Description

  The present invention relates to a door handle device that incorporates electrical components such as an antenna and a circuit board.

  In recent years, in order to improve the convenience of opening and closing operations of a vehicle door, a user carrying an electronic key with a built-in wireless device that transmits an ID signal can be locked / unlocked only by approaching / separating the vehicle. A smart entry system in which locking is performed has been developed and is already in practical use (see, for example, Patent Document 1).

  A vehicle door handle device employing such a smart entry system includes an antenna that transmits and receives an ID signal and the like, and a touch sensor (lock) that electromagnetically detects that a user has touched the door handle by a change in capacitance. Sensor and unlock sensor). When the user carrying the electronic key touches the part corresponding to the unlock sensor of the door handle to open the door, the unlock sensor built in the door handle detects it, and the antenna is connected to the vehicle authentication device. A request signal is transmitted to the electronic key via Then, the electronic key that has received the request signal transmits its own ID signal to the vehicle authentication device, and the vehicle authentication device that has received the ID signal stores the ID code included in the received ID signal in advance. If the ID code matches the ID code, the authentication is OK, and the door lock device actuator is driven to unlock the door.

  On the other hand, when the user touches a portion of the door handle corresponding to the lock sensor, the lock sensor detects it, and the vehicle authentication device drives the actuator of the door lock device to bring the door into a locked state where it cannot be opened.

  However, in the conventional door handle device adopting the smart entry system, the lower end position of the lock sensor and the lower end position of the unlock sensor are in the same position in the vertical direction. There is a problem that malfunction occurs such that the sensor and the unlock sensor are electrically connected by water and the unlock sensor side reacts even though the user touches the lock sensor side.

  The present invention has been made in view of the above problems, and its object is to provide a door handle device that can prevent malfunction even when water enters the door handle body. .

In order to achieve the above object, the invention according to claim 1

The lead-out portion of the second detection electrode is arranged to face the vertical center position of the electrode body of the first detection electrode, and the lower end position of the lead-out portion of the second detection electrode is set to the electrode body of the first detection electrode It is characterized by being shifted upward from the lower end position .

According to the present invention, since the lower end positions of the electrode bodies of the first detection electrode and the second detection electrode are shifted in the vertical direction, even if water enters the door handle body, the first detection electrode and the second detection electrode And the door handle device is prevented from malfunctioning.

In addition, according to the present invention, even if water enters the portion of the door handle body where the electrode body of the first detection electrode and the lead-out portion of the second detection electrode face each other, the electrode of the first detection electrode is not detected in this portion. Since the lower end positions of the main body and the lead-out portion of the second detection electrode are displaced in the vertical direction, the first detection electrode and the second detection electrode are not conducted by water, and malfunction of the door handle device is prevented. Can be removed.

Furthermore, according to the present invention, the lead-out portion of the second detection electrode is arranged at a position facing the electrode body of the first detection electrode, and the lower end position of the lead-out portion of the second detection electrode is set to the electrode of the first detection electrode. Since the second detection electrode is shifted upward from the lower end position, it is not necessary to narrow the vertical width of the electrode body of the second detection electrode, and the first detection electrode and the second detection electrode are located at a portion where the first detection electrode and the second detection electrode face each other. Each lower end position of the second detection electrode can be shifted in the vertical direction, and malfunction of the door handle device can be prevented without lowering the detection sensitivity.
