Description
Technical Field
[0001] This utility model relates to the field of telescope technology, and in particular to an astronomical telescope. Background Technology
[0002] Since ancient times, humankind has observed and explored the celestial sphere. With the continuous development of technology, people began using various auxiliary instruments (such as astrolabes and telescopes) to improve the accuracy and efficiency of observations. Existing astronomical telescopes are mainly divided into two categories: optical eyepiece telescopes and electronic eyepiece telescopes. Optical eyepiece telescopes allow observers to directly and clearly observe images, while electronic eyepiece telescopes convert observed images into digital signals, which are then displayed on a screen for easy recording and analysis.
[0003] In existing technologies, to meet different observation needs, optical eyepiece telescopes and electronic eyepiece telescopes are combined into eyepiece assemblies. The eyepiece assembly contains a reflector inside its tube. By adjusting the tilt angle of the reflector, light can be selectively reflected onto either the optical or electronic eyepiece unit, allowing the observer to view images through different eyepiece units. However, using this type of eyepiece assembly for astronomical observation requires repeated and multiple adjustments to the reflector's tilt angle. This process is cumbersome, time-consuming, and inefficient. Furthermore, an incorrect tilt angle of the reflector directly affects the observation results. Utility Model Content

[0020] This invention provides an astronomical telescope, including a tube assembly, an eyepiece unit, a beam splitter assembly, and a frame assembly. When using this telescope to observe the night sky, the angle of the tube is adjusted so that the light inlet is aligned with the object to be observed.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0034] This embodiment provides an astronomical telescope, such as Figure 1 and Figure 2 As shown, the structure is simple, easy to operate, and can improve work efficiency and ensure the accuracy of observation results.
[0035] like Figure 1 and Figure 2As shown, the astronomical telescope includes a telescope tube assembly 1, an eyepiece unit 2, a beam splitter assembly 3, and a frame assembly 4. The telescope tube assembly 1 includes a tube body 11 and a lens 12. The tube body 11 has a light inlet and a light inlet channel 111, which are connected. The lens 12 is disposed within the light inlet channel 111. The eyepiece unit 2 includes a main housing 21, an optical eyepiece 22, and an electronic eyepiece assembly 23. The main housing 21 is detachably connected to the tube body 11 and is located at the end of the light inlet channel 111 opposite to the light inlet. The main housing 21 has a receiving chamber 211 and a light outlet, which is connected to the light inlet channel 111 through the receiving chamber 211. The optical eyepiece 22 is disposed at the light outlet, and the electronic eyepiece assembly 23 is disposed within the receiving chamber 211, located at the end of the receiving chamber 211 opposite to the light inlet channel 111. The beam splitter 3 is disposed in the receiving chamber 211. The beam splitter can disperse the light beam into two non-overlapping beams and propagate the two beams to the electronic eyepiece assembly and the optical eyepiece, respectively.
[0036] The beam splitter assembly 3 includes a beam splitter 31, a first reflector 32, and a second reflector 33. The principal optical axis of the beam splitter 31 is coaxial with the principal optical axis of the lens 12. The beam splitter 31 is used to disperse the light beam into two non-overlapping beams, which are then propagated to the first reflector 32 and the second reflector 33, respectively. Therefore, when a beam of light propagates to the beam splitter 31, it disperses the beam into two beams, which are then propagated to the first reflector 32 and the second reflector 33, respectively. The principal optical axis of the first reflector 32 is coaxial with the optical axis of the electronic eyepiece assembly 23, and the principal optical axis of the second reflector 33 is coaxial with the optical axis of the optical eyepiece 22. This ensures that the two beams are reflected by the first reflector 32 and the second reflector 33, respectively, to the electronic eyepiece assembly 23 and the optical eyepiece 22. The frame assembly 4 is detachably connected to the cylinder 11 and is used to support and mount the cylinder 11.
[0037] When using this telescope, first connect the tube body 11 to the frame assembly 4 so that the frame assembly 4 supports and supports the tube body 11. Then adjust the angle of the tube body 11 so that the light inlet is aligned with the object to be observed. The light beam enters the light inlet through the lens 12. Then the light beam will propagate along the light inlet channel 111 and the receiving chamber 211 and propagate to the beam splitter 31. The beam splitter 31 will split the light beam into two non-overlapping beams and propagate the two beams to the first reflector 32 and the second reflector 33 respectively. Then the beam propagated to the first reflector 32 is reflected to the electronic eyepiece assembly 23, thereby forming an image for the user to analyze and record. The beam propagated to the second reflector 33 is reflected to the optical eyepiece 22, and the user can directly observe the object through the optical eyepiece 22. By setting up the beam-splitting component 3, the astronomical telescope can both observe physical objects and record images at the same time. Therefore, it is not necessary to repeatedly adjust the angle of the reflector, avoiding observation errors caused by incorrect adjustment of the reflector angle. The structure is simple, easy to operate, and can improve work efficiency and ensure the accuracy of observation results.
[0038] For example, beam splitter 31 includes a beam splitting prism. In other embodiments, a planar beam splitter may be selected as beam splitter 31 as needed, which is not limited here.
[0039] Optionally, such as Figure 1 and Figure 2 As shown, the astronomical telescope also includes a clamping member, and the main housing 21 is provided with a connecting channel 112. The connecting channel 112 extends into the light-entry channel 111 of the tube 11, and the outer wall of the tube 11 has a threaded hole. The clamping member passes through the threaded hole and is threadedly connected to the inner wall of the threaded hole, and the clamping member is clamped against the outer wall of the connecting channel 112. When the telescope needs to be stored, the clamping member can be rotated to unscrew the threaded hole, thereby separating the clamping member from the outer wall of the connecting channel 112 and releasing the clamping effect of the clamping member on the connecting channel 112. Then, the connecting channel 112 of the main housing 21 can be pulled out of the light inlet channel 111 of the tube 11, thereby separating the eyepiece assembly and the tube assembly 1. Similarly, when assembling the telescope, the connecting channel 112 of the main housing 21 is inserted into the light inlet channel 111 of the tube 11, and then the clamping member is screwed into the threaded hole, and one end of the clamping member is clamped to the outer wall of the connecting channel 112. The structure is simple, the operation is convenient, and the replacement and assembly of parts are easy.
[0040] For example, the clamping element includes a screw. In other embodiments, other types of connecting accessories, such as bolts or threaded rods, may be selected as fasteners as needed, and are not limited here.
[0041] Optionally, such as Figure 1 and Figure 2As shown, the electronic eyepiece assembly 23 includes an image sensor 231, a circuit board 232, and a display screen 233. The image sensor 231 faces the first reflector 32 and is mounted on the circuit board 232. The display screen 233 is located on the side of the circuit board 232 away from the image sensor 231, and both the image sensor 231 and the display screen 233 are electrically connected to the circuit board 232. When the light beam propagates to the beam splitter 31, it is dispersed into two beams. One of these beams propagates to the first reflector 32 and is then reflected back to the image sensor 231. The image sensor 231 converts the light signal into an electrical signal, which is then processed by the circuit board 232 and transmitted to the display screen 233, allowing the display screen 233 to display an image, enabling the observer to observe and record. Therefore, using this astronomical telescope for astronomical observation eliminates the need for additional devices such as mobile phones or tablets, making it more convenient.
[0042] like Figure 1 and Figure 2 As shown, the electronic eyepiece assembly 23 also includes a filter 234. The filter 234 faces the first reflector 32 and is positioned between the first reflector 32 and the image sensor 231. When light is dispersed and propagates to the first reflector 32, the first reflector 32 reflects the dispersed light onto the filter 234, where it is filtered before propagating to the image sensor 231. By using the filter 234, unwanted light can be filtered out, allowing light of specific wavelengths to pass through, thereby enhancing the contrast and clarity of the image.
[0043] For example, the first reflector 32 includes a right-angle prism or a plane reflector, and the second reflector 33 includes a roof prism, etc.
[0044] Optionally, such as Figure 1 and Figure 2 As shown, the frame assembly 4 includes a mounting base plate (not shown), a mounting base 41, and multiple supports 42. The mounting base plate is disposed on the outer wall of the cylindrical body 11, and the multiple supports 42 are rotatably mounted on the mounting base 41. A limiting groove is provided at the end of the mounting base 41 opposite to the supports 42, and a limiting protrusion is provided on the side of the mounting base plate opposite to the cylindrical body 11. The limiting protrusion is detachably engaged within the limiting groove. When setting up the astronomical telescope, the multiple supports 42 are rotated to support it on the ground, and then the limiting protrusion on the mounting base plate is engaged within the limiting groove. When disassembling, simply separate the limiting protrusion from the limiting groove.
[0045] In this embodiment, three supports 42 are provided. In other embodiments, more than three supports 42 may be provided as needed, and this is not limited here.
[0046] It should be noted that in other embodiments, the limiting groove may be disposed on the mounting base plate and the limiting protrusion may be disposed on the mounting base 41, which is not limited here.
[0047] Optionally, such as Figure 1 and Figure 2 As shown, the astronomical telescope also includes a protective shield 5. The protective shield 5 is mounted on the body 11 and located at the light inlet. By using the protective shield 5, aberrations during light propagation can be reduced, improving image quality and resulting in clearer, sharper images.
[0048] Optionally, such as Figure 1 and Figure 2 As shown, the telescope tube assembly 1 also includes a focusing tube 6. The focusing tube 6 is disposed between the tube body 11 and the main housing 21 and is used to adjust the focal length to ensure image sharpness and color reproduction, thereby ensuring the best observation effect.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
