Description

Technical Field

[0001] This disclosure relates to a wireless transmission system, and more particularly to a wireless transmission system for use in wireless communication or wireless charging. Background Technology

[0002] With the development of technology, many products today have power-assisted functions. When users utilize these products, the power-assisted module provides power to make operation easier. For example, power-assisted modules can be applied to products such as electric bicycles or fishing reels. Due to this convenience, products with power-assisted modules are gradually becoming more popular.

[0003] Generally speaking, sensors need to be installed on the power assist module. Traditional sensors transmit data by wiring, and an additional power line is needed to provide the power required for the sensor. Therefore, when installed on products with rotary motors, long-term use can easily cause bending of the power line and transmission line, leading to failures such as breakage of the power line and transmission line.

[0004] Therefore, how to design a transmission system that can overcome the above-mentioned shortcomings is a topic worthy of discussion and solution today. Summary of the Invention

[0005] In view of this, this disclosure proposes a wireless transmission system to solve the above-mentioned problems.

[0006] This disclosure provides a wireless transmission system, including a first transmission module and a second transmission module. The first transmission module has a first coil. The second transmission module has a second coil corresponding to the first coil. The first transmission module is configured to transmit a first signal via the first coil to the second coil of the second transmission module.

[0007] According to some embodiments of this disclosure, a first transmission module includes a first power supply and a first signal processing component. The first signal processing component is configured to control a first coil. A second transmission module includes a second signal processing component and a first sensing component. The second signal processing component is configured to control a second coil. The first sensing component is configured to output a first sensing signal to the second signal processing component. The second transmission module is configured to transmit a second signal via the second coil to the first coil of the first transmission module. When the wireless transmission system is in a first time period, the second signal processing component converts the first signal into a first electrical signal. The first electrical signal is selectively input to the first sensing component. The first transmission module also includes a first computing element. When the wireless transmission system is in a second time period different from the first time period, the first signal processing component converts the second signal into a second electrical signal and inputs it to the first computing element. The extreme value of the first signal is different from the extreme value of the second signal. The extreme value of the first signal is greater than the extreme value of the second signal. The extreme value of the first signal is at least twice the extreme value of the second signal.

[0008] According to some embodiments of this disclosure, the second transmission module further includes a second sensing component configured to output a second sensing signal to a second signal processing component. The second signal processing component outputs a second signal based on the first sensing signal and the second sensing signal. The second signal processing component outputs the second signal based on preset information. The preset information is measured and defined by an external device and then recorded to the second transmission module. The wireless transmission system further includes a driving component configured to drive relative movement between the first transmission module and the second transmission module. The driving component is configured to operate according to a driving signal output by a first computing element of the first transmission module. The first transmission module is configured to output a driving signal based on a second electrical signal.

[0009] According to some embodiments of this disclosure, when the second signal processing component determines that the first sensing signal meets a first condition based on preset information, the second signal processing component outputs a second signal including first mode information to the first signal processing component. When the second sensing signal meets the first condition, the second signal processing component outputs a second signal including first mode information to the first signal processing component based on preset information. When the first transmission module receives the second signal including first mode information, the driving component drives the first transmission module and the second transmission module to move relative to each other in a first mode. When the second signal processing component determines that the first sensing signal meets a second condition based on preset information, the second signal processing component outputs a second signal including second mode information to the first signal processing component. When the second sensing signal meets the second condition, the second signal processing component outputs a second signal including second mode information to the first signal processing component based on preset information. When the first transmission module receives the second signal including second mode information, the driving component drives the first transmission module and the second transmission module to move relative to each other in a second mode.

[0010] According to some embodiments of this disclosure, when the second signal processing component determines that the first sensing signal meets a third condition based on preset information, the second signal processing component outputs a second signal including third mode information to the first signal processing component. When the first transmission module receives the second signal including the third mode information, the first transmission module outputs the first signal in a third mode. When the second signal processing component determines that the first sensing signal meets a fourth condition based on preset information, the second signal processing component outputs a second signal including fourth mode information to the first signal processing component. When the first transmission module receives the second signal including the third mode information, the first transmission module outputs the first signal in a fourth mode. The first signal is different from the second signal.

[0011] According to some embodiments of this disclosure, the power required by the first sensing component is directly provided by the second signal processing component, without any intermediate power storage element. The second signal processing component is configured to provide power to the first sensing component during a first time period. The length of the first time period differs from the length of the second time period. The length of the first time period is greater than the length of the second time period. The first signal processing component and the first computing element have an integrally formed structure. When the wireless transmission system is in an activation mode, the first signal is continuously transmitted via the first coil to the second coil. When the wireless transmission system is in activation mode, the second signal is continuously transmitted via the second coil to the first coil. When the wireless transmission system is in activation mode, the first time period and the second time period alternate.

[0012] According to some embodiments of this disclosure, the second transmission module further includes a second power supply, and a second signal processing component transmits a first electrical signal to the second power supply. The second power supply outputs a third electrical signal to the first sensing component. The second transmission module further includes a third sensing component. The second power supply is configured to output a fourth electrical signal and a fifth electrical signal to the second sensing component and the third sensing component, respectively. The third sensing component is configured to sense the power level of the second power supply and correspondingly output a third sensing signal to the second signal processing component. The second signal processing component is configured to monitor the power level of the second power supply based on the third sensing signal. When the first transmission module does not transmit the first signal to the second transmission module, the maximum power level of the second power supply in the second transmission module is less than 200mAh. The second transmission module further includes a safety component electrically connected to the second power supply. When the first transmission module does not transmit the first signal to the second transmission module for more than a first preset time, the safety component releases the power level of the second power supply to a safe value within a second preset time. The safety component is configured to convert the electrical energy of the second power supply into heat energy. The first preset time is less than 6 hours. The second preset time is less than 1 hour. The safe value is defined as half of the maximum power level of the second power supply. The second signal processing component is configured to monitor and determine whether the power level of the second power source has reached a safe value based on the third sensing signal.

[0013] According to some embodiments of this disclosure, the wireless transmission system further includes a spacer component disposed between the first coil and the second coil. The spacer component is made of metal. The frequency of the periodic first signal is greater than 1 MHz. The frequency of the periodic second signal is greater than 1 MHz. The spacer component has a plurality of through-holes. When viewed along the winding axis of the first coil, the boundary of the first coil surrounds and defines a first area. When viewed along the winding axis of the first coil, the area of ​​the metal portion of the spacer component is less than half of the first area. When viewed along the winding axis of the second coil, the boundary of the second coil surrounds and defines a second area. When viewed along the winding axis of the second coil, the area of ​​the metal portion of the spacer component is less than half of the second area.

[0014] According to some embodiments of this disclosure, the spacer member defines a first region and a second region. The first region has a third area. The second region surrounds the first region and has a fourth area. The proportion of metal in the spacer member in the first region is different from the proportion of metal in the spacer member in the second region. The proportion of metal in the spacer member in the first region is less than the proportion of metal in the spacer member in the second region. The perforations have a plurality of first perforations and a plurality of second perforations, respectively disposed in the first region and the second region. The ratio of the total area of ​​these first perforations to the third area is different from the ratio of the total area of ​​the second perforations to the fourth area. The ratio of the total area of ​​these first perforations to the third area is greater than the ratio of the total area of ​​the second perforations to the fourth area.

[0015] According to some embodiments of this disclosure, a first transmission module has a first housing. At least a portion of the first housing is located between a first coil and a second coil. The first housing is made of a non-metallic material. A second transmission module has a second housing. At least a portion of the second housing is located between the first coil and the second coil. The second housing is also made of a non-metallic material. A spacer is disposed in either the first or second housing. At least a portion of the spacer is embedded within either the first or second housing.

[0016] This disclosure provides a wireless transmission system including a first transmission module and a second transmission module. The second transmission module is movably connected to the first transmission module. The first transmission module is a second coil configured to transmit a first signal to the second transmission module via a first coil. A second signal processing component of the second transmission module can convert the first signal into an electrical signal to provide power to one or more sensing components, enabling them to sense parameters such as the rotational speed or torque of the second transmission module.

[0017] After receiving the sensing signals from these sensing components, the second signal processing component determines whether the sensing signals meet specific conditions based on preset information, such as low speed and high torque or high speed and low torque, and accordingly sends a second signal to the first transmission module via the second coil. The first transmission module then controls a drive component based on the second signal to change parameters such as the speed or torque of the second transmission module.

[0018] The wireless transmission system disclosed herein can be applied to products such as electric bicycles or fishing reels, and can provide auxiliary power to assist users according to their usage scenarios. Furthermore, since the coils and electronic components on the rotor (such as the second transmission module) can be powered or communicated without external wires, the problem of existing rotating modules damaging wires during rotation can be avoided.

[0080] Furthermore, in some embodiments of this disclosure, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or they may refer to two structures that are not in direct contact, with other structures disposed between them. Moreover, these terms regarding joining and connection may also include cases where both structures are movable or both structures are fixed.

[0081] Please refer to Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of a wireless transmission system 10 according to an embodiment of the present disclosure, and Figure 2 This is a functional block diagram of a wireless transmission system 10 according to an embodiment of the present disclosure. Figure 1As shown, the wireless transmission system 10 is a wireless transmission system that can be used to transmit energy or signals. In this embodiment, the wireless transmission system 10 may include a first transmission module 100 and a second transmission module 200.

[0082] The first transmission module 100 may have a first coil 111, the second transmission module 200 may have a second coil 211, and the first transmission module 100 is configured to transmit a first signal SG1 to the second coil 211 of the second transmission module 200 via the first coil 111.

[0083] In this embodiment, the first transmission module 100 may further have a first housing 102, at least a portion of which is located between the first coil 111 and the second coil 211, and the first housing 102 is made of a non-metallic material, such as plastic, but not limited thereto.

[0084] Similarly, the second transmission module 200 may further have a second housing 202, at least a portion of which is located between the first coil 111 and the second coil 211, and the second housing 202 is made of a non-metallic material, such as plastic, but not limited thereto.

[0085] Furthermore, such as Figure 1 As shown, the first transmission module 100 may further include a first circuit board 110. The first circuit board 110 is fixedly disposed on the first housing 102, and the first coil 111 is disposed on the first circuit board 110. The first circuit board 110 is disposed on the inner or outer wall surface of the first housing 102, and the first circuit board 110 is, for example, a flexible circuit board, but is not limited thereto.

[0086] Similarly, the second transmission module 200 may also include a base 208 and a second circuit board 210, wherein the second circuit board 210 is fixedly disposed on the base 208, and the second coil 211 is disposed on the second circuit board 210. The second circuit board 210 may be, for example, a flexible circuit board, but is not limited thereto.

[0087] like Figure 1 As shown, the wireless transmission system 10 may also include a hinge 109 and a drive assembly 120. The hinge 109 passes through the first housing 102 and the second housing 202 and is connected to the base 208. The drive assembly 120 is configured to drive relative movement between the first transmission module 100 and the second transmission module 200. For example, the drive assembly 120 may be connected to the hinge 109 for driving, and the drive assembly 120 may be, for example, a voice coil motor, but is not limited thereto.

[0088] In this embodiment, the base 208 is fixedly connected to the pivot 109, and the drive assembly 120 is capable of driving the base 208 to rotate relative to the first transmission module 100 about the pivot 109. However, the configuration of the base 208 is not limited to this. For example, the base 208 may also be fixed to the second housing 202, so that the drive assembly 120 can drive the second transmission module 200 to move relative to the first transmission module 100.

[0089] In this embodiment, the first transmission module 100 may be a stator, which may be fixed to another housing (not shown in the figure), while the base 208 or the second transmission module 200 may be a rotor, but is not limited thereto. In other embodiments, the drive assembly 120 may also be disposed within the second housing 202 to drive the base 208.

[0090] In some embodiments, the first housing 102 and the second housing 202 may be movably connected together, or the first housing 102 and the second housing 202 may be integrally formed. In some embodiments, the wireless transmission system 10 may be part of the drive mechanism of an electric bicycle, or part of a fishing reel, but is not limited thereto.

[0091] Next, please continue to refer to... Figure 2 as well as Figure 3 ,and Figure 3 This is a signal diagram of a first enable signal and a second enable signal relative to time according to an embodiment of the present disclosure. Figure 2 As shown, the first transmission module 100 may further include a first power supply 113 and a first signal processing component 115, and the first signal processing component 115 is configured to control the first coil 111. For example, the first power supply 113 may be a battery or external mains power, and the first signal processing component 115 may be a processing circuit or processing chip, which can be used to process signals, decode signals, or determine the timing of signal processing, etc.

[0092] Similarly, the second transmission module 200 may further include a second signal processing component 215 and a first sensing component 221, wherein the second signal processing component 215 is configured to control the second coil 211. The first sensing component 221 is configured to output a first sensing signal SES1 to the second signal processing component 215. For example, the first sensing component 221 may be a sensor disposed on the base 208 or the second circuit board 210 and configured to sense the rotational speed of the base 208, but is not limited thereto.

[0093] Similar to the first signal SG1, the second transmission module 200 is configured to transmit a second signal SG2 to the first coil 111 of the first transmission module 100 via the second coil 211. Specifically, when the wireless transmission system 10 is in an active mode (i.e., when the wireless transmission system 10 is turned on), the first signal SG1 is continuously transmitted to the second coil 211 via the first coil 111, and when the wireless transmission system 10 is in active mode, the second signal SG2 is also continuously transmitted to the first coil 111 via the second coil 211.

[0094] Next, as Figure 3 As shown, the first transmission module 100 and the second transmission module 200 are operated according to the first turn-on signal and the second turn-on signal, respectively. The first turn-on signal and the second turn-on signal can be generated by a turn-on signal generating circuit in the first signal processing component 115 and the second signal processing component 215, respectively. The first turn-on signal and the second turn-on signal are, for example, continuous square wave signals, but are not limited to this.

[0095] In this embodiment, when the wireless transmission system 10 is in a first time period T1, the second signal processing component 215 converts the first signal SG1 into a first electrical signal EC1 according to the second activation signal.

[0096] The first electrical signal EC1 is directly input to the first sensing component 221. That is, the first electrical signal EC1 can be used as power to supply the first sensing component 221, so that the first sensing component 221 can operate to sense.

[0097] It is worth noting that the power required by the first sensing component 221 (i.e., the first electrical signal EC1) is directly provided by the second signal processing component 215, without passing through any power storage components, such as batteries or capacitors for storing power. The second signal processing component 215 is configured to provide power to the first sensing component 221 during the first time period T1.

[0098] Furthermore, the first transmission module 100 also includes a first computing element 117, and when the wireless transmission system 10 is in a second time period T2 different from the first time period T1, the first signal processing component 115 converts the second signal SG2 into a second electrical signal EC2 and inputs it to the first computing element 117. The first computing element 117 may be, for example, a circuit or chip for computing.

[0099] In some embodiments, the first signal processing component 115 and the first computing element 117 may have an integrally formed structure. That is, the first signal processing component 115 and the first computing element 117 may be implemented by the same circuit. For example, they may both be implemented by a single microcontroller unit (MCU).

[0100] Additionally, in this embodiment, as Figure 2 As shown, the first signal SG1 and the second signal SG2 can be sine wave signals, but are not limited to this. The extreme value of the first signal SG1 (e.g., peak Vp1) is different from the extreme value of the second signal SG2 (e.g., peak Vp2). For example, the extreme value of the first signal SG1 is greater than the extreme value of the second signal SG2, and the extreme value of the first signal SG1 is at least twice the extreme value of the second signal SG2.

[0101] It is worth noting that when the wireless transmission system 10 is in the startup mode, the first time period T1 and the second time period T2 alternate, and the length of the first time period T1 is different from the length of the second time period T2.

[0102] For example, since the second transmission module 200 in this embodiment does not have a battery, the length of the first time period T1 that provides power to the first sensing component 221 is greater than the length of the second time period T2, so as to ensure that the first sensing component 221 can operate normally.

[0103] Furthermore, such as Figure 2 As shown, the second transmission module 200 may further include a second sensing component 222, disposed on the second circuit board 210 and configured to output a second sensing signal SES2 to the second signal processing component 215. For example, the second sensing component 222 may be a sensor disposed on the base 208 and configured to sense the torque of the base 208, but is not limited thereto.

[0104] Similarly, the second signal processing component 215 also converts the first signal SG1 into another electrical signal EC11 according to the second turn-on signal, so as to provide power to the second sensing component 222, enabling the second sensing component 222 to operate and sense. Similarly, there is no power storage element between the second sensing component 222 and the second signal processing component 215, such as no battery or capacitor for storing power.

[0105] In this embodiment, the second signal processing component 215 outputs a second signal SG2 based on the first sensing signal SES1 and the second sensing signal SES2. Furthermore, the second signal processing component 215 also outputs the second signal SG2 based on preset information. This preset information is measured and defined by an external device and then recorded to the second signal processing component 215 of the second transmission module 200. For example, the preset information may include conditional information such as rotational speed and torque.

[0106] After the first signal processing component 115 receives the second signal SG2 through the first coil 111, it sends the second electrical signal EC2 to the first calculation element 117. Then, the drive component 120 is configured to operate according to a drive signal CTS output by the first calculation element 117 of the first transmission module 100.

[0107] That is, the first computing element 117 of the first transmission module 100 is configured to output a drive signal CTS according to the second electrical signal EC2.

[0108] The aforementioned preset information may include multiple conditions for the second signal processing component 215 to make a judgment. For example, when the second signal processing component 215 determines that the first sensing signal SES1 meets a first condition based on the preset information, the second signal processing component 215 will output a second signal SG2 including a first mode information to the first signal processing component 115.

[0109] Similarly, when the second signal processing component 215 determines that the second sensing signal SES2 meets the first condition, the second signal processing component 215 will also output a second signal SG2 including the first mode information to the first signal processing component 115 according to preset information. The first condition is, for example, that the rotational speed of the second transmission module 200 is lower than a first preset rotational speed and the torque is higher than a first preset torque.

[0110] Therefore, when the first transmission module 100 receives the second signal SG2 including the first mode information, the first signal processing component 115 and the first computing element 117 control the drive component 120 to drive the first transmission module 100 and the second transmission module 200 to move relative to each other in a first mode. For example, in the first mode, the drive component 120 outputs an auxiliary power to increase the rotational speed of the second transmission module 200.

[0111] On the other hand, when the second signal processing component 215 determines that the first sensing signal SES1 meets a second condition based on preset information, the second signal processing component 215 outputs a second signal SG2 including a second mode information to the first signal processing component 115.

[0112] Similarly, when the second signal processing component 215 determines that the second sensing signal SES2 meets the second condition, the second signal processing component 215 will also output a second signal SG2 including second mode information to the first signal processing component 115 according to preset information. The second condition is, for example, that the rotational speed of the second transmission module 200 is higher than a second preset rotational speed and the torque is lower than a second preset torque.

[0113] Therefore, when the first transmission module 100 receives the second signal SG2 including the second mode information, the first signal processing component 115 and the first computing element 117 control the drive component 120 to drive the first transmission module 100 and the second transmission module 200 to move relative to each other in a second mode. For example, in the second mode, the drive component 120 reduces the output auxiliary power to reduce the rotational speed of the second transmission module 200.

[0114] In other embodiments, when the second signal processing component 215 determines that the first sensing signal SES1 meets a third condition based on preset information, the second signal processing component 215 outputs a second signal SG2 including a third mode information to the first signal processing component 115.

[0115] Next, when the first transmission module 100 receives the second signal SG2 including the third mode information, the first transmission module 100 outputs the first signal SG1 in a third mode. In this embodiment, the third condition is, for example, that the rotational speed of the second transmission module 200 is higher than a third preset rotational speed, and the third preset rotational speed may be greater than the first preset rotational speed and the second preset rotational speed, but is not limited thereto.

[0116] When the rotational speed of the second transmission module 200 is high (e.g., above 100 rpm, 500 rpm, or 5000 rpm, depending on the applied device or the distance between the first transmission module 100 and the second transmission module 200, etc.), signal transmission between the first transmission module 100 and the second transmission module 200 may be affected. Therefore, in the third mode, the first transmission module 100 increases the power, frequency, or extreme value of the output first signal SG1 to ensure that the second transmission module 200 can correctly receive the first signal SG1.

[0117] Similarly, when the second signal processing component 215 determines that the first sensing signal SES1 meets a fourth condition based on preset information, the second signal processing component 215 outputs a second signal SG2 including a fourth mode information to the first signal processing component 115.

[0118] When the first transmission module 100 receives the second signal SG2, which includes third mode information, the first transmission module 100 outputs the first signal SG1 in a fourth mode. In this embodiment, the fourth condition is, for example, that the rotational speed of the second transmission module 200 is lower than a fourth preset rotational speed, and the fourth preset rotational speed is lower than a third preset rotational speed, but it is not limited to this.

[0119] As the rotational speed of the second transmission module 200 decreases, the impact on signal transmission between the first transmission module 100 and the second transmission module 200 is reduced. Therefore, in the fourth mode, the first transmission module 100 can reduce the power, frequency, or extreme value of the output first signal SG1 to reduce the power consumption of the first transmission module 100.

[0120] In this context, the first signal SG1 is different from the second signal SG2. For example, in addition to the fact that the extreme value of the first signal SG1 is greater than the extreme value of the second signal SG2, the frequencies and / or powers of the first signal SG1 and the second signal SG2 may also be different.

[0121] It is also worth noting that the comparison between the aforementioned preset information and the sensing signals is performed by the second signal processing component 215, but is not limited thereto. In other embodiments, the second signal processing component 215 may also integrate the aforementioned multiple sensing signals into a second signal SG and transmit it to the first signal processing component 115, which then compares and judges the multiple sensing signals with the preset information and executes subsequent procedures.

[0122] Please refer to the following: Figure 4 . Figure 4 This is a functional block diagram of a wireless transmission system 10A according to another embodiment of the present disclosure. This embodiment is similar to the foregoing embodiment, except that the second transmission module 200 in this embodiment may further include a second power supply 213, and the second signal processing component 215 is configured to transmit the first electrical signal EC1 to the second power supply 213.

[0123] The second power source 213 is, for example, an electronic component such as a battery or a capacitor capable of storing electrical energy, but is not limited thereto. The second power source 213 is configured to output a third electrical signal EC3 to the first sensing component 221 so that the first sensing component 221 can operate normally. In addition, in this embodiment, the second transmission module 200 may also include a third sensing component 223.

[0124] Similarly, the second power supply 213 is configured to output a fourth electrical signal EC4 and a fifth electrical signal EC5 to the second sensing component 222 and the third sensing component 223 respectively, so that the second sensing component 222 and the third sensing component 223 can operate normally.

[0125] In this embodiment, the third sensing component 223 is configured to sense the power of the second power supply 213 and correspondingly output a third sensing signal SES3 to the second signal processing component 215, and the second signal processing component 215 is configured to monitor the power of the second power supply 213 according to the third sensing signal SES3.

[0126] In this embodiment, when the first transmission module 100 does not transmit the first signal SG1 to the second transmission module 200 (that is, when the wireless transmission system 10 is not in the startup mode), the maximum power capacity of the second power supply 213 of the second transmission module 200 is less than 200mAh.

[0127] In this embodiment, the second transmission module 200 may further include a safety component 230, electrically connected to the second power supply 213. When the first transmission module 100 fails to transmit the first signal SG1 to the second transmission module 200 for more than a first preset time, the second signal processing component 215 controls the safety component 230 to activate, causing the safety component 230 to release the power of the second power supply 213 to a safe value within a second preset time. The second signal processing component 215 is configured to monitor and determine whether the power of the second power supply 213 has reached the aforementioned safe value based on the third sensing signal SES3.

[0128] The safety component 230 may be, for example, a resistor, but is not limited thereto. The safety component 230 is configured to convert the electrical energy of the second power source 213 into heat energy. Furthermore, the first preset time may be less than 6 hours, the second preset time may be less than 1 hour, and the safety value may be defined as half of the maximum capacity of the second power source 213.

[0129] With this configuration, when the wireless transmission system 10A is placed outdoors or in a car and is not in use, the probability of the second power supply 213 causing danger can be reduced, thereby increasing the safety of the wireless transmission system 10A.

[0130] Please refer to the following: Figure 1 , Figure 5 and Figure 6 . Figure 5 For a wireless transmission system 10 according to an embodiment of the present disclosure along Figure 1 A top view of a portion of the structure when viewed from the first direction D1, and Figure 6 For a wireless transmission system 10 according to an embodiment of the present disclosure along Figure 1 The top view of a portion of the structure when viewed from the first direction D1.

[0131] like Figure 1As shown, the wireless transmission system 10 also includes a spacer 212 disposed between the first coil 111 and the second coil 211. In this embodiment, the spacer 212 is disposed on the second housing 202, but is not limited thereto. In other embodiments, the spacer 212 may also be disposed on the first housing 102.

[0132] Specifically, at least a portion of the spacer 212 is embedded within the first housing 102 or the second housing 202. For example, the spacer 212 is embedded in the inner wall of the first housing 102 or the second housing 202, and the spacer 212 may be made of metal.

[0133] In order to enable stable signal transmission between the first coil 111 and the second coil 211, in this embodiment, the frequency of the periodic first signal SG1 is greater than 1 MHz, and the frequency of the periodic second signal SG2 is greater than 1 MHz. For example, the first coil 111 and the second coil 211 can communicate using Near Field Communication (NFC) mode, and the frequencies of the first signal SG1 and the second signal SG2 can be 13.56 MHz, but are not limited thereto.

[0134] Furthermore, the spacer member 212 has multiple perforations, which are partially and evenly distributed on the spacer member 212. For example... Figure 5 As shown, when viewed along the winding axis 111X of the first coil 111, the boundary 1111 of the first coil 111 surrounds and defines a first area, and when viewed along the winding axis 111X of the first coil 111, the area of ​​the metal portion of the spacer 212 is less than half of the first area.

[0135] Similarly, such as Figure 6 As shown, when viewed along the winding axis 211X of the second coil 211, the boundary 2111 of the second coil 211 surrounds and defines a second area, and when viewed along the winding axis 211X of the second coil 211, the area of ​​the metal portion of the spacer 212 is less than half of the second area. The winding axis 211X is overlapped with the winding axis 111X.

[0136] To achieve the proportional relationship between the areas of the first area, the second area, and the metal portion of the spacer 212, the configuration of the aforementioned plurality of perforations is described below. For example... Figure 5 and Figure 6 As shown, the spacer 212 may define a first region 2121 and a second region 2122. The first region 2121 has an annular structure and a third area, and the second region 2122 also has an annular structure, surrounds the first region 2121 and has a fourth area.

[0137] The perforations on the spacer 212 may include multiple first perforations 2123 and multiple second perforations 2124, which are respectively disposed in the first region 2121 and the second region 2122. Furthermore, the ratio of the total area of ​​these first perforations 2123 to the third area is different from the ratio of the total area of ​​the second perforations 2124 to the fourth area. For example, the ratio of the total area of ​​these first perforations 2123 to the third area is greater than the ratio of the total area of ​​the second perforations 2124 to the fourth area.

[0138] Based on this configuration, the proportion of metal in the spacer 212 in the first region 2121 is different from the proportion of metal in the spacer 212 in the second region 2122. Specifically, the proportion of metal in the spacer 212 in the first region 2121 is less than the proportion of metal in the spacer 212 in the second region 2122.

[0139] Based on the aforementioned spacing member 212 and the perforation configuration, even if the spacing member 212 is made of metal, the first coil 111 and the second coil 211 can still transmit signals stably. Furthermore, based on the configuration of the spacing member 212, the overall structural strength of the second housing 202 can be increased to ensure that there will be no damage when the second transmission module 200 rotates at high speed.

[0140] It is worth noting that the dimensions of the first perforation 2123 and the second perforation 2124 are the same, and both are circular in shape, but this is not a limitation. In other embodiments, the dimensions of the first perforation 2123 and the second perforation 2124 may be different. Furthermore, since the spacer member 212 is partially embedded in the inner wall of the second housing 202, the aforementioned perforation may include a portion of the inner wall, meaning the perforation may be filled with a portion of the second housing 202 made of plastic material.

[0141] For example, please refer to Figure 7 . Figure 7 For a wireless transmission system 10 according to another embodiment of this disclosure along Figure 1 A top view of a portion of the structure when viewed from the first direction, D1. (See example...) Figure 7 As shown, in this embodiment, the first perforation 2123 and the second perforation 2124 can be fan-shaped structures, and the size of the first perforation 2123 is different from that of the second perforation 2124.

[0142] The size and shape of the first perforation 2123 and the second perforation 2124 are not limited to the aforementioned circular or fan-shaped shapes. Any size and shape that enables the first coil 111 and the second coil 211 to transmit signals stably are within the scope of this disclosure.

[0143] This disclosure provides a wireless transmission system 100, including a first transmission module 100 and a second transmission module 200. The second transmission module 200 is movably connected to the first transmission module 100. The first transmission module 100 is configured to transmit a first signal SG1 to a second coil 211 of the second transmission module 200 via a first coil 111. A second signal processing component 215 of the second transmission module 200 can convert the first signal SG1 into an electrical signal to provide power to one or more sensing components, enabling them to sense parameters such as the rotational speed or torque of the second transmission module 200.

[0144] After receiving the sensing signals from these sensing components, the second signal processing component 215 determines whether these sensing signals meet specific conditions based on preset information, such as low speed and high torque or high speed and low torque, and accordingly sends a second signal SG2 to the first transmission module 100 through the second coil 211. The first transmission module 100 controls a drive component 120 according to the second signal SG2 to change parameters such as the speed or torque of the second transmission module 200.

[0145] The wireless transmission system 10 disclosed herein can be applied to products such as electric bicycles or fishing reels, and can provide auxiliary power to assist the user according to the user's usage situation. Furthermore, since the coils and electronic components on the rotor (such as the second transmission module 200) can be powered or communicated without external wires, the problem of existing rotating modules tearing the wires during rotation can be avoided.
