Description

Technical Field

[0001] This invention relates to the field of motherboard technology, specifically to an electronic data processing motherboard connection component and a motherboard. Background Technology

[0002] The motherboard, also called the motherboard, is installed inside the computer case and is one of the most basic and important components of a computer. It plays a crucial role in the entire computer system. The motherboard is the core of the computer hardware system and the largest printed circuit board in the case. The main function of the motherboard is to transmit various electronic signals, and some chips also handle preliminary processing of some peripheral data. All components in the computer case are connected through the motherboard, and the operation of system memory, storage devices, and other I / O devices during normal computer operation must be performed through the motherboard.

[0003] The motherboard uses an open architecture. Most motherboards have 6-15 expansion slots for connecting control cards (adapters) for PC peripherals. By replacing these cards, corresponding subsystems of the microcomputer can be partially upgraded, giving manufacturers and users greater flexibility in configuring their systems.

[0004] In existing technologies, plug-in peripherals are generally connected via slots such as PCIe and secured with clips. These clips engage with both ends of the slot and can rotate within a certain angle range. The peripherals have gold fingers arranged on the bottom, which are elongated. Installation requires a professional. However, with the increasing prevalence of computers, plug-in peripherals such as graphics cards and memory modules are frequently updated. Finding a professional to disassemble and install them is time-consuming. When installing plug-in peripherals, the force on both ends of the peripheral must be even to ensure that the peripheral is not tilted during insertion. If tilted insertion occurs, the device will not function properly, and in severe cases, the slot may break or the gold fingers may be scratched. Therefore, a connecting component is needed to assist in the installation of plug-in peripherals. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic data processing motherboard connection component and a motherboard to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an electronic data processing motherboard connection assembly, including a mounting bracket, mounting blocks, a synchronous motion assembly, and a locking assembly. The mounting bracket has a slot for inserting peripherals fixed at its bottom. Two symmetrical sliding grooves are provided on the mounting bracket. Two mounting blocks are respectively locked onto both sides of the peripheral. The mounting blocks are detachably slidably connected within the sliding grooves. The synchronous motion assembly includes symmetrically arranged telescopic rods and symmetrically arranged load-bearing rings. The two telescopic rods are symmetrically rotatably connected to the mounting bracket. The two load-bearing rings are respectively fixedly connected to the two adjacent ends of the two telescopic rods. The two load-bearing rings are staggered and jointly lock onto a force-applying column slidably connected to the mounting bracket by a locking element. The locking assembly is used to lock the mounting blocks when they slide within the sliding grooves and moves with the mounting blocks. In conjunction with the synchronous motion assembly, it assists in leveling the peripherals during insertion into the slots.

[0007] Furthermore, the clamping assembly includes a slider and a clamping block. The slider is vertically slidably connected to the mounting bracket, and the end of the telescopic rod away from the load-bearing ring is rotatably connected to the underside of the slider. The side of the mounting block has a protrusion. As the protrusion moves down along the slide groove, it abuts against the slider and drives the slider to slide down synchronously. The slider drives the clamping block to move along a right-angle groove through a transmission rod. During the movement of the clamping block in the right-angle groove, there is a preparatory stroke for the unclamped protrusion and a pushing stroke for the clamped protrusion.

[0008] Furthermore, the sidewall of the slide is provided with at least one first guide groove and at least one second guide groove. The protrusion slides on the first guide groove through a first guide block fixedly connected to it, and the slider slides on the second guide groove through a second guide block fixedly connected to it. Both the first guide groove and the second guide groove are vertically opened.

[0009] Furthermore, an elastic element for pushing the slider to reset is provided below the second guide block.

[0010] Furthermore, one end of the transmission rod is rotatably connected to the side of the slider, and the other end is rotatably connected to the bottom surface of the locking block. The locking block and the protrusion are respectively provided with a first wedge-shaped surface and a second wedge-shaped surface for cooperation.

[0011] Furthermore, a guide rod is fixedly connected through the block, and the guide rod is slidably connected in the right-angle groove. The right-angle groove is divided into a horizontal section and a vertical section. When the guide rod is in the horizontal section of the right-angle groove, the block slides horizontally under the limiting action of the guide rod. When the first wedge-shaped surface of the block and the second wedge-shaped surface of the protrusion are tightly fitted together, the guide rod is at the intersection of the horizontal and vertical sections of the right-angle groove.

[0012] Furthermore, the locking component includes a rod, one end of which is fixedly connected to the force-applying column, and the other end of which is slidably connected to the mounting bracket. A locking screw is threaded onto the rod, and a locking hole with internal threads is provided on the mounting bracket.

[0013] Furthermore, a cover plate is rotatably mounted on the mounting frame, and a fixed pulley is mounted on the mounting frame. A rope passes around the fixed pulley, with one end of the rope fixedly connected to the bottom end of the support rod, and the other end of the rope passing through a hole opened on the mounting frame and fixedly connected to the top of the cover plate.

[0014] Furthermore, the first elastic element includes a thrust spring.

[0015] In a second aspect, the present invention provides a motherboard, comprising: a motherboard and the electronic data processing motherboard connection component described in any one of the above claims.

[0016] In the above technical solution, the present invention provides an electronic data processing motherboard connection assembly and a motherboard. During the process of the mounting block sliding vertically downward on the slide groove, it is connected to the synchronous motion assembly through a clamping assembly. When the clamping assembly clamps the mounting block, when the force applied to one side of the peripheral device is greater than that on the other side, the mounting block on the same side is subjected to a larger force, which is then applied to the telescopic rod through the clamping assembly. The larger force on the telescopic rod is then applied to the load-bearing ring, the force-applying column, the load-bearing ring on the other side, the telescopic rod on the other side, and the clamping assembly on the other side, and finally applied to the mounting block on the other side and the other side of the peripheral device. Thus, when the force on both sides of the peripheral device is uneven, the synchronous motion assembly and the clamping assembly work together to make the overall force on the peripheral device uniform and realize the horizontal downward movement of the peripheral device, avoiding the situation of slot breakage or gold finger scratch caused by tilting into the slot.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-12 The present invention provides an electronic data processing motherboard 1 connection assembly, including a mounting bracket 2 and mounting blocks 22. The bottom of the mounting bracket 2 is fixed with a slot 11 for inserting a peripheral device 12. Two sliding grooves 21 are symmetrically opened on the mounting bracket 2 for mounting the peripheral device 12. The mounting blocks 22 are used to fix the peripheral device 12 on both sides, assisting the peripheral device 12 to slide smoothly on the mounting bracket 2. The internal shape of the mounting blocks 22 is set according to the side shape of the peripheral device 12, which is used to more stably engage with the peripheral device 12. Each mounting block 22 has a protrusion 23 on its side, which is used to slide in the sliding groove 21.

[0022] It also includes a synchronous motion component 4, which includes symmetrically arranged telescopic rods 41 and load-bearing rings 42. The two telescopic rods 41 are rotatably connected to the mounting frame 2, and the two load-bearing rings 42 are respectively fixedly connected to the two ends of the two telescopic rods 41 that are close to each other. The two load-bearing rings 42 are staggered, and the same force-applying column 43 is locked between the two load-bearing rings 42. The force-applying column 43 is slidably connected to the mounting frame 2 in the vertical direction through a locking member 5.

[0023] Two mounting blocks 22 are snapped onto both sides of the peripheral device 12. As the mounting blocks 22 slide vertically downward on the slide groove 21, they are connected to the synchronous motion component 4 through a clamping component 3. When the clamping component 3 snaps onto the mounting block 22, if the force applied to one side of the peripheral device 12 is greater than that on the other side, the mounting block 22 on the same side will be subjected to a greater force, which will act on the telescopic rod 41 through the clamping component 3. The greater force on the telescopic rod 41 will act successively on the load-bearing ring 42, the force-applying column 43, the load-bearing ring 42 on the other side, the telescopic rod 41 on the other side, and the clamping component 3 on the other side, and finally act on the mounting block 22 on the other side and the other side of the peripheral device 12. Thus, when the force on both sides of the peripheral device 12 is uneven, the synchronous motion component 4 and the clamping component 3 work together to make the force on the peripheral device 12 uniform and realize the horizontal downward movement of the peripheral device 12, avoiding the breakage of the slot 11 or scratches on the gold fingers caused by tilting into the slot 11.

[0024] It is worth mentioning that there is another installation method. When the mounting blocks 22 on both sides are locked with the corresponding locking components 3, the operator can pull the force-applying column 43 upward. When the force-applying column 43 slides upward along the installation direction, it drives the two load-bearing rings 42 locked with it to rotate around the point of rotation connection of the telescopic rod 41 on the mounting frame 2. The two load-bearing rings 42 drive the two telescopic rods 41 to rotate. The rotation of the telescopic rods 41 drives the two sets of locking components 3 to slide downward. Each set of locking components 3 drives the mounting block 22 locked with it to slide down. Since the load-bearing rings 42 and the telescopic rods 41 are symmetrically arranged, the two sets of mounting blocks 22 slide down at the same speed, so that the external device 12 slides down smoothly. After the installation is completed, the external device 12 can be locked by the locking component 5.

[0025] The protrusion 23 has a first wedge-shaped surface. The clamping assembly 3 includes a slider 31, which is slidably connected in the vertical direction within the groove 21. When the protrusion 23 slides downward within the groove 21, it abuts against and pushes the slider 31 to slide synchronously. A transmission rod 33 is rotatably connected to the side of the slider 31. A locking block 32 is rotatably connected to the end of the transmission rod 33 away from the slider 31. The locking block 32 has a second wedge-shaped surface that cooperates with the wedge-shaped surface of the protrusion 23. A guide rod 321 is fixedly connected through the locking block 32. The guide rod 321 is slidably installed in a right-angle groove 322. When the slider 31 slides downward, it first drives the locking block 32 to move in the preparatory stroke. During this stage, the locking block 32 slides horizontally towards the slider 31 until the slider 31 is pressed down by the protrusion 23 to a certain distance. At this time, the preparatory stroke of the locking block 32 ends. At this time, the guide rod 321 is at the intersection of the horizontal and vertical parts of the right-angle groove 322. The second wedge-shaped surface of the locking block 32 and the first wedge-shaped surface of the protrusion 23 are just abutted together.

[0026] As the mounting block 22 continues to slide down, it causes the protrusion 23 and the slider 31 to continue to slide down. At this time, the slider 31 slides down and transmits a force to the locking block 32 at an angle downwards towards the slider 31 through the transmission rod 33. The horizontal component of the downward force causes the locking block 32 to always press against the protrusion 23. The vertical component of the force causes the locking block 32 to move down synchronously, so that the locking block 32 enters the advancing stroke. At this time, the guide rod 321 slides in the vertical section of the right-angle groove 322.

[0027] When the peripheral device 12 experiences uneven force at both ends, the slider 31 at the end with greater force has a greater force than the other slider 31. At this time, the slider 31 with greater force exerts a greater force on the telescopic rod 41 that is rotatably connected to it. Through the synchronous component transmission, the slider 31 on the other side is pulled by the other telescopic rod 41. The vertical component of the pulling force drives the other slider 31 and eventually drives the other locking block 32 to press down the protrusion 23, thus making the force on both sides of the peripheral device 12 uniform.

[0028] The slide 21 has two first guide grooves and two second guide grooves on its side wall. A first guide block 231 is fixedly connected to each side of the protrusion 23. The mounting block 22 slides on the first guide groove through the first guide block 231 fixedly connected to the protrusion 23. A second guide block 311 is fixedly connected to each side of the slider 31. The slider 31 slides on the second guide groove through the second guide block 311 fixedly connected to it. Both the first guide groove and the second guide groove are vertically opened.

[0029] The locking component 5 includes a support rod 51, a locking screw 52, ​​and a locking hole 521. The bottom end of the support rod 51 is fixedly connected to the force-applying column 43. The support rod 51 is slidably connected to the mounting bracket 2 in the vertical direction. The locking screw 52 is threaded onto the support rod 51. The locking hole 521 is a threaded hole that works in conjunction with the locking screw 52. When the external device 12 is inserted into the slot 11, the locking screw 52 is directly aligned with the locking hole 521. At this time, turning the locking screw 52 can lock the synchronous motion component 4. Through the connection between the synchronous motion component 4, the clamping component 3, and the mounting block 22, the movement of the external device 12 in the slot 11 is locked.

[0030] The second guide block 311 is provided with an elastic element. In this embodiment, the elastic element is a thrust spring 312 (as shown in the figure). Of course, the thrust spring 312 can be replaced by other elastic elements such as disc springs that can generate elastic force.

[0031] When it is necessary to disassemble the peripheral device 12, rotate the locking screw 52. After the locking screw 52 leaves the locking hole 521, slowly press down on the support rod 51. The support rod 51 slides down and pushes the force-applying column 43 to slide down. The sliding of the force-applying column 43 acts on the two force-bearing rings 42 that are engaged with it. The force-bearing rings 42 drive the telescopic rod 41 to rotate together along the rotation mounting point of the telescopic rod 41. The end of the telescopic rod 41 away from the force-bearing ring 42 begins to tilt upward and drives the slider 31 connected to it to move upward. The slider 31 pushes the protrusion 23 to move upward.

[0032] Although the force applied by the slider 31 to the locking block 32 via the transmission rod 33 is obliquely upward and in a direction away from the slider 31, the guide rod 321 is currently in the vertical section of the right-angle groove 322. Under the limiting effect of the right-angle groove 322, the locking block 32 still engages with the protrusion 23 of the slider 31, ensuring smooth disassembly. When the guide rod 321 moves to the intersection of the vertical and horizontal sections of the right-angle groove 322, the locking block 32 no longer slides in the vertical direction and instead moves away from the protrusion 23. When sliding in the direction, the first wedge surface and the second wedge surface separate. However, in the vertical direction, the locking block 32 and the protrusion 23 are not completely misaligned. If the operator applies too much force to the support rod 51 during disassembly, the slider 31 may push the protrusion 23 and cause the peripheral device 12 to jump. However, since the second wedge surface and the first wedge surface are not completely misaligned in the vertical direction, the peripheral device 12 will not pop out, thus avoiding damage to the peripheral device 12 caused by falling after popping out.

[0033] After disassembly, the thrust spring 312 applies a vertically upward force to the second guide block 311 slider 31, so that the slider 31 is in a slightly upper position in the second guide groove. At this time, the slider 31 applies an obliquely upward force to the locking block 32 through the transmission rod 33, and pushes the locking block 32 to slide into the innermost position along the horizontal section of the right angle groove 322. Thus, the position of the locking block 32 does not obstruct the installation of the protrusion 23 in the slide groove 21, which facilitates the installation work in the next cycle.

[0034] In another embodiment, a fixed pulley 61 is installed on the mounting bracket 2, and a cover plate 6 is rotatably mounted on the mounting bracket 2. One end of a rope 62 is fixedly connected to the cover plate 6, and then the rope 62 passes around the fixed pulley 61, with the other end fixed to the bottom surface of the support rod 51. When the peripheral device 12 is not installed, the cover plate 6 is in the state of covering the slot 11. When the peripheral device 12 is installed, the support rod 51 moves upward, driving the rope 62 to pull the cover plate 6. When disassembling, after the peripheral device 12 leaves the slot 11, the support rod 51 slides down, and the rope 62 no longer applies tension to the cover plate 6. The cover plate 6 closes the slot 11 again under its own weight. When the peripheral device 12 is not inserted, the cover plate 6 seals the slot 11, which can prevent dust and other foreign objects from entering the slot 11, thereby avoiding poor contact or friction damage to the gold fingers or the electrical connection components in the slot 11 when the peripheral device 12 is inserted.
