Description

Technical Field

[0001] This application relates to the field of smart wearable technologies, and particularly to a wearable device and a system for the wearable device. Background Art

[0002] A wearable device is a portable device that is directly worn on the body or integrated into the user's clothing or accessories. A wearable device is not just a hardware device, but rather achieves powerful functions through software support, data interaction, and cloud interaction. Wearable devices will bring great changes to our lives and perceptions.

[0003] A wearable device can carry a device that implements certain functions on a wearable carrier, so as to achieve the intended function through the close contact between the functional part and the body. Most current wearable devices do not contain a controllable moving mechanism. The contact between the functional part and the body is achieved through direct wearing. This limits the use of many functions and the wearing is not comfortable enough.

[0004] Moreover, in many cases, the functional part of the carried device only needs, or should only have, a short-term controllable contact with the target part of the body, and can be stored in a more convenient wearing position usually. In other cases, the target part to be measured cannot be adhered to by the wearable for a long time. To achieve such a goal, a controllable moving mechanism is essential. Summary of the Invention

Detailed implementation mode

[0096] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. Various details of the embodiments of the present application are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, descriptions of well - known functions and structures are omitted in the following description.

[0097] The present application provides a wearable device, and the wearable device includes:

[0098] A displaceable component;

[0099] A functional component located on the displaceable component and moved by the displaceable component;

[0100] The functional component may also be located at one end of the displaceable component.

[0101] A control component that controls the displacement of the displaceable component.

[0102] The displaceable component can move the functional component in a direction away from or closer to the target part.

[0103] The purpose of the movement of the displacement component is to achieve the controllable movement of the functional component between the wearable carrier and the target body position, or to deploy certain structures. For example, when the wearable device is carried on the neck, it is used to monitor the vital signs of the elderly and patients for a long time, analyze the situation in case of emergencies, and provide rescue. For example, when military personnel or high - risk operation personnel are injured and lose the ability to self - rescue, the wearable device can detect and analyze the situation and then carry out emergency treatment (remote diagnosis, communication, first - aid medication, etc.).

[0104] The control component can be a power source, a mechanical device, a power device, etc., and the control component can provide electrical energy, mechanical push / pull force, driving force, etc. for the movable component.

[0105] For the wearable device provided in this application, when it is necessary to make contact with a target position, the control component is used to control the movement of the displaceable component. When the target position is reached, the functional component can make controllable contact with the target part. When the contact ends, the control component controls the displaceable component to move, so as to return to its original position, and further achieve diversified or long-distance controllable movement of the device.

[0106] In this application, the displacement of the displaceable component is caused by the deformation of the electroactive polymer or shape memory material included in the displaceable component.

[0107] In this application, the displaceable component is composed of an electroactive polymer or a shape memory material.

[0108] In this application, the form of the displaceable component is selected from at least one of the following: linear structure, sheet structure, tube structure, and foldable frame structure, three-dimensional network structure, three-dimensional multi-tube array structure, three-dimensional multi-fold structure composed of linear structure, sheet structure or tube structure;

[0114] In this application, the displaceable component includes a multi-torsion spring series framework. The multi-torsion spring series framework includes two or more torsion springs. The torsion springs are connected by a rigid linear structure. The torsion springs and the rigid linear structure are composed of a shape memory material.

[0115] The number of the torsion springs can be 1, 2, 3, 4, 5 or more, and the number of the torsion springs can be determined according to actual needs.

[0116] In a specific embodiment, the displaceable component may also be a single helical spring.

[0117] In the present application, the electroactive polymer is at least one selected from silicone resin, acrylic resin, and polyurethane.

[0118] The electroactive polymer may be a silicone resin material CF1921286.

[0119] The electroactive polymer may be an acrylic resin material VHB4910.

[0120] The electroactive polymer may be polyurethane, a shape memory polyurethane (SMPU) polymerized from three monomer raw materials of polytetramethylene glycol (PTMG), 4,4-diphenylmethane diisocyanate (MDI), and a chain extender.

[0121] The electroactive polymer may be silicone resin and acrylic resin.

[0122] The electroactive polymer may be silicone resin and polyurethane.

[0123] The electroactive polymer may be acrylic resin and polyurethane.

[0124] In the present application, the shape memory material is a metal-based memory material or a non-metal-based memory material.

[0125] The shape memory material can itself be made into a mechanism with controllable deformation movement between a normally closed state and an activated and expanded state. Many shape memory materials respond to temperature, ultraviolet light, and electric field stimuli, but ultimately can be converted to electric control.

[0126] In the present application, the metal-based memory material is a nickel-titanium alloy. Nickel-titanium alloy is a shape memory alloy, and a shape memory alloy is a special alloy that can automatically restore its plastic deformation to the original shape at a certain specific temperature and has good plasticity. In addition, memory metal materials can be deformed by attaching a heat source for heating, and some can also be deformed by self-electrifying heating. The elongation rate of nickel-titanium alloy is more than 20%, and the fatigue life reaches 1×10 7 , and the damping characteristic is 10 times higher than that of ordinary springs. Its corrosion resistance is better than the best current medical stainless steel. Therefore, it can meet the application requirements of various engineering and medical fields and is a very excellent functional material. In addition to the unique shape memory function, memory alloy also has excellent characteristics such as wear resistance, corrosion resistance, high damping, and superelasticity.

[0127] The specific proportion of the nickel-titanium alloy: the proportion of nickel is between 50.8% and 55%, and the rest is titanium.

[0128] The same nickel-titanium alloy can be made into single-way memory or two-way memory.

[0129] In this application, the non-metallic memory material is selected from at least one of copolyesters and copolyamides.

[0130] In this application, the copolyamide-based memory materials are polynorbornene, polyurethane, high-trans polyisoprene, and styrene-butadiene copolymer. (Japan already has 4 industrial production technologies for SMPs, namely shape memory polynorbornene, polyurethane, high-trans polyisoprene, and styrene-butadiene copolymer. Other varieties also include fluororesins, polycaprolactone, polyamides, etc.)

[0131] In this application, a conductive substance is mixed into the shape memory material. The conductive substance is selected from at least one of carbon black, metal powder, or conductive polymer. Mixing a conductive substance into the shape memory material can make the displaceable component energized, that is, the displaceable component can deform by self-heating.

[0132] In this application, the displaceable component has a single-layer or multi-layer composite sheet structure. At least one layer of the composite sheet structure is composed of an electroactive polymer or a shape memory material.

[0133] When at least one layer of the composite sheet structure is composed of the electroactive polymer, when the displaceable component is subjected to an electrical stimulus, the composite sheet undergoes deformation (elongation or contraction or twisting), so that the displaceable component drives the functional component to displace.

[0134] The shape memory material can itself be made into a mechanism with controllable deformation movement between a generally folded state and an excited unfolded state. (Compared with electroactive materials, the deformation characteristic of shape memory materials is that they often change back and forth between two forms.) Many shape memory materials respond to temperature, ultraviolet light, and electric field stimuli, but ultimately can be converted to electrical control.

[0135] In this application, the electroactive polymer or shape memory material can be directionally elongated / contracted or deformed after being stimulated by the outside world.

[0136] In this application, an isolation film is provided between adjacent composite sheet structures. The isolation film is an insulating and heat-insulating material. The isolation film isolates the conduction or heat conduction between adjacent composite material units, thereby protecting the movable component and extending its lifespan.

[0137] In this application, the directional elongation / shrinkage rate of each layer of the composite sheet structure gradually increases in the arranged order after the same external stimulus. When the displaceable component is subjected to an electrical stimulus, different degrees of deformation occur successively in each layer of the composite sheet, so that the displaceable component drives the functional component to perform a controllable displacement.

[0138] In this application, the displaceable component includes a three-layer composite structure, and the three-layer composite structure includes a first outer layer, a core layer, and a second outer layer arranged in sequence; both the first outer layer and the second outer layer include two or more strips arranged side by side; a conduit extending along the core layer is provided in the core layer, and the extending direction of the strips is the same as the extending direction of the conduit.

[0139] The first outer layer, the core layer, and the second outer layer are all composed of electroactive polymers or shape memory materials, and the electroactive polymers or shape memory materials of each strip in the first outer layer and the second outer layer and the core layer are independent of each other under external stimuli.

[0140] The electroactive polymers or shape memory materials constituting the first outer layer, the core layer, and the second outer layer are all directionally elongated / shrunk after being subjected to external stimuli, and the direction of directional elongation / shrinkage is the same.

[0141] The simultaneous shrinkage of the strips in the first outer layer (upper layer) causes the displaceable component to lift or curl upward; the simultaneous shrinkage of each strip in the second outer layer (lower layer) causes the displaceable component to press or curl downward; the simultaneous shrinkage of the leftmost strips in the first outer layer and the second outer layer (upper and lower layers) causes the displaceable component to bend to the left, and the simultaneous shrinkage of the rightmost strips in the first outer layer and the second outer layer (upper and lower layers) causes the displaceable component to bend to the right. Combinatorial coordination enables bending movement in all directions in space.

[0142] In this application, the electroactive polymers constituting the first outer layer, the core layer, and the second outer layer are at least one of silicone resin or acrylic resin. The silicone resin may be a silicone resin material CF1921286, and the acrylic resin may be an acrylic resin VHB4910.

[0143] The materials constituting the first outer layer and the second outer layer may be the same or different.

[0144] In this application, the shape memory material constituting the first outer layer, the core layer, and the second outer layer is shape memory polyurethane. The polyurethane is a polyurethane (SMPU) polymerized from three monomer raw materials of polytetramethylene glycol (PTMG), 4,4-diphenylmethane diisocyanate (MDI), and a chain extender.

[0145] In the present application, the displaceable component includes a cylindrical displacement unit, and the displacement unit sequentially includes an inner tube, a longitudinally extending layer, an inner spiral annular layer, an outer spiral annular layer, and a transverse annular layer from the inside to the outside.

[0146] The longitudinally extending layer includes a plurality of first extending strip blocks extending parallel to the inner tube, and the plurality of first extending strip blocks are uniformly distributed around the inner tube.

[0147] The inner spiral annular layer includes a plurality of second extending strip blocks coiled in a spiral shape outside the longitudinally extending layer, and the plurality of second extending strip blocks are uniformly distributed around the longitudinally extending layer.

[0148] The outer spiral annular layer includes a plurality of third extending strip blocks coiled in a spiral shape outside the first spiral annular layer, and the plurality of third extending strip blocks are uniformly distributed around the second spiral annular layer; the spiral direction of the second extending strip block is opposite to the spiral direction of the third extending strip block.

[0149] The transverse annular layer is a cylindrical shape composed of a plurality of parallel circular rings, and the transverse annular layer wraps outside the outer spiral annular layer.

[0150] The longitudinally extending layer, the inner spiral annular layer, the outer spiral annular layer, and the transverse annular layer are independent of each other and do not affect each other during operation. The deformation of the longitudinally extending layer can affect the length of the displacement component, the deformation of the transverse annular layer can affect the diameter of the displacement component, and the deformation of the inner spiral annular layer and the outer spiral annular layer can affect the twisting of the displacement component. When the inner spiral annular layer and the outer spiral annular layer deform separately, the twisting directions of the displacement component are opposite.
