicle.

[0078] Specifically, in this embodiment, based on the preset adjustment, the second real-time pressure value B inside the vehicle at the vehicle's location is obtained, and the second real-time pressure value B inside the vehicle at the vehicle's location is compared with the first real-time pressure value A outside the vehicle at the vehicle's location. If the difference between the two exceeds the limit, the opening of the electric pressure wave protection valve 10 needs to be adjusted to adjust the pressure difference between the inside and outside of the vehicle.

[0079] S30 specifically includes: comparing the difference between the first real-time pressure value A and the second real-time pressure value B with the target difference value c; if AB>c>0 or BA>c>0, then increase the opening of the electric pressure wave protection valve 10; if c>AB>0 or c>BA>0, then maintain the preset working state of the electric pressure wave protection valve 10.

[0080] Specifically, in this embodiment, the limit value of the pressure difference between the inside and outside of the vehicle, i.e., the target difference value c, is stored in the memory of the control unit beforehand. When the difference between the first real-time pressure value A and the second real-time pressure value B is lower than the target difference value c, the pressure difference between the inside and outside of the vehicle is small and will not affect the comfort experience of passengers in the passenger compartment. Therefore, the electric pressure wave protection valve 10 can maintain its current working state, which can reduce the operation of the drive motor and thus reduce energy consumption. When the difference between the first real-time pressure value A and the second real-time pressure value B is higher than the target difference value c, the pressure difference between the inside and outside of the vehicle is large. If it continues to expand, it will increase the discomfort of passengers in the passenger compartment and needs to be intervened. Therefore, it is necessary to increase the opening of the electric pressure wave protection valve 10 to accelerate air exchange, reduce the difference between the first real-time pressure value A and the second real-time pressure value B, and improve the comfort of the passenger compartment.

[0081] Furthermore, before adjusting the electric pressure wave protection valve 10, the following steps are also included: detecting the opening degree of the electric pressure wave protection valve 10 at the current moment; if the opening degree of the electric pressure wave protection valve 10 is at its maximum at this time, then maintaining the working state of the electric pressure wave protection valve 10.

[0082] Specifically, in this embodiment, if the opening of the electric pressure wave protection valve 10 still needs to be increased when the opening is at its maximum, it indicates that the pressure difference between the inside and outside of the vehicle is large. In this case, it can be controlled by increasing the air intake or exhaust of the air conditioner, which will not be elaborated here.

[0083] This embodiment also provides a vehicle that includes the aforementioned pressure regulation system. By incorporating this system, the vehicle can simultaneously adjust the pressure difference between the interior and exterior of the vehicle through both "advance prediction" and "actual pressure difference," ensuring that the vehicle always maintains good comfort and enhancing the passenger experience.

[0084] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
