Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of reaction force driving, and in particular relates to a reaction force driving device. Background Art
[0002] Most of the existing drive devices are direct drives, because direct drives can reduce energy loss during the conduction process. Direct drives can certainly reduce energy loss during the transmission process, but the drive device itself also needs to do work, which becomes the main energy loss.
[0003] The existing drive devices currently have the following problems: For example, gravity power generation: a gravity object falls from a high altitude to drive the motor to generate electricity. However, when the gravity object falls to the ground, the gravity object cannot do work and cannot drive the generator to generate electricity. This is because the gravity potential energy is consumed during the falling process of the gravity object, and when the gravity falls to the ground, the gravity potential energy disappears. If we want the gravity object to continue to drive the generator to generate electricity, we must lift the gravity and repeat the process of the gravity object falling. However, the process of lifting the gravity object also consumes energy and cannot do work externally. Therefore, it cannot meet the existing use requirements of the drive device. Summary of the invention
[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a reaction force driving device that can use elastic reaction force to lift the gravity block and keep the gravity block in continuous motion under the condition of increasing power generation.

The reaction type conduction mechanism includes a positioning mechanism, a positive drive mechanism, a negative drive mechanism and a force release mechanism, the positioning mechanism is arranged on the inner wall of the support plate, the positive drive mechanism is arranged at one end of the positioning mechanism, the negative drive mechanism is arranged on the inner wall of the support plate away from the positive drive mechanism, the force release mechanism is arranged on the negative drive mechanism, and the lifting type power generation mechanism includes a top column mechanism and a force guide mechanism, the top column mechanism is arranged on the upper wall of the driving plate, and the force guide mechanism is arranged on the side wall of the positive drive mechanism.
[0006] As a further preferred embodiment of the present invention, the positioning mechanism includes a positioning rod and a positioning frame, the positioning rod is arranged on the inner wall of the end of the support plate away from the height-enhancing seat, and the positioning frame is symmetrically arranged at both ends of the positioning rod; the positive drive mechanism includes a gear shaft, an external gear and an internal gear, the gear shaft is rotatably arranged at the end of the positioning frame away from the positioning rod, the external gear is symmetrically arranged at both ends of the gear shaft, the internal gear is penetrated and arranged at the end of the support plate away from the height-enhancing seat, and the external gear is meshed with the internal gear; the reverse drive mechanism includes a reaction shaft, a spring block, a reset spring and a series plate, the reaction shaft is arranged between the support plates at one end of the height-enhancing seat away from the gear shaft, a plurality of groups of spring blocks are arranged on the outside of the reaction shaft, and the reset spring is arranged on the spring block On the side away from the reaction force axis, the reset spring is inclined, and the series plate is arranged on the side of the reset spring away from the spring block; the force release mechanism includes a unwinding spring, a rope winding wheel, a guide shaft, a guide wheel, a lower pulley, a lifting rope, a gravity block and a isoforce plate, the rope winding wheel is arranged on the outside of the gear shaft, the unwinding spring is arranged between the positioning frame and the rope winding wheel on the outside of the gear shaft, the guide shaft is arranged between the support plates above the reaction force axis, multiple groups of guide wheels are arranged on the outside of the guide shaft, and multiple groups of lower pull wheels are rotatably arranged on the side of the series plate away from the reset spring, the lifting rope is wound between the rope winding wheel, the guide wheel and the lower pulley, the gravity block is arranged at one end of the lifting rope away from the rope winding wheel, and the isoforce plate is arranged between the gravity blocks.
[0007] Preferably, the top column mechanism includes a driving electromagnet and a floating magnet, a plurality of groups of the driving electromagnets are arranged on the upper wall of the driving plate, the floating magnet is arranged on the side of the gravity block away from the pulling rope, and the driving electromagnet and the floating magnet are arranged opposite to each other; the force guiding mechanism includes a conduction frame and a conduction shaft, the conduction frame is arranged on the side of the internal gear away from the support plate, and the conduction shaft is arranged on the side of the conduction frame away from the internal gear.
[0008] When in use, in the initial state, the gravity of the gravity block is greater than the rotational elastic force of the unwinding spring, and the gravity block falls freely, driving the floating magnet to fit with the driving electromagnet. The unwinding spring is set for unwinding. When the generator is driven, the power input end of the generator is connected to the conduction shaft. At this time, the driving electromagnet is energized to generate magnetism, and the driving electromagnet and the floating magnet are set with opposite poles. The driving electromagnet is fixed on the wall of the driving plate and pushes the floating magnet through repulsion. The floating magnet drives the gravity block to rise, and the tension on the unwinding spring is reduced. The unwinding spring rotates and resets to drive the rope wheel to rotate, and the rope wheel rotates to reel in the lifting rope, and the rope wheel drives the external gear through the gear shaft. The outer gear meshes with the inner gear, and the outer gear drives the inner gear to rotate. The inner gear drives the transmission shaft to rotate through the transmission frame, and the transmission shaft drives the power input end of the generator to rotate. The rotor of the generator (usually an electromagnet or a permanent magnet) rotates in the stator (an iron core with a winding), thereby cutting the magnetic flux lines to generate current. When the gravity block rises to the height specified by the operator, the driving electromagnet is powered off and demagnetized, and the floating magnet loses the repulsive force to lift it. The gravity block falls freely, and the gravity block drives the lifting rope to fall off from the outside of the rope wheel. The rope wheel uses the elastic deformation of the unwinding spring to drive the gear shaft to rotate. The unwinding spring tends to be straightened due to the bent winding state, and the gear The shaft drives the inner gear to rotate through the outer gear, and the inner gear transmits the rotation to the transmission shaft through the transmission frame. The transmission shaft transmits the rotational force to the power input end of the generator. The end of the lifting rope away from the gravity block is fixedly connected to the rope winding wheel. When the lifting rope is completely detached from the outer side of the rope winding wheel, the gravity block stops falling. The gravity potential energy generated by the gravity block when falling will cause impact pressure on the reset spring. The reset spring changes from a straight state to a bent state. The greater the bending degree of the reset spring, the greater the reaction capacity it generates. When the reset spring is bent to a certain degree, the reaction force of the reset spring is greater than the falling potential energy of the gravity block, and the reset spring resets and pulls the gravity block. The force block rises, the tension of the pulling rope between the gravity block and the rope winding wheel decreases, the unwinding spring elastically resets to reel in the pulling rope through the rope winding wheel, and the rope winding wheel drives the outer gear to rotate through the gear shaft, and the outer gear drives the conduction frame and the conduction shaft to rotate through the inner gear. After the gravity block reaches the initial height, it performs free fall motion again, thereby driving the generator to work through the forward and reverse rotation of the gear shaft respectively. When the height of the gravity block does not meet the needs of the operator, the driving electromagnet is energized to generate magnetism, and the driving electromagnet pushes the floating magnet through repulsion, and the floating magnet drives the gravity block to reset to the initial height, completing the integrated use of positive gravity and reverse potential energy.
[0009] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a combination of falling gravity and reaction, and through the reaction-type conduction mechanism and the jacking-type power generation mechanism, the positioning mechanism, the positive drive mechanism, the reverse drive mechanism, the force release mechanism, the top column mechanism and the force guide mechanism cooperate with each other to use the falling potential energy and the reset reaction force of the gravity block, so as to avoid the disappearance of the gravity potential energy after the gravity block falls to the ground, thereby failing to conduct the rotational force to the outside for use, and through intermittent control of the driving electromagnet, the repulsive force of the driving electromagnet is used to push the floating magnet to maintain the falling height of the gravity block, thereby improving the efficiency of converting the gravity potential energy into electrical energy to a certain extent, and the reaction-type conduction mechanism generates The gravity potential energy will cause impact pressure on the reset spring, and the reset spring changes from a straight state to a bent state. The greater the bending degree of the reset spring, the greater the reaction capacity it produces. When the reset spring is bent to a certain degree, the reaction force of the reset spring is greater than the falling potential energy of the gravity block. The reset spring resets and pulls the gravity block up, and the tension of the lifting rope between the gravity block and the rope winding wheel is reduced. The unwinding spring elastically resets to reel in the lifting rope through the rope winding wheel, and the rope winding wheel drives the outer gear to rotate through the gear shaft, and the outer gear drives the conduction frame and the conduction shaft to rotate through the inner gear. After the gravity block reaches the initial height, it performs free fall motion again, thereby driving the generator to work through the forward and reverse rotation of the gear shaft.
