[0031] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0032] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.
[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0034] like Figures 1 to 6 As shown, this utility model embodiment provides a TV set-top box with dustproof function, including a housing 1, a circuit board 2, a tail cover 3, a ventilation dustproof cover 4, a USB interface plug 5, and a video interface plug. The housing 1 has a receiving chamber 10, and the circuit board 2 is disposed in the receiving chamber 10. The first side wall of the circuit board 2 is provided with a plurality of video interfaces, and the second side wall of the circuit board 2 is provided with a plurality of USB interfaces 22. The USB interface plug 5 and the video interface plug are respectively detachably disposed on the side wall of the housing 1. The USB interface plug 5 is used to close the USB interface 22, and the video interface plug is used to close the USB interface 22. Since the USB interface and video interface are usually exposed on the side wall of the housing 1, if they are not used for a long time, dust, moisture or foreign objects are easily accumulated, which will affect the conductivity of the interface metal contacts. Therefore, by setting the detachable USB interface plug 5 and video interface plug, the corresponding interface can be closed when not in use, thereby preventing external dust and moisture from entering the interface and protecting the normal use of the circuit board 2 and the interface components.
[0035] The tail cover plate 3 is detachably connected to the tail of the housing 1 via a snap fastener. The tail cover plate 3 has a perforated groove 30, and the ventilation dust cover 4 is embedded in the perforated groove 30. The ventilation dust cover 4 is used to prevent external dust from entering the accommodating chamber 10 inside the housing 1. The perforated groove 30 on the tail cover plate 3 provides a channel for air circulation between the inside and outside of the housing 1, thereby meeting the heat dissipation requirements of the TV set-top box during operation. The ventilation dust cover 4 is embedded in the perforated groove 30 and has filter holes 40. In this way, while ensuring smooth airflow, dust can be effectively blocked from entering the interior of the housing 1. When it is necessary to clean the accumulated dust on the ventilation dust cover 4, only the tail cover plate 3 needs to be removed, thus ensuring the heat dissipation effect of the set-top box while also taking into account the convenience of disassembly and cleaning of accumulated dust.
[0036] like Figure 2 and Figure 5 As shown, the USB interface plug 5 further includes a plug head 51, a bent connecting part 52, and a locking bolt 53. The plug head 51 is used to insert into the USB interface 22. The end of the bent connecting part 52 is provided with a through hole 520. The locking bolt 53 passes through the through hole 520 and is locked to the side wall of the housing 1. The plug head 51 can be inserted into the USB interface 22, and its shape and size match the USB interface 22, which can effectively seal the USB interface 22 and prevent dust or moisture from entering. The bent connecting part 52 and the locking bolt 53 make it easy to fix the USB interface plug 5 to the side wall of the housing 1, improving the ease of use of the USB interface plug 5.
[0037] Furthermore, the bent connecting part 52 is made of a flexible material, and the bent connecting part 52 and the plug head 51 are integrally formed. The flexible material of the bent connecting part 52 allows it to bend or deform appropriately when the plug head 51 is inserted into the USB interface 22, thereby sealing at different angles and improving the installation flexibility of the USB interface plug 5.
[0038] like Figure 1 and Figure 4 As shown, the video interface further includes an HDMI interface 211 and a DP interface 212, which are respectively located on the side wall of the housing 1. The video interface plug includes an HDMI interface plug 61 and a DP interface plug 62. The HDMI interface plug 61 is used to close the HDMI interface 211, and the DP interface plug 62 is used to close the DP interface 212. By providing the HDMI interface 211 and DP interface 212 on the side wall of the housing 1, the set-top box can flexibly select the audio and video output method according to different usage scenarios, thereby improving the applicability and expandability of the set-top box and meeting users' access needs for multiple display interfaces.
[0039] like Figure 6 As shown, the ventilation dust cover 4 is further provided with a limiting baffle 41 on its edge. The limiting baffle 41 is provided with a plurality of positioning holes 410. The tail cover plate 3 is provided with a positioning rod 31 that engages with the positioning holes 410. This arrangement not only improves the installation stability of the ventilation dust cover 4 and prevents it from loosening, but also improves the assembly efficiency between the ventilation dust cover 4 and the tail cover plate 3, making it easier to disassemble and clean the ventilation dust cover 4.
[0040] like Figure 4 and Figure 6 As shown, further, the tail cover plate 3 is provided with several positioning blocks 32 along its edge, and the tail of the housing 1 is provided with an opening 100. The edge of the opening 100 is provided with several slots 101 that are connected to the positioning blocks 32 by snap-fit. With this configuration, the user only needs to apply appropriate external force to make the positioning blocks 32 disengage from the slots 101, thereby removing the tail cover plate 3, which is convenient for later disassembly of the ventilation dust cover 4 to clean the internal dust.
[0041] like Figure 4 As shown, the housing 1 further includes a bottom shell 11 and an upper cover shell 12. The upper cover shell 12 is located above the bottom shell 11, and the upper cover shell 12 and the bottom shell 11 are detachably connected by a snap fastener. This split detachable mechanism allows the upper cover shell 12 to be easily removed to clean the internal dust, avoiding cumbersome tool operations, and effectively improving the assembly efficiency of the set-top box.
[0042] like Figure 4 As shown, the video interface and the USB interface 22 are respectively located on adjacent walls of the bottom shell 11. This reduces interference between the interfaces, avoids interference when plugging and unplugging cables, and improves the human-computer interaction experience of the TV set-top box.
[0043] like Figure 3 As shown, furthermore, the bottom of the base shell 11 is provided with a plurality of anti-slip pads 110, which can play an anti-slip role and effectively improve the placement stability of the set-top box.
[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
