Description

Technical Field

[0001] The present invention relates to the technical field of target scopes, and more specifically, it relates to a target scope with a ranging function. Background Art

[0002] As a high-precision optical observation device, a target scope is widely used in shooting training and competition scenarios. Its core function is to assist in observing the distribution of bullet impacts by magnifying the target surface image, providing a basis for shooters to correct the ballistic trajectory.

[0003] Existing target scopes usually do not have a ranging function. Therefore, in some usage scenarios, they need to be used in conjunction with a laser rangefinder. However, the external module increases the volume of the device, making it inconvenient to carry and set up, especially limited in practicality in complex field terrains.

[0004] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a target scope with a ranging function.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: A target scope with a ranging function includes a target observing assembly and a ranging assembly;

[0007] The target observing assembly includes an objective lens group, a first reflector, a second reflector, a zoom lens group, and an eyepiece group;

[0008] The ranging assembly includes a laser emitting module, a laser emitting lens group, a laser receiving lens group, and a laser receiving module;

[0009] A transmissive display screen electrically connected to the laser receiving module is arranged between the zoom lens group and the eyepiece group, and a reticle is arranged between the second reflector and the zoom lens group.

[0010] The present invention is further configured as: The laser emitting module and the laser emitting lens group are arranged below the objective lens group. The first reflector is located on one side of the objective lens group and is inclined towards the optical axis. The second reflector, the laser receiving lens group, and the laser receiving module are arranged on the reflection optical path of the first reflector. The second reflector is inclined towards the optical axis. The zoom lens group and the eyepiece group are located on the reflection optical path of the second reflector.

[0011] The present invention is further configured as: Exchange the positions of the laser emitting module and the laser receiving module.

[0012] The present invention is further configured such that: the first reflector is a total reflector, and the surface of the second reflector is coated with a laser antireflection film, allowing the laser in the 905 nm band to penetrate and reflecting visible light in the 400 - 700 nm band.

[0013] The present invention is further configured such that: the laser receiving lens group and the laser receiving module are arranged on one side of the first reflector.

[0014] The present invention is further configured such that: the laser emitting module and the laser emitting lens group are arranged on the incident side of the first reflector. A beam splitting film is coated at the center of the surface of the first reflector. The beam splitting film allows the 905 nm laser to penetrate, and reflects visible light in the 400 - 700 nm band and the laser in the 905 nm band in the remaining areas. The laser emitted by the laser emitting module penetrates through the beam splitting film and is emitted from the objective lens group to the target. The second reflector, the laser receiving lens group and the laser receiving module are arranged on the reflection optical path of the first reflector, and the zoom lens group and the eyepiece group are located on the reflection optical path of the second reflector.

[0015] The present invention is further configured such that: the beam splitting film area is circularly arranged and located in the central area of the first reflector.

[0016] The present invention is further configured such that: the surface of the second reflector is coated with a laser antireflection film, allowing the laser in the 905 nm band to penetrate and reflecting visible light in the 400 - 700 nm band.

[0017] The present invention is further configured such that: the positions of the laser emitting module and the laser receiving module are exchanged.

[0018] The present invention has the following beneficial effects: After the laser emitting module emits laser, the laser is emitted through the laser emitting lens group and enters the laser light receiving lens group through reflection, and is finally received by the laser receiving module. After receiving the laser signal, the light receiving module calculates to obtain a distance signal, and the distance signal is displayed on the transmissive display screen. By integrally arranging the target viewing component and the distance measuring component, the volume of the device is reduced and its practicability is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively. Specific Embodiment 1:

[0029] As Figure 1 shown, a target-viewing telescope with a ranging function includes a target-viewing assembly and a ranging assembly;

[0030] The target-viewing assembly includes an objective lens group 1, a first reflector 2, a second reflector 3, a zoom lens group 4 and an eyepiece group 5;

[0031] The ranging assembly includes a laser emission module 6, a laser emission lens group 7, a laser reception lens group 8 and a laser reception module 9;

[0032] A transmissive display screen 10 electrically connected to the laser reception module 9 is provided between the zoom lens group 4 and the eyepiece group 5, and a reticle 11 is provided between the second reflector 3 and the zoom lens group 4.

[0033] After the laser emission module 6 emits laser light, the laser light passes through the laser emission lens group 7 and then enters the laser reception lens group 8 through reflection, and is finally received by the laser reception module 9. After receiving the laser signal, the laser reception module 9 calculates the distance signal and displays the distance signal on the transmissive display screen 10. By integrally arranging the target-viewing assembly and the ranging assembly, the volume of the device is reduced and its practicability is improved.

[0034] The laser emission module 6 and the laser emission mirror group 7 are arranged below the objective lens group 1. The first reflector 2 is located on one side of the objective lens group 1 and is inclined 20 - 50° towards the optical axis. The second reflector 3, the laser receiving mirror group 8 and the laser receiving module 9 are arranged on the reflection optical path of the first reflector 2. The second reflector 3 is inclined 10 - 40° towards the optical axis. The zoom lens group 4 and the eyepiece group 5 are located on the reflection optical path of the second reflector 3.

[0035] The first reflector 2 is a total reflector, which can totally reflect visible light and laser. After the visible light enters through the objective lens group 1, it is reflected by the first reflector 2 to the second reflector 3, and then reflected by the second reflector 3 to the zoom lens group 4 and the eyepiece group 5, enabling the user to observe an enlarged image.

[0036] The surface of the second reflector 3 is coated with a laser antireflection film, which allows the 905nm band laser to penetrate and reflects the visible light in the 400 - 700nm band. After the laser is reflected by the objective lens group 1, it enters the second reflector 3 under the action of the first reflector 2, and directly penetrates the second reflector 3 under the action of the laser antireflection film, and enters the laser receiving mirror group 8 and the laser receiving module 9, so as to calculate the distance information. Specific Embodiment 2:

[0038] As Figure 2 shown, different from Specific Embodiment 1, the positions of the laser emission module 6 and the laser receiving module 9 are exchanged (the laser emission mirror group 7 and the laser receiving mirror group 8 are of the same type of mirror group and do not need to be exchanged). After the laser is emitted and passes through the second reflector 3, the first reflector 2 can reflect the laser. After the laser is emitted from the objective lens group 1, the reflected laser can enter the laser receiving module 9. Specific Embodiment 3:

[0040] As Figure 3 shown, different from Specific Embodiment 1, the laser receiving module 9 and the laser receiving mirror group 8 are arranged on one side of the first reflector 2. The surface of the first reflector 2 is coated with a laser antireflection film, which allows the 905nm band laser to penetrate and reflects the visible light in the 400 - 700nm band. The second reflector 3 can reflect the visible light in the 400 - 700nm band. The laser emitted by the laser emission module 6 can pass through the eyepiece group and the first reflector 2 after being reflected back, and enter the laser receiving module 9. Specific Embodiment 4:

[0042] As Figure 4As shown, different from Specific Embodiment 3, the positions of the laser emission module 6 and the laser receiving mirror group 8 are exchanged. A laser antireflection film is coated on the surface of the first mirror 2, allowing the 905 nm band laser to penetrate and reflecting visible light in the 400 - 700 nm band. The second mirror 3 is a total reflection mirror. The laser passes through the beam splitting film 12 on the second mirror 2 and then exits from the objective lens group, and the reflected laser enters the laser receiving module 9. Specific Embodiment 5:

[0044] As Figure 5 different from Figure 6 shown, different from Specific Embodiment 1, the laser emission module 6 and the laser emission mirror group 7 are arranged on one side of the first mirror 2. A beam splitting film 12 is coated in the central area of the surface of the first mirror 2. The beam splitting film 12 allows the 905 nm laser to penetrate, and the remaining area reflects visible light in the 400 - 700 nm band and the 905 nm band laser. The laser emitted by the laser emission module 6 passes through the beam splitting film 12 and then exits from the objective lens group 1 to the target. The second mirror 3, the laser receiving mirror group 8 and the laser receiving module 9 are arranged on the reflection optical path of the first mirror 2, and the zoom lens group 4 and the eyepiece group 5 are located on the reflection optical path of the second mirror 3.

[0045] After the laser is emitted from the laser emission module 6 and passes through the laser emission mirror group 7, it penetrates through the beam splitting film 12 area of the first mirror 2 and finally exits from the objective lens group 1. After the reflected laser enters the target viewing mirror from the objective lens group 1, it is reflected by the outer area of the beam splitting film 12 of the first mirror 2, passes through the second mirror 3, and enters the laser receiving mirror group 8 and the laser receiving module 9.

[0046] The beam splitting film 12 area is circularly arranged and located in the central area of the first mirror 2, avoiding the occlusion of the observation optical path caused by coating the entire surface, so that while allowing the laser to penetrate, the peripheral area of the beam splitting film 12 can still reflect visible light and echo laser.

[0047] A laser antireflection film is coated on the surface of the second mirror 3, allowing the 905 nm band laser to penetrate and reflecting visible light in the 400 - 700 nm band, ensuring that the echo laser penetrates while reflecting visible light to the eyepiece group 5.

[0048] Specific embodiments are only explanations of the present invention, and they are not limitations of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment as needed after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
