[0017] As shown in Figure 1 and Figure 3 shown, the electric locomotive head lock comprises a housing 1, a motor 9 and a lock tongue 2. The electric locomotive head lock is used for being mounted on a motorcycle, when a circuit control system on the motorcycle controls the motor 9 to drive, the motor 9 drives the lock tongue 2 to act, the lock tongue 2 is extended to realize locking, and the lock tongue 2 is retracted to realize unlocking.

[0018] As shown in Figure 2As shown, the mounting seat 3, the first micro switch 6 and the second micro switch 7 are mounted in the shell 1, the first transmission member 4 is slidably arranged on the mounting seat 3, the motor 9 is in transmission connection with the first transmission member 4, the first transmission member 4 is in transmission connection with the second transmission member 5, and the second transmission member 5 is connected with the lock tongue 2, so that the motor 9 can drive the first transmission member 4, the second transmission member 5 and the lock tongue 2 to move together; the first transmission member 4 is provided with a first acting portion 40, when the first transmission member 4 moves forward by a set distance, the first acting portion 40 can act on the first micro switch 6; the second transmission member 5 is provided with a second acting portion 50, when the second transmission member 5 moves backward by a set distance, the second acting portion 50 can act on the second micro switch 7, and the first micro switch 6 and the second micro switch 7 are electrically connected with the motor 9.

[0019] When locking is needed, the motor 9 drives the first transmission member 4 to move forward, the first transmission member 4 drives the second transmission member 5 to move forward, and the second transmission member 5 drives the lock tongue 2 to move forward, since the first transmission member 4 is provided with the first acting portion 40, when the first transmission member 4 moves forward by a set distance, the first acting portion 40 acts on the first micro switch 6, the first micro switch 6 transmits a signal to the motor 9, and the motor 9 stops driving, at this time, the lock tongue 2 is in an extended state, so that locking is realized. When unlocking is needed, the motor 9 drives the first transmission member 4 to move backward, the first transmission member 4 drives the second transmission member 5 to move backward, and the second transmission member 5 drives the lock tongue 2 to move backward, since the second transmission member 5 is provided with the second acting portion 50, when the second transmission member 5 moves backward by a set distance, the second acting portion 50 acts on the second micro switch 7, the second micro switch 7 transmits a signal to the motor 9, and the motor 9 stops driving, at this time, the lock tongue 2 is in a retracted state, so that unlocking is realized. The work of the motor 9 is controlled by the two micro switches, the movement of the lock tongue 2 can be accurately and stably controlled, the motor 9 is prevented from overloading, and the stability of the vehicle head lock is improved.

[0020] In order to realize unlocking in the case of failure of the motor 9 or the control circuit, Figure 4 As shown, the first transmission member 4 is provided with a spring positioning groove 43, and the first spring 11 is arranged in the spring positioning groove 43, as shown in Figure 5As shown, the second transmission member 5 is provided with a spring clamping groove 52, the first spring 11 is located in the spring clamping groove 52, and the two ends of the first spring 11 can act on the two end inner walls 53 of the spring clamping groove 52 respectively. The second transmission member 5 is provided with a cable slot 51 for connecting with the cable. When the motor 9 is working normally, the motor 9 drives the first transmission member 4 to move, the first transmission member 4 drives the first spring 11 to move, the end of the first spring 11 acts on the inner wall 53 of the spring clamping groove 52 of the second transmission member 5, thereby driving the second transmission member 5 to move, so that the second transmission member 5 drives the lock tongue 2 to move. When the motor 9 or the control circuit fails, the cable can be pulled by a mechanical key or other control mode, and the cable pulls the second transmission member 5 to move backward, so that the second transmission member 5 moves backward relative to the first transmission member 4 (since the motor 9 does not drive, the first transmission member 4 does not move), and the first spring 11 is compressed, so that the second transmission member 5 drives the lock tongue 2 to move backward, thereby realizing unlocking; when locking is needed, the second transmission member 5 can drive the lock tongue 2 to move forward under the action of the first spring 11, thereby realizing locking. Through this structure, even if the motor 9 or the control circuit fails, unlocking or locking can be realized by mechanical mode, so that the vehicle head lock has double protection.

[0021] In order to facilitate the placement of the first spring 11 and facilitate assembly, the spring positioning groove 43 is provided with a positioning column 44 at both ends, and the two ends of the first spring 11 are respectively sleeved outside the two positioning columns 44. In this way, the first spring 11 is placed in the spring positioning groove 43, and the two ends of the first spring 11 are positioned by the two positioning columns 44 and cannot fall out of the spring positioning groove 43.

[0022] As shown in Figure 2 The second spring 12 is sleeved outside the lock tongue 2, one end of the second spring 12 acts on the second transmission member 5, and the other end of the second spring 12 acts on the inner wall of the shell 1. The second spring 12 can make the second transmission member 5 move forward with a buffering process, so that the lock tongue 2 enters the lock groove more stably; in addition, the second spring 12 will give the second transmission member 5 a backward force, so that when the cable is needed to be used, the second transmission member 5 can more easily move backward with the lock tongue 2, thereby realizing unlocking.

[0023] As shown in Figure 3 A rotatable rotating shaft 80 is installed on the mounting seat 3, the rotating shaft 80 is in transmission connection with the motor 9, the upper end of the rotating shaft 80 is connected with the upper gear 8, the first transmission member 4 has a tooth surface 42, and the upper gear 8 is in meshing connection with the tooth surface 42 of the first transmission member 4. The motor 9 drives the rotating shaft 80 to rotate, the rotating shaft 80 drives the upper gear 8 to rotate, and the upper gear 8 drives the first transmission member 4 to move through the tooth surface 42 of the first transmission member 4.

[0024] As shown in Figure 3As shown, the lower end of the rotating shaft 80 is connected with the output shaft 91 of the motor 9 through the gear pair 10. The output shaft 91 of the motor 9 drives the rotating shaft 80 to rotate through the gear pair 10.

[0025] Finally, it is worth mentioning that the mounting seat 3 is provided with a guide groove 30, and the first transmission member 4 has a guide portion 41 which is slidingly arranged in the guide groove 30. When the motor 9 drives the first transmission member 4 to move, the guide portion 41 of the first transmission member 4 slides in the guide groove 30.
