Abstract
The disclosure provides a seat-bed dual-purpose support switching mechanism for a seat and a bearing device including a bearing support with rotary holders rotatably arranged on fixing holders on opposite sides of the bearing device, so that the bearing support can pivotably swing between a seat position and a carrycot position, and a switching assembly for the rotary holder to drive a locking member to be away from the fixing holder via a driving lever so that the bearing support is unlocked to pivotably swing, or to drive the locking member to be close to the fixing holder with the driving lever so that the bearing support is locked after a pivotal swing.
Claims18
A support switching mechanism for a bearing device, wherein:
- the bearing device includes a main frame body, and the support switching mechanism comprises:
- two fixing holders respectively fixed to opposite sides of the main frame body, at least one of the fixing holders having a seat mode positioning portion and a carrycot mode positioning portion being separated by an angle on the fixing holder;
- a bearing support provided, on opposite sides, with rotary holders corresponding to each of the fixing holders, each of the rotary holders being rotatably arranged on its corresponding fixing holder, and the bearing support being configured to pivotably swing between a seat position and a carrycot position as the rotary holders rotate;
- and
- a switching assembly disposed on at least one of the rotary holders and having a driving lever and a locking member connected to the driving lever,
- wherein, when the driving lever is pulled by an external force, the locking member is driven to move away from its corresponding fixing holder, so that the bearing support is unlocked and allowed to pivotably swing between the seat position and the carrycot position, and
- after the external force disappears, the locking member is driven to move towards its corresponding fixing holder to engage with one of the seat mode positioning portion and the carrycot mode positioning portion, so that the bearing support is locked.
A seat, comprising a bearing support, two fixing holders, and a switching assembly, wherein:
- at least one of the fixing holders has a seat mode positioning portion and a carrycot mode positioning portion being separated by an angle on the fixing holder;
- the bearing support is provided, on opposite sides, with rotary holders corresponding to each of the fixing holders, the rotary holders being rotatably arranged on its corresponding fixing holders, and the bearing support being configured to pivotably swing between a seat position and a carrycot position as the rotary holders rotate;
- and
- the switching assembly is disposed on at least one of the rotary holders, and comprises a driving lever and a locking member connected to the driving lever,
- wherein, when the driving lever is pulled by an external force, the locking member is driven to move away from its corresponding fixing holder, so that the bearing support is unlocked and allowed to pivotably swing between the seat position and the carrycot position, and
- after the external force disappears, the locking member is driven to move towards its corresponding fixing holder to engage with one of the seat mode positioning portion and the carrycot mode positioning portion, so that the bearing support is locked.
