[0032] Embodiment 1:

[0033] This embodiment provides a secondary power connection safety structure for a new energy vehicle discharge product. Figures 1 to 2 As shown, the switch 3 is connected to trigger the conductive connection between the socket 1 and the plug through the insertion of the plug pin and the action of the conductive block 2, so as to solve the problem that the existing new energy vehicle discharge products use the traditional primary power connection method, which is easy to cause the plug or the socket 1 to burn, shorten the service life, and have low safety in use; the secondary power connection safety structure provided in this embodiment includes a socket 1 adapted to the vehicle, and also includes a conductive block 2 and a switch 3 arranged in the socket 1. The conductive block 2 is inserted through the pin to limit the movement relative to the socket 1, and the conductive block 2 is used to connect or disconnect the switch 3 to trigger the conductive connection between the socket 1 and the plug.

[0034] Structure and working principle description:

[0035] Specifically, new energy vehicles in the prior art are usually equipped with a discharge detection circuit, which can not only monitor the current, voltage and other parameters in the discharge process in real time to ensure the stability of the voltage during the discharge process and avoid adverse effects on discharge products and electrical equipment due to voltage fluctuations, but also adjust the discharge strategy according to the real-time status of the battery, such as controlling the discharge current, discharge time, etc., to optimize the discharge process and improve the discharge efficiency. Furthermore, the socket 1 adapted to the vehicle can serve as an interface for connecting to an external device, that is, by electrically connecting the socket 1 to the vehicle and inserting the plug of the external device into the socket 1, the conductive block 2 can perform a limiting activity relative to the socket 1. The conductive block 2, as a key part of the invention, uses the insertion action of the plug pin to move and connect or disconnect the switch 3 to trigger the conductive connection between the discharge detection circuit and the socket 1, thereby achieving a conductive connection between the socket 1 and the plug, so that when the plug is inserted, the socket 1 and the discharge detection circuit are in a connected and conductive state, at which time the socket 1 is energized and can supply power to the external device through the plug; when the plug is pulled out, the socket 1 and the discharge detection circuit are in a disconnected and conductive state, at which time the socket 1 is not energized and cannot supply power to the external device through the plug.

[0036] Understandably, when the plug is fully inserted into the socket 1, the pins of the plug are in contact with the metal bars or sockets in the socket 1 to achieve a first power connection; at the same time, the pins synchronously drive the conduction block 2 to perform a limiting activity relative to the socket 1, so as to connect or disconnect the switch 3 through the conduction block 2 and trigger the conductive connection between the socket 1 and the discharge detection circuit, thereby realizing the second power connection between the socket 1 and the discharge detection circuit. Obviously, the socket 1 will only be charged after the discharge detection circuit completes the discharge detection and delivers electrical energy to the socket 1. At this time, the pins of the plug are already in contact with the metal bars or sockets in the socket 1, which can avoid the generation of electric sparks at the pins of the plug and the metal bars or sockets in the socket 1, effectively prevent the pins of the plug or the metal bars and sockets in the socket 1 from being corroded by high temperature due to electric sparks and causing burnout, not only extending the service life of the plug and the socket 1, but also preventing the plug from having poor contact or loose virtual connection with the socket 1 due to the burnout of the pins, ensuring the safety of the vehicle during the discharge process, effectively avoiding potential safety hazards caused by improper user operation, and improving the use safety.

[0037] It is worth noting that in order to ensure that the pins can smoothly contact the conduction block 2 and improve the smoothness of the movement of the conduction block 2, in the actual production and manufacturing of the present utility model, inclined platforms 9 are formed on the bottom surface of the conduction block 2 corresponding to the positions of the ground wire, live wire and neutral wire pins. The inclined platforms 9 are inclined from one side edge of the conduction block 2 towards the direction away from the panel of the socket 1, and through holes for the inclined platforms 9 to pass through are provided on the socket 1 corresponding to the positions of the ground wire, live wire and neutral wire pins, so as to meet the requirement that when the plug is inserted, the pins of the plug can contact the conduction block 2, that is, when a three-pin plug is inserted, the ground wire pin of the three-pin plug contacts the inclined platform 9 at the middle position on the bottom surface of the conduction block 2, so that the conduction block 2 can move along with the insertion of the plug; similarly, when a two-pin plug is inserted, the live wire pin and the ground wire pin of the two-pin plug contact the inclined platforms 9 at both sides on the bottom surface of the conduction block 2, and thus the conduction block 2 can also move along with the insertion of the plug. The structural design is ingenious and reasonable.

[0038] Embodiment 2:

[0039] On the basis of Embodiment 1, this embodiment further combines the attached drawings of the specification Figures 1 to 2 As shown. The secondary power connection safety structure of a new energy vehicle discharge product of the present utility model further includes a pressing block 4 in contact with the conduction block 2. A contact point 5 is provided on the switch 3. The pressing block 4 is installed in the socket 1 in a limited movement manner through the conduction block 2 and is used to contact or separate from the contact point 5; and an elastic member 6 is further provided in the socket 1, and the elastic member 6 is located between the pressing block 4 and the contact point 5.

[0040] Specifically, the installation method of the briquette 4 and the socket 1 with limited movement can adopt a sliding snap connection, that is, slots are respectively opened on both sides of the socket 1 corresponding to the contacts 5. The slots extend along the insertion direction of the plug, and protrusions that are in sliding contact and cooperation with the slots are respectively formed on both sides of the briquette 4. Thus, the installation limit of the briquette 4 on the socket 1 can be realized, enabling the briquette 4 to move smoothly and smoothly in the slots relative to the socket 1. The structural design is simple and reasonable.

[0041] It can be understood that when the plug is inserted into the socket 1, the pins of the plug abut against the conduction block 2 and push the conduction block 2 to abut against the briquette 4. As the pins continue to penetrate, the pins finally abut against the socket or metal guide bar in the socket 1 to achieve the primary power connection between the plug and the socket 1; at the same time, the plug can synchronously push the briquette 4 to move relative to the socket 1 and press the contact 5 through the briquette 4. At this time, the elastic member 6 is in a compressed state, so that the switch 3 can be connected and the conductive connection between the socket 1 and the discharge detection circuit can be triggered, realizing the secondary power connection between the socket 1 and the discharge detection circuit. Thus, it can avoid the generation of electric sparks at the pins of the plug and the metal guide bar or socket in the socket 1, not only extending the service life of the plug and the socket 1, but also ensuring the safety of the vehicle during the discharge process, effectively avoiding potential safety hazards caused by improper user operation and improving the use safety. In addition, when the plug is pulled out, at this time, the briquette 4 and the conduction block 2 lose the abutment limit of the pins, and under the rebound action of the elastic member 6, the briquette 4 and the conduction block 2 move away from the switch 3, thereby causing the contact 5 on the switch 3 to automatically reset. Thus, the conductive connection between the socket 1 and the discharge detection circuit can be disconnected, that is, the secondary power connection between the socket 1 and the discharge detection circuit is disconnected. At this time, the socket 1 is in a non-powered state, effectively preventing the electric shock risk caused by accidental touch or accidental short circuit, playing a crucial safety protection for users, maintenance personnel and the surrounding environment, and greatly improving the use safety of the vehicle discharge system. It is worth noting that inclined platforms 9 are respectively formed on the top surface of the conduction block 2 and the bottom surface of the briquette 4, so as to improve the stability when the conduction block 2 abuts against the briquette 4 and ensure that the briquette 4 can move smoothly and smoothly relative to the socket 1 under the push of the conduction block 2.

[0042] Embodiment 3:

[0043] Based on Embodiment 1, this embodiment further combines the attached drawings of the specification Figure 3 as shown. The purpose of this embodiment is to provide another structural layout to realize the connection or disconnection of the switch 3 by moving the conduction block 2 and trigger the conductive connection between the socket 1 and the discharge detection line. Specifically, a contact 5 is provided on the bottom surface of the switch 3, and elastic members 6 are respectively provided on both sides of the switch 3. The conduction block 2 is inserted or pulled out through the pins to abut against or separate from the contact 5.

[0044] In this embodiment, by arranging the contact 5 on the bottom surface of the switch 3, the contact 5 faces the conduction block 2, and the conduction block 2 is limited to move along the height direction of the socket 1. When the plug is inserted into the socket 1, the pin pushes the conduction block 2 to move upward. At this time, the elastic member 6 is in a compressed state, so that the conduction block 2 can directly press the contact 5, thereby connecting the switch 3 and realizing the electrical connection between the socket 1 and the discharge detection circuit. The structural design is simple and reasonable. The difference between this embodiment and Embodiment 2 is that this embodiment does not require the installation of the pressing block 4, thereby simplifying the overall structure, omitting the assembly step of installing the pressing block 4, avoiding the assembly gap, eliminating the assembly error, and saving the production cost. It should be noted that when the plug is pulled out, the conduction block 2 loses the abutting limit of the pin, and the elastic members 6 on both sides of the switch 3 rebound, so that the conduction block 2 can move downward and separate from the switch 3. At this time, the contact 5 resets, thereby disconnecting the electrical connection between the socket 1 and the discharge detection circuit, and further making the socket 1 in a non-powered state when the plug is not inserted, effectively preventing the electric shock risk caused by accidental touch or accidental short circuit, and improving the use safety of the vehicle discharge system.

[0045] Embodiment 4:

[0046] On the basis of Embodiment 1, this embodiment further combines the attached drawings of the specification Figure 4 as shown. The purpose of this embodiment is to provide another structural layout to realize the connection or disconnection of the switch 3 by moving the conduction block 2 and trigger the electrical connection between the socket 1 and the discharge detection circuit. Specifically, the switch 3 includes a stationary contact 7 and a movable contact 8 that are electrically connected to the discharge detection circuit of the vehicle end. The stationary contact 7 is fixedly installed in the socket 1. The movable contact 8 extends and bends toward the conduction block 2. Elastic members 6 are respectively arranged on both sides of the movable contact 8, and the movable contact 8 is limited to move relative to the socket 1 through the conduction block 2 to abut against the stationary contact 7.

[0047] In this embodiment, the static blade 7 is fixedly installed in the socket 1, and one end of the moving blade 8 is fixedly installed in the socket 1, so that one end of the static blade 7 and the moving blade 8 can be stably electrically connected to the discharge detection circuit at the vehicle end. Further, since one end of the moving blade 8 extends and bends towards the conduction block 2, and the conduction block 2 is installed in the socket 1 with limited movement along the height direction of the socket 1, when the plug is inserted into the socket 1, the pin pushes the conduction block 2 upward and makes the conduction block 2 abut against the moving blade 8. As the pin continuously penetrates, the elastic member 6 gradually tends to be in a compressed state, and the conduction block 2 can press the moving blade 8 upward so that the other end of the moving blade 8 abuts against the other end of the static blade 7, thereby connecting the static blade 7 and the moving blade 8, and further realizing the conduction of the discharge detection circuit. At this time, the discharge detection circuit can perform discharge detection and transmit electric energy to the socket 1, and the structural design is simple and reasonable. In addition, when the plug is pulled out, the conduction block 2 loses the abutment limit of the pin, and the elastic members 6 on both sides of the switch 3 rebound, so that the conduction block 2 can move downward to separate the moving blade 8 and the static blade 7, thereby disconnecting the conductive connection between the switch 3 and the socket 1 and the discharge detection circuit, making the socket 1 in a non-powered state when the plug is not inserted, effectively preventing the electric shock risk caused by accidental touch or accidental short circuit, and improving the use safety of the vehicle discharge system.

[0048] It is worth noting that during the production and manufacturing process of this embodiment, a protrusion is formed on the top surface of the conduction block 2, and the protrusion abuts against the moving blade 8, so as to ensure that when the plug is inserted, the conduction block 2 can drive the moving blade 8 to stably abut against the static blade 7 under the push of the pin, and the use is reliable.

[0049] Embodiment 5:

[0050] On the basis of Embodiment 1, this embodiment further combines the attached drawings of the specification Figure 5 as shown. The purpose of this embodiment is to provide another structural layout to realize the connection or disconnection of the switch 3 by moving the conduction block 2 and trigger the conductive connection between the socket 1 and the discharge detection circuit. Specifically, a contact 5 is arranged on one side of the switch 3, two elastic members 6 are arranged at intervals along the extension direction of the top surface of the conduction block 2, and a ramp 9 is formed between the two elastic members 6. The ramp 9 abuts against or separates from the contact 5 by inserting or pulling out the pin.

[0051] In this embodiment, a bevel 9 is formed on the top surface of the conduction block 2. When the plug is inserted into the socket 1, the pins of the plug push the conduction block 2 to move upward, and the bevel 9 on the conduction block 2 abuts against the contact 5. As the pins go deeper, the bevel 9 can press the contact 5, thereby connecting the switch 3 to trigger the conductive connection between the socket 1 and the discharge detection circuit. It can be understood that the difference between this embodiment and Embodiment 2 and Embodiment 3 is that in this embodiment, the pressing block 4 and the conduction block 2 are made into an integral structure, which can omit the assembly step of installing the pressing block 4, is easy to manufacture, and is conducive to maintenance and replacement. In addition, when the plug is pulled out, the conduction block 2 loses the abutting limit of the pins, and the elastic members 6 on both sides of the bevel 9 rebound, so that the conduction block 2 can move downward to separate the bevel 9 and the contact 5, thereby disconnecting the switch 3 and the conductive connection between the socket 1 and the discharge detection circuit, making the socket 1 in a non-powered state when the plug is not inserted, effectively preventing the electric shock risk caused by accidental touch or accidental short circuit, and improving the use safety of the vehicle discharge system.

[0052] Embodiment 6:

[0053] On the basis of Embodiment 1, this embodiment further combines the attached drawings of the specification Figure 6 and Figure 7 as shown. The purpose of this embodiment is to provide another structural layout to realize the connection or disconnection of the switch 3 by moving the conduction block 2 and trigger the conductive connection between the socket 1 and the discharge detection circuit. Specifically, a contact 5 is arranged on one side of the switch 3, a pressure rod 10 is arranged in the socket 1, the pressure rod 10 is detachably connected to the conduction block 2, the pressure rod 10 is inserted or pulled out by the pins to rotate relative to the socket 1 and abut against or separate from the contact 5, and an elastic member 6 is arranged between the pressure rod 10 and the socket 1.

[0054] In this embodiment, a pressure rod 10 is rotatably installed in the socket 1, and one end of the pressure rod 10 is detachably connected to the conduction block 2. When the plug is inserted into the socket 1, the pins abut against the conduction block 2 and push the conduction block 2 upward. At this time, the elastic member 6 is in a compressed state, and at the same time, one end of the pressure rod 10 is pushed to rotate upward relative to the other end. According to the lever principle, the other end of the pressure rod 10 can move downward and press the contact 5 of the switch 3, thereby connecting the switch 3 and the conductive connection between the socket 1 and the discharge detection circuit. The structural design is ingenious and reasonable; at the same time, when the plug is pulled out, the conduction block 2 loses the abutting limit of the pins, and the elastic member 6 arranged between the pressure rod 10 and the socket 1 rebounds, and then presses one end of the pressure rod 10 downward, so that the other end of the pressure rod 10 separates from the contact 5, thereby disconnecting the switch 3 and the conductive connection between the socket 1 and the discharge detection circuit, making the socket 1 in a non-powered state when the plug is not inserted, effectively preventing the electric shock risk caused by accidental touch or accidental short circuit, and improving the use safety of the vehicle discharge system.

[0055] Embodiment 7:

[0056] This embodiment is further improved on the basis of Embodiments 1 to 6. The switch 3 is used to be electrically connected to the discharge detection circuit at the vehicle end. Specifically, the connection or disconnection of the switch 3 can be achieved through Embodiments 1 to 6, and the conduction of the discharge detection circuit at the vehicle end can be achieved through the connection or disconnection of the switch 3, so as to achieve the conduction or disconnection of the socket 1 and the discharge detection circuit, that is, the secondary connection between the socket 1 and the discharge detection circuit, thereby avoiding the generation of electric sparks at the pin and the metal guide bar or socket, prolonging the service life of the plug and the socket 1, and improving the use safety.

[0057] Embodiment 8:

[0058] This embodiment is further improved on the basis of Embodiments 1 to 6. An isolation circuit electrically connected to the detection circuit at the vehicle end is provided in the socket 1, and the switch 3 is used to trigger the on-off of the isolation circuit. Specifically, the socket 1 is electrically connected through the isolation circuit, so that the discharge detection circuit can supply electric energy to the socket 1. Further, the connection or disconnection of the switch 3 can be achieved through Embodiments 1 to 6, and the on-off of the isolation circuit can be achieved through the switch 3. It can be seen that when the plug is inserted into the socket 1, the switch 3 is connected to trigger the conduction of the isolation circuit, so that the discharge detection circuit can supply power to the socket 1 and discharge to the external load; on the contrary, after the plug is pulled out, the switch 3 triggers the isolation circuit to disconnect, thereby cutting off the current path inside the socket 1 and improving the use safety. It is worth noting that in this embodiment, by adding an isolation circuit, the discharge detection circuit can work in a more stable and pure electrical environment, which not only helps to reduce the detection error caused by external electrical interference, improves the measurement accuracy of the discharge detection circuit for parameters such as current and voltage, but also provides more flexibility and scalability for the vehicle discharge system. For example, the parameters or structure of the isolation circuit can be adjusted to adapt to different types of external loads or discharge requirements.

[0059] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
