Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and in particular to a pressure relief valve and a vehicle. Background Technology

[0002] As part of the car's air venting system, the car's pressure relief valve is designed to release air to the outside when the pressure inside the car cabin is too high, in order to maintain the pressure balance between the inside and outside of the cabin. For example, when a user closes a door, the pressure inside the car cabin increases instantaneously. The pressure relief valve installed on the car body regulates the cabin pressure when the door is closed, thus improving the sound quality of the door closing.

[0003] However, during the research and development process, different sizes of pressure relief valves are developed because the cabin volumes of different vehicle classes are different. For example, large, medium and small sedans and SUVs have different cabin volumes, requiring the development of multiple pressure relief valves of different sizes. This makes it impossible to achieve the standardization of parts and results in high design and mold costs. Utility Model Content

[0038] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0039] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] This application provides a pressure relief valve, such as... Figures 1-8 As shown, the pressure relief valve 1 may include a plurality of valve bodies arranged side by side along a first direction. The plurality of valve bodies include a first valve body 10 and a second valve body 20, wherein the first valve body 10 is located at the beginning of the plurality of valve bodies along the first direction, and the second valve body 20 is located at the end of the plurality of valve bodies along the first direction. The first direction may be the length direction of the vehicle, the width direction of the vehicle, or the height direction of the vehicle.

[0041] The first valve body 10 includes a first frame portion 11 and a first pressure relief opening portion 12. The first frame portion 11 is located on the outer periphery of the first pressure relief opening portion 12. The second valve body 20 includes a second frame portion 21 and a second pressure relief opening portion 22. The second frame portion 21 is located on the outer periphery of the second pressure relief opening portion 22. The first pressure relief opening portion 12 and the second pressure relief opening portion 22 are arranged side by side. The first frame portion 11 is provided with a first connecting portion 111, and the second frame portion 21 is provided with a second connecting portion 211. Both the first connecting portion 111 and the second connecting portion 211 are used to connect with other valve bodies other than the valve body they are located in, so that multiple valve bodies are connected to form a combination.

[0042] In other words, the first connecting part 111 and the second connecting part 211 can be directly or indirectly connected. For example, when the pressure relief valve 1 only includes the first valve body 10 and the second valve body 20, the first connecting part 111 and the second connecting part 211 can be directly connected so that the first valve body 10 and the second valve body 20 are combined into an integral assembly. However, when the pressure relief valve 1 also includes a valve body disposed between the first valve body 10 and the second valve body 20 in addition to the first valve body 10 and the second valve body 20, the first connecting part 111 and the second connecting part 211 are respectively connected to the connecting parts of other valve bodies. In this case, the first connecting part 111 and the second connecting part 211 are indirectly connected, so that multiple valve bodies are combined into an integral assembly.

[0043] Furthermore, the first connecting part 111 is provided on the connecting surface of the first frame part 11 (i.e., the first connecting surface below), and the second connecting part 211 is provided on the connecting surface of the second frame part 20 (i.e., the second connecting surface below). At least a portion of the structure of the first connecting part 111 and the second connecting part 211 is formed as a connecting structure. The connecting structure can be a snap, a slot, a glue groove, a welding surface, a rivet hole, a screw hole, etc., as long as it can satisfy the fixed connection between the two hands. No specific restrictions are made here.

[0044] Furthermore, each valve body is provided with a blade 60. In other words, both the first valve body 10 and the second valve body 20 are provided with blades 60. The blades 60 of the first valve body 10 can be movably covered on the first pressure relief opening 12 to open or close the first pressure relief opening 12. Correspondingly, the blades 60 of the second valve body 20 can be movably covered on the second pressure relief opening 22 to open or close the second pressure relief opening 22.

[0045] In this embodiment, the pressure relief valve 1 is composed of multiple valve bodies. When developing different vehicle models, the pressure relief area of ​​the pressure relief valve can be adjusted by adding or removing valve bodies between the first valve body 10 and the second valve body 20 according to the pressure relief area requirements corresponding to the vehicle compartment volume of the vehicle model. This achieves the universality of the pressure relief valve 1, simplifies vehicle development costs, and shortens the development cycle. Furthermore, by reserving connecting portions (such as the first connecting portion 111 and the second connecting portion 211) on the frame portions of the first valve body 10 and the second valve body 20 (including the first frame portion 11 of the first valve body 10 and the second frame portion 21 of the second valve body 20), the assembly and connection between multiple valve bodies can be facilitated, which helps to improve assembly efficiency and makes the use of the pressure relief valve 1 more convenient.

[0046] In some embodiments, the plurality of valve bodies further includes an intermediate valve body 30, such as Figures 2-4 As shown, the intermediate valve body 30 includes a third frame portion 31 and a third pressure relief opening portion 32. The third frame portion 31 is located on the outer periphery of the third pressure relief opening portion 32. The intermediate valve body 30 is disposed between the first valve body 10 and the second valve body 20. The third pressure relief opening portion 32 is disposed side by side with the first pressure relief opening portion 12. When there are multiple intermediate valve bodies 30, at least the intermediate valve body 30 closest to the first valve body 10 is connected to the first connecting portion 111, and at least the intermediate valve body 30 closest to the second valve body 20 is connected to the second connecting portion 211. When there is only one intermediate valve body 30, the intermediate valve body 30 is connected to the first connecting portion 111 and the second connecting portion 211 on both sides along the first direction, respectively.

[0047] Furthermore, the intermediate valve body 30 is also provided with a blade 60, which can be movably covered by the third pressure relief opening 32.

[0048] In some embodiments, the pressure relief valve 1 includes at least one intermediate valve body 30, which is disposed between the first valve body 10 and the second valve body 20, enabling it to change the pressure relief area of ​​the pressure relief valve 1. Here, the number of intermediate valve bodies 30 can be 1, 2, 3...N, specifically determined according to the pressure relief area requirements of the pressure relief valve corresponding to the vehicle compartment volume of the vehicle model.

[0049] Furthermore, the number of intermediate valve bodies 30 is proportional to the vehicle's cabin volume. It's easy to understand that for vehicles with larger cabin volumes, a larger pressure relief area is required, which can be met by a pressure relief valve composed of a certain number of universal valve bodies.

[0050] In one embodiment, when the number of intermediate valve bodies 30 is greater than or equal to two, adjacent intermediate valve bodies 30 are connected side by side, and all third pressure relief openings are arranged side by side.

[0051] In one embodiment, the intermediate valve body 30 includes a third connecting portion 311 and a fourth connecting portion 312, which are located on the outer periphery of the third pressure relief opening 32. For example, along a first direction, the third connecting portion 311 is located on the side of the third frame portion 31 facing the first valve body 10, and the fourth connecting portion 312 is located on the side of the third frame portion 31 facing the second valve body 20.

[0052] The third connecting part 311 of the intermediate valve body 30 is connected to the first connecting part 111 of the first valve body 10, and the fourth connecting part 312 of the intermediate valve body 30 is connected to the second connecting part 211 of the second valve body 20.

[0053] In some embodiments, the pressure relief valve 1 has an intermediate valve body 30, wherein the first connecting portion 111 of the first valve body 10 is connected to the third connecting portion 311 of the intermediate valve body 30, and the second connecting portion 211 of the second valve body 20 is connected to the fourth connecting portion 312 of the intermediate valve body 30.

[0054] In some embodiments, a pressure relief valve 1 has two intermediate valve bodies 30, which are a first intermediate valve body and a second intermediate valve body sequentially distributed along a first direction from the head to the tail. The third connecting portion 311 of the first intermediate valve body is connected to the first connecting portion 111 of the first valve body 10, the fourth connecting portion 312 of the first intermediate valve body is connected to the third connecting portion 311 of the second intermediate valve body, and the fourth connecting portion 312 of the second intermediate valve body is connected to the second connecting portion 211 of the second valve body 20. When the pressure relief valve 1 has multiple intermediate valve bodies 30, this sequence can be followed to form a pressure relief valve with multiple intermediate valve bodies. Figure 5 The diagram illustrates the assembly process of the first valve body 10, the second valve body 20, and the intermediate valve body 30. Figure 6As shown, a three-dimensional view of the assembled pressure relief valve 1 is presented.

[0055] In the above embodiments, at least one intermediate valve body 30 is provided between the first valve body 10 and the second valve body 21. All valve bodies, including the first valve body 10, the second valve body 20, and the intermediate valve body 30, are provided with pressure relief openings (i.e., the first pressure relief opening 12, the second pressure relief opening 22, and the third pressure relief opening 32 mentioned above). By combining them in this way, the pressure relief opening area of ​​the pressure relief valve 1 can be changed, thereby meeting the pressure relief area requirements of different vehicle models. This achieves the universality of the pressure relief valve 1 in different vehicle models and saves on R&D design, mold and other development costs.

[0056] In some embodiments, the connecting surfaces of the first valve body 10, the second valve body 20, and the intermediate valve body 30 are connected by an adhesive, which can be achieved by using adhesives such as glue, pressure-sensitive adhesives, or double-sided tape.

[0057] In some embodiments, the connecting surfaces of the first valve body 10, the second valve body 20 and the intermediate valve body 30 are connected by welding, such as laser welding, ultrasonic welding or friction welding.

[0058] In some embodiments, the connecting surfaces of the first valve body 10, the second valve body 20 and the intermediate valve body 30 are connected by a snap-fit ​​method, for example, by using a snap-fit ​​and slot mating structure.

[0059] Furthermore, such as Figures 3a-3c As shown, the first connecting part 111 of the first valve body 10 includes multiple snap-fit ​​or slot structures, and the second connecting part 211 of the second valve body 20 or the third connecting part 311 of the intermediate valve body 30 that is matched and connected thereto is provided with multiple corresponding matching slots or snap-fit ​​structures, thus realizing a fixed connection between the valve bodies.

[0060] In some embodiments, such as Figures 1 to 8As shown, the first frame portion 11 of the first valve body 10 includes a first frame 112, a first sidewall 113, and a first bottom wall 114; one end of the first sidewall 113 is connected to the first bottom wall 114, and the other end of the first sidewall 113 is connected to the first frame 112. Further, the first bottom wall 114 is connected to the first sidewall 113 along at least three edges in the circumferential direction, and the first sidewall 113 includes a first outer side and a first inner side, the first inner side being the side facing the first pressure relief opening; the first frame 112 is connected to one side of the first outer side of the first sidewall 113. Furthermore, the first bottom wall 114 surrounds the periphery of the first pressure relief opening 12, and the first pressure relief opening 12 includes at least two through holes, with at least one reinforcing rib 41 between the through holes; the reinforcing rib 41 is inclined at an angle to the plane of the first bottom wall 114 or the first frame 112, and the inclined reinforcing rib 41 makes the through hole at a certain angle relative to the first bottom wall 114, thus increasing the pressure relief port area of ​​the pressure relief through hole and reducing the size of the pressure relief valve components; furthermore, the first valve body 10 is provided with a blade 60, the shape of which is approximately the same as the shape of the first pressure relief opening 12, for movable covering of the first pressure relief opening 12 at a certain angle on the first valve body 10; furthermore, a locking protrusion 42 for fixing the blade 60 is also provided on the first inner surface of the first bottom wall 114 between the through hole and the first side wall 113, and the end of the locking protrusion 42 is provided with an anti-detachment structure, thus facilitating the installation of the blade 60 and preventing the blade 60 from easily detaching when the vehicle is in motion; Figure 7 As shown, the blade 60 is further provided with at least two fixing holes 61 to ensure that the blade 60 opens and closes stably.

[0061] The second frame portion 21 of the second valve body 20 includes a second frame 212, a second sidewall 213, and a second bottom wall 214. One end of the second sidewall 213 is connected to the second bottom wall 214, and the other end of the second sidewall 213 is connected to the second frame 212. Further, the second bottom wall 214 has at least three edges along its circumference connected to the second sidewall 213. The second sidewall 213 has a second outer surface and a second inner surface, the second inner surface being the side facing the second pressure relief opening 22. The second sidewall 213 extends towards the second outer surface and is connected to the second frame 212. Furthermore, the second bottom wall 214 surrounds the periphery of the second pressure relief opening 22, which includes at least two through holes, with at least one reinforcing rib 41 between the through holes. The reinforcing rib 41 is inclined at an angle to the plane of the second bottom wall 214 or the second frame 212. The inclined reinforcing rib 41 makes the through holes inclined at a certain angle relative to the second bottom wall 214, thereby increasing the pressure relief port area of ​​the pressure relief through hole and reducing the size of the pressure relief valve components. Furthermore, the second valve body 20 is provided with a blade 60, the shape of which is approximately the same as the shape of the second pressure relief opening 22, for movable cover of the second pressure relief opening 22 inclined at a certain angle to the second valve body 20. Furthermore, a locking protrusion 42 for fixing the blade 60 is also provided on the second inner side surface of the second bottom wall 214 between the through hole and the second side wall 213. The end of the locking protrusion 42 is provided with an anti-detachment structure. This arrangement makes it easy for those skilled in the art to install the blade 60, and the blade 60 is not easily detached when the vehicle is in motion. Figure 7 As shown, the blade 60 is further provided with at least two fixing holes 61 to ensure that the blade 60 opens and closes stably. The first valve body 10 and the second valve body 20 thus formed are roughly box-shaped structures.

[0062] Furthermore, at least two of the first frame portion 111 of the first valve body 10, the first sidewall 112, the first sidewall 113, and the first bottom wall 114 are provided with first connecting surfaces, and at least two of the second frame portion 21 of the second valve body 20, the second sidewall 212, the second sidewall 213, and the second bottom wall 214 are provided with second connecting surfaces, and the first connecting surfaces and the second connecting surfaces are provided correspondingly.

[0063] As shown in the following example, when only the first valve body 10 and the second valve body 20 are connected, the first frame 112 and the first bottom wall 114 are provided with a first connecting surface; the second frame 212 and the second bottom wall 214 are provided with a second connecting surface. The first connecting surface on the first frame 112 and the second connecting surface on the second frame 212 are stacked and fitted together, and the first connecting surface on the first bottom wall 114 and the second connecting surface on the second bottom wall 214 are stacked and fitted together. Since the connecting surfaces of the frame and the bottom wall are not on the same straight line, the connecting surface structure formed therefrom is more stable.

[0064] In some embodiments, such as Figures 1 to 8As shown, the third frame portion 31 includes a third frame 313, a third sidewall 314, and a third bottom wall 315; one end of the third sidewall 314 is connected to the third bottom wall 315, and the other end of the third sidewall 314 is connected to the third frame 313; further, at least two opposite edges of the third bottom wall 315 are connected to the third sidewall 314, the third sidewall 314 is provided with a third outer side and a third inner side, the third inner side being the side facing the pressure relief opening through hole; the third sidewall 314 extends towards the third outer side and is connected to the third frame 313. The intermediate valve body 30 thus formed has a roughly groove-shaped cross-section; furthermore, at least two parts of the third frame 31, the third side wall 313, the third side wall 314, and the third bottom wall 315 of the third frame portion 31 of the intermediate valve body 30 are provided with a connecting surface of the third connecting portion 311 and a connecting surface of the fourth connecting portion 312; furthermore, the third frame, the third side wall, and the third bottom wall are not on the same straight line or in the same extending direction, and after being connected to other intermediate valve bodies 30, the first valve body 10, or the second valve body 20 by at least the third connecting surface, the assembled pressure relief valve is more robust; furthermore, the third bottom wall 315 is provided with a third pressure relief opening 32, which is composed of at least two through holes, and at least one reinforcing rib 41 is provided between the through holes; the reinforcing rib 41 The reinforcing rib 41 is inclined at an angle to the plane of the third bottom wall 315 or the third frame 313. The inclined reinforcing rib 41 makes the through hole at a certain angle relative to the third bottom wall. In this way, the pressure relief port area of ​​the pressure relief through hole can be increased and the size of the pressure relief valve components can be reduced. Furthermore, the intermediate valve body 30 is provided with a blade 60. The shape of the blade 60 is approximately the same as the shape of the third pressure relief opening 32, which is used for the third pressure relief opening 32 of the intermediate valve body 30 at a certain angle. Furthermore, a snap-fit ​​protrusion 42 for fixing the blade 60 is also provided on the third bottom wall 315. The end of the snap-fit ​​protrusion 42 is provided with an anti-detachment structure. This arrangement makes it easy for those skilled in the art to install the blade 60, and the blade 60 is not easy to detach when the vehicle is in motion. Figure 7 As shown, the blade 60 is further provided with at least two fixing holes 61 to ensure that the blade 60 opens and closes stably.

[0065] In some embodiments, the blade 60 is made of a soft material, such as soft plastic or rubber. The blade made of soft material can make better sealing contact with the valve body frame, so that the blade can cover the pressure relief opening and the sealing effect is better. Moreover, when it collides with the valve body frame during opening and closing, it can play a role in shock absorption and buffering.

[0066] In some embodiments, such as Figure 6 As shown, the outer side surface of the side wall of the pressure relief valve 1 has multiple snap-fit ​​structures 51 for mounting on the vehicle body, such as wedge-shaped snap-fit, spring snap-fit, etc. Furthermore, the snap-fit ​​structures are provided with reinforcing rib structures on both sides or around the perimeter to enable them to be firmly mounted on the vehicle body.

[0067] This application also provides a vehicle that includes the pressure relief valve of the above embodiments. The pressure relief valve is installed on the vehicle body and connects the vehicle cabin to the external environment.
