The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

For a better understanding of the present invention, the structure of the existing electronic lock will be described first.

Fig. 1 is a schematic structural diagram of a conventional electronic lock. As shown in fig. 1, a conventional electronic lock includes a rotor 10 and a cylindrical locker 20, wherein the rotor 10 has a cylindrical shape and a locker hole 30 for inserting the locker 20; the latch 20 comprises a head 21 and a body 22, wherein the body 22 is cylindrical and the bottom surface is a plane parallel to the cylindrical generatrix.

Such a design makes the electronic lock in the locked state, relative sliding between the rotor 10 and the lock catch 20 is easy to occur, especially when shaking by foreign objects on the outside, the rotor 10 is easy to rotate, and after the rotation occurs, once the lock catch hole 30 and the main body 22 of the lock catch 20 are aligned, the lock catch 20 is inserted into the lock catch hole 30, resulting in an unexpected situation that the electronic lock is opened.

In order to solve the above problem, according to the present invention, there is provided an electronic lock including:

a latch including a head and a body, wherein the body is cylindrical and a bottom surface of the cylindrical is a slope forming a predetermined angle with a generatrix thereof,

Embodiments of the invention will now be described in detail with reference to specific embodiments and with reference to the accompanying drawings.

According to an embodiment of the present invention, a novel electronic lock is provided. The electronic lock may be any electronic lock known in the art, such as a circuit electronic lock, a chip electronic lock, a keyboard electronic lock, a biometric electronic lock, and the like, and the present invention does not limit the type of the electronic lock.

Fig. 2 is an exemplary structural schematic diagram of an electronic lock according to an embodiment of the present invention, wherein the electronic lock is in a locked state. As shown in fig. 2, the electronic lock includes a rotor 100 and a locker 200, wherein the rotor 100 is rotatable when unlocking and locking, and the locker 200 is used to lock an unlockable device.

Wherein, in order to facilitate the rotation of the rotor 100 when the rotor is properly unlocked, in one embodiment of the present invention, the rotor 100 is cylindrical. Further, the rotor 100 may be made of any suitable material known in the art, such as copper, iron, steel, any alloy, and the like, and the material of the rotor 100 of the present invention is not limited.

Specifically, rotor 100 includes a locking hole 110, a chamfer 120, and a groove 130.

The lock hole 110 is used for inserting the lock 200 to unlock the electronic lock. The shape of the latch hole may match the shape of the inserted portion of the latch 200, and may take the shape of a latch hole known in the art, such as a cylinder, where one base of the cylinder is on the side of the rotor 100 and the other base is inside the rotor 100, such that the entire latch hole 200 extends inside the rotor 100.

The chamfer 120 extends from the front face to the rear face of the rotor 100. In order to shorten the torque and save labor during unlocking, the tangent plane 120 can be close to one side of the locking hole 110. Illustratively, the chamfer 120 may be proximate a side of the catch hole 110 distal from the recess 130.

The groove 130 is used for reset, and extends from the front end surface to the rear end surface of the rotor 100.

The shackle 200 is used to lock the unlockable device and may be made of any suitable material known in the art, such as copper, iron, steel, and any alloy, and the material of the shackle 200 is not limited in this disclosure.

Specifically, the latch 200 includes a latch head 210 and a latch body 220. In embodiments of the present invention, the latch head 210 may take a shape known in the art, such as a shape that gradually widens from the upper portion to the lower portion.

The latch body 220 is adapted to be inserted into the latch aperture 110 to unlock the electronic lock. Thus, in one embodiment of the present invention, the latch body 220 is shaped to match the shape of the latch bore 110, for example, when the latch bore 110 is cylindrical, the latch body 220 is also designed to be cylindrical. In one embodiment of the present invention, the bottom surface of the locker body 220 is designed as a slope 230 forming a predetermined angle with its generatrix, and wherein the predetermined angle is such that the tangent surface 120 abuts tightly against the slope 130 when the electronic lock is in the locked state. In this way, in the locked state, no matter how the outside shakes, the rotor 100 does not rotate, and the electronic lock can be effectively prevented from being opened due to the shaking of the outside, so that the safety is improved.

For a more complete understanding of the present invention, the following describes the basic principles of the invention:

when the electronic lock is in the locking device, the lock catch body 220 of the lock catch 200 is not inserted into the lock catch hole 110 of the rotor 100, but the inclined surface 230 of the lock catch body 220 is tightly abutted against the tangent surface 120 of the rotor 100, because the tangent surface 120 and the inclined surface 230 are both flat surfaces, no matter how the outside shakes, the rotor 100 cannot rotate, thereby ensuring the safety;

when the electronic lock is unlocked correctly, the rotor 100 rotates to drive the tangent plane 120 and the inclined plane 230 to move relatively, and when the electronic lock rotates to align the lock hole 110 with the lock body 220, the lock body 220 is inserted into the lock hole 110, so as to unlock the electronic lock.

Thus, the present invention has been completed.

Further, the electronic lock of the present invention may further include a push rod 300 and a return spring 400 (not shown in the drawings). When the electronic lock is unlocked and the key is pulled out, the push rod moves forward under the action of the elastic force of the return spring 400, the push rod is provided with a small bulge, the small bulge slides along the groove 130, and the rotor 100 rotates towards the direction of the groove 130, so that the aim of locking the electronic lock by pulling out the key is fulfilled.

The present invention has been illustrated by the above embodiments, but it should be understood that the above embodiments are for illustrative and descriptive purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many variations and modifications may be made in accordance with the teachings of the present invention, which variations and modifications are within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
