Description

Technical Field

[0001] The present invention relates to the technical field of automotive covering trim strips, and particularly to a vehicle covering trim strip, an assembly method and an automobile. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the popularization of automobiles, people pay more attention to the luxury and touch of automotive decoration. The covering process of automotive interiors is increasingly widely used, and the hugging and coherent shapes in areas such as the main and sub instrument panels have gradually won the preference of automotive stylists. The "L"-shaped large trim strip shape that extends from the front of the armrest of the sub instrument panel to the side cover of the instrument panel is becoming more and more common.

[0004] In traditional designs, one method is to directly disassemble this "L"-shaped trim strip. When using this method, separate covering skins are provided for the two parts of the trim strip. During assembly, the two parts of the trim strip are assembled on the vehicle body in a sequential order, which easily leads to poor cooperation between the two parts of the trim strip, and there is a large seam at the connection position between the two parts of the trim strip. On the one hand, it affects the appearance quality, and on the other hand, dust accumulation, water ingress and other problems are likely to occur at the seam, which is not convenient for cleaning.

[0005] Another way is that the overall mold of the trim strip skeleton is taken out of the mold. Since the mold release directions of the skeleton in the front and rear areas are inconsistent, the overall skeleton mold is nearly twice the size of the skeleton disassembly mold, and a large slider needs to be designed in the mold structure at the instrument panel mating position, resulting in a very complex mold structure and a significant increase in mold cost. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a vehicle covering trim strip, an assembly method and an automobile. The trim strip skeleton is disassembled, which reduces the mold cost and avoids the problem of a large seam between the two parts of the trim strip.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] In a first aspect, an embodiment of the present invention provides a vehicle covering trim strip, which includes a skeleton. The front surface of the skeleton is covered with an epidermis. The skeleton includes a first skeleton part and a second skeleton part. An interlocking mechanism is provided between the first skeleton part and the second skeleton part. The interlocking mechanism includes an L-shaped first flanging provided at the connecting end of the first skeleton part and a second flanging provided at the connecting end of the second skeleton part.

The second flanging part is fixedly connected to a fixing seat on the back surface of the second skeleton part through a fixing member. The fixing seat is provided with a positioning member, and the positioning member cooperates with a positioning hole provided in the second flanging part.

[0009] Optionally, the second flanging is an arc-shaped plate fixed to the back surface of the end of the connecting end of the second skeleton part. The shape of the arc-shaped plate matches the shape of the second skeleton part. A plurality of first rib plates are provided on the outer arc surface of the arc-shaped plate.

[0010] Optionally, a plurality of second rib plates are provided. The second rib plates are provided between the inner cavity surface and the outer cavity surface of the insertion cavity.

[0011] Optionally, a positioning strip is provided between adjacent second rib plates. The positioning strip is fixed to the inner cavity surface of the insertion cavity, and the outer side surface of the positioning strip is attached to the inner side surface of the second flanging.

[0015] Optionally, the first skeleton part and the second skeleton part are distributed in an L shape.

[0016] In the second aspect, an embodiment of the present invention provides an assembly method for the vehicle covering trim strip described in the first aspect: the second flange of the second frame part is inserted into the insertion cavity of the first flange of the first frame part, wherein the outer edge surface of the first rib plate is fitted with the outer cavity surface of the insertion cavity, the second rib plate is inserted into the slot provided by the second flange, the first frame part and the second frame part move relative to each other until the positioning piece is embedded in the positioning hole provided by the second flange part, and then the second flange part is fixedly connected to the fixing seat by using the fixing piece, thus completing the assembly of the entire frame, covering the front side of the frame with a skin, completing the assembly of the entire vehicle covering trim strip, and after the assembly of the vehicle covering trim strip is completed, it is assembled as a whole to the body of the car.

At the same time, compared with the traditional disassembled covering trim strip, an interlocking mechanism is provided between the first frame part and the second frame part. The surface difference of the front face of the first frame part and the second frame part can be ensured by the cooperation of the first rib plate and the inner surface of the insertion cavity. The staggered edges of the first frame part and the second frame part can be avoided by the cooperation of the second rib plate and the slot of the second flange. The arrangement can ensure the matching distance between the end faces of the connecting ends of the first frame part and the second frame part. Therefore, through the arrangement of the first rib plate, the second rib plate, the slot and the positioning piece, the matching accuracy of the first frame part and the second frame part can be ensured, and excessive gap between the connecting ends of the first frame part and the second frame part can be avoided, so that the first frame part and the second frame part can be covered with an entire completed skin, and the entire covering trim can be assembled on the vehicle body as a whole, eliminating the appearance gap of the detachable covering trim. While improving the appearance, it avoids dust and moisture from being retained in the gap, making it easy to clean the covering trim. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] In this implementation manner, the surface of the positioning and covering trim strip facing the user is the front side, and the other side is the back side. That is, when the covering trim strip adopts an arc-shaped structure, the outer arc surface is the front side, and the inner arc surface is the back side.

[0028] Embodiment 1

[0029] This embodiment provides a vehicle covering trim strip, as Figure 1 - Figure 2 shown, including a skeleton, and the front side of the skeleton is covered with an epidermis 1. In this embodiment, the vehicle covering trim strip adopts an L-shaped structure. Correspondingly, the skeleton also adopts an L-shaped structure. The shape of the epidermis 1 matches the shape of the skeleton. In order to reduce the complexity of the mold and the mold cost, the skeleton adopts a split structure, including a first skeleton part 2 and a second skeleton part 3. The first skeleton part 2 and the second skeleton part 3 are distributed in an L shape. The shape of the first skeleton part 2 is the same as the shape of the first skeleton part of the current L-shaped vehicle covering trim strip, and the shape of the second skeleton part 3 is the same as the shape of the second skeleton part of the current L-shaped vehicle covering trim strip. An interlocking mechanism is provided between the connection ends of the first skeleton part 2 and the second skeleton part 3. Through the interlocking mechanism, the surface difference on the front side of the first skeleton part 2 and the second skeleton part 3 is ensured, so that the front sides of the first skeleton part 2 and the second skeleton part 3 are located on the same arc surface. Therefore, the epidermis 1 adopts a whole epidermis, that is, the first skeleton part 2 and the second skeleton part 3 share the same epidermis 1, eliminating the appearance seam between the first skeleton part 2 and the second skeleton part 3.

[0030] The interlocking mechanism includes a first flanging provided at the connection end of the first skeleton part 2 and a second flanging 4 provided at the connection end of the second skeleton part 3.

[0031] As Figure 3As shown, the first flanging adopts an L-shaped structure, including a first flanging portion 5 and a second flanging portion 6 that are perpendicular to each other. One end of the first flanging portion 5 is fixed to the end of the connecting end of the first skeleton portion 2, and the first flanging portion 5 extends in the direction of the back surface of the first skeleton portion 2. One end of the first flanging portion 5 is fixed to the first skeleton portion 2, and the other end is perpendicularly fixed to one end of the second flanging portion 6.

[0032] At the root of the first flanging portion 5, that is, at the end of the connecting end of the first flanging portion 5 and the first skeleton portion 2, it is hollowed out to form an insertion cavity 7. The shape of the insertion cavity 7 matches the shape of the first skeleton portion 2 and is an arc-shaped cavity structure. In this embodiment, the cavity surface on the side of the positioning insertion cavity 7 close to the outer arc surface of the first skeleton portion 2 is the outer cavity surface, and the cavity surface opposite to the outer cavity surface is the inner cavity surface.

[0033] A plurality of second rib plates 8 are arranged at equal intervals in the insertion cavity 7. The second rib plates 8 are arranged between the inner cavity surface and the outer cavity surface of the insertion cavity 7. The outer edge surface of the second rib plate 8 is fixed to the outer cavity surface of the insertion cavity 7, and the inner edge surface is fixed to the inner cavity surface of the insertion cavity 7.

[0034] A positioning strip 9 is also provided at the position between adjacent second rib plates 8. The positioning strip 9 is fixed to the inner cavity surface of the insertion cavity 7.

[0035] As Figure 4 - Figure 5 shown, the second flanging 4 adopts an arc-shaped plate that matches the shape of the second skeleton portion 3. The arc-shaped plate is arranged in parallel with the second skeleton portion 3. The end of the arc-shaped plate is fixed to the back edge of the end of the connecting end of the second skeleton portion 3. The arc-shaped plate can be inserted into the insertion cavity 7.

[0036] A plurality of first rib plates 10 are arranged at equal intervals on the outer arc surface of the arc-shaped plate. The inner edge surface of the first rib plate 10 is fixed to the outer arc surface of the arc-shaped plate.

[0037] After the arc-shaped plate is inserted into the insertion cavity 7, the outer edge surface of the first rib plate 10 fits and cooperates with the outer cavity surface of the insertion cavity 7, and the outer side surface of the positioning strip 9 fits and cooperates with the inner arc surface of the arc-shaped plate. Through the settings of the first rib plate 10, the positioning strip 9, and the second flanging 4, the first skeleton portion 2 and the second skeleton portion 3 are positioned, so that the surface difference between the fronts of the first skeleton portion 2 and the second skeleton portion 3 meets the requirements, and the fronts of the first skeleton portion 2 and the second skeleton portion 3 are located on the same arc surface.

[0038] Furthermore, in order to align the side edges of the first skeleton portion 2 and the second skeleton portion 3, a plurality of slots 11 are provided at the outer end of the second flanging 4. The slots 11 match the second rib plates 8. After the second flanging 4 is inserted into the insertion cavity 7, the second rib plates 8 can be inserted into the slots 11, thereby realizing the positioning of the relative positions of the side edges of the first skeleton portion 2 and the second skeleton portion 3, and making the side edges of the first skeleton portion 2 and the second skeleton portion 3 align with each other.

[0039] Furthermore, in order to more conveniently insert the second rib plate 8 into the slot 11, chamfer structures are provided at both ends of the open side of the slot 11. The chamfer structures adopt circular chamfer structures or 45° linear chamfer structures, which can be set by those skilled in the art according to actual needs and will not be described in detail herein.

[0040] A fixing hole 12 and a positioning hole 13 are provided on the second flanging portion 6 of the first flanging. The position of the fixing hole 12 is closer to the first skeleton portion 2. Correspondingly, a fixing seat is provided on the back surface of the connecting end of the second skeleton portion 3.

[0041] In this embodiment, two fixing holes 12 are provided. Correspondingly, two BOSS posts 14 corresponding to the fixing holes one by one are provided on the fixing seat. The second flanging portion 6 is fixedly connected to the BOSS posts through the fixing holes and fixing members. The fixing members adopt threaded fixing members such as bolts or screws 18, which can be selected by those skilled in the art according to actual needs.

[0042] The positioning hole 13 adopts a rectangular hole and cooperates with the positioning member provided on the fixing seat to position the second flanging portion 6 and the fixing seat, thereby realizing the positioning of the distance between the end faces of the connecting ends of the first skeleton portion 2 and the second skeleton portion 3.

[0043] The positioning member includes a plurality of positioning plates arranged vertically and crosswise. The positioning plates are fixed on the back surface, i.e., the inner arc surface, of the second skeleton portion 3. In this embodiment, the positioning plates distributed along the length direction of the second skeleton portion 3 are defined as the first positioning plates 15, and the positioning plates distributed along the width direction of the second skeleton portion 3 are defined as the second positioning plates 16.

[0044] In this embodiment, two first positioning plates 15 are provided, and the rib plates of the first positioning plates 15 are integrally connected to the corresponding BOSS posts 14. A second positioning plate 16 is provided between the two first positioning plates 15, and second positioning plates 16 are provided outside the two first positioning plates 15. The second positioning plate 16 between the two first positioning plates 15 and the second positioning plates 16 outside are arranged staggeredly.

[0045] A protrusion 17 is provided at the cross position of the first positioning plate 15 and the second positioning plate 16. The protrusion 17 is also a cross structure. The total dimension of the protruding portion of the first positioning plate 15 along the length direction of the second skeleton portion matches the width direction of the positioning hole 13, and the total dimension of the protruding portion of the second positioning plate 16 along the width direction of the second skeleton portion 3 matches the length direction of the positioning hole 13. Therefore, the protrusion 17 can abut against the four hole surfaces of the positioning hole 13, realizing the cooperation between the positioning member and the positioning hole 13, and realizing four-way limit through the cooperation between the positioning member and the positioning hole 13.

[0046] In this embodiment, after the protrusion 17 is inserted into the positioning hole 13, the distance between the end faces of the connecting ends of the first frame part 2 and the second frame part 3 is 0.1 mm - 0.2 mm. It can be understood that whether the end faces of the connecting ends of the first frame part and the second frame part are in contact after the protrusion 17 is inserted into the positioning hole 13 can also be confirmed according to the actual effect. Only the positions of the positioning member and the positioning hole 13 need to be changed, and no detailed description will be given here.

[0047] During the relative splicing process of the first frame part 2 and the second frame part 3, the positioning plate and the second flanging part 6 can be squeezed and deformed until the protrusion 17 is inserted into the positioning hole 13, completing the relative positioning of the first frame part 2 and the second frame part 3. At this time, the BOSS post 14 is aligned with the fixing hole 12 on the second flanging part 6, and the BOSS post and the second flanging part can be fixed by using bolts or screws 18, thereby realizing the locking and fixing between the first frame part 2 and the second frame part 3.

[0048] A plurality of buckles are further provided on the back surfaces of the first frame part 2 and the second frame part 3 for fixing to the vehicle body of the automobile. The structure and setting method of the buckles can adopt the prior art, and no detailed description will be given here.

[0049] The vehicle covering trim strip of the present embodiment has a frame including a first frame part 2 and a second frame part 3. The entire trim strip is disassembled. Compared with the covering trim strip of the integral structure, the structural complexity of the mold is greatly reduced, and the mold cost is reduced. At the same time, compared with the traditional disassembled covering trim strip, an interlocking mechanism is provided between the first frame part 2 and the second frame part 3. Through the cooperation of the first rib plate 10 and the outer cavity surface of the insertion cavity 7, the cooperation of the positioning strip 9 and the inner arc surface of the second flange 4, the surface difference of the front faces of the first frame part 2 and the second frame part 3 can be ensured, so that the front faces of the first frame part 2 and the second frame part 3 are located on the same arc surface. Through the cooperation of the second rib plate 8 and the slot 11 of the second flange 4, the side edges of the first frame part 2 and the second frame part 3 can be avoided from being staggered, so that the corresponding side edges of the first frame part 2 and the second frame part 3 are aligned. The setting of the upper protrusion 17 can ensure the matching distance between the end faces of the connecting ends of the first frame part 3 and the second frame part 4, and the first frame part 2 and the second frame part 3 can be locked and fixed through the BOSS column 14 and the fixing hole 12. Therefore, through the setting of the first rib plate 10, the second rib plate 8, the slot 11, the positioning strip 9 and the positioning piece, the matching accuracy of the first frame part 2 and the second frame part 3 can be ensured, and the gap between the connecting ends of the first frame part 2 and the second frame part 3 is avoided to be too large, so that the first frame part 2 and the second frame part 3 can be covered with a whole complete skin 1, that is, the first frame part 2 and the second frame part 3 are covered with a skin 1 on the front side, and the whole covering trim can be assembled on the vehicle body as a whole after being assembled, eliminating the appearance gap of the disassembled covering trim. While improving the appearance, it avoids dust and moisture from being retained in the gap, and facilitates the cleaning of the covering trim.

[0050] Example 2

[0051] The present embodiment provides an assembly method of the vehicle covering trim strip described in Embodiment 1, wherein the second flange 4 of the second frame part 3 is inserted into the insertion cavity 7 of the first flange of the first frame part 2. During the insertion process, the outer edge surface of the first rib plate 10 is in contact with the outer cavity surface of the insertion cavity 7, and the positioning strip 9 is in contact with the inner arc surface of the second flange 4. During the insertion process, the second rib plate 8 is inserted into the slot 11, and the first frame part 2 and the second frame part 3 move toward each other until the protrusion 17 of the positioning plate is embedded in the positioning hole 13. At this time, the mutual positioning of the first frame part 2 and the second frame part 3 is completed. After the first frame part 2 and the second frame part 3 are positioned, bolts or screws 18 are screwed into the fixing holes 12 and the BOSS columns 14 so that the first frame part 2 and the second frame part 3 are locked and fixed to form an integral frame.

[0052] The formed integral frame is covered with a skin 1 matching the shape of the frame, thus completing the assembly of the entire vehicle covering trim. The covering method of the skin 1 can be carried out using existing technology, which will not be described in detail here.

[0053] The assembled vehicle covering trim is assembled to the target position on the vehicle body through snap fasteners. The assembly method can adopt the existing technology and will not be described in detail here.

[0054] With the trim of this embodiment, the two parts of the trim are assembled as a whole after assembly, without the need for the two parts to be assembled successively. Moreover, the two parts of the trim adopt a single skin, eliminating the gap between the two parts. While meeting the aesthetic requirements, it avoids problems such as dust accumulation in the gap and facilitates the cleaning of the covering trim.
