[0003] However, the aforementioned seats, including some existing seats, are generally designed with a single function in mind. Their shapes are fixed or their adjustment range is limited, making it difficult to meet users' needs for multifunctionality and spatial adaptability. Therefore, we propose a deformable seat based on shape memory alloy. Utility Model Content

[0004] The purpose of this invention is to provide a deformable seat based on shape memory alloy, which can solve the problem of limited functionality in some existing seats.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformable seat based on shape memory alloy, comprising:

[0006] A seat with a backrest hinged to it;

[0007] The armrest mechanism, which is installed on the seat, is designed to accommodate the support height of users of different heights;

[0008] The support mechanism is located on the rear side of the back plate. The support mechanism includes support legs. Two sets of grooves are provided on the rear side of the back plate. A set of support legs is rotatably installed between the inner walls of the two sets of grooves. A set of first damping plates is provided at the pivot of each set of support legs.

[0009] Preferably, the support mechanism further includes limiting blocks. Two sets of limiting blocks are rotatably mounted on the rear outer surface of the backrest. Each set of limiting blocks has a second damping plate fixedly mounted on it, which fits against the corresponding support leg. With the combined action of the seat, backrest, and support mechanism, the seat can be transformed into a bed for the user to lie down and rest. This solves the problem that some existing seats are generally designed with a single function in mind, and their shape is fixed or the adjustment range is limited, making it difficult to meet the user's needs for multi-functionality and spatial adaptability, thus improving the practicality of the seat.

[0010] Preferably, the armrest mechanism includes a fixed sleeve, a sliding plate, an armrest pad, a plug rod, a handle, and a spring. A set of fixed sleeves is fixedly installed on both outer surfaces of the seat. A set of sliding plates is slidably installed inside each of the two sets of fixed sleeves. An armrest pad is fixedly installed on the top of each of the two sets of sliding plates. At least two sets of plug holes are provided on one side of each of the two sets of sliding plates. A set of plug rods movably passes through one side of each of the two sets of fixed sleeves. One end of each set of plug rods is inserted into a corresponding plug hole. A handle is fixedly installed on the other end of each set of plug rods. Both ends of each set of plug rods are fixedly connected to a corresponding handle and a corresponding fixed sleeve. Under the action of the armrest mechanism, the height of the armrest pad can be adjusted according to the user's different heights, improving the flexibility of the seat, ensuring the seat's usability, and facilitating the promotion and use of the seat.

[0011] Preferably, both the seat and backrest are fitted with a set of soft padding, with SMA components (such as springs, wires, or sheets) embedded inside. The SMA is triggered by temperature or pressure to undergo a phase change. When external stimuli (such as human body pressure or changes in ambient temperature) are detected, the SMA can automatically restore a preset shape, realizing dynamic adjustment of the seat back angle, seat cushion curvature, or support strength. For example, when a pressure sensor detects that a passenger has sat down, the SMA is heated and contracts, driving the slide rail mechanism to make the seat conform to the curve of the human body.

[0012] Preferably, at least two sets of chair legs are fixedly installed at the bottom of the seat.

[0013] Preferably, a sliding groove is provided on the rear outer surface of the backrest, a retaining sleeve is slidably installed on the sliding groove, and a shaping plate is hinged to the bottom of the seat plate, with part of the shaping plate inserted into the retaining sleeve.

[0014] Preferably, a headrest is fixedly installed on the front side of the backrest.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The deformable seat based on shape memory alloy can be transformed into a bed for users to lie down and rest through the cooperation of the seat, backrest and support mechanism. This solves the problem that some existing seats are generally designed with a single function as the guide, and their shape is fixed or the adjustment range is limited, making it difficult to meet users' needs for multi-functionality and spatial adaptability, thus improving the practicality of the seat.

[0017] (2) The deformable seat based on shape memory alloy can adjust the height of the armrest pad according to the different heights of the users through the armrest mechanism, which improves the flexibility of the seat, ensures the use effect of the seat, and is conducive to the promotion and use of the seat.
