A vehicle body assembly and vehicle

Abstract

The application discloses a vehicle body assembly and a vehicle. The vehicle body assembly comprises a bumper shell and a valve body assembly. The bumper shell is formed with an air flow channel, an air inlet and an air outlet of the air flow channel. The air inlet is directed towards the inside of the vehicle, and the air outlet is directed towards the outside of the vehicle. The valve body assembly is located on the side of the bumper shell directed towards the inside of the vehicle. The valve body assembly comprises a guide plate and a valve body frame. The valve body frame is connected with the bumper shell. The guide plate is connected with the valve body frame. The guide plate is switched from a first state to a second state under the action of the air flow in the inside of the vehicle. In the first state, the guide plate blocks the air inlet. In the second state, the guide plate opens the air inlet. Thus, the air flow channel can be connected with the inside and the outside of the vehicle. When the air pressure in the inside of the vehicle is greater than the air pressure in the outside of the vehicle during the driving of the vehicle, the guide plate is opened, the air flow in the inside of the vehicle enters the air flow channel through the air inlet, and then flows out of the air outlet and is discharged to the outside of the vehicle. Meanwhile, the air flow channel can also isolate the noise generated by the wheels and the electric drive from directly entering the inside of the vehicle.

[0002] With the development of the automotive industry, NVH performance has received increasing attention. The pressure relief valve on the car bumper opens while driving, creating a path for electric drive whistling and tire noise to be transmitted into the car.

[0003] In the existing technology, acoustic wrapping of the electric drive body has the problems of long development cycle and high cost. Moreover, the openings and avoidance caused by the connectors make it difficult to wrap tightly, thus limiting the noise reduction effect. While optimizing the acoustic wrapping of the rear side of the vehicle can effectively improve noise, it will affect the depressurization airflow and door closing force. Utility Model Content

[0004] The main objective of this application is to provide a vehicle body assembly and a vehicle that address the aforementioned technical problems existing in the prior art.

The valve body assembly is located on the side of the bumper housing facing the interior of the vehicle. The valve body assembly includes a deflector and a valve body frame. The valve body frame is connected to the bumper housing, and the deflector is connected to the valve body frame. The deflector switches from a first state to a second state under the influence of airflow inside the vehicle. In the first state, the deflector blocks the air inlet, and in the second state, it opens the air inlet.

[0006] In some embodiments, the valve body assembly includes a limiting block connected to the valve body frame and the guide plate, the limiting block being used to limit the guide plate during the process of the guide plate switching from the first state to the second state.

[0007] In some embodiments, the guide plate extends along a first direction, the airflow acts on the guide plate along a second direction perpendicular to the first direction, and there are multiple limiting blocks, which are spaced apart along the first direction.

[0008] In some embodiments, the end of the deflector away from the limiting block is tilted outward relative to the end near the limiting block.

[0009] In some embodiments, the valve body assembly includes a flow guide shield connected to the valve body frame on the side opposite to the bumper housing, and the flow guide shield is provided with a flow guide slot.

[0014] To address the aforementioned problems, this application provides a vehicle that includes the body components described above.

[0015] Compared with existing technologies, the vehicle body assembly of this application includes a bumper housing and a valve body assembly. The bumper housing forms an airflow channel with an inlet and an outlet. The inlet faces the interior of the vehicle, and the outlet faces the exterior. The valve body assembly is located on the side of the bumper housing facing the interior. The valve body assembly includes a deflector and a valve body frame. The valve body frame is connected to the bumper housing, and the deflector and the valve body frame are connected. The deflector switches from a first state to a second state under the action of airflow inside the vehicle. In the first state, the deflector blocks the inlet, and in the second state, it opens the inlet. Through the above implementation, the airflow channel can connect the interior and exterior of the vehicle. When the air pressure inside the vehicle is greater than the air pressure outside the vehicle during driving, the deflector opens, allowing airflow from inside the vehicle to enter the airflow channel through the inlet and then exit through the outlet to the exterior. At the same time, the airflow channel can also isolate noise generated by the wheels and electric drive from reaching the interior of the vehicle. Attached Figure Description

[0032] As a key pillar industry globally, the automotive industry's development level profoundly influences modern society's travel patterns and economic structure. With the continuous increase in market share and the expanding base of private car users, the automotive industry has entered a new stage where large-scale production and personalization coexist. This trend has had a significant pulling effect on the upstream automotive parts industry, directly driving its manufacturing processes and R&D design systems to iterate and upgrade towards greater efficiency and precision.

[0033] As an important component of automobiles, the body assembly 10 includes a bumper housing 100 and a valve body assembly 200. In existing technical solutions, the noise generated by the vehicle tires and electric drive will directly enter the vehicle interior. Usually, sound-absorbing cotton is used to wrap the motor, but this has a long development cycle and high cost. In addition, there are many openings on the electric drive, which makes it difficult to seal the wrapping. The noise isolation cannot meet the requirements of various aspects.

[0034] To address the technical problems existing in related technologies, this application provides a vehicle body component 10, see [link to relevant documentation]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an embodiment of the vehicle body component provided in this application. Figure 2 This is a schematic diagram of an embodiment of the bumper housing provided in this application.

[0035] The vehicle includes a body component 10, which serves as part of the vehicle's body structure. The bumper housing 100 within the body component 10 provides protection for the vehicle. The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle representing a technological trend. New energy vehicles mainly include pure electric vehicles, hybrid electric vehicles, and range-extended electric vehicles. One of the core technological features of new energy vehicles lies in the construction of the power battery system. The battery system not only serves as the high-voltage energy source for the drive motor but also constitutes the core power supply platform in the vehicle's electrical architecture. It is responsible for providing continuous and stable electrical energy to the vehicle's drive system, electronic control unit, and various auxiliary equipment, serving as an indispensable energy foundation and control center for the normal operation of the entire vehicle. When a collision occurs, the bumper housing 100 absorbs and disperses the impact energy through its own deformation or energy-absorbing structure, thereby minimizing damage to the vehicle's body structure and internal core components, effectively reducing maintenance costs.

Figure 4 This is a schematic diagram of the internal structure of an embodiment of the airflow channel provided in this application. Figure 5 This is a first-view structural schematic diagram of an embodiment of the valve body assembly provided in this application. Figure 6 This is a second-view structural schematic diagram of an embodiment of the valve body assembly provided in this application.

[0037] The body assembly 10 includes a bumper housing 100 and a valve body assembly 200. The bumper housing 100 forms an airflow channel 110 with an air inlet 111 and an air outlet 310. The air inlet 111 faces the interior of the vehicle, and the air outlet 310 faces the exterior of the vehicle. The valve body assembly 200 is located on the side of the bumper housing 100 facing the interior of the vehicle. The valve body assembly 200 includes a deflector 210 and a valve body frame 220. The valve body frame 220 is connected to the bumper housing 100, and the deflector 210 is connected to the valve body frame 220. Under the action of the airflow inside the vehicle, the deflector 210 switches from a first state to a second state. In the first state, the deflector 210 blocks the air inlet 111, and in the second state, it opens the air inlet 111.

[0038] The bumper housing 100 is connected to the rear of the vehicle via a connecting plate on the inside of the vehicle, forming an airflow channel 110 on the bumper housing 100 facing inwards towards the vehicle interior. The rear of the bumper housing 100 is the rear of the vehicle. This airflow channel 110 also serves as a path for the exchange of media between the vehicle's interior and the external environment; this media can be airflow or noise. On the side of the bumper housing 100, one end of the airflow channel 110 faces inwards towards the vehicle interior and is connected to the valve body assembly 200. The other end faces outwards towards the vehicle exterior and is located on the front of the bumper housing 100, with the side of the bumper housing 100 representing the side of the vehicle and the front of the bumper housing 100 representing the rear of the vehicle. Therefore, the airflow channel 110 is located at the bend of the bumper housing 100, and the internal channel has an irregular shape. It generally presents a downward channel direction. That is, in the vertical direction of the vehicle, the air inlet 111 of the airflow channel 110 is higher than the air outlet 310. The specific shape design of the airflow channel 110 can be selected according to the actual position on the bumper housing 100.

[0039] The valve body assembly 200, located on the bumper housing 100, includes a baffle 210 and a valve body frame 220. The valve body frame 220 is connected to the air intake 111 facing the airflow passage 110 inside the vehicle. The baffle 210 is connected to the valve body frame 220 and can switch states. The shape of the frame structure can be selected according to the actual situation of the air intake 111, and can be a closed annular structure, forming a frame body that mainly supports the baffle 210. The connection method of the deflector 210 is not fixed, so as to realize the switching of states. When the vehicle is stationary, the deflector 210 is located on the valve body frame 220 to block the air intake 111, which is the first state. During the vehicle movement, the deflector 210 will rotate to open the air intake 111, which is the second state. The actions of the deflector 210 in the state switching include, but are not limited to, rotation, translation, flipping or a combination of these movements, as long as the air intake 111 can be opened. At the same time, the deflector 210 is connected to the valve body frame 220, and the state switching can be realized by hinge, elastic deformation or sliding rail.

[0040] Specifically, when the vehicle is stationary, the air pressure inside and outside the vehicle is the same, and the deflector 210 is in a stationary first state, blocking the air intake 111 of the airflow channel 110. When the vehicle is moving, the air pressure inside the vehicle is higher than that outside. This pressure difference causes the deflector 210 to switch from the first state of blocking the air intake 111 to the second state of opening the air intake 111, thus allowing the airflow inside the vehicle to be discharged to the outside through the airflow channel 110. Furthermore, since the wheels and motor are close to the valve body assembly 200, the airflow channel 110 can discharge the noise generated during vehicle operation to the outside, thereby isolating the wheel and electric drive noise from directly reaching the vehicle interior. Additionally, the bumper housing 100 is extensively covered with sound-absorbing cotton on the side inside the vehicle, effectively weakening the noise generated by the motor drive that is transmitted into the vehicle interior. Secondly, the height of the airflow channel 110 also makes it easier for the airflow inside the vehicle to enter through the air inlet 111 and exit through the air outlet 310. The fact that the air inlet 111 is higher than the air outlet 310 can effectively prevent the airflow from flowing back into the vehicle.

[0041] Furthermore, the valve body assembly 200 includes a limiting block 230, which is connected to the valve body frame 220 and the guide plate 210. The limiting block 230 is used to limit the guide plate 210 during the process of switching the guide plate 210 from the first state to the second state.

[0042] To enable the switching of the state of the deflector 210, a limit block 230 is provided on the valve body assembly 200. The limit block 230 is located away from the vehicle interior and is movably connected to the deflector 210 and the valve body frame 220. That is, the connection state of the limit block 230 can change according to different situations, and its specific situation changes accordingly based on the state switching of the deflector 210.

[0043] Furthermore, the guide plate 210 extends along the first direction X, and the airflow acts on the guide plate 210 along the second direction Y perpendicular to the first direction X. There are multiple limiting blocks 230, and the multiple limiting blocks 230 are spaced apart along the first direction X.

[0044] Specifically, the deflector 210 is fixed to the valve body frame 220 and located on the side rear of the bumper housing 100. It is configured as a plate-like structure extending along the first direction X, with the end of the deflector 210 near the top of the vehicle connected to the valve body frame 220. There is at least one deflector 210, and multiple deflectors 210 are spaced apart along the second direction Y, where the second direction Y is the vertical direction of the vehicle. When the vehicle is stationary, the multiple deflectors 210 are in their natural state, used to block the air intake 111. During vehicle operation, a pressure difference is generated inside and outside the vehicle, and the airflow inside the vehicle acts on the deflector 210 along the second direction Y. Because the end of the deflector 210 near the top of the vehicle is connected to but not fixed to the valve body frame 220, and the other ends are not fixed, the airflow acting on the deflector 210 causes the deflector 210 to switch states, i.e., the deflector 210 switches from blocking the air intake 111 to allowing air to pass through the air intake 111.

[0045] Furthermore, the end of the deflector 210 furthest from the limiting block 230 is tilted outward relative to the end closest to the limiting block 230. Specifically, when the vehicle is in motion, the air pressure inside the vehicle is greater than the air pressure outside, and the airflow channel 110 connects the inside and outside of the vehicle. The airflow inside the vehicle acts on the deflector 210, causing it to tilt. The end of the deflector 210 near the top of the vehicle is rotatably connected to the valve body frame 220. When the airflow acts perpendicularly on the deflector 210, it causes the end of the deflector 210 near the bottom of the vehicle to tilt, with the tilt direction closer to the outside of the vehicle. At this time, the tilt of the deflector 210 opens the air intake 111, and the airflow inside the vehicle causes the deflector 210 to tilt outward, thus entering the airflow channel 110 and being discharged through the air outlet 310.

[0046] Furthermore, the valve body assembly 200 includes a flow guide 240, which is connected to the valve body frame 220 on the side opposite to the bumper housing 100, and the flow guide 240 is provided with a flow guide slot 241.

[0047] Specifically, a flow guide shroud 240 with a flow guiding and protective structure is provided on the air inlet 111 end of the valve body assembly 200. The flow guide shroud 240 is connected to the valve body frame 220 and located between the valve body frame 220 and the vehicle interior space. The structure of the flow guide shroud 240 may include, but is not limited to, a shell type, which may be a cover that partially surrounds the valve body assembly 200, and has one or more flow guide slots 241 opened on the cover. Preferably, the flow guide shroud 240 has one flow guide slot 241. The connection between the flow guide shroud 240 and the valve body frame 220 may be detachable or non-detachable, including threaded connection, snap-fit ​​connection, welding, riveting, etc. Preferably, the fairing 240 is located on a portion of the valve body frame 220 near the upper part of the vehicle. The fairing 240 is fitted onto this portion of the valve body frame 220 to reduce the area of ​​the air outlet 310. When airflow exists in the airflow channel 110, it effectively prevents the airflow in the airflow channel 110 from flowing back into the vehicle interior. Simultaneously, sound-absorbing cotton is provided on the side of the fairing 240 near the valve body frame 220, which further prevents external noise from being transmitted into the vehicle interior.

[0048] Furthermore, the valve body assembly 200 includes a seal 250 disposed around the valve body assembly 200. The shape and size of the seal 250 are configured according to the frame structure of the valve body assembly 200, and the seal 250 is sealed around the valve body assembly 200 to prevent gaps between the valve body assembly 200 and the vehicle interior, thereby preventing airflow or noise from being unable to flow smoothly out of the vehicle through the airflow channel 110.

[0049] In one embodiment, the valve body frame 220 includes a recessed platform 260, which surrounds the air inlet 111. The valve body assembly 200 is fixed to the recessed platform 260. Specifically, to better connect the valve body assembly 200 frame to the airflow channel 110, a recessed platform 260 is provided and fixed between the valve body frame 220 and the air inlet 111. The cross-sectional shape of the recessed platform 260 can be adapted according to the connection requirements between the valve body frame 220 and the air inlet 111, including but not limited to circular, rectangular, polygonal, or other irregular shapes. The recessed platform 260 has an opening in the middle of the plate away from the edge of the plate to form the air inlet 111. The air inlet 111 is located at the geometric center of the recessed platform 260, at the connection point with the body of the recessed platform 260. Chamfering, rounding, or smooth transition treatments can be performed to optimize the stress distribution of the valve body assembly 200 connected to the recessed platform 260 and facilitate subsequent assembly. Meanwhile, auxiliary structures such as reinforcing edges, mounting bosses, or sealing grooves can be set at the edge of the sunken platform 260.

[0050] Furthermore, the valve body frame 220 also includes an outer edge frame 270, which protrudes from the recessed platform 260 and is arranged around the recessed platform 260. Sound-absorbing cotton is provided on the side of the outer edge frame 270 away from the recessed platform 260.

[0051] Specifically, an outer edge frame 270 is provided on the valve body assembly 200. The outer edge frame 270 is used to fix the valve body frame 220 to the recessed platform 260. The specific shape of the outer edge frame 270 can be selected according to the actual connection method between the valve body frame 220 and the recessed platform 260 to ensure a seal between the valve body assembly 200 and the air inlet 111. At the same time, sound-absorbing cotton is provided on the outer edge frame 270. The sound-absorbing cotton on the outer edge frame 270 can further ensure that the valve body assembly 200 remains sealed at the connection point to the air outlet 310 and to reduce noise generated by gaps at the connection point.

[0052] In one embodiment, the body assembly 10 includes an air vent grille 300 located on the side of the bumper housing 100 facing the outside of the vehicle. The air vent grille 300 is connected to the bumper housing 100. The air vent grille 300 includes a plurality of guide strips 311, each guide strip 311 spanning an air vent 310. The plurality of guide strips 311 are arranged sequentially, with a gap between adjacent guide strips 311.

[0053] An air vent grille 300 is provided at the rear of the vehicle. The air vent grille 300 is inclined towards the outside of the bumper housing 100 and consists of multiple horizontal guide strips 311 extending along the left-right direction of the vehicle and arranged at regular or irregular intervals along the vertical direction of the vehicle to form air vents 310. Preferably, the air vent grille 300 is composed of a series of guide strips 311 with specific inclination angles. The angles of the guide strips 311 can be fixed or actively adjustable, depending on the specific requirements. The end of the air vent grille 300 away from the bumper housing 100 is inclined towards the outside of the vehicle to form the air vent 310, which connects the airflow channel 110 and the outside of the vehicle. When the vehicle is in motion, the airflow and noise generated enter the airflow channel 110 through the air inlet 111 on the valve body assembly 200 inside the vehicle and are then discharged through the air vent 310 on the grille. The 300 air vent grille is designed to slope downwards towards the vehicle, ensuring airflow while preventing water from entering the vehicle interior during rain or car washes. Furthermore, the 300 air vent grille design is integrated with the rear styling of the vehicle, taking into account aesthetic attributes and enhancing the overall quality of the product.

[0054] In summary, the airflow channel 110 connects the inside and outside of the vehicle. When the air pressure inside the vehicle is greater than the air pressure outside the vehicle during driving, the deflector 210 on the air intake 111 will open, allowing the airflow inside the vehicle to enter the airflow channel 110 through the air intake 111. Then, the airflow is discharged to the outside of the vehicle through the air outlet 310 of the air outlet grille 300. At the same time, the airflow channel 110 can also isolate the noise generated by the wheels and electric drive from reaching the inside of the vehicle.
