Description

Inner side plate structure of vehicle rear baffle

Technical Field

The present invention relates to an inner panel structure of a tailgate for a vehicle.

Background

Generally, in vehicles of the SUV, station wagon, or the like, a hatchback opening and closing Tailgate (Tailgate) is used. The rear flap is configured to pivot up and down about a hinge structure at the top to open and close the luggage compartment, so that a relatively large space of the luggage compartment can be opened, and thus, its application has been increasing in recent years.

The tailgate is fabricated substantially divided into an outer side panel and an inner side panel. Generally, the outer panel and the inner panel are formed by pressing a steel plate, and are bonded by spot welding or the like to form a tailgate. For example, in laid-open patent No. 10-2012 and 0033752, a method of forming such a tailgate inner side (inner side plate) by a press working is disclosed.

However, in recent years, in the related art, weight reduction of vehicles and further diversification of materials are beginning to be focused, which also causes the tailgate to be developed using more lightweight materials. Among them, one that is being developed is a tailgate that partially or entirely employs a plastic material. Compared with the traditional steel, the rear baffle made of the plastic material has the advantages of obviously reduced weight and strong corrosion resistance. In addition, there are advantages in that molding is relatively easy and the degree of freedom in design is high.

However, the above-mentioned plastic tailgate is less rigid than steel, and may suffer from warpage, deformation, and reduction in rigidity during assembly or in environmental testing, and thus, needs to be improved.

It should be understood that the following examples are intended to aid in the understanding of the present invention, but the scope of the present invention is not limited to the following examples. The following embodiments are intended to more fully describe the technical gist of the present invention to those skilled in the art, and a detailed description of known structures will be omitted when it is judged that the technical gist of the present invention may be unnecessarily made.

Referring to fig. 1, an inner side panel structure (hereinafter, referred to as "inner side panel structure 100") of a tailgate for a vehicle according to the present embodiment may include a panel body 110.

The plate body 110 may form an overall appearance of the inner decking structure 100. However, the plate body 110 may also be appropriately changed according to the design shape of the tailgate or the like and is not necessarily limited to the illustrated shape.

The plate body 110 may partially or entirely comprise a plastic material. Preferably, the plate body 110 is made of plastic as the main material. In the present embodiment, the plate body 110 is intended to be plastic injection molded in the shape shown in the drawings.

It is known that the use of plastic materials has the advantage of a considerable weight reduction and a strong corrosion resistance compared to steel (steel). In addition, the molding is relatively easy, and the degree of freedom of design can be increased.

On the other hand, the illustrated inner plate structures 100 to 110 may be assembled with a predetermined outer plate. The main surface (main surface) shown in fig. 1 shows the surface assembled with the outer plate. Therefore, first to fourth adhesive ribs 160 to 190, etc., which will be described later, may be disposed between the inner panel structure 100 and the outer panel. Part or all of the outer panel may comprise a plastics material, and in general may be made of a plastics material as the primary material.

On the other hand, the inner decking structure 100 according to this embodiment may include a rear glass mounting space 120.

The rear glass installation space 120 may provide a space for installing a rear glass provided on the tailgate. The rear glass attachment space 120 may be formed in the shape of an opening portion corresponding to the size, shape, and the like of the rear glass. The rear glass mounting space 120 is formed to extend substantially in the upper region of the body 110, having a prescribed width and height. Which corresponds to the size, shape, etc. of a general rear glass.

On the other hand, the inner decking structure 100 according to the present embodiment may include an elevator installation part 130.

The lifter installation parts 130 may be formed in a pair on both left and right sides of the plate body 110. Specifically, the lifter installation parts 130 may be in a pair at left and right end portions of the plate body 110 below the rear glass installation space 120. The lifter installation part 130 may be disposed substantially at the upper and lower center portions of the plate body 110.

The lifter installation part 130 may be installed with a lifter for assisting the opening and closing of the tailgate. One side of the lifter may be installed at a vehicle body side adjacent to the tailgate, and the other side may be installed at the tailgate after fastening the lifter installation part 130. The riser mount 130 may include a prescribed structure, shape, etc. for coupling the riser.

On the other hand, the inner panel structure 100 according to the present embodiment may include a wiper motor mount 140.

The wiper motor mounting part 140 may be disposed at a left and right central portion of the body 110 below the rear glass mounting space 120. The wiper motor mount 140 may provide a mounting space for a wiper motor driving the rear wiper. The wiper motor mounting part 140 may be formed in a predetermined size, shape, and the like according to the size, shape, and the like of the wiper motor. The wiper motor mounting portion 140 may have a predetermined width and height in the left and right direction substantially around the center of the plate body 110. As shown, the wiper motor mounting portion 140 is generally rectangular in outline, having a prescribed left-right width and height.

On the other hand, the inner side plate structure 100 according to the present embodiment may include a latch mounting portion 150.

The latch mounting portion 150 may be provided at a bottom region of the plate body 110. Specifically, the latches 150 are arranged below the wiper motor mounting portion 140 at the left and right center of the body 110 at a predetermined interval. The latch mounting portion 150 may be disposed substantially adjacent to a lower end portion of the plate body 110. A tailgate latch for locking the tailgate may be mounted to the latch mounting 150.

On the other hand, the inner side panel structure 100 of the present embodiment may further include first to fourth adhesive ribs 160 to 190.

The first through fourth adhesive ribs 160 through 190 may provide an adhesive structure between the inner panel structure 100 and the outer panel. That is, the inner panel structure 100 may be bonded to the outer panel at a position including the first through fourth bonding ribs 160 through 190, forming a tailgate.

In addition, the first to fourth adhesive ribs 160 to 190 may complement the rigidity of the plate body 110. The inner panel structure 100 according to the present embodiment is made of plastic material to form part or all of the panel body 110, so as to prevent the problems of warpage, deformation, and rigidity reduction during the assembly process or environmental test. Here, the inner panel structure 100 according to the present embodiment can maximize the effect of complementing rigidity by disposing the specific first to fourth adhesive ribs 160 to 190.

Fig. 2 is a partially enlarged view of fig. 1.

Referring to fig. 1 and 2, a pair of first adhesive ribs 160 may be disposed on the plate body 110 to be spaced apart from each other in the left-right direction with the wiper motor mounting part 140 interposed therebetween.

Preferably, the pair of first adhesive ribs 160 may be disposed on the first imaginary line L1. Here, the first virtual line L1 is a virtual line connecting the left and right lifter installation parts 130. Therefore, the first adhesive rib 160 can appropriately support deformation and the like of the tailgate with respect to the load applied to the lifter installation part 130.

In addition, the first imaginary line L1 may be approximately trisected by the pair of first adhesive ribs 160. That is, the pair of adhesive ribs 160 may be arranged corresponding to each division position that trisects the first virtual line L1. This is to ensure that the rigidity can be uniformly enhanced in the right-left direction of the plate body 110.

The first adhesive rib 160 may be formed to protrude the plate body 110 by a prescribed degree, and may be injection-molded integrally with the plate body 110. In addition, the first adhesive rib 160 may extend to the left and right along the first imaginary line L1 to form a prescribed length. Preferably, each of the first adhesive ribs 160 may have a length of about 5 to 10% compared to a left-right interval of the lifter installation part 130.

On the other hand, the second adhesive rib 170 may be disposed below the first adhesive rib 160 with a predetermined distance therebetween. The second adhesive ribs 170 may be provided in a pair, and the pair of second adhesive ribs 170 may be disposed on the plate body 110 at a left-right interval.

The second adhesive rib 170 may be disposed on the second imaginary line L2. The second virtual line L2 is a virtual line extending from one side lower end of the plate body 110 to the center of the wiper motor mounting portion 140. The second imaginary lines L2 may be a pair as shown in fig. 1, extending from each side end of the plate body 110 to both left and right ends of the wiper motor mounting portion 140 at the center. The second adhesive rib 170 may be disposed on the plate body 110 such that the left and right center portions are substantially located on the second imaginary line L2.

In addition, the second imaginary line L2 may be approximately bisected by its contact point with the second adhesive rib 170. That is, the distance from one end of the second imaginary line L2 to the contact point thereof with the second adhesive rib 170 may be formed to be equal to or correspond to the distance from the above contact point to the other end of the second imaginary line L2.

The left-right width of the second adhesive rib 170 may be formed to be greater than the left-right width of the first adhesive rib 160 by a prescribed degree. That is, when the left and right width of the first adhesive rib 160 refers to the first width W1 and the left and right width of the second adhesive rib 170 refers to the second width W2, the second width W2 may be formed to be greater than the first width W1 by a prescribed degree. Preferably, the second width W2 may be formed to be 1.5 to 2 times the first width W1. In view of ensuring sufficient rigidity, the second adhesive rib 170 is disposed at a central portion of the bottom structure of the plate body 110 excluding the rear glass installation space 120.

On the other hand, the third adhesive rib 180 may be disposed above the second adhesive rib 170. The third adhesive rib 180 may be disposed at a position lower than the first adhesive rib 160 or the first imaginary line L1 by a predetermined degree or at a position higher than the second adhesive rib 170 by a predetermined degree. Preferably, the third adhesive rib 180 is disposed above the second adhesive rib 170 with a predetermined interval therebetween, and is disposed at a position slightly lower than the first adhesive rib 160 or the first virtual line L1. Which substantially corresponds to a lower end edge portion of the wiper motor mounting part 140.

The third adhesive ribs 180 may be paired on both left and right sides, and the pair of third adhesive ribs 180 may be disposed at left and right intervals to correspond to the lower end edge position of the wiper motor mounting part 140. The pair of third adhesive ribs 180 may be disposed substantially inside the pair of first adhesive ribs 160. Therefore, the left-right spacing between the pair of third bonding ribs 180 may be formed to be smaller than the left-right spacing between the first bonding ribs 160 by a prescribed degree.

The third adhesive rib 180 may have a prescribed left-right width. Here, when the left and right width of the third adhesive rib 180 refers to the third width W3, the third width W3 may be formed to be smaller than the first width W1 by a prescribed degree. Preferably, the third width W3 may be formed to be 30-70% of the first width W1. It is considered that the partial rigidity of the corresponding portion can be assisted by the wiper motor mounting portion 140, and the partial rigidity can also be assisted by the pair of first adhesive ribs 160 disposed on the left and right.

The third adhesive rib 180 as described above may be disposed at a contact point where the first and second imaginary lines L1, L2 meet and between the first and second imaginary lines L1, L2. Therefore, the third adhesive rib 180 may have a function of enhancing the rigidity of the wiper motor mount 140 and complementing the rigidity of the first and second

adhesive ribs

160, 170.

On the other hand, the fourth adhesive ribs 190 may be formed at left and right central portions of the pair of second adhesive ribs 170. Alternatively, the fourth adhesive ribs 190 may be formed at the left and right center positions of the plate body 110 at a height corresponding to the pair of second adhesive ribs 170.

The fourth adhesive rib 190 may enhance the rigidity of the latch mounting portion 150. That is, the fourth adhesive rib 190 may be disposed adjacent to the latch mounting portion 150 at a lower left and right center portion of the plate body 110 corresponding to the latch mounting portion 150.

When the left-right width of the fourth adhesive rib 190 refers to the fourth width W4, it may be formed to be equal to the second width W2 of the second adhesive rib 170 or to be greater than the second width W2 of the second adhesive rib 170 by a prescribed degree. Generally, a large external force is applied to the latch mounting portion 150, and therefore, this is done to ensure more sufficient rigidity.

In addition, the first to fourth bonding ribs 160 to 190 may have a prescribed vertical and horizontal width to secure a bonding area with the outer panel. In a specific embodiment, the first to fourth bonding ribs 160 to 190 may have bonding surfaces with a vertical height of about 8mm or more, the first and

third bonding ribs

160 and 180 may have bonding surfaces with a left-right width of about 20mm or more, and the second and

fourth bonding ribs

170 and 190 may have bonding surfaces with a left-right width of about 100mm or more.

On the other hand, although not shown, one or more reinforcing ribs for reinforcing rigidity may be further provided inside the first to fourth bonding ribs 160 to 190 as needed. The reinforcing ribs may be formed as an integral structure when the first to fourth bonding ribs 160 to 190 are injection-molded, and a plurality of reinforcing ribs may be arranged at left and right intervals according to the left and right widths, etc., of each of the first to fourth bonding ribs 160 to 190.

Referring to fig. 3, the first and third

adhesive ribs

160 and 180 may protrude from the plate body 110 to form a prescribed angle with respect to a reference line V in the vertical direction. Specifically, the first and third

adhesive ribs

160 and 180 may be protrudingly formed such that the bottom surface is at a first angle a1 with respect to a reference line V in the vertical direction. The first angle A1 may be an acute angle, and preferably, may be 30-60 degrees.

On the other hand, the second and

fourth bonding ribs

170 and 190 may be protrudingly formed such that the bottom surface is at a second angle a2 with respect to the reference line V of the vertical direction. The second angle may be an acute angle similar to the aforementioned first angle A1, and preferably, may be 30-60 degrees.

As described above, according to the inner panel structure 100 of the tailgate for a vehicle according to the embodiment of the present invention, it is possible to realize the technical advantages that can be achieved by using a plastic material, such as: reduced weight, corrosion resistance and easy forming.

In addition, according to the inner panel structure 100 of the tailgate according to the embodiment of the present invention, it is possible to secure sufficient structural rigidity even if a plastic material is used, by providing the pair of first adhesive ribs 160 disposed on the first virtual line L1, the pair of second adhesive ribs 170 disposed on the second virtual line L2, the pair of third adhesive ribs 180 disposed between the first and second virtual lines L1 and L2 at the lower end of the wiper motor mounting portion 140, and the fourth adhesive ribs 190 disposed at the left and right centers of the panel body 110 to enhance the rigidity of the latch mounting portion 150.

While the embodiments of the present invention have been described, it will be apparent to those skilled in the art that various modifications and changes may be made to the present invention by adding, modifying, deleting or adding components without departing from the scope of the inventive concept set forth in the claims.
