[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model discloses an outdoor synchronous belt forced-drive lifting structure, comprising a car, a drive motor, and a steel belt. The steel belt is connected to both the car and the drive motor via guide wheel assemblies, enabling the drive motor to drive the car in lifting motion via the steel belt. One end of the steel belt is connected to the lower end of the car, and the other end passes around the drive shaft of the drive motor and connects to the upper end of the car. Furthermore, a protrusion is provided in the middle of the steel belt, and serrations are provided on both sides of the protrusion. Based on this outdoor synchronous forced-drive lifting structure, a lifting structure that uses a shaftless and counterweightless forced-drive system for the vertical movement of the car greatly optimizes the structure of outdoor lifting equipment and increases the design versatility of lifting equipment. In addition, the protrusion in the middle of the steel belt and the serrations on both sides of the protrusion solve problems such as lateral deviation, instability, and slippage between the steel belt and the drive motor and guide wheel assemblies, thereby improving the market competitiveness of the equipment.

[0014] In addition, the lifting equipment has an openable door on at least one side of the car, or even on all four sides of the car, to achieve the special requirement of a shaftless lifting equipment with doors on all four sides of the car.

[0015] In addition, the protrusions on the steel belt are set along the length of the steel belt and are the same length as the steel belt, so that the entire steel belt can be locked with the drive motor or guide wheel assembly to prevent the steel belt from running off-track.

[0016] In addition, the guide wheel assembly includes several guide wheels, which are respectively located beside the drive motor, at the top and bottom of the open-air elevator device. These guide wheels are used to assist the steel belt in driving the car to move up and down under the drive of the drive motor.

[0017] This time, a groove is set in the middle of the guide wheel, and serrations are set on both sides of the groove. The groove engages with the protrusions on the steel belt, and the serrations mesh with the serrations on the steel belt. Through the meshing connection between the guide wheel and the serrations on the steel belt, the millimeter-level positioning of the car is achieved, solving the slippage problem between the ordinary steel belt and the guide wheel and drive motor.

[0018] Furthermore, the lifting structure is equipped with a mounting housing, within which the drive motor, steel belt, and guide wheel assembly are all housed. This housing effectively shields and protects these components. Attached Figure Description

[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The outdoor synchronous belt forced-drive lifting structure in this embodiment is suitable for elevator equipment installed outdoors, and can realize the up and down movement of outdoor elevator equipment without counterweight.

[0023] like Figure 1 , 2 As shown, the outdoor synchronous belt forced drive lifting structure includes a car 10, a mounting housing 20, a drive motor 30, a steel belt 40, and a guide wheel assembly.

[0024] The car 10 is the main body of an outdoor lifting device without a shaft. Additionally, at least one side of the car 10 has an openable door. In this embodiment, all four sides of the car 10 have openable doors 11, providing a four-door car body.

[0025] The mounting housing 20 is located near the car 10 and can be attached to the wall next to the car 10. The mounting housing 20 has a hollow structure, which provides installation space for the drive motor 30, steel belt 40 and guide wheel assembly.

[0026] The drive motor 30 is installed inside the mounting housing 20, located in the middle of the entire lifting device. The drive motor 30 is a worm gear motor with an output shaft.

[0027] The guide wheel assembly includes several guide wheels, wherein guide wheel 51 and guide wheel 52 are respectively located on the side of drive motor 30, guide wheel 53 is located at the top position inside the mounting housing 20, and guide wheel 54 is located at the bottom position inside the mounting housing 20.

[0028] One end of the steel belt 40 is connected to the upper end of the car 10. The other end of the rope first passes over the guide wheel 53 on the top of the mounting housing 20, then passes over the guide wheel 52 on one side of the drive motor 30, then connects to the drive shaft of the drive motor 30, passes over the drive shaft, then passes over the guide wheel 51 on the other side of the drive motor 30, and finally passes over the guide wheel 54 at the bottom of the mounting housing 20 and connects to the lower end of the car 10.

[0029] In addition, a protrusion is provided on the steel belt 40 along its length, the length of which is the same as that of the steel belt 40, and serrations are provided on both sides of the protrusion. The guide wheel assembly has the same structure, with a groove in the middle of the guide wheel that engages with the protrusion on the steel belt 40. Serrations are also provided on both sides of the groove, which mesh with the serrations on the steel belt 40. The engagement of the groove and the protrusion between the steel belt 40 and the guide wheel prevents the steel belt 40 from deviating, and the meshing of the serrations achieves precise positioning between the two, thereby achieving millimeter-level positioning of the steel belt 40.

[0030] The outdoor synchronous belt forced-drive lifting structure according to the above embodiment includes a car, a drive motor, and a steel belt. The steel belt is connected to the car and the drive motor respectively through a guide wheel assembly, enabling the drive motor to drive the car to move up and down via the steel belt. One end of the steel belt is connected to the lower end of the car, and the other end passes around the drive shaft of the drive motor and is connected to the upper end of the car. Furthermore, a protrusion is provided in the middle of the steel belt, and serrations are provided on both sides of the protrusion. Based on this outdoor synchronous forced-drive lifting structure, a lifting structure that uses a shaftless and counterweightless forced-drive system for the up-and-down movement of the car greatly optimizes the structure of outdoor lifting equipment and increases the design diversity of lifting equipment. In addition, the protrusion in the middle of the steel belt and the serrations on both sides of the protrusion solve problems such as lateral deviation, instability, and slippage between the steel belt and the drive motor and guide wheel assembly, thereby improving the market competitiveness of the equipment.

[0031] In addition, the lifting equipment has an openable door on at least one side of the car, or even on all four sides of the car, to achieve the special requirement of a shaftless lifting equipment with doors on all four sides of the car.

[0032] In addition, the protrusions on the steel belt are set along the length of the steel belt and are the same length as the steel belt, so that the entire steel belt can be locked with the drive motor or guide wheel assembly to prevent the steel belt from running off-track.

[0033] In addition, the guide wheel assembly includes several guide wheels, which are respectively located beside the drive motor, at the top and bottom of the open-air elevator device. These guide wheels are used to assist the steel belt in driving the car to move up and down under the drive of the drive motor.

[0034] This time, a groove is set in the middle of the guide wheel, and serrations are set on both sides of the groove. The groove engages with the protrusions on the steel belt, and the serrations mesh with the serrations on the steel belt. Through the meshing connection between the guide wheel and the serrations on the steel belt, the millimeter-level positioning of the car is achieved, solving the slippage problem between the ordinary steel belt and the guide wheel and drive motor.

[0035] Furthermore, the lifting structure is equipped with a mounting housing, within which the drive motor, steel belt, and guide wheel assembly are all housed. This housing effectively shields and protects these components.

[0036] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
