DETAILED DESCRIPTION

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] See also Figures 1 to 10 In an embodiment of the present invention, a power bank with a mobile phone holder comprises a housing 1, a holder 6 and a charging interface 3, wherein a battery 16 and a circuit board 14 are arranged in the housing 1, wherein the battery 16 is connected to the circuit board 14, wherein the circuit board 14 is installed in the housing 1, and a charging plug 7 is arranged on the holder 6;

[0046] The circuit board 14 is provided with a USB interface 2, a charging interface 3, a power indicator light 4 and a switch button 5;

[0047] The shell 1 is provided with a USB hole 101, a charging interface hole 103 and a switch button hole 104, the USB interface 2 corresponds to the USB hole 101, the charging interface 3 corresponds to the charging interface hole 103, the switch button 5 corresponds to the switch button hole 104, and the switch button 5 is used to control the charging and discharging of the power bank and the power display.

[0048] Furthermore, a hollow shaft 601 is provided at the end of the bracket 6, and a damping ring A12 is sleeved on the hollow shaft 601. A hole A105 is provided on the shell 1. The damping ring A12 fits with the hole A105 on the shell 1. The damping ring A12 is intended to increase the resistance of the bracket 6 during rotation to prevent the bracket 6 from rotating freely during use.

[0049] Furthermore, a hole B603 is provided at the front end of the bracket 6, and a conductive ring A602 and a conductive ring B604 are provided in the hole B603, and the conductive ring A602 and the conductive ring B604 are coaxial with the hole B603;

[0050] The conductive ring A 602 and the conductive ring B 604 are connected to the wire 15 , and the wire 15 passes through the hollow shaft 601 and is connected to the circuit board 14 .

[0051] Furthermore, a damping ring B13 is sleeved on the tail end of the charging plug 7, and the damping ring B13 fits into the hole B603 on the bracket 6; the damping ring B13 is intended to increase the resistance of the charging plug 7 when it rotates relative to the bracket 6 to prevent the charging plug 7 from rotating freely during use.

[0052] Furthermore, a spring pin A701 and a spring pin B702 are provided at the tail end of the charging plug 7. The spring pin B702 is located at the center of the tail end of the charging plug 7. The spring pin A701 contacts the conductive ring A602 on the bracket 6, and the spring pin B702 contacts the conductive ring B604.

[0053] Furthermore, the rotation angle of the damping ring A12 in the hole A105 does not exceed 90 degrees, so that the rotation angle of the bracket 6 does not exceed 90 degrees, ensuring that the connection between the wire 15 and the circuit board 14 is completely stable and reliable during the rotation of the bracket 6.

[0054] In another embodiment of the present invention, the power bank with a mobile phone holder further includes a leg 8 and an end cover 9, and the housing 1 is provided with a receiving groove 102 for receiving the leg 8;

[0055] A ring 801 is provided at the end of the leg 8, and the ring 801 is fitted with the shaft 10. The shaft 10 is provided with a hole C1001. The end cover 9 is provided with a column B901 and a buckle 902. The hole C1001 is fitted with the column B901 and fixed by a screw 11. The end cover 9 is installed at the end of the shell 1 and fixed to the shell 1 by the buckle 902.

[0056] The working principle of the present invention is as follows: the battery 16 in the housing 1 is connected to the circuit board 14, and the circuit board 14 is connected to the conductive ring A602 and the conductive ring B604 through the wire 15. Since the rotation angle of the bracket 6 does not exceed 90 degrees (completely within the range of movement of the wire 15), the connection between the wire 15 and the circuit board 14 during the rotation of the bracket 6 is completely stable and reliable, so the wire 15 and the circuit board 14 will not be poorly contacted due to the rotation of the bracket 6. The conductive ring A602 and the conductive ring B604 are connected to the spring pin A701 and the spring pin B702. Since the conductive ring A602 is annular, the spring pin A701 is always in contact with the conductive ring A602 during the rotation of the charging plug 7, and the spring pin B702 is always in contact with the conductive ring B604. Therefore, no matter whether the bracket 6 rotates or the charging plug 7 rotates, the conduction between the circuit board 14 and the charging plug 7 will not be affected. After the mobile phone 17 is inserted into the charging plug 7, the resistance of the damping ring A12 can keep the bracket 6 at any angle, and the resistance of the damping ring B13 can keep the charging plug 7 at any angle.

[0057] The usage of the power bank with mobile phone holder is as follows:

[0058] 1. When the mobile phone 17 needs to be placed flat (e.g., put the mobile phone 17 in a pocket or a bag for charging), rotate the bracket 6 around the hole A105 and insert the mobile phone 17 into the charging plug 7; then fit the mobile phone 17 and the housing 1 together for use. Fig.11 shown.

[0059] 2. When the mobile phone 17 needs to be placed horizontally (e.g., watching a video while charging), rotate the bracket 6 around the hole A105 and insert the mobile phone 17 into the charging plug 7; then contact one side of the mobile phone 17 with the surface of the housing 1 and adjust the angle between the mobile phone 17 and the housing 1 to an angle suitable for viewing the mobile phone, such as Fig.12 shown.

[0060] 3. When the mobile phone 17 needs to be placed upright (e.g., for video calls), the bracket 6 is rotated around the hole A105, and the mobile phone 17 is inserted into the charging plug 7; then the mobile phone 17 is attached to the housing 1, the legs 8 are opened, and the legs 8 are adjusted to an angle suitable for viewing the mobile phone, such as Fig.13 shown.

[0061] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
