Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to an intelligent limiting device for hinges. Background Technology

[0002] A hinge is a connecting component mainly used in household windows, doors, cabinets and other places that need to be rotated and opened. Different types of hinges can be used in different usage scenarios, and their opening and closing angles are also different.

[0003] The announcement number CN118309335A discloses an intelligent limiting device for a hinge, including a first mounting plate and a second mounting plate. The top end of the second mounting plate is fixedly provided with a mounting rod, and the top end of the first mounting plate is fixedly provided with two extension plates. One end of each extension plate extends toward the side where the second mounting plate is located and is sleeved on the outer end of the mounting rod through a rotating shaft. A transmission shaft is provided between the two extension plates, and a speed sensor is installed on the sleeve.

[0004] In use, hinges are widely used in connecting movable parts such as doors and windows. Traditional hinges can only achieve simple rotational connection functions, lacking precise control and intelligent adjustment capabilities for the rotation angle. In practical use, such as the opening and closing of doors and windows, the inability to limit their maximum opening may lead to collisions with walls and damage, or excessive opening and closing due to external forces such as wind, affecting their service life and safety. Moreover, in some special scenarios, such as when it is necessary to adjust the opening and closing angle of doors and windows according to different time periods or environmental conditions, existing devices can only limit the hinge position, which is difficult to control. Therefore, we propose an intelligent hinge limiting device. Utility Model Content
