Description

Technical Field

[0001] This invention relates to the field of electric bicycle safety protection technology, specifically an intelligent handlebar lock for electric bicycles. Background Technology

[0002] Currently, most electric bicycles on the market have purely mechanical handlebar locks, which typically consist of a lock cylinder, a lock tongue, and a slot on the frame stem. When locking, the user needs to mechanically rotate the lock housing to drive the lock tongue to extend and engage with the slot, thus restricting the direction of the bicycle and achieving the safety protection purposes of locking and preventing the bicycle from tipping over.

[0003] The existing technology has the following main drawbacks: it relies entirely on external force for rotation and cannot be integrated with the vehicle's intelligent control system (such as keyless start and remote App control); the lock tongue and the slot are in hard contact, and when the vehicle is subjected to external force or wind, the impact force is directly applied to the lock tongue, which can easily cause wear and deformation of the lock tongue, lock cylinder or slot, resulting in a high failure rate after long-term use; when unlocking, if there is internal stress in the front of the vehicle, the lock tongue may become stuck, requiring the handlebars to be shaken to unlock, which is laborious and damages the lock.

[0004] To address the above problems, this invention provides an intelligent handlebar lock for electric bicycles. Summary of the Invention

[0007] The front fork uses an upper and lower headset that are rotatably mounted inside the head tube;

[0008] A locking assembly, mounted on the head tube and fork, is used to limit the movement of the fork;

[0009] When the electric bicycle is being ridden, the locking component is in an anti-accidental activation state. When the electric bicycle needs to be locked after it has stopped, the locking component is activated by the intelligent control switch to lock the component.

[0020] Further, preferably, the limiting component includes:

[0021] A retaining ring is used to secure the front fork.

[0022] A limiting ring is rotatably mounted on the outer wall of the fixed ring, and two buffer grooves are symmetrically opened on its inner wall;

[0023] Multiple limiting holes are configured and evenly distributed around the circumference of the limiting ring;

[0024] Multiple anti-theft holes are configured and arranged circumferentially around the limiting hole, and located on the lower end face of the limiting ring.

[0026] Further, preferably, the driving component includes:

[0027] The drive rack is rotatably disposed within the lock base and meshes with the spur gear;

[0028] An arc-shaped plate is fixed to one end of the drive rack.

[0029] The fastener is fixed inside the lock base and located above the arc-shaped plate;

[0030] The pin is slidably disposed within the fixing member and is pushed into the limiting hole by the arc-shaped plate.

[0031] Furthermore, preferably, an electromagnet is fixed inside the arc-shaped plate, the pin is made of a magnetically attractable material, and the electromagnet is in the open state when the locking component is in the anti-accidental-touch state, and the electromagnet is in the closed state when the locking component is in the locked state.

[0032] Furthermore, preferably, the driving assembly further includes a fixed platform, which is fixed inside the lock base and has a support column slidably disposed inside it.

[0035] This invention utilizes an anti-accidental-touch state of the locking component to force the electromagnet to attract the pin during riding, ensuring that the pin will not enter the limiting hole on bumpy roads, thus avoiding the risk of accidental locking while riding and ensuring riding safety. By setting up a dual structure of limiting hole and anti-theft hole, when an external force rotates the drive rack, it ensures that the pin is always located in the limiting hole, improving the locking effect. Furthermore, the buffer spring of the limiting component can effectively absorb the impact of parking and automatically reset, significantly improving the lifespan of the core components. Through integrated control via the control circuit board, it supports various keyless operations and can be linked with the whole vehicle system (such as power off when locking the vehicle), realizing an intelligent vehicle use experience.

[0041] Reference Figures 1-4 This invention provides a technical solution: a smart handlebar lock for electric bicycles, comprising:

[0042] Head tube 1, fixed to the frame;

[0043] The front fork 2 is rotatably mounted inside the head tube 1 using an upper headset 3 and a lower headset 4;

[0044] Locking assembly 5 is installed on the head tube 1 and the fork 2 and is used to limit the fork 2.

[0045] When the electric bicycle is being ridden, the locking component 5 is in an anti-accidental activation state. When the electric bicycle needs to be locked after it has stopped, the locking component 5 is activated by the intelligent control switch, so that the locking component 5 is in a locked state.

[0046] In other words, when the electric bicycle is being ridden or in standby mode, the locking component 5 is in a partially operational state to prevent accidental locking on bumpy roads and improve riding safety.

[0047] In this embodiment, the locking component 5 includes:

[0048] The locking base 51 is fixed on the head tube 1 near the upper bowl assembly 3;

[0049] The limiting component 52 is rotatably disposed within the lock base 51 and is fixedly connected to the front fork 2;

[0050] The retaining ring 53 is fixed to the upper end face of the lock base 51 and closes the limiting component 52;

[0051] The control compartment 54 is fixed to the side wall of the lock base 51, and a control circuit board is fixed inside the control compartment 54.

[0052] The locking motor 55 is fixed inside the control compartment 54 and electrically connected to the control circuit board;

[0053] Bevel gear 56 is fixed at the output end of the locking motor 55;

[0054] The second bevel gear 57 is rotatably disposed within the control compartment 54 and meshes with the first bevel gear 56;

[0055] A spur gear 58 is fixed on the second bevel gear 57 and is disposed away from the first bevel gear 56;

[0056] The drive assembly 59 is installed inside the lock base 51 and meshes with the spur gear 58.

[0057] It should be noted that when riding, the motor 55 is locked and cannot be operated to prevent accidental activation of the smart control switch.

[0058] In a preferred embodiment, the limiting component 52 includes:

[0059] The retaining ring 521 is fixed to the front fork 2;

[0060] The limiting ring 522 is rotatably disposed on the outer wall of the fixed ring 521, and two buffer grooves 524 are symmetrically opened on its inner wall;

[0061] Multiple limiting holes 523 are configured and evenly distributed around the circumference of the limiting ring 522;

[0062] Multiple anti-theft holes are configured and arranged circumferentially around the limiting hole 523, and located on the lower end face of the limiting ring 522.

[0063] Preferably, two sliding plates 525 are symmetrically fixed to the outer wall of the fixed ring 521. The sliding plates 525 are slidably disposed in the buffer groove 524, and multiple sliding posts 526 are symmetrically fixed on both sides of the sliding plates 525. Buffer springs are sleeved on the sliding posts 526, and the rotation angle of the limiting ring 522 is ±5°.

[0064] In other words, when the locking component 5 is locked, the limiting ring 522 can rotate slightly through the buffer spring. Thus, when the electric bicycle is parked and is hit, the limiting ring 522 can rotate slightly to allow the buffer spring to absorb the impact energy and protect the core locking component. After the external force disappears, the spring drives the front of the bicycle to automatically return to the correct position, thus avoiding long-term stress damage.

[0065] In a preferred embodiment, the driving component 59 includes:

[0066] The drive rack 591 is rotatably disposed within the lock base 51 and meshes with the spur gear 58;

[0067] An arc-shaped plate 592 is fixed to one end of the drive rack 591;

[0068] The fastener 595 is fixed inside the lock base 51 and is located above the arc-shaped plate 592;

[0069] The pin 596 is slidably disposed within the fixing member 595 and is pushed into the limiting hole 523 by the arc plate 592.

[0070] In addition, an electromagnet is fixed inside the arc plate 592, the pin 596 is made of a magnetically adsorbable material, and the electromagnet is in the open state when the locking component 5 is in the anti-accidental contact state, and the electromagnet is in the closed state when the locking component 5 is in the locked state.

[0071] In other words, the electromagnet can force the curved plate 592 to attract the pin 596 during riding, ensuring that the pin will not enter the limiting hole 523 on bumpy roads, thus avoiding the risk of accidental locking while riding.

[0072] Preferably, the drive assembly 59 further includes a fixed platform 593, which is fixed inside the lock base 51, and a support column 594 is slidably arranged inside it. A support spring is provided between the support column 594 and the fixed platform 593. The support column 594 is always in contact with the bottom of the arc plate 592 by means of the support spring, and the support column 594 is arranged in a position corresponding to the pin 596.

[0073] In other words, the support column 594 and the support spring can always support the arc plate 592, thereby preventing the arc plate 592 from bending downwards and causing the pin 596 to be unable to be pushed.

[0074] Preferably, a torsion ring 597 is rotatably provided on the outer wall of the pin 596, and a torsion spring is provided between the torsion ring 597 and the pin 596. A plurality of guide posts 598 are fixed on the upper end face of the torsion ring 597, and when the torsion spring is not under force, the plurality of guide posts 598 are offset from the plurality of anti-theft holes, and the offset amount does not exceed the radius of the guide posts 598.

[0075] When locking is performed, the guide post 598 guides the pin into the anti-theft hole, causing the torsion ring 597 to rotate. At this time, the torsion spring is compressed, ensuring that when the arc plate 592 is slid by external force, the pin 596 will not disengage from the limit hole 523 due to gravity, thereby improving the anti-theft effect. When normal unlocking is required, the electromagnet is activated to attract the pin 596, thereby disengaging it from the limit hole 523 and completing the unlocking.

[0076] In practice, when riding or in standby mode: confirm that the locking motor 55 is in its original position and activate the electromagnet inside the arc plate 592 to generate a strong magnetic force. The position of the motor and the magnet will ensure that the pin 596 is attracted downwards, so that it is completely detached from the plane where the limit ring 522 is located and remains within the fixing part 595. At this time, even on bumpy roads, the pin 596 cannot extend, thus improving safety.

[0077] When the vehicle is locked (entering the locking state): A locking command is sent. After the user parks the vehicle, a locking command is sent via APP, remote control, electronic key or sensor module. The control circuit board receives the command and detects that the vehicle is stationary. The control circuit board first turns off the power to the electromagnet, the magnetic force disappears, and the pin 596 is in a free sliding state. Then, the locking motor 55 is driven to rotate, which makes the arc plate 592 rotate and pushes the pin 596 to slide upward and insert into the limiting hole 523. The guide post 598 is also inserted into the anti-theft hole, completing the double anti-theft.

[0078] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
