Description

Technical Field

[0001] The present invention relates to an optical device, and in particular to a high-definition zoom lens capable of magnifying the image of an object. Background Art

[0002] Existing reading magnifiers use the lens magnification principle to magnify books or mobile phones so that users with poor eyesight can easily read them.

[0003] For example, Patent Publication No. CN209731365U of the People's Republic of China discloses a mobile phone magnifier comprising a rectangular base, a support plate disposed distally from the base, and a magnifying glass disposed proximally and parallel to the support plate. A user can place their phone against the support plate and view the phone through the magnifying glass, thereby magnifying the phone's image.

[0004] However, when viewing a mobile phone through the mobile phone magnifier, the user has to get quite close to the magnifying glass to see clearly, which can easily cause the head to tilt forward, leading to shoulder and neck pain, and even cervical vertebrae degeneration. Summary of the Invention

[0005] Therefore, an object of the present invention is to provide a high-definition telephoto lens that can maintain an appropriate viewing distance.

[0006] To achieve the above-mentioned object, the present invention provides a high-definition zoom lens, which is suitable for being placed or clamped on a table and used to obtain a magnified image of an object at a far side. The high-definition zoom lens includes a bracket unit and a lens base unit.

[0007] The bracket unit is suitable for being placed or clamped on the desktop. The lens base unit is arranged above the bracket unit in an up-down direction and constructs an optical path for obtaining the magnified image on the far side. The lens base unit includes an eyepiece base, a rotating shaft and an objective lens base. The eyepiece base is arranged on the bracket unit and has a reflective lens that is higher than the desktop and tilted relative to the desktop. The rotating shaft is arranged at the top of the eyepiece base and extends in a horizontal direction perpendicular to the up-down direction. One end of the objective lens base is arranged on the rotating shaft and can be flipped relative to the eyepiece base. The objective lens base has a magnifying lens located above the object in the up-down direction. The magnifying lens is used to magnify the image. The optical path is first reflected from the object to the magnifying lens, then reflected from the magnifying lens to the reflective lens, and then reflected out by the reflective lens.

[0008] The device further comprises a light source unit, which is used to provide light on the optical path.

[0009] The eyepiece base further comprises a lower shell for arranging the reflective lens, and the light source unit is arranged on a lower edge of the lower shell.

[0010] The eyepiece mount also has a lower shell for the reflective lens to be set, and the objective lens mount also has an upper shell for the magnifying lens to be set. The rotating shaft has a first pivot formed on one side of the lower shell, and a second pivot formed on one side of the upper shell and capable of rotating relative to the first pivot.

[0011] The lens holder unit further includes a photographing unit having a lens.

[0012] In which, the objective lens mount also has a side edge away from and lower than the rotating shaft. The objective lens mount can pivot relative to the eyepiece mount in an open state and a covered state. In the open state, the objective lens mount is slightly horizontal, and the side edge is slightly lower than the rotating shaft and higher than a lower edge of the eyepiece mount. In the covered state, the objective lens mount covers the eyepiece mount, and the side edge of the objective lens mount is lower than the lower edge of the eyepiece mount.

[0013] Wherein, the magnifying lens is a free-form concave mirror.

[0014] Wherein, the reflective lens is a free-form concave mirror.

[0015] The area of ​​the reflective lens is smaller than that of the magnifying lens.

[0016] The reflective lens is a trapezoid that is wide at the top and narrow at the bottom.

[0017] The bracket unit includes a base for being placed on the desktop, and a support rod extending upward from the base along the up-down direction. The support rod has a lower end fixed to the base, and an upper end opposite to the lower end and for the eyepiece lens holder to be set.

[0018] The reflecting lens and the magnifying lens form an angle between 40 and 60 degrees.

[0019] Wherein, a side edge of the magnifying lens is spaced apart from the upper surface of the object by a distance in the vertical direction, and the distance is between 40 and 60 centimeters.

[0020] The bracket unit has an adjusting member which can be adjustably mounted on the eyepiece base, and the base unit can move up and down in the up and down direction relative to the bracket unit.

[0021] The present invention is effective in that a user can place the present invention directly on a tabletop or clamp it to the edge of the tabletop, open the objective lens mount, and then place the object underneath the objective lens mount. The user can look directly into the eyepiece mount and see the magnified image on the reflective lens. Because the magnified image is a proportional magnification of the object and is located on the far side (i.e., the reflective lens), the user can clearly see the magnified image between 30 and 50 centimeters, allowing the user to maintain an appropriate viewing distance when using the present invention.

DETAILED DESCRIPTION

[0034] See Figures 1 to 3 An embodiment of the high-definition zoom lens 100 provided by the present invention is a desktop device suitable for being placed on a table 91 or clamped on the edge of the table 91 and used to obtain a magnified image 93 of an object 92 at a far side (see Figure 5 ) and is viewed by a user 94. In this embodiment, the distal side is defined as a position away from the user 94 and the object 92. The high-definition zoom telescope 100 comprises a bracket unit 2, a base unit 3, and a light source unit 4. During use, the high-definition zoom telescope 100 is placed in front of the user's 94 line of sight.

[0035] The bracket unit 2 is suitable for placement on the desktop 91 or clamping onto the edge of the desktop 91. The bracket unit 2 of this embodiment includes a base 21 placed on the desktop 91, and a support rod 22 extending upward from the base 21 along a vertical direction Z. The base 21 extends along a front-to-back direction X perpendicular to the vertical direction Z. The support rod 22 has a lower end 221 fixed to the base 21 and an upper end 222 opposite the lower end 221. In this embodiment, the upper surface of the upper end 222 is an inclined surface.

[0036] The lens base unit 3 is disposed above the support rod 22 of the bracket unit 2 in the vertical direction Z and is used to construct an optical path P for obtaining the magnified image 93 at the distal end. In some embodiments, the support rod 22 can be configured as a liftable rod to adjust the height of the lens base unit 3. The lens base unit 3 includes an eyepiece base 31, a rotating shaft 32, and an objective lens base 33.

[0037] The eyepiece mount 31 is disposed at the upper end 222 of the support rod 22 in the vertical direction Z and includes a lower housing 311 disposed at the upper end 222 and a reflective lens 312 that is higher than the tabletop 91 and fixed to the lower housing 311 and faces the user 94. The lower housing 311 has a lower edge 313 adjacent to the base 21. The reflective lens 312 is tilted from top to bottom and toward the user 94. The reflective lens 312 is referred to as the distal end.

[0038] See Figure 3 and Figure 4 The reflective lens 312 is tilted at an angle A1 relative to the desktop 91. When the angle A1 is between 30 and 80 degrees, the center of the reflective lens 312 can be approximately aligned with the line of sight of the user 94. The user 94 can look straight at the reflective lens 312 without looking up or down, which is more ergonomic. The reflective lens 312 of this embodiment is a concave mirror with a free-form surface, which has the function of magnifying the image. However, in other embodiments, the reflective lens 312 can also be a spherical concave mirror, or it is not necessary to magnify the image, so the reflective lens 312 can also be a plane mirror. In addition, the reflective lens 312 of this embodiment is a trapezoid that is wide at the top and narrow at the bottom, which can avoid the problem of glare caused by the user 94 looking at the ceiling through the reflective lens 312, but the present invention is not limited to this.

[0039] See Figures 1 to 3 The rotating shaft 32 is arranged at the top end of the eyepiece lens holder 31, and the rotating shaft 32 extends along a horizontal direction Y (i.e., left-right direction) perpendicular to the up-down direction Z and the front-back direction X.

[0040] One end of the objective lens mount 33 is disposed on the rotating shaft 32 and can be flipped relative to the eyepiece mount 31. The objective lens mount 33 has an upper shell 331 connected to the rotating shaft 32, and a magnifying lens 332 fixed to the upper shell 331 and used to magnify an image. The upper shell 331 has a side edge 333 away from the rotating shaft 32. The magnifying lens 332 is located above the object 92 in the vertical direction Z. The magnifying lens 332 in this embodiment is a free-form concave mirror, and its area is larger than that of the reflective lens 312. However, in other embodiments, the magnifying lens 332 can also be a concave mirror of other forms, which also has the function of magnifying an image.

[0041] See Figure 4 and Figure 5 The optical path P of the present invention is reflected from the object 92 to the magnifying lens 332, then reflected from the magnifying lens 332 to the reflective lens 312, and then reflected from the reflective lens 312 to produce the magnified image 93. Therefore, the user 94 can clearly see the magnified image 93 by looking directly at the reflective lens 312 (i.e., the far side) while maintaining an appropriate viewing distance.

[0042] In this embodiment, the magnifying lens 332 has a warping effect that causes the image to bend downward, and the reflecting lens 312 has a warping effect that causes the image to bend upward. Therefore, the two free-curvature concave mirrors, the magnifying lens 332 and the reflecting lens 312, can offset each other's deformation of the imaging warping to obtain the magnified image 93 with the same proportions as the object 92 and without warping.

[0043] The reflecting lens 312 and the magnifying lens 332 form an angle A2. In this embodiment, the angle A2 is 49 degrees. However, a better imaging effect can be achieved if the angle A2 is between 40 and 60 degrees.

[0044] In addition, a side edge 334 of the magnifying lens 332 is separated from the upper surface of the object 92 by a distance d in the vertical direction Z. In the present embodiment, the distance d is 50 cm. If the distance d is too large, the image will be out of focus. If the distance d is too small, the user 94's line of sight will be blocked. Therefore, the distance d is more suitable to be between 40 and 60 cm.

[0045] Based on the numerical ranges of angle A2 and distance d, the free-form surface parameters of the reflective lens 312 and the magnifying lens 332 can be calculated. When the object 92 passes through the optical path P, its image is magnified and presented on the reflective lens 312 (i.e., the far side), allowing the user 94 to easily read the contents of the object 92 while maintaining a suitable viewing distance between 30 cm and 50 cm. If the user 94 is too close to the present invention, the magnified image 93 will be over-magnified, making it difficult for the user 94 to see. If the user 94 is too far away from the present invention, the magnified image 93 will be under-magnified, making it difficult to see clearly. Therefore, the user 94 can maintain a suitable viewing distance while using the present invention, while still enjoying a better viewing angle and comfortable reading.

[0046] See Figure 1 、 Figure 2 and Figure 6 The rotating shaft 32 comprises a first pivot portion 321 formed on one side of the lower housing 311, a second pivot portion 322 formed on one side of the upper housing 331 and rotatable relative to the first pivot portion 321, and a knob 323. Specifically, the second pivot portion 322 is composed of two pivot pieces spaced apart in the transverse direction Y. The rotating shaft 32 also has two caps 324 fixed to the outer sides of the two pivot pieces. By turning the knob 323, the angle A2 can be adjusted and fixed.

[0047] See Figure 1 and Figure 7 The objective lens holder 33 can be in an open state (such as Figure 1 ) and a closed state (such as Figure 7 ) pivot.

[0048] See Figure 1 and Figure 2 When the objective lens mount 33 is in the open state, the objective lens mount 33 is opened to a slightly horizontal state, and the side edge 333 of the objective lens mount 33 is slightly lower than the rotating shaft 32 and higher than the lower edge 313 of the eyepiece mount 31.

[0049] See Figure 7 and Figure 8 When the objective lens holder 33 is in the covering state, the objective lens holder 33 covers the eyepiece holder 31, and the side edge 333 of the objective lens holder 33 is lower than the lower edge 313 of the eyepiece holder 31. Figure 8 It can be seen that the length of the objective lens mount 33 is greater than the length of the eyepiece lens mount 31 .

[0050] See Figure 2 、 Figure 4 and Figure 6 The light source unit 4 is used to provide light along the optical path P. In this embodiment, the light source unit 4 is an LED lamp and is disposed on the lower edge 313 of the lower housing 311. However, in other embodiments, the light source unit 4 can also be a light source installed in other locations, or replaced by an existing household lamp, as long as it can provide sufficient light for the mirror base unit 3.

[0051] See Figure 9 Furthermore, the lens holder unit 3 of this embodiment further includes a photographing unit 34. The photographing unit 34 is mounted on the shaft 32 and has a lens mounted inside the shaft 32 and capable of facing the user 94 (see FIG. Figure 4 ) is captured by the lens 341. This provides a monitoring or recording effect, allowing the user 94 to understand their status during use. In some embodiments, the position of the camera unit 34 can be changed or omitted.

[0052] See Figure 6 The eyepiece mount 31 of this embodiment further includes two sockets 314 formed on the back of the lower housing 311. These two sockets 314 are used to connect external power cables to provide power to the photographic unit 34 and the light source unit 4. In other embodiments, the high-definition zoom lens 100 of the present invention may also be powered by a built-in battery.

[0053] See Figure 10 , is a variation of this embodiment. The differences are:

[0054] The support rod 22 of the bracket unit 2 is plate-shaped and extends upward from the edge of the base 21 and toward the user 94 (see FIG. Figure 4 The upper end 222 of the support rod 22 extends obliquely in a direction away from the user 94.

[0055] A counterweight (not shown) is disposed inside the base 21 to maintain the center of gravity.

[0056] The eyepiece base 31 further has a sliding groove 315 formed on the back side of the lower shell 311 .

[0057] The upper end 222 of the support rod 22 is slidably mounted on the eyepiece base 31. The support rod 22 has an adjustment member 223 that is rotatably locked to the upper end 222 and the slide slot 315. By loosening the adjustment member 223, the base unit 3 can be moved up and down relative to the bracket unit 2 in the vertical direction Z to change the height of the base unit 3. The adjustment member 223 can be a knob or other element that can be tightened and loosened.

[0058] The high-definition zoom lens 100 provided by the present invention can be placed directly on the tabletop 91, or the base 21 can be designed as a clip-type device that can be clamped to the edge of the tabletop 91 for use. The user 94 simply opens the objective lens mount 33 to its open position, places the object 92 below the objective lens mount 33, and maintains a horizontal line of sight toward the eyepiece mount 31 to see the magnified image 93 on the reflective lens 312 (i.e., the far side). The user 94 can maintain an appropriate viewing distance of 30 to 50 centimeters while using the present invention, while still enjoying an optimal viewing angle and reading comfort. Furthermore, the horizontal position of the objective lens mount 33 prevents the user 94 from getting too close to the present invention, thereby maintaining an appropriate viewing distance and effectively achieving the objectives of the present invention.

[0059] The above description is only a preferred embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
