Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-slip electric wheelchair. Background Art

[0002] The anti-slip electric wheelchair (medical use) is a kind of electric wheelchair designed specifically for hospital or home care environment, which provides greater stability and safety on slopes or other uneven surfaces.

[0003] Although current technology has many advantages, its disadvantage is that when an electric wheelchair is on a slope, gravity can be decomposed into two components: one is a component parallel to the slope, and the other is a component perpendicular to the slope. The component along the slope generates a force that attempts to make the electric wheelchair slide down the slope. The component perpendicular to the slope can increase the contact pressure between the tire and the ground, thereby increasing the friction. The friction can resist the component along the slope of the electric wheelchair and prevent the electric wheelchair from sliding down the slope. However, the slippery ground will reduce the friction coefficient, thereby reducing the friction, and then make the friction less than the force of the electric wheelchair sliding down, causing the electric wheelchair to slide down the slope. Sliding down the slope may cause the electric wheelchair to suddenly accelerate and slide down, and the user may The user cannot control the wheelchair, resulting in falls and injuries, endangering the user's health. In the process of sliding down a slope, the electric wheelchair may be impacted or collided, causing damage to mechanical parts and reducing the service life of the electric wheelchair. At the same time, when the electric wheelchair is driving on an uneven slope, if there are potholes or bumps on the ground, the wheels may temporarily leave the ground, causing the wheels to not fit tightly against the ground, and then the contact area and pressure between the tire and the ground are reduced, which will cause the friction to decrease. The decrease in friction will directly affect the traction of the electric wheelchair, especially on a slope, which may make it difficult for the electric wheelchair to move forward or stop stably, further increasing the risk of the electric wheelchair sliding down a slope, further endangering the user's health and the service life of the electric wheelchair.

[0035] like Figure 1-5 As shown, two sliders 8 are movably embedded in the inner surfaces of two slide grooves 5, and the slide grooves 5 can limit the movement trajectory of the sliders 8, thereby preventing the sliders 8 from derailing and affecting the use of the equipment.

[0036] like Figure 1-5 As shown, a plurality of rotating shafts 10 are movably embedded in the inner surfaces of the two fixed plates 2 , and the fixed plates 2 can provide support force for the rotating shafts 10 and provide a good working environment for the rotating shafts 10 .

[0037] like Figure 6-8 As shown, two rotating shafts 28 are movably embedded in the inner surfaces of the two positioning plates 25, and two air bags 31 are arranged on the inner surfaces of the two wheel hubs 29. The rotating shafts 28 can transmit the power of the motor 27 to the wheel hubs 29 to make the wheel hubs 29 rotate.

[0038] like Figure 8 As shown, a plurality of telescopic rods 34 are movably embedded in the inner surfaces of a plurality of fixed blocks 32 , and the telescopic rods 34 can transmit the power of the piston 33 to the friction plate 35 , so that the friction plate 35 fits tightly against the slope surface.

[0039] like Figure 1-4 As shown, a plurality of slide bars 12 are movably embedded in the inner surfaces of a plurality of limiting holes 4, and the limiting holes 4 can limit the moving track of the slide bars 12, thereby preventing the slide bars 12 from derailing and affecting the use of the equipment.

[0040] like Figure 5 As shown, multiple springs 22 are fixedly connected to the inner surfaces of multiple slots 20, and multiple springs 22 are fixedly connected to the outer surfaces of multiple friction blocks 23. The springs 22 can provide power for the downward movement of the friction blocks 23 when the pressing blocks 18 move to a lower slope position, so that the friction blocks 23 fit tightly against the ground.

[0041] Working principle: This device is for medical use in anti-slip electric wheelchairs. When the electric wheelchair stops on the slope, the hydraulic cylinder 3 on the fixed plate 2 is started. The hydraulic cylinder 3 moves the tooth plate 7 downward through the telescopic rod 6, and then the tooth plate 7 drives the slider 8 to move on the inner surface of the slide groove 5. When the tooth plate 7 moves downward, it will drive the gear 9 to rotate and the connecting rod 2 17 to move downward, so that the gear 9 drives the connecting plate 11 to move through the rotating shaft 10, and the connecting plate 11 drives the slide bar 12 to move on the inner surface of the limiting hole 4. The slide bar 12 drives the clamping block 15 to move through the connecting rod 14. The limiting plate 13 can prevent the slide bar 12 from being dislocated when moving, affecting the use of the equipment. Because the center of the limiting hole 4 is higher than the center of the wheel hub 29, and because of the special shape of the limiting hole 4, the clamping block 15 makes a circular motion, and then the clamping block 15 clamps the friction plate 35. The rubber pad 16 can increase the friction between the clamping block 15 and the friction plate 35 to prevent friction The plate 35 continues to rotate, and because the friction plate 35 cannot rotate, the possibility of the electric wheelchair sliding on the slope is reduced to a certain extent. At the same time, when the connecting rod 17 moves downward, the pressing block 18 will be driven to move downward, so that the protrusion 24 on the friction block 23 fits with the ground. At this time, the pressing block 18 continues to move downward, thereby making the telescopic rod 21 move on the inner surface of the groove 19, and the spring 22 is compressed. However, because the slope is not necessarily absolutely flat, there will inevitably be uneven places. When the pressing block 18 passes through a lower place, the spring 22 inside the groove 1 will release the elastic potential energy, so that the protrusion 24 on the friction block 23 fits tightly with the ground. Because there are enough friction blocks 23, the spring 22 can be used to make the protrusion 24 on the friction block 23 always fit tightly with the ground, further enhancing the friction between the electric wheelchair and the ground, ensuring the health of the user, and improving the service life of the electric wheelchair.

[0042] When the electric wheelchair moves on the slope, the motor 27 on the support block 26 is started, and the wheelchair frame 1 provides support for the fixed plate 2 and the positioning plate 25. The motor 27 drives the second shaft 28 to rotate through the output shaft, and the second shaft 28 drives the protective shell 30 to rotate through the hub 29. The protective shell 30 uses the cooperation of the fixed block 32 and the telescopic rod 34 to move the friction plate 35 on the ground. Because the slope is not absolutely flat, it is inevitable that there are uneven places. When the friction plate 35 contacts the higher ground, the friction plate 35 will move the piston 33 on the inner surface of the fixed block 32 through the telescopic rod 34, and the air in the airbag 31 has a certain air pressure, which will affect the activity The movement of the plug 33 forms a certain degree of obstruction, thereby making the friction plate 35 fit closely with the higher ground. When the friction plate 35 moves to the lower ground, the air in the airbag 31 will squeeze the piston 33, causing the piston 33 to move on the inner surface of the fixed block 32, thereby making the telescopic rod 34 drive the friction plate 35 to fit closely with the lower ground, thereby making the friction plate 35 fit closely with the uneven ground. There are enough friction plates 35, so that the friction plate 35 can adapt to the ups and downs of the ground by itself, avoiding the problem of the friction plate 35 not contacting the ground, resulting in reduced friction, and further improving the user's health and the service life of the electric wheelchair.
