Aofei Jiutong has obtained a patent for a deceleration device for smart doors, which enables the power structure required to automatically open hinged doors without hinges.

News from the financial industry on September 10, 2024. Intellectual property information from Tianyancha shows that Aofei Jiutong Intelligent Technology (Changzhou) Co., Ltd. has obtained a project called \”a deceleration device for smart doors\” \”, authorization announcement number CN221683541U, application date is December 2023.

The patent abstract shows that the utility model discloses a deceleration device for a smart door, which includes a mounting bottom plate. A lower shell is provided in the middle of the top of the mounting bottom plate, and an upper shell is set at the top of the lower shell. The middle part between the housing and the upper housing is provided with a first rotating shaft, a second rotating shaft, a third rotating shaft and a fourth rotating shaft. The surface of the first rotating shaft is fixedly provided with a first gear. This utility model is a deceleration device for an intelligent door. , by placing the reduction gear at Inside the top beam of the door frame, the lower part of the door frame only needs to install a ground shaft with a simple structure and strong load-bearing capacity, so as to realize the power structure required for automatic opening of the hinge-less swing door, and the reduction device uses a worm, worm gear and several gear transmission combinations The transmission mode can effectively reduce the height and size of the entire deceleration device while ensuring the deceleration effect, which can better adapt to the needs of automatic doors with narrow door frames, and can increase the service life of the deceleration device.
