As shown in FIG. 1, the opening restriction mechanism 10 is provided between a body 100 and a door 200 for getting on and off that is pivotally attached to the body 100 by a hinge 300 and between two hinges 300. Thus, the opening / closing range of the door 200 is limited between a door opening limit position and a door closing position, which will be described later.
As shown in FIG. 2 and FIG. 3, the opening restriction mechanism 10 includes a door side mechanism portion 20 provided on the door side and a vehicle body side mechanism portion 30 provided on the vehicle body 100 side.

  As shown in FIG. 3A, the door-side mechanism unit 20 is connected to the frame 21 fixed to the door 200, the driving unit 22 fixed to the upper part of the frame 21, the driving unit 22, and the frame 21. Both ends of the rotating shaft 25 are rotatably supported. The engaging column is fixed to the rotating shaft 25 and extends in a direction substantially perpendicular to the axis of the rotating shaft 25 and is arranged in parallel along the axial direction. It is comprised from the two engaging members 26 etc. which curved and formed so that it might substantially correspond to the curvature of the outer periphery of 31. FIG.

As shown in FIG. 4, the drive unit 22 includes an electric motor 22A, a worm gear 22C connected to the output shaft 22B of the electric motor 22A, a worm wheel 22D screwed to the worm gear 22C and concentrically fixed to the rotary shaft 25, and the like. Consists of
The rotation amount of the electric motor 22A is controlled in accordance with a control command from the door ECU 40. The electric motor 22A is driven by a current supplied by a drive circuit (not shown).
The worm gear 22 </ b> C and the worm wheel 22 </ b> D reduce the rotation of the electric motor 22 </ b> A with a predetermined reduction ratio and transmit it to the rotary shaft 25.

As shown in FIG. 3 (B), the vehicle body side mechanism section 30 has an engagement column 31 having a circular cross-sectional shape with which the two engagement members 26 can be engaged (contacted). The frame 32 is configured to support both ends and be fixed to the vehicle body 100 side.
When the door 200 is opened and the engagement column 31 engages (contacts) with two predetermined engagement members 26 at a predetermined door opening restriction position, the opening of the door 200 is controlled to the door opening restriction position. Limit with.

  The door ECU 40 includes hardware such as a processor and a memory, and necessary software. A signal 60 s indicating the state of the door lock 60 provided on the vehicle door 200, a signal 50 s from the control switch 50, and the like are input. Then, control processing corresponding to these, for example, drive control of the electric motor 22A described above is executed.

  The control switch 50 is a switch for setting the opening degree of the opening restriction mechanism 10. By operating the control switch 50, the door opening restriction position is set within the range of the maximum opening degree of the door 200. . For example, the control switch 50 may be provided in the vicinity of a door in the vehicle, in the vicinity of an instrument panel, or may be formed by a touch panel of an in-vehicle display device, and various configurations can be appropriately selected.

Here, an example of the operation of the opening restriction mechanism 10 and an example of the processing of the door ECU 40 when the door opening restriction position is set by operating the control switch 50 will be described with reference to FIGS. 5 and 6.
FIG. 5 is a view showing the operation of the engaging member in various states, and FIG. 6 is a flowchart showing an example of processing of the door ECU 40, and this processing routine is periodically executed.

As shown in FIG. 6, the door ECU 40 first determines whether the door lock 60 has been released (step ST1), and if it has been released, determines whether the control switch 50 has been operated (step ST2). .
When the control switch 50 is not operated, the engaging member 26 is positioned at the initial position as shown in FIG. 5A. In this case, when the door 200 is opened, the door 200 is opened. Can be opened up to its maximum opening. That is, even when the door 200 is opened to its maximum opening, the engaging member 26 does not engage with the engaging column 31.

  On the other hand, after the vehicle occupant (user) parks and stops, for example, before the door lock 60 is released and the door 200 is opened, the environment outside the vehicle (for example, another vehicle having an obstacle near the door). The degree of opening limit to be set is determined in accordance with whether the vehicle is parked in close proximity, strong winds are blowing, and the like, and the control switch 50 is operated according to the size.

  When the control switch 50 is operated, the door ECU 40 recognizes this, and outputs a control command to the drive unit 22 so that the engagement member 26 is positioned at the set opening restriction position. As a result, as shown in FIG. 5B, the electric motor 22A of the drive unit 22 is driven, and the engagement member 26 is positioned at the set opening restriction position (step ST3).

  When the user opens the door 200 after the control switch 50 is operated, when the opening degree of the door 200 reaches the set opening restriction position, the engagement member 26 is engaged as shown in FIG. Engagement (contact) with the column 31 restricts the opening of the door 200 from the opening limit position. When the engaging member 26 engages with the engaging column 31, a relatively large force (moment) acts on the rotating shaft 25 to which the engaging member 26 is fixed. Since a reduction gear including the worm wheel 22D and the worm gear 22C is interposed between the output shaft 22B of 22A, it is possible to support a large moment received by the engagement member 26.

  When the engagement member 26 is positioned at the set opening restriction position, the opening and closing of the door 200 is not restricted between the closed position of the door 200 and the set opening restriction position. is there. Therefore, the user can prevent the door 200 from being opened unexpectedly by appropriately operating the control switch 50 in consideration of the state outside the vehicle (inclination of the parking place, wind strength, etc.). The door 200 can be easily opened and closed regardless of the external state.

  When the door ECU 40 detects that a predetermined condition is satisfied, for example, that the door lock 60 shown in FIG. 2 is in the locked state (step ST4), the opening degree of the engagement member 26 is set. Automatic return from the limit position to the initial position (step ST5). This is because the engagement member 26 is preferably in the initial position shown in FIG. 5A in a state where the opening degree of the door 200 is unnecessary.

  In the above embodiment, the case where the electric motor 22A and the engaging member 25 driven thereby is provided on the door side has been described. However, the present invention is not limited to this, and the electric motor 22A and the electric motor 22A are driven by the electric motor 22A. It is also possible to provide the engaging member 26 (rotating shaft 25) on the vehicle body side and the engaging column 31 and the like on the door side.

In the above embodiment, the case where the electric motor 22A is used as the actuator for driving the engaging member 26 (rotating shaft 25) has been described. However, the present invention is not limited to this, and other actuators may be used. .
Moreover, although the said embodiment demonstrated the case where the reduction gear which consists of worm wheel 22D and worm gear 22C was interposed between the rotating shaft 25 and electric motor 22A, it is not necessarily limited to this, It is also possible to use a type of speed reducer.

  In the above embodiment, the case where the opening degree limiting mechanism 10 is disposed between the two hinges 300 has been described. However, the present invention is not limited to this, and the installation position can be changed as appropriate.

  In the above-described embodiment, the case where the present invention is applied to the door 200 for getting on and off the vehicle has been described.

  In the above-described embodiment, the control switch 50 is a switch that arbitrarily sets the opening degree of the opening restriction mechanism 10. However, for example, when the control switch 50 is pressed, the control switch 50 is configured to have a predetermined opening degree. Alternatively, the opening degree may be set stepwise according to the number of times the control switch 50 is pressed, and the configuration of the control switch 50 can be variously changed.
