Description

Technical Field

[0001] This application relates to the field of rehabilitation equipment technology, and more specifically, to a damping braking device and a walking aid. Background Technology

[0002] Walking aids are assistive mobility tools widely used in rehabilitation medicine, elderly care, and for people with mobility impairments. They are designed to improve user stability, reduce lower limb load, improve balance, and enhance confidence in walking.

[0003] Common mobility aids include walkers and walking bikes, which are usually equipped with two or four directional or omnidirectional wheels, allowing users to push forward to assist walking, or for users to ride and be pushed by others. These are the mainstream devices in the current market.

[0004] However, the equipment not only needs to provide support on flat ground, but also needs to provide reliable speed control and braking safety in complex environments (such as downhill slopes, ramps, uneven roads, and slippery surfaces). Existing walking aids achieve damping function by adjusting the damping on the wheels, thereby achieving the slowing function. However, since the damping adjustment is mostly located at the wheels, it requires bending over to operate, which is very inconvenient. Summary of the Invention

[0005] The purpose of this application is to provide a damping braking device to alleviate the technical problem that the adjustable damping of existing walking aids is set in an off-center position, requiring users to bend over to use it, which is very inconvenient.

[0006] This application provides a damping braking device, including: a drive mechanism, a transmission assembly, and a brake damping mechanism;

[0007] The drive mechanism has a drive end and a moving end, the drive end having at least a first gear, a second gear and a third gear, and the moving end and the drive end being connected in a transmission manner;

[0009] The brake damping mechanism is connected to the other end of the transmission assembly. The brake damping mechanism includes a brake element, a damping element, and a reset element. The brake element and the damping element are arranged sequentially in a direction away from the transmission assembly. The brake element and the damping element move to compress or release the reset element.

[0014] The linkage is located on the fixed part and is rotatably connected to the fixed part. The linkage is connected to the throttle to drive the linkage to rotate. The moving end is located on the linkage.

[0015] Furthermore, in the initial position, the drive end is located within the initial slot;

[0019] When the drive end is in the second gear, the first rotating shaft is located in the second groove;

[0020] When the drive end is in the third gear, the first shaft is located in the third groove.

[0021] Furthermore, a limit switch is provided on the throttle handle;

[0022] The limiting part is located outside the setting space and below the throttle. When the first rotating shaft is located in the third groove, the lower side wall of the limiting part near the fixing member abuts against the outer wall of the fixing member.

[0023] Furthermore, there is a smooth transition between the first groove and the initial groove;

[0024] Limiting protrusions are provided between the initial groove and the second groove, and between the second groove and the third groove. The limiting protrusions can block the first rotating shaft so that the drive end stays in the second or third gear.

[0025] Furthermore, a second rotating shaft is fixedly installed inside the fastener;

[0026] A third pivot is provided between the throttle and the linkage, and the linkage is rotatably connected to the throttle via the third pivot.

[0027] The linkage is rotatably connected to the fixed component via a second rotating shaft;

[0028] The first, second, and third rotating shafts are arranged in parallel.

[0029] Furthermore, the mobile end is located at the end of the linkage that is furthest from the second rotating shaft.

[0030] Furthermore, the mobile terminal is located on the side of the third pivot that is away from the second pivot.

[0031] Furthermore, the brake damping mechanism also includes: a slider;

[0032] The slider is connected to the transmission assembly, and the brake and damping components are both located on the slider.

[0033] Furthermore, the brake damping mechanism also includes: a swing assembly;

[0034] One end of the swing assembly is a rotating end and is mounted on the slider. The damping component is a damping wheel, which is located at the swing end of the swing assembly.

[0035] Furthermore, the oscillating assembly includes: a mounting shaft, a mounting bracket, and a resilient buffer;

[0036] The mounting shaft is located on the slider and extends horizontally;

[0037] One end of the mounting bracket is located on the mounting shaft and slides with the mounting shaft. The mounting bracket is rotatably connected to the slider. The damping wheel is located on the mounting bracket.

[0038] The elastic buffer is located on the mounting shaft and its two ends abut against the mounting bracket and the slider, respectively.

[0039] Furthermore, the brake damping mechanism also includes a limiting member, which is disposed on the slider and slides in cooperation with the slider. The sliding direction of the limiting member is the same as the moving direction of the brake and damping components. The limiting member is used to connect to the vehicle body.

[0040] The transmission assembly includes a transmission wire and a limiting sleeve. One end of the transmission wire is connected to the moving end, and the other end is connected to the limiting component. The limiting sleeve is sleeved outside the transmission wire, and one end of the limiting sleeve abuts against the moving end, while the other end abuts against the slider.

[0041] Furthermore, the brake damping mechanism also includes a locating pin;

[0042] The locating pin is inserted into the slider;

[0043] The reset component is made of elastic material, and its two ends abut against the positioning pin and the limiting component, respectively.

[0044] The purpose of this application is also to provide a walking aid device, including a damping brake device.

[0045] Beneficial effects:

[0046] In the damping brake device provided in this application, the position of the brake damping mechanism is adjusted by a drive mechanism driving a transmission assembly. The drive end can be driven by operating the drive mechanism, allowing it to shift from its initial position to the first, second, or third gear, thereby causing the brake damping mechanism to move accordingly. In use, the damping brake device can be installed on the vehicle body, with the brake damping mechanism positioned above the wheel. The drive end is shifted to the first gear to move the brake and damping components, causing them to descend together until the brake contacts the wheel, achieving the braking function. When the drive end is stopped, the brake... The damping element, the drive end, and the brake wheel all return to their initial positions under the action of the reset element. Similarly, by operating the drive mechanism, the drive end can be switched to the second or third gear. When the drive end is switched to the second gear, the damping wheel contacts the wheel while there is a gap between the brake pad and the wheel, thereby achieving wheel damping and deceleration. When the drive end is switched to the third gear, the brake element contacts the wheel to stop the wheel from rotating. Without operating the drive mechanism, the drive end can remain in the second or third gear to achieve the effect of damping and deceleration or parking. Resetting the drive mechanism again will engage the damping and deceleration or parking state.

[0047] This application, through the combined structure of a drive mechanism, a transmission component, and a brake damping mechanism, enables braking, damping deceleration, and parking operations to be performed by operating only the drive mechanism, without the need to bend over to operate during damping deceleration or parking, making it very convenient to use.

[0048] The mobility aid device provided in this application includes a damping brake device, and therefore has the same technical effect as described above, which will not be repeated here. Attached Figure Description

[0072] The present application will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0073] Combination Figures 1 to 5 The damping brake device provided in this embodiment includes a drive mechanism 100, a transmission assembly 200, and a brake damping mechanism 300.

[0074] The drive mechanism 100 has a drive end and a moving end. The drive end has at least a first gear, a second gear, and a third gear. The moving end and the drive end are connected in a transmission manner. One end of the transmission assembly 200 is connected in a transmission manner to the moving end. The brake damping mechanism 300 is connected in a transmission manner to the other end of the transmission assembly 200. The brake damping mechanism 300 includes a brake element, a damping element, and a reset element 301. The brake element and the damping element are arranged sequentially in a direction away from the transmission assembly 200. The brake element and the damping element move to compress or release the reset element 301.

[0075] Furthermore, when the drive end is in the first gear, the brake and damping components move a first distance away from the transmission assembly 200. When the drive end is in the second gear, the brake and damping components move a second distance away from the transmission assembly 200. When the drive end is in the third gear, the brake and damping components move a first distance away from the transmission assembly 200.

[0076] It should be noted that in this embodiment, the second distance is less than the first distance, the drive mechanism 100 is used for manual drive, and the drive end can stop at the second or third gear.

[0077] Combination Figures 6 to 9 During assembly, the slider must be fitted onto the frame above the wheel, ensuring a gap between the damping wheel 320 and the wheel, with the gap not exceeding a second distance. This ensures that the damping wheel 320 can contact the wheel during its downward stroke. Similarly, the straight-line distance between the brake pad 350 and the wheel should not exceed a first distance, thus ensuring that the brake pad 350 can contact the wheel during its downward stroke to achieve braking or parking effects.

[0078] Combination Figure 12 Specifically, the damping brake device provided in this embodiment needs to be installed on the frame of the walking aid or other equipment, and the drive mechanism 100 is installed at the handlebars so that the user can operate the drive mechanism 100 when gripping the handlebars.

[0079] The brake damping mechanism 300 is disposed above the wheel so that the damping element can be located between the brake element and the wheel. The damping element, brake element, transmission assembly 200 and drive mechanism 100 are arranged in sequence in the direction away from the wheel so that when the drive mechanism 100 is operated, the brake element and the damping element can be driven to move closer to the wheel.

[0080] When the drive end is in the second gear, the damping wheel 320 is in contact with the wheel, while the brake pad 350 is spaced apart from the wheel. The damping element is in contact with the wheel, but the brake element is not. When the drive end is in the first and third gears, the movement distance of the brake element and the damping element is larger, so that both the brake element and the damping element are in contact with the wheel, achieving wheel braking. The drive mechanism 100 drives the transmission assembly 200 to adjust the position of the brake damping mechanism 300. The drive end can be driven by operating the drive mechanism 100, so that the drive end can be switched from the initial position to the first gear, second gear, and third gear, thereby driving the brake damping mechanism 300 to move accordingly.

[0081] When the drive end is stopped, if it is in the first gear, the brake, damping, and drive end will all return to their initial positions under the action of the reset member 301. If the drive end is in the second or third gear, it can remain in the second or third gear to achieve the effect of damping deceleration or parking without further operation of the drive mechanism 100. Resetting the drive mechanism 100 will release the damping deceleration or parking state. Since the drive mechanism 100 in this embodiment is located on the handlebars of the vehicle, it can be operated directly by hand. Braking, damping deceleration, and parking can be achieved by operating only the drive mechanism 100, without having to bend over to operate during damping deceleration or parking, making it very convenient to use.

[0082] In this embodiment, the drive mechanism 100 includes a fixing member 110, a throttle 120, and a linkage member 130. The fixing member 110 has a mounting space. The throttle 120 is rotatably connected to the fixing member 110, with one end of the throttle 120 serving as the drive end and located within the mounting space, and the other end extending out of the fixing member 110 for manual operation. The linkage member 130 is located on and rotatably connected to the fixing member 110, and is drively connected to the throttle 120 to drive the linkage member 130 to rotate. A movable end is located on the linkage member 130.

[0083] In this embodiment, the fixing member 110 is used to connect with the vehicle body and frame to form a setting space. The linkage member 130 is set in the setting space of the fixing member 110. An opening is provided on one side of the fixing member 110. The throttle 120 is inserted into the opening. One end of the throttle 120 is rotatably connected to the linkage member 130 to drive the linkage member 130 to rotate. The other end of the throttle 120 protrudes from the opening so that the user can operate the throttle 120 to rotate by pinching or pressing down, thereby driving the moving end on the linkage member 130 to move upward, so that the moving end can drive the brake and damping components to move through the transmission component 200.

[0084] Combination Figure 2 , Figure 11In this embodiment, the drive end of the throttle 120 is provided with a rotating hole 122. An initial groove, a first groove 123, a second groove 124 and a third groove 125 are provided on one side wall of the rotating hole 122.

[0085] In the initial position, the initial groove is located at the top of the rotating hole 122, the first groove 123 is located on one side of the rotating hole 122, and the second groove 124 and the third groove 125 are located on the other side of the rotating hole 122. The heights of the initial groove, the second groove 124, and the third groove 125 decrease sequentially, with the height of the third groove 125 being the same as the height of the first groove 123. A first rotating shaft 111 is fixedly installed inside the fixing member 110 and is inserted into the rotating hole 122. When the drive end is in the first gear position, the first rotating shaft 111 is located in the first groove 123. When the drive end is in the second gear position, the first rotating shaft 111 is located in the second groove 124. When the drive end is in the third gear position, the first rotating shaft 111 is located in the third groove 125.

[0086] Specifically, in this embodiment, the damping braking device is in its initial position when the vehicle is in normal driving. Combined with... Figure 9 At this time, the first rotating shaft 111 is located in the initial groove. Since the first groove 123, the second groove 124, and the third groove 125 are all located below the first groove 123, the first rotating shaft 111 can stably exist in the first groove 123 without external force intervention, so that the wheel and the brake and damping components are in a spaced-out state, avoiding the brake and damping components from contacting the tire and affecting driving.

[0087] When braking is required, the throttle 120 can be rotated so that it rotates around the first shaft 111 until the first shaft 111 enters the first groove 123. (Combined) Figure 6 In this embodiment, the specific action is to raise the throttle 120 to achieve the engagement of the first rotating shaft 111 and the first groove 123. During this process, since the linkage 130 is rotatably connected to the throttle 120, the connection point of the rotating component with the throttle 120 rotates together with the throttle 120, thereby pulling the transmission assembly 200 to drive the brake damping mechanism 300. Under the drive of the transmission assembly 200, the brake component and the damping component move a first distance toward the wheel, so that the brake component contacts the wheel to achieve the braking action.

[0088] It should be noted that, in this embodiment, the linkage 130 is provided with a support 131. When the damping brake device is in the initial state or the first gear, the support 131 abuts against the rotating end of the throttle 120 so that the rotating end of the throttle 120 will not move down when it is lifted, thereby pulling the connection with the linkage 130 upward so that the first rotating shaft 111 can smoothly enter the first groove 123.

[0089] When encountering steep inclines, to prevent excessive vehicle speed, the damping braking device can be switched to a slow-dampening state, i.e., the first shaft 111 enters the second groove 124. Combined with... Figure 7 Specifically, the second groove 124 is located on the side of the initial groove away from the first groove 123. Therefore, in this embodiment, when the first rotating shaft 111 is located in the initial groove, the throttle 120 is rotated by pressing down until the first rotating shaft 111 enters the second groove 124. At this time, the brake and damping components move down a second distance, the damping component contacts the wheel and the brake component does not contact the wheel, and the wheel achieves slow movement under the action of the damping component.

[0090] Furthermore, in this embodiment, when a stop is required, the throttle 120 can be pressed down again under slow-damping conditions, combined with... Figure 8 The throttle 120 is rotated again to disengage the first shaft 111 from the second groove 124 and into the third groove 125. The brake and damping components move down again until the brake contacts the wheel, thus achieving braking. Furthermore, since both sides of the second groove 124 and the third groove 125 have limit mechanisms, when the first shaft 111 is in the second groove 124 or the third groove 125, if no external force is involved (i.e., the user does not operate the throttle 120), the first shaft 111 can remain in the second groove 124 or the third groove 125 for a long time, thereby achieving vehicle slowing and stopping.

[0091] In this embodiment, a limiting part 121 is provided on the throttle 120. The limiting part 121 is located outside the setting space and below the throttle 120. When the first rotating shaft 111 is located in the third groove 125, the lower side wall of the limiting part 121 near the fixing member 110 abuts against the outer wall of the fixing member 110.

[0092] Specifically, in this embodiment, the limiting part 121 is located in the middle section of the throttle 120 and protrudes outward from the throttle 120 and extends downward. When the damping brake device is in the initial state, braking state, or damping state, there is a gap between the limiting part 121 and the fixing member 110. When the throttle 120 is rotated to the point where the first rotating shaft 111 engages with the third groove 125, the limiting part 121 abuts against the side wall of the fixing member 110 located below the opening, thereby limiting the throttle 120 to indicate that the throttle 120 has been rotated to the correct position.

[0093] Please combine Figure 11 Specifically, in this embodiment, there is a smooth transition between the first groove 123 and the initial groove. Limiting protrusions are provided between the initial groove and the second groove 124, and between the second groove 124 and the third groove 125. The limiting protrusions can block the first rotating shaft 111 so that the drive end stays in the second gear or the third gear.

[0094] In this embodiment, both the second groove 124 and the third groove 125 have an arc-shaped structure. The junction between the initial groove and the second groove 124, and the junction between the second groove 124 and the third groove 125, have outward convex structures to form limiting protrusions. With this structure, when the throttle 120 is rotated, the first rotating shaft 111 can smoothly enter the second groove 124 or the third groove 125 along the smooth transition and the arc-shaped structure.

[0095] Furthermore, after the first rotating shaft 111 enters the second groove 124 or the third groove 125, the limiting protrusion can form a limit from both sides to prevent the first rotating shaft 111 from coming out, thereby making the first rotating shaft 111 stably exist in the second groove 124 and the third groove 125.

[0096] In this embodiment, a second rotating shaft 112 is fixedly disposed inside the fixing member 110. A third rotating shaft 126 is disposed between the handle 120 and the linkage member 130, and the linkage member 130 is rotatably connected to the handle 120 through the third rotating shaft 126. The linkage member 130 is rotatably connected to the fixing member 110 through the second rotating shaft 112. The first rotating shaft 111, the second rotating shaft 112, and the third rotating shaft 126 are arranged in parallel.

[0097] Specifically, in this embodiment, the first rotating shaft 111, the second rotating shaft 112 and the third rotating shaft 126 are arranged in parallel, that is, the rotation direction of the handle 120 and the linkage 130 is the same, and when the handle 120 rotates, it drives the linkage 130 to rotate in the same direction.

[0098] In this embodiment, the third rotating shaft 126 is disposed on the throttle 120, and the linkage 130 is provided with a shaft hole to be sleeved onto the third rotating shaft 126 to achieve a rotating connection.

[0099] Furthermore, in this embodiment, the moving end is located at the end of the linkage 130 that is away from the second rotating shaft 112.

[0100] Specifically, in this embodiment, the second rotating shaft 112, the third rotating shaft 126, and the moving end are arranged at intervals along a straight line. The farther the moving end is from the second rotating shaft 112, the longer the stroke of the moving end, that is, the greater the distance that the transmission component 200 can move, thereby ensuring that the moving distance of the brake component and the damping component is sufficient to contact the tire.

[0101] In this embodiment, the mobile end is located on the side of the third rotating shaft 126 away from the second rotating shaft 112.

[0102] In this embodiment, the third rotating shaft 126 and the moving end are arranged sequentially in a direction away from the second rotating shaft 112. The third rotating shaft 126 and the moving end are located on the same side of the second rotating shaft 112, thereby saving the space occupied by the linkage 130 and reducing the volume of the fixing member 110.

[0103] It should be noted that in this embodiment, the linkage 130 is a hollow structure, the second rotating shaft 112 and the moving end are respectively set at both ends of the linkage 130, and the third rotating shaft 126 is set in the middle section of the linkage 130 and close to the moving end. In this embodiment, the moving end is a ring structure so that the transmission component 200 can be connected to the moving end.

[0104] In this embodiment, the brake damping mechanism 300 further includes a slider. The slider is connected to the transmission assembly 200, and both the brake element and the damping element are disposed on the slider.

[0105] In this embodiment, the slider is used to be fitted onto the vehicle body and frame, and the transmission assembly 200 drives the slider to move so as to move the brake and damping components.

[0106] In this embodiment, the brake damping mechanism 300 further includes a swing assembly 310. One end of the swing assembly 310 is a rotating end and is disposed on the slider, and the damping element is a damping wheel 320, which is disposed at the swing end of the swing assembly 310.

[0107] When subjected to force, the swing assembly 310 can swing slightly. The damping wheel 320 is located at the swing end of the swing assembly 310. When the damping wheel 320 contacts the wheel body, the vibration received by the damping wheel 320 can be transmitted to the swing assembly 310. The swing assembly 310 swings to achieve buffering and prevent the damping wheel 320 from being damaged due to excessive vibration.

[0108] In this embodiment, the swing assembly 310 includes a mounting shaft 311, a mounting bracket 312, and an elastic buffer 313. The mounting shaft 311 is disposed on the slider and extends horizontally. One end of the mounting bracket 312 is disposed on the mounting shaft 311 and slides in engagement with the mounting shaft 311. The mounting bracket 312 is rotatably connected to the slider, and a damping wheel 320 is disposed on the mounting bracket 312. The elastic buffer 313 is disposed on the mounting shaft 311 and its two ends abut against the mounting bracket 312 and the slider, respectively.

[0109] In this embodiment, the slider sidewall is provided with a mounting hole with internal threads, and the mounting shaft 311 is threaded through the mounting hole. Specifically, in this embodiment, a limiting block with a large outer diameter is provided at the end of the mounting shaft 311 away from the mounting hole. The mounting bracket 312 is provided with a hole, and the mounting bracket 312 is sleeved on the mounting shaft 311 through the hole and can move along the axial direction of the mounting shaft 311. The limiting block can form a barrier to prevent the mounting bracket 312 from falling off the end of the mounting shaft 311.

[0110] In this embodiment, the elastic buffer 313 is specifically a buffer spring. The buffer spring is sleeved on the mounting shaft 311, and one end of the buffer spring abuts against the side wall of the slider, while the other end abuts against the side wall of the mounting bracket 312.

[0111] In this structure, when the damping wheel 320 contacts the wheel body and is subjected to force, the mounting bracket 312 moves toward the slider along with the damping wheel 320 to buffer the mounting bracket 312 and the damping wheel 320, and to prevent the mounting bracket 312 and the damping wheel 320 from deforming due to excessive force.

[0112] Furthermore, in this embodiment, the hole on the mounting bracket 312 is an elongated hole with the opening extending vertically, and the mounting shaft 311 passes through the hole. When the damping wheel 320 is subjected to force, the mounting bracket 312 can not only move along the axial direction of the mounting shaft 311 to compress the mounting shaft 311, but the mounting bracket 312 can also swing on the mounting shaft 311 by relying on the elongated hole, thereby further improving the damping effect.

[0113] In addition, in this embodiment, the brake damping mechanism 300 also includes a protective shell. One end of the protective shell is connected to the slider and extends horizontally. The protective shell covers the mounting shaft, buffer spring, damping wheel 320 and mounting bracket 312 to form a protective structure.

[0114] In this embodiment, the brake damping mechanism 300 further includes a limiting member 330, which is disposed on the slider and slides in cooperation with the slider. The sliding direction of the limiting member 330 is the same as the moving direction of the brake and damping components. The limiting member 330 is used to connect to the vehicle body. The transmission assembly 200 includes a transmission wire and a limiting sleeve. One end of the transmission wire is connected to the moving end, and the other end is connected to the limiting member 330. The limiting sleeve is sleeved outside the transmission wire, and one end of the limiting sleeve abuts against the moving end, while the other end abuts against the slider.

[0115] Specifically, in this embodiment, the slider has a sliding hole, the extension direction of which is the same as the movement direction of the brake pad 350 and the damping wheel 320, and one end of the limiting member 330 is threaded. When the slider is fitted onto the vehicle body or frame, the limiting member 330 passes through the sliding hole and is connected to the vehicle body or frame through a threaded engagement. With this structure, the slider can slide along the vehicle body or frame and abut against the limiting member 330 when it slides to its limit position, thereby limiting the slider and preventing it from sliding out of the preset path, which would prevent the brake pad 350 or the damping wheel 320 from contacting the wheel under the drive of the transmission assembly 200.

[0116] Furthermore, in this embodiment, the transmission wire is the brake cable, and the limiting sleeve is the brake cable sheath. One end of the brake cable is attached to the annular structure of the moving end, and the other end abuts against the slider.

[0117] The brake cable sheath is located outside the brake cable, with one end abutting the bottom end of the fixing member 110 and the other end abutting the limiting member 330. In this configuration, when the throttle 120 is raised or lowered, the moving end of the linkage 130 swings upward to pull the brake cable upward. At this time, the brake cable sheath is not pulled; instead, it is compressed by the fixing member 110 and moves downward along the brake cable, thereby pressing down the slider and causing it to move downward along the sliding hole, thus moving the damping wheel 320 and the brake pad 350 toward the wheel body.

[0118] In this embodiment, the brake damping mechanism 300 further includes a positioning pin 340. The positioning pin 340 is inserted into the slider. The reset member 301 is made of elastic material, and its two ends abut against the positioning pin 340 and the limiting member 330, respectively.

[0119] Specifically, the positioning pin 340 is inserted into the slider, with its top end located at the bottom end of the sliding hole. In this embodiment, the reset member 301 is a reset spring, with its top end abutting against the bottom end of the positioning pin 340 and its bottom end abutting against the top end of the limiting member 330. In this structure, when the brake cable pushes the slider downwards, the positioning pin 340 moves with the slider and compresses the reset spring together with the limiting member 330.

[0120] When the first shaft 111 is located in the second groove 124 and the third groove 125, the limiting flange can limit the first shaft 111, and the return spring cannot push the brake cable to return to its original position, so that the damping brake device can maintain a slow-dampening state or a parking state. When the first shaft 111 is located in the first groove 123, if the throttle 120 is stopped from being lifted, the throttle 120 loses external force, and there is no limiting structure between the first groove 123 and the initial groove. At this time, the return spring undergoes restorative deformation to push the brake cable to return to its original position, thereby pulling the linkage 130 to return to its original position, and then pulling the throttle 120 to rotate back to its initial position to achieve automatic reset after braking.

[0121] When using the damping braking device provided in this application, the damping wheel 320 will contact the wheel first, whether in a parking or braking state. For elderly people who are weak and unable to exert force, in an emergency, they may not be able to instantly achieve the force required to fully apply the handbrake. However, the initial force is sufficient to make the damping wheel 320 contact the wheel first to decelerate, and then the brake pad 350 will contact the wheel to apply the brakes, thus meeting the elderly person's need for emergency braking.

[0122] The walking aid device provided in this embodiment includes the damping brake device provided in the above embodiment.

[0123] The walking aid includes a frame and wheels, with a handlebar extending horizontally at the top of the frame.

[0124] See Figure 10 The damping brake device mounting bracket 110 is mounted on the frame below the handlebars so that the extension direction of the throttle 120 is the same as the extension direction of the handlebars, making it convenient for the user to lift and press the throttle 120.

[0125] In this embodiment, the slider is mounted on the frame above the wheel, and the gap between the damping wheel 320 and the wheel is no greater than the second distance, so as to ensure that the damping wheel 320 can abut against the wheel when it moves down to the limit position. Similarly, the straight-line distance between the brake pad 350 and the wheel is no greater than the first distance, thereby ensuring that the brake pad 350 can abut against the wheel when it moves down to the limit position to achieve the braking or parking effect.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
