Description

Technical Field

[0001] The invention relates to the field of mobile power supplies, and in particular to an adsorption-type wireless charging mobile power supply. Background Art

[0002] Wireless charging technology originates from wireless power transmission technology. When current passes through the coil, a magnetic field is generated. The generated magnetic field forms a voltage, and with voltage, current is generated, and with current, charging can be achieved.

[0003] With the development of technology, wireless charging technology is now also applied to the field of mobile power. Users only need to place the device on the designated area on the surface of the mobile power, and the mobile power can wirelessly charge the device.

[0004] Since the device and the transmitting coil need to be kept close to each other for stable charging, and usually, the transmitting coil part is placed flat on the table, and the device is placed flat on it for charging. For devices such as mobile phones, they need to be moved frequently. Once the device and the transmitting coil are moved, charging may stop (or affect the charging speed and efficiency). Therefore, a suction cup wireless charging mobile power bank 201721584654.9 appeared on the market, which can stably absorb the mobile phone and charge it wirelessly. However, this traditional silicone suction cup is usually composed of multiple small suction cups, and it is difficult to coordinate with the mobile power bank itself in terms of structure and appearance design, and the overall consistency is poor; and the adsorption stability of this small suction cup is not good, and it is troublesome to adsorb or remove it. Summary of the invention

[0005] In view of the above problems, the present invention aims to provide an adsorption-type wireless charging mobile power supply with stable adsorption, easy removal and good arrangement consistency.

[0006] To achieve the technical purpose, the solution of the present invention is: an adsorption type wireless charging mobile power supply, comprising an upper shell, a lower shell, an elastic movable part, and a PCB board, wherein a button is arranged on the upper part of the upper shell, a battery is installed between the upper shell and the lower shell, and the PCB board is installed between the upper shell and the lower shell;

[0007] A transmitting coil for wireless charging is arranged below the battery, and a magnetic isolation sheet is arranged between the battery and the transmitting coil;

[0008] The middle part of the lower shell is an open hole structure, the elastic movable part is installed in the middle part of the lower shell, and a raised sealing ring is also provided on the lower surface of the lower shell. The sealing ring and the middle part of the lower shell form a cavity. When the button is pressed, the battery moves downward to push the middle part of the elastic movable part to open downward.

[0009] Preferably, a first gasket for protecting the magnetic isolation plate and the transmitting coil is provided between the battery and the elastic movable part, and the first gasket is located on both sides of the magnetic isolation plate and the transmitting coil.

[0010] Preferably, a second gasket for protecting the battery is provided between the battery and the button.

[0011] Preferably, the elastic movable part and the sealing ring are an integrally formed structure.

[0012] Preferably, a non-metallic hard sheet is also adhered to the lower surface of the elastic movable part.

[0013] Preferably, an input port and a switch are further provided on one side of the upper shell, and the switch, the input port, the battery and the transmitting coil are electrically connected to the PCB board respectively.

[0014] Preferably, the elastic movable part is in a concave-shaped structure, and a T-shaped connecting portion is further provided on the elastic movable part, and the connecting portion is nested and connected with the first gasket.

Compared with traditional suction cups, the adsorption force is greater and the stability is better. The adsorption can also be released with one button, making it more convenient to remove. At the same time, the distance between the sealing ring of the present application and the lower shell body is shorter, which is much smaller than that of traditional suction cups. The suction cup structure formed by the sealing ring itself has certain hidden characteristics, which makes the entire product have a high sense of coordination and integrity, enhances the beauty of the product, and makes it easier for consumers to accept it.

[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-9 As shown, the specific embodiment of the present invention is an adsorption-type wireless charging mobile power supply, comprising an upper shell 1, a lower shell 2, an elastic movable part 3, and a PCB board 15. A button 4 is arranged on the upper part of the upper shell 1, a battery 5 is installed between the upper shell 1 and the lower shell 2, and the PCB board 15 is installed between the upper shell 1 and the lower shell 2;

[0030] A transmitting coil 7 for wireless charging is provided below the battery 5, and a magnetic isolation sheet 8 is provided between the battery 5 and the transmitting coil 7;

[0031] The middle part of the lower shell 2 is an open hole structure, which can be a circular or elliptical or other shaped large hole structure. The elastic movable part 3 is nested or rubber-wrapped or bonded or ultrasonically welded and installed in the middle part of the lower shell 2. The lower surface of the lower shell 2 is also provided with a raised sealing ring 9, and the sealing ring 9 and the middle part of the lower shell 2 form a cavity (such as Figure 2 , 7 ), after pressing the button, the battery moves downward to push the middle part of the elastic movable part downward, squeezing out some air in the middle cavity of the sealing ring, and placing the device to be charged on the sealing ring. After releasing the button, the elastic movable part contracts upward to form negative pressure (due to the exhaust of air, the air density and air pressure in the sealed space decrease, and the external atmospheric pressure is significantly higher than the air pressure in the sealed space), which adsorbs the device to be charged.

[0032] In order to protect the magnetic isolation sheet and the transmitting coil from damage due to extrusion (especially the magnetic isolation sheet is very brittle and easily damaged by force), a first gasket 10 for protecting the magnetic isolation sheet and the transmitting coil is provided between the battery 5 and the elastic movable part 3, and the first gasket 10 is located on both sides of the magnetic isolation sheet 8 and the transmitting coil 7. The magnetic isolation sheet is very brittle and easily damaged when squeezed by external force. At the same time, the transmitting coil is also relatively thin and easily deformed after being squeezed. The first gasket can effectively transfer the force on the battery to the elastic movable part, avoiding the magnetic isolation sheet and the transmitting coil from being directly squeezed, protecting the magnetic isolation sheet and the transmitting coil and playing a role in evenly dispersing the pressure.

[0033] In order to protect the battery from being squeezed and damaged, a second gasket 11 is provided between the battery 5 and the 4 buttons to protect the battery. As the outer packaging material of the polymer battery is relatively thin, local squeezing can easily cause deformation or damage to the battery. Since the body of the polymer battery is flexible, concentrated force will cause deformation. After the deformation, the compressed part in the middle of the battery will have been squeezed and deformed when the product is pressed, which will seriously affect the use of the product and even make the product unusable. The use of the second gasket can greatly increase the contact area, reduce concentrated force, and effectively protect the battery from deformation or damage. At the same time, the battery is not easy to be squeezed and deformed by adding the second gasket. However, if there is no second gasket, the battery will be directly deformed, which will affect the expansion and contraction of the elastic movable part, and it is easy to transfer the pressure directly to the magnetic isolation sheet, causing the magnetic isolation sheet to be damaged.

[0034] In order to obtain better airtightness, the elastic movable part 3 and the sealing ring 9 are an integrally formed structure, and the elastic movable part, the sealing ring and the lower shell are an integrally rubber-coated structure. Traditionally, methods such as bonding and clamping are usually used to form an integral body with the lower shell, which has poor sealing performance and poor structural stability. The adhesive is prone to debonding after long-term use. In comparison, the integrally formed and integrally rubber-coated structures of the present application have better sealing performance and longer service life. In this way, the sealing ring, the elastic movable part and the lower shell form a complete closed cavity structure, and the air in the elastic movable part can be squeezed out to form a stable negative pressure, which can firmly adsorb the mobile phone.

[0035] In order to further enhance the integrity of the product while protecting the internal structure, a non-metallic hard sheet 12 is also attached to the lower surface of the elastic movable part 3. The non-metallic hard sheet is located on the lower surface of the elastic movable part, and can move downward with the elastic movable part when pressed. When the external force pushes upward from the bottom, the non-metallic hard sheet will be stuck on the surface of the lower shell and will not be squeezed inward. It effectively resists impact and protects the internal magnetic isolation sheet, battery and transmitting coil. The non-metallic hard sheet is to further enhance the integrity of the product, cover most of the rubber soft rubber material, so that from the outside, only the soft rubber gasket part of the product is made of soft rubber material, and the other parts are an organic whole; on the other hand, the product-related parameters will be printed on the hard sheet.

[0036] In order to facilitate the control circuit and charging, an input port and a switch 18 are also provided on one side of the upper shell 1. The switch 18, the input port, the battery 5 and the transmitting coil 7 are electrically connected to the PCB board 15 respectively.

[0037] In order to make the elastic movable part more stable, the elastic movable part 3 is in a concave shape, and a T-shaped connecting part 13 is also provided on the elastic movable part 3, and the connecting part 13 is nested and connected with the first gasket 10 (to fully ensure the connection stability between the first gasket and the elastic movable part). The first gasket is not easy to slide when it moves, and can be stably opened downward with the elastic movable part.

[0038] In order to facilitate charging the mobile power supply, the input port includes one or both of the magnetic input port 17 and the plug-in input port 14. Traditional mobile power supplies are a combination of socket input + socket output, which is not convenient when charging. The preferred embodiment of the present application adopts a structure of a combination of magnetic input + socket input, which is more flexible and convenient when charging the mobile power supply. Since this product is mainly for wireless charging, whether there is a socket output is only an alternative, not a must. The present application can also adopt a combination of magnetic input + socket output.

[0039] A magnetic conductive metal block 16 is also provided on one side of the magnetic input port 17, and the magnetic conductive metal block 16 is fixedly installed in the middle of the upper shell 1 and the lower shell 2 (in order to facilitate production and positioning, the magnetic conductive metal block is currently directly designed to be fixed on the circuit board by soldering). The magnetic input port 17 is adsorbed and connected with the magnetic conductive metal block 16, wherein the magnetic conductive metal block can be a metal block with ferromagnetic effect such as a magnet, an iron block or a nickel block, preferably a nickel block. When the magnetic charging line 19 is not connected ( Figure 8 ), the magnetic conductive metal block absorbs and shrinks the magnetic input port into the upper shell and the lower shell; when the magnetic charging line 19 is connected ( Fig. 9 ), the magnetic charging cable 19 has a stronger magnetic adsorption force than the internal magnetic conductive metal block, the magnetic charging cable 19 slightly adsorbs and extends the magnetic input port, and the charging cable and the magnetic charging connector are adsorbed and electrically connected. This design can effectively protect the magnetic input port and avoid damage when it falls.

[0040] For better resetting, a resetting spring 6 is further provided between the button 4 and the second gasket 11. After pressing the button, the button will only partially reset due to the weak elastic force of the elastic movable part, and the spring can better reset the button to the initial position.

[0041] When in use, as shown in Figure 2-4, after pressing the button, the button pushes the battery downward, and the battery pushes the middle of the elastic movable part downward to open through the first gasket (the first gasket can effectively disperse the force), and the elastic movable part squeezes out part of the air in the sealing ring, and the mobile phone 20 is placed on the sealing ring (the sealing ring, the elastic movable part, and the mobile phone form a sealed cavity, Figure 3 ), after releasing the button, the elastic movable part shrinks upward and resets to form negative pressure in the sealing ring (the pressure inside the cavity is lower than that outside, Figure 4 ), firmly adsorb the mobile phone 20; when the mobile phone 20 needs to be removed, press the button, the middle part of the elastic movable part opens downward, and the pressure in the sealing ring returns to normal, then the mobile phone can be easily removed.

[0042] The present application can be adsorbed on the mobile phone at any time to charge it, and can also be taken down anytime and anywhere, which can effectively ensure the stability of wireless charging. Compared with traditional suction cups, the adsorption force is greater and the stability is better. It can also be released by one button, which is more convenient to remove. At the same time, the sealing ring of the present application is protruding from the lower shell body at a shorter distance, which is much smaller than the traditional suction cup. The sealing ring structure of the present application that realizes the suction cup function has certain hidden characteristics, which makes the whole product have a high sense of coordination and integrity, enhances the beauty of the product, and makes it easier for consumers to accept it.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any slight modification, equivalent substitution and improvement made to the above embodiment based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
