Description

Automotive interior spare connection structure

Technical Field

The utility model relates to an automobile parts, concretely relates to automotive interior spare connection structure.

Background

The patent application with the application number of CN202121013639.5 provides a door trim panel and an automobile door, which comprises a plurality of inner panels and a plurality of splicing structures for connecting two adjacent inner panels, wherein each splicing structure comprises a first connecting piece and a second connecting piece which are respectively arranged on the two adjacent inner panels, and the first connecting pieces are connected with the second connecting pieces in a matching manner, so that the inner panels are spliced into an integral structure; the door inner decorative plate also comprises a plurality of positioning structures, and two adjacent inner plates are fixed through the positioning structures. Make adjacent inner panel concatenation location through increasing mosaic structure and location structure, during the welding, only need an operating personnel just can realize the concatenation location of polylith inner panel, simultaneously through setting element firm as an organic whole between the inner panel, skew between two continuous inner panels has been avoided because operating personnel's misoperation when welding leads to, influence the holistic welding effect of car inner panel, solved among the prior art through many operating personnel to door interior plaque fixed-position welding's mode, lead to the poor and low technical problem of assembly efficiency of door interior plaque welding effect.

The splicing structure in the door inner decoration plate and the automobile door is a BOSS column welding structure, the structure only has the fixing function after positioning and welding, and a unilateral clamping hook structure is required to be pre-installed. If the pre-installation is not carried out, the two inner plates are not assembled in place when the screws are screwed or welded, so that gaps or section differences exist in the appearance of parts, and the design requirements are not met. The unilateral clamping hooks need to be arranged in space, the inverted buckle surface is demoulded through the inclined top, the conditions that the stroke of the inclined top of the plastic clamp is insufficient and the space is insufficient frequently occur in part design, and the unilateral clamping hook structure is difficult to arrange or even cannot be arranged. And do the preinstallation through unilateral pothook and still have the abnormal sound risk, receive the temperature influence, expend with heat and contract with cold, cooperation joint size can change, and two rubs at high temperature state have the abnormal sound risk.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, a connecting structure of an automotive interior part comprises a first plastic part 1 and a second plastic part 2, wherein a BOSS column 11 is arranged on the first plastic part 1, a connecting part 21 for connecting with the BOSS column 11 is arranged on the second plastic part 2, an i-shaped through hole 22 and two elastic pieces 23 formed by the i-shaped through hole 22 are arranged at the connecting part 21, the i-shaped through hole 22 comprises two first transverse hole parts arranged in parallel and a second hole part longitudinally communicating with the two first transverse hole parts, two ends of the second hole part in the longitudinal direction are respectively communicated with the middle parts of the two first transverse hole parts in the transverse direction, the two elastic pieces 23 are respectively arranged at two sides of the second hole part, the hole walls of the two first transverse hole parts close to the second hole part are inner side hole walls, the hole walls of the two first transverse hole parts opposite to the inner side hole walls are outer side hole walls 24, the BOSS column 11 penetrates through the i-shaped through hole 22 from the second transverse hole part, and the two elastic pieces 23 clamp the BOSS column 11 and the two first transverse hole parts close to the outer side holes 24.

By adopting the technical scheme, the I-shaped through hole 22 is matched with the BOSS column 11, when the BOSS column 11 passes through the I-shaped through hole 22, the two elastic pieces 23 are extruded to elastically deform towards the passing direction of the BOSS column 11, the BOSS column 11 can be clamped tightly by the two elastic pieces 23, the BOSS column 11 can be prevented from retreating from the I-shaped through hole 22, and therefore, the pre-installation effect is achieved, and the connection of the first plastic part 1 and the second plastic part 2 can be ensured in the conventional transportation process; because the BOSS column 11 is in contact with the outer side hole walls 24 of the two first transverse hole parts close to the outer sides, the position of the BOSS column 11 in the longitudinal direction can be limited, resistance is provided for axial movement of the BOSS column 11, and the pre-installation stability can be further ensured; further, in the welding process, the pre-installed first plastic part 1 and the pre-installed second plastic part 2 are fixed through a welding tool, the BOSS column 11 and the connecting part 21 are fused through the ultrasonic principle by the welding robot arm to play a role in fixing, and the BOSS column 11 and the connecting part 21 cannot generate friction abnormal sound after being fixed; because BOSS post 11 and two first transverse hole portion lean on the outside pore wall 24 contact, at BOSS post 11 and connecting portion 21's fusion in-process for the plastics that melt on the BOSS post 11 can be more fill to two first transverse hole portions, and then promote BOSS post 11 and connecting portion 21 welded fastness.

In some embodiments, the first plastic part 1 is provided with a boss 12 for supporting the second plastic part 2, and the boss post 11 is provided on the boss 12. The boss 12 can reduce the matching difficulty between the first plastic part 1 and the second plastic part 2.

In some embodiments, the top of the BOSS 12 is provided with a first positioning surface 13 perpendicular to the axial direction of the BOSS column 11, and the two elastic sheets 23 are each provided with a second positioning surface 26 for fitting with the first positioning surface 13. The first positioning surface 13 and the second positioning surface 26 are arranged, so that the welding precision of the BOSS column 11 and the connecting part 21 can be ensured.

In some embodiments, the ends of both resilient tabs 23 are provided with guide ramps 25 for guiding the BOSS stud 11 to snap into the second bore portion. The guide inclined plane 25 is arranged, so that the difficulty of the BOSS column 11 in penetrating through the I-shaped through hole 22 can be reduced, and the pre-installation difficulty is reduced. As a preferred embodiment, providing a chamfer at the end of the elastic piece 23 enables a thinner grip portion 27 to be formed at the same time as forming the guide slope 25, the thinner grip portion 27 being more easily fused with the BOSS post 11 during welding.

As a preferred embodiment, the two first transverse hole portions are elongated hole portions each having a width of 1mm in the longitudinal direction, and the two hole walls of the first transverse hole portion extending in the transverse direction are an inner hole wall and an outer hole wall 24, respectively.
