Description

Technical Field

[0001] The utility model relates to the technical field of portable charging equipment, in particular to a mobile power source for charging electronic products. Background Art

[0002] A mobile power bank (power bank) is a device that can charge mobile devices and has its own power storage unit. It has the characteristics of USB output, large power capacity and good portability, and is widely used in mobile charging of digital products such as mobile phones, MP3, MP4 and PSP.

[0003] In the prior art, mobile power banks with a capacity of more than 20,000 mAh are generally large in size and still inconvenient to carry. In addition, most of the existing mobile power banks on the market do not have a device to prevent accidental touch. If a user touches the mobile power bank by mistake, it is easy to cause power loss and waste electricity. In addition, in the prior art, mobile power banks of different capacities usually require molds of different sizes, and one mold only corresponds to one mobile power bank, which has high development and production costs.

[0004] Some existing power bank technologies can be found in patent documents such as publication number CN106451672A, CN106208232A, and announcement number CN212114819U. Summary of the invention

[0005] The purpose of the utility model is to provide a mobile power supply structure that is universal and good for production molds, and to at least provide a beneficial choice or create conditions for solving one or more technical problems existing in the prior art.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions.

[0007] A mobile power supply comprises a shell, a top cover, a bottom cover, a circuit board assembly and a battery assembly, wherein the shell is a cavity structure penetrating from top to bottom, the top cover and the bottom cover are respectively mounted on the two end openings of the shell, and the circuit board assembly and the battery assembly are mounted in the shell; the shell is a columnar cavity penetrating from top to bottom, and has a consistent shape from top to bottom; the periphery of the top cover extends upward to form a suspension frame, and a switch button of the mobile power supply is located in the area surrounded by the suspension frame.

[0008] More preferably, the circuit board assembly is arranged close to the end where the top cover is located, and the top of the shell is inclined with one end higher than the other.

[0009] More preferably, a gap is left between the suspension frame and the top cover.

[0010] More preferably, the shell is made of aluminum alloy, stainless steel or copper.

[0011] More preferably, the charging port of the mobile power supply is arranged in the area enclosed by the suspended frame on the top cover and / or on the shell and / or on the bottom cover.

[0012] More preferably, the battery assembly is composed of a plurality of vertically placed cylindrical batteries.

[0013] More preferably, the battery assembly is composed of four cylindrical batteries, and the four cylindrical batteries are arranged in a row, two by two, and are staggered and tightly attached.

[0014] More preferably, the top cover and the bottom cover are locked and fixed by a plurality of screws penetrating the inner cavity of the shell.

[0015] More preferably, a functional accessory is nested and installed between the top cover and the shell, and the functional accessory and the circuit board assembly are used to realize wireless charging, flashlight or night vision light functions.

[0016] More preferably, the functional component is a watch wireless charger.

[0017] More preferably, the functional component is a ring-shaped light bar.

[0018] The technical solution provided by the utility model has at least the following technical effects or advantages.

[0019] 1. Convenient production and low production cost. Since the shell is a cylindrical cavity that runs through from top to bottom, the internal space of the mobile power supply can be increased or decreased by changing the height of the shell according to the different battery capacity of the mobile power supply or the number of layers and height of the circuit board assembly. The shell molds of mobile power supplies of different capacities can be universal, and the sizes of the top cover and bottom cover are not affected, saving costs and time for developing new molds, making the factory more flexible in production and greatly reducing production costs.

[0020] Second, since the circuit board assembly is arranged near the end where the top cover is located, and the top of the shell is inclined with one end higher than the other, when arranging the electronic components on the circuit board assembly, the larger components can be placed at the higher end, thereby making the best use of the entire design space and avoiding waste.

[0021] 3. Reduce accidental touches. When the mobile power bank is placed in a backpack together with other items, the suspension frame can prevent other items in the backpack from pressing the switch button, reducing the loss of power due to accidental touch of the switch button.

[0022] 4. Easy to hang and carry. Since there is a gap between the suspension frame and the top cover, users can put a carabiner in the middle of the gap or hold it with their fingers, making it more convenient to carry the mobile power bank.

[0023] 5. Reduce the damage of the mobile power supply when it falls to the ground. When the mobile power supply falls to the ground, if it falls with the top cover downward, it will cause a greater impact on the circuit board components, making the mobile power supply easy to damage. The suspension frame can enhance the buffer, allowing the mobile power supply to withstand part of the impact when it falls, reducing the chance of damage when the mobile power supply falls to the ground.

[0024] 6. Convenient for function expansion. By nesting functional accessories between the top cover and the shell, the expansion of functions such as wireless charging, flashlight or night vision light can be realized, making the mobile power supply more functional.
