Definitions
- the present invention relates to a vehicle side mirror provided in a vehicle so that a driver can easily grasp the left and right road conditions.
- the vehicle is equipped with mirrors on the outside of the left and right front doors or the front left and right points of the bonnet and the inside of the car in order to allow the driver to easily understand the left and right road conditions.
- the mirror is called a room mirror or a side mirror depending on the mounting position. That is, the mirrors located outside the left and right front doors of the vehicle and the front left and right points of the bonnet are called side mirrors.
- the driver may recognize the driving direction or the speed of another vehicle traveling behind the vehicle through the side mirror while watching the front left and right sides. Therefore, the driver may maintain a safety distance with the vehicle in front and rear, and may safely pass or change lanes without disturbing the operation of other vehicles traveling behind.
- the auxiliary mirror is further mounted on the vehicle.
- the image changes rapidly while passing through the installation boundary of the auxiliary mirror and thus does not give the driver a complete rearward view, so that the two regions where the size of the rear object is constant are minimized in one side while minimizing optical distortion. It must be represented by a mirror.
- Korean Utility Model Application Publication No. 20-0288548 discloses a side mirror in which a vehicle body side portion is formed in a planar shape and an outer portion is formed in a convex curvature surface.
- Korean Utility Model Publication No. 20-0322014 discloses a side mirror that provides a planar mirror in a portion adjacent to the vehicle body and provides a convex mirror at a position relatively far from the vehicle body.
- magnification can only depend on the curvature of the outer convex mirror, and because of the characteristics of the convex mirror, the image becomes smaller and farther away toward the edges, so the distance to the rear object is lower than that of the planar mirror. This is inaccurate.
- An object of the present invention is to solve the blind spot that the driver cannot see while driving the vehicle, as well as the vehicle side mirror that allows the driver to easily predict the distance of the object with a uniform perspective through a mirror area having a constant rate of change in refractive power. In providing.
- the vehicle side mirror according to the present invention for achieving the above object is a mirror housing mounted to the outside of the vehicle, and a plurality of mirror regions are supported in the mirror housing in the horizontal direction from the inner side close to the vehicle to the outer side far from the vehicle aspheric shape It includes a mirror portion each partitioned into. Each of the mirror portions gradually increases from the inner side to the outer side, so that the refractive power is the same at the boundary of the mirror areas, and the change rate of the refractive power of at least one of the mirror areas is constant.
- the vehicle side mirror according to the present invention enables a driver to easily predict the distance of an object with a uniform perspective through a mirror area having a constant refractive index change rate while driving a vehicle.
- the side mirror for a vehicle according to the present invention can simultaneously show both near and intermediate distances and objects in a clear and close distance without distortion, widening the field of view in the outside of the mirror area to avoid blind spots as well as distortion of the image To minimize astigmatism.
- FIG. 1 is a front view of a vehicle side mirror according to an embodiment of the present invention.
- FIG. 2 is a front view illustrating the mirror unit of FIG. 1.
- FIG. 3 is a graph illustrating refractive power in a horizontal direction in the mirror part of FIG. 2.
- FIG. 4 is a graph illustrating a change rate of refractive power in the horizontal direction in the mirror part of FIG. 2.
- FIG. 1 is a front view of a vehicle side mirror according to an embodiment of the present invention.
- FIG. 2 is a front view illustrating the mirror unit of FIG. 1.
- the vehicle side mirror 100 includes a mirror housing 110 and a mirror unit 120.
- the mirror housing 110 is mounted outside the vehicle.
- the mirror housing 110 may be mounted to be folded or unfolded outside the vehicle.
- the mirror housing 110 serves to protect the mirror unit 120 from external impact and to support the mirror unit 120.
- the mirror unit 120 is supported by the mirror housing 110.
- the mirror unit 120 may be wrapped by the mirror housing 110 so that the reflective surface is exposed to the outside.
- the mirror unit 120 is divided into a plurality of mirror regions in an aspherical form, respectively, in a horizontal direction from an inner side close to the vehicle to a far outer side of the vehicle.
- Aspherical shape is similar to a loose normal distribution curve, meaning that the shape is neither spherical nor flat. Aspheric surfaces are flattened as the curvature decreases from the center to the periphery, or the curvature increases as the center is flat and toward the periphery. That is, the curvature of the aspherical lens or mirror changes from the center to the periphery, and the optical power also changes.
- the degree of such refractive power change is called an optical power rate and can be expressed as an eccentricity of an aspherical curve.
- the mirror 120 has a constant refractive index change rate of at least one mirror area among the mirror areas. Accordingly, the driver can easily predict the distance of the object with a uniform perspective through the mirror area having a constant rate of change in refractive power.
- the mirror unit 120 is formed such that the optical power of the mirror areas gradually increases from the inner side to the outer side so that the refractive power is the same at the boundary of the mirror areas.
- the refractive power refers to the degree of refraction of light by the mirror unit 120 and is represented by a diopter.
- the refractive power can be found as the inverse of the average radius of curvature.
- the mirror unit 120 gradually increases the refractive power from the inner side to the outer side, the near, intermediate, and long distance objects can be simultaneously displayed in a clear and close distance without distortion, and the vision is widened in the mirror area located outside. In addition to eliminating rent, image distortion and astigmatism can be minimized. In addition, since the mirror 120 has the same refractive power at the boundary of the mirror areas, an image jump phenomenon may be prevented from occurring at the boundary of the mirror areas.
- three mirror regions may be divided into an inner mirror region A, a central mirror region B, and an outer mirror region C.
- the inner mirror area A corresponds to the area closest to the vehicle
- the outer mirror area C corresponds to the area furthest from the vehicle.
- the central mirror area B corresponds to the area between the inner mirror area A and the outer mirror area C.
- the ratio of each width along the X-axis direction may be 4: 3: 3 in the horizontal direction. That is, the inner mirror area A may have the largest width, and the central mirror area B and the outer mirror area C may have the same width. When the area of the inner mirror area A is large, it may be advantageous to eliminate distortion of the image and inaccurate distance.
- the inner mirror area A may be configured to occupy more than half of the entire area of the mirror part 120.
- the areas of the inner mirror area A, the center mirror area B, and the outer mirror area C may be set differently according to the shape of the mirror part 120.
- the inner mirror region A has an increased refractive power along the horizontal X-axis direction from the inner edge to the boundary with the central mirror region B, and thus at the boundary with the central mirror region B.
- the refractive power may be the same.
- the refractive power may gradually increase. As a result, it is possible to prevent the hopping phenomenon from occurring at the boundary between the inner mirror area A and the central mirror area B.
- FIG. In the central mirror area B the refractive power increases along the X-axis direction from the boundary with the inner mirror area A to the boundary with the outer mirror area C so that the refractive power at the boundary with the outer mirror area C may be the same. Can be.
- the refractive power may gradually increase.
- the outer mirror region C may increase in refractive power along the X-axis direction from the boundary with the central mirror region B to the outer edge. In the outer mirror region C, the refractive power may gradually increase.
- the inner mirror area A can be shown without distorting the image of the object in the near field.
- the central mirror area B can be shown without distorting the image of the object at an intermediate distance.
- the outer mirror area C can be shown without distorting the image of a remote object. Accordingly, the mirror unit 120 may simultaneously show both near, intermediate, and remote objects in a clear and close distance without distortion.
- the rate of change of the refractive power of the inner mirror area A, the central mirror area B, and the outer mirror area C may be constant.
- the driver can easily predict the distance of the object with a uniform perspective through the inner mirror area A, the central mirror area B, and the outer mirror area C.
- the refractive index change rate of the outer mirror area C may be greater than the refractive index change rate of the central mirror area B, and the refractive index change rate of the central mirror area B may be greater than the refractive index change rate of the inner mirror area A.
- the inner mirror area A, the central mirror area B, and the outer mirror area C may have the same refractive power change rate. That is, the mirror portion 120 may have a constant refractive index change rate in the horizontal direction over the entire area.
- the refractive index change rate of the inner mirror area A is greater than the refractive index change rate of the central mirror area B or the outer mirror area C, or the refractive index change rate of the central mirror area B is the outer mirror area C.
- the inner mirror area A, the central mirror area B, and the outer mirror area C may have different refractive power change rates.
