Patent number: 11675033Abstract: The present invention provides a damping mechanism comprising a first member comprising a base section, a resilient damping section and an enclosed chamber defined by the base section and an inner surface of the resilient damping section. The resilient damping section is centered about a rotation axis and the enclosed chamber is provided radially inward of the resilient damping section and configured to accommodate a deformation of the resilient damping section. A second member is attached pivotably to the base section of the first member to rotate around the rotation axis relative to the base section. A damping protrusion extends from the second member toward the resilient damping section. The resilient damping section comprises an outer surface facing away from the enclosed chamber which is configured to be engaged with the damping protrusion to produce the deformation of the resilient damping section and provide a damping to the rotation of the second member relative to the base section.Type: GrantFiled: September 11, 2020Date of Patent: June 13, 2023Assignee: Koninklijke Philips N.V.Inventors: Deyi Qiu, Junbo Zhang
