Description

[Detailed Description of the Invention] The present invention relates to an outer handle device with a switch, in which the outer handle device of an automobile door is equipped with a switch that turns on and off in conjunction with the operation of an opening handle.

Conventionally, a device has been proposed in which a lamp for illuminating the keyhole of a key cylinder is turned on by pulling an opening handle, thereby making it possible to easily insert a key during nighttime use.

However, the practical application of the above proposal is still in its infancy; for example, even if the switch is linked to the opening handle, a commercially available micro switch 1 can be used as is, as shown in FIG. Bracket 4 provided to match the pair of tightening bolts 3, 3 to (not shown)
A switch assembly 7 is formed in which the micro switch 1 is attached in advance and an actuator 6 that is linked to the link part 5 of the opening handle is attached, and when the outer handle device 2 is attached, an additional A co-fastening structure was adopted.

In such a structure, the number of parts is large, the structure is complicated, the device becomes large, and when assembling, the outer handle device 2 and the switch assembly 7 must be assembled from the inside and outside of the door at the same time. In particular, there was a problem that the workability of assembling the switch assembly 7 from the inside of the door was poor.

In addition, since it is very difficult to make the switch assembly 7 as a whole waterproof, the micro switch itself must be protected against water intrusion from the wind seal part or the outer handle mounting opening during car washing or rain. However, there was a problem that required the use of a special material with a waterproof structure.

The present invention was developed in view of these problems, and it simplifies the switch structure by reducing the number of parts, and greatly improves the ease of attaching the switch assembly to the outer handle device and assembling it to the door panel. While improving this, we also ensured waterproofing by making it possible to attach a waterproof cap that covers the entire switch structure, and also improved serviceability by sharing parts with the outer handle device that does not have a switch. The object of the present invention is to provide an outer handle device with a switch that can be used.

Therefore, in the outer handle device with a switch according to the present invention, a switch equipped with an actuator is attached to one of a pair of legs provided at one end of a base fixed to the outside of the door panel, and a switch equipped with an actuator is installed between the legs of the base. A cam part for operating the actuator by the swinging operation of the opening handle is provided near the pivot part of the link part of the opening handle pivotally connected by the pivot shaft, or on the pivot shaft, and the cam part and the switch etc. The handle sheet is sandwiched between the base and the door panel, and is covered with a waterproof cap that is integrally formed with the handle sheet.

Hereinafter, the present invention will be specifically explained based on the illustrated embodiments.

[First Embodiment] In Fig. 2, 11 and 12 are a pair of legs formed integrally with the base 20 (see Fig. 4) fixed to the door panel, and 13 is a swingable leg between the pair of legs 11 and 12. The link part 14 of the opening handle to be freely pivoted connects the link part 13 to the pair of legs 11,
This is a synthetic resin pivot shaft that is swingably supported between 12 parts. The pivot shaft 14 contracts in diameter when inserted from one direction into the shaft holes 11a, 12a, 13a provided in the pair of legs 11, 12 and the link part 13 at its tip, and expands again after insertion. It has an elastically deformable portion 14a that cannot be pulled out in the opposite direction thereafter, and an eccentric cam 15 that is eccentric with respect to the center of the pivot shaft 14 is provided at the rear end. Furthermore, leg 1
When the link part 13 is pivotally attached between 1 and 12 by the pivot shaft 14, a recess is formed in the radial direction of the shaft hole 13a of the link part 13 in the part of the pivot shaft 14 that fits with the link part 13. A convex portion 14b is provided along the axial direction on the outer surface of the shaft portion so as to fit into the groove 13b, and when the opening handle is swung by the engagement of the concave groove 13b and the convex portion 14b, A cam 1 provided at the rear end of the pivot shaft 14 in conjunction with the rotation of the link portion 13

and shaft holes 11a, 12a, 13 of link part 13
A concave groove 12 that allows the convex portion 14b of the pivot shaft 14 to be inserted into the shaft hole 12a of the leg portion 12 so as to pass through the shaft hole 12a of the leg portion 12.
b is recessed in the radial direction of the shaft hole 12a.

Further, 16 is attached to one leg part of the pair of leg parts 11 and 12, for example, a step part 17 protruding from the rear surface 12c in the axial direction of 12, with a bolt or the like (not shown), for example, for keyhole illumination. The micro switch 18 is an actuator of the micro switch 16 made of a plate spring material and provided diagonally upward with respect to the upper side of the micro switch 16. As shown in FIG. When the cam 15 is rotated from the off position shown in the figure as indicated by arrow a in the figure by operating the opening handle, the actuator 18 is pushed down by the rotation of the cam 15. , turn on the micro switch 16.

On the other hand, numeral 19 is a handle sheet held between the base 20 and a door panel (not shown), and a waterproof cap 19a is integrally formed on the handle sheet 19. This waterproof cap 19a has a cross section of approximately an inverted U shape, and is connected to the handle seat 19, which is an inverted U-shaped frame attached to the outer frame of the base 20, at an appropriate position by a bendable thin connecting portion 19b. The switch mechanism is assembled to the legs of the base 20, and as shown in FIG.
3. Cover the pivot shaft 14 from above with a waterproof cap 19a, and at the same time attach the handle seat 19 to the base 20. The waterproof cap 1
The center part of one side wall of 9a is formed as a downward groove part 21 to provide a base for swinging the link part (not shown), and corresponds to the leg part 12 of the part of the side wall excluding the groove part 21. A mounting hole 22 is provided below the side where the cord 25 is held, and is engaged with a locking protrusion 23 of the leg portion 12, while a cord tightening band 24 is provided to tighten and hold the cord 25.

In this embodiment, when assembling the pivot shaft, which is the only assembly member between the base and the opening handle, this pivot shaft can be used to simultaneously assemble the switch mechanism, which improves the ease of assembly. This eliminates the need for a bracket as in the conventional case, and it is possible to reduce the number of parts. Furthermore, since the switch mechanism can be covered with a waterproof cap, there is no need for the switch mechanism itself to have a waterproof structure, and the overall cost can be lower than that of the conventional one.

Furthermore, since the waterproof cap is integrated with the handle seat, the number of parts is reduced, and since the waterproof cap is connected to the handle seat,
Once the base is attached to the door panel, the waterproof cap will not come off.

[Second Embodiment] As shown in FIG. 5, in this embodiment, instead of providing the cam 15 on the pivot shaft 14 in the first embodiment, the cam 15 is provided in the axial direction of the pivot portion of the link portion 28 of the opening handle. An eccentric cam portion 28a is integrally formed on the
The actuator 1 of the micro switch 16 is supported inside one leg 30 by the cam portion 28a.
Press down on 8 to turn on the switch. In this case, the micro switch 16 has a clip 3 having a U-shaped horizontal cross section on a stepped portion 31 protruding from the lower part of the inner surface 30a facing the link portion 28 of the leg portion 30.
Attach according to 2.

As shown in FIG. 6, the clip 32 is

The microswitch 16 is immovably held on the stepped portion 31 of the leg portion 30 by c and 32c.

On the other hand, the waterproof cap 35a according to this embodiment
The handle seat 35 is the same as in the first embodiment.
A bendable thin connecting portion 35b is placed at an appropriate position.
The switch mechanism has a roughly inverted U-shape in cross section and is connected between the legs 29 and 30 of the base 27, similar to the first embodiment.
As shown in FIG. 8, the pair of legs 29, 30, link 28, and pivot shaft 34 are covered from above with a waterproof cap 35a, and at the same time, a handle seat 35 is attached to the base 27. The central portion of one side wall of the waterproof cap 35a is formed as a sloped portion 36 that is inclined downward in order to provide a base for swinging the link portion (not shown), and the sloped portion 36 of the side wall Attachment holes 37, 37 are provided below the other parts except for the locking protrusions 38, 3 of the legs 29, 30 as in the previous embodiment.

This embodiment can also achieve substantially the same effects as the first embodiment.

As explained above, according to the present invention, the switch mechanism is attached to the part where the link part of the opening handle and the pair of legs of the base are pivotally connected.
Since the conventional bracket is not required, the switch mechanism can be simplified, and since the switch mechanism can be assembled to the door panel while being attached to the outer handle device, ease of assembly can be greatly improved. In addition, since the entire switch mechanism is completely covered with a waterproof cap, it can be reliably waterproofed, and there is no need to use a special switch with a waterproof structure as in the past. It has a powerful effect. Furthermore, since the waterproof cap is formed integrally with the handle seat, the number of parts is reduced, and since the waterproof cap is connected to the handle seat, the waterproof cap will not come off after the base is attached to the door panel. Furthermore, since there are no extra parts other than the switch body, parts can be shared with outer handle devices that do not have a switch.
This has the advantage that servicing by installing options can be easily performed.
