[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0028] A lock assembly of a padlock, such as Figure 1-5 As shown, it includes a motor 5, a lock body 1, a lock beam 2 and a locking member 6. The lock body 2 is provided with a motor 5, and the motor 5 is installed in the lock body 1. The output end of the motor 5 is provided with a follower 51, and one side of the lock beam 2 is provided with a locking groove 21 that matches the arc surface at one end of the locking member 6, and one side of the follower 51 is provided with a receiving groove 53 that matches the arc surface at the other end of the locking member 6.

[0029] The motor 5 drives the follower 51 to rotate, and the follower 51 and its receiving groove 53 push the locking member into the locking groove 21 to lock the lock beam; the motor 5 drives the follower 51 to rotate in the opposite direction to expose the receiving groove 53. When the lock beam 2 is pulled or pushed, the locking member 53 enters the receiving groove 53 under the action of the receiving groove 53, thereby unlocking the lock beam. The locking and unlocking of the lock beam is controlled by the locking member, and the installation of a lock pin on the follower 51 is avoided, which is conducive to reducing the volume of the follower 51 and facilitating the lightweight design of the padlock.

[0030] like Figure 2 and Figure 3 A motor mounting component 4 and a lock beam mounting component 3 arranged on one side of the motor mounting component 4 are provided in the lock body 1, the motor 5 is installed in the motor mounting component 4, one side of the lock beam is movably installed in the lock beam mounting component 3, a lock channel 32 is provided between the motor mounting component 4 and the lock beam mounting component 3, and the locking component 6 is movably installed in the locking channel 32.

[0031] like Figure 5 A cover plate 41 is provided on the upper side of the motor mounting member 4, a second limiting member 52 is provided on the upper side of the driven member 51, and a second limiting block 42 matching with the second limiting member 52 is provided on the lower side of the cover plate 41 to limit the rotation angle of the motor, which is also conducive to positioning the motor 4 and the driven member 51.

[0032] A limiting groove 22 is provided on one side of the locking beam 2, and a first limiting member 31 matching with the limiting groove 22 is provided on the locking beam mounting member 3 to limit the pulling range of the locking beam. A rotation groove 25 matching with the first limiting member 31 is provided on the lower side of the limiting groove 22. When the locking beam 2 is pulled to the outermost side, the locking beam 2 can be rotated.

[0033] The lower side of the lock beam mounting member 3 is provided with a spring and / or a proximity switch 33 that cooperates with the lock beam. The spring is used to provide unlocking power and can automatically pop out the lock beam, and the proximity switch is used to detect the unlocking state of the lock beam. The proximity switch can also be a button-type switch.

[0034] In a specific design, a battery is also provided in the lock body, and the battery 8 is electrically connected to the motor 5. A bottom groove 11 is provided on the lower side of the lock body, and the bottom groove 11 cooperates with a charging power source. A contact 12 is provided on the bottom groove 11, and the contact 12 is connected to the battery 8. Among them, the charging circuit and the external charging power source are prior art, and the utility model will not repeat them. However, the battery is not a necessary component of the lock assembly, for example, when an external power source can be provided, the motor can be driven.

[0035] like Figure 3 A guide member 15 and a receiving member 16 are arranged at intervals on the upper side of the lock body 1 . The guide member 15 cooperates with one side of the lock beam 2 , and the receiving member 16 cooperates with the other side of the lock beam 2 .

[0036] Sealing members, such as sealing rings, etc., may also be provided inside the receiving member 16 and the guiding member 15. The locking beam is in a U-shaped structure.

[0037] The utility model unlocks and locks by motor drive, and detects the unlocking and locking states of the lock beam, so as to timely find out the state of the padlock. The locking member 6 cooperates with the follower 51 and the lock beam 2, so that the follower 51 can be lightweight, which is beneficial to the design of the thickness of the lock body. The follower 51 can use a spherical body such as a steel ball or a steel ball, or a hemispherical body can be set on the two end faces of the rectangular parallelepiped. The lock assembly of the utility model can be used for active padlocks or passive padlocks.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
