Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles and relates to a connecting piece and a vehicle door structure. Background Art

[0002] Vehicle doors come in two types: frameless and framed. Frameless vehicles require side trims and corner window trims, with their ends aligned. Sealing strips are required within the side trims to seal the door glass, while corner window trims typically serve a decorative purpose. Therefore, the structures of door frame trims and corner window trims are typically different. During assembly, the relative positions of the side and corner window trims must be carefully controlled to ensure their ends align as closely as possible.

[0003] In response to this, a connector structure has begun to appear on the market to align the end of the side trim strip with the end of the corner window trim strip, such as the vehicle body side trim strip assembly structure and vehicle disclosed in CN116620177A, which includes: a connector, the connector including a first segment and a second segment, the first segment extending into the first assembly space, and the second segment extending into the second assembly space, so that the end of the door frame trim strip is connected to the end of the corner window trim strip; Figure 1 As shown, the currently commonly used connector structure cannot absorb longitudinal and vertical tolerances, that is, there is a gap h1 between the first mounting joint, a gap h2 between the second mounting structure, and a gap l between the side wall. This will lead to poor positioning and correction effects of the connector. At this time, the actual vehicle will have large discontinuities due to the offset and torsion of the product, resulting in poor appearance and poor consistency in the appearance of the docking position.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figure 2-Figure 5 As shown, a connecting piece includes:

[0028] The first connecting portion 100 includes a first connecting section 101 , and the first connecting section 101 is used to connect with the rear quarter window molding 304 ;

[0029] The second connecting portion 200 is connected to the first connecting portion 100. The second connecting portion 200 includes a second connecting segment 201 arranged on the first connecting segment 101. A first abutting edge 202 and a second abutting edge 203 are respectively provided on both sides of the second connecting segment 201. The second connecting segment 201 is used to abut against the cavity wall 301 of the side decorative strip 300. The end of the first abutting edge 202 is used to abut against the first mounting structure 302. The outer end surface of the first abutting edge 202 is used to abut against the cavity wall 301. The end of the second abutting edge 203 is used to abut against the connecting edge 305 between the second mounting structure 303 and the cavity wall 301. An elastic portion is provided between the first abutting edge 202 or the second abutting edge 203 and the second connecting segment 201. The straight-line distance between the outer end surface of the first abutting edge 202 and the outer end surface of the second abutting edge 203 is greater than the maximum installation distance of the cavity wall 301.

[0030] In this embodiment, when the second connecting section 201 is connected to the side panel decorative strip 300, the end of the first abutting edge 202 is used to abut against the first mounting structure 302, and the outer end surface of the first abutting edge 202 is used to abut against the cavity wall 301, so as to realize the longitudinal and vertical positioning of the first abutting edge 202 and the side panel decorative strip 300; when the second abutting edge 203 is installed with the second mounting structure 303, it will be squeezed by the second mounting structure 303, so that the first abutting edge 202 or the second abutting edge 202 can be pressed against the cavity wall 301. The abutting edge 203 is elastically deformed relative to the second connecting section 201. At this time, the second abutting edge 203 abuts against the connecting edge 305 between the second mounting structure 303 and the cavity wall 301. The first abutting edge 202 and the second abutting edge 203 respectively maintain a stable connection with the corresponding first mounting structure 302 and the second mounting structure 303 under the elastic force of the elastic part, and there will be no gap in the connection between the first abutting edge 202 and the second abutting edge 203 and the side decorative strip 300.

[0031] It is worth mentioning that the straight-line distance between the outer end surface of the first abutting edge 202 and the outer end surface of the second abutting edge 203 is greater than the maximum installation distance of the cavity wall 301, which means that there is interference when the connecting part is connected to the side decorative strip 300. Only then will the side decorative strip 300 squeeze the first abutting edge 202 or the second abutting edge to cause it to deform.

[0032] Specifically, as shown in the figure, the direction from the first abutting edge 202 to the second abutting edge 203 is the longitudinal direction Y, and the vertical direction of the first abutting edge 202 is the vertical direction Z.

[0033] Preferably, when the first abutting edge 202 is connected to the first mounting structure 302, the outer end surface of the first abutting edge 202 abuts against the cavity wall 301, and a gap is left between the end of the first abutting edge 202 and the cavity wall 301 of the side decorative strip 300; when the second abutting edge 203 is connected to the second mounting structure 303, a gap is left between the outer end surface of the second abutting edge 203 and the cavity wall 301, and the end of the second abutting edge 203 abuts against the connecting edge 305 of the second mounting structure 303 and the cavity wall 301.

[0034] In this embodiment, the first abutting edge 202 needs to be positioned in the vertical and longitudinal directions, so it needs to have connection points with the side decorative strip 300 in both the vertical and longitudinal directions to achieve positioning. Then the outer end face of the first abutting edge 202 abuts against the cavity wall 301 to achieve longitudinal positioning, and a gap is left between the end of the first abutting edge 202 and the cavity wall 301 of the side decorative strip 300, so that the end of the first abutting edge 202 can abut against the first mounting structure 302 to achieve vertical positioning. It can be understood that the outer end face of the first abutting edge 202 protrudes from its end.

[0035] Preferably, the elastic portion includes an elastic groove 204 arranged on the second connecting section 201 and having an opening at one end, the first groove wall of the elastic groove 204 is arranged on the second connecting section 201, and the second side wall of the elastic groove 204 is arranged on the first abutting edge 202 or the second abutting edge 203.

[0036] In this embodiment, in order to achieve elastic deformation of the first abutting edge 202 or the second abutting edge 203, an elastic groove 204 is opened on the second connecting section 201, and the elastic groove 204 has an open end, so that under the extrusion action of the side decorative strip 300, the first abutting edge 202 or the second abutting edge 203 can be deformed toward the direction of the elastic groove 204, that is, it can be deformed in the longitudinal and vertical directions.

[0037] Further preferably, the first groove wall includes an integrally arranged deformation edge 205 and an extension edge 206, the deformation edge 205 is located on the second connecting section 201, the extension edge 206 extends from the second connecting section 201 toward the first abutment plate 202 or the second abutment plate 203, and an opening of the elastic groove 204 is formed between the extension edge 206 and the cavity wall 301, the opening of the elastic groove 204 divides the first abutment edge 202 or the second abutment edge 203 into a deformation section 207 and a limiting section 208, the deformation section 207 is used to abut against the connecting edge 305 between the second mounting structure 303 and the cavity wall 301 of the side decorative strip 300, and the outer edge of the deformation section 207 protrudes from the limiting section 208.

[0038] In this embodiment, the setting of the elastic groove 204 allows the first abutting edge 202 or the second abutting edge 203 to be deformed relative to the second connecting section 201. In order to control the elastic deformation amount of the first abutting edge 202 or the second abutting edge 203 to avoid it from being broken under the extrusion of the side panel decorative strip 300, the first abutting edge 202 is divided into a deformation section 207 and a limiting section 208 through the structure of the elastic groove 204, and the outer edge of the deformation section 207 protrudes from the limiting section 208. When the second connecting section 201 is installed with it, the deformation section 207 is abutted against the first mounting structure 302. When the deformation amount of the deformation section 207 exceeds a preset value, the deformation section 207 is abutted against the first mounting structure 302.

[0039] Further preferably, the outer edge of the deformation section 207 is gradually tilted outward along the direction of the deformation section 207 toward the limiting section 208, so that as the connecting piece extends into the side panel decorative strip 300, the abutment force between the deformation section 207 and the side panel decorative strip 300 gradually increases, thereby facilitating the connection between the connecting piece and the side panel decorative strip 300.

[0040] Further preferably, the elastic portion is located between the second abutting edge 203 and the second connecting section 201 .

[0041] In this embodiment, the first abutting edge 202 is used for longitudinal and vertical positioning, so during installation, its structural stability helps to ensure positioning accuracy, and the function of the second abutting edge 203 is to maintain the stable connection of the second connecting section 201 in the side decorative strip 300, so the elastic part is arranged between the second abutting edge 203 and the second connecting section 201.

[0042] Further preferably, along the direction from the first connecting segment 101 to the second connecting segment 201 , a guide installation corner 209 is provided at the outermost corner of the second connecting segment 201 .

[0043] In this embodiment, in order to facilitate the installation of the second connecting section 201 , a guide installation corner 209 is provided at the outermost corner of the second connecting section 201 for installation guidance.

[0044] It is worth mentioning that the first connecting section 101 and the second connecting section 201 are integrally arranged or fixed by welding.
