[0071] Mode one: the old user sits on the adjustable chair 2, and exercises the lower limb strength through the lower limb auxiliary motion assembly 3 and exercises the upper limb strength through the upper limb auxiliary motion assembly 4; and in the process of exercising the upper limb strength, the anti-falling protection structure 403 can handle the situation that the exercise props in hands fall, so that the safety during exercise is ensured.

[0072] Mode two: the adjustable chair 2 is retracted, the old user stands, the lower limb auxiliary motion assembly 3 is not used, and the upper limb strength is exercised through the upper limb auxiliary motion assembly 4.

[0073] Embodiment 2

[0074] Based on the above-mentioned embodiment 1, further description is made.

[0075] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Specifically, the protection frame 201 is a transparent tempered glass frame structure fixed on the top end of the base 1 through bolts.

[0076] The transparent glass frame structure can facilitate observation of the internal structure of the protection frame 201, and thus facilitates timely maintenance of the structure in the protection frame 201.

[0077] The seat back 202 is composed of a backrest and a flat cushion, the flat cushion is fixed on the inner top of the protection frame 201 by bolts, and the backrest extends to the outside of the protection frame 201 and is arranged obliquely;

[0078] When the transparent protection frame 201 structure is removed, the seat back 202 can be removed conveniently, the obliquely arranged backrest can be combined with the movable chair cushion 203 to form a reclining chair structure, which is convenient for the old users to rest when exercising or to sit and train the legs.

[0079] The bottom end of the movable chair cushion 203 is fixedly provided with a multi-section support 2031 and two guide rails 2032, and the two guide rails 2032 are respectively located on the two sides of the multi-section support 2031.

[0080] The two side surfaces of the flat cushion are fixedly provided with guide hooks 2021 by bolts, the guide rails 2032 slide along the guide hooks 2021, and the two ends of the guide rails 2032 are fixedly provided with anti-disengagement heads 2033.

[0081] The movable chair cushion 203, the multi-section support 2031 and the guide rails 2032 move synchronously, the movement direction of the movable chair cushion 203, the multi-section support 2031 and the guide rails 2032 can be controlled due to the limitation of the guide hooks 2021 on the sliding direction of the guide rails 2032, and the movable chair cushion 203 and the seat back 202 always maintain contact during use due to the arrangement of the anti-disengagement heads 2033. During maintenance, the bolts on the guide hooks 2021 can be controlled to be taken out, so that the movable chair cushion 203 and the seat back 202 can be separated and maintained during maintenance.

[0082] Specifically, the chair cushion translation control structure 204 includes a steel structure support 2041 fixed at the top end of the base 1.

[0083] The top end of the steel structure support 2041 is fixedly provided with twenty-four rollers 2042, which are arranged in a horizontal and vertical 6x4 arrangement, and the wheel surface of the roller 2042 is tightly attached to the bottom end surface of the multi-section support 2031.

[0084] The roller 2042 can provide support for the multi-section support 2031 and the movable chair cushion 203, and does not affect the movement of the multi-section support 2031 and the movable chair cushion 203.

[0085] The top end of the steel structure support 2041 is fixedly provided with a linear module 2043, and the guide movement part of the linear module 2043 is fixed to the bottom end of the flat cushion of the seat back 202.

[0086] The linear module 2043 is used to control the movement of the movable chair cushion 203 and the multi-section support 2031, and the roller 2042 is used to ensure the stability of the movement of the movable chair cushion 203 and the movable chair cushion 203.

[0087] Referring to Figure 1 , Figure 5 , in particular, the base 1 is provided with a vertical sliding groove 101, and the lower half of the blocking plate 205 slides in the vertical sliding groove 101.

[0088] When the movable chair cushion 203 extends out of the protection frame 201, the height of the blocking plate 205 is lowered, and the lower half of the blocking plate 205 can be hidden in the vertical sliding groove 101.

[0089] When the movable chair cushion 203 is retracted into the protection frame 201, the height of the blocking plate 205 is raised, and part of the lower half of the blocking plate 205 is still in the vertical sliding groove 101.

[0090] In this way, no matter how high the blocking plate 205 is, the blocking plate 205 will not completely come out of the vertical sliding groove 101, and dust can be prevented from entering the vertical sliding groove 101.

[0091] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , in particular, the lifting control structure 206 includes a first hydraulic pump 2061, and the first hydraulic pump 2061 is fixed to the top end of the base 1.

[0092] The first hydraulic pump 2061 has two output shafts, and each output shaft is fixedly provided with a T-shaped sliding block 2062 at the top end, and the T-shaped sliding block 2062 is fixed to the side surface of the blocking plate 205.

[0093] The first hydraulic pump 2061 cooperates with the output shafts to control the T-shaped sliding block 2062 to slide up and down, thereby controlling the height of the blocking plate 205.

[0094] The side surface of the steel structure support 2041 is provided with two L-shaped limiting supports 2044, and the T-shaped sliding block 2062 slides along the side surface of the L-shaped limiting support 2044.

[0095] The L-shaped limiting support 2044 limits the up-and-down movement direction of the T-shaped sliding block 2062, thereby improving the stability of the T-shaped sliding block 2062 and the blocking plate 205 during up-and-down movement.

[0096] Referring to Figure 1 , Figure 6 , Figure 7Specifically, the adjusting structure 301 comprises a lifter 3011 fixed at the top end of the base 1, and a wide platform 3012 is fixed at the top end of the lifter 3011, and a transverse sliding groove 3013 is formed in the wide platform 3012, a first electric telescopic rod 3014 is fixedly installed at one side of the inside of the transverse sliding groove 3013, and a second electric telescopic rod 3015 is fixedly installed at the other side of the inside of the transverse sliding groove 3013;

[0097] The foot-pedal type trainer 302 comprises a sliding plate 3021, a long pedal 3022 and a cylindrical sliding block 3023, the sliding plate 3021 and the cylindrical sliding block 3023 are both slid along the transverse sliding groove 3013, and a spring rod 3024 is fixedly installed between the sliding plate 3021 and the cylindrical sliding block 3023;

[0098] The output end of the first electric telescopic rod 3014 is fixed to one end of the cylindrical sliding block 3023, and the output end of the second electric telescopic rod 3015 is in contact with the side surface of the sliding plate 3021 but is not fixed.

[0099] By controlling the length of the first electric telescopic rod 3014 and the length of the second electric telescopic rod 3015, the position of the foot-pedal type trainer 302 on the wide platform 3012 can be controlled at this time, and the moving direction of the foot-pedal type trainer 302 is limited by the transverse sliding groove 3013, then the height of the foot-pedal type trainer 302 and the wide platform 3012 can be controlled by controlling the height of the lifter 3011.

[0100] When the lower limbs are exercised, the feet are pedaled on the long pedal 3022, then the long pedal 3022 is pushed, the long pedal 3022 is stressed, the long pedal 3022 and the sliding plate 3021 are synchronously slid along the transverse sliding groove 3013, the spring rod 3024 is further compressed, the elastic force is increased, and the reaction force on the feet can be generated, in this way, with the cycle of stretching and contracting of the feet, the process of cyclic compression and release of the spring rod 3024, and the synchronous movement of the long pedal 3022 and the sliding plate 3021 back and forth, the effect of muscle strength exercise of the feet can be achieved.

[0101] Specifically, the long pedal 3022 is rotated around the sliding plate 3021 through a hinge, and a limiting rod 3025 is fixed at the bottom end of the long pedal 3022.

[0102] When the long pedal 3022 is unidirectionally rotated by a certain angle, if the end of the long pedal 3022 contacts the slide plate 3021 or the limiting rod 3025 contacts the slide plate 3021, the long pedal 3022 cannot be rotated any more, so that the rotation angle of the long pedal 3022 is limited, and the angle range between the long pedal 3022 and the slide plate 3021 is 10-60°, so that the bending angle of the ankle of the old user during lower limb exercise can be changed, the comfort of lower limb training is improved, meanwhile, the long pedal 3022 is not excessively rotated, and the ankle sprain during lower limb exercise is avoided.

[0103] Referring to Figure 1 , Figure 8 , Figure 9 Specifically, the two ends of the high frame 401 are smooth steel rod structures 4011, and the bottom end of the high frame 401 is welded and fixed with the top end of the base 1. The two upper limb auxiliary exercise assemblies 4 are symmetrically distributed on the two sides of the adjustable reclining chair 2.

[0104] The two upper limb auxiliary exercise assemblies 4 can conveniently simultaneously exercise the two upper limbs of the old user.

[0105] Specifically, the counterweight structure 402 is an integrated structure composed of a handle 4021, two slide columns 4022 and a counterweight box 4023, and the slide column 4022 slides along the corresponding smooth steel rod structure 4011.

[0106] The handle 4021 is held on the hand, the entire counterweight structure 402 can be lifted, and the weight of the counterweight structure 402 is utilized to complete the strength exercise of the upper limb during the lifting process.

[0107] The counterweight box 4023 is filled with counterweight blocks 4024.

[0108] According to the requirement of strength exercise, the counterweight blocks 4024 of corresponding weight can be filled to ensure the effect of strength training.

[0109] The top end of the output shaft rod of the No. 2 hydraulic pump 4025 is fixedly provided with a narrow platform 4026, and the narrow platform 4026 contacts but is not fixed with the bottom end of the corresponding counterweight box 4023.

[0110] The height of the narrow platform 4026 can be controlled by the No. 2 hydraulic pump 4025 cooperating with the output shaft rod, so as to control the initial height of the counterweight box 4023. At this time, the initial height of the counterweight box 4023 during upper limb training can be conveniently controlled according to the sitting or standing posture of the old user.

[0111] Specifically, the anti-falling protection structure 403 includes a transverse electric telescopic rod 4031, the fixed end of the transverse electric telescopic rod 4031 is fixed on the side of the counterweight box 4023, the output end of the transverse electric telescopic rod 4031 is fixed with a steel plate 4032, the side of the steel plate 4032 is fixedly installed with three insertion rods 4033;

[0112] The side of one of the slide columns 4022 is provided with a through hole, the insertion rod 4033 passes through the through hole and is in contact with and pressed against the side of the smooth steel rod structure 4011;

[0113] The speed sensor is hidden and fixed in the inside of the counterweight box 4023.

[0114] When the Hall speed sensor of the model AH3503 detects that the speed of the counterweight box 4023 is abnormal, that is, the steel plate 4032 is controlled by the transverse electric telescopic rod 4031, the insertion rod 4033 is pushed forward, the insertion rod 4033 passes through the through hole and further presses against the side of the smooth steel rod structure 4011, and then the friction force is used to force the counterweight box 4023 to slow down and fall.

[0115] In this way, when the upper limbs of the old user are moved and lose strength, and the counterweight box 4023 falls from the hand, the counterweight box 4023 is prevented from falling quickly and colliding and being damaged, at the same time, the situation that the counterweight block 4024 appears when the counterweight box 4023 is quickly raised and lowered is avoided, the safety of the entire counterweight structure 402 when being pulled up is improved, and then the safety of the upper limb movement is ensured.

[0116] Embodiment 3:

[0117] Based on the above-mentioned embodiments 1 and 2, further description is made.

[0118] In order to facilitate the control of the entire device, a remote controller and voice control can be configured for the entire device.

[0119] Working principle:

[0120] The old user can perform upper limb strength and lower limb strength exercise through the exercise device.

[0121] The exercise device has two exercise modes:

[0122] Mode one: the elderly user walks to the elevator 3011 and sits on the adjustable recliner 2, at this time, the height of the foot pedal trainer 302 is controlled by the elevator 3011, and then the length of the first electric telescopic rod 3014 and the second electric telescopic rod 3015 is controlled, the position of the entire foot pedal trainer 302 is controlled, and the feet of the elderly user are stepped on the long pedal 3022. At this time, the feet push the long pedal 3022, the long pedal 3022 is stressed, the long pedal 3022 and the sliding plate 3021 are synchronously slid along the transverse sliding groove 3013, the spring rod 3024 is further compressed, the elastic force is increased, and the reaction force can be generated on the feet. In this way, with the cycle of stretching and contracting of the feet, the spring rod 3024 is cyclically compressed and released, and the long pedal 3022 and the sliding plate 3021 move back and forth synchronously, which can achieve the effect of muscle strength exercise of the feet.

[0123] And in the first exercise mode, the upper limbs can be exercised, specifically: the second hydraulic pump 4025 cooperates with the output shaft rod to control the height of the narrow platform 4026, thereby controlling the initial height of the counterweight box 4023, so that the hands of the elderly user can hold the handle 4021 when the hands are hanging down. Then, according to the requirements of strength exercise, the corresponding weight of the counterweight block 4024 can be filled to ensure the effect of strength training. With the force of the upper limbs, the entire counterweight structure 402 slides up and down along the smooth steel rod structure 4011 to complete the exercise of the upper limbs.

[0124] And during the exercise process: when the Hall speed sensor AH3503 detects that the speed of the counterweight box 4023 is abnormal, the steel plate 4032 and the plug rod 4033 are pushed forward by the transverse electric telescopic rod 4031, the plug rod 4033 penetrates through the perforation and further presses the side of the smooth steel rod structure 4011, thereby using the friction force to force the counterweight box 4023 to slow down and fall. When the elderly user has muscle weakness during exercise, safety accidents caused by falling of the exercise props can be effectively prevented, and the safety performance of the entire device during use is ensured.

[0125] Mode two: the seat back 202 of the adjustable recliner 2 is retracted, specifically: the linear module 2043 controls the movement of the movable chair cushion 203 and the multi-section support 2031 until the seat back 202 is completely retracted into the protection frame 201, at the same time, the first hydraulic pump 2061 cooperates with the output shaft rod to control the up and down sliding of the T-shaped sliding block 2062, thereby controlling the height of the blocking plate 205 until the top of the blocking plate 205 is attached to the bottom end of the seat back 202, and the seat back 202 and the blocking plate 205 form a backable wall structure. In this way, the elderly user can be attached to the wall structure to assist the elderly user to stand and exercise, and the elderly user stands to exercise the lower limbs, and the way of upper limb exercise is the same as that in mode one.
