Description

Technical Field

[0001] This utility model relates to the technical field of mobile batteries, specifically to mobile batteries with switches.

Background Art

[0002] Portable mobile batteries, as movable power storage devices, are widely used in various power supply scenarios for mobile electronic devices due to their convenience. Many existing portable mobile batteries adopt a direct connection circuit design and do not have an individually provided switch to control on and off. Therefore, the end of their power supply interface is always in an energized state. During daily portability, mobile batteries are often placed in backpacks, pockets, etc., and are likely to come into contact with metal parts such as necklaces and keys, which may cause circuit short circuits. This not only causes battery damage and rapid power loss of the mobile battery, but may also cause situations such as high temperature, heat generation, and even ignition due to the short circuit, posing a serious safety risk. At the same time, the always-on circuit causes the self-discharge problem of the battery, shortening the driving time and service life of the mobile battery. Although some existing similar products have added a protection structure for the interface, they do not solve the core problem of energized short circuit from the circuit on and off level, and it is difficult to meet the safe use needs of users for portable power storage devices.

Summary of the Invention

[0003] The purpose of this utility model is to provide a mobile battery with a switch in order to solve the problems raised in the above-mentioned background art.

[0004] To achieve the above objective, this utility model provides the following technical solution: A mobile battery with a switch, comprising an outer casing, the upper part of the outer casing connected to an inner cover, the bottom of the outer casing connected to a bottom cover, a battery installed inside the outer casing, a top cover fitted to the outside of the inner cover, a mounting block provided inside the inner cover, a circuit board connected to the bottom of the mounting block, a socket and a switch component provided on both sides of the circuit board, two contact poles installed at the bottom of the circuit board, and the contact poles connected to the battery.

[0005] As an excellent design, a sealing lid plate is attached to the top of the internal cover, and the bottom of the internal cover is screwed to the upper inner wall of the outer shell.

[0006] As a good design, the bottom cover and the bottom of the outer shell are connected by screws.

[0007] As an excellent design, two rectangular grooves are provided on the side walls of the internal cover and the mounting block, and the socket and switch components are located within these rectangular grooves.

[0008] As a good design choice, the top lid and the inner cover are fastened together with internal and external threads.

[0009] A good idea would be for the aforementioned connector to be a Type-C interface.

[0010] A good idea is that the switch component is used to switch the open / closed state of a circuit within a circuit board. [Effects of the Invention]

[0011] Compared to conventional technology, the beneficial effects of this utility model are as follows: This mobile battery with a switch actively controls the opening and closing of the circuit by adding a switch component to the circuit board. Since the circuit is shut off when not in use, it completely avoids short-circuit problems caused by the energized state of the interface terminals and contact with metal parts, significantly improving safety during use and portability. The device uses screw connections for both the top cover and inner cover, and the bottom cover and outer casing, making them easy to remove and providing high protection, effectively protecting the socket and internal components. The contact pole ensures a stable electrical connection between the battery and the circuit board, and the Type-C socket offers high compatibility. Furthermore, the controllable opening and closing of the circuit reduces unnecessary self-discharge of the battery, extending its lifespan. The overall structure is compact, optimizing safety performance without compromising the product's portability and ease of use. [Brief explanation of the drawing]

[0014] The following describes the technical method of the embodiments of this utility model clearly and completely, using drawings of the embodiments. Clearly, the embodiments described are only a part of, and not all of, the embodiments of this utility model. All other embodiments that can be obtained by a person skilled in the art without creative work based on the embodiments of this utility model are within the scope of protection of this utility model.

[0015] Please refer to Figures 1 to 5. This utility model provides the following technical solution: A mobile battery with a switch, comprising an outer casing 1, the upper part of the outer casing 1 being connected to an inner cover 4, the upper part of the inner cover 4 being connected to a sealing lid plate, and the bottom of the inner cover 4 being screwed to the upper inner wall of the outer casing 1. A bottom cover 3 is connected to the bottom of the outer casing 1, and the bottom cover 3 and the bottom of the outer casing 1 are connected by screws.

[0016] A battery 8 is installed inside the outer casing 1, and the battery 8 is a lithium battery. A top cover 2 is fitted to the outside of the inner cover 4, and the top cover 2 and the inner cover 4 are screwed together with internal and external screws. The top cover 2 can be closed when not in use, and removed when charging is required. A mounting block 5 is provided inside the inner cover 4, and a circuit board 9 is connected to the bottom of the mounting block 5. On both sides of the circuit board 9 are sockets 6 and switch components 7. Socket 6 is a Type-C interface and is for charging using a data cable. Two rectangular grooves are provided on the side walls of the inner cover 4 and the mounting block 5, and the sockets 6 and switch components 7 are located within these rectangular grooves. Two power supply poles 10 are installed at the bottom of the circuit board 9, and the power supply poles 10 are electrically connected to the battery 8.

[0017] The switch component 7 is used to switch the open / closed state of the circuit in the circuit board 9. The internal structure of the switch component 7 is as shown in Figure 5, and the exterior of the switch component 7 is made of flexible rubber. Inside the switch component 7 are a cover plate 701, a button 702, a spring plate 703, a base 704, and function pins 705. The base 704 is mounted on the circuit board 9, and the two function pins 705 are connected to the open ends of the circuit, respectively. In the initial state of the device, the switch is in the off position, and the circuit is not open or closed. When the button 702 is pressed downwards, the spring plate 703 deforms and contacts the function pins 705 at the bottom, connecting the function pins 705 at both ends and turning the circuit on, connecting the battery 8 and the socket 6. When the hand is released from the button 702, the spring plate 703 returns to its original state and separates from the function pins 705, and the circuit is disconnected. By providing the switch component 7, the device can shut off the circuit itself, preventing short circuits from occurring even when in contact with metal, thus increasing safety.

[0018] The mobile battery with a switch disclosed in this utility model is a portable energy storage device optimized to address the safety issues of conventional portable mobile batteries. The main support structure consists of an outer shell 1, connected to a bottom cover 3 by screw connections at its base. Inside, a battery 8 is housed to supply power, and an internal cover 4 is screwed to the top. A top cover 2, which can be twisted off, is fitted to the outside, forming a double protective structure. A mounting block 5 is provided inside the internal cover 4, and a circuit board 9 connected to its bottom is the core control component. On both sides of the circuit board 9, a Type-C socket 6 and a switch component 7 are installed in corresponding square grooves, and the bottom is electrically connected to the battery 8 via two contact poles 10. The addition of the switch component 7 allows for flexible adjustment of the circuit's opening and closing, fundamentally solving the problem of short circuits. At the same time, the screw connection design of each component makes removal and maintenance easy, resulting in a rational overall structure that combines safety, portability, and practicality.
