Description

Side mirror angle adjuster

The present invention relates to a side mirror, and more particularly, to an angle adjusting device of an outside mirror in which the angle adjusting structure of the outside mirror is a five-point supporting structure, which strengthens the supporting structure and increases the amount of the angle range.

In general, the side mirrors commonly used include a pivot holder 140 pivotably installed at the central axis of the glass holder 110 that rotates as the actuator 120 in the mirror housing 100, as shown in FIG. 1. The upper and lower angle adjustment structure 130 of the 2nd, 3rd point should be provided in the substantially orthogonal range about this. The vertical adjustment structure 130 is provided with driving means for pushing up and down the rear main surface of the glass holder 110 in the first and second positions, respectively. The first driving means for moving up and down adjusts the up and down angle by raising or lowering the rear surface of the glass holder, and the second driving means is located on the rear of the glass holder at an approximately right angle with respect to the pivot 140 to adjust the up and down angle. By adjusting the angle of the glass surface.

Such a structure has the pivot 140 as the first point, the first driving means 130 as the second point, and the second driving means (not shown in the drawings and omitted) as the third point. 3-point fixed structure.

The conventional side mirror driving method has problems of incompleteness of the support point and shaking due to play during vertical angle adjustment.

The present invention is more robust by improving the angle adjustment structure of the conventional three-point driving method, the tremor is significantly improved during driving, giving accuracy to rear-projection projection, smooth rotational movement and at the same time provides a delicate angle adjustment function, Its purpose is to provide a structure that reduces costs while making the angular range more possible.

An object of the present invention for achieving the above object is a glass holder formed on the rear of the corresponding pair of support pairs of different lengths, and rotatably riveted from the first support of the glass holder, between And a first supporting member which forms a gear on the outer circumferential surface while forming a bridge and is rotatably rotatably formed on the second support of the glass holder, between which forms a semi-circular bridge and forms a gear on the outer circumferential surface. At the same time, a second support member having a diameter smaller than the first support member, and a first driving gear which is placed below the first support member to determine a first direction of the glass; And a second drive gear mounted in the first support member and abutting under the second support member.

Hereinafter, an embodiment of the present invention based on the accompanying drawings.

2 is a cross-sectional view of the present invention and FIG. 3 is a cross-sectional view taken along line B-B of FIG. 2.

According to the above drawings, the present invention consists of a mirror housing 300, a glass holder 200, and driving means installed between the mirror housing 300 and the glass holder 200.

The glass holder 200 forms the center of rotation of the glass holder 200 by installing a pivot 230 at a rear center thereof, and becomes a first fixed point.

The second, 3, 4, 5 fixed point is further formed behind the glass holder 200.

That is, the second, third, fourth, and fifth fixing points may include a first support part 232 and a second support part of the glass holder 200 in which two semicircular bridges having different diameters cross each other and are supported. 234) at each end.

The first support part 232 and the second support part 234 are divided in the circumferential direction by 90 ° based on the first fixing point, and their lengths are also different. The divided two semicircular bridges of different diameters are referred to as a first support member 210 and a second support member 220, respectively.

The first driving means 240 is connected to the bottom of the first support member 210, and the second driving means 250 is connected to the bottom of the second support member 240 as a gear. These drive means are also called actuators.

The first support member 210 is bent in a semicircle between the first support portions 232 facing each other from the rear of the glass holder 200 is supported in the form of a bridge. A gear 212 is formed on the main surface of the bridge-shaped first support member 210. The worm gear 242 of the first driving means 240 is in contact with the gear 212, the worm gear 242 is connected to the drive motor 244 is driven.

The second support member 220 is bent in a semicircle between the second support portions 234 facing each other from the rear of the glass holder 200 is supported in the form of a bridge. A gear 222 is formed on the main surface of the bridge-shaped second support member 220. The worm gear 252 of the second driving means 250 is in contact with the gear 222, the worm gear 252 is connected to the drive motor 254 is driven. The first support member 210 is formed of a semi-circular bridge of larger diameter than the second support member 220.

The first and second driving means 240 and 250 are blocked by the lower casing 310 and the upper casing 320 extending from the mirror housing 300, and the external glass holder 200 The bridge is connected between the first and second support members 210 and 220 of the type. The first and second sealing pads 330 and 340 are formed in the guide holes of the casings 330 and 340 to reduce the gap between the supporting members 210 and 220.

The present invention made as described above is formed on the rear circumferential line of the glass holder 200, the support members 210, 220 of two different sizes of semicircular bridges divided into vertical and horizontal cross-sections, and the support members 210 ( Worm gears 242 and 252 driven by the driving motors 244 and 254 are connected to the gears 212 and 222 on the main surfaces of the main surfaces simultaneously or simultaneously to the support members 210 and 220. As the driving force is individually given, the vertical and horizontal angles of the glass holder 200 are adjusted.

For example, when the first driving motor 244 is driven in FIG. 2, since the first worm gear 242 is connected to the gear 212, the support member 210 is operated left and right in the direction of the arrow, and the second driving motor is operated. When driving the 250, the operation in the direction of the arrow shown in FIG.

As such, the present invention is firmly fixed by the first fixing point of the center of the glass holder and the four fixing points to which the two semi-circular bridge-type supporting members are fixed, compared to the conventional side mirror angle adjusting method of the three fixing points. The error rate of vertical and horizontal angle adjustment of the holder is improved, and the angle adjustment structure of the conventional three-point driving method is improved to maintain more robustness, and the tremor is significantly improved during driving, giving accuracy to rear-view projection and smoothing the rotational movement. At the same time, it provides a delicate angle adjustment function and provides an angle adjustment structure with an increased angle range amount.
