Description

Technical Field

[0001] This invention relates to the field of charger technology, and in particular to an AC plug opening structure and a mobile phone charger. Background Technology

[0002] Portable chargers, as common power supply accessories for electronic devices, often feature foldable AC plugs for easy storage and carrying. Existing foldable AC plugs typically require users to insert their fingers into the gap between the casing and the plug to manually pry or pry the plug open or fold it, relying on direct force from their fingers on the metal parts of the plug during the operation.

[0003] The applicant has discovered at least the following technical problems in the existing technology: the prying operation feels stiff and requires effort, resulting in a poor user experience. Especially for female users who wear manicures or have long nails, long nails are prone to getting stuck in the gaps and are difficult to pry off, which not only makes the operation inconvenient but may also cause the manicure to break or the nails to be damaged, further reducing the user-friendliness. Summary of the Invention

[0004] The purpose of this invention is to provide an AC plug opening structure and a mobile phone charger to solve the technical problems of existing foldable AC plugs, which require users to insert their fingers into the gap between the housing and the plug to manually pry and turn the plug. This is inconvenient and may also lead to nail breakage and nail damage. The various technical effects of the preferred solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An AC plug opening structure includes a housing, a plug assembly, and an auxiliary opening assembly. The housing has a receiving space and a limiting space. The two ends of the plug assembly form a first connecting end and a first movable end, respectively. The two ends of the auxiliary opening assembly form a second connecting end and a second movable end, respectively. The first connecting end and the second connecting end are movably connected and are movably connected to the limiting space. The first movable end and the second movable end can be simultaneously housed inside the receiving space. The second movable end can drive the first movable end to rotate outward synchronously and can also rotate inward independently and be housed inside the receiving space.

[0007] Preferably, the pin assembly includes a rotating member and two insert bodies, each of the two parallel insert bodies having one end connected to the rotating member and forming the first connecting end together with the rotating member, and the ends of the two insert bodies away from the rotating member forming the first movable end together.

[0008] Preferably, the auxiliary opening component has a mating groove at a corresponding position on the end of each insert body away from the rotating member. The end of the insert body away from the rotating member can be placed in the corresponding mating groove. The bottom surface of the mating groove can support the end of the insert body away from the rotating member. When the auxiliary opening component is rotated outward, the mating groove can drive the insert body to rotate outward synchronously.

[0009] Preferably, the auxiliary opening assembly includes an end connector and a rotating arm. Each end of the end connector is connected to one end of one of the rotating arms and together they form the second movable end. The other ends of the two rotating arms are rotatably connected to the rotating member and form the second connecting end. Two mating grooves are symmetrically formed on the inner side of the end connector.

[0010] Preferably, the outer side of the end connector is provided with a support structure.

[0011] Preferably, the rotating component includes a first rotating shaft, a rotating block, and a second rotating shaft. Each end of the first rotating shaft is connected to a rotating block, and each rotating block is connected to a second rotating shaft at an end away from the first rotating shaft. The first rotating shaft is rotatably connected to the limiting space, the rotating block is connected to the insert body, the rotating arm has a rotating hole that is rotatably connected to the second rotating shaft, and the rotating arm has a clearance groove for avoiding the rotating block.

[0012] Preferably, the housing includes a top cover and a fixing plate. The top cover is provided with a storage groove, which forms the receiving space. The fixing plate is connected to the top cover. The top cover is provided with a limiting groove, which, together with the fixing plate, forms the limiting space.

[0013] Preferably, it further includes spring clips, two of which are connected between the top cover and the fixing plate and correspond to the two insert bodies respectively, with the contact end of the spring clip elastically raised located below the end of the insert body connected to the rotating member.

[0014] Preferably, the receiving groove includes an end groove and two side grooves connected to the end groove. The end groove is used to receive the end connector, and the side grooves are used to receive the insert body and the rotating arm.

[0015] A mobile phone charger, including the aforementioned AC plug opening structure.

[0016] The beneficial effects of this invention are as follows: By adding an auxiliary opening component, the AC plug can be opened by the auxiliary opening component during the unfolding process. The auxiliary opening component can also be stored separately, without taking up space and avoiding affecting normal use. Throughout the process, the user will not touch the hardware of the plug component. This is more user-friendly than the existing method of directly prying and turning the AC plug by hand. It is especially suitable for female users who wear manicures or have long nails. The operation is convenient and less strenuous, avoiding situations such as broken manicures and damaged nails, and effectively improving the user experience. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] In the description of this invention, it should be understood that the terms "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0022] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Reference Figures 1 to 7 The present invention provides an AC plug opening structure, including a housing 1, a plug assembly 2 and an auxiliary opening assembly 3.

[0024] The housing 1 is provided with a receiving space and a limiting space. The two ends of the plug assembly 2 form a first connecting end and a first movable end, respectively. The two ends of the auxiliary opening assembly 3 form a second connecting end and a second movable end, respectively.

[0025] The first connecting end is movably connected to the second connecting end and is also movably connected to the limiting space. The first connecting end and the second connecting end can serve as the rotation axis of the first movable end and the second movable end, respectively.

[0026] The first movable end and the second movable end can be simultaneously stored inside the receiving space. The second movable end can drive the first movable end to rotate outward synchronously and unfold, and can also rotate inward independently and be stored inside the receiving space.

[0027] In actual use, the user's hand will only touch the auxiliary opening component 3, and will not touch the pin component 2. The hand applies force to the auxiliary opening component 3, causing the second movable end of the auxiliary opening component 3 to rotate outward and unfold.

[0028] At the same time, the first movable end of the plug assembly 2 rotates outward synchronously and unfolds. After rotating to the limit position, the plug assembly 2 can be in a fully unfolded state. At this time, the plug assembly 2 can be used normally and form a connection with the external power supply.

[0029] Furthermore, the auxiliary opening component 3 also has a separate storage function. It can rotate inward independently without changing the unfolded state of the pin component 2 and be stored inside the storage space. This setting does not damage the original external structure and will not affect normal use due to the addition of the auxiliary opening component 3, making the structural layout more reasonable.

[0030] With the addition of auxiliary opening component 3, the AC plug pins can be unfolded by driving the plug pin component 2 during the unfolding process. Auxiliary opening component 3 can also be stored separately, saving space and avoiding any impact on normal use. Throughout the process, the user will not touch the hardware of the plug pin component 2. This is more user-friendly than the existing method of directly prying or bending the AC plug pins by hand, especially suitable for female users who wear manicures or have long nails. It is convenient and less strenuous to operate, avoiding situations such as broken manicures or damaged nails, and effectively improving the user experience.

[0031] As an optional implementation, the pin assembly 2 includes a rotating member 21 and two insert bodies 22. The number of insert bodies 22 is two and they are arranged in parallel. Each insert body 22 has one end connected to the rotating member 21. The connection ends of the two insert bodies 22 and the rotating member 21 can together form a first connection end, which is movably connected to a second connection end and to a limiting space.

[0032] At the same time, the ends of the two inserts 22 that are away from the rotating part 21 together form the first movable end, which cooperates with the second movable end.

[0033] As an optional implementation, the auxiliary opening component 3 is provided with a mating groove 311 at a corresponding position on the end of each insert body 22 away from the rotating member 21. The end of the insert body 22 away from the rotating member 21 can be placed in the corresponding mating groove 311. The size of the mating groove 311 matches the size of the insert body 22. The bottom surface of the mating groove 311 can support the end of the insert body 22 away from the rotating member 21.

[0034] During the outward rotation of the auxiliary opening component 3, the mating groove 311 can drive the insert body 22 to rotate outward synchronously, thereby driving the entire pin assembly 2 to rotate outward. When rotated to the limit position, the pin assembly 2 can be in a fully unfolded state, at which point it can be used normally and can be connected to an external power source.

[0035] As an optional implementation, the auxiliary opening component 3 includes an end connector 31 and a rotating arm 32. Each end of the end connector 31 is connected to one end of a rotating arm 32. Preferably, the connection is integral, so that the auxiliary opening component 3 can be integrally formed and has good structural strength. At the same time, the above structures can together form the second movable end.

[0036] The other ends of both rotating arms 32 are rotatably connected to the rotating member 21 and form a second connecting end.

[0037] Two mating grooves 311 are symmetrically provided on the inner side of the end connector 31.

[0038] As an optional implementation, an assist structure 312 is provided on the outer side of the end connector 31. When the user uses the auxiliary opening component 3 to drive the pin component 2 to rotate, the user's hand will make actual contact with the assist structure 312. With the assistance of the assist structure 312, the auxiliary opening component 3 can be driven to rotate outward and unfold, making the whole operation process easier.

[0039] In this embodiment, the assistive structure 312 preferably includes multiple anti-slip patterns arranged side by side. The anti-slip patterns can effectively increase the friction between the user's hand and the end connector 31, making it more labor-saving.

[0040] As an optional implementation, the rotating member 21 includes a first rotating shaft portion 211, a rotating block 212, and a second rotating shaft portion 213. Each end of the first rotating shaft portion 211 is connected to a rotating block 212, and each end of the rotating block 212 away from the first rotating shaft portion 211 is connected to a second rotating shaft portion 213.

[0041] The first rotating shaft 211 cooperates with the limiting space, so that the first rotating shaft 211 is rotatably connected to the limiting space, and the first rotating shaft 211 can achieve relative rotation within the area limited by the limiting space.

[0042] The rotating block 212 is connected to the insert body 22.

[0043] The rotating arm 32 has a rotating hole 321, which is rotatably connected to the second rotating shaft 213. The size of the rotating hole 321 is preferably slightly larger than the size of the second rotating shaft 213, so that the two mainly form a guiding and positioning function, and will not generate a large friction force during rotation. This avoids the second movable end from generating friction force on the rotating part 21 and the insert body 22 during the process of rotating inward and being stored in the receiving space, and avoids driving the insert assembly 2 to rotate inward synchronously.

[0044] The rotating arm 32 is provided with a clearance groove 322 for avoiding the rotating block 212, which makes the structural design more reasonable, the rotating arm 32 and the rotating part 21 more compact, and reduces the space occupied.

[0045] As an optional implementation, the housing 1 includes a top cover 11 and a fixing plate 12. The top cover 11 is provided with a storage groove 111, which forms a receiving space. The fixing plate 12 is connected to the top cover 11, and the top cover 11 is provided with a limiting groove 112, which, together with the fixing plate 12, forms a limiting space.

[0046] In this embodiment, the top cover 11 and the fixing plate 12 are preferably connected by bolts. This arrangement allows the top cover 11 and the fixing plate 12 to form a split structure, which facilitates the overall assembly of the AC plug opening structure and makes disassembly and assembly more convenient and quick.

[0047] In the specific assembly process, the top cover 11, the pin assembly 2 and the auxiliary opening assembly 3 can be assembled first, and then the fixing plate 12 can be connected to the top cover 11 to complete the overall installation of the AC pin opening structure.

[0048] In this embodiment, in addition to the top cover 11 and the fixing plate 12, the housing 1 preferably also includes a main housing 13, which is connected to the top cover 11 to form the housing structure of the charging head part of the mobile phone charger. Then, the circuit structure of the mobile phone charger is set inside the housing structure. The circuit structure is conventional prior art, so it will not be described in detail or shown in the accompanying drawings.

[0049] As an optional implementation, it also includes a spring sheet 4, the number of which is two, corresponding to the number of insert body 22. One end of the spring sheet 4 forms a straight connecting section, and the other end forms an elastically raised contact end.

[0050] The straight connecting section on the spring piece 4 connects the top cover 11 and the fixing plate 12, and the two spring pieces 4 correspond to the two insert bodies 22 respectively.

[0051] The contact end of the elastically raised spring 4 is located below the end where the insert body 22 is connected to the rotating member 21. When the insert body 22 is rotated and unfolded to a vertical position under the drive of the auxiliary opening component 3, it can form a squeezing contact with the contact end of the spring 4. At the same time, the spring 4 can maintain and limit the state of the insert body 22, so that it can remain in the unfolded state when it is not subjected to an external force that would allow it to be retracted into the receiving space.

[0052] In this embodiment, the spring 4 is connected to the circuit structure mentioned above, thereby enabling the circuit connection between the insert body 22, the spring 4 and the circuit structure.

[0053] As an optional implementation, the storage slot 111 includes an end slot 1111 and two side slots 1112 connected to the end slot 1111. The end slot 1111 and the two side slots 1112 have the same depth, forming a U-shaped slot structure that can be matched with a U-shaped auxiliary opening component 3. The end slot 1111 is used to store the end connector 31, and the side slots 1112 are used to store the insert body 22 and the rotating arm 32. The slots and the structures stored inside them are matched in shape to form a good storage effect.

[0054] This invention also provides a mobile phone charger, including the aforementioned AC plug opening structure. By using the aforementioned AC plug opening structure, during the unfolding process of the AC plug, the auxiliary opening component 3 can drive the plug component 2 to unfold. The auxiliary opening component 3 can also be stored separately, without taking up space, and avoids affecting normal use due to its addition. Throughout the process, the user's hand will not touch the hardware of the plug component 2. Compared with the existing method of directly prying and bending the AC plug by hand, it is more user-friendly, especially suitable for female users who wear manicures or have long nails. It is convenient to operate, saves more effort, and avoids situations such as broken manicures and damaged nails, effectively improving the user experience.

[0055] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
