[0015] Referring to Figures 1-2, according to an embodiment of the present invention, a rechargeable lantern hanging lifting device is provided, including a lifting assembly, the lifting assembly including a shell 5, a motor 10, a rechargeable battery 11 and a PCB board 4 are arranged in the shell 5, the PCB board 4 has a battery power detection unit and an automatic descent control unit, the battery power detection unit is used to detect the remaining power of the rechargeable battery 11, the battery power detection unit and the motor 10 are both communicatively connected to the automatic descent control unit, the rechargeable battery 11 provides power to the motor 10, the output shaft of the motor 10 is connected to the cable reel 12 to be able to control the rotation of the cable reel 12, the top of the shell 5 has a through hole, the cable reel 12 is wound with a rope 1, one end of the rope 1 is connected to the cable reel 12, and the other end passes through the through hole and is connected to the fixing device at the hanging place, and the bottom end of the shell 5 is connected to the lantern. An independent lifting component is connected to a fixing device using a rope, for example, the rope is fixed to the eaves of a house. The lifting movement of the lifting component is achieved by retracting / releasing the rope, thereby achieving the lifting and lowering of the lantern connected to the lifting component, making it convenient to hang the lantern and avoiding the operator from having to climb up to hang the lantern. The danger level is reduced and the hanging is convenient and quick. The equipment is simple and easy to install after purchase. It only needs to be fixedly connected to the eaves of the house and can be operated by one person. The equipment itself can be raised and lowered, making it convenient for maintenance. In addition, a rechargeable battery 11 is used to power the lifting component, eliminating the complex problem of rewiring and reducing the occurrence of safety accidents. In addition, when the battery power detection unit detects that the capacity of the rechargeable battery 11 is lower than the set value, a signal is sent to the automatic descent control unit, which controls the motor 10 to operate and lower the lifting component to allow the user to replace the battery. This can effectively avoid the risk of the lifting component being unable to descend due to battery power shortage.

[0016] Specifically, the motor, rechargeable battery, battery capacity detection unit, and automatic lowering control unit are all connected to the PCB board 4. The PCB board 4 is also connected to a wireless receiving device for receiving the raising / lowering signal. Preferably, the wireless receiving device is an infrared receiver 13.

[0017] Specifically, the top of the housing is provided with a top cover 2. The split structure makes the equipment assembly and maintenance more convenient.

[0018] In a specific embodiment, the rechargeable lantern hanging and lifting device further includes a middle frame assembly located within the housing. The middle frame assembly includes a first middle frame 8 and a second middle frame 9 spaced apart. Two wire fixing posts 7 are disposed between the first middle frame 8 and the second middle frame 9. The rope 1 can move under the clamping action of the two wire fixing posts 7. The clamping action of the wire fixing posts 7 effectively prevents the risk of the rope 1 becoming tangled.

[0019] Specifically, the first middle frame 8 and the second middle frame 9 are detachably connected to fix the motor 10 , the top cover 2 and the bottom cover 14 .

[0020] Specifically, a PCB insulating pad 6 is provided between the PCB board 4 and the middle frame assembly to isolate the PCB board 4 from the middle frame assembly.

[0021] In a specific embodiment, the rechargeable lantern hanging and lifting device also includes a protective device, which includes a protective cover body 18 with a hollow structure, and the protective cover body 18 includes a bottom wall 19 and a side wall extending upward along the bottom wall 19. The top of the protective cover body 18 is an open structure, and the bottom wall 19 has a threading hole. The rope 1 passes through the threading hole and is connected to the fixing device at the hanging place. A one-way wire locker 20 is provided between the bottom wall 19 and the top of the shell 5, and the one-way wire locker 20 can slide unidirectionally along the rope 1.

[0022] Specifically, a rubber pad 3 is provided between the top cover 2 and the PCB board 4 to provide better isolation.

[0023] Specifically, the fixing device at the hanging place is a circular ring or semicircular ring hook fixed at the eaves, or other fixing devices that can be used for hanging.

[0025] In a specific embodiment, the rope 1 is a steel rope.

[0026] In a specific embodiment, the internal space of the shell 5 is divided into a motor compartment and a battery compartment. The bottom end of the shell 5 has a bottom cover 14 and a battery cover 15. The bottom cover 14 is used to seal the motor compartment, and the battery cover 15 is used to seal the battery compartment.

[0027] Specifically, the battery cover 15 is fixedly connected to the housing 5 by screws 17 .

[0028] During use, when it is necessary to hang a lantern, the first step is to activate the remote control's down button. After receiving the signal, the infrared receiver 13 controls the automatic descent control unit to descend. When the device descends to the appropriate position, it stops descending. The second step is to hang the lantern on the hook 16 of the lifting component. The third step is to activate the remote control's up button. When the device rises to the appropriate position, it stops descending. The battery power detection unit constantly detects the capacity of the rechargeable battery 11. When the battery capacity is lower than the set value, the battery power detection unit sends a low-battery signal to the automatic descent control unit. After receiving the signal, the automatic descent control unit controls the motor 10 to rotate and descend. When the motor 10 descends for a preset time, it stops, reminding the user to replace the rechargeable battery 11.
