Abstract

The present invention relates to a building block type mobile power device and the charging component. The building block type mobile power device comprises a housing, a first combining part, a second combining part, a male connector, a female connector, a battery, and a battery chip. The battery is located within the housing. The battery chip is also located within the housing and is electrically connected to the male connector, the female connector, and the battery. The battery chip has a charging and discharging threshold, which determines whether the battery should be discharged or charged based on the voltage or current of the male and female connectors. Specifically, when the battery chip is electrically connected to a discharge terminal of another mobile power device with a modular assembly structure through the female connector, the battery is not charged. Therefore, this design allows for an increased total power supply capacity by connecting multiple devices in series and enables simultaneous charging of multiple terminal devices.

Description

Building block type mobile power device and its charging assembly

This invention is about a mobile power device and its charging assembly, in particular about a building block type mobile power device and its charging assembly.

A power bank is a portable charger that can be carried around, store electricity, and charge terminal devices such as handheld mobile devices. It is particularly suitable for use in situations where there is no external power supply or the location needs to be constantly moved. Currently, the energy density of portable batteries is fixed. If a large-capacity power bank is selected to increase the power supply, its weight and size will also be considerable and difficult to carry. If the power bank is only needed for a short time, it is not suitable to carry the large-capacity power bank. In other words, the commonly used power banks cannot adjust the storage density and weight according to different usage times. In addition, the same power bank cannot provide charging for multiple terminal devices at the same time.

To solve the above problem, the conventional technology, such as announcement No. M522505, discloses a serial mobile power structure, including a main mobile power and at least one supplementary power. The main mobile power has a first rated capacity, the supplementary power has a second rated capacity, and a plurality of supplementary power are connected in series to the main mobile power to expand the total capacity of the serial mobile power structure. Announcement No. M450131 discloses a mobile power supply device having a mobile power main body component, the mobile power main body component includes a housing, a cover, a USB power supply connector and a USB power serial connector, the housing has a battery storage space to accommodate a battery, the cover is arranged on the housing to cover the upper side of the battery storage space of the housing, the USB power supply connector is arranged on the housing, so that the mobile power supply device can provide power to the mobile device at any time, and the USB power serial connector is arranged on the housing, and can be connected in series with multiple power supply devices, providing a mobile power supply device that can be expanded by serial connection for use by the mobile device, so that the working time of the mobile device is extended.

However, both of the above-mentioned known technologies require a mother device as the terminal for battery charging and discharging. Although the mother device itself has the battery charging and discharging function, the other sub-devices, although they have battery functions, cannot be used alone. They all need to be connected to the mother device, and then discharge the electronic products of the terminal device and charge the sub-devices through the charging and discharging interface of the mother device. Therefore, there are inconveniences in use. For example, for a set of mother and child devices as a whole, it is often impossible for each sub-device to charge (or discharge) each battery at the same time.

To solve the above problems, there are other conventional technologies such as application No. 102135109, which is a mobile power supply using a serial design, suitable for providing a discharge voltage to charge an electronic product, and includes a plurality of rechargeable batteries and a voltage regulating circuit. The batteries are connected in series between a first battery terminal and a second battery terminal. The voltage regulating circuit is electrically connected to the first battery terminal and the second battery terminal, receives the voltage difference between the first battery terminal and the second battery terminal, and provides the electronic product with the discharge voltage after reducing the voltage. By arranging the batteries in series and using the voltage regulating circuit for voltage reduction output, the current burden during charging and the danger of use can be reduced, and better energy utilization can be obtained.

However, the aforementioned application technology still focuses on solving the problem of heating caused by the exponential increase in charging current when the number of batteries connected in series increases, and obtaining better energy utilization, but this application technology also cannot separate the series-connected batteries and charge multiple electronic products separately.

In view of the above and other problems, the prior art needs to be improved.

Without departing from the spirit of the creation, this creation has multiple implementation methods and is not limited to the details specifically described in the implementation methods below. The drawings may not be drawn according to the actual scale and are only provided for illustrating the embodiments.

FIG. 1 is a three-dimensional diagram of a mobile power device with a building block assembly structure according to an embodiment of the present invention, and FIG. 2 is a system architecture diagram of a mobile power device with a building block assembly structure according to an embodiment of the present invention.

The male connector 20 is disposed on the housing 10, and its interface specifications include Type C, micro usb or light male connectors. The female connector 30 is disposed on the housing 10, and can be, for example, a female connector with an interface specification of the same transmission protocol as the male connector 20.

The battery 40 is disposed in the housing 10. The battery chip 50 is also disposed in the housing 10 and electrically connects the male connector 20, the female connector 30 and the battery 40. The battery chip 50 can set a charge and discharge threshold 51 to set a critical value for the charge and discharge of the battery 40. For example, the battery chip 50 is based on the electrical connection between the male connector 20 and the female connector 30.

When the female connector 30 is electrically connected to a discharge terminal of another mobile power device with a building block assembly structure (e.g., the same structure as the male connector 20), the battery 40 can be determined not to be charged based on the charge and discharge threshold 51, thereby avoiding unnecessary power transmission and loss.

It is worth mentioning that a power indicator 13 can be provided at a prominent position of the housing 10, and the power indicator 13 is electrically connected to the battery chip 50 to display the current power of the battery 40.

By connecting the second coupling member 12 of the mobile power device 1 with a building block assembly structure and the first coupling member 11′ of the mobile power device 1′ with a building block assembly structure, the mobile power device 1 with a building block assembly structure and the mobile power device 1′ with a building block assembly structure are structurally firmly coupled to form an integral body. At the same time, due to the structural design, the two mobile devices (the mobile power device 1 with a building block assembly structure and the mobile power device 1′ with a building block assembly structure) are connected to each other. The male connector 20' of the mobile power device 1') is also plugged into the female connector 30 to be electrically connected, and during the electrical connection between the male connector 20' and the female connector 30, the battery chip 50 of the mobile power device 1 with a building block assembly structure uses the charge and discharge threshold value 51 to determine that the battery 40 is not being charged. Similarly, the battery chip 50' of the mobile power device 1' with a building block assembly structure uses the charge and discharge threshold value 51' to determine that the battery 40' is not being discharged.

Each of the battery chips (50, 50') has a charge and discharge threshold (51, 51') to judge whether to discharge or charge the battery (40, 40') according to the voltage or current of the male connector (20, 20') and the female connector (30, 30'). When each of the male connectors (20, 20') is connected to a charging hole of a terminal device (M1, M2), it is judged whether the battery (40, 40') is discharged or charged. By combining the first coupling member 11' with the second coupling member 12, the first mobile power device 1a of the charging assembly is connected in series with the second mobile power device 1a', and the male connector 20' is structurally connected and electrically connected to the female connector 30. The battery chip 50 of the first mobile power device 1a is charged with the voltage of the battery 40' of the second mobile power device 1a' or The battery 40 of the first mobile power device 1a is judged not to be charged according to the corresponding charge and discharge threshold value 51, and/or the battery chip 50' of the second mobile power device 1a' uses the voltage or current of the battery 40 of the first mobile power device 1 to judge not to be discharged according to the corresponding charge and discharge threshold value 51'.

It is worth noting that in the above-mentioned charging assembly, when one mobile power device is low on power or out of power, the mobile power device can be charged separately without affecting the continued use of the other mobile power device, thereby increasing the efficiency and convenience of use. Preferably, the charging assembly of the present invention may further include the protective cover 60, which is sleeved on the top layer of the charging assembly (i.e., the first mobile power device 1a), and the third coupling member 62 of the protective cover 60 is coupled to the first coupling member 11, so that the accommodating space 61 covers and protects the male connector 20.
