For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] Reference Figures 1 to 3 , shows a schematic structural diagram of a pressure relief valve cover described in an embodiment of the present application, the pressure relief valve cover is used to shield the pressure relief valve, and the pressure relief valve cover may specifically include: a top plate 10, a side plate 20 and a folding plate 30; the side plate 20 is connected to the top plate 10, the folding plate 30 is connected to the side of the side plate 20 away from the top plate 10, the side plate 20 and the folding plate 30 form a shielding surface for the pressure relief valve; the folding plate 30 can be folded toward the side plate 20 to adjust the area of the shielding surface of the pressure relief valve.
[0040] In the embodiment of the present application, specifically, the folding plate 30 is connected to the side plate 20, and the side plate 20 and the folding plate 30 can jointly form the shielding surface for the pressure relief valve, and the folding plate 30 is arranged to be foldable toward the side plate 20 by flipping, so that the area of the shielding surface of the pressure relief valve by the folding plate 30 can be changed, thereby realizing the adjustment of the area of the shielding surface of the pressure relief valve by folding the folding portion 32 toward the side plate 20.
[0041] Specifically, in the embodiment of the present application, when the area of the shielding surface of the side panel 20 and the folding panel 30 for the pressure relief valve is large, it can have a good blocking effect on the airflow and noise outside the vehicle, so that the vehicle has a good NVH performance. When the area of the shielding surface of the side panel 20 and the folding panel 30 for the pressure relief valve is small, the air pressure inside the vehicle can be discharged more smoothly, so that the vehicle has a good ear pressure performance and improves the passenger experience. By flipping and folding the folding panel 30 on the side panel 20, the area of the shielding surface of the pressure relief valve is adjusted, so that the pressure relief valve cover has a good blocking effect on the airflow and noise outside the vehicle, while also allowing the air pressure inside the vehicle to be discharged more smoothly. Thereby taking into account both the NVH performance and the ear pressure performance of the vehicle.
[0042] In this way, the folding portion 32 can be folded according to actual needs, for example Figure 1 As shown, the folding portion 32 is completely folded to the side plate 20, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is small; or Figure 2 As shown, part of the folded portion 32 is folded to the side plate 20, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is smaller; Figure 3 As shown, the folding portion 32 may not be folded, so that the pressure relief valve cover has the largest shielding surface area for the pressure relief valve. In this way, by adjusting the area of the folding plate 30 folded to the side plate 20, the area of the shielding surface of the pressure relief valve cover for the pressure relief valve can be flexibly adjusted.
[0043] Therefore, the area of the shielding surface of the pressure relief valve can be adjusted according to the actual situation of the vehicle in the later stage, so that the vehicle has both good NVH (Noise, Vibration, Harshness) performance and ear pressure performance. This avoids the large deviation between the shielding effect of the pressure relief valve cover of the actual vehicle on the pressure relief valve and the previous simulation state, so that the actual state of the vehicle has good NVH performance and ear pressure performance, and there is no need to re-open the pressure relief valve cover, which improves production efficiency.
[0044] In the embodiment of the present application, specifically, the pressure relief valve cover is arranged on the side of the rear compartment of the vehicle, and the top plate 10 and the side plate 20 can be enclosed to form a cavity, and the gas in the vehicle can be discharged from the pressure relief valve and transmitted along the cavity to the outside of the vehicle. The top plate 10 is connected to the top of the side plate 20, and the cavity can be closed in the height direction from bottom to top of the vehicle. In addition, the side plate 20 is arranged to extend along the length direction of the vehicle and the width direction of the vehicle respectively, so that the surface of the pressure relief valve cover along the direction from front to back of the vehicle is an open surface, and the surface along the direction from top to bottom of the vehicle is an open surface. In this way, the gas in the vehicle can be transmitted from the front to back direction to the rear end of the vehicle, and from the top to bottom direction to the bottom of the vehicle, so as to avoid the gas in the vehicle from being transmitted to the upper and front ends of the vehicle, and avoid affecting the passengers in the vehicle, so that the NVH performance of the vehicle is better.
[0045] For example, in the embodiment of the present application, the top plate 10, the side plate 20 and the folding plate 30 can be an integrally formed structure, and a bending groove is provided on the folding plate 30 to realize the folding of the folding plate 30 toward the side plate 20. In this way, the connection strength between the top plate 10, the side plate 20 and the folding plate 30 is high, and the material loss and manufacturing process are reduced. In addition, the top plate 10, the side plate 20 and the folding plate 30 can also be a split structure, for example, the connection between the top plate 10 and the side plate 20 is realized by welding, and the folding plate 30 can be folded toward the side plate 20 by hinges, etc. The embodiment of the present application does not limit the specific molding method of the top plate 10, the side plate 20 and the folding plate 30.
[0046] Optionally, in the embodiment of the present application, the folding plate 30 includes a connecting portion 31 and a plurality of folding portions 32; the plurality of folding portions 32 are connected in a vertical direction, and the folding portions 32 can be folded toward the side plate 20; the connecting portion 31 is connected to one end of the plurality of folding portions 32 away from the side plate 20, and the connecting portion 31 is connected to the side plate 20. In this way, by folding different numbers of folding portions 32, one or more folding portions 32 are folded on the side plate 20, so that the folding portion 32 has a more flexible and diverse adjustment method, and realizes a variety of adjustment methods of the folding portion 32 to the area of the shielding surface of the pressure relief valve. And the connecting portion 31 away from the side plate 20 is connected to the side plate 20, so that a more stable and reliable connection is achieved between the folding plate 30 and the side plate 20.
[0047] Specifically, in the embodiment of the present application, each folding portion 32 can be folded toward the side panel 20, and two adjacent folding portions 32 can also be folded with each other. For example, the areas of each folding portion 32 can be the same, and in addition, the areas of each folding portion 32 can also be different, which can be set according to actual needs. The embodiment of the present application does not limit the specific setting method of the area of each folding portion 32.
[0048] For example, in the embodiment of the present application, among the multiple interconnected folding parts 32, the folding part 32 close to the side panel 20 can be a top folding part, the folding part 32 away from the side panel 20 can be a bottom folding part, and the folding part 32 located between the top folding part and the bottom folding part can be a middle folding part; two adjacent folding parts 32 can be folded relative to each other, and the tail folding part is connected to the side panel 20 or the middle folding part or the top folding part. For example, the top folding part and the bottom folding part can be one each, and the number of the middle folding parts can be one or more, which is not limited in the embodiment of the present application.
[0049] like Figures 1 to 3 , showing the case where the top folding part, the middle folding part and the bottom folding part are each one. Figure 1 As shown, the top folded portion, the middle folded portion and the bottom folded portion can all be folded on the side plate 20, so that the area of the pressure relief valve cover shielding the pressure relief valve is minimized. Figure 2 As shown, the middle folded portion and the bottom folded portion are folded on the side plate 20, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is larger. Figure 3 As shown, the top folding portion, the middle folding portion and the bottom folding portion are not folded, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is maximized, and a variety of different adjustment methods of the shielding surface of the pressure relief valve cover to the pressure relief valve are realized.
[0050] Optionally, in an embodiment of the present application, the side panel 20 includes a plurality of sub-side panels, two adjacent sub-side panels are intersected and connected, and the sub-side panels are connected to the top panel 10, and the folding plate 30 includes a plurality of sub-folding panels; the sub-folding plate is connected to the side of the sub-side panel away from the top panel 10 to form a sub-shielding surface for the pressure relief valve, and the sub-folding plate can be folded toward the sub-side panel to adjust the area of the sub-shielding surface.
[0051] Specifically, two adjacent sub-side panels are intersected and connected, and multiple sub-side panels can extend in different directions. Multiple sub-shielding surfaces are formed by multiple sub-side panels and multiple sub-folding panels, respectively, so that the airflow in multiple different directions outside the vehicle can be blocked to improve the blocking effect; or the airflow inside the vehicle is discharged from multiple different directions to improve the exhaust efficiency. For example, in the embodiment of the present application, the number of the sub-side panels can be 2, 3, etc., and can be set according to actual needs. The specific number of the sub-side panels and the folding panels 30 in the embodiment of the present application is not limited.
[0052] In the embodiment of the present application, specifically, the side panel 20 includes a first side panel 21 and a second side panel 22 which are vertically connected, and the first side panel 21 and the second side panel 22 are respectively connected to the top panel 10, and the folding panel 30 includes a first folding panel 33 and a second folding panel 34; the first side panel 21 extends along the length direction of the vehicle, and the first folding panel 33 is connected to the side of the first side panel 21 away from the top panel 10 to form a first shielding surface for the pressure relief valve, and the second side panel 22 extends along the width direction of the vehicle, and the second folding panel 34 is connected to the side of the second side panel 22 away from the top panel 10 to form a second shielding surface for the pressure relief valve; the first folding panel 33 can be folded toward the first side panel 21 to adjust the area of the first shielding surface, and the second folding panel 34 can be folded toward the second side panel 22 to adjust the area of the second shielding surface.
[0053] In practical applications, the pressure relief valve cover can usually include two plates, a first side plate 21 and a second side plate 22, which are vertically connected. The first side plate 21 extends along the length direction of the vehicle, so that the airflow in the vehicle can be discharged backward along the length direction of the vehicle, avoiding the gas in the vehicle from being transmitted to the front end of the vehicle and affecting the passengers in the vehicle. The second side plate 22 extends along the width direction of the vehicle, and the top plate 10 is connected to the top of the first side plate 21 and the second side plate 22, and the first side plate 21 and the second side plate 22 also extend along the height direction of the vehicle. In this way, the top plate 10 is used to seal the upper part of the pressure relief valve cover, so that the airflow in the vehicle can be discharged downward along the height direction of the vehicle, avoiding the gas in the vehicle from being transmitted to the upper part of the vehicle and affecting the passengers in the vehicle.
[0054] In the embodiment of the present application, the first folding plate 33 is connected to the first side panel 21, and the first folding plate 33 can be folded toward the first side panel 21. Specifically, different areas of the first folding plate 33 can be folded onto the first side panel 21 to adjust the first shielding surface. The second folding plate 34 is connected to the second side panel 22, and the second folding plate 34 can be folded toward the second side panel 22. Specifically, different areas of the second folding plate 34 can be folded onto the second side panel 22 to adjust the second shielding surface. Moreover, the folding areas of the first folding plate 33 and the second folding plate 34 can be the same or different, thereby realizing a variety of different adjustment methods of the pressure relief valve cover to the shielding surface of the pressure relief valve, and thus testing to obtain a folding scheme that makes the vehicle's NVH performance and ear pressure performance better.
[0055] For example, in the embodiment of the present application, the first folding plate 33 is provided with three folding portions 32, one of which can be folded on the first side plate 21, or two of which can be folded on the first side plate 21. Figure 2 As shown; three folding portions 32 may also be provided, all of which are folded on the first side plate 21, such as Figure 1 The first folding plate 33 may also be arranged not to be folded, such as Figure 3 As shown. Thus, the first folding plate 33 and the side plate 20 can form folding solutions with four different areas of the first shielding surface. Similarly, the second folding plate 34 also has three folding portions 32, one of which can be folded on the second side plate 22, or two of which can be folded on the second side plate 22, as shown. Figure 2 It is also possible to set three folding portions 32 are folded on the second side plate 22, such as Figure 1 The second folding plate 34 may also be provided without folding, such as Figure 3 As shown. Thus, the second folding plate 34 and the side plate 20 can form a folding scheme with four second shielding surfaces of different areas. In addition, the first folding plate 33 combined with the second folding plate 34 can have 16 different states, so that the pressure relief valve cover can be selected in the actual vehicle stage.
[0056] Optionally, in the embodiment of the present application, the folding plate 30 is provided with a first clamping portion 35, and the side plate 20 is provided with a second clamping portion 25; when the folding plate 30 is folded toward the side plate 20, the first clamping portion 35 is clamped to the second clamping portion 25. In this way, by clamping the first clamping portion 35 of the folding plate 30 to the second clamping portion 25 of the side plate 20, the folding plate 30 is more stably connected to the side plate 20 in the folded state, thereby improving the connection reliability between the folding plate 30 and the side plate 20, and preventing the folding plate 30 from being easily separated from the side plate 20 and being unstable after being folded. In addition, the first clamping portion 35 and the second clamping portion 25 can realize a detachable connection between the folding plate 30 and the side plate 20, which is convenient for adjustment, and has a simple structure and convenient operation.
[0057] For example, in the embodiment of the present application, the number of the first clamping parts 35 can include multiple, the number of the second clamping parts 25 can also include multiple, and the multiple first clamping parts 35 are respectively clamped to the second clamping parts 25, and one first clamping part 35 is correspondingly clamped to one second clamping part 25, forming multiple clamping positions. In this way, the connection stability between the folding plate 30 and the side plate 20 is further improved through the multiple clamping positions.
[0058] In the embodiment of the present application, optionally, the number of the second clamping parts 25 includes multiple, and the multiple second clamping parts 25 are arranged at intervals along the direction from the folding plate 30 to the side plate 20. In this way, through the multiple second clamping parts 25 distributed along the direction from the folding plate 30 to the side plate 20, the first clamping part 35 can be clamped to the second clamping parts 25 at different positions, thereby realizing the adjustment of the folding area of the folding plate 30.
[0059] In an optional embodiment of the present application, the first clamping portion 35 is a clamping hole, and the second clamping portion 25 is a protruding clamping block; when the folding plate 30 is folded toward the side plate 20, the clamping hole of the folding plate 30 is clamped to the clamping block of the side plate 20. In this way, the clamping hole can be sleeved and clamped to the outer periphery of the clamping block, so as to achieve a relatively stable clamping connection between the folding plate 30 and the side plate 20.
[0060] In another optional embodiment of the present application, the first clamping portion 35 is a protruding clamping block, and the second clamping portion 25 is a clamping hole; when the folding plate 30 is folded toward the side plate 20, the clamping block of the folding plate 30 is clamped into the clamping hole of the side plate 20. In this way, the clamping block can be embedded and clamped into the clamping hole, so as to achieve a relatively stable clamping connection between the folding plate 30 and the side plate 20.

In this way, the folding part can be folded according to actual needs, for example, the folding part can be completely folded to the side plate, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is smaller, or the folding part can be partially folded to the side plate, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is smaller, and the folding part can also be left folded, so that the pressure relief valve cover has the largest shielding surface area for the pressure relief valve. By adjusting the area of the folding plate folded to the side plate, the area of the shielding surface of the pressure relief valve cover to the pressure relief valve can be flexibly adjusted. Therefore, according to the actual situation of the later vehicle, by adjusting the area of the shielding surface of the pressure relief valve, the vehicle can have both good NVH performance and ear pressure performance. It avoids the large deviation between the shielding effect of the pressure relief valve cover of the actual vehicle on the pressure relief valve and the previous simulation state, so that the actual state of the vehicle has good NVH performance and ear pressure performance, and there is no need to re-open the mold of the pressure relief valve cover, thereby improving production efficiency.

Specifically, the folding plate is connected to the side plate, the side plate and the folding plate can jointly form the shielding surface for the pressure relief valve, and the folding plate can be folded toward the side plate by folding, so that the area of the shielding surface of the folding plate for the pressure relief valve can be changed, thereby adjusting the area of the shielding surface of the pressure relief valve by folding the folding portion toward the side plate. In this way, the folding part can be folded according to actual needs, for example, the folding part can be completely folded to the side plate, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is smaller, or the folding part can be partially folded to the side plate, so that the area of the shielding surface of the pressure relief valve cover to the pressure relief valve is smaller, and the folding part can also be left folded, so that the pressure relief valve cover has the largest shielding surface area for the pressure relief valve. By adjusting the area of the folding plate folded to the side plate, the area of the shielding surface of the pressure relief valve cover to the pressure relief valve can be flexibly adjusted. Therefore, according to the actual situation of the later vehicle, by adjusting the area of the shielding surface of the pressure relief valve, the vehicle can have both good NVH performance and ear pressure performance. It avoids the large deviation between the shielding effect of the pressure relief valve cover of the actual vehicle on the pressure relief valve and the previous simulation state, so that the actual state of the vehicle has good NVH performance and ear pressure performance, and there is no need to re-open the mold of the pressure relief valve cover, thereby improving production efficiency.
