Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a pressure relief valve module and a vehicle. Background Art

[0002] Currently, vehicle pressure relief valves connect the interior and exterior of the vehicle, regulating internal pressure. These valves are typically installed on the vehicle's bodywork behind the rear wheels. When pressure inside the vehicle is high, air flows out to relieve pressure, creating a one-way flow of air from the interior to the exterior.

[0003] However, when a vehicle is driving through water, water can easily enter the vehicle through the pressure relief valve, causing problems such as rust on the vehicle's sheet metal and damage to electrical components caused by water. Utility Model Content

[0004] This application provides a pressure relief valve module and a vehicle. The pressure relief valve module includes a pressure relief valve and a driver. By designing a detachable connection between the driver and the pressure relief valve, the driver can be used to drive the pressure relief valve to actively close the pressure relief port, thereby improving the vehicle's water resistance when wading.

[0005] In a first aspect, the present application provides a pressure relief valve module. The pressure relief valve module includes a pressure relief valve and a drive member. The pressure relief valve includes a valve body, a valve disc, and a rotating shaft. The valve body surrounds a pressure relief port, and the valve body is provided with a first through hole, which is connected to the pressure relief port. The rotating shaft rotatably connects to the valve body. The rotating shaft includes a first part and a second part. The first part is located at the pressure relief port, and the second part is located at the first through hole and exposed through the first through hole. The valve disc is mounted on the first part, and the valve disc is used to seal or open the pressure relief port when the rotating shaft rotates relative to the valve body. The drive member is located on one side of the valve body, and the drive member is used to drive the rotating shaft to rotate when connected to the second part. The pressure relief valve module has a first state and a second state. In the first state, the drive member is connected to the second part; in the second state, the drive member is separated from the second part.

[0006] In this application, the pressure relief valve module has two states. When a vehicle traverses a flooded section, the pressure relief valve module can be controlled to enter a first state, connecting the driver to the pressure relief valve. The driver then drives the pressure relief valve to close, preventing water from entering the vehicle through the vent. This overcomes the problem of insufficient wading height, eliminates the need for modifications to the vehicle's overall frame, and reduces the cost of achieving this. Furthermore, by driving the pressure relief valve closed, the driver prevents the pressure relief valve from opening due to the impact of flowing water, improving the stability of the vent seal. Furthermore, by driving the pressure relief valve closed, the vehicle's floating time can be increased if it falls into water, giving passengers more time to escape. Furthermore, when the vehicle does not need to wade, the pressure relief valve module can be controlled to enter a second state, disengaging the driver from the pressure relief valve. In this state, the pressure relief valve automatically opens and closes based on its own weight and the pressure differential between the inside and outside of the vehicle, avoiding obstruction by the driver and achieving the function of a traditional pressure relief valve.

[0007] In the present application, the second portion of the rotating shaft is exposed from the first through hole, so that in the first state, the driving member can drive the second portion of the rotating shaft to drive the valve disc to rotate, thereby realizing the opening and closing of the pressure relief port. The rotating shaft is connected to the valve body, and the rotating shaft is rotatably connected to the valve body, so that in the second state, the valve disc can rotate relative to the valve body with the rotating shaft as support under its own weight or driven by the pressure difference, thereby realizing the opening and closing of the pressure relief port and realizing the ventilation and air pressure balance function of the vehicle. By designing the driving member and the rotating shaft to be separable, it is possible to prevent the driving member from hindering the valve disc from driving the rotating shaft to rotate in the second state, and it is also possible to prevent the valve disc from driving the rotating shaft to rotate, thereby preventing the driving member from reversing and being damaged.

[0008] In some possible implementations, the pressure relief valve module also includes a sensor, which is electrically connected to a driver for transmitting a detection signal to the driver. The driver connects to the second part according to the detection signal and drives the rotating shaft to rotate the valve plate to seal the pressure relief port.

[0009] In this implementation, the distance between the water level and the pressure relief port can be detected by the sensor. When the distance is less than a preset value, the sensor can transmit a detection signal to the driving member to activate the driving member, so that the driving member connects to the second part of the rotating shaft and drives the rotating shaft to drive the valve plate to rotate to seal the pressure relief port, preventing external water from entering the pressure relief port, thereby protecting the vehicle and improving the vehicle's wading ability.

[0010] In some possible implementations, the valve body has a top side and a bottom side when installed on a vehicle, the bottom side is closer to the ground than the top side, and the sensor is installed on the bottom side.

[0011] In this implementation, by installing the sensor on the bottom side, the sensor can better detect the distance between the water level and the pressure relief port, thereby improving the accuracy of the detection.

[0012] In some possible implementations, the valve plate includes a first surface and a second surface arranged opposite to each other, and the first surface and the second surface are located on both sides of the rotating shaft; the weight of the valve plate located between the rotating shaft and the second surface is greater than the weight of the valve plate located between the rotating shaft and the first surface.

[0013] In this implementation, by setting the weight of the valve plate between the rotating shaft and the second surface to be greater than the weight of the valve plate between the rotating shaft and the first surface, it is beneficial for the valve plate to seal the pressure relief port according to gravity when the pressure relief valve module is in the second state, so that when the vehicle does not need to be ventilated and the air pressure inside and outside the vehicle is balanced, the valve plate can achieve a normally closed state of the pressure relief port through the weight distribution design on both sides of the rotating shaft, which can prevent external debris from entering the pressure relief port.

[0014] Among them, structural ribs are distributed on the outer surface of the valve plate. The structural ribs can not only enhance the overall structural strength of the valve plate, but also adjust the distribution of the structural ribs at different positions of the valve plate to achieve that the weight of the valve plate between the rotating shaft and the second surface is greater than the weight of the valve plate between the rotating shaft and the first surface.

[0015] A counterweight block can be added between the valve plate and the rotating shaft and the second surface, so that the weight of the valve plate between the rotating shaft and the second surface is greater than the weight of the valve plate between the rotating shaft and the first surface.

[0016] In some possible implementations, the valve plate includes a first surface and a second surface disposed opposite to each other, the first surface and the second surface are located on both sides of the rotating shaft; and the minimum distance between the first surface and the first part is smaller than the minimum distance between the second surface and the first part.

[0017] In this implementation, the rotating shaft is set closer to the first surface relative to the second surface, so that the weight of the valve plate between the rotating shaft and the second surface is greater than the weight of the valve plate between the rotating shaft and the first surface. This is beneficial for the pressure relief valve module to be in the second state. The valve plate seals the pressure relief port according to gravity, so that when the vehicle does not need to be ventilated and the air pressure inside and outside the vehicle is balanced, the valve plate can achieve a normally closed state of the pressure relief port through the weight distribution design on both sides of the rotating shaft, which can prevent external debris from entering the pressure relief port.

[0018] In some possible implementations, the ratio of the minimum distance between the first surface and the first part to the minimum distance between the second surface and the first part is greater than or equal to 1:5. This is not only beneficial for the valve plate to seal the pressure relief port according to gravity when the pressure relief valve module is in the second state, but also beneficial for avoiding the force arm of the driving member connecting the rotating shaft and driving the rotating shaft to drive the valve plate to be too short when the pressure relief module is in the first state, thereby facilitating the driving member to better drive the rotating shaft to drive the valve plate to rotate and achieve the closure of the pressure relief port.

[0019] In some possible implementations, the valve body includes a first frame and a third frame arranged opposite to each other, and a second frame and a fourth frame arranged opposite to each other, the second frame and the fourth frame are connected between the first frame and the third frame, and the first through hole is located in the first frame; the second frame is protruded with a first protrusion; when the valve plate seals the pressure relief port, the valve plate abuts the first protrusion; when the valve plate opens the pressure relief port, the valve plate separates from the first protrusion.

[0020] In this embodiment, the provision of the first protrusion can reduce the contact surface between the valve disc and the valve body when the valve disc seals the pressure relief vent, thereby increasing the pressure at which the valve disc and the valve body contact each other, thereby improving the stability of the valve disc sealing the pressure relief vent. In addition, the first protrusion can limit the valve disc to prevent excessive rotation of the valve disc, thereby facilitating the valve disc sealing the pressure relief vent.

[0021] In some possible implementations, the valve disc is provided with a first buffer pad; when the valve disc seals the pressure relief port, the first buffer pad abuts against the first protrusion; when the valve disc opens the pressure relief port, the first buffer pad separates from the first protrusion.

[0022] In this embodiment, the provision of the first buffer pad reduces the impact force between the valve disc and the first protrusion when the valve disc rotates to seal the pressure relief port, thereby reducing both collision noise and the impact force received by the valve disc, thereby increasing the service life of the valve disc. Furthermore, when the valve disc seals the pressure relief port, the force exerted by the first protrusion on the first buffer pad causes the first buffer pad to deform, thereby partially wrapping around the first protrusion, thereby improving the sealing effect between the first protrusion and the valve disc, and thus improving the effectiveness of the valve disc in sealing the pressure relief port, thereby improving the water seepage prevention capability.

[0023] In some possible implementations, the first buffer pad is provided with a first groove; when the valve disc seals the pressure relief port, the first protrusion is embedded in the first groove; when the valve disc opens the pressure relief port, the first protrusion is disengaged from the first groove.

[0024] In this implementation, a first groove is provided so that when the valve plate seals the pressure relief port, the first protrusion can be better embedded in the first buffer pad, thereby improving the fit between the first protrusion and the first buffer pad, thereby improving the sealing effect between the first protrusion and the valve plate, and further improving the effect of the valve plate sealing the pressure relief port, which is beneficial to improving the anti-water seepage ability.

[0025] In some possible implementations, the fourth frame is provided with a second protrusion; when the valve plate seals the pressure relief port, one side of the valve plate abuts the first protrusion, and the other side of the valve plate abuts the second protrusion; when the valve plate opens the pressure relief port, the valve plate is separated from the first protrusion and the second protrusion.

[0026] In this implementation, the provision of a second protrusion can reduce the contact surface between the valve disc and the valve body when the valve disc seals the pressure relief vent, thereby increasing the pressure at contact between the valve disc and the valve body and thereby improving the stability of the valve disc sealing the pressure relief vent. Furthermore, the second protrusion can limit the valve disc, preventing it from excessively rotating, thereby facilitating the valve disc sealing the pressure relief vent. The first and second protrusions, respectively, limit the valve disc on opposing sides, and together, they form a limit for the valve disc, facilitating the valve disc sealing the pressure relief vent.

[0027] In some possible implementations, the valve disc is provided with a second buffer pad; when the valve disc seals the pressure relief port, the second buffer pad abuts the second protrusion; when the valve disc opens the pressure relief port, the second buffer pad separates from the second protrusion.

[0028] In this embodiment, the provision of a second cushion can reduce the impact force between the valve disc and the second protrusion when the valve disc rotates to seal the pressure relief port. This can reduce both collision noise and the impact force received by the valve disc, thereby increasing the service life of the valve disc. Furthermore, when the valve disc seals the pressure relief port, the force exerted by the second protrusion on the second cushion can cause the second cushion to deform, causing the second cushion to partially wrap around the second protrusion, thereby improving the sealing effect between the second protrusion and the valve disc, and thus improving the valve disc's ability to seal the pressure relief port, thereby enhancing water seepage prevention.

[0029] In some possible implementations, the second buffer pad is provided with a second groove; when the valve disc seals the pressure relief port, the second protrusion is embedded in the second groove; when the valve disc opens the pressure relief port, the second protrusion is disengaged from the second groove.

[0030] In this implementation, a second groove is provided so that when the valve plate seals the pressure relief port, the second protrusion can be better embedded in the second buffer pad, thereby improving the fit between the second protrusion and the second buffer pad, thereby improving the sealing effect between the second protrusion and the valve plate, and further improving the effect of the valve plate sealing the pressure relief port, which is beneficial to improving the anti-water seepage ability.

[0031] In a second aspect, the present application further provides a vehicle, comprising a vehicle body and any of the aforementioned pressure relief valve modules, wherein the vehicle body has a vent, and the pressure relief valve module is installed at the vent.

[0032] In the present application, by applying a pressure relief valve module to a vehicle, the height position of the vent can be changed without modifying the height position of the vent. The electric structure of the pressure relief valve module can be used to actively close the vent, so that when the vehicle wades through water, the pressure relief valve module can block the external water, thereby overcoming the problem of insufficient wading height of the vehicle.

[0057] See also Figures 1A to 1D , Figure 1A is a schematic structural diagram of a vehicle 100 provided in this application in some embodiments; Figure 1B yes Figure 1A A partially enlarged schematic diagram of a position I in the vehicle 100 is shown; Figure 1C is a schematic structural diagram of the vehicle 100 provided in this application in other embodiments; Figure 1D yes Figure 1C A partial enlarged schematic diagram of point II in the vehicle 100 is shown.

[0058] In some embodiments, the vehicle 100 may be, but is not limited to, a sedan, a multi-purpose vehicle (MPV), a sport utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a van, a passenger car, a truck, etc.

[0059] In some embodiments, a vehicle 100 may include a pressure relief valve module 10 and a vehicle body 20. The vehicle body 20 may have a vent 201, and the pressure relief valve module 10 may be installed at the vent 201. The vent 201 may be a vent 201 for an onboard air conditioner. When the door is closed or the air conditioner is turned on for external circulation, the pressure relief valve module 10 opens the vent 201 for ventilation, thereby achieving pressure balance inside and outside the vehicle 100.

[0060] The opening of the vent 201 may be toward the rear of the vehicle body 20 (eg Figure 1A and Figure 1B Alternatively, the opening of the vent 201 may be toward the side of the vehicle body 20 (as shown in FIG. Figure 1C and Figure 1D shown).

[0061] In the existing technology, the ventilation system of a vehicle air conditioner is typically located on both sides of the rear end of the vehicle, below the side panels, and a pressure relief valve is typically snapped onto the vents. When the door is closed or the air conditioner is turned on for external circulation, and the pressure inside the vehicle exceeds the critical value of the pressure relief valve, the one-way valve in the pressure relief valve opens to exhaust air. When the pressure inside the vehicle falls below a certain level, the pressure relief valve automatically closes due to gravity, closing the vents. Currently, vehicles generally use purely mechanical pressure relief valves, which are mature and low-cost.

[0062] The installation height of the pressure relief valve determines the vehicle's wading depth. The current design of the pressure relief valve and vents allows conventional sedans to wade no deeper than 350mm, and SUVs to wade no deeper than 500mm. However, conventional wading depth designs may be insufficient when faced with flooded roads.

[0063] However, if the vents and pressure relief valve are moved upward as a whole, the shape and separation between the vehicle side and the rear bumper need to be modified, which greatly increases the design cost.

[0064] Based on the above technical problems, the present application provides a pressure relief valve module 10, which is applied to the vehicle 100. It is not necessary to modify the height position of the vent 201. The vent 201 can be actively closed through the electric structure of the pressure relief valve module 10, so that when the vehicle 100 wades through water, the external water can be blocked by the pressure relief valve module 10, thereby overcoming the problem of insufficient wading height of the vehicle 100.

[0065] Next, the specific structure of the pressure relief valve module 10 is introduced.

[0066] Please refer to Figure 1D 、 Figure 2A and Figure 2B , Figure 2A yes Figure 1D The structure diagram of the pressure relief valve module 10 in the vehicle 100 shown in some embodiments is in a first state; Figure 2B yes Figure 1D The structure diagram of the pressure relief valve module 10 shown is in the second state.

[0067] In some embodiments, the pressure relief valve module 10 may include a pressure relief valve 1 and a driver 2. The driver 2 and the pressure relief valve 1 can be connected and separated. Specifically, the pressure relief valve module 10 has a first state and a second state. In the first state, the driver 2 is connected to the pressure relief valve 1 so that the driver 2 can drive the pressure relief valve 1 to rotate, so as to achieve active closing and opening of the pressure relief valve 1. In the second state, the driver 2 is connected to the pressure relief valve 1 so that the pressure relief valve 1 is not affected by the force of the driver 2, and the pressure relief valve 1 can be closed and opened according to its own weight and the pressure difference between the inside and outside of the vehicle 100.

[0068] In this embodiment, because the pressure relief valve module 10 has two states, when the vehicle 100 passes through a flooded section, the pressure relief valve module 10 can be controlled to enter the first state, so that the driver 2 is connected to the pressure relief valve 1. The driver 2 drives the pressure relief valve 1 to close, thereby preventing water from outside the vehicle 100 from entering through the vent 201. This overcomes the problem of insufficient wading height of the vehicle 100 and eliminates the need to improve the overall frame of the vehicle 100, reducing the cost required to overcome the wading height. In addition, by driving the pressure relief valve 1 to close by the driver 2, the pressure relief valve 1 can be opened due to the impact of flowing water, thereby improving the sealing stability of the vent 201. In addition, by driving the pressure relief valve 1 to close by the driver 2, the floating time of the vehicle 100 can be increased when the vehicle 100 falls into the water, thereby giving the passengers more time to escape. In addition, on roads that do not require wading, the pressure relief valve module 10 can be controlled to enter the second state to separate the driving component 2 from the pressure relief valve 1. At this time, the pressure relief valve 1 can automatically adjust the opening and closing by its own weight and the pressure difference between the inside and outside of the vehicle 100, avoiding obstruction by the driving component 2 to achieve the function of the traditional pressure relief valve 1.

[0069] Illustratively, the pressure relief valve 1 may include a valve body 11, a valve disc 12, and a rotating shaft 13. The valve body 11 encloses a pressure relief port 111 and is provided with a first through-hole 112, which communicates with the pressure relief port 111. The rotating shaft 13 is rotatably connected to the valve body 11 and may include a first portion 13a and a second portion 13b. The first portion 13a is located at the pressure relief port 111, and the second portion 13b is located at the first through-hole 112 and exposed through the first through-hole 112. The valve disc 12 may be mounted on the first portion 13a and is configured to seal or open the pressure relief port 111 when the rotating shaft 13 rotates relative to the valve body 11. The driving member 2 is located on one side of the valve body 11 and is configured to drive the rotating shaft 13 to rotate when connected to the second portion 13b. In a first state, the driving member 2 is connected to the second portion 13b, and in a second state, the driving member 2 is separated from the second portion 13b.

[0070] In this embodiment, the second portion 13b of the rotating shaft 13 is exposed from the first through hole 112, so that in the first state, the driver 2 can drive the second portion 13b of the rotating shaft 13 to drive the valve disc 12 to rotate, thereby opening and closing the pressure relief port 111. The rotating shaft 13 is connected to the valve body 11, and the rotating shaft 13 is rotatably connected to the valve body 11, so that in the second state, the valve disc 12 can rotate relative to the valve body 11 with the rotating shaft 13 as support under its own weight or driven by the pressure difference, thereby opening and closing the pressure relief port 111, and realizing the ventilation and air pressure balancing functions of the vehicle 100. By designing the driver 2 and the rotating shaft 13 to be separable, it is possible to prevent the driver 2 from obstructing the valve disc 12 from driving the rotating shaft 13 to rotate in the second state, and it is also possible to prevent the valve disc 12 from driving the rotating shaft 13 to rotate, thereby preventing the driver 2 from reversing and causing damage.

[0071] The valve body 11 may include a first frame 113 and a third frame 115 disposed opposite to each other, and a second frame 114 and a fourth frame 116 disposed opposite to each other. The second frame 114 and the fourth frame 116 are connected between the first frame 113 and the third frame 115, and the first through hole 112 is located in the first frame 113. When the pressure relief valve module 10 is installed in the vent 201 of the vehicle 100, the fourth frame 116 is closer to the ground than the second frame 114.

[0072] In some examples, the second portion 13b of the rotating shaft 13 passes through the first through-hole 112 and is rotatably connected to the first frame 113. The end of the first portion 13a of the rotating shaft 13 away from the second portion 13b is rotatably connected to the third frame 115. In this embodiment, the rotating shaft 13 is connected between the first frame 113 and the third frame 115, and the portion of the rotating shaft 13 located between the first frame 113 and the third frame 115 is fixedly connected to the valve disc 12, so that the valve disc 12 and the rotating shaft 13 can rotate together, thereby improving the stability of the rotation of the valve disc 12.

[0073] In other examples, the second portion 13b of the rotating shaft 13 passes through the first through-hole 112 and is rotatably connected to the first frame 113. The first portion 13a of the rotating shaft 13 is fixedly connected to the valve disc 12. A protrusion is provided at the end of the valve disc 12 away from the second portion 13b of the rotating shaft 13, and the protrusion is rotatably connected to the third frame 115. In this embodiment, because the end of the valve disc 12 away from the second portion 13b of the rotating shaft 13 can be rotatably connected to the third frame 115 via the protrusion, the overall length of the rotating shaft 13 can be shortened. The first portion 13a of the rotating shaft 13 only needs to be fixedly connected to the valve disc 12, which can reduce material costs.

[0074] For example, the pressure relief valve module 10 may further include a transmission member 3 mounted on the driving member 2. In a first state, the transmission member 3 may be connected to the second portion 13b of the rotating shaft 13. In a second state, the transmission member 3 may be separated from the second portion 13b of the rotating shaft 13. In this embodiment, the design of the transmission member 3 enables the pressure relief valve module 10 to switch between the first and second states.

[0075] The transmission member 3 can realize the driving connection and separation between the driving member 2 and the rotating shaft 13 by means of telescoping, clamping, etc.

[0076] Please refer to Figure 3A and Figure 3B , Figure 3A is a schematic structural diagram of the transmission member 3 connected to the rotating shaft 13 in some embodiments; Figure 3B yes Figure 3A The schematic diagram of the structure shows that the transmission member 3 is separated from the rotating shaft 13.

[0077] In some embodiments, the driver 2 may include a housing 21 and a first output shaft 22, with a portion of the first output shaft 22 located within the housing 21 and the remaining portion exposed from the housing 21. The transmission member 3 may include a linear motor 31. The linear motor 31 is fixedly mounted to the first output shaft 22 and has a second output shaft 311. The second output shaft 311 can move linearly along the arrangement direction of the driver 2 and the pressure relief valve 1.

[0078] In this embodiment, the linear motor 31 can be driven to move the second output shaft 311 toward the rotating shaft 13, thereby achieving a fixed connection between the second output shaft 311 and the second portion 13b of the rotating shaft 13, thereby achieving a driving connection between the driving member 2 and the rotating shaft 13. At this time, the pressure relief valve module 10 enters the first state, and the driving member 2 can drive the rotating shaft 13 to rotate, thereby driving the valve disc 12 to rotate, and thus achieving active closure of the pressure relief port 111. In addition, the linear motor 31 can also move the second output shaft 311 away from the rotating shaft 13 to separate the second output shaft 311 from the second portion 13b of the rotating shaft 13, thereby disconnecting the driving connection between the driving member 2 and the rotating shaft 13, thereby preventing the transmission member 3 from obstructing the rotation of the rotating shaft 13 by the valve disc 12.

[0079] For example, the second output shaft 311 and the second portion 13b of the rotating shaft 13 can be secured via a snap-fitting slot, facilitating quick connection and disconnection of the second output shaft 311 from the rotating shaft 13. The slot can have a polygonal, elliptical, or irregular cross-section, enabling the linear motor 31 to rotate after the second output shaft 311 is connected to the rotating shaft 13, thereby driving the rotating shaft 13 to rotate together, thereby improving the stability of both rotations. For example, the slot can have a triangular, rectangular, or prismatic cross-section, without limitation.

[0080] In some examples, the outer diameter of the second output shaft 311 may be larger than the outer diameter of the second portion 13 b of the rotating shaft 13 , and the locking groove is recessed on the surface of the second output shaft 311 facing the rotating shaft 13 .

[0081] In other examples, the outer diameter of the second portion 13 b of the rotating shaft 13 may be larger than the outer diameter of the second output shaft 311 , and the slot is recessed on the surface of the second portion 13 b of the rotating shaft 13 facing the second output shaft 311 .

[0082] In some other embodiments, multiple slots may be provided to cooperate with multiple protruding columns to achieve the snap connection, which is not limited here.

[0083] Please refer to Figure 4A and Figure 4B , Figure 4A is a schematic structural diagram of the transmission member 3 connected to the rotating shaft 13 in other embodiments; Figure 4B yes Figure 4A The schematic diagram of the structure in which the transmission member 3 is separated from the rotating shaft 13 is shown. Figure 4A and Figure 4B The pressure relief valve module 10 shown may include Figure 3A and Figure 3B Some structural features of the pressure relief valve module 10 are shown, and the same structural features are not repeated here.

[0084] In some embodiments, the transmission member 3 may include a first magnet 32 ​​and a second magnet 33 . The first magnet 32 ​​is fixedly mounted on the first output shaft 22 of the driver 2 . The second magnet 33 can move axially relative to the first magnet 32 ​​along the rotating shaft 13 .

[0085] In this embodiment, the first magnet 32 ​​can be an electromagnetic structure. By energizing the first magnet 32 ​​to drive the second magnet 33 toward the rotating shaft 13, the second magnet 33 can be brought into contact with the second portion 13b of the rotating shaft 13 to achieve engagement, thereby achieving a drive connection between the driver 2 and the rotating shaft 13. At this time, the pressure relief module enters the first state, and the driver 2 can drive the rotating shaft 13 to rotate, thereby driving the valve plate 12 to move, and then achieving active closure of the pressure relief port 111. By energizing the first magnet 32 ​​in the reverse direction, the second magnet 33 can be driven to move in a direction away from the rotating shaft 13 to separate the second magnet 33 from the second portion 13b of the rotating shaft 13, thereby disconnecting the drive connection between the driver 2 and the rotating shaft 13, thereby preventing the transmission member 3 from obstructing the rotation of the rotating shaft 13 driven by the valve plate 12.

[0086] In some examples, the first magnet 32 ​​can be a spiral coil in a tubular shape, and the second magnet 33 is partially located inside the first magnet 32 ​​to form a cannon-type electromagnetic structure. When the first magnet 32 ​​is energized, the second magnet 33 can be pushed toward the rotating shaft 13 by magnetic force. When the first magnet 32 ​​is energized in the opposite direction, the second magnet 33 can be sucked back by magnetic force.

[0087] In other examples, the first magnet 32 ​​may be a planar coil, and the second magnet 33 may be driven by utilizing the Lorentz force generated by the first magnet 32 ​​and the second magnet 33 when energized.

[0088] In some other embodiments, the first magnet 32 ​​may be an electromagnet. By changing the direction of the current in the first magnet 32 ​​, the polarity of the magnetic pole surface of the first magnet 32 ​​facing the second magnet 33 is changed, thereby changing the direction of the magnetic driving force on the second magnet 33 .

[0089] The clamping method of the second magnet 33 and the second portion 13 b of the rotating shaft 13 may refer to the aforementioned embodiment and will not be described in detail here.

[0090] Please refer to Figure 5A and Figure 5B , Figure 5A is a schematic structural diagram of the transmission member 3 connected to the rotating shaft 13 in some other embodiments; Figure 5B yes Figure 5A The schematic diagram of the structure in which the transmission member 3 is separated from the rotating shaft 13 is shown. Figure 5A and Figure 5B The pressure relief valve module 10 shown may include Figure 4A and Figure 4B Some structural features of the pressure relief valve module 10 are shown, and the same structural features are not repeated here.

[0091] In some embodiments, the transmission member 3 may include a fixed portion 34 and an electromagnet 35, wherein the fixed portion 34 is fixedly connected to the first output shaft 22 of the driving member 2, and the electromagnet 35 is slidably connected to the fixed portion 34. A third magnet 14 may be provided at an end of the second portion 13b of the rotating shaft 13 near the transmission member 3, and the third magnet 14 has a magnetic pole surface facing the transmission member 3.

[0092] In this embodiment, by changing the direction of the current flowing through the electromagnet 35, the polarity of the surface of the electromagnet 35 facing the rotating shaft 13 can be changed, thereby achieving a conversion between a magnetic attraction and a magnetic repulsion between the electromagnet 35 and the third magnet 14. When a magnetic attraction is formed between the electromagnet 35 and the third magnet 14, the electromagnet 35 moves relative to the fixing portion 34 toward the third magnet 14, enabling the electromagnet 35 to engage with the second portion 13b of the rotating shaft 13, thereby achieving a driving connection between the driver 2 and the rotating shaft 13. At this point, the pressure relief module enters the first state, and the driver 2 can drive the rotating shaft 13 to rotate, thereby driving the valve disc 12 to move, thereby achieving active closure of the pressure relief port 111. By reversing the current flowing through the electromagnet 35, the electromagnet 35 can be driven to move away from the third magnet 14, thereby separating the electromagnet 35 from the second portion 13b of the rotating shaft 13, thereby severing the driving connection between the driver 2 and the rotating shaft 13 and preventing the transmission member 3 from obstructing the rotation of the rotating shaft 13 by the valve disc 12.

[0093] The clamping method of the electromagnet 35 and the second portion 13b of the rotating shaft 13 can refer to the above embodiment and will not be described in detail here.

[0094] Please refer to Figure 1D and Figure 6 , Figure 6 1 is a schematic structural diagram of the valve plate 12 sealing the pressure relief port 111 in some embodiments.

[0095] In some embodiments, the second frame 114 may be provided with a first protrusion 1141 . When the valve disc 12 seals the pressure relief port 111 , the valve disc 12 abuts against the first protrusion 1141 . When the valve disc 12 opens the pressure relief port 111 , the valve disc 12 separates from the first protrusion 1141 .

[0096] In this embodiment, the provision of the first protrusion 1141 can reduce the contact surface between the valve disc 12 and the valve body 11 when the valve disc 12 seals the pressure relief port 111, thereby increasing the pressure at which the valve disc 12 and the valve body 11 contact each other, thereby improving the stability of the valve disc 12 in sealing the pressure relief port 111. Furthermore, the first protrusion 1141 can limit the valve disc 12 to prevent excessive rotation of the valve disc 12, thereby facilitating the valve disc 12 sealing the pressure relief port 111.

[0097] In some embodiments, the fourth frame 116 may be provided with a second protrusion 1161. When the valve plate 12 seals the pressure relief port 111, one side of the valve plate 12 abuts against the first protrusion 1141, and the other side of the valve plate 12 abuts against the second protrusion 1161. When the valve plate 12 opens the pressure relief port 111, the valve plate 12 is separated from the first protrusion 1141 and the second protrusion 1161.

[0098] In this embodiment, the provision of the second protrusion 1161 can reduce the contact surface between the valve disc 12 and the valve body 11 when the valve disc 12 seals the pressure relief port 111, thereby increasing the pressure at which the valve disc 12 contacts the valve body 11 and thereby improving the stability of the valve disc 12 in sealing the pressure relief port 111. Furthermore, the second protrusion 1161 can limit the valve disc 12, preventing it from excessively rotating and facilitating its sealing of the pressure relief port 111. The first protrusion 1141 and the second protrusion 1161 respectively limit the valve disc 12 on opposite sides, and together, they limit the valve disc 12, facilitating its sealing of the pressure relief port 111.

[0099] Please refer to Figure 1D and Figure 7 , Figure 7 1 is a schematic structural diagram of the valve plate 12 sealing the pressure relief port 111 in other embodiments.

[0100] In some embodiments, the valve disc 12 may be provided with a first buffer pad 121 . When the valve disc 12 seals the pressure relief port 111 , the first buffer pad 121 abuts against the first protrusion 1141 . When the valve disc 12 opens the pressure relief port 111 , the first buffer pad 121 separates from the first protrusion 1141 .

[0101] In this embodiment, the provision of the first buffer pad 121 can reduce the impact force between the valve disc 12 and the first protrusion 1141 when the valve disc 12 rotates to seal the pressure relief port 111. This can reduce both collision noise and the impact force received by the valve disc 12, thereby increasing the service life of the valve disc 12. In addition, when the valve disc 12 seals the pressure relief port 111, the force exerted on the first buffer pad 121 by the first protrusion 1141 can cause the first buffer pad 121 to deform, thereby causing the first buffer pad 121 to partially wrap around the first protrusion 1141, thereby improving the sealing effect between the first protrusion 1141 and the valve disc 12, and further improving the effectiveness of the valve disc 12 in sealing the pressure relief port 111, thereby facilitating improved water seepage prevention.

[0102] The first buffer pad 121 may be made of elastic materials such as rubber, silicone, and foam.

[0103] In some embodiments, the valve disc 12 may be provided with a second buffer pad 122 . When the valve disc 12 seals the pressure relief port 111 , the second buffer pad 122 abuts against the second protrusion 1161 . When the valve disc 12 opens the pressure relief port 111 , the second buffer pad 122 separates from the second protrusion 1161 .

[0104] In this embodiment, the provision of the second buffer pad 122 can reduce the impact force between the valve disc 12 and the second protrusion 1161 when the valve disc 12 rotates to seal the pressure relief port 111. This can reduce both collision noise and the impact force received by the valve disc 12, thereby increasing the service life of the valve disc 12. Furthermore, when the valve disc 12 seals the pressure relief port 111, the force exerted on the second buffer pad 122 by the second protrusion 1161 can cause the second buffer pad 122 to deform, thereby causing the second buffer pad 122 to partially wrap around the second protrusion 1161, thereby improving the sealing effect between the second protrusion 1161 and the valve disc 12, and thus improving the effectiveness of the valve disc 12 in sealing the pressure relief port 111, thereby facilitating improved water seepage prevention.

[0105] The second buffer pad 122 can be made of elastic materials such as rubber, silicone, and foam.

[0106] Please refer to Figure 1D and Figure 8 , Figure 8 1 is a schematic structural diagram of the valve plate 12 sealing the pressure relief port 111 in some other embodiments.

[0107] In some embodiments, the first buffer pad 121 is provided with a first groove 1211 . When the valve disc 12 seals the pressure relief port 111 , the first protrusion 1141 is embedded in the first groove 1211 . When the valve disc 12 opens the pressure relief port 111 , the first protrusion 1141 is disengaged from the first groove 1211 .

[0108] In this embodiment, the first groove 1211 is provided so that when the valve plate 12 seals the pressure relief port 111, the first protrusion 1141 can be better embedded in the first buffer pad 121, thereby improving the fit between the first protrusion 1141 and the first buffer pad 121, thereby improving the sealing effect between the first protrusion 1141 and the valve plate 12, and further improving the effect of the valve plate 12 sealing the pressure relief port 111, which is beneficial to improving the anti-water seepage ability.

[0109] In some embodiments, the second buffer pad 122 may be provided with a second groove 1221 . When the valve plate 12 seals the pressure relief port 111 , the second protrusion 1161 is embedded in the second groove 1221 . When the valve plate 12 opens the pressure relief port 111 , the second protrusion 1161 is disengaged from the second groove 1221 .

[0110] In this embodiment, a second groove 1221 is provided so that when the valve plate 12 seals the pressure relief port 111, the second protrusion 1161 can be better embedded in the second buffer pad 122, thereby improving the fit between the second protrusion 1161 and the second buffer pad 122, thereby improving the sealing effect between the second protrusion 1161 and the valve plate 12, and further improving the effect of the valve plate 12 sealing the pressure relief port 111, which is beneficial to improving the anti-water seepage ability.

[0111] Please refer to Figure 8 and Figure 9 , Figure 9 Schematic diagram of the structure of the valve plate 12 in some embodiments.

[0112] In some embodiments, the valve plate 12 may include a first surface 123 and a second surface 124 disposed opposite each other, with the first surface 123 and the second surface 124 located on either side of the rotating shaft 13. The weight of the valve plate 12 located between the rotating shaft 13 and the second surface 124 is greater than the weight of the valve plate 12 located between the rotating shaft 13 and the first surface 123. When the pressure relief valve module 10 is installed in the vehicle 100, the second surface 124 is closer to the ground than the first surface 123.

[0113] In this embodiment, by setting the weight of the valve plate 12 between the rotating shaft 13 and the second surface 124 to be greater than the weight of the valve plate 12 between the rotating shaft 13 and the first surface 123, it is beneficial for the pressure relief valve module 10 to be in the second state. The valve plate 12 can seal the pressure relief port 111 according to gravity, so that when the vehicle 100 does not need to be ventilated and the air pressure inside and outside the vehicle 100 is balanced, the valve plate 12 can achieve a normally closed state of the pressure relief port 111 through the weight distribution design on both sides of the rotating shaft 13, and can prevent external debris from entering the pressure relief port 111.

[0114] In some examples, structural ribs are distributed on the outer surface of the valve plate 12. The structural ribs can not only enhance the overall structural strength of the valve plate 12, but also adjust the distribution of the structural ribs at different positions of the valve plate 12 to achieve that the weight of the valve plate 12 between the rotating shaft 13 and the second surface 124 is greater than the weight of the valve plate 12 between the rotating shaft 13 and the first surface 123.

[0115] In other examples, a counterweight 125 can be added between the valve plate 12 and the rotating shaft 13 and the second surface 124, and the counterweight 125 can be used to ensure that the weight of the valve plate 12 between the rotating shaft 13 and the second surface 124 is greater than the weight of the valve plate 12 between the rotating shaft 13 and the first surface 123.

[0116] It should be noted that, in this embodiment, the shaft 13 can be located at any position of the valve disc 12, as long as the weight of the valve disc 12 between the shaft 13 and the second surface 124 is greater than the weight of the valve disc 12 between the shaft 13 and the first surface 123.

[0117] Please refer to Figure 8 and Figure 10 , Figure 10 Schematic diagram of the structure of the valve plate 12 in other embodiments.

[0118] In some embodiments, the minimum distance between the first surface 123 and the first portion 13a of the shaft 13 (see Figure 10 d1) may be less than the minimum distance between the second surface 124 and the first portion 13a (see Figure 10 d2 in the example).

[0119] In this embodiment, by setting the rotating shaft 13 close to the first surface 123 relative to the second surface 124, the weight of the valve plate 12 between the rotating shaft 13 and the second surface 124 is greater than the weight of the valve plate 12 between the rotating shaft 13 and the first surface 123. This is beneficial for the pressure relief valve module 10 to be in the second state. The valve plate 12 can seal the pressure relief port 111 according to gravity, so that when the vehicle 100 does not need to be ventilated and the air pressure inside and outside the vehicle 100 is balanced, the valve plate 12 can achieve a normally closed state of the pressure relief port 111 through the weight distribution design on both sides of the rotating shaft 13, thereby preventing external debris from entering the pressure relief port 111.

[0120] Exemplarily, the ratio of the minimum distance between the first surface 123 and the first part 13a to the minimum distance between the second surface 124 and the first part 13a can be greater than or equal to 1:5. This is not only beneficial for the valve plate 12 to seal the pressure relief port 111 according to gravity when the pressure relief valve module 10 is in the second state, but also beneficial for avoiding the force arm of the driving member 2 connecting to the rotating shaft 13 and driving the rotating shaft 13 to drive the valve plate 12 to be too short when the pressure relief module is in the first state, thereby facilitating the driving member 2 to better drive the rotating shaft 13 to drive the valve plate 12 to rotate to achieve the closure of the pressure relief port 111.

[0121] For example, the ratio of the minimum distance between the first surface 123 and the first part 13a to the minimum distance between the second surface 124 and the first part 13a can be, but is not limited to, 1:2, or 1:2.5, or 1:3, or 1:3.5, or 1:4, or 1:4.5, or 1:5, or other values ​​greater than 1:5, etc.

[0122] Please refer to Figure 1D and Figure 11 , Figure 11 FIG. 1 is a schematic structural diagram of a pressure relief valve module 10 in which a sensor 4 is installed in some embodiments.

[0123] In some embodiments, the pressure relief valve module 10 may further include a sensor 4, which is electrically connected to the driver 2 and is used to transmit a detection signal to the driver 2. The driver 2 connects to the second part 13b according to the detection signal, and drives the rotating shaft 13 to drive the valve plate 12 to rotate to seal the pressure relief port 111.

[0124] In this embodiment, the distance between the water level and the pressure relief port 111 can be detected by the sensor 4. When the distance is less than a preset value, the sensor 4 can transmit a detection signal to the driving member 2 to activate the driving member 2 to work, so that the driving member 2 connects to the second part 13b of the rotating shaft 13, and drives the rotating shaft 13 to drive the valve plate 12 to rotate to seal the pressure relief port 111, preventing external water from entering the pressure relief port 111, thereby protecting the vehicle 100 and improving the wading ability of the vehicle 100.

[0125] It should be noted that when the driving member 2 is connected to the rotating shaft 13, when the sensor 4 detects that the distance between the water level and the pressure relief port 111 is greater than a preset value, the sensor 4 can transmit a release signal to the driving member 2 to disconnect the driving member 2 from the rotating shaft 13.

[0126] For example, the valve body 11 may have a top side 117 and a bottom side 118 when mounted on the vehicle 100 , wherein the bottom side 118 is closer to the ground than the top side 117 . The sensor 4 may be mounted on the bottom side 118 .

[0127] In this embodiment, by installing the sensor 4 on the bottom side 118 , the sensor 4 can better detect the distance between the water level and the pressure relief port 111 , thereby improving the detection accuracy.

[0128] It should be noted that the sensor 4 can also be installed at other positions of the valve body 11 as long as the distance between the water level and the pressure relief port 111 can be achieved.

[0129] It should be noted that the distance between the water level detected by sensor 4 and the pressure relief port 111 is not limited to a specific distance value, and can also be whether sensor 4 detects the presence of an object. Specifically, when sensor 4 is a distance detection sensor, sensor 4 can detect the specific distance value between the water level and the pressure relief port 111. When sensor 4 is a contact sensor (such as a capacitive sensor), sensor 4 is triggered when the sensor is immersed in water to detect the water level.

[0130] In other embodiments, the driver 2 can be controlled by a controller. The controller can be electrically connected to the driver 2 and the sensor 4. The controller can control the driver 2 by receiving information detected by the sensor 4 to connect and disconnect the driver 2 from the second portion 13b. The controller can also control the connection and disconnection of the driver 2 from the second portion 13b via user commands to switch the pressure relief valve module 10 between the first state and the second state. The controller can be installed in a vehicle console, and its user control functions can be implemented through a control panel.

[0131] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0132] It should be noted that all the above drawings are for illustrative purposes only and do not represent the actual size of the product. Furthermore, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.

[0133] The above are only some of the embodiments and implementations of this application. The scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
