Embodiment 1

[0040] Such as figure 1 and 2 As shown, the seat that can assist the human body to sit up in this embodiment includes a seat frame and a seat surface 2 .

[0041] The seat frame includes a base 1 and a telescopic support mechanism arranged on both sides of the base. The telescopic support mechanism includes a push rod 3, a rear vertical bar 4, a front vertical bar 5, an upper cross bar 6 and a lower cross bar 7. One end of the vertical bar 4 is fixedly arranged on the base 1, and is vertically arranged on the base 1 near the rear side, and the front vertical bar 5 is arranged vertically, and is positioned at the top of the base near the middle. The two ends of the upper cross bar 6 and the lower cross bar 7 are respectively hinged with the front vertical bar 5 and the rear vertical bar 4 to form a parallel four-bar linkage mechanism. The push rod 3 is arranged on the base 1, and the push rod 3 drives the upper cross bar 1. The lower cross bar swings up and down along the hin...

Embodiment 2

[0056] The difference between the seat in the present embodiment and the first embodiment is that the structure of the transmission mechanism adopted is different, as follows:

[0057] Such as Figure 5 As shown, the transmission mechanism 8 in this embodiment includes a second external gear 811 fixedly arranged on one side of the seat surface and a second driving gear 812 fixedly arranged on the hinge shaft, the second external gear 811 and the second The driving gears 812 are engaged with each other.

[0058] When the push rod drives the upper cross bar to rotate, it drives the hinge shaft fixedly connected with the upper cross bar to rotate, so that the second driving gear on the hinge shaft rotates synchronously, and the second driving gear drives the second external gear to rotate, thereby driving the seat surface to rotate .

Embodiment 3

[0060] The difference between the seat in the present embodiment and the first embodiment is that the structure of the transmission mechanism adopted is different, as follows:

[0061] Such as Figure 6 As shown, the transmission mechanism 8 in this embodiment includes a third external gear 821 fixedly arranged on one side of the seat surface, a third synchronous wheel 822 meshing with the third external gear, a third intermediate wheel 823 and a third intermediate gear 823. The third transmission wheel 824 meshed with the wheels; the third synchronous wheel 822 and the third intermediate wheel 823 are fixedly arranged on the hinge shaft 806 respectively, and the third transmission wheel 824 is fixedly arranged on the upper cross bar 6 through the gear shaft 807 .

[0062] When the push rod drives the upper cross bar to rotate, the third intermediate wheel rotates under the action of the third transmission wheel, the third intermediate wheel drives the third synchronous wheel...

Abstract

The invention discloses a seat capable of assisting in standing and sitting of the human body. The seat comprises a seat frame and a seat surface; the seat frame comprises a base and telescopic supporting mechanisms arranged at the two sides of the base, each telescopic supporting mechanism comprises a push rod, a rear vertical rod, a front vertical rod, an upper transverse rod and a lower transverse rod, the two ends of each upper transverse rod and the two ends of each lower transverse rod are hinged to the corresponding front vertical rod and the corresponding rear vertical rod respectivelyto form a parallel four-bar mechanism, and the push rods drive the upper transverse rods and the lower transverse rods to swing up and down along hinged points between the upper and lower transverserods and the rear vertical rods; and the two sides of the seat surface are hinged to the front vertical rods located at the two sides of the seat surface respectively, and a transmission mechanism drives the seat surface to rotate along hinged points between the seat surface and the front vertical rods when the upper transverse rods swing. According to the invention, by combination with a human engineering principle, lower limb motion of the human body is copied in an action process, a standing-sitting path of the human body is fitted, and whole-course boosting acting force is provided in theprocess, so that the problem that people with weak standing and sitting due to knee joint pain, degeneration and the like are inconvenient in standing and sitting can be well solved.

Description

technical field [0001] The invention relates to the field of life assistance devices, in particular to a seat that can assist a human body to sit up. Background technique [0002] As we all know, the legs are an extremely important part of the human body structure, through the knee joint structure to complete various compound movements, such as walking up and sitting up, etc. However, simple daily routines such as going to the toilet and taking a bath often give them headaches. In order to improve the quality of life of this group of people and reduce the burden on their families, the seat that can automatically assist the human body to sit up is urgently to be developed. [0003] At present, the auxiliary rising seat in the current technology, such as a fully automatic auxiliary device for sitting up in the patent document CN201510192873.1, uses a push rod to make the seat surface rise and fall to fit the human body; The manufacturing cost of the cylinder is relatively hi...
