Abstract

A hard disk drive holder includes a main body and a handle having a clipping member and a hook, a pivot shaft, a first elastic member, a second elastic member, a latching device having a blocking piece, and a third elastic member which are mounted to the main body. The pivot shaft is slidable from a first position to a second position. The handle is rotatably mounted to the main body via engaging with the pivot shaft. The first elastic member biases the pivot shaft tending to slide to the second position. The second elastic member biases the handle tending to rotate to open. The latching device is slidable from a third position to a forth position. The third elastic member biases the latching device tending to slide to the fourth position. When the pivot shaft is slid to the second position, the blocking member extends outward from the main body gradually. When the pivot shaft is in the second position, the hook can be operated to go over and clip the blocking piece, thereby shutting off the handle. When the pivot shaft is in the first position, the hook can not go over the blocking piece.

Description

Hard disk drive bracket

The invention relates to a hard disk drive bracket.

The hard drive bracket is used to mount the hard drive. The front end of the hard drive bracket is usually equipped with a handle. One end of the handle is rotatably mounted to the hard disk drive bracket and has a card body, and the other end of the handle is provided with a buckle. A housing for receiving a hard disk drive bracket is usually provided in the computer case. A latching slot corresponding to the handle on one side wall of the receiving portion defines a latching slot. After the hard disk drive bracket is received in the housing portion of the computer case, the handle is closed. The buckle at one end of the handle will be snapped to the front end of the hard drive bracket, and the latch body at the other end of the handle will protrude into the slot of the side wall of the receiving portion. Therefore, the hard disk drive bracket is locked in the housing portion of the computer case without coming out. However, due to manufacturing tolerances and deformation caused by the detection, the width of the accommodating portion may be inaccurate, so that the card body of the handle cannot be properly inserted into the card slot of the accommodating portion.

In order to overcome the above problems, a design of a hard disk drive bracket has appeared in the industry. This design slidably mounts the card body to the handle and provides a spring between the card body and the handle. Therefore, the card body has the ability to automatically expand and contract, thereby making up for the width error of the housing portion. However, this design has another drawback in that when the card body abuts against the side wall of the housing portion and does not protrude into the card slot, the buckle of the handle can still be snapped to the hard disk drive bracket. This may cause the user to mistakenly think that the hard disk drive bracket has been installed in place, thereby causing the hard disk drive bracket to automatically come out of the accommodating portion and causing damage to the hard disk drive when the accommodating portion is turned over.

In view of the above, it is necessary to provide a hard disk drive bracket that can compensate for the width error of the housing portion and can prompt the user whether the installation operation is completed when the hard disk drive bracket is mounted.

Referring to FIG. 4, a hard disk drive (not shown) is mounted between the first mounting arm 14 and the second mounting arm 15 of the hard disk drive bracket 8. The hard disk drive bracket 8 together with the hard disk can be loaded into the housing portion 4 of a computer case. The receiving portion 4 includes two side walls 5, 6, wherein the side wall 5 is provided with a latching groove 7. Before loading 8 into 4, the handle 30 of the hard disk drive holder 8 is first placed in an open state relative to the panel 11 of the hard disk drive holder 8 (Fig. 4 shows the handle 30 in a closed state). The hard disk drive bracket 8 is pushed into the accommodating portion 4 of the computer case, so that the hard disk drive bracket 8 is completely slid into the accommodating portion 4. The handle 30 is rotated toward the panel 11. The guiding surface 360 of the hook 36 of the handle 30 contacts and cooperates with the guiding surface 560 of the blocking piece 56 of the locking device 50, so that the locking device 50 is pushed by the handle 30 to the left side (ie, the side wall of the panel 11) The one side of the 24 slides and compresses the third elastic member 58 until the hook 36 of the handle 30 passes over the stop piece 56 of the locking device 50, and the third elastic member 58 elastically returns to push the locking device 50 to the original position. The hook 36 of the handle 30 is caught on the rear side of the stopper piece 56 of the locking device 50. Thus, the handle 30 is closed to the panel 11. At the same time, the latching body 34 of the handle 30 extends into the latching slot 7 of the side wall 5 of the receiving portion 4, and the first extending piece 31 and the second extending piece 32 of the handle 30 abut against the inner side of the side wall 5. Therefore, the hard disk drive bracket 8 is sandwiched between the two side walls 5, 6 of the accommodating portion 4, and the hard disk drive bracket 8 is locked in the accommodating portion 4 by the cooperation of the latching body 34 and the latching slot 7. Will slide out. Wherein, the elastic force of the first elastic member 80 pushes the rotating shaft 60 to the right first end hole 210 of the panel 11 and the rightmost end of the second shaft hole 220, and the handle 30 also reaches the right end of the sliding range with the rotating shaft 60. The second elastic member 90 is compressed.

Thus, the second elastic member 90 can bounce the handle 30 to rotate the handle 30 in a direction away from the panel 11 to be opened by the panel 11. The handle 30 is opened while the latch body 34 is disengaged from the latching slot 7 of the receiving portion 4. Thereby, the hard disk drive holder 8 can be pulled out from the housing portion 4. When the handle 30 is opened, the first extension piece 31 of the handle 30 abuts against the projection 212 such that the opening angle of the handle 30 is about 30 degrees.

Further, in actual production, the pitch of the side walls 5, 6 of the accommodating portion 4 may be within plus or minus 1 mm (much smaller than the length of the first shaft hole 210 and the second shaft hole 220). The handle 30 of the hard disk drive bracket 8 of the present invention can slide under the action of the first elastic member 80, thereby having the ability to compensate for the error, thereby ensuring that the latching body 34 of the handle 30 can extend into the latching slot 7 of the receiving portion 4. .

Referring to FIG. 5, if the hard disk drive bracket 8 has not completely slideed into the accommodating portion 4, the user rotates the handle 30 toward the panel 11 by hand to perform the action of closing the handle 30, and the latch body 34 of the handle 30 will be Receiving the side wall 5 of the receiving portion 4, the handle 30 is slid to the left along the elongated first shaft hole 210 and the second shaft hole 220 of the panel 11 by the rotating shaft 60, so that the rotating shaft 60 slides to the first shaft hole 210 and The leftmost end of the second shaft hole 220. This causes the hooks 36 of the handle 30 to fail beyond the stop tabs 56 of the latching device 50. The design of the elongated slot 214 of the panel 11 is such that even if the locking device 50 is manually operated to slide the sliding slot 214 to the leftmost end, the hook 36 of the handle 30 cannot pass over the blocking piece of the locking device 50. 56. Therefore, the handle 30 cannot be closed to the panel 11, so that the user can be prompted that the hard disk drive holder 8 has not been installed in place to alert the user, thereby preventing the accidental removal of the hard disk drive holder 8 from the receiving portion 4.

In other embodiments, there is a clearance fit between the shaft 60 and the sleeve 70, and an interference fit between the shaft 60 and the third shaft hole 313 and/or the fourth shaft hole 324 of the handle 30.

In other embodiments, the first elastic member 80 can be a torsion spring, and the two legs of the torsion spring act on the sleeve 70 and the panel 11, respectively. At the same time, a protrusion like the boss 221 is protruded from the panel 11 to position the torsion spring.

In other embodiments, the sleeve 70 can be omitted and the guide post 71 can be directly extended by the shaft 60. In addition, the guide post 71 can be further omitted, while the cross section of the portion of the rotating shaft 60 located in the elongated first shaft hole 210 and/or the second shaft hole 220 is designed to be rectangular, so that the rotating shaft 60 itself can only slide. Can't turn. After the guide post 71 is omitted, the first elastic member 80 can be positioned by other means. For example, a sleeve having a through hole fixed to the panel 11 can be disposed at the original guide post 71, and then the first elastic member 80 can be received. The through hole of the sleeve.

In other embodiments, the second resilient element 90 can be a spring. Both ends of the spring are used to abut against the panel 11 and the handle 30, respectively.

In other embodiments, there may be only one third elastic element 58. The third resilient member 58 can also be a tension spring. The two ends of the tension spring are respectively connected to the locking device 50 and the portion of the panel 11 on the right side of the locking device 50, and the boss 57 of the locking device 50 can be omitted.

In other embodiments, one of the latch bodies 34 on the handle 30 can be omitted. The hook 36 of the handle 30 can be only one.
