Inside and outside of the car door, there are door latches for locking and unlocking doors, door open and close operations, inside handles and outside for door open operation. A door lock mechanism that enables a door lock and unlock operation using a handle, a key or a button, and a safety knob for manually operating the door lock state are provided.

In general, when the driver inserts the vehicle key into the key cylinder (4 in FIG. 2) of the door lock mechanism and rotates the key, the rotational force is transmitted to the door latch by the mechanical and circuit connection structure to operate the door lock and unlock. This is done.

Alternatively, the door lock and unlock can be performed by the button operation of the remote control (fob key), and in a vehicle equipped with a PIC (Personal Identification Card) system, when a driver approaches the vehicle with a smart key The door lock by the latch is released and the driver can immediately open the door.

Alternatively, while holding the smart key, press the button on the outside handle to release the door lock and pull the outside handle to open the door.

In addition, when operating the outside handle while the door lock is released by the door latch, that is, the door unlock state, the operating force of the handle is transmitted to the door latch through a cable (or rod) connected between the outside handle and the door latch. The door opening operation (operation for releasing the restraint of the striker installed in the vehicle body) of the door latch is made, thereby allowing the user to open the door.

The mechanical connection structure between the outside handle and the door latch to allow the door to be opened in the door unlocked state will be omitted since it is a known technical matter.

Meanwhile, when the electric hidden handle is applied as an outside handle, a motor for rotating the handle is provided. The motor on the handle side pulls the handle out of the door panel so that it can be operated only when the door is released, or when not used. In order to be stored inside the door panel so as not to be prevented, the handle is positioned so as not to be pulled out from the door panel when locked.

When the remote control is unlocked or a driver with a smart key approaches the vehicle, the motor is driven to protrude out of the door panel to pull the handle.

1 is a view showing the electric hidden handle of the present patent, (a) is a state in which the handle (2) is pulled in so as not to protrude out of the door panel (1), (b) the handle (2) can be pulled operation (C) shows the state after the user pulls the handle 2 and pulled out the door panel 1 outside.

As shown, the handle 2 is retracted inside the mounting portion of the door panel 1 so as not to protrude from the door panel surface, and the handle 2 is slid forward by the internal motor 3, not shown. The door panel 1 is pulled out so that the driver can operate it.

Conventional electric hidden handle and door latch structure is shown in 'Korean Patent Publication No. 10-1637820'.

FIG. 2 is a schematic view showing the conventional electric hidden handle and the door latch, in which the handle 2 is accommodated by the motor 3 and the protruded state. (B) shows a state in which the motor 3 is operated to protrude outward so that the handle 2 can be pulled and operated.

Even when such an electric hidden handle is applied, the rotational force is transmitted to the door latch 5 when the vehicle key is inserted into the key hole of the door lock mechanism and the key is rotated, so that the door lock and unlock operation can be performed.

In addition, when operating a button of a remote controller (not shown) or accessing a vehicle with a smart key, the door lock / unlock may be made by the electric actuator 6 including the motor inside the door latch 5. In this case, the door lock and unlock operation can be made independently of the withdrawal of the handle since the door latch also has its own actuator (6).

However, the handle 2 and the door latch 5 are mechanically connected through a cable 7 or electrically connected through a wiring, and the cable 7 is used for the door opening operation.

That is, when the handle is pulled out by the motor 3 on the handle 2 side, when the user pulls the handle in the door unlock state, the operating force of the handle is transmitted to the door latch 5 through the cable 7, As a result, the door latch 5 connected by the cable 7 is operated to open the door.

The reduction gear is connected to the motor 3 for drawing the handle 2 so that the reduction gear receives the power of the motor 3. In addition, the reduction gear transmits power to the system for drawing the handle.

However, the prior art has a complicated structure of the system for drawing out the handle and the reduction gear, so that the number of parts increases or a problem occurs frequently.

Referring to the handle driving process of an embodiment of the 'Korean Patent Publication No. 10-1637820'. When the motor is running, the worm gear installed in the motor is turned. Worm gears transmit power to the rotary gears engaged with the shock gears. The drive member connected to the rotary gear rotates about the hinge axis of the drive member. One end is hinged to the hinge shaft and connected to the driving member, and the other end of the driving arm hinged to the handle rotates in accordance with the rotation of the driving member to transmit power to the handle. The handle is pulled in or out according to the rotation direction of the motor. (See paragraphs [0038] and [0044] of Korean Patent Publication No. 10-1637820)

One embodiment of Korean Patent Publication No. 10-1637820 has a problem in that a failure occurs due to a weak coupling force when the hinge is worn due to a plurality of hinge couplings.

Referring to the handle driving process of another embodiment of the 'Korean Patent Publication No. 10-1637820'. When the motor is running, power is transmitted to the gear unit installed in the motor. The gear unit transmits power to the drive shaft. The first drive member is integrally coupled to the upper end of the drive shaft, and the second drive member is integrally coupled to the lower end of the drive shaft. Therefore, the first driving member and the second driving member rotate by the rotation of the drive shaft. The protrusions which contact the cam surfaces of the first driving member and the second driving member and are formed on one end of the first driving arm and one end of the second driving arm, respectively, are rotated about the driving shaft by the rotation of the first driving member and the second driving member. Move outwards along the guide holes. As the projection moves, the first driving member and the second driving member each rotate the projection about a central axis. The handles connected by hinge coupling to the other end of the first driving member and the other end of the second driving member are drawn in or drawn out by rotation of the first driving member and the second driving member. At this time, when the first driving member is in contact with the projection and the cam surface, the projection enters into the locking groove of the first driving member, and when the second driving member is in contact with the projection and the cam surface, the projection is entering into the locking groove of the second driving member.

Another embodiment of the 'Korean Patent Publication No. 10-1637820' is repeated the process of separating and reassembling the projections in the locking groove, the projections and the first driving member and the second driving member by using the elastic force of the spring member Since it keeps in contact continuously, there is a problem that a failure occurs due to the weakening and elastic force.

Referring to the handle driving process of the 'US Patent No. 8690204' as follows. When the actuator is activated, power is transmitted to a rotation axis connected to the actuator. When the rotating shaft rotates, a drive gear, which is a bevel gear installed at each end of the rotating shaft, rotates. The driven gear then engages with the drive gear and engages the swing axis, respectively. The swing shafts are respectively connected to the second ends of the swing arms, and the swing arms rotate as the swing shafts rotate. Control arms are connected to the first end of the swing arm by pin joints, respectively. In addition, a grab bar is connected to one end of the control arm by a pin joint, and pins are formed at two ends of the control arm, respectively, and are located in a slot. Therefore, when the swing arm rotates, the control arm slides left and right along the slot and the handle is pulled in or out according to the rotation direction of the rotating shaft.

The embodiment of the US Patent No. 8690204 has a problem in that due to a plurality of pin joint couplings, when the pins are worn, the coupling force becomes weak and a failure occurs.

In addition, the technique of Korean Patent Publication No. 10-1637820 is electrically operated by the lock and unlocking electric actuator 6 of the door and the door opening is mechanically operated by the cable 7. The technique of allowing the door open operation to be electrically operated so that it can be operated more easily than the mechanical means is disclosed in Korean Patent Publication No. 10-0256175.

Korean Patent Publication No. 10-0256175 includes a sensing sensor switch 80 to which an electrical contact is connected or disconnected by the operation of the latch gear 20. The detection sensor switch 80 functions to block the power supply so that the latch gear 20 does not rotate any more when the latch gear 20 is in the open state. However, the detection sensor switch 80 has a problem in that when the latch gear 20 is in the closed state, an electrical malfunction occurs to prevent the latch gear 20 from being opened while driving.

<Outer handle withdrawal process>

Hereinafter, a process of drawing the outer handle 800 will be described.

13 illustrates a state in which the outer handle 800 is drawn out.

When the outer handle 800 is drawn out through a key, a remote controller, a switch, or the like, the controller operates the driving unit 1900.

When the motor 1910 is operated, the worm 1921 rotates, and as the worm 1921 rotates, the subgear 1922 rotates, and as the subgear 1922 rotates, the first main gear 1923. Rotates, and the second main gear 1924 rotates as the first main gear 1923 rotates.

When the first and second main gears 1923 and 1924 rotate, the rack 1302 of the lift 1300 meshed with the first and second main gears 1913 and 1924 rises upward.

When the rack 1302 rises upward, the lift 1300 connected with the rack 1302 also slides upward.

When the lift 1300 is slid upward, the protrusion 730 of the sliding member 700 positioned in the long hole 1301 of the lift 1300 is slid forward from the rear along the long hole 1301.

When the protrusion 730 slides forward from the rear along the long hole 1301, the sliding member 700 and the outer handle 800, which are connected to the protrusion 730, are moved forward with respect to the housing 1110 and the panel 10. Is sliding.

The protrusion 720 of the sliding member 700 is drawn out of the panel 10 through the protrusion through hole 1111. The outer handle 800 is also drawn out of the panel 10.

When the protrusion 720 of the sliding member 700 is pulled out, the locking part 710 is caught by the panel 10 and the housing 1110.

When the outer handle 800 is drawn out, a space in which the user can put his hand is formed between the outer handle 800 and the panel 10 so that the user can grasp the outer handle 800. That is, when the outer handle 800 is drawn out, the outer handle 800 is spaced apart from the outer surface of the panel 10.

Meanwhile, when the lift 1300 slides upward, the cable 33 of the door latch connection part 30 is formed by the door latch connection part locking groove 1304 of the lift 1300 as shown in FIG. 15 (b). Will be pulled. When the cable 33 is pulled, the stopper 32 of the door latch connection part 30 slides to the right as shown in FIG. 16 (b).

When the outer handle 800 protrudes to the pulled out position, the first sensor 230 detects the stopper 32 of the door latch connection portion 30. When the first sensor 230 is pressed, the first sensor 230 applies the power of the latch motor 210.

On the other hand, when the outer handle 800 is pulled out to the withdrawal complete position, the lift 1300 is to press the third sensor (23). When the lift 1300 is detected by the third sensor 23, the detected signal is transmitted to the controller so that the controller stops the operation of the driver 1900.

<Outer Handle Entry Process>

Hereinafter, a process of introducing the outer handle 800 will be described.

14 shows a state in which the outer handle 800 is retracted.

15 to 16 illustrate the state of the door latch connection part 30 according to the withdrawal and withdrawal of the outer handle 800.

When the input of the outer handle 800 is input through a key, a remote controller, a switch, a speed value of the vehicle, and the like, the controller operates the driving unit 1900.

When the motor 1910 rotates in the opposite direction as when the outer handle 800 is pulled out, the lift 1300 slides downward.

When the lift 1300 slides downward, the protrusion 730 of the sliding member 700 located in the long hole 1301 of the lift 1300 is slid from the front to the rear along the long hole 1301.

When the protrusion 730 slides from the front to the rear along the long hole 1301, the sliding member 700 and the outer handle 800, which are connected to the protrusion 730, are rearward with respect to the housing 1110 and the panel 10. Is sliding.

The protrusion 720 of the sliding member 700 is introduced into the panel 10 through the protrusion through hole 1111. The outer handle 800 also does not protrude out of the panel 10.

Meanwhile, when the lift 1300 slides downward, the cable of the door latch connection part 30 which is pulled by the door latch connection part locking groove 1304 of the lift 1300 as shown in FIG. 33) returns to its original state as shown in Fig. 15A. When the cable 33 returns to its original state, the stopper 32 of the door latch connection part 30 slides to the left as shown in Fig. 16A.

When the outer handle 800 is pulled up to the retracted position, the stopper 32 of the door latch connection part 30 is separated from the first sensor 230. If the first sensor 230 is not pressed, the controller cuts off the power of the latch motor 210.

This may prevent the latch unit 200 from being electrically malfunctioned when the outer handle 800 is inserted.

In addition, when the outer handle 800 and the lift 1300 are moved to the inlet position, the stopper is blocked by the blocking plate 1500, and the control unit which senses the current variation of the driving unit 1900 cuts off the power to complete the operation.

On the other hand, by adding a separate position detection sensor (not shown) to the inlet portion can reduce the load during the operation of the lift 1300 and the driving unit 1900 to operate more smoothly.

As a result, the first main gear detector 6632 and / or the latch 6200 of the latch main gear 6630 may be caught by the stopper 6050. In this state, even if the latch motor 6610 is operated due to an error or the like, the latch main gear 6630 is caught by the stopper 6050 so that it cannot be rotated counterclockwise. Therefore, the first driving unit cannot slide the main opening member 6300 of the door opening and closing member, so that the door cannot be opened.

In addition, when the stopper 6050 is protruded forward, the first sensor 6707 is not pressed, so that the controller does not supply power to the latch motor 6610. As such, the latch motor 6610 may be prevented from operating, thereby preventing electrical malfunction of the latch motor 6610, and the load may be prevented from being applied to the latch motor 6610.

On the other hand, even when the latch main gear (6630) is to be caught by the stopper (6050) in case of emergency pull the lever connected to the door lever connecting portion 6800 installed in the main opening member 6300, the door is opened.

When the vehicle is stopped and the lock is released, the outer handle 6020 is pulled out of the door as shown in (a) of FIG. 59. Therefore, the door latch connection part 6040 is pulled and the stopper 6050 is slid backward as shown in FIG. 59 (b). As a result, the first main gear detector 6632 of the latch main gear 6630 is not caught by the stopper 6050. In this state, when the door open is input through the driving input unit, the first driving unit is operated. As a result, the main opening member 6300 is slid as the latch main gear 6630 is rotated to automatically open the door.

In addition, when the stopper 6050 is slid backward, the first sensor 6707 is pressed to supply power to the latch motor 6610. Accordingly, the latch motor 6610 becomes operable.
