1 is a functional block diagram of a first button body of a smart buckle according to an embodiment of the present invention. 2 is a circuit diagram of a first button body of a smart buckle according to another embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 . The first button body 11 in FIG. 1 includes a first connecting unit 111, a voltage waveform generating unit 112, a converting unit T1, a battery unit BP1, a voltage control switch unit 114, and a load detecting unit 116.

The first connecting unit 111 includes a first contact P1, a second contact P2, and a third contact P3.

In practice, the voltage waveform generating unit 112 is coupled to the first contact P1, the converting unit T1, and the first processing unit 110. The conversion unit T1 is coupled to the voltage waveform generation unit 112, the voltage control switch unit 114, the first processing unit 110, and the battery unit BP1. The voltage control switch unit 114 is coupled to the first contact P1, the conversion unit T1, and the first processing unit 110. The load detecting unit 116 is coupled to the second contact P2, the first current protection switch PS1, and the first processing unit 110. The first current protection switch PS1 is coupled to the second contact P2, the load detecting unit 116, the first processing unit 110, and the first detecting power Block RD1.

The first voltage stabilizing unit LD1 is coupled to the battery unit BP1, the converting unit T1, and the first processing unit 110.

Further, the first button body 11 is detachably coupled to the second button body 12. That is, the first connecting unit 111 of the first button body 11 is detachably coupled with the second connecting unit 122 of the second button body 12. The first contact P1 is a contact for transmitting a voltage. The second contact P2 is a contact for transmitting current. The third contact P3 is a contact for transmitting data. Therefore, when the second button body 12 is combined with the first button body 11, the application module AP of the second button body 12 can operate; or when the application module AP of the second button body 12 is a battery module, the battery The module can supply power to the battery unit BP1 of the first button body 11. In other embodiments, the first connection unit 111 may also have no third contact P3. That is to say, the first button body 11 realizes simplex or full-duplex transmission of power, data, etc. through two lines.

Next, the voltage waveform generating unit 112 is, for example, a circuit for generating a DC pulse signal. The DC pulse signal is used to inquire about the identity, type and demand of the second button body 12. The DC pulse signal is, for example, a square wave signal of 4.3 volts to 5 volts. That is, the first button body 11 transmits the DC pulse signal generated by the voltage waveform generating unit 112 to identify the identity, type, and demand of the second button body 12.

For example, there are two second button bodies 12, the application module AP of the first second button body 12 is a touch button or a voice recognition controller, and the application module AP of the second second button body 12 is Bluetooth. music player. The touch button or voice recognition controller of the first second button body 12 can be used to control the playing mode of the Bluetooth music player of the second second button body 12, such as the previous song, the next song, the shuttle Forward or backward, volume, and other features. The touch button or the voice recognition controller requires the first button body 11 to provide power requirements. When the first button body 11 is combined with the second button body 12, the voltage waveform generating unit 112 outputs a DC pulse signal to inquire about the identity, type, and demand of the second button body 12. The second button body 12 transmits a reply signal to the first button body 11, so that the first processing unit 110 of the first button body 11 knows that the second button body 12 is a touch button. Or voice recognition controller. Therefore, the first button body 11 is transmitted through the first connecting unit 111 to supply power to the second button body 12.

When the touch button of the first second button body 12 is pressed or a voice command is issued, the first second button body 12 transmits the button data or the voice command data to the first button body 11, and the first button body 11 After reading the data, the button data or voice command data is transmitted to the Bluetooth music player of the second second button body 12, and the second second button body 12 changes the current playing state according to the button data.

In addition, when the application module AP of the second button body 12 is a battery module. The battery module stores electrical energy. When the first button body 11 is combined with the second button body 12, the voltage waveform generating unit 112 outputs a DC pulse signal to inquire about the identity, type, and demand of the second button body 12. The second button body 12 transmits a reply signal to the first button body 11, so that the first processing unit 110 knows that the second button body 12 is a battery module. Therefore, the second button body 12 is transmitted through the first connecting unit 111 to supply power to the first button body 11.

Briefly, when the first button body 11 is combined with the second button body 12, the voltage waveform generating unit 112 outputs a DC pulse signal to inquire about the identity, type, and demand of the second button body 12. The first processing unit 110 knows the identity, type, and requirements of the second button body 12 according to the reply signal. The second button body 12 is an application module AP having "power supply to the first button body 11" or an application module AP having "power supply to the first button body 11".

Next, the voltage control switch unit 114 is realized by, for example, "a combination of at least one diode, at least one transistor, and at least one resistor." The voltage controlled switch unit 114 is one or more switches that are controlled by the first processing unit 110. That is, the first processing unit 110 can control the on or off of the voltage control switch unit 114.

The first contact P1, the voltage waveform generating unit 112, and the converting unit T1 form a first path. The first contact P1, the voltage control switch unit 114 and the conversion unit T1 form a second path. The first path is a path for outputting power to the second button body 12. The second path is a path for receiving power of the second button body 12. In other words, the power of the first button body 11 is transmitted from the first path to the second button body. 12; or the power of the second button body 12 is transmitted from the second path to the first button body 11.

The load detection unit 116 is configured to detect an external load. The load detecting unit 116 is realized by, for example, "a combination of a transistor and at least one resistor." When the second button body 12 is not combined with the first button body 11, the first current protection switch PS1 is in an off state, and the load detection unit 116 is in a waiting state. That is to say, when the first button body 11 is not coupled to the second button body 12, the second contact point P2 is in an open state, and the load detecting unit 116 is in a detection waiting state. In addition, the load detecting unit 116 is configured to detect whether the load of the second button body 12 is combined with the first button body 11 or whether the second button body 12 is away from the first button body 11.

The first processing unit 110 controls the first current protection switch PS1 to be turned on according to the first detection signal, wherein the current flows from the second contact point P2 through the first current protection switch PS1 and the first detection resistor RD1, the first reading unit 118 reads "the voltage change generated by the current flowing through the first detecting resistor RD1, thereby reading the data transmitted by the second button body 12.

That is to say, when the first button body 11 is combined with the second button body 12, the second contact point P2 has a voltage at one end, so that the load detecting unit 116 is turned on. Therefore, the first processing unit 110 learns the message "the first button body 11 is combined with the second button body 12" and turns on the first current protection switch PS1. Therefore, the current flows from the second contact P2 and passes through the first current protection switch PS1 and the first detection resistor RD1.

It is worth mentioning that the first reading unit 118 is implemented, for example, by a comparator or an operational amplifier. The first reading unit 118 can read the external signal and can be used as a current limiting protector, a circuit breaker or a short circuit protector. For example, the first reading unit 118 can read the voltage change of the first detecting resistor RD1, and transmit the first read signal of the voltage change to the first processing unit 110, whereby the first processing unit 110 The first read signal having the voltage change is used to identify the identity, type, and demand of the second button body 12.

The first reading unit 118 has a first preset current value. When the current flowing through the first detecting resistor RD1 is greater than the first preset current value, such as an overcurrent, the first reading unit 118 outputs a first A read signal is sent to the first processing unit 110. The first processing unit 110 controls the on state and the on state of the first current protection switch PS1 according to the first read signal, or turns off the first current protection switch PS1.

It is worth mentioning that, in some applications, the first reading unit 118 can also be replaced by an analog digital conversion function module built in the first processing unit 110. That is, the current flowing through the first detecting resistor RD1 is directly read by the first reading unit 118, and the first processing unit 110 can achieve all the functions of the first reading unit 118.

Further, the battery unit BP1 is realized by, for example, a rechargeable battery such as a nickel-zinc battery, a nickel-iron battery, or a lithium battery. The conversion unit T1 is realized by, for example, one or a combination of a boosting circuit, a step-down circuit, a buck-boost circuit, and a charging circuit, thereby providing different voltages, such as a voltage of 3V to 15V and a current of up to 3A. . The first voltage stabilizing unit LD1 is, for example, a linear regulator (LDO, Low Dropout Linear Regulator).

In other embodiments, those skilled in the art can freely design to omit "one or a combination of battery unit BP1, conversion unit T1, voltage control switch unit 114". For example, if the first button body 11 does not have the battery unit BP1, the battery module of the second button body 12 supplies power to the first button body 11; or the first button body 11 does not have the voltage control switch unit 114, The first button body 11 passes through the first path to provide power to the second button body 12; or the battery unit BP1 is in a replaceable form.

In addition, the first processing unit 110 can also be coupled to, for example, a Bluetooth communicator, a GPS communicator, a mobile phone, an infrared communicator, a radio frequency communicator, or other application modules.
