Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, specifically to a dual-power supply mode ceiling-mounted weight reduction training device. Background Technology

[0002] The health of the elderly in my country is threatened by various cerebrovascular diseases, and most patients with cerebrovascular diseases also suffer from hemiplegia or unilateral limb paralysis. Studies have shown that, in addition to drug and surgical treatments, most patients with hemiplegia or unilateral limb paralysis can regain their limb motor function through rehabilitation exercise training. Weight-loss training is currently widely used in lower limb rehabilitation. This method restores lower limb motor ability by reducing part or all of the patient's weight, helping them maintain balance, and performing weight-loss exercises.

[0003] Currently, weight-loss devices can be divided into two categories. One type uses counterweights to provide a pulling force that balances with the patient's own weight to achieve weight-loss training. Because this type of device provides a constant pulling force, the training effect is generally limited due to changes in the patient's center of gravity during rehabilitation training. The other type uses a spring mechanism to dynamically adjust the pulling force during weight-loss training, thereby improving the training effect. However, due to the limitation of the spring length, patients cannot perform large-scale walking exercises such as climbing stairs. Existing weight-loss devices are mostly frame structures. Fixed frame structures confine the patient to a fixed space, allowing them to perform weight-loss rehabilitation training only in a small area. Movable frame structures can accompany the patient during free walking training, but this type requires specific medical guidance and is larger and heavier.

[0004] However, existing technologies all rely on grid power. In the event of a sudden power outage, the device will stop working, forcing patients to stop their rehabilitation training and failing to guarantee the stability and continuity of the training.

[0005] Therefore, a dual-power supply mode overhead track weight reduction training device is needed to solve the above problems. Summary of the Invention

[0006] This invention provides a dual-power-supply-mode overhead track weight reduction training device, which is equipped with two power supply modules. When the first power supply module loses power, the second power supply module is activated in time to supply power to the entire device. When the first power supply module loses power, the second power supply circuit of the second power supply module is turned on, and the second power supply module supplies power to the first drive component and weight reduction component of the entire device. This solves the problem that in the case of a sudden power outage, the training device in the prior art will stop working, which will force the patient's rehabilitation training to stop and cannot guarantee the stability and continuity of the training.

[0053] The beneficial effects of this invention are:

[0054] 1. By setting up two power supply modules, the first power supply module's power supply, sliding contact line, current collector, and the first drive component and weight reduction component of the training device form a first power supply circuit. At the same time, the energy storage module stores the electrical energy output by the power supply. The second power supply module's battery, DC trigger, and the first drive component and weight reduction component form a second power supply circuit. The energy storage module is used to trigger the DC trigger, causing it to close. When the first power supply module loses power, the energy storage module triggers the DC trigger, causing it to close, and the second power supply circuit of the second power supply module is turned on. The second power supply module supplies power to the first drive component and weight reduction component of the entire device, thereby avoiding the forced cessation of the patient's rehabilitation training due to sudden power outages, thus ensuring the stability and continuity of the training.

[0055] 2. The driven wheel assembly of the walking component uses omnidirectional wheels, which can move along the overhead track in any direction with low friction and noise. The driven wheel base is hinged to the conductive block shell, allowing for relative rotation and relative sliding. The driven wheel assembly also has a clearance fit with the connecting assembly, which can dynamically adjust its position during turning. In addition, the horizontal guide wheel is combined to improve the stability of the walking component's movement, thereby ensuring that the training process is more in line with the actual walking process and is more conducive to assisted rehabilitation training.

[0056] 3. By setting up a charging module, when the device is located at the starting end of the ceiling track component, the conductive block contacts the telescopic conductive contact, thereby forming a charging circuit from the power supply, the telescopic conductive contact, the conductive block to the battery. This allows the battery of the second power supply module to be charged in a timely manner while the patient is performing leg raises or squats, ensuring the power supply stability of the power supply component.

[0073] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] An embodiment of the dual-power supply mode ceiling-rail weight reduction training device of the present invention, such as... Figure 1 As shown, it includes: a ceiling track assembly 1, a walking assembly 2, a first drive assembly, a weight-reducing assembly 3, and a power supply assembly; the ceiling track assembly 1 is mounted on the ceiling; the walking assembly 2 is slidably connected to the ceiling track assembly 1, and a conductive block 19 is provided on the walking assembly 2; the first drive assembly is used to drive the walking assembly 2 to move on the ceiling track assembly 1; the weight-reducing assembly 3 is located at the bottom of the walking assembly 2 and is used to assist the patient in rehabilitation training; and the power supply assembly is used to supply power to the weight-reducing assembly 3 and the first drive assembly.

[0075] The power supply components include a first power supply module, a second power supply module, and an energy storage module. The first power supply module includes a power source, a sliding contact line 17, and a current collector 15. The power source is electrically connected to the sliding contact line 17 and the current collector 15, specifically arranged along the length of the ceiling track of the ceiling track assembly 1. The conductive end of the current collector 15 contacts the sliding contact line 17 and can slide on it. The current collector 15 is electrically connected to the weight reduction component 3 and the first drive component via a wire. Specifically, the conductive end of the current collector 15 is a copper brush structure, which contacts the sliding contact line 17 through spring force, allowing the current collector 15 to slide along the sliding contact line 17. Line 17 slides relative to each other, and the end of the current collector 15 away from the copper brush is the insulating end of the insulating material. The insulating end of the current collector 15 is connected to the walking component 2. The second power supply module includes: a battery 48, which is electrically connected to the weight reduction component 3 and the first drive component through a DC contactor 47; and an energy storage module, one end of which is electrically connected to the first power supply module and the other end of which is connected to the DC trigger 47 of the second power supply module. The energy storage module is used to store the electrical energy output by the power supply when the first power supply module is working, and to close the DC trigger 47 when the first power supply module is de-energized, so that the second power supply module supplies power to the weight reduction component 3 and the first drive component.

[0076] Specifically, it also includes a charging module, which comprises a telescopic conductive contact 16 and a conductive block 19. The telescopic conductive contact 16 is disposed on the ceiling rail assembly 1, and one end of the telescopic conductive contact 16 is connected to the power supply via a wire. The conductive block 19 is disposed on the moving assembly 2, and one end of the conductive block 19 is connected to the battery 48 via a wire. The other end of the conductive block 19 is used to contact the telescopic conductive contact 16 when the moving assembly 2 is located at the starting end of the ceiling rail assembly 1, and the power output from the power supply charges the battery 48. That is, in this embodiment, after the device stops working, it moves to the starting end of the ceiling rail assembly 1, at which time the telescopic conductive contact 16 presses against the conductive block 19 to charge the battery 48.

[0077] Specifically, such as Figures 1 to 3 As shown, the ceiling track assembly 1 includes: a ceiling track, which is hollow inside and divided into an upper cavity and a lower cavity by a partition, and a slot at the bottom connecting the lower cavity; wherein, the ceiling track includes: a straight section and a curved section; a telescopic conductive contact 16 is vertically arranged in the upper cavity, and a through hole for the contact to pass through is opened on the partition below the telescopic conductive contact 16; a conductive block 19 is located in the lower cavity. It should be noted that in this embodiment, the ceiling track is laid on the ceiling, and the track type can be selected according to the patient's training needs.

[0078] Specifically, such as Figures 3 to 6As shown, the walking assembly 2 includes: a driven wheel assembly, a connecting assembly, and a driving wheel 20. The driven wheel assembly is slidably disposed in the lower cavity of the overhead track. One end of the connecting assembly passes through a slot and connects to the driven wheel assembly, while the other end of the connecting assembly connects to the mounting block 8. The driving wheel 20 is rotatably disposed in a groove opened on the top of the mounting block 8, and the outer periphery of the driving wheel 20 contacts the overhead track. The first drive assembly includes a drive motor 5, which is mounted on the support plate 9 of the housing 26 via a motor mounting bracket 21. The drive motor 5 of the first drive assembly is connected to the shaft of the driving wheel 20 via a coupling 56. Figure 5 As shown, the drive wheel 20 consists of an inner wheel and an outer wheel, which are fixed together by bolts. The first drive assembly drives the drive wheel 20 to roll at the bottom of the ceiling track, so that the walking assembly 2 moves along the ceiling track. The weight reduction assembly 3 is connected to the bottom of the mounting block 8. It should be noted that the walking assembly 2 is slidably connected to the ceiling track and is powered by the drive motor 5 of the first drive assembly to move the walking assembly 2 and the weight reduction assembly 3 along the ceiling track of the ceiling assembly 1. That is, the drive motor 5 drives the drive wheel 20 to roll at the bottom of the ceiling track, thereby driving the driven wheel assembly to slide synchronously in the lower cavity of the ceiling track through the connecting assembly.

[0079] Specifically, the driven wheel assembly includes: two driven wheel bases 12, multiple casters 11, and horizontal guide wheels 13. A conductive block housing 22 is hinged between the two driven wheel bases 12. In this embodiment, it is hinged to the driven wheel base 12 via a connecting frame 23. The conductive block 19 is disposed in a mounting groove opened on the top of the conductive block housing 22. Multiple casters 11 are evenly distributed at the bottom of the driven wheel base 12. The horizontal guide wheels 13 are disposed on the corresponding side of the driven wheel base 12, and the roller surface of the horizontal guide wheels 13 contacts the side wall of the lower cavity of the ceiling track. It should be noted that four casters 11 are disposed at the bottom of one driven wheel base 12, and two horizontal guide wheels 13 are disposed on the side. The inner bottom surface of the lower cavity of the ceiling track has grooves that cooperate with the casters 11 on two horizontal platforms symmetrical about the slot. Combined with the horizontal guide wheels 13, the walking assembly 2 will not shake during the patient's rehabilitation training, thereby ensuring the overall stability of the device. Secondly, as Figure 6As shown, the universal wheel 11 in this embodiment consists of a rubber sleeve 1101, a gasket 1102, a roller 1103, a ball bearing 1104, and a frame 1105. The universal wheel 11 is engaged with the driven wheel base 12 via a thread at the tail of the frame 1105, or via an interference fit between the frame 1105 and the driven wheel base 12. The roller 1103 is pressed into the groove of the horizontal platform in the lower cavity of the ceiling track and moves in any direction. Due to the presence of the ball bearing 1104, the friction of the universal wheel 11 during movement is relatively small. The roller 1103 is made of aluminum alloy. Alternatively, carbon steel can be used. A rubber sleeve 1101 covers the roller 1103 to reduce noise during the movement of the caster wheel 11. A gasket 1102 is installed at the bottom of the hemispherical groove of the frame 1105 to press the roller 1103 and the ball bearing 1104 into the hemispherical groove of the frame 1105. The horizontal guide wheel 13 presses against the inner walls of the lower cavity of the ceiling track to prevent the device from swinging left and right during operation, and guides the walking component 2 when it passes through the curved section of the ceiling track. In addition, in this embodiment, the conductive block shell 22 is fixedly connected by the connecting frame 23 and has openings for wires to pass through. There is an arc-shaped plate on each of the top two sides of the conductive block shell 22. The bottom of the arc surface is pressed against the upper end face of the two sets of driven mechanisms, so that the telescopic conductive contact 16 can retract smoothly along the arc surface of the arc plate during the movement, without interfering with the movement of the walking component 2 or damaging the telescopic conductive contact 16. Both ends of the connecting frame 23 have slots, which are respectively bolted to the driven mechanism with clearance, so that the driven mechanism can rotate and move relative to the conductive block housing 22 when turning, thereby improving the motion stability of the turning process.

[0080] Specifically, the connecting assembly includes: two guide seats 7, a connecting plate 10, a long screw 18, and a T-shaped slider 25. The two guide seats 7 are fixedly installed in the groove on the top of the mounting block 8. A sleeve 24 is concentrically installed on the top of the guide seats 7, and the top of the sleeve 24 passes through the groove of the overhead track and is located below the driven wheel base 12. One end of the connecting plate 10 is connected to each guide seat 7, and the other end of the connecting plate 10 passes through the groove of the overhead track and is connected between the top of the sleeve 24 and the bottom surface of the driven wheel base 12. The insulating end of the current collector 15 is connected to the side of the sleeve 24 through the current collector connecting plate 14. One end of the long screw 18 passes through the driven wheel base 12, the top of the connecting plate 10, the sleeve 24, the guide seats 7, and the mounting block 8 in sequence and is connected to the weight reduction assembly 3. It passes through a section of the guide seat 7 in a groove opened on the mounting block 8. The T-shaped slider 25 is slidably installed in the groove, and the long screw 18 is sleeved in the groove. It should be noted that, in this embodiment, by tightening the nut at the bottom of the long screw 18, the driving wheel 20 is pressed against the lower end face of the ceiling track, preventing the driving wheel 20 from slipping during movement. The top of the connecting plate 10 is pressed against the lower end face of the driven wheel base 12 by a shim. Adjusting the preload of the connecting plate 10 on the shim can adjust the pressing effect of the driving wheel 20, improving the movement stability of the walking assembly 2. Secondly, the diameters of the openings at the top of the guide seat 7, the connecting plate 10, and the driven wheel base 12 are larger than the diameter of the long screw 18. Therefore, the guide seat 7 and the connecting plate 10 of the walking assembly 2 can rotate relative to the driven wheel assembly during movement, ensuring the turning of the weight-reducing assembly 3 at the curve of the ceiling track. Furthermore, when rehabilitation training is performed, due to the change in the patient's center of gravity, the weight-reducing assembly 3 will bear loads in the horizontal and vertical directions. The T-shaped slider 25 can limit the vertical and horizontal swaying of the weight-reducing assembly 3, increasing the stability of the device.

[0081] Specifically, such as Figures 7 to 9As shown, the weight-reducing component 3 includes: a housing 26, a drum 34, a sling 33, and a guide rail 42. The housing 26 is located at the bottom of the mounting block 8. The drum 34 is rotatably mounted on one side of the housing 26. One end of the sling 33 is connected to the drum 34, and the other end of the sling 33 passes through the housing 26 and is guided by the guide wheel assembly and the fixed pulley 46 before exiting vertically downward from the bottom of the housing 26. The end of the sling 33 that exits from the bottom of the housing 26 is used for suspension support of the lower limbs of the human body. The guide rail 42 is horizontally mounted between the inner walls of the housing 26. A movable plate 44 is slidably mounted on the guide rail 42. A reset assembly is provided between the side of the movable plate 44 facing the drum 34 and the inner wall of the housing 26. The reset assembly uses a compression spring 41. A set is mounted on guide rail 42, wherein a fixed pulley 46 is mounted on movable plate 44; the second drive component is a weight-reducing motor 31, which drives drum 34 to rotate, so that sling 33 moves up and down after being guided by guide wheel assembly and fixed pulley 46, to assist patients in rehabilitation training. Specifically, guide wheel assembly includes: first guide wheel 36, second guide wheel 37 and third guide wheel 40, and the first guide wheel 36, second guide wheel 37 and third guide wheel 40 are all rotatably mounted in housing 26 by bracket; wherein, after sling 33 enters housing 26, it is guided by first guide wheel 36, first guide wheel 37, fixed pulley 46 and third guide wheel 40 in sequence, and then exits vertically downward from the bottom of housing 26; Figure 9 As shown, the first guide wheel 36 is arranged corresponding to the side opening of the outer casing 26, and its bottom side is flush with the bottom side of the drum 34, used to press the sling 33; the second guide wheel 37 is flush with the center of the fixed pulley 46; the third guide wheel 40 is arranged corresponding to the opening on the outer casing 26, and the top side of the third guide wheel 40 is flush with the bottom side of the fixed pulley 46. The sling 33 is pressed by the first guide wheel 36, turns 180° after passing the fixed pulley 46, turns 90° after passing the third guide wheel 40, and finally hangs vertically downward.

[0082] It should be noted that in this embodiment, the outer shell 26 includes a shell with a top opening, which is connected by a support plate 9. The guide rail 42 is fixed to the outer shell 26 at both ends by flanges. The movable plate 44 is mounted on the guide rail 42 by a linear bearing 43 and can slide relative to the guide rail 42. The compression spring 41 is sleeved on the guide rail 42, with one end of the compression spring 41 contacting the movable plate 44 and the other end of the compression spring 41 contacting the inner wall of the outer shell 26. The two guide rails 42 are parallel to each other and pass through the movable plate 44, and there are also two corresponding compression springs 41 and linear bearings 43. The weight reduction motor 32 is fixed to the housing 26 by a weight reduction motor mounting plate 31, and the output of the weight reduction motor 32 is... The shaft is connected to one end of the drum 34, and the other end of the drum 34 is installed in the bearing seat 35 through a bearing. The end of the sling 33 is looped, and the sling 33 is wound around the drum 34 with the loop end fitted onto the stop pin on the drum 34 to ensure that the sling 33 is always wrapped around the drum 34 during the patient's training, so as to ensure the safety of the weight loss training. The other end of the sling 33 passes through the opening of the housing 26, is guided by the first guide wheel 36, the second guide wheel 37, the fixed pulley 46 and the third guide wheel 40, and then passes out through the opening of the housing 26 to drive the patient to carry out weight loss rehabilitation training. The weight loss component 3 is located below the walking component 2 and is equipped with a sling 33. The sling 33 is connected to the patient and drives the patient to carry out weight loss training.

[0083] Specifically, it also includes a detection module, which comprises a tension sensor 45, an angle sensor 38, and a control module. The tension sensor 45 is used to detect the tension force on the sling 33; the angle sensor 38 is used to detect the tilt angle of the sling 33 in the vertical direction. Specifically, for example... Figure 9 As shown, the angle sensor 38 is mounted on the bottom of the housing 26 of the weight reduction unit 3 via the angle sensor mounting base 39; the control module is used to control the extension and retraction of the sling 33 in the weight reduction assembly 3 according to the detected tension; and to control the moving speed of the walking assembly 2 according to the detected tilt angle. The control module includes a controller 49, a signal conversion module, a Bluetooth module, and a voice broadcast module. The controller 49 communicates with the mobile phone operating terminal via the Bluetooth module, such as... Figure 8As shown, the control module is housed within the outer casing 26. The fixed pulley 46 is connected to the movable plate 44 via a tension sensor. It should be noted that the angle sensor 38 is mounted on the bottom of the weight-reducing component 3 via an angle sensor mounting base 39, used to detect the tilt angle of the sling 33 during rehabilitation training. The tilt angle data can be used as an input signal in the patient's active training mode to control the movement speed of the walking component 2, thereby adjusting the speed of the patient's horizontal movement in the active training mode. The tension sensor 45 is mounted on the movable plate 44 to detect the tension force on the sling 33. The tension data detected by the tension sensor 45 is used as an input signal to control the weight-reducing motor 32 to extend and retract the sling 33, thereby achieving vertical movement for the patient. The adjustment of the weight reduction force; at the same time, if the patient accidentally falls during training, the tension data measured by the tension sensor 45 will increase rapidly, and the controller 49 will send relevant instructions to immediately stop the training to avoid secondary injury to the patient. This embodiment also includes: two photoelectric sensors 30, which are symmetrically installed on both sides of the support plate 9 through photoelectric sensor mounting base 29, for detecting obstacles in front of and behind the ceiling track assembly 1 to prevent the device from colliding; the controller 49 of the control module is connected to the current collector 15, the weight reduction motor driver 27 of the weight reduction motor 32, the drive motor driver 28 of the drive motor 5, the DC contactor 47, and the battery 48, wherein the battery 48 is selected as a lithium battery or a storage battery.

[0084] Specifically, it also includes a locking assembly for locking the coupling 56 when the contact end of the telescopic conductive contact 16 contacts the conductive block 19; wherein, for example Figure 11 As shown, the brake assembly includes: a mounting base 6, two arc-shaped brake pads 55, and a third drive assembly; the mounting base 6 is located on the top of the housing 26, wherein the shaft of the drive wheel 20 passes through the mounting base 6 and is connected to the coupling 56; the two arc-shaped brake pads 55 are evenly distributed around the coupling 56, with the inner ring of the arc-shaped brake pads 55 facing the coupling 56, one end of each arc-shaped brake pad 55 is rotatably connected to the mounting base 6, and the rotating ends of the two arc-shaped brake pads 55 are opposite to each other; one arc-shaped brake pad 55 is connected to an active pressure rod 53 via a tension spring 54, and the active pressure rod 53 is slidably connected to the mounting base 6 in the vertical direction; the other arc-shaped brake pad 55 is connected to a driven pressure rod 50 via a tension spring 54, as shown in the figure. Figure 11As shown, the mounting base has an elongated hole. The middle part of the driven pressure rod 50 is rotatably and slidably connected to the elongated hole of the mounting base 6 through a connecting post, and the end of the driven pressure rod 50 is hinged to the active pressure rod 53. The third drive assembly is used to drive the active pressure rod 53 to slide in the vertical direction, so as to drive the two arc-shaped brake pads 55 to fit against and lock the coupling 56 to the outer periphery. It should be noted that in this embodiment, one side of the mounting base 6 is fixedly connected to the motor mounting bracket 21; the active pressure rod 53 is installed on the other side. A slot is opened in the middle of the active pressure rod 53. The gravity compensation spring 51 is installed in the slot through the guide block 52, and one end of the guide block 52 is fixed to the mounting base 6. The driven pressure rod 50 is rotatably and slidably connected to the elongated hole of the mounting base 6 through the connecting post located on it, and one end of the driven pressure rod 50 is rotatably connected to the active pressure rod 53. There are two tension springs 54 and two arc-shaped brake pads 55. One end of each tension spring 54 is connected to the active pressure rod 53 and the driven pressure rod 50, respectively, and the other end is connected to the end of the arc-shaped brake pad 55. When the device is in operation, the gravity compensation spring 51 and the tension springs 54 are compressed, and their elastic force balances the weight of the active pressure rod 53, the driven pressure rod 50, and the brake pad 55, causing the brake pad 55 to disengage from the coupling 56. When the device is charging, the active pressure rod 53 is subjected to the clamping force of the third drive assembly and moves downward, driving the driven pressure rod 50 to move and rotate along the slot, thereby stretching both tension springs 54. The pressure generated by the tension springs 54 presses the brake pad 55, thereby pressing the coupling 56 to brake the drive motor 4.

[0085] It should be noted that: such as Figure 10 As shown, the third drive assembly in this embodiment includes: a pressure rod sleeve 4, a rubber sleeve 57, a pressure rod 58, a stop pin 59, a pressure rod spring 60, a pull rope hook 61, a fixing pin 62, and a pressure rod mounting base 63. One end of the pressure rod mounting base 63 is mounted on the ceiling rail assembly 1, and the other end is fixedly connected to the pressure rod sleeve 4. The pressure rod 58 has a slot, with the fixing pin 62 located at the top of the slot and the stop pin 59 located at the bottom of the slot. The pressure rod 58 is mounted on the pressure rod sleeve 4 via the stop pin 59 and the fixing pin 62, and its bottom end is fixedly connected to the rubber sleeve 57. The stop pin 59 presses against the pressure rod spring 60 and is fixedly connected to the pull rope hook 61. When the device is in operation, the pull rope is fixed at a certain position and always remains taut, and the stop pin 59 always presses against the pressure rod spring 60. At this time, the pressure rod 58 is only constrained by the fixing pin 62, so it can move up and down, and the third drive mechanism has no clamping force on the locking assembly. When the device is charging, the pull rope is loosened, and the stop pin 59 is pressed into the groove of the pressure rod 58 by the pressure rod spring 60; at this time, the pressure rod 58 is fully constrained by the stop pin 59 and the fixing pin 62, and the rubber sleeve 57 provides locking force to the locking assembly; by pulling the pull rope connected to the pull rope hook 61, the position of the stop pin 59 is changed, so that the third drive assembly presses or releases the locking assembly.

[0086] It should be noted that, as Figure 12 and Figure 13 As shown, the sliding contact line 17 is connected to the power supply and supplies power to the current collector 15. The current collector 15 serves as the positive and negative terminals of the battery and is connected to the energy storage element (a capacitor in this embodiment), the weight reduction motor driver 27, the drive motor driver 28, and the controller 49. It also directly supplies power to the photoelectric sensor 30, the angle sensor 38, and the tension sensor 45, thus forming the first power supply circuit of the first power supply module. The positive and negative terminals of the battery 48 are connected to the DC contactor 47, the weight reduction motor driver 27, the drive motor driver 28, and the controller 49, and directly supply power to the photoelectric sensor 30, the angle sensor 38, and the tension sensor 45. This connects the DC contactor 47 to the energy storage element of the first power supply circuit, thus forming the second power supply circuit of the second power supply module. The electrical circuit controls the drive motor driver 28 and the weight reduction motor driver 27 via the controller 49, enabling the drive motor 5 and the weight reduction motor 32 to operate. The tension sensor 45 and the angle sensor 38 feed back the patient training data to the controller 49. Under normal operating conditions, the power supply supplies power to the current collector 15 of the first power supply circuit through the sliding contact line 17. The current collector 15 conducts electricity to the device as the positive and negative terminals of the power supply. When the power supply is suddenly disconnected, the first power supply circuit of the first power supply module will be disconnected. The energy storage element located in the first power supply circuit supplies power to the DC contactor 47. The switch of the DC contactor 47 is closed, the second power supply circuit of the second power supply module is turned on, and the device is switched to be powered by the battery 48 of the second power supply module.

[0087] Specific working principle

[0088] like Figure 14As shown, when the weight loss rehabilitation training begins, the power switch is turned on, and the sliding contact line 17 supplies power to the weight loss training device through the current collector 15; the walking component 2 drives the weight loss training device to move along the ceiling track component 1; when the walking component 2 moves on the straight section of the ceiling track, the drive motor 5 drives the drive wheel 20 to roll at the bottom of the ceiling track. Since the sling 33 is loaded, the device is subjected to a vertical downward force. By tightening the nut at the bottom of the long screw 18, the drive wheel 20 presses against the lower end face of the ceiling track. During this process, the horizontal guide wheel 13 located on the driven wheel base 12 always presses against the inner side walls of the lower cavity of the ceiling track, and together with the connecting plate 10, ensures the horizontal stability of the patient during weight loss training; when the walking component 2 enters the curved section of the ceiling track, the horizontal guide wheel 13 guides the universal wheel 11 to move along the groove of the horizontal part at the bottom of the ceiling track; the long screw 18 and the driven wheel base 12 are in clearance fit, which allows the drive mechanism and the driven mechanism to rotate relative to each other; the two driven mechanisms are connected to the connecting frame 23 through slots, and the relative positions of the two driven mechanisms can be adjusted as needed, thereby achieving weight loss. The weight training device moves along the curved section of the overhead track; the weight reduction component 3 provides a weight reduction force aligned with the direction of the patient's lower limb support force. The magnitude of the weight reduction force is equal to the patient's own weight minus the support force of the patient's lower limbs, and its value can be adjusted autonomously; the weight reduction motor 32 drives the drum 34 to tighten the sling 33 and suspend the patient for weight reduction training. At this time, the compression spring 41 is compressed due to the tension of the sling 33; when the patient walks and lowers their foot or squats, the center of gravity of the body moves downward, the tension of the sling 33 increases, the compression spring 41 is further compressed, and the movable plate 44 moves towards the patient. At this time, the weight reduction motor 32 relaxes the sling 33, restoring the tension to the set value. When the patient walks and lifts their foot or stands up, the center of gravity of the body moves upward, the tension of the sling 33 decreases, the compression spring 41 extends, and the movable plate 44 moves away from the patient. At this time, the weight reduction motor 32 tightens the sling 33, restoring the tension to the set value. During patient movement, the tension sensor 45 measures the tension on the sling 33 and controls the weight-reducing motor 32 via the controller 49 to dynamically adjust the sling 33. If the patient accidentally falls or becomes too weak to support themselves, the tension sensor 45 detects a rapid increase in the tension on the sling 33. At this point, the weight-reducing motor 32 immediately stops working to prevent secondary injury to the patient.

[0089] When a power outage occurs during weight-loss rehabilitation training, i.e., the power supply to the first power supply module fails, the drive motor 5 and the weight-loss motor 32 will immediately stop working by engaging the brakes. The energy storage element in the first power supply circuit of the first power supply module supplies power to the DC contactor 47, thus enabling the second power supply circuit of the second power supply module to conduct. The battery 48 of the second power supply module will continuously supply power to the drive motor 5, the weight-loss motor 32, the photoelectric sensor 30, the angle sensor 38, the tension sensor 45, and the controller 49, allowing the weight-loss training device to continue weight-loss training for a short period. After the weight-loss rehabilitation training is completed, the device returns to the position of the telescopic conductive contact 16 on the overhead track. When the device approaches the telescopic conductive contact 16, the pressure rod 58 of the third drive component presses the brake pad 55 to stop the device. The telescopic conductive contact 16 presses the conductive block 19 and charges the battery 48 through the wire.
