Description

Technical Field

[0001] This invention relates to the field of optoelectronic technology, and more particularly to aiming aids and optical sights. Background Technology

[0002] An optical sight consists of a barrel, an objective lens at the front of the barrel, and an eyepiece at the rear. The area behind the eyepiece forms a viewing zone. When the human eye is placed within this viewing zone, it can capture light passing through the objective and eyepiece, forming an image within the eyeball. Additionally, the outer wall of the barrel is typically equipped with three radially protruding adjustment knobs (upper, left, and right knobs) for adjusting the reticle, correcting ballistic deviations, and adjusting the scope's focal length. To expand its functionality, the scope barrel often incorporates or integrates a rangefinder. To avoid mechanical interference from these adjustment knobs, the rangefinder must be mounted beyond the highest point of the adjustment knobs. This results in an excessive distance between its detection ray and the optical sight's barrel axis. This excessive distance increases ranging errors and also increases the size of the optical sight, affecting its portability. Summary of the Invention

[0003] In view of this, the present invention provides an aiming aid device to solve the problems of aiming aid devices in the prior art.

[0004] To achieve one, some, or all of the above objectives, or other objectives, the present invention proposes:

[0005] A aiming aid device, mounted on an optical sight, the optical sight comprising a scope barrel and multiple adjustment knobs protruding from the outer wall of the scope barrel, with a gap region formed between any two adjacent adjustment knobs, allowing external light to pass through the scope barrel; the device includes:

[0006] The detection mechanism is capable of emitting detection rays to obtain measurement information, and the detection rays pass through the gap region.

[0007] A display, used to emit display light containing the measurement information,

[0008] A light-directing lens assembly is used to reflect the display light, and external light can pass through the light-directing lens assembly.

[0009] In some embodiments, a housing is further included, which is detachably connected to the lens barrel. The housing is used to house the display, the light-directing lens assembly, and the detection mechanism. The housing includes a first housing cavity and a second housing cavity that communicate with each other. The first housing cavity includes an opposing observation port and a connection port. The connection port is used to connect the lens barrel. The light-directing lens assembly is disposed in the first housing cavity and / or the second housing cavity, and the display is disposed in the second housing cavity.

[0010] In some embodiments, the light-directing lens assembly includes a steering mirror, which is obliquely disposed within the first receiving cavity and between the observation port and the connection port. The steering mirror is used to reflect the display light so that the display light passes through the observation port, and the steering mirror allows external light passing through the lens barrel to pass through.

[0011] In some embodiments, the second receiving cavity includes a first mounting end and a second mounting end that are spaced apart from each other, the second mounting end being close to and communicating with the first receiving cavity; the display is fixed to the first mounting end.

[0012] The light-directing lens assembly also includes a total reflection mirror, which is tilted at the second mounting end, and the display light is reflected by the total reflection mirror onto the deflecting mirror.

[0013] In some embodiments, the detection mechanism includes a transmitter and a receiver, the transmitter emitting detection rays and the receiver receiving reflected light from the detection rays.

[0014] The reflected light from the detection ray passes through the gap region and then strikes the receiver;

[0015] Alternatively, the reflected light from the detection ray passes through the lens barrel and is then reflected by the light-deflecting lens assembly toward the receiver.

[0016] In some embodiments, the system further includes a housing, the housing comprising a first receiving cavity and a third receiving cavity; the first receiving cavity is used to receive a portion of the light-directing lens assembly, and the first receiving cavity is used to connect the lens barrel;

[0017] The third receiving cavity at least partially coincides with the gap region in the axial projection of the lens barrel, and both the transmitter and the receiver are disposed within the third receiving cavity.

[0018] In some embodiments, the system further includes a housing, the housing comprising a first receiving cavity and a third receiving cavity; the first receiving cavity is used to receive a portion of the light-directing lens assembly, and the first receiving cavity is used to connect the lens barrel;

[0019] The third receiving cavity at least partially coincides with the gap region in the axial projection of the lens barrel, the transmitter is disposed in the third receiving cavity, and the receiver is disposed in the first receiving cavity.

[0020] In some embodiments, a coupling lens group is further included, located between the display and the light-directing lens group, for adjusting the image sharpness of the display;

[0021] The coupling lens assembly has a sleeve extending through both ends and at least one spherical lens disposed within the sleeve; the sleeve is movable, and moving the sleeve can change the distance between the spherical lens and the display.

[0022] In some embodiments, the coupling lens assembly further includes a mounting sleeve with a threaded hole. The sleeve includes a threaded portion and an adjusting portion. The threaded portion is threadedly connected to the threaded hole, and the adjusting portion allows the sleeve to rotate.

[0023] In some embodiments, the adjusting part includes a toothed groove on the outer wall of the sleeve; the device further includes an adjusting rod rotatably mounted on the housing, the adjusting rod including a gear end and a handwheel end, the gear end being placed in the second receiving cavity and meshing with the toothed groove; the handwheel end being placed outside the housing.

[0024] In some embodiments, the outer wall of the housing is provided with a receiving groove for receiving the handwheel end.

[0025] In some embodiments, the housing further includes a mounting tube and a connecting plate extending radially along the mounting tube. The mounting tube is disposed inside the housing, and the first receiving cavity is disposed inside the mounting tube. The inner wall of the mounting tube is provided with an inclined slot, and the steering mirror is inserted into the slot. The connecting plate extends to the second mounting end of the second receiving cavity and is used to fix the total reflection mirror.

[0026] In some embodiments, the housing further includes a third receiving cavity with an opening at its front end, the detection mechanism being installed within the third receiving cavity, and the detection ray passing through the opening.

[0027] In some embodiments, the detection mechanism includes a detection body and a leveling component;

[0028] The detection body includes a detection ball head at its front end and an adjustment tail at its rear end. The detection ball head is placed at the opening of the third receiving cavity and emits the detection rays.

[0029] The leveling assembly is installed at the end of the third receiving cavity away from the opening, and the parallelism between the detection ray and the aiming center line of the optical sight can be changed by the leveling assembly.

[0030] In some embodiments, the adjusting tail includes a first force-bearing surface and a second force-bearing surface that are at an angle to each other, and the leveling component includes:

[0031] At least two leveling knobs, one of which is rotatably mounted on the wall of the third receiving cavity and abuts against the first force-bearing surface, and the other of which is rotatably mounted on the wall of the third receiving cavity and abuts against the second force-bearing surface;

[0032] An elastic support is used to elastically connect the adjusting tail and the inner wall of the third receiving cavity. The elastic force of the elastic support causes the first force-bearing surface and the second force-bearing surface to abut against their corresponding leveling knobs.

[0033] In some embodiments, the first force-bearing surface intersects with the second force-bearing surface and forms a vertical angle, and the elastic force direction of the elastic support coincides with the angle bisector of the vertical angle.

[0034] In some embodiments, the leveling knob includes a fine-tuning portion exposed outside the third receiving cavity and a spherical portion placed inside the third receiving cavity. The spherical portion is used to abut against the first force-bearing surface or the second force-bearing surface. By rotating the fine-tuning portion, the spherical portion can be made to press against the first force-bearing surface or the second force-bearing surface.

[0035] In some embodiments, the leveling assembly further includes a fine-tuning rod for controlling the rotation of the fine-tuning part, and the housing is also provided with a receiving socket, in which the fine-tuning rod can be received.

[0036] The present invention also proposes an optical sight, including the aforementioned aiming aid device.

[0037] Implementing the embodiments of the present invention will have the following beneficial effects:

[0038] After adopting the aforementioned aiming assistance device, when the device is installed on an optical sight, the projection of the detection mechanism in the circumferential direction coincides with the gap area, allowing its detection ray to pass through the gap area. Furthermore, the distance between the detection ray and the axis of the scope barrel is less than the minimum distance between the adjusting handwheel and the axis of the scope barrel. This results in the detection mechanism's radial protrusion from the outer wall of the scope barrel being less than the adjusting handwheel's radial protrusion from the outer wall of the scope barrel, effectively reducing the radial outward protrusion of the detection mechanism within the scope barrel. This reduces the overall size of the optical sight equipped with the device, making it easier for users to carry. The smaller distance between the detection ray and the axis of the scope barrel further reduces the error in the measurement information acquired by the detection mechanism, improving the measurement accuracy of the detection mechanism.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects and not to describe a particular order.

[0068] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0069] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0070] See appendix Figure 1 - Appendix Figure 14 This invention proposes an aiming assistance device, which is installed on an optical sight. The optical sight includes a scope barrel 9 and multiple adjustment handwheels 90 protruding from the outer wall of the scope barrel 9, with a gap region 900 formed between any two adjacent adjustment handwheels 90. For ease of explanation, the structure of the optical sight is further described as follows: Figures 1-3As shown, the front end of the scope tube 9 is provided with an objective lens 91, and the rear end of the scope tube 9 is provided with an eyepiece 92. That is, the front end of the scope tube 9 faces the object, and the rear end of the scope tube 9 is close to the human eye. External light L1 enters the scope tube 9 through the objective lens 91 and finally passes through the eyepiece 92. The optical sight is generally provided with three adjustment handwheels 90, namely the upper handwheel 901, the left handwheel 902 and the right handwheel 903. The gap area 900 can be formed between the upper handwheel 901 and the left handwheel 902, or between the upper handwheel 901 and the right handwheel 903.

[0071] Based on the structure of the optical sight described above, such as Figures 1-7 As shown, the aiming aid includes: a detection mechanism 2, a display 3, and a light-directing lens group 4; the detection mechanism 2 is able to emit a detection ray L2 to obtain measurement information, and the detection ray L2 passes through the gap region 900; the display 3 is used to emit a display ray L4 containing measurement information, the light-directing lens group 4 is used to reflect the display ray L4, and the external light L1 can pass through the light-directing lens group 4.

[0072] Specifically, the detection mechanism 2 is roughly cylindrical, with its axis parallel to the axis of the lens tube 9, and the axis passes through the gap region 900. The axis of the detection mechanism 2 roughly coincides with the emitted detection ray L2.

[0073] In some embodiments, the distance D1 between the detection ray L2 and the axis L3 of the scope barrel is less than the maximum distance D2 between the adjusting handwheel 90 and the axis L3 of the scope barrel. This makes the height of the detection mechanism 2 protruding from the scope barrel 9 less than the maximum height of the adjusting handwheel 90 protruding from the scope barrel 9 after the device is mounted on the optical sight, thus making the structure more compact and smaller in size. It also makes the detection ray L2 closer to the axis L3 of the scope barrel, so that the measurement information obtained by the detection mechanism 2 is more consistent with the true information of the object seen inside the scope barrel 9. More preferably, the distance D1 between the detection ray L2 and the axis L3 of the scope barrel can be set to be less than the minimum distance D3 between the adjusting handwheel 90 and the axis L3 of the scope barrel. In this case, the height of the detection mechanism 2 protruding from the scope barrel 9 is less than the minimum height of the adjusting handwheel 90 protruding from the scope barrel 9, further making the structure of the device more compact and smaller in size. It should also be noted that the distance between the adjusting handwheel 90 and the axis L3 of the microscope tube specifically refers to the distance between the far end of the adjusting handwheel 90 protruding from the microscope tube 9 and the axis L3 of the microscope tube; in addition, apart from the above restrictions, the distance D1 between the detection ray L2 and the axis L3 of the microscope tube also needs to be greater than the maximum outer diameter of the microscope tube 9 (such as the outer diameter at the objective lens 91), so as to prevent the detection ray L2 from being blocked by the outer wall of the microscope tube 9 at the objective lens 91.

[0074] For optical sights of different specifications or sizes, the gap region 900 has different limitations, as illustrated by the upper handwheel 901 and the left handwheel 902; for example, in some embodiments, the gap region 900 can also be defined as follows: Figure 1 The open region shown has radial boundaries formed by rays from the contour lines of the left handwheel 902 and the upper handwheel 901, respectively. This open region has no circumferential boundary. In some embodiments, the gap region 900 can also be defined as follows: Figure 13 The closed fan-shaped region shown is such that the radius of the gap region 900 is equal to the size of the upper handwheel 901 or the left handwheel 902 protruding from the outer wall of the lens barrel 9. Specifically, the size of the left handwheel 902 with the smaller protrusion can be selected as the radius of the gap region 900. In short, the gap region 900 described in this invention is not limited to a specific geometric shape. Its essence is the area between two adjacent adjustment handwheels 90 that allows the detection ray L2 to pass through without obstruction. The range of this area is dynamically determined by the actual contour and relative position of the adjustment handwheels 90.

[0075] Specifically, the detection mechanism 2 is electrically connected to the display 3 so that the measurement information acquired by the detection mechanism 2 can be sent to the display 3. The display 3 emits a display light L4 containing the measurement information toward the light-directing lens group 4. The light-directing lens group 4 is usually provided with at least one reflective lens for reflecting the display light L4. The light-directing lens group 4 is also provided with a transmissive lens or a hollow area that allows external light L1 to pass through. When the aiming aid is installed on an optical sight, the transmissive lens or hollow area of ​​the light-directing lens group 4 is located at the rear end of the lens barrel 9. By placing the human eye behind the transmissive lens or hollow area of ​​the light-directing lens group 4, the external light L1 passing through the light-directing lens group 4 and the reflected display light L4 can be obtained, and then imaged in the human eye as an image of the distant target and an image containing measurement information obtained through the lens barrel 9. The detection mechanism 2 is generally an infrared rangefinder, which acquires measurement information by emitting and receiving corresponding detection rays L2, so that the measurement information includes at least the distance between the user and the target object obtained by the infrared rangefinder. It should also be noted that various sensors can be installed on the device so that the measurement information also includes wind speed, temperature, humidity, etc. When the device is installed at the rear end of the scope barrel 9, the projection of the detection mechanism 2 along the axial direction of the scope barrel 9 coincides with the gap region 900, allowing its detection ray L2 to pass through the gap region 900. Furthermore, the distance between the detection ray L2 and the axis L3 of the scope barrel is less than the maximum distance between the adjusting handwheel 90 and the axis L3 of the scope barrel. This results in the radial protrusion height of the detection mechanism 2 from the outer wall of the scope barrel 9 being less than the radial protrusion height of the adjusting handwheel 90 from the outer wall of the scope barrel 9, effectively reducing the radial outward protrusion dimension of the detection mechanism 2 in the scope barrel 9. This reduces the overall size of the optical sight equipped with the device, making it easier for users to carry. When an optical sight equipped with this device is applied to a firearm, its small overall size lowers the overall center of gravity, which helps improve the shooting stability of the firearm. Furthermore, the smaller distance between the detection ray L2 and the axis L3 of the scope barrel further reduces the error in the measurement information acquired by the detection mechanism 2, thus improving the measurement accuracy of the detection mechanism 2. By using the light-directing lens group 4 to fuse the display ray L4 containing the measurement information and the external ray L1 of the distant target acquired by the optical sight, the image of the optical sight and the image containing the measurement information can be displayed on the same screen, reducing the ranging process and improving ranging efficiency.

[0076] In addition, the detection mechanism 2 is arranged at intervals along the axial direction of the lens barrel 9 and the adjustment handwheel 90, and the detection mechanism 2 is distributed at the end of the lens barrel 9 where the eyepiece 92 is provided, so as to facilitate user operation; in other embodiments, when the detection rays of the detection mechanism 2 are not blocked by the adjustment handwheel 90, the detection mechanism 2 can also be distributed at any position along the axial direction of the lens barrel 9.

[0077] Reference Figure 6In some embodiments, the aiming aid further includes a housing 5, which is detachably connected to the lens barrel 9. The housing 5 is used to house the display 3, the light-directing lens assembly 4, and the detection mechanism 2. Specifically, multiple chambers can be provided inside the housing 5 to install and fix the display 3, the light-directing lens assembly 4, and the detection mechanism 2, making the overall structure of the device compact. The all-around coverage of the housing 5 seals the internal structure, providing dust and water resistance. Figure 5 The device also includes an outer ring 8. Multiple L-shaped slots 50 are provided on the outer circumferential wall of the front end of the outer casing 5. Multiple locking protrusions 80 that mate with the L-shaped slots 50 are provided on the inner wall of the outer ring 8. The outer ring 8 is connected to the outer casing 5 via the locking protrusions 80 and the L-shaped slots 50. A locking bolt 81 is also provided on the outer ring 8. When the outer ring 8 is fitted onto the rear end of the lens barrel 9, the locking bolt 81 locks the outer ring 8 onto the outer wall of the lens barrel 9, thereby installing the outer casing 5 onto the rear end of the lens barrel 9. Adapter tubes of different sizes can also be provided at the rear ends of the outer ring 8 and the lens barrel 9 to accommodate eyepieces of various sizes in different lens barrels 9. In other embodiments, the outer casing 5 and the outer ring 8 can be integrally formed.

[0078] Reference Figure 7 and Figure 8In some embodiments, the housing 5 includes a first receiving cavity 51 and a second receiving cavity 52 that are interconnected. The first receiving cavity 51 includes an observation port 511 and a connection port 510. The observation port 511 allows the user to acquire the fused image within the first receiving cavity 51. The connection port 510 is used to connect the lens barrel 9. The light-directing lens assembly 4 is disposed within the first receiving cavity 51 and / or the second receiving cavity 52. ​​The display 3 is disposed within the second receiving cavity 52. ​​Specifically, the first receiving cavity 51 is coaxially distributed at the rear end of the lens barrel 9, and its connection port 510 is close to the eyepiece 92 of the lens barrel 9. The observation port 511 allows the user to observe and acquire the corresponding image, so that external light L1 passes sequentially through the objective lens 91, the lens barrel 9 body, and the eyepiece 92. The system comprises a mirror 92, a first receiving cavity 51, and an observation port 511. The user places their eye at the observation port 511 to receive external light L1, ultimately forming an image within the eye. It should be noted that during use, the user should place their eye behind the observation port 511 and maintain a certain distance to prevent the observation port 511 from impacting the eye due to external forces. The display 3 is generally fixed to the end of the second receiving cavity 52 furthest from the first receiving cavity 51. The light-directing lens group 4 is distributed within the first receiving cavity 51 or simultaneously within both the first and second receiving cavities 51 and 52. For example, when the length direction of the first receiving cavity 51 is approximately parallel to or at an angle to the length direction of the lens barrel 9... A small angle is formed; in other words, the length direction of the first receiving cavity 51 is approximately perpendicular to the length direction (axial direction) of the lens barrel 9, and the length direction of the second receiving cavity 52 is approximately parallel to the length direction (axial direction) of the lens barrel 9. The first receiving cavity 51 and the second receiving cavity 52 are approximately L-shaped bent cavities. The second receiving cavity 52 is distributed along the axial direction of the lens barrel 9 and is located behind the upper handwheel 901, so that the display light L4 emitted by the display 3 is approximately parallel to or at a small angle to the external light L1 passing through the lens barrel 9. The light-directing lens assembly 4 includes at least two lenses, wherein a reflective lens that can reflect the display light L4 is provided at the end of the second receiving cavity 52 away from the display 3. The internal structure includes mirrors such as a semi-reflective mirror, beam splitter, and prism that do not block the external light L1 passing through the lens barrel 9. These mirrors can also reflect the display light L4 after it has been reflected by the mirrors in the second receiving cavity 52. ​​This allows the display light L4 to pass through the observation port 511 after being reflected by two mirrors. The external light L1 passing through the lens barrel 9 is not blocked by the mirrors in the light-directing lens group 4 located in the first receiving cavity 51 and passes through the observation port 511. This allows the user to simultaneously obtain the display light L4 and the external light L1. This arrangement makes the radial outward bulge of the second receiving cavity 52 on the outer wall of the lens barrel 9 smaller, thus reducing the overall size of the device and making it easier to carry. This makes it easier to carry the device or an optical sight with the device installed.In other embodiments, when the length directions of the first receiving cavity 51 and the second receiving cavity 52 are approximately perpendicular to or form a large angle with the length direction of the lens barrel 9, in other words, the first receiving cavity 51 and the second receiving cavity 52 are approximately radially parallel straight cylindrical cavities, the display light L4 emitted by the display 3 forms a certain angle with the external light L1 passing through the lens barrel 9. The light-directing lens assembly 4 includes at least one lens, which specifically adopts a semi-reflective mirror, beam splitter, prism, or other lens that allows the external light L1 passing through the lens barrel 9 to pass through. It can also reflect the display light L4 emitted by the display 3. At this time, the display light L4 reaches the first receiving cavity 51 after passing through the second receiving cavity 52, and is reflected by the lens of the light-directing lens group 4 and passes through the observation port 511. Meanwhile, the external light L1 passing through the lens barrel 9 is not blocked by the lens of the light-directing lens group 4 set in the first receiving cavity 51 and passes through the observation port 511. This allows the user to obtain the display light L4 and the external light L1 at the same time. This layout uses fewer reflective lenses to reflect the display light L4 to the observation port 511, which is more cost-effective.

[0079] Reference Figure 7 and Figure 8 In some embodiments, the light-directing lens assembly 4 includes a steering mirror 40, which is obliquely disposed within the first receiving cavity 51. The steering mirror 40 is located between the observation port 511 and the connection port 510. The steering mirror 40 is used to reflect the display light L4, allowing the display light L4 to pass through the observation port 511, and also allows external light L1 passing through the lens barrel 9 to pass through. Specifically, the steering mirror 40 can be a semi-reflective mirror, a beam splitter, or a prism, so that the steering mirror 40 can reflect the display light L4 without blocking the external light L1. Specifically, the steering mirror 40 obliquely divides the first receiving cavity 51 in half, and the space formed by the steering mirror 40 and the observation port 511 allows the display light L4 to enter, so that the display light L4 can be reflected by the steering mirror 40 to the observation port 511. During use, the display light L4 emitted by the display 3 is directed towards the steering mirror 40 and is reflected by the steering mirror. The external light L1, reflected by the scope barrel 9, is directed towards and passes through the steering mirror 40, causing the display light L4 containing measurement information and the external light L1 containing target image information to merge at the steering mirror 40. This achieves the fusion of the optical sight image and the measurement information image, allowing the user to see the optical sight image through the observation port 511 while simultaneously viewing measurement information such as distance from the target, wind speed, temperature, and humidity, as well as auxiliary information from functional modules such as ballistics, level, and angle. In other embodiments, the area of ​​the steering mirror 40 can be designed to be smaller, so that it cannot completely separate the first receiving cavity 51. In this case, the steering mirror 40 is used to reflect the display light L4, while the portion of the first receiving cavity 51 without the steering mirror 40 is hollowed out, allowing the external light L1 passing through the scope barrel 9 to pass through and ultimately reach the observation port 511.

[0080] Reference Figure 7 In some embodiments, the second receiving cavity 52 includes a first mounting end 521 and a second mounting end 522 that are far apart from each other, with the second mounting end 522 close to and communicating with the first receiving cavity 51; the display 3 is fixed to the first mounting end 521; specifically, the second receiving cavity 52 is an elongated cylindrical chamber, with the first mounting end 521 and the second mounting end 522 being the two ends in the length direction of the second receiving cavity 52, and the length direction of the second receiving cavity 52 being approximately parallel to the axis L3 of the lens barrel, such as... Figure 7 As shown, the first receiving cavity 51 and the second receiving cavity 52 are roughly L-shaped cavities. When the device is installed at the rear end of the lens barrel 9, the second receiving cavity 52 is located behind the upper handwheel 901. By making reasonable use of the axial free space of the lens barrel 9, the radial outward convexity of the second receiving cavity 52 on the outer wall of the lens barrel 9 is smaller, which significantly reduces the volume of the device. Based on the above structure, the light-directing lens assembly 4 also includes a total reflection mirror 41. The total reflection mirror 41 is tilted and mounted on the second mounting end 522. The display light L4 is reflected by the total reflection mirror 41 onto the turning mirror 40. Specifically, the total reflection mirror 41 and the turning mirror 40 are tilted relative to each other so that the display light L4 is reflected by the total reflection mirror 41 onto the turning mirror 40. Due to the axial distribution of the second receiving cavity 52, the display light L4 of the display 3 is directed axially toward the total reflection mirror 41 on the second mounting end 522, so that the reflected display light L4 is directed toward the turning mirror 40 and finally reflected by the turning mirror 40 to the observation port 511. Through the total reflection mirror 41 and the turning mirror 40, the display light L4 emitted by the display 3 and the external light L1 passing through the lens barrel 9 are both directed toward the observation port 511, so that the user's eye can simultaneously obtain the display light L4 and the external light L1, and simultaneously obtain the image of the distant target including the optical sight and the measurement information.

[0081] To facilitate the installation of the total reflection mirror 41 and the steering mirror 40 into the interior of the housing 5, the housing 5 also includes a mounting tube 5a and a connecting plate 5b extending radially along the mounting tube 5a, such as... Figure 8 and Figure 9The mounting tube 5a is located inside the housing 5, the first receiving cavity 51 is located inside the mounting tube 5a, the inner wall of the mounting tube 5a is provided with an inclined slot 5a1, the steering mirror 40 is inserted into the slot 5a1, the connecting plate 5b extends to the second mounting end 522 of the second receiving cavity 52, and the connecting plate 5b is used to fix the total reflection mirror 41. Specifically, the two ends of the mounting tube 5a pass through to form a connection port 510 and an observation port 511 of the first receiving cavity 51, respectively. The connection port 510 is used to connect the lens barrel 9. In addition, the side wall of the mounting tube 5a is also provided with a communication port 512 connecting to the second receiving cavity 52, so that the display light L4 reflected by the total reflection mirror 41 can enter the first receiving cavity 51 through the communication port 512. The connecting plate 5b is provided with an inclined mounting surface, and the total reflection mirror 41 is fixed on the inclined mounting surface. In actual production, the total reflection mirror 41 is installed on the inclined mounting surface, the steering mirror 40 is installed in the slot 5a1, and finally the mounting tube 5a with the connecting plate 5b is placed inside the outer casing 5. It should be noted that, in order to ensure that the display light L4 incident on the total reflection mirror 41 can be reflected on the steering mirror 40, the tilt angle of the slot 5a1 and the tilt angle of the inclined mounting surface on the connecting plate 5b can be the same or different. To ensure that the internal components of the housing 5 are not contaminated by dust and rain, a full lens 5100 can be installed at the connection port 510 to seal the connection port 510 without obstructing the passage of external light L1 through the lens barrel 9. An observation lens 5110 can be installed at the observation port 511 to seal the observation port 510 without obstructing the user from obtaining external light L1 and display light L4.

[0082] Reference Figure 6 and Figure 7 In some embodiments, the aiming aid further includes a coupling lens group 6, which is located between the display 3 and the light-directing lens group 4, and is used to adjust the imaging clarity of the display 3. Specifically, the coupling lens group 6 is composed of multiple spherical lenses. By changing the distance between the coupling lens group 6 and the display 3, the refractive power of the display light L4 is adjusted, so that users with different vision can obtain a clear picture containing measurement information when using it.

[0083] Reference Figure 6 and Figure 7The coupling lens assembly 6 includes a mounting cylinder 60, a sleeve 61 extending through both ends, and at least one spherical lens 62 disposed within the sleeve 61. The mounting cylinder 60 is fixed within the second receiving cavity 52, the sleeve 61 is movably disposed, and the at least one spherical lens 62 is positioned between the display 3 and the total reflection mirror 41. Moving the sleeve 61 changes the distance between the spherical lens 62 and the display 3. Specifically, the display light L4 emitted by the display 3 passes through at least one spherical lens 62 and is reflected by the total reflection mirror 41 onto the steering mirror 40, and finally reflected by the steering mirror 40 to the observation port 511. The image clarity in the human eye can be changed by adjusting the distance between the refractive lens 62 and the display 3. Multiple refractive lenses 62 can also be installed inside the sleeve 61. These lenses have a uniform focal plane. Placing them inside the sleeve 61 avoids direct contact between the lenses and external adjustment structures, preventing contamination. By moving the sleeve 61, the distance between the multiple lenses 62 and the display 3 is changed, thereby altering the clarity of the image containing measurement information in the human eye, making it suitable for users with different visual acuity. In other embodiments, at least one refractive lens 62 can be positioned between the display 3 and the turning mirror 40. When the length direction of the second receiving cavity 52 is approximately perpendicular to the length direction of the lens barrel 9, the display light L4 emitted by the display 3 can directly strike the turning mirror 40. In this case, the total reflection mirror 41 is not required. The display light L4 emitted by the display 3 passes through at least one refractive lens 62 and directly strikes the turning mirror 40, finally being reflected by the turning mirror 40 to the observation port 511.

[0084] To improve the stability of the sleeve 61 during rotation, in some embodiments, the mounting sleeve 60 is provided with a threaded hole 600. The sleeve 61 includes a threaded portion 610 and an adjusting portion 611. The threaded portion 610 is threadedly connected to the threaded hole 600. The adjusting portion 611 allows the sleeve 61 to rotate. The axial displacement of the sleeve 61 is achieved through the threaded connection. The threaded connection has stronger structural stability and can more accurately adjust the distance between the refractory lens 62 and the display 3. In other embodiments, a worm gear or other rotational displacement structure can also be used. In other embodiments, a notch can be made in the outer shell 5 to expose part of the adjusting portion 611. The user can contact and move the adjusting portion 611 to make the sleeve 61 rotate, thereby changing the distance between the refractory lens 62 and the display 3. In other embodiments, the sleeve 61 is slidably disposed within the second receiving cavity 52. ​​The outer wall of the sleeve 61 is square so that it can only slide axially relative to the second receiving cavity 52. ​​A threaded hole is provided on the sleeve 61, and a screw is installed on the outer shell 5. One end of the screw enters the second receiving cavity 52 and is threadedly connected to the threaded hole of the sleeve 61. By controlling the other end of the screw exposed in the second receiving cavity 52, the sleeve 61 can slide in a direction away from or towards the display 3, thereby changing the distance between the refracting spherical lens 62 and the display 3.

[0085] Reference Figure 5 and Figure 6 In some embodiments, the adjustment part 611 includes a toothed groove 6110 on the outer wall of the sleeve 61; the aiming auxiliary device also includes an adjustment rod 72, which is rotatably mounted on the housing 5. The adjustment rod 72 includes a gear end 720 and a handwheel end 721. The gear end 720 is placed in the second receiving cavity 52 and meshes with the toothed groove 6110; the handwheel end 721 is placed outside the housing 5. Specifically, multiple toothed grooves 6110 are provided and distributed on the outer wall of the sleeve 61. The gear end 720 meshes with the toothed groove 6110 to drive the transmission, so that when the user controls the rotation of the sleeve 61 through the handwheel end 721, the sleeve 61 can be prevented from rotating significantly, thus achieving fine and stable control of the sleeve 61.

[0086] Furthermore, a receiving groove 55 for accommodating the handwheel end 721 can be provided on the outer wall of the housing 5. The handwheel end 721 protrudes at least partially from the receiving groove 55, making it convenient for the user to contact and operate the handwheel end 721. The receiving groove 55 also reduces the outward protrusion of the handwheel end 721, which on the one hand reduces the probability of the handwheel end 721 being hit by other objects, and on the other hand reduces the overall size of the device, making its structure more compact. It should also be noted that in other embodiments, the outer wall of the handwheel end 721 is not protruding from the receiving groove 55, ensuring that the user's fingertip can contact the outer wall of the handwheel end 721 through the receiving groove 55 to operate the handwheel end 721.

[0087] Reference Figure 5 and Figure 6 In some embodiments, at least one positioning ball head 550 is provided on the inner wall of the receiving groove 55, and at least one positioning groove 7210 that can cooperate with the positioning ball head 550 is provided on the axial end wall of the handwheel end 721. Specifically, there are two positioning ball heads 550 and two positioning grooves 7210. When the distance between the refracting spherical lens 62 and the display 3 is the factory default distance, the two positioning ball heads 550 and the two positioning grooves 7210 are locked together to improve the stability of the adjusting rod 72 on the housing 5 and prevent the adjusting rod 72 from shaking or wobbling randomly. When the handwheel end 721 is turned, the positioning ball head 550 can rotate out from the positioning groove 7210 and abut against the inner wall of the receiving groove 55 to form a transition fit, making the rotation of the adjusting rod 72 more stable.

[0088] Reference Figure 5In some embodiments, a sealing ring 73 is provided at the connection between the adjusting rod 72 and the housing 5. The sealing ring 73 can prevent external dust and rainwater from entering the second receiving cavity 52 through the connection gap between the adjusting rod 72 and the housing 5, thus avoiding contamination of the internal display 3 and the refracting spherical lens 62. In addition, it can also make the second receiving cavity 52 form a closed and opaque dark room so that the display light L4 is not interfered with by external light sources, thereby improving the clarity of the final image.

[0089] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the aiming aid further includes an observation element 1, which includes an observation tube 11. One end of the observation tube 11 is connected to the observation port 511, and the other end is away from the outer casing 5. The observation tube 11 is generally conical in shape, with the smaller end connected to the observation port 511 and the larger end used for human eye observation. The observation tube 11 can help the user block the remaining light at the human eye, reduce light interference to the user, and improve the user's visibility. When in use, the user places their eye in the visible area of ​​the observation tube 11, and can simultaneously obtain the display light L4 and the external light L1 passing through the lens tube 9, and then image it in the human eye as an image containing measurement information and a distant target image obtained through the lens tube 9.

[0090] Reference Figure 6 In some embodiments, the housing 5 further includes a third receiving cavity 53, the front end of which is provided with an opening 530. The detection mechanism 2 is installed in the third receiving cavity 53, and the detection ray L2 can pass through the opening 530. Specifically, the third receiving cavity 53 is located beside the second receiving cavity 52. ​​The axial projection of the third receiving cavity 53 coincides with the gap region 900, so that the detection ray L2 emitted by the detection mechanism 2 installed therein can pass through the gap region 900 without being blocked by the adjustment handwheel 90. The third receiving cavity 53 is provided with a first wire passage hole 531 at a position away from its opening 530. The first wire passage hole 531 connects the second receiving cavity 52 and the third receiving cavity 53, so that the wires used to connect the various components inside the housing 5 can be distributed between the second receiving cavity 52 and the third receiving cavity 53 through the first wire passage hole 531, so as to facilitate the transmission of the measurement information of the detection mechanism 2 to the display 3. It should also be noted that there is no clear boundary between the first receiving cavity 51, the second receiving cavity 52 and the third receiving cavity 53. In other embodiments, any two or three of the first receiving cavity 51, the second receiving cavity 52 and the third receiving cavity 53 can be completely connected to form two or one receiving space that can accommodate various components.

[0091] Reference Figure 3 , Figure 5 , Figure 13 and Figure 14The detection mechanism 2 includes a transmitter 22 and a receiver 23. The transmitter 22 is located inside the third receiving cavity 53 and emits a detection ray L2 through an opening 530. The receiver 23 is used to receive the reflected light L2' of the detection ray L2. Specifically, the detection mechanism 2 can be an infrared rangefinder. The detection ray L2 emitted by the transmitter 22 is an infrared ray, and the receiver 23 is a sensor capable of receiving the corresponding infrared ray. The transmitter 22 emits the detection ray L2 towards the target object. The detection ray L2 is reflected by the target object, and the reflected light L2' of the detection ray L2 is directed to the receiver 23. After being processed by the detection mechanism 2, the measurement information is transmitted to the display 3.

[0092] Reference Figure 3 , Figure 5 , Figure 13 and Figure 14 The receiver 23 can receive the reflected light L2' of the detection ray L2 by being set at different positions.

[0093] like Figure 3 , Figure 5 , Figure 13 As shown, in some embodiments, the receiver 23 is located in the third receiving cavity 53. Since the third receiving cavity 53 is located behind the gap region 900, the detection ray L2 emitted by the transmitter 22 passes through the gap region 900 and is directed toward the target object, while the reflected ray L2' of the detection ray L2 passes through the gap region 900 and is directed toward the receiver 23. This method is advantageous for integrating the receiver 23 and the transmitter 22 into a single cavity, which facilitates production and maintenance.

[0094] like Figure 14As shown, in some embodiments, the receiver 23 is disposed in the first receiving cavity 51. The reflected light L2' of the detection ray L2 passes through the lens barrel 9 and is reflected by the turning mirror 40 and directed towards the receiver 23. Specifically, the receiver 23 is disposed between the connection port 510 and the turning mirror 40, and the receiving port of the receiver 23 faces the turning mirror 40, so that the receiver 23 can receive the reflected light L2' of the detection ray L2 reflected by the turning mirror 40. Specifically, the reflected light L2' of the detection ray L2 is received by the objective lens 91 on the lens barrel 9 along with the external light L1. The external light L1 passes through the turning mirror 40 and is directed towards the observation port 511. The reflected light L2' of ray L2 is reflected by the deflecting mirror 40 into the receiver 23. The reflected light L2' of ray L2 is invisible and can be reflected by the deflecting mirror 40. With the help of the larger-diameter objective lens 91 on the optical sight, the receiver 23, located in the first receiving cavity 51, can more stably receive the reflected light L2' of ray L2. Furthermore, because the objective lens 91 has a larger diameter and a greater amount of light intake, it further enhances the receiver 23's ability to receive the reflected light L2' of ray L2, enabling distance measurement of more distant targets. The large-diameter objective lens 91 can also further improve… The high-range-measuring mechanism 2 has improved environmental interference resistance during target object measurement. In summary, compared to the small-aperture receiving objective lens on a traditional rangefinder, the receiver 23 in this embodiment relies on the large-aperture objective lens 91 of the optical sight to receive the reflected light L2' of the detection ray L2, greatly improving the ranging capability of the detection mechanism 2. It should also be noted that the reflected light L2' of the detection ray L2 and the external light L1 are actually coaxial and overlapped, and are received together by the objective lens 91 on the lens barrel 9 and enter the interior of the lens barrel 9. The receiver 23 includes a lens group composed of 0 to multiple lenses and a ranging laser sensor. The ranging laser sensor is connected to the lens barrel 9. The distance measurement information to the target object is obtained by receiving the reflected light L2' of the detection ray L2, and finally transmitted to the display 3, which emits the display light L4 containing the measurement information. In other embodiments, when the receiver 23 is located in the first receiving cavity 51, one or more reflective mirrors can be arranged between the receiver 23 and the steering mirror 40. Through the reflection of multiple reflective mirrors, the installation position of the receiver 23 and the opening orientation of the receiver 23 can be selected according to actual needs. In addition, by separating the receiver 23 from the transmitter 22, the volume of the third receiving cavity 53 can be reduced, thus making the size of the device smaller.

[0095] Reference Figure 6In some embodiments, the aiming aid further includes a power supply unit 71, and the housing 5 further includes a fourth receiving cavity 54. The power supply unit 71 is installed in the fourth receiving cavity 54 and is electrically connected to the detection mechanism 2 and the display 3. Specifically, the fourth receiving cavity 54 is provided with a second wire hole 540 communicating with the third receiving cavity 53, so that the wires of the power supply unit 71 are connected to the detection mechanism 2 through the second wire hole 540, and are also connected to the display 3 through the second wire hole 540, the third receiving cavity 53, the first wire hole 531, and the second receiving cavity 52, thereby providing power to the detection mechanism 2 and the display 3. Figure 6 As shown, the power supply unit 71 can specifically be a cylindrical energy storage battery. The length direction of the fourth receiving cavity 54 is approximately parallel to the length direction of the third receiving cavity 53, and it is distributed in the radial extension direction of the third receiving cavity 53 and away from the lens barrel 9. In other embodiments, the fourth receiving cavity 54 can also be distributed between the second receiving cavity 52 and the upper handwheel 901 to make full use of the axial space of the lens barrel 9. The power supply unit 71 can also be externally connected to any position on the outer wall of the housing 5 or set at any position on the outer wall of the lens barrel 9. It should also be noted that the power supply unit 71 can also wirelessly transmit power to the components inside the housing 5.

[0096] like Figure 4 An operation button 30 can also be provided on the outer wall of the mounting housing. The operation button 30 is electrically connected to the display 3 via a ribbon cable. The operation button 30 can control the measurement information displayed on the display 3. Specifically, the operation button 30 can be located on the outer side near the second mounting end 522, so that the operation button 30 faces the user when in use, making it convenient for the user to operate. A ribbon cable can be provided to connect the operation button 30 and the display 3. The ribbon cable can be set to fit against the inner wall of the second receiving cavity 52, thereby avoiding interference of the ribbon cable with the display light L4. It should also be noted that a main control board can be installed at the operation button 30. This main control board distributes power from the power supply group 71 to the detection mechanism 2 and the display 3. The main control board integrates Bluetooth, enabling the aiming auxiliary device to connect with mobile terminals such as smartphones, transmitting measurement information to the mobile terminal. Conversely, information from the mobile terminal can also be sent to the main control board via this communication method, allowing the measurement information to include information sent from the mobile terminal, enriching the final measurement information display. The main control board can also integrate or connect functional sensors such as temperature and humidity sensors and gravity sensors, displaying the information acquired by these sensors on the display 3 and transmitting it to the user's eye via the light-directing lens group 4. Furthermore, the detection mechanism 2 and the main control board can also use wireless connections such as Bluetooth for data transmission.

[0097] Reference Figure 6 , Figure 11 , Figure 12 In some embodiments, the detection mechanism 2 includes a detection body 20 and a leveling component 21. The detection body 20 includes a detection ball head 200 at its front end and an adjustment tail 201 at its rear end. The detection ball head 200 is positioned at the opening 530 of the third receiving cavity 53 and emits a detection ray L2. The leveling component 21 is installed at the end of the third receiving cavity 53 away from the opening 530. The leveling component 21 can change the parallelism between the detection ray L2 and the aiming center line of the optical sight. It should be noted that the optical sight often needs to adjust the reticle inside by adjusting the handwheel 90 to change the angle of the aiming center line. Therefore, it is necessary to keep the detection ray L2 emitted by the detection body 20 parallel to the aiming center line of the optical sight to reduce the measurement error of the detection body 20 and improve the measurement accuracy. The detection body 20 can be specifically selected as an infrared rangefinder. The detection ball head 200 is installed at the front end of the third receiving cavity 53, and the detection ray L2 can pass through the opening 530. The adjustment tail 201 is positioned at the... At the rear end of the third receiving cavity 53, the detection ball head 200 and the adjustment tail 201 are connected by a connecting bracket plate, on which a corresponding detection circuit board is provided. During the installation of the detection body 20 into the third receiving cavity 53, there may be installation errors, causing the detection ray L2 to deviate from the aiming center line of the optical sight. Alternatively, the device may be slightly misaligned due to bumps or knocks during use, causing the detection body 20 to deviate from the aiming center line of the optical sight. To avoid such parallel deviations, a leveling component 21 is installed on the outer shell 5. The leveling component 21 is partially exposed and partially placed inside the third receiving cavity 53 and connected to the adjustment tail 201. By changing the radial position of the adjustment tail 201, the detection ball head 200 is radially displaced, thereby reducing the parallel error between the detection ray L2 and the aiming center line of the optical sight, ensuring that the detection ray L2 and the aiming center line of the optical sight remain parallel, thus ensuring that the measurement information obtained by the detection body 20 is more accurate.

[0098] Reference Figure 11In some embodiments, the adjusting tail 201 includes a first force-bearing surface 2011 and a second force-bearing surface 2012 that are at an angle to each other. The leveling assembly 21 includes at least two leveling knobs 210 and an elastic support member 211. One leveling knob 210 is rotatably mounted on the cavity wall of the third receiving cavity 53 and abuts against the first force-bearing surface 2011. The other leveling knob 210 is rotatably mounted on the cavity wall of the third receiving cavity 53 and abuts against the second force-bearing surface 2012. The elastic support member 211 is used to elastically connect the adjusting tail 201 and the inner wall of the third receiving cavity 53. The elastic force of the elastic support member 211 causes the first force-bearing surface 2011 and the second force-bearing surface 2012 to abut against their corresponding leveling knobs 210. Specifically, the leveling knob 210 is threaded onto the wall of the third receiving cavity 53; the adjusting tail 201 is a block-shaped structure, with the first force-bearing surface 2011 and the second force-bearing surface 2012 intersecting and forming a vertical angle α. The elastic force direction of the elastic support 211 coincides with the angle bisector L5 of the vertical angle α. In other words, the axial force of the two leveling knobs 210 and the elastic force of the elastic support 211 act on the adjusting tail 201 from three different directions, balancing the force points of the adjusting tail 201 in its circumferential direction. Specifically, one leveling knob 210 abuts against the first force-bearing surface 2011, and the other leveling knob 210 abuts against the second force-bearing surface 2012. A support surface 2010 is provided on the adjusting tail 201, and the elastic support 211 is installed on the support surface 2010, with the end of the elastic support 211 abutting against the inner wall of the third receiving cavity 53. During use, refer to... Figure 11 By rotating the leveling knob 210, which contacts the first force-bearing surface 2011, the adjusting tail 201 can be displaced in the Y-axis direction. By rotating the leveling knob 210, which contacts the second force-bearing surface 2012, the adjusting tail 201 can be displaced in the X-axis direction, thereby achieving the parallelism adjustment between the detection ray L2 and the aiming center line of the optical sight. Figure 11 and Figure 12The elastic support component 211 specifically includes a connecting pipe 2110 with external threads, a support rod 2111, and a support spring 2112. The adjusting tail 201 also includes stepped mounting holes 2013 distributed on the support surface 2010. One end of the support rod 2111 has a radially extending limiting platform 2111a, and the other end is used to abut against the inner wall of the third receiving cavity 53. During installation, the support spring 2112 is placed in the stepped mounting hole 2013, and the other end of the support rod 2111 is passed through the connecting pipe 2110. The connecting pipe 2110 is threaded into the stepped mounting hole 2013, so that one end of the supporting spring 2112 abuts against the inner wall of the stepped mounting hole 2013, and the other end abuts against the limiting platform 2111a. The supporting rod 2111 can move axially relative to the connecting pipe 2110. During use, when the leveling knob 210 presses the first force surface 2011 or the second force surface 2012, the supporting spring 2112 in the adjusting tail 201 is compressed, and the adjusting tail 201 moves in the corresponding direction relative to the supporting rod 2111.

[0099] Reference Figure 4 and Figure 6 In some embodiments, the leveling knob 210 includes a fine-tuning portion 2101 exposed outside the third receiving cavity 53 and a spherical portion 2100 placed inside the third receiving cavity 53. The spherical portion 2100 is used to abut against the first force-bearing surface 2011 or the second force-bearing surface 2012. By rotating the fine-tuning portion 2101, the spherical portion 2100 can press against the first force-bearing surface 2011 or the second force-bearing surface 2012. The spherical portion 2100 can reduce friction with the adjusting tail portion 201, reduce resistance, and reduce frictional loss. The exposed fine-tuning portion 2101 is convenient for the user to operate.

[0100] To facilitate the operation of the fine-tuning part 2101, the leveling assembly 21 also includes a fine-tuning rod 213 for controlling the rotation of the fine-tuning part 2101. The housing 5 is also provided with a receiving hole 56, in which the fine-tuning rod 213 can be received. Specifically, a slot can be provided on the fine-tuning part 2101, and the end of the fine-tuning rod 213 can be a slotted blade. In other embodiments, a cross slot can also be provided on the fine-tuning part 2101, and the end of the fine-tuning rod 213 can be a cross blade. Alternatively, the fine-tuning part 2101 can be a hexagonal nut, and the end of the fine-tuning rod 213 can be a hexagonal wrench.

[0101] It should also be noted that, referring to Figure 3 and Figure 12The detection mechanism 2 also includes a visible laser emitter 24, which emits a visible laser parallel to the detection ray L2 to assist in leveling. Specifically, since the detection ray L2 is invisible infrared light, the human eye cannot directly see the detection ray L2 when the detection body 20 is adjusted by the leveling component 21. Therefore, a visible laser emitter 24 that can emit a visible laser is provided. The visible laser emitter 24 and the emitter 22 that emits the detection ray L2 are fixed on the detection body 20. The visible laser and the detection ray L2 are kept parallel. Therefore, when adjusting using the leveling component 21, it is only necessary to make the visible laser parallel to the aiming center line of the optical sight.

[0102] In summary, in some embodiments, when the aiming aid device of the present invention is installed in a position other than that described above, even if it does not have a detection mechanism 2, its light-directing lens group 4 and coupling lens group 6 can still be used on various optical sights. In other words, the display 3 can acquire target information in other ways. The display 3 emits light containing target information, which is reflected by the light-directing lens group 4 and fused with the external light L1 passing through the scope barrel 9, ultimately allowing the user to simultaneously acquire the image of the scope barrel 9 and the measurement image of the display 3. In addition, besides using the coupling lens 6 to adjust the diopter of the display 3, the light-directing lens group 4 can also be combined with other methods to adjust the diopter of the display 3, such as directly changing the position of the display 3 to change the distance between the display 3 and the light-directing lens 4 to achieve diopter adjustment.
