Description

Technical Field

[0001] This application relates to the field of mobile assistive device technology, and in particular to a telescopic pole and mobile assistive device. Background Technology

[0002] Assistive mobility devices include walkers and wheelchairs. These devices are designed to assist users in moving around; specifically, they provide support for individuals who cannot walk independently and help them move.

[0003] When traversing a slope, the mobile assistive device will tilt along with the slope, causing the user's body, which is supported by the device, to also tilt. Since users generally have weaker coordination and control abilities than the average person, they are very prone to falls and other accidents once their body tilts to a certain extent. Utility Model Content

[0004] The purpose of this application is to overcome the deficiencies of the prior art and provide a telescopic pole and a mobile auxiliary device to solve the problems in the prior art.

[0005] To address the aforementioned problems, a first aspect of this application provides a telescopic pole for a mobile assistive device, applied to the mobile assistive device, characterized in that it comprises:

[0006] The first component is connected to the walking unit of the mobile auxiliary device;

[0007] The second component is connected to the main body of the mobile assistive device; wherein the main body includes a support member for supporting the user;

[0008] A detection module is used to detect the posture of the support component;

[0009] A drive module is electrically connected to the detection module; wherein the drive module is used to drive the second component to move linearly relative to the first component, adjust the length of the telescopic rod and keep the support member in a preset posture to maintain the user's body balance.

[0010] In one possible implementation, the interiors of both the first component and the second component are hollow structures.

[0011] The first component and the second component are slidably connected; wherein, the slidable direction of the second component relative to the first component corresponds to the length direction of the telescopic rod.

[0012] The drive module includes a linear motion unit, wherein the linear motion unit is used to output linear motion; the drive module is fixed inside the first component, the linear motion unit is inserted into the second component, and the linear motion unit is fixedly connected to the second component.

[0013] In one possible implementation, the second component includes a connecting portion disposed inside the second component, wherein the linear motion portion is fixedly connected to the connecting portion.

[0014] In one possible implementation, the second component is sleeved on the first component, and the second component and the first component are slidably connected.

[0015] In one possible implementation, the drive module includes an electric actuator or a cylinder.

[0016] In one possible implementation, the support includes a seat and / or a support armrest.

[0017] In one possible implementation, the detection module includes an attitude sensor.

[0018] In one possible implementation, when the support member is in the preset posture, the tilt angle of the support member relative to the horizontal plane is a preset angle; wherein, the preset angle is α, 0°≤α≤β, 0°<β≤5°.

[0019] A second aspect of this application provides a mobile assistive device, including a main body, a walking part, and a telescopic rod as described above, wherein the two ends of the telescopic rod are respectively connected to the main body and the walking part.

[0020] In one possible implementation, the walking unit includes a drive wheel, wherein there are two telescopic rods and two drive wheels, and the telescopic rods correspond to the drive wheels.

[0023] During walking, the mobile assistive device's detection module monitors the posture of the main body's support components in real time. The drive module adjusts the length of the telescopic rod to keep the support components in a preset posture, thereby maintaining the user's body balance.

[0024] This telescopic pole can adaptively adjust its length based on the posture of the support member. Thus, even if the road surface tilt changes during movement, the support member can maintain a preset posture, thereby maintaining the user's balance and reducing the probability of falls or other accidents, effectively improving the safety of using the mobile assistance device.

[0040] Example

[0041] See Figure 1 and Figure 2 In this embodiment, a telescopic rod 100 for a mobile assistive device is proposed and applied to the mobile assistive device.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the telescopic pole 100 of the mobile assistance device includes a first component 110, a second component 120, a detection module 130, and a drive module 140. It should be noted that... Figure 3 and Figure 4 The detection module 130 is not shown in the diagram.

[0043] The first component 110 is connected to the walking unit 200 of the mobile auxiliary device.

[0044] The second component 120 is connected to the main body 300 of the mobile auxiliary device. For example... Figure 1 and Figure 2As shown, the main body 300 includes a support member 310 for supporting the user, the support member 310 including a seat 311 and / or a support armrest 312.

[0045] In this embodiment, the support member 310 includes a seat 311 and a support armrest 312. The seat 311 is for users to sit on, and a backrest 320 is provided on the side of the main body 300 near the telescopic rod 100; the support armrest 312 is for users to hold, and when the user is standing, the palm can be held on the support armrest 312, thereby standing or walking with the help of the support armrest 312.

[0046] The detection module 130 is used to detect the attitude of the support member 310. The detection module 130 includes attitude sensors, specifically an IMU (Inertial Measurement Unit). The working principle and structure of the IMU can be found in existing technology and will not be elaborated further here. The attitude sensors include gyroscopes, velocity sensors, and accelerometers. The attitude sensors can detect tilt parameters and travel direction. Based on the tilt parameters, the tilt angle between the support member 310 and the horizontal plane can be obtained (when the tilt angle is zero, it indicates that the support member 310 is in a horizontal state); when the tilt angle is greater than zero, the travel direction can be used to determine whether the mobile auxiliary device is currently in an uphill or downhill state.

[0047] When the mobility assistance device is in use, the posture of both the seat 311 and the support armrest 312 remains consistent. The seat 311 is larger than the support armrest 312. Therefore, a detection module 130 can be installed inside the seat 311. By detecting the posture of the seat 311, the posture of both the seat 311 and the support armrest 312 can be determined simultaneously.

[0048] The drive module 140 is electrically connected to the detection module 130. The drive module 140 is used to drive the second component 120 to move linearly relative to the first component 110, adjust the length of the telescopic rod 100 and keep the support member 310 in a preset posture to maintain the user's body balance.

[0049] In this embodiment, the telescopic rod 100 can adaptively adjust its length based on the posture of the support member 310. Thus, during the movement of the mobile assistance device, even if the inclination angle of the road surface changes, the support member 310 can maintain a preset posture, thereby maintaining the user's balance and reducing the probability of falls or other accidents, effectively improving the safety of using the mobile assistance device.

[0050] When the support member 310 is in a preset posture, the tilt angle of the support member 310 relative to the horizontal plane is a preset angle. The preset angle is α, where 0°≤α≤β, 0°<β≤5°. β can be set as needed, for example, β can be set to 1°, 1.5°, 2°, 3°, 4°, or 5°.

[0051] When the preset angle is set to 0°, it means that the support 310 is in a horizontal state, and at this time, the upper surface of the seat 311 is parallel to the horizontal plane.

[0052] Reference Figure 6 In one embodiment, when the mobile assistance device is located on a horizontal surface, the angle of inclination of the support 310 relative to the horizontal plane is 0°; refer to Figure 7 and Figure 8 When the mobile auxiliary equipment moves onto the slope, if the slope is not greater than the preset angle, the support 310 is in the preset posture regardless of whether the mobile auxiliary equipment is in an uphill or downhill state.

[0053] Continue to refer to Figure 7 When the mobile auxiliary equipment is moving uphill, and the slope is greater than a preset angle, the telescopic rod 100 will extend, thereby adjusting the posture of the support member 310 so that the support member 310 can maintain the preset posture; continue referring to Figure 8 When the mobile auxiliary equipment is going downhill and the slope is greater than the preset angle, the length of the telescopic rod 100 will be shortened, thereby adjusting the posture of the support 310 so that the support 310 can maintain the preset posture.

[0054] In this embodiment, both the first component 110 and the second component 120 have hollow interiors.

[0055] The first component 110 and the second component 120 are slidably connected. The second component 120 can be sleeved on the first component 110, and the second component 120 and the first component 110 are slidably connected.

[0056] The sliding direction of the second component 120 relative to the first component 110 corresponds to the length direction of the telescopic rod 100. Specifically, the sliding direction of the second component 120 relative to the first component 110 is consistent with the length direction of the telescopic rod 100. (Refer to...) Figure 3 The length of the telescopic rod 100 is parallel to the direction of the arrow in the figure.

[0057] like Figure 4 As shown, the drive module 140 includes a linear motion unit 141, which is used to output linear motion. When the drive module 140 is started, the linear motion unit 141 will perform linear motion.

[0058] In this embodiment, the drive module 140 includes an electric actuator or a cylinder. In other embodiments, the drive module 140 may also employ other devices or mechanisms capable of linear motion.

[0059] The drive module 140 is fixed inside the first component 110, and the linear motion unit 141 is inserted into the second component 120, and the linear motion unit 141 is fixedly connected to the second component 120.

[0060] like Figure 9 As shown, the second component 120 includes a connecting part 121, which is disposed inside the second component 120. The linear motion part 141 is fixedly connected to the connecting part 121. The connecting part 121 may be provided with a plate-like structure. The linear motion part 141 and the connecting part 121 can be fixedly connected by means of screws, snap-fit, or other methods.

[0061] Reference Figure 1 and Figure 2 In this embodiment, a mobility assistance device is also proposed, including a main body 300, a walking unit 200, and a telescopic rod 100 of the mobility assistance device mentioned above. The two ends of the telescopic rod 100 are connected to the main body 300 and the walking unit 200, respectively.

[0062] The traveling unit 200 includes two drive wheels, with one telescopic rod 100 and one drive wheel corresponding to each other. The drive wheels are rotatable relative to the telescopic rod 100 and are driven by a motor.

[0063] like Figure 1 and Figure 2 As shown, the mobility aid includes a front leg 400 and a telescopic rod 100. One end of the front leg 400 is rotatably connected to the front wheel 410, and the other end is connected to the main body 300. Compared to the connection part 121 between the front leg 400 and the main body 300, the connection part 121 between the telescopic rod 100 and the main body 300 is closer to the backrest 320.

[0064] The length of the front leg 400 is fixed, while the length of the telescopic rod 100 is adjustable. Thus, when the mobile assistance device moves onto a slope, the support 310 can maintain a preset posture by adjusting the length of the telescopic rod 100, thereby maintaining the user's body balance.

[0065] In this embodiment, there are two telescopic rods 100, and each telescopic rod 100 can extend or retract independently. For example, refer to... Figure 2When the left side of the mobile auxiliary device is lower than the right side, if the support member 310 is not in the preset posture, the length of the left telescopic rod 100 can be extended or the length of the right telescopic rod 100 can be shortened, thereby adjusting the support member 310 to the preset posture.
