[0025] Various specific embodiments of the present application will be described below with reference to the accompanying drawings which constitute a part of this specification. It should be understood that, where possible, the same or similar reference numerals used in this application refer to the same components.

[0026] It should be understood that if terms indicating directions are used in the present application, such as "front", "rear", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc., to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the drawings. Since the embodiments disclosed in the present application can be arranged in different directions, these terms indicating directions are only used as illustrations and should not be regarded as limitations.

[0027] Figures 1a to 1f It is a pressure relief assembly 100 according to the first embodiment of the present application. Figure 1a is a perspective view of the pressure relief assembly 100 . Figure 1b yes Figure 1a Exploded view of the pressure relief assembly 100 in FIG. Figure 1c yes Figure 1a A longitudinal cross-sectional view of the pressure relief assembly 100 in FIG. Figure 1d yes Figure 1c Magnified view of the dotted box area. Figure 1e and Figure 1f They are Figure 1d The insertion portion 112 of the pressure release member 110 and the receiving groove 152 of the cover 150 are combined. Figures 1a to 1f A pressure relief assembly 100 according to a first embodiment of the present application is described.

[0028] The pressure relief assembly 100 includes a pressure relief member 110 and a cover 150. The pressure relief member 110 includes a main body 111, and a plurality of female members 116 are disposed on the main body 111. A male member 156 is disposed on the cover 150. The male member 156 is inserted into the female member 116 and is engaged with the female member 116, so that the pressure relief member 110 and the cover 150 are connected to form the pressure relief assembly 100. The male member 156 is engaged with the female member 116, so that a force perpendicular to the top surface 123 of the insertion portion 112 and the top wall 123 (described below) of the receiving groove 152 is applied to the pressure relief member 110 and the cover 150, so that the top surface 123 and the top wall 123 are engaged. It should be understood that in other embodiments, the pressure relief member 110 and the cover 150 can be connected in other ways, including but not limited to welding. The pressure relief member 110 includes a valve plate 115, and an inlet 114 and an outlet 113 located on both sides of the valve plate 115. The cover 150 includes an inlet 154, which is in communication with the inlet 114 of the pressure relief member 110. When the pressure relief assembly 100 is mounted on a vehicle, the cover 150 faces the interior of the vehicle, and the inlet 154 of the cover 150 faces upward, and the outlet 113 of the pressure relief member 110 faces the exterior of the vehicle. Therefore, when air is released from the interior of the vehicle, the air enters the pressure relief assembly 100 from the inlet 154 of the cover 150, and then enters the inlet 114 of the pressure relief member 110, and blows the valve plate 115 to open it, so that the air reaches the outlet 113 of the pressure relief member 110, and then leaves through the outlet 113 to be released from the interior of the vehicle.

[0029] The pressure relief member 110 further includes an insert portion 112 extending from the main body 111 at least partially around the main body 111. In the first embodiment of the present application, the insert portion 112 is shown to extend around the lower half of the main body 111. The insert portion 112 and the main body 111 are both made of a hard material and are formed as one piece, which is conducive to convenient manufacturing of the pressure relief member 110 and convenient assembly of the pressure relief member 110 and the cover 150. In one embodiment, the insert portion 112 and the main body 111 are integrally formed of the same hard material. The cover 150 includes a receiving groove 152, and the insert portion 112 is at least partially inserted into the receiving groove 152 and engaged with the receiving groove 152. The insert portion 112 includes a top surface 123 and side surfaces 121 and 122 located on both sides of the top surface 123, and the top surface 123 and the side surfaces 121 and 122 are planes. The receiving groove 152 is defined by opposite side walls 161 and 162, and a top wall 163 connecting the side walls 161 and 162, and the top wall 163 and the side walls 161 and 162 are planes. The side walls 161 and 162 face the side surfaces 121 and 122 respectively, and the top wall 163 faces the top surface 123. In addition, the side surface 121 is engaged with the side wall 161 to form a first engagement position, the top wall 163 is engaged with the top surface 123 to form a second engagement position, and the side surface 122 is engaged with the side wall 162 to form a third engagement position. The top surface 123 is parallel to the top wall 163, and the side surface 122 is parallel to the side wall 162. The side wall 161 has a chamfer 164 at the free end, and the chamfer 164 guides the side surface 121 to be inserted into the receiving groove 152 during the process of inserting the insertion portion 112 into the receiving groove 152. In the direction from the body 111 to the top surface 123, the side surface 121 is inclined away from the side wall 161 and is angled with the side wall 161. The angle of the side surface 121 relative to the side wall 161 is configured so that when the insert 112 is received in the receiving groove 152, the side surface 121 is interference fit with the side wall 161, so that the side wall 161 forms a sealing engagement with the side surface 121 in the first engagement position.

[0030] Assuming that the side wall 161 and the side surface 121 do not form a sealed joint at the first joint position, when water enters the pressure release assembly 100 from the outside of the vehicle through the outlet 113 and reaches the first joint position between the pressure release member 110 and the cover 150, at least part of the water can continue to flow through the second joint position and the third joint position, and then enter the interior of the vehicle. In the present application, since the side surface 121 and the side wall 161 are sealed at the first joint position, water cannot flow through the first joint position, thereby preventing water from entering the interior of the vehicle through the joint between the pressure release member 110 and the cover 150. In addition, although there is a gap between the side wall 161 and the side surface 121 located downstream of the first joint position, the gap is very small. Even if a small amount of water passes through the first joint position, the water pressure generated by the small amount of water is not enough to allow it to pass through the gap and enter the interior of the vehicle.

[0031] Furthermore, since the top wall 163 is joined to the top surface 123, and the side wall 162 is joined to the side surface 122, even if there are gaps between the top wall 163 and the top surface 123, and between the side wall 162 and the side surface 122, these gaps are very small, so even if a small amount of water passes through between the side wall 161 and the side surface 121, the water pressure generated by the small amount of water is insufficient to cause the water to enter the vehicle interior through the gaps between the top wall 163 and the top surface 123, and between the side wall 162 and the side surface 122. Therefore, the top wall 163 is joined to the top surface 123, and the side wall 162 is joined to the side surface 122, which further contributes to preventing water from entering the vehicle interior via the joint portion between the pressure release member 110 and the cover 150.

[0032] Figure 2 A partial enlarged view of a pressure relief assembly according to a second embodiment of the present application is shown. The partial enlarged view shows the configuration of the inserting portion on the pressure relief member and the receiving groove on the cover. Figure 2 The second embodiment in FIG. 1 is different from the first embodiment described above only in the number of the insertion portion 112 on the pressure release member 110 and the receiving groove 152 on the cover. Figure 2 As shown, in the second embodiment, two insertion parts 112 and two receiving grooves 152 are provided. The two insertion parts 112 are arranged in a mirror image, and are spaced apart from each other and are substantially parallel to each other, so that a groove 117 is defined between the two insertion parts 112. Correspondingly, the two receiving grooves 152 are also spaced apart from each other and are substantially parallel to each other, so that a protrusion 157 is defined between the two receiving grooves 152. The two insertion parts 112 are at least partially inserted into the corresponding receiving grooves 152, and the protrusion 157 between the two receiving grooves 152 at least partially extends into the groove 117 between the two insertion parts 112. Therefore, in this embodiment, the protrusion 157 between the two receiving grooves 152 is at least partially inserted into the groove 117 between the two insertion parts 112. Figure 2 The upper surface of the inserting portion 112 in the middle and upper part is interference fit with the upper side wall of the receiving groove 152, thereby forming a sealed contact and being located Figure 2 The lower surface of the insertion portion 112 in the middle and lower part is interference fit with the lower side wall of the receiving groove 152, thereby forming a sealed joint. Compared with only one sealed joint in the first embodiment, two sealed joints are formed in the second embodiment, which is more conducive to preventing water from entering the interior of the vehicle from the joint between the pressure release member and the cover. In addition, since the two insertion portions 112 are at least partially inserted into the corresponding receiving grooves 152, and the protrusion 157 between the two receiving grooves 152 at least partially extends into the groove 117 between the two insertion portions 112, the joint between the pressure release member and the cover defines a roughly S-shaped path, which increases the travel of water in the joint between the pressure release member and the cover, further increasing the obstacles for water to enter the interior of the vehicle from the joint between the pressure release member and the cover.

[0033] Figure 3: is a partial enlarged view of a pressure relief assembly according to a third embodiment of the present application. The partial enlarged view shows the structure of the insertion portion on the pressure relief member and the receiving groove on the cover. The third embodiment is different from the first embodiment described above only in that the side surface 121 of the insertion portion 112 and the side wall 161 of the receiving groove 152 are constructed to be parallel to each other, and a protrusion 369 is constructed on the side wall 161 of the receiving groove 152. The protrusion 369 makes the side wall 161 and the side surface 121 interference fit, so that the side wall 161 and the side surface 121 form a sealed joint.

[0034] Figure 4 A partial enlarged view of a pressure relief assembly according to a fourth embodiment of the present application is shown. The partial enlarged view shows the construction of the insertion portion on the pressure relief member and the receiving groove on the cover. The difference between this embodiment and the aforementioned third embodiment is only the protrusions on the side walls 161 and 162 of the receiving groove 152. Specifically, in this fourth embodiment, opposite protrusions 369 are respectively provided on the two side walls 161 and 162 of the receiving groove 152, so that the side wall 161 and the side surface 121, the side wall 162 and the side wall 122 form an interference fit, respectively, so that the side wall 161 and the side surface 121, the side wall 162 and the side wall 122 form a sealing joint, respectively.

[0035] Figure 5 A partial enlarged view according to the fifth embodiment of the present application is shown. The partial enlarged view shows the structure of the top surface of the insertion portion 112 and the top wall of the receiving groove 152. In the fifth embodiment, the top wall of the receiving groove 152 is a vertical plane, and the end of the insertion portion 112 is provided with a plurality of crushing ribs 529, and the crushing ribs 529 protrude toward the top wall 163, so that the top surface of the insertion portion 112 is toothed. When the insertion portion 112 is received in the receiving groove 152, the top wall of the receiving groove 152 applies force toward the crushing ribs 529 to deform the crushing ribs 529. Therefore, the top surface of the insertion portion 112 and the top wall of the receiving groove 152 also form a sealing joint. The structure of the top wall of the receiving groove 152 and the top surface of the insertion portion 112 shown in the fifth embodiment is applicable to any embodiment of the aforementioned first to fourth embodiments.

[0036] Figure 6A partial enlarged view of a pressure release assembly according to a sixth embodiment of the present application is shown. The partial enlarged view shows another configuration of the top surface of the insertion portion 112 and the top wall of the receiving groove 152. In the sixth embodiment, the top surface 623 of the insertion portion 112 is a convex surface, and the top wall of the receiving groove 152 is a concave surface complementary to the top surface 623 of the insertion portion 112. This increases the engagement area between the top surface 623 of the insertion portion 112 and the top wall of the receiving groove 152, which helps prevent water from entering the interior of the vehicle from the engagement portion between the pressure release member 110 and the cover 150. The configuration of the top wall of the receiving groove and the top surface of the insertion portion shown in the sixth embodiment is applicable to any of the first to fourth embodiments described above.

[0037] This application produces at least the following technical effects:

[0038] 1. The pressure relief member and the cover are sealed by interference fit between the inserting portion on the pressure relief member and the receiving groove on the cover, preventing water from outside the vehicle from entering the vehicle interior through the joint between the pressure relief member and the cover.

[0039] 2. Since the inserting portion on the pressure relief member is integrally formed with the main body, the pressure relief member of the present application is easy to manufacture.

[0040] 3. Since it is only necessary to insert the insertion portion on the pressure release component into the receiving groove of the cover, and then connect the pressure release component to the cover by snapping or welding to obtain the pressure release assembly, the pressure release assembly of the present application is easy to assemble.
