Description

The present invention relates to the structure of a back door handle having a built-in camera.

The rear view camera was installed in vehicles such as large buses and trucks where the rear could not be seen from the driver's seat. In recent years, it has been increasingly installed in ordinary automobiles and light automobiles (hereinafter referred to as "automobiles, etc."). By displaying the image taken by the rear surveillance camera on the display device provided in the driver's seat, the driver can confirm the state behind the vehicle body.

In the case of automobiles, the design of the car body is an important factor for purchasing motivation. In many cases, the vehicle height itself is equal to or lower than that of a person. Therefore, attaching the rear surveillance camera to the outside leads to a situation in which the design is deteriorated and the possibility of theft increases.

Therefore, in automobiles and the like, it has been proposed to devise the installation position of the rear surveillance camera. With reference to FIG. 6, in Patent Document 1, in an automobile or the like having a back door 100 (FIG. 6A), a back in which a grip portion 114 and a back camera 116 are arranged on a main body of the back door handle 110. The door handle 110 (FIG. 6 (b)) is disclosed.

In the back door handle 110 of Patent Document 1, since the back camera 116 and the grip portion 114 of the back door handle 110 are arranged in parallel, there is a problem that the parts become large. Moreover, since the mounting portion of the back camera 116 is easily known, there is a possibility that the back camera 116 may be stolen.

The present invention has been conceived in view of the above problems, and provides a back door handle that does not increase in size by arranging a back camera and a back door handle grip portion (back door open / close switch) side by side in the front-rear direction of the vehicle body. It is a thing.

More specifically, the back door handle according to the present invention is
It is a back door handle that consists of two parts, an inner garnish and an outer garnish, and has a built-in back camera.

Further characterized that you have emblem disposed portion is formed to place the emblem.

In the back door handle according to the present invention, since the back camera and the back door open / close switch can be arranged in the front-rear direction in the vehicle body axial direction, the parts can be miniaturized.

It is a front view of the back door handle which concerns on this invention. It is a perspective view of the back door handle seen from the rear of the vehicle body. It is a perspective view of the back door handle seen from the front of the vehicle body. It is a mounting figure of a back door handle. It is sectional drawing of the back door handle attached to the back door. It is a figure which shows the conventional back door handle.

The back door handle and its structure according to the present invention will be described below with reference to the drawings. The following description exemplifies one embodiment of the present invention, and the present invention is not limited to the following description. Therefore, the following description can be modified without departing from the spirit of the present invention. In the present specification, the arrow Fr indicates the vehicle body front direction, and the arrow Rr indicates the vehicle body rear direction.

FIG. 1 shows a front view (a view seen from the rear of the vehicle body) of the back door handle 10 according to the present invention. In the following description, the case where the back door handle 10 is viewed from the rear of the vehicle body is referred to as "front (or front)". Therefore, "rear" means the case when viewed from the front of the vehicle body. In the back door handle 10, the outer garnish 12 is arranged on the back door outer panel 50. The outer garnish 12 is formed with an emblem arranging portion 16 for arranging the emblem and a grip portion 18. The back door itself is referred to as a back door 100.

The emblem arranging portion 16 is a flat portion to which the emblem is attached. A grip portion 18 is formed below the emblem arrangement portion 16. The grip portion 18 is a recess into which a finger or the like is inserted when opening and closing the back door 100.

2 and 3 show an exploded perspective view of the back door handle 10. FIG. 2 is a perspective view from the front (rear of the vehicle body) of the back door handle 10, and FIG. 3 is a perspective view from the rear (front of the vehicle body) of the back door handle 10. The main body of the back door handle 10 is composed of two parts, a resin outer garnish 12 and a resin inner garnish 14.

The inner garnish 14 is formed with a back door opening / closing switch mounting portion 22p and an inclined surface 14b on which the back camera mounting portion 20p is formed rearward. The back door opening / closing switch mounting portion 22p and the back camera mounting portion 20p are composed of a through hole 14hs, a through hole 14hc, a screw hole 22h, and a screw hole 20h provided on the rear inclined surface 14b of the inner garnish 14.

Side walls 14s are formed on both sides of the inner garnish 14, and the front 14f of the inner garnish 14 is open. An edge that opens to the front 14f side, and a part of the upper edge 14ue and the side edge 14se is formed on the same plane. The lower edge (lower edge 14de) is formed so as to recede rearward from this plane. Therefore, the lower edge 14de of the open edge is formed behind the upper edge 14ue (on the front side of the vehicle body). A receiving hole 14R for fitting a claw is formed on the open edge.

The back door opening / closing switch mounting portion 22p and the back camera mounting portion 20p are arranged at substantially the same positions in the vehicle body width direction. The back door opening / closing switch mounting portion 22p is located below the back camera mounting portion 20p and is formed forward in the front-rear direction of the vehicle body. Screw holes 22h for attaching the back door opening / closing switch 22 to the inner garnish 14 are formed on both sides of the back door opening / closing switch mounting portion 22p.

Screw holes 20h are also formed on both sides of the back camera mounting portion 20p. The inner garnish 14 is provided with reinforcing ribs and a thickness (not shown) so as to have sufficient strength to attach the back door opening / closing switch 22 and the back camera 20.

As described above, the outer garnish 12 is provided with a grip portion 18 below the emblem arranging portion 16. The grip portion 18 has a concave shape recessed rearward from the emblem arrangement portion 16. The recessed shape is formed by a ceiling surface 18u, a bottom surface 18b, a side surface 18s, and a back surface 18t. Each surface may be connected by a gentle curved surface.

Two openings, an opening 20o for a back camera and an opening 22o for a back door open / close switch, are formed on the recessed ceiling surface 18u. These openings substantially coincide with each other in the vehicle width direction and are formed side by side in the vehicle body front-rear direction. The back camera opening 20o is arranged on the front side (rear side of the vehicle body) of the back door open / close switch opening 22o.

Further, the back camera opening 20o is an opening in which only the lens of the back camera 20 is exposed, and the back door opening / closing switch opening 22o is an opening in which only the operation portion 22a of the back door opening / closing switch 22 is exposed. The recessed portion is formed narrower than the peripheral edge 12e of the outer garnish 12. That is, a flange-shaped portion is formed on the peripheral edge 12e of the outer garnish 12. This is an area for arranging the seal member 13 (see FIG. 5), which will be described later.

Further, the outer garnish 12 is provided with a claw 12n for fitting the claw with the inner garnish 14. The receiving hole 14R that fits with the claw 12n is provided on the inner garnish 14 side.

Next, attachment of the back door handle 10 will be described. See FIG. A back door inner panel 52 is arranged on the back side (front side of the vehicle body) of the back door outer panel 50. The back door outer panel 50 is formed with a back door handle mounting opening 50h that is bent at the lower side by cutting the upper side and the lateral side while leaving the lower side, instead of the recess formed by sheet metal press molding. Therefore, the tongue plate 50b may be attached to the back door handle mounting opening 50h.

In this way, by providing the back door handle mounting opening 50h for the back door handle on the back door outer panel 50, the depth space of the back door handle 10 can be secured. The back door inner panel 52 is provided with an opening 52h into which the inner garnish 14 fits.

The inner garnish 14 is fitted into the opening 52h provided in the back door inner panel 52 from the outside of the vehicle body. At this time, it is desirable that the back door opening / closing switch 22 and the back camera 20 are already attached to the inner garnish 14. The inner garnish 14 can be screwed to the back door inner panel 52 from the outside of the vehicle body.

That is, since the fastening work from the inside of the vehicle is not required, the dedicated process for attaching the back door handle 10 is not required. Further, since no parts for fastening are required on the back side of the back door inner panel 52, the structure of the back door inner panel 52 is also simplified.

Finally, the outer garnish 12 is pressed against the inner garnish 14 from the back door handle mounting opening 50h provided on the back door outer panel 50, and is fixed by claw fitting with the inner garnish 14. At this time, the seal member 13 (see FIG. 5) is arranged in the flange-shaped region around the inside of the outer garnish 12. The outer garnish 12 closes all the back door handle mounting openings 50h provided on the back door outer panel 50. Therefore, the outer garnish 12 covers all the inner garnish 14.

FIG. 5 shows a cross-sectional view of the back door handle 10 attached to the back door 100. The inner garnish 14 is fastened to the back door inner panel 52. The outer garnish 12 is fixed to the inner garnish 14 by claw fitting. Therefore, the outer garnish 12 cannot be removed from the outside of the vehicle without destroying it. A seal member 13 is arranged between the outer garnish 12 and the back door outer panel 50.

Only the operation portion 22a of the back door open / close switch 22 is exposed from the back door open / close switch opening 22o provided on the ceiling surface 18u of the recessed portion of the outer garnish 12. As for the back camera 20, only the lens 20L is exposed from the back camera opening 20o provided on the ceiling surface 18u. That is, the back camera opening 20o and the back door open / close switch opening 22o are arranged in the vehicle body front-rear direction (front-rear direction in side view).

By arranging in this way, the area of the back door handle 10 on the surface of the back door outer panel 50 can be made smaller than that in the case where the back camera 20 is arranged side by side with the back door opening / closing switch 22. Further, since only the lens 20L of the back camera 20 is exposed, it is difficult to discriminate and it is difficult to approach from the outside of the vehicle, so that the anti-theft performance is improved.

Further, since the outer garnish 12 has the emblem arranging portion 16, the space for attaching the emblem does not have to be provided in another area of the back door outer panel 50. That is, in the case of a design in which the lamp is attached to the back door 100, the degree of freedom in design can be increased.

The back door handle 10 according to the present invention forms a relatively large back door handle mounting opening 50h in the back door outer panel 50 for mounting the back door handle 10 (see FIG. 4). However, the outer garnish 12 is provided with a bag-shaped recessed portion (grip portion 18) below the flat emblem arranging portion 16. Since the grip portion 18 has a recessed container-like structure, it has high strength even though it is made of resin. Therefore, the outer garnish 12 functions as a part of the structural surface of the back door outer panel 50.

That is, even if the back door handle mounting opening 50h is provided, the strength of the back door outer panel 50 does not decrease. This means that the rigidity of the back door outer panel 50 is secured, and the depth space for the back door handle 10 is secured.

The present invention can be suitably used for a back door handle of an automobile or the like having a back door.
