Description

Technical Field

[0001] This invention belongs to the field of power supply devices, specifically relating to a power plug structure and a power supply device. Background Technology

[0002] With the advancement of technology and the improvement of people's living standards, more and more electronic devices have been developed and integrated into all aspects of life, becoming an indispensable part of daily life and work, especially small, portable electronic devices such as mobile phones, smartwatches, and tablets. The size of these electronic devices dictates that their internal power supply can only be a small-capacity battery. Under frequent use, a small-capacity battery simply cannot meet the long battery life requirements of these electronic devices. Therefore, power adapters are often needed to charge these electronic devices at any time.

[0003] Existing power converters have numerous components, high manufacturing costs, and are bulky and inconvenient to carry. For example, a power adapter typically includes the adapter body, a power plug, and a power output port. While the power plug is mostly fixed to the adapter body, its protrusion poses a safety hazard when not in use. Furthermore, the protruding plug detracts from the overall aesthetics of the product. In addition, existing power connectors can experience loosening of the plug and socket after repeated plugging and unplugging, leading to poor electrical contact and raising safety concerns. Summary of the Invention

[0004] The purpose of this invention is to provide a power plug structure and power device that can hide the power plug when it is not in use, avoiding safety hazards and other unsafe factors caused by exposed power plugs, while reducing the size of the power device for easy storage and carrying.

[0005] To achieve the above objectives, the present invention provides a power plug structure, which includes a fixed base and a plurality of plugs disposed on the fixed base. Each plug includes a plug circuit end and a plug mains power end.

[0011] Optionally, the plurality of meshing teeth on the protrusion form a meshing area, and the protrusion is provided with a first limiting structure and a second limiting structure. The first limiting structure is disposed at one end of the meshing area along the meshing direction and is used to limit the plug to the open position. The second limiting structure is disposed at the other end of the meshing area along the meshing direction and is used to limit the plug to the closed position.

[0012] Optionally, the first limiting structure is an interference fit connection structure, and / or the second limiting structure is an interference fit connection structure.

[0013] Optionally, the mounting base is provided with a self-rotating connection portion, which allows the mounting base to rotate about an axis at the self-rotating connection portion, so that by rotating the mounting base, the plug can be hidden or exposed to a receiving space.

[0014] Optionally, the self-rotating connection part is a socket or a shaft.

[0015] Optionally, the fixed base is further provided with a self-rotating limiting structure, which is used to lock the position of the fixed base when it rotates, and the self-rotating limiting structure can also release the lock on the fixed base after being subjected to force.

[0019] Optionally, the operating position is a finger hole, and / or the avoidance structure is a chamfered surface.

[0020] Optionally, the power plug structure has at least one of the following features:

[0021] The plug is rotatably connected to the fixed base so that by rotating the entire plug, the plug can be switched between the open position and the closed position.

[0022] The mains power terminal and the circuit terminal of the plug are integrally formed from copper material.

[0023] At least one of the plug's mains terminal and the plug's circuit terminal has a coating on its surface to prevent oxidation.

[0024] The mounting base is made of thermoplastic polymer.

[0025] To achieve the above objectives, the present invention also provides a power supply device, which includes a power supply body and a power plug structure as described in any one of the claims. The power supply body has a receiving space, the power plug structure is disposed in the receiving space, and the fixing base is rotatably connected to the power supply body so that by rotating the fixing base, the plug can be hidden or exposed in the receiving space.

[0026] Optionally, the power supply body includes a housing, and the receiving space is disposed on the outer side of the housing.

[0027] Optionally, the power supply body further includes a conductive spring disposed within the housing, the conductive spring selectively conducting with the plug circuit terminals; in the closed position, the conductive spring does not contact any of the plug circuit terminals, and in the open position, the conductive spring contacts all of the plug circuit terminals.

[0028] Optionally, the housing includes a front shell, a middle frame, and a rear shell that are detachably connected in sequence, and the accommodating space is located on the outer side of the middle frame.

[0029] Optionally, the fixed base is provided with a self-rotating connecting part, the front shell is provided with a front connecting structure, and the rear shell is provided with a rear connecting structure. One end of the self-rotating connecting part is rotatably connected to the front connecting structure, and the other end is rotatably connected to the rear connecting structure. The fixed base is used to rotate about the axis at the self-rotating connecting part.

[0030] Optionally, the housing is provided with a closed limiting structure and an open limiting structure, and the fixed base is provided with a self-rotating limiting structure. The self-rotating limiting structure is used to selectively connect with one of the closed limiting structure and the open limiting structure. When the self-rotating limiting structure is connected with the closed limiting structure, the fixed base is locked, and the power plug structure is completely hidden in the receiving space. When the self-rotating limiting structure is connected with the open limiting structure, the fixed base is locked, and all the plug's mains terminals are exposed outside the receiving space.

[0031] Optionally, the bottom wall of the accommodating space is provided with a through arc-shaped guide groove, and the arc-shaped guide groove is provided one-to-one with the plug circuit end. Each plug circuit end passes through the arc-shaped guide groove and is used to slide along the arc-shaped guide groove.

[0032] In the technical solution provided by the present invention, the power supply device includes a power supply body and a power plug structure. The power plug structure is disposed in the receiving space of the power supply body, and the power plug structure includes a fixing base and a plurality of plugs disposed on the fixing base. Each plug includes a plug circuit end and a plug mains power end. The plug circuit end passes through the fixing base, and the plug mains power end is exposed outside the fixing base and rotatably connected to the fixing base, so that by rotating the plug mains power end, the plug can be switched between an open position and a closed position. In addition, the fixing base is rotatably connected to the power supply body, so that by rotating the fixing base, the plug can be hidden or exposed in the receiving space.

[0033] In this way, when the power supply is not in use, the power plug can be completely hidden within the housing of the power supply body. When the power supply is needed, the plug can be exposed for easy connection to a power outlet. This avoids the safety hazards caused by exposed plugs (i.e., prongs) when the power supply is not in use, reducing the risk of accidents when the power supply is not in use. It also avoids problems such as rusting, storage inconvenience, and difficulty in carrying the plug. Furthermore, the opening and closing of the power plug is achieved by rotating the base and the plug itself. This design is simple and easy to operate, especially saving space by avoiding increasing the size of the power supply, ensuring its storage and portability, and making the overall design more aesthetically pleasing.

Detailed Implementation

[0049] To make the objectives, advantages, and features of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and are not drawn to scale, and are only used to facilitate and clarify the explanation of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structures. In particular, different figures may emphasize different aspects and may sometimes use different scales.

[0050] As used in this invention, the singular forms “a,” “an,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the term “at least two” is generally used to mean “two or more”. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with “first” or “second” may explicitly or implicitly include one or at least two of that feature. “One end” and “the other end” generally refer to two corresponding parts, including not only endpoints. The terms “installed,” “connected,” and “joined” should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two elements or an interaction between two elements. Furthermore, as used in this invention, the phrase "one element is disposed on another element" generally only indicates that there is a connection, coupling, cooperation, or transmission relationship between the two elements, and the connection, coupling, cooperation, or transmission between the two elements can be direct or indirect through an intermediate element. It should not be construed as indicating or implying a spatial positional relationship between the two elements, i.e., one element can be located arbitrarily inside, outside, above, below, or to one side of the other element, unless otherwise explicitly stated. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] In this application, "circumferential" generally refers to the direction around the axis; "axial" generally refers to the direction along the axis; and "radial" generally refers to the diametrical direction, that is, the direction perpendicular to the axis.

[0052] The core idea of ​​this invention is to provide a power plug structure and power supply device to solve the problem that the power plug of existing power adapters protrudes when not in use.

[0053] The following description refers to the accompanying drawings, and the embodiments and features described herein may complement or combine with each other unless otherwise specified.

[0054] like Figures 1 to 4 As shown, this embodiment provides a power supply device 1, which includes a power supply body and a power plug structure 100. The power supply body has a receiving space 4, and the power plug structure 100 is disposed in the receiving space 4.

[0055] like Figures 5 to 7As shown, the power plug structure 100 provided in this embodiment includes a fixing base 130 and a plurality of plugs disposed on the fixing base 130. The plugs are electrical contacts. Typically, two plugs are sufficient, but cases with more than two plugs are also within the scope of this invention. The following description uses two plugs as an illustration, but those skilled in the art should be able to modify the following description to apply to cases with more plugs.

[0056] The two plugs are a first plug 110 and a second plug 120. Each plug includes a mains power terminal 111 and a circuit terminal 114. Each circuit terminal 114 passes through and is connected to a mounting base 130. Each mains power terminal 111 protrudes from and is rotatably connected to the mounting base 130, allowing the plug to be switched between an open and closed position by rotating the mains power terminal 111. The mains power terminal 111 is used for plugging into a power outlet.

[0057] In some embodiments, only the mains terminal 111 of the plug is rotatably connected to the mounting base 130, while the circuit terminal 114 of the plug is fixed and does not rotate. In this case, the plug is opened and closed only by rotating the mains terminal 111. In other embodiments, the entire plug is rotatably connected to the mounting base 130 so that the plug can be switched between open and closed by rotating the entire plug. Compared to rotating only the mains terminal 111, the plug is stronger when the entire plug can rotate. Therefore, in this embodiment, the entire plug is illustrated as being able to rotate relative to the mounting base 130.

[0058] Furthermore, the mounting base 130 is rotatably connected to the power supply body so that by rotating the mounting base 130, all plugs can be hidden or exposed in the receiving space 4. When the mounting base 130 is rotated away from the power supply body (i.e., to the outside of the power supply body), all plugs can be exposed; while when the mounting base 130 is rotated towards the power supply body (i.e., to the inside of the power supply body), all plugs can be hidden.

[0059] Specifically, the plug has an open position and a closed position, and can switch between the open and closed positions. In the closed position, all plug power terminals 111 are preferably arranged side-by-side, more preferably side-by-side and close together. This arrangement facilitates storage and significantly reduces the storage size. In the open position, all plug power terminals 111 are arranged in rows with spacing between them, thus separating the plugs and facilitating connection to the power socket. It should be understood that the open position corresponds to the state when the power device 1 is in use, and the closed position corresponds to the state when the power device 1 is idle and not in use. It should also be understood that the spacing between the power terminals 111 of each plug meets national standards.

[0060] In existing technologies, even if some power supply devices have a function to store the power plug, most of them involve making the entire power plug slide, using the sliding of the entire power plug for storage and opening. This method requires a large space to be reserved on the power supply device for sliding, making the overall size of the power supply device larger, inconvenient for storage and carrying, and requiring additional sliding grooves on the power supply device, affecting the aesthetics of the device. In this invention, however, the power plug structure 100 can be opened and stored simply by rotating the fixing base 130. In this process, only opening and storing the plug is required, making the structure simple and easy to operate. In particular, the storage problem is solved by rotating both the fixing base 130 and the plug, maximizing the saving of internal space in the device, so that the size of the power supply device 1 is not too large, making it easy to store, use and carry. At the same time, the overall appearance of the power supply device 1 is more aesthetically pleasing. Therefore, while ensuring that the power supply device 1 has a storage function, the size and overall aesthetics of the power supply device 1 are also taken into account.

[0061] To address the problem of poor contact between the plug and socket and electrical components, in one embodiment, the power plug structure 100 further includes an elastomer 140 (see [link to embodiment]). Figure 7 The fixing base 130 is elastically connected to the plug circuit end 114 via an elastic body 140. The elastic body 140 compensates for displacement in the axial direction of the plug and limits its movement in the axial direction. The elastic body 140 reduces the risk of the plug becoming loose or detached, ensuring not only the reliability and stability of the electrical connection between the plug and the power circuit, but also the reliability and stability of the connection between the plug and the power socket. The elastic body 140 can be various metal elastic structures, such as springs or retaining rings; in this embodiment, a retaining ring is used for illustration. The elastic body 140 provides a certain holding force during repeated plugging and unplugging or repeated rotation of the plug, ensuring reliable contact between the plug and the power circuit and power socket, thus guaranteeing the reliability and stability of the electrical connection.

[0062] like Figure 7 As shown, in this embodiment, the mounting base 130 has a through mounting hole 134. Each plug circuit end 114 passes through a corresponding mounting hole 134. The radial dimension (including diameter) of the elastic body 140 is larger than the diameter of the mounting hole 134, and the elastic body 140 is positioned on the side of the mounting hole 134 away from the plug mains end 111, and is arranged circumferentially around the plug circuit end 114 along the mounting hole 134. Since the radial dimension of the elastic body 140 is larger than the diameter of the mounting hole 134, the elastic body 140 can prevent the corresponding plug from coming out of the mounting hole 134 in the direction closer to the plug mains end 111, while also achieving displacement compensation in the axial direction of the mounting hole 134.

[0063] The elastomer 140 can be a closed ring structure or a non-closed arc structure. In one embodiment, the elastomer 140 protrudes outside the mounting base 130 and connects to the portion of the plug circuit end 114 protruding outside the mounting base 130. An annular groove 113 is provided on the outer peripheral surface of the portion of the plug circuit end 114 protruding outside the mounting base 130, and the elastomer 140 engages with the annular groove 113 to achieve connection. It should also be understood that the elastomer 140 allows the plug to rotate relative to the mounting hole 134 and provides axial displacement compensation within the mounting hole 134 to ensure reliable electrical connection. The number of elastomers 140 can be one or more. When there are multiple elastomers 140, they are arranged at intervals along the axial direction of the plug circuit end 114. Generally, one elastomer 140 is sufficient. The material of the elastomer 140 has no special requirements, but a high-strength, wear-resistant, and elastic metallic material, such as stainless steel, is preferred.

[0064] In one embodiment, the power supply body includes a housing and electrical components disposed within the housing. This application does not specify the type of electrical components; those skilled in the art should understand the structure of the electrical components based on existing technology. The electrical components may employ a conventional power rectifier and its associated control circuitry (which may be in the form of a circuit board), with the power plug structure 100 connected to the electrical components. The control circuitry may include a power supply circuit for regulating the input voltage and / or a power supply circuit for regulating the output voltage, with the power plug structure 100 electrically connected to the power supply circuitry. Figure 4 As shown, the electrical components may also include a rechargeable battery 50 and a charging coil 60. The charging coil 60 is used to achieve wireless charging and stores electrical energy through the rechargeable battery 50. In this case, the power supply device 1 can be used as a wireless charger (such as a power bank or portable charger). In other embodiments, the power supply device 1 does not include a rechargeable battery 50 and a charging coil 60.

[0065] The connection between the power plug structure 100 and the electrical components can be in various ways, such as being connected to the electrical components via a conductive metal sheet or wire.

[0066] like Figure 10As shown, in one embodiment, all plug circuit terminals 114 are electrically connected to the electrical component via conductive springs 40. The conductive springs 40 are disposed within the housing and directly contact the plug circuit terminals 114 for conduction. Preferably, the conductive springs 40 and plug circuit terminals 114 are selectively connected. Specifically, in the closed position, the conductive springs 40 do not contact the plug circuit terminals 114, further ensuring safety when not in use. In the open position, the conductive springs 40 contact the plug circuit terminals 114 for conduction. It should be noted that the non-contact between the conductive springs 40 and plug circuit terminals 114 when the power plug structure 100 is not in use is not a necessary condition. In other embodiments, the conductive springs 40 may also contact the plug circuit terminals 114 when the power plug structure 100 is not in use. In a specific embodiment, the electrical component includes a circuit board, and the conductive springs 40 are directly soldered onto the circuit board. The circuit board can be used to adjust the input or output voltage to meet different usage requirements.

[0067] Return to reference Figures 1 to 4 Preferably, the receiving space 4 is disposed on the outer side of the housing. Further, the housing may include a front shell 10, a middle frame 20, and a rear shell 30 that are detachably connected in sequence, with the receiving space 4 disposed on the outer side of the middle frame 20. Figure 3 In other embodiments, the housing may be formed by assembling only two shells, i.e., any two of the front shell 10, the middle frame 20, and the rear shell 30, which is also within the scope of protection of this invention.

[0068] Furthermore, the fixing base 130 is rotatably connected to the housing, and the rotatable connection between the two is a shaft-hole fit. In one embodiment, the fixing base 130 is provided with a self-rotating connecting part 131 (see...). Figure 7 and Figure 9 The self-rotating connecting part 131 is rotatably connected to the housing, allowing the fixed base 130 to rotate about the axis at the self-rotating connecting part 131. The self-rotating connecting part 131 can be a socket or a shaft; in this embodiment, a socket is used for illustration.

[0069] Figure 2 and Figure 4In one embodiment shown, the front shell 10 is provided with a front connecting structure 11, and the rear shell 30 is provided with a rear connecting structure 31. One end of the self-rotating connecting part 131 is rotatably connected to the front connecting structure 11, and the other end is rotatably connected to the rear connecting structure 31. One of the self-rotating connecting part 131 and the front connecting structure 11 is a socket, and the other is a shaft inserted into the socket; similarly, one of the self-rotating connecting part 131 and the rear connecting structure 31 is a socket, and the other is a shaft inserted into the cavity. In this embodiment, the self-rotating connecting part 131 is a socket, and both the front connecting structure 11 and the rear connecting structure 31 are shafts. In order not to affect the overall aesthetics of the power supply device 1, both the front connecting structure 11 and the rear connecting structure 31 protrude inward to form shafts.

[0070] To determine the open and closed positions of the fixed base 130 during rotation, in one embodiment, the fixed base 130 is further provided with a self-rotation limiting structure 132 (see...). Figure 7 The self-rotating limiting structure 132 can lock the position of the fixed base 130 during rotation, ensuring that the fixed base 130 is locked in both the open and closed positions of the plug. The self-rotating limiting structure 132 can also release the lock on the fixed base 130 under pressure. The self-rotating limiting structure 132 prevents the fixed base 130 from disengaging from the open and closed positions. Of course, when the fixed base 130 is subjected to a sufficiently large external force, the self-rotating limiting structure 132 can release its lock and allow rotation. The self-rotating limiting structure 132 can be implemented in various ways; a simple rotating limiting protrusion or rotating limiting recess is recommended. However, the rotating limiting protrusion and rotating limiting recess can be provided individually or in combination. Furthermore, the self-rotating limiting structure 132 can be an elastic or non-elastic structure; if it is an elastic structure, the self-rotating limiting structure 132 can achieve limiting using its own elasticity, and the limiting can be released after overcoming the elastic force. The self-rotating limiting structure 132 cooperates with the closed limiting structure and the open limiting structure on the housing to limit the position of the fixed seat 130 when it rotates.

[0071] exist Figure 7 In the exemplary embodiment shown, the self-rotating limiting structure 132 includes a rotation limiting protrusion, such as a hemispherical rotation limiting protrusion formed directly on the surface of the fixing base 130. In other embodiments, the self-rotating limiting structure 132 may be formed in the form of a rolling spring.

[0072] In one embodiment, the housing is provided with a closed limiting structure and an open limiting structure, and a self-rotating limiting structure 132 is used to selectively connect with one of the closed limiting structure and the open limiting structure. When the self-rotating limiting structure 132 is connected with the closed limiting structure, the fixing seat 130 is locked, and the power plug structure 100 is completely hidden in the receiving space 4. When the self-rotating limiting structure 132 is connected with the open limiting structure, the fixing seat 130 is also locked, and all the plug's mains terminals 111 are exposed outside the receiving space 4. Therefore, by utilizing the cooperation of the closed limiting structure and the self-rotating limiting structure 132, the fixing seat 130 can be locked in the closed position of the plug, and by utilizing the cooperation of the open limiting structure and the self-rotating limiting structure 132, the fixing seat 130 can be locked in the open position of the plug.

[0073] like Figure 2 As shown, in one specific embodiment, the front shell 10 is provided with a front closing limiting structure 12 and a front opening limiting structure 13. Figure 4 As shown, in one specific embodiment, the rear shell 30 is provided with a rear closing limiting structure 32 and a rear opening limiting structure 33. When the fixing seat 130 rotates to the point where the self-rotating limiting structure 132 connects with the front closing limiting structure 12 and the rear closing limiting structure 32, the fixing seat 130 is limited to the closed position of the plug; when the fixing seat 130 rotates to the point where the self-rotating limiting structure 132 connects with the front opening limiting structure 13 and the rear opening limiting structure 33, the fixing seat 130 is limited to the open position of the plug.

[0074] In this embodiment, the front closing limiting structure 12, the front opening limiting structure 13, the rear closing limiting structure 32, and the rear opening limiting structure 33 are all rotation limiting recesses that cooperate with the rotation limiting protrusions on the fixed base 130. Furthermore, both the front shell 10 and the rear shell 30 are provided with arc-shaped sliding grooves A (see...). Figure 2 and Figure 4 The front closing limiting structure 12 and the front opening limiting structure 13 are disposed at both ends of the arc-shaped slide groove A of the front shell 10, and the rear closing limiting structure 32 and the rear opening limiting structure 33 are disposed at both ends of the arc-shaped slide groove A of the rear shell 30. The self-rotating limiting structure 132 is a rotating limiting protrusion, which slides in the arc-shaped slide groove A. The two can be in sliding contact or rolling contact, preferably rolling contact to reduce friction and wear.

[0075] like Figure 5 and Figure 6As shown, each plug also includes an insulating element. A portion of the plug's mains terminal 111 is enclosed by the insulating element. The insulating element is made of a polymer material with excellent insulation properties, high mechanical strength, good weather resistance, and flame retardancy, ensuring the safety performance of the power plug structure 100. The first plug 110 includes a first insulating element 112, and the second plug 120 includes a second insulating element 122. Further, each insulating element has a protrusion 116 protruding outward from the side of the insulating element. The protrusion 116 has multiple meshing teeth distributed along its circumference, which are used to connect all the plug's mains terminals 111 through meshing, so that rotating at least one plug's mains terminal 111 causes all plug's mains terminals 111 to rotate synchronously. That is, all plugs can be opened and closed by simply moving one plug with one hand, making operation simple and convenient. Furthermore, it facilitates locking the plugs through meshing, simplifying the structure. The circumference of the protrusion 116 corresponds to the circumference of the plug. The plug terminals 111 rotate synchronously through lateral meshing teeth. Specifically, the protrusion 116 on the first insulating member 112 engages with the protrusion 116 on the second insulating member 122, so that when one plug is turned, the other plug can be rotated together.

[0076] The plurality of meshing teeth on each protrusion 118 form a meshing area. To lock the plug in the open and closed positions, in one embodiment, the protrusion 116 is provided with a first limiting structure and a second limiting structure; the first limiting structure is disposed at one end of the meshing area along the meshing direction and is used to limit the plug in the open position, and the second limiting structure is disposed at the other end of the meshing area along the meshing direction and is used to limit the plug in the closed position. Here, the meshing direction is the rotation direction of the plug's mains terminal 111, that is, the direction around the plug's axis.

[0077] Furthermore, such as Figure 5 As shown, the second limiting structure is an interference fit connection structure 115. Further, as... Figure 6 As shown, the first limiting structure is an interference fit connection structure 125. Through the interference fit connection structures 115 and 125 on the protrusion 116, the power plug structure 100 can be fixed when open and closed, ensuring that the two plugs will not rotate during insertion into the socket and after being closed. The interference fit connection structures 115 and 125 can be understood as follows: the meshing teeth at both ends of the meshing area of ​​the protrusion 116 are interference fit connected. For example, the meshing teeth at one end of the protrusion 116 of the first plug 110 are interference fit connected to the corresponding meshing teeth at the other end of the protrusion 116 of the second plug 120, thereby achieving the effect of preventing rotation.

[0078] like Figure 3As shown, in one embodiment, a through arc-shaped guide groove 21 is provided on the bottom wall of the receiving space 4. The arc-shaped guide groove 21 is provided one-to-one with the plug circuit end 114, and each plug circuit end 114 passes through the arc-shaped guide groove 21 and is used to slide along the arc-shaped guide groove 21. Furthermore, a conductive spring 40 is provided at the position corresponding to the arc-shaped guide groove 21. The conductive spring 40 can be fixed to the middle frame 20 in various ways, including but not limited to snapping the conductive spring 40 onto the middle frame 20. For example... Figure 10 As shown, in this embodiment, the conductive spring 40 is first inserted into the fixing groove of the middle frame 20, and then the conductive spring 40 is soldered to the circuit board. When the power plug structure 100 is rotated to the point where the self-rotation limiting structure 132 is connected to the opening limiting structure (such as the rotation limiting recess), the plug circuit end 114 can be electrically connected to the conductive spring 40.

[0079] like Figure 8a As shown, in one embodiment, the fixing base 130 is further provided with an operating position 133 to facilitate the movement of the fixing base 130 by an external object. The external object can be a human hand or a device. Preferably, the operating position 133 is located on the side of the fixing base 130 corresponding to the mains power terminal 111 of the plug. Further, the first plug 110 has a clearance structure corresponding to the operating position 133, and / or the second plug 120 has a clearance structure corresponding to the operating position 133. The clearance structure is used to prevent the plug from interfering with the external object, so that the external object can smoothly enter and exit between the fixing base 130 and the mains power terminal 111 of the plug. Figure 7 As shown, the clearance structure can be a chamfered surface 117, which is located at the position of the plug mains terminal 111 corresponding to the operating position 133. The operating position 133 can be a finger hole for accommodating a finger, and can be a through hole or a slot. The chamfered surface 117 should be understood as the insulating member forming a concave surface near its bottom surface on the side of the portion covering the plug mains terminal 111.

[0080] Preferably, the plug's mains terminal 111 and circuit terminal 114 are integrally formed from a copper material with high conductivity and wear resistance, such as through integral forging, ensuring sufficient strength of the plug and preventing deformation and breakage. Furthermore, the surfaces of the plug's mains terminal 111 and / or circuit terminal 114 are coated to prevent oxidation, such as through chrome plating, to eliminate contact resistance and minimize heat generation during use. The fixing base 130 is preferably made of a thermoplastic polymer with high fatigue strength and good self-lubricating properties, such as polyethylene, polypropylene, or polyamide, ensuring the service life of the power plug structure 100. The conductive spring 40 is made of a metal material with high fatigue strength and good wear resistance, including but not limited to chromium-zirconium-copper, ensuring reliable electrical connection.

[0081] Next, combine Figures 8a-8b as well as Figures 9 to 12 Furthermore, the usage of the power supply device 1 provided in this embodiment will be further explained through preferred embodiments.

[0082] like Figure 9 As shown, when the power supply unit 1 is not in use, the power plug structure 100 is completely hidden on the side of the power supply body. At this time, the two plugs are side by side and abut against the outer side of the middle frame 20. When the power supply unit 1 needs to be used, refer to... Figure 9 The arrow in the diagram indicates that the fixing seat 130 can be manually or manually moved. After the fixing seat 130 is moved and rotated, the two plugs protrude and are in position. Figure 10 The first open position is shown. After the plugs are exposed, separate the two side-by-side plugs. At this point, you can proceed as follows: Figure 11 The arrow in the diagram rotates the two plugs to separate them, thus switching to... Figure 12 The second open position is shown. Once in the second open position, both plugs can be inserted into the power outlet for use. More details are as follows... Figure 8a As shown, when the two plugs are not separated, they are placed side by side and cannot be rotated inwards; they can only be rotated outwards. (Refer to...) Figure 8a Rotate the plug in the direction indicated by the middle arrow until both plugs are rotated to the open position. They will then be locked by the interference fit connection structure 125 of the first limiting structure, achieving [the desired effect]. Figure 8b The second open position is shown. Conversely, the closing process of the power plug structure 100 is the opposite of the opening process. First, the plug needs to be rotated to close the separated plugs and bring them together. Then, the fixing base 130 is rotated to completely store the entire power plug structure 100 into the receiving space 4.

[0083] In one exemplary embodiment, the assembly process of the power plug structure 100 may be as follows: First, insert all the plug circuit ends 114 of the power plug structure 100 into the arc-shaped guide grooves 21 on the middle frame 20. Then, rotate the power plug structure 100 until all the plug mains terminals 111 are in contact with the middle frame 20. Next, fix the front shell 10 to the middle frame 20 (e.g., with a snap fastener). At this time, the insertion shaft (front connecting structure 11) on the front shell 10 is inserted into the insertion hole (self-rotating connecting part 131) on the fixing base 130. Then, fix the rear shell 30 to the middle frame 20 (e.g., with a snap fastener). At this time, the insertion shaft (rear connecting part 131) on the rear shell 30 is inserted into the insertion hole (self-rotating connecting part 131) on the fixing base 130. The connecting structure 31 is inserted into the socket on the fixing base 130, thus completing the rotatable connection between the fixing base 130 and the housing. After that, by using the cooperation of the self-rotation limiting structure 132 on the fixing base 130 with the front closing limiting structure 12 on the front housing 10 and the rear closing limiting structure 32 on the rear housing 30, the rotation limiting of the power plug structure 100 when closed can be realized. And by using the cooperation of the self-rotation limiting structure 132 on the fixing base 130 with the front opening limiting structure 13 on the front housing 10 and the rear opening limiting structure 33 on the rear housing 30, the rotation limiting of the power plug structure 100 when open can be realized.

[0084] Furthermore, such as Figure 1 As shown, the power supply device 1 may also include a power indicator light 2 and a switch button 3. The power indicator light 2 may have multiple colors, displaying different colors according to the charge level of the rechargeable battery 50, making it easy for the user to determine the battery's charge level. The switch button 3 controls the on / off state of the power supply device 1; it may be a touch button or a non-touch button.

[0085] Finally, it should be noted that although the above embodiments use a wireless charger as an example, the power supply device 1 provided in this embodiment is not limited to a wireless charger. Furthermore, the meshing gear transmission used in the above embodiments to achieve rotation between the plugs is only one implementation method and should not be construed as limiting the invention. Those skilled in the art should understand that many other methods can be used to achieve the rotation and limiting of the plugs. The purpose of using meshing gears is to achieve a linkage effect and avoid operating each plug individually. However, in other implementation methods, each plug can also rotate individually, such as by simultaneously using both hands to rotate each plug. Rotation to the open or closed position is sufficient to lock the plug.

[0086] In summary, the power supply device provided by this invention has a space for accommodating the power plug structure. When the power supply device is not in use, the power plug structure can be completely hidden in the space, while when the power supply device is in use, the plug can be exposed. Therefore, when the power supply device is not in use, it avoids the safety hazards caused by an exposed plug, as well as problems such as rusting, storage inconvenience, and portability. In particular, this invention achieves storage by rotating the fixing base and the plug, maximizing the saving of internal space and preventing the power supply device from becoming too large. Thus, while ensuring the power supply device has a storage function, it also takes into account its size and overall aesthetics. Furthermore, the power plug structure uses an elastic body to connect the fixing base and the plug, reducing the risk of the plug loosening or falling off, thereby ensuring the reliability and stability of the connection between the plug and the socket and electrical components, and further increasing safety.

[0087] It should be noted that those skilled in the art can make various improvements and additions without departing from the method of this invention, and these improvements and additions should also be considered within the scope of protection of this invention. Any modifications, alterations, and variations made by those skilled in the art without departing from the spirit and scope of this invention, based on the disclosed technical content, are equivalent embodiments of this invention; furthermore, any modifications, alterations, and variations made to the above embodiments based on the essential technology of this invention still fall within the scope of the technical solution of this invention.
