[0002] The pressure relief valve is installed on the vehicle body and is usually opened when the door is closed to balance the air pressure inside the vehicle, thereby reducing the increase in ear pressure of users inside the vehicle when the door is closed. The rear bumper bracket of the vehicle (in order to assemble the rear bumper and the side panel together) is usually arranged on the outside of the pressure relief valve, and a baffle is set on the rear bumper bracket below the pressure relief valve. When the vehicle is wading, it can prevent water from surging upward and prevent water from flowing into the vehicle through the pressure relief valve. However, the baffle also hinders the normal exhaust of the pressure relief valve. The air resistance of the vehicle when the door is closed is too large, causing discomfort to the passengers' ears and a poor user experience. Summary of the invention

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0029] The technical solution of the present application is described in detail below with reference to the accompanying drawings.
[0030] like Figure 1 and Figure 2 As shown, the rear protection bracket 100 of the embodiment of the present invention includes a bracket body 1, a first baffle 2 and a partition 3. The bracket body 1 has a top end 101 and a bottom end 102 opposite to each other in the vertical direction, the first baffle 2 is arranged on one side of the bracket body 1 in the thickness direction, and the first baffle 2 extends along a first horizontal direction, which is consistent with the front and rear direction of the vehicle.
[0031] The partition 3 is arranged on at least one end of the first baffle 2 in its extension direction. The first baffle 2 is arranged at an angle with the partition 3. The first baffle 2 divides the partition 3 into a first plate body 301 and a second plate body 302. The first plate body 301 is arranged adjacent to the top end 101 of the bracket body 1, and an air hole 3011 is provided on the first plate body 301.
[0032] The partition 3 is arranged on at least one end of the first baffle 2 in its extension direction. It can be understood that the partition 3 can be only arranged at the front end of the first baffle 2; or the partition 3 is only arranged at the rear end of the first baffle 2; or the partition 3 can also be arranged at the front and rear ends of the first baffle 2.
[0033] When the rear protection bracket 100 of the embodiment of the present invention is installed on the vehicle, the first baffle 2 of the rear protection bracket 100 is located below the pressure relief valve 200, and the partition 3 is located on the side of the pressure relief valve 200. When the door of the vehicle is closed, the internal pressure of the vehicle increases, the pressure relief valve 200 opens, and the airflow discharged by the pressure relief valve 200 flows toward the bracket body 1. At this time, a high-pressure area is formed between the first baffle 2, the bracket body 1 and the first plate body 301, and the airflow in the high-pressure area flows to the side of the partition 3 away from the pressure relief valve 200 in the thickness direction through the air hole 3011 on the first plate body 301, and a medium-pressure area is formed between the partition 3 and the bracket body 1. The airflow in the medium-pressure area flows to the area formed between the first baffle 2, the second plate body 302 and the bracket body 1 through the side edge of the second plate body 302, which is a low-pressure area. When the airflow in the high-pressure area flows to the medium-pressure area through the edge of the first plate body 301, a forward vortex is formed. When the airflow in the medium-pressure area flows to the low-pressure area through the edge of the second plate body 302, a reverse vortex is formed. The forward vortex and the reverse vortex cancel each other out, which greatly reduces the size of the air resistance when the pressure relief valve 200 is exhausted, thereby greatly reducing the size of the air resistance when closing the door, which can greatly reduce or even avoid the discomfort of the passengers' ear pressure when closing the car door, thus providing a good user experience and other advantages.
[0034] Therefore, the rear protection bracket 100 according to the embodiment of the present invention has advantages such as good user experience.
[0035] In addition, the first plate body 301 of the partition 3 can also block the water flow when the vehicle is wading, preventing the water flow from flowing into the pressure relief valve 200 through the side of the first baffle 2, which can reduce the air resistance of closing the door and improve the waterproof effect.
[0036] In some embodiments, in the thickness direction of the bracket body 1 , the first baffle 2 is disposed away from the protruding partition 3 at one end of the bracket body 1 .
[0037] like Figure 2 As shown, the rear protection bracket 100 of the embodiment of the present invention is provided with the first baffle plate 2 protruding from the baffle plate 3 at one end of the bracket body 1 in the thickness direction of the bracket body 1, which is conducive to the airflow in the high-pressure area formed between the first baffle plate 2, the bracket body 1 and the first plate body 301 to flow smoothly to the medium-pressure area through the edge of the first plate body 301, so as to form a positive vortex quickly, and avoid blocking the formation of the positive vortex due to the large width of the baffle plate 3. Similarly, it is also conducive to the airflow in the medium-pressure area formed between the baffle plate 3 and the bracket body 1 to flow to the low-pressure area through the edge of the second plate body 302, so as to form a reverse vortex quickly, so that the reverse vortex and the forward vortex are quickly formed and offset in time, so as to quickly reduce the air resistance of closing the door and improve the user experience.
[0038] Preferably, the first baffle plate 2 and the partition plate 3 are arranged at an angle of 90°.
[0039] like Figure 1 and Figure 2 As shown, the rear protection bracket 100 of the embodiment of the present invention sets the first baffle 2 and the partition 3 at an angle of 90°, so that the high-pressure vortex formed between the high-pressure area and the medium-pressure area is located directly above the low-pressure vortex formed by the middle sub-area and the low-pressure area. Under the action of gravity, the forward vortex can move downward quickly to meet and offset the reverse vortex, which is beneficial to improve the offset effect of the forward vortex and the reverse vortex.
[0040] In some embodiments, the first plate 301 and the second plate 302 have the same height.
[0041] like Figure 1 and Figure 2 As shown, the rear protection bracket 100 of the embodiment of the present invention sets the height of the first plate 301 and the second plate 302 to be the same, so that the size of the forward vortex of the airflow flowing from the high-pressure area to the medium-pressure area is equivalent to the size of the reverse vortex of the airflow flowing from the medium-pressure area to the low-pressure area, so that the forward vortex and the reverse vortex can achieve maximum offsetting effect, thereby minimizing the closing air resistance.
[0042] In some embodiments, the air hole 3011 is disposed adjacent to the first baffle 2 in the vertical direction.
[0043] like Figure 1 and Figure 2 As shown, the rear protection bracket 100 of the embodiment of the present invention sets the air hole 3011 adjacent to the first baffle 2. When the pressure relief valve 200 releases pressure and exhausts air to the high-pressure area, the airflow in the high-pressure area can quickly flow to the low-pressure area through the air hole 3011, and quickly diffuse from the middle position of the low-pressure area to the upper and lower ends, which is beneficial to increase the diffusion speed of the airflow in the medium-pressure area, accelerate the formation of the forward vortex between the high-pressure area and the medium-pressure area and the formation of the reverse vortex between the medium-pressure area and the low-pressure area, and is beneficial to quickly reduce the air resistance when closing the door.
[0044] Optionally, there are multiple air holes 3011 , and the multiple air holes 3011 are arranged in a matrix.
[0045] like Figure 2 As shown, since there are multiple air holes 3011 and they are arranged in a matrix, when the airflow in the high-pressure area flows to the medium-pressure area through the multiple air holes 3011, the airflow distribution in the medium-pressure area is more uniform, the intensity of the multiple forward vortices formed between the high-pressure area and the medium-pressure area is relatively uniform and stable, and the intensity of the multiple reverse vortices formed between the medium-pressure area and the low-pressure area is also relatively uniform and stable, which is conducive to the maximum offset of the forward vortex and the reverse vortex, avoiding poor offset effect due to poor stability of the forward vortex and the reverse vortex.
[0046] In some embodiments, the top surface of the first baffle plate 2 has a plurality of recesses 201 , and the plurality of recesses 201 are arranged at intervals along the extension direction of the first baffle plate 2 .
[0047] like Figure 1 and Figure 2 As shown, when the airflow discharged from the pressure relief valve 200 passes through the recess 201 on the first baffle 2, the airflow enters the recess 201 and generates a counter-rotating airflow in the recess 201, which delays the separation of the airflow. The low-speed rotating airflow in the recess 201 and the high-speed airflow outside the recess 201 produce air-air contact to form a vortex pad effect, so that the friction between the low-speed rotating airflow in the recess 201 and the high-speed airflow outside the recess 201 is rolling friction, thereby greatly reducing the airflow resistance flowing through the first baffle 2, which is further beneficial to reducing the air resistance when closing the door.
[0048] Alternatively, if Figure 1 and Figure 2 As shown, a plurality of recesses 201 are arranged in a matrix, so that the recesses 201 are distributed more evenly on the first baffle 2, so that the airflow inside the recesses 201 and the airflow flow characteristics outside the recesses 201 are relatively stable, which is beneficial to the intensity of smaller turbulent bursts, thereby reducing the loss of turbulent kinetic energy, and is beneficial to further reduce frictional resistance to reduce closing air resistance.
[0049] In some embodiments, the distance between two adjacent recesses 201 is 2 mm-10 mm.
[0050] For example, the distance between two adjacent recesses 201 is 2 mm, 5 mm, 8 mm or 10 mm. Preferably, it is 5 mm. Figure 1 and Figure 2 As shown, when the distance between two adjacent recesses 201 is set too small (for example, 1 mm) or too large (for example, 15 mm), the airflow flow characteristics inside the recess 201 and the airflow flow characteristics outside the recess 201 are relatively unstable, which is not conducive to the intensity of smaller turbulent bursts, and will lead to a large loss of turbulent kinetic energy, which is not conducive to reducing the friction resistance of the airflow, and is not conducive to reducing the air resistance effect.
[0051] In some embodiments, the outer peripheral contour of the cross section of the recess 201 is circular, and the opening diameter of the recess 201 is 1.5 mm-3 mm.
[0052] For example, the opening diameter of the recess 201 is 1.5 mm, 2 mm or 3 mm. Preferably, it is 2 mm. Figure 2As shown, if the opening size of the recess 201 is set too small (for example, 0.5 mm) or too large (for example, 5 mm), the airflow flow characteristics inside the recess 201 and the airflow flow characteristics outside the recess 201 are relatively unstable, which is not conducive to the intensity of smaller turbulent bursts, and will lead to a large loss of turbulent kinetic energy, which is not conducive to reducing the friction resistance of the airflow, and is not conducive to reducing the air resistance effect.
[0053] In some embodiments, the rear protection bracket 100 of the embodiment of the present invention also includes a second baffle 4, which is arranged on one side of the bracket body 1 in its thickness direction, and the second baffle 4 extends along the first horizontal direction. The second baffle 4 and the partition 3 are arranged at intervals in the vertical direction, and an accommodating space 5 is defined between the first baffle 2, the second baffle 4 and the partition 3, and the accommodating space 5 is used to accommodate the pressure relief valve 200.
[0054] like Figure 1 and Figure 2 As shown, during installation, the pressure relief port of the pressure relief valve 200 is placed in the accommodating space 5. After the pressure relief valve 200 releases pressure and exhausts air, the second baffle 4 can block the airflow from flowing upward, so that the airflow flows downward and flows toward the partition 3 set at the front and rear ends of the first baffle 2, so that as many airflow resistances as possible can be weakened through the partition 3, which is further beneficial to reducing the air resistance when closing the door.
[0055] The vehicle body assembly of the embodiment of the present invention includes a side panel, a pressure relief valve 200 and a rear guard bracket 100, the pressure relief valve 200 is arranged on the side panel, the rear guard bracket is the rear guard bracket 100 described in any of the above embodiments, the rear guard bracket 100 is connected to the side panel, the pressure relief valve 200 is arranged between the side panel and the bracket body 1, and the first baffle 2 is located below the pressure relief valve 200.
