Problems solved by technology
The problem with the existing spring operating mechanism energy storage device is that the power transmission between the motor and the energy storage shaft is realized through the sprocket and gear, and the transmission process of the sprocket and gear is bidirectional. During the energy-saving process, when the motor drives the closing spring to store energy, the closing spring will also give the rotor of the motor a counter-rotating force through the sprocket and gear, and the motor needs a lot of power to complete the energy storage of the energy storage spring. process, which requires the use of high-power motors, the use of high-power motors increases the production cost of the product; at the same time, when the closing spring releases energy, the rotation of the energy storage shaft will also be transmitted to the rotor of the motor through the chain and gears. Drive the rotor to rotate, the idling of the rotor not only increases energy consumption, but also reduces the service life of the motor

The invention relates to a transmission mechanism and a spring operating mechanism energy storage apparatus using the same. The transmission mechanism comprises a cam shaft and a connecting lever shaft, wherein the two shafts are arranged in parallel. At least two transmission connecting levers are assembled at the connecting lever shaft by a unilateral bearing; and transmission cams that are arranged by corresponding to all transmission connecting levers one by one are fixedly arranged at the cam shaft at intervals around the peripheral direction, wherein the transmission cams are used for continuously pushing the corresponding transmission connecting levers in sequence when the connecting lever shaft rotates so as to enable the transmission connecting levers to drive the connecting lever shaft to make rotation. According to the invention, the transmission mechanism that can make transmission continuously in a unidirectional mode and the spring operating mechanism energy storage apparatus using the transmission mechanism are provided.
