[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] See also Figures 1 to 5 The utility model provides a technical solution: a single fingerprint padlock, comprising a padlock bottom cover 12 and a padlock face shell 1, the top of the padlock face shell 1 is clamped with the padlock bottom cover 12, the surface of the padlock face shell 1 is installed with a fingerprint identification component 2, the bottom of the fingerprint identification component 2 is installed with a main board 3, a battery 4 is installed inside the padlock bottom cover 12, a motor 5 is installed inside the padlock bottom cover 12, the output end of the motor 5 is fixedly connected to an eccentric shaft 6, a lock tongue spring 8 is fixed inside the padlock bottom cover 12, the end side of the lock tongue spring 8 is fixed with a clamping lock tongue 7, and the end side of the clamping lock tongue 7 is clamped with a padlock lock beam 9.

[0033] It should be noted that the mainboard 3, motor 5, battery 4 and fingerprint recognition element 2 are electrically connected. The fingerprint recognition lock adopts semiconductor biological live fingerprint recognition technology. Through the semiconductor capacitive fingerprint head, it can quickly and efficiently identify the correct fingerprint of the unlocker, which can prevent the unlocking of false fingerprint films, thereby ensuring the security of the fingerprint padlock. The fingerprint recognition element 2 belongs to the existing technology in this field, so it will not be described in detail.

[0034] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a cover pin 101 is fixed between the padlock cover 1 and the padlock bottom cover 12 , and a decorative piece 102 is installed on the surface of the padlock cover 1 .

[0035] It should be noted that the padlock face shell 1 and the padlock bottom cover 12 are fixed by face shell pins 101, which can be removed when disassembly is required.

[0036] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a recess for engaging with the locking tongue 7 is provided at the bottom of the padlock beam 9 .

[0037] It should be noted that a notch is provided at the bottom of the padlock beam 9 , which is consistent with the locking tongue 7 . When the locking tongue 7 is engaged with the notch, the notch will be limited so that the padlock beam 9 cannot shake.

[0038] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a lock beam spring 11 is fixed to the bottom of the padlock lock beam 9, and a cavity is opened inside the padlock bottom cover 12 to facilitate the movement of the padlock lock beam 9. The lock beam spring 11 is fixedly connected to the bottom surface of the cavity inside the padlock bottom cover 12.

[0039] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a lock beam pin 10 is mounted on the surface of the padlock bottom cover 12 .

[0040] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a support block is fixed on the surface of the padlock bottom cover 12 to facilitate the installation of the lock tongue spring 8.

[0041] It should be noted that a support block is installed inside the lock, and the lock tongue spring 8 is connected to it. At the same time, an empty groove is provided inside the lock housing, and the support block can be slidably mounted thereon.

[0042] The use method and advantages of this utility model: When the single fingerprint padlock is working, the working process is as follows:

[0043] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, when the padlock needs to be locked, the padlock beam 9 is pressed downward, and the padlock beam 9 immediately slides down into the cavity in the padlock bottom lock cover and squeezes the lock beam spring 11. When the padlock beam 9 slides down, it hits the padlock tongue, and the padlock tongue is forced to squeeze the lock tongue spring 8 until the notch of the padlock beam 9 and the padlock tongue are at the same horizontal plane. The lock tongue spring 8 then resets and drives the padlock tongue to fit into the notch of the padlock beam 9, so that the padlock is locked.

[0044] When the unlocker needs to unlock the padlock, he first presses the pre-set correct fingerprint on the fingerprint recognition element 2. The fingerprint recognition element 2 recognizes the correct fingerprint and transmits an electrical signal to the motor 5. After receiving the electrical signal, the motor 5 starts and drives the eccentric shaft 6 to rotate to one side. After the eccentric shaft 6 rotates, the locking tongue 7 is released and reset by the elasticity of the locking tongue spring 8, so that the locking tongue 7 moves to the notch away from the lock beam, so that the locking tongue 7 is separated from the lock beam and the lock beam is driven to slide up by the elasticity of the lock beam spring 11. At this time, the lock beam can be pulled upward, that is, the fingerprint padlock is unlocked.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Persons skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
