Description

Technical Field

[0001] This invention relates to an electronic information acquisition device, and more particularly to a flexible wearable electronic information acquisition device. Background Technology

[0002] Knee braces are wearable devices that cover the knee area, typically providing protection against impacts and insulation. However, existing knee braces have several shortcomings: First, the power generation devices in current knee braces, which collect electronic information from the knee area, are usually too rigid and lack flexibility, resulting in poor comfort and low power generation efficiency when utilizing knee flexion and extension movements. Second, comfort and anti-slip properties are difficult to balance. During frequent knee flexion and extension, the knee brace tends to slip significantly, moving and contracting towards the knee or lower leg, causing discomfort during subsequent flexion and extension. Some knee braces with better anti-slip properties often use increased elasticity to clamp the leg; however, as the leg bends with the knee, the tissues in the knee area expand, causing constriction and reducing comfort. Others may use traction mechanisms connected to a waist belt or lumbar support. While designed to prevent slippage and slippage (similar to the principle of garter stockings), knee braces, especially during frequent exercise (such as long runs), cause constant friction against the skin of the thighs and legs, affecting comfort. Furthermore, achieving both ventilation and insulation is difficult, reducing comfort. For knee braces, during frequent exercise, heat generated around the knee and legs should be quickly dissipated to prevent stuffiness, thus increasing ventilation and cooling. After exercise stops for a period, insulation is necessary to prevent discomfort caused by continued evaporation of sweat and subsequent temperature drops (such as joint pain and muscle soreness), thus reducing ventilation and increasing insulation. Finally, traditional knee braces are ineffective at improving knee and leg discomfort after exercise, highlighting the shortcomings of current technology. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible wearable electronic information collection device to solve the technical problems of existing knee braces in collecting electronic information from the knee, which make it difficult to balance comfort, anti-slip properties, ventilation and heat preservation, as well as low power generation efficiency and difficulty in improving knee and leg discomfort.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flexible wearable electronic information acquisition device includes a knee brace, a controller, a battery, a current sensor, a voltage sensor, a radio transmission module, a detection component, an upper flexible electromagnetic coil, an upper flexible permanent magnet, a mounting base, and an elastic airbag rod. The knee brace is made of a flexible, elastic, and breathable fabric. The bottom of the knee brace can fully wrap the bulge of the calf muscle. The knee brace is equipped with a controller and a battery. The controller has an internally connected current sensor, voltage sensor, and radio transmission module. At least one set of detection components is fixed to the upper part of the knee brace. The detection component includes an upper flexible electromagnetic coil and an upper flexible permanent magnet. The upper flexible electromagnetic coil and the upper flexible permanent magnet are located on the left and right sides of the knee brace, respectively. The controller, battery, upper flexible electromagnetic coil, and upper flexible permanent magnet are electrically connected. A set of flexible mounting bases is fixed to the left and right sides of the outer side of the knee brace. Each set of mounting bases includes two corresponding mounting bases, with the back-to-back portions of the two mounting bases in each set being closed. Each set of mounting bases has a detachable elastic airbag rod inserted into it.

[0005] Based on the above technical solution, at least one set of ventilation components is fixed to the outer side of the knee brace. Each ventilation component includes two upper airbags, two compression springs, two traction buckles, and a strap. The two elastic upper airbags in one set of ventilation components are located on the upper left and upper right sides of the knee brace, respectively. A compression spring is fixed inside each upper airbag, with its two axial ends fixed to both sides of the inner wall of the upper airbag. A traction buckle is fixed outside each upper airbag, corresponding to the axial ends of the compression springs. Two traction buckles in one set of ventilation components are interspersed with a non-elastic, adjustable strap. Each upper airbag is fixedly connected to an air inlet and an air outlet. A one-way valve is fixed inside each air inlet and air outlet, respectively. The valve only allows gas to enter the upper airbag, and the one-way valve in the exhaust nozzle only allows gas to exit the upper airbag. The knee brace is fixed with at least two air inlet seats and two exhaust seats. The air inlet seats and exhaust seats are made of flexible, sealed material and have cavities inside. The air inlet seats have multiple air inlets and are fixed with exhaust pipes. The air inlets and exhaust pipes are respectively connected to the cavities of the air inlet seats. The exhaust seats have multiple exhaust holes and are fixed with air inlets. The exhaust holes and air inlets are respectively connected to the exhaust seats. The air inlets and exhaust holes pass through the knee brace and face the wearer's skin. Each air inlet is connected to the exhaust pipe through an excess hose for air passage. Each exhaust nozzle is connected to the air inlet through an excess hose for air passage.

[0006] Based on the above technical solution, the ventilation component and the detection component are both in two groups. The upper flexible electromagnetic coil and the upper flexible permanent magnet are respectively wrapped by the ends of the upper airbag away from the knee pad and correspond to the axial ends of the compression spring.

[0007] Based on the above technical solution, the air intake seat includes a front air intake seat and a rear air intake seat, and the exhaust seat includes a front exhaust seat and a rear exhaust seat. There are two front air intake seats and two rear air intake seats. The two front air intake seats are located on the left front side and the right front side of the bottom of the knee pad, respectively, and are vertically arranged. The two rear air intake seats are located on the left side and the right side of the bottom of the knee pad, respectively, and are vertically arranged. There are two front exhaust seats and two rear exhaust seats. The two front exhaust seats are located on the upper front part of the knee pad, respectively, and are horizontally arranged. The two rear exhaust seats are located on the upper left and the upper right part of the knee pad, respectively, and are vertically arranged.

[0008] Based on the above technical solution, a flexible temperature sensor and an upper flexible electric heating pad are attached and fixed to the upper part of the front middle of the knee brace. The flexible temperature sensor is located on the inner wall of the knee brace, and the upper flexible electric heating pad is located on the outer wall of the knee brace. Lower flexible electric heating pads are attached and fixed to the lower left and lower right parts of the knee brace, respectively. The lower flexible electric heating pads correspond to the gastrocnemius muscle of the calf. The flexible temperature sensor, the upper flexible electric heating pad, and the lower flexible electric heating pad are electrically connected to the controller.

[0009] Based on the above technical solution, main airbags are fixed to the left and right front sides of the bottom of the knee brace, and auxiliary airbags are fixed to the lower left and lower right sides of the inner side of the knee brace. A lower flexible electromagnetic coil and a lower flexible permanent magnet are fixed to both sides of the inner wall of the main airbag. The lower flexible electromagnetic coil and the lower flexible permanent magnet correspond to each other and are electrically connected to the controller. The main airbag and the auxiliary airbag are respectively fixedly connected to air nozzles. The air nozzles of the two main airbags are respectively connected to the air nozzles of the two auxiliary airbags through the excess tubing. The main airbag and the auxiliary airbag are filled with air. The air in the main airbag and the auxiliary airbag can only inflate one of them. The auxiliary airbag corresponds to the gastrocnemius muscle of the calf.

[0010] Based on the above technical solution, the knee brace includes hooks and adjustment buckles. The knee brace is open-ring shaped, with triangular openings on the upper left and right sides. These openings are used to match the sides and back of the knee joint. Multiple hooks are fixed sequentially from top to bottom on the right rear end of the knee brace. Multiple sets of adjustment buckles are fixed sequentially from top to bottom on the left outer side of the knee brace. The number of sets of adjustment buckles is the same as the number of hooks. Multiple adjustment buckles in each set are arranged front to back. Each set of adjustment buckles corresponds to each hook on the left and right. The adjustment buckles can be hooked onto the hooks so that the knee brace can wrap around the knee and lower leg. The upper flexible electric heating pad is located in front of and below the openings, and the ventilation component is located in front of the opening.

[0011] Based on the above technical solution, the strap includes a strap body and a Velcro fastener. The strap body is made of non-elastic flexible fabric. The strap body is open-loop and has a Velcro fastener fixed at the rear. The female buckle of the Velcro fastener is fixed to the left rear left end of the strap body, and the female buckle of the Velcro fastener is fixed to the right rear left end of the strap body.

[0012] Based on the above technical solution, the flexible wearable electronic information connection device also includes a stocking. The stocking is located inside the knee brace and is in direct contact with the skin of the knee and lower leg. The knee brace wraps around the stocking. The stocking is made of elastic and breathable fabric and is taller than the knee brace. The upper and lower parts of the stocking protrude from the upper and lower parts of the knee brace. Both the upper and lower inner parts of the knee brace and the upper and lower inner parts of the stocking are provided with a silicone anti-slip coating. The controller is a flexible controller that can be bent and corresponds to the tibialis anterior muscle on the outer side of the lower leg. The battery corresponds to the tibia on the inner side of the lower leg. Two flexible mounting cylinders are fixed at the bottom of the knee brace. The two mounting cylinders correspond to each other vertically and their opposite ends are closed. The battery is inserted into the two mounting cylinders.

[0013] Based on the above technical solution, the material composition of the socks is 60%-70% nylon + 20%-30% spandex + 10%-20% cotton, the material composition of the knee pads is 60%-70% polyester + 30%-40% spandex, and the radio transmission module is a BLE module.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention improves the overall anti-slip effect of the knee brace compared to the leg by setting up an elastic airbag rod, a stocking, and a silicone anti-slip coating, without the need to add elasticity to the knee brace to avoid discomfort from tightness, thus ensuring comfort; and the upper flexible electromagnetic coil, upper flexible permanent magnet and elastic airbag rod can all be flexibly bent, thus improving comfort. The upper airbag expands and contracts by bending the legs, and then the one-way valve enables rapid ventilation of the legs, improving the ventilation effect. However, the ventilation effect is not enhanced when the legs are bent slightly or not bent, thus ensuring the heat preservation effect. During the expansion and contraction of the upper airbag, the upper flexible electromagnetic coil and the upper flexible permanent magnet also reciprocate. Compared to the reciprocating movement of the human tissue at the knee, the amplitude of the reciprocating movement is greater, thereby increasing the change in magnetic flux and thus improving the power generation efficiency. The power generation efficiency can also be improved by setting two sets of detection components. The flexible temperature sensor can detect and collect the temperature of the area below the patella. By controlling the upper and lower flexible electric heating pads, the area around the patella and the lower leg can be heated, which can promote local blood flow, reduce lactic acid buildup, and improve comfort. After exercise, by frequently applying current to the lower flexible electromagnetic coil through the controller, the lower flexible electromagnetic coil and the lower flexible permanent magnet can be magnetically attracted and repelled. This causes the main airbag to reciprocate and expand, and then the secondary airbag to reciprocate and expand through the air flow. This allows for reciprocating pressure on the calf, promoting blood circulation, relieving muscle fatigue, reducing lactic acid buildup, and improving comfort. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4As shown, a flexible wearable electronic information acquisition device includes a knee brace 1, a controller 2, a battery 3, a current sensor, a voltage sensor, a radio transmission module, a detection component, an upper flexible electromagnetic coil 8, an upper flexible permanent magnet 9, a mounting base 10, and an elastic airbag rod 11. The knee brace 1 is made of a flexible, elastic, and breathable fabric. The bottom of the knee brace 1 can fully wrap the bulge of the calf muscle. The knee brace 1 is equipped with the controller 2 and the battery 3. The controller 2 has a built-in electrically connected current sensor, voltage sensor, and radio transmission module. At least one [missing information - likely a device name or component] is fixed to the upper part of the knee brace 1. The detection assembly includes an upper flexible electromagnetic coil 8 and an upper flexible permanent magnet 9, which are located on the left and right sides of the knee brace 1, respectively. The controller 2, the battery 3, the upper flexible electromagnetic coil 8 and the upper flexible permanent magnet 9 are electrically connected. A set of flexible mounting seats 10 is fixed on each of the left and right sides of the outer side of the knee brace 1. Each set of mounting seats 10 includes two corresponding mounting seats 10, one above the other. The back-to-back parts of the two mounting seats 10 in a set of mounting seats 10 are closed. Each of the two sets of mounting seats 10 is connected to a detachable elastic airbag rod 11.

[0022] In use, the knee brace 1 is worn, with the upper flexible electromagnetic coil 8 and lower flexible electromagnetic coil 35 positioned in the upper depressions on either side of the patella. The elastic airbag rod 11 crosses the knee joint and extends to the thigh and calf. As the leg bends with the knee, the distance between the depressions on either side of the patella increases and decreases, causing the relative movement of the upper flexible electromagnetic coil 8 and the upper flexible permanent magnet 9 to cause a reciprocating change in magnetic flux, thus generating electricity. This electricity is then processed by the controller 2 and stored in the battery 3. During this process, current and voltage sensors can detect the current and voltage of the generated energy in real time. As the degree of leg bending with the knee changes, the voltage and current of the generated energy also differ, thus allowing the calculation of the angle of leg bending with the knee, i.e., real-time power generation. The system collects electronic information about the leg bending angle and then outputs the relevant data to the outside world via a radio transmission module. During the leg bending along with the knee, the elastic airbag rod 11 can bend along with the knee, while maintaining a certain degree of rigidity and elasticity, exhibiting a tendency to recover. Therefore, it can prevent the upper part of the knee brace 1 from shifting downwards, avoiding the upper part of the knee brace 1 from contracting and gathering towards the knee. Simultaneously, because the bottom of the knee brace 1 can fully wrap around the bulge of the gastrocnemius muscle in the calf, it can greatly reduce the phenomenon of sliding down the calf, thus achieving an anti-slip effect without needing to increase the elasticity of the knee brace 1 to avoid discomfort from tightness, ensuring comfort. Furthermore, the upper flexible electromagnetic coil 8, the upper flexible permanent magnet 9, and the elastic airbag rod 11 can all bend flexibly, thus improving comfort.

[0023] At least one set of ventilation components is fixed to the outer side of the knee brace 1. Each ventilation component includes two upper airbags 13, two compression springs 14, two traction buckles 15, and a strap 16. The two elastic upper airbags 13 in one set of ventilation components are located on the upper left and upper right sides of the knee brace 1, respectively. A compression spring 14 is fixed inside each upper airbag 13, with its two axial ends fixed to the inner walls of the upper airbag 13. A traction buckle 15 is fixed outside each upper airbag 13, corresponding to the axial ends of the compression springs 14. A non-elastic, adjustable strap 16 is inserted through the two traction buckles 15 in one set of ventilation components. Each upper airbag 13 is fixedly connected to an air inlet 17 and an air outlet 18. A one-way valve 19 is fixed inside each air inlet 17 and air outlet 18, respectively. The one-way valve 19 in the air inlet 17 only allows air to enter the upper airbag. The airbag 13 has a one-way valve 19 inside the exhaust nozzle 18 that allows gas to be discharged from the upper airbag 13. The knee pad 1 is fixed with at least two air intake seats 20 and two exhaust seats 21. The air intake seats 20 and exhaust seats 21 are made of flexible, sealed material and have cavities inside. The air intake seats 20 have multiple air intake holes 22 and are fixed with exhaust pipes 23. The air intake holes 22 and exhaust pipes 23 are respectively connected to the cavities of the air intake seats 20. The exhaust seats 21 have multiple exhaust holes 24 and are fixed with air intake pipes 25. The exhaust holes 24 and air intake pipes 25 are respectively connected to the exhaust seats 21. The air intake holes 22 and exhaust holes 24 pass through the knee pad 1 and face the wearer's skin. Each air intake nozzle 17 is connected to the exhaust pipe 23 through a spare hose for air passage. Each exhaust nozzle 18 is connected to the air intake pipe 25 through a spare hose for air passage.

[0024] Furthermore, when the leg is not bent, the strap 16 is slightly tightened without compressing the upper airbag 13. As the leg bends with the knee, the volume of the tissue at the knee expands, and the binding effect of the strap 16 becomes inconvenient, thus causing the upper airbag 13 to compress. When returning to the unbent state, the upper airbag 13 gradually recovers under the elastic repulsive force of the compression spring 14. That is, the upper airbag 13 is expanded and contracted through the bending of the leg. Then, using the action of the one-way valve 19, outside air can enter the upper airbag 13 through the air inlet 22, air inlet seat 20, exhaust pipe 23, and air inlet nozzle 17, and then be discharged to the outside through the exhaust nozzle 18, air inlet pipe 25, exhaust seat 21, and exhaust hole 24. This allows for rapid ventilation of the leg when the leg is bent significantly, improving the ventilation effect. However, when the leg is bent slightly or not bent, the ventilation effect is not enhanced, thus ensuring the heat preservation effect.

[0025] The ventilation assembly and the detection assembly each have two sets. The upper flexible electromagnetic coil 8 and the upper flexible permanent magnet 9 are respectively wrapped by the ends of the upper airbag 13 away from the knee pad 1, and correspond to the axial ends of the compression spring 14.

[0026] Furthermore, the upper flexible electromagnetic coil 8 and the upper flexible permanent magnet 9 are respectively wrapped by the ends of the upper airbag 13 away from the knee pad 1, so that when the upper airbag 13 extends and retracts, the upper flexible electromagnetic coil 8 and the upper flexible permanent magnet 9 also reciprocate. Compared with only following the reciprocating movement of human tissue at the knee, the amplitude of their reciprocating movement is greater, thereby increasing the change in magnetic flux and thus improving the power generation efficiency. By setting two sets of detection components, the power generation efficiency can also be improved.

[0027] The air intake seat 20 includes a front air intake seat 26 and a rear air intake seat 27, and the exhaust seat 21 includes a front exhaust seat 28 and a rear exhaust seat 29. There are two front air intake seats 26 and two rear air intake seats 27. The two front air intake seats 26 are located on the left front side and the right front side of the bottom of the knee pad 1, respectively, and are vertically arranged. The two rear air intake seats 27 are located on the left side and the right side of the bottom of the knee pad 1, respectively, and are vertically arranged. There are two front exhaust seats 28 and two rear exhaust seats 29. The two front exhaust seats 28 are located on the upper front part of the knee pad 1, respectively, and are horizontally arranged. The two rear exhaust seats 29 are located on the upper left and the upper right part of the knee pad 1, respectively, and are vertically arranged.

[0028] Furthermore, by defining the positions of the air intake seat 20 and the exhaust seat 21, the upper airbag 13 can draw in air from the lower leg area through the front air intake seat 26 and the rear air intake seat 27 when it extends and retracts, and then expel the air to the thigh area above the knee through the front exhaust seat 28 and the rear exhaust seat 29, making the ventilation areas more dispersed and improving comfort.

[0029] A flexible temperature sensor 30 and an upper flexible electric heating pad 31 are fixedly attached to the upper part of the front middle of the knee brace 1. The flexible temperature sensor 30 is located on the inner wall of the knee brace 1, and the upper flexible electric heating pad 31 is located on the outer wall of the knee brace 1. Lower flexible electric heating pads 32 are fixedly attached to the lower left and lower right parts of the knee brace 1, respectively. The lower flexible electric heating pads 32 correspond to the gastrocnemius muscle of the calf. The flexible temperature sensor 30, the upper flexible electric heating pad 31 and the lower flexible electric heating pad 32 are electrically connected to the controller 2.

[0030] Furthermore, the flexible temperature sensor 30 can detect and collect information on the temperature of the lower part of the patella. Under normal physiological conditions, the temperature around the patella is lower than that of other parts of the leg. When the temperature here is detected to be below the threshold, the controller 2 will activate the upper flexible electric heating pad 31 to heat the area around the patella. This has a significant effect on improving "old cold legs" and low knee temperature caused by continuous evaporation of sweat after exercise, thereby improving comfort. When the temperature here is detected to be above the threshold, the controller 2 will control the upper flexible electric heating pad 31 to stop working. The controller 2 can also control the lower flexible electric heating pad 32 to work independently or in conjunction with the upper flexible electric heating pad 31 to heat the calf area, especially the gastrocnemius muscle. After high-intensity exercise, this can promote local blood flow, reduce lactic acid accumulation, and improve comfort.

[0031] The knee brace 1 has a main airbag 33 fixed to the left front side and right front side of its bottom, and a secondary airbag 34 fixed to the lower left and lower right sides of its inner side. A lower flexible electromagnetic coil 35 and a lower flexible permanent magnet 36 are fixed to the inner walls of the main airbag 33, respectively. The lower flexible electromagnetic coil 35 and the lower flexible permanent magnet 36 correspond to each other and are electrically connected to the controller 2. The main airbag 33 and the secondary airbag 34 are respectively fixedly connected to air nozzles. The air nozzles of the two main airbags 33 are respectively connected to the air nozzles of the two secondary airbags 34 through the excess tubing. The main airbag 33 and the secondary airbag 34 are filled with air. The air in the main airbag 33 and the secondary airbag 34 can only inflate one of them. The secondary airbag 34 corresponds to the gastrocnemius muscle of the calf.

[0032] Furthermore, after exercise, by frequently applying current to the lower flexible electromagnetic coil 35 through the controller 2, the lower flexible electromagnetic coil 35 and the lower flexible permanent magnet 36 can be magnetically attracted and magnetically repelled, thereby causing the main airbag 33 to reciprocate and expand, and then causing the auxiliary airbag 34 to reciprocate and expand through the gas flow, thereby reciprocating pressure on the calf, promoting blood circulation, relieving muscle fatigue, reducing lactic acid accumulation, and improving comfort.

[0033] The knee brace 1 includes hooks 37 and adjusting buckles 38. The knee brace 1 is open-ring shaped, and the upper middle part has triangular openings 44 on the left and right sides. The openings 44 are used to match the sides and back of the knee joint. Multiple hooks 37 are fixed from top to bottom on the right rear end of the knee brace 1. Multiple sets of adjusting buckles 38 are fixed from top to bottom on the left outer side of the knee brace 1. The number of sets of adjusting buckles 38 is the same as the number of hooks 37. Multiple adjusting buckles 38 in each set of adjusting buckles 38 are arranged front to back. Each set of adjusting buckles 38 corresponds to each hook 37 on the left and right. The adjusting buckles 38 can be hooked with the hooks 37 so that the knee brace 1 can wrap around the knee and lower leg. The upper flexible electric heating plate 31 is located in front of and lower front of the opening 44. The ventilation component is located in front of and upper front of the opening 44.

[0034] By setting the opening 44, the back of the knee can be bent more easily, reducing the obstruction of the knee brace 1 to knee bending and improving comfort. By changing the hook 37 and connecting it with different adjustment buckles 38, the initial inner diameter of the knee brace 1 can be adjusted to adapt to different leg sizes, thus improving comfort while ensuring anti-slip effect.

[0035] The strap 16 includes a strap body 39 and a Velcro 40. The strap body 39 is made of non-elastic flexible fabric. The strap body 39 is open-loop and the Velcro 40 is fixed at the rear. The female buckle of the Velcro 40 is fixed to the left rear left end of the strap body 39, and the female buckle of the Velcro 40 is fixed to the right rear left end of the strap body 39.

[0036] The tightness of the strap 16 can be adjusted by using different attachment positions of the Velcro 40 female and male hook-and-loop fasteners.

[0037] The flexible wearable electronic information connection device also includes a stocking 41, which is located inside the knee brace 1 and is in direct contact with the skin of the knee and lower leg. The knee brace 1 is wrapped around the stocking 41. The stocking 41 is made of elastic and breathable fabric and is taller than the knee brace 1. The upper and lower parts of the stocking 41 protrude from the upper and lower parts of the knee brace 1. Both the upper and lower inner parts of the knee brace 1 and the upper and lower inner parts of the stocking 41 are provided with a silicone anti-slip coating 42. The controller 2 is a flexible controller that can be bent and corresponds to the tibialis anterior muscle on the outer side of the lower leg. The battery 3 corresponds to the tibia on the inner side of the lower leg. Two flexible mounting cylinders 43 are fixed at the bottom of the knee brace 1. The two mounting cylinders 43 correspond to each other vertically and their opposite ends are closed. The battery 3 is inserted into the two mounting cylinders 43.

[0038] By setting the sock 41, the air inlet 22, exhaust 24, flexible temperature sensor 30, and auxiliary airbag 34 do not come into direct contact with the skin, thereby reducing the formation of marks and improving comfort. The sock 41, made of breathable fabric, is higher than the knee pad 1 and can extend to the upper thigh and ankle. With the silicone anti-slip coating 42 on the inner wall, it can improve breathability and anti-slip effect. The knee pad 1, which is set on the outside, can ensure the anti-slip effect with the sock 41 by utilizing the silicone anti-slip coating 42 on its inner wall. Combined with the silicone anti-slip coating 42 inside the sock 41, the overall anti-slip effect of the knee pad 1 compared to the leg is improved.

[0039] The socks 41 are made of 60%-70% nylon, 20%-30% spandex, and 10%-20% cotton. The knee pads 1 are made of 60%-70% polyester and 30%-40% spandex. The radio transmission module is a BLE module.

[0040] By setting a low-power BLE module, information can be exchanged between the mobile phone and the controller 2, and the controller 2 can be controlled.

[0041] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
