Taking an electric vehicle as an example, an electric control lock is usually mounted on a front wheel of the electric vehicle, and a lock pin 3 of the electric control lock extends out to lock the wheel of the electric vehicle. Before riding, a user firstly makes the driving mechanism act, so that the driving mechanism drives the first push block 1 to slide, and the lock pin 3 is retracted into the lock shell 2; when the first push block 1 slides to the stroke end, the first push block 1 touches the first stroke switch 5, so that the electric door power supply module is conducted, and a user can twist the electric motor car electric door to ride. If the lock pin 3 is not opened before the user rides, the electric door power supply module is in an open circuit state, and even if the electric door of the electric motor car is screwed to supply power to the rear wheel of the electric motor car, the electric motor car cannot be driven to generate forward motion, and the user needs to unlock again and then ride. Therefore, in this embodiment, by providing the first travel switch 5 related to the unlocking action of the first push block 1 inside the electric control lock, the problem that the service life of the electrical element is affected by damage to the wheel components of the vehicle lock and the electric vehicle and by current surge in the circuit due to forgetting to unlock the vehicle lock by the user can be avoided.

The driving mechanism in this embodiment may be an electric driving unit or a manual driving unit, or both the electric driving unit and the manual driving unit may be present. The structure that the electric driving part and the manual driving part exist simultaneously is adopted in the embodiment, and when the parts of the electric driving part are damaged, the riding can still be achieved through manual unlocking. Specifically, the electric drive portion includes signal receiving module, motor 7 and drive chain, and signal receiving module is used for receiving the signal of unblanking to be connected with the motor 7 electricity, simultaneously motor 7 has power supply, and power supply can be the built-in battery of electric control lock, also can be the battery of electric motor car from taking, and the mode of connection of specifically supplying power to motor 7 is well known to the person skilled in the art, and this embodiment is not repeated here. The unlock signal may be a fingerprint signal, a swipe signal, a remote wireless signal, or other signal. After receiving the unlocking signal, the control module in the electric control lock or the electric vehicle controls the motor 7 to rotate, and the motor 7 slides the first push block 1 through the transmission chain to retract the lock pin 3. The manual driving part comprises a pull rope 8, one end of the pull rope 8 is connected with the first push block 1, and the other end of the pull rope extends to the outside of the lock shell 2 in the electric control lock and is used for pulling the first push block 1 to slide along the retraction direction of the lock pin 3, so that the lock pin 3 is finally retracted. After the manual unlocking, the pull rope 8 is fixed, so that the lock pin 3 is prevented from automatically extending. In order to avoid that a stranger pulls the pull rope 8 to unlock, the electric control lock in the embodiment further comprises a rope threading pipe 9, wherein the rope threading pipe 9 has certain flexibility and strength and is not easy to damage, and a specific structure can be reasonably selected by a person skilled in the art. The end of the rope threading pipe 9 is fixed in the lock shell 2, and the pull rope 8 is threaded in the rope threading pipe 9. The rope threading pipe 9 and the pull rope 8 finally extend into a storage space below the electric vehicle seat cushion, and when a user unlocks and opens the electric vehicle seat cushion, the pull rope 8 can be pulled to unlock manually, so that strangers are prevented from unlocking through the pull rope 8.

The transmission chain in the embodiment comprises a sliding block 10 which is arranged in the lock shell 2 in a sliding manner, wherein the sliding direction of the sliding block 10 is the same as that of the first push block 1, the sliding block 10 and the first push block 1 are connected through a first spring 11, and the deformation direction of the first spring 11 is parallel to that of the first push block 1; the slide block 10 is connected with the output shaft of the motor 7 in a transmission way. The motor 7 drives the first pushing block 1 to slide through the driving sliding block 10 and further through the first spring 11. When the pull cord 8 is pulled to unlock, the slider 10 does not move, and the pull cord 8 pulls the first push block 1 to slide and compresses the first spring 11. When the vehicle is locked, the pull rope 8 is loosened, the first spring 11 can push the first push block 1 out for resetting, and the lock pin 3 extends out of the vehicle for locking; when locking, the first push block 1 is separated from the first travel switch 5, and the switch power supply module is disconnected and cannot be ridden. And when the motor 7 locks the car, an electric signal is sent to the motor 7 again to lock the car.

When the pull rope 8 is pulled, the pull rope 8 drives the first push block 1 and the second push block 21 to move backwards simultaneously. A first matching block is arranged on the outer side surface of one first vertical plate 19 in a laterally extending manner, a first arc-shaped groove 22 is arranged on the first matching block, the opening direction of the first arc-shaped groove 22 faces the extending direction of the lock pin 3, a second arc-shaped groove 23 matched with the first arc-shaped groove 22 in shape is arranged on the second pushing block 21, and the bottom of the second arc-shaped groove 23 is abutted against the surface of the first arc-shaped groove 22; the first arc-shaped groove 22 and the second arc-shaped groove 23 are respectively provided with a radial opening, the end part of the pull rope 8 is provided with a clamping head 24 with the diameter larger than that of the radial opening, and the clamping head 24 is positioned in the second arc-shaped groove 23.

When the pull rope 8 is loosened, the first push block 1 rebounds under the action of the first push block 1, and the second push block 21 rebounds under the double action of the second spring 26 and the first spring 11.

The lock case 2 of the embodiment is also provided with a second travel switch 27 and a third travel switch 28, and the second travel switch 27 and the third travel switch 28 are respectively positioned at the travel end points of the second push block 21 and the sliding block 10 when the lock pin 3 is retracted; the third travel switch 28 is positioned at the bottom of the travel end point of the sliding block 10, a spring piece 29 is arranged on the third travel switch 28, and the spring piece 29 is positioned on the sliding path of the sliding block 10 and above the contact in the third travel switch 28; the spring piece 29 gradually slopes upward in the retracting direction of the lock pin 3. When the slider 10 slides to the end of the stroke, the bottom end of the slider 10 gradually contacts the spring piece 29, so that the spring piece 29 presses the third forming switch. The second travel switch 27 and the third travel switch 28 are arranged to detect the movement of the sliding block 10 and the second pushing block 21, so that internal faults of the electric control lock, such as incapability of timely rebound after long-time use of the first spring 11 and the second spring 26, can be found conveniently.
