Description

Technical Field

[0001] This utility model belongs to the field of TV stick technology, and in particular relates to a TV stick with an expansion interface. Background Technology

[0002] A TV stick is a USB-interface digital television receiver device, resembling a USB flash drive. It uses a built-in tuner and decoding chip to receive signals such as terrestrial waves (DVB-T / T2) or cable television (DVB-C), converting them into audio and video content that can be played on computers or smart devices. Users simply connect an antenna and install the accompanying software to watch clear, unencrypted channels for free, making it a convenient digital television solution.

[0003] Most existing TV sticks have sealed casings, which makes it inconvenient to connect peripherals or provide a more stable network. In addition, the sealed casings have poor heat dissipation. After the heating elements inside the TV stick have been working for a long time, they will become severely overheated, leading to signal demodulation errors or device restarts and poor performance. Therefore, based on actual usage, we have improved the above-mentioned existing technologies. Utility Model Content

The quick-release heat dissipation unit includes multiple sets of thermally conductive irregularly shaped adhesive sheets that are attached to the circuit board. A thermally conductive sealing plate is installed on the thermally conductive irregularly shaped adhesive sheets, and multiple sets of heat dissipation fins are connected to the side of the thermally conductive sealing plate away from the circuit board.

[0006] In a preferred embodiment of this utility model, a connecting wire is installed on the circuit board, the connecting wire passes through the TV stick housing, and a plug is provided on the connecting wire.

[0007] In a preferred embodiment of this utility model, two sets of soft straps are fixedly connected to the housing of the TV stick, and the two sets of soft straps are respectively connected to two sets of sealing rubber plugs.

[0008] In a preferred embodiment of the present invention, the quick-release heat dissipation part further includes side grooves formed at both ends of the upper opening, and two sets of upper handles are fixedly connected to the heat-conducting sealing plate, with the two sets of upper handles respectively located in the two sets of side grooves.

[0009] In a preferred embodiment of this utility model, a rotating rod is fixedly connected to each set of side grooves, and a rotating plate is rotatably connected to the rotating rod for limiting the upper handle.

[0010] In a preferred embodiment of this utility model, multiple sets of telescopic rods are fixedly connected to the inner wall of each set of side grooves, and a spring is sleeved on the outer wall of each set of telescopic rods for lifting the upper handle.

[0011] In a preferred embodiment of this utility model, the size of the thermally conductive sealing plate is equal to the size of the upper opening, and a sealing layer is provided between the thermally conductive sealing plate and the upper opening.

[0012] This utility model solves the defects existing in the background technology, and has the following beneficial effects: This utility model's TV stick features an expansion interface for easy connection to peripherals or to provide a more stable network. When the TV stick is not in use, a sealing rubber plug can be placed inside the expansion interface to prevent moisture and dust from entering the TV stick and affecting the connection.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0016] This embodiment provides a TV stick with an expansion interface 12, which facilitates the connection of peripherals or provides a more stable network. When the TV stick is not in use, the sealing rubber plug 14 can be placed inside the expansion interface 12 to prevent moisture and dust in the air from entering the TV stick and affecting the connection of the expansion interface 12. The multiple sets of thermally conductive irregularly shaped adhesive pieces 209 on the quick-release heat dissipation part 20 have a thermal conductivity function, which can conduct the heat generated by the heat-generating element inside the TV stick to the thermally conductive sealing plate 201. The multiple sets of heat dissipation fins 202 conduct the heat away, realizing the rapid heat dissipation of the TV stick. This prevents the TV stick from overheating after long-term use, which may lead to signal demodulation errors or device restarts. At the same time, after the rotating plate 206 is rotated, the elasticity of the telescopic rod 207 and the spring 208 will lift the upper handle 204, which can quickly push out the thermally conductive sealing plate 201, heat dissipation fins 202 and thermally conductive irregularly shaped adhesive pieces 209, making it easy to install, disassemble and maintain.

[0017] Combination Figures 1 to 4 As shown, the TV stick in this embodiment includes a TV stick housing 10, a circuit board 16 inside the TV stick housing 10, two sets of expansion interfaces 12 on the TV stick housing 10, and sealing rubber plugs 14 on the outer side of each of the two sets of expansion interfaces 12. The TV stick housing 10 has an upper opening 15, and a quick-release heat dissipation part 20 is provided inside the upper opening 15. The TV stick in this embodiment is an existing component, and the specific model and working principle are not described here. The expansion interface 12 is used to connect with peripherals. When the TV stick is not in use, the sealing rubber plugs 14 are plugged in the expansion interface 12 to prevent dust and moisture from entering the TV stick and to not affect the subsequent connection and use of the expansion interface 12.

[0018] In this embodiment, the quick-release heat dissipation part 20 includes multiple sets of thermally conductive irregularly shaped adhesive sheets 209 attached to the circuit board 16. A thermally conductive sealing plate 201 is installed on the thermally conductive irregularly shaped adhesive sheet 209, and multiple sets of heat dissipation fins 202 are connected to the side of the thermally conductive sealing plate 201 away from the circuit board 16. The thermally conductive sealing plate 201 is disposed in the upper opening 15 and seals it. The thermally conductive irregularly shaped adhesive sheet 209 has good thermal conductivity and can conduct the heat generated by the components on the circuit board 16 during operation to the thermally conductive sealing plate 201. The multiple sets of heat dissipation fins 202 then conduct the heat away, realizing the rapid heat dissipation of the TV stick and avoiding the TV stick from overheating after long-term use, which may lead to signal demodulation errors or device restart.

[0019] Combination Figure 1 , Figure 3 as well as Figure 4As shown, a connecting wire is installed on the circuit board 16 of this embodiment. The connecting wire passes through the TV stick housing 10, and a plug 11 is provided on the connecting wire. The plug 11 installed through the connecting wire can be connected to the device. Two sets of soft straps 13 are fixedly connected to the TV stick housing 10. The two sets of soft straps 13 are respectively connected to two sets of sealing rubber plugs 14. The soft straps 13 can place the sealing rubber plugs 14 on the TV stick housing 10 to prevent them from falling off, and do not affect the use of the sealing rubber plugs 14.

[0020] Furthermore, the quick-release heat dissipation part 20 of this embodiment also includes side grooves 203 formed at both ends of the upper opening 15. Two sets of upper handles 204 are fixedly connected to the heat-conducting sealing plate 201. The two sets of upper handles 204 are respectively located in the two sets of side grooves 203. A rotating rod 205 is fixedly connected to each set of side grooves 203, and a rotating plate 206 is rotatably connected to the rotating rod 205 for limiting the upper handle 204.

[0021] In this embodiment, multiple sets of telescopic rods 207 are fixedly connected to the inner wall of each set of side grooves 203, and springs 208 are sleeved on the outer wall of each set of telescopic rods 207 for lifting the upper handle 204; multiple sets of heat-conducting irregularly shaped bonding plates 209 and heat dissipation fins 202 are fixedly connected to the heat-conducting sealing plate 201. The rotation of the rotating rod 205 can cause the rotating plate 206 to adhere to the upper handle 204, fixing the heat-conducting sealing plate 201. At this time, the telescopic rods 207 and springs 208 are in a compressed state. When disassembly and maintenance are required, rotate the plate 206 to move it away from the top of the upper handle 204. The compressed telescopic rod 207 and spring 208 will spring out, causing the upper handle 204 to move upward. This allows the thermally conductive sealing plate 201, heat dissipation fins 202, and thermally conductive irregularly shaped adhesive sheet 209 to be pushed out for easy maintenance. The size of the thermally conductive sealing plate 201 is equal to the size of the upper opening 15, and a sealing layer is provided between the thermally conductive sealing plate 201 and the upper opening 15; the sealing layer plays a role in sealing and waterproofing.

[0022] In actual use, the TV stick in this embodiment can be used by connecting it to the device via plug 11. The expansion interface 12 can be connected to peripherals. When the TV stick is not in use, the sealing rubber plug 14 on the soft strap 13 blocks the expansion interface 12 to prevent dust and moisture from entering the TV stick without affecting the subsequent connection and use of the expansion interface 12. The thermally conductive irregularly shaped adhesive piece 209 of the quick-release heat dissipation part 20 has good thermal conductivity and can conduct the heat generated by the components on the circuit board 16 during operation to the thermally conductive sealing plate 20. On the top, multiple sets of heat dissipation fins 202 conduct heat away, achieving rapid heat dissipation of the TV stick. This prevents the TV stick from overheating after prolonged use, which could lead to signal demodulation errors or device restarts. When the TV stick needs maintenance, the rotating plate 206 on the rotating rod 205 rotates to move it away from the upper handle 204. At this time, the compressed telescopic rod 207 and spring 208 spring open, causing the upper handle 204 to move upward. This allows the thermally conductive sealing plate 201, heat dissipation fins 202, and thermally conductive irregular adhesive plate 209 to be pushed out for easy maintenance.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
