Technical Field

[0001] This application relates to the field of socket technology, and more particularly to a socket, a plug-in assembly, a power transmission device, and a vehicle. Background Technology

[0002] In related technologies, sockets are equipped with triggers and circuit switches. The triggers are only used to control the opening and closing of the circuit switches, which makes the function of the triggers relatively simple. Utility Model Content

[0003] This application provides a socket, a plug-in assembly, a power transmission device, and a vehicle, aiming to enrich the functionality of triggering elements.

[0004] To achieve the above objectives, according to a first aspect of this application, a socket is provided, comprising:

[0005] A connector for plugging in a plug;

[0006] A circuit switch is installed in the socket;

[0007] A locking structure has a locked state and an unlocked state. When the locking structure is in the locked state, it restricts the separation of the socket and the plug. When the locking structure is in the unlocked state, it releases the restriction on the separation of the socket and the plug.

[0008] The trigger is used to control the opening and closing of the circuit switch, and also to control the locking structure to switch between the locked state and the unlocked state.

[0009] Optionally, the circuit switch has a closed state and an open state. When the trigger controls the circuit switch to enter the closed state, the locking structure enters the locking state. When the trigger controls the circuit switch to enter the open state, the locking structure enters the unlocking state.

[0010] Optionally, the socket further includes a functional circuit, which is activated through the plug when the circuit switch is closed and the plug is inserted into the socket.

[0011] Optionally, the trigger can move along a first direction to drive the locking structure into the locking state. The locking structure has a guide surface, which is inclined in the first direction. The trigger slides on the guide surface to drive the locking structure into the locking state.

[0012] Optionally, during the movement of the trigger in a direction opposite to the first direction, the locking structure switches from the locked state to the unlocked state.

[0013] Optionally, the socket further includes a first elastic element that connects the locking structure and the socket, the first elastic element causing the locking structure to tend to remain in the unlocked state.

[0014] Optionally, the socket further includes a guide member disposed on the plug socket, the guide member extending along the first direction, and the trigger member slidingly engaging with the guide member.

[0015] Optionally, the trigger has a first state that causes the locking structure to enter the locking state, and the trigger has a tendency to remain in the first state.

[0016] Optionally, the socket further includes a second elastic element that connects the trigger and the socket, the second elastic element having a tendency to maintain the trigger in the first state.

[0017] Optionally, the socket has a slot and a socket on the bottom wall of the slot. The slot is for the plug socket of the plug to be inserted into, and the socket is for the plug pins of the plug to be inserted into. The locking structure has a locking end. When the locking structure is in the locked state, the locking end extends into the slot. The locking end is used to restrict the socket and the plug from separating.

[0018] Optionally, the locking structure is rotatably connected to the plug-in socket;

[0019] And / or, and / or, the trigger is configured as a self-locking switch.

[0020] Optionally, the locking structure is provided in multiple ways, and the locking structure has a locking end. In the locked state, the locking end is used to restrict the separation of the socket and the plug. During the process of two locking structures entering the locked state, the two locking ends approach each other.

[0021] According to a second aspect of this application, a plug-in assembly is provided, comprising:

[0022] The aforementioned socket; and

[0023] A plug for connecting to the socket.

[0031] In the socket of this application embodiment, the trigger element not only serves as a component for controlling the opening and closing of the circuit switch, but also is reused as a component for controlling the switching of the locking structure between the locked state and the unlocked state. This makes the trigger element serve two purposes, enriches the function of the trigger element, and is conducive to simplifying the socket structure.

Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0050] According to the first aspect of this application, referring to Figures 1 to 12This disclosure provides a socket 100, which includes a socket 200, a circuit switch 500, a locking structure 300, and a trigger 400. The socket 200 is used for plugging into a plug 600. The circuit switch 500 is mounted on the socket 200. The locking structure 300 has a locked state and an unlocked state. When the locking structure 300 is in the locked state, it restricts the separation of the socket 200 and the plug 600. When the locking structure 300 is in the unlocked state, it releases the restriction on the separation of the socket 200 and the plug 600. The trigger 400 is used to control the opening and closing of the circuit switch 500 and also to control the switching of the locking structure 300 between the locked and unlocked states.

[0051] The trigger 400 not only serves as a component for controlling the opening and closing of the circuit switch 500, but also serves as a component for controlling the switching of the locking structure 300 between the locked and unlocked states. This makes the trigger 400 serve two purposes, enriching its functions and contributing to the simplification of the socket 100 structure.

[0052] Furthermore, when the plug 600 of a traditional socket 100 is unplugged while energized, it may generate an electric spark, potentially causing electric shock or damage to electrical equipment. In this design, the locking structure 300 prevents the socket 200 and plug 600 from separating when locked. The plug 600 can only be unplugged when the trigger 400 controls the locking structure 300 to switch to the unlocked state. This effectively prevents the plug 600 from being accidentally unplugged while energized, greatly improving the safety of the socket 100.

[0053] In some embodiments, the circuit switch 500 has a closed state and an open state. When the trigger 400 controls the circuit switch 500 to enter the closed state, the locking structure 300 enters the locking state. When the trigger 400 controls the circuit switch 500 to enter the open state, the locking structure 300 enters the unlocking state.

[0054] Users do not need to manually operate the locking structure 300; they only need to control the opening and closing of the circuit switch 500 via the trigger 400. The locking structure 300 will automatically switch to the corresponding locking or unlocking state according to the state of the circuit switch 500. This automatic matching design simplifies the operation process. Users only need to focus on the on / off state of the circuit, and the socket 100 will automatically complete the corresponding locking or unlocking action, making it more convenient to use.

[0055] In some embodiments, the socket 100 further includes a functional circuit that is powered on through the plug 600 when the circuit switch 500 is closed and the plug 600 is plugged into the socket 200.

[0056] In one example, there are two functional circuits: a detection signal circuit and a connection confirmation signal circuit. The detection signal circuit includes a detection signal probe 730, and the connection confirmation signal circuit includes a connection confirmation signal probe 740. When the circuit switch 500 is closed and the plug 600 is plugged into the socket 200, the PE line of the plug 600 is connected to the detection signal probe 730 and the connection confirmation signal probe 740. This makes the detection signal circuit, the connection confirmation signal circuit, and the PE line form a signal loop, thereby enabling the socket 100 to supply power to the plug 600.

[0057] In some embodiments, the trigger 400 can move along a first direction to drive the locking structure 300 into a locking state. The locking structure 300 is provided with a guide surface 310, which is inclined in the first direction. The trigger 400 drives the locking structure 300 into a locking state by sliding on the guide surface 310.

[0058] It is understandable that the pose of the locking structure 300 when it is in the locked state is different from that when it is in the unlocked state. During the process of the trigger 400 sliding on the guide surface 310, the relative pose of the trigger 400 and the guide surface 310 changes, so that the pose of the locking structure 300 changes during the movement of the trigger 400 along the first direction, thereby enabling the locking structure 300 to enter the locked state.

[0059] The trigger 400 drives the locking structure 300 by sliding on the guide surface 310, which saves the complex structure to realize the transmission between the trigger 400 and the locking structure 300.

[0060] In one example, the locking structure 300 is rotatably connected to the socket 200. In another example, the locking structure 300 is slidably connected to the socket 200, and the sliding direction of the locking structure 300 is a first sliding direction. It can be understood that the first sliding direction intersects with the first direction.

[0061] In some embodiments, as the trigger 400 moves in a direction opposite to the first direction, the locking structure 300 switches from a locked state to an unlocked state.

[0062] This design allows users to unlock the locking structure 300 by a simple reverse operation (the trigger 400 moves in the opposite direction to the first direction), thus putting the locking structure 300 into the unlocked state and ensuring the reversibility of the operation. Users can unlock it without additional tools or complicated operations, improving ease of use.

[0063] There are many ways to achieve the switching of the locking structure 300 from the locked state to the unlocked state during the movement of the trigger 400 in the opposite direction to the first direction. In some embodiments, the socket 100 also includes a first elastic member 710, which connects the locking structure 300 and the plug socket 200. The first elastic member 710 gives the locking structure 300 a tendency to remain in the unlocked state.

[0064] However, this design is not limited to this. In some other embodiments, the socket 100 also includes a first magnetic element, which is disposed on the plug socket 200 and is used to magnetically connect with the locking structure 300. The first magnetic element causes the locking structure 300 to tend to remain in the unlocked state; or, the locking structure 300 tends to remain in the unlocked state by its own weight.

[0065] In some embodiments, the first elastic element 710 is configured as a tension spring or a compression spring.

[0066] In some embodiments, the socket 100 further includes a guide 750 disposed on the plug socket 200, the guide 750 extending along a first direction, and the trigger 400 slidingly engaging with the guide 750.

[0067] The trigger 400 and the guide 750 slide together to ensure that the trigger 400 moves stably along a predetermined trajectory during operation, avoiding misoperation caused by the shaking or deviation of the trigger 400.

[0068] In some embodiments, the trigger 400 has a first state that causes the locking structure 300 to enter a locking state, and the trigger 400 has a tendency to remain in the first state.

[0069] In this way, the trigger 400 can be maintained in the first state relatively stably, which in turn allows the locking structure 300 to be maintained in the locked state relatively stably, thereby enabling the plug 600 and the socket 200 to be connected relatively stably.

[0070] There are many ways to make the trigger 400 tend to maintain a first state. In some embodiments, the socket 100 further includes a second elastic member 720, which connects the trigger 400 and the socket 200 and has a tendency to keep the trigger 400 in the first state.

[0071] However, this design is not limited to this. In some other embodiments, the socket 100 also includes a second magnetic element, which is disposed in the plug socket 200 and is used to magnetically connect with the trigger 400. The second magnetic element causes the trigger 400 to tend to remain in the first state; or, the trigger 400 tends to remain in the first state by its own weight.

[0072] The locking structure 300 can be installed in many locations. In some embodiments, the socket 200 is provided with a slot 211 and a socket 212 provided on the bottom wall of the slot 211. The slot 211 is used for the plug socket 610 of the plug 600 to be inserted, and the socket 212 is used for the plug pin 620 of the plug 600 to be inserted. The locking structure 300 has a locking end 430. When the locking structure 300 is in the locked state, the locking end 430 extends into the slot 211. The locking end 430 is used to restrict the socket 200 and the plug 600 from separating.

[0073] However, this design is not limited to this. In some other embodiments, the relative positional relationship between the locking structure 300 and the plug 200 can also be other, as long as the locking structure 300 has a locking state and an unlocking state, the locking state is used to restrict the separation of the plug 200 and the plug 600, and the unlocking state is used to release the restriction on the separation of the plug 200 and the plug 600.

[0074] There are many ways to connect the locking structure 300 and the plug-in socket 200. In some embodiments, the locking structure 300 and the plug-in socket 200 are rotatably connected. However, this design is not limited to this. In some other embodiments, the locking structure 300 and the plug-in socket 200 are slidably connected.

[0075] In some embodiments, the trigger 400 is configured as a self-locking switch. A self-locking switch is a switching device that automatically locks in a pressed state after being activated, and does not automatically spring back after being released; it requires activation again to unlock and return to its initial state. There are many types of self-locking switches, including, but not limited to, the push-button self-locking switch for a pen or a trash can, as described in related technologies; these will not be elaborated upon further here.

[0076] In some embodiments, multiple locking structures 300 are provided. Even if one locking structure 300 fails or is affected by external force, the other locking structures 300 can still be used, thereby effectively preventing the plug 600 from accidentally loosening or falling off relative to the socket 100.

[0077] In some embodiments, the locking structure 300 has a locking end 430, which, in the locked state, restricts the separation of the socket 200 and the plug 600. During the locking process, the two locking ends 430 approach each other. This increases the difficulty for the plug 600 to disengage from the socket 100.

[0078] According to a second aspect of this disclosure, a plug-in assembly is provided, comprising a plug 600 and the aforementioned socket 100. This plug-in assembly possesses all the beneficial effects of the aforementioned socket 100, which will not be elaborated further herein. The plug 600 is used for plugging into the socket 100.

[0079] According to a third aspect of this disclosure, a power transmission device is provided, comprising a discharge gun and the aforementioned plug-in assembly. This power transmission device possesses all the beneficial effects of the aforementioned plug-in assembly, which will not be elaborated further herein.

[0080] According to a fourth aspect of this disclosure, a vehicle is provided that includes the aforementioned socket 100, or the aforementioned plug-in assembly, or the aforementioned power transmission device. The vehicle possesses all the beneficial effects of the aforementioned socket 100, or all the beneficial effects of the aforementioned plug-in assembly, or all the beneficial effects of the aforementioned power transmission device, as will not be elaborated upon herein.

[0081] In one example, the vehicle includes a vehicle body, a socket 100 located on the vehicle body, and a discharge gun connection plug 600. The discharge gun is connected to the socket 100 via the plug 600 so that the vehicle body can discharge to the outside via the discharge gun.

[0082] When the circuit switch 500 is in the open state, the trigger 400 has a trigger end 410 for driving the two locking structures 300. The trigger end 410 is in contact with the guide surface 310 of the locking structure 300, and the locking structure 300 is subjected to the tension of the tension spring, causing the locking end 430 to exit the slot 211.

[0083] When the trigger 400 is pressed, the trigger end 410 moves downward, and the locking structure 300 is pushed laterally by the component force of the guide surface 310. The trigger 400 presses against the circuit switch 500, thereby closing the circuit switch 500. Furthermore, the locking structure 300 is also provided with a stop surface 320. In the first direction, the second guide surface 310 and the stop surface 320 are sequentially arranged, and the second guide surface 310 is connected to the stop surface 320, which extends along the first direction. In the first state, the trigger 400 abuts against the stop surface 320 to prevent the locking structure 300 from exiting the first locking state. The trigger end 410 presses against the stop surface 320 to keep the locking structure 300 locked. The second elastic member 720 provides pressure to keep the trigger 400 from moving in the first direction. The locking structure 300 is connected to the plug socket 200 through the pivot 760. The locking structure 300 rotates around the pivot 760 so that the locking end 430 enters the slot 211.

[0084] When the locking structure 300 is in the unlocked state, it is not engaged in the slot 211 due to the force of the tension spring, and the plug 600 can be freely inserted and removed. Under the drive of the trigger 400, the circuit switch 500 is closed, and the locking structure 300 is pushed by the trigger 400, rotating around the pivot 760. The locking end 430 enters the slot 211 to cooperate with the locking groove 611 of the plug 600, making it difficult for the plug 600 to separate from the socket 100.

[0085] When plug 600 is not plugged into socket 200, if circuit switch 500 is closed and locking structure 300 is engaged under the drive of trigger 400, plug 600 will be unable to plug into socket 200 because the locking end 430 of locking structure 300 extends into slot 211. The metal pins on plug 600 will not be able to contact the detection signal probe 730 and connection confirmation signal probe 740 of socket 100, preventing socket 100 from discharging to plug 600.

[0086] In another example, the connector 200 includes a first cover 210 and a second cover 220. The first cover 210 is provided with a slot 211 and a socket 212. The first spring can be configured as a compression spring, which is arranged between the locking structure 300 and the inner wall of the first cover 210. When the trigger 400 pushes the locking structure 300 to rotate in a first direction, the compression spring is compressed. When the trigger 400 moves in a direction opposite to the first direction, the compression force of the compression spring resets the locking structure 300. After power is cut off, the plug 600 can be freely inserted and removed.

[0087] It is worth mentioning that when the detection signal circuit and the connection confirmation signal circuit are turned on through the plug 600, the vehicle can discharge to the discharge gun through the socket 100 and the plug 600.
