Description

Technical Field

[0001] The utility model relates to the field of telescopes, in particular to a laser ranging telescope with a compact structure. Background Art

[0002] The imaging principle of a telescope is to use lenses, reflectors and other optical devices to observe distant objects, and to use the refraction of light passing through the lens or the reflection of light by a concave mirror to make it enter a small hole and converge to form an image, which is then seen through a magnifying eyepiece. It is also called a "telescope".

[0003] In order to measure the distance between the target object and the telescope, a laser transmitting PCB board and a laser receiving PCB board are usually added to the telescope. Figure 4 In the existing laser ranging telescope, the laser transmitting PCB board is arranged close to the eyepiece assembly and on the side of the prism assembly. A transmitting convex mirror assembly is arranged between the laser transmitting PCB board and the prism assembly for focusing light. A receiving convex mirror assembly is arranged next to the objective lens assembly. The laser receiving PCB board is arranged close to the receiving convex mirror assembly. There is a distance between the laser receiving PCB board and the laser transmitting PCB board. After the laser transmitting PCB board emits laser, the laser is reflected onto the target object through the prism assembly, and then the receiving convex mirror assembly focuses the laser light reflected by the target object onto the laser receiving PCB board.

[0004] Regarding the above-mentioned related technologies, after adding the laser emission and receiving structures, the overall size of the telescope is large, and female users usually need to use both hands to support it for easy use, which is inconvenient for female users to operate the telescope with one hand.

[0022] The embodiment of the present application discloses a laser ranging telescope with a compact structure.

[0023] Reference Figure 1-4 The compact laser ranging telescope includes a housing 1, in which an eyepiece assembly 2, an objective lens assembly 3, and a prism assembly 4 are arranged. The center line of the eyepiece assembly 2 and the center line of the objective lens assembly 3 are on the same axis, and the prism assembly 4 is located between the eyepiece assembly 2 and the objective lens assembly 3.

[0024] A laser emitting PCB board 5 is provided on the side of the casing 1, a laser receiving PCB board 6 is provided on the top surface of the casing 1, an emitting reflector 7 is provided between the laser emitting PCB board 5 and the laser receiving PCB board 6, and a receiving reflector 8 is provided between the emitting reflector 7 and the prism assembly 4.

[0025] An emitting convex mirror assembly 9 is provided next to the objective lens assembly 3 , and the emitting reflector 7 reflects the laser emitted by the laser emitting PCB board 5 to the emitting convex mirror assembly 9 and focuses the laser light to the target object through the emitting convex mirror assembly 9 .

[0026] A receiving convex mirror assembly 10 is provided between the prism assembly 4 and the receiving reflector 8 . The prism assembly 4 reflects the laser light to the receiving convex mirror assembly 10 and focuses the laser light onto the receiving reflector 8 through the receiving convex mirror assembly 10 .

[0027] A mainboard 11 is provided on the casing 1 and is installed on the bottom surface of the casing 1. The mainboard 11 is electrically connected to the laser emitting PCB board 5 and the laser receiving PCB board 6. A timing module is provided in the mainboard 11, which records the time from the laser emitting PCB board 5 emitting the laser to the laser receiving PCB board 6 receiving the laser.

[0028] During laser ranging, the laser emitting PCB board 5 emits laser toward the emitting reflector 7. The emitting reflector 7 reflects the laser emitted by the laser emitting PCB board 5 to the emitting convex mirror assembly 9 and focuses the laser light to the target object through the emitting convex mirror assembly 9. The target object forms an inverted image on the prism assembly 4 through the objective lens assembly 3. The prism assembly 4 reflects the laser light to the receiving convex mirror assembly 10 and focuses the laser light to the receiving reflector 8 through the receiving convex mirror assembly 10. The receiving reflector 8 then reflects the laser light to the laser receiving PCB board 6. According to the propagation speed of light in the air and the time from the laser emitting PCB board 5 emitting the laser to the laser receiving PCB board 6 receiving the laser, the distance between the target object and the telescope is finally calculated by an algorithm, thereby being able to measure the distance between the target object and the telescope.

[0029] After the emitting convex mirror assembly 9 focuses the laser onto the target object, the target object forms an inverted image on the prism assembly 4 through the objective lens assembly 3, and the prism assembly 4 then reflects the light of the target object to the eyepiece assembly 2 for inverted magnified imaging.

[0030] The emitting convex mirror assembly 9 is close to the objective lens assembly 3 and is arranged parallel to the objective lens assembly 3. The laser emitting PCB board 5 emits the laser to the target object through the small emitting reflector 7 and the emitting convex mirror assembly 9. The laser receiving PCB board 6 is arranged on the top surface of the casing 1, and receives the laser reflected by the target object through the small receiving reflector 8 and the receiving convex mirror assembly 10. The laser emitting structure next to the eyepiece assembly 2 in the existing laser ranging telescope is eliminated, and the space on the telescope is fully utilized, making the overall structure compact and reducing the structure of the overall laser ranging telescope, which is convenient for female users to operate the telescope with one hand.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
