[0001] This invention relates to the field of automotive interior technology, and in particular to a structure and method for the roof interior of the driver's area in a passenger vehicle. Background Technology

[0002] The headliner in the driver's area is an important part of the vehicle's interior, playing a vital role in enhancing driving and riding comfort. It is also a key interior component that integrates and houses the vehicle's electrical control modules.

[0003] The inventors discovered that, under normal circumstances, the interior trim of the driver's area of ​​a city bus is simply assembled from multiple parts. When installing the interior trim, the existing installation method is to install the trim pieces one by one on the top of the driver's area. Due to the limited space in the driver's area and the complex structure of the interior trim, this method of installing the trim pieces one by one on the top of the driver's area has the problems of long working time at high positions and installation difficulties. In addition, some interior trim pieces are directly connected to the fixing plates on the vehicle body through fasteners, resulting in exposed mounting points for the interior trim in the driver's area, which leads to defects in the refinement and texture. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a structure and method for the roof interior of a bus driver's area, which can connect the front roof interior, front door upper roof interior, second middle roof interior, first middle roof interior, driver's upper roof interior, and bridge interior into a single structure at a low position. This reduces the labor intensity of construction workers and avoids the safety hazards of high-level operations. At the same time, the fixing points can be hidden when the overall structure is assembled in the driver's area.

The bottom of the third irregular bracket is welded to the top surface of the flange of the first top interior trim. The top of the second top interior trim is welded to the bottom surface of the flange of the first top interior trim via a Z-shaped bracket. The flange of the first top interior trim and the third irregular bracket are provided with through holes, which are coaxially arranged with the spotlight mounting holes on the second top interior trim. Bolts pass through the spotlight mounting holes and through the through holes to achieve threaded connection with the body fixing plate.

[0009] As a further implementation, a connecting beam is provided at the top of the front side of the overpass interior trim. The left end of the connecting beam is welded and fixed to the vertical plate, and the rear end of the flange of the first top interior trim is welded to the right end of the connecting beam.

[0010] As a further implementation, the first irregular bracket is Z-shaped and includes a top plate, a side plate and a bottom plate connected in sequence. The right side of the first top interior trim is fixed to the left side of the driver's top interior trim by a flange. The top of the flange is welded to the bottom plate, and the front end of the first irregular bracket is welded to the bridge interior trim.

[0011] As a further implementation, the bottom surface of the front roof interior is provided with a front roof interior bottom inspection door, the rear side is provided with a front roof interior vertical inspection door, the top of the front side of the bottom surface of the front roof interior is provided with a front roof interior fixing angle steel, the front roof interior fixing angle steel is located in front of the front roof interior bottom inspection door, and the top of the front front of the front roof interior is provided with an L-shaped connecting plate. By opening the corresponding inspection door, the L-shaped connecting plate and the front roof interior fixing angle steel can be hiddenly connected to the corresponding body fixing plate.

[0012] As a further implementation, the bridge interior is U-shaped, with a front access door on the front side and a rear access door on the rear side. The top of the rear side has a bridge interior flange. By opening the corresponding access door, the connecting beam and the bridge interior flange can be hiddenly connected to the corresponding vehicle body fixing plate.

[0013] As a further implementation, the upper interior trim of the front door is provided with an inspection port, and the left side is provided with a front interior trim panel flap; the right side of the driver's upper interior trim is provided with a driver's upper interior trim panel flap, and the left side is provided with a driver's upper interior trim panel inspection door. By opening the inspection port or inspection door, the corresponding irregular bracket can be connected to the vehicle body fixing plate; the corresponding flap is bonded to the corresponding vehicle body fixing plate.

[0014] Secondly, a method for installing a driver's area roof interior structure for a passenger vehicle, using any of the above-described driver's area roof interior structures, includes the following steps: The first irregular bracket connects the front roof interior, driver's upper roof interior, and first middle roof interior. The third irregular bracket connects the first middle roof interior, second middle roof interior, and bridge interior. The second irregular bracket connects the second middle roof interior, front door upper roof interior, and bridge interior, thus achieving a low-level connection between the three sets of irregular brackets and six sets of interior parts into a whole. Opening the inspection door corresponding to the front roof interior allows for a concealed connection between the L-shaped connecting plate and the front roof interior fixing angle steel and the corresponding body fixing plate. Opening the inspection door corresponding to the bridge interior allows for a concealed connection between the connecting beam and the bridge interior flange and the corresponding body fixing plate. Opening the front door upper roof interior inspection port reveals a front door upper roof interior flange on the left side. Opening the driver's upper roof interior inspection door allows for the connection of the corresponding irregular bracket to the body fixing plate via the inspection port or door. The corresponding flange is then bonded to the corresponding body fixing plate.

[0015] The beneficial effects of the present invention are as follows: This embodiment utilizes three sets of irregularly shaped brackets to connect the front roof interior, front door roof interior, second roof center interior, first roof center interior, driver's roof interior, and bridge interior into a single unit at a low position. This reduces the labor intensity of construction workers and avoids the safety hazards of high-level operations. After the six interior components are connected as a whole at a low position using the irregularly shaped brackets, they can be assembled as a whole, realizing the integrated installation of the complex driver's area roof interior. This improves the cycle efficiency of the assembly line and reduces the time spent on high-level installation.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a driver's area roof interior structure for a passenger vehicle is divided into six parts according to its position and function: front interior parts, middle interior parts, and rear interior parts, from front to back. The front interior parts are the front roof interior parts 1. The middle interior parts include four sets of interior parts, which, viewed from back to front, are, from left to right, the front door upper roof interior parts 5, the second middle roof interior parts 4, the first middle roof interior parts 3, and the driver's upper roof interior parts 2. The rear interior parts are the bridge interior parts 6. All six sets of interior parts are individually manufactured using a foam molding process.

[0022] like Figure 1 As shown, the back of the six interior trim pieces is connected into an integrated structure by three sets of irregularly shaped brackets. The three sets of irregularly shaped brackets are the first irregularly shaped bracket 100, the second irregularly shaped bracket 200, and the third irregularly shaped bracket 300.

[0023] like Figure 2As shown, the second irregular bracket 200 is Z-shaped and includes a flat plate 201, a vertical plate 202, and an inclined plate 203 connected in sequence, wherein the inclined plate 203 is inclined relative to the vertical plate. The second irregular bracket 200 is used to fix the front door upper top interior trim 5, the second top middle interior trim 4, and the bridge interior trim 6.

[0024] Looking from the rear of the vehicle to the front, the interior trim of the driver's area of ​​the bus, from left to right, consists of the front door upper interior trim 5, the second middle interior trim 4, the first middle interior trim 3, and the driver's upper interior trim 2. The second middle interior trim 4 and the front door upper interior trim 5 overlap each other on one side. The vertical plate of the second irregular bracket 200 is fixedly connected to the top of the front door upper interior trim 5 by a fastener 53, and the bottom surface of the inclined plate is fixedly connected to the top of the second middle interior trim 4.

[0025] Specifically, the side (left side) of the second upper interior trim 4 near the front door upper interior trim 5 is joined to the side (right side) of the front door upper interior trim 5 near the second upper interior trim 4 via a stepped structure formed by a flange. The bottom of the inclined plate 203 is welded to the top of the left side of the second upper interior trim 4. The top of the front door upper interior trim 5 has three connection points, and the vertical plate 202 has corresponding fixing holes. The three connection points and the three sets of fixing holes are fixedly connected by connectors 53. The two ends of the connectors are set as plate structures with through holes to facilitate docking and fixing with the vertical plate 202 and the connection points.

[0026] Understandably, the connection point of the upper interior trim surface of the front door is a raised structure of a predetermined thickness, with threaded holes on the raised structure, which is fixed to the connector 53 by bolts. The threaded holes do not penetrate the upper interior trim surface 5 of the front door, ensuring that the fixing point is not exposed. The connector 53 can specifically be a bent plate with through holes, the bending angle determined by the relative position of the vertical plate and the raised structure.

[0027] The front side of the bridge interior trim 6 engages with the rear side of the front door upper roof interior trim 5 and the second roof center interior trim 4. A connecting beam 64 is provided at the front side of the bridge interior trim 6, and the left end of the connecting beam 64 is welded and fixed to the vertical plate 202. The second irregular bracket 200 connects the second roof center interior trim 4, the front door upper roof interior trim 5, and the bridge interior trim 6 into one unit.

[0028] like Figure 4 As shown, the third irregular bracket 300 is a plate-like structure that is inclined relative to the length direction of the vehicle body and is used to fix it to the second top interior trim 4 and the first top interior trim 3.

[0029] Specifically, the extension direction of the left side of the first interior trim 3 and the right side of the second interior trim 4 is in the same direction as the length direction of the third irregular bracket 300. The left side of the first interior trim 3 is provided with an upward flange 31, which overlaps the right side of the second interior trim 4. The bottom of the third irregular bracket 300 is welded to the top surface of the flange of the first interior trim 3. The top of the second interior trim 4 is welded to the bottom surface of the flange 31 of the first interior trim 3 through two sets of Z-shaped brackets 41. This achieves the fixation of the joint between the first interior trim 3 and the second interior trim 4, and at the same time, it is fixedly connected to the third irregular bracket 300.

[0030] In this embodiment, the first and second interior trim panels 3 and 4 are connected into a single structure via the third irregularly shaped bracket 300. It is understood that the rear end of the flange of the first interior trim panel 3 is also welded to the right end of the connecting beam 64 on the bridge trim panel 6, achieving a relatively fixed connection between the bridge trim panel 6 and the first interior trim panel 3.

[0031] In this embodiment, the first top center interior trim 3, the second top center interior trim 4, the front door top interior trim 5, and the bridge interior trim 6 are fixedly connected as one unit through the second irregular bracket 200 and the third irregular bracket 300.

[0032] like Figure 5 As shown, the first irregular bracket 100 is Z-shaped and includes a top plate 101, a side plate 102 and a bottom plate 103 connected from top to bottom. The right side of the first top interior trim 3 is provided with a flange 32. The top surface of the flange 32 is welded to the bottom surface of the bottom plate, and the bottom surface of the flange 32 is welded to the left side of the driver's top interior trim 2.

[0033] like Figure 6 As shown, a set of fixing plates 104 are vertically installed at the front end of the base plate of the first irregular bracket 100. The rear side of the front roof interior 1 is respectively connected to the front side of the front door upper roof interior 5, the second middle roof interior 4, the first middle roof interior 3, and the driver's upper roof interior 2 by means of flanges 15. The front roof interior 1 is provided with a connecting plate 14 at the position corresponding to the fixing plate 104 of the first irregular bracket, and is fixed to the fixing plate 104 by welding the connecting plate 14.

[0034] The front roof interior 1, the driver's upper roof interior 2, and the first middle roof interior 3 are fixed into an integral structure by the first irregular bracket 100.

[0035] like Figure 10 As shown, the top front side of the second interior trim 4 is also connected to the left end of the flange 15 of the front interior trim via a U-shaped bracket 41. The U-shaped bracket 41 is coaxially arranged with the spotlight mounting hole 42.

[0036] The front roof interior 1, driver's roof interior 2, first roof center interior 3, first roof center interior 4, front door roof interior 5, and bridge interior 6 are fixed together by the first irregular bracket 100, the second irregular bracket 200, and the third irregular bracket 300. Thus, a total of nine structural components are fixed together, and the driver's area roof interior, which is completed by low-level operation, can be installed as a whole.

[0037] The front roof interior 1 is also equipped with multiple sets of L-shaped connecting plates 16 at the top front end, which are fixedly connected to the seventh body fixing plate 70 through the L-shaped connecting plates 16.

[0038] like Figure 9 As shown, the left side of the front door upper top interior trim 5 is provided with a front door upper top interior trim flap 51; the middle position of the front door upper top interior trim 5 is provided with a front door upper top interior trim inspection port 52.

[0039] like Figure 10 As shown, the flange 51 of the upper interior trim panel of the front door is glued to the first body fixing plate 10, thus concealing the fixing point. Then, the inspection port 52 of the upper interior trim panel of the front door is opened, and the flat plate 201 of the second irregular bracket 200 is fixedly connected to the second body fixing plate 20, thus concealing the fixing point.

[0040] like Figure 4 As shown, a spotlight mounting hole 42 is provided on the right side of the second interior trim 4 corresponding to the position of the U-shaped bracket. The U-shaped bracket 41, the flange on the left side of the first interior trim, and the third irregular bracket 300 are coaxially provided with through holes at the positions corresponding to the spotlight mounting holes. The bolt passes through the spotlight mounting hole and through the through hole to achieve threaded connection with the third body fixing plate 30, thereby hiding the fixing point and pressing the U-shaped bracket with the bolt.

[0041] like Figure 5 and Figure 10 As shown, the driver's upper interior trim 2 has a U-shaped cross-section. Its left side has a driver's upper interior trim access door 21. After opening the access door 21, bolts are passed through the top plate 101 of the first irregular bracket 100 and connected to the fourth body fixing plate 40, thus fixing the left side of the driver's upper interior trim 2 and concealing the fixing point. The top right side of the driver's upper interior trim 2 has a driver's upper interior trim flange 22, which is glued to the fifth body fixing plate 50 using adhesive, thus concealing the fixing point.

[0042] like Figure 7 and Figure 11As shown, a front roof interior panel inspection door 13 is provided on the rear side of the front roof interior panel 1. Opening the front roof interior panel inspection door 13 allows for fixed connection with the seventh body mounting plate 70 via an L-shaped connecting plate 16 on the front roof interior panel 1, thus concealing the fixing point. A front roof interior bottom inspection door 12 is provided at the bottom of the front roof interior panel, and a front roof interior fixing angle steel 11 is provided at the top of the front side of the front roof interior panel. The front roof interior fixing angle steel 11 is located in front of the front roof interior bottom inspection door 12. Opening the front roof interior bottom inspection door 12 allows for connection between the front roof interior fixing angle steel 11 and the sixth body mounting plate 60, thus concealing the fixing point.

[0043] like Figure 8 and Figure 11 As shown, the cross-section of the bridge interior trim 6 is also U-shaped. The front side of the bridge interior trim 6 has a front facade inspection door 61, and a connecting beam 64 is located at the top of the front side, which is higher than the front facade inspection door 61. The rear side of the bridge interior trim 6 has a rear facade inspection door 63, and a flange 62 is located at the top of the rear side, which is higher than the rear facade inspection door 63.

[0044] Opening the front access door 61 of the bridge interior allows the connecting beam 64 to be connected to the eighth body mounting plate 80, thus concealing the mounting point. Opening the rear access door 63 of the bridge interior allows the bridge interior flange 62 to be connected to the ninth body mounting plate 90, thus concealing the mounting point.

[0045] It is understood that in this embodiment, on all structures that are fixed in contact by bolts (where they are connected to different body panels), 2mm of damping cotton is bonded at the joint to prevent abnormal noise caused by body twisting during driving, which would affect the comfort of the driver and passengers.

[0046] This embodiment utilizes three sets of irregularly shaped brackets to connect the front roof interior 1, front door upper roof interior 5, second middle roof interior 4, first middle roof interior 3, driver's upper roof interior 2, and bridge interior 6 into a single unit at a low position. This reduces the labor intensity of construction workers and avoids the safety hazards of high-level operations. After the six sets of interior components are connected as a whole by the irregularly shaped brackets, they can be assembled as a whole, realizing the integrated installation of the complex driver's area roof interior and improving the cycle efficiency of the assembly line. During overall assembly, the fasteners are installed by opening different inspection doors and ports, concealing the fixing points of each component. Furthermore, the connection points between each component and the vehicle body frame are also concealed, making the driver's area more aesthetically pleasing and improving the overall appearance of the bus interior.

[0047] Example 2 A method for installing a driver's area roof interior structure for a passenger vehicle, used for installing the driver's area roof interior structure of Embodiment 1, includes the following steps: The front roof interior 1, driver's roof interior 2 and first roof center interior 3 are connected by the first irregular bracket 100. The first roof center interior 3, second roof center interior 4 and bridge interior 6 are connected by the third irregular bracket 300. The second roof center interior 4, front door roof interior 5 and bridge interior 6 are connected by the second irregular bracket 200.

[0048] Specifically, the top of the second interior trim 4 is welded to the bottom surface of the flange 31 of the first interior trim 3 via two sets of Z-shaped brackets 41, and the top surface of the flange 31 is welded to the third irregular bracket. At the same time, the overpass trim overlaps on the second interior trim, and the connecting beam is welded to the flange 31.

[0049] The right side of the upper front door interior trim overlaps with the left side of the middle second interior trim. Using a second irregularly shaped bracket and connectors, the upper front door interior trim and the middle second interior trim are connected respectively. The connecting beam is welded to the vertical plate of the second irregularly shaped bracket. The first irregularly shaped bracket is welded to the flange 32 of the first center interior trim, and the flange 32 is welded to the driver's upper interior trim. The front interior trim 1 is overlapped onto the middle interior trim via flange 15. The fixing plate 104 is welded to the connecting plate 14. A set of Z-shaped brackets 41 connects the left end of the flange 15 of the front interior trim. This achieves a low-level connection between three sets of irregularly shaped brackets and six sets of interior trim into a single structure.

[0050] The flange 51 of the upper interior trim panel on the front door is glued to the first body mounting plate 10, thus concealing the fixing point. Then, the inspection port 52 of the upper interior trim panel on the front door is opened, and the flat plate 201 of the second irregular bracket 200 is fixedly connected to the second body mounting plate 20, thus concealing the fixing point.

[0051] like Figure 4 As shown, a spotlight mounting hole 42 is provided on the right side of the second interior trim 4 corresponding to the position of the U-shaped bracket. The U-shaped bracket 41, the flange on the left side of the first interior trim, and the third irregular bracket 300 are coaxially provided with through holes at the positions corresponding to the spotlight mounting holes. The bolt passes through the spotlight mounting hole and through the through hole to achieve threaded connection with the third body fixing plate, thereby hiding the fixing point and pressing the U-shaped bracket with the bolt.

[0052] like Figure 5 and Figure 11 As shown, bolts are used to connect the top plate 101 of the first irregular bracket 100 to the fourth body fixing plate 40, thereby fixing the left side of the driver's upper roof interior 2 and concealing the fixing point. The driver's upper roof interior flange 22 is then glued to the fifth body fixing plate 50 with adhesive, thus concealing the fixing point.

[0053] like Figure 7 and Figure 12As shown, opening the front roof interior panel access door 13 allows for a secure connection between the L-shaped connecting plate 16 on the front roof interior panel 1 and the seventh body mounting plate 70, thus concealing the mounting point. Opening the bottom access door 12 of the front roof interior panel allows for the connection between the front roof interior panel fixing angle steel 11 and the sixth body mounting plate 60, further concealing the mounting point.

[0054] like Figure 8 and Figure 12 As shown, opening the front access door 61 of the bridge interior allows the connecting beam 64 to be connected to the eighth body mounting plate 80, thus concealing the mounting point. Opening the rear access door 63 allows the bridge interior flange 62 to be connected to the ninth body mounting plate 90, thus concealing the mounting point.

[0055] It is understandable that the structural components connected to the corresponding fixing points need to be provided with corresponding connection holes, such as the main body of the irregular bracket plate, the vehicle body fixing plate, etc.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
