[0053] As Figures 1 - 12 shown, the installation structure of the outer trim panel of the door pillar provided by an embodiment of the present invention includes a pillar sheet metal 1, a plastic snap-in part 2, a sealing strip insert 3 and a pillar outer trim panel 4.

[0054] The plastic snap-in part 2 includes a base plate 21, a sleeve 22 connected to one side of the base plate 21, and a plug board 23 connected to the other side of the base plate 21.

[0055] The sleeve 22 is provided with sleeve claws 221, and the plug board 23 is provided with plug board claws 231.

[0056] One side of the base plate 21 facing the sleeve 22 is provided with a limit bump 24, and the limit bump 24 is arranged staggeredly with the sleeve claws 221 in the circumferential direction.

[0057] The top of the pillar sheet metal 1 is provided with a sheet metal snap hole 11 for the sleeve 22 to pass through.

[0058] The edge of the sheet metal snap hole 11 is provided with a snap hole limit groove 12, which is used for the sleeve claws 221 to pass through and for cooperating with the limit bump 24 for limiting.

[0059] The base plate 21 is attached to the outer surface of the pillar sheet metal 1, the sleeve 22 passes through the sheet metal snap hole 11, the sleeve claws 221 are snap-connected to the inner surface of the pillar sheet metal 1, and the limit bump 24 is located in the snap hole limit groove 12.

[0060] The sealing strip insert 3 includes a connecting plate 31, and the connecting plate 31 is provided with a connecting plate through hole 311.

[0061] The plug board 23 passes through the connecting plate through hole 311, and the plug board claws 231 are snap-connected to the outer surface of the connecting plate 31.

[0062] The outer surface of the connecting plate 31 is provided with an insert snap structure 32, and the inner surface of the pillar outer trim panel 4 is provided with an outer trim panel snap structure 41, and the outer trim panel snap structure 41 is snap-connected to the insert snap structure 32.

[0063] The installation structure of the outer trim panel of the door pillar provided by the present invention is the pillar part of the door structure, which mainly refers to the installation structure in the top area of the pillar, and the corners of this top area need to be sealed with a sealing strip insert or a sealing strip guide groove.

[0064] The installation structure of the exterior trim panel of the door pillar includes a pillar sheet metal 1, a plastic snap - fitting 2, a seal insert 3, and a pillar exterior trim panel 4. An interior trim panel 5 of the pillar is installed on the inner side of the pillar sheet metal 1. The seal insert 3 is fixed to the outer side of the pillar sheet metal 1 through the plastic snap - fitting 2, and the pillar exterior trim panel 4 is snap - connected to the seal insert 3.

[0065] The plastic snap - fitting 2 has the ability of elastic deformation and will absorb the gap or tolerance between parts during the snap - connection process.

[0066] The plastic snap - fitting 2 includes a base plate 21, a sleeve 22, a plug plate 23, and a limit lug 24. The sleeve 22 is connected to the inner side of the base plate 21, and the plug plate 23 is connected to the outer side of the base plate 21. On the circumferential surface of the sleeve 22, there are radially protruding sleeve claws 221, and the sleeve claws 221 have inclined guiding slopes. On the plug plate 23, there are plug plate claws 231 protruding radially along the sleeve 22. The plug plate claws 231 also have inclined guiding slopes. The limit lug 24 is directly arranged on the inner side of the base plate 21, and the limit lug 24 and the sleeve claws 221 are arranged staggeredly in the circumferential direction. Along the axial direction of the sleeve 22, the limit lug 24 and the sleeve claws 221 are arranged at intervals.

[0067] At the top of the pillar sheet metal 1, there is a sheet - metal snap - hole 11 for the sleeve 22 to pass through and snap - connect. At the edge of the sheet - metal snap - hole 11, there is a snap - hole limit groove 12, and the number of the snap - hole limit grooves 12 is the same as the number of the limit lugs 24. The snap - hole limit groove 12 can be used for the sleeve claws 221 to pass through so that the sleeve claws 221 move to the inner side of the pillar sheet metal 1. The snap - hole limit groove 12 can also be used in cooperation with the limit lugs 24 for positioning to prevent the plastic snap - fitting 2 from rotating.

[0068] Specifically, when assembling the plastic snap - fitting 2 with the pillar sheet metal 1, first rotate the plastic snap - fitting 2 so that the sleeve claws 221 are aligned with the snap - hole limit grooves 12, and then move the plastic snap - fitting 2 towards the inner side of the pillar sheet metal 1. After the sleeve claws 221 pass through the snap - hole limit grooves 12, rotate the plastic snap - fitting 2 again so that the limit lugs 24 are aligned with the snap - hole limit grooves 12. When the base plate 21 is close to the outer surface of the pillar sheet metal 1, the sleeve claws 221 are snap - connected to the inner surface of the pillar sheet metal 1 to achieve axial positioning, and the limit lugs 24 are in the snap - hole limit grooves 12 to achieve circumferential positioning.

[0069] The seal insert 3 is used to seal the top - corner area between the pillar sheet metal 1 and the pillar exterior trim panel 4. The seal insert 3 includes a seal strip and a connecting plate 31 connected below the seal strip. The connecting plate 31 is a plastic plate and is used for snap - connecting and assembling with the plastic snap - fitting 2. On the connecting plate 31, there are connecting - plate through - holes 311, and the number of the connecting - plate through - holes 311 is the same as the number of the plug plates 23. The connecting - plate through - holes 311 are used for the plug plates 23 to pass through outward.

[0070] During assembly, align the through-hole 311 of the connecting plate with the insertion plate 23, and push the sealing strip insert 3 inward so that the insertion plate 23 passes through the through-hole 311 of the connecting plate outward. When installed in place, the insertion plate claw 231 is clamped with the outer surface of the connecting plate 31.

[0071] On one side of the connecting plate 31 facing the outer trim panel 4 of the column, an insert clamping structure 32 is provided. On one side of the outer trim panel 4 of the column facing the sealing strip insert 3, an outer trim panel clamping structure 41 is provided. The outer trim panel clamping structure 41 is clamped with the insert clamping structure 32 to clamp the outer trim panel 4 of the column and the sealing strip insert 3 together, thereby positioning the top of the outer trim panel 4 of the column on the column sheet metal 1.

[0072] Thus, for the door column outer trim panel installation structure provided by the present invention, the plastic clamping part 2 is directly clamped with the column sheet metal 1, the operation is simple, the traditional assembly methods of metal screws, nuts and L-shaped sheet metal tongues are cancelled, and the defect that the sheet metal tongue is easy to deform is avoided. The plastic clamping part 2, the sealing strip insert 3 and the outer trim panel 4 of the column are locked pairwise, and the elastic characteristics of the plastic material are utilized to absorb the tolerances between parts and improve the matching stability.

[0073] In one embodiment, as Figures 4 - 7 shown, two sleeve claws 221 are evenly distributed along the circumferential direction on the sleeve 22, and two limit bumps 24 are provided on the inner surface of the substrate 21.

[0074] Each limit bump 24 is located between two sleeve claws 221, and the central angle between the limit bump 24 and the sleeve claw 221 is 90°.

[0075] In this embodiment, two symmetrically arranged sleeve claws 221 are provided on the sleeve 22, and one limit bump 24 is provided on each of the opposite sides of the substrate 21 where the sleeve 22 is located. Along the circumferential direction, the central angle between each limit bump 24 and the sleeve claw 221 is 90°. A card hole limit groove 12 is provided on each of the opposite sides of the sheet metal card hole 11.

[0076] After passing the sleeve claw 221 through the card hole limit groove 12 and then rotating 90°, the limit bump 24 can be aligned with the card hole limit groove 12, which is convenient for operation. Both sleeve claws 221 are clamped with the inner surface of the column sheet metal 1, improving the connection stability. The two limit bumps 24 are located in the two card hole limit grooves 12, improving the circumferential limit effect of the plastic clamping part 2.

[0077] In one embodiment, as Figure 6 and Figure 8 shown, two insertion plates 23 are provided at intervals on one side of the substrate 21 facing the sealing strip insert 3, and each insertion plate 23 has an insertion plate claw 231.

[0078] The two insertion plates 23 are arranged symmetrically about the center axis of the sleeve 22.

[0079] In this embodiment, two insertion plates 23 are connected to the substrate 21. The two insertion plates 23 are arranged symmetrically about the center axis of the sleeve 22. Each insertion plate 23 is provided with an insertion plate claw 231. In the circumferential direction, each limiting bump 24 is located between two insertion plate claws 231. The central angle between the limiting bump 24 and the insertion plate claw 231 is 90°, that is, each insertion plate claw 231 and a sleeve claw 221 are on the same side of the axis of the sleeve 22.

[0080] Correspondingly, two connecting plate through holes 311 are provided on the connecting plate 31. During assembly, the two insertion plates 23 respectively pass outward through the two connecting plate through holes 311, and the two insertion plate claws 231 are both clamped with the outer surface of the connecting plate 31, improving the connection stability between the sealing strip insert 3 and the plastic clamping member 2.

[0081] In one of the embodiments, as Figure 6 and Figures 8 - 11 shown, the insertion plate 23 is arc-shaped, and the connecting plate through hole 311 is a linear through hole. The width of the connecting plate through hole 311 is D, the radius of the insertion plate 23 is R, and the central angle of the insertion plate 23 is α. Then, R - R×cos(α / 2) ≥ D.

[0082] That is, the maximum distance D0 between the plane where the two side edges of the insertion plate 23 are located and the arc surface of the insertion plate 23 is D0 = R - R×cos(α / 2). D0 is slightly larger than D. When the insertion plate 23 passes through the connecting plate through hole 311, the insertion plate 23 will be appropriately deformed by extrusion, playing a pre-tightening role between the insertion plate 23 and the connecting plate 31.

[0083] In one of the embodiments, as Figure 6 and Figure 8 shown, a limiting rib 25 is provided on the outer surface of the substrate 21. The limiting rib 25 and the insertion plate 23 are arranged staggeredly in the circumferential direction.

[0084] The limiting rib 25 and the limiting bump 24 are aligned inside and outside. When assembling the sealing strip insert 3, when the inner surface of the connecting plate 31 contacts the limiting rib 25, it means that the sealing strip insert 3 is installed in place. The limiting rib 25 abuts against the connecting plate 31 to ensure that the insertion plate claw 231 is clamped with the outer surface of the connecting plate 31.

[0085] In one of the embodiments, as Figure 4 and Figure 8 shown, the top of the outer surface of the column sheet metal 1 has a sheet metal groove 13, and the sheet metal card hole 11 is opened on the groove bottom plate 131 of the sheet metal groove 13.

[0086] The substrate 21 is assembled in the sheet metal groove 13, and the sleeve claw 221 is clamped with the inner surface of the groove bottom plate 131.

[0087] In this embodiment, a sheet metal groove 13 is formed by recessing at the top of the outer surface of the column sheet metal 1, and the sheet metal card hole 11 is opened on the groove bottom plate 131 of the sheet metal groove 13. The substrate 21 is located in the sheet metal groove 13. The sheet metal groove 13 plays a role in restricting the movement of the substrate 21, facilitating assembly, and also helping to improve the assembly stability between the substrate 21 and the column sheet metal 1.

[0088] In one of the embodiments, as Figures 9 - 14 shown, the insert clamping structure 32 includes an insert plate 321 connected to the connecting plate 31 and insert claws 322 provided on the insert plate 321.

[0089] The insert plate 321 and the plug plate 23 are arranged staggeredly in the circumferential direction.

[0090] The exterior panel clamping structure 41 includes a clamping plate 411 and a clamping plate through hole 412 provided on the clamping plate 411.

[0091] The insert plate 321 passes through the clamping plate through hole 412, and the insert claws 322 are clamped with the outer surface of the clamping plate 411.

[0092] In this embodiment, the insert clamping structure 32 includes an insert plate 321 and insert claws 322. The insert plate 321 is connected to the connecting plate 31 and extends outward. Both the insert plate 321 and the insert claws 322 are plastic parts. The insert claws 322 are integrally provided on the insert plate 321. The insert claws 322 have guiding inclined surfaces. The insert plate 321 and the plug plate 23 are arranged staggeredly in the circumferential direction, and the central angle between them is 90°, avoiding interference.

[0093] The exterior panel clamping structure 41 includes a clamping plate 411 and a clamping plate through hole 412. The clamping plate through hole 412 is provided on the clamping plate 411, and the number of the clamping plate through holes 412 is the same as the number of the insert plates 321. The clamping plate 411 is a plastic plate, and the clamping plate 411 is connected to the inner side of the column exterior panel 4. There is a spaced space between the clamping plate 411 and the column exterior panel 4 to allow the insert plate 321 to pass outward through the clamping plate through hole 412.

[0094] During assembly, align the clamping plate through hole 412 with the insert plate 321, and push the column exterior panel 4 inward, so that the insert plate 321 passes outward through the clamping plate through hole 412, and the insert claws 322 are clamped with the outer surface of the clamping plate 411 to assemble the column exterior panel 4 onto the column sheet metal 1.

[0095] In one of the embodiments, as Figure 9 and Figure 13As shown, the insert clamping structure 32 includes two insert plates 321, which are arranged on the upper and lower sides of the through hole 311 of the connecting plate. Each insert plate 321 has an insert plate claw 322.

[0096] Correspondingly, two card plate through holes 412 are arranged on the card plate 411 at intervals up and down.

[0097] The two insert plates 321 respectively pass through the two card plate through holes 412, and each insert plate claw 322 is clamped with the outer surface of the card plate 411.

[0098] In this embodiment, the insert clamping structure 32 includes two insert plates 321 arranged on the upper and lower sides of the through hole 311 of the connecting plate. Each insert plate 321 has an insert plate claw 322. Two card plate through holes 412 are correspondingly formed on the card plate 411 at intervals up and down.

[0099] During assembly, the two insert plates 321 respectively pass through the two card plate through holes 412, and each insert plate claw 322 is clamped with the outer surface of the card plate 411, improving the clamping stability between the exterior trim panel clamping structure 41 and the insert clamping structure 32.

[0100] In one of the embodiments, as Figure 9 and Figure 13 shown, the insert plate 321 is arc-shaped, and the card plate through hole 412 is a straight through hole. The width of the card plate through hole 412 is d, the radius of the insert plate 321 is r, and the central angle of the insert plate 321 is β. Then, r - r×cos(β / 2) ≥ d.

[0101] That is to say, the maximum distance d0 between the plane where the two side edges of the insert plate 321 are located and the arc surface of the insert plate 321 is d0 = r - r×cos(β / 2). d0 is slightly larger than d. When the insert plate 321 passes through the card plate through hole 412, the insert plate 321 will be appropriately deformed under extrusion, playing a pre-tightening role between the insert plate 321 and the card plate 411.

[0102] A vehicle provided by an embodiment of the present invention includes the exterior trim panel mounting structure of the door pillar described in any of the foregoing embodiments.

[0103] According to needs, the above technical solutions can be combined to achieve the best technical effect.

[0104] The above are only the principles and preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, based on the principles of the present invention, several other variants can be made, which should also be regarded as the protection scope of the present invention.
