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 water-blocking structure of the pressure relief valve in the relevant technology is mainly used to prevent water from entering the dry area of ​​the vehicle through the pressure relief valve when the vehicle is being washed or it is raining. However, if the angle of the pressure relief valve changes, the residual water may seep in, causing damage to the vehicle interior or related components. 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: Valve body; An air curtain, which is rotatably connected to the valve body; The first water-blocking component is connected to the valve body; The second water-blocking component is connected to the first water-blocking component or the valve body; The pressure relief valve has a first position and a second position. In the first position, the axis of the pressure relief valve has a first angle with the horizontal plane. The first water-blocking element is used to stop water from seeping in from the gap between the air curtain and the valve body. In the second position, the axis of the pressure relief valve has a second angle with the horizontal plane, and the second water baffle is used to stop water from seeping in from the gap between the air curtain and the valve body. The first angle is different from the second angle.

[0005] In the above technical solution, the first water-blocking component can stop water from seeping into the vehicle interior when the pressure relief valve is in the first position, preventing water from entering the vehicle interior. Similarly, the second water-blocking component can stop water from seeping into the vehicle interior when the pressure relief valve is in the second position, thus meeting the waterproofing requirements of the pressure relief valve in different scenarios. This effectively prevents residual water from seeping into the vehicle interior, which could lead to mold growth on the interior, short circuits in electrical components, and water dripping from the lower part of the interior panels, affecting user experience. This allows the pressure relief valve to be applied to the tailgate or hatchback of the vehicle, thereby increasing the vehicle's wading depth and meeting its wading requirements.

[0006] In some possible implementations, the pressure relief valve includes a shut-off state in which the air curtain extends in a first direction, the first water-blocking member extends in a second direction, the angle between the first direction and the second direction is set as a third angle, the third angle being an acute angle, the second water-blocking member extends in a third direction, and the angle between the first direction and the third direction is set as a fourth angle, the fourth angle being a right angle or an obtuse angle.

[0007] This design allows the first and second water-blocking components to effectively stop the water flow.

[0008] In some possible implementations, both the first and second water-blocking members are plate-shaped, the second water-blocking member is angled relative to the first water-blocking member, and the end of the second water-blocking member away from the first water-blocking member faces the air curtain and extends in the third direction.

[0009] This configuration allows the first and second water-blocking components to respectively provide a stopping effect, thus meeting the water-blocking requirements of the pressure relief valve in both the first and second positions.

[0010] In some possible implementations, the length of the second water-blocking component in the third direction is set to 3mm-6mm.

[0011] This design satisfies both the water-blocking requirement and the small-size requirement, allowing the structure of the second water-blocking component to be made smaller without affecting the overall function of the pressure relief valve.

[0012] In some possible implementations, the second water-blocking member is connected to the first water-blocking member so that a receiving space is formed between the second water-blocking member and the first water-blocking member, the receiving space being used to accommodate water seeping in from the gap between the air curtain and the valve body.

[0013] With this configuration, when the pressure relief valve is in the second position, it can simultaneously block water, thus meeting the water blocking requirements.

[0014] In some possible implementations, the valve body is provided with an air inlet and an air outlet, a first end of the air curtain is rotatably connected to one side of the valve body, and a second end of the air curtain overlaps with the other side of the valve body, so that the air curtain can connect or disconnect the air inlet and the air outlet of the valve body by rotation. The first water-blocking component and the second water-blocking component are located near the second end of the air curtain, and the first water-blocking component and the second water-blocking component are disposed at the air inlet end of the valve body.

[0015] This design allows for targeted blocking, eliminating the need for excessively large sizes in the first and second water-blocking components, thus ensuring proper pressure relief and venting.

[0016] In some possible implementations, the valve body includes an annular frame and a support member, the annular frame enclosing a channel, the support member being disposed within the channel and connected to the annular frame, an air curtain being connected to the support member, the air curtain being used to open or close the channel, and both the first water-blocking member and the second water-blocking member being connected to the support member.

[0017] This design facilitates connection to the vehicle body and allows for coordination with the curtain airbags to either open or close the circuit.

[0018] In some possible implementations, there are multiple support members, which are arranged in parallel with spacing between them, and an air curtain is provided between every two adjacent support members. In this configuration, a first end of one of the air curtains is rotatably connected to one of the adjacent support members, and a second end of one of the air curtains overlaps with another adjacent support member.

[0019] This design allows for a reduction in the size of individual air curtains, thus ensuring the pressure relief and exhaust function.

[0020] In some possible implementations, the pressure relief valve further includes a seal connected to the valve body for pressing against the vehicle body.

[0021] This design enhances the seal between the valve body and the vehicle body, preventing water from seeping in through the gap and ensuring waterproofing.

[0022] A second aspect of this disclosure also provides a vehicle including the aforementioned pressure relief valve.

[0023] In some possible implementations, the vehicle includes a hatchback door with a mounting port to which the pressure relief valve is connected.

[0024] By setting it up in this way, the height of the pressure relief valve is increased, which can increase the vehicle's wading depth and buoyancy, break through the limitations of the vehicle's wading depth and buoyancy, and improve the vehicle's water environment passability.

[0025] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0034] 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.

[0035] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are generally defined by the orientation of the accompanying drawings, and "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] 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.

[0037] The pressure relief valve is an important component used to balance the air pressure inside and outside the vehicle, affecting the user experience, such as when the doors close. In actual use, vehicles are often placed in water-related scenarios, such as car washes or rain, so the pressure relief valve needs to have a certain water-blocking performance.

[0038] The water-blocking structure of the pressure relief valve in related technologies is mainly used to prevent water from entering the dry areas of the vehicle interior during car washing or rain. However, if the angle of the pressure relief valve changes, residual water may seep in, affecting the vehicle interior or related components. Specifically, when the pressure relief valve is located on the tailgate, its angle changes when the tailgate is opened. This change in the water-blocking angle means that residual water cannot be blocked, allowing it to seep into the vehicle interior. This can lead to mold growth on the interior trim, short circuits in electrical components, and water dripping from the underside of interior panels, affecting the user experience.

[0039] Therefore, such as Figures 1-7 As shown, one aspect of this disclosure provides a pressure relief valve, including a valve body 1, an air curtain 2, a first water-blocking component 3, and a second water-blocking component 4.

[0040] Air curtain 2 is rotatably connected to valve body 1, first water-blocking component 3 is connected to valve body 1, and second water-blocking component 4 is connected to either first water-blocking component 3 or valve body 1. The first water-blocking component 3 and the second water-blocking component 4 are used to generate a water-blocking effect.

[0041] The pressure relief valve has a first position and a second position. In the first position, the axis of the pressure relief valve is at a first angle 5 with the horizontal plane. The first water-blocking element 3 is used to block water from seeping in from the gap between the air curtain 2 and the valve body 1.

[0042] In the second position, the axis of the pressure relief valve is at a second angle 6 to the horizontal plane. The cooperation of the first water-blocking component 3 and the second water-blocking component 4 is used to stop water from seeping in from the gap between the air curtain 2 and the valve body 1. The first angle 5 is different from the second angle 6. It can be understood that the difference between the first angle 5 and the second angle 6 makes the inclination degree of the pressure relief valve different in the first position and the second position, thus requiring different water-blocking angles.

[0043] In the above technical solution, the first water-blocking component 3, when the pressure relief valve is in the first position, can stop water seeping into the vehicle through the gap between the air curtain 2 and the valve body 1, preventing water from entering the vehicle interior. Similarly, the second water-blocking component 4, when the pressure relief valve is in the second position, can stop water seeping into the vehicle interior through the gap between the air curtain 2 and the valve body 1, preventing water from entering the vehicle interior. This satisfies the waterproofing requirements of the pressure relief valve in different scenarios, effectively preventing residual water from seeping into the vehicle interior, which could lead to mold growth on the interior trim, short circuits in electrical components, and water dripping from the lower part of the interior trim panels, affecting user experience. This allows the pressure relief valve to be applied to the tailgate or hatchback of the vehicle, thereby increasing the vehicle's wading depth and meeting its wading requirements. It should be noted that when the pressure relief valve is in the second position, the second water-blocking component 4 can stop the water flow, or the first water-blocking component 3 and the second water-blocking component 4 can work together to achieve the same effect.

[0044] Optionally, in one embodiment of this disclosure, the pressure relief valve includes a shut-off state. In the shut-off state, the air curtain 2 extends in a first direction, the first water-blocking member 3 extends in a second direction, and the angle between the first and second directions is set as a third angle 7, which is an acute angle. The second water-blocking member 4 extends in a third direction, and the angle between the first and third directions is set as a fourth angle 8, which is a right angle or an obtuse angle. This arrangement facilitates the first and second water-blocking members 3 and 4 in stopping the water flow.

[0045] In this context, the "cut-off state" refers to the pressure relief valve not being open, and no air is released. The air curtain 2 seals the valve body 1. By setting the three angles to acute angles, in the cut-off state, the first water-blocking component 3 and the air curtain 2 are roughly in the same direction. Therefore, the first water-blocking component 3 is directly opposite the gap between the air curtain 2 and the valve body 1, thus directly preventing water seepage. By setting the fourth angle 8 to a right angle or obtuse angle, when the pressure relief valve changes position (i.e., to the second position), the second water-blocking component 4 then provides a stopping effect. It can be understood that in the first position, the air curtain 2 is positioned vertically, and the first water-blocking component 3 is also roughly vertically positioned, providing a stopping effect. In the second position, the air curtain 2 is not vertically positioned, and the first water-blocking component 3 is not vertically positioned either, but the second water-blocking component 4 is roughly vertically positioned, providing a stopping effect.

[0046] It is understandable that the pressure relief valve also includes a conducting state, which means that the air curtain 2 does not close the valve body 1. At this time, the air curtain 2 does not block the air flow and can realize pressure relief and exhaust.

[0047] Optionally, in one embodiment of this disclosure, both the first water-blocking member 3 and the second water-blocking member 4 are plate-shaped. The second water-blocking member 4 is angled relative to the first water-blocking member 3, with the end of the second water-blocking member 4 away from the first water-blocking member 3 facing the air curtain 2 and extending in a third direction. This arrangement allows the first water-blocking member 3 and the second water-blocking member 4 to respectively provide a blocking effect, satisfying the water-blocking requirements of the pressure relief valve in the first and second positions. It is understood that the angled arrangement of the first water-blocking member 3 and the second water-blocking member 4 facilitates setting the third angle 7 as an acute angle, and the angled extension of the second water-blocking member 4 away from the first water-blocking member 3 towards the air curtain 2 and in a third direction facilitates setting the fourth angle 8 as a right angle or an obtuse angle.

[0048] In some examples, the length of the second water-blocking component 4 in the third direction is set to 3mm-6mm. This setting satisfies both the water-blocking requirement and the small size requirement, allowing the structure of the second water-blocking component 4 to be relatively small, without affecting the overall function of the pressure relief valve, without excessively affecting the air intake area, without causing an increase in the size of the pressure relief valve, without affecting the space arrangement requirements of the pressure relief valve, and avoiding conflicts with other parts.

[0049] Alternatively, in another embodiment of this disclosure, the first water-blocking member 3 and the second water-blocking member 4 may be a semi-shell with a cavity capable of accommodating water, thereby creating a water-blocking effect.

[0050] Optionally, in one embodiment of this disclosure, the second water-blocking component 4 is connected to the first water-blocking component 3, forming a receiving space between them. This receiving space is used to accommodate water that seeps in from the gap between the air curtain 2 and the valve body 1. The connection between the second water-blocking component 4 and the first water-blocking component 3 allows them to cooperate, enabling them to block water together when the pressure relief valve is in the second position, thus meeting the water-blocking requirement. The blocked water is contained within the receiving space, ensuring the water-blocking effect and preventing water seepage.

[0051] It is understandable that one end of the first water-blocking component 3 is close to the air curtain 2, and the second water-blocking component 4 is connected to the end of the first water-blocking component 3 away from the air curtain 2. The first water-blocking component 3 plays the main role of blocking water, while the second water-blocking component 4 plays a role of blocking water when the pressure relief valve is in the second position. When the pressure relief valve is in the second position, the first water-blocking component 3 can also play a partial role of blocking water, so that the first water-blocking component 3 and the second water-blocking component 4 can work together to play a blocking role, and the accommodating space is used to temporarily accommodate the blocked water.

[0052] Alternatively, in another embodiment of this disclosure, the first water-blocking component 3 and the second water-blocking component 4 are respectively connected to the valve body 1. That is, the first water-blocking component 3 and the second water-blocking component 4 may not be connected. The first water-blocking component 3 and the second water-blocking component 4 respectively generate water-blocking function to adapt to the situation where the pressure relief valve is in the first position and the second position.

[0053] Alternatively, in another embodiment of this disclosure, the first water-blocking component 3 is connected to the valve body 1, and the second water-blocking component 4 can be partially connected to the valve body 1 and partially connected to the first water-blocking component 3. The first water-blocking component 3 and the second water-blocking component 4 can either individually produce a water-blocking effect or work together to produce a water-blocking effect.

[0054] Optionally, in one embodiment of this disclosure, the valve body 1 is provided with an inlet end and an outlet end. A first end of an air curtain 2 is rotatably connected to one side of the valve body 1, and a second end of the air curtain 2 overlaps with the other side of the valve body 1, so that the air curtain 2 can connect or disconnect the inlet end and the outlet end of the valve body 1 by rotation. This arrangement facilitates connecting or disconnecting the inlet end and the outlet end of the valve body 1, allowing for pressure relief and exhaust when needed. It is understood that when it is necessary to connect the inlet end and the outlet end of the valve body 1, the air curtain 2 rotates until its second end separates from the valve body 1, at which point pressure relief and exhaust can occur. When it is necessary to disconnect the inlet end and the outlet end of the valve body 1, the air curtain 2 rotates until its second end overlaps with the valve body 1, at which point pressure relief and exhaust are not performed.

[0055] The first water-blocking component 3 and the second water-blocking component 4 are located near the second end of the air curtain 2. Therefore, the first water-blocking component 3 and the second water-blocking component 4 primarily prevent water from seeping in through the gap between the second end of the air curtain 2 and the valve body 1. This is because the second end of the air curtain 2 needs to be connected to or separated from the valve body 1, creating a gap that allows water to seep in. Therefore, the first water-blocking component 3 and the second water-blocking component 4 are located near the second end of the air curtain 2, providing a targeted stopping effect. The dimensions of the first water-blocking component 3 and the second water-blocking component 4 do not need to be excessively large, thus not affecting pressure relief and air venting.

[0056] The first water-blocking component 3 and the second water-blocking component 4 are located at the air inlet end of the valve body 1. It can be understood that the air inlet end of the valve body 1 faces the inside of the vehicle, and the pressure relief and exhaust are mainly caused by the exhaust of gas from inside the vehicle through the valve body 1. Therefore, the first water-blocking component 3 and the second water-blocking component 4 are primarily used to prevent water from seeping from the air outlet end of the valve body 1 into the air inlet end of the valve body 1. Thus, the first water-blocking component 3 and the second water-blocking component 4 can effectively provide a blocking effect at the air inlet end of the valve body 1.

[0057] Optionally, in one embodiment of this disclosure, the valve body 1 includes an annular frame 11 and a support member 12. The annular frame 11 encloses to form a channel, the support member 12 is disposed in the channel and connected to the annular frame 11, the air curtain 2 is connected to the support member 12, and the air curtain 2 is used to open or close the channel. The first water-blocking member 3 and the second water-blocking member 4 are both connected to the support member 12.

[0058] The channel is used to allow airflow and achieve exhaust pressure relief. It can be understood that the space enclosed by the annular frame 11 is the inner space of the annular frame 11, which is the channel. The annular frame 11 can create an enclosing effect in the radial direction, thereby cooperating with the air curtain 2 to create a sealing effect, which can facilitate the air curtain 2 to cut off the channel. In addition, the annular frame 11 can facilitate the connection with the vehicle body, ensuring the connection area and the connection strength.

[0059] The support member 12 is used to provide installation and support for the air curtain 2. In addition, the support member 12 is used to fix the first water-blocking member 3 and the second water-blocking member 4, so that the first water-blocking member 3 and the second water-blocking member 4 are close to the second end of the air curtain 2, so that the first water-blocking member 3 and the second water-blocking member 4 can stop the water from seeping in from the gap between the air curtain 2 and the support member 12, thus producing a waterproof effect.

[0060] Optionally, in one embodiment of this disclosure, there are multiple support members 12, which are arranged in parallel at intervals, with an air curtain 2 between each pair of adjacent support members 12. The air curtain 2 between each pair of adjacent support members 12 is used to enclose the space between the two adjacent support members 12, so as to provide a cut-off effect when pressure relief and exhaust are not required. It can be understood that by setting multiple support members 12 and arranging them side by side, the size of a single air curtain 2 can be reduced, thereby facilitating the rotation of the air curtain 2 and reducing the area of ​​the air curtain 2 that bears pressure, avoiding the need for excessive pressure to push the air curtain 2 open, thus ensuring the pressure relief and exhaust function.

[0061] In this configuration, the first end of one air curtain 2 is rotatably connected to one of the adjacent support members 12, and the second end of one air curtain 2 overlaps with another adjacent support member 12. It is understood that the two ends of the multiple support members 12 are respectively connected to the inner wall of the annular frame 11, and the multiple support members 12 are placed horizontally within the channel. The multiple support members 12 can support different air curtains 2 respectively, ensuring the rotatable connection and overlapping effect of the air curtains 2.

[0062] Among them, multiple spaced partitions can be provided between two adjacent support members 12, and the partitions can provide support for the air curtain.

[0063] Optionally, in one embodiment of this disclosure, the pressure relief valve further includes a seal 9 connected to the valve body 1 and used for pressing against the vehicle body. The seal 9 enhances the sealing effect between the valve body 1 and the vehicle body, preventing water from seeping in through the gap between the valve body 1 and the vehicle body, thus ensuring waterproof performance. In some examples, the seal 9 may be a soft lip made of rubber, which can be pressed against the vehicle body to ensure tightness. The seal 9 is annular, extending along the edge of the annular frame 11 to form an annular seal.

[0064] A second aspect of this disclosure also provides a vehicle including the aforementioned pressure relief valve.

[0065] Optionally, in one embodiment of this disclosure, the pressure relief valve can be installed on the vehicle body or on the vehicle tailgate.

[0066] Optionally, in one embodiment of this disclosure, the vehicle includes a hatchback door with a mounting opening, and a pressure relief valve is connected to the mounting opening. Since the hatchback door's angle changes when opened or closed, this pressure relief valve can effectively adapt to the waterproofing required by these angle changes. Furthermore, placing the pressure relief valve on the hatchback door increases its height, thereby increasing the vehicle's wading depth and buoyancy, overcoming the limitations of the vehicle's overall wading depth and buoyancy, and improving the vehicle's overall water handling capabilities.

[0067] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0069] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
