[0001] The utility model relates to the field of intelligent walking-replacing robots, in particular to an adjusting device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. It can perform tasks such as work or movement through programming and automatic control. In the field of mobility assistance, in order to make travel more convenient for people with limited mobility, the low-automation properties of traditional mobility tools, such as wheelchairs, are updated to better assist people with limited mobility and better integrate into the lives of users. Embodied intelligent robots are the product of the deep integration of embodied intelligence technology and intelligent mobility tools. It is no longer just a means of transportation, but an "intelligent body" with autonomous perception, cognition, decision-making and action capabilities, which can assist people with limited mobility (such as the elderly and people with disabilities) to move and complete daily tasks in complex environments more safely, naturally and proactively.

[0004] When riding outdoors on uphill or downhill sections, the changing terrain gradient can cause discomfort. Sharp gradients can also cause a shift in the center of gravity, affecting the stability of the intelligent mobility robot. Existing mobility robots, when used at home, need to be placed indoors. Since they cannot be folded, they take up space indoors and are not portable when traveling. Utility Model Content

[0021] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0022] like Figures 1-4 As shown, the utility model is an adjustment device, which is used for an intelligent walking robot. The structure includes a seat 1, a seat back 2 rotatably connected to the seat 1, a pressure sensor, a gyroscope, and an adjustment structure arranged in the seat 1;

[0023] First, the adjustment structure is described, which includes the seat adjustment structure and the seat back adjustment structure:

[0024] The seat adjustment structure includes two quadrilateral connecting rod mechanisms and a first electric push rod 3 connected to the quadrilateral connecting rod mechanism; the quadrilateral connecting rod mechanism includes a connecting seat 4 connected to the bottom of the seat 1, a first connecting beam 5 hinged to the connecting seat 4 at one end, a second connecting beam 6 hinged to the connecting seat 4 at one end, and a clamping seat 7; the first connecting beam 5 is parallel to the second connecting beam 6, and the clamping seat 7 is hinged to the other ends of the first and second connecting beams.

[0025] In order to realize automatic control of the angle adjustment of the seat 1, a connecting rod 8 is provided between the two first connecting beams 5, and a first electric push rod 3 is rotatably connected to the connecting rod 8. The push rod end of the first electric push rod 3 is hinged to the bottom of the seat 1. Figure 5As shown by the red arrow in the middle, when the push rod of the first electric push rod 3 is extended, the first and second connecting beams of the quadrilateral linkage mechanism rotate counterclockwise at the hinge side of the clamping seat 7, and the first electric push rod 3 rotates counterclockwise with the connecting rod as the center of the circle, synchronously driving the seat 1 to rotate counterclockwise while the horizontal height of the seat 1 is raised; when the push rod of the first electric push rod 3 is shortened, the first and second connecting beams rotate clockwise at the hinge side of the clamping seat 7, and the first electric push rod 3 rotates clockwise with the connecting rod as the center of the circle, synchronously driving the horizontal height of the seat 1 to drop, and the seat 1 rotates clockwise. Continuous contraction to the bottom point allows the seat 1 to be folded and stored to the chassis position.

[0026] Seat back adjustment structure:

[0027] The chair back adjustment structure includes a linkage connecting rod structure and a second electric push rod 9 connected to the linkage connecting rod structure; the second electric push rod 9 is hingedly arranged under the seat 1, and the linkage connecting rod structure includes a first linkage member 10 hingedly arranged under the seat 1 and a second linkage member 11 hinged to the first linkage member 10; the push rod end of the second electric push rod 9 is hinged to the first linkage member 10 and the second linkage member 11, and the non-hinged end of the second linkage member 11 is hinged to the chair back 2.

[0028] As the instruction manual Figure 5 As shown by the black arrow in the middle, when the push rod of the second electric push rod 9 extends, it drives the first linkage 10 and the second linkage 11 to rotate counterclockwise. Since the chair back 2 is hinged to the seat 1, the second linkage 11 drives the chair back 2 to rotate relative to the hinge point on the seat 1 in the counterclockwise direction during the rotation process, causing the chair back 2 to move closer to the seat 1. During the extension process of the second electric push rod 9, due to the change in the position of the first linkage 10 and the second linkage 11, the second electric push rod 9 rotates clockwise around its hinge point with the seat. The second electric push rod 9 continues to extend until it can rotate the chair back 2 counterclockwise to the seat 1 position, thereby folding the chair back 2. When the push rod of the second electric push rod 9 retracts, it drives the first linkage 10 to rotate clockwise. At the same time, the second linkage 11 pulls the chair back 2 to rotate clockwise around the hinge point of the seat, causing the chair back 2 to move away from the seat 1. During the retraction process of the second electric push rod 9, the second electric push rod 9 rotates counterclockwise around its hinge point with the seat.

[0029] The data from the pressure sensor and gyroscope are fed back into the control system of the intelligent mobility robot. The data fed back together controls the first electric push rod to adjust the seat angle and the second electric push rod to adjust the backrest angle. To improve vehicle stability when traveling uphill or downhill, the adjustment mechanism needs to adjust the angles of seat 1 and backrest 2 based on data from the gyroscope (seat 1's center of gravity angle position) and the pressure sensor (gravity change). For example, when traveling uphill, the gyroscope detects a 10° offset in the center of gravity angle. To prevent the vehicle from tilting backward and causing the occupant to feel like they're tipping over, thus affecting the user experience, the gyroscope, combined with the pressure sensor data, synchronously rotates seat 1 and backrest 2 counterclockwise by 5° to 10°, thereby moving the center of gravity of the intelligent mobility robot forward. After these adjustments, the backrest 2 supports the occupant's back, giving the occupant a greater sense of security. To prevent tipping over when going uphill due to excessive slope, a pair of anti-roll wheels are provided at the rear of the vehicle.

[0030] When going downhill, the adjustment method is slightly different from that of going uphill. Since the quadrilateral linkage mechanism will also rotate synchronously during the lifting and adjustment process of the seat 1, the horizontal height of the seat 1 will also change. Correspondingly, during the downhill process, the seat 1 needs to be lowered in height to stabilize the center of gravity. Therefore, when going downhill, the seat 1 needs to be rotated counterclockwise (the first electric push rod 3 extends) to lower the horizontal height of the seat 1. At the same time, the seat back 2 needs to be rotated clockwise (the second electric push rod 9 contracts) to adjust the change of the overall center of gravity and reduce the sense of panic when riding.

[0031] In order to facilitate users to adjust the angles of the seat 1 and the seat back 2 according to their own comfort, a button 12 is provided under the seat, and the first electric push rod 3 and the second electric push rod 9 are both controlled to extend by the button.
