[0025] This embodiment provides an anti-pinch slidable device, which includes a bed base frame 3, a connecting frame 2 and a back panel frame 1.

[0026] The bed frame 3 includes two parallel side beams and two parallel cross beams. The two side beams and the two cross beams cooperate and connect to form a square frame structure. The two cross beams are respectively the head side cross beam and the hip side cross beam. A middle beam is provided between the two cross beams, and the ends of the middle beam are connected to the two side beams. The bed frame 3 is provided with two parallel bottom frame connecting pieces 8. The bottom frame connecting pieces 8 are arranged between the middle beam and the head side cross beam and are parallel to the side beams. The ends of the bottom frame connecting pieces 8 are respectively connected to the middle beam and the head side cross beam.

[0027] The hip side of the back panel frame 1 is connected to the bed frame 3 via a bearing assembly. There are two bearing assemblies, which are symmetrically arranged on both sides of the back panel frame 1. The bearing assembly includes a bearing 6, a bearing rail 10, and a bearing fixing pin 7. The bearing rail 10 is fixedly installed on the bed frame 3. The bearing rail 10 is arranged between the hip side cross beam and the middle beam and is parallel to the side beam. The two ends of the bearing rail 10 are respectively connected to the hip side cross beam and the middle beam. The outer ring of the bearing 6 is rollingly installed in the bearing rail 10. One end of the bearing fixing pin 7 is connected to the inner ring of the bearing 6. A bearing fixing plate 5 is connected to the back panel frame 1. The bearing fixing plate 5 has a fixing pin through hole for the bearing fixing pin 7 to pass through. The other end of the bearing fixing pin 7 is fixedly installed in the fixing pin through hole.

[0028] The connecting frame 2 comprises two parallel connecting rods, with a crossbar positioned between them. The ends of the crossbar are connected to the connecting rods on the same side. One side of the connecting frame 2 is pivotally connected to the bed frame 3 via a first pin, and the other side is pivotally connected to the back of the back panel frame 1 via a second pin.

[0029] There are two first pins, which are symmetrically arranged on the two connecting rods on both sides of the connecting frame 2. The two connecting rods of the connecting frame 2 are arranged between the two bottom frame connecting pieces 8. The two connecting rods of the connecting frame 2 respectively cooperate with the bottom frame connecting pieces 8 on the same side to form a first pin hole for the first pin to pass through. The two first pins are respectively installed in the corresponding first pin holes.

[0030] There are two second pins, which are symmetrically arranged on the two connecting rods on both sides of the connecting frame 2. The back of the back panel frame 1 is provided with two connecting frame fixing plates 4 corresponding to the second pins. The two connecting frame fixing plates 4 are arranged between the two connecting rods of the connecting frame 2. The two connecting rods of the connecting frame 2 respectively cooperate with the connecting frame fixing plates 4 on the same side to form second pin holes for the second pins to pass through. The two second pins are respectively installed in the corresponding second pin holes.

[0031] The connecting frame 2 is driven by a driver to rotate about the central axis of the first pin, which in turn drives the back panel frame 1 to rotate about the central axis of the bearing fixing pin 7. The bearing 6 is then driven to roll along the bearing guide rail 10 via the back panel frame 1 and the bearing fixing pin 7. In this embodiment, the driver is a linear motor. A pair of driver fixing plates 9 are connected between the two base frame connecting plates 8 on the middle beam. The driver is rotatably mounted on the driver fixing plates 9 via a third pin. The telescopic end of the driver is rotatably mounted on the crossbar of the connecting frame 2.

[0032] In the device of the present invention, when the connecting frame is driven to rotate by the driving member, the back panel frame is driven to rotate around the central axis of the bearing fixing pin. At the same time, the bearing is driven to roll along the bearing slide rail through the back panel frame and the bearing fixing pin. The back panel frame is away from the user's buttocks, thereby effectively preventing the back panel frame from squeezing the buttocks when moving upward, thereby improving the user's comfort and experience.
