Description

Server module lock plug-in assist structure

The present invention relates to the technical field of server installation structures, and in particular to a server module locking and plugging assistance structure that provides a locking function and plugging assistance when an electronic module is inserted into a server.

With the development of computer technology, in addition to its technological applications, it has also gradually expanded to the areas of daily life, such as the Internet and communication technology. Therefore, various servers have come into being. Multiple electronic modules are installed in the server to run different functions in order to provide users with various services.

However, in existing servers, multiple electronic modules are fixed in the server with bolts, which makes the installation process complicated. Therefore, the electronic modules of the server are currently plug-in and unplug-out structures without tools. However, if the electronic module is plugged in and out of the connector with a large plug-in and unplugging force in the server, the existing structure will have the problem of difficulty in plugging and unplugging under limited force.

In view of this, the purpose of the present invention is to provide a server module locking and plugging assistance structure, which provides a locking force for the electronic module when the electronic module is inserted into the server, and provides a pulling-out assistance for the electronic module when the electronic module is to be removed from the server, so as to solve the problem of the existing technology that connectors with large plugging and pulling forces are difficult to plug and pull.

An embodiment of the server module lock plug-in assist structure of the present invention includes a power-assist lock, a latch and a positioning member. The power-assist lock is pivotally connected to an electronic module, and the electronic module is inserted into a slot of the server through an opening of the server. The power-assist lock rotates between a locking position and an unlocking position. The power-assist lock includes a handle and a force-applying lock, and the handle and the force-applying lock are respectively located on both sides of the pivot between the power-assist lock and the electronic module. The latch is pivotally connected to the electronic module. When the power-assist lock is located at the locking position, the latch positions the power-assist lock at the locking position and the positioning member stops the power-assist lock. The locking member is arranged on an inner wall surface of the server and has a plane wall in the direction facing the slot. When force is applied to the handle to rotate the power-assisted locking member from the locked position to the unlocked position, the force-applying locking portion of the power-assisted locking member abuts against the plane wall of the locking member, causing the electronic module to move toward the opening in the slot.

In another embodiment, the latching member and the locking member are located on opposite sides of the hinge between the power-assisted latching member and the electronic module.

In another embodiment, the auxiliary locking member and the buckle member are provided with two mutually abutting hook structures to position the auxiliary locking member in the locking position.

When the auxiliary locking fastener is located at the locking position, the limiting groove is engaged with the limiting member.

In another embodiment, the limiting groove and the allowing groove are located on opposite sides of the hinge between the power-assisted locking fastener and the electronic module.

In another embodiment, the handle portion includes a protrusion structure, which protrudes from one side of the auxiliary locking member and is located between the locking member and the limiting member.

The server module lock plug-in and pull-out assist structure of the present invention rotates the rotatable assist lock to the locked position, and the latch makes the assist lock to be positioned at the locked position and the clamp stops the assist lock, so as to generate a lock for the electronic module. When the handle is applied to rotate the assist lock from the locked position to the unlocked position, the force-applying lock portion of the assist lock abuts against the clamp, so that the clamp applies a reaction force to the assist lock, and provides a force to remove the electronic module from the slot, so as to help the user remove the electronic module from the server. The plug-in and pull-out operation can also be easily performed for connectors with a large plug-in and pull-out force.

Please refer to the first, second, third and fourth figures, which show an embodiment of the server module lock plug-in assist structure of the present invention. The server module lock plug-in assist structure 1 of this embodiment includes an assist lock member 10, a latch member 20 and a latch member 30. The assist lock member 10 and the latch member 20 are both connected to an electronic module E, and the electronic module E is inserted into a slot SL of the server S through an opening O of the server S.

The power-assisted locking fastener 10 rotates between a locking position and an unlocking position. The power-assisted locking fastener 10 of this embodiment includes a handle portion 11, a force-applying locking portion 12, a hinge portion 13, and a first buckle portion 14. The handle portion 11 includes a protrusion structure, which protrudes from one side of the power-assisted locking fastener 10 and is located between the hinge portion 13 and the first buckle portion 14, so as to facilitate the user to apply force. The hinge portion 13 is rotatably arranged on the side wall W of the electronic module E with a rotating shaft, and the side wall W of the electronic module E corresponds to the inner side wall of the slot SL of the server S. The handle portion 11 and the force-applying buckle portion 12 are respectively located on both sides of the pivoting portion 13 where the power-assisting buckle 10 and the electronic module E are pivotally connected. The first buckle portion 14 is disposed adjacent to the handle portion 11, and the first buckle portion 14 is used to form a buckle structure with the buckle 20 to position the power-assisting buckle 10 in the locked position. The first buckle portion 14 of the present embodiment has a hook portion 141. The force-applying buckle portion 12 includes a groove 121, and the groove 121 includes a first groove wall 1211 and a second groove wall 1212 disposed opposite to each other, wherein the first groove wall 1211 is closer to the pivoting portion 13 where the power-assisting buckle 10 and the electronic module E are pivotally connected than the second groove wall 1212.

The buckle 20 is also pivoted on the side wall W of the electronic module E. The buckle 20 includes a pivot portion 21, a stop portion 22 and a second buckle portion 23. The pivot portion 21 is pivoted to the electronic module E via a rotating shaft, and two ends of a compression spring P are respectively connected to the electronic module E and the buckle 20, so that the compression spring P applies elastic force to the buckle 20.

The server module locking and plugging assisting structure 1 of the present embodiment further includes a limit pin 40, which is disposed on the electronic module E. As mentioned above, the compression spring P applies elastic force to the buckle 20, so that the buckle 20 moves toward the limit pin 40 and the limit pin 40 blocks the buckle 20. When the user applies force to rotate the buckle 20, after the user releases the buckle 20, the buckle 20 is reset due to the elastic force of the compression spring P and abuts against the limit pin 40.

The second buckle portion 23 has a hook portion 231, and the hook portion 141 of the first buckle portion 14 and the hook portion 231 of the second buckle portion 23 extend in opposite directions. Therefore, when the power-assisted fastener is located at the locked position, the hook portion 141 of the first buckle portion 14 and the hook portion 231 of the second buckle portion 23 abut against each other, so that the power-assisted fastener 10 is positioned at the locked position.

In addition, a recessed portion 142 is formed on a side of the hook portion 141 of the first buckle portion 14 away from the hook portion 231 of the second buckle portion 23. When the auxiliary locking member 10 is located at the locked position, the recessed portion 142 behind the hook portion 141 of the first buckle portion 14 of the auxiliary locking member 10 abuts against the limiting pin 40, forming a structure in which the hook portion 231 of the second buckle portion 23 and the limiting pin 40 clamp and position the hook portion 141 of the first buckle portion 14.

As shown in FIG. 5 , the locking member 30 is disposed on an inner wall surface of the server S, and the locking member 20 and the locking member 30 are located on opposite sides of the pivot portion 13 of the power-assisted locking member 10. The locking member 30 of this embodiment is a convex column, and the outer peripheral wall of the locking member 30 includes a plane wall 31 in the direction facing the slot SL and an arc wall 32 connected to the plane wall 31.

Please refer to the third figure, which further includes a stopper 50, which is disposed on the inner wall surface of the server S. Correspondingly, the power-assisted locking fastener 10 has a stopper groove 15. When the power-assisted locking fastener 10 rotates to the locked position, the stopper groove 15 engages with the stopper 50. The stopper 50 of this embodiment is a convex column, and the stopper groove 15 is a groove formed on one side of the power-assisted locking fastener 10.

As shown in the fourth figure, the user applies force to insert the electronic module E into the slot SL of the server until the first groove wall 1211 of the force-applying lock portion 12 abuts against the flat wall 31 of the locking member 30 as shown in the sixth figure, and then the user applies force to the handle portion 11 of the power-assisting lock member 10 to rotate the power-assisting lock member 10 from the unlocking position to the locking position. In the locking position, the hook portion 141 of the first locking portion 14 of the power-assisting lock member 10 abuts against the hook portion 231 of the second locking portion 23 of the locking member 20, the limiting groove 15 of the power-assisting lock member 10 is engaged with the limiting member 50, and the second groove wall 1212 of the allowing groove 121 of the force-applying lock portion 12 abuts against the arc wall 32 of the locking member 30. In this way, the power-assisting lock member 10 plays a role of locking the electronic module E.

As shown in FIG. 7 , when the user wishes to remove the electronic module E from the server S, the user applies force to the buckle 20, so that the hook portion 231 of the second buckle portion 23 of the buckle 20 separates from the hook portion 141 of the first buckle portion 14 of the power-assisted buckle 10 to release the power-assisted buckle 10. Then, when the user rotates the power-assisted buckle 10 from the locked position to the unlocked position, the second groove wall 1212 of the force-applying buckle portion 12 of the power-assisted buckle 10 abuts against the plane wall 31 of the locking member 30. The user continues to apply force F to the handle portion 11 of the power-assisted buckle 10, so that the force-applying buckle portion 12 of the power-assisted buckle 10 is engaged with the plane wall 31 of the locking member 30 by the lever action. A force F’ is applied to the locking member 30, and the locking member 30 generates a reaction force F’ of equal magnitude but opposite direction on the power-assisting fastener 10. The torque generated by the reaction force F’ on the hinge 13 is equal in magnitude but opposite in direction to the torque generated by the user applying force F to the handle 11, so the power-assisting fastener 10 does not rotate. However, the direction of the reaction force F’ is the same as the direction of the force F applied by the user to the handle 11 of the power-assisting fastener 10, thereby increasing the force applied to move the electronic module E out of the server S. Therefore, the reaction force F’ generated by the locking member 30 on the power-assisting fastener 10 generates auxiliary force for the electronic module E to move toward the opening O in the slot SL.

The server module lock plug-in and pull-out assist structure of the present invention rotates the rotatable assist lock to the locked position, and the latch makes the assist lock to be positioned at the locked position and the clamp stops the assist lock, so as to generate a lock for the electronic module. When the handle is applied to rotate the assist lock from the locked position to the unlocked position, the force-applying lock portion of the assist lock abuts against the clamp, so that the clamp applies a reaction force to the assist lock, and provides a force to remove the electronic module from the slot, so as to help the user remove the electronic module from the server. The plug-in and pull-out operation can also be easily performed for connectors with a large plug-in and pull-out force.

The above detailed description of the preferred specific embodiments is intended to more clearly describe the features and spirit of the present invention, but is not intended to limit the scope of the present invention by the preferred specific embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent application for the present invention.
