[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Unless otherwise specified, the front-to-back direction in this application refers to the longitudinal direction of the inner panel of the vehicle body, i.e., the X direction; the left-to-right direction refers to the transverse direction of the inner panel of the vehicle body, i.e., the Y direction; and the up-down direction refers to the vertical direction of the inner panel of the vehicle body, i.e., the Z direction.

[0029] The following is for reference. Figures 1-4 The vehicle body inner panel according to an embodiment of the present invention is described. The vehicle body inner panel is integrally formed to reduce the number of parts, thereby reducing the weight of the vehicle body inner panel, and the side panel 3 is easy to connect with external structural members.

[0030] It should be noted that the inner panel of the vehicle body includes: a front panel 1, a bottom panel 2, and two side panels 3. In actual operation, the front panel 1 can be vertically connected to the front end of the bottom panel 2, and the two side panels 3 can be vertically connected to the left and right sides of the bottom panel 2. Thus, the connected front panel 1, bottom panel 2, and side panels 3 together define the inner cavity of the vehicle body. Furthermore, the front panel 1, bottom panel 2, and two side panels 3 are all approximately rectangular plates, making the overall inner cavity of the vehicle body an open cuboid shape. The entire inner panel is a one-piece structure made of SMC composite material, which can be integrally molded, thereby reducing the number of parts and molds, simplifying the manufacturing process, reducing equipment processing costs, meeting vehicle integration requirements, and thus greatly reducing the weight of the inner panel, achieving lightweighting.

[0031] Furthermore, the side plate portion 3 includes an upper plate region 31 and a lower plate region 32 distributed along the vertical direction, with the plane of the upper plate region 31 located outside the plane of the lower plate region 32. That is, the upper plate region 31 and the lower plate region 32 are spaced apart along the Y direction, with the upper plate region 31 protruding away from the bottom plate portion 2 relative to the lower plate region 32. Simultaneously, the lower end of the upper plate region 31 and the upper end of the lower plate region 32 are connected by an intermediate plate region 33. A connecting portion protruding from the bottom of the intermediate plate region 33 is used for connection with external structural components.

[0032] Therefore, the staggered upper plate area 31 and lower plate area 32 can enhance the overall structural strength of the side plate section 3. At the same time, the connecting part protruding from the bottom of the middle plate area 33 can provide mounting points for the connecting parts in the external structural components, thereby realizing the connection between the external structural components and the side plate section 3. That is, the design of the connecting part can meet the assembly needs of the external structural components, while also preventing the connecting parts from being exposed on the outside of the vehicle body.

[0033] The inner panel of the vehicle body can be made of lightweight SMC composite material, which can further reduce the weight of the inner panel, resulting in an overall weight reduction of 22KG. Furthermore, SMC composite material has advantages such as good thermal stability, UV resistance, corrosion resistance, rust prevention, impact resistance, and structural strength, which can further improve the service life of the inner panel in this embodiment of the invention and enhance its applicability.

[0034] According to an embodiment of the present invention, the inner panel of the vehicle body integrates the front panel portion 1, the bottom panel portion 2, and the side panel portion 3 into a single structure, thereby reducing the number of parts and the weight of the inner panel. Furthermore, the side panel portion 3 can be bent along the Y-direction, which helps to strengthen the structural strength of the side panel portion 3. Simultaneously, a connecting portion is designed to provide mounting points to structural members on the outer side of the side panel portion 3, thereby achieving connection with the inner panel of the vehicle body.

[0035] In some embodiments, the connecting portion is configured as a first connecting flange 34 extending vertically downward. It should be noted that, as... Figure 3 As shown, the connecting portion extends downwards from the end near the upper plate region 31 in the intermediate plate region 33 to form a first connecting flange 34, such that the first connecting flange 34 is spaced apart from the lower plate region 32, that is, the first connecting flange 34 and the lower plate region 32 are spaced apart to define a downwardly open connecting space 35. The first connecting flange 34 has a first connecting hole 341 for a connector to pass through. The connector can be a screw, and the first connecting hole 341 is constructed as a threaded hole adapted to the screw thread, thereby ensuring a tight fit between the connector and the first connecting hole 341. Furthermore, the number of first connecting holes 341 is not unique; two, three, or other numbers can be provided, and this embodiment does not impose any limitation on this.

[0036] It is understandable that by setting a first connecting flange 34 and a first connecting hole 341 on the first connecting flange 34, the first connecting hole 341 is constructed as a rivet nut structure, so that the connecting parts in the external structural parts pass through the first connecting hole 341 and are fixedly connected to the first connecting flange 34, thereby realizing the connection between the side plate part 3 and the external structural parts.

[0037] The connecting space 35 provides assembly space for the remaining portion of the connector passing through the first connecting hole 341, thereby achieving the purpose of concealing the connector and preventing it from being exposed and affecting the visual effect. It also prevents the connector from touching other structural components. Furthermore, snap-fit ​​holes can be provided on the first connecting flange 34 according to actual needs, facilitating the provision of installation points for other structural components. It should be noted that this embodiment does not impose any limitations on the number or size of the snap-fit ​​holes.

[0038] In some embodiments, the outer surface of the first connecting flange 34 is configured as a connecting plane, which is used to fit and connect with a bracket or snap fastener for mounting external structural components. That is, in this embodiment, as Figure 3 As shown, the first connecting flange 34 is constructed as a strip extending along the Z direction, and the side of the first connecting flange 34 facing away from the lower plate region 32 is a connecting plane. Specifically, the connecting plane is constructed as a smooth strip-shaped plane, and two first connecting holes 341 are provided on the connecting plane, so that the remaining part of the connector after passing through the first connecting holes 341 can achieve surface contact with the connecting plane, ensuring the installation stability of the connector. If the connector is constructed as a bolt, after the bolt shank passes through the first connecting hole 341, the bolt head abuts against the connecting plane to achieve surface contact, thereby playing a limiting and fixing role.

[0039] It should be noted that, in this embodiment, the structure for installing the external structural component is a mounting bracket 200, such that one end of the mounting bracket 200 is provided with a second connecting flange 201, the second connecting flange 201 can be fitted and connected with the first connecting flange 34, and the second connecting flange 201 is provided with a first mating hole, and the first mating hole can be directly opposite to the first connecting hole 341.

[0040] Therefore, when the first connecting flange 34 and the second connecting flange 201 are fitted together, the connector passes through the first mating hole and the first connecting hole 341 in sequence, and finally extends to the connecting space 35 to tighten it, thereby completing the installation bracket 200 to be fixed on the connecting plane of the first connecting flange 34, connecting the external structural component to the other end of the buckle or bracket, thereby achieving the effect of fixing the external structural component to the side plate 3.

[0041] In some embodiments, there are multiple intermediate plate regions 33, which are sequentially distributed along the length of the side plate portion 3, and adjacent intermediate plate regions 33 have different heights. That is, as shown in the figure... Figure 2 As shown, multiple intermediate plate regions 33 are provided, and these multiple intermediate plate regions 33 are connected sequentially along the length direction of the side plate portion 3, thus penetrating the entire side plate portion 3. The heights of any two adjacent intermediate plate regions 33 are not the same, resulting in a zigzag pattern formed by the connection of multiple intermediate plate regions 33. This improves the bending moment of inertia of the side plate portion 3, increases structural strength, and prevents deformation of the side plate portion 3.

[0042] In some embodiments, the intermediate plate region 33 includes a plurality of first intermediate plate regions 331 and a plurality of second intermediate plate regions 332. The plurality of first intermediate plate regions 331 have the same height, the plurality of second intermediate plate regions 332 have the same height, and the plurality of first intermediate plate regions 331 and the plurality of second intermediate plate regions 332 are staggered along the length direction of the side plate portion 3. That is, as... Figure 2 As shown, both the first intermediate plate region 331 and the second intermediate plate region 332 are constructed as strip plates, and the heights of the first intermediate plate region 331 and the second intermediate plate region 332 are different, which can make the height of the first intermediate plate region 331 on the side plate portion 3 greater than the height of the second intermediate plate region 332 on the side plate portion 3 or the height of the first intermediate plate region 331 on the side plate portion 3 less than the height of the second intermediate plate region 332 on the side plate portion 3.

[0043] Understandably, in actual installation, the first intermediate plate area 331 and the second intermediate plate area 332 are staggered to form an alternating concave and convex intermediate plate area 33, thereby forming a structure similar to a reinforcing rib, which makes the side plate part 3 have good bending resistance, thereby increasing the structural strength of the side plate part 3.

[0044] In some embodiments, the upper end of the side panel portion 3 is provided with an outwardly extending reinforcing flange 36, which is used to connect with the outer panel of the vehicle body, and the reinforcing flange 36 is provided with a second connecting hole 3611 for a connector to pass through. It should be noted that, as... Figure 2 As shown, the reinforcing flange 36 is constructed as an L-shaped plate, and the reinforcing flange 36 can improve the structural strength of the side plate portion 3. Specifically, the reinforcing flange 36 includes a first sub-plate 361 and a second sub-plate 362. One end of the first sub-plate 361 is vertically connected to the upper end of the side plate portion 3, and the second sub-plate 362 is obliquely connected to the other end of the first sub-plate 361, so that the second sub-plate 362 can be disposed obliquely downward relative to the first sub-plate 361.

[0045] The first sub-plate 361 has a second connecting hole 3611, which can be configured as a rivet nut structure, allowing the rivet nut structure to be screwed and fixed to the connecting parts. It is understood that using screwing for fixing, compared to welding, can effectively simplify welding equipment and tooling, reduce processing costs, and improve processing efficiency. In actual installation, multiple second connecting holes 3611 can be provided, thereby further improving the connection stability of the outer panel of the carriage through the cooperation of multiple connecting parts with the second connecting holes 3611.

[0046] In some embodiments, the bottom plate portion 2 and / or the front plate portion 1 have a corrugated cross-section. That is, as... Figure 1 As shown, both the bottom plate and the front plate 1 have multiple corrugations forming a corrugated bottom plate 2 or front plate 1 facing the interior cavity of the vehicle body. The corrugations in the bottom plate 2 and the front plate 1 are the same size and spaced apart, and the corrugations in the bottom plate and the front plate 1 are horizontal in the X-direction. It is understood that constructing the bottom plate 2 and front plate 1 as corrugated allows for the use of the arched structure formed by the corrugations to enhance their respective load-bearing capacity, while also improving their impact resistance and vibration damping performance.

[0047] Furthermore, a first reinforcing sub-plate 37 is provided on the outer side of the side plate portion 3. That is to say, as... Figure 2 As shown, multiple spaced-apart first reinforcing sub-plates 37 are provided on the side of the side panel 3 facing away from the inner panel of the vehicle body. The reinforcing sub-plates extend downward from the top of the side panel 3 to a distance below the middle panel area 33. It should be noted that the first reinforcing sub-plates 37 in the two side panel sections 3 of the inner panel of the vehicle body can be symmetrically distributed along the X-direction, thereby ensuring that the side panel sections 3 on both sides can be subjected to uniform stress and consistent structural strength. Furthermore, by providing multiple first reinforcing sub-plates 37, the structural strength and stability of the side panel section 3 can be significantly improved.

[0048] Further, a second reinforcing sub-plate 21 is provided on a side of the bottom plate portion 2 facing away from the inner cavity of the cargo box, the number of the second reinforcing sub-plates 21 is plural, and the plurality of second reinforcing sub-plates 21 are arranged at intervals along the Y direction and evenly distributed on the bottom surface of the bottom plate portion 2, so as to improve the rigidity and strength of the bottom plate portion 2, thereby improving the load capacity.

[0049] In some embodiments, the bottom plate portion 2 is provided with a connecting boss 22, the connecting boss 22 is configured to be connected to a frame suspension, and a plurality of reinforcing ribs 221 are provided on an outer peripheral wall of the connecting boss 22. It should be noted that, as Figure 4 is shown, the bottom plate portion 2 protrudes downward to form a circular connecting boss 22, and the connecting boss 22 is a hollow structure, so that the connecting boss 22 can be connected to the frame suspension.

[0050] That is to say, in actual installation, a plurality of connecting bosses 22 can be provided on the bottom plate portion 2, and a plurality of reinforcing ribs 221 are provided on the outer peripheral wall of the connecting bosses 22, such that the plurality of reinforcing ribs 221 and the connecting bosses 22 together form a "meter"-shaped structure, wherein one reinforcing rib 221 of each of the two connecting bosses 22 located on the front side of the bottom plate portion 2 can extend along a diagonal of the bottom plate portion 2, which is beneficial to the stress stability of the reinforcing ribs 221 of the bottom plate portion 2. It can be understood that the arrangement of the plurality of reinforcing ribs 221 can improve the structural strength of the connecting boss 22 to meet the requirements of the whole vehicle.

[0051] In some embodiments, a reinforcing plate 11 is provided on the front side of the front plate portion 1, the reinforcing plate 11 is detachably connected to the front plate portion 1, and the reinforcing plate 11 extends along the length direction of the front plate portion 1. It should be noted that, as Figure 4 is shown, a folding plate 12 that folds outward and then downward is provided at the top end of the front plate portion 1, and the reinforcing plate 11 is provided at the top end of the front plate portion 1 and on a side close to the folding plate 12, such that the reinforcing plate 11 and the folding plate 12 are arranged at intervals.

[0052] Specifically, the reinforcing plate 11 is configured as a strip-shaped plate, and is detachably connected to the front plate portion 1 along the Y direction by bolts. That is to say, the reinforcing plate 11 can be fixed to the top end of the front plate portion 1 by means of bonding and bolt connection, so that the structural strength of the folding plate 12 can be improved, and the detachable connection is also beneficial to the installation and fixation of the front plate portion 1 and the reinforcing plate 11.

[0053] In some embodiments, a plurality of installation points are further provided on the inner plate of the cargo box to facilitate the installation of structures in the vehicle, as Figure 2 is shown, a power socket area A and a cargo box light installation area B are provided on the side plate portion 3, and a common rope hook through hole C and a folding rope hook installation hole D are also provided. Wherein, the cargo box light installation area is configured as a U-shaped groove, such that the cargo box light can extend into the groove for installation, thereby facilitating protection of the cargo box light.

[0054] In addition, multiple mounting point holes E are provided on the reinforcing ribs 221 on the left and right sides of the bottom plate 2, which can be used to provide mounting holes for the carbon canister pipe bracket, the refueling pipe bracket and the wiring harness clip, thereby satisfying the connection between the above structure and the inner panel of the vehicle body.

[0055] The present invention also proposes a vehicle.

[0056] According to an embodiment of the present invention, a vehicle body inner panel is provided with any of the above-described features. The front panel 1, side panel 3, and bottom panel 2 are made of SMC material, and these components are integrated into a single structure, thereby reducing the overall weight of the inner panel and achieving a lightweight design. The reinforcing sub-plates constructed in the side panel 3 and bottom panel 2, the reinforcing plate 11 provided at the top of the front panel 1, the reinforcing flange 36 constructed at the top of the side panel 3, and the corrugated structure of the bottom panel 2 and front panel 1, all work together to significantly improve the overall structural strength and rigidity of the inner panel, thus meeting the requirements of the vehicle.
