[0017] Referring to the accompanying drawings, a helmet cylindrical lock with a push-to-lock control includes: a helmet fixing part, a lock tongue and a control part, a power part, a lock body part and a control part.

[0018] The helmet fixing part comprises: a hollow helmet lock column 1-1, the hollow helmet lock column 1-1 is fixed on a lock body 2-1 of the lock body part, and a lock tongue hole 1-2 is arranged on the hollow helmet lock column 1-1.

[0019] When in use, the locked helmet is sleeved on the helmet lock post 1-1 through the locking hole on the helmet.

[0020] The lock tongue and control part include: a lock tongue 3-1, a lock tongue locking rod 3-2, a lock tongue control pin 3-3, a control pull rod 3-4 and a control sleeve 3-5.

[0021] The lock tongue 3-1 is rotatably installed in the hollow helmet lock column 1-1 via a torsion spring 3-11, and the installation position of the lock tongue 3-1 corresponds to the lock tongue hole 1-2 on the hollow helmet lock column 1-1.

[0022] The lock tongue 3-1 is often retracted in the helmet lock column 1-1 under the action of the torsion spring 3-11. When locking, it extends out of the helmet lock column 1-1 through the lock tongue hole 1-2 to lock the helmet on the helmet lock column 1-1.

[0023] The lock tongue locking rod 3-2 is slidably installed in the hollow helmet lock column 1-1 through the lock rod reset spring 3-21, the upper end of the lock tongue locking rod 3-2 corresponds to the lock tongue 3-1, and the lower end of the lock tongue locking rod 3-2 is connected to the power part.

[0024] The lock tongue control pin 3-3 is slidably installed in the hollow helmet lock column 1-1, and the installation position of the lock tongue control pin 3-3 corresponds to the side of the lock tongue 3-1. The lock tongue control pin 3-3 is connected to the control sleeve 3-5 through the control pull rod 3-4, and the control sleeve 3-5 is sleeved on the lower outer circle of the hollow helmet lock column 1-1 through the control sleeve reset spring 3-51.

[0025] When in use, after the locked helmet is sleeved on the helmet lock column 1-1 through the locking hole on the helmet, the user presses the control sleeve 3-5 through the locked helmet to overcome the force of the control sleeve reset spring 3-51, and slides downward along the helmet lock column 1-1. The control sleeve 3-5 drives the lock tongue control pin 3-3 to move downward through the control pull rod 3-4. As the lock tongue control pin 3-3 moves downward, the lock tongue 3-1 is pushed to rotate, and the lock tongue 3-1 is pushed to overcome the force of the torsion spring 3-11 and extend out of the helmet lock column 1-1. The lock tongue 3-1 is pushed and at the same time, the lock tongue locking rod 3-2 is pushed through the upper end inclined surface of the lock tongue locking rod 3-2, and the lock tongue locking rod 3-2 is pushed to move downward to overcome the force of the locking rod reset spring 3-21. When the lock tongue 3-1 is rotated into place, the lock tongue locking rod 3-2 is reversely stuck through the lock tongue 3-1, so that the helmet is locked (as shown in the attached Figure 2 as shown).

[0026] After the locked helmet loses its downward force (the user lets go), the control sleeve 3-5, under the action of the control sleeve reset spring 3-51, drives the lock tongue control pin 3-3 to reset through the control pull rod 3-4 (as shown in the attached Figure 3 as shown).

[0027] In an embodiment of the present invention, the power part includes: a motor 4-1, a pull rod control cam 4-2, and a switch control cam 4-3. The pull rod control cam 4-2 and the switch control cam 4-3 are installed on the output shaft of the motor 4-1. The pull rod control cam 4-2 is arranged in a control groove 3-22 on the lock tongue locking rod 3-2, and the switch control cam 4-3 corresponds to the position of the control switch 5-1.

[0028] The motor 4-1 drives the pull rod control cam 4-2 and the switch control cam 4-3 to rotate, and the pull rod control cam 4-2 drives the lock tongue locking rod 3-2 to move downward through the control slot 3-22 on the lock tongue locking rod 3-2, so that the lock tongue locking rod 3-2 leaves the lock tongue 3-1, and the lock tongue 3-1 rotates and retracts in the helmet lock column 1-1 under the action of the torsion spring 3-11 to achieve unlocking. When the switch control cam 4-3 rotates to the corresponding position, the touch control switch 5-1 is touched, and the touch control switch 5-1 sends a position signal of the lock tongue locking rod 3-2.

[0029] In the embodiment of the present invention, the locking tongue control pin 3-3 is rotatably connected to the control rod 3-4 via the central rotating shaft, so that the locking tongue control pin 3-3 can rotate when pushing the locking tongue 3-1, thereby reducing resistance and improving the flexibility of movement.

[0030] In the embodiment of the present invention, the control sleeve 3-5 is provided with an RFID card reader or an NFC card reader 6. When the card reader 6 recognizes that the chip on the helmet is correct, the control part controls the starting power part to open the lock tongue locking rod 3-2 to the pre-locking posture. Otherwise, the lock tongue locking rod 3-2 is in a non-contact position with the lock tongue 3-1.
