[0026] Please also read Figures 1 to 5 The floor structure and vehicle provided by the utility model are now described. The floor structure includes a first plate body 1, a light interlayer 2, a second plate body 3 and a pipeline 4. The light interlayer 2 is stacked on the first plate body 1, and the second plate body 3 is stacked on the light interlayer 2. The light interlayer 2 is provided with an installation groove 21, and the pipeline 4 is embedded in the installation groove 21.

[0027] Compared with the prior art, the floor structure provided in the present embodiment is a floor structure in which a first plate body 1, a lightweight interlayer 2 and a second plate body 3 are stacked in sequence to form a sandwich-like interlayer structure. An installation groove 21 is provided on the middle lightweight interlayer 2 to embed components such as pipelines 4, so that the pipelines 4 are stably confined in the lightweight interlayer 2, thereby achieving effective pressing of the pipelines 4 and the lightweight interlayer 2, simplifying the assembly process of the pipelines 4, reducing the occupied space in the vehicle, improving the space utilization rate of the entire vehicle, and at the same time reducing the weight of the vehicle body and reducing the energy consumption of the vehicle.

[0028] In this embodiment, the first plate body 1, the light interlayer 2, and the second plate body 3 are stacked from bottom to top, and the installation of the pipeline 4 is achieved by providing a mounting groove 21 on the light interlayer 2. The mounting groove 21 can be provided on the top surface of the light interlayer 2, with an opening facing upward, or can be provided on the bottom surface of the light interlayer 2, with an opening facing downward. The mounting groove 21 can not only install and accommodate the pipeline 4, but also limit the pipeline 4 through the two side walls of the groove body to prevent the pipeline 4 from falling out.

[0029] Taking the installation groove 21 set on the top surface of the lightweight interlayer 2 as an example, when the pipeline 4 is installed in the installation groove 21, the second plate body 3 above forms a covering effect on the upper opening of the installation groove 21, preventing the pipeline 4 from escaping from the upper opening of the installation groove 21, thereby ensuring the reliability of the installation of the pipeline 4.

[0030] The pipeline 4 mainly includes tubular components such as brake pipelines or cooling pipes, and also includes wire components such as high-voltage wires. The installation groove 21 is set accordingly according to the different sizes of the pipeline 4, which must not only meet the installation requirements of the pipeline 4, but also form a limiting effect on the pipeline 4 to prevent the pipeline 4 from falling out.

[0031] In some possible implementations, the above-mentioned characteristic lightweight interlayer 2 is adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The pipeline 4 includes a cooling pipeline 41, and the cooling pipeline 41 includes a water supply pipe 411 and a water return pipe 412. The water supply pipe 411 extends from front to back to be connected to the heat exchange component, and the water return pipe 412 is connected to the heat exchange component and bends and extends from back to front.

[0032] In this embodiment, the cooling pipeline 41 includes a water supply pipe 411 and a water return pipe 412. The water supply pipe 411 is used to supply cooling water to the heat exchange component, and the return pipe 412 is used to discharge the water that has completed heat exchange in the heat exchange component and has a certain temperature. The heat exchange component is used to cool the components to be cooled at the rear of the vehicle body, thereby ensuring a good cooling and heat exchange effect.

[0033] At the same time, the water supply pipe 411 adopts a straight pipe extending from front to back, which facilitates the smooth delivery of low-temperature cooling water into the heat exchange component, and the return pipe 412 bends forward to form an approximately S-shaped structure, which can increase the coverage area on the lightweight interlayer 2, and facilitate the use of high-temperature return water to heat the floor of the vehicle, which has a certain heating effect and can fully utilize the heat. Especially in the cold winter, the vehicle can be preheated and heated, which is convenient for reducing the energy consumption of the vehicle.

[0034] In some possible implementations, the first plate body 1, the light interlayer 2 and the second plate body 3 are as follows: Figures 1 to 4 See the structure shown. Figures 1 to 4 The front parts of the first plate body 1, the lightweight interlayer 2 and the second plate body 3 are gradually bent forward and upward, the rear ends of the water supply pipe 411 and the return pipe 412 are respectively connected to the heat exchange components, and the front ends of the water supply pipe 411 and the return pipe 412 are respectively set through the first plate body 1.

[0035] In this embodiment, in order to adapt to the changing trend of the vehicle body, the first plate body 1, the lightweight interlayer 2 and the front part of the second plate body 3 form a structure that bends and extends upward at the same time. In order to simplify the installation and layout of the water supply pipe 411 and the return pipe 412, the front part of the water supply pipe 411 and the return pipe 412 directly penetrates the first plate body 1 forward and extends to the front side of the first plate body 1.

[0036] It should be noted that, since the lightweight interlayer 2 is bent upward synchronously with the first plate body 1, the depth of the installation groove 21 is set according to the bending amplitude to ensure that the front of the water supply pipe 411 and the water return pipe 412 meet the trend of horizontally extending forward. If the bending amplitude of the lightweight interlayer 2 is too large, it is difficult to meet the extension direction requirements of the water supply pipe 411 and the water return pipe 412 by changing the depth of the installation groove 21, then the front of the water supply pipe 411 and the water return pipe 412 penetrates the bottom wall of the lightweight interlayer 2.

[0037] In some possible implementations, the first plate 1 of the above-mentioned feature is adopted as follows Figures 4 to 5 See the structure shown. Figures 4 to 5 A joint seat 5 is respectively provided on the front and rear sides of the first plate body 1, and each joint seat 5 has a first joint pipe 51 and a second joint pipe 52 extending along the front and rear directions. The first joint pipe 51 is connected to the end of the water supply pipe 411, and the second joint pipe 52 is connected to the end of the return pipe 412.

[0038] In this embodiment, the setting of the joint seat 5 facilitates the installation and fixation of the water supply pipe 411 and the return pipe 412. At the same time, the setting of the first joint pipe 51 and the second joint pipe 52 on the joint seat 5 realizes the connection with the water supply pipe 411 and the return pipe 412 respectively, which is convenient for realizing effective connection with the external pipeline through the first joint pipe 51 and the second joint pipe 52, thereby improving the convenience of installation and helping to improve the connection efficiency.

[0039] In some embodiments, the first plate 1 with the above characteristics can be used as follows Figure 4 See the structure shown. Figure 4 A reinforcing plate 11 extending downward is connected to the front lower part of the first plate body 1, and connecting parts 12 bent backward and connected to the bottom surface of the first plate body 1 are provided on both sides of the reinforcing plate 11. The joint seat 5 is connected to the front side of the reinforcing plate 11, and the first joint pipe 51 and the second joint pipe 52 are respectively arranged to penetrate the reinforcing plate 11 backward.

[0040] In this embodiment, the installation of the connector base 5 is facilitated by providing a reinforcing plate 11 on the front side of the first plate body 1. The reinforcing plate 11 extends downward, and the connector base 5 is installed on the front side of the reinforcing plate 11 and connected to the reinforcing plate 11 through a connector.

[0041] The joint seat 5 is a plate-shaped component attached to the front side of the reinforcing plate 11. The main axes of the first joint tube 51 and the second joint tube 52 are respectively perpendicular to the plate surface of the joint seat 5 and penetrate the joint seat 5. The peripheral walls of the first joint tube 51 and the second joint tube 52 are fixedly connected to the joint seat 5 to form a stable overall structure.

[0042] On this basis, connecting parts 12 are respectively provided on both sides of the reinforcing plate 11 . The connecting parts 12 are perpendicular to the plate surface of the reinforcing plate 11 , which can effectively support the reinforcing plate 11 and ensure the reliability of the installation of the connector seat 5 .

[0043] In some possible implementations, the first plate 1 and the second plate 3 are configured as follows: Figures 1 to 5 See the structure shown. Figures 1 to 5 A first armrest boss 13 extending in the front-to-back direction is provided in the middle of the first plate body 1, a second armrest boss 31 covering the first armrest boss 13 is provided in the middle of the second plate body 3, two lightweight interlayers 2 are provided, and the two lightweight interlayers 2 are respectively located on both sides of the first armrest boss 13.

[0044] In this embodiment, corresponding to the position of the vehicle armrest box, a first armrest boss 13 is set on the first plate body 1, and a second armrest boss 31 is set on the second plate body 3, and two lightweight interlayers 2 are distributed on both sides of the first armrest boss 13 to achieve reasonable layout of the space.

[0045] For some possible implementations, see Figure 1 The pipeline 4 includes a cable 42, and the cable 42 extends in the front-to-back direction. When the cable 42 is installed, the front end of the cable 42 extends to the front side of the lightweight interlayer 2, and the rear end of the cable 42 extends to the rear side of the lightweight interlayer 2, so as to facilitate connection with an external cable.

[0046] In some embodiments, a plurality of cables 42 are provided, and a plurality of mounting grooves 21 are also provided, and correspond one to one with the cables 42. The number of cables 42 is arranged according to actual needs, and a plurality of cables 42 can be arranged in parallel, and a plurality of mounting grooves 21 corresponding one to one with the cables 42 need to be pre-opened on the lightweight interlayer 2, and the mounting grooves 21 are used to accommodate the cables 42, so as to realize a reasonable arrangement of the cables 42.

[0047] Specifically, the front ends of several installation slots 21 converge and are interconnected, and the rear ends of several installation slots 21 converge and are interconnected. The above structure facilitates several cables 42 to extend outward from the same position, which is convenient for subsequent wiring and wiring, and avoids excessive space occupation.

[0048] It should be noted that, for a vehicle that needs to install both the cooling pipe 41 and the cable 42, the cooling pipe 41 and the cable 42 can be installed on the two lightweight interlayers 2 in a one-to-one correspondence to avoid interference between the two components.

[0049] Based on the above structure, please refer to Figure 4 and Figure 5By setting a circumferential flange 14 on the outer peripheral edge of the first plate body 1, a cavity structure capable of accommodating the lightweight interlayer 2 and the first plate body 1 is formed above the first plate body 1. In order to enhance the limiting effect, upper flanges 32 are respectively set on the front and rear sides of the second plate body 3. The contact between the upper flange 32 and the front and rear inner walls of the circumferential flange 14 realizes reliable limiting of the front and rear directions of the second plate body 3, ensures the stability of the relative position of the second plate body 3 and the first plate body 1, and also facilitates the structural installation.

[0050] In this embodiment, a circumferential flange 14 is provided on the outer peripheral edge of the first plate body 1, so that a cavity structure capable of accommodating the lightweight interlayer 2 and the first plate body 1 is formed above the first plate body 1. In order to enhance the limiting effect, upper flanges 32 are provided on the front and rear sides of the second plate body 3, respectively, and the contact between the upper flange 32 and the front and rear inner walls of the circumferential flange 14 realizes reliable limiting of the front and rear directions of the second plate body 3, thereby ensuring the stability of the relative position of the second plate body 3 and the first plate body 1, and facilitating the structural installation.

[0051] In this embodiment, lower flanges 33 are also provided on the left and right sides of the second plate body 3. The effective limitation of the left and right directions of the second plate body 3 is achieved through the contact between the outer wall of the lower flange 33 and the left and right inner walls of the circumferential flange 14. At this time, the four edges of the front, back, left and right of the second plate body 3 are all limited.

[0052] On this basis, after the second plate body 3 is installed on top of the first plate body 1, the lower flange 33 is located on the outer periphery of the lightweight interlayer 2, and the lower edge of the lower flange 33 contacts the top surface of the first plate body 1, so that the upper and lower positions of the second plate body 3 and the first plate body 1 are also synchronously limited, which effectively simplifies the installation process and ensures assembly accuracy.

[0053] Based on the same inventive concept, the embodiment of the present application also provides a vehicle, which includes a floor structure. The floor structure of the above-mentioned vehicle stacks the first plate body 1, the light interlayer 2 and the second plate body 3 in sequence to form a sandwich-like sandwich structure, and sets a mounting groove 21 on the middle light interlayer 2 to embed components such as pipelines 4, so that the pipelines 4 are stably limited in the light interlayer 2, and the pipelines 4 are effectively pressed with the light interlayer 2, which simplifies the assembly process of the pipelines 4, reduces the occupation of the space inside the vehicle, improves the space utilization rate of the whole vehicle, and reduces the weight of the vehicle body and reduces the energy consumption of the vehicle.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
