Description
Technical Field
The present invention relates to a heat dissipation module and a linkage mechanism, and more particularly, to a linkage mechanism for fixing a heat dissipation member to a fixing frame and a heat dissipation module having the linkage mechanism.
Background
The development of heat dissipation modules is relevant to the development of electronic devices. Since the current in the circuit generates unnecessary heat due to the impedance when the electronic device is in operation, if the heat is not effectively removed and accumulated on the electronic components inside the electronic device, the electronic components may be damaged due to the rising temperature. At present, a heat dissipation module in the prior art utilizes screws to fix a heat dissipation member on a fixing frame. Due to the limited space in the electronic device, the operator is not easy to operate the screw. In addition, the action range of the screw is blocked by other elements in the electronic device, so that an operator cannot judge whether the screw is installed in place in real time. Moreover, it takes much time to lock and attach the screw, and the operator can only lock and attach or detach one screw at the same time, which results in low installation efficiency.

In practical applications, the heat dissipation module 1 may be disposed in a computer, a server, or other electronic devices with heat dissipation requirements. The heat sink 12 is disposed on the fixing frame 10, and the linkage mechanism 14 is used to fix the heat sink 12 on the fixing frame 10. The fixing frame 10 has two elastic pieces 100. The heat sink 12 has two first sliding slots 120, two second sliding slots 122 and a plurality of heat dissipating fins 124, wherein the two first sliding slots 120 are located at two opposite sides of the heat dissipating fins 124, and the two second sliding slots 122 are also located at two opposite sides of the heat dissipating fins 124.
As shown in fig. 4 and 5, the linking mechanism 14 includes two first sliding members 140, two second sliding members 142, two moving members 144, two linking members 146, two driving members 148a and 148b, and a handle 150. One of the driving members 148a, 148b is connected to the two first sliding members 140, and the other of the driving members 148a, 148b is connected to the two second sliding members 142. In this embodiment, two first sliding members 140 can be fixed to the two opposite sides of the driving member 148a by two fixing members 152 (e.g., screws), and two second sliding members 142 can be fixed to the two opposite sides of the driving member 148b by two fixing members 152. Each linkage 146 connects one of the first sliding members 140 and one of the second sliding members 142. In this embodiment, the first sliding member 140 and the second sliding member 142 can be fixed to two opposite sides of the linking member 146 by two fixing members 152.
Each of the first sliding members 140 has a first inclined surface 1400, each of the second sliding members 142 has a second inclined surface 1420, and each of the moving members 144 has a third inclined surface 1440 and a fourth inclined surface 1442. The moving member 144 is movably disposed between the first sliding member 140 and the second sliding member 142, such that the first inclined surface 1400 of the first sliding member 140 abuts against the third inclined surface 1440 of the moving member 144, and the second inclined surface 1420 of the second sliding member 142 abuts against the fourth inclined surface 1442 of the moving member 144. In addition, each of the first sliders 140 has a first slide rail 1402, and each of the second sliders 142 has a second slide rail 1422. The first slide rail 1402 of the first slider 140 is slidably disposed in the first slide slot 120 of the heat sink 12, such that the first slider 140 can slide relative to the heat sink 12. The second slide rail 1422 of the second sliding member 142 is slidably disposed in the second slide slot 122 of the heat sink 12, so that the second sliding member 142 can slide relative to the heat sink 12.
In this embodiment, each of the linking members 146 may have a fifth inclined surface 1460 and a sixth inclined surface 1462, and each of the moving members 144 may have a seventh inclined surface 1444 and an eighth inclined surface 1446. After the linkage mechanism 14 is assembled, the fifth inclined surface 1460 of the linkage member 146 abuts against the seventh inclined surface 1444 of the moving member 144, and the sixth inclined surface 1462 of the linkage member 146 abuts against the eighth inclined surface 1446 of the moving member 144.
As shown in fig. 4 to 7, the handle 150 has two rotating portions 1500 and two connecting rods 1502, and each moving member 144 has a long slot 1448. One end of the link 1502 is disposed in the rotating portion 1500. In this embodiment, each rotating portion 1500 of the handle 150 has a cam structure 1504. Therefore, when the handle 150 is rotated, the cam structure 1504 drives the link 1502 to move up and down. In addition, the other end of the link 1502 is disposed in the long slot 1448, such that the link 1502 can move in the long slot 1448. In this embodiment, the link 1502 may have a limiting portion 1506, wherein the link 1502 is limited in the slot 1448 by the limiting portion 1506.
Referring to fig. 8 to 14, fig. 8 is a sectional view of the heat dissipation module 1 of fig. 1 along line B-B, fig. 9 is a sectional view of the heat dissipation module 1 of fig. 1 along line C-C, fig. 10 is a perspective view of the driving member 148a of fig. 1 after being pushed, fig. 11 is a sectional view of the heat dissipation module 1 of fig. 10 along line D-D, fig. 12 is a sectional view of the heat dissipation module 1 of fig. 10 along line E-E, fig. 13 is a perspective view of the handle 150 of fig. 10 after being rotated, and fig. 14 is a sectional view of the heat dissipation module 1 of fig. 13 along line F-F.
In this embodiment, the two driving members 148a and 148b can drive the two moving members 144 to move towards the two resilient sheets 100 of the fixing frame 10 or to move away from the two resilient sheets 100 of the fixing frame 10 by the cooperation of the two first sliding members 140, the two second sliding members 142 and the two linking members 146, so that the engaging end 1450 of the moving member 144 moves to below the resilient sheets 100 or moves out from below the resilient sheets 100. In addition, when the engaging end 1450 of the moving member 144 moves to a position below the resilient sheet 100 of the fixing frame 10, the handle 150 can be rotated, so that the link 1502 of the handle 150 pulls the moving member 144, and the engaging end 1450 of the moving member 144 lifts up the resilient sheet 100. The detailed operation principle of the interlocking mechanism 14 of the present invention will be described below with reference to fig. 1 and 8 to 14.
When an operator wants to fix the heat dissipating member 12 to the fixing frame 10 by using the interlocking mechanism 14, the operator first sets the heat dissipating member 12 and the interlocking mechanism 14 on the fixing frame 10. At this time, as shown in fig. 1, 8 and 9, the handle 150 is supported on the driving element 148b, the second sliding element 142 is closely attached to the moving element 144, and the engaging end 1450 of the moving element 144 is far away from the resilient sheet 100 of the fixing frame 10.
Then, the operator can push the driving element 148a in the direction of the arrow a1, so that the driving element 148a drives the first sliding element 140, the linking element 146, and the second sliding element 142 to move in the direction of the arrow a 1. At this time, the first inclined surface 1400 of the first sliding member 140 pushes the third inclined surface 1440 of the moving member 144, and the fifth inclined surface 1460 of the linking member 146 pushes the seventh inclined surface 1444 of the moving member 144, so that the moving member 144 moves toward the resilient sheet 100 of the fixing frame 10, as shown in fig. 10 to 12. At this time, the engaging end 1450 of the moving member 144 moves to a position below the resilient sheet 100 of the fixing frame 10, and the first sliding member 140 is close to and attached to the moving member 144. Then, the operator can rotate the handle 150 in the direction of the arrow R1, so that the cam structure 1504 drives the link 1502 to move upward, and further drives the moving member 144 to move upward. At this time, the engaging end 1450 of the moving member 144 lifts the resilient sheet 100 of the fixing frame 10, and the handle 150 abuts against the driving member 148a, as shown in fig. 13 to 14. Thus, the heat sink 12 can be fixed on the fixing frame 10 by the interlocking mechanism 14.
When an operator desires to detach the heat sink 12 from the fixing bracket 10, the operator may rotate the handle 150 in the direction of the arrow R2. At this time, the elastic force generated by the elastic sheet 100 of the fixing frame 10 drives the engaging end 1450 of the moving member 144 to move downward, so as to return to the state shown in fig. 10. Then, the operator can push the driving element 148b in the direction of the arrow a2, so that the driving element 148b drives the second sliding element 142, the linking element 146 and the first sliding element 140 to move in the direction of the arrow a 2. At this time, the second inclined surface 1420 of the second sliding member 142 pushes the fourth inclined surface 1442 of the moving member 144, and the sixth inclined surface 1462 of the linking member 146 pushes the eighth inclined surface 1446 of the moving member 144, so that the moving member 144 is away from the resilient piece 100 of the fixing frame 10, as shown in fig. 1, 8 and 9. At this time, the operator can detach the heat sink 12 and the interlocking mechanism 14 from the fixing frame 10.
In summary, the heat sink is fixed to the fixing frame by the linkage mechanism. When an operator wants to fix the heat sink on the fixing frame, the operator can push one of the two driving members, so that the driving member drives the two moving members to move towards the two elastic sheets of the fixing frame by the cooperation of the two first sliding members, the two second sliding members and the two linking members. At this time, the engaging end of the moving member can move to the lower part of the elastic sheet of the fixing frame. Then, the operator can rotate the handle to lift the elastic sheet of the fixed mount by the clamping end of the moving member, so that the heat dissipation member is fixed on the fixed mount. When an operator wants to detach the heat sink from the fixing frame, the operator can rotate the handle to reset the elastic sheet of the fixing frame. Then, the operator can push the other of the two driving members, so that the driving member drives the two moving members to move away from the two elastic sheets of the fixing frame by the cooperation of the two first sliding members, the two second sliding members and the two linking members. At this time, the operator can detach the heat sink from the fixing frame.
Because the operator only needs to push the driving piece and the rotating handle, the operator can easily operate the linkage mechanism in a limited space and save the installation time. In addition, an operator can visually check whether the interlocking mechanism of the present invention is mounted in place, to ensure that the heat sink can be stably fixed to the fixing frame.
