Furthermore, the terms "first," "second," and "third," etc. are used to distinguish between different objects and are not used to describe a particular order.
The terms to which the present invention relates will be explained first:

The standby time of the terminal is concerned by users rapidly, a standby battery is added in the terminal in order to increase the standby time of the terminal, when the electric quantity of a main battery of the terminal is exhausted, the standby battery can be switched to, and the standby battery continuously supplies power to the terminal.
In the prior art, when a terminal comprises a main battery and an auxiliary battery, the power supply of the terminal can be controlled by software to switch between the main battery and the auxiliary battery.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The terminal can be a mobile phone, a tablet computer, an MP4 player terminal, a learning machine, a point reading machine, an electronic dictionary or a vehicle-mounted terminal and the like.
Referring to fig. 1, the terminal includes a main board 1, and a main battery 2, a backup battery 4, and a change-over switch 3 are mounted on the main board 1, wherein the main battery 2 is a detachable battery. The backup battery 4 may be a detachable battery or a non-detachable battery, which is not limited in this embodiment.
In the embodiment of the present invention, the main battery 2 and the backup battery 4 are both power energy storage tools of the terminal, wherein the main battery 2 and the backup battery 4 may be lithium batteries or nickel-metal hydride batteries, or other types of batteries. The main battery 2 and the backup battery 4 are both connected to the changeover switch 3.
Referring to fig. 2 and 3, the switch 3 includes a first input terminal 32, a second input terminal 33, an enable terminal 31, and an output terminal 34, and the output terminal 34 of the switch 3 is switched between the first input terminal 32 and the second input terminal 33. The main battery 2 comprises a power pin 21 and a state pin 22, wherein the state pin 22 of the main battery 2 is connected with an enable terminal 31 of the switch 3, the power pin 21 is connected with the motherboard 1, the height of a first part of the motherboard 1 connected with the power pin 21 is smaller than that of a second part of the state pin 22, the state pin 22 is connected with the enable terminal 31 of the switch 3, and the power pin 21 of the main battery 2 is connected with a first input terminal 32 of the switch 3 through the first part.
The status pin 22 of the main battery 2 is connected to the enable terminal 31 of the switch 3, the enable signal generated by the enable terminal 31 can be represented by 0 and 1, and the enable signal of the enable terminal 31 is related to the signal of the status pin 22, for example, when the main battery 2 is in place, the status pin 22 of the main battery 2 is normally connected to the enable terminal 31 of the switch circuit 31, and the enable signal of the enable terminal 31 in this state can be represented by 1. When the main battery 2 is not in place (for example, after being detached), the state pin 22 of the main battery 2 is disconnected from the enable terminal 31 of the switching circuit 31, and the enable signal of the enable terminal 31 in this state can be represented by 0.
The backup battery 4 is connected to the second input terminal 32 of the switch 3 through the switch circuit 5, the output terminal 34 of the switch 3 is connected to the control terminal of the switch circuit 5, and the switch circuit 5 is used for controlling the switch circuit 5 to be turned on or off according to a signal of the control terminal.
The backup battery 4 is generally used to maintain information such as system configuration, date and time in a special memory area of the terminal, and therefore, in this embodiment, the backup battery 4 is used to temporarily supply power to the main board 1 of the terminal, so that the electric quantity of the backup battery 4 is smaller than that of the main battery 2.
In the embodiment of the present invention, the switch 3 is configured to determine to switch the output end 34 of the switch 3 to the first input end 32 or the second input end 33 according to an enable signal of the enable end 31, the main board 1 of the terminal is powered by a battery connected to the input end, and when the output end of the switch 3 is connected to a different input end, the main board 1 of the terminal is powered by a different battery.
The enable signal of the enable terminal 31 is determined by the state of the main battery 2, and the state of the main battery 2 includes a bit state and an off-bit state. The state of the main battery 2 is in place, that is, the main battery 2 is mounted in a battery mounting groove, and the state of the main battery 2 is not in place, that is, the main battery 2 is pulled out from the mounting groove.
Optionally, when the state pin 22 of the main battery 2 is normally connected to the enable terminal 31 of the switch 3, it is determined that the state of the main battery 2 is at the present position, and the enable terminal 31 generates an enable signal of 1. Accordingly, when the state pin 22 of the main battery 2 is disconnected from the enable terminal 31 of the switch 3, it is determined that the state of the main battery 2 is not in place, and the enable terminal 31 generates an enable signal of 0.
In the embodiment of the present invention, when the terminal is in a normal power-on state and the main battery 2 is in place, the terminal detects an enable signal generated by the enable terminal 31, and when the enable signal of the enable terminal 31 is 1, the output terminal 34 of the switch 3 is switched to the first input terminal 32, so that the main battery 2 supplies power to the main board 1 of the terminal. When the main battery 2 is in place, the main battery 2 supplies power to the main board 1, and the backup battery 4 does not supply power. That is to say, in the solution of the present invention, the terminal determines whether the main battery 2 is in the on-position state or not through the detected enable signal, and supplies power to the main board 1 through the main battery 2 under the on-position state of the main battery 2, so as to save the electric quantity of the backup battery 4, and achieve the purpose of saving the electric quantity.
When the terminal device is in a power-on state, if the main battery 2 is suddenly pulled out, the state pin 22 of the main battery 2 is firstly disconnected from the enabling terminal 31, when the terminal detects that the enabling terminal 31 generates an enabling signal of 0, but the power supply pin 21 of the main battery 2 is still connected with the change-over switch 3 at the moment, the output end 34 of the change-over switch 3 is connected with the first input end, therefore, the output end of the change-over switch 3 has a signal output, the switch circuit 5 is in a conducting state, and the terminal switches the output end 34 of the change-over switch 3 to the second input end 33 in time, so that the terminal is switched to the standby battery 4 from the power supply of the main battery 2 to supply power to the main board 1 of the terminal instantly, that is, the seamless switching of the power supply of the terminal battery is realized, and the stable transmission of the terminal service is ensured.
When the output terminal 34 of the changeover switch 3 has a signal output, the switch circuit 5 is in a conducting state. When the output terminal 34 of the changeover switch 3 does not output a signal, the switch circuit 5 is in an off state. When the enable signal is 1, the output terminal 34 of the switch 3 outputs a signal, when the enable signal is 0, the output terminal 34 of the switch 3 outputs no signal, or when the terminal detects that the enable signal is high level, the output terminal 34 of the switch 3 outputs a signal, and when the enable signal is low level, the output terminal 34 of the switch 3 outputs no signal. The output signal of the output terminal 34 can be regarded as 0 when no signal is output from the output terminal 34 of the switch 3, and the output signal of the output terminal 34 can be regarded as 1 when the signal is output from the output terminal 34 of the switch 3.
When the terminal device is in a shutdown state and the main battery 2 is in place, the output end of the switch 3 does not output a signal, and the switch circuit 5 is in a cut-off state, so that the connection between the backup battery 4 and the output end of the switch 3 cannot be established, that is, the terminal cannot be started through the backup battery 4. Therefore, the terminal device is powered on in the power-off state, and can be powered on only through the main battery 2.
Specifically, when the terminal is in the power-off state, the output signal of the switch 3 is 0, and at this time, the switch circuit 5 is in the off state, and the output 34 of the switch 3 may be connected to the first input terminal 31 (when the main battery 2 is in place, the enable signal is 1), or may be connected to the second input terminal 32 (when the main battery 2 is not in place, the enable signal is 0). Here, even if the output terminal 34 of the switch 3 is connected to the second input terminal 32, since there is no signal output from the output terminal, the switch circuit 5 is in the off state, so that the standby battery 4 cannot be normally connected to the output terminal 34 of the switch, and the terminal cannot be started up by the standby battery 4 in the off state, thereby saving the electric quantity of the standby battery 4.
On the basis of the above embodiment, in the embodiment of the present invention, the enable signal may also be represented by a low level signal when the state of the main battery 2 is in place, and may also be represented by a high level signal when the state of the main battery is not in place.
Illustratively, the enable signal generated by the enable terminal 31 is high or low. Wherein, the enable signal generated by the enable terminal 31 is in a high level state, the high level indicates that the enable terminal 31 has a voltage signal input, the enable signal generated by the enable terminal 31 is in a low level state, and the low level indicates that the enable terminal 31 has no voltage signal input. The terminal determines whether the main battery 2 is in place according to the connection state of the state pin 22 of the main battery 2 mounted on the main board 1 and the enable terminal 31 of the switch 3, for example, when the state of the main battery 2 is in place, the enable signal generated by the enable terminal 31 is a high level signal. If the state of the main battery 2 is not in place, the enable signal generated by the enable terminal 31 is a low level signal. In the embodiment of the invention, in a normal starting state of the terminal, the terminal determines that the enabling signal is a high-level signal according to the state of the main battery 2 being in place, the main battery 2 supplies power to the mainboard 1, the terminal determines that the enabling signal is a low-level signal according to the state of the main battery 2 being out of place, and the backup battery 4 supplies power to the mainboard 1.
On the basis of the above embodiment, in this embodiment, the main battery further includes a temperature detection pin. In the embodiment of the present invention, the temperature detection pin is a pin on the main battery 2, when the main battery 2 is in normal operation, the temperature of the main battery 2 is obtained through the temperature detection pin, and when the temperature of the main battery 2 reaches a preset temperature, a metal element of the temperature detection pin is heated to generate an internal stress to be rapidly disconnected from an electric shock, so as to cut off the connection between the main battery 2 and the first input terminal 32, thereby protecting the main battery 2 from being damaged.
In order to realize seamless switching between the main battery 2 and the backup 4, the invention needs to ensure that when the main battery 2 is suddenly pulled down, the state pin 22 in the main battery 2 is firstly disconnected with the enabling terminal 31 in the switch 3, and then the power supply pin in the main battery 2 is disconnected. After the status pin 22 is disconnected, the enable terminal 31 generates a low level signal, and since the power supply pin is disconnected, when the enable terminal 31 generates a low level channel, the output terminal of the switch 3 outputs a signal, after the terminal detects the low level signal, the switch circuit 5 is in a cut-off state according to the signal of the control terminal, and the terminal switches the output terminal 34 of the switch 3 to the second input terminal 33, so that the terminal is switched from the power supply of the main battery 2 to the standby battery 4 to supply power to the main board 1 of the terminal instantaneously, that is, seamless switching of power supply of the terminal battery is realized, and further, the stability of the system is improved.
In this embodiment, when the main battery 2 is suddenly pulled down, the state pin 22 in the main battery 2 is first disconnected from the enable terminal 31 in the switch 3, and then the power pin in the main battery 2 is disconnected.
In the first mode, the first part is a first elastic sheet, the second part is a second elastic sheet, the first elastic sheet is located in the first groove, the second elastic sheet is located in the second groove, the first elastic sheet and the second elastic sheet are the same, and the depth of the first groove is larger than that of the second groove. Because the depth of the first groove is greater than that of the second groove, and the first elastic sheet and the second elastic sheet are the same, the position of the first elastic sheet is lower than that of the second elastic sheet on the whole, so when the main battery 2 is pulled down, the state pin of the main battery 2 connected with the second elastic sheet in the second groove is firstly disconnected with the change-over switch 3.
Referring to fig. 4, the grooves are grooves provided under at least three surface recesses at the position of connection with the main board in the main battery 2, wherein the number of the grooves is at least 3, and may include more. In the structure shown in fig. 4, there are 4 grooves: the temperature detection device comprises a first groove, two second grooves and a temperature pin groove, wherein the first groove is a groove for accommodating a state pin, the second groove is a groove for accommodating a power supply pin, the power supply pin comprises a positive electrode pin and a negative electrode pin of a battery, and therefore the two second grooves are total and the temperature pin groove is used for accommodating a temperature detection pin. The temperature pin recess is an optional recess, and in some embodiments of the present invention, the temperature pin recess may not be included. It will be appreciated that more pins may be included in possible implementations of the invention than the four recesses described above.
The elastic sheet is arranged on the main board 1, and as shown in fig. 5, the elastic sheet can be a metal elastic sheet, and the elastic sheet is an important component on the switch and the connecting component.
Illustratively, the depth of the first groove is 10mm, and the depth of the second groove is 8mm, so that at the moment when the main battery 2 is suddenly pulled down, the status pin 22 in the main battery 2 is disconnected with the enable terminal 31 in the switch 3 first, and the enable terminal 31 generates a low level signal, but the output terminal of the switch 3 is not disconnected with the switch 3 temporarily due to power referral, so that there is a signal output, after the terminal detects the low level signal, the switch circuit 5 closes the circuit according to the signal of the control terminal, and the terminal switches the output terminal 34 of the switch 3 to the second input terminal 33, so that the terminal is switched from the moment when the main battery 2 supplies power to the backup battery 4 to supply power to the main board 1 of the terminal, that is, seamless switching of the terminal battery power supply is realized. In the embodiment of the present invention, the depth of the groove is only illustrated, and the depths of the first groove and the second groove are not limited to this depth, and may be other values, and may be set reasonably according to the requirements of the actual situation.
In the second mode, the first part is a first elastic sheet, the second part is a second elastic sheet, the first elastic sheet is located in the first groove, the second elastic sheet is located in the second groove, the depth of the first groove is the same as that of the second groove, and the height of the first elastic sheet is smaller than that of the second elastic sheet. Because the depth of the first groove is equal to the depth of the second groove, and the height of the first elastic sheet is higher than that of the second elastic sheet and is smaller than that of the second elastic sheet, the position of the first elastic sheet is lower than that of the second elastic sheet on the whole, and therefore when the main battery 2 is pulled down, the state pin of the main battery 2 connected with the second elastic sheet in the second groove is disconnected with the switch 3 firstly.
In the embodiment of the present invention, the switch circuit may be a MOS transistor, but is not limited to a MOS transistor, and may also be other circuits capable of passing or blocking an analog signal, such as a transistor or a diode. A first terminal of the switch circuit 5 is connected to the backup battery 4, a second terminal of the switch circuit 5 is connected to the output terminal 34 of the change-over switch 3, and a third terminal of the switch circuit 5 is connected to the second input terminal 33 of the change-over switch 3.
Taking the switching circuit as an MOS transistor as an example, when the terminal is in a power-on state, the main battery 2 is in place, that is, the main battery 2 is connected to the first input terminal 32 to supply power to the terminal, at this time, the output terminal 34 has a signal output, the signal can be detected at the connection between the MOS transistor and the output terminal 34, and the MOS transistor in the switching circuit 5 can block the circuit, so that the standby battery 4 is disconnected from the second input terminal 34. In the embodiment, in the shutdown state of the terminal, the main battery 2 is in place, but the output end 34 of the switch 3 has no signal output, at this time, a signal is not detected at a connection position of the MOS transistor and the output end 34, and the MOS transistor in the switch circuit 5 can be connected with a circuit, so that the backup battery 4 is connected with the second input end 34, and whether the terminal is powered by the backup battery 4 depends on whether the output end 34 of the switch 3 is connected with the second input end 33.
