At the same time, the charging port cover is sunk into the rear of the counterweight block to prevent accidental collisions.

[0006] A charging port cover structure for an electric loader comprises a charging support and a charging port cover. The charging support and the charging port cover are welded and fixed to the rear of a counterweight block of the loader.

[0007] Furthermore, a water leakage groove is provided inside the charging support, and a sealing ring is provided on the charging support.

[0008] Furthermore, a locking structure is provided between the charging port cover and the charging support.

[0009] Furthermore, the charging port cover is also provided with a positioning pin and a limit switch.

[0010] Furthermore, the limit switch is a connecting rod structure, one end of the connecting rod structure is connected to the charging port cover, and the other end is connected to the charging support. When the charging port cover is closed in place, the positioning pin is triggered to ensure a stable locking state between the charging port cover and the charging support.

[0011] Furthermore, the steel plate material used for the charging port cover and the charging support is 355B.

[0012] Furthermore, the charging port cover is opened in a flip-up manner.

[0013] Furthermore, the flip-up opening is achieved by a hinge, and the charging port cover and the charging support are fixedly connected by the hinge.

[0014] Furthermore, the opening angle of the charging port cover is at least 90 degrees.

[0015] Furthermore, a fast charging interface is provided on the inner side of the charging port cover, and the fast charging interface includes at least two for contacting the plug of the charging device.

[0016] Compared with the prior art, the electric loader charging port cover structure provided by the present invention has the following beneficial effects:

[0017] ① The utility model improves the operational convenience of the electric loader charging operation. Since the charging port cover is arranged at the rear of the counterweight block, the operator can easily perform the charging operation without bending over.

[0018] ② The charging port cover design provided by the utility model enhances the protection of the charging port. The design of the charging port cover sunk into the rear of the counterweight effectively avoids possible damage from bumps and collisions in harsh working environments.

[0019] ③ The charging port cover provided by this utility model has a compact and reasonable overall design. The provision of a drainage groove and a sealing ring improves the cover's waterproof performance. The locking structure ensures that the cover remains locked when not charging. The design of the positioning pin and limit switch makes opening and closing the cover more accurate and convenient. The flip-up opening method makes opening and closing the cover simpler and faster.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figures 1 to 2 , the pink line shows an electric loader charging port cover structure provided by the utility model, which includes a charging support (5) and a charging port cover (2). The charging support (5) and the charging port cover (2) are fixed to the rear of the loader's counterweight (1) by welding, ensuring the stability and reliability of the structure.

[0026] A water leakage groove is specially designed inside the charging support (5) to cope with the problem of water leakage that may occur when used in harsh environments, thereby protecting the safety of the internal circuit.

[0027] At the same time, the charging support (5) is equipped with a sealing ring, which further enhances its waterproof performance and ensures the sealing of the charging port.

[0028] In order to ensure the safety and reliability of the charging port cover, a locking structure is designed between the charging port cover (2) and the charging support (5). The locking structure ensures that the charging port cover remains locked when not charging.

[0029] In addition, the charging port cover (2) is also equipped with a positioning pin and a limit switch. The limit switch is a connecting rod structure. One end of the connecting rod structure is connected to the charging port cover, and the other end is connected to the charging support. When the charging port cover is closed in place, the positioning pin is triggered to ensure that a stable locking state is formed between the charging port cover and the charging support.

[0030] The steel plate material selected for the charging port cover (2) and the charging support (5) is 355B. The selected 355B steel plate material has good strength and corrosion resistance, ensuring the durability and reliability of the charging port cover.

[0031] The charging port cover (2) is opened in a flip-up manner. The flip-up opening manner is easy to operate and is convenient for maintenance personnel to perform charging operations and daily inspections.

[0032] The flip-up opening mode is achieved by a hinge (3), and the charging port cover (2) and the charging support (5) are fixedly connected by the hinge (3).

[0033] The opening angle of the charging port cover (2) is at least 90 degrees.

[0034] The inner side of the charging port cover (2) is provided with a fast charging interface (4), and there are at least two fast charging interfaces (4) for contacting the plug of the charging device.

[0035] The working principle of this utility model is:

[0036] When charging the electric loader, the operator can easily flip the charging port cover open using a hinge, revealing the quick-charge port inside. Once the quick-charge port connects to the charging device's plug, charging begins. Because the charging port cover opens at a minimum of 90 degrees, it provides ample space for the charging device to connect, ensuring a smooth charging process.

[0037] In the description of this specification, the terms "connect", "install", "fix", "set", etc. are understood in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. As in this example, for ordinary technicians in this field, the specific meanings of the above terms in this utility model or utility model can be understood according to specific circumstances.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
