[0037] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0038] In order to solve the problems in the prior art, the utility model provides a fingerprint lock, wherein an outer handle can rotate relative to an outer lock body shell, and the azimuth angle of the outer handle is locked via a buckle portion to adapt to various application scenarios.

[0039] like Figures 1a to 3c As shown, one embodiment of the utility model provides a fingerprint lock, comprising: an outer lock body connected to a door body;

[0040] The outer lock body includes:

[0041] An outer lock housing 1, which is mounted on the outer surface of the door body; and

[0042] The outer handle 2 is rotatably connected to the outer lock body housing 1, wherein the outer handle 2 includes:

[0043] A rotating shaft portion 21, the rotating shaft portion 21 is rotatably supported on the outer lock body housing 1, and rotates around a central axis perpendicular to the outer surface of the door body;

[0044] A support portion 22, the support portion 22 is connected to the first end of the shaft portion 21 and is in contact with the outer surface of the outer lock body housing 1; and

[0045] A hand-held portion 23, the hand-held portion 23 is connected to the second end of the rotating shaft portion 21 and is parallel to and spaced from the outer surface of the door body;

[0046] Among them, the outer lock body shell 1 has a plurality of snap-on parts 11 protruding from the outer surface of the outer lock body shell 1, and the support part 22 has a snap-on part 221 snap-fitting with the snap-on part 11, and the snap-on part 221 selectively snaps with one of the snap-on parts 11 to limit the azimuth angle of the outer handle 2 relative to the outer lock body shell 1.

[0047] In this embodiment, the outer lock body adopts an electronic unlocking method. Specifically, the outer lock body includes a fingerprint recognition component 3, which is connected to a microprocessor via a cable, and the microprocessor controls the opening and closing of the lock tongue according to the fingerprint comparison result.

[0048] The embodiment of the present application aims to provide a hardware configuration of an outer lock body capable of changing the azimuth angle, and does not attempt to improve the fingerprint recognition component 3 and microprocessor related to data processing, and the computer program on which the data processing depends.

[0049] It is understandable that the fingerprint lock of this embodiment further includes an inner lock body, which is fixed to one side of the inner surface of the door body, and the lock tongue can be installed between the inner lock body and the outer lock body, and the inner lock body and the lock tongue can be connected via, for example, a clutch shaft. Among them, this embodiment does not limit the connection method and unlocking method of the inner lock body and the lock tongue.

[0050] Specifically, the outer handle 2 is rotatably connected to the outer lock body housing 1, and the outer handle 2 is rotatably supported on the outer lock body housing 1 via the shaft portion 21, and the shaft portion 21 rotates around a central axis perpendicular to the outer surface of the door body. In the axial direction of the shaft portion 21, the side facing the door body has a support portion 22 that fits the outer surface of the outer lock body housing 1, and the side away from the door body is provided with a hand-held portion 23. The support portion 22 is used to support the outer handle 2 and to limit the position of the outer handle 2 in the axial direction. The hand-held portion 23 is used for the user's grip. Furthermore, the fingerprint recognition component 3 is provided on the outer surface of the outer handle 2 for collecting the user's fingerprint information for the microprocessor to perform unlocking verification. The shaft portion 21 is formed as a hollow cylinder, and the cable is passed through the shaft portion 21.

[0051] When the outer handle 2 rotates, the distance between the grip portion 23 and the door body does not change, and the support portion 22 always remains in contact with the outer surface of the outer lock body housing 1. The length of the shaft portion 21 in the axial direction determines the distance between the grip portion 23 and the door body.

[0052] Optionally, the outer surface of the handheld portion 23 may be further provided with an information collection device, such as a password input keyboard, a biometric information collection device, etc. Optionally, the above-mentioned information collection device may also be provided on the outer surface of the outer lock body shell 1. Based on the structure of the outer handle 2 of this embodiment that can rotate relative to the outer lock body shell 1, the position on the outer surface of the outer lock body shell 1 can be fully utilized without considering the problem of the outer handle 2 being blocked.

[0053] The distance between the hand-held portion 23 and the door body is locked, and the azimuth angle of the hand-held portion 23 relative to the outer lock body housing 1 is defined by the engagement of the snap portion 11 and the engaging portion 221. The snap portion 11 is provided on the outer lock body housing 1, and the engaging portion 221 is provided on the support portion 22. When the engaging portion 221 engages with the snap portion 11, the azimuth angle of the entire outer handle 2 relative to the outer lock body housing 1 is locked, and when the engaging portion 221 is released from the engagement with the snap portion 11, the outer handle 2 can rotate around the shaft portion 21 to adjust the azimuth angle relative to the outer lock body housing 1.

[0054] Among them, there can be multiple buckle parts 11, and only one engaging part 221 is set, then the setting position of the buckle part 11 corresponds to the preset position of the outer handle 2, when the engaging part 221 is engaged with any one of the buckle parts 11, the outer handle 2 is limited to the position corresponding to the buckle part 11.

[0055] In a specific example, the buckle portion 11 is formed as a button, and the buckle portion 11 has the following features: Figure 3a The first position shown protrudes from the outer surface of the outer lock body housing 1, and the second position is embedded in the interior of the outer lock body housing 1 in response to an external force;

[0056] The engaging portion 221 is formed as a through hole penetrating the supporting portion 22 , and the through hole is adapted to the key.

[0057] like Figure 3a As shown, the buckle portion 11 has a first position protruding from the outer surface of the outer lock body housing 1 and a second position pressed into the inner part of the outer lock body housing 1 by an external force, such as Figure 3b As shown, when the buckle portion 11 is pressed to the second position, the outer handle 2 can rotate around the shaft portion 21, and when the engaging portion 221 is not aligned with any of the buckle portions 11, the buckle portion 11 is pressed by the supporting portion 22 and maintained in the second position, thereby not limiting the rotation of the outer handle 2. Figure 3c As shown, when the outer handle 2 is rotated to the point where the snap-fitting portion 221 is aligned with the corresponding snap-fitting portion 11, the snap-fitting portion 11 will protrude from the outer surface of the outer lock body housing 1 due to the disappearance of the external force, so as to extend into the snap-fitting portion 221 to form a snap-fitting fit, thereby limiting the support portion 22 and the entire outer handle 2 in the rotation direction, thereby limiting the azimuth angle of the outer handle 2 relative to the outer lock body housing 1 to the position corresponding to the snap-fitting portion 11. When the snap-fitting portion 11 is not in the desired adjustment position, that is, the rotation path of the outer handle 2 needs to pass through more than one snap-fitting portion 11, the snap-fitting portion 11 can be pressed into the second position where it is not limited to the support portion 22 by external force, and then the outer handle 2 can be rotated continuously.

[0058] Specifically, Figure 2bAs shown, the key includes: a support spring 111 embedded in the outer lock body housing 1, a key body installed at the end of the support spring 111, and a key cap pressing the key body, wherein the natural length of the support spring 111 corresponds to the first position.

[0059] The keycap can be installed in the locking portion 221 of the support portion 22, wherein the edge of the keycap can have a flange edge that interferes with the inner surface of the locking portion 221 to prevent the keycap from being separated from the key position. The keycap is used to press the key body to a position flush with the inner surface of the support portion 22, which corresponds to the second position of the buckle portion 11, so that the buckle portion 11 does not form a limit with the support portion 22.

[0060] Based on the rotatable structure of the outer handle 2, the support portion 22 radially extends outward from the first end of the rotation shaft portion 21, and the support portion 22 is formed into a centrally symmetrical shape. The support portion 22 is formed into a circular or square shape, for example. In a specific example, the support portion 22 is formed into a square shape, and correspondingly, the engaging portion 221 can be formed as a through hole parallel to one edge of the support portion 22.

[0061] Among them, the distance between the buckle portion 11 and the shaft portion 21 is smaller than the distance between the edge of the support portion 22 and the shaft portion 21, and the support portion 22 is located within the positive projection range of the hand-held portion 23 within the outer lock body shell 1. The buckle portion 11 used to lock and unlock the azimuth angle of the outer handle 2 will always be visually blocked by the hand-held portion 23, which not only optimizes the appearance, but also avoids malicious operation by unrelated personnel.

[0062] Normally, the fingerprint lock of this embodiment needs to be installed by the installer to adjust the azimuth of the outer handle 2 according to the user's usage habits during installation, or the user can adjust it according to the usage habits after using it for a period of time. The locking and unlocking structure of the outer handle 2 of the fingerprint lock of this embodiment is simple, and the user can complete it without the guidance of professional installers, which can greatly reduce the installation and debugging costs and can give users a better user experience.

[0063] In a preferred example, the hand-held portion 23 is formed in a rectangular shape, and the fingerprint recognition component 3 is offset at the connection between the rotating shaft portion 21 and the hand-held portion 23 .

[0064] The fingerprint recognition component 3 can be set at a position corresponding to the position of the rotating shaft 21, or it can be offset from the position of the rotating shaft 21, which corresponds to the user's operating habits. When the hand-held portion 23 is formed in the shape of a rod-shaped handle, the fingerprint recognition component 3 is usually aligned with the rotating shaft 21, so that the hand-held portion 23 is held with four fingers wrapped around it, and the thumb is aligned with the fingerprint recognition component 3 to collect and identify the fingerprint. When the hand-held portion 23 is formed in a rectangular shape, the fingerprint recognition component 3 can be offset from the position of the rotating shaft 21, and is not limited to collecting the fingerprint of the thumb.

[0065] According to the conventional operation mode, in one embodiment, four buckle parts 11 may be included, and the arrangement directions of two adjacent buckle parts 11 are perpendicular to each other. Optionally, three buckle parts 11 may be included to correspondingly limit the outer handle 2 to the position as follows: Figure 1a to Figure 1c The three azimuths shown in .

[0066] Typically, the azimuth angle of the outer handle 2 relative to the outer lock body housing 1 is limited so that the long side direction of the grip portion 23 is along the horizontal direction or the vertical direction.

[0067] For example, a four-quadrant coordinate system is established with the position of the rotating shaft 21 as the coordinate origin, with the horizontal direction as the x-axis and the vertical direction as the y-axis. Under normal circumstances, the azimuth angle of the outer handle 2 can select 2 to 4 directions from the four directions of +x-axis direction, +y-axis direction, -x-axis direction, and -y-axis direction as the preset positions of the fingerprint lock of this embodiment, and the number and position of the buckle parts 11 are set accordingly. The number and position of the buckle parts 11 are positions that can be selected by the user. Figure 1a to Figure 1c As shown, when the azimuth angle of the outer handle 2 changes, the gap between it and the door edge will change accordingly. This can be selected and changed according to the opening direction of the door body, the distance between the door body and the door edge, the user's operating habits, etc., so as to be suitable for more application scenarios.

[0068] It can be seen from the above technical solution that the outer handle 2 is rotatably connected to the outer lock body housing 1, and the outer handle 2 is rotatably supported on the outer lock body housing 1 via the rotating shaft portion 21, and the rotating shaft portion 21 rotates around the central axis perpendicular to the outer surface of the door body. The distance between the hand-held portion 23 and the door body is locked, and the azimuth of the hand-held portion 23 relative to the outer lock body housing 1 is defined by the engagement of the buckle portion 11 and the engaging portion 221. Among them, the buckle portion 11 is arranged on the outer lock body housing 1, and the engaging portion 221 is arranged on the supporting portion 22. When the engaging portion 221 is engaged with the buckle portion 11, the azimuth of the entire outer handle 2 relative to the outer lock body housing 1 is locked, and when the engaging portion 221 is released from the engagement with the buckle portion 11, the outer handle 2 can rotate around the rotating shaft portion 21 to adjust the azimuth relative to the outer lock body housing 1.

[0069] Normally, the fingerprint lock of this embodiment needs to be installed by the installer to adjust the azimuth of the outer handle 2 according to the user's usage habits during installation, or the user can adjust it according to the usage habits after using it for a period of time. The locking and unlocking structure of the outer handle 2 of the fingerprint lock of this embodiment is simple, and the user can complete it without the guidance of professional installers, which can greatly reduce the installation and debugging costs and can give users a better user experience.

[0070] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model, and are not intended to limit the scope of protection of the utility model. Any equivalent implementation plans or changes that do not deviate from the technical spirit of the utility model, such as combination, division or repetition of features, should be included in the scope of protection of the utility model.
