Description

OPENING BRACKET FOR VEHICLES WITH SUN ROOF

The present invention relates to an opening bracket for an automobile having a sunroof, and more specifically, to an assembly clip that is mounted on an opening bracket and used when assembling the opening bracket to a headliner, by being integrally molded when the opening bracket is molded, the assembly clip does not need to be manufactured separately, thereby reducing assembly costs, and also preventing problems that may occur due to the assembly clip not being mounted in a predetermined position in advance. At this time, the assembly clip is integrally injection-molded when the opening bracket is injection-molded, thereby being integrally molded without a separate manufacturing process, so that assembly can be performed at once without the mounting position being deviated.

In general, an opening is formed through the headliner of a car equipped with a sunroof at a position facing the sunroof, and an opening bracket is mounted on the edge of the opening. At this time, the opening bracket is fixed using clips or fasteners having various structures, such as those described in (Patent Document 1) to (Patent Document 3) below.

In particular, the purpose of this invention is to provide a mounting structure for an auxiliary handle fixture for an automobile, in which the protrusion formed in the base is configured to be assembled by settling in a position formed in the handle plate, so that not only the mounting position can be easily identified, but also the occurrence of joints can be minimized during assembly.

Korean Patent No. 10-2525565 (Registration Date: 2023.04.20) Korean Patent Publication No. 10-2018-0066349 (Published on: 2018.06.19) Korean Patent Publication No. 10-2020-0094239 (Publication Date: 2020.08.07)

However, these conventional opening brackets and the clips (or fasteners) that mount the headliner have the following problems:

(1) Since the clip must be manufactured and used separately from the opening bracket, a process for manufacturing the clip, increased cost when manufacturing the clip, and a process for mounting the completed clip on the opening bracket are required.

(2) This not only increases the number of assembly processes, but also includes additional costs associated with separately manufacturing and managing clips.

(3) In addition, if the clip mounted on the opening bracket is not accurately assembled in the designated position after being assembled to the headliner, the clip may come off or become separated, resulting in poor assembly.

(4) In addition, at least five clips are installed in one opening bracket to assemble it to the headliner, and if even one of the clips is not assembled properly, it will not only result in a defective assembly, but may also result in a defective quality of the opening bracket.

The present invention has taken these points into consideration, and the purpose of the present invention is to provide an opening bracket for an automobile equipped with a sunroof, which enables easy and convenient assembly of the opening bracket to a head lining by forming an assembly clip integrally with the opening bracket when forming the opening bracket, and reduces manufacturing costs by eliminating the process of mounting the assembly clip to the opening bracket and the process of manufacturing the assembly clip.

In particular, the present invention has another purpose of providing an opening bracket for an automobile equipped with a sunroof, in which the opening bracket and the assembly clip are formed integrally by injection molding, thereby enabling easy assembly by only forming the assembly clip integrally through the process of manufacturing the opening bracket without any additional configuration or manufacturing process.

In addition, the present invention has another purpose of providing an opening bracket for a car with a sunroof, which not only prevents incorrect assembly of the assembly clip into the opening bracket by forming the assembly clip integrally with the opening bracket, but also allows anyone to easily and conveniently assemble the opening bracket by pressing it against the headliner.

In order to achieve these objects, the present invention provides an opening bracket for a car with a sunroof, comprising: a bracket body (100) formed so as to be installed at an edge of an opening (O) formed in a headliner (H) so as to allow the installation of a sunroof; wherein the bracket body (100) has a plurality of assembly clips (110) integrally formed at an edge portion facing the headliner (H); wherein the assembly clips (110) include: a base (111) integrally formed at a seating surface for forming the assembly clips (110) in the bracket body (100); at least two engaging pieces (112) formed so as to spread out toward the base (111) and then narrow again at the ends of columns (112a) protruding outward from the central portion of the base (111); And it is characterized by including an elastic piece (113) which is formed to spread outwardly on each side centered on the catch piece (112) in the base (111) and elastically supports the surface of the headliner (H) caught on the catch piece (112).

In particular, the bracket body (100) and the assembly clip (110) are characterized by being formed as one piece through injection molding.

The opening bracket for a car with a sunroof according to the present invention has the following effects.

(1) Since the assembly clip portion used when assembling the opening bracket to the headliner is formed integrally with the opening bracket, not only does it eliminate the need to separately manufacture the assembly clip, but also the process of assembling the assembly clip to the opening bracket can be eliminated, thereby reducing manufacturing costs.

(2) In addition, since the assembly clip is integrally formed with the opening bracket, the assembly clip can be prevented from detaching or coming off from the opening bracket due to vibrations generated when the car is driven, when assembling the opening bracket to the headliner or after assembly. This can prevent noise or vibration that may occur due to detachment of the assembly clip from the opening bracket or failure to be completely assembled.

(3) Meanwhile, since the assembly clip is formed integrally with the opening bracket by injection molding, not only can a complex shape be formed easily and conveniently at once, but it can also be conveniently used and assembled.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the attached drawings. Prior to this, the terms or words used in this specification and claims should not be interpreted as limited to their usual or dictionary meanings, and should be interpreted as meanings and concepts that conform to the technical idea of the present invention, based on the principle that the inventor can appropriately define the concept of the term in order to explain his own invention in the best way.

Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modifications that can replace them at the time of filing this application.

[Configuration of opening bracket for automobile with sunroof]

An opening bracket for a car with a sunroof according to the present invention includes a bracket body (100) installed at an edge portion of an opening (O) formed in a headliner (H) for installing a sunroof, as shown in [FIGS. 1] to [FIGS. 4].

In particular, the bracket body (100) is configured so that the assembly clip (110) used when assembling the opening bracket to the headliner (H) is integrally formed, so that the assembly clip (110) does not need to be manufactured separately, thereby reducing the number of assembly processes and reducing manufacturing costs, and also suppressing noise and abnormal sounds that may occur at the assembly portion.

In addition, at this time, the assembly clip (110) is configured with at least two catch pieces (112) that are forcibly inserted into holes formed in the headliner (H) on the surface of the base (111) integrally formed with the bracket body (100) to elastically deform and then return to the original state to perform a catch function, and an elastic piece (113) that can pressurize the headliner (H) from the other side together with the catch pieces (112) centered on the headliner (H), so that the headliner (H) can be inserted between these catch pieces (112) and elastic pieces (113) to be firmly supported and fixed.

Lastly, the assembly clip (110) is integrally injection-molded when the bracket body (100) described above is injection-molded, thereby manufacturing the assembly clip (110) together with the bracket body (100) so that it can be used easily and conveniently.

This configuration will be described in more detail with reference to the attached drawings, as follows. Here, the drawing symbol "H" represents a headliner, which is an interior finishing material mounted facing the roof panel in the interior of a vehicle, and "O" represents an opening formed to penetrate the headliner according to the installation of a sunroof in a vehicle equipped with a sunroof.

a. Bracket body

The bracket body (100) is installed in close contact with the edge portion of the opening (O) formed in the headliner (H), as shown in [Fig. 1] to [Fig. 3]. At this time, the bracket body (100) is configured to be installed in close contact with the edge portion of the opening (O) formed to penetrate the headliner (H) when the sunroof is mounted on the roof panel.

And, as shown in [FIG. 3] and [FIG. 4], the bracket body (100) is configured to have an assembly clip (110) integrally formed so as to be fixed to the headliner (H). The assembly clips (110) are each mounted on a seat surface formed at a predetermined interval so that the bracket body (100) does not sag when the headliner (H) is mounted inside the car. In [FIG. 2] and [FIG. 3], three assembly clips (110) are integrally formed on the long side, and two assembly clips (110) are integrally formed on the short side, respectively. However, anyone skilled in the art will easily recognize that the number and interval of the assembly clips (110) may vary depending on the overall shape and size of the bracket body (100).

In addition, it is preferable that the bracket body (100) be formed by injection molding so that even a complex shape can be easily manufactured and conveniently assembled for use. Of course, it is also preferable that the assembly clip (110) described later be manufactured by integral injection molding when the bracket body (100) is injection molded.

B. Assembly clip

The assembly clip (110) is integrally formed on the surface of the bracket body (100) facing the edge portion of the opening (O) when the bracket body (100) is mounted on the edge portion of the opening (O), as shown in [Fig. 2] to [Fig. 4].

At this time, the assembly clip (110) is formed integrally with the bracket body (100) by determining the interval or number between the assembly clips (110) so that the bracket body (100) can always be maintained in a close contact state without sagging when the bracket body (100) is assembled to the headliner (H), as shown in [Fig. 2] to [Fig. 4].

As described above, the above assembly clip (110) is formed integrally with the bracket body (100), and it is preferable to injection-mold the bracket body (100) integrally with the assembly clip (110) when injection-molding it. This eliminates the need to separately manufacture the assembly clip (110), and since the assembly clip (110) does not need to be assembled to the bracket body (100), the number of assembly processes is reduced, and by reducing the number of assembly points, noise and abnormal noise can be reduced.

Meanwhile, the above assembly clip (110) includes a base (111), at least two catch pieces (112), and an elastic piece (113), as shown in [Fig. 3] and [Fig. 4].

1. Base

The base (111) is formed on the seat surface where the assembly clip (110) is integrally formed in the bracket body (100), as shown in [Fig. 3] and [Fig. 4]. At this time, the base (111) may be formed integrally with the seat surface, or may be formed separately from the seat surface.

In addition, it is preferable that the base (111) be formed with a thickness that can provide sufficient support so that the bracket body (100) does not detach or fall off when the hook piece (112) described later is elastically bonded to the headliner (H).

2. The hanging part

The hanging piece (112) is formed integrally with the base (111) described above, as shown in [Fig. 3] and [Fig. 4].

At this time, the catch piece (112) is formed to be wider as it moves toward the base (111) from the end of the pillar (112a) protruding outward from the middle portion of the base (111), as shown in [Fig. 3] and [Fig. 4]. In addition, a protrusion is formed at the end of the catch piece (112) so that when inserted into a hole formed in the headliner (H), it narrows and then expands back to its original state, and this protrusion is configured to catch on the edge of the hole to perform a catch function.

Meanwhile, in a preferred embodiment of the present invention, at least two of the catch pieces (112) are formed to protrude around the pillar (112a). At this time, the catch pieces (112) are configured so that two adjacent ones maintain the same distance from each other, so that when the catch pieces (112) are assembled to the headliner, they are evenly deformed and then returned to their original state, so that the external force is not concentrated on one side, and can be evenly distributed and absorbed. In the drawing, the catch pieces (112) are exemplarily shown as two of them being formed in a row parallel to the pillar (112a).

3. Elastic section

The elastic pieces (113) are formed one on each side of the above-described base (111) with the catch piece (112) as the center, as shown in [Fig. 3] and [Fig. 4]. At this time, the elastic pieces (113) are inserted so that the catch piece (112) penetrates the headliner (H) and is assembled, so that the headliner (H) is positioned between the catch piece (112) and the elastic pieces (113), so that the elastic pieces (113) elastically support the headliner (H) and prevent a gap from being created, thereby preventing the assembly clip (110) from being easily detached or removed from the headliner (H).

As described above, the present invention not only eliminates the need to separately manufacture the assembly clip by integrally forming the assembly clip for forming the opening bracket, but also reduces the number of assembly clips, thereby reducing noise and joints while preventing them from easily detaching or separating, and also improving quality by preventing assembly clips from being unassembled at assembly points.
