The above-mentioned drawings have shown clear embodiments of this application, which will be described in more detail later. These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0097] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0098] It should be noted that, in this article, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. Optionally, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context in the specific embodiment.

[0099] It should be understood that, although the terms first, second, third, etc. may be used to describe various information in this article, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "at the time of..." or "when..." or "in response to determination". Furthermore, as used in this article, the singular forms "one", "one" and "the" are intended to also include plural forms, unless there is an opposite indication in the context. It should be further understood that the terms "comprising", "including" indicate that there are described features, steps, operations, elements, components, projects, kinds, and / or groups, but do not exclude the existence, occurrence or addition of one or at least one other feature, step, operation, element, component, project, kind, and / or group. The terms "or", "and / or", "including at least one of the following" etc. used in this application can be interpreted as inclusive, or mean any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”, and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will only occur when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0100] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0101] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0102] The embodiment of the present application provides a charging head and a charger, in which a passive pin and an active pin are hinged by a connecting piece, so that the active pin and the passive pin can be synchronously linked during the process of unfolding or folding. When either the active pin or the passive pin is unfolded or folded, the other pin can be driven to unfold or fold as well, thereby making the unfolding and folding of the charging head easier to achieve.

[0103] The principles and features of the embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the scope of the present application.

[0104] refer to Figure 1-Figure 4 The charging head provided in the embodiment of the present application may include a housing 100 and a pin assembly 200. The pin assembly 200 may include an active pin 210, a passive pin 220 and a connector 230.

[0105] Optionally, the active pin 210 and the passive pin 220 have a fixed end and a free end, and the fixed end 211 of the active pin 210 and the fixed end 221 of the passive pin 220 are both rotatably connected to the shell 100, that is, the active pin 210 and the passive pin 220 can both rotate relative to the shell 100 along their respective rotation axes, so that the active pin 210 and the passive pin 220 can be unfolded when the charging head is needed, and can be folded when the charging head is not needed.

[0106] Optionally, refer to Figure 3 , Figure 4-Figure 8 The housing 100 may include a bottom shell 110 and a pressure cover 120 , the bottom shell 110 and the pressure cover 120 are arranged to form an accommodating space, the pin assembly 200 is arranged in the accommodating space, and the free end 212 of the active pin 210 and the free end 222 of the passive pin 220 can both extend to the outside of the bottom surface 115 of the bottom shell 110 .

[0107] Optionally, the fixed end 211 of the active pin 210 can be constructed with a first connecting rod 213, the bottom shell 110 can be constructed with a first connecting half hole, and the pressure cover 120 can be constructed with a second connecting half hole. After the bottom shell 110 and the pressure cover 120 are connected together, the first connecting half hole and the second connecting half hole form a first connecting hole, and the first connecting rod 213 can be rotatably inserted into the first connecting hole. The active pin 210 can rotate relative to the shell 100 with the axis of the first connecting rod 213 as the center, thereby realizing a rotatable connection between the active pin 210 and the shell 100.

[0108] Optionally, the passive pin 220 and the housing 100 can be rotatably connected in a manner similar to the active pin 210, that is, the fixed end 221 of the passive pin 220 can be configured with a second connecting rod 224, and the axis of the second connecting rod 224 can be parallel to the axis of the first connecting rod 213. The bottom shell 110 can be configured with a third connecting half hole, and the pressure cover 120 can be configured with a fourth connecting half hole. After the bottom shell 110 and the pressure cover 120 are connected together, the third connecting half hole and the fourth connecting half hole are surrounded to form a second connecting hole. The second connecting rod 224 is rotatably inserted into the second connecting hole, and the passive pin 220 can rotate relative to the housing 100 with the axis of the second connecting rod 224 as the center, thereby realizing the rotatable connection between the passive pin 220 and the housing 100.

[0109] refer to Figure 4 When installing the active pin 210 and the passive pin 220 to the housing 100, the active pin 210 and the passive pin 220 can be placed on the bottom shell 110, and the first connecting rod 213 is placed in the first connecting half hole, and the second connecting rod 224 is placed in the third connecting half hole. Then, the pressure cover 120 is buckled with the bottom shell 110. Figure 5 In this way, the first connecting rod 213 can be fixed in the first connecting hole, and the second connecting rod 224 can be fixed in the second connecting hole, so that the active pin 210 and the passive pin 220 can be assembled with the housing 100 more easily.

[0110] Optionally, the active pin 210 and the passive pin 220 are hinged by a connector 230, and the active pin 210 drives the passive pin 220 to unfold or fold synchronously through the connector 230, so that the active pin 210 and the passive pin 220 can be synchronously linked during the unfolding or folding process, so that either the active pin 210 or the passive pin 220 can drive the other to unfold or fold during the unfolding or folding process, thereby making the unfolding and folding process of the charging head easier to achieve.

[0111] refer to Figure 2 and Figure 3The outer side of the housing 100 may be configured with an active pin receiving slot 111 and a passive pin receiving slot 112 , and the positions of the active pin receiving slot 111 and the passive pin receiving slot 112 correspond to the positions of the active pin 210 and the passive pin 220 , respectively.

[0112] Optionally, in an implementation in which the housing 100 includes the bottom shell 110 and the pressure cover 120 , the active pin receiving groove 111 and the passive pin receiving groove 112 may be configured on the bottom shell 110 .

[0113] Optionally, the pin assembly 200 has a folded state and an unfolded state. The pin assembly 200 is in the folded state (refer to Figure 1 ), the active pin 210 and the passive pin 220 are respectively received in the active pin receiving slot 111 and the passive pin receiving slot 112 to hide the active pin 210 and the passive pin 220. The pin assembly 200 is in the unfolded state (refer to Figure 2 ), the active pin 210 and the passive pin 220 are respectively moved out of the active pin receiving slot 111 and the passive pin receiving slot 112.

[0114] refer to Figure 2 Optionally, a finger groove 113 may be constructed on the outer side of the shell 100. The finger groove 113 may be a groove constructed on the bottom surface 115 of the bottom shell 110. The finger groove 113 is connected to the active pin receiving groove 111. When the pin assembly 200 is in a folded state, the free end 212 of the active pin 210 extends into the finger groove 113.

[0115] When the active pin 210 needs to be removed from the active pin receiving slot 111, a finger or other tool can be inserted into the finger slot 113, and then an external force can be applied to the free end 212 of the active pin 210 to rotate the active pin 210 relative to the housing 100 and rotate from the folded state to the unfolded state. The finger slot 113 can facilitate the user to apply an external force to the active pin 210, so that the active pin 210 can be more easily removed from the active pin receiving slot 111.

[0116] In some possible implementations, the connecting member 230 may include a connecting rod, the active pin 210 can rotate relative to the connecting rod with a first rotation axis L1 as the center, and the passive pin 220 can rotate relative to the connecting rod with a second rotation axis L2 as the center; the active pin 210 can rotate relative to the shell 100 with a third rotation axis L3 as the center, and the third rotation axis L3 is parallel to the first rotation axis L1 and is not colinear; the passive pin 220 can rotate relative to the shell 100 with a fourth rotation axis L4 as the center, and the fourth rotation axis L4 is parallel to the second rotation axis L2 and is not colinear; the line between the first rotation axis L1 and the second rotation axis L2 intersects with the line between the three rotation axes and the fourth rotation axis L4.

[0117] Optionally, refer to Fig.10 and Fig.11 A third connecting rod 214 may be constructed on the active pin 210 , the axis of the third connecting rod 214 may be parallel to and not colinear with the axis of the first connecting rod 213 , and the third connecting rod 214 may be rotatably disposed on the connecting rod.

[0118] Optionally, a fourth connecting rod 225 may be configured on the passive pin 220 , the axis of the fourth connecting rod 225 may be parallel to and not colinear with the axis of the second connecting rod 224 , and the fourth connecting rod 225 may be rotatably disposed on the connecting rod.

[0119] Optionally, the active pin 210 and the passive pin 220 may be rotated toward each other through the connector 230 to fold the active pin 210 and the passive pin 220 ; or the active pin 210 and the passive pin 220 may be rotated away from each other through the connector 230 to unfold the active pin 210 and the passive pin 220 .

[0120] In an implementation in which the connecting member 230 includes a connecting rod, the third connecting rod 214 can be arranged on a side of the first connecting rod 213 that is close to the free end 212 of the active pin 210 and away from the second connecting rod 224, and the fourth connecting rod 225 can be arranged on a side of the second connecting rod 224 that is away from the fixed end 221 of the passive pin 220 and close to the first connecting rod 213.

[0121] Optionally, when the pin assembly 200 is in the unfolded state, the active pin 210 is rotated toward the passive pin 220, and since the position of the first connecting rod 213 remains unchanged, the third connecting rod 214 also rotates around the first connecting rod 213 toward the passive pin 220. In this process, since the position of the second connecting rod 224 remains unchanged, and due to the connection of the connecting rods, the distance between the third connecting rod 214 and the fourth connecting rod 225 remains unchanged, so the fourth connecting rod 225 rotates around the second connecting rod 224 in a direction away from the active pin 210, thereby driving the passive pin 220 to rotate toward the active pin 210, that is, the active pin 210 and the passive pin 220 rotate simultaneously and rotate toward each other until the active pin 210 and the passive pin 220 are both in the folded state.

[0122] refer to Fig.12Optionally, when the pin assembly 200 is in the expanded state, an avoidance notch 231 may be constructed on one side of the connecting rod facing the first connecting rod 213, and a portion of the edge of the avoidance notch 231 located between the axes of the first connecting rod 213 and the third connecting rod 214 may be arc-shaped, and the center of the circle corresponding to the arc may be located on the axis of the first connecting rod 213, and the first connecting rod 213 is disposed in the avoidance notch 231, and the first connecting rod 213 is spaced apart from the edge of the avoidance notch 231.

[0123] Optionally, during the rotation of the active pin 210, the first connecting rod 213 rotates along the edge of the arc-shaped avoidance gap 231 relative to the axis of the third connecting rod 214. The avoidance gap 231 can avoid the space required for the first connecting rod 213 to rotate relative to the third connecting rod 214. This can reduce the length of the connecting rod along the thickness direction of the charging head (perpendicular to the bottom surface 115), thereby reducing the thickness of the charging head.

[0124] Optionally, refer to Fig.10 and Fig.11 The active pin 210 may include a ground pin, and the passive pin 220 may include a live pin 226 and a neutral pin 227. For example, the charging head may be a British standard charging head, and the structure and position arrangement of the ground pin, the live pin 226 and the neutral pin 227 all conform to the standards of the British standard charging head.

[0125] refer to Figure 9-11 In this embodiment, there can be two connecting rods, the live wire pin 226 and the grounding pin are hinged by one connecting rod, and the neutral wire pin 227 and the grounding pin are hinged by another connecting rod. The second rotation axis L2 between one connecting rod and the live wire pin 226 and the second rotation axis L2 between the other connecting rod and the neutral wire pin 227 can be arranged in a colinear manner; the first rotation axis L1 between one connecting rod and the grounding pin and the first rotation axis L1 between the other connecting rod and the grounding pin can be arranged in a colinear manner, so that the live wire pin 226 and the neutral wire pin 227 can rotate synchronously with the grounding pin at the same time, thereby improving the synchronization between the live wire pin 226 and the neutral wire pin 227.

[0126] In other embodiments, the connecting member 230 may include a transmission assembly, which may include a driving gear and a passive gear. The driving gear is connected to the first connecting rod 213 and rotates with the first connecting rod 213. The passive gear is connected to the second connecting rod 224 and rotates with the second connecting rod 224. The driving gear and the passive gear are meshed. When the first connecting rod 213 rotates, the second connecting rod 224 is driven to rotate through the transmission assembly, so that the active pin 210 and the passive pin 220 rotate towards each other to fold the active pin 210 and the passive pin 220; or the active pin 210 and the passive pin 220 can be rotated away from each other through the transmission assembly to unfold the active pin 210 and the passive pin 220.

[0127] Optionally, refer to Fig.10 and Fig.11 The charging head may further include an elastic member 240 , which is connected to the shell 100 , abuts against the fixed end 221 of the passive pin 220 , and applies an elastic force to the passive pin 220 , and the direction of the elastic force is from the fixed end 221 of the passive pin 220 to the free end 222 of the passive pin 220 .

[0128] Optionally, in an implementation in which the housing 100 includes the bottom shell 110 and the gland 120 , the elastic member 240 may be connected to the gland 120 by fastening bolts.

[0129] Optionally, the elastic member 240 abuts against the fixed end 221 of the passive pin 220, and the elastic force applied by the elastic member 240 on the passive pin 220 presses the passive pin 220 tightly, so that the passive pin 220 can be kept in the unfolded state or the folded state, thereby improving the stability of the positions of the active pin 210 and the passive pin 220. Since the passive pin 220 and the active pin 210 are hinged by the connecting member 230, when the passive pin 220 is pressed tightly, the active pin 210 is not easy to rotate. In this way, when the pin assembly 200 is in the folded state, the active pin 210 is not easy to move out of the active pin receiving groove 111, and the passive pin 220 is not easy to move out of the passive pin receiving groove 112; when the pin assembly 200 is in the unfolded state, the positions of the active pin 210 and the passive pin 220 are not easy to be misaligned, so that the active pin 210 and the passive pin 220 can be more easily inserted into the power plug.

[0130] In some embodiments, the elastic member 240 may include a spring sheet having a connecting end 241 and a movable end 242 , wherein the connecting end 241 is connected to the housing 100 , and the movable end 242 abuts against the passive pin 220 .

[0131] The spring piece has a simple structure and is easy to assemble with the housing 100 , and the spring piece is not easily damaged, thereby increasing the service life of the charging head.

[0132] Optionally, refer to Figure 12-Figure 15 The fixed end 221 of the passive pin 220 may be configured with a protrusion 223, and the protrusion 223 is located on the side of the passive pin 220 that is away from the free end 222 of the passive pin 220. Correspondingly, the side of the spring sheet facing the passive pin 220 may be configured with a slide groove 243, and the slide groove 243 extends from the movable end 242 to the connecting end 241, and the protrusion 223 is slidably disposed in the slide groove 243.

[0133] Optionally, when the passive pin 220 rotates around the axis of the second connecting rod 224 , the protrusion 223 slides along the slide groove 243 , thereby reducing the resistance of the spring sheet to the rotation of the passive pin 220 and making the rotation of the passive pin 220 smoother.

[0134] Optionally, the edge of the protrusion 223 may be in an arc shape to reduce the friction between the protrusion 223 and the elastic sheet during the rotation of the passive pin 220 .

[0135] Optionally, the slide groove 243 may further include a locking groove 244, which is located at one end of the slide groove 243 close to the connecting end 241, and the inner wall of the locking groove 244 is arc-shaped. After the passive pin 220 is unfolded, the protrusion 223 is clamped in the locking groove 244, and the protrusion 223 and the passive pin 220 are not easy to rotate relative to the spring sheet, so that the passive pin 220 remains in the unfolded state.

[0136] Optionally, the spring sheet may be configured with a limiting portion 245 , which cooperates with the housing 100 and limits the spring sheet from moving in a direction parallel to the rotation axis of the passive pin 220 .

[0137] In some implementations, the limiting portion 245 may include a limiting hole, the axis of the limiting hole is perpendicular to the rotation axis of the passive pin 220, and a limiting column 114 may be constructed on the shell 100, and the limiting column 114 is inserted into the limiting hole to limit the freedom of the spring piece along the direction parallel to the rotation axis of the passive pin 220.

[0138] In some other implementations, the limiting portion may include a limiting column, the axis of which is perpendicular to the axis of the passive pin 220 , and a limiting hole may be constructed on the shell 100 , in which the limiting column is passed to limit the freedom of the spring sheet along a direction parallel to the rotation axis of the passive pin 220 .

[0139] refer to Figure 3 In some embodiments, the charging head may further include a circuit board 300 and a face shell 400 .

[0140] Optionally, the passive pin 220 is electrically connected to the circuit board 300 , so that the charging head can transmit current through the passive pin 220 .

[0141] In the implementation in which the passive pin 220 includes a live pin 226 and a neutral pin 227 , the live pin 226 and the neutral pin 227 are electrically connected to the circuit board 300 so that the charger can transmit current through the live pin 226 and the neutral pin 227 .

[0142] Optionally, the shell 100 and the circuit board 300 are both disposed in the surface shell 400, and the shell 100 and the surface shell 400 enclose an installation space. The circuit board 300 is disposed in the installation space, and the shell 100 and the circuit board 300 are both hidden in the surface shell 400, so that the appearance structure of the charging head is more concise.

[0143] In other embodiments, the elastic member 240 may include a spring, one end of which is connected to the housing 100, and the other end of the spring abuts against the passive pin 220 and applies elastic force to the passive pin 220, and the direction of the elastic force is from the fixed end 221 of the passive pin 220 to the free end.

[0144] The elastic force exerted by the spring on the passive pin 220 presses the passive pin 220 tightly, so that the passive pin 220 can be kept in an unfolded state or a folded state, thereby improving the position stability of the active pin 210 and the passive pin 220 .

[0145] An embodiment of the present application also provides a charger, comprising the charging head in any of the above embodiments.

[0146] Optionally, the charger also includes a charging cable.

[0147] Optionally, the charging cable is connected to the circuit board 300 in the charging head, and is electrically connected to the passive pin 220 of the charging head through the circuit board 300.
