Embodiment 1

[0016] like Figure 1-2 As shown, the freely increasing capacity mobile power supply includes a main body 1 and an auxiliary body 2. A battery box is arranged inside the main body 1 and the auxiliary body 2, and a contact piece 5 is fixed at both ends of the battery box, and each contact piece 5 is equipped with a There is a first contact 51, the first contact 51 at one end of the battery box is used to contact the positive pole of the battery 7, the first contact 51 at the other end of the battery box is used to contact the negative pole of the battery 7, the main body 1 and the auxiliary body 2 are electrically connected via contact 5. Inside the main body 1, a circuit board 13 is installed on one side of the battery box 14, a first magnet 3 is fixed on the side wall connecting the main body 1 and the auxiliary body 2, and the side of the main body 1 away from the auxiliary body 2 is provided with a USB output interface 11 and The charging input interface 12, the USB output...

Embodiment 2

[0019] The present embodiment also includes a main body 1 and an auxiliary body 2. A battery case is arranged inside the main body 1 and the auxiliary body 2, and a contact piece 5 is fixed on both ends of the battery case. The contacting first contact 51 , the main body 1 and the auxiliary body 2 are electrically connected through the contact piece 5 . Inside the main body 1, a circuit board 13 is installed on one side of the battery box 14, a first magnet 3 is fixed on the side wall connecting the main body 1 and the auxiliary body 2, and the side of the main body 1 away from the auxiliary body 2 is provided with a USB output interface 11 and The charging input interface 12, the USB output interface 11, the charging input interface 12 and the contact piece 5 in the main body 1 are all electrically connected to the circuit board 13, and the side wall that the auxiliary body 2 is connected to the main body 1 is fixed with a magnet that attracts the first magnet 3. The second m...

Abstract

The invention relates to a freely capacity increasing mobile power supply. The freely capacity increasing mobile power supply comprises a main body and an auxiliary body, wherein battery compartments are arranged in both the main body and the auxiliary body, contact plates are fixedly arranged at the two ends of each battery compartment, the main body is electrically connected with the auxiliary body through the contact plates, a first magnet is fixedly arranged on the side wall, connected with the auxiliary body, of the main body, a second magnet which is attracted with the first magnet is fixedly arranged on the side wall, connected with the main body, of the auxiliary body, and a first magnet is fixedly arranged on the side wall, which is far from the main body, of the auxiliary body. The freely capacity increasing mobile power supply has the benefits that as batteries in the main body and the auxiliary body are connected in parallel, the number of the auxiliary body can be increased without limitation, the capacity of the batteries in the main body can be set smaller, and the weight of the power supply is reduced; after the power of the batteries in the main body is used up, one or more of auxiliary bodies can be connected selectively according to actual conditions, and the unused auxiliary body does not need to be carried along, so that the use is very convenient.

Description

technical field [0001] The invention relates to a freely expanding mobile power supply, which belongs to the technical field of electronic products. Background technique [0002] With the popularization and use of large-screen and multi-core mobile phones, the battery life of mobile phones is getting worse and worse, so mobile power supplies that can be carried around to charge mobile phones are becoming more and more widely used. But current mobile power supply all has following shortcoming: its lithium battery is fixed in the inside of mobile power supply, can not be disassembled, because current mobile power supply capacity is bigger, and weight is heavier, it is quite inconvenient to need to carry whole power supply every time going out to use. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a portable and easy-to-use mobile power supply with free capacity expansion. [0004] For real...
