[0029] Figure 1 This is a schematic diagram of the structure of a walking aid provided by an embodiment of the present invention. Figure 1 As shown, in one embodiment of the present invention, the walker includes: an armrest frame 1, a support assembly, a base plate 6, a drive motor 8, a drive wheel 9 and a power-assist control switch, wherein the armrest frame 1 is arranged at the upper part of the support assembly, the base plate 6 is arranged at the lower part of the support assembly, the drive wheel 9 is located on both sides of the base plate 6, the drive motor 8 is arranged on the base plate 6 and is electrically connected to the drive wheel 9 and the power-assist control switch, wherein the power-assist control switch is located on the armrest frame 1 and controls the start and stop of the drive motor 8.

[0030] Specifically, the armrest frame 1, the supporting assembly, the base plate 6, the driving motor 8 and the driving wheel 9 constitute the main structure of the walker. The power-assisting control switch is arranged on the armrest frame 1 to control the start and stop and the speed of the driving motor 8. The driving motor 8 drives the driving wheel 9 to rotate.

[0031] Furthermore, the power-assisted control switch includes a forward gear, a reverse gear, and three speed gears: high speed, medium speed, and low speed. In one embodiment of the present invention, the handrail frame 1 can be made of a variety of materials, and optionally, a stainless steel pipe.

[0032] The walker provided in the embodiment of the present invention is applicable to various working conditions by quickly switching between assisted and unassisted modes. In the assisted mode, it can assist the elderly to walk, and the operation is simple, safe and reliable.

[0033] Reference Figure 1 In one embodiment of the present invention, the support assembly includes two support rods 13, a shock-absorbing buffer spring 4 and a base 5, wherein the first ends of the two support rods 13 are connected to the handrail frame 1, the second ends are connected to the first ends of the shock-absorbing buffer spring 4, the second ends of the shock-absorbing buffer spring 4 are connected to the base 5, and the base 5 is connected to the bottom plate 6.

[0034] Specifically, in one embodiment of the present invention, the second end of the support rod 13 is connected to the first end of the shock-absorbing buffer spring 4 by welding.

[0035] In one embodiment of the present invention, the second end of the shock-absorbing buffer spring 4 is connected to the base 5 in a hinged manner.

[0036] In one embodiment of the present invention, the base 5 and the bottom plate 6 are fixed by bolts.

[0037] The walker provided in the embodiment of the present invention has a shock-absorbing and buffering spring 4 arranged between the handrail frame 1 and the base plate 6, which not only has the function of shock-absorbing and buffering, but also the shock-absorbing and buffering spring 4 is a flexible connection as a connecting piece, which facilitates the handrail frame 1 to produce various angle changes relative to the base plate 6 during the user's walking, thereby improving the flexibility of the walker when adjusting the direction.

[0038] In one embodiment of the present invention, the posture sensing module 3 is located on the support assembly, and is used to sense the angle change of the support assembly relative to the base plate 6 in real time. The control module 2 is located on the armrest frame 1 and is electrically connected to the drive motor 8, and is used to control the moving direction of the walker according to the angle change of the support assembly relative to the base plate 6 in the lateral direction sensed by the posture sensing module 3; and to control the rotation speed of the drive motor 8 according to the angle change of the support assembly relative to the base plate 6 in the traveling direction sensed by the posture sensing module 3, thereby controlling the moving speed of the walker.

[0039] Specifically, the posture sensor module 3 is located on the support rod 13. The control module 2 is provided with a manual working mode, an automatic working mode and a power-assistance control switch, and the power-assistance control switch includes a forward gear, a reverse gear, and three speed gears of high speed, medium speed and low speed.

[0040] When the user needs to turn on the power-assist mode, the user can select the manual working mode or the automatic working mode of the walker according to his own conditions. When the user selects the manual working mode, the user can adjust the moving speed of the walker through the high speed, medium speed and low speed in the power-assist control switch. At this time, the control module 2 controls the drive motor 8 to adjust the speed according to the speed range corresponding to the high speed, medium speed and low speed preset in the power-assist control switch.

[0041] When the user selects the automatic working mode, the walker will automatically adjust the moving speed of the walker according to the user's walking speed.

[0042] Specifically, when the user selects the automatic working mode, the user first needs to select the forward gear or the reverse gear of the power-assistance control switch set on the control module 2, and then the walker starts to start. During the movement of the walker, as the armrest 1 moves, the support rod 13 changes the angle with the base plate 6, specifically the lateral angle change and the angle change in the direction of travel. The posture sensor module 3 transmits the sensed lateral angle change information to the control module 2, and the control module 2 adjusts the moving direction of the walker according to the preset rules. The posture sensor module 3 transmits the sensed lateral angle change information to the control module 2, and the control module 2 adjusts the moving direction of the walker according to the preset rules.

[0043] Furthermore, when the user's moving speed matches the moving speed of the walker, the angle between the two support rods 13 and the base plate 6 is 90°. When the user is moving forward, if the angle between the two support rods 13 and the base plate 6 is greater than 90°, the front end of the handrail frame 1 is close to the front end of the base plate 6, indicating that the user's walking speed is greater than the moving speed of the walker itself. At this time, the control module 2 adjusts the speed of the drive motor 8 according to the result output by the posture sensor module 3 to speed up the moving speed of the walker. If the angle between the two support rods 13 and the base plate 6 is less than 90°, the front end of the handrail frame 1 is away from the front end of the base plate 6, indicating that the user's walking speed is less than the moving speed of the walker itself. At this time, the control module 2 adjusts the speed of the drive motor 8 according to the result output by the posture sensor module 3 to slow down the moving speed of the walker.

[0044] The walker provided in the embodiment of the present invention can automatically adjust the moving speed of the walker according to the walking speed of the user by setting a control module 2 and a posture sensing module 3 on the walker, thereby realizing intelligent control of the walker speed under different walking states, providing a guarantee for the user's safe walking, and having good applicability.

[0045] Continue to refer to Figure 1 In one embodiment of the present invention, the anti-collision sensor modules 7 are located at the four corners of the base plate 6 to sense the presence of obstacles around the walker.

[0046] Specifically, when the user selects the automatic working mode, the user first needs to select the forward gear or the reverse gear of the power control switch set on the control module 2, and then the walker starts. During the movement of the walker, when the anti-collision sensor module 7 receives an anti-collision signal, that is, when it senses that the distance between the surrounding obstacles and the anti-collision sensor module 7 is less than the preset distance, the control module 2 controls the walker to stop moving.

[0047] Continue to refer to Figure 1 In one embodiment of the present invention, the anti-fall strap 12 is arranged on the handrail frame 1. Specifically, when the user uses the walker, the anti-fall strap 12 can be tied on the body to prevent the user from falling during walking.

[0048] The walker provided in the embodiment of the present invention has the functions of anti-collision and anti-fall by providing the anti-collision sensor module 7 and the anti-fall strap 12, thereby providing a guarantee for the user's safe travel and increasing the practicality and reliability of the walker.

[0049] Continue to refer to Figure 1 In one embodiment of the present invention, the battery 10 is located on the bottom plate 6 and is used to power the walker, and the universal wheel 11 is located on the bottom surface of the bottom plate 6 to facilitate the movement of the walker.

[0050] Figure 2 The working principle diagram of the walking aid provided by the embodiment of the present invention is shown in FIG. Figure 2 As shown, the walker has two working modes, manual working mode and automatic working mode. When the user selects the manual working mode, the user can adjust the speed of the walker in stages according to his / her walking speed through the power control switch on the control module 2. In this mode, the anti-collision sensor module 7 is in an inactive state.

[0051] When the user selects the automatic working mode, the user first needs to select the forward gear or the reverse gear of the power control switch set on the control module 2, and then the walker starts. During the movement of the walker, when the anti-collision sensor module 7 receives an anti-collision signal, that is, when it senses that the distance between the surrounding obstacles and the anti-collision sensor module 7 is less than the preset distance, the control module 2 controls the walker to stop moving. When the anti-collision sensor module 7 does not receive an anti-collision signal, the posture sensor module 3 outputs the sensed angle change between the support rod 13 and the base plate 6, and the control module 2 adjusts the speed of the drive motor 8 according to the output result, thereby controlling the moving speed of the walker.

[0052] Specifically, when the user's moving speed matches the moving speed of the walker, the angle between the support rod 13 and the base plate 6 is 90°. When the user is moving forward, if the angle between the two support rods 13 and the base plate 6 is greater than 90°, the front end of the handrail frame 1 is close to the front end of the base plate 6, indicating that the user's walking speed is greater than the moving speed of the walker itself. At this time, the control module 2 adjusts the speed of the drive motor 8 according to the result output by the posture sensor module 3 to speed up the moving speed of the walker. If the angle between the two support rods 13 and the base plate 6 is less than 90°, the front end of the handrail frame 1 is away from the front end of the base plate 6, indicating that the user's walking speed is less than the moving speed of the walker itself. At this time, the control module 2 adjusts the speed of the drive motor 8 according to the result output by the posture sensor module 3 to slow down the moving speed of the walker.

[0053] Now let's take specific examples to explain in detail the working principle of the walker.

[0054] First, when using, the user first puts the anti-fall strap 12 on the body. Then, the user selects the manual working mode or the automatic working mode according to his own conditions.

[0055] When the user selects the manual working mode, the user can select the moving speed of the walker according to his / her own walking speed through the power-assistance control switch on the control module 2. In this mode, the anti-collision sensor module 7 is in an inactive state.

[0056] When the user selects the automatic working mode, the user first needs to select the forward gear or the reverse gear of the power control switch set on the control module 2, and the walker starts to start. As the handrail 1 moves, the angle between the support rod 13 and the base plate 6 changes, specifically the lateral angle change and the angle change in the direction of travel. The posture sensor module 3 transmits the sensed lateral angle change information to the control module 2, and the control module 2 adjusts the moving direction of the walker according to the preset rules.

[0057] During the movement of the walker, when the anti-collision sensor module 7 receives an anti-collision signal, that is, when it senses that the distance between the surrounding obstacles and the anti-collision sensor module 7 is less than a preset distance, the control module 2 controls the walker to stop moving.

[0058] When the anti-collision sensor module 7 does not receive the anti-collision signal, the posture sensor module 3 outputs the sensed angle change between the support rod 13 and the base plate 6, and the control module 2 adjusts the speed of the drive motor 8 according to the output result, thereby controlling the moving speed of the walker.

[0059] Specifically, when the user's moving speed matches the moving speed of the walker, the angle between the support rod 13 and the base plate 6 is 90°. When the user is moving forward, if the angle between the two support rods 13 and the base plate 6 is greater than 90°, the front end of the handrail frame 1 is close to the front end of the base plate 6, indicating that the user's walking speed is greater than the moving speed of the walker itself. At this time, the control module 2 adjusts the speed of the drive motor 8 according to the result output by the posture sensor module 3 to speed up the moving speed of the walker. If the angle between the two support rods 13 and the base plate 6 is less than 90°, the front end of the handrail frame 1 is away from the front end of the base plate 6, indicating that the user's walking speed is less than the moving speed of the walker itself. At this time, the control module 2 adjusts the speed of the drive motor 8 according to the result output by the posture sensor module 3 to slow down the moving speed of the walker.
