[ detailed description ] embodiments

Referring to fig. 1 to 3, an embodiment of a hard disk tray of the present invention is adapted to be mounted on a housing 8 and carry a hard disk 9, and the hard disk tray includes a frame 1, a handle 2 and a switch 3. As shown in fig. 1, in the present embodiment, a plurality of housings 8 can be mounted adjacent to each other on a chassis 7, and as shown in fig. 2, each housing 8 can accommodate a plurality of hard disk holders, such as two hard disk holders (only one hard disk holder is shown in fig. 2 for example) and a plurality of hard disks 9 (not shown in fig. 2) respectively placed on the hard disk holders. Since the structure and the mounting manner of each hard disk tray are the same as those of the housing 8, the detailed structure and the mounting manner thereof will be described as follows.

Before describing in detail, in the present embodiment, as shown in fig. 2, the hard disk tray, the housing 8 and the hard disk 9 are in the spatial coordinates of a height direction D1, a length direction D2 and a width direction D3 perpendicular to each other, but the actual directions are still determined by the current installation situation and are not limited to the description of the present embodiment.

Referring to fig. 2 and 3, in the present embodiment, the housing 8 is substantially rectangular, and the housing 8 forms a mounting opening 81 for inserting and extracting the hard disk tray, and has two side walls 82, a rear wall 83, a top wall 84 and a bottom wall 85 connecting the side walls 82 and the rear wall 83, and a first connection port 86 disposed on an inner surface of the rear wall 83. Each of the sidewalls 82 has an inner surface 821, an outer surface 822 opposite to the inner surface 821, and a locking hole 823 through the inner surface 821 and the outer surface 822 adjacent to the mounting opening 81. The hard disk 9 has a second connection port 91 electrically connected to the first connection port 86, when the hard disk 9 is inserted into the housing 8 along with the hard disk tray and pushed into the rear end of the housing 8, the second connection port 91 of the hard disk 9 can be electrically connected to the first connection port 86, so that a computer system (not shown) electrically connected to the first connection port 86 can access the hard disk 9 through the first connection port 86.

Referring to fig. 2 and 3, the frame 1 is detachably inserted into the housing 8 through the mounting opening 81 and is used for accommodating the hard disk 9. In this embodiment, the frame 1 includes a generally rectangular carrier 11 for carrying the hard disk 9, and a support frame 12 connected to a front side of the carrier 11.

Referring to fig. 3 and 4, the handle 2 is pivotally fixed to a front side 121 of the frame 1, and the handle 2 includes a handle body 21 and a holder 22. More specifically, the handle body 21 has a pivot end 23 pivoted to one end of the front side 121 of the frame 1, and a moving end 24 rotating around the pivot end 23. In the embodiment, the fixer 22 is connected to the pivot end 23, and the fixer 22 and the handle body 21 are integrally formed and made of a plastic material with lower cost than metal, so as to reduce the production cost. The pivot end 23 has a base structure 231 and two protruding shaft structures 232 respectively disposed on two opposite sides of the base structure 231 and extending in the height direction D1 in a generally cylindrical shape, and the protruding shaft structures 232 are correspondingly disposed through the

shaft holes

122, 123 formed on the supporting frame 12, so that the handle 2 can rotate relative to the supporting frame 12.

Referring to fig. 3 and 4, the fixing device 22 has a resilient arm 25, a locking end 26, a stop 27, a first position-limiting arm 28 and a second position-limiting arm 29. The elastic arm 25 is bent and extended outward from the pivot end 23, so that when the front side 121 of the frame 1 enters the mounting opening 81 of the housing 8, the elastic arm 25 is pressed and retracted by the sidewall 82 of the housing 8 adjacent to the retainer 22. More specifically, the elastic arm 25 has a first elastic arm 251, a second elastic arm 252 and a third elastic arm 253, two opposite ends of the first elastic arm 251 are respectively connected to the pivot end 23 and one end of the second elastic arm 252, two opposite ends of the third elastic arm 253 are respectively connected to the locking end 26 and the other end of the second elastic arm 252, and form a generally U-shape together with the first elastic arm 251 and the second elastic arm 252.

In the present embodiment, the first elastic arm 251 is thicker than the second elastic arm 252 and the third elastic arm 253, so as to enhance the connection strength between the anchor 22 and the pivot end 23, and prevent the anchor from breaking due to long-term bending. And because the elastic arm 25 has elasticity and has a margin of transverse expansion, when the width errors of different chassis 8 with the same size are different, the hard disk bracket can be tightly contacted with the side wall 82 of the chassis 8 after the front side 121 of the hard disk bracket enters the mounting opening 81 of the chassis 8 by the compression elasticity of the elastic arm 25, and can be mounted on different chassis 8 with different width errors, so that the width error of the chassis 8 has higher tolerance, the use elasticity and the convenience of the hard disk bracket are further improved, and the purchase cost of replacing the hard disk bracket or the chassis due to the width error of the chassis 8 can be saved. Therefore, when the front side 121 of the frame 1 enters the mounting opening 81 of the housing 8, the third elastic arm 253 is pressed by the sidewall 82 to retract toward the first elastic arm 251.

Referring to fig. 3 to 5, the locking end 26 protrudes from the end of the elastic arm 25 and corresponds to the locking hole 823. In this embodiment, the locking end 26 extends from the end of the third elastic arm 253 not connected to the second elastic arm 252 to a direction away from the first elastic arm 251. When the front side 121 of the frame 1 enters the mounting opening 81 of the housing 8 and the locking end 26 moves to a position corresponding to the locking hole 823, the third elastic arm 253 releases the pressure and resets to allow the locking end 26 to enter and be retained in the locking hole 823, and the stop portion 27 extends from the connection point of the third elastic arm 253 and the locking end 26 along the height direction D1. More specifically, the stopping portion 27 has two stopping structures 271, the stopping structures 271 are respectively located at two opposite ends of the connection portion of the third elastic arm portion 253 and the clamping end portion 26, each stopping structure 271 is a positioning protrusion protruding outward along the height direction D1, and the surface of the stopping structure 271 is rounded, although the surface of the stopping structure 271 is not mainly rounded. When the locking end 26 enters the locking hole 823, the stopping structures 271 abut against the inner surface 821 of the side wall 82 to limit the locking end 26 to be positioned in the locking hole 823, even if the locking end 26 cannot protrude from the locking hole 823, the gap between the casing 8 and the casing 8 shown in fig. 1 can be further reduced, and further more space is provided for the casing 7, so that the number of hard disks 9 to be mounted can be increased.

Referring to fig. 3 to 5, the first position-limiting arm 28 has a first position-limiting section 281 extending from the first elastic arm 251 toward the third elastic arm 253, and a second position-limiting section 282 extending from the end of the first position-limiting section 281 toward a direction away from the second elastic arm 252. The second position-limiting arm 29 has a third position-limiting section 291 extending from the third elastic arm 253 toward the first elastic arm 251 and extending between the second position-limiting section 282 and the pivot end 23, and a fourth position-limiting section 292 extending from the end of the third position-limiting section 291 toward the second elastic arm 252 and having an end located between the first elastic arm 251 and the second position-limiting section 282. In this embodiment, the second position-limiting segment 282 is spaced apart from the pivot end 23 by a first distance D1 to limit the movement of the third position-limiting segment 291 within the first distance D1, so as to limit the displacement of the third elastic arm 253 in the length direction D2, thereby preventing any one of the first elastic arm 251, the second elastic arm 252 and the third elastic arm 253 from being broken due to excessive deformation. Similarly, the second position-limiting segment 282 and the first resilient arm portion 251 are also spaced apart by a second distance D2, so as to limit the movement of the fourth position-limiting segment 292 in the second distance D2, and further limit the displacement of the third resilient arm portion 253 in the width direction D3, and prevent any one of the first resilient arm portion 251, the second resilient arm portion 252 and the third resilient arm portion 253 from being broken due to excessive deformation in the other direction. Therefore, by disposing the first position-limiting arm 28 and the second position-limiting arm 29 in the space defined by the elastic arm 25 and generating the mutual position-limiting effect, not only the excessive deformation of the elastic arm 25 can be avoided, but also the space-saving effect can be achieved. However, the above-mentioned limit structure is not limited to being disposed on the first elastic arm 251 and the third elastic arm 253.

Referring to fig. 3 and 5, the switch member 3 is disposed at the other end of the front side 121 of the frame 1 and is engaged with the moving end 24, and the switch member 3 releasably clasps the moving end 24 to fix the frame 1 in the housing 8. In this embodiment, the structure of the switch member 3 is conventional, and therefore, will not be described herein.

It should be noted that the manner of limiting the locking end 26 in the locking hole 823 is not limited by the stop portion 27, but in another embodiment, the effect of limiting the locking end 26 in the locking hole 823 can be achieved by the combination of the elastic design of the elastic arm 25, the displacement of the third elastic arm 253, and the width of the locking end 26.

Referring to fig. 6 and 7, before the hard disk tray is inserted into the housing 8, the moving end 24 is first forced to rotate in the counterclockwise direction to move the holder 22 between the supporting frame 12 and the handle body 21, and then as shown by the arrow parallel to the length direction D2 in fig. 6 and referring to fig. 7, when the front side 121 of the frame 1 enters the mounting opening 81 of the housing 8, the third elastic arm 253 of the holder 22 is pressed by the side wall 82 to retract toward the first elastic arm 251, and the pivot end 23 abuts against the front side edge of the side wall 82. Then, as shown in fig. 5, the moving end 24 is driven to rotate clockwise to make the locking end 26 tightly abut against the front wall of the locking hole 823, so that the second connection port 91 is tightly connected to the first connection port 86, and the moving end 24 is locked by the switch 3 to fix the frame 1 in the housing 8.

To sum up, the hard disk bracket of the above embodiment is retained in the locking hole 823 while being secured to the locking hole 823 by the locking end 26 of the fixer 22, so as to reduce the gap between the chassis 8 and the chassis 8, and further provide more space for the chassis 7 to increase the number of hard disks 9 to be installed. Therefore, the object of the present invention can be achieved.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
