[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] Embodiment 1

[0045] The present embodiment relates to a vehicle body shelf structure, which can increase the overall structural strength of the shelf and help improve the quality of the entire vehicle.

[0046] In terms of overall structure, Figures 1 to 3 As shown, the vehicle body shelf structure of this embodiment mainly includes a shelf panel 1 and a shelf reinforcement 2 connected to the shelf panel 1 .

[0047] The shelf panel 1 includes an upper panel 101 arranged along the left-right direction of the vehicle, and a front panel 102 located in front of the upper panel 101. The front panel 102 is arranged along the up-down direction of the vehicle, and the top of the front panel 102 is connected to the upper panel 101. The shelf reinforcement 2 includes an upper reinforcement 21 arranged corresponding to the upper panel 101, and a front reinforcement 22 arranged corresponding to the front panel 102, and the upper panel 101 is connected to the upper reinforcement 21, and the front panel 102 is connected to the front reinforcement 22.

[0048] At this time, as set above, through the shelf board panel 1 and the shelf board reinforcement 2, this embodiment can use the shelf board reinforcement 2 to increase the overall structural strength of the shelf board, and can also use the shelf board panel 1 to ensure the overall appearance quality of the shelf board, thereby achieving the effect of improving the quality of the entire vehicle.

[0049] Based on the above overall introduction, in detail, Figure 1 As shown, the shelf panel 1 of this embodiment comprises an upper panel 101 and a front panel 102, wherein the upper panel 101 is arranged along the left-right direction of the vehicle, the front panel 102 is located in front of the upper panel 101, and the top of the front panel 102 is welded to the upper panel 101. Preferably, the shelf panel 1 of this embodiment is preferably integrally formed, which facilitates the preparation of the shelf panel 1.

[0050] Continue to view Figure 2 and Figure 3 In this embodiment, the shelf reinforcement 2 is connected to the shelf panel 1, and the shelf reinforcement 2 includes an upper reinforcement 21 and a front reinforcement 22. The upper reinforcement 21 is arranged corresponding to the upper panel 101 and connected to the upper panel 101. The front reinforcement 22 is arranged corresponding to the front panel 102 and connected to the front panel 102. In specific implementation, the left and right ends of the upper reinforcement are generally connected to the left and right side walls of the vehicle body, and the bottom of the front reinforcement 22 is generally connected to the rear floor of the vehicle body.

[0051] As a preferred embodiment, Figure 2 Combined with Fig. 9 and Fig.10 As shown, the upper reinforcement 21 of this embodiment specifically includes an annular outer frame, which has a front cross beam 211 and a rear cross beam 212 arranged front and rear, a left longitudinal beam 213 connected between the left ends of the front cross beam 211 and the rear cross beam 212, and a right longitudinal beam 214 connected between the right ends of the front cross beam 211 and the rear cross beam 212. The upper reinforcement 21 adopts an annular outer frame, which can utilize the high strength of the annular structure to ensure the structural strength of the upper reinforcement 21.

[0052] In order to increase the structural strength and support stiffness of the upper reinforcement 21, in this embodiment, Fig. 9 and Fig.10 As shown, a reinforcing longitudinal beam arranged along the front-to-rear direction of the vehicle is also connected between the front cross beam 211 and the rear cross beam 212. Specifically, the reinforcing beam includes a left reinforcing longitudinal beam 215 and a right reinforcing longitudinal beam 216 arranged at intervals in the left-right direction of the vehicle. It can be understood here that in addition to being set as two left and right reinforcing longitudinal beams, the reinforcing longitudinal beams can also be set as any number.

[0053] In this embodiment, as a preferred implementation, the front cross beam 211, the rear cross beam 212 and the reinforcing longitudinal beam are all surrounded by a cavity with the upper panel 101, and the cavities at the front cross beam 211 and the rear cross beam 212 are connected through the cavity at the reinforcing longitudinal beam. At this time, the cavity formed by the front cross beam 211, the rear cross beam 212 and the reinforcing longitudinal beam and the upper panel 101 can take advantage of the high strength of the cavity structure to better increase the overall strength of the upper part of the shelf.

[0054] Specific, combined Figures 3 to 5 As shown, a first cavity 10 is formed between the front cross beam 211 and the upper panel 101, a second cavity 20 is formed between the rear cross beam 212 and the upper panel 101, and a third cavity 30 and a fourth cavity 40 are formed between the reinforcing longitudinal beam and the upper panel 101, that is, between the left reinforcing longitudinal beam 215 and the right reinforcing longitudinal beam 216 and the upper panel 101, respectively. In addition, the first cavity 10 and the second cavity 20 are connected through the third cavity 30 and the fourth cavity 40. By setting the first cavity 10, the second cavity 20, the third cavity 30 and the fourth cavity 40, the overall strength of the upper part of the shelf can be better increased.

[0055] The front reinforcement 22 of this embodiment is as follows Figure 1 and Fig. 9 As shown, in terms of the overall structure, viewed from the left and right directions of the vehicle, the reinforcement is arranged to be tilted backwards, which helps to improve the transmission effect of the collision force.

[0056] As a preferred implementation, in this embodiment, the front reinforcement 22 includes a plurality of reinforcement brackets arranged at intervals along the left-right direction of the vehicle, and the front panel 102 includes a plurality of sub-panels arranged one-to-one corresponding to each reinforcement bracket, and each sub-panel is connected to the corresponding reinforcement bracket. In this case, the front reinforcement 22 uses a plurality of reinforcement brackets arranged at intervals, and the plurality of reinforcement brackets and the plurality of sub-panels are arranged one-to-one correspondingly, so that while achieving structural reinforcement, it is also convenient to achieve overall weight reduction of the shelf, which is conducive to lightweighting of the vehicle body.

[0057] In terms of specific structure, Figure 1 and Figure 4 As shown, the front panel 102 includes a left sub-panel 1021 and a right sub-panel 1022 arranged at intervals, and the plurality of reinforcing brackets include a left bracket 221 and a right bracket 222 arranged at intervals. The left sub-panel 1021 is connected to the left bracket 221, and the right sub-panel 1022 is connected to the right bracket 222.

[0058] Moreover, in order to increase the overall strength of the front part of the shelf, in this embodiment, each reinforcement bracket and the corresponding sub-panel form a cavity. In this way, the high strength of the cavity structure can be used to increase the overall strength of the front part of the shelf. Figure 3 , Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , a fifth cavity 50 is formed between the left bracket 221 and the left sub-panel 1021, and a sixth cavity 60 is formed between the right bracket 222 and the right sub-panel 1022.

[0059] From Figure 2 and in combination with Figure 4 and Fig. 9 As shown in Figure 4 and Fig. 9 , in this embodiment, as a preferred implementation manner, from the front-rear direction of the whole vehicle, each reinforcing bracket is in an "H" shape, and each reinforcing bracket includes an inner arm 2211 and an outer arm 2212 arranged relatively in the left-right direction of the whole vehicle, and a connecting arm 2213 connecting the inner arm 2211 and the outer arm 2212. At this time, the inner arm 2211, the outer arm 2212 and the connecting arm 2213 form an "H" shape structure, which has a simple structure, is also conducive to the preparation of the reinforcing bracket, and is also conducive to meeting the structural strength and support stiffness requirements of the front reinforcing member 22.

[0060] Moreover, as a further preferred implementation manner, in this embodiment, from the up-down direction of the whole vehicle, the outer arm 2212 of the left bracket 221 corresponds to the left longitudinal beam 213 in the front-rear direction, and the inner arm 2211 of the left bracket 221 corresponds to the left reinforcing longitudinal beam 215 in the front-rear direction, and the outer arm 2212 of the right bracket 222 corresponds to the right longitudinal beam 214 in the front-rear direction, and the inner arm 2211 of the right bracket 222 corresponds to the right reinforcing longitudinal beam 216 in the front-rear direction. With such a setting, on the basis that the upper reinforcing member 21 adopts a "mu" shape structure, in cooperation with each "H"-shaped reinforcing bracket, multiple coherent force transmission channels can be formed in the shelf reinforcing member 2, which is beneficial to improving the collision force transmission ability of the shelf reinforcing member 2.

[0061] Among them, multiple connected force transmission channels formed in the shelf reinforcing member 2 are as shown in Fig. 9 As shown in Fig. 9 , at this time, the double "H" shape structure composed of the front reinforcing member 22 corresponds to and penetrates through the "mu" shape structure of the upper reinforcing member 21, so that the shelf reinforcing member 2 forms an overall cage-like space structure, which can meet the force transmission requirements in all directions and can also improve the stiffness and NVH performance of the rear part of the vehicle body.

[0062] As a further improvement of this embodiment, in this embodiment, at least one of the shelf panel 1 and the shelf reinforcing member 2 is made of carbon fiber composite material. In this embodiment, both the shelf panel 1 and the shelf reinforcing member 2 are made of carbon fiber composite material. In this way, it is not only convenient for preparation, reduces the mold investment, shortens the development cycle, and reduces the preparation cost, but also can achieve the weight reduction of the shelf on the basis of ensuring the overall structural strength of the shelf, thus being beneficial to the lightweight design of the vehicle body.

[0063] In this embodiment, as shown in Figure 5As shown, the shelf reinforcement 2 is specifically connected to the shelf panel 1 by bonding through the structural adhesive 11. In specific implementation, the front cross beam 211, the rear cross beam 212, the left longitudinal beam 213, the right longitudinal beam 214, the left reinforced longitudinal beam 215, and the right reinforced longitudinal beam 216 are respectively bonded to the upper panel 101 by the structural adhesive 11. Moreover, the left bracket 221 and the right bracket 222 are also bonded to the corresponding left sub-panel 1021 and right sub-panel 1022 by the structural adhesive 11. This not only facilitates the assembly of the shelf reinforcement 2 and the shelf panel 1, but also ensures the connection strength between the shelf reinforcement 2 and the shelf panel 1.

[0064] In addition, it is worth mentioning that in the present embodiment, in addition to both the shelf board panel 1 and the shelf board reinforcement 2 being made of carbon fiber composite materials, it is also feasible to arrange only the shelf board panel 1 to be made of carbon fiber composite materials, or only the shelf board reinforcement 2 to be made of carbon fiber composite materials.

[0065] The vehicle body shelf structure of this embodiment can not only increase the overall structural strength of the shelf, but also ensure the overall appearance quality of the shelf, which is beneficial to improving the quality of the entire vehicle. At the same time, it can also effectively improve the force transmission efficiency of the shelf structure and the rigidity of the rear part of the vehicle body, and can also reduce mold investment and shorten the development cycle, thereby having a good use effect.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
