Description

Technical Field

[0001] This utility model relates to the field of computer hardware technology, and in particular to a set-top box motherboard physical structure with optimized wiring layout. Background Technology

[0002] A set-top box is a device that connects a television set to an external signal source. Its working principle is essentially to receive, process, and convert signals, and finally transmit various audio and video content to the television for users to watch. Its core is signal flow and processing, and it is mainly used in home entertainment, industry services, and public information dissemination.

[0003] One optimized set-top box motherboard physical structure places the core chip in the center of the motherboard layout. For data lines and address lines with high signal timing requirements, equal-length wiring is used to ensure signal synchronization. However, set-top box motherboards have high integration and dense chip components. Even with optimized wiring, heat dissipation problems still occur if the heat dissipation path is not properly planned. Insufficient heat dissipation holes and improper heatsink placement also reduce heat dissipation efficiency. In existing technologies, the CPU and power module are centrally located with appropriate heat dissipation gaps around them to avoid obstruction by other components. Heatsinks are directly soldered to the bottom of the chip via metal pins to reduce interface thermal resistance. However, the heatsinks' temperature uniformity is insufficient, leading to increased temperature differences on the chip surface and affecting signal integrity. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a set-top box motherboard physical structure with optimized wiring layout, aiming to improve the problem of insufficient heat dissipation holes in the motherboard of the prior art, which reduces the heat dissipation effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a set-top box motherboard physical structure with optimized wiring layout, including a body 1 and a main board 4. A heat dissipation mechanism 2 is installed inside the main board 4 for heat dissipation. A dust removal mechanism 3 is provided on the top wall of the body 1 for dust removal. The heat dissipation mechanism 2 includes a micro motor 201, which is installed inside the main board 4. The output end of the micro motor 201 is fixedly connected to a first rotating shaft 202. The lower end of the first rotating shaft 202 is fixedly connected to a second rotating shaft 203. The left end of the second rotating shaft 203 is rotatably connected to a connecting rod 204. The front end of the connecting rod 204 is rotatably connected to the base 207. The front end of the base 207 is equipped with the second motor 205. The output end of the second motor 205 is fixedly connected to the axial flow fan 206. The upper and lower ends of the connecting rod 204 are equipped with toothed claws 210. The inside of the toothed claws 210 is fixedly connected to the spring 209. The left end of the spring 209 is equipped with a gear 208. The upper and lower ends of the gear 208 are respectively connected to the upper and lower ends of the toothed claws 210. The left end of the motherboard 4 is provided with a power interface slot 14. The right end of the motherboard 4 is equipped with a chip 13. The front end of the motherboard 4 is provided with a bracket 16. The bottom end of the body 1 is fixedly connected to the base 15.

[0032] Specifically, starting the micro motor 201 and motor 205 drives the rotating shaft 202 and rotating shaft 203 to start rotating. The connecting rod 204 and the pawl 210 connected to the rotating shaft 203, under the action of the rotation of the micro motor 201, convert the reciprocating oscillating motion of the power end into the pushing and pulling action of the pawl 210, thereby driving the pawl 210 to push the gear 208. With the help of the connecting rod 204, the gear 208 swings step by step. After the pawl 210 completes the swing, the spring 209 will pull it back to maintain contact with the gear 208. Under the action of the connecting rod 204, the base 207 moves left and right, synchronously driving the axial fan 206 to move left and right, promoting airflow, thereby removing the heat generated by the components on the main board 4 when they are working.

[0033] Reference Figure 1 , Figure 3 and Figure 5The dust removal mechanism 3 includes an electric cylinder 301, which is installed inside the body 1. The output end of the electric cylinder 301 is fixedly connected to a bracket 309. A filter screen 304 is installed inside the bracket 309. Limiting plates 306 are provided at both the front and rear ends of the filter screen 304. Guide rails 302 are fixedly connected at both the front and rear ends of the limiting plates 306. A slot 303 is provided at the upper end of the guide rail 302. A cylinder 305 is installed at the upper end of the slot 303. A slot box 307 is installed on the outer side of the guide rail 302. Brushes 308 are installed on the front and rear sides of the slot box 307. An audio connection slot 9 is provided at the right end of the trapezoidal slot 8. A card slot 10 is provided on the right side of the audio connection slot 9. A switch 11 is installed at the upper end of the card slot 10. A heat dissipation hole 12 is provided on the top of the body 1.

[0034] Specifically, after the electric cylinder 301 is turned on, the bracket 309 of the electric cylinder 301 will move left and right simultaneously with the guide rail 302. The brushes 308 at the front and rear ends of the slot box 307 are in a fixed state, while the slot 303 on the guide rail 302 facilitates the movement of the cylinder 305, which drives the filter screen 304, which is fixedly connected to the limit plate 306, to move synchronously. During the movement, the brushes 308 will come into contact with the filter screen 304 and clean the dust accumulated on the filter screen 304. The cleaned dust will fall directly into the slot box 307. When the machine body 1 runs for a long time, dust can easily accumulate at the heat dissipation holes 12. The brushes 308 and the moving design used in the dust removal mechanism 3 can effectively collect the dust, thereby achieving the dust removal effect.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Antennas 5 are fixedly connected to both the left and right ends of the body 1. An input interface slot 6 is provided on the left side of the front end of the body 1. A USB card slot 7 is provided on the right end of the input interface slot 6. A trapezoidal slot 8 is provided on the right end of the USB card slot 7.

[0036] Specifically, the antenna 5 at the front of the unit 1 is used to receive and send wireless signals, the trapezoidal slot 8 is a high-definition multimedia interface used to transmit high-definition audio and video signals, mainly connecting to TVs and monitors, outputting images and sound, ensuring audio and video synchronization, and is a commonly used interface for high-definition devices. The USB card slot 7 is used to connect storage devices such as USB flash drives to play local videos or programs.

[0037] Working principle: When the micro motor 201 and motor 205 are started, the rotating shaft 202 and rotating shaft 203 are driven to rotate. The connecting rod 204 and the toothed pawl 210 connected to the rotating shaft 203 are driven by the rotation of the micro motor 201, which converts the reciprocating oscillating motion of the power end into the pushing and pulling action of the toothed pawl 210. The toothed pawl 210 pushes the gear 208, which is driven to oscillate by the connecting rod 204, and drives the gear 208 to rotate step by step. After the toothed pawl 210 oscillates, the spring 209 pulls it back to its original position and maintains contact with the gear 208. Under the action of the connecting rod 204, the base 207 moves left and right, which drives the axial fan 206 to move left and right together, promotes air flow, and removes the heat generated by the components on the main board 4 during operation.

[0038] When the electric cylinder 301 is activated, the bracket 309 of the electric cylinder 301 and the guide rail 302 move left and right together. The brushes 308 at both ends of the card slot box 307 are fixed. The card slot 303 on the guide rail 302 facilitates the movement of the cylinder 305. At the same time, it drives the filter screen 304 fixedly connected to the limit plate 306 to move. During the movement, the brushes 308 contact the filter screen 304 and sweep away the dust that falls on the filter screen 304. The swept dust will directly enter the card slot box 307. When the machine body 1 is running for a long time, dust is easy to accumulate at the heat dissipation hole 12. The brushes 308 in the dust removal mechanism 3 and the moving design facilitate the collection of dust and achieve the dust removal effect.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
