This gap can easily cause other items such as pillows to fall out, causing inconvenience to the user. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bed frame with a backrest lifting and retraction function, which avoids the problem of items at the head of the bed falling off after the backrest is lifted.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A bed with a backrest lifting and retraction function, characterized in that it includes a fixed base, a sliding frame, a bed frame, and a backrest lifting actuator; The sliding frame is slidably fitted onto the fixed base. The bed frame is fixedly mounted on the sliding frame and has a rotatable backrest. A rearward pull rod is provided between the backrest and the fixed base on the side corresponding to the headboard. The back lift actuator is located between the back frame and the sliding frame, driving the back frame to rotate up and down while simultaneously moving the sliding frame back and forth in conjunction with the rearward pull rod.

[0006] Preferably, the fixed base has a sliding groove extending forward and backward, and the sliding frame includes a mounting frame and a roller assembly disposed on the mounting frame, the roller assembly cooperating with the sliding groove.

[0007] Preferably, the bed frame further includes a hip support, a leg support, and a foot support. The hip support is fixed to a sliding frame, the back support and the leg support are rotatably connected to the front and rear sides of the hip support, respectively, and the foot support is rotatably connected to the leg support. A leg lifting actuator is provided between the leg frame and the sliding frame, and a support link is provided between the foot frame and the sliding frame.

[0010] The advantages of this utility model are: 1. When the backrest lift actuator extends, it causes the backrest frame to rotate upward, making it easier for the user to get up or lean back. At the same time, it can work with the rear pull rod to move the entire sliding frame towards the head of the bed, reducing the gap between the backrest frame and the headboard and preventing items placed at the head of the bed from falling between the backrest frame and the headboard. Conversely, when the backrest lift actuator retracts, it causes the backrest frame to rotate downward, and at the same time, the rear pull rod pushes the sliding frame towards the foot of the bed, so that the bed returns to the flat position. 2. With the fixed base, the bed can be placed directly on the ground for use on the ground. Attached Figure Description

A rearward pull rod 5 is provided between the backrest frame 21 and the fixed base 1 on the side corresponding to the headboard. The backrest lifting actuator 4 is located between the backrest frame 21 and the sliding frame 3, driving the backrest frame 21 to rotate up and down, while simultaneously moving the bed frame 2 back and forth in conjunction with the rearward pull rod 5.

[0015] The fixed base 1 includes a quadrilateral frame structure 11 and a connecting rod 12 disposed in the frame structure 11. The frame structure 11 has sliding grooves 111 extending back and forth on the two inner side walls. The sliding frame 3 includes a mounting frame and a roller assembly disposed on the mounting frame. The roller assembly cooperates with the sliding grooves 111 to enable the sliding frame 3 to slide back and forth on the fixed base 1.

[0016] The mounting frame structure includes two parallel support beams 31 on the left and right sides and multiple support rods 32 between the two support beams 31. The roller assembly has four sets, which are located at the front and rear positions of the two support beams 31 respectively.

[0017] The roller assembly includes a connecting seat 34 disposed on the support rod 32 and a roller 33 disposed on the connecting seat 34.

[0018] The bed frame 2 also includes a hip support 22, a leg support 23, and a foot support 24. Each of the back support 21, hip support 22, leg support 23, and foot support 24 includes left and right side panels 25 and a rod 26 positioned between the two side panels 25. The left and right ends of the hip support 22 are bolted to the sliding frame 3. The side panels 25 of the back support 21 and the side panels 25 of the leg support 23 are rotatably connected to the front and rear sides of the side panels 25 of the hip support 22 via pins. The side panels 25 of the foot support 24 are rotatably connected to the side panels 25 of the leg support 23.

[0019] A leg lifting actuator 6 is provided between the leg frame 23 and the sliding frame 3, and a support link 9 is provided between the foot frame 24 and the sliding frame 3. When the leg lifting actuator 6 extends, it can lift the leg frame 23 towards the end of the bed foot, and at the same time lift the foot frame 24. The support link 9 can support the lifted foot frame 24 to ensure the overall stability of the bed frame 2.

[0020] Both the back lift actuator 4 and the foot lift actuator 6 are electric actuators. The motor mount of the back lift actuator is rotatably connected to the rod 26 in the back frame 21 via a connecting seat, and the actuator is rotatably connected to the support rod 32 in the sliding frame 3 via a connecting seat. Similarly, the motor mount of the foot lift actuator 6 is rotatably connected to the support rod 32 in the sliding frame 3 via a connecting seat, and the actuator is rotatably connected to the rod 26 in the leg frame 23 via a connecting seat.

[0021] The end of the rearward pull rod 5 near the head of the bed is rotatably connected to the connecting rod 12 of the fixed frame via a connecting seat, and the front end is rotatably connected to the rod 26 in the back frame 21 via a pin.

[0022] The rear end of the support link 9 is rotatably connected to the support beam 31 in the sliding frame 3 via a pin, and the front end is rotatably connected to the rod 26 in the foot frame 24 via a pin.

[0023] A stop bar 8 is provided on the side of the backrest 21 corresponding to the head of the bed and the side of the footrest 24 corresponding to the foot of the bed. The stop bar 8 can prevent items from falling off the bed.

[0024] A surrounding panel 7 is provided on the outer side of the back frame 21, hip frame 22, leg frame 23 and foot frame 24, i.e. the outer side of the side panel 25. The surrounding panel 7 is also located on the outer side of the fixed base 1, and the surrounding panel 7 can serve as a shield.

[0025] In actual use, when lying flat, the back support 21, leg support 23, and foot support 24 are all horizontal and supported on the sliding frame 3 for the user to use while lying flat.

[0026] When the backrest lifting actuator 4 extends, it drives the backrest frame 21 to rotate upward on the side corresponding to the head of the bed, and the rearward pull rod 5 to rotate upward at the same time on the end corresponding to the foot of the bed. At the same time, it pulls the sliding frame 3 towards the head of the bed, reducing the distance between the backrest frame 21 and the headboard mounted on the fixed base 1, thus preventing pillows or other objects located at the head of the bed from falling between the headboard and the backrest frame 21. When the backrest lifting actuator 4 retracts, the backrest frame 21 rotates downward, and the rearward pull rod 5 also rotates downward, pushing the sliding frame 3 towards the foot of the bed.

[0027] When the leg lift actuator 6 extends, it drives the leg frame 23 to rotate upward toward the foot of the bed, and at the same time, the foot frame 24 is lifted upward toward the head of the bed. Due to the support of the support rod 9, the foot frame 24 on the side corresponding to the foot of the bed will also lift upward synchronously to support the user's legs and feet. When the leg lift actuator 6 retracts, the leg frame 23 and foot frame 24 return to their original positions.

[0028] With the fixed base 1, the bed can be placed directly on the ground for use, making it convenient to use.
