Description

Technical Field

[0001] This solution relates to the field of head-mounted low-light night vision devices, specifically a night vision device with a detachable recording module structure. Background Technology

[0002] Existing head-mounted low-light night vision goggles are often just ordinary goggles with lenses, allowing observation through the human eye without video recording capabilities. Alternatively, the entire system's functions are concentrated around the goggles, and the miniature camera module is not detachable, resulting in an overall large module size.

[0003] In modern society, in order to expand people's range of perception, head-mounted devices are not simply night vision devices. They usually integrate helmets, voice communication systems, and so on. If the modules are too large, it will lead to installation difficulties or interference with other devices during installation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable video recording module structure for a head-mounted night vision device.

[0005] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A night vision device with a detachable video recording module structure, the night vision device includes an eyepiece tube, the eyepiece tube includes an inner tube, a middle tube, an outer shell and a focusing ring, the outer shell is detachably connected to the night vision device by threads, the middle tube is fixedly connected to the outer shell by screws, the middle tube is provided with an oblong hole, the inner tube is slidably disposed in the middle tube, the inner tube is provided with a pin at a position adapted to the oblong hole, the pin is disposed in the oblong hole, the inner tube is provided with an annular limiting groove at the end near the observed object, the limiting groove is provided with a slip ring, and the focusing ring is fixed on the slip ring by screws;

[0007] The inner cylinder is fixedly provided with a lens assembly. The inner cylinder is threadedly connected to the focusing ring. The focusing ring is used to drive the inner cylinder to move axially by rotating.

[0008] The inner cylinder is also provided with a video recording module interface, which is used to airtightly receive the miniature camera module, and the lens group is used to transmit part of the collected light to the miniature camera module.

[0009] This invention offers the following advantages over existing technologies:

[0010] With its compact structure and rational design, the miniature camera module achieves an airtight connection with the night vision device through the recording module interface. This not only ensures stable operation of the miniature camera module in harsh environments but also allows users to quickly replace or upgrade the miniature camera module according to actual needs, avoiding interference with other components and improving the applicability and flexibility of the night vision device. Meanwhile, the focus ring design allows users to adjust the focus with a simple rotation, making operation convenient and quick, enhancing the user experience. Furthermore, the robust connections of all components in this structure ensure the overall stability and durability of the night vision device.

[0011] Furthermore, a sealing protrusion is provided at the interface connecting the miniature camera module and the eyepiece tube, and a sealing groove is provided at the corresponding interface of the miniature camera module, with a flexible sealing ring provided in the sealing groove.

[0012] The fitting design of the sealing ring and sealing groove ensures the airtightness of the connection between the miniature camera module and the eyepiece tube, effectively preventing external moisture, dust, and other impurities from entering the night vision device, further guaranteeing the stable operation of the miniature camera module and the internal components of the night vision device. The use of a flexible sealing ring not only enhances the sealing effect but also, due to its good elasticity and wear resistance, can adapt to changes in environmental conditions such as temperature and humidity, extending the service life of the sealing structure. This design detail once again demonstrates the high importance this invention places on product durability and applicability, providing users with a more reliable and efficient night vision observation experience.

[0013] Furthermore, the miniature camera module has a positioning pin at its bottom and a corresponding positioning hole on the eyepiece tube.

[0014] The design of the positioning pins and holes ensures quick and accurate positioning of the miniature camera module during installation, preventing misalignment or loosening caused by improper installation. This design not only improves installation efficiency but also ensures a stable connection between the miniature camera module and the night vision device, further guaranteeing recording quality and the overall performance of the night vision device. Simultaneously, the positioning pins and holes facilitate quick positioning when disassembling the recording module, simplifying the operation process and enhancing the user experience.

[0015] Furthermore, the miniature camera module is fixed to the inner cylinder of the eyepiece tube by a beveled screw.

[0016] Furthermore, the inclined screws are in two sets, which are respectively inclined from both sides towards the middle to fix the miniature camera module.

[0017] The angled screw design generates forces in both the vertical and horizontal directions during locking, creating a three-dimensional compression effect on the sealing ring between the miniature camera module and the inner cylinder. This further enhances the sealing performance, strengthening the connection between the miniature camera module and the inner cylinder and effectively preventing loosening issues caused by uneven force distribution, which can occur with traditional straight screws. Furthermore, the angled screw's tilt from both sides towards the center allows for more even force distribution during installation, improving stability and reliability.

[0018] This design consists of two parts: an eyepiece and a miniature camera module. The eyepiece and the miniature camera module are detachable for easy assembly, which makes the eyepiece + miniature camera module assembly more competitive in the market. Attached Figure Description
