[0067] See also Figure 3 and Figure 4 , and see also Figure 1 and Figure 2 ,in Figure 3 Draw Figure 1 A partial exploded schematic diagram of a first guide assembly 1200 of the stair lift chair 1000 of the embodiment, Figure 4 The diagram shows a partial front view of the first guide frame 1210 of the stair lift chair 1000 of the embodiment. In order to facilitate the replacement of the first cleaning member 1220, the first cleaning member 1220 is detachably connected to the first guide frame 1210. Figures 1 to 4 As shown, the first cleaning member 1220 can be connected to the first guide frame 1210 in a locking manner.
[0068] Specifically, the first guide frame 1210 may include a first frame body 1211 and a first locking piece 1212. The first frame body 1211 may be connected to the chair 1100 and include an upper cover 1211a, a lower cover 1211c and a first back plate 1211b, and the upper cover 1211a, the lower cover 1211c and the first back plate 1211b are locked to surround the first internal space S1. The first locking piece 1212 may be located in the first frame body 1211 and protrude from the first back plate 1211b of the first frame body 1211. The first cleaning member 1220 may be located in the first frame body 1211 and locked to the first locking piece 1212.
[0069] The upper cover 1211a and the lower cover 1211c are both rectangular frame-shaped and respectively include two upper side portions and two lower side portions opposite to each other in a longitudinal direction (parallel to the X-axis). The first locking piece 1212 is adjacent to an upper side portion and a lower side portion of one side and is spaced apart from the upper side portion and the lower side portion to separate a groove. Thus, when the two screws 1240 lock the first cleaning member 1220 to the first guide frame 1210, the first cleaning member 1220 can be located in the groove.
[0070] Furthermore, the first guide assembly 1200 may actually include two first cleaning members 1220, and the two first cleaning members 1220 are detachably connected to two sides of the first guide frame 1210. Therefore, the number of the first locking pieces 1212 is also two for locking the two first cleaning members 1220, and two grooves can be separated on two sides of the first guide frame 1210 to accommodate the two first cleaning members 1220.
[0071] like Figure 2 and Figure 3 As shown, the first locking piece 1212 may have a C-shaped structure, and the first cleaning member 1220 may include a C-shaped body 1221 and a plurality of first bristles 1222. The C-shaped body 1221 corresponds to the first locking piece 1212 and includes an opening 1221a, and the opening 1221a is for the first track R1 to pass through. The aforementioned plurality of first bristles 1222 protrude from the C-shaped body 1221 into the opening 1221a to contact the first outer surface R11 of the first track R1. Since the cross section of the first track R1 is circular and is accommodated in the first internal space S1 of the first guide frame 1210, the shapes of the first locking piece 1212 and the first locking piece 1212 are both matched with the first track R1. In addition, in order to facilitate the replacement of the first cleaning member 1220, the minimum distance between the two free ends of the C-shaped body 1221 will be greater than the diameter of the first track R1, and the first cleaning member 1220 can be pulled out and replaced after the screw 1240 is loosened. In other embodiments, the first cleaning member may also have a brush structure or a C-shaped cleaning strip structure, and may remove dust by friction, but the present invention is not limited thereto.
[0072] The first guide assembly 1200 may further include a plurality of first guide wheels 1230, which may be disposed in the first frame 1211 and configured to rollably contact the first track R1.
