Description

Technical Field

[0001] This application relates to the field of vehicle design technology, specifically to a vehicle body structure and a vehicle. Background Technology

[0002] As a core component of a vehicle's passive safety system, airbags can deploy rapidly in the event of a collision to protect the safety of occupants. The airbag control unit (ACU), as the control core of the airbag system, can collect, analyze, judge, and process signals captured by collision sensors. Once a collision is determined, the airbag control unit will immediately issue a command to activate the gas generator to deploy the airbag.

[0003] In the existing technology, airbag controllers are usually fixed under the front seats. The signal transmission of airbag controllers lacks shielding design, which makes the signal transmission susceptible to interference and has high error, seriously affecting the accuracy of airbag controllers in judging collision intensity. In addition, this installation position cannot meet the needs of different vehicle models, resulting in poor versatility. Utility Model Content

[0005] To address the aforementioned issues, this application discloses a vehicle body structure having intersecting first, second, and third directions. The vehicle body structure includes a floor, a bracket, an airbag controller, an airbag body, a steering wheel, and a sub-instrument panel. The airbag body is installed within the steering wheel, and the airbag controller is electrically connected to the airbag body. A mounting position is provided on the floor, and along the first direction, the position of the mounting position corresponds to the position of the sub-instrument panel. The bracket is installed at the mounting position, and the airbag controller is installed on the bracket.

[0006] Optionally, the bracket is provided with a first connecting structure, and the mounting position is provided with a second connecting structure. The first connecting structure and the second connecting structure are detachably connected to install the bracket at the mounting position.

[0007] Optionally, a portion of the floor protrudes along the first direction to form a protrusion, the protrusion including a top wall and a side wall surrounding the top wall, wherein the top wall is perpendicular to the first direction, and the mounting position is formed on the top wall and the side wall; the bracket includes a first connecting portion and a second connecting portion connected to each other, the first connecting portion being connected to the top wall, and the second connecting portion being connected to the side wall.

[0008] Optionally, the sidewall includes a first wall surface and a second wall surface disposed opposite to each other along the second direction; the second connecting portion is connected to the first wall surface, or the second connecting portion is connected to the second wall surface.

[0009] Optionally, the bracket further includes a support portion, which is connected to the first connecting portion and the second connecting portion respectively. The support portion includes a first portion and a second portion that are connected to each other. The first portion extends along the second direction, and one side of the first portion along the second direction is connected to the first connecting portion, while the other side protrudes from the second connecting portion. The second portion extends along the first direction and is connected to the second connecting portion. The first portion and the second portion enclose a support space. The side of the first portion facing away from the support space has a support surface, and the airbag controller is mounted on the support surface.

[0010] Optionally, the number of the support portions is at least two, and the at least two support portions are spaced apart along the third direction; the support surfaces of each support portion are located on the same plane.

[0011] Optionally, a third connecting structure is provided on the support surface, and a fourth connecting structure is provided on the airbag controller. The third connecting structure and the fourth connecting structure are detachably connected to install the airbag controller on the support surface.

[0012] Optionally, the top wall and the side wall are connected by an arc-shaped transition, and the connection between the top wall and the side wall forms a first arc; the first connecting part and the second connecting part are connected by an arc-shaped transition, and the connection between the first connecting part and the second connecting part forms a second arc; the first arc and the second arc are the same.

[0013] Optionally, the bracket is a sheet metal part.

[0014] This application also discloses a vehicle including the body structure described in any of the foregoing claims.

[0015] The vehicle body structure disclosed in this application has at least the following advantages: In the vehicle body structure of this application, the airbag controller is mounted on a floor mounting position via a bracket. That is, the airbag controller is installed below the sub-dashboard, creating a physical separation between the airbag controller and the electrical components on the surface of the sub-dashboard. This helps prevent electromagnetic signals generated by the electrical components during operation from directly radiating to the airbag controller. Simultaneously, the sub-dashboard also acts as an electromagnetic shielding barrier, further reducing external electromagnetic interference. This effectively solves the problem of interference affecting the airbag controller's signal transmission, reduces signal transmission errors, and improves the accuracy of the airbag controller's collision intensity assessment. This, in turn, helps ensure the timely deployment of the airbag, protecting the safety of the vehicle occupants. Furthermore, by mounting the airbag controller on the floor below the sub-dashboard, the airbag controller can route its wiring through the cavity formed between the sub-dashboard and the floor, connecting to components such as collision sensors and gas generators. This shortens the wiring path, reduces the exposed length of the wiring harness, lowers the risk of wiring tangling, and thus reduces the probability of wiring harness interference, further improving the efficiency and accuracy of signal transmission.

[0016] Furthermore, the airbag controller is mounted on the floor below the passenger dashboard, ensuring it does not come into contact with electrical components on the dashboard or be touched by occupants, effectively preventing accidental deployment due to contact or impact. The airbag controller is also fixed to the floor via a bracket, eliminating the need for additional design or mold modifications, thus helping to control development costs.

[0017] On the other hand, the sub-dashboard area is a common area for both left-hand drive and right-hand drive models. Installing the airbag controller here, compared to the existing technology of fixing it under the front seat, eliminates the need to develop separate mounting brackets and wiring schemes for left-hand drive and right-hand drive models. Only one bracket and corresponding wiring scheme need to be designed to adapt to the production needs of both models, thereby improving the universality of the vehicle body structure.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides a vehicle body structure, referring to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the vehicle body structure in an embodiment of this application. Figure 2 This is a partial schematic diagram of the vehicle body structure in an embodiment of this application.

[0023] The vehicle body structure provided in this application embodiment has a first direction Z, a second direction X and a third direction Y that intersect each other in pairs. The vehicle body structure includes a floor 1, a bracket 2, an airbag controller 3, an airbag body, a steering wheel 4 and a sub-instrument panel. The airbag body is installed in the steering wheel 4 and the airbag controller 3 is electrically connected to the airbag body. An installation position is provided on the floor 1, and the position of the installation position corresponds to the position of the sub-instrument panel along the first direction Z. The bracket 2 is installed in the installation position and the airbag controller 3 is installed on the bracket 2.

[0024] Specifically, the vehicle body structure described in this application can be applied to both left-hand drive and right-hand drive vehicles. Figure 1 The diagram shows a schematic of the body structure of a right-hand drive vehicle, such as... Figure 1 As shown, the vehicle body structure has a first direction Z, a second direction X, and a third direction Y that intersect each other. The first direction Z can be regarded as the height direction of the vehicle body structure, the second direction X can be regarded as the length direction of the vehicle body structure, and the third direction Y can be regarded as the width direction of the vehicle body structure.

[0025] The vehicle body structure includes an airbag assembly, which consists of an airbag body, a spiral cable, a gas generator, and an airbag controller 3. The airbag body, when folded, is embedded inside the cover of the steering wheel 4, located in the center area of ​​the steering wheel 4. The gas generator is integrated with the airbag body and fixed to the frame of the steering wheel 4. The airbag controller 3 is electrically connected to the gas generator via a spiral cable and a dedicated shielded wiring harness, forming a control circuit for signal transmission. The vehicle body structure also includes collision sensors, which are typically distributed on the front beams of the vehicle body and electrically connected to the airbag controller 3.

[0026] When a vehicle collision occurs, the airbag controller 3 can quickly collect signals from the collision sensor. At the same time, the accelerometer built into the airbag controller 3 can quickly collect the deceleration signal of the vehicle body. If the collected signal meets the preset trigger threshold, the airbag controller 3 can immediately output a trigger command. The trigger command is transmitted to the igniter built into the gas generator through a spiral cable and a dedicated shielded wire harness. The igniter is powered on and heats up, instantly igniting the internal agent and producing a large amount of nitrogen gas. This causes the internal pressure of the gas generator to rise sharply, quickly inflating the folded airbag body, thereby causing the airbag body to quickly deploy and form a cushioning airbag.

[0027] Floor 1, serving as the load-bearing foundation at the bottom of the vehicle body, is typically made of high-strength steel or alloy sheet through stamping, possessing good strength and rigidity to meet the collision and torsional resistance requirements of the vehicle body structure. Floor 1 has mounting positions, which can be a portion of the floor 1. For example, the mounting position can be located in the central area of ​​floor 1, along the first direction Z, corresponding to the position of the sub-instrument panel. That is, this area is located directly below the sub-instrument panel. The sub-instrument panel, also known as the central tunnel, is a raised structure in the vehicle body structure located between the driver's seat and the front passenger seat, extending longitudinally (i.e., in the vehicle's longitudinal direction), serving multiple functions including structural support, functional integration, and space utilization.

[0028] The mounting position corresponds to the position of the sub-dashboard, meaning that a closed or semi-closed cavity structure can be formed above the mounting position. This cavity structure belongs to the space below the sub-dashboard, and can accommodate wiring harnesses for connecting electrical components in the vehicle. Outside the cavity, i.e., on the upper surface of the sub-dashboard, a bearing surface can be formed for mounting electrical components such as the gear shift mechanism, multimedia control buttons, and charging panel. It should be noted that in the embodiments of this application, "above" refers to the direction closer to the top of the vehicle body along the height direction of the vehicle body structure, and "below" refers to the direction closer to the bottom of the vehicle body along the height direction of the vehicle body structure.

[0029] like Figure 2As shown, bracket 2 is installed at the mounting position, and airbag controller 3 is installed on bracket 2. That is, airbag controller 3 is installed below the sub-dashboard. This arrangement can, on the one hand, create a physical separation between airbag controller 3 and electrical components on the surface of the sub-dashboard, which helps to prevent electromagnetic signals generated by electrical components during operation from directly radiating to airbag controller 3. At the same time, the sub-dashboard can also act as an electromagnetic shielding barrier, further weakening external electromagnetic interference. This can effectively solve the problem of signal transmission of airbag controller 3 being susceptible to interference, reduce signal transmission errors, improve the accuracy of airbag controller 3 in judging collision intensity, and thus help ensure that the airbag can deploy in time and protect the safety of the occupants.

[0030] In addition, the airbag controller 3 is installed on the floor 1 below the sub-instrument panel. The airbag controller 3 can be routed through the cavity formed between the sub-instrument panel and the floor to connect with components such as collision sensors and gas generators. This facilitates the routing path, reduces the length of exposed wiring harnesses, reduces the risk of wiring harnesses crossing and tangling, thereby reducing the probability of wiring harnesses being interfered with, and further improving the efficiency and accuracy of signal transmission.

[0031] Furthermore, the airbag controller 3 is installed on the floor 1 below the passenger dashboard, ensuring it does not come into contact with electrical components on the passenger dashboard or be touched by passengers, effectively preventing accidental deployment due to contact or impact. Moreover, the airbag controller 3 is fixed to the floor 1 via a bracket 2, eliminating the need for additional design or mold modifications, thus helping to control development costs.

[0032] On the other hand, the sub-dashboard area is a common area for both left-hand drive and right-hand drive models. The airbag controller 3 is installed here. Compared with the existing technology of fixing it under the front seat, this application does not need to develop separate mounting brackets and wiring schemes for left-hand drive and right-hand drive models. Only one bracket 2 and corresponding wiring scheme need to be designed to adapt to the production needs of the two models, thereby improving the universality of the vehicle body structure.

[0033] In addition, the secondary instrument panel is located near the center of the vehicle, and the airbag controller 3 is installed on the floor 1 below the secondary instrument panel. Corresponding to the position of the secondary instrument panel, the airbag controller 3 can more accurately sense the deceleration changes of the whole vehicle. Moreover, the distance from the left and right sides of the vehicle is almost the same. No matter whether the vehicle is involved in a collision on the left or right side, the airbag controller 3 can receive the signals from the collision sensor more evenly, effectively improving the problem of delay or decrease in accuracy of single-sided collision signal acquisition.

[0034] In addition, the space below the sub-dashboard is relatively independent in both left-hand drive and right-hand drive models and is not affected by the dynamic adjustment of the seat. The airbag controller 3 is installed here, which helps to reduce the wiring difficulty of the airbag controller 3 and at the same time ensures the reliability of the electrical connection of the airbag controller 3.

[0035] Refer to together Figure 3 , Figure 3 This is a schematic diagram of the bracket in an embodiment of this application.

[0036] Optionally, in some embodiments of this application, the bracket 2 is provided with a first connecting structure 201 and the mounting position is provided with a second connecting structure. The first connecting structure 201 and the second connecting structure are detachably connected to install the bracket 2 in the mounting position.

[0037] Specifically, one of the first connecting structure 201 and the second connecting structure can be a buckle, and the other can be a slot. The buckle is engaged in the slot to achieve a detachable connection between the bracket 2 and the mounting position. Alternatively, both the first connecting structure 201 and the second connecting structure can be connecting holes, through which fasteners such as bolts, screws, and rivets are inserted to achieve a detachable connection between the bracket 2 and the mounting position. In this embodiment, the first connecting structure 201 and the second connecting structure achieve a detachable connection between the bracket 2 and the mounting position on the floor 1, which facilitates the disassembly and maintenance of the assembly formed by the bracket 2 and the airbag controller 3, saving maintenance costs.

[0038] Optionally, in some embodiments of this application, such as Figure 2 As shown, a portion of the floor 1 protrudes along the first direction Z to form a protrusion 11. The protrusion 11 includes a top wall 111 and a side wall 112 surrounding the top wall 111. The top wall 111 is perpendicular to the first direction Z. A mounting position is formed on the top wall 111 and the side wall 112. The bracket 2 includes a first connecting portion 21 and a second connecting portion 22 that are connected to each other. The first connecting portion 21 is connected to the top wall 111, and the second connecting portion 22 is connected to the side wall 112.

[0039] Specifically, a portion of the floor 1 protrudes upward along the height direction of the vehicle body structure to form a protrusion 11, the position of which corresponds to the position of the sub-instrument panel. The structural design of the protrusion 11 helps to strengthen the local strength of the floor 1, reduce the risk of local deformation, and provide stable support for the airbag controller 3 and the components in the cavity below the sub-instrument panel.

[0040] The protrusion 11 includes a top wall 111 and side walls 112. The top wall 111 is perpendicular to the first direction Z. In this embodiment, "perpendicular" includes not only absolute perpendicularity but also near-perpendicularity as commonly understood. The side walls 112 surround the periphery of the top wall 111. The protrusion 11 on the floor 1 is typically close to a cuboid structure, thus the side walls 112 include four surfaces. The side walls 112 extend along the first direction Z, forming a certain angle with the first direction Z. The angle can range from 0° to 30°, meaning the side walls 112 extend inclinedly to the first direction Z. This allows for the formation of... Figure 2 The structure shown.

[0041] The bracket 2 includes a first connecting part 21 and a second connecting part 22 that are connected to each other. The first connecting part 21 is connected to the top wall 111, and the second connecting part 22 is connected to the side wall 112. Thus, the bracket 2 and the protrusion 11 establish a connection relationship between two planes, which helps to improve the connection reliability between the bracket 2 and the protrusion 11, thereby improving the installation stability of the airbag controller 3.

[0042] Optionally, in some embodiments of this application, the sidewall 112 includes a first wall surface and a second wall surface disposed opposite to each other along the second direction X; the second connecting portion 22 is connected to the first wall surface, or the second connecting portion 22 is connected to the second wall surface.

[0043] Specifically, since the second direction X is the length direction of the vehicle body structure, the first wall and the second wall can be regarded as the front wall near the front of the vehicle and the rear wall near the rear of the vehicle of the protrusion 11. The second connecting part 22 of the bracket 2 is connected to the first wall or the second wall, which is equivalent to the second connecting part 22 of the bracket 2 being connected to the front wall or the rear wall of the protrusion 11.

[0044] Since the left and right walls of the protrusion 11 are close to the front seats, and the surrounding area is usually equipped with components such as seat rails and seat adjustment motors, if the second connecting part 22 is connected to the left and right walls, it means that the airbag controller 3 is installed close to the seat and is prone to interference with the surrounding components of the seat. Therefore, in this embodiment, the second connecting part 22 is connected to the front or rear wall of the protrusion 11, so that the airbag controller 3 is closer to the center of the vehicle body and farther away from the surrounding components of the seat, which makes it easier to install and arrange the airbag controller 3.

[0045] In addition, the objects connected to the airbag controller 3, such as the collision sensor and the spiral cable of the airbag assembly, are mostly located near the center of the vehicle body. Installing the airbag controller 3 near the front and rear walls of the protrusion 11 allows the wiring harness to extend along the front and rear direction of the protrusion 11 without having to go around laterally, further shortening the wiring path and reducing the risk of the wiring harness crossing and tangling.

[0046] In addition, during vehicle operation, the main force generated is lateral force. Connecting the second connecting part 22 of the bracket 2 to the front or rear wall of the protrusion 11 helps to disperse the force on the bracket 2, reduce the risk of deformation of the bracket 2 under shear force, thereby improving the connection reliability between the bracket 2 and the protrusion 11 and ensuring the installation stability of the airbag controller 3.

[0047] Optionally, in some embodiments of this application, such as Figure 3As shown, the top wall 111 and the side wall 112 are smoothly connected, and the connection between the top wall 111 and the side wall 112 forms a first arc; the first connecting part 21 and the second connecting part 22 are connected in an arc shape, and the connection between the first connecting part 21 and the second connecting part 22 forms a second arc; the first arc and the second arc are the same.

[0048] Specifically, the connection between the top wall 111 and the side wall 112 forms a first arc, which reduces stress concentration and improves the structural stability of the protrusion 11. The protrusion 11 can be a one-piece molded structure, ensuring good strength and rigidity while saving processes and controlling costs. The connection between the first connecting part 21 and the second connecting part 22 forms a second arc, and the first arc is the same as the second arc. This arrangement allows the connection between the first connecting part 21 and the second connecting part 22 to fully fit with the connection between the top wall 111 and the side wall 112, and also ensures a full fit between the first connecting part 21 and the top wall 111, and between the second connecting part 22 and the side wall 112, thereby improving the connection reliability between the bracket 2 and the protrusion 11. Simultaneously, the arc-shaped transition connection can improve the stress concentration phenomenon of the bracket 2, reducing the possibility of the bracket 2 breaking at the connection between the first connecting part 21 and the second connecting part 22, and improving the structural stability of the bracket 2.

[0049] Optionally, in some embodiments of this application, such as Figure 3 As shown, the bracket 2 also includes a support portion 23, which is connected to the first connecting portion 21 and the second connecting portion 22 respectively. The support portion 23 includes a first part 231 and a second part 232 that are connected to each other. The first part 231 extends along the second direction X, and one side of the first part 231 along the second direction X is connected to the first connecting portion 21, while the other side protrudes from the second connecting portion 22. The second part 232 extends along the first direction Z and is connected to the second connecting portion 22. The first part 231 and the second part 232 enclose a support space 233. The side of the first part 231 facing away from the support space 233 has a support surface 230, and the airbag controller 3 is installed on the support surface 230.

[0050] Specifically, the first part 231 extends along the second direction X, forming a flat plate structure. One side of the first part 231 along the second direction X connects to the first connecting part 21, and the other side of the first part 231 along the second direction X protrudes from the second connecting part 22 to provide space for the second part 232. The second part 232 connects to the side of the first part 231 near the second connecting part 22. The second part 232 extends along the first direction Z, and one side of the second part 232 along the second direction X connects to the second connecting part 22. The extension direction of the second part 232 may be slightly inclined to the first direction Z. Simultaneously, the second part 232 may have a bent structure to enhance its structural strength. The first part 231 and the second part 232 enclose a supporting space 233, such as... Figure 3 As shown, the support space 233 is similar to a trapezoidal cavity, which helps to improve the structural stability of the support 2.

[0051] The first part 231 has a support surface 230 on the side opposite to the support space 233. The airbag controller 3 is mounted on the support surface 230. Since the first part 231 extends along the second direction X, it can form a support surface 230 perpendicular to the first direction Z. Thus, it is equivalent to mounting the airbag controller 3 on the horizontal support surface 230. Since the airbag controller 3 has a built-in acceleration sensor, the detection accuracy of the acceleration sensor is directly related to the installation posture. Horizontal mounting of the airbag controller 3 helps ensure the accuracy of its internal acceleration sensor detection, thereby helping to ensure the accuracy of the airbag controller 3 in judging the collision intensity and avoiding false triggering or delayed response of the airbag due to posture errors. In addition, the horizontal support surface 230 can provide a flatter positioning reference for the airbag controller 3. There is no need to adjust the tilt angle when installing the airbag controller 3, which helps to simplify the installation method and achieve rapid installation.

[0052] In some embodiments, a flexible pad can be attached to the support surface 230. The flexible pad can be made of materials such as rubber or silicone. The surface of the flexible pad has anti-slip texture. This can buffer the high-frequency vibrations brought about by the vehicle driving, reduce fatigue damage to the internal components of the airbag controller 3, and also reduce the friction on the surface of the airbag controller 3, thus solving the problem of abnormal noise caused by the direct contact between the airbag controller 3 and the bracket 2.

[0053] Optionally, in some embodiments of this application, the flatness of the support surface 230 does not exceed 0.3 mm. The flatness of the support surface 230 within this range effectively ensures the horizontal installation of the airbag controller 3, ensuring the accuracy of the detection by its built-in acceleration sensor, thereby guaranteeing the accuracy of the airbag controller 3 in judging the collision intensity. Furthermore, the flatness of the support surface 230 within this range helps ensure that the surface of the airbag controller 3 fully conforms to the support surface 230, thereby evenly distributing the weight and vibration load of the controller across the entire support surface 230, significantly reducing stress concentration and improving the installation stability of the airbag controller 3.

[0054] Alternatively, the inclination of the support surface 230 relative to the horizontal plane shall not exceed 3°. Similarly, by adopting the above-mentioned setting for the support surface 230, the detection axis deviation of the accelerometer built into the airbag controller 3 due to excessive tilting of the installation posture can be avoided, thereby ensuring the accuracy of the accelerometer detection and guaranteeing the accuracy of the airbag controller 3 in judging the collision intensity. In addition, if the inclination of the support surface 230 relative to the horizontal plane is too large, it is easy for the airbag controller 3 to generate continuous torsional stress due to its own weight, causing problems such as loosening of the connection. Therefore, setting the inclination of the support surface 230 relative to the horizontal plane within the above-mentioned range also helps to ensure the installation stability of the airbag controller 3.

[0055] Of course, the support surface 230 can also simultaneously meet the following requirements: the flatness of the support surface 230 does not exceed 0.3mm, and the inclination of the support surface 230 relative to the horizontal plane does not exceed 3°, in order to achieve better results.

[0056] Optionally, in some embodiments of this application, such as Figure 3 As shown, the number of support parts 23 is at least two, and at least two support parts 23 are arranged at intervals along the third direction Y; the support surface 230 of each support part 23 is located on the same plane.

[0057] Specifically, there are two or more support parts 23, and the support surfaces 230 of each support part 23 are located on the same plane. The airbag controller 3 is installed on this plane. This arrangement can provide stable support for the airbag controller 3 and avoid the individual support parts 23 from being too large and increasing the weight of the bracket 2. Figure 2 The diagram shows a case where there are two support parts 23. The two support parts 23 are spaced apart along the third direction Y, that is, the width direction of the vehicle body structure. The two support parts 23 can be well adapted to the specifications of the airbag controller 3 commonly used in actual applications.

[0058] Refer to together Figure 4 , Figure 4 This is a schematic diagram of the airbag controller in an embodiment of this application.

[0059] Optionally, in some embodiments of this application, such as Figure 3 As shown, a third connecting structure 202 is provided on the support surface 230, such as... Figure 4 As shown, the airbag controller 3 is provided with a fourth connection structure 301. The third connection structure 202 and the fourth connection structure 301 are detachably connected to each other so as to install the airbag controller 3 on the support surface 230.

[0060] Specifically, one of the third connecting structure 202 and the fourth connecting structure 301 can be a buckle, and the other can be a slot. The buckle is engaged in the slot to fix the airbag controller 3 to the support surface 230. Alternatively, both the third connecting structure 202 and the fourth connecting structure 301 can be connecting holes, through which fasteners such as bolts, screws, and rivets are inserted to fix the airbag controller 3 to the support surface 230. In this embodiment, the third connecting structure 202 and the fourth connecting structure 301 achieve a detachable connection between the airbag controller 3 and the support surface 230, which facilitates the disassembly and maintenance of the airbag controller 3 in the future and saves maintenance costs.

[0061] Optionally, in some embodiments of this application, the bracket 2 is a sheet metal part. For example, a bracket 2 with a structure including a first connecting part 21, a second connecting part 22, and a supporting part 23 can be formed by stamping high-strength steel plates. Its weight is low, which is beneficial for controlling the weight of the vehicle body structure. At the same time, sheet metal processing has high production efficiency and low mold costs, further facilitating cost control. In addition, the metal sheet metal bracket 2 can serve as an electromagnetic shielding medium, forming a conductive path with the airbag controller 3. This conducts the static electricity and electromagnetic interference from the airbag controller 3 to the floor 1 through the bracket 2, further reducing electromagnetic interference to the signal transmission of the airbag controller 3 and ensuring signal processing accuracy.

[0062] This application also provides a vehicle, which may include pure electric vehicles, hybrid vehicles, range-extended vehicles, and gasoline vehicles, etc. This application does not limit the power source of the vehicle. The vehicle may also include small cars, medium-sized cars, trucks, vans, trailers, CDVs (Car Derived Vans), MPVs (Multi-Purpose Vehicles), SUVs (Sport Utility Vehicles), etc. This application does not limit the type of vehicle.

[0063] The vehicle includes the body structure of any of the foregoing embodiments. In the body structure of this application embodiment, the airbag controller is mounted on a floor mounting position via a bracket, that is, the airbag controller is mounted below the sub-dashboard, thus creating a physical separation between the airbag controller and the electrical components on the surface of the sub-dashboard. This helps to prevent electromagnetic signals generated when the electrical components are working from directly radiating to the airbag controller. At the same time, the sub-dashboard can also act as an electromagnetic shielding barrier, further weakening external electromagnetic interference. In this way, the problem of the airbag controller's signal transmission being susceptible to interference can be effectively solved, signal transmission errors can be reduced, and the accuracy of the airbag controller in judging the collision intensity can be improved. This, in turn, helps to ensure that the airbag can deploy in a timely manner and protect the safety of the occupants. In addition, the sub-dashboard area is a common area for both left-hand drive and right-hand drive models. By mounting the airbag controller here, it is not necessary to develop separate mounting brackets and wiring schemes under the seats for left-hand drive and right-hand drive models. Only one bracket and corresponding wiring scheme need to be designed to adapt to the production needs of both models, thereby improving the versatility of the body structure. It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
