When the carrier body 100 is to be mounted on the assembly side panel 10, one of the buckle blocks 112 of the assembly part 110 is firstly inserted into the first buckle chute 12 from the first release section 13 of the first buckle chute 12 . Then let the carrier body 100 slide away from the top edge 11 of the assembly side plate 10, and when the other buckle block 112 of the assembly part 110 moves to the second release section 17 of the second buckle chute 15, let it slide again. Another buckling block 112 of the part to be assembled 110 enters the second buckling chute 15 from the second release section 17 of the second buckling chute 15 . Then, continue to slide the carrier body 100 to the bottom in a direction away from the top edge 11 of the assembled side panel 10 . In this way, the assembly of the carrier body 100 and the assembling side plate 10 can be completed, and when the carrier body 100 is installed on the assembling side plate 10, the buffer structure 111 of the assembling part 110 of the carrier body 100 leans against the assembling side plate 10 The positioning groove 21. In addition to the positioning effect provided by the positioning groove 21, the elastic deformation capability of the buffer structure 111 can also reduce the vibration amplitude transmitted from the self-assembled side plate 10 to the carrier body 100, thereby improving the protection effect and protection of the storage device 40. The operation quality and lifespan of the storage device 40 are improved. In addition, since the positions of the release sections 13, 17 of the two buckle slide grooves 12, 15 are different, misinstallation and disassembly operations can be avoided.

The bearing part 130 is connected to the assembly part 110 and is not parallel to the assembly part 110 . The carrying part 130 is used for carrying the storage device 40 to drive the storage device 40 to move.

The pivoting portion 120 is not parallel to the assembling portion 110 , and the pivoting portion 120 and the bearing portion 130 are respectively located on opposite sides of the assembling portion 110 in the thickness direction T1 of the assembling portion 110 . The pivot portion 120 has a pivot hole 121 .

The buckle part 300 is movably mounted on a side of the handle 200 away from the buckle protrusion 220 , and has a buckle protrusion 310 . The buckle protrusion 310 is used to buckle into the buckle slot 22 of the other assembly side panel 10'. The return member 350 is, for example, a compression spring, and is sandwiched between the buckle 300 and the handle 200, so that the spring force of the reset member 350 drives the buckle 300 to normally engage with the buckle groove 22 of the other assembly side plate 10'.

Please also refer to Figures 5 to 7. FIG. 5 is a schematic plan view of the carrier body 100 in FIG. 4 . FIG. 6 is a partially enlarged schematic view of FIG. 5 . FIG. 7 is a partially enlarged schematic view of FIG. 6 .

In this embodiment, the included angle θ1 between the pivoting portion 120 and the assembling portion 110 can be determined according to the size of the pushing convex portion 210 and the locking convex portion 220, as long as the pushing convex portion 210 and the locking convex portion 220 do not prevent It only needs to prevent the loading and unloading of the storage device 40 . Therefore, if the pushing convex portion 210 and the locking convex portion 220 become larger, the included angle θ1 between the pivoting portion 120 and the assembling portion 110 can be increased. Conversely, if the pushing protrusion 210 and the locking protrusion 220 become smaller, the included angle θ1 between the pivoting portion 120 and the assembly portion 110 can be reduced. For example, the included angle θ1 between the pivoting portion 120 and the assembling portion 110 may be between 10 degrees and 45 degrees, and the swing head has a buffer function.

In addition, the distance L1 from the pivot hole 121 of the pivot portion 120 to the center point of the buffer structure 111, the protrusion height H of the buffer structure 111, the length L2 of the buffer structure 111, and the thickness T of the assembly portion 110 can be determined according to the storage device 40. Anti-vibration needs to be adjusted.

See Figures 8 through 14. 8 to 14 are disassembly schematic diagrams of the storage device carrier 30 in FIG. 1 .

As shown in FIG. 8 and FIG. 9 , the storage device 40 is installed on the assembly side panel 10 through the storage device carrier 30 , and the electrical connector 41 of the storage device 40 is installed on the electrical connector 60 of the circuit board 50 . In addition, the buckle convex part 220 of the handle 200 and the buckle convex part 310 of the buckle part 300 are respectively engaged with the two buckle grooves 22 of the two assembly side plates 10, 10', so that the handle 200 is located at the cover position (as shown in FIG. 8 shown) to fix the storage device carrier 30 on the two assembly side panels 10, 10'.

When the carrier body 100 is mounted on the assembling side panel 10 , the buffer structure 111 of the assembling part 110 of the carrier body 100 abuts against the positioning groove 21 of the assembling side panel 10 . In addition to the positioning effect provided by the positioning groove 21 , the elastic deformation capability of the buffer structure 111 can also reduce the vibration amplitude transmitted from the self-assembled side plate 10 to the carrier body 100 .

Conversely, when the storage device 40 is to be taken out, the assembler can push the buckle 300 along the direction A to release the buckle relationship between the buckle protrusion 310 of the buckle 300 and the buckle groove 22 of the assembly side plate 10'. Next, as shown in FIGS. 10 and 11 , the assembler rotates the handle 200 along the direction B to open the handle 200 from the closed position. At this stage, the opening rotation angle θ3 of the handle 200 is about 90 degrees, that is, the included angle between the handle 200 at this stage and the reference line X when the handle 200 is in the closed position is about 90 degrees. During the rotation process of the handle 200, the operation of pushing the pushing convex portion 210 of the handle 200 against the top edge 11 of the assembly side plate 10 drives the storage device 40 and the storage device carrier 30 to move along the direction C for a short distance and let The electrical connector of the storage device 40 is detached from the electrical connector 60 of the circuit board 50 . The electrical connector of the storage device 40 is detached from the circuit board 50 After the electrical connector 60, the handle 200 of the storage device carrier 30 is pulled along the direction C, so that the storage device carrier 30 is driven to move along the direction C. When the buffer structure 111 of the part to be assembled 110 abuts against the top edge 11 of the assembled side plates 10, 10', since the buffer structure 111 is supported by the assembled side plates 10, 10', it will not fall in the direction C. Therefore, at this time The assembler can position the storage device carrier 30 in the half-drawn position without holding it by hand.

It should be noted that if the rotation angle θ3 of the handle 200 is maintained at about 90 degrees, the buckle protrusion 220 of the handle 200 may block the sliding-in path and the sliding-out path of the storage device 40 . However, in this embodiment, because the pivoting portion 120 is designed to be inclined relative to the assembly portion 110 , the handle 200 can continue to rotate, so that the buckling protrusion 220 of the handle 200 moves out of the sliding path of the storage device 40 . Detailed description As shown in Figure 12 and Figure 13, the assembler continues to turn the handle 200 along the direction D, and the rotation angle θ4 of the handle 200 is about 180 degrees, which is the reference line between the handle 200 and the handle 200 at the cover position at this stage The included angle of X is about 180 degrees. In this way, the buckle protrusion 220 of the handle 200 can be moved out of the slide-out path of the storage device 40 so as to prevent the handle 200 from blocking the slide-in path and the slide-out path of the storage device 40 . In addition, as shown in FIG. 14 , the assembler can continue to rotate the handle 200 along the direction E, and the rotation angle θ5 of the handle 200 is about 240 degrees, which is the reference line X between the handle 200 and the handle 200 at the cover position at this stage. The included angle is about 240 degrees. That is to say, the rotation angle range of the handle 200 in this embodiment can be selectively between 0 degrees and 240 degrees.
