Title:
TORQUE TRANSFER MECHANISM, ELECTRIC STARTING DEVICE, ENGINE AND GARDEN TOOL
Document Type and Number:
WIPO Patent Application WO/2021/032044
Kind Code:
A1
Abstract:
A torque transfer mechanism, an electric starting device, an engine and a garden tool. The torque transfer mechanism comprises a first transmission member (10), a second transmission member (30), and an elastic buffer member (20) located between the first transmission member (10) and the second transmission member (30). The elastic buffer member (20) is configured to buffer and transfer the torque of the first transmission member (10) to the second transmission member (30). The torque is transferred by using the elastic buffer member (20), so that the torque of the first transmission member (10) is temporarily buffered by the elastic buffer member (20) in the process of the torque transfer, and then the torque is transferred to the second transmission member (30) by means of the elastic buffer member (20), solving the problem in the prior art that hooks connected between a gear and a spiral spring and between the spiral spring and a ratchet wheel are easy to break. Furthermore, the elastic buffer member has a simple manufacturing process, a low cost, low transfer noise, and is easy to assemble and disassemble, without the need for additionally installing a security protection component.
