Description of drawings

Figure 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail.

As shown in Figure 1, the auxiliary standing seat includes body parts, wheels and transmission parts.

The body parts include a base plate 1, a back 5, an armrest 6, a rear seat plate 7, a front seat plate 8, an upper cross bar 9, a lower cross bar 10, an intermediate support 14, a front leg 17, a front support 18 and a foot 19.

The wheels include a rear wheel 2, an intermediate wheel 3 and a front wheel 4, wherein the rear wheel 2 is driven by a motor.

The transmission components include a lifting motor 20 , a bottom bar 21 , a seat plate connecting rod 11 , a push rod 13 , a central shaft 12 , a slide rail 15 and a slide block 16 .

Looking at the whole picture, it can be seen that the bottom plate 1 is placed on the bottom of the vehicle body, and the middle bracket 14 is straddled on the bottom plate 1. The rear end of the bottom plate 1 is provided with two larger rear wheels 2. The rear wheels 2 are driven by a motor and can be reversed. Rotate to realize forward and backward movement, the front end of the bottom plate 1 is connected with the front leg, the lower end of the front leg is provided with two middle wheels 3, the back 5 is parallel to the front leg 17, and is hinged with the front leg 17 through the upper cross bar 9 and the lower cross bar 10 Together, they form a parallelogram, or four-bar structure. The middle position of the back 5 is fixed with a handrail 6, and the upper end of the front leg 17 is hinged with a front bracket 18. The lower end of the front bracket 18 is provided with two smaller front wheels 4, and the front bracket 18 rests on the lower cross bar 10 under its own gravity. The front support 18 is also provided with a step 19 . The lifting motor 20 is hinged with the bottom rod 21, both of which are fixed on the base plate 1, and the top of the lifting motor 20 is connected with a push rod 13, and the push rod 13 is hinged with a rear seat plate 7, and the rear seat plate 7 rear end is hinged with the back 5, The front end is hinged with the front seat plate 8 rear end and the seat plate connecting rod 11 front ends. The rear end of the seat plate connecting rod 11 is hinged to a central shaft 12, which is arranged on the middle bracket 14, and the central shaft 12 and the upper end of the front leg 17 are provided with a slide rail 15, and the slide rail 15 is provided with a slide block 16. Block 16 links to each other with the front end of front seat board 8 and can do linear sliding on slide rail 15.

The working principle of the utility model is as follows:

When the patient wants to stand, the lifting motor 20 is driven, the push rod 13 is extended upwards, and the rear seat plate 7 is then lifted upwards, thereby driving the seat plate connecting rod 11 to rotate backward around the central axis 12, and then driving the front seat plate 8 along the slide rail 15 Sliding backward, at the same time, the upper cross bar 9 and the lower cross bar 10 rotate around the hinge points respectively so as to drive the back 5 to move upward in translation. Tilting can assist the patient to stand. At this time, the patient stands on the step 19, supports the handrail 6, and the gravity presses the front bracket 18 to press down, so the front wheel 4, the middle wheel 3 and the rear wheel 2 are supported on the ground at the same time, increasing the The force-bearing area is enlarged to prevent dumping.

When the patient wants to return to the sitting posture, the lifting motor 20 is driven, and the push rod 13 is retracted downward, and all components move in the opposite direction as above, so that the rear seat board 7 and the front seat board 8 are restored to the level, and finally the patient sits firmly, and the front wheels 4 are put away from the ground , the whole vehicle is supported by the rear wheel 2 and the middle wheel 3.

When the patient wants to move the seat, he only needs to operate the motor and the steering gear of the rear wheel 2 to realize.
