Description

Technical Field

[0001] The utility model belongs to the technical field, and particularly relates to a snap-on charging and discharging plug. Background Art

[0002] To meet their charging and discharging needs, most existing new energy vehicles are equipped with separate charging equipment. This allows users to use the vehicle as a pure electric vehicle, relying solely on charging when other energy sources are inconvenient. These new energy vehicles with charging and discharging functions share a common charging and discharging interface, meaning the same vehicle socket can be used for both charging and discharging. However, existing technologies use two separate charging and discharging devices, each requiring separate use. In particular, existing manufacturers typically only provide charging equipment, while users must purchase their own discharging equipment. Placing two separate devices in the vehicle increases space usage and user costs.

[0003] The existing technology addresses the inconvenience of having to carry two sets of equipment. This involves using a single cable with a detachable connection structure that can be connected to different modules, namely plugs or sockets, thereby achieving both charging and discharging capabilities using the same cable. Because vehicle charging cables employ a detachable structure, connection stability must be considered, particularly for the socket structure used for discharging. Existing sockets often utilize a fixed, integrated plug, cable, and socket structure, lacking detection and control requirements for stable connection and safe power supply, and lacking a corresponding connection structure. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a snap-on charging and discharging plug, which utilizes a snap-on piece provided on the plug and a corresponding trigger module to realize state feedback of a detachable connection with an external socket, thereby achieving a safer connection.

[0005] The technical solution adopted by this utility model is:

[0006] In the first aspect, the utility model provides a snap-on charging and discharging plug for connecting a socket for discharging or a power source for charging, comprising a head and a wire portion, wherein the head has a pin, and the wire portion has a power transmission line conductively connected to the pin. The head is provided with a snap-on connector that is elastically connected to the head and is locked and limited with an external socket, and the snap-on connector also has a button for operation on the head; a trigger module corresponding to the snap-on connector is provided inside the head and is used to connect an external circuit to feedback the activity signal of the snap-on connector.

[0007] It should be noted that the plug referred to in the present invention is a connector connected to other structures through a wire part. The other structures are commonly electrical appliances and sockets, while the plug is used to connect structures with jacks, commonly sockets, but is not limited to a specific current direction. The pins are metal sheets that connect the inner conductors of the jacks of conventional plugs. Common structures are two-pin and three-pin structures, and also include special connection specifications with neutral wire, live wire, and ground wire. The so-called head and wire part are used to refer to the structure of the two parts of the plug. Generally, the two structures are connected in an integrated manner, and the outside is wrapped with an insulating layer for isolation. The wire part is not an independent structure. It is commonly in a state of fixed connection with other structures, and also includes an independent part with a detachable connection with other structures. This utility model does not limit it.

[0008] The head is the main body of the plug, while the pins are mounted on the plug and have two parts, inner and outer. The "clip" is an independent component that is movably connected to the head and is used to achieve a snap connection between the plug and its corresponding connection structure. The so-called button does not specifically require a conventional button form, but rather defines the clip as having an operable end portion that allows the clip to move elastically and constrainedly relative to the connector, thereby achieving snap connection and disconnection with the external socket.

[0009] The so-called trigger module is an independent structure used to externally feedback the activity signal of the card connector. Its feedback circuit is not limited to a specific structure. It can feedback to the device connected by the wire part, or it can be connected to the structure connected by the pin, so as to realize the feedback of the card limit status. The feedback method is electrical signal feedback realized through the cable.

[0010] In combination with the first aspect, the utility model provides a first embodiment of the first aspect, wherein the card connector includes a card pin connected to an external socket, the card pin and the button are independent of each other and the button and the card pin are connected in one-way transmission, and the trigger module is linked to the card pin.

[0011] In combination with the first aspect, the present invention provides a second implementation of the first aspect, wherein the clamping member includes a clamping pin connected to an external socket, and the clamping pin and the button are an integrated structure.

[0012] In combination with the first aspect or several embodiments of the first aspect, the present invention provides a third embodiment of the first aspect, wherein the trigger module has a trigger end corresponding to the clamping member and a signal line arranged in the line portion.

[0013] In combination with the first aspect or several embodiments of the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the trigger module has a trigger end corresponding to the card connector and a signal line, wherein the signal line has a first part located inside the line portion and a second part passing through the head and connected to an external socket.

[0015] In combination with the first or second embodiment of the first aspect, the present invention provides a sixth embodiment of the first aspect, wherein the head comprises an insulating shell, a first opening being provided at one end of the shell and a wire portion having a soft sleeve structure at the opening, wherein the wire portion has a power transmission wire with a connecting pin;

[0016] The shell is further provided with a second opening, and the clamping member is arranged at the second opening and is movably connected to the shell with elastic limitation.

[0017] In combination with the sixth embodiment of the first aspect, the present invention provides a seventh embodiment of the first aspect, wherein the shell has at least two platform structures, wherein one platform has an external pin portion and a clamping pin, and the other platform has a button.

[0018] It should be noted that the external socket that matches the plug of the present invention has a corresponding structure for accommodating a platform, typically a recessed groove. When the prongs of the plug are inserted into the socket, the front portion of the platform with the prongs sinks into the recessed groove, allowing the prongs to engage with the corresponding recessed groove. From the outside, the prongs are hidden during connection, while the button portion remains exposed, facilitating operation.

[0019] The beneficial effects of the utility model are:

[0020] (1) The present invention integrates a card connector and a trigger module for detecting the activity status of the corresponding card connector in the plug, thereby triggering an external detection circuit when the plug is connected to the socket, and can determine in real time whether there is a stable connection, that is, whether the corresponding card connector is actuated, thereby ensuring better connection stability;

[0021] (2) In the present invention, by setting up an appropriate latching part structure and a corresponding feedback method of the trigger module, the object of state detection is determined to be the latching foot part, that is, as long as the latching foot moves, it is determined to be in the state of engagement / disengagement. Compared with the method of detecting the button part, it has higher reliability and specificity. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] It should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. A person of ordinary skill in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] Example 1:

[0035] This embodiment discloses a snap-on charging and discharging plug and a matching plug-in limiter plugging structure.

[0036] It should be noted that the plug in this embodiment can be used in charging and discharging equipment, and can also be used in power supply equipment or current conversion equipment, but is not limited thereto.

[0037] The plug in this embodiment refers to an electrical connection structure commonly used in the art as the male head of a male-female connector. Its typical structure has at least two parts, namely a head and a wire part. The head serves as a plug-in structure for connecting to the outside, and its surface has protruding metal pins 3. The pin 3 structure serves as a connector for the transmission circuit and is used to be inserted into a socket provided on the surface of the plug-in structure to achieve conductivity by connecting to the metal conductor in the socket.

[0038] The wire part has a power transmission line 5, one end of which extends into the head and is connected to the end of the pin 3 inside the head, and the other end extends outward and is connected to an external electrical appliance or socket. This embodiment is not limited to external devices connected to the wire part and is only used for example illustration. In the following content, the wire part is connected to the charging and discharging socket of the vehicle through a charging gun.

[0039] In this embodiment, as an example, the head is used to connect to a discharge power strip with a plug structure. Specifically, the pins 3 are standard three-pin pins 3, and the discharge power strip is provided with a plug structure dedicated to connecting the plug.

[0040] The head section also features an operable clip and a corresponding trigger module 6. The clip forms a flexible, limited connection to the head section. The clip comprises an operable end located on the outer surface of the head section and a clipping portion located on the outer surface of the head section. A slot corresponding to the clipping portion is located next to the socket of the external power strip. The clipping portion is inserted into the slot to achieve positional engagement, while the elastically limited, movable clipping member enables controlled connection and disconnection.

[0041] Among them, a trigger module 6 corresponding to the card connector is provided in the head. The trigger module 6 is connected to the external device and has a trigger end linked with the card connector. When the card connector is actuated, the state of the trigger module 6 is changed through the linked trigger end, thereby sending a feedback signal to the external device to indicate that the card connector is actuated, that is, the connection / disconnection between the plug and the discharge socket strip is achieved.

[0042] The plug-in structure of the discharge power strip in this embodiment includes a three-hole socket and a recessed groove structure around the socket. A slot for accommodating a clamping part is provided on the inner side of the recessed groove. When the plug is partially immersed in the recessed groove, the corresponding clamping part will be controlled to move to form an avoidance space so that it can fall into the corresponding slot to realize the limited connection between the plug and the discharge power strip.

[0043] Furthermore, the clamping member in this embodiment includes a button 2 as an operating end portion and a clamping foot 8 as a clamping portion.

[0044] In one embodiment, the latching pin 8 and button 2 are independent structures, but the latching pin 8 moves with the button 2, while the button 2 does not move with the latching pin 8. The trigger end of the trigger module 6 always maintains a linkage relationship with the latching pin 8, i.e., a contact transmission or non-contact transmission method. In this method, when an external force presses the button 2, the latching pin 8 moves simultaneously, creating an escape space so that the latching pin 8 can fall into the external slot to achieve engagement. When the external force only acts to push the plug into the socket of the power strip without contacting the button 2, the latching pin 8 is actuated by the component force in the pushing direction, and can also fall into the slot and trigger the trigger module 6 to send a signal, thereby improving safety and ensuring that the feedback signal can be stably triggered even when the button 2 is not contacted.

[0045] In another embodiment, the clip is an integrated structure, that is, the clip foot 8 and the button 2 are integrally formed to maintain a fixed connection state. At this time, the trigger mechanism can be set at any position, and it is only necessary to ensure that the trigger end can be linked with any part of the clip.

[0046] Furthermore, trigger module 6 is a switch structure installed in the circuit. It is connected to the external device via signal line 4. Signal line 4 is located in the cable section, that is, it is connected to the charging gun through signal line 4, and is connected to the vehicle through contacts 7 on the charging gun for signal feedback. When the charging gun is connected to the vehicle, if no trigger signal is given to the vehicle at this time, the vehicle will not discharge the external power. However, the trigger module 6 forms a loop with the corresponding circuit on the vehicle end, and the current continues to flow and remains stable. Until the plug is connected to the discharge socket, the trigger module 6 is triggered, causing the current to change, forming a feedback signal that the plug is stable and the vehicle begins discharge detection.

[0047] As another embodiment, the head has a contact 7 with an exposed portion and an internal connection portion, and the trigger module 6 in the head has two signal lines 4, one connected to the internal connection portion of the contact 7, and the other connected to the external vehicle through the line portion. That is, when the charging gun is connected to the vehicle, the circuit in which the trigger module 6 is located does not form a complete loop, and there is no current at this time. It is not until the plug is connected to the discharge power strip that the exposed portion of the contact 7 contacts the corresponding contact 7 of the discharge power strip to form a loop, and current flows, and the trigger module 6 is connected. That is, after the discharge power strip and the plug are stably connected and current flows, the vehicle immediately performs a discharge test, and the presence or absence of current at this time is the feedback signal.

[0048] Further, refer to Figures 1-6 , this embodiment provides a specific implementation scheme.

[0049] The figure shows only the wire part and the head part, in which the head has an insulating shell 1 structure. A first opening is provided on one side of the shell 1 for setting the wire part of the soft tube sleeve structure, and a power transmission line 5 and a signal line 4 are passed through the wire part. A pin 3 is provided on the end face of the head, and the pin 3 is internally connected to the power transmission line 5.

[0050] Reference Figure 3 The housing 1 is provided with a second opening on two symmetrical sides, a spring is provided in the second opening, and a button 2 is connected to the outside of the spring. The spring always pushes the button 2 outward, and the button 2 is installed from the inside of the housing 1 to the outside, and is restricted by the edge of the second opening to keep it in a connected state.

[0051] A trigger module 6 is provided inside the shell 1 corresponding to the button 2 on one side. The trigger module 6 is a mechanical switch structure having a protruding structure toward the inner end of the button 2. When the side button 2 moves inward, the protruding structure can be pushed to connect the circuit inside the trigger module 6.

[0052] Reference Figure 3 A contact 7 is further provided in the middle of the housing 1 , a signal line 4 extending from the trigger module 6 is connected to the contact 7 , and a signal line 4 extending from another point passes through the line portion.

[0053] Reference Figure 2 、 Figure 4 and Figure 5The housing 1 has a two-tiered structure. One tier has the portion with the pins 3 positioned externally and the latching pins 8, while the other tier has the button 2. The power strip that matches the plug has a corresponding recessed groove to accommodate the tier. When the portion of the plug with the pins 3 is inserted into the socket, the tier with the pins 3 at the front sinks into the recessed groove, allowing the latching pins 8 to engage with the corresponding recessed groove. From the outside, the tier with the latching pins 8 is hidden during connection, while the tier with the button 2 remains exposed.

[0054] The present invention is not limited to the above optional embodiments. Anyone can derive various other forms of products based on the inspiration of the present invention. The above specific embodiments should not be construed as limiting the scope of protection of the present invention. The scope of protection of the present invention shall be based on the scope defined in the claims, and the specification can be used to interpret the claims.
