Further, the equipment box 4 is fixedly connected to the vehicle frame 1 through equipment box mounting bolts 5 .

Further, the equipment box 4 is connected to the vehicle basket 10 through the vehicle basket installation rivet 9 , and the interior of the vehicle basket 10 is provided with a photovoltaic panel 11 .

Further, the lock tongue 71 is arranged correspondingly to the fastener hole 31 .

Specifically, the utility model provides a remote wireless remote control bicycle handle rotation lock, which is different from the existing bicycle lock structure, and the rotation lock can be used for shared bicycles/shared electric bicycles; the existing bicycle locks prevent the wheels from rotating Realize locking the car, and the car lock of this patent prevents the handlebar from rotating, so that the vehicle loses the function of riding because it cannot turn;

More specifically, the remote wireless remote control bicycle handlebar rotation lock has a compact structure, a concealed location, and is firmly installed in the device box 4, which is not easy to be damaged. As shown in Figure 1, from a conventional perspective, only the device can be observed The box 4 is a transitional installation between the vehicle basket 10 and the frame 1; the contact surface between the vehicle basket 10 and the equipment box 4 is actually the installation cover of the equipment box, and the two are connected by rivets 9, and the equipment box is an aluminum shell , The equipment box after riveting can be easily opened with high safety; the equipment box can only be opened by forcibly cutting off the rivets when maintenance is required.

More specifically, the buckle 3 is firmly welded on the front fork, and relative rotation is allowed between the equipment box 4 and the buckle 3 .

Furthermore, as shown in Figure 3, the equipment box 4 is electrically connected to the photovoltaic panel 11 on the vehicle basket 10, and the photovoltaic panel 11 charges the lithium battery 6, while the lithium battery 6 supplies power to the control circuit board 8 and the lock assembly 7 The control circuit board 8 includes a GSM/Bluetooth control module for receiving user unlocking instructions, a single-chip microcomputer for controlling logic, issuing motor rotation instructions, feedback lock unlocking status, sound and light alarms, etc., and the motor driver is used to drive the forward and reverse rotation of the DC motor; In the lock assembly, after the rotary motion of the DC motor 72 is changed through the first-stage worm gear-reduction, the second-stage cylindrical gear deceleration, and the third-stage rack and pinion, the dead bolt 71 is inserted into the fastener 3 to prevent the front fork 1 from rotating.

More specifically, Fig. 4 is the profile of the lock assembly; the lock housing 70 is the mounting frame for the worm gear, the worm, the gear, and the motor, and is also a guide groove for the rack and the dead bolt to slide, and also serves as the upper limit of the rack. stop and lower stop.

Further, as shown in Figure 5, it is the composition of the traditional mechanism of the lock assembly 7; the DC motor 72 rotates and is decelerated by the first-stage worm 73 and the first-stage worm gear 74, the second-stage first cylindrical gear 75 and the second-stage second cylindrical gear 76 After deceleration, the rotary motion is converted into linear motion by the three-stage spur gear 77 and the three-stage rack 78, the rack 78 compresses the spring 79 and pushes the dead bolt 71 to slide back and forth along the chute 701 of the lock housing 7; if the dead bolt 71 Insert it into the fastener hole 31 of the fastener 3, the movement of the fastener 3 relative to the equipment box 4 is restricted, that is, the front fork 1 cannot rotate relative to the frame 2, and the bicycle handle is locked and cannot be ridden; due to the worm gear transmission With a self-locking effect, the rotation of the motor 72 can push the lock tongue 71 to move forward and backward, but the lock tongue 71 cannot push the motor 72 to rotate in one direction; The front end of the dead bolt 71 is designed to have a certain slope, so that the dead bolt 71 can be easily inserted into the fastener hole 31; although there is an installation gap between the fastener 3 and the equipment box 4 to allow the two to rotate relatively, the The gap is so small that a blunt object cannot reach in and break the deadbolt.

More importantly, considering that most bicycles are in a natural parking state, the body is tilted to the left as a whole, and the handlebars rotate counterclockwise at a certain angle to maintain the balance of the bicycle, that is, the front fork 2 rotates clockwise relative to the frame 1, so When welding the fastener 3, the fastener hole 31 should be located on the right side of the frame 1. When parking the bicycle, the fastener hole 31 should rotate counterclockwise following the front fork 2. When the bicycle is parked, the fastener hole 31 should be aligned The deadbolt 71 is located near the deadbolt 71; when the vehicle is parked naturally, the deadbolt 71 may just be aligned with the fastener hole 31, or is located near the fastener hole 31; at this time, once the handlebar is deflected by an external force, the deadbolt 71 will be easily inserted into the fastener hole 31.

Further, as shown in Figure 6, the rack 78 slides back and forth in the chute 701; the lock housing 70 has an upper stop 703 and a lower stop 704 to prevent the rack 78 from slipping out of the chute; the lock housing is made of sheet metal The upper stop 703 is a bent flange at one end of the lock housing 70 , and the lower stop 704 is a protrusion punched out on the lock housing 70 .

Specifically, the turn handle lock has three working states, as shown in Figure 7a, a schematic diagram of the unlocking state, corresponding to Figure 8, at this time, the rack is located above the chute, the spring 79 is not compressed, and the dead bolt 71 is not protruding from the device box 4, so At this time, the front fork can rotate relative to the frame, that is, the operation of the handle is normal; Figure 7b is a schematic diagram of the waiting state, corresponding to Figure 9, at this time, the rack is located under the chute, the spring 79 is compressed, and the lock tongue 71 protrudes from the equipment box 4 Pressed on the fastener 3 but not inserted into the fastener hole 31, although the front fork can rotate relative to the frame at this time, once the handle is rotated to a specific angle by an external force, the lock tongue 71 and the fastener hole 31 When the positions coincide, the lock tongue 71 will be pushed into the fastener hole 31 by the spring 79, and the handle will be locked at random; Figure 7c is a schematic diagram of the locked state, corresponding to Figure 10, the rack is located below the chute, and the spring 79 will press the lock tongue 71 Inserting in the fastener hole 31, the relative rotation of the front fork 2 and the vehicle frame 1 is limited, and the bicycle cannot turn.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention , replacements and modifications, the scope of the present utility model is defined by the appended claims and their equivalents.
