[0002] Existing electric chain hoists include a motor assembly, a reducer assembly, a transmission assembly, and a chain assembly. The motor assembly includes a motor connected to an input shaft. The chain assembly includes a lifting chain, one end of which is housed in a chain storage box, and the other end is connected to a hook assembly. The transmission and reducer assemblies serve a safety function, preventing the hook assembly in the chain assembly from breaking or loosening during cargo handling, thus avoiding potential hazards. All components of the electric hoist, including the motor assembly, reducer assembly, transmission assembly, and chain assembly, are housed within a single enclosure. Some electric chain hoists also have an external control panel for controlling the electrical equipment within the hoist.

[0003] The existing technical solutions mentioned above have the following drawbacks: all components of the electric chain hoist are installed in the casing, there are many parts, and they are not easy to observe, which makes it very inconvenient for operators to maintain the electric hoist.

[0004] Later, electric chain hoists that were easier to maintain emerged. Although the three-phase single-chain electric chain hoist with authorization announcement number CN211496704U, with authorization announcement date of September 15, 2020, was easy to maintain, it still had the following drawbacks: the controller was connected to the electrical control board via a cable, and the user's use was limited by the cable.

[0005] Therefore, in this utility model patent application, the applicant has carefully researched a wireless remote-controlled electric hoist to solve the above problems. Utility Model Content

This makes the application scenarios of the electric hoist no longer limited, providing users with a better user experience. Moreover, it provides safety protection for the electric hoist, preventing non-professionals from operating it, and effectively improving the professionalism of the electric hoist's use.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wireless remote-controlled electric hoist includes a housing, with an upper hook assembly at the upper end and a lower hook assembly at the lower end. A driver is located inside the housing on one side. A sprocket box is located in the middle of the housing, containing a chain assembly. A gearbox is located on the side of the sprocket box away from the driver, containing a reducer assembly. A brake is located inside the housing on the side of the gearbox away from the sprocket box. An electrical control board is located inside the housing on the side of the brake away from the sprocket box. A first end cover and a second end cover are detachably connected to the upper end of the housing.

[0009] It also includes a wireless controller, which is equipped with a main control unit and a first wireless communication unit, a display screen, a fingerprint reader and several control buttons respectively connected to the main control unit;

[0010] The electrical control board is connected to a second wireless communication unit for wirelessly connecting to the first wireless communication unit, and the electrical control board and the main control unit are wirelessly connected through the first wireless communication unit and the second wireless communication unit.

[0011] As a preferred embodiment, the first wireless communication unit and / or the second wireless communication unit is a Bluetooth module.

[0012] As a preferred embodiment, the fingerprint reader and the control buttons are located on different sides of the wireless controller.

[0013] As a preferred embodiment, the display screen and several control buttons are both located on the same side of the wireless controller.

[0014] As a preferred embodiment, the control buttons and display screen are all located on the front surface of the wireless controller, and the fingerprint reader is located on the rear surface of the wireless controller.

[0015] As a preferred embodiment, the second wireless communication unit is disposed on the outer surface of the first or second housing.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly uses a wireless controller to change the original wired connection to a wireless connection, eliminating the need for cables and freeing users from the constraints of cables. This makes the application scenarios of the electric hoist no longer limited, providing users with a better user experience. Moreover, fingerprint recognition is used to protect the electric hoist and prevent non-professionals from operating it, effectively improving the professionalism of the electric hoist.
