Abstract

PURPOSE: An inner handle assembly structure for motor vehicle is provided to reduce assembly procedures and cost and improve productivity by forming a grommet integrally with the inner handle. CONSTITUTION: An inner panel(10) of a door has a handle mounting recess(11) formed at the inner surface of the inner panel so as to mount an inner handle(20) into the handle mounting recess which has a square assembly hole(12) formed at the bottom surface of the handle mounting recess. The inner handle has a body(21), and a square grommet(22) elastically caught at the assembly hole formed at the recess of the inner panel is protruded from an outer surface of the body of the inner handle. The grommet is formed integrally with the body of the inner handle. The grommet is formed of two inserted sections(24) divided by a cut section(23) formed in an axial direction, and each inserted section has a fixing groove(25) for insertion of the edge of the recess of the inner panel. The grommet has a coupling hole(26) formed at the center of the grommet in such a manner as to penetrate through the body of the inner handle. The coupling hole has a diameter smaller than a screw(30), such that the coupling hole is elastically transformed outward during coupling of the screw.

Description

Inner handle assembly structure of vehicle {a structure for assembling inner handle of vehicle}

The present invention relates to a door of a vehicle, and more particularly, to a structure for assembling an inner handle for opening and closing the door.

In general, a vehicle is provided with a plurality of doors so that a passenger, such as a driver, can get in and out of the room, and each door has a door lock device for locking the door to the vehicle body. Accordingly, an outer and inner handle for releasing the door lock device is provided at the inside and the outside of the door so that the door can be opened at the time of getting on and off.

1 schematically shows a conventional structure for assembling a double inner handle 1 to a door 2. This forms a square hole 4 in the bottom of the handle seating groove 3 formed in the inner panel 2 of the door and fits the synthetic resin grommets 5 thereon. Then, the two fitting portions 5a of the grammets 5 are elastically deformed inward, and then returned to their initial state, so that the edge portions of the square holes 4 are flanged 5b and the fitting portions 5a of the gradients 5. The grommet 5 is fixed to the inner panel 3 by being fitted in the fixing groove 6 formed therebetween. Subsequently, the fastening holes 1a and 7 of the inner handle 1 and the grammets 5 are matched with each other, and then a screw 8 is inserted into each of the assembling holes 1a and 7 from the inner handle 1 side. The inner handle 1 is assembled to the door 2 by fastening.

However, since the conventional inner handle assembly structure uses a separate grits 5, not only the assembly labor is increased but also a cost increase factor due to the grits 5 occurs, and the inner handles are tightened even when the screw 8 is fastened. Since the fastening holes 1a and 7 of (1) and the grammant 5 should coincide with each other, there is a problem in that the assembly performance is lowered.

The present invention has been made in view of the above-described conventional problems, and the inner handle assembly structure of the vehicle which can facilitate assembly labor and cost reduction and assemblability by simply assembling the inner handle to the door without a separate gradation The purpose is to provide

20: Inner Handle 22: Grammar (inner handle)

24: fitting part of grammit 25: fixing groove

26: fastening hole 30 of the screw

In order to achieve the above object, the inner handle assembly structure of the vehicle according to the present invention forms a handle seating groove having a square assembling hole in the inner panel of the door, and the inner body of the inner handle inserted into the handle seating groove. It is characterized in that the angular gradation which is elastically fitted in the assembly hole of the panel is integrally formed to protrude, and at the same time, a fastening hole is formed in the gradation to fasten the screw thereto.

Accordingly, the present invention, since the inner handle can be assembled to the door by simply inserting the gramm of the inner handle into the assembly hole of the inner panel and then fastening the screw, it is effective to reduce the labor and cost of assembly of the door and improve the assemblability. Will be exercised.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

2 and 3, the inner handle assembly structure of the vehicle according to the present invention has a handle seating groove 11 for mounting the inner handle 20 on the inner surface of the inner panel 10 of the door as in the conventional inner handle assembly And a rectangular assembling hole 12 is formed in the bottom surface of the handle seating groove 11.

In addition, the outer surface of the body 21 of the inner handle 20 is formed so that the rectangular gram 22, which is elastically fitted into the assembly hole 12 of the inner panel 10, protrudes according to the characteristics of the present invention. The grommet 22 is integrally molded at the time of forming the inner handle 20 body 21. Grammar 22 is composed of two fitting portions 24 having elasticity by the cutting portion 23 formed in the axial direction, the assembly hole of the inner panel 10 on the outer surface of the fixed end of each fitting portion ( 13) a fixing groove 25 for inserting the edge portion is formed.

In addition, a fastening hole 26 for fastening the screw 30 is formed to penetrate the body 21 of the inner handle 20 at the center of the grommet 22, and the fastening hole 26 is a screw 30. ) Is preferably formed with a diameter smaller than the screw 30 so as to be elastically deformed outwards.

The remaining reference numeral 27 is a lever of the inner handle 20.

In the inner handle assembly structure of the vehicle according to the present invention having such a structural feature, first insert the grommet 22 of the inner handle 20 into the assembly hole 12 of the inner panel 10. Then, the two fitting portions 24 of the gramm 22 are elastically deformed inwardly by the ablation portion 23 and then restored to their initial state, and thus the edges of the assembly holes 12 of the inner panel 10 The inner handle 20 is mounted to the inner panel 10 of the door 10 by being inserted into the fixing groove 25 of the met 22.

In this state, the screw 30 is fastened to the fastening hole 26 of the gram | 22. Then, the two fitting portions 24 of the gramm 22 are further opened to the outside by the screw 30, so that the gramm 22 is strongly pressed into the assembly holes 12 of the inner panel 10. As a result, the inner handle 20 is firmly assembled to the door 10.

As described above, according to the present invention, since the grommet is formed integrally with the inner handle, the inner handle is assembled by simply inserting the inner handle directly into the assembly hole of the inner panel and then fastening the screw to the fastening hole of the grammet. Will be able to complete. In addition, there is no need to match the fastening holes of the inner handle and the gramm with each other as in the prior art, which makes assembly work much easier.

Therefore, the present invention can contribute to the assembly labor and cost reduction of the vehicle door, as well as has an excellent effect to improve the assembly.
