Detailed Implementation
[0019] The technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.
[0020] Most existing bicycle locks are mechanical locks. Due to the structural design of the lock cylinder, mechanical locks have problems such as low security and fragile structure. They also require carrying a key, which makes them inconvenient.
[0021] like Figures 1-6 As shown, to solve the above problems, this embodiment proposes a multi-functional lock for bicycles, including a steel wire rope 10, a battery compartment 20, and a locking structure; the tail end of the steel wire rope 10 is fixed to the main body structure of the multi-functional lock, and the plug end is movably inserted into the plug lock hole 30 on the multi-functional lock; the steel wire rope 10 is wound around the outside of the main body structure of the multi-functional lock; the battery compartment 20 is built into the main body structure of the multi-functional lock and enters through a snap-fit structure that opens one side of the multi-functional lock housing; the locking structure is built into the main body structure of the multi-functional lock; the locking structure is connected to the plug end of the steel wire rope 10 inserted into the plug lock hole 30 and to the snap-fit structure, respectively realizing the pin fixing of the plug end of the steel wire rope 10 to the plug lock hole 30 or the pop-out disengagement of the plug end of the steel wire rope 10 from the plug lock hole 30, as well as the snap-fit fixing of the battery compartment 20 or the opening of the battery compartment 20.
[0022] Preferably, in this embodiment, the tail end and plug end of the wire rope 10 are respectively located at both ends of the multi-functional lock body structure, so that when the plug end of the wire rope 10 is inserted into the plug lock hole 30, the wire rope 10 can be spirally wound along the length direction of the multi-functional lock body structure. Not limited to, the wire rope 10 is wrapped with an elastic material, which helps the wire rope 10 to fit tightly against the body structure of the multi-functional lock in the wound state, and protects the wire rope 10 from scratches and damage from the bicycle frame in the locked state.
[0023] Preferably, in this embodiment, the length direction of the battery compartment 20 is the same as the length direction of the main body structure of the multi-functional lock, so as to further reduce the volume of the main body structure of the multi-functional lock. In this embodiment, the battery compartment 20 is used to assemble the battery module 40 and to supply power to part of the locking structure.
[0024] In this embodiment, a locking structure is used to control the steel wire rope 10 lock and the battery compartment 20 lock, which greatly simplifies the structure of the multi-functional lock while expanding its security and functionality.
[0025] More specifically, the locking structure includes a motor 50, a first cam 51, and a locking tongue 52; the motor 50 receives control signals transmitted from the outside and realizes the rotation of its own output shaft; the first cam 51 rotates synchronously with the output shaft; the locking tongue 52 is located on the rotation path of the first cam 51 and moves laterally under the push of the first cam 51; in the stationary state, the locking tongue 52 is located on the disengagement path between the plug end of the wire rope 10 and the plug locking hole 30.
[0026] Preferably, in this embodiment, a retractable push rod 53 is provided inside the plug locking hole 30, and a spring is sleeved on the push rod 53. The push rod 53 is located on the engagement path between the plug end of the wire rope 10 and the plug locking hole 30. When the plug end of the wire rope 10 enters along the depth direction of the plug locking hole 30, it squeezes the push rod 53 and the spring until it engages and fixes with the locking tongue 52 to achieve locking. When the motor 50 receives an external unlocking signal, it controls the output shaft to rotate, causing the first cam 51 to rotate to push the locking tongue 52 to retract. The push rod 53 naturally resets under the action of the spring and pushes out the plug end of the wire rope 10 to achieve unlocking.
[0027] Preferably, in this embodiment, the portion of the plug end of the wire rope 10 that is built into the plug locking hole 30 forms a recessed locking position that matches the end of the locking tongue 52. The recessed locking position is circumferentially distributed on the plug end of the wire rope 10, and its width should be slightly larger than the end of the locking tongue 52, so that the locking tongue 52 can enter the recessed locking position and prevent the plug end of the wire rope 10 from shaking in the plug locking hole 30 when locked.
[0028] Preferably, in this embodiment, the tip of the first cam 51 is upward in the static state, and the round end abuts against the folded edge of the latch 52; under the rotation of the output shaft, the first cam 51 rotates counterclockwise to 90°, and the tip rotates to the left to the horizontal left, gradually squeezing the folded edge of the latch 52 to make the latch 52 retract, so that the rotation angle and the degree of retraction of the latch 52 are proportional while ensuring the position of the rotating shaft.
[0029] Preferably, in this embodiment, the first cam 51 or the structural component that rotates synchronously with the first cam 51 is provided with a dual detection mechanism of time control and Hall effect sensing magnet, so that the rotation angle of the first cam 51 can be monitored in real time through the change of magnetic field, which can effectively monitor whether the first cam 51 has rotated to the correct position or whether the first cam 51 has been reset to the correct position.
[0030] In this embodiment, the rotation of the first cam 51 controls the retraction of the locking tongue 52, which pops the plug end of the wire rope 10 out of the plug lock hole 30. The direction of force transmission is clear and simple, ensuring the unlocking process of the plug end of the wire rope 10 with the multi-functional lock.
[0031] More specifically, the locking structure also includes an elastic element 55 that abuts against the outer side of the latch 52, and generates a tendency to push the latch 52 back to a stationary state when the latch 52 retracts laterally; the end face of the latch 52 facing the plug lock hole 30 is formed with a bevel, and the bevel is inclined downward along the direction of the connection between the plug end of the wire rope 10 and the plug lock hole 30; the latch 52 causes the plug end of the wire rope 10 to retract laterally during the insertion process of the plug end of the wire rope 10 and the plug lock hole 30 through the bevel, and when the plug end of the wire rope 10 is inserted and fixed to the plug lock hole 30, it returns to a stationary state and engages through the elastic element 55 to fix the plug end of the wire rope 10.
[0032] Preferably, in this embodiment, when the plug end of the wire rope 10 is inserted and fixed with the plug locking hole 30, the output shaft of the motor 50 reverses and returns to its original position, the first cam 51 and the locking tongue 52 are reset, and the plug end of the wire rope 10 is waited to be inserted and fixed with the plug locking hole 30 again.
[0033] Preferably, in this embodiment, the outer side of the locking tongue 52 protrudes to form a limiting post for the elastic member 55 to be sleeved and fixed, so as to ensure the continuous contact between the elastic member 55 and the locking tongue 52, effectively realizing the push and reset of the locking tongue 52 by the elastic member 55, and the locking tongue 52 to the plug end of the wire rope 10.
[0034] In this embodiment, without interference from the motor 50, the locking tongue 52 is stationary. The plug end of the wire rope 10 pushes the locking tongue 52 back along the inclined surface of the locking tongue 52 until the plug end of the wire rope 10 enters the plug locking hole 30 to a specific depth. Then, the locking tongue 52 is engaged with the plug end of the wire rope 10 under the action of the elastic member 55, thus realizing the locking process between the plug end of the wire rope 10 and the plug locking hole 30.
[0035] More specifically, the fastening structure includes a second cam 61 that rotates synchronously with the motor output shaft, and a fastening member 62 with one end located on the rotation path of the second cam 61, and the fastening member 62 rotates around its own fixed axis under the pressure of the second cam 61; a hook 621 is formed on the outer side of the other end of the fastening member 62; the housing of the multi-functional lock includes a base 72 and a battery cover 71 pivotally connected to one end of the base 72; a fastening groove is formed on the end face of the battery cover 71 facing the locking structure, which cooperates with the hook 621; after the plug end of the wire rope 10 is disengaged from the plug lock hole 30, the wire rope 10 is unwound, and when the motor 50 receives the transmitted control signal again, it controls the second cam 61 to rotate through the output shaft, and the fastening member 62 rotates to make the hook 621 disengage from the fastening groove, popping out the battery cover 71 to open the battery compartment 20.
[0036] Preferably, in this embodiment, the base 72 is a concave structure with a single-sided opening, and the battery cover 71 is an arched structure covering the opening of the base 72, and they are assembled to form a cylindrical multi-functional lock body structure.
[0037] Preferably, in this embodiment, a torsion spring is fitted on one end of the battery cover 71 that is pivotally connected to the base 72, so that when the hook 621 is disengaged from the fastening groove, the battery cover 71 will pop out instantly.
[0038] Preferably, in this embodiment, the fastening groove is provided on the symmetrical end face of the pivot end of the battery cover 71 and the base 72, and the fastening groove is provided on the central axis of the battery cover 71 to ensure the fastening effect of the hook 621 on the battery cover 71 and the base 72.
[0039] Preferably, in this embodiment, the fastening structure and the locking structure are respectively disposed on two vertical end faces to ensure that the wire rope 10 lock and the battery compartment 20 lock are independently distributed.
[0040] In this embodiment, the battery module 40 with the snap-fit structure provides security for the multi-functional lock. When the wire rope 10 is unwound, the snap-fit structure further ensures the identity of the multi-functional lock and the battery module 40.
[0041] More specifically, the first cam 51 and the second cam 61 are stacked on the same rotating shaft to achieve coaxial rotation; when the motor 50 receives the first unlocking signal transmitted from the outside, it controls the output shaft to rotate by a first preset angle, and the first cam 51 and the second cam 61 rotate synchronously by the first preset angle; when the motor 50 receives the second unlocking signal transmitted from the outside, it controls the output shaft to rotate by a second preset angle, and the first cam 51 and the second cam 61 rotate synchronously by the second preset angle; the first preset angle is less than the second preset angle; the locking tongue 52 is located on the rotation path of the first cam 51 when it rotates to the first preset angle; one end of the fastening member 62 is located on the rotation path of the second cam 61 from the first preset angle to the second preset angle.
[0042] Preferably, under the first unlock signal, the output shaft rotates 90° counterclockwise, causing the first cam 51 and the second cam 61 to rotate 90° counterclockwise; under the second unlock signal, the output shaft rotates 135° counterclockwise, causing the first cam 51 and the second cam 61 to rotate 135° counterclockwise.
[0043] Preferably, in this embodiment, in the initial state of the second cam 61, one end of the fastening member 62 abuts against the far end arc-shaped end. When the second cam 61 rotates, it moves from the far end arc-shaped end along the horizontal end to the other arc-shaped end until the original near end arc-shaped end presses down on the end of the fastening member 62. At this time, the fastening member 62 rotates and realizes the disengagement of the hook 621 from the fastening groove.
[0044] Preferably, in this embodiment, the second cam 61 has a built-in Hall effect sensor magnet for monitoring the rotation angle or reset state of the second cam 61. Since the first cam 51 and the second cam 61 rotate coaxially, the rotation angle or reset state of the first cam 51 can also be further monitored.
[0045] Preferably, in this embodiment, a torsion spring is sleeved on the rotating shaft of the fastening component 62, and the hook 621 on the fastening component 62 is triangular in shape, with its end face facing the battery cover 71 being inclined.

At this time, when the battery cover 71 is pressed down, it squeezes the fastening component 62 along the inclined surface of the hook 621, causing it to rotate until the hook 621 is engaged in the fastening position. Not limited to, since the motor 50 automatically resets after standing still for a few seconds, both the locking structure and the fastening structure automatically reset.

[0053] Preferably, in this embodiment, the wire rope 10 plug end inserted into the plug locking hole 30 can be judged by the degree of compression of the top rod 53 to determine whether the wire rope 10 plug end is locked and fixed. A micro switch is provided at the corresponding compression depth of the top rod 53. When the wire rope 10 plug end is locked and fixed, the micro switch can be used to determine whether the wire rope 10 forms a closed circuit, and the control module can further determine whether the closed circuit is broken.
[0054] In this embodiment, the anti-theft alarm function of the bicycle is realized by setting a buzzer when it is locked.
