[0025] The specific configuration and function of this embodiment are described in detail below. The seat is composed of a backrest 1 and a base 2. The backrest 1 and the base 2 are connected together through a connecting assembly 4. The control switch of the electric cylinder 44 in the connecting assembly 4 is set on the armrests on both sides of the base 2. When it is necessary to stand up from the seat, the switch of the electric cylinder 44 is started. At this time, the battery module 47 supplies power to the electric cylinder 44. When the piston rod in the electric cylinder 44 is extended, it will directly push the cross bar 46 to move upward;

[0026] The cross bar 46 is connected to the first connecting plate 41 on the back of the backrest 1 through the reinforcement plate 45. When the cross bar 46 is pushed, it will drive the backrest 1 to move diagonally upward. At this time, the backrest 1 and the support plate 3 at its bottom will move together. The support plate 3 is used to assist people in standing up, thereby accelerating the standing speed of people. The electric cylinder 44 is installed on the fixed plate 43, and the fixed plate 43 is connected to the base 2 through the second connecting plate 42, wherein the second connecting plate 42 and the first connecting plate 41 are connected to the base 2 and the backrest 1 by screws, and the second connecting plate 42 and the fixed plate 43 and the first connecting plate 41 and the cross bar 46 are connected by welding to ensure the structural strength of the foundation. Embodiment 2

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting rod 48 is fixedly installed at the junction of the fixed plate 43 and the second connecting plate 42, and positioning tubes 49 are fixedly installed at both ends of the limiting rod 48.

[0029] When the electric cylinder 44 pushes the cross bar 46 to move upward, the reinforcement ring 414 will move along the direction of the guide plate 410 to ensure the stability of the cross bar 46 during movement. The guide plate 410 can determine the moving direction of the cross bar 46 to ensure that the change in the height of the backrest 1 can help people stand up quickly.

[0030] The use method and working principle of the device: The seat is composed of a backrest 1 and a base 2, and the backrest 1 and the base 2 are connected together through a connecting component 4. Under normal conditions, the connecting ends 413 at both ends of the crossbar 46 are built into the receiving groove 411 of the positioning tube 49 to ensure the connection stability between the backrest 1 and the base 2. When a person needs to stand up from the seat, the switch of the electric cylinder 44 is started. At this time, the battery module 47 supplies power to the electric cylinder 44. When the piston rod in the electric cylinder 44 extends, it will directly push the crossbar 46 to move upward, and use the crossbar 46 to drive the backrest 1 to move upward;

[0031] When the electric cylinder 44 pushes the cross bar 46 to move upward, the reinforcement ring 414 will move along the direction of the guide plate 410 to determine the moving direction of the backrest 1. In this process, the backrest 1 and the support plate 3 at its bottom will move together, and the support plate 3 is used to assist people in standing up, thereby speeding up the standing speed of people.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
