【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of a rear portion of a vehicle equipped with a vehicle door opening / closing device according to the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is taken along line BB of FIG. FIG.

In FIG. 1, reference numeral 1 denotes a door body, and the door body 1 is rotatably attached to the rear portion of the vehicle body 2 via a hinge 4 at an upper edge portion of a rear opening 3 of the vehicle body 2. There is. The base end of a stay 6 is rotatably supported on the vehicle body 2 via a bracket 5 fixed to the body 2, and the tip of the stay 6 is fixed to the door body 1. The stay 6 is rotatably attached to the bracket 7, and the stay 6 is configured to expand and contract according to the opening degree of the door body 1. The stay 6 is urged toward the extension side and assists in the direction of opening the door body 1.

A guide rail mechanism 9 is fixed to the left side of the ceiling portion 8 of the vehicle body 2. The guide rail mechanism 9 includes a rail main body 10 and a carrier 15. The rail main body 10 has left and right guide rail portions 11 and 12, and these guide rail portions 11 and 12 have the rail main body 10 of the rail main body 10. Rail grooves 13 and 14 are formed along the axial direction, and openings 13a and 14a of these rail grooves 13 and 14 face each other.

The carrier 15 has left and right guide bodies 16 and 17 at an upper portion thereof and a connecting portion 18 at a lower portion thereof, and a wire connecting portion 16a is formed at a front end portion of the left guide body 16.

The carrier 15 is assembled into the rail body 10 by slidably inserting the left and right guide bodies 16 and 17 into the left and right guide rail portions 11 and 12 of the rail body 10. The main body 10 is fixed to the ceiling portion 8 with screws 19.

A rear end portion of a downwardly curved arm 20 is fixed to an upper left portion of the door body 1, and a front end portion of a rod 21 is connected to a connecting portion 18 of the carrier 15 by a pin 22. The rear end of the rod 21 is connected to the front end of the arm 20 by a pin 23, and the rod 21 and the arm 20 form an operating member 30.

A drive motor 24 is mounted inside the left side of the vehicle body 2, and a wire guide pipe 25 extends from the drive motor 24 to the guide rail mechanism 9. The wire guide pipe 25 is connected to the vehicle body. It is laid on the ceiling 8 from the left inside of 2. A geared wire 26, which is a drive wire member, is inserted into the wire guide pipe 25. The geared wire 26 is moved forward and backward by the forward and reverse rotation drive of the drive motor 24. The rear end of the geared wire 26 is connected to the wire connecting portion 16a of the guide body 16 on the left side of the carrier 15.

Next, the operation of the vehicle door opening / closing device configured as described above will be described. The forward rotation of the drive motor 24 advances the geared wire 26 to move the carrier 15 of the guide rail mechanism 9 backward with the left and right guide rails 11 and 12 of the rail body 10 as guides. The door body 1 is pushed rearward through the rod 21 and the arm 20 and the door body 1 is lifted upward through the hinge 4 to open the rear opening 3.

When closing the rear opening 3 with the door body 1, the above operation is performed in reverse. That is, the reverse rotation of the drive motor 24 causes the geared wire 26 to retract, and the carrier 15 of the guide rail mechanism 9 to move forward with the left and right guide rail portions 11 and 12 of the rail body 10 as guides. Then, the door main body 1 is pulled forward through the rod 21 and the arm 20, and the door main body 1 is lowered downward through the hinge 4 to close the rear side opening 3.

A guide rail mechanism 9 is arranged on the ceiling portion 8 of the vehicle body 2, and the drive motor 24 can be arranged in an extra space other than the ceiling portion 8, for example, inside the left side of the vehicle body 2. It is not necessary to take a large installation space in the ceiling portion 8.

[0018]

[Effect of device]

 As described above, according to the present invention, the guide rail mechanism having the rail body and the carrier that moves back and forth in the axial direction of the rail body is provided on the ceiling of the vehicle body, and the guide rail mechanism is provided on the carrier and the vehicle body so as to be openable and closable. The door body is connected to the door body via an operating member that moves by moving the carrier forward and backward to open and close the door body, and the carrier of the guide rail mechanism is reciprocated by forward and reverse rotation drive of a drive motor. Since it is connected to the drive wire member, the drive wire member is moved forward by the normal rotation drive of the drive motor, and the carrier is moved backward with the rail body as a guide, and the door body is moved through the operation member. By pushing backward to lift up the door body via the hinge to open it, and reverse the above operation to close the door body. Sea urchin, to be able to open and close the door body without using a complicated link mechanism, the configuration is simplified. In addition, a guide rail mechanism is placed on the ceiling of the vehicle body, and the drive motor can be placed in an extra space other than the ceiling, eliminating the need for a large installation space in the ceiling.
