Door member opener apparatus for vehicle
View Patent ↗A door member opener apparatus for a vehicle includes an engaging mechanism, a lock mechanism, a clearing mechanism, and an ECU (electronic control unit). The engaging mechanism includes a striker and a claw member that rotatively moves to engage with the striker. The engaging mechanism engages a tailgate with a car body. The lock mechanism regulates rotative movement of the claw member. The clearing mechanism clears the regulation of the rotative movement of the claw member when a handle member is operated. The ECU sets the amount of time before the lock mechanism can regulate the rotative movement of the claw member equal to a normal driving time.
1. A door member opener apparatus for a vehicle comprising:
an engaging mechanism comprising a striker and a claw member, the striker being fixed to one of a car body and a door member provided in the car body, the claw member being rotatively movably supported by the other of the door member and the car body, the claw member being capable of being engaged with the striker while the door member is in a regular closed state and in a half open state, the claw member being urged in a direction in which the engagement with the striker is cleared;
a lock mechanism which regulates rotative movement of the claw member in the direction of an urging force while the door member is in the regular closed state or in the half open state;
a clearing mechanism which clears the regulation, by the lock mechanism, of the rotative movement of the claw member upon a request for opening of the door member, the clearing mechanism allowing the lock mechanism to regulate the rotative movement of the claw member after a first predetermined time has elapsed, the first predetermined time being determined taking re-closing of the door member in the half open state into account;
duration detecting means for detecting the duration of the closed state of the door member; and
control means for determining that a next request for opening of the door member is not intended to re-close the door member when the duration of the closed state of the door member exceeds a second predetermined time, the control means then setting the amount of time before the lock mechanism can regulate the rotative movement of the claw member, longer than the first predetermined time.
2. A door member opener apparatus for a vehicle comprising:
an engaging mechanism comprising a striker and a claw member, the striker being fixed to one of a car body and a door member provided in the car body, the claw member being rotatively movably supported by the other of the door member and the car body, the claw member being capable of being engaged with the striker while the door member is in a regular closed state and in a half open state, the claw member being urged in a direction in which the engagement with the striker is cleared;
a lock mechanism which regulates rotative movement of the claw member in the direction of an urging force while the door member is in the regular closed state or in the half open state;
a clearing mechanism which clears the regulation, by the lock mechanism, of the rotative movement of the claw member upon a request for opening of the door member, the clearing mechanism allowing the lock mechanism to regulate the rotative movement of the claw member after a first predetermined time has elapsed, the first predetermined time being determined taking re-closing of the door member in the half open state into account;
half-open-state detecting means for detecting the half open state of the door member; and
control means for determining that a next request for opening of the door member is intended to re-close the door member if the door member is half open upon the request, the control means then setting the amount of time before the lock mechanism can regulate the rotative movement of the claw member again, equal to a first predetermined time, the control means setting the amount of time before the lock mechanism can regulate the rotative movement of the claw member again, longer than the first predetermined time if the door member is not half open upon the request.
3. The door member opener apparatus for a vehicle according to claim 1 or claim 2 , which further comprises an open-state detecting means for detecting that the door member has been opened to a position corresponding to a predetermined spacing, and in which once the door member has been opened to the position corresponding to the predetermined spacing, the lock mechanism can regulate the rotative movement of the claw member.
