Description

Technical Field

[0001] This invention relates to the field of rehabilitation assistive devices, specifically to an adjustable support force standing aid device, and also to a walking aid device. Background Technology

[0002] With the increasing aging of the population and the growing demand for rehabilitation medicine, assistive devices for standing up are widely used for people with limited mobility, such as the elderly, people with disabilities, and postoperative rehabilitation patients. Their core function is to help users overcome the difficulty of standing up and reduce the risk of falls through the cooperation of mechanical structure and power components.

[0003] Patent CN112842724B discloses an integrated standing and walking assistance device for the elderly, which combines walking assistance and standing assistance. By using underarm support, it avoids the limitation of sitting furniture on the function of assisting to stand, allowing the elderly to use a single device to assist to stand and walk at home, making it convenient for the elderly to move around at home. The movable bracket supports the entire device and provides mobility. The support mechanism assists under the armpits to achieve the function of assisting to stand, and the force adjustment mechanism can freely adjust the support force of the device, so as to achieve the function of low resistance when sitting down and high support force when standing up.

[0004] While the above solution achieves the function of "low resistance when sitting down and high support force when standing up," it relies on a controllable gas spring as the sole power source to drive the support mechanism. During the extension of the piston rod of the controllable gas spring, its thrust direction is always along its own axis. The movement of the support mechanism depends on the oscillation of the parallelogram mechanism. When the controllable gas spring pushes the force-adjusting mechanism upwards, the position of the lever arm of the thrust acting on the parallelogram mechanism continuously changes with the oscillation of the mechanism. Specifically, in the initial stage of the user standing up, the long connecting rod frame of the parallelogram mechanism is at a lower angle, and the thrust of the controllable gas spring is in the vertical direction. The vertical component of the force is relatively small, and the upward speed of the support mechanism is slow. However, as the standing process progresses, the long connecting rod frame gradually rotates upward, and the angle between the controllable gas spring and the horizontal direction continuously increases. Consequently, the vertical component of its thrust also continuously increases. This change in force causes the support mechanism to still have a relatively fast upward speed when it rotates to the highest point, making it impossible to achieve natural speed buffering. At this time, if the controllable gas spring suddenly stops pushing due to its travel limit, or if the user's body leaves the support prematurely, the inertia of the support mechanism can easily cause the handrail and underarm support rod to "rush to the top," which deviates from the core requirement of "smoothly assisting standing up." Summary of the Invention

[0005] To address the aforementioned issues, an adjustable support force standing aid device is provided. By gradually reducing the vertical force during the standing process and gradually slowing down the rotation speed during the sitting process, it effectively avoids imbalance and impact problems caused by sudden loss of support force or sudden change in speed, thereby reducing the risk of falls when users stand up and sit down.

[0006] To address the problems of existing technologies, the present invention provides an adjustable support force standing aid device, comprising a movable support, a support arm structure disposed on the top of the movable support, and a force adjustment mechanism disposed inside the support arm structure. The force adjustment mechanism includes a female base capable of moving along the support arm structure. The adjustable support force standing aid device further includes a standing support mechanism and a sitting support mechanism. The standing support mechanism includes a folding support, a first fixing component, a first driver, and a quick-connect component. The end of the folding support is hinged to the top of the movable support. The first fixing component is used to fix the folding support and the movable support. The first driver is disposed inside the folding support, and one end of the first driver is rotatably connected to the folding support. The quick-connect component is used to connect the female base and the first driver. The sitting support mechanism includes a second driver, which is disposed inside the movable support. One end of the second driver is provided with a rotating shaft and is rotatably connected to the movable support. The other end of the second driver is connected to the female base.

[0007] Preferably, the sitting support mechanism further includes two sliding guide components and a fourth fixing component; the two sliding guide components are respectively disposed at both ends of the rotating shaft to limit the two ends of the rotating shaft to move synchronously in the vertical direction; the fourth fixing component is used to fix the height of the rotating shaft in the vertical direction.

[0008] Preferably, the fourth fixing component includes two docking blocks and a fixing drive component; the two docking blocks are used to dock the two ends of the rotating shaft respectively, fixing the height of the rotating shaft in the vertical direction, and the docking blocks are provided with docking holes for docking with the rotating shaft; the fixing drive component is used to drive the two docking blocks to dock synchronously with the two ends of the rotating shaft.

[0009] Preferably, the sliding guide assembly includes a slider and a plurality of second guide rods; the slider is connected to the rotating shaft via a bearing; the plurality of second guide rods are respectively disposed on both sides of the rotating shaft, and the slider and the plurality of second guide rods are slidably connected.

[0010] Preferably, the first fixing component includes a guide sleeve and a fixing rod; the guide sleeve is disposed on the folding bracket; one end of the fixing rod is slidably disposed inside the guide sleeve, and the other end of the fixing rod passes through the folding bracket and is slidably connected to the folding bracket.

[0011] Preferably, the quick-connect assembly includes a connecting seat, a threaded sleeve, and a connecting screw; the connecting seat is disposed at the upper end of the female seat; the threaded sleeve is disposed on one side of the connecting seat for fixing the connecting screw; the connecting screw is used to connect the first driver and the connecting seat.

[0012] Preferably, the standing support mechanism further includes a second fixing component disposed within the folding bracket for fixing the first driver within the folding bracket.

[0013] Preferably, the standing support mechanism further includes a third fixing component, which includes a magnetic fixing component for fixing the folding bracket folded on one side of the movable bracket to the movable bracket.

[0014] Preferably, the third fixing component also includes a buffer component for absorbing the impact force when the folding bracket comes into contact with the movable bracket.

[0015] A walking aid device includes an adjustable support force standing aid device.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention provides a standing support mechanism and a sitting support mechanism. The folding bracket and the movable bracket are fixed as a whole by the first fixing component in the standing support mechanism. With the help of the quick-connect component, the first driver and the female seat are quickly connected, so that the first driver can stably transmit an upward pulling force to the support arm structure to assist the user in standing up. At the same time, as the support arm structure rotates, the vertical component of the pulling force of the first driver gradually decreases, and the rotation speed of the support arm slows down, so as to avoid the user losing balance due to loss of support when the support arm stops, ensuring that the standing process is impact-free and more stable. The second driver in the sitting support mechanism applies a downward pulling force to the support arm through the female seat, causing the support arm to rotate slowly, and the rotation speed gradually slows down as the angle increases, so that the user's body slowly sinks and sits down smoothly, avoiding impact caused by excessive sitting speed, reducing the risk of falling or bumping. Through the design of gradually decreasing vertical force during the standing process and gradually slowing down the rotation speed during the sitting process, the imbalance and impact problems caused by sudden loss of support or sudden change in speed are effectively avoided, reducing the risk of falling when the user stands up and sits down.

[0018] 2. The present invention is provided with a sliding guide component and a fourth fixing component. The fourth fixing component releases the fixing of the rotating shaft, so that the second driver is in an unrestrained follow-up state. It neither generates a reverse force to counteract the power of the first driver nor affects the rotation trajectory of the support arm structure due to its own rigidity. This ensures that the power of the standing support mechanism can be fully transmitted to the support arm structure, assisting the user to stand up smoothly.

[0019] 3. The present invention provides two docking blocks and a fixed drive assembly. The fixed drive assembly drives the two docking blocks to move closer or further away synchronously, so that both ends of the rotating shaft can be simultaneously fitted or disengaged by the docking holes, thereby avoiding bending deformation caused by uneven force on the rotating shaft due to unilateral fixation.

Detailed Implementation

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 11 As shown: An adjustable support force standing aid device includes a movable support 1, a support arm structure 2 disposed on the top of the movable support 1, and a force adjustment mechanism 3 disposed inside the support arm structure 2. The force adjustment mechanism 3 includes a female seat 31 that can move along the support arm structure 2. The adjustable support force standing aid device also includes a standing support mechanism 4 and a sitting support mechanism 5. The standing support mechanism 4 includes a folding bracket 41, a first fixing component 42, a first driver 43, and a quick-connect component 44. The end of the folding bracket 41 is hinged to the top of the movable support 1. The first fixing component 42 is used to fix the folding bracket 41 and the movable support 1. The first driver 43 is disposed inside the folding bracket 41, and one end of the first driver 43 is rotatably connected to the folding bracket 41. The quick-connect component 44 is used to connect the female seat 31 and the first driver 43. The sitting support mechanism 5 includes a second driver 51, which is disposed inside the movable support 1. One end of the second driver 51 is provided with a rotating shaft 511 that is rotatably connected to the movable support 1, and the other end of the second driver 51 is connected to the female seat 31.

[0034] When the user needs to stand up, the assistant can manually or electrically rotate the folding bracket 41, which is originally folded, around its hinge point with the top of the movable bracket 1, until the folding bracket 41 and the movable bracket 1 are rigidly aligned. Then, the first fixing component 42 is operated to fix the folding bracket 41 and the movable bracket 1 into a whole. Next, the first driver 43 is quickly connected to the female seat 31 in the force adjustment mechanism 3 through the quick-connect component 44. At this time, the standing assistance device enters the standing assistance ready state. The first driver 43 forms a power transmission path with the support arm structure 2 through the female seat 31, while the second driver 51 is temporarily in a non-working state and does not apply force to the support arm structure 2. When the support arm 2 is positioned under the user's armpit, the first actuator 43 is activated. The first actuator 43 outputs driving force, which applies an upward pulling force to the support arm 2 via the female connector 31. This causes the support arm 2 to rotate upwards around its connection point with the movable support 1, thereby assisting the user in standing up through underarm support. During this process, due to the rotational trajectory characteristics of the support arm 2, the vertical component of the pulling force applied by the first actuator 43 gradually decreases as the rotation angle of the support arm increases. This gradually slows down the upward rotation speed of the support arm 2, effectively preventing the user from suddenly losing upward support and experiencing a sense of imbalance or impact when the support arm 2 reaches its highest position and stops moving. This ensures a smooth and safe standing process. After the user fully stands up and is able to stand independently, the second actuator 51 activates, applying an upward supporting force to the support arm structure 2 via the female base 31 to maintain its current balance. Then, the quick-connect assembly 44 is released, disconnecting the power transmission between the first actuator 43 and the female base 31. Simultaneously, the first fixing assembly 42 is operated to remove the fixation between the folding bracket 41 and the movable bracket 1, rotating the folding bracket 41 around the hinge point to one side of the movable bracket 1. This prevents the folding bracket 41 from obstructing the user's view and does not affect the user's normal walking or activities. When the user needs to sit down, they first re-align their armpits with the support arm structure 2. At this time, the standing assistance device switches to sitting assistance mode, and the second actuator 51, through the female base 31, applies an upward supporting force to the support arm structure 2. 2. Applying a downward pulling force causes the support arm structure 2 to slowly rotate downward around its connection with the movable support 1. As the support arm structure 2 rotates from a vertical support state to a horizontal bearing state, the downward rotation speed of the support arm structure 2 gradually decreases as the rotation angle increases. This ensures that the user's body slowly sinks down with the assistance of the support arm structure 2 and finally sits steadily on the chair or bed, avoiding impact on the buttocks and contact surface due to excessive sitting speed, and reducing the risk of falls or bumps. Through the design of gradually decreasing vertical force during standing up and gradually slowing down the rotation speed during sitting down, the system effectively avoids imbalance and impact problems caused by sudden loss of support or sudden change in speed, reducing the risk of falls when the user stands up and sits down.

[0035] Reference Figure 3As shown: The seat support mechanism 5 also includes two sliding guide components 52 and a fourth fixing component 53; the two sliding guide components 52 are respectively disposed at both ends of the rotating shaft 511 to limit the two ends of the rotating shaft 511 to move synchronously in the vertical direction; the fourth fixing component 53 is used to fix the height of the rotating shaft 511 in the vertical direction.

[0036] Before the user starts the standing support mechanism 4, the assistant must first operate the fourth fixing component 53 to release its locking state on the rotating shaft 511. At this time, the second driver 51 loses its vertical fixing point, allowing it to move along the sliding guide component 52. After the standing support mechanism 4 enters the working state, the first driver 43 applies an upward pulling force to the support arm structure 2 through the female seat 31, causing the support arm structure 2 to rotate upward around its connection with the movable bracket 1. Since the support arm structure 2 is connected to the second driver 51 through the female seat 31, the rotation of the support arm structure 2 will synchronously pull the second driver 51. The second driver 51 is always in a follow-up state, neither actively applying force to the support arm structure 2 nor hindering the rotation of the support arm structure 2 due to its own position limitation. After the support arm structure 2 assists the user to stand up completely... The second actuator 51 is activated, extending its length. The rotating shaft 511 moves downward along the vertical channel of the sliding guide assembly 52 until it reaches the locking position of the fourth fixing assembly 53. The fourth fixing assembly 53 then re-fixes the rotating shaft 511, providing a stable support point for the rotating shaft 511 end of the second actuator 51. After fixing, the second actuator 51 can transmit force normally, applying an upward supporting force to the support arm structure 2 to ensure that the support arm structure 2 remains balanced. The fourth fixing assembly 53 releases the fixing of the rotating shaft 511, allowing the second actuator 51 to be in an unrestrained follow-up state. This prevents the generation of a reverse force that counteracts the power of the first actuator 43, and also prevents the rigidity of the actuator from affecting the rotation trajectory of the support arm structure 2. This ensures that the power of the standing support mechanism 4 can be fully transmitted to the support arm structure 2, assisting the user in standing up smoothly.

[0037] Reference Figure 4 and Figure 5 As shown: The fourth fixing component 53 includes two docking blocks 531 and a fixing drive component 532; the two docking blocks 531 are respectively used to dock the two ends of the rotating shaft 511 and fix the height of the rotating shaft 511 in the vertical direction. The docking blocks 531 are provided with docking holes 5311 for docking with the rotating shaft 511; the fixing drive component 532 is used to drive the two docking blocks 531 to dock synchronously with the two ends of the rotating shaft 511.

[0038] Specifically, the fixed drive assembly 532 includes a bidirectional lead screw 5321 and two moving blocks 5322. The bidirectional lead screw 5321 is parallel to the rotating shaft 511. The two moving blocks 5322 are threadedly connected to the two threaded portions of the bidirectional lead screw 5321, and the two moving blocks 5322 are respectively connected to the two mating blocks 531.

[0039] When the user prepares to stand up, the bidirectional lead screw 5321 in the fixed drive assembly 532 rotates clockwise. The two moving blocks 5322, which are engaged with the threaded part, move in opposite directions along the axis of the bidirectional lead screw 5321. The moving blocks 5322 simultaneously drive the connecting blocks 531 connected to them away from both ends of the rotating shaft 511, so that the connecting holes 5311 on the connecting blocks 531 are completely disengaged from the rotating shaft 511, releasing the fitting constraint on the rotating shaft 511. At this time, the rotating shaft 511 regains the freedom of vertical movement along the sliding guide assembly 52, and the second driver 51 enters the follow-up state, which will not hinder the subsequent operation of the standing support mechanism 4. When the user has fully stood up, the second driver 51 needs to be reset and fixed to support the support arm structure 2. The bidirectional lead screw 5321 in the fixed drive assembly 532 rotates counterclockwise, and the two reverse threads drive the two moving blocks 5322. The moving block 5322 moves in the opposite direction along the axis of the bidirectional lead screw 5321. The moving block 5322 drives the docking block 531 to move closer to the rotating shaft 511 in sync, so that the docking hole 5311 fits into both ends of the rotating shaft 511. The mechanical constraint restricts the movement of the rotating shaft 511 in the vertical direction. After the fitting is completed, the fixed drive assembly 532 stops working, the bidirectional lead screw 5321 remains stationary, and the two docking blocks 531 firmly lock the height of the rotating shaft 511 through the docking hole 5311, thereby fixing the position of the second driver 51. This allows the second driver 51 to stably apply an upward supporting force to the support arm structure 2. The bidirectional lead screw 5321 drives the two docking blocks 531 to move closer or further away in sync, so that both ends of the rotating shaft 511 can be fitted or disengaged by the docking hole 5311 at the same time. This avoids bending deformation of the rotating shaft 511 due to uneven force caused by unilateral fixing.

[0040] Reference Figure 4 and Figure 5 As shown: The sliding guide assembly 52 includes a slider 521 and a plurality of second guide rods 522; the slider 521 is connected to the rotating shaft 511 through a bearing; the plurality of second guide rods 522 are respectively disposed on both sides of the rotating shaft 511, and the slider 521 and the plurality of second guide rods 522 are all slidably connected.

[0041] When the support arm structure 2 moves the second actuator 51, the rotating shaft 511 moves synchronously with the second actuator 51. The movement of the rotating shaft 511 causes the slider 521 to slide along the second guide rod 522. At this time, multiple second guide rods 522 form a rigid constraint on the slider 521, and the slider 521 can only move in the vertical direction of the second guide rod 522, and cannot be horizontally offset or tilted. This avoids the rotating shaft 511 from shaking, jamming or offset due to uneven force, and ensures that the second actuator 51 can move smoothly with the support arm structure 2 without interfering with the operation of the standing support mechanism 4. When the user is fully standing up, the second actuator 51 needs to reset to support the support arm structure 2. The slider 521 slides along the second guide rod 522, causing the rotating shaft 511 to descend smoothly until both ends of the rotating shaft 511 are in contact with the second guide rod 522. The docking holes 5311 of the docking block 531 in the fourth fixing component 53 are fully aligned, providing a precise positional reference for the subsequent locking of the height of the rotating shaft 511 by the fourth fixing component 53. After the fourth fixing component 53 is locked, the slider 521 and the second guide rod 522 remain relatively stationary, further assisting in fixing the position of the rotating shaft 511 and ensuring that the rotating shaft 511 does not shift during the support process. Through the sliding connection between the slider 521 and multiple second guide rods 522, the rotating shaft 511 is strictly constrained to move only in the vertical direction, thereby avoiding problems such as horizontal offset or tilting of the rotating shaft 511 during follow-up or reset, ensuring that the rotating shaft 511 always moves along the preset trajectory, and providing a guarantee for the smooth movement of the second driver 51 and the precise locking of the fourth fixing component 53.

[0042] Reference Figure 6 and Figure 7 As shown: The first fixing component 42 includes a guide sleeve 421 and a fixing rod 422; the guide sleeve 421 is disposed on the folding bracket 41; one end of the fixing rod 422 is slidably disposed in the guide sleeve 421, and the other end of the fixing rod 422 passes through the folding bracket 41 and is slidably connected to the folding bracket 41; the movable bracket 1 is provided with a fixing hole that mates with the fixing rod 422.

[0043] When the user needs to stand up, the assistant manually flips or electrically drives the folding bracket 41 to rotate around its hinge point with the top of the movable bracket 1. During this process, the folding bracket 41 drives the guide sleeve 421 and the fixed insertion rod 422 to rotate synchronously until the folding bracket 41 is completely above the movable bracket 1. At this time, the fixed insertion rod 422 is directly above the fixed insertion hole of the movable bracket 1, and the axis of the fixed insertion rod 422 is completely aligned with the axis of the fixed insertion hole, completing the hole alignment before fixing and ensuring that the fixed insertion rod 422 can be smoothly inserted later. Then, the fixed insertion rod 422 is pushed to move along its own axis toward the fixed insertion hole until the end of the fixed insertion rod 422 away from the guide sleeve 421 is completely inserted into the fixed insertion hole of the movable bracket 1. Inside the hole, the fixed insertion rod 422 simultaneously passes through the fixed insertion holes of the guide sleeve 421, the folding bracket 41, and the movable bracket 1, forming a rigid connection. This locks the folding bracket 41 and the movable bracket 1 into a single, immovable unit, providing stable structural support for the subsequent output power of the first driver 43. This prevents power transmission failure due to loosening of the folding bracket 41 during the support process. Through the cooperation of the fixed insertion rod 422 and the fixed insertion hole, the folding bracket 41 and the movable bracket 1 form a rigid integrated structure, which can effectively disperse the support force generated when the first driver 43 is working. This prevents shaking, displacement, or deformation at the connection of the folding bracket 41, ensuring that the power of the first driver 43 can be stably transmitted to the support arm structure 2.

[0044] Reference Figure 6 and Figure 8 As shown: the quick-connect assembly 44 includes a connecting seat 441, a screw sleeve 442 and a connecting screw 443; the connecting seat 441 is disposed at the upper end of the female seat 31; the screw sleeve 442 is disposed on one side of the connecting seat 441 and is used to fix the connecting screw 443; the connecting screw 443 is used to connect the first driver 43 and the connecting seat 441.

[0045] After the folding bracket 41 and the movable bracket 1 are fixed together by the first fixing component 42, the first driver 43 needs to be connected to the female seat 31 to transmit power. At this time, the assistant first adjusts the position of the first driver 43 so that the axis of the connecting screw 443 at the output end of the first driver 43 is aligned with the axis of the connecting hole on the connecting seat 441. Since the connecting seat 441 is fixed to the upper end of the female seat 31, the female seat 31 can move along the support arm structure 2. The assistant can make fine adjustments to the position of the female seat 31 or the angle of the first driver 43 to ensure that the connecting screw 443 can be smoothly aligned with the connecting hole of the connecting seat 441, thus completing the alignment calibration before connection. Then, the assistant holds the connecting screw 443. 3. Insert the threaded end of the connecting screw 443 into the connecting hole of the connecting seat 441, and then rotate the connecting screw 443. During the rotation, it engages with the internal thread of the threaded sleeve 442. At this time, the connecting screw 443 is connected to the connecting seat 441 through the thread fixing action of the threaded sleeve 442, thereby realizing the rigid connection between the first driver 43 and the female seat 31. When the user completes the standing action and needs to disconnect the connection between the first driver 43 and the female seat 31 to store the folding bracket 41, the assistant rotates the connecting screw 443 in the opposite direction to realize the quick disconnection between the first driver 43 and the female seat 31, thereby shortening the time for power connection and disconnection and improving operating efficiency.

[0046] Reference Figure 6 and Figure 9 As shown: The standing support mechanism 4 also includes a second fixing component 45, which is disposed inside the folding bracket 41 and is used to fix the first driver 43 inside the folding bracket 41.

[0047] Specifically, the second fixing component 45 includes a mounting base 451, a first magnetic block 452, and a first magnetic plate 453. The mounting base 451 is disposed on the first driver 43, the first magnetic block 452 is mounted on the mounting base 451, and the first magnetic plate 453 is fixed on the folding bracket 41. The first magnetic block 452 can be attracted to the first magnetic plate 453.

[0048] When the lifting support mechanism 4 is not working, the first magnetic block 452 installed on the mounting base 451 on the outer wall of the first driver 43 is aligned with the first magnetic plate 453 on the inner wall of the folding bracket 41. Under the action of magnetic force, the first magnetic block 452 will automatically be attracted to the first magnetic plate 453. Through the stable attraction between the first magnetic block 452 and the first magnetic plate 453, the first driver 43 can be firmly fixed in the folding bracket 41, effectively preventing the first driver 43 from swinging or colliding randomly during the movement of the device and the rotation of the folding bracket 41, thereby avoiding wear or damage to the first driver 43 due to collision and extending the service life of the first driver 43.

[0049] Reference Figure 6 , Figure 10 and Figure 11 As shown: The standing support mechanism 4 also includes a third fixing component 46, which includes a magnetic fixing component 461. The magnetic fixing component 461 is used to fix the folding bracket 41 folded on one side of the movable bracket 1 to the movable bracket 1.

[0050] Specifically, the magnetic fixing assembly 461 includes a bracket base 4611, a second magnetic block 4612, and a second magnetic plate 4613. The bracket base 4611 is disposed on the movable bracket 1, the second magnetic block 4612 is mounted on the bracket base 4611, and the second magnetic plate 4613 is fixed on the folding bracket 41. The second magnetic block 4612 can be attracted to the second magnetic plate 4613.

[0051] After the first fixing component 42 releases the fixing of the folding bracket 41 and the movable bracket 1, the assistant pushes the folding bracket 41 to rotate around the hinge point at the top of its connection with the movable bracket 1, flipping the folding bracket 41 to the side of the movable bracket 1 for storage. As the folding bracket 41 rotates, the second magnetic plate 4613 fixed to its outer side gradually approaches the second magnetic block 4612 on the side bracket seat 4611 of the movable bracket 1. When the folding bracket 41 is completely in contact with the side of the movable bracket 1, the second magnetic plate 4613 and the second magnetic block 4612... Under the action of magnetism, the second magnetic block 4612 automatically attracts the second magnetic plate 4613, and fixes the folding bracket 41 to the side of the moving bracket 1 through the magnetic attraction force, thus completing the storage and fixation. Through the stable attraction between the second magnetic block 4612 and the second magnetic plate 4613, the folding bracket 41 is fixed to the side of the moving bracket 1, thereby effectively preventing the folding bracket 41 from swinging or shaking randomly when the standing auxiliary device moves, when the ground vibrates slightly, or when people accidentally touch it, and avoiding collision between the folding bracket 41 and the moving bracket 1 or surrounding objects.

[0052] Reference Figure 10 and Figure 11 As shown: The third fixing component 46 also includes a buffer component 462, which is used to absorb the impact force when the folding bracket 41 comes into contact with the movable bracket 1.

[0053] Specifically, the buffer assembly 462 includes a buffer plate 4621 and a plurality of first guide rods 4622. The buffer plate 4621 is disposed on the side of the bracket base 4611 where the second magnetic block 4612 is mounted, and is parallel to the second magnetic block 4612. The plurality of first guide rods 4622 are arranged parallel to each other. One end of the first guide rod 4622 is connected to the buffer plate 4621, and the other end of the first guide rod 4622 is slidably connected to the bracket base 4611. Each first guide rod 4622 is fitted with a spring 4623, and the two ends of the spring 4623 abut against the buffer plate 4621 and the bracket base 4611, respectively.

[0054] When the folding bracket 41 contacts the surface of the buffer plate 4621, the rotational inertia of the folding bracket 41 causes it to exert horizontal pressure on the buffer plate 4621. After the buffer plate 4621 is subjected to force, it drives the multiple first guide rods 4622 fixed thereto to slide along the sliding holes of the bracket base 4611 towards the bracket base 4611. At the same time, it compresses the springs 4623 sleeved on the first guide rods 4622. As the springs 4623 continue to compress, the buffer plate 4621 gradually moves closer to the bracket base 4611. The magnetic force of the second magnetic block 4612 passes through the buffer plate 4621 or acts directly on the second magnetic plate 4613, so that the second magnetic plate 4613 and the second magnetic block 4612 are stably attracted. The buffer assembly 462 absorbs the inertial impact force generated by the rotation of the folding bracket 41 through the deformation of the spring 4623, thereby avoiding the second magnetic plate 4613 and the second magnetic block 4612 from colliding quickly during storage, reducing wear, paint peeling or magnetic attenuation caused by the collision.
