TECHNICAL FIELD

[0001] The utility model relates to an electric wheelchair, especially an electric suitcase chair. BACKGROUND

[0002] The existing electric wheelchair is folded left and right, although the width is narrow, but the height is high. It is inconvenient to take the plane and high-speed rail because it exceeds the boarding size. The height does not increase when folding, but it is not firm in the unfolded state, and it will collapse when sitting on it. SUMMARY

[0003] To solve the above technical problems, the utility model aims at providing an electric suitcase chair.

[0004] The utility model discloses an electric suitcase chair, which adopts the following scheme: the folding shaft 17 of the cross rod connecting the main frame is on the folding lug 16 on the upper part of the main frame 8, and the positioning connecting piece 7 is in the lower half of the cross rod; the top bar 1 is connected with the cross rod 2 through the top bar shaft 3, the top column 5 is fixed with the other side cross rod 6, and the top bar 1 is just pressed against the top column 5 when the electric suitcase chair is unfolded.

[0005] Through the above scheme, the electric suitcase chair has the following advantages: the height does not increase when folding, and it is firm in the unfolded state and will not collapse when sitting on it. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0010] The specific embodiments of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to

[0011] The utility model is described, but is not used to limit the scope of the utility model.

[0012] Referring to Figure 1 , including 2 main frames 8, 2 universal wheels and 2 drive wheels and a battery and a controller, there is one main frame 8 on the left and right, and each main frame is a generally rectangular frame, including upper rods, lower rods, front rods and rear rods, and is welded together, and one universal wheel and one drive wheel are installed on the front and rear of each main frame below. The cross rod 2 is connected with the main frame 8 of the other side cross rod 6. The folding pivot 17 of the cross rod connecting the main frame is on the folding lug 16 of the upper rod of the main frame, and the positioning connecting piece 7 is on the lower part (opposite to the wheelchair, and the folding pivot of the cross rod connecting the main frame is on the folding lug of the lower rod of the main frame, and the positioning connecting piece is on the upper part).

[0013] Referring to Fig. 2, the top bar 1 is connected with the cross rod 2 through the pivot 3 of the top bar, the top column 5 is fixed with the other side cross rod 6 through the fixing bar 4 on the other side cross rod, and the electric box bag chair is in the unfolded state. When the top bar 1 is turned flat and just presses against the top column 5, the seat is pulled, and the top bar and the top column are pressed, so that it is very firm.

[0014] Referring to Fig. 3, before folding, the top bar is first pulled upwards, so that it can be freely folded.

[0015] Referring to Figure 1 , the backrest tube 19 is inserted with the pull rod 20, the pull rod 20 is provided with the handle 18, the handle 18 is provided with the pull rod button 25, so that when the electric box bag chair is pushed and pulled, the height can be freely adjusted.

[0016] Referring to Figure 2 and Figure 3 , the backrest tube 19 is folded by rotating the backrest rotating shaft 24, and the backrest tube 19 is positioned by the knob plunger 23 to prevent the backrest from tilting backward and forward. The knob plunger is ready-made. Because the backrest relies on a large force, a backrest positioning column 31 can also be added to stabilize the backrest tube 19 and prevent it from tilting backward.

[0017] Referring to Fig. 1 Figure 2 and Fig. 3, the armrest 21 rotates on the armrest lug 22 in the middle of the backrest tube 19 and can be turned upwards. As can be seen from Fig. 2 and Figure 3 , the armrest 21 is close to the backrest tube 19, the upper edge is arc-shaped, and the lower edge is straight, so it can only be turned up and fall flat, preventing it from being folded downward.

[0018] Referring to Figure 1 Figure 2 and Figure 3 , the parking device 9 can be composed of a knob plunger, so it is light and small.

[0019] Referring to Fig. 1 Fig. 2 and Figure 3 , the footrest 15 can be flipped up along the footrest pivot 29. When falling, the footrest positioning post 30 is latched.

[0020] Referring to Figure 1 Fig. 2 and Figure 3 , the backrest cloth is connected between the two backrest tubes, that is, the backrest cloth position 26. The seat cloth is connected between the two main frame upper tubes, that is, the seat cloth position 27. The storage bag position is between the lower tubes of the single-side main frame.
