Description

A mobile power source

Technical Field

The utility model relates to the technical field of mobile power supplies, in particular to a mobile power supply.

Background Art

A power bank, also known as a mobile power source, is a portable charger that can be carried around by an individual and can store electrical energy. It is mainly used to charge consumer electronic products such as handheld mobile devices. It is particularly used in situations where there is no external power supply. However, there are still many problems with the use of existing power banks. For example, when the power bank runs out of power and needs to be recharged, an external charger is required to charge it, which makes it inconvenient to use. On the other hand, since the chargers for charging the power bank are all found by users temporarily, this may cause the power supply to be incompatible, resulting in damage to the charging of the power bank, which in turn leads to a decrease in its service life. Therefore, it is necessary to propose improvements to the existing technology.

The mobile power supply of the preferred embodiment of the utility model, as shown in Figures 1-3, includes a bottom shell 10 and a mask 20 covered on the bottom shell 10. The bottom shell 10 and the mask 20 enclose a mounting cavity. The power supply also includes a first PCB board 30 arranged in the mounting cavity. A power supply compartment 40 is provided in the mounting cavity, and a high-voltage compartment 50 and a low-voltage compartment 60 are respectively provided at two opposite ends of the power supply compartment 40. A partition 70 is provided between the low-voltage compartment 60 and the high-voltage compartment 50 and the power supply compartment 40. The power supply also includes a power pin 80 telescopically arranged in the high-voltage compartment 50, and a battery 90 arranged in the power supply compartment 40. It should be noted that the telescopic structure of the power pin 80 is an existing conventional technical means, and this solution will not be repeated here. The battery 90 is electrically connected to the power pin 80 through the first PCB board 30 to realize charging of the battery 90 when the power pin 80 is inserted into the socket. Furthermore, the mask 20 or the bottom shell 10 is provided with a charging port 100 for the power pin 80 to extend, so that the power pin 80 can be extended when in use and retracted when not in use for easy storage. Among them, the mask 20 or the bottom shell 10 is provided with a window 120 for the power output line 110 to pass through corresponding to the first PCB board 30, so as to set the power output line 110, so as to facilitate users to charge mobile phones and other electronic devices.

The present solution uses a built-in power pin 80, which can be extended at any time to be inserted into the battery 90 on the socket strip for charging, thereby avoiding the battery life being affected by the mismatch of the charging head arbitrarily configured by the user; and during normal use, the power pin 80 is stored in the high-voltage compartment 50 to avoid the inconvenience caused by the power pin 80 being stored again; in addition, the power inductor can be placed in the low-voltage compartment 60, and the transformer and other components can be placed in the high-voltage compartment 50, so that the power components that generate heat in the high-voltage compartment 50 and the low-voltage compartment 60 are placed separately, which will not cause heat concentration and affect the heat dissipation effect, and the battery 90 and each component are fixed separately, which can improve the overall impact resistance of the power supply.

In this embodiment, the bottom shell 10, the mask 20, the first PCB board 30 and the installation cavity are all in the shape of long strips, so that the user can hold it with one hand. Specifically, in order to further improve the comfort, the outer side of the mask 20 is arc-shaped. The power supply compartment 40, the high-voltage compartment 50 and the low-voltage compartment 60 are all directly opposite to the first PCB board 30. The first PCB board 30 is provided with a high-voltage area and a low-voltage area corresponding to the high-voltage compartment 50 and the low-voltage compartment 60. The high-voltage area is used to install high-voltage components such as transformers, and the low-voltage area is used to install components working under the voltage after the voltage is stepped down. The first PCB board 30 covers the three compartments as a whole, and the area of the first PCB board 30 is increased, which can achieve the effect of heat dissipation. Among them, the high-voltage compartment 50 and the battery compartment are isolated by the partition for high voltage, and the battery compartment and the low-voltage compartment 60 are also provided by the partition for pressure strength to prevent impact. Moreover, the first PCB board 30 is placed on the top of the battery, so that the height of the transformer and the battery in the high-voltage compartment 50 can be the same, and the height size is not repeated, which effectively reduces the volume. In addition, the first PCB board 30 completely covers the three compartments, the low-voltage compartment 60 is used to place the power inductor, and the power components that generate heat in the high-voltage compartment 50 and the low-voltage compartment 60 are placed separately, which will not cause heat concentration and affect the heat dissipation effect.

An external power output line 110 is placed in the low-pressure compartment 60, and the other end of the fast-charging line is plugged into the mask 20, which does not occupy the main body space and effectively reduces the product volume.

In this embodiment, the window 120 is provided on the mask 20 and is located on the side of the low-voltage compartment 60 away from the power compartment 40, so that the distance between the power output line 110 and the power pin 80 is maximized to ensure the safety of charging.

In this embodiment, the power supply further includes a second PCB board 160 vertically arranged in the high-voltage chamber 50, and a first mounting position 161 for mounting the transformer 200 is provided on the second PCB board 160 above the power pin 80, and second mounting positions 162 for mounting the capacitor 300 are provided on the second PCB board on both the left and right sides of the first mounting position 161. By arranging the second PCB board 160 to mount the transformer and the capacitor, the capacitor is horizontally arranged, so as to make full use of the space above and on the left and right sides of the power pin 80, so that the assembly of each component is more compact, so as to further reduce the overall volume of the power supply.

In this embodiment, the first PCB board 30 and the second PCB board 160 are detachably connected to facilitate assembly and separate processing.

In this embodiment, the partition 70 is disposed on the bottom shell 10, and the first PCB board 30 is disposed between the partition 70 and the mask 20 and is detachably connected to the partition 70 to ensure the stability of the first PCB board 30 and also facilitate the early assembly and processing operations.

In this embodiment, a transparent cover 130 is provided on the outer wall of the mask 20 to enhance the aesthetics of the product.

In this embodiment, an active button 140 is provided on the mask 20 corresponding to the switch 301 on the first PCB board 30 to facilitate the user to turn on the power when charging the external electronic device, wherein an avoidance hole 150 is provided on the transparent cover 130 corresponding to the active button.
