Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation exercise, and in particular to a rehabilitation exercise device for pregnant women after childbirth. Background Art

[0002] After giving birth, pregnant women may face problems such as pelvic floor muscle injury, rectus abdominis separation, poor uterine recovery, and low back pain. Rehabilitation exercises can help repair these injuries, promote physical recovery, improve mental health, and prevent long-term health problems.

[0003] At present, postpartum rehabilitation exercises mainly include pelvic floor muscle exercises, rectus abdominis separation repair, core muscle exercises, etc., among which rectus abdominis separation repair includes supine, knee flexion, leg opening and closing, etc. As pregnant women are relatively weak after giving birth, they usually use rehabilitation exercise devices for passive exercise, but most existing rehabilitation exercise devices have simple structures and can usually only perform rehabilitation exercises of a single action, and the rehabilitation exercise effect is poor. Therefore, in view of the above technical problems, a postpartum rehabilitation exercise device for pregnant women is proposed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a postpartum rehabilitation exercise device for pregnant women, which can perform leg opening and closing and knee flexion exercises at the same time, thereby improving the rehabilitation exercise effect.

[0035] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0036] See also Figure 1 , Figure 2 and Figure 6 In one embodiment, a postpartum rehabilitation exercise device for pregnant women includes a bed board 10, a first exercise mechanism and a second exercise mechanism.

[0037] Among them, the first exercise mechanism includes a mounting plate 20 and a driving mechanism. The mounting plate 20 is rotatably arranged at one end of the bed board 10, and two groups are symmetrically arranged. The driving mechanism is arranged on the bed board 10, and is used to drive the two groups of mounting plates 20 to open or close and swing.

[0038] The second exercise mechanism includes a support assembly and a first transmission mechanism. The two groups of mounting plates 20 are both provided with support assemblies. The support assembly includes a first support plate 30 and a second support plate 301. One end of the first support plate 30 is hinged to one end of the mounting plate 20, and the other end is hinged to one end of the second support plate 301. The other end of the second support plate 301 is hinged to a limit seat 302. The limit seat 302 is slidably arranged at the other end of the mounting plate 20 along the length direction of the mounting plate 20. Specifically, a T-shaped slide groove 206 is provided on the mounting plate 20, and a T-shaped slider is provided at the bottom end of the limit seat 302. The T-shaped slider is slidably arranged in the T-shaped slide groove 206 along the length direction of the mounting plate 20. The first transmission mechanism connects the bed board 10, the two groups of mounting plates 20 and the two groups of first support plates 30, so as to convert the outward opening or closing swing of the two groups of mounting plates 20 into the closing or outward opening swing of the first support plate 30 and the second support plate 301.

[0039] In the above embodiment, during exercise, the user lies on the bed board 10 and places the thigh and calf on the first support plate 30 and the second support plate 301 respectively, and then starts the driving mechanism to drive the two groups of mounting plates 20 to open or close and swing. The two groups of mounting plates 20 can drive the legs to perform opening and closing movements through the first support plate 30 and the second support plate 301. At the same time, the first transmission mechanism converts the outward expansion or closing swing of the two groups of mounting plates 20 into the closing or outward expansion swing of the first support plate 30 and the second support plate 301. The closing or outward expansion swing of the first support plate 30 and the second support plate 301 can drive the legs to perform knee flexion movements, so that the legs can perform knee flexion movements while performing opening and closing movements, thereby improving the rehabilitation exercise effect, and there is no need to separately drive the first support plate 30 and the second support plate 301 to close or open and swing, thereby reducing the use cost and improving the practicality of the device.

[0040] Specifically in the above embodiment, both sides of the first support plate 30 and the second support plate 301 are correspondingly provided with fixing belts 50. In the corresponding two groups of fixing belts 50, one group of fixing belts 50 is provided with a Velcro fleece surface on the outside, and the other group of fixing belts 50 is provided with a Velcro hook surface on the inside. The thigh and calf can be limited by passing the corresponding fixing belts 50 around the thigh and calf and bonding them through the Velcro fleece surface and the Velcro hook surface, thereby preventing the legs from falling off the first support plate 30 and the second support plate 301 during exercise, thereby improving the stability during exercise.

[0041] See also Figures 1 to 3 and Figure 5 In one embodiment, the driving mechanism includes a guide rod 201, a gear 202, a rack 203 and a first driving assembly; the guide rod 201 can be slidably arranged at the bottom of the bed board 10 along the width direction of the bed board 10. Specifically, two sets of guide shafts 101 are relatively arranged at the bottom of the bed board 10, and the two ends of the guide rod 201 can be slidably sleeved on the two sets of guide shafts 101 along the width direction of the bed board 10. The bottom ends of the rotating shafts of the two sets of mounting plates 20 are coaxially arranged with gears 202, and racks 203 are relatively arranged on both sides of the guide rod 201. The two sets of racks 203 are respectively meshed with the two sets of gears 202. The driving assembly is arranged on the bed board 10 to drive the guide rod 201 to move back and forth.

[0042] In the above embodiment, the guide rod 201 is driven to move back and forth by the driving component, driving the two sets of racks 203 to move back and forth. The reciprocating movement of the two sets of racks 203 and the engagement with the two sets of gears 202 can drive the two sets of gears 202 to rotate back and forth in the opposite directions. The reciprocating rotation of the two sets of gears 202 can drive the two sets of mounting plates 20 to swing outward or close. It is convenient to drive the two sets of mounting plates 20 to swing outward or close, which is convenient for opening and closing movements of the legs.

[0043] See also Figure 3 and Figure 5 In one embodiment, the first driving assembly includes a motor 204 and a turntable 205; the motor 204 is fixed at the bottom of the bed board 10, the output shaft of the motor 204 is coaxially connected to the turntable 205, a first shifting shaft 2051 is eccentrically arranged at the top of the turntable 205, a first shifting groove 2011 is opened on the guide rod 201, and the first shifting shaft 2051 is slidably arranged in the first shifting groove 2011.

[0044] In the above embodiment, the motor 204 is started to drive the turntable 205 to rotate. The turntable 205 rotates to drive the guide rod 201 to move back and forth through the cooperation of the first shift shaft 2051 and the first shift groove 2011. It is convenient to drive the guide rod 201 to move back and forth, and by converting the unidirectional rotation of the motor 204 into the reciprocating movement of the guide rod 201, the control is simple and the operation is convenient.

[0045] See also Figure 1 , Figure 2and Figure 6 In one embodiment, the first transmission mechanism includes a first screw rod 303, a slider 304, a first support rod 305 and a first transmission assembly; the first screw rod 303 is rotatably provided on both sets of mounting plates 20, and the rotation directions of the two sets of first screw rods 303 are opposite. The sliders 304 are slidably provided along the length direction of the two sets of mounting plates 20. Specifically, the two sets of mounting plates 20 are provided with guide grooves 207, and the sliders 304 are slidably provided in the guide grooves 207 along the length direction of the mounting plates 20. The first screw rods 303 are respectively threadedly connected to the two groups of sliders 304, and the two groups of sliders 304 are hinged with first support rods 305. One ends of the two groups of first support rods 305 are respectively hinged to the two groups of first support plates 30. The first transmission assembly is arranged on the bed board 10 and connected to the two groups of first screw rods 303, so as to convert the outward opening or closing swing of the two groups of mounting plates 20 into the opposite rotation of the two groups of first screw rods 303, so as to drive the first support plate 30 and the second support plate 301 to close or swing outward.

[0046] In the above embodiment, when the two groups of mounting plates 20 swing outwards, the two groups of first screw rods 303 are driven to rotate in opposite directions through the first transmission assembly. Since the two groups of first screw rods 303 rotate in opposite directions, the two groups of first screw rods 303 rotate in opposite directions and cooperate with the two groups of sliders 304 to drive the two groups of sliders 304 to move and drive the first support plate 30 to swing through the first support rod 305. The swing of the first support plate 30 can drive the second support plate 301 to swing, so that the first support plate 30 and the second support plate 301 are closed and swung. When the two groups of mounting plates 20 are closed and swung, the two groups of first screw rods 303 are driven to rotate in opposite directions through the first transmission assembly. When a screw rod 303 rotates in the opposite direction, the two groups of first screw rods 303 rotate in the opposite direction and cooperate with the two groups of sliders 304 to drive the two groups of sliders 304 to move in the opposite direction and drive the first support plate 30 to swing in the opposite direction through the first support rod 305. The reverse swing of the first support plate 30 can drive the second support plate 301 to swing in the opposite direction, so that the first support plate 30 and the second support plate 301 can be swung outward and reset, and it is convenient to drive the first support plate 30 and the second support plate 301 to close or swing outward, so that it is convenient for the first support plate 30 and the second support plate 301 to drive the legs to perform knee flexion exercise.

[0047] See also Figure 1 , Figure 2 and Figure 6 In one embodiment, the first transmission assembly includes a bevel gear 306 and a bevel gear ring segment 307; two sets of bevel gear ring segments 307 are arranged opposite to each other on the bed plate 10, and the two sets of bevel gears 306 are respectively meshed with the two sets of bevel gear ring segments 307.

[0048] In the above embodiment, the outward swing of the two groups of mounting plates 20 can drive the outward swing of the two groups of first screws 303, and the outward swing of the two groups of first screws 303 can drive the two groups of first screws 303 to rotate in opposite directions through the engagement of the bevel gear 306 and the bevel gear ring segment 307. Conversely, the closing and swinging of the two groups of mounting plates 20 can drive the two groups of first screws 303 to close and swing, and the closing and swinging of the two groups of first screws 303 can drive the two groups of first screws 303 to rotate in opposite directions through the engagement of the bevel gear 306 and the bevel gear ring segment 307. This facilitates the conversion of the outward expansion or closing swing of the two groups of mounting plates 20 into the opposite rotation of the two groups of first screws 303, and there is no need to set up a separate power device to drive the first screws 303 to rotate, thereby saving energy, reducing the cost of using the device, and improving the practicality of the device.

[0049] See also Figure 1 , Figure 2 , Figure 4 and Figure 6 In one embodiment, the first transmission assembly further includes a lifting assembly, which includes a mounting block 308 and a second screw 309. The mounting block 308 is slidably disposed at the top of the bed board 10 in a vertical direction. Both ends of the mounting block 308 are fixed with bevel gear ring segments 307. The second screw 309 is vertically rotatably disposed on the bed board 10 and is threadedly connected to the mounting block 308. Specifically, a first slide groove 102 is provided at the top of the bed board 10, and two groups of clearance grooves 103 communicating with the first slide groove 102 are provided corresponding to the two groups of bevel gear ring segments 307. The mounting block 308 and the bevel gear ring segment 307 are respectively slidably disposed in the first slide groove 102 and the clearance groove 103 in a vertical direction.

[0050] In the above embodiment, the mounting block 308 is driven downward by rotating the second screw 309 and the mounting block 308 threadedly cooperate to drive the mounting block 308 to move downward, and the mounting block 308 moves downward to drive the two sets of bevel gear ring segments 307 to move downward, and the two sets of bevel gear ring segments 307 move downward to separate from the two sets of bevel gears 306. At this time, the outward expansion or closing swing of the two sets of mounting plates 20 will not drive the first screw 303 to rotate, so that only the opening and closing movement of the legs is performed, and the second screw 309 is driven upward by rotating the second screw 309 and the mounting block 308 threadedly cooperate to drive the mounting block 308 to move upward, and the mounting block 308 moves upward to drive the two sets of bevel gear ring segments 307 to move upward, and the two sets of bevel gear ring segments 307 move upward to separate from the two sets of bevel gears 306, thereby performing the opening and closing movement of the legs and the knee flexion movement synchronously, which is convenient for selection according to user needs and improves the practicality of the device. It can be understood that when the first support plate 30 and the second support plate 301 are in the extended state, the legs can be placed straight on the first support plate 30 and the second support plate 301, at this time, the bevel gear ring segment 307 is separated from the bevel gear 306, and the legs can be opened and closed when the legs are straight. When the first support plate 30 and the second support plate 301 are in the closed state, the legs are placed on the first support plate 30 and the second support plate 301 in a bent knee state. At this time, the bevel gear ring segment 307 and the bevel gear 306 are separated. When the gear 306 is separated, the leg can be kept in a bent knee state to perform leg opening and closing movements, which is convenient for the leg to be in a straight state or a bent knee state to perform leg opening and closing movements, further improving the practicality of the device. It can be understood that when the bevel gear ring segment 307 and the bevel gear 306 are separated and meshed again, the meshing position of the bevel gear ring segment 307 and the bevel gear 306 should remain consistent with that before separation, and the bevel gear ring segment 307 and the bevel gear 306 can be separated or meshed at the extreme position of the two sets of mounting plates 20 being opened or closed.

[0051] See also Figure 1 and Figure 2 In one embodiment, a third exercise mechanism is further included, and the third exercise mechanism includes a back plate 40 and a second transmission mechanism. The back plate 40 is hinged at the other end of the bed board 10. The second transmission mechanism is arranged on the bed board 10 and connects the back plate 40 and the two sets of mounting plates 20 to convert the outward opening or closing swing of the two sets of mounting plates 20 into the opening or closing rotation of the back plate 40 relative to the bed board 10.

[0052] In the above embodiment, when the two groups of mounting plates 20 swing outward, the second transmission mechanism converts the outward swing of the two groups of mounting plates 20 into the opening and rotation of the back plate 40 relative to the bed plate 10. The opening and rotation of the back plate 40 relative to the bed plate 10 can support the user's back to stand up. When the two groups of mounting plates 20 swing together, the second transmission mechanism converts the closing and swinging of the two groups of mounting plates 20 into the closing and rotation of the back plate 40 relative to the bed plate 10. The closing and rotation of the back plate 40 relative to the bed plate 10 can cancel the support for the user's back, so that the user can lie down, thereby facilitating the standing up exercise while doing the leg opening and closing exercise, facilitating the exercise of the rectus abdominis muscle, further improving the effect of rehabilitation exercise, and there is no need to drive the back plate 40 to rotate separately, thereby reducing the use cost and improving the practicality of the device.

[0053] See also Figure 1 , Figure 2 , Figure 4 and Figure 7 In one embodiment, the second transmission mechanism includes a driving rod 401, a second support rod 402 and a second transmission assembly; the driving rod 401 can be slidably arranged on the bed board 10 along the length direction of the bed board 10, one end of the driving rod 401 is hinged to the second support rod 402, one end of the second support rod 402 is hinged to the bed board 10, and the second transmission assembly connects the driving rod 401 and the two sets of mounting plates 20 to convert the outward opening or closing swing of the two sets of mounting plates 20 into the reciprocating movement of the driving rod 401. Specifically, the top of the bed board 10 is provided with a second slide groove 104 and a third slide groove 105, the driving rod 401 is slidably arranged in the second slide groove 104 and the third slide groove 105 along the length direction of the bed board 10, and the end of the driving rod 401 located in the third slide groove 105 is hinged to the second support rod 402.

[0054] In the above embodiment, when the two groups of mounting plates 20 are swung outward, the second transmission assembly moves the driving rod 401, and the driving rod 401 moves through the second support rod 402 to drive the back plate 40 to open and rotate relative to the bed board 10. When the two groups of mounting plates 20 are swung together, the second transmission assembly moves the driving rod 401 in the opposite direction, and the driving rod 401 moves in the opposite direction to drive the back plate 40 to close and rotate relative to the bed board 10 through the second support rod 402, so that the back plate 40 can be driven to open or close and rotate relative to the bed board 10 conveniently.

[0055] See also Figure 1 , Figure 2 and Figure 7In one embodiment, the second transmission assembly includes a sliding seat 403; the sliding seat 403 is fixed at the other end of the driving rod 401. Specifically, the sliding seat 403 is fixed at the end of the driving rod 401 located at the second slide groove 104. Second shift shafts 404 are provided on both sides of the sliding seat 403. Second shift grooves 405 are provided on opposite sides of the two groups of mounting plates 20. The two groups of second shift grooves 405 are matched to form a V shape, and the two groups of second shift shafts 404 are respectively slidably set in the two groups of second shift grooves 405.

[0056] In the above embodiment, the outward swing of the two groups of mounting plates 20 can drive the sliding seat 403 to drive the driving rod 401 to move by cooperating with the two groups of second shift grooves 405 and the two groups of second shift shafts 404. The closing swing of the two groups of mounting plates 20 can drive the sliding seat 403 to drive the driving rod 401 to move in the opposite direction by cooperating with the two groups of second shift grooves 405 and the two groups of second shift shafts 404, so as to convert the outward expansion and closing swing of the two groups of mounting plates 20 into the reciprocating movement of the driving rod 401.

[0057] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 In one embodiment, a mounting groove 406 is provided on the top surface of the back plate 40, and a plurality of massage rollers 407 are rotatably arranged in the mounting groove 406, and the axes of the plurality of massage rollers 407 are parallel to the width direction of the bed board 10. The top surface of the back plate 40 is covered with a cover plate 408 that can seal the opening of the mounting groove 406, and the top surface of the cover plate 408 is flush with the top surface of the back plate 40.

[0058] In the above embodiment, by removing the cover plate 408, when the user lies on the backboard 40, the back can contact the multiple groups of massage rollers 407. It can be understood that when the backboard 40 rotates, the backboard 40 and the back will have some relative displacement. When the backboard 40 and the back are relatively displaced, the contact friction between the multiple groups of massage rollers 407 and the back can cause the multiple groups of massage rollers 407 to rotate, thereby achieving the purpose of massaging the back while doing standing exercises, further improving the effect of rehabilitation exercises. If there is no need to massage the back, the cover plate 408 can be reset, which is convenient for users to choose according to their own needs, thereby improving the practicality of the device.

[0060] By lying on the backboard 40 with the thighs and calves respectively placed on the first support board 30 and the second support board 301, during exercise, the motor 204 is started to drive the turntable 205 to rotate, and the rotation of the turntable 205 can drive the guide rod 201 to move back and forth through the first shifting shaft 2051 and the first shifting groove 2011. The reciprocating movement of the guide rod 201 drives the two sets of racks 203 to move back and forth, and the reciprocating movement of the two sets of racks 203 and the engagement of the two sets of gears 202 can drive the two sets of gears 202 to rotate back and forth in the opposite direction. The opposite reciprocating rotation of the two sets of gears 202 can drive the two sets of mounting plates 20 to swing outward or close, and the two sets of mounting plates 20 swing outward or close can drive the legs to do opening and closing movements through the first support board 30 and the second support board 301.

[0061] At the same time, the two groups of mounting plates 20 swing outwards and drive the two groups of first screws 303 to rotate in opposite directions through the meshing of the bevel gear 306 and the bevel gear ring segment 307. The two groups of first screws 303 rotate in opposite directions and cooperate with the threads of the two groups of sliders 304 to drive the two groups of sliders 304 to move and drive the first support plate 30 to swing through the first support rod 305. The swing of the first support plate 30 can drive the second support plate 301 to swing, so that the first support plate 30 and the second support plate 301 are closed and swung. The closing and swinging of the two groups of mounting plates 20 are connected through the bevel gear 306 and When the bevel gear ring segment 307 engages to drive the two groups of first screw rods 303 to rotate in opposite directions, the two groups of first screw rods 303 rotate in opposite directions and cooperate with the threads of the two groups of sliders 304 to drive the two groups of sliders 304 to move in opposite directions and drive the first support plate 30 to swing in the opposite direction through the first support rod 305. The reverse swing of the first support plate 30 can drive the second support plate 301 to swing in the opposite direction, so that the first support plate 30 and the second support plate 301 are swung outward and reset, so that the first support plate 30 and the second support plate 301 drive the legs to perform knee flexion exercise.

[0062] At the same time, the two groups of mounting plates 20 swing outwards through the two groups of second shifting grooves 405 and the two groups of second shifting shafts 404 to drive the sliding seat 403 to drive the driving rod 401 to move, and the driving rod 401 moves through the second support rod 402 to drive the back plate 40 to open and rotate relative to the bed plate 10, and the two groups of mounting plates 20 swing together through the two groups of second shifting grooves 405 and the two groups of second shifting shafts 404 to drive the sliding seat 403 to drive the driving rod 401 to move in the opposite direction, and the driving rod 401 moves in the opposite direction through the second support rod 402 to drive the back plate 40 to close and rotate relative to the bed plate 10, and the back plate 40 opens or closes and rotates relative to the bed plate 10 to support the back to do standing up exercises. Through the synchronous exercise of leg opening and closing exercises, knee bending exercises and standing up exercises, the rehabilitation exercise effect can be effectively improved.
