Description

Technical Field

[0001] This application relates to the field of printed circuit boards, and more particularly to a wearable device. Background Technology

[0002] Frequent clothing changes due to large temperature differences between day and night bring several drawbacks. First, frequent clothing changes increase the frequency and duration of changing clothes, thus increasing the difficulty of cleaning and maintenance. Second, frequent clothing changes may cause discomfort, leading to skin sensitivity, allergic reactions, or even fever. Furthermore, frequent clothing changes may increase the probability of clothing damage and shorten its lifespan. Finally, frequent clothing changes also easily lead to the hassle of organizing and storing clothes, increasing personal stress.

[0003] In the cold winter, due to the low temperatures, workers need to wear heavy clothing for production and maintenance work. This not only affects their health but may also lead to decreased work efficiency. First, wearing heavy clothing slows down their movements, thus impacting their work efficiency. Second, excessively thick clothing increases body heat loss, making them more prone to fatigue and affecting work quality. Furthermore, wearing clothing can increase the risk of limb injuries, as thick clothing may restrict the movement of gloves or other protective gear, failing to effectively protect the worker's limbs. Finally, excessively thick clothing can restrict vision, potentially hindering their work.

[0004] Therefore, there is an urgent need to provide a smart device that can flexibly adjust the temperature inside and outside clothing. Summary of the Invention

It should be noted that, unless otherwise specified, the features in the embodiments of this application can be combined with each other.

[0033] The following description sets forth numerous specific details to provide a thorough understanding of the embodiments of the present invention. The described embodiments are only a part of, and not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the embodiments of the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the invention pertain. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of the invention.

[0035] Please see Figure 1 and Figure 2 This application provides a wearable device 100. The wearable device 100 can be woven with textiles to form clothing. When the wearable device 100 is made into clothing, the inner side of the wearable device 100 is close to the user's skin or body, and the outer side of the wearable device 100 faces the external environment of the clothing. The wearable device 100 includes a circuit board 1 and a first component 21. The circuit board 1 includes a first magnetic unit 121. The first component 21 includes a first support structure 201, a first air blowing device 211, a first movable opening 212, and a first magnetic control unit 213. The first support structure 201 has a first cavity 202. The first movable opening 212 is disposed on the top of the first support structure 201. The first air blowing device 211 is located in the first cavity 202. The first magnetic control unit 213 is disposed in the first support structure 201.

[0036] The materials of circuit board 1 include, but are not limited to, polyimide (PI), liquid crystal polymer (LCP), polytetrafluoroethylene (PTFE), and polydimethylsiloxane.

[0037] In some embodiments, the opening degree of the first movable opening 212 can be adjusted according to actual needs. For example, the first movable opening 212 can be completely closed, partially open, or fully open. Please refer to [link to relevant documentation].

When viewed from the first movable opening 212 toward the interior of the first component 21, the first air blowing device 211 can be observed, that is, the first movable opening 212 and the first air blowing device 211 are arranged opposite to each other.

[0038] In some embodiments, the first air blowing device 211 can rotate clockwise and counterclockwise as needed, and the rotation speed is adjustable. When the first air blowing device 211 rotates clockwise, it blows air in a direction away from the first movable opening 212, thereby reducing the temperature on the side where the first air blowing device 211 is located. When the first air blowing device 211 rotates counterclockwise, it blows air in a direction towards the first movable opening 212, causing the air provided by the first air blowing device 211 to flow towards the first movable opening 212, thereby reducing the temperature on the side where the first movable opening 212 is located. In some embodiments, the first air blowing device 211 can also be a bladeless air blowing device.

[0039] In some implementations, please refer to Figure 1 and Figure 2 The first component 21 also includes a first driving chip 214, and the circuit board 1 also includes a second magnetic unit 122. The first magnetic control unit 213 is located between the first magnetic unit 121 and the second magnetic unit 122. The first driving chip 214 is used to control the first magnetic unit 121 and / or control the second magnetic unit 122 to attract the first magnetic control unit 213 so as to drive the first component 21 to move toward the first magnetic unit 121 or toward the second magnetic unit 122.

[0040] In some implementations, please refer to Figure 2 The first component 21 includes two first magnetic control units 213, which are located on opposite sides of the first cavity 202. The first driving chip 214 and one of the first magnetic control units 213 are located on the same side of the first cavity 202.

[0041] In some embodiments, the first magnetocontrol unit 213 is composed of a magnetic material capable of generating a magnetic field, including but not limited to magnets, energized coils, etc.

[0042] In some embodiments, the first magnetocontrol unit 213 has a six-faced, cube-shaped structure. Each of five of the faces of the first magnetocontrol unit 213 has an energized coil. See also...

The first magnetic control unit 213 includes a first energized coil 1211, a second energized coil 1212, a third energized coil 1213, a fourth energized coil 1214, and a fifth energized coil 1215. The first energized coil 1211 and the second energized coil 1212 are positioned opposite each other, the third energized coil 1213 and the fourth energized coil 1214 are positioned opposite each other, and the fifth energized coil 1215 is located on the inner surface of the first magnetic control unit 213 facing away from the first driving chip 214. The first driving chip 214 controls the magnetic field changes of the energized coils within the first magnetic control unit 213.

[0043] In some implementations, please refer to Figure 5 and Figure 6 The energized coils of the first magnetocontrol unit 213 can also have different arrangements, and its unfolded diagram can be shown below.

Figure 6 In the unfolded diagram shown, the third energized coil 1213, the first energized coil 1211, the fourth energized coil 1214, and the second energized coil 1212 are located in the same column, and the fifth energized coil 1215 is located to the right of the first energized coil 1211.

[0044] In some embodiments, the first magnetic unit 121 and the second magnetic unit 122 are composed of magnetic materials capable of generating a magnetic field, including but not limited to magnets, energized coils, etc.

[0045] In some implementations, please refer to Figure 2 The first component 21 also includes a second temperature sensor 216, which is located at opposite ends of the first cavity 202 along with the first driving chip 214. The second temperature sensor 216 can detect the temperature inside and on the inner side of the wearable device 100.

[0046] In some implementations, please refer to Figure 2 The first component 21 also includes a first resistor 217 and a first heat dissipation hole 218. The first driver chip 214 drives the first resistor 217 to work. The heat generated by the first resistor 217 after it works is transferred to the surroundings through the first heat dissipation hole 218. The material of the first resistor 217 includes metals such as copper, nickel, phosphorus, aluminum, silicon, and platinum.

[0047] In some implementations, please refer to Figure 2The first component 21 also includes two opposing first sidewall openings 219, which provide openings and channels for air inside the first component 21 to communicate with air outside.

[0048] In some implementations, please refer to Figure 2 The first component 21 has a symmetrical structure, with the first air blowing device 211 at the bottom of the first component 21 and the first movable opening 212 at the top of the first component 21 facing each other. A first magnetic control unit 213, a first resistor 217, and a first heat dissipation hole 218 are symmetrically arranged at opposite ends of the first component 21. A second temperature sensor 216 and a first driving chip 214 are symmetrically arranged at opposite ends of the first component 21. Two first magnetic control units 213 are symmetrically arranged at opposite ends of the first component 21. The two first sidewall openings 219 of the first component 21 are also symmetrically arranged. This symmetrical structure helps to balance the forces when the first component 21 is suspended from the circuit board 1 by elastic wires, and also allows for uniform airflow inside and outside the first component 21 through the first sidewall openings 219 on both sides.

[0049] In some implementations, please refer to Figure 1 The circuit board 1 has a first cavity 251, a first opening 131 and a second opening 132. The first opening 131 and the second opening 132 are connected to the first cavity 251, and the first component 21 is suspended inside the first cavity 251.

[0050] In some implementations, please refer to Figure 1 The circuit board 1 includes a first part 141, a second part 142, a third part 143, and a fourth part 144. The first part 141 and the second part 142 are separated by a first opening 131, and the third part 143 and the fourth part 144 are separated by a second opening 132. One end of the first component 21 is connected to the first part 141 and the third part 143 via a first elastic wire 2151, and the other end of the first component 21 is connected to the second part 142 and the fourth part 144 via a second elastic wire 2152.

[0051] In some embodiments, the first component 21 and the circuit board 1 further include solder pads, and the first flexible wire 2151 is connected at both ends to the solder pads to electrically connect the first component 21 and the circuit board 1.

[0052] The side containing the first opening 131 is the outer side of the wearable device 100, and the side containing the second opening 132 is the inner side of the wearable device 100. The first opening 131 and the second opening 132 provide channels for air circulation between the inside and outside of the wearable device 100. The first component 21 is electrically connected to the circuit board 1 through the first elastic wire 2151 and the second elastic wire 2152. Since the first elastic wire 2151 and the second elastic wire 2152 are elastic, they can provide support for the first component 21 to be suspended in the circuit board 1, and when the first component 21 is displaced, the first elastic wire 2151 and the second elastic wire 2152 will not hinder the movement of the first component 21, and will not restrict the movement of the first component 21.

[0053] The first elastic conductor 2151 and the second elastic conductor 2152 are conductors that deform under stress and can return to their initial shape after the external force is removed. The first elastic conductor 2151 and the second elastic conductor 2152 can be made of high-entropy high-strength memory alloy or gold wire, or they can be stretchable rubber containing spiral or serpentine metal conductors.

[0054] In this application, the "high-entropy high-strength shape memory alloy" can be an alloy containing titanium, nickel, copper, zirconium, yttrium, and boron; an alloy containing titanium, zirconium, hafnium, cobalt, nickel, and copper; or an alloy containing titanium, zirconium, hafnium, aluminum, and niobium. The "gold wire" contains at least one element selected from platinum, gold, palladium, hafnium, and copper. The "stretchable rubber containing spiral or serpentine arranged metal wires" may contain at least one element selected from copper, silver, gold, and zinc, and the stretchable rubber may contain materials such as polydimethylsiloxane or cis-1,4-polybutadiene rubber.

[0055] In some implementations, please refer to Figure 1 and Figure 2 The circuit board 1 also includes a first temperature sensor 11, which is used to detect the temperature on the outside of the circuit board 1. The first component 21 also includes a second temperature sensor 216, which is used to detect the temperature inside the first cavity 251. The first driving chip 214 is used to control the magnetic field of the first magnetic control unit 213 and control the first component 21 to move toward the first magnetic unit 121 or toward the second magnetic unit 122 according to the detection data of the first temperature sensor 11 and the detection data of the second temperature sensor 216.

[0056] In some implementations, please refer to Figure 1 and Figure 2The circuit board 1 also includes a first pillar 151 and a second pillar 152. A first part 141 and a third part 143 are respectively connected to the two ends of the first pillar 151, and a second part 142 and a fourth part 144 are respectively connected to the two ends of the second pillar 152. The first pillar 151 is provided with a first magnetic structure 161, and the second pillar 152 is provided with a second magnetic structure 162. The first driving chip 214 controls the first magnetic structure 161 and / or controls the second magnetic structure 162 to attract the first magnetic control unit 213 to drive the first component 21 to move toward the first pillar 151 or the second pillar 152.

[0057] In some implementations, please refer to Figure 1 and Figure 2 The position of the first movable opening 212 corresponds to the position of the first opening 131, and the position of the first blowing device 211 corresponds to the position of the second opening 132. That is, the orthographic projection of the first opening 131 overlaps with the first movable opening 212, and the orthographic projection of the first blowing device 211 overlaps with the second opening 132, which is conducive to air circulation inside and outside the wearable device 100.

[0058] In some implementations, the first component 21 may be a circuit board structure.

[0059] In some implementations, please refer to Figure 1 The circuit board 1 also has a third opening 133 and a fourth opening 134, which communicate with the first cavity 251. The circuit board 1 further includes a fifth portion 145 and a sixth portion 146, with the fifth portion 145 spaced apart from the second portion 142 via the third opening 133, and the sixth portion 146 spaced apart from the fourth portion 144 via the fourth opening 134. The wearable device 100 also includes a second component 22, which is suspended within the first cavity 251. One end of the second component 22 is connected to the second portion 142 and the fourth portion 144 via a third elastic wire, and the opposite end of the second component 22 is connected to the fifth portion 145 and the sixth portion 146 via a fourth elastic wire.

[0060] The third opening 133 is arranged side-by-side with the first opening 131, spaced apart by a second portion 142. The fourth opening 134 is also arranged side-by-side with the second opening 132, spaced apart by a fourth portion 144. The third opening 133 is also located on the outside of the wearable device 100, and the fourth opening 134 is also located on the inside of the wearable device 100. The third opening 133 and the fourth opening 134 also provide channels for air circulation between the inside and outside of the wearable device 100. The second component 22 is electrically connected to the circuit board 1 via the third and fourth elastic wires. Because the third and fourth elastic wires are elastic, they can provide support for the second component 22 to be suspended within the circuit board 1. Furthermore, when the second component 22 is displaced, the third and fourth elastic wires will not impede its movement or restrict its movement.

[0061] The materials of the third elastic conductor and the fourth elastic conductor are similar to those of the first elastic conductor 2151 and the second elastic conductor 2152. It can be understood that any conductor that can deform under force and recover its initial shape after the external force is removed can be used as the material of the third elastic conductor and the fourth elastic conductor.

[0062] In some embodiments, the second component 22 has the same structure as the first component 21, that is, the second component 22 has a second air blowing device, a second movable opening, a second magnetic control unit, a second driving chip, a third temperature sensor, a second resistor, a second heat dissipation hole, and a second sidewall opening. Furthermore, the positional relationship of the components of the second component 22 is the same as that of the components of the first component 21.

[0063] In some implementations, please refer to Figure 1 The first pillar 151 is connected at both ends to the first part 141 and the third part 143, respectively, and the second pillar 152 is connected at both ends to the fifth part 145 and the sixth part 146, respectively. The first pillar 151 is provided with a first magnetic structure 161, and the second pillar 152 is provided with a second magnetic structure 162.

[0064] The first pillar 151, the second pillar 152, the first part 141, the second part 142, the third part 143, the fourth part 144, the fifth part 145, and the sixth part 146 surround and form the first cavity 251. The first component 21 and the second component 22 are located inside the first cavity 251. The first cavity 251 provides space for the first component 21 and the second component 22 to move, as well as space for air circulation inside and outside the wearable device 100 and air circulation inside the wearable device 100.

[0065] The first magnetic structure 161, the second magnetic structure 162, the first magnetic unit 121, the second magnetic unit 122, the third magnetic unit 123, and the fourth magnetic unit 124 are used to generate a magnetic field. When they generate a magnetic field of opposite polarity to the first magnetocontrol unit 213 and the second magnetocontrol unit (not shown), they can attract the first component 21 and the second component 22 to move toward them. When they generate a magnetic field of the same polarity as the first magnetocontrol unit 213 and the second magnetocontrol unit (not shown), they can generate a magnetic force that repels the first component 21 and the second component 22, that is, they can cause the first component 21 and the second component 22 to move away from them.

[0066] In some implementations, please refer to Figure 1 The circuit board 1 also has a fifth opening 135 and includes a seventh portion 147 and an eighth portion 148, which are spaced apart by the fifth opening 135. The wearable device 100 also includes a third component 23, one end of which is electrically connected to the third portion 143 and the seventh portion 147 via a fifth flexible wire, and the other end of which is electrically connected to the fourth portion 144 and the eighth portion 148 via a sixth flexible wire.

[0067] In some embodiments, the third component 23 also has the same structure as the first component 21, that is, the third component 23 has a third air blowing device, a third movable opening, a third magnetic control unit, a third driving chip, a fourth temperature sensor, a third resistor, a third heat dissipation hole, and a third sidewall opening. Furthermore, the positional relationship of the components of the third component 23 is the same as that of the components of the first component 21.

[0068] In some implementations, please refer to Figure 1 The circuit board 1 also has a sixth opening 136 and includes a ninth portion 149, which is spaced apart from the eighth portion 148 by the sixth opening 136. The wearable device 100 also includes a fourth component 24, one end of which is electrically connected to the fourth portion 144 and the eighth portion 148 via a seventh flexible wire, and the other end of which is electrically connected to the sixth portion 146 and the ninth portion 149 via an eighth flexible wire.

[0069] In some embodiments, the circuit board 1 further includes a third pillar 153 and a fourth pillar 154. The opposite ends of the third pillar 153 are connected to the third portion 143 and the seventh portion 147, respectively, and the opposite ends of the fourth pillar 154 are connected to the sixth portion 146 and the ninth portion 149, respectively. The third pillar 153 is provided with a third magnetic structure 163, and the fourth pillar 154 is provided with a fourth magnetic structure 164.

[0070] In some embodiments, the third portion 143, the fourth portion 144, the sixth portion 146, the seventh portion 147, the eighth portion 148, the ninth portion 149, and the third pillar 153 and the fourth pillar 154 of the circuit board 1 surround to form a second cavity 252. The third component 23 and the fourth component 24 are located within the second cavity 252. The second cavity 252 provides space for the third component 23 and the fourth component 24 to move, as well as space for air circulation inside and outside the wearable device 100 and air circulation inside the wearable device 100.

[0071] In some embodiments, the fourth component 24 also has the same structure as the first component 21, that is, the fourth component 24 has a fourth air blowing device, a fourth movable opening, a fourth magnetic control unit, a fourth driving chip, a fifth temperature sensor, a fourth resistor, a fourth heat dissipation hole, and a fourth side wall opening. Furthermore, the positional relationship of the components of the fourth component 24 is the same as that of the components of the first component 21.

[0072] The working principle of the wearable device 100 provided in this application is as follows:

[0073] Please see Figure 1 , Figure 4 and Figure 7 When the external temperature is much higher than the internal temperature, the first driving chip 214 energizes the first energized coil 1211 and the second energized coil 1212, causing the first energized coil 1211 to generate a magnetic field of opposite polarity to the first magnetic unit 121, and causing the second energized coil 1212 to generate a magnetic field of the same polarity as the second magnetic unit 122. Based on the principle that like poles repel and unlike poles attract, the first component 21 moves upward under the influence of the magnetic field, reaching the first opening 131 and fitting tightly against it. Similarly, the second driving chip drives the second component 22 in the same way, causing the second component 22 to move upward under the influence of the magnetic field, reaching the third opening 133 and fitting tightly against it.

[0074] At this time, the first component 21, the second component 22, the third component 23 and the fourth component 24 can operate in the following three ways to block the external high temperature from radiating into the wearable device 100, so that the internal temperature of the wearable device 100 and the temperature inside the wearable device 100 are less affected by the outside.

[0075] Method 1: The first movable opening 212 of the first component 21 and the second movable opening of the second component 22 are simultaneously and fully opened. The first air blowing device 211 and the second air blowing device rotate counterclockwise simultaneously, that is, the first air blowing device 211 blows air towards the first movable opening 212, and the second air blowing device blows air towards the second movable opening. Furthermore, the power of the first air blowing device 211 and the second air blowing device can be turned to maximum to prevent external temperature from radiating into the wearable device 100, thereby maintaining the temperature balance inside and on the inner side of the wearable device 100. At this time, the first resistor 217 and the second embedded resistor are not energized.

[0076] Method 2: The first and second movable openings are simultaneously and completely closed. The third and fourth air-blowing devices rotate clockwise simultaneously, with the third air-blowing device blowing air in a direction away from the third movable opening and the fourth air-blowing device blowing air in a direction away from the fourth movable opening. At this time, the first and second movable openings are completely closed, reducing the external temperature radiation into the wearable device 100. Simultaneously, the clockwise rotation of the third and fourth air-blowing devices cools the interior and inner sides of the wearable device 100, maintaining temperature balance within the wearable device 100.

[0077] Method 3: The third air blowing device rotates counterclockwise, and the fourth air blowing device rotates clockwise. The first air blowing device 211 and the second air blowing device are adjusted according to the actual situation to minimize the influence of the external environment on the temperature inside and on the inner side of the wearable device 100. At this time, the third air blowing device blows air towards the third movable opening, and the fourth air blowing device blows air away from the fourth movable opening. The first air blowing device 211 and the second air blowing device are adjusted according to the actual situation to achieve internal air circulation inside the wearable device 100, thereby reducing the influence of the external temperature.

[0078] Please see Figure 1 , Figure 4 and Figure 8When the external temperature is slightly lower than the internal and inner temperature of the wearable device 100, the first driving chip 214 energizes the fifth energized coil 1215, causing the fifth energized coil 1215 to generate a magnetic field of opposite polarity to the adjacent first magnetic structure 161. Similarly, the fifth energized coil 1215 on the second magnetocontrol unit also generates a magnetic field of opposite polarity to the adjacent second magnetic structure 162. Meanwhile, the fifth energized coil 1215 on the first magnetocontrol unit 213 and the adjacent fifth energized coil 1215 on the second magnetocontrol unit generate magnetic fields of the same polarity. According to the principle that like poles repel and unlike poles attract, the first component 21 moves toward the first support column 151 and the second component 22 moves toward the second support column 152, providing a wider space for air circulation and circulation inside the wearable device 100. The first movable opening 212 and the second movable opening can be opened appropriately, and the first blowing device 211 and the second blowing device can be closed or rotated counterclockwise to maintain the temperature balance inside and inside the wearable device 100, so that internal circulation can be achieved inside the wearable device 100, thereby reducing the influence of external temperature.

[0079] Please see Figure 1 , Figure 4 and Figure 7 When the external temperature of the wearable device 100 is much lower than the internal and inner temperatures, the first driving chip 214 energizes the first energized coil 1211 and the second energized coil 1212 of the first magnetic control unit 213. This causes the first energized coil 1211 to generate a magnetic field of opposite polarity to the first magnetic unit 121, and the second coil to generate a magnetic field of the same polarity as the second magnetic unit 122. This causes the first component 21 to move upward toward the first opening 131 and fit into the first opening 131. Similarly, the second component 22 is moved upward toward the third opening 133 and fits into the third opening 133 in the same manner. Meanwhile, the first movable opening 212 and the second movable opening are completely closed. The first resistor 217 and the second embedded resistor are energized to generate heat. The heat is radiated into the inside and inside of the wearable device 100 through the first heat dissipation hole 218 and the second heat dissipation hole. The first blowing device 211 and the second blowing device rotate clockwise, that is, the first blowing device 211 blows air away from the first movable opening 212 and the second blowing device blows air away from the second movable opening. This accelerates the temperature circulation inside the wearable device 100, maintains the temperature balance inside and inside the wearable device 100, and is not affected by the low temperature outside, thus achieving the effect of heat preservation.
