Description

Technical Field

[0001] The invention belongs to the field of lower limb exoskeleton rehabilitation, and in particular relates to an upper and lower machine structure and an upper and lower machine method of a lower limb rehabilitation walker. Background Art

[0002] In daily life, people often suffer from lower limb dysfunction due to polio, stroke, accidents, etc. These patients are unable to stand and walk independently and need to use lower limb exoskeletons to assist patients in walking exercises.

[0003] For people with various functional disabilities as mentioned above, their lower limbs are generally weak or even have no lower limb strength. For such people, when using the lower limb exoskeleton rehabilitation walker for training, the process of getting on the machine is a relatively big challenge for them or their assistants.

[0004] Traditional methods include: using electric lifting assist devices to help the above-mentioned people move from lying position, sitting position to standing position, such as electric transfer machines, etc., but such equipment undoubtedly increases the cost of the equipment, making the equipment not widely accessible. Summary of the invention

[0005] In order to solve the above-mentioned technical problems and use a simple method to solve the problem of users getting on and off the plane, the present invention uses a method that can ensure the safe assistance of the assistant and uses simple technical means to help user 1 safely complete the process of getting on and off the plane.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an upper and lower machine structure of a lower limb rehabilitation walker, comprising a lower limb rehabilitation walker, the lower limb rehabilitation walker having an upper and lower machine position at the rear, and also comprising a hip-supporting flexible belt worn on the user. A first connection point and a second connection point are set on the hip-supporting flexible belt; it also comprises an upper machine safety protection device and an unloading belt fixedly mounted on the lower limb rehabilitation walker; the upper machine safety protection device comprises an automatic telescopic lock, the automatic telescopic lock has a wound telescopic belt, and a control button for controlling the extension of the telescopic belt, and after pressing the control button, the telescopic belt can only retract the automatic telescopic lock, and the telescopic belt is connected to the first connection point of the hip-supporting flexible belt through a detachable structure; the unloading belt is installed at the unloading belt fixed point on the lower limb rehabilitation walker, and its end is connected to the second connection point of the hip-supporting flexible belt through a detachable structure.

[0007] In the above technical solution, one end of the retractable belt and unloading belt used is connected to the lower limb rehabilitation walker, and the other end is connected to the hip-supporting flexible belt worn by the user. The retractable belt and unloading belt generate traction on the hip-supporting flexible belt, thereby preventing the user from falling during the process of getting on and off the machine. Since the retractable belt and unloading belt can bear part of the gravity, and the caregiver can also control the retractable amount of the retractable belt and unloading belt while supporting the user, the caregiver can assist the user to get on and off the machine more easily, and can stop the operation at any time according to the situation.

[0008] As a preferred solution, a winch mechanism is provided at the fixed point of the unloading belt, and the upper end of the unloading belt is fixedly wound on the reel of the winch mechanism. Preferably, the winch mechanism is a manual operating mechanism, including a crank mechanism located on one side of the lower limb rehabilitation walker, and the crank mechanism drives the reel, so the caregiver can control the release length and speed of the unloading belt with this simple mechanical structure.

[0009] As a preferred embodiment, the hoisting mechanism has an outer shell, a stopping tooth ring is fixedly arranged at the end of the outer shell, and a series of stopping teeth are arranged on the inner ring of the stopping tooth ring; an elastic stop member is movably arranged in the stopping tooth ring, the elastic stop member is mounted on the reel and rotates synchronously with the reel; the elastic stop member has two or four stopping fingers that deviate from the main body and tilt toward the outer periphery, and a card slot is arranged on the outer side of the stopping finger; the crank mechanism is installed at the end of the reel, and an insertion shaft inserted into the card slot is arranged on the crank mechanism. When the crank mechanism is shaken, the insertion shaft squeezes the stopping finger and makes it disengage from the stopping tooth ring, and then the reel rotates. When the crank mechanism is released, the stopping finger is restored and touches the stopping tooth ring, thereby locking the crank mechanism. Through this self-locking mechanism, the safety of the unloading belt can be effectively improved to prevent user injuries caused by misoperation.

[0010] As a preferred solution, the on-machine safety protection device has two retractable belts, which are symmetrically arranged on both sides of the lower limb rehabilitation walker and respectively connected to the first connection points arranged on both sides of the hip-supporting flexible belt; the unloading belts have two sets, which are symmetrically installed at the unloading belt fixing points on both sides of the lower limb rehabilitation walker. The retractable belt and the unloading belt are symmetrically connected to the connection points on both sides of the hip-supporting flexible belt to ensure that the hip-supporting flexible belt is balanced in force, thereby ensuring that the user's body is in a stable state.

[0011] As a preferred embodiment, the hip-supporting flexible belt includes a waist belt, a right thigh belt, a left thigh belt and a hip belt, wherein the waist belt is bound to the user's waist, the right thigh belt and the left thigh belt are respectively bound to the user's thighs, and the hip belt is fixedly connected to the waist belt, the right thigh belt and the left thigh belt, and fits the user's buttocks from the back.

[0012] As a preferred solution, nursing handle belts are respectively provided on the flexible hip-supporting belt at positions corresponding to both sides of the user's waist. The nursing staff holds the nursing handle belts during the assistance process, which can better apply force and control the user's movement state.

[0013] As a preferred solution, the first connection point is located at a position corresponding to the user's thigh, and the second connection point is located at a position corresponding to the user's buttocks.

[0014] As a preferred solution, in the sitting state, the first connection point is lower than the vertical height position of the automatic telescopic lock; the second connection point is lower than the vertical height position of the unloading belt fixing point, ensuring that both the telescopic belt and the unloading belt have an upward traction effect on the user during the process of getting on and off the machine.

[0015] Based on the above-mentioned on-and-off structure, the present invention also provides an on-and-off method, which can provide safety protection for the user and enable the nursing staff to easily and quickly help the user complete the on-and-off process. The method uses the on-and-off structure of the above-mentioned lower limb rehabilitation walker and uses the hip-supporting flexible belt that is worn in advance. The specific method includes:

[0016] Steps to get started:

[0017] Step 1. The user enters the upper and lower positions behind the lower limb rehabilitation walker in a sitting position, and makes the user's knee touch the knee-top structure of the lower limb rehabilitation walker;

[0018] Step 2. Connect the releasable structure at the end of the retractable belt to the first connection point and connect it to the user;

[0019] Step 3. Press the control button of the automatic telescopic lock to automatically tighten the telescopic belt;

[0020] Step 4. The caregiver assists the user to stand up slowly, and the retractable belt automatically retracts to the automatic retractable locker as the user stands up until the user stands up;

[0021] Step 5. Bind the binding structure on the lower limb rehabilitation walker to the user to complete the process of getting on the machine;

[0022] Steps to get off the plane:

[0023] Step 1a. Place the wheelchair in the upper and lower machine positions behind the lower limb rehabilitation walker;

[0024] Step 2a. Ensure that the retractable belt is connected to the first connection point. When the user is standing, pull the unloading belt so that the releasable structure at the end thereof is connected to the second connection point of the hip-supporting flexible belt;

[0025] Step 3a. Release the binding structure of the user on the lower limb rehabilitation walker;

[0026] Step 4a. Turn the control button back so that the telescopic belt is in a free telescopic state;

[0027] Step 5a. The caregiver grasps the flexible hip support belt with one hand and the crank mechanism with the other hand, and then slowly shakes the crank mechanism to allow the user to slowly squat until he sits in the wheelchair;

[0028] Step 6a. Release the connection between the telescopic belt and the unloading belt and the hip-supporting flexible belt to complete the disembarkation process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] Figure 1 and Figure 2 Two use state diagrams of the upper and lower machine structure of the lower limb rehabilitation walker provided for the invention. The upper and lower machine structure of the lower limb rehabilitation walker includes a lower limb rehabilitation walker 15, which has an upper and lower machine position at the rear, and also includes a hip-supporting flexible belt 16 worn on the user 1. A first connection point 12 and a second connection point 14 are set on the hip-supporting flexible belt 16; it also includes an upper machine safety protection device and an unloading belt 13 fixedly installed on the lower limb rehabilitation walker 15; the upper machine safety protection device includes an automatic telescopic lock 9, the automatic telescopic lock 9 has a wound telescopic belt 11, and a control button 10 for controlling the extension of the telescopic belt 11, and after pressing the control button 10, the telescopic belt 11 can only retract the automatic telescopic lock 9, and the telescopic belt 11 is connected to the first connection point 12 of the hip-supporting flexible belt 16 through a detachable structure; the unloading belt 13 is installed at the unloading belt fixed point 130 on the lower limb rehabilitation walker 15, and its end is connected to the second connection point 14 of the hip-supporting flexible belt 16 through a detachable structure.

[0041] Specifically, a winch mechanism 131 is provided at the fixed point 130 of the unloading belt, and the upper end of the unloading belt 13 is fixedly wound on a reel 133 of the winch mechanism 131. Preferably, the winch mechanism 131 is a manual operation mechanism, including a crank mechanism located on one side of the lower limb rehabilitation walker 15. The crank mechanism 132 drives the reel 133, so that the nursing staff can control the release length and speed of the unloading belt 13 with this simple mechanical structure. Figure 3 It can be seen that the hoisting mechanism 131 has a housing 134, at the end of which a stop tooth ring 136 is fixedly arranged, and the inner ring of the stop tooth ring 136 is provided with a series of stop teeth; an elastic stopper 135 is movably arranged in the stop tooth ring 136, such as Figure 4As shown, the elastic stop member 135 is mounted on the reel 133 and rotates synchronously with the reel 133; the elastic stop member 135 has two stop fingers 138 that deviate from the main body and tilt toward the periphery. It can be seen that the ends of the stop fingers 138 are connected to the elastic brake member 135 body, and there is an avoidance space between the stop fingers 138 and the elastic brake member 135 to facilitate the elastic deformation of the stop fingers 138. In addition, a slot 139 is provided on the outer side of the stop finger 138. Figure 5 This is a structural diagram of the crank mechanism 132. It can be seen that the stop finger 138 is movably installed at the end of the reel 133 (to meet the requirement that the crank mechanism 132 can first deflect a certain angle relative to the reel 133 and then drive the reel 133 to deflect synchronously), and an insertion shaft 137 inserted into the card slot 139 is provided on the crank mechanism 132. When the crank mechanism 132 is shaken, the insertion shaft 137 squeezes the stop finger 138 and disengages it from the stop tooth ring 136, so that the reel 133 rotates. When the crank mechanism 132 is released, the stop finger 138 recovers and touches the stop tooth ring 136, thereby locking the crank mechanism 132. Through this self-locking mechanism, the safety of the unloading belt 13 can be effectively improved to prevent the user 1 from being injured due to misoperation.

[0042] like Figure 6 As shown, the hip-supporting flexible belt 16 used includes a waist belt 2, a right thigh belt 4, a left thigh belt 5 and a hip belt 3, wherein the waist belt 2 is bound to the waist of the user 1, the right thigh belt 4 and the left thigh belt 5 are respectively bound to the thighs of the user 1, and the hip belt 3 is respectively connected to the right thigh belt 4 and the left thigh belt 5 below through two triangular connecting belts 8, and is connected to the upper waist belt 2 through two symmetrically arranged waist-hip through belts 7, and the entire hip belt 3 fits the user 1 buttocks from the back; in addition, on the back of the user 1, there is a first connection point 12 arranged at a position close to the right thigh belt 4 and the left thigh belt 5, and at a position close to the buttocks, there are second connection points 14 arranged on both sides of the hip belt 3. At the same time, the machine safety protection device used has two retractable belts 11, and the two retractable belts 11 are symmetrically arranged on both sides of the lower limb rehabilitation walker 15 and are respectively connected to the first connection points 12 arranged on both sides of the hip-supporting flexible belt 16; there are also two sets of unloading belts 13, and the two sets of unloading belts 13 are symmetrically connected to the second connection points 14 arranged on both sides of the hip-supporting flexible belt 16. And from Figure 2It can be seen that in the sitting state, the first connection point 12 is lower than the vertical height position of the automatic telescopic lock 9; the second connection point 14 is lower than the vertical height position of the unloading belt fixed point 130, ensuring that the telescopic belt 11 and the unloading belt 13 both play an upward traction role on the user 1 during the process of getting on and off the machine, and the telescopic belt 11 and the unloading belt 13 on both sides provide balanced traction to the hip-supporting flexible belt 16 to prevent the user 1 from falling to one side. In order to further ensure the safety of the process of getting on and off the machine, nursing handle belts 6 are respectively provided on the hip-supporting flexible belt 16 at positions corresponding to both sides of the waist of the user 1. The nursing staff holds the nursing handle belt 6 during the assistance process, which can better apply force and control the movement state of the user 1. Of course, more nursing handle belts can be provided according to needs, for example Figure 8 As shown in the usage diagram, a nursing handle belt is provided in the middle of the waist belt 2 so that the nursing staff can lift the user 1 upwards.

[0043] Based on the above-mentioned on-and-off structure, the present invention also provides an on-and-off method, which can provide safety protection for the user 1 and enable the nursing staff to easily and quickly help the user 1 complete the on-and-off process. The method uses the on-and-off structure of the above-mentioned lower limb rehabilitation walker and uses the hip-supporting flexible belt 16 that is worn in advance. The specific method includes:

[0044] Steps to get started:

[0045] Step 1. The user 1 enters the upper and lower positions behind the lower limb rehabilitation walker 15 in a sitting position, and makes the user's knee touch the knee-top structure of the lower limb rehabilitation walker 15;

[0046] Step 2. Connect the releasable structure at the end of the retractable belt 11 to the first connection point 12 and connect it to the user 1;

[0047] Step 3. Press the control button 10 of the automatic telescopic lock 9 to automatically tighten the telescopic belt 11;

[0048] Step 4. The caregiver assists the user 1 to stand up slowly, and the retractable belt 11 automatically retracts the automatic retractable lock 9 as the user 1 stands up, until the user 1 stands up;

[0049] Step 5. Bind the binding structure on the lower limb rehabilitation walker 15 to the user 1 to complete the process of getting on the walker;

[0050] Steps to get off the plane:

[0051] Step 1a. Place the wheelchair in the upper and lower positions behind the lower limb rehabilitation walker 15;

[0052] Step 2a. Ensure that the retractable belt 11 is connected to the first connection point 12. When the user 1 is standing, pull the unloading belt 13 so that the releasable structure at the end thereof is connected to the second connection point 14 of the hip-supporting flexible belt 16;

[0053] Step 3a. Release the binding structure of the user 1 on the lower limb rehabilitation walker 15;

[0054] Step 4a. Turn back the control button 10 so that the retractable belt 11 is in a free retractable state;

[0055] Step 5a. The caregiver grasps the hip support flexible belt 16 with one hand and grasps the crank mechanism 132 with the other hand, and then slowly shakes the crank mechanism 132 to allow the user 1 to slowly squat until he sits in the wheelchair;

[0056] Step 6a. Release the connection between the retractable belt 11 and the unloading belt 13 and the hip-supporting flexible belt 16 to complete the disembarkation process.

[0057] It can be seen that the on-and-off structure of the lower limb rehabilitation walker provided by the present invention is simple and safe, does not significantly increase the complexity of the overall system, and is easy to promote on the basis of the existing lower limb exoskeleton rehabilitation walker. In the process of getting on and off the machine, it is easy for nursing staff to operate. The telescopic belt 11 and the unloading belt 13 generate traction on the hip-supporting flexible belt 16, which can effectively prevent the user 1 from falling during the process of getting on and off the machine; and because the telescopic belt 11 and the unloading belt 13 can bear part of the gravity, the nursing staff can control the telescopic amount of the telescopic belt 11 and the unloading belt 13 while supporting the user 1. Therefore, the nursing staff can more easily assist the user 1 to get on and off the machine, and can stop the operation at any time according to the situation.
