Description

Technical Field

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

[0002] In recent years, with the widespread use and rapid development of servers, it is now common to use an upper motherboard module and a lower motherboard module in a board-to-board connection method to achieve the signal transmission requirements between double-layer motherboard modules within the server. Generally speaking, the upper motherboard module's connector is tightly inserted into the connector of the lower motherboard module, so that the upper motherboard module is firmly connected to the lower motherboard module. In addition, the upper motherboard module has a certain weight. Therefore, if the upper motherboard module is to be removed for maintenance, the user needs to lift the upper motherboard module upward with great force and detach the upper motherboard module's connector from the lower motherboard module's connector before the upper motherboard module can be removed from the lower motherboard module. The removal process is very time-consuming and labor-intensive, and there are indeed inconveniences in use. It is urgent for practitioners to further carefully consider and explore 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 highly practical.

[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 base arranged on the first motherboard unit, a frame connected to the fixing base and movable up and down relative to the fixing base, and a handle module. The fixing base 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 that is parallel to and spaced from the bottom plate of the fixing seat and is used to support the second mainboard unit, and two support modules that extend downward from two opposite sides of the top frame module and are respectively connected to the fixed frames of the fixing seat.

Each support module has a first bracket that is coupled to the corresponding fixed frame and can move horizontally relative to the corresponding fixed frame, and a plurality of linkage frame units that 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 coupled position and a detached position. In the engaged position, the top frame module is close to the bottom plate of the fixed base, 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 separate the second connection module from the first connection module. The handle module includes a pivot axis unit that passes through the fixed frame of the fixed base and the first bracket of the frame, two gear units that are sleeved and engaged with the pivot axis unit and respectively engage with the rack portion of the first bracket, and a handle unit fixed to the pivot axis unit. Rotating the handle unit causes the pivot axis unit to rotate and synchronously causes the gear unit to rotate, causing the meshed rack portion to drive the first bracket to move horizontally, and drive the linkage unit to link the top frame module to move between the engaged position and the detached position.

[0005] The cam is secured to the chassis and has a first end secured thereto, and the cam is secured to the chassis by a second means for sliding the cam into engagement with the chassis.

[0006] The cam is secured to the chassis and has a first end secured thereto, and the cam is secured to the chassis by a second end secured thereto. The cam is secured to the chassis by a second end secured thereto. The cam is secured to the chassis by a second end secured thereto.

[0007] In particular, each fixed frame has a frame body and a plurality of slide grooves that pass through 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 further has a plurality of air flow openings spaced apart and extending through the frame body.

[0009] Specifically, in the engaged position, the fixing rod of each linkage unit of each support module forms a first angle with the corresponding linkage rod; in the disengaged position, the fixing rod of each linkage unit forms a second angle with the corresponding linkage rod, wherein 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 grip portion disposed on the handle body. The grip 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 multiple first connection ports, the second connection module of the second mainboard unit has multiple second connection ports corresponding to the first connection ports, the lower opening unit of the bottom plate of the fixing seat has multiple first openings corresponding to the first connection ports, and the upper opening unit of the top frame module of the frame has multiple 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 so 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 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 rotated synchronously so that the engaged 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 base plate and push the second motherboard unit upward. When it moves to the detachment position, the top frame module moves away from the base 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 achieving time-saving and labor-saving and good practicality.

[0021] 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.

[0022] See 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 coupled to 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 detachably plugged and connected to the first connection module 911. The motherboard quick-release device is disposed 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 base 1 disposed on the first motherboard unit 91, a frame 2 connected to the fixing base 1 and movable up and down relative to the fixing base 1, and a handle module 3.

[0023] The fixing base 1 includes a bottom plate 11 coupled to the first mainboard unit 91 and two fixing frames 12 extending upward from 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 mainboard unit 91.

[0024] The frame 2 includes a top frame module 21 spaced parallel to the bottom plate 11 of the fixing base 1 and configured to support the second mainboard unit 92, and two support modules 22 extending downward from opposite sides of the top frame module 21 and respectively connected to the fixing frame 12 of the fixing base 1. The top frame module 21 has an upper opening unit 211 corresponding to the lower opening unit 111 and allowing the second connecting module 921 of the second mainboard unit 92 to pass through.

[0025] Each support module 22 has a first bracket 23 coupled to the corresponding fixed frame 12 and capable of horizontal movement relative to the corresponding fixed frame 12, and a plurality of linkage units 24 disposed on the first bracket 23 and connected to the top frame module 21. The linkage units 24 are driven by the first bracket 23 to cause 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, driving the linkage units 24 to move the top frame module 21 between an engaged position and a disengaged position. When in the combined position, the top frame module 21 is close to the bottom plate 11 of the fixing seat 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.

[0026] The handle module 3 includes a pivot unit 31 that passes through the fixed frame 12 of the fixing base 1 and the first bracket 23 of the frame 2, two gear units 32 that are sleeved and coupled to the pivot unit 31 and respectively engage with the rack portions 231 of the first bracket 23, and a handle unit 33 fixed to the pivot unit 31. Rotating the handle unit 33 rotates the pivot unit 31 and the gear unit 32, causing the engaged rack portions 231 to drive the first bracket 23 to move horizontally, thereby driving the linkage unit 24 to link the top frame module 21 between the engaged position and the detached position.

[0027] During assembly, the frame 2 is coupled to the first mainboard unit 91 as shown in the figure and is located in the coupled position. Then, in the coupled position, the second connecting module 921 of the second mainboard unit 92 is inserted through the upper opening unit 211 and into the lower opening unit 111 to be connected to the first connecting module 911 of the first mainboard unit 91, and the second mainboard unit 92 is electrically connected to the first mainboard unit 91, thus completing the assembly operation. In contrast, to detach the second mainboard unit 92, 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 rotating the pivot shaft unit 31 and driving the gear unit 32 to rotate, so that the meshed rack portion 231 drives the first bracket 23 to move horizontally in the direction A, thereby driving the linkage 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. When the top frame module 21 moves to the detached position, it 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. 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 remove the second connection module 921 from the first connection module 911 with less effort. Finally, the user only needs to move the second mainboard unit 92 upward and move the second connection module 921 upward out of the upper opening unit 211 to remove the second mainboard unit 92 for subsequent maintenance operations, and the removal operation is completed. After removal, apply force to the handle unit 33 in the counterclockwise direction ( Figure 7 The frame 2 is rotated (in the L direction) and drives the pivot shaft unit 31 to pivot, and simultaneously rotates the gear unit 32, causing the meshed rack portion 231 to drive the first bracket 23 to move horizontally in the B direction, thereby driving the linkage frame unit 24 to link the top frame module 21 to move closer to the bottom plate 11 and move it to the combined position. Simply put, in this embodiment, the default position of the frame 2 is in the combined position, so that during the assembly process, the second connection module 921 of the second mainboard unit 92 can be inserted through the upper opening unit 211 and into the lower opening unit 111 to be connected to the first connection module 911 of the first mainboard unit 91, but the present invention is not limited to this.

[0028] It is worth mentioning 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 into the first opening 112 of the lower opening unit 111 to be plugged and connected to the first connection port 912, but the present invention 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 mainboard 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 mainboard unit 91, so as to guide the second connection port 922 of the second mainboard unit 92 to be accurately inserted and connected to the first connection port 912 of the first mainboard unit 91, so that the second mainboard unit 92 forms an electrical connection with the first mainboard unit 91.

[0029] In addition, it should be noted that in this embodiment, the handle unit 33 of the handle module 3 includes a handle body 331 fixedly connected to the pivot unit 31 and capable of driving the pivot unit 31 to rotate, and a grip portion 332 disposed on the handle body 331. The grip portion 332 and the pivot unit 31 are located at 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 grip 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 fixed on the pivot shaft unit 31 to rotate and link the meshed rack portion 231, and 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.

[0030] 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 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 cause the gear unit 32 to rotate so that the engaged 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 upward. 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 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 less effort, thereby facilitating the subsequent detachment operation of detaching the second main board unit 92 from the first main board unit 91, thereby saving time and effort and having good practicality.

[0031] It should be noted that, in this embodiment, each linkage 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 pivoted on the fixing rod 25 and connected to the top frame module 21. In the engaged position, when the handle unit 33 drives the pivot unit 31 to rotate clockwise, causing the gear unit 32 to rotate, causing the meshed rack portion 231 to drive the first bracket 23 to move horizontally, thereby driving the fixed rod 25 of the linkage unit 24 to move and linking the linkage rod 26 to move upward, causing the linkage rod 26 to support the top frame module 21 and move the top frame module 21 away from the base plate 11, thereby pushing the second main board unit 92 upward. When the top frame module 21 moves to the disengaged position, the top frame module 21 moves away from the base plate 11 and pushes the second main board unit 92 upward, causing the second connecting module 921 to detach from the first connecting module 911, but the present invention is not limited to this. In particular, in this embodiment, the fixed rod 25 of each linkage unit 24 and the corresponding linkage rod 26 are a pair of reverse-linked rods, but the present invention is not limited to this. Specifically, in this embodiment, the fixing rod 25 of each linkage unit 24 of each support module 22 of the frame 2 has a fixed end 251 fixed to the corresponding first bracket 23 and a pivotal end 252 pivotally connected to the linkage rod 26. In the engaged position, when the handle unit 33 drives the pivot unit 31 to rotate clockwise, causing the gear unit 32 to rotate, the meshed rack portion 231 drives the first bracket 23 to move horizontally, thereby driving the fixed end 251 of the fixing rod 25 of the linkage unit 24 to move, and causing the pivotal end 252 of the fixing rod 25 to link the linkage rod 26 to move upward, causing the linkage rod 26 to support the top frame module 21 and move the top frame module 21 away from the bottom plate 11, thereby pushing the second main board unit 92 upward and moving it to the detached position, but the present invention is not limited thereto. In addition, in this embodiment, in the engaged position, the fixing rod 25 of each linkage unit 24 of each support module 22 and the corresponding linkage rod 26 form a first angle a (see figure); in the disengaged position, the fixing rod 25 of each linkage 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 is not limited thereto.

[0032] It should be noted that, in this embodiment, each fixed frame 12 has a frame body 121 and a plurality of slots 122 extending through the frame body 121 at intervals. The first bracket 23 and the linkage frame unit 24 of each support module 22 of the frame 2 are located on opposite sides of the frame body 121 of the corresponding fixed frame 12. Each support module 22 also has a plurality of slots 122 corresponding to each fixed frame 12 and a fixing member 27 for connecting the linkage frame unit 24 to the first bracket 23. Each fixing member 27 passes through the slot 122 of the corresponding fixed frame 12, and the two opposite ends of each fixing member 27 are fixed to the corresponding linkage frame unit 24 and the corresponding first bracket 23, respectively, but the present invention is not limited to this. That is, the fixing member 27 of each support module 22 can move left and right relative to the corresponding slide slot 122 of the fixed frame 12, and the two opposite ends of each fixing member 27 are respectively fixed to the corresponding linkage unit 24 and the corresponding first bracket 23. When the gear unit 32 rotates, it links the meshed rack portion 231 to move, thereby driving 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 links the fixing member 27 to move, causing the other end of the fixing member 27 to move the linkage unit 24, thereby linking the top frame module 21 to move between the engaged position and the disengaged position. It is worth noting that in this embodiment, each fixed frame 12 also has a plurality of airflow openings 123 spaced apart and extending through the frame body 121. In other words, the airflow openings 123 of the fixed frame 12 are cleverly designed to allow internal heat dissipation airflow to flow through the airflow openings 123, thereby meeting internal heat dissipation requirements, but the present invention is not limited to this.

[0033] In summary, the motherboard quick-release device of the present invention is designed so that the first bracket 23 of the support module 22 can be controlled to move horizontally and drive the linkage 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 pivot the pivot unit 31 and simultaneously rotate the gear unit 32 so that the meshed rack portion 231 drives the first bracket 23 to move horizontally, the linkage unit 24 can be driven to link the top frame module 21. When the second mainboard unit 92 is pushed upward while moving away from the base plate 11 and to the detachment position, the top frame module 21 moves away from the base 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 and labor-saving and good practicality.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
