Embodiment 1

[0066] Such as Figure 1-12 As shown, this embodiment proposes an adaptive seat, including a support seat 2 and a seat 1, the seat 1 includes a seat surface 13, the support seat 2 is used for the overall support work of the seat, and the seat surface 13 is used for using hip support for the patient. Also includes:

[0067] An adjustable support assembly 3, the support base 2 is rotationally connected with the adjustable support assembly 3, when the adjustable support assembly 3 rotates around the support base 2, the seat surface 13 of the seat 1 is always kept parallel;

[0068] An angle adjustment mechanism, the angle adjustment mechanism is used to adjust the angle of the seat 1, so that the seat surface 13 of the seat 1 is always kept parallel;

[0069] a rotating mechanism, the rotating mechanism is used to drive the seat 1 to rotate;

[0070] The adjustable support assembly 3 is connected with the rotation mechanism, and the rotation mechanism is connected with the sea...

Embodiment 2

[0092] Such as Figure 1-12 As shown, this embodiment proposes a crawler-type support chassis, including the self-adaptive seat described in Embodiment 1, and the running mechanism includes a front crawler assembly and a rear crawler assembly, and the front crawler assembly and the rear crawler assembly respectively pass through the front turret 51 and the rear turret 41 are hinged with the support base 2. The front track assembly includes a front track segment 52 and a rear track segment 52. A first included angle is formed between the rear track segment 52 and the front track segment 52, and the first included angle is an obtuse angle. .

[0093] It also includes: a rotating shaft 9, the rotating shaft 9 is arranged at the rear end of the front crawler assembly or close to the rear end, and at the same time the rotating shaft 6 is arranged at the front end of the rear crawler assembly or near the front section;

[0094] The front crawler assembly and / or the rear crawler ass...

Embodiment 3

[0110] Such as Figure 1-12 As shown, the present embodiment proposes an all-terrain wheelchair, including the above-mentioned self-adaptive seat, and the front track wheels 54 and the rear track wheels 42 are respectively connected with independent driving mechanisms or the same driving mechanism drives the front track wheels 54 And rear track wheel 42 rotates.

[0111] When using an independent drive mechanism, the drive mechanism drives the front crawler belt 5 and the rear crawler belt 4 to rotate respectively.

[0112] When the same driving mechanism is used, the driving mechanism is a driving motor 43, and there are two driving motors 43, which are fixedly connected with two rear crawler brackets 44 respectively.

[0113] Rotating shaft 6 fixed cover is provided with rear crawler wheel 42 and front crawler wheel 54, and rotating shaft 6 runs through rear crawler support 44 and front crawler support 56, and rear crawler support 44 and front crawler support 56 are all rot...

Abstract

The invention discloses a self-adaptive seat, an all-terrain wheelchair and a self-adaptive climbing method. The self-adaptive seat comprises a supporting seat and a seat body, and the seat body comprises a seat face; the self-adaptive seat further comprises an adjustable supporting assembly, an angle adjusting mechanism and a rotating mechanism; the supporting seat is rotationally connected with the adjustable supporting assembly, and when the adjustable supporting assembly rotates around the supporting seat, the seat face of the seat body is kept parallel all the time; the angle adjusting mechanism is used for adjusting the angle of the seat body, so that the seat face of the seat body is always kept parallel; the rotating mechanism is used for driving the seat body to rotate; the adjustable supporting assembly is connected with the rotating mechanism, and the rotating mechanism is connected with the seat body through the angle adjusting mechanism; and the supporting seat is further connected with a walking mechanism. The wheelchair can walk in all terrains, the seat face of the wheelchair is always parallel to the ground in the stair climbing process, the gravity center of the wheelchair is pressed on the front section of the wheelchair in the stair climbing process, the overall stability is better, the situation that the wheelchair turns over and the like is effectively prevented, and the safety coefficient is high.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to an adaptive seat, an all-terrain wheelchair and an adaptive climbing method. Background technique [0002] Wheelchairs are an indispensable means of transportation for the elderly, the infirm, and those with lower limb disabilities. With the increase of barrier-free facilities, the range of activities of wheelchair users has gradually increased, but stairs and some steep slopes have greatly affected wheelchairs. big limit. According to its transmission mode, wheelchairs can be divided into three types: star wheel type, crawler type and step support type. [0003] The stair-climbing mechanism of the star-wheeled wheelchair is composed of several small wheels evenly distributed on the "Y", "five-star" or "ten"-shaped tie rods. Each small wheel can rotate around its own axis, and can revolve around the central axis together with the tie rod. When walking on flat ground, each ...
