Description

[Detailed Description of the Invention] This invention relates to a remote control device that can lock and unlock a plurality of automobile door locks at once.

When locking or unlocking a car door from the inside, the lock knob must normally be operated manually, so when the driver operates the lock knob of a door adjacent to another seat from the driver's seat, especially a rear door. The backrest of the front seat made it difficult to operate.

Recently, a device was developed that locks and unlocks each door individually using an electromagnetic locking device.
Each door must be equipped with an electromagnetic locking/unlocking device, and a special electric circuit must be installed to lock/unlock the room, resulting in a high manufacturing cost.

In order to reduce manufacturing costs, a wire-type locking/unlocking device was also developed, but this device had the drawback that it was not possible to lock or unlock the door simply by operating the manual lock knob.

Therefore, in order to enable locking/unlocking by operating the manual lock knob, we developed a wire connected to the knob lock lever of a car door lock that is operated by a manual knob, so that the wire can be connected to the operating member driven by a motor at a constant rate. To provide a remote control device for an automobile door lock that can be attached to a conventional door lock device as is and lock/unlock at one point by using a remote control device connected with the play.
