The support pad 21 is placed on the upper surface of the lifting plate 2. The support pad 21 is made of latex and has a moderate softness and firmness, which can provide good support while enhancing comfort.
[0029] Reference Figure 1 and Figure 2 A set of rotating shafts 4 are symmetrically rotatably arranged on the lower surface of the lifting plate 2. The length direction of the rotating shafts 4 is along the width direction of the lifting plate 2. A set of support rods 41 are symmetrically fixed on the rotating shafts 4 and welded to the rotating shafts 4. A connecting rod 42 is rotatably arranged between the support rods 41 and at the bottom end. The length direction of the connecting rod 42 is parallel to the length direction of the rotating shaft 4. A slider 43 is integrally arranged on the connecting rod 42. The slider 43 is slidably arranged on the upper surface of the base plate 1 by a guide rail. A sliding assembly 5 is provided on the base plate 1. When using the lumbar support pad for lumbar or neck support, the base plate 1 is placed flat on the bed, and the support rods 41 support the lifting plate 2. The sliding assembly 5 drives the sliders 43 to slide towards or away from each other, causing the connecting rods 42 to rotate between the support rods 41. At the same time, the support rods 41 rotate with respect to the rotating shafts 4, changing the tilt angle of the support rods 41, thereby changing the distance between the lifting plate 2 and the base plate 1, and adjusting the height of the support pad 21.
[0030] Reference Figure 1 and Figure 2The sliding assembly 5 includes a power supply 51, a motor 52, a lead screw 53, a first threaded section 531, a second threaded section 532, a data cable 54, and a switch 55. The power supply 51 and the motor 52 are fixedly mounted on the upper surface of the base plate 1 by bolts. The power supply 51 is wired to the motor 52 to supply power. The drive shaft of the motor 52 is connected to the lead screw 53, and the length direction of the lead screw 53 is along the length direction of the base plate 1. The first threaded section 531 and the second threaded section 532 are symmetrically arranged on the lead screw 53 and their screwing directions are opposite. One slider 43 is threadedly connected to the first threaded section 531, and the other slider 43 is threadedly connected to the second threaded section 532. One end of the data cable 54 is electrically connected to the motor 52, and the other end of the data cable 54 passes through the elastic cloth 3 and is connected to the switch 55. When the height of the support pad 21 needs to be changed, the motor 52 is controlled by the switch 55, and the power supply 51 supplies power to the motor 52. The drive shaft of the motor 52 is controlled to rotate forward and backward by the switch 55, which drives the lead screw 53 to rotate forward and backward. After the slider 43 is guided on the base plate 1, one slider 43 slides on the first threaded section 531 and the other slider 43 slides on the second threaded section 532. The two sliders 43 slide towards each other at the same time, which in turn drives the connecting rod 42 to slide towards each other on the base plate 1. When the connecting rod 42 slides, it rotates between the support rods 41, changing the tilt direction of the support rods 41, so as to realize the rapid adjustment of the height of the lifting plate 2.
