Japanese Unexamined Patent Publication No. 2002-322834

However, in the above-mentioned conventional example, since the operating member is exposed and arranged on the back surface of the grip portion of the handle body, there is a drawback that the operation member becomes inoperable when raindrops or the like adhere to it and freeze.

The present invention has been made to eliminate the above drawbacks, and an object of the present invention is to provide a steering wheel device for a vehicle capable of preventing an operation failure due to freezing or the like.

According to the present invention, the above object is
A handle body 3 having a protrusion 2 that holds the electronic component 1 and protrudes toward the back surface.
It has an operating member 4 that is externally fitted to the protruding portion 2 from the back surface direction and is freely moved and operated from an initial position where the fitting depth is shallow to an operating position where the fitting depth is deep and is connected to the handle body 3.
This is achieved by providing the protrusion 2 with a vehicle steering wheel device in which a drainage passage 5 that penetrates the protrusion 2 and communicates in the vertical direction is formed.

The handle device has a handle body 3 having a protrusion 2 formed on the back surface by holding the electronic component 1, and an operation member 4 is mounted on the protrusion 2 so as to be externally fitted from the back surface side.

The operation member 4 can be operated between the initial position and the operation position, and protrudes at an appropriate depth even in the initial position in order to prevent fingers or the like from being pinched when operating from the initial position to the operation position. The portion 2 is fitted externally, and the fitting depth is maximized at the operating position.

Rainwater or washing water that wraps around the back surface side of the handle body 3 in an unoperated state, that is, in the initial position, enters the fitting portion between the operation member 4 and the protrusion 2 and stays there. If it freezes, it interferes with the operation of the operating member 4, but in the present invention in which the drainage passage 5 penetrating the inside of the protrusion 2 is formed in the protrusion 2, rainwater or the like does not stay in the fitting portion and quickly. Since it is discharged or absorbed in the drainage passage 5, there is no risk of malfunction of the operating member 4 due to freezing or the like.

In this case, if a plurality of drainage passages 5 are arranged side by side, the pipeline area of each drainage passage 5 becomes smaller, so that suction into the drainage passage 5 due to the capillary phenomenon can be expected. It is possible to effectively prevent the accumulation of rainwater or the like in the site.

Further, if the opening area of the drainage passage 5 is formed large at the upper opening end, the surface tension at the upper opening end can be reduced, so that the suction force into the drainage passage 5 can be increased.

The electronic component 1 can be housed inside the handle body 3, and in this case, the protruding portion 2 is formed as a bulging portion in the back surface direction in order to prevent the handle body 3 from protruding to the front surface.

When the electronic component 1 is arranged on the back surface of the handle body 3, the back surface of the electronic component 1 is supported by the component bearing portion 6 formed on the handle body 3, and the electronic component 1 and the component bearing portion 6 are supported by a protruding portion. As 2, the drainage passage 5 can be configured to be externally fitted by the operating member 4, and in this case, the drainage passage 5 is formed by the drainage groove 7 and the electronic component 1 recessed at the boundary between the component support portion 6 and the electronic component 1. It can be formed by the back surface.

When the drainage passage 5 is formed at the boundary between the component support portion 6 and the electronic component 1 in this way, it is not necessary to form an underdrain-shaped through hole in the protruding portion 2, so that the structure of the mold is simplified. Will be possible.

Further, when the component bearing portion 6 constitutes a handle device for a vehicle formed in an elastically deformable cantilever shape, a load is applied to the handle body 3 when the component support portion 6 is pulled to the handle body 3 to open the door, and the component support portion 6 is curved. Even if a load in the bending direction is applied to the electronic component 1, the component bearing portion 6 elastically deforms to reduce the load, so that damage, failure, etc. due to an excessive load on the electronic component 1 can be reliably prevented. be able to.

In the present specification, the left side is "front" and the right side is "rear" in FIG. 1 (a), the upper side is "front surface" and the lower side is "back surface" in FIG. 2 (a), and FIG. 1 (a) is "up and down". It is used as a reference for the direction.

A cylinder lock 12 is fixed to the rear end of the handle base 10, and an access opening 11a for the cylinder lock 12 is opened in the cover member 11. Further, as shown in FIG. 3B, a handle recess 3a is provided in the central portion of the handle body 3 in the longitudinal direction as a handle for opening the door.

As shown in FIG. 2, the cover member 11 is a thin-walled shell-shaped member for forming an outer surface shape, and studs 11b for fixing to a door are embedded at both ends, and one stud 11b is a handle base. It is fastened together with 10 and fixed to the door.

Further, as shown in FIG. 4, on the back surface of the cover member 11, a positioning rib 11c for positioning an antenna as an electronic component 1 described later and two ridges 11d forming a support seat surface of the antenna 1 are formed. And are rushed.

The handle base 10 supports, stiffens, and reinforces the cover member 11 from the back surface along the back surface of the cover member 11, and the front end edge of the opening 10a is fixed to the opening 10a opened in the central portion. A cantilever-shaped component support portion 6 is arranged.

The component bearing portion 6 is formed in a thin plate shape and is imparted with elastic deformability, and as shown in FIGS. The antenna 1 can be accommodated so as to be sandwiched between the front surface and the back surface of the cover member 11.

Further, as shown in FIG. 4, a supporting protrusion 10b of the second lever 9 is formed at the rear end portion of the handle base 10, and a connecting hole 10c of the first lever 8 is vertically formed at the base thereof. It will be opened in the direction.

The antenna 1 is formed in a rectangular parallelepiped shape, and as shown in FIG. 5, is temporarily fixed to the back surface of the cover member 11 using an adhesive tape 13 in advance, and the back surface is described above with the cover member 11 connected to the handle base 10. The antenna 1 and the component support portion 6 form a protrusion 2 to the back surface of the handle body 3 in a state of being supported by the component support portion 6.

By holding the back surface of the antenna 1 by the component bearing portion 6 in this way, the antenna 1 can be fixed without affecting the surface of the handle body 3 in terms of design.

As shown in FIG. 2, the operation member 4 is rotatably connected around a rotation axis (C4) whose front end portion is inserted into the connecting hole 10c of the handle base 10, and is connected to the initial position shown in FIG. 2A. It rotates with and from the operation position shown in FIG. 2 (b).

As shown in FIG. 5, the intermediate portion of the operating member 4 has a U-shaped cross-sectional shape that opens in the surface direction with the inside as the fitting recess 4a, and the distance between the facing inner walls of the fitting recess 4a. Is formed to be slightly larger than the widthwise dimension of the component support portion 6.

On the other hand, as shown in FIG. 2, the first lever 8 is swingably connected to the rear end portion of the handle base 10 around a rotation axis (C8) extending in the vertical direction. The first lever 8 includes an input piece 8a extending forward from the pivot position to the handle base 10, and a bifurcated branch portion 8b extending from the pivot position toward the back surface and having a bifurcated branch portion 8b at the tip.

As shown in FIG. 2, the input piece 8a of the first lever 8 abuts on the pressing protrusion 4b that bulges in the surface direction from the rear end of the operating member 4, and rotates the operating member 4 toward the operating position. Along with this, it rotates clockwise in FIG. 2 (a).

On the other hand, the second lever 9 is rotatably connected to the end surface of the support protrusion 10b of the handle base 10 around a rotation axis (C9) extending in the front-back direction. As shown in FIG. 1B, the second lever 9 has a transmission rod portion 9a to be inserted into the branch portion 8b of the first lever 8 and a latch connecting piece 9b, and FIG. When the first lever 8 rotates clockwise in a), it rotates counterclockwise from the initial position shown in FIG. 1 (b) and moves to the operating position.

The second lever 9 is urged clockwise in FIG. 1 (b) by an unexpected torsion spring wound around the rotation axis (C9) of the second lever 9, and as a result, the second lever 9 is used. The first lever 8 is urged to the position shown in FIG. 2A by the urging force to the lever 8, and the operating member 4 is held to the initial position by the urging force transmitted to the first lever 8.

As shown in FIG. 1 (b), the latch connecting piece 9b of the second lever 9 is connected to the door latch device 14 fixed in the door by using an appropriate connecting means, and the second lever 9 is operated. When rotated to the position, the latch of the door latch device 14 is released and the door can be opened. Further, the cylinder lock 12 is connected to the door latch device 14 via a cylinder lever (not shown), and the latch release operation by the second lever 9 is permitted only when the cylinder lock 12 is in the unlocked state. Cylinder.

The release operation of the door latch device 14 is performed by rotating the operation member 4 to the operation position by holding the handle recess 3a of the handle body 3 with a hand.

As shown in FIG. 5A, the open end of the operating member 4 is shallowly fitted to the protruding portion 2 composed of the antenna 1 and the component bearing portion 6 that supports the back surface of the antenna 1. Therefore, it is possible to reliably prevent a finger from being caught in the gap between the protruding portion 2 and the operating member 4 when the handle body 3 is gripped to operate the operating member 4.

Further, as shown in FIG. 4, on the surface of the component bearing portion 6, a plurality of trapezoidal water guide grooves 7 that are wide at the top and gradually narrow at the bottom are arranged side by side in the front-rear direction. When the antenna 1 is mounted on the component support portion 6, a plurality of drainage passages 5 having the shape of the water guide groove 7 as the side wall are formed at the boundary between the antenna 1 and the component support portion 6.

As shown in FIG. 5A, these drainage passages 5 are arranged at positions substantially equal to the front-back direction positions of the front and back end faces of the operation member 4 at the initial position, and are indicated by arrows in FIG. 5A. As shown, rainwater or the like that has entered the handle body 3 from above is immediately guided to the drainage passage 5, so that the protrusion 2 is prevented from staying on the upper surface.

Further, since the upper end of each drainage passage 5 is formed to be wide, suction to the drainage passage 5 is efficiently performed, and further, since the lower end is formed to be narrow, dripping from the lower end is performed. It becomes more difficult than the introduction part, and the water retention performance in the drainage passage 5 becomes high. As a result, rainwater and the like are more likely to be guided and stay in the drainage passage 5 relative to the fitting portion between the protruding portion 2 and the operating member 4, resulting in malfunction of the operating member 4 during freezing. Can be relatively reduced.

Although the upper and lower end edges of the operating member 4 are set to be at the same position in the front and back directions in FIG. 5, the portion shown by hatching in FIG. 5A is removed, and only the lower end edge is removed from the headrace. By arranging it in a position retracted to the back surface side, it is possible to prevent rainwater or the like dripping from the drainage passage 5 from staying between the lower wall surface of the operating member 4 and the protruding portion 2.

As described above, the door opening operation is performed by releasing the latch of the door latch device 14 by operating the operating member 4, and then the handle body 3 is further moved to the door opening direction in order to open the door. When the operating force (F) (see FIG. 3B) is applied, the cover member 11 is slightly deformed in the direction of decreasing the curvature and is transmitted to the antenna 1. When a force in the back surface direction is applied to the antenna 1, the cantilever-shaped component bearing portion 6 is elastically deformed as shown by an arrow in FIG. 4 (b) to prevent stress from being generated on the antenna 1. ..

As a result, the bending force due to the load in the back surface direction to both ends in the longitudinal direction of the antenna 1 or the compressive force due to the load in the back surface direction over the entire length is not generated in the antenna 1, and the antenna 1 is destroyed and the performance is deteriorated. Can be prevented.
