Abstract
Description
Technical Field
[0001] The present application relates to the technical field of commercial vehicles, and in particular to a commercial vehicle roof and a commercial vehicle. Background Art
[0002] The roof of a commercial vehicle's interior is made of spliced components made of composite materials. In existing roof structures, a 2mm gap is reserved between the two components along the extension direction of the slot structure in the splicing slot. Therefore, deformation between the two components is less restricted, and the gap between the two components at the splicing position is unevenly distributed. Utility Model Content
[0003] The purpose of the present application is to provide a commercial vehicle roof and a commercial vehicle to improve the problem of uneven distribution of the gap between two components at the plug-in position.
[0004] The embodiment of the present application is implemented as follows:
[0005] In a first aspect, an embodiment of the present application provides a commercial vehicle roof, comprising a first guard plate and a second guard plate, wherein a groove structure is provided at an edge of the first guard plate, and the groove structure comprises a first side wall, a second side wall and a bottom wall; the first side wall comprises a first area and a second area alternately arranged along an edge of the first guard plate; a first protrusion is provided in the first area, the first protrusion contacts one side of the second guard plate, the second side wall contacts the other side of the second guard plate, and there is a gap between the second area of the first side wall and the second guard plate.
[0006] In the above technical solution, the second guard plate extends into the groove structure of the first guard plate to achieve a plug-in connection. Since the first area of the first side wall of the groove structure is provided with a first protrusion, the first protrusion contacts one side of the second guard plate, and the second side wall contacts the other side of the second guard plate. Therefore, in the first area, the first protrusion and the second side wall can contact the second guard plate to play a positioning and limiting role on the second guard plate, so as to reduce the deformation of the second guard plate, thereby improving the problem of uneven gap between the first and second guard plates at the plug-in position. There is a gap between the second area of the first side wall and the second guard plate, which can facilitate the insertion of the second guard plate into the groove structure of the first guard plate. That is, in the above technical solution, the first protrusion and the second side wall can contact the guard plate from both sides of the second guard plate, thereby playing a positioning role on the second guard plate, thereby reducing the deformation of the second guard plate. At the same time, since the first side wall has a gap between the second area and the second guard plate, it can facilitate the insertion of the second guard plate into the groove structure of the first guard plate. During production, the precision requirements for the first guard plate are primarily focused on the first protrusion, which reduces the precision requirements for other locations. This also reduces the precision requirements for the second guard plate to a certain extent, thereby reducing costs. Because the first and second regions are arranged alternately, the first protrusion and second sidewall at each interval act to limit and position the second guard plate. This means that each end distance limits deformation of the second guard plate, minimizing the impact of deformation on its overall appearance.
[0007] In some optional embodiments, the first protrusion includes a first section and a second section, and the first section is inclined so that the first section can play a guiding role during the insertion of the second guard plate into the groove structure; one side of the second guard plate contacts the second section and the other side contacts the second side wall.
[0008] In the above technical solution, the second section and the second side wall play a role in positioning the second guard plate, and the first section can play a guiding role in the process of inserting the second guard plate into the groove structure, thereby facilitating the installation of the second guard plate and reducing the difficulty of installation caused by deformation of the second guard plate.
[0009] In some optional embodiments, the bottom wall is provided with a second protrusion, the second protrusion is connected to the second section, the second guard plate is in contact with the second protrusion, and there is a gap between the second guard plate and the bottom wall.
[0010] In the above technical solution, the second protrusion can limit the second guard plate in the direction of inserting the second guard plate into the slot structure, reducing the precision requirements of the slot structure and the second guard plate in this direction, thereby reducing the processing cost of the slot structure.
[0011] In some optional embodiments, the protrusion heights of the first protrusion and the second protrusion are between 1 and 3 mm.
[0012] The protruding heights of the first protrusion and the second protrusion are within the above range, which can not only play the role of positioning the second guard plate, but also ensure that the gap between the second guard plate and the second area, as well as the gap between the bottom walls of the groove structure are within a reasonable range, thereby reducing the processing accuracy requirements for the groove structure and the second guard plate, and not causing a significant increase in the size of the first guard plate.
[0013] In some optional embodiments, the dimensions of the first protrusion and the second protrusion in the extension direction of the groove structure are between 10 and 20 mm.
[0014] The width dimensions of the first section and the second protrusion are within the above range, so that the first protrusion and the second protrusion can play a better limiting role on the second guard plate.
[0015] In some optional embodiments, the first protrusion and the second protrusion are located at the same position in the extension direction of the groove structure.
[0016] In the above technical solution, the first protrusion and the second protrusion are at the same position in the extension direction of the groove structure, which plays a limiting role on the second guard plate and can have a better limiting effect on the second guard plate.
[0017] In some optional embodiments, in the extension direction of the groove structure, the interval between two adjacent first protrusions is 200 to 500 mm.
[0018] In the above technical solution, the first protrusions are arranged according to the above intervals, which can not only limit the second guard plate, but also reduce the situation where the second guard plate is difficult to insert into the groove structure due to large deformation.
[0019] In some optional embodiments, the extending direction of the groove structure has a corner, and the first protrusion and the second protrusion are provided at the corner.
[0020] At locations with corners in the direction of extension of the slot structure, the second guard plate can be difficult to insert into the slot structure. In the above technical solution, by providing a first protrusion and a second protrusion at the corners, the first section of the first protrusion can guide the second guard plate during installation, facilitating its insertion. Furthermore, because the first and second protrusions at the corners limit the second guard plate, the second guard plate can be positioned correctly relative to the first guard plate at the corners, reducing the difficulty of inserting the second guard plate into the slot structure from locations other than the corners.
[0021] In some optional embodiments, the second guard plate includes a plate body and a folded edge located at the edge of the plate body, the folded edge contacts the second section away from the edge of the plate body and contacts the second side wall close to the edge of the plate body; the folded edge contacts the second protrusion away from the side of the plate body.
[0022] In the above technical solution, the second guard plate includes a plate body and a folded edge at the edge of the plate body. The two edges of the folded edge contact the second section and the second sidewall, respectively, and one side also contacts the second protrusion. This means that the folded edge is susceptible to deformation during insertion into the slot structure. Therefore, if the second guard plate's dimensions have precision errors and are slightly larger than the slot structure, the second guard plate can deform at the junction of the plate body and the folded edge to allow insertion into the slot structure, thereby reducing the dimensional precision requirements for the second guard plate.
[0023] In a second aspect, an embodiment of the present application provides a commercial vehicle, comprising the commercial vehicle roof provided in the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The embodiment of the present application provides a commercial vehicle, including a commercial vehicle roof for the interior of the cab. Figure 1 and Figure 2As shown, the commercial vehicle roof includes a first guard plate 100 and a second guard plate 200. The edge of the first guard plate 100 is provided with a groove structure 110, and the second guard plate 200 is inserted into the groove structure 110 to achieve a connection between the first guard plate 100 and the second guard plate 200. The first guard plate 100 and the second guard plate 200 are both composite structural parts. After molding, they are connected to the metal frame structure of the cab via snap fasteners.
[0037] like Figure 2 As shown, the groove structure 110 includes a first side wall 111 , a second side wall 112 and a bottom wall 113 ; the first side wall 111 includes a first area 141 and a second area 142 alternately arranged along the edge of the first guard plate 100 ; the first area 141 is provided with a first protrusion 120 .
[0038] like Figure 3 and Figure 4 As shown, when the second guard plate 200 is inserted into the slot structure 110, the first protrusion 120 contacts one side of the second guard plate 200, and the second side wall 112 contacts the other side of the second guard plate 200. The first protrusion 120 and the second side wall 112 can limit and position the second guard plate 200, specifically, limit and position the second guard plate 200 in the width direction of the slot structure 110. Figure 4 As shown, when the second guard plate 200 is inserted into the groove structure 110, there is a gap between the second area 142 of the first side wall 111 and the second guard plate 200. Due to the existence of the gap, the second guard plate 200 can be more easily inserted into the position corresponding to the second area 142 in the groove structure 110.
[0039] Since the first area 141 and the second area 142 are alternately arranged along the edge of the first guard plate 100, when the second guard plate 200 is inserted into the groove structure 110, the second guard plate 200 is limited and positioned by the first protrusion 120 and the second side wall 112 at every interval, that is, the deformation of the second guard plate 200 is restricted once at every interval, so that the overall deformation of the second guard plate 200 is smaller, which can reduce the impact of the deformation on the overall appearance of the second guard plate 200; and the gap between the second guard plate 200 and the second area 142 of the first side wall 111 can be more uniform.
[0040] In some embodiments, the first protrusion 120 includes a first section 121 and a second section 122. The first section 121 is tilted so that it can guide the second guard plate 200 during insertion into the slot structure 110. The second section 122 is configured to contact the second guard plate 200 and, together with the second sidewall 112, limit the second guard plate 200. That is, when the second guard plate 200 is located within the slot structure 110, one side of the second guard plate 200 contacts the second section 122 and the other side contacts the second sidewall 112. It is understood that the first section 121 should be located at the slot opening of the slot structure 110 and have an inclined or smoothly transitioned surface that connects to the surface of the second section 122 that contacts the second guard plate 200. This allows the second guard plate 200 to be smoothly inserted between the second section 122 and the second sidewall 112 during insertion into the slot structure 110 under the action of the first section 121.
[0041] In some embodiments, the protruding height of the first section 121 is the same as the protruding height of the second section 122. In this embodiment, the first sidewall 111 can be tilted outward at the notch position so that the notch is larger than the size of the bottom wall 113. Therefore, the first section 121 disposed near the notch position of the first sidewall 111 is also tilted accordingly, so that the surface of the first section 121 facing the second sidewall 112 has a guiding function. Alternatively, the thickness of the first section 121 can gradually decrease in the direction away from the second section 122, so that the surface of the first section 121 facing the second sidewall 112 has a guiding function. Furthermore, the protruding height of the first protrusion 120 is between 1 and 3 mm, that is, the first section 121 is higher than the first sidewall 111, and the second section 122 is also higher than the first sidewall 111. Specifically, the height can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm.
[0042] Furthermore, both sides of the first section 121 are flush with both sides of the second section 122, that is, one side surface of the first section 121 and the corresponding side surface of the second section 122 are located on the same surface, and the other opposite side surface of the first section 121 and the corresponding side surface of the second section 122 are also located on the same surface.
[0043] In some embodiments, the bottom wall 113 is further provided with a second protrusion 130. The second protrusion 130 is connected to the second section 122, and the second guard plate 200 also contacts the second protrusion 130, with a gap between the second guard plate 200 and the bottom wall 113. It is not difficult to understand that in this embodiment, the second protrusion 130 can position the second guard plate 200 during its insertion into the slot structure 110. Therefore, the second protrusion 130 can position and limit the second guard plate 200 in the depth direction of the slot structure 110. Furthermore, the protrusion height of the second protrusion 130 is between 1 and 3 mm, that is, the surface of the second protrusion 130 that contacts the second guard plate 200 is higher than the bottom wall 113, specifically 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm. Preferably, the surface of the second protrusion 130 that contacts the second guard plate 200 is flat.
[0044] In some embodiments, the dimensions of the first protrusion 120 and the second protrusion 130 in the direction in which the groove structure 110 extends are between 10 and 20 mm. That is, the widths of the first protrusion 120 and the second protrusion 130 are between 10 and 20 mm, specifically 10 mm, 15 mm, or 20 mm. The widths of the first protrusion 120 and the second protrusion 130 are the dimensions of the first protrusion 120 and the second protrusion 130 in the width direction.
[0045] Furthermore, in some embodiments, the first protrusion 120 and the second protrusion 130 are located at the same position in the extending direction of the groove structure 110, such as Figure 2 As shown, the two side surfaces of the first protrusion 120 perpendicular to the extension direction of the groove structure 110 and the two side surfaces of the second protrusion 130 perpendicular to the extension direction of the groove structure 110 are flush with each other. Furthermore, the first protrusion 120 and the second protrusion 130 are integrally formed. In this embodiment, the first protrusion 120 and the second protrusion 130 can be easily formed. In other embodiments, the first protrusion 120 and the second protrusion 130 can also be staggered in the extension direction of the groove structure 110.
[0046] Furthermore, in some embodiments, the spacing between two adjacent first protrusions 120 is between 200 and 500 mm, specifically 200 mm, 300 mm, 400 mm, or 500 mm. It is readily understood that the smaller the spacing between the two first protrusions 120, the more second guard plates 200 can act as position limiters for the first protrusions 120, further minimizing deformation of the second guard plates 200 and facilitating insertion of the second guard plates 200 into the slot structure 110. Furthermore, the gap between the second guard plates 200 and the second region 142 is more uniform, resulting in a better appearance for the commercial vehicle roof.
[0047] In some embodiments, the second guard plate 200 includes a plate body 210 and a folded edge 220 located at the edge of the plate body 210. The edge of the folded edge 220 away from the plate body 210 contacts the second section 122 of the first protrusion 120, and the edge closer to the plate body 210 contacts the second sidewall 112. The side of the folded edge 220 away from the plate body 210 contacts the second protrusion 130. It is easy to understand that the second guard plate 200 is a plate-shaped structural member, and accordingly, the folded edge 220 is a structural member with a relatively small thickness. When the second guard plate 200 is installed in the slot structure 110, the side of the folded edge 220 away from the plate body 210 is the side facing the bottom wall 113. In this embodiment, the strength of the connection between the plate body 210 and the folded edge 220 is relatively small, and the strength of the folded edge 220 itself is also relatively small. When the first protrusion 120 and the second side wall 112 are used to limit and position the second guard plate 200 at the same time, if the size of the second guard plate 200 is larger than the design size, then in the process of installing the second guard plate 200 into the groove structure 110, the folded edge 220 will be squeezed with the first protrusion 120 and the second side wall 112 at the same time, causing the folded edge 220 to deform and be inserted between the first protrusion 120 and the second side wall 112. That is, in this embodiment, even if there is a certain error in the size of the second guard plate 200 or the groove structure 110, the deformation of the folded edge 220 can enable the second guard plate 200 to be inserted into the groove structure 110, which can reduce the dimensional accuracy requirements of the second guard plate 200 and the groove structure 110.
[0048] Furthermore, in some embodiments, the extending direction of the groove structure 110 has a corner 114, and a first protrusion 120 and a second protrusion 130 are provided at the corner 114. Figure 1As shown, in some embodiments, a first guard plate 100 is mounted on the top rear side of the cab. A slot structure 110 extends along the top edge and two vertical edges of the first guard plate 100. The slot structure 110 has a corner 114 where the vertical edge intersects the top edge. A second guard plate 200 is mounted in the middle of the cab top and has side wings 230 extending to both sides of the cab top near the left and right doors. A portion of the second guard plate 200 is inserted into the slot structure 110 located at the top of the first guard plate 100, and the edges of the second guard plate 200 located at the side wings 230 are inserted into the vertically extending slot structure 110 located in the first guard plate 100.
[0049] Combine Figure 1 and Figure 2 It is easy to understand that the top edge of the first guard plate 100 has a corner 114 at each end, and the slot structure 110 can be divided into a horizontal section located between the two corners 114 and two vertical sections extending in the vertical direction, each of which is connected to one end of the horizontal section. The first protrusion 120 and the second sidewall 112 located at the two corners 114 can, to a certain extent, limit and position the second guard plate 200 inserted into the horizontal section in the horizontal direction, and to a certain extent, limit and position the second guard plate 200 inserted into the vertical section in the vertical direction, making it more convenient to install the second guard plate 200 into the slot structure 110.
[0050] In some other embodiments, the first guard plate 100 may be installed at the top middle position of the cab, and the second guard plate 200 may be installed at the top rear side of the cab.
[0051] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
