It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited.

[0029] An elastic deformation shaking device based on electromagnetic repulsion force is disclosed in an embodiment of this application. The following combines the attached Figures 1 to 4 to explain in detail the elastic deformation shaking device based on electromagnetic repulsion force provided in the embodiment of this application through specific embodiments and their application scenarios.

[0030] Please refer to Figures 1 to 2 An elastic deformation shaking device based on electromagnetic repulsion force is disclosed in an embodiment of this application. The disclosed elastic deformation shaking device based on electromagnetic repulsion force includes a support part 100, a shaking part 200, and an electromagnetic drive assembly 300. Among them, the support part 100 can be arranged on the ground, the shaking part 200 is connected to the support part 100, and the shaking part 200 is located above the support part 100.

[0031] In the embodiment of the present application, the support part 100 includes a plate-shaped base body 110 and support feet 120. Among them, the support feet 120 are arranged on the lower side of the plate-shaped base body 110, so that there is a certain distance between the plate-shaped base body 110 and the ground. The electromagnetic drive assembly 300 includes a bracket 310, a first coil 320 and a second coil 330. Among them, the first coil 320 is arranged on the lower side of the plate-shaped base body 110, and the first coil 320 is located in the middle of the plate-shaped base body 110. The second coil 330 is arranged on the bracket 310. The bracket 310 is supported on the ground, and the second coil 330 is located below the first coil 320. When the electromagnetic drive assembly 300 is powered on, the first coil 320 and the second coil 330 generate a magnetic repulsive force.

[0032] It should be noted that in the embodiment of the present application, the support part 100 and the shaking part 200 can be an integral structure, that is, the support part 100 and the shaking part 200 are integrally connected. The integral connection design makes the connection between the support part 100 and the shaking part 200 more firm, reduces the looseness and wear between components, and thus enhances the structural stability of the self-shaking relaxation device. Exemplarily, the support part 100 and the shaking part 200 can be integrally formed by using a tubular member or a plate-shaped member made of a metal elastic material, and the metal elastic material can be elastic steel.

[0033] Based on the above technical solution, by intermittently powering on the electromagnetic drive assembly 300, the first coil 320 and the second coil 330 generate a periodic magnetic repulsive force. In this way, when the first coil 320 and the second coil 330 generate a magnetic repulsive force, the middle part of the support part 100 can be pushed upward, so that the shaking part 200 swings downward with the support feet 120 as the warping fulcrum. And during the power-off interval, the support part 100 returns to its elastic deformation and falls, so that the shaking part 200 swings upward again with the support feet 120 as the warping fulcrum. In this way, by intermittently powering on the electromagnetic drive assembly 300, the shaking part 200 can be made to shake up and down periodically, so as to simulate the scene of a fetus floating in amniotic fluid in the uterus and a baby in the arms of an adult when standing, giving the user the greatest sense of security and comfort, truly meeting the sense of security in the user's subconscious, so as to achieve a smooth and quiet transition to the user's sleep critical point, reduce the time from waking to falling asleep, that is, promote the user to fall asleep quickly, and at the same time increase the user's deep sleep time.

[0034] Adopting the method of intermittently generating a magnetic repulsive force by the first coil 320 and the second coil 330 to lift the middle part of the support part 100, so that the shaking part 200 warps back and forth with the support feet 120 as the warping fulcrum to achieve shaking. The structure is ingenious and simple, has low requirements for physical space, and is convenient for production and implementation; at the same time, the first coil 320 and the second coil 330 generate a magnetic repulsive force to lift the support part 100. In this process, electrical energy is converted into magnetic energy and then into the kinetic energy of the support part 100, greatly reducing friction loss while avoiding jerks and impacts.

[0035] In some embodiments of the present application, the bracket 310 includes a base 311 and a plurality of first guide posts 312 connecting the base 311. The first guide posts 312 are longitudinally extended. A guide groove is provided on the plate-shaped base body 110. The first guide posts 312 and the guide groove are slidably engaged in the longitudinal direction. Through the sliding engagement between the first guide posts 312 and the guide groove, it is allowed that the plate-shaped base body 110 can only sway in the longitudinal direction, so that the first coil 320 and the second coil 330 always correspond to each other, and the situation of tipping over can be effectively avoided.

[0036] In a further technical solution, a limiting portion 313 is further provided at the top end of the first guide post 312. Exemplarily, the limiting portion 313 is in the form of a barb provided at the top end of the first guide post 312. By limiting the swing of the plate-shaped base body 110 through the limiting portion 313, the situation that the plate-shaped base body 110 longitudinally disengages during the swinging process can be avoided, ensuring the use stability of the elastic deformation shaking device based on electromagnetic repulsion force.

[0037] In the embodiment of the present application, the middle part of the plate-shaped base body 110 is hollowed out to form two cross beams at its edge. When connecting the electromagnetic driving assembly 300 with the plate-shaped base body 110, two first coils 320 can be arranged in the middle of the cross beams, and the base 311 is arranged below the cross beams. The base 311 can be provided with four first guide posts 312 distributed along its circumferential direction. The four first guide posts 312 are respectively arranged on both sides of the cross beams. In this way, the stability of the electromagnetic driving assembly 300 driving the plate-shaped base body 110 to sway can be improved.

[0038] In some embodiments of the present application, the shaking portion 200 includes a first extension section 210. The first extension section 210 is connected to the plate-shaped base body 110. The first extension section 210 is curved and extended in an arc shape away from the plate-shaped base body 110. Exemplarily, the elastic deformation shaking device based on electromagnetic repulsion force can be a chair structure. The user can lie on the first extension section 210 of the shaking portion 200. When the electromagnetic driving assembly 300 is intermittently powered on, the first extension section 210 can warp reciprocally with the support feet as the warping fulcrum to achieve shaking, so as to achieve the function of relaxation and sleep assistance.

[0039] In a further technical solution, the shaking part 200 further includes a second extension section 220. The second extension section 220 is connected to the first extension section 210, and the second extension section 220 is arranged in an arc and extends completely. Moreover, the bending direction of the second extension section 220 is opposite to that of the first extension section 210. Exemplarily, the elastic deformation shaking device based on electromagnetic repulsion force can be a bed structure. A user can lie on the second extension section 220 of the shaking part 200. Exemplarily, when the elastic deformation shaking device based on electromagnetic repulsion force is a bed structure, the elastic deformation shaking device based on electromagnetic repulsion force can further include a carrier plate 400. The carrier plate 400 is supported on the second extension section 220, and a user can lie on the carrier plate 400 to relax and rest.

[0040] In the embodiment of the present application, the electromagnetic driving component 300 further includes a first iron core 341. The first iron core 341 is arranged in the first coil 320. By arranging the first iron core 341, the magnetic field intensity of the magnetic field generated by the first coil 320 can be enhanced, so as to ensure that when the first coil 320 and the second coil 330 are energized, the plate-shaped base body 110 can be jacked up by a sufficient large magnetic repulsion force. At the same time, the existence of the first iron core 341 can enable the first coil 320 to reduce the current required when generating the same magnetic field intensity, thereby reducing the energy consumption.

[0041] Similarly, the electromagnetic driving component 300 further includes a second iron core 342. The second iron core 342 is arranged in the second coil 330. By arranging the second iron core 342, the magnetic field intensity of the magnetic field generated by the second coil 330 can be significantly improved, and the energy consumption can be further reduced.

[0042] In a further technical solution, the electromagnetic driving component 300 further includes an auxiliary mechanism 350. The auxiliary mechanism 350 includes an adjusting nut 351 and a spring 352. The adjusting nut 351 is in screw fit with the base 311. The upper end of the spring 352 abuts against the plate-shaped base body 110, and the lower end of the spring 352 abuts against the adjusting nut 351.

[0043] Based on the above technical solution, when the load borne by the support portion 100 is large, the adjusting nut 351 can be rotated to move it upward. At this time, the spring 352 is compressed, so that a greater elastic acting force can be applied to the support portion 100, thereby playing an auxiliary supporting role for the support portion 100, effectively reducing the load on the first coil 320 and the second coil 330, enabling the entire support portion 100 to bear a greater user weight, and ensuring the safety and stability of the elastic deformation shaking device based on electromagnetic repulsion force. When the load borne by the support portion 100 is small, the magnetic repulsion force generated between the first coil 320 and the second coil 330 can play a main supporting and lifting role. At this time, the adjusting nut 351 can be rotated to move it downward, and the spring 352 extends to a certain extent, thus avoiding elastic fatigue of the spring 352. That is to say, the elastic deformation shaking device based on electromagnetic repulsion force in the embodiment of the present application can selectively intervene in the elastic force of the spring 352 according to the size of the load on the support portion 100, that is, the greater the load, the greater the supporting elastic force of the spring 352 can be adjusted by rotating the adjusting nut 351, and the smaller the load, the smaller the supporting elastic force of the spring 352. Thereby, it can be realized that the first coil 320 and the second coil 330 can meet a larger load with a smaller power, ensuring the service life of the entire elastic deformation shaking device based on electromagnetic repulsion force.

[0044] It can be understood that when the first coil 320 and the second coil 330 are energized, the first coil 320 and the second coil 330 generate a magnetic repulsion force, and the spring 352 has an auxiliary amplifying effect on the magnetic repulsion force between the first coil 320 and the second coil 330. That is to say, the support portion 100 is jacked upward under the superposition of the elastic supporting force of the spring 352 and the magnetic repulsion force. The spring 352 can significantly reduce the load on the first coil 320 and the second coil 330, thereby extending the service life of the entire elastic deformation shaking device based on electromagnetic repulsion force and reducing the power requirement for the electromagnetic drive assembly 300.

[0045] In the embodiment of the present application, please refer to Figure 4 , the electromagnetic drive assembly 300 further includes an upper base. The first coil 320 is fixedly connected to the upper base, and the upper base is fixedly arranged on the lower side of the plate-shaped base body 110. The second coil 330 is fixedly connected to the bracket 310. That is, the upper base and the bracket 310 respectively provide an installation basis for the first coil 320 and the second coil 330.

[0046] In a further technical solution, the electromagnetic drive assembly further includes a second guide post 371 and a limiting member 372. The upper end of the second guide post 371 is fixedly connected to the upper base. The second guide post 371 passes through the first iron core 341 and the second iron core 342. The lower end of the second guide post 371 is slidably fitted to the bracket 310. The limiting member 372 is connected to the lower end of the second guide post 371, and the limiting member 372 is located on the side of the bracket 310 facing away from the upper base to limit the second guide post 371 from sliding out of the bracket 310. Exemplarily, a threaded section is provided at the lower end of the second guide post 371, and the limiting member 372 is screwed to the lower end of the second guide post 371. Based on the guiding action of the second guide post 371, the first coil 320 and the second coil 330 can always face each other and avoid tipping over, thereby improving the stability of the up-and-down shaking of the support portion 100.

[0047] In the embodiment of the present application, the elastic deformation shaking device based on electromagnetic repulsion further includes a controller, and the controller is electrically connected to the electromagnetic drive assembly 300 to control the first coil 320 and the second coil 330 to generate magnetic repulsion when energized.
