Problems solved by technology

However, due to the small size of the U disk, it will be accidentally dropped on the ground, which will damage the U disk, affect the appearance, and may even cause data loss, causing great inconvenience to work and study
At present, in the prior art, most of the anti-vibration measures adopted by the U disk are to set anti-vibration strips on the U disk to achieve the purpose of anti-vibration, but the anti-vibration performance is poor, and the anti-vibration strip has a complicated structure and high cost

Embodiment 1

[0011] Embodiment 1, a kind of U disk, comprises USB interface 1, circuit board 2, housing 3, and circuit board 2 is arranged on the inside of housing 3, and one end of housing 3 is provided with USB interface 1, and described housing 3 is provided with by the inside of housing. layer 4 and an elastic shell outer layer 5, the outer shell layer 5 is provided with a groove 6, which divides the outer shell layer 5 into pieces, the bottom of the groove 6 is sealed and connected with the inner shell layer 4, and is connected with the inner shell layer 4 forming a shock-absorbing cavity 7, and an elastic element is arranged in the shock-absorbing cavity 7 to increase the elasticity of the shell outer layer 5, so that the shock-proof effect is better. Vibration can be effectively reduced, and the shell outer layer 5 is divided into blocks by grooves 6, so that the overall rigidity is reduced and the elasticity is increased, and even if a part is bumped, the overall force will not be l...

Embodiment 2

[0012] Embodiment 2 differs from Embodiment 1 in that: the inner layer of the casing 3 can be provided with grooves 6 corresponding to the outer layer of the casing, thereby increasing the volume of the shock-absorbing cavity and improving the shock-proof effect. A weighting block 8 is arranged at the bottom of the U disk body. When the U disk slides down, it can only tilt and is not easy to fall due to the transfer of the center of gravity, which can prevent the U disk from being broken and prolong the service life of the U disk.

Abstract

The objective of the invention is to provide a U-disk shockproof structure which is simple in structure, low in cost and long in the service life. The U-disk shockproof structure comprises a circuit board and a shell. The circuit board is arranged in the internal part of the shell. One end of the shell is provided with a USB interface. The shell is composed of a shell internal layer and a shell external layer with elasticity. The shell external layer is provided with grooves so that the shell external layer is divided into blocks. The shell internal layer is provided with the grooves which are corresponding to those of the shell external layer so that shock-absorbing chambers are formed by the grooves and the shell internal layer. The shock-absorbing chambers are internally provided with elastic elements. The shell internal layer is the layer with elasticity so that shock can be effectively reduced. The U-disk shockproof structure is mainly applied to memory equipment in the field of computers.

Description

technical field [0001] The invention relates to a U disk, in particular to a shockproof structure of the U disk. Background technique [0002] With the advancement of science and technology, computers are often used in work and study, and the electronic data formed by computers is often updated, moved or backed up, so storage devices are essential, especially U disks, which are frequently used and very convenient , so people often carry USB flash drives on their bodies. However, due to the small size of the USB flash drive, it will be accidentally dropped on the ground, which will damage the USB flash drive, affect the appearance, and even cause data loss, causing great inconvenience to work and study. At present, in the prior art, most of the anti-vibration measures adopted by the U disk are to set anti-vibration strips on the U disk to achieve the purpose of anti-vibration, but the anti-vibration performance is poor, and the anti-vibration strip has a complicated structur...
