DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The core of the present invention is to provide an eyepiece structure, which can meet the needs of human eyes to observe and take pictures to form images by setting a camera module connected to one side of the eyepiece tube, and can meet the use requirements of the eyepiece structure to take pictures and record. Another core of the present invention is to provide an eyepiece system and a night vision device including the above eyepiece structure.

[0052] The eyepiece structure provided by the present invention includes an eyepiece module and a camera module 4, please refer to Figure 1 , Figure 2 .

[0053] The eyepiece module includes an eyepiece tube 6 arranged along the first optical axis and a spectroscopic device arranged in the eyepiece tube 6. The spectroscopic device can at least split the incident light into a transmission part to continue to be transmitted along the first optical axis for human eye observation; it can also split the incident light into an output part, and the light of the output part is transmitted along the second optical axis direction for shooting. Figure 3 , the first optical axis is Figure 3 The X direction is shown in the figure, and the second optical axis is Figure 3 The Y direction is indicated in the figure.

[0054] In this embodiment, the spectrometer can also divide the incident light into a reflection part, a refraction part, etc., and can be flexibly designed according to the actual use requirements of the eyepiece structure without limiting the function of the spectrometer.

[0055] Further, the camera module 4 connected to one side of the eyepiece tube 6 is used for shooting, specifically, the camera 2-8 arranged along the second optical axis receives the output part to form an image, thereby meeting the functional requirements of the eyepiece structure for recording. The image here is in the form of a photo or a video, without limitation.

[0056] In one usage scenario, such as during the day when there is sufficient light, the incident light can be directly divided into an outgoing part and a transmitted part by a spectroscopic device, and the image captured by the camera 2-8 can be clearly seen.

[0057] In another usage scenario, such as in the evening or at night, before the spectroscopic device operates, it is necessary to first convert the low-illuminance incident light into visible light through a processing element, and then the processed incident light is divided into a transmission part and an output part through the spectroscopic device. After that, the image captured by the camera 2-8 after receiving the output part is a clear and visible image, and the projected part that can be observed by the human eye is also clearly visible. The operating principle and specific structure of the conversion element here are not repeated here, and the conventional components that can meet the light conversion requirements can be used as a reference.

[0058] In this embodiment, the first optical axis and the second optical axis can be set vertically or at a certain angle. Specifically, they are set based on the optical path of the output part separated by the splitter, so that the camera 2-8 set along the second optical axis can receive the output part, and the camera 2-8 does not affect the optical path transmission of the transmitted part.

[0059] In this embodiment, the camera module 4 may have its own storage element, which can store the captured images so that the observer can retrieve and use them later according to needs.

[0060] The eyepiece structure provided by the present invention can be for right eye or left eye, and there is no limitation on this point. However, it should be noted that the position of the camera module 4 is different in the eyepiece structure under the right eye and left eye conditions, such as Fig.10 The right eye is shown. If it is changed to the left eye, the camera module 4 needs to be rotated 180 degrees around the axis of the first optical axis to facilitate observation and ensure that the camera module 4 can shoot at a straight-on angle to ensure that shooting and human eye observation do not interfere with each other.

[0061] On the basis of the above embodiment, the outer periphery of the eyepiece tube 6 is provided with an escape opening 6-1, please refer to Figure 8 .

[0062] An avoidance opening 6-1 is provided on the outer periphery of the eyepiece barrel 6, and the camera 2-8 passes through the avoidance opening 6-1 and is arranged toward the first optical axis so that the camera 2-8 is located on the optical path of the rotating part, achieving the effect of being able to form an image by shooting.

[0063] There is no limitation on the size and shape of the avoidance opening 6 - 1 , as long as it can allow the camera 2 - 8 to pass through and receive the light corresponding to the rotated-out part.

[0064] Based on any of the above embodiments, please refer to Figure 1 , Figure 3 , Figure 6 The eyepiece module includes a lens body 2-7 arranged in the eyepiece barrel 6, and a connecting portion 2-7-1 is protruded from the outer periphery of the lens body 2-7. The connecting portion 2-7-1 is arranged in the avoidance opening 6-1 and connected to the inner cavity of the lens body 2-7. The camera 2-8 is fixed to the connecting portion 2-7-1 and the lens of the camera 2-8 is arranged toward the inner cavity of the lens body 2-7.

[0065] The connecting portion 2-7-1 is specifically a component protruding from the side wall of the lens body 2-7, and can fix the camera 2-8 by opening a mounting groove 2-7-2, thereby avoiding directly opening a groove on the lens body 2-7 to affect the structural strength.

[0066] The connecting portion 2-7-1 can fix the camera 2-8 on the lens body 2-7. Specifically, the connecting portion 2-7-1 is arranged in the avoidance opening 6-1 to realize the positioning of the lens body 2-7 relative to the eyepiece barrel 6. For example, the connecting portion 2-7-1 can be attached to the inner wall of the avoidance opening 6-1 for positioning, or the connecting portion 2-7-1 and the inner wall of the avoidance opening 6-1 have a certain adjustable installation gap.

[0067] After the camera 2-8 is fixed by the connecting part 2-7-1, the lens of the camera 2-8 can be set toward the inner cavity of the lens body 2-7, and the light from the rotated part can pass through the inner cavity to reach the lens position of the camera 2-8, so that the camera 2-8 can take a clear image, thereby realizing the recording function of the eyepiece structure.

[0068] Based on any of the above embodiments, please refer to Figure 6 The connecting part 2-7-1 is provided with a mounting groove 2-7-2, and the mounting groove 2-7-2 is connected to the inner cavity of the lens body 2-7. The mounting groove 2-7-2 and / or the connecting part 2-7-1 are provided with a plurality of positioning parts, and the positioning parts are used to fix the camera 2-8 to the connecting part 2-7-1.

[0069] Please refer to Figure 3The mounting groove 2-7-2 is a through hole opened on the connecting part 2-7-1. The through hole can be in the form of a stepped hole or a single through hole, which can be connected to the inner cavity of the lens body 2-7, so that part of the outgoing light can pass through the inner cavity through the mounting groove 2-7-2 to reach the lens position of the camera 2-8, so as to facilitate shooting.

[0070] In a specific embodiment, a plurality of positioning parts can be provided on the mounting groove 2-7-2. When the lens part of the camera 2-8 is installed in the mounting groove 2-7-2, the positioning part can provide an installation reference, and then the camera 2-8 is fixed on the connecting part 2-7-1. By setting the positioning part, the camera 2-8 can be accurately and reliably fixed on the connecting part 2-7-1, thereby ensuring the accuracy of the installation of the camera 2-8 and ensuring a reliable shooting effect.

[0071] In another specific embodiment, a plurality of positioning parts are provided on the connecting part 2-7-1. When the camera 2-8 is fixed on the connecting part 2-7-1, it can be positioned first so that the lens part of the camera 2-8 has a reference benchmark when it extends into the installation groove 2-7-2, thereby ensuring the accuracy of the installation of the camera 2-8 and ensuring the reliable shooting effect of the camera 2-8.

[0072] Based on any of the above embodiments, please refer to Figure 6 The mounting groove 2-7-2 includes a first positioning groove 2-7-2-1 and a second positioning groove 2-7-2-2 which are sequentially arranged along the second optical axis direction. The second positioning groove 2-7-2-2 communicates with the first positioning groove 2-7-2-1 and the inner cavity of the lens body 2-7. The positioning portion is arranged on the groove wall of the first positioning groove 2-7-2-1 and the second positioning groove 2-7-2-2. The first positioning groove 2-7-2-1 and the second positioning groove 2-7-2-2 form a stepped mounting groove, and the stepped groove provides a positioning and mounting effect for the camera 2-8.

[0073] Please refer to Figure 2 When the camera 2-8 is installed, the outer periphery of the lens part of the camera 2-8 and the groove walls of the first positioning groove 2-7-2-1 and the second positioning groove 2-7-2-2 are fitted to form a positioning effect, and then the main part of the camera 2-8 and the connecting part 2-7-1 are connected through the holes and fasteners.

[0074] The second positioning groove 2-7-2-2 is connected to the inner cavity of the lens body 2-7, and the lens part of the camera 2-8 is wrapped around the outer periphery of the second positioning groove 2-7-2-2. The lens is specifically arranged toward the inner cavity of the lens body 2-7 to receive the light corresponding to the output part separated by the spectroscopic device, and shoot to form an image, so that the human eye can observe and record the observed image at the same time.

[0075] Based on any of the above embodiments, please refer to Figure 1 , Figure 2 , Figure 3 , further comprising a lens body 2-7 and a body shell 2-10, wherein the lens body 2-7, the body shell 2-10, and the eyepiece barrel 6 are sequentially arranged from the inside to the outside. The eyepiece barrel 6 is fixedly connected to the body shell 2-10, and the fixed connection here can be specifically made with the aid of a fastener 7, please refer to Figure 8 , Figure 7 Specifically, a first connecting hole 6-2 is provided on the eyepiece barrel 6, a third connecting hole 2-10-3 is provided on the main body shell 2-10, and the fastener 7 passes through the first connecting hole 6-2 and the third connecting hole 2-10-3 to form a fixation, so that the fastener 7 and the main body shell 2-10 form a relatively fixed relationship.

[0076] In this embodiment, the connection between the lens body 2-7 and the camera module 4 is a detachable connection, such as through a pin 5. Specifically, when connecting, the pin 5 can be fixed to the lens body 2-7 or the camera module 4 in advance, and when connecting, it is only necessary to pass through one of them to tighten, thereby improving the efficiency of assembly and disassembly.

[0077] Please refer to Figure 2 , Figure 3 The eyepiece barrel 6 is fixedly connected to the main body shell 2-10, and the lens body 2-7 is connected to a moving component, which can push the lens body 2-7 to move along the first optical axis direction to perform diopter adjustment operations.

[0078] The moving assembly can push the lens body 2-7 to move along the first optical axis, so that the camera 2-8 connected to the lens body 2-7 can move synchronously to adjust the vision. The camera 2-8 is a voice coil motor camera, which can automatically focus. When the camera 2-8 moves, the voice coil motor of the camera 2-8 works, thereby achieving the focusing effect, so as to capture a clear image.

[0079] In this embodiment, the movement of the lens body 2-7 is bidirectional, and the specific movement is determined in combination with the image being photographed until a clear image is captured.

[0080] In this embodiment, the moving component can be specifically a sliding block that penetrates the main body shell 2-10 and the eyepiece barrel 6, the sliding block is connected to the lens body 2-7, and the sliding block can be manually pushed or pulled to slide along the slide grooves on the main body shell 2-10 and the eyepiece barrel 6 to achieve the movement of the lens body 2-7, the movement of the camera 2-8, and the effect of focusing. Here, the direction of the slide groove is parallel to the first optical axis direction.

[0081] In this embodiment, the moving component can also be a common rotating wheel and a power conversion element. The rotating wheel can rotate relative to the axis of the main body shell 2-10 and the eyepiece barrel 6, and the power conversion element can convert the rotation into movement. The lens body 2-7 is connected through the power conversion element, and the movement of the lens body 2-7 can also be achieved, and then the focusing effect can be achieved through the movement of the camera 2-8. The moving component in this embodiment is such as a gear rack structure.

[0082] Based on any of the above embodiments, the focusing hand wheel 2-5 has a first connecting ring 2-5-1 and a second connecting ring 2-5-2, the first connecting ring 2-5-1 is threadedly connected to the end of the lens body 2-7, and the second connecting ring 2-5-2 is rotatably mounted on the main body shell 2-10 or the eyepiece barrel 6; wherein the first connecting ring 2-5-1 and the second connecting ring 2-5-2 are coaxially arranged.

[0083] Please refer to the figure, the main body shell 2-10 and the eyepiece barrel 6 are fixedly connected, so the second connecting ring 2-5-2 can be sleeved on either one. When the first connecting ring 2-5-1 rotates, due to the limitation of the second connecting ring 2-5-2 by the main body shell 2-10 or the eyepiece barrel 6, the focusing hand wheel 2-5 rotates in place, and after the force of the threaded connection is transmitted to the lens body 2-7, the lens body 2-7 can be pushed to move along the first optical axis relative to the main body shell 2-10 and the eyepiece barrel 6 to perform the diopter adjustment operation. Specifically, a limiting groove / block can be set through the lens body 2-7, and a limiting block / groove can be set corresponding to the main body shell 2-10. The groove direction of the limiting groove is set along the first optical axis. Under the cooperation of the limiting groove and the limiting block, even if the first connecting ring 2-5-1 is threadedly connected to the end of the lens body 2-7, when the focusing hand wheel 2-5 rotates, due to the cooperation of the limiting groove and the limiting block, the movement of the lens body 2-7 can only be a translation along the first optical axis.

[0084] Taking a specific implementation as an example, the first connecting ring 2-5-1 and the second connecting ring 2-5-2 correspond to the inner ring and outer ring of the focus hand wheel 2-5, respectively. In this way, the second connecting ring 2-5-2 is the outer ring part, which is sleeved on the inner ring of the main body shell 2-10, and the first connecting ring 2-5-1 is the internal thread part, which can be threadedly connected with the end of the lens body 2-7.

[0085] Taking another specific implementation as an example, the first connecting ring 2-5-1 and the second connecting ring 2-5-2 are arranged in sequence along the first optical axis direction. In this way, the focusing hand wheel 2-5 is a hollow structure and has a step on the outer periphery. This arrangement is convenient for satisfying the situation where there is a distance between the end of the main body shell 2-10 and the end of the lens body 2-7, so that the first connecting ring 2-5-1 can be threadedly connected to the end of the lens body 2-7, and the second connecting ring 2-5-2 can be rotatably mounted on the main body shell 2-10.

[0086] Taking another specific implementation as an example, the first connecting ring 2-5-1 and the second connecting ring 2-5-2 are connected by a connecting wall 2-5-4. Figure 5 As shown, the connecting wall 2-5-4, the inner ring of the second connecting ring 2-5-2, and the outer ring of the first connecting ring 2-5-1 jointly form a limiting area, and the end of the main body shell 2-10 is located in the limiting area. By setting the limiting area, the main body shell 2-10 can be limited, ensuring the reliable stability when the focusing hand wheel 2-5 rotates, and ensuring reliable focusing operation.

[0087] Based on any of the above embodiments, please refer to Figure 3 , Figure 5 The moving assembly includes a focusing hand wheel 2-5, and the focusing hand wheel 2-5 has a first connecting ring 2-5-1 and a second connecting ring 2-5-2 coaxially arranged therewith, and the first connecting ring 2-5-1 is connected to the second connecting ring 2-5-2 through a connecting wall 2-5-4.

[0088] The first connecting ring 2-5-1 is threadedly connected to the end of the lens body 2-7, which is the end close to the eyeball when in use. The second connecting ring 2-5-2 is rotatably mounted in the arc groove 2-10-1 at the end of the main shell 2-10, which is the end close to the eyeball when in use. The arc groove 2-10-1 is coaxial with the main shell 2-10 and both ends of the arc groove 2-10-1 extend to the avoidance opening 6-1. When the second connecting ring 2-5-2 rotates, it actually rotates counterclockwise or clockwise around the axis of the main shell 2-10, which can also be said to be a rotation around the axis direction of the first optical axis.

[0089] The second connecting ring 2-5-2 is connected to a rotating member located in the arc groove 2-10-1, and the rotating member can rotate around the arc groove 2-10-1 to realize the rotation of the focus hand wheel 2-5 around the first optical axis. By setting the rotating member to be located in the arc groove 2-10-1, when the focus hand wheel 2-5 rotates, it can reliably realize the rotation around the first optical axis, avoid the deviation of the focus hand wheel 2-5, ensure that the lens body 2-7 can reliably move along the first optical axis, and ensure the focusing effect.

[0090] In this embodiment, the rotating member can be a raised arc-shaped structure on the focus hand wheel 2-5, or a arc-shaped structure that can be detachably connected to the focus hand wheel 2-5. The specific curvature of the arc-shaped structure here is not limited and can be flexibly set according to actual conditions.

[0091] Based on any of the above embodiments, please refer to Figure 2The rotating part includes at least two arc pressure rings 2-6 arranged in the arc groove 2-10-1, and at least two arc pressure rings 2-6 are arranged around the axial direction of the arc groove 2-10-1. When the focusing hand wheel 2-5 rotates, at least two arc pressure rings 2-6 rotate around the arc groove 2-10-1 to make the focusing hand wheel 2-5 rotate in situ, and further based on the threaded connection between the focusing hand wheel 2-5 and the lens body 2-7, the cooperation of the limit groove and the limit block, the rotation force is converted into a force for the lens body 2-7 to move along the first optical axis, thereby realizing the movement of the camera 2-8.

[0092] Taking a specific implementation as an example, the second connecting ring 2-5-2 of the focusing hand wheel 2-5 is connected to the arc pressure ring 2-6 through the connecting member 8. Specifically, the connecting member 8 passes through the second connecting hole 2-5-3 on the second connecting ring 2-5-2 to achieve a fixed connection between the arc pressure ring 2-6 and the second connecting ring 2-5-2.

[0093] When the focusing hand wheel 2-5 rotates, at least two arc pressure rings 2-6 rotate around the arc groove 2-10-1, wherein the arc pressure ring 2-6 is limited by the limit of the arc groove 2-10-1 and can only rotate within the arc groove 2-10-1, ensuring that when the focusing hand wheel 2-5 rotates, it rotates precisely around the axis of the first optical axis, ensuring the accuracy of controlling the movement of the camera 2-8 along the axis of the main shell 2-10, and ensuring reliable focusing.

[0094] In this embodiment, at least two arc-shaped pressing rings 2-6 may not be in contact with each other, so that when the focusing hand wheel 2-5 rotates, each arc-shaped pressing ring 2-6 can rotate reliably.

[0095] Specifically, during focusing operation, the eyepiece barrel 6, the main body shell 2-10, and the fastener 7 serve as the fixed component A, the focusing hand wheel 2-5, the connecting piece 8, and the arc pressure ring 2-6 serve as the rotating component B, and the lens body 2-7, the moving block 2-11, and the camera module 4 serve as the moving component C.
