Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0019] See the multifunctional fitness wheelchair shown in the picture, at figure 1 , figure 2 Among them, the four bearing seats (3) are fixed in the bottom frame (1) of the wheelchair by bolts (2), and a bearing (4) is installed in each bearing seat (4), a left-handed screw rod (9) and a right-handed screw rod (14) are respectively installed in the bearing (4), and can rotate freely. The two screw rods are arranged symmetrically and have equal pitches. A flat key (11) is installed at the end of the screw rods, and the motor (12) is installed on the chassis (1). In the middle position, the motor (12) drives the left-handed screw rod (9) and the right-handed screw rod (14) to rotate through the key (11), and then drives the left-handed screw ...

Abstract

The invention discloses a multi-functional body-building wheelchair which can be changed into a rocking chair, erect a seat, shift and laterally turn the seat, freely adjust a backrest, and perform simple sitting and lying fitness exercises and vibrational massage. A motor drives screw rods with opposite rotating directions to rotate, and two rocking bars are unfolded through matched nuts and brace rods to become the rocking chair; moreover, the same motor can drive different screw rods to rotate, an electromagnetic clutch is adopted to switch power so as to realize the erection of a seat frame, and a person is transferred to a bed through another screw rod; a controllable air spring controls a six-bar mechanism to freely adjust the angle of the backrest and realize the linkage of the backrest and a pedal frame, and by matching the erection function and the shifting and lateral turning function, the person sitting on the wheelchair can perform the simple sitting and lying fitness exercises; and the motor drives a shaft of which two ends are provided with mass blocks to rotate at a high speed, and the vibrational massage is realized through the dynamic unbalance generated by rotation.

Description

technical field [0001] The invention relates to a body-building aid for the disabled, in particular to a multifunctional body-building wheelchair widely applicable to middle-aged and elderly people, persons with disabilities in legs and feet, and injured and sick persons. Background technique [0002] Existing ordinary wheelchairs, electric wheelchairs and wheelchairs with special functions all have various defects to varying degrees: ordinary wheelchairs have a single function and cannot meet the needs of users; electric wheelchairs can generally only be used as a single means of transportation; and special Functional wheelchairs are complex in structure and poor in effect. In order to overcome the above shortcomings of wheelchairs, the present invention provides a multifunctional modular fitness wheelchair with walking instead of walking, rocking chair, upright, translation and rollover, vibration massage, sitting and lying fitness, and arbitrary adjustment of the backrest...
