DESCRIPTION OF SPECIFIC EMBODIMENTS

(9) Hereinafter, embodiments of the present disclosure are described in detail with reference to the accompanying drawings. However, in the following description and the accompanying drawings, a detailed description of well-known functions or configurations that can obscure the subject of the present disclosure have been omitted. In addition, it should be noted that the same components are denoted by the same reference numerals as much as possible throughout the drawings.

(10) Hereinafter, a tailgate guide bumper of a vehicle according to the present disclosure is described in detail with reference to the accompanying drawings.

(11) A tailgate guide bumper of a vehicle according to the present disclosure is installed between a tailgate 12 configured to be opened to the rear of a vehicle 1 and a vehicle body 11 of the vehicle 1 to support the tailgate 12 in a widthwise direction of the vehicle 1. The tailgate guide bumper includes a guide bumper member 21 fastened to one side of the tailgate 12 and a guide bumper supporting part 13aa configured to be in contact with the guide bumper member 21 when the tailgate 12 is closed to support load applied in a widthwise direction of the tailgate 12. In this example, the guide bumper member 21 and the guide bumper supporting part 13aa are installed to be adjacent to a lamp 13 installed at a rear side of the vehicle.

(12) The guide bumper member 21 is installed on a side surface of the tailgate 12.

(13) When the tailgate 12 is closed, the guide bumper member 21 is interposed between the tailgate 12 and the vehicle body to prevent the tailgate 12 from being moved.

(14) The guide bumper member 21 is formed to have a predetermined volume and is installed on the side surface of the tailgate 12. In particular, the guide bumper member 21 is fastened to an inner panel 12a of the tailgate 12.

(15) When the guide bumper member 21 is fastened to the inner panel 12a, the guide bumper member 21 is fastened to the inner panel 12a by using a fastening bolt 22. The guide bumper member 21 is mounted at a central portion thereof in a one-point manner by using the one fastening bolt 22 (see FIG. 6). Since the guide bumper member 21 is mounted at one point, the number of components required for an assembly process is reduced. This reduces a weight of the tailgate guide bumper and the man-hours required for an assembly process.

(16) When the tailgate 12 is closed, the guide bumper supporting part 13aa becomes in contact with the guide bumper member 21 to support both ends of the tailgate 12 (see FIG. 8).

(17) The guide bumper supporting part 13aa is integrally formed with a lamp housing 13a and the guide bumper member 21 is configured to be in contact with the guide bumper supporting part 13aa. Thus, the guide bumper member 21 is installed at an intermediate portion of the tailgate 12.

(18) In the prior art, the guide bumper is installed on the lower end of the tailgate 112. However, in the present disclosure, since the guide bumper supporting part 13aa is integrally formed with the lamp housing 13a, the guide bumper member 21 is installed at the intermediate portion of the tailgate 12. The intermediate portion of the tailgate 12 is a point at which the load applied to the tailgate 12 becomes maximum when the vehicle 1 is being driven. In the present disclosure, the guide bumper member 21 and the guide bumper supporting part 13aa are installed on this portion.

(19) The guide bumper supporting part 13aa is installed on a portion at a predetermined height from the lower end of the tailgate 12, i.e., on a portion on which the rear combination lamp 13 is installed. In particular, the guide bumper supporting part 13aa is formed to be extended from the lamp housing 13a, which corresponds to the vehicle body, of the lamp 13 provided at the rear side of the vehicle body. The lamp housing 13a corresponds to the vehicle body and a lamp housing 13b corresponds to the tailgate 12. In other words, as illustrated in FIG. 7, the guide bumper supporting part 13aa is formed to be extended from the lamp housing 13a, which is positioned inside an extension panel 11b constituting the vehicle body, towards a side outer panel 11a. The guide bumper supporting part 13aa is formed to be extended from the lamp housing 13a towards the side outer panel 11a in a state in which it is spaced apart from the extension panel 11b. The guide bumper supporting part 13aa is formed to allow an end portion 15 thereof to be adjacent to the side outer panel 11a.

(20) In order to fasten the guide bumper supporting part 13aa to the vehicle body side, i.e., to the extension panel 11b, the guide bumper supporting part 13aa is fastened to the extension panel 11b with the fastening bolt 14. A direction in which the fastening bolts 14 is fastened is allowed to approximately coincide with a widthwise direction (direction L) of the vehicle. A mounting direction M of the fastening bolt 14 is similar to an applied load direction V in which load is applied when the vehicle is travelling. Thus, an additional reinforcing member for securing rigidity of a portion to which the fastening bolt 14 is fastened is not necessary.

(21) In particular, the fastening bolt 14 is mounted on a center of the guide bumper supporting part 13aa in the one-point manner (see FIG. 5). In the prior art, the guide bumper member is fastened with a plurality of fastening bolts. In the present disclosure, however, the guide bumper supporting part 13aa is fastened with only one fastening bolt 14. Thus, the weight of the tailgate guide bumper and the man-hours required for the assembly process are reduced.

(22) The guide bumper supporting part 13aa may be formed from a plastic material, such as polycarbonate-acrylonitrile butadiene styrene (PC-ABS). PC-ABS is a composite material of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) and is one of a number engineered thermoplastic resins having high impact resistance. By manufacturing the guide bumper supporting part 13aa using PC-ABS as a raw material, even if the load is repeatedly applied to the guide bumper supporting part 13aa when the tailgate 12 is closed, the guide bumper supporting part can support the tailgate 12.

(23) Meanwhile, the guide bumper member 21 is made of a rubber material and a steel material. In one example, the rubber material is thermoplastic elastomer (TPE). For example, the guide bumper member 21 may be manufactured by injection molding TPE in a state in which steel is insert molded into the TPE part. TPE can be molded like a plastic, which becomes flexible at a high temperature, and is a polymeric material, which exhibits properties of elastomer at room temperature. Since TPE is employed as the raw material of the guide bumper member 21, in a case where the tailgate 12 is being closed, when the guide bumper member 21 is in contact with the guide bumper supporting part 13aa, shock is absorbed by the guide bumper member 21, thereby reducing noise. In addition, in a state in which the tailgate 12 is closed, the guide bumper member 21 is kept in contact with the guide bumper supporting part 13aa. The guide bumper member 21, which is an elastic body, absorbs the load applied, when the vehicle 1 is being driven, in the widthwise direction of the tailgate 12, thereby reducing shifting movements of the tailgate 12 in the widthwise direction.

(24) Reference numerals 12b and 12c, which are not described above, represent a tailgate outer panel constituting the tailgate 12 and a gas cylinder provided to support the tailgate 12 when the tailgate 12 is opened, respectively.

(25) According to the tailgate guide bumper of the vehicle of the present disclosure having the above-described structure, by employing a part of the lamp housing as the guide bumper, the inconvenience of fastening the members of the guide bumper to the vehicle body and the tailgate, respectively, is eliminated.

(26) Further, the portion where the guide bumper is installed is located at the intermediate portion of the tailgate to match the portion or location where the load is most greatly applied in the direction L when the vehicle is travelling with the portion or location where the guide bumper is installed, so that movement of the tailgate is significantly reduced.

(27) Although the embodiments have been described with a focus on novel features of the present disclosure applied to the various embodiments, it will be apparent to those of ordinary skill in the art that various deletions, substitutions, and changes in the form and details of the apparatus and method described above may be made without departing from the scope of the present disclosure. Accordingly, the scope of the present disclosure is defined by the appended claims rather than by the foregoing description. All modifications within the equivalent scope of the appended claims are embraced within the scope of the present disclosure.
