Description

Technical Field

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

[0002] With advancements in the automotive industry, vehicle sealing performance has improved significantly. To ensure vehicle safety, pressure relief valves are necessary to maintain pressure balance between the vehicle's interior and exterior environments. These valves are typically installed on the sheet metal on either side of the rear of the vehicle. During rainy weather or when driving through flooded areas, water can easily splash into the vehicle through the bottom air inlet of the valve, affecting vehicle performance. Therefore, a waterproof structure is required on the pressure relief valve to prevent this from happening.

[0003] Existing pressure relief valves use a shield to create a semi-enclosed structure, thus blocking the gas passage and preventing water from entering the vehicle. However, this shield installation method is structurally complex and occupies space between the rear bumper and side panels, affecting the installation of the rear bumper. Utility Model Content

[0004] Therefore, it is necessary to provide a vehicle pressure relief valve and vehicle that is simple in structure, does not occupy the space between the rear bumper and the side panel of the vehicle, and can prevent water from entering the vehicle through the pressure relief valve.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A vehicle pressure relief valve for mounting on a vehicle body, the vehicle pressure relief valve comprising at least:

[0007] The valve body includes a frame and spacers. A through groove is provided on the frame. Multiple spacers are housed in the through groove and are spaced apart along the height direction of the vehicle. Each spacer extends along the length direction of the frame and its two ends are connected to two opposite walls of the through groove. An air inlet is formed between two adjacent spacers and between the frame and its adjacent spacers.

[0008] The valve plates are arranged in a one-to-one correspondence with the number of air inlets. One end of each valve plate is rotatably connected to the valve body, and the other end can rotate relative to the valve body to open or close the air inlet.

[0009] Along the height direction of the vehicle, the lowest air inlet is configured as the first air inlet. The first air inlet is provided with an overlapping part and a blocking part. The overlapping part is used to abut against the valve plate when the valve plate is in the closed state to close the first air inlet. Along the height direction of the vehicle, the blocking part is located above the overlapping part and connected to the blocking part, and the blocking part extends along the height direction of the vehicle.

[0010] Understandably, this application uses a blocking part located inside the first air inlet to prevent rainwater or other external water from splashing into the first air inlet, thus avoiding water entering the vehicle through the first air inlet and affecting vehicle performance. At the same time, since the blocking part is located inside the first air inlet, it does not affect or occupy the installation space of other vehicle components, and it can form a waterproof line while ensuring the normal operation of the vehicle's pressure relief valve, thereby achieving its waterproof function and protecting vehicle performance.

[0011] In one embodiment, the side of the blocking portion facing the valve plate is configured as an arc-shaped surface, and the arc-shaped surface is recessed along the air intake direction of the first air inlet.

[0012] Understandably, the curved surface has good airflow guiding performance. Even if water splashes into the blocking part, it can be guided to the outside of the pressure relief valve through the curved surface, thus preventing the splashed water from entering the vehicle interior.

[0013] In one embodiment, along the height direction of the vehicle, the height of the blocking portion gradually decreases among the plurality of air inlets.

[0014] It is understandable that during vehicle operation, water generally splashes in from bottom to top along the vehicle's height. The amount of water that may splash into the air intake decreases from bottom to top along the vehicle's height. Therefore, gradually reducing the height of the barrier can reduce production costs while ensuring its waterproof function.

[0015] In one embodiment, the vehicle pressure relief valve further includes a baffle plate installed on the valve body and positioned at the connection between the valve plate and the valve body.

[0016] Understandably, the baffle is designed to prevent water flowing from the vehicle or the vehicle's pressure relief valve from entering the pressure relief valve along the valve body or valve plate, thereby further improving the waterproof performance of the vehicle's pressure relief valve.

[0017] In one embodiment, along the height direction of the vehicle, a guide opening is provided at one end of the frame near the first air inlet, and the guide opening is connected to the through slot.

[0018] Understandably, the guide port serves to guide the flow. After water splashes onto the arc-shaped surface of the blocking part and flows out from the arc-shaped surface, it can flow out completely through the guide port to the outside of the vehicle's pressure relief valve, thus preventing the water flowing out from the arc-shaped surface from re-entering the vehicle's pressure relief valve.

[0019] In one embodiment, the vehicle pressure relief valve further includes a support rod disposed inside the air inlet, with both ends of the support rod connected to two walls of the air inlet along the height direction of the vehicle.

[0020] Understandably, the support rod not only supports the spacer and enhances its structural strength, but also prevents some water from splashing directly into the vehicle's pressure relief valve, further improving the overall waterproof performance of the vehicle's pressure relief valve structure.

[0021] In one embodiment, the vehicle pressure relief valve further includes a mounting bracket and a sealing ring, the mounting bracket being used to connect to the vehicle body; the valve body is mounted on the mounting bracket, and the sealing ring is sleeved around the valve body.

[0022] In one embodiment, the mounting bracket is provided with snap-fit ​​buckles and snap-fit ​​holes, and the snap-fit ​​buckles and snap-fit ​​holes are located on different sides of the mounting bracket.

[0023] In one embodiment, the vehicle pressure relief valve further includes a boss located at one end of the frame along the height direction of the vehicle and away from the first air inlet.

[0024] This application also provides the following technical solutions:

[0025] A vehicle includes a body and a vehicle pressure relief valve as described in the above embodiments, the vehicle pressure relief valve being installed on the body.

[0026] Compared with the prior art, the vehicle pressure relief valve and the vehicle described herein have a blocking part installed inside the first air inlet. The blocking part prevents rainwater and other external water from splashing into the first air inlet, thus preventing water from entering the vehicle through the first air inlet and affecting vehicle performance. At the same time, since the blocking part is installed inside the first air inlet, it does not affect or occupy the installation space of other vehicle components, and it can form a waterproof line while ensuring the normal operation of the vehicle pressure relief valve, thereby achieving its waterproof function and ensuring vehicle performance.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0039] Please see Figures 1 to 5 This application provides a vehicle pressure relief valve 100, which can be installed on the vehicle body 200 and can prevent rainwater or other substances from splashing into the vehicle and affecting vehicle performance when the vehicle is driving in rainy weather or on flooded roads.

[0040] Specifically, the vehicle pressure relief valve 100 includes at least a valve body 10 and valve plates 20. The valve body 10 includes a frame 11 and spacers 12. A through groove 111 is provided on the frame 11. Multiple spacers 12 are housed in the through groove 111 and are spaced apart along the height direction z of the vehicle. Each spacer 12 extends along the length direction x of the frame 11, and both ends of the spacer 12 are connected to two opposite walls 121 of the through groove 111. An air inlet 13 is formed between two adjacent spacers 12 and between the frame 11 and its adjacent spacers 12. The number of valve plates 20 corresponds one-to-one with the number of air inlets 13. Furthermore, one end of the valve plate 20 is rotatably connected to the valve body 10, and the other end can rotate relative to the valve body 10 to open or close the air inlet 13; wherein, along the height direction z of the vehicle, the lowermost air inlet 13 is configured as the first air inlet 131, and the first air inlet 131 is provided with an overlapping part 14 and a blocking part 15. The overlapping part 14 is used to abut against the valve plate 20 when the valve plate 20 is in the closed state to close the first air inlet 131; along the height direction z of the vehicle, the blocking part 15 is located above the overlapping part 14 and connected to the blocking part 15, and the blocking part 15 extends along the height direction z of the vehicle.

[0041] It is understandable that when the driver or passenger turns on the external air circulation mode of the vehicle, the valve plate 20 of the vehicle pressure relief valve 100 will be in the open state, that is, the air inlet 13 will be open. At this time, if the vehicle is driving in rain or wading through water, water droplets will drip or splash from the driving ground into the pressure relief valve and enter the vehicle interior through the air inlet 13 of the pressure relief valve, thereby affecting the performance of the vehicle body 200. The relevant technology is to set a waterproof structure on the pressure relief valve to avoid the above phenomenon. However, the waterproof structure of the common vehicle pressure relief valve 100 is generally set on the outside of the valve body 10, which affects the operation of the pressure relief valve and the installation of vehicle components, and the structure is also more complicated. Therefore, this application provides a blocking part 15, which is located inside the first air inlet 131. The blocking part 15 prevents rainwater and other external water from splashing into the first air inlet 131, thus preventing water from entering the vehicle through the first air inlet 131 and affecting vehicle performance. At the same time, since the blocking part 15 is located inside the first air inlet 131, it does not affect or occupy the installation space of other vehicle components, and it can form a waterproof line while ensuring the normal operation of the vehicle pressure relief valve 100, thereby achieving its waterproof function and ensuring vehicle performance.

[0042] In this embodiment, the length direction x and the height direction z are set at an angle. Here, the angle between the length direction x and the height direction z can be 85 degrees, 90 degrees, 95 degrees, etc.

[0043] like Figure 2 and Figure 3As shown, along the height z direction of the vehicle, a guide port 112 is provided at one end of the frame 11 near the first air inlet 131, and the guide port 112 is connected to the through channel 111. Here, the guide port 112 serves to guide the flow. After rainwater hits the inside of the through channel 111 and water splashes into the blocking part 15 and flows out from the blocking part 15, some of it can flow out quickly through the guide port 112 to the outside of the vehicle pressure relief valve 100, so as to prevent the water flowing out from the blocking part 15 from re-entering the vehicle pressure relief valve 100.

[0044] In one embodiment, the spacer 12 and the frame 11 can be integrally formed to improve the structural strength of the entire valve body 10, and also to facilitate the processing and forming of the valve body 10.

[0045] Please continue to refer to this. Figure 3 Along the vehicle's height direction z, the height of the blocking part 15 gradually decreases among the multiple air inlets 13. It is understandable that during vehicle operation, water generally splashes in from lower to higher positions along the vehicle's height direction z. The amount of water that may splash into the air inlets 13 decreases sequentially from lower to higher positions along the vehicle's height direction z. Therefore, along the vehicle's height direction z, the height of the higher blocking part 15 does not need to be set too high to achieve the purpose of blocking water, thus reducing production costs while ensuring the waterproof function of the blocking part 15.

[0046] Furthermore, the side of the blocking portion 15 facing the valve plate 20 is configured as an arc-shaped surface 151, and the arc-shaped surface 151 is concave along the air intake direction of the first air inlet 131. In this way, water splashed onto the blocking portion 15 can be guided out through the arc-shaped surface 151, and the guided water can flow out from the guide port 112 to the outside of the vehicle pressure relief valve 100, thereby preventing splashed water from entering the vehicle interior.

[0047] Please continue to refer to this. Figure 1 and Figure 2 The vehicle pressure relief valve 100 also includes a baffle 30, which is installed on the valve body 10 and blocks the connection between the valve plate 20 and the valve body 10. In this way, the baffle 30 can block water flowing down from the vehicle or the vehicle pressure relief valve 100, preventing water from entering the vehicle pressure relief valve 100 along the valve body 10 or the valve plate 20, thereby further improving the waterproof performance of the vehicle pressure relief valve 100.

[0048] Specifically, the baffle 30 is mounted on the spacer 12 and is integrated with the spacer 12.

[0049] like Figure 2As shown, the vehicle pressure relief valve 100 also includes a support rod 40, which is disposed inside the air inlet 13 and its two ends are respectively connected to two walls 121 of the air inlet 13 along the height direction z of the vehicle. It can be understood that the support rod 40 not only supports the spacer 12, improving its structural strength, but also prevents some water from splashing directly into the vehicle pressure relief valve 100, further improving the overall waterproof performance of the vehicle pressure relief valve 100.

[0050] Preferably, multiple support rods 40 are provided, and the multiple support rods 40 are spaced apart along the length direction x. In this way, support for the air inlet 13 is formed at multiple locations.

[0051] Please refer to Figure 4 The vehicle pressure relief valve 100 also includes a mounting bracket 50, which is used to connect to the vehicle body 200 and the valve body 10 is mounted on the mounting bracket 50, thus realizing the installation of the valve body 10 on the vehicle body 200.

[0052] In one embodiment, the mounting bracket 50 is provided with a snap-fit ​​buckle 51 and a snap-fit ​​hole 52, and the snap-fit ​​buckle 51 and the snap-fit ​​hole 52 are located on different sides of the mounting bracket 50. In this way, the snap-fit ​​buckle 51 and the snap-fit ​​hole 52 can assist the mounting bracket 50 in being installed on the vehicle body 200, and the connection between the mounting bracket 50 and the vehicle body 200 can be achieved from different directions, effectively ensuring that the vehicle pressure relief valve 100 can be stably installed on the vehicle body 200.

[0053] Furthermore, the vehicle pressure relief valve 100 also includes a sealing ring 60, which is sleeved around the valve body 10. In this way, the sealing ring 60 can seal the connection between the mounting bracket 50 and the vehicle body 200, thereby preventing rainwater and other substances from entering the vehicle through the gap between them.

[0054] Please continue to refer to this. Figure 1 and Figure 2 The vehicle pressure relief valve 100 also includes a boss 70, which is located at the end of the frame 11 along the height direction z of the vehicle and away from the first air inlet 131. Here, the boss 70 is used for positioning on the mold during the production of the vehicle pressure relief valve 100 to improve the standardization of the production process. In related technologies, the boss is generally located at the end of the frame 11 near and away from the first air inlet 131. In this case, when rainwater drips down, it is easy to hit the boss and splash back into the first air inlet 131. However, in this application, the boss 70 is located at the end of the frame 11 along the height direction z of the vehicle and away from the first air inlet 131, which further effectively prevents rainwater from splashing into the first air inlet 131.

[0055] like Figure 4As shown, the vehicle pressure relief valve 100 is also provided with reinforcing ribs 80, which are provided on the mounting bracket 50 and / or the frame 11, thereby improving the structural strength of the valve body 10 and the mounting bracket 50 and increasing their service life.

[0056] This application also provides a vehicle, including a body 200 and a vehicle pressure relief valve 100 as described in the above embodiments, wherein the vehicle pressure relief valve 100 is installed on the body 200.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
