Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a wheelchair with shock absorption function for orthopedic care. Background Technology

[0002] Wheelchairs are assistive devices designed specifically for people recovering from spinal, pelvic, or lower limb fractures or post-operative care. They primarily assist people with mobility impairments in moving, rehabilitation, and participating in social life. The core functions of wheelchairs can be categorized into five main areas: basic mobility, rehabilitation medicine, self-care, social participation, and psychological support. Wheelchairs provide indoor and outdoor mobility for people with lower limb disabilities, post-fracture surgery, muscle weakness, or the elderly and frail who are unable to walk independently, addressing their basic daily travel needs. They also enhance patients' self-care abilities, enabling them to complete daily routines and independent home activities.

[0003] When patients use wheelchairs to go out, they will inevitably encounter sloping surfaces. When crossing such surfaces, because the center of gravity of the patient and the wheelchair is high, the center of gravity of the wheelchair is easily shifted to the outside of the four wheels, causing the wheelchair to tip over and the patient to fall and get injured. Especially when the wheelchair is going uphill, the patient may fall and injure the back of the head, seriously endangering the patient's life. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides a wheelchair with shock absorption function for orthopedic care.

[0005] The technical solution is as follows: A shock-absorbing wheelchair for orthopedic care includes a wheelchair body, shock absorbers at the wheels of the wheelchair body, a fixed plate fixed to the wheelchair body, a rotating plate hinged to the fixed plate, a rotating shell fixed to the rotating plate, the rotating shell being limited by the fixed plate after rotation, a support rod slidably connected to the rotating shell, a limit rod fixed to the wheelchair body for limiting the support rod, a hole for the limit rod to pass through in the rotating shell, a first spring between the support rod and the rotating shell, a support plate hinged to the support rod, the support plate having stripes for increasing friction, a spring telescopic rod hinged to the wheelchair body, and the telescopic end of the spring telescopic rod hinged to the rotating shell.

[0006] Furthermore, the wheelchair body is fixedly connected to a fixed shell, the fixed shell is slidably connected to a first sliding rod, the rotating plate is provided with a first limiting groove, and the first sliding rod is inserted into the first limiting groove to limit the rotation plate.

[0007] Furthermore, the wheelchair body is fixedly connected to a spherical shell, the spherical shell is ball-connected to a swinging member, the spherical shell is provided with a mounting groove, a first sliding member is slidably connected in the mounting groove, a second spring is provided between the first sliding member and the spherical shell, the mounting groove is connected to the fixed shell through a pipe, and the swinging member is provided with an annular groove for the first sliding member to be inserted.

[0008] Furthermore, the first sliding member is provided with ball bearings, which are pressed against the oscillating member.

[0009] Furthermore, the rotating shell is fixedly connected to a first pull rope, the wheelchair body is fixedly connected to a first guide member, the first pull rope passes through the first guide member and is fixedly connected to the wheelchair body, the swing member is fixedly connected to a second pull rope, the wheelchair body is fixedly connected to a second guide member, and the second pull rope passes through the second guide member and is fixedly connected to the wheelchair body.

[0010] Furthermore, the rotating shell is slidably connected to a limiting member, a third spring is provided between the limiting member and the rotating shell, and the support rod is provided with equally spaced second limiting grooves. The limiting member is inserted into an adjacent second limiting groove to limit the support rod.

[0011] Furthermore, the support rod is provided with a first sliding groove, and a pressing rod is slidably connected in the first sliding groove. The pressing rod is provided with equally spaced pressing grooves, and the pressing grooves correspond one-to-one with the second limiting grooves. The pressing grooves are used to press the limiting member. The support rod is slidably connected with a second sliding member, and a fourth spring is provided between the second sliding member and the support rod. The second sliding member is provided with a second sliding groove, and a second sliding rod is slidably connected in the second sliding groove. A fifth spring is provided between the second sliding rod and the second sliding member. The second sliding groove and the first sliding groove are connected by a pipe.

[0012] Furthermore, a hydraulic rod is fixedly connected to the rotating shell, and a pressing plate is fixedly connected to the telescopic end of the hydraulic rod. The pressing plate is used to press the second sliding member and the second sliding rod. A pressing member is fixedly connected to the rotating shell, and the pressing member is used to press the second sliding member.

[0013] Furthermore, the wheelchair body is fixedly connected to a fixed seat, the fixed seat is slidably connected to a friction element, a sixth spring is provided between the friction element and the fixed seat, and the friction element is used to pass through the spherical shell to compress the swinging element.

[0014] Furthermore, the wheelchair body is slidably connected to a sliding seat, a seventh spring is provided between the sliding seat and the wheelchair body, and a transmission rod is fixedly connected to the sliding seat, the transmission rod being used to compress the friction element.

[0015] The effects of the above solution are as follows: When the wheelchair body tilts excessively, the rotating shell pops out and extends the support rod, thereby supporting the wheelchair body and preventing it from tipping over due to excessive tilting, thus protecting the patient. Furthermore, the shock absorber reduces shock and improves the patient's comfort.

[0016] The tilting state of the wheelchair body is monitored by the swing component. When the center of gravity of the wheelchair body shifts to the outside of the four wheels, the annular groove is aligned with the first sliding component, thereby causing the rotating shell to pop out automatically, which in turn triggers the support of the wheelchair body and causes the limiting component to limit the support rod, preventing the wheelchair body from tilting at a larger angle.

[0017] By moving the extension end of the hydraulic rod, the limiting device automatically releases the limit on the support rod and automatically retracts the support rod into the rotating shell. Then, by pulling the first and second pull ropes, the patient can retract the rotating shell and support rod by himself without the help of others.

[0018] By using friction components to press against the swing components, the probability of the swing components being accidentally touched and causing a large tilt is reduced. When the patient sits on the wheelchair body, the sliding seat is pressed, which automatically separates the friction components from the swing components, allowing the swing components to work normally.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] Existing wheelchairs are prone to tipping over when encountering slopes due to a shift in the center of gravity, which can lead to injury and compromise patient safety.

[0024] A shock-absorbing wheelchair for orthopedic care, such as Figures 1-6 As shown, the wheelchair includes a wheelchair body 1. Shock absorbers are installed at the wheels of the wheelchair body 1 to improve patient comfort. A fixing plate 101 is fixedly connected to the rear side of the wheelchair body 1. Two rotating plates 102 are hinged to the fixing plate 101. A rotating shell 2 is fixedly connected to the lower side of the two rotating plates 102. The rotating shell 2 is limited by the fixing plate 101 after rotating to its maximum angle. A support rod 3 is slidably connected to the rotating shell 2. The support rod 3 consists of a disc and a rod, with the disc located on the upper side of the rod. A limiting rod 103 is fixedly connected to the wheelchair body 1. The limiting rod 103 has a vertical part and an arc part. The arc part of the limiting rod 103 is used for... The disc of the support rod 3 is limited. The center of the arc of the limiting rod 103 is located on the extension line of the rotating shaft of the rotating plate 102. The rotating shell 2 has a hole for the limiting rod 103 to pass through. A first spring 4 is provided between the support rod 3 and the rotating shell 2. The first spring 4 is initially in a compressed state. The support rod 3 is hinged to a support plate 5. The support plate 5 is provided with stripes to increase friction. When the support plate 5 contacts the ground, it increases its stability. The wheelchair body 1 is hinged to a spring telescopic rod 6. The telescopic end of the spring telescopic rod 6 is hinged to the rotating shell 2. The spring in the spring telescopic rod 6 is also initially in a compressed state, so that the rotating shell 2 can be quickly unfolded.

[0025] like Figure 3 , Figure 4 and Figure 6 As shown, the wheelchair body 1 is fixedly connected to a fixed shell 7, and the fixed shell 7 is slidably connected to a first sliding rod 8. The rotating plate 102 on the right side is provided with a first limiting groove 1021. The first sliding rod 8 is inserted into the first limiting groove 1021 to limit the rotating plate 102. When the first sliding rod 8 is separated from the first limiting groove 1021, the rotating shell 2 is quickly unfolded under the action of the spring telescopic rod 6.

[0026] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, a spherical shell 9 is fixedly connected to the wheelchair body 1, and a swing member 10 is spherically connected to the spherical shell 9. A weight is located on the lower side of the swing member 10 to maintain its vertical position, thereby monitoring the current tilt angle of the wheelchair body 1. The spherical shell 9 is provided with a mounting groove 901, and a first sliding member 11 is slidably connected within the mounting groove 901. Both the fixed shell 7 and the mounting groove 901 are filled with a fluid for transmission, such as hydraulic oil. Seals are provided between the spherical shell 9 and the first sliding member 11, and between the fixed shell 7 and the first sliding rod 8. These are not shown in the figure. The first sliding member 1... A second spring 1101 is provided between the wheelchair body 1 and the spherical shell 9. The second spring 1101 is initially in a compressed state. The mounting groove 901 is connected to the fixed shell 7 through a pipe. The swinging member 10 is provided with an annular groove 1001. When the tilt angle of the wheelchair body 1 is too large, the annular groove 1001 will align with the first sliding member 11, causing the first sliding member 11 to slide out and drive the first sliding rod 8 to move, thereby opening the rotating shell 2. The annular groove 1001 is provided with a slope to press the first sliding member 11, causing the first sliding member 11 to move into the mounting groove 901. The first sliding member 11 is provided with a ball bearing 1102. The ball bearing 1102 presses against the swinging member 10, and the ball bearing 1102 is used to reduce the friction between the first sliding member 11 and the swinging member 10.

[0027] like Figures 1-3 and Figure 7 As shown, the rotating shell 2 is fixedly connected to the first pull rope 12, the wheelchair body 1 is fixedly connected to the first guide member 13, the first pull rope 12 passes through the first guide member 13 and is fixedly connected to the wheelchair body 1, the swing member 10 is fixedly connected to the second pull rope 14, the wheelchair body 1 is fixedly connected to the second guide member 15, the second pull rope 14 passes through the second guide member 15 and is fixedly connected to the wheelchair body 1. The fixed positions of the first pull rope 12 and the second pull rope 14 are both located next to the armrest of the wheelchair body 1, so as to facilitate the operation by the patient.

[0028] like Figure 6 and Figure 9As shown, the rotating shell 2 is slidably connected to a limiting member 16, which is a wedge-shaped block. A third spring 17 is provided between the limiting member 16 and the rotating shell 2. The support rod 3 is provided with equally spaced second limiting grooves 301. The limiting member 16 is inserted into the adjacent second limiting groove 301 to limit the support rod 3. The limiting member 16 is used to limit the support rod 3 in one direction. When the limiting member 16 is inserted into the second limiting groove 301, the support rod 3 cannot be retracted into the rotating shell 2.

[0029] like Figure 4 , Figure 6 and Figure 9 As shown, the support rod 3 is provided with a first sliding groove 302, and a pressing rod 18 is slidably connected in the first sliding groove 302. A sealing element is provided between the lower side of the pressing rod 18 and the support rod 3 (not shown in the figure). The second limiting groove 301 is provided with a limiting part 3011 and a pressing part 3012. When the limiting member 16 contacts the limiting part 3011, the support rod 3 cannot be retracted into the rotating shell 2. When the limiting member 16 contacts the pressing part 3012, the support rod 3 can be retracted into the rotating shell 2 by squeezing out the limiting member 16. The pressing rod 18 is provided with equally spaced pressing grooves 1801, which correspond one-to-one with the second limiting groove 301. The pressing grooves 1801 are used to squeeze the limiting member 16, causing the limiting member 16 to separate from the limiting part 3011. At this time, the support rod 3 can pass through the pressing part 3012. 12. Continue to press the limiting member 16 so that the limiting member 16 cannot limit the support rod 3. The support rod 3 is slidably connected to the second sliding member 19. The second sliding member 19 is provided with an inclined surface. A fourth spring 20 is provided between the second sliding member 19 and the support rod 3. The fourth spring 20 is initially in a compressed state. The second sliding member 19 is provided with a second sliding groove 1901. A second sliding rod 21 is slidably connected in the second sliding groove 1901. A sealing member is provided between the second sliding rod 21 and the second sliding member 19 (not shown in the figure). The second sliding groove 1901 and the first sliding groove 302 are both filled with a fluid for transmission, such as hydraulic oil. A fifth spring 22 is provided between the second sliding rod 21 and the second sliding member 19. The second sliding groove 1901 and the first sliding groove 302 are connected by a pipe.

[0030] like Figures 2-4As shown, a hydraulic rod 23 is fixedly connected to the rotating shell 2. A pressing plate 24 is fixedly connected to the telescopic end of the hydraulic rod 23. The pressing plate 24 is used to press the second sliding member 19 and the second sliding rod 21. A pressing member 25 is fixedly connected to the rotating shell 2. The pressing member 25 is used to press the inclined surface of the second sliding member 19. The second sliding member 19 is initially pressed by the pressing plate 24. The pressing member 25 is L-shaped, and the left side of the vertical part of the pressing member 25 is flush with the left side of the pressing plate 24. The above-mentioned parts for supporting the wheelchair body 1 can be set in multiple sets as needed, and set on the front and left and right sides of the wheelchair body 1, so as to achieve multi-directional anti-tipping of the wheelchair body 1. By simply installing the first sliding member 11 at the corresponding position of the spherical shell 9, the corresponding rotating shell 2 and support rod 3 can support the wheelchair body 1 according to the swing of the swing member 10 relative to the spherical shell 9.

[0031] When a patient tilts while using this device (taking a backward tilt as an example), the wheelchair body 1 tilts backward, while the swing member 10 remains vertical until the first sliding member 11 aligns with the annular groove 1001. Under the action of the second spring 1101, the first sliding member 11 moves forward until it is inserted into the annular groove 1001. At this time, a negative pressure is formed in the mounting groove 901, and the liquid in the fixed shell 7 is drawn into the mounting groove 901 through the pipe. The liquid in the fixed shell 7 decreases, causing the first sliding rod 8 to move forward and separate from the first limiting groove 1021. After the rotating plate 102 loses the limitation of the first sliding rod 8, the rotating shell 2 rotates under the action of the spring telescopic rod 6. When the rotating shell 2 rotates to its maximum angle, the rotating shell 2 is blocked by the fixed plate 101. At the same time, the support rod 3 separates from the limiting rod 103, and the support rod 3 extends quickly under the action of the first spring 4. The support rod 3 drives the support plate 5 to move until it contacts the ground. After the support plate 5 contacts the ground, it rotates adaptively, making the support plate 5 stick to the ground. During this process, the support rod 3 presses the limiting member 16, causing the limiting member 16 to move backward and compress the third spring 17. When the support rod 3 stops moving, the limiting member 16 is inserted into the adjacent second limiting groove 301 under the action of the third spring 17, so that the support rod 3 will not be retracted into the rotating shell 2, thereby supporting the wheelchair body 1 and preventing the wheelchair body 1 from tipping over. When the support rod 3 extends, the support rod 3 drives the second sliding member 19 to move. The second sliding member 19 gradually separates from the pressing member 25. The second sliding member 19 moves to the right under the action of the fourth spring 20 until the second sliding member 19 separates from the pressing member 25. However, at this time, the left side of the vertical part of the pressing member 25 is still within the range of the inclined surface of the second sliding member 19.

[0032] After supporting the wheelchair body 1, the telescopic end of the hydraulic rod 23 extends, simultaneously driving the compression plate 24 to move. The compression plate 24 moves until it contacts the inclined surface of the second sliding member 19, pressing against the inclined surface and causing the second sliding member 19 to move to the left. As the second sliding member 19 moves, it compresses the fourth spring 20. Then, the compression plate 24 passes over the second sliding member 19 and the second sliding rod 21 until the telescopic end of the hydraulic rod 23 contacts the ground. At this point, the telescopic end of the hydraulic rod 23 continues to extend until all the wheels of the wheelchair body 1 are in contact with the ground. The patient then leans forward to adjust their center of gravity and avoids falling again. Afterward, the telescopic end of the hydraulic rod 23 retracts, and the telescopic end of the hydraulic rod 23 drives the compression plate 24 to contact the second sliding rod 21. The second sliding rod 21 then moves towards the fourth sliding member 19. The second slide groove 1901 moves and compresses the fifth spring 22. The liquid in the second slide groove 1901 is forced into the first slide groove 302 through the pipe. The liquid in the first slide groove 302 increases, pushing the extrusion rod 18 to move. The extrusion groove 1801 extrudes the limiting member 16, causing the limiting member 16 to separate from the limiting part 3011. At this time, the limiting member 16 releases its limitation on the support rod 3. The extrusion plate 24 drives the second sliding member 19 to move through the second sliding rod 21. The second sliding member 19 drives the support rod 3 to move. The extrusion part 3012 extrudes the limiting member 16, causing the limiting member 16 to separate from the second limiting groove 301 until the inclined surface of the second sliding member 19 contacts the extrusion member 25. The second sliding member 19 moves to the left under the extrusion of the extrusion member 25. After the extrusion plate 24 separates from the second sliding rod 21, it contacts the second sliding member 19.

[0033] When the compression plate 24 contacts the second sliding member 19, the first pull rope 12 is pulled, causing the rotating shell 2 to rotate. The rotating shell 2 causes the support rod 3 to gradually return to a state perpendicular to the seat of the wheelchair body 1. Then, the compression plate 24 continues to push the second sliding member 19 to move. The second sliding member 19 is squeezed to the left by the compression member 25 until the second sliding member 19 moves to the point of separation from the compression plate 24. At this time, the upper side of the support rod 3 has passed the arc of the limiting rod 103, and the support rod 3 is lifted by the action of the first spring 4. When the new limit rod 103 is pressed against, the second pull rope 14 is pulled. The second pull rope 14 pulls the swing member 10 back to a state perpendicular to the seat of the wheelchair body 1. The inclined surface of the swing member 10 squeezes the ball 1102, and the ball 1102 squeezes the first sliding member 11, so that the first sliding member 11 returns to its original position and recompresses the second spring 1101. At the same time, the first sliding member 11 drives the first sliding rod 8 to re-insert into the first limit groove 1021 to limit the rotating plate 102. At this point, the first pull rope 12 and the second pull rope 14 can be released.

[0034] Example 2

[0035] Based on Example 1, such as Figure 1 , Figure 3 and Figure 7 As shown, the wheelchair body 1 is fixedly connected to two fixed seats 26. Friction members 27 are slidably connected to the fixed seats 26. The friction members 27 are T-shaped, and a sixth spring 28 is provided between the friction members 27 and the front fixed seat 26. The friction members 27 are used to pass through the spherical shell 9 to compress the swing member 10, thereby making the swing member 10 more stable when not in use and reducing the probability of the swing member 10 being accidentally touched and tilting significantly. The wheelchair body 1 is slidably connected to a sliding seat 29. A soft pad is provided on the upper side of the sliding seat 29 to improve patient comfort. A seventh spring 30 is provided between the sliding seat 29 and the wheelchair body 1. A transmission rod 31 is fixedly connected to the sliding seat 29. The transmission rod 31 consists of a vertical part and an inclined part. The inclined part of the transmission rod 31 is used to compress the friction members 27, causing the friction members 27 to move forward and separate from the swing member 10.

[0036] When the patient sits on the wheelchair body 1, the patient's legs will squeeze the sliding seat 29, the sliding seat 29 moves downward and compresses the seventh spring 30. At the same time, the sliding seat 29 drives the transmission rod 31 to move, the transmission rod 31 squeezes the friction member 27, causing the friction member 27 to move forward. The friction member 27 separates from the swing member 10 and compresses the sixth spring 28. After the patient leaves the wheelchair body 1, the sliding seat 29 loses its compression and moves upward under the action of the seventh spring 30. At the same time, the friction member 27 moves backward under the action of the sixth spring 28 to block the swing member 10, reducing the probability of the swing member 10 being accidentally touched and causing a large tilt.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
