Description

Technical Field

[0001] This disclosure relates to the field of vehicle manufacturing technology, and more particularly to a pressure relief valve and a vehicle. Background Technology

[0002] The pressure relief valve in the relevant technology is not waterproof. When the vehicle is wading through deep water, water can easily enter the vehicle through the pressure relief valve, affecting the vehicle's use. Utility Model Content

[0003] The purpose of this disclosure is to provide a pressure relief valve and a vehicle to solve the problems in the aforementioned related technologies.

[0004] To achieve the above objectives, one aspect of this disclosure provides a pressure relief valve, comprising:

[0005] The valve body has a pressure relief channel inside, and the outer wall of the valve body has a vent that communicates with the pressure relief channel.

[0006] A sealing cover is located on one side of the valve body and is configured to fit or separate from the outer wall of the valve body so that the sealing cover can close or open the vent.

[0007] The sealing cover has a first position and a second position. In the first position, the sealing cover is attached to the outer wall of the valve body and closes the vent. In the second position, the sealing cover is separated from the outer wall of the valve body and opens the vent.

[0008] In the above technical solution, the sealing cap fits snugly against the outer wall of the valve body, thus sealing the vent. The sealing cap is a closed structure, preventing water from passing through it and thus preventing water from entering the vehicle. The sealing cap can also separate from the outer wall of the valve body, opening the exhaust port and allowing gas inside the vehicle to escape, achieving pressure relief and maintaining a balance of air pressure inside and outside the vehicle. By placing the sealing cap outside the valve body, the vent is covered and sealed from the outside in, ensuring a good seal and guaranteeing waterproof performance, preventing water seepage and other problems.

[0009] In some possible implementations, the pressure relief valve further includes a guide mechanism connected to both the sealing cap and the valve body, wherein the sealing cap is slidably connected to the valve body via the guide mechanism.

[0010] With this design, the sealing cap and the outer wall of the valve body can move along a predetermined trajectory to ensure a proper fit, thereby ensuring waterproofing.

[0011] In some possible implementations, the guiding mechanism includes a slider and a guide, the slider being slidably connected to the guide, and the guide being used to restrict the slider from sliding along a predetermined direction of the guide. One of the valve body and the sealing cover is provided with the slider, and the other is provided with the guide.

[0012] This design facilitates guidance and ensures the correct direction of movement for the slider.

[0013] In some possible implementations, the sliding member is provided on the side of the sealing cover facing the valve body, one end of the sliding member is connected to the sealing cover, the valve body is provided with the guide member, the guide member is constructed as a sleeve, and the other end of the sliding member slides into the sleeve.

[0014] This design facilitates the sliding cooperation between the slider and the guide.

[0015] In some possible implementations, the guide mechanism is provided in multiple ways, and the multiple guide mechanisms are spaced apart along the circumferential edge of the valve body.

[0016] This setting improves the balance of guidance and enhances its effectiveness.

[0017] In some possible implementations, the pressure relief valve further includes a drive mechanism, the valve body is provided with a mounting portion, the drive mechanism is connected to the mounting portion, and the drive mechanism is used to drive the sealing cover to switch between the first position and the second position.

[0018] This setup enables active waterproofing.

[0019] In some possible implementations, the sealing cover has a connecting portion on the side facing the valve body, the valve body has a connecting port, the connecting portion is movably connected to the connecting port, and the drive mechanism is connected to the connecting portion.

[0020] This design facilitates the movement of the sealing cap while avoiding interference with its movement.

[0021] In some possible implementations, the drive mechanism includes a transmission element and a driver, with one end of the transmission element connected to the output end of the driver and the other end of the transmission element connected to the connecting portion.

[0022] This design facilitates the movement of the closed cover.

[0023] In some possible implementations, the driver includes a motor, and the transmission element includes a first rod and a second rod, one end of the first rod being connected to the output end of the motor, the other end of the first rod being hinged to one end of the second rod, and the other end of the second rod being hinged to the connecting portion.

[0024] By setting it up in this way, rotational motion can be converted into linear motion, which in turn moves the closed lid.

[0025] In some possible implementations, the drive mechanism further includes a limiting member connected to the driver, the limiting member having a limiting groove, the first rod being disposed in the limiting groove, the limiting groove being used to limit the rotational position of the first rod.

[0026] This design limits the rotational position of the first lever, preventing damage.

[0027] In some possible implementations, the connecting part includes a connecting frame, a bracket, and a rotating shaft, the bracket being connected within the connecting frame, the rotating shaft being rotatably connected to the bracket, and the driving mechanism being connected to the rotating shaft.

[0028] This configuration facilitates connection with the drive mechanism.

[0029] In some possible implementations, the pressure relief valve further includes a pressure relief vane rotatably connected to the valve body and disposed within the pressure relief channel, the pressure relief vane being configured to open or close the pressure relief channel.

[0030] This setup facilitates venting and pressure relief.

[0031] In some possible implementations, the vent includes an air inlet and an air outlet, the air inlet and the air outlet being located at opposite ends of the valve body, and the sealing cap is used to close the air outlet.

[0032] In some possible implementations, the valve body includes a base, a support frame, and a decorative element. The base is provided with the pressure relief channel and the vent. The support frame is connected to the side of the base facing the closure cover. The decorative element is connected to the support frame. The decorative element and the support frame are used to fit against the closure cover.

[0033] This design ensures both aesthetics and improved security.

[0034] In some possible implementations, the pressure relief valve further includes a sealing ring sandwiched between the valve body and the closure cover.

[0035] This design improves sealing.

[0036] A second aspect of this disclosure also provides a vehicle including the aforementioned pressure relief valve.

[0037] The above technical solution can achieve internal exhaust pressure relief while also being waterproof, preventing water from entering the vehicle through the pressure relief valve when the vehicle is wading through deep water.

[0038] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0054] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0055] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0056] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0057] To maintain the balance of internal and external pressure in a vehicle and prevent damage to the ears due to a sudden increase in pressure when the door is closed, vehicles are usually equipped with a forced ventilation system, also known as a pressure relief valve. This valve is installed at the rear of the vehicle or near the rear wheel arch and releases gas to the outside when the pressure inside the vehicle is too high.

[0058] The pressure relief valve in this technology is not waterproof. When the vehicle is wading through deep water, water can easily enter the vehicle through the valve, affecting its operation. In other words, when the vehicle is wading through water higher than the valve's set height, gaps will appear in the valve, allowing water to enter the vehicle and potentially submerge its internal structures, thus affecting its functionality.

[0059] Therefore, such as Figures 1-8 As shown, one aspect of this disclosure provides a pressure relief valve, including a valve body 1 and a sealing cover 2.

[0060] A pressure relief channel 11 is provided inside the valve body 1, and a vent 12 communicating with the pressure relief channel 11 is provided on the outer wall of the valve body 1. A sealing cover 2 is located on one side of the valve body 1, and the sealing cover 2 is configured to fit or separate from the outer wall of the valve body 1, so that the sealing cover 2 can close or open the vent 12. Specifically, the sealing cover 2 is located on the outside of the valve body 1, and the sealing cover 2 fits or separates from the outer wall of the valve body 1.

[0061] The sealing cover 2 has a first position and a second position. In the first position, the sealing cover 2 is attached to the outer wall of the valve body 1, and the sealing cover 2 closes the vent 12. In the second position, the sealing cover 2 is separated from the outer wall of the valve body 1, and the sealing cover 2 opens the vent 12. The sealing cover 2 can switch between the first position and the second position as needed, so that the vent 12 can switch between a closed or open state.

[0062] The above technical solution, through the installation of a sealing cover 2 that fits snugly against the outer wall of the valve body 1, effectively seals the vent 12. The sealing cover 2 is a closed structure, preventing water from passing through it and entering the vehicle. Conversely, the sealing cover 2 can separate from the outer wall of the valve body 1, opening the exhaust port 122, allowing gas inside the vehicle to escape, thus relieving pressure and maintaining a balance of air pressure inside and outside the vehicle. By placing the sealing cover 2 outside the valve body 1, the vent 12 is effectively sealed from the outside in, ensuring a secure seal and guaranteeing waterproofing, preventing water seepage and other problems.

[0063] Understandably, in the first position, the sealing cover 2 is entirely fitted against the outer wall of the valve body 1, completely covering and sealing the vent 12. The area of ​​the side of the sealing cover 2 that fits against the outer wall of the valve body 1 is larger than the area of ​​the vent 12, thus ensuring a sealing effect. In some examples, the area of ​​the side of the sealing cover 2 that fits against the outer wall of the valve body 1 can be larger than the area of ​​the outer wall of the valve body 1, achieving an even better sealing effect.

[0064] Optionally, in one embodiment of this disclosure, the pressure relief valve further includes a guide mechanism 3, which is connected to both the sealing cover 2 and the valve body 1. The sealing cover 2 is slidably connected to the valve body 1 via the guide mechanism 3. The guide mechanism 3 guides the movement between the sealing cover 2 and the valve body 1, ensuring that the sealing cover 2 and the outer wall of the valve body 1 move along a predetermined trajectory to ensure a proper fit and thus a waterproof effect. The sealing cover 2 can slide relative to the valve body 1 via the guide mechanism 3, facilitating switching between a first position and a second position.

[0065] Optionally, in one embodiment of this disclosure, the guide mechanism 3 includes a sliding member 31 and a guide member 32. The sliding member 31 is slidably connected to the guide member 32, and the guide member 32 is used to restrict the sliding member 31 from sliding along a preset direction. One of the valve body 1 and the sealing cover 2 is provided with the sliding member 31, and the other is provided with the guide member 32.

[0066] In this design, the sliding member 31 and the guide member 32 are slidably engaged. The guide member 32 guides the sliding member 31, causing it to slide along a predetermined direction. This ensures the direction of movement of the sliding member 31 and the movement of the sealing cover 2, allowing it to accurately fit against the outer wall of the valve body 1 and seal the vent 12. In some examples, the sliding member 31 slides along the extension direction of the guide member 32.

[0067] In some examples, the sliding direction of the slider 31 may be perpendicular to the side of the cover 2 facing the valve body 1. That is, both the slider 31 and the guide 32 extend in a direction perpendicular to the side of the cover 2 facing the valve body 1.

[0068] Optionally, in one embodiment of this disclosure, a sliding member 31 is provided on the side of the sealing cover 2 facing the valve body 1. One end of the sliding member 31 is connected to the sealing cover 2. The valve body 1 is provided with a guide member 32, which is constructed as a sleeve. The other end of the sliding member 31 slides into the sleeve.

[0069] In this design, the sliding member 31 is on the sealing cover 2, and the guide member 32 is on the valve body 1. The guide member 32 is a sleeve, and the sliding member 31 slides within the sleeve. The sleeve is fitted onto the sliding member 31, and the side of the sliding member 31 can contact the inner wall of the sleeve. The sleeve restricts the sliding direction of the sliding member 31 without affecting its sliding. The axis of the sleeve is perpendicular to the side of the sealing cover 2 facing the valve body 1. In some examples, the sliding member 31 can be cylindrical, and the sleeve can be a cylindrical structure opened on the valve body 1. Alternatively, the sleeve can be formed on the valve body 1 during manufacturing. The sleeve is a through structure, which allows the sliding member 31 to slide without interfering with its movement.

[0070] Alternatively, in another embodiment of this disclosure, the sealing cover 2 is provided with a guide 32, and the valve body 1 is provided with a slider 31. In other examples, the guide 32 may be a guide rail, and the slider 31 may be a slider.

[0071] Optionally, in one embodiment of this disclosure, multiple guide mechanisms 3 are provided, spaced apart along the circumferential edge of the valve body 1. The multiple guide mechanisms 3 improve guiding balance and guiding effect, facilitating a tight fit between the sealing cover 2 and the outer wall of the valve body 1. In some examples, four guide mechanisms 3 are used, located at the four corners of the valve body 1. Of course, in other examples, the number of guide mechanisms 3 can be adjusted as needed, and this is not a limitation here.

[0072] Alternatively, in another embodiment of this disclosure, the guide mechanism 3 further includes a folding member, the two ends of which are connected to the sealing cover 2 and the valve body 1 respectively. The folding member can be unfolded and folded. Through the folding member, the position of the sealing cover 2 can be restricted so that the sealing cover 2 is accurately fitted to the valve body 1.

[0073] Optionally, in one embodiment of this disclosure, the pressure relief valve further includes a drive mechanism 4, the valve body 1 is provided with a mounting part 13, the drive mechanism 4 is connected to the mounting part 13, and the drive mechanism 4 is used to drive the sealing cover 2 to switch between a first position and a second position.

[0074] The drive mechanism 4 is connected to the mounting part 13, so that the drive mechanism 4 is fixed on the valve body 1. Through the drive integral, the sealing cover 2 can be switched between a first position and a second position to achieve active waterproofing. That is to say, the sealing cover 2 can be controlled to be in the first or second position according to the vehicle's condition. With the help of sensors and controllers, automated control can be achieved. In some examples, when the vehicle needs to wade through water, the sealing cover 2 can be switched to the first position to close the vent 12 and achieve waterproofing. When the vehicle does not need to wade through water, the sealing cover 2 can be switched to the second position to open the vent 12 and achieve exhaust and pressure relief.

[0075] Optionally, in one embodiment of this disclosure, the sealing cover 2 has a connecting portion 21 on the side facing the valve body 1, and the valve body 1 has a connecting port 14. The connecting portion 21 is movably connected to the connecting port 14, and the drive mechanism 4 is connected to the connecting portion 21. The connecting portion 21 facilitates connection with the drive mechanism 4, which in turn drives the sealing cover 2 to move, thereby switching between a first position and a second position.

[0076] The connection port 14 can avoid the connection part 21 when the sealing cover 2 is attached to the outer wall of the valve body 1. In other words, the connection part 21 can slide in the connection port 14 as the sealing cover 2 moves, thereby avoiding interference from the connection part 21 and affecting the sealing cover 2's attachment to the outer wall of the valve body 1.

[0077] Optionally, in one embodiment of this disclosure, the drive mechanism 4 includes a transmission member 41 and a driver 42, one end of the transmission member 41 is connected to the output end of the driver 42, and the other end of the transmission member 41 is connected to the connecting part 21.

[0078] The actuator 42 is connected to the valve body 1, and the transmission component 41 realizes the transmission. The actuator 42 drives the transmission component 41 to move, and the transmission component 41 drives the closing cover 2 to move, thereby realizing the switching of the closing cover 2 to the first position and the second position.

[0079] Optionally, in one embodiment of this disclosure, the driver 42 includes a motor, and the transmission member 41 includes a first rod 411 and a second rod 412. One end of the first rod 411 is connected to the output end of the motor, and the other end of the first rod 411 is hinged to one end of the second rod 412. The other end of the second rod 412 is hinged to the connecting part 21.

[0080] The motor drives the first rod 411 to rotate. Due to the hinge between the first rod 411 and the second rod 412, when the first rod 411 rotates around one end, it will drive the second rod 412 to move, causing the position of the second rod 412 to change. The hinge between the second rod 412 and the connecting part 21 will cause the connecting part 21 to change position after the position of the second rod 412 changes, thereby enabling the sealing cover 2 to switch between the first position and the second position.

[0081] Optionally, in one embodiment of this disclosure, the drive mechanism 4 further includes a limiting member 43 connected to the driver 42. The limiting member 43 is provided with a limiting groove 44, and the first rod 411 is disposed in the limiting groove 44. The limiting groove 44 is used to limit the rotational position of the first rod 411. By providing the limiting member 43, the rotational position of the first rod 411 can be limited, avoiding excessive rotation of the first rod 411, which could cause the sealing cover 2 and the valve body 1 to fail to fit or separate.

[0082] Understandably, the motor drives the first rod 411 to rotate within the limiting groove 44. The two side walls of the limiting groove 44 exert a limiting effect. When the first rod 411 contacts one side wall of the limiting groove 44, the first rod 411 cannot continue to rotate. At this time, the sealing cover 2 can be located in the first position. When the first rod 411 contacts the other side wall of the limiting groove 44, the first rod 411 cannot continue to rotate. At this time, the sealing cover 2 can be located in the second position.

[0083] Alternatively, in another embodiment of this disclosure, the driver 42 includes a motor, and the transmission component 41 includes a worm gear. The worm gear is connected to the output end of the motor, and the worm gear meshes with the worm. One end of the worm is connected to the connecting part 21. The worm gear can convert rotation into linear motion, thereby causing the seal to fit or separate from the outer wall of the valve body 1.

[0084] Optionally, in one embodiment of this disclosure, the connecting part 21 includes a connecting frame 211, a bracket 212, and a rotating shaft 213. The bracket 212 is connected within the connecting frame 211, and the rotating shaft 213 is rotatably connected to the bracket 212. The driving mechanism 4 is connected to the rotating shaft 213. The rotating shaft 213 facilitates the hinged connection between the driving mechanism 4 and the rotating shaft 213, which helps to move the closing cover 2 and avoids rigid interference.

[0085] The second rod 412 extends into the connecting frame 211 and can be connected to the rotating shaft 213. The rotating shaft 213 can rotate relative to the bracket 212, so that the second rod 412 can pull or push the rotating shaft 213, causing the sealing cover 2 to move linearly. In some examples, the connecting frame 211 is a protrusion formed on the side of the sealing cover 2 facing the valve body 1. The bracket 212 is integrally formed with the side of the sealing cover 2 facing the valve body 1. The bracket 212 includes two support plates, and the two ends of the rotating shaft 213 are rotatably connected to the two support plates respectively.

[0086] Alternatively, in another embodiment of this disclosure, the drive mechanism 4 is configured as an electric push rod, which is connected to the connecting part 21 and drives the closed cover 2 to move.

[0087] Optionally, in one embodiment of this disclosure, the pressure relief valve further includes a pressure relief blade 5, which is rotatably connected to the valve body 1 and disposed within the pressure relief channel 11. The pressure relief blade 5 is configured to open or close the pressure relief channel 11.

[0088] The pressure relief vane 5 can close the pressure relief channel 11, preventing external debris from entering the vehicle through it. When pressure relief is needed, the pressure relief vane 5 can open the pressure relief channel 11, allowing it to flow. In other words, when the air pressure inside the vehicle is low, the pressure relief vane 5 closes the pressure relief channel 11, preventing air from escaping to the outside. When the air pressure inside the vehicle is high, the air can push the pressure relief vane 5 to rotate, opening the pressure relief channel 11 and allowing air to escape to the outside.

[0089] In some examples, the pressure relief vane 5 is connected to the valve body 1 via a rotating component. The rotating component may be equipped with a return spring, which can drive the pressure relief vane 5 to rotate and close the pressure relief channel 11. There may be multiple pressure relief vanes 5, which are stacked on top of each other.

[0090] Optionally, in one embodiment of this disclosure, the vent 12 includes an air inlet 121 and an exhaust outlet 122, with the air inlet 121 and the exhaust outlet 122 located at opposite ends of the valve body 1, and the sealing cover 2 used to seal the exhaust outlet 122.

[0091] The air intake 121 communicates with the interior of the vehicle, while the exhaust port 122 communicates with the external environment. Air from inside the vehicle enters the pressure relief channel 11 through the air intake 121, flows through the pressure relief channel 11 to the exhaust port 122, and is discharged into the external environment. The exhaust port 122 is sealed by the sealing cover 2, providing waterproofing from the outside and preventing water from entering the pressure relief channel 11 and the air intake 121, thus protecting the structure of the valve body 1. It is understood that in the first position, the sealing cover 2 is fitted against the outer wall of the valve body 1 where the exhaust port 122 is located, sealing the exhaust port 122.

[0092] In other examples, the cover 2 can be used to seal the air inlet 121 or to prevent water from entering the vehicle.

[0093] Optionally, in one embodiment of this disclosure, the valve body 1 includes a base 15, a support frame 16, and a decorative element 17. The base 15 is provided with a pressure relief channel 11 and a vent 12. The support frame 16 is connected to the side of the base 15 facing the sealing cover 2. The decorative element 17 is connected to the support frame 16. The decorative element 17 and the support frame 16 are used to fit against the sealing cover 2.

[0094] The pressure relief channel 11 is located inside the base 15, and the vent 12 is located on the outer wall of the base 15. The vent 12 includes an air inlet 121 and an air outlet 122. The air inlet 121 and the air outlet 122 are located on the outer walls of both ends of the base 15 and are respectively connected to the pressure relief channel 11.

[0095] The support frame 16 supports the decorative element 17, ensuring its stability. The decorative element 17 serves a decorative function, ensuring aesthetics. Furthermore, by fitting the decorative element 17, support frame 16, and sealing cover 2 together, the contact area and tightness of the fit are increased, thereby improving waterproofing performance. In some examples, the base 15 is an annular frame with a mesh inside. The open sections of the mesh are configured as pressure relief channels 11, allowing the pressure relief blades 5 to adhere to the mesh. In some examples, the support frame 16 is also an annular structure, fitting around the edge of the base 15 facing the sealing cover 2, and the decorative element 17 is also an annular structure, fitting onto the support frame 16.

[0096] Optionally, in one embodiment of this disclosure, the pressure relief valve further includes a sealing ring sandwiched between the valve body 1 and the sealing cover 2. The sealing ring increases the sealing performance between the valve body 1 and the sealing cover 2, improving waterproofing. In some examples, the sealing ring is made of rubber.

[0097] A second aspect of this disclosure also provides a vehicle including the aforementioned pressure relief valve. The pressure relief valve is located at the rear end of the vehicle and is capable of venting air from inside the vehicle to the external environment.
