Description

Technical Field

[0001] The present invention relates to the technical field of magnetic fluid devices, and in particular to a wearable legging based on ferromagnetic fluid. Background Art

[0003] Electromagnetic ferrofluid-based energy harvester,Physics Letters A

[0004] Ferrofluid is a colloid formed by the fusion of 0.1-100nm magnetic conductive materials, dispersants and carriers. It has many special functions and is one of the most cutting-edge nanotechnologies today.

[0005] Existing mobile phone charging methods mostly rely on pre-charged solid-state batteries such as power banks. If a person is in an environment where charging is inconvenient, such as when out and about, constantly in motion and using a mobile phone (such as a courier), or in the wild, using clean energy generated by the mechanical movement of the human body can enable low-power devices to be charged anytime and anywhere.

[0006] The human body generates mechanical energy during movement. However, this mechanical motion is low-frequency and subject to randomness and uncertainty. Existing devices using permanent magnets, coils, and containers to magnetize the ferrofluid are all hard solids. Other designs using wearable fabrics for energy conversion have failed to effectively convert the mechanical energy of the legs—the primary site of motion. To address this, we propose a wearable legging based on ferrofluid. Summary of the Invention

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wearable leggings based on ferromagnetic fluid to solve the problem that the permanent magnets, coils and containers used in the magnetized magnetic fluid in the existing devices proposed in the above-mentioned background art are all hard solids, and other designs using wearable fabrics for energy conversion fail to effectively convert the mechanical energy of the legs, the main part of a person's body during exercise.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a wearable leggings based on ferromagnetic fluid, comprising a leggings body and a flexible supercapacitor and rectifier module, wherein the flexible supercapacitor and rectifier module are circuit parts, and have a built-in EHC, which is an energy collection and conversion module composed of a super flexible supercapacitor and a rectifier, for energy collection and conversion, wherein the leggings body comprises two, each of which is wrapped with a binding piece fixed to the left and right legs, a crotch piece is provided between the two binding pieces, and flexible permanent magnetic sheets are fixedly connected to the two outer sides of the leggings body, and the two flexible permanent magnetic sheets are respectively located at Ferrofluid fabric is sewn on the front and back sides of the two binding plates. The permanent magnetic plates on both sides of the legs generate a magnetic field. When the human body walks, runs, or takes steps, the ferrofluid fabric between the legs cuts the magnetic lines of force, thereby generating an induced current. The ferrofluid fabric is electrically connected to the flexible supercapacitor and the rectifier module. The flexible supercapacitor and the rectifier module are electrically connected to the output interface. The output interface outputs the current rectified by the flexible supercapacitor and the rectifier module, and the output interface can be directly connected to a mobile phone or other energy storage device in a pocket.

[0009] The rear side of the binding plate is equipped with a binding mechanism that can bind the legging body to the human leg. The size of the binding mechanism is adjusted according to the different leg shapes of the wearer, so that the binding plate can be fixed on the leg by using the binding mechanism.

[0010] In a preferred embodiment, the shape of the binding piece fits the shape of the human leg, and a connecting piece is installed above the binding piece to connect the binding piece to other parts of the body through the connecting piece to strengthen the fixation of the binding piece to the leg.

[0011] In a preferred embodiment, the connecting piece can fit the shape of the leg, and the connecting piece is fixed to the leg above the binding piece to enhance the firmness of the overall structure when connected to the body, so as to strengthen the fixation of the binding piece to the leg;

[0012] In a preferred embodiment, the connecting piece can fit the shape of the waist and be fixed to the waist above the binding piece to enhance the firmness of the overall structure when connected to the body, so as to strengthen the fixation of the binding piece to the leg;

[0013] In a preferred embodiment, the ferrofluid fabric includes a nylon tube and stretchable conductive fibers. The nylon tube is arranged horizontally and the stretchable conductive fibers are arranged longitudinally and are woven. The nylon tube contains ferromagnetic fluid. When the human body walks, runs, or takes steps, the nylon tube containing the ferromagnetic fluid and the stretchable conductive fibers are driven to swing continuously.

[0014] In a preferred embodiment, the shape of the ferrofluid fabric fits the shape of the front side of the human leg, and the ferrofluid fabric is at the same height as the flexible permanent magnetic sheet. The flexible permanent magnetic sheet can refer to the FlexMag in the prior art. When the two flexible permanent magnetic sheets form a magnetic field, the ferrofluid fabric moves in the magnetic field and cuts the magnetic lines of force vertically, thereby making the efficiency of generating induced current inside the ferrofluid fabric the highest.

[0015] In a preferred embodiment, the two flexible permanent magnetic sheets are at the same height, and the shape of the flexible permanent magnetic sheets fits the shape of the outside of the human leg, so that the permanent magnetic sheets can better fit the outside of the leg without affecting the comfort of the leg.

After the binding plate is placed at a specified position on the leg, the pull rope is used to wrap around the outside of the leg, and then the male buckle and the female buckle are buckled together to fix the binding plate.

[0017] In a preferred embodiment, a number of equally spaced rings are connected to the side edges of the two binding plates, and the rings connected to the side edges of the two binding plates are staggered. Both ends of the draw rope pass through the rings on both sides alternately, thereby achieving multi-point fixation of the binding plates through the rings, thereby achieving a better fixing effect of the binding plates.

[0018] In a preferred embodiment, the binding mechanism includes a belt groove installed on the rear side of the binding plate, a fixing belt is sleeved inside the belt groove, and a number of equally distributed belt rings are connected to the side edges of the two binding plates. The belt rings connected at the side edges of the two binding plates are staggered, and both ends of the fixing belt alternately pass through the belt rings on both sides and are connected with adhesive Velcro. The two sides of the binding plate are fitted together using Velcro, so that the binding plate can be fixed to the leg.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up flexible permanent magnetic sheets and ferrofluid fabrics, compared with the existing technology, the micro-movement of the ferrofluid fabric cuts the magnetic field formed by the flexible permanent magnetic sheets, so that the ferrofluid inside the ferrofluid fabric generates current, thereby realizing the conversion of human mechanical energy into usable electrical energy.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] Magnetic fluids can be used to collect energy from low-frequency random and non-stationary vibrations. There are many types of ferromagnetic fluids. e2 O3 magnetic microparticle fluid.

[0034] Reference Figure 1In this approach, a ferrofluid is placed in a container wrapped with a coil of wire. A permanent magnet is then used to magnetize the ferrofluid from the outside. When external vibrations cause the ferrofluid to slosh in the container, the magnetic flux field relative to the wire coil changes. This change in magnetic flux induces a voltage in the coil, according to Faraday's law of electromagnetic induction.

[0035] Example 2

[0036] As attached Figure 1-6 The wearable leggings based on ferromagnetic fluid shown in the figure include a leggings body 1 and a flexible supercapacitor and rectifier module 4. The flexible supercapacitor and rectifier module 4 is a circuit part with a built-in EHC. The EHC is an energy collection and conversion module composed of a super flexible supercapacitor and a rectifier, which is used for energy collection and conversion. The leggings body 1 includes two, each of which is wrapped with a binding piece 101 fixed to the left and right legs. A crotch piece is provided between the two binding pieces 101. The two outer sides of the leggings body 1 are fixedly connected with flexible permanent magnetic pieces 2. The two flexible permanent magnetic pieces 2 are respectively located on the outer sides of the two binding pieces 101. The binding pieces 101 are Ferrofluid fabric 3 is sewn on the front and back sides, so that the front and back of the human legs are wrapped by the ferrofluid fabric 3. The permanent magnetic sheets 2 on both sides of the legs generate a magnetic field. When the human body walks, runs, or takes steps, the ferrofluid fabric 3 between the legs cuts the magnetic lines of force, thereby generating an induced current. The ferrofluid fabric 3 is electrically connected to the flexible supercapacitor and rectifier module 4, and the flexible supercapacitor and rectifier module 4 are electrically connected to the output interface 5. The output interface is used to output the current rectified by the flexible supercapacitor and rectifier module 4, and the output interface can be directly connected to a mobile phone or other energy storage device in a pocket.

[0037] The rear side of the binding plate 101 is equipped with a binding mechanism that can bind the legging body 1 to the human leg. The size of the binding mechanism is adjusted according to the different leg shapes of the wearer, so that the binding plate 1 can be fixed on the leg using the binding mechanism.

[0038] Specifically, the shape of the binding sheet 101 fits the shape of the human leg. A connecting sheet 102 is installed above the binding sheet 101 to connect the binding sheet 101 to other parts of the body so as to strengthen the fixation of the binding sheet 101 to the leg.

[0039] Furthermore, the connecting piece 102 can fit the shape of the leg and be fixed to the leg above the binding piece to enhance the firmness of the overall structure when connected to the body, so as to strengthen the fixation of the binding piece 102 to the leg. The fixing of the connecting piece 102 can be done by conventional technical means in the prior art, which will not be described in detail here.

[0040] It is worth noting that the ferrofluid fabric 3 includes a nylon tube 301 and a stretchable conductive fiber 302. The nylon tube 301 is arranged in a horizontal direction and the stretchable conductive fiber 302 is arranged in a longitudinal direction and woven. The nylon tube 301 contains a light hydrocarbon carrier liquid-based ferrofluid. e2 When a person walks, runs, or takes steps, the O3 magnetic microparticle fluid drives the nylon tube 301 containing the ferromagnetic fluid and the stretchable conductive fiber 302 to swing continuously.

[0041] In addition, the shape of the ferrofluid fabric 3 fits the shape of the front of the human leg. The ferrofluid fabric 3 is at the same height as the flexible permanent magnetic sheet 2. The flexible permanent magnetic sheet 2 can refer to the Flex Mag in the prior art. When the two flexible permanent magnetic sheets 2 form a magnetic field, the ferrofluid fabric 3 moves in the magnetic field and cuts the magnetic lines of force vertically, thereby making the induced current generated inside the ferrofluid fabric 3 most efficient.

[0042] Furthermore, the two flexible permanent magnetic sheets 2 are at the same height, and the shape of the flexible permanent magnetic sheets 2 fits the shape of the outside of the human leg, so that the permanent magnetic sheets can better fit the outside of the leg without affecting the comfort of the leg.

[0043] It must be said that the binding mechanism includes a rope groove 601 installed on the rear side of the binding plate 101. The interior of the rope groove 601 is provided with a sliding pull rope 602. The two ends of the pull rope 602 are respectively connected with a male buckle 603 and a female buckle 604. The male buckle 603 and the female buckle 604 are buckled together. After placing the binding plate 101 at the designated position on the leg, use the pull rope 602 to wrap around the outside of the leg, and then buckle the male buckle 603 and the female buckle 604 to fix the binding plate 101.

[0044] It is worth noting that a number of equally spaced rings 605 are connected to the side edges of the two binding plates 101. The rings 605 connected to the side edges of the two binding plates 101 are staggered, and both ends of the pull rope 602 alternately pass through the rings 605 on both sides, thereby achieving multi-point fixation of the binding plate 101 through the rings 605, thereby achieving a better fixing effect of the binding plate 101.

[0045] A binding sheet 101 is placed at the position of the human leg, and the binding sheet 101 is fixed by a binding mechanism, and then the connecting sheet 102 is fixed to the leg above the binding sheet 101, so as to strengthen the fixation of the binding sheet and improve its firmness. When the human body wears the overall structure for walking, running, etc., since the position of the flexible permanent magnetic sheet 2 remains unchanged, the flexible permanent magnetic sheets 2 on both sides generate a relatively static magnetic field. At this time, the ferrofluid fabric 3 cuts the magnetic lines of force as the human leg moves. Subsequently, an induced current is generated inside the ferrofluid fabric 3, and the induced current is rectified by the flexible supercapacitor and the rectifier module 4, and rectified into a current that can be directly used, and flows out through the output interface for use.

[0046] When the binding plate 101 is bound by the binding mechanism, the two ends of the drawstring 602 are first pulled out along the rope groove 601 respectively, and then the two ends are alternately passed through the rings 605 on both sides of the binding plate 101, and the rings 605 passed through by the two ends do not overlap, so that the drawstring 602 is continuously wrapped around the leg from top to bottom, and wrapped to the bottom, and the male buckle 603 and female buckle 604 connected at the two ends are used to buckle, so as to fix the binding plate.

The permanent magnetic sheets 2 are respectively located on the outside of the two binding sheets 101. The front side of the binding sheet 101 is sewn with a ferrofluid fabric 3. The permanent magnetic sheets 2 on both sides of the legs generate a magnetic field. When the human body is walking, running, or taking steps, the ferrofluid fabric 3 between the legs cuts the magnetic lines of force, thereby generating an induced current. The ferrofluid fabric 3 is electrically connected to the flexible supercapacitor and rectifier module 4. The flexible supercapacitor and rectifier module 4 are electrically connected to the output interface 5. The output interface is used to output the current rectified by the flexible supercapacitor and rectifier module 4, and the output interface can be directly connected to a mobile phone or other energy storage device in a pocket.

[0049] The rear side of the binding plate 101 is equipped with a binding mechanism that can bind the legging body 1 to the human leg. The size of the binding mechanism is adjusted according to the different leg shapes of the wearer, so that the binding plate 1 can be fixed on the leg using the binding mechanism.

[0050] Specifically, the shape of the binding sheet 101 fits the shape of the human leg. A connecting sheet 102 is installed above the binding sheet 101 to connect the binding sheet 101 to other parts of the body so as to strengthen the fixation of the binding sheet 101 to the leg.

[0051] Furthermore, the connecting piece 102 can fit the shape of the waist and be fixed to the waist above the binding piece 101 to enhance the firmness of the connection between the overall structure and the body, so as to strengthen the fixation between the binding piece 101 and the leg. The connecting piece 102 can be fixed by conventional technical means in the prior art, which will not be described in detail here.

The nylon tube 301 is arranged in a horizontal direction and the stretchable conductive fiber 302 is arranged in a longitudinal direction, and they are woven. The nylon tube 301 contains a nylon tube 301 containing a light hydrocarbon carrier liquid. e2 When a person walks, runs, or takes steps, the O3 magnetic microparticle fluid drives the nylon tube 301 containing the ferromagnetic fluid and the stretchable conductive fiber 302 to swing continuously.

[0053] It is worth noting that the shape of the ferrofluid fabric 3 fits the shape of the front of the human leg. The ferrofluid fabric 3 is at the same height as the flexible permanent magnetic sheet 2. The flexible permanent magnetic sheet 2 can refer to the Flex Mag in the prior art. When the two flexible permanent magnetic sheets 2 form a magnetic field, the ferrofluid fabric 3 moves in the magnetic field and cuts the magnetic lines of force vertically, thereby making the induced current generated inside the ferrofluid fabric 3 most efficient.

[0054] In addition, the two flexible permanent magnetic sheets 2 are at the same height, and the shape of the flexible permanent magnetic sheets 2 fits the shape of the outside of the human leg, so that the permanent magnetic sheets can better fit the outside of the leg without affecting the comfort of the leg.

[0055] It must be said that the binding mechanism includes a belt groove installed on the rear side of the binding plate 101, and a fixing belt 607 is sleeved inside the belt groove. Several equally distributed belt rings 606 are connected to the side edges of the two binding plates 101. The belt rings 606 connected at the side edges of the two binding plates 101 are staggered. The two ends of the fixing belt 606 alternately pass through the belt rings 606 on both sides and are connected with adhesive Velcro. The two sides of the binding plate 101 are fitted together using Velcro, so that the binding plate 101 can be fixed to the leg.

[0056] A binding sheet 101 is placed at the position of the human leg, and the binding sheet 101 is fixed by a binding mechanism, and then the connecting sheet 102 is fixed to the leg above the binding sheet 101, so as to strengthen the fixation of the binding sheet and improve its firmness. When the human body wears the overall structure for walking, running, etc., since the position of the flexible permanent magnetic sheet 2 remains unchanged, the flexible permanent magnetic sheets 2 on both sides generate a relatively static magnetic field. At this time, the ferrofluid fabric 3 cuts the magnetic lines of force as the human leg moves. Subsequently, an induced current is generated inside the ferrofluid fabric 3, and the induced current is rectified by the flexible supercapacitor and the rectifier module 4, rectified into a current that can be directly used, and flows out through the output interface for use.

[0057] When the binding plate 101 is bound by the binding mechanism, the two ends of the fixing belt 607 are first pulled out along the belt groove respectively, and then the two ends are alternately passed through the belt rings 606 on both sides of the binding plate 101, and the belt rings 606 passed through the two ends do not overlap, so that the fixing belt 607 is continuously wrapped around the leg from top to bottom, wrapped to the bottom, and the Velcro connected at the two ends is used to bond them together, so as to fix the binding plate.
