[0033] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0034] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.

[0035] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical terms "mounting", "connecting", "connecting", "fixing", "setting" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be directly connected, or it can be indirectly connected. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0036] Chargers are common electronic devices in life, which can be divided into wired chargers and wireless chargers. Among them, the wired charger generally includes a main body and a pin assembly. The main body can include an insulating shell and a circuit board arranged inside the insulating shell. The circuit board can be provided with an input circuit, an output circuit, a transformer and the like. The pin assembly can be connected to the power supply line and connected to the input circuit. The output circuit is used for voltage output. The transformer is coupled between the input circuit and the output circuit to convert voltage.

[0037] The inventor of the present application found that the thickness of the existing charger specification (such as the insulating shell) generally needs to be greater than the spacing of the live pin and the neutral pin, which makes it difficult for the charger (such as the insulating shell) to be thin and light, and inconvenient to carry.

[0038] In order to solve the above problems, the present application provides a charger 1, see Figure 1 , Figure 2 , Figure 3 and Figure 4 , the charger 1 includes a main body 10 and a pin assembly 20. The pin assembly 20 is arranged on the main body 10 and includes three pins. At least one pin can rotate relative to the other pins around a preset axis. The preset axis is arranged apart from the pins. In some embodiments, when the charger 1 is in a storage state, the three pins are arranged along a preset arrangement direction. When the charger 1 is in a plug-in state, the pin that can rotate relative to the other pins is located on one side of the arrangement direction of the other pins, so that the pin assembly 20 is in a plug-in state that can be plugged in.

[0039] In the above manner, at least one of the three pins of the charger 1 can rotate, so that the pins can move between different positions. When the three pins are moved to be collinear (i.e. arranged along the preset arrangement direction) or as collinear as possible, it is convenient to store and carry, thereby making the overall charger 1 relatively thin and light, and reducing the occupied space. When charging is needed, the three pins of the pin assembly 20 can be switched to the plug-in state for plugging in.

[0040] That is, in some embodiments, one of the three pins can rotate, and the other two pins are fixed. In other embodiments, two of the three pins can rotate, and the other pin is fixed.

[0041] The three pins can include a first pin 201 and two second pins 202. The first pin 201 can be a ground pin, and the two second pins 202 can be a live pin and a neutral pin. In addition, the first pin 201 can also be a dummy pin, that is, the first pin 201 can not be used for grounding. Correspondingly, in some embodiments, the first pin 201 can be configured to be rotatable about a preset axis. In some embodiments, one of the second pins 202 can be configured to be rotatable about a preset axis. In some embodiments, the first pin 201 and one of the second pins 202 can be configured to be rotatable about a preset axis. In some embodiments, both of the second pins 202 can be configured to be rotatable about a preset axis.

[0042] The following will be described only by way of example that both of the second pins 202 in the pin assembly 20 can be rotatable about a preset axis, but it can be understood that the following structure and principle are also applicable to the above-mentioned other several embodiments. In addition, it should be noted that the pin assembly can be a British pin, a US three-pin plug, a Japanese three-pin plug, or a Chinese three-pin plug.

[0043] In some embodiments, the first pin 201 can be fixed relative to the main body 10. Both of the second pins 202 can be rotatable relative to the main body 10 about a preset axis. The positional relationship between the two second pins 202 can be relatively fixed. When the charger 1 is in the storage state, the arrangement direction of the two second pins 202 coincides with the preset arrangement direction, and the two second pins 202 and the first pin 201 are arranged along the preset arrangement direction. When the charger 1 is in the plug-in state, the arrangement direction of the two second pins 202 intersects with each other, and the first pin 201 is located on one side of the arrangement direction of the two pins 202.

[0044] In some embodiments, the first pin 201 can be fixed relative to the main body 10. Both of the second pins 202 can be rotatable relative to the main body 10 about a preset axis. The positional relationship between the two second pins 202 can be relatively fixed. When the charger 1 is in the storage state, the arrangement direction of the two second pins 202 coincides with the preset arrangement direction, and the two second pins 202 and the first pin 201 are arranged along the preset arrangement direction. When the charger 1 is in the plug-in state, the arrangement direction of the two second pins 202 intersects with each other, and the first pin 201 is located on one side of the arrangement direction of the two pins 202. Figure 1 Figure 2 As shown in FIG. 6, when the charger 1 is in the storage state, the two second pins 202 are located at the first position, and the two second pins 202 and the first pin 201 are arranged along the preset arrangement direction.

[0045] When the charger 1 is in the plug-in state, as shown in FIG. 7, the two second pins 202 are located at the second position, and the first pin 201 is located on one side of the arrangement direction of the two pins 202. At this time, the arrangement direction of the two second pins 202 can be perpendicular to the preset arrangement direction. Figure 3

[0046] ​​In some embodiments, the main body 10 has a thickness direction. Generally, the thickness of the main body 10 (insulating housing) can be set with reference to the maximum projection distance between the three prongs in the thickness direction. The maximum projection distance can refer to the projection distance of the two prongs that are farthest apart in the thickness direction among the three prongs. When the prong assembly 20 can be switched between the storage state and the plug-in state, the maximum projection distance of the three prongs of the prong assembly 20 in the thickness direction in the storage state can be less than the maximum projection distance of the three prongs of the prong assembly 20 in the thickness direction in the plug-in state, and the thickness of the main body 10 (insulating housing) can be set with reference to the maximum projection distance of the three prongs of the prong assembly 20 in the thickness direction in the storage state.

[0047] In some embodiments, the preset arrangement direction can be perpendicular to the thickness direction. That is, in the storage state, the three prongs can be arranged in line along the preset arrangement direction perpendicular to the thickness direction, thereby reducing the thickness of the main body 10, so that the charger 1 is thinner and lighter.

[0048] In some embodiments, the preset axis can be located between the two second prongs 202, for example, the preset axis can be located substantially at the center of the two second prongs 202. In this case, the rotation amplitude of the two second prongs 202 when rotating between the first position and the second position can be reduced.

[0049] In some embodiments, the charger 1 can include a first housing 211 and a second housing 212 movably arranged on the main body 10. The first housing 211 and the second housing 212 can be arranged on both sides of the prong assembly 20. The first housing 211 and the second housing 212 are rotatably arranged on the main body 10 and are respectively in transmission connection with the two second prongs 202 to be buckled and opened relative to the main body 10.

[0050] When the charger 1 is in the storage state, the first housing 211 and the second housing 212 are buckled relative to the main body 10 to store the prong assembly 20 between the first housing 211 and the second housing 212. When the charger 1 is in the plug-in state, the first housing 211 and the second housing 212 are opened relative to the main body 10 to expose the prong assembly 20. In the above manner, the first housing 211 and the second housing 212 can protect the prong assembly 20 in the storage state when the charger 1 does not need to work.

[0051] In some embodiments, the user can directly rotate the first housing 211 and the second housing 212 by hand to make the first housing 211 and the second housing 212 rotate to be buckled or opened relative to each other.

[0052] Optionally, as Figure 1 and Figure 2As shown, when the charger 1 is in the storage state, the first housing 211 and the second housing 212 are buckled relative to the main body 10 to be in the buckled position. At this time, the first housing 211 and the second housing 212 can be parallel to each other.

[0053] As shown, when the charger 1 is in the storage state, the first housing 211 and the second housing 212 are buckled relative to the main body 10 to be in the buckled position. At this time, the first housing 211 and the second housing 212 can be parallel to each other. Figure 3 As shown, when the charger 1 is in the storage state, the first housing 211 and the second housing 212 are buckled relative to the main body 10 to be in the buckled position. At this time, the first housing 211 and the second housing 212 can be parallel to each other.

[0054] In some embodiments, the first housing 211 and the second housing 212 can be in transmission connection with the two second pins 202. When the first housing 211 and the second housing 212 move from the buckled position to the open position, the two second pins 202 are driven to rotate from the first position to the second position, and the pin assembly 20 is exposed at the open position. In this way, the user can adjust the pin assembly 20 to the plug-in state at the same time when the first housing 211 and the second housing 212 are opened.

[0055] As shown, when the charger 1 is in the storage state, the first housing 211 and the second housing 212 are buckled relative to the main body 10 to be in the buckled position. At this time, the first housing 211 and the second housing 212 can be parallel to each other. Figure 5 and Figure 6 In some embodiments, the pin assembly 20 can include a rotating seat 220 and a linkage assembly 230. The rotating seat 220 is rotatably arranged on the main body 10. The rotating seat 220 can rotate relative to the main body 10 about a preset axis. The two second pins 202 can be arranged on the rotating seat 220. The linkage assembly 230 can be arranged on the main body 10 and connected to the first housing 211 and the second housing 212. The linkage assembly 230 can be in transmission connection with the rotating seat 220 for driving the rotating seat 220 to rotate relative to the main body 10. The linkage assembly 230 is arranged to drive the rotating seat 220 to rotate synchronously during the process that the first housing 211 and / or the second housing 212 rotate from being buckled relative to the main body 10 to being opened relative to the main body 10.

[0056] When the first housing 211 and the second housing 212 move from the buckled position to the open position, the rotating seat 220 can be driven to rotate relative to the main body 10 by the linkage assembly 230 to drive the two second pins 202 to rotate from the first position to the second position.

[0057] In some embodiments, the charger 1 further includes a pin fixing base 240 (see Figure 5). The first prongs 201 can be fixedly arranged in a prong fixing base 240. The rotating seat 220 can be arranged in the prong fixing base 240. In addition, the prong fixing base 240 can be arranged in the main body 10, and the prong fixing base 240 is provided with a receiving groove 241 on the lower side, and the linkage assembly 230 is arranged at least partially in the receiving groove 241.

[0058] In some embodiments, the first shell 211 and the second shell 212 are rotatably arranged in the main body 10. The linkage assembly 230 is arranged to drive the rotating seat 220 to rotate synchronously when the first shell 211 and / or the second shell 212 rotate from the buckling position to the open position. The rotation central axis of the first shell 211 and the second shell 212 can be parallel to the preset arrangement direction. In addition, the rotation central axis of the first shell 211 and the second shell 212 can be located on opposite sides of the three prongs, respectively.

[0059] In some embodiments, referring to Figure 6 and Figure 7 , the rotating seat 220 can include a rotating main shaft 221 arranged along a preset axis. The rotating main shaft 221 can rotate around the preset axis. The linkage assembly 230 can include a main shaft driving member 231. The rotating main shaft 221 is sleeved in the main shaft driving member 231, and the two ends of the main shaft driving member 231 are in transmission connection with the first shell 211 and the second shell 212. The first shell 211 and the second shell 212 are in transmission connection with the rotating main shaft 221 through the main shaft driving member 231. Figure 6 The structure of the transmission connection between the first shell 211 and the main shaft driving member 231 and the rotating main shaft 221 is shown, and the structure of the transmission connection between the second shell 212 and the main shaft driving member 231 can be the transmission connection structure of the first shell 211. The second shell 212 can be arranged on the side of the two second prongs 202 away from the first shell 211.

[0060] The main shaft driving member 231 is used to drive the rotating main shaft 221 to rotate around the preset axis when the main shaft driving member 231 moves along the direction of the preset axis relative to the rotating main shaft 221. That is, the rotating main shaft 221 can convert the linear motion of the main shaft driving member 231 into the rotary motion of the rotating main shaft 221 and the rotating seat 220.

[0061] In some embodiments, referring to Figure 7 The main shaft driving member 231 surrounds at least part of the outer periphery of the rotating main shaft 221. At least part of the outer periphery of the main shaft driving member 231 can be sleeved on the rotating main shaft 221, so that the main shaft driving member 231 can move along the rotating main shaft 221.

[0062] In some embodiments, as Figure 7As shown, the main shaft driving member 231 is provided with a guide protrusion 2310. The outer circumferential surface of the rotating main shaft 221 is provided with a guide groove 2210. The guide protrusion 2310 is embedded in the guide groove 2210. During the movement of the main shaft driving member 231 relative to the rotating main shaft 221, the guide protrusion 2210 slides in the guide groove 2210 to drive the rotating main shaft 221 to rotate.

[0063] In some embodiments, referring to Figure 8 The guide groove 2210 includes a first guide groove 2211 and a second guide groove 2212, which are connected end to end. The first guide groove 2211 is configured to enable the guide protrusion 2310 to drive the rotating main shaft 221 to rotate in a first direction about the preset axis when the guide protrusion 2310 slides along the first guide groove 2211, and the rotating main shaft 221 in turn drives the two second pins 202 to rotate from the first position to the second position. The second guide groove 2212 is configured to enable the rotating main shaft 221 to rotate in a second direction opposite to the first direction about the preset axis when the guide protrusion 2310 slides along the second guide groove 2212, and the rotating main shaft 221 in turn drives the two second pins 202 to rotate from the second position to the first position.

[0064] That is, the extension directions of the first guide groove 2210 and the second guide groove 2210 have both a component along the circumferential direction of the rotating main shaft 221 and a component along the axial direction of the rotating main shaft 221. In some embodiments, the first guide groove 2211 extends spirally about the preset axis, and the extension direction of the first guide groove 2211 intersects with the preset axis. In addition, the first guide groove 2211 and the second guide groove 2212 being connected end to end can mean that the start position of the first guide groove 2211 is connected to the end position of the second guide groove 2212, and the end position of the first guide groove 2211 is connected to the start position of the second guide groove 2212.

[0065] For example, in some embodiments, the first guide groove 2211 has a start position and an end position, and is in communication with the second guide groove 2212 at the start position and the end position, respectively. When the guide protrusion 2310 is located at the start position, the charger is in the storage state. When the guide protrusion 2310 is located at the end position, the charger 1 is in the plugged state.

[0066] In other words, when the guide protrusion 2310 is located at the start position of the first guide groove 2211, the two second pins 202 are located at the first position. When the guide protrusion 2310 is located at the end position of the first guide groove 2211, the two second pins 202 are located at the second position.

[0067] In some embodiments, as Figure 8 and Figure 9As shown, the sidewall of the first guide slot 2211 is provided with a limiting protrusion 2213 protruding towards the slot at the terminal position. The limiting protrusion 2213 is used to stop the guide protrusion 2310 from retreating towards the starting position when the guide protrusion 2310 moves to the terminal position. In this case, when the user opens the first shell 211 and the second shell 212, the plug assembly 20 can remain in the plugged state, reducing the possibility of random shaking of the two second prongs 202 of the plug assembly 20 when in the second position.

[0068] In some embodiments, as shown in Figure 8 As shown, the sidewall of the first guide slot 2211 is provided with a recessed area 2214 recessed outwards of the slot at the starting position. The recessed area 2214 can be used to limit the guide protrusion 2310 in other circumferential directions than the sliding direction of the first guide slot 2211 when the guide protrusion 2310 moves to the starting position, so as to limit the guide protrusion 2310 in the starting position. In this case, when the user closes the first shell 211 and the second shell 212, the guide protrusion 2310 can move to the recessed area 2214, and the plug assembly 20 remains in the storage state, reducing the possibility of random shaking of the two second prongs 202 of the plug assembly 20 when in the first position.

[0069] In some embodiments, as shown in Figure 7 、 Figure 8 and Figure 9 The charger 1 further comprises an elastic reset member 222. The elastic reset member 222 is elastically connected between the rotating main shaft 221 and the main body 10. The elastic reset member 222 is used to be elastically deformed when the charger 1 is in the plugged state. The elastic reset member 222 is used to drive the rotating main shaft 221 to rotate in the second direction and make the guide protrusion 2310 slide along the second guide slot 2210 in the elastic recovery state.

[0070] That is, the elastic reset member 222 can store energy when the rotating main shaft 221 rotates in the first direction, drive the rotating main shaft 221 to rotate in the second direction in the energy release state, and then reset the rotating main shaft 221 and simultaneously switch the first shell 211 and the second shell 212 to the closed state. In some embodiments, the elastic reset member 222 can be a torsion spring, and is sleeved on the rotating main shaft 221, one end of which is connected to the rotating main shaft 221 and the other end of which is connected to the main body 10.

[0071] In some embodiments, the first shell 211 and the second shell 212 can be continuously opened to each other by continuously pulling, so as to drive the guide protrusion 2310 to move out of the terminal position of the first guide slot 2211 and into the second guide slot 2212, thereby making the charger 1 leave the plugged state.

[0072] Optionally, the opening angle of the first shell 211 and the second shell 212 can correspond to the movement of the guide protrusion 2310 from the end position of the first guide slot 2211 to the second guide slot 2212. For example, the first shell 211 and the second shell 212 can continue to be opened, so that when the first shell 211 and the second shell 212 present an angle of 162°, 168°, 175°, etc., the guide protrusion 2310 can pass the limiting protrusion 2213 to enter the second guide slot 2212 to be separated from the end position of the first guide slot 2211.

[0073] In some embodiments, referring to Figure 8 , the second guide slot 2212 can include a transition section 2215 and a reset section 2216. The transition section 2215 and the reset section 2216 are sequentially communicated between the two ends of the first guide slot 2211. The first guide slot 2211 is communicated with the transition section 2215 at the start position and communicated with the reset section 2216 at the end position.

[0074] Wherein, the guide protrusion 2310 enters the transition section 2215 in the process of the charger 1 rotating from the storage state to the plug-in state, and the elastic reset member 222 is used to make the guide protrusion 2310 slide along the transition section 2215 to the reset section 2216 when the elastic reset member 222 is in the elastic recovery state.

[0075] Optionally, as shown in Figure 8 and Figure 9 , the elastic reset member 222 can include a first elastic part 2221 and a second elastic part 2222. The first elastic part 2221 is abutted between the main shaft driving member 231 and the main body 10, and is sleeved on the rotating shaft 221. The second elastic part 2222 is abutted on the main body 10 at one end, and is connected to the first elastic part 2221 and abutted on the rotating shaft 221 at the other end.

[0076] Specifically, in the process of the guide protrusion 2310 sliding from the start position to the end position of the first guide slot 2211, the first elastic part 2221 and the second elastic part 2222 are both in the elastic deformation state. When the guide protrusion 2310 is separated from the end position and enters the transition section 2215, the second elastic part 2222 elastically recovers and pushes the rotating shaft 221 to rotate, so that the guide protrusion 2310 slides in the transition section 2215 and from the transition section 2215 to the reset section 2216. In this process, the second elastic part 2222 is still in the elastic deformation state and the main shaft driving member 231 remains stationary, so that the first shell 211 and the second shell 212 remain stationary, and the rotating shaft 221 rotates to the first position, realizing that the first shell 211 and the second shell 212 are not easily blocked by the rotating shaft 221 in the process of the charger 1 from the plug-in state to the storage state.

[0077] After the guide protrusion 2310 enters the reset section 2216, the first elastic part 2221 elastically recovers and pushes the rotating main shaft 221 to rotate, and at the same time, the first housing 211 and the second housing 212 are driven to rotate to cover each other, so that the charger 1 returns to the storage state.

[0078] Optionally, the first elastic part 2221 can be a spring, and the second elastic part 2222 can be a torsion spring. Of course, in other embodiments, the first elastic part 2221 and the second elastic part 2222 can also be other elastic elements.

[0079] By setting the transition section 2215, the transmission between the first housing 211 and the second housing 212 and the rotating main shaft 221 can be temporarily stopped, and the first housing 211 and the second housing 212 and the rotating main shaft 221 are not easily blocked and stuck with each other, so that the charger 1 can be smoothly returned from the plugged state to the storage state.

[0080] In some embodiments, the extension direction of the transition section 2215 can be perpendicular to the axial direction of the rotating main shaft 221. In this case, when rotating around the rotating main shaft 221, the guide protrusion 2310 moves in the transition section 2215, and the guide protrusion 2310 and the main shaft driving part 231 do not have a component of moving up and down along the axial direction of the rotating main shaft 221, so that the movement of the main shaft driving part 231 can be limited to limit the rotation of the first housing 211 and the second housing 212.

[0081] Of course, in other examples, the transition section 2215 can also be set to enable the main shaft driving part 231 to move when the guide protrusion 2310 slides along the transition section 2215. In this case, the extension direction of the transition section 2215 can have both a component around the circumferential direction of the rotating main shaft 221 and a component along the axial direction of the rotating main shaft 221, so that the first housing 211 and the second housing 212 and the two second pins 202 can be simultaneously retracted.

[0082] In some embodiments, as shown in Figure 8 and Figure 9 The reset section 2216 is set to enable the guide protrusion 2310 to slide along the reset section 2216 and to push the guide protrusion 2310 when the elastic reset part 222 is in the elastic recovery state, and the first housing 211 and the second housing 212 are driven by the main shaft driving part 231 to be buckled relative to the main body part 10.

[0083] In some embodiments, referring to FIG. 22, the depth of the portion of the slot segment where the reset segment 2216 communicates with the first guide slot 2211 is less than the depth of the first guide slot 2211, so as to form a stop step 2217 at the communication between the reset segment 2216 and the first guide slot 2211. The stop step 2217 is used to stop the guide protrusion 2310 from retracting back to the reset segment 2216 when the guide protrusion 2310 slides from the reset segment 2216 to the starting position of the first guide slot 2211. In this case, the possibility of the guide protrusion 2310 of the first guide slot 2211 sliding to the second guide slot 2212 through the communication during the sliding process can be reduced.

[0084] In some embodiments, referring to Figure 9 , the number of the guide grooves 2210 is two. The two guide grooves 2210 can be symmetrically arranged around the central axis of the rotating main shaft 221. Correspondingly, the number of the guide protrusions 2310 is two. The two guide protrusions 2310 are arranged in the two guide grooves 2210, respectively. In this case, the rotating main shaft 221 can be more uniformly stressed, so that the rotating main shaft 221 and the main shaft driving member 231 can work more stably and reliably. In addition, the two guide protrusions 2310 can be connected by a connecting segment to reduce the possibility of the two guide protrusions 2310 sliding out of sync. The connecting segment can be arranged on the periphery of the rotating main shaft 221.

[0085] In some embodiments, referring to Figure 10 and Figure 11 , the linkage assembly 230 includes a first transmission shaft assembly 232. The first transmission shaft assembly 232 is in transmission connection with the first housing 211 and / or the second housing 212, and the first transmission shaft assembly 232 is in transmission connection with the main shaft driving member 231. The first housing 211 and / or the second housing 212 can drive the main shaft driving member 231 to move through the first transmission shaft assembly 232 when the first housing 211 and / or the second housing 212 rotate relative to the main body 10.

[0086] In some embodiments, referring to Figure 11 and Figure 12 , the first transmission shaft assembly 232 includes a first main transmission shaft 2321, a first connecting member 2322, and a gear structure 2323. The first connecting member 2322 can be connected to the first housing 211 to drive the first main transmission shaft 2321 and the gear structure 2323 to rotate when the first housing 211 rotates. The gear structure 2323 can be arranged on the other end of the first main transmission shaft 2321. The main shaft driving member 231 can have a rack structure 2311 that engages with the gear structure 2323. The first transmission shaft assembly 232 is used to convert the rotary motion of the first housing 211 into the linear movement of the main shaft driving member 231.

[0087] The first main transmission shaft 2321 can be arranged in parallel to the rotation direction of the first housing 211 or a preset arrangement direction. The rack structure 2311 can be arranged in parallel to the axis direction of the rotating main shaft 221. In addition, it should be noted that the gear structure 2323 can be a complete gear or a part of the gear (for example, half or one third of the gear).

[0088] In some embodiments, referring to Figure 12 , the first transmission shaft assembly 232 further comprises a first auxiliary transmission shaft 2324 and a second connecting piece 2325. The second connecting piece 2325 can be arranged on the first auxiliary transmission shaft 2324 and connected to the second housing 212. The first main transmission shaft 2321 and the first auxiliary transmission shaft 2324 can be arranged side by side. In this case, the weight difference of the charger 1 on both sides can be reduced.

[0089] In addition, the first main transmission shaft 2321 can be provided with a first synchronous tooth structure 2326. The first auxiliary transmission shaft 2324 is provided with a second synchronous tooth structure 2327, and the first main transmission shaft 2321 and the first auxiliary transmission shaft 2324 can be engaged through the first synchronous tooth structure 2326 and the second synchronous tooth structure 2327. In this case, the first auxiliary transmission shaft 2324 and the first main transmission shaft 2321 can rotate synchronously, thereby synchronously rotating the first housing 211 and the second housing 212. The second connecting piece 2325 can be connected to the second housing 212 to drive the first auxiliary transmission shaft 2324 and the second synchronous tooth structure 2327 to rotate when the second housing 212 rotates.

[0090] In some embodiments, as shown in Figure 12 , the first transmission shaft assembly 232 can further comprise an elastic damping assembly 2328. The elastic damping assembly 2328 is arranged on the first main transmission shaft 2321 and / or the first auxiliary transmission shaft 2324.

[0091] During the rotation of the charger 1 to the plug-in state, the elastic damping assembly 2328 gradually generates elastic compression when the first main transmission shaft 2321 and the first auxiliary transmission shaft 2324 rotate, so as to drive the first housing 211 and the second housing 212 to be buckled to each other relative to the main body 10 during the rotation of the charger 1 from the plug-in state to the storage state.

[0092] Through the above arrangement, the process of smoothly achieving the buckling of the first housing 211 and the second housing 212 to each other can be further ensured, so that the movement of the first housing 211 and the second housing 212 is more accurate and smooth.

[0093] In some embodiments, the elastic damping assembly 2328 can include a first support 23281, an elastic member 23282, and an abutting plate 23283. The first support 23281 is fixedly arranged on the main body 10. The first main transmission shaft 2321 and / or the first auxiliary transmission shaft 2324 can be rotatably arranged in the first support 23281. The first support 23281 and the abutting plate 23283 are arranged in the axial direction of the first main transmission shaft 2321. The elastic member 23282 is arranged between the first support 23281 and the abutting plate 23283.

[0094] In some embodiments, the first main transmission shaft 2321 and / or the first auxiliary transmission shaft 2324 are provided with an abutting block 2329. The abutting plate 23283 is provided with an abutting slope 23284. The abutting block 2329 and the abutting slope 23284 are in abutment. The abutting block 2329 is arranged to move along the abutting slope 23284 when the first main transmission shaft 2321 and / or the first auxiliary transmission shaft 2324 rotate, thereby driving the abutting plate 23283 to move close to the first support 23281 during the rotation of the charger 1 to the plug-in state, and gradually compressing the elastic member 23282. The abutting block 2329 can be integrally formed with the first synchronous tooth structure 2326 and / or the second synchronous tooth structure 2327.

[0095] In some embodiments, the number of the abutting slope 23284 can be one, and the abutting plate 23283 further has a stepped surface 23285 connected head to tail with the abutting slope 23284. When the second synchronous tooth structure 2327 and the first synchronous tooth structure 2326 rotate, the abutting block 2329 pushes the abutting plate 23283 to move in a straight line along the abutting slope 23284, so as to drive the abutting plate 23283 to move close to the first support 23281, and gradually compress the elastic member 23282. When the abutting block 2329 moves to the end of the abutting slope 23284, the abutting block 2329 and the abutting slope 23284 are instantaneously separated. In this process, the stroke of the abutting block 2329 moving along the abutting slope 23284 can be consistent with the stroke of the first housing 211 and the second housing 212 opening from the buckling position to the open position.

[0096] Subsequently, in the process of the elastic restoring member 222 elastically recovering and driving the main shaft driving member 231 to move, the main shaft driving member 231 drives the elastic damping assembly 2328, the elastic member 23282 is reset to drive the abutting plate 23283 to move towards the abutting block 2329, and the abutting block 2329 is moved to the starting point of the abutting slope 23284 again. Thus, the abutting plate 23283 drives the abutting block 2329 to rotate through the abutting slope 23284, and the abutting block 2329 can drive the first housing 211 and the second housing 212 to cover each other through the first synchronous tooth structure 2326 and the second synchronous tooth structure 2327, so as to recover to the buckling position.

[0097] In some embodiments, the number of abutting slopes 23284 is at least two, and the abutting plate 23283 further has a step surface 23285 between any two adjacent abutting slopes 23284. In this case, when the abutting block 2329 reaches the end of one abutting slope 23284, it can abut against the step surface 23285, which can further limit the abutting block 2329, and thus limit the first main transmission shaft 2321 and / or the first auxiliary transmission shaft 2324, to limit the rotation of the first housing 211 and the second housing 212, so as to limit the first housing 211 and the second housing 212 to the buckling position. In some embodiments, the abutting block 2329 has a contact surface 23291 that contacts the abutting slope 23284, and the contact surface 23291 and the abutting slope 23284 are both planar, and the angle between the normal line of the contact surface 23291 and the first main transmission shaft 2321 is equal to the angle between the normal line of the abutting slope 23284 that contacts the contact surface 23291 and the first main transmission shaft 2321. In this case, the contact surface 23291 of the abutting block 2329 can be consistent with the shape of the abutting slope 23284. In other embodiments, the contact surface 23291 can be curved, and the abutting slope 23284 can be planar. For example, the abutting block 2329 can be spherical, and the abutting slope 23284 can be planar. In other embodiments, the contact surface 23291 is curved, and the abutting slope 23284 is curved, and the radius of curvature of the contact surface 23291 is smaller than the radius of curvature of the abutting slope 23284. For example, the contact surface 23291 can be spherical, and the abutting slope 23284 can be arc-shaped.

[0098] In some embodiments, referring to Figure 5 、 Figure 11 and Figure 13 , the linkage assembly 230 further comprises a second transmission shaft assembly 233. The first transmission shaft assembly 232 and the second transmission shaft assembly 233 are respectively arranged at the two ends of the rotating main shaft and are in transmission connection with the main shaft driving member 231. The first transmission shaft assembly 232 can be arranged close to one side of the three prongs, and the second transmission shaft assembly 233 can be arranged close to the live wire side or the zero wire side.

[0099] In some embodiments, the second transmission shaft assembly 233 can be completely identical to the first transmission shaft assembly 232, or can not be completely identical to the first transmission shaft assembly 232, for example, retaining a part of the first transmission shaft assembly 232. In this case, the weight difference between the two ends of the charger 1 can be reduced.

[0100] In some embodiments, the second transmission shaft assembly 233 can include a second main transmission shaft 2331, and a third connecting member 2332 and a gear structure 2323 disposed at both ends of the second main transmission shaft 2331. The third connecting member 2332 is connected to the first housing 211, so as to drive the second main transmission shaft 2331 and the gear structure 2323 to rotate when the first housing 211 rotates.

[0101] In some embodiments, the second transmission shaft assembly 233 can further include a second auxiliary transmission shaft 2334, and a fourth connecting member 2335 disposed at the second auxiliary transmission shaft 2334 and connected to the second housing 212. In addition, the second transmission shaft assembly can further include a second support 2336, and the second main transmission shaft 2331 and the second auxiliary transmission shaft 2334 are disposed side by side and rotatably disposed in the second support 2336.

[0102] In addition, at least one of the first connecting member 2322 and the third connecting member 2332 can be disposed at a side of the first housing 211 facing the second housing 212 (an inner side of the first housing 211). At least one of the second connecting member 2325 and the fourth connecting member 2335 can be disposed at a side of the second housing 212 facing the first housing 211 (an inner side of the first housing 211). In this way, the outer surfaces of the first housing 211 and the second housing 212 can be made more beautiful. In addition, the charger 1 can further include a connecting member fixing cover 213. The connecting member fixing cover 213 can be disposed on the first connecting member 2322, the second connecting member 2325, the third connecting member 2332, or the fourth connecting member 2335, so as to improve the installation reliability of the linkage assembly 230 and make the charger 1 more beautiful.

[0103] Based on the structure of the charger 1, the conversion process of the storage state and the plug-in state of the charger 1 is described as follows:

[0104] In the process of converting the charger 1 from the storage state to the plug-in state, the user can move the first housing 211 and the second housing 212 to open them from the buckling position. The first housing 211 and the second housing 212 drive the first main transmission shaft 2321 and the first auxiliary transmission shaft 2324 to rotate through the first connecting member 2322 and the second connecting member 2325, and the first main transmission shaft 2321 drives the gear structure 2323 to rotate. The gear structure 2323 further drives the main shaft driving member 231 to move upward along the axis direction of the rotating main shaft 221. The main shaft driving member 231 drives the guide protrusion 2310 to move in the process of moving, so as to make the guide protrusion 2310 leave the starting position of the first guide groove 2211.

[0105] Since the depth of the part of the slot segment of the reset segment 2216 communicating with the first guide slot 2211 is less than the depth of the first guide slot 2211, the guide protrusion 2310 enters the first guide slot 2211 first and slides in the first guide slot 2211. The guide protrusion 2310 further drives the rotation main shaft 221 to rotate through the first guide slot 2211, thereby driving the two second pins 202 to rotate to the second position. The rotation main shaft 221 is compressed in the process of rotation, and the main shaft driving member 231 is stretched in the process of rising.

[0106] When the guide protrusion 2310 slides to the end position of the first guide slot 2211, the first shell 211 and the second shell 212 rotate to the open position, and the two second pins 202 rotate to the second position, at which time the charger 1 is in the plugged state. At this time, the limiting protrusion 2213 at the end position of the first guide slot 2211 limits the guide protrusion 2310, so as to further limit and fix the positions of the two second pins 202 and the first shell 211 and the second shell 212.

[0107] In this process, the first main transmission shaft 2321 and / or the first auxiliary transmission shaft 2324 drive the abutting block 2329 to move along the abutting inclined surface 23284, so as to push the abutting plate 23283 to move away from the abutting block 2329, so as to compress the elastic member 23282.

[0108] In the process of converting the charger 1 from the plugged state to the storage state, the user can continue to open the first shell 211 and the second shell 212 by continuing to pinch the first shell 211 and the second shell 212, so as to drive the main shaft driving member 231 to drive the guide protrusion 2310 to disengage from the end position and continue to rise into the transition segment 2215. After the guide protrusion 2310 disengages from the end position, the main shaft driving member 231 remains stationary, so that the first shell 211 and the second shell 212 can remain stationary. At this time, the second elastic part 2222 is further elastically recovered to drive the rotation main shaft 221 to rotate, the guide protrusion 2310 slides relative to the transition segment 2215, and the rotation main shaft 221 further drives the two second pins 202 to rotate from the second position to the first position.

[0109] When the guide protrusion 2310 is slid by the transition section 2215 to the reset section 2216, the first elastic part 2221 elastically recovers and drives the main shaft driving part 231 to move downward to reset, and the main shaft driving part 231 further drives the first shell 211 and the second shell 212 to be buckled to each other through the first transmission shaft assembly 232 and the second transmission shaft assembly 233. And the elastic part 23282 elastically recovers and pushes the abutting plate 23283 to move to the abutting block 2329 direction, the abutting plate 23283 pushes the first synchronous tooth structure 2326 and the second synchronous tooth structure 2327 to rotate through the abutting inclined surface 23284, and drives the first auxiliary transmission shaft 2324 and the first main transmission shaft 2321 to rotate synchronously, thereby further driving the first shell 211 and the second shell 212 to be buckled to each other.

[0110] When the guide protrusion 2310 is slid by the reset section 2216 to the starting position of the first guide groove 2211, the two second pins 202 rotate to the second position. When the abutting block 2329 moves and reaches the end of a certain abutting inclined surface 23284, the abutting block 2329 abuts against the stepped surface 23285, and the first shell 211 and the second shell 212 rotate to the buckled position and are buckled to each other, and the charger 1 is in the storage state at this time.

[0111] The above is the conversion process of the storage state and the plug-in state of the charger 1.

[0112] Through the above-mentioned manner, at least one of the three pins of the charger 1 can rotate, so that the pins can move between different positions, and when the three pins are moved to be collinear (i.e. arranged along the preset arrangement direction) or as collinear as possible, the charger 1 can be conveniently stored and carried, thereby making the whole charger 1 thinner and reducing the occupied space. When charging is needed, the three pins of the pin assembly 20 can be switched to the plug-in state for plug-in.

[0113] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
