[0019] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0020] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in their functionality. For example, the term "including" used throughout the specification and claims is an open-ended term and should be interpreted as meaning "including but not limited to." "Substantially" means that those skilled in the art can solve the technical problem within a certain error range and achieve a substantial technical effect.
[0021] The vehicle body support frame assembly, vehicle body structure assembly and vehicle proposed in this application will be further explained below with reference to specific implementation methods and accompanying drawings.
[0022] See also Figures 1 to 2 The embodiment of the present application provides a vehicle body support frame assembly 100, which is used to support the vehicle body 301 ( Figure 8 ), thereby supporting the vehicle 300 and various components mounted thereon. Specifically, the vehicle body 301 includes a roof 210, a left side panel 230, and a right side panel 250. The different structures of the vehicle body support frame assembly 100 respectively support the roof 210, the left side panel 230, and the right side panel 250, thereby supporting the vehicle body 301 in different directions.
[0023] In this embodiment, the vehicle body support frame assembly 100 includes a first support frame 10 and a second support frame 30. The first support frame 10 is adapted to connect between the left side panel 230 and the right side panel 250 to support the vehicle body 301 in a first direction X. The second support frame 30 is spaced apart from the first support frame 10 and adapted to connect between at least one of the left side panel 230 and the right side panel 250 and the roof 210 to support the vehicle body 301 in a second direction Y. The first direction X and the second direction Y intersect, and the angle between them can be greater than or equal to 45 degrees. As an example, the first direction X can be horizontal, and the second direction Y can be vertical. References herein to a component being able to "support the vehicle body in a first direction X" should be understood broadly. This does not necessarily mean that the component must have components extending strictly along the first direction X to support the vehicle body 301 in the first direction X. Rather, it should be understood that the component is able to provide a supporting force to the vehicle body 301, with the supporting force having a component in the first direction X, thereby enabling the component to withstand and distribute loads in the first direction X. Similarly, the description in this specification that a certain element can "support the vehicle body in the second direction Y" should be understood in a broad sense. It does not mean that the element must have a component that strictly extends along the second direction Y to support the vehicle body 301 in the second direction Y. It should be understood that: the element can provide a supporting force to the vehicle body 301, and the supporting force has a component in the second direction Y, so that the element can bear and disperse the load from the second direction Y.
[0024] The first support frame 10 and the second support frame 30 in the vehicle body support frame assembly 100 are capable of supporting the vehicle body in different directions. Both the first support frame 10 and the second support frame 30 can be connected between the left side panel 230 and the right side panel 250. This significantly improves the torsional and flexural rigidity of the vehicle body 301. While meeting the functional and performance requirements of the vehicle body 301, the vehicle body support frame assembly 100 has a simple structure, achieving a lightweight design, meeting production process requirements, and reducing manufacturing costs. Furthermore, when the vehicle body support frame assembly 100 is used in a vehicle 300, it is installed between the roof 210, the left side panel 230, and the right side panel 250. This allows for support of the vehicle body 301 in different directions, while simplifying the structure and reducing the weight of the vehicle 300.
[0025] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; internal communication between two components; or mere surface contact. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
[0026] Furthermore, 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 the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.
[0027] See also Figures 3 and 4 In this embodiment, the first support frame 10 includes a first support assembly 12, a second support assembly 14, and a connector 16. The first support assembly 12 and the second support assembly 14 are respectively connected to opposite sides of the connector 16 and arranged along a first direction X, wherein the angle between the first direction X and the horizontal direction is less than or equal to 15 degrees. For example, in this embodiment, the first direction X is arranged substantially parallel to the horizontal direction. Furthermore, the first support frame 10 is arranged along a first plane, wherein the angle between the first plane and the vertical direction is less than or equal to 20 degrees. For example, in this embodiment, the first support assembly 12 and the second support assembly 14 of the first support frame 10 jointly define the first plane, and the angle between the first plane and the vertical direction is 15 degrees. The first support frame 10 is suitable for limiting the load distribution in the first direction X and improving the dynamic stiffness of the rear portion of the vehicle body 301 in the first direction X.
[0028] In this embodiment, the first support assembly 12 is adapted to be connected to the left side panel 230 to support the left side panel 230 and components mounted thereon. Specifically, in this embodiment, the first support assembly 12 includes a first support rod 121 and a second support rod 123. The first support rod 121 and the second support rod 123 jointly support the left side panel 230 to enhance the support provided by the first support assembly 12 to the left side panel 230. The first support rod 121 includes a first connecting end 1211 and a first supporting end 1213, which are located at opposite ends of the first support rod 121. The first connecting end 1211 is connected to the connector 16, and the first supporting end 1213 is used to connect to the left side panel 230 to support it. The second support rod 123 includes a second connecting end 1231 and a second supporting end 1233. The second connecting end 1231 and the second supporting end 1233 are located at opposite ends of the second support rod 123. The second connecting end 1231 is connected to the connector 16 and is connected to the same side of the connector 16 as the first connecting end 1211. The second supporting end 1233 is used to connect to the left side panel 230 to support the left side panel 230. Furthermore, the angle between the first support rod 121 and the second support rod 123 is less than or equal to 45 degrees, so that the first supporting end 1213 and the second supporting end 1233 are spaced apart, thereby increasing the support strength of the first support assembly 12 on the left side panel 230. Furthermore, in this embodiment, the first supporting end 1213 and the second supporting end 1233 are spaced apart in the second direction Y. Among them, the angle between the second direction Y and the vertical direction is less than or equal to 15 degrees. For example, in this embodiment, the angle between the second direction Y and the vertical direction is 15 degrees, so that the first support end 1213 and the second support end 1233 can support the left side panel 230 in the second direction Y.
[0029] In some instances, the second direction Y may also be a vertical direction. It should be understood that the two elements described in this specification as "spaced apart in the second direction Y" should be broadly understood as the two elements being spaced apart in the second direction Y, rather than strictly limiting the two elements to being linearly arranged along the second direction Y. For example, the first support end 1213 and the second support end 1233 are "spaced apart in the second direction Y." A specific example of this is that the first support end 1213 and the second support end 1233 are linearly arranged along the second direction Y. For example, when projected along the second direction Y, the projections of the two have overlapping parts, so that Figure 3The orientation in the figure is used as a reference for description. The second support end 1233 can be located directly below the first support end 1213. Alternatively, the first support end 1213 and the second support end 1233 do not have to be arranged linearly along the second direction Y, but are staggered in the second direction Y, and the two are not arranged in the same horizontal plane. When projected along the second direction Y, the projections of the two have overlapping parts or there is a certain interval between the projections of the two. From a macroscopic perspective, Figure 3 The orientation in the figure is for description reference, and the second support end 1233 can be located at the lower left, lower right, etc. of the first support end 1213.
[0030] This specification does not limit the connection method between the first support end 1213, the second support end 1233, and the left side panel 230. The connection method between the first support end 1213, the second support end 1233, and the left side panel 230 can be adhesive bonding, screwing, riveting, or a combination of these. For example, in this embodiment, the first support end 1213, the second support end 1233, and the left side panel 230 are adhesively bonded in an overlapping manner using structural adhesive. In this embodiment, the first support rod 121 and the second support rod 123 are both hollow tubular and can be molded from a carbon fiber reinforced epoxy resin-based composite material. The thickness of the tubing is between 1.6 mm and 1.7 mm. For example, in this embodiment, the thickness of the tubing is 1.67 mm, meeting the lightweight, performance, and assembly accuracy requirements of the vehicle body support frame assembly 100.
[0031] In this embodiment, the second support assembly 14 is adapted to be connected to the right side panel 250 to support the right side panel 250 and components mounted thereon. Specifically, in this embodiment, the second support assembly 14 includes a third support rod 141 and a fourth support rod 143. The third support rod 141 and the fourth support rod 143 jointly support the right side panel 250, thereby enhancing the support provided by the second support assembly 14 to the right side panel 250. In this embodiment, the third support rod 141 and the second support rod 123 are arranged substantially along the same straight line, while the fourth support rod 143 and the first support rod 121 are arranged substantially along the same straight line. The third support rod 141, the fourth support rod 143, the first support rod 121, and the second support rod 123 collectively form a cross-X-shaped support structure, which facilitates enhancing the torsional rigidity of the first support frame 10.
[0032] The third support rod 141 includes a third connecting end 1411 and a third supporting end 1413. The third connecting end 1411 and the third supporting end 1413 are located at opposite ends of the third support rod 141. The third connecting end 1411 is connected to the connecting member 16. The third supporting end 1413 is used to connect to the right side panel 250 to support the right side panel 250. The fourth support rod 143 includes a fourth connecting end 1431 and a fourth supporting end 1433. The fourth connecting end 1431 and the fourth supporting end 1433 are located at opposite ends of the fourth support rod 143. The fourth connecting end 1431 is connected to the connecting member 16 and is connected to the same side of the connecting member 16 as the third connecting end 1411. The fourth supporting end 1433 is used to connect to the right side panel 250 to support the right side panel 250. Furthermore, the angle between the third support rod 141 and the fourth support rod 143 is less than or equal to 45 degrees, so that the third support end 1413 and the fourth support end 1433 are spaced apart, thereby increasing the support strength of the third support assembly 14 on the right side panel 250. Furthermore, in this embodiment, the third support end 1413 and the fourth support end 1433 are spaced apart in the second direction Y, so that the third support end 1413 and the fourth support end 1433 can support the right side panel 250 in the second direction Y.
[0033] This specification does not limit the connection method between the third support end 1413, the fourth support end 1433, and the right side panel 250. The connection method between the third support end 1413, the fourth support end 1433, and the right side panel 250 can be adhesive bonding, screwing, riveting, or a combination of these. For example, in this embodiment, the third support end 1413, the fourth support end 1433, and the right side panel 250 are adhesively bonded in an overlapping manner using structural adhesive. In this embodiment, the third support rod 141 and the fourth support rod 143 are molded from a carbon fiber reinforced epoxy resin-based composite material tube with a thickness between 1.6 mm and 1.7 mm. For example, in this embodiment, the tube thickness is 1.67 mm, to meet the lightweight, performance, and assembly accuracy requirements of the vehicle body support frame assembly 100.
[0034] In this embodiment, the connector 16 includes a first connecting plate 161 and a second connecting plate 163. The first connecting plate 161 and the second connecting plate 163 are interlocked to assemble to form the connector 16. This specification does not limit the connection method between the first support assembly 12, the second support assembly 14, and the connector 16. The connection method between the first support assembly 12, the second support assembly 14, and the connector 16 can be adhesive, screw, riveted, or a mixed design. Specifically, in this embodiment, the connector 16 is provided with connecting holes. The number of connecting holes can be four. The four connecting holes are arranged in pairs on opposite sides of the connector 16. The first connecting end 1211, the second connecting end 1231, the third connecting end 1411, and the fourth connecting end 1431 are respectively at least partially embedded in the connecting holes, so that the connection between the connector 16 and the first support assembly 12 and the second support assembly 14 is more stable. Furthermore, adhesive bonding and bolting are employed to connect the first connecting end 1211, the second connecting end 1231, the third connecting end 1411, and the fourth connecting end 1431 to the connecting holes, thereby enhancing the connection strength between the connecting member 16 and the first and second support assemblies 12, 14. In this embodiment, the connecting member 16 is constructed of high-pressure vacuum die-cast aluminum. The overlap length between the connecting member 16 and the first and second support assemblies 12, 14 is 30 mm, and the adhesive layer thickness is 1.5 mm, thereby meeting the lightweight, performance, and assembly precision requirements of the vehicle body support frame assembly 100.
[0035] See also Figure 5 In this embodiment, the second support frame 30 includes a first connecting rod 32 and a second connecting rod 34. The first connecting rod 32 is adapted to be connected between the left side panel 230 and the top cover 210, so that the first connecting rod 32 supports the vehicle body 301 in the second direction Y. The second connecting rod 34 is adapted to be connected between the right side panel 250 and the top cover 210, so that the second connecting rod 34 supports the vehicle body 301 in the second direction Y. Furthermore, the second support frame 30 is arranged along a second plane. For example, the first connecting rod 32 and the second connecting rod 34 jointly define the second plane. The angle between the second plane and the vertical direction is less than or equal to 15 degrees. For example, in this embodiment, the angle between the second plane and the vertical direction is 15 degrees.
[0036] One end of the first connecting rod 32 is connected to the left side panel 230, and the other end is connected to the approximate middle position of the top cover 210. Therefore, the first connecting rod 32 is not arranged in the vertical direction, but is inclined relative to the vertical direction. The end of the first connecting rod 32 away from the left side panel 230 extends toward the head of the vehicle body (it is relatively closer to the head gap of the vehicle body), that is, it extends in the direction away from the first support frame 30, so that the supporting force of the first connecting rod 32 on the top cover 210 and the supporting force on the left side panel 230 can have components in the first direction X and the second direction Y, and it can withstand both the load in the second direction Y and the load in the first direction X. One end of the second connecting rod 34 is connected to the right side panel 250, and the other end is connected to the approximately middle position of the roof 210. Therefore, the second connecting rod 34 is not arranged vertically, but is tilted relative to the vertical direction. Furthermore, the end of the second connecting rod 34 that is away from the right side panel 250 extends toward the head of the vehicle (relatively closer to the head gap of the vehicle), that is, away from the first support frame 30. This allows the supporting force exerted by the second connecting rod 34 on the roof 210 and the right side panel 250 to have components in both the first direction X and the second direction Y, allowing it to withstand loads in both the second direction Y and the first direction X. Therefore, the first support frame 10 is suitable for limiting the load distribution in the first direction X and the second direction Y, and is capable of transmitting the load in the second direction Y from the arm locking mounting beam of the rear vehicle 300 during flight conditions, as well as the load in the first direction X from the rear shock absorber of the chassis of the vehicle body 301 during land conditions. In this embodiment, the first connecting rod 32 and the second connecting rod 34 are both hollow tubes, and can both be made of carbon fiber reinforced epoxy resin-based composite material molded tubes. The thickness of the tube material is between 1.6 mm and 1.7 mm. For example, in this embodiment, the thickness of the tube material is 1.67 mm to meet the lightweight, performance and assembly accuracy requirements of the vehicle body support frame assembly 100.
[0037] In this embodiment, the second support frame 30 also includes a first joint 36. The first connecting rod 32 and the second connecting rod 34 are connected to the first joint 36 and connected to the top cover 210 through the first joint 36 to support the top cover 210. Specifically, in this embodiment, the first joint 36 includes a connecting portion 361 and a top plate 363. The connecting portion 361 is used to connect the first connecting rod 32 and the second connecting rod 34. The top plate 363 is connected to the connecting portion 361 and overlaps the top cover 210 to be fixedly connected to the top cover 210. This specification does not limit the connection method between the first connecting rod 32, the second connecting rod 34 and the connecting portion 361. The connection method between the first connecting rod 32, the second connecting rod 34 and the connecting portion 361 can be adhesive, screw, riveted, or a mixed design. Specifically, in this embodiment, the connecting portion 361 includes two connecting holes. The first connecting rod 32 and the second connecting rod 34 are each at least partially embedded in the connecting holes to make the connection between the connecting portion 361 and the first connecting rod 32 and the second connecting rod 34 more stable. Furthermore, the two connecting holes are spaced apart from each other, and the first connecting rod 32, the second connecting rod 34 and the connecting holes are bonded together using structural adhesive to improve the connection strength of the first connecting rod 32 and the second connecting rod 34. Furthermore, the first joint 36 is made of high-pressure vacuum die-cast aluminum, the overlap length between the connecting portion 361 and the first connecting rod 32 and the second connecting rod 34 is 30 mm, the adhesive layer thickness is 1.5 mm, and the angle between the first connecting rod 32 and the second connecting rod 34 is greater than or equal to 100 degrees and less than or equal to 150 degrees. For example, in this embodiment, the angle between the first connecting rod 32 and the second connecting rod 34 is equal to 120 degrees, thereby improving the support strength of the second support frame 30. In this embodiment, the top plate 363 can be formed by two flat plates that are interlocked, so that the thickness of the top plate 363 is greater than the thickness of the connecting portion 361, thereby improving the connection strength between the second support frame 30 and the top cover 210.
[0038] In this embodiment, the third support frame 30 further includes a third connecting rod 37, which is connected between the first connecting rod 32 and the second connecting rod 34. The third connecting rod 37 is arranged along the first direction X to support the left side panel 230 and the right side panel 250 in the first direction X. In this embodiment, the third connecting rod 37 is a hollow tube, which can be molded from a carbon fiber reinforced epoxy resin-based composite material. The tube material thickness is between 1.6 mm and 1.7 mm. For example, in this embodiment, the tube material thickness is 1.67 mm, to meet the lightweight, performance, and assembly accuracy requirements of the vehicle body support frame assembly 100.
[0039] In this embodiment, the second support frame 30 further includes a second joint 38 and a third joint 39. The second joint 38 is adapted to connect to the left side panel 230 and is connected between the first connecting rod 32 and the third connecting rod 37. The third joint 39 is adapted to connect to the right side panel 250 and is connected between the second connecting rod 34 and the third connecting rod 37. This specification does not limit the connection method between the first connecting rod 32, the second connecting rod 34, the third connecting rod 37, and the second joint 38 and the third joint 39. The connection method between the first connecting rod 32, the second connecting rod 34, the third connecting rod 37, and the second joint 38 and the third joint 39 can be adhesive bonding, screw bonding, riveting, or a combination thereof. Specifically, in this embodiment, the second joint 38 includes a first mounting portion 381 and two first mounting holes 383. The first mounting portion 381 is adapted to connect to the left side panel 230. The mounting holes 383 are connected to the first mounting portion 381 and to the first connecting rod 32 and the third connecting rod 37. The two first mounting holes 383 are spaced apart from each other. Structural adhesive is used to bond the first connecting rod 32, the third connecting rod 37, and the first mounting holes 383 to enhance the connection strength between the first connecting rod 32, the third connecting rod 37, and the first mounting holes 383. Furthermore, the second joint 38 is constructed of high-pressure vacuum die-cast aluminum. The overlap length between the first connecting rod 32, the third connecting rod 37, and the first mounting holes 383 is 30 mm, and the adhesive layer thickness is 1.5 mm. The angle between the first connecting rod 32 and the third connecting rod 37 is greater than or equal to 100 degrees and less than or equal to 150 degrees. For example, in this embodiment, the angle between the first connecting rod 32 and the third connecting rod 37 is 120 degrees, thereby enhancing the support strength of the second support frame 30. The third joint 39 includes a second mounting portion 391 and two second mounting holes 393. The second mounting portion 391 is adapted to connect to the left side panel 230. The mounting hole 383 is connected to the second mounting portion 391 and to the second connecting rod 34 and the third connecting rod 37. The two second mounting holes 393 are spaced apart from each other. Structural adhesive is used to bond the second connecting rod 34, the third connecting rod 37, and the second mounting holes 393 to enhance the connection strength between the second connecting rod 34, the third connecting rod 37, and the second mounting holes 393.
