[0032] like Figure 1 and Figure 3 As shown, the support chair of this embodiment includes: a base 10, a first support structure 20, a second support structure 30, a first drive structure 40, a second drive structure 50, and a controller 60. The first support structure 20 is hinged to the base 10, and the second support structure 30 is hinged to the first support structure 20. The first drive structure 40 is disposed on the base 10 and drives the first support structure 20, and the second drive structure 50 is disposed on the first support structure 20 and drives the second support structure 30. The controller 60 is connected to both the first drive structure 40 and the second drive structure 50.

[0033] Applying the technical solution of this embodiment, the support chair includes a base 10, a first support structure 20 hinged to the base 10, a second support structure 30 hinged to the first support structure 20, a first drive structure 40 disposed on the base 10, a second drive structure 50 disposed on the first support structure 20, and a controller 60. The first drive structure 40 drives the first support structure 20, and the second drive structure 50 drives the second support structure 30. Through the above arrangement, the first drive structure 40 can drive the first support structure 20 to rotate relative to the base 10, and the second drive structure 50 can drive the second support structure 30 to rotate relative to the first support structure 20. This allows the first support structure 20 and the second support structure 30 to move to different positions, thereby enabling the first support structure 20 and the second support structure 30 to support the human body in different postures, thus making the position adjustment posture of the support chair more versatile. Therefore, the technical solution of this embodiment effectively solves the problem of limited posture adjustment in related technologies.

[0034] The base 10 includes a connecting frame 11, a first support structure 20 is hinged to the connecting frame 11, and a first drive structure 40 is disposed on the connecting frame 11.

[0035] Specifically, the first end of the first drive structure 40 is hinged to the connecting frame 11, and the second end of the first drive structure 40 is hinged to the first support structure 20.

[0036] The connecting frame 11 includes a first sub-frame and a second sub-frame. The second sub-frame extends along the height direction of the supporting chair, while the first sub-frame lies in a horizontal plane. The second sub-frame comprises two spaced-apart frames.

[0037] The first side and the second side of the connecting frame 11 are the two sides of the width direction of the connecting frame 11, respectively.

[0038] The width direction of the connecting frame 11 is set parallel to the width direction of the supporting chair.

[0039] The second support structure 30 includes a first support frame 31 and a first support pad 32 disposed on the first support frame 31.

[0040] like Figures 1 to 5 As shown, in this embodiment, the support chair further includes a third support structure 70 and a third drive structure 80. The third support structure 70 is located on the side of the first support structure 20 away from the second support structure 30, and is hinged to the first support structure 20. The third drive structure 80 is disposed on the first support structure 20 and drives the third support structure 70. The first support structure 20 supports the buttocks, the second support structure 30 supports the back, and the third support structure 70 supports the legs. The multiple support structures have a first support state and a second support state. When the support chair is in the first support state, there is a first preset angle between the first support structure 20 and the third support structure 70, and a second preset angle between the second support structure 30 and the first support structure 20. When the support chair is in the second support state, the third support structure 70 is higher than the second support structure 30. The third drive structure 80 can drive the third support structure 70 to rotate relative to the first support structure 20, thereby enabling the first support structure 20, the second support structure 30, and the third support structure 70 to support the human body in different postures. The first support structure 20, the second support structure 30, and the third support structure 70 can support different parts of the human body, making the body more comfortable. When the support chair is in the first support state, it is convenient for the human body to sit in the support chair. When the support chair is in the second support state, the human body's legs are higher than the human body's head, thus improving blood supply to the upper limbs.

[0041] When the support chair is in the first support state, the first support structure 20 is flat with the ground, the first preset angle is an obtuse angle, and the second preset angle is an obtuse angle.

[0042] The support chair also includes a third support state. When the support chair is in the third support state, the first support structure 20, the second support structure 30 and the third support structure 70 are set flush with each other and are all parallel to the ground.

[0043] When the support chair is in the second support state, the human body is in the Teschneider position.

[0044] like Figure 1 As shown, in this embodiment, the support chair also includes a restraint strap 90. Both ends of the restraint strap 90 are detachably connected to both sides of the second support structure 30 in the width direction. When the support chair is in the second support state, the restraint strap 90 is connected to the second support structure 30. By setting the restraint strap 90, the human body can be restrained, preventing the human body from falling off the support chair when it is in the second support state.

[0045] The constraint band 90 is detachably connected to the second support structure 30.

[0046] like Figure 1 and Figure 3 As shown, in this embodiment, the third support structure 70 includes a first sub-support structure 71 for supporting the thigh and a second sub-support structure 72 for supporting the calf. A first side of the first sub-support structure 71 is hinged to the second sub-support structure 72, and a second side of the first sub-support structure 71 is hinged to the first side of the first support structure 20. The third drive structure 80 drives the first sub-support structure 71. The support chair also includes a transmission member 100, whose first end is hinged to the first support structure 20, and whose second end is hinged to the second sub-support structure 72. The first sub-support structure 71 supports the thigh, and the second sub-support structure 72 supports the calf, thus enabling the support chair to effectively support various parts of the human body. The third drive structure 80 can drive the first sub-support structure 71 to rotate relative to the first support structure 20. Under the action of the transmission component 100, the second sub-support structure 72 can rotate relative to the first sub-support structure 71. This allows for adjustment of the relative position of the first sub-support structure 71 and the first support structure 20, as well as the relative position of the first sub-support structure 71 and the second sub-support structure 72, thereby adjusting the posture of the support chair and making the human body more comfortable.

[0047] The first sub-support structure 71 includes a second support frame 711 and a second support pad 712 disposed on the second support frame 711.

[0048] The second sub-support structure 72 includes a third support frame 721 and a third support pad 722 disposed on the third support frame 721.

[0049] The transmission component 100 includes a transmission rod.

[0050] like Figure 1 and Figure 3 As shown, in this embodiment, the support chair also includes a fourth drive structure 110 and a collection cylinder 120. The collection cylinder 120 is rotatably mounted on the third support structure 70. The fourth drive structure 110 drives the collection cylinder 120 to collect the bed sheet. The fourth drive structure 110 can drive the collection cylinder 120 to rotate, thereby enabling the collection cylinder 120 to collect the bed sheet, that is, to collect the used bed sheet.

[0051] The third support structure 70 includes a first support shaft, and the collection cylinder 120 is rotatably mounted on the first support shaft.

[0052] like Figure 1 and Figure 8 As shown, in this embodiment, the support chair also includes a mounting shaft 130 for mounting the sheet roll 1. The mounting shaft 130 is disposed on the second support structure 30. By providing the mounting shaft 130, the installation of the sheet roll 1 is facilitated, making the replacement of the sheet more convenient.

[0053] The support chair also includes an anti-slip part, which is disposed on the second support structure 30 corresponding to the mounting shaft 130. The sheet roll 1 is clamped between the mounting shaft 130 and the anti-slip part.

[0054] The anti-slip unit includes a first stop and a second stop. The first stop is adjustable in position, and the second stop has a stopping position and a disengaged position. When the second stop is in the stopping position, it stops the first stop; when it is in the disengaged position, it avoids the first stop. By setting the second and first stops, when the second stop switches from the locked position to the disengaged position, the first stop can move, thereby moving to a position that avoids the sheet roll 1. This allows the sheet roll 1 to be removed after a certain period of use.

[0055] like Figure 1 and Figure 10As shown, in this embodiment, the support chair also includes a limiting member 140 and a locking member 150 corresponding to the limiting member 140. The limiting member 140 is positionally adjustable, and the locking member 150 has a locking position and a clearance position. When the locking member 150 is in the locking position, it stops the limiting member 140; when the locking member 150 is in the clearance position, it clearances the limiting member 140. The limiting member 140 is correspondingly positioned to the collection cylinder 120. Both the limiting member 140 and the collection cylinder 120 are mounted on the second support structure 30, or both are mounted on the third support structure 70. By setting the locking member 150 and the limiting member 140, when the locking member 150 switches from the locking position to the clearance position, the limiting member 140 can move, thereby moving to a position that clearances the collection cylinder 120. This allows the collection cylinder 120 to be removed after a certain period of use.

[0056] It should be noted that the first stop and the limiting member 140 have the same structure. The second stop and the locking member 150 have the same structure.

[0057] In other embodiments, the collection cylinder 120 is rotatably disposed on the second support structure 30, and the limiting member 140 is disposed on the second support structure 30 corresponding to the collection cylinder 120.

[0058] like Figure 1 As shown, in this embodiment, the limiting member 140 includes a limiting plate 141, which is rotatably disposed. The rotation axis of the limiting plate 141 has a preset angle with the axis of the collecting cylinder 120. The limiting plate 141 can rotate, so that after the locking member 150 switches from the locked position to the avoidance position, the limiting plate 141 can rotate to avoid the collecting cylinder 120, which facilitates the removal of the collecting cylinder 120.

[0059] The limiting member 140 also includes a second support shaft, which is disposed on the limiting plate 141. When the locking member 150 is in the locked position, the second support shaft is inserted into the second end of the collecting cylinder 120, facilitating the rotation of the collecting cylinder 120. The first end of the collecting cylinder 120 is rotatably disposed on the first support shaft.

[0060] The locking element includes a first locking plate, which is rotatably disposed. When the locking element 150 is in the locked position, the limiting plate 141 is located between the first locking plate and the collecting cylinder 120, and the first locking plate stops the limiting plate 141. When the first locking plate is in the avoidance position, the locking element 150 avoids the limiting plate 141.

[0061] The locking element also includes an operating handle, which is disposed on the first locking plate. A mounting groove is provided on the limiting plate 141. When the locking element 150 is in the locked position, a portion of the operating handle is inserted into the mounting groove; when the first locking plate is in the clearance position, the operating handle separates from the mounting groove.

[0062] The locking component also includes a second locking plate, which is rotatably disposed. The second locking plate is spaced apart from the first locking plate, and the operating plate is connected to both the first and second locking plates. When the locking component 150 is in the locked position, the limiting plate 141 is located between the first and second locking plates. When the first locking plate is in the avoidance position, both the first and second locking plates avoid the limiting plate 141.

[0063] like Figure 1 and Figure 6 As shown, in this embodiment, the first support structure 20 includes a mounting frame 21 and a connecting frame 22. The mounting frame 21 is hinged to the base 10.

The first end of the second drive structure 50 is hinged to the connecting frame 22, and the second end of the second drive structure 50 is hinged to the second support structure 30. The first drive structure 40 can drive the mounting frame 21 to rotate relative to the base 10, thereby enabling the mounting frame 21 to drive the connecting frame 22 to move relative to the base, and further enabling the mounting frame 21 to drive the second drive structure 50 to move, thus facilitating the second drive structure 50 to drive the second support structure 30.

[0064] The connecting frame 22 includes a first connecting plate, a second connecting plate, and a reinforcing plate connecting the first connecting plate and the second connecting plate. Both the first connecting plate and the second connecting plate are connected to the mounting frame.

[0110] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0111] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0112] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0113] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
