DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] See also Figures 1 to 6 The embodiment of the present application provides a top cover assembly and a vehicle thereof, which can solve the problem in the related art that when making the top cover, different molds need to be used to make top cover parts of different sizes. This solution has certain waste of molds and insufficient modularity.

[0028] The existing commercial vehicle standard roof uses a ring beam mode to support the roof system. The roof supports the roof assembly upward through the left and right bracket beams and the left and right inner upper cross beams. Depending on the width of the roof, roof cross beams of different lengths are required. Therefore, when making the roof, different molds are needed to make roof parts of different sizes. This solution has a certain waste of molds and insufficient modularity.

[0029] When making the top cover, different molds need to be used to make top cover parts of different sizes. This solution has certain waste of molds and insufficient modularization. On the first aspect, the embodiment of the present application provides a top cover assembly, which includes: an upper cross beam 1 inside the side enclosure and a top cover beam assembly 2, wherein the top cover beam assembly 2 is connected to the upper cross beam 1 inside the side enclosure, and the relative distance between the two sides of the top cover beam assembly 2 is adjustable; wherein, a first mounting structure for connecting the top cover beam assembly 2 is provided on the upper cross beam 1 inside the side enclosure, and a plurality of first mounting points are provided on the first mounting structure along the length extension direction of the upper cross beam 1 inside the side enclosure, and when the top cover beam assembly 2 is fixed to the upper cross beam 1 inside the side enclosure, the top cover beam assembly 2 is located at one of the first mounting points of the first mounting structure.

[0030] In the existing scheme, the front and rear brackets on the left and right sides of the top cover and the upper cross beam 1 inside the side enclosure are used as supports. The upper cross beam 1 inside the side enclosure extends upward and supports the top cover assembly together with the bracket. The parts in this way cannot be used interchangeably. The top covers of cabs of different widths and lengths need to be re-molded during production, which results in high investment costs. In the present application, although the parts are designed in a modular way so that the same size of molds can be used when the parts are produced, the relative distance between the two sides of the top cover beam assembly 2 is adjusted to meet the needs of different top cover assemblies for top cover beam assemblies 2 of different widths, and the position of the top cover beam assembly 2 on the upper cross beam 1 inside the side enclosure can be adjusted to meet the needs of different vehicle body lengths for the top cover assembly, so the size of the top cover assembly can be adjusted as needed. Therefore, in the present application, the top cover assemblies of cabs of different widths and lengths do not need to be re-molded during production, saving costs.

[0031] The side inner upper cross beam 1 is arranged along the length direction of the vehicle body, and the roof beam assembly 2 is arranged along the width direction of the vehicle body. The roof beam assembly 2 is arranged between the two side inner upper cross beams 1.

[0032] Specifically, the roof beam assembly 2 includes: a roof cross beam 21 and a bracket structure 20. The bracket structure 20 is arranged on both sides of the roof cross beam 21, and is connected to the inner upper cross beam 1 of the side enclosure through a first mounting structure, and the relative distance between the two bracket structures 20 is adjustable. That is, in one roof beam assembly 2, one roof cross beam 21 and two bracket structures 20 are arranged, and one roof cross beam 21 is arranged between two bracket structures 20.

[0033] Before the roof assembly is completed, the distance between the two bracket structures 20 can be adjusted as needed, that is, the position of the bracket structure 20 on the roof cross beam 21 can be adjusted. After the position of the bracket structure 20 is determined, the bracket structure 20 and the roof cross beam 21 are limited and fixed.

[0034] In this embodiment, a first overlap surface is provided on both sides of the roof cross beam 21, and a second overlap surface is provided at one end of the bracket structure 20, and the first overlap surface is overlapped and fixed with the second overlap surface. It should be noted that, in this embodiment, there is no limitation on whether the first overlap surface is at the top of the second overlap surface or the second overlap surface is at the top of the first overlap surface. The first overlap surface and the second overlap surface here refer to the portion of the roof cross beam 21 that can be fitted and connected with the bracket structure 20 and the portion of the bracket structure 20 that can be fitted and connected with the roof cross beam 21.

[0035] In actual operation, it does not mean that the first overlap surface as a whole must be overlapped and fixed with the second overlap surface as a whole, but that when the first overlap surface and the second overlap surface are overlapped, the area of ​​the overlapping part of the first overlap surface and the second overlap surface is less than or equal to the area of ​​the first overlap surface and the area of ​​the second overlap surface.

[0036] There are many ways to fix the first lap joint and the second lap joint. Based on the above embodiments, in this embodiment, a first threaded hole is opened on the first lap joint, and a second threaded hole is opened on the second lap joint, and the position of the first threaded hole corresponds to the position of the second threaded hole.

[0037] In this embodiment, the position of the first threaded hole corresponds to the position of the second threaded hole in that when the first overlapping surface overlaps the second overlapping surface, by adjusting the position of the bracket structure 20 or the top cover beam 21, some first threaded holes on the top cover beam 21 can be made coaxial with some second threaded holes on the bracket structure 20, so that the bracket structure 20 and the top cover beam 21 can be fixed by bolting the coaxial first threaded holes and the second threaded holes.

[0038] Therefore, in this embodiment, the width of the roof cross beam 21 assembly is adjusted by adjusting the area of ​​the overlapping portion between the bracket structure 20 and the roof cross beam 21. By adding a first threaded hole and a second threaded hole to the bracket structure 20 and the roof cross beam 21, the overlap length is positioned at different positions, and the overlap length is adjusted to meet the requirements of roof cross beam 21 assemblies of different widths.

[0039] Furthermore, in this embodiment, the bracket structure 20 and the top cover beam 21 are both configured as structures with a recessed middle portion, the first threaded hole is disposed in the recessed middle portion of the top cover beam 21 , and the second threaded hole is disposed in the recessed middle portion of the bracket structure 20 .

[0040] In addition to fixing the bracket structure 20 and the top cover cross beam 21 by bolts, the bracket structure 20 and the top cover cross beam 21 can also be fixed by welding the first overlap surface and the second overlap surface. In actual operation, different fixing methods can be selected according to actual conditions.

[0041] On the basis of the above embodiments, in this embodiment, the bracket structure 20 is connected to the inner upper cross beam 1 of the side enclosure. The first mounting structure includes a through hole 10 opened on one side of the inner upper cross beam 1 of the side enclosure, the through hole 10 is an oblong hole, and the length extension direction of the oblong hole is the same as the length extension direction of the inner upper cross beam 1 of the side enclosure; a positioning plate is provided at the end of the roof beam assembly 2, a positioning hole is provided on the positioning plate, the position of the positioning hole corresponds to the position of the through hole 10, the positioning plate is fixed to the inner upper cross beam 1 of the side enclosure by a first stopper 11, and the positioning hole is used for the first stopper 11 to pass through.

[0042] See also Figure 5 As shown, when the bracket structure 20 is placed on the inner upper cross beam 1 of the side enclosure, the positioning plate covers the position of the oblong hole, and the positioning hole on the positioning plate is coaxial with the middle of the oblong hole. In this embodiment, the first stopper 11 is a bolt, and the bracket structure 20 can be fixed to the inner upper cross beam 1 of the side enclosure by passing the bolt through the positioning hole and the oblong hole.

[0043] Generally, a plurality of roof beam assemblies 2 are arranged on the upper inner cross beam 1 of the side wall, that is, when the positioning plate moves at the oblong hole on the upper inner cross beam 1 of the side wall, the distance between two adjacent roof beam assemblies 2 can be adjusted. For cabs of different lengths, the adjustment of the distance between the roof beam assemblies 2 can adjust the overall rigidity of the roof assembly to ensure that there is no local rigidity failure. At the same time, for cabs of different lengths, the adjustable distance between the roof beam assemblies 2 also has a good effect on improving the overall mode of the roof assembly.

[0044] On the basis of the above embodiment, in order to improve the connection strength between the bracket structure 20 and the upper inner cross beam 1 of the side enclosure, a hinge structure 22 is provided on the roof beam assembly 2, and one end of the hinge structure 22 is fixed to the upper inner cross beam 1 of the side enclosure.

[0045] Among them, the purpose of setting the hinge structure 22 is that when the bracket structure 20 of the roof beam assembly 2 moves forward and backward, since the overlapping edge of the upper cross beam 1 inside the side panel is not in a straight state, the upper cross beam 1 inside the side panel and the bracket structure 20 can be kept in a fit state through the set hinge mechanism, and are connected by welding and bolts after the position adjustment is completed.

[0046] Specifically, the hinge structure 22 includes a first connecting plate and a second connecting plate, wherein the first connecting plate is fixed to the bracket structure 20 in the roof beam assembly 2, and the second connecting plate is fixed to the inner upper cross beam 1 of the side enclosure, and the first connecting plate and the second connecting plate are hinged. Therefore, when the bracket structure 20 moves forward and backward on the inner upper cross beam 1 of the side enclosure, since the overlapping edge of the inner upper cross beam 1 of the side enclosure is not in a straight state, the angle between the first connecting plate and the second connecting plate will also change accordingly. After determining the installation position of the bracket structure 20, the second connecting plate is welded or threaded to the inner upper cross beam 1 of the side enclosure.

[0047] In addition to adjusting the spacing of the roof beam assembly 2 on the upper cross beam 1 inside the side panel in the manner described above, for cabs of different lengths, the length of the upper cross beam 1 inside the side panel is also different, and the performance requirements of different cabs can be changed by increasing or decreasing the number of roof beam assemblies 2: for a shorter cab, two roof beam assemblies 2 can be used; for a longer cab, the entire roof assembly can be set to include at least three roof beam assemblies 2.

[0048] In addition to adjusting the spacing of the top cover beam assembly 2 on the side inner upper cross beam 1, the relative distance between the two ends of the side inner upper cross beam 1 can also be adjusted, that is, the side inner upper cross beam 1 is divided into two parts, and the connection of the two parts can overlap. The more the two parts overlap, the shorter the relative distance between the two ends of the side inner upper cross beam 1 is, and the less the two parts overlap, the longer the relative distance between the two ends of the side inner upper cross beam 1 is. In this way, the side inner upper cross beam 1 can be adapted to cabs of different lengths. The overlapping area of ​​the two parts can be fixed by bolting or welding.

[0049] On the basis of the above embodiments, in this embodiment, when a plurality of roof beam assemblies 2 are arranged on the inner upper cross beam 1 of the side enclosure, a reinforcing beam assembly 3 is arranged between two adjacent roof beam assemblies 2 .

[0050] The reinforcing beam assembly 3 is a supplementary part for improving the overall performance of the top cover assembly. Since there are different mounting parts on the top cover assembly, in order to meet the needs of different mounting parts, the top cover assembly needs to be specially reinforced locally. At the same time, adding the reinforcing beam assembly 3 between the top cover beam assemblies 2 can improve the problem of insufficient local rigidity between the top cover beam assemblies 2. In addition, the addition of the reinforcing beam assembly 3 also provides an installation point for the installation of the interior of the top cover assembly.

[0051] Furthermore, a second mounting structure for connecting the reinforcing beam assembly 3 is provided on the roof beam assembly 2, and the second mounting structure has a plurality of second mounting points. When the roof beam assembly 2 and the reinforcing beam assembly 3 are fixed, the reinforcing beam assembly 3 is located at one of the second mounting points of the second mounting structure.

[0052] The reinforcing beam assembly 3 includes: a reinforcing cross beam 30 and a reinforcing longitudinal beam 31 . The reinforcing longitudinal beams 31 are arranged on both sides of the reinforcing cross beam 30 , and the reinforcing longitudinal beams 31 are connected to the roof beam assembly 2 via a second mounting structure.

[0053] That is to say, a second mounting structure is provided on the roof cross beam 21 of the roof beam assembly 2. Figure 6 As shown, it can be a mounting groove 210 opened on the roof cross beam 21, and the mounting groove 210 is set along the length extension direction of the roof cross beam 21. The reinforcing longitudinal beam 31 moves at the mounting groove 210, and after the positions of two adjacent reinforcing longitudinal beams 31 are determined, the reinforcing longitudinal beam 31 is connected to the roof cross beam 21 through the second stopper 211. In this embodiment, the second stopper 211 can be a bolt, and a threaded hole is opened at the end of the reinforcing longitudinal beam 31, so that the bolt can pass through the threaded hole and the mounting groove 210 to connect and fix the reinforcing longitudinal beam 31 to the roof cross beam 21.

[0054] The reinforcing crossbeam 30 is divided into two parts, and the connection of the two parts can overlap. The more the two parts overlap, the shorter the relative distance between the two ends of the reinforcing crossbeam 30 is, and the less the two parts overlap, the longer the relative distance between the two ends of the reinforcing crossbeam 30 is. In this way, the reinforcing crossbeam 30 can be adapted to reinforcing beam assemblies 3 of different widths. The overlapping area of ​​the two parts can be fixed by bolts or welding to ensure the rigidity and modality of the entire top cover assembly.

[0055] For different mounting parts on the top cover assembly, the width adjustment of the reinforcing beam assembly 3 can meet different installation needs. Taking the roof-mounted air conditioner as an example, when installing the roof-mounted parking air conditioner, the reinforcing cross beam 30 of the reinforcing beam assembly 3 can be cancelled. By adjusting the width of the spacing between the other two reinforcing longitudinal beams 31, the installation needs of air conditioners of different sizes can be met to provide support for the top mounting parts.

[0056] In summary, the roof beam assembly 2 in the present application is a new module design. Since there are cabs of different lengths with the same width, different lengths of the inner upper cross beams 1 of the side enclosure are required to meet their performance requirements. Therefore, the distance between two adjacent roof beam assemblies 2 can be adjusted by the oblong holes and bolts of the inner upper cross beam 1 of the side enclosure. In the roof assemblies of different vehicle widths, the lap width of the roof beam 21 and the bracket structure 20 in the roof beam assembly 2 can be adjusted to obtain roof beam assemblies 21 of different widths. A modular parts design is adopted, and the requirements of different roof assemblies for roof beam assemblies 2 of different widths are met by adjusting the lap edges of the connection area. At the same time, the roof beam assembly 2 is adjusted to move forward and backward on the inner upper cross beam 1 of the side enclosure to meet the requirements of the roof assembly for different vehicle body lengths.

[0057] The new roof crossbeam 21 assembly ensures the commonality of other assemblies of the cab except the roof assembly. Taking the side panel assembly as an example, for roof panels of different heights, the side panels do not need to change the structure of the inner upper crossbeam, but can meet the requirements of different vehicle heights by adjusting the heights of the left and right bracket structures 20. When adjusting, it is only necessary to replace the bracket structures 20 of different heights to connect them with the inner upper crossbeam 1 of the side panel and the roof crossbeam 21.

[0058] By adjusting the distance between the roof beam assemblies 2, the local rigidity and modal condition of the roof assembly can be adjusted to ensure the consistency of the overall performance of the roof. At the same time, when installing different mounting parts, the overall rigidity and modal performance of the roof assembly can be improved by adding a width-adjustable reinforcing beam assembly 3 between the roof beam assemblies 2. The width of the roof beam assembly 2 can be adjusted according to the width of the vehicle body. At the same time, the internal reinforcing beam assembly 3 can also adjust the distance between the reinforcing longitudinal beams 31 by adjusting the tightness of the bolts and then moving them to meet the different size requirements between different mounting parts. The reinforcing beam assembly 3 can improve the local rigidity of the entire roof, and at the same time improve the problem of "drumming" on the top of the cab mode due to the large distance between the roof beam assemblies 2.

[0059] Compared with the traditional assembly, the top cover assembly supported by the top cover beam assembly 2 does not require the upper cross beam 1 inside the side panel to overlap with the top cover assembly, and the mass of the upper cross beam 1 inside the side panel is reduced. With the same performance, the mass is lighter.

[0060] In a second aspect, an embodiment of the present application provides a car, which includes a top cover assembly provided by any of the above embodiments of the present application.

[0061] In the existing scheme, the front and rear brackets on the left and right sides of the top cover and the upper cross beam 1 inside the side enclosure are used as supports. The upper cross beam 1 inside the side enclosure extends upward and supports the top cover assembly together with the bracket. The parts in this way cannot be used interchangeably. The top covers of cabs of different widths and lengths need to be re-molded during production, which results in high investment costs. In the present application, although the parts are designed in a modular way so that the same size of molds can be used when the parts are produced, the relative distance between the two sides of the top cover beam assembly 2 is adjusted to meet the needs of different top cover assemblies for top cover beam assemblies 2 of different widths, and the position of the top cover beam assembly 2 on the upper cross beam 1 inside the side enclosure can be adjusted to meet the needs of different vehicle body lengths for the top cover assembly, so the size of the top cover assembly can be adjusted as needed. Therefore, in the present application, the top cover assemblies of cabs of different widths and lengths do not need to be re-molded during production, saving costs.

[0062] The roof beam assembly 2 in the present application is a new module design. Since there are cabs of different lengths with the same width, different lengths of the inner upper cross beams 1 of the side enclosure are required to meet their performance requirements. Therefore, the distance between two adjacent roof beam assemblies 2 can be adjusted by the oblong holes and bolts of the inner upper cross beam 1 of the side enclosure. In the roof assemblies of different vehicle widths, the lap width of the roof beam 21 and the bracket structure 20 in the roof beam assembly 2 can be adjusted to obtain roof beam assemblies 21 of different widths. A modular parts design is adopted, and the requirements of different roof assemblies for roof beam assemblies 2 of different widths are met by adjusting the lap edges of the connection area. At the same time, the roof beam assembly 2 is adjusted to move forward and backward on the inner upper cross beam 1 of the side enclosure to meet the requirements of the roof assembly for different vehicle body lengths.

[0063] The new roof crossbeam 21 assembly ensures the commonality of other assemblies of the cab except the roof assembly. Taking the side panel assembly as an example, for roof panels of different heights, the side panels do not need to change the structure of the inner upper crossbeam, but can meet the requirements of different vehicle heights by adjusting the heights of the left and right bracket structures 20. When adjusting, it is only necessary to replace the bracket structures 20 of different heights to connect them with the inner upper crossbeam 1 of the side panel and the roof crossbeam 21.

[0064] By adjusting the distance between the roof beam assemblies 2, the local rigidity and modal condition of the roof assembly can be adjusted to ensure the consistency of the overall performance of the roof. At the same time, when installing different mounting parts, the overall rigidity and modal performance of the roof assembly can be improved by adding a width-adjustable reinforcing beam assembly 3 between the roof beam assemblies 2. The width of the roof beam assembly 2 can be adjusted according to the width of the vehicle body. At the same time, the internal reinforcing beam assembly 3 can also adjust the distance between the reinforcing longitudinal beams 31 by adjusting the tightness of the bolts and then moving them to meet the different size requirements between different mounting parts. The reinforcing beam assembly 3 can improve the local rigidity of the entire roof, and at the same time improve the problem of "drumming" on the top of the cab mode due to the large distance between the roof beam assemblies 2.

[0065] Compared with the traditional assembly, the top cover assembly supported by the top cover beam assembly 2 does not require the upper cross beam 1 inside the side panel to overlap with the top cover assembly, and the mass of the upper cross beam 1 inside the side panel is reduced. With the same performance, the mass is lighter.
