[0033] The above figures show examples of the disclosed embodiments of the present application, which will be described in more detail below. These figures and the description are not intended to limit the scope of the concepts of the present application in any way, but rather to explain the concepts of the present application to those skilled in the art with reference to specific examples.

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the following describes the embodiments of the present application in more detail with reference to the drawings.

[0035] An embodiment of the present application provides an adapter, and as shown in FIGS. 1 to 3 , the adapter includes a socket body 1, a guide body 2, a movable conductive sheet 3, and a controller 4. The power acquisition unit 2 is connected to the bottom of the socket body 1, and the power acquisition unit 2 is used to enter the charged guide rail 3 and acquire power. The guide body 2 and the movable conductive sheet 3 are both disposed on the opposite side of the socket body 1 from the jack. The controller 4 is communicatively connected to the movable conductive sheet 3, and is configured to drive the movable conductive sheet 3 to rotate relative to the socket body 1.

[0036] Here, the inside of the socket body 1 has a plug bush, and a jack is provided at a portion of the socket body 1 corresponding to the plug bush. The inside of the socket body 1 may also have a safety door assembly, which is used to close the jack when a plug is not inserted into the jack, thereby improving the safety of the adapter, and the safety door assembly may be an existing safety door assembly, and the specific embodiment thereof will not be described here.

[0037] The guide body 2 is configured to match an opening in the rail and realize a sliding guide of the adapter within the rail.

[0038] The movable conductive sheet 3 is electrically connected to a plug bush inside the socket body 1 at least in a power acquisition state, and is capable of rotating with respect to the socket body 1.

[0039] The controller 4 is configured to drive the movable conductive sheet 3 to rotate relative to the socket body 1, and there can be multiple embodiments. In one possible embodiment, the controller 4 may include a button provided on the outer wall of the socket body 1 and a transmission assembly connected to the button, and the other end of the transmission assembly is connected to the movable conductive sheet 3, so that the movable conductive sheet 3 can be deployed and retracted relative to the guide body 2 by pressing the button. In another possible embodiment, the controller 4 includes a rotating ring and a transmission assembly, see below for details.

[0040] The guide body 2 according to the embodiment of the present application may be fixedly connected to the socket body 1 or rotatably connected to the socket body 1, and the embodiment of the present application is not limited thereto. The following describes the two situations by way of example.

[0041] (1) As shown in Figures 1 to 3, the guide body 2 is fixedly connected to the socket body 1, and the movable conductive sheet 3 can be deployed and retracted relative to the guide body 2 by being driven by a controller 4. The guide body 2 is elongated and fits into the opening of the rail.

[0042] As shown in FIG. 1, when normal power supply by the adapter is required, the movable conductive sheet 3 is deployed relative to the guide body 2, and the movable conductive sheet 3 can contact the rail conductors on the rail.

[0043] When it is necessary to slide the adapter, the controller 4 is operated to drive the movable conductive sheet 3 so as to be stored relative to the guide body 2 until the movable conductive sheet 3 reaches the stored state shown in Fig. 2, at which time the movable conductive sheet 3 is separated from the rail conductor on the rail. After this, the adapter can be slid on the rail without being charged.

[0044] After sliding the adapter to the target position, the controller 4 is operated to move the movable conductive sheet 3 to the deployed state and contact the rail conductor on the rail, and the adapter is in a power acquisition state and can normally supply power to the electrical appliance.

[0045] Possible embodiments of the controller 4 are provided below.

[0046] 3, the controller 4 includes a first rotating ring 41a and a first transmission assembly 42a. The first rotating ring 41a is rotatably connected to the socket body 1. One end of the first transmission assembly 42a is communicatively connected to an inner wall of the first rotating ring 41a, and the other end is communicatively connected (e.g., fixedly connected) to the movable conductive sheet 3.

[0047] Here, the first transmission assembly 42a is used to transmit the rotation of the first rotating ring 41a to the movable conductive sheet 3, and the first rotating ring 41a can rotate in both directions, thereby realizing the deployment and storage of the movable conductive sheet 3 relative to the guide body 2.

[0048] The process by which the controller 4 controls the controller 4 will be described below.

[0049] As shown in FIG. 1, when normal power supply by the adapter is required, the movable conductive sheet 3 is deployed relative to the guide body 2, the movable conductive sheet 3 is in an deployed state, and the movable conductive sheet 3 can contact the rail conductor on the rail.

[0050] When the adapter needs to be slid, the first rotating ring 41a is rotated to drive the movable conductive sheet 3 to be stored relative to the guide body 2 by the first transmission assembly 42a until the movable conductive sheet 3 is in the stored state shown in Fig. 2, at which time the movable conductive sheet 3 is separated from the rail conductor on the rail. After this, the adapter can be slid on the rail without being charged.

[0051] After the adapter is slid to the target position, the first rotating ring 41a is rotated in the opposite direction to the previous direction, moving the movable conductive sheet 3 to the deployed state and contacting the rail conductor on the rail, thereby quickly fixing the adapter to the target position, and at this time, the adapter is in a power acquisition state and can normally supply power to the electrical appliance.

[0052] In one possible embodiment, as shown in Fig. 1, the movable conductive sheet 3 includes an N-pole conductive sheet and an L-pole conductive sheet, which are respectively disposed on both sides of the guide body 2. As shown in Fig. 3, there are two first transmission assemblies 42a, which are respectively communicatively connected to the N-pole conductive sheet and the L-pole conductive sheet, so that the two first transmission assemblies 42a respectively control the retraction and deployment of the corresponding conductive sheet relative to the guide body 2.

[0053] As shown in Figures 1 and 2, in addition to the N-pole conductive sheet and the L-pole conductive sheet, the adapter body also has an E-pole conductor 5, which may be a fixed conductive sheet and protrudes from the guide body 2 in a direction away from the socket body 1.

[0054] A possible embodiment of the first transmission assembly 42a is provided.

[0055] In one possible embodiment, as shown in Fig. 4, the first transmission assembly 42a includes a toggle rod 421a and a transmission rod 422a. The toggle rod 421a matches the inner wall of the first rotating ring 41a. The transmission rod 422a is perpendicular to the toggle rod 421a, one end of the transmission rod 422a is fixedly connected to the mounting portion 420 of the toggle rod 421a, and the other end is fixedly connected to the movable conductive sheet 3, and the mounting portion 420 is disposed between both ends of the toggle rod 421a.

[0056] 5, the inner wall of the first rotating ring 41a has a driving structure 411a, which includes two protrusions 4111a in the circumferential direction. The mounting portion 420 is disposed between the two protrusions 4111a, and the two protrusions 4111a can respectively toggle the mounting portion 420 to drive the toggle rod 421 to rotate. It should be understood that when the first transmission assembly 42a is two, the driving structure 411a on the inner wall of the first rotating ring 41a is also two.

[0057] The transmission principle of the first transmission assembly 42a is as follows.

[0058] The user continues to rotate the first rotating ring 41a, and the two protrusions 4111a on the inner wall of the first rotating ring 41a match the toggle rod 421a, so that the first rotating ring 41a drives the toggle rod 421a to rotate, which in turn drives the transmission rod 422a to rotate, which in turn drives the movable conductive sheet 3 fixedly connected thereto to rotate. By rotating the first rotating ring 41a along two directions, the movable conductive sheet 3 is rotated in two directions, and as a result, the movable conductive sheet 3 is deployed and stored in the guide body 2.

[0059] In order to stabilize the movable conductive sheet 3 in the stored state and the deployed state, in one possible embodiment, as shown in Figures 6 to 11, the first transmission assembly 42a further includes a first driving rod 423a and a first swing spring 424a. The first driving rod 423a is disposed between the toggle rod 421a and the movable conductive sheet 3 and is perpendicular to the transmission rod 422a, one end of the first driving rod 423a is fixedly connected to the transmission rod 422a and the other end abuts on the movable end of the first swing spring 424a. The fixed end of the first swing spring 424a abuts on the inner wall of the socket body 1, and the first swing spring 424a is in a compressed state. The first driving rod 423a has a dead center position and two limit positions, which correspond to the stored state and the deployed state of the movable conductive sheet 3, respectively, and the dead center position is between the two limit positions, and at the dead center position, the axis of the first driving rod 423a overlaps with the axis of the first oscillating spring 424a.

[0060] As shown in Figures 6 and 7, a schematic diagram is shown in which the first drive rod 423a is in one limit position, in which the movable conductive sheet 3 is in a stored state, and this limit position can be called the deployed limit position.

[0061] As shown in FIGS. 8 and 9, a schematic diagram of the first drive rod 423a in a dead center position is shown, in which the axis of the first drive rod 423a overlaps with the axis of the first swing spring 424a.

[0062] As shown in Figures 10 and 11, schematic diagrams are shown in which the first drive rod 423a is in another limit position, in which the movable conductive sheet 3 is in an expanded state, and which can be referred to as the expanded limit position.

[0063] Hereinafter, with reference to FIGS. 6 to 11, an operation state of the first driving rod 423a and the first swing spring 424a in the process in which the first driving rod 423a moves from the retracted limit position to the deployed limit position will be described.

[0064] 6 and 7, the first driving rod 423a is in the storage limit position, and at this time, the movable conductive sheet 3 is in a storage state and contacts the guide body 2. At the same time, the first swing spring 424a is in a compressed state, and applies a pressing force to the first driving rod 423a, which tends to rotate the first driving rod 423a in the direction indicated by the arrow in Fig. 7. As a result, the first driving rod 423a drives the movable conductive sheet 3 to come into close contact with the guide body 2, and the movable conductive sheet 3 enters a stable storage state under the pressing force of the first swing spring 424a.

[0065] When the user rotates the first rotating ring 41a, the first driving rod 423a moves toward the deployment limit position, and in the process, the first driving rod 423a needs to overcome the pressing force of the first swing spring 424a. If the first driving rod 423a has not yet moved to the dead center position shown in Figures 8 and 9, the first driving rod 423a has a tendency to rotate in the direction shown by the arrow in Figure 7 under the pressing force of the first swing spring 424a. Therefore, if the user does not apply any more force to the first rotating ring 41a between the storage limit position and the dead center position, the first driving rod 423a always automatically returns to the storage limit position under the pressing force of the first swing spring 424a.

[0066] The user continues to rotate the first rotating ring 41a, which moves the first driving rod 423a to the dead center position shown in Figures 8 and 9. At the dead center position, the axis of the first driving rod 423a overlaps with the axis of the first swing spring 424a, so that the first driving rod 423a no longer has a tendency to rotate and the direction of the force it receives is shown by the arrow direction in Figure 9. When the user no longer applies an acting force to the first rotating ring 41a at the dead center position, the first driving rod 423a is stabilized at the dead center position.

[0067] By continuing to rotate the first rotating ring 41a, the first driving rod 423a exceeds the dead center position. Under the pressing force of the first swing spring 424a, the first driving rod 423a has a tendency to rotate in the direction shown by the arrow in Fig. 11. Therefore, if the user does not apply any more force to the first rotating ring 41a between the deployment limit position and the dead center position, the first driving rod 423a always automatically returns to the deployment limit position under the pressing force of the first swing spring 424a, as shown in Figs. 10 and 11.

[0068] As can be seen from the above, the first driving rod 423a has three stable positions, namely, the storage limit position, the deployment limit position, and the dead center position, where the dead center position is between the storage limit position and the deployment limit position. When the first driving rod 423a is not subjected to an external force, when it is in any position between the dead center position and the storage limit position, it automatically returns to the storage limit position and is stable at the storage limit position, and when it is in any position between the dead center position and the deployment limit position, it automatically returns to the deployment limit position and is stable at the deployment limit position.

[0069] And because of the automatic return characteristic of the first drive rod 423a, it is not necessary for the first rotating ring 41a to complete the entire movement of driving the first drive rod 423a to move from the storage limit position to the deployment limit position, but the first rotating ring 41a only needs to be able to drive the first drive rod 423a to move from the storage limit position to a position beyond the dead center position, and from the deployment limit position to a position beyond the dead center position. Also, the design in which the first drive rod 423a automatically returns improves the user's tactile feel when operating.

[0070] 6 to 11, the socket body 1 has a first locking groove 12a, and the first drive rod 423a and the first swing spring 424a are disposed in the first locking groove 12a. The first locking groove 12a has a trumpet-shaped opening, and the first swing spring 424a can swing in a space defined by the first locking groove 12a.

[0071] As shown in Figures 6 and 7, when the first drive rod 423a moves to the storage limit position, the first oscillating spring 424a contacts the groove wall of the first engagement groove 12a, and the movable conductive sheet 3 contacts the guide body 2, so that the movable conductive sheet 3 is stabilized in the storage state.

[0072] As shown in FIGS. 10 and 11, when the first driving rod 423a moves to the deployment limit position, the first swing spring 424a comes into contact with another groove wall of the first locking groove 12a.

[0073] 6, 8 and 10, the transmission rod 422a penetrates the socket body 1 on the side opposite to the jack, with a first portion of the transmission rod 422a disposed inside the socket body 1 and a second portion disposed outside the socket body 1. As an option, an end of the second portion of the transmission rod 422a can be pivotally connected to the guide body 2 to make the rotation of the transmission rod 422a more stable.

[0074] The embodiment in which the movable conductive sheet is electrically connected to the first plug bush 11a in the socket body 1 is not limited to the embodiments of the present application.

[0075] 12, the first N-pole plug bush 111a and the first L-pole plug bush 112a of the first plug bush 11a of the socket body 1 are sleeved to the corresponding transmission rod 422a, respectively, and are electrically connected to the corresponding transmission rod 422a. The first E-pole plug bush 113a of the socket body 1 is sleeved to the E-pole conductor 5.

[0076] Here, the material of the transmission rod 422a is a metal material, for example, copper. The transmission rod 422a corresponding to the first N-pole plug bush 111a means the transmission rod 422a fixedly connected to the N-pole plug seat, and the transmission rod 422a corresponding to the first L-pole plug bush 112a means the transmission rod 422a fixedly connected to the L-pole plug seat.

[0077] In the technical solution disclosed in the embodiments of the present application, the first N-pole plug bush 111a and the first L-pole plug bush 112a are respectively sleeved onto the corresponding transmission rod 422a and electrically connected to the corresponding transmission rod 422a, so that the first N-pole plug bush 111a is electrically connected to the N-pole conductive sheet, and the first L-pole plug bush 112a is electrically connected to the L-pole conductive sheet.

[0078] In addition, the plug bush is designed to be set on the transmission rod 422a, so that the contact area between the plug bush and the transmission rod 422a is larger, and effective contact between the plug bush and the transmission rod 422a is ensured during the rotation of the transmission rod 422a, thereby ensuring the stability of the electrical connection. Here, the above-mentioned plug bush refers to the first N-pole plug bush 111a and the first L-pole plug bush 112a.

[0079] In one possible embodiment, as shown in Fig. 13, each of the two side walls of the guide body 2 has a storage groove 21, which is adapted to a corresponding movable conductive sheet 3. Here, the storage groove 21 is used to store the movable conductive sheet 3.

[0080] By providing the storage groove 21, the movable conductive sheet 3 becomes more stable when in the stored state, and the appearance of the adapter is improved.

[0081] In order to prevent the movable conductive sheet 3 from coming off the rail when in the stored state, the adapter according to the embodiment of the present application may further include a locking member 6 and an unlocking member 7 .

[0082] 14, the locking member 6 penetrates the socket body 1 on the side opposite to the jack, and is configured to be engaged inside the rail 01 in the locked state and to be released from the rail 01 in the unlocked state. The unlocking member 7 is connected to the socket body 1, and is configured to switch the locking member 6 between the locked state and the unlocked state.

[0083] The locking member 6 can be switched between a locked state and an unlocked state by operating the unlocking member 7. When the locking member 6 is in the locked state, the locking member 6 is engaged with the inside of the rail 01 (see state C in FIG. 14 for the locked state), and in this way the adapter will not come off the rail 01 and the adapter will be locked into the inside of the rail 01.

[0084] When it is necessary to insert or remove the adapter from the rail 01, the locking member 6 is switched from a locked state to an unlocked state by operating the locking member 7. In this way, the locking member 6 is released from the rail 01 and can freely enter and exit the opening 011 of the rail 01, allowing the adapter to be smoothly inserted or removed.

[0085] In one possible embodiment, the locking member 6 according to the embodiment of the present application can be switched between the locked state and the unlocked state by a rotating manner.

[0086] 15 and 16, the locking member 6 includes a rotating portion 61, a connecting portion 62, and a locking portion 63. Here, the rotating portion 61 penetrates the socket body 1 from the side opposite to the jack, and the rotating portion 61 is rotatable. A first end of the connecting portion 62 is connected to one end of the rotating portion 61 disposed inside the socket body 1, and a second end of the connecting portion 62 is connected to the unlocking member 7. The locking portion 63 is connected to one end of the rotating portion 61 disposed outside the socket body 1, and the locking portion 63 switches between a locked state and an unlocked state by rotating.

[0087] 16, a hole is provided in the side wall of the guide body 2, and the locking portion 63 is disposed in the hole and can rotate to be deployed and stored relative to the guide body 2. When the locking portion 63 is deployed relative to the guide body 2, the locking portion 63 is in a locked state, and when the locking portion 63 is stored relative to the guide body 2, the locking portion 63 is in an unlocked state.

[0088] For example, the rotating part 61 is a cylindrical body, and a via hole is provided on the opposite side of the socket body 1 from the jack at a position corresponding to the locking member 6, and the rotating part 61 can pass through the via hole and rotate within the via hole.

[0089] A first end of the connection part 62 is connected to one end located inside the socket body 1 of the rotating part 61, a second end of the connection part 62 is connected to the unlocking member 7, and the locking part 63 is connected to one end located outside the socket body 1 of the rotating part 61. Therefore, when the unlocking member 7 is operated to act on the connection part 62, the connection part 62 can transmit the action to the rotating part 61 to rotate it, and the rotated rotating part 61 further drives the locking part 63 to rotate, thereby switching the locking part 63 between a locked state and an unlocked state.

[0090] The structure of the connection part 62 is designed adaptively according to the structures of the unlocking member 7 and the rotating part 61, as long as it reliably realizes the above connection. For example, the first end of the connection part 62 connected to the rotating part 61 is a sleeve-like structure, and in this way, the connection is realized by setting the connection part 62 outside the rotating part 61. The second end of the connection part 62 connected to the unlocking member 7 may be any of an arc-shaped block, a rectangular block, and a square block, and the connection method between the second end of the connection part 62 and the unlocking member 7 includes fixed connection or non-fixed connection (e.g., contact only), for example, the connection method between the connection part 62 and the unlocking member 7 is contact connection, clamp connection, magnetic connection, etc.

[0091] In one possible embodiment, as shown in FIG. 7, the lock portion 63 includes a lock portion main body 631 and a lock block 632, in which the lock portion main body 631 is connected to the pivot portion 61, the lock block 632 is connected to the side wall of the lock portion main body 631, and the lock block 632 is stopped by the inner surface of the upper wall arranged on both sides of the opening 011 of the rail 01 in the locked state, that is, the lock block 632 and the inner surface of the upper wall arranged on the side of the opening 011 of the rail 01 are stopped by each other to realize the lock.

[0092] Furthermore, as shown in FIG. 17, the lock portion 63 includes two lock blocks 632, and the two lock blocks 632 are connected to opposing side walls of the lock portion main body 631, that is, arranged on both sides of the lock portion main body 631, respectively. In this way, the two lock blocks 632 and the inner surfaces of the upper walls arranged on both sides of the opening 011 of the rail 01 are locked against each other, which helps to improve the locking effect.

[0093] In the embodiment of the present application, the connection manner between the locking portion body 631 and the second end of the rotating portion 61 includes, but is not limited to, integral molding connection, screw connection, clamp connection, and the like.

[0094] The lock block 632 and the lock body 631 adopt an integrally molded connection to obtain sufficient connection strength. The structure of the lock block 632 includes, but is not limited to, a rectangular block, an arc-shaped block, an angular block, and some irregular blocks with irregular geometric shapes.

[0095] In one possible embodiment, as shown in FIG. 17, the end of the lock block 632 away from the socket body 1 has a guide surface 6321, where the guide surface 6321 is configured to rotate the lock portion 63 from a locked state to an unlocked state by contacting the inner wall of the opening 011 when the lock portion 63 enters the rail opening 011.

[0096] The guide surface 6321 faces the inner wall of the opening 011 of the rail 01, and the structure of the guide surface 6321 meets the following requirements: when the lock block 632 contacts the inner wall of the opening 011 of the rail 01 in the locked state, the inner wall of the opening 011 of the rail 01 presses the lock block 632 based on the contact action, so that the lock part 63 rotates and can smoothly enter the inside of the opening 011, and in the process of entering the inside of the opening 011, the lock block 632 is always pressed by the inner wall of the opening 011, so that the lock part 63 continues to rotate until the lock part 63 rotates to the unlocked state. It should be understood that the two guide surfaces 6321 of the two lock blocks 632 respectively face the two inner walls of the opening 011, so that when the two inner walls respectively press the two lock blocks 632, the smooth rotation of the lock part 63 can be ensured.

[0097] For example, the guide surface 6321 is an inclined surface or an arcuate surface, and the inclination direction of the inclined surface or the radian direction of the arcuate surface is the rotation direction of the lock block 632 for guiding the lock block 632 to rotate.

[0098] As can be seen from the embodiments of the present application, by providing a guide surface 6321 at the end of the lock block 632, when the lock portion 63 enters the opening 011 of the rail 01, the guide surface 6321 comes into contact with the inner wall of the opening 011, thereby rotating the lock portion 63 and automatically rotating the lock portion 63 from the locked state to the unlocked state, improving the user experience. When the adapter is inserted into the rail 01, there is no need to operate the unlocking member 7, that is, the lock portion 63 can be automatically rotated to the unlocked state without any additional operation, so that the adapter can be inserted smoothly and with a good feel when inserted.

[0099] The unlocking member 7 is designed adaptively according to the structure of the locking member 6, and it is only necessary that the unlocking member 7 is capable of rotating the locking member 6 when operated.

[0100] The structure of the lock release member 7 will now be described.

[0101] In one possible embodiment, as shown in Figures 18 and 20, the unlocking member 7 includes an operating portion 71 and a transmission portion 72, where the operating portion 71 is movably connected to the side wall of the socket body 1, a first end of the transmission portion 72 is connected to the operating portion 71, and a second end of the transmission portion 72 is connected to the connection portion 62.

[0102] By operating the actuator, for example by pressing the operating portion 71, the transmitting portion 72 transmits a force to the connecting portion 62 of the locking member 6 to rotate the connecting portion 62. The rotated connecting portion 62 simultaneously rotates the locking portion 63, switching the locking portion 63 from a locked state to an unlocked state.

[0103] The operation method of the operation unit 71 includes, but is not limited to, a pressing method, a toggle method, etc. Examples will be described below.

[0104] As an example, as shown in Figures 14 to 18, operating unit 71 is a button that is operated by pressing it down, and a hole or slot is provided in the side wall of socket body 1 to accommodate operating unit 71 of the button structure, and operating unit 71 can be movably positioned inside the hole or slot by being pressed down.

[0105] In the embodiment of the present application, the side wall of the socket body 1 is also provided with a corresponding hole for accommodating the button-structured actuating part 71, so that the actuating part 71 can be pressed. Here, the actuating part 71 is ergonomically arranged at a position most suitable for the user's thumb to press in order to unlock the adapter in the most comfortable condition, thus making the unlocking process easy and smooth.

[0106] In order to facilitate assembly, the operating part 71 and the transmission part 72 adopt a detachable connection method, for example, the detachable connection method is screw connection, clamp connection, etc.

[0107] Taking the clamp connection method as an example, as shown in FIG. 18, the operating part 71 includes a button section 711 and a connection section 712 connected in sequence. Here, the outer diameter of the connection section 712 is made smaller than the outer diameter of the button section 711, so that a locking step 713 is formed at the connection position between the two. The connection section 7122 has an elastic structure that expands and contracts along the radial direction. For example, the connection section 712 is sleeve-shaped, and a plurality of rectangular holes extending in the axial direction along the circumferential direction are provided on the side wall on which the connection section 712 is arranged, so that the connection section 712 of the operating part 71 expands and contracts along the radial direction. A clamp block 714 is arranged on the outer side of the side wall of the free end of the connection section 712 away from the button section 711. Correspondingly, the part of the transmission part 72 connected to the operating part 71 has a clamp hole. In application, the connection section 712 of the working part 71 is inserted into the clamping hole, and the connection section 712 is compressed radially by being pressed from the inner wall of the clamping hole or by being pressed manually, and the connection section 712 passes through the clamping hole until the wall of the transmission part 72 facing the locking stage 713 is stopped by the locking stage 713. After this, the connection section 712 is not pressed, and the connection section 712 is automatically reset based on its elasticity, at which time the wall of the transmission part 72 away from the locking stage 713 is stopped by the clamp block 714, so that the transmission part 72 is locked between the locking stage 713 and the clamp block 714. In this way, the working part 71 and the transmission part 72 are connected by a clamp connection.

[0108] In order to improve the stability of the transmission part 72, the transmission part 72 may be connected to the socket body 1, for example, the socket body 1 is provided with a slot into which the transmission part 72 is inserted.

[0109] When the operating portion 71 is a button, the transmission portion 72 is configured to transmit the pressing force of the button to the lock portion 63 when the button is pressed, thereby causing the lock portion 63 to rotate.

[0110] For example, as shown in FIG. 18 , the transmission part 72 includes a connecting plate 721, two side reinforcing plates 722, a bottom plate 723 and a push plate 724, in which the connecting plate 721 extends along a direction perpendicular to the operating part 71, the two side reinforcing plates 722 are respectively connected to two opposing side ends of the connecting plate 721 and extend along a direction away from the operating part 71, the bottom plate 723 is perpendicularly connected to the bottom end of the connecting plate 721 and extends along a direction away from the operating part 71, one end of the push plate 724 is connected to the end of the bottom plate 723 away from the connecting plate 721, and the other end of the push plate 724 is connected to the second end of the connecting part 62 (for the specific connection method, refer to the above description of the connection method between the connecting part 62 and the unlocking member 7).

[0111] 17, the unlocking member 7 further includes a torsion spring 73, which is disposed inside the socket body 1 and set in the rotating portion 62, and both ends of the torsion spring 73 respectively contact the inner wall of the socket body 1 and the connecting portion 61. The torsion spring 73 is configured to hold the locking portion 63 in the locked state.

[0112] 17, the spring body of the torsion spring 73 is set in the rotating portion 61 of the locking member 6, one torsion arm of the torsion spring 73 acts on the connecting portion 62 of the locking member 6 by contact, and the other torsion arm of the torsion spring 73 contacts the inner wall of the socket body 1. In this way, when the torsion spring 73 is in the initial state, the elastic force of the torsion spring 73 can hold the locking portion 63 in the locked state, and when an external force acts on the operating portion 71 to rotate the connecting portion 62, the connecting portion 62 presses and deforms the torsion arm with which it comes into contact, and the connecting portion 62 overcomes the elastic force of the torsion spring 73, so that the locking portion 63 can automatically rotate from the locked state to the unlocked state.

[0113] As can be seen from the above, in the embodiment of the present application, by disposing the torsion spring 73, when an operation such as pressing is performed on the operating unit 71, the transmission unit 72 transmits the force of the pressing to the connection unit 62 of the locking member 6, causing the connection unit 62 to rotate. The rotated connection unit 62 presses the torsion spring 73, simultaneously rotating the lock unit 63, switching the lock unit 63 from the locked state to the unlocked state. If the operating unit 71 is not pressed, the pressed torsion spring 73 is automatically reset, which in turn resets the rotating unit 61, and as a result, the lock unit 63 is automatically reset from the unlocked state to the locked state.

[0114] Specifically, after the locking portion 63 is inserted into the accommodating cavity 012 of the rail 01 from the opening 011 of the rail 01, and after the locking portion 63 is ejected from the opening 011 of the rail 01 to the outside of the accommodating cavity 012 of the rail 01, the torsion spring 73 can automatically reset the locking portion 63 from the unlocked state to the locked state.

[0115] When the unlocking member 7 includes a torsion spring 73, it can be automatically reset by the locking member 6, and the connection method between the connection part 62 of the locking member 6 and the unlocking member 7 may be a contact connection. In this way, after the locking part 63 is pressed by the inner wall of the opening 011 of the rail 01 and automatically rotates to the unlocked state, the locking part 63 can be automatically reset from the unlocked state to the locked state by the torsion spring 73, and there is no need to operate the operating part 71 in order to reset the locking part 63 to the locked state.

[0116] As another example, as shown in Figures 19 and 20, the operating portion 71 is a toggle sheet. For example, as shown in Figure 20, the operating portion 71 of the toggle sheet structure includes a toggle section 715 and a second connection section 716, the toggle section 715 is an arc-sheet-shaped structure, a first end of the second connection section 716 is connected to the inner wall of the toggle section 715, and a second end of the second connection section 716 is connected to the transmission portion 72.

[0117] In the embodiment of the present application, the arc degree of the arc sheet-shaped toggle section 715 matches the arc degree of the circular side wall of the socket body 1, and the arc sheet-shaped toggle section 715 is operated to toggle clockwise or counterclockwise along the circumferential direction. To provide a movement space for toggling the operating part 71, the side wall of the case of the socket body 1 is provided with a corresponding arc-shaped strip hole, and the toggle section 715 is attached to the side wall of the adapter case.

[0118] The outer wall of the arc-sheet toggle section 715 may be provided with a rough structure, such as a geometric pattern, to increase the frictional force with the fingers, thereby making the toggle operation less labor-intensive.

[0119] The second connection section 716 is block-shaped, for example, a first end of the second connection section 716 and an inner wall of the toggle section 715 are connected by an integral molding method to improve connection strength, and a second end of the second connection section 716 and the transmission portion 72 are clamp-connected to facilitate assembly.

[0120] For example, a clamp slot is provided on the top surface of the second connection section 716, and a first end of the transmission part 72 is inserted into the clamp slot to enable a clamp connection with the second connection section 716. Furthermore, an arc-shaped slot is provided on the bottom surface of the second connection section 716, and the arc direction of the arc-shaped slot coincides with the toggle direction of the toggle section 715. Correspondingly, an arc-shaped guide block is provided on the side wall of the socket body 1, and when the arc-shaped guide block is disposed in the arc-shaped slot, the operating part 71 moves stably along the toggle track when the toggle section 715 is toggled.

[0121] When the operating portion 71 is a toggle sheet, the transmission portion 72 is configured to transmit the acting force of the toggle sheet to the lock portion 63 when the button is toggled, thereby causing the lock portion 63 to rotate.

[0122] For example, the transmission part 72 is a rod-shaped structure, a first end of the transmission part 72 and the second connection section 716 of the operating part 71 are connected by a clamp connection, and a second end of the transmission part 72 is fixedly connected to the side wall of the connection part 62 of the locking member.

[0123] The actuating portion 71 of the toggle seat structure may be used in combination with a torsion spring 73, specifically see the relevant content of the torsion spring above.

[0124] An embodiment of the present application provides a locking member 6 that can be switched between a locked state and an unlocked state by an extension and retraction movement, and as shown in Figures 21 and 22, the locking member includes a deformation portion 64 and a second locking portion 65, in which the deformation portion 64 penetrates the side of the socket body 1 opposite the jack, and the second locking portion 65 is connected to one end of the deformation portion 64 located below the socket body 1, and the deformation portion 64 can be elastically deformed by the action of the unlocking member 7, so that the second locking portion 65 switches between a locked state and an unlocked state by an extension and retraction movement.

[0125] The deformation portion 64 is elastically deformed by the action of the unlocking member 7, causing the second locking portion 65 to perform an expansion and contraction movement (when expanded, the second locking portion 65 is in a locked state, and when compressed, the second locking portion 65 is in an unlocked state), thereby achieving the purpose of switching the second locking portion 65 between a locked state and an unlocked state.

[0126] Regarding the structure of the deformation portion 64, in one possible embodiment, as shown in FIG. 22, the deformation portion 64 includes a top plate 641, a first side plate 642, and a second side plate 643, where the first side plate 642 and the second side plate 643 are respectively connected to opposite ends of the top plate 641, and have a gap 644 between the first side plate 642 and the second side plate 643, and the second locking portion 65 is respectively connected to a first surface of the first side plate 642 and a second surface of the second side plate 643, where the first surface is the surface away from the gap 644 of the first side plate 642, and the second surface is the surface away from the gap 644 of the second side plate 643.

[0127] The top plate 641 may be either an arc-shaped plate or a flat plate, but an arc-shaped plate is particularly used to facilitate elastic deformation of the deformation portion 64. To simplify the structure, the first side plate 642 and the second side plate 643 are made into elongated rectangular plates. The top plate 641 creates a gap 644 between the first side plate 642 and the second side plate 643, which provides elasticity to the deformation portion 64.

[0128] In the extended state (i.e., in the initial state), the gap 644 exists, so that the two second locking portions 65 are in a locked state, and in the compressed state, the size of the gap 644 decreases, so that the two second locking portions 65 are compressed accordingly and switched to an unlocked state.

[0129] In another possible embodiment, the deformation portion 64 includes two support side plates with a gap facing each other and an elastic member, such as a compression spring, disposed between the two support side plates. A second lock portion 65 (not shown) is connected to a surface of each support side plate away from the gap. In such an embodiment, the elastic member is connected between the two support side plates to provide elasticity to the deformation portion 64.

[0130] In the embodiment of the present application, the structure of the second locking portion 65 is referred to the above description of the locking portion 63, and a description thereof will be omitted here.

[0131] In one possible embodiment, as shown in FIG. 22, the unlocking member 7 includes a second operating portion 74 and a second transmission portion 75, where the second transmission portion 75 is arc-shaped and is positioned inside the socket body 1 (see FIG. 21), and the second operating portion 74 is connected to the outer surface of the second transmission portion 75.

[0132] There are two unlocking members 7, and the deformation portion 64 includes a first deformation portion 645 and a second deformation portion 646, where both ends of the second transmission portion 75 of one unlocking member 7 are connected to the first surfaces of the first deformation portion 645 and the second deformation portion 646, respectively, and both ends of the second transmission portion 75 of the other unlocking member 7 are connected to the second surfaces of the first deformation portion 645 and the second deformation portion 646, respectively.

[0133] Regarding the structures of the first deformation portion 645 and the second deformation portion 646, please refer to the description of the structure of the deformation portion 64 above. That is, both the first deformation portion 645 and the second deformation portion 646 include a top plate 641, a first side plate 642, and a second side plate 643, where the first side plate 642 and the second side plate 643 are respectively connected to both opposing ends of the top plate 641, and a gap 644 exists between the first side plate 642 and the second side plate 643.

[0134] Both ends of the second transmission portion 75 of one unlocking member 7 are connected to the first surface of the first side plate 642 of the first deformation portion 645 and the second deformation portion 646, respectively, and both ends of the second transmission portion 75 of the other unlocking member 7 are connected to the second surface of the second side plate 643 of the first deformation portion 645 and the second deformation portion 646, respectively.

[0135] In application, the distance between the two second transmission parts 75 can be reduced by simultaneously pressing the two second operating parts 74, and the second transmission part 75 transmits the force of the pressing to the first deformation part 645 and the second deformation part 646 of the unlocking member 7, thereby reducing the length of the gap 644 between the first deformation part 645 and the second deformation part 646, so that the two second lock parts 65 connected to the first deformation part 645 and the two second lock parts 65 connected to the second deformation part 646 are all compressed correspondingly and switched to the unlocked state (see the unlocking process shown in FIG. 14). If the second operating part 74 is not pressed, the deformation part 64 is automatically reset by its elasticity and returns to the locked state.

[0136] Based on the above-described configurations of the locking member 6 and the unlocking member 7, the adapter insertion process will be described below with reference to FIG. 14, taking an example in which the unlocking member 7 is a button.

[0137] Referring to step A of FIG. 14, before inserting the adapter inside the rail 01, align the adapter with the opening 011 of the rail 01.

[0138] 14, when the adapter is inserted into the rail 01, that is, when the locking portion 63 enters the opening 011 of the rail 01 from the outside, the guide surface 6321 comes into contact with the inner wall of the opening 011, thereby rotating the locking portion 63, and when the locking portion 63 rotates by a certain angle, for example, 90°, the locking portion 63 is completely stored. In this case, there is no obstacle between the opening 011 of the rail 01 and the guide body 2, and the adapter can be smoothly inserted into the receiving cavity 012 of the rail 01.

[0139] Referring to step C of FIG. 14, when the adapter is fully inserted inside the accommodating cavity 012 of the rail 01, there is no interaction force between the opening 011 of the rail 01 and the locking portion 63, and the locking portion 63 returns to its initial locked state due to the action of the torsion spring 73. In this case, the lock block 632 of the locking portion 63 is misaligned with the opening 011 of the rail 01, and the adapter will not come off the rail due to the action of a normal external force.

[0140] In one possible embodiment, when the adapter is removed from inside the rail 01, that is, when the locking portion 63 enters the opening 011 of the rail 01 from the accommodation cavity 012, the operating portion 71 is pressed down to finally drive the locking portion 63 to rotate, and when the locking portion 63 rotates to a certain angle, for example 90°, the locking portion 63 is completely stored. In this case, there is no obstacle between the opening 011 of the rail 01 and the power acquisition unit 2, and the adapter can be smoothly removed from the opening 011 of the rail 01.

[0141] (2) As shown in Figures 24 and 25, the guide body 2 is rotatably connected to the socket body 1 and is communicatively connected to the controller 4. The movable conductive sheet 3 is fixedly connected to the guide body 2, and the controller 4 can drive the guide body 2 to rotate the movable conductive sheet 3. Exemplarily, the guide body 2 is cylindrical, and the outer diameter matches the size of the opening of the rail, thereby playing the role of a guide.

[0142] Possible embodiments of the controller 4 are provided below.

[0143] 25 and 26, the controller 4 includes a second rotating ring 41b and a second transmission assembly 42b. The second rotating ring 41b is rotatably connected to the socket body 1. One end of the second transmission assembly 42b is communicatively connected to an inner wall of the second rotating ring 41b, and the other end is communicatively connected to the guide body 2 (for example, fixedly connected).

[0144] When the second rotating ring 41b is rotated, the rotation of the second rotating ring 41b is transmitted to the guide body 2 by the second transmission assembly 42b, and ultimately to the movable conductive sheet 3, thereby achieving rotation of the movable conductive sheet 3 relative to the socket body 1.

[0145] When the adapter needs to supply power normally, the adapter is attached to the rail, and the movable conductive sheet 3 is in the power acquisition position and contacts the rail conductor on the rail. When the adapter needs to slide, the second rotating ring 41b is rotated, and the movable conductive sheet 3 is driven by the second transmission assembly 42b to rotate to the power off position, in which case the movable conductive sheet 3 is separated from the rail plug bush on the rail, after which the adapter can slide normally on the rail without being charged.

[0146] After the adapter is slid to the target position, the second rotating ring 41b is rotated in the opposite direction to the previous direction to drive the movable conductive sheet 3 to rotate to the power acquisition position and contact the rail plug bush on the rail, thereby quickly fixing the adapter to the target position, and at this time, the adapter is in a power acquisition state and can normally supply power to the electrical appliance.

[0147] Possible embodiments of the second transmission assembly 42b are provided below.

[0148] 26, the second transmission assembly 42b includes a transmission shaft 421b, an active gear 422b, a driven gear 423b, and a center gear 424b. The active gear 422b and the driven gear 423b are fixedly connected to both ends of the transmission shaft 421b, respectively. The active gear 422b meshes with the inner wall of the second rotating ring 41b, and the driven gear 423b meshes with the center gear 424b. The center gear 424b is fixedly connected to the guide body 2, and is coaxial with the guide body 2.

[0149] Hereinafter, the transmission principle by which the second rotating ring 41b controls the movable conductive sheet 3 to rotate will be described.

[0150] 27, the user rotates the second rotating ring 41b, and the internal gear structure on the inner wall of the second rotating ring 41b meshes with the active gear 422b, so that the second rotating ring 41b drives the active gear 422b to rotate. Since both the active gear 422b and the driven gear 423b are fixed to the transmission shaft 421b, the active gear 422b drives the driven gear 423b to rotate via the transmission shaft 421b. Since the driven gear 423b meshes with the center gear 424b, the driven gear 423b drives the center gear 424b to rotate, which in turn drives the guide main body 2 to rotate, and the guide main body 2 drives the movable conductive sheet 3 to rotate. By rotating the second rotating ring 41b along two directions, the movable conductive sheet 3 can be rotated in two directions, thereby switching the movable conductive sheet 3 between the power off position and the power acquisition position.

[0151] In one possible embodiment, there are two transmission shafts 421b, two active gears 422b and two driven gears 423b, and the two active gears 422b both mesh with the inner wall of the second rotating ring 41b, and the two driven gears 423b both mesh with the center gear 424b, thereby making the transmission of rotation smoother.

[0152] In one possible embodiment, the active gear 422b and the driven gear 423b may be imperfect gears, so that the occupation of the space inside the socket body 1 is reduced.

[0153] 27, in order to limit the rotation range of the movable conductive sheet 3, the inside of the socket body 1 has a second locking groove 14b. When the movable conductive sheet 3 rotates to the power acquisition position, the center gear 424b is locked to one groove wall of the second locking groove 14b, and when the movable conductive sheet 3 rotates to the power off position, the center gear 424b is locked to the other groove wall of the second locking groove 14b.

[0154] In one possible embodiment, under the restriction of the second locking groove 14b, the movable conductive sheet 3 can complete a rotation range of 90°, and the two limit positions locked by the second locking groove 14b respectively correspond to the power-off position and the power-acquiring position of the movable conductive sheet 3. In addition, in order for the user to easily understand the power-off position and the power-acquiring position of the movable conductive sheet 3, corresponding marks may be set on the outer wall of the socket body 1.

[0155] In order to stabilize the movable conductive sheet 3 in the power-off position and the power acquisition position, as shown in Figures 27 and 28, the second transmission assembly 42b further includes a swing spring 425b, and the swing spring 425b is perpendicular to the guide body 2. The fixed end of the swing spring 425b is connected to the groove bottom of the second locking groove 14b, the movable end of the swing spring 425b is connected to the center gear 424b, and the swing spring 425b is in a compressed state. The second locking groove 14b has a trumpet-shaped opening, and the swing spring 425b can swing in the space defined by the second locking groove 14b, and can drive the center gear 424b to rotate toward the groove wall of the second locking groove 14b.

[0156] As shown in Fig. 27, the center gear 424b has a spring connection part 4241b, which has a through hole, and the movable end of the swing spring 425b has a connecting column 4251b, which is inserted into the through hole of the spring connection part 4241b to form a hinge between the swing spring 425b and the center gear 424b. In this way, while the swing spring 425b rotates following the center gear 424b, the connecting column 4251b rotates with respect to the through hole, making the swing of the swing spring 425b smoother. The groove bottom of the second locking groove 14b has a locking column, and the fixed end of the swing spring 425b is sleeved into the locking column. In addition, the number of oscillating springs 425b may be two, and the two oscillating springs 425b are arranged symmetrically inside the socket body 1, and accordingly, the center gear 424b may be provided with two spring connection portions 4241b symmetrically, and the two spring connection portions 4241b are respectively connected to the two oscillating springs 425b.

[0157] As shown in state A of FIG. 28, a schematic diagram is shown in which the center gear 424b contacts one groove wall of the second locking groove 14b, and this position can be considered as the power-off position of the movable conductive sheet 3.

[0158] As shown in state B of FIG. 28, a schematic diagram of the position where the axis of the oscillating spring 425b intersects with the axis of the guide body 2 is shown, and this position can be considered as the dead center position or critical position of the movable conductive sheet 3.

[0159] As shown in state C of FIG. 28, a schematic diagram is shown in which the center gear 424b contacts another groove wall of the second locking groove 14b, and this position can be considered as the power acquisition position of the movable conductive sheet .

[0160] Hereinafter, with reference to FIG. 28, the operating states of the center gear 424b and the swing spring 425b when the movable conductive sheet 3 rotates from the power-off position to the power acquisition position will be described.

[0161] As shown in state A of Fig. 28, since the swing spring 425b is in a compressed state, a pressing force is applied to the center gear 424b, and the pressing force causes the center gear 424b to tend to rotate in the direction shown by the arrow in Fig. 29. As a result, the swing spring 425b brings the center gear 424b into close contact with the groove wall of the second locking groove 14b, and the movable conductive sheet 3 is maintained in a stable state in the power-off position.

[0162] The user rotates the second rotating ring 41b to move the movable conductive sheet 3 toward the power acquisition position, and in the process, the center gear 424b needs to overcome the pressing force of the swing spring 425b. If the center gear 424b has not yet moved to the dead center position shown in state B of FIG. 28, the center gear 424b has a tendency to rotate in the direction indicated by the arrow in state A of FIG. 28 under the pressing force of the swing spring 425b. Therefore, if the user does not apply any more force to the second rotating ring 41b between the power off position and the dead center position, the movable conductive sheet 3 will always automatically return to the power off position under the pressing force of the swing spring 425b.

[0163] The user continues to rotate the second rotatable ring 41b, thereby moving the center gear 424b to the dead center position shown in state B of Fig. 28. At the dead center position, the axis of the center gear 424b overlaps with the axis of the swing spring 425b, so that the center gear 424b no longer has a tendency to rotate, and the direction in which it receives force is shown by the arrow direction in state B of Fig. 28. When the user no longer applies force to the second rotatable ring 41b at the dead center position, the movable conductive sheet 3 is stabilized at the dead center position.

[0164] As the user continues to rotate the second rotatable ring 41b, the center gear 424b passes beyond the dead center position. Under the urging force of the swing spring 425b, the center gear 424b has a tendency to rotate in the direction indicated by the arrow in state C of Fig. 28. Therefore, if the user does not apply any more force to the second rotatable ring 41b between the power acquisition position and the dead center position, the conductive sheet assembly 4 always automatically returns to the power acquisition position under the urging force of the swing spring 425b.

[0165] As can be seen from the above, the movable conductive sheet 3 (or the center gear 424b) theoretically has three stable positions, namely, the power off position, the power acquisition position, and the dead center position, where the dead center position is between the power off position and the power acquisition position. When the movable conductive sheet 3 is not subjected to an external force, when it is in any position between the dead center position and the power off position, it automatically returns to the power off position and is stable in the power off position, and when it is in any position between the dead center position and the power acquisition position, it automatically returns to the power acquisition position and is stable in the power acquisition position.

[0166] And because of the automatic return characteristic of the movable conductive sheet 3, the second rotating ring 41b does not need to complete the entire movement of driving the movable conductive sheet 3 to move from the power off position to the power acquisition position, but only needs to be able to drive the movable conductive sheet 3 to move from the power off position to a position beyond the dead center position, and from the power acquisition position to a position beyond the dead center position. In addition, the automatic return design of the movable conductive sheet 3 also improves the user's operating feel, and allows the movable conductive sheet 3 to be quickly rotated to the power acquisition position or the power off position.

[0167] Since the second plug bush 11b is fixed inside the socket body 1 and the movable conductive sheet 3 can rotate relative to the socket body 1, the movable conductive sheet 3 rotates relative to the second plug bush 11b. When the movable conductive sheet 3 rotates to the power acquisition position, in order to keep the movable conductive sheet 3 always electrically connected to the second plug bush 11b, as shown in FIG. 29, the adapter further includes a built-in conductive sheet 8, which is disposed inside the socket body 1. The built-in conductive sheet 8 is fixedly connected to the guide body 2 and electrically connected to the movable conductive sheet 3. The built-in end of the second plug bush 11b has a built-in plug bush 111b, and the position and shape of the built-in plug bush 111b are consistent with the built-in conductive sheet 8, so that during the process of the movable conductive sheet 3 rotating, the built-in conductive sheet 8 can be inserted into and removed from the built-in plug bush 111b.

[0168] 29, the built-in conductive sheet 8 is separated from the built-in plug bush 111b. In this case, the movable conductive sheet 3 is in the power-off position.

[0169] 29, the built-in conductive sheet 8 is inserted into the built-in plug bush 111b, and the second plug bush 11b and the movable conductive sheet 3 are electrically connected by the built-in conductive sheet 8. In this case, the movable conductive sheet 3 is in the power acquisition position, and the movable conductive sheet 3 can acquire power from the rail and supply it to the second plug bush 11b.

[0170] The built-in conductive sheet 8 and the movable conductive sheet 3 may be an integral copper strip.

[0171] In addition to the above-mentioned technical solution of arranging the built-in plug bush 111b and the built-in conductive sheet 8, the movable conductive sheet 3 may be connected to the corresponding second plug bush 11b via a flexible connecting wire, and in this embodiment, the second plug bush 11b is always maintained in an electrically connected state. During the process of rotating the movable conductive sheet 3, the flexibility of the flexible connecting wire prevents the electrical connection between the second plug bush 11b and the movable conductive sheet 3 from being cut off.

[0172] In an embodiment of the present application, a rail socket is further provided, as shown in FIG. 30, the rail socket includes a rail 01 and an adapter 02 as described in any of the above technical solutions.

[0173] The specific structure of the rail 01 varies depending on the adapter 02 docked thereto. Below, the structure of the rail 01 and the process of using the adapter 02 will be described using an example in which the rail 01 is docked to the adapter 02 shown in Figures 1 to 13.

[0174] 14, the upper and inner parts of the rail 01 respectively have an opening 011 and a receiving cavity 012 extending along the longitudinal direction of the rail 01. A soft protective strip 013 made of, for example, silica gel is disposed on both sides of the upper wall of the opening 011, where the soft protective strip 013 extends along the longitudinal direction of the opening 011. The use of the soft protective strip 013 can prevent impurities from falling into the receiving cavity 012 and protect the components inside the receiving cavity 012, and at the same time, since it is soft, it does not affect the insertion and removal of the adapter.

[0175] If the user uses it improperly or if it is subjected to a significant external force, the adapter may be forcibly detached from the charging guide rail. However, the existence of the soft protective strip 013 prevents the adapter 02 from being damaged during this forced detachment process, and serves to protect the adapter 02, while at the same time preventing damage to the locking member.

[0176] As shown in FIG. 31, the conductor inside the accommodating cavity 012 includes two rail conductive sheets 014 and an E-pole rail plug bush 015, the two rail conductive sheets 014 being respectively an L-pole rail conductive sheet and an N-pole rail conductive sheet, the L-pole rail conductive sheet and the N-pole rail conductive sheet being arranged opposite each other and parallel to the insertion direction of the rail groove.

[0177] The process of using adapter 02 will be described below.

[0178] When supplying power using a rail socket, first the movable conductive sheet 3 of the adapter 02 is controlled to be in a stored state, then the guide body 2 of the adapter 02 is inserted into the accommodating cavity 012, and then the first rotating ring 41a is rotated to unfold the movable conductive sheet 3 and bring it into contact with the rail conductive sheet 014, and the adapter 02 enters a power acquisition state.

[0179] When it is desired to slide the adapter 02, the first rotating ring 41a is rotated to store the movable conductive sheet 3, the movable conductive sheet 3 is separated from the rail conductive sheet 014, and the adapter 02 is turned off. After this, the adapter 02 can be slid without being charged.

[0180] As shown in state A of FIG. 31, the movable conductive sheet 3 of the adapter 02 is in a stored state, the movable conductive sheet 3 is not in contact with the rail conductive sheet 014 of the rail 01, and the adapter 02 is in a power-off state.

[0181] 31, the movable conductive sheet 3 of the adapter 02 is in an unfolded state, and the movable conductive sheet 3 is in contact with and electrically connected to the rail conductive sheet 014 on the rail 01. This allows the movable conductive sheet 3 to obtain power from the corresponding rail conductive sheet 014, and the adapter 02 is in a power obtaining state.

[0182] Also, in the above two cases, the E-pole conductor 5 contacts the E-pole rail plug bushing 015 on the rail 01.

[0183] The above are merely preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of the present application.
