Description

Technical Field

[0001] This utility model relates to the field of vehicle body technology, and in particular to a body structure. It also relates to a vehicle equipped with this body structure. Background Technology

[0002] The current vehicle has a ring-shaped structure consisting of the side panels on both sides of the body, the roof assembly at the top of the side panels, and the floor assembly at the bottom of the side panels.

[0003] When a vehicle rolls over under the pressure of the roof, the insufficient strength and rigidity of the body structure result in poor overall stability of the vehicle. The compressive force is directly borne by the roof assembly and the single-sided side assembly, making the sheet metal prone to bending and damaging the body structure. Furthermore, the passenger compartment is easily crushed, thus causing vehicle damage and endangering the personal safety of the occupants. Utility Model Content

[0004] In view of this, the present invention aims to propose a vehicle body structure to enhance the overall strength and safety of the vehicle body.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A vehicle body structure has a ring structure in its middle, the ring structure being formed by B-pillars placed on both sides of the vehicle body, a roof assembly connected to the top of the B-pillars on both sides, a sill beam assembly connected to the bottom of the B-pillars on both sides, and a seat beam connecting the sill beam assemblies on both sides.

[0007] The annular structure is provided with a reinforcing structure located in the vehicle interior space. The reinforcing structure connects at least two connection points of the annular structure, and the two connection points are distributed at intervals along the circumference of the annular structure.

[0008] Furthermore, the reinforcing structure includes a first reinforcing structure and a second reinforcing structure, which are symmetrically arranged within the space surrounded by the annular structure, and the two ends of the first reinforcing structure and the second reinforcing structure are respectively connected to the annular structure.

[0009] Furthermore, the two connection points where the first reinforcing structure connects to the annular structure are the connection points between the B-pillars on both sides and the top cover assembly;

[0010] The two connection points where the second reinforcing structure connects to the ring structure are the connection points between the B-pillars and the seat crossbeams on both sides.

[0011] Furthermore, both the first reinforcing structure and the second reinforcing structure include a connecting beam and connecting plates disposed at both ends of the connecting beam, the connecting plates being connected to the annular structure.

[0012] Furthermore, each of the connection positions of the annular structure is provided with a mounting plate, and the connecting plate and the mounting plate are detachably connected by a first connecting member.

[0013] Furthermore, all of the connecting beams are arc-shaped.

[0014] Furthermore, the middle portions of the two connecting beams abut against each other in the vertical direction of the vehicle.

[0015] Furthermore, the two connecting beams are detachably connected at their midpoints via a second connector.

[0016] Furthermore, the connecting beam has a cavity that extends along the bending direction of the connecting beam.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The vehicle body structure described in this utility model comprises a ring-shaped structure consisting of several key components, including B-pillars, a roof assembly, and seat crossbeams. The two B-pillars are located on either side of the vehicle body, providing stable support. The roof assembly connects to the top of these two B-pillars, forming the upper part of a closed ring structure. The seat crossbeams connect to the bottom of the two B-pillars, closing the lower part of the ring structure and enhancing its strength and stability. A reinforcing structure is installed inside the ring structure, connecting at least two points on the ring structure at intervals along its circumference. This design ensures that the reinforcing structure effectively disperses and resists forces from all directions, significantly enhancing the overall strength and safety of the vehicle body and providing passengers with a safer and more comfortable riding environment.

[0019] Furthermore, a first and a second reinforcing structure are incorporated, symmetrically arranged within the space enclosed by the ring structure. This design is not only aesthetically pleasing but also distributes forces more evenly, enhancing the stability and strength of the entire ring structure. The two ends of the first and second reinforcing structures are connected to the ring structure, ensuring that the reinforcing structures effectively transmit forces to all parts of the ring structure, thereby strengthening the rigidity and impact resistance of the entire vehicle body structure.

[0020] In addition, the two connection points between the first reinforcing structure and the ring structure are the connection points between the B-pillars on both sides and the roof assembly, while the two connection points between the second reinforcing structure and the ring structure are the connection points between the B-pillars on both sides and the seat crossbeams. This connection method can not only better strengthen the overall strength of the ring structure, but also help improve the torsional stiffness of the entire vehicle body structure, thereby improving the overall stability and durability of the vehicle body structure, and further enhancing the vehicle's safety and ride comfort.

[0021] In this structure, the upper and lower joints of the B-pillar serve as connection points, connecting the side assemblies and sill beam assemblies on the left and right sides. When the vehicle is subjected to roof pressure and rolls over, the compressive force from the roof will be effectively distributed to the left and right side assemblies, sill beams, seat crossbeams, and reinforcing structures, which can effectively prevent damage to the vehicle body structure.

[0022] The first and second reinforcing structures employ similar construction methods, both including connecting beams and connecting plates. The connecting beams are the main load-bearing components of the reinforcing structures, responsible for transmitting and distributing forces, thereby enhancing the strength and stability of the ring structure.

[0023] The connecting plates are located at both ends of the connecting beam. Their main function is to connect the reinforcing structure and the ring structure, ensuring a tight fit. This tight connection helps to effectively transfer the force of the reinforcing structure to the ring structure, thereby improving the overall performance of the entire vehicle body structure. The combination of the connecting beam and connecting plates allows the first and second reinforcing structures to form a robust and stable whole, effectively enhancing the strength and durability of the ring structure.

[0024] The mounting plate located where the first and second reinforcing structures connect to the ring structure provides a more robust and reliable connection interface, enabling the reinforcing structures to connect more effectively to the ring structure. The connection between the connecting plate and the mounting plate is detachable, making the installation and removal of the reinforcing structure more convenient, which is beneficial for vehicle maintenance and repair. Furthermore, the detachable connection method provides greater flexibility, allowing for adjustments and optimizations to the position and layout of the reinforcing structure during the vehicle design phase.

[0025] The connecting beams are designed in an arc shape. This arc shape allows the connecting beams to better distribute and resist forces from all directions, thereby improving the strength and stability of the entire vehicle body structure. The robust and stable body structure can better absorb and disperse road vibrations and noise, thus enhancing driving and passenger comfort. In addition, the arc-shaped connecting beams not only have a practical function but also add a streamlined and dynamic aesthetic to the vehicle body.

[0026] Furthermore, the two connecting beams are designed to abut against each other at their midpoints, forming a more stable and continuous reinforced structure. This continuity helps to better distribute and resist forces from all directions, more effectively improving the strength and stability of the ring structure, thereby enhancing the overall performance of the vehicle body structure. When the two connecting beams abut against each other at their midpoints, they can jointly resist torsional forces from the vehicle body, thus increasing the vehicle's torsional stiffness, which helps to improve the vehicle's handling and stability.

[0027] Meanwhile, the two connecting beams are detachably connected at the middle via a second connector, allowing them to be easily separated and reconnected when needed. This greatly simplifies maintenance and replacement processes, reduces repair costs, and improves maintenance efficiency. The detachable connection via the connector allows the beams to withstand greater forces and torques, ensuring a stable and reliable reinforced structure when connected, thus contributing to improved overall strength and durability of the vehicle body structure.

[0028] By incorporating cavities within the connecting beam, the amount of material used can be significantly reduced, thus achieving weight reduction. This is of great significance for improving vehicle fuel economy, reducing emissions, and decreasing energy consumption. Furthermore, this structure is not only lightweight but also ensures that the connecting beam maintains sufficient strength under various forces and torques. The presence of the cavities also increases the bending and torsional stiffness of the connecting beam, thereby enhancing the reinforcing effect of the strengthening structure on the ring structure and ultimately improving the overall performance of the vehicle body structure.

[0029] Another objective of this utility model is to provide a vehicle having the body structure described above.

[0030] By applying the aforementioned body structure, the vehicle described in this utility model can improve its torsional stiffness and impact resistance. When the vehicle is subjected to top pressure or rollover, the ring structure and reinforcing structure in the body structure work together to improve the vehicle's handling and stability, better protect the occupants, and enhance the vehicle's safety.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] This embodiment relates to a vehicle body structure that addresses the problem of insufficient strength in the B-ring. By improving its structure, the traditional force transmission path can be altered. When applied to a vehicle body, this structure can enhance the overall strength and safety of the vehicle body, providing passengers with a safer and more comfortable riding environment.

[0045] Based on the above design concept, an exemplary structure of the vehicle body structure in this embodiment is as follows: Figure 1 As shown, in terms of overall structure, the vehicle body structure mainly includes a ring structure and a reinforcing structure located inside the ring structure within the vehicle interior space.

[0046] In the longitudinal direction of the vehicle beam, the ring structure is located in the middle of the vehicle body. In this embodiment, the ring structure is formed by B-pillars 3 located on both sides of the vehicle body, a roof assembly 5 connecting the top of the B-pillars 3 on both sides, sill beam assemblies 9 connecting the bottom of the B-pillars 3 on both sides, and a seat crossbeam 4 connecting the sill beam assemblies 9 on both sides. This ring structure is the commonly referred to B-ring. The reinforcing structure is located inside the ring structure and connects at least two connection points of the ring structure, and the two connection points are distributed at intervals along the circumference of the ring structure.

[0047] In this embodiment, the vehicle body structure has two B-pillars 3 located on both sides of the vehicle body, which can provide stable support for the vehicle body. The roof assembly 5 is connected to the top of the two B-pillars 3, which can form the upper part of a closed ring structure. The seat beam 4 is connected to the bottom of the two B-pillars 3, which can close the lower part of the ring structure. This structural arrangement can enhance the strength and stability of the ring structure.

[0048] The reinforcing structure inside the ring structure connects at least two points on the ring structure, and these two connection points are distributed at intervals along the circumference of the ring structure. This design ensures that the reinforcing structure can effectively disperse and resist forces from all directions, thereby greatly enhancing the overall strength and safety of the vehicle body and providing passengers with a safer and more comfortable riding environment.

[0049] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the reinforcing structure includes a first reinforcing structure 1 and a second reinforcing structure 2, which are symmetrically arranged within the space surrounded by the ring structure. This design is not only aesthetically pleasing but also distributes forces more evenly, improving the stability and strength of the entire ring structure.

[0050] Meanwhile, both ends of the first reinforcing structure 1 and the second reinforcing structure 2 are connected to the ring structure. This connection method ensures that the reinforcing structure can effectively transfer force to all parts of the ring structure, thereby enhancing the rigidity and impact resistance of the entire vehicle body structure. It should be understood that the first reinforcing structure 1 and the second reinforcing structure 2 can also be arranged asymmetrically.

[0051] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the two connection points where the first reinforcing structure 1 connects to the ring structure are the connection points between the B-pillars 3 on both sides and the top cover assembly 5, and the two connection points where the second reinforcing structure 2 connects to the ring structure are the connection points between the B-pillars 3 on both sides and the seat crossbeam 4.

[0052] In the above structure, this connection method not only effectively strengthens the overall strength of the ring structure but also helps improve the torsional stiffness of the entire vehicle body structure, thereby enhancing the overall stability and durability of the vehicle body structure and further improving vehicle safety and ride comfort. In this structure, the upper and lower joints of the B-pillar 3 serve as connection points, connecting the side assemblies on the left and right sides and the sill beam assembly 9. When the vehicle is subjected to roof pressure and rolls over, the compressive force from the roof will be effectively distributed to the left and right side assemblies, sill beams, seat crossbeams 4, and reinforcing structures, effectively preventing damage to the vehicle body structure.

[0053] Still refer to Figure 2 and Figure 3 As shown in this embodiment, the first reinforcing structure 1 and the second reinforcing structure 2 have the same structure. They both include a connecting beam 101 and connecting plates 102 disposed at both ends of the connecting beam 101, and the connecting plates 102 are connected to the ring structure.

[0054] In this structure, the first reinforcing structure 1 and the second reinforcing structure 2 adopt similar construction methods. They both include connecting beams 101 and connecting plates 102. The connecting beams 101 are the main load-bearing components of the reinforcing structure, responsible for transmitting and distributing forces, thereby enhancing the strength and stability of the ring structure. The connecting plates 102 are located at both ends of the connecting beams 101. Their main function is to connect the reinforcing structure to the ring structure, ensuring that they fit together tightly. This tight connection helps to effectively transfer the force of the reinforcing structure to the ring structure, thereby improving the overall performance of the entire vehicle body structure.

[0055] In this embodiment, the connecting beam 101 and the connecting plate 102 are combined together, so that the first reinforcing structure 1 and the second reinforcing structure 2 can form a strong and stable whole, effectively enhancing the strength and durability of the ring structure.

[0056] As a preferred implementation method, such as Figure 3 As shown, each connection point of the annular structure is provided with a mounting plate 6, and the connecting plate 102 and the mounting plate 6 are detachably connected via a first connector 7. Here, the mounting plate 6 provided at the connection points between the first reinforcing structure 1 and the second reinforcing structure 2 and the annular structure provides a more stable and reliable connection interface, enabling the reinforcing structure to be more effectively connected to the annular structure.

[0057] In this embodiment, at the upper part of the B-pillar 3, one end of the mounting plate 6 is connected to the roof assembly 5, and the other end of the mounting plate 6 is connected to the B-pillar 3. At the lower part of the B-pillar 3, one end of the mounting plate 6 is connected to the B-pillar 3, and the other end is connected to the front crossbeam of the seat. The mounting plate 6 can be connected to the various components by means of welding, screwing, plugging, etc.

[0058] In a preferred embodiment, the connection between the connecting plate 102 and the mounting plate 6 is detachable, which makes the installation and removal of the reinforcing structure more convenient and beneficial to vehicle maintenance and repair. In addition, the detachable connection also provides greater flexibility, allowing the position and layout of the reinforcing structure to be adjusted and optimized during the vehicle design phase.

[0059] For example, in this embodiment, a connecting hole is provided on the connecting plate 102 and the mounting plate 6, which runs through both. The first connecting member 7 is specifically a bolt pair passing through the connecting hole. Existing standard parts can be used, which is low-cost. It should be understood that in addition to bolt pair connection, the connecting plate 102 and the mounting plate 6 can also be detachably connected in other ways, such as snap-fit ​​or plug-in connection.

[0060] As a preferred embodiment, reference is still made to... Figure 2 As shown, each connecting beam 101 is designed in an arc shape. The arc shape allows the connecting beam 101 to better disperse and resist forces from all directions, thereby improving the strength and stability of the entire vehicle body structure. The robust and stable vehicle body structure can better absorb and disperse road vibrations and noise, thereby improving driving and riding comfort.

[0061] Furthermore, the curved connecting beams 101 not only have a practical function, but also add a streamlined and dynamic aesthetic effect to the vehicle body. It should be understood that, in addition to being curved, the connecting beams 101 can also be designed in triangular, X-shaped, V-shaped, etc., which can also effectively strengthen the ring structure.

[0062] Continue to refer to Figure 2 As shown, in a preferred embodiment, the middle portions of the two connecting beams 101 are designed to abut against each other in the vertical direction of the vehicle. This allows the first reinforcing structure 1 and the second reinforcing structure 2 to combine to form a more stable and continuous reinforcing structure. This continuity helps to better disperse and resist forces from all directions, more effectively improving the strength and stability of the ring structure, thereby enhancing the overall performance of the vehicle body structure. When the middle portions of the two connecting beams 101 abut against each other, they can jointly resist torsional forces from the vehicle body, thereby increasing the vehicle's torsional stiffness, which helps to improve the vehicle's handling and stability.

[0063] To enhance the reinforcement effect on the ring structure, as a preferred embodiment, the middle of the two connecting beams 101 is detachably connected by a second connector 8, so that the two connecting beams 101 can be easily separated and reconnected when needed. This greatly simplifies the maintenance and replacement process, reduces maintenance costs, and improves maintenance efficiency.

[0064] In the above structure, the detachable connection through the connectors allows it to withstand greater forces and torques, thus ensuring that the two connecting beams 101 can form a stable and reliable reinforced structure when connected, which helps to improve the overall strength and durability of the vehicle body structure.

[0065] In this embodiment, a connecting hole is provided in the middle of the two connecting beams 101, penetrating both. The second connecting member 8 is specifically a bolt pair that passes through the connecting hole, which can be an existing standard part, resulting in low cost. It should be understood that, in addition to using a bolt pair, the contact position of the two connecting beams 101 can also be detachably connected in other forms, such as a plug-in method, a snap-fit ​​method, or a pin method, to achieve the disassembly function.

[0066] In a preferred embodiment, the connecting beam 101 of this embodiment has a cavity that extends along the bending direction of the connecting beam 101. Here, by providing a cavity inside the connecting beam 101, the amount of material used can be significantly reduced, thereby achieving weight reduction, which is of great significance for improving vehicle fuel economy, reducing emissions, and reducing energy consumption.

[0067] At the same time, this structure is not only lightweight, but also ensures that the connecting beam 101 can maintain sufficient strength when subjected to various forces and torques. The presence of the cavity can also increase the bending and torsional stiffness of the connecting beam 101, thereby improving the strengthening effect of the reinforcing structure on the ring structure, and thus improving the overall performance of the vehicle body structure.

[0068] like Figure 4 As shown, in this embodiment, when the vehicle body structure is subjected to top pressure or rollover, the connecting plate 102 and mounting plate 6 at the upper part of the B-pillar 3 transmit the force to the left and right side assemblies, the first reinforcing structure 1, the second reinforcing structure 2, the connecting plate 102 and mounting plate 6 at the lower part of the B-pillar 3, and finally to the seat crossbeam 4 and the floor assembly. For details, please refer to... Figure 4 The thick solid lines and arrows shown in the image indicate the power transmission path. The large arrow in the upper right corner indicates the external force borne by the vehicle body structure, while the small arrows on the thick solid lines indicate the direction of power transmission.

[0069] The vehicle body structure of this embodiment, through the setting of a double arc-shaped reinforcing structure, can achieve the advantages of effective force transmission and bearing between components, so that the vehicle body structure can better withstand forces from all directions, thereby better reinforcing the B ring, and can better solve the problem of insufficient structural strength and rigidity of existing vehicle body structures under top pressure or rollover.

[0070] Example 2

[0072] The vehicle in this embodiment, by applying the body structure as in Embodiment 1, has the same beneficial effects as the body structure in Embodiment 1 compared to the prior art, and will not be described again here.

[0073] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
