[0054] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0055] The up and down direction in the present application is the vertical direction of the through-window viewing and aiming device, that is, the first direction; the left and right direction is the lateral direction of the through-window viewing and aiming device, that is, the second direction; the front and back direction is the longitudinal direction of the through-window viewing and aiming device, that is, the third direction and the optical path direction.

[0056] Reference below Figure 1-Figure 12 A through-window viewing device according to an embodiment of the present application is described.

[0057] like Figure 1 and Figure 4As shown, the through-window viewing and aiming device of the present application includes: a housing 1, a lens assembly 2 and a laser 3.

[0058] The lens group 2 includes an objective lens assembly 21 and an eyepiece assembly 22, which are arranged in sequence on the housing 1 along the optical path; the laser 3 includes a shell 31 and a emitting device 32, the shell 31 is provided with a plurality of heat dissipation holes 311, the shell 31 is installed outside the housing 1, and the emitting device 32 is arranged on the shell 31; wherein, one end of the eyepiece assembly 22 away from the objective lens assembly 21 is protruded relative to the end of the laser 3 along the optical path direction, and the angle between the emitting direction of the laser 3 and the optical path direction is less than or equal to 5°.

[0059] The laser 3 is a device that can emit laser light, which is a high-quality light source that can be used for supplementary light. The lens group 2 is an optical sight, and the lens group 2 and the laser 3 can cooperate to achieve day and night sighting functions.

[0060] When the surrounding environment is bright, the lens group 2 can work independently to aim at the target behind the window; when the surrounding environment is dark, the lens group 2 can cooperate with the laser 3, and the lens group 2 can aim at the target behind the window under the fill light of the laser 3 to improve the aiming accuracy.

[0061] The shell 31 of the laser 3 is connected to the housing 1 and protects the emitting device 32, which can emit lasers. The shell 31 is provided with a plurality of heat dissipation holes 311, which connect the environment inside the shell 31 with the outside to achieve effective heat dissipation through air circulation, so that the laser 3 can maintain a proper temperature when working for a long time, improve the working stability of the emitting device 32, and prevent overheating from affecting the performance.

[0062] One end of the eyepiece assembly 22 facing away from the objective lens assembly 21 is protruded relative to the end of the laser 3 along the optical path direction. In actual use, when the observer observes through the eyepiece assembly 22, the end of the laser 3 is spaced apart from the observer to prevent the observer from colliding with the end of the laser 3 during the observation process, thereby reducing interference to the observer during the observation process.

[0063] The position of the laser 3 relative to the housing 1 is adjustable, and the laser 3 can have a rotational freedom around an axis in a first direction and a rotational freedom around an axis in a second direction relative to the housing 1, and the first direction and the second direction are perpendicular to each other, so that the laser 3 can be adjusted in multiple directions in a three-dimensional space. By adjusting the position of the laser 3 and rotating around axes in different directions, the precise control of the laser beam can be improved, thereby improving the accuracy of the fill light.

[0064] The angle between the emission direction of the laser 3 and the direction of the optical path is less than or equal to 5°. The deviation angle between the emission direction of the laser 3 and the direction of the optical path of the lens group 2 is small, which can improve the stability of the laser 3 when adjusting the position and working. The laser beam deviates less from the direction of the optical path during transmission, and the laser 3 does not need to be adjusted at a large angle, which improves the aiming and observation accuracy of the laser 3 in cooperation with the lens group 2.

[0065] The lens assembly 2 and the laser 3 are both installed in the housing 1. The lens assembly 2 can be completely located in the housing 1 or partially located in the housing 1. The laser 3 is installed outside the housing 1, that is, the laser 3 and the lens assembly 2 are located in different working environments, and the laser 3 and the lens assembly 2 are spaced apart.

[0066] The laser 3 can be installed outside the housing 1 by a detachable connection method such as a snap connection, a plug connection or a threaded connection, so as to facilitate installation, use and disassembly and storage.

[0067] In the related art, in order to improve the integration and miniaturization of the device, the through-window aiming and viewing device with day and night aiming and viewing functions usually installs the aimer and the laser in the same installation space. On the one hand, the laser will generate a lot of heat during long-term operation, and overheating will affect the performance of the lens group. In addition, since the human body is in direct contact with the eyepiece assembly during the aiming and viewing process, the heat is directly transferred to the human body, reducing the user experience. On the other hand, since the emission path of the laser is close to the direction of the optical path, the scattered light generated by the laser beam will interfere with the imaging of the lens group and reduce the imaging clarity.

[0068] According to the through-window aiming device provided in the embodiment of the present application, by installing the laser 3 on the outside of the housing 1, the lens group 2 can be completely or partially located in the housing 1, so that the laser 3 and the lens group 2 are located in different working environments. The heat generated during the operation of the laser 3 will directly enter the external environment through the heat dissipation holes 311. On the one hand, the heat dissipation effect of the laser 3 can be improved, so that the laser 3 can maintain an appropriate temperature when working for a long time, improve the working stability of the emitting device 32, and prevent overheating from affecting the performance of the emitting device 32. At the same time, the influence of the heat of the laser 3 on the lens group 2 can be reduced, the working stability of the lens group 2 can be improved, and the overheating can be prevented from affecting the performance of the lens group 2; on the other hand, the laser 3 is spaced apart from the lens group 2, and there is a certain distance between the laser beam and the optical path, which can reduce the interference of the scattered light generated by the laser beam on the imaging of the lens group 2, thereby improving the imaging effect.

[0069] In some embodiments, Fig.11 As shown, the housing 1 is provided with a groove 13 in a first direction, the notch of the groove 13 faces the laser 3 , and at least a part of the laser 3 is installed in the groove 13 .

[0070] The housing 31 of the laser 3 can be detachably connected to the groove wall of the groove 13 by at least one of a snap connection, a plug-in connection and a pivot connection.

[0071] In this embodiment, by providing the groove 13, at least part of the laser 3 is installed in the groove 13, so that the size of the whole machine along the first direction can be reduced. The groove 13 provides an escape space for the laser 3 to compensate for the installation height of the laser 3.

[0072] In some embodiments, at least one of the two ends of the groove 13 along the second direction and the two ends along the third direction is open to facilitate installation of the laser 3 .

[0073] In some embodiments, Figure 2 and Figure 4 As shown, the laser 3 is detachably mounted on the top of the housing 1 along the first direction. Compared with the laser 3 being mounted on both sides along the second direction, the laser 3 is arranged at the top of the housing 1 to facilitate the adjustment of the emission angle of the laser 3 and reduce the impact on the observer's line of sight during observation.

[0074] In some embodiments, Figure 2 As shown, the through-window sighting device further includes a battery, which is disposed in the housing 1 and electrically connected to the laser 3. The battery is used to power the laser 3, thereby improving the portability of the entire device. The battery can be a common finished battery, and the battery can have multiple cells, and multiple cells are connected in series to enhance the endurance of the laser 3.

[0075] In some embodiments, Figure 3 As shown, the laser 3, the mirror assembly 2 and the battery are arranged in sequence along the first direction.

[0076] Among them, the first direction is perpendicular to the direction of the optical path. During use, the lens group 2 is located at the height of the observer's glasses to facilitate the observer to align with the eyepiece for observation; the battery is located between the lens group 2 and the shoulder rest, and the battery can raise the height of the lens group 2 to facilitate the observer to observe the lens group 2; the laser 3 is located above the lens group 2, which can reduce the impact of the laser 3 on the observer's line of sight during observation, and at the same time facilitate the observer to adjust the position of the laser 3.

[0077] In some embodiments, Fig.11 As shown, the bottom end of the housing 1 forms a battery compartment 14 with one end open, and the battery is installed in the battery compartment 14; the housing 1 also includes: a battery end cover 12, which is arranged at the open end of the battery compartment 14 and is used to close the battery compartment 14.

[0078] Among them, the battery compartment 14 is used to install batteries. One end of the battery compartment 14 is open to facilitate the insertion and removal of batteries. The battery compartment 14 has multiple battery installation positions, for example, 2, 3 or more positions can be set to facilitate the insertion of multiple batteries, thereby improving the endurance of the laser 3.

[0079] The battery end cover 12 is used to close the battery compartment 14 so that the battery can be stably electrically connected to the laser 3 during use of the through-window aiming device, thereby improving the working stability of the laser 3 and preventing the battery from falling off during use.

[0080] The battery end cover 12 may be connected to the open end of the battery compartment 14 by at least one of a pivot connection, a plug-in connection, a snap connection, and a threaded connection.

[0081] In some embodiments, Fig.12 As shown, the battery end cover 12 is provided with a first mounting hole 121, and the end of the housing 1 facing the battery end cover 12 is provided with a second mounting hole aligned with the first mounting hole 121; the housing 1 also includes: a locking member 15, the locking member 15 passes through the first mounting hole 121 and the second mounting hole in sequence to lock the battery end cover 12 and the battery compartment 14.

[0082] The locking member 15 is used to lock the battery end cover 12 and the battery compartment 14, so as to improve the sealing effect of the battery end cover 12 on the battery compartment 14 and reduce the risk of the battery end cover 12 falling off. The locking member 15 can be a connecting member such as a screw or a stud.

[0083] The first mounting hole 121 is a through hole, and the second mounting hole can be a blind hole or a through hole. The locking member 15 can be threadedly connected with the first mounting hole 121 and the second mounting hole, or the locking member 15 can be loosely matched with the first mounting hole 121 and threadedly matched with the second mounting hole.

[0084] In some embodiments, Fig.11 and Fig.12 As shown, the locking member 15 includes a locking portion 151 and a handle 152, the locking portion 151 passes through the first mounting hole 121 and the second mounting hole in sequence; the handle 152 is pivotally mounted on the locking portion 151, and the handle 152 has a first state perpendicular to the battery end cover 12 and a second state parallel to the battery end cover 12.

[0085] The locking portion 151 may be a connecting piece such as a screw or a stud, and the locking portion 151 may be threadedly connected with the first mounting hole 121 and the second mounting hole.

[0086] The handle 152 can rotate around the pivot axis relative to the locking portion 151. When the battery end cover 12 needs to be opened relative to the battery compartment 14, the handle 152 can be rotated around the pivot axis so that the handle 152 is perpendicular to the battery end cover 12 and is in the first state. The user can rotate the handle 152 around the axis of the locking portion 151 to remove the locking portion 151 from the second mounting hole, thereby releasing the connection between the battery end cover 12 and the battery compartment 14, so that the battery end cover 12 can be opened relative to the battery compartment 14, which is convenient and quick, without the need for manual labor. Other opening tools; after placing the battery end cover 12 at the open end of the battery compartment 14, the user can rotate the handle 152 in the opposite direction around the axis of the locking portion 151 to cooperate and connect the locking portion 151 with the second mounting hole, thereby locking the battery end cover 12 and the battery compartment 14. After the locking is completed, the user can rotate the handle 152 around the pivot axis so that the handle 152 is parallel to the battery end cover 12 and is in the second state, thereby reducing the protruding height of the handle 152 relative to the battery end cover 12 and improving the integration of the device.

[0087] In some embodiments, Fig.12 As shown, a limiting portion 1511 is provided at one end of the locking portion 151 away from the handle 152 , and the outer diameter of the limiting portion 1511 is greater than the inner diameter of the first mounting hole 121 .

[0088] Among them, the limiting portion 1511 protrudes from the surrounding wall of the locking portion 151, and the outer diameter of the limiting portion 1511 is larger than the inner diameter of the first mounting hole 121, and the outer diameter of the limiting portion 1511 is less than or equal to the inner diameter of the second mounting hole, thereby preventing the locking portion 151 from falling off from the first mounting hole 121 without affecting the threaded cooperation between the locking portion 151 and the second mounting hole.

[0089] The inner diameters of the first mounting hole 121 and the second mounting hole can be different. For example, the inner diameter of the second mounting hole is larger than the inner diameter of the first mounting hole 121. The limiting portion 1511 can be threadedly connected to the second mounting hole, and the other parts of the locking portion 151 except the limiting portion 1511 can be threadedly connected or clearance-fitted with the first mounting hole 121.

[0090] In some embodiments, the battery end cover 12 can be pivotally mounted on the open end of the battery compartment 14. After the locking portion 151 is released from the threaded connection with the second mounting hole, the battery end cover 12 can be flipped around the pivot axis, so that the battery end cover 12 can be opened or closed relative to the open end of the battery compartment 14, thereby improving the integrity of the device, reducing the risk of parts loss, and shortening the assembly time of the device.

The observer can easily fine-tune the position and emission direction of the laser 3 to adjust the incident angle of the laser beam and focus and position the laser beam, thereby meeting the fill light requirements of the target objects at different positions and improving the aiming accuracy of the through-window viewing and aiming device.

[0099] The first knob 61 is rotatably installed on the housing 1; the first slider 62 is slidably installed on the first slide 16 of the housing 1 along the second direction, and the first knob 61 abuts against the first slider 62; the second slider 63 is slidably installed on the second slide 17 of the housing 1 along the first direction, and the second slider 63 abuts against the first slider 62. The second slider 63 is suitable for abutting the laser 3 along the first direction, and the abutting position is spaced apart from the first rotating shaft 51.

[0100] The abutment position of the second slider 63 against the laser 3 is spaced apart from the first rotation axis 51 , so that the second slider 63 can use a smaller force to push the laser 3 to move through the lever principle, so that the second slider 63 can push the laser 3 to do a pitching motion around the first rotation axis 51 .

[0101] The observer can rotate the first knob 61 to move the first knob 61 in the second direction, thereby causing the first knob 61 to generate a thrust on the first slider 62, and the first knob 61 pushes the first slider 62 to slide in the second direction in the first slide 16; the second slider 63 abuts against the first slider 62, and the thrust borne by the first slider 62 is transmitted to the second slider 63, and the first slider 62 pushes the second slider 63 to slide in the second slide 17 along the first direction. When the second slider 63 abuts against the laser 3, the first slider 62 moves in the first direction to push the end of the laser 3 away from the first rotation axis 51 to perform a pitch motion around the first rotation axis 51.

[0102] like Figure 7 As shown, the working principle of the first adjusting member 6 is as follows: the observer rotates the first knob 61, and the first knob 61 generates a driving force on the first slider 62, so that the first slider 62 slides along the second direction. Since the first slider 62 abuts against the second slider 63, the sliding action of the first slider 62 is transmitted to the second slider 63, so that the second slider 63 slides along the first direction. The sliding of the second slider 63 along the first direction abuts against the laser 3, so as to achieve a pitching action of the laser 3 around the first rotation axis 51.

[0103] In this embodiment, by setting the first slider 62 to slide along the first slide 16 and the second slider 63 to slide along the second slide 17, the rotational movement of the first knob 61 can be converted into linear movement of the first slider 62 along the second direction and linear movement of the second slider 63 along the first direction.

[0104] The first slider 62 and the second slider 63 include at least the following two structures:

[0105] First, if Figure 7 As shown, the end faces where the first sliding block 62 and the second sliding block 63 abut are inclined surfaces, and the normal line of the inclined surface forms an acute angle with the first direction; the second sliding block 63 is a ball.

[0106] In this embodiment, the ball abuts against the inclined surface of the first slider 62. When the first slider 62 slides to the right along the first slide 16, the ball slides upward in the first direction along the extension direction of the inclined surface due to the limitation of the second slide 17. When the ball abuts against the laser 3 and the first knob 61 continues to rotate, the ball pushes the emitting end of the laser 3 to raise its head upward along the first direction.

[0107] Secondly, the end surface where the first slider 62 and the second slider 63 abut is an inclined surface, and the normal line of the inclined surface forms an acute angle with the first direction. The second slider 63 has an inclined surface parallel to the inclined surface of the first slider 62 .

[0108] In this embodiment, the two end surfaces of the first slider 62 and the second slider 63 are wedge-shaped. When the first slider 62 slides to the right along the first slide 16, the second slider 63 slides upward along the first direction along the extension direction of the inclined surface due to the limitation of the second slide 17. When the second slider 63 abuts against the laser 3 and the first knob 61 continues to rotate, the second slider 63 pushes the emitting end of the laser 3 to raise its head upward along the first direction.

[0109] In some embodiments, Figure 7 As shown, the first knob 61 includes: a connecting portion 611 and a rotating portion 612; the connecting portion 611 is connected to the housing 1, and the connecting portion 611 is provided with a cavity extending along the second direction, and the cavity is connected to the first slide 16; at least a portion of the rotating portion 612 is arranged in the cavity, and the side wall of the rotating portion 612 located in the cavity is threadedly connected to the inner wall of the cavity, and the inner end portion of the rotating portion 612 along the second direction is suitable for abutting against the first slider 62.

[0110] The connecting portion 611 and the rotating portion 612 cooperate with each other to realize the pushing effect of the first knob 61 on the first sliding block 62 .

[0111] The connecting portion 611 is connected to the housing 1, and the connecting portion 611 plays the role of fixing and supporting the entire first knob 61. A cavity extending along the second direction is provided inside the connecting portion 611, and the cavity not only provides an installation space for the rotating portion 612, but also communicates with the first slideway 16, so that the rotation of the first knob 61 can be transmitted to the first slider 62.

[0112] The connection portion 611 may be fixedly connected to the housing 1 by threaded connection, welding, plug-in connection or other connection methods.

[0113] At least part of the rotating part 612 is disposed inside the cavity of the connecting part 611 , and at least part of the rotating part 612 is located outside the cavity. An observer can operate the rotating part 612 outside the housing 1 without directly contacting the internal mechanical structure.

[0114] The side wall of the rotating part 612 located in the cavity is threadedly connected to the inner wall of the cavity. This design allows the rotating part 612 to rotate in the cavity. When the observer rotates the rotating part 612, the rotating motion is converted into linear motion along the second direction because the rotating part 612 is threadedly connected to the inner wall of the cavity. When the inner end of the rotating part 612 along the second direction abuts against the first slider 62, the linear motion of the rotating part 612 directly pushes the first slider 62, causing the first slider 62 to slide along the second direction.

[0115] In actual use, the observer rotates the rotating part 612 of the first knob 61. Due to the threaded connection between the rotating part 612 and the inner wall of the cavity, the rotational motion of the rotating part 612 is converted into linear motion along the second direction. This linear motion is transmitted to the first slider 62 through the inner end of the rotating part 612, and the inner end of the rotating part 612 pushes the first slider 62 to slide along the second direction. Since the first slider 62 abuts against the second slider 63, the sliding motion of the first slider 62 is further transmitted to the second slider 63, and finally the laser 3 is pitched around the first rotation axis 51, thereby realizing the up and down adjustment of the laser beam along the first direction.

[0116] In this embodiment, the rotating part 612 is threadedly connected to the connecting part 611, and the connecting part 611 is connected to the housing 1, so that the rotational motion of the rotating part 612 is converted into linear motion, so that the laser 3 can perform a pitch motion around the first rotating axis 51, thereby realizing the up and down adjustment of the laser beam along the first direction. At the same time, the setting of the purely mechanical structure improves the adjustment stability and durability of the first adjusting member 6.

[0117] In some embodiments, Figure 7As shown, the rotating portion 612 includes: a first rotating portion 6121, a second rotating portion 6122 and a third rotating portion 6123; at least a portion of the first rotating portion 6121 is rotatably mounted on the outer wall of the connecting portion 611, and the first rotating portion 6121 and the connecting portion 611 are loosely matched; the second rotating portion 6122 is connected to the first rotating portion 6121, and at least a portion of the second rotating portion 6122 is located in the cavity, and the second rotating portion 6122 is threadedly connected to the inner wall of the cavity; the outer end portion of the third rotating portion 6123 along the second direction is connected to the second rotating portion 6122, and the inner end portion abuts against the first sliding block 62.

[0118] At least part of the first rotating portion 6121 is rotatably sleeved on the outer wall of the connecting portion 611, and the observer can directly operate the first rotating portion 6121 to drive the movement of the entire rotating portion 612. The first rotating portion 6121 and the connecting portion 611 are clearance-matched, and this design allows the first rotating portion 6121 to freely rotate and axially move on the connecting portion 611 without excessive friction or resistance.

[0119] The first rotating portion 6121 is sleeved on the outer wall of the connecting portion 611 , which can reduce the entry of foreign matter into the cavity and play a certain protective role on the mechanical components in the cavity.

[0120] The second rotating part 6122 is connected to the first rotating part 6121, and the rotational motion of the first rotating part 6121 can be transmitted to the second rotating part 6122. The first rotating part 6121 can be fixedly connected to the second rotating part 6122 by threaded connection, clamping or welding. The second rotating part 6122 is located inside the cavity and is threadedly connected to the inner wall of the cavity to convert the rotational motion of the second rotating part 6122 into linear motion, so that the second rotating part 6122 can perform linear motion along the inner wall of the cavity when rotating.

[0121] The outer end of the third rotating portion 6123 along the second direction is connected to the second rotating portion 6122, and the linear motion of the second rotating portion 6122 is transmitted to the third rotating portion 6123. The inner end of the third rotating portion 6123 abuts against the first slider 62, and the linear motion of the third rotating portion 6123 can directly push the first slider 62 to slide along the second direction.

[0122] In actual use, the observer drives the rotational motion of the entire rotating part 612 by operating the first rotating part 6121. Due to the threaded connection between the second rotating part 6122 and the inner wall of the cavity, the rotational motion will be converted into linear motion along the second direction. The linear motion is transmitted to the third rotating part 6123 through the connection between the second rotating part 6122 and the third rotating part 6123, and finally pushes the first slider 62 to slide through the inner end of the third rotating part 6123.

[0123] In this embodiment, by providing the first rotating portion 6121, the second rotating portion 6122 and the third rotating portion 6123, the operating accuracy and stability of the first knob 61 are improved, so that the observer can more accurately control the sliding distance and speed of the first slider 62. The multiple rotating portions 612 of this subdivided design not only improve the performance and reliability of the first knob 61, but also provide a more convenient and precise operating experience.

[0124] In some embodiments, Figure 7 As shown, the cavity includes a first cavity portion 6111 and a second cavity portion 6112 arranged along the second direction, and the inner wall of the first cavity portion 6111 is provided with a plurality of grooves 6113, and the plurality of grooves 6113 are arranged circumferentially around the first cavity portion 6111; the second spiral portion 6122 is provided with a protrusion 61221, and the protrusion 61221 is installed on the second spiral portion 6122 along the radial sliding of the second spiral portion 6122, and the end of the protrusion 61221 protrudes from the outer peripheral wall of the second spiral portion 6122 and stops at the groove 6113; the second spiral portion 6122 is threadedly connected to the second cavity portion 6112.

[0125] In this embodiment, the end of the protruding member 61221 protrudes from the outer peripheral wall of the second rotating portion 6122 and stops at the groove body 6113. When the second rotating portion 6122 rotates relative to the first cavity portion 6111, the protruding member 61221 rotates with the second rotating portion 6122 and the outer end of the protruding member 61221 slides along the plurality of groove bodies 6113. Since the protruding member 61221 is installed on the second rotating portion 6122 along the radial direction of the second rotating portion 6122, the protruding member 61221 is aligned with the groove body 6113. In this case, the protrusion 61221 will be bounced into the groove body 6113, and the end of the protrusion 61221 will collide with the bottom of the groove to make a "click" sound, thereby improving the observer's control over the rotation angle and the rotation experience. At the same time, when the rotation of the first knob 61 stops, the end of the protrusion 61221 can be located in the groove body 6113, and the groove body 6113 locks or positions the protrusion 61221, reducing the retreat of the first knob 61 and improving the adjustment accuracy and stability of the laser 3.

[0126] The protrusion 61221 is elastically connected to the second rotating portion 6122 so that the protrusion 61221 retreats when it slides over the top of the groove and pops out when it slides into the groove, thereby reducing the wear of the protrusion 61221 and the groove body 6113 and playing a protective role.

[0127] In some embodiments, Figure 7 As shown, multiple grooves 6113 extend axially along the first cavity portion 6111, so that when the rotating portion 612 rotates forward along the connecting portion 611, the grooves 6113 can play a locking or positioning role, reducing the retreat of the first knob 61 and improving the adjustment accuracy and stability of the laser 3.

[0128] In some embodiments, Figure 6 As shown, the first adjusting member 6 further includes: a first restoring member 64, and two ends of the first restoring member 64 are respectively connected to the laser 3 and the housing 1.

[0129] Exemplarily, the first reset member 64 may be a spring or a spring. When the observer stops rotating the first knob 61 or rotates the first knob 61 in the opposite direction, the first reset member 64 pushes the laser 3 back to the initial position.

[0130] When the laser 3 is in the initial position, the emission direction of the laser 3 is parallel to the direction of the light path.

[0131] In some embodiments, Figure 6 As shown, the first restoring member 64 includes a first connecting piece 641, a second connecting piece 642 and an elastic member 643 connecting the first connecting piece 641 and the second connecting piece 642. The first connecting piece 641 and the second connecting piece 642 are arranged opposite to each other. The first connecting piece 641 is connected to the laser 3, and the second connecting piece 642 is connected to the housing 1.

[0132] The first connecting piece 641 , the second connecting piece 642 and the elastic member 643 may be integrally formed and connected or welded.

[0133] The first connecting piece 641 and the second connecting piece 642 are arranged opposite to each other. The first connecting piece 641 is connected to the laser 3. When the position of the laser 3 changes, the first connecting piece 641 will also move accordingly. The second connecting piece 642 is connected to the housing 1 to improve the overall stability of the first reset member 64.

[0134] The elastic member 643 may be a spring or a spring sheet structure, and the elastic member 643 plays a role of resetting and buffering. When the laser 3 is lifted to a new position by the second slider 63, the elastic member 643 will be stretched to store a certain potential energy. When the observer stops rotating the first knob 61 or rotates the first knob 61 in the opposite direction, the elastic member 643 will release the stored potential energy and push the laser 3 back to the initial position.

[0135] In this embodiment, by providing the first reset member 64, the observer can adjust the position of the laser 3 as needed without worrying about over-adjustment or failure to return to the original position after adjustment. At the same time, the buffering effect of the elastic member 643 can also reduce the impact and vibration that may be generated during the adjustment process, protect the laser 3 and the housing 1, and improve the accuracy of the through-window observation and aiming device.

[0136] In some embodiments, Figure 8As shown, the second adjusting member 7 includes: a second knob 71 and a third slider 72; the slider of the second adjusting member 7 is the third slider 72, and the second knob 71 is rotatably mounted on the housing 1; the third slider 72 is rotatably mounted on the avoidance groove 18 of the housing 1 around the axis of the second rotating shaft 52, the third slider 72 is connected to the laser 3, and the connection position is spaced apart from the second rotating shaft 52, and the second knob 71 is suitable for abutting against the third slider 72.

[0137] The third slider 72 and the laser 3 can be fixedly connected by threaded connection, welding or snap connection.

[0138] The structure of the second knob 71 can be the same as that of the first knob 61. The second knob 71 converts rotational motion into linear motion during rotation. When the second knob 71 abuts against the third slider 72, the second knob 71 pushes the third slider 72 to rotate around the second rotation axis 52. Since the third slider 72 is connected to the laser 3, the movement of the third slider 72 can drive the laser 3 to rotate around the second rotation axis 52, thereby realizing the angle adjustment of the laser 3 swinging left and right in the plane.

[0139] In this embodiment, the observer can rotate the second knob 71 to drive the third slider 72 to rotate around the second rotation axis 52, thereby driving the laser 3 to rotate around the second rotation axis 52 to achieve left and right swing adjustment of the laser 3 in the plane.

[0140] The avoidance groove 18 of the housing 1 is provided with an arc surface to avoid the rotational movement of the third sliding block 72 .

[0141] In some embodiments, Figure 8 As shown, the second adjusting member 7 further includes: a second restoring member 73 , a movable end of the second restoring member 73 along the second direction abuts against the third sliding block 72 , and the other end of the second restoring member 73 is connected to the housing 1 .

[0142] The second reset member 73 resets and stabilizes the third slide, and two ends of the second reset member 73 are respectively connected to the third slide block 72 and the housing 1. Exemplarily, the second reset member 73 can be a spring pin or an elastic sheet structure.

[0143] The movable end of the second reset member 73 abuts against the third slider 72. When the position of the third slider 72 changes, the movable end of the second reset member 73 also moves accordingly, thereby storing a certain amount of potential energy. When the observer stops rotating the second knob 71 or rotates the second knob 71 in the opposite direction, the second reset member 73 releases the stored potential energy, pushing the third slider 72 back to the initial position, and the third slider 72 drives the laser 3 back to the initial position.

[0144] In some embodiments, Figure 4 , Figure 5 and Figure 7 As shown, the through-window viewing device also includes: a quick-release structure 8, which includes: a guide rail 81, a connecting seat 82 and a locking block 83; the bottom wall of the guide rail 81 is connected to the top wall of the housing 1; the connecting seat 82 is connected to the bottom end of the laser 3, the first rotating shaft 51, the second rotating shaft 52, the first adjusting member 6 and the second adjusting member 7 are arranged on the connecting seat 82, and the bottom end of the connecting seat 82 is provided with a card slot 821 adapted to the guide rail 81; the locking block 83 passes through the connecting seat 82 and abuts against the guide rail 81.

[0145] The laser 3 is connected to the housing 1 via a quick-release structure 8 , so as to facilitate quick installation and removal of the laser 3 relative to the housing 1 .

[0146] The shape and size of the guide rail 81 are adapted to the slot 821 of the connecting seat 82, so that the connecting seat 82 can be accurately inserted into the guide rail 81 to achieve quick release of the laser 3. The bottom end of the connecting seat 82 is provided with a slot 821 adapted to the guide rail 81. When the connecting seat 82 can be placed on the guide rail 81 along the extension direction of the guide rail 81, the slot 821 will slide along the guide rail 81 until it is fully inserted and fixed on the guide rail 81.

[0147] The locking block 83 plays the role of locking and fixing the connecting seat 82. When the connecting seat 82 is correctly installed on the guide rail 81, the locking block 83 will be pushed or screwed into the appropriate position to form a close abutment relationship with the guide rail 81 to prevent the connecting seat 82 from loosening or shifting during operation.

[0148] In actual use, align the slot 821 at the bottom of the connecting seat 82 with the guide rail 81 and slide until it is fully inserted. Then, the connecting seat 82 is locked on the guide rail 81 by the locking block 83. The entire installation process does not require the use of complex tools or cumbersome operations, achieving fast and convenient installation. This design not only improves the efficiency of installation and disassembly, but also reduces the difficulty of operation, allowing the observer to complete the installation and disassembly of the laser 3 more easily. At the same time, the clamping and locking structure between the connecting seat 82 and the guide rail 81 improves the stability and reliability of the laser 3 during operation.

[0149] In some embodiments, Figure 7 As shown, the side wall of the guide rail 81 includes a first surface and a second surface that are connected, the first surface and the second surface form an angle, and the connecting end of the first surface and the second surface protrudes from the side wall of the guide rail 81; the first side wall of the slot 821 includes a third surface and a fourth surface, the third surface is arranged opposite to the first surface of one side of the guide rail 81, and the fourth surface is arranged opposite to the second surface of the side; the second side wall of the slot 821 includes a fifth surface, the fifth surface is parallel to the fourth surface, and a portion of the fifth surface is arranged opposite to the first surface of the other side of the guide rail 81.

[0150] The connecting ends of the first surface and the second surface protrude from the side wall of the guide rail 81 to form a protruding structure, which can fit tightly with the card slot 821 of the connecting seat 82 to achieve a more stable card connection effect and provide precise guidance and positioning.

[0151] The first side wall of the slot 821 includes a third surface and a fourth surface. This corresponding design enables the connecting seat 82 to slide smoothly and accurately when inserted into the guide rail 81, while improving the stability of the card connection; the second side wall of the slot 821 includes a fifth surface, and the fifth surface is parallel to the fourth surface. During installation, the fifth surface and the fourth surface can be aligned with the guide rail 81 and pushed into the guide rail 81 in an inclined direction, thereby eliminating the need to sleeve the slot 821 on the guide rail 81 from the end of the guide rail 81, thereby improving the convenience of operation and further achieving quick and secure installation.

[0152] In this embodiment, since the contact area between the card slot 821 and the guide rail 81 is large and multiple surfaces are designed to cooperate with each other, this structure also has good impact and vibration resistance and can maintain stable performance in a complex working environment.

[0153] In some embodiments, Figure 1 , Figure 2 and Fig. 9 As shown, the through-window viewing and aiming device provided by the present application includes: a housing 1 and a lens group 2; the end of the housing 1 is open; the lens group 2 includes an objective lens assembly 21 and an eyepiece lens assembly 22, the objective lens assembly 21 and the eyepiece lens assembly 22 are arranged in sequence in the housing 1 along the optical path, the objective lens assembly 21 includes an objective lens barrel 211 and a mounting bracket 212, a portion of the mounting bracket 212 is located in the housing 1 and connected to the housing 1, the mounting bracket 212 is provided with a mounting groove 2121, and at least a portion of the objective lens barrel 211 is arranged in the mounting groove 2121; wherein, the objective lens barrel 211 and the mounting bracket 212 are connected by at least two sections of threads arranged at intervals, and the objective lens barrel 211 and the mounting bracket 212 are matched by a support surface 214 between the at least two sections of threads.

[0154] Part of the mounting frame 212 is located inside the housing 1 and connected to the housing 1, so that the objective lens assembly 21 can be stably mounted on the housing 1, thereby improving the accuracy of the objective lens assembly 21. The mounting frame 212 is provided with a mounting groove 2121, and at least part of the objective lens barrel 211 is mounted in the mounting groove 2121.

[0155] The connection mode between the objective lens barrel 211 and the mounting rack 212 adopts at least two sections of thread connection, and the two sections of thread are spaced apart. This design not only enhances the stability and reliability of the connection between the objective lens barrel 211 and the mounting rack 212, but also makes it more convenient to adjust or replace the objective lens barrel 211. In addition, the objective lens barrel 211 and the mounting rack 212 are also matched by the support surface 214 between at least two sections of thread, and the support surface 214 can play a guiding and supporting role, which can improve the stability and precision of the connection between the objective lens barrel 211 and the mounting rack 212, and reduce the displacement or deviation caused by vibration or external force.

[0156] In the related art, the objective lens barrel and the mounting frame are usually connected by a thread. In order to improve the reliability and stability of the connection between the objective lens barrel and the mounting frame, the axial length of the threaded connection is usually lengthened. However, the above structure, due to the long thread length, prolongs the assembly time between the objective lens and the mounting frame, and increases the difficulty of assembly.

[0157] According to the through-window aiming device provided in the embodiment of the present application, the objective lens barrel 211 and the mounting bracket 212 are connected by at least two sections of threads that are spaced apart, and a smooth supporting surface 214 is provided between the at least two sections of threads, and the two sections of threads are matched with each other through the supporting surface 214. In this assembly structure, the threaded connection requires the objective lens barrel 211 to be rotated and inserted into the mounting bracket 212, which can improve the connection stability between the objective lens barrel 211 and the mounting bracket 212, reduce the displacement or deviation caused by vibration or external force, and improve the imaging effect of the objective lens assembly 21, and the surface-to-surface matching can directly insert the objective lens barrel 211 into the mounting bracket 212 without the need for rotating and tightening operations, which can shorten the installation time and reduce the difficulty of assembly. At the same time, the surface-to-surface matching can play a guiding and supporting role and improve the assembly accuracy; at the same time, the threaded connection between the objective lens barrel 211 and the mounting bracket 212 can realize the forward and backward movement of the objective lens barrel 211 relative to the mounting bracket 212, thereby ensuring imaging at different depths of field.

[0158] In some embodiments, Fig. 9As shown, the objective lens barrel 211 includes a first barrel portion 2111 and a second barrel portion 2112, the first barrel portion 2111 and the second barrel portion 2112 are arranged in sequence along the optical path, and the outer diameter of the first barrel portion 2111 is greater than the outer diameter of the second barrel portion 2112; the mounting groove 2121 includes a first groove portion 21211 and a second groove portion 21212, the outer diameter of the first groove portion 21211 is greater than the outer diameter of the second groove portion 21212, and at least a portion of the first barrel portion 2111 is located in the first groove portion 21211 The second barrel portion 2112 is located in the second groove portion 21212; the at least two sections of threads include a first thread 2131 and a second thread 2132, the first barrel portion 2111 and the first groove portion 21211 are connected by the first thread 2131 and the support surface 214, and the support surface 214 is arranged at one end of the first barrel portion 2111 and the first groove portion 21211 close to the second barrel portion 2112; the second barrel portion 2112 and the second groove portion 21212 are connected by the second thread 2132.

[0159] Among them, the first barrel portion 2111 and the second barrel portion 2112 are arranged in a step shape, the first groove portion 21211 and the second groove portion 21212 are arranged in a step shape, and the second groove portion 21212 limits the first barrel portion 2111 to avoid the objective lens barrel 211 from transitionally moving along the axial direction, thereby improving the assembly accuracy of the objective lens barrel 211 and the mounting groove 2121.

[0160] Among them, the first thread 2131 is arranged between the first barrel 2111 and the first groove 21211, and the second thread 2132 is arranged between the second barrel 2112 and the second groove 21212. The objective lens barrel 211 and the mounting frame 212 are connected at two positions at the same time to achieve multi-point connection and improve the stability of the connection.

[0161] The support surface 214 is disposed at one end of the first barrel portion 2111 and the first groove portion 21211 close to the second barrel portion 2112 , and the support surface 214 plays a guiding role so that the first barrel portion 2111 can be smoothly matched and connected with the first groove portion 21211 .

[0162] In some embodiments, Fig. 9 As shown, the end of the first barrel portion 2111 along the extension direction of the optical path forms a chamfer with the side wall of the first barrel portion 2111, which reduces the stress concentration on the outer edge of the first barrel portion 2111, protects the first barrel portion 2111 and the first groove portion 21211, and reduces the difficulty of removing the first barrel portion 2111 from the first groove portion 21211.

[0163] In some embodiments, Fig. 9 and Fig.10 As shown, the mounting frame 212 is provided with a through hole 21213 ; the objective lens assembly 21 further includes an anti-dropout pin 215 , one end of which passes through the through hole 21213 and stops at the objective lens barrel 211 .

[0164] The anti-dropout nail 215 can be a bolt or a screw. The through hole 21213 is threadedly connected with the stud of the anti-dropout nail 215.

[0165] In this embodiment, the stud portion of the anti-slip pin 215 is inserted into the through hole 21213 of the mounting frame 212, and the top end of the anti-slip pin 215 is pressed against or fixed on the objective lens barrel 211, which can improve the connection stability between the objective lens barrel 211 and the mounting frame 212, while reducing the risk of the objective lens barrel 211 falling off or shifting, thereby improving the imaging reliability of the lens group 2.

[0166] In some embodiments, Fig. 9 As shown, the objective lens assembly 21 further includes a sealing member 216 , which is sandwiched between the objective lens barrel 211 and the mounting bracket 212 .

[0167] The sealing member 216 may be a sealing ring, such as a rubber ring, a silicone ring or a plastic ring, etc. The sealing member 216 may be fixed between the objective lens barrel 211 and the mounting frame 212 by compression, bonding or other means, thereby improving the stability of the connection between the objective lens barrel 211 and the mounting frame 212 and having certain anti-leakage and anti-dust functions; at the same time, by providing the sealing member 216, the elasticity of the sealing member 216 itself may be utilized to reduce the gap between the objective lens barrel 211 and the mounting frame 212, thereby reducing the offset of the central axis of the optical lens and improving the aiming accuracy.

[0168] In this embodiment, by providing a seal 216 between the objective lens barrel 211 and the mounting bracket 212, the stability of the connection between the objective lens barrel 211 and the mounting bracket 212 is improved, and the leakage and dustproof effects of the equipment are improved, so that the through-window aiming device can be applied to humid or dusty environments, thereby increasing the diversity of usage scenarios; at the same time, the dust, dirt or water vapor entering between the objective lens barrel 211 and the mounting bracket 212 can be reduced, which is beneficial to maintaining a good fit between the objective lens barrel 211 and the mounting bracket 212 and increasing the service life of both.

[0169] In some embodiments, at least one of the outer wall of the objective lens barrel 211 and the inner wall of the mounting bracket 212 is provided with an annular groove, and at least a portion of the sealing member 216 is disposed in the annular groove.

[0170] The size and sealing performance of the annular groove are adapted so that the sealing member 216 can be completely or fully embedded in the annular groove.

[0171] In this embodiment, the annular groove is used to position and fix the seal 216 to reduce the movement, misalignment or twisting deformation of the seal 216, and the seal 216 and the annular groove can cooperate to form a combination of multiple sealing methods such as labyrinth seals and packing seals to improve the sealing effect.

[0172] In some embodiments, Fig.10 As shown, the sealing member 216 includes a plurality of sealing members 216 , and the plurality of sealing members 216 are spaced apart and distributed along the axial direction of the objective lens barrel 211 .

[0173] The sealing members 216 may include two, three or more sealing members 216, and the sealing effect may be further enhanced by the plurality of sealing members 216. The number of the annular grooves may also include multiple, and the multiple annular grooves may be matched and assembled with the multiple sealing members 216 in a one-to-one correspondence.

[0174] In some embodiments, Fig.10 As shown, a protrusion 217 is disposed on the outer wall of the objective lens barrel 211 , and the outer diameter of the protrusion 217 is larger than the inner diameter of the mounting groove 2121 .

[0175] Among them, because the outer diameter of the protrusion 217 is greater than the inner diameter of the mounting groove 2121, the protrusion 217 can be used as a positioning point for the objective lens barrel 211 to cooperate with the mounting frame 212. When the objective lens barrel 211 is inserted into the mounting frame 212, the protrusion 217 interacts with the edge of the mounting groove 2121, so that the objective lens barrel 211 is correctly aligned and fixed.

[0176] In some embodiments, the protrusion block 217 includes a plurality of protrusion blocks 217 , and the plurality of protrusion blocks 217 are spaced apart and distributed along the circumference of the objective lens barrel 211 .

[0177] In this embodiment, the protrusions 217 can also increase the structural strength of the objective lens barrel 211, making it more able to withstand external pressure and vibration. At the same time, the observer can rotate the objective lens barrel 211 by twisting the protrusions 217 distributed at circumferential intervals, which is more convenient and labor-saving.

[0178] In some embodiments, Figure 1 and Figure 2 As shown, the through-window aiming device further includes: a laser 3, which is movably mounted outside the housing 1 and is spaced apart from the objective lens assembly 21 and the eyepiece assembly 22.

[0179] In this embodiment, the laser 3 can be used for fill light, and the lens group 2 cooperates with the laser 3 to realize the day and night observation function of the through-window observation device.

[0180] The laser 3 is movably installed outside the casing 1. The position of the laser 3 can be fine-tuned relative to the casing 1. The observer can fine-tune the position and emission direction of the laser 3 to adjust the incident angle of the laser beam and focus and position the laser beam, thereby meeting the fill light requirements of the target at different positions and improving the aiming accuracy of the through-window aiming device.

[0181] Among them, the lens group 2 and the laser 3 are both installed in the housing 1, the lens group 2 can be completely located in the housing 1, or partially located in the housing 1, and the laser 3 is installed outside the housing 1, that is, the laser 3 and the lens group 2 are located in different working environments, and the laser 3 is separated from the lens group 2. Therefore, the laser 3 and the lens group 2 are located in different working environments, and the heat generated during the operation of the laser 3 will directly enter the external environment through the heat dissipation holes 311, which can improve the heat dissipation effect of the laser 3, so that the laser 3 can maintain a proper temperature when working for a long time, improve the working stability of the emitting device 32, and prevent overheating from affecting the performance of the emitting device 32, and at the same time reduce the influence of the heat of the laser 3 on the lens group 2, improve the working stability of the lens group 2, and prevent overheating from affecting the performance of the lens group 2; on the other hand, the laser 3 is separated from the lens group 2, and there is a certain distance between the laser beam and the optical path, which can reduce the interference of the scattered light generated by the laser beam on the imaging of the lens group 2, and improve the imaging effect.

[0182] In some embodiments, Figure 3 As shown, the through-window viewing and aiming device also includes a base 9, which is arranged at the bottom of the housing 1, and is used for detachably connecting with the launching device 32.

[0183] The launching device 32 may be a device that requires day and night sighting functions.

[0184] The seat body 9 can be detachably connected to the launching device 32 by means of a snap connection, a plug-in connection or a threaded connection.

[0185] In some embodiments, Figure 3 As shown, a snap-in groove 91 adapted to the connecting rail at the top of the launching device 32 is provided at the bottom of the seat body 9 , and the seat body 9 is snap-connected with the launching device 32 .
