The armrest structure is provided with a hook, which can facilitate the user to hang some articles for immediate use.

The lower part of the armrest structure is provided with a card slot, and the card slot is a reverse concave opening; the armrest can be rotated forward and backward relative to the steel pipe. When it is rotated backward, it can form a backrest. When it is rotated forward , when the user slides, the stability and safety of the user can be increased.

The ball screw is provided with a motor, a fixed housing, a shaft coupling, a screw rod, and balls; the motor reaches the coupling through the fixed housing, and one end of the screw rod is also arranged in the coupling, and the motor The rotation drives the rotation of the screw rod; the ball is arranged on the screw rod.

The lift button is a second gear switch, which is an upper gear and a lower gear respectively, and the front gear controls the rising of the lifting structure; the lower gear controls the descending of the lifting structure.

A battery is arranged in the battery box, and the battery provides power for the whole device.

Described leg support is provided with 3, and wheel is universal wheel.

The control direction button is a 360° rotary switch, which can effectively control the direction of the wheels.

The brake pads are arranged above the wheels, and when the user needs the wheelchair not to move at all, the brake pads can be used to fix the wheels, so that the stability of the chair can be effectively guaranteed.

The beneficial effects of the utility model:

The utility model is simple in structure, compact and convenient, suitable for home use, can effectively lift and control the direction, and is convenient for the user to take things; and can realize the automatic driving of the wheelchair by controlling the direction button, saving the physical strength of the user.

detailed description

The utility model is described in detail below in conjunction with accompanying drawing

According to shown in Figure 1, the utility model comprises handrail structure 1, and handrail structure 1 is provided with lifting button 2, hook 3; Described hook 3 is used for hanging some temporary items; Fixed; the lifting structure 5 is provided with a ball screw, and the ball screw is provided with a motor 6, a fixed shell 7, a coupling 8, a screw rod 9, and a ball 10; the motor 6 reaches through the fixed shell 7 In the coupling 8, one end of the screw rod 9 is also arranged in the coupling 9, and the ball 10 is arranged on the screw rod 9; the ball 10 is provided with a connecting rod 11, and the connecting rod 11 passes Nut and seat surface 12 are fixed; The bottom of described lifting structure 5 is provided with battery box 13; Described battery box 13 is provided with battery, and described battery is the motor 6 power supply in lifting structure 5, and described lifting button 2 controls motor 6 rotation; the bottom of the battery box 13 is provided with three leg supports 14, and the three leg supports 14 are respectively provided with universal wheels 15; the armrest structure 1 is also provided with a control direction button 16, so The control direction button 16 is also connected with the battery in the battery box 13, and forms a control circuit with the universal wheel 15. The control direction button 16 is 360° direction control, which can effectively control the direction of the wheels 17 .

The wheel 17 in the utility model is also provided with a brake pad, and the brake pad can stabilize the wheelchair.

The lower part of the handrail structure 1 in the utility model is also provided with a card slot, and the card slot is a plurality of reverse concave openings, which can be rotated forward and backward along the steel pipe 4 .

In order to facilitate the understanding of the above-mentioned technical solution of the present utility model, the above-mentioned technical solution of the present utility model will be described in detail below through specific usage modes.

In specific use, when the user needs to lift the seat surface 12, the lifting button 2 can be pushed forward to the upper gear. At this time, the motor 6 in the lifting structure 5 drives the ball 10 on the screw rod 9 to rise, because the ball 10 The seat surface 12 is fixed with the seat rod 11, so when the ball 10 in the lifting structure 5 rises, the seat surface 12 is also rising at this time; the user can easily get the items he needs; when the user needs When the seat surface 12 is lowered, the lifting button 2 is dialed back to the lower gear. At this time, the motor 6 in the lifting mechanism 5 drives the ball 10 on the screw rod 9 to descend. Similarly, the seat surface 12 also descends with the ball 10. ; Complete the rise and fall of the entire device. The utility model can also effectively control the running of the wheels by setting 360° control direction buttons on the armrest, so that when the old man is tired of controlling the wheels with his legs, he can use the control buttons to control the wheels, thereby controlling the entire wheel The direction of the armrest structure 1 in the utility model can be rotated forward and backward through the setting of the card slot. If it is rotated backward, it becomes a backrest; if the armrest structure is rotated forward, when the user slides, it can increase its Stability and safety; when the user does not want to move and has any movement, he can step on the brake pads 17 on the three wheels, so that the wheels 15 are fixed, thereby ensuring the stability of the whole device.

Although the utility model has been disclosed with preferred embodiments, it is not intended to limit the utility model. Any person familiar with this technology can make various changes and modifications without departing from the spirit and scope of the utility model , so the scope of protection of the present utility model should be defined by the claims as the criterion.
