Embodiment 1

[0027] Such as Figure 1-4 As shown, an anti-drop and anti-theft USB flash drive includes a shell 4, an internal circuit 6 and a motor, and the internal circuit 6 includes a fingerprint recognition circuit and a motor drive circuit connected to the motor; the shell 4 is provided with a fingerprint recognition area 8 , and connected with the fingerprint recognition circuit; one end of the housing 4 is provided with a baffle and a pull rod 9, one end of the pull rod 9 is connected with the baffle, and the other end is connected with the motor, and the inside of the housing 4 is composed of A carbon fiber layer 3 , a polyethylene fiber layer 2 and a sponge layer 1 are sequentially arranged from outside to inside, and a spring 7 is arranged in the sponge layer 1 ; the internal circuit 6 is adhered to the sponge layer 1 . Fingerprint recognition successfully starts the motor drive circuit, and the drive bezel is lowered to extend the USB, and it can be used after connecting with th...

Embodiment 2

[0029] Such as figure 1 As shown, on the basis of Embodiment 1, a destroying block 5 is provided on the baffle, and the destroying block 5 is located in the gap of the USB interface when the baffle is closed. If it is forcibly opened, the destroying block 5 will It will damage the USB interface, so that the U disk cannot be connected to the computer, which is very safe.

Embodiment 3

[0031] Such as image 3 As shown, on the basis of Embodiment 1, the fingerprint identification circuit includes a fingerprint identification chip GF516M and a peripheral circuit, and the peripheral circuit includes a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, The sixth capacitor, the seventh capacitor, the eighth capacitor and the first resistor.

Abstract

The invention discloses an anti-falling and anti-theft USB flash disk. The USB flash disk is characterized by comprising a shell, an internal circuit and a motor. The internal circuit comprises a fingerprint identification circuit and a motor driving circuit connected with the motor. The shell is provided with a fingerprint identification area, and is connected with the fingerprint identificationcircuit. A baffle plate and a pull rod are arranged at one end of the shell. One end of the pull rod is connected with the baffle plate. The other end of the pull rod is connected with the motor. A carbon fiber layer, a polyethylene fiber layer and a sponge layer are sequentially arranged in the shell from outside to inside. A spring is arranged in the sponge layer. The internal circuit is adheredto the sponge layer. The anti-falling and anti-theft USB flash disk is low in cost, simple in structure and good in anti-collision effect. An additionally arranged suction layer is good in elasticity, high in strength and not easy to damage. A destroy block is arranged on the baffle plate. When no motor driving force is provided for opening the baffle plate, a USB interface can be damaged when being forcibly pried open. Therefore, data in the USB flash disk cannot be read so as to achieve the purpose of confidentiality.

Description

technical field [0001] The invention belongs to the field of U disks, and in particular relates to an anti-drop and anti-theft U disk. Background technique [0002] U-disk, the full name of USB flash drive, the English name "USB flash disk". It is a miniature high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to a computer through a USB interface to achieve plug-and-play. The name of the U disk originated from a new type of storage device produced by Netac Technology, named "U disk", which is connected with a USB interface. After the U disk is connected to the USB interface of the computer, the data of the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technologies produced later, they can no longer be called "USB disks", but are renamed "U disks" with homophonic sounds. Later, the name U disk was widely known because of its simplicity and ease of r...
