Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The technical scheme disclosed by each embodiment of the utility model is described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 3, a fingerprint lock is disclosed in an embodiment of the present application. The disclosed fingerprint lock includes a door handle 100, a clutch 200, a spacer 300, a lock cylinder 400, a fingerprint acquisition module 500, and a fingerprint harness 600.

The door handle 100 is a member of the fingerprint lock for a user to operate to open and close a door, and is also a mounting base of the fingerprint acquisition module 500. The fingerprint collection module 500 is mounted on the door handle 100, and thus can collect fingerprint information of a user while the user holds the door handle 100.

The fingerprint collection module 500 is used for collecting the module of user's fingerprint to realize the identity recognition function of fingerprint tool to lock. In this application embodiment, fingerprint collection module 500 can be optical fingerprint collection module, also can be ultrasonic fingerprint collection module, and this application embodiment does not restrict the specific kind of fingerprint collection module 500.

The clutch 200 is a member for realizing a clutch function in the fingerprint lock, the clutch 200 is connected with the door handle 100, and the clutch 200 can be matched with the lock cylinder 400. Specifically, clutch 200 may be fixedly coupled to door handle 100 via fastener 830.

In the embodiment of the present application, the clutch 200 is matched with the lock cylinder 400, and the specific matching is as follows: the clutch 200 has a disengaged state and an engaged state. When the clutch 200 is in the disengaged state, the door handle 100 and the lock cylinder 400 are separated, so that the door handle 100 cannot be driven, and the user can not drive the lock cylinder 400 to rotate when rotating the door handle 100, so that the lock cylinder 400 is kept in the locked state, and the door body is locked. When the clutch 200 is in the engaged state, the door handle 100 and the lock cylinder 400 are in transmission connection through the clutch 200, and at the moment, a user rotates the door handle 100 to drive the lock cylinder 400 to rotate, so that the lock cylinder 400 is switched to the unlocking state, and the door body is unlocked.

The fingerprint pencil 600 is the electrical connection spare that carries out the electricity with fingerprint collection module 500 in the fingerprint tool to lock, and the fingerprint tool to lock can be through fingerprint pencil 600 for fingerprint collection module 500 implementation power supply to/or control fingerprint collection module 500. The fingerprint wire harness 600 may be a coaxial wire or a common gold wire, and the specific kind of the fingerprint wire harness 600 is not limited in the embodiment of the present application.

In the present embodiment, the end of the fingerprint wire harness 600 extends into the door handle 100 via the clutch 200 and is electrically connected to the fingerprint acquisition module 500.

The spacer 300 plays a role of insulation. In the embodiment of the present application, the spacer 300 is disposed on the clutch 200, the spacer 300 is located between the fingerprint wiring harness 600 and the lock cylinder 400, and the spacer 300 isolates the portion of the fingerprint wiring harness 600 adjacent to the lock cylinder 400 from the lock cylinder 400.

Specifically, the spacer 300 may be a sheet-shaped spacer or a block-shaped spacer, and may be a structural member with other structures capable of realizing the insulating function. The specific shape of the spacer 300 is not limited by the embodiments of the present application.

The fingerprint lock disclosed in the embodiment of the application improves the structure of the fingerprint lock in the related art, and the isolation piece 300 is additionally arranged between the part, adjacent to the lock cylinder 400, of the fingerprint wire harness 600 and the lock cylinder 400, so that the corresponding part of the fingerprint wire harness 600 is isolated from the lock cylinder 400. In this case, in the case that the clutch 200 is in the separated state, the rotation of the clutch 200 with respect to the key cylinder 400 does not drive the fingerprint wire harness 600 to rub the key cylinder 400 due to the existence of the spacer 300 in the process that the user rotates the door handle 100, so that the abrasion of the fingerprint wire harness 600 can be relieved, and finally the service life of the fingerprint wire harness 600 can be prolonged.

Of course, since the fingerprint wiring harness 600 is not easily worn, there is no problem in that the fingerprint wiring harness 600 is easily worn to cause the electrical connection performance to be adversely affected.

As described above, since the spacer 300 is disposed between the corresponding portion of the fingerprint harness 600 and the lock cylinder 400, the spacer 300 may contact the lock cylinder 400, that is, the door handle 100, the clutch 200 and the spacer 300 may be rotated together during the rotation of the door handle 100, and thus, the spacer 300 and the lock cylinder 400 may be worn with each other. In order to mitigate wear, in one alternative, the spacer 300 may be a wear pad. For example, the spacer 300 may be a steel sheet, or a sheet-like structure made of a wear-resistant polymer nonmetallic material. The embodiments of the present application are not limited to a particular type of wear pad. Similarly, the lock cylinder 400 may be made of a wear resistant material to mitigate wear.

In the embodiment of the present application, the clutch 200 may have a cylindrical structure, and the inner cavity of the clutch 200 communicates with the inner cavity of the door handle 100. The sidewall of the clutch 200 (i.e., the wall of the clutch 200) may be provided with a threading hole 210, and the lock cylinder 400 is mounted at an inner port of the clutch 200 facing away from the door handle 100. The threading aperture 210 is disposed adjacent the inboard port. A first end of the fingerprint harness 600 is electrically connected to the fingerprint acquisition module 500. The second end of the fingerprint harness 600 passes through the threading hole 210 and extends out of the clutch 200. The spacer 300 is installed inside the clutch 200 and is located between the threading hole 210 and the lock cylinder 400.

In this case, since the threading hole 210 is opened on the cylinder wall of the clutch 200, the fingerprint wire harness 600 can be made to pass through the cylinder wall of the clutch 200, so that the fingerprint wire harness 600 does not need to pass through the inner side port of the clutch 200, and further can be kept away from the lock cylinder 400 as far as possible, which can further reduce the possibility that other areas of the fingerprint wire harness 600 are in contact with the lock cylinder 400.

Meanwhile, the clutch 200 is designed as a cylindrical structure, so that the fingerprint wire harness 600 passes through and enters the inner cavity of the door handle 100 to be connected with the fingerprint acquisition module 500. By the mode, part of the structure of the fingerprint wire harness 600 can be contained in the inner cavity of the door handle 100 and the inner cavity of the clutch 200, so that the purpose of restraining the fingerprint wire harness 600 is achieved, more compact distribution of the fingerprint wire harness 600 is facilitated, and the purpose of miniaturized layout is achieved. Of course, the spacer 300 is disposed in the clutch 200, i.e., the spacer 300 is disposed in the cylindrical cavity of the clutch 200, which is advantageous for achieving a more compact assembly of the spacer 300 and the clutch 200 and for reducing the space occupied by the two.

In the present embodiment, the spacer 300 may also be provided outside the clutch 200. The embodiments of the present application are not limited. As described above, the spacer 300 may be disposed within the clutch 200. Specifically, the spacer 300 may be fixed in the cylindrical cavity of the clutch 200 in a clamping manner, and this manner has the advantages of simple assembly and convenient disassembly, so that the disassembly of the operator can be realized to overhaul the internal structure of the clutch 200. In the embodiment of the present application, the spacer 300 may be disposed on the clutch 200 by means of clamping, bonding, riveting, welding, screwing, etc., and the embodiment of the present application does not limit the manner in which the spacer 300 is disposed on the clutch 200.

Of course, the clutch 200 may also be other structures, for example, the clutch 200 may be a solid structure. The embodiment of the present application is not limited to the specific structure of the clutch 200 as long as it can perform a clutch function.

The fingerprint harness 600 may be a loose fit or a tight fit with the threading hole 210. In a further embodiment, the fingerprint harness 600 is tightly fitted to the threading hole 210, so that the portion of the fingerprint harness 600 that is fitted to the threading hole 210 moves synchronously with the clutch 200. The matching manner can avoid relative sliding between the fingerprint wire harness 600 and the threading hole 210 when the clutch 200 rotates, thereby avoiding abrasion of the wall of the threading hole 210 to the fingerprint wire harness 600.

It should be noted that, in the embodiment of the present application, the tight fit between the fingerprint harness 600 and the threading hole 210 means that the fingerprint harness 600 does not play in the threading hole 210 when the fingerprint harness 600 is not subjected to an external force or the fingerprint harness 600 moves along with the clutch 200. Of course, in the design process, the diameter of the threading hole 210 may be designed to be smaller than the diameter of the fingerprint wire harness 600, and the fingerprint wire harness 600 may deform after passing through the threading hole 210, so as to be clamped in the threading hole 210, and finally, a tight fit between the fingerprint wire harness 600 and the threading hole 210 is achieved. Accordingly, a loose fit between the fingerprint harness 600 and the threading hole 210 means that play may occur in the threading hole 210 when the fingerprint harness 600 is not subjected to an external force or the fingerprint harness 600 follows the clutch 200.

The fingerprint lock disclosed in the embodiments of the present application may further include a lock case 700 and an elastic restoring member 820. The door handle 100 is rotatably provided to the lock case 700 so as to be rotatable with respect to the lock case 700. The clutch 200 may rotate with the door handle 100. One end of the elastic restoring member 820 is connected to the lock case 700, and the other end of the elastic restoring member 820 is connected to the clutch 200. In this case, the user holds the door handle 100 and rotates the door handle 100, and the door handle 100 rotates the clutch 200 to elastically deform the elastic restoring member 820. When the user removes the external force applied to the door handle 100, the elastic restoring member 820 is deformed to restore, and thus the clutch 200 and the door handle 100 are driven to restore by the elastic restoring force. In this process, the elastic restoring member 820 applies an elastic restoring force of restoring to the clutch 200 based on the lock case 700.

In a further embodiment, the elastic restoring member 820 may be a torsion spring, and the torsion spring may be sleeved on the clutch 200. The torsion spring has both ends connected to the lock case 700 and the clutch 200, respectively. This arrangement allows for a more compact assembly between the resilient return member 820 and the clutch 200 by providing an inner and outer sleeve. Of course, the elastic restoring member 820 may be a common coil spring, an elastic metal sheet, or the like, and the embodiment of the present application does not limit the specific kind of the elastic restoring member 820.

The fingerprint lock disclosed in the embodiment of the application may further include a reversing locking member 810, wherein one end of the elastic restoring member 820 is connected with the reversing locking member 810, and the reversing locking member 810 is connected with the end of the elastic restoring member 820 and the lock housing 700, so as to fix the elastic restoring member 820 on the lock housing 700.

The lock case 700 may be provided with a first locking hole 710 and a second locking hole 720. The first locking hole 710 and the second locking hole 720 are provided at opposite sides of the clutch 200, respectively. Specifically, with the door handle 100 oriented in the first direction, the reversing lock 810 is in locking engagement with the first locking hole 710; with the door handle 100 oriented in the second direction, the reversing lock 810 is in locking engagement with the second lock aperture 720, the first direction being opposite the second direction. Specifically, both the first direction and the second direction may be horizontal directions.

In this case, the reversing lock 810 is selectively engaged with the first locking hole 710 and the second locking hole 720 after being detached, so that the orientation of the door handle 100 can be adjusted, and thus the door handle 100 can be well adapted to the installation environment of the door.

In the case that the reversing locking member 810 is fixedly coupled to the first locking hole 710, an operator only needs to detach the reversing locking member 810 from the first locking hole 710 and then rotate the clutch 200 by rotating the door handle 100, so that the end of the elastic restoring member 820 coupled to the lock housing 700 is rotated to a position opposite to the second locking hole 720 and then is in locking engagement with the second locking hole 720 through the reversing locking member 810. Of course, in the case that the reversing locking member 810 is fixedly coupled to the second locking hole 720, the operator only needs to detach the reversing locking member 810 from the second locking hole 720 during operation, and then rotate the clutch 200 by rotating the door handle 100, so that the end portion of the elastic restoring member 820 coupled to the lock housing 700 is rotated to a position opposite to the first locking hole 710, and then is in locking engagement with the first locking hole 710 by the reversing locking member 810.

As can be seen from the above operation, in the reversing process of the door handle 100, the operator only needs to detach and install the reversing lock 810, and does not need to detach the door handle 100 and the clutch 200, so that the reversing operation of the door handle 100 can be simplified.

In this embodiment, the first locking hole 710 and the second locking hole 720 may be smooth holes (i.e., the hole wall is a smooth inner wall), and the reversing locking member 810 may be a plugging protrusion plugged into the smooth hole through an interference fit, and an end portion of the elastic restoring member 820 is connected (e.g., welded) to the plugging protrusion. The insertion protrusion is fixed in the light hole, thereby realizing the connection of the end of the elastic restoring member 820 with the lock case 700.

Of course, the first locking hole 710 and the second locking hole 720 may be threaded holes, and the reversing locking member 810 may be a threaded locking member, for example, the reversing locking member 810 may be a screw, a bolt, or the like. The end of the elastic restoring member 820 may be provided with a connection hole, and the threaded locking member may pass through the connection hole and be in threaded engagement with the threaded hole, and finally the nut of the threaded locking member compresses and fixes the end of the elastic restoring member 820 on the lock case 700, thereby achieving connection with the lock case 700.

The embodiment of the present application does not limit the specific kinds of the first locking hole 710 and the second locking hole 720. Of course, the specific type of reversing lock 810 is not limited by the embodiments of the present application.

In the embodiment of the present application, the clutch 200 may have various structures, for example, the clutch 200 may be a magnetic clutch mechanism, and the magnetic clutch mechanism generates magnetism when energized, so as to implement the adsorption connection to the lock cylinder 400, thereby switching to the engaged state. The magnetic clutch mechanism realizes demagnetization in the case of power failure, thereby realizing separation from the lock cylinder 400, and switching to a separated state.

Referring again to fig. 1-3, the clutch 200 may include an elastic positioning member 220, and the fingerprint lock disclosed in the embodiments of the present application may further include a linear motor 910 and a push plate 920. The push plate 920 is connected to the linear motor 910. The lock cylinder 400 includes a clutch fitting 410, and the clutch fitting 410 is provided with a positioning space. The linear motor 910 can push the elastic positioning member 220 to extend to a position matching with the positioning space through the push plate 920, so as to connect the clutch 200 with the lock cylinder 400. The push plate 920 is driven to move by the linear motor 910, so that the elastic positioning piece 220 and the positioning space are matched to realize connection, and the structure is simple and the manufacture is easy. In addition, the elastic positioning piece 220 has certain deformability, and can be well matched with the positioning space in a positioning way. After the linear motor 910 withdraws the pushing force, the elastic positioning member 220 is easily restored to a position separated from the positioning space, so that the clutch 200 is switched to the disengaged state.

In the embodiment of the present application, the clutch fitting 410 may be a square sleeve, and the clutch fitting 410 may be connected with other structures of the lock cylinder 400 through a plug-in fit manner. The embodiments of the present application are not limited.

In a further alternative, the push plate 920 may be an arcuate push plate. The center of the arc push plate may be located on the rotational axis of the door handle 100. In this embodiment, the push plate 920 has a larger area, and even if the clutch 200 is biased during rotation, the elastic positioning member 220 is still ensured to be located in the area where the push plate 920 is located, so that the elastic positioning member 220 can be better pushed by the linear motor 910.

In the embodiment of the present application, the number of the elastic positioning members 220 may be two, and the elastic positioning members are respectively located on two opposite sides of the clutch 200. With the door handle 100 oriented in the first direction, one of the elastic positioning members 220 is located opposite to the positioning space. With the door handle 100 oriented in the first direction, the other elastic positioning member 220 is in a position opposite to the positioning space. This structure can be well adapted to the reversing of the door handle 100, thereby ensuring the clutch function on the premise of reversing.

Referring to fig. 2, the clutch 200 includes a clutch body 230, and the clutch body 230 has a cylindrical structure and may be coupled to the door handle 100 by a fastener 830, and the clutch body 230 is coupled to the door handle 100, thereby enabling the clutch 200 to rotate following the door handle 100. In this case, the elastic positioning member 220 may be provided on the clutch body 230. Specifically, the elastic positioning member 220 may include a positioning column and a telescopic elastic member, where two ends of the telescopic elastic member are connected to the clutch main body 230 and the positioning column respectively, and the push plate 920 may push the positioning column, so that the positioning column is matched with the positioning space in a positioning manner, and at this time, the telescopic elastic member is elastically deformed. After the thrust of the linear motor 910 is withdrawn, the elastic restoring force of the telescopic elastic member can drive the positioning column to reset, so as to realize separation from the positioning space. Specifically, the telescopic elastic member may be a telescopic spring, a rubber structural member, a metal elastic bending piece, etc., which is not limited in this embodiment.
