The box 1 further comprises an output shaft 2 penetrating through the inside and the outside of the box 1 and a driving assembly 3 arranged in the box 1, one end of the output shaft 2 penetrating out of the box 1 is connected with power generation equipment, and the power generation equipment is driven to generate power by outputting unidirectional rotating rotary mechanical energy. The driving assembly 3 comprises a first unidirectional driving piece 31 and a second unidirectional driving piece 32 which are arranged front and back, the first unidirectional driving piece 31 and the second unidirectional driving piece 32 are fixedly arranged on the output shaft 2, the input part 11 is connected with the first unidirectional driving piece 31, and the input part 11 drives the first unidirectional driving piece 31 to rotate when in reciprocating movement, so that the output shaft 2 is controlled to rotate in a single direction. One side of the driving assembly 3 is provided with a steering assembly 4, which is connected with the first unidirectional driving piece and the second unidirectional driving piece, and when the first unidirectional driving piece 31 rotates forward and backward, the second unidirectional driving piece 3 is respectively rotated and idled through the steering assembly 4.

In a first embodiment of the present utility model, as shown in fig. 1, 2 and 5, the input member 11 is a rack 12 penetrating through the inside and outside of the case 1, one end of the rack 12 is connected to the external kinetic energy, and two ends of the rack 12 are respectively provided with a stopper 13 for fixing the moving distance of the rack 12. A return spring 14 for damping shock and realizing automatic return of the rack 12 is arranged at one end of the rack 12 connected with external kinetic energy, and the return spring 14 is arranged between the outer wall of the box body 1 and the limiting block 13.

The first unidirectional driving member 31 includes a first gear 33 and a first unidirectional bearing 35 fixedly sleeved on the axis of the first gear 33, and the first unidirectional bearing 35 is in interference fit connection with the output shaft 2; the second unidirectional driving member 32 includes a second gear 34 and a second unidirectional bearing 36 fixedly sleeved on the axis of the second gear 34, where the second unidirectional bearing 36 is in interference fit with the output shaft 2. The rack gear 12 is engaged with the first gear 33, so that the first gear 33 is driven to rotate when the rack gear 12 reciprocates. The number of teeth and the modulus of the first gear 33 and the second gear 34 are the same, the first unidirectional bearing 35 and the second unidirectional bearing 36 are unidirectional bearings with the same steering direction, the first gear 33 is fixedly connected with the first unidirectional bearing 35, and the second gear 34 is fixedly connected with the second unidirectional bearing 36. The steering assembly 4 comprises a first transition gear 41 and a second transition gear 42 with the same tooth number and modulus, an upper rotating shaft 15 and a lower rotating shaft 16 are vertically and fixedly arranged on one side in the box body 1, the first transition gear 41 is movably inserted on the upper rotating shaft 15, the second transition gear 42 is movably inserted on the lower rotating shaft 16, and the first transition gear 41 and the second transition gear 42 are meshed. The first gear 33 is engaged with the first transition gear 41, and the second gear 34 is engaged with the second transition gear 42.

The operation of the first embodiment of the mechanism is as follows: when the rack 12 is affected by the external kinetic energy pressure, it generates downward displacement, and drives the first gear 33 to rotate left, and then drives the first transition gear 41 to rotate in the opposite direction, the first transition gear 41 is meshed with the second transition gear 42, and drives the second transition gear 42 to rotate in the same direction as the first gear 33, and the second transition gear 42 is meshed with the second gear 34, and drives the second gear 34 to rotate in the opposite direction to the first gear 33. Since the first one-way bearing 35 is provided between the first gear 33 and the output shaft 2, the first gear 33 slides relatively to the output shaft 2 at this time, and the idle rotation does not output rotation action, and does not generate obstruction action. In contrast, because the second gear 34 and the first gear 33 rotate in opposite directions, the output shaft 2 is driven to rotate in a right-hand direction under the action of the second unidirectional bearing 36, so that the output shaft 2 drives the power generation equipment to perform work and power generation.

When the rack 12 loses the influence of external kinetic energy pressure, the rack 12 is reset upwards under the action of the reset spring 14. The rack 12 drives the first gear 33 to rotate in a right-hand manner in the resetting process, and drives the output shaft 2 to rotate in a right-hand manner under the action of the first one-way bearing 35, so that the output shaft 2 drives the power generation equipment to do work and generate power. At this time, the first gear 33 drives the second gear 34 to rotate in a left-hand direction opposite to the first gear 33 through the first transition gear 41 and the second transition gear 42, and the second gear 34 slides relatively to the output shaft 2 under the action of the second unidirectional bearing 36, and the idle rotation of the second gear does not output rotation action, and does not generate blocking action.

The present utility model also provides a second embodiment, as shown in fig. 3-5, wherein the input member 11 is an eccentric mass 17 fixedly disposed on one side of the first unidirectional driving member 31.

The first unidirectional driving member 31 includes a first gear 33 and a first unidirectional bearing 35 fixedly sleeved on the axis of the first gear 33, and the first unidirectional bearing 35 is in interference fit connection with the output shaft 2; the second unidirectional driving member 32 includes a second gear 34 and a second unidirectional bearing 36 fixedly sleeved on the axis of the second gear 34, where the second unidirectional bearing 36 is in interference fit with the output shaft 2. The eccentric block 17 is fixedly arranged at one side of the first gear 33, and can swing reciprocally in the case when the eccentric block 17 is affected by external vibration, thereby driving the first gear 33 to rotate. The number of teeth and the modulus of the first gear 33 and the second gear 34 are the same, the first unidirectional bearing 35 and the second unidirectional bearing 36 are unidirectional bearings with the same steering direction, the first gear 33 is fixedly connected with the first unidirectional bearing 35, and the second gear 34 is fixedly connected with the second unidirectional bearing 36. The steering assembly 4 comprises a first transition gear 41 and a second transition gear 42 with the same tooth number and modulus, an upper rotating shaft 15 and a lower rotating shaft 16 are vertically and fixedly arranged on one side in the box body 1, the first transition gear 41 is movably inserted on the upper rotating shaft 15, the second transition gear 42 is movably inserted on the lower rotating shaft 16, and the first transition gear 41 and the second transition gear 42 are meshed. The first gear 33 is engaged with the first transition gear 41, and the second gear 34 is engaged with the second transition gear 42.

The second embodiment of the mechanism operates as follows: when the eccentric block 17 is influenced by vibration energy, left and right swinging is generated; when the eccentric block 17 swings leftwards, it drives the first gear 33 to rotate leftwards, and then drives the first transition gear 41 to rotate in the opposite direction, the first transition gear 41 is meshed with the second transition gear 42, drives the second transition gear 42 to rotate in the same direction as the first gear 33, and the second transition gear 42 is meshed with the second gear 34, and drives the second gear 34 to rotate in the opposite direction to the first gear 33. Since the first one-way bearing 35 is provided between the first gear 33 and the output shaft 2, the first gear 33 slides relatively to the output shaft 2 at this time, and the idle rotation does not output rotation action, and does not generate obstruction action. In contrast, because the second gear 34 and the first gear 33 rotate in opposite directions, the output shaft 2 is driven to rotate in a right-hand direction under the action of the second unidirectional bearing 36, so that the output shaft 2 drives the power generation equipment to perform work and power generation.

When the eccentric block 17 swings rightwards, the eccentric block drives the first gear 33 to rotate rightwards, and the output shaft 2 is driven to rotate rightwards under the action of the first one-way bearing 35, so that the output shaft 2 drives the power generation equipment to do work and generate power. At this time, the first gear 33 drives the second gear 34 to rotate in a left-hand direction opposite to the first gear 33 through the first transition gear 41 and the second transition gear 42, and the second gear 34 slides relatively to the output shaft 2 under the action of the second unidirectional bearing 36, and the idle rotation of the second gear does not output rotation action, and does not generate blocking action.

The utility model provides a mechanism for converting external kinetic energy into rotary mechanical energy, wherein a first unidirectional bearing 35 and a second unidirectional bearing 36 are fixedly arranged on a first gear 33 and a second gear 34 with the same tooth number modulus and are arranged on the same output shaft 2 in the same rotation direction; the first gear 33 acts on the second gear 34 through the first transition gear 41 and the second transition gear 42, so that the second gear 34 always rotates in the opposite direction to the first gear 33 but at the same angular velocity, and when the input component 11 drives the first gear 33 to rotate in any direction, the output shaft 2 always keeps the same rotation acting state, and bidirectional displacement of swing or vibration is used for realizing bidirectional acting, thereby reducing the waste of vibration energy and greatly improving the energy conversion efficiency. The unidirectional bearing is used for replacing the traditional ratchet and pawl mechanism and is matched with the gear transmission structure to operate, so that the waste of gear clearances is reduced to the minimum, and therefore, the swing and vibration energy with smaller amplitude can be collected and captured. The setting mode has the advantages of simple structure and few parts, further reduces the failure rate of equipment in operation, and ensures that the equipment is more rapid and convenient in installation and maintenance.
