[0026] 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.

[0027] Example

[0028] Please see Figures 1-5 The present invention provides the following technical solution:

[0029] A maintenance-friendly bidirectional charger includes:

[0030] Bidirectional charging body 1;

[0031] Charger top cover 2 is rotatably connected to the upper end of bidirectional charger body 1 via a rotating shaft;

[0032] The quick-load assembly consists of two sets. Each set includes a lower insertion fixing cylinder 3, an upper rotating connecting plate 4, an insertion groove 5, a spring groove 6, a spring push plate 7, a fixed insertion block 8, a fixed spring 9, a fixed insert plate 10, and a fixed insertion hole 11. The lower insertion fixing cylinder 3 is fixedly connected to one side of the charger's upper cover plate 2. The upper rotating connecting plate 4 is fixedly connected to one side of the bidirectional charger body 1. The insertion groove 5 is located on one side of the lower insertion fixing cylinder 3. The spring groove 6 is located on one side of the inner wall of the insertion groove 5. The spring push plate 7 is slidably connected to the spring groove 6. The fixed spring 9 is fixedly connected to one side of the spring push plate 7 and one side of the inner wall of the spring groove 6. The fixed insert plate 10 is located at the lower end of the upper rotating connecting plate 4 and slides within the insertion groove 5. The fixed insertion hole 11 is located on one side of the fixed insert plate 10. The fixed insertion block 8 is fixedly connected to one side of the spring push plate 7 and slides within the fixed insertion hole 11.

[0033] In a specific embodiment of this utility model, the insertion slot 5 is used to accommodate the fixed insert plate 10. When the charger cover plate 2 rotates and the bidirectional charger body 1 closes, the fixed insert plate 10 slides into the insertion slot 5. The fixed insert block 8 can be inserted into the fixed insert hole 11 and matched with it to achieve locking. The fixed spring 9 connects the spring push plate 7 and the inner wall of the spring groove 6, and provides elastic thrust when the charger cover plate 2 is closed. When the device is closed, the charger cover plate 2 is rotated to make the fixed insert plate 10 insert into the insertion slot 5. The fixed insert plate 10 contacts the fixed insert block 8 and squeezes the spring push plate 7 to slide into the spring groove 6. At this time, the fixed spring 9 is squeezed and contracted. When the fixed insert plate 10 is fully inserted into the insertion slot 5, the previously squeezed and contracted fixed spring 9 rebounds and pushes the fixed insert block 8 into the fixed insert hole 11 to complete the connection. The charger cover plate 2 closes quickly. The quick installation and closing allows for quick disassembly and assembly of the cover plate without tools, shortening maintenance time and reducing thread wear during disassembly, thus extending the equipment life.

[0034] Please refer to the details. Figures 1-5 An inclined surface 18 is provided on one side of the fixed insertion block 8. The inclined surface 18 is the contact surface between the fixed insertion plate 10 and the fixed insertion plate 10 when the fixed insertion plate 10 is inserted into the insertion slot 5.

[0035] In this embodiment, the inclined surface 18 is opened on one side of the fixed insertion block 8, which is the contact surface between the fixed insertion plate 10 and the fixed insertion plate 10 when the fixed insertion plate 10 is inserted into the insertion slot 5, so as to guide the fixed insertion plate 10 to slide in smoothly and compress the fixed spring 9.

[0036] Please refer to the details. Figures 1-5 A disassembly slide groove 14 is provided on one side of the inner wall of the insertion slot 5. A disassembly push rod 13 is fixedly connected to one side of the fixed insertion block 8. The disassembly push rod 13 is slidably connected in the disassembly slide groove 14.

[0037] In this embodiment: During maintenance, press the disassembly lever 13, and the fixed insertion block 8 will be disengaged from the fixed insertion hole 11 by the guiding action of the disassembly slide 14. Then the charger cover plate 2 can be flipped over, and the lock can be quickly released by disassembling the lever 13 without tools.

[0038] Please refer to the details. Figures 1-5 A connecting groove 12 is provided on one side of the fixed insertion hole 11. The connecting groove 12 avoids contact with the disassembly lever 13 when the fixed insert plate 10 is inserted into the insertion groove 5.

[0039] In this embodiment: a connecting groove 12 is provided on the side of the fixed insertion hole 11 to ensure that the fixed insert plate 10 maintains a safe distance from the disassembly push rod 13 when it is inserted, thereby eliminating motion interference between components and ensuring smooth operation.

[0040] Please refer to the details. Figures 1-5 The upper end of the lower insertion fixed cylinder 3 is provided with a reset groove 15. The upper cover plate ejection block 16 is slidably connected in the reset groove 15. The lower end of the upper cover plate ejection block 16 is fixedly connected to the lower inner wall of the reset groove 15 with an ejection spring 17. The upper end of the upper cover plate ejection block 16 is in contact with the upper rotating connecting plate 4.

[0041] In this embodiment: when locked, the pop-out spring 17 is compressed and the upper cover pop-out block 16 maintains contact pressure with the upper rotating connecting plate 4. When the release lever 13 is pressed to unlock, the pop-out spring 17 releases its elastic force and the upper cover pop-out block 16 pushes the upper rotating connecting plate 4 upward. The charger upper cover 2 automatically pops open at a certain angle. After unlocking, it automatically pops open, reducing operation steps. When the charger upper cover 2 is pressed down, the upper cover pop-out block 16 is pressed down and the pop-out spring 17 recharges.

[0042] Please refer to the details. Figures 1-4 Electrical connection holes 19 are provided at both the front and rear ends of the bidirectional charging body 1.

[0043] In this embodiment, four electrical connection holes 19 are provided at the front and rear, including a power interface, a communication interface, and a grounding interface. The design is designed to prevent mis-insertion, supports bidirectional access at both the front and rear, allows multiple devices to be connected in parallel, and has an automatic identification function.

[0044] The working principle and usage process of this utility model are as follows: The insertion slot 5 is used to accommodate the fixed insertion plate 10. When the charger cover 2 rotates and the bidirectional charger body 1 closes, the fixed insertion plate 10 slides into the insertion slot 5. The fixed insertion block 8 can be inserted into the fixed insertion hole 11 and matched with it to achieve locking. The fixed spring 9 connects the spring push plate 7 and the inner wall of the spring groove 6, and provides elastic thrust when the charger cover 2 is closed. When the device is closed, the charger cover 2 is rotated to make the fixed insertion plate 10 insert into the insertion slot 5. The fixed insertion plate 10 contacts the fixed insertion block 8 and squeezes the spring push plate 7 to slide into the spring groove 6. At this time, the fixed spring 9 is squeezed and contracted. When the fixed insertion plate 10 is fully inserted into the insertion slot 5, the previously squeezed and contracted fixed spring 9 rebounds and pushes the fixed insertion block 8 into the fixed insertion hole 11 to complete the connection. The charger cover 2 closes quickly. The quick installation and closing allows for quick disassembly and assembly of the cover without tools, shortening maintenance time and reducing thread wear during disassembly, thus extending the equipment life.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
