DOOR HANDLE DEVICE
First Claim
Patent Images
1. A door handle device arranged in a door of a vehicle and capable of operating a door opening/closing mechanism of the vehicle, the door handle device comprising:
- a first handle case, which has a grip arranged to define a gap with an outer surface of an outer panel of a vehicle door;
a second handle case, which is attached to the first handle case to cover the first handle case;
a lock detection electrode arranged between the first handle case and the second handle case and capacitance-coupled to the outer panel so as to allow for detection of a door lock command based on a change in a capacitance formed with the outer panel, with the lock detection electrode including an electrode end facing toward the outer panel;
a circuit substrate arranged in the first handle case; and
a waterproof elastic body covering the electrode end;
wherein the elastic body includes a first portion, which is arranged between the circuit substrate and an inner surface of the second handle case, a second portion, which extends from the first portion along the contour of the lock detection electrode, and an opening between the first portion and the second portion, with the lock detection electrode being arranged in the opening.

Abstract
A door handle device capable of operating a door opening/closing mechanism of a vehicle is disclosed. The door handle device includes a support member, door handle, lock detection electrode, and capacitance sensor. The door handle includes a first end, second end, pivot portion, and operation portion. The capacitance sensor detects issuance of a door lock command from a change in capacitance between an outer panel and the lock detection electrode. The door handle includes a first handle case and second handle case, which covers the first handle case. The lock detection electrode is arranged proximal to and facing toward an inner surface of an upper wall or lower wall of the second handle case. The lock detection electrode is encompassed by a waterproof elastic body.

21. A door handle device for use with a vehicle including a door opening/closing mechanism and a door having an outer panel with an outer surface, the door handle device comprising:
-
a first handle case, which has a grip mountable to the door to define a gap with the outer surface of the outer panel of the door; a second handle case, which is attached to the first handle case to cover the first handle case; a lock detection electrode arranged between the first handle case and the second handle case and capacitance-couplable to the outer panel so as to allow for detection of a door lock command based on a change in a capacitance formed with the outer panel, with the lock detection electrode including an electrode end facing toward the outer panel; a circuit substrate arranged in the first handle case; and a waterproof elastic body covering the electrode end; wherein the elastic body includes a first portion, which is arranged between the circuit substrate and an inner surface of the second handle case, a second portion, which extends from the first portion along the contour of the lock detection electrode, and an opening between the first portion and the second portion, with the lock detection electrode being arranged in the opening. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
