The embodiment of the application provides an electronic device, and various types of commonly used electronic devices are used, such as a server, a desktop computer, a notebook computer, a mobile phone and the like.

In this embodiment, the type of the electronic device is not limited, and in order to vividly describe the electronic device provided in the embodiment of the present application, the electronic device may be taken as an example of a server.

The embodiment of the application provides electronic equipment, referring to fig. 1-5, the electronic equipment comprises a main board 1, wherein a plurality of slots 12 are arranged on the main board 1; the expansion cards 4 are arranged in an array manner, each expansion card 4 is installed in the corresponding slot 12, the notch-shaped clamping grooves of the expansion cards 4 face to the same side and are approximately positioned on the same straight line, and the locking structure arranged between the main board 1 and the expansion cards 4 can enable the main board 1 and the expansion cards 4 to be locked or unlocked.

Because of its functional requirements, the bus and interface standard (PERIPHERAL COMPONENT INTERFACE EXPRESS, PCIE) module is a key hardware configuration, and the Riser card generally refers to a board card such as a function expansion card 4, a switch card, etc. inserted into a PCIE interface provided on the motherboard 1. In order to meet the requirements of high-speed communication and processing of complex graphic data of a server, the types, the numbers and the sizes of the boards are generally increased, the weight is also increased along with the increase of the quality of the boards, and the boards are easier to separate from interfaces of the boards in vibration test of electronic equipment. That is, a locking mechanism is needed to facilitate quick unlocking of the cards and reliable support of the cards in the server.

The embodiment of the application provides a locking structure, referring to fig. 1-5, the locking structure is arranged between a main board 1 and an expansion card 4 of electronic equipment, the locking structure comprises a support frame 2 and a locking piece 3, the support frame 2 is fixedly arranged on the main board 1, and a semi-open accommodating space is formed on one side of the support frame 2 away from the main board 1; the locking element 3 is movably arranged in the semi-open accommodating space and can move to a first position or a second position along a first direction relative to the support frame 2 so as to enable the locking element 3 and the expansion card 4 to be in a locking position or a free position, and the locking element 3 is used for locking or unlocking the expansion card 4 and the main board 1; the locking piece 3 is provided with a first clamping part 31 at one end close to the expansion card 4 and is used for clamping with a second clamping part 41 of the expansion card 4; wherein the first direction is parallel to the length direction of the expansion card 4.

Specifically, the support frame 2 in the locking structure is formed with a semi-open accommodating space on one side facing away from the main board 1, so as to be used for carrying the locking element 3 movably arranged in the semi-open accommodating space, and since the locking element 3 can move relative to the support frame 2 in the length direction of the expansion card 4 to enable the expansion card 4 to be in a locking position or a free position, the locking or unlocking of the expansion card 4 by the locking element 3 can be realized, and when the locking element 3 is locked with the expansion card 4, the expansion card 4 is not easy to be separated from the slot 12 in a vibration test. Wherein, one locking element 3 may have a plurality of first clamping parts 31 facing the plurality of expansion cards 4 plugged on the main board 1, when the locking element 3 moves to the locking position, referring to fig. 3, each first clamping part 31 on the locking element 3 may be simultaneously clamped with the corresponding second clamping part 41 of each expansion card 4, so that one locking element 3 may simultaneously lock the plurality of expansion cards 4; correspondingly, when the locking element 3 moves to the unlocking position, referring to fig. 2, each first clamping portion 31 on the locking element 3 can be simultaneously separated from the corresponding second clamping portion 41 of each expansion card 4, so that one locking element 3 simultaneously unlocks a plurality of expansion cards 4, and compared with the case that each expansion card 4 is correspondingly provided with a locking structure to realize unlocking or locking, the assembly and disassembly of a plurality of expansion assemblies can be facilitated. In addition, the support reliability of the expansion card 4 can be improved by properly increasing the sizes of the support frame 2 and the locking piece 3 which are parallel to the plane on which the main board 1 is positioned and selecting the support frame 2 and the locking piece 3 with higher strength, and the like, so that the locking piece 3 and the expansion card 4 are in the locking position.

It should be noted that the specific structural form and the mounting manner of the support frame 2 in the embodiment of the present application are not limited. For example, a screw hole is formed in the main board 1, a through hole is formed in a position, corresponding to the screw hole, of the support frame 2, and the support frame 2 is fixedly connected with the main board 1 through a screw; or the supporting frame 2 avoids the main board 1 and is fixedly connected with the bottom wall of the chassis on one side of the main board 1 away from the supporting frame 2, which is not particularly limited. In addition, the form of the locking element 3 movably provided on the support frame 2 is not limited, and for example, a limiting structure for limiting the movement of the locking element 3 on the side away from the support frame 2 may be provided on the support frame 2, and a guiding structure for guiding the locking element 3 along the length direction of the expansion card 4 may be provided so that the locking element 3 can move relative to the support frame 2 in the length direction of the expansion card 4. In this case, a stop structure can be provided on the support frame 2 along the movement path of the locking element 3, so that the locking element 3 can be moved into a locking position or a free position relative to the support frame 2. Wherein the locking position may correspond to a first position and the corresponding free position may correspond to a second position.

The specific structure of the first engaging portion 31 at one end of the locking element 3 and the second engaging portion 41 of the expansion card 4 is not limited. For example, the first clamping portion 31 may be an elastic clamping protrusion, and the second clamping portion 41 may be a clamping hole adapted to be clamped with the elastic clamping protrusion, where the clamping hole may be a notch-shaped clamping hole formed by the expansion card 4 itself, as shown in fig. 1. When the locking piece 3 moves to a first position along a first direction relative to the support frame 2, the elastic clamp is in protruding fit and stretches into the clamping hole so that the locking piece 3 and the expansion card 4 are in a locking position; when the locking element 3 moves to the second position along the first direction, for example, when the locking element 3 moves away from the expansion card 4 to the second position along the first direction, the elastic clamping protrusion can be pulled out of the clamping hole, so that the locking element 3 and the expansion card 4 are in a free position.

For example, referring to fig. 4, the first engaging portion 31 of the locking member 3 facing one end of the expansion card 4 is a convex engaging portion, and as shown in fig. 1, the second engaging portion 41 of the expansion card 4 is a notch-shaped engaging hole formed therein. Referring to fig. 2 to 5, when the protruding engagement of the locking element 3 extends into the engaging hole of the expansion card 4, since the expansion card 4 is inserted into the slot 12 of the motherboard 1 along the third direction, i.e. perpendicular to the plane of the motherboard 1, i.e. the expansion card 4 is easy to deviate from the plane of the motherboard 1 in the third direction and to be separated from the slot 12 of the motherboard 1, the locking element 3 and the supporting frame 2 are engaged with each other by the first engaging portion 31, and since the locking element 3 and the supporting frame 2 are at the locking position, i.e. the relative position of the locking element 3 with respect to the motherboard 1 along the third direction is fixed, in the vibration test or the daily use of the electronic device, the first engaging portion 31 can generate a force for restricting the separation of the expansion card 4 along the third direction, so that the expansion card 4 is not easy to be separated, and the supporting and limiting capability of the locking element 3 on the expansion card 4 can be lifted.

The number of the first clamping portions 31 is not limited, and preferably, as shown in fig. 6 and 8, the number of the first clamping portions 31 provided on the locking member 3 is at least two, and at least two first clamping portions 31 are provided in one-to-one correspondence with the second clamping portions 41 of the expansion cards 4, so that when the locking member 3 moves to the first position or the second position along the first direction relative to the support frame 2, the locking position between the expansion cards 4 and the locking member 3, or the free position between the expansion cards 4 and the locking member 3 can be maintained. Therefore, the locking structure can be used for quickly disassembling and assembling the expansion pieces.

For example, referring to fig. 9 and 10, the support frame 2 is provided with a guide groove 23, the locking member 3 is provided with a guide member 33 slidably engaged with the guide groove 23, and the extending direction of the guide groove 23 is parallel to the first direction; the guide groove 23 serves to guide the movement of the locking element 3 in a first direction relative to the support frame 2 into a first position or into a second position. Referring to fig. 5, the guide groove 23 is directly formed on a side wall of the support frame 2 facing the locking element 3, and the locking element 3 is provided with a guide member 33 adapted to the guide groove 23, and the locking element 3 can be slid with respect to the support frame 2 by manually operating an operating portion 34 located on the locking element 3, such as pulling or pushing the locking element 3 in a first direction.

In some embodiments, referring to fig. 7 and 9, a protrusion 32 is provided on a side wall of the locking element 3 facing the supporting frame 2, a first clamping groove 21 and a second clamping groove 22 matched with the protrusion 32 are provided on the supporting frame 2, and the first clamping groove 21 and the second clamping groove 22 are arranged at intervals along the first direction; when the locking piece 3 is positioned at the first position, the protrusion 32 is matched and clamped in the first clamping groove 21, so that the relative position of the locking piece 3 and the support frame 2 is fixed; when the locking element 3 is located at the second position, the protrusion 32 is engaged in the second slot 22, so that the relative positions of the locking element 3 and the support frame 2 are fixed. The position of the dashed line in fig. 7 and 9 allows for a clearer contrast between the projections 32 in fig. 7 to 9, which are each switched from the first locking groove 21 to the second locking groove 22, i.e. from the free position to the locking position between the locking element 3 and the expansion card 4.

It should be noted that, the material of the locking element 3 is not limited, and preferably, the body of the locking element 3 is a deformation portion with a certain deformation capability, for example, referring to fig. 6 and 8, the locking element 3 has a first elastic portion and a second elastic portion that can deform, so that the locking element 3 can deform by a certain amount toward the contact surface of the locking element 3 and the supporting frame 2. The protrusion 32 may be an elastic protrusion with a certain deformability, the guide member 33 may be disposed on the first elastic portion on a side facing the support frame 2, the protrusion 32 is disposed on the second elastic portion on a side facing the support frame 2, when the protrusion 32 is engaged in the first clamping groove 21, i.e. the locking member 3 is at the first position, when the locking member 3 is required to move from the first position to the second position, the locking member 3 may be lifted toward the side facing away from the support frame 2 at the first position, and meanwhile, under the action of the limiting structure limiting the locking member 3 along the side facing away from the support frame 2, the locking member 3 may not be completely separated from the support frame 2, but deformation portions on the locking member 3, such as at least one of the first elastic portion and the second elastic portion, may be deformed toward the side facing away from the support frame 2, so that the protrusion 32 may be separated from the first clamping groove 21 under the action of an external force, and further may be moved to the second position under the action of the external force, and when the locking member 3 moves to the second position, the protrusion 32 is engaged in the second clamping groove 22 to keep the locking member 3 at the second position.

In other embodiments, referring to fig. 8 and 10, at least two first limiting members 24 are disposed on a side of the support frame 2 facing the locking member 3, and the first limiting members 24 are respectively disposed on two opposite sides of the support frame 2 along the second direction, and are used for limiting the movement of the locking member 3 relative to the support frame 2 along the second direction, and each first limiting member 24 has a limiting surface facing the locking member 3, and is used for limiting the movement of the locking member 3 away from the limiting surface along the third direction; the second direction is perpendicular to the first direction and parallel to the plane of the main board 1, and the third direction is perpendicular to the plane of the main board 1. This facilitates movement of the locking element 3 in a first direction only in a plane relative to the support frame 2 to prevent movement of the locking element in other directions relative to the support frame 2 so that the locking element 3 can be moved to the first or second position more accurately.

The specific structure of the first limiting member 24 is not limited, for example, the first limiting member 24 has a stop protrusion 32 or a stop slot, and the distance between the stop protrusions 32 or the stop slots on the first limiting member 24 on two opposite sides of the support frame 2 along the second direction can exactly coincide with the extending length of the locking member 3 along the second direction, so as to enable the two opposite first limiting members 24 to abut against and limit the locking member 3 to move along the second direction.

Further, as an example, referring to fig. 10, each first stopper 24 includes a first stopper 241 and a first protrusion 242, the first stopper 241 protrudes from a side of the support frame 2 facing the locking element 3, and at least two first stoppers 241 respectively abut on two opposite side walls of the locking element 3 in the second direction for restricting the movement of the locking element 3 relative to the support frame 2 in the second direction; the first protruding part 242 is connected to one side of the first stopping part 241 away from the supporting frame 2, and the limiting surface is positioned on one side of the protruding part facing the locking piece 3; the limiting surface and a side wall of the support frame 2 facing the locking element 3 are respectively abutted with two opposite side walls of the locking element 3 along the third direction, so as to be used for limiting the movement of the locking element 3 relative to the support frame 2 along the third direction. Specifically, the distance between the limiting surface and the side wall of the support frame 2 facing the locking element 3 is matched with the thickness of the locking element 3 along the third direction, so that the limiting surface and the side wall of the support frame 2 facing the locking element 3 are respectively abutted with two opposite side walls of the locking element 3 along the third direction, and the limiting locking element 3 moves relative to the support frame 2 along the third direction.

For example, referring to fig. 10, the side of the support frame 2 facing the locking element 3 is provided with a second limiting element 25, the second limiting element 25 being provided on the side of the support frame 2 facing the locked element 3; the second limiting member 25 includes a second stop portion 251 and a second protruding portion 252, the second stop portion 251 protrudes from one side of the support frame 2 facing the locking member 3, and the second stop portion 251 is used for limiting the locking member 3 to move to the locking position along the first direction; the second protruding portion 252 is connected to a side of the second stopping portion 251 away from the supporting frame 2, and two opposite side walls of the second protruding portion 252 opposite to the supporting frame 2 are respectively abutted against two opposite side walls of the locking piece 3 along a direction perpendicular to the plane of the main board 1, so as to be used for limiting the movement of the locking piece 3 relative to the supporting frame 2 along the direction perpendicular to the plane of the main board 1. The second stop portion 251 of the second limiting member 25 may be disposed to limit the movement range of the locking member 3 along the first direction, and the disposed position of the second stop portion 251 on the locking member 3 may be adjusted according to the actual situation, so that after the first clamping portion 31 on the locking member 3 is clamped with the second clamping portion 41 on the expansion board, the second stop portion 251 is just abutted with the locking member 3 to limit.

In some embodiments, referring to fig. 5, 9 and 10, the side of the support frame 2 facing away from the locking element 3 is provided with a boss 26, the boss 26 is provided with a mounting hole 261, the edge of the main board 1 is provided with a connecting hole 11, and the support frame 2 is fastened on the main board 1 by passing the fastener 5 through the mounting hole 261 and the connecting hole 11 in sequence. Here, the boss 26 is provided so that the support frame 2 is prevented from being attached to the main body at a portion where the boss 26 is removed, thereby preventing interference with the functional device on the main board 1. Here, the kind of the fastener 5 is not limited, for example, the fastener 5 is a screw, the connection hole 11 is a screw hole, and the screw passes through the mounting hole 261 and the screw hole in order to tighten the support frame 2 on the main board 1. In addition, the arrangement of the connection holes 11 at the edge of the main board 1 can reduce the influence of the opening of the connection holes 11 on the main board 1.

Continuing, referring to fig. 4, in the first direction, the front projection of the fastener 5 on the plane of the main board 1 is located outside the front projection of the first engaging portion 31 on the plane of the main board 1. In this way, the fastener 5 can be arranged to avoid the first clamping portion 31, so as to avoid interference with the fastener 5 during the movement of the locking member 3 and facilitate the disassembly of the support frame 2. In addition, after the boss 26 is attached to the motherboard 1, an accommodating space is formed inside for allowing a cable of the electronic device to pass through. Thus, the internal space of the electronic device can be fully utilized.
