Description

Locking devices, electronic equipment housings and server systems

This application relates to the field of server technology, specifically to a locking device, an electronic equipment housing and a server system.

At present, when installing components in a server, the server module (including related components such as display cards, hard drives, and server motherboards) is usually installed on a bracket first, and then the bracket with the integrated server module is inserted into the server case. The rapid installation and removal of the module bracket is crucial to improving the quality and operation and maintenance efficiency of the entire machine. It is urgent to provide a locking device that can quickly realize the installation and removal of the module and the server case.

This application provides a locking device to solve the problem of fast installation and removal of modules and server boxes.

The embodiment of the present application provides a locking device, which includes a housing and a locking mechanism. The locking mechanism includes a handle, a locking piece and an unlocking structure. The handle is pivoted on the housing and can rotate between a locking state and an unlocking state relative to the housing; when the handle is in the unlocking state, the first end of the handle is connected to the locking piece; when the handle is in the locking state, the first end of the handle is movably connected to the locking piece, and the second end of the handle is engaged with the unlocking structure. The third end of the locking piece includes a first engaging portion, and the first engaging portion is used to cooperate with a groove on the housing of the server. The housing has a first accommodating space and a mounting groove; the first accommodating space is used to accommodate the handle; the locking member can be slidably installed in the mounting groove so that the first clamping part can extend out of or away from the groove.

In this locking device, when the handle is in a locked state, the handle is accommodated in the first accommodation space, the second end of the handle cooperates with the unlocking structure, the first end of the handle is connected to the locking piece, and the first clamping portion of the locking piece extends out of the mounting slot. When the locking device is inserted into the box of the server, the locking piece moves in the mounting slot under the action of an external force, so that the first clamping portion is accommodated in the mounting slot. When the handle is in an unlocked state, the handle is located outside the first accommodation space, the second end of the handle does not cooperate with the unlocking structure, the first end of the handle is connected to the locking piece, and the first clamping portion of the locking piece is accommodated in the mounting slot. When the locking device is inserted into the box, there is no need to distinguish whether the handle is in the locked state or the unlocked state, which can reduce the damage to the server and the locking device caused by improper operation.

In some embodiments of the present application, the locking member has a travel cavity, and the first end of the handle can move in the travel cavity. When the handle is in a locked state, the friction of the movement of the locking member on the handle can be reduced.

In some embodiments of the present application, the third end of the locking member further has a step portion, and the step portion is used to contact the server housing in a first direction, and the first direction is the sliding direction of the locking member in the mounting slot. When the locking device is inserted into the server housing, the distance that the step portion protrudes from the locking device is greater than the gap between the locking device and the housing, so that the locking device can fit tightly with the housing.

In some embodiments of the present application, the unlocking structure includes a first elastic member, the first elastic member is provided with a clamping portion, and the second end of the handle is provided with a second clamping portion, and the clamping portion is used to clamp with the second clamping portion. The second clamping portion of the handle cooperates with the clamping portion of the first elastic member. When the handle is in a locked state, the clamping portion of the first elastic member is released from the matching relationship with the second clamping portion, so that the handle and the unlocking structure are released from the locking relationship, and the handle is in an unlocked state.

The handle structure of this type of locking device is simple and takes up little space.

In some embodiments of the present application, the unlocking structure further includes an unlocking button, which is connected to the first elastic member and is located outside the first accommodation space, so that pressing the unlocking button can deform the first elastic member and release the clamping connection with the handle.

In some embodiments of the present application, the locking device further includes a torsion spring. The handle includes a pivot, the handle is pivotally connected to the housing via the pivot, the torsion spring is sleeved on the pivot, and the torsion spring has an elastic force to drive the handle to rotate to the unlocked state. After pressing the unlock button, the locking device can use the elastic force of the torsion spring to make the handle structure automatically pop out of the first accommodation space.

In some embodiments of the present application, a second elastic member is further included, one end of the second elastic member is connected to the fourth end of the locking member, and the other end of the second elastic member is connected to the side wall of the mounting slot facing the locking member; when the handle is in the unlocked state, the elastic force of the second elastic member is less than the elastic force of the torsion spring.

When the installation locking device is inserted into the box, the external force causes the locking piece to move in the installation slot so that the first clamping part is accommodated in the installation slot. At this time, the second elastic piece is in a compressed state. When the installation locking device moves to the groove position of the server box, the second elastic piece releases the elastic potential energy and applies an elastic force to the locking piece so that the first clamping part of the locking piece extends out of the installation slot and cooperates with the groove of the box. At this time, the locking device and the server box are locked together. When the unlocking structure is pressed, the elastic force of the torsion spring is greater than the elastic force of the second elastic piece, so that the elastic force of the torsion spring can bounce the handle out of the first accommodation space.

In some embodiments of the present application, the handle further includes a stopper, and the housing includes a stopper mating portion, and the stopper mating portion is used to cooperate with the stopper to limit the rotation of the handle relative to the housing, thereby reducing damage to the locking device caused by excessive movement of the handle.

The embodiment of the present application also provides an electronic device housing, including a housing, a bracket and a locking device as described in the above embodiment, wherein the locking device is connected to the bracket, the housing is provided with a groove, and when the bracket is inserted into the housing, the first clamping part cooperates with the groove.

The embodiment of the present application also provides a server system, including a data access device and an electronic device housing as described in the above embodiment, wherein the data access device is mounted on the bracket.

When the data access device needs to be installed in the box of the server system, the data access device is first installed in the first accommodation space of the bracket, and after the hard disk drive is fixed, the locking device is then inserted into the box. At this time, it is not necessary to consider whether the handle is in a locked state or an unlocked state. If the handle is in an unlocked state, the handle is pressed down so that the handle and the unlocking structure cooperate to complete the installation of the data access device. When the data access device needs to be taken out of the box of the server system, the unlocking structure is pressed, and after the handle and the unlocking structure are released from the matching relationship, the torsion spring releases the elastic potential energy, and the handle is quickly ejected from the outside of the accommodation space by the elastic force. At this time, the first clamping part of the locking member and the groove of the box are released from the matching relationship, and the locking device is taken out, and then the data access device can be taken out. The server system can realize the quick installation and removal of locking devices and boxes.

The following is a further description of the embodiments of this application in conjunction with the attached figures.

Please refer to FIG. 1 and FIG. 7 for an embodiment of the present application to provide a locking device 100 for quickly realizing the installation and removal of a data access device 303 and a housing 301 of a server system 300. The server system 300 generally includes a display card, a data access device 303, a motherboard and other related components. The data access device 303 includes a data storage device such as a hard disk drive and an optical disk drive.

Please refer to FIG. 2 and FIG. 3 together. The locking device 100 includes a housing 20 and a locking mechanism 10. The locking mechanism 10 includes a handle 13, a locking member 11 and an unlocking structure 12. The handle 13 is pivoted on the housing 20, and the handle 13 can switch between the locked and unlocked states by rotating. The handle 13 has a first end 13a and a second end 13b opposite to each other. When the handle 13 is in the unlocked state, the first end 13a of the handle 13 is connected to the locking member 11. When the handle 13 is in the locked state, the first end 13a of the handle 13 is movably connected to the locking member 11, and the second end 13b of the handle 13 is engaged with the unlocking structure 12. The locking member 11 has a third end 11a and a fourth end 11b opposite to each other. The third end 11a of the locking member 11 includes a first clamping portion 111. When the locking device 100 is inserted into the housing 301 of the server system 300, the first clamping portion 111 is used to cooperate with the groove 3011 (FIG. 6) on the housing 301 of the server system 300, thereby realizing the assembly of the locking device 100 and the server system 300. The housing 20 includes a first side wall 21, a second side wall 22, a third side wall 23, and a fourth side wall 24. The first side wall 21 and the third side wall 23 extend along a first direction X and are disposed opposite to each other along a second direction Y. The second side wall 22 and the fourth side wall 24 extend along the second direction Y and are disposed opposite to each other along the first direction X. The first side wall 21, the second side wall 22, the third side wall 23, and the fourth side wall 24 enclose a first accommodation space 25. When the handle 13 is in a locked state, the handle 13 is accommodated in the first accommodation space 25. The housing 20 further includes a mounting groove 26. The locking member 11 can be slidably mounted in the mounting groove 26 so that the first clamping portion 111 can extend out of or away from the groove 3011 on the housing 301 of the server system 300. The first direction X is the sliding direction of the locking member 11 in the mounting groove 26, and the second direction Y is the extending direction of the axis of the pivotal rotation of the handle 13 relative to the housing 20.

When the handle 13 is in a locked state, the handle 13 is accommodated in the first accommodation space 25, the second end 13b of the handle 13 cooperates with the unlocking structure 12, the first end 13a of the handle 13 is connected to the locking member 11, and the first clamping portion 111 of the locking member 11 extends out of the mounting slot 26. When the locking device 100 is inserted into the box 301 of the server system 300, the locking member 11 moves in the mounting slot 26 under the action of an external force, so that the first clamping portion 111 is accommodated in the mounting slot 26. When the handle 13 is in an unlocked state, the handle 13 is located outside the first accommodation space 25, the second end 13b of the handle 13 does not cooperate with the unlocking structure 12, the first end 13a of the handle 13 is connected to the locking member 11, and the first clamping portion 111 of the locking member 11 is accommodated in the mounting slot 26. When the locking device 100 is inserted into the box 301, it is not necessary to distinguish whether the handle 13 is in a locked state or an unlocked state, which can reduce damage to the server system 300 and the locking device 100 caused by improper operation.

Please refer to Figure 3. The locking member 11 has a travel cavity 113, and the first end 13a of the handle 13 can move in the travel cavity 113. When the handle 13 is in the locked state, the locking device 100 is inserted into the box 301, and the locking member 11 moves in the mounting groove 26 along the first direction X, so that the first clamping portion 111 of the locking member 11 is accommodated in the mounting groove 26, which can reduce the contact between the handle 13 and the locking member 11 during the movement of the locking member 11, and reduce the friction caused by the movement of the locking member 11 on the handle 13. In one embodiment, the first clamping portion 111 has a guide surface 1111, so that when the locking device 100 contacts the side wall of the box 301, the first clamping portion 111 can be guided to move relative to the box 301 in the first direction X, so as to guide the first clamping portion 111 to enter the box 301.

In one embodiment, the third end of the locking member 11 further includes a step portion 112, and the step portion 112 protrudes from the locking device 100 along the first direction X by a distance greater than the gap between the locking device 100 and the box 301. When the locking device 100 is inserted into the box 301, the locking device 100 can be closely matched with the box 301 along the first direction X, thereby reducing the gap between the locking device 100 and the box 301.

In one embodiment, the unlocking structure 12 includes a first elastic member 122, and a snap-fitting portion 1221 is provided on the first elastic member 122. The second end 13b of the handle 13 has a second snap-fitting portion 133, and the snap-fitting portion 1221 is used to snap-fit with the second snap-fitting portion 133. When the second snap-fitting portion 133 of the handle 13 cooperates with the snap-fitting portion 1221 of the first elastic member 122, the snap-fitting relationship between the first elastic member 122 and the second snap-fitting portion 133 is released when the handle 13 is in a locked state, so that the handle 13 is released from the unlocking structure 12, and the handle 13 is in an unlocked state.

In one embodiment, the second clamping portion 133 is a convex portion, the first elastic member 122 is a spring sheet, and a through slot is provided on the spring sheet, that is, the clamping portion 1221 is a through slot. When the handle 13 is in a locked state, the convex portion is clamped in the through slot. When an external force is applied to the spring sheet, the spring sheet can be deformed, so that the spring sheet moves away from the convex portion of the handle 13. After the convex portion moves away from the through slot of the first elastic member 122, the handle 13 and the unlocking structure 12 are released. The handle 13 of this locking device 100 has a simple structure and occupies a small space.

In one embodiment, the unlocking structure 12 further includes an unlocking button 121, which is connected to the first elastic member 122. The unlocking button 121 is located outside the first accommodating space 25, so that pressing the unlocking button 121 can deform the first elastic member 122 and release the clamping connection with the handle 13.

In one embodiment, the locking device 100 further includes a torsion spring 132. The handle 13 includes a pivot 131, and the torsion spring 132 is sleeved on the pivot 131. The torsion spring 132 is used to drive the handle 13 to pop out of the first accommodation space 25. Specifically, the handle 13 is provided with the pivot 131, and the handle 13 is connected to the housing 20 via the pivot 131, thereby realizing the rotation connection between the handle 13 and the housing 20, so that the handle 13 performs a flipping movement in the first accommodation space 25 of the housing 20. Of course, the handle 13 turns toward the opening direction of the first accommodating space 25. When the handle 13 is not turned, the handle 13 can be stored in the first accommodating space 25 of the housing 20, and the second end 13b is fixedly connected with the unlocking structure 12. When the handle 13 is turned outward at a certain angle, the handle 13 is unfolded to the outside of the first accommodating space 25 of the housing 20, and the staff can conveniently grasp it.

The handle 13 is provided with a through hole 136, and one end of the torsion spring 132 is installed in the through hole 136. The through hole 136 limits the displacement of the torsion spring 132. The torsion spring 132 has elastic force along the circumferential direction of the pivot 131, and when the handle 13 is flipped to the outside of the first accommodating space 25, the torsion spring 132 is in a natural state, that is, it is not compressed. When the handle 13 is accommodated in the first accommodation space 25, the torsion spring 132 is in a compressed state and accumulates a certain amount of elastic potential energy. However, due to the clamping of the unlocking structure 12 on the handle 13, the torsion spring 132 cannot release energy and remains in a compressed state. Only when the unlocking structure 12 unlocks the handle 13, the torsion spring 132 can begin to reset and quickly pop the handle 13 out of the first accommodation space 25 by elastic force.

Please refer to Figure 2 and Figure 4. Further, a stopper 134 is provided on the handle 13, and a stopper matching portion 27 is provided on the first side wall 21 and/or the third side wall 23. When the unlocking structure 12 is pressed to unlock the handle 13, the torsion spring 132 releases elastic potential energy, and the handle 13 is quickly bounced out of the first accommodating space 25 by elastic force. The stopper matching portion 27 cooperates with the stopper 134 to limit the displacement of the handle 13, which can reduce the damage of the locking device 100 caused by excessive movement of the handle 13.

In addition, when the locking device 100 is pulled out from the server system 300 case, the stopper mating portion 27 can be used as a support point for pulling out, so that the user can apply force from the outside of the first accommodating space 25 to pull the locking device 100 out of the server system 300 case.

In one embodiment, the handle 13 is provided with a pull ring 135, so that the user can apply force from the outside to move the handle 13 upward out of the first accommodation space 25.

Referring to FIG. 2 , in one embodiment, the locking device 100 further includes a second elastic member 114, one end of the second elastic member 114 is connected to the fourth end 11b of the locking member 11, and the other end of the second elastic member 114 is connected to the side wall of the mounting slot 26 facing the locking member 11. When the handle is in the unlocked state, the elastic force of the second elastic member 114 is less than the elastic force of the torsion spring 132. When the locking device 100 is installed and inserted into the box 301, the external force causes the locking member 11 to move in the mounting groove 26 so that the first clamping portion 111 is accommodated in the mounting groove 26. At this time, the second elastic member 114 is in a compressed state. When the locking device 100 moves to the position of the groove 3011 of the box 301 of the server system 300, the second elastic member 114 releases the elastic potential energy and applies an elastic force to the locking member 11 so that the first clamping portion 111 of the locking member 11 extends out of the mounting groove 26 and cooperates with the groove 3011 of the box 301. At this time, the locking device 100 and the box 301 are locked together. When the unlocking structure 12 is pressed, the torque of the torsion spring 132 is greater than the elastic force of the second elastic member 114, so that when the elastic force of the torsion spring 132 bounces the handle 13 out of the first accommodation space 25, the handle 13 drives the locking member 11 to move in the mounting slot 26 along the first direction X to unlock.

Specifically, the second elastic member 114 is a compression spring, which is sleeved on the fourth end of the locking member 11. When the locking device 100 is inserted into the box 301, the external force causes the locking member 11 to move in the first direction X in the mounting groove 26 so that the first clamping portion 111 is accommodated in the mounting groove 26. At this time, the compression spring is in a compressed state, and the compression spring accumulates a certain amount of force. When the locking device 100 is installed and moved to the groove 3011 of the box 301, the compression spring releases the elastic potential energy, exerting an elastic force on the locking member 11 in the opposite direction of the first direction X so that the first clamping portion 111 cooperates with the groove 3011 of the box 301, so that the locking device 100 and the server system 300 are locked together.

Please refer to Figures 5 to 7. Another aspect of the embodiment of the present application provides an electronic device housing 310, including a housing 301, a bracket 302 and a locking device 100 as in the above embodiment. The locking device 100 is connected to the bracket 302, and the bracket 302 is connected to the housing 20. The housing 301 is provided with a groove 3011. When the bracket 302 is inserted into the housing 301, the first clamping portion 111 cooperates with the groove 3011.

Please refer to Figures 5 to 7. Another aspect of the embodiment of the present application provides a server system 300, including a data access device 303 and an electronic device housing 310 as in the above embodiment. The data access device 303 is mounted on a bracket 302. The bracket 302 has a second accommodation space 3021. The second accommodation space 3021 is used to install and fix the data access device 303, which can reduce the shaking of the data access device 303 during the insertion of the locking device 100 into the box 301. The first clamping portion 111 and the groove 3011 cooperate to realize the installation and fixation of the data access device 303 and the box 301.

Please refer to Figures 5, 7 and 8 in combination. Another aspect of the embodiment of the present application provides a data access device module 400, including the data access device 303, the bracket 302 and the locking device 100 in the above embodiment, the data access device 303 is connected to the second accommodating space 3021 of the bracket 302, and the bracket 302 is connected to the housing 20. When the data access device 303 needs to be loaded into the box 301, the data access device 303 is first installed in the second accommodation space 3021 of the bracket 302. After the data access device 303 is fixed, the locking device 100 is then inserted into the box 301. At this time, it is not necessary to consider whether the handle 13 is in a locked state or an unlocked state. If the handle 13 is in an unlocked state, the handle 13 is pressed down so that the handle 13 cooperates with the unlocking structure 12, and the installation of the data access device 303 is completed.

When the data access device 303 needs to be taken out of the box 301 of the server system 300, the unlocking structure 12 is pressed, and the handle 13 is released from the unlocking structure 12. The torsion spring 132 releases the elastic potential energy, and the handle 13 is quickly ejected from the outside of the first accommodating space 25 by the elastic force. At this time, the first clamping part 111 of the locking member 11 is released from the groove 3011 of the box 301, and the locking device 100 is taken out, and then the data access device 303 is taken out. The server system 300 can realize the rapid installation and removal of the locking device 100 and the box 301.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit them. Although this application is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalent ones.
