Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, and in particular to a discharge gun locking structure. Background Technology

[0002] Electric vehicles equipped with bidirectional on-board chargers convert battery power into 220V AC power for user use via an inverter when not charging. In this case, the charging dock also functions as a discharging dock. When the discharge gun connects to the vehicle's interface and discharges, a mechanical interlock between the hook and the interface is required to maintain stability and monitorability, ensuring product functionality. Therefore, a hook is installed on the discharge gun to connect to the charging dock. However, current market solutions for connecting the discharge gun and dock have several shortcomings. Most existing locking structures use simple snap-fit ​​or plug-in designs, which are prone to accidental detachment of the discharge gun from the dock due to external force after connection. For example, during vehicle discharge, slight vehicle movement, unintentional collisions with the charging cable, or pressure from surrounding objects can cause the discharge gun to fall off the dock, interrupting the discharge process, affecting efficiency, and potentially generating sparks, leading to fires and other serious safety accidents. Furthermore, some locking structures lack effective protection mechanisms. In complex environments such as humid or dusty conditions, external impurities can easily enter the locking area, leading to loose connections or component damage, failing to meet the ever-increasing demands for safe use. Therefore, a new solution is urgently needed in the existing technology to address these issues. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] A discharge gun locking structure is provided for connection to a discharge base 1, wherein the discharge base 1 has a locking slot 11, such as... Figures 1-5 As shown, it includes: discharge gun body 2, locking rod 3, pressing part 4, protective part 5, and support part 6;

[0036] One end of the locking rod 3 is a pressing end 31, and the other end has a locking hook 32;

[0037] A hinge part 33 is provided between the pressing end 31 and the locking hook 32, and the hinge part 33 is hinged to the discharge gun body 2.

[0038] The support member 6 is disposed on the discharge gun body 2;

[0039] The protective component 5 is mounted on the support component 6 and is movable along the extension direction of the discharge gun body 2.

[0040] The pressing end 31 is supported on the discharge gun body 2 by a spring 41;

[0041] When the discharge gun body 2 and the discharge base 1 are connected, the locking hook 32 extends into the locking port 11, and the protective part 5 moves to the locking position to prevent the pressing end 31 from being pressed by external force.

[0042] The discharge gun body 2 is made of high-strength insulating material, possessing excellent insulation performance and mechanical strength. The locking rod 3 is made of metal, and its hinge part 33 is hinged to the discharge gun body 2 via a pin, ensuring that the locking rod can rotate flexibly. The support member 6 is mounted on the discharge gun body 2, and the protective member 5 is mounted on the support member 6 via a sliding connection. The spring 41 is a compression spring with a suitable elastic coefficient, one end of which is fixed to the discharge gun body 2, and the other end supports the cover 43 of the pressing member 4. When the discharge gun body 2 is inserted into the discharge base 1, the locking hook 32 smoothly extends into the locking port 11, and then pushes the protective member 5 to move along the extension direction of the discharge gun body 2 to the locked position. In the locked position, the protective member 5 cooperates with the pressing member 4, effectively preventing the pressing end 31 from being pressed by external force, thus achieving a stable connection between the discharge gun body 2 and the discharge base 1.

[0043] In some embodiments, when the protective member 5 is disengaged from the locking position, pressing the pressing end 31 causes the locking hook 32 to lift away from the locking opening 11, allowing the discharge gun body 2 to detach from the discharge base 1. When it is necessary to separate the discharge gun body 2 from the discharge base 1, the protective member 5 is moved away from the locking position. At this time, pressing the pressing end 31 causes the locking rod 3 to rotate around the hinge 33 under the action of the spring 41, lifting the locking hook 32 away from the locking opening 11, thereby easily separating the discharge gun body 2 from the discharge base 1. The operation is simple and convenient, and the safety of the separation process is ensured.

[0044] In some embodiments, such as Figure 3 As shown, the pressing member 4 includes a column 42 and a cover 43 connected to each other. The spring 41 is sleeved on the column 42 and supports the cover 43 at one end, while the other end is connected to the discharge gun body 2.

[0045] The column 42 and cover 43 of the pressing component 4 are made of one piece, which improves the strength and stability of the structure. The spring 41 is tightly fitted on the column 42, and the inner diameter of the spring 41 is matched with the outer diameter of the column 42, ensuring that the spring 41 will not shift during compression and extension. The diameter of the cover 43 is larger than the diameter of the column 42, which facilitates its cooperation with the spring 41 and the protective component (5) to achieve effective support and protection for the pressing end 31.

[0046] In some embodiments, such as Figure 4As shown, the protective member 5 has a groove 51. The protective member 5 is located in the locked position, and the groove 51 at least partially fits onto the column 42. The protective member 5 prevents the cover 43 from moving downward. The groove 51 of the protective member 5 adopts a U-shaped design, and its size matches the column 42 and the cover 43 of the pressing member 4. When the protective member 5 is in the locked position, the groove 51 at least partially fits onto the column 42 and can prevent the cover (43) from moving downward, thereby effectively preventing the pressing end 31 from being pressed by external force, and further improving the anti-misoperation performance of the locking structure.

[0047] In some embodiments, such as Figure 4 As shown, the support member 6 has a slide 61, and the protective member 5 includes a pushing part 52, a connecting part 53 and a locking part 54 connected from top to bottom. The pushing part 52 is located above the support member 6, the locking part 54 is located below the support member 6, the connecting part 53 is movable in the slide 61 along the length direction of the discharge gun body 2, and the groove 51 is provided on the locking part 54.

[0048] The slide 61 of the support member 6 is a rectangular groove, the width and depth of which are adapted to the connecting part 53 of the protective member 5, ensuring that the connecting part 53 can move smoothly along the length of the discharge gun body 2 in the slide 61. The pushing part 52 of the protective member 5 is designed as a circular protrusion, making it easy for the operator to push the protective member 5 by hand. The groove 51 on the locking part 54 cooperates with the pressing part 4 to realize the locking and unlocking functions.

[0049] In some embodiments, the support member 6 has an opening 62 communicating with the slide rail 61, the opening 62 for placing the connecting part 53 into the slide rail 61. The opening 62 of the support member 6 is a rectangular opening, the size of which is slightly larger than the size of the connecting part 53 of the protective member 5, facilitating the entry of the connecting part 53 into the slide rail 61 through the opening 62. When installing the protective member 5, the connecting part 53 is first aligned with the opening 62, then pushed into the slide rail 61, and then other components are installed, simplifying the installation process and improving production efficiency.

[0050] In some embodiments, such as Figure 4 As shown, the support member 6 has a through hole 63 for the column 42 to pass through. The through hole 63 of the support member 6 is a circular hole, the diameter of which matches the diameter of the column 42 of the pressing member 4, ensuring that the column 42 can pass smoothly through the through hole 63 and remain stable during movement. The through hole 63 allows the pressing member 4 to better cooperate with the protective member 5 to achieve locking and unlocking functions.

[0051] In some embodiments, such as Figure 3As shown, the locking part 54 is provided with a reinforcing rib 55. The reinforcing rib 55 further enhances the structural strength of the locking part 54. The height and width of the reinforcing rib 55 are designed according to the actual stress conditions of the protective part 5, ensuring that stress can be effectively distributed when subjected to external forces, preventing damage to the protective part 5, and extending the service life of the locking structure.

[0052] In some embodiments, such as Figure 5 As shown, the device also includes a mounting base 7, a support member 6, and at least a portion of a protective member 5 disposed within the cavity of the mounting base 7. The support member 6 is engaged with the bottom of the mounting base 7 via a foot 64. Part of the structure of the protective member 5 is located within the cavity of the mounting base 7. Under the protection of the mounting base 7, it can effectively prevent external factors from interfering with the protective member 5, ensuring the normal operation of the locking structure.

[0053] In some embodiments, the discharge gun body 2 has a receiving cavity 21, and the mounting base 7 is at least partially disposed within the receiving cavity.

[0054] The receiving cavity 21 of the discharge gun body 2 is designed according to the dimensions of the mounting base 7, ensuring that the mounting base 7 can be securely placed at least partially within the receiving cavity 21. This design makes the entire locking structure more compact, saves space, and improves the overall aesthetics and practicality of the discharge gun body 2.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
