Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] Folding phones usually use a dual-battery (first battery and second battery) power supply system to power the internal power management chip because they need to change between unfolded and folded forms. During normal operation, the two batteries are connected in parallel to supply power together, with the second battery having a larger capacity and power supply capacity than the first battery. In order to ensure that the voltages of the two batteries remain balanced during the power supply process and to prevent the two from damaging the mobile phone circuit or causing performance degradation due to excessive voltage differences, a balancing resistor is set between the two batteries. The balancing resistor can adjust the charge and discharge status between the two batteries to keep the voltages of the two batteries balanced.

[0003] However, before the foldable phone is started, if only the first battery with a smaller capacity is fastened, the first battery will discharge at a higher rate in the initial stage, generating a relatively high instantaneous voltage. At this time, part of the current will flow into the power management chip through the balancing resistor, temporarily triggering the phone startup process. However, as the first battery continues to discharge, its output current and voltage drop rapidly. When the current intensity is not enough to maintain the stable power supply required for normal operation, the phone will start briefly but may not be able to complete the initialization process smoothly, resulting in startup failure.

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0037] Example 1

[0038] like Figures 1 to 5 As shown, Embodiment 1 of the present application provides an electronic device, including:

[0039] First battery 1;

[0040] A first connector 2, capable of being electrically connected to the first battery 1 and the power management chip 6 respectively;

[0041] A second battery 3, wherein the capacity of the second battery 3 is smaller than the capacity of the first battery 1;

[0042] The second connector 4 can be electrically connected to the second battery 3 and the power management chip 6 respectively;

[0043] The resistor 5 is electrically connected to the first connector 2 and the second connector 4 respectively. The resistor 5 can be in an open circuit state when the first battery 1 and the first connector 2 are not electrically connected.

[0044] The electronic device of the present application can be applied to electronic devices such as foldable mobile phones and foldable tablet computers.

[0045] Specifically, the first battery 1 is used as the main power source, and its capacity is greater than that of the second battery 3, and can provide a long-lasting and stable power supply for the electronic device. When the electronic device is started, the first battery 1 and the second battery 3 can be electrically connected to the power management chip 6 through their respective connectors at the same time, and jointly supply power to the power management chip 6; or, the first battery 1 can supply power to the power management chip 6 through the first connector 2 alone, that is, when the second battery 3 and the second connector 4 are not electrically connected and are in an open circuit state, the first battery 1 can provide power to the power management chip 6 through the first connector 2.

[0046] The second battery 3 is used as an auxiliary power source to optimize the power supply performance. The second battery 3 can be electrically connected to the power management chip 6 through the second connector 4 .

[0047] The resistor 5 can maintain a voltage balance between the first battery 1 and the second battery 3 when they are powered together, and can also be in an open circuit state when the first battery 1 and the first connector 2 are not electrically connected. For example, when using a foldable mobile phone, the second battery 3 is first fastened, and the resistor 5 can be in an open circuit state, thereby effectively preventing the formation of an unexpected current path and avoiding the problem of electronic equipment failing to start up due to unexpected power supply of the second battery 3.

[0048] In the electronic device provided in Example 1 of the present application, when the second battery 3 with a smaller capacity is connected, the resistor 5 is in an open circuit state, cutting off the path for the second battery 3 to supply power to the power management chip 6, effectively avoiding the voltage drop or instability caused by the instantaneous large current discharge of the second battery 3, thereby reducing the risk of startup failure caused by unstable battery voltage, and providing a safe and stable startup environment for the electronic device. At the same time, when the two batteries work in parallel, it is also possible to maintain a relatively balanced voltage level between the two batteries by dynamically adjusting the charge and discharge rate between the two batteries, that is, during the period of dual battery power supply, ensure that the power management chip 6 receives a stable and adaptive voltage input, thereby avoiding the adverse effect of excessive voltage differences between the batteries on the power management chip 6.

[0049] like Figure 1 As shown, in some embodiments, the first battery 1 includes a first pin 11;

[0050] The first connector 2 includes a first pin 21 and a second pin 22 spaced apart from each other; the first pin 11 is used to electrically connect to the first pin 21 and the second pin 22 at the same time, the first pin 21 is used to electrically connect to the power management chip 6, and the second pin 22 is electrically connected to one end of the resistor 5.

[0051] Specifically, the first battery 1 also includes a first body 12, and the number of first pins 11 can be two. The two first pins 11 are arranged at intervals in the first body 12 and are electrically connected to the first body 12 to ensure that the electric energy stored in the first body 12 can be transmitted outward through the two first pins 11. The spacing between the two first pins 11 matches the spacing between the first pin 21 and the second pin 22. When the first battery 1 and the first connector 2 are assembled, the first pin 21 and the second pin 22 can be electrically connected to one first pin 11 at the same time, so that the electric energy of the first battery 1 can flow to the power management chip 6 and the resistor 5 respectively through the two first pins 11, forming two independent current conduction paths. Since one end of the resistor 5 is electrically connected to the second pin 22 and the other end of the resistor 5 is connected to the second connector 4, the voltage of the two batteries working together is balanced; and when only the second battery 3 is connected, the resistor 5 will automatically be in an open circuit state, thereby avoiding the voltage instability or current misflow problem that may be caused by the second battery 3 being powered alone, and ensuring that the electronic device can operate in a safe and stable power supply environment when it is started.

[0052] like Figure 1 As shown, in some embodiments, the second battery 3 includes a second pin 31;

[0053] The second connector 4 includes a third pin 41 ; the second pin 31 can be electrically connected to the third pin 41 , and the third pin 41 is used to be electrically connected to the power management chip 6 .

[0054] Specifically, the second battery 3 further includes a second body 32, and the second pin 31 is electrically connected to the second body 32 to ensure that the electric energy stored in the second body 32 can be transmitted to the outside through the second pin 31. The number of the second pin 31 can be one or two. When the number of the second pin 31 is one, such as Figure 1 As shown, the other end of the resistor 5 is electrically connected to the third pin 41 , the electric energy of the second battery 3 is transmitted to the power management chip 6 through the second pin 31 and the third pin 41 , and the voltage is regulated through the resistor 5 .

[0055] When the number of the second pins 31 is two, as Figure 2 As shown, in some embodiments, the second connector 4 further includes a fourth pin 42 , the fourth pin 42 is spaced apart from the third pin 41 , and the other end of the resistor 5 is electrically connected to the fourth pin 42 .

[0056] Specifically, the two second pins 31 are spaced apart from each other in the second body 32 and can both be electrically connected to the second body 32. The spacing between the two second pins 31 matches the spacing between the third pin 41 and the fourth pin 42. When the second battery 3 and the second connector 4 are assembled, the third pin 41 and the fourth pin 42 can each be electrically connected to one second pin 31 at the same time, so that the electric energy of the second battery 3 can flow to the power management chip 6 and the resistor 5 respectively through the two second pins 31, forming two independent current conduction paths.

[0057] like Figures 3 to 5 As shown, in some embodiments, it also includes:

[0058] The first induction switch 7 is electrically connected to the resistor 5; the first induction switch 7 is signal-connected to the first connector 2, and the first induction switch 7 is used to receive a shutdown signal sent by the first connector 2 when the first connector 2 and the first battery 1 are not electrically connected.

[0059] Specifically, when the first battery 1 is not electrically connected to the first connector 2, the first connector 2 detects that the first battery 1 is disconnected, generates a shutdown signal and sends the shutdown signal to the first induction switch 7. After receiving the shutdown signal, the first induction switch 7 cuts off the current in the branch where the resistor 5 is located, ensuring that when the first battery 1 is not electrically connected, the second battery 3 will not supply power to the power management chip 6, thereby enhancing the safety and stability of the electronic device during the startup process.

[0060] The first induction switch 7 can be a Hall effect switch or a solid-state relay.

[0061] One end of the resistor 5 can be electrically connected to the wire connecting the first connector 2 and the power management chip 6, and the other end of the resistor 5 can be electrically connected to the wire connecting the second connector 4 and the power management chip 6. Figure 3As shown, in some embodiments, the first inductive switch 7 is electrically connected to the first connector 2. In this case, the first inductive switch 7 can be arranged between the first connector 2 and the other end of the resistor 5. When the first inductive switch 7 receives a shutdown signal, the current flow can be effectively blocked to prevent the second battery 3 from mistakenly supplying power to the power management chip 6 when the first battery 1 is not connected, thereby improving the safety and stability of the electronic device during the startup phase; or Figure 4 and Figure 5 As shown, in some embodiments, the first induction switch 7 is used to be electrically connected to the power management chip 6. In this case, the first induction switch 7 can be set between one end of the resistor 5 and the power management chip 6 to prevent the second battery 3 from powering the power management chip 6 alone.

[0062] like Figures 1 to 5 As shown, in some embodiments, a second induction switch 8 is also included;

[0063] The second induction switch 8 is electrically connected to the first connector 2 and the power management chip 6 respectively; the second induction switch 8 is signal-connected to the first connector 2, and the second induction switch 8 is used to receive a shutdown signal sent by the first connector 2 when the first connector 2 and the first battery 1 are not electrically connected.

[0064] Specifically, the second induction switch 8 can be connected in parallel with the resistor 5 to cut off the current flowing to the power management chip 6, ensuring that when the first battery 1 is not connected or disconnected, the second battery 3 will not mistakenly supply power to the power management chip 6, thereby greatly improving the safety and stability of the electronic device startup phase and even the entire working cycle.

[0065] The second induction switch 8 can be a Hall effect switch or a solid-state relay.

[0066] Example 2

[0067] like Figures 1 to 5 As shown, Embodiment 2 of the present application provides an electronic device, including:

[0068] A first body (not shown);

[0069] The second body (not shown in the figure) is rotatably connected to the first body, and the rotation of the second body can make the two bodies form a folded state or an unfolded state;

[0070] A power management chip 6, arranged in the first body or the second body;

[0071] Dual battery powered system, including:

[0072] A first battery 1, disposed in the first body;

[0073] A first connector 2 is electrically connected to the first battery 1 and the power management chip 6 respectively;

[0074] A second battery 3, disposed in the second body, the capacity of the second battery 3 being smaller than the capacity of the first battery 1;

[0075] The second connector 4 is electrically connected to the second battery 3 and the power management chip 6 respectively;

[0076] The resistor 5 is electrically connected to the first connector 2 and the second connector 4 respectively. The resistor 5 can be in an open circuit state when the first battery 1 and the first connector 2 are not electrically connected.

[0077] The electronic device may be a foldable electronic device such as a foldable mobile phone or a foldable tablet computer.

[0078] The first body and the second body can be rotatably connected by a hinge or a shaft, so that the electronic device can be switched between the folded and unfolded states. The specific structure and connection method of the first body and the second body are known to those skilled in the art and will not be described in detail here.

[0079] In order to ensure the stability of the connection between the first battery 1 and the second battery 3, the first battery 1 can be fixedly arranged on the first body, and the second battery 3 can be fixedly arranged on the second body.

[0080] In the electronic device provided in Example 2 of the present application, when the second battery 3 with a smaller capacity is connected, the resistor 5 is in an open circuit state, cutting off the path for the second battery 3 to supply power to the power management chip 6, effectively avoiding the voltage drop or instability caused by the instantaneous large current discharge of the second battery 3, thereby reducing the risk of startup failure caused by unstable battery voltage, and providing a safe and stable startup environment for the electronic device. At the same time, when the two batteries work in parallel, it is also possible to help maintain a relatively balanced voltage level between the two batteries by dynamically adjusting the charge and discharge rate between the two batteries, that is, during the period of dual battery power supply, ensure that the power management chip 6 receives a stable and adaptive voltage input, thereby avoiding the adverse effect of the power management chip 6 due to excessive voltage differences between the batteries, thereby improving the startup safety and operation stability of the entire electronic device.
