DETAILED DESCRIPTION

[0021] 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.

[0022] Please refer to the attached Figure 1-6The utility model provides a wheelchair armrest state adjustment device, comprising a wheelchair frame 100, a backrest frame 200 is fixed on the top of the wheelchair frame 100, a walking wheel 300 is arranged at the bottom of the wheelchair frame 100, a battery 400 is fixed to the rear end of the wheelchair frame 100, an armrest 500 is fixed to one side of the backrest frame 200, a controller 600 is fixed to the front end of the armrest 500, a support plate 510 is fixed to the front end of the armrest 500, the controller 600 is fixedly installed on the top of the support plate 510, the battery 400 is electrically connected to the controller 600, and the other side of the backrest frame 200 is connected to the armrest 2 700 through an adjustment component;

[0023] The adjustment assembly includes a rotating rod 710, the rear end of which is rotatably connected to the side end of the backrest frame 200 through a pin 712, and the side end of the backrest frame 200 is also rotatably connected to an electric push rod 720, which is located below the rotating rod 710 and is electrically connected to the controller 600. Specifically, the user can control the operation of the electric push rod 720 through the controller 600;

[0024] A fixing plate 711 is fixed to the bottom of the front end of the rotating rod 710, and a connecting plate 721 is connected to the output shaft of the electric push rod 720. The connecting plate 721 and the fixing plate 711 are rotatably connected through a pin 722. Specifically, when the electric push rod 720 is running, the rotating rod 710 can be driven to rotate through the connecting plate 721 and the fixing plate 711, thereby controlling the rotating rod 710 from a horizontal state (such as Figure 3 Adjust to a vertical position (as shown) Figure 6 shown);

[0025] The output shaft of the electric push rod 720 is fixed with a screw rod 723, and a positioning nut 724 is threadedly connected to the surface of the screw rod 723. The end of the screw rod 723 away from the electric push rod 720 passes through the end of the connecting plate 721. It should be noted that a hole (not shown in the figure) is opened at the end of the connecting plate 721 for inserting the end of the screw rod 723. The user can adjust the position of the positioning nut 724 on the screw rod 723 by rotating the positioning nut 724 to control the insertion depth of the screw rod 723.

[0026] The top of the rotating rod 710 is fixed with an armrest housing 730, and the fixing plate 711, the electric push rod 720, and the connecting plate 721 are all located inside the armrest housing 730. Specifically, the armrest housing 730 of the armrest 2 700 can be rotated and adjusted synchronously with the rotating rod 710, so that it can be adjusted from a horizontal state (such as Figure 1 As shown) adjusted to a vertical position (as shown) Figure 2 shown);

[0027] In summary, the device can effectively prevent the armrest 2 700 from blocking the space of the wheelchair, thereby expanding the space for users to get on and off the wheelchair, that is, it is convenient for users to get on and off the wheelchair, and it is convenient to use.

[0028] The use process of the utility model is as follows: before the user sits on the wheelchair or prepares to get off the wheelchair, the user can control the electric push rod 720 to operate through the controller 600. When the electric push rod 720 operates, the connecting plate 721 and the fixing plate 711 can drive the rotating rod 710 to rotate, thereby controlling the rotating rod 710 to change from a horizontal state (such as Figure 3 Adjust to a vertical position (as shown) Figure 6 As shown), the armrest housing 730 of the armrest 2 700 can be rotated and adjusted synchronously with the rotating rod 710, so that it can be adjusted from a horizontal state (as shown in FIG. Figure 1 As shown) adjusted to a vertical position (as shown) Figure 2 As shown), the device can effectively prevent the armrest 2 700 from blocking the space of the wheelchair, thereby expanding the space for users to get on and off the wheelchair, that is, it is convenient for users to get on and off the wheelchair, and it is convenient to use.

[0029] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
