[0031] With the industrialization and rapid popularization of electric vehicles, electric vehicles not only fulfill the function of charging but also enable external discharge. In some outdoor scenarios, connecting a dedicated discharge gun to the vehicle's power battery charging interface to discharge power to 220V electrical appliances has become a common application. Different countries may use different plug and socket standards. If each discharge gun is molded separately, it will result in wasted costs, increased management costs, and a higher failure rate.
[0032] See also Figure 1 and Figure 2 See Figure 1 , Figure 1 A schematic diagram of the discharge gun in one embodiment of this application is shown. Figure 2 A first exploded view of a discharge gun in one embodiment is shown. An embodiment of the discharge gun provided in this application includes a housing 10, a socket assembly 30, and a connector 20. The housing 10 has an internal accommodating space capable of accommodating electronic components, and the housing 10 can shield the internal electrical components, providing protection. The connector 20 is used to connect to a vehicle and is electrically connected to the vehicle's internal battery, and is also electrically connected to the socket assembly 30. The socket assembly 30 is used to connect external electrical devices so that the vehicle's internal battery can supply power to the external devices.
[0033] Specifically, the housing 10 contains a terminal assembly 11, which electrically connects the socket assembly 30 and the connector 20. The terminal assembly 11 is designed to ensure the reliability and safety of the electrical connection, preventing current leakage or short circuits. The socket assembly 30 is used to connect external electrical equipment. The socket assembly 30 is detachably disposed at the first end of the housing 10 and electrically connected to the first end of the terminal assembly 11. Exemplarily, the external electrical equipment may be a battery, power bank, refrigerator, power tool, portable appliance, etc. The socket assembly 30 is detachably connected to the housing 10, allowing for replacement of the socket assembly 30. In one feasible implementation, the socket assembly 30 is connected to the housing 10 by screws or bolts 22. In another feasible implementation, the socket assembly 30 is snap-fitted into the housing 10.
[0034] The connector 20 is used to connect to a vehicle, such as to the vehicle's battery. The connector 20 is detachably mounted on the second end of the housing 10. This detachable connection facilitates replacement, allowing the specifications of the connector 20 to be determined based on the vehicle's discharge port when switching between different vehicles. Furthermore, the detachable design of the connector 20 facilitates maintenance or replacement in case of damage. The connector 20 is electrically connected to the second end of the terminal assembly 11, thus enabling an electrical connection between the connector 20 and the socket assembly 30 via the terminal assembly 11.
[0035] In the aforementioned discharge gun, the housing 10 has a terminal assembly 11 inside. A socket assembly 30 is detachably connected to the first end of the housing 10, and a connector 20 is detachably connected to the second end of the housing 10. The socket assembly 30 and the connector 20 are electrically connected via the terminal assembly 11. Thus, when the connector 20 is connected to a vehicle, an electrical connection is established between the socket assembly 30 and the vehicle's power supply. When the socket assembly 30 is connected to an external electrical device, discharge can be transmitted from the vehicle to the external device. Specifically, in this application, the socket assembly 30 is detachably connected to the housing 10, allowing for the installation of multiple sockets suitable for different standards. Therefore, in different application scenarios, only the socket assembly 30 needs to be replaced.
[0036] In some embodiments, the socket assembly 30 is any one of a German standard socket, a British standard socket, or a French standard socket. A German standard socket refers to a socket conforming to the German standard, typically with round sockets, using the "Schuko" design, featuring two grounding pins, suitable for 230V voltage, and a maximum current of 16A. A British standard socket refers to a socket conforming to the British standard, using rectangular sockets with three parallel pins, conforming to BS 1363 standard, supporting 230V voltage, a maximum current of 13A, and equipped with fuse protection. A French standard socket refers to a socket conforming to the French standard, using round sockets, but unlike the German standard, it includes two round sockets and one grounding pin, conforming to NF C 61-314 standard, supporting 230V voltage, and a maximum current of 16A.
[0037] Thus, when the electrical equipment is of German standard, a German standard socket can be used and connected to the housing 10; when the electrical equipment is of British standard, a British standard socket can be connected to the housing 10; when the electrical equipment is of French standard, a French standard socket can be connected to the housing 10. At the same time, the connector 20 is connected to the car, thus realizing the electrical connection between the car power supply and the socket, making the car and the electrical equipment electrically connected, and thus supplying power to the electrical equipment.
[0038] In this embodiment, the socket assembly 30 can be replaced according to the application scenario of the electrical equipment, so that the socket assembly 30 is consistent with the standard adopted by the electrical equipment, thereby making it feasible to discharge the electrical equipment through the car.
[0039] To provide users with clear usage scenario guidance, the housing 10 is designed with fitted warning elements 12, which are printed with important warning information. The purpose of these warnings is to ensure that users understand and follow necessary safety regulations when operating the equipment, thereby avoiding potential usage risks.
[0040] Optionally, the warning information may include: rated voltage, maximum voltage, etc., reminding the user of the maximum voltage limit that the equipment can withstand, thereby preventing accidental exceedance of this voltage range during operation and avoiding potential equipment damage or electrical safety hazards. Warning element 12 may also contain other important safety tips, such as operating precautions, maintenance recommendations, and emergency response procedures.
[0041] See Figure 3 , Figure 3 A second exploded view of the discharge gun in one embodiment is shown. In one embodiment, the socket assembly 30 includes a first sub-housing 31 and a first wiring portion 32. The first sub-housing 31 is detachably connected to a first end of the housing 10. When the first sub-housing 31 is connected to the housing 10, the first wiring portion 32 is electrically connected to the terminal assembly 11.
[0042] The socket assembly 30 is designed with several key components to ensure its functionality and safety. Specifically, the socket assembly 30 includes the following parts: First sub-housing 31: This is the main housing part of the socket assembly 30, designed to be detachably connected to the first end of the housing 10. The main function of the first sub-housing 31 is to provide structural support and protect the internal electrical components from external environmental influences. First wiring section 32 is responsible for connecting cables or wires to the terminal assembly 11, ensuring a stable current flow. When the first sub-housing 31 is connected to the first end of the housing 10, the first wiring section 32 establishes an effective electrical connection with the terminal assembly 11, enabling the socket assembly 30 to operate normally. This design not only improves the safety and stability of the socket but also facilitates maintenance and replacement operations.
[0043] In some embodiments, the terminal assembly 11 includes a plurality of power terminals 111 and a limiting member 112. The plurality of power terminals 111 extend into the limiting member 112 and are limited by the limiting member 112. The power terminals 111 are used for electrical connection between the connector 20 and the socket assembly 30. The power terminals 111 are the main electrical connection parts of the terminal assembly 11, responsible for transmitting current from the connector 20 to the socket assembly 30 and the electrical equipment. Each power terminal 111 has a certain conductivity and can carry a specific current load.
[0044] The function of the limiting member 112 is to ensure the correct position and alignment of the power terminals 111. The limiting member 112 is constructed with a certain shape and size to accurately fix multiple power terminals 111 in designated positions and prevent the power terminals 111 from shifting due to vibration or pressure during use. The limiting member 112 can effectively limit the range of movement of the power terminals 111, thereby maintaining the stability and reliability of the electrical connection.
[0045] In one embodiment, the vehicle discharge gun also includes a circuit board 113 disposed on the limiting member 112, and the terminal assembly 11 also includes a signal terminal 114, one end of which is electrically connected to the circuit board 113, and the other end is located on the connector 20 for connecting to the vehicle.
[0046] For example, an integrated circuit may be disposed on the circuit board 113, wherein the integrated circuit includes an overload protection module. This overload protection module is designed to improve the safety of the electrical equipment and effectively prevent potential risks caused by current overload. Specifically, the structure of the overload protection module enables intelligent protection at room temperature. When the load current exceeds three times its rated current, the overload protector will quickly activate the protection mechanism. This protection mechanism will immediately stop the charging process, thereby preventing damage to the circuit board 113 and the electrical equipment caused by the current overload.
[0047] Within 80 seconds after the overload protector stops charging, the system will automatically perform a self-check and prepare for recovery. After an 80-second cooling and recovery period, the overload protection module will re-enable the charging function, thus restoring normal operation.
[0048] In this embodiment, not only can the circuit board 113 monitor and adjust the current input to the electrical equipment in real time, but the safety of power transmission is also greatly improved. Through an effective overload protection mechanism, equipment damage or fire risks caused by excessive current can be prevented, thereby ensuring the user's electrical safety and the long-term stable operation of the equipment.
[0049] In one embodiment, the connector 20 includes a second sub-housing 21 with multiple terminal holes for signal terminals 114 and / or power terminals 111 to pass through. The signal terminals 114 are used to transmit low-voltage, low-current signals, such as control signals, and are typically used for signal transmission and reception. The power terminals 111 are used to transmit high-voltage, high-current power, allowing current to flow and supply power to electrical equipment.
[0050] See Figure 4 , Figure 4 A side view of a discharge gun in one embodiment is shown. Exemplarily, the connector 20 can be connected to the housing 10 via bolts 22, enabling detachment from the housing 10. The connector 20 includes multiple terminal holes, each for inserting a terminal. Exemplarily, this embodiment includes multiple signal terminals 114 and multiple power terminals 111. The signal terminals 114 include PP and PE terminals, with a resistor connected between the PP and PE terminals, and are connected to the vehicle's output circuit board 113, enabling identification of the vehicle's discharge mode.
[0051] In some embodiments, signal terminals 114 and / or power terminals 111 are typically equipped with a first sealing ring 115 to ensure the reliability and safety of the electrical connection. Specifically, the first sealing ring 115 serves both an isolation function and a buffering function.
[0052] Specifically, the first sealing ring 115 effectively isolates the signal terminal 114 or power terminal 111 from other electrical components. This isolation prevents electrical short circuits or interference, protecting the signal terminal 114 and power terminal 111 from external environmental influences. For example, it prevents moisture, dust, or other contaminants from entering the terminal area, thus avoiding electrical performance degradation or equipment failure. In addition to isolation, the first sealing ring 115 also provides a cushioning effect. It reduces the impact of terminal movement during operation or vibration on the equipment. By effectively cushioning vibration and impact, the first sealing ring 115 reduces physical damage to the terminals caused by movement or collision. This not only helps extend the service life of the equipment but also ensures the stability and reliability of the equipment in various operating environments.
[0053] In addition, a sealing plug 116 can be designed to allow the power terminal 111 to pass through and be secured. The sealing plug 116 not only provides a secure fixation function but also a sealing function, thereby significantly improving the stability of the entire structure. Specifically:
[0054] The sealing plug 116 effectively secures the power terminal 111 in a predetermined position. Through its precisely designed aperture and mating structure, the sealing plug 116 ensures that the power terminal 111 will not shift or loosen during assembly. This robust securing function is crucial for ensuring the reliability of electrical connections, especially in environments with significant vibration or impact, preventing poor contact or connection breakage caused by terminal movement.
[0055] The sealing plug 116 also prevents external environmental factors such as moisture, dust, and oil from entering the internal electrical connection area. Through a tight seal formed by the sealing material, it prevents these contaminants from damaging the power terminals 111 and their connection areas, thereby improving the system's protection level. This sealing function helps extend the equipment's service life and ensures stable operation even under harsh environmental conditions.
[0056] In summary, the sealing plug 116 plays a crucial role in the design of the power terminal 111, not only enhancing the stability of the electrical connection but also providing additional protection to ensure the safety and stability of the equipment under various operating conditions.
[0057] In one embodiment, an annular groove is provided at the end of the connector 20 that connects to the housing 10, and the annular groove accommodates the second sealing ring 23. Thus, the second sealing ring 23 is disposed between the connector 20 and the housing 10. Similar to the first sealing ring 115, the second sealing ring 23 can serve both a sealing function and a buffering function.
[0058] Optionally, the socket assembly 30 and the housing 10 are snap-fit or screw-fit, and the connector 20 and the socket assembly 30 are snap-fit or screw-fit. Snap-fit connections generally facilitate quick installation and removal, while screw-fit connections provide stronger mechanical fixing force. In practical applications, these connection methods ensure a secure fit and reliable operation between components.
[0059] The socket assembly 30 and the housing 10 can be connected by either snap-fit or screw-fit, allowing the socket assembly 30 to be secured to the housing 10 during assembly and installation via either a snap-fit engagement or a threaded connection. Snap-fit typically involves inserting certain components of the socket assembly 30 into mating grooves or protrusions within the housing 10, achieving a secure connection through a physical embedding and locking mechanism. Screw-fit uses screws and nuts to firmly fix the socket assembly 30 to the housing 10, providing higher mechanical strength and stability, suitable for applications requiring a more robust connection.
[0060] Similarly, the connector 20 and the socket assembly 30 can also be connected by a snap-fit or a screw-fit method. The snap-fit method allows the connector 20 to engage with the socket assembly 30 through an embedded structure, typically used in situations requiring quick assembly and disassembly. The screw-fit method connects the connector 20 and the socket assembly 30 via threads, suitable for situations requiring secure fixing, ensuring that the connector 20 will not loosen or shift during use. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; however, as long as the combinations of these technical features do not contradict each other, they should be considered within the scope of this specification.
[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
