Abstract

The invention relates to a door-opening power generation device. The door-opening power generation device includes: door, door frame, bracket, transmission shaft, ratchet, at least one first pawl, gear, generator, battery, rope and coil spring; one end of the first pawl is connected to the transmission shaft, and the first pawl The other end is provided with a first plane and a first arc surface; the ratchet is provided with several ratchet teeth along the circumference, each ratchet tooth includes a ratchet plane and a ratchet arc surface, and the ratchet plane is used to communicate with the first A plane contact fit, the arc surface of the ratchet tooth is used for contact fit with the first arc surface; the ratchet wheel is provided with gear teeth along the circumference, the gear teeth are used for meshing with the gear, and the gear is fixedly connected to the rotating shaft of the generator; one end of the rope is connected to the rotating shaft of the generator. The door frame is fixed, the other end of the rope is connected to the transmission shaft, and the rope is wound around the transmission shaft several times; the inner end of the coil spring is connected to the transmission shaft, and the outer end of the coil spring is connected to the bracket. The door-opening power generation device of the present invention can automatically close the door and has a simple structure, low transmission noise, and low 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...
