Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a rear door opening/closing device for an automobile.

(Prior art) As a rear door opening/closing device for an automobile, an operating lever supported on the vehicle floor near the driver's seat is connected to a rotating shaft extending in the vehicle width direction located below the seat, and this rotating shaft is connected to the front door opening. It is connected to a rotating arm whose lower end is pivoted to the lower edge, and the upper end of the rotating arm is connected to a connecting bar extending in the front-rear direction, and a bar supported by a guide fixed to the center pillar between the front door and the rear door. There is one connected to the rear door side (Publication of Utility Model Publication No. 44-23682,
(Refer to Utility Model Publication No. 50-38897). For this device,
The rearward rotation of the operating lever rotates the rotation shaft, which causes the upper end of the rotation arm to rotate rearward and open the rear door.

(Problems to be solved by the invention) In the above-mentioned conventional system, a large space is required under the seat for arranging the rotating shaft, and its installation is troublesome. Since the rotating arm supported on the edge protrudes into this opening, it tends to get in the way of the occupant getting on and off the vehicle, making it necessary to shorten the length of the rotating arm. If the length of this rotating arm is shortened, the stroke of the connecting bar when opening and closing the rear door becomes shorter, which makes it difficult to transmit operating force to the rear door.

(Means for solving the problems) The present invention, as a means for solving the above problems,
The upper end of the rotating arm is pivotally supported on a bracket fixed to the inside of the center pillar so that the rotating arm can rotate in the longitudinal direction of the vehicle body in a substantially vertical plane. A guide member is provided inside the vehicle interior and extends within the rotation range of the rotary arm, and the lower end of the rotary arm is guided and regulated by the wall surface of the guide member. Attach a rod whose center of rotation is approximately perpendicular to the longitudinal direction of the arm, and attach the tip of this rod on the rear door side to one end of the opening/closing arm, and the other end of this opening/closing arm to the bracket attached to the rear door. To provide a rear door opening/closing device for an automobile, in which an operating lever and the above-mentioned rotating arm are connected to each other so as to be rotatable, and are rotatably attached to the vehicle body around the driver's seat via a mounting bracket, by a wire cable. It is.

(Function) In the rear door opening/closing device described above, the wire cable advances and retreats when the operating lever is rotated, and the rotating arm is guided by the guide member and rotates back and forth. The operating force for opening and closing is transmitted to the door. Since the operating lever and the rotating arm are connected by a wire cable, there is no need to take up a large space below the seat, and the rotating arm is supported by the center pillar via a bracket. By utilizing the width of the center pillar, it is possible to prevent the center pillar from protruding largely into the front door opening and the rear door opening.

Furthermore, when the rear door is opened, the reaction force acts as a force that pushes the rotating arm toward the inside of the passenger compartment via the opening/closing arm and the rod, but if the rod is located approximately at the center of the rotating arm, , the lower end of this rotating arm is guided by the guide member, so that this reaction force is received by the guide member at a position farther from the input point of the reaction force as seen from the pivoting position of the rotating arm. The contact pressure of the rotating arm against the guide member is reduced, and smooth rotation can be achieved by the guidance of the guide member.

(Effects of the invention) Therefore, according to the invention, there is no need to secure a large space below the seat by using a wire cable, and the lower end of the rotating arm is attached to the bracket that pivotally supports the upper end of the rotating arm. Since a guide member is provided to guide the rotating arm, the rotating arm and its guide member can be assembled inside the center pillar, improving ease of assembly to the vehicle body, and the guide member allows the rotating arm to move smoothly. While ensuring operability or operational safety when opening/closing the rear door by rotating the arm, the rotating arm does not protrude too far into the opening of the front or rear door to improve ease of getting in and out of the vehicle. can be achieved.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIG. 1, the operating means 1 is attached to the vehicle body on the side of the driver's seat of the seat 2, and the rear door rotating means 3 is attached to the center pillar 5 on the passenger's seat side. The moving means 3 is linked via a wire cable 6.

The operating means 1 includes a mounting bracket 8 extending in the longitudinal direction of the vehicle body and having a central portion 8b formed slightly lower than both end mounting portions 8a, 8a.
is fixed to the seat slider 7, and as shown in FIG. 2, the operating lever 4 is rotatably supported on a pivot pin 10 held at the center portion 8b by a stopper 11 via a bush 12. ing.

On the other hand, the rear door rotating means 3 includes a rotating arm 14 attached to the inside of the center pillar 5 via a bracket 13 having a U-shaped cross section. As shown in FIG. 3, the U-shaped bracket 13 includes an arm support plate 13a on the outside of the vehicle interior and a guide member 13b lower in height than the arm support plate, which are connected to each other by a bottom plate 13c. This guide member 13b is connected to the rotating arm 14.
The rotating arm 14 is located inside the vehicle body, and the rotation range of the rotating arm 14 extends in the longitudinal direction of the vehicle body. The rotating arm 14 has a lower end bent into an L-shape, and an upper end connected to the inner wall of the upper end of the arm support plate 13a on the outside of the vehicle interior of the U-shaped bracket 13 via a washer 25 to a support shaft 16. The bent lower end 1 is pivotably supported in the longitudinal direction of the vehicle body in a substantially vertical plane.
4a, a roller 15 that rolls on the inner wall surface of the guide member 13b on the inside of the vehicle interior is pivotally supported by a pin 26, and the rotation direction of the rotary arm 14 is regulated by the rolling of the roller 15 on the guide member 13b. ing.

Furthermore, a cylindrical body 1 is provided approximately at the center of the rotating arm 14.
7 is fixed substantially perpendicular to the longitudinal direction of the arm, and as shown in FIG. 4, a rod 18 is rotatably fitted into the cylindrical body 17, and the tip 18a of the rod 18 on the rear door side has a substantially arcuate shape. One end of the opening/closing arm 19 is pivoted horizontally by a pin 27, and one end of an L-shaped bracket 21 is attached to the other end of the opening/closing arm 19 via a connector 20 so as to be rotatable horizontally and vertically. The other end of the L-shaped bracket 21 is fixed to the rear door 22.

The wire cable 6 has one end inserted through a supporting piece 23 extending upward from the central portion 8b of the mounting bracket 8 and bent laterally, and connected to a fixing piece 28 projecting laterally from the operating lever 4. , the other end is U
A supporting piece 29 formed by bending the rear end of the bottom plate 13c of the character-shaped bracket 13 upward is inserted through the support piece 29 and connected to the lower end of the rotating arm 14 via a U-shaped fixture 24.

Next, the effect will be explained. When opening the rear door 22, when the operating lever 4 is rotated upward in FIG. 1, the rotating arm 14 is rotated in the direction of arrow A in FIG. 1 via the wire cable 6, and the L-shaped bracket is opened. 21 is pushed rearward via the rod 18 and the opening/closing arm 19 to open the rear door 22. Conversely, when closing the rear door 22, when the operating lever 4 is rotated downward, the rotation arm 14 is rotated in the direction of arrow B via the wire cable 6, and the rear door 22 is closed.

Therefore, in the case of the above rear door opening/closing device, since the operating lever 4 and the rotating arm 14 are connected by the wire cable 6, there is no need to secure a large space below the seat, and there is no need to secure a large space below the seat. There is also no need for attachment (support) of coupling means. Further, when opening the rear door 22, the reaction force acts as a force pushing the rotating arm 14 toward the inside of the vehicle cabin via the opening/closing arm 19 and the rod 18, but the reaction force is received by the guide member 13b. Rotating arm 1
4 rotates smoothly around the shaft support relative to the bracket 13 without being displaced, and the rear door 22 can be opened stably. Furthermore, when viewed from the pivoting position of the rotating arm 14, it is further away (below) than the supporting position of the rod 18, which is the input point of the reaction force.
Since this reaction force is received by the guide member 13b, the contact pressure of the roller 15 of the rotating arm 14 against the guide member 13b is not increased, and rolling is performed smoothly. This reduces the force required to operate the operating lever 4, improving operability.
