A trekking pole based on piezoelectric effect for energy storage

Abstract

The invention discloses a trekking pole for storing energy based on the piezoelectric effect, which includes a handle, a pole and a battery module; the pole includes a cylindrical upper pole, a shock absorbing spring and a lower pole; The middle part of the part is provided with a shoulder, the upper end of the damping spring is fixed on the upper rod part, and the lower end is fixed on the shoulder; the upper end of the lower rod part is inserted into the inner side of the upper rod part; A piezoelectric material layer is fixedly arranged above the lower pole, and the piezoelectric material layer is connected to the battery module through wires. By adopting the above-mentioned technical solution, the trekking pole of the present invention based on the piezoelectric effect for energy storage can compress the shock-absorbing spring every time the handle is pressed down during walking, thereby causing the upper rod to move down. The compression spring is also compressed and exerts a downward pressure on the impact cylinder, and this downward pressure is transmitted to the piezoelectric material layer, thereby generating an electric current that is transmitted along the wires to the battery module for charging.

Description

technical field

[0001] The invention relates to a trekking pole for energy storage based on piezoelectric effect, which belongs to the technical field of outdoor sports equipment. Background technique

[0002] Trekking poles are auxiliary equipment used in mountaineering. Trekking poles can bring many benefits to outdoor mountaineering activities, such as improving the stability of walking and reducing the burden on the legs. According to research, using trekking poles when walking can reduce at least 22% of the force applied to muscle joints such as legs and knees, making the legs feel more comfortable, and using two trekking poles at the same time can provide better balance. In addition, it can also be used as a pole for building a canopy with a tarp. Because trekking poles are used for outdoor sports, and outdoor sports have certain dangers, especially when hiking in the mountains far away from the city, not only are you prone to encounter dangers from wild animals, but...
