Description

Technical Field

[0001] The utility model relates to the technical field of telescopic doors, in particular to an electric telescopic door driving device. Background Art

[0002] Electric retractable doors are intelligent door products with automatic opening and closing functions. The characteristic of this door is that it can automatically open and close without human intervention, providing a convenient, efficient and safe entrance and exit solution. Electric retractable doors are widely used in commercial buildings, residential areas, office buildings, garages, airports, subway stations, hotels, hospitals and other places to meet the entrance and exit needs of different places.

[0003] According to the utility model patent with authorization announcement number: CN220599557U, a driving device for an electric telescopic door is disclosed, which relates to the technical field of telescopic doors. Its beneficial effects are: the driving motor can be driven to actively rotate through the first bevel gear and the second bevel gear, and the speed of the driving wheel can be controlled by the controller, thereby controlling the opening and closing speed of the telescopic door, so that the opening and closing of the electric telescopic door is more stable and reliable, and the operating efficiency and safety of the telescopic door are improved. The UPS backup power supply can provide a stable power supply for the driving motor and the controller in the event of power outage or unstable voltage, thereby ensuring the normal operation of the telescopic door, avoiding the telescopic door from being stuck or damaged due to power failure, and increasing the practicality of the device.

[0004] The driving mechanism is generally divided into: hydraulic drive, pneumatic drive, electrical drive and mechanical drive. Usually mechanical drive requires gear transmission, but multiple gears usually need to be oiled and maintained in order to reduce tooth surface wear, vibration, impact and noise.
