Description

Technical Field

[0001] This disclosure relates to the field of plug technology, and more particularly to a foldable plug and charger. Background Technology

[0002] As consumers increasingly demand portability of their devices, some chargers are being designed to be foldable.

[0003] In the related technologies, the plug of the charger has low impact resistance when unfolded and is easily damaged when dropped, resulting in poor practicality. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this disclosure provides a foldable plug and charger.

[0005] According to a first aspect of this disclosure, a folding plug is provided, comprising:

[0006] Base;

[0007] A latch assembly includes two latches and an insulating element disposed between the two latches;

[0008] The pin includes a pin body and a mounting structure protruding from the side wall of the pin body. The pin body is movably connected to the base through the mounting structure, so that the pin assembly can be flipped relative to the base to switch the foldable plug between an unfolded state and a retracted state.

[0009] The insulating component does not come into contact with the base when the foldable plug is in the unfolded state.

[0010] In some embodiments, along the arrangement direction of the two pins, the mounting structure is disposed on the side of the pin body facing the insulating member; and / or,

[0011] The mounting structure is located on the side of the pin body opposite to the insulating component.

[0012] In some embodiments, the mounting structure is provided on both the side of the pin body facing the insulating member and the side of the pin body facing away from the insulating member, and the two mounting structures provided on the same pin body have the same shape.

[0013] In some embodiments, the pin body and the mounting structure are integrally formed.

[0014] In some embodiments, the base includes a first bearing and a second bearing, one of the two pins is movably connected to the first bearing, and the other is movably connected to the second bearing, and the first bearing and the second bearing are disposed between the two pins;

[0015] Wherein, the distance between the two mounting structures connected to the first bearing and the second bearing is less than or equal to the distance between the first bearing and the second bearing.

[0016] In some embodiments, the radial dimension of the insulating element is less than or equal to the radial dimension of the mounting structure.

[0017] In some embodiments, in the extending direction of the insulating member, a mounting groove is provided on the side of the mounting structure away from the pin body, the mounting groove being formed by a portion of the surface of the mounting structure recessed toward the pin body;

[0018] A portion of the end structure of the insulating component extends into the mounting groove.

[0019] In some embodiments, the pin body has a first limiting protrusion at one end of the mounting structure. The first limiting protrusion is used to contact the base when the foldable plug is in the unfolded state, so as to restrict the pin assembly from flipping in a first direction.

[0020] In some embodiments, a portion of the outer peripheral surface of the insulating member protrudes radially outward to form a second limiting protrusion, the second limiting protrusion being used to contact the base when the folding plug is in a retracted state to restrict the pin assembly from flipping in a second direction;

[0021] The first direction is opposite to the second direction.

[0022] According to a second aspect of this disclosure, a charger is provided, including a folding plug as described in the first aspect.

[0023] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: by setting an installation structure in the pin and setting the insulating part to not contact the base in the unfolded state of the folded plug, when the pin body of the folded plug is subjected to external impact, the impact on the pin body can only be transmitted to the base through the installation structure, so as to avoid damage to the insulating part and improve the impact resistance of the folded plug in the unfolded state.

[0024] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0032] Figure 7 This is a schematic diagram illustrating a latch assembly according to an exemplary embodiment of the present disclosure. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] See Figures 2 to 4 The illustration shows a folding plug in the related art, which includes a base 10' and a pin assembly 20'. The base 10' includes a first housing 10a' and a second housing 10b' that can be snapped together to fix the pin assembly 20'. The pin assembly 20' includes an insulator 22' and two pins 21'. The insulator 22' is used to mount the two pins 21' and is connected to a bearing (such as a first bearing 11' and a third bearing 13') of the base 10' so that the two pins 21' can rotate relative to the base 10'.

[0035] It is certain that when the pin 21' is subjected to an external impact, the impact force on the pin 21' will be directly transmitted to the insulating component 22', resulting in the external impact being entirely borne by the insulating component 22', such as the top surface of the pin 21' ( Figure 1 As shown in the z direction, compression will occur between the insulating part 22' and the top wall of the insulating part 22'. For example, compression will occur between the insulating part 22' and the first shaft seat 11' and the third shaft seat 13'. Due to the insufficient structural strength of the insulating part 22', the folding plug in the related technology is very easy to be damaged and scrapped.

[0036] To address the aforementioned technical problems, this disclosure provides a foldable plug and charger. The foldable plug includes a base and a pin assembly. The pin assembly includes two pins and an insulating member disposed between the two pins. Each pin includes a pin body and a mounting structure protruding from the side wall of the pin body. The pin body is movably connected to the base via the mounting structure. The pin body can rotate relative to the base to switch the foldable plug between an unfolded state and a retracted state. When the foldable plug is in the unfolded state, the insulating member does not contact the base. In this embodiment, by providing a mounting structure in the pins and configuring the insulating member to not contact the base in the unfolded state of the foldable plug, when the pin body of the foldable plug is subjected to external impact, the impact can only be transmitted to the base through the mounting structure, thus avoiding damage to the insulating member and improving the impact resistance of the foldable plug in the unfolded state.

[0037] According to an exemplary embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, this disclosure provides a folding plug, which includes a base 10 and a pin assembly 20, the base 10 being used to mount the pin assembly 20. In one example, see [reference needed]. Figure 1 and Figure 5 The base 10 includes a first housing 10a and a second housing 10b, which can fix the pin assembly 20 when the first housing 10a and the second housing 10b are fastened together.

[0038] like Figure 1 and Figure 6 As shown, the plug assembly 20 can be flipped relative to the base 10 to switch the folding plug between an unfolded state and a retracted state. When the folding plug is in the unfolded state, the pin 21 of the plug assembly 20 protrudes from the surface of the base 10 so that it can be inserted into the electrical interface (socket). When the folding plug is in the retracted state, the plug assembly 20 will be folded and retracted into the base 10 to prevent the pin 21 from making physical contact with the external structure and causing damage.

[0039] See Figures 5 to 7The pin assembly 20 includes two pins 21 and an insulating member 22 disposed between the two pins 21, along the arrangement direction of the two pins 21. Figure 1 (As shown in the x-direction), the two ends of the insulating member 22 are respectively connected to the two pins 21. The insulating member 22 is used to realize the synchronous rotation of the two pins 21 and to insulate the two pins 21 to avoid short circuit. This embodiment does not limit the shape of the pins 21 too much. The pins 21 can be cylindrical pins 21, flat pins 21, etc. The pins 21 can be made of conductive metal materials such as copper, and the insulating member 22 can be made of plastic material.

[0040] See Figure 7 The pin 21 includes a pin body 211 and a mounting structure 212 protruding from the side wall of the pin body 211. The pin body 211 is movably connected to the base 10 through the mounting structure 212. The movable connection can be, for example, a rotatable connection (see [reference]). Figure 6 Alternatively, a sliding connection (not shown in the attached diagram) can be used. It should be noted that a sliding connection can be implemented by setting the mounting structure to be arc-shaped, with an annular groove or an arc-shaped groove on the base that has a central angle greater than the arc angle of the mounting structure. The arc-shaped mounting structure can slide in the annular groove or arc-shaped groove.

[0041] Among them, see Figure 5 The pin 21 of the pin assembly 20 is connected to the base 10 via the mounting structure 212, while the insulating element 22 does not contact the base 10. See one example. Figure 6 The base 10 is internally spaced with a third bearing seat 13, a first bearing seat 11, a second bearing seat 12, and a fourth bearing seat 14. Two pins 21 include a first pin 21a and a second pin 21b21. The pin body 211 of the first pin 21a is located between the third bearing seat 13 and the first bearing seat 11. A mounting structure 212 connected to the pin body 211 of the first pin 21a can be connected to the third bearing seat 13 and / or the first bearing seat 11. The second pin 21b21… The pin body 211 of the first pin 1 is located between the second bearing 12 and the fourth bearing 14. The mounting structure 212 connected to the pin body 211 of the second pin 21b21 can be connected to the second bearing 12 and / or the fourth bearing 14. The insulating member 22 is disposed between the first bearing 11 and the second bearing 12. The insulating member 22 is installed in the base 10 only through the two pins 21, so that it does not come into contact with the first bearing 11, the second bearing 12 or other structures of the base 10.

[0042] Understandably, the pin 21 is typically made of conductive metal, thus possessing high structural strength, while the material of the insulating component 22 has significantly lower structural strength than the pin 21. When the folding plug is in the unfolded state, most of the structure of the pin body 211 is exposed to the environment. External impacts to the pin body 211 transmit the impact force to the mounting structure 212 and then to the base 10. Throughout this force transmission process, the pin 21 extends in the direction of the insulating component 22 (…). Figure 1 The insulation component 22 can generate a very small displacement or no displacement in the x direction shown in the figure. Furthermore, the insulation component 22 can be configured to have a certain gap between it and the pin 21 in the extension direction (detailed in the following text). Thus, the external impact on the pin body 211 will not affect the insulation component 22, thereby effectively avoiding damage to the insulation component 22 and improving the impact resistance of the pin assembly 20 and the folding plug.

[0043] In this embodiment, by providing an installation structure 212 in the pin 21 and setting the insulating part 22 so that it does not contact the base 10 in the unfolded state of the folded plug, when the pin body 211 of the folded plug is subjected to external impact, the impact on the pin body 211 can only be transmitted to the base 10 through the installation structure 212, so as to avoid damage to the insulating part 22 and improve the impact resistance of the folded plug in the unfolded state.

[0044] In one exemplary embodiment, such as Figure 5 and Figure 6 As shown, this embodiment provides a folding plug, which includes a base 10 and a pin assembly 20. The pin assembly 20 includes two pins 21 and an insulating member 22 disposed between the two pin assemblies 20. Each pin 21 includes a pin body 211 and a mounting structure 212 protruding from the side wall of the pin body 211. The pin body 211 is movably connected to the base 10 through the mounting structure 212. The pin body 211 can be flipped relative to the base 10 to switch the folding plug between an unfolded state and a retracted state. When the folding plug is in the unfolded state, the insulating member 22 does not contact the base 10.

[0045] Among them, such as Figure 6 As shown, along the arrangement direction of the two pins 21 ( Figure 1 (as shown in the x direction), at least one of the side of the pin body 211 facing the insulating member 22 and the side of the pin body 211 facing away from the insulating member 22 is provided with a mounting structure 212.

[0046] In some embodiments, see Figure 6 Along the arrangement direction of the pin body 211 ( Figure 1As shown in the x direction, the side of the pin body 211 facing the insulating member 22 and the side facing away from the insulating member 22 are provided with mounting structures 212, so that the two mounting structures 212 can support the pin body 211 at the same time, thereby improving the connection reliability between the pin body 211 and the base 10.

[0047] In one example, see Figure 6 The two mounting structures 212 located on both sides of the same pin body 211 have the same shape, that is, the two pins 21 in the pin assembly 20 have the same shape. This arrangement eliminates the need to distinguish the shape of the pins 21 during assembly, improving assembly efficiency and yield. Furthermore, the two pins 21 required for the folding plug can be produced using only the same mold, reducing mold design costs.

[0048] In other embodiments (not shown in the figures), a mounting structure 212 is provided on one side of the pin body 211. In this embodiment, by appropriately extending the dimension of the mounting structure 212 in the x-direction, a reliable connection between the pin body 211 and the base 10 can also be achieved. In one example, the length of the mounting structure 212 in this embodiment is greater than or equal to the sum of the lengths of the two mounting structures 212 in the aforementioned embodiment (where two mounting structures 212 are provided).

[0049] Among them, such as Figure 7 As shown, the pin body 211 and the mounting structure 212 can be integrally formed. Integral forming processes include die casting, stamping, metal injection molding, and 3D printing. Integral forming processes offer advantages such as short process flow, high consistency, high precision, low cost, and high efficiency. In some optional embodiments, the pin body 211 and the mounting structure 212 can be connected by welding.

[0050] In one exemplary embodiment, such as Figure 5 and Figure 6 As shown, this embodiment provides a folding plug, which includes a base 10 and a pin assembly 20. The pin assembly 20 includes two pins 21 and an insulating member 22 disposed between the two pin assemblies 20. Each pin 21 includes a pin body 211 and a mounting structure 212 protruding from the side wall of the pin body 211. The pin body 211 is movably connected to the base 10 through the mounting structure 212. The pin body 211 can be flipped relative to the base 10 to switch the folding plug between an unfolded state and a retracted state. When the folding plug is in the unfolded state, the insulating member 22 does not contact the base 10.

[0051] The folding plug provided in this embodiment can include any structure and device of the folding plug provided in any of the above embodiments. For example, the pin body 211 and the mounting structure 212 of the pin 21 can be an integrally formed structure.

[0052] Among them, such as Figure 6 As shown, the base 10 includes a first bearing 11 and a second bearing 12, which are disposed between two pins 21. The distance between the two mounting structures 212 located between the two pins 21 is less than or equal to the distance between the first bearing 11 and the second bearing 12, thereby separating the insulating member 22 from the first bearing 11 and the second bearing 12. This prevents the force transmitted from the pin body 211 to the insulating member 22 when it is impacted, thus avoiding the insulating member 22 from being squeezed against the first bearing 11 and the second bearing 12, thereby protecting the insulating member 22. In some embodiments, such as Figure 6 As shown, the radial dimension of the insulating member 22 is set to be less than or equal to the radial dimension of the mounting structure 212. With this setting, regardless of whether the distance between the two mounting structures 212 in the aforementioned embodiment is less than or equal to the distance between the first bearing 11 and the second bearing 12, the insulating member 22 can be prevented from contacting the first bearing 11 and the second bearing 12, so as to effectively protect the insulating member 22 when the pin body 211 is impacted.

[0053] Among them, such as Figure 6 As shown, in the extending direction of the insulating member 22 ( Figure 1 In the x-direction shown, a mounting groove 2121 is provided on the side of the mounting structure 212 away from the pin body 211. The mounting groove 2121 is formed by a portion of the surface of the mounting structure 212 recessed towards the pin body 211, and a portion of the insulating member 22 extends into the mounting groove 2121. In one example, see [reference needed]. Figure 7 The insulating component 22 has a splined shaft for extending into the mounting groove 2121, and there is a certain gap between the splined shaft and the bottom wall of the mounting groove 2121. This arrangement ensures that the two pins 21 rotate synchronously, and when the pin body 211 is subjected to external impact causing the pin 21 to displace in the x-direction, the mounting gap between the splined shaft and the mounting groove 2121 can prevent the pin 21 from directly pressing the insulating component 22, thereby effectively protecting the insulating component 22.

[0054] Among them, such as Figure 7 As shown, one end of the mounting structure 212 of the latch body 211 has a first limiting protrusion 2111. The first limiting protrusion 2111 is used to contact the base 10 when the folding plug is in the unfolded state, so as to limit the latch assembly 20 along the first direction ( Figure 6 The direction shown (a) is flipped. See one example. Figure 6When the pin assembly 20 is in the deployed state, the extension direction of the pin body 211 is perpendicular to the surface of the base 10. In this embodiment, a first limiting protrusion 2111 for limiting the extreme deployed position of the pin 21 is provided on the pin body 211. Both the first limiting protrusion 2111 and the pin body 211 are supported by metal materials, thus having stronger structural strength, thereby improving the impact resistance of the pin 21 in the deployed state. Compared with the related art in which the limiting structure is provided on the insulating member 22, this can effectively protect the insulating member 22 from damage.

[0055] See Figure 7 A portion of the outer peripheral surface of the insulating member 22 protrudes radially outward to form a second limiting protrusion 221. The second limiting protrusion 221 is used to contact the base 10 when the folding plug is in the retracted state to limit the pin assembly 20 along the second direction ( Figure 6 The pin is flipped in direction b, with the first direction being opposite to the second direction. In some optional embodiments (not shown in the figures), a limiting protrusion with the same function as the second limiting protrusion can be provided on the pin body, which will not be described in detail here. In this embodiment, by setting the second limiting protrusion to limit the pin, it is possible to prevent the pin from colliding with the base when it is flipped to the storage position, to avoid damage to the surface of the pin or the base, and to reduce or avoid noise.

[0056] According to an exemplary embodiment of this disclosure, a charger is also provided, which can be used to charge various electrical devices such as smartphones, laptops, tablets, or electric vehicles. The charger is equipped with the foldable plug provided in any of the foregoing embodiments of this disclosure, thus the charger possesses all the technical effects of the foldable plug provided in this disclosure, which will not be elaborated further.

[0057] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0058] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
