[0001] This application relates to the field of energy storage equipment technology, and in particular to a wireless charging device and an energy storage device. Background Technology

[0002] Wireless charging for mobile phones is a charging method in which energy is transferred between a wireless charging device and the mobile phone through a magnetic field. The charging coil inside the mobile phone is usually located on the back of the phone, and the phone is in close contact with the wireless charging module of the wireless charging device during charging to ensure charging power.

[0003] However, the camera on the back of a mobile phone is usually quite protruding. For the sake of aesthetics, the wireless charging area on energy storage devices is usually designed as a flat structure. This makes it impossible for the charging coil area on the back of the phone to be in close contact with the wireless charging area of ​​the energy storage device's wireless charging module, resulting in reduced charging power or even failure to charge. Utility Model Content

[0004] The embodiments of this application aim to provide a wireless charging device and an energy storage device, so as to at least improve the problem that it is difficult for the device to be charged to be in close contact with the signal transmitting surface of the wireless charging module.

[0005] In order to solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions: In a first aspect, embodiments of this application provide a wireless charging device for installation in an opening of the housing of a device to be connected. The wireless charging device includes a mounting cover, a wireless charging module, and a movable support assembly. The mounting cover is fixedly fitted to the inner wall of the housing and covers the opening. The wireless charging module is housed within the opening and movably connected to the mounting cover, with the signal transmitting surface of the wireless charging module exposed through the opening. The movable support assembly connects the mounting cover and the wireless charging module. When the wireless charging module housed in the opening is pressed, the movable support assembly supports the wireless charging module to move upward relative to the mounting cover, so that the wireless charging module moves to a first position where the signal transmitting surface extends beyond the opening.

[0006] In some embodiments, the wireless charging module is provided with at least one hook, and the movable support component includes an elastic element and at least one push switch; one end of the elastic element is connected to the mounting cover and the other end is connected to the wireless charging module, and each push switch is fixedly disposed on the mounting cover and movably latched onto one of the hooks; when the wireless charging module received in the opening is pressed, the push switch disengages from the hook connected thereto, and the elastic element is used to support the wireless charging module to move upward relative to the mounting cover; when the wireless charging module in the first position is pressed downward, each push switch latches onto one of the hooks.

[0007] In some embodiments, the mounting cover is provided with a guide groove, and the wireless charging module is provided with a first annular wall, the first annular wall being slidably engaged with the inner wall of the guide groove.

[0008] In some embodiments, the wireless charging module has a second annular wall that surrounds the first annular wall and is spaced apart from the first annular wall, and one end of the elastic member is located between the first annular wall and the second annular wall; and / or, the mounting cover has a limiting annular groove at the bottom of the guide groove, and the other end of the elastic member abuts against the limiting annular groove.

[0009] In some embodiments, the wireless charging device further includes an elastic ring clamped between the inner wall of the guide groove and the first ring wall.

[0010] In some embodiments, the elastic element is ring-shaped, with one end of the elastic element surrounding the hook and the other end of the elastic element surrounding the push switch.

[0011] In some embodiments, the wireless charging module is provided with guide posts, the mounting cover is provided with guide grooves, and the guide posts and guide grooves are slidably engaged.

[0012] In some embodiments, the guide groove extends to the side of the mounting cover opposite to the housing, the guide post has a through hole extending from the end face of the guide post into the wireless charging module, and the guide groove and the through hole are used for cables to pass through.

[0013] In some embodiments, the outer peripheral surface of the wireless charging module is provided with a first limiting protrusion, and when the signal transmitting surface moves to the first position, the first limiting protrusion abuts against the inner wall of the housing.

[0014] Secondly, embodiments of this application provide an energy storage device, the energy storage device including a secondary battery and a wireless charging device as described in any embodiment of the first aspect; the secondary battery is disposed inside the housing and supplies power to the wireless charging module.

[0016] The wireless charging device and energy storage device of this application embodiment allow the wireless charging module to be housed in an opening of the housing and to move upward relative to the mounting cover, with the signal transmitting surface extending beyond the opening during the upward movement. Therefore, when the signal transmitting surface extends beyond the opening, it can be in close contact with the device to be charged, and the protruding portion of the device to be charged avoids the housing, thus improving the problem of the device to be charged not being able to be in close contact with the signal transmitting surface of the wireless charging module, and improving the problem of reduced charging power or even inability to charge the device.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Firstly, please refer to Figures 1 to 3 This application provides a wireless charging device 100, which is used to install itself into an opening in the housing of a device to be connected. For example, please refer to... Figure 6 The device to be connected is an energy storage device 200, which includes a housing 210 with an opening 211 through which a wireless charging device 100 is exposed, allowing it to charge the device outside the energy storage device 200. The device to be charged is a wirelessly charging device, such as a smartphone, smartwatch, drone, wireless mouse, or wireless power bank.

[0028] For the wireless charging device 100 described above, please refer to Figures 1 to 3 The wireless charging device 100 includes a mounting cover 1, a wireless charging module 2, and a movable support assembly 3. The mounting cover 1 is fixedly mounted to the inner wall of the housing 210 and covers the opening 211. The wireless charging module 2 is housed within the opening 211 and movably connected to the mounting cover 1, with its signal transmitting surface 21 exposed through the opening 211. The movable support assembly 3 connects the mounting cover 1 and the wireless charging module 2. The wireless charging module 2 generates a changing magnetic field, causing the device to be charged within the magnetic field to generate an induced current, thereby achieving charging. For example, the wireless charging module 2 contains an electromagnetic coil (not shown) and a circuit board (not shown). The circuit board is electrically connected to the electromagnetic coil. When power is supplied to the circuit board, the circuit board provides an alternating current to the electromagnetic coil, thereby exciting the electromagnetic coil to generate a changing magnetic field. The magnetic field strength is highest at the signal transmitting surface 21 of the wireless charging module 2. By ensuring close contact between the signal transmitting surface 21 and the device to be charged, the optimal charging effect is provided.

[0029] In related technologies, the wireless charging module 2 is embedded in the opening 211 and flush with the outer casing 210, making it difficult for devices with protruding parts to be charged to fit tightly against the signal emitting surface 21. For example, the camera on the back of a mobile phone is usually quite protruding, and the camera will press against the outer casing 210, making it impossible for the back of the phone to fit tightly against the signal emitting surface 21, resulting in reduced charging power or even no charging at all.

[0030] In this embodiment, when the wireless charging module 2 housed in the opening 211 is pressed, the movable support component 3 supports the wireless charging module 2 to move upward relative to the mounting cover 1, so that the wireless charging module 2 moves to a first position where the signal emitting surface 21 extends beyond the opening 211. That is, after the wireless charging module 2 moves upward relative to the mounting cover 1, the signal emitting surface 21 can extend beyond the opening 211. In this way, the signal emitting surface 21 can be in close contact with the device to be charged, and the protruding part of the device to be charged avoids the outer shell 210, improving the problem that the device to be charged cannot be in close contact with the signal emitting surface 21 of the wireless charging module 2, and improving the problem of reduced charging power or even inability to charge the device. It is understood that the height of the signal emitting surface 21 extending beyond the opening 211, for example, when the protruding part is the camera of a mobile phone, the height can be 2mm, 3mm, 4mm, 5mm, or 10mm, etc.

[0031] In some embodiments, the wireless charging module 2 is adapted to the opening 211. For example, see... Figure 1 and Figure 7 The opening 211 is circular, and the wireless charging module 2 is cylindrical or disc-shaped.

[0032] In some embodiments, please refer to Figures 2 to 5 The wireless charging module 2 is provided with at least one hook 22, and the movable support component 3 includes an elastic element 32 and at least one push switch 31; one end of the elastic element 32 is connected to the mounting cover 1 and the other end is connected to the wireless charging module 2, and each push switch 31 is fixedly mounted on the mounting cover 1 and movably latched onto a hook 22; when the wireless charging module 2 housed in the opening 211 is pressed, the push switch 31 disengages from the hook 22 connected thereto, and the elastic element 32 is used to support the wireless charging module 2 to move upward relative to the mounting cover 1; when the wireless charging module 2 in the first position is pressed downward, each push switch 31 latches onto a hook 22. For example, when the wireless charging module 2 is received in the opening 211, the two ends of the elastic member 32 are supported by the mounting cover 1 and the wireless charging module 2 respectively, and the elastic member 32 is in a compressed state. The press switch 31 is engaged with the hook 22 to tighten the wireless charging module 2. When the wireless charging module 2 received in the opening 211 is pressed, the press switch 31 disengages from the hook 22, and the elastic force of the elastic member 32 drives the wireless charging module 2 to move upward. When the wireless charging module 2 in the first position is pressed, the elastic member 32 is compressed, and the press switch 31 is engaged with the hook 22 again, thereby tightening the wireless charging module 2 and allowing the wireless charging module 2 to be received in the opening 211. Optionally, the mounting cover 1 is mounted to the housing 210 by screws. Optionally, the elastic member 32 is a spring. Optionally, the mounting cover 1 is provided with a mounting hole 11, and the press switch 31 is detachably mounted to the mounting cover 1 through the mounting hole 11. Optionally, there are two push switches 31, which are symmetrically arranged on the mounting cover 1.

[0033] The elastic element 32 supports the upward movement of the wireless charging module 2, acting as a buffer when placing the device to be charged, reducing impact force and minimizing damage to both the wireless charging module 2 and the device. It is understood that the press switch 31 switches between a locked and unlocked state after being pressed once. For example, when the press switch 31 is engaged with the hook 22, pressing the wireless charging module 2 once disengages the hook 22 from the press switch 31; when the press switch 31 is disengaged from the hook 22, pressing the wireless charging module 2 once re-engages the press switch 31 with the hook 22. By engaging or disengaging the press switch 31 with the hook 22 of the wireless charging module 2, the wireless charging module 2 can be pulled into the opening 211 of the outer casing 210, or released to move upward under the action of the elastic element 32. This allows for easy switching of the wireless charging module 2's position simply by pressing, simplifying operation and improving user experience.

[0034] When the wireless charging module 2 is housed in the opening 211, the signal emitting surface 21 can also extend beyond the opening 211, but the height extending beyond the opening 211 is less than the height of the signal emitting surface 21 extending beyond the opening 211 when the wireless charging module 2 is in the first position. This can improve the problem of the wireless charging module 2 protruding too much. Alternatively, the signal emitting surface 21 can be recessed into the opening 211, that is, the wireless charging module 2 is recessed into the outer shell 210, which is beneficial for protecting the wireless charging module 2. Please refer to [link / reference]. Figure 2 The signal transmitting surface 21 can be flush with the opening 211, that is, the wireless charging module 2 is flush with the outer surface of the shell 210, making the appearance of the energy storage device 200 flatter, easier to store, and more aesthetically pleasing.

[0035] In some embodiments, please refer to Figures 1 to 3 The elastic element 32 is ring-shaped, with one end surrounding the hook 22 and the other end surrounding the push switch 31. The ring-shaped elastic element 32 provides more balanced support to the wireless charging module 2, allowing the wireless charging module 2 to move vertically relative to the outer casing 210 under the action of the elastic element 32 and external force, reducing movement jamming caused by tilting of the wireless charging module 2. Furthermore, the two ends of the elastic element 32 surrounding the hook 22 and the push switch 31 respectively ensure that the pulling force of the push switch 31 on the wireless charging module 2 passes through the center of the elastic element 32, improving the problem of the wireless charging module 2 tilting relative to the outer casing 210 when housed in the opening 211, reducing jamming when pressing the wireless charging module 2, and improving aesthetics.

[0036] In some embodiments, please refer to Figure 3 and Figure 4The wireless charging module 2 is provided with a first limiting protrusion 23. When the wireless charging module 2 moves to the first position, the first limiting protrusion 23 abuts against the inner wall of the housing 210. For example, the first limiting protrusion 23 is annular, and the outer diameter of the first limiting protrusion 23 is larger than the inner diameter of the opening 211, so that it can abut against the inner wall of the housing 210 to cooperate with the elastic member 32 to limit the wireless charging module 2 to the first position.

[0037] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The mounting cover 1 has a guide groove 12, and the wireless charging module 2 has a first annular wall 24, which slides in conjunction with the inner wall of the guide groove 12. Exemplarily, the extending directions of the guide groove 12 and the first annular wall 24 are parallel to the movement direction of the wireless charging module 2. The first annular wall 24 passes through the guide groove 12 and engages with the shaft hole of the guide groove 12, so that the movement direction of the first annular wall 24 relative to the mounting cover 1 is the same as the movement direction of the wireless charging module 2 relative to the outer casing 210. The sliding engagement between the first annular wall 24 and the guide groove 12 enhances the stability of the wireless charging module 2's movement relative to the outer casing 210. Optionally, the first annular wall 24 is circular, and the guide groove 12 is cylindrical.

[0038] In some embodiments, please refer to Figures 2 to 4 The wireless charging module 2 has a second annular wall 25, which surrounds the first annular wall 24 and is spaced apart from the first annular wall 24. One end of the elastic member 32 is located between the first annular wall 24 and the second annular wall 25. The first annular wall 24 and the second annular wall 25 limit the position of the elastic member 32, improving the problem that the wireless charging module 2 cannot move normally to extend out of the outer shell 210 due to the movement of the elastic member 32. Optionally, both the first annular wall 24 and the second annular wall 25 are circular, and the central axis of the second annular wall 25 coincides with that of the first annular wall 24.

[0039] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The mounting cover 1 has a limiting annular groove 13 at the bottom of the guide groove 12, and the other end of the elastic member 32 abuts against the limiting annular groove 13. The limiting annular groove 13 limits the position of the elastic member 32, improving the problem that the wireless charging module 2 cannot move normally to extend out of the outer shell 210 due to the movement of the elastic member 32. Optionally, the limiting annular groove 13 is circular.

[0040] In some embodiments, please refer to Figures 1 to 3The wireless charging device 100 also includes an elastic ring 4, which is clamped between the inner wall of the guide groove 12 and the first ring wall 24. Exemplarily, the outer peripheral surface of the first ring wall 24 has a circumferentially formed mounting groove 241. The elastic ring 4 is fitted into the mounting groove 241 and partially protrudes from the outer peripheral surface of the first ring wall 24, thereby contacting the inner wall of the guide groove 12. This increases the damping of the sliding of the first ring wall 24 relative to the mounting cover 1, improving the problem of the wireless charging module 2 quickly ejecting the outer shell 210 under the elastic force of the elastic member 32 when the push switch 31 disengages from the hook 22, reducing noise, and reducing damage to the wireless charging module 2 and the outer shell 210. Optionally, the elastic ring 4 is a rubber ring.

[0041] In some embodiments, please refer to Figures 2 to 4 The push-button switch 31 and the guide groove 14 are both located at the bottom of the guide groove 12. The wireless charging module 2 isolates the space outside the housing 210 from the space inside the guide groove 12, improving the problem of liquid seeping into the energy storage device 200 from the guide groove 14 and the mounting hole 11 for installing the push-button switch 31, and enhancing the waterproof effect of the energy storage device 200.

[0042] In some embodiments, please refer to Figures 2 to 5 The wireless charging module 2 is provided with guide posts 26, and the mounting cover 1 is provided with guide grooves 14. The guide posts 26 and guide grooves 14 are slidably engaged. Exemplarily, the extending directions of the guide grooves 14 and guide posts 26 are parallel to the movement direction of the wireless charging module 2. The guide posts 26 pass through the guide grooves 14, and the guide posts 26 engage with the shaft holes of the guide grooves 14, so that the movement direction of the guide posts 26 relative to the mounting cover 1 is the same as the movement direction of the wireless charging module 2 relative to the mounting cover 1. The sliding engagement between the guide posts 26 and guide grooves 14 enhances the stability of the wireless charging module 2's movement relative to the housing 210. Multiple guide posts 26 and guide grooves 14 can be provided, each corresponding to the other in a sliding engagement. Optionally, there are two guide posts 26 and two guide grooves 14. Optionally, both the guide posts 26 and guide grooves 14 are cylindrical.

[0043] In some embodiments, please refer to Figure 5 The guide groove 14 is formed by an annular wall 15. Optionally, the guide groove 14 has a notch in the circumferential direction, for example, the annular wall 15 partially surrounds and forms the guide groove 14.

[0044] In some embodiments, the guide groove 14 extends to the side of the mounting cover 1 opposite to the outer casing 210, and the guide post 26 is provided with a through hole 261. The through hole 261 extends from the end face of the guide post 26 into the wireless charging module 2. The guide groove 14 and the through hole 261 are used for cable passage. Thus, one end of the wire can extend into the wireless charging module 2 through the through hole 261 and be electrically connected to the circuit board, and the other end of the wire can extend through the guide groove 14 to the side of the mounting cover 1 opposite to the outer casing 210, facilitating electrical connection with the secondary battery inside the outer casing 210.

[0045] Secondly, please refer to Figure 6 This application provides an energy storage device 200, which includes a secondary battery and a wireless charging device 100 as described in any embodiment of the first aspect. The secondary battery is disposed within a housing 210 and supplies power to the wireless charging module 2. The secondary battery is a rechargeable battery, such as a nickel-cadmium battery, lead-acid (or lead-acid) battery, lithium-ion battery, lithium iron phosphate battery, sodium-sulfur battery, and sodium-ion battery. The energy storage device 200 possesses the structural features and beneficial effects of the wireless charging device 100, which will not be elaborated here.

[0046] In some embodiments, please refer to Figure 6 and Figure 7 The energy storage device 200 also includes a housing 210, which has an opening 211 and a support wall 212 surrounding the opening 211. A nut post 213 is provided on the outside of the support wall 212. The mounting cover 1 has a mounting through hole 16 for fasteners to pass through, and the fasteners are threadedly connected to the nut post 213. The mounting cover 1 can be installed on the housing 210 using fasteners via the nut post 213 and the mounting through hole 16. The fasteners can be screws. The support wall 212 abuts against the side of the mounting cover 1 facing the housing 210 to seal the opening 211, improving the problem of liquid seeping into the interior of the energy storage device 200 from the gap between the edge of the opening 211 and the mounting cover 1, thus enhancing the waterproof effect of the energy storage device 200. Optionally, there are multiple nut posts 213 and mounting through holes 16, with multiple nut posts 213 surrounding the opening 211, and mounting through holes 16 corresponding one-to-one with nut posts 213, thereby enhancing the reliability of the connection between the mounting cover 1 and the outer shell 210.

[0047] In some embodiments, please refer to Figure 2 and Figure 5 The mounting cover 1 is provided with a second limiting protrusion 17, which abuts against the inner wall surface of the support wall 212. Exemplarily, the second limiting protrusion 17 extends along the inner wall surface of the support portion, and the second limiting protrusion 17 contacts the support wall 212 to form an annular sealing surface, enhancing the sealing effect on the opening 211. Furthermore, the second limiting protrusion 17 abutting against the inner wall surface of the support wall 212 can position the mounting cover 1 relative to the outer casing 210, facilitating the installation of the mounting cover 1.
