Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] The following is combined Figure 1 and Figure 2 A circuit for a shared massage chair according to the present invention includes: The system includes a control module 100 and a communication module 200, wherein the control module 100 is connected to the communication module 200. The connection port module 300 includes at least two first connection ports 310 for connecting to a shared massage chair, and the control module 100 is connected to the connection port module 300. An audio multiplexing module 400 is provided, which is connected to the connection port module 300. The control module 100 and / or the communication module 200 are connected to the audio multiplexing module 400. The audio multiplexing module 400 is used to select the first connection port 310 and output an audio signal to the first connection port 310.

[0024] The connection port module 300 includes multiple first connection ports 310 for connecting to shared massage chairs. The control module 100 is connected to each of the first connection ports 310, enabling the control module 100 to control multiple shared massage chairs through the connection port module 300. A communication module 200 is connected to the control module 100 to enable network communication, allowing multiple shared massage chairs to share the same communication module and control module 200, thus achieving network control of each shared massage chair. An audio multiplexing module 400 is connected to the connection port module 300. The audio signal input to the audio multiplexing module 400 can come from the control module 100 and the communication module 200. The audio multiplexing module 400 selects a first connection port 310 for audio signal output, allowing selection of shared massage chairs to play audio, thus enabling multiple shared massage chairs to share audio processing functions.

[0025] In this way, multiple shared massage chairs can share the same communication module 200 for network control, eliminating the need for separate communication boxes for each shared massage chair, which helps reduce implementation costs. At the same time, the audio multiplexing module 400 enables audio playback control of multiple shared massage chairs, achieving the effect of audio processing multiplexing, which helps simplify the audio circuit of the shared massage chairs, further reducing implementation costs. Moreover, integrating the network communication and audio processing functions of multiple shared massage chairs into the same circuit facilitates maintenance.

[0026] In some embodiments of the present invention, the communication module 200 may include implementations of devices or circuit modules such as network cards and WIFI modules, for communicating with servers, cloud platforms, etc., to realize network communication functions. In some embodiments, the communication module 200 may be connected to a communication card. The control module 100 may include implementations of devices such as microcontrollers and embedded chips. In some embodiments, the communication module 200 may include an implementation of an ML307R chip, and the control module 100 may include an implementation of an STM32 chip.

[0027] In some embodiments of the present invention, when a user needs to use a shared massage chair, the user can send a usage request to the server via a mobile phone or other device by scanning a QR code or using a mini-program. The server responds to the usage request, determines the shared massage chair the user wants to use, and sends the identification information of the shared massage chair to the control module 100 through the communication module 200. The control module 100 determines the target shared massage chair based on the identification information, and then determines the corresponding first connection port 310 in the connection port module 300. The control module 100 controls the target shared massage chair to start through the first connection port 310. At the same time, the control module 100 or the communication module 200 outputs audio to the audio multiplexing module 400, and transmits it to the target shared massage chair through the same first connection port 310 to play the corresponding audio to guide the user.

[0028] Since the probability of multiple shared massage chairs being requested simultaneously is low, the audio processing function can be reused. However, if more than one shared massage chair is requested simultaneously, resulting in audio conflicts, time-division multiplexing can be used to process the audio signals. This involves queuing and buffering the audio signals, processing them one by one, and then transmitting them to the corresponding shared massage chair for playback.

[0029] It should be noted that the audio signal output through the first connection port 310 can be generated by the control module 100 and stored in the control module 100 in a pre-set manner, or it can be generated by the communication module 200 to obtain the latest audio through network communication, facilitating remote updates of the audio content to be played. Correspondingly, depending on the actual application requirements, either the control module 100 or the communication module 200 can be connected to the audio multiplexing module 400, or both the control module 100 and the communication module 200 can be connected to the audio multiplexing module 400.

[0030] It is understood that the circuit for a shared massage chair provided by the present invention may be located in a device or equipment outside the massage chair in some embodiments, and the device or equipment may be connected to multiple shared massage chairs respectively through the connection port module 300; in other embodiments, it may be located in a shared massage chair, which acts as the main control device and is connected to other shared massage chairs through the connection port module 300.

[0031] refer to Figure 1 In some embodiments of a circuit for a shared massage chair according to the present invention, the audio multiplexing module 400 includes a digital-to-analog converter unit 410, a power amplifier unit 420, and a selection enable unit 430. The number of power amplifier units 420 is equal to the number of the first connection ports 310 and they correspond one-to-one. The control module 100 and / or the communication module 200 are connected to the input terminal of the digital-to-analog converter unit 410. The output terminal of the digital-to-analog converter unit 410 is connected to the input terminal of the power amplifier unit 420. The enable unit is connected to the controlled terminal of the power amplifier unit 420. The control module 100 is connected to the selection enable unit 430 to control the start and stop of the power amplifier unit 420. The output terminal of the power amplifier unit 420 is connected to the corresponding first connection port 310.

[0032] The digital-to-analog converter 410 acquires audio digital signals from the control module 100 and the communication module 200, and then converts the audio into an analog audio signal suitable for playback by speakers and other devices through digital-to-analog conversion processing. The analog audio signal is transmitted to the power amplifier unit 420 for power amplification processing to form an analog audio signal with sufficient power to drive speakers and other devices to play audio. The first connection port 310 corresponds one-to-one with the power amplifier unit 420, and also corresponds one-to-one with the shared massage chair. Therefore, the power amplifier unit 420 and the shared massage chair also have a one-to-one correspondence. The control module 100, based on the target shared massage chair, selects the power amplifier unit 420 corresponding to the target shared massage chair to start for power amplification processing through the selection enable unit 430, while the power amplifier units 420 corresponding to other non-target shared massage chairs stop working. This ensures that the target shared massage chair plays audio, while the non-target shared massage chairs do not play audio, achieving the effect of selective playback.

[0033] In some embodiments of the present invention, the digital-to-analog conversion unit 410 may include implementations of devices or circuits such as a digital-to-analog conversion chip and a digital-to-analog conversion circuit; the power amplifier unit 420 may include implementations of devices or circuits such as a power amplifier chip and a power amplifier circuit. In some embodiments, the power amplifier unit 420 may include an implementation of an SD8002D chip.

[0034] refer to Figure 1 In some embodiments of a circuit for a shared massage chair according to the present invention, the audio multiplexing module 400 further includes at least two grouped operational amplifier units 440, the power amplifier unit 420 is grouped into power amplifier unit groups according to the number of operational amplifier units, the input terminal of the power amplifier unit group is connected to the output terminal of the corresponding operational amplifier unit, the output terminal of the digital-to-analog converter unit 410 is connected to the input terminal of the operational amplifier unit, and the control module 100 is connected to the controlled terminal of the operational amplifier unit.

[0035] The system is equipped with at least two group operational amplifier units 440. The audio analog signal output from the digital-to-analog converter unit 410 is transmitted to each group operational amplifier unit 440, and then the group operational amplifier unit 440 transmits it to the corresponding power amplifier unit 420. (Reference) Figure 1 The power amplifier units 420 are grouped according to the number of grouped operational amplifier units 440 to form power amplifier unit groups. The power amplifier units 420 in the power amplifier unit group are connected to the corresponding grouped operational amplifier units 440. For example, if there are 2 grouped operational amplifier units 440 and 12 power amplifier units 420, the power amplifier units 420 are divided into 2 groups, each group having 6 power amplifier units 420. The 2 grouped operational amplifier units 440 are connected to the 2 groups of power amplifier units, that is, each grouped operational amplifier unit 440 is connected to 6 power amplifier units 420.

[0036] The control module 100 controls the output direction of the audio analog signal by controlling the group operational amplifier unit 440, and then selects the target power amplifier unit 420 by combining the selection enable unit 430 to start the target power amplifier unit 420 for power amplification. In this way, based on the group control of the audio analog signal and combined with the enable control, the power amplifier unit 420 is selected. That is, the power amplifier unit 420 is selected not only by controlling the power amplifier unit 420 through the enable terminal, but also by controlling it in conjunction with the input direction of the audio analog signal. This simplifies the circuit structure of the selection enable unit 430.

[0037] In some embodiments of the present invention, the grouped operational amplifier unit 440 may be an implementation of devices or circuits such as operational amplifier chips or operational amplifier circuits.

[0038] refer to Figure 1 and Figure 3 In some embodiments of a circuit for a shared massage chair according to the present invention, the selection enable unit 430 includes a switching transistor 431 corresponding to the power amplifier unit 420, the switching transistor 431 being connected to the controlled terminal of the corresponding power amplifier unit 420, and the control module 100 being connected to the controlled terminal of the switching transistor 431.

[0039] The selection enable unit 430 includes a switch transistor 431 corresponding to each of the power amplifier units 420. Each power amplifier unit 420 is connected to a switch transistor 431 at its controlled terminal. The control module 100 controls the switching transistors 431 to change the voltage at the controlled terminal of the power amplifier unit 420, thereby controlling the power amplifier unit 420 to start or stop working.

[0040] In some embodiments of the present invention, the switching transistor 431 may be a transistor device with switching function, such as a triode or a field-effect transistor.

[0041] Typically, to control the start and stop of each power amplifier unit 420, the control module 100 needs to set pins corresponding one-to-one with each power amplifier unit 420. This means the number of pins occupied by the control module 100 is equal to the number of power amplifier units 420, leading to excessive pin usage. In this invention, to achieve shared use of the same communication module 200, the control module 100 needs to control multiple shared massage chairs; therefore, the pin resources of the control module 100 need to be fully utilized.

[0042] To address the aforementioned issues, in some embodiments of a circuit for a shared massage chair according to the present invention, the control module 100 is provided with power amplifier control pins, the number of which is equal to the number of power amplifier units 420 in the power amplifier unit group, and the power amplifier control pins are respectively connected to the controlled terminals of the switching transistors 431 corresponding to the power amplifier units 420 in each power amplifier unit group.

[0043] For each power amplifier unit group, the power amplifier control pin corresponds one-to-one with the power amplifier unit 420 in the group, and then the power amplifier control pin is connected to the controlled terminal of the corresponding switching transistor 431. That is, the power amplifier control pin is connected to the controlled terminal of the switching transistor 431 corresponding to one power amplifier unit 420 in each group. The number of switching transistors 431 connected to the power amplifier control pin is equal to the number of power amplifier unit groups.

[0044] For example, there are power amplifier unit group A and power amplifier unit group B. Power amplifier unit group A includes power amplifier unit a1, power amplifier unit b1 and power amplifier unit c1, and power amplifier unit group B includes power amplifier unit a2, power amplifier unit b2 and power amplifier unit c2. Then there are 3 power amplifier control pins. The first power amplifier control pin is connected to the controlled terminal of the corresponding switch transistor 431 of power amplifier unit a1 and power amplifier unit a2, respectively. The second power amplifier control pin is connected to the controlled terminal of the corresponding switch transistor 431 of power amplifier unit b1 and power amplifier unit b2, respectively. The third power amplifier control pin is connected to the controlled terminal of the corresponding switch transistor 431 of power amplifier unit c1 and power amplifier unit c2, respectively.

[0045] When selecting the target power amplifier unit 420, the control unit adjusts the power amplifier control pin in conjunction with the control group operational amplifier unit 440 to achieve the effect of selecting the target power amplifier unit 420. Based on the above example, the control unit adjusts the level of the first power amplifier control pin, causing power amplifier units a1 and a2 to start. At the same time, it controls the group operational amplifier unit 440 corresponding to power amplifier unit group A, so that the audio analog signal is transmitted to power amplifier unit group A. Then, power amplifier unit a1, which belongs to power amplifier unit group A, receives the audio analog signal input, while power amplifier unit a2, which belongs to power amplifier unit group B, does not receive the audio analog signal. Therefore, only power amplifier unit a1 amplifies the audio analog signal and outputs audio through the corresponding first connection port 310, thus achieving the effect of the control module 100 selecting power amplifier unit a1 as the target operational amplifier unit 440.

[0046] Therefore, the control module 100 does not need to have the same number of power amplifier control pins as the total number of power amplifier units 420, which helps to reduce the number of pins occupied by the control module 100, making it easier to control more shared massage chairs and further reducing implementation costs.

[0047] It is understandable that although the group operational amplifier unit 440 also occupies pins of the control module 100, the number of pins used by the control module 100 to control the group operational amplifier unit 440, plus the number of power amplifier control pins, is still less than the total number of power amplifier units 420. In the example above, there are 6 power amplifier units 420, which typically require 6 pins of the control module 100. However, with the structure of this invention, there are 2 groups of power amplifier units, i.e., 2 group operational amplifier units 440, occupying 2 pins of the control module 100. Combined with the 3 power amplifier control pins, this totals 5 pins occupied by the control module 100, less than the conventional 6. This achieves the effect of reducing the number of pins occupied by the control module 100. Furthermore, as the number of shared massage chairs controlled increases, i.e., the total number of power amplifier units 420 increases, the reduction in the number of pins occupied by the control module 100 becomes even more significant.

[0048] Understandably, when the number of power amplifier units 420 included in a power amplifier unit group is different, for example, there are 2 grouped operational amplifier units 440 and 11 power amplifier units 420, it is not possible to achieve completely even grouping. Instead, it is divided into two power amplifier unit groups, one with 6 power amplifier units 420 and the other with 5 power amplifier units 420. In this case, the number of power amplifier control pins of the control module 100 is equal to the number of the most powerful power amplifier units 420 in the power amplifier unit group, that is, the number of power amplifier control pins is 6.

[0049] In some embodiments of the present invention, the enable unit 430 may also be an implementation that includes a decoder. The control module 100 is connected to the controlled terminals of each power amplifier unit 420 through the decoder. The decoder can further reduce the number of pins occupied by the control module 100.

[0050] refer to Figure 2 and Figure 4 In some embodiments of a circuit for a shared massage chair according to the present invention, the first connection port 310 includes a start control pin, a seat occupancy detection pin, a charging control pin, an online detection pin, and an audio pin. The start control pin, the seat occupancy detection pin, the charging control pin, and the online detection pin are all connected to the control module 100, and the audio pin is connected to the audio multiplexing module 400.

[0051] Each first connection port 310 includes a start control pin for controlling the start and stop of the shared massage chair, a seat occupancy detection pin for obtaining the occupancy status of the shared massage chair, a charging control pin for controlling the charging function of the shared massage chair, an online detection pin for obtaining the online status of the shared massage chair, and an audio pin for controlling the audio playback device on the shared massage chair. Thus, the first connection port 310 can realize the control and status detection of various functions of the shared massage chair, and meet the needs of control and status detection.

[0052] refer to Figure 4 In some embodiments of a circuit for a shared massage chair according to the present invention, the first connection port 310 is an RJ45 port.

[0053] The use of an RJ45 port facilitates connection using a common port architecture. It is important to emphasize that this invention redefines the pinout of the RJ45 port; that is, it does not adopt the standard RJ45 port pinout. (Refer to...) Figure 4 The RJ45 port pins are defined as follows: AMY LEVEL (start control), SEAT DET (seat occupancy detection), CHARGE LEVEL (charging control), ONLINE DET (online detection), and audio pins (SPK+ and SPK-). The AMY LEVEL, SEAT DET, and ONLINE DET pins are all single and connected to the control module 100. The audio pins, required to drive the speakers, are two and connected to the audio multiplexing module 400. This utilizes the RJ45 port structure to facilitate physical connection operations, making implementation more convenient, while the redefined pin settings meet the control and status detection requirements of the shared massage chair.

[0054] The control module connects to multiple shared massage chairs via multiple first connection ports 310, forming a star connection structure. In some embodiments of the present invention, a 485 serial port can also be used as the first connection port 310 to achieve connection with multiple shared massage chairs in a star connection structure. It should be emphasized that using an RJ45 port as the first connection port 310, compared to using a 485 serial port as the first connection port 310, offers better communication quality and stability due to signal reflection issues in the 485 serial port star connection structure, and is also more convenient to implement. Therefore, the present invention redefines the functions of each pin of the RJ45 port to meet the needs of multiple shared massage chair scenarios and ensure communication reliability.

[0055] refer to Figure 2 The present invention also provides a shared massage chair, including a chair body, wherein the chair body is provided with a massage component 510, an audio playback component 520 and a second connection port 530, the second connection port 530 being connected to the controlled end of the massage component 510 and the audio playback component 520 respectively, and the second connection port 530 being used to connect to the first connection port 310 in the circuit for the shared massage chair described above.

[0056] The connection port module 300 includes multiple first connection ports 310 for connecting to shared massage chairs. The control module 100 is connected to each of the first connection ports 310, enabling the control module 100 to control multiple shared massage chairs through the connection port module 300. Each chair body has a second connection port 530 corresponding to a first connection port 310. By connecting the second connection port 530 to the first connection port 310, under the networking function of the communication module 200, the control module 100 can obtain instructions from servers and other devices. Based on these instructions, the control module 100 controls the corresponding shared massage chair through the first connection port 310, allowing multiple shared massage chairs to share the same communication module and control module 200. The audio multiplexing module 400 selects the first connection port 310 for audio signal output, and then transmits the audio signal through the second connection port 530 to the audio playback component 520 for playback, achieving the effect of selecting which shared massage chair to play audio, thus enabling multiple shared massage chairs to reuse audio processing functions.

[0057] Therefore, the shared massage chair is equipped with a second connection port 530 corresponding to the first connection port 310. Multiple shared massage chairs share the same communication module 200 to achieve network control, eliminating the need to configure a separate communication box for each shared massage chair, which helps reduce implementation costs. At the same time, the audio multiplexing module 400 realizes audio playback control for multiple shared massage chairs, achieving the effect of audio processing multiplexing, which helps to simplify the audio circuit of the shared massage chair, further reducing implementation costs. Moreover, integrating the network communication and audio processing functions of multiple shared massage chairs into the same circuit facilitates maintenance.

[0058] refer to Figure 2 In some embodiments of the shared massage chair of the present invention, it further includes a seat occupancy detection module 540, a charging module 550 and a main control module 560, all of which are disposed on the chair body. The controlled end of the seat occupancy detection module 540, the controlled end of the charging module 550 and the main control module 560 are all connected to the second connection port 530.

[0059] A seat occupancy detection module 540 is installed on the chair to detect whether a user is occupying the chair, generating a seat occupancy detection signal that is fed back to the control module 100 via the second connection port 530. A charging module 550 is also installed on the chair, allowing users to charge their mobile phones and other devices while using the shared massage chair, improving the user experience. The main control module 560 performs online monitoring with the control module 100 via the second connection port 530. This means the control module 100 can detect whether the main control module 560 on the chair is working properly, thus promptly determining whether the shared massage chair is functioning correctly. The main control module 560 can connect to the massage component 510, audio playback component 520, and charging module 550 to control their operating status, such as switching the working mode of the massage component 510 and adjusting the playback volume of the audio playback component 520.

[0060] It is understandable that the second connection port 530 corresponds to the first connection port 310. When the first connection port 310 includes a start control pin, a seat occupancy detection pin, a charging control pin, an online detection pin, and an audio pin, the second connection port 530 also includes corresponding start control pins, seat occupancy detection pins, charging control pins, online detection pins, and audio pins. The controlled end of the massage component 510 is connected to the start control pin, the seat occupancy detection module 540 is connected to the seat occupancy detection pin, the controlled end of the charging module 550 is connected to the charging control pin, the main control module 560 is connected to the online detection pin, and the audio playback component 520 is connected to the audio pin. When the first connection port 310 is an RJ45 port, the second connection port 530 is also an RJ45 port.

[0061] In some embodiments of the present invention, the seat occupancy detection module 540 may include devices such as pressure sensors and limit switches. When a user sits on the chair, the pressure sensor, limit switch, etc., generate an electrical signal and transmit it to the control module 100 through the second connection port 530 and the first connection port 310, so that the control module 100 knows that the corresponding shared massage chair is occupied. The charging module 550 may include a charging circuit and a charging port. The controlled end of the charging circuit is connected to the second connection port 530, allowing the control module 100 to control the start and stop of the charging circuit. The charging port is connected to the charging circuit to obtain electrical energy to charge the connected device. The main control module 560 may include devices such as a microcontroller and embedded chips. The main control module 560 on the chair changes the voltage level of its pins to allow the control module 100 to know whether the main control module 560 is online, and thus whether the main control module 560 is faulty.

[0062] refer to Figure 2The present invention also provides a massage chair system, including the circuit for a shared massage chair described above, and at least two shared massage chairs described above, wherein the first connection port 310 and the second connection port 530 are connected in a one-to-one correspondence.

[0063] The connection port module 300 includes multiple first connection ports 310 for connecting to shared massage chairs. The control module 100 is connected to each of the first connection ports 310, and each first connection port 310 is connected to a corresponding second connection port 530 on the shared massage chair, enabling the control module 100 to control multiple shared massage chairs through the connection port module 300. A communication module 200 is connected to the control module 100 to enable network communication, allowing multiple shared massage chairs to share the same communication module and control module 200, thus achieving network control of each shared massage chair. An audio multiplexing module 400 is connected to the connection port module 300. The audio signal input to the audio multiplexing module 400 can come from the control module 100 and the communication module 200. The audio multiplexing module 400 selects a first connection port 310 for audio signal output, allowing selection of shared massage chairs to play audio, thus enabling multiple shared massage chairs to share audio processing functions.

[0064] In this way, multiple shared massage chairs can share the same communication module 200 for network control, eliminating the need for separate communication boxes for each shared massage chair, which helps reduce implementation costs. At the same time, the audio multiplexing module 400 enables audio playback control of multiple shared massage chairs, achieving the effect of audio processing multiplexing, which helps simplify the audio circuit of the shared massage chairs, further reducing implementation costs. Moreover, integrating the network communication and audio processing functions of multiple shared massage chairs into the same circuit facilitates maintenance.
