[0024] The following description provides specific application scenarios and requirements of this specification, with the purpose of enabling those skilled in the art to make and use the contents of this specification. Various local modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but to the widest scope consistent with the claims.

[0025] The terms used herein are only used for the purpose of describing specific example embodiments and are not restrictive. For example, unless the context clearly indicates otherwise, as used herein, the singular forms "a", "an" and "the" may also include plural forms. When used in this specification, the terms "include", "comprise" and / or "contain" mean that the associated integers, steps, operations, elements and / or components exist, but do not exclude the existence of one or more other features, integers, steps, operations, elements, components and / or groups or that other features, integers, steps, operations, elements, components and / or groups may be added in the system / method.

[0026] In the present application, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. That is, X may include only any combination of A, B, and C, or may include any combination of A, B, and C and other possible contents / elements at the same time. The any combination of A, B, and C may be A, B, C, AB, AC, BC, or ABC.

[0027] In this application, unless explicitly stated otherwise, the association relationship between structures can be a direct association relationship or an indirect association relationship. For example, when describing "A is connected to B", unless it is explicitly stated that A is directly connected to B, it should be understood that A can be directly connected to B or indirectly connected to B; for another example, when describing "A is above B", unless it is explicitly stated that A is directly above B (AB is adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements and A is above B). And so on.

[0028] These and other features of the specification, as well as the operation and function of the related elements of the structure, and the economy of the combination and manufacture of the parts can be significantly improved in view of the following description. The description also includes all figures and text in the present specification with reference to the drawings, all of which form a part of the present specification. However, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0029] A laser measuring device is a device that uses lasers to accurately measure the distance to a target. It is widely used in scenes such as golf courses and outdoor exploration. The laser measuring device can be any type of laser measuring device. For example, the laser measuring device can be a laser measuring device that uses a pulse measurement method to measure. When working, it emits a beam or a series of short pulsed laser beams to the target, and receives the laser beam reflected by the target. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target. For another example, the laser measuring device can also be a laser measuring device that uses a phase measurement method to measure, and measures by detecting the phase difference between the emitted light and the reflected light when they propagate in space. This specification does not limit the type of laser measuring device.

[0030] The laser measuring device can be applied to a variety of usage scenarios, for example, in sports such as golf and archery, the distance between the athlete and the target can be quickly determined to assist in decision-making. For example, in the manufacturing industry, the position change of the workpiece and the distance measurement in the dynamic process can be monitored. For example, in interior design and decoration, it helps designers and decorators to quickly and accurately measure the size of the room, and so on. It can be understood that the laser measuring device of the present application can measure the length of a single target object in multiple scenarios, and can also measure the distance between the user and the target object, which is not limited here. For the purpose of demonstration, the following description in this application takes the measurement of the distance between the user and the target object on a golf course as an example.

[0031] Figure 1AA schematic structural diagram of a laser measuring device 001 provided according to some exemplary embodiments of the present application at a first viewing angle is shown; Figure 1B FIG. 1 shows a schematic structural diagram of a laser measuring device 001 provided according to some exemplary embodiments of the present application at a second viewing angle. Figure 1A and Figure 1B As shown, the present specification provides a laser measuring device 001. The laser measuring device 001 may include a housing 200, a laser measuring assembly 400, a telescope assembly 500, and a diopter adjustment assembly 700.

[0032] The housing 200 may be a mounting base of the laser measuring device 001. Other components of the laser measuring device 001 (such as the laser measuring component 400, the telescope component 500, and the diopter adjustment component 700) may be mounted with the housing 200 as a carrier. The shape of the housing 200 may be any shape to accommodate the installation of other components. The shape of the housing 200 may be an ergonomic shape to facilitate the use of the user. The material of the housing 200 may be any material, such as metal, plastic, polymer, rubber, and the like. This specification does not limit the shape and material of the housing 200. The housing 200 may include a first end 210 and a second end 220. The first end 210 and the second end 220 are respectively ends of the housing 200. Specifically, the first end 210 and the second end 220 may be two ends of the housing 200 distributed along the laser emission direction. The first end 210 may be the laser emission end of the laser measuring device 001. The second end 220 may be arranged opposite to the first end 210.

[0033] The laser measurement component 400 may be a part of the laser measurement device 001 for distance measurement and slope measurement. The laser measurement component 400 may be installed in the housing 200. When the laser measurement component 400 performs distance measurement, the laser measurement component 400 emits a laser to the outside of the housing 200. The laser is reflected back after encountering a target object. The laser reflected back by the target object is received by the laser measurement component 400. The laser measurement component 400 determines the distance between the target object and the laser measurement component 400 by comparing the emitted laser with the received laser. The laser measurement component 400 may include a laser transmitter ( Figure 1A and Figure 1B not shown) and a laser receiver ( Figure 1A and Figure 1B (not shown in the figure) The laser transmitter can emit laser light passing through the first end 210. The laser receiver can receive the laser light passing through the first end 210 reflected back by the target object. Figure 1A The arrow 1 shown in the figure may be the emission direction of the laser, and the arrow 2 may be the receiving direction of the laser.

[0034] The telescope assembly 500 can be installed inside the housing 200. The telescope assembly 500 can be used to observe distant objects. In particular, when the laser measuring device 001 is used in a golf distance measurement scenario, since the golf course is large, the telescope assembly 500 can be used to magnify the target object in the distance to achieve observation, magnification and resolution of the target object. The telescope assembly 500 can include an objective lens part 510 and an eyepiece part 520. The objective lens part 510 can be installed at the first end 210. The objective lens part 510 is composed of a series of lenses and is located at one end close to the object to magnify the target object. The eyepiece part 520 is composed of a series of lenses and is located at one end close to the human eye. The eyepiece part 520 is installed at the second end 220 and is connected to the second end 220 in a movable manner along the optical axis direction of the eyepiece part 520. That is, the eyepiece portion 520 can move relative to the shell 200 along the optical axis direction of the eyepiece portion 520 to adjust the position of the focus of the eyepiece portion 520, thereby adjusting the refractive power of the eyepiece portion 520 to adapt to the vision of the human eye, so that eyes with different vision can obtain clear visual imaging.

[0035] The diopter adjustment range of the eyepiece portion 520 varies depending on the specific usage scenario. For example, when monitoring the position change of a workpiece in the manufacturing industry, the diopter adjustment range of the eyepiece portion 520 can be between -20D and +20D. For example, when measuring the distance between an athlete and a target in a golf course, the diopter adjustment range of the eyepiece portion 520 can be between -10D and +10D. For another example, when measuring the size of a room in interior design and decoration, the diopter adjustment range of the eyepiece portion 520 can be between -5D and +5D, and so on. In actual application, the diopter adjustment range of the eyepiece portion 520 can be set according to the specific usage scenario, which is not limited here.

[0036] The diopter adjustment assembly 700 is mounted on the second end 220. The diopter adjustment assembly 700 can be movably connected to the eyepiece portion 520 to adjust the position of the eyepiece portion 520 relative to the housing 200 in the optical axis direction. The specific structure of the movably connected assembly will be described in detail in the following description.

[0037] Figure 2 FIG. 1 shows a schematic diagram of an exploded structure of a laser measuring device 001 provided according to some exemplary embodiments of the present application. Figure 2As shown, the housing 200 may include an inner housing 270 and an outer housing 250. Both the inner housing 270 and the outer housing 250 are wall-type parts. The inner housing 270 may be a mounting base for the laser measurement assembly 400 and the telescope assembly 500. The laser measurement assembly 400 and the telescope assembly 500 may be mounted in the accommodating cavity formed by the inner housing 270. The outer housing 250 may be fixedly connected to the inner housing 270 and cover the outside of the inner housing 270. The inner housing 270 and the outer housing 250 are fixedly connected. There are many ways to achieve fixed connection, such as integral molding, threaded connection, welding, riveting, bonding, snap connection, mortise and tenon connection, etc., which are not limited in this specification. As mentioned above, the housing 200 may include a first end 210 and a second end 220. The first end 210 may be the end of the outer housing 250 or the end of the inner housing 270. The second end 220 may be the end of the outer housing 250 or the end of the inner housing 270.

[0038] The eyepiece portion 520 can be movably connected to the second end 220 of the inner shell 270 along the optical axis direction of the eyepiece portion 270, thereby realizing the movably connected eyepiece portion 520 relative to the shell 200 along the optical axis direction of the eyepiece portion 520.

[0039] The housing 200 further includes an end cap 290. The end cap 290 is disposed at the second end 220 and covers the diopter adjustment assembly 700. Specifically, the end cap 290 may cover the side of the diopter adjustment assembly 700 facing the outside of the housing 200 (i.e., facing the human eye). The end cap 290 may also cover the side of the eyepiece portion 520 facing the outside of the housing 200 (i.e., facing the human eye). The end cap 290 may be mounted on the outer housing 250 or on the inner housing 270. Figure 2 As shown, we will take the fixed connection between the end cover 290 and the outer shell 250 as an example for description. The fixed connection between the end cover 290 and the outer shell 250 includes but is not limited to integral molding, threaded connection, bonding, riveting, welding, bayonet connection, mortise and tenon connection, etc. Figure 2 The end cap 290 is fixedly connected to the outer shell 250 by a snap-fit ​​connection. An observation hole 291 may be provided on the end cap 290. The user may view the eyepiece portion 520 through the observation hole 291. The material of the end cap 290 may be any material, such as metal, plastic, silicone, etc. In order to improve comfort, the material of the end cap 290 may be a soft material, such as silicone, rubber, etc.

[0040] like Figure 2As shown, the diopter adjustment assembly 700 may include an adjustment knob 720. The adjustment knob 720 may be rotatably connected to the second end 220. For example, the adjustment knob 720 may be rotatably connected to the second end 220 of the inner housing 270, or may be rotatably connected to the second end 220 of the outer housing 250. For the convenience of demonstration, in the following description, we will take the adjustment knob 720 as an example of being rotatably connected to the second end 220 of the inner housing 270. The adjustment knob 720 may also be spirally connected to the eyepiece portion 520 along the optical axis direction of the eyepiece portion 520. Since the eyepiece portion 520 is spirally connected to the adjustment knob 720 along the optical axis direction of the eyepiece portion 520, the adjustment knob 720 may drive the eyepiece portion 520 to move spirally relative to the adjustment knob 720. At this time, the spiral movement of the eyepiece portion 520 relative to the adjustment knob 720 may be divided into a rotation relative to the circumferential direction of the adjustment knob 720 and a movement relative to the axial direction (i.e., the optical axis direction) of the adjustment knob 720. At the same time, since the eyepiece part 520 is connected to the housing 200 in a movable manner along the optical axis, the eyepiece part 520 cannot rotate relative to the housing 200. Therefore, when the adjusting knob 720 is turned, the adjusting knob 720 can drive the eyepiece part 520 to move along the optical axis. Therefore, the user does not need to adjust the diopter directly by adjusting the eyepiece part 520, and the eyepiece part 520 does not need to be exposed to the outside of the housing 200. During the observation process, observation is made through the eyepiece part 520, and the adjusting knob 720 is independently provided from the eyepiece part 520, so the adjusting knob 720 will not be operated by mistake, thereby providing a better experience for the user.

[0041] The diopter adjustment assembly 700 may further include an axial stopper 740. The axial stopper 740 may be used to axially position the adjustment knob 720 to prevent the adjustment knob 720 from moving in the axial direction relative to the second end 220 of the inner housing 270.

[0042] Figure 3 FIG. 2 shows a schematic diagram of the structure of the second end 220 of the inner housing 270 and the eyepiece portion 520 provided according to some exemplary embodiments of the present application. Figure 3As shown, the second end 220 of the inner housing 270 may include a connecting shaft 271. The connecting shaft 271 may be used to be installed with the adjusting knob 720. A positioning platform 275 may be provided at one end of the connecting shaft 271. The positioning platform 275 may prevent the adjusting knob 720 from moving along the optical axis direction of the eyepiece portion 520 when rotating. The positioning platform 275 may be provided at one end of the connecting shaft 271 close to the inner side of the housing 200. The positioning platform 275 protrudes in the radial direction of the connecting shaft 271 relative to the connecting shaft 271. When the adjusting knob 720 is installed with the connecting shaft 271, the positioning platform 275 may abut against one side of the adjusting knob 720 (for example, the side of the adjusting knob 720 facing the inside of the housing 200), and the axial stopper 740 may abut against the other side of the adjusting knob 720 (for example, the side of the adjusting knob 720 facing the outside of the housing 200), so that the adjusting knob 720 is axially fixed relative to the connecting shaft 271. The axial limiting member 740 may be fixedly connected to the connecting shaft 271 by threads, or may be connected by a slot, etc.

[0043] An eyepiece hole 273 may be provided on the second end 220 of the inner housing 270. Specifically, the eyepiece hole 273 may be provided on the connecting shaft 271. The eyepiece hole 273 may be used to install the eyepiece portion 520. The eyepiece hole 273 and the eyepiece portion 520 are adapted. The adaptation may be the adaptation of the size and shape of the eyepiece hole 273 and the eyepiece portion 520. For example, the eyepiece hole 273 and the eyepiece portion 520 are both cylindrical.

[0044] In some embodiments, a movable groove 277 may be provided on the connecting shaft 271. The movable groove 277 may be arranged on the eyepiece hole 273. The movable groove 277 penetrates the side wall of the connecting shaft 271 along the radial direction of the connecting shaft 271. At the same time, the movable groove 277 extends along the optical axis direction of the eyepiece portion 520. The movable groove 277 can be used to be connected to the eyepiece portion 520 along the optical axis direction of the eyepiece portion 520. The number of movable grooves 277 can be one or more, such as 2, 3, 4, 5, etc. Multiple movable grooves 277 can be evenly or unevenly distributed along the circumferential direction of the connecting shaft 271. Each movable groove 277 includes a first limiting portion 277-1 and a second limiting portion 277-3. The first limiting portion 277-1 and the second limiting portion 277-3 are respectively the ends of the movable groove 277 in the extension direction. The eyepiece portion 520 can move between the first limiting portion 277 - 1 and the second limiting portion 277 - 3 relative to the inner housing 270 .

[0045] The eyepiece portion 520 is provided with a guide post 521. The guide post 521 protrudes in the radial direction of the eyepiece portion 520. When the eyepiece portion 520 is mounted on the inner housing 270, the guide post 521 can be used to connect with the movable groove 277. The guide post 521 can pass through the movable groove 277 and be slidably connected with the movable groove 277, so as to realize that the eyepiece portion 520 is movable and connected relative to the inner housing 270 along the optical axis direction of the eyepiece portion 520. When the guide post 521 moves along the optical axis direction of the eyepiece portion 520, the guide post 521 moves between the first limit portion 277-1 and the second limit portion 277-3. The height of the guide post 521 can be greater than the thickness of the side wall of the connecting shaft 271. When the eyepiece portion 520 is mounted on the inner housing 270, the guide post 521 passes through the movable groove 277 and protrudes in the radial direction relative to the connecting shaft 271. It should be noted that the guide post 521 can be detachably connected to the eyepiece portion 520. The number of the guide posts 521 may be one or more, such as 2, 3, 4, 5, etc. It should be noted that the number of the guide posts 521 is the same as the number of the moving slots 277 .

[0046] Figure 4 The schematic diagram of the structure of an adjusting knob 720 provided according to some exemplary embodiments of the present application is shown. In some embodiments, the adjusting knob 720 may include a rotating connection portion 722. In some embodiments, the adjusting knob 720 may also include a dial button 724.

[0047] As mentioned above, the adjusting knob 720 is rotatably connected to the second end 220 of the inner housing 270, and the spiral connection with the eyepiece portion 520 can be realized by the rotating connecting portion 722. The rotating connecting portion 722 can be rotatably connected to the connecting shaft 271 of the inner housing 270. The rotating connecting portion 722 can include a connecting hole 722-1. The connecting shaft 271 is rotatably connected to the connecting hole 722-1. The positioning platform 275 and the axial positioning member 740 respectively abut against the two sides of the rotating connecting portion 722, so that the rotating connecting portion 722 is axially fixed relative to the connecting shaft 271.

[0048] The rotating connection part 722 is provided with a guide groove 722-3. The guide groove 722-3 extends in a spiral direction in the circumferential direction of the rotating connection part 722. The extension in the spiral direction may be extending in the circumferential direction along the surface of the rotating connection part 722 while being offset in the axial direction. The extension in the spiral direction may be a linear extension in the spiral direction or a nonlinear extension in the spiral direction. The guide groove 722-3 may penetrate the side wall of the rotating connection part 722 in the radial direction of the rotating connection part 722. The guide groove 722-3 may be used to be spirally connected with the eyepiece part 520 in the optical axis direction of the eyepiece part 520. Specifically, the eyepiece part 520 may be slidably connected with the rotating connection part 722 along the guide groove 722-3. The guide post 521 of the eyepiece part 520 may pass through the guide groove 722-3 to realize the sliding connection between the eyepiece part 520 and the adjustment knob 720 along the guide groove 722-3. The guide groove 722-3 includes a third limiting portion 722-31 and a fourth limiting portion 722-33. The third limiting portion 722-31 and the fourth limiting portion 722-33 are respectively the ends of the guide groove 722-3 in the extension direction. When the eyepiece portion 520 moves along the optical axis direction of the eyepiece portion 520 relative to the housing 200, the guide post 521 can move between the third limiting portion 722-31 and the fourth limiting portion 722-33. When the guide post 521 abuts against the first limiting portion 277-1 or the second limiting portion 277-3, the guide post 521 is located between the third limiting portion 722-31 and the fourth limiting portion 722-33. The number of the guide grooves 722-3 can be one or more, such as 2, 3, 4, 5, etc. It should be noted that the number of the guide grooves 722-3 is the same as the number of the guide posts 521.

[0049] Since the guide groove 722-3 extends in a spiral direction on the circumference of the rotating connection part 722, the rotating connection part 722 can drive the eyepiece part 520 to move in a spiral direction relative to the rotating connection part 722. At this time, the spiral movement of the eyepiece part 520 relative to the rotating connection part 722 can be divided into a rotation relative to the circumferential direction of the rotating connection part 722 and a movement relative to the axial direction (i.e., the optical axis direction) of the rotating connection part 722. At the same time, since the eyepiece part 520 is connected to the moving groove 277 along the optical axis direction, the eyepiece part 520 cannot rotate relative to the housing 200. Therefore, when the rotating connection part 722 is rotated, the rotating connection part 722 can drive the eyepiece part 520 to move in the optical axis direction. Therefore, the user does not need to directly adjust the diopter by adjusting the eyepiece part 520, and the eyepiece part 520 does not need to be exposed outside the housing 200. During the observation process, observation is made through the eyepiece portion 520, and the adjustment knob 720 is independently provided from the eyepiece portion 520, so the adjustment knob 720 will not be operated accidentally, thereby providing a better experience for the user.

[0050] In order to further prevent the user from accidentally touching the adjustment knob 720, the rotating connection part 722 may be covered by the housing 200. The rotating connection part 722 may be located between the inner housing 270 and the outer housing 250. The end cap 290 may cover the side of the rotating connection part 722 facing the outside of the housing 200. At this time, the adjustment knob 720 may also include a dial button 724. The dial button 724 may be arranged on the rotating connection part 722. The dial button 724 may pass through the housing 200 and be exposed to the outside of the housing 200. The user may drive the rotating connection part 722 to rotate by dialing the dial button 724. The dial button 724 may be fixedly connected to the rotating connection part 722. The fixed connection method includes but is not limited to integral molding, threaded connection, bonding, riveting, welding, bayonet connection, mortise and tenon connection, and the like. In some embodiments, the dial button 724 may be arranged in the radial direction of the rotating connection part 722. In the working state of the laser measuring device 001, the dial button 724 may be located below the rotating connection part 722. It should be noted that the working state of the laser measuring device 001 may be the use posture of the laser measuring device 001 when in use. In some embodiments, the dial button 724 may also be arranged in the axial direction of the rotating connection portion 722 .

[0051] Figure 5 FIG. 2 shows a schematic structural diagram of the connection between an inner housing 270, an eyepiece portion 520, and an adjustment knob 720 provided according to some exemplary embodiments of the present application. Figure 5 As shown, the guide column 521 of the eyepiece part 520 can pass through the movable groove 277 and the guide groove 722-3, so as to realize the movable connection between the eyepiece part 520 and the inner shell 270 along the optical axis direction, and the sliding connection between the eyepiece part 520 and the adjustment knob 720 along the guide groove 722-3 direction.

[0052] When the dial knob 724 is turned, the adjusting knob 720 rotates relative to the inner housing 270 around the optical axis direction of the eyepiece portion 520, thereby driving the guide post 521 to move between the third limit portion 722-31 and the fourth limit portion 722-33. Since the guide post 521 passes through the moving slot 277, the guide post 521 moves between the third limit portion 722-31 and the fourth limit portion 722-33 and moves between the first limit portion 277-1 and the second limit portion 277-3 along the optical axis direction. At the same time, since the guide post 521 is arranged on the eyepiece portion 520, when the guide post 521 moves along the optical axis direction, the eyepiece portion 520 also moves along the optical axis direction, thereby achieving diopter adjustment.

[0053] Figure 6 A front view of a laser measuring device 001 provided according to some exemplary embodiments of the present application is shown; Figure 7 Shows Figure 6 Section view along section BB. Figure 6 and Figure 7 As shown, a recessed portion 252 is provided on the outer surface of the second end 220 of the outer shell 250. The recessed direction of the recessed portion 252 is the optical axis direction of the eyepiece portion 520. In the working state of the laser measuring device 001, the recessed portion 252 is located below the adjusting knob 720. The working state is as described above and will not be described in detail here.

[0054] The outer shell 250 is provided with a notch 254 between the recessed portion 252 and the adjusting knob 720. The dial button 724 can pass through the notch 254 and be located in the recessed portion 252. At this time, the design of the recessed portion 252 can further improve the possibility that the dial button 724 is not accidentally touched.

[0055] In summary, this specification provides a laser measurement device 001, in which an adjustment knob 720 is separately provided. When the user turns the adjustment knob 720, the adjustment knob 720 rotates relative to the housing 200 around the optical axis. Since the eyepiece portion 520 and the adjustment knob 720 are slidably connected along the guide groove 722-3, the adjustment knob 720 can drive the eyepiece portion 520 to slide along the guide groove 722-3. Since the guide groove 722-3 extends along the circumferential spiral of the adjustment knob 720, the sliding of the eyepiece portion 520 relative to the adjustment knob 720 in the guide groove 722-3 can be divided into a circumferential direction and an axial direction (i.e., the optical axis direction). At the same time, since the eyepiece portion 520 is movably connected to the housing 200 along the optical axis direction. Therefore, when the adjustment knob 720 is turned, the adjustment knob 720 can drive the eyepiece portion 520 to move along the optical axis direction. Therefore, the user does not need to adjust the diopter directly by adjusting the eyepiece part 520, and the eyepiece part 520 does not need to be exposed outside the housing 200. During observation, observation is made through the eyepiece part 520, and the adjustment knob 720 is independently provided from the eyepiece part 520, so the adjustment knob 720 will not be operated by mistake, thereby providing a better experience for the user.
