[0002] Today, scopes are commonly installed on shooting equipment such as bows and arrows and firearms, effectively helping users improve shooting accuracy. However, scopes estimate target distance based on the markings on their reticles, which is highly subjective and limited, inevitably leading to errors. With the development of laser technology, laser rangefinding technology has begun to be used in various scopes, greatly improving the accuracy and speed of rangefinding. However, integrating laser rangefinding components with scopes requires corresponding adjustments or modifications to the original scope's optical path design and structure, resulting in higher costs. Summary of the Invention

Therefore, they should not be construed as limitations on this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] See Figures 1 to 4 , Figure 1 The present application illustrates an aiming device 1, which has a rangefinder 2 detachably mounted on a sight 10. Figures 2 to 4 The structure of the rangefinder at various angles is shown. See further details. Figures 5 to 7 The rangefinder 2 includes a housing 20, and a power supply 21, a control module 22, a laser rangefinder module 30, a visible laser designator 32, a display module 40, and an optical diopter adjustment system 50 housed within the housing 20. The housing 20 is detachably mounted on the sight 10. In this embodiment, the sight 10 has an eyepiece 11 and a reticle 12 located in front of the eyepiece 11. The housing 20 of the rangefinder 2 is mounted on the eyepiece tube of the sight 10. The power supply 21 and the control module 22 are both fixed to one side inside the housing 20, and the display module 40 is fixed near the rear of the housing 20.

[0035] The laser ranging module 30, display module 40, and power supply 21 are all electrically connected to the control module 22. The optical path of the laser ranging module 30 and the optical path of the visible laser pointer 32 are coaxial. The visible laser pointer 32 is used to indicate the position when the ranging aiming position of the laser ranging module 30 is aligned with the center of the dividing plate 12 of the aiming scope 10. The image displayed by the display module 40 is adjusted by the optical diopter adjustment system 50 to suit the viewing habits of different users. The image displayed by the display module 40 makes the ranging data visible within the eyepiece field of view of the aiming scope 10 through the optical diopter adjustment system 50. The image displayed by the display module 40 is the ranging and related information of the laser ranging module 30. Specifically, the optical diopter adjustment system 50 adjusts the direction of the light path emitted from the display module 40. The optical diopter adjustment system 50 is used to fold and reflect the image displayed by the display module 40 into the eyepiece field of view of the aiming scope 10, so that the image displayed by the display module 40 is visible within the eyepiece field of view of the aiming scope 10. Meanwhile, the optical diopter adjustment system 50 also has a diopter adjustment function. By adjusting the diopter through the optical diopter adjustment system 50, the rangefinder can be adapted to the diopter of different users. That is to say, the light emitted by the display module 40 is refracted and redirected by the optical diopter adjustment system 50, so that the light path is projected into the user's eyes. In this way, within the eyepiece field of view of the sight 10, the user can observe the image of the target obtained by the sight 10 and the range measurement image and range measurement information of the target obtained by the rangefinder 2. There is no need to redesign or modify the structure and optical path of the original sight 10, thus reducing costs. The setting of the optical diopter adjustment system 50 allows the rangefinder to be adapted to the observation habits of different users. Whether the user's eyes are nearsighted or farsighted, or whether the user is accustomed to being far or close to the eyepiece, the image shown by the display module 40 can be clearly observed through the adjustment of the optical diopter adjustment system 50.

[0036] Compared with the prior art, the rangefinder 2 provided in this application is mounted on the sight 10. Users can use the sight 10 normally according to their original usage habits. They can directly observe the range data within the eyepiece field of view of the original sight 10 without making any modifications or adjustments to the original sight 10. It is simple and convenient to use and saves costs.

[0037] Further reading Figures 5 to 7The housing 20 includes a receiving portion 201 and a connecting portion 202. When the rangefinder 2 is mounted on the eyepiece tube of the sight 10, the receiving portion 201 is located directly above the connecting portion 202. The power supply 21, control module 22, laser rangefinder module 30, display module 40, and optical diopter adjustment system 50 are all housed within the receiving portion 201. The connecting portion 202 is fitted onto the eyepiece tube of the sight 10. The connecting portion 202 has a rotatable support leg 204, which is connected and fixed to the connecting portion 202 by fasteners to lock the connecting portion 202 onto the eyepiece tube of the sight 10. In this embodiment, one end of the support leg 204 is rotatably connected to the bottom side of the joint 202, and the other end of the support leg 204 is fixed to the top side of the joint 202 by screws. When it is necessary to remove the rangefinder 2 from the sight 10, the screws are unscrewed, and the support leg 204 is rotated to open, so that the rangefinder 2 can be removed from the sight 10. The installation and removal of the rangefinder 2 is convenient. Understandably, the housing 20 can also be installed on the eyepiece tube of the sight 10 by other detachable methods such as clips or screws.

[0038] See Figures 7 to 10 The laser ranging module 30 includes a laser ranging unit 31. The laser ranging unit 31 is electrically connected to the control module 22 to provide ranging information. The visible laser pointer 32 is electrically connected to the control module 22. The visible laser pointer 32 is used to receive natural light and form an image. The visible laser pointer 32 emits a visible laser beam towards a target 4 and forms a ranging aiming point on the target 4.

[0039] In this embodiment, the laser ranging unit 31 includes a laser emitting unit 310 and a laser receiving unit 320. The laser emitting unit 310 is used to emit a laser beam to a target 4, and the laser receiving unit 320 is used to receive the reflected laser beam. The laser emitting unit 310 forms a laser emitting optical path 303, and the laser receiving unit 320 forms a laser receiving optical path 304. The visible laser pointer 32 forms a natural light observation optical path 305. The axes of the laser emitting optical path 303, the laser receiving optical path 304, and the natural light observation optical path 305 are coaxial and their axes overlap.

[0040] Specifically, the laser emitting unit 310 includes a laser emitter 311 for emitting a laser beam and a laser reflector 312 for reflecting the laser beam. The laser emitter 311 is positioned above the laser reflector 312, which is inclined with its top tip tilted towards the rear of the housing 20. The laser receiving unit 320 includes a laser receiving mirror 321 for converging the laser beam diffusely reflected from the target 4 and a laser receiver 322 for receiving the converged laser beam. The laser receiver 322 converts the received optical signal into an electrical signal.

[0041] The control module 22 includes a processing unit and a calculation unit. The processing unit records the time between laser emission and return, and the calculation unit calculates the distance to target 4 based on the time and laser speed. Optionally, the upper shell of the control module 22 is equipped with one or more of the following: an angle sensor, a temperature and humidity sensor, a barometric pressure sensor, a wind speed and direction sensor, a satellite positioning system, and a wireless transmission module. The angle sensor is used to perform comprehensive angle measurement of target 4; the temperature and humidity sensor is used to measure the temperature and humidity of the surrounding environment; the barometric pressure sensor is used to measure the air pressure of the surrounding environment; the wind speed and direction sensor is used to measure the wind speed and direction of the surrounding environment; and the satellite positioning system is used to receive global positioning data of target 4, such as latitude, longitude, and altitude. In other words, the ranging-related information of the laser ranging module can include data such as the temperature, humidity, air pressure, wind speed, and wind direction of the surrounding environment. The computing unit can correct the calculation results based on data such as temperature, humidity, air pressure, wind speed, and wind direction detected by the laser ranging module 30. This allows for the display of more ranging information on the display module 40, overcoming the influence of various environmental factors and ensuring accuracy during firing. The wireless transmission module can transmit laser data and data from other sensors to the terminal device. An external interface 206 is also provided on the side of the housing 20. This external interface 206 can be, but is not limited to, a USB or Type-C interface, and can be electrically connected to external devices for data transmission.

[0042] The visible laser pointer 32 and laser receiver 322 transmit electrical signals to the control module 22. The control module 22 processes the received electrical signals, so that the ranging information and the ranging aiming point are simultaneously displayed on the display module 40. The display module 40 then uses the optical diopter adjustment system 50 to fold and reflect the image into the eyepiece's field of view. Specifically, the display module 40 includes a display driver circuit board 41 and a display screen 42 mounted on the display driver circuit board 41. The display screen 42 can be, but is not limited to, an OLED display screen, a TFT display screen, an LED display screen, an LCD display screen, and a digital tube display screen.

[0043] See Figure 2 , Figure 5 , Figure 7 and Figure 10The rear of the housing 20 has a rear cover 203 with multiple buttons. One of these buttons is a rangefinder button 207. After aiming at the target 4, triggering the rangefinder button 207 drives the control module 22 to generate a signal. The laser emitter 311 receives the signal and emits a laser beam. The laser beam is reflected by the laser reflector 312 to form a rangefinder laser beam that is directed towards the target 4 and reflected to the laser receiver 321. The laser receiver 321 directs the reflected laser beam to the laser receiver 322, which converts the received light signal into an electrical signal. This electrical signal is then transmitted to the control module 22. The control module 22 processes these electrical signals and transmits the processed data to the display screen 42 to directly display the measurement results. Optionally, electrical signals from the angle sensor, temperature and humidity sensor, barometric pressure sensor, and wind speed and direction sensor are also transmitted to the control module 22 for processing, and the processed results can also be displayed on the display screen 42. The back cover 203 also has two brightness adjustment buttons 208. Triggering the corresponding brightness adjustment button 208 can adjust the brightness of the image display.

[0044] The housing 20 also includes an inner housing 302, in which at least a portion of the laser ranging unit 31 and the visible laser designator 32 are housed and fixed. The inner housing 302 is movably disposed within the housing 20 via a first adjusting member 23. The first adjusting member 23 allows adjustment of the ranging aiming position of the laser ranging module 30 to coincide with the center of the dividing plate 12 of the aiming scope 10, i.e., adjusting the ranging aiming point of the visible laser designator 32 to coincide with the center of the dividing plate 12 of the aiming scope 10. Specifically, the inner housing 302 has ball joint structures that mate with the housing 20 on its upper and lower sides and / or left and right sides. The ball joint structures on the upper and lower sides are coaxially arranged, and the ball joint structures on the left and right sides are coaxially arranged. The inner housing 302 is rotatably connected to the housing 20 via these ball joint structures, meaning the inner housing 302 is rotatably mounted within the housing 20 using a ball joint configuration. In this embodiment, the first adjusting member 23 is configured as a sleeve-shaped structure with a spherical head surface. The first adjusting member 23 includes a spherical head surface 231 disposed on the top side of the receiving part 201 and on the bottom side of the receiving part 201. The spherical head surface 231 on the top side is concave upward and the spherical head surface 231 on the bottom side is concave downward. The inner shell 302 is provided with protruding spherical heads 301 corresponding to the positions of each spherical head surface 231. The spherical heads 301 on both sides of the inner shell 302 match the spherical head surface 231 on the corresponding side. The spherical head surface 231 and the spherical head surface 231 on the corresponding side form a spherical pair structure. The inner shell 302 is rotatably installed in the housing 20 through the cooperation of the spherical head 301 and the spherical head surface 231. The housing 20 is equipped with a horizontal adjustment knob 24 and a vertical adjustment knob 25. The horizontal adjustment knob 24 drives the inner housing 302 to rotate horizontally relative to the housing 20, and the vertical adjustment knob 25 drives the inner housing 302 to rotate vertically relative to the housing 20. This allows the inner housing 302 to rotate within the housing 20, aligning the rangefinding aiming point of the visible laser designator 32 with the center of the dividing plate 12 of the sight 10. In other words, when the rangefinder 2 is initially installed on the sight 10, the rangefinding aiming point and the center of the dividing plate 12 of the sight 10 may not be aligned. In this case, the aiming point of the rangefinding aiming point and the center of the dividing plate 12 of the sight 10 may not be aligned when the horizontal adjustment knob 24 and the vertical adjustment knob 25 are turned to align them. Then, the position of the inner housing 302 within the housing 20 is locked, and no further adjustment is required. When the corresponding shooting device 3 is used multiple times and it is found that the center of the rangefinding aiming point and the center of the dividing plate 12 do not coincide, it can be readjusted again by using the horizontal adjustment knob 24 and the vertical adjustment knob 25 to make the aiming points of the two coincide.

[0045] Understandably, ball joints can also be coaxially arranged on the left and right sides of the inner shell 302, and a ball joint surface can be provided on the housing 20 corresponding to the position of the ball joint. In this way, the inner shell 302 is rotatably mounted in the receiving part 201 of the housing 20 in a ball joint manner. Alternatively, ball joints can be provided on the left and right sides and the top and bottom sides of the inner shell 302, with the ball joints on the left and right sides coaxially arranged and the ball joints on the top and bottom sides coaxially arranged, and a ball joint surface can be provided on the housing 20 corresponding to the position of the ball joint. In other embodiments, ball joint surfaces can also be coaxially arranged on the left and right sides of the inner shell 302, and a ball joint can be provided on the housing 20 corresponding to the position of the ball joint surface.

[0046] Preferably, see Figures 5 to 7 The housing 20 is equipped with a locking member 230. When the ranging aiming point of the visible laser pointer 32 is adjusted to coincide with the center of the dividing plate 12 of the aiming scope 10 by adjusting the horizontal adjustment knob 24 and the vertical adjustment knob 25, the inner shell 302 can be locked and fixed inside the housing 20 by the locking member 230. In this embodiment, the top surface of the housing 20 is provided with a threaded hole, and the locking member 230 is threaded into the threaded hole. The bottom surface of the locking member 230 forms the ball head surface 231 on the top side of the first adjusting member 23. When the locking member 230 is screwed out, the inner shell 302 is in a rotatable state. When the locking member 230 is screwed in to a certain distance, the inner shell 302 is locked. At this time, the inner shell 302 is fixed relative to the housing 20 and is in a non-rotatable state. The housing 20 is provided with a fixed seat 240, and a ball head seat 241 is provided on the fixed seat 240. The top surface of the ball head seat 241 is recessed to form the ball head surface 231 on the bottom side of the first adjusting member 23. The ball head surfaces 231 on the upper and lower sides are coaxially arranged in the vertical direction.

[0047] See Figure 2 and Figures 5 to 7 The display module 40 and the optical diopter adjustment system 50 constitute the ranging data display system 3. Part of the optical diopter adjustment system 50 is movably mounted within the housing 20 via a second adjusting member 26. After adjusting the second adjusting member 26, the optical diopter of the ranging data display system 3 can be adjusted to be the same as the optical diopter of the sight 10. In this embodiment, the optical diopter adjustment system 50 includes multiple reflectors. Some of the reflectors are movably mounted within the housing 20 via the second adjusting member 26. Thus, after adjusting the second adjusting member 26, the optical diopter of the ranging data display system 3 can be adjusted to be the same as the optical diopter of the sight 10. That is, after adjusting the second adjusting member 26, the total optical path size of the optical diopter adjustment system 50 changes, thereby achieving diopter adjustment. After diopter adjustment, the optical diopter of the ranging data display system 3 can be equivalent to the original optical diopter of the sight 10, allowing the user to observe the ranging value while using the original sight 10 normally.

[0048] The housing 20 is provided with a diopter adjustment knob 27, which is connected to the second adjustment member 26. By rotating the diopter adjustment knob 27, the second adjustment member 26 can be driven to move relative to the housing 20, thus realizing diopter adjustment.

[0049] Specifically, the second adjusting component 26 includes a screw 261 and a diopter adjustment seat 262 disposed within the housing 20. The screw 261 is rotatably connected to the housing 20, and specifically, both ends of the screw 261 are rotatably connected to the housing 20 via bearings. The diopter adjustment seat 262 is slidably fitted to the housing 20. The diopter adjustment seat 262 is screwed onto the screw 261, and the diopter adjustment knob 27 is connected to one end of the screw 261. Some of the reflectors in the optical diopter adjustment system 50 are fixed to the diopter adjustment seat 262. When the diopter adjustment knob 27 is rotated, the screw 261 rotates accordingly, and the screw 261 drives the diopter adjustment seat 262 to move along the front-back direction of the housing 20. The housing 20 may be equipped with a slide rod or slide rail, and the diopter adjustment seat 262 is slidably engaged with the slide rod or slide rail. The axis of the slide rod or slide rail is parallel to the front-rear direction of the housing 20, so that the diopter adjustment seat 262 is slidably assembled in the housing 20 via the slide rod or slide rail. In this embodiment, the housing 20 is provided with at least one slide rod 263, and the diopter adjustment seat 262 is slidably engaged with each slide rod 263.

[0050] Specifically, the optical diopter adjustment system 50 includes a first reflector 51, a second reflector 52, a third reflector 53, a fourth reflector 54, a fifth reflector 55, and a sixth reflector 56. The first reflector 51 and the second reflector 52 are arranged parallel to each other and spaced apart, with the second reflector 52 located directly above the first reflector 51. Their mirror surfaces face each other, and the top of the first reflector 51 is angled towards the front of the housing 20. The third reflector 53 and the fourth reflector 54 are arranged adjacent to each other at a 90-degree angle, with the fourth reflector 54 located above the third reflector 53. The third reflector 53 and the second reflector 52 are arranged parallel to each other and spaced apart. The fifth reflector 55 and the sixth reflector 56 are arranged parallel to each other and spaced apart. The sixth reflector 56 is located directly above the fifth reflector 55, and its mirror surface faces the light-emitting surface of the display module 40. The top of the sixth reflector 56 is tilted towards the display module 40. The fifth reflector 55 and the fourth reflector 54 are arranged parallel to each other and spaced apart. The light emitted by the display module 40 is first reflected by the sixth reflector 56, and then sequentially reflected by the fifth reflector 55, the fourth reflector 54, the third reflector 53, and the second reflector 52, and finally reflected by the first reflector 51 into the field of view of the eyepiece 11. The tilt angle of the first reflector 51 can be set according to the field of view of the eyepiece 11 of the aiming scope 10, so that the light reflected from the first reflector 51 falls into the field of view of the eyepiece 11. The bottom side of the rear cover 203 of the housing 20 is provided with a light outlet 205, and a lens is vertically arranged at the light outlet 205. The light emitted by the first reflector 51 enters the field of view of the eyepiece after exiting through this lens.

[0051] Understandably, the optical diopter adjustment system 50 can also use other numbers of mirrors, and the positions of the mirrors can also be adjusted accordingly, as long as these mirrors meet the conditions for reflection imaging and can fold and reflect the light emitted by the display screen 42 into the field of view of the eyepiece.

[0052] Preferably, the optical diopter adjustment system 50 further includes multiple convex lenses. Multiple convex lenses are disposed within the housing 20 along the optical path of the optical diopter adjustment system 50. In this embodiment, multiple convex lenses are disposed within the housing 20 along the optical path of the optical diopter adjustment system 50 near the light-emitting side. Specifically, a first convex lens 57 is disposed between the first reflecting mirror 51 and the second reflecting mirror 52, and a second convex lens 58 is disposed between the second reflecting mirror 52 and the third reflecting mirror 53. The convex lenses can converge and process light, thus converging and magnifying the image, shortening the optical path for diopter adjustment, and making diopter adjustment more sensitive.
