Abstract

A screw-free mobile hard disk box has a spring sheet added to the lower cover, and its two ends extend downward and are fixed to the lower cover, so that an elastic bridge section is formed in the center, and the bridge section extends a buckling portion toward the edge of the lower cover. When the upper cover and the lower cover are combined, the bridge section can press against the upper cover to keep the upper cover and the lower cover in a combined state, thereby preventing the upper cover from being separated from the lower cover. Therefore, the mobile hard disk box can be fixed without screws.

Description

Screw-free mobile hard disk box

technical field

The invention relates to a mobile hard disk box used for installing hard disks, in particular to a screw-free mobile hard disk box.

Background technique

The mobile hard disk has a built-in 2.5-inch small hard disk. Using the internal transfer method, through such as USB or IEEE1394 connectors, the computer system can be directly connected to the outside without using internal IDE or SATA connectors. Greatly improve the convenience of use. And because of its small size, easy portability, and high mobility, and the capacity of 2.5-inch hard drives has jumped to the era of large capacity, mobile hard drives have become the most popular products in portable storage devices.

The mobile hard disk mainly uses the mobile hard disk box to install and accommodate the 2.5-inch small hard disk. The mobile hard disk box contains an external shell and an internal circuit board. However, the shells on the market are all locked by screws. Fixing, although screws are also a common fixing method, it is impossible for ordinary users to carry a screwdriver with them. When disassembling and assembling, its convenience is greatly reduced, which violates the purpose of the convenience of mobile hard disks.

Detailed ways

According to the screw-free mobile hard disk box disclosed in the present invention, please refer to FIG. 1 , which is a three-dimensional exploded schematic view of the screw-free mobile hard disk box of the present invention.

The screw-free mobile hard disk box disclosed by the present invention includes an upper cover 40, a lower cover 10, a circuit board 20, and a shrapnel 30. The upper cover 40 and the lower cover 10 roughly have the same shape, and can be combined with each other for Accommodate hard disks such as 25-inch small hard disks. The circuit board 20 is installed on one side of the lower cover 10. As shown in FIG. SATA (Serial ATA), SCSI (Small Computer System Interface) and other hard disk connection interfaces can be used to form an electrical connection with the hard disk, and the connection slot 22 is various connection interfaces such as USB or IEEE 1394 for users The hard disk is accessed by an external direct connection.

Please refer to FIG. 2B and FIG. 2C , which are schematic diagrams of the shrapnel assembly of the screw-free mobile hard disk enclosure of the present invention.

The elastic piece 30 is installed on one side of the lower cover 10 , as shown in the figure, is installed on the same side as the circuit board 20 , of course, it can also be installed on the other side. The two ends of the elastic piece 30 extend downward toward the lower cover 10 to extend out the fixing part 31, and are fixed on the lower cover 10; because they are installed on the same side as the circuit board 20, they can directly pass through the circuit board 20, and use screws, bolts, etc. Fixing, of course, can also be fixed by means of welding or gluing.

Due to the fixed support of the fixed parts 31 at the two ends of the shrapnel 30, the central part forms a suspended bridging section 32, which has elasticity towards the direction of the upper cover 40. In other words, if the bridging section 32 of the shrapnel 30 is downwardly When the lower cover 10 is pressed, the bridging section 32 will have a certain degree of elasticity to return to the original state after being released. And the bridging section 32 is approximately in the center, toward the edge of the lower cover 10 (that is, on the side of the connecting slot 22 of the circuit board 20), a buckling portion 33 extends, in other words, the buckling portion 33 is for snapping. Cover 40, therefore, the bridging section 32 extends out of the fastening portion 33 towards the edge of the accommodating space 50 (see FIG. 5A ) formed by combining the upper cover 40 and the lower cover 10, so that the fastening portion 33 can be leaned against The edge of loam cake 40.

Please refer to FIG. 3 , which is a schematic diagram of the combination of the upper cover and the lower cover of the screw-free mobile hard disk box of the present invention.

The edge of the upper cover 40 has a protrusion 41, and the edge of the lower cover 10 has a corresponding slide groove 11, so that the upper cover 40 and the lower cover 10 can be tightly sealed; The opening 12 of the chute 11 of 10 is vertically installed downwards (see Fig. 4A), until the projection 41 touches the bottom of the opening 12 of the chute 11, then the upper cover 40 and the lower cover 10 are relatively horizontally slid, and the replacement In other words, as shown in the figure, move the upper cover 40 to the right relative to the lower cover 10, so that the protrusion 41 of the upper cover 40 slides into the slot 13 of the chute 11 of the lower cover 10 (see Fig. 4B), because the height of the slot 13 is approximately equal to the height of the protrusion 41, therefore, when the protrusion 41 enters the slot 13, it can only slide along the slot 13, that is, the upper cover 40 can only slide relative to the lower The cover 10 slides left and right.

The upper cover 40 continues to slide to the right until the protrusion 41 abuts against the end of the slot 13. At this time, please refer to FIG. 33 will be pressed and deformed downwards to generate an upward elastic force, pressing against the upper cover 40 so that the upper cover 40 is maintained at this position and combined with the lower cover 10 .

Therefore, after the upper cover 40 and the lower cover 10 are combined, an accommodating space 50 (see FIG. 5A ) can be formed therein, and the hard disk 60 can be accommodated therein (see FIG. 5B ). When it needs to be disassembled, it is only necessary to push the upper cover 40 in the opposite direction, in other words, to slide toward the left side in the drawing, and the force required is to overcome the fastening portion 33 against the upper cover 40 resistance, and the hard disk 60 can be easily disassembled without screws or additional tools. Certainly, the above-mentioned fixing method between the upper cover 40 and the lower cover 10 can be easily changed, which is only described according to the drawings, and is not limited to only this combination.

On the other hand, please refer to FIG. 6 , which is a schematic diagram of another embodiment of the screw-free mobile hard disk enclosure of the present invention.

In this embodiment, on the bridging section 32 of the elastic piece 30, a protruding snap button 34 is added, and the upper cover 40 has a corresponding through fixing hole 42, so that it can be combined with the upper cover 40 and the lower cover 10. Finally, the snap button 34 is snapped into the fixing hole 42 (see FIG. 7 ), which can also achieve the effect of preventing the upper cover 40 from detaching from the lower cover 10 . When detaching is required, the upper cover 40 can be slid relative to the lower cover 10 to be detached by simply pressing the locking button 34 to disengage from the range of the fixing hole 42 .

Therefore, the screw-free mobile hard disk box disclosed in the present invention can only be fixed horizontally by the upper cover and the lower cover, and the engaging part is pressed against the upper cover with the engaging spring, or the engaging elastic has a The protruding snap button is matched with the upper cover and has a through fixing hole, which can prevent the upper cover from detaching from the lower cover; at the same time, when detaching, it is only necessary to push the upper cover hard to overcome the elasticity of the locking part due to pressing against the upper cover The hard disk can be easily disassembled and assembled without screws or tools, and a screw-free mobile hard disk box can be achieved.

Although the present invention is disclosed above with the aforementioned preferred embodiments, it is not intended to limit the present invention. Anyone skilled in this art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore The scope of protection of the present invention should be defined by the claims.
