[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a foldable magnetic power bank, including a housing 1. A connector 2 is rotatably connected to the middle of one side of the housing 1. A housing 3 is rotatably connected to the bottom of the connector 2. A connector 4 is rotatably connected to the middle of the other side of the housing 1. A housing 5 is rotatably connected to the top of the connector 4. The connector 2 and connector 4 have the same structure. Lithium batteries are fixedly installed inside the housings 1, 3, and 5. The three sets of lithium batteries are electrically connected in sequence by wires and connected to a power control circuit board. The length, width, and thickness of the housings 1, 3, and 5 are all the same. A baffle 10 is provided at the top of the housing 5, and the length and width of the baffle 10 are the same as those of the housing 5.

[0025] Among them, the top of the shell 2 3 is fixedly connected to a rubber base 7. The rubber base 7 is wavy and fully covers the top of the shell 2 3, so that the shell 3 5 can be fixed in the shell 2 3 at a suitable angle after unfolding.

[0026] The four corners of the interior of the first shell 1 are provided with slots, and magnetic plates 8 are fixedly connected inside each slot. The top of the second shell 3 and the bottom of the third shell 5 are provided with magnetic blocks 9 that attract the magnetic plates 8, so as to fix the first shell 1, the second shell 3 and the third shell 5 after folding, thereby reducing storage space.

[0027] Among them, the connector 2 includes a connecting block 201, and the sides of the connecting block 201 are provided with wire grooves; two sets of damping shafts 202 are connected to both sides of the connecting block 201, and the housing 1, housing 2 3 and housing 3 5 are all connected by the damping shafts 202, which makes it easy to flip the housing 1, housing 2 3 and housing 3 5 to the required position.

[0028] The housing 3 5 has mounting grooves on both sides near the connector 2 4. The mounting grooves are rotatably connected to mounting feet 6 through the connector 3. The top of the mounting feet 6 is fixedly connected to the baffle 10, which facilitates sunshade of the mobile phone when it is charged outdoors, making it easier to see the phone, and at the same time protects the adsorption sensing area 11.

[0029] The outer center of the shell 3 5 is provided with an adsorption sensing area 11, and the bottom of the adsorption sensing area 11 is provided with multiple sets of magnetic blocks and a set of charging induction coils, which facilitates wireless charging of mobile phones while keeping the mobile phones and power banks in close contact to prevent them from falling and affecting charging efficiency.

[0030] The housing 3 5 has multiple sets of power indicator lights 12 on one side, and a control switch 13 on the same side. The control switch 13 and the multiple sets of power indicator lights 12 are electrically connected to the power control circuit board. The power control circuit board is fixedly installed inside the housing 3 5 so that the remaining power in the power bank can be easily known during use, which is beneficial to use.

[0031] The working principle of this embodiment is as follows: First, the design of connector 1 (2) and connector 2 (4) allows the housing 1 (1), housing 2 (3), and housing 3 (5) to be rotatably connected to each other, and can then be folded and unfolded as needed. Next, magnetic plates 8 are fixedly connected to the four corners inside housing 1 (1), and magnetic blocks 9 are set at the top of housing 2 (3) and the bottom of housing 3 (5) to facilitate magnetic fixation after housing 1 (1), housing 2 (3), and housing 3 (5) are folded, preventing them from unfolding when not in use. When the power bank is in use, the baffle 10 at the top of housing 3 (5) is first unfolded through the mounting feet 6 to provide sun protection for the phone, making it easier to view. At the same time, when not in use, the baffle 10 is closed to protect the adsorption sensing area 11. Then, the phone is placed in the adsorption sensing area 11 for charging. Under the action of multiple sets of magnetic blocks on one side of the adsorption sensing area 11, the phone is prevented from falling during charging, thus affecting the charging efficiency.

[0032] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
