DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.

[0043] REFERENCE Figures 1 to 8 As shown in the figure, the first aspect of the embodiment of the present application provides a vehicle body structure, which comprises a vehicle body frame and a first pipe body part 4 in a tubular structure; the vehicle body frame comprises two groups of connecting column assemblies 1, a floor part 2 and a storage assembly 3, the floor part 2 is installed with the connecting column assemblies 1 on both sides along the vehicle transverse direction, the storage assembly 3 is connected to the two groups of connecting column assemblies 1 at both ends and is arranged spaced apart from the floor part 2; the first pipe body part 4 comprises a side mounting part 41 and a support part 42, the side mounting part 41 is connected to the connecting column assemblies 1 at both ends, and the support part 42 is connected to the side mounting part 41 and supported between the floor part 2 and the storage assembly 3.

[0044] Specifically, the frame of the vehicle is a structure that mainly bears the impact force when the vehicle is subjected to a collision, and the rigidity, tensile strength, Young's modulus, etc. of the frame of the vehicle need to meet certain requirements so that the frame of the vehicle can bear the impact of the vehicle collision without injuring the driver and passengers; while the frame of the vehicle itself is limited by the manufacturing material and size, and needs to be reinforced to improve the structural strength of the frame of the vehicle, and sheet metal parts are usually attached and connected to the frame of the vehicle, so that the sheet metal parts can share the impact force borne by the frame of the vehicle; and the rear space of the vehicle is large and is also prone to collision, and the sheet metal parts are mostly arranged in the frame of the rear of the vehicle. However, the sheet metal parts need to be adapted to the shape and size of the frame of the vehicle, and a custom mold is needed to manufacture sheet metal parts that meet the shape and size requirements, resulting in complex process, long production cycle and high cost. The cost of sheet metal parts as a reinforcing structure also increases the overall process difficulty of manufacturing vehicles.

[0045] However, the vehicle body structure provided by the present application sets the first pipe body part 4 in the vehicle body frame, the first pipe body part 4 is a tubular structure, and the first pipe body part 4 is supported between the storage assembly 3 and the floor part 2 to effectively disperse stress, reduce local deformation, and maintain the stability of the vehicle body structure, thereby improving the structural strength of the vehicle body frame; the tubular structure of the first pipe body part 4 can be adapted to the space inside the vehicle body frame by simple cutting and splicing, and the manufacturing process of the first pipe body part 4 is simple and does not need to be customized. Mold; the tubular structure of the first pipe body part 4 can not only improve the structural strength of the vehicle frame, but also reduce the manufacturing cost and manufacturing process difficulty of the vehicle.

[0046] The direction opposite to the front and rear of the vehicle is the longitudinal direction of the vehicle, and when the vehicle is placed on a horizontal plane, the vertical direction is the height direction of the vehicle, and the direction perpendicular to the longitudinal direction and the vertical direction of the vehicle is the lateral direction of the vehicle; the connecting column assembly 1 is connected to one side of the floor part 2, and the floor part 2 is connected to the mutually symmetrical connecting column assemblies 1 on both sides along the lateral direction of the vehicle, so that the floor part 2, the two connecting column assemblies 1 and the roof are connected to form a vehicle body frame.

[0047] Vehicles typically have a chassis, roof, and multiple connecting pillars. These pillars connect the roof and chassis, forming the vehicle's frame. These pillars are usually named A-pillar, B-pillar, C-pillar, and D-pillar along the longitudinal direction of the vehicle from front to rear. A portion of the chassis can serve as a floor component 2. The connecting pillar assemblies 1 on both sides of the floor component 2 can optionally include A-pillars, B-pillars, C-pillars, and D-pillars. The A-pillars, B-pillars, C-pillars, and D-pillars of the connecting pillar assemblies 1 on both sides of the floor component 2 are symmetrically arranged laterally, meaning the vehicle frame has two A-pillars, two B-pillars, two C-pillars, and two D-pillars symmetrically arranged laterally. The A-pillars are located at the front hood, the B-pillars are in the middle of the vehicle, the C-pillars are typically located at the rear wheels, and the bottom of the C-pillar is usually connected to the rear wheel arch, with the rear wheels housed within the rear wheel arch. The D-pillars are typically located on the side of the C-pillar closest to the rear of the vehicle.

[0048] This application Figures 1 to 8 The connecting pillar assembly 1 shown is part of multiple connecting pillars of the vehicle. The connecting pillar assembly 1 is mainly the C-pillar and D-pillar near the rear of the vehicle. The first tubular component 4 is set at the C-pillar of the vehicle. The storage component 3 is a bracket structure set in the vehicle frame, and objects can be placed on the storage component 3. In some models, the storage component 3 is set on the side of the rear seats near the rear of the vehicle. The storage component 3 is separated from the chassis. The space enclosed by the storage component 3, the chassis and the rear seats forms the trunk. The storage component 3 can be a plate structure or a frame structure on the same plane, so that items can be placed on the storage component 3 and the storage component 3 can divide the interior space of the vehicle.

[0049] The aforementioned side mounting portion 41 can be selected as a rectangular frame or other shape frame structure formed by connecting multiple tubes. The frame structure extends longitudinally along the vehicle, and both ends of the frame structure are connected to the connecting column assembly 1, so that the frame structure can provide support for the connecting column assembly 1 longitudinally in the vehicle and can transfer the force on the connecting column assembly to the floor piece 2.

[0050] The aforementioned support portion 42 can be selected as a conical structure formed by multiple vertically arranged tubes. The tip of the conical structure is connected to the storage component 3, and the bottom of the conical structure is connected to the floor component 2, so that the conical structure is supported between the storage component 3 and the floor component 2. Alternatively, the support portion 42 can be selected as a vertically arranged tube, with both ends of the tube connected to the storage component 3 and the floor component 2 respectively, so that the tube supports the storage component 3.

[0051] The aforementioned support part 42 can be connected to the storage component 3 and the floor component 2 by welding, or it can be connected by bolts or riveting.

[0052] The support part 42 and the side mounting part 41 can be spaced apart from each other in the vehicle transverse direction, a connecting pipe 43 extending in the vehicle transverse direction is arranged between the support part 42 and the side mounting part 41, and the two ends of the connecting pipe 43 are connected to the support part 42 and the side mounting part 41 respectively. Of course, a part of the side mounting part 41 can also extend towards the support part 42 to be connected to the support part 42, so that the support part 42 and the side mounting part 41 are integrated as a whole to improve the structural stability of the first pipe body 4 as a whole.

[0053] The side mounting part 41 provides support to the connecting column assembly 1 in the vehicle longitudinal direction, thereby improving the structural stability of the vehicle body frame; the support part 42 is connected to the side mounting part 41, so that the support part 42 and the side mounting part 41 can jointly bear the impact force, thereby improving the structural stability of the first pipe body 4; the support part 42 can form a support between the storage assembly 3 and the floor member 2, thereby improving the structural stability of the storage assembly 3; the cooperation of the side mounting part 41 and the support part 42 enables the stress on the connecting column assembly 1 and the storage assembly 3 to be transmitted to the floor member 2, so that the first pipe body 4 can disperse the stress at multiple positions of the vehicle frame, thereby improving the structural strength of the vehicle frame as a whole.

[0054] The first pipe body 4 can be formed by connecting a plurality of pipes to each other, so that the first pipe body 4 has a tubular structure; the pipes in the first pipe body 4 can be square pipes, and of course can also be round pipes, and the pipes of the first pipe body 4 are all hollow pipe structures; compared with sheet metal members, the load bearing capacity of the pipe structure is stronger than that of the sheet metal member, so that the first pipe body 4 can effectively disperse stress and reduce local deformation to maintain the stability of the vehicle body structure. Moreover, the sheet metal member is prone to small reciprocating deformation during vehicle driving, which can cause fatigue fracture of the sheet metal member; the pipe structure has high structural strength and is not prone to deformation, and has a longer service life than the sheet metal member. The structural strength of the sheet metal member is relatively low, so when the sheet metal member is used as a reinforcing structure, the sheet metal member needs to have a relatively thick thickness to meet the requirement of structural strength. However, the pipe structure has high structural strength, and the pipe can use less material to achieve the same structural strength compared with the sheet metal member, so the first pipe body 4 required can be made of less weight material, and the use of the first pipe body 4 in the vehicle can reduce the overall weight of the vehicle, thereby improving the fuel economy, acceleration performance and handling performance of the vehicle.

[0055] The design of using the pipe body as the first pipe body piece 4 is flexible, and various lap joints and combinations can be made based on a key force transmission channel layout to achieve optimal space utilization, thereby releasing more in-vehicle passenger space. The standard pipe body is cut to form pipe bodies of different sizes, and the pipe bodies of different sizes are spliced and welded with each other to form the first pipe body piece 4 that can adapt to the internal space of the vehicle frame. The machining process of the pipe body is relatively simple compared with sheet metal, and does not need a customized mold and a high-cost process such as casting and stamping. The first pipe body piece 4 can be manufactured through processes such as cutting, bending, and welding, which is conducive to reducing the production cost of the vehicle.

[0056] The first pipe body piece 4 is made of a pipe body to have a tubular structure, and the first pipe body piece 4 and the connecting column assembly 1 can also be made of pipe bodies. Of course, the first pipe body piece 4, the storage assembly 3, and the connecting column assembly 1 can also be made of pipe bodies.

[0057] The vehicle body structure provided in the embodiment is used as follows: The first pipe body piece 4 is installed on the connecting column assembly, the side mounting portion 41 is connected with the connecting column assembly 1, and the support portion 42 is installed on the side mounting portion 41 to be supported between the storage assembly 3 and the floor piece 2. When the vehicle collides, the impact force received by the connecting column assembly 1 can be transmitted to the storage assembly 3 and the support portion 42, and the impact force on the storage assembly 3 is transmitted to the floor piece 2 through the support portion 42. The impact force on the connecting column assembly 1 is also transmitted to the floor piece 2 through the side mounting portion 41 and the support portion 42, so that the first pipe body piece 4 disperses the impact force received by the vehicle body frame, and the first pipe body piece 4 improves the structural strength of the vehicle body frame as a whole.

[0058] The vehicle body structure provided by the embodiments of the present application comprises a vehicle body frame and a first tubular member 4 in a tubular structure; the vehicle body frame comprises two groups of connecting column assemblies 1, a floor member 2 and a storage assembly 3, the floor member 2 is provided with the connecting column assemblies 1 on both sides in the transverse direction of the vehicle, the storage assembly 3 is connected to the two groups of connecting column assemblies 1 at both ends and is arranged in a spaced manner with the floor member 2; the first tubular member 4 comprises a side mounting portion 41 and a supporting portion 42, the side mounting portion 41 is connected to the connecting column assemblies 1 at both ends, and the supporting portion 42 is connected to the side mounting portion 41 and is supported between the floor member 2 and the storage assembly 3. The side mounting portion 41 can conduct the impact force received by the connecting column assemblies 1, and the supporting portion 42 can form a support between the storage assembly 3 and the floor member 2, so that the impact force on the connecting column assemblies 1 and the storage assembly 3 can be conducted to the floor member 2 through the side mounting portion 41 and the supporting portion 42; the first tubular member 4 can effectively disperse stress, reduce local deformation and maintain the stability of the vehicle body structure, thereby improving the structural strength of the vehicle body frame; the tubular member can be cut and assembled to form the side mounting portion 41 and the supporting portion 42 mounted in the vehicle frame, so that the first tubular member 4 does not need to be customized with a mold, the manufacturing cost and manufacturing difficulty of the vehicle reinforcing structure are reduced, the first tubular member 4 can improve the structural strength of the vehicle frame and reduce the manufacturing cost and manufacturing process difficulty of the vehicle.

[0059] Referring to Figures 1 to 3 and Figures 5 to 8 In some embodiments, the connecting column assembly 1 comprises a rear connecting column 11 and a tail connecting column 12 arranged in the longitudinal direction of the vehicle, the bottom of the rear connecting column 11 and the tail connecting column 12 is connected to the floor member 2, one end of the storage assembly 3 is connected to the tail connecting column 12 on the same side, and the two ends of the side mounting portion 41 are connected between the rear connecting column 11 and the tail connecting column 12.

[0060] In this way, the side mounting portion 41 can form a support between the rear connecting column 11 and the tail connecting column 12 to share the stress on the rear connecting column 11 and the tail connecting column 12, thereby improving the structural strength of the connecting column assembly 1.

[0061] Specifically, the tail connecting column 12 is arranged in a spaced manner with the rear connecting column 11 in the longitudinal direction of the vehicle, the rear connecting column 11 can be selected as a column structure at the position of the rear wheel of the vehicle, that is, the rear connecting column 11 is the C column of the vehicle; the tail connecting column 12 is a column structure on the side close to the tail of the rear connecting column 11, that is, the tail connecting column 12 is the D column of the vehicle. The top end of the tail connecting column 12 and the rear connecting column 11 is connected to the roof, and the bottom end of the tail connecting column 12 and the rear connecting column 11 is connected to the floor member 2; the floor member 2 can be selected as a structural member close to the tail part of the chassis, the floor member 2 is a mounting platform for internal parts of the vehicle, and the storage assembly 3 and the floor member 2 are spaced in the height direction of the vehicle, so that the space between the storage assembly 3 and the floor member 2 in the height direction of the vehicle can form a trunk.

[0062] The side mounting portion 41 can be a frame structure or a single tube structure, and extends in the longitudinal direction of the vehicle, so that the two ends of the side mounting portion 41 are connected to the rear connecting column 11 and the tail connecting column 12, respectively, so that the side mounting portion 41 can provide support for the rear connecting column 11 and the tail connecting column 12 in the longitudinal direction of the vehicle, so that the side mounting portion 41 can disperse the force acting on the rear connecting column 11 and the tail connecting column 12.

[0063] The storage assembly 3 is connected between the two tail connecting columns 12, so that the storage assembly 3 can provide stability for the relative position between the two tail connecting columns 12, and can transmit the impact force on one tail connecting column 12 to the other tail connecting column 12 through the storage assembly 3, so as to improve the structural strength of the two tail connecting columns 12.

[0064] Referring to Figures 1 to 6 In some embodiments, the connecting column assembly 1 includes a wheel cover plate 13 connected to the rear connecting column 11, the side mounting portion 41 is arranged around the wheel cover plate 13, and the wheel cover plate 13 is at least partially connected to the side mounting portion 41.

[0065] In this way, the side mounting portion 41 can surround the wheel cover plate 13, so that the stress at each position of the wheel cover plate 13 can be transmitted to the side mounting portion 41, so that the side mounting portion 41 can effectively disperse the stress of the connecting column assembly 1 at the wheel cover plate 13, avoid the wheel cover plate 13 and the rear connecting column 11 from being separated, and improve the structural strength of the connecting column assembly 1.

[0066] The wheel cover plate 13 is arranged at a position close to the floor member 2 of the rear connecting column 11, and can include an arc-shaped main plate body and two side plate portions opposite in the lateral direction of the vehicle. The two side plate portions are connected to the main plate body, and the opening of the cover structure formed by the two side plate portions and the main plate body is arranged downward, so that a part of the wheel is arranged in the wheel cover plate 13, and the wheel is exposed to the bottom side of the chassis of the vehicle through the opening of the wheel cover plate 13. The wheel cover plate 13 is usually provided with a transmission shaft and the like structure, which has a smaller space in the lateral direction of the vehicle and a larger space in the vertical direction, so as to accommodate the first tube member 4.

[0067] The wheel cover plate 13 is connected to the rear connecting column 11, and is also connected to the floor member 2, so that the vehicle frame has more connection points at the wheel cover plate 13 and has lower structural strength. The first tube member 4 arranged at the wheel cover plate 13 can improve the structural strength of the wheel cover plate 13, so as to avoid the connection between the wheel cover plate 13 and the vehicle frame from cracking when the vehicle collides.

[0068] The wheel cover plate 13 is provided with multiple connection points with the vehicle frame and is prone to breakage. The side mounting portion 41 is arranged around the wheel cover plate 13, and stress on the wheel cover plate 13 is transmitted to the side mounting portion 41 in multiple directions, so that the side mounting portion 41 can share the stress on the wheel cover plate 13, thereby improving the structural strength of the connection column assembly 1 at the wheel cover plate 13.

[0069] The side mounting portion 41 can include a first pipe body extending in the vehicle longitudinal direction and two second pipe bodies extending in the vehicle height direction. The two ends of the first pipe body are connected to the rear connection column 11 and the tail connection column 12. The first pipe body is arranged on the top side of the wheel cover plate 13 and connected to the top side edge of the wheel cover plate 13. The two second pipe bodies are connected to the first pipe body and arranged on both sides of the wheel cover plate 13 in the vehicle longitudinal direction.

[0070] Of course, the side mounting portion 41 can also be a frame structure formed by multiple pipe bodies. The frame structure is arranged around the wheel cover plate 13, and the edge of the wheel cover plate 13 is connected to the frame structure, so that the side mounting portion 41 can disperse the stress on the wheel cover plate 13.

[0071] Referring to Figures 1 to 6 In some embodiments, the side mounting portion 41 includes a first pipe body 411 and two second pipe bodies 412.

[0072] In this way, the first pipe body 411 improves the structural stability of the rear connection column 11 and the tail connection column 12 in the vehicle longitudinal direction. The force on the rear connection column 11 and the tail connection column 12 is transmitted to the first pipe body 411, and the force on the first pipe body 411 is transmitted to the floor member 2 through the second pipe bodies 412, so that the side mounting portion 41 can disperse the stress on the connection column assembly 1 and improve the structural strength of the connection column assembly 1. The floor member 2, the first pipe body 411, and the two second pipe bodies 412 form a frame structure around the wheel cover plate 13, so that the side mounting portion 41 can reasonably utilize the space around the wheel cover plate 13. The frame structure around the wheel cover plate 13 can effectively disperse the stress on the connection column assembly 1 at the wheel cover plate 13, improve the structural strength of the connection column assembly 1 at the wheel cover plate 13, and avoid damage to the vehicle wheels during a vehicle collision, which can cause the vehicle to lose control and the wheels to fly out, causing secondary injuries.

[0073] Specifically, the first pipe 411 is a hollow pipe body, the first pipe 411 extends along the vehicle longitudinal direction, two ends of the first pipe 411 are connected with the rear connecting column 11 and the tail connecting column 12 respectively, and the part of the wheel cover plate 13 close to the inside of the vehicle body frame is protruded towards the inside of the vehicle body frame, the first pipe 411 can avoid the wheel cover plate 13 at the top side of the wheel cover plate 13, and the space in the vehicle body frame is reasonably utilized.

The two ends of the rear support pipe 14 are connected to the first pipe 411 and the floor member 2, respectively. Thus, the upper side beam pipes and the rear support pipe 14 form a columnar structure on the side of the rear connection column 11 close to the tail of the vehicle, so that the upper side beam pipes and the rear support pipe 14 together with the floor member 2 enclose a space on the side close to the tail of the vehicle for the rear seats of the vehicle.

The two first pipes 411 extend along the longitudinal direction of the vehicle on the closed frame structure, and the two first pipes 411 connect the closed rear frame structure and the two rear connection columns 11, so as to form a frame structure similar to a box. When the vehicle is subjected to a collision in any direction, the impact force of the collision is transmitted to the box structure, so that the pipes of the box structure disperse the stress, thereby reducing the deformation of the entire vehicle frame.
