Description
Technical Field
[0001] This utility model relates to the field of power converter technology, and in particular to a pin folding and limiting structure for a power converter. Background Technology
[0002] Because plugs and sockets differ from country to country, they are not interchangeable. If you need to insert a plug into an incompatible socket, you will need a power adapter. A power adapter is an conversion tool; to use it, you plug the adapter into the target socket and then insert the target plug into the matching socket on the adapter. Power adapters have greatly improved the convenience of traveling, especially when traveling internationally, eliminating worries about incompatibility between the plugs of your electronic devices and local power outlets.
[0003] Traditional power converters have protruding pins, which take up a lot of space and are easily damaged by external collisions. To address this issue, current products often feature pins that can be flipped up and stored in slots within the power converter housing. However, the pins are frequently not fixed in place after being flipped up, leading to displacement and rotation during use, which is inconvenient for users. Utility Model Content
[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a pin folding and limiting structure for a power converter. This structure can fix the pins after they are flipped over, and provides a tactile feedback when fixing them to indicate that the pins have been flipped into place, which is beneficial for daily use and improves the user experience.
[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:
[0006] A folding and limiting structure for a power converter includes a power converter and a pin assembly rotatably disposed on the power converter. The pin assembly includes a pin housing rotatably disposed on the power converter. The power converter includes a converter housing and a pin storage groove formed on the converter housing and housing the pin assembly therein. The power converter further includes a base disposed within the converter housing. The pin housing is rotatably disposed on the base. Tactile limiting protrusions extending into the power converter are formed on both sides of the pin housing. Tactile limiting grooves for rotating the tactile limiting protrusions are formed on both sides of the base. A tactile limiting protrusion protruding inwardly is symmetrically formed on the inner side of each tactile limiting groove.
[0007] As a further improvement of this utility model, both the upper and lower ends of the tactile limiting protrusion are provided with tactile limiting arc blocks that are integrally arc-shaped and rotate within the tactile limiting groove.
[0008] As a further improvement of this utility model, the upper and lower ends of the tactile limiting protrusion are both arc-shaped, sloping from the lower outer direction to the upper middle, while the middle part is vertically smooth.
[0009] As a further improvement of this utility model, the pin assembly further includes a conductive structure disposed in the pin housing and protruding into the base, and a conductive clearance groove is provided in the middle of the base for the conductive structure to pass through.
[0010] As a further improvement of this utility model, the plug assembly further includes a live wire plug disposed on the plug housing and a neutral wire plug disposed on the plug housing; the conductive structure includes a live wire connecting wire with one end connected to the live wire plug and the other end protruding through the conductive clearance groove, and a neutral wire connecting wire with one end connected to the neutral wire plug and the other end protruding through the conductive clearance groove.
[0011] As a further improvement of this utility model, the power converter also includes a flip-limiting member disposed on the plug storage slot and covering the base. The end of the flip-limiting member facing the plug assembly is generally arc-shaped, and its lower end forms a flip-limiting groove that matches the plug storage slot and allows the plug assembly to rotate. The upper end of the flip-limiting groove is square and matches the plug housing.
[0012] As a further improvement of this utility model, a rotating shaft protruding outward is formed on both sides of the plug housing, and a rotating limiting block protruding towards the flip limiting member is formed on both sides of the base. A first rotating limiting groove matching the rotating shaft is formed at the end of the rotating limiting block facing the flip limiting member. A rotating insertion groove for the rotating limiting block to be inserted is formed on the inner sides of both sides of the flip limiting member. A second rotating limiting groove matching the rotating shaft is formed at the end of the rotating insertion groove away from the base. The rotating shaft rotates in the first rotating limiting groove and the second rotating limiting groove.
[0013] As a further improvement of this utility model, at least one plug storage fixing member is symmetrically arranged on the inner side wall of the plug storage groove, which protrudes inward and presses and limits the plug assembly stored in the plug storage groove.
[0014] The beneficial effects of this utility model are as follows:
[0015] The folding and limiting structure of this plug is configured to include a power converter and a plug assembly rotatably mounted on the power converter. The plug assembly includes a plug housing rotatably mounted on the power converter. The power converter includes a converter housing and a plug storage groove formed on the converter housing to house the plug assembly. The power converter also includes a base disposed within the converter housing. The plug housing is rotatably mounted on the base. Tactile limiting protrusions extending into the power converter are formed on both sides of the plug housing. Tactile limiting grooves for the tactile limiting protrusions to rotate are formed on both sides of the base. A tactile limiting protrusion protruding inwardly is symmetrically formed on the inner side of each tactile limiting groove.
[0016] When users want to store the plug assembly, it can be flipped into the plug storage slot to save space, prevent scratches, and facilitate carrying. When a power adapter is needed, the plug assembly can be flipped out of the slot, allowing the tactile positioning protrusions on the plug housing to slide into the tactile positioning groove between two sets of tactile positioning protrusions. These protrusions hold the plug in place, effectively preventing displacement and malfunction during use. Furthermore, because the tactile positioning protrusions are raised relative to the groove, the different tactile sensation created when the protrusions reach the groove's position provides a distinct tactile feedback, indicating that the plug is properly rotated, thus enhancing the user experience. Furthermore, by setting the tactile limiting groove to limit the flipping stroke of the tactile limiting protrusion, the accuracy of the pin assembly during flipping is effectively prevented, and the pin assembly is prevented from shifting during the flipping process, thus preventing it from becoming unusable.
[0017] The above is an overview of the utility model's technical solution. The following description, in conjunction with the accompanying drawings and specific embodiments, will further illustrate the utility model. Attached Figure Description

Detailed Implementation
[0025] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.
[0026] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0029] Please refer to Figures 1 to 6 This utility model provides a folding and limiting structure for a power converter 1, including a power converter 1 and a plug assembly 2 rotatably disposed on the power converter 1. The plug assembly 2 includes a plug housing 21 rotatably disposed on the power converter 1. The power converter 1 includes a converter housing 11 and a plug storage groove 12 formed on the converter housing 11 and housing the plug assembly 2 therein. The power converter 1 also includes a base 13 disposed within the converter housing 11. The plug housing 21 is rotatably disposed on the base 13. Tactile limiting protrusions 211 extending into the power converter 1 are formed on both sides of the plug housing 21. Tactile limiting grooves 131 for the tactile limiting protrusions 211 to rotate are formed on both sides of the base 13. A tactile limiting protrusion 132 protruding inward is symmetrically formed on the inner side of both sides of the tactile limiting groove 131.
[0030] When people want to store the plug assembly 2, they can flip it over and place it into the plug storage slot 12 to save space occupied by the plug, avoid scratching the plug, and facilitate carrying when traveling. When people need to use the power converter 1, they can flip the plug assembly 2 out of the plug storage slot 12, so that the tactile limiting protrusion 211 on the plug housing 21 slides in the tactile limiting groove 131 between the two sets of tactile limiting protrusions 132 located on the tactile limiting groove 131, and is fixed by the tactile limiting protrusions 132, thereby effectively preventing the plug assembly 2 from shifting during use and causing it to malfunction. Since the tactile limiting protrusion 132 is raised compared to the tactile limiting groove 131, when the tactile limiting protrusion 211 reaches the position of the tactile limiting protrusion 132, it produces a different tactile feel compared to the smooth sidewall of the tactile limiting groove 131. This creates a distinct tactile feedback between the two different feels, providing a unique tactile experience and indicating that the pins have been properly rotated, thus facilitating daily use and improving the user experience. Furthermore, by limiting the rotation stroke of the tactile limiting protrusion 211 through the tactile limiting groove 131, the accuracy of the pin assembly 2 during rotation is effectively prevented, and the pin assembly 2 is prevented from shifting during rotation, thus avoiding problems that could lead to malfunction.
[0031] Preferred, such as Figure 1 and Figure 6 As shown, the plug storage slot 12 is an open slot, and the plug assembly 2 is rotatably disposed in the open slot at the end away from the opening. The plugs in the plug assembly 2 are stored in the opening direction of the open slot, which makes it easier for people to flip the entire plug assembly 2 by using the plugs.
[0032] Preferred, such as Figures 2 to 3 as well as Figure 5 As shown, in order to further limit the tactile limiting protrusion 211, both the upper and lower ends of the tactile limiting protrusion 211 are provided with tactile limiting arc blocks 212 that are arc-shaped and rotate within the tactile limiting groove 131. The arc-shaped structure better matches the curvature of the pin flipping path, so that when the tactile limiting protrusion 211 rotates within the tactile limiting groove 131, it simultaneously drives the tactile limiting arc blocks 212 to rotate within the tactile limiting groove 131. This results in further stroke control by the tactile limiting arc blocks 212 and the tactile limiting groove 131, preventing the tactile limiting protrusion 211 from shifting or falling off during the flipping process. This further improves the flipping accuracy of this pin folding limiting structure and makes it easier for users to operate.
[0033] Regarding the specific structural design of the tactile limiting protrusion 132, as follows: Figures 2 to 3 as well as Figure 5As shown, the upper and lower ends of the tactile limiting protrusion 132 are both arc-shaped, sloping from the lower outer to the upper middle, while the middle part is vertically smooth. When the tactile limiting protrusion 211 is flipped, it receives the inclined guiding effect of the arc-shaped structure, making it easier and more accurate for the tactile limiting protrusion 211 to rotate to the middle of the two sets of tactile limiting protrusions 132 and be clamped and fixed by the two sets of tactile limiting protrusions 132. This effectively prevents the pin assembly 2 from shifting during use and causing it to malfunction, further improving the accuracy of the flipping of this pin folding limiting structure and making it easier for people to use.
[0034] For other structures of the pin assembly 2, such as Figures 2 to 5 As shown, the plug assembly 2 also includes a conductive structure 22 disposed in the plug housing 21 and protruding into the base 13. A conductive clearance groove 133 is provided in the middle of the base 13 for the conductive structure 22 to pass through. By providing a conductive clearance groove 133 in the middle of the base 13, the conductive structure 22 in the plug assembly 2 can pass through the conductive clearance groove 133 to make an electrical connection with the conductive structure 22 in the power converter 1, thereby achieving stable conduction of the plug assembly 2. The conductive structure 22 in the power converter 1 includes a live wire socket conductive clip, a neutral wire socket conductive clip, a ground wire socket conductive clip, etc., which are conventional components in the art, and their structure and principle are existing technology, so they will not be described in detail in this embodiment. Because the base 13 is provided with a through clearance groove 133, the tactile limiting groove 131 has a space for elastic expansion. After the tactile limiting protrusion 211 is placed between the two sets of tactile limiting protrusions 132, the tactile limiting groove 131 elastically deforms outward. After the tactile limiting protrusion 211 rotates away from the tactile limiting protrusion 132, it elastically resets, thereby satisfying the multiple uses of fixing and loosening the tactile limiting protrusion 211 and ensuring the service life of this pin folding limiting structure.
[0035] Regarding the specific conduction method of the pin assembly 2, as follows: Figures 2 to 5 As shown, the plug assembly 2 further includes a live wire plug 23 disposed on the plug housing 21 and a neutral wire plug 24 disposed on the plug housing 21; the conductive structure 22 includes a live wire connecting wire 221 with one end connected to the live wire plug 23 and the other end protruding through the conductive clearance groove 133, and a neutral wire connecting wire 222 with one end connected to the neutral wire plug 24 and the other end protruding through the conductive clearance groove 133. By setting the conductive structure of the live and neutral wires as flexible connecting wires, it better conforms to the path travel required for the plug assembly 2 to be flipped, preventing damage to the rigid connecting structure after multiple flips, further ensuring the service life of this plug folding limiting structure, and facilitating user operation.
[0036] Preferably, the plug assembly 2 further includes a ground pin 25 disposed on the plug housing 21, and the conductive assembly 22 further includes a ground connecting post 223 with one end connected to the ground pin 25 and the other end protruding through the conductive clearance groove 133. By setting the ground conductive structure 22 as a connecting post, the plug assembly 2 can not only be folded vertically up and down, but also rotate laterally around the ground connecting post 223 as the axis, thereby further improving the practicality of this plug folding and limiting structure, making it applicable to different external sockets, more convenient for users, and improving the user experience.
[0037] Preferred, such as Figures 2 to 4 As shown, a ground wire limiting plate 134 protrudes from the center of the conductive clearance groove 133. A ground wire rotation limiting groove 1341 is provided in the center of the ground wire limiting plate 134 for the ground wire connecting post 223 to rotate. By providing a ground wire rotation limiting groove 1341 on the ground wire limiting plate 134, the rotation stroke of the ground wire connecting post 223 is limited by the ground wire rotation limiting groove 1341 during flipping. This effectively prevents the ground wire connecting post 223 from shifting during flipping, thus preventing it from failing to connect with the conductive structure 22 inside the power converter 1. This further improves the accuracy of the flipping of this pin folding limiting structure, making it easier for users to operate.
[0038] Preferred, such as Figures 1 to 3 as well as Figure 6 As shown, the power converter 1 also includes a flip-up limiting member 14 disposed on the plug storage slot 12 and covering the base 13. The end of the flip-up limiting member 14 facing the plug assembly 2 is generally arc-shaped, and its lower end forms a flip-up limiting groove 141 that matches the plug storage slot 12 and allows the plug assembly 2 to rotate. The upper end of the flip-up limiting groove 141 is square and matches the plug housing 21. The plug housing 21 rotates on the flip-up limiting member 14. By setting the flip-up limiting member 14 to be generally arc-shaped, it is more conducive to the plug assembly 2 to rotate laterally while flipping vertically, thereby further improving the practicality of this plug folding limiting structure. This makes the plug folding limiting structure applicable to different external sockets, which is more convenient for people to use and improves the user experience. By setting the upper end of the flip-limiting groove 141 to be square and matching the pin housing 21, the pin housing 21 is limited, preventing it from flipping further when it is flipped 90 degrees from the pin storage groove 12. This prevents the pin assembly 2 from over-flipping, facilitating its normal operation. In conjunction with the tactile limiting protrusion 132 and the tactile limiting protrusion 211, the pin assembly 2 is fixed, preventing it from shifting during use and causing it to malfunction.
[0039] Regarding the specific method by which the pin assembly 2 is flipped on the flipping limiting member 14, as follows: Figures 1 to 3 As shown, a rotating shaft 213 protruding outward is formed on both sides of the plug housing 21, and a rotating limiting block 135 protruding towards the flip limiting member 14 is formed on both sides of the base 13. A first rotating limiting groove 1351 matching the rotating shaft 213 is formed at one end of the rotating limiting block 135 facing the flip limiting member 14. A rotating insertion groove 142 for the rotating limiting block 135 to be inserted is formed on the inner sides of both sides of the flip limiting member 14. The rotating insertion groove 142 is located away from... One end of the base 13 is formed with a second rotation limiting groove 1421 that matches the rotation shaft 213. The rotation shaft 213 rotates in the first rotation limiting groove 1351 and the second rotation limiting groove 1421. The first rotation limiting groove 1351 and the second rotation limiting groove 1421 limit the rotation shaft 213, thereby allowing the pin housing 21 to flip between the flip limiting member 14 and the base 13, achieving the purpose of storage and extension, and ensuring the normal operation of this pin folding limiting structure.
[0040] Preferred, such as Figure 1 and Figure 6 As shown, in order to better house the plug assembly 2 in the plug storage slot 12, at least one plug storage fixing member 15 is symmetrically arranged on the inner side wall of the plug storage slot 12. The plug storage fixing member 15 protrudes inward and presses and limits the plug assembly 2 housed in the plug storage slot 12. The plug storage fixing member 15 protrudes towards the middle of the plug storage slot 12. Its protruding position presses against the plug shell 21 housed in the plug storage slot 12 to achieve a fastening, thereby further fixing the plug assembly 2 and preventing the plug assembly 2 from protruding and causing damage to the outside and itself when it is not used, such as when traveling.
[0041] Preferred, such as Figure 1 and Figure 6 As shown, the outer and inner sides of the plug storage fixing member 15 are both inclined, so that the plug assembly 2 is affected by its inclined guiding surface when entering the plug storage slot 12 and flipping out of the plug storage slot 12, making it easier and more accurate to store and flip for use, further improving the user experience of this plug folding limiting structure.
[0042] It should be noted that the folding and limiting structure for the power converter disclosed in this utility model is an improvement on the specific structure, but the specific control method is not an innovation of this utility model. The live wire pin, neutral wire pin, ground wire pin, flexible connecting wire, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.
[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
