[0054] Exemplary embodiments according to the present application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in various different forms, and should not be interpreted as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided in order to make the present disclosure complete and comprehensive, and to adequately convey the ideas of these exemplary embodiments to those of ordinary skill in the art. In the drawings, the thickness of layers and regions can be exaggerated for clarity, and the same reference numerals are used to denote the same elements, so that a description thereof will be omitted.

[0055] In the field of domestic and foreign commercial vehicles, long-distance transportation is its core application scenario, and drivers often need to drive for a long time. During the parking and rest phase, the sleeper area of the cab becomes the core space for the driver to eat and take a short break.

[0056] However, the current design of the sleeper area of a commercial vehicle generally has the defect of single function and lacks an adaptive storage table structure. In actual use, the driver can only place the food on the knees or the edge of the sleeper when eating, which not only easily causes the food to spill and affects the eating experience, but also has the risk of scalding. At the same time, common personal electronic devices such as mobile phones, tablets and navigation devices, as well as water cups, identification cards and driving data, also have no special storage location and can only be placed randomly on the sleeper or the floor of the cab, which not only easily causes loss, sliding and damage, but also brings great inconvenience to the driver, seriously reducing the convenience and comfort of the sleeper area.

[0057] On the other hand, in the actual operation of a commercial vehicle, single-person driving conditions account for a considerable proportion. In this condition, the co-driver seat is in an idle state for a long time, but the co-driver seat of most existing commercial vehicles is designed with a fixed structure and does not have a folding storage function. The idle co-driver seat occupies a large amount of effective space in the cab, not only compresses the movement range of the driver in the cab, but also hinders the passage in the cab, reducing the space utilization and passability of the cab. Especially when temporary placement of goods, tools and other articles is needed in the cab, the limited space cannot meet the actual use demand, causing many troubles to the daily work and rest of the driver.

[0058] In summary, the deficiencies of the existing commercial vehicle cab in the function configuration of the sleeper area and the structure design of the co-driver seat cannot match the demand of the driver for the space utilization efficiency and use comfort of the cab, and a technical solution that can simultaneously solve the problems of the sleeper area storage demand and the space occupation of the co-driver seat is urgently needed.

[0059] In combination with Figures 1 to 7 , according to the specific embodiments of the present application, a commercial vehicle fairing structure is provided.

[0060] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , a commercial vehicle fairing structure and a seat structure, comprising: a seat backrest, the seat backrest comprising a first backrest assembly 10 and a second backrest assembly 20, the first backrest assembly 10 being located above the second backrest assembly 20, one end of the first backrest assembly 10 being movably connected with one end of the second backrest assembly 20, the first backrest assembly 10 being rotatably arranged relative to the second backrest assembly 20; an adjusting assembly 50, the adjusting assembly 50 being located on one side of the seat backrest, one end of the adjusting assembly 50 being connected with the first backrest assembly 10, and the other end of the adjusting assembly 50 being connected with the second backrest assembly 20; wherein the adjusting assembly 50 is controlled to rotate the first backrest assembly 10 to rotate the first backrest assembly 10 to a horizontal working position in front of the vehicle.

[0061] By applying the technical solution of this invention, a seat back is provided consisting of a first backrest assembly 10 and a second backrest assembly 20 connected movably. The first backrest assembly 10 is rotated to a horizontal working position by the side adjustment assembly 50. Combined with the design of the seat cushion folding towards the backrest, the space occupied in the cab can be minimized when the seat is not in use. The horizontal structure formed after the backrest is folded can serve as a storage platform, accommodating the driver's dining table, mobile phone and tablet, and other personal items, as well as a temporary office desk. This effectively solves the pain points of traditional commercial vehicles, improves the space utilization and ease of use of the cab, and solves the technical problem of low space utilization in the cab of commercial vehicles in the prior art.

[0062] Furthermore, such as Figure 7 As shown, the seat structure also includes: a seat base assembly 30, which is located below the second backrest assembly 20 and is disposed at a distance from the adjustment assembly 50 and the first backrest assembly 10; the other end of the second backrest assembly 20 is movably connected to the seat base assembly 30; and a seat cushion assembly 40, which is located above the seat base assembly 30 and is disposed on one side of the second backrest assembly 20; one end of the seat cushion assembly 40 is movably connected to the seat base assembly 30. Controlling the rotation of the seat cushion assembly 40 allows it to be rotated to a folded position that contacts the second backrest assembly 20.

[0063] In this embodiment, the setting of keeping the seat base assembly 30 at a distance from the adjustment assembly 50 and the first backrest assembly 10 can avoid interference when the components move. The seat cushion assembly 40 can be rotated to a folded position that contacts the second backrest assembly 20, effectively reducing the space occupied by the seat when it is not in use and improving the utilization rate of the cab space.

[0064] Furthermore, when the first backrest assembly 10 is in the working position and the seat cushion assembly 40 is in the folded position, the other end of the seat cushion assembly 40 abuts against the front side of the first backrest assembly 10. This provides stable support for the first backrest assembly 10, improving its load-bearing capacity, while also limiting the mutual positioning of the two components to prevent wobbling or displacement of the parts, further enhancing the compactness and space utilization of the seat structure.

[0065] like Figures 4 to 6As shown, the first backrest assembly 10 includes: an upper backrest unit 101; an upper backrest frame 102, with the upper backrest unit 101 located on one side of the upper backrest frame 102, the upper backrest frame 102 connected to the upper backrest unit 101, one end of the upper backrest frame 102 movably connected to one end of the second backrest assembly 20, and one end of the adjustment component 50 connected to the upper backrest frame 102; and a table 103 located on the other side of the upper backrest frame 102, the table 103 connected to at least one of the upper backrest unit 101 and the upper backrest frame 102; wherein, the control adjustment component 50 can cause the adjustment component 50 to drive the upper backrest frame 102 to rotate, and when the first backrest assembly 10 is in the working position, the table 103 is located above the upper backrest frame 102 and the upper backrest unit 101 respectively.

[0066] In this embodiment, the first backrest assembly 10 integrates the upper backrest unit 101, the upper backrest frame 102, and the table 103, resulting in a compact and reasonable structural layout. The upper backrest frame 102 is connected to the upper backrest unit 101 to ensure basic support performance and is also connected to the adjustment component 50. The adjustment component 50 can drive the first backrest assembly 10 to rotate to the working position. At this time, the table 103 is located above the upper backrest frame 102 and the upper backrest unit 101, forming a convenient platform for placing items or dining, effectively solving the problem of drivers lacking suitable placement space in the cab.

[0067] Further, the second backrest assembly 20 includes: a lower backrest unit 201, which is located between the upper backrest unit 101 and the seat cushion assembly 40, with one end of the lower backrest unit 201 abutting against at least one of the lower backrest unit 201 and the table 103; a lower backrest frame 202, which is located on one side of the lower backrest unit 201 and connected to the lower backrest unit 201, with one end of the lower backrest frame 202 movably connected to one end of the upper backrest frame 102, the other end of the upper backrest frame 102 movably connected to the seat base assembly 30, and the other end of the adjustment assembly 50 movably connected to the upper backrest frame 102.

[0068] In this embodiment, the second backrest assembly 20 integrates the lower backrest unit 201 and the lower backrest frame 202, with a compact and reasonable structural design. The lower backrest frame 202 provides stable support for the lower backrest unit 201 and is movably connected to the upper backrest frame 102, the seat base assembly 30, and the adjustment assembly 50, respectively. It can cooperate with the adjustment assembly 50 to realize the rotation adjustment of the first backrest assembly 10. At the same time, the lower backrest unit 201 can abut against the table 103, further improving the overall stability of the seat structure.

[0069] In this embodiment, the upper backrest frame 102 includes: an upper frame 104, which is disposed at a distance from the second backrest assembly 20, and an adjustment component 50 disposed below the upper frame 104; a first connecting plate 105, which is located below the upper frame 104 and connected to the upper frame 104, with one end of the first connecting plate 105 movably connected to one end of the lower backrest frame 202; and a second connecting plate 108, which is located below the upper frame 104 and is spaced apart from the first connecting plate 105 along the width direction of the upper frame 104, connected to the upper frame 104, with one end of the second connecting plate 108 movably connected to one end of the lower backrest frame 202; wherein, the adjustment component 50 is located between the first connecting plate 105 and the second connecting plate 108, and one end of the adjustment component 50 is connected to one of the first connecting plate 105 and the second connecting plate 108.

[0070] In this embodiment, the upper backrest frame 102 adopts a combination structure of upper frame 104 with first connecting plate 105 and second connecting plate 108. The design of keeping the upper frame 104 at a distance from the second backrest assembly 20 can avoid interference when the components move. The first connecting plate 105 and the second connecting plate 108 are spaced apart along the width direction of the upper frame 104 and are both movably connected to the lower backrest frame 202, which can ensure the smoothness of the rotation adjustment of the first backrest assembly 10. At the same time, the adjustment component 50 is set below the upper frame 104 and between the first connecting plate 105 and the second connecting plate 108. The layout is compact and reasonable, which can improve the stability and reliability of the drive transmission of the adjustment component 50.

In this embodiment, the position of the third connecting plate 204 and the first connecting plate 105 can also be adjusted by connecting the adjusting handle 80 to the disc-type connecting angle adjuster 60.

[0072] In this embodiment, the lower backrest frame 202 adopts a combination structure of a lower frame 205 with a third connecting plate 204 and a fourth connecting plate 203. The design of keeping the lower frame 205 at a distance from the first backrest assembly 10 can avoid interference when the components move. The third connecting plate 204 and the fourth connecting plate 203 are spaced apart along the width direction of the lower frame 205 and are respectively movably connected to the connecting plate of the upper backrest frame 102, which can ensure the smoothness of the rotation adjustment of the backrest assembly. At the same time, the adjustment component 50 is set between the third connecting plate 204 and the fourth connecting plate 203, with a compact and reasonable layout, which can improve the stability and reliability of the drive transmission of the adjustment component 50.

[0073] In an exemplary embodiment, the seat base assembly 30 includes: a base unit 301, a first base connecting plate 302, and a second base connecting plate 303. The first base connecting plate 302 and the second base connecting plate 303 are respectively located on both sides of the base unit 301. The first base connecting plate 302 and the second base connecting plate 303 are respectively connected to the base unit 301. One end of the first base connecting plate 302 is hinged to the other end of the third connecting plate 204, and one end of the second base connecting plate 303 is hinged to the other end of the fourth connecting plate 203. The layout is well-organized. The first base connecting plate 302 and the second base connecting plate 303 are respectively located on both sides of the base unit 301 and connected to it, which not only strengthens the overall rigidity of the base, but also achieves stable linkage with the lower backrest frame 202 by being hinged to the third connecting plate 204 and the fourth connecting plate 203 respectively. This ensures the smoothness and accuracy of the backrest assembly during rotation and adjustment, and provides a reliable support foundation for the entire seat structure.
