Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a wireless charging bank that can be placed stably. Background Technology

[0002] A portable power bank with wireless charging capability is equipped with a wireless charging transmitter, which allows devices that support wireless charging to generate electricity and charge through electromagnetic signals from the transmitter. This frees users from the constraints of cables and makes it convenient to charge devices such as mobile phones and headphones. When electronic devices are wirelessly charged via power bank, they are usually magnetically attached to the power bank for easier access to information and videos, and to ensure a more comfortable viewing angle. However, due to the varying sizes and weights of electronic devices, if the magnetic force is insufficient, the device can easily slip off under slight external force. Furthermore, heavier electronic devices may not be able to maintain a stable and effective charging connection with the power bank. Utility Model Content

[0005] As a further preferred embodiment of this utility model, a power button is fixedly installed on one side of the main control board, and the power button extends through a slot on one side of the front cover to the outside of the front cover, and the power button is electrically connected to the main control board.

[0006] As a further preferred embodiment of this utility model, a magnetic sticker is fixedly installed on the rear side of the bottom shell.

[0007] As a further preferred embodiment of this utility model, the support cover plate further includes a first folding part, one end of which is movably connected to the bottom shell located below the main control board, and the other end of which is movably connected to a second folding part. The end of the second folding part away from the first folding part is movably connected to a third folding part. The first folding part, the second folding part, and the third folding part are all artificial leather-wrapped plastic plate structures, and metal plates are fixedly installed on the side of the first folding part, the second folding part, and the third folding part relative to the bottom shell. By setting the support cover plate into three parts, the first folding part, the second folding part, and the third folding part, a triangular support structure can be formed when supporting the bottom shell.

[0008] As a further preferred embodiment of this utility model, the main control board has two first mounting slots, and the fixed seat has a second mounting slot on one side. The two sets of first and second mounting slots are symmetrically provided in the main control board to provide operating space for the installation of the limit buckle and the connecting piece. Two L-shaped fixing shafts are fixedly installed on the side of the main control board opposite to the face shell, and the two L-shaped fixing shafts are respectively close to one of the first mounting slots. The setting of the L-shaped fixing shafts can provide a base point for the axial movement of the connecting piece.

[0009] As a further preferred embodiment of this utility model, the fixing seat has a shaft hole, and a connecting seat is fixedly installed on one side of the fixing seat near the shaft hole. A limit buckle is fixedly installed on the side of the connecting seat away from the fixing seat, and the longitudinal section of the limit buckle is semi-circular.

[0010] As a further preferred embodiment of this utility model, a fixing ring is fixedly installed on the outer side of the connecting rod near the push-pull buckle. The connecting rod is inserted and installed in the limiting buckle and the shaft hole. A compression spring is also fitted on the outer side of the connecting rod.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-9 As shown, this utility model provides a stable wireless charging bank, including a bottom shell 1, a front shell 2 fixedly installed on the front side of the bottom shell 1, a main control power module 3 fixedly installed on the front side of the bottom shell 1, and the main control power module 3 is also located inside the front shell 2. A wireless charging module 4 is fixedly installed on the front side of the main control power module 3. A wireless earphone charging case module 5 is provided on the rear side of the bottom shell 1. A support cover plate 6 is also movably installed on the rear side of the bottom shell 1. A main control board 7 is fixedly installed on the bottom shell 1 below the main control power module 3. The main control power module 3, the wireless charging module 4 and the wireless earphone charging case module 5 are electrically connected to the main control board 7 through ribbon cables. A linkage mechanism 8 is provided on the bottom shell 1 below the wireless earphone charging case module 5. The linkage mechanism 8 includes a fixed seat 9 fixedly installed on the front side of the bottom shell 1. A connecting rod 10 is movably installed in the fixed seat 9. A push-pull buckle 11 is fixedly installed on one side of the connecting rod 10. A storage slot 12 is opened in the front shell 2. A support plate 13 is movably installed in the storage slot 12.

[0017] like Figures 2-3 As shown, a power button 14 is fixedly installed on one side of the main control board 7. The power button 14 extends through a slot on one side of the front cover 2 to the outside of the front cover 2 and is electrically connected to the main control board 7. A magnet 15 is fixedly installed on the rear side of the bottom cover 1. The support cover 6 also includes a first folding part 16. One end of the first folding part 16 is movably connected to the bottom cover 1 located below the main control board 7. The other end of the first folding part 16 is movably connected to a second folding part 17. The end of the second folding part 17 away from the first folding part 16 is movably connected to a third folding part 18. The first folding part 16, the second folding part 17 and the third folding part 18 are all artificial leather with plastic plates inside. Metal plates are fixedly installed on the side of the first folding part 16, the second folding part 17 and the third folding part 18 opposite to the bottom cover 1. By setting the support cover 6 into three parts, the first folding part 16, the second folding part 17 and the third folding part 18, a triangular support structure can be formed when supporting the bottom cover 1.

[0018] like Figures 4-6 As shown, the main control board 7 has two first mounting slots 19, and the fixed base 9 has a second mounting slot 20 on one side. The two sets of first mounting slots 19 and second mounting slots 20 are symmetrically opened in the main control board 7 to provide operating space for the installation of the limit buckle 23 and the connecting piece 26. Two L-shaped fixing shafts 28 are fixedly installed on the side of the main control board 7 opposite to the face shell 2, and the two L-shaped fixing shafts 28 are respectively close to one of the first mounting slots 19. The setting of the L-shaped fixing shafts 28 can provide a base point for the axial movement of the connecting piece 26.

[0019] like Figures 4-9As shown, a shaft hole 21 is provided in the fixed base 9. A connecting base 22 is also fixedly installed on one side of the fixed base 9 near the shaft hole 21. A limit buckle 23 is fixedly installed on the side of the connecting base 22 away from the fixed base 9. The longitudinal section of the limit buckle 23 is semi-circular. A fixing ring 24 is fixedly installed on the outside of the connecting rod 10 near the push-pull buckle 11. The connecting rod 10 is inserted into the limit buckle 23 and the shaft hole 21. A compression spring 25 is also fitted on the outside of the connecting rod 10. One side of the compression spring 25 abuts against the push-pull buckle 11, and the other side abuts against the fixing ring 24. After the connecting rod 10 is inserted into the limit buckle 23 and the shaft hole 21, the force of the fixing ring 24 and the compression spring 25 can provide a rotatable connection. The plate 26 provides the power. Two connecting plates 26 are fixedly installed on one side of the support plate 13. Guide shafts 27 are fixedly installed on the opposite sides of the two connecting plates 26. The connecting plates 26 are rotatably mounted on one of the L-shaped fixed shafts 28. The guide shafts 27 are inserted into one of the push-pull buckles 11. When the support cover plate 6 is folded into a triangular support structure, the connecting rod 10 can be automatically pushed towards the support cover plate 6 by the force of the compression spring 25 and the fixing ring 24. This causes the push-pull buckle 11 to pull the guide shaft 27, so that the connecting plate 26 rotates around the L-shaped fixed shaft 28 and automatically opens the support plate 13. The slope at the bottom of the storage groove 12 limits the unfolding angle of the support plate 13.

[0020] It should be noted that this utility model is a wireless charging bank with stable placement. When the device is used at an angle, the first fold 16, the second fold 17, and the third fold 18 of the supporting cover 6 are folded to form a triangular support structure, and one side of the third fold 18 abuts against the rear side of the bottom shell 1. At the same time, the third fold 18 is displaced and limited by the slot on the rear side of the bottom shell 1, thereby completing the angled support of the bottom shell 1 and the top shell 2. When the first fold 16, the second fold 17, and the third fold 18 are unfolded and separated from the rear side of the bottom shell 1, the first fold 16 no longer limits one end of the two connecting rods 10. Therefore, the fixing ring 24 on the outer side of the connecting rod 10 automatically displaces under the action of the compression spring 25, thereby allowing the connecting rod 10 to be in the shaft hole The push-pull buckle 11 moves within the 21 and pulls the guide shaft 27 connected to the support plate 13. After the guide shaft 27 is pulled, the connecting piece 26 rotates around the L-shaped fixed shaft 28, and the guide shaft 27 slides within the push-pull buckle 11. This causes the connecting piece 26 to automatically open the support plate 13 from the storage slot 12 of the face shell 2. The opening angle is limited by the bottom slope of the storage slot 12 to support the bottom of the charging device and prevent it from slipping. Subsequently, the electronic device can be magnetically attached or directly placed on the face shell 2 and the support plate 13. The wireless charging module 4 converts electrical energy into electromagnetic signals through the principle of electromagnetic induction. When the wireless charging-enabled device is close to the face shell 2, the coil inside the device receives the electromagnetic signals and converts them into electrical energy to achieve wireless charging. When the bottom shell 1 and the top shell 2 are laid flat for use or storage, the first folding part 16, the second folding part 17, and the third folding part 18 can be adjusted to a flat state, and the first folding part 16, the second folding part 17, and the third folding part 18 are fixed to the side of the magnet 15 by adsorption of a metal sheet on one side. At the same time, the first folding part 16 presses the two connecting rods 10 to one side respectively, so that the two connecting rods 10 move in the corresponding shaft holes 21 respectively, and compress the corresponding compression springs 25 towards the limiting buckle 23 through the outer fixing ring 24. Then, the connecting rods 10 also push the guide shaft 27 through the push-pull buckle 11. The guide shaft 27 also slides in the push-pull buckle 11, so that the push-pull buckle 11 moves horizontally and the guide shaft 27 moves longitudinally in the push-pull buckle 11, so that the connecting piece 26 rotates around the L-shaped fixing shaft 28 as the axis, and then rotates the support plate 13 into the storage slot 12, so that the support plate 13 is automatically stored when the first folding part 16 is stored.
