[0110] In this embodiment, the focusing handwheel 13 is connected to the lens assembly 22 via a transmission mechanism 40 including a linkage. By rotating the focusing handwheel 13, the transmission mechanism 40 can be driven to adjust the distance between the lens assembly 22 and the camera core 21, thereby achieving focusing. Compared to the objective lens end 20, the eyepiece end 10 is closer to the human eye. By placing the focusing handwheel 13 at the eyepiece end 10 of the viewing device, the operator does not need to extend their hand a considerable distance when focusing, making the focusing process more effortless and more comfortable.

[0111] Specifically, as shown in Figure 2, the eyepiece assembly includes an eyepiece knob 111, an eyepiece lens 112, and an eyepiece display screen 113. By rotating the eyepiece knob 111, the distance between the eyepiece lens 112 and the eyepiece display screen 113 can be adjusted. The eyepiece display screen 113 is used to display the control interface.

[0112] As shown in Figures 1 and 2, the observation and aiming device also has a second control module 33, which is located on the connecting housing 30. The second control module 33 includes a second control button knob 331, which is an encoder knob used for menu selection and confirmation.

[0114] In this embodiment, the connecting housing is used to house the main connecting rod 41, and the lens housing 23 is used to house the first auxiliary connecting rod. The connecting housing and the lens housing 23 can protect and prevent dust from the internal transmission mechanism 40, lens assembly 22, focusing handwheel 13, etc. The operating housing 121, the connecting housing 30, and the lens housing 23 are connected in sequence, so that the main connecting rod 41 and the first auxiliary connecting rod 42 can be smoothly transmitted. With the above configuration, the operator rotates the focusing handwheel 13, which drives the lens assembly 22 to slide relative to the housing through the transmission connection between the main connecting rod 41 and the first auxiliary connecting rod 42, thereby achieving focusing.

[0115] In some embodiments of this application, the diameter of the connecting housing 30 is smaller than the diameter of the lens housing 23; the main connecting rod 41 and the first auxiliary connecting rod 42 are misaligned, that is, the radial distance between the main connecting rod 41 and the front and rear central axis of the viewing device is different from the radial distance between the first auxiliary connecting rod 42 and the front and rear central axis of the viewing device.

[0116] In this embodiment, since the diameter of the connecting housing 30 is small, the operator can hold the connecting housing 30 more securely and comfortably. According to the internal structure of the connecting housing 30 and the lens housing 23, the main connecting rod 41 and the first auxiliary connecting rod 42 are staggered to minimize the impact of the transmission mechanism on the large diameter of the lens housing and the small diameter of the connecting housing.

[0117] In some embodiments of this application, the main connecting rod 41 is disposed near the edge of the connecting housing 30, and the first auxiliary connecting rod 42 is disposed near the lens housing 23 and spaced apart from the camera core 21.

The transmission mechanism 40 further includes: a first sub-transmission mechanism 43. The first sub-transmission mechanism 43 is respectively connected to the second end of the first auxiliary connecting rod 42 and the connecting part 2212 of the focusing lens barrel 221 to convert the rotational force of the first auxiliary connecting rod 42 into a horizontal pulling force, thereby driving the focusing lens barrel 221 to slide in the horizontal direction within the lens housing 23.

[0120] In this embodiment, the lens mounting portion 2211 of the focusing lens barrel 221 can accommodate a lens. By adjusting the horizontal movement of the focusing lens barrel 221, that is, adjusting the movement of the lens located within the focusing lens barrel 221, focusing is achieved. The first limiting portion 241 of the limiting member 24 can limit the sliding direction of the focusing lens barrel 221, improving the accuracy and stability of the sliding of the focusing lens barrel 221, thereby improving the accuracy of focusing. The first sub-transmission mechanism 43 can convert the rotational force of the first auxiliary connecting rod 42 into a horizontal pulling force, driving the focusing lens barrel 221 to slide horizontally, thereby adjusting the distance between the optical lens and the camera core 21 in the focusing lens barrel 221. Since the first sub-transmission mechanism 43 can convert the rotational force of the first auxiliary connecting rod 42 into a horizontal pulling force, the first auxiliary connecting rod 42 does not move, thus reducing interference with other components and improving the stability of the transmission.

[0121] Specifically, as shown in Figures 3 and 4, the connecting portion 2212 is provided with a first sealing groove 22123a, and the viewing device also includes a first sealing element (not shown), which is disposed within the first sealing groove 22123a. The first sealing element is located between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, providing a sliding seal between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, preventing dust from entering the camera core 21 from between the lens housing 23 and the focusing lens barrel.

[0122] As shown in Figures 3 and 4, the lens mounting portion 2211 is provided with a second sealing groove 22123b, and the viewing device also includes a second sealing element (not shown), which is disposed within the second sealing groove 22123b. The second sealing element is located between the lens mounting portion 2211 and the lens housing 23 of the focusing lens barrel 221, providing a sliding seal between the connecting portion 2212 of the focusing lens barrel 221 and the lens housing 23, preventing dust from entering the camera core 21 from between the lens housing 23 and the focusing lens barrel.

[0123] In some embodiments of this application, as shown in Figures 1, 2, 3, and 4, the first sub-transmission mechanism 43 includes: a first drive gear 431 and a first driven wheel 432; the first end of the first drive gear 431 is fixedly connected to the second end of the first auxiliary connecting rod 42, and the second end of the first drive gear 431 has a first external tooth; the first driven wheel 432 is located inside the lens housing 23 and is partially sleeved outside the connecting portion 2212 of the focusing lens barrel 221, and its inner wall periphery is sequentially provided with a first internal tooth 4321 and a first internal thread (not shown) in a direction away from the connecting housing 30; the first external tooth of the first drive gear 431 meshes with the first internal tooth 4321 to drive the first driven wheel 432 to rotate; the outer wall of the connecting portion 2212 of the focusing lens barrel 221 is provided with a first external thread 2213 that cooperates with the first internal thread of the first driven wheel 432 to drive the focusing lens barrel 221 to slide horizontally inside the lens housing 23.

[0124] In this embodiment, since the first drive gear 431 is fixedly connected to the second end of the first auxiliary connecting rod 42, and the first auxiliary connecting rod 42 is connected to the main connecting rod 41, when the focusing handwheel 13 is rotated, the main connecting rod 41 drives the first auxiliary connecting rod 42 to rotate, which in turn drives the first drive gear 431 to rotate. Since the first drive gear 431 meshes with the first internal tooth 4321 of the first driven wheel 432, the first driven wheel 432 rotates. Since the first internal thread of the first driven wheel 432 is also connected to the first external thread 2213 of the focusing lens barrel 221, and the first limiting part of the limiting member 24 limits the movement direction of the focusing lens barrel 221, the rotation of the first driven wheel 432 can drive the focusing lens barrel 221 to slide in the horizontal direction, thereby adjusting the distance between the optical lens inside the focusing lens barrel 221 and the camera core 21, thus achieving focusing.

[0125] In some embodiments of this application, as shown in Figures 1, 2, 3, and 4, the connecting portion 2212 of the focusing lens barrel 221 includes: a threaded portion 22121 and a second limiting portion 22122; a first external thread 2213 is disposed on the outer periphery of the threaded portion 22121 and engages with the first internal thread of the first driven wheel 432; the second limiting portion 22122 engages with the first limiting portion 241; and a first elastic member 25 is disposed between the second limiting portion 22122 and the limiting member 24.

[0126] In this embodiment, the first elastic member 25 is disposed between the limiting member 24 and the focusing lens barrel 221. After the limiting member 24 and the focusing lens barrel 221 are assembled, the first elastic member 25 is in a compressed state. Under the elastic force of the first elastic member 25, the axial gap of the thread between the focusing lens barrel 221 and the first driven wheel 432 can be eliminated.

[0127] Specifically, the threaded portion 22121 is an arc-shaped threaded portion 22121, which facilitates engagement with the first internal thread of the first driven wheel 432; the second limiting portion 22122 is a planar limiting portion, and the limiting member 24 has a limiting plate. The outer surface of the limiting plate is arc-shaped, which matches the shape of the inner wall of the lens housing 23, and the inner side of the limiting plate is planar, fitting against the second limiting portion 22122. More specifically, the number of first limiting portions 241 can be the same as the number of second limiting portions 22122, or the number of first limiting portions 241 can be different from the number of second limiting portions 22122. As shown in Figure 3, there can be two first limiting portions 241, and correspondingly, two second limiting portions 22122.

[0128] Specifically, the first limiting part 241 may also be a limiting groove provided on the connecting part 2212, the groove extending in a horizontal direction, and the second limiting part 22122 may be a limiting rod that cooperates with the limiting groove. This application does not limit the shape of the first limiting part 241 and the second limiting part 22122.

[0129] Specifically, as shown in Figure 4, the first driven wheel 432 is provided with a first limiting step 4322, and the side of the first limiting step 4322 abuts against the limiting member 24.

[0130] In some embodiments of this application, as shown in FIG3, the limiting member 24 has an annular groove 242 formed on the side away from the focusing lens barrel 221; the outer ring wall of the annular groove 242 has a notch 2421; the first driving gear 431 passes through the bottom wall of the annular groove 242, and the first external tooth portion of the first driving gear 431 is located in the notch 2421; a gear pressure plate 26 is provided on the end face of the second end of the first driving gear 431, the gear pressure plate 26 is fixedly connected to the outer side wall of the annular groove 242, and the first auxiliary connecting rod 42 passes through the gear pressure plate 26 and is fixedly connected to the first driving gear 431.

[0131] In this embodiment, the annular groove 242 provides space for the first drive gear 431 and the gear plate 26, resulting in a more compact structure and space saving. The first external tooth portion of the first drive gear 431 is located within the notch 2421. The notch 2421 prevents interference between the first drive gear 431 and the annular groove 242 after rotation, improving reliability during transmission. The first auxiliary connecting rod 42 passes through the gear plate 26 and is fixedly connected to the first drive gear 431. The gear plate 26 provides support for the first auxiliary connecting rod 42, reducing the probability of breakage of the first auxiliary connecting rod 42 near the first drive gear 431.

[0133] In this embodiment of the application, as shown in Figures 1, 5 and 6, the first auxiliary connecting rod 42 is connected to the main connecting rod 41 in a transmission manner, and the second end of the first auxiliary connecting rod 42 is inserted into the threaded hole of the bushing 434. When the focusing handwheel 13 is rotated, the main connecting rod 41 drives the first auxiliary connecting rod 42 to rotate. Since the bushing 434 is fixedly connected to the focusing lens barrel 221 by threads, and the first limiting part of the limiting member plays a limiting role in the movement direction of the focusing lens barrel 221, the focusing lens barrel 221 can slide in the horizontal direction, thereby adjusting the distance between the optical lens inside the focusing lens barrel 221 and the camera core 21, thereby achieving focusing.

[0135] In this embodiment, the connecting rod clearance groove 211 can prevent the first auxiliary connecting rod 42 from interfering with the camera core 21 during rotation, thereby improving the stability and reliability of the first auxiliary connecting rod 42 during transmission.

[0137] In this embodiment, the first gearbox 441 houses the first main connecting rod transmission gear 442, the intermediate transmission gear 443, and the first auxiliary connecting rod transmission gear 444.

The first main connecting rod transmission gear 442 is fixedly connected to the main connecting rod 41, and the first auxiliary connecting rod transmission gear 444 is fixedly connected to the first auxiliary connecting rod 42. This achieves a staggered arrangement of the main connecting rod 41 and the first auxiliary connecting rod 42 in a direction perpendicular to the main connecting rod 41, preventing interference between them during transmission and resulting in a more rational internal structural layout of the observation and aiming equipment.

[0138] Specifically, the first gearbox 441 includes a first gearbox cover 4411 and a second gearbox cover 4412. The first gearbox cover 4411 and the second gearbox cover 4412 can be fixedly connected by snap-fit ​​or threaded connection. The first main connecting rod drive gear 442, the intermediate drive gear 443 and the first auxiliary connecting rod drive gear 444 are located in the receiving space formed by the first gearbox cover 4411 and the second gearbox cover 4412.

[0139] More specifically, the first main connecting rod transmission gear 442, the intermediate transmission gear 443, and the first auxiliary connecting rod transmission gear 444 each have a first main connecting rod transmission gear shaft 4421, an intermediate transmission gear shaft 4431, and a first auxiliary connecting rod transmission gear shaft 4441, respectively. The main connecting rod is fixedly connected to the first main connecting rod transmission gear shaft 4421 by screws, and the first auxiliary connecting rod is fixedly connected to the first auxiliary connecting rod transmission gear shaft 4441 by screws. The first gearbox cover 4411 has three first mounting shaft holes 44110, which are respectively positioned opposite to the positions of the first main connecting rod transmission gear shaft 4421, the intermediate transmission gear shaft 4431, and the first auxiliary connecting rod transmission gear shaft 4441. The first main connecting rod transmission gear shaft 4421, the intermediate transmission gear shaft 4431, and the first auxiliary connecting rod transmission gear shaft 4441 are rotatably connected to the three first mounting shaft holes 44110. Similarly, the second gearbox cover 4412 is provided with a second mounting shaft hole 44120 corresponding to the first mounting shaft hole 44110.

[0140] It should be noted that the transmission ratios of the first main connecting rod transmission gear 442, the intermediate transmission gear 443, and the first auxiliary connecting rod transmission gear 444 can be set according to actual needs, and this application does not limit the transmission ratios.

[0141] In some embodiments of this application, as shown in Figures 1, 10, 11, 12, 13, and 14, Figure 10 is a schematic diagram of the cooperation between the first type of focusing handwheel, the first control module, the handwheel pressure frame, and part of the transmission mechanism in an embodiment of this application; Figure 11 is an exploded view of the first type of focusing handwheel, the first control module, the handwheel pressure frame, and part of the transmission mechanism shown in Figure 10; Figure 12 is a schematic diagram of the connection between the transmission mechanism, the focusing handwheel, and the focusing lens barrel in the observation and aiming device of the first embodiment shown in Figure 10; Figure 13 is a schematic diagram of the connection between the first type of focusing handwheel and the third sub-transmission mechanism shown in Figure 12; Figure 14 is a schematic diagram of the connection between the first auxiliary connecting rod shown in Figure 12 and the focusing lens barrel; the focusing handwheel 13 of the eyepiece end 10 is disposed between the control housing 121 and the eyepiece assembly 11; the focusing handwheel 13 is provided with a first focusing internal tooth 131 near the inner wall periphery of the first control module 12. The transmission mechanism 40 further includes: a second drive gear 45, a second auxiliary connecting rod 46, and a third sub-transmission mechanism 47; the second drive gear 45 is fixedly connected to the first end of the second auxiliary connecting rod 46 and is provided with a first focusing external tooth 451; the first focusing external tooth 451 of the second drive gear 45 cooperates with the first focusing internal tooth 131 of the focusing handwheel 13 to drive the second auxiliary connecting rod 46 to rotate under the drive of the focusing handwheel 13; the second end of the second auxiliary connecting rod 46 passes through the control housing 121 of the first control module 12 and is connected to the third sub-transmission mechanism 47; the third sub-transmission mechanism 47 is located at the position where the connecting housing 30 is connected to the control housing 121, and is connected between the second auxiliary connecting rod 46 and the main connecting rod 41 to realize the transmission connection between the second auxiliary connecting rod 46 and the main connecting rod 41.

[0142] In this embodiment, the focusing handwheel 13 of the eyepiece end 10 is located between the control housing 121 and the eyepiece assembly 11, closer to the eyepiece assembly 11 on the control housing 121. This eliminates the need for the user to extend their hand far when turning the focusing handwheel 13, improving the comfort of manual focusing. The focusing handwheel 13 has a first focusing internal tooth 131. Turning the focusing handwheel 13 rotates the first focusing internal tooth 131. Since the first focusing internal tooth 131 meshes with the second drive gear 45, and the second drive gear 45 is fixedly connected to the second auxiliary connecting rod 46, the second drive gear 45 can drive the second auxiliary connecting rod 46 to rotate. The second auxiliary connecting rod 46 is connected to the first auxiliary connecting rod 42 via the main connecting rod 41. The second auxiliary connecting rod 46 rotates through the third sub-transmission mechanism 47, driving the main connecting rod 41 to rotate.

It protects the second auxiliary connecting rod transmission gear 472 and the second main connecting rod transmission gear 473 from dust, preventing dust from falling onto the gears and causing gear transmission jamming, thus making the gear transmission process smoother. The second auxiliary connecting rod transmission gear 472 and the second main connecting rod transmission gear 473 are arranged sequentially along a direction perpendicular to the main connecting rod 41. The second main connecting rod transmission gear 473 is fixedly connected to the main connecting rod 41, and the second auxiliary connecting rod transmission gear 472 is fixedly connected to the second auxiliary connecting rod 46. This achieves a staggered arrangement of the main connecting rod 41 and the second auxiliary connecting rod 46 in a direction perpendicular to the main connecting rod 41, preventing interference between the main connecting rod 41 and the second auxiliary connecting rod 46 during transmission, and making the internal structural layout of the observation and aiming equipment more reasonable.

[0146] Specifically, as shown in Figure 11, the second gearbox 471 includes a third gearbox cover 4711 and a fourth gearbox cover 4712, which are fixedly connected. The second auxiliary connecting rod transmission gear 472 and the second main connecting rod transmission gear 473 are located in the accommodating space formed between the third gearbox cover 4711 and the fourth gearbox cover 4712.

[0148] In some embodiments of this application, as shown in Figures 15, 16, 17, 18, and 19, Figure 15 is a partial cross-sectional view of the observation and aiming device of the second embodiment provided in this application; Figure 16 is an exploded view of the focusing handwheel, the first control module, part of the transmission mechanism, and the connecting housing in the observation and aiming device of the second embodiment shown in Figure 15; Figure 17 is an internal structural diagram of the focusing handwheel, the first control module, part of the transmission mechanism, and the connecting housing shown in Figure 16; Figure 18 is a schematic diagram of the connection between the transmission mechanism, the focusing handwheel, and the focusing lens barrel in the observation and aiming device of the second embodiment shown in Figure 15; Figure 19 is a schematic diagram of the connection between the focusing handwheel and the main connecting rod shown in Figure 18; the focusing handwheel 13 of the eyepiece end 10 is disposed between the control housing and the connecting housing 3.

[0149] Specifically, the rotating operating part 132 may be provided with embossing. The embossing can increase the friction between the hand and the rotating operating part, making the operation of the rotating focusing handwheel easier.

[0150] In this embodiment, the focusing handwheel 13 of the eyepiece end 10 is disposed between the control housing and the connecting housing 30. The second focusing internal tooth 134 of the focusing handwheel 13 engages with the second focusing external tooth of the third drive gear 48. The third drive gear 48 is fixedly connected to the main connecting rod 41. When the focusing handwheel 13 is rotated, the second focusing internal tooth 134 rotates, driving the second focusing external tooth to rotate, thereby driving the main connecting rod 41 to rotate. Since the main connecting rod 41 is connected to the first auxiliary connecting rod 42, the main connecting rod 41 drives the first auxiliary connecting rod 42 to rotate, thereby adjusting the horizontal displacement of the focusing lens barrel 221, and thus achieving focusing.

[0151] In some embodiments of this application, as shown in Figures 16 and 19, the focusing handwheel 13 includes: a rotating wheel body 135 and an operating handle 136 disposed outside the rotating wheel body 135; the second focusing inner tooth 134 is located on the inner circumferential side of the rotating wheel body 135.

[0152] In this embodiment, the operating handle 136 is located on the outside of the rotating wheel 135. A person can directly rotate the operating handle 136 to drive the rotating wheel 135 to rotate. Since the operating handle 136 protrudes from the rotating wheel 135, when the human eye observes the eyepiece end 10, it is easier to reach out and identify and touch the protruding operating handle 136, making the focusing process faster.
