Example Embodiment

[0065] Example one

[0066] like Figure 1-12 As shown, the present embodiment proposes an adaptive seat, including the supporting seat 2 and the seat 1, the seat 1 including a chair surface 13, and the support seat 2 is used for the overall support of the seat, and the chair surface 13 is used for use. Hip support. Also includes:

[0067] The support assembly 3 can be adjusted to the support seat 2 and the adjustable support assembly 3 rotate, and when the adjustable support assembly 3 is rotated about the support seat 2, the seat surface 13 of the seat 1 is always parallel;

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

[0069] Rotating mechanism, rotating mechanism for driving seat 1 rotation;

[0070] The adjustable support assembly 3 is connected to the rotating mechanism, and the rotation mechanism is connected to the seat 1 through the angle adjustm...

Example Embodiment

[0091] Example 2

[0092] like Figure 1-12 As shown, the present embodiment proposes a track-type support chassis including the adaptive seat described in the first embodiment, the traveling mechanism includes a front track assembly and a rear track assembly, a front track assembly, and a rear track assembly respectively through the front rotating frame, respectively. The 51 and the rear rotating frame 41 hinges the support seat 2, the front track assembly includes a front track section 52 and a rear tracking section 52 to form a first incision between the front track 52, and the first angle is an obtuse angle. .

[0093] Also included: the rotating shaft 9, the rotation shaft 9 is disposed at the rear end of the front track assembly or near the rear end, and the rotation shaft 6 is disposed at the front end of the rear track assembly or near the front segment;

[0094] The front track assembly and / or the rear track assembly rotates about the rotating shaft 6, when the rotation ...

Example Embodiment

[0109] Example three

[0110] like Figure 1-12 As shown, the present embodiment proposes a full-stage wheelchair, including the above-described adaptive seat, front track wheel 54, and the rear tracking wheel 42 respectively connected to a separate drive mechanism or the same drive mechanism to drive the front track 54 And the rear track wheel 42 rotates.

[0111] When an independent drive mechanism is used, the drive mechanism drives the front track 5 and the rear track 4 rotation.

[0112] When the same driving drive mechanism is used, the drive mechanism is a drive motor 43, and the drive motor 43 is disposed, and two respectively, respectively, and the two rear track brackets 44 are fixed.

[0113] The rotating shaft 6 fixing the sleeve 42 and the front track 54, the rotation shaft 6 penetrates the rear track bracket 44 and the front track bracket 56, the rear track bracket 44 and the front track bracket 56 rotate the rotation shaft 6. Further, the rotating shaft 6 is adjacent...

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 ...
