DETAILED DESCRIPTION
Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that the present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
As illustrated in FIGS. 3 to 7, a hole mounting device of a panel for a vehicle according to various embodiments of the present invention includes a vehicle body panel 10 provided with a plurality of holes and a base 100 disposed inside the vehicle body panel 10 and corresponding to the hole.
As illustrated in FIGS. 3 and 4, the vehicle body panel 10 is provided with the plurality of holes 1 and 2 through which parts may be mounted.
In this case, the vehicle body panel 10 may be earthed to secure safety of an operator or accurately operate working equipment at the time of performing various kinds of working. To this end, the vehicle body panel 10 and the earth terminal 30 are mounted.
According to various embodiments of the present invention, when the vehicle body panel 10 and the earth terminal 30 are mounted, the vehicle body panel 10 is provided with the base 100 to reduce a space between holes formed in the vehicle body panel 10 and holes formed in the earth terminal 30.
Meanwhile, the plurality of holes formed in the vehicle body panel 10 include a first hole 1 and a second hole 2.
As illustrated in FIGS. 6 and 7, the base 100 is basically disposed inside the vehicle body panel 10 and one end thereof is inserted into the first hole 1 of the vehicle body panel 10 and the other end thereof is fastened with the second hole 2 of the vehicle body panel 10 with a bolt B.
In this case, a protrusion 110 is protrudedly formed at one end of an upper surface of the base 100 and thus may be inserted into the first hole 1 of the vehicle body panel 10 and a fastening part 120 is formed at the other end of the upper surface thereof and thus may be mounted along with the bolt B inserted into the second hole 2 of the vehicle body panel 10.
In this configuration, the protrusion 110 formed in the base 100 is provided in a cylindrical shape, and as illustrated in FIG. 4, the first hole 1 of the vehicle body panel 10 into which the protrusion 110 is inserted is provided in a circular shape corresponding to an outer diameter of the protrusion 110 to prevent the space between the base 100 and the vehicle body panel 10 from occurring and as illustrated in FIGS. 6 and 7, the protrusion 110 penetrating through the first hole 1 may be inserted into a first through hole 31 formed in the earth terminal 30 to couple the base 100 with the vehicle body panel 10 and the earth terminal 30.
Meanwhile, the fastening part 120 is configured of a fastening hole 121 penetrately formed at the other end of the upper surface of the base 100 and a nut 122 integrally mounted on a lower surface of the other end of the base 100 provided with the fastening hole 121 and thus when the fastening part 120 is fastened with the bolt B inserted into the second hole 2 of the vehicle body panel 10, a separate nut 122 is disposed under the vehicle body panel 10 to solve a problem in that working convenience is degraded.
As the result, a second through hole 32 of the earth terminal 30 disposed on the vehicle body panel 10, the second hole 2 of the vehicle body panel 10, and the nut 122 of the base 100 are mounted through the bolt B.
Further, the upper surface of the base 100 on which the protrusion 110 and the fastening part 120 are formed is provided with a welding protrusion 130 to weld between the base 100 and the vehicle body panel 10 when the base 100 is coupled with the vehicle body panel 10, thereby preventing noise and exhaust gas from being introduced into a micro gap between the base 100 and the vehicle body panel 10.
As such, the present invention includes the vehicle body panel 10 provided with the plurality of holes and the base 100 of which one end is inserted into the first hole 1 of the vehicle body panel 10 and the other end is fastened with another hole of the vehicle body panel 10 with the bolt B, such that one end of the earth terminal is inserted through one base 100 and the other end thereof is fastened with the bolt B, thereby improving the working convenience, reducing the occurrence of the space of the hole mounting to improve the NVH performance of the vehicle and prevent the exhaust gas of the vehicle from being introduced into the vehicle interior, and minimizing the number of parts to remove the factors of rise in costs so as to improve the marketability.
