  As shown in FIG. 1 and the following figures, the handle device is formed by connecting the handle main body 4 to the handle base 2 fixed to the door 1.

  The steering wheel device is directed upward in FIG. 1 (a) when the door 1 of the vehicle is viewed from the front, on the left and in the front, and on the right in FIG. 1 (b). It is fixed to the door 1 with the posture directed to the indoor side (back side).

  As shown in FIG. 2, the handle body 4 has a handle portion 3 which is long in the front-rear direction, and a hinge block portion 13 having a spring accommodating recess 13a in the center of the back surface. It has the to-be-locked piece 14 protruding forward from the front-end | tip of the handle part 3, and the electrode 8 of an electrostatic capacitance sensor is fixed to the handle part 3. As shown in FIG.

  In addition, a drive projection 13b is provided in the hinge block portion 13 so as to protrude, and a shaft insertion hole 13c through which the rotation shaft 15 is inserted is opened in the vertical direction.

  The handle base 2 has a rear portion 16 in which a rear connection wall 16b is bridged between hinge receiving pieces 16a disposed adjacent to upper and lower opposing side walls of the hinge block portion 13 of the handle main body 4; An axial insertion hole 16c communicating with the axial insertion hole 13c of the handle main body 4 is formed in the hinge receiving piece 16a, having a front portion 17 in which the front connection wall 17b is bridged between the rising walls 17a. It is opened.

  Further, a spring receiving piece 16d projecting forward is protruded from the rear connection wall 16b of the handle base 2, and the driving protrusion 13b of the handle main body 4 is provided between the spring receiving piece 16d and the hinge receiving piece 16a. There is formed a gap through which the The spring receiving piece 16d faces the spring accommodation recess 13a of the handle body 4 in a state in which the handle main body 4 is connected as described later, and has a width direction dimension larger than that of the spring accommodation recess 13a. Is formed.

  Further, a lever 18 is rotatably supported around an axis 18a on the back surface of the hinge receiving piece 16a. One end of the lever 18 reaches the above-mentioned gap, a play notch 18b to be described later is formed at the tip, and the other end is connected to the door latch device 11 in the door 1 A connecting portion 18c of the transmission member 19 to which the other end 19 is connected is formed.

  In order to allow the clockwise rotation in FIG. 3B of the lever 18 and to restrict the counterclockwise rotation, a lever stopper portion 16e is provided in a protruding manner on the back surface of the hinge receiving piece 16a.

  Also, a solenoid as a stopper 6 is fixed to the front connection wall 17 b of the handle base 2. The solenoid 6 is of a pull type in which the plunger 7 retracts from the projecting position to the suctioning position when energized, and is used to return to the projecting state by a return spring (not shown) when the energization is stopped. At the tip of the plunger 7 of the solenoid 6, as shown in FIG. 1, an inclined surface 7a facing the back surface is formed.

  The connection of the handle body 4 to the handle base 2 is performed by inserting the rotary shaft 15 in both shaft insertion holes 13c and 16c, and in the connected state, the handle body 4 is shown in FIG. 4 from the initial position shown in FIG. It rotates to the operation position shown in FIG. 5 via the operation standby position shown.

  As shown in FIGS. 1 and 4A, a torsion spring 20 whose one end contacts the hinge receiving piece 16a of the handle base 2 and the other end contacts the ceiling wall of the spring accommodating recess 13a of the handle body 4 as shown in FIGS. Is wound, and biases the handle main body 4 to the operation standby position side. The specifications of the torsion spring 20 are determined so that the torsion spring 20 is in a natural state where the bending is eliminated when the handle body 4 is rotated to the operation standby position.

  Further, as shown in FIG. 1, the solenoid 6 brings the handle body 4 to the initial position by pressing the locking piece 14 against the biasing force of the plunger 7 in the direction of the operation standby position by the torsion spring 20. Hold.

  Therefore, in the present embodiment, when the solenoid 6 is energized and the plunger 7 is attracted, the handle main body 4 released from the regulation by the plunger 7 is released until the deflection is canceled by the restoring force of the torsion spring 20, ie, to the operation standby position Rotate. As shown in FIG. 4C, the drive projection 13b of the handle body 4 contacts the lever 18 to move in the area of the play notch 18b of the lever 18 by the rotation of the handle body 4 to the operation standby position. And there is no resistance from the lever 18.

  After that, as shown in FIG. 5 (a), when the handle body 4 is gripped and rotated to the operation position, the lever 18 is pushed by the drive projection 13b of the handle body 4 as shown in FIG. 5 (b). , And the latch release operation of the door latch device 11 is performed via the transmission member 19.

  Further, when the handle body 4 is pushed to the initial position side from this state, as shown in FIG. 5A, the locked piece 14 of the handle body 4 abuts against the inclined surface 7a formed on the plunger 7 of the solenoid 6. The plunger 7 generates a component of force in the suction direction. As a result, the plunger 7 moves in the suction direction to allow the locked piece 14 to pass, and then returns to the projecting position by the return spring, and thereafter, moves the locked piece 14 in the reverse direction, that is, the handle The rotation of the main body 4 in the direction of the operation standby position is restricted.

  FIG. 6 shows a door opening / closing control device for a vehicle using the above-described steering wheel device. The door opening / closing operation device includes a control unit 21 including a CPU 21a and a memory 21b in addition to a handle device, an authentication unit 12 for authenticating an electronic key 22 carried by a user, and a latch and lock for unlocking the door latch device 11. And an actuator 23.

  First, when the user touches the handle portion 3 of the handle main body 4 at the initial position, a touch is detected by the electrostatic capacity sensor with the electrode 8 fixed to the handle portion 3. Output an authentication start command to 12. The control unit 21 having received the authentication start command activates the authentication unit 12 and outputs an authentication code output request signal to the electronic key 22 possessed by the user from the authentication unit 12, and then the authentication code from the electronic key 22. When the authentication for the authentication code from the electronic key 22 is established, the control unit 21 causes the solenoid 6 to perform suction operation and drives the latch lock / unlock actuator 23 to operate the lock / unlock operation unit 11 a of the door latch device 11. Is operated to unlock the door latch device 11.

  In this example, although the case where the authentication start in the authentication unit 12 is performed by contact with the capacitance sensor is shown, an active signal from the electronic key 22 possessed by the user, that is, an authentication code from the authentication unit 12 It can also be configured to output the authentication code without waiting for the output request.

  The suction of the plunger 7 of the solenoid 6 causes the handle body 4 to rotate to the operation standby position, and thereafter, when the user rotates to the operation position, the latch release operating portion 11b of the door latch device 11 operates to release the latch.

  FIG. 7 shows a second embodiment of the present invention. In the embodiment described above, the case where the solenoid 6 is used for the stopper 6 and the release operation is performed by electronic control is shown, but as shown in this example, the release operation can be configured to be performed manually. . The embodiment shown in FIG. 7 shows the stopper 6 incorporated in the cylinder lock 10 for releasing the locked state of the door latch device 11, and is used at the end of the plug 10a rotated by the unlocking key (not shown). It is fixed to the cylinder lever 24 connected.

  The constituent elements substantially the same as those of the embodiment described above in the following description of the embodiment are designated by the same reference numerals in the drawings, and the description thereof is omitted.

  In the present example, the cylinder lock 10 is shown to be directly fixed to the door 1 using, for example, a clip member (not shown) or the like, but can also be fixed to the handle base 2. Further, the stopper 6 is formed by inserting the slide block 6b into the stopper case 6a so as to be able to advance and retract, and is urged toward the projecting position by the compression spring 6c. An inclined surface 6 d is formed at the tip of the slide block 6 b in the same manner as the tip of the plunger 7 of the solenoid 6.

  Therefore, in the present embodiment, when the cylinder lock 10 is in the locked state, the movement of the locked piece 14 is restricted by the slide block 6b of the stopper 6, so that the handle body 4 is held at the initial position.

  When the cylinder lock 10 is rotated in the unlocking direction from this state, the plug 10a and the cylinder lever 24 also rotate as shown in FIG. 8, and the restraint of the stopper 6 by the slide block 6b to the locked piece 14 is released. The handle body 4 is rotated to the operation standby position by the restoring force of the torsion spring 20.

  Thereafter, when the door latch device 11 is operated by rotating the handle body 4 to the operating position, the door latch device 11 is shifted to the unlocked state by the unlocking operation to the cylinder lock 10 and the latch releasing operation of the door latch device 11 is performed. The door 1 can be opened by pulling 4. In addition, when the handle body 4 is pushed from the operation position or the operation standby position, the engaged piece 14 abuts against the inclined surface 6d of the slide block 6b, and then the slide block 6b is temporarily pushed into the retracted position. The movement of the locked piece 14 is restrained by the return of the 6 b to the projecting position again.

  FIG. 9 shows a third embodiment of the present invention. In the present embodiment, the handle main body 4 is formed by projecting the cylindrical rotary shaft 9 and the lever actuating projection 26 from one end of the handle 3 toward the back side. A cam groove 28 is formed in which a cam pin 27 described later is slidably fitted.

  In addition, a cylindrical push latch engaged portion 29 is provided at the tip of the handle portion 3 so as to protrude toward the back surface side.

  The lever actuating projection 26 is formed in a cylindrical shape having a diameter smaller than that of the rotary shaft portion 9, and an insertion hole 26a of the stopper pin 30 is formed in the vicinity of the tip on the back surface side.

  The handle base 2 fixed to the door 1 is provided with a handle holding cylinder 31 at one end portion through which the rotary shaft 9 of the handle main body 4 is inserted, and is formed by holding the cylinder lock 10 at the opposite end. A push latch device as the stopper 6 is fixed adjacent to the wall surface of the cylinder 31.

  The push latch device 6 restrains the push latch engaged portion 29 by pushing the push latch engaged portion 29 of the handle main body 4 described above to restrict the detachment from the push latch device 6, and the push latch engaged again. By pushing in the locking portion 29, the restraint is released, and the push latch locked portion 29 is allowed to be released.

  Also, a lever 18 having a coupling 18c for coupling the transmission rod 19 to the door latch device 11 at the opposite end is rotatably coupled to the handle base 2 at one end thereof and around the shaft 18a. Ru.

  The handle device is assembled by inserting the rotary shaft portion 9 of the handle main body 4 into the handle holding cylinder 31 of the handle base 2, and a cam pin so that the handle holding cylinder 31 fits in the cam groove 28 of the handle main body 4. 27 is fixed.

  Further, in order to prevent the handle main body 4 from being separated from the handle base 2, the stopper pin 30 is inserted into the insertion hole 26 of the handle main body 4 as shown in FIG. It is fixed so as to protrude in the orthogonal direction.

  Furthermore, the handle main body 4 is urged in a projecting direction by a compression spring 32 for winding the lever actuating projection 26 of the handle main body 4 between the handle main body 4 and the handle base 2. The push latch engaged portion 29 is locked to the push latch device 6 of the handle base 2, and the handle body 4 is held in the initial position against the biasing force of the compression spring 32.

  Therefore, in the present example, once the handle body 4 is pushed from the initial position, the restraint of the handle body 4 by the push latch device is released, and the handle body 4 is moved to the front side by the restoring force of the compression spring 32 as shown in FIG. Moving.

  As the cam groove 28 receives a rotational force by the cam pin 27 along with the movement to the surface side of the handle body 4, the handle groove 4 rotates around the rotation shaft 9 as shown in FIG. 11. The cylinder lock 10 covered by the handle portion 3 of the handle main body 4 is exposed to the outside by the rotation of the handle main body 4, and thereafter, the door latch device 11 is unlocked by operating the cylinder lock 10. it can.

  Further, along with the frontal movement of the handle body 4 and the rotational movement, the stopper pin 30 is also rotated to face the actuated flange portion 18d of the lever 18, and the handle body 4 is pulled out from this state in the front direction When the translational movement is performed, as shown in FIG. 11B, the lever 18 is rotated by the stopper pin 30, and the latch release operation of the door latch device 11 is performed.

  FIG. 12 shows a fourth embodiment of the present invention. In this example, the stopper 6 of FIG. 11 is changed to a solenoid 6, and a first cam groove 33 in which a cam pin 27 driven into the handle holding cylinder 31 is slidably fitted in the rotary shaft portion 9 of the handle main body 4 The second cam groove 34 in which the plunger 7 of the solenoid 6 slidably fits is formed.

  As shown in FIG. 12 (b), the second cam groove 34 has an upward traveling path 34a extending in the front direction from the front end (the upper end in FIG. 12 (b)) of the cam groove 28 in FIG. 9 (b). , A short oblique passage 34b extending obliquely downward from the end of the upward passage 34a, and a connecting passage 34d connected to the inclined passage 34c from the end of the short oblique passage 34b, the inclined passage 34c and the downward passage 34e extending therefrom being as shown in FIG. It corresponds to the lower part of the cam groove 28.

  Further, the starting end of the upward path of the second cam groove 34 is made a closed end 34f, and the downward movement of the plunger 7 is restricted.

  On the other hand, the first cam groove 33 is adapted to prevent interference with the cam pin 27 when the plunger 7 moves along the upward traveling path 34a, the short oblique path 34b, and the connecting path 34d of the second cam groove 34. The space portion 33a is formed in the portion.

  Therefore, in the present embodiment, when the handle main body 4 is in the initial position, the plunger 7 of the solenoid 6 abuts on the closed end 34f of the second cam groove 34 to restrict the movement to the surface side and the closed end 34f. The cam pin 27 is positioned at the beginning of the space 33 a of the first cam groove 33 by contacting the side wall 34 g adjacent thereto to restrict the rotation.

  From this state, when the electrostatic capacitance sensor detects a touch on the grip portion 3 and the authentication of the electronic key 22 is established in the authentication unit 12, the control unit 21 causes the solenoid 6 to perform suction operation and an actuator 23 for latching and unlocking. Is operated to operate the locking / unlocking operation unit 11 a of the door latch device 11 to unlock the door latch device 11.

  Also, when the plunger 7 of the solenoid 6 is sucked, the plunger 7 is separated from the second cam groove 34, and the movement in the projecting direction is restricted by the contact of the second cam groove 34 of the plunger 7 with the closed end 34f. The force in the projecting direction is applied to the handle main body 4 held in the initial position by the restoring force of the compression spring 32.

  On the other hand, the movement of the handle body 4 in the protruding direction is guided by the first cam groove 33 in which the cam pin 27 is fitted, and the handle body 4 is operated while rotating around the rotation shaft 9 as in FIG. After moving to the standby position, the door latch device 11 can be released and the door 1 can be opened by pulling the handle main body 4.

  On the other hand, if the suction control for the solenoid 6 becomes impossible due to a failure, battery exhaustion, etc., once the handle body 4 is pushed inward of the door 1, the plunger 7 terminates the upward path 34a of the second cam groove 34. It moves relatively in the direction (upward in FIG. 12 (d)).

  Thereafter, the handle portion 3 of the handle body 4 is a gap formed between the handle portion 3 and the handle accommodating portion 5 of the door 1, that is, the handle until the handle portion 3 abuts on the peripheral wall of the handle accommodating portion 5. When the main body 4 is rotated, the plunger 7 slightly moves leftward in FIG. 12B from the beginning of the short slant path 34b of the second cam groove 34. When the pressing force of the handle body 4 is released from this state, the handle body 4 moves in the projecting direction by the restoring force of the compression spring 32, and the plunger 7 reaches the inclined path 34c via the short oblique path 34b and the connecting path 34d. The handle body 4 is rotated as shown in FIG.

  When the handle body 4 is rotated, as shown in FIG. 11, the cylinder lock 10 is exposed to the outside, and thereafter, the door latch device 11 is unlocked by the operation to the cylinder lock 10 and the latch release by the handle body 4 is performed. The door 1 can be opened.
