Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charger. Background Technology

[0002] A charger is a device used to provide power to various electronic devices (such as mobile phones, tablets, laptops, power tools, etc.). Depending on the application scenario and device requirements, the design and technology of the charger's plug vary. Due to the height requirements of European standard chargers, most European standard chargers on the market are currently quite tall, sometimes even thicker, resulting in large, oddly shaped chargers that are inconvenient to carry. Utility Model Content

[0003] In view of this, embodiments of this application aim to provide a charger that allows the plug assembly to switch between an extended state and a retracted state. When the charger does not need to charge electronic devices, the plug assembly can move to the retracted state, which helps to reduce the size of the charger in the first direction and makes the charger easier to store.

The insulating portion connects the first bending sub-link and the second bending sub-link. The first bending sub-link is electrically connected to a portion of the first conductive shaft, and the second bending sub-link is electrically connected to another portion of the first conductive shaft. The third direction is perpendicular to the first direction and the second direction.

[0016] In some embodiments, the second bending link passes through the hollow region between the first bending sub-rod and the second bending sub-rod, and is rotatably connected to the first bending sub-rod and the second bending sub-rod.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0037] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0038] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0039] Please see Figure 1 , Figure 5 and Figure 7 This application provides a charger, which includes a charging body 10, a plug assembly 20 and a linkage mechanism 30. The plug assembly 20 is connected to the charging body 10 through the linkage mechanism 30. The charging body 10 includes a charging circuit. The plug assembly 20 has multiple pins 21. The linkage mechanism 30 is a conductor and can drive the plug assembly 20 to move between an unfolded state and a retracted state.

[0040] In the unfolded state, the plug assembly 20 and the charging body 10 are arranged along a first direction, and multiple prongs 21 establish a conductive path with the charging circuit through the linkage mechanism 30. The prongs 21 are used to connect to the socket that provides power. In the unfolded state, the prongs 21 are connected to the socket, which enables circuit connection with the socket, facilitating the charger to charge electronic devices.

[0041] In the stowed state, the plug assembly 20 and the charging body 10 are arranged along the second direction, and the first and second directions intersect. At this time, the plug assembly 20 is in a flipped-folded state compared to the unfolded state.

[0042] Please see Figure 1 and Figure 2 The plug assembly 20 and the charging body 10 are arranged along the first direction, meaning that the plug assembly 20 is on the side of the charging body 10 facing the first direction.

[0043] Please see Figure 5 and Figure 6 The plug assembly 20 and the charging body 10 are arranged along the second direction, meaning that the plug assembly 20 is on the side of the charging body 10 facing the second direction.

[0044] That is, the linkage mechanism 30 drives the plug assembly 20 to move, so that the plug assembly 20 can switch between the unfolded state and the retracted state. When the charger does not need to charge the electronic device, the plug assembly 20 can move to the retracted state, which helps to reduce the size of the charger in the first direction, making the charger easier to store.

[0045] In some embodiments, the first direction is substantially perpendicular to the second direction, so that the size of the charger along the second direction is as small as possible when the plug assembly 20 is in the retracted state. "Substantially perpendicular" means that some manufacturing and installation tolerances are permissible.

[0046] For example, the first direction is Figure 1 , Figure 2 , Figure 5 and Figure 6 The direction shown in d1 is the second direction. Figure 1 , Figure 2 , Figure 5 and Figure 6 The direction indicated by d2.

[0047] It should be noted that d1 refers to the direction of the charging body 10 toward the plug assembly 20 in the unfolded state, and the direction of the plug assembly 20 toward the charging body 10 is the opposite of the first direction. d2 refers to the direction of the charging body 10 toward the plug assembly 20 in the retracted state, and the direction of the plug assembly 20 toward the charging body 10 is the opposite of the second direction.

[0048] In some embodiments, the linkage mechanism 30 disconnects the conductive path from the charging circuit in the retracted state. That is, in the retracted state, the plug assembly 20 and the charging body 10 cannot form a conductive path, thereby helping to improve the safety of the charger in the retracted state.

[0049] In some embodiments, please refer to Figure 8 and Figure 9 The charging circuit includes multiple conductive clips 11, and the linkage mechanism 30 includes multiple first conductive shafts 31, which move relative to the charging body 10.

[0050] In the unfolded state, a portion of the first conductive shaft 31 makes conductive contact with a portion of the conductive clip 11 to connect to the positive terminal of the charging circuit, while another portion of the first conductive shaft 31 and the other portion of the conductive clip 11 make conductive contact to connect to the negative terminal of the charging circuit. This allows the pin 21 to establish a conductive path through the first conductive shaft 31 to the charging circuit.

[0051] In the retracted state, the first conductive shaft 31 separates from the conductive clip 11, thereby disconnecting the conductive path between the linkage mechanism 30 and the charging circuit. In other words, in the retracted state, there is no electrical conductivity between the plug 21 and the charging circuit, which helps improve the safety of the charger when retracted.

[0052] In this embodiment, the first conductive shaft 31 and the conductive clamp 11 are detachably connected. The conductive path is connected by the contact between the first conductive shaft 31 and the conductive clamp 11, and the conductive path is disconnected by the separation of the first conductive shaft 31 and the conductive clamp 11.

[0053] It should be noted that the number of conductive clips 11 is at least two, with at least one conductive clip 11 used for conductive connection with the positive terminal of the charging circuit and at least one conductive clip 11 used for conductive connection with the negative terminal of the charging circuit.

[0054] The number of first conductive shafts 31 is at least two. In the unfolded state, at least one first conductive shaft 31 can be conductively connected to the conductive clip 11 that is conductively connected to the positive terminal of the charging circuit, and at least one first conductive shaft 31 can be conductively connected to the conductive clip 11 that is conductively connected to the negative terminal of the charging circuit.

[0055] In some embodiments, please refer to Figure 10 The charging body 10 has a first groove 121 inside, which extends along a first direction. The end of the first conductive shaft 31 extends into the first groove 121 and can move within it. That is, the first conductive shaft 31 moves along the first direction by cooperating with the first groove 121, thereby achieving contact and separation with the conductive clamp 11.

[0056] For example, please refer to Figure 9 The conductive clamp 11 includes at least two spring arms 111 for clamping the first conductive shaft 31. The at least two spring arms 111 enclose a clamping space 1111 and a first opening 1112. The first opening 1112 is used for the first conductive shaft 31 to enter and exit the clamping space 1111.

[0057] In this embodiment, when the first conductive shaft 31 needs to establish a conductive connection with the conductive clamp 11, the first conductive shaft 31 slides in the opposite direction of the first direction, and pushes the two spring arms 111 in the opposite direction of the first direction. The two spring arms 111 separate under the action of the pushing force of the first conductive shaft 31 in the opposite direction of the first direction, so that the first conductive shaft 31 can enter the clamping space 1111 through the first opening 1112. When the first conductive shaft 31 needs to disconnect from the conductive clamp 11, the first conductive shaft 31 slides in the first direction, and the two spring arms 111 separate under the action of the pushing force of the first conductive shaft 31 in the first direction, so that the first conductive shaft 31 can move away from the clamping space 1111 through the first opening 1112.

[0058] That is, the elasticity of the two spring arms 111 is used to achieve a separable connection between the first conductive shaft 31 and the conductive clamp 11. The clamping effect of the two spring arms 111 enables the first conductive shaft 31 to be stably connected to the conductive clamp 11 when it is in the unfolded state, thereby helping to improve the charging stability of the charger.

[0059] In some embodiments, such as Figure 7 As shown, the charging body 10 includes a connecting cover 12 and a housing 13 having a second opening 131. Figure 3 and Figure 4 As shown, the connecting cover 12 is located inside the housing 13 and covers the second opening 131, and the linkage mechanism 30 is connected to the connecting cover 12. The housing 13 is an exterior component of the charging body 10 and can provide protection for other components of the charging body.

[0060] For example, the housing 13 is an insulator.

[0061] In this embodiment, the first groove 121 is provided on the inner wall of the connecting cover 12. (See also...) Figure 10 The inner wall of the connecting cover 12 has two side walls spaced apart along a third direction, each forming a first sliding groove 121, which allows the first conductive shaft 31 to slide.

[0062] The third direction is perpendicular to the first and second directions; for example, the third direction is... Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 10 The direction shown in d3.

[0063] For example, please refer to Figure 8 and Figure 9The linkage mechanism 30 includes a first curved link 33 and a second curved link 34 that are rotatably connected. The first end 33a of the first curved link 33 is rotatably connected to the plug assembly 20, and the second end 33b of the first curved link 33 is slidably connected to the charging body 10. The second end 33b of the first curved link 33 is slidable along a first direction, and the first conductive shaft 31 is disposed at the second end 33b of the first curved link 33.

[0064] The first end 34a of the second curved link 34 is rotatably connected to the charging body 10, and the second end 34b of the second curved link 34 is slidably connected to the plug assembly 20.

[0065] In this embodiment, when the plug assembly 20 needs to switch from the unfolded state to the retracted state, the plug assembly 20 is rotated. The plug assembly 20 rotates within the plane formed by the intersection of the first and second directions. The plug assembly 20 drives the first end 33a of the first curved connecting rod 33 to rotate, causing the second end 33b of the first curved connecting rod 33 to slide along the first direction. During the rotation of the plug assembly 20, the second end 34b of the second curved connecting rod 34 slides away from the plug assembly 20, causing the first end 34a of the second curved connecting rod 34 to rotate within the charging body 10. At the same time, the first curved connecting rod 33 and the second curved connecting rod 34 are rotatably connected, supporting and constraining each other. During the rotation of the plug assembly 20, the charging body 10 remains stationary, and the first end 34a of the second curved connecting rod 34 is rotatably connected to the charging body 10, serving as a positioning and constraint for the entire linkage mechanism 30. The coordinated action of the first bending link 33 and the second bending link 34 enables the plug assembly 20 to move from the side of the charging body 10 facing the first direction to the side of the charging body 10 facing the second direction, that is, the plug assembly 20 is flipped along the edge of the charging body 10.

[0066] It is understandable that the degree of bending of the first bending link 33 and the second bending link 34 can be designed according to the rotation angle and rotation trajectory of the plug assembly 20.

[0067] In some embodiments, please refer to Figure 9 The linkage mechanism 30 includes a rotating shaft 342 connected to the first end 34a of the second curved link 34. Specifically, there are two rotating shafts 342, each protruding from both sides of the first end 34a of the second curved link 34 in a third direction. (See also...) Figure 10 The inner wall of the connecting cover 12 has two side walls that are opposite each other along the third direction, and the rotating shaft 342 passes through the first positioning hole 122 and can rotate around the first positioning hole 122.

[0068] In some embodiments, such as Figure 8 and Figure 9As shown, the first bending connecting rod 33 includes a first bending sub-rod 331, a second bending sub-rod 332, and an insulating part 334. The first bending sub-rod 331 and the second bending sub-rod 332 are both conductors and are arranged at intervals along a third direction. The insulating part 334 connects the first bending sub-rod 331 and the second bending sub-rod 332. The first bending sub-rod 331 is electrically connected to a portion of the first conductive shaft 31, and the second bending sub-rod 332 is electrically connected to another portion of the first conductive shaft 31. The third direction is perpendicular to the first direction and the second direction.

[0069] In this embodiment, the first bent sub-rod 331 is electrically connected to a portion of the first conductive shaft 31, meaning the first bent sub-rod 331 can be electrically connected to the positive terminal of the charging circuit. The second bent sub-rod 332 is electrically connected to another portion of the first conductive shaft 31, meaning the second bent sub-rod 332 can be electrically connected to the negative terminal of the charging circuit. Furthermore, the first bent sub-rod 331 and the second bent sub-rod 332 are spaced apart along a third direction, creating a gap between them. After the pin 21 is connected to the socket, current flows through both the first bent sub-rod 331 and the second bent sub-rod 332. This spacing reduces the mutual interference between the current flowing through the first bent sub-rod 331 and the current flowing through the second bent sub-rod 332. Connecting the first bent sub-rod 331 and the second bent sub-rod 332 via the insulating part 334 helps improve the overall structural stability of the first bent connecting rod 33, ensuring structural stability during rotation.

[0070] Furthermore, the insulating part 334 connects the first bent sub-rod 331 and the second bent sub-rod 332, meaning that the first bent sub-rod 331 and the second bent sub-rod 332 are not conductive, which helps to reduce the probability of a short circuit caused by the direct connection between the positive and negative terminals of the charging circuit.

[0071] In some embodiments, the linkage mechanism 30 further includes an insulating protective sleeve, which is fitted over the outside of the first bent sub-rod 331 and the second bent sub-rod 332 to reduce the probability of leakage current in the first bent sub-rod 331 and the second bent sub-rod 332.

[0072] In some embodiments, such as Figure 8 As shown, the second curved connecting rod 34 passes through the hollow region 333 between the first curved sub-rod 331 and the second curved sub-rod 332, and is rotatably connected to the first curved sub-rod 331 and the second curved sub-rod 332. That is, the second curved connecting rod 34, located between the first curved sub-rod 331 and the second curved sub-rod 332, helps to increase the structural balance and stability of the linkage mechanism 30 along a third direction. Simultaneously, the first curved sub-rod 331 and the second curved sub-rod 332 also provide a constraint on the second curved connecting rod 34, further enhancing the stability of the linkage mechanism 30.

[0073] In some embodiments, please refer to Figure 11 The plug assembly 20 includes a base 22, with one end of a plurality of prongs 21 inserted into the base 22. The prongs 21 include a first prong 21a and a second prong 21b. The first prong 21a is used for conductive connection to the live wire, and the second prong 21b is used for conductive connection to the neutral wire. That is, the base 22 supports the prongs 21. The first prong 21a is connected to the live wire, and the second prong 21b is connected to the neutral wire, responsible for obtaining alternating current from the power grid and converting it to direct current, thereby enabling the charging unit 10 to provide power to electronic devices.

[0074] It is understood that in other embodiments, the plurality of pins 21 may also include a third pin for connection to a ground wire, which provides additional safety protection to minimize the risk of the charger casing becoming energized.

[0075] For example, such as Figure 9 As shown, the linkage mechanism 30 includes at least two second conductive shafts 32, wherein the two second conductive shafts 32 are spaced apart and coaxially arranged along a third direction, and the two second conductive shafts 32 are respectively located on both sides of the first end 33a of the first bent linkage 33 along the third direction, as shown. Figure 3 As shown, the two second conductive shafts 32 are electrically and rotatably connected to the first pin 21a and the second pin 21b, respectively. That is, the first end 33a of the first bent connecting rod 33 is rotatably connected to the plug assembly 20 through the two second conductive shafts 32. Moreover, the first pin 21a and the second pin 21b are electrically connected to the two second conductive shafts 32, thereby providing electrical energy to the first bent connecting rod 33 through the two second conductive shafts 32, and ultimately providing electrical energy to the charging body 10.

[0076] Please see Figure 3 In an embodiment where the first bending link 33 includes a first bending sub-link 331 and a second bending sub-link 332, one of the second conductive shafts 32 is electrically connected to the first bending sub-link 331, and the other second conductive shaft 32 is electrically connected to the second bending sub-link 332.

[0077] In some embodiments, please refer to Figure 11 The inner wall of the base 22 has two sidewalls spaced apart along a third direction, forming a second sliding groove 222. The linkage mechanism 30 includes a sliding shaft 341, which is located on both sides of the second end 34b of the second curved link 34 along a third direction. The sliding shaft 341 is located within the second sliding groove 222 and can slide along the second sliding groove 222. The second sliding groove 222 rotates with the plug assembly 20. In the unfolded state, the extension direction of the second sliding groove 222 is the first direction, that is, the extension direction of the second sliding groove 222 is approximately parallel to the extension direction of the pin 21.

[0078] For example, please continue reading Figure 11 The inner wall of the base 22 has two side walls spaced apart along the third direction, and the second positioning holes 221 are formed on them. The second positioning holes 221 are used for the second conductive shaft 32 to be inserted to achieve a rotatable connection with the pin 21.

[0079] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the plug assembly 20 includes a protective cover 23, a base 22 located inside the protective cover 23, and the other ends of multiple prongs 21 exposed outside the protective cover 23. The protective cover 23 is an insulator. In its unfolded state, the protective cover 23 has an opening 231 at the end facing the charging body 10, allowing the second conductive shaft 32 to enter and connect with the base 22. The protective cover 23 provides insulation protection for the prongs 21 and the base 22.

[0080] In some embodiments, please refer to Figure 8 and Figure 9 The linkage mechanism 30 includes a connecting shaft 35, a first curved link 33 and a second curved link 34 are rotatably connected through the connecting shaft 35, and define a first rotation axis; the connecting shaft 35 is located at the bend position of the first curved link 33 and at the bend position of the second curved link 34.

[0081] Please see Figure 6 In the stored state, the connecting shaft 35 is located on the side of the charging body 10 facing the first direction, the first curved connecting rod 33 bends and extends in the opposite direction of the first direction along the position of the first rotation axis towards both ends, and the second curved connecting rod 34 bends and extends in the opposite direction of the first direction from the first rotation axis towards both ends.

[0082] In this embodiment, in the retracted state, the first bending link 33 bends and extends in the opposite direction to the first direction from the position of the first rotation axis towards both ends. This means that the bend of the first bending link 33, where the connecting shaft 35 is located, is furthest from the charging body 10 in the first direction, while the positions of the first end 33a and the second end of the first bending link 33 are closer to the charging body 10 in the first direction. In other words, the first bending link 33 bends in the first direction away from the charging body 10, i.e., the first bending link 33 bends towards the first direction. This ensures that, in the retracted state, the first end 33a of the first bending link 33 is inside the plug assembly 20, and the second end 33b of the first bending link 33 is inside the charging body 10.

[0083] Similarly, in the retracted state, the second curved link 34 bends and extends in the opposite direction to the first direction from the position of the first rotation axis towards both ends. This means that the turning position of the second curved link 34, where the connecting shaft 35 is located, is furthest from the charging body 10 in the first direction. The positions of the first end 34a and the second end of the second curved link 34 are both closer to the charging body 10 in the first direction. In other words, the second curved link 34 bends in the first direction away from the charging body 10, i.e., the second curved link 34 bends towards the first direction. Thus, in the retracted state, the first end 34a of the second curved link 34 can be inside the charging body 10, and the second end 34b of the second curved link 34 can be inside the plug assembly 20.

[0084] That is, in the stored state, the plug assembly 20 and the charging body 10 are connected by the first bending link 33 and the second bending link 34.
