  FIG. 8 is a block diagram showing a control system of the door opening and closing apparatus described above. An authentication processing unit 101 shown in FIG. 1 performs authentication by wireless communication with, for example, a portable device 102 possessed by a user of a four-wheeled vehicle, and gives the authentication result to the opening / closing control unit 100. The door opening switch 103 is a switch operated when the door D is opened. In the present embodiment, as shown in FIG. 3, a door opening switch 103 is provided on the upper part of the rear edge on the outer surface of the door D and on the vehicle interior side of the door D. The lock switch 104 is a switch for invalidating the door opening switch 103 and is provided on the vehicle interior side of the door D. The lock display unit 105 is for displaying whether or not the lock switch 104 is operated, and is provided adjacent to the lock switch 104. The lock display unit 105 may be any device as long as it can visually display the state of the lock switch 104. For example, the lock display unit 105 can be lit and displayed by a lamp or LED. When various information is given from the authentication processing unit 101, the door opening switch 103, and the lock switch 104, the opening / closing control unit 100 is based on a program or data given in advance, and the door opening actuator unit 20 or the lock display unit. This is for general control of 105 and the like.

  Hereinafter, operation | movement of the door opening / closing apparatus mentioned above is demonstrated sequentially. First, when the door D is in an open state with respect to the vehicle main body B, the latch unit 10 is arranged in the open position as shown in FIG. 4-1. When the door D is closed from this state, the striker S provided in the vehicle main body B enters the cutout groove 11a of the latch housing 11, and the striker S eventually comes into contact with the latch engaging portion 12c of the latch 12. As a result, the latch 12 rotates counterclockwise in FIG. 4 against the elastic force of the latch spring. During this time, the ratchet 13 is such that the protruding end surface of the engaging portion 13a is in sliding contact with the outer peripheral surface of the latch 12 due to the elastic force of the ratchet spring. Rotate to.

  When the door D is further closed from the state described above, the amount of the striker S entering the notch groove 11a gradually increases, so that the latch 12 further rotates counterclockwise, as shown in FIG. Eventually, the engaging portion 13 a of the ratchet 13 reaches the engagement groove 12 a of the latch 12. In this state, the latch locking portion 12c of the latch 12 comes into contact with the engaging portion 13a of the ratchet 13, so that the clockwise rotation of the latch 12 is prevented against the elastic restoring force of the latch spring. It will be. In addition, since the hook portion 12b of the latch 12 is arranged so as to cross the notch groove 11a, the striker S moves in a direction away from the notch groove 11a by the hook portion 12b, that is, the door D opens to the vehicle body B. Door movement is prevented (half-latched state).

  When the door D is further closed from the half latch state described above, the striker S entering the notch groove 11a further rotates the latch 12 counterclockwise via the latch locking portion 12c, and the striker S is notched groove 11a. To the back (outside the vehicle). During this time, the ratchet 13 rotates clockwise in FIG. 4 against the elastic force of the ratchet spring by the hook portion 12b of the latch 12 coming into contact with the upper surface of the engaging portion 13a, and the hook portion 12b of the latch 12 passes. At that time, it immediately rotates counterclockwise by the elastic restoring force of the ratchet spring. As a result, as shown in FIG. 4C, the hook portion 12b of the latch 12 comes into contact with the engaging portion 13a of the ratchet 13, so that the latch 12 rotates clockwise against the elastic restoring force of the latch spring. Rotation will be prevented. Even in this state, since the hook portion 12b of the latch 12 is arranged so as to cross the notch groove 11a, the striker S may move in a direction away from the back (outside of the vehicle) of the notch groove 11a. As a result, the door D is kept closed with respect to the vehicle main body B (full latch state).

  In the fully latched state, as shown in FIG. 9, the driven pin 22 b of the output lever 22 in the door opening actuator unit 20 is in contact with the smallest diameter portion of the circumferential cam 28, and the open lever 23 The pressing operation piece 23c is located at a position slightly away from the pressing relay portion 14c at a position slightly outside the pressing relay portion 14c of the ratchet lever 14, and the pressing relay piece 14d of the ratchet lever 14 is It is occupied at a position separated from the pressing pin 30, and the pressing pin 30 is in a position most retracted to the outside of the vehicle by the pressing force of the return spring 33.

  When a person carrying the portable device 102 approaches the vehicle from the above-described full latch state, an authentication process is performed between the portable device 102 and the authentication processing unit 101. If it is determined that the portable device 102 is authentic as a result of the authentication process, the opening / closing control unit 100 described above activates the door opening switch 103 and monitors the door opening switch 103 (unloading). Locked).

  When the activated door opening switch 103 is turned ON, the opening / closing control unit 100 drives the drive motor 27 of the door opening actuator unit 20 to rotate the cam gear 24 as shown in FIGS. 10 and 11 sequentially. As a result, the output lever 22 and the open lever 23 are rotated clockwise. As a result, the rotation of the open lever 23 is transmitted to the ratchet lever 14 via the pressing operation piece 23c and the pressing relay piece 14d, and the ratchet lever 14 and the ratchet 13 rotate counterclockwise. When the ratchet 13 rotates counterclockwise, the contact engagement state between the hook portion 12b of the latch 12 and the engagement portion 13a of the ratchet 13 is released, and the latch 12 rotates clockwise in FIG. 4 by the elastic restoring force of the latch spring. Rotate. Therefore, as shown in FIG. 4A, the notch groove 11a is opened, and the striker S can move in a direction away from the notch groove 11a, so that the door D can be moved to open relative to the vehicle body B. become.

  At this time, as shown in FIG. 11, the press relay piece 14 d moves the press pin 30 forward with the rotation of the ratchet lever 14, and therefore, as shown in FIG. 5B, The head 32 presses the surface facing the outside of the vehicle main body B, and the door D is pushed out of the vehicle main body B and moved outward. As a result, even if the door D and the weather strip are stuck to each other at the time of freezing, the door D can be reliably opened without requiring the door opening operation with the door handle. Become.

  When it is determined that the portable device 102 is not genuine as a result of the authentication process described above, the opening / closing control unit 100 maintains the door opening switch 103 in a disabled state (locked state). Therefore, any operation of turning on the door opening switch 103 by a person who does not have the regular portable device 102 or operation of turning on the door opening switch 103 by a person who does not have the portable device 102 is ignored. become. When the user who has the authorized portable device 102 moves away from the vehicle after opening the door or without opening the door, and the portable device 102 reaches outside the wireless communication area, the opening / closing control unit 100 The door opening switch 103 is restored to the invalidated state again. Therefore, it is possible to ensure a desired anti-theft property for the vehicle.

  On the other hand, when the lock switch 104 is turned ON after entering the vehicle compartment from the opened state, the opening / closing control unit 100 maintains the door opening switch 103 in a disabled state and also opens the opening through the lock display unit 105. The state in which the door switch 103 is disabled is displayed. As a result, the occupant can be prompted to turn on the lock switch 104, and after the lock switch 104 is turned on, the door 103 is inadvertently turned on by mistake. It is possible to prevent the situation where D is in the open state.

  If the lock switch 104 is turned OFF, the opening / closing control unit 100 activates the door opening switch 103 again. Therefore, if the vehicle door opening switch 103 is turned ON, the door opening by the door handle is performed. The door D can be reliably opened without requiring an operation.

  Here, when a trouble occurs in the electric system such as a battery (not shown) mounted on the vehicle goes up, the above-described control system does not operate and the door opening actuator unit 20 is driven. Therefore, the door D cannot be opened by turning the opening switch 103 ON. In such a case, according to the door opening and closing device, the lid C is opened by the external key member 54, and then the internal key cylinder 60 is rotated by the key member 63. Since the ratchet lever 14 rotates counterclockwise from the state shown in FIG. 9 through the second wire cable W2, the contact engagement state between the hook portion 12b of the latch 12 and the engagement portion 13a of the ratchet 13 is released. The door D can be moved open. Of course, if the occupant can operate the internal operation lever 40, the operation causes the open lever 23 to rotate clockwise from the state shown in FIG. 9 through the first wire cable W1. And the engagement portion 13a of the ratchet 13 is released and the door D can be moved to open. Therefore, even when a trouble occurs in the electrical system, the door D can be opened, and there is no possibility of causing a situation in which, for example, an occupant is trapped inside the vehicle.

  Thus, according to the vehicle to which the door opening / closing device is applied, since the door opening operation by the door handle is not required when the door D is opened, the door handle is omitted and the degree of freedom in vehicle design is significantly increased. Will be able to.

  Moreover, even when a trouble occurs in the electrical system such as when the battery runs out, the door D can be reliably moved to open. In this case, in order to perform the door opening operation, the external key member 54 and the key member 63 are required, so that desired anti-theft performance can be ensured for the vehicle.
