[0060] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0061] The present invention provides an electronic padlock. In one embodiment, Figure 1-Figure 4 As shown, the electronic padlock includes a lock beam 1, a lock body shell 2, and an inner lock body 3 arranged in the lock body shell 2. Specifically, the volume of the inner lock body 3 is smaller than the volume of the inner cavity of the lock body shell 2, so that the inner lock body 3 matches the inner cavity of the lock body shell 2; wherein, the lock body shell 2 and / or the inner lock body 3 can be made of alloy material, and can be made by adopting processes such as die casting or casting, without limitation.

[0062] Specifically, a lock rod hole is provided on the lock body shell 2; the lock rod on the lock beam 1 is inserted into the lock rod hole, and a lock groove is provided on the lock rod; a cavity is formed between the lock body shell 2 and the inner lock body 3; the inner lock body 3 includes a drive motor (not shown in the figure), and the output shaft of the drive motor extends out of the cavity; the cavity includes a switch mechanism 4, a connecting mechanism 5 arranged on the output shaft, a barge shaft 6 arranged on the connecting mechanism 5, and a ball 7 arranged between the lock groove and the barge shaft 6. In the above embodiment, specifically, the connecting structure can be driven to rotate by the drive motor, so that the connecting mechanism 5 drives the barge shaft 6 to rotate, so that when the barge shaft 6 is rotated to a predetermined position, the ball 7 can move toward the groove on the barge shaft 6, and the ball 7 can remain separated from the lock groove, that is, the lock beam 1 can be pulled out to unlock the electronic padlock.

[0063] In the prior art, a limiting structure is usually provided to limit the rotation of the barge shaft 6, so that the rotation of the driving motor is limited by limiting the rotation of the barge shaft 6. In practical applications, frequent unlocking requires continuous rotation of the driving motor. In this process, the gears of the driving motor are subjected to the reaction force of the limiting structure, so that the driving motor may be damaged, thereby affecting the stability of the electronic padlock. In order to solve this problem, in one embodiment, as shown in FIG. Figure 1 , Figure 3-Figure 5 As shown, specifically, a first protrusion 511 and a second protrusion 512 are provided on the connecting mechanism 5, the switch mechanism 4 is provided next to the connecting mechanism 5, and the paddle 41 of the switch mechanism 4 is provided between the first protrusion 511 and the second protrusion 512, so that when the electronic padlock receives an unlocking command to control the driving motor to rotate in the positive direction, when the driving motor drives the first protrusion 511 to touch the paddle 41 to the first predetermined position, the electronic padlock controls the driving motor to stop rotating, and after a preset period of time, the electronic padlock controls the driving motor to rotate in the reverse direction, when the driving motor drives the second protrusion 512 to touch the paddle 41 to the second predetermined position, the electronic padlock controls the driving motor to stop rotating.

[0064] The following is an explanation of the actual use process. In an application scenario, such as Figure 5As shown, the current electronic padlock is in a locked state, and the paddle 41 can be pre-set on the left side of the second protrusion 512, so that the driving connection mechanism 5 can touch the paddle 41 through the first protrusion 511 when moving in the positive direction. Specifically, when the electronic padlock receives an unlocking instruction, the unlocking instruction can be, for example, receiving a password unlocking instruction, or receiving a fingerprint touch unlocking instruction or other unlocking methods, the electronic padlock controls the driving motor to rotate in the positive direction according to the unlocking instruction, and the positive direction rotation can be understood as rotating in the clockwise direction, so that the driving motor drives the connection mechanism 5 to rotate in the clockwise direction. When the connection mechanism 5 rotates to a predetermined position, the first protrusion 511 can touch the paddle 41 to the first predetermined position, and the first predetermined position can be the right side. Specifically, it can be pre-set according to the unlocking distance required to be rotated, so that when the paddle 41 is rotated to the right, the electronic padlock can control the driving motor to stop rotating.

[0065] In addition, after a preset period of time, for example, after 0.2S, the drive motor can also be controlled to reset. Specifically, the electronic padlock controls the drive motor to rotate in the opposite direction, which can be understood as rotation in the counterclockwise direction, that is, when the drive motor drives the second protrusion 512 to rotate in the opposite direction, the second protrusion 512 touches the paddle 41 to the second predetermined position, which can be the left side. The electronic padlock can control the drive motor to stop rotating. It can be understood that when the connecting mechanism 5 is rotated to the original position, by judging whether the paddle 41 is touched to the left, when the paddle 41 is rotated to the left, the electronic padlock controls the drive motor to stop rotating.

[0066] The electronic padlock in the above embodiment is provided with a connecting mechanism 5 that rotates synchronously with the drive motor, and a switch mechanism 4 for judging the rotation stroke of the drive motor, so as to determine whether the convex structure of the connecting mechanism 5 touches the paddle 41 of the switch mechanism 4 to a predetermined position, so that the electronic padlock confirms the rotation stroke of the connecting mechanism 5, and confirms the rotation angle of the drive motor through the rotation stroke of the connecting mechanism 5, so that the rotation angle of the drive motor can be determined through the connecting mechanism 5, so that there is no need to design a limit structure separately, so as to reduce the influence of the limit mechanism 8 on the drive motor, thereby improving the stability of the electronic padlock. In addition, in the above embodiment, since a reset process within a preset time period is also provided, it is also possible to make it possible to close the lock without the participation of the drive motor, thereby reducing the energy consumption of the drive motor and increasing the service life of the drive motor. This will be explained below in conjunction with specific embodiments.

[0067] In order to increase the stability of the electronic padlock, in one embodiment, the electronic padlock can be provided with a double ball structure, specifically, as Figure 2-Figure 4As shown, the locking rod hole includes a first locking rod hole 21 and a second locking rod hole 22; the locking beam 1 includes a first locking rod 11 and a second locking rod 12. When the locking beam 1 is installed, the first locking rod 11 is arranged in the first locking rod hole 21, and the second locking rod 12 is arranged in the second locking rod hole 22; the first locking rod 11 is provided with a first locking groove 111, and the second locking rod 12 is provided with a second locking groove 121; the barge shaft 6 is provided with a first groove 61 and a second groove 62; the ball includes a first ball 7a and a second ball 7b; the first ball 7a is provided between the first locking groove 111 and the first groove 61, and the second ball 7b is provided between the second locking groove 121 and the second groove 62.

[0068] In the above embodiments, it can be understood that by providing a double ball bearing and double lock groove structure, the tensile strength of the electronic padlock can be made stronger, thereby improving the safety performance of the electronic padlock.

[0069] It should be noted that the first locking rod 11, the second locking rod 12, the first locking slot 111 and the second locking slot 121 described above, wherein the first and the second mentioned are only for describing the relative positions of the locking rod and the locking slot, are only used for example and are not limited here.

[0070] In order to further improve the stability of the driving motor, in one embodiment, specifically, as Figure 3-Figure 7 ,as well as Figure 10-11 As shown, the electronic padlock further includes a limiting mechanism 8 disposed on the connecting mechanism 5 and disposed at the bottom of the barge shaft 6, that is, the limiting mechanism 8 is disposed on the connecting structure, and the barge shaft 6 is disposed on the limiting mechanism 8, specifically:

[0071] The limiting mechanism 8 is provided with a first annular groove 81 and a second annular groove 82; the bottom of the barge shaft 6 is provided with a first outer pin 631 and a second outer pin 632, the first outer pin 631 is arranged in the first annular groove 81, and the second outer pin 632 is arranged in the second annular groove 82. In the above embodiment, the annular groove structure on the limiting mechanism 8 can limit the rotation stroke of the barge shaft 6, so as to avoid the driving motor controlling the barge shaft 6 to rotate excessively when the switch mechanism 4 fails, so as to improve the stability of the electronic padlock.

[0072] In one embodiment, specifically, Fig.10 and Fig.11As shown, a protrusion structure 83 with a predetermined angle is provided at the bottom of the limiting mechanism 8, and the protrusion structure 83 is a non-closed structure; illustratively, the predetermined angle can be, for example, 240°, that is, a 120° open annular groove is provided on the outer side of the protrusion structure 83, specifically, the first protrusion 511 and the second protrusion 512 are arranged between the first side wall 841 of the protrusion structure 83 and the second side wall 842 of the protrusion structure 83, that is, the first protrusion 511 and the second protrusion 512 are arranged in the 120° open annular groove. Among them, in the initial state, the first protrusion 511 of the connecting mechanism 5 can be arranged next to the first side wall 841, and the paddle 41 of the switch mechanism 4 can be arranged on the left side of the second protrusion 512. In this way, when the driving motor rotates in the positive direction, the second protrusion 512 leaves the paddle 41, and when the second protrusion 512 approaches the second side wall 842, the driving motor drives the first protrusion 511 to touch the paddle 41 to the first preset position. At this time, the first protrusion 511 is located on the left side of the paddle 41. When the driving motor is controlled to rotate in the opposite direction to reset the driving motor, the driving motor drives the first protrusion 511 to leave the paddle 41, and when the first protrusion 511 approaches the first side wall 841, the driving motor drives the second protrusion 512 to touch the paddle 41 to the second preset position. At this time, the limiting structure can limit the connecting mechanism 5. In the above embodiment, by providing a limiting mechanism 8 on the connecting mechanism 5, when the switch mechanism 4 fails, the limiting mechanism 8 can also limit the connecting mechanism 5 to limit the driving motor, thereby improving the stability of the electronic padlock.

[0073] In one embodiment, specifically, Figure 2 , Figure 3 ,as well as Figure 6-Figure 9 As shown, specifically, the connecting mechanism 5 includes a connecting base 51 and a connecting member 52; wherein, a connecting column 513 is provided on the connecting base 51, a through hole is provided in the middle of the limiting mechanism, and the limiting mechanism is sleeved on the connecting column 513 through the through hole; a convex point structure is also provided on the connecting column 513, and a groove structure is provided at the bottom of the connecting member, and the groove structure is matched and connected with the convex point structure so that the connecting member 52 is arranged on the connecting column 513.

[0074] Specifically, the bottom of the barge shaft 6 is also provided with a first inner pin 641 and a second inner pin 642, one end of the first inner pin 641 and one end of the second inner pin 642 form a first limit interval 643a, and the other end of the first inner pin 641 and the other end of the second inner pin 642 form a second limit interval 643b; one end of the connecting member is arranged in the first limit interval 643a, and the other end of the connecting member is arranged in the second limit interval 643b. In actual operation, the connecting member arranged on the connecting mechanism is driven to rotate by the driving motor, so that the connecting member drives the barge shaft to rotate. In the above embodiment, by arranging the connecting member 52 between the first inner pin 641 and the second inner pin 642 at the bottom of the barge shaft 6, the barge shaft 6 can be synchronously rotated by the connecting member 52, and it is convenient to install and disassemble the barge shaft 6 and the connecting member 52.

[0075] In one embodiment, specifically, Figure 4 and Figure 5 As shown, the limiting mechanism 8 further includes a first shock absorbing member 841a and a second shock absorbing member 841b, wherein: the first shock absorbing member 841a is arranged beside the first side wall 841; the second shock absorbing member 841b is arranged beside the second side wall 842. Specifically, the shock absorbing member can be made of, for example, a silicone material, so that when the first protrusion 511 moves toward the first side wall 841, the first shock absorbing member 841a can have a certain buffering effect on the first protrusion 511, and when the second protrusion 512 moves toward the second side wall 842, the second shock absorbing member 841b can have a certain buffering effect on the second protrusion 512, thereby further improving the stability of the driving motor.

[0076] In one embodiment, specifically, Figure 2-Figure 4 As shown, the electronic padlock further includes a flat-shaped rebar spring 9 , wherein the rebar spring 9 is arranged on the limiting mechanism 8 , and the rebar 6 is arranged on the rebar spring 9 .

[0077] The second locking rod 12 is also provided with an annular locking groove 122, wherein the flat-shaped shaft spring 9 can be a plane scroll spring, which is also called a clockwork spring. It can be understood that a plane scroll spring is a spring with one end fixed and the other end acting with torque; under the action of torque, the spring material produces bending elastic deformation, causing the spring to twist in the plane. Specifically, one end of the shaft spring 9 can be fixed, and one of the pins of the shaft can be hooked with the other end of the shaft spring, so that when the shaft spring 9 is rotated, the other end of the shaft spring 9 produces bending elastic deformation. The following is an example with reference to a specific scenario, such as Fig.12 and Fig.13As shown, based on the first inner pin 641 and the second outer inner pin 642 provided at the bottom of the revolving shaft 6, a movable end 91 and a fixed end 92 can be led out from the revolving shaft spring 9, wherein the fixed end 92 of the revolving shaft spring 9 can be fixedly provided in the main shell of the lock body, and the second inner pin 642 of the revolving shaft 6 can be provided on the movable end 92, so that when the lock is unlocked, the connecting mechanism 5 is driven by the driving motor to rotate, so as to drive the revolving shaft 6 to rotate through the connecting mechanism 5, so that when the revolving shaft 6 drives the movable end 91 to rotate, the revolving shaft spring 9 generates a rebound force, and at this time, the lock beam 1 can be pushed out by the elastic member provided at the bottom of the second lock rod hole 22, and the second ball 7b is provided between the second groove 62 and the annular lock groove 122. Based on the reset process within a preset time period set in the above embodiment, when locking is required, the lock beam 1 can be pressed so that when the lock beam 1 is pressed downward, the first ball 7a moves to the first lock groove 111, and the second ball 7b moves to the second lock groove 121. At this time, the bending elastic deformation accumulated by the barge shaft spring 9 can generate a rebound force to drive the barge shaft 6 to reset to the locked state. It can be understood that in this process, the barge shaft is driven to rotate back to the locked state by the barge shaft spring, and the participation of the drive motor is not required. In the above embodiment, by setting the barge shaft spring 9, the barge shaft 6 can be driven back to the original position by the barge shaft spring 9 when locking, thereby reducing the energy consumption of the drive motor and increasing the service life of the drive motor.

[0078] In one embodiment, a battery compartment (not shown in the figure) is further provided in the inner lock body 3, and the battery compartment is used to assemble batteries. A first electrode connection terminal may be provided in the battery compartment, and the first electrode connection terminal may be a negative terminal. A second electrode connection terminal may be provided on the battery cover, and the second electrode connection terminal may be a negative terminal. The battery cover is provided at the bottom of the inner lock body. Specifically, the battery cover may be provided at the bottom of the inner lock body by providing a threaded hole and a threaded connector.

[0079] In one embodiment, Figure 1-Figure 4 As shown, the lock body shell 2 also includes a bottom cover 23 and a rubber ring B. The bottom of the lock body shell 2 is also provided with a groove structure and a bottom cover mounting hole (not shown in the figure), wherein: one end of the bottom cover is provided with a protruding structure matching the groove structure, and the protruding structure is embedded in the groove structure; the other end of the bottom cover is provided with an opening, and the rubber ring is arranged on the bottom cover mounting hole, and is passed through the opening, the rubber ring B and the bottom cover mounting hole through a connecting piece, and the connecting piece can be a screw or a screw, etc., and is not limited, so that the bottom cover can be installed on the lock body shell.

[0080] In the above embodiment, the structure of the electronic lock body can be further strengthened by providing a battery cover 33 on the inner lock body 3 and a bottom cover 23 on the bottom of the lock body shell 2.
