[0035] The purpose of this invention is to provide a TF card interface sealing structure that does not occupy space and has good sealing and waterproof performance.

[0036] To achieve the above objectives, the present invention provides the following technical solution:

[0037] Please see Figures 1 to 5 This embodiment provides a sealing structure for a TF card, used to seal the TF card slot 01 of an infrared low-light night vision device, including: a housing 100 and a waterproof cover 200; the outer wall of the housing 100 has a through-type insertion port 110 corresponding to the position of the TF card slot 01, and the outer periphery of the insertion port 110 is provided with a recessed mounting groove 120; the waterproof cover 200 is movably connected to the housing 100, and the waterproof cover 200 can be engaged in the mounting groove 120 to seal the insertion port 110.

[0038] Specifically, the housing 100 is the outer shell of the infrared low-light night vision device, and other components of the infrared low-light night vision device are installed inside it. The TF card slot 01, which corresponds to the insertion of the TF card 02, is located close to the inner side of one side wall of the housing 100. Therefore, in order to facilitate the insertion of the TF card 02 by the user, a strip-shaped through-hole 110 is provided at the position of the TF card slot 01 in the housing 100, so that the TF card 02 can be inserted into the TF card slot 01 inside the housing 100. In other words, sealing the through-hole 110 on the housing 100 is to seal and protect the TF card slot 01.

[0039] Furthermore, in order to seal and protect the socket 110, a movable waterproof cover 200 is attached to the housing 100 near the socket 110. In addition, a recessed mounting groove 120 is provided on the outer side wall of the housing 100. The size of the mounting groove 120 matches the waterproof cover 200, so that the waterproof cover 200 can be installed into the mounting groove 120, thereby sealing and protecting the socket 110 and achieving a sealing and waterproof effect.

[0040] It should be noted that, in order to maximize the sealing effect, the waterproof cover 200 is made of a flexible material, and its overall size is slightly larger than that of the mounting groove 120. That is, the two are interference fit after assembly. This setting allows the waterproof cover 200 to completely fill the mounting groove 120, preventing water from entering the socket 110 through the gaps and then entering the TF card slot 01.

[0041] In one possible embodiment, the waterproof cover 200 includes: a cover body 210 and a connecting post 220; the cover body 210 has the same shape as the mounting groove 120 so that the cover body 210 is fitted into the mounting groove 120; the connecting post 220 is vertically connected to the cover body 210, and the connecting post 220 passes through the side wall of the housing 100 and is located in the mounting groove 120 to prevent the cover body 210 from separating from the housing 100.

[0042] Specifically, such as Figures 2 to 3 As shown, in this embodiment, the waterproof cover 200 includes two parts: a cover body 210 for filling the mounting groove 120 and sealing the socket 110, and a connecting post 220 for connecting the waterproof cover 200 to the housing 100. Preferably, the mounting groove 120 in this embodiment is square. Correspondingly, the cover body 210 of the waterproof cover 200 is also square to match the mounting groove 120, and the size of the cover body 210 is slightly larger than the size of the mounting groove 120, so that the cover body 210 is in an interference fit when assembled into the mounting groove 120. Of course, the shapes of the mounting groove 120 and the cover body 210 can be adjusted appropriately according to actual conditions, as long as the sealing socket 110 is satisfied. It should be noted that in this embodiment, the socket 110 is located in the middle of the mounting groove 120 to maximize the sealing effect.

[0043] To prevent the infrared low-light night vision device from detaching from the mounting slot 120 after the waterproof cover 200 is assembled, a connecting post 220 is also provided on the waterproof cover 200. The connecting post 220 is embedded in the inner wall of the housing 100. With this configuration, the waterproof cover 200 is simply opened to expose the slot 110 each time the TF card 02 is inserted or removed. In other states, the waterproof cover 200 is always connected to the mounting slot 120, which can improve the protection effect of the TF card slot 01.

[0044] In one possible embodiment, the bottom of the mounting groove 120 is provided with a through-hole 130 for the connecting post 220 to pass through. The end of the connecting post 220 facing away from the cover 210 is provided with a stop protrusion 230 for preventing the connecting post 220 from detaching from the connecting hole 130.

[0045] Specifically, such as Figures 3 to 5As shown, in this embodiment, a through-hole 130 is provided at the bottom of the mounting groove 120, and a stop protrusion 230 is provided at the end of the connecting post 220 to prevent the waterproof cover 200 from detaching from the housing 100. The connecting hole 130 is located at the bottom left of the mounting groove 120, avoiding the position of the insertion port 110 as much as possible. The end of the connecting post 220 after passing through the connecting hole 130 is provided with a stop protrusion 230 with a size larger than that of the connecting hole 130. The stop protrusion 230 can prevent the connecting post 220 from detaching from the connecting hole 130. Furthermore, glue is applied at the connection between the connecting hole 130 and the stop protrusion 230 to reinforce both, which is also to seal the connecting hole 130 and prevent water from entering the housing 100 from the connecting hole 130.

[0046] In one possible embodiment, the connecting post 220 has a waist-shaped cross-section, and the connecting hole 130 and the connecting post 220 are interference fit.

[0047] Specifically, in this embodiment, both the connecting post 220 and the connecting hole 130 have an oblong cross-section. This design increases the strength of the connecting post 220 and prevents it from breaking. The connecting hole 130 is designed to fit the shape of the connecting post 220, thereby reducing the gap between them and increasing the sealing effect.

[0048] In one possible embodiment, a plurality of fixing posts 240 are vertically arranged on the inner side of the cover 210, and a plurality of fixing holes 140 that cooperate with the fixing posts 240 are provided at the bottom of the mounting groove 120, so as to fix and install the waterproof cover 200.

[0049] Understandably, in order to prevent the cover 210 from not engaging securely with the mounting groove 120, thus preventing gaps between them, this embodiment also provides several vertical fixing posts 240 on the inner side of the cover 210, and several fixing holes 140 are provided at corresponding positions at the bottom of the mounting groove 120, as detailed below. Figures 3 to 5 As shown, with this configuration, when the cover 210 mates with the mounting groove 120, the fixing post 240 will be inserted into the fixing hole 140. This makes the connection between the cover 210 and the mounting groove 120 more stable and less prone to gaps, thus making it less likely for the cover 210 to detach from the mounting groove 120. It should be noted that the fixing post 240 and the fixing hole 140 are also fitted with an interference fit.

[0050] In one possible embodiment, three fixing posts 240 are provided, two of which are located at one end of the cover 210 away from the connecting post 220, and one fixing post 240 is located at the other end of the cover 210.

[0051] Furthermore, in this embodiment, three fixing posts 240 are provided on the back of the cover 210, two of which are arranged side by side at one end of the cover 210 near the connecting post 220, and the other is arranged at the end of the cover 210 away from the connecting post 220 and located on the right side of the socket 110; this distribution can maximize the function of the fixing posts 240 and the fixing holes 140 so that the entire surface of the cover 210 can be firmly attached to the bottom of the mounting groove 120.

[0052] Of course, the number and distribution of the fixing posts 240 and fixing holes 140 can be adjusted appropriately according to the actual situation, and this article does not impose specific limitations.

[0053] In one possible embodiment, the sidewall of the mounting groove 120 away from the connecting hole 130 is an arc-shaped structure, and the edge of the cover 210 away from the connecting post 220 is set as a smooth arc surface that matches the edge of the mounting groove 120.

[0054] Furthermore, such as Figures 2 to 5 As shown, in order to facilitate the user to easily open the waterproof cover 200 to insert or remove the TF card 02 when the waterproof cover 200 is fully engaged with the mounting slot 120, the lower side of the end of the cover body 210 away from the connecting post 220 is made into a smooth arc surface. At the same time, the corresponding position of the mounting slot 120 is also treated accordingly. This setting can ensure that the user can easily lift the cover body 210 after the waterproof cover 200 is fully engaged with the mounting slot 120.

[0055] In one possible embodiment, the waterproof cover 200 is made of flexible silicone material.

[0056] Understandably, silicone possesses excellent overall performance and is a flexible material. The waterproof cover 200, made of silicone, allows for overall deformation and recovery. This makes it easier for users to open and close the cover, facilitating the insertion and removal of the TF card 02. Furthermore, the silicone material allows for a smoother interference fit with the mounting slot 120. Of course, the waterproof cover 200 can also be made of other flexible materials; this article does not specify a particular material.

[0057] In one possible embodiment, the waterproof cover 200 is a one-piece structure.

[0058] Understandably, the one-piece structure of the waterproof cover 200 not only enhances its overall strength but also reduces its manufacturing costs. The waterproof cover 200 can be directly processed and molded by injection molding; moreover, the one-piece structure of the waterproof cover 200 also facilitates its subsequent assembly.

[0059] In summary, this application provides a sealed structure for a TF card. The board containing the TF card slot 01 is fixed to the inner wall of the housing 100 by screws. At this time, the TF card 02 can be inserted into the TF card slot 01 through the slot 110 on the housing 100. The connecting post 220 on the silicone waterproof cover 200 passes through the connecting hole 130 on the housing 100. Then, glue is applied to the contact position between the stop protrusion 230 inside the housing 100 and the connecting post 220 to fix it. At this time, the cover body 210 of the silicone waterproof cover 200 can be lifted and closed. When it is necessary to insert the TF card 02, lift the silicone waterproof cover 200, insert the TF card 02, and then close the silicone waterproof cover 200. When it is necessary to remove the TF card 02, lift the silicone waterproof cover 200, pull out the TF card 02, and then close the silicone waterproof cover 200. The fixing post 240 and the fixing hole 140, as well as the joint between the silicone waterproof cover 200 and the side of the housing 100, adopt an interference fit. This can fix the silicone waterproof cover 200 and the housing 100 so that they are not easy to fall off, and also achieve a sealing and waterproof effect.

[0060] This article also provides an infrared low-light night vision device, which includes the sealed structure of the TF card mentioned above; therefore, the infrared low-light night vision device also possesses all the beneficial effects of the sealed structure of the TF card mentioned above.
