Abstract

PURPOSE: A reflection mirror converted into flat mirror and curved mirror is provided to be converted into the flat mirror and the curved mirror by using the flexibility of a mirror, thereby being used as the flat mirror for monitoring a rear view field in ordinary times and used as the curved mirror for assuring an wide view field in desired times. CONSTITUTION: The reflection mirror converted into flat mirror and curved mirror comprises a case, a flexible thin mirror(20) and an actuator(30). A groove is formed on a front edge of the case. The edge of the flexible thin mirror(20) is inserted into the groove of the case to be slided along the groove. The actuator(30) is mounted on the center of a rear surface of the flexible thin mirror(20) and a motion part(31) of the actuator is contacted to the rear surface. The thin mirror(20) is converted into a curved mirror by projecting the motion part(31) against the thin mirror.

Description

Convertible mirror plane to spherical mirror}

The present invention relates to a reflector which is freely converted into a flat mirror and a spherical mirror, and more particularly, to a reflector configured to freely convert from a flat mirror to a spherical mirror using the bendability of a thin film mirror.

Reflectors are used for various purposes, and the present invention relates to reflectors that are effectively applied to a room mirror or a side mirror for the driver to monitor the rear situation.

Conventionally, a vehicle room mirror or a side mirror is mostly made of a flat mirror or a structure in which a convex mirror is partially attached to prevent blind spots in a flat mirror, and as a further improved structure, as shown in Korean Patent Registration No. 0225338. Reflectors with concave and convex mirrors with different curved surfaces are installed on one side of the mirror and rotated by a drive motor to prevent blind spots.

Each of the above structures has the advantage of securing a wider rear field of view by partially adopted spherical mirrors, but has a disadvantage of narrowing the rear field of view secured by the planar mirrors at the expense of the area occupied by the plane mirrors. It is also pointed out that the magnification of the object reflected by the planar mirror and the spherical mirror is different and causes confusion.

The present invention provides a reflector that can be converted into a planar mirror and a spherical mirror using the elasticity of the mirror itself in the configuration of the reflector used for a vehicle, so that the rear view can be normally monitored by using a stabilized rearview mirror, If necessary, it was designed for the purpose of suggesting a new reflector that can be converted into a spherical mirror to secure a wide range of field of view.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a basic embodiment of the present invention, the present invention forms a groove 12 in the front border 11 of the case 10 of a certain form and the thin film mirror 20 made of a flexible material on the groove Insert the edge 21 of the) to combine the rim of the thin film mirror to perform a sliding motion on the groove, and the actuator portion 30 is installed in the center of the rear surface of the thin film mirror to perform the piston movement By contacting the rear surface of the thin film mirror is characterized in that the central portion of the thin film mirror is protruded when the advancing of the moving part is converted into a spherical mirror, and converted to a flat mirror by the elasticity of the thin film mirror when moving backward of the moving part.

The case is configured in various forms according to the purpose of use of the present invention, for example, when the present invention is applied to the room mirror has a structure in which the front body is formed of a rectangular body and an arm for attaching the vehicle is formed. When applied to the side mirror, it has a streamlined mirror housing form with the front open.

The groove 12 formed in the front edge of the case is for accommodating deformation due to the conversion of the thin film mirror, and the inserted thin film mirror is formed to have a sufficient clearance and to be slid.

The thin-film mirror 20 is a mirror formed with a reflective surface on a thin metal plate or a flexible plastic plate. The thin film mirror 20 is projected into a spherical shape centered on the center as the edge is supported and is converted into a spherical mirror having a wide reflection angle. If the pressing force is removed, it is returned to its original state and has a characteristic of returning to the flat mirror.

The actuator is implemented in various forms as a driving device for providing a conversion force by pressing the thin film mirror.

2 is an embodiment in which an actuator in the form of a hooking switch using the spring force of the spring 32 is applied, and when the surface of the thin film mirror is lightly pressed, the lock 33 is released and the motion portion protrudes forward by the spring force. While pressing the back of the thin film mirror and pushed out, the center of the thin film mirror is protruded into a spherical shape.

In this state, when the surface of the thin film mirror is pressed again, the spring is compressed and the lock is applied to maintain the retracted state, and the thin film mirror is restored to the plane by its elasticity and converted into a flat mirror.

The actuator may be configured to be electrically driven.

As an embodiment of the electrically driven actuator, a solenoid switch of a general type can be used, and in this case, it is possible to freely convert from a flat mirror to a spherical mirror and a spherical mirror to a flat mirror by protruding or returning a moving part by the switch.

Another embodiment of the electrically driven actuator forms a gear 34 in the moving part as shown in FIG. 3 and couples the gear 36 to the gear of the forward and reverse motor 35 to the shaft of the motor. According to the drive is configured to adjust the spherical angle of the thin film mirror by moving forward and backward.

In the above embodiment, the protruding length of the moving part can be freely changed by the driving of the motor, thereby allowing the radius of the spherical mirror to be arbitrarily adjusted. Accordingly, the wide angle of the spherical mirror is changed to enable rear view monitoring from the narrow angle to the wide angle.

4 shows an embodiment in which the present invention is applied to the side mirror, and can be easily applied by installing the reflector a according to the present invention on the front surface of the mirror housing 40 which forms a streamlined shape.

On the other hand, the reflector according to the present invention can be attached to the side mirror configured to adjust the reflection angle as it can be made at the same time to adjust the wide angle and reflection angle of the thin film mirror, in this case, the reflector according to the present invention attached to the existing reflector mounting It is simply installed.

The present invention by the above configuration is described as a form applied to a room mirror or a side mirror of a vehicle requiring rear view security, but is not limited to the field of application having a variety of applications.

The present invention is configured to convert the spherical angle of the reflector by the actuator to be freely converted into the plane mirror and the spherical mirror, and is applied to the side mirror or the room mirror of the vehicle to secure the rear field of view by the plane mirror and secure a wide range of field of view by the sphere mirror. In addition, a single reflector is used to convert the spherical mirror and the flat mirror to each other, thereby making it convenient to use without confusion or field of view of the image that occurred when using a convex mirror for preventing blind spots.
