[0008] Preferably, the mounting frame has a through groove at its upper end, and the top of the rotating shaft is movably connected through the through groove.

[0009] Preferably, an elastic telescopic rod A is fixedly connected to the back of the mounting frame, and the other end of the elastic telescopic rod A is fixedly connected to an L-shaped rod.

[0010] Preferably, a heat dissipation assembly is mounted on the side of the chassis.

[0016] The advantages of this application are: (1) This application achieves rapid, precise, and multi-dimensional stable installation of computer motherboards. A single "pull-release" action triggers the synergistic effect of lateral positioning, front clamping, and back suction. The lateral V-shaped bar mechanism can adapt to the slight dimensional deviations of the motherboard, ensuring a tight fit with the mounting frame; the upper roller then applies flexible longitudinal pressure; simultaneously, this movement is ultimately converted into negative pressure suction of the vacuum suction cup via a cam. This mechanical force transmission chain transforms manual operation into multi-degree-of-freedom automatic clamping and fixing, fundamentally eliminating the shaking of the motherboard caused by poor contact or vibration, and achieving highly reliable tool-free installation.

[0017] (2) This application adds a heat dissipation component, which effectively improves the heat dissipation effect of the computer motherboard. The rotation of the cooling fan and blades not only enhances air circulation but also cleans the dust on the cooling fan, avoiding the risk of poor heat dissipation. In particular, the design of the lifting plate, horizontal slot, and linkage shaft ensures that the cooling fan can be adjusted according to the status of the motherboard, further improving the heat dissipation efficiency. Through this added function, Embodiment 2 can effectively reduce the operating temperature of the motherboard and ensure the stable operation of the computer system under high load.

[0018] (3) By introducing a deceleration protection component, this application effectively avoids violent collisions during the installation or disassembly of the motherboard, protecting it from damage. Through the design of the deceleration pad, deceleration ring, and elastic telescopic rod B, when the positioning plate moves too fast, friction slows its movement, ensuring smoother contact between the positioning wheel and the motherboard. Furthermore, the symmetrical layout of the elastic telescopic rod B enhances overall stability, making the entire deceleration system operate more smoothly and reliably, thereby improving the safety and durability of the device and providing a safer and more efficient operating experience for the installation and disassembly of the motherboard.

[0027] Example 1, please refer to Figure 1 - Figure 8 This embodiment provides a computer motherboard mounting device to prevent shaking, including: a chassis 1; a side panel 2, the side panel 2 being mounted on the side of the chassis 1; and an opening on the back of the mounting frame 31. An internal mounting frame 31 is fixedly connected to the chassis 1. A sliding groove 32 is provided on the inner side of the mounting frame 31. A positioning plate 33 is slidably connected inside the sliding groove 32. An installation opening 34 is provided on one side of the positioning plate 33. A rotating shaft 35 is rotatably connected to the inner side of the installation opening 34. A V-shaped rod 36 is fixedly fitted on the outer wall of the rotating shaft 35. Positioning wheels A37 and B38 are respectively provided at both ends of the V-shaped rod 36. A U-shaped rod 39 slides through the upper side of the mounting frame 31. A slanted groove 310 is provided in the middle of the positioning plate 33. A sliding shaft 311 is rotatably connected to one end of the U-shaped rod 39. An installation plate 312 is fixedly connected to the other end of the U-shaped rod 39. A roller 313 is provided at the bottom of the installation plate 312. The back of the mounting frame 31 is fixedly connected to... A mounting bracket 316 is attached, and a pressure chamber 317 is fixedly connected to the middle of the mounting bracket 316. A suction cup 318 is fitted to the front end of the pressure chamber 317. A piston 319 is slidably connected inside the pressure chamber 317. A connecting rod 320 is fixedly connected to the outer wall of the piston 319. An L-shaped rod 315 is fixedly connected to the other end of the connecting rod 320. A connecting shaft 321 is fixedly connected to the front end of the L-shaped rod 315. A cross plate 323 is fixedly connected to the other end of the connecting shaft 321. A cam block 322 is fixedly connected to the bottom of the rotating shaft 35. A fixing block 324 is fixedly connected to the inner wall of the mounting frame 31. A pull rod 325 slides through the middle of the fixing block 324. A spring A326 is fixedly connected between the fixing block 324 and the positioning plate 33.

[0028] A fixing ring 328 is fixedly sleeved on the outer wall of the rotating shaft 35. A torsion spring 327 is fixedly connected to the upper end of the fixing ring 328. The upper end of the torsion spring 327 is fixedly connected to the inner wall of the mounting port 34.

[0029] The upper end of the mounting frame 31 has a through groove 329, and the top of the rotating shaft 35 is movably connected through the through groove 329. The top of the rotating shaft 35 can move or rotate flexibly in the through groove 329, thereby realizing the cooperation function of the two, while ensuring the stability and flexibility between the structures. This design not only facilitates installation and adjustment, but also ensures that the overall device operates more smoothly and efficiently.

[0030] A flexible telescopic rod A314 is fixedly connected to the back of the mounting frame 31. The other end of the flexible telescopic rod A314 is fixedly connected to the L-shaped rod 315. This connection method ensures that there will be no relative movement or loosening between the two. The flexible telescopic rod A314 plays a key role in the overall structure. One end of it is firmly attached to the back of the mounting frame 31, while the other end is tightly connected to the L-shaped rod 315, thereby achieving stable linkage between the two components.

[0031] When using the computer motherboard, first pull the lever 325 outward to make the positioning plate 33 slide outward inside the slide groove 32, and then place the computer motherboard inside the mounting frame 31. Then release the lever 325. Under the action of the spring A326, the positioning plate 33 will move towards the computer motherboard. Then the positioning wheel B38 at one end of the V-shaped rod 36 will first contact the side of the computer motherboard, thereby pushing the other side of the computer motherboard to fit against the inner wall of the mounting frame 31. When it is fully fitted, since the positioning plate 33 continues to be pushed and the positioning wheel B38 can no longer move, the rotating shaft 35 will be rotated through the V-shaped rod 36 until the positioning wheel A37 at the other end of the V-shaped rod 36 fits against the front of the computer motherboard. Simultaneously, since the sliding shaft 311 at one end of the C-shaped rod 39 is slidably connected in the inclined groove 310 opened on the outer wall of the positioning plate 33, when the positioning plate 33 moves inward, the inclined groove 310 will generate an oblique pushing force on the sliding shaft 311, thereby driving the C-shaped rod 39 to slide downward. During the downward movement of the C-shaped rod 39, the mounting plate 312 at its other end will also descend, and the roller 313 at the bottom of the mounting plate 312 will gradually approach the upper surface of the computer motherboard until it contacts the motherboard and applies a certain pressure, further limiting the longitudinal movement of the motherboard; At the same time, the rotation of the rotating shaft 35 will drive the cam block 322 at its bottom to rotate synchronously. During the rotation, the cam block 322 will contact the horizontal plate 323 and push the horizontal plate 323 to move backward. The horizontal plate 323 drives the L-shaped rod 315 to rotate backward through the connecting shaft 321. The L-shaped rod 315 then pulls the connecting rod 320 and the piston 319 to slide backward inside the pressure chamber 317, so that a negative pressure is formed inside the pressure chamber 317. Then, the suction cup 318 will be used to adsorb and fix the back of the computer motherboard. With the limiting effect of the positioning wheel A37, positioning wheel B38 and roller 313, the motherboard can be installed stably in multiple directions, effectively preventing the motherboard from shaking during use. When it is necessary to disassemble the motherboard, simply pull the lever 325 again to move the positioning plate 33 outward. The torsion spring 327 will drive the V-shaped rod 36 to reset, the cam block 322 will no longer apply pressure to the horizontal plate 323, and under the action of the elastic telescopic rod A314, the L-shaped rod 315 will rotate forward, the piston 319 will reset, and the suction cup 318 will release the motherboard, making it easy to remove the motherboard.

[0032] Example 2, please refer to Figure 1 - Figure 8Based on embodiment 1, a heat dissipation assembly 4 is mounted on the side of the chassis 1. The heat dissipation assembly 4 includes a rectangular frame 41, which is fixedly connected to the ventilation opening of the chassis 1. A cooling fan 42 and a filter plate 43 are arranged inside the rectangular frame 41. A mounting shaft 44 is rotatably connected to the inner wall of the ventilation opening. A blade plate 45 and a movable block 46 are fixedly sleeved on the outer wall of the mounting shaft 44. A linkage shaft 47 is fixedly connected to the outer wall of the movable block 46. A connecting plate 48 is fixedly connected to the outer wall of the C-shaped rod 39. A lifting plate 49 is fixedly connected to the bottom of the connecting plate 48. A transverse groove 410 is opened on the outer wall of the lifting plate 49.

[0033] The inner wall of the chassis 1 is provided with a vertical groove 411. One side of the lifting plate 49 is slidably connected to the inside of the vertical groove 411. This sliding connection design allows the lifting plate 49 to move smoothly up and down along the vertical groove 411, thereby realizing its predetermined function and operation requirements.

[0034] The outer wall of the linkage shaft 47 away from the movable block 46 is slidably connected to the inner wall of the transverse groove 410. This sliding connection allows the linkage shaft 47 to move flexibly inside the transverse groove 410 while ensuring a tight fit between the two, thereby ensuring the stability and reliability of the entire structure during operation. The sliding fit between the linkage shaft 47 and the inner wall of the transverse groove 410 also effectively reduces friction and improves the smoothness of overall operation.

[0035] In use, when the C-shaped rod 39 descends, the position of the motherboard surface is lower. Therefore, the C-shaped rod 39 will drive the connecting plate 48 to move down synchronously, and the connecting plate 48 will push the lifting plate 49 to slide down along the vertical groove 411. During the downward movement of the lifting plate 49, the horizontal groove 410 on its outer wall will exert a force on the linkage shaft 47. Since the linkage shaft 47 is fixed on the movable block 46, and the movable block 46 is sleeved on the outer wall of the mounting shaft 44, the linkage shaft 47 will drive the mounting shaft 44 to rotate, thereby causing the blades 45 on the mounting shaft 44 to rotate, changing the airflow angle and directing the airflow that was originally blown into the chassis to the motherboard surface, enhancing the heat dissipation effect on the core components of the motherboard. At the same time, the rotation of the blades 45 can also clean the dust accumulated on the surface of the filter plate 43 to a certain extent, preventing dust blockage from affecting the airflow of the cooling fan 42. When the motherboard is disassembled, the convex rod 39 rises, causing the lifting plate 49 to move upward. The horizontal groove 410 causes the mounting shaft 44 to rotate in the opposite direction through the linkage shaft 47, and the blade plate 45 returns to the initial angle, ensuring the stability of the overall heat dissipation airflow inside the chassis.

[0036] Example 3, please refer to Figure 1 - Figure 8Based on Embodiment 1, a deceleration protection component 5 is assembled on the inner side of the mounting frame 31. The deceleration protection component 5 includes a mounting base 51, which is fixedly connected to the inner side of the mounting frame 31. A rotating rod 52 is rotatably connected to the inner wall of the mounting base 51. A guide wheel 53 is fixedly sleeved on the outer wall of the rotating rod 52. A connecting rope 54 is wound around the outer wall of the guide wheel 53. One end of the connecting rope 54 is fixedly connected to the positioning plate 33, and the other end of the connecting rope 54 is fixedly connected to a counterweight 55. One end of the rotating rod 52 rotatably passes through one side of the mounting base 51, and an elastic telescopic rod B56 is fixedly connected to the outer wall of the rotating rod 52. A deceleration plate 57 is fixedly connected to the other end of the elastic telescopic rod B56. A deceleration ring 58 is fixedly connected to the front of the mounting frame 31.

[0037] The speed reducer 57 is located inside the speed reducer ring 58, and the speed reducer 57 is set to be arc-shaped and consistent with the curvature of the speed reducer ring 58. This arc-shaped design allows it to perfectly match the curvature of the speed reducer ring 58 and maintain the same curvature. This structural design not only ensures a tight fit between the two, but also effectively reduces the friction or impact that may occur during the movement, thereby improving the overall stability and efficiency of the operation.

[0038] Two flexible telescopic rods B56 and two speed reducers 57 are symmetrically distributed. This design ensures uniform force distribution during use and improves the overall structural stability and reliability. This symmetrical layout not only enhances the functionality of the device but also optimizes its operating efficiency, thus better meeting practical application needs.

[0039] When in use, the lever 325 needs to be slowly pulled forward by hand when released. If released suddenly, the positioning wheel B38 may damage the main board. Therefore, when the positioning plate 33 moves rapidly towards the main board under the elastic force of the spring A326, the positioning plate 33 will pull the guide wheel 53 to rotate through the connecting rope 54. The guide wheel 53 drives the rotating rod 52 to rotate synchronously, and the rotating rod 52 causes the elastic telescopic rod B56 to rotate accordingly. Since the other end of the elastic telescopic rod B56 is connected to the deceleration plate 57, and the deceleration plate 57 is located inside the deceleration ring 58, if the rotation speed of the rotating rod 52 is too fast, the elastic telescopic rod B56 will extend outward under the action of centrifugal force, causing the deceleration plate 57 to come into close contact with the inner wall of the deceleration ring 58. The friction between the two will hinder the rotation of the rotating rod 52, thereby slowing down the moving speed of the positioning plate 33 and preventing the positioning wheel B38 from colliding violently with the main board. As the moving speed of the positioning plate 33 gradually decreases, the centrifugal force on the elastic telescopic rod B56 decreases, and it contracts under its own elasticity. The deceleration plate 57 separates from the deceleration ring 58, allowing the positioning plate 33 to continue moving smoothly until it is in contact with the main board. When the main board is removed by pulling the pull rod 325, the positioning plate 33 moves outward. Under the action of gravity, the counterweight 55 pulls the guide wheel 53 to rotate in the opposite direction through the connecting rope 54. At this time, the rotation speed of the rotating rod 52 is relatively slow, and the elastic telescopic rod B56 will not cause the deceleration plate 57 to contact the deceleration ring 58, ensuring that the positioning plate 33 can be smoothly reset, facilitating the removal of the main board.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
