[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] like Figures 1 to 4 As shown, the integrated electric backrest includes a frame body connected in an integrated manner, the frame body includes a first crossbar 1 and a second crossbar 2, both sides of the second crossbar 2 are connected with side panels 3, the upper ends of the side panels 3 are connected with linkage components, and the linkage components are connected to the first crossbar 1; the side panels 3 are provided with a first fixing portion, and the linkage component is provided with a second fixing portion; the first fixing portion is used to connect the back panel 7, and the second fixing portion is used to connect the head panel 8; therefore, in the structure of the present application, the first crossbar 1, the second crossbar 2, the side panels 3 and the linkage component can be fixed into a fixed frame body, which can be directly fixed and installed with the back panel 7 and the head panel 8, and the driving component 4 can be installed between the first crossbar 1 and the second crossbar 2 later; that is, the distance between the first crossbar 1 and the second crossbar 2 is fixed, and the driving component 4 is a standard part purchased or customized according to the distance between the first crossbar 1 and the second crossbar 2, and the installation is very convenient, simple and fast. The driving component 4 can be a cylinder or an electric push rod. In this embodiment, an electric push rod is used.

[0024] The upper end of the driving member 4 is hinged to the first crossbar 1, and the lower end of the driving member 4 is hinged to the second crossbar 2; therefore, the movement of the driving member 4 will drive the first crossbar 1 to move, thereby pulling the linkage member to move; the driving member 4 drives the electric backrest to move Figure 1 or Figure 2 The state can be freely switched to adjust different inclination angles of the head plate 8.

[0025] The linkage component includes a first connecting rod 9, a second connecting rod 10 and a support member 11; the lower ends of the first connecting rod 9 and the second connecting rod 10 are both rotatably connected to the side panels 3, and the upper ends of the first connecting rod 9 and the second connecting rod 10 are both rotatably connected to the support member 11; the first cross bar 1 is connected to the first connecting rod 9 near the middle position, so when the driving component 4 pulls the first cross bar 1, it will act on the first connecting rod 9, thereby driving the angle movement of the support member 11.

[0026] In this embodiment, the first fixing portion and the second fixing portion are both mounting holes, that is, the back panel 7 is fixed to the first fixing portion provided on the side panel 3 by adding screws, and the head panel 8 is fixed to the support member 11 by adding screws, so as to adjust the change in the angle of the support member 11, that is, adjust the change in the angle of the head panel 8.

[0027] The first crossbar 1 has a vertically arranged ear 101, which is extended outward. The upper end of the driving member 4 is hinged to the outer end of the ear 101. Figure 1 as well as Figure 2 It can be seen that the ear 101 is extended, that is, by pulling the outer end of the ear 101 through the driving member 4, the first cross bar 1 and the first connecting rod 9 can be rotated; because a headrest needs to be installed on the support member 11 in the later use, and the human body bears a large weight after sitting on it, the extension of the ear 101 increases the torque of the driving member 4, which can make the driving member 4 drive the support member 11 to move with a smaller force.

[0028] The support member 11 is a right-angle member, has good support strength, and is not easily deformed.

[0029] The first cross bar 1 and the second cross bar 2 are square tubes; a first angle code 5 is provided at the connection between the second cross bar 2 and the side panel 3; a second angle code 6 is provided at the connection between the first cross bar 1 and the first connecting rod 9; the setting of the first angle code 5 and the second angle code 6 facilitates the connection of the two connected components; the first cross bar 1 and the second cross bar 2 are square tubes, which not only have good force resistance, but also facilitate the connection and fixation of the angle codes.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
