Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rear door lock device, and more particularly to a rear door lock device for a van type four-wheel drive vehicle.

[0002]

[Prior art]

 1 and 2 show a van-type four-wheel drive vehicle 1, in which side doors 3 and 3 are provided on both left and right sides of a body 2, and the side doors 3 and 3 are opened and closed to allow passengers and passengers to get in and out of the vehicle. It is carried out. A rear door 4 is provided on the rear surface of the body 2, and the rear door 4 is opened and closed so that luggage can be loaded on the rear portion of the body 2.

Each of the side doors 3 and 3 and the rear door 4 is provided with a key cylinder 5, and a key is inserted into the key cylinder 5 and rotated to operate a door lock mechanism via a lock rod. Then, the side doors 3 and 3 and the rear door 4 are locked or unlocked. The key is common with the ignition key.

[0004]

[Problems to be solved by the device]

 In the conventional van type four-wheel drive vehicle, as described above, each door is locked or unlocked by the key. In particular, with regard to the rear door, the driver or the like has to move out of the vehicle to the front of the rear door, and the operation may be forgotten, so the lock operation may be forgotten.

Therefore, when locking or unlocking the rear door, there arises a technical problem to be solved so that the rear door can be easily operated from the inside of the vehicle, and the present invention solves this problem. The purpose is to

[0006]

[Means for Solving the Problems]

 The present invention has been proposed to achieve the above object.One end of a lock rod is connected to a key cylinder of a rear door, and the other end of the lock rod is connected to a door lock mechanism to lock or unlock with a key. In a rear door formed to be locked, an electric actuator is mounted inside the rear door, one end of an actuator rod is connected to a plunger of the electric actuator, and the other end of the actuator rod and the lock rod are connected. The present invention provides a rear door locking device in which one end of the vehicle is connected by a connecting member so that the electric actuator can be operated from inside the vehicle.

[0007]

[Action]

 To lock the rear door, operate the electric actuator remotely from within the vehicle. In that case, the plunger protrudes from the main body of the electric actuator and presses the actuator rod. A portion of the lock rod near one end of the lock rod is connected to the actuator rod by a connecting member, and the lock rod is integrally moved by pressing the actuator rod. Thus, the door lock mechanism connected to the other end of the lock rod operates and the rear door is locked.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. The external appearance of the van type four-wheel drive vehicle 1 shown in FIGS. 1 and 2 has already been described in the related art, and a duplicate description thereof will be omitted. FIG. 3 shows a side edge portion of the opened rear door 4, and a latch 6 is provided on a side surface portion of the rear door 4. A service hole cover 7 for inspection and adjustment is fixed to the inside of the rear door 4 with screws, and the rear door lock device 8 is installed in the door frame with the service hole cover 7 once removed.

FIG. 4 shows the configuration of the rear door lock device 8, in which the rear surface of the key cylinder 5 projects into the door frame of the rear door 4. An arm 9 is pivotally attached to the key cylinder 5, and one end of a lock rod 10 is connected to the arm 9. The other end of the lock rod 10 is connected to a door lock mechanism (not shown), and a key is inserted into the key cylinder 5 from the front side of the rear door 4 and rotated to lock the lock via the arm 9. The rod 10 moves up and down to lock or unlock the door lock mechanism. In the illustrated state, the arm 9 and the lock rod 10 are moving upward, and the rear door 4 is locked.

Then, the electric actuator 11 is fixed inside the door frame of the rear door 4 and at a lower position of the key cylinder 5. A plunger 12 projects from the upper portion of the main body of the electric actuator 11, and one end of an actuator rod 13 is connected to the plunger 12. The other end of the actuator rod 13 is close to the lock rod 10 in parallel, and the lock rod 10 and the other end of the actuator rod 13 are connected by a connecting member 14. Further, the cable 15 of the electric actuator 11 is pulled into the inside of the vehicle from the hinge portion of the rear door 4 and is routed to the switch 16 provided near the driver's seat.

When the rear door 4 is unlocked, the driver or the like turns on the switch 16 in the vehicle, and the electric actuator 11 is actuated to operate the plunger 12 as shown by a chain double-dashed line. Contracts toward the body. Therefore, the actuator rod 13 is pulled downward, and the lock rod 10 connected by the connecting member 14 also moves downward. Thus, the door lock mechanism connected to the other end of the lock rod 10 operates and the rear door 4 is unlocked.

On the other hand, when the rear door 4 is locked, the switch 16 is turned off contrary to the above operation. In that case, the plunger 12 of the electric actuator 11 returns to the original position shown by the solid line, and the actuator rod 13 is pressed upward. Therefore, the lock rod 10 connected by the connecting member 14 also moves up integrally, and the rear door 4 is locked.

As described above, only by operating the switch 16 provided near the driver's seat, the rear door 4 is locked or unlocked, and the key operation from the outside of the vehicle becomes unnecessary. The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.

[0014]

[Effect of device]

 As described in detail in the above embodiment, the present invention can lock or unlock the rear door by remotely controlling the electric actuator mounted inside the rear door. Therefore, the conventional key operation outside the vehicle is not required, and the driver or the like can lock the rear door inside the vehicle, and the operability is significantly improved. Moreover, it is a practical idea with various practical values, such as never forgetting the lock operation, eliminating the risk of theft of luggage or accidental opening of the door, and contributing to the improvement of safety.
