Description

Technical Field

[0001] The utility model relates to a portable charger combination. Background Art

[0002] A mobile power bank is a portable device that can charge or power digital devices such as mobile phones anytime and anywhere. It is generally equipped with lithium batteries as power storage units and multiple mainstream power supply sockets such as USB and TYPE-C. Currently, most mobile power banks do not have dedicated chargers. They are charged through charging cables and mobile phone chargers, which will take up the charging time of the mobile phone and affect user use. Occasionally, there are devices that integrate mobile power banks and chargers. Although this solves the charging problem of mobile power banks, it also makes the mobile power banks too large and heavy, inconvenient to carry, and causes trouble for users. Utility Model Content

When charging, the second body is connected to the electrical contact part of the first body. At the same time, the first body is also provided with a power supply socket to meet the charging needs of other electronic products such as mobile phones, overcoming the defect that traditional products have a monopoly on charging cables when charging; when the user goes out, the second body can be taken away without affecting the continued charging of other electronic products.

[0034] This product is designed with a first main body 1 (equivalent to a charger) and a second main body 2 (equivalent to a mobile power source) that can be combined and detached, so as to solve the problems of charging connection and carrying. When charging, the second main body 2 is docked with the first main body 1. At the same time, the first main body 1 is also provided with a first power supply socket 12 to meet the charging needs of other electronic products such as mobile phones, thereby overcoming the defect that traditional mobile power products exclusively occupy the charging line when charging, and also avoiding the trouble that users need to carry chargers for mobile power sources and mobile phones separately; when the user goes out, the second main body 2 can be taken away without affecting the continued charging of other electronic products. The second main body 2 does not need to be accompanied by a charger structure, so its volume and weight will be controlled, and the structure of the second main body 2 has a larger design space.

[0035] Specifically, the first main body 1 is provided with a first circuit board 13, a charging plug 14 and a first wireless charging module 15, the electrical input end of the first circuit board 13 is connected to the charging plug 14 to obtain city power, and the electrical output end of the first circuit board 13 is respectively connected to its first electrical contact portion 11, the first power supply socket 12 and the first wireless charging module 15; the first circuit board 13 is provided with an AC-DC transformer circuit of a conventional charger, which transforms the 220V city and provides a +5V DC voltage to the first electrical contact portion 11 and the first power supply socket 12; the second main body 2 is provided with a second circuit board 23, a battery 24 and a second wireless charging module 25, the second circuit board 12 is provided with a power management circuit of a conventional mobile power supply to realize charging and discharging management, the second circuit board 23 is connected to the battery 24 to charge / discharge the battery 24, the electrical input end of the second circuit board 23 is connected to its second electrical contact portion 21, and the electrical output end is connected to the second power supply socket 22 and the second wireless charging module 25. The first body 1 and the second body 2 are respectively provided with wireless charging modules, and both can wirelessly charge the adapted electronic products separately, thereby improving the versatility of the charger combination.

[0036] Taking into account the charging scenario and the stability of docking, the first body 1 and the second body 2 are combined in a stacked manner, that is, the first body 1 is first connected to the socket, and then the second body 2 is stacked on the first body 1, and electrical contact parts of male and female plug-in structures are respectively provided on the contact surfaces of the two shells, and the first electrical contact part 11 of the first body 1 is a convex column on its shell, and the second electrical contact part 21 of the second body 2 is a groove on its shell, and a first electrode 111 for electrical contact is provided on the convex column, and a second electrode 211 for electrical contact is provided on the groove. In addition, magnetic blocks 3 with opposite positions are respectively provided in the first body 1 and the second body 2. When the two are stacked, the convex column is embedded in the groove for combination, and is reinforced by the magnetic block 3. The structure is simple, easy to assemble and disassemble, no unlocking operation is required, and it is not easy to cause relative displacement to affect the electrical contact.

One end of the bracket 26 is pivotally connected to the bracket groove 27 so that the bracket 26 can be turned out from the bracket groove 27 or put into the bracket groove 27. At the same time, the length of the bracket groove 27 is slightly longer than the bracket 26 so that a gap 271 is left between the free end 261 of the bracket 26 and the bracket groove 27. When the bracket 26 is put into the bracket groove 27, the two sides of the bracket 26 are interference fit with the groove wall of the bracket groove 27 to prevent the bracket 26 from turning out. When in use, the free end 261 of the bracket 26 is pried through the gap 271 so that the bracket 26 is forced to turn out of the bracket groove 27. At this time, with the support of the bracket 26, the second main body 2 can be tilted to be used as a mobile phone holder.

[0039] To facilitate users to understand the battery power in real time, the second body 2 is also provided with a display screen 28 and a trigger button 29. The display screen 28 is connected to the second circuit board 23 to display the power information of the storage battery 24, and the trigger button 29 is connected to the second circuit board 23 to trigger the display screen 28 to turn on and off.

[0040] In addition, according to the different demands for power capacity in various usage scenarios, multiple second bodies 2 with different capacities can be designed for users to choose from, forming a complete set of products including chargers and mobile power supplies of multiple specifications. For example, a second body with a capacity of less than 20,000 mAh is used to cope with occasions such as airplanes and high-speed trains, while a second body with a capacity of more than 20,000 mAh is used to cope with occasions with higher endurance requirements such as outdoor activities, which to a certain extent breaks the limitations of power capacity.
