Description

Turnover hood Technical Field The invention relates to the field of massage equipment, in particular to a turnover hood. Background In order to increase the privacy of the massage armchair, there is an increasing need to fit the head cover on the massage armchair. At present, most of the head covers assembled on the massage chairs are adjusted by adopting a manual overturning mode, so that the operation is inconvenient, and an electric direct-drive driving mode is adopted, because the dead weight of the head covers is large, a large torque is required, and an electric direct-drive mechanism capable of being assembled in a limited space of the massage chairs cannot meet the torque required by the overturning stability of the head covers. Therefore, if the head cover adopts an electric direct drive mode, the safety and the stability are poor. Disclosure of Invention The invention aims to solve the technical problem of providing a turnover head cover, which improves the stability and safety of the turnover head cover. In order to solve the technical problems, the invention adopts the following technical scheme: a turnover head cover comprises a head cover body arranged at the upper end of a massage chair back frame, a driving mechanism, a first connecting rod and a hinged frame connected with the head cover body; The driving mechanism is arranged at the upper end of the massage chair back frame and is arranged along the up-down direction of the massage chair back frame; The first end of the hinge frame is hinged with the movable end of the driving mechanism through the first connecting rod, the second end of the hinge frame is hinged with the first end of the massage chair back frame, and the first end and the second end of the hinge frame are arranged at intervals; When the first end of the hinge frame is lifted along with the movable end of the driving mechanism, the hinge frame rotates around the first end of the massage chair back frame. In order to solve the technical problems, the invention adopts another technical scheme that: A turnover head cover comprises a head cover body, a driving mechanism, a first connecting rod, a hinged frame, a second connecting rod and a third connecting rod, wherein the head cover body is arranged at the upper end of a massage chair back frame; The driving mechanism is arranged at the upper end of the massage chair back frame and is arranged along the up-down direction of the massage chair back frame; The first end of the hinge frame is hinged with the movable end of the driving mechanism through the first connecting rod, the second end of the hinge frame is hinged with the first end of the massage chair back frame, and the first end and the second end of the hinge frame are arranged at intervals; When the first end of the hinged frame is lifted along with the movable end of the driving mechanism, the hinged frame rotates relative to the upper end of the massage chair back frame; the second end of the hinge frame is hinged with the first end of the massage chair back frame through the second connecting rod, and the third end of the hinge frame is hinged with the second end of the massage chair back frame through the third connecting rod; The first end of the hinge frame and the third end of the hinge frame are both positioned at the horizontal part of the hinge frame, and the second end of the hinge frame is positioned at the vertical part of the hinge frame. The invention has the beneficial effects that the hinge frame is driven to overturn around the massage chair back frame by the driving mechanism and the first connecting rod, so that the head cover body can be stably overturned. Due to the arrangement of the first connecting rod, the second connecting rod and the third connecting rod, multi-point position support is provided for the head cover body, the torque required by the driving mechanism when the head cover body is overturned is reduced, and the safety and stability of the head cover body when the head cover body is overturned are improved.
