It should be noted that the related numbers and shapes mentioned in the embodiment corresponding to the drawings are only used for specifically describing the embodiments of the present invention, so as to facilitate understanding of the contents of the present invention, and are not used for limiting the protection scope of the present invention.

[ example one ]

Referring to fig. 1 to 5 and 7 to 14, a first embodiment of the present invention discloses a device 100 capable of multi-lens transposition, which includes a view display device 1, a connection module 2 for mounting the view display device 1 on an electronic device 800 (e.g., a mobile phone or a tablet), a light supplement and polarization control module 3 located in the view display device 1 for providing light supplement and eliminating unnecessary reflected light, a light shield 4 for shielding external light interference, and a charging module 5 for supplying power to the view display device 1 and the light supplement and polarization control module 3.

In the first embodiment, the visual display device 1 having at least two lenses 131 is collocated with the corresponding modules and elements for explanation, but the present invention is not limited to the structural design of the connection module 2, the light supplement and polarization control module 3, the light-shielding cover 4, and the charging module 5, and the connection relationship with the electronic device 800 (e.g., mobile phone, tablet, etc.) or the object 900 to be magnified (e.g., article, book, newspaper, etc.). That is, in the embodiment of the present invention, the visual display device 1 can be applied alone or used in combination with other modules or elements.

As shown in fig. 1 to 8, the visual display device 1 includes a housing 11 and a lens module 13 disposed in the housing 11. The following describes the positional relationship between the elements of the visual display device 1.

As shown in fig. 2 and fig. 3 in conjunction with fig. 1, the lens module 13 of the first embodiment includes at least two lenses 131, and in the embodiment of the present invention, two lenses with the same magnification are used for illustration, so the following structure is only an embodiment of the present invention but the present invention is not limited thereto. The housing 11 includes an upper shell 111, a lower shell 112 detachably assembled with the upper shell 111, and at least one window 113 penetrating the upper shell 111 and the lower shell 112. In the embodiment of the present invention, the window 113 of the housing 11 is illustrated as two, that is, a first window 113 and a second window 113' are formed on the upper shell 111 and the lower shell 112, and a track 115 is recessed on each of two opposite sides of the housing 11, the track 115 extends along the side edge of the housing 11 in a substantially horizontal line. The lens module 13 includes two lenses 131 with the same magnification, which are fixed in the housing 11 and respectively correspond to the first window 113 and the second window 113' (or respectively correspond to the second window 113 and the first window 113). Moreover, the structural design of the above-mentioned visual display device 1 and its matching connection module 2, light supplement and polarization regulation module 3, light shield 4, and charging module 5 is similar to the following structural configuration and description, and therefore, the detailed description thereof is omitted.

Thus, when the connection module 2 mounts the visual display device 1 on the electronic device 800, the connection module 2 can provide a fine adjustment alignment of a horizontal position, a vertical position or an inclination angle for the visual display device 1 relative to the image capturing lens 801 by using any lens 131 relative to the window 113 (or 113') and relative to the position of the image capturing lens 801 to magnify the image of the image capturing lens 801, that is, for the actual position of the image capturing lens 801 on the electronic device 800. The light supplement and polarization control module 3 is mounted on the housing 11 and can provide light source and fine-tuning illumination for the lens module 13.

It should be noted that, in the first embodiment, the lens module 13 may also include two lenses with different magnifications as an embodiment for illustration, so that the visual display device 1 further includes a visual control module 12 located in the housing 11 and used for cooperating with the above-mentioned corresponding modules and elements to make a structural design and a configuration relationship as described below.

Referring to fig. 4 and 5 in conjunction with fig. 1, in the embodiment of the present disclosure, the window 113 of the housing 11 formed by the upper shell 111 and the lower shell 112 includes a first window 113 and a second window 113', and a notch 114 is formed at a corner of one side of the housing 11, and a track 115 is recessed at two opposite sides of the housing 11. The view control module 12 includes a wheel 121 rotatably disposed on the inner surface of the lower shell 112, and the wheel 121 has a side edge with insections 1211. However, the present invention is not limited to other linkage structures of the view control module 12.

As shown in fig. 5, the lens module 13 and the view control module 12 are linked in a linkage structure, so the following structure is only for illustration and the present invention is not limited thereto. The lens module 13 includes a lens holder 132, at least two lenses 131 with different magnifications, and a display magnification adjustment interface 133. The lens holder 132 is axially disposed on the inner surface of the lower housing 112 with a central axis C as the center, and the side edge of the lens holder 132 is provided with insections 1322 corresponding to the insections 1211 of the roller 121, so that the lens holder 132 can be driven by the roller 121 and can rotate relatively in the housing 11 through the central axis C. At least two assembling holes 1321 are formed on the lens holder 132 corresponding to the two windows 113, 113' of the housing 11.

The at least two lenses 131 with different magnifications include a first lens 1311 and a second lens 1312, which can be respectively fixed on the assembly holes 1321, such that the optical axis of the first lens 1311 (or the second lens 1312) is substantially perpendicular to the horizontal shell surface of the housing 11, and when the lens mount 132 is rotated, the first lens 1311 and the second lens 1312 can be switched to correspond to the first window 113 and the second window 113 '(or respectively correspond to the second window 113' and the first window 113).

The display magnification adjustment interface 133 can mark a scale 1331 on the upper surface of the first lens 1311 (or the second lens 1312) in a predetermined proportional relationship according to different magnification parameters of the first lens 1311 (or the second lens 1312) to correspond to and display the magnification of the enlarged (or wide-angle) image in the first lens 1311 (or the second lens 1312).

In the first lens 1311 and the second lens 1312 according to this embodiment, each lens element may be formed by a parallax barrier or a lens. The lens is described below in this embodiment. As shown in fig. 11, the lens can be selected from a group consisting of a single biconvex lens L1, a single plano-convex lens L2, a meniscus lens L3, a single plano-concave lens L4, a single biconcave lens L5, a biconvex achromatic lens L6, and a plano-convex achromatic lens L7, and can be arranged and combined differently according to different practical functions. For example, a lens assembly including a single plano-concave lens L4, a single biconcave lens L5, and a meniscus lens L3 can achieve a high-quality wide-angle photographing function. If the lens consists of a single biconvex lens L1, a single plano-convex lens L2, a biconvex achromatic lens L6 and a plano-convex achromatic lens L7, the microscopic magnification shooting function can be achieved.

Thus, the wheel 121 of the view control module 12 is used to drive the lens mount 132 of the view display device 1 to synchronously rotate, so that the lens mount 132 can be switched to one mode in which the first lens 1311 and the second lens 1312 respectively correspond to the first window 113 and the second window 113 '(or another mode in which the first lens 1311 and the second lens 1312 respectively correspond to the second window 113' and the first window 113), and an optical axis of any magnification lens 1311 (or 1312) in any mode is substantially perpendicular to an image capturing lens 801 of the electronic device 800, so as to change the field of view and the image magnification (or wide-angle) shooting effect function of switching/focusing lenses with different magnification.

As shown in fig. 4, 5, 6, 8 and 14, the connection module 2 is used to connect to one side of the housing 11, and includes an L-shaped clip body 21 made of metal material or plastic steel material, and one end of the L-shaped clip body is connected to one end of the lower shell 112 of the housing 11, and the other end of the L-shaped clip body 21 is substantially perpendicular to the one end and extends to form a clip sheet 211, and is parallel to the lower shell 112 and opposite to the windows 113, so that the clip sheet 211 of the clip body has elasticity. The clip sheet 211 of the clip body 21 has a viewing window 212, and the viewing window 212 is used to directly correspond to and view the light image enlarged (or wide-angle) by the lens 131 in the window 113 of the housing 11.

Further, in this embodiment, a protection protrusion 213 is protruded from the inner surface of the clip 211. Thus, when the device 100 is clipped in front of the image capturing lens 801 of the electronic device 800 by the clip 211 of the clip 21, that is, the view display device 1 can provide any position (e.g., a horizontal position, a vertical position) and a fine adjustment alignment of an inclination angle (see, for example, fig. 9, 10, 11, 12) relative to the image capturing lens 801 by the clip 21, and the protection protrusion 213 abuts against a liquid crystal panel 802 of the electronic device 800, so that the clip 211 can be prevented from directly contacting the liquid crystal panel 802, thereby avoiding the risk of scratching (see, for example, fig. 15).

More specifically, as shown in fig. 3, two springs 214 may be added to the L-shaped clip body 21 of the connection module 2 for connecting to the lower shell 112 of the housing 11, so that the clip body 21 has better opening and resilient restoring elastic effects. When the clip piece 211 of the clip body 21 is used for clipping the electronic device 800, the springs 214 can increase the pulling-open and return elasticity of the clip body 21, so that the housing 11 can be smoothly clipped on the electronic device 800 (as shown in fig. 15), and can be smoothly removed. Similarly, the springs 214 can also be disposed in the structure of the L-shaped interposer 21 of the connection module 2 shown in fig. 5 and 6.

As shown in fig. 1 and 5, the light supplement and polarization control module 3 is installed in the housing 11 and controls the lens module 13 to provide light supplement and polarization functions. The light supplement and polarization control module 3 includes at least two sets of LED illuminators 31 for providing sufficient light source for each lens 131, at least two sets of polarizers (not shown) for converting light beams generated by the LED illuminators 31 into polarized light, and a control module 33 for electrically controlling the LED illuminators 31 and the polarizers. In the present embodiment, the at least two groups of LED illuminators 31 and the at least two groups of polarizer assemblies correspond to the two lenses 131 (including the first lens 1311 and the second lens 1312) of the lens module 13, which are illustrated as two groups. The connection relationship between the light supplement and the elements of the polarization control module 3 will be described below.

The two groups of LED illuminators 31 may be located at predetermined holes of the upper shell 111 of the housing 11 and respectively correspond to the positions of the first lens 1311 and the second lens 1312 of the lens module 13, and each group of LED illuminators 31 includes two LED lamps (not shown in the drawings), and the two LED lamps are respectively located at two opposite sides of the upper shell 111 corresponding to the first lens 1311 (or the second lens 1312), so as to provide a proper light source for the first lens 1311 (or the second lens 1312) in a balanced manner. The two polarizer sets (not shown) are respectively adjacent to the two LED illuminators 31, and each polarizer set includes two polarizers (not shown), and the two polarizers respectively correspond to two LED lamps (shown in fig. 1, 5, and 6) adjacent to each LED illuminator 31. The control module 33 is disposed in the housing 11 and includes a control circuit 331 electrically connected to the LED illuminators 31 and the polarizer sets, the control circuit 331 is electrically connected to the lens module 13 of the viewing display device 1, and a touch switch 332 (shown in fig. 1) electrically connected to the control circuit 331.

Further, when the lens module 13 is switched to enable the first lens 1311 (or the second lens 1312) with any magnification, the touch switch 332 can turn on two LED lamps and two polarizers corresponding to the first lens 1311 (or the second lens 1312), provide sufficient light sources and convert light beams generated by the light sources of the LED lamps into polarized light, so as to eliminate unnecessary reflected light generated by the LED lamps, thereby preventing the first lens 1311 (or the second lens 1312) from causing an edge reduction effect of an image due to a magnifying (or wide-angle) effect of the lens magnification, and having an anti-dazzling effect, so that the magnified (or wide-angle) image is clearer. Moreover, the user can adjust the brightness of the LED light sources by pressing the touch switch 332, and the first lens 1311 (or the second lens 1312) can be used for providing fine tuning illumination of the light sources and polarized light, so as to better meet the actual use effect of the user.

More specifically, the touch switch 332 in this embodiment can be a touch key disposed on the housing 11, which allows a user to turn on the touch key in a predetermined manner and to perform a required fine-tuning illumination operation, but the present invention is not limited thereto.

As shown in fig. 1 to 7, the light-shielding case 4 is surrounded by the case wall to form a hollow case, which includes a viewing window 41 penetrating the hollow case and sliding portions 42 protruding outwards from two opposite sides of the bottom of the light-shielding case 4. Wherein, the surrounding wall of the light-shielding cover 4 is a substantially trapezoidal body with a top aperture smaller than a bottom aperture, the window aperture 41 is a through hole passing through the top and bottom, and the sliding portion 42 extends from the free end edge to the inner surface and has a hook 421. Thus, the light shielding cover 4 can be covered on the upper shell 111 of the housing 11 at the bottom approximately horizontally, and the hook 421 of the sliding portion 42 is fastened on the rail 115 of the side edge of the housing 11, so that the light shielding cover 4 can slide on the upper shell 111 relatively horizontally, and the window hole 41 of the light shielding cover 4 can achieve a complete covering effect (as shown in fig. 7) relative to the first window 113 (or the second window 113 ') of the upper shell 111, thereby providing a function of effectively preventing an external light source from interfering with the light image displayed by the first lens 1311 (or the second lens 1312) in the first window 113 (or the second window 113'). And the light-shielding cover body 4 and the connection module 2 are respectively located on different sides of the housing 11 (i.e., respectively located outside the upper case 111 and the lower case 112).
