one end of the first pawl is fixed on the first pawl fixing structure, and the other end of the first pawl is abutted against any tooth groove of the first ratchet wheel;

the first pawl fixing structure is fixedly connected with the pendulum bob through the oscillating bar 3, so that the first pawl fixing structure rotates along with the swinging of the pendulum bob;

the driving device also comprises an energy storage structure in transmission connection with the first ratchet wheel, and the energy storage structure is used for storing mechanical energy generated by rotation of the first ratchet wheel and outputting the stored mechanical energy.

When the equipment that is provided with drive arrangement of this application takes place the action, the pendulum can swing along with this action to it is rotatory to drive first pawl fixed knot structure, because the one end of first pawl is fixed on the first pawl fixed knot structure, the other end supports in any gullet of first ratchet, consequently, when first pawl fixed knot structure takes place rotatoryly, first pawl supports the one end in any gullet of first ratchet and can promote first ratchet and rotate, because energy storage structure is connected with first ratchet transmission, consequently, energy storage structure can save first ratchet pivoted mechanical energy, so that the output provides power. Based on above-mentioned structure, as long as the equipment that is provided with the drive arrangement of this application takes place the action, the mechanical energy in the energy storage structure just can increase to provide power, even be in the environment that can't supply power, this equipment still can rely on the mechanical energy operation work in the energy storage structure.

The energy storage structure can be, but is not limited to, a barrel, an input end 41 of the barrel is in transmission connection with the first ratchet wheel, and an output end 42 of the barrel is connected with the power output device. Wherein the drive connection can be driven by means of a drive gear 44.

In addition, the input end and the output end are both gears, and the spring box further comprises a spring 43; one end and the input fixed connection of clockwork spring, the other end and the output fixed connection of clockwork spring.

To prevent the mechanical energy stored in the spring from being output from the input gear, a third pawl is provided at the input, as the spring is being wound. The rotation direction of the input gear for winding up the spring is expressed as normal rotation, the input gear does not rotate reversely due to the presence of the third pawl, and the mechanical energy in the spring can be output only from the output gear. The fourth pawl also prevents rotation of the output gear in a direction opposite the predetermined rotational direction.

Note that the barrel further includes a torque limiter 47 provided outside the spring. Because the clockwork spring has a certain limit, after the torque limiter is arranged on the outer side of the clockwork spring, when the clockwork spring winds up and exceeds the torque of the torque limiter, the torque limiter slips, the clockwork spring cannot wind up continuously at the moment, and the condition that the clockwork spring is broken is avoided.

When the equipment provided with the driving device acts, the pendulum bob swings along with the driving device, when the pendulum bob swings towards a first direction, the first pawl fixing structure and the second pawl fixing structure rotate along with the pendulum bob in the same direction, and at the moment, the first pawl can push the first ratchet wheel to rotate so as to store mechanical energy generated by the rotation of the first ratchet wheel in the energy storage structure; because the direction that the first pawl pushes the first ratchet wheel is opposite to the direction that the second pawl pushes the second ratchet wheel, when the first pawl pushes the first ratchet wheel, the second pawl slips on the second ratchet wheel, and the second pawl can not push the second ratchet wheel to rotate.

When the pendulum bob swings towards the second direction, the first pawl fixing structure and the second pawl fixing structure rotate along the same direction of the pendulum bob, at the moment, the second pawl pushes the second ratchet wheel to rotate, the first pawl slips on the first ratchet wheel, because the second bevel gear and the second ratchet wheel are arranged in a synchronous transmission manner, when the second ratchet wheel rotates, the second bevel gear is synchronously driven to rotate, and further the third bevel gear meshed with the second bevel gear is driven to rotate, and further the first bevel gear meshed with the third bevel gear rotates along a direction opposite to the rotation direction of the second bevel gear, because the first bevel gear and the first ratchet wheel are arranged in a synchronous transmission manner, the first ratchet wheel can synchronously rotate along with the first bevel gear, and because the rotation directions of the first bevel gear and the second bevel gear are opposite, at the moment, the rotation direction of the first ratchet wheel is still the same as the rotation direction of the first ratchet wheel when the pendulum bob swings towards the first direction, at this time, the mechanical energy rotating in the same direction is still provided for the energy storage structure.

Therefore, no matter the pendulum swings in the first direction or the second direction, the first ratchet wheel provides mechanical energy in the same rotation direction to the energy storage structure, so that the mechanical energy of the pendulum swinging in two directions is stored.
