Description

External hard disk box with shockproof and dustproof

The utility model relates to an external hard disk box.

At present, the structure of the known hard disk (as shown in Figure 4) is composed of a hard disk A1 and a read-write head A2 in the hard disk A. Generally, when not in use, the hard disk A1 is stable. When the hard disk is in use, the motor in hard disk A will drive hard disk A1 to rotate at a high speed, and the high-speed rotation of hard disk A1 will form an airflow inside hard disk A, and the airflow will make The read-write head A2 floats away from the surface of the hard disk A1, and then uses magnetic induction to convert the data on the hard disk A1 into signals by the read-write head A2, and transmits the signals to the memory or arithmetic unit; Therefore, when the hard disk A1 is running, if the hard disk A is shaken or shaken, the buoyancy of the read-write head A2 floating away from the surface of the hard disk A1 will be disturbed or destroyed; The direct knocking and contact with the surface of the hard disk A1 will further cause the surface of the hard disk A1 to be cracked or scratched, so that the data recorded on this area can no longer be read or written and damaged.

As shown in Figures 4 and 5, it consists of a hard disk A, a base B and a top cover C. The hard disk A is placed in the base B, and the connection port A3 of the hard disk A is connected to the The outside of the rear edge of the base B is connected to the power connection port A4 on the left side of the connection port A3 to the outside of the rear edge of the base B with a power cord B2, and then the upper cover C is covered on the base B to form an independent body. However, in the conventional external hard disk box, there is generally no protective structure to protect the hard disk drive A in the box from vibration or shaking. Therefore, this kind of hard disk mechanism is designed to avoid damage due to vibration. The magnetic area of the hard disk A1 can only be placed on the table fixedly, and cannot be moved or carried freely, otherwise it is easy to be damaged by vibration and cause damage to the hard disk. For passive or portable use, the probability of vibration is tens or even hundreds of times higher than that of ordinary household computers, so it is necessary to add shockproof and dustproof to the external hard disk drive box.

In view of this, the purpose of this utility model is to provide a kind of external hard disk box with shockproof and dustproof. Effect.

The purpose of this utility model is achieved in this way: a shockproof and dustproof external hard disk box is composed of an upper cover, a hard disk and a base, and the hard disk is placed in the base, and the signal cable is used and the power cord to electrically connect the base to the power port of the connecting port of the hard disk, and the upper cover and the base are sealed and connected into one body. There are several soft pads.

The signal cable is made of flexible circuit board.

The power socket at the rear edge of the base is a coaxial socket.

The power socket at the rear edge of the base is provided with a power switch.

Due to the adoption of the above solution: the external hard disk box has good shockproof and dustproof effects.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is an exploded view of the first embodiment of the utility model;

Fig. 2 is an exploded view of the second embodiment of the utility model;

Fig. 3 is a partial combination diagram of Fig. 2 of the second embodiment of the present invention;

Figure 4 is a schematic diagram of a conventional hard disk;

Fig. 5 is a sectional view of a conventional external hard disk box.

As shown in Figure 1, the first embodiment is mainly composed of a top cover 1, a hard disk 2 and a base 3, wherein the connection port 21 on the rear edge of the hard disk 2 and the connection port 31 on the rear edge of the base 3 and the power connection port 32 are respectively connected with a flexible circuit board 33 and a power cord 34 to conduct, and then sealed with an upper cover 1 to form a portable independent entity.

Fixing blocks 4 are installed on the periphery of the hard disk 2 in the box body, and several soft pads 5 are respectively provided on the upper and lower sides of the hard disk 2 and around the outer sides of the fixing block 4, wherein the locking holes on the side walls of the hard disk 2 are used. 22. Lock the "L"-shaped fixed block 4 on it, and the soft pad 5 includes a lower pad 51, a frame pad 52, an upper pad 53, etc., and the lower pad 51 is arranged between the hard disk 2 and the Between the base 3 , the hollow groove 521 of the frame protection piece 52 can just frame around the fixed block 4 outside the hard disk drive, and the above protection piece 53 is lined between the hard disk 2 and the upper cover 1 .

Use the fixed block 4 and the frame guard 52 to protect and absorb the lateral shock force around the hard disk 2, and the upper guard 53 and the lower guard 51 laid on the upper and lower sides of the hard disk 2 can also absorb the shock of the hard disk 2. Vibration forces in the up and down directions are used to reduce the degree to which the hard disk 2 is affected by the vibration. In addition, the hard disk 2 is protected and sealed by the upper cover 1 and the base 3 to prevent the intrusion of dust.

In the soft protective pad 5, the upper protective sheet 53, the lower protective sheet 51 and the frame protective sheet 52 all have the characteristics of shock absorption, therefore, when the external hard disk box is subjected to vibration, the soft protective pad and the function of reducing the impact of the hard disk 2 The function of vibration, in addition, the space of the hard disk 2 can be adjusted by the fixed block 4 outside the hard disk 2, reducing the degree of shaking that the hard disk 2 can produce, and the hard disk 2 is more firmly placed on the upper cover 1 and the base within 3.

As shown in Figures 2 and 3, the soft protective pad 5 of the second embodiment can be formed by arranging several columns, so that it can be evenly fixed (attached) on the upper and lower sides of the hard disk 2 and the outside of the fixing block 4 around to achieve the desired effect.

In addition, as shown in Figures 1 and 2, the utility model uses the flexible circuit board 33 and the power cord 34 as the electrical connection between the hard disk 2 and the base 3, because the softness and flexibility of the flexible circuit board and the electric wire are better Therefore, when the hard disk 2 is shaken or shaken, the structure of the flexible circuit board has little influence on the displacement of the relative distance caused by the vibration, so that the signal can be continuously and normally transmitted to the memory or the calculator without Intermittent, and the power connection port 32 at the rear edge of the base 3 is a coaxial power socket, and a power switch 35 can be provided on one side, so that the hard disk of the present utility model can use a power supply other than a computer as A source of operating electricity.
