Hinge

Abstract

A hinge comprises an upper shell, a lower shell, an upper blade, a lower blade, a hinge shaft, a driving motor, a planetary gearbox, a hinge clutch device and the like. The components of the hinge are reasonably arranged fittingly, the hinge is electrically driven to be opened and closed smoothly, in the opening and closing process of the hinge, automatic separation and reunion can be realized when the hinge encounters resistance, then the hinge stops rotating, and damage of the driving motor is avoided. The hinge is simple in integral structure, and is electrically driven to be opened and closed smoothly and flexibly. Cost of the components is low, installation is convenient, and the service life of the hinge is long.

Description

technical field [0001] The invention relates to a movable connection device, in particular to a hinge. Background technique [0002] A hinge is a device for connecting or turning so that a door, cover or other swinging parts can turn, and it usually consists of a pair of metal leaves connected by pins. At present, none of the existing hinges has an electrical circuit structure, cannot be opened and closed automatically, and is inconvenient to use; a small number of doors with automatic opening and closing functions realize automatic opening and closing through the linkage linkage of the door closer. The device cannot be integrated with the door, and needs to be installed and debugged separately, which not only affects the appearance, but also takes time and labor, and the cost is also high. Chinese patent ZL200920286018.7 discloses an electric hinge, which includes two hinge blades, one hinge blade of the two hinge blades is fixed on a lower housing, and the other hinge bla...

AI Technical Summary

Problems solved by technology

For this kind of electric hinge, the central shaft on the planet carrier is directly fixedly connected with the output shaft of the motor, and the planetary gear is meshed with the upper and lower casings for transmission, and the torque is large. When the opening and closing of the hinge is blocked, the motor cannot be automatically clutched and shut down, and it is easy to be damaged. The motor will seriously damage the entire device, which is very inconvenient to use; the shell, planetary carrier, and planetary gear must be molded and cast, with a large amount of cutting and very high precision requirements, and attention must also be paid to eliminating casting or welding defects and internal Stress, if there is an error in one item, the whole will not be able to be assembled, and the cost will be very high; and the overall size of this electric hinge is large, and there are many external structures, which will affect the appearance
