Description

Electronic device comprising a battery reset structure

[0001] Embodiments disclosed in this document relate to an electronic device including a battery reset structure.

[0002] Electronic devices such as smart phones, tablet PCs, portable multimedia players (PMPs), personal digital assistants (PDAs), laptop personal computers, and wearable devices such as wrist watches and head-mounted displays (HMDs) may include batteries to ensure portability.

[0003] Meanwhile, for electronic devices, replaceable, detachable batteries may be used, taking into account the unit price of the product.

[0004] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0005] Depending on the type of electronic device, a replaceable, removable battery may be used instead of a rechargeable, reusable, integrated battery. For example, in low-power electronic devices, a removable battery may be used to reduce unit cost.

[0006] Meanwhile, in the case of electronic devices with low power consumption, even if the battery is removed, it may take some time for the residual power remaining in the internal circuitry to be consumed. In such cases, even if the battery is removed, the residual power may cause malfunctions in the electronic device. For example, even if the battery is removed, the electronic device may detect the battery as still installed due to the residual power, resulting in abnormal operation and communication with external electronic devices.

[0007] Additionally, when a new battery is installed before the battery is removed and its remaining power is fully depleted, it may take some time for the device to recognize that the new battery has been replaced. In such cases, the electronic device may not detect the new battery for a certain period of time, and the device may perceive its power status as low.

[0008] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0009] According to one embodiment of the present disclosure, an electronic device may include a printed circuit board including an opening. In addition, the electronic device may include a switch circuit disposed on the printed circuit board, the switch circuit including an input portion to which a power signal of a battery is applied, an output portion to which the power signal is output, and a first ground. In addition, the electronic device may include a control circuit disposed on the printed circuit board, the control circuit controlling a connection between the input portion and the output portion, and including a contact terminal. In addition, the electronic device may include the positive terminal connected to the printed circuit board to transmit the battery power signal. In addition, the electronic device may include a body portion facing the contact terminal of the control circuit portion and having a control pin formed thereon, and a negative contact portion at least a portion of which is positioned in the opening and contacts a negative electrode of the battery, and a negative terminal connected to a second ground (G2) of the printed circuit board.

[0013] According to one embodiment of the present disclosure, a structure can be proposed that immediately consumes the remaining power of an electronic device when the battery is disconnected.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0050] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.
