Description

[0001] This application claims priority to a Taiwan patent filed on April 2, 2025, application number 114203339, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to an optical magnification device, and more particularly to a high-resolution zoom lens with a headrest. Background Technology

[0003] The forced anti-myopia reading zoom lens disclosed in Chinese Utility Model Patent Publication No. CN218099783U includes an adjustment mechanism standing upright on the ground, an eyepiece mounted on the top side of the adjustment mechanism and located above the desk, and an objective lens spaced opposite to the eyepiece. The adjustment mechanism has a support arm, a mounting bracket pivotally connected to the upper end of the support arm for mounting the eyepiece, and two connecting shafts pivotally mounted at opposite ends of the mounting bracket for mounting the objective lens. The objective lens and the eyepiece are rotatably connected to each other via the connecting shafts. When a user places a book on the desk, the contents of the book are reflected into the user's eyes through the optical reflection principle of the objective lens and the eyepiece.

[0004] Although using the aforementioned telescope to read can increase the reading distance, the mounting bracket is easily affected by environmental vibrations, causing the eyepiece and objective lens to shake, thus affecting the reading experience. Utility Model Content

[0025] Before this utility model is described in detail, it should be noted that in the following description, the terms such as up, down, left, right, front, and back are not absolute positions and can be interchanged as appropriate.

[0026] See Figures 1 to 3 This utility model provides an embodiment of a high-powered telephoto lens with a headrest, suitable for reflecting a magnified image of an object 91 to the eye of a user 92. The high-powered telephoto lens with a headrest includes a support unit 100 and a lens assembly unit 300.

[0027] The support unit 100 includes a base 11, a plurality of suction cups 12 disposed on the bottom side of the base 11 along a vertical direction Z, an arm assembly 13 disposed on the base 11, and a movable seat 2 rotatably positioned at the top of the arm assembly 13. The suction cups 12 are used to adhere to and fix the base 11 to a tabletop, increasing its stability. In some embodiments, the suction cups 12 can be omitted; stability can be maintained simply by increasing the weight or size of the base 11. The arm assembly 13 is disposed on the top side of the base 11 along the vertical direction Z. In this embodiment, the arm assembly 13 has two pivotally connected movable arms 131. The movable arms 131 are used to move the lens assembly unit 300 along the vertical direction Z, a left-right direction X, and a front-back direction Y, which are perpendicular to each other. Since the movable arms 131 are existing components and have various variations, those skilled in the art can deduce further details from the above description, and therefore will not be elaborated further.

[0028] See Figure 1 , Figure 5 and Figure 6 The movable seat 2 has a universal joint 21 rotatably connected to the arm assembly 13, and a seat body 22 rotatably pivotally mounted on the universal joint 21. The universal joint 21 is used to drive the seat body 22 to rotate relative to the support unit 100 in three-dimensional space. The seat body 22 is U-shaped and has two sliding grooves 220 spaced apart in the left-right direction X.

[0029] The lens assembly unit 300 is detachably mounted on the movable base 2 and supported by the arm assembly 13. The lens assembly unit 300 includes a mounting base 4 detachably mounted on the movable base 2, an objective lens assembly 5 disposed on the mounting base 4, and an eyepiece assembly 7 disposed on the mounting base 4.

[0030] The mounting base 4 has two mounting arms 41 that slide into the groove 220, a fixed arm 42 connected to the front side of the mounting arms 41, and a connecting arm 43 connected to the rear side of the mounting arms 41. In some embodiments, the mounting base 4 is a one-piece molded part. The connecting arm 43 has two upright sections 431 that extend upward from the mounting arms 41, and a headrest 432 connected to the top side of the upright sections 431. In some embodiments, the headrest 432 is arc-shaped.

[0031] In this embodiment, the mounting arm 41 and the slide groove 220 are engaged with each other in a form-fitting manner. Therefore, the mounting seat 4 is limited in both the vertical direction Z and the horizontal direction X. In addition, a magnet is installed in each mounting arm 41, and a magnet is also installed on the movable seat 2 near the slide groove 220, so that the mounting seat 4 magnetically attracts the movable seat 2. Therefore, the mounting seat 4 is also limited in the front-back direction Y and will not slide out of the slide groove 220.

[0032] See Figures 5 to 7 The objective lens group 5 is disposed on the mounting base 4 and is lower than the headrest portion 432 in the vertical direction Z. In some embodiments, the objective lens group 5 is rotatably pivotally mounted at the junction of the upright section 431 of the mounting arm 41 and the connecting arm 43, thereby allowing the angle of the objective lens group 5 to be adjusted. The objective lens group 5 has a first lens mount 51 and an objective lens 52 fixed to the first lens mount 51. In this embodiment, the objective lens 52 is a convex mirror.

[0033] The eyepiece assembly 7 is used for viewing by the user 92 and is spaced apart from the objective lens assembly 5 in the front-rear direction Y on the mounting base 4. Specifically, the eyepiece assembly 7 is located in front of the headrest 432 in the front-rear direction Y and lower than the headrest 432 in the vertical direction Z. The eyepiece assembly 7 is located in front of the objective lens assembly 5, that is, the objective lens assembly 5 is located behind the eyepiece assembly 7. The eyepiece assembly 7 has a second lens mount 71 and an eyepiece 72 fixed to the second lens mount 71. In this embodiment, the eyepiece 72 is a concave mirror.

[0034] See Figure 1 and Figure 3In use, the user 92 places their forehead near the headrest 432 and their eyes aligned with the eyepiece 72. The image of the object 91 is magnified by the objective lens 52 and reflected to the eyepiece 72, allowing the user 92 to see a magnified virtual image of the object 91 at a distance through the eyepiece 72. Through the optical reflection between the objective lens 52 and the eyepiece 72, the imaging distance of the object 91 is increased and the image magnified, thereby increasing the viewing distance and avoiding excessive strain on the eyes. Simultaneously, the headrest 432 of the mounting base 4 allows the user 92's forehead to be close to or rest against it, preventing the lens assembly unit 300 from shaking due to environmental vibrations, and allowing the user 92 to obtain the maximum field of view through the eyepiece 72, ensuring clear imaging and optimal viewing effect. Therefore, the purpose of this utility model is indeed achieved.

[0035] See Figure 8 To enhance comfort, in some embodiments, the mounting base 4 further includes a flexible pad 44 fixed inside the headrest portion 432 of the connecting arm 43. The flexible pad 44 may be, for example but not limited to, foam, silicone sheet, cooling pad, or latex. The soft touch and / or cooling sensation of the flexible pad 44 enhances comfort when the user's forehead rests against it, allowing for prolonged use.

[0036] The above description is merely an embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
