Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a floor assembly, a single-row cab, a semi-cab cab, and a vehicle. Background Technology
[0002] Light-duty vehicles can be equipped with engines of different power outputs depending on their intended use. When a smaller engine is selected, its smaller size means it doesn't require additional space in the cab, allowing for a flat floor in the driver's seat area, thus increasing the space for the driver and passengers. Conversely, when a larger engine is selected, its larger size requires additional space in the cab, necessitating a raised floor in the driver's seat area to accommodate it.
[0003] In related technologies, in order to simplify the process, the floor assembly of the cab is usually manufactured by vacuum die casting. This results in the floor assemblies for different types of cabs not being interchangeable. Two or more sets of vacuum die casting molds are required to die cast different specifications of floor assemblies, which leads to a significant increase in mold development costs.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0037] like Figures 1-12 As shown, this utility model provides a floor assembly applicable to various types of cabs. The floor assembly includes a front floor 1 and a middle floor 2. The front floor 1 is provided with a first overlapping structure 101. The middle floor 2 is a flat floor or a raised floor. The flat floor or the raised floor is provided with a front connecting part 21. The front connecting part 21 is provided with a second overlapping structure 102. The second overlapping structure 102 cooperates with the first overlapping structure 101 and is welded to the first overlapping structure 101, preferably by spot welding. The flat floor or the raised floor is welded to the front floor 1 to form floor assemblies of different specifications. Specifically, when the middle floor 2 is a flat floor, the flat floor is also provided with a flat plate part 22a integrally formed with the front connecting part 21. The flat plate part 22a corresponds to the installation position of the seat and is straight along the width direction of the cab to ensure the flatness of the floor assembly. When the middle floor 2 is a raised floor, it also has a protrusion 22b integrally formed with the front connecting part 21. The protrusion 22b corresponds to the seat installation position, and along the width direction of the cab, the middle part of the protrusion 22b protrudes upward, providing sufficient space for engine placement and meeting the user's needs for selecting high-power or large-size engines. In addition, both the flat part 22a of the flat floor and the protrusion 22b of the raised floor are provided with a third overlapping structure 103, which is welded to the fourth overlapping structure 104 of the rear assembly 30. The dimensions of the flat floor and the raised floor are equal in the length and width directions of the cab, further improving the interchangeability of the flat floor and the raised floor. According to user needs, the flat floor can be welded to the front floor 1 to form a flat cab floor with high flatness; or the raised floor can be welded to the front floor 1 to form a cab floor with a raised middle part, which can meet the placement requirements of larger-size engines. The floor assembly of this embodiment welds the front floor 1 and the middle floor 2 together, and the middle floor 2 is set as a flat floor or a raised floor. It is welded to the front floor 1 through the second overlapping structure 102 and the first overlapping structure 101 of the front floor 1, thereby improving the versatility of floor assembly parts of different specifications, reducing the types of parts, and thus reducing the development cost of molds.
[0038] Specifically, the upward protrusion height of the middle portion of the raised part 22b of the raised floor is determined according to the size of the engine. In this embodiment, the upward protrusion height of the middle portion of the raised part 22b of the raised floor is 80mm-160mm, for example, it can be 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, 150mm, 155mm, or 160mm. In this embodiment, the upward protrusion height of the middle portion of the raised part 22b is preferably 110mm.
[0039] Furthermore, the floor assembly also includes two side beams 4, which are welded to both sides of the front floor 1 and to both sides of the middle floor 2, respectively. By providing two side beams 4, the structural strength of the floor assembly is enhanced.
[0040] Furthermore, the floor assembly also includes a rear floor 3. The front end of the rear floor 3 is provided with a fourth overlapping structure 104, and the rear end of the rear floor 3 is provided with a third overlapping structure 103. The rear floor 3 is welded to the third overlapping structure 103 of the middle floor 2 through the fourth overlapping structure 104. The third overlapping structure 103 of the rear floor 3 is used to weld to the fourth overlapping structure 104 of the rear bulkhead assembly 30. By setting the rear floor 3, the needs of cabs of different lengths are further met. The front end and rear end of the rear floor 3 are respectively provided with the fourth overlapping structure 104 and the third overlapping structure 103. When the floor assembly needs to be used in a short cab, the rear bulkhead assembly 30 is directly welded to the rear end of the middle floor 2. When the floor assembly needs to be used in a longer cab, the rear floor 3 is welded to the rear end of the middle floor 2, and the rear bulkhead assembly 30 is welded to the rear end of the rear floor 3, thereby improving versatility and the convenience of switching between different types of cabs.
[0041] Specifically, a sleeper bracket 31 is fixedly installed on the rear floor 3. The sleeper bracket 31 is used to support the sleeper board and provide a rest space for the driver and passengers. At the same time, the sleeper bracket 31 can also strengthen the structural strength of the floor assembly to a certain extent.
[0042] Correspondingly, for the floor assembly that also includes a rear floor 3, two corresponding side beams 4 are also included. The two side beams 4 are welded to both sides of the front floor 1, both sides of the middle floor 2, and both sides of the rear floor 3. By providing two side beams 4, the structural strength of the floor assembly is enhanced. In other embodiments, for the floor assembly with a rear floor 3, the side beams 4 can also be welded only to the front floor 1 and the middle floor 2. That is, the same specification of side beams 4 is used in floor assemblies with only the front floor 1 and the middle floor 2, as well as floor assemblies with the front floor 1, middle floor 2, and rear floor 3, thereby achieving the universality of the side beams 4 and reducing the types of parts.
[0043] Specifically, the floor assembly in this embodiment can be combined into various structures through the reasonable arrangement of the front floor 1, the middle floor 2, and / or the rear floor 3. For example, for a cab with a shorter required length, i.e., a single-row cab, and where the selected engine size does not require space in the cab, the front floor 1 and the middle floor 2 are welded together, and the middle floor 2 is set as a flat floor, as detailed in the following reference. Figure 4 As shown; for applications requiring a single-row cab and where the selected engine size occupies cab space, the front floor 1 and the middle floor 2 are welded together, with the middle floor 2 being a raised floor, as detailed in the following reference. Figure 6 As shown. For example, for a cab requiring a longer length, i.e., a semi-cab, and where the selected engine size does not require additional cab space, the front floor 1 and middle floor 2 are welded together, and the middle floor 2 and rear floor 3 are welded together. The middle floor 2 is designed as a flat floor. See [reference needed] for details. Figure 7 As shown; for applications requiring a single-row cab and where the selected engine size occupies cab space, the front floor 1 and middle floor 2 are welded together, and the middle floor 2 and rear floor 3 are welded together. The middle floor 2 is designed as a raised floor. See the attached diagram for details. Figure 8 As shown. The front floor 1 is as follows.
