Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle mirror device having an improved support structure.

[0002]

[Prior Art]

 For example, as a support structure for an outer mirror for a vehicle, a spherical bearing mechanism is generally used conventionally. In this structure, a spherical journal is formed at the tip of a stay fixed to the vehicle body, and a spherical body bearing for receiving the spherical journal is integrally provided on the plastic body of the mirror body. The spherical bearing portion on the mirror body side is formed in two parts, and each divided part is tightened with a screw with the spherical journal sandwiched between them.

[0003]

[Problems to be solved by the device]

 However, in the above configuration, since the mirror body is supported by the tip of the stay at one point, there is a problem that the mirror body is likely to vibrate due to vibration or wind pressure when the vehicle is running. When the mirror body vibrates, the visibility in the rear field of view is reduced, and improvement of this point has been conventionally demanded.

The present invention has been made in view of the above circumstances. The purpose thereof is to provide a mirror device for a vehicle, which can firmly fix the mirror body to the stee and prevent its vibration.

[0005]

[Means for Solving the Problems]

 The mirror device of the present invention includes a stay mounted on the vehicle side, a mirror body, a first bearing mechanism of a spherical bearing type provided between the tip of the stay and the mirror body, and a mirror body. The second bearing mechanism is characterized in that it is provided with a second bearing mechanism that holds a portion of the stay that is located closer to the base side than the tip end of the stay by sandwiching it between flat surfaces facing each other.

[0006]

[Action]

 Since the mirror body is supported at two points, the first bearing mechanism at the tip of the stay and the second bearing mechanism located at the base side of the tip of the stay, the mirror body and the stay are supported by two points. The force acting on is distributed in two places.

Further, since the first bearing mechanism is a spherical bearing type, the mirror body is rotatable in all directions with respect to the stay. On the other hand, since the second bearing mechanism is configured so that both sides of the stay are simply sandwiched by the flat surfaces, the mirror body is centered around the rotation of the stay around the axis and the spherical bearing (first bearing mechanism). Rotation is permitted. Therefore, while the mirror body is supported at two points, it is allowed to rotate in the left-right direction and the vertical direction with respect to the stay, and in the end, the mirror body can be set to a desired angle.

[0008]

[Effect of the device]

 As described above, according to the mirror device of the present invention, the mirror body is supported at two points through the first and second bearing mechanisms, so that the force is dispersed and the fixed state is ensured. Therefore, the vibration of the mirror body can be surely prevented. In addition, as described above, the mirror body is allowed to rotate in both the left and right directions and the up and down directions with respect to the stay even though it is supported at two points, so that the mirror body can be set at a desired angle. it can.

【Example】

 An embodiment in which the present invention is applied to an outer mirror for a vehicle will be described below with reference to the drawings.

As shown in FIG. 8, the overall schematic structure is a structure in which a mirror body 2 is attached to the tip of a stay 1. The stay 1 is fixed to a vehicle body (not shown), and a spherical journal 3 is formed at the tip of the stay 1 via a tapered taper portion 1a as shown in FIG. The center of the spherical journal 3 is on the axis of the stay 1.

On the other hand, the mirror body 2 is constructed by attaching a mirror glass 5 to a plastic mirror body 4. In this mirror body 4, a pair of holding portions 7 are integrally formed in the lower part of the rear surface so as to face each other (see FIG. 2), and a concave portion 7 a having a hemispherical portion is formed on the facing surface of each holding portion 7. ing. These recesses 7a jointly wrap the spherical journal 3 of the stay 1 from the left and right, and in this state, the holding parts 7 are fastened to each other by screws 8. As a result, a spherical bearing type first bearing mechanism 9 is formed between the tip of the stay 1 and the mirror body 2, and the mirror body 2 is rotatable in all directions with respect to the tip of the stay 1. ing.

Next, as shown in FIG. 3, a pair of sandwiching pieces 10 are integrally formed on the back surface of the mirror body 4 below the sandwiching portion 7 of the first bearing mechanism 9 so as to face each other. Is made. The sandwiching pieces 10 each have a flat opposing surface, and a reinforcing plate 11 made of a steel plate and a cushioning plate 12 made of a plastic are sequentially fitted inside. As shown in FIGS. 5 and 6, the reinforcing plate 11 and the buffer plate 12 are both U-shaped as a whole, and the former has an engaging piece 11a which engages with the holding piece 10 and prevents the shift. The latter is integrally formed with an engaging piece 12a which engages with the reinforcing plate 11 to prevent the displacement. The reinforcing plate 11 and the buffer plate 12 are attached to the inside of each sandwiching piece 10 so as to be stacked in order, and the stay 1 is sandwiched between the sandwiching pieces 10 via the reinforcing plate 11 and the cushioning plate 12. ing. In this state, a tightening screw 13 is provided penetrating the tip of each sandwiching piece 10, and both sandwiching pieces 10 are tightened by this screw 13. As a result, a second bearing mechanism 14 that holds the portion of the stay 1 located on the base side of the tip end by sandwiching the flat surfaces facing each other from both sides is formed in the mirror body 2. A resin sleeve 15 is provided on the tightening screw 13 to prevent interference with the stay 1 and to prevent excessive tightening, and the mirror body 4 covers the first and second bearing mechanisms 9 and 14. The bearing cover 16 of is detachably attached.

According to the above configuration, the mirror body 2 is in a state of being supported by the stay 1 at the two points of the first and second bearing mechanisms 9 and 14. Therefore, the force acting between the mirror main body 2 and the stay 1 is dispersed at two places, as compared with the one-point support type mirror device in which the mirror main body is supported by only one spherical bearing. It is possible to prevent the visibility of the rear view from being deteriorated due to the mirror body 2 vibrating even when the vehicle body vibrates or wind pressure is generated when the vehicle is traveling.

Moreover, while the mirror body 2 has the two-point support structure as described above, it is possible to obtain a sufficient degree of freedom in adjusting the angle of the mirror body 2 as follows. That is, with respect to the rotation around the axis of the stay 1, the centers of the first and second bearing mechanisms 9 and 14 are on the same axis, so that the mirror body 2 is moved to the stay 1 as shown in FIG. It is rotatable about the axis A in the direction of arrow a (left-right direction). Further, since the second bearing mechanism 14 has a structure in which the stay 1 is sandwiched from the left and right by flat surfaces (buffer plates 12), the stee 1 can be displaced between the buffer plates 12. Therefore, as shown in FIG. 7, the mirror body 2 is rotatable in the direction of arrow b (vertical direction) about the axis B perpendicular to the plane of the drawing through the center of the spherical journal 3 of the first bearing mechanism 9. Is becoming In this way, the mirror body 2 is rotatable about two axes orthogonal to each other, so that the mirror glass 5 can be oriented in a desired direction, and the rear visual field can be adjusted freely.

It should be noted that the present invention is not limited to the above-described embodiment, but the following modifications are possible.

(1) In the above embodiment, the spherical journal 3 is formed on the side of the stay 1, but conversely, the spherical journal is integrally fixed to the side of the mirror main body 2 and the spherical journal is formed on the side of the stay 1. It may be configured to provide a spherical bearing for holding. (2) In the above embodiment, an example in which the invention is applied to an outer mirror of a vehicle is shown, but the invention is not limited to this, and the invention is also applied to an inside mirror for an inside of a vehicle, an under mirror for seeing a rear lower side of a large vehicle such as a bus, and the like. be able to.
