Description

Technical Field

[0001] This application relates to a pressure relief valve, particularly a pressure relief valve used to maintain pressure balance inside and outside a vehicle. Background Technology

[0002] The pressure relief valve in a vehicle is used to maintain the pressure balance between the inside and outside of the vehicle. The pressure relief valve has a fluid passage and a valve plate covering the fluid passage. When the pressure inside the vehicle is too high (such as when the doors are closed or the windows are closed while driving), the valve plate can open under pressure to balance the pressure inside and outside the vehicle.

[0003] Currently, when transporting multiple pressure relief valves, they need to be stacked sequentially and placed in corresponding packaging boxes according to rows and columns. Each packaging box typically holds multiple rows and columns of pressure relief valves. For stability during movement, cushioning materials or partitions are usually placed in the pressure relief valve packaging boxes to prevent the valves from tilting or tipping over. Utility Model Content

[0004] The inventors of this application, through investigation and research, discovered that existing pressure relief valves improve stability during movement by using partitions and cushioning materials in the packaging box, but the valves can still tilt or tip over. To further improve the stability of multiple pressure relief valves placed in a packaging box during transportation, this application provides a pressure relief valve. The pressure relief valve includes a body having a length direction, a width direction, and a thickness direction. The body includes: a fluid channel, a circumferential edge, at least one lateral connecting portion, and at least one lateral mating portion. The fluid channel extends through the body along the thickness direction. The circumferential edge surrounds the fluid channel. The lateral connecting portion and the lateral mating portion are connected to and opposite to the circumferential edge. The lateral connecting portion and the lateral mating portion are configured to detachably connect adjacent pressure relief valves arranged side-by-side along the length and / or width direction of the pressure relief valve.

[0005] As described above, in the pressure relief valve, the lateral connecting portion includes a protrusion, and the lateral mating portion includes a recess, wherein the protrusion can enter the recess to connect adjacent pressure relief valves.

[0006] As described above, the pressure relief valve further includes a connecting arm extending outward from the circumferential edge portion. The protrusion is connected to the distal end of the connecting arm and extends beyond at least one side of the connecting arm in the extending direction of the circumferential edge portion. The lateral mating portion includes two mating arms extending outward from the circumferential edge portion. The distal ends of the mating arms are bent toward each other, thereby forming the recess with the two mating arms and the circumferential edge portion.

[0007] As described above, in the pressure relief valve, the protrusion is connected to the distal end of the connecting arm and extends beyond both sides of the connecting arm in the extending direction of the circumferential edge portion. The dimension of the connecting arm in the extending direction of the circumferential edge portion is greater than half the distance between the distal and proximal ends of the transverse connecting portion.

[0008] As described above, in the pressure relief valve, the recess extends along the thickness direction of the pressure relief valve and has an opening at at least one end in the thickness direction of the pressure relief valve. The shapes of the recess and the protrusion are configured such that the protrusion can be inserted into the recess from the opening along the thickness direction of the pressure relief valve.

[0009] As described above, in the thickness direction of the pressure relief valve, one end of the convex portion has a guide portion with a gradually decreasing size, and one end of the concave portion has a receiving portion with a gradually increasing size.

[0010] As described above, the pressure relief valve has a circumferential edge portion including a first side portion and a second side portion arranged along the length direction of the pressure relief valve. The first side portion and the second side portion are respectively provided with the lateral connecting portion and the lateral mating portion, so that the first side portion can be connected to the second side portion of the adjacent pressure relief valve.

[0011] As described above, the circumferential edge portion includes a third side portion and a fourth side portion arranged along the width direction of the pressure relief valve. The third side portion and the fourth side portion are respectively provided with the lateral connecting portion and the lateral mating portion, so that the third side portion can be connected to the second side portion and / or the fourth side portion of the adjacent pressure relief valve.

[0012] As described above, the pressure relief valve further includes a valve plate. In the thickness direction of the pressure relief valve, the main body has a front side and a rear side. The valve plate is disposed on the front side of the main body, and the lateral connecting portion and the lateral mating portion are disposed near the front side of the main body.

[0013] As described above, the pressure relief valve has a body with a vertical connecting portion and a vertical mating portion arranged opposite each other along the thickness direction, one of which can be inserted into the other to detachably connect adjacent pressure relief valves stacked in the thickness direction of the pressure relief valve.

[0014] When transporting pressure relief valves, multiple valves are typically packed sequentially in a box. The box is usually larger than a single valve. Within the box, the valves are stacked along their thickness and arranged side-by-side along their length and width. During transport, the valves may wobble or shift due to bumps and vibrations. In this application, the pressure relief valves can be connected to adjacent valves in the thickness, length, and width directions. The multiple valves packed in the box form a single unit, making it easier for each valve to maintain its original position during transport and preventing tilting or displacement.

[0037] In this application, "lateral" mainly refers to the length direction L and the width direction W; in this application, "vertical" mainly refers to the thickness direction D.

[0038] Figure 1A This is a perspective view of the pressure relief valve 100 of the first embodiment in this application. Figure 1B yes Figure 1A Another perspective view of the pressure relief valve 100 of the first embodiment. The pressure relief valve 100 of this application is installed on a vehicle to maintain the air pressure balance inside and outside the vehicle compartment.

[0039] like Figure 1A and Figure 1BAs shown, the pressure relief valve 100 includes a body 101 and a valve plate 102. The body 101 has a length direction L, a width direction W, and a thickness direction D. In the thickness direction of the body 101, the body 101 has a front side 111 and a rear side 112 disposed opposite to each other. In one application of this application, the rear side 112 faces the interior of the vehicle compartment, and the front side 111 faces the exterior of the vehicle compartment. The body 101 includes a central portion 105, an outer frame portion 106, a plurality of lateral connecting portions 181, a plurality of lateral mating portions 182, two vertical connecting portions 183, and two vertical mating portions 184. The central portion 105 has a fluid passage 150 extending along the thickness direction D of the body 101 and penetrating the body 101. The fluid passage 150 is capable of communicating fluid at the front side 111 and the rear side 112 of the body 101. When the pressure relief valve is installed on a vehicle, the fluid passage 150 is capable of communicating fluids inside and outside the vehicle. The valve plate 102 is installed on the front side 111 of the front body 101 and covers the fluid passage 150 to close the fluid passage 150. The valve plate 102 is capable of moving or deforming when the pressure on both sides of the pressure relief valve changes to open the fluid passage 150. The outer frame portion 106 is disposed around the central portion 105 and extends outward from one end of the central portion 105 near the front side 111. The outer frame portion 106 includes circumferential edge portions 180 disposed around the outer periphery of the outer frame portion 106. The outer frame portion 106 is generally rectangular, and the circumferential edge portions 180 have a first side portion 121 and a second side portion 122 that are disposed opposite each other and extend along the length direction of the pressure relief valve 100, and a third side portion 123 and a fourth side portion 124 that are disposed opposite each other and extend along the width direction of the pressure relief valve 100.

[0040] like Figure 1A and Figure 1B As shown, multiple lateral connecting portions 181 and multiple lateral mating portions 182 extend outward from the circumferential edge portion 180. The lateral connecting portions 181 can be inserted into the lateral mating portions 182 to detachably connect two adjacent pressure relief valves 100 arranged side-by-side along the length and / or width directions. In one embodiment of this application, three lateral mating portions 182 are provided on the first side portion 121, and two lateral mating portions 182 are provided on the third side portion 123. Three lateral connecting portions 181 are provided on the second side portion 122, and two lateral mating portions 182 are provided on the fourth side portion 124. Each lateral connecting portion 181 and each lateral mating portion 182 has the same structure, differing only in their connection positions. The structure is described below using one lateral mating portion 182 on the first side portion 121 and one lateral connecting portion on the fourth side portion 124 as examples.

[0041] like Figure 1BAs shown, both the lateral connecting portion 181 and the lateral mating portion 182 are located near the front side 111 of the main body 101. The lateral connecting portion 181 includes a connecting arm 171 and a protrusion 172. The connecting arm 171 extends outward from the fourth side portion 124, and the protrusion 172 connects to the distal end of the connecting arm 171 and extends beyond both sides of the connecting arm 171 in the extending direction of the fourth side portion 124 (i.e., the width direction of the pressure relief valve). Along the direction from the front side 111 to the rear side 112, the end of the protrusion 172 near the rear side 112 gradually decreases in size in both the width and length directions of the pressure relief valve, thereby forming a guide portion 188. In one embodiment of this application, in the extending direction of the fourth side portion 124, the size of the portion of the protrusion 172 extending beyond the connecting arm 171 is not less than half the size of the connecting arm 171. The size of the connecting arm 171 in the extending direction of the fourth side portion 124 is greater than half the distance between the distal and proximal ends of the lateral connecting portion 181. That is, the connecting arm 171 has a certain width in the extending direction of the fourth side portion 124, so that the connecting arm 171 has good strength and is not easy to break. In one embodiment of this application, the connecting arm 171 has a hollow portion 173 that extends through the connecting arm 171 along the thickness direction of the pressure relief valve 100. The hollow portion 173 facilitates the processing and forming of the transverse connecting portion 181. The transverse mating portion 182 includes two mating arms 176 and 177, which extend outward from the first side portion 121 of the circumferential edge portion 180. The distal ends of the mating arms 176 and 177 bend towards each other, so that the two mating arms 176 and the first side portion 121 of the circumferential edge portion 180 form a recess 178. The recess 178 extends along the thickness direction of the pressure relief valve and penetrates the transverse mating portion 182, thereby forming openings 195 and 196 in the thickness direction. The protrusion 172 can enter the transverse mating portion 182 along the thickness direction from the opening 195 or 196. Along the direction from the front side 111 to the rear side 112, the end of the recess 178 near the rear side 112 gradually increases in size in the extending direction of the first side of the pressure relief valve (i.e., the length direction of the pressure relief valve), thereby forming a receiving portion 198. The dimensions of the guide portion 188 and the receiving portion 198 facilitate the entry of the protrusion 172 into the recess 178. In one embodiment of this application, both the guide portion 188 and the receiving portion 198 are near the rear side 112, and the protrusion 172 can be guided into the recess 178 in both insertion directions. In the direction from the front side 111 to the rear side 112, the guide portion 188 guides the protrusion 172 into the recess 178. In the direction from the rear side 112 to the front side 111, the receiving portion 198 guides the protrusion 172 into the recess 178. In another embodiment of this application, the guide portion and the receiving portion are disposed opposite to each other, close to the front and rear sides respectively, so that the protrusion can be guided into the recess in an insertion direction.

[0042] like Figure 1A and Figure 1BAs shown, in the thickness direction of the pressure relief valve, two vertical connecting portions 183 and two vertical mating portions 184 are respectively disposed on both sides of the outer frame portion 106. The vertical connecting portions 183 can be inserted into the vertical mating portions 184 to detachably connect two adjacent pressure relief valves 100 stacked in the thickness direction. In one embodiment of this application, both vertical connecting portions 183 and two vertical mating portions 184 are disposed close to the first side portion 121. Each vertical connecting portion 183 and each vertical mating portion 184 has the same structure, only the connection position is different. The structure is described below using one vertical connecting portion 183 and one vertical mating portion 184 as an example.

[0043] like Figure 1A As shown, the vertical connecting portion 183 extends from the outer frame portion 106 toward the rear side 112 along the thickness direction of the pressure relief valve 100. The vertical connecting portion 183 is generally plate-shaped, and its outer side is provided with multiple raised ribs 165 extending along the thickness direction of the pressure relief valve 100. The raised ribs 165 enhance the friction between the vertical connecting portion 183 and the vertical mating portion 184 when they are connected. Figure 1B As shown, the vertical mating part 184 extends from the outer frame part 106 in a direction away from the front side 111. The outer wall 153 of the vertical mating part 184 and the side wall 154 of the center part 105 form a groove 169, which can receive the vertical connecting part 183.

[0044] Figure 2 yes Figure 1A A 3D view showing multiple pressure relief valves arranged side-by-side and connected. (Example) Figure 2As shown, pressure relief valves 100a, 100b, 100c, 100d, and 100e have the same structure as pressure relief valve 100 in Figure 1. Pressure relief valves 100a, 100b, and 100c are arranged sequentially along the width direction of pressure relief valve 100a. The second side of pressure relief valve 100a is adjacent to the first side of pressure relief valve 100b. The lateral connecting portion 181 on the second side of pressure relief valve 100a is connected to the lateral mating portion 182 on the first side of pressure relief valve 100b, thereby connecting pressure relief valve 100a and pressure relief valve 100b. Similarly, pressure relief valve 100b is connected to pressure relief valve 100c. Pressure relief valves 100d and 100e are arranged along the width direction of pressure relief valve 100a and are close to the fourth side of pressure relief valves 100a, 100b, and 100c. The lateral mating portion on the third side of pressure relief valve 100d connects to the lateral connecting portion on the fourth side of pressure relief valve 100e, thereby connecting pressure relief valve 100d and pressure relief valve 100e. The lateral connecting portion on the fourth side of pressure relief valve 100a connects to the lateral mating portion on the first side of pressure relief valve 100d, thereby connecting pressure relief valve 100a and pressure relief valve 100d. Similarly, pressure relief valve 100c is connected to pressure relief valve 100e. Each of pressure relief valves 100a, 100b, 100c, 100d, and 100e can be connected to an adjacent pressure relief valve. In other embodiments of this application, the number of pressure relief valves arranged side-by-side can be set as needed.

[0045] like Figure 2 As shown, when the transverse connecting portion 181 is connected to the transverse mating portion 182, the protrusion 172 of the transverse connecting portion 181 is located in the recess 178 of the transverse mating portion 182. The protrusion 172 is restricted by the recess 178 and cannot leave the recess 178 along the length or width direction of the pressure relief valve. During connection and disassembly, the protrusion 172 enters or leaves the recess 178 along the thickness direction of the pressure relief valve. In one embodiment of this application, the size of the recess 178 is set to be slightly larger than the size of the protrusion 172 so that the protrusion 172 can easily enter the recess 178.

[0046] In this application, through the cooperation of the transverse connecting part and the transverse mating part, each pressure relief valve arranged side by side along the length or width direction of the pressure relief valve can be connected to the adjacent pressure relief valve.

[0047] Figure 3 yes Figure 1A A perspective view showing the connection of two stacked pressure relief valves. Pressure relief valves 100f and 100g have the same structure as pressure relief valve 100 in Figure 1. Pressure relief valves 100f and 100g are arranged along the thickness direction of pressure relief valve 100f. At this time, the vertical connecting portion 183 of pressure relief valve 100f (see Figure 1)... Figure 1AThe pressure relief valve 100f enters the vertical mating part 184 of the pressure relief valve 100g, thereby connecting the pressure relief valve 100f to the pressure relief valve 100g. When the pressure relief valves are stacked along the thickness direction, they are connected to adjacent pressure relief valves through the vertical connecting part and the vertical mating part.

[0048] Combination Figure 2 and Figure 3 As shown in this application, multiple pressure relief valves can be connected to adjacent pressure relief valves arranged side by side via lateral connecting parts and lateral mating parts, thereby forming an interconnected layer of pressure relief valves in the packaging box. Each layer of pressure relief valves is connected to the pressure relief valves of the adjacent layer via vertical connecting parts and vertical mating parts, thus forming a whole pressure relief valve system in the packaging box. That is to say, the pressure relief valves in the packaging box can be connected to adjacent pressure relief valves in the thickness direction, length direction, and width direction.

[0049] Figure 4 This is a perspective view of the main body of the pressure relief valve in the second embodiment of this application. Figure 4 The pressure relief valve body shown is Figure 1A and 1B The pressure relief valves shown are similar in body, except that... Figure 4 The shapes of the transverse connecting parts and transverse mating parts are different.

[0050] like Figure 4 As shown, the pressure relief valve 400 has multiple transverse connecting parts 471 around its perimeter. Each transverse connecting part 471 has the same structure and can connect with the transverse connecting part of an adjacent pressure relief valve. That is, with... Figure 1A Compared to the embodiments shown, Figure 4 The transverse connecting part has Figure 1A The transverse connecting portion and transverse mating portion of the embodiment function as follows: The transverse connecting portion 471 includes a first connecting arm 431, a second connecting arm 432, and a third connecting arm 433. The first connecting arm 431 extends outward from the circumferential edge portion 480 of the pressure relief valve 400, and its distal end bends toward the second connecting arm 432 to form a first protrusion 441. The second connecting arm 432 extends outward from the circumferential edge portion 480 of the pressure relief valve 400, and its distal end protrudes toward both the first connecting arm 431 and the third connecting arm 433 to form a second protrusion 442. The third connecting arm 433 extends outward from the circumferential edge portion 480 of the pressure relief valve 400, and its distal end bends toward the second connecting arm 432 to form a third protrusion 443. The first connecting arm 431 and the second connecting arm 432 form a first recess 451 with the circumferential edge portion 480, and the third connecting arm 433 and the second connecting arm 432 form a second recess 452 with the circumferential edge portion 480.

[0051] Figure 5 yes Figure 4 A 3D view of the pressure relief valve 400 connected to an adjacent pressure relief valve. (See diagram below.) Figure 5 As shown, when one pressure relief valve is connected to an adjacent pressure relief valve, the second protrusion 442 can enter one of the first recess 451 or the second recess 452 to connect the two pressure relief valves. Simultaneously with the second protrusion 442 entering the corresponding recess, one of the first protrusion 441 or the third protrusion 443 can enter the other recess, thereby enhancing the stability of the connection between the two adjacent pressure relief valves.

[0052] Figure 4 The illustrated embodiments are capable of achieving Figure 1A and Figure 1B Similar technical effects to those in the Chinese embodiments.

[0053] When transporting pressure relief valves, multiple valves are typically packed in a box. The box is usually larger than a single valve. Inside the box, the valves are stacked along their thickness and arranged side-by-side along their length and width. During transport, the valves may tilt, sway, or shift due to bumps and vibrations. In existing technology, partitions and cushioning materials are used in the box to fill the gaps between the valves, reducing tilting, swaying, and shifting. This packaging method is cumbersome and inefficient. In this application, the pressure relief valves can be connected to adjacent valves in the thickness, length, and width directions. Multiple valves packed in the box form a single unit, making it easier for each valve to maintain its original position and preventing shifting during transport.
