Power generation door hinge

Abstract

The invention provides a power generation door hinge, and belongs to the field of house decoration hardware. The power generation door hinge is characterized in that during an opening and closing process of a door, part of mechanical energy of the torque of the door is converted into electric energy through a piezoelectric effect to supply charging power to batteries of intelligent locks and the like; besides, the amount of generated power is in direct proportion to the using frequency, so that the cruising ability of the batteries of the intelligent locks and the like is greatly improved; andchanging and maintenance of the batteries are reduced or even omitted. Meanwhile, according to the power generation door hinge provided by the invention, vibration energy caused by building shaking,people walking and the like in an ambient environment can be converted when the door is opened or closed, so that additional battery charging power is provided. Meanwhile, the damping torque of the door during opening and closing can be effectively adjusted by the power generation hinge, so that the operation comfort of door opening and closing is adjusted. The power generation door hinge is especially applicable to hotels, intelligent houses and other application places.

Description

technical field [0001] The invention belongs to the field of home decoration hardware, and in particular relates to a power generation door hinge. Background technique [0002] Compared with traditional mechanical locks, smart locks such as fingerprint locks, magnetic card locks, IC card locks, electronic chip locks, and radio frequency locks have incomparable advantages in user identification, security, and user management. With the large-scale promotion and use of smart locks and smart access control systems, the safety and convenience of homes have been greatly improved. Generally speaking, various smart locks and access control systems need external power (such as batteries) to provide power to ensure their normal operation during use. Although the existing smart locks generally have deeply optimized their hardware, software and power management to reduce their power consumption to prolong the battery replacement interval and battery life of the lock, but limited by the...

AI Technical Summary

Problems solved by technology

Especially in the hotel industry, the frequency of use of locks is extremely high, so the replacement cycle of the lock battery is shorter. If the battery is not replaced in time, the lock will not work properly.

Therefore, in industries where a large number of smart locks are used, the battery power monitoring, replacement and maintenance will bring additional labor costs and expenses to the enterprise

At the same time, if the used batteries that are replaced are discarded or disposed of improperly, it will bring great pressure to environmental protection.

With the continuous development of battery technology, the continuous improvement of battery capacity and energy density prolongs the battery replacement time to a certain extent, but this problem cannot be completely solved
