[0032] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.
[0033] Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0036] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0037] Embodiment 1. In this embodiment, a walking aid is proposed, as Figure 1 shown, which includes a walking aid frame 1. A universal wheel 2 is rotatably connected to the bottom end of the walking aid frame 1. Two mutually parallel support handrail rods 3 are fixedly installed in the middle of the walking aid frame 1. An old person holds both hands on the support handrail rods 3, and the support handrail rods 3 provide support for the old person. The universal wheel 2 rolls on the ground. A storage bag 4 is fixedly installed in the middle of the upper support handrail rod 3. The side of the storage bag 4 abuts against the middle of the lower support handrail rod 3 to prevent the storage bag 4 from hitting the old person's legs after items are placed in the storage bag 4. A zipper is slidably connected to the top of the storage bag 4. A GPS positioning device is provided on the walking aid frame 1 to determine the position of the device using satellite signals.
[0038] Based on the received satellite signals, the GPS device calculates its precise position in the Earth coordinate system, including longitude, latitude, and altitude, according to the principle of triangulation. The device continuously updates the position data at regular time intervals (such as once per second) to generate continuous position records.
[0039] From the continuous position records, two adjacent position points are sequentially selected. These points represent the positions at different moments during the movement. A specific geographical distance calculation formula, such as the Haversine formula, is used to accurately calculate the actual ground distance between two adjacent position points. This formula fully considers the Earth's curvature to ensure that the calculation result is close to the true value. According to the user's basic information (such as height, gender, etc.), combined with an empirical formula, an initial step length value is set for the user.
[0040] The moving distance between the calculated adjacent position points is divided by the currently estimated step length to obtain the number of steps for a single calculation. The number of steps obtained from multiple calculations is accumulated to obtain the total number of steps of the movement. As the movement continues, the accumulated number of steps is continuously updated to reflect the total amount of the user's movement.
[0041] By receiving signals from multiple satellites, the precise coordinates of the device on the earth are calculated, and then the walking trajectory and distance are calculated based on the changes in coordinates at different time points. This can not only locate the elderly and prevent them from getting lost, but also calculate the distance they have walked to avoid walking too much and becoming overly tired.
[0042] like Figures 2 - 5 As shown, a rear fence member 5 is provided in the middle of the walker frame 1, and the rear fence member 5 includes a one-way rotating member, a rear railing 56, a supporting railing 57, a protective bag cloth 58 and a buckle block 59. A one-way rotating member is provided in the middle of the disc 51, and the one-way rotating member includes a disc 51, a receiving groove 52, a tooth block 53, an avoidance spring 54 and an inner gear ring 55. The disc 51 is fixedly installed in the middle of the walker frame 1, and a receiving groove 52 is provided on the arc surface of the disc 51. The tooth block 53 is rotatably connected in the storage groove 52, and the side of the tooth block 53 is elastically connected to the disc 51 to avoid the spring 54, the inner ring of the avoidance spring 54 is rotatably connected to the disc 51, the tooth block 53 is engaged with the inner gear ring 55, and the rear railing 56 rotates unidirectionally into the fence, and the bottom of the rear railing 56 is fixedly installed with a supporting railing 57. The rear railing 56, the supporting railing 57, the supporting handrail rod 3 and the walker frame 1 form a fence structure, and the elderly stand in the fence.
[0043] When an elderly person stands inside the fence and falls in the bathroom, the fence can prevent him from coming into contact with objects in the bathroom and causing collisions, thus reducing direct injuries.
[0044] The top of the support rail 57 is snapped with a buckle block 59. The support rail 57 adopts an L-shaped structure. Two rear rails 56 and two support rails 57 are provided. The buckle block 59 adopts an inverted U-shaped structure. The buckle block 59 is buckled to the top of the two support rails 57. The side of the buckle block 59 is fixedly installed with a protective bag 58 located between the legs of the elderly. The buckle block 59 buckles the two support rails 57 so that the support rails 57 cannot rotate, so that the fence remains stable. After the buckle block 59 is buckled on the support rail 57, the protective bag 58 is located between the legs of the elderly. When the elderly fall, the protective bag 58 protects the elderly from falling directly to the ground.
[0045] One of the two support rails 57 has a docking block 510 fixedly installed at its end, and the other support rail 57 has a docking groove on its side, into which the docking block 510 is embedded, connecting the two support rails 57 together to improve stability and support effect.
[0046] An extension assembly 6 is provided in the middle of the support handrail bar 3, and the extension assembly 6 includes a storage plate 61 and a reel 62. The storage plate 61 is fixedly mounted in the middle of the support handrail bar 3, and the interior of the storage plate 61 is rotatably connected to the reel 62, and the reel 62 reels the protective bag cloth 58. When the protective bag cloth 58 is not in use, the reel 62 reels the protective bag cloth 58 into the storage plate 61.
[0047] In this embodiment, through the one-way rotation design of the rear railing 56, the elderly person cannot directly open the rear railing 56 outward after falling in the bathroom. The rear railing 56, the supporting railing 57, the supporting handrail rod 3 and the walker frame 1 form a fence structure to prevent the elderly person from contacting and colliding with objects in the bathroom and reducing direct injuries. After the buckle block 59 is buckled on the supporting railing 57, the protective bag cloth 58 is located between the legs of the elderly person, and the protective bag cloth 58 protects the elderly person from falling directly to the ground.
[0048] Embodiment 2, based on embodiment 1, this embodiment proposes a walking aid, such as Figures 5 - 7 As shown, the extension assembly 6 also includes a support block 63, a slider 64 and a friction block 65. The support block 63 is fixedly installed inside the storage plate 61. The side of the support block 63 is slidably connected to the slider 64. The friction block 65 is fixedly installed on the side of the slider 64 facing the winding shaft 62.
[0049] The friction block 65 applies resistance to the reel 62. When the reel 62 rotates, the friction block 65 hinders the rotation of the reel 62. The resistance of the friction block 65 is used to slow down the extension speed of the protective bag cloth 58 to provide buffering protection. Since the reel 62 reels the protective bag cloth 58 to make it a non-rigid connection, the rigidly connected protective bag cloth 58 can avoid hurting the elderly.
[0050] A torque spring is elastically connected between the end of the winding shaft 62 and the storage plate 61 , and the middle portion of the winding shaft 62 is rotatably connected to the support block 63 , so that the winding shaft 62 is reset and the protective bag cloth 58 is rolled up by the torque spring.
[0051] In this embodiment, after the elderly falls, the protective bag cloth 58 protects the elderly and prevents them from falling directly to the ground. At the same time, the protective bag cloth 58 is pulled out, and the reel 62 continuously rotates and rubs against the friction block 65. The resistance of the friction block 65 slows down the extension speed of the protective bag cloth 58 to provide buffering protection and prevent the rigidly connected protective bag cloth 58 from hurting the elderly.
[0052] Example 3
[0053] Based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a walking aid, such as Figures 6 - 8As shown, a friction increasing assembly 7 is provided inside the storage plate 61 and at the end of the winding shaft 62. The friction increasing assembly 7 includes a guide bar 71, a threaded sleeve 72, a threaded block 73, a hydraulic component, and a hydraulic telescopic rod 79. A guide bar 71 parallel to it is fixedly installed on the arc surface of the winding shaft 62. The middle part of the guide bar 71 is slidably connected to the threaded sleeve 72. The threaded block 73 is fixedly installed on the side of the support block 63. The threaded sleeve 72 is threadedly connected to the threaded block 73. The hydraulic component is arranged inside the support block 63.
[0054] The hydraulic component includes a push rod 74, a ball 75, a hydraulic oil pipe 76, a hydraulic piston 77, and a return spring 78. The hydraulic oil pipe 76 is fixedly installed inside the support block 63. The hydraulic piston 77 is slidably connected inside the hydraulic oil pipe 76. The push rod 74 is fixedly installed at the center of the hydraulic piston 77. The push rod 74 extends from inside the support block 63. The end of the push rod 74 is in rolling connection with the ball 75. The ball 75 contacts the end of the threaded sleeve 72. The hydraulic component is communicated with the hydraulic telescopic rod 79 through a hose. The end of the hydraulic telescopic rod 79 is fixedly connected to the storage plate 61. The bottom of the hydraulic telescopic rod 79 is fixedly connected to the slider 64. The hydraulic oil pipe 76 is communicated with the hydraulic telescopic rod 79 through a hose.
[0055] When the winding shaft 62 rotates and drives the threaded sleeve 72 to rotate by means of the guide bar 71, the threaded sleeve 72 and the threaded block 73 cooperate, so that the threaded sleeve 72 moves towards the hydraulic component, thereby causing the threaded sleeve 72 to squeeze the push rod 74. The push rod 74 drives the hydraulic piston 77 to push the hydraulic oil in the hydraulic oil pipe 76 into the hydraulic telescopic rod 79. The hydraulic telescopic rod 79 extends to increase the friction force between the friction block 65 and the winding shaft 62. The more turns the winding shaft 62 rotates, the greater the friction force between the friction block 65 and the winding shaft 62. As the protective drape 58 extends, the friction force between the friction block 65 and the winding shaft 62 increases for buffer protection.
[0056] The side of the hydraulic piston 77 is elastically connected to the hydraulic oil pipe 76 by a return spring 78. The return spring 78 and the push rod 74 are on the same side of the hydraulic piston 77. The hydraulic piston 77 is reset by the return spring 78. Since the threaded sleeve 72 rotates and moves, the ball 75 is used as an intermediate member to replace the direct contact of the push rod 74. When the threaded sleeve 72 rotates, the ball 75 rolls.
[0057] In this embodiment, when the elderly person falls and pulls out the protective cloth 58, the winding shaft 62 rotates and causes the threaded sleeve 72 to rotate. The threaded sleeve 72 cooperates with the threaded block 73, so that the threaded sleeve 72 presses the push rod 74, and the hydraulic telescopic rod 79 extends to increase the friction force between the friction block 65 and the winding shaft 62. As the protective cloth 58 is pulled out, the friction force between the friction block 65 and the winding shaft 62 increases, preventing the protective cloth 58 from being suddenly stopped after being quickly pulled to the limit position and causing breakage.
[0058] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
