DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. It should be noted that the description of the embodiments is used to help understand the present application, but does not constitute limitation on the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] Referring to Figures 1 to 4 Fig. 1, a seat lifting chair frame structure includes a mounting frame 1, a first telescopic drive 2, and a jacking frame 3 and a seat frame 4 rotatably connected to the front end of the mounting frame 1. The first telescopic drive 2 is rotatably connected to the lower end of the mounting frame 1. The jacking frame 3 includes a pushing portion 31 and a connecting portion 32. The pushing portion 31 is held on the bottom surface of the seat frame 4. The pushing portion 31 is rotatably connected to the telescopic end of the first telescopic drive 2. The telescopic end of the first telescopic drive 2 is telescoped to switch the seat frame 4 between an initial position and a lifting position.

[0024] Referring to Figure 1 Fig. 2, a user can adjust the inclination angle of the seat frame 4 by controlling the telescopic amount of the first telescopic drive 2. The first telescopic drive 2 is preferably a servo electric cylinder. When the first telescopic drive 2 is extended to the maximum stroke, the seat frame 4 is overlapped with the mounting frame 1. At this time, the seat frame 4 is in the initial position.

Figure 1 The mounting frame 1 is provided with a backrest mounting part 12, and when the sitting part frame 4 is in the initial position, the angle between the sitting part frame 4 and the horizontal plane is greater than 180°, so when the user leans against the backrest mounting part 12 and stands up with the help of the first telescopic driving part 2, the setting of the hip supporting part 42 can prevent the user from sliding along the inclined angle of the seat cushion mounting part 41 in the initial stage of standing up.

[0028] The mounting frame 1 is provided with a recess 13 for accommodating the hip supporting part 42, as shown in the figures. Figure 1 Figure 2 When the sitting part frame 4 is in the initial position, the hip supporting part 42 is embedded in the recess 13, so that when the user leans against the backrest mounting part 12 of the mounting frame 1, the hip supporting part 42 does not excessively press against the user's back, waist or hips, thereby avoiding the user's discomfort.

[0029] The sitting part frame 4 further comprises a rotating plate 43, one end of the rotating plate 43 is rotatably connected to the seat cushion mounting part 41, specifically, the rotating plate 43 is connected to the seat cushion mounting part 41 through a hinge, and a mechanical switch 44 is arranged at the lower end of the rotating plate 43, the mechanical switch 44 can be a pressure sensor, etc. When the seat lifting chair frame structure is applied to a shared massage chair, the seat of the shared massage chair is provided with a lifting mechanism, which can lift the person who occupies the massage chair but does not consume the use. The mechanical switch 44 provides an electrical signal to the control module of the lifting mechanism.

[0030] Further comprising a bottom frame 5, a second telescopic driving part 6, and a plurality of driven swing rods 7 for connecting the mounting frame 1 and the bottom frame 5, the second telescopic driving part 6 is rotatably connected to the bottom frame 5, and the telescopic end of the second telescopic driving part 6 is rotatably connected to the front end of the mounting frame 1, the inclination angle of the mounting frame 1 can be changed by adjusting the telescopic amount of the second telescopic driving part 6, and the user can use the seat lifting chair frame structure in a sitting position or a lying position by adjusting the inclination angle of the mounting frame 1, thereby meeting the diversified use requirements of the user.

[0031] ​The mounting frame 1 comprises a front cross beam 11, an inner end surface of the front cross beam 11 is provided with two first fixing sheets 111 for hingedly connecting the jacking frame 3, and two second fixing sheets 112 for hingedly connecting the telescopic ends of the second telescopic driving members 6, the first fixing sheets 111 are rotatably connected with the jacking frame 3, and the second fixing sheets 112 are connected with the second telescopic driving members 6, so that the overall structure is compact.
