DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the present invention provides a smart lock comprising a lock 100 for locking a bicycle and an electrical control box 200 for mounting a control circuit. The electric control box 200 is mounted on the lock head 100. The lock head 100 includes a lock case 110, a lock ring 120 movably disposed in the lock case 110, a spring 130 for providing a spring force to the lock ring 120, and a handle 140 for rotating the lock ring 120. . The lock ring 120 and the handle 140 are fixedly connected by at least two connecting rods 150. The lock housing 110 is provided with a running hole 160 for the connecting rod 150 to pass through, so that the locking ring 120 between the handles 140 is more firmly connected, and the handle can be effectively prevented from being broken. Or loose, saving maintenance costs.

In the present embodiment, the handle 140 and the lock ring 120 are fixedly connected by two links 150, wherein the length of one link is smaller than the length of the other link. Since the lock ring 120 is curved, such a design facilitates the mounting of the two links on the handle 140, and at the same time, the force of the two links 150 can be relatively uniform during the rotation. The stroke hole 160 is disposed on the side of the lock housing 110, and the two links 150 and the lock ring 120 are located on the same plane of rotation. Specifically, the handle 140 is provided with a mounting hole 141 for engaging with the connecting rod 150. The locking ring 120 is provided with a fixing hole 121. One end of the two connecting rods 150 is fixed on the fixing hole 121, and the other end is inserted into the mounting hole 141. The root links 150 are parallel to each other, so that the two links 150 are more evenly loaded. In order to make the engagement between the link 150 and the mounting hole 141 more tight, the end of the two links 150 that engages with the mounting hole 141 is provided with a knurling that increases friction, which further prevents the handle 140 from coming loose.

As shown in FIG. 4, one end of the electric control box 200 is mounted on the lock head, and the other end thereof extends in a direction perpendicular to the unlocking plane of the lock head 100. When the lock head 100 is mounted on the bicycle, the electric control box 200 is extended and looks like the tail of the bicycle, thereby improving the aesthetic appearance of the bicycle. In addition, the extension of the electronic control box 200 can provide sufficient installation space for the control circuit, avoiding the compact installation of the circuit on the lock head, and facilitating the maintenance of the circuit. The rotation direction of the lock ring 120 is an unlocking direction, and the rotation plane is an unlocking plane. In the present embodiment, one end of the electric control box 200 is mounted on the top of the lock 100, and an "L" shape is formed between the electric control box 200 and the lock 100.
