The cushion 8 is adhered to the backrest board 7 by the Velcro 9, which is convenient for disassembly and cleaning.
[0034] Reference Figure 4 The adjustment component 6 includes a base 10 fixedly connected to the inner wall of the mounting groove 5. The setting of the base 10 facilitates the installation of the adjustment component 6 in the mounting groove 5, and a sliding groove is provided on the top outer wall of the base 10. The inner wall of the sliding groove is slidably connected to a sliding seat 12. The setting of the mounting groove 5 facilitates the installation of the base 10, and the setting of the sliding groove facilitates the sliding installation of the sliding seat 12.
[0035] Reference Figure 4 The sliding seat 12 is fixedly connected to the support rod 14, and connecting grooves are provided on the inner walls of both sides of the slide, and the inner walls of the two connecting grooves are fixedly connected with racks 11. The two racks 11 are symmetrically arranged to facilitate the limitation of the auxiliary sliding seat 12. The sliding seat 12 and the support rod 14 are connected to facilitate the support of the backrest plate 7. The setting of the mounting groove facilitates the installation of the rack 11.
[0036] Reference Figure 5 , sliding openings are provided on the outer walls of both sides of the sliding seat 12, and the inner walls of the two sliding openings are slidably connected with rack 2 15, rack 2 15 and rack 1 11 are engaged with each other, and the sliding opening on the sliding seat 12 is convenient for sliding installation of rack 2 15, and the engagement of rack 2 15 and rack 1 11 facilitates fixing the sliding seat 12 on the base 10, and the engagement of the two racks 2 15 and rack 1 11 improves the stability of the sliding seat 12 and prevents the sliding seat 12 from getting stuck in the slide groove.
[0037] Reference Figure 5The inner walls of both sides of the sliding seat 12 are fixedly connected with mounting rods 19, and the outer walls of the two mounting rods 19 are sleeved with springs 20. The two mounting rods 19 are symmetrically arranged in the sliding seat 12, and the outer walls of the two mounting rods 19 are slidably connected with sliding sleeves 18. The setting of the two springs 20 facilitates driving the two sliding sleeves 18 to always approach each other, and the outer walls of the two sliding sleeves 18 are rotatably connected to two connecting plates 17. The outer walls of the four connecting plates 17 are rotatably connected to the two racks 2 15, so that the four connecting plates 17 push the two racks 2 15 to engage with the gear 1 11, thereby facilitating the fixing of the sliding seat 12 in the slide groove. The rack 2 15 is supported by the cooperation between the sliding sleeve 18 on the mounting rod 19 and the connecting plate 17.

[0040] The implementation principle of the present application is as follows: during use, when the position of the sofa backrest needs to be adjusted, the push switch 13 is pressed. At this time, the two electromagnets 22 are turned on and off. The electromagnets 22 are energized to generate magnetism and directly attract the two armatures 16 to move toward the electromagnets 22. When the two racks 15 move toward each other, they directly push the sleeve 18 through the connecting plate 17 to compress the spring 20. At this time, the sliding seat 12 is unlocked, and the position of the backrest assembly 4 on the sofa body 1 can be directly adjusted. After the adjustment is completed, the push switch 13 is released and the two electromagnets 22 are powered off. After the electromagnet 22 is powered off, the two racks 15 are extended by the spring 20 and mesh with the rack 1 11, thereby facilitating the locking of the sliding seat 12. The backrest plate 7 and the cushion 8 are connected by Velcro 9, which is convenient for disassembly to clean the cushion 8.
