Description

Technical Field

[0001] This application belongs to the field of electric vehicle charging technology, and specifically relates to an adapter. Background Technology

[0002] A charging gun adapter is a device used to connect different types of electric vehicles and charging stations. It connects the charging gun on the charging station and the socket on the electric vehicle by contact, enabling electrical connection between charging guns and sockets with incompatible interfaces, thereby satisfying the interoperability of physical connections of various standard charging interfaces.

[0003] However, existing charging gun adapters lack safety locks, posing a risk of being forcibly pulled out during electric vehicle charging, potentially damaging the charging dock or adapter. Utility Model Content

[0004] In view of the above situation, it is necessary to provide an adapter with a safety lock that allows the adapter and charging gun to be separated only after the connection between the adapter and the socket is disconnected.

[0005] This application provides an adapter for connecting a charging gun to a socket on an electric vehicle, such that the charging gun and the socket are electrically connected for charging the electric vehicle. The adapter includes a housing, a first limiting component, a second limiting component, and a third limiting component, all of which are movably disposed within the housing. When the adapter and the charging gun are plugged in, the first limiting component is connected to the charging gun to restrict separation between the adapter and the charging gun. When the adapter and the socket are plugged in, the socket abuts against a first portion of the second limiting component, causing a second portion of the second limiting component to abut against the first limiting component. The second portion restricts the movement of the first limiting component relative to the housing, keeping the first limiting component in a state of limiting connection to the charging gun. The third limiting component is connected to the socket to restrict separation between the adapter and the socket. When the adapter and the socket switch from a plugged-in state to a disconnected state, the first part separates from the socket, the second part separates from the first limiting component, and the second limiting component returns to its initial state. At this time, the first limiting component can move relative to the housing to release the connection between the first limiting component and the charging gun. The charging gun and the adapter can be separated from each other by pulling them apart.

[0006] In some embodiments of this application, the first limiting component includes a first limiting member and a first elastic member. The first limiting member is rotatably connected to the housing and includes a first limiting portion for limiting the connection of the charging gun, thereby restricting the separation action between the adapter and the charging gun. The first elastic member connects the housing and the first limiting member and provides a first elastic force to drive the first limiting member to rotate. This first elastic force drives the first limiting portion to limit the connection of the charging gun. When the first limiting portion is connected to the charging gun, pressing the end of the first limiting member away from the first limiting portion can drive the first limiting member to rotate, separating the first limiting portion from the charging gun.

[0007] In some embodiments of this application, the first limiting member further includes a limiting groove; when the adapter and the socket are plugged into each other, the second part is plugged into the limiting groove to limit the rotation of the first limiting member relative to the housing.

[0008] In some embodiments of this application, the second limiting component includes a second limiting member and a second elastic member. The second limiting member is movably connected to the housing, with the first portion and the second portion located at opposite ends of the second limiting member. The second elastic member connects the housing and the second limiting member, and provides a second elastic force to drive the second limiting member to move relative to the housing, the second elastic force driving the second portion to extend toward the socket. When the adapter and the socket are plugged into each other, the second elastic member is compressed and deformed.

[0009] In some embodiments of this application, the second limiting member further includes a connecting portion that connects the first part and the second part, the first part and the second part being located on opposite sides of the connecting portion; the axis of the first part and the axis of the second part are parallel to each other and not collinear.

[0010] In some embodiments of this application, the second limiting member is in the shape of a "Z".

[0011] In some embodiments of this application, the adapter further includes a guide hole, the second portion being disposed in the guide hole and capable of telescopic movement relative to the adapter along the guide hole.

[0012] In some embodiments of this application, the third limiting component includes a third limiting member and a third elastic member. The third limiting member is rotatably connected to the housing and includes a third limiting portion for limiting its connection to the socket, thereby restricting separation between the adapter and the socket. The third elastic member connects the housing and the third limiting member and provides a third elastic force to drive the third limiting member to rotate, thereby driving the third limiting portion to remain connected to the socket. When the third limiting portion is connected to the socket, pressing the end of the third limiting member away from the third limiting portion can drive the third limiting member to rotate, separating the third limiting portion from the socket.

[0013] In some embodiments of this application, the adapter further includes a power-off sensor disposed within the housing; when the third limiting component limits the connection to the socket and the adapter transmits electrical energy to the charging gun and the socket, when the limiting connection of the third limiting component to the socket is released, the third limiting component can trigger the power-off sensor, and the power-off sensor sends a command to the electric vehicle to stop charging.

[0014] In some embodiments of this application, the adapter further includes a conductive terminal assembly disposed in the housing; when the adapter is connected to the charging gun and the socket, the conductive terminal assembly is electrically connected to the charging gun and the socket.

[0015] In summary, the adapter provided in this application, when connecting the charging gun and the socket, uses a first limiting component to limit the connection of the charging gun and a third limiting component to limit the connection of the socket. This ensures a stable connection of the charging gun to the socket via the adapter, guaranteeing stable charging of the electric vehicle. Furthermore, the second limiting component, under the action of the socket, moves to the position limiting the connection of the first limiting component, restricting the separation between the adapter and the charging gun. After the adapter and the socket separate, the second limiting component returns to its initial state and separates from the first limiting component. At this time, the first limiting component can move relative to the housing to unlock the adapter and the charging gun, allowing them to separate. This adapter only allows the adapter and the charging gun to separate after disconnecting from the socket, achieving "power off before unplugging," which helps protect the electric vehicle and avoids the risk of damage to the adapter due to forcefully pulling out the charging gun, thus extending the adapter's service life.

[0031] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. When an element is considered to be "set" on another element, it can be directly set on the other element or there may be an intervening element.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0037] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0038] like Figures 1 to 3 As shown, an embodiment of this application provides an adapter 100 for connecting a charging gun 200 and a socket 310 on an electric vehicle 300, thereby electrically connecting the charging gun 200 and the socket 310 to charge the electric vehicle 300. Specifically, the adapter 100 and the charging gun 200, and the adapter 100 and the socket 310, are connected by a plug-in connection. In other embodiments, the adapter 100 and the charging gun 200, or the adapter 100 and the socket 310, may also be connected by a magnetic connection.

[0039] As an example, the following description will further illustrate the connection between the adapter 100 and the charging gun 200, and between the adapter 100 and the socket 310, both of which are plug-in connections.

[0040] In one embodiment, the adapter 100 includes a housing 10, a first limiting component 20, and a third limiting component 40, both of which are movably disposed on the housing 10.

[0041] When the adapter 100 and the charging gun 200 are plugged into each other, the first limiting component 20 and the charging gun 200 are connected to each other to limit the separation between the adapter 100 and the charging gun 200. Furthermore, by adjusting the first limiting component 20, the limiting connection between the first limiting component 20 and the charging gun 200 can be released, at which point the charging gun 200 and the adapter 100 can be separated by pulling them apart.

[0042] When the adapter 100 and the socket 310 are plugged into each other, the third limiting component 40 and the socket 310 are connected to each other to limit the separation between the adapter 100 and the socket 310. Furthermore, by adjusting the third limiting component 40, the limiting connection between the third limiting component 40 and the socket 310 can be released. At this time, the adapter 100 can be pulled out of the socket 310 of the electric vehicle 300 by pulling or unplugging it.

[0043] By setting the first limiting component 20 and the third limiting component 40, the stability and reliability of the adapter 100 connecting the charging gun 200 and the socket 310 can be guaranteed, thereby improving the stability of using the charging gun 200 to charge the electric vehicle 300.

[0044] like Figures 3 to 5 As shown, in one embodiment, the adapter 100 further includes a second limiting component 30 movably disposed in the housing 10, the second limiting component 30 including a first portion 311 and a second portion 312 disposed opposite to each other at both ends.

[0045] When the adapter 100 and the socket 310 are plugged into each other, the socket 310 abuts against the first part 311 (e.g., Figure 3 As shown), and by pushing the second limiting component 30 toward the charging gun 200 through the first part 311, the second part 312 abuts against the first limiting component 20, wherein the second part 312 abuts against the first limiting component 20 (as shown). Figure 4 As shown, the second limiting component 30 can be used to limit the movement of the first limiting component 20 relative to the housing 10, so that the first limiting component 20 remains in a state of limiting connection to the charging gun 200. That is, the second limiting component 30 can be used as a mechanism to lock the first limiting component 20, restricting the movement of the first limiting component 20, thereby keeping the first limiting component 20 locked to the charging gun 200.

[0046] like Figure 6 and Figure 7 As shown, further, when the adapter 100 and the socket 310 switch from the plugged state to the disconnected state, the first part 311 and the socket 310 separate, the thrust of the socket 310 on the second limiting component 30 disappears, the second limiting component 30 can be reset and moved, so that the second part 312 and the first limiting component 20 separate. At this time, the second limiting component 30 returns to the initial state, the locking of the second limiting component 30 on the first limiting component 20 is released, the first limiting component 20 can move relative to the housing 10 to release the connection between the first limiting component 20 and the charging gun 200, and the charging gun 200 and the adapter 100 can be separated from each other by pulling.

[0047] Therefore, by setting the second limiting component 30, the adapter 100 is only allowed to separate from the charging gun 200 after the connection with the socket 310 is disconnected, realizing "power off first and then unplug the gun", which is beneficial to protect the electric vehicle 300 and avoid the risk of damaging the adapter 100 due to the forceful removal of the charging gun 200, thus extending the service life of the adapter 100.

[0048] like Figure 8 As shown, in one embodiment, the adapter 100 further includes a power-off sensor 50, which is disposed within the housing 10 and adjacent to the third limiting component 40. When the third limiting component 40 switches from a limited connection state to an unlocked separation state with the socket 310, the third limiting component 40 can trigger the power-off sensor 50, causing the power-off sensor 50 to send a command to the electric vehicle 300 to stop charging. That is, during the process of unlocking the third limiting component 40, the power-off sensor 50 can be used to trigger the electric vehicle 300 to stop charging, realizing "power off before unplugging the adapter 100," which helps protect the electric vehicle 300 and reduces the risk of damage to the electric vehicle 300 due to unplugging the charging gun without disconnecting the power.

[0049] In one embodiment, the power failure sensor 50 is a contact switch or a proximity switch. During the process of unlocking the third limiting member 41, a portion of the structure of the third limiting member 41 can move to contact the power failure sensor 50 or move to the sensing range of the power failure sensor 50, thereby triggering the power failure sensor 50 to send a command to the electric vehicle 300 to stop charging.

[0050] In one embodiment, the adapter 100 further includes a conductive terminal assembly 60 disposed in the housing 10. When the adapter 100 is connected to the charging gun 200 and the socket 310, the conductive terminal assembly 60 is electrically connected to the charging gun 200 and the socket 310, and the conductive terminal assembly 60 is used to transmit electrical energy between the charging gun 200 and the socket 310.

[0051] In one embodiment, when the adapter 100 is connected to the charging gun 200, one end of the conductive terminal assembly 60 is plugged into the charging gun 200. In another embodiment, when the adapter 100 is connected to the socket 310, the other end of the conductive terminal assembly 60 is plugged into the socket 310.

[0052] like Figure 4 , Figure 9 and Figure 10As shown, in one embodiment, the first limiting component 20 includes a first limiting member 21, which is rotatably connected to the housing 10. The first limiting member 21 includes a first limiting portion 211. By rotating the first limiting member 21 relative to the housing 10, the first limiting portion 211 can rotate to a position that limits the connection to the charging gun 200. At this time, the first limiting portion 211 can be used to restrict the separation action between the adapter 100 and the charging gun 200, so that the adapter 100 and the charging gun 200 can be stably connected. In one embodiment, the first limiting portion 211 and the charging gun 200 are connected by a snap-fit ​​mechanism to achieve the limiting connection.

[0053] In one embodiment, a first inclined surface (not shown) is provided on the first limiting part 211 or the charging gun 200. When the charging gun 200 and the adapter 100 are plugged into each other, the first limiting part 211 contacts the first inclined surface on the charging gun 200, or the charging gun 200 contacts the first inclined surface on the first limiting part 211. The first inclined surface can play a guiding role, guiding the relative movement between the first limiting part 211 and the charging gun 200 through the force between them, causing the first limiting member 21 to rotate slightly, and then engaging with the charging gun 200 through the first limiting part 211. It can be understood that by providing the first inclined surface, it is beneficial for the first limiting member 21 and the charging gun 200 to achieve the engaging action.

[0054] In one embodiment, the first inclined surface is disposed at the end of the first limiting part 211. Compared with the charging gun 200, the first limiting member 21 is smaller, and disposing of the first inclined surface on the first limiting member 21 is beneficial to saving the processing and manufacturing cost of the adapter 100.

[0055] In one embodiment, the first limiting component 20 further includes a first elastic element 22, which connects the housing 10 and the first limiting element 21. The first elastic element 22 provides a first elastic force to drive the first limiting element 21 to rotate, thereby driving the first limiting portion 211 to rotate toward the position where it is connected to the charging gun 200. When the first limiting portion 211 is connected to the charging gun 200, the first elastic force provided by the first limiting element 21 helps to improve the stability of the connection between the first limiting element 21 and the charging gun 200, reducing the risk of separation due to shaking or vibration, and thus improving the stability of the connection between the adapter 100 and the charging gun 200.

[0056] Furthermore, by pressing the end of the first limiting member 21 away from the first limiting part 211, the first limiting member 21 can be driven to rotate in another direction, causing the first limiting part 211 to separate from the charging gun 200. At this time, the first limiting member 21 is in the unlocked position relative to the charging gun 200, and the adapter 100 and the charging gun 200 can be separated by pulling or unplugging. The part pressed when unlocking the first limiting member 21 and the first limiting part 211 are located at opposite ends of the rotation axis of the first limiting member 21.

[0057] In one embodiment, the first elastic element 22 is a compression spring or a tension spring. When the first elastic element 22 is a compression spring, the first elastic element 22 and the first limiting portion 211 are located at opposite ends of the rotation axis of the first limiting member 21. When the first elastic element 22 is a tension spring, the first elastic element 22 and the first limiting portion 211 are located at the same end of the rotation axis of the first limiting member 21.

[0058] In one embodiment, the adapter 100 or the charging gun 200 may not have a first inclined surface. Instead, when the adapter 100 and the charging gun 200 are plugged in, the end of the first limiting member 21 that is away from the first limiting part 211 is pressed manually. After the two are plugged in, the first limiting member 21 is released, so that the first limiting part 211 rotates to the position where it engages with the charging gun 200 under the action of the first elastic force.

[0059] In one embodiment, the first limiting member 21 further includes a limiting groove 212. When the adapter 100 and the socket 310 are plugged into each other, the opening of the first limiting groove 212 faces the socket 310, and the second part 312 is inserted into the limiting groove 212. By having the second part 312 on the second limiting component 30 inserted into the limiting groove 212, the rotation of the first limiting member 21 relative to the housing 10 can be restricted, so that when the adapter 100 and the socket 310 are in the plugged-in state, the adapter 100 and the charging gun 200 are also in a stable plugged-in state, and the adapter 100 and the charging gun 200 are in a plugged-in locked state. This setting requires the user to disconnect the plugged-in state between the adapter 100 and the socket 310 before charging the charging gun 200, that is, to disconnect the charging state of the electric vehicle 300, which helps to protect the electric vehicle 300 and prevents damage to the electric vehicle 300 caused by directly unplugging the charging gun 200.

[0060] like Figures 3 to 5 , Figures 11 to 13As shown, in one embodiment, the second limiting component 30 includes a second limiting member 31, which is movably connected to the housing 10. The first part 311 and the second part 312 mentioned above are located at opposite ends of the second limiting member 31. The second limiting member 31 is movably disposed on the housing 10 along the insertion direction of the adapter 100 and the socket 310. The first part 311 extends toward the socket 310. When the adapter 100 and the socket 310 are inserted, the socket 310 can push the second limiting member 31 toward the charging gun 200 by abutting against the first part 311, so that the second part 312 at the other end is inserted into the limiting groove 212 on the first limiting member 21.

[0061] In one embodiment, the first part 311 is located inside the housing 10 but does not protrude from the housing 10. It only abuts against the socket 310 when a portion of the structure on the socket 310 is inserted into the housing 10. This arrangement of the first part 311 enables the housing 10 to protect the first part 311 and reduces the risk of foreign objects damaging the first part 311.

[0062] In one embodiment, the second limiting component 30 further includes a second elastic element 32, which connects the housing 10 and the second limiting component 31. The second elastic element 32 provides a second elastic force that drives the second limiting component 31 to move relative to the housing 10. The direction of the second elastic force provided by the second elastic element 32 is opposite to the direction in which the socket 310 pushes the second limiting component 31 to move. That is, when the force exerted by the socket 310 on the second limiting component 31 decreases or disappears, the second elastic force can drive the second portion 312 to move towards the socket 310, causing the second limiting component 31 to return to its initial state. By providing the second elastic element 32, the second limiting component 31 can be stably maintained in its initial state when not subjected to external force (e.g., the force exerted by the socket 310), and can return to its initial state after the external force disappears, which is beneficial to improving the reliability of the second limiting component 30.

[0063] In one embodiment, the second elastic element 32 is a compression spring and is sleeved on the second limiting element 31. When the adapter 100 and the socket 310 are plugged into each other, the second elastic element 32 is compressed and deformed, and the second elastic force is the compression rebound force. Optionally, the compression spring can be sleeved on the second part 312.

[0064] In one embodiment, the second limiting member 31 further includes a connecting portion 313, which connects the first portion 311 and the second portion 312, with the first portion 311 and the second portion 312 located on opposite sides of the connecting portion 313.

[0065] In one embodiment, the axis of the first part 311 and the axis of the second part 312 are parallel to each other and not collinear. In this embodiment, the second limiting member 31 is designed to be irregularly shaped, which helps to avoid other components inside the housing 10, improves the space utilization within the adapter 100, and reduces the overall volume of the adapter 100.

[0066] In one embodiment, the second limiting member 31 is Z-shaped.

[0067] In one embodiment, if the second elastic member 32 is a compression spring, the second elastic member 32 can be sleeved on the second part 312, and the two ends of the second elastic member 32 respectively abut against the connecting part 313 and the housing 10.

[0068] In one embodiment, the housing 10 is provided with a guide hole 11, and the second portion 312 is disposed in the guide hole 11 and can extend and retract relative to the adapter 100 along the guide hole 11. By providing the guide hole 11, the movement of the second limiting member 31 relative to the housing 10 can be limited and guided, improving the accuracy and stability of the movement of the second limiting member 31, thereby improving the reliability of the adapter 100. In other embodiments, the first portion 311 can also be disposed in the guide hole 11. The extending direction of the guide hole 11 is parallel to the insertion direction between the adapter 100 and the socket 310.

[0069] like Figure 4 and Figure 8 As shown, in one embodiment, the third limiting component 40 includes a third limiting member 41, which is rotatably connected to the housing 10. The third limiting member 41 includes a third limiting portion 411. By rotating the third limiting member 41 relative to the housing 10, the third limiting portion 411 can rotate to a position that limits the connection to the socket 310. At this time, the third limiting portion 411 can be used to restrict the separation action between the adapter 100 and the socket 310, so that the adapter 100 and the socket 310 are stably connected. In one embodiment, the limiting connection between the third limiting portion 411 and the socket 310 is achieved by a snap-fit.

[0070] In one embodiment, a second inclined surface 3101 is provided on the third limiting part 411 or the socket 310. When the socket 310 and the adapter 100 are plugged into each other, the third limiting part 411 contacts the second inclined surface 3101 on the socket 310, or the socket 310 contacts the second inclined surface 3101 on the third limiting part 411. The second inclined surface 3101 can play a guiding role, guiding the relative movement between the third limiting part 411 and the socket 310 through the force between them, causing the third limiting member 41 to rotate slightly, and then engaging with the socket 310 through the third limiting part 411. It can be understood that by providing the second inclined surface 3101, it is beneficial for the third limiting member 41 and the socket 310 to achieve the engaging action.

[0071] In one embodiment, the second inclined surface 3101 is disposed at the end of the third limiting part 411. Compared with the socket 310, the third limiting member 41 is smaller, and disposing the second inclined surface 3101 on the third limiting member 41 helps to save the processing and manufacturing cost of the adapter 100.

[0072] In one embodiment, the third limiting assembly 40 further includes a third elastic member 42, which connects the housing 10 and the third limiting member 41. The third elastic member 42 provides a third elastic force to drive the third limiting member 41 to rotate, thereby driving the third limiting portion 411 to rotate toward the position of limiting the connecting socket 310. When the third limiting portion 411 limits the connecting socket 310, the third elastic force provided by the third limiting member 41 helps to improve the stability of the connection between the third limiting member 41 and the socket 310, reducing the risk of separation due to shaking or vibration, and thus improving the stability of the insertion between the adapter 100 and the socket 310.

[0073] Furthermore, by pressing the end of the third limiting member 41 away from the third limiting portion 411, the third limiting member 41 can be driven to rotate in another direction, causing the third limiting portion 411 to separate from the socket 310. At this time, the third limiting member 41 is in the unlocked position, and the adapter 100 can be pulled out of the socket 310 by pulling or unplugging. The part pressed when unlocking the third limiting member 41 and the third limiting portion 411 are located at opposite ends of the rotation axis of the third limiting member 41.

[0074] In one embodiment, the third elastic element 42 is a compression spring or a tension spring. When the third elastic element 42 is a compression spring, the third elastic element 42 and the third limiting portion 411 are located at opposite ends of the rotation axis of the third limiting element 41. When the third elastic element 42 is a tension spring, the third elastic element 42 and the third limiting portion 411 are located at the same end of the rotation axis of the third limiting element 41.

[0075] In one embodiment, the second inclined surface 3101 may not be provided on the adapter 100 or the socket 310. Instead, when the adapter 100 and the socket 310 are plugged in, the end of the third limiting member 41 that is away from the third limiting part 411 is pressed manually. After the two are plugged in, the third limiting member 41 is released, so that the third limiting part 411 rotates to the position of engaging the socket 310 under the action of the third elastic force.

[0076] In summary, when the adapter 100 provided in this application is plugged into the charging gun 200 and the socket 310, the first limiting component 20 is used to limit the connection of the charging gun 200, and the third limiting component 40 is used to limit the connection of the socket 310. This ensures that the charging gun 200 is stably connected to the socket 310 through the adapter 100, guaranteeing the stability of charging the electric vehicle 300. Furthermore, the second limiting component 30 moves to the position where it is limited by the socket 310, restricting the separation action between the adapter 100 and the charging gun 200. After the adapter 100 and the socket 310 are separated, the second limiting component 31 returns to its initial state and separates from the first limiting component 20. At this time, the first limiting component 20 can move relative to the housing 10 to unlock the adapter 100 and the charging gun 200, allowing the adapter 100 and the charging gun 200 to separate from each other. The adapter 100 allows the adapter 100 and the charging gun 200 to be separated only after the connection with the socket 310 is disconnected, realizing "power off first and then unplug the gun". This helps protect the electric vehicle 300 and avoids the risk of damaging the adapter 100 due to forcibly pulling out the charging gun 200, thus extending the service life of the adapter 100.

[0077] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of this application.
