Description

Technical Field

[0001] The present application relates to the technical field of rehabilitation equipment, and in particular to a damping brake device and a walking aid device. Background Art

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

[0003] Common walking aids include walkers and strollers, which are usually equipped with two or four directional or universal wheels, allowing users to push them forward to assist walking, or allow users to ride on them and be pushed by others. They are the mainstream devices in the current market.

[0004] However, the device not only needs to provide support on flat surfaces but also needs to provide reliable speed control and braking safety in complex environments, such as downhill slopes, slopes, uneven roads, and slippery surfaces. Existing walkers achieve this function by adjusting the damping force on the wheels, thereby achieving a deceleration function. However, since the damping force is often adjusted on the wheels, it requires bending over to operate, which is very inconvenient. Summary of the Invention

[0009] Furthermore, a limit portion is provided on the turning handle; The limiting portion is located outside the setting space and below the turning handle. When the first rotating shaft is located in the third slot, the side wall of the lower end of the limiting portion close to the fixing member abuts against the outer wall of the fixing member.

[0010] Furthermore, there is a smooth transition between the first slot and the initial slot; A limiting protrusion is provided between the initial groove and the second groove body, and between the second groove body and the third groove body. The limiting protrusion can block the first rotating shaft so that the driving end stays in the second gear position or the third gear position.

[0011] Furthermore, a second rotating shaft is fixedly provided in the fixing member; A third rotating shaft is provided between the turning handle and the linkage member, and the linkage member is rotatably connected to the turning handle via the third rotating shaft; The linkage member is rotatably connected to the fixed member via a second rotating shaft; The first rotating shaft, the second rotating shaft and the third rotating shaft are arranged in parallel.

[0012] Furthermore, the movable end is located at an end of the linkage member away from the second rotating shaft.

[0013] Furthermore, the movable end is arranged on a side of the third rotating shaft away from the second rotating shaft.

[0014] Furthermore, the brake damping mechanism further comprises: a slider; The slider is in transmission connection with the transmission assembly, and the brake component and the damping component are both arranged on the slider.

[0015] Furthermore, the brake damping mechanism further comprises: a swing assembly; One end of the swing component is a rotating end and is arranged on the slider; the damping member is a damping wheel, and the damping wheel is arranged at the swing end of the swing component.

[0016] Furthermore, the swing assembly includes: a mounting shaft, a mounting bracket, and an elastic buffer; The mounting shaft is provided on the slider and extends in the horizontal direction; One end of the mounting frame is arranged on the mounting shaft and is slidably matched with the mounting shaft, the mounting frame is rotatably connected to the slider, and the damping wheel is arranged on the mounting frame; The elastic buffer is arranged on the installation shaft and two ends thereof are respectively in contact with the installation frame and the sliding block.

[0017] Furthermore, the brake damping mechanism further includes a limiter, which is provided on the slider and slidably cooperates with the slider, the sliding direction of the limiter is the same as the moving direction of the brake member and the damping member, and the limiter is used to connect to the vehicle body; The transmission assembly includes a transmission wire and a limit sleeve.

[0020] Beneficial effects: In the damping brake device provided by the present application, the position of the brake damping mechanism is adjusted by driving the transmission component through the driving mechanism, and the driving end can be driven by operating the driving mechanism so that the driving end can be switched from the initial position to the first gear, the second gear, and the third gear, thereby driving the brake damping mechanism to move accordingly. When in use, the damping brake device can be installed on the vehicle body so that the brake damping mechanism is located above the wheel, and the driving end is switched to the first gear to drive the brake member and the damping member to move, so that the brake member and the damping member move down together until the brake member contacts the wheel to realize the braking function. When the driving end is stopped, the brake The parts, the damping parts and the driving end all perform a return motion to their initial positions under the action of the reset part. Similarly, the driving end can be switched to the second gear or the third gear by operating the driving mechanism. When the driving end is switched to the second gear, the damping wheel contacts the wheel and there is a gap between the brake pad and the wheel, thereby achieving damping and deceleration of the wheel. When the driving end is switched to the third gear, the brake part contacts the wheel to stop the wheel from rotating. Without operating the driving mechanism, the driving end can stay in the second gear or the third gear to achieve the effect of damping and deceleration or parking. The damping and deceleration or parking state can be contacted by operating the driving mechanism to reset again.

[0021] Through the combined structure of the drive mechanism, transmission assembly and brake damping mechanism, the present application can realize braking, damping deceleration and parking operations by operating only the drive mechanism, and there is no need to bend over to operate damping deceleration or parking, which is very convenient to use.

[0032] The present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0033] Combine Figures 1 to 5 The damping brake device provided in this embodiment includes a driving mechanism 100, a transmission assembly 200 and a brake damping mechanism 300.

[0034] The drive mechanism 100 comprises a driving end and a movable end, the driving end having at least first, second, and third gear positions, and the movable end and the driving end are in transmission connection. One end of the transmission assembly 200 is in transmission connection with the movable end. A brake damping mechanism 300 is in transmission connection with the other end of the transmission assembly 200. The brake damping mechanism 300 comprises a brake member, a damping member, and a reset member 301. The brake and damping members are arranged sequentially in a direction away from the transmission assembly 200, and the brake and damping members move to compress or release the reset member 301.

[0035] Furthermore, when the driving end is in the first gear, the brake member and the damping member move a first distance in a direction away from the transmission assembly 200. When the driving end is in the second gear, the brake member and the damping member move a second distance in a direction away from the transmission assembly 200. When the driving end is in the third gear, the brake member and the damping member move the first distance in a direction away from the transmission assembly 200.

[0036] It should be noted that, in this embodiment, the second distance is smaller than the first distance, the driving mechanism 100 is used for manual driving, and the driving end can stay at the second gear position or the third gear position.

[0037] Combine Figures 6 to 9During assembly, the slider is mounted on the vehicle frame above the wheel, with a gap between the damping wheel 320 and the wheel that is no greater than the second distance, ensuring that the damping wheel 320 can abut against the wheel during its downward movement. Similarly, the linear distance between the brake pad 350 and the wheel is no greater than the first distance, ensuring that the brake pad 350 can abut against the wheel during its downward movement to achieve a braking or parking effect.

[0038] Combine Figure 12 Specifically, the damping brake device provided in this embodiment needs to be installed on the frame of a device such as a walker, and the driving mechanism 100 is installed at the handlebar so that the user can operate the driving mechanism 100 when holding the handlebar.

[0039] The brake damping mechanism 300 is arranged above the wheel so that the damping member can be located between the brake member and the wheel. The damping member, brake member, transmission assembly 200 and drive mechanism 100 are arranged in sequence in a direction away from the wheel so that when the drive mechanism 100 is operated, the brake member and the damping member can be driven to move toward the wheel.

[0040] When the driving 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 driving end is in the first and third gears, the brake and damping elements move a greater distance, causing both to contact the wheel, thus stopping the wheel. The driving mechanism 100 drives the transmission assembly 200 to adjust the position of the brake and damping mechanism 300. By operating the driving mechanism 100, the driving end can be driven to shift from its initial position to the first, second, and third gears, thereby driving the brake and damping mechanism 300 to move accordingly.

[0041] When the driving end stops operating, if the driving end is in the first gear, the brake component, the damping component and the driving end all perform a return motion to the initial position under the action of the reset component 301. If the driving end is in the second gear or the third gear, without operating the driving mechanism 100 again, the driving end can stay in the second gear or the third gear to achieve the effect of damping deceleration or parking. The damping deceleration or parking state can be released by re-operating the driving mechanism 100 to reset. Since the driving mechanism 100 in this embodiment is arranged at the handlebar of the vehicle body, it can be operated directly by hand when in use, and the braking, damping deceleration and parking operations can be achieved by only operating the driving mechanism 100, without bending over to operate during damping deceleration or parking, which is very convenient to use.

[0042] In this embodiment, the drive mechanism 100 includes a fixed member 110, a throttle 120, and a linkage 130. The fixed member 110 has a mounting space. The throttle 120 is rotatably connected to the fixed member 110. One end of the throttle 120 serves as a driving end and is located within the mounting space. The other end extends outside the fixed member 110 and is manually operated. The linkage 130 is disposed on the fixed member 110 and is rotatably connected to the fixed member 110. The linkage 130 is in transmission connection with the throttle 120 to drive the linkage 130 in rotation. The movable end is disposed on the linkage 130.

[0043] In this embodiment, the fixing part 110 is used to connect with the vehicle body and the frame to form a setting space, and the linkage part 130 is set in the setting space of the fixing part 110. An opening is set on one side of the fixing part 110, and the turning handle 120 is inserted into the opening, and one end of the turning handle 120 is rotatably connected to the linkage part 130 to drive the linkage part 130 to rotate. The other end of the turning handle 120 is passed through the opening so that the user can operate the turning handle 120 to rotate by pinching or pressing down, thereby driving the movable end on the linkage part 130 to move upward, so that the movable end can drive the brake part and the damping part to move through the transmission assembly 200.

[0044] Combine Figure 2 、 Figure 11 In this embodiment, a rotation hole 122 is provided at the driving end of the rotation handle 120. An initial groove, a first groove body 123, a second groove body 124 and a third groove body 125 are provided on one side wall of the rotation hole 122.

[0045] In the initial position, the initial groove is located at the top of the rotating hole 122, the first groove body 123 is located on one side of the rotating hole 122, and the second groove body 124 and the third groove body 125 are located on the other side of the rotating hole 122. The heights of the initial groove, the second groove body 124, and the third groove body 125 decrease in sequence, and the height of the third groove body 125 is the same as that of the first groove body 123. A first rotating shaft 111 is fixedly provided in the fixing member 110 and inserted into the rotating hole 122. When the driving end is in the first gear, the first rotating shaft 111 is located in the first groove body 123. When the driving end is in the second gear, the first rotating shaft 111 is located in the second groove body 124. When the driving end is in the third gear, the first rotating shaft 111 is located in the third groove body 125.

[0046] Specifically, in this embodiment, when the vehicle is running normally, the damping brake device is in the initial position. Figure 9At this time, the first rotating shaft 111 is located in the initial groove. Since the first groove body 123, the second groove body 124, and the third groove body 125 are all located below the first groove body 123, the first rotating shaft 111 can be stably present in the first groove body 123 in the absence of external force intervention, so that the wheel and the brake and damping parts are in a spaced-apart state, avoiding the brake and damping parts from contacting the tire and affecting driving.

[0047] When braking is required, the handle 120 can be rotated so that the handle 120 rotates around the first rotation axis 111 until the first rotation axis 111 enters the first slot 123. Figure 6 In this embodiment, the specific action is to lift the throttle 120 to achieve engagement between the first rotating shaft 111 and the first slot 123. During this process, because the linkage member 130 is rotationally connected to the throttle 120, the connection point of the rotating member with the throttle 120 rotates along with the throttle 120, thereby pulling the transmission assembly 200 to drive the brake damping mechanism 300. Driven by the transmission assembly 200, the brake member and the damping member move toward the wheel a first distance, causing the brake member to contact the wheel to achieve a braking action.

[0048] It should be noted that, in this embodiment, a support portion 131 is provided on the linkage member 130. When the damping brake device is in the initial state or the first gear, the support portion 131 abuts against the rotating end of the turn handle 120 so that the rotating end of the turn handle 120 will not move downward when the turn handle 120 is lifted, thereby pulling the connection with the linkage member 130 upward, so that the first rotating shaft 111 can smoothly enter the first groove body 123.

[0049] When encountering a road condition with a large slope, in order to prevent the vehicle from traveling too fast, the damping brake device can be switched to a slow-down damping state, that is, the first rotating shaft 111 enters the second groove 124. Figure 7 Specifically, the second slot body 124 is provided on a side of the initial slot away from the first slot body 123. Therefore, in this embodiment, when the first rotating shaft 111 is located in the initial slot, the turning handle 120 is rotated by pressing down until the first rotating shaft 111 enters the second slot body 124. At this time, the brake member and the damping member move down a second distance, the damping member contacts the wheel and the brake member does not contact the wheel, and the wheel realizes a deceleration action under the action of the damping member.

[0050] Moreover, in this embodiment, when parking is required, the turning handle 120 can be pressed down again in the slow damping state, combined with Figure 8, the throttle 120 is rotated again to disengage the first rotating shaft 111 from the second slot 124 and enter the third slot 125. The brake and damping elements move downward again until the brakes contact the wheel, thereby achieving a stop. Furthermore, both sides of the second slot 124 and the third slot 125 have limit mechanisms. Therefore, when the first rotating shaft 111 is in the second slot 124 or the third slot 125, if there is no external force (i.e., the user does not operate the throttle 120), the first rotating shaft 111 can remain in the second slot 124 or the third slot 125 for a long time, thereby achieving deceleration and parking of the vehicle.

[0051] In this embodiment, a limit portion 121 is provided on the throttle 120. The limit portion 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 side wall of the lower end of the limit portion 121 on the side close to the fixing member 110 abuts against the outer wall of the fixing member 110.

[0052] Specifically, the limiting portion 121 in this embodiment is located in the middle section of the throttle 120 and protrudes outward and extends downward from the throttle 120. When the damping brake device is in the initial state, braking state, or damping state, a gap exists between the limiting portion 121 and the fixing member 110. When the throttle 120 is rotated until the first rotating shaft 111 mates with the third slot 125, the limiting portion 121 abuts against the side wall of the fixing member 110 located below the opening, thereby limiting the position of the throttle 120 and indicating that the throttle 120 has been rotated into position.

[0053] Please combine Figure 11 Specifically, in this embodiment, a smooth transition is formed 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 to keep the driving end in the second gear or the third gear.

[0054] In this embodiment, the second slot 124 and the third slot 125 are both arc-shaped. The junctions between the initial slot and the second slot 124, and between the second slot 124 and the third slot 125, are both convex, forming stopper protrusions. With this structure, when the throttle 120 is rotated, the first rotating shaft 111 can smoothly enter the second slot 124 or the third slot 125 along the smooth transition and arc-shaped structure.

[0055] Moreover, after the first rotating shaft 111 enters the second groove body 124 or the third groove body 125 , the limiting protrusions can form limits from both sides to prevent the first rotating shaft 111 from falling out, thereby ensuring that the first rotating shaft 111 is stably present in the second groove body 124 and the third groove body 125 .

[0056] In this embodiment, a second rotating shaft 112 is fixedly disposed within the fixing member 110. A third rotating shaft 126 is disposed between the throttle 120 and the linkage member 130. The linkage member 130 is rotatably connected to the throttle 120 via the third rotating shaft 126. The linkage member 130 is rotatably connected to the fixing member 110 via 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.

[0057] 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 member 130 is the same, and when the handle 120 rotates, it drives the linkage member 130 to rotate in the same direction.

[0058] In this embodiment, the third rotating shaft 126 is provided on the turning handle 120 , and the linkage member 130 is provided with an axial hole to be sleeved onto the outside of the third rotating shaft 126 to achieve a rotational connection.

[0059] Furthermore, in this embodiment, the moving end is located at an end of the linkage member 130 away from the second rotation shaft 112 .

[0060] Specifically, the second rotating shaft 112, the third rotating shaft 126 and the movable end in this embodiment are arranged along a straight line at intervals. The farther the distance between the movable end and the second rotating shaft 112, the longer the stroke of the movable end, that is, the greater the distance that the transmission assembly 200 can be driven to move, thereby ensuring that the moving distance of the brake and damping components is sufficient to contact the tire.

[0061] In this embodiment, the movable end is disposed on a side of the third rotating shaft 126 away from the second rotating shaft 112 .

[0062] In this embodiment, the third rotating shaft 126 and the movable end are arranged in sequence in a direction away from the second rotating shaft 112. The third rotating shaft 126 and the movable end are arranged on the same side of the second rotating shaft 112, thereby saving the space occupied by the linkage member 130 and reducing the volume of the fixing member 110.

[0063] It should be noted that in this embodiment, the linkage member 130 is a hollow structure, the second rotating shaft 112 and the moving end are respectively arranged at the two ends of the linkage member 130, and the third rotating shaft 126 is arranged in the middle section of the linkage member 130 and close to the moving end. The moving end in this embodiment is a ring structure so that the transmission assembly 200 can be connected to the mobile end.

[0064] In this embodiment, the brake damping mechanism 300 further includes a slider which is in transmission connection with the transmission assembly 200, and on which both the brake member and the damping member are mounted.

[0065] In this embodiment, the slider is used to be mounted on the vehicle body and the frame, and the transmission assembly 200 drives the slider to move to drive the brake component and the damping component to move.

[0066] 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. The damping member is a damping wheel 320 , which is disposed at the swing end of the swing assembly 310 .

[0067] The swing assembly 310 can swing slightly when subjected to force. The damping wheel 320 is arranged 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, thereby preventing the damping wheel 320 from being damaged due to excessive vibration.

[0068] 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 mounted on the slider and extends horizontally. One end of the mounting bracket 312 is mounted on the mounting shaft 311 and slidably engages with the mounting shaft 311. The mounting bracket 312 is rotationally connected to the slider, and the damping wheel 320 is mounted on the mounting bracket 312. The elastic buffer 313 is mounted on the mounting shaft 311, with its ends respectively contacting the mounting bracket 312 and the slider.

[0069] In this embodiment, the sidewall of the slider is provided with an internally threaded mounting hole, and the mounting shaft 311 is threadedly inserted into the mounting hole. Specifically, in this embodiment, a stopper with a larger 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 through which the mounting bracket 312 is sleeved on the mounting shaft 311 and can move axially along the mounting shaft 311. The stopper prevents the mounting bracket 312 from falling along the end of the mounting shaft 311.

[0070] The elastic buffer member 313 in this embodiment is specifically a buffer spring, which is sleeved on the mounting shaft 311 , with one end of the buffer spring abutting against the side wall of the slider and the other end abutting against the side wall of the mounting bracket 312 .

[0071] Under this structure, when the damping wheel 320 contacts the wheel body and is subjected to force, the mounting frame 312 moves toward the slider along with the damping wheel 320 to achieve buffering of the mounting frame 312 and the damping wheel 320, thereby preventing the mounting frame 312 and the damping wheel 320 from being deformed due to excessive force.

[0072] Moreover, in this embodiment, the hole on the mounting bracket 312 is a long hole with an opening extending in the vertical direction, and the mounting shaft 311 is passed 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 long hole, thereby further improving the shock absorbing effect.

[0073] In addition, in this embodiment, the brake damping mechanism 300 also includes a protective shell, one end of which is connected to the slider and extends horizontally. The protective shell cover is arranged above the mounting shaft, buffer spring, damping wheel 320 and mounting frame 312 to form a protective structure.

[0074] In this embodiment, the brake damping mechanism 300 further includes a stopper 330, which is mounted on the slider and slidably engages with the slider. The stopper 330 slides in the same direction as the brake and damping components and is used to connect to the vehicle body. The transmission assembly 200 includes a transmission wire and a stopper sleeve. One end of the transmission wire is in driving connection with the moving end, and the other end is connected to the stopper 330. The stopper sleeve is mounted on the transmission wire, with one end abutting the moving end and the other end abutting the slider.

[0075] Specifically, in this embodiment, the slider is provided with a sliding hole extending in the same direction as the movement of the brake pad 350 and the damping wheel 320. One end of the stopper 330 is provided with a thread. When the slider is mounted on the vehicle body or frame, the stopper 330 is inserted into the sliding hole and connected to the vehicle body or frame via a threaded engagement. In this structure, the slider can slide along the vehicle body or frame and, when it reaches its limit position, abuts against the stopper 330, thereby limiting the slider's position and preventing it from sliding out of its pre-set path, which would prevent the brake pad 350 or the damping wheel 320 from contacting the wheel body under the drive of the transmission assembly 200.

[0076] Furthermore, the transmission wire in this embodiment is a brake wire, and the limiting sleeve is a brake wire skin. One end of the brake wire is tied to the annular structure of the moving end, and the other end is in contact with the slider.

[0077] The brake cable sheath is positioned outside the brake cable, with one end of the brake cable sheath abutting the bottom end of the fixing member 110 and the other end abutting the stopper 330. In this configuration, when the throttle 120 is lifted or pressed down, the movable end of the linkage member 130 swings upward, pulling the brake cable upward. At this point, the brake cable sheath is not pulled; instead, it is squeezed by the fixing member 110 and moves down along the brake cable, thereby depressing the slider, which moves downward along the slide hole, thereby moving the damping wheel 320 and brake pad 350 toward the wheel body.

[0078] 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 the two ends of the reset member 301 are respectively in contact with the positioning pin 340 and the limit member 330.

[0079] Specifically, a positioning pin 340 is inserted into the slider, with its top end located at the bottom end of the slide hole. In this embodiment, the return element 301 is a return spring, the top end of which abuts the bottom end of the positioning pin 340, which in turn abuts the top end of the stopper 330. In this configuration, when the brake cable pushes the slider downward, the positioning pin 340 moves with the slider and, together with the stopper 330, compresses the return spring.

[0080] When the first rotating shaft 111 is located between the second groove 124 and the third groove 125, the limiting ridge can limit the first rotating shaft 111, and the return spring cannot push the brake cable to reset, so that the damping brake device can maintain the deceleration damping state or the parking state. When the first rotating shaft 111 is located between the first groove 123, if the throttle 120 stops being lifted, the throttle 120 loses external force, and no limiting structure is provided between the first groove 123 and the initial groove. At this time, the return spring performs a restorative deformation to push the brake cable to reset, thereby pulling the linkage 130 to reset, and then pulling the throttle 120 to rotate to the initial position, to achieve automatic reset after braking.

[0081] When using the damping brake device provided by this application, the damping wheel 320 will first contact the wheel, regardless of whether the brake is in the parking state or the braking state. For frail elderly people, in an emergency, they may not be able to instantly achieve the required force for a complete handbrake application. However, the initial force is sufficient to cause the damping wheel 320 to first contact the wheel to decelerate, and then the brake pad 350 to contact the wheel to brake, thereby meeting the elderly's emergency braking needs.

[0082] The walking aid provided in this embodiment includes the damping brake device provided in the above embodiment.

[0083] The walking aid device includes a frame and wheels, and a handlebar extending in a horizontal direction is provided at the top of the frame.

[0084] See Figure 10 The fixing member 110 of the damping brake device is sleeved on the frame below the handlebar so that the extending direction of the turning handle 120 is the same as the extending direction of the handlebar, which is convenient for the user to lift up and press down the turning handle 120.

[0085] In this embodiment, the slider is mounted on the vehicle frame above the wheel, and the gap between the damping wheel 320 and the wheel is no greater than the second distance, ensuring that the damping wheel 320 can abut against the wheel body when it moves downward to the extreme position. Similarly, the linear distance between the brake pad 350 and the wheel is no greater than the first distance, ensuring that the brake pad 350 can abut against the wheel when it moves downward to the extreme position to achieve a braking or parking effect.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
