[0001] The present invention relates to the technical field of computer fingerprint recognition, and specifically to a computer fingerprint recognition button. Background Art

[0002] At present, the fingerprint recognition button module used on electronic computers, especially laptops, is a capacitive fingerprint recognition module. A fingerprint sensor encapsulated by LGA is provided with a cover plate or a coating to obtain fingerprint information, and then the fingerprint information is transmitted to the computer for processing. In order to make the fingerprint recognition button module have a light-emitting indication effect, a common method is to add a light-emitting component in the fingerprint recognition button module, and cooperate with a corresponding transparent structure to make the fingerprint recognition button module have a light-emitting indication effect.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as a limitation of the present invention.

[0031] The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0032] A computer fingerprint recognition button, as Figures 1 to 7 shown, includes a fingerprint recognition mechanism 1. The fingerprint recognition mechanism 1 includes a fixed seat 101. Two groups of sliding frames 102 are slidably sleeved on the inner wall of the fixed seat 101. A group of fingerprint recognition modules 103 are respectively fixedly connected to the inner walls of the two groups of sliding frames 102. A group of convex plates 104 are respectively fixedly connected to the bottom ends of each group of fingerprint recognition modules 103. A plurality of first contacts 105 are fixedly connected to the bottom end of the convex plate 104. Two groups of connecting plates 107 are fixedly connected to the inner wall of the fixed seat 101. A group of convex blocks 108 are respectively fixedly connected to the top ends of each group of connecting plates 107. A plurality of second contacts 109 are respectively fixedly connected to the top ends of each group of convex blocks 108. A plurality of spring pieces 106 are fixedly connected to the inside of the fixed seat 101. The top ends of the plurality of spring pieces 106 are respectively fixedly connected to the bottom ends of the two groups of fingerprint recognition modules 103. A plurality of mounting blocks are arranged at the bottom end position of the outer wall of the fixed seat 101, and fixing holes are penetrated through the top ends of the mounting blocks.

[0033] When using the fingerprint recognition button, by pressing two groups of fingerprint recognition modules with a finger, the two groups of fingerprint recognition modules simultaneously recognize the fingerprint on the finger, so that the recognition area of the finger is larger. During the process of pressing the fingerprint recognition module, the spring piece 106 is compressed, causing the convex plate 104 at the bottom of the fingerprint recognition module 103 to move downward, so that the first contact 105 contacts the second contact 109. Thus, the scanned fingerprint information is transmitted to the flexible cable 211 through the wire 203. After the recognition is completed, the fingerprint recognition module 103 is released, and the spring piece 106 rebounds to push the fingerprint recognition module 103 to slide upward and reset. When accidentally touching the fingerprint recognition module 103, since the first contact 105 and the second contact 109 are not in contact, the situation of accidental touch of the fingerprint recognition module 103 is avoided.

[0034] Please refer specifically to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 ., two sets of connecting mechanisms 2 are fixedly connected to the bottom end of the fixing seat 101. Each set of connecting mechanisms 2 respectively includes a set of sleeves 202. A set of side plates 201 are respectively fixedly sleeved at both ends of the inner wall of the sleeve 202. Multiple wires 203 are respectively fixedly connected to the side walls of each set of side plates 201. The ends of the multiple wires 203 are respectively electrically connected to multiple second contacts 109. Multiple conductive rings 204 located inside the sleeve 202 are fixedly connected to the side walls of the side plates 201. The multiple conductive rings 204 are respectively electrically connected to a set of wires 203. A set of turntables 205 are respectively rotatably connected to the side walls of each set of side plates 201. A spring 210 is arranged at the connection between the turntable 205 and the side plate 201. Multiple copper tubes 206 are fixedly connected to the inner wall of the turntable 205. A set of thimbles 207 are respectively slidably sleeved inside each set of copper tubes 206. The ends of each set of thimbles 207 respectively abut against the side walls of a set of conductive rings 204. A reel 209 is fixedly connected between the two turntables 205. A flexible cable 211 is wound around the outer wall of the reel 209. The copper wires inside the flexible cable 211 are respectively electrically connected to multiple copper tubes 206. A connection head 212 is fixedly connected to the end of the flexible cable 211. Multiple conductive sheets 213 are fixedly connected to the bottom end of the connection head 212. The multiple conductive sheets 213 are electrically connected to the copper wires inside the flexible cable 211. A pressure spring 208 is fixedly connected to the end of the thimble 207 located inside the copper tube 206. The end of the pressure spring 208 is fixedly connected to the inner wall of the copper tube 206.

[0035] By pulling the connector 212, the connector 212 pulls out the wire from the sleeve 202, so that the connector 212 can be inserted into the interface on the main board. During the process of pulling out the flexible cable 211, the reel 209 rotates, causing the reel 209 to drive the turntable 205 to rotate. During the rotation of the turntable 205, the clockwork spring 210 is twisted. During the rotation of the turntable 205, the copper tube 206 is driven to rotate, and the copper tube 206 drives the thimble 207 to rotate, causing the thimble 207 to slide on the outer wall of the conductive ring 204. During the rotation of the turntable 205, the thimble 207 is always electrically connected to the conductive sheet 213. Therefore, the wire 203 and the flexible cable 211 are always kept electrically connected. The resilience of the compression spring 208 is applied to the end of the thimble 207, so that the thimble 207 fits tightly with the conductive ring 204. The resilience of the clockwork spring 210 enables the reel 209 to wind up the flexible cable 211, avoiding the long flexible cable 211 from scattering inside the computer and making the inside of the computer cleaner.

[0036] When in use, by pressing the fingerprint recognition module 103, the first contact 105 and the second contact 109 come into contact, so that the fingerprint information recognized on the fingerprint recognition module 103 is transmitted to the computer. When accidentally touching the fingerprint recognition module 103, since the first contact 105 and the second contact 109 are not connected together, the phenomenon of accidental touch during use is avoided. The parts not involved in this device are the same as or can be implemented by the prior art.

[0037] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations to the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
