The invention aims to solve the problems in the prior art and provide a heel embedded energy collector with simple structure and small volume.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1 to 5: the present embodiment provides a heel embedded energy collector 100 comprising a base plate 5, a pedal 1, a coil 9 and a magnet cartridge housing 8.
Wherein, four springs 3 are fixedly arranged on the bottom surface of the pedal 1, the four springs 3 are respectively positioned at four corners, the top ends of the springs 3 are fixedly connected with the pedal 1, the bottom ends of the springs 3 are fixedly connected with the bottom plate 5, the coil 9 is embedded on the top surface of the bottom plate 5, the bottom plate 5 is provided with a placing groove corresponding to the coil 9, and the coil 9 is fixedly arranged in the placing groove. An upright post 2 and a guide post 14 are inserted into each spring 3, the top end of the upright post 2 is fixedly connected with the bottom surface of the pedal 1, the bottom end of the upright post 2 is fixedly connected with a clamping piece 4, the diameter of the upright post 2 is smaller than the inner diameter of the spring 3, the diameter of the clamping piece 4 is equal to the inner diameter of the spring 3, and the clamping piece 4 can limit the movement of the upright post 2; the bottom end of the guide post 14 is fixedly connected with the bottom plate 5, and a gap is formed between the clamping piece 4 and the guide post 14. The outer wall of the top of the upright post 2 is provided with threads, and the upright post 2 is in threaded connection with the pedal 1.
Two N-pole magnets 12, two S-pole magnets 13 and a cantilever beam 11 are fixedly arranged in the magnet box shell 8, and one end of the cantilever beam 11, which extends out of the magnet box shell 8, is fixedly connected with the bottom plate 5; the bottom plate 5 is provided with a clamping groove corresponding to the cantilever beam 11, one end of the cantilever beam 11 extending out of the magnet box shell 8 is provided with a downward extending part, the extending part is in interference fit with the clamping groove, the magnet box shell 8 is positioned above the coil 9, and an interval is arranged between the magnet box shell 8 and the coil 9. The two N-pole magnets 12 and the two S-pole magnets 13 are arranged in a square array, and any one of the N-pole magnets 12 is adjacent to any one of the S-pole magnets 13. The N-pole magnet 12 and the S-pole magnet 13 form a square magnet array and are clamped in the magnet box shell 8 together with the cantilever beam 11 through interference fit; the cantilever beam 11 is made of 65Mn spring 3 steel.
An additional permanent magnet 10 is further fixedly arranged on the bottom plate 5, and the additional permanent magnet 10 and the clamping groove in the bottom plate 5 are fixedly connected with the bottom plate 5 in an interference fit mode. An interval is arranged between the additional permanent magnet 10 and the magnet box shell 8, the additional permanent magnet 10 is close to the other end of the cantilever beam 11, and the additional permanent magnet 10 and the pressing block 6 are respectively positioned at two sides of the cantilever beam 11; when the interval between the magnet box case 8 and the additional permanent magnet 10 is minimized, the additional permanent magnet 10 is repelled from the magnet in the magnet box case 8 that is closest to the additional permanent magnet 10.
The working principle of the heel embedded energy collector 100 of the present embodiment is as follows: when a human body acts, a foot applies force to the pedal 1 to drive the press block 6 to move downwards, the press block 6 pushes the convex block, the magnet box shell 8 and the square magnet array to move, in the process, the cantilever beam 11 is stressed to generate bending deformation, the acting force of the press block 6 on the magnet box shell 8 plays a leading role, although the additional permanent magnet 10 and the N-pole magnet 12 in the magnet box shell 8 have mutual repulsive force, the repulsive force is far smaller than the acting force of the press block 6 on the magnet box shell 8.
When the foot is lifted, the pedal 1 bounces upwards under the action of the spring 3, the pressing block 6 moves upwards along with the pedal 1, the pressing block 6 is in threshing contact with the bump, the cantilever beam 11 is restored to the original state by the self restoration property and the repulsive force between the additional permanent magnet 10 and the N-pole magnet 12 in the magnet box shell 8, at the moment, the repulsive force of the additional permanent magnet 10 borne by the square magnet array dominates the movement of the magnet array, so that the magnet array is accelerated to move to the balance position, and the electric quantity generated in the process is higher than that generated when the additional permanent magnet 10 is not added (the restoration speed is increased by a certain amount). The magnet box housing 8 and the square magnet array generate high-frequency vibration at the equilibrium position due to the effect of inertia, and conversion from low-frequency input to high-frequency vibration is achieved. In the whole process, the magnet array and the coil 9 array always have relative motion, so that the magnetic flux in the coil 9 changes, and induced electromotive force can be generated in the coil 9 according to a Faraday's law of electromagnetic induction. An additional permanent magnet 10 is embedded in the bottom plate 5, and in the recovery process of the cantilever beam 11, when the cantilever beam 11 crosses the equilibrium state and approaches the additional permanent magnet, the action force of a magnetic field is applied, so that the amplitude of the cantilever beam 11 is further increased, and the vibration frequency of the cantilever beam 11 is further adjusted.
It should be noted that the electric energy utilized by the heel embedded energy collector 100 of the present embodiment is mainly concentrated on: firstly, the electric quantity generated in the pressing-down process of the pressure block 6 (the time of the pressing-down process is very short, the speed is high, and the generated electric quantity is large); secondly, the electric quantity generated in the process of restoring the magnet array to the balance position for the first time is larger due to the existence of the repulsive force of the additional permanent magnet 10. Because the vibration of the spring 3 steel is attenuated relatively fast, the electric quantity generated in the vibration process of the spring 3 steel is not enough to be utilized, and the voltage curve mainly only plays a role in representing the vibration attenuation. The coil 9 needs to be electrically connected to the wearable electronic device or to a rechargeable battery to complete the collection of electrical energy.
