For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] The present embodiment relates to a vehicle cabin structure to overcome the problem in the prior art that the battery pack is arranged under the front floor 1 and occupies a large space, which is not conducive to the compactness and lightweight design of the vehicle body structure.

[0051] In terms of overall structure, the vehicle cabin structure includes an upwardly bulging middle channel 100 provided on the front floor 1. The bottom of the middle channel 100 forms a cavity 200 arranged along the front-to-back direction of the entire vehicle, and a front blocking structure is provided at the front end of the cavity 200, and a rear blocking structure is provided at the rear end of the cavity 200. The front blocking structure and the rear blocking structure define a battery pack arrangement space in the cavity 200.

[0052] The vehicle cabin structure described in this embodiment forms a cavity 200 arranged along the front-to-rear direction of the vehicle at the bottom of the central channel 100, and the front blocking structure and the rear blocking structure define a battery pack arrangement space in the cavity 200. The battery pack can be installed and arranged in the cavity 200 of the central channel 100. Compared with the traditional solution of arranging the battery pack under the front floor 1, the vehicle body space can be fully utilized, which is beneficial to increase the compactness of the vehicle body structure and is also beneficial to the lightweight design of the vehicle body.

[0053] Based on the above overall introduction, an exemplary structure of the vehicle cabin structure described in this embodiment is as follows: Figure 1 and Figure 2 As shown in . The front end of the front floor 1 is connected to the bottom of the front panel 2, and the rear end is connected to the bottom of the rear panel 3. The left and right sides of the front floor 1 are respectively connected to the threshold beams not shown in the figure. The middle channel 100 is located in the middle of the width direction of the front floor 1, and is extended along the front and rear direction of the vehicle, so that the front end of the middle channel 100 is connected to the front panel 2, and the rear end is connected to the rear panel 3, which is conducive to improving the connection and force transmission effect between the front floor 1 and the front panel 2 and the rear panel 3.

[0054] In this embodiment, since the middle channel 100 bulges upward, the bottom and both ends of the cavity 200 are open. The front blocking structure and the rear blocking structure are used to block the openings at the front and rear ends of the cavity 200 respectively, and the opening at the bottom of the cavity 200 constitutes an installation port for the battery pack to be placed in the battery pack layout space.

[0055] As a preferred embodiment, a reinforcement structure 4 is provided at the top of the middle channel 100, and the reinforcement structure 4 runs from the front end of the middle channel 100 to the rear end of the middle channel 100. By providing the reinforcement structure 4, the overall rigidity of the middle channel 100 can be increased, and the safety of the battery pack can be improved by increasing the rigidity of the middle channel 100. In addition, providing the reinforcement structure 4 at the top of the middle channel 100 can also reduce the impact on the battery pack layout space.

[0056] The front floor 1 in this embodiment is made of carbon fiber composite material, and includes a front floor upper plate 101 and a front floor lower plate 102 connected together. A cavity 300 located between the front floor upper plate 101 and the front floor lower plate 102 is formed at the top of the central channel 100, and the reinforcement structure 4 is formed by structural foam filled in the cavity 300. In this embodiment, the front floor 1 is made of carbon fiber composite material, which can take advantage of the high rigidity and light weight of carbon fiber composite material to ensure the rigidity of the vehicle body, improve the safety of the battery pack, and also help improve the lightweight level of the vehicle body.

[0057] like Figure 3 and Figure 5 As shown in the figure, the front floor lower plate 102 is provided with an inner protrusion 1021 that bulges upward and extends in the front-to-back direction of the vehicle. The front floor upper plate 101 is arranged in the shape of the front floor lower plate 102, and has an outer protrusion 1011 arranged in the shape of the inner protrusion 1021. The edges of the front floor upper plate 101 are provided with a first flange 1014 that is folded upward, and the edges of the front floor lower plate 102 are provided with a second flange 1024 that is folded upward. The first flange 1014 can be bonded and connected to the second flange 1024, so that the edges of the two are connected together. At the same time, the four sides of the front floor 1 are connected to the surrounding components through the second flange 1024.

[0058] In the connected state, the side wall of the outer protrusion 1011 abuts against the side wall of the inner protrusion 1021, and the top of the outer protrusion 1011 is spaced apart from the top of the inner protrusion 1021, and the above-mentioned cavity 300 is formed therebetween. In this embodiment, the front floor upper plate 101 and the front floor lower plate 102 cooperate to facilitate the arrangement of the reinforcement structure 4.

[0059] The reinforcement structure 4 in this embodiment is formed by structural foam, which has the advantages of easy layout and implementation, good reinforcement effect and light weight. Figure 7 and Figure 8 As shown in , the reinforcement structure 4 includes a reinforcement block 401 located at the rear end of the central channel 100, and reinforcement arms 402 respectively arranged at the left and right edges of the top of the central channel 100. Both reinforcement arms 402 extend from the front end of the central channel 100 to the rear end of the central channel 100, and are connected to the reinforcement block 401. The reinforcement structure 4 is composed of two reinforcement arms 402 arranged side by side and the reinforcement block 401 located at the rear end, which can ensure the connection strength with the rear panel 3 while making the central channel 100 have better structural strength, which helps to further improve the collision force transmission capacity of the central channel 100.

[0060] In the specific arrangement, the reinforcing block 401 and the two reinforcing arms 402 are connected to the top of the inner protrusion 1021, and the front end of each reinforcing arm 402 and the reinforcing block 401 are bonded and connected to the first flange 1014 to improve the connection strength of the reinforcing structure 4. Further, as Figure 7 and Figure 8 As shown in , an extension portion 4021 extending downward is provided on the outer side of the front end of each reinforcing arm 402, and the extension portion 4021 is bonded to the outer side of the inner protrusion 1021, which is beneficial to further improve the fixing effect of the reinforcing structure 4 on the top of the middle channel 100.

[0061] In order to improve the structural utilization of the middle channel 100, Figure 4 and Figure 6 As shown in , a recessed portion 1013 recessed downward is provided on the outer protrusion 1011 , and the recessed portion 1013 is located between the two reinforcing arms 402 . Such a configuration makes the shape of the cavity 300 match the shape of the reinforcing structure 4 .

[0062] In addition, in this embodiment, the width of the front end of the inner protrusion 1021 is gradually increased in the direction pointing to the front of the vehicle, so that the distance between the front ends of the two reinforcing arms 402 is gradually increased, and the front end of the outer protrusion 1011 is arranged in accordance with the inner protrusion 1021 and the two reinforcing arms 402. In this way, the front panel 2 can be prevented from intruding into the cabin during a collision, and the collision force at the front panel 2 can be transmitted to the central channel 100, which is conducive to improving the dispersion effect of the collision force.

[0063] like Figure 6 As shown in , the top of the rear end of the middle channel 100 is a slope 106 arranged obliquely toward the rear and upper part of the vehicle, and the top of the reinforcement block 401 is adapted to be inclined with the slope 106. That is, the top of the reinforcement block 401 is also inclined, and in the assembled state, the top surface of the reinforcement block 401 is arranged in contact with the slope 106. By providing the slope 106 at the rear end of the middle channel 100, the rear panel 3 can be prevented from intruding into the cabin during a collision, and the collision force at the rear panel 3 can be transmitted to the middle channel 100, which can improve the collision force dispersion effect.

[0064] To facilitate the installation of the battery pack on the front floor 1, in this embodiment, battery pack side mounting points are provided on the front floor 1 on the left and right sides of the cavity 200. The battery pack side mounting points on both sides include structural foam filled between the front floor upper plate 101 and the front floor lower plate 102, and mounting inserts embedded in the structural foam. The battery pack side mounting points are provided on the left and right sides of the cavity 200 here to ensure the reliability of the side of the battery pack being provided on the vehicle body. The provision of the structural foam and the mounting inserts therein facilitates the connection between the battery pack and the front floor 1, thereby helping to solve the problem that the battery pack mounting points cannot be directly formed on the carbon fiber composite material.

[0065] In order to distinguish it from the structural foam mentioned below, in this embodiment, the structural foam filled between the front floor upper plate 101 and the front floor lower plate 102 is called the first structural foam 103, and the installation insert embedded in the first structural foam 103 is the first installation insert 104. Figures 4 to 6 As shown in FIG, first protrusions 1022 protruding upward are respectively provided on both sides of the inner protrusion 1021, and the first protrusions 1022 are extended along the extension direction of the middle channel 100. Corresponding to each first protrusion 1022, second protrusions 1012 are respectively provided on both sides of the outer protrusion 1011.

[0066] like Fig. 9 and Fig.10 As shown in the figure, the first structural foam 103 is respectively filled in the space formed between the first protrusion 1022 and the second protrusion 1012 on the same side, and is bonded to the first protrusion 1022 or the second protrusion 1012. A plurality of first mounting inserts 104 are arranged at intervals along the extending direction of each first structural foam 103, and each first mounting insert 104 has a threaded hole formed therein. Corresponding to each first mounting insert 104, a plurality of first through holes 1023 are respectively provided on the top surface of the first protrusion 1022.

[0067] The two sides of the battery pack are respectively installed on the front floor 1 by bolts passing through the battery pack and the first through holes 1023 and screwing with the corresponding first mounting inserts 104. Here, the first structural foam 103 and the first mounting inserts 104 cooperate, which is convenient for layout and implementation, and has the advantages of good connection effect. At the same time, the two sides of the battery pack are detachably connected to the front floor 1, which also facilitates the installation and removal of the battery pack.

[0068] As a preferred embodiment, Figure 2 , Fig.11 and Fig.12 As shown in , the front blocking structure includes a blocking plate 5 connected to the inner wall of the cavity 200, and a groove 501 opening toward the front of the vehicle is formed on the upper part of the blocking plate 5, and a battery pack front mounting point is provided at the bottom of the blocking plate 5. Here, the groove 501 is provided on the blocking plate 5, so that the blocking plate 5 is box-shaped, and the high strength of the box-shaped structure is utilized to increase the structural strength of the blocking plate 5 itself, and the structure of the groove 501 is simple and easy to process and form. In addition, the battery pack front mounting point is provided at the bottom of the blocking plate 5, which can also ensure the reliability of the front part of the battery pack being installed on the vehicle body.

[0069] To further facilitate the lightweight design of the vehicle, the plugging plate 5 in this embodiment is made of carbon fiber composite material, and a closed inner cavity is formed at the bottom of the plugging plate 5. The front mounting point of the battery pack includes a structural foam filled in the closed inner cavity, and a mounting insert embedded in the structural foam. Among them, the plugging plate 5 is made of carbon fiber composite material, which can make the plugging plate 5 have a higher rigidity, which can ensure the rigidity of the front mounting point of the battery pack, and is also conducive to the weight reduction of the plugging plate 5. The arrangement of the structural foam and the mounting insert in the closed inner cavity of the plugging plate 5 is conducive to solving the problem that the battery pack mounting point cannot be directly formed on the carbon fiber composite material.

[0070] Hereinafter, the structural foam in the blocking plate 5 is referred to as the second structural foam 502, and the mounting insert disposed therein is referred to as the second mounting insert 503, and a threaded hole is also provided in the second mounting insert 503. As a feasible embodiment, the closed inner cavity at the bottom of the blocking plate 5 is extended along the width direction of the entire vehicle and is in the shape of a rectangular parallelepiped. The second structural foam 502 is filled in the closed inner cavity and is adapted to the shape of the closed inner cavity. The second mounting insert 503 is a plurality of second structural foams 502 spaced apart in the left-right direction of the entire vehicle, and a plurality of second through holes 504 are provided on the bottom wall of the blocking plate 5 corresponding to each second mounting insert 503. The front end of the battery pack is mounted on the front floor 1 by screwing bolts passing through the battery pack and the second through hole 504 and the corresponding second mounting insert 503.

[0071] like Figure 2 , Figures 13 to 15 As shown in , in this embodiment, the rear blocking structure includes a block 6 connected between the left and right side walls of the middle channel 100, and a baffle 301 located above the block 6, a battery pack rear mounting point is provided on the block 6, and the baffle 301 is composed of the rear panel 3. Here, the rear blocking structure is composed of the block 6 and the baffle 301 above, and the battery pack rear mounting point is provided on the block 6, and the baffle 301 adopts the rear panel 3 of the vehicle body, which can be conducive to simplifying the vehicle body structure and can also ensure the reliability of the rear part of the battery pack being set on the vehicle body.

[0072] For detailed structure, please refer to Figure 2 As shown in FIG. 1 , the stopper 6 is installed on the rear panel 3. To facilitate the installation of the stopper 6, a mounting groove 302 with an opening facing downward is provided at the bottom of the rear panel 3, and the stopper 6 is installed in the mounting groove 302. To improve the installation effect of the stopper 6 in the mounting groove 302, the groove opening of the mounting groove 302 is expanded outward, that is, the width of the mounting groove 302 is gradually increased from top to bottom.

[0073] Correspondingly, the two sides of the top of the stopper 6 are respectively provided with inclined guide surfaces, and due to the arrangement of the two guide surfaces, the cross section of the top of the stopper 6 is triangular. Here, the guide surfaces and the groove opening of the installation groove 302 are expanded outward, which facilitates the installation of the stopper 6 in the installation groove 302. In specific implementation, the stopper 6 can also be made of carbon fiber composite material, and the stopper 6 and the groove wall of the installation groove 302 are bonded and connected.

[0074] It is understandable that the shapes of the installation groove 302 and the stopper 6 can be adjusted according to the use requirements, as long as the installation requirements of the stopper 6 are met. In this embodiment, in addition to the stopper 6 being arranged on the rear panel 3, and the rear panel 3 forming the baffle 301, the stopper 6 and the baffle 301 can also be arranged separately. In this case, the baffle 301 cooperates with the stopper 6 to meet the requirements of blocking the rear end opening of the central channel 100.

[0075] As a preferred embodiment, the block 6 and the baffle 301 are both made of carbon fiber composite material, a closed cavity is formed inside the block 6, and the rear mounting point of the battery pack includes a structural foam filled in the closed cavity, and a mounting insert embedded in the structural foam. Here, the block 6 and the baffle 301 are made of carbon fiber composite material, which can ensure the rigidity of the block 6 and the baffle 301, and the rigidity of the rear mounting point of the battery pack, and also facilitate the weight reduction of the block 6 and the baffle 301, which helps to reduce the weight of the vehicle body.

[0076] In this embodiment, the structural foam in the stopper 6 is referred to as the third structural foam 601, and the mounting insert therein is referred to as the third mounting insert 602.
