Power-assisted seesaw

Abstract

The invention provides a power-assisted seesaw, and belongs to the technical field of body-building equipment. The seesaw comprises a seesaw body, a base plate and two seats, the seesaw body is made of a non-ferromagnetic material, and rotationally arranged on the two seats via a rotating shaft on a support block, the two seats are arranged on the pedestal in parallel, the seesaw body is internally provided with an installation cavity along the length direction, the left and right ends of the installation cavity are provided with first and second electromagnets respectively, a counterweight block which includes a permanent magnet is arranged in the installation cavity in a sliding way, the right end surface of the seesaw body is provided with a storage battery, the left end surface of theseesaw body is provided with a controller, the left and right ends in the lower side surface of the seesaw body are provided with first and second pressure sensors respectively, and the first and second pressure sensors and the first and second electromagnets are electrically connected with the storage battery via the controller. The counterweight block is additionally arranged in the seesaw body,so that the seesaw body can be played with by people in different weights.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, and relates to a power-assisted seesaw. Background technique [0002] The seesaw is a kind of physical fitness project that two people participate in. Two people sit on both ends of the seesaw. The gravity of the person is the driving force at the end of the seesaw, and the end of the landing is the resistance. The distance between the person and the fixed point of the seesaw is the force arm. , the acceleration of gravity causes one to go up and down, the acceleration of gravity of the higher one is greater than that of the lower one, so the higher one falls, and at the same time, the lower one is tilted up under the action of the principle of leverage, and so on. [0003] The existing seesaw is composed of a support point and a seesaw. According to the principle of leverage, two people with similar weights can achieve dynamic balance. However, it is common for an adult to take a child...

Problems solved by technology

[0003] The existing seesaw is composed of a support point and a seesaw. According to the principle of leverage, two people with similar weights can achieve dynamic balance. However, it is common for an adult to take a child to play on a seesaw. Due to the weight difference between the two sides If it is too large, the child will hang in the air, and the adult can't lift it up, losing the fun of playing, so it is only suitable for two people with similar weights, which improves the use conditions of the seesaw virtually.
