A door-opening generator

Abstract

The invention relates to a door-opening power generating device. The door-opening power generating device comprises a door, a door frame, a support, a transmission shaft, a ratchet wheel, at least one first pawl, a gear, an electric generator, a storage battery, a rope and a coil spring; one end of each first pawl is connected with the transmission shaft, and the other end of each first pawl is provided with a first plane and a first circular-arc surface; multiple ratchet teeth are arranged on the ratchet wheel along the periphery, each ratchet tooth comprises a ratchet tooth plane and a ratchet tooth circular-arc surface, each ratchet tooth plane is used for being matched with the corresponding first plane in a contact manner, and each ratchet tooth circular-arc surface is used for being matched with the corresponding first circular-arc surface in a contact manner; wheel teeth are arranged on the ratchet wheel along the periphery, the wheel teeth are used for being meshed with the gear, and the gear is fixedly connected with a rotating shaft of the electric generator; one end of the rope and the door frame are fixed, the other end of the rope is connected with the transmission shaft, and the rope is wound on the transmission shaft multiple circles; and the inner end of the coil spring is connected with the transmission shaft, and the outer end of the coil spring is connected with the support. The door-opening power generating device is capable of achieving automatic door closing, simple in structure, low in transmission noise and small in door closing resistance.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a door-opening power generation device. Background technique [0002] In the process of opening and closing the door, there will be energy consumption, and the door opening power generation device is a device that converts the mechanical energy in the process of opening the door into electrical energy. [0003] An existing door-opening power generation device is: use the rack and pinion installed on the door and the door frame to drive the gear installation shaft to rotate, and then use the intermediate mechanism to convert the rotation of the gear installation shaft into the unidirectional rotation of the generator shaft, thereby realizing power generation. . The disadvantages of the above-mentioned door-opening power generation device are: 1. The use of a rack and pinion structure results in a complex structure and increased transmission noise; 2. When closing...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned door-opening power generation device are: 1. The use of a rack and pinion structure results in a complex structure and increased transmission noise; 2. When closing the door, it needs to resist the meshing resistance from the rack and pinion, which is relatively large; close the door
