Description

Technical Field

[0001] This utility model specifically relates to a rechargeable battery and a charging case, belonging to the field of rechargeable battery technology. Background Technology

[0002] In the field of modern electronic devices, the need for 3V power supply is widespread across numerous niche scenarios. Taking imaging equipment as an example, the Fujifilm Instax mini series instant cameras rely on 3V lithium batteries to drive the imaging module for precise exposure and the flash for instantaneous high-intensity flash. Using 3.7V lithium batteries would not only damage the delicate imaging sensor and flash drive circuitry due to the excessive voltage, but also require an additional step-down module, leading to increased camera size and cost. In the field of smart home control, high-end smart TVs and audio remote controls, equipped with infrared / Bluetooth signal transmission, voice recognition, and other multi-functional modules, have stringent requirements for rechargeable battery stability. 3V lithium batteries can provide stable and compatible power, ensuring accurate control and long battery life in complex environments. Furthermore, devices such as portable medical diagnostic instruments and IoT micro-sensors also prioritize 3V lithium batteries as rechargeable batteries due to factors such as voltage matching requirements, cost and complexity control, and battery size and shape compatibility. This ensures stable operation of the device and fully leverages the advantages of 3V lithium batteries, such as good voltage adaptability and high energy density.

[0003] However, the current mainstream voltage standards in the lithium battery industry are highly concentrated on specifications such as 3.7V (or nominal 3.6V) and 4.2V (full charge voltage). While these standard voltage systems have demonstrated significant advantages in energy density, charge / discharge performance, and device compatibility through long-term practical verification in large consumer electronics and power fields such as smartphones, laptops, and electric vehicles, they are difficult to directly apply in the specific scenarios requiring 3V power supply. Under current technology, forcibly using 3.7V lithium batteries for power supply not only requires the design of complex step-down and voltage regulation circuits, increasing equipment costs and failure rates, but may also reduce overall energy efficiency due to voltage conversion losses. Furthermore, the 3V lithium battery products on the market are mainly disposable batteries such as lithium manganese batteries. These batteries not only require frequent replacement, significantly increasing user costs, but also cause environmental problems such as heavy metal pollution due to the indiscriminate disposal of waste batteries, which is inconsistent with the concept of green and sustainable development. In addition, the existing limited number of 3V rechargeable lithium batteries have technical defects such as short cycle life, low charge / discharge efficiency, and poor high-temperature performance, making it difficult to meet the requirements for long-term stable operation of equipment.

[0004] Against this backdrop, the development of a rechargeable battery that maintains a voltage of around 3V, possesses high cycle stability, high energy density, and fast charge / discharge performance is urgently needed. This battery would not only fill a market gap and meet the dual requirements of stable 3V power supply and rechargeability for specific electronic devices, but also effectively reduce user costs, decrease environmental pollution, and drive technological innovation and sustainable development in fields such as imaging equipment, smart homes, medical electronics, and the Internet of Things. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a rechargeable battery, comprising:

[0006] An external housing includes a housing housing and an opening provided on the housing housing.

[0007] The rechargeable battery is detachably housed within the external housing.

[0008] A charging interface is exposed at the opening when the rechargeable battery is inside the external housing.

[0009] The conversion circuit module is connected at both ends to the rechargeable battery and the charging interface, respectively. After passing through the conversion circuit module, the output voltage of the rechargeable battery is 3±0.1V.

[0010] Preferably, the rechargeable battery is a lithium battery.

[0011] A charging case, comprising:

[0012] The first and second boxes are connected by the activity;

[0013] The first box contains a charging base, and the charging base contains at least one charging compartment;

[0014] The second box is equipped with a conductive device, which corresponds one-to-one with the charging compartment;

[0015] When the second housing is closed on the first housing, the conductive device is electrically connected to the rechargeable battery inside the first housing.

[0016] Preferably, it also includes a fixing device disposed in the first box and the second box.

[0017] The beneficial effects of this utility model are:

[0018] 1. This rechargeable battery uses a conversion circuit module to reduce the voltage to approximately 3V for charging.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-2As shown, a rechargeable battery has an external housing 100 made of high-strength polycarbonate material housing shell 110. The internal removable lithium-ion battery is tightly engaged with the slot in the housing through the concave-convex buckle structure on the shell. The stable installation method avoids interference with voltage output caused by battery shaking. The rechargeable battery 200 is equipped with a universal Type-C charging interface 300 at the end, exposed at the opening 120 of the rechargeable battery 200, which ensures the convenience of external charging while also ensuring stable power transmission during charging and output.

[0028] The conversion circuit module 400 is integrated onto a small PCB. Its internal buck chip uses pulse width modulation (PWM) technology to dynamically adjust the output pulse width based on the real-time battery output voltage and load conditions. For example, when the battery power decreases and the output voltage drops, the buck chip quickly increases the pulse width to boost the output voltage; if the load increases and causes a voltage drop, the chip adjusts accordingly to ensure stable output voltage. Simultaneously, filter capacitors and inductors work together to deeply filter the voltage output by the buck chip. The filter capacitors quickly absorb high-frequency noise in the voltage, while the inductors smooth the voltage curve and eliminate low-frequency ripple through electromagnetic induction. Together, they precisely stabilize the battery output voltage at 3±0.1V, providing reliable power support for devices with high voltage stability requirements, such as smart wearables and portable electronic instruments. When connected to an external power source for charging, the module automatically enters a sleep state to avoid interfering with the charging process, ensuring a safe and efficient charging experience. It not only adapts to various voltage-sensitive devices but also effectively extends device lifespan and reduces the risk of device failure due to voltage instability.

[0029] like Figure 3-4 As shown, the rechargeable battery 200 provided in this application can first be charged through the charging compartment 800. The charging compartment 800 includes a first housing 500 and a second housing 600 that are movably connected. The first housing 500 of the rechargeable battery 200 is provided with a charging base 700, and the charging base 700 of the rechargeable battery 200 is provided with at least one charging compartment 800. The second housing 600 of the rechargeable battery 200 is provided with a conductive device 900. The conductive device 900 of the rechargeable battery 200 corresponds one-to-one with the charging compartment 800 of the rechargeable battery 200. The figure shows eight charging compartments 800 and eight conductive devices 900. This number can be selected by the user.

[0030] The conductive device 900 contains a metal conductive sheet. When the rechargeable battery 200 needs to be charged, the first box 500 and the second box 600 are closed, and the metal conductive sheet acts as a conductor to conduct current to the rechargeable battery 200 in the battery compartment.

[0031] Furthermore, when the second housing 600 of the rechargeable battery 200 is closed on the first housing 500 of the rechargeable battery 200, the conductive device 900 of the rechargeable battery 200 is electrically connected to the rechargeable battery 200 to be charged inside the first housing 500 of the rechargeable battery 200. It also includes a fixing device 1000 disposed inside the first housing 500 and the second housing 600 of the rechargeable battery 200. The fixing device 1000 consists of two magnets, which are respectively disposed inside the first housing 500 and the second housing 600. When the first housing 500 and the second housing 600 are closed, the edges of the first housing 500 and the second housing 600 are snapped together by their own elasticity. The two magnets make the fixation more reliable and ensure the stability of the electrical connection.

[0032] In addition, such as Figure 5 As shown, the rechargeable battery 200 provided in this application can also be charged via an external USB connection, which is more convenient and faster.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
