Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, and in particular to an elderly-assisting exercise wheelchair that assists the elderly in lower limb exercises. Background Technology

[0002] my country has entered an aging society, and the elderly often experience difficulty walking due to aging or other diseases. Designing a new type of wheelchair with multiple functions that can assist the elderly in exercising has become a problem that technical personnel in this industry need to solve. Utility Model Content

[0003] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. To overcome the aforementioned deficiencies of existing technologies, this utility model provides an elderly-assisting exercise wheelchair that assists with lower limb exercises, aiming to solve the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides an elderly-assisted exercise wheelchair that assists the elderly in lower limb exercises. The wheelchair includes: a side plate inclinedly connected to the front of a main body base plate, with pedals provided on the inner and outer surfaces of the side plates; two sets of side plates and pedals are symmetrically arranged about the longitudinal midline of the main body base plate; and a lower limb exercise mechanism, comprising a connecting plate, a slider, a groove, and a spring; the connecting plate is located on the side of the pedal near the side plate, and extends into the side plate on the side away from the pedal; the slider is located in the connecting plate, encasing the outside of the slider and slidably connected to it; the spring's first end is located on the lower end face of the slider, and the spring's end is connected to the inner wall of the groove, forming an elastic connection structure.

[0005] The main base plate is for the user to sit on. The side plates are integrally molded with the main base plate, acting as connectors to link the pedals to the main base plate. The pedals act as supports, supporting the user's feet. A connecting plate is fixedly connected to the pedals. When the pedals are subjected to pressure from the user's lower limbs, the connecting plate causes the slider to move longitudinally along the groove. During this movement, the slider exerts downward pressure on the spring, causing the spring to deform. When the pressure on the pedals disappears, the slider returns to its original position under the elasticity of the spring, thus providing a lower limb exercise function. When the lower limb exercise mechanism is not in use, the slider and the groove are fixed together with bolts or other fasteners.

[0006] Preferably, the pedal and the connecting plate are fixedly connected, and the upper surface of the pedal is provided with anti-slip ridges.

[0007] The fixed connection design ensures the stability of the connection between the pedal and the connecting plate. The anti-slip textured design increases the friction between the user's foot and the pedal, preventing slippage and increasing support.

[0008] Preferably, a limiter is slidably installed inside the slide groove, and the end of the limiter away from the pedal extends to the outside through a pre-set clearance hole on the slide groove.

[0009] The sliding connection design allows the limiter to be adjusted up and down within the slide groove, thereby changing the range of spring extension and contraction. This allows the user to adjust the downward pressure applied, enabling them to tailor the intensity of lower limb exercises to their specific needs. One end of the limiter extends outward to facilitate adjustment of its longitudinal position within the slide groove, and the clearance hole is secured to the slide groove using bolts or other fasteners.

[0010] Preferably, the main body base plate is provided with a back plate, and the back plate is located on the rear side of the upper surface of the main body base plate, and the connection between the back plate and the main body base plate is designed with an inclination, forming an angle of 30 degrees.

[0011] The main body base plate and back plate are integrally molded, ensuring the stability of the connection between the back plate and the main body base plate, while also guaranteeing user safety. The 30-degree angle design improves the comfort of the user's lower back during use.

[0012] Preferably, the back plate has a drive structure, which includes a travel wheel, a handrail, and a push wheel; the travel wheel is set on the lower end face of the main body base plate via a connecting shaft, and two travel wheels are distributed about the longitudinal center axis of the main body base plate; the handrail is set parallel to the top of the back plate, and two handrails are distributed about the longitudinal center axis of the back plate; the push wheel is set on the outer surface of the main body base plate via a connecting shaft, and two push wheels are distributed about the longitudinal center axis of the main body base plate, and the push wheel is located in front of the travel wheel.

[0013] The drive structure is the moving part of this device. Both the driving wheel and the push wheel are rotatably connected. In use, the user can move the device by manually cranking the push wheel, which in turn moves it using the driving wheel. The handle design allows family members to easily push the device using the driving wheel, thus providing two modes of movement.

[0014] Preferably, it also includes baffles, which are connected to the upper surface of the main body base plate, and there are two baffles distributed about the longitudinal midline of the main body base plate.

[0015] The baffles are vertically connected to both sides of the main body base plate to prevent users from falling to either side, thus providing protection and demonstrating the safety of the device during use.

[0016] Preferably, the baffle has evenly distributed circular exhaust holes on its surface, and a protective pad is provided on the top of the baffle, and the protective pad is made of rubber.

[0017] The vent design ensures airflow between the two baffles, achieving heat dissipation in high-temperature conditions and preventing airflow by covering them with clothing or other items in low-temperature conditions, thus achieving a heat-insulating effect. The rubber pads ensure comfort when the user's arms contact the baffles, while also providing sweat absorption and slip resistance.

[0018] Preferably, it also includes through holes, which are pre-set on the upper surface of the main body base plate and have a strip-shaped structure, and the strip-shaped through holes are evenly distributed on the upper surface of the main body base plate.

[0019] The perforated design is intended to prevent users from feeling stuffy and hot when sitting for long periods of time, and to allow for ventilation.

[0020] Preferably, it also includes massage protrusions, which are preset on the surface of the back plate near the main body bottom plate, and the massage protrusions are distributed in a group or more at equal intervals in the horizontal direction.

[0021] The massage protrusions are designed so that when the user leans against the backrest, the protrusions can stimulate different acupoints, thus providing a massage effect.

[0022] Preferably, it also includes a storage basket, which is attached to the side of the back panel away from the main body base plate.

[0023] The storage basket is fixedly attached to the back panel and is used to place personal items, thus providing storage functionality.

[0024] The beneficial effects of this utility model are: When in use, this utility model is equipped with a lower limb exercise mechanism. When the pedal is subjected to pressure from the user's lower limbs, the connecting plate causes the slider to move longitudinally along the inside of the groove. During the movement, the slider applies downward pressure to the spring, causing the spring to deform. When the pressure on the pedal is removed, the slider returns to its original position under the elasticity of the spring, thus forming a function of exercising the user's lower limbs.
