Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, and more specifically to a bicycle pedal lock capable of being unlocked by electric control. Background Art

[0002] With the improvement of living standards and sports concepts, bicycles have become one of the important choices for many people's leisure sports. As an important accessory of bicycles, cleats play a vital role in cycling. When cleats are used in conjunction with cleats, the rider's feet will be firmly fixed on the cleats after being locked, allowing the rider to pedal all the time during the ride. This design makes the rider's legs more balanced and the riding process more labor-saving. This advantage is particularly obvious during long-distance riding or climbing, and can significantly improve the efficiency and comfort of riding. Using cleats can also enhance riding safety. When riding on bumpy mountains or encountering small potholes on the road, ordinary pedals can easily cause the feet to be shaken off, increasing the risk of falling. Cleats can lock the rider's feet firmly on the pedals to prevent the feet from being separated due to bumps, thereby effectively reducing the risk of falling off the bike.

[0003] However, most existing cleats are purely mechanical, and riders need to rely on manual labor to unlock the cleats when using them. Most of the existing traditional cleat unlocking methods are: the rider manually determines whether the cleats need to be unlocked. When unlocking is required, the rider needs to twist the heel to be unlocked toward the outside of the body. At this time, the buckle on the shoe will resist the elastic force of the mechanical spring to make the buckle come out of the cleat. After the buckle comes out, the foot can be pulled back to detach from the cleat. In an emergency, users of traditional cleats will not be able to quickly complete the unlocking action due to untimely reaction or lack of proficiency in unlocking actions, resulting in a fall, which poses a high safety hazard. Utility Model Content

When the dead point limit arm leaves the dead point position, the electric-controlled pliers arm will rotate under the elastic force of the leaf spring, so that the electric-controlled pliers arm and the mechanical pliers arm are recessed The groove distance increases to complete unlocking; steering gear, steering blade, connecting rod, bearing; the steering gear is a power source and is provided with a spline output shaft; the steering blade is splinedly connected to the steering gear, the connecting rod is rotatably connected to the steering blade, the connecting rod is rotatably connected to the dead point limit arm, the bearing is rotatably connected to the dead point limit arm and abuts against the electric control clamp arm; using the mechanical dead point principle, when the rotating pair connecting the steering blade and the steering gear, the rotating pair connecting the connecting rod and the steering blade, and the rotating pair connecting the dead point limit arm and the connecting rod are in a straight line, the steering blade, the connecting rod, the bearing, the dead point limit arm ... The rod and the dead point limit arm form a dead point state. At this time, no matter how much the rotational force the dead point limit arm is subjected to, the mechanism cannot move; when in the dead point position, the electric control clamp arm abuts against the bearing installed on the same axis as the dead point limit arm and the connecting rod. At this time, no matter how much force the electric control clamp arm is subjected to, the mechanism cannot move; a plurality of bolts are respectively threadedly connected in each threaded hole; a circuit board; a wireless button, provided with an unlocking button, with a built-in electronic circuit, which communicates with the circuit board through a wireless connection, and can monitor whether the vehicle encounters an emergency situation that requires unlocking.

[0008] In a possible implementation, the end face of the force adjustment knob abuts against the end face of the mechanical clamp arm, and the force adjustment gasket abuts against the end face of the spring.

[0010] In a possible implementation, the circuit board is connected to the main frame through the bolts, and the steering gear is connected to the circuit board through bolts.

[0011] The utility model provides an electrically unlocked bicycle pedal lock, which has the beneficial effect that: compared with the prior art, the utility model provides an electrically unlocked bicycle pedal lock, which is provided with a main frame, a mechanical clamp arm, an electrically controlled clamp arm, a steering gear, a rudder blade, a connecting rod, a bearing, a dead point limit arm, a circuit board, a wireless button and other parts, and a groove is provided on the mechanical clamp arm and the electrically controlled clamp arm, in which the lock buckle installed on the locking shoe can be fixed. It is designed with emergency automatic unlocking, remote control unlocking and emergency mechanical unlocking functions. The electrically controlled clamp arm is locked using the mechanical dead point principle and can only be unlocked by electrical control. The locking and emergency mechanical unlocking are both achieved through the movement of the mechanical clamp arm. When performing electrical automatic unlocking or remote control unlocking, the steering gear provides power, the steering gear output shaft is spline-connected to the rudder blade, and the steering gear drives the rudder blade to rotate to drive the movement of the connecting rod and the dead point limit arm, thereby releasing the dead point state, thereby controlling the electrically controlled clamp arm to complete the unlocking action. The electric unlocking mechanism uses the dead point principle. When there is no need for electric unlocking, due to the mechanical dead point principle, even if the servo is powered off and does not provide any power, the electric clamp arm can be fully limited. When the mechanism is in the dead point state, no matter how much external force the electric clamp arm bears, there will be no angle change. When electric unlocking is required, the servo only needs to overcome the leaf spring elastic force to release the dead point state of the mechanism and complete the unlocking action; after unlocking, the servo rotates in the opposite direction by a certain angle to restore the locked state. The mechanical clamp arm is responsible for locking and emergency mechanical unlocking. When locking, insert the front end of the lock buckle on the locking shoe into the groove of the electric clamp arm, and then step down. The rear end of the lock buckle is designed with an inclined surface in the structure. When the foot steps down, the rear end of the lock buckle will squeeze the mechanical clamp arm. When the stepping force is greater than the spring elastic force, the mechanical clamp arm will be squeezed and yielded, and rotate around the axis to overcome the spring elastic force. When the lock buckle enters the locked position, the locking is completed. The utility model is also designed with an emergency mechanical unlocking function. If there is a problem such as an electronic unlocking failure or power exhaustion, the shoe can be released from the pedal by twisting the ankle toward the outside of the bicycle. At this time, the lock buckle overcomes the spring force of the mechanical clamp arm, and the lock buckle is released from the locked position to complete the unlocking. This mechanism design not only improves the speed and reliability of unlocking, but also enhances the stability and durability of the entire system.

When it is detected that unlocking is required or an unlocking command is received through wireless communication, the servo 7 is controlled to drive the rudder 8 to rotate, the system releases the dead point position, and the unlocking is completed.

[0043] As a specific implementation of the electronically unlocked bicycle pedal lock provided by the utility model, the circuit board 14 is connected to the main frame 1 through the bolts, and the steering gear 7 is connected to the circuit board 14 through the bolts.

[0044] The implementation principle of the electric-controlled unlocking bicycle pedal lock structure in the embodiment of the present application is as follows:

[0045] The utility model is designed with automatic unlocking, remote unlocking and emergency mechanical unlocking functions in emergency situations. The electric clamp arm 3 is locked by the mechanical dead point principle and can only be unlocked by electric control. The locking and emergency mechanical unlocking are both achieved through the movement of the mechanical clamp arm 2.

[0046] During the locking process, the front end of the lock buckle 15 on the locking shoe is inserted into the groove of the electric-controlled clamp arm 3, and then the foot steps downward. The rear end of the lock buckle 15 is structurally designed with an inclined surface. When the foot steps downward, the rear end of the lock buckle 15 will squeeze the mechanical clamp arm 2. When the stepping force is greater than the elastic force of the spring 5, the mechanical clamp arm 2 will be squeezed and retreated, overcoming the elastic force of the spring 5 and rotating around the axis. At this time, the distance between the mechanical clamp arm 2 and the electric-controlled clamp arm 3 becomes larger to accommodate the entry of the lock buckle 15. When the lock buckle 15 enters the locking position, the mechanical clamp arm 2 and the electric-controlled clamp arm 3 will firmly clamp the lock buckle 15 in the locking pedal to complete the locking.

[0047] When an emergency situation occurs during riding, such as emergency braking, an imminent fall, etc., the pedal lock will be automatically triggered to unlock. When automatically unlocked, the servo 7 provides power, and the output shaft of the servo 7 is spline-connected with the rudder plate 8. The servo 7 drives the rudder plate 8 to rotate and drive the connecting rod 9 and the dead point limit arm 11 to move, thereby releasing the dead point state. At this time, the bearing 10 installed on the dead point limit arm 11 no longer restricts the rotation of the electric-controlled clamp arm 3. The electric-controlled clamp arm 3 rotates around the second supporting shaft 13 with the support of the elastic force of the leaf spring 103, and the distance between the mechanical clamp arm 2 and the electric-controlled clamp arm 3 becomes larger, allowing the lock buckle 15 to come out, thereby controlling the electric-controlled clamp arm 3 to complete the unlocking action.

[0048] When the user unlocks the vehicle via the wireless button 16 installed on the handlebar, the unlocking command will be transmitted from the wireless button 16 to the circuit board 14 on the main frame 1 through the wireless unit. At this time, the servo 7 provides power, and the servo 7 drives the rudder blade 8 to rotate and drive the connecting rod 9 and the dead point limit arm 11 to move, thereby releasing the dead point state. The bearing 10 installed on the dead point limit arm 11 no longer restricts the rotation of the electric-controlled clamp arm 3. The electric-controlled clamp arm 3 rotates around the second supporting shaft 13 with the support of the elastic force of the leaf spring 103. The distance between the mechanical clamp arm 2 and the electric-controlled clamp arm 3 becomes larger, allowing the lock buckle 15 to come out, thereby controlling the electric-controlled clamp arm 3 to complete the unlocking action.

[0049] When encountering problems such as electronic unlocking failure or battery exhaustion, the emergency mechanical unlocking function can be used. The user can release the shoe from the pedal by twisting the ankle toward the outside of the bicycle. At this time, the buckle 15 overcomes the elastic force of the spring 5 on the mechanical clamp arm 2, so that the buckle 15 is released from the locked position and unlocked. This mechanism design not only improves the speed and reliability of unlocking, but also enhances the stability and durability of the entire system.

[0050] The utility model utilizes the dead point principle. When there is no need for electric unlocking, due to the effect of the mechanical dead point principle, even if the servo 7 is powered off and does not provide any power, the electric clamp arm 3 can be fully limited. When the mechanism is in the dead point state, no matter how much external force the electric clamp arm 3 is subjected to, the angle will not change. When electric unlocking is required, the servo 7 only needs to overcome the elastic force of the leaf spring 103 to release the dead point state of the mechanism and complete the unlocking action. After unlocking, the servo 7 can be reversely rotated by a certain angle to restore the locked state.

[0051] It is worth noting that the servo 7 shown in this embodiment is only one possible embodiment of the present invention. Similarly, in other embodiments of the present invention, the bicycle pedal lock with electric control unlocking can also use prime movers such as motors, electromagnets, and electromagnetic push rods.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
