Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically to a pressure relief valve assembly and a vehicle. Background Technology

[0002] Vehicles are generally equipped with pressure relief valves, which are used to balance the pressure difference between the inside and outside of the vehicle to improve driving comfort. In traditional vehicles, the pressure relief valves are typically located below the outer side panels on both sides of the rear of the vehicle. The height of the bottom of the pressure relief valve from the ground determines the vehicle's wading depth. Wading depth is an important indicator; a greater wading depth improves vehicle safety. In traditional vehicles, increasing the wading depth would require moving the entire pressure relief valve upwards. However, moving the pressure relief valve upwards necessitates altering the vehicle's structure, potentially resulting in changes to the car's appearance. Utility Model Content

[0003] In view of this, this application provides a pressure relief valve assembly and electronic device to improve the wading depth of a vehicle.

[0004] The first aspect of this application provides a pressure relief valve assembly, including a valve body and a valve cover. The valve body is provided with a pressure relief channel, and the valve cover is connected to the valve body. The valve cover and the valve body enclose a receiving cavity for storing liquid, and the receiving cavity is in communication with the pressure relief channel.

[0005] In this application, the pressure relief valve assembly can not only relieve pressure in the passenger compartment of the vehicle, but also allow some liquids such as road sewage or rainwater from outside the vehicle to flow into the receiving cavity through the pressure relief channel when the water level outside the vehicle is higher than the bottom of the pressure relief channel. This prevents external liquids from entering the passenger compartment, ensuring the vehicle's driving safety in wading conditions and increasing the vehicle's wading depth. Furthermore, in this embodiment, the wading depth is increased by installing a valve cover on the valve body. This method is simple in structure and does not require moving the entire pressure relief valve assembly onto the vehicle body. Therefore, the pressure relief valve assembly of this embodiment does not require additional modifications to the vehicle body structure, increasing its applicability and versatility, and reducing vehicle manufacturing costs.

[0006] In one possible design, the valve cover includes a baffle, a bottom plate, and side plates connected to each other. Along the width direction of the pressure relief valve assembly, the baffle is located on one side of the valve body. Along the height direction of the pressure relief valve assembly, the bottom plate is disposed at the bottom end of the baffle. Along the length direction of the pressure relief valve assembly, the side plates are disposed on opposite sides of the baffle. The side plates, the baffle, the bottom plate, and the valve body enclose the receiving cavity.

[0007] The valve cover structure is simple and stable, and easy to assemble. The side plates, baffles and bottom plates can form a receiving cavity with the valve body, so that when the water level outside the vehicle is higher than the bottom of the pressure relief channel on the valve body, the liquid flowing in through the pressure relief channel can be stored in the receiving cavity, thereby improving the safe wading depth of the vehicle.

[0008] In one possible design, along the height direction of the pressure relief valve assembly, the bottom end of the valve cover is lower than the bottom end of the pressure relief passage.

[0009] This structure allows liquid flowing in through the bottom of the pressure relief channel to enter the containment cavity, further preventing external liquid from entering the vehicle's passenger compartment and improving the vehicle's driving safety under wading conditions.

[0010] In one possible design, the valve cover further includes a surrounding plate connected to the side plate and disposed opposite to the baffle. The side plate, the baffle, the bottom plate, the surrounding plate, and the valve body together form the receiving cavity.

[0011] The valve cover structure is simple, and the enclosure can further increase the storage capacity of the cavity, which is conducive to further increasing the wading depth of the vehicle and meeting the wading requirements of the vehicle.

[0012] In one possible design, along the height direction of the pressure relief valve assembly, the top of the valve cover is flush with the top of the pressure relief channel, or the top of the valve cover is higher than the top of the pressure relief channel.

[0013] This structure allows the valve cover to block the pressure relief channel, so that all the liquid flowing in through the pressure relief channel can flow into the receiving cavity. It can also further increase the storage capacity of the receiving cavity, prevent liquid from overflowing from the receiving cavity, and further improve the driving safety of the vehicle in water-wading conditions.

[0014] In one possible design, an opening is provided at the top of the valve cover along the height direction of the pressure relief valve assembly.

[0015] The containment chamber can be connected to the passenger compartment inside the vehicle through an opening, thus sequentially connecting the passenger compartment, the containment chamber, and the pressure relief channel. This allows air in the passenger compartment to flow out sequentially through the containment chamber and the pressure relief channel when the air pressure exceeds the critical pressure value of the pressure relief valve assembly, achieving a pressure relief effect. Furthermore, the opening's location at the top of the valve cover increases the containment chamber's storage capacity, which is beneficial for further improving the vehicle's wading depth.

[0016] In one possible design, the valve cover is detachably connected to the valve body.

[0017] This structure facilitates the assembly and disassembly of the pressure relief valve assembly. During assembly, the valve body can be installed on the vehicle body first, followed by the valve cover, reducing the space requirements for the pressure relief valve assembly and simplifying its installation on the vehicle body. During disassembly, the valve cover can be removed first, followed by the valve body, facilitating the replacement of the pressure relief valve assembly.

[0018] In one possible design, a first seal is provided between the valve cover and the valve body.

[0019] The first seal can improve the sealing at the connection between the valve cover and the valve body, thereby preventing liquid in the containment cavity from flowing into the passenger compartment of the vehicle, and further improving the vehicle's driving safety under wading conditions.

[0020] In one possible design, the valve cover is integrally formed with the valve body, thereby facilitating the fabrication of the pressure relief valve assembly, improving the fabrication efficiency of the pressure relief valve assembly, and reducing the fabrication cost of the pressure relief valve assembly.

[0021] In one possible design, the pressure relief valve assembly further includes a valve plate that blocks the side of the pressure relief passage away from the valve cover.

[0022] When the air pressure in the vehicle's passenger compartment is greater than or equal to the critical pressure of the pressure relief valve assembly, the valve plate opens the pressure relief passage to maintain stable air pressure in the passenger compartment, improving user comfort during driving. When the air pressure in the passenger compartment is less than the critical pressure of the pressure relief valve assembly, the valve plate seals the pressure relief passage under its own weight, improving the sealing effect of the passenger compartment. The valve plate is positioned on the side of the pressure relief passage away from the valve cover, allowing it to be located on the outside of the vehicle body while the valve cover is located on the inside. This avoids interference between the valve plate and the valve cover, facilitating the opening or sealing of the pressure relief passage and ensuring the pressure relief effect of the pressure relief valve assembly. It also reduces the size of the pressure relief valve assembly located outside the vehicle body, preventing interference with other external components such as the rear bumper, further facilitating the installation of the pressure relief valve assembly.

[0023] In one possible design, the valve body is provided with a snap-fit ​​protrusion, and the valve plate is provided with a snap-fit ​​groove, wherein the snap-fit ​​protrusion snaps into the snap-fit ​​groove.

[0024] The valve body and valve plate are engaged by a snap-fit ​​protrusion and a snap-fit ​​groove. This structure is simple and easy to assemble, which can further reduce the structural complexity of the pressure relief valve assembly and improve the assembly efficiency of the pressure relief valve assembly.

[0025] In one possible design, the pressure relief channel includes one or more pressure relief holes.

[0026] This structure ensures the pressure relief effect of the pressure relief valve assembly while also improving the structural strength of the valve body, reducing the risk of damage to the valve body from external forces, extending the service life of the pressure relief valve assembly, and saving operating costs.

[0027] In one possible design, a limiting rib is provided in the pressure relief hole, and the limiting rib abuts against the valve plate.

[0028] When the valve plate blocks the pressure relief hole, the limiting rib can abut against the valve plate, thereby providing limiting support and improving the structural strength of the valve plate when blocking the pressure relief hole. This prevents the valve plate from curling and deforming, and extends its service life. Furthermore, the limiting rib further enhances the overall structural strength of the valve body, thus further extending its service life.

[0029] In one possible design, the pressure relief valve assembly further includes a second seal fitted around the outer periphery of the valve body; the second seal is used for a sealing connection with the vehicle body.

[0030] After the valve body is engaged with the vehicle body, a second seal can be placed between the buckle and the vehicle body to improve the sealing at the connection between the valve body and the vehicle body, thereby further improving the vehicle's driving safety under water wading conditions.

[0031] A second aspect of this application provides a vehicle comprising a body and a pressure relief valve assembly as described in any of the above embodiments, the pressure relief valve assembly being mounted on the body. Since the pressure relief valve assembly has the aforementioned technical effects, a vehicle including this pressure relief valve assembly should also have corresponding technical effects, which will not be elaborated further here.

[0032] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0057] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0058] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0059] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] Vehicles are generally equipped with pressure relief valves, which are used to balance the pressure difference between the inside and outside of the vehicle to improve driving comfort. In traditional vehicles, the pressure relief valves are typically located below the outer side panels on both sides of the rear of the vehicle. The height of the bottom of the pressure relief valve from the ground determines the vehicle's wading depth. Wading depth is an important indicator; a greater wading depth improves vehicle safety. In traditional vehicles, increasing the wading depth would require moving the entire pressure relief valve upwards. However, moving the pressure relief valve upwards necessitates altering the vehicle's structure, potentially resulting in changes to the car's appearance.

[0062] In view of this, embodiments of this application provide a pressure relief valve assembly that can be applied to vehicles and other vehicles with wading conditions to improve the wading depth of the vehicle.

[0063] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle provided in an embodiment of this application.

[0064] like Figure 1As shown, the vehicle 100 includes a body 20, and a pressure relief valve assembly 10 is mounted on the body 20. Specifically, the pressure relief valve assembly 10 is mounted on the rear panel of the body 20. The pressure relief valve assembly 10 can be fixed to the body 20 by means of snap-fit ​​or other methods.

[0065] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a pressure relief valve assembly provided in an embodiment of this application. The pressure relief valve assembly 10 includes a length direction X, a width direction Y, and a height direction Z.

[0066] like Figure 2 As shown, the pressure relief valve assembly 10 includes a valve body 1 and a valve cover 2.

[0067] The valve body 1 is provided with a pressure relief channel 11, which allows air in the passenger compartment of the vehicle to circulate to the external environment, balancing the pressure difference between the inside and outside of the vehicle. The pressure relief channel 11 can extend through the valve body 1 along the width direction Y of the pressure relief valve assembly 10, or it can extend through the valve body 1 along other directions that form an angle with the height direction Z of the pressure relief valve assembly 10. The specific configuration of the pressure relief channel 11 can be determined according to actual needs, as long as it extends through the valve body 1.

[0068] The valve cover 2 is connected to the valve body 1, and the valve cover 2 and the valve body 1 enclose a receiving cavity 3 for storing liquid. The receiving cavity 3 is connected to the pressure relief channel 11.

[0069] In this embodiment, as Figure 2 As shown, the pressure relief valve assembly 10 of this structure can not only relieve pressure in the passenger compartment inside the vehicle, but also allow some liquids such as road sewage or rainwater outside the vehicle to flow into the receiving cavity 3 through the pressure relief channel 11 when the water level outside the vehicle is higher than the bottom of the pressure relief channel 11. This prevents liquids outside the vehicle from entering the passenger compartment, ensuring the vehicle's driving safety under wading conditions and increasing the vehicle's wading depth. In addition, in this embodiment, the wading depth of the vehicle is increased by installing a valve cover 2 on the valve body 1. The structure is simple and does not require moving the pressure relief valve assembly 10 as a whole on the vehicle body. Therefore, the pressure relief valve assembly 10 of this embodiment does not require additional modifications to the vehicle body structure, improving the applicability of the pressure relief valve assembly 10, having high versatility, and reducing the vehicle's manufacturing cost.

[0070] like Figure 2 As shown, in one specific embodiment, the valve cover 2 can be integrally formed with the valve body 1, thereby facilitating the fabrication of the pressure relief valve assembly 10, improving the fabrication efficiency of the pressure relief valve assembly 10, and reducing the fabrication cost of the pressure relief valve assembly 10.

[0071] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the pressure relief valve assembly provided in this application embodiment in another specific embodiment.

[0072] like Figure 3 As shown, in another specific embodiment, the valve cover 2 can also be manufactured separately from the valve body 1, allowing the valve cover 2 and valve body 1 to be detachably connected, thereby facilitating the assembly and disassembly of the pressure relief valve assembly 10. During assembly, the valve body 1 can be installed on the vehicle body first, and then the valve cover 2 can be installed on the valve body 1, reducing the space requirements for the pressure relief valve assembly 10 during assembly and facilitating the assembly of the pressure relief valve assembly 10 with the vehicle body. During disassembly, the valve cover 2 can be removed first, and then the valve body 1 can be removed from the vehicle body, facilitating the replacement of the pressure relief valve assembly 10.

[0073] Furthermore, the valve cover 2 can be detachably connected to the valve body 1 by means of snap-fit, screw connection, etc., thereby reducing the structural complexity of the pressure relief valve assembly 10 and facilitating the connection between the valve cover 2 and the valve body 1.

[0074] When the valve cover 2 and the valve body 1 are detachably connected, a first sealing element (not shown in the figure) can be provided between the valve cover 2 and the valve body 1 to improve the sealing performance at the connection between the valve cover 2 and the valve body 1, thereby preventing the liquid in the containment cavity 3 from flowing into the passenger compartment of the vehicle and further improving the driving safety of the vehicle under water wading conditions.

[0075] Of course, in some other embodiments, the valve cover 2 can also be connected to the valve body 1 by bonding to improve the sealing of the cavity 3 and further reduce the structural complexity of the pressure relief valve assembly 10. The specific configuration can be made according to actual needs and is not limited here.

[0076] like Figure 3 As shown, a snap-fit ​​14 can be provided on the valve body 1, and the valve body 1 and the vehicle body can be snapped together by the snap-fit ​​14. The structure is simple and easy to implement, which can further reduce the structural complexity of the pressure relief valve assembly 10.

[0077] The number of clips 14 can be multiple, and these clips 14 can be spaced apart on the outer periphery of the valve body 1 to improve the connection stability between the valve body 1 and the vehicle body. Specifically, the multiple clips 14 can be spaced apart at the top and bottom of the valve body 1 along the height direction Z, such as... Figure 3 In the specific embodiment shown, along the height direction Z of the pressure relief valve assembly 10, three buckles can be provided at intervals at the top and bottom of the valve body 1, so as to ensure the connection stability between the valve body 1 and the vehicle body, while avoiding interference between the buckles 14 and the valve cover 2, thereby facilitating the connection between the valve cover 2 and the valve body 1.

[0078] Furthermore, such as Figure 3As shown, the pressure relief valve assembly 10 may also include a second seal 5, which is sleeved on the outer periphery of the valve body 1 and is used for sealing connection with the body 20 of the vehicle 100.

[0079] In this embodiment, after the valve body 1 is engaged with the vehicle body, the second sealing element 5 can be disposed between the buckle 14 and the vehicle body to improve the sealing performance at the connection between the valve body 1 and the vehicle body, thereby further improving the driving safety of the vehicle under water wading conditions.

[0080] like Figure 3 As shown, in one specific embodiment, the valve cover 2 includes a baffle 21, a base plate 22, and a side plate 23 connected to each other. The baffle 21 is located on one side of the valve body 1 along the width direction Y of the pressure relief valve assembly 10. The base plate 22 is disposed at the bottom end of the baffle 21 along the height direction Z of the pressure relief valve assembly 10. The side plates 23 are disposed on opposite sides of the baffle 21 along the length direction X of the pressure relief valve assembly 10.

[0081] Please refer to the following at the same time Figure 4 and Figure 5 , Figure 4 This is a front view of a pressure relief valve assembly provided in an embodiment of this application, in one specific embodiment. Figure 5 for Figure 4 A cross-sectional view along the AA direction.

[0082] like Figure 5 As shown, the side plate 23, baffle 21, bottom plate 22 and valve body 1 surround and form a receiving cavity 3.

[0083] In this embodiment, the valve cover 2 has a simple and stable structure that is easy to assemble. The side plate 23, baffle 21 and bottom plate 22 can form a receiving cavity 3 with the valve body 1, so that when the water level outside the vehicle is higher than the bottom of the pressure relief channel 11 on the valve body 1, the liquid flowing in through the pressure relief channel 11 can be stored in the receiving cavity 3, thereby improving the safe wading depth of the vehicle.

[0084] Among them, such as Figure 5 As shown, along the height direction Z of the pressure relief valve assembly 10, the bottom end of the valve cover 2 is lower than the bottom end of the pressure relief channel 11, that is, the base plate 22 is set below the pressure relief channel 11, so that the liquid flowing in through the bottom end of the pressure relief channel 11 can enter the receiving cavity 3, further preventing liquid outside the vehicle from entering the passenger compartment inside the vehicle, and further improving the driving safety of the vehicle under water conditions.

[0085] In addition, the degree of the valve cover 2 can be adjusted according to actual needs, that is, the dimensions of the side plate 23, baffle 21, and bottom plate 22 in the length direction X, width direction Y, and / or height direction Z can be adjusted to meet the vehicle's wading depth target. For example, the wading depth of the vehicle can be increased by 50mm to 100mm or more by adjusting the height of the valve cover 2. The specific setting can be made according to actual needs and is not limited here.

[0086] Furthermore, along the height direction of the pressure relief valve assembly 10, the tops of the side plate 23, baffle 21, and bottom plate 22 are flush to increase the storage capacity of the receiving cavity 3, prevent liquid from overflowing from the receiving cavity 3, and further improve the driving safety of the vehicle under water wading conditions.

[0087] For example, along the height direction Z of the pressure relief valve assembly 10, the top of the valve cover 2 is lower than the top of the pressure relief channel 11. This can reduce the volume of the valve cover 2 while meeting the vehicle's wading depth target, thereby facilitating the miniaturization of the pressure relief valve assembly 10 and making the assembly of the pressure relief valve assembly 10 easier.

[0088] For example, such as Figure 5 As shown, along the height direction Z of the pressure relief valve assembly 10, the top of the valve cover 2 is roughly flush with the top of the pressure relief channel 11, so that the valve cover 2 can almost completely cover the pressure relief channel 11, so that the liquid flowing in through the pressure relief channel 11 can all flow into the receiving cavity 3, which can further increase the storage capacity of the receiving cavity 3, prevent the liquid from overflowing from the receiving cavity 3, and further improve the driving safety of the vehicle under water conditions.

[0089] For example, please refer to Figure 6 , Figure 6 This is a cross-sectional view of the pressure relief valve assembly provided in an embodiment of this application in another specific embodiment. (See attached image.) Figure 6 As shown, the top of the valve cover 2 is higher than the top of the pressure relief channel 11, which can further increase the storage capacity of the receiving cavity 3 and further increase the wading depth of the vehicle to meet the wading requirements of the vehicle.

[0090] like Figure 6 As shown, in one specific embodiment, the valve cover 2 may further include a surrounding plate 24, which is connected to the side plate 23 and is disposed opposite to the baffle 21. The side plate 23, the baffle 21, the bottom plate 22, the surrounding plate 24 and the valve body 1 surround to form a receiving cavity 3.

[0091] In this embodiment, as Figure 6 As shown, the valve cover 2 has a simple structure, and the enclosure 24 can further increase the storage capacity of the accommodating cavity 3, which is conducive to further increasing the wading depth of the vehicle and meeting the wading requirements of the vehicle.

[0092] The tops of the enclosure 24, side panels 23, baffles 21, and bottom plate 22 are flush to increase the storage capacity of the receiving cavity 3, prevent liquid from overflowing from the receiving cavity 3, and further improve the driving safety of the vehicle in wading conditions.

[0093] Of course, the dimensions of the above-mentioned enclosure 24, side plate 23, baffle 21 and bottom plate 22 in the height direction Z can also be different. That is, the tops of the above-mentioned enclosure 24, side plate 23, baffle 21 and bottom plate 22 can be set unevenly to meet the installation space requirements of different pressure relief valve assemblies 10 and avoid interference between the pressure relief valve assembly 10 and other components. As long as the storage capacity of the accommodating cavity 3 can meet the vehicle's wading depth target, no restrictions are imposed here.

[0094] It should be noted that the top of the valve cover 2 refers to the lowest position of the top of the above-mentioned enclosure 24, side plate 23, baffle 21 and bottom plate 22 in the height direction Z.

[0095] Of course, in some other implementations, the valve cover 2 can also be hemispherical or other irregular shapes to further enhance the design freedom of the pressure relief valve assembly 10. The specific design can be set according to actual needs and is not limited here.

[0096] Furthermore, such as Figure 5 As shown, along the height direction Z of the pressure relief valve assembly 10, the top of the valve cover 2 may be provided with an opening 25.

[0097] In this embodiment, the receiving cavity 3 can be connected to the passenger compartment inside the vehicle through the opening 25, thereby connecting the passenger compartment, the receiving cavity 3, and the pressure relief channel 11 in sequence. When the air pressure in the passenger compartment exceeds the critical pressure value of the pressure relief valve assembly, the air in the passenger compartment can flow out sequentially through the receiving cavity 3 and the pressure relief channel 11, thus relieving pressure. Furthermore, the opening 25 is located at the top of the valve cover 2, which can increase the storage capacity of the receiving cavity 3, further improving the vehicle's wading depth.

[0098] Of course, in other embodiments, a top plate can also be provided on the top of the valve cover 2 along the height direction of the pressure relief valve assembly 10, and the opening 25 can be opened on the top plate to improve the structural stability of the receiving cavity 3. Alternatively, the opening 25 can also be provided on the side plate 23 or baffle 21 of the valve cover 25 to meet different vehicle requirements. The specific configuration can be made according to actual needs and is not limited here.

[0099] Please refer to Figure 7 , Figure 7 This is a partially exploded view of the pressure relief valve assembly provided in an embodiment of this application in another specific embodiment.

[0100] like Figure 7As shown, the pressure relief valve assembly 10 also includes a valve plate 4, which blocks the side of the pressure relief passage 11 away from the valve cover 2.

[0101] like Figure 7 As shown, when the air pressure in the passenger compartment is greater than or equal to the critical pressure of the pressure relief valve assembly 10, the valve plate 4 can open the pressure relief passage 11 to keep the air pressure in the passenger compartment stable and improve the comfort of the user during driving. When the air pressure in the passenger compartment is less than the critical pressure of the pressure relief valve assembly 10, the valve plate 4 can block the pressure relief passage 11 under its own weight to improve the sealing effect of the passenger compartment.

[0102] The valve plate 4 is located on the side of the pressure relief channel 11 away from the valve cover 2. This allows the valve plate 4 to be located on the outside of the vehicle body and the valve cover 2 to be located on the inside of the vehicle body. This avoids interference between the valve plate 4 and the valve cover 2, making it easier for the valve plate 4 to open or block the pressure relief channel 11 to ensure the pressure relief effect of the pressure relief valve assembly 10. It also reduces the volume of the pressure relief valve assembly 10 located outside the vehicle body, thereby avoiding interference between the pressure relief valve assembly 10 and other components installed on the outside of the vehicle body (such as the rear bumper), further facilitating the installation of the pressure relief valve assembly 10.

[0103] Specifically, the valve plate 4 can be made of flexible materials such as rubber, silicone, or silicone rubber. The specific design can be set according to actual needs, and no restrictions are imposed here.

[0104] Furthermore, such as Figure 7 As shown, the valve body 1 can be provided with a snap-fit ​​protrusion 13, and the valve plate 4 can be provided with a corresponding snap-fit ​​groove 41, so that the valve body 1 and the valve plate 4 can be snapped together through the snap-fit ​​protrusion 13 and the snap-fit ​​groove 41. This structure is simple and easy to assemble, which can further reduce the structural complexity of the pressure relief valve assembly 10 and improve the assembly efficiency of the pressure relief valve assembly 10.

[0105] In one specific embodiment, such as Figures 5-7 As shown, the pressure relief channel 11 includes one or more pressure relief holes 111, which can ensure the pressure relief effect of the pressure relief valve assembly 10, while also improving the structural strength of the valve body 1, reducing the risk of damage to the valve body 1 from external forces, increasing the service life of the pressure relief valve assembly 10, and saving operating costs.

[0106] Multiple pressure relief holes 111 can be arranged sequentially along the height direction Z and / or length direction X of the pressure relief valve assembly 10. The shape of the pressure relief holes 111 can be rectangular, trapezoidal, circular, etc., and can be set according to actual needs, without limitation here. Figure 7In the specific embodiment shown, the pressure relief channel 11 includes six pressure relief holes 111. The pressure relief holes 111 are rectangular in shape. The six pressure relief holes 111 are arranged along the height direction Z and length direction X of the pressure relief valve assembly 10 to facilitate the fabrication and formation of the pressure relief valve assembly 10 and ensure the pressure relief effect of the pressure relief valve assembly 10.

[0107] like Figure 4 and Figure 7 As shown, the number of valve plates 4 can be the same as the number of pressure relief holes 111. Each valve plate 4 can be connected above the corresponding pressure relief hole 111 so that the valve plate 4 can block or open the pressure relief hole 111 and ensure the pressure relief effect of the pressure relief valve assembly 10.

[0108] Furthermore, such as Figure 7 As shown, a limiting rib 12 can be provided in the pressure relief hole 111. When the valve plate 4 blocks the pressure relief hole 111, the limiting rib 12 can abut against the valve plate 4, thereby providing limiting support for the valve plate 4, improving the structural strength of the valve plate 4 when blocking the pressure relief hole 111, preventing the valve plate from curling and deforming, and extending the service life of the valve plate 4. In addition, the setting of the limiting rib 12 can further improve the overall structural strength of the valve body 1, thereby further extending the service life of the valve body 1.

[0109] Among them, such as Figure 7 As shown, the limiting rib 12 can be a plate-shaped, mesh-like, or other structure. The specific design can be customized according to actual needs to enhance the design freedom of the pressure relief valve assembly 10. No restrictions are imposed here.
