Description

Technical Field

[0001] This utility model relates to the field of physiotherapy bed technology, and in particular to a bed frame that links the back and sitting positions. Background Technology

[0002] As an essential space for human rest, the functionality and comfort of a bed are paramount. In existing adjustable bed frame designs, the backrest typically rises and falls independently, lacking a linkage mechanism with the sitting area. This design flaw can easily cause users to slide during the lifting process, or experience abdominal pressure due to an unnatural curve between the lower back and hips, requiring frequent active posture adjustments and impacting comfort. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a bed frame with a backrest and a sitting position that links the backrest and the sitting position. This allows the overall movement of the bed frame to better conform to the natural posture changes of the human body when sitting up, thereby avoiding awkwardness or discomfort during use, reducing the need for users to make adjustments, and significantly improving the comfort and convenience of lying down and getting up.

[0004] The technical solution of this utility model is as follows: A bed frame with backrest and seat linkage includes a bed frame, a backrest board and a seat board disposed on the bed frame, and an actuator for driving the backrest board to rotate relative to the seat board. The bed frame is provided with an upwardly inclined guide groove, and the backrest board is provided with backrest lifting rollers that can slide within the guide groove. The seat board is hinged to the backrest board, and when the backrest board is raised or lowered, it drives the seat board to slide relative to the bed frame.

[0005] With the above technical solution, when the backrest is raised under the action of the actuator, the backrest lifting rollers slide in the guide groove. The guide groove can play a guiding role and make the backrest stable when raised. At the same time, the backrest will drive the seat bed board to slide, realizing the linkage between the backrest and the seat bed board. This makes the overall movement of the bed frame more in line with the natural posture changes of the human body when sitting up, thereby avoiding awkwardness or discomfort during use, reducing the need for users to make adjustments, and significantly improving the comfort and convenience of lying down and getting up.

[0006] A further feature of this invention is that the bed frame is also provided with an extension bed board and a leg bed board, the extension bed board being stored under the leg bed board, and the extension bed board sliding synchronously with the seat bed board.

[0007] With the above-mentioned further configuration, when the backrest is raised, the extension bed board is stored under the legrest bed board. When the backrest is raised, the seat bed board slides and drives the extension bed board to slide, so that the extension bed board moves out of the legrest bed board and fills the gap between the seat bed board and the legrest bed board.

[0008] A further feature of this invention is that the bed frame is provided with a sliding frame that can slide relative to it, the extension bed board and the seat bed board are both installed on the sliding frame, the extension bed board is set lower than the seat bed board, the sliding frame is provided with seat sliding rollers, and the bed frame is provided with a transverse sliding groove along its length, and the seat sliding rollers slide in the transverse sliding groove.

[0009] With the above-mentioned further configuration, the structure is simple and easy to install. The extension bed board and the seat bed board are installed on the sliding frame with screws. When the seat bed board moves under the drive of the back bed board, it drives the sliding frame to move. The movement of the sliding frame drives the extension bed board to move, which has good linkage. Furthermore, through the cooperation of the seat board sliding rollers and the transverse sliding groove, the sliding of the seat bed board and the extension bed board is stable and smooth.

[0010] A further improvement of this invention is that: two guide grooves are provided, one on each side of the bed frame; two back panel lifting rollers are also provided, each slidingly disposed in its corresponding guide groove; and the two back panel lifting rollers are connected by a flipping roller.

[0011] The above-mentioned further design improves the stability of the backrest bed board during lifting and lowering, ensuring smooth lifting and avoiding structural deformation caused by single-point stress.

[0012] A further feature of this invention is that the lower end face of the backrest bed board is provided with a connecting plate, the actuator includes a cylinder and a piston rod, the cylinder is mounted on the bed frame, the piston rod is connected to the connecting plate, the flipping roller passes through the connecting plate, and the extension and retraction of the piston rod can drive the backrest bed board to rise and fall.

[0013] The above-mentioned further configuration facilitates the connection between the actuator and the backrest board, enabling the backrest board to adjust its angle relative to the sitting board.

[0014] A further feature of this invention is that the lower end surface of the backrest bed board is provided with a support plate, which is connected to the flipping roller.

[0015] Further improvements are made by adopting the above-mentioned design to enhance the stability of the flipping roller. The support plate is provided with through holes, through which the flipping roller passes. Multiple support plates can be installed.

[0016] A further improvement of this invention is that the backrest board and the seat board are hinged together.

[0017] By adopting the above-mentioned further settings, while adjusting the angle, it is ensured that the connection between the backrest and the seat is firm and reliable.

[0018] A further feature of this invention is that the lower end of the backrest bed board is provided with support feet, which support the bed frame after the backrest bed board is lowered.

[0019] With the above-mentioned further configuration, the backrest bed board can be positioned. When the backrest bed board falls, the support feet contact the bed frame, which indicates that the backrest bed board has descended to the correct position and the actuator stops. The support feet can also provide support, making the backrest bed board more stable and secure. Attached Figure Description
