Description

Technical Field

[0002] The interior trim of the commercial vehicle cab side panel mainly includes the upper side panel, the side storage box, the curtain rail trim panel, and other parts.

[0003] One existing positioning solution relies on the connection points between the upper side panel, the side storage box, and the body-in-white to achieve self-positioning of the parts. Fastening points are designed and arranged according to the principle of uniform distribution. The positioning accuracy of this positioning design basically relies on the dimensional accuracy of the interior parts themselves and the accuracy and manufacturing accuracy of the parts in the corresponding areas of the body.

[0004] However, because the positioning points of different parts are scattered across different vehicle body structural components, the dimensional chain ensuring aesthetic and functional requirements between interior parts and between interior parts and surrounding components is complex, with large tolerances in each link. This frequently leads to unsatisfactory actual vehicle matching results, numerous gaps and surface defects, and an inability to meet the continuous improvement requirements for overall vehicle aesthetics and perceived quality. Alternatively, it may only involve localized direct positioning and overlapping structures between specific interior parts, lacking universal applicability. Summary of the Invention

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] This application provides an interior trim panel assembly and a vehicle to address the problems in related technologies where the positioning points of different parts are dispersed on different vehicle body structural components. This results in numerous dimensional chains and links in ensuring the aesthetic function between interior parts and between interior parts and surrounding environmental components, large chain tolerances, frequent unsatisfactory actual vehicle matching effects, and various gap and surface differences, making it impossible to meet the needs of continuous improvement in the aesthetic characteristics and perceived quality of the entire vehicle.

[0047] It should be noted that: the following vehicle front-to-rear direction refers to the direction from the front to the rear of the vehicle; the vehicle left-to-right direction refers to the width of the vehicle; and the vehicle up-and-down direction refers to the direction from the chassis to the roof of the vehicle.

[0048] Please see Figures 1-12 A driver's interior trim panel assembly includes a side trim panel assembly 6, a rear interior trim panel 7, a curtain rail trim panel 9, and a side roof interior trim panel 10; it also includes a separately provided trim panel bracket, which includes a horizontal positioning portion 1 and a vertical positioning portion 2, and is integrally manufactured.

[0049] The horizontal positioning part 1 is arranged along the front-rear direction of the vehicle, and its vertical side in the left-right direction is the side panel sheet metal bonding surface; the two ends of the side panel sheet metal bonding surface in the front-rear direction of the vehicle are the rear beam connection end and the middle pillar inner panel connection end, respectively; the top of the horizontal positioning part 1 is provided with an upper crossbeam connection part 4.

[0050] The upper crossbeam connecting part 4 includes multiple connecting pieces spaced apart along the front-rear direction of the vehicle. The connecting pieces are provided with first mounting holes 400. The connecting pieces are connected to the upper crossbeam 8 by M8 bolts, which limit the movement in the front-rear direction of the vehicle. The rear beam connecting end and the middle pillar inner plate connecting end are both provided with threaded mounting holes. Since the first mounting hole 400 is above the threaded mounting hole and there is a gap between them, it can limit the movement in the vehicle height. In addition, due to the side panel sheet metal bonding surface and the side panel sheet metal, it is also positioned in the left-right direction of the vehicle after installation.

[0051] The vertical positioning part 2 is parallel to the vertical direction of the vehicle in its length direction and perpendicular to the side panel sheet metal bonding surface in its width direction. It forms a right angle structure with the horizontal positioning part 1 at the connection point and is not on the same plane. The upper part of one side of the vertical positioning part 2 in the width direction is connected to the rear beam connection end, and the lower part is provided with a rear beam connecting plate 5 parallel to the side panel sheet metal bonding surface. The surface of the vertical positioning part 2 in the front-rear direction of the vehicle is a connecting vertical surface. The trim panel bracket is connected to the side panel trim panel assembly 6 and the rear interior trim panel 7 through the connecting vertical surface.

[0052] Additionally, the rear beam connecting plate 5 has a connecting plane that fits against the rear beam 11; the rear beam connecting plate 5 has a second mounting hole 500, which facilitates connection with the rear beam 11; after the trim bracket is connected to the rear beam 11 and the inner plate 3 of the center pillar, the bottom of the vertical positioning part 2 is fixed to the middle of the rear beam 11, and the top of the horizontal positioning part 1 and the vertical positioning part 2 are connected. Since the position of the horizontal positioning part 1 is fixed, the vertical positioning part 2 is limited by the horizontal positioning part 1 and the rear beam 11 in the front-rear direction of the vehicle, and is also positioned in the vertical direction of the vehicle; furthermore, since the rear beam connecting plate 5 and the horizontal positioning part 1 are located on the same plane and cooperate to connect the vertical surface, a right-angle limiting structure is formed to connect with the rear beam 11, thereby limiting the vehicle in the left-right direction.

[0053] This design limits the trim panel bracket in the front-to-back, left-to-right, and up-to-down directions of the vehicle, and it has corresponding mounting holes, thus ensuring its installation accuracy after installation.

[0054] Since the trim panel bracket includes a horizontal positioning part 1 and a vertical positioning part 2, the horizontal positioning part 1 is connected to the rear beam 11 and the inner plate 3 of the middle pillar at both ends, and to the upper cross beam 8 at the top, and has a side panel sheet metal fitting surface, thus the horizontal positioning part 1 is positioned in the front-rear, left-right, and up-down directions of the vehicle; the vertical positioning part 2 is parallel to the up-down direction of the vehicle in the length direction, and perpendicular to the side panel sheet metal fitting surface in the width direction; the upper part of one side of the vertical positioning part 2 in the width direction is connected to the rear beam connecting end, and the lower part is provided with a rear beam connecting plate 5 parallel to the side panel sheet metal fitting surface. Thus, it is also positioned in the front-to-back, left-to-right, and up-down directions of the vehicle; at the same time, the side panel assembly 6 and the rear interior panel 7 are installed and positioned by connecting the vertical positioning part 2; through the above settings, the panel bracket is directly physically connected to the side sheet metal of the vehicle body, and provides the installation limit surface and limit point of the side panel assembly 6 and the rear interior panel 7, and also associates with the interior panel components of the cab, that is, the interior components and the body-in-white are physically associated with the panel bracket as the core part, and the interior components are positioned and fastened as a whole, so that the gap surface difference between the interior components is as short as possible.

[0055] This solves the problem in related technologies where the positioning points of different parts are scattered on different vehicle body structural components, resulting in numerous dimensional chains and links in the aesthetic function guarantee between interior parts and between interior parts and surrounding environmental parts, large chain tolerances, frequent unsatisfactory actual vehicle matching effects, and many various gap and surface differences, which cannot meet the needs of continuous improvement of the overall vehicle's aesthetic characteristics and perceived quality.

[0056] The above should be understood as follows: a trim panel bracket was added on the basis of the original design, and then some of the original side panel components were positioned and installed through the trim panel bracket, while the rest were installed in the original way.

[0057] This application also proposes a vehicle that utilizes the aforementioned cab interior trim assembly. The vehicle is a commercial truck, categorized as heavy-duty, medium-duty, and light-duty. The horizontal positioning portion 1 and the vertical positioning portion 2 are manufactured as a single unit and are made of metal or rigid materials.

[0058] A vehicle comprising:

[0059] The above-described interior trim panel assembly has a horizontal positioning part 1 that is attached to the side panel sheet metal, and its two ends are respectively connected to the rear beam 11 and the inner panel 3 of the center pillar; the top of the horizontal positioning part 1 is connected to the upper crossbeam 8 through the upper crossbeam connecting part 4.

[0060] The side panel assembly 6 is connected at its top to the upper crossbeam 8 above; the side panel assembly 6 is connected to the vertical surface of the vertical positioning part 2 on one side in the vehicle's front-rear direction and to the rear interior panel 7.

[0061] refer to Figures 2-7 , Figure 10-12 In some preferred embodiments, the connection method between the side panel assembly 6 and the rear interior panel 7 and the vertical positioning portion 2 is described in detail:

[0062] The vertical positioning part 2 has multiple third mounting holes 201 on its connecting vertical surface, and the multiple third mounting holes 201 are distributed at intervals along the vertical direction of the vehicle; a positioning slot 200 is provided between two adjacent third mounting holes 201.

[0063] The side panel assembly 6 has a locking block 600 on one side in the vehicle's front-rear direction that engages with the positioning slot 200; the rear interior panel 7 has a fitting part that fits with the vertical surface of the vertical positioning part 2, and the fitting part has a first through hole 700 corresponding to the positioning slot 200; the locking block 600 includes a pressing part and an insertion part, and the pressing part has the positioning slot 200.

[0064] When the side panel assembly 6 and the rear interior panel 7 are connected to the vertical positioning part 2, the pressing part contacts the fitting part, and the insertion part passes through the first through hole 700 and the positioning slot 200 in sequence.

[0065] The above structure shows that the vertical positioning part 2 limits the side panel assembly 6 and the rear interior panel 7.

[0066] Further reference Figures 6-10 The side panel assembly 6 includes a side interior panel 601 and a side storage box 602. When installing the side interior panel 601 and the side storage box 602, they need to be assembled beforehand. The connection structure of the assembly is as follows:

[0067] The side interior trim panel 601 has a side storage box mounting groove in the middle. A connecting edge 603 is provided at the edge of the groove, and multiple second and third through holes are provided on the connecting edge 603. Multiple metal clips 604 are provided in each of the second and third through holes, forming a positioning channel between adjacent metal clips 604. The outer periphery of the side storage box 602 has mounting posts 605 corresponding to the second through holes and positioning pins corresponding to the third through holes. A locking block 600 is installed on one side of the side interior trim panel 601 in the vehicle's front-rear direction. The multiple metal clips 604 in the second and third through holes are circularly distributed, with their centers concentric with the center of the second through hole, thus forming a... Figure 9 The six slots shown also have six protrusions around the locating pins.

[0068] When the side interior panel 601 and the side storage box 602 are connected, the mounting post 605 passes through the corresponding second through hole, and multiple metal clips 604 are clamped around its periphery; the positioning pin passes through the corresponding third through hole, and the protrusion on the outer periphery of the positioning pin engages with the positioning channel.

[0069] Alternatively, the second and third through holes can be set on the side storage box 602, and the mounting post 605 and the positioning pin can be set on the side interior panel 601.

[0070] In other words, the number and location of the second and third through holes can be set as needed, and they can be evenly spaced along the trajectory of the connecting edge 603 to limit movement in the front-to-back and up-to-down directions of the vehicle. In addition, the outer periphery of the side storage box 602 fits into the connecting edge 603 to limit movement in the left-to-right direction of the vehicle.

[0071] refer to Figure 1-Figure 5 ,as well as Figures 10-12 The connection structure of the upper crossbeam connecting part 4, the horizontal positioning part 1, the upper crossbeam 8, and the side interior panel 601 is described below:

[0072] Referring to reference 9, the upper crossbeam connecting part 4 includes a plurality of connecting pieces spaced apart along the front-rear direction of the vehicle, and the connecting pieces are provided with first mounting holes 400; the upper crossbeam 8 includes an inner upper crossbeam 800 and an outer upper crossbeam 801, and the outer upper crossbeam 801 is provided with a projection weld nut 802; both the inner upper crossbeam 800 and the outer upper crossbeam 801 are provided with fourth mounting holes 803 corresponding to the projection weld nut 802;

[0073] The upper part of the side panel assembly 6 is provided with a sixth mounting hole 606 corresponding to the first mounting hole 400; the horizontal positioning part 1 and the top of the side panel assembly 6 are attached to each other and connected to the upper crossbeam 8 by bolts that pass through the sixth mounting hole 606, the first mounting hole 400, the fourth mounting hole 803 and the projection weld nut 802 in sequence.

[0074] The above structure shows that the connection between the top of the side interior panel 601 and the inner upper crossbeam 800 shares the first mounting hole 400 that connects to the horizontal positioning part 1 and the inner upper crossbeam 800, which facilitates installation and connection and reduces the number of mounting holes. Thus, in conjunction with the limiting of the side and vertical positioning part 2 of the side interior panel 601 described above, the side interior panel 601 and the rear interior panel 7 are associated and limited.

[0075] Furthermore, the vehicle also includes a curtain rail trim panel 9 and a side roof interior trim panel 10; the top surface of the bottom edge of the side roof interior trim panel 10 in the vertical direction of the vehicle is attached to and connected to the bottom of the inner upper crossbeam 800.

[0076] The top of the side panel assembly 6 and the side roof interior panel 10 have a gap between their corresponding sides in the left-right direction of the vehicle.

[0077] The top of the curtain rail trim panel 9 is abutted and connected to the bottom surface of the side roof interior panel 10 at its bottom edge in the vertical direction of the vehicle. The bottom side of the curtain rail trim panel 9 abuts against the surface of the side panel assembly 6, and covers the connection points of the side panel assembly 6 and the inner upper crossbeam 800, the connection points of the upper crossbeam connecting part 4 and the inner upper crossbeam 800, the connection points of the side roof interior panel 10 and the inner upper crossbeam 800, and the gaps. The top of the curtain rail trim panel 9, the bottom edge of the side roof interior panel 10 in the vertical direction of the vehicle, and the bottom of the inner upper crossbeam 800 are all provided with fifth mounting holes 12. The curtain rail trim panel 9, the side roof interior panel 10, and the inner upper crossbeam 800 are connected by the fifth mounting holes 12 and connecting pins.

[0078] With the above settings, the curtain rail trim panel 9 and the trim panel bracket are positioned on the same side panel sheet metal part, and the matching interface between the upper side panel and the side top panel 10 is blocked, making the gap surface difference between the upper side panel and the side top panel 10 invisible, thus reducing the relative position matching requirements.

[0079] It should be understood that there are no specific restrictions on the specific steps and order of installation of the various components of the interior trim panel assembly, as different installation processes will result in different installation sequences; however, as long as the limiting form of the connection structure described above is guaranteed, it is acceptable.
