Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle structure, in particular to a rear bumper bracket structure and a vehicle. BACKGROUND

[0002] In order to balance the air pressure inside and outside the vehicle, a pressure relief valve is designed on the automobile. The exhaust port of the pressure relief valve is arranged downward. The sealing blade thereof can cover the exhaust port under the action of gravity, and open when the door is closed or the air inlet of the air conditioner is opened for outside circulation, thereby reducing the discomfort of the passengers caused by the pressure difference between the inside and outside of the vehicle. However, when the automobile is running at high speed, the sealing blade of the pressure relief valve will change from the closed sealing state to the open state under the action of the pressure difference between the inside and outside of the vehicle, causing the outside noise such as wind noise and tire noise to enter the vehicle through the unsealed blade of the pressure relief valve, increasing the noise in the vehicle and affecting the comfort experience of the passengers.

[0003] To this end, the prior art usually increases the loss of transmission of outside noise by designing an acoustic cover at the position of the pressure relief valve on the inside of the vehicle to reduce the noise in the vehicle, or cuts off the air transmission path of the noise by controlling the opening and closing of the pressure relief valve through an electric component. However, the above-mentioned first method needs to be integrally formed with the acoustic cover and the pressure relief valve to effectively absorb the noise, and the above-mentioned second method needs to integrate corresponding control components, power supply devices and control systems to achieve specific effects by opening and closing control under different working conditions. However, the installation space of the acoustic cover or the electric component at the pressure relief valve requires a higher space, which not only increases the structural complexity of the pressure relief valve, but also greatly increases the production cost of the pressure relief valve.

[0030] Moreover, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the

[0031] The application will be further described with reference to the drawings and specific examples. It is to be understood that the technical features involved in the various embodiments of the application described below can be combined with each other as long as there is no conflict. The embodiments described below with reference to the drawings are exemplary and are intended to explain the application, but should not be understood as limiting the application.

[0032] As Figures 1 to 4As shown, the embodiment provides a rear bumper bracket structure, which is arranged between the body side wall 5 and the rear bumper 6, and can connect the rear bumper 6 to the body side wall 5. The rear bumper bracket structure comprises a bracket body 1, a first sealing member 2 and a second sealing member 3. The upper part of the bracket body 1 extends below the pressure relief port 51 of the body side wall 5, and a flow blocking part 11 corresponding to the lower profile of the pressure relief port 51 is arranged on the bracket body 1. The first sealing member 2 is fixedly connected to one side of the flow blocking part 11 close to the body side wall 5 by adhesion, and is adapted to block the gap between the flow blocking part 11 and the body side wall 5. The second sealing member 3 is fixedly connected to one side of the flow blocking part 11 close to the rear bumper 6 by adhesion, and is adapted to block the gap between the flow blocking part 11 and the rear bumper 6. In this way, the gaps between the flow blocking part 11 and the body side wall 5 and between the flow blocking part 11 and the rear bumper 6 are blocked by the first sealing member 2 and the second sealing member 3, and the lower side of the pressure relief port 51 is externally blocked by the flow blocking part 11, thereby cutting off the direct transmission path of the wind noise, tire noise and other external noises, effectively blocking the transmission of external noises to the vehicle interior, and achieving the purpose of improving the comfort of the vehicle occupants.

[0033] It can be understood that the pressure relief port 51 is a mounting port provided on the body side wall 5 for mounting the body pressure relief valve 7. The body pressure relief valve 7 can be mounted at the pressure relief port 51 by clamping to balance the air pressure inside and outside the vehicle. The exhaust port of the body pressure relief valve 7, which balances the air pressure inside and outside the vehicle, is usually arranged downward, so that the sealing blade can cover the exhaust port under the action of gravity and open under the impact of air pressure when the door is closed or the air conditioner is in use, thereby reducing the discomfort of the occupants caused by the pressure difference between the inside and outside of the vehicle. Therefore, the upper part of the bracket body 1 extends below the pressure relief port 51 of the body side wall 5, and the flow blocking part 11 corresponding to the lower profile of the pressure relief port 51 is arranged on the bracket body 1. The first sealing member 2 and the second sealing member 3 are arranged on the opposite outer sides of the flow blocking part 11, which can externally block the air flow inlet and outlet of the pressure relief port 51, thereby cutting off the direct transmission path of the wind noise, tire noise and other external noises, effectively blocking the transmission of external noises to the vehicle interior, and achieving the purpose of improving the comfort of the vehicle occupants.

[0034] In some embodiments, as Figures 1 to 3As shown, the side of the flow blocking part 11 close to the vehicle body side wall 5 is provided with a protruding edge 12, which extends along the length direction of the flow blocking part 11; the upper end surface of the protruding edge 12 is a first step surface 121, and the upper end surface of the flow blocking part 11 is a second step surface 111, the height of the first step surface 121 in the vehicle height direction is higher than the height of the second step surface 111; the first sealing member 2 is fixedly connected to the side of the protruding edge 12 close to the vehicle body side wall 5, and is adapted to block the gap between the protruding edge 12 and the vehicle body side wall 5. Through the setting of the protruding edge 12, installation space can be provided for the first sealing member 2, and effective connection of the first sealing member 2 between the bracket body 1 and the vehicle body side wall 5 is realized; at the same time, through the stepped design of the first step surface 121 and the second step surface 111, the smoothness and smoothness of the airflow discharge can be ensured, the convection impact of the pressure relief airflow discharged by the vehicle body pressure relief valve 7 when being discharged outward is reduced, and excessive noise is avoided.

[0035] In some embodiments, as shown in Figure 1 and Figure 2 the length direction ends of the protruding edge 12 are bent upwards to form a bent portion 122 along the lower contour of the pressure relief port 51, and the first sealing member 2 is shaped, i.e. the shape of the first sealing member 2 is adapted to the shape of the protruding edge 12. In this way, the bent portion 122 and the first sealing member 2 configured in shape can further improve the blocking effect between the bracket body 1 and the vehicle body side wall 5, and effectively improve the noise reduction performance of the overall structure.

[0036] Preferably, the length of the bent portion 122 bent upwards does not exceed one half of the side contour of the pressure relief port 51, i.e. one half of the height direction dimension of the pressure relief port 51, so that the amount of sealing material can be reduced while meeting the noise reduction function, and the space occupation of the noise reduction structure can be effectively reduced.

[0037] In some embodiments, as shown in Figures 1 to 3 the edge of the protruding edge 12 is formed with a flange 123 arranged in shape with the protruding edge 12, the length direction ends of the flange 123 are closed connected with the flow blocking part 11, and the first step surface 121 is defined on the upper end surface of the flange 123. Through the setting of the flange 123, the structural size of the protruding edge 12 can be ensured while meeting the condition of forming the first step surface 121 as a blocking surface on the lower side of the pressure relief port 51, and the amount of material can be further reduced to reduce the weight of the bracket.

[0038] In some embodiments, as shown in Figures 1 to 3As shown, the side of the flow blocking part 11 close to the rear bumper 6 is provided with a groove 13, which extends along the length direction of the flow blocking part 11; the upper end surface of the groove 13 is a third step surface 131, which is lower than the second step surface 111 in the vehicle height direction; the second sealing part 3 is fixedly connected to the groove 13 and is adapted to block the gap between the groove 13 and the rear bumper 6. Through the provision of the groove 13, installation space can be provided for the second sealing part 3, the installation gap between the bracket body 1 and the rear bumper 6 is shortened, and effective connection of the second sealing part 3 between the bracket body 1 and the rear bumper 6 is achieved.

[0039] In some embodiments, as shown in Figure 1 and Figure 3 the second sealing part 3 is conformal to the groove 13, i.e. the shape of the second sealing part 3 is adapted to the shape of the groove 13; and the upper end surface of the second sealing part 3 is flush with the second step surface 111. In this way, the second sealing part 3 can cooperate with the first step surface 121 and the second step surface 111 to ensure the smoothness and smoothness of the airflow discharge, reduce the convection effect generated by the airflow discharged by the vehicle body pressure relief valve 7 when discharging pressure, and further avoid generating excess noise.

[0040] In some embodiments, as shown in Figure 1 and Figure 2 the lower part of the bracket body 1 is configured as a frame structure 14, which includes a plurality of edge beams 141 and at least one connecting beam 142; the plurality of edge beams 141 are connected end to end to enclose the outer contour of the frame structure 14; the at least one connecting beam 142 is located inside the frame structure 14 and has its length direction ends respectively connected to the opposite inner sides of two edge beams 141, which can provide inner side support and torque transmission for the two side edge beams 141, thereby effectively improving the rigidity and stability of the overall structure; the edge beams 141 and / or the connecting beams 142 are provided with a plurality of mounting holes 143 for connecting the vehicle body side wall 5 or the rear bumper 6, which are preferably provided at the end portions of the edge beams 141 and / or the connecting beams 142; in this way, by passing the bolts through the mounting holes 143 and connecting to the vehicle body side wall 5 or the rear bumper 6, the bracket body 1 is fixedly connected to the vehicle body side wall 5 or the rear bumper 6. By configuring the lower part of the bracket body 1 as a frame structure 14, the material weight can be reduced while ensuring the bracket installation rigidity, thereby achieving lightweight.

[0041] For example, as shown in Figure 1 and Figure 2As shown, in the embodiment, the frame structure 14 includes four edge beams 141 and one connecting beam 142, which are integrally configured as a "day" shaped structure, which can effectively improve the structural strength of the bracket body 1 and meet the positioning design of the plurality of mounting holes 143. In other embodiments, the frame structure 14 can also be combined into other shapes such as "eye" shape, which will not be described here.

[0042] It can be understood that the bracket body 1 including the flow blocking part 11 and the frame structure 14 can be an injection molded part integrally injection molded, which can further reduce the material weight without affecting the bracket mounting stiffness.

[0043] In some embodiments, as shown in Figure 1 and Figure 4 As shown, the rear bumper bracket structure further includes a fixing plate 4, which includes a first connecting part 41 and a second connecting part 42 distributed above and below and connected to each other, wherein the first connecting part 41 is a wave-shaped structure extending along the length direction of the vehicle, and the wave shape is a ladder-shaped wave or a rectangular wave alternately formed, and is adapted to be fixedly connected to the lower end of the vehicle body side wall 5, and the fixed connection manner includes but is not limited to welding and the like; the second connecting part 42 is a boss structure with a convex shape in the middle and a turned-up shape around the periphery, and the convex surface faces the frame structure 14 and can be fixedly connected to the frame structure 14 of the bracket body 1 through bolts. Since the bracket body 1 needs to reserve the installation gap of the first seal 2 and the second seal 3, the upper part of the bracket body 1 is spaced apart from the vehicle body side wall 5, so that the lower part of the bracket body 1, i.e. the frame structure 14, is suspended from the vehicle body side wall 5. In this way, through the arrangement of the fixing plate 4, the lower part of the bracket body 1, i.e. the frame structure 14, can be effectively connected to the vehicle body side wall 5, thereby improving the connection stability between the bracket body 1 and the vehicle body side wall 5. The wave-shaped structure of the first connecting part 41 can improve the structural strength of the fixing plate 4 and ensure the effective contact area between the fixing plate 4 and the vehicle body side wall 5, thereby stably connecting the fixing plate 4 and the vehicle body side wall 5. At the same time, the boss structure of the second connecting part 42 can effectively improve the structural stiffness of the fixing plate 4, thereby improving the support strength of the mounting point and ensuring the connection stability between the fixing plate 4 and the frame structure 14.
