This door handle has a structure in which an operation lever is rotatably provided on a door handle main body fixed to a door panel, and the electric device is turned on by turning the operation lever.

[0003] Conventionally, there is a flip-up type back door of a vehicle, in which an operation lever attached to a door handle is operated to electrically unlock the door. As shown in FIGS. 3 and 4, the back door D includes a wire harness W that connects a door handle 1 </ b> A attached to a door panel and an electric lock release device 8 a in the door panel attached to a ratchet mechanism 8.
And the limit switch 2A attached to the door handle 1A is turned on by the operation lever 3A to release the door lock. The operation lever 3A is formed substantially in a letter shape, and its bent portion is swingably supported on the upper wall of the door handle body 10 having a substantially U-shaped cross section that opens to the outside of the door D. The other end 37 projects to the rear side of the door handle body 10 and faces the limit switch 2A. The limit switch 2A is fixed to the back wall of the door handle body 10 at a position below the other end 37 of the operation lever 3A, and the end of the swingable contact piece 25 is
A is in contact with the tip of the other end 37 of A.

When a hand is inserted into the door handle body 10 and one end 36 of the operation lever 3A is pushed up in the direction of the arrow,
The other end 37 is lowered, and the contact piece 25 of the limit switch 2A
Is depressed, and the contacts (not shown) built into the limit switch 2A come into contact with each other to generate a signal. In response to the signal, the built-in motor of the unlocking device 8a is operated to release the engagement between the ratchet gear 81 of the ratchet mechanism 8 and the striker 9 provided on the lower edge of the door opening of the vehicle body to release the door lock.

Generally, to open a flip-up type back door, insert a hand into a door handle, push up an operation lever to release a door lock, and then apply further force while pushing up the operation lever. The door is rotated and opened by pulling the door handle upward. Therefore, a large operation force is applied to the operation lever of the door handle. For this reason, when the door is unlocked and the door is pulled up, an excessive pressing force is applied to the switch 2A via the operation lever 3A, and the switch 2A may be easily damaged and the switching action may be uncertain. Further, in the conventional door handle in which the operation lever 3A is a swing type, the operating force when the door is opened is directly applied to the shaft support of the operation lever 3A, so that the shaft support is likely to rattle, and the lever 3A can reliably move the limit switch 2A. The operation may not be possible, and is not suitable for a flip-up type back door requiring a large operation force.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a door handle which has a simple structure and which can reliably turn on / off a switch, and which prevents a switch from being damaged even when an excessive pushing force is applied to an operation unit.

The switch 2 is assembled such that both ends of the printed board 20 are fitted into grooves on the opposing surfaces of the pair of support legs 61 of the cover member 6 so as to extend between the two support legs 61, and the actuator 22 is mounted. Is disposed at the center position of the cylindrical portion 13 of the door handle main body 10. The switch 2 is provided with a projection protruding from an upper wall of the cover member 6 and a printed circuit board 20.
Is prevented from being bent upward.

The lower surface of the switch 2 has two support legs 61.
The actuator 22 faces a circular opening formed in the center of the partition wall 62. The opening of the partition wall 62 extends downward from the opening edge, and a cylindrical spring guide 63 extends along the spring members 4 and 5 described later.

The operating section 3 is made of synthetic resin or metal die-cast, and is a substantially U-shaped integrally formed body having a pair of legs 32 projecting upward from both right and left side edges of the bottom wall 31. The rib 33 is reinforced. At the end of each leg 32, a claw portion 34 protruding inward is formed.

The operation unit 3 has spring members 4 and 5 interposed between the bottom wall 31 and the switch 2 and between the bottom wall 31 and the partition wall 62, respectively. The parts 34 are assembled to be vertically movable up and down so as to engage with step portions formed on the outer wall surface of each support leg 61 of the cover member 6.

The first spring member 4 interposed between the bottom wall 31 of the operation unit 3 and the switch 2 is a compression coil spring, which is inserted into the spring guide 63 and the lower end thereof is connected to the operation unit 3.
Is placed in a concave receiving portion provided at the center of the upper surface of the bottom wall 31, and the upper end is provided with a convex portion of the actuator 22 therein, and is opposed to the receiving surface 221 of the actuator 22 at a slight interval in the vertical direction. It is.

The second spring member 5 interposed between the bottom wall 31 and the partition wall 62 of the operation section 3 is a compression coil spring and is disposed so as to surround the spring guide section 63, and the upper end is formed of the cylinder. The partition 13 is pressed around the opening of the partition wall 62 located at the center of the section 13, and the lower end is pressed against the center of the upper surface of the bottom wall 31 of the operation section 3. The second spring member 5 includes the operation unit 3
Is pressed downward, whereby the claw portion 34 of the operation portion 3 is locked to the step portion of the support leg 61, and in this state, the bottom surface of the operation portion 3 becomes a position where it protrudes slightly into the door handle body 10. ing.

The actuator 22 of the switch 2, the operation part 3, and the first and second spring members 4, 5 thus assembled are coaxial and concentric with the center axis of the door handle body 10. Eggplant The first spring member 4 has a smaller spring force than the second spring member 5.

A protrusion 35 is formed on the operation part 3 at the center between the inner surfaces of the two legs 32, while a stopper 7 protruding downward is provided at the end of the lower surface of the partition wall 62 correspondingly. It is formed. The stopper 7 collides with the protruding portion 35 when the operating section 3 is raised, and regulates the upper limit position of the rising of the operating section 3.

Further, the switch 2, the operation unit 3, and the first and second spring members 4 and 5 are protected by a seal member 15 for preventing water, dust and the like from entering the cylindrical portion 13. The sealing material 15 is a bag made of a thin rubber material, and integrally covers the inner periphery of the cylindrical portion 13 and the bottom surface of the operation portion 3.

When opening the back door of the vehicle, the operation unit 3 is manually operated.

In this case, even if the operation unit 3 is suddenly pushed up, no shocking force acts on the switch 2 due to the contraction of the first spring member 4. After the switch 2 is turned on, when the operation unit 3 further rises when the back door is lifted, the first spring member 4 further contracts and absorbs the load, so that a large load is not applied to the switch 2. Then, finally, the protrusion 35 of the operation unit 3 collides with the stopper 7 of the cover member 6 and the rise of the operation unit 3 is regulated, so that the load on the switch 2 does not exceed the allowable range. As described above, even if the operation unit 3 is pushed up strongly and suddenly, an excessive load is not applied to the switch 2 and the switch 2 can be prevented from being damaged. When the operating unit 3 is released, the operating unit 3 immediately returns to the lower limit original position due to the reaction force of the second spring member 5.

Since the first and second spring members 4 and 5 are provided at the center of the operation unit 3 and coaxially in the push-up direction, the operation unit 3 is moved up and down in a correct posture without inclination. Can be.
