[0002] The automobile cab roof assembly is an important component of the cab. The roof assembly is assembled on the top of the cab to increase the upper space of the cab.

[0003] At present, most of the cabs of light commercial vehicles are flat-top cabs, and most of the high-top cabs are non-metallic roof structures. The flat-top roof of the light cab is an integral sheet structure, and the upper part of the body-in-white side wall is in a "C" structure extending to the upper part of the roof, and is welded to the roof, and its welding edge is at the upper part of the body-in-white. Therefore, if the high-top roof is directly welded on the flat-top side wall, the Y-direction space at the body-in-white roof will be smaller than the Y-direction space of the side wall, and the internal space of the body-in-white cab will be smaller.

[0004] Therefore, there is an urgent need for a commercial vehicle cab roof connection structure and a vehicle to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a commercial vehicle cab roof connection structure, which increases the strength of the body-in-white and positions the welding edge closer to the outside of the body relative to a flat-top vehicle, thereby maximizing the internal space of the high-top cab body-in-white.

[0038] like Figure 1-Figure 2As shown, in this embodiment, the commercial vehicle cab roof connection structure is used to connect the roof 100 and the side panel 200, and the commercial vehicle cab roof connection structure includes a first connection plate 1, a first welding portion 2, a second welding portion 3, a second connection plate 4 and a third welding portion 5. Among them, the first connection plate 1 is a Z-shaped structure, one end of the first connection plate 1 and the outer plate 201 of the side panel 200 are fixedly connected through the first welding portion 2, the other end of the first connection plate 1 and the roof 100 are fixedly connected through the second welding portion 3, the second connection plate 4 is connected to the first connection plate 1, and the outer plate 201 of the side panel 200, the inner plate 202 of the side panel 200 and the second connection plate 4 are fixedly connected through the third welding portion 5.

[0039] The first welding portion 2, the second welding portion 3 and the third welding portion 5 are all welding edges, wherein the first welding portion 2 is the welding edge of the outer plate 201 of the side enclosure 200 and the Z-shaped first connecting plate 1, the second welding portion 3 is the welding edge of the top cover 100 and the Z-shaped first connecting plate 1, and the third welding portion 5 is the welding edge of the side enclosure 200 assembly and the second connecting plate 4. The welding sequence between the top cover 100 and the side enclosure 200 is as follows: first, the outer plate 201 of the side enclosure 200 and the first connecting plate 1 are welded through the first welding portion 2 to form the outer plate 201 assembly of the side enclosure 200, secondly, the outer plate 201 assembly of the side enclosure 200 and the inner plate 202 of the side enclosure 200 are welded through the third welding portion 5 to form the side enclosure 200 assembly, and finally, the side enclosure 200 assembly and the top cover 100 are welded through the second welding portion 3 to complete the welding connection between the top cover 100 and the side enclosure 200. The laser-MAG composite welding process is used to form a continuous fish scale weld at the bend, and the weld penetration reaches 70%-85% of the plate thickness, which increases the connection stiffness by 40% compared with the traditional spot welding process. The side panel 200 assembly of the flat-top body-in-white is kept unchanged, and a Z-shaped welding connecting plate structure is used in the middle position between the top cover 100 and the side panel 200 assembly to connect the side panel 200 and the top cover 100 assembly. After welding, the Y-direction boundary of the top cover 100 is equivalent to the Y-direction boundary of the side panel 200. While increasing the strength of the body-in-white, the position of the welding edge is closer to the outside of the body than the flat-top model, maximizing the internal space of the high-top cab body-in-white. At the same time, the commonality of the side panel 200 assembly is improved, and the cost is low.

[0040] Further, continue to refer to Figure 1-Figure 2The first connecting plate 1 includes a first connecting portion 11, an intermediate connecting portion 12 and a second connecting portion 13. The intermediate connecting portion 12 is connected between the first connecting portion 11 and the second connecting portion 13. The first connecting portion 11 is welded to the outer plate 201 of the side panel 200 through the first welding portion 2, and the second connecting portion 13 is welded to the top cover 100 through the second welding portion 3. The first connecting portion 11 and the second connecting portion 13 are both arranged perpendicular to the intermediate connecting portion 12 to form a Z-shaped structure, so that the first connecting portion 11 and the second connecting portion 13 can support the outer plate 201 of the side panel 200 and the top cover 100 respectively. The outer plate 201 of the side panel 200 and the first connecting portion 11 are welded through the first welding portion 2 to form the outer plate 201 assembly of the side panel 200, and the top cover 100 and the second connecting portion 13 are welded through the second welding portion 3. A Z-shaped welded connecting plate structure is used in the middle position of the top cover 100 and the side panel 200 assembly to maximize the internal space of the high-top cab body-in-white. Optionally, the bending angles of the first connecting portion 11, the second connecting portion 13 and the middle connecting portion 12 are controlled between 105 and 135 degrees to achieve optimization of the mechanical transfer path, thereby satisfying the collision energy absorption index required by the strength of the automobile side panel 200 and reducing the joint surface between the longitudinal beam of the top cover 100 and the pillar of the side panel 200 to a certain extent.

[0041] Further, continue to refer to Figure 1-Figure 2 The second connecting plate 4 is connected to the first connecting portion 11 and has a Z-shaped structure. The second connecting plate 4 includes a third connecting portion 41 and a fourth connecting portion 42. The third connecting portion 41 is connected between the first connecting portion 11 and the fourth connecting portion 42. The third connecting portion 41 and the fourth connecting portion 42 are arranged at an obtuse angle. The fourth connecting portion 42 is welded to the side enclosure 200 through a third welding portion 5. The side enclosure 200 and the fourth connecting portion 42 of the second connecting plate 4 are welded through the third welding portion 5 to form a side enclosure 200 assembly. A double Z-shaped welded connecting plate structure is used in the middle position between the top cover 100 and the side enclosure 200 assembly to replace a welding edge of a flat-top vehicle. While increasing the strength of the body-in-white, the position of the welding edge is closer to the outside of the vehicle body relative to the flat-top vehicle body, maximizing the internal space of the high-top cab body-in-white.

[0042] Preferably, the first connecting plate 1 and the second connecting plate 4 are integrally formed by stamping or the like, and have high structural strength and long service life.

[0043] This embodiment also provides a vehicle, including a cab and the above-mentioned commercial vehicle cab roof connection structure, wherein the cab includes a roof 100 and a side panel 200, and the commercial vehicle cab roof connection structure is connected between the roof 100 and the side panel 200. A Z-shaped welded connecting plate structure is used in the middle of the assembly of the roof 100 and the side panel 200, which increases the strength of the body-in-white and the position of the welding edge is closer to the outside of the body relative to the flat-top vehicle, thereby maximizing the internal space of the high-top cab.
