[0029] The principles and structures of the present application will be described in detail below in conjunction with the drawings and examples.

[0030] Embodiment

[0031] As Figure 1 , 2 , 3, a mobile power supply, comprising a shell 1, a battery 2 and a wireless power supply module arranged in the shell 1, the wireless power supply module comprising a charging control circuit board 3, so as to provide the battery 2 with wireless transmission of electrical energy to the wireless receiving coil of the mobile terminal device by using the wireless power supply coil 4, and the lower end of the front surface of the shell 1 corresponding to the wireless power supply coil 4 is provided with a blocking body protruding from the front surface; the back of the shell 1 is provided with a support plate 5, and the upper end of the support plate 5 is rotatably connected to the upper end of the back of the shell 1 through a hinge shaft 7, and rotating the support plate 5 makes the support plate 5 and the mobile power supply have a certain included angle, so that the support plate 5 and the mobile power supply form a "person" shaped bracket, so that the mobile power supply can be inclined and supported on the surface of a table or other articles, so as to realize the inclined support of the mobile phone 13, so that the mobile power supply can be used as a mobile phone 13 support, and the blocking body is used to support the bottom of the mobile phone 13, so as to facilitate the use of the mobile phone 13 while charging. As Figure 7 , 8As shown, the stop body is a strip-shaped body 8, which is rotatably connected to the housing 1 via a hinge 6. This allows the strip-shaped body 8 to rotate relative to the housing 1. The hinge 6 can be a spring-loaded, elastic hinge 6, so that the upper surface of the strip-shaped body 8 is in contact with the surface of the housing 1 in its natural state. In this embodiment, the back of the power bank has a groove 101, and the hinge 6 is located within the groove 101, allowing the support plate 5 to be rotatably housed within the groove 101.

[0032] like Figure 4 , 5 As shown in Figure 6, the strip-shaped body 8 has a strip-shaped cavity along its length, meaning the interior of the strip-shaped body 8 is hollow. A gear 10, capable of freely rotating around a positioning shaft 9, is located in the center of the strip-shaped cavity. Both ends of the positioning shaft 9 are fixedly connected to the strip-shaped body 8. The gear 10 is rotatably mounted on the positioning shaft 9. During rotation, the axis of rotation of the gear 10 corresponds vertically to the center of the wireless power supply coil 4. That is, the positioning shaft 9 and the center of the wireless power supply coil 4 are located on the same straight line perpendicular to the strip-shaped body 8. Two racks 11 are symmetrically meshed on both sides of the gear 10. The two racks 11 are respectively connected to two clamping blocks 12, thus causing the two sliders to synchronously move closer to or further away from the positioning shaft 9. The two clamping blocks 12 are equidistant from the positioning shaft 9, ensuring that regardless of how the clamping blocks 12 move, the positioning shaft 9 remains centered between the two clamping blocks 12. At the location, the strip body 8 is provided with a sliding groove 801 connecting the inside and outside of the strip cavity. The lower end of the clamping block 12 is connected to the rack 11, and the upper end of the clamping block 12 extends outward from the sliding groove 801. The clamping block 12 is an I-shaped block with notches on both sides in the middle. The notches in the middle of the clamping block 12 slide and engage with the edge of the sliding groove 801. The clamping block 12 and the end of the strip cavity are provided with a return spring 14. When the lower end of the mobile phone 13 is placed on the strip body 8, the return spring 14 causes the clamping block 12 to clamp the two sides of the lower end of the mobile phone 13. In this way, not only can the mobile phone 13 be fixed, but also because there are two clamping blocks 12 and the distance of the two clamping blocks 12 from the axis of symmetry is always equal, the center line of symmetry of the mobile phone 13 always corresponds to the center of the wireless power supply coil 4, so that the wireless receiving coil on the mobile phone 13 can also keep corresponding to the wireless power supply coil 4.

[0033] The upper end of the clamping block 12 is provided with a guide wheel 15 so that the lower end of the mobile phone 13 can be smoothly inserted between the two clamping blocks 12. In the natural state, the distance between the two clamping blocks 12 is less than the width of the mobile phone 13.

[0034] like Figure 7 , 8As shown, the housing 1 is provided with a slot 104 corresponding to the clamping block 12, and the strip-shaped body 8 is rotated around the shaft hinge 6 so that the clamping block 12 is inserted into the slot 104.

[0035] The front surface of the housing 1 includes a protrusion 102 corresponding to the wireless power supply coil 4 and a lower recess 103 connecting the shaft hinge 6, that is, the housing 1 has a stepped front surface, and when the clamping block 12 is inserted into the slot 104, the strip-shaped body 8 is lower than the surface of the protrusion 102, so as to be accommodated, so that the surface of the mobile power supply is regular.

[0036] As shown, the wireless power supply coil 4 is arranged on a moving plate 16, and the moving plate 16 is controlled to move in a plane by a translation mechanism. The translation mechanism includes a screw rod 17 in the up-down direction, and the moving plate 16 is provided with a screw sleeve 18 matched with the screw rod 17, and the screw rod 17 is controlled to rotate by a motor 19, so that the motor 19 controls the rotation of the screw rod 17 to drive the movement of the wireless power supply coil 4, so that the wireless power supply coil 4 is aligned with the wireless receiving coil of the mobile phone 13, thereby facilitating efficient transmission of electric energy. Figure 9

[0037] Two guide rods 20 parallel to the screw rod 17 are further arranged on both sides of the screw rod 17, and the moving plate 16 is provided with a sliding sleeve 21 slidingly matched with the guide rod 20, and the two guide rods 20 provide a guiding effect for the movement of the wireless power supply coil 4.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.​
