Technical Field

[0001] This application relates to the technical field of digital microscopes, and more particularly to a digital module and a digital microscope. Background Technology

[0002] Digital microscopes are products that combine traditional microscope optics with modern digital technology. They can convert the optical images observed by traditional optical microscopes into digital signals and display them on a monitor, allowing users to observe samples in a comfortable and efficient manner.

[0003] The structure of a digital microscope mainly includes a traditional optical observation module and an added digital module. The function of the digital module is to receive the optical images observed by the optical observation module and convert them into digital signals, and finally display the sample images on the display terminal connected to the digital module.

[0004] A utility model patent with authorization announcement number CN209471297U discloses a "microscope screen reference base assembly with image optical path tube position adjustment function," which includes a photoelectric conversion module (i.e., a digital module). The photoelectric conversion module includes a housing and a CCD / CMOS circuit board and an optical path tube assembly installed in the housing. The housing is connected to a base or microscope support and is generally a one-piece injection molded mounting slot with an opening on one side. Components such as the CCD / CMOS circuit board are located in the mounting slot. Because electronic components can be damaged after prolonged use, the above-mentioned digital microscope structure requires complete disassembly and repair of the digital module, which is inconvenient for maintenance. Utility Model Content

[0005] To facilitate the repair of digital modules, the primary objective of this application is to provide a digital module.

[0053] The present application will be further described in detail below with reference to the accompanying drawings.

[0054] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] Figure 1 and Figure 2 The diagram illustrates the structure of a digital microscope, including a microscope support 10 and a digital module 20 mounted on the support 10. The digital module 20 converts optical signals into digital signals and can be connected to an external device terminal to output or display image information. Specifically, the support 10 includes a frame base 11, within which a miniature mirror 30 is disposed. The digital module 20 is detachably connected to the frame base 11, and the miniature mirror 30 is positioned below the digital module 20.

[0057] Combination Figures 3 to 5The digital module 20 includes a split first housing 21 and a second housing 22. The first housing 21 and the second housing 22 are connected and together form an installation cavity 227 with an opening on one side. The installation cavity 227 contains a motherboard 23 and a CMOS component connected to the motherboard 23.

[0058] The first housing 21 includes a base plate 211 and limiting plates 212 extending outward from both sides of the base plate 211. A gap exists between the two limiting plates 212 to form a latch 213. The motherboard 23 is engaged within the latch 213 in either its width or length direction, achieving initial positioning between the motherboard 23 and the first housing 21. A slot 214 is also formed on the side of the limiting plate 212 facing the latch 213. Both sides of the motherboard 23 extend into the slot 214, and the slot 214 has a certain length allowing the motherboard 23 to slide along the opening direction of the slot 214.

[0059] The second housing 22 includes an integral cover 221. The cover 221 has a connected mounting port 224 and a clearance port 225. When the first housing 21 is connected to the second housing, the two limiting parts of the first housing 21 can be partially inserted into the mounting port 224 to achieve the initial positioning of the two. At the same time, after the two are combined, the aforementioned mounting cavity 227 is formed inside. The clearance port 225 is connected to the mounting cavity 227 and is opened facing the side of the frame base 11. The condenser mirror 30 extends into the mounting cavity 227.

[0060] The housing 221 also has a protrusion 226 on its inner wall. The protrusion 226 protrudes towards the mounting port 224. The main board 23 has a limiting notch 231 on the side near the second housing 22. When the main board 23 is connected to the second housing 22, the limiting notch 231 and the protrusion 226 engage with each other to limit the movement of the main board 23 in one direction.

[0061] The second housing 22 also includes a first extension plate 222 and a second extension plate 223 connected to the housing 221. The first extension plate 222 extends upward from the mounting opening 224, and the second extension plate 223 is located on one side of the clearance opening 225. The first extension plate 222 abuts against the upper end face of the first housing, and the two are connected by fasteners to realize the connection between the first housing 21 and the second housing 22. The second extension plate 223 abuts against the upper end face of the frame base 11, while the lower end face of the first housing 21 also abuts against the upper end face of the frame base 11. The first housing 21 and the frame base 11, as well as the second extension plate 223 and the frame base 11, are connected by fasteners to realize the connection between the first housing 21, the second housing 22, and the frame base 11.

[0062] Combination Figure 6The second housing 22 is provided with a positioning block 228 on the lower end surface of the housing 221, and a positioning groove 12 is provided on the frame base 11. The positioning block 228 can be locked in the positioning groove 12 to realize the installation positioning between the second housing 22 and the frame base 11.

[0063] Combination Figure 7 During the observation of sample 40, the optical path 50 passes sequentially through the beam splitter prism 60, the first reflector 70, and the second reflector 80 before being projected onto the image reduction mirror 30. After passing through the image reduction mirror 30, the optical path 50 strikes the CMOS component. The CMOS component includes a CMOS circuit board 24 and a mounting base 25 connected to the CMOS circuit board 24 via fasteners. The mounting base 25 is connected to the image reduction mirror 30. The CMOS circuit board 24 is connected to the motherboard 23 via a flexible flat cable. After striking the CMOS circuit board 24, the optical path 50 converts the optical signal into a digital signal, which is then processed by the motherboard 23. To output the required signal, the motherboard 23 includes at least one I / O interface, which can be any one or a combination of USB interface 233, DP interface, HDMI interface, VGA interface, and Ethernet interface 232. In this embodiment, the I / O interface is provided with a USB interface 233 and a network cable interface 232. The USB interface 233 can be used to connect to a device terminal, such as a monitor, to display images. Correspondingly, a connection port 215 for the corresponding I / O interface is provided on the first housing 21 to facilitate wiring.

[0064] Meanwhile, in this embodiment, a WiFi antenna 26i is also installed on one side of the second housing 22. The WiFi antenna 26i is electrically connected to the motherboard 23, and wireless transmission can be achieved through the WiFi antenna 26i. Of course, the WiFi antenna 26i can also be installed on the first housing 21.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
