Description

Technical Field

[0001] The invention relates to a motherboard device, in particular to a motherboard quick-release device. Background Art

[0002] In recent years, with the widespread application and rapid development of servers, it is now common to use the upper motherboard module and the lower motherboard module in the server to achieve the signal transmission between the double-layer motherboard modules through the board to board combination method. Generally speaking, the upper motherboard module is firmly combined with the lower motherboard module by tightly inserting the connector of the upper motherboard module into the connector of the lower motherboard module, and the upper motherboard module has a certain weight. Therefore, if the upper motherboard module is to be disassembled for maintenance, the user needs to lift the upper motherboard module upward very hard and disassemble the connector of the upper motherboard module from the connector of the lower motherboard module before the upper motherboard module can be moved away from the lower motherboard module. The disassembly process is very time-consuming and labor-intensive, and there are indeed inconveniences in use, which requires practitioners to further carefully think about and discuss improvements. Summary of the invention

[0003] Therefore, the purpose of the present invention is to provide a motherboard quick-release device that is labor-saving and has good practicality.

[0004] Therefore, the motherboard quick-release device of the present invention is suitable for installation in a double-layer motherboard device, which includes a first motherboard unit, and a second motherboard unit detachably coupled to the first motherboard unit and located above the first motherboard unit. The first motherboard unit has a first connection module. The second motherboard unit has a second connection module detachably plugged and connected to the first connection module. The motherboard quick-release device is arranged on the first motherboard unit and is used to assist in detaching the second motherboard unit from the first motherboard unit. The motherboard quick-release device includes a fixing seat arranged on the first motherboard unit, a frame connected to the fixing seat and movable up and down relative to the fixing seat, and a handle module. The fixing seat includes a bottom plate coupled to the first motherboard unit, and two fixed frames extending upward from two opposite sides of the bottom plate. The bottom plate has a lower opening unit corresponding to the first connection module of the first motherboard unit. The frame includes a top frame module which is parallel and spaced from the bottom plate of the fixing seat and is used to support the second mainboard unit, and two support modules which extend downward from two opposite sides of the top frame module and are respectively connected to the fixed frames of the fixing seat. The top frame module has an upper opening unit corresponding to the lower opening unit and through which the second connecting module of the second mainboard unit can pass. Each support module has a first bracket which is combined with the corresponding fixed frame and can move horizontally relative to the corresponding fixed frame, and a plurality of linkage frame units which are arranged on the first bracket and connected to the top frame module, and can be driven by the first bracket to link the top frame module to move up and down. Each first bracket has a rack portion. The first bracket of the support module can be controlled to move horizontally and drive the linkage frame unit to link the top frame module to move between a combined position and a detached position. In the combined position, the top frame module is close to the bottom plate of the fixed seat, and the second connection module of the second mainboard unit passes through the upper opening unit of the top frame module and the lower opening unit of the bottom plate and can be inserted into the first connection module connected to the first mainboard unit; in the detached position, the top frame module is away from the bottom plate and can push the second mainboard unit upward to make the second connection module detach from the first connection module. The handle module includes a pivot unit that passes through the fixed frame of the fixed seat and the first bracket of the frame, two gear units that are combined with the pivot unit and respectively meshed with the rack portion of the first bracket, and a handle unit fixed on the pivot unit. The rotation of the handle unit will cause the pivot unit to rotate and synchronously cause the gear unit to rotate so that the meshed rack portion drives the first bracket to move horizontally, and drives the linkage unit to link the top frame module to move between the combined position and the detached position.

[0005] In particular, each linkage frame unit of each supporting module of the frame has a fixing rod fixedly mounted on the corresponding first bracket, and a linkage rod pivotally mounted on the fixing rod and connected to the top frame module. When in the combined position, when the handle unit drives the pivot shaft unit to rotate in a clockwise direction and causes the gear unit to rotate, the meshed rack portion drives the first bracket to move horizontally, and drives the fixing rod of the linkage frame unit to move and links the linkage rod to move upward, so that the linkage rod supports the top frame module and moves the top frame module away from the bottom plate and pushes the second main board unit upward, and when it moves to the detached position, the top frame module moves away from the bottom plate and pushes the second main board unit upward, so that the second connection module is separated from the first connection module.

[0006] In particular, the fixing rod of each linkage frame unit of each supporting module of the frame has a fixing end fixed on the corresponding first bracket and a pivot end pivotally connected to the linkage rod. When in the combined position, when the handle unit drives the pivot shaft unit to rotate in the clockwise direction and the gear unit rotates, the meshed rack portion drives the first bracket to move horizontally, and drives the fixed end of the fixing rod of the linkage frame unit to move and causes the pivot end of the fixing rod to link the linkage rod to move upward, so that the linkage rod supports the top frame module and moves the top frame module away from the bottom plate to push the second main board unit upward, and moves to the detached position.

[0007] In particular, each fixed frame has a frame body and a plurality of slide grooves that penetrate the frame body at intervals. The first bracket of each support module of the frame and the linkage frame unit are respectively located on two opposite sides of the frame body of the corresponding fixed frame. Each support module also has a plurality of slide grooves corresponding to each fixed frame and is used to combine the linkage frame unit with a fixing member on the first bracket. Each fixing member passes through the slide groove of the corresponding fixed frame and the two opposite ends of each fixing member are respectively fixed to the corresponding linkage frame unit and the corresponding first bracket.

[0008] In particular, each fixed frame also has a plurality of air flow openings spaced apart and extending through the frame body.

[0009] In particular, in the combined position, the fixing rod of each linkage frame unit of each support module and the corresponding linkage rod form a first angle with each other; in the detached position, the fixing rod of each linkage frame unit and the corresponding linkage rod form a second angle with each other, the first angle is greater than 90 degrees and less than 180 degrees, and the second angle is less than 90 degrees.

[0010] Particularly, the handle unit of the handle module has a handle body fixedly connected to the pivot unit and capable of driving the pivot unit to rotate, and a gripping portion disposed on the handle body, wherein the gripping portion and the pivot unit are located at two opposite ends of the handle body.

[0011] In particular, the first connection module of the first mainboard unit has a plurality of first connection ports, the second connection module of the second mainboard unit has a plurality of second connection ports corresponding to the first connection ports, the lower opening unit of the bottom plate of the fixing seat has a plurality of first openings corresponding to the first connection ports, and the upper opening unit of the top frame module of the frame has a plurality of second openings corresponding to the first openings of the lower opening unit. When in the combined position, the second connection port of the second mainboard unit passes through the second opening of the upper opening unit and penetrates into the first opening of the lower opening unit to be inserted and connected to the first connection port.

[0012] Compared with the prior art, the motherboard quick-release device of the present invention is designed that the first bracket of the supporting module can be controlled to move horizontally and drive the linkage frame unit to link the top frame module to move to the detachment position. When in the combined position, as long as the handle unit is forced to drive the pivot shaft unit to pivot and the gear unit is synchronously rotated so that the meshed rack portion drives the first bracket to move horizontally, the linkage frame unit can be driven to link the top frame module to move away from the bottom plate and push the second motherboard unit upward. When moving to the detachment position, the top frame module moves away from the bottom plate and pushes the second motherboard unit upward to separate the second connection module from the first connection module, effectively assisting the user to directly detach the second connection module from the first connection module with less effort, and facilitating the subsequent detachment operation of detaching the second motherboard unit from the first motherboard unit, thereby saving time and effort and having good practicality.

Implementation

[0014] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0015] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The motherboard quick-release device of the present invention is suitable for installation in a double-layer motherboard device 90, which includes a first motherboard unit 91 and a second motherboard unit 92 detachably combined with the first motherboard unit 91 and located above the first motherboard unit 91. The first motherboard unit 91 has a first connection module 911. The second motherboard unit 92 has a second connection module 921 that is detachably plugged and connected to the first connection module 911. The motherboard quick-release device is arranged on the first motherboard unit 91 and is used to assist in detaching the second motherboard unit 92 from the first motherboard unit 91. The motherboard quick-release device includes a fixing seat 1 arranged on the first motherboard unit 91, a frame 2 connected to the fixing seat 1 and movable up and down relative to the fixing seat 1, and a handle module 3.

[0016] The fixing base 1 includes a bottom plate 11 combined with the first main board unit 91 and two fixing frames 12 extending upward from two opposite sides of the bottom plate 11. The bottom plate 11 has a lower opening unit 111 corresponding to the first connecting module 911 of the first main board unit 91.

[0017] The frame 2 includes a top frame module 21 which is parallel and spaced from the bottom plate 11 of the fixing base 1 and is used to support the second main board unit 92, and two support modules 22 which extend downward from two opposite sides of the top frame module 21 and are respectively connected to the fixing frame 12 of the fixing base 1. The top frame module 21 has an upper opening unit 211 which corresponds to the lower opening unit 111 and allows the second connection module 921 of the second main board unit 92 to pass through.

[0018] Each support module 22 has a first bracket 23 that is combined with the corresponding fixed frame 12 and can move horizontally relative to the corresponding fixed frame 12, and a plurality of linkage frame units 24 that are arranged on the first bracket 23 and connected to the top frame module 21, and can be driven by the first bracket 23 to link the top frame module 21 to move up and down. Each first bracket 23 has a rack portion 231. The first bracket 23 of the support module 22 can be controlled to move horizontally and drive the linkage frame unit 24 to link the top frame module 21 to move between a combined position and a detached position. When in the combined position, the top frame module 21 is close to the bottom plate 11 of the fixing base 1, and the second connection module 921 of the second main board unit 92 passes through the upper opening unit 211 of the top frame module 21 and the lower opening unit 111 of the bottom plate 11 and can be inserted into the first connection module 911 connected to the first main board unit 91; when in the detached position, the top frame module 21 is away from the bottom plate 11 and can push the second main board unit 92 upward to separate the second connection module 921 from the first connection module 911.

[0019] The handle module 3 includes a pivot unit 31 that penetrates the fixed frame 12 of the fixing seat 1 and the first bracket 23 of the frame 2, two gear units 32 that are mounted on the pivot unit 31 and meshed with the racks 231 of the first bracket 23, and a handle unit 33 that is fixed on the pivot unit 31. The rotation of the handle unit 33 causes the pivot unit 31 to rotate and the gear unit 32 to rotate synchronously, so that the meshed rack 231 drives the first bracket 23 to move horizontally, and drives the linkage unit 24 to link the top frame module 21 to move between the combined position and the detached position.

[0020] During assembly, the frame 2 is combined with the first mainboard unit 91 as shown in the figure and is located at the combined position. Then, at the combined position, the second connection module 921 of the second mainboard unit 92 passes through the upper opening unit 211 and penetrates the lower opening unit 111 to be inserted into the first connection module 911 connected to the first mainboard unit 91, and the second mainboard unit 92 is electrically connected to the first mainboard unit 91, and the assembly action is completed. Relatively speaking, if the second mainboard unit 92 is to be detached, the user only needs to apply force to the handle unit 33 in the clockwise direction ( Figure 6The first bracket 23 is moved horizontally in the direction A by the gear unit 32 so that the meshed rack portion 231 drives the first bracket 23 to move horizontally in the direction A, thereby driving the linkage frame unit 24 to link the top frame module 21 to move away from the bottom plate 11 and generate an upward force to push the second main board unit 92 upward, and when it moves to the detached position, the top frame module 21 is away from the bottom plate 11 and pushes the second main board unit 92 upward to make the second connection module 921 detach from the first connection module 911. At this time, since the second connection module 921 has been initially separated and is not connected to the first connection module 911, the user does not need to lift the second mainboard unit 92 upward to pull the second connection module 921 away from the first connection module 911, and the user can directly detach the second connection module 921 from the first connection module 911 with less effort. Finally, the detachment operation is completed by moving the second mainboard unit 92 upward and moving the second connection module 921 upward out of the upper opening unit 211 to detach the second mainboard unit 92 for subsequent maintenance operations. After detachment, apply force to rotate the handle unit 33 in the counterclockwise direction ( Figure 7 The first bracket 23 is driven by the meshed rack portion 231 to move horizontally in the B direction, and the linkage frame unit 24 is driven to link the top frame module 21 to move in the direction close to the bottom plate 11 and move to the combined position. In short, in this embodiment, the default position of the frame 2 is located at the combined position, so that the second connection module 921 of the second main board unit 92 passes through the upper opening unit 211 and penetrates the lower opening unit 111 during the assembly process, and can be plugged into the first connection module 911 connected to the first main board unit 91, but it is not limited thereto.

[0021] It is particularly mentioned that in this embodiment, the first connection module 911 of the first mainboard unit 91 has a plurality of first connection ports 912, and the second connection module 921 of the second mainboard unit 92 has a plurality of second connection ports 922 corresponding to the first connection ports 912. The lower opening unit 111 of the bottom plate 11 of the fixing base 1 has a plurality of first openings 112 corresponding to the first connection ports 912. The upper opening unit 211 of the top frame module 21 of the frame 2 has a plurality of second openings 212 corresponding to the first openings 112 of the lower opening unit 111. In the combined position, the second connection port 922 of the second connection module 921 of the second mainboard unit 92 passes through the second opening 212 of the upper opening unit 211 and penetrates into the first opening 112 of the lower opening unit 111 to be inserted and connected to the first connection port 912, but is not limited thereto. To be more specific, the second opening 212 of the upper opening unit 211 of the top frame module 21 is designed to correspond to the first opening 112 of the lower opening unit 111 of the bottom plate 11 as shown in the figure, so that the second connection port 922 of the second connection module 921 of the second main board unit 92 passes through the second opening 212 of the upper opening unit 211 and the first opening 112 of the lower opening unit 111, and then automatically aligns with the first connection port 912 of the first connection module 911 of the first main board unit 91, so as to guide the second connection port 922 of the second main board unit 92 to be accurately inserted and connected to the first connection port 912 of the first main board unit 91 so that the second main board unit 92 forms an electrical connection with the first main board unit 91.

[0022] In addition, it should be noted that in this embodiment, the handle unit 33 of the handle module 3 has a handle body 331 fixedly connected to the pivot unit 31 and capable of driving the pivot unit 31 to rotate, and a gripping portion 332 disposed on the handle body 331. The gripping portion 332 and the pivot unit 31 are located at two opposite ends of the handle body 331. In simple terms, the gripping portion 332 and the handle body 331 are designed as shown in the figure, so that the user can directly hold the gripping portion 332 to apply force and cooperate with the handle body 331 as a force arm with a long force arm to achieve effective and labor-saving application. Therefore, the user can laboriously rotate the handle body 331 to pivot the pivot shaft unit 31 and simultaneously drive the gear unit 32 mounted on the pivot shaft unit 31 to rotate and link the meshed rack portion 231. The movement of the rack portion 231 will drive the first bracket 23 to move horizontally, and drive the linkage frame unit 24 to link the top frame module 21 to move between the combined position and the detached position, but not limited to this.

[0023] By virtue of the design that the first bracket 23 of the supporting module 22 can be controlled to move horizontally and drive the linkage frame unit 24 to link the top frame module 21 to the detached position, when in the combined position, as long as the handle unit 33 is applied with force to drive the pivot shaft unit 31 to pivot and synchronously rotate the gear unit 32 so that the meshed rack portion 231 drives the first bracket 23 to move horizontally, the linkage frame unit 24 can be driven to link the top frame module 21 to move away from the bottom plate 11 and push the second main board unit 92 upwards. When moving to the detached position, the top frame module 21 moves away from the bottom plate 11 and pushes the second main board unit 92 upwards to separate the second connecting module 921 from the first connecting module 911, effectively assisting the user to directly detach the second connecting module 921 from the first connecting module 911 with little effort, and facilitating the subsequent detachment operation of detaching the second main board unit 92 from the first main board unit 91, thereby achieving time-saving and labor-saving and good practicality.

[0024] It should be particularly noted that in this embodiment, each linkage frame unit 24 of each support module 22 of the frame 2 has a fixing rod 25 fixed on the corresponding first bracket 23, and a linkage rod 26 pivotally mounted on the fixing rod 25 and connected to the top frame module 21. In the combined position, when the handle unit 33 drives the pivot unit 31 to rotate in the clockwise direction and the gear unit 32 rotates, the meshed rack portion 231 drives the first bracket 23 to move horizontally, and drives the fixed rod 25 of the linkage frame unit 24 to move and link the linkage rod 26 to move upward, so that the linkage rod 26 supports the top frame module 21 and moves the top frame module 21 away from the bottom plate 11 to push the second main board unit 92 upward, and when it moves to the detached position, the top frame module 21 moves away from the bottom plate 11 and pushes the second main board unit 92 upward to separate the second connection module 921 from the first connection module 911, but the present invention is not limited thereto. In particular, in the present embodiment, the fixed rod 25 of each linkage frame unit 24 and the corresponding linkage rod 26 are in the form of a set of reverse linkages, but the present invention is not limited thereto. Further, in this embodiment, the fixing rod 25 of each linkage frame unit 24 of each supporting module 22 of the frame 2 has a fixing end 251 fixed on the corresponding first bracket 23, and a pivoting end 252 pivotally connected to the linkage rod 26. In the combined position, when the handle unit 33 drives the pivot unit 31 to rotate in the clockwise direction and the gear unit 32 rotates, the meshed rack portion 231 drives the first bracket 23 to move horizontally, and drives the fixing end 251 of the fixing rod 25 of the linkage frame unit 24 to move and the pivoting end 252 of the fixing rod 25 to link the linkage rod 26 to move upward, so that the linkage rod 26 supports the top frame module 21 and moves the top frame module 21 away from the bottom plate 11 to push the second main board unit 92 upward, and moves to the detached position, but the present invention is not limited thereto. In addition, in this embodiment, when in the combined position, the fixing rod 25 of each linkage frame unit 24 of each support module 22 and the corresponding linkage rod 26 form a first angle a (see figure); when in the detached position, the fixing rod 25 of each linkage frame unit 24 and the corresponding linkage rod 26 form a second angle b (see figure), the first angle a is greater than 90 degrees and less than 180 degrees, and the second angle b is less than 90 degrees, but not limited to this.

[0025] Here, it should be noted that, in the present embodiment, each fixed frame 12 has a frame body 121, and a plurality of slots 122 that are spaced apart and penetrate the frame body 121. The first bracket 23 of each support module 22 of the frame 2 and the linkage frame unit 24 are respectively located at two opposite sides of the frame body 121 of the corresponding fixed frame 12, and each support module 22 also has a plurality of slots 122 corresponding to each fixed frame 12 and a fixing member 27 for combining the linkage frame unit 24 with the first bracket 23, each fixing member 27 penetrates the slot 122 of the corresponding fixed frame 12, and the two opposite ends of each fixing member 27 are respectively fixed to the corresponding linkage frame unit 24 and the corresponding first bracket 23, but the present invention is not limited thereto. That is, through the fixing member 27 of each supporting module 22, the fixing member 27 can move left and right relative to the slide slot 122 of the corresponding fixed frame 12, and the two opposite ends of each fixing member 27 are respectively fixed to the corresponding linkage frame unit 24 and the corresponding first bracket 23. When the gear unit 32 rotates, the meshed rack portion 231 is linked to move and drive the first bracket 23 to move horizontally. Since one end of the fixing member 27 is fixed to the first bracket 23, the horizontal movement of the first bracket 23 will link the fixing member 27 to move, so that the other end of the fixing member 27 drives the linkage frame unit 24 to move, and the top frame module 21 can be linked to move between the combined position and the detached position. In particular, in this embodiment, each fixed frame 12 also has a plurality of airflow openings 123 that are spaced apart and penetrate the frame body 121. That is, the ingenuity of the airflow openings 123 of the fixed frame 12 is used to allow internal heat dissipation airflow to flow through the airflow openings 123, and internal heat dissipation requirements can be met, but not limited thereto.

[0026] In summary, the motherboard quick-release device of the present invention is designed such that the first bracket 23 of the supporting module 22 can be controlled to move horizontally and drive the linkage frame unit 24 to link the top frame module 21 to the detached position. When in the combined position, as long as the handle unit 33 is forced to drive the pivot shaft unit 31 to pivot and the gear unit 32 to rotate synchronously so that the meshed rack portion 231 drives the first bracket 23 to move horizontally, the linkage frame unit 24 can be driven to link the top frame module 21. When moving in a direction away from the bottom plate 11 and pushing the second mainboard unit 92 upward and moving to the detachment position, the top frame module 21 moves away from the bottom plate 11 and pushes the second mainboard unit 92 upward to separate the second connection module 921 from the first connection module 911, effectively assisting the user to directly detach the second connection module 921 from the first connection module 911 with less effort, and facilitating the subsequent detachment operation of detaching the second mainboard unit 92 from the first mainboard unit 91, thereby achieving time-saving, labor-saving and good practicality.

[0027] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
