The first side 31c of the frame 31 is opposite to an expresscard slot in the chassis.

The trigger 32 is movably connected to the frame 31. The trigger 32 projects relative to the first end 31a of the frame 31. The expansion card mounting bracket 34 and the linkage 33 are both located in the frame 31. The linkage 33 is connected to the trigger 32 and the expansion card mounting bracket 34, respectively. The expansion card mounting bracket 34 is used for connecting the expansion card 20. Fig. 4 is a schematic view of an operation process of an expansion card installation device provided in an embodiment of the present disclosure. As shown in fig. 4, the linkage mechanism 33 is used to bring the expansion card mounting bracket 34 closer to or away from the first side 31c of the frame 31 under the action of the trigger 32, so that the insertion part 21 of the expansion card 20 extends or retracts relative to the first side 31c of the frame 31.

In the installation of the expansion card, the expansion card may be connected to the expansion card mounting bracket 34, and then the expansion card installation device is inserted into the chassis, and the trigger 32 is operated at the first end 31a of the frame 31. The expansion card mounting rack 34 is driven by the linkage mechanism 33, and then the expansion card is driven by the expansion card mounting rack 34 to approach the first side 31c of the frame 31, so that the insertion part 21 of the expansion card 20 extends out of the first side 31c of the frame 31, and is inserted into an expansion card slot inside the chassis.

Fig. 5 is a schematic structural diagram of a frame according to an embodiment of the present disclosure. As shown in fig. 5, the frame 31 has a rectangular parallelepiped shape, and includes a bottom plate 311, two end plates 312, and two side plates 313. The bottom plate 311 is rectangular, and the two end plates 312 are respectively located at two ends of the bottom plate 311 in the length direction and are connected to the bottom plate 311. The two side plates 313 are respectively connected with two opposite sides of the bottom plate 311, and the bottom plate 311, the two end plates 312 and the two side plates 313 enclose a receiving groove for receiving the expansion card.

A first opening 312a may be provided at the first end 31a of the frame 31 for the trigger 32 to protrude relative to the first end 31 a; the first side 31c of the frame 31 may have a second opening 313a for the insertion part 21 of the expansion card 20 to protrude.

In some examples, the frame 31 may omit some of the above structures, such as the end plate 312 at the second end 31 b.

As shown in fig. 3, the linkage mechanism 33 includes a plurality of links. The plurality of connecting rods are sequentially hinged, and part of the plurality of connecting rods is movably connected with the frame 31.

The linkage 33 may be disposed in a receiving groove defined by the frame 31. The plurality of links are sequentially hinged to form a linkage mechanism, so that when the trigger 32 is operated, the expansion card mounting frame 34 is driven to move along a predetermined track through interaction among the plurality of links.

As shown in fig. 3, the plurality of links includes a first translation link 331, a second translation link 332, a first transmission link 333, and a second transmission link 334.

The first translational link 331 is movably connected to the frame 31 and can move toward or away from the first end 31a of the frame 31. The second translation link 332 is located on a side of the first translation link 331 near the first side 31c of the frame 31. The second translating link 332 is movably connected to the frame 31 and can move toward or away from the first side 31c of the frame 31. The expansion card mounting bracket 34 is coupled to the second translating link 332 to move with the second translating link 332.

One end of the first transmission link 333 is hinged to the trigger 32, and the other end of the first transmission link 333 is hinged to the first translation link 331. One end of the second transmission link 334 is hinged to the first translation link 331, and the other end of the first transmission link 333 is hinged to the second translation link 332.

The first transmission link 333 connects the trigger 32 and the first translation link 331, and when the trigger 32 is operated, the trigger 32 drives the first translation link 331 to move through the first transmission link 333, so that the first translation link 331 is close to or far away from the first end 31a of the frame 31. During the movement of the first translating link 331, the second translating link 332 is driven by the second transmission link 334, so that the second translating link 332 is close to or far away from the first side 31c of the frame 31, and the expansion card mounting bracket 34 is driven to be close to or far away from the first side 31c of the frame 31. Under the action of a plurality of connecting rods, the movement of the trigger piece 32 is converted into the movement of the expansion card mounting frame 34, and the insertion and extraction actions of the expansion card are completed.

As shown in fig. 3, the first translation link 331 has a first guide sliding slot 331a, and the first guide sliding slot 331a extends in a length direction of the first translation link 331. A first connecting member 3111 is connected to the frame 31, and the first connecting member 3111 is disposed in the first guide sliding slot 331 a.

The movement direction of the first translational link 331 is limited by the cooperation of the first guide sliding groove 331a and the first connector 3111, so that the movement direction of the first translational link 331 is along the length direction thereof.

The second translating link 332 has a second guide runner 332a, and the second guide runner 332a extends along the length of the second translating link 332. A second connector 3112 is connected to the frame 31, and the second connector 3112 is located in the second guide sliding groove 332 a.

The movement direction of the second translational link 332 is limited by the engagement of the second guide sliding groove 332a and the second connector 3112, so that the movement direction of the second translational link 332 is along the length direction thereof.

Illustratively, the first connector 3111 and the second connector 3112 are screws, and are connected to the bottom plate 311 of the frame 31. The first and second link parts 3111 and 3112 serve not only to restrict the moving direction of the first and second translational links 331 and 332 but also to connect the first and second translational links 331 and 332 to the frame 31.

The first translational link 331 has two first guide sliding chutes 331a, and first connecting pieces 3111 are disposed in the two first guide sliding chutes 331 a; the second translation link 332 has two second guide sliding grooves 332a, and a second connector 3112 is disposed in each of the two second guide sliding grooves 332 a.

Optionally, the expansion card mounting device further includes a locking member 35. A locking member 35 is connected to the frame 31, the locking member 35 being for locking the linkage mechanism 33 when the plug portion 21 of the expansion card 20 is retracted with respect to the first side 31c of the frame 31.

Because the operation trigger 32 can drive the expansion card to move, so that the plugging portion 21 of the expansion card 20 extends and retracts relative to the first side 31c of the frame 31, when the plugging portion 21 of the expansion card 20 retracts relative to the first side 31c of the frame 31 by using the locking member 35, the linkage mechanism 33 is locked, so as to avoid that the plugging portion 21 of the expansion card 20 extends relative to the first side 31c of the frame 31 and presses a circuit board and other structures inside the chassis due to misoperation when the plugging portion 21 of the expansion card 20 is not aligned with an expansion card slot in the process of plugging and pulling out the expansion card, and the structures such as the plugging portion 21 of the expansion card 20 and the circuit board are damaged.

The locking member 35 is used to lock any one of the plurality of links, thereby locking the linkage mechanism 33. The locking member 35 may be provided differently depending on the link to which the locking member 35 locks. As an example, the lock member 35 in the embodiment of the present disclosure locks the link mechanism 33 by locking the second translation link 332.

As shown in fig. 3, the locking member 35 includes a locking portion 351, an unlocking portion 352, and an elastic reset portion 353.

The locking part 351 is located on a side of the first translation link 331 near the first side 31c of the frame 31. The locking part 351 is movably connected with the frame 31, and the locking part 351 is used for locking the second translation link 332.

The elastic restoring portion 353 is connected to the locking portion 351 and the frame 31, respectively. An unlocking portion 352 is connected to the locking portion 351, the unlocking portion 352 extending at least partially relative to the first side 31c of the frame 31. The unlocking portion 352 is used to bring the locking portion 351 into motion by an external force to unlock.

In this example, the locking part 351 may be close to or distant from the first end 31a of the frame 31 by the unlocking part 352 and the elastic restoring part 353. When the unlocking part 352 is acted by external force, the locking part 351 is driven to be close to the first end 31a of the frame 31, the linkage mechanism 33 is unlocked, and the elastic resetting part 353 stores energy; upon removal of the external force, the elastic restoring portion 353 releases energy to move the locking portion 351 away from the first end 31a of the frame 31, and the locking portion 351 locks the linkage mechanism 33.

When the linkage mechanism 33 is unlocked, the unlocking portion 352 may move by being directly pushed by an operator, or the unlocking portion 352 may contact the chassis, so that the unlocking portion 352 drives the locking portion 351 to move for unlocking. See the following text for details.

Fig. 6 is a schematic structural diagram of a second translational link according to an embodiment of the disclosure. As shown in fig. 6, an end of the second translation link 332 near the first side 31c of the frame 31 has a stepped surface 3321.

A notch 332b is formed in an end of the second translating link 332 near the first side 31c of the frame 31, and the notch 332b is located on a side of the second translating link 332 near the first end 31a of the frame 31, thereby forming a stepped surface 3321 at the end of the second translating link 332.

Fig. 7 is a schematic structural diagram of a locking portion and an unlocking portion according to an embodiment of the present disclosure. As shown in fig. 7, the locking portion 351 has a catching groove 351b. As shown in connection with fig. 3, the second translation link 332 is partially located in the slot 351b. When the second translation link 332 is locked, the stepped surface 3321 abuts against the locking portion 351.

The locking portion 351 is movable toward or away from the first end 31a of the frame 31, and the movement of the locking portion 351 changes the relative position of the card slot 351b and the second translation link 332. When the unlocking portion 352 is subjected to an external force, the locking portion 351 is brought close to the first end 31a of the frame 31, and the linkage mechanism 33 is unlocked, the locking groove 351b is aligned with the end portion of the second translational link 332, and the movement of the second translational link 332 is not affected by the locking portion 351. The elastic restoring portion 353 drives the locking portion 351 to be away from the first end 31a of the frame 31, when the locking portion 351 locks the second translational link 332, the engaging groove 351b is offset from the end portion of the second translational link 332 by a certain distance, so that the step surface 3321 of the end portion of the second translational link 332 is partially positioned outside the engaging groove 351b and abuts against the locking portion 351, and thus the second translational link 332 cannot approach the first side 31c of the frame 31, and the linkage mechanism 33 is locked.

As shown in fig. 7, the locking part 351 is bar-shaped, and the unlocking part 352 is located at an end position of the locking part 351 near the first end 31a of the frame 31. The elastic restoring portion 353 is located at the other end of the locking portion 351, and the elastic restoring portion 353 may be a spring. The catching groove 351b may be located between the unlocking part 352 and the elastic restoring part 353, and a middle region of the locking part 351 is bent to form the catching groove 351b.

The locking part 351 may have a third guide chute 351a, the third guide chute 351a extending in a length direction of the locking part 351. As shown in fig. 3, a third connecting member 3113 is connected to the frame 31, and the third connecting member 3113 is located in the third guide sliding groove 351 a. The movement direction of the locking part 351 is restricted such that the movement direction of the locking part 351 is along its own longitudinal direction by the cooperation of the third guide chute 351a and the third link 3113.

Illustratively, the third connector 3113 is a screw, and the third connector 3113 is connected to the bottom plate 311 of the frame 31. The third connector 3113 not only functions to limit the movement direction of the locking part 351 but also functions to connect the locking part 351 to the frame 31.

In this example, the locking part 351 has three third guide chutes 351a, and third connectors 3113 are provided in each of the three third guide chutes 351 a.

Referring to fig. 2, the expansion card mounting bracket 34 is positioned in a receiving groove formed in the frame 31. The expansion card mounting bracket 34 is disposed opposite to the bottom plate 311 of the frame 31, and the link mechanism 33 and the locking member 35 are both located between the expansion card mounting bracket 34 and the bottom plate 311. The expansion card mounting bracket 34 is connected with the frame 31 and the linkage mechanism 33, and the expansion card mounting bracket 34 is movably connected with the frame 31 so as to move relative to the frame 31 under the drive of the linkage mechanism 33.

Illustratively, the expansion card mounting bracket 34 has a fourth guide chute 34a, and the fourth guide chute 34a extends along the moving direction of the second translation link 332, i.e., the length direction of the fourth guide chute 34a is parallel to the length direction of the second guide chute 332 a. A fourth link 3114 is connected to the frame 31, and the fourth link 3114 is located in the fourth guide chute 34 a. The fourth connector 3114 may be a screw connected to the bottom plate 311 of the frame 31. The movement of the card extender mounting bracket 34 is made more stable by the cooperation of the fourth guide sliding groove 34a and the fourth link 3114 to limit the moving direction of the card extender mounting bracket 34.

The card extender mounting bracket 34 may be plate-shaped, and a side of the card extender mounting bracket 34 remote from the linkage 33 is used to attach the card extender, such as by screwing the card extender.

As shown in fig. 3, the trigger 32 includes a handle 321. One end of the handle 321 is hinged to the frame 31, and the other end of the handle 321 is located outside the frame 31. The linkage 33 is hinged to the handle 321. In this example, the first transmission link 333 is hinged to the handle 321.

By hinging one end of the handle 321 with the frame 31, the handle 321 can be rotated, and the linkage mechanism 33 is moved by the handle 321.

As shown in fig. 3, the trigger 32 further includes a snap-in portion 322. One end of the handle 321 is hinged to the frame 31, and the clamping portion 322 is located at the other end of the handle 321 and connected to the handle 321. The engaging portion 322 is adapted to engage with or disengage from the frame 31.

The handle 321 can be locked by the engagement of the engaging portion 322 with the frame 31, and the engaging portion 322 can be separated from the frame 31 when the handle 321 needs to be operated.

In this example, one end of the clip portion 322 is hinged to the handle 321, and the other end of the clip portion 322 is hook-shaped, and the hook-shaped end is used for matching with the frame 31. A torsion spring 323 can be connected between the clamping portion 322 and the handle 321, so that the clamping portion 322 can hook the frame 31 under the action of the torsion spring 323.

As shown in fig. 5, the first end 31a of the frame 31 has a bayonet 312b, and when the engaging portion 322 engages with the frame 31, the engaging portion 322 is partially located in the bayonet 312b and engages with the end plate 312 of the frame 31, so that the handle 321 is locked. By pressing the engaging portion, the engaging portion 322 is rotated relative to the handle 321, and the hook-shaped end of the engaging portion 322 is separated from the frame 31, so that the handle 321 is unlocked. After the handle 321 is unlocked, the clamping portion 322 is driven to withdraw from the clamping opening 312b by rotating the handle 321.

As shown in fig. 3, the handle 321 further has a locking protrusion 324, and the locking protrusion 324 is located at one end of the handle 321 hinged to the frame 31. The locking protrusion 324 is used for extending out relative to the second side 31d of the frame 31 when the clamping portion 322 is clamped with the frame 31.
