[0027] Please see Figure 1 An electric chair includes a chair frame 1, with armrests 2 installed on both sides of the chair frame 1, and the armrests 2 on both sides having the same structure. Please refer to [link / reference]. Figure 2The handrail 2 includes a box section 21 and a die-cast section 22. The main body of the box section 21 is made of wood, while the die-cast section 22 is made of die-cast metal and is hollow inside. The box section 21 and the die-cast section 22 are detachably connected. When the box section 21 and the die-cast section 22 are disassembled, the box section 21 can be placed inside the die-cast section 22. Therefore, during packaging and transportation, the box section 21 and the die-cast section 22 can be disassembled first, and the box section 21 can be placed inside the die-cast section 22, so that the box section 21 and the die-cast section 22 overlap, reducing the packaging volume and lowering transportation costs.

[0028] The armrest 2 is detachably mounted on the chair frame 1. During packaging and transportation, the entire armrest 2 can be detached from the chair frame 1 first, and then the die-cast part 22 and the box part 21 of the armrest 2 can be disassembled separately, thus minimizing the packaging volume and reducing transportation costs.

[0029] For details, please refer to Figure 3 The box section 21 includes a straight plate 211 and two identical semi-elliptical plates 212. The two semi-elliptical plates 212 are parallel to each other and spaced apart, with their straight edges fixed to the straight plate 211. The two semi-elliptical plates 212 can also be reinforced by wooden blocks (not shown in the figure). Correspondingly, the die-casting section 22 is a plate bent into a semi-elliptical shape, with both ends of the die-casting section 22 detachably connected to both ends of the straight plate 211. This structural arrangement of the box section 21 facilitates assembly and allows for easy stacking and packaging of the box section 21 and the die-casting section 22.

[0030] Please see Figure 4 The straight plate 211 has baffles 213 on both sides. The length direction of the baffles 213 is the same as that of the straight plate 211, and both baffles 213 are located on the same side of the straight plate 211 near the semi-elliptical plate 212. The outer side of the semi-elliptical plate 212 is in close contact with the inner side of the baffles 213. This arrangement facilitates the assembly of the box 21, and the baffles 213 can assist in positioning the semi-elliptical plate 212.

[0031] Please see Figure 2 and Figure 3 The handrail 2 also includes a connecting piece 23, which is detachably connected to the housing 21 and the die-casting part 22, thereby achieving a detachable connection between the housing 21 and the die-casting part 22. Specifically, the connecting plate has multiple holes, including a semi-elliptical plate 212. The two ends of the die-casting part 22 have a certain thickness and corresponding holes. By screwing a connector (such as a screw) through the holes on the connecting plate into the holes on the die-casting part 22 and the semi-elliptical plate 212, the connector can be connected to the die-casting part 22 and the housing 21. By setting the connecting piece 23, the structure of the handrail 2 is simplified, and assembly is more convenient and quick.

[0032] Please see Figure 1 The chair frame 1 has a backrest 3 installed at its rear end. The backrest 3 includes a base frame (not shown in the figure) and foam-filled shaped cotton (not shown in the figure) fixed to the base frame. Existing backrests 3 typically use an iron frame as a base, then attach wooden blocks to the iron frame, and finally cover it with a layer of cotton. In this embodiment, however, shaped cotton is used instead of the traditional wooden block method; the shaped cotton is directly foamed and fixed to the iron frame, thus simplifying the production process and reducing manufacturing costs.

[0033] Please see Figure 1 The upper end of the backrest 3 is equipped with an adjustable headrest 4. It is easy to understand that the backrest 3 supports the user's back, while the headrest 4 supports the user's head. Making the headrest 4 adjustable allows the user to easily adjust its height according to their own needs for greater comfort.

[0034] In addition, the headrest 4 is detachable from the backrest 3. On the one hand, users can easily install or remove the headrest 4 according to their own needs during use; on the other hand, the headrest 4 can be disassembled during packaging and transportation, reducing packaging volume.

[0035] Please see Figure 1 , Figure 5 and Figure 6 The electric chair also includes a backrest drive mechanism 5 and a backrest adjustment mechanism 6. The backrest drive mechanism 5 is mounted on the chair frame 1, and the backrest adjustment mechanism 6 is movably mounted on the rear end of the chair frame 1 and connected to the output end of the backrest drive mechanism 5. The lower end of the backrest 3 is connected to the backrest adjustment mechanism 6, and the backrest drive mechanism 5 can adjust the angle between the backrest 3 and the chair frame 1 through the backrest adjustment mechanism 6. The backrest drive mechanism 5 and the backrest adjustment mechanism 6 enable electric adjustment of the backrest 3, providing convenience for the user.

[0036] Please see Figure 1 , Figure 5 and Figure 6 The electric chair also includes a leg rest bracket 7, a leg rest drive mechanism 8, and a leg rest telescopic mechanism 9. The leg rest drive mechanism 8 is mounted on the chair frame 1, and the leg rest telescopic mechanism 9 is movably mounted on the chair frame 1 and connected to the output end of the electric leg rest drive mechanism 8. The leg rest bracket 7 is mounted at the end of the leg rest telescopic mechanism 9 near the front of the chair frame 1, and the leg rest drive mechanism 8 can drive the leg rest telescopic mechanism 9 to extend or retract to adjust the leg rest bracket 7 to rise or fall. Through the arrangement of the leg rest drive mechanism 8 and the leg rest telescopic mechanism 9, the electric adjustment of the leg rest bracket 7 can be achieved.

[0037] When the leg support drive mechanism 8 extends the leg support telescopic mechanism 9, the leg support telescopic mechanism 9 can lift the leg support bracket 7, allowing the leg support plate mounted on the leg support bracket 7 to support the user's legs. When the leg support drive mechanism 8 retracts the leg support telescopic mechanism 9, the leg support telescopic mechanism 9 can retract the leg support bracket 7. When the backrest drive mechanism 5 rotates the backrest adjustment mechanism 6 forward of the chair frame 1, the backrest adjustment mechanism 6 can tilt the backrest 3 backward (increasing the angle between the backrest 3 and the chair frame 1). When the backrest drive mechanism 5 rotates the backrest adjustment mechanism 6 backward of the chair frame 1, the backrest adjustment mechanism 6 can rotate the backrest 3 forward (decreasing the angle between the backrest 3 and the chair frame 1). In practical applications, the user can control the leg support drive mechanism 8 independently to control the lifting or retraction of the leg support bracket 7; they can also control the backrest drive mechanism 5 independently to adjust the angle of the backrest 3; or they can control both the leg support drive mechanism 8 and the backrest drive mechanism 5 simultaneously to adjust both the leg support bracket 7 and the backrest 3.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
