Description

Technical Field

[0001] This invention relates to the field of computer technology, specifically to a computer motherboard resistant to electromagnetic interference. Background Technology

[0002] The motherboard, also called the mainboard, system board, or motherboard, is one of the most basic and important components of a computer. A motherboard is generally a rectangular circuit board on which the main circuitry of the computer is installed. It typically includes components such as a BIOS chip, I / O control chip, keyboard and front panel control switch interfaces, indicator light connectors, expansion slots, and DC power supply connectors for the motherboard and expansion cards.

[0003] Patent publication number CN212906173U discloses a computer motherboard structure that facilitates testing. The structure includes a base plate with a mounting slot. A slot door is rotatably connected to the mounting slot via a damping shaft. Multiple circuit boards are housed within the mounting slot, each with multiple sockets and connecting blocks. Each connecting block has multiple signal lines. The base plate has multiple openings, and a cavity is formed in the upper wall of the base plate. A circuit receiving board that mates with the signal lines is located within the cavity. A fixing mechanism for securing the connecting blocks is also located within the cavity. This fixing mechanism includes an elastic mechanism to accommodate connecting blocks of varying thicknesses. A transmission mechanism providing power to the fixing mechanism is located on the right side of the base plate. This patented structure is reasonable, allowing for the removal of specific modules for testing when the computer motherboard malfunctions, thus avoiding the need to disassemble the entire motherboard.

[0004] Currently, motherboards on the market still have the following problems: During use, electromagnetic interference can cause the motherboard components to display a red light error, preventing the user from turning on the computer or causing the computer to shut down with a blue screen while working, affecting the user's production and life. Therefore, it is necessary to design a computer motherboard that can resist electromagnetic interference. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a computer motherboard resistant to electromagnetic interference, solving the problem mentioned in the background art where electromagnetic interference causes red LED errors on the motherboard components, preventing the user from booting up or causing the computer to crash with a blue screen during work, thus affecting the user's work and life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a computer motherboard resistant to electromagnetic interference, comprising a main body, wherein an electromagnetic interference resistant device, a heat dissipation device, and a winding device are fixed on the front side of the main body. The electromagnetic interference resistant device includes an electromagnetic interference shield, studs, and washers. The electromagnetic interference shield is disposed on the upper part of the front side of the main body, the studs are threadedly connected to the back side of the electromagnetic interference shield, the washers are fixed to the back side of the main body by springs, the studs penetrate the bottom of the electromagnetic interference shield, the studs penetrate the main body, and the studs penetrate the washers. The electromagnetic interference shield is fixed to the front side of the main body by the studs, and the main body is fixed inside the chassis by the studs. The washers and springs can reduce the vibration of the main body inside the chassis, and at the same time, can also reduce the loosening of the studs caused by vibration, so that the electromagnetic interference shield can be firmly fixed to the front side of the main body, thereby preventing electromagnetic interference to the operation of the main body's components.

[0007] Preferably, the heat dissipation device includes a shaped rod, a limiting ring, a square frame, and an eccentric shaft. The eccentric shaft is fixed to the fan shaft center by a cylinder. When the internal fan of the chassis and the main body is powered on, the main body fan drives the eccentric shaft to rotate. The inner wall of the square frame is slidably mounted on the side of the eccentric shaft, and the eccentric shaft drives the square frame to push and pull. The end of the shaped rod near the fan is fixed to the outer wall of the square frame, and the square frame drives the shaped rod to push and pull. The limiting ring is fixed to the top surface of the anti-electromagnetic shield, and the outer wall of the shaped rod is slidably connected to the inner wall of the limiting ring. The heat dissipation device also includes fins, connecting rods, a square box, and an inclined plate. The inclined plate is fixed inside the square box, and the front of the inclined plate... A semi-circular groove is provided. The end of the irregular rod away from the fan is slidably connected to the groove on the front of the inclined plate. The irregular rod slides on the surface of the inclined plate, causing the inclined plate to swing left and right. The inclined plate drives the square box to swing left and right. The fins are hinged to the upper part of the back of the main body. The connecting rod is hinged to the top surface of the fins. The square box is fixed to the end of the connecting rod near the irregular rod. The square box drives the connecting rod to swing left and right. The connecting rod drives the fins to swing left and right. The swing of the fins allows the airflow from the chassis fan to enter the back of the main body in a regular manner, thereby helping the main body to dissipate heat better. At the same time, the presence of the built-in fan also helps to dissipate heat inside the electromagnetic shield.

[0008] Preferably, the winding device includes a nut, a rotating shaft, a roller, a winding clamp, and a base. The two bases are fixed to the back of the main body, and the rotating shaft is rotatably connected between the two bases. During the installation of the main unit, the rotating shaft can be rotated by tightening the nut. The nut is fixedly connected to the bottom of the rotating shaft. The inner wall of the roller is fixed to the outer wall of the rotating shaft, and the rotating shaft drives the roller to rotate. The winding clamp is fixed to the upper part of the outer wall of the roller, and the roller drives the winding clamp to rotate. By fixing one end of the power cord to the winding clamp, the power cord can be wound on the surface of the roller, saving the time of manual winding.

[0009] Preferably, the winding device further includes a second rotating shaft, a screw, a shifter, and a second base. Two bases are fixed to the back of the main body. The second rotating shaft is rotatably connected between the two bases. The bottoms of the first and second rotating shafts are connected by a track drive. The first rotating shaft drives the second rotating shaft to rotate via the track. The inner wall of the screw is fixed to the outer wall of the second rotating shaft. The second rotating shaft drives the screw to rotate. The shifter is threadedly connected to the outer wall of the screw. The screw drives the threads on its surface to rotate. The shifter is slidably connected to the back of the main body. The rotation of the screw causes the shifter to move downward. By passing the power cord through the shifter, the shifter drives the power cord to move downward, so that the power cord can automatically wind downward at a uniform speed when the winding clamp rotates, thereby achieving the purpose of automatic winding. This makes the wiring more neat and tidy during the installation of the main unit, and at the same time prevents electromagnetic interference caused by messy wires. This avoids electromagnetic interference from the source.

[0010] Preferably, the winding device further includes a vertical rod and a wiping plate. One end of the vertical rod is fixed to the bottom surface of the fins. After the machine is powered on, the fins will swing left and right, thereby driving the vertical rod to make a semi-arc motion. One side of the wiping plate is fixed to the outer wall of the vertical rod. The vertical rod drives the wiping plate to make a semi-arc motion. The roller is located on the other side of the wiping plate's movement trajectory. The wiping plate periodically cleans and wipes the winding wire on the roller surface, preventing the wire from accumulating heat due to long-term use, which would shorten its service life, and also avoiding the risk of fire.

[0011] This invention provides a computer motherboard that is resistant to electromagnetic interference. It has the following beneficial effects:

[0012] (1) The present invention uses an anti-electromagnetic device to make the electromagnetic shield, studs and washers work together. The anti-electromagnetic shield is fixed to the front of the main body by the studs, and the main body is fixed inside the chassis by the studs. The washers and springs can reduce the vibration of the main body inside the chassis. At the same time, they can also reduce the loosening of the studs caused by vibration, so that the anti-electromagnetic shield can be firmly fixed to the front of the main body, thereby preventing electromagnetic interference to the operation of the main body's components.

[0013] (2) The present invention, through the arrangement of the heat dissipation device, enables the irregular rod, limiting ring, square frame, eccentric shaft, fins, connecting rod, square box and inclined plate to cooperate. The oscillation of the fins allows the airflow from the chassis fan to enter the back of the main body in a regular manner, thereby helping the main body to dissipate heat better. At the same time, the presence of the built-in fan also helps to dissipate heat inside the anti-electromagnetic shield.

[0014] (3) The present invention, through the setting of the winding device, enables the nut, rotating shaft one, roller, winding clamp and base one to cooperate. The roller drives the winding clamp to rotate, fixing one end of the power cord to the winding clamp, so that the power cord can be wound on the surface of the roller, saving the time of manual winding and routing; at the same time, the rotating shaft two, screw, shifter and base two cooperate, and when the screw rotates, the shifter moves downward. By passing the power cord through the shifter, the shifter drives the power cord to move downward, so that the power cord can automatically wind downward at a uniform speed when the winding clamp rotates, thereby achieving the purpose of automatic winding, making the wiring more beautiful and neat when the main unit is installed, and preventing electromagnetic interference caused by messy wires. After the machine is powered on, the vertical rod and the wiping plate cooperate to make the wiping plate periodically clean and wipe the winding wire on the surface of the roller, preventing the wire from accumulating dust and causing heat accumulation due to long-term use, which would shorten the service life, and also avoiding the risk of fire.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Please see Figure 1-8 This invention provides a technical solution: a computer motherboard resistant to electromagnetic interference, comprising a main body 1. An electromagnetic interference shield 2, a heat dissipation device 3, and a winding device 4 are fixed to the front of the main body 1. The electromagnetic interference shield 2 includes an electromagnetic interference shield 21, a stud 22, and a washer 23. The electromagnetic interference shield 21 is disposed on the upper part of the front of the main body 1. The stud 22 is slidably connected to the back of the electromagnetic interference shield 21. The front of the washer 23 is fixed to the back of the main body 1 by a spring. The stud 22 penetrates the bottom of the electromagnetic interference shield 21, penetrates the main body 1, and penetrates the washer 23. The stud 22 fixes the electromagnetic interference shield 21 to the front of the main body 1, and then fixes the main body 1 inside the chassis. The washer 23 and the spring can reduce the vibration of the main body 1 inside the chassis, and also reduce the loosening of the stud 22 due to vibration, so that the electromagnetic interference shield 21 can be firmly fixed to the front of the main body 1, achieving the purpose of preventing electromagnetic interference to the operation of the components of the main body 1.

[0026] The heat dissipation device 3 includes a shaped rod 34, a limiting ring 36, a square frame 37, and an eccentric shaft 38. The eccentric shaft 38 is fixed to the fan shaft center by a cylinder. When the fan inside the chassis and the main body 1 is powered on, the main body 1's built-in fan drives the eccentric shaft 38 to rotate. The inner wall of the square frame 37 is slidably mounted on the side of the eccentric shaft 38, and the eccentric shaft 38 drives the square frame 37 to push and pull. The end of the shaped rod 34 near the fan is fixed to the outer wall of the square frame 37, and the square frame 37 drives the shaped rod 34 to push and pull. The limiting ring 36 is fixed to the top surface of the anti-electromagnetic shield 21, and the outer wall of the shaped rod 34 is slidably connected to the inner wall of the limiting ring 36. The heat dissipation device 3 also includes fins 31, a connecting rod 32, a square box 33, and a sloping plate 35. The sloping plate 35 is fixed inside the square box 33, and the front of the sloping plate 35 is open. A semi-circular groove is provided, and the end of the irregular rod 34 away from the fan is slidably connected to the groove on the front of the inclined plate 35. The irregular rod 34 slides on the surface of the inclined plate 35, thereby causing the inclined plate 35 to swing left and right. The inclined plate 35 drives the square box 33 to swing left and right. The fin 31 is hinged to the upper part of the back of the main body 1, and the connecting rod 32 is hinged to the top surface of the fin 31. The square box 33 is fixed to the end of the connecting rod 32 near the irregular rod 34. The square box 33 drives the connecting rod 32 to swing left and right, and the connecting rod 32 drives the fin 31 to swing left and right. The swing of the fin 31 allows the airflow from the chassis fan to enter the back of the main body 1 in a regular manner, thereby helping the main body 1 to dissipate heat better. At the same time, the presence of the built-in fan also helps to dissipate heat inside the electromagnetic shield 21.

[0027] The winding device 4 includes a nut 47, a rotating shaft 43, a roller 45, a winding clamp 410, and a base 411. The two bases 411 are fixed to the back of the main body 1. The rotating shaft 43 is rotatably connected between the two bases 411. During the installation of the main unit, the rotating shaft 43 can be rotated by turning the nut 47. The nut 47 is fixed to the bottom of the rotating shaft 43. The inner wall of the roller 45 is fixed to the outer wall of the rotating shaft 43. The rotating shaft 43 drives the roller 45 to rotate. The winding clamp 410 is fixed to the upper part of the outer wall of the roller 45. The roller 45 drives the winding clamp 410 to rotate. By fixing one end of the power cord to the winding clamp 410, the power cord can be wound on the surface of the roller 45, saving the time of manual winding.

[0028] The winding device 4 also includes a second rotating shaft 44, a screw 46, a shifter 49, and a second base 412. Two bases 412 are fixed to the back of the main body 1. The second rotating shaft 44 is rotatably connected between the two bases 412. The bottom of the first rotating shaft 43 and the second rotating shaft 44 are connected via a track drive. The first rotating shaft 43 drives the second rotating shaft 44 to rotate via the track. The inner wall of the screw 46 is fixed to the outer wall of the second rotating shaft 44. The second rotating shaft 44 drives the screw 46 to rotate. The shifter 49 is threadedly connected to the outer wall of the screw 46. The screw 46 drives... The screw 46 rotates, and the shifter 49 is slidably connected to the back of the main body 1. The screw 46 rotates, causing the shifter 49 to move downward. By passing the power cord through the shifter 49, the shifter 49 drives the power cord to move downward, so that the power cord can automatically wind downward at a uniform speed when the winding clamp 410 rotates, thereby achieving the purpose of automatic winding. This makes the wiring more beautiful and neat when the host is installed, and at the same time prevents the generation of magnetism due to messy wires, thus avoiding electromagnetic interference from the source.

[0029] The winding device 4 also includes a vertical rod 41 and a wiping plate 42. One end of the vertical rod 41 is fixed to the bottom surface of the fin 31. After the machine is powered on, the fin 31 will swing left and right, thereby driving the vertical rod 41 to make a semi-arc motion. One side of the wiping plate 42 is fixed to the outer wall of the vertical rod 41. The vertical rod 41 drives the wiping plate 42 to make a semi-arc motion. The roller 45 is located on the other side of the movement trajectory of the wiping plate 42. The wiping plate 42 periodically cleans and wipes the winding wire on the surface of the roller 45 to prevent the wire from accumulating heat due to long-term use, which would shorten its service life, and also avoid the risk of fire.

[0030] In use, the electromagnetic shield 21 is fixed to the front of the main body 1 by the stud 22, and the main body 1 is fixed inside the chassis by the stud 22. The washer 23 and the spring can reduce the vibration of the main body 1 inside the chassis. At the same time, they can also reduce the loosening of the stud 22 due to vibration, so that the electromagnetic shield 21 can be firmly fixed to the front of the main body 1, thereby preventing electromagnetic interference to the operation of the components of the main body 1.

[0031] Meanwhile, when the fan inside the chassis and the main body 1 is powered on, the fan drives the eccentric shaft 38 to rotate. The eccentric shaft 38 drives the square frame 37 to push and pull. The square frame 37 drives the irregular rod 34 to push and pull. The irregular rod 34 slides on the surface of the inclined plate 35, causing the inclined plate 35 to swing left and right. The inclined plate 35 drives the square box 33 to swing left and right. The square box 33 drives the connecting rod 32 to swing left and right. The connecting rod 32 drives the fins 31 to swing left and right. The swing of the fins 31 allows the airflow from the chassis fan to enter the back of the main body 1 in a regular manner, thereby helping the main body 1 to dissipate heat better. At the same time, the presence of the built-in fan also helps to dissipate heat inside the anti-electromagnetic shield 21.

[0032] During the main unit installation phase, tightening nut 47 rotates shaft 43, which in turn rotates roller 45. Roller 45 then rotates winding clamp 410. By fixing one end of the power cord to winding clamp 410, the power cord can be wound around the surface of roller 45, saving time compared to manual winding. Simultaneously, shaft 43 drives shaft 44 via a track, which in turn rotates screw 46. Screw 46 rotates its surface threads, causing shifter 49 to move downwards. By passing the power cord through shifter 49, shifter 49 moves the power cord downwards, thus... When the winding clamp 410 rotates, the power cord can automatically wind downwards at a uniform speed, thereby achieving the purpose of automatic winding. This makes the wiring more neat and tidy during the installation of the host machine, and at the same time prevents electromagnetic interference caused by messy wires. After the chassis is powered on, the fin 31 will swing left and right, thereby driving the vertical rod 41 to make a semi-circular movement. The vertical rod 41 drives the wiping plate 42 to make a semi-circular movement. The wiping plate 42 periodically cleans and wipes the winding wire on the surface of the roller 45, preventing the wire from accumulating heat due to long-term use, which would shorten its service life, and also avoiding the risk of fire.
