  FIG. 10 is a view showing an example of the above-described automatic door opening and closing device for a vehicle, and is a schematic view when the passenger compartment is viewed from the rear of the vehicle. FIG. 11 is a cross-sectional view taken along line AA in FIG. In FIG. 10, reference numeral 101 denotes a rod, and the distal end side of the rod 101 is connected to a back door (not shown). Reference numeral 102 denotes an arm, and the base end side of the arm 102 is connected to a rotation shaft (also reference to 104) of a motor (see reference numeral 103 in FIG. 11), and the distal end side thereof is the base end of the rod 101. It is connected to the.

Further, reference numeral 112 shown in FIG. 11 is a body outer panel, and 113 is a body inner panel. The outer panel 112 and the inner panel 113 constitute a body panel 111.
The motor 103 is disposed between the inner panel 113 and the quarter trim 114 as a trim member. By covering the motor 103 with the quarter trim 114 in this manner, the motor 103 is exposed in the vehicle interior. It is possible to improve the appearance. In the figure, reference numeral 115 denotes a weather strip for maintaining airtightness in the vehicle.

  As shown in FIG. 10, a flexible member (rubber part) 117 is provided in an opening 116 (illustrated) between the inner panel 113 and the quarter trim 114. The rubber part 117 is formed with a slit 118 along the rotation trajectory (swinging trajectory) of the arm 102, whereby the arm 102 can be moved along the slit 118 and opened from the rear of the vehicle. The parts and structure inside 116 (link mechanisms such as the motor 103 and the arm 102) cannot be seen, and the appearance is improved.

However, as the arm 102 moves, the rubber part 117 is deformed. Therefore, as shown in FIG. 11, if the rubber part 117 is turned over at the slit 118, the internal structure can be seen. .
The present invention was devised in view of such problems, and provides an automatic door opening and closing device for a vehicle door that can prevent the appearance of parts and structures in a quarter trim and improve the appearance. For the purpose.

  For this reason, an automatic opening / closing device for a vehicle door according to the present invention includes a drive source that is held by a vehicle body and automatically opens and closes the door of the vehicle body, one end is connected to a rotation shaft of the drive source, and the other end is a link member. An arm connected to the door through, a trim member that covers the drive source and one end peripheral portion of the arm, and has an opening from which the other peripheral portion connected to the link member of the arm protrudes, A cover member made of an elastic body that closes the opening and has a slit formed along the swinging trajectory of the arm, and the cover member is formed on the outer side in the vehicle body width direction than the slit. 1 襞 and a second ridge formed on the drive source side of the first ridge and disposed substantially parallel to the first ridge, the tip of the second ridge being the first ridge Projects toward the rocking locus side of the heel It is characterized by being formed as (claim 1).

  In addition to the above-described configuration, the automatic door opening / closing device for a vehicle according to the present invention is a back door that is provided at the rear of the vehicle body and that opens and closes about a substantially horizontally disposed shaft. (Claim 3).

According to the automatic opening / closing device for a vehicle door of the present invention, it is possible to reliably prevent the inside of the first trim member from being seen with a simple configuration and to improve the appearance (claim 1). .
Further, since the width of the opening can be reduced with a simple configuration, even if the drive source and the first panel member protrude toward the vehicle interior when the door is opened, the first trim member moves toward the vehicle interior. The protruding impression can be visually weakened, and there is an advantage that the appearance and aesthetics are improved (claim 2).

  Further, when the door is a back door, there is an advantage that the appearance of the passenger compartment from the rear of the vehicle can be improved (claim 3).

  1 is a schematic cross-sectional view showing the main part of the automatic door opening / closing device for a vehicle door according to one embodiment of the present invention. FIG. FIG. 2 is a rear view, FIG. 3 is a left oblique rear view, FIG. 4 is a right oblique rear view, and FIG. 5 is a right oblique rear view, with the door closed. FIG. 6 is an enlarged view of FIG. 4, and FIGS. 7 to 9 are diagrams for explaining the effects of the present invention. 1 corresponds to the AA cross section in FIG. 10 which has already been described, and corresponds to FIG.

First, the structure of a door to which the present invention is applied will be briefly described. As shown in FIGS. 2 to 6, in this embodiment, the vehicle 100 has a wagon (or hatchback) type body, and a door (back door, tailgate, or hatch gate) (not shown) is provided at the rear of the vehicle. Is provided.
Further, the back door and the vehicle 100 are connected via a hinge mechanism (not shown) provided at the upper part of the door opening, and can be rotated upward about a rotation shaft provided substantially horizontally. Has been.

  The back door is configured to be automatically opened and closed using a drive source such as a motor 3 (see FIG. 1). The motor 3 is provided in the vicinity of the left rear pillar 19 of the vehicle 100 shown in FIGS. 2 to 3, and as shown in FIG. 1, the drive shaft from the motor 3 (or the driving force from the motor 3 is decelerated). The motor 3 is disposed so that the output shaft of the speed reduction mechanism is substantially horizontal in the vehicle width direction (more specifically, the rotation shaft 4 of the motor 3 and the rotation shaft of the hinge mechanism are parallel). Yes.

The motor 3 and a back door (not shown) are connected via a rod (link member) 1 and an arm 2 as shown in FIGS. Specifically, the distal end side of the rod 1 and the back door are connected, and the proximal end side of the rod 1 and the distal end (other end) side of the arm 2 are connected.
Moreover, the base end (one end) side of the arm 2 is connected to the rotating shaft 4 as shown in FIG. The rotating shaft 4 and the arm 2 are fixed so as not to rotate relative to each other, and when the motor 3 is operated, the arm 2 draws a rotation locus (oscillation locus) as indicated by a broken line in FIG. Further, the rod 1 and the arm 2 are connected so as to be swingable so as to allow relative rotation, and the back door and the rod 1 (not shown) are also connected so as to be capable of relative rotation.

Incidentally, reference numeral 12 shown in FIG. 1 denotes a body outer panel of the vehicle 100, and 13 denotes a body inner panel. The outer panel 12 and the inner panel 13 constitute a body panel 11.
The motor 3 is attached to the inner panel 13 via a bracket (not shown). Further, the base end portions of the motor 3 and the arm 2 are covered with a quarter trim (first trim member) 14, and thus the motor 3 is exposed to the vehicle interior by covering the motor 3 with the quarter trim 14. Is preventing.

  The quarter trim 14 has an opening 16 formed along the swinging locus of the arm 2, and the periphery of the tip of the arm 2 protrudes from the opening 16. In addition, a rubber component (a cover member that closes the opening 16) is used for the purpose of improving the appearance by preventing the opening 16 from seeing components (such as a motor) and structures in the quarter trim 14 from behind. A flexible member) 17 is provided.

Further, the rubber component 17 is formed with a slit 18 along the rotational movement locus (swinging locus) of the arm 2, so that the arm 2 can move along the slit 18. In the figure, reference numeral 15 denotes a weather strip for maintaining airtightness in the vehicle.
Incidentally, as shown in FIGS. 1 and 4 to 6, a trim member (second trim member) 20 is also provided between the inner panel 13 and the quarter trim 14. As shown in FIG. 1, the trim member 20 is formed from the position close to the inner panel 13 and the weather strip 15 of the vehicle 100 (that is, the back door opening edge) toward the swing locus of the arm 2. A wall surface 21 and a second wall surface 22 which is formed continuously with the first wall surface 21 and is substantially parallel to the swing trajectory of the arm 2 are configured. That is, the first wall surface 21 is formed from the inner panel 13 toward the vehicle interior, and is connected to the second wall surface 22 at a position close to the swing locus of the arm 2. In the present embodiment, for example, the first wall surface 21 is formed in such a direction that the swing trajectory of the arm 2 and the first wall surface 21 are substantially orthogonal, that is, in a direction substantially along the vehicle width direction.

As shown in FIGS. 1 and 6, a portion (opposing portion) 22 a of the second wall surface 22 that faces the edge 16 a of the opening 16 is opposed to the edge 16 a of the opening 16 of the quarter trim 14. Are formed to be parallel to each other.
Further, the facing portion 22a is formed with a certain width, and an end portion (base end portion) 17c on the second wall surface 22 side of the rubber component 17 is fixed to the facing portion 22a. Note that both the facing portion 22a of the second wall surface 22 and the edge portion 16a of the opening portion 16 are straight when viewed from the rear (more specifically, as viewed from the direction orthogonal to the rotation axis 4). Is formed. This is because the swing locus of the arm 2 is a straight line in the rear view, and the opposing portion 22a of the second wall surface 22 and the edge portion 16a of the opening 16 are formed along the swing locus. Because.

  Next, the main part of the present invention will be described. As shown in FIG. 1, the rubber component 17 as a cover member has a double structure, and a first rubber 17a formed outside the opening 16; And a second rubber 17b formed inside the opening 16 (that is, formed on the motor 3 side). Further, the first rubber 17a and the second rubber 17b are connected at the base end portion 17c and are integrally formed.

Furthermore, the first rubber 17a is (the plane of FIG. 1 above; first fold) first site formed toward the body panel 11 side (vehicle width direction outside) from the slit 18 and 17a _1, quarter from the slit 18 The second portion (the lower surface in FIG. 1) 17a ₂ formed toward the panel 14 side.
Further, no slit or the like is formed in the second rubber (second rod) 17b, and the tip side is free (free end). The second rubber 17b is formed in parallel to the first rubber 17a.

Further, as shown in FIG. 1, the second rubber 17b is set to have a larger width dimension than the first portion 17a ₁ of the first rubber 17a, and the tip of the second rubber 17b is the first rubber. It is configured to protrude to the swing trajectory side of the arm 2 than the first end portion 17a ₁ of 17a. That is, the tip of the first portion 17a ₁ does not reach the position exceeding the swing locus by the slit 18 formed at the substantially central position of the swing locus of the arm 2, but the tip of the second rubber 17b. The part is formed so as to reach a position exceeding the swing locus.

Therefore, at the position where the arm 2 and the second rubber 17 b actually intersect, the second rubber 17 b is surely brought into contact with the arm 2 and the second rubber 17 b is deformed along the arm 2.
The rubber part 17 has a double structure as described above, and the tip of the second rubber 17b formed on the motor 3 side protrudes toward the swing locus side of the arm 2 so that the arm 2 temporarily uses the first rubber. Even when 17a is turned over, the second rubber 17b is deformed while being in contact with the arm 2, so that it is possible to reliably prevent the components in the quarter trim 14 from being seen through the slit 2, The appearance can be improved.

  2, 4, and 6, a notch 18 a is formed slightly below the middle of the slit 18 of the rubber part 17. As shown in FIG. 5, the notch 18a is provided at a position where the rod 1 is located when the back door is closed. That is, normally, the back door is overwhelmingly longer than the open time, so that the door should be closed so that unnecessary deformation does not occur in the rubber part 17 in such a closed state. The notch 18a is provided at the place where the rod 1 is located in the closed state. When the door is closed, the arm 2 is stored in the quarter trim 14.

As shown in FIGS. 4 to 6, in the present embodiment, the quarter trim 14 is composed of two parts, a quarter trim upper 14a and a quarter panel lower 14b, and the boundary between such two parts 14a and 14b. Although the above-described notch 18a is formed, the present invention is naturally applicable even if the quarter trim 14 is an integrally molded product.
Since the automatic door opening and closing device for a vehicle door according to an embodiment of the present invention is configured as described above, when the door is closed, the rod 1 is notched in the rubber part 17 as shown in FIG. It is in the state which entered 18a.

  From this state, for example, the driver operates a switch provided near the driver's seat, operates a switch provided on the portable key, or gently pulls the door handle of the back door, thereby The latch mechanism (not shown) is released, and the driving force of the motor 3 is transmitted to the back door via the arm 2 and the rod 1 to open the back door.

  That is, when the motor 3 is operated and the rotating shaft 4 rotates, the arm 2 rotates about the rotating shaft 4 and moves the slit 18 upward in the figure. When the door is opened in accordance with the operation of the arm 2 and the door is fully opened, the operation of the motor 3 is stopped and the open state of the door is maintained. 2 to 4 and 6 show the state of the arm 2 and the rod 1 when the door is open.

  In the state where the back door is opened in this manner, in the present apparatus, it is possible to prevent parts such as the motor 3 disposed in the quarter trim 14 from being seen from the slit 18 and to improve the appearance and aesthetics. For example, FIG. 7 is a diagram showing a state in which the second rubber 17b is not provided on the rubber component 17, but in this case, the components in the quarter trim 14 are slightly visible from the slit 18 as shown. Therefore, it will impair the appearance. In such a case, since dust enters the quarter trim 14 from the slit 18, the quarter trim 14 has a low dust resistance, and it is necessary to individually improve the dust resistance of the internal components.

FIG. 8 is a diagram showing a state where the first rubber 17a is formed only by the first portion 17a ₁ and the second portion 17a ₂ is omitted, although the second rubber 17b is provided. Also in this case, the parts in the quarter trim 14 are visible from the outside of the door, which impairs the appearance. Further, in this case, since a gap having a size larger than that of the slit 18 is formed, the appearance is further impaired as compared with the case shown in FIG. 7, and the dustproofness is further lowered.

FIG. 9 is a view showing a state in which the rubber component 17 is configured by only the first portion 17a ₁ of the first rubber 17a. In this case, the appearance and dustproofness are further deteriorated as compared with the case shown in FIG.
On the other hand, according to the present apparatus, as shown in FIG. 6, since it is possible to reliably prevent the internal parts from being seen, there is an advantage that the appearance and aesthetics are greatly improved, and the dust resistance is also greatly improved. There is an advantage of doing.

Further, in this state where the back door is open, the present apparatus does not visually give the impression that the quarter trim 14 protrudes toward the vehicle interior side, and the appearance can be improved in this respect as well.
That is, according to the present invention, the trim member (second trim member) 20 is provided between the quarter trim (first trim member) 14 and the inner panel (body panel) 13. Since the first wall surface 21 substantially orthogonal to the swing locus and the second wall surface 22 substantially parallel to the swing locus of the arm 22 are formed, as shown in FIG. The width dimension of 16 (the width dimension of the rubber part 17) can be minimized, and as a result, the impression that the quarter trim 14 protrudes into the vehicle visually can be eliminated when the back door is open. .

On the other hand, as shown in FIG. 11, when the quarter trim 114 is simply provided and the opening 116 is simply closed with the rubber part 117, the width of the opening becomes large, which is visually compressed. A feeling arises and the impression that the quarter trim 114 protrudes largely in the vehicle interior side is given.
As described above in detail, according to the vehicle door automatic opening and closing device according to the embodiment of the present invention, when the door is opened, the components such as the motor 3 disposed inside the quarter panel 14 can be seen. It can be reliably prevented, and the appearance and aesthetics are greatly improved. In addition, dust resistance is greatly improved. Further, as described above, this apparatus has an advantage that the cost is hardly increased by the simple configuration in which the rubber component 17 is doubled.

Even if the motor 3 or the quarter panel 14 protrudes toward the vehicle interior when the door is opened, the impression that the quarter panel 14 protrudes toward the vehicle interior can be visually weakened. There is an advantage of improvement.
Moreover, since the opening part 16 is obstruct | occluded with the rubber component 17 in which the slit 18 was formed, the opening part 16 can be obstruct | occluded, without inhibiting rocking | fluctuation of the arm 2. FIG. Thereby, since the components in the opening part 16 become invisible, there is an advantage that the appearance is improved.

Further, according to the present embodiment, it is only necessary to add one resin component (trim member) 20 between the quarter panel 14 and the inner panel 13, so that an increase in cost can be suppressed as much as possible, and the appearance is inexpensive. Can be improved.
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the present invention is not only applied to a back door, but can be widely applied to a door that opens and closes a hinged door using an arm or a link mechanism.

In the present embodiment, the case where the first rubber 17a and the second rubber 17b of the rubber component 17 are integrally formed has been described. However, the first rubber 17a and the second rubber 17b may be separately formed. In the present embodiment, the first rubber 17 a is formed from the first part 17 a ₁ and the second part 17 a ₂ , but the second part 17 a ₂ may be separated from the rubber part 17.
