Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, specifically to a portable electronic device. Background Technology

[0002] With the advancement of electronic technology, portable electronic devices, such as mobile phones, walkie-talkies, tablets, and laptops, are becoming increasingly integrated into people's lives. These portable electronic devices all contain at least one battery to ensure their functionality. Previously, the batteries in electronic devices were removable, meaning the device itself was separate from the battery, requiring users to charge or replace the battery when it was low. However, with the development of integrated, ultra-thin designs for electronic devices, the batteries in current electronic devices are all non-removable.

[0003] The non-removable battery design, while solving the problem of ultra-thin, integrated device design, brings many inconveniences to users. For example, to solve the problem of battery life, users have to buy larger power banks, which not only increase the weight of the device and incur extra costs, but are also inconvenient to use, seriously affecting the portability of the device. More seriously, the battery life is much shorter than the life of the electronic device. Generally, after two years, battery efficiency decreases, and replacing the battery in a phone with a non-removable battery is very troublesome. Most users have no choice but to replace the device, which undoubtedly shortens the lifespan of the device and increases the frequency of electronic device replacement.

[0004] Therefore, the reuse of removable battery structures is essential for some electronic devices. However, in previous products, replacing the battery required exiting the application and shutting down the device before turning it on again and running the application. In situations with low battery, this inevitably forces users to stop the current application, resulting in a poor user experience. Utility Model Content

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram of the structure of a portable electronic device provided in one embodiment of this application. Figure 1 As shown, the portable electronic device provided in this embodiment includes at least a battery compartment 110, a battery pack 120, a detection module 130, and a switching circuit 140.

[0041] In this embodiment, the battery compartment 110 of the portable electronic device includes at least a compartment body 1101 and a back cover 1102 for accommodating the battery pack 120. The compartment body 1101 and the back cover 1102 are connected by a slide rail or a snap fastener to form a detachable structure, which facilitates the replacement of the battery pack 120.

[0042] The battery pack 120 includes at least one main battery 1201 and one secondary battery 1202. The main battery 1201 is mainly used to power the portable electronic device and ensure its normal operation to achieve the preset functions. The secondary battery 1202 is used to power the portable electronic device when the main battery 1201 is depleted and needs to be replaced. This ensures that the portable electronic device can maintain power and achieve the preset basic functions during the period when the main battery 1201 is being replaced. In other words, it assists in replacing the battery of the portable electronic device without losing power.

[0043] In some embodiments, the main battery 1201 is a flat lithium battery and the auxiliary battery 1202 is a button lithium battery, which facilitates the miniaturization and convenience of portable electronic devices and makes them easier for users to use.

[0044] The detection module 130 is used to detect the connection status of the battery compartment 1101 and the rear cover 1102, and outputs a first signal indicating that the battery compartment 1101 and the rear cover 1102 are in a connected state, and a second signal indicating that the battery compartment 1101 and the rear cover 1102 are in a disassembled state. In other words, the detection module 130 can detect when the main battery 1201 is low on power and needs to be replaced. It first needs to disassemble the battery compartment 1101 and the rear cover 1102 to remove the main battery 1201 for replacement. That is, by detecting whether the battery compartment 1101 and the rear cover 1102 are in a disassembled state, the current status of the main battery 1201 can be determined, preparing for subsequent replacement of the main battery 1201 without power loss.

[0045] In some embodiments, the detection module 130 includes a Hall effect sensor and a magnetic sensor, wherein the Hall effect sensor and the magnetic sensor are arranged opposite to each other. If the Hall effect sensor is located inside the rear cover 1102, the magnetic sensor is located on one side of the compartment 1101 at the position corresponding to the Hall effect sensor; if the Hall effect sensor is located on one side of the compartment 1101, the magnetic sensor is located inside the rear cover 1102 at the position corresponding to the Hall effect sensor. It is understood that the Hall effect sensor and the magnetic sensor are arranged opposite to each other, that is, they are respectively installed on one side of the compartment 1101 and the rear cover 1102 of the battery compartment 110. When the compartment 1101 and the rear cover 1102 of the battery compartment 110 are connected, the Hall effect sensor can detect the magnetic field generated by the magnetic sensor, thereby realizing the detection of the connection state between the compartment 1101 and the rear cover 1102.

[0046] Hall effect sensors and magnetic sensors are commonly used to detect the position, velocity, or presence of objects. They operate based on the Hall effect, which states that when an electric current passes through a conductor in a magnetic field, the magnetic field creates a potential difference (Hall voltage) across the conductor. This effect can be used to detect changes in the magnetic field, thereby detecting the state of the associated object or system.

[0047] The Hall effect sensor includes a omnipolar magnet detection IC. When the magnetic detector approaches the Hall effect sensor, it generates a magnetic field around the Hall effect sensor. This magnetic field remains constant as long as the magnetism and position of the magnetic detector remain unchanged. When the magnetic field acts on the Hall effect sensor, a Hall voltage is generated on both sides of it. The magnitude of this voltage is proportional to the strength of the magnetic field. When the Hall effect sensor and the magnetic detector are connected, the magnetic field acts on the Hall effect sensor, and the omnipolar magnet detection IC in the Hall effect sensor acquires the Hall voltage and converts it into an electrical signal. When the connection is broken, the magnetic field disappears, and the Hall effect sensor no longer generates an electrical signal or the generated electrical signal changes. By detecting this change in electrical signal, the connection status between the two components, the compartment body 1101 and the rear cover 1102, can be determined.

[0048] In this embodiment, the switching circuit 140 is electrically connected to the detection module 130, the main battery 1201, and the auxiliary battery 1202, respectively. The switching circuit 140 is used to output a first switching signal in response to a first signal and a second switching signal in response to a second signal. The first switching signal is used to switch the power supply mode of the portable electronic device from the main battery 1201 to the auxiliary battery 1202; the second switching signal is used to switch the power supply mode of the portable electronic device from the auxiliary battery 1202 to the main battery 1201. That is, when the detection module 130 detects that the compartment 1101 and the back cover 1102 are in a disassembled state, the switching circuit 140 controls the power supply mode of the portable electronic device to switch from the main battery 1201 to the auxiliary battery 1202; and when the compartment 1101 and the back cover 1102 are in a connected state, the switching circuit 140 controls the power supply mode of the portable electronic device to switch from the auxiliary battery 1202 to the main battery 1201.

[0049] In summary, the portable electronic device provided in this embodiment includes a battery compartment, a battery pack, a detection module, and a switching circuit. The battery compartment includes a detachably connected body and a back cover, and the battery pack includes a main battery and a secondary battery. The detection module detects the connection status of the body and the back cover and outputs a first signal and a second signal indicating whether they are connected or disconnected. The switching circuit responds to the first signal by outputting a first switching signal to switch the power supply mode of the electronic device from main battery power to secondary battery power, and responds to the second signal by outputting a second switching signal to switch the power supply mode of the electronic device from secondary battery power to main battery power. This application, through the built-in detection module to detect the status of the battery compartment and the switching circuit, achieves the requirement of uninterrupted power supply when removing the battery compartment to replace the main battery, improving user experience and satisfaction.

[0050] Figure 2 This is a schematic diagram of the structure of a portable electronic device provided in another embodiment of this application. (See diagram below.) Figure 2 As shown, the portable electronic device provided in this embodiment, based on any of the above embodiments, further includes at least one of a control module 150 and a charging circuit 160.

[0051] In this embodiment, the control module 150 is connected between the detection module 130 and the switching circuit 140. The control module 150 is used to receive a first signal output by the detection module 130, which indicates that the charging compartment body 1101 and the back cover 1102 are in a connected state, and a second signal, which indicates that the charging compartment body 1101 and the back cover 1102 are in a disassembled state. Based on the first signal or the second signal, the control module 150 controls the switching circuit 140 to output a first switching signal and a second switching signal, thereby realizing the switching of the power supply mode of the portable electronic device.

[0052] In some embodiments, the switching circuit 140 is also used to output a charging signal after outputting the second switching signal, to control the main battery 1201 to charge the auxiliary battery 1202. That is, when the switching circuit 140 outputs the second switching signal, it indicates that the charging compartment body 1101 and the back cover 1102 are connected. This can be understood as the battery compartment 1100 being powered by the main battery 1201 after the main battery 1201 has been replaced and the back cover 1102 has been closed again. At this time, the electronic device is powered by the main battery 1201. Since the auxiliary battery 1202 has been supplying power to the electronic device during the previous replacement of the main battery 1201, the auxiliary battery 1202 has lost some power. The charging signal output by the switching circuit 140 is used to control the main battery 1201 to charge the auxiliary battery 1202 to replenish its power loss.

[0053] In some embodiments, the charging circuit 160 responds to the charging signal output by the switching circuit 140 to charge the main battery 1201 to the auxiliary battery 1202. The charging circuit 160 includes at least a boost circuit and a charging sub-circuit. The boost circuit is connected to the main battery 1201 and is used to increase the battery voltage to the charging voltage. The charging sub-circuit is connected between the boost circuit and the auxiliary battery 1202 to complete the charging process from the main battery 1201 to the auxiliary battery 1202.
