[0028] Example 1

[0029] This embodiment provides a vehicle wrapping trim strip, such as Figures 1-2 As shown, the system includes a skeleton, the front of which is covered with a skin 1. In this embodiment, the automotive trim strip adopts an L-shaped structure, and correspondingly, the skeleton also adopts an L-shaped structure. The shape of the skin 1 matches the shape of the skeleton. To reduce the complexity and cost of the mold, the skeleton adopts a detachable 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 automotive 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 automotive trim strip. An interlocking mechanism is provided between the connecting ends of the first skeleton part 2 and the second skeleton part 3. The interlocking mechanism ensures the surface difference between the front of the first skeleton part 2 and the second skeleton part 3, so that the front of the first skeleton part 2 and the second skeleton part 3 are located on the same arc surface. Therefore, the skin 1 is a whole skin, that is, the first skeleton part 2 and the second skeleton part 3 share a skin 1, eliminating the appearance gap between the first skeleton part 2 and the second skeleton part 3.

[0030] The interlocking mechanism includes a first flange at the connecting end of the first frame part 2 and a second flange 4 at the connecting end of the second frame part 3.

[0031] like Figure 3As shown, the first flanging adopts an L-shaped structure, including a first flanging part 5 and a second flanging part 6 which are perpendicular to each other, one end of the first flanging part 5 is fixed with the end of the connecting end of the first framework part 2, and the first flanging part 5 extends towards the back of the first framework part 2, one end of the first flanging part 5 is fixed with the first framework part 2, and the other end is fixed with one end of the second flanging part 6.

[0032] The end of the first flanging part 5 which is connected with the connecting end of the first framework part 2 is hollowed out to form an insertion cavity 7, the shape of the insertion cavity 7 matches the shape of the first framework part 2, which is an arc-shaped cavity structure, in this embodiment, the cavity surface of the insertion cavity 7 which is close to the outer arc surface of the first framework part 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 with the outer cavity surface of the insertion cavity 7, and the inner edge surface is fixed with the inner cavity surface of the insertion cavity 7.

[0034] A positioning strip 9 is arranged between the adjacent second rib plates 8, and the positioning strip 9 is fixed on the inner cavity surface of the insertion cavity 7.

[0035] As shown in the figure, Figures 4-5 The second flanging 4 adopts an arc-shaped plate which matches the shape of the second framework part 3, the arc-shaped plate is arranged in parallel with the second framework part 3, the end of the arc-shaped plate is fixed on the back edge of the end of the connecting end of the second framework part 3, and 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, and the inner edge surface of the first rib plate 10 is fixed with 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 is matched with the outer cavity surface of the insertion cavity 7, and the outer surface of the positioning strip 9 is matched with the inner arc surface of the arc-shaped plate, through the arrangement of the first rib plate 10, the positioning strip 9 and the second flanging 4, the first framework part 2 and the second framework part 3 are positioned, so that the face difference of the front surfaces of the first framework part 2 and the second framework part 3 meets the requirements, and the front surfaces of the first framework part 2 and the second framework part 3 are located on the same arc surface.

[0038] Further, in order to align the side edges of the first framework part 2 and the second framework part 3, a plurality of insertion slots 11 are arranged on the outer end of the second flanging 4, the insertion 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 insertion slots 11, thereby realizing the positioning of the relative positions of the side edges of the first framework part 2 and the second framework part 3, and aligning the side edges of the first framework part 2 and the second framework part 3 with each other.

[0039] Further, in order to make the second rib plate 8 more convenient to insert into the slot 11, the two ends of the open side of the slot 11 are provided with chamfer structures, which are circular chamfer structures or 45° straight chamfer structures, which can be set by those skilled in the art according to actual needs, and will not be described in detail here.

[0040] The second flanging part 6 of the first flanging part is provided with a fixing hole 12 and a positioning hole 13, and the fixing hole 12 is arranged closer to the first skeleton part 2.

The second flanging part 6 is fixedly connected with the BOSS columns through the fixing holes and fixing members, and the fixing members are 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 is a rectangular hole, and the positioning hole 13 cooperates with a positioning member arranged on the fixing seat to position the second flanging part 6 and the fixing seat, so as to realize the positioning of the distance between the end faces of the connecting ends of the first skeleton part 2 and the second skeleton part 3.

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

[0044] In this embodiment, two first positioning plates 15 are arranged, and the first positioning plates 15 are integrally connected with the rib plates of the corresponding BOSS columns 14. The second positioning plates 16 are arranged between the two first positioning plates 15, on the outer sides of the two first positioning plates 15, and the second positioning plates 16 between the two first positioning plates 15 and the second positioning plates 16 on the outer sides are staggered.

[0045] The first positioning plates 15 and the second positioning plates 16 are provided with protrusions 17 at the intersecting positions, and the protrusions 17 are also intersecting structures. The total size of the protruding part on the first positioning plate 15 along the length direction of the second skeleton part matches the width direction of the positioning hole 13, and the total size of the protruding part on the second positioning plate 16 along the width direction of the second skeleton part 3 matches the length direction of the positioning hole 13. Therefore, the protrusions 17 can abut against the four hole surfaces of the positioning hole 13, realizing the cooperation of the positioning member and the positioning hole 13, and realizing four-way positioning through the cooperation of the positioning member and the positioning hole 13.

[0046] In this embodiment, the distance between the end faces of the first skeleton part 2 and the second skeleton part 3 is 0.1mm-0.2mm after the protrusion 17 is embedded into the positioning hole 13. It can be understood that the end faces of the first skeleton part and the second skeleton part can be made to abut after the protrusion 17 is embedded into the positioning hole 13 according to the actual effect, and only the positions of the positioning member and the positioning hole 13 need to be changed, which will not be described in detail here.

[0047] In the process of relative splicing of the first skeleton part 2 and the second skeleton part 3, the positioning plate and the second flanging part 6 can be extruded and deformed until the protrusion 17 is embedded into the positioning hole 13, the relative positioning of the first skeleton part 2 and the second skeleton part 3 is completed, at this time, the BOSS column 14 is aligned with the fixing hole 12 on the second flanging part 6, the BOSS column and the second flanging part can be fixed by using a bolt or a screw 18, and then the locking and fixing between the first skeleton part 2 and the second skeleton part 3 is realized.

[0048] The back surface of the first skeleton part 2 and the second skeleton part 3 is further provided with a plurality of buckles for fixing the automobile body, the structure and setting mode of the buckle can adopt the prior art, which will not be described in detail here.

[0049] The vehicle cladding trim of the embodiment comprises a first skeleton part 2 and a second skeleton part 3, and the whole trim is in a disassembled manner. Compared with the cladding trim in a whole structure, the complexity of the mold structure is greatly reduced, and the mold cost is reduced. Compared with the traditional disassembled cladding trim, the first skeleton part 2 and the second skeleton part 3 are provided with an interlocking mechanism. Through the cooperation of the first rib plate 10 and the outer cavity surface of the insertion cavity 7, and the cooperation of the positioning strip 9 and the inner arc surface of the second flange 4, the face difference of the front surfaces of the first skeleton part 2 and the second skeleton part 3 can be ensured, so that the front surfaces of the first skeleton part 2 and the second skeleton part 3 are located on the same arc surface. Through the cooperation of the second rib plate 8 and the insertion slot 11 of the second flange 4, the misalignment of the edge of the first skeleton part 2 and the edge of the second skeleton part 3 can be avoided, so that the corresponding edges of the first skeleton part 2 and the second skeleton part 3 are aligned. Through the positioning hole 13 and the protrusion 17 on the positioning plate, the cooperation distance between the end faces of the first skeleton part 3 and the second skeleton part 4 can be ensured. Through the BOSS column 14 and the fixing hole 12, the first skeleton part 2 and the second skeleton part 3 can be locked and fixed. Therefore, through the arrangement of the first rib plate 10, the second rib plate 8, the insertion slot 11, the positioning strip 9 and the positioning member, the cooperation precision of the first skeleton part 2 and the second skeleton part 3 can be ensured, and the gap between the connecting ends of the first skeleton part 2 and the second skeleton part 3 is avoided to be too large, so that the first skeleton part 2 and the second skeleton part 3 can cladding a complete skin 1, that is, the front surfaces of the first skeleton part 2 and the second skeleton part 3 cladding a skin 1. After the whole cladding trim is assembled, the whole cladding trim can be assembled on the vehicle body, the appearance gap of the disassembled cladding trim is eliminated, the appearance is improved, dust and water are avoided to be stored in the gap, and the cladding trim is easy to clean.

The second flange 4 of the second skeleton part 3 is inserted into the insertion cavity 7 of the first flange of the first skeleton part 2. During the insertion process, the outer edge surface of the first rib plate 10 is attached to the outer cavity surface of the insertion cavity 7, and the positioning strip 9 is attached to the inner arc surface of the second flange 4. During the insertion process, the second rib plate 8 is inserted into the insertion slot 11, and the first skeleton part 2 and the second skeleton part 3 move towards 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 skeleton part 2 and the second skeleton part 3 is completed. After the first skeleton part 2 and the second skeleton part 3 are positioned, the bolt or screw 18 is screwed into the fixing hole 12 and the BOSS column 14, so that the first skeleton part 2 and the second skeleton part 3 are locked and fixed, and the whole skeleton is formed.
