DETAILED DESCRIPTION

[0029] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0030] The embodiments of the present application will be described below in connection with the drawings. Figures 1 to 6 An extension type fingerprint recognizer for a smart lock is described.

[0031] In one embodiment, an extension type fingerprint recognizer for a smart lock includes a recognizer shell 100, an extension type recognizer, an adjusting piece 300, and a limiting piece 400. The recognizer shell 100 has a first mounting cavity 110 formed inside and an opening 120 formed on the surface. The extension type recognizer 200 is rotatably installed at the opening 120. The extension type recognizer 200 includes an arc surface 241 and a mounting surface 242. A recognizer body is installed on the mounting surface 242. The mounting surface 242 and the arc surface 241 are always located in the first mounting cavity 110. The adjusting piece 300 is installed in the first mounting cavity 110. One end of the adjusting piece 300 extends out of the recognizer shell 100, and the other end of the adjusting piece 300 abuts against the extension type recognizer 200. The limiting piece 400 is installed in the first mounting cavity 110 and contacts the one end of the extension type recognizer 200 abutting against the adjusting piece 300, for limiting the one end of the adjusting piece 300.

[0032] Specifically, one of the curved surface 241 and the mounting surface 242 of the protruding identifier 200 is always located in the first mounting cavity 110. When not in use, the mounting surface 242 is located in the first mounting cavity 110, and the identifier body is mounted on the mounting surface 242. The curved surface 241 closes the opening 120. When it is needed, the protruding identifier 200 is moved so that the curved surface 241 enters the first mounting cavity 110. At this time, the mounting surface 242 faces the outside of the identifier housing 100, and the user can perform fingerprint recognition. At the same time, one end of the adjusting member 300 will abut against the curved surface 241 and maintain stability between the curved surface 241. When use is completed, the adjusting member 300 can be moved to eliminate the balance of the abutting force between the end of the adjusting member 300 and the curved surface 241, so that the protruding identifier 200 rotates back to its original position.

[0033] The above-mentioned smart lock uses an extendable fingerprint identifier. One of the curved surface 241 and the mounting surface 242 of the extendable identifier 200 is always located in the first mounting cavity 110. When not in use, the mounting surface 242 is located in the first mounting cavity 110, and the identifier body is mounted on the mounting surface 242. The curved surface 241 closes the opening 120. When it needs to be used, the extendable identifier 200 is moved to make the curved surface 241 enter the first mounting cavity 110. At this time, the mounting surface 242 faces the outside of the identifier housing 100, and the user can perform fingerprint recognition. At the same time, one end of the adjusting member 300 will abut against the curved surface 241 and maintain stability between the curved surface 241. When use is completed, the adjusting member 300 can be moved to eliminate the balance of the abutting force between the end of the adjusting member 300 and the curved surface 241, so that the extendable identifier 200 rotates back to its original position. This setting prevents the device from being exposed to the outside for a long time and being contaminated by various dust or oil stains, which may affect subsequent use, and also avoids the risk of collision with external objects.

[0034] In one embodiment, first mounting holes 150 are provided on two opposite inner walls of the identifier housing 100, and the extendable identifier 200 includes a rotating shaft 210, an identifier mounting seat 220 and a torsion spring 250; the two ends of the rotating shaft 210 are movably mounted in the two first mounting holes 150, and the identifier mounting seat 220 is sleeved on the rotating shaft 210, one side of the identifier mounting seat 220 is an arcuate surface 241, and the other side is a mounting surface 242, and the torsion spring 250 is sleeved on the rotating shaft 210, and the two ends of the torsion spring 250 are respectively connected to the identifier mounting seat 220 and the inner wall of the identifier housing 100.

[0035] Specifically, two side plates 140 are arranged at the opening 120, and the end face of the side plate 140 is arranged in an arc structure. When the mounting surface 242 is located in the first mounting cavity 110, the arc surface 241 is located in the same curved surface range as the end face of the side plate 140. A limiting groove 230 is formed on the arc surface 241 around the rotating shaft 210, and a limiting block 130 is arranged at the opening 120, and the limiting block 130 is movably clamped in the limiting groove 230.

[0036] In one embodiment, a second mounting hole 160 is formed on the front face of the identifier shell 100, and the adjusting member 300 comprises an adjusting rod 310 and a plug 350. One end of the adjusting rod 310 is inserted into the second mounting hole 160, the other end of the adjusting rod 310 is bent downward and connected to the plug 350, and the plug 350 abuts against the limiting groove 230.

[0037] Specifically, the adjusting member 300 further comprises a first limiting plate 320, a second limiting plate 330 and a first spring 340. The first limiting plate 320 and the second limiting plate 330 are located inside the first mounting cavity 110 and outside the identifier shell 100 respectively, and both the first limiting plate 320 and the second limiting plate 330 are connected to the adjusting rod 310. The first spring 340 is sleeved on the adjusting rod 310, and both ends of the first spring 340 are connected to the first limiting plate 320 and the inner wall of the identifier shell 100 respectively.

[0038] In the normal state, the second limiting plate 330 has a certain gap with the identifier shell 100, and the adjusting rod 310 has elasticity. When the second limiting plate 330 is pressed, the adjusting rod 310 moves towards the inside of the first mounting cavity 110, and the plug 350 moves away from the limiting groove 230.

[0039] In one embodiment, a second mounting cavity 170 is formed on the back face of the identifier shell 100, and a third mounting hole 180 is formed on the surface of the second mounting cavity 170. The limiting member 400 comprises a movable block 410, a fixed rod 420 and a third limiting plate 440. The movable block 410 is movably clamped in the second mounting cavity 170, the fixed rod 420 is movably inserted into the third mounting hole 180, one end of the fixed rod 420 is fixed in a second clamping groove 412 formed on the back face of the movable block 410, the other end of the fixed rod 420 is fixed with the third limiting plate 440, and a first clamping groove 411 is formed on the front face of the movable block 410. The plug 350 is clamped in the first clamping groove 411.

[0040] Specifically, a second spring 430 is sleeved on the fixed rod 420, and both ends of the second spring 430 are connected to the bottom surface of the second clamping groove 412 and the bottom surface of the second mounting cavity 170 respectively.

[0041] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0042] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
