[0001] This utility model belongs to the field of body-in-white processing, and specifically relates to an integrated body floor. Background Technology
[0002] The patent application, with publication number CN211765905U and subject name "An Integrated Semi-Trailer Two-Shelf Floor Plate," and IPC classification number B62D33 / 02, discloses a floor plate body and a cover plate pressed onto the floor plate body. The floor plate body includes a support plate and a fixing frame fixed around the support plate. The support plate has grooves evenly arranged along its length, each groove extending along the width of the support plate and having an inverted trapezoidal structure with a narrow bottom and a wide opening. The cover plate is locked and fixed to the support plate by a locking structure. The locking structure includes fixing holes on the side of the cover plate and positioning holes on the support plate corresponding to the fixing holes. Locking bolts are inserted into the corresponding fixing holes and positioning holes, and locking nuts are fitted on the locking bolts to achieve the connection and fixation of the cover plate and the support plate.
[0003] Therefore, the above utility model patents have disclosed one technical solution for an integrated semi-trailer two-tier floor plate. However, the technical solutions disclosed in these utility model patents focus on achieving uniform stress distribution on the cover plate, reducing friction between the cover plate and the support plate, and lowering the damage rate of the cover plate and support plate. They do not further address issues such as optimizing the distribution of vehicle load forces and require further improvement. Utility Model Content
[0004] This utility model addresses the shortcomings of the existing technology by providing an integrated vehicle chassis.
[0005] This utility model adopts the following technical solution: an integrated vehicle chassis floor, comprising a chassis body, multiple wheel arch accommodating structures, and multiple connecting strips, wherein:
[0006] Each wheel arch housing structure includes two wheel arches symmetrically distributed relative to the base plate body, and the two wheel arches are integrally formed with the base plate body;
[0007] Each connecting strip is integrally formed with the base plate body. The connecting strips are distributed along the width direction of the base plate body and the length of the connecting strips is longer than the width of the base plate body. There is a strip-shaped cavity between the connecting strips and the base plate body. At least one connecting strip is provided between two adjacent wheel arch receiving structures.
[0008] As a preferred technical solution to the above technical solutions, the vertical height of the wheel arch body relative to the base plate body is higher than the vertical height of the connecting strip relative to the base plate body.
[0009] As a preferred technical solution of the above technical solutions, the wheel arch body is provided with a wheel arch main body and a wheel arch bending part integrally formed with the wheel arch main body, and the wheel arch main body and the wheel arch bending part together form an open wheel arch cavity.
[0010] As a preferred technical solution of the above technical solution, the connecting strip is provided with a main body section and two extension sections. The two extension sections are respectively located at the two ends of the main body section and are integrally formed with the two ends of the main body section.
[0011] As a preferred technical solution to the above technical solutions, the main body of the connecting strip is directly opposite the base plate body, and the extension of the connecting strip extends out from the base plate body.
[0012] The integrated vehicle floor disclosed in this utility model has the advantage of optimizing the stress distribution of vehicle load based on its integrated design. The wheel arch accommodating structure and connecting strip share part of the load of the vehicle cabin and built-in equipment before transferring it to the floor body, thus avoiding the entire load acting directly on the floor body, thereby improving the overall structural strength and durability.

Detailed Implementation
[0022] This utility model discloses an integrated vehicle chassis plate. The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.
[0023] See attached diagram. Figures 1 to 8 , Figures 1 to 4 The integrated vehicle body floor is shown from different perspectives. Figures 5 to 8 The partial structure of the integrated vehicle body floor is shown from different perspectives.
[0024] Example 1.
[0025] Preferably, the integrated vehicle chassis floor includes a chassis body 100, multiple wheel arch accommodating structures 200 (preferably four wheel arch accommodating structures 200, the number of wheel arch accommodating structures 200 being consistent with the number of axles of the vehicle), and multiple connecting strips 300 (preferably seventeen connecting strips 300), wherein:
[0026] Each wheel arch housing structure 200 includes two wheel arch bodies 210 symmetrically distributed relative to the base plate body 100 (note that the wheel arch body 210 is not the wheel hub itself of the vehicle, but one of the structures used to house the wheel hub), and the two wheel arch bodies 210 are integrally formed with the base plate body 100 respectively;
[0027] Each connecting strip 300 is integrally formed with the base plate body 100. The connecting strips 300 are distributed along the width direction of the base plate body 100 and the length of the connecting strips 300 is longer than the width of the base plate body 100. There is a strip cavity 301 between the connecting strips 300 and the base plate body 100 (the strip cavity 301 is distributed along the width direction of the base plate body 100 and is formed by the connecting strips 300 and the base plate body 100). At least one connecting strip 300 is provided between two adjacent wheel arch receiving structures 200. This allows part of the load of the vehicle cabin and the equipment inside the vehicle cabin to be borne by the wheel arch receiving structure 200 and the connecting strips 300 respectively (and then transferred to the base plate body 100 by the wheel arch receiving structure 200 or the connecting strips 300), instead of the entire load being directly borne by the base plate body 100, thereby optimizing the stress distribution of the load.
[0028] The vertical height of the wheel arch 210 relative to the base plate body 100 is significantly higher than that of the connecting strip 300 relative to the base plate body 100, in order to further optimize the load distribution.
[0029] The wheel arch body 210 is provided with a wheel arch main body 211 and a wheel arch bending part 212 integrally formed with the wheel arch main body 211. The wheel arch main body 211 and the wheel arch bending part 212 together form an open wheel arch cavity 213 so that the wheel hub can be accommodated by the open wheel arch cavity 213.
[0030] The connecting strip 300 includes a main body section 302 and two extension sections 303. The two extension sections 303 are located at the two ends of the main body section 302 and are integrally formed with the two ends of the main body section 302.
[0031] Among them, the main body segment 302 of the connecting strip is directly opposite the base plate body 100 (in the width direction), and the extension segment 303 of the connecting strip extends out from the base plate body 100; that is, the orthographic projection of the main body segment 302 of the connecting strip exactly covers the width direction of the base plate body 100, and the orthographic projection of the extension segment 303 of the connecting strip does not cover the base plate body 100.
[0032] It is worth mentioning that the specific components and other technical features of the integrated vehicle chassis involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.
[0033] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
