Abstract

(57) [Summary] (with modifications) [Purpose] To prevent chatter that occurs on the mirror surface of an inner mirror whose mirror surface can be adjusted by an actuator. [Structure] An elastic clamping member 5 is disposed on one of the frame 2 and holder mirror 4 of the inner mirror whose mirror surface angle is adjusted using an actuator 3, and a convex engagement member is disposed on the other. , a structure in which they are fixed so that they can be inserted and removed. [Effect] While enabling angle adjustment using the actuator, it prevents chattering on the mirror surface and provides a clear view.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention mainly relates to a vibration prevention structure that prevents chattering of the inner mirror. Ru.

0002

[Conventional technology]

Conventionally, the mirror angle of the inner mirror was adjusted by grasping the mirror housing. In many cases, it is a manual type, but in recent years electric motors have been introduced that allow adjustment to be performed remotely. In some cases, the mechanism is provided inside the mirror housing. Although illustrations are omitted, there are many examples. The holder mirror is supported by an actuator, and the four-way mirror is placed around the driver's seat. By driving the electric motor attached to the actuator using a switch etc., the holder is By adjusting the direction of the dermal mirror, the mirror surface can be adjusted in any direction.

0003

[Problem that the idea aims to solve]

However, the horizontally long holder mirror has an actuator at its center. There are no supporting members at the left and right positions away from the center. It is supported in an unstable state and tends to shake easily, resulting in frequent chatter. Therefore, The present invention is designed to engage and fix the left and right parts of the holder mirror to the frame in a freely insertable and removable manner. This provides a vibration damping structure that prevents chatter from occurring.

0004

[Means to solve the problem]

The present invention is based on the left side of the actuator located approximately in the center of the horizontally long frame. Elastic holding members are provided on both sides of the holder mirror, and a protrusion is provided on the back of the holder mirror. an engaging member having a shape of This is a vibration-preventing structure for the inner mirror, which is characterized by the fact that it has a built-in structure.

[0005]

[Effect of invention]

Conventionally, the holder mirror was engaged so that it could move at the actuator fitting part. However, other parts of the holder mirror are suspended in the air, and the present invention does not allow the above-mentioned fitting. The floating part of the holder mirror, which is formed into a horizontally long wing shape with the joint in the center. Further, a protruding engaging member is provided which is removably inserted into and fixed to the holding member. Hold the holder mirror at the actuator fitting part and the parts on both sides of it. This eliminates side-to-side vibration, increases the stability of the mirror surface, and prevents chatter. Stop. Furthermore, the holding member and the engaging member are fixedly attached to each other so that they can be freely inserted and removed. The holder mirror moves smoothly even when adjusting the mirror angle using the actuator. be able to.

【Example】

FIG. 1 is a partially cutaway perspective view of an embodiment of the present invention. Not shown The inner mirror 1 supported by a pivot by normal means is a horizontally long mirror. - Approximately the center of the frame 2, which is arranged inside the housing and is made of a rigid member. A holder that is fitted to the actuator 3 arranged in the holder to enable adjustment of the mirror angle. It is equipped with a mirror 4.

[0007] The vibration prevention structure of the present invention connects the frame 2 and the holder mirror 4 to an actuator. It has a structure that fits with the frame 2 not only at the fitting part of the eta 3 but also at other places. An example of this is shown below. That is, the act Holding members 5 having a substantially U-shape in plan are disposed on both left and right sides of the tuator 3. This clamping The member is made of an elastic member such as a metal or resin plate spring, for example. As shown in the figure, it narrows toward the tip, and the tip is slightly narrowed. The projecting engagement member is expanded so as to be easily received.

[0008] On the other hand, on the back side of the holder mirror 4, the aforementioned clamps are arranged on the left and right front sides of the frame 2. An engaging member 6 protruding like a pin is disposed at a position facing the member 5. In addition, a The mating part between the actuator 3 and the holder mirror is fixed using conventional general-purpose means. The explanation is omitted.

[0009] When assembling the mirror, the pins are fixed so that there is no problem when adjusting the mirror surface. The engaging member 6 has a shape such that the engaging member 6 can move in the insertion/removal direction within the holding member 5. It is fitted into and fixed in the holding member 5 on the frame 2 side.

0010 The vibration prevention structure of the present invention configured as described above is effective when adjusting the direction of the mirror surface. allows the engaging member to move within the holding member while being held by the holding member. Therefore, it can be carried out easily and without any problems, and even in situations where vibration is likely to occur, it can be carried out easily and without any problems. In addition to the mating part of the actuator, there are also holder mirrors on the left and right sides of the actuator. - is held in the frame, making it possible to reliably prevent vibration from occurring.

[0011] In addition, although the elastic holding member is fixed to the frame side in the illustration, the holder mirror Needless to say, it may be attached to the side. Also, although not shown, there is a protruding engagement The present application also devised a technology in which elastic protrusions are formed on the outer periphery of the mating member, so that the clamping member does not have elasticity. include. Furthermore, both the clamping member and the engaging member may have elasticity. Needless to say.

0012

[Effect of the idea]

The present invention, as mentioned above, requires only slight changes to the conventional mechanism, that is, A novel and simple structure in which the left and right sides of the holder mirror are supported by the frame. Occurs on the holder mirror without interfering with the mirror angle adjustment using the actuator. This is an excellent idea for preventing vibrations, and is extremely useful for industrial use. .
