Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to vehicle body structure and vehicles. Background Technology

[0002] The vehicle has a body, which includes a floor assembly and side panel assemblies. In the prior art, the floor assembly and side panel assemblies need to be overlapped during the production of the vehicle body.

[0003] However, when the floor assembly and side panel assembly are overlapped, the side panels of the floor assembly are prone to falling off due to the weight because they lack support in the height direction. Utility Model Content

[0004] In view of this, this application provides a vehicle body structure and a vehicle to solve the problem that when the floor assembly and the side panel assembly are overlapped, the side panels of the floor assembly are prone to fall off due to weight.

[0005] On one hand, this application provides a vehicle body structure for a vehicle, including: a floor assembly including a rear longitudinal beam and a side panel, the rear longitudinal beam extending along the vehicle's longitudinal direction; a side panel assembly disposed on one side of the rear longitudinal beam along the vehicle's left-right direction, the side panel assembly being spaced apart from the rear longitudinal beam, the side panel being connected between the rear longitudinal beam and the side panel assembly; and a support member disposed on the side of the rear longitudinal beam facing the side panel assembly, the side panel being supported by the support member.

[0006] In some embodiments, the support member includes a connecting portion and a supporting portion, the connecting portion being used to connect with the rear longitudinal beam, and the supporting portion being used to support the side plate.

[0007] In some embodiments, the connecting portion is formed as a connecting plate extending along the vehicle height direction, and the connecting plate is opposite to and fitted to the rear longitudinal beam along the left-right direction of the vehicle.

[0008] In some embodiments, the rear longitudinal beam has a first connecting hole, and the connecting part has a second connecting hole; the rear longitudinal beam and the connecting part are connected by fasteners passing through the first connecting hole and the second connecting hole.

[0009] In some embodiments, there are multiple second connection holes spaced apart along the vehicle height direction, and any one of the multiple second connection holes is opposite to the first connection hole and connected by the fastener to adjust the height of the support.

[0010] In some embodiments, the support portion is formed as a support plate parallel to the side plate, the support plate extending in the left-right direction of the vehicle and spaced apart from the side assembly, the side plate being supported by the rear longitudinal beam and the support plate, and the side plate being welded to the support plate.

[0011] In some embodiments, the side plate is provided with a vertically extending connecting flange, which is attached to and welded to the side panel assembly.

[0012] In some embodiments, the width of the welding area between the connecting flange and the side panel assembly is less than or equal to 16 mm along the vehicle height direction.

[0013] In some embodiments, the vehicle body structure also includes a sealant applied to the mating gap between the connecting flange and the side panel assembly to seal the mating gap.

[0014] On the other hand, this application also provides a vehicle that includes the body structure described above.

[0015] The vehicle body structure and vehicle provided in this application, by placing a support member on the side of the rear longitudinal beam facing the side assembly, supports the side panel to the support member, thereby providing support to the side panel and preventing it from sagging when the floor assembly and side assembly overlap, especially preventing the portion of the side panel near the side assembly from sagging; thus preventing misalignment between the floor assembly and side assembly. At the same time, the support member also enhances the load-bearing capacity of the floor assembly to a certain extent. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0029] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0030] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0031] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0032] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0034] The vehicle has a body, which includes a floor assembly and side panel assemblies. In the prior art, during the production of the vehicle body, the side panels of the floor assembly and the side panel assemblies need to be overlapped. However, when the floor assembly and the side panel assemblies are overlapped, the side panels of the floor assembly are prone to falling off due to their weight.

[0035] It should be noted that the side panels of the floor assembly have a certain width. When the floor assembly and side panel assemblies overlap, and before they are fully assembled, the portion of the side panel closest to the side panel assembly is prone to sagging due to this width and gravity. For example, the overlapping surfaces of the side panel and side panel assemblies extend along the vehicle's height. When the floor assembly and side panel assemblies overlap, the side panel is prone to sagging due to gravity. It should be noted that after the side panel sagging, it will cause misalignment between the side panel and the side panel assembly. This misalignment increases the error between the side panel and the side panel assembly and affects the subsequent application of adhesive for sealing between the side panel and the side panel assembly, potentially affecting the sealing effect in severe cases.

[0036] To address the aforementioned issues, this application provides a vehicle body structure and a vehicle that incorporates a support member positioned on the side of the rear longitudinal beam facing the side panel assembly. The side panel is supported by this support member, providing lifting support to the side panel. This prevents the side panel from sagging, particularly the portion of the side panel closest to the side panel assembly, when the floor assembly and side panel assembly overlap, thus avoiding misalignment between the side panel and the side panel assembly. Furthermore, the support member also enhances the load-bearing capacity of the floor assembly to a certain extent.

[0037] Reference Figures 1 to 5 In the description of this application, the vehicle's longitudinal direction (i.e., the length direction of the vehicle) refers to the direction parallel to the X direction of the coordinate system; the vehicle's height direction refers to the direction parallel to the Z direction of the coordinate system, where the positive direction of the Z direction is the upward direction of the height; and the vehicle's lateral direction (i.e., the width direction of the vehicle) refers to the direction parallel to the Y direction of the coordinate system.

[0038] refer to Figure 1 and Figure 2On the one hand, this application provides a vehicle body structure 1000 for use in vehicles. It should be noted that the vehicle in this application can refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to vehicle type, the automobile in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0039] Reference Figure 1 and Figure 2 The vehicle body structure 1000 includes a floor assembly 100, a side panel assembly 200, and support members 300. It should be noted that the floor assembly 100 is located at the bottom of the passenger compartment and / or luggage compartment of the vehicle. The floor assembly 100 includes a rear longitudinal beam 110 and a side panel 120. This embodiment does not limit the connection method between the rear longitudinal beam 110 and the side panel 120; for example, the rear longitudinal beam 110 and the side panel 120 can be connected by welding, or they can be connected by existing fasteners such as rivets or bolts, or they can be connected by a combination of welding and fasteners.

[0040] Reference Figure 1 and Figure 2 The rear longitudinal beam 110 extends along the longitudinal direction of the vehicle. The side panel assembly 200 is located on one side of the rear longitudinal beam 110 along the left-right direction of the vehicle. It should be noted that the side panel assembly 200 refers to the collective name of large coverings and structural components constituting the side of the vehicle body. The side panel assembly 200 is not only an exterior covering but also an important component of the vehicle body's strength and rigidity. This embodiment does not limit the specific shape of the side panel assembly 200. For example, the side panel assembly 200 includes an inner panel 210 located inside the vehicle body and an outer panel 220 located outside the vehicle body, connected by welding. The side panel assembly 200 may also have an intermediate structural member between the inner panel 210 and the outer panel 220 to enhance its strength.

[0041] Reference Figure 1 and Figure 2 The side panel assembly 200 and the rear longitudinal beam 110 are arranged at intervals, and the side plate 120 is connected between the rear longitudinal beam 110 and the side panel assembly 200. This embodiment does not limit the specific shape of the side plate 120. For example, the side plate 120 can be a metal plate of a certain thickness. The side plate 120 can also be strengthened by using sheet metal processes to add protrusions or ribs, and the side plate 120 can also be strengthened by welding some structural auxiliary structures.

[0042] Reference Figure 1 and Figure 2The support member 300 is located on the side of the rear longitudinal beam 110 facing the side assembly 200, and the side plate 120 is supported by the support member 300. In the embodiments of this application, the specific structure and number of the support member 300 are not limited, as long as the support member 300 can play a supporting role between the rear longitudinal beam 110 and the side plate 120.

[0043] For example, the support member 300 can be a triangular structure, which can be formed by connecting three rods or pipes end to end, or it can be a triangular metal plate. One side of the triangle can be fixed to the rear longitudinal beam 110 by welding and / or fasteners, and this side of the triangle extends along the height direction of the vehicle; the other side of the triangle can be fixed to the side plate 120 by welding and / or fasteners, so as to support the side plate 120 through this side of the triangle; this side of the triangle used to support the side plate 120 can also be connected to the side plate 120 by simply abutting. Multiple such triangular support members 300 can be provided, and the multiple such triangular support members 300 are arranged sequentially at intervals along the front-rear direction of the vehicle.

[0044] Reference Figure 1 and Figure 2 For example, the support member 300 can also be a sheet metal bend extending in the longitudinal direction of the vehicle. The sheet metal bend has a first side for connection to the rear longitudinal beam 110 and a second side for connection to the side plate 120. The first side faces the rear longitudinal beam 110, and the rear longitudinal beam 110 is connected to the first side by welding and / or fasteners; the side plate 120 faces the second side, and the side plate 120 is connected to the second side by welding and / or fasteners, or simply by abutting. Furthermore, a rib can be provided between the first and second sides to enhance the strength of the support member 300.

[0045] For example, the support member 300 can also be a tube arranged along the length of the vehicle, with the rear longitudinal beam 110 and the side plate 120 both connected to the outer circumference of the tube to support the side plate 120. The tube can be connected to the rear longitudinal beam 110 by welding and / or fasteners; the tube can also be connected to the side plate 120 by welding and / or fasteners, or the tube can be connected to the side plate 120 by simply abutting.

[0046] For example, the support member 300 can also be a plate or frame that is laid flat on the bottom of the side plate 120.

[0047] Understandably, the number of support members 300 can be one or more. When there is only one support member 300, it extends along the front-rear direction of the vehicle. When there are multiple support members 300, they are arranged at intervals along the front-rear direction of the vehicle.

[0048] Reference Figure 1 and Figure 2 The vehicle body structure 1000 provided in the embodiments of this application includes a floor assembly 100, a side panel assembly 200, and a support member 300. By providing the support member 300, which is located on the side of the rear longitudinal beam 110 facing the side panel assembly 200, the side panel 120 is supported by the support member 300. This provides support to the side panel 120, preventing it from sagging when the floor assembly 100 and the side panel assembly 200 overlap, especially preventing the portion of the side panel 120 near the side panel assembly 200 from sagging, thus avoiding misalignment between the side panel 120 and the side panel assembly 200. Simultaneously, the support member 300 also enhances the load-bearing capacity of the floor assembly 100 to a certain extent.

[0049] Reference Figure 2 and Figure 3 In some embodiments, the support member 300 includes a connecting portion 310 and a supporting portion 320. The connecting portion 310 is used to connect with the rear longitudinal beam 110, and the supporting portion 320 is used to support the side plate 120.

[0050] The embodiments of this application do not limit the specific connection method between the connecting portion 310 and the supporting portion 320. For example, the supporting member 300, including the connecting portion 310 and the supporting portion 320, can be a sheet metal bent part, with the connecting portion 310 and the supporting portion 320 being the two sides of this sheet metal bent part. The supporting member 300, including the connecting portion 310 and the supporting portion 320, can also be a welded part manufactured by welding. The connecting portion 310 and the supporting portion 320 can be directly connected, or they can be connected through an intermediate connector. In the supporting member 300, including the connecting portion 310 and the supporting portion 320, features such as ribs can be provided between the connecting portion 310 and the supporting portion 320 to enhance the strength of the supporting member 300.

[0051] The embodiments of this application do not limit the specific shape of the connecting part 310 and the supporting part 320. For example, the connecting part 310 and / or the supporting part 320 can be plate-shaped, frame-shaped, or block-shaped.

[0052] The embodiments of this application do not limit the number of connecting portions 310. There may be one connecting portion 310, which extends along the longitudinal direction of the vehicle. Alternatively, there may be multiple connecting portions 310, arranged sequentially at intervals along the length of the vehicle. The embodiments of this application do not limit the connection method between the connecting portion 310 and the rear longitudinal beam 110. For example, the connecting portion 310 and the rear longitudinal beam 110 may be fixedly connected by welding and / or fasteners.

[0053] The embodiments of this application do not limit the number of support portions 320. For example, there may be one support portion 320, which extends along the front-rear direction of the vehicle; there may also be multiple support portions 320, which are sequentially spaced along the front-rear direction of the vehicle. The embodiments of this application do not limit the connection method between the support portion 320 and the side plate 120. For example, the support portion 320 and the side plate 120 may be fixedly connected by welding and / or fasteners; the support portion 320 and the side plate 120 may also be connected by simply abutting against each other.

[0054] Reference Figure 1 and Figure 2 Understandably, the support member 300 is provided with a connecting part 310 to facilitate positioning and connection with the rear longitudinal beam 110; the support member is provided with a support part 320 to facilitate positioning and connection with the side plate 120.

[0055] Reference Figure 2 and Figure 3 In some embodiments, the connecting portion 310 is formed as a connecting plate extending along the vehicle height direction, and the connecting plate is opposite to and fitted to the rear longitudinal beam 110 along the left-right direction of the vehicle.

[0056] The embodiments of this application do not limit the connection method between the connecting plate and the rear longitudinal beam 110. The connecting plate and the rear longitudinal beam 110 can be connected by welding and / or fasteners. The embodiments of this application do not limit the number of connecting plates. There can be one connecting plate, which extends along the front-rear direction of the vehicle. There can also be multiple connecting plates, which are arranged at intervals along the front-rear direction of the vehicle.

[0057] Reference Figure 1 and Figure 2 It should be noted that the side plate 120 is set roughly horizontally. Since the connecting plate extends along the height of the vehicle, an angle is formed between the side plate 120 and the connecting plate. This angle helps to enhance the support effect of the support member 300 on the side plate 120.

[0058] Reference Figure 2 and Figure 3 In one embodiment, the rear longitudinal beam 110 has a first connecting hole 111, and the connecting portion 310 has a second connecting hole 311. The rear longitudinal beam 110 and the connecting portion 310 are connected by fasteners 400 passing through the first connecting hole 111 and the second connecting hole 311. Exemplarily, the fastener can be a rivet or a bolt. When the fastener is a rivet, the first connecting hole 111 and the second connecting hole 311 are used to pass through the rivet. When the fastener is a bolt, the second connecting hole 311 is used to pass through the bolt, and the first connecting hole 111 has an internal thread that mates with the bolt.

[0059] For example, the number of connecting portions 310 can be one, extending along the length direction of the vehicle, and the connecting portion 310 can have one second connecting hole 311; the connecting portion 310 can also have multiple second connecting holes 311, and the multiple second connecting holes 311 extend along the longitudinal direction of the vehicle. The number of connecting portions 310 can be multiple; the second connecting hole 311 can be provided in one of the multiple connecting portions 310, or in two or more of the multiple connecting portions 310, or in all of the multiple connecting portions 310. The number and position of the first connecting holes 111 on the rear longitudinal beam 110 correspond to the number and position of the second connecting holes 311. It is understood that aligning the multiple second connecting holes 311 with their corresponding first connecting holes 111 facilitates the positioning of the support member 300 on the rear longitudinal beam 110, ensuring the accuracy of the support member 300's installation position.

[0060] Understandably, the fasteners, the first connecting hole 111 and the second connecting hole 311 facilitate the detachable connection of the support member 300 to the rear longitudinal beam 110.

[0061] Reference Figure 2 and Figure 3 In a specific implementation, there are multiple second connecting holes 311 spaced apart along the vehicle height direction. Any one of the multiple second connecting holes 311 is opposite to the first connecting hole 111 and connected by a fastener 400 to adjust the height of the support member 300.

[0062] Understandably, by providing multiple second connecting holes 311 spaced apart along the vehicle height direction, it is convenient to adjust the height of the support member 300, thereby adjusting the support height of the side plate 120, and thus adjusting the height of the floor assembly 100.

[0063] Reference Figure 2 and Figure 3In some embodiments, the support portion 320 is formed as a support plate parallel to the side plate 120. This parallel configuration ensures sufficient contact area and support effectiveness between the support portion 320 and the side plate 120. The support plate extends along the left-right direction of the vehicle and is spaced apart from the side panel assembly 200. This spacing helps reduce the weight of the portion of the side plate 120 near the side panel assembly 200 or the downward load along the vehicle height direction, further preventing the side plate 120 from slipping. The side plate 120 is supported by the rear longitudinal beam 110 and the support plate, and the side plate 120 is welded to the support plate. This welding of the side plate 120 to the support plate prevents noise caused by vibration.

[0064] Reference Figure 2 and Figure 5 In some embodiments, the side plate 120 is provided with a vertically extending connecting flange 121, which is attached to and welded to the side panel assembly 200. It is understood that by providing the flange 121, the contact area between the side plate 120 and the side panel assembly 200 is increased, and with welding, the connection strength between the flange 121 and the side panel assembly 200 is enhanced.

[0065] In specific implementation, the width of the welding area connecting the flange 121 and the side assembly 200 is less than or equal to 16mm to avoid deformation of this area due to welding. For example, the width of this welding area can be between 8mm and 16mm, such as 8mm, 10mm, 12mm, 14mm, or 16mm. A width greater than or equal to 8mm helps ensure connection strength, while a width less than or equal to 16mm helps reduce welding difficulty and avoid deformation during welding. Understandably, the width of this welding area can also be less than 8mm; a width less than 8mm enhances the structural appearance.

[0066] Reference Figure 4 and Figure 5 The body structure 1000 also includes a sealant 500, which is applied to the mating gap between the connecting flange 121 and the side assembly 200 to seal the gap. It should be noted that welding does not completely waterproof the body. The sealant 500 helps to waterproof the body, preventing water from entering the interior of the body structure. For example, the width of the sealant 500 ranges from 5mm to 9mm.

[0067] Reference Figure 1 Furthermore, embodiments of this application also provide a vehicle including the aforementioned body structure 1000. Misalignment is less likely to occur between the vehicle's floor assembly 100 and side panel assembly.

[0068] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
