Driving mechanism with compound massage actions
The present application discloses a driving mechanism with compound massage actions, including a bracket, on which a first, second, and third massage portions are slidably mounted. The bracket has a power mechanism inside, to which the first massage portion is eccentrically and rotatably connected. The power mechanism includes a connecting rod, which connects to a first connecting rod assembly at one end and a second connecting rod assembly at the other end. The first and second connecting rod assemblies are rotatably connected to the second and third massage portions, respectively. A matching angle adjustment structure is provided at the connection between the connecting rod and the second connecting rod assembly. The second and third massage portions reciprocate synchronously/asynchronously when the connecting rod rotates counterclockwise/clockwise. The driving mechanism performs different compound massage actions on a body part in the first and second massage chambers to improve massage comfort and effect.
