[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0017] like Figures 1-5 As shown, an intelligent and safe walking aid for the elderly is provided, including a fixed plate 1. Side plates 2 are fixedly connected to the front and rear surfaces of the fixed plate 1. The opposite sides of the two side plates 2 are symmetrically connected to movable wheels 3 via a rotating shaft. A U-shaped plate 4 is slidably connected to the outer side of the fixed plate 1. Handrails 5 are fixedly connected to both ends of the right side of the U-shaped plate 4. A storage groove 6 is provided on the right side of the fixed plate 1. A rotating rod 7 is provided at the bottom inside the storage groove 6. A seat 8 is fixedly connected to the outer wall of the rotating rod 7. The seat 8 is located inside the storage groove 6. Rotating discs 9 are provided on the front and rear surfaces of the fixed plate 1. The opposite sides of the two rotating discs 9 are fixedly connected to the front end and rear end of the rotating rod 7, respectively. Multiple toothed blocks 10 are fixedly connected to the outer wall of the front rotating disc 9. A transmission gear 36 is rotatably connected to the front surface of the fixed plate 1 and the left side of the rotating disc 9 via a rotating shaft. A motor 11 is fixedly connected to the front surface of the transmission gear 36. The rear surface of the motor 11 is fixedly connected to the front surface of the fixed plate 1. The seat 8 is accommodated in the accommodation groove 6 in the initial state, and bumping caused by the protrusion of the seat 8 can be avoided. When the seat 8 needs to be used, the electric motor one 11 is started, the electric motor one 11 drives the transmission gear 36 to rotate, the transmission gear 36 is engaged with the tooth block 10 on the outer side wall of the front rotating disc 9, and then the rotating disc 9 is driven to rotate, the rotating rod 7 coaxial with the rotating disc 9 is rotated, the seat 8 fixed on the outer side wall of the rotating rod 7 is rotated out of the accommodation groove 6 along with the rotating rod 7, and the seat 8 is unfolded to a horizontal state until the seat 8 is unfolded to a horizontal state. The electric motor one 11 stops working, and the old people can sit on the seat 8 to rest. After the rest is finished, the electric motor one 11 is started again, the electric motor one 11 drives the transmission gear 36 to rotate reversely, the rotating rod 7 is reversely rotated through the engagement transmission of the tooth block 10 and the rotating disc 9, the seat 8 is re-rotated into the accommodation groove 6 along with the rotating rod 7, the electric motor one 11 stops, and the accommodation of the seat 8 is completed. When the old people walk, the handrails 5 are held, and the mobility aid is moved by the moving wheels 3 on the side plates 2.

[0018] As shown in Figure 1 and Figure 2 The upper surface of the fixed plate 1 is fixedly connected with the electric motor two 12 on the left side, the output shaft of the electric motor two 12 is fixedly connected with the belt pulley one 13 at the bottom end, the outer side wall of the fixed plate 1 and located in front of and behind the belt pulley one 13 are rotatably connected with the belt pulley two 14 through the rotating shaft, the outer side wall of the belt pulley one 13 and the outer side wall of the two belt pulley two 14 are commonly connected with the transmission belt 37, the lower surfaces of the two adjustment screw rods 15 are fixedly connected with the limiting circular plate 16 at the bottom end and below the U-shaped plate 4. When the height of the two handrails 5 needs to be adjusted, the electric motor two 12 is started, the output shaft of the electric motor two 12 drives the belt pulley one 13 to rotate, the belt pulley one 13 drives the two belt pulley two 14 to synchronously rotate through the transmission belt 37, and the two belt pulley two 14 drives the adjustment screw rod 15 fixed on the lower surface to synchronously rotate. Since the adjustment screw rod 15 is screw-connected with the U-shaped plate 4, the synchronous rotation of the adjustment screw rod 15 drives the U-shaped plate 4 to move up and down along the outer side of the fixed plate 1, the handrails 5 fixed on the right two ends of the U-shaped plate 4 are synchronously lifted along with the U-shaped plate 4, the simultaneous adjustment of the height of the two handrails 5 is realized, the height consistency is ensured, and the limiting circular plate 16 at the bottom end of the adjustment screw rod 15 can prevent the U-shaped plate 4 from falling off from the adjustment screw rod 15 in the adjustment process. When the handrails 5 are adjusted to the required height, the electric motor two 12 can be turned off, the use of people with different heights can be met, and the practicability and flexibility of the device are improved.

[0019] As shown in Figures 1-3As shown, the front surface and the rear surface of the fixed plate 1 and above the motor one 11 are both provided with a limiting vertical groove 18, the inner upper surface and the inner lower surface of the two limiting vertical grooves 18 are both fixedly connected with a limiting vertical rod 19, the lower side of the outer side wall of the two limiting vertical rods 19 is slidably connected with a sliding block 20, and the opposite sides of the two sliding blocks 20 are both fixedly connected with the inner side wall of the U-shaped plate 4. During the height adjustment of the handrails 5, when the U-shaped plate 4 moves up and down along the outer side of the fixed plate 1, the two sliding blocks 20 will synchronously slide along the limiting vertical rods 19 in the two limiting vertical grooves 18, and the limiting vertical rods 19 constrain the movement track of the sliding blocks 20, avoiding the left-right deviation or shaking of the U-shaped plate 4 during the lifting process. Meanwhile, the upper and lower ends of the limiting vertical grooves 18 can further limit the movement range of the U-shaped plate 4 in cooperation with the limiting circular plate 16, preventing excessive adjustment from causing component damage, so as to ensure that the two handrails 5 always remain stable during the synchronous lifting process, avoiding the influence of unstable adjustment on the safety and comfort of the elderly.

[0020] As shown in Figures 1-3 , the left side of the fixed plate 1 is fixedly connected with a storage frame 17. The storage frame 17 can be directly used to store the water cup, commonly used medicine and folding umbrella required by the elderly during travel, without the need for additional carrying of a backpack, effectively reducing the weight and inconvenience of the elderly during walking, and the storage frame 17 is fixed to the left side of the fixed plate 1, which is reasonable in position and does not occupy the walking space, avoiding the problems of shaking or blocking the line of sight as the traditional walking aid carries an additional backpack, further improving the convenience and safety of the use of the walking aid.

When the motor one 11 drives the rotating rod 7 to rotate the seat 8 to the horizontal state, the two support plates 22 will be in close contact with the corresponding abutting plates 23, at this time, the body weight of the elderly supported by the seat 8 will be transmitted to the abutting plate 23 through the support plate 22, and then dispersed to the whole fixed plate 1 by the limiting cavity 21, instead of being borne by the motor one 11 and the transmission structure only, which greatly improves the support of the seat 8, significantly reduces the bearing pressure of the motor one 11, reduces the loss of the motor under the long-term stress state, effectively prolongs the service life of the motor one 11, ensures the long-term stable operation of the seat 8 storage and expansion function, and further improves the use reliability and durability of the walking aid.

[0022] As shown inFigure 4 As shown, the rear surface of the seat 8 is provided with a soft pad 35; The soft pad 35 can effectively reduce local compression and prevent soreness caused by long-term sitting. At the same time, the soft pad 35 can also increase the friction on the surface of the seat 8 to prevent slipping caused by slight body movement during sitting, further improving the safety of sitting.
