Description

Technical Field

[0001] This invention relates to the technical field of vehicle body parts, specifically a vehicle body reinforcement structure and vehicle. Background Technology

[0002] The car body is mainly composed of the chassis, pillars, roof, side panels, and various opening and closing components and exterior trim. The body shell is a rigid spatial frame formed by load-bearing structures such as longitudinal beams, transverse beams, and pillars, together with sheet metal, serving as the mounting base. Its main function is to protect occupants and provide mounting support for other components. A good body structure helps improve vehicle performance and safety. In a collision, the body must absorb impact energy and maintain the integrity of the passenger compartment to ensure occupant survival space.

[0003] In traditional vehicle body structures, the body, side panels, door pillars, doors, and roof together form a rigid space—the passenger compartment. During a collision, crush, or rollover, the body absorbs energy through deformation, striving to maintain the passenger compartment's shape to ensure occupant safety. However, traditional body structures typically lack reinforcement within the passenger compartment, making them prone to deformation under strong impacts. This results in a significant reduction in passenger compartment space, making it difficult to ensure a sufficient safety area.

[0004] Some race cars have support pillars installed inside the passenger compartment to strengthen the body, significantly improving overall rigidity and impact resistance. However, such modifications are costly, complex to install, and usually occupy the rear passenger space (leaving only the front seats), making them difficult to apply directly to ordinary civilian vehicles. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a vehicle body reinforcement structure and a vehicle, solving the problem that existing civilian vehicles lack support and are prone to deformation in the event of an accident.

[0006] According to a first aspect of the present invention, a vehicle body reinforcement structure includes at least one of a transverse support assembly and a longitudinal support assembly, and a vehicle body. The vehicle body includes a roof, a bottom surface, and vehicle pillars connecting the roof and the bottom surface; a seat is provided inside the vehicle body. The longitudinal support assembly includes at least one first support column with adjustable length, the first support column extending along the vertical direction of the vehicle body, one end of the first support column being detachably connected to the top cover, and the other end being detachably connected to the bottom surface or the seat. The lateral support assembly includes at least one second support column with adjustable length, the second support column extending in the left-right direction along the body of the vehicle, one end of the second support column being detachably connected to the body pillar, and the other end being detachably connected to the seat or the first support column.

[0007] A vehicle body reinforcement structure according to an embodiment of the present invention has at least the following beneficial effects: This invention, by setting up lateral and longitudinal support components, utilizes a first support column to provide longitudinal support for the roof, thereby increasing the roof's strength. The first support column also transmits the compressive force on the vehicle body in the vertical direction to the vehicle's underside, seats, and other internal components, dispersing the compressive force. A second support column provides lateral support for the vehicle's pillars, increasing their strength. The second support column also transmits the impact force on the vehicle body in the lateral direction to the seats and other internal components, dispersing the impact force and further buffering it. This comprehensively improves the vehicle body's resistance to deformation, which is beneficial for protecting the passenger compartment space and enhancing safety in the event of a rollover or impact.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0025] The car body mainly consists of the chassis, pillars, roof, side panels, and various opening and closing components and exterior trim. The body shell is a rigid spatial frame composed of load-bearing structures such as longitudinal beams, transverse beams, and pillars, along with sheet metal panels, serving as the mounting base. Its primary function is to protect occupants and provide mounting support for other components. A good body structure helps improve vehicle performance and safety. In a collision, the body must absorb impact energy and maintain the integrity of the passenger compartment to ensure occupant survival space.

[0026] In traditional vehicle body structures, the body, side panels, door pillars, doors, and roof together form a rigid space, namely the passenger compartment. During a collision, crush, or rollover, the body absorbs energy through deformation, striving to maintain the shape of the passenger compartment to ensure occupant safety. However, traditional body structures typically lack reinforcement within the passenger compartment, making them prone to deformation under strong impacts. This results in a significant reduction in passenger compartment space, making it difficult to ensure a sufficient safety area.

[0027] Some racing cars have support pillars installed inside the passenger compartment to strengthen the body, significantly improving overall rigidity and impact resistance. However, such modifications are costly and complex to install, and usually encroach on rear passenger space (leaving only the front seats 140), making them difficult to apply directly to ordinary civilian vehicles.

[0028] To address the aforementioned problems, this invention proposes a vehicle body reinforcement structure and vehicle, which can effectively solve the problems of existing civilian vehicles lacking support and being prone to deformation in accidents.

[0029] refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a vehicle body reinforcement structure and vehicle, which are described in the following embodiments: An embodiment of the present invention provides a vehicle body reinforcement structure including at least one of a transverse support component 300 and a longitudinal support component 200, and a vehicle body 100.

[0030] The main body 100 includes a top cover 110, a bottom surface 120, and a body pillar 130 connecting the top cover 110 and the bottom surface 120. A seat 140 is provided inside the main body 100.

[0031] The longitudinal support assembly 200 includes at least one first support column 210 with adjustable length, the first support column 210 extending along the vertical direction of the vehicle body 100, one end of the first support column 210 being detachably connected to the roof 110, and the other end being detachably connected to the bottom surface 120 or the seat 140; the transverse support assembly 300 includes at least one second support column 310 with adjustable length, the second support column 310 extending along the horizontal direction of the vehicle body 100, one end of the second support column 310 being detachably connected to the vehicle pillar 130, and the other end being detachably connected to the seat 140 or the first support column 210.

[0032] This invention improves the strength of the roof 110 by providing at least one of a transverse support component 300 and a longitudinal support component 200. The first support column 210 provides longitudinal support to the roof 110, thereby increasing its strength. The first support column 210 also transmits the compressive force on the vehicle body 100 in the vertical direction to the vehicle bottom surface 120, the seat 140, and other internal components of the vehicle body 100, thus dispersing the compressive force. The second support column 310 provides transverse support to the vehicle pillar 130, thereby increasing its strength. The second support column 310 also transmits the impact force on the vehicle body 100 in the horizontal direction to the seat 140 and other internal components of the vehicle body 100, dispersing the impact force and further providing a buffering effect. This comprehensively improves the deformation resistance of the vehicle body 100, which is beneficial for protecting the passenger compartment space in the event of a rollover or impact, improving safety. Furthermore, the support column structure effectively reduces the space occupied, ensuring passenger compartment space and reducing installation and modification costs.

[0033] Since the lengths of the first support column 210 and the second support column 310 are adjustable, they can adapt to different sizes of the vehicle body 100, ensuring that the lengths of the first support column 210 and the second support column 310 are exactly matched with the support positions at both ends. When one end is detachably connected to the seat 140, since the position of the seat 140 is generally adjustable, the lengths of the first support column 210 and the second support column 310 can be adjusted to adapt to the adjustment of the seat 140, so as to ensure that they play a supporting role without putting additional pressure on the vehicle body 100 due to being too long or too short.

[0034] On the other hand, the first support column 210 and the second support column 310 are detachably connected and can be flexibly installed and disassembled to adapt to situations where the backrest frame 141 has too large an angle or needs to be folded or flipped. The horizontal support component 300 and the vertical support component 200 can be removed and stored to avoid affecting the folding or flipping of the backrest frame 141 and to avoid affecting the storage space when not needed.

[0035] Furthermore, the first support column 210 is provided with first connectors 220 at both ends. The first support column 210 is detachably connected to the top cover 110, the bottom surface 120, or the seat 140 through the first connectors 220. The first connectors 220 are rotatably adjustable relative to the end of the first support column 210. The second support column 310 is provided with second connectors 320 at both ends. The second support column 310 is detachably connected to the body pillar 130, the seat 140, or the first support column 210 through the second connectors 320. The second connectors 320 are rotatably adjustable relative to the end of the second support column 310. This allows the first connectors 220 and the second connectors 320 to rotate to adapt to the surface of the connected top cover 110, bottom surface 120, or seat 140, thereby improving the connection strength and expanding the applicability of the body reinforcement structure.

[0036] Specifically, a steering adjustment part 330 is provided between the second support column 310 and the second connector 320, and between the first support column 210 and the first connector 220. The steering adjustment part 330 is a ball joint structure with a locking structure. During installation, the steering adjustment part 330 allows the second connector 320 to rotate relative to the second support column 310, thereby fitting against the surface of the installed vehicle body component, such as the top cover 110, bottom surface 120, and seat 140 surface, enhancing the connection strength. After installation, the locking structure fixes the connection angle between the second support column 310 and the second connector 320. The second support column 310 and the second connectors 320 at both ends form a rigid structure, thereby ensuring support strength and stability. In other embodiments, the steering adjustment part 330 can be other structures, such as a multi-directional bearing structure, as long as the angle between the second support column 310 and the second connector 320, and between the first support column 210 and the first connector 220, can be flexibly adjusted.

[0037] Furthermore, the second connector 320 is adjustable in the mounting position of the body pillar 130, seat 140, or first support pillar 210, and the first connector 220 is adjustable in the mounting position of the top cover 110, bottom surface 120, or seat 140. Thus, when the seat 140 needs to be adjusted, the mounting position of the second connector 320 or the first connector 220 can be adjusted to adapt to the adjusted position of the seat 140, flexibly adapting to changes in the seat 140's front-to-back position, height, or backrest frame 141 angle.

[0038] Furthermore, both the first support column 210 and the second support column 310 are provided with length adjustment parts 340. The length adjustment parts 340 are connected to the second support column 310 or the first support column 210 through a transmission connection. By rotating the length adjustment parts 340, the second support column 310 or the first support column 210 can be lengthened or shortened to facilitate length adjustment and optimize the user experience. At the same time, when the first support column 210 and the second support column 310 are adjusted to a suitable length, the length adjustment parts 340 are locked to prevent the length of the first support column 210 and the second support column 310 from changing due to external force or accidental contact, thus ensuring the supporting and reinforcing functions of the first support column 210 and the second support column 310. In some other embodiments, the length adjustment parts 340 may also be in other forms, such as a hydraulic push rod structure, a lead screw motor structure, etc.

[0039] In some embodiments of the present invention, both the first support column 210 and the second support column 310 are provided with an adjustment mode and a locking mode.

[0040] Specifically, when the first support column 210 is in the adjustment mode, the length of the first support column 210 is adjustable, the rotation of the first connector 220 relative to the end of the first support column 210 is adjustable, and the installation position of the first connector 220 is adjustable; when the transverse support assembly 300 is in the locking mode, the length of the first support column 210, the connection angle between the first connector 220 and the first support column 210, and the installation position of the first connector 220 are locked.

[0041] When the second support column 310 is in the adjustment mode, the length of the second support column 310 is adjustable, the rotation of the second connector 320 relative to the end of the second support column 310 is adjustable, and the installation position of the second connector 320 is adjustable; when the transverse support assembly 300 is in the locking mode, the length of the second support column 310, the connection angle between the second connector 320 and the second support column 310, and the installation position of the second connector 320 are locked. The seat 140 includes a backrest frame 141 and a seat cushion frame 142 connected to each other. The seat 140 is provided with an adjustment handle. When the adjustment handle is opened, the position of the seat 140 is adjustable, the connection angle between the backrest frame 141 and the seat cushion frame 142 is adjustable, and the first support column 210 and the second support column 310 connected to the seat 140 are in the adjustment mode. When the adjustment handle is closed, the position of the seat 140 and the connection angle between the backrest frame 141 and the seat cushion frame 142 are locked, and the first support column 210 and the second support column 310 connected to the seat 140 are in the locked mode.

[0042] By controlling the first support column 210 and the second support column 310 to switch between adjustment mode and locking mode, the length of the first support column 210 and the second support column 310, the connection angle with the first connector 220 and the second connector 320, and the installation position of the first connector 220 and the second connector 320 can all be adjusted during the adjustment and installation process. When the first support column 210 and the second support column 310 are installed on the body body 100, if the seat 140 needs to be adjusted, the seat 140 and the body reinforcement structure are adjusted in conjunction. The first support column 210 and the second support column 310 connected to the seat 140 can change simultaneously without disassembly and reinstallation, simplifying the adjustment steps and optimizing the user experience.

[0043] Furthermore, one end of the first support column 210 is detachably connected to the top cover 110, and the other end is detachably connected to the top of the backrest frame 141. The extension direction of the first support column 210 and the backrest frame 141 is consistent. The first support column 210 and the backrest frame 141 form a unified rigid structural whole, supporting the top cover 110 in the vertical direction. The pressure borne by the top cover 110 can be transmitted to the backrest frame 141 through the first support column 210, avoiding uneven force at the connection between the first support column 210 and the backrest frame 141, which would make the connection prone to bending under force when impacted.

[0044] In some other embodiments, one end of the first support column 210 is detachably connected to the top cover 110 and the other end is detachably connected to the seat cushion frame 142. The first support column 210 is located on the side of the seat 140 or penetrates the interior of the seat 140, so that the compressive force borne by the top cover 110 is transmitted to the seat cushion frame 142 through the first support column 210.

[0045] The following are some embodiments of a vehicle body reinforcement structure and a vehicle according to the present invention: Example 1 Reference Figure 1 As shown, one end of the second support column 310 is detachably connected to the backrest frame 141, and the other end is detachably connected to the vehicle body pillar. One end of the first support column 210 is detachably connected to the backrest frame 141, and the other end is detachably connected to the roof 110. The vehicle body pillar is supported by the second support column 310. The impact force on the vehicle body pillar is transmitted to the backrest frame 141 through the second support column 310, thus dispersing the impact force. The roof 110 is supported by the first support column 210 and the backrest frame 141. The compressive force on the roof 110 is transmitted to the backrest frame 141 through the first support column 210, thereby dispersing the compressive force, effectively improving the vehicle body's resistance to deformation, and ensuring the safety of the passenger compartment.

[0046] When the position of the seat 140 or the angle of the backrest frame 141 is adjusted, the first support column 210 and the second support column 310 switch to adjustment mode. The length of the second support column 310, the angle with the second connector 320, and the connection position of the second connector 320 are simultaneously adjustable. When the position of the seat 140 or the angle of the backrest frame 141 is adjusted, the length of the first support column 210, the angle with the first connector 220, and the connection position of the first connector 220 are simultaneously adjustable. After the adjustment is completed, the first support column 210 and the second support column 310 switch to locking mode. The length of the second support column 310, the angle with the second connector 320, and the connection position of the second connector 320 are fixed. The length of the first support column 210, the angle with the first connector 220, and the connection position of the first connector 220 are also fixed, so as to form a stable and reliable reinforcement structure.

[0047] Example 2 Reference Figure 2 As shown, one end of the second support column 310 is detachably connected to the first support column 210, and the other end is detachably connected to the vehicle body pillar. One end of the first support column 210 is detachably connected to the bottom surface 120, and the other end is detachably connected to the top cover 110. The first support column 210 is located beside the seat 140, thereby enhancing the connection strength and reducing the space occupied. The vehicle body pillar is supported by the second support column 310. The impact force on the vehicle body pillar is transmitted to the backrest frame 141 through the second support column 310, dispersing the impact force. The top cover 110 is supported by the first support column 210 and the seat cushion frame 142. The compressive force on the top cover 110 is transmitted to the seat cushion frame 142 through the first support column 210, thereby dispersing the compressive force, effectively improving the vehicle body's resistance to deformation, and ensuring the safety of the passenger compartment.

[0048] When the position of the seat 140 or the angle of the backrest frame 141 is adjusted, the first support column 210 and the second support column 310 switch to adjustment mode. The length of the second support column 310, the angle with the second connector 320, and the connection position of the second connector 320 are simultaneously adjustable. When the position of the seat 140 or the angle of the backrest frame 141 is adjusted, the length of the first support column 210, the angle with the first connector 220, and the connection position of the first connector 220 are simultaneously adjustable. After the adjustment is completed, the first support column 210 and the second support column 310 switch to locking mode. The length of the second support column 310, the angle with the second connector 320, and the connection position of the second connector 320 are fixed. The length of the first support column 210, the angle with the first connector 220, and the connection position of the first connector 220 are also fixed, so as to form a stable and reliable reinforcement structure.

[0049] Example 3 Reference Figure 3As shown, one end of the second support column 310 is detachably connected to the backrest frame 141, and the other end is detachably connected to the vehicle body pillar. One end of the first support column 210 is detachably connected to the seat cushion frame 142, and the other end is detachably connected to the roof 110. The vehicle body pillar is supported by the second support column 310. The impact force on the vehicle body pillar is transmitted to the backrest frame 141 through the second support column 310, thus dispersing the impact force. The roof 110 is supported by the first support column 210. The compressive force on the roof 110 is transmitted to the bottom surface 120 through the first support column 210, thereby dispersing the compressive force, effectively improving the vehicle body's resistance to deformation, and ensuring the safety of the passenger compartment.

[0050] When the position of the seat 140 or the angle of the backrest frame 141 is adjusted, the first support column 210 and the second support column 310 switch to adjustment mode. The length of the second support column 310, the angle with the second connector 320, and the connection position of the second connector 320 are simultaneously adjustable. When the position of the seat 140 or the angle of the backrest frame 141 is adjusted, the length of the first support column 210, the angle with the first connector 220, and the connection position of the first connector 220 are simultaneously adjustable. After the adjustment is completed, the first support column 210 and the second support column 310 switch to locking mode. The length of the second support column 310, the angle with the second connector 320, and the connection position of the second connector 320 are fixed. The length of the first support column 210, the angle with the first connector 220, and the connection position of the first connector 220 are also fixed, so as to form a stable and reliable reinforcement structure.
