A structure capable of reducing the mass and volume of an anti-seismic mobile hard disk

technical field

The invention relates to a structure capable of reducing the mass and volume of an anti-seismic mobile hard disk, belonging to the field of mechanical structure design.

Background technique

Mobile hard disk is a small, precise, fast, and portable memory, which is widely used because of its small size, light weight, simple use, and convenient portability. At present, with the rapid progress of my country's IT industry and precision instrumentation industry, the sales volume of mobile hard disks in China's domestic market has accounted for about 40% of the total global sales volume, and it is increasing year by year. For the multi-track hard disk of the mobile storage, the data will not be able to be read and restored after a slight impact, and the value of the used mobile storage will be much higher than the price of the new product of the same item. Most of the mobile hard disks currently on the market have almost no shock resistance and shock absorption functions. Figure 1 shows a mobile hard disk without shock resistance. It mainly consists of a mobile hard disk cover 1, screws 2, pads 3, and a mobile hard disk body 4. The mobile hard disk lower body 5 is formed, and the damping function of the spacer 3 is extremely weak. For a small number of mobile hard disks with anti-seismic performance as shown in Figure 2, it consists of an upper body 6 with a shock-absorbing mobile hard disk, a mobile hard disk shock absorber 7, and a lower body 8 with a shock-absorbing mobile hard disk. The shock device, the shock absorber 7 upper and lower shells 10, 11 are fixedly connected (welding, thermal bonding, bonding, threaded connection, etc.) are non-movable parts, and the push-type compression disc 9 is a movable part. When assembling, pass through the reserved hole of the upper shell 10, the part outside the upper shell 10 is a push rod, which plays the role of bearing external force, and the part inside the upper shell 10 is a compression plate, which can evenly bear the external force Distribute the action applied to the elastomer 11. Because of its shock absorbing device, the volume and quality of the mobile hard disk increase, which is not easy to carry, and increases the burden of shock absorption, thereby reducing the shock absorption efficiency and affecting the popularization and use of shock-resistant mobile hard disks.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings of the above-mentioned anti-seismic mobile hard disk, and propose a structure that can reduce the quality and volume of the anti-seismic mobile hard disk. While having anti-seismic function, its mass and volume can be reduced, thereby increasing the stability of shock absorption and improving its shock absorption effect.

In order to achieve the above object, the technical solution adopted in the present invention is: mainly include the mobile hard disk box upper cover 15, the mobile hard disk box lower body 14, the hard disk body 4, the upper cover 15 and the lower body 14 are fixedly connected, and the hard disk body 4 is arranged around the two In the inner space formed, a shock absorber 7 is arranged between the hard disk body 4 and the upper cover 15 and the hard disk body 4 and the lower body 14; the shock absorber 7 includes an upper casing 10 and a lower casing 11, and the upper casing 10 and the lower casing The shells 11 are fixedly connected, and an elastic body 12 is arranged in the cavity surrounded by the upper shell 10 and the lower shell 11. A through hole 20 is left on the top of the upper shell 10, and an inverted " T"-shaped push-type compression disk 9, the compression disk 18 of the push-type compression disk 9 is located in the cavity provided with the elastic body 12, and the push rod 19 of the push-type compression disk 9 passes through the through hole 20 at the top of the upper shell 10 and The hard disk body 4 is fixedly connected, and the lower shell 11 is fixedly connected with the upper cover 15 or the lower body 14 . On the loam cake 15 that is fixed with shock absorber 7 and lower body 14, the position corresponding with shock absorber 7 is all provided with protruding shell 17, and its size, shape and shock absorber 7 adapt, and shock absorber 7 Set in the raised shell 17.

Existing mobile hard disk increases the size of mobile hard disk because of packing into several damping devices 7, and then makes the overall volume of mobile hard disk increase, now the mobile hard disk box is made with some protruding shells 17, and the Shock absorbing device 7 is put into raised shell 17, can greatly reduce the overall size of moving hard like this, dwindles the quality and the volume of moving hard disk, thereby makes moving hard disk easy to carry. And the damping device 7 is fixed in the raised shell 17, which improves the overall rigidity of the mobile hard disk, thereby increasing the stability of the damping and improving its damping effect.

Detailed ways

For the specific implementation manner of the present invention, refer to FIGS. 4-10 .

This embodiment designs a mobile hard disk box structure, and the mobile hard disk box is designed into two parts: the lower body 14 of the mobile hard disk box and the upper cover 15 of the mobile hard disk box. The lower body 14 of the mobile hard disk box is shown in Figure 4, Figure 5, and Figure 6. , shown in Fig. 7, it is a square structural shell as a whole, and seven raised shells 17 are made altogether on five side surfaces of wherein the lower body 14 of the mobile hard disk box simultaneously, and its thickness is consistent with the overall shell thickness of the lower body 15 of the mobile hard disk box , the size of the raised shell 17 is just enough to put the shock absorber 7 into it, and four threaded holes 13 are drilled at the four corners of the lower body 14 of the mobile hard disk box. The upper cover 15 of the mobile hard disk box is shown in Figure 7 and Figure 8 , shown in Fig. 9, it is also a square structural shell, also makes two raised shells 17 on its uppermost surface, its size, thickness dimension are the same as seven raised shells 17 on the lower body 14 of the mobile hard disk box, and in Four stepped through holes 16 are drilled at the four corners of the upper cover of the mobile hard disk box, and four screws can be used to pass through the stepped through holes 16 at the four corners of the upper cover of the mobile hard disk box 15 and the threaded holes at the four corners of the lower body of the mobile hard disk box 13 Connect the two together to form a new type of mobile hard disk box, and then put the shock absorbing device 7 and hard disk body 4 of the mobile hard disk into it to form a new type of anti-vibration mobile hard disk.

When the mobile hard disk is assembled, the shock absorber 7 is placed in the raised square shell of the lower body 14 of the mobile hard disk box and the upper cover 15 of the mobile hard disk box, and then the disc body 4 is put into the lower body 14 of the mobile hard disk box and connected with it. The damping device 7 of the mobile hard disk box is in contact with each other, so that the mobile hard disk body 4 is in a suspended state, and then four screws are screwed into the threaded holes around the lower body 14 of the mobile hard disk box through the stepped through holes 16 on the 15 sides of the mobile hard disk box upper cover 13, so that the two are connected together.

Shock-absorbing device 7 is little excessively fit between the raised shell 17 of mobile hard disk case lower body 14 and mobile hard-disk case loam cake 15, can guarantee the stability of shock-absorbing device in the box.

The lower body 14 of the mobile hard disk box and the upper cover 15 of the mobile hard disk box can be processed by thermal injection molding, and the materials are ABS plastics. Except that the elastic body 12 adopts rubber or polyurethane, all the other adopt ABS plastics.
