Description

Variable structure portable power supply

The present invention relates to a portable power supply of a variable structure, and more particularly to a power supply that forms a variable structure by a change in relative position between a plurality of housings.

Thanks to the advancement of science and technology, related consumer electronic products are getting smaller and more powerful, and they are derived from consumer electronics such as mobile phones, MP3 players, handheld game consoles, but not only The phone can also include digital cameras, MP3 and other functions, while MP3 players and handheld game consoles can be used with large screens to further play movies and other functions. All powerful practical and entertainment functions are included in the same electronic product. Inside, and most importantly, the volume of consumer electronics is still getting smaller and smaller and easier to carry around.

However, in the trend of smaller portable portable electronic products and more powerful functions, it is inevitable to increase the design difficulty of batteries in consumer electronic products, because the powerful function represents a large power consumption, and the small size represents the battery. The volumetric capacity is inevitably small, so portable consumer electronic products usually have to be charged regularly and frequently, making it difficult for consumer electronic products to be used anytime, anywhere in an environment where power supply is inconvenient and for a long time. Charging often causes power to run out and does not work. In view of this, various portable power supplies have been gradually derived as spare or extended power supply devices for consumer electronic products in addition to general indoor power.

The conventional portable power supply includes at least a control circuit and a battery, by which the input power for charging the battery and the power output by the battery can be controlled, and the portable power supply architecture is generally All components are installed in a hollow casing. Therefore, the portable power supply casing structure seen on the market mostly has a square appearance. If the casing structure is to be changed, it is only limited to the outer casing structure. Size, thickness change only. Therefore, the nearly standardized housing structure of the portable power supply is often difficult to match with the versatile and personalized consumer electronic products, and the constant appearance also makes the user feel the cold and a sense of distance to carry. Convenience, the square casing that is not changed, if it must be accommodated in a limited space, often causes inconvenience in storage.

In summary, there is an urgent need for a portable power supply that is more suitable for storing and carrying, and can be changed to a different housing appearance to fit different storage spaces without affecting the power supply function.

The main purpose of the present invention is to make up for the needs of the conventional portable power supply, and to provide a changeable housing structure, so that the portable power supply device presents different appearances and is more convenient for the user to carry.

To achieve the above object, the present invention includes at least one energy storage component, at least one control circuit electrically connected to the energy storage component, and a housing accommodating the energy storage component and the control circuit, characterized in that The housing includes a first housing and a second housing forming two accommodating spaces, and respectively accommodating one or a combination of the energy storage component and the control circuit, the first and second housing phases The adjacent sides are respectively a first contact side and a second contact side, and the first and second contact sides have a corresponding pivot hole, and the pivot hole is provided with a receiving space in the first and second housings The hollow shaft is connected to the pivot hole and forms a rotational displacement relationship. The above is the basic structure of the present invention, wherein the first and second contact sides may be provided with corresponding magnets to provide the first and second The positioning force of the housing at different positions.

With the above technical solutions, the present invention has at least the following advantages over the prior art:

1. The conventional portable power supply cannot escape the inherent thinking of the internal circuit structure, so that the outer casing structure of the portable power supply is limited to a single casing and a single accommodating space, and the present invention breaks through the conventional viewpoint. The housing of the portable power supply can be changed in different structures according to different needs and is more portable.
2. In addition to utilizing the variable structure to increase the portability, the present invention further increases the space of the design of the portable power supply, so that the portable power supply can exhibit different styles of appearance and is more attractive to users. Favor.
