Description

Technical Field

[0001] This application relates to the technical field of structural combinations of a set of mutually insulated electrical connection elements, and more particularly to a concealed charging device. Background Technology

[0002] Electrical appliances play various important roles in social life, and their use generally requires a power source, such as a power strip. These charging devices typically provide multiple outlets for electrical connections, allowing appliances to be connected in parallel and thus connected to the power supply.

[0003] With the development of technology, some electronic devices in electrical products are equipped with wireless charging functions. How to enable wireless charging of charging devices is one of the research topics in the industry. Utility Model Content

[0004] To address the aforementioned technical issues, this application provides a hidden charging device equipped with a retractable wireless charging module, which can meet both wired connection and wireless charging requirements, while also facilitating the storage and concealment of the wireless charging module.

[0005] This application provides a concealed charging device, comprising: a housing having a receiving cavity and an opening communicating with the receiving cavity; a wireless charging module movably disposed in the housing, the wireless charging module being switchable between a stored state within the receiving cavity and a used state where it moves from the opening to the outside of the housing; wherein, when the wireless charging module is in the stored state, the wireless charging module is at least partially concealed within the housing; and a restraining component for restraining the wireless charging module within the receiving cavity when the wireless charging module is in the stored state.

[0006] In the technical solution of this application embodiment, the concealed charging device can meet the wireless charging needs of electronic devices because it is equipped with a wireless charging module. Since the wireless charging module can switch between a stored state and a usage state, when in the stored state, at least part of the wireless charging module can be stored and hidden within the housing's cavity, which both protects the wireless charging module and reduces the space occupied by the concealed charging device. When in the usage state, the concealed charging device can simultaneously meet the power supply needs of both wireless charging electronic devices and wired electrical appliances, making it convenient to use. Because a restraining component is provided to confine the wireless charging module within the cavity, the wireless charging module is less likely to detach from the cavity after being stored, maintaining a stable stored state and facilitating the concealment and portability of the wireless charging module.

[0007] In some embodiments, the constraint component includes a swing member and a slide groove disposed within the receiving cavity. The swing member is rotatably disposed on the wireless charging module and slides in engagement with the slide groove. The slide groove has a mating section extending along the sliding direction of the wireless charging module and a constraint section communicating with the mating section. When the wireless charging module is in the stored state, the swing member enters the constraint section through the mating section and is constrained by the constraint section.

[0008] Therefore, the swinging component can move together with the wireless charging module and slide along the mating section of the slide until it enters the constraint section of the slide and is constrained, thus allowing the wireless charging module to be constrained within the storage cavity in the stored state. In addition, during the process of switching the wireless charging module from the stored state to the use state, the swinging component can be locked at the end of the mating section to prevent the wireless charging module from detaching from the housing.

[0009] In some embodiments, the constraint segment has a bend, and when the wireless charging module is in the retracted state, the swing member is hooked onto the side wall of the bend.

[0010] Therefore, the bend in the constraint section can trap the swinging component, thus constraining it and consequently the wireless charging module. Releasing the hook from the swinging component releases the constraint on the wireless charging module, making it convenient to use.

[0011] In some embodiments, the constraint segment includes a constraint sub-segment protruding toward the mating segment and an inlet sub-segment and an outlet sub-segment located on both sides of the constraint sub-segment, respectively. The inlet sub-segment and the outlet sub-segment are respectively connected to the constraint sub-segment and the mating segment. When the wireless charging module is in the retracted state, the swing member is constrained by the constraint sub-segment.

[0012] Thus, the oscillating component sequentially passes through the import segment, constraint segment, and export segment, enabling the oscillating component to enter the constraint segment from the import segment and be constrained, and to enter the export segment from the constraint segment and be unconstrained.

[0013] In some embodiments, the constraint segment has a first sidewall and a second sidewall that are oppositely arranged and both protrude toward the mating segment; the inlet segment has a third sidewall and a fourth sidewall that are oppositely arranged; and the outlet segment has a fifth sidewall and a sixth sidewall that are oppositely arranged. The first sidewall, the third sidewall, and the fifth sidewall are located on the side where the constraint segment, the inlet segment, and the outlet segment are close to each other. The constraint segment also has an inlet and outlet that communicate with the mating segment, the inlet segment, and the outlet segment respectively. The inlet and outlet face the third sidewall so that the swing member entering the constraint segment through the inlet and outlet is guided into the inlet segment by contacting the third sidewall. / Or, the inlet segment further has a seventh sidewall that is connected to the second sidewall and the fourth sidewall respectively, the seventh sidewall protruding away from the mating segment, and the end of the constraint segment communicating with the inlet segment facing the seventh sidewall, so that the swing member entering the inlet segment is guided into the constraint segment by contact with the seventh sidewall; and / or, the outlet segment further has an eighth sidewall that is connected to the second sidewall and the sixth sidewall respectively, the eighth sidewall protruding away from the mating segment, and the bend of the first sidewall facing the eighth sidewall, so that the swing member entering the constraint segment is guided into the outlet segment by contact with the eighth sidewall.

[0014] Therefore, after leaving the mating section, the oscillating component will enter the inlet section under the guidance of the third side wall; after leaving the inlet section, it will enter the constraint section under the guidance of the seventh side wall; after leaving the constraint section, it will enter the outlet section under the guidance of the eighth side wall, and then enter the mating section from the outlet section. This allows the oscillating component to move unidirectionally in the order of the inlet section, constraint section, and outlet section, which reduces the probability of the oscillating component getting stuck on the slideway compared to the oscillating component randomly entering and exiting any side section of the constraint section.

[0015] In some embodiments, the wireless charging module includes a housing with a swing limiting port, through which the swing member passes.

[0016] Therefore, the swing limiting port restricts the swing angle of the swinging component, which can both meet the need for the swinging component to slide normally on the slide groove and reduce the probability of the swinging component leaving the slide groove.

[0017] In some embodiments, the concealed charging device further includes an elastic drive member. When the wireless charging module is in the stored state, the elastic drive member is compressed by the action of the wireless charging module. During the process of the wireless charging module switching from the stored state to the used state, the elastic drive member applies an elastic force to the wireless charging module to drive the wireless charging module to slide.

[0018] Therefore, after the wireless charging module is released from its constraints, the elastic drive component can automatically push the wireless charging module out without the user having to pull it out manually, which helps to improve the user experience.

[0019] In some embodiments, the wireless charging module includes a housing with a first protrusion, the housing including a second protrusion located within the receiving cavity, the first protrusion and the second protrusion being disposed opposite to each other along the sliding direction of the wireless charging module, and the elastic drive member being located between the first protrusion and the second protrusion.

[0020] Therefore, when the wireless charging module is in its retracted state, the small distance between the first and second protrusions presses against the elastic drive member, causing the elastic drive member to store elastic force. During the transition from the retracted state to the usage state, the elastic drive member releases elastic force onto the first protrusion, pushing it away from the second protrusion, thus ejecting the wireless charging module. Furthermore, the first protrusion can abut against the housing near the opening, preventing the wireless charging module from popping out of the receiving cavity.

[0021] In some embodiments, the concealed charging device further includes a limiting member disposed within the receiving cavity, the limiting member having a limiting cavity and a clearance opening communicating with the limiting cavity; or, the limiting member and the housing together enclose a limiting cavity and a clearance opening communicating with the limiting cavity within the receiving cavity; the elastic drive member and the second protrusion are located within the limiting cavity, the first protrusion extending into the limiting cavity through the clearance opening; and / or, at least one of the first protrusion and the second protrusion has a limiting post protruding towards each other, the elastic drive member being sleeved on the limiting post; and / or, the concealed charging device further includes a buffer pad located on the side of the first protrusion opposite to the elastic drive member.

[0022] Because the elastic actuator is confined within the limiting cavity, it is less prone to displacement during deformation, thus providing a stable elastic force. Since the elastic actuator is sleeved on the limiting post, it can be fixed relative to the first protrusion and / or the second protrusion, preventing displacement during deformation and ensuring a stable elastic force. Because a buffer pad is provided on the side of the first protrusion opposite to the elastic actuator, when the first protrusion is ejected by the elastic actuator and impacts the housing, the buffer pad reduces impact noise and mitigates damage.

[0023] In some embodiments, the limiting member includes a limiting body and a first protrusion protruding from one side of the limiting body. The housing has a second protrusion protruding from the inner wall surface of the receiving cavity. The second protrusion and the first protrusion are located between the limiting body and the inner wall surface. The first protrusion, the second protrusion, the limiting body, and the inner wall surface together enclose the limiting cavity. The second protrusion and the limiting body are spaced apart so that the gap forms the avoidance opening.

[0024] Therefore, in the sliding direction perpendicular to the wireless charging module, the first and second protrusions can limit the elastic limiting member from both sides of the elastic drive member, preventing the elastic drive member from deviating from the compression direction and bending to the side during compression, so that the elastic drive member can provide stable elastic force.

[0025] In some embodiments, the concealed charging device further includes a fastener, the housing having a mounting portion protruding from the inner wall of the receiving cavity, and the limiting member being fastened to the mounting portion by the fastener.

[0026] Therefore, the limiting component can be stably fixed on the inner wall surface of the housing.

[0027] In some embodiments, the mounting portion has a first mounting hole, and the limiting member includes a limiting body having a second mounting hole and a first protrusion and a second protrusion protruding from the same side of the limiting body. The first protrusion and the second protrusion are spaced apart so that a mounting groove communicating with the second mounting hole is formed at the interval. The mounting portion extends into the mounting groove, and the first mounting hole communicates with the second mounting hole. The fastener passes through the first mounting hole and the second mounting hole.

[0028] Therefore, the limiting component can be stably fixed on the inner wall surface of the housing.

[0029] In some embodiments, the concealed charging device further includes two limiting members disposed within the receiving cavity. The two limiting members are laterally spaced along a direction perpendicular to the sliding direction of the wireless charging module, so that a limiting groove communicating with the opening is formed at the interval, and the wireless charging module is located within the limiting groove.

[0030] Therefore, the two limiting members can limit the sliding range of the wireless charging module from both sides, allowing the wireless charging module to slide along the extension direction of the limiting groove, and preventing the wireless charging module in the storage state from shaking randomly inside the housing.

[0050] The following is a detailed description of this application.

[0051] Electrical appliances play various important roles in social life, and their use generally requires a power source, such as a power strip. These charging devices typically provide multiple outlets for electrical connections, allowing appliances to be connected in parallel and thus connected to the power supply.

[0052] With the development of technology, some electronic devices in electrical products are equipped with wireless charging functions. How to enable wireless charging of charging devices is one of the research topics in the industry.

[0053] To address the aforementioned technical issues, this application provides a hidden charging device equipped with a retractable wireless charging module, which can meet both wired connection and wireless charging requirements, while also facilitating the storage and concealment of the wireless charging module.

[0054] Based on this design concept, this application provides a hidden charging device, which includes: a housing having a receiving cavity and an opening communicating with the receiving cavity; a wireless charging module movably disposed in the housing, the wireless charging module being switchable between a stored state within the receiving cavity and a used state where it moves from the opening to the outside of the housing; wherein, when the wireless charging module is in the stored state, the wireless charging module is at least partially hidden within the housing; and a restraining component for restraining the wireless charging module within the receiving cavity when the wireless charging module is in the stored state.

[0055] Equipped with a wireless charging module, the concealed charging device can meet the wireless charging needs of electronic devices. Since the wireless charging module can switch between a stored state and a usable state, when stored, at least partially concealed within the housing's cavity, protecting the module while minimizing the space occupied by the concealed charging device. When in use, it can simultaneously power both wirelessly charged and wired devices, offering convenience. The presence of a restraining component that keeps the module within the cavity prevents it from easily detaching, maintaining a stable stored state and facilitating its concealment and portability.

[0056] The following explanation is based on the accompanying drawings.

[0057] Figure 1 A top view of a concealed charging device with a wireless charging module in use, provided as an embodiment of this application; Figure 2 A bottom view of a concealed charging device with the concealed portion of the housing of a wireless charging module in use, as provided in an embodiment of this application; Figure 3 for Figure 2 A magnified view of part A in the middle; Figure 4 A perspective view of a concealed charging device with the concealed portion housing and outer shell of a wireless charging module in use, provided for an embodiment of this application; Figure 5 A bottom view of a concealed charging device with the concealed portion of the housing of a wireless charging module in a retracted state, as provided in an embodiment of this application. Figure 6 for Figure 5 A cross-sectional view along the BB direction; Figure 7 An exploded view of a concealed charging device with a concealed housing provided for an embodiment of this application.

[0058] This application provides a concealed charging device, such as... Figures 1 to 7 As shown, it includes: a housing 10 having a receiving cavity and an opening 11 communicating with the receiving cavity; a wireless charging module 20 movably disposed in the housing 10, the wireless charging module 20 being switchable between a stored state within the receiving cavity and a used state where it moves from the opening 11 to outside the housing 10; wherein, when the wireless charging module 20 is in the stored state, the wireless charging module 20 is at least partially hidden within the housing 10; and a restraining component 30 for restraining the wireless charging module 20 within the receiving cavity when the wireless charging module 20 is in the stored state.

[0059] The concealed charging device includes a housing 10, a wireless charging module 20, and a restraint component 30. The wireless charging module 20 is at least partially housed within the housing 10 and is movable relative to the housing 10. The restraint component 30 is disposed within the housing 10 and is used to restrain the wireless charging module 20 when it is retracted into the housing 10.

[0060] The housing 10 has a receiving cavity that can accommodate components such as circuit boards. An opening 11 is formed on one side wall of the housing 10, through which the receiving cavity communicates with the outside. The housing 10 has multiple sockets, which can be at least one of the following: two-prong sockets, three-prong sockets, USB interfaces, etc. A power cord is provided on the housing 10 for electrical connection to a power source. A cable with a USB interface may also be provided on the housing 10.

[0061] The wireless charging module 20 has a charging coil that can be electrically connected to a circuit board within the receiving cavity. At least a portion of the wireless charging module 20 is housed within the receiving cavity. The wireless charging module 20 is movably disposed on the housing 10 and is capable of sliding from the opening 11 toward or away from the receiving cavity.

[0062] The constraint component 30 is located inside the receiving cavity and is used to constrain the wireless charging module 20 within the receiving cavity.

[0063] The wireless charging module 20 can slide towards the receiving cavity. During this movement, more and more of the wireless charging module 20 is housed within the receiving cavity. After the wireless charging module 20 slides to a certain depth, the restraining component 30 restrains the wireless charging module 20, causing at least a portion of the wireless charging module 20 to be hidden within the housing 10 and maintained in a housed state. Releasing the restraint of the restraining component 30 from the wireless charging module 20 allows it to slide away from the receiving cavity, exposing the surface of the wireless charging module 20 used for wireless charging from within the housing 10. This state of the wireless charging module 20 can be considered its usage state, and electronic devices can be placed on this surface to achieve wireless charging.

[0064] Furthermore, when the wireless charging module 20 is in its retracted state, there is a gap between the wireless charging module 20 and the inner wall of the housing 10, which can be used to place circuit boards, winding structures for winding cables, etc., in order to make full use of the space of the housing cavity.

[0065] In the technical solution of this application embodiment, since a wireless charging module 20 is provided, the hidden charging device can meet the wireless charging needs of electronic devices. Because the wireless charging module 20 can switch between a stored state and a usage state, when the wireless charging module 20 is in the stored state, it can be at least partially stored and hidden within the receiving cavity of the housing 10, which both protects the wireless charging module 20 and reduces the space occupied by the hidden charging device. When the wireless charging module 20 is in the usage state, the hidden charging device can simultaneously meet the power supply needs of both wireless charging electronic devices and wired electrical appliances, making it convenient to use. Because a restraining component 30 is provided to constrain the wireless charging module 20 within the receiving cavity, the wireless charging module 20 is less likely to detach from the receiving cavity through the opening 11 after being stored, maintaining a stable stored state and facilitating the concealment and carrying of the wireless charging module 20.

[0066] In some embodiments, such as Figure 2 , Figure 4 and Figure 7 As shown, the constraint component 30 includes a swing member 31 and a slide groove 32 disposed in the receiving cavity. The swing member 31 is rotatably disposed on the wireless charging module 20 and slides in cooperation with the slide groove 32. The slide groove 32 has a mating section 321 extending along the sliding direction of the wireless charging module 20 and a constraint section 322 communicating with the mating section 321. When the wireless charging module 20 is in the retracted state, the swing member 31 enters the constraint section 322 through the mating section 321 and is constrained by the constraint section 322.

[0067] The constraint component 30 includes a swing member 31 and a slide groove 32. One end of the swing member 31 is slidably engaged with the slide groove 32, and the other end of the swing member 31 is rotatably connected to the wireless charging module 20. A bent section can be constructed on the swing member 31, so that the swing member 31 is L-shaped, S-shaped, etc. For example, the swing member 31 is constructed as a hook.

[0068] The slide 32 has a mating section 321 and a constraint section 322, which are interconnected. The mating section 321 is closer to the opening 11 than the constraint section 322. The extending direction of the mating section 321 is parallel to the sliding direction of the wireless charging module 20, and the extending direction of the constraint section 322 intersects the extending direction of the mating section 321. When the swing member 31 moves from the mating section 321 into the constraint section 322, the swing member 31 rotates relative to the wireless charging module 20. When the swing member 31 reaches the constraint position of the constraint section 322, it is constrained and no longer moves.

[0069] Pushing the wireless charging module 20 releases the constraint on the swing member 31, causing the swing member 31 to return from the constraint section 322 to the mating section 321. When the wireless charging module 20 is in use, the swing member 31 can be located at the end of the mating section 321, thus limiting the extension distance of the wireless charging module 20.

[0070] Therefore, the swing member 31 can move together with the wireless charging module 20 and slide along the mating section 321 of the slide groove 32 until it enters the constraint section 322 of the slide groove 32 and is constrained, so that the wireless charging module 20 can be constrained in the storage cavity in the storage state. In addition, during the process of switching the wireless charging module 20 from the storage state to the use state, the swing member 31 can be locked at the end of the mating section 321 to prevent the wireless charging module 20 from falling off the housing 10.

[0071] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the constraint segment 322 has a bend 32213. When the wireless charging module 20 is in the retracted state, the swing member 31 is hooked onto the side wall of the bend 32213.

[0072] The constraint section 322 is a closed loop segment, and both ends of the constraint section 322 are connected to the mating section 321. The constraint section 322 has a bend 32213 protruding towards the mating section 321. When the swing member 31 moves to the bend 32213, it can hook onto the side wall of the bend 32213.

[0073] Therefore, the bend 32213 of the constraint segment 322 can trap the swing member 31, thereby constraining the swing member 31 and thus constraining the wireless charging module 20. The constraint of the wireless charging module 20 can be released by unhooking the swing member 31, making it convenient to use.

[0074] In some embodiments, such as Figure 3 As shown, the constraint segment 322 includes a constraint sub-segment 3221 protruding towards the mating segment 321 and an inlet sub-segment 3222 and an outlet sub-segment 3223 located on both sides of the constraint sub-segment 3221, respectively. The inlet sub-segment 3222 and the outlet sub-segment 3223 are respectively connected to the constraint sub-segment 3221 and the mating segment 321. When the wireless charging module 20 is in the retracted state, the swing member 31 is constrained by the constraint sub-segment 3221.

[0075] Constraint segment 322 includes constraint sub-segment 3221, import sub-segment 3222, and export sub-segment 3223. The ends of import sub-segment 3222 and export sub-segment 3223 overlap and connect with mating segment 321. Import sub-segment 3222, constraint sub-segment 3221, and export sub-segment 3223 are connected end to end in sequence.

[0076] The extension direction of the import segment 3222 intersects the extension direction of the export segment 3223, and the extension direction of the mating segment 321 intersects the extension directions of both the import segment 3222 and the export segment 3223, forming an approximate Y-shape. The constraint segment 3221 faces the mating segment 321 directly and spans the ends of the import segment 3222 and the export segment 3223, and has a bend 32213 protruding towards the mating segment 321. When the wireless charging module 20 is in its retracted state, the swing member 31 hooks onto the bend 32213 of the constraint segment 3221 to achieve constraint.

[0077] Thus, the swing member 31 sequentially passes through the import segment 3222, the constraint segment 3221, and the export segment 3223, enabling the swing member 31 to enter the constraint segment 3221 from the import segment 3222 and be constrained, and to enter the export segment 3223 from the constraint segment 3221 and be released from the constraint.

[0078] In some embodiments, see continue to see Figure 3The constraint segment 3221 has a first sidewall 32211 and a second sidewall 32212 that are relatively arranged and both protrude toward the mating segment 321. The import segment 3222 has a third sidewall 32221 and a fourth sidewall 32222 that are relatively arranged. The export segment 3223 has a fifth sidewall 32231 and a sixth sidewall 32232 that are relatively arranged. The first sidewall 32211, the third sidewall 32221 and the fifth sidewall 32232 are relatively arranged. 2231 is located on the side where the constraint segment 3221, the guide segment 3222, and the exit segment 3223 are close to each other; the constraint segment 322 also has an inlet and outlet that communicate with the mating segment 321, the guide segment 3222, and the exit segment 3223 respectively, the inlet and outlet facing the third side wall 32221, so that the swing member 31 entering the constraint segment 322 through the inlet and outlet is guided into the guide segment 3222 by contacting the third side wall 32221; and / or, the guide segment 323... Sub-segment 3222 also has a seventh side wall 32223 that is connected to the second side wall 32212 and the fourth side wall 32222 respectively. The seventh side wall 32223 protrudes away from the mating segment 321. The end of the restraining sub-segment 3221 that communicates with the guiding sub-segment 3222 faces the seventh side wall 32223, so that the swing member 31 entering the guiding sub-segment 3222 is guided into the restraining sub-segment 3221 by contacting the seventh side wall 32223; and Alternatively, the leading subsection 3223 may also have an eighth side wall 32233 that is in contact with the second side wall 32212 and the sixth side wall 32232 respectively. The eighth side wall 32233 protrudes in a direction away from the mating section 321, and the bend 32213 of the first side wall 32211 faces the eighth side wall 32233, so that the swing member 31 entering the constraining subsection 3221 is guided into the leading subsection 3223 by contacting the eighth side wall 32233.

[0079] The swing member 31 can be confined between the first side wall 32211 and the second side wall 32212 and slide along the constraint segment 3221; the swing member 31 can be confined between the third side wall 32221 and the fourth side wall 32222 and slide along the guide segment 3222; the swing member 31 can be confined between the fifth side wall 32231 and the sixth side wall 32232 and slide along the exit segment 3223. The third side wall 32221, the first side wall 32211 and the fifth side wall 32231 are connected in sequence, and the three are located on the side where the constraint segment 3221, the guide segment 3222 and the exit segment 3223 are close to each other. The fourth side wall 32222, the second side wall 32212 and the sixth side wall 32232 are connected in sequence, and the four are located on the side away from each other of the constraint sub-segment 3221, the import sub-segment 3222 and the export sub-segment 3223.

[0080] In a specific embodiment, the junction of the constraint segment 322 and the mating segment 321 is referred to as the inlet and outlet. The third side wall 32221 faces the inlet and outlet, so that after the swing member 31 enters the constraint segment 322 from the inlet and outlet, it first contacts the third side wall 32221. As the third side wall 32221 enters between the third side wall 32221 and the fourth side wall 32222, that is, it enters the inlet sub-segment 3222.

[0081] In another specific embodiment, the import segment 3222 also has a seventh side wall 32223. The seventh side wall 32223 is opposite to the third side wall 32221, and the fourth side wall 32222, the seventh side wall 32223, the second side wall 32212, and the sixth side wall 32232 are connected sequentially. The seventh side wall 32223 protrudes away from the mating segment 321 relative to the fourth side wall 32222 and the second side wall 32212. The extending direction of the fourth side wall 32222 intersects the extending direction of the second side wall 32212, and the seventh side wall 32223 can be considered as the wall at the corner of the fourth side wall 32222 and the second side wall 32212. The seventh side wall 32223 faces the first side wall 32211. In the same projection plane perpendicular to the sliding direction of the wireless charging module 20, the seventh side wall 32223 and the first side wall 32211 partially overlap. After the swing member 31 disengages from the seventh side wall 32223, it first contacts the first side wall 32211. As the first side wall 32211 enters between the first side wall 32211 and the second side wall 32212, that is, it enters the constraint segment 3221. The swing member 31 moves with the constraint segment 3221 until it reaches the bend 32213 of the first side wall 32211. The swing member 31 can hook at this point and be constrained, preventing the wireless charging module 20 from sliding away from the receiving cavity and maintaining it in the stored state.

[0082] In another specific embodiment, the derived segment 3223 also has an eighth side wall 32233. The eighth side wall 32233 is opposite to the fifth side wall 32231, and the fourth side wall 32222, seventh side wall 32223, second side wall 32212, eighth side wall 32233, and sixth side wall 32232 are connected sequentially. The eighth side wall 32233 protrudes away from the mating segment 321 relative to the second side wall 32212 and the sixth side wall 32232. The extending direction of the second side wall 32212 intersects the extending direction of the sixth side wall 32232, and the eighth side wall 32233 can be considered as the wall at the corner of the second side wall 32212 and the sixth side wall 32232. The bend 32213 of the first side wall 32211 faces the eighth side wall 32233. Specifically, the bend 32213 of the first side wall 32211 is closer to the eighth side wall 32233 than the seventh side wall 32223, and / or, the bend 32213 of the second side wall 32212 is offset from the bend 32213 of the first side wall 32211 and is closer to the seventh side wall 32223 than the eighth side wall 32233. After the swing member 31 disengages from the bend 32213, it will first contact the eighth side wall 32233, and then enter the area between the fifth side wall 32231 and the sixth side wall 32232, that is, enter the exit segment 3223.

[0083] During the transition from the use state to the storage state of the wireless charging module 20, the module first moves deeper towards the receiving cavity. The swing member 31 enters from the inlet / outlet along the mating section 321, first contacting the third side wall 32221 and then entering the guide section 3222. When the wireless charging module 20 reaches its maximum depth, the swing member 31 abuts against the seventh side wall 32223. When the wireless charging module 20 is subjected to a force moving away from the receiving cavity, it slides away from the cavity, causing the swing member 31 to move from the seventh side wall 32223 to the third side wall 32221 and into the constraint section 3221. When the swing member 31 reaches the bend 32213 of the first side wall 32211, it is constrained and cannot continue to move away from the cavity, thus positioning the wireless charging module 20. When the constraint is released, a force is applied to the wireless charging module 20 in the direction of the receiving cavity, so that the wireless charging module 20 slides in the direction of the receiving cavity and drives the swing member 31 to contact the eighth side wall 32233 from the bend 32213 of the first side wall 32211 and enter the exit section 3223. At this time, the wireless charging module 20 is pulled outward and the swing member 31 returns to the mating section 321 from the exit section 3223.

[0084] Therefore, after leaving the mating section 321, the swing member 31 will enter the inlet section 3222 under the guidance of the third side wall 32221; after leaving the inlet section 3222, the swing member 31 will enter the constraint section 3221 under the guidance of the seventh side wall 32223; after leaving the constraint section 3221, the swing member 31 will enter the outlet section 3223 under the guidance of the eighth side wall 32233, and then enter the mating section 321 from the outlet section 3223. This allows the swing member 31 to move unidirectionally in the order of inlet section 3222, constraint section 3221, and outlet section 3223, which reduces the probability of the swing member 31 getting stuck on the slide 32 compared to the swing member 31 randomly entering and exiting any side section of the constraint section 322.

[0085] In some embodiments, such as Figure 4 As shown, the wireless charging module 20 includes a housing 21 with a swing limiting port 211, and the swing member 31 passes through the swing limiting port 211.

[0086] The wireless charging module 20 includes a housing 21, in which a charging coil is placed. A swing limiting opening 211 is provided on the side of the housing 21 near the receiving cavity. A part of the swing member 31 is placed in the housing 21 and rotatably connected to the housing 21, while the other part extends out of the housing 21 from the swing limiting opening 211 and slides into the groove 32.

[0087] Optionally, the swing member 31 can rotate within a range of 60 degrees under the restriction of the swing limiting port 211.

[0088] Therefore, the swing limiting port 211 restricts the swing angle of the swing member 31, which can both meet the need for the swing member 31 to slide normally on the slide groove 32 and reduce the probability of the swing member 31 disengaging from the slide groove 32.

[0089] In some embodiments, such as Figure 2 and Figure 4 As shown, the hidden charging device also includes an elastic drive member 40. When the wireless charging module 20 is in the retracted state, the elastic drive member 40 is compressed under the action of the wireless charging module 20. During the process of switching the wireless charging module 20 from the retracted state to the use state, the elastic drive member 40 applies elastic force to the wireless charging module 20 to drive the wireless charging module 20 to slide.

[0090] For example, the elastic drive element 40 is a spring.

[0091] Therefore, after the wireless charging module 20 is released from its constraints, the elastic drive component 40 can automatically push out the wireless charging module 20 without the user having to pull it out manually, which helps to improve the user experience.

[0092] In some embodiments, the housing 10 includes a second protrusion 12 located within the receiving cavity. The second protrusion 12 protrudes from the inner wall surface of the housing 10. Along the sliding direction of the wireless charging module 20, the second protrusion 12 is located on the side of the wireless charging module 20 away from the opening 11 and is spaced apart from the wireless charging module 20. One end of the elastic drive member 40 abuts against or connects to the wireless charging module 20, and the other end of the elastic drive member 40 abuts against or connects to the wireless charging module 20.

[0093] In some embodiments, such as Figure 2 , Figure 4 and Figure 7 As shown, the wireless charging module 20 includes a housing 21 with a first protrusion 212, and the housing 10 includes a second protrusion 12 located in the receiving cavity. Along the sliding direction of the wireless charging module 20, the first protrusion 212 and the second protrusion 12 are arranged opposite to each other, and the elastic drive member 40 is located between the first protrusion 212 and the second protrusion 12.

[0094] The wireless charging module 20 includes a housing 21, on which a first protrusion 212 is provided. A second protrusion 12 is provided within the receiving cavity of the housing 10. On the same projection plane perpendicular to the sliding direction of the wireless charging module 20, the projections of the first protrusion 212 and the second protrusion 12 coincide. One end of the elastic drive member 40 abuts against or connects to the first protrusion 212, and the other end of the elastic drive member 40 abuts against or connects to the second protrusion 12.

[0095] Furthermore, the housing wall surrounding the opening 11 is located on the sliding path of the first protrusion 212. As the wireless charging module 20 slides away from the receiving cavity, the first protrusion 212 contacts the housing wall surrounding the opening 11 and limits the wireless charging module 20, preventing the wireless charging module 20 from completely detaching from the receiving cavity from the opening 11.

[0096] Therefore, when the wireless charging module 20 is in the retracted state, the small distance between the first protrusion 212 and the second protrusion 12 presses against the elastic drive member 40, causing the elastic drive member 40 to store elastic force. During the process of switching the wireless charging module 20 from the retracted state to the use state, the elastic drive member 40 releases elastic force towards the first protrusion 212, pushing the first protrusion 212 away from the second protrusion 12, thereby pushing the wireless charging module 20 out. Furthermore, the first protrusion 212 can abut against the housing 10 near the opening 11 to prevent the wireless charging module 20 from popping out of the receiving cavity.

[0097] In some embodiments, such as Figures 5 to 7As shown, the concealed charging device also includes a limiting member 50 disposed within the receiving cavity. The limiting member 50 has a limiting cavity and a clearance opening 51 communicating with the limiting cavity. Alternatively, the limiting member 50 and the housing 10 together form a limiting cavity and a clearance opening 51 communicating with the limiting cavity within the receiving cavity. The elastic drive member 40 and the second protrusion 12 are located within the limiting cavity. The first protrusion 212 extends into the limiting cavity through the clearance opening 51. And / or, at least one of the first protrusion 212 and the second protrusion 12 has a limiting post 60 protruding towards each other. The elastic drive member 40 is sleeved on the limiting post 60. And / or, the concealed charging device also includes a buffer pad located on the side of the first protrusion 212 opposite to the elastic drive member 40.

[0098] The concealed charging device also includes a limiting member 50. The limiting member 50 is disposed within the receiving cavity. In the sliding direction perpendicular to the wireless charging module 20, the limiting member 50 is located on at least one side of the wireless charging module 20. The limiting member 50 has a limiting cavity, and an avoidance opening 51 can be formed on the wall surface of the limiting member 50 facing the wireless charging module 20; alternatively, the limiting member 50 can be covered on the inner wall surface of the housing 10, with the limiting member 50 and the housing 10 together forming the limiting cavity and the avoidance opening 51. The avoidance opening 51 extends along the sliding direction of the wireless charging module 20 and communicates with the limiting cavity.

[0099] Furthermore, two limiting members 50 may be provided. In the sliding direction perpendicular to the wireless charging module 20, the two limiting members 50 are respectively provided on both sides of the wireless charging module 20.

[0100] Both the second protrusion 12 and the elastic drive member 40 are located within the limiting cavity. The first protrusion 212 passes through the clearance opening and is partially located within the limiting cavity. The first protrusion 212 can slide relative to the limiting member 50 along the sliding direction of the wireless charging module 20, while the second protrusion 12 is fixed relative to the limiting member 50. The elastic drive member 40 is located between the first protrusion 212 and the second protrusion.

[0101] A limiting post 60 may be provided on the surface of the first protrusion 212 facing the second protrusion 12, or the limiting post 60 may be provided on the surface of the second protrusion 12 facing the first protrusion 212. The elastic drive member 40 is sleeved on the limiting post 60, so that the elastic drive member 40 is fixed relative to the first protrusion 212 and / or the second protrusion 12.

[0102] The concealed charging device also includes a cushioning pad. The cushioning pad is disposed on the side surface of the first protrusion 212 facing the opening 11. Exemplarily, the cushioning pad is made of a deformable material such as silicone.

[0103] Because the elastic drive member 40 is confined within the limiting cavity, it is less prone to displacement during deformation, thus providing a stable elastic force. Since the elastic drive member 40 is sleeved on the limiting post 60, it can be fixed relative to the first protrusion 212 and / or the second protrusion 12, preventing displacement during deformation and ensuring a stable elastic force. Because a buffer pad is provided on the side of the first protrusion 212 opposite to the elastic drive member 40, when the first protrusion 212 is ejected by the elastic drive member 40 and impacts the housing 10, the buffer pad reduces impact noise and mitigates damage.

[0104] In some embodiments, such as Figure 6 and Figure 7 As shown, the limiting member 50 includes a limiting body 52 and a first protrusion 53 protruding from one side of the limiting body 52. ​​The housing 10 has a second protrusion 13 protruding from the inner wall surface of the receiving cavity. The second protrusion 13 and the first protrusion 53 are located between the limiting body 52 and the inner wall surface. The first protrusion 53, the second protrusion 13, the limiting body 52 and the inner wall surface together form a limiting cavity. The second protrusion 13 and the limiting body 52 are spaced apart so that the gap forms an avoidance opening 51.

[0105] The limiting member 50 includes a limiting body 52 and a first protrusion 53. The housing 10 has a second protrusion 13 protruding from the inner wall of the receiving cavity. The limiting body 52 covers the second protrusion 13, and the first protrusion 53 protrudes from the side wall of the limiting body 52 facing the second protrusion 13 and is offset from the second protrusion 13. The first protrusion 53, the second protrusion 13, the limiting body 52, and the inner wall of the housing 10 together form a limiting cavity.

[0106] The second protrusion 13 is closer to the wireless charging module 20 than the first protrusion 53. There is a gap between the second protrusion 13 and the limiting body 52, and an avoidance opening 51 is formed at the gap.

[0107] Therefore, in the sliding direction perpendicular to the wireless charging module 20, the first protrusion 53 and the second protrusion 13 can limit the elastic limiting member 50 from both sides of the elastic driving member 40, preventing the elastic driving member 40 from deviating from the compression direction and bending to the side during compression, so that the elastic driving member 40 can provide stable elastic force.

[0108] In some embodiments, the concealed charging device further includes fasteners, and the housing 10 has a mounting portion 14 protruding from the inner wall of the receiving cavity, and the limiting member 50 is fastened to the mounting portion 14 by fasteners.

[0109] The concealed charging device also includes fasteners. The housing 10 has a mounting portion 14 protruding from the inner wall of the receiving cavity, and the fastener passes sequentially through the limiting member 50 and the mounting portion 14 to secure them together. Exemplarily, the fastener is a screw, and the mounting portion 14 has a threaded hole.

[0110] Therefore, the limiting member 50 can be stably fixed on the inner wall surface of the housing 10.

[0111] In some embodiments, such as Figure 6 and Figure 7 As shown, the mounting part 14 has a first mounting hole, and the limiting member 50 includes a limiting body 52 with a second mounting hole and a first protrusion 53 and a second protrusion 13 protruding from the same side of the limiting body 52. ​​The first protrusion 53 and the second protrusion 13 are spaced apart so that a mounting groove communicating with the second mounting hole is formed at the interval. The mounting part 14 extends into the mounting groove, and the first mounting hole communicates with the second mounting hole. Fasteners are inserted into the first mounting hole and the second mounting hole.

[0112] The mounting part 14 extends into the mounting groove and is positioned between the first protrusion 53 and the second protrusion 13. Fasteners are inserted into the first mounting hole and the second mounting hole, fixing the limiting member 50 to the inner wall of the housing 10.

[0113] Therefore, the limiting member 50 can be stably fixed on the inner wall surface of the housing 10.

[0114] In some embodiments, such as Figures 5 to 7 As shown, the hidden charging device also includes two limiting members 50 disposed in the receiving cavity. The two limiting members 50 are arranged laterally at intervals perpendicular to the sliding direction of the wireless charging module 20, so that the interval forms a limiting groove communicating with the opening 11, and the wireless charging module 20 is located in the limiting groove.

[0115] The wireless charging module 20 is constrained between two limiting members 50. A limiting groove is formed between the two limiting members 50 and communicates with the opening 11. The wireless charging module 20 moves in and out of the opening 11 along the limiting groove to prevent the wireless charging module 20 from deviating from the opening 11 and getting stuck when it slides.

[0116] Thus, the two limiting members 50 can limit the sliding range of the wireless charging module 20 from both sides, so that the wireless charging module 20 slides along the extension direction of the limiting groove, and the wireless charging module 20 in the storage state will not shake freely inside the housing 10.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
