When discharging and outputting, the MCU controls the power distribution of the transmitting coil through the output control circuit. The wireless charging technology of the power bank is an existing technology, and the circuit can refer to the existing publicly available circuit technology. In actual production, auxiliary components such as a power switch, a power display screen, and LED lighting beads can also be set.

[0057] In a further design, the clamping member 202 is an L-shaped plate-like clamping member, and the clamping member 202 is arranged in the clamping opening 101 for clamping the device to be charged. In addition, a sliding opening 103 is provided at the bottom of the power bank shell 10, and the pushing seat 110 is arranged in the sliding opening 103. In addition, in order to facilitate the pushing to rotate outward and pop out, a spherical head 1101 is fixedly connected to the bottom of the pushing seat 110, and the side wall of the sliding opening 103 is set as an arc edge 104.

[0058] In a further design, the inner wall of the clamping opening 101 is fixedly connected to a sliding seat 20, a slider 201 is slidably connected inside the sliding seat 20, and the clamping member 202 is rotatably connected to the slider 201. In this embodiment, four clamping openings 101 are set on the top of the power bank housing 10, and the clamping member 202 can be stored in the clamping opening 101.

[0059] Among them, a second guide rod 40 is fixedly connected inside the power bank shell 10, and a hinge seat 401 is slidably connected to the outside of the second guide rod 40. A connecting rod 30 is hinged to the outside of the hinge seat 401, and one end of the connecting rod 30 is hinged to the clamping member 202. The connecting rod 30 is used to push the clamping member 202 to move.

[0060] In addition, the outside of the slider 201 is also fixedly connected to a synchronization plate 204, and the outside of the synchronization plate 204 is fixedly connected to a limit plate 203, and the limit plate 203 is used to limit the rotation angle of the clamping member 202. A first limit column 207 is slidably connected through the synchronization plate 204, and an arc-shaped opening 2072 is provided on the outside of the first limit column 207. The end of the first limit column 207 can be set to a spherical shape.

[0061] In a further design, the outside of the first limiting column 207 is also fixedly connected to a first guide rod 2075, and the first guide rod 2075 penetrates and is slidably connected in the synchronous plate 204. The outside of the first limiting column 207 is sleeved with a first spring 2071, and the two ends of the first spring 2071 are respectively fixedly connected to the synchronous plate 204 and the first limiting column 207. The first spring 2071 plays a role in elastically pulling the first limiting column 207. A resistance plate 2073 is fixedly connected to the outside of the sliding seat 20, and one end of the resistance plate 2073 is fixedly connected to an arrow 2074, and the arrow 2074 corresponds to the arc-shaped opening 2072. When the arrow 2074 is plugged into the arc-shaped opening 2072, the first limiting column 207 will retract into the synchronous plate 204.

[0062] In order to allow the clamping member 202 to maintain a rotating motion when the connecting rod 30 pulls the clamping member 202, a groove 206 is further provided on the outside of the sliding seat 20, and a pin shaft 501 is rotatably connected in the groove 206. The outside of the pin shaft 501 is fixedly connected with an adjusting rod 50, and a torsion spring 503 is sleeved on the outside of the pin shaft 501. One end of the adjusting rod 50 is rotatably connected with a resistance wheel 502. Under the torsion of the torsion spring 503, the adjusting rod 50 drives the resistance wheel 502 to resist the outside of the protrusion 205.

[0063] Among them, the outside of the slider 201 is fixedly connected with a protrusion 205, one end of the protrusion 205 is an arc structure, the outside of the protrusion 205 is also fixedly connected with a protrusion 2051, and the groove 206 is fixedly connected with a second limit column 504, the second limit column 504 is used to limit the rotation and pop-up angle of the adjustment rod 50, and the second limit column 504 is in contact with the outside of the adjustment rod 50.

[0064] In addition, a second spring 208 is connected between the slider 201 and the sliding seat 20 , and a third spring 402 is connected between two adjacent hinge seats 401 .

[0065] The above technical solution is explained as follows: after the hinge seat 401 slides toward each other, the connecting rod 30 will pull the clamping member 202 to rotate (because at this time the abutting wheel 502 abuts against the outside of the protrusion 205, forming a resistance, so that the clamping member 202 first maintains the rotation action), and one end of the clamping member 202 rotates and extends to the outside of the clamping port 101, so that the clamping member 202 will be located on the side of the device to be charged. After the clamping member 202 rotates 90 degrees, the other end of the clamping member 202 will abut against the limit The outside of the plate 203 prevents the clamping member 202 from continuously rotating. At this time, as the hinge seat 401 slides toward each other, the connecting rod 30 pulls the slider 201 to slide through the clamping member 202, and the slider 201 compresses the second spring 208. The slider 201 resists the interference wheel 502 through the protrusion 205 and the protrusion 2051. Under the resistance of the protrusion 205, the interference wheel 502 rotates downward through the adjusting rod 50, and the adjusting rod 50 rotates toward the bottom of the groove 206 through the pin shaft 501.

[0066] The synchronization component is disposed in the power bank housing 10 and connected to the pushing seat 110 , and when the pushing seat 110 moves, the clamping member 202 is flipped.

[0067] Specifically, the synchronization component includes two groups of sliding plates 60 slidably arranged in the power bank housing 10 and a movable frame 70 slidably arranged outside the sliding plates 60. The two ends of the two groups of sliding plates 60 are respectively fixedly connected to two hinge seats 401, so that when the sliding plates 60 slide, they can drive the four clamping members 202 to work synchronously.

[0068] The outside of the sliding plate 60 is fixedly connected with an inclined plate 601 , and an inclined groove 602 is provided inside the inclined plate 601 , both of which are used to cooperate with the two sliding plates 60 to slide toward or away from each other.

[0069] Among them, the moving frame 70 is rotatably connected with the first roller 701 and the second roller 705, the second roller 705 is located in the inclined groove 602, the first roller 701 corresponds to the side of the inclined plate 601, and in the initial state, the first roller 701 maintains a distance of 0.1-0.5 cm from the side of the inclined edge, and the second roller 705 conflicts with the inclined edge of the inclined groove 602.

[0070] Among them, a guide rail 703 is fixedly connected inside the power bank shell 10, a fixing rod 80 is fixedly connected inside the power bank shell 10, a plurality of positioning grooves 801 are provided on the outside of the fixing rod 80, the positioning groove 801 is an isosceles triangle structure, an inner recessed groove 708 is provided in the movable frame 70, the fixing rod 80 is located in the inner recessed groove 708, an installation groove 707 is provided on the outside of the movable frame 70, a positioning block 90 is slidably connected in the installation groove 707, one end of the positioning block 90 is a pointed head, which is used to be plugged into and abutted against the positioning groove 801, and a fourth spring 901 is connected between the positioning block 90 and the installation groove 707.

[0071] In a further design, a notch 902 is provided on the top of the positioning block 90, the external fixed connection of the movable frame 70 is provided with two fixed bars 100, the external fixed connection of the fixed bar 100 is provided with a U-shaped plate 1001, a sliding block 1002 is slidably connected between the two fixed bars 100, a fifth spring 1003 is connected between the sliding block 1002 and the U-shaped plate 1001, the bottom of the sliding block 1002 is fixedly connected with a connecting rod 1005, the bottom of the connecting rod 1005 is fixedly connected with a third limiting column 1004, the external rotation connection of the sliding block 1002 is provided with a rotating rod 1102, and the rotating rod 1102 is fixedly connected to the pushing seat 110.

[0072] The above technical solution is explained as follows: the push seat 110 is rotated 90 degrees, and the push seat 110 is rotated through the rotating rod 1102, and the push seat 110 drives the spherical head 1101 to contact the arc edge 104, so that the sliding seat 20 slides outward until the spherical head 1101 completely contacts the outside of the bottom shell 102. After the push seat 110 slides outward, it drives the sliding block 1002 to slide outward, and the sliding block 1002 compresses the fifth spring 1003. At the same time, the connecting rod 1005 drives the third limiting column 1004 to no longer be located in the recess 902, so that the positioning block 90 can slide, and the push seat 110 can also be operated to move;

[0073] Then rotate the push seat 110 to rotate it ninety degrees. At this time, the spherical head 1101 corresponds to the sliding mouth 103. Under the elastic force of the fifth spring 1003, the sliding block 1002 will slide toward the direction of the fixed rod 80. At this time, the third limiting column 1004 will also be in contact with the recess 902, so that the positioning block 90 cannot slide backward, thereby locking the position of the positioning block 90.

[0074] In a further design, a first slide groove 704 is provided in the guide rail 703, and the edge of the first roller 701 extends into the first slide groove 704. The outside of the first roller 701 is coaxially fixedly connected with a gear 702, and a tooth groove 706 is provided on the outside of the guide rail 703. The tooth groove 706 meshes with the gear 702. Through the arrangement of the gear 702 and the tooth groove 706, when the movable frame 70 moves, the gear 702 can drive the first roller 701 to rotate, so that the first roller 701 can keep rotating to resist the inclined plate 601. In order to facilitate sliding, a slide bar 120 is fixedly connected to the bottom of the movable frame 70, and a second slide groove 1201 is provided inside the power bank shell 10. The slide bar 120 is slidably connected to the second slide groove 1201.

[0075] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0076] First, place the device to be charged (such as a mobile phone or tablet) on the top of the power bank housing 10, and then rotate the push seat 110 90 degrees. The push seat 110 can be rotated through the rotating rod 1102, and the push seat 110 will drive the spherical head 1101 to contact the arc edge 104, allowing the sliding seat 20 to slide outward until the spherical head 1101 completely contacts the outside of the bottom shell 102. After the push seat 110 slides outward, it will drive the sliding block 1002 to slide outward, and the sliding block 1002 compresses the fifth spring 1003. At the same time, the connecting rod 1005 drives the third limit column 1004 to no longer be located in the recess 902;

[0077] Secondly, the push seat 110 is operated to move linearly, and the push seat 110 drives the moving frame 70 to move linearly, and the moving frame 70 drives the first roller 701 and the second roller 705 to move linearly to attach Fig.12 Taking the direction shown in the figure as an example, the movable frame 70 moves downward, the second roller 705 does not contact the inclined edge of the inclined groove 602, and at the same time, the first roller 701 contacts the side of the inclined plate 601, and the two sliding plates 60 slide toward each other, and the sliding plates 60 drive the hinge seat 401 to move toward each other. Figure 7 As shown in the figure, after the hinge seat 401 slides toward each other, the connecting rod 30 will pull the clamping member 202 to rotate, so that one end of the clamping member 202 rotates and extends to the outside of the clamping port 101, so that the clamping member 202 will be located on the side of the device to be charged. After the clamping member 202 rotates ninety degrees, the other end of the clamping member 202 will contact the outside of the limit plate 203, so that the clamping member 202 will not continue to rotate. At this time, as the hinge seat 401 slides toward each other, the connecting rod 30 will pull the slider 201 to slide through the clamping member 202, and the slider 201 will compress the second spring 208. The slider 201 will contact the contact wheel 502 through the protrusion 205 and the protrusion 2051. Under the contact of the protrusion 205, the contact wheel 502 will rotate downward through the adjusting rod 50, and the adjusting rod 50 will rotate toward the bottom of the groove 206 through the pin 501;

[0078] As the hinge seat 401 continues to slide toward each other, the slider 201 will abut against the bottom of the abutment wheel 502. After the slider 201 moves, it will drive the synchronous plate 204 to move synchronously. After the synchronous plate 204 moves, the arrow 2074 is no longer plugged into the arc-shaped opening 2072. Therefore, under the elastic force of the first spring 2071, the limit column extends out of the synchronous plate 204 for a certain distance and abuts against the bottom of the clamping member 202. Figure 7 The state of the first limiting column 207 is the state at this time;

[0079] Continuously operating the push seat 110 to move can drive the clamping member 202 to clamp and fix the two ends of the charging device. Under the elastic force of the fourth spring 901, the positioning block 90 will also continuously engage and contact with the positioning groove 801. When the clamping member 202 completely clamps the device to be charged, the push seat 110 is rotated again to rotate it ninety degrees. At this time, the spherical head 1101 corresponds to the sliding mouth 103. Under the elastic force of the fifth spring 1003, the sliding block 1002 will slide toward the direction of the fixed rod 80. At this time, the third limit column 1004 will also contact with the recess 902, preventing the positioning block 90 from sliding backwards, thereby locking the position of the positioning block 90. ​​Subsequently, wireless charging can be performed through the transmitting coil.

[0080] When the device needs to be removed after charging, the above principle is reversed. First, rotate the push seat 110 90 degrees again to allow the third limiting column 1004 to disengage from the recess 902, and push the push seat 110 upward to move, so that the second abutment wheel 502 will abut against the inclined groove 602, so that the two sliding plates 60 slide back to back, and the hinge seat 401 slides back to back. The connecting rod 30 pushes the clamping member 202 to move. Under the limitation of the limiting plate 203 and the first limiting column 207 on the clamping member 202, the clamping member 202 cannot rotate, and the clamping member 202 will push the slider 201 to slide in the sliding seat 20, so that the elastic force of the second spring 208 can be released. When the slider 201 slides to the initial position, the arrow 2074 will abut against the arc-shaped opening 2072. See attached Figure 8 As shown in FIG. 2 , after the arrow 2074 contacts the arc-shaped opening 2072, the limit rod will be retracted into the synchronization plate 204. At this time, as the connecting rod 30 continues to push, the arrow 2074 will contact the arc-shaped opening 2072, blocking the continuous sliding of the slider 201, thereby allowing the clamping member 202 to rotate toward the clamping opening 101, so that the clamping member 202 is stored in the clamping opening 101, and the adjustment rod 50 will also pop outward under the torsion of the torsion spring 503. , let the abutment wheel 502 abut against the outside of the protrusion 205 again, and finally rotate the push seat 110 to rotate it ninety degrees. At this time, the spherical head 1101 corresponds to the sliding mouth 103, and under the elastic force of the fifth spring 1003, the sliding block 1002 will slide toward the direction of the fixed rod 80. At this time, the third limiting column 1004 will also abut against the recess 902, so that the positioning block 90 cannot slide backward, thereby locking the position of the positioning block 90.
