[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0042] The dash panel is mounted on the body-in-white (BW) (i.e., mounted above the cab), while the bumper is mounted on the frame (i.e., mounted below the cab), resulting in a large gap between the dash panel and the bumper. To reduce this gap, lower wind resistance, and improve vehicle refinement, the present invention provides a cab.

[0043] like Figure 1 and Figure 2As shown, the cab includes a body-in-white 130, a front outer panel 1510 and a bumper assembly, wherein the upper part of the front outer panel 1510 is fixedly connected to the body-in-white 130; the bumper assembly includes a bumper frame 110, a bumper air intake grille 1610 and a bumper decorative strip, the bumper frame 110 is mounted on the body-in-white 130, the lower part of the front outer panel 1510 is fixedly connected to the bumper assembly, the bumper air intake grille 1610 is arranged between the front outer panel and the bumper mask 140, and the bumper mask 140 is connected to the bumper frame 110.

[0044] In the cab provided by the present invention, since both the front outer panel 1510 and the bumper assembly are installed on the body-in-white 130, compared with the related art in which one of the panels is installed on the body-in-white 130 and the other is installed on the frame, the gap between the front outer panel 1510 and the bumper assembly set on the body-in-white 130 can be adjusted according to the positions of the two, thereby reducing the gap between the front outer panel 1510 and the bumper assembly. The reduced gap can reduce wind resistance and improve the refinement of the vehicle.

[0045] In this embodiment, the cab further includes a corner panel, one on each side of the front outer panel, which is mounted on the body-in-white 130 and spaced apart from the front outer panel 1510. For ease of distinction, the corner panels on either side of the front outer panel 1510 are divided into left corner panels 1520 and right corner panels 1530, wherein the left corner panel 1520 is provided on one side of the front outer panel 1510, and the right corner panel 1530 is provided on the other side. Figure 1 As shown, along the forward direction of the cab, the corner panel located on the left side of the front outer panel 1510 is the left corner panel 1520, and the corner panel located on the right side of the front outer panel 1510 is the right corner panel 1530. The provision of the left corner panel 1520 and the right corner panel 1530 can serve as aesthetic decoration.

[0046] Furthermore, the front outer panel 1510 is a metal part, which can improve the overall strength of the front outer panel 1510 and prevent the front outer panel 1510 from being shattered during a collision. It should be noted that the upper part of the front outer panel 1510 is connected and fixed to the lower cross beam 138 of the windshield of the white body 130, and the lower part of the front outer panel 1510 is fixedly connected to the bumper frame 110 to fix the front outer panel 1510.

[0047] like Figure 7As shown, the front outer panel 1510 includes an upper left portion 1511, a lower left portion 1512, an upper right portion 1513 and a lower right portion 1514 of the front outer panel. The upper left portion 1511 of the front outer panel is connected and fixed to the lower cross beam 138 of the windshield of the body-in-white 130, the lower left portion 1512 of the front outer panel is connected and fixed to the bumper frame 110, the upper right portion 1513 of the front outer panel is connected and fixed to the lower cross beam 138 of the windshield of the body-in-white 130, and the lower right portion 1514 of the front outer panel is connected and fixed to the bumper frame 110.

[0048] In some embodiments, as Figure 3 As shown, the bumper assembly further includes a bumper middle cross member 120 , which strengthens, fixes and supports the bumper frame 110 . The bumper middle cross member 120 is installed on the front side of the body-in-white 130 to protect the body-in-white 130 .

[0049] Specifically, if Figure 4 and Figure 6 As shown, the bumper frame 110 includes a first bumper frame portion 111, a second bumper frame portion 112, and a third bumper frame portion 113, which are connected in sequence. The body-in-white 130 includes a front panel middle bracket 131, a first side panel upper bracket 132, a first side panel lower bracket 133, a second side panel upper bracket 134, a second side panel lower bracket 135, a first floor bracket 136, and a second floor bracket 137. The first side panel upper bracket 132 and the second side panel upper bracket 134 are respectively provided on both sides of the upper portion of the front panel middle bracket 131, and the first side panel lower bracket 133 and the second side panel lower bracket 135 are respectively provided on both sides of the lower portion of the front panel middle bracket 131. The first floor bracket 136 and the second floor bracket 137 are respectively provided on both sides of the bottom of the front panel middle bracket 131.

[0050] For example, the first bumper frame part 111, the second bumper frame part 112, and the third bumper frame part 113 are connected by welding, that is, one end of the second bumper frame part 112 is welded to the first bumper frame part 111, and one end of the second bumper frame part 112 is welded to the third bumper frame part 113.

[0051] Specifically, the first bumper frame portion 111 is connected and fixed to the first side panel upper bracket 132, the first side panel lower bracket 133, and the bumper center cross member 120. The third bumper frame portion 113 is connected to the second side panel upper bracket 134 and the second side panel lower bracket 135, and is also connected and fixed to the bumper center cross member 120. The second bumper frame portion 112 is connected and fixed to the bumper center cross member 120 and the front panel center bracket 131. In this way, the bumper frame 110 is fixedly connected to the body-in-white 130, ensuring that the bumper assembly is mounted on the body-in-white 130 through multiple mounting points, improving the stability of the connection between the bumper assembly and the body-in-white 130, and preventing the bumper assembly from separating directly from the body-in-white 130 after a collision.

[0052] In some embodiments, as Figure 5 As shown, the bumper center cross member 120 includes a tubular beam 121, two center cross member brackets, and two tubular beam connecting brackets. A tubular beam connecting bracket is provided at each end of tubular beam 121. A center cross member bracket is provided on tubular beam 121, with the two center cross member brackets spaced apart and positioned between the two tubular beams 121. A first floor bracket 136 is fixedly connected to one of the center cross member brackets, and a second floor bracket 137 is fixedly connected to the other. Therefore, the two tubular beam connecting brackets connect tubular beam 121 to the corresponding first floor bracket 136 and second floor bracket 137, thereby improving the connection stability of the bumper center cross member 120 and ensuring a secure connection between the bumper center cross member 120 and the body-in-white 130.

[0053] It should be noted that one of the two middle crossbeam supports is the middle crossbeam left support 122 , and the other is the middle crossbeam right support 123 ; one of the two pipe beam connecting supports is the pipe beam left connecting support 124 , and the other is the pipe beam right connecting support 125 .

[0054] In some embodiments, the bumper cover 140 is further fixedly connected to the bumper center cross member 120 and the body-in-white 130 .

[0055] As you can understand, the bumper fascia 140 is made of fiberglass. Its relative density is between 1.5 and 2.0, only one-fourth to one-fifth that of carbon steel. However, its tensile strength approaches or even exceeds that of carbon steel, and its specific strength is comparable to that of high-grade alloy steel. Therefore, it is highly effective in applications such as aviation, rockets, spacecraft, high-pressure vessels, and other products requiring reduced weight. The bumper fascia 140, therefore, possesses relatively high strength, protecting the dash panel 1510 and, in turn, the engine and other components located within it.

[0056] like Figures 8-11As shown, in some embodiments, in order to reduce wind resistance and improve the overall refinement of the cab 10, the gap between the left corner panel 1520 and the front outer panel 1510 is less than or equal to 2 mm, and the gap L2 between the right corner panel 1530 and the front outer panel 1510 is less than or equal to 2 mm; the gap L5 between the bumper air intake grille 1610 and the front outer panel 1510 is less than or equal to 2 mm, and the gap L6 between the bumper air intake grille 1610 and the bumper mask 140 is less than or equal to 2 mm; the gap between the bumper decorative strip and the bumper air intake grille 1610 is less than or equal to 2 mm, the gap between the bumper decorative strip and the adjacent corner panel is less than or equal to 2 mm, and the gap between the bumper decorative strip and the bumper mask 140 is less than or equal to 2 mm.

[0057] The bumper decorative strips include a left bumper decorative strip 1620 and a right bumper decorative strip 1630. The left bumper decorative strip 1620 is installed on the left side of the bumper air intake grille 1610, the lower part of the left corner plate 1520, and the upper part of the bumper mask 140. The gap L1 between the left bumper decorative strip 1620 and the bumper air intake grille 1610 is less than or equal to 2 mm, the gap L4 between the left bumper decorative strip 1620 and the left corner plate 1520 is less than or equal to 2 mm, and the gap L3 between the left bumper decorative strip 1620 and the bumper mask 140 is less than or equal to 2 mm.

[0058] Preferably, the right bumper decorative strip 1630 is installed on the right side of the bumper air intake grille 1610, the lower part of the right corner plate 1530, and the upper part of the bumper mask 140. The gap between the right bumper decorative strip 1630 and the bumper air intake grille 1610 is less than or equal to 2 mm, the gap between the right bumper decorative strip 1630 and the right corner plate 1530 is less than or equal to 2 mm, and the gap between the right bumper decorative strip 1630 and the bumper mask 140 is less than or equal to 2 mm.

[0059] The present invention provides a cab having an integrated front outer panel 1510 and a bumper assembly, and a refined design in which the gaps between the various parts are less than or equal to 2 mm, thereby effectively reducing the air resistance of the entire vehicle.

[0060] In addition, the present invention further provides a vehicle, which includes a vehicle frame 30 , a suspension bracket 20 and a cab 10 provided by the present invention, wherein the vehicle frame 30 is connected to the cab 10 via the suspension bracket 20 .

[0061] Since the vehicle includes the cab 10 provided by the present invention, both the front outer panel 1510 and the bumper assembly are installed on the body-in-white 130. Compared with the related art in which one of them is installed on the body-in-white 130 and the other is installed on the frame 30, the gap between the front outer panel 1510 and the bumper assembly set on the body-in-white 130 can be adjusted according to the positions of the two, thereby reducing the gap between the front outer panel 1510 and the bumper assembly. The reduced gap can reduce wind resistance and improve the refinement of the vehicle.

[0062] In some embodiments, as Figure 12 As shown, the suspension bracket 20 includes a front suspension bracket 210 and a rear suspension bracket 220, and the upper portion of the front suspension bracket 210 and the upper portion of the rear suspension bracket 220 are both connected to the body-in-white 130. The lower portion of the front suspension bracket 210 and the lower portion of the rear suspension bracket 220 are both connected to the vehicle frame 30.

[0063] The front end of the frame 30 is located at the bottom of the front end of the cab 10. The distance between the front end of the frame 30 and the front end of the cab 10 is h, where 55 mm ≤ h ≤ 65 mm. For example, h is 55 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, 61 mm, 62 mm, 63 mm, 64 mm, or 65 mm, which is not specifically limited in this embodiment. Of course, as a preferred embodiment, h is preferably 60 mm.

[0064] The front suspension bracket 210 ensures that the position of the roll axis remains unchanged, and the connection between the front suspension bracket 210 and the frame 30 is moved back 60 mm. For the front suspension bracket 210, it is equivalent to a 60 mm cantilever design, which increases the design difficulty of the stiffness and strength of the front suspension bracket 210.

[0065] Furthermore, by moving the vehicle frame 30 backward, designing the front suspension bracket 210 forward, and designing the front cross beam 31 with a chamfered slope to avoid the problem, the cab 10 can be flipped over for maintenance at a large angle.

[0066] like Figure 13 As shown, the front cross beam 31 is provided with a chamfered surface. For example, the chamfered surface is 45 degrees, which can ensure that the tilting angle of the cab 10 is not less than 40 degrees.

[0067] It should be noted that the front suspension bracket 210 ensures that the position of the tilt axis 211 remains unchanged. The front suspension bracket 210 is provided with a 60 mm cantilever design, and the front crossbeam 31 of the frame 30 is provided with a 45-degree chamfered slope avoidance design.

[0068] Preferably, the vehicle comprises a cab 10 with an integrated front wall, a suspension bracket 20 and a vehicle frame 30. Figure 13 The cab 10 with the integrated front panel can be flipped forward 40 degrees along the rotation axis 211. After flipping, the cab 10 with the integrated front panel maintains a safe distance from the front crossbeam 31 of the vehicle frame.

[0069] Furthermore, the front crossbeam 31 of the frame is provided with a 45-degree chamfered slope avoidance design, which increases the difficulty of designing the rigidity and strength of the frame 30 .

[0070] Since the vehicle includes the above-mentioned cab, the vehicle of the embodiment of the present invention has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be described in detail here.

[0071] Furthermore, the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
