[0024] Example

[0025] Reference Figure 1 and Figure 2 The utility model provides a bedside structure with an adjustable pillow, comprising: a bedside frame 10, a pillow frame 20 and a movable connecting rod assembly;

[0026] The pillow frame 20 is provided with a pillow pad 21; the movable connecting rod assembly includes a first fixed arm 30 fixed to the bedside frame 10, a second fixed arm 60 fixed to the pillow frame 20, a first movable arm 40, a second movable arm 50 and a limiting frame 70; the two ends of the first movable arm 40 are respectively hinged to the upper ends of the first fixed arm 30 and the second fixed arm 60; the second movable arm 50 is respectively hinged to the lower ends of the first fixed arm 30 and the second fixed arm 60; the first fixed arm 30, the first movable arm 40, the second movable arm 50 and the second fixed arm 60 form a four-bar movable mechanism, which can make the pillow frame 20 vertically against the bedside frame 10 or extend obliquely toward the front of the bedside frame 10; the limiting frame 70 can abut against the first movable arm 40 or the second movable arm 50 to limit the position of the pillow frame 20 extending out of the bedside frame 10.

[0027] In the utility model, the first fixed arm 30, the first movable arm 40, the second movable arm 50 and the second fixed arm 60 form a four-bar movable mechanism, which can make the pillow frame 20 vertically against the bedside frame 10 or tilted and extended toward the front of the bedside frame 10, and the limiting frame 70 is used to limit the first movable arm 40 or the second movable arm 50, so as to limit the movable position of the four-bar movable mechanism; the utility model uses the four-bar movable mechanism to conveniently and simply switch the pillow frame 20 relative to the bedside frame 10 between a vertical state and a tilted and extended state, and has a strong pillow supporting strength, a simple production process, easy production and assembly, and low production cost.

[0028] In this embodiment, the limiting frame 70 is provided with a support shaft 71; the lower side of the first movable arm 40 is provided with a first limiting ear 41; when the pillow frame 20 moves to a tilted and extended state toward the front of the bedside frame 10, the first limiting ear 41 can abut against the support shaft 71. The support shaft 71 is output along the lateral direction of the limiting frame 70 and can abut against the first movable arm 40 or the second movable arm 50 to achieve the effect of supporting and limiting. For example, by abutting against the first limiting ear 41, the position of the first movable arm 40 turning downward is limited, thereby limiting the pillow frame 20 from moving to a tilted and extended state toward the front of the bedside frame 10.

[0029] Furthermore, a second limiting ear 51 is disposed on the upper side of the second movable arm 50; when the pillow frame 20 moves to a state of vertically abutting against the bedside frame 10, the second limiting ear 51 can abut against the support shaft 71. By abutting against the second limiting ear 51, the second movable arm 50 is limited to flip upward, thereby limiting the pillow frame 20 from moving to a state of vertically abutting against the bedside frame 10.

[0030] In this embodiment, in order to ensure that the relative position of the limit frame 70 and the four-bar mechanism meets the design requirements, the limit frame 70 is directly fixed to the first fixed arm 30 by bolts or screws. Of course, in other embodiments, the limit frame 70 can also be directly fixed to the second fixed arm 60.

[0031] In some embodiments, in order to improve the strength performance of the fixing arms, the first fixing arm 30 and the second fixing arm 60 are formed with a reinforcing rib structure by press forming.

[0032] In some embodiments, the independent pillow pad 21 is embedded in the pillow frame 20 to form a soft cushion structure.

[0033] In this embodiment, the pillow pad 21 is wrapped around the outer side of the pillow frame 20 to form a cushion structure that can be recessed toward the inner cavity of the pillow frame 20 .

[0034] Specifically, two pillow frames 20 are arranged at intervals along the width direction of the bedside frame 10 and connected by a crossbeam; the middle of the two pillow frames 20 is a cavity structure; the pillow pad 21 can be deformed by being recessed into the cavity. An elastic connecting belt 22 is arranged between the two pillow frames 20; a plurality of elastic connecting belts 22 are arranged at intervals along the vertical direction. The elastic connecting belt 22 can provide an elastic support effect and improve the comfort of the user's leaning.

[0035] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
