Description

Technical Field

[0001] This invention belongs to the field of portable power bank technology, specifically relating to a dustproof and waterproof portable power bank system and method with a magnetically attached interface hidden structure. Background Technology

[0002] As portable electronic devices, power banks have a certain level of dust and water resistance. For example, before assembling a power bank, detachable or fixed sealing rings are added to its interfaces, buttons, switches, and other parts. By compressing the sealing rings and deforming them to fit tightly against the gaps in the casing, a sealing effect is achieved.

[0003] In terms of dust and water resistance, existing power banks often have an independent battery compartment inside, which isolates the battery from the circuit board, thereby reducing the impact of moisture adhering to its surface on the core components.

[0004] In practical use, power banks are typically connected to an external charging cable, which exposes the cable and its associated output charging connector to the external environment, making them susceptible to dust and moisture. In severe cases, this can impair the normal conductivity of the charging cable, hindering the transfer of energy from the battery cells through the circuit, thus causing inconvenience to the user. Summary of the Invention

[0005] The purpose of this invention is to provide a dustproof and waterproof system and method for a mobile power bank with a magnetically attached interface hidden structure. It can insert two external output lines and their corresponding output charging connectors into the same cable box, and the holes on both sides of the cable box are sealed by sealing elements to keep dust and water out of the casing.

[0006] The specific technical solution adopted by this invention is as follows: A dustproof and waterproof power bank system with a magnetically attached interface concealed structure includes a housing, an energy storage component disposed inside the housing, and an output charging connector connected to the energy storage component. It also includes: A charging component is connected to the energy storage component. When the charging component is magnetically closed, it is used to separate the output charging connector from the external environment. When the charging component is open, it exposes the output charging connector to the external environment. magnet; A protective component, disposed outside the housing, is used to separate the magnet from the external environment.

[0007] As an optional solution, the charging component includes: Output line, used to connect the energy storage component to the output charging connector; The cable box is used to house the output charging connector. When the output wire is magnetically inserted into the cable box, it pulls the output charging connector into the cable box. When the output wire extends out of the cable box, it pulls the output charging connector out of the cable box.

[0008] As an optional solution, the junction box includes: The box body has a first through hole and a second through hole spaced apart on it; A first magnetic suction component, a second magnetic suction component, and a first sealing component are sequentially connected along the output line axis. When the first magnetic suction component and the second magnetic suction component are magnetically connected, the first sealing component seals the first through hole. A second sealing element, a fourth magnetic element, and a third magnetic element are sequentially disposed outside the output charging connector. When the third magnetic element and the fourth magnetic element are magnetically connected, the second sealing element seals the second through hole.

[0009] As an optional solution, the number of output lines is set to two, and both output lines extend into the interior of the housing along adjacent first through holes; In use, two output lines and an output charging connector are placed at intervals inside the box.

[0010] As an optional solution, the protective component includes: The first flange ring and the second flange ring are disposed outside the housing; A third sealing element and a partition are sequentially connected to the inner side of the second flange ring, and the partition has multiple grooves.

[0011] As an optional solution, the energy storage component includes: The main board, battery cell, and coil are disposed inside the housing, and the battery cell is electrically connected to the output charging connector and the coil through the main board; When the coil is in an alternating magnetic field, a current is generated for charging and discharging the battery cell.

[0012] As an alternative, the housing includes: The bottom shell is used to support the energy storage component; The front shell is used to support the magnet. When the front shell and the bottom shell are closed, they form a closed space to separate the energy storage component from the external environment. A decorative shell is fixed to the outside of the faceplate.

[0013] As an alternative, the faceplate has a lamp hole, a lamp cap is glued inside the lamp hole, and an LED power lamp connected to the energy storage component is installed inside the lamp cap.

[0014] As an alternative, the shell has a keyhole, and a button that is electrically connected to the energy storage component is bonded inside the keyhole.

[0015] A method for dust and water protection of a portable power bank with a magnetically attached interface concealed structure, comprising the following steps: The user pulls the two output lines in opposite directions, causing the first seal and the output charging connector to enter the box until the first magnetic and second magnetic components are magnetically connected. The second magnetic component causes the first seal to press tightly against the inner wall of the box, so that the first seal seals the first through hole on the outside of the output line. The user inserts the second seal into the junction box until the third and fourth magnetic components are magnetically connected. The fourth magnetic component causes the second seal to press tightly against the inner wall of the junction box, so that the second seal seals the second through hole on the outside of the output charging connector.

[0016] The technical effects achieved by this invention are as follows: In this invention, two output lines are externally mounted, with corresponding output charging connectors inserted into the same junction box. The holes on both sides of the junction box are sealed with sealing elements to prevent dust and water from entering the casing. The two output lines intersect each other under the limiting effect of the junction box and the output charging connectors, continuously concealing the output charging connectors inside the junction box, thus blocking external impacts to the output charging connectors.

[0017] This invention adds two flange rings to the outside of the coil and magnet to achieve double-layer protection. The joint between the two flange rings is filled with waterproof adhesive, and the adhesive is dispersed through multiple grooves, which not only provides dust and water protection but also reduces air bubbles or defects in the adhesive.

Detailed Implementation

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0021] Example 1: like Figures 1-11 As shown, a dustproof and waterproof power bank system with a magnetically attached interface concealed structure includes a housing 1, an energy storage component 2 disposed inside the housing 1, an output charging connector connected to the energy storage component 2, a charging component 3 connected to the energy storage component 2, a magnet 4, and a protective component 5 disposed outside the housing 1. When the user carries the power bank, the charging component 3 is magnetically closed to separate the output charging connector from the external environment. When the user uses the power bank to charge a device, the charging component 3 is opened to expose the output charging connector to the external environment, and the device is connected to the output charging connector for charging. When the user is charging the power bank, the protective component 5 separates the magnet 4 from the external environment and places the energy storage component 2 in an alternating magnetic field to generate current for charging the energy storage component 2.

[0022] See attached document Figure 1 and Figure 2 The housing 1 includes a bottom shell 101, a front shell 102, and a decorative shell 103, see [link / reference]. Figure 5 The bottom shell 101 is used to support the energy storage module 2, see [reference]. Figure 6 The face shell 102 is used to support the magnet 4. When the face shell 102 and the bottom shell 101 are closed, the joint between them is coated with waterproof adhesive (e.g., epoxy resin) to form a closed space. This closed space is used to separate the energy storage component 2 from the external environment. See [link to relevant documentation]. Figure 7 The decorative shell 103 is fixed to the outside of the face shell 102 to form a preset pattern.

[0023] See attached document Figure 2 , Figure 6 and Figure 10 The faceplate 102 has a lamp hole 104, and a lamp cap 106 is glued inside the lamp hole 104. An LED power lamp connected to the energy storage component 2 is installed inside the lamp cap 106. When the energy storage component 2 is powered on and the LED power lamp is powered on, the LED power lamp emits light to indicate the working status of the energy storage component 2.

[0024] See attached document Figure 6 , Figure 9 and Figure 10 The faceplate 102 has a keyhole 105, and a button 107 electrically connected to the energy storage component 2 is glued inside the keyhole 105. When the user presses the button 107, if the energy storage component 2 is working normally, the LED power light will be lit and emit light. If the energy storage component 2 is not working normally, the LED power light will not be lit.

[0025] See attached document Figure 2 , Figure 3 and Figure 10 The energy storage component 2 includes a main board 201, a battery cell 202, and a coil 203 disposed inside the housing 1. The battery cell 202 is electrically connected to the output charging connector and the coil 203 through the main board 201. When the coil 203 is in an alternating magnetic field, a current is generated for charging and discharging the battery cell 202. When the output charging connector is connected to an external device to be charged, the user presses button 107, the LED power light is lit, and the battery cell 202 charges the external device to be charged along the output charging connector.

[0026] As an optional embodiment, the motherboard 201 is electrically connected to a USB charging port, which penetrates the housing 1. When carrying a power bank, the user inserts a waterproof sealing plug into the USB charging port to prevent dust or water from entering the USB charging port.

[0027] See attached document Figure 2 , Figure 3 and Figure 4 The charging component 3 includes an output cable 301 and a junction box 302. The output cable 301 is used to connect the energy storage component 2 to the output charging connector, and the junction box 302 is used to store the output charging connector, such as... Figure 1As shown, the two output lines 301 share a single junction box 302. (See attached diagram) Figure 11 Two output charging connectors are spaced apart inside the junction box 302. When the output wire 301 is magnetically inserted into the junction box 302, it drives the output charging connector into the junction box 302. When the output wire 301 extends out of the junction box 302, it drives the output charging connector out of the junction box 302. The user can connect the output charging connector to an external device to be charged for charging.

[0028] See attached document Figure 3 and Figure 4 The junction box 302 includes a box body 3021, and two cavities are provided inside the box body 3021 at intervals. The two cavities are used to place two output lines 301 respectively. Meanwhile, the two ends of the box 3021 are respectively provided with a first through hole 3022 and a second through hole 3023. The two output wires 301 are respectively inserted into the box 302 along the first through hole 3022, and the output charging connectors are respectively inserted into the box 3021 along the second through hole 3023. The inner wall of the box 3021 is bonded with a first magnetic 3024 and a third magnetic 3027 at intervals. In addition, the box 3021 is equipped with a first sealing member 3026, a second magnetic 3025 embedded in the surface of the first sealing member 3026, a second sealing member 3029, and a fourth magnetic 3028 embedded in the surface of the second sealing member 3029. Since the first sealing member 3026 is bonded to the outside of the output line 301 in a ring shape, when the output line 301 moves, it can drive the first sealing member 3026 to move relative to the first through hole 3022. The second sealing member 3029 is inserted into the second through hole 3023. When the output charging connector moves, it pushes out the second sealing member 3029 in the second through hole 3023, so that the second through hole 3023 is open. When the first magnetic suction component 3024 and the second magnetic suction component 3025 are magnetically connected, the second magnetic suction component 3025 drives the first sealing component 3026 to press tightly against the inner wall of the box body 3021, so that the first sealing component 3026 seals the first through hole 3022 on the outside of the output line 301. When the third magnetic component 3027 and the fourth magnetic component 3028 are magnetically connected, the fourth magnetic component 3028 drives the second sealing component 3029 to press tightly against the inner wall of the box 3021, so that the second sealing component 3029 seals the second through hole 3023 on the outside of the output charging connector. At this time, the first seal 3026 and the second seal 3029 seal the housing 3021, so that the housing 3021 seals the output charging connector and the part connected to the output line 301, so that the output line 301 can be dustproof and waterproof when it is in the external environment of the housing 1, ensuring its subsequent charging conduction function and improving the stability of energy transmission of the battery cell 202 through the output line 301.

[0029] See attached document Figure 2, Figure 3 and Figure 4 The number of output lines 301 is set to two. Both output lines 301 extend into the box 3021 along the adjacent first through hole 3022. When the two output lines 301 move away from each other, the output charging connector is limited inside the box 302 to prevent the two output lines 301 from detaching from the box 302. At the same time, both output charging connectors are stored in the box 302 to achieve the function of resisting external impact.

[0030] See attached document Figure 2 , Figure 6 and Figure 8 The protective component 5 includes a first flange ring 501 and a second flange ring 502 disposed on the outside of the housing 1. During installation, since the housing 1 has a round hole that is directly opposite to the coil 203, the operator can fix the magnet 4 to the outer edge of the round hole through the plastic bracket, and then the second flange ring 502 and the first flange ring 501 are successively glued to the outside of the round hole so that the two cover the magnet 4, and the joint between the two is filled with waterproof glue to achieve a double-layer dustproof and waterproof function. Meanwhile, a third sealing element 5021 and a partition plate 5022 are sequentially bonded to the inner side of the second flange ring 502. The third sealing element 5021 is made of waterproof fabric cut by circumferential cutting. The partition plate 5022 is made of aluminum alloy and has multiple grooves 5023 on its surface. The grooves 5023 are used to accommodate waterproof adhesive, so that the waterproof adhesive is distributed at multiple points in the connection seam between the second flange ring 502 and the first flange ring 501, reducing air bubbles or defects in the waterproof adhesive. As an optional embodiment, wear-resistant glass is embedded in the middle of the first flange ring 501 to resist external impacts.

[0031] Example 2: like Figure 12 As shown, a method for dust and water protection of a power bank with a magnetic interface hidden structure, using the dust and water protection system for a power bank with a magnetic interface hidden structure provided in Embodiment 1, includes the following steps: The user pulls the two output lines 301 in opposite directions, causing the first seal 3026 and the output charging connector to enter the box 302 until the first magnetic suction member 3024 and the second magnetic suction member 3025 are magnetically connected. The second magnetic suction member 3025 causes the first seal 3026 to stick tightly to the inner wall of the box 3021, so that the first seal 3026 seals the first through hole 3022 on the outside of the output line 301. The user inserts the second seal 3029 into the junction box 302 until the third magnetic 3027 and the fourth magnetic 3028 are magnetically connected. The fourth magnetic 3028 drives the second seal 3029 to stick tightly to the inner wall of the box 3021, so that the second seal 3029 seals the second through hole 3023 on the outside of the output charging connector. At this time, the first seal 3026 and the second seal 3029 seal the housing 3021, so that the housing 3021 seals the output charging connector and the part connected to the output line 301, so that the output line 301 can be dustproof and waterproof when it is in the external environment of the housing 1, ensuring its subsequent charging conduction function and improving the stability of energy transmission of the battery cell 202 through the output line 301.

[0032] The above description is merely an optional embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
