Description
Technical Field
[0001] This utility model relates to the field of audio and video driver motherboard technology, and in particular to an audio and video driver motherboard that is easy to install. Background Technology
[0002] Audio / video driver motherboards typically refer to the core circuit boards in computer motherboards or professional audio / video equipment used for audio and video signal processing and transmission.
[0003] The main function of an audio / video driver motherboard is to process and transmit audio and video signals, ensuring signal quality and stability. The role of the audio / video driver motherboard may vary in different application scenarios. In personal computers, the integrated sound card on the motherboard, or a separate sound card via PCIe or PCI interfaces, as well as integrated or separate graphics cards, can all be considered part of the driver motherboard that processes audio and video signals, responsible for handling internal and external audio and video signals. In professional audio / video equipment, such as broadcasting equipment, professional sound systems, and video surveillance systems, the driver motherboard may be a separate circuit board specifically responsible for the acquisition, processing, transmission, and output of audio and video signals.
[0004] In existing audio / video driver motherboard installation technologies, bolt holes are typically required at the four corners of the motherboard to secure it to the chassis or other support structure. However, during the fixing process, the bolts directly contact these bolt holes, resulting in significant direct pressure on the motherboard. This can potentially cause physical damage to the electronic components and circuit traces on the motherboard. Furthermore, because the pressure generated during bolt fixing is concentrated in a small area of the motherboard, this excessive local pressure can easily damage the motherboard, affecting its stability and lifespan. Therefore, this paper proposes an audio / video driver motherboard that is easier to install to overcome these shortcomings. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-install audio and video driver motherboard.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an easy-to-install audio / video driver motherboard, comprising a motherboard body, with reserved holes at the four corners of the motherboard body, a rubber layer contacting the outer side of the four corners of the motherboard body, a protective plate fixedly connected to the outer side of the rubber layer, a through hole longitudinally formed in the middle of the protective plate and the rubber layer, a first expansion cylinder slidably connected to the lower part of the inner side of the protective plate, a fixed cylinder fixedly connected to the top of the first expansion cylinder, an internal thread formed on the inner wall of the fixed cylinder, a second expansion cylinder fixedly connected to the top of the fixed cylinder, a bucket-shaped flexible plate fixedly connected to the top of the second expansion cylinder, and a fastening bolt spirally connected inside the fixed cylinder.
[0007] As a further description of the above technical solution: the inner wall of the reserved hole at the four corners of the motherboard body contacts the outer side of the fixing cylinder, and the outer side of the second expansion cylinder contacts the inner wall of the through hole at the top of the inner side of the protective plate. This can prevent the fastening bolt from directly contacting the reserved hole of the motherboard body, thereby reducing the direct pressure and potential physical damage to the motherboard body. This helps to protect the electronic components and circuit traces on the motherboard.
[0008] As a further description of the above technical solution: the number of the protective plates matches the number of reserved holes opened inside the motherboard body, and the protective plates wrap around the four outer corners of the protective plate body. The through holes opened inside the protective plates and rubber layers are perpendicular to the reserved holes, which can protect the four corners of the motherboard body and distribute the pressure generated when the fastening bolts are fixed evenly on the protective plates, rather than concentrating it in a small area of the motherboard body. This can reduce damage caused by excessive local pressure.
[0009] As a further description of the above technical solution: the diameter of the through hole opened inside the protective plate and the rubber layer matches the cross-sectional diameter of the first expansion cylinder and the second expansion cylinder, and the diameter of the reserved hole at the four corners inside the main body matches the cross-sectional diameter of the fixing cylinder. The cross-sectional diameter of the fixing cylinder is 1.2 times larger than the cross-sectional diameter of the first expansion cylinder and the second expansion cylinder, which allows the fixing cylinder to be inserted into the protective plate by applying pressure, so that the main body and the protective plate are pre-fixed, which facilitates the positioning of the fastening bolts.
[0010] As a further description of the above technical solution: the pitch of the internal thread on the inner wall of the fixed cylinder matches the surface pitch of the fastening bolt, and the cross-sectional diameter of the fixed cylinder matches the cross-sectional diameter of the fastening bolt. The length of the fixed cylinder is the same as the inner height of the guard plate, which allows the fixed cylinder to stay between the arc plate and the reserved hole of the main body, and it will not expand like the first expansion cylinder and the second expansion cylinder, thus avoiding the fastening bolt from directly contacting the reserved hole of the main body.
[0011] As a further description of the above technical solution: the bottom diameter of the bucket-shaped flexible plate matches the top diameter of the second expansion cylinder, and the top diameter of the bucket-shaped flexible plate matches the cross-sectional diameter of the fixed cylinder. The upper inner side of the bucket-shaped flexible plate contacts the top of the fastening bolt and is squeezed by the fastening bolt to deform downward. The bucket-shaped flexible plate can protect the top of the protective plate and prevent the fastening bolt from being tightened, which would cause the top of the fastening bolt to squeeze the protective plate and deform.
[0012] As a further description of the above technical solution: the height of the first expansion cylinder and the second expansion cylinder are consistent with the thickness of the upper and lower inner sides of the protective plate. The first expansion cylinder and the second expansion cylinder have hollowed-out grooves inside, which can be expanded by the insertion of fastening bolts, so that the first expansion cylinder and the second expansion cylinder expand outward, thereby achieving a stable effect between the protective plate and the main body.
[0013] This utility model has the following beneficial effects:
[0014] This utility model designs an easy-to-install audio / video driver motherboard. Through the design of the protective plate and the fixing cylinder, the device avoids direct contact between the fastening bolts and the reserved holes on the motherboard body, thereby reducing direct pressure and potential physical damage to the motherboard body. This helps protect the electronic components and circuit traces on the motherboard. Furthermore, the design of the fixing cylinder helps to evenly distribute the pressure generated when the fastening bolts are tightened onto the protective plate, rather than concentrating it in a small area on the motherboard body. This reduces damage caused by excessive local pressure. At the same time, since the protective plate can be locked outside the reserved holes, it provides a more stable support point for the motherboard body, reducing displacement of the motherboard body due to vibration or external forces after installation and improving overall stability.

[0021] Reference Figures 1 to 4This utility model provides an easy-to-install audio / video driver motherboard, including a motherboard body 1. Pre-drilled holes 11 are opened at the four corners of the motherboard body 1. The outer sides of the four corners of the motherboard body 1 are wrapped with rubber layers 5. A protective plate 2 is adhered to the outer side of the rubber layers 5 by adhesive. A through hole 6 is opened longitudinally between the protective plate 2 and the rubber layers 5. A first expansion cylinder 7 is inserted into the lower part of the protective plate 2. A fixing cylinder 8 is provided at the top of the first expansion cylinder 7. An internal thread 10 is opened on the inner wall of the fixing cylinder 8. A second expansion cylinder 9 is provided at the top of the fixing cylinder 8. A bucket-shaped flexible plate 3 is provided at the top of the second expansion cylinder 9. A fastening bolt 4 is passed through and spiraled inside the fixing cylinder 8. The inner wall of the pre-drilled holes 11 at the four corners of the motherboard body 1 contacts the outer side of the fixing cylinder 8. The outer side of the second expansion cylinder 9 contacts the inner wall of the through hole 6 at the upper part of the protective plate 2. This avoids the fastening bolt 4 directly contacting the pre-drilled holes 11 of the motherboard body 1, thereby reducing direct pressure and potential physical damage to the motherboard body 1. This helps protect the electronic components and circuit traces on the motherboard.
[0022] As a further implementation of the above technical solution: the number of protective plates 2 matches the number of reserved holes 11 opened inside the motherboard body 1, and the protective plates 2 wrap around the four outer corners of the protective plate 2 body. The through holes 6 opened inside the protective plates 2 and the rubber layer 5 are perpendicular to the reserved holes 11, which can protect the four corners of the motherboard body 1 and distribute the pressure generated when the fastening bolts 4 are fixed evenly on the protective plates 2, rather than concentrating it in a small area of the motherboard body 1. This can reduce damage caused by excessive local pressure.
[0023] As a further implementation of the above technical solution: the diameter of the through hole 6 opened inside the protective plate 2 and the rubber layer 5 matches the cross-sectional diameter of the first expansion cylinder 7 and the second expansion cylinder 9, and the diameter of the reserved hole 11 at the four corners inside the main body 1 matches the cross-sectional diameter of the fixing cylinder 8. The cross-sectional diameter of the fixing cylinder 8 is one and a half times larger than the cross-sectional diameter of the first expansion cylinder 7 and the second expansion cylinder 9, so that the fixing cylinder 8 can be inserted into the protective plate 2 by applying pressure, so that the main body 1 and the protective plate 2 are pre-fixed, which facilitates the positioning of the fastening bolt 4.
[0024] As a further implementation of the above technical solution: the pitch of the internal thread 10 on the inner wall of the fixing cylinder 8 matches the surface pitch of the fastening bolt 4, and the cross-sectional diameter of the fixing cylinder 8 matches the cross-sectional diameter of the fastening bolt 4. The length of the fixing cylinder 8 is the same as the inner height of the guard plate 2, so that the fixing cylinder 8 can stay between the arc plate and the reserved hole 11 of the main body 1, and will not expand like the first expansion cylinder 7 and the second expansion cylinder 9, thus avoiding the fastening bolt 4 from directly contacting the reserved hole 11 of the main body 1.
[0025] As a further implementation of the above technical solution: the bottom diameter of the bucket-shaped flexible plate 3 matches the top diameter of the second expansion cylinder 9, and the top diameter of the bucket-shaped flexible plate 3 matches the cross-sectional diameter of the fixed cylinder 8. The upper inner side of the bucket-shaped flexible plate 3 contacts the top of the fastening bolt 4 and is squeezed by the fastening bolt 4 to deform downward. The bucket-shaped flexible plate 3 can protect the top of the guard plate 2 and prevent the fastening bolt 4 from being tightened, which would cause the top of the fastening bolt 4 to squeeze the guard plate 2 and deform.
[0026] As a further implementation of the above technical solution: the height of the first expansion cylinder 7 and the second expansion cylinder 9 are consistent with the thickness of the upper and lower inner sides of the guard plate 2. The first expansion cylinder 7 and the second expansion cylinder 9 are provided with hollowed-out grooves inside, which can be expanded by the entry of the fastening bolt 4, so that the first expansion cylinder 7 and the second expansion cylinder 9 expand outward, thereby achieving a stable effect between the guard plate 2 and the main body 1.
[0027] Working principle:
[0028] When using this utility model, insert the four sets of protective plates 2 into the outer sides of the four corners of the main body 1. At this time, the rubber layer 5 on the inner side of the protective plate 2 is in contact with the surface of the four corners of the main body 1 until the through hole 6 opened inside the protective plate 2 and the rubber layer 5 is perpendicular to the reserved hole 11 opened inside the main body 1. Then, take out the bucket-shaped soft plate 3. The bottom of the bucket-shaped soft plate 3 is provided with a second expansion cylinder 9, a fixing cylinder 8 and a first expansion cylinder 7. Insert the first expansion cylinder 7 into the upper part of the protective plate 2 from top to bottom. Since the cross-sectional diameter of the first expansion cylinder 7 is the same as the diameter of the through hole 6, the first expansion cylinder 7 penetrates the upper part of the protective plate 2 without resistance. When the fixing cylinder 8 enters the protective plate 2, the cross-sectional diameter of the fixing cylinder 8 is larger than the cross-sectional diameter of the first expansion cylinder 7. When the fixing cylinder 8 enters the protective plate 2, it needs to apply downward pressure until the protective plate 2 enters the reserved hole 11 inside the main body 1. Then, the first expansion cylinder 7 enters the through hole 6 at the bottom of the protective plate 2. The second expansion cylinder 9 enters the through hole 6 at the top of the inner side of the protective plate 2, while the bucket-shaped flexible plate 3 is located at the top of the protective plate 2. After installation, the main body 1 can be connected to the equipment housing. Place the main body 1 in the set position, and the bottom of the second expansion cylinder 9 contacts the bolt connection point set inside the housing. Take out the fastening bolt 4 and insert the fastening bolt 4 from top to bottom into the bucket-shaped flexible plate 3. The bucket-shaped flexible plate 3 is deformed by the pressure of the fastening bolt 4. At this time, the fastening bolt 4 moves downward to the inner wall of the second expansion cylinder 9, and the second expansion cylinder 9 is also compressed and expands until the bottom end of the fastening bolt 4 contacts the internal thread 10 inside the fixed cylinder 8. Rotate the fastening bolt 4 to let the fastening bolt 4 continue to move downward in a spiral manner. During the movement, it squeezes the first expansion cylinder 7 outward. At this time, the protective plate 2 and the main body 1 are fixed. The fastening bolt 4 continues to rotate and move downward until the bolt connection point between the main body 1 and the housing is connected and fixed, which means the installation is complete.
