[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] The following detailed description of the overall structure, working principle, and technical effects of the discharge gun assembly provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0026] Please refer to Figures 1-4 The discharge gun assembly provided by this utility model is applied to electric vehicles equipped with bidirectional charging function. The discharge gun assembly functions as an energy conversion and output interface device, with one end connected to the charging socket 11 of the electric vehicle and the other end providing a standard AC power socket 11, enabling users to safely and conveniently use the energy stored in the vehicle battery in outdoor and emergency lighting scenarios.

[0027] This discharge gun assembly includes an interface body 200 and a discharge gun head 100. The interface body 200 is mounted on a vehicle. The interface body 200 has a recessed charging interface 201. A groove 202 is also provided on the interface body 200. The groove 202 is located on the outer wall of the charging interface 201. Specifically, in this embodiment, the interface body 200 is embedded in the vehicle, resulting in a smoother overall appearance. The charging interface 201 has a cylindrical structure, internally used to mate with the plug 40 to achieve charging and discharging. The groove 202 is formed on the outer wall of the cylindrical charging interface 201.

[0028] The discharge gun head 100 includes a discharge gun head body 10 and a plug 40. The plug 40 is fixed to one side of the discharge gun head body 10. The plug 40 is used to insert into the charging interface 201 for charging and discharging. A latch 30 is rotatably provided on the discharge gun head body 10. When the plug 40 is inserted into the charging interface 201, the latch 30 rotates to engage with the groove 202 to fix the interface body 200 and the discharge gun head 100, or rotates to move out of the groove 202 to unlock the interface body 200 and the discharge gun head 100. Through the above-mentioned cooperation structure between the latch 30 and the groove 202, mechanical interlocking can be achieved while the plug 40 is electrically connected, thereby effectively preventing the discharge gun head 100 from accidentally falling off under vehicle vibration or external force, significantly improving the safety and connection reliability of the charging and discharging process.

[0029] Furthermore, a locking mechanism 20 is also provided on the discharge gun head body 10. The locking mechanism 20 includes a locking block 21 and a locking groove 22. The locking block 21 is slidably disposed on the hook 30. The locking groove 22 is disposed on the discharge gun head body 10. The locking block 21 slides into the locking groove 22 to lock the relative position of the hook 30 and the discharge gun head body 10, and the locking block 21 slides out of the locking groove 22 to unlock the relative position of the hook 30 and the discharge gun head body 10. When the hook 30 is engaged in the groove 202, the locking block 21 slides into the locking groove 22 to lock the position of the hook 30. By setting an independent locking mechanism 20, a secondary locking function can be provided after the hook 30 and the groove 202 are initially locked. This effectively prevents the hook 30 from rebounding and unlocking due to accidental force in complex usage environments (such as vibration, contact, or outdoor wind and rain), greatly improving the reliability and safety of the connection and eliminating the risk of accidental detachment while energized.

[0030] Please refer to Figure 5 Specifically, the hook 30 includes a rod 31 and a hook 32 connected in sequence. The middle position of the rod 31 is rotatably connected to the discharge gun head body 10. A cavity 14 is provided on the discharge gun head body 10 so that when the rod 31 rotates relative to the discharge gun head body 10, the hook 32 can be lifted relative to the discharge gun head body 10, and the end of the rod 31 away from the hook 32 can enter the cavity 14. A first elastic member 312 is provided in the cavity 14. The two ends of the first elastic member 312 abut against the bottom wall of the cavity 14 and the end of the rod 31 away from the hook 32, respectively. It can be understood that in this embodiment, the hook 30 forms an "L"-shaped hook 30 through the structure of the rod 31 and the hook 32 connected in sequence. During the rotation of the rod 31 relative to the discharge gun head body 10, the hook 32 can be raised or lowered relative to the discharge gun head body 10, thereby allowing the hook 32 to move out of or into the groove 202 when the plug 40 is inserted into the charging interface 201, achieving initial locking between the discharge gun head 100 and the interface body 200. By providing the first elastic element 312, the end of the rod 31 away from the hook 32 tends to move out of the cavity 14, thereby causing the hook 32 to tend to move towards the groove 202.

[0031] In this embodiment, the rod portion 31 of the hook 30 is disposed at the end of the discharge gun head body 10 near the plug 40, such that the hook portion 32 extends from the discharge gun head body 10 onto the side of the plug 40. When the rod portion 31 rotates relative to the discharge gun head body 10, the hook portion 32 can move closer to or further away from the plug 40. In this embodiment, the outer diameter of the discharge gun head body 10 is larger than the outer diameter of the plug 40. As the plug 40 is gradually inserted into the charging interface 201, the hook portion 32 abuts against the side wall of the charging interface 201, thereby causing the hook portion 32 to lift relative to the plug 40, and the rod portion 31 to rotate relative to the discharge gun head body 10. The end of the rod portion 31 away from the hook portion 32 enters the cavity 14, compressing the first elastic member 312. When the plug 40 is inserted into the charging interface 201, the hook 32 corresponds to the position of the groove 202. Under the action of the first elastic member 312, the hook 32 always moves toward the plug 40, that is, toward the groove 202, so as to enter the groove 202 and realize the hook 30 and the groove 202 to lock together and complete the initial locking of the discharge gun head 100 and the interface body 200.

[0032] Specifically, in this embodiment, a sliding groove 311 is provided at the end of the rod 31 away from the hook 32. The extending direction of the sliding groove 311 is the same as the extending direction of the rod 31. Along the extending direction of the sliding groove 311, a first opening communicating with the sliding groove 311 is provided on the rod 31. A locking block 21 is disposed in the sliding groove 311. A second elastic member 314 is disposed in the sliding groove 311, and both ends of the second elastic member 314 abut against the inner walls of the locking block 21 and the sliding groove 311, respectively, so that the locking block 21 has a tendency to pop out of the sliding groove 311 from the first opening under the action of the second elastic member 314. A locking groove 22 is formed on the side wall of the cavity 14 away from the hook 30. The part of the locking block 21 that pops out of the sliding groove 311 can enter the locking groove 22 to lock the position of the hook 30. By setting up a catapult-type locking mechanism 20 consisting of a locking groove 22, a locking block 21, a sliding groove 311, and a second elastic element 314, when the hook 30 rotates to the locking position of the groove 202, the elastic force of the second elastic element 314 can be used to pop out the locking block 21 and embed it into the locking groove 22, thereby achieving mechanical locking of the hook 30 position, effectively preventing it from accidentally rebounding and unlocking due to vibration or accidental contact, and greatly improving the reliability and security of the connection.

[0033] Specifically, the locking block 21 is disposed within the sliding groove 311 and, under the action of the second elastic element 314, always tends to slide out of the sliding groove 311. As the plug 40 is gradually inserted into the charging interface 201, the operator slides the locking block 21, retracting it into the sliding groove 311, and presses the end of the rod 31 away from the hook 32, thereby causing the hook 32 to lift relative to the plug 40, and the end of the rod 31 away from the hook 32 to rotate into the cavity 14. As the plug 40 is inserted into the charging interface 201, the operator releases the plug. The end of the rod 31 away from the hook 32 is lifted by the first elastic element 312, and the hook 32 enters the groove 202. At this time, the first opening of the sliding groove 311 is set towards the locking groove 22. The locking block 21 enters the locking groove 22 on the side wall of the cavity 14 by the action of the second elastic element 314. Through the cooperation of the locking block 21 and the locking groove 22, the rod 31 and the discharge gun head body 10 are locked, preventing the rod 31 from rotating relative to the discharge gun head body 10. This fixes the position of the hook 32 and the groove 202, locking the hook 32 in the groove 202, and completing the secondary locking of the discharge gun head 100 and the interface body 200.

[0034] Furthermore, a guide slope is provided on the side of the hook 32 away from the rod 31. As the plug 40 is gradually inserted into the charging interface 201, the guide slope of the hook 32 first abuts against the side wall of the charging interface 201. By providing the guide slope, the hook 32 is prevented from getting stuck with the charging interface 201, thus improving the smoothness of operation.

[0035] Furthermore, a limiting groove 313 is provided at the end of the rod 31 away from the hook 32. The limiting groove 313 is provided on one side of the sliding groove 311 along a direction perpendicular to the extension direction of the sliding groove 311. The extension direction of the limiting groove 313 is the same as the extension direction of the sliding groove 311. A limiting block 23 is also fixedly provided on one side of the locking block 21. The limiting block 23 is slidably disposed within the limiting groove 313. Along the extension directions of the limiting groove 313 and the sliding groove 311, the length of the limiting groove 313 is less than the length of the sliding groove 311. Specifically, the locking block 21 and the limiting block 23 move synchronously, and the locking block 21 stops moving when the limiting block 23 abuts against the side wall of the limiting groove 313. It can be understood that by providing the limiting groove 313 and the limiting block 23, the sliding distance of the locking block 21 within the sliding groove 311 can be limited, thereby preventing the locking block 21 from sliding out of the first opening of the sliding groove 311.

[0036] To facilitate manual unlocking of the locking mechanism 20, in this embodiment, the rod 31 is also provided with a second opening communicating with the limiting groove 313. The second opening is located on one side of the limiting groove 313 along the extension direction perpendicular to the limiting groove 313. An auxiliary disassembly block 24 is also fixedly connected to the side of the limiting block 23 away from the locking block 21. The auxiliary disassembly block 24 extends out of the limiting groove 313 from the second opening, and the size of the auxiliary disassembly block 24 is larger than the size of the limiting groove 313. It can be understood that when the discharge gun head 100 and the interface body 200 are in the locked state, the locking block 21 is located within the locking groove 22, and the hook 30 is fixed relative to the discharge gun head body 10. When it is necessary to remove the discharge gun head 100 from the interface body 200, the auxiliary disassembly block 24 can be manually slid to move the limiting block 23 and the locking block 21, so that the locking block 21 disengages from the locking groove 22. At this time, the auxiliary disassembly block 24 can be pressed to lift the hook 32 at the other end of the hook 30, and the hook 32 disengages from the groove 202. The discharge gun head 100 can then be manually pulled out to separate the discharge gun head 100 from the interface body 200.

[0037] By setting the size of the auxiliary disassembly block 24 to be larger than the size of the limiting groove 313, it can be ensured that the auxiliary disassembly block 24 is always exposed within the operator's visible and accessible range, which greatly facilitates manual force application and allows for quick and effortless unlocking operations, effectively improving the convenience of the disassembly process and the user experience.

[0038] Furthermore, the discharge gun head body 10 is provided with a mounting groove 15. The rod 31 is embedded in the mounting groove 15. The depth of the mounting groove 15 is the same as the thickness of the rod 31. It can be understood that by providing the mounting groove 15, the outer surface of the discharge gun head body 10 remains smooth after the rod 31 is embedded in the mounting groove 15, without any protrusions or depressions. This not only improves the aesthetics of the product but also prevents external foreign objects from snagging or bumping the rod 31, thereby improving the safety and reliability of use.

[0039] In this embodiment, the auxiliary unlocking block 24 is provided with anti-slip protrusions. By providing anti-slip protrusions, the friction between the user's finger and the auxiliary unlocking block 24 can be increased, thereby making the user more stable and effortless when sliding the auxiliary unlocking block 24 to perform the unlocking operation, preventing slippage, and further improving the convenience and reliability of the unlocking operation.

[0040] Please refer to Figure 4Furthermore, this embodiment also includes a triple-locking structure, with a retractable locking rod 203 on the interface body 200. When the hook 30 is engaged with the groove 202, the locking rod 203 extends out of the interface body 200 and abuts against the side of the hook 30 away from the groove 202. By providing this retractable locking rod 203, a locking structure controlled by the vehicle end can be provided in addition to the hook 30 and the locking mechanism 20, thereby completely eliminating the possibility of the hook 30 accidentally springing back and unlocking due to abnormally strong pressure, providing the highest level of safety guarantee for the entire discharge connection process.

[0041] Please refer to Figures 1-3 The discharge gun head body 10 has arc-shaped grooves 13 on two opposite sides. Anti-slip ribs 131 are spaced apart on the arc-shaped grooves 13. By setting arc-shaped grooves 13 that fit the shape of the hand and anti-slip ribs 131 that increase friction, the comfort and stability of the operator when holding the gun can be significantly improved. This can effectively prevent operational errors caused by hand slippage during insertion, removal or holding, and further improve the convenience and safety of use.

[0042] Furthermore, a socket 11 and a dust cover 12 are provided at the end of the discharge gun head body 10 away from the plug 40. The dust cover 12 is rotatably connected to the discharge gun head body 10 to cover or expose the socket 11. It is understood that the socket 11 provides a standard AC power interface for users, allowing for convenient and safe connection of external electrical equipment. By providing an openable dust cover 12, the socket 11 can be completely covered when not in use, effectively preventing dust, liquids, or other foreign objects from entering the socket 11, avoiding the risk of poor contact or short circuits, extending the service life of the socket 11, and ensuring electrical safety.

[0043] This embodiment also provides an electric vehicle that includes the discharge gun assembly described in the above embodiments. By equipping the electric vehicle with this discharge gun assembly that integrates mechanical locking and multiple safety protections, the electric vehicle can have a safe and convenient external discharge capability, thereby meeting the user's needs for reliable power in various scenarios such as outdoor camping, emergency power supply, and others, significantly improving the vehicle's functionality and practical value.

[0044] The beneficial effects of the discharge gun assembly and electric vehicle provided by this utility model include: The discharge gun assembly provided by this utility model includes an interface body 200 and a discharge gun head 100. The interface body 200 is mounted on a vehicle. A recessed charging interface 201 is provided on the interface body 200. A groove 202 is also provided on the interface body 200. The groove 202 is located on the outer side wall of the charging interface 201. The discharge gun head 100 includes a discharge gun head body 10 and a plug 40. The plug 40 is fixed to the discharge gun head body 10 and has a hook 30. When the plug 40 is inserted into the charging interface 201, the hook 30 engages with the groove 202 to secure the interface body 200 and the discharge gun head 100. A locking mechanism 20 is also provided on the discharge gun head body 10. When the hook 30 engages with the groove 202, the locking mechanism 20 can selectively lock the position of the hook 30. By designing a structure where the hook 30 engages with the groove 202, an interlocking mechanism can be established between the discharge gun head 100 and the interface body 200 after the plug 40 is inserted into the charging interface 201, preventing the discharge gun head 100 from accidentally detaching due to external pulling or vehicle vibration. By adding a locking mechanism 20 to the discharge gun head body 10, the position of the hook 30 is locked in the groove 202 when it is engaged, preventing it from detaching from the groove 202 under external force, thus achieving double protection. This invention ensures the firmness and safety of the connection when the plug 40 is inserted into the charging interface 201, preventing accidental detachment.

[0045] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
