[0029] Example 1

[0030] like Figure 1 to Figure 7 As shown, the present invention provides a technical solution:

[0031] A bedside frame 1 with an adjustable backrest angle, which at least includes but is not limited to the bedside frame 1, a headrest frame 2 and an angle adjustment mechanism 3; the bedside frame 1 is provided with a first connecting portion that cooperates with the angle adjustment mechanism 3, the headrest frame 2 is provided with a second connecting portion that cooperates with the angle adjustment mechanism 3, the headrest frame 2 is embedded in the bedside frame 1 through the angle adjustment mechanism 3, and the pitch angle of the headrest frame 2 can be changed under the action of the angle adjustment mechanism 3.

[0032] Based on the above structure, the headrest frame 2 in this scheme 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 using it.

[0033] 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 arranged 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 lowest horizontal position of the headrest frame 2.

[0034] 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 is convenient for the human body to open or close, and it is more convenient to use.

[0035] As an example, a first cavity is formed between the first side frame plate 11 and the central support plate 13, a second cavity is formed between the second side frame plate 12 and the central support plate 13, and the headrest frame 2 is embedded in the first cavity and the second cavity respectively;

[0036] Based on the above structure, by arranging adjustable headrest frames 2 on both sides of the headboard 1, the headrest frame 2 on one side can be adjusted independently during use, and can be adjusted according to the different pitch requirements of the heads of different people, thereby increasing the use scenarios of this solution.

[0037] As an example, the angle adjustment mechanism 3 may include an electric telescopic rod 31, a movable rod 32 and a movable connecting frame 33; the electric telescopic rod 31 is connected to the first connecting part, the movable rod 32 is connected to the output end of the electric telescopic rod 31, and the two fixed ends of the movable connecting frame 33 are respectively arranged on the headboard frame 1 and the headrest frame 2; the movable connecting frame 33 is arranged on both sides of the headrest frame 2, and the movable rod 32 is connected to the two movable connecting frames 33.

[0038] Based on the above structure, by setting up two movable connecting frames 33, on the one hand, the angle adjustment structure can support the headrest frame 2 more stably, and at the same time, the two movable connecting frames 33 can be driven more stably and are smoother to use. At the same time, by setting up an electric telescopic rod 31, the pitch angle of the headrest frame 2 can be adjusted more accurately and easily.

[0039] As an example, the electric telescopic rod 31 may include a lifting rod 311, a power motor 312 and a motor seat 313; the lifting rod 311 is arranged on the motor seat 313, the power motor 312 is arranged on the side wall of the motor seat 313, and a first connecting pin 314 connected to the first matching portion is arranged at the bottom of the motor seat 313;

[0041] Based on the above structure, by setting the first support rod 16 and the electric telescopic rod 31 as a hinged structure, the electric telescopic rod 31 can be easily rotated during operation, so that the pitch adjustment of the headrest frame 2 can be carried out smoothly.

[0042] As an example, an arc-shaped connecting ear 321 is arranged between the movable rod 32 and the output end of the lifting rod 311, a pin hole 322 is arranged on the arc-shaped connecting ear 321, and a second connecting pin 323 matching the pin hole 322 is arranged at the end of the lifting rod 311; the second connecting pin 323 is arranged on the arc-shaped connecting ear 321 to form a hinge structure; the bending direction of the arc-shaped connecting ear 321 is downward.

[0043] Based on the above structure, by setting the arc-shaped connecting ear 321 with a predetermined angle, the force output of the electric telescopic rod 31 can be used to synchronously drive the movable connecting frame 33 to move.

[0044] As an example, the movable connecting frame 33 may include an upper connecting plate 331, a lower connecting plate 332, an inner support rod 333 and an outer support rod 334; the upper connecting plate 331 is connected to the headrest frame 2, the lower connecting plate 332 is connected to the headboard frame 1, the inner support rod 333 and the outer support rod 334 are hinged to the upper connecting plate 331 and the lower connecting plate 332 respectively; the movable rod 32 is connected to the inner support rod.

[0045] Based on the above structure, since the upper connecting plate 331 and the lower connecting plate 332 are fixedly connected to the headrest frame 2 and the bedside frame 1 respectively, and the movable rod 32 is hinged to the electric telescopic rod 31, the inner support rod 333 and the outer support rod 334 are hinged to the upper connecting plate 331 and the lower connecting plate 332 respectively, a rotatable connecting rod mechanism is formed. When the lifting rod 311 is extended, the connecting rod mechanism is similar to a vertical state. When the lifting rod 311 is contracted, the connecting rod mechanism tilts forward, so that the pitch angle of the entire headrest frame 2 can be adjusted.

[0046] As an example, the upper connecting plate 331 may include a first support leg 335, a second support leg 336 and a fixed arc plate 337, wherein the first support leg 335 and the second support leg 336 are respectively arranged on the fixed arc plate 337 at a predetermined angle, and a plurality of fixing holes are arranged on the fixed arc plate 337, and the fixed arc plate 337 is locked on the headrest frame 2 through bolts and the fixing holes; one end of the inner support rod 333 and the outer support rod 334 are respectively hinged to the ends of the first support leg 335 and the second support leg 336;

[0047] The lower connecting plate 332 may include a fixing plate 338, a third leg 339 and a fourth leg 3310; the third leg 339 and the fourth leg 3310 are respectively arranged on the fixing plate 338 at a predetermined angle, and a plurality of fixing holes are arranged on the fixing plate 338, and the fixing plate 338 is locked on the bedside frame 1 through bolts and the fixing holes.

[0048] One end of the inner support rod 333 and the outer support rod 334 are hinged to the end of the third support leg 339 and the fourth support leg 3310 respectively;

[0049] The contact portion between the upper connecting plate 331 and the headrest frame 2 may be provided with a reinforcing pad 19;

[0050] 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.

[0051] 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 between the second end plate 211 and the inner connecting rod is not lower than the horizontal height of the hinge position between the inner support plate and the third support leg 339.

[0052] Based on the above structure, the movable rod and the inner support rod 333 can be quickly assembled by specially setting the L-shaped connecting plate 20, reducing the difficulty of later disassembly and assembly. At the same time, the connecting position of the L-shaped connecting plate 20 is specially set so that when the movable rod is pushed, it can smoothly drive the headrest frame 2 to move.
