Description

Technical Field

[0001] The utility model belongs to the technical field of electrical boxes and relates to an electrical box. Background Art

[0002] With the continuous improvement of people's living standards, people's outdoor travel and leisure activities are increasing. When using electricity outdoors, some high-power electrical devices are usually configured, such as water heaters and induction cookers. For these electrical devices to be used normally in the wild environment, the energy storage batteries configured in the vehicle or on the boat need to be used as vehicle-mounted power sources. Specifically, when designing the power supply, there is usually no suitable outer casing for selection, and it is necessary for personnel to manually open holes in the outer casing to install accessories, which is not convenient for operation.

[0003] In view of the above problems, the existing technology discloses a multifunctional power box as disclosed in Chinese Patent Application [Authorization Publication No.: CN221177334U], which includes a bottom case and a top case. The top of the bottom case is open, and the top opening is combined and installed with a top case for closing. The inner bottom surface of the top case is provided with an inverter module. Several AC sockets electrically connected to the inverter module are integrally arranged on one side of the top case for providing AC power output through the AC sockets. Several Anderson interfaces are integrally arranged on the other side of the top case for providing DC power output through the Anderson interfaces. A solar charge controller module is installed on the inner bottom surface of the top case beside the inverter module.

[0004] Although the above structure realizes the setting of multiple AC sockets on the top case through the setting of the bottom case and the top case, since the top case and the bottom case are usually made of plastic material to ensure safety, the strength of the top case and the bottom case is low, reducing the stability of the power box during use. Summary of the Utility Model

[0005] The purpose of the present utility model is to propose an electrical box in view of the above problems existing in the prior art. The technical problem to be solved by the present utility model is: how to solve the problem that the strength of the top case and the bottom case of the existing electrical box is low.

[0006] The purpose of the present utility model can be achieved by the following technical solutions:

[0007] An electrical box includes a lower bottom case with an upward opening and an upper cover with a downward opening. It is characterized in that the electrical box further includes a metal plate disposed between the lower bottom case and the upper cover. The metal plate is fixedly connected to the lower bottom case and blocks the opening of the lower bottom case. The upper cover is disposed on the metal plate and fixedly connected to the metal plate, and the metal plate blocks the opening of the upper cover. One end of the metal plate is located outside the upper cover, and a plurality of plug connectors are provided on this end.

[0008] Working principle: A metal plate is provided between the lower bottom case and the upper cover. The upper end of the metal plate can block the opening of the upper cover, and the lower end can block the opening of the lower bottom case, increasing the connection stability between the lower bottom case and the upper cover and enhancing the strength of the entire connection after assembly. This makes the lower bottom case and the upper cover stronger. One end of the metal plate is located outside the upper cover, and multiple plug connectors are provided at this end, facilitating the plugging and use of electrical appliances, improving the integration of the electrical appliance box, and rationally utilizing the space at the front end of the upper cover. After separating the lower bottom case and the upper cover through the metal plate, the spaces of the lower bottom case and the upper cover do not affect each other, making it more convenient to arrange circuit boards and other components inside the lower bottom case and the upper cover, resulting in a higher integration and space utilization rate of the entire electrical appliance box.

[0009] In the above electrical appliance box, an annular abutting portion is provided below the metal plate, and an annular mounting step is formed on the upper end of the lower bottom case. The abutting portion is arranged on the mounting step and fixedly connected by fasteners.

[0010] Through the cooperation of the abutting portion and the mounting step, the metal plate can be entirely located inside the lower bottom case, and positioning is achieved by arranging the abutting portion on the mounting step. Then, through fixed connection with fasteners, the connection between the metal plate and the lower bottom case is convenient.

[0011] In the above electrical appliance box, an annular mounting gasket one is provided on the mounting step, and the abutting portion presses the mounting gasket one against the mounting step.

[0012] Through the setting of the mounting gasket one, the connection between the abutting portion and the mounting step becomes more stable.

[0013] In the above electrical appliance box, a supporting portion protrudes upward above the metal plate, and an annular limiting ring groove is formed on the lower end of the upper cover. The supporting portion is embedded in the limiting ring groove and fixedly connected by fasteners.

[0014] Through the setting of the supporting portion, while ensuring the overall thickness and strength of the metal plate, it can also achieve the rapid installation of the metal plate and the upper cover through cooperation with the limiting ring groove.

[0015] In the above electrical appliance box, an annular mounting gasket two is provided on the supporting portion, and the upper cover presses the mounting gasket two against the supporting portion.

[0016] The setting of the mounting gasket two improves the connection stability between the supporting portion and the upper cover.

[0017] In the above electrical appliance box, a plurality of electrical plugging holes are provided on the upper cover.

[0018] The setting of the electrical plugging holes enables other electrical appliance sockets to be inserted into the upper cover for power supply, resulting in a better power supply effect for the electrical appliance box.

[0019] Compared with the prior art, the electrical box has the following advantages: The metal plate strengthens the strength of the entire electrical box. One end of the metal plate is located outside the upper cover, and multiple plug connectors are provided at this end, facilitating the plugging and use of electrical appliances, improving the integration of the electrical box, and also reasonably utilizing the space at the front end of the upper cover. After separating the lower bottom shell from the upper cover through the metal plate member, the spaces of the lower bottom shell and the upper cover do not affect each other, and the layout of circuit boards and other parts in the lower bottom shell and the upper cover is more convenient, making the entire electrical box have higher integration and higher space utilization rate.
