[0043] See also Figure 1 , Figure 1 The figure is a schematic structural diagram of a senior chair bracket 100 in one embodiment of the present invention. The present invention provides a senior chair bracket 100, which is disposed within the senior chair and, through its own transmission, enables functions such as leg extension, back adjustment, and seat elevation, thereby facilitating user use and improving user comfort.

[0044] The elderly chair bracket 100 includes a base 10, a drive assembly 20, a first transmission assembly 30, a leg assembly 40 and a back assembly 50. The drive assembly 20 is connected to the base 10, the first transmission assembly 30 is connected to the drive assembly 20, the leg assembly 40 and the back assembly 50 are both connected to the first transmission assembly 30, the base 10 is used to support each component, the drive assembly 20 provides driving force for the movement of the elderly chair bracket 100, the first transmission assembly 30 can drive the leg assembly 40 to extend or contract, and can drive the back assembly 50 to adjust the angle.

[0045] The first transmission assembly 30 includes a first transmission member 31, which includes a first connecting portion 311 and a second connecting portion 312. The first connecting portion 311 and the second connecting portion 312 each have a first end and a second end. The first end 313 of the first connecting portion is hinged to the leg assembly 40, and the second end 314 of the first connecting portion is fixedly connected to the second connecting portion 312 and forms an angle with the second connecting portion 312. The first end 315 of the second connecting portion is hinged to the back assembly 50, and the second end 316 of the second connecting portion is connected to the drive assembly 20.

[0046] The driving component 20 is composed of a driving member 21, the output end of the driving member 21 is connected to the second end 316 of the second connecting part, and the driving member 21 can drive the first transmission member 31 to move relative to the base 10, and make the first transmission member 31 drive the leg component 40 to extend or contract through the first end of the first connecting part, so that the first transmission member 31 drives the back component 50 to rotate relative to the base 10 through the first end 315 of the second connecting part to adjust the angle, thereby realizing the adjustment of the leg component 40 and the back component 50 through the first transmission member 31.

[0047] In the elderly chair bracket 100 provided by the present invention, the driving member 21 can move the first transmission member 31, the first connecting portion 311 of the first transmission member 31 can drive the leg assembly 40 to extend or contract, and the second connecting portion 312 of the first transmission member 31 can drive the back assembly 50 to achieve angle adjustment, so that the basic functions of the elderly chair bracket 100 can be achieved through the structure of a driving member 21 and the first transmission member 31, simplifying the structure of the elderly chair bracket 100, facilitating the production and assembly of the elderly chair bracket 100, and reducing production costs.

[0048] Please also refer to Figure 2 , Figure 2 for Figure 1 The structure diagram of the base 10 in the elderly chair bracket 100 is shown. The base 10 includes a first support rod 11, a second support rod 12, a third support rod 13 and a fourth support rod 14. The first support rod 11, the second support rod 12, the third support rod 13 and the fourth support rod 14 each have a first end and a second end arranged opposite to each other. The first end of the first support rod 11 is fixedly connected to the first end of the second support rod 12, the second end of the second support rod 12 is fixedly connected to the first end of the third support rod 13, the second end of the third support rod 13 is fixedly connected to the first end of the fourth support rod 14, and the second end of the fourth support rod 14 is fixedly connected to the first end of the first support rod 11; thus, the first support rod 11, the second support rod 12, the third support rod 13 and the fourth support rod 14 are arranged in a rectangular shape, thereby forming the basic frame of the elderly chair bracket 100.

[0049] The first support rod 11 and the third support rod 13 are both bent outward to form a reinforcement portion 15. The reinforcement portion 15 can increase the force range between the elderly chair bracket 100 and the ground. When the side force of the elderly chair bracket 100 is relatively large, the reinforcement portion 15 can effectively prevent the elderly chair bracket 100 from tipping over, thereby improving the safety of the elderly chair bracket 100.

[0050] It is worth noting that the shape of the first support rod 11, the second support rod 12, the third support rod 13 and the fourth support rod 14 is not necessarily a standard rectangle, and can be roughly rectangular. At the same time, for the convenience of subsequent description, the following text directly uses the "first end" and "second end" of each rod, and limits the specific shape of the rod to a straight line, which only indicates that the rod has a relative "first end" and "second end". In order to achieve corresponding transmission, the rod can be regular or irregular in shape.

[0051] Both ends of the fourth support rod 14, the reinforcement portion 15 of the first support rod 11 and the reinforcement portion 15 on the third support rod 13 are provided with anti-friction pads 16. The setting of the anti-friction pads 16 can prevent the elderly chair bracket 100 from sliding easily, improve the stability of the elderly chair bracket 100, and thus facilitate the safe use of the elderly chair bracket 100.

[0052] Please also refer to Figure 3 , Figure 3 for Figure 1 The schematic diagram of the structure of the driving member 21 in the elderly chair support 100 is shown. The driving assembly 20 is composed of a driving member 21, which is hinged to the second support rod 12. The output end of the driving member 21 is connected to the first transmission assembly 30 and can drive the first transmission assembly 30 to move. In this embodiment, the driving member 21 is a motor, specifically a screw motor. The screw motor has stable transmission and high output accuracy, which is suitable for the elderly chair support 100 of the present invention and can enable the elderly chair support 100 to be precisely adjusted. It is understood that in other embodiments, the driving member 21 can also be selected as other types of motors or other types of drive sources, as long as the above-mentioned driving purpose can be achieved.

[0053] Please also refer to Figure 4 、 Figure 5 and Figure 6 , Figure 4 for Figure 1 The schematic structural diagram of the first transmission assembly 30 in the elderly chair bracket 100 is shown. Figure 5 for Figure 4 The schematic structural diagram of the first transmission assembly 30 from another perspective is shown. Figure 6 for Figure 4 The diagram shows the structure of the first transmission member 31 in the first transmission assembly 30. The first transmission assembly 30 includes a first transmission member 31, a second transmission member 32, a third transmission member 33, a fourth transmission member 34, a fifth transmission member 35, and a sixth transmission member 36. The sixth transmission member 36 is hinged to the first support rod 11, and a guide groove 361 is defined on the sixth transmission member 36. A first end of the fifth transmission member 35 is hinged to the sixth transmission member 36, and the fifth transmission member 35 is provided with a guide portion 351, which is disposed in the guide groove 361. A second end of the fifth transmission member 35 is hinged to the first end of the fourth transmission member 34, and a second end of the fourth transmission member 34 is hinged to the first end of the third transmission member 33. The third transmission member 33 is hinged to the base 10, and a second end of the third transmission member 33 is hinged to the first end of the second transmission member 32. The second end of the second transmission member 32 is hinged to the first transmission member 31.

[0054] The output end of the driving member 21 is connected to the fifth transmission member 35. Under the drive of the driving member 21, when the fifth transmission member 35 rotates relative to the sixth transmission member 36, the guide part 351 slides along the guide groove 361, and the fifth transmission member 35 drives the third transmission member 33 to rotate relative to the base 10 through the fourth transmission member 34, and the third transmission member 33 drives the first transmission member 31 to move through the second transmission member 32; when the first transmission member 31 moves, it can drive the leg assembly 40 to extend or contract through the first connection part 311, and drive the back assembly 50 to rotate through the second connection part 312 to achieve angle adjustment.

[0055] In this embodiment, the fifth transmission member 35 moves from one end of the guide groove 361 close to the leg assembly 40 to the other end of the guide groove 361 away from the leg assembly 40, and the first transmission assembly 30 pushes the leg assembly 40, so that the leg assembly 40 performs an extension movement; conversely, the leg assembly 40 performs a contraction movement.

[0056] In this embodiment, the elderly chair bracket 100 also includes an intermediate plate 37, which is hinged to the guide portion 351 and the part where the fifth transmission member 35 is hinged to the sixth transmission member 36. The output end of the driving member 21 is hinged to the intermediate plate 37, and then the driving member 21 can drive the fifth transmission member 35 to rotate relative to the sixth transmission member 36 around the hinge point through the intermediate plate 37, thereby realizing the corresponding transmission relationship; it can be understood that in other embodiments, the driving member 21 can also be directly connected to the guide portion 351.

[0057] Please also refer to Figure 7 , Figure 7 for Figure 4 The diagram shows the structure of the first transmission assembly 30 and some of its components. The sixth transmission member 36 bends outward to form a lifting portion 362, which abuts the base 10. The elderly chair frame 100 also includes an adapter 17 and a support member 18. The adapter 17 abuts the lifting portion 362, and the support member 18 is fixedly connected to the adapter 17. The third transmission member 33 is hinged to the support member 18, and thus indirectly hinged to the base 10. The third transmission member 33 can rotate relative to the support member 18 about the hinge point, thereby driving the second transmission member 32 and the first transmission member 31 to rotate. The leg assembly 40 and the back assembly 50 are both hinged to the adapter 17.

[0058] In this embodiment, the support member 18 is roughly triangular in shape, with two corners of the support member 18 fixedly connected to the adapter 17, and the other corner of the support member 17 is hinged to the third rotating member 33, thereby ensuring the stability of the support member 18 relative to the adapter 17; it can be understood that in other embodiments, the support member 18 can also be set to other shapes, as long as the above-mentioned purpose can be achieved.

[0059] In this embodiment, the sixth transmission member 36 is bent outward ninety degrees to form a lifting portion 362, that is, the lifting portion 362 is perpendicular to other parts of the sixth transmission member 36; it can be understood that in other embodiments, the sixth transmission member 36 can also form the lifting portion 362 by bending at other angles.

[0060] Please also refer to Figure 8 、 Figure 9 、 Figure 10 and Figure 11 , Figure 8 for Figure 1The schematic structural diagram of the leg assembly 40 in the elderly chair bracket 100 is shown. Figure 9 for Figure 7 The schematic diagram of the structure of the leg assembly 40 in the extended state is shown. Figure 10 for Figure 1 The schematic diagram of the elderly chair support 100 in a semi-extended state is shown; Figure 11 for Figure 1 The figure shows a fully extended state of the elderly chair support 100. The leg assembly 40 includes a first leg component 41, a second leg component 42, a third leg component 43, a fourth leg component 44 and a fifth leg component 45. The first leg component 41 is hinged to the first connecting portion 311. The first end of the first leg component 41 is hinged to the back assembly 50. The second end of the first leg component 41 is hinged to the first end of the second leg component 42. The second end of the second leg component 42 is hinged to the third leg component 43. The first end of the fourth leg component 44 is hinged to the back assembly 50. The fourth leg component 44 is hinged to the second leg component 42. The fourth leg component 45 is hinged to the back assembly 50. The second end of the leg component 44 is hinged to the first end of the fifth leg component 45, and the second end of the fifth leg component 45 is hinged to the third leg component 43; driven by the first connecting part 311, the first leg component 41 can rotate relative to the back component 50 and drive the second leg component 42 to rotate, and the second leg component 42 drives the fifth leg component 45 to rotate through the fourth leg component 44, and then the second end of the second leg component 42 and the second end of the fifth leg component 45 can drive the third leg component 43 to rotate, thereby realizing the extension or contraction of the leg component 40.

[0061] The elderly chair support 100 provided by the present invention and the extension and contraction of the leg assembly 40 can enable the elderly chair support 100 to have multiple usage states, thereby improving the user's comfort and meeting the user's usage needs.

[0062] The fourth leg part 44 is also provided with a supporting portion 441. When the leg assembly 40 is retracted, the supporting portion 441 can abut against the second leg part 42, thereby creating a gap between the leg parts, preventing the leg parts from being too compact and unable to extend again, which is beneficial to the normal use of the elderly chair bracket 100.

[0063] Please also refer to Figure 12 , Figure 12 for Figure 1The back assembly 50 in the elderly chair frame is shown as a schematic diagram of the structure. The back assembly 50 includes a first back member 51, a second back member 52, a third back member 53, a fourth back member 54, a fifth back member 55, a sixth back member 56, a seventh back member 57, an eighth back member 58, a back plate 59 and an angle adjustment member 510; the first leg member 41 and the second leg member 42 are both hinged to the back plate 59; the first back member 51 is hinged to the back plate 59, the first end of the first back member 51 is hinged to the first end of the second connecting portion 312, the second end of the first back member 51 is hinged to the first end of the second back member 52, and the second end of the second back member 52 is hinged to A third back member 53, a first end of the third back member 53 is hinged to the adapter 17, a second end of the third back member 53 is hinged to the fourth back member 54, the fourth back member 54 is hinged to the back plate 59, a first end of the fifth back member 55 is hinged to the fourth back member 54, a second end of the fifth back member 55 is hinged to the sixth back member 56, a second end of the seventh back member 57 is hinged to the adapter 17, a first end of the eighth back member 58 is hinged to the sixth back member 56, a second end of the eighth back member 58 is hinged to the angle adjustment member 510, and the angle adjustment member 510 is also hinged to the back plate 59;

[0064] The second connecting portion 312 can drive the first back component 51 to rotate relative to the back plate 59, and the first back component 51 can drive the third back component 53 to rotate relative to the adapter 17 through the second back component 52. When the sixth transmission component 36 makes the back assembly 50 fully extended, under the push of the driving component 21, the sixth transmission component 36, the first back component 51 and the back plate 59 move together, the third back component 53 rotates relative to the adapter 17, the third back component 53 drives the second back component 52 to rotate relative to the back plate 59, and makes the fifth back component 55 rotate relative to the fourth back component 54, the fifth back component 55 pushes the sixth back component 56 to rotate relative to the back plate 59, the sixth back component 56 drives the seventh back component 57 to rotate relative to the adapter 17, the fifth back component 55 pushes the seventh back component 57, and the seventh back component 57 drives the angle adjustment component 510 to rotate relative to the back plate 59, thereby realizing the angle adjustment of the back assembly 50.

[0065] The elderly chair bracket 100 provided by the present invention and the angle adjustment of the back assembly 50 can satisfy the user's various usage postures and improve the user's comfort.

[0066] Please also refer to Figure 13 and Figure 14 , Figure 13 for Figure 1 The structural diagram of the lifting component 60 in the elderly chair bracket 100 is shown. Figure 14 for Figure 1The figure shows a schematic diagram of the raised state of the elderly chair support 100. The elderly chair support 100 further includes a lifting assembly 60, which includes a fixing member 61, a first lifting member 62, and a second lifting member 63. The fixing member 61 is fixedly connected to the base 10. The first end of the first lifting member 62 is hinged to the sixth transmission member 36, and the second end of the first lifting member 62 is hinged to the fixing member 61. The first end of the second lifting member 63 is hinged to the sixth transmission member 36, and the second end of the second lifting member 63 is hinged to the fixing member 61. The first lifting member 62 and the second lifting member 63 are spaced apart.

[0067] When the driving member 21 drives the guide part 351 to be placed in the guide groove 361 close to one end of the leg assembly 40, the leg assembly 40 is in a retracted state, and the driving member 21 continues to drive the guide part 351. The guide part 351 abuts against the side wall of the guide groove 361, and causes the sixth transmission member 36 to rotate relative to the fixed member 61 through the first lifting member 62 and the second lifting member 63. The lifting part 362 pulls the adapter 17. Since the first transmission assembly 30, the leg assembly 40 and the back assembly 50 are all connected to the adapter 17, the adapter 17 is lifted and rotated relative to the base 10, thereby realizing the height adjustment of the elderly chair bracket 100.
