Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a door handle for an automobile, in which the sealing performance of an end cover is improved.

2. Description of the Related Art Generally, in a vehicle door handle, a handle body that is manually operated when getting on and off is rotatably supported by a bracket called an escutcheon, and the bracket is fastened and fixed to a door panel with an end cover as a seat.

Both the handle body and the bracket are generally molded products made of metal such as zinc or molded products made of synthetic resin such as polyacetal resin. The end cover is made of synthetic resin such as polypropylene, butadiene styrene rubber,
It is molded from synthetic rubber such as butadiene acrylonitrile rubber and polychloroprene. The end cover has a packing function that relieves impact force applied by the turning operation of the handle body and at the same time secures a sealing property with respect to rainwater and washing water from the outside with the door panel.

Therefore, the sealing property between the bracket and the end cover,
It is necessary to ensure the sealability between the end cover and the door panel side, and conventionally, a structure is adopted in which a protrusion is formed on the back surface of the bracket and the protrusion enhances the adhesion with the end cover. . Further, the end cover is provided with a lip that is folded back in a brim shape on the entire peripheral edge thereof, and the lip absorbs a gap with the surface of the door panel.

As a door handle with such a seal structure,
For example, there is a pad for a vehicle outside door handle described in Japanese Utility Model Laid-Open No. 59-15548.

However, in the case of the conventional structure in which the protrusion is formed on the back surface of the bracket, since the bracket is a hard material made of metal or hard synthetic resin, the protrusion causes excessive force on the door panel at the assembly stage. May cause the door panel to be distorted.

Further, in the structure of Japanese Utility Model Laid-Open No. 59-15548, the length of the contact peripheral portion formed on the pad is long, and the contact peripheral portion of the pad itself warps backward due to the tightening force at the time of assembly, so Cannot absorb the gap between them uniformly,
It is difficult to secure sufficient sealability.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automobile door handle improved in sealing ability against rainwater and washing water and preventing the excessive force of the door panel from being applied by the tightening force during assembly.

An automobile door handle according to the present invention has a bracket that rotatably supports a handle body and is fixed to a door panel, and the bracket is fixed to the door panel via an end cover.

Lips are formed upright around the entire circumference of the end cover at an angle with respect to the main surface, and a plurality of projections that are elastically deformed by pressing force are formed at intervals at positions separated along the inner surface of the lip, The peripheral end of the bracket is in close contact with the lip and the projection is deformed to be flat so that the main surface of the end cover is in close contact with the door panel.

When the engine cover is joined to the back of the bracket by assembly, the peripheral edge of the bracket comes into close contact with the lip of the end cover. Further, due to the tightening force, the projection of the end cover is elastically crushed and deformed by the peripheral end of the bracket, and the deformation of the projection absorbs the gap between the projection and the door panel.

By deforming the protrusions of the end cover flatly, the gap is reduced and the required sealing performance is secured, and the tightening force that acts on the door panel is elastically absorbed, so excessive force is applied to the door panel. It does not work, and the occurrence of distortion can be avoided.

Embodiment Hereinafter, an embodiment of an automobile door handle according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 6, the door handle is joined to a handle body 10, a bracket 20 that rotatably supports the handle body 10 and is generally called an escutcheon, and a rear surface of the bracket 20. An end cover 30 as a packing member is used as a main member. What is made into a part as a door handle by each of these members is attached to the door panel 40 via the end cover 30.
The mounting is fastened to the door panel 40 with a nut via the stud bolts 23, 23 raised on the back surface of the bracket 20.

Both the handle body 10 and the bracket 20 are generally molded products made of metal such as zinc or molded products made of synthetic resin such as polyacetal resin. A pair of arm portions 11 and 11 on both sides are provided on the rear surface of the handle body 10, and a pair of arm portions 21 and 21 are also provided on the left and right sides of the rear surface on the bracket 20 side. The shaft 22 is inserted through the arm portions 11 and 21 of these two members by tying them together, and the handle body 10 is rotatably supported by the bracket 20. To prevent the arms 11 of the handle body 10 from interfering with each other when rotating, the bracket 20
Insertion windows of the arm portions 11, 11 are opened in the. A spring 25 is elastically attached around the axis of the shaft 22, and the handle body 10 is manually operated from a fixed position to the front against the spring 25.

Further, the end cover 30 is made of synthetic resin such as polypropylene,
It is molded from synthetic rubber such as butadiene styrene rubber, butadiene acrylonitrile rubber, and polychloroprene. The elasticity of the material is used to absorb the shock when the handle body 10 is rotated against the spring member and to secure a sealing property with the door panel 40 against rainwater and washing water. Have.

As is apparent from FIGS. 5 and 6, a lip 32 is formed by folding back around the main body 31 of the end cover 30 in a direction substantially perpendicular to the main surface 33a. A fitting groove 33 is formed in the. The peripheral edge of the bracket 20 is fitted into the fitting groove 33. Also, in the fitting groove 33, the lip 32
A pyramidal protrusion 34 is provided at a position away from the inner surface of the
A plurality of protrusions 34 are arranged at arbitrary intervals over the entire circumference of the end cover 30.

As shown in the figure, the protrusion 34 is arranged with its longitudinal direction oriented substantially at a right angle to the lip 32, but the longitudinal direction may be arranged parallel to the inner surface of the lip 32.

Next, the operation of the above-described embodiment is performed when the end cover is attached to the door panel 40 of the door handle that is made into parts.
30 is interposed between the bracket 20 and the door panel 40.
When the bracket 20 is fastened to the door panel 40, the peripheral edge portion of the bracket 20 is fitted into the fitting groove 33 of the end cover 30 and is brought into close contact with the lip 32. Also, depending on the tightening force,
The protrusion 34 is elastically deformed and crushed at the peripheral end portion of the bracket 20, and the gap h between the peripheral end surface of the bracket 20 and the surface of the door panel 40 is absorbed. That is, due to the elastic deformation of the protrusion 34, the lip 32 and the main surface 33a with respect to the door panel 40.
With a sufficient pressing force, evenly adheres over the entire peripheral edge portion, so that the required sealing property is secured. At the same time, the protrusion 34 prevents the door panel 40 from being deformed due to the pressing of the bracket 20.

FIG. 7 shows a modification of the protrusion 34 of the above embodiment. The protrusion 36 is different from the pyramidal shape of the protrusion 34 in the above-described embodiment, and the protrusion 36 in which the bottom surface of the fitting groove 33 is partially protruded has the same elastic deformation, action, and operation as the protrusion 34 in the above-described embodiment. The effect can occur.

As for the shape of the protrusion 34, various shapes such as a columnar shape, a cylindrical shape, a fin shape, etc. can be adopted in addition to the mountain shape as described above.

Effect of the Invention As described above, in the vehicle door handle according to the present invention, the protrusion of the end cover is elastically pressed and deformed by the peripheral end of the bracket due to the tightening force during assembly. By deforming the protrusions of the end cover flatly, the gap is reduced and the required sealing performance is secured, and the tightening force that acts on the door panel is elastically absorbed, so excessive force is applied to the door panel. Does not work, and has the effect of avoiding the occurrence of distortion.
