Problems solved by technology

At this time, the door opening operation of the handle main body 704 must be performed at different times, thereby reducing operability.
[0032] And, if Figure 40 As shown, in order to open the door, the opening operation of the door lock is performed, and then the door latch must be released by operating the door handle
Therefore, a two-stage operation is required, and the door opening / closing operation becomes somewhat cumbersome

Abstract

A purpose of this invention is to provide a door handle device by using a piezoelectric sensor which has a pliable structure and which provides sufficient detection sensitivity even with a light-touch, thus making it possible to control the opening and closing operation; and a keyless entry device having the same. A door handle device (100) is designed such that a door lock means which is installed on a door (13) having a handle (11) for opening and closing operation and which locks the door opening operation for this door (13) is unlocked by the operation of the handle (11). The door handle device is provided with a piezoelectric sensor (15) disposed on the handle (11) and formed of a piezoelectric element having flexibility, and a control section adapted to receive a detection signal from the piezoelectric sensor (15) produced by contact with the handle (11), and to cancel the lock imposed by the door lock means.

Description

technical field [0001] The present invention relates to a handle device capable of controlling an opening / closing operation by detecting the operation of the handle device by means of a sensor provided to the handle device such as a door handle, and a keyless entry system having the handle device. [0002] Also, the present invention relates to a door opening / closing device suitable for a keyless entry system for locking / unlocking a door of a vehicle such as an automobile without operation using a key. Background technique [0003] When the door lock is opened by operating the door handle of the vehicle, a sensor for detecting the touch or operation of the handle is provided to the door handle, thus having a function of unlocking the door lock in a predetermined state when a detection signal is output from the sensor. [0004] For example, Patent Document 1 discloses a door handle device for a vehicle that unlocks a door lock by using a contact-connection type switch such as...
