All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
The term "comprising" in the description of the application and the claims and in the above figures and any variants thereof is intended to cover a non-exclusive inclusion. For example, a process, method, or system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed but may optionally include additional steps or elements not listed or inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," and "third," etc. are used for distinguishing between different objects and not for describing a particular sequential order.
First, the terms involved in the present application will be explained:
enabling end: also called enable input, is a control signal input that is an input port of a circuit or an input pin of a chip, only which pin is activated, the circuit or chip can operate.
MOS tube: refers to a metal oxide semiconductor field effect transistor (Metal Oxide Semiconductor, MOS) used in a reverse protection circuit.
Temperature detection pin: the bimetallic strip is used as a temperature sensing element, the temperature change of the battery is displayed in a voltage change form, and the temperature of the battery is reported in real time.
The rapid development of the mobile intelligent terminal age, the standby time of the terminal is focused by the majority of users, and in order to increase the standby time of the terminal, a standby battery is added in the terminal, and when the electric quantity of the 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 main battery and a standby battery are contained in a terminal, the power supply of the terminal can be controlled by software to switch between the main battery and the standby battery. For example, in the using process of the terminal, the electricity consumption condition of the main battery is monitored in real time, and when the voltage of the main battery is lower than a preset voltage threshold value, the power supply of the terminal is switched from the main battery to the standby battery.
However, the prior art method of switching batteries by software has limited the use of some scenarios. For example, in the case that the voltage of the main battery of the terminal is not lower than the preset threshold value, if the main battery of the terminal is suddenly removed by external action, the terminal cannot be switched to the standby battery to supply power in time, so that the service being transmitted is interrupted.
The application provides a terminal with a battery switching function, which aims to solve the technical problems in the prior art.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a terminal with a battery switching function according to an embodiment of the present application, fig. 2 is a schematic diagram of a switch according to an embodiment of the present application, fig. 3 is a schematic diagram of a pin structure of a main battery according to an embodiment of the present application, fig. 4 is a schematic diagram of a battery groove according to an embodiment of the present application, and fig. 5 is a schematic diagram of a motherboard spring sheet according to an embodiment of the present application. The terminal can be a mobile phone, a tablet personal computer, an MP4 playing terminal, a learning machine, a point-reading machine, an electronic dictionary or a vehicle-mounted terminal, etc.
Referring to fig. 1, the terminal includes a main board 1, and a main battery 2, a standby 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 application, the main battery 2 and the standby battery 4 are all power energy storage tools of the terminal, wherein the main battery 2 and the standby battery 4 can be lithium batteries or nickel-metal hydride batteries, and can also be other types of batteries. The main battery 2 and the backup battery 4 are 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 switches between the first input terminal 32 and the second input terminal 33. The main battery 2 comprises a power supply pin 21 and a state pin 22, wherein the state pin 22 of the main battery 2 is connected with the enabling end 31 of the switch 3, the power supply pin 21 is connected with the main board 1, the height of a first component connected with the power supply pin 21 of the main board 1 is smaller than the height of a second component of the state pin 22, the state pin 22 is connected with the enabling end 31 of the switch 3, and the power supply pin 21 of the main battery 2 is connected with the first input end 32 of the switch 3 through the first component.
The state 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, the enable signal of the enable terminal 31 is related to the signal of the state pin 22, for example, when the main battery 2 is in place, the state 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 can be represented by 1. When the main battery 2 is out of position (e.g. after being detached), the state pin 22 of the main battery 2 is disconnected from the enable terminal 31 of the switching circuit 31, in which state the enable signal of the enable terminal 31 may be denoted by 0.
The standby battery 4 is connected with the second input end 32 of the change-over switch 3 through the switch circuit 5, the output end 34 of the change-over switch 3 is connected with the control end 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 the signal of the control end.
The standby battery 4 is generally used for maintaining information such as system configuration, date and time in a special memory area of the terminal, so that the standby battery 4 is used for temporarily supplying power to the main board 1 of the terminal in this embodiment, and therefore the power of the standby battery 4 is smaller than that of the main battery 2.
In the embodiment of the present application, the switch 3 is configured to determine, according to the enable signal of the enable terminal 31, to switch the output terminal 34 of the switch 3 to the first input terminal 32 or the second input terminal 33, where the main board 1 of the terminal is powered by a battery connected to the input terminal, and when the output terminal of the switch 3 is connected to a different input terminal, 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 an in-place and an out-of-place state. The state of the main battery 2 in place means that the main battery 2 is mounted in a mounting groove of the battery, and the state of the main battery 2 out of place means that the main battery 2 is pulled out of the mounting groove.
Alternatively, when the state pin 22 of the main battery 2 is normally connected to the enable terminal 31 of the switch 3, the state of the main battery 2 is determined to be in place, and the enable terminal 31 generates the 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, the state of the main battery 2 is determined to be out of place, and the enable terminal 31 generates an enable signal of 0.
In the embodiment of the present application, when the terminal is in a normal power-on state and the main battery 2 is in place, the terminal detects the 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. With the main battery 2 in place, the main board 1 is powered only by the main battery 2, and the backup battery 4 is not powered. That is, in the scheme of the application, the terminal judges whether the main battery 2 is in the right state or not through the detected enabling signal, and the main battery 2 supplies power to the main board 1 under the condition that the main battery 2 is in place, so that the electric quantity of the standby battery 4 is saved, and the purpose of saving the electric quantity is achieved.
When the terminal device is in a starting state, if the main battery 2 is suddenly pulled out, the state pin 22 of the main battery 2 is disconnected with the enabling end 31 first, and the terminal detects that the enabling end 31 generates an enabling signal of 0, but at the moment, the power pin 21 of the main battery 2 is still connected with the switch 3, the output end 34 of the switch 3 is connected with the first input end, so that the output end of the switch 3 has signal output, the switch circuit 5 is in a conducting state, and the terminal timely switches the output end 34 of the switch 3 to the second input end 33, so that the terminal is instantly switched from the power supply of the main battery 2 to the power supply of the standby battery 4 to supply power to the main board 1 of the terminal, namely, seamless switching of power supply of the terminal battery is realized, and stable transmission of terminal service is ensured.
When the output terminal 34 of the change-over switch 3 has a signal output, the switch circuit 5 is in a conductive state. When the output terminal 34 of the changeover switch 3 has no signal output, the switching circuit 5 is in an off state. When the enable signal is 1, the output terminal 34 of the switch 3 has a signal output, when the enable signal is 0, the output terminal 34 of the switch 3 has no signal output, or when the terminal detects that the enable signal is high level, the output terminal 34 of the switch 3 has a signal output, and when the enable signal is low level, the output terminal 34 of the switch 3 has no signal output. The absence of a signal output from the output terminal 34 of the switch 3 may be regarded as 0 for the output signal from the output terminal 34, and the presence of a signal output from the output terminal 34 of the switch 3 may be regarded as 1 for the output signal from the output terminal 34.
When the terminal device is in a shutdown state and the main battery 2 is in place, the output end of the switch 3 has no output signal, and the switch circuit 5 is in a cut-off state, so that the connection between the standby battery 4 and the output end of the switch 3 cannot be established, i.e. the terminal cannot start up through the standby battery 4. Therefore, to start the power-on in the power-off state, the terminal device can start the power-on only through the main battery 2.
Specifically, when the terminal is in the 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 31 (when the main battery 2 is in place, the enable signal is 1), or may be connected to the second input 32 (when the main battery 2 is out of place, and 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 the output terminal has no signal output, the switch circuit 5 is in a turned-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 through the standby battery 4 in a turned-off state, thereby saving the electric quantity of the standby battery 4.
On the basis of the above-described embodiment, in the embodiment of the present application, the enable signal may be represented by a low-level signal when the state of the main battery 2 is in place, and the enable signal may be represented by a high-level signal when the state of the main battery is out of place.
The enable signal generated by the enable terminal 31 is illustratively either high or low. 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, and the enable signal generated by the enable terminal 31 is in a low level state, 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 application, 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, the main battery 2 supplies power to the main board 1, and the terminal determines that the enabling signal is a low-level signal according to the state of the main battery 2, and the standby battery 4 supplies power to the main board 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 application, the temperature detection pin is a pin on the main battery 2, when the main battery 2 works normally, the temperature of the main battery 2 is obtained through the temperature detection pin, and when the temperature of the main battery 2 reaches the preset temperature, the metal element of the temperature detection pin is heated to generate internal stress to be rapidly disconnected with an electric shock, and the connection between the main battery 2 and the first input end 32 is cut off, so that the main battery 2 is protected from damage.
In order to realize seamless switching between the main battery 2 and the standby 4 in the application, it is necessary to ensure that when the main battery 2 is suddenly pulled out, the state pin 22 in the main battery 2 is disconnected from the enabling terminal 31 in the switch 3, and then the power pin in the main battery 2 is disconnected. After the state pin 22 is disconnected, the enabling end 31 generates a low-level signal, and because the power supply pin is disconnected, when the enabling end 31 generates a low-level channel, the output end of the change-over switch 3 has a signal output, 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 end, and the terminal switches the output end 34 of the change-over switch 3 to the second input end 33, so that the terminal is instantly switched from the power supply of the main battery 2 to the power supply of the standby battery 4 to supply power for the main board 1 of the terminal, namely, the seamless switching of the power supply of the battery of the terminal is realized, and the stability of the system is further improved.
In this embodiment, when the main battery 2 is suddenly pulled out, the state pin 22 in the main battery 2 is disconnected from the enable terminal 31 in the switch 3, and then the power pin in the main battery 2 is disconnected.
In a first mode, the first component is a first elastic piece, the second component is a second elastic piece, the first elastic piece is located in the first groove, the second elastic piece is located in the second groove, the first elastic piece is identical to the second elastic piece, 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, the first elastic piece and the second elastic piece are the same, so that the position of the first elastic piece is lower than that of the second elastic piece as a whole, and when the main battery 2 is pulled down, the state pin of the main battery 2 connected with the second elastic piece in the second groove is disconnected with the change-over switch 3.
As shown in fig. 4, the grooves are grooves with at least three concave surfaces provided in the main battery 2 at the connection position with the main board, wherein the number of grooves is at least 3, and may include more. In the structure shown in fig. 4, there are 4 grooves: the battery temperature detection pin 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 pin, the power pin comprises a positive electrode pin and a negative electrode pin of a battery, and therefore, the two second grooves are shared, and the temperature pin groove is used for accommodating a temperature detection pin. Wherein the temperature pin groove is an optional groove, in some embodiments of the present application, the temperature pin groove may not be included. It will be appreciated that in addition to the four recesses described above, further pins may be included in a possible implementation of the application.
The spring is disposed on the motherboard 1, as shown in fig. 5, the spring may be a metal spring, and the spring is an important component of the switch and the connection component.
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 out, the state pin 22 in the main battery 2 is disconnected from the enabling end 31 in the switch 3, the enabling end 31 generates a low-level signal, but the output end of the switch 3 is not disconnected from the switch 3 temporarily due to the introduction of the power supply, so that a signal is output, after the terminal detects the low-level signal, the switch circuit 5 turns off the circuit according to the signal of the control end, and the terminal switches the output end 34 of the switch 3 onto the second input end 33, so that the terminal is switched from the instant of supplying power to the main battery 2 to the instant of supplying power to the standby battery 4 for supplying power to the main board 1 of the terminal, and the seamless switching of supplying power to the terminal battery is realized. In the embodiment of the present application, the depths of the grooves are only illustrated, the depths of the first groove and the second groove are not limited to the depths, and may be other values, and may be set reasonably according to the actual requirements.
In a second mode, the first component is a first elastic piece, the second component is a second elastic piece, the first elastic piece is located in the first groove, the second elastic piece is located in the second groove, the depth of the first groove is identical to that of the second groove, and the height of the first elastic piece is smaller than that of the second elastic piece. Since the depth of the first groove is equal to the depth of the second groove, the height Yu Xiaoyu of the first elastic piece and the height of the second elastic piece are equal, so that the position of the first elastic piece is lower than that of the second elastic piece as a whole, and when the main battery 2 is pulled down, the state pin of the main battery 2 connected with the second elastic piece in the second groove is disconnected with the switch 3.
In the embodiment of the present application, the switching circuit may be a MOS transistor, but is not limited to a MOS transistor, and may be other circuits that can pass or block an analog signal, for example, a transistor diode or a transistor. The first terminal of the switching circuit 5 is connected to the battery backup 4, the second terminal of the switching circuit 5 is connected to the output terminal 34 of the switch 3, and the third terminal of the switching circuit 5 is connected to the second input terminal 33 of the switch 3.
Taking a switch circuit as an example of a MOS tube, when the terminal is in a starting state, the main battery 2 is in place, namely the main battery 2 is connected with the first input end 32 to supply power to the terminal, at the moment, the output end 34 has signal output, the connection part of the MOS tube and the output end 34 can detect the signal, and the MOS tube in the switch circuit 5 can block the circuit, so that the standby battery 4 is disconnected with the second input end 34. In the embodiment, in the terminal shutdown state, the main battery 2 is in place, even if the enabling end 31 can generate an enabling signal, the connection between the MOS transistor and the output end 34 does not detect a signal, and at this time, the MOS transistor in the switch circuit 5 can be connected to the circuit, so that the standby battery 4 and the second input end 34 can be connected to each other, and whether the standby battery 4 supplies power to the terminal or not depends on whether the output end 34 of the switch 3 is connected to the second input end 33, in the terminal shutdown state, the main battery 2 is in place, even if the enabling end 31 can generate an enabling signal, the output end 34 is connected to the first input end 32, and not the output end 34 is connected to the second input end 33, therefore, the terminal cannot be powered to start up by the standby battery 4 in the shutdown state, and power consumption of the standby battery 4 is saved.
