Description

Technical Field

[0001] The present invention relates to the technical field of vein recognition for a computer host, in particular to a safety control device for vein recognition for a computer host. Background Art

[0002] With the rapid development of social economy, users have an increasing demand for individual identity recognition. As an effective way of identity recognition, fingerprint recognition has been applied in more and more fields. With the widespread application of fingerprint recognition technology, the incidents of forged and counterfeit fingerprints occur from time to time.

[0003] The emergence of fingerprint imitation technology has made the security of personal identity recognition increasingly valued by the public. Finger vein recognition devices have been born on this basis. Finger vein recognition, as a fast, simple, accurate and efficient personal identity recognition technology, has been increasingly recognized by the public. Existing finger vein recognition devices usually place the user's finger flat on an infrared light source and cooperate with an auxiliary finger positioning structure to obtain a relatively accurate finger vein image.

[0004] The prior art has the following defects or problems:

[0005] 1. When the existing vein recognition device for a computer host is used, the focal length of the camera for collecting vein infrared images cannot be adjusted, so the user's stored image and the captured image do not match, resulting in the problem of being unable to be recognized;

[0006] 2. The existing vein recognition device for computer host has a fixed position inside. When the installation angle of the vein recognition device inside the computer host is tilted, the user needs to turn his finger for matching, which is not a good experience.

[0007] 3. The existing vein recognition device for computer host is a precision instrument, which is laborious to disassemble, resulting in a waste of time and manpower for subsequent maintenance. Summary of the invention

[0008] The purpose of the present invention is to provide a safety control device for vein recognition of a computer host in view of the deficiencies of the prior art, so as to solve the problems raised in the background technology.

Through the coordinated use of the linkage structure and the focusing device, the identification focal length can be adjusted according to the insertion degree of the user's finger to improve the recognition probability, and with the coordinated use of the top cover sliding device and the built-in sub-shell structure, the identification surface of the vein recognition can be kept level with the pad of the user's finger, which is convenient for use.

[0010] As a preferred technical solution of the present invention, the upper cover sliding device includes an upper cover, a slide groove and an infrared filter lamp. The number of the slide grooves is two groups, the number of the infrared filter lamps is several, and the infrared filter lamps are distributed in an arc around the upper cover, playing the role of sealing the identification device and providing a sliding track to adjust the angle of the identification device.

[0011] As a preferred technical solution of the present invention, the built-in sub-shell structure also includes a first baffle, a second baffle, a first socket, a second socket and a slider, the number of the sliders matches the slide groove, and the built-in sub-shell structure rotates in an arc around the upper cover sliding device through the slider and the slide groove, and the maximum rotation angle exceeds 90°, thereby carrying the internal components of the identification device and adjusting the identification angle of the identification device.

[0012] As a preferred technical solution of the present invention, the focusing device includes a driven gear, a first screw rod and a camera. The angle of the camera is fixed and the upper and lower positions are adjustable. A spiral groove is opened inside the camera. The driven gear is fixedly connected to the first screw rod. The first screw rod rotates around the identification seat to adjust the focal length of the camera, facilitate imaging, and improve the recognition probability.

[0013] As a preferred technical solution of the present invention, the linkage structure includes a finger sleeve, a sensing switch, a second spiral rod, a driving gear, a spiral tube, a first fixing ring, a first bearing and a first fixing hole. The sensing switch is electrically connected to the main processing module, the first fixing ring is fixedly connected to the second baffle through the first fixing hole, the inner diameter of the spiral tube matches the outer diameter of the second spiral rod, and the driving gear and the driven gear are meshed with each other, so as to transmit external power to drive the camera to move up and down.

[0014] As a preferred technical solution of the present invention, the flap structure includes a side baffle, an insert rod, a second fixing ring and a second bearing. The side baffles are in two groups. The second fixing ring is fixedly connected to the main shell. The insert rod rotates through the second bearing to act as a sealing identification device, which facilitates the installation and disassembly of the identification device.

[0015] As a preferred technical solution of the present invention, a fixing device is provided on the side of the insertion rod away from the second fixing ring, and the fixing device includes a screw cap and a screw rod. A rubber pad is attached to the side of the screw cap close to the screw rod. The outer diameter of the screw rod matches the inner diameter of the insertion rod, thereby playing a role in fixing the flap structure.

[0016] As a preferred technical solution of the present invention, the power supply, main processing module, storage module and infrared image comparison module are connected in series, the infrared filter lamp and the camera are electrically connected to the power supply and the two are connected in parallel, and the signal output port is electrically connected to the computer host and the main processing module, which plays a role in user finger vein recognition to protect the computer host.

[0017] Compared with the prior art, the present invention provides a safety control device for vein recognition of a computer host, which has the following beneficial effects:

[0018] 1. A safety control device for vein recognition for a computer host is provided with a focusing device and a linkage structure. When in use, the user inserts a finger into the inside of the finger sleeve and pushes the finger sleeve to move inward. At this time, the induction switch transmits a signal to the main processing module, and turns on the camera, the infrared image comparison module and the infrared filter lamp. The second screw rod moves to one side under the push of the finger sleeve and drives the driving gear to rotate. Since the driving gear and the driven gear are meshed with each other, the driven gear is driven to rotate, and then the camera is moved up and down through the first screw rod to adjust the focal length of the finger vein imaging, thereby reducing the difficulty of recognition;

[0019] 2. The safety control device for vein recognition of a computer host is provided with a built-in sub-shell structure and an upper cover sliding device. When in use, the recognition device is installed inside the computer host, and the output end of the recognition device is electrically connected to the input end of the computer host. When the recognition device is installed at a certain angle, under the gravity of the built-in sub-shell structure, the recognition seat rotates around the upper cover through the slider and the slide groove, so that the finger sleeve is always kept horizontal to the ground, which is convenient for users to use and improves the comfort of using the vein recognition device.

[0020] 3. This safety control device for vein identification of a computer host is provided with a flap structure and a fixing device. When in use, when the identification device is disassembled, the rotary cover is rotated to make the screw gradually screw out of the insertion rod. At this time, the side baffle can be rotated around the second fixing ring through the insertion rod and the second bearing to open the identification device. Similarly, when the identification device is installed, the rotary cover can be rotated in the opposite direction to make the screw screw into the inside of the insertion rod. Because the surface of the rotary cover has a rubber pad, the friction with the main shell can be increased while fixing the side baffle to prevent the fixing device from falling off, thereby reducing the difficulty of later maintenance of the identification device and saving manpower and time.

[0041] The working principle and use process of the present invention: a computer host uses a vein recognition security control device, such as Fig.10 As shown in A, when in use, the identification device is installed inside the computer host 13, and the signal output port 12 of the identification device is electrically connected to the input end of the computer host 13.
