Referring to Figures 1A, 1B, 1C, 5, 19, 21, the main structure of the door lock device 1 of the present invention comprises three parts: the first part is an engaging portion for holding a switch for controlling the door, and the second part is by electric The door is made from a full lock (Full Latch) to a first driver (Actuator) 2 that opens into a half-lock (Half Latch), and the third part is a second drive that causes the door to move from a half-lock to a full open (Full Open). 3.

The engaging portion mainly includes an engaging portion main body 13 and a base plate 4. Inside the meshing portion main body 13, a gusset 5 that can keep the door closed and a lock plate 6 that controls the shackle 5 are provided, and the gusset 5 and the lock plate 6 are in the same plane. The shafts 10 and 11 are fixed to the base plate 4, and the gusset plate 5 and the lock plate 6 are rotatable about the shafts 10 and 11, respectively.

The present invention also configures a Bumper Rubber 12 that is subjected to a reaction force of the Striker 25 when the door is closed, wherein the seat 25 is attached to the vehicle body side.

Under the action of the springs 8, 9, the gusset 5 and the lock plate 6 can be returned to their original positions. The spring 8 can eject the Striker Pin 25a of Fig. 2 as shown in Fig. 4. The spring 9 can cause the first claw portion 5e and the second claw portion 5d of the gusset 5 to engage.

A lock pin (Pawl Pin) 7 is fixed to one end portion of the lock plate 6 and penetrates the long hole 13b of the engaging portion main body 13. A first unlocking lever 15 and a second unlocking lever 16 that mesh with the lock plate projection 7 are disposed on the inner surface of the meshing portion main body 13. Referring to Figures 14-16, the second unlocking lever 16 urges the shaft 11 toward the center, and the first unlocking lever 15 is actuated by the bearing 14b of the engaging portion main body 13 and the bearing 14c on the bracket 19 side. The first unlocking lever 15 and the second unlocking lever 16 respectively act on the lock plate projection 7 to rotate the lock plate 6, thereby controlling the opening state of the buckle plate 5.

Referring to FIGS. 17-21, the first driver 2 and the second driver 3 decelerate the rotational power output of the motor by a worm gear (Worm Gear) and then decelerate from the gear (Gear) to the links 17, 18. Also provided is a spring 22 for directly returning the actuating links 17, 18. The gusset 5 includes a first claw portion 5e and a second claw portion 5d at two different positions, wherein the first claw portion 5e is used to control a full Latch state, and the radius dimension thereof is indicated by R1 in FIG. The second claw portion 5d is used to control the Half Latch state, the radius of which is indicated by R2 in FIG. 3, where R2 is greater than R1.

By actuating the first actuator 2, the door can be opened to the half of the 10th and 11th drawings. Lock status. Then, by the second actuator 3, the door can be further opened to the fully open state. Alternatively, the current can be simultaneously actuated through the first and second actuators 2, 3, as shown in Figures 12 and 13, to cause the door to be fully locked to fully open. When the first and second actuators 2, 3 are simultaneously actuated, a large force can be applied to the lock plate pin 7. The open operating mechanism causes the motor output power of the first and second actuators 2, 3 to be decelerated via the gear and then transmitted to the connecting rod, and the output power can be further improved by the large-sized motor and the multi-stage speed reducing mechanism.

Referring to FIGS. 6-9 and 2 to 3, the power output from the first driver 2 acts on the first unlocking lever 15 provided inside the meshing body 13 via the connecting rod 17, and then the end of the first unlocking lever 15 Acting on the lock plate pin 7 causes the lock plate 6 to actuate. The actuated lock plate 6 is stopped from the state of Fig. 2 to the state of Fig. 3, and the gusset 5 is rotated by the spring force of the spring 8 and the lock band 25a. At this stage, the first unlocking lever 15 is stopped by the stopper portion 13a provided to the engaging portion main body 13. That is, the movement of the lock plate 6 does not exceed the stroke of the second claw portion 5d of the gusset 5, and stops.

The amount of movement (opening amount) of the door after the above-described actuation is generated by the elastic force of the component damper 12 inside the meshing portion main body 13 and the waterproof rubber at the periphery of the door.

Referring to FIGS. 8 to 11 and FIGS. 3 to 4, the power output from the second actuator 3 acts on the second unlocking lever 16 disposed inside the meshing body 13 via the link 18, and then the second unlocking lever The end of the 16 acts on the lock plate projection 7 to actuate the lock plate 6.

When the gusset 5 is actuated to the position of Fig. 4, the door can be opened. If safety is considered, the door is preferably fully opened by the assistance of the occupant.

Actually, the mechanism for electrically releasing the door lock device needs to detect the action state of the component to be controlled. Specifically, the actuation of the two drivers 2 and 3 is controlled by an electronic control unit (ECU).

Based on the above, we can know:

1. Problems with the prior art

When the laterally opened door is opened by remote control, it is assumed that the vehicle may be bumped when the vehicle is in the parking state and the vehicle is fully open when the vehicle is parked on a slope or subjected to wind, or the distance between the vehicles is insufficient. The surrounding objects may cause a major accident. As far as safety considerations are concerned, in the current technology, it is necessary to open the door and human operation is necessary.

2. Effects of the invention

The way that the laterally opened door is powered off does not require the door handle to be opened, and the vehicle design feel can be improved.

The present invention emphasizes safety. The aforementioned remote control operation ensures the safety of opening the door by stopping at the position of the secondary engagement, and the door is fully opened without an operation.

Because of the electrical action, there is no need to connect the parts when the door is opened, and only a simple cover (Cover) 24 is needed, as shown in Fig. 18, for shielding the gusset 5, the lock plate 6, the first unlocking lever 15, and the When the lock lever 16 is unlocked, the anti-theft performance can be exerted.

3. The effect of the system

By adopting the present invention on a vehicle, as long as the control system of the ECU is utilized, all the switches provided in the vehicle can be opened.

This embodiment is not particularly described, but the switch for controlling each component is of course disposed in the vehicle.
