Description

Technical Field

[0001] The utility model relates to the technical field of vision correction, in particular to a multifunctional telescope. Background Art

[0002] Telescopes move the image of an object that was originally close to the target farther away, thereby achieving the purpose of reducing close-up vision. The principle of telescopes is to turn close vision into far vision, for example, to zoom out from a close distance of 20-30 cm to more than 5 meters, so that the eye's adjustment ability is not used and there is no pressure on the eye when using close distance.

[0003] However, the existing telescope can only manually move the objective lens toward the eyepiece horizontally closer or farther. For taller or shorter children, the telescope needs to be raised or lowered a certain distance. However, in this case, the image reflected by the eyepiece may not be clear, which may further aggravate the child's myopia.

[0004] For example, utility model patent CN220650971U proposes "a non-continuously adjustable telescope", which is provided with a support platform, and a plurality of equally spaced adjustment positions are arranged front to back; a rotating shaft is provided at both ends of the objective lens, and a mounting seat is rotatably provided on the rotating shaft. When assembled in place, the mounting seat is located at the adjustment position, and the objective lens can be adjusted once through the plurality of adjustment positions to reach the position the user wants to adjust. However, it can only realize manual movement of the objective lens in the horizontal direction. When manually adjusting, the distance between the eyepiece and the objective lens cannot be accurately adjusted. Moreover, when moving in the horizontal direction, due to the change in the distance between the eyepiece and the objective lens, the image of the objective lens reflected by the eyepiece may also be unclear, thereby further aggravating the child's myopia.

[0005] Therefore, there is an urgent need for a telescope that can make the image reflected by the eyepiece of the telescope clearer. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] Embodiment 1

[0035] like Figure 1-Figure 8 As shown, a multifunctional telescope of the present embodiment includes a mounting plate 1, two side plates 2 connected to the two ends of the mounting plate 1, an eyepiece 3 mounted on the inner wall of the mounting plate 1, an objective lens 4 arranged opposite to the eyepiece 3 and with a certain interval therebetween, and a transverse movement device 5 and a lifting device 6 arranged on the inner walls opposite to the side plates 2.

[0036] Specifically, the two ends of the objective lens 4 are connected to the side plate 2 through a transverse moving device 5 and a lifting device 6; the lifting device 6 is connected to the side wall on the opposite side of the transverse moving device 5 through a guide rail, and two lifting devices 6 are provided, and the two ends of the objective lens 4 are rotatably connected to the side walls on the opposite side of the two lifting devices 6 respectively; the transverse moving device 5 can drive the lifting device 6 and the eyepiece 3 to move laterally in the direction of approaching or moving away from the eyepiece 3, and the lifting device 6 can drive the objective lens 4 to move vertically to change the vertical distance between the objective lens 4 and the reading and writing platform. By installing two transverse moving devices 5 and two lifting devices 6 on the two side plates 2, the transverse moving device 5 can drive the objective lens 4 to move laterally to change the distance between the eyepiece 3 and the objective lens 4, thereby changing the change of the image distance of the eyepiece 3, thereby changing the distance of the reflected image, and then achieving the change of the distance and size of the child's view of different images. The two lifting devices 6 can realize the lifting and lowering of the objective lens 4 on the basis of the two transverse movement devices 5, so as to change the distance between the objective lens 4 and the reading and writing platform. It can not only change the clarity of the image presented by the objective lens 4 and reflected on the eyepiece 3, but also change the image distance of the eyepiece 3, so as to make the reader more suitable for children of different heights or ages, and avoid further aggravation of children's myopia.

[0037] Furthermore, the transverse movement device 5 includes a first motor 51, a first threaded rod 52, a first moving block 53 and a first fixing member 54; the first motor 51 is fixedly installed on the inner wall of the side plate 2, the first threaded rod 52 is fixedly connected to the output end of the first motor 51, the first moving block 53 is sleeved on the outer wall of the first threaded rod 52, the first fixing member 54 is fixedly installed on the side wall of the side plate 2 and the end of the first threaded rod 52 away from the first motor 51 passes through the first fixing member 54; the guide rail is arranged on the side of the first moving block 53 away from the side plate 2; the first motor 51 can drive the first threaded rod 52 to rotate, so as to drive the first moving block 53 and the lifting device 6 to move along the axis of the first threaded rod 52, so as to realize automatic adjustment of the horizontal distance between the objective lens 4 and the eyepiece 3, so that when adjusting the horizontal distance between the objective lens 4 and the eyepiece 3, it can be more accurate, and macro adjustment can also be realized, so that the distance between the eyepiece 3 and the objective lens 4 can be adjusted more accurately and more stably. It is explained here that a screw nut structure is formed between the first threaded rod 52 and the first movable block 53. Since both ends of the objective lens 4 are rotatably connected to the lifting device 6, the objective lens 4 can resist the first movable block 53, so that the first movable block 53 cannot rotate with the rotation of the first threaded rod 52. Therefore, since the first movable block 53 is rotatably connected to the first threaded rod 52 by thread, when the first threaded rod 52 rotates, the first movable block 53 moves along the axis of the first threaded rod 52, thereby changing the horizontal distance between the objective lens 4 and the eyepiece 3.

[0038] Furthermore, the transverse movement device 5 also includes two first limit switches 55; the first fixing member 54 is L-shaped and the L-shaped opening faces the first motor 51, and one first limit switch 55 is fixedly installed on the top wall of the horizontal section of the first fixing member 54 and is located below the first threaded rod 52; the other first limit switch 55 is fixedly installed above the first motor 51 through a mounting frame, and the two first limit switches 55 are both set toward the first moving block 53. By setting limit switches, and a first limit switch 55 is installed on the top wall of the horizontal section of the first fixing member 54, and the other is installed above the first motor 51, when the first moving block 53 moves horizontally along the axis of the first threaded rod 52, the two first limit switches 55 can limit the moving distance of the first moving block 53, that is, when the side wall of the first moving block 53 close to the first motor 51 moves, it contacts with a first limit switch 55, and the first limit switch 55 immediately transmits an electrical signal to the first motor 51 and drives the first motor 51 to turn off, thereby preventing the first moving block 53 from moving to the end point of the first threaded rod 52, and the first motor 51 continues to drive the first threaded rod 52 to rotate, so that the first moving block 53 always moves on the first threaded rod 52, once the first moving block 53 is located at the end point of the first threaded rod 52, since the first motor 51 is not turned off, the first moving block 53 continues to move, thereby causing the first moving block 53 to be damaged; the other first limit switch 55 has the same function as it, which will not be repeated here.

[0039] Furthermore, the transverse movement device 5 also includes a first U-shaped optical coupler 56; the first U-shaped optical coupler 56 is fixedly installed on the inner wall of the side plate 2 through a connecting piece and the opening of the U-shaped optical coupler faces the objective lens 4; a first fixing ring 57 is fixedly installed at one end of the first threaded rod 52 away from the first motor 51, the first fixing ring 57 is fixedly installed at the end of the first threaded rod 52 away from the first motor 51 and there is a gap between the first fixing ring 57 and the first fixing piece 54, the first fixing ring 57 can rotate with the rotation of the first threaded rod 52, the first fixing ring 57 includes a first annular cylinder and a first straight plate, one side wall of the first straight plate is connected to one end of the first annular cylinder, one end of the first straight plate is located in the opening of the U-shaped optical coupler, and is used to measure the moving distance of the first moving block 53. The U-shaped optical coupler uses an infrared LED (wavelength of 940nm) to transmit light, and then receives the radiation light generated by the reflected light (irradiating the infrared light on the surface of the object to be measured and reflecting it back) through an optical coupler isolator, and then converts it into an electrical signal. The intensity of the electrical signal output by the receiver is inversely proportional to the distance, thereby achieving the purpose of measuring the distance. Therefore, by setting the first U-shaped optical coupler 56, it is possible to measure the distance that the first moving block 53 moves along the axis of the first threaded rod 52, thereby realizing the measurement of the moving distance of the objective lens 4, so as to accurately adjust the moving distance of the first moving block 53.

[0040] Furthermore, the lifting device 6 includes a second motor 61 , a second threaded rod 62 , a second moving block 63 , a second fixing member 64 and a track assembly 65 .

[0041] Specifically, the track assembly 65 is installed on the inner wall of the side panel 2, and the second motor 61 and the second fixing member 64 are movably connected to the track assembly 65, so that when the first moving block 53 moves, the second motor 61 and the second fixing member 64 can move along with the movement of the first moving block 53 through the track assembly 65, so that the lifting device 6 can move vertically on the basis of horizontal movement. The side of the second moving block 63 close to the first moving block 53 is movably connected to the first moving block 53 through a guide rail, and the guide rail is perpendicular to the moving direction of the first moving block 53, so that when the second moving block 63 moves vertically, the guide rail can limit the second moving block 63, and through the guide rail, the first moving block 53 and the second moving block 63 can also be indirectly movably connected, so that the transverse movement device 5 and the lifting device 6 form an integral device, that is, they can be lifted and lowered during the transverse movement, or moved transversely during the lifting process, so that the image of the objective lens 4 reflected by the eyepiece 3 is clearer; the second threaded rod 62 is connected to the output end of the second motor 61 and the second threaded rod 62 is perpendicular to the first threaded rod 52, the second moving block 63 is sleeved on the second threaded rod 62, and the second fixing member 64 is fixedly installed on the inner wall of the side plate 2 through the track assembly 65 and the end of the second threaded rod 62 away from the second motor 61 passes through the second fixing member 64. By driving the second motor 61, the second threaded rod 62 can be driven to rotate, and then the second moving block 63 can be driven to vertically lift along the axis of the second threaded rod 62, and then the objective lens 4 can be vertically lifted, so as to limit the second moving block 63 and achieve the purpose of lifting the objective lens 4. It should be explained here that a lead screw nut structure is formed between the second threaded rod 62 and the second moving block 63. Since the two ends of the objective lens 4 are rotatably connected to the second moving block 63, the objective lens 4 can resist the second moving block 63, so that the second moving block 63 cannot rotate with the rotation of the second threaded rod 62. Therefore, since the second moving block 63 is rotatably connected to the second threaded rod 62, when the second threaded rod 62 rotates, the second moving block 63 moves along the axis of the second threaded rod 62, so as to change the vertical distance between the objective lens 4 and the reading and writing platform.

[0042] Furthermore, the lifting device 6 also includes two second limit switches 66; one second limit switch 66 is connected to the side wall of the second motor 61; the second fixing member 64 is L-shaped and the L-shaped opening faces the eyepiece 3, and the other second limit switch 66 is installed on the top wall of the horizontal section of the second fixing member 64 and is located between the second threaded rod 62 and the vertical section of the second fixing member 64; the two second limit switches 66 are both set toward the second moving block 63. The functions are the same as the two first limit switches 55 mentioned above. When the second movable block 63 moves close to the side wall of the second motor 61, it contacts a second limit switch 66. The second limit switch 66 immediately transmits an electrical signal to the second motor 61 and drives the second motor 61 to turn off, thereby preventing the second movable block 63 from moving to the end point of the second threaded rod 62. The second motor 61 continues to drive the second threaded rod 62 to rotate, so that the second movable block 63 always moves on the second threaded rod 62. Once the second movable block 63 is located at the end point of the second threaded rod 62, the second motor 61 is not turned off, causing the second movable block 63 to continue to move, thereby causing damage to the second movable block 63. The other second limit switch 66 has the same function and will not be repeated here.

[0043] Furthermore, the lifting device 6 also includes a second U-shaped optical coupler 67; the top wall of the second U-shaped optical coupler 67 is fixedly connected to the bottom wall of the second fixing piece 64, and the opening of the second U-shaped optical coupler 67 faces the objective lens 4; the end of the second threaded rod 62 away from the second motor 61 is fixedly installed with a second fixing ring 68 and the second fixing ring 68 is located below the second fixing piece 64 and has a gap, the second fixing ring 68 can rotate with the rotation of the second threaded rod 62, the second fixing ring 68 includes a second annular cylinder and a second straight plate, one side wall of the second straight plate is connected to one end of the second annular cylinder, one end of the second straight plate is placed in the opening of the second U-shaped optical coupler 67, which is used to measure the moving distance of the second moving block 63, so as to accurately measure the moving distance of the second moving block 63, and when moving the second moving block 63, the moving distance of the second moving block 63 can be accurately measured by the second U-shaped optical coupler 67, thereby realizing macro movement of the second moving block 63.

[0044] Furthermore, the track assembly 65 includes a first track 651 and a second track 652, and the first track 651 and the second track 652 are both retractable tracks; the first track 651 and the second track 652 correspond to the second motor 61 and the second fixing member 64 respectively, and the first track 651 and the second track 652 are both fixedly connected to the inner wall of the side panel 2 through a mounting seat. Since the end of the side plate 2 away from the mounting plate 1 is aesthetically pleasing and has a larger shadow area, relative protrusions are provided on the top, bottom and end close to the objective lens 4 of the two side plates 2, and the protrusions on the top, bottom and end close to the objective lens 4 of one side plate 2 are connected in sequence. In order to prevent the protrusions from affecting the horizontal movement of the lifting device 6, a fixing piece is provided to connect the first track 651 and the second track 652 to the inner wall of the side plate 2, so that the first track 651 and the second track 652 do not interfere with the protrusions, thereby enhancing the smoothness of the first track 651 and the second track 652; since the first track 651 and the second track 652 are set as retractable tracks, the moving distance of the second motor 61 and the second fixing piece 64 is increased. It is explained here that the longest length of the first track 651 and the second track 652 is the same as the maximum moving distance of the first moving block 53, which can drive the second moving block 63 to move with the movement of the first moving block 53, thereby driving the second motor 61 and the second fixing piece 64 to move along the first track 651 and the second track 652.

[0045] In addition, since the first track 651 and the second track 652 are both retractable tracks, elastic parts and limit rods can be set inside each track section. Through the elastic parts and the limit rods, when the transverse movement device 5 drives the lifting device 6 to move toward the eyepiece 3, the first track 651 and the second track 652 can move with the movement of the lifting device 6, thereby preventing the exposed first track 651 and the second track 652 from scratching the child's face.

[0046] In addition, the lifting device 6 and the lateral movement device 5 can also change the image distance of the eyepiece 3, wherein the eyepiece 3 is a concave mirror and the objective lens 4 is a convex mirror:

[0047] The imaging formula of a concave mirror is:

[0048]

[0049] The imaging formula of a convex mirror is:

[0050]

[0051] P2=X

[0052] The imaging formula of the virtual image projected by a concave mirror is:

[0053]

[0054] Wherein, q1 is the image distance of the image formed by the eyepiece 3;

[0055] P1 is the sum of the center distance between the eyepiece 3 and the objective lens 4 and the image distance presented by the objective lens 4;

[0056] f1 is the focal length of the concave mirror;

[0057] Y is the center distance between the eyepiece 3 and the objective lens 4;

[0058] q2 is the image distance of the objective lens 4;

[0059] P2 is the distance between the center of the book placed on the reading and writing platform and the center of the objective lens 4;

[0060] f2 is the focal length of the convex mirror;

[0061] X is the distance between the center of the book and the center of the objective lens 4 .

[0062] Through the above formulas, the distance of the virtual image projected by the eyepiece 3 can be calculated.

[0063] Furthermore, a multifunctional telescope of the present embodiment also includes a display screen 7, a timer 8, a speaker 9 and a camera 10; the display screen 7 is mounted on the shading cover 11 on the mounting plate 1 and the display direction of the display screen 7 faces the objective lens 4, and the timer 8 and the speaker 9 are both mounted on the display screen 7; the display screen 7, the timer 8 and the speaker 9 are electrically connected; the camera 10 is embedded in the display screen 7. By setting the display screen 7, texts can be displayed on the display screen 7, such as words such as appropriate relaxation and work-rest combination; the timer 8 and the speaker 9 are set, and the timer 8 can count the time of the child's study. When the child's study time reaches the specified time, the speaker 9 makes a sound, and the specific time of study also appears on the screen to remind the child; wherein the speaker 9 can play music or eye exercises, which is suitable for the child to relax. By setting the camera 10, parents can supervise the child's study situation or observe the situation around the child, so as to grasp the child's situation in real time and avoid the child from being in danger when leaving the child alone at home.

[0064] Through the above structure, the working principle of a multifunctional telescope of this embodiment is as follows:

[0065] like Figure 1-Figure 8 As shown, the device is first assembled. After the assembly is completed, the child adjusts the objective lens 4 according to his / her own height or position; the transverse movement device 5 and the lifting device 6 can be controlled by a remote controller or the like.

[0066] When the button of the main transverse movement device 5 on the remote controller is pressed, the first motor 51 is started, driving the first threaded rod 52 to rotate, and the first moving block 53 moves along the axis of the first threaded rod 52, thereby driving the lifting device 6 to move. At this time, the first track 651 and the second track 652 are extended or shortened due to the movement of the lifting device 6. When the objective lens 4 reaches the specified position, due to the height limit or the height limit of the seat, the objective lens 4 may block the child's sight. The button of the main lifting device 6 on the remote controller can be pressed to start the second motor 61, and the second motor 61 drives the second threaded rod 62 to rotate, thereby driving the second moving block 63 to move along the axis of the second threaded rod 62, that is, the objective lens 4 is vertically lowered, thereby changing the distance between the objective lens 4 and the reading and writing platform, so that children with shorter height or shorter seats can also see more clearly, and the image of the objective lens 4 reflected by the eyepiece 3 can also be clearer, and the image distance of the image will also change.
