Description

Technical Field

[0001] The utility model relates to the technical field of sofa controllers, in particular to a sofa switch application circuit with a USB fast charging function and a panel connector thereof. Background Art

[0002] With the continuous improvement of people's living standards and the continuous development of science and technology, people's pursuit of the function of sofas has gradually shifted from the traditional comfort to the multi-functional integrated intelligent direction. For example, some sofas now have added electric adjustment functions, which can be adjusted to different postures through built-in telescopic motors. This type of sofa has been favored by many consumers in the market.

[0003] However, this type of sofa has the following defects:

[0004] 1. The electric adjustment circuit of this type of sofa does not have a charging function:

[0005] A. The electric adjustment circuit of this type of sofa is independent. If an additional independent charging circuit is required, the circuit connection of the sofa will be complicated;

[0006] B. At the same time, in the electric adjustment circuit, the power supply of the motor comes from the delivered power adapter. The power adapter is matched with a power supply of the same power according to the number of motors, such as 60W / 90W or higher power. However, when the user is using the sofa, he does not need to adjust the posture all the time. At this time, the power adapter is idle most of the time, which leads to the comprehensive utilization rate of the power adapter.

[0007] Second, further, the control panel connector has the following defects:

[0008] If this type of sofa has a charging function, then the control panel of the control panel connector must be integrated with the charging circuit, and a separate charging cable must be used to connect to the power supply. This will result in: A. The space structure of the control panel is bloated, which has the defect of unsightly appearance; B. It may get hot when charging, which has the defect of poor touch experience; C. When performing subsequent repairs and replacements and adding posture adjustment functions, the charging circuit in the control panel needs to be disassembled and assembled at the same time, which is inconvenient to disassemble and assemble and inconvenient to design.

When the user presses the motor reset button CS104, the motor reset interface transmits a signal to the reset signal ports of the seat motor and / or the waist motor and / or the headrest motor, thereby resetting the seat motor and / or the waist motor and / or the headrest motor.)

(Among them, Figure 3 This is the circuit diagram of the charging interface. Figure 4 This is the circuit diagram of the USBA power management module. Figure 5 This is the circuit diagram of the TYPEC power management module. Figure 7 This is the circuit diagram of the charging terminal. Figure 3 , Figure 4 , Figure 5 and Figure 7 There is a corresponding relationship of circuit connection between them. )

[0066] The charging interface CS12 includes a USBA charging port CS121 and / or a TYPEC charging port CS122. The charging docking terminal CS32 corresponds to the charging interface CS12. The charging docking terminal CS32 includes a USBA power supply interface and / or a TYPEC power supply interface.

[0067] The charging unit corresponds to the charging interface CS12 and includes a USBA power management module CS21 connected between the USBA charging interface CS121 and the USBA power supply interface and / or a TYPEC power management module CS22 connected between the TYPEC charging interface CS122 and the TYPEC power supply interface.

At the same time, the charging docking terminal CS32 integrates the USBA power supply interface of the USBA power management module CS21 and / or the TYPEC power supply interface connected to the TYPEC power management module CS22 into a connection connector, which is connected to the power adapter, and each signal line of the USBA power supply interface and the TYPEC power supply interface of the inner core of the connection connector is connected in parallel with an ESD diode, which prevents electrostatic discharge damage.

[0069] The functions of the charging interface CS12 of the control switch unit CS1, the charging unit, the socket between the charging interface CS12 and the charging unit, and the charging connection terminal CS32 are:

[0070] 1. Charging port CS12 is used by users to charge via USBA charging port CS121 and / or TYPEC charging port CS122;

[0071] 2. The socket between the charging interface CS12 and the charging unit enables the charging interface CS12 and the charging unit to be electrically connected;

Through the charging docking terminal CS32, the power adapter supplies power to the USBA power management module CS21 and / or the TYPEC power management module CS22.

[0074] The third part: MCU delay control circuit such as Figure 8 As shown ( Figure 8 This is the circuit diagram of the MCU delay control circuit. The input and Figure 6 The output of the circuit signal transmission is related to Figure 4 , Figure 5 related),

[0075] An MCU delay control circuit is connected between the motor connection terminal CS31 and the charging unit. The MCU extension control circuit includes a detection circuit CS41 and a charging delay control circuit CS42. The detection circuit CS41 has a detection branch CS411 connected in parallel to the seat motor control interface CS311 and / or the waist motor control interface CS312 and / or the headrest motor control interface CS313. The charging delay control circuit CS42 includes a detection signal (such as a detection signal) for receiving the detection branch CS411. Figure 8 The USBA power management module CS21 has a USBA switch chip CS211, the TYPEC power management module CS22 has a step-down switch chip CS221, and the second trigger circuit CS422 is used to receive the trigger signal of the first trigger circuit CS421 (such as the EN signal), the second trigger circuit CS422 connected to the first trigger circuit CS421 and the timing chip CS423 connected to the second trigger circuit CS422. Figure 8 The timing chip CS423 is used to receive the trigger signal of the second trigger circuit CS422 (such as the pull-down signal of the drain electrode D of the MOSFET tube Q1 in the first trigger circuit CS421). Figure 8 The output signal after timing is sent to the EN end of the USBA switch chip CS211 of the USBA power management module CS21 (the output signal after timing is as follows Figure 8 EN_OUT1 signal), EN end of the buck switch chip CS221 of the TYPEC power management module CS22 (the output signal after the timing is as follows Figure 8 EN1 signal).

[0076] The function of the above-mentioned MCU delay control circuit is to detect the action of the seat motor and / or the lumbar motor and / or the headrest motor. When the seat motor and / or the lumbar motor and / or the headrest motor are about to act, the power supply of the USBA power management module CS21 and the TYPEC power management module CS22 is first suspended to ensure sufficient power for driving the seat motor and / or the lumbar motor and / or the headrest motor. Then after a certain timing time (controlled by the timing chip CS423), the USBA power management module CS21 and the TYPEC power management module CS22 resume power supply.

[0077] The above-mentioned sofa switch application circuit with USB fast charging function combines the sofa control function and the charging function, and has the following advantages: first, there is no need to make two separately powered and separately connected circuits, and the circuit connection is simpler; second, the sofa control circuit can be connected to the power adapter of the sofa at one time, so that the comprehensive utilization rate of the power adapter on the sofa is higher; third, if a TYPEC charging port CS122 is set, the TYPEC charging port CS122 supports a maximum of 45W fast charging based on USB PD technology; fourth, through the motor reset button CS104, one-button restoration can be achieved, which is easy to use; fifth, through the MCU delay control circuit, it has an interrupt charging function to ensure sufficient power for driving the seat motor and / or the waist motor and / or the headrest motor.

[0078] Second, see Fig. 9 A panel connector includes a control panel SS11, a first cable SS12 installed at one end of the control panel SS11, a charging box SS21 installed at one end of the first cable SS12, a second cable SS22 installed at one end of the charging box SS21, and a sofa switch application circuit with USB fast charging function as described in the first aspect, wherein the control switch unit CS1 is installed on the control panel SS11, the first wire is installed inside the first cable SS12, the charging unit is installed inside the charging box SS21, and the second wire is installed inside the second cable SS22. Specifically, the sofa button CS10 and the charging interface CS12 of the control switch unit CS1 are installed on the outer surface of the control panel SS11, and the motor control circuit CS11 of the control switch unit CS1 is installed inside the control panel SS11.

[0079] At the same time, the motor connection terminal CS31 and the charging connection terminal CS32 are just two circuit structures summarized according to the circuit function classification, wherein the motor connection terminal CS31 has a seat motor control interface CS311 and / or a waist motor control interface CS312 and / or a headrest motor control interface, but on the control panel connector (physical structure), the second cable can be actually connected according to the actual design requirements of the sofa or the customer's power connection requirements, wherein such wiring methods are, for example, the following types (note: the following types are only to explain the logic of the wiring type, and do not mean that the wiring methods only cover the following types):

[0080] The first wiring type: the second cable is a whole line, one end of which has a plug, the plug integrates the motor connection terminal CS31 and the charging connection terminal CS32, the power adapter, the seat motor and / or the waist motor and / or the headrest motor are integrated into another plug, and the other plug is connected to the above plug;

[0081] The second wiring type: The second cable consists of two complete wires, which are further divided into two principles;

[0082] The first principle is to connect according to the proximity principle (such as Fig. 9 As shown), the first whole line on the left has a left plug, which is connected to the headrest motor closest to it, and the second whole line on the right has a right plug, and the power adapter, the lumbar motor and the seat motor are integrated into another plug, and the other plug is connected to the above right plug;

[0083] The second principle is to connect according to the functional principle. The first complete line on the left has a left plug, and the charging connection terminal CS32 is installed on the left plug. The left plug is connected to the power adapter. The second complete line on the right has a right plug, and the motor connection terminal CS31 is installed on the right plug. The seat motor, lumbar motor and headrest motor are integrated into another plug, and the other plug is connected to the above-mentioned right plug.

[0084] The third wiring type: The second cable is three whole lines, similar to the second wiring type, which is further divided into two principles; the first principle is to connect according to the proximity principle, and two lines close to two of the motors are led out separately, and the others are integrated together; the second principle is to connect according to the proximity principle and the function principle, and one line close to one of the motors is led out separately, the charging function is led out separately, and the others are integrated together.

[0085] The fourth connection type: the second cable is four complete wires, each of which has a plug, and the four plugs correspond to the power adapter, the seat motor and / or the lumbar motor and / or the headrest motor respectively.

[0086] The panel connector is provided with an operating switch unit on its operating panel for users to adjust the posture or charge. At the same time, the charging box SS21 equipped with the charging unit is separated from the control panel SS11. The modular separation design of the two has the following advantages: first, the spatial structure of the control panel SS11 is smaller, which occupies less of the outer side of the sofa, and has a beautiful appearance without affecting the user's touch; second, when charging, the heating of the charging box SS21 will not cause the control panel SS11 to heat up, which will not affect the user's touch; third, when the sofa button CS10 of the control panel SS11 needs to be repaired or replaced, only the charging box SS21 needs to be replaced. The control panel SS11 needs to be removed separately and repaired separately (the specific operation method is: disassemble the charging box SS21, unplug all the connection points between the charging box SS21 and the control panel SS11, and take away the control panel SS11 and the first cable SS12 together), which is convenient for maintenance. Alternatively, when it is necessary to add or reduce the function of the sofa button CS10 of the control panel SS11, the sofa button CS10 and the motor control circuit CS11 of the operation panel can be directly redesigned without adjusting the circuit of the charging unit.
