Abstract

The present invention relates to a shock absorber that makes a computer hard disk durable against vibration and shock, and uses a restoring force against compression and deformation of silicon to fix a minimum fixed point around four vertices of a hard disk cover frame. It can be adapted to the shock and vibration in the multi-axis direction. In addition, the front, rear, front, rear, right and left corners of the hard disk are coated with a certain thickness of silicon to absorb shocks from all directions.

Description

Hard disk impact mitigation device using elasticity and resilience of silicon. {Omitted}

The present invention is a shock absorbing device for increasing the durability against shock and vibration that can be applied when using a computer hard disk as a vehicle or a portable storage device. Generally, flash memory is widely used as a portable storage device, but its capacity is small, and thus there are limitations on various uses. In order to enable the use of hard disks that are less expensive than their capacity as a large-capacity removable storage device, silicon, which has excellent characteristics in heat resistance, cold resistance, restorability, and compression permanent reduction, is used. Structural molding (1) of the form to reduce the impact.

It is convenient and economical to use a portable hard disk to move large amounts of data such as music files (MP3) and video files (Mpeg4, Divx), which are various multimedia data files, but it is weak to vibration and shock due to the characteristics of physical media. There is this. For the same reason, the purpose is to protect the data and to increase the durability of the entire system by applying earthquake resistance to a vehicle computer or a mobile hard disk.

Conventionally, only plastic or aluminum housing is applied to a general hard disk to apply a partial shock mitigation effect, or use a plate spring between an external housing and a main body of a hard disk, or a member such as a rubber ring or a one spring that wraps around a bolt to be fastened. Used.

However, the prior art can be effective only in a limited impact direction and may cause noise generation depending on the cushioning member used.

The present invention has been invented to solve the problems of the prior art, using a silicone polymer having excellent resilience to compression and deformation in order to effectively dissipate energy and absorb the physical impact of the hard disk, and a specific structured molding (1) The first purpose is to enable effective effects on vibration and shock. In addition, there is no significant change in elasticity from low temperature to high temperature (-60 ° C. to 250) due to the nature of the bonding energy of silicone rubber, and it has an electrical property with excellent insulation property and also has an insulator effect having heat resistance and cold resistance. Purpose. In addition, silicone rubber does not burn easily due to its molecular structure of hydrocarbon content is lower than that of general mechanical rubber, and because it does not contain halogen elements, it has a flame retardant property that does not generate toxic gases during combustion. It has the right characteristics when related.

2 is a schematic block diagram of a silicone molding of the present invention. As shown in FIG. 2, the four corners at the top and the four corners 2 at the bottom are fixed to the inner wall edges of the housing, respectively. Between each corner contact and the contact portion is formed a U-shaped valley (4) with a gradual change in curvature to achieve a continuous buffering effect according to the impact strength.

As described above, the present invention is made of silicon, which has excellent properties of flame resistance, heat resistance, and cold resistance, so that it does not corrode other materials because it has excellent insulation properties and chemically inert materials. Maintain elasticity of hard disk by maintaining original elasticity even in bad condition from -60 ℃ to 250 ℃. In addition, the upper four corners and the lower four corners are fixed to the inner wall edges of the housing, respectively, so that they have a small number of fixed support points 2, so that they can be adapted to impacts in various directions. U-shaped valleys 4 having a gradual curvature change are formed between the fixed support points 2, thereby providing a flexible buffering effect according to impact strength.
