The present invention will now be described in more detail with reference to the accompanying drawings, and it is to be understood that the following description of the present invention is made only by way of illustration and not by way of limitation with reference to the accompanying drawings. The various embodiments may be combined with each other to form other embodiments not shown in the following description.

Example one

The embodiment provides a mobile power supply device, and aims to solve the problem that the interface function of the existing mobile power supply device is single. Specifically, referring to fig. 1 and 2, the mobile power supply device includes a housing 10, where the housing 10 includes a battery pack 20, a battery management module 30, a first interface 40, and a second interface 50, where the battery pack 20 is disposed inside the housing 10, and the first interface 40 and the second interface 50 may be embedded in a surface of the housing 10.

The outer surface of the case 10 may be formed in a rectangular parallelepiped shape or a cylindrical shape, and the shape is not limited, but it is preferably formed in a rectangular parallelepiped shape so as to accommodate the battery pack 20.

The battery pack 20 is a combination of a plurality of batteries. The cells are generally arranged in a direction perpendicular to the axis of the cell pack 20 for the sake of space occupation and portability, and the number of the cells may be adjusted according to practical situations, and is not limited herein.

The battery management module 30 is electrically connected to the battery pack 20, and serves to manage input and output of the battery pack 20 and protect the battery pack 20. Specifically, the battery management module 30 includes a battery protection chip electrically connected with the battery pack 20, a charging unit, and a discharging unit electrically connected with the battery protection chip. The battery pack 20 is monitored by the battery protection chip, and the battery protection chip also has the advantages of avoiding overload, overvoltage and electric leakage.

The first interface 40 is adapted to an electric energy input end of the 3C electronic product, and the first interface 40 is electrically connected to the charging unit, so that the battery pack 20 provides direct current to the 3C electronic product through the battery protection chip, the discharging unit and the first interface 40, wherein the position of the first interface 40 is not limited, and can be adjusted according to actual conditions. The first interface 40 is further adapted to an electric energy output end of the external power source, and the first interface 40 is further electrically connected to the charging unit, so that the external power source can charge the battery pack 20 through the first interface 40, the charging unit, and the battery protection chip. The first interface 40 realizes the functions of charging and discharging, so as to increase the interface diversity of the mobile power supply device; the number of interfaces is reduced to a certain extent so as to reduce the structural complexity of the mobile power supply device.

It should be noted that the first interface 40 is adapted to the 3C electronic product/external unit, which is adapted to voltage, and the connection manner is not limited to plugging or connecting via a connecting wire. The first discharging interface 401 at least includes a USB-a interface and/or a USB-C interface to meet the power input type requirement of the existing 3C electronic product.

The second interface 50 is adapted to the power input of the power tool. It should be noted that the term "adapting" herein refers to adapting to a voltage, and the connection manner is not limited to plugging or via a connecting wire. It is understood that the electric tool is not limited to the cordless hand-held electric tool, but includes power working devices such as garden tools, cordless vacuum cleaners, and dc air compressors which use a secondary battery as a power source.

Taking a rectangular parallelepiped as an example, a surface perpendicular to the battery axis direction is a side surface a, and a surface perpendicular to the battery laying direction is a side surface b. Since the output end of a part of the power tool is usually disposed on the side surface thereof, the second interface 50 may be installed on the side edge a and the side surface b, and the output end of the power tool is preferably directly engaged with the second interface 50, so that the bottom of the power tool and the bottom of the housing 10 can be stably placed on a table when the power tool is charged.

As an optional technical solution, the housing 10 is further provided with a locking structure, and when the power tool is fittingly connected with the mobile power supply device, the locking structure is used for locking the power tool on the housing 10. Specifically, the locking structure may employ a latch and a latch hole, one of which is mounted on the housing 10 and the other of which is mounted on the power tool. When the output end of the power tool is directly engaged with the second interface 50, the latch and the latch hole are correspondingly locked, so that the power tool is prevented from being separated from the mobile power supply device during charging.

As an optional technical solution, the mobile power supply device further includes a wireless charging receiver 60 and a wired charging interface, the wireless charging receiver is disposed inside the casing 10, the display module 90 may be disposed on the surface of the casing 10, and the wired charging interface 70 may be embedded on the surface of the casing 10.

The controller 80 is also connected to the wired charging interface 70, the wireless charging receiver 60 and the first interface 40, so as to select the priority. For example: when the wired charging interface 70 is of the first priority, the wireless charging receiver 60 is of the second priority, and the first interface 40 is of the third priority, the wireless charging receiver 60 and the first interface 40 are controlled to stop charging when the wired charging interface 70, the wireless charging receiver 60 and the first interface 40 are simultaneously charged, so that the mobile power supply device only enters a corresponding charging mode.

The controller 80 is also electrically connected with the battery protection chip to calculate the power condition of the battery pack 20; the controller 80 is further electrically connected to the display module 90, and is configured to receive and display a calculation result of the controller 80, that is, display the current power condition of the battery pack 20 on the display module 90, so that a user can know the power condition of the portable power supply device in real time. For example, the display module 90 may be a plurality of LED lamps, and the controller 80 realizes the display of the electric quantity by controlling the lighting number of the LED lamps, and of course, the controller 80 may also be a display screen, and the controller 80 controls the percentage of the electric quantity displayed on the display screen to realize the display of the electric quantity. It should be noted that the display module 90 is not limited to displaying the power level of the battery pack 20, and can also be used to display the charging/discharging state of the portable power device.
