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. Thus, 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 handle's buckle can still be snapped onto the hard drive bracket. This will cause the user to mistakenly think that the hard disk drive bracket has been installed, so that when the storage unit is turned over, the hard disk drive bracket automatically comes out of the accommodating portion and the hard disk drive is damaged.

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.

A hard disk drive bracket includes a body and a handle that is openably closed to the body, the handle is provided with a buckle device, the buckle device is buckled to the body to close the handle, and the handle is provided with at least one card The body of the hard disk drive includes a rotating shaft, a first elastic member and a second elastic member. The rotating shaft is slidably mounted on the body, and the rotating shaft is slid from a first position to a second position. The latching body of the handle is gradually extended from one side of the body. When the rotating shaft is in the second position, the latching device can be buckled to the body. When the rotating shaft is in the first position, the latching device is not Snapped to the body, the handle is rotatably mounted to the body through the rotating shaft, the first elastic element acts between the body and the rotating shaft such that the rotating shaft tends to slide to the second position, the second elastic element Acting between the body and the handle causes the handle to tend to open.

The handle of the hard disk drive bracket of the present invention can slide under the elastic action of the first elastic member, thereby making up for the width error of the receiving portion of the hard disk drive bracket of the present invention. In addition, since the buckle device can be disengaged from the buckle when the handle is in the first position, the second elastic member bounces the handle, thereby being able to prompt the user whether the installation action is indeed completed.

Further, in actual production, the width between the side walls 5, 6 of the accommodating portion 4 may have an error 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 fully slid into the accommodating portion 4, the user rotates the handle 30 toward the body 10 by hand to perform the action of closing the handle 30, and the latch body 34 of the handle 30 will 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 body 10 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 snap block 56 of the snap device 50 to not protrude into the body 10 Buckle hole 240. Thus, when the user's hand is disengaged from the handle 30, the handle 30 will automatically bounce off under the action of the second resilient member 90, causing the handle 30 to rotate away from the body 10. Thus, the user can be prompted that the hard disk drive holder 8 has not been securely locked in the accommodating portion 4, thereby preventing the hard disk drive holder 8 from accidentally coming out of the accommodating portion 4.

In the present embodiment, when the rotating shaft 60 slides to the leftmost end of the first shaft hole 210 and the second shaft hole 220, the rotating shaft 60 is located at the first position, and the rotating shaft 60 slides to the most of the first shaft hole 210 and the second shaft hole 220. At the right end, the shaft 60 is in the second position.

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 lead legs of the torsion spring act on the sleeve 70 and the body 10 respectively. At the same time, a protrusion like the boss 221 is protruded from the body 10 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 body 10 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 member 90 can be a spring. The bomb Both ends of the spring are used to abut the body 10 and the handle 30, respectively.

In other embodiments, the third resilient element 40 can be a spring. Both ends of the spring abut against the operating portion 54 of the snap device 50 and the handle 30, respectively. The third elastic member 40 can also be a tension spring. The two ends of the tension spring are respectively pulled on the buckle portion 53 of the buckle device 50 and the portion of the handle 30 located on the right side of the buckle portion 53.

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

In other embodiments, the snap device 50 can be secured to the handle 30 such that the snap device 50 cannot be rotated while the third resilient member 40 is omitted. Thus, when the handle 30 is normally closed, the guiding surface 560 of the snap block 56 of the snap device 50 can interact with the corresponding end of the second connecting wall 24 of the body 10, thereby causing the handle 30 to slide to the left, so that the snap block 56 is snapped into the snap hole 240 of the second connecting wall 24 beyond the corresponding end of the second connecting wall 24. Alternatively, when the handle 30 is normally closed, the handle 30 can be pulled to the left so that the snap block 56 can be snapped into the snap hole 240 beyond the corresponding end of the second connecting wall 24.
