[0033] Based on the above structure, the headrest frame 2 in this solution is supported in the headboard frame 1 through the angle adjustment mechanism 3. By turning on the angle adjustment mechanism 3, the headrest frame 2 can be tilted at a pitch angle relative to the headboard frame 1 within a certain range, so that the headrest frame 2 can be adjusted according to the needs of the human body, making the human body more comfortable when in use.

[0034] As an example, the headboard 1 may include a first side frame plate 11, a second side frame plate 12, a central support plate 13 and a back plate 14; the first side frame plate 11 and the second side frame plate 12 are respectively vertically arranged at the two ends of the back plate 14, and the central support plate 13 is arranged at the center position of the first side frame plate 11 and the second side frame plate 12; a lifting switch 15 may also be provided on the end surfaces of the first side frame plate and the second side frame plate; the position of the lifting switch 15 is not higher than the horizontal position of the lowest point of the headrest frame 2.

[0035] Based on the above structure, the entire bedside table forms a stable frame structure through the first side frame plate 11, the second side frame plate 12, the central support plate 13 and the back plate 14. The special setting of the lifting switch 15 makes it convenient for the human body to open or close it, making it more convenient to use.

[0036] As an example, a first cavity is formed between the first side frame plate 11 and the center support plate 13, a second cavity is formed between the second side frame plate 12 and the center support plate 13, and the headrest frame 2 is embedded in the first cavity and the second cavity respectively;

[0050] The contact portion between the upper connecting plate 331 and the headrest frame 2 may be provided with a reinforcement pad 19;

[0051] Based on the above structure, the fixing plate 338 and the fixing arc plate 337 can ensure the stability of the connection through multiple fixing holes. At the same time, a reinforcing pad 19 is provided at the contact part between the upper connecting plate 331 and the headrest frame 2 to prevent loosening between the headrest frame 2 and the angle adjustment mechanism 3 during long-term use.

[0052] As an example, an L-shaped connecting plate 20 is arranged between the movable rod and the inner support rod 333; the L-shaped connecting plate 20 may include a first end plate 210 and a second end plate 211 that are perpendicular to each other, the movable rod and the first end plate 210 are fixedly connected by bolts, the second end plate 211 is connected to the inner support rod 333, and the horizontal height of the connection position of the second end plate 211 and the inner connecting rod is not lower than the horizontal height of the hinge position of the inner support plate and the third support leg 339.
