[0035] The contents of this application will be further described below with reference to embodiments and accompanying drawings. It should be noted that the following description is merely illustrative and not a specific limitation of this application.

[0036] Please refer to the following: Figures 1 to 4 , Figure 1 This is a three-dimensional structural diagram of the assisted sitting seat disclosed in this application when the seat cushion is not raised. Figure 2 yes Figure 1 A side view of the seat cushion and base plate in the indicated state. Figure 3 This is a three-dimensional structural diagram of the assisted sitting seat disclosed in this application after the seat cushion is raised. Figure 4 yes Figure 3 The diagram shows the side view of the seat cushion and base plate in the indicated state. This application discloses an assisted standing chair, capable of... Figure 1 Switching to Figure 3 This state is designed to assist users in getting up.

[0037] Please combine Figures 1 to 4 This application provides an assistive sitting chair 1, including a support 10, a seat cushion 20, a lifting mechanism 30, and a cane 40. The support 10 includes a base plate 101 and an armrest 102. The seat cushion 20 has a first end 201 and a second end 202 opposite to each other. The first end 201 is rotatably connected to the base plate 101. The lifting mechanism 30 is connected to the second end 202 and is located between the base plate 101 and the seat cushion 20. The lifting mechanism 30 is used to drive the second end 202 to move away from or towards the base plate 101 to adjust the tilt angle of the seat cushion 20 relative to the base plate 101. The cane 40 is detachably connected to the armrest 102.

[0038] The assisted standing chair 1 provided in this application embodiment has a first end 201 of the seat cushion 20 rotatably connected to the base plate 101. The lifting mechanism 30 is used to drive the second end 202 of the seat cushion 20 to move away from or towards the base plate 101 to adjust the tilt angle of the seat cushion 20 relative to the base plate 101. This allows the second end 202 of the seat cushion 20 to move away from the base plate 101 when an elderly person (or other users who have difficulty standing, such as pregnant women) stands up, thereby increasing the tilt angle of the seat cushion 20 relative to the base plate 101 and helping the elderly person to stand up. This improves the ease of use of the assisted standing chair 1. At the same time, a cane 40 is detachably connected to the armrest 102 to provide support when the elderly person stands up and walks, further assisting them in standing up and providing support when walking, thus achieving the function of assisting walking.

[0039] Optionally, the tilt angle of the seat cushion 20 relative to the base plate 101 can be 0°-13°, such as 1°, 3°, 5°, 8°, 10°, 12° or 13°, so that it can provide better support for the user when the seat cushion 20 is not raised relative to the base plate 101, thereby improving the user's experience, and also provide a larger range of motion for the seat cushion 20 to help the user get up.

[0040] Please combine Figure 2 , Figure 4 as well as Figure 6In some embodiments, the lifting mechanism 30 includes a control component 301, a first support component 302, and a second support component 303. The first support component 302 includes a first support rod 3021, a first slide rail 3022, and a first slider 3023. The second support component 303 includes a second support rod 3031. One end of the first support rod 3021 is rotatably connected to the first slider 3023, and the first slider 3023 is slidably connected to the first slide rail 3022. The first slide rail 3022 is connected to the base plate 101. The other end of the first support rod 3021 is rotatably connected to the second end 202. The second support rod 3031 is rotatably connected to the first support rod 3021 and is arranged to cross the first support rod 3021. One end of the second support rod 3031 is movably connected to the base plate 101, and the other end of the second support rod 3031 is movably connected to the first end 201. The control component 301 is used to drive the first slider 3023 to move along the first slide rail 3022.

[0041] In this way, the first support rod 3021 and the second support rod 3031 are arranged in a cross structure. The first support rod 3021 and the second support rod 3031 are respectively connected to the second end 202 and the first end 201 of the seat cushion 20. This can increase the support points of the lifting mechanism 30 on the seat cushion 20, thereby improving the stability of the seat cushion 20. It also helps to distribute the force at the rotational connection between the first end 201 of the seat cushion 20 and the base plate 101, thereby improving the structural stability of the assisted standing seat 1.

[0042] Optionally, the second support assembly 303 further includes a second slide rail 3032 and a second slider 3033. The second slide rail 3032 is fixedly connected to the first end 201 of the seat cushion 20, and the second slider 3033 is slidably connected to the second slide rail 3032. One end of the second support rod 3031 is rotatably connected to the second slider 3033, and the other end of the second support rod 3031 is rotatably connected to the base plate 101.

[0043] In this way, the second support rod 3031 is connected to the seat cushion 20 via the second slide rail 3032, which helps to increase the connection area between the lifting mechanism 30 and the seat cushion 20, thereby improving the stability of the seat cushion 20 and thus improving the structural stability of the assisted sitting seat 1. Furthermore, since the distance between the second end 202 of the seat cushion 20 and the base plate 101 changes, the distance and tilt angle of the position of the seat cushion 20 near the first end 201 relative to the base plate 101 also change accordingly. By setting the second slide rail 3032 and the second slider 3033, it is possible to ensure that the second support rod 3031 and the second slider 3033 are connected to the seat cushion 20. The reliable connection of the seat cushion 20 meets the greater height adjustment requirements of the second end 202. When the height of the first end 201 relative to the base plate 101 changes, the connection between the seat cushion 20 and the second support rod 3031 is maintained by the relative movement of the second slider 3033 and the second slide rail 3032. This ensures the support effect of the second support component 303 on the seat cushion 20 while increasing the adjustable height of the second end 202 relative to the base plate 101. This helps to increase the tilt angle range of the seat cushion 20 relative to the base plate 101 and improve the effect of the assisted standing seat 1 on assisting the user to stand up.

[0044] Understandably, in some other embodiments, the second support rod 3031 is rotatably connected to the first end 201 of the seat cushion 20.

[0045] In some embodiments, there are at least two first support components 302, one of which is located on one side of the seat cushion 20 and the other is located on the other side of the seat cushion 20. There are at least two second support components 303, which correspond one-to-one with the first support components 302. This increases the number of support points of the lifting mechanism 30 on the seat cushion 20, thereby improving the stability of the seat cushion 20 and the structural stability of the assisted standing seat 1.

[0046] Optionally, the lifting mechanism 30 further includes a first connecting rod 304, through which the first sliders 3023 of at least two first support components 302 are connected, and the control component 301 is used to drive the first connecting rod 304 to move. This enables at least two first support components 302 to move simultaneously, thereby improving the movement reliability of the lifting mechanism 30 and making the structure of the assisted standing seat 1 more stable and reliable.

[0047] Optionally, there are two first support components 302 and two second support components 303. The lifting mechanism 30 also includes multiple second connecting rods 305. One second connecting rod 305 is connected to the end of the two first support rods 3021 away from the first slider 3023. Another second connecting rod 305 is connected to the two second sliders 3033. Yet another second connecting rod 305 is connected to the end of the two second support rods 3031 away from the second sliders 3033. This improves the overall integrity of the lifting mechanism 30, allowing the two first support components 302 and the two second support components 303 to move simultaneously. This enhances the reliability of the lifting mechanism 30's movement, making the structure of the assisted standing seat 1 more stable and reliable.

[0048] In some embodiments, the control component 301 includes a drive member 3011, a first positioning member 3012, a second positioning member 3013, a rotating screw 3014, and a moving member 3015. The first positioning member 3012 and the second positioning member 3013 are mounted on the base plate 101. One end of the rotating screw 3014 is rotatably connected to the first positioning member 3012, and the other end of the rotating screw 3014 is rotatably connected to the second positioning member 3013. The output end of the drive member 3011 is connected to the rotating screw 3014. The moving member 3015 is provided with a threaded hole, through which the rotating screw 3014 passes and is threadedly connected. The moving member 3015 is located between the first positioning member 3012 and the second positioning member 3013. The moving member 3015 is connected to the first connecting rod 304 so as to simultaneously drive the two first sliders 3023 to move under the control of the drive member 3011.

[0049] In this way, using a ball screw to drive the first slider 3023 can improve the smoothness of the movement of the lifting mechanism 30. At the same time, by limiting the movement of the moving part 3015 through the first positioning member 3012 and the second positioning member 3013, the movement distance of the first slider 3023 can be limited, preventing the first slider 3023 from dislodging from the first slide rail 3022. Furthermore, by controlling the distance between the first positioning member 3012 and the second positioning member 3013 and the length of the rotating screw 3014, the movement distance of the second end 202 of the seat cushion 20 relative to the base plate 101 can be controlled, thereby controlling the strength of the assistive seat 1 in helping the user get up.

[0050] Optionally, the drive element 3011 can be a motor, which drives the rotating screw to rotate.

[0051] Understandably, in other embodiments, the drive element 3011 may also be a cylinder or piston, which drives the first slider 3023 to move along the first slide rail 3022 through the reciprocating motion of the cylinder or piston.

[0052] Please refer to it again. Figure 1In some embodiments, the control component 301 includes a push button switch 3016, which is mounted on the bracket 10 and electrically connected to the drive component 3011. The drive component 3011 is used to drive the rotating screw 3014 to move under the control of the push button switch 3016, so that the moving component 3015 and the first connecting rod 304 drive the first slider 3023 to move on the first slide rail 3022.

[0053] In this way, by controlling the start and stop of the drive unit 3011 through the button switch 3016, the use of the assisted standing seat 1 becomes simpler and more convenient. It is also beneficial for users to flexibly control the tilt angle of the seat cushion 20 relative to the base plate 101, which is especially practical for the elderly who have difficulty learning to operate it.

[0054] Optionally, the bracket 10 includes two side panels 103, with the seat cushion 20 located between the two side panels 103. The two side panels 103 are respectively connected to the base plate 101. The bracket 10 also includes a front support leg 104, which is connected to the base plate 101 and the side panels 103. A push-button switch 3016 is located on the top of the front support leg 104, and the height of the front support leg 104 is less than the height of the cane 40. When the cane 40 is connected to the armrest 102, the front support leg 104 is located between the side panels 103 and the cane 40. In other words, the push-button switch 3016 is located in the space between the side panels 103 and the cane 40, which helps to prevent accidental activation and improves the reliability of the assisted standing seat 1. Furthermore, the side panels 103 can also limit the position of the seat cushion 20, improving the structural reliability of the assisted standing seat 1.

[0055] Understandably, in some other embodiments, the push-button switch 3016 may also be located on the side panel 103 or the armrest 102.

[0056] Please combine Figure 1 , Figure 5 and Figure 7 Optionally, the front support leg 104 is provided with a first magnetic attraction member 1041, and the cane 40 is provided with a second magnetic attraction member, the magnetic poles of the second magnetic attraction member being opposite to those of the first magnetic attraction member 1041. This allows the cane 40 to be magnetically connected to the front support leg 104, which facilitates the positioning of the cane 40, and makes it easier to assemble and disassemble the cane 40 and the armrest 102, thus improving the ease of use of the cane 40.

[0057] In some embodiments, the assisted standing seat 1 further includes a rotating connector 50, which is mounted on the armrest 102. The cane 40 and the rotating connector 50 can rotate relative to each other so that the cane 40 and the rotating connector 50 can be detachably connected.

[0058] In this way, the connection between the cane 40 and the armrest 102 is achieved by rotating the connector 50, so that the cane 40 can be installed and removed by rotating, which can facilitate the installation and removal of the cane 40 and improve the convenience of use.

[0059] Understandably, in other embodiments, the cane 40 and the armrest 102 may also be connected by magnetic adsorption, snap-fit, or binding.

[0060] Optionally, the rotating connector 50 is provided with a mounting cavity. One end of the rotating connector 50 is rotatably connected to the handrail 102, and the other end of the rotating connector 50 is provided with a mounting hole 501. The mounting hole 501 communicates with the mounting cavity. The mounting hole 501 has different diameters along two staggered directions. The cane 40 is provided with a latching part 401 whose shape matches the mounting hole 501. The latching part 401 is used to extend into the mounting cavity through the mounting hole 501. The rotating connector 50 is used to rotate relative to the latching part 401 so that the mounting hole 501 corresponds to the latching part 401 so that the latching part 401 can be withdrawn from the mounting hole 501. Alternatively, the mounting hole 501 and the latching part 401 are staggered so that the rotating connector 50 engages with the latching part 401.

[0061] In this way, by rotating the rotating connector 50, the position of the latching part 401 relative to the mounting hole 501 changes, thereby enabling the installation and removal of the cane 40 from the handrail 102. This improves the efficiency of the cane 40's installation and removal, and enhances its ease of use. When the rotating connector 50 rotates to the point where the mounting hole 501 aligns with the latching part 401, the latching part 401 can extend into or retract from the mounting hole 501, connecting or separating the cane 40 from the rotating connector 50. At this point, the cane 40 can be removed from the handrail 102 to provide auxiliary support for the user's walking. After use, the latching part 401 of the cane 40 can be inserted into the mounting hole 501 for fixation. When the rotating connector 50 rotates to the point where the mounting hole 501 and the latching part 401 intersect, the latching part 401 located in the mounting cavity abuts against the inner wall of the mounting cavity, causing the latching part 401 to engage with the rotating connector 50, thus fixing the cane 40 to the handrail 102. In addition, the cane 40 and armrest 102 can be detached and reattached by rotating the rotating connector 50, which is more convenient than rotating the cane 40. It does not require leaving space for the cane 40 to rotate, thus avoiding the cane 40 hitting people or objects around the assisted standing seat 1 when rotating, thereby improving the safety of using the assisted standing seat 1.

[0062] Optionally, the shape of the mounting hole 501 can be elliptical, rectangular, triangular, or irregular. The specific shape can be set according to actual needs and there is no restriction here. As long as the buckle part 401 can switch from a movable state relative to the mounting hole 501 to a state that cannot be withdrawn from the mounting hole 501 after the rotating connector 50 is rotated, it is acceptable.

[0063] Understandably, in other embodiments, the rotating connector 50 and the cane 40 may also be connected by a threaded connection, or the rotating connector 50 may be connected to the cane 40 by a rotating buckle.

[0064] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
