Detailed Implementation

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0035] In one embodiment of this utility model, a zenith mirror for use in a telescope is provided, such as... Figure 1 and Figure 2 As shown, it includes a zenith mirror body 6 with a receiving cavity, an image sensor 8 disposed inside the zenith mirror body 6, and an optical path switching mechanism. The housing of the zenith mirror body 6 is provided with an eyepiece fine adjustment interface 5 and a light transmission hole 601 opposite to the image sensor 8.

[0036] The optical path switching mechanism includes a mounting bracket 1 fixedly connected to the zenith mirror body 6, a rotating shaft 2 passing through the mounting bracket 1, a reflector bracket 3 fixedly connected to the rotating shaft 2, and a servo motor 4 for driving. Under the drive of the servo motor 4, the rotating shaft 2 rotates relative to the mounting bracket 1.

[0037] The reflector bracket 3 is provided with a reflector on the side facing the eyepiece fine adjustment interface 5. The reflector bracket 3 has an initial first working position and a second working position after being driven by the servo motor 4.

[0038] like Figure 2 and Figure 4As shown, the reflector bracket 3 in the first working position does not interfere with the optical path from the light-passing aperture 601 to the image sensor 8. That is, the telescope is in imaging mode at this time, and the external light from the telescope passes through the lens barrel assembly 10 and directly reaches the image sensor 8. In this embodiment, the image sensor 8 is a CMOS component or a CCD component; Figure 1 As shown, when the reflector bracket 3 is in the second working position, the light passing through the light-transmitting hole 601 is reflected by the reflector on the reflector bracket 3 and then transmitted to the eyepiece fine-tuning interface 5. That is, at this time the telescope is in visual mode, and the light outside the telescope enters the eyepiece after being reflected by the telescope tube assembly 10.

[0039] Specifically Figure 1 The orientation shown is as follows: the image sensor 8 and the light-transmitting hole 601 are respectively set on the left and right vertical planes of the zenith mirror body 6, and the eyepiece fine-tuning interface 5 is set on the upper horizontal plane of the zenith mirror body 6.

[0040] The angle between the reflector on the reflector bracket 3 in the second working position and the horizontal plane ranges from 44° to 46°, preferably 45°.

[0041] In one embodiment of this utility model, when the reflector bracket 3 is rotated to the second working position, the reflector bracket 3 abuts against the zenith mirror body 6. For example... Figure 1 and Figure 2 As shown, the mounting bracket 1 is disposed on the upper inner wall surface of the zenith mirror body 6, and the reflector bracket 3 is a plate-shaped structure with a chamfered plane (not shown) at one end away from the rotating shaft 2.

[0042] like Figure 1 As shown, when the reflector bracket 3 is rotated to the second working position, the chamfered plane abuts against the lower inner wall surface of the zenith mirror body 6.

[0043] In this embodiment, the zenith mirror also includes a main control board 7 and an infrared proximity sensor 9. The main control board 7 is electrically connected to the image sensor 8, the servo motor 4, and the infrared proximity sensor 9.

[0044] The infrared proximity sensor 9 is configured to send a high-level trigger signal to the main control board 7 when it detects a thermal signal in the infrared band, thereby triggering the servo motor 4 to drive the reflector bracket 3 to rotate to the second working position. This sensing technology is used in existing technologies, such as in automatic flip-top toilets: when a person is sensed approaching, the toilet lid automatically flips up; when a person is sensed leaving, the toilet lid automatically closes. Similarly, in this embodiment of the present invention, when a person is detected approaching the telescope, the reflector bracket 3 is automatically driven to rotate from the first working position to the second working position, that is, the telescope switches from imaging mode to visual mode. This does not involve any improvement to the computer program.

[0045] In another embodiment or a further embodiment, the main control board 7 is also provided with a switch button, which is electrically connected to the main control board 7; the switch button is configured to trigger the main control board to send a drive command to the servo motor 4, that is, to trigger the servo motor 4 to drive the rearview mirror bracket 3 to rotate to the second working position by manually pressing the switch button.

[0046] In one embodiment of the present invention, a telescope is provided, including a telescope tube assembly 10, a focusing module, and a zenith mirror as described above. The focusing module includes a focusing base outer cylinder 11, a movable slip ring 12, a focusing base inner cylinder 13, a focusing base gear set 14, and a motor 15. The focusing module is configured to adjust the position of the lens in the telescope tube assembly.

[0047] Furthermore, the telescope also includes a communication module configured to communicate with a mobile terminal client using Bluetooth, NFC, or WiFi technology.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
