Description
Technical Field
[0001] This invention relates to the field of wheelchair technology, specifically to a wheelchair with adjustable seat temperature. Background Technology
[0002] The global population aging process continues to accelerate. By the end of 2022, China's elderly population aged 60 and above reached 280 million, accounting for 17.9% of the total population. At the same time, there are approximately 85 million people with disabilities in China, of which more than 24 million have physical disabilities. The number of people who rely on wheelchairs is large and growing year by year. As a core mobility tool, wheelchairs have shifted from basic mobility needs to comprehensive needs such as comfort, health, and intelligence. The functional shortcomings of traditional wheelchairs are becoming increasingly prominent, and they cannot meet the physiological adaptation needs of users who sit for long periods of time. Traditional wheelchairs typically use ordinary sponge, leather, or breathable mesh for their seats and backrests. These materials have poor thermal conductivity and low ventilation efficiency. When users sit for extended periods, heat cannot dissipate from the contact surface between the body and the seat, leading to increased local temperature, sweat buildup, and a hot and humid environment. This environment significantly increases the risk of pressure sores, eczema, and maceration dermatitis. To address this issue, existing solutions often involve adding a temperature control component to the wheelchair. This component typically uses resistance wire heating to heat the seat and an exhaust fan to circulate air, thereby controlling the seat temperature and reducing the incidence of pressure sores and various skin conditions. However, most existing chairs are made of ordinary foam. If a patient sits in a wheelchair for a long time, the middle of the foam seat will collapse due to the pressure of the human body. Although the foam material can recover on its own in the early stages, it is very easy for the middle of the foam seat to collapse and not recover after long-term use. This will cause the foam to become dense inside, reducing the effectiveness of ventilation and cooling of the seat and affecting the use of the wheelchair.
[0003] In summary, to solve the technical problems raised in this paper, this invention proposes a wheelchair with adjustable seat temperature difference. Summary of the Invention
[0004] To address the issue mentioned above where existing seat foam materials, while initially self-recovering, tend to collapse in the center after prolonged use, leading to a denser internal structure and reduced ventilation and cooling effectiveness, thus impacting wheelchair usability, this invention proposes a wheelchair with adjustable seat temperature. This wheelchair includes a wheelchair body and a seat cushion, with the seat cushion positioned on the wheelchair body. The wheelchair body also includes: The mounting plate is located under the seat cushion, and a temperature control component is installed on the mounting plate; the temperature control component is in contact with the seat cushion. The mounting block is installed on the wheelchair body, and the mounting block also has a backrest; and the seat cushion is installed on the mounting block. The mounting slot is formed on the mounting block. The mounting slot contains a mounting cylinder, and the mounting cylinder is slidably connected to a mounting post. The mounting cylinder contains a return spring, and the lower end of the mounting post is connected to the return spring. The mounting post corresponds to the mounting plate. The fixing groove is formed on the mounting block, and the size of the fixing groove is larger than that of the mounting groove. The fixing groove is located above the mounting groove, and the transition between the fixing groove and the mounting groove is stepped. The mounting ring is located inside the fixing groove, and the upper middle part of the mounting ring is arc-shaped and concave inward. The outer diameter of the mounting ring is the same as the diameter of the fixing groove. The mounting ring is sleeved on the outside of the mounting post, and a slider is provided at the middle ring hole of the mounting ring. A sliding groove is opened on the outside of the mounting post, and the slider is slidably connected in the sliding groove. In the initial state, the mounting ring overlaps the bottom wall of the fixing groove.
[0005] The elastic metal sheet is arc-shaped, and there are multiple elastic metal sheets installed circumferentially on the outside of the mounting post. In the initial state, the elastic metal sheet is located on the upper side of the mounting ring. Preferably, the upper end of the mounting ring is provided with multiple strip grooves; and the strip grooves correspond to the elastic metal sheet, with the elastic metal sheet located above the strip groove in the initial state.
[0006] Preferably, the mounting ring is provided with through slots evenly spaced and located between adjacent strip slots. A drive motor is provided on the bottom wall of the mounting slot, and the output end of the drive motor is connected to the mounting cylinder, so that the drive motor can drive the mounting cylinder to rotate. Fan blades are provided on the outer side of the mounting cylinder, and a miniature fan is provided on the bottom wall of the mounting slot.
[0007] Preferably, an annular plate is rotatably connected to the outer side of the mounting plate, and the upper end of the annular plate has evenly distributed arc-shaped protrusions; the lower end of the annular plate has a groove; the upper end of the mounting column is provided with a protrusion, and when the seat cushion is installed, the protrusion is embedded into the groove.
[0008] Preferably, the upper end of the annular plate has multiple cylindrical rods axially distributed, and the arc-shaped protrusions are evenly distributed on the cylindrical rods.
[0009] Preferably, a flexible graphite plate is provided at the upper end of the mounting plate, the middle part of the flexible graphite plate is connected to the middle part of the mounting plate, there is a gap between the edge of the flexible graphite plate and the mounting plate, and the columnar rod is located between the flexible graphite plate and the mounting plate.
[0010] Preferably, the upper end of the mounting column is provided with a cylindrical groove, and the inner diameter of the cylindrical groove is the same as the outer diameter of the annular plate. The protrusion is set inside the cylindrical groove, and when the seat cushion is installed, the mounting plate and the annular plate enter the cylindrical groove.
[0011] Preferably, a placement groove is provided on the wall of the fixing groove, and a blocking block is slidably connected inside the placement groove. The lower end of the blocking block has an arc-shaped structure, and a ball bearing is provided on the arc surface of the lower end of the blocking block. A push rod is fixed to one end of the blocking block inside the placement groove, and the end of the push rod away from the blocking block is located on the side of the mounting block.
[0012] The beneficial effects of this invention are as follows: The spring in the mounting cylinder elastically returns to its original position, pushing the mounting post upwards. This causes the mounting post to move upwards, pulling the elastic metal plate out of the groove. The upper end of the mounting post extends beyond the middle of the mounting ring. During this process, the mounting post and the elastic metal plate push the bottom of the seat cushion, keeping the edge of the cushion fixed to the mounting block. The middle of the cushion moves upwards, pushing the cushion back to its original position. This prevents the middle of the cushion from collapsing downwards after prolonged compression, thus avoiding a negative impact on the patient's experience. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0015] Example 1: like Figures 1 to 11 As shown; a wheelchair with adjustable seat temperature, the wheelchair includes a wheelchair body 1 and a seat cushion 2, the seat cushion 2 being disposed on the wheelchair body 1; the wheelchair body 1 also includes: Mounting plate 21 is located below seat cushion 2, and a temperature control component is provided on mounting plate 21; the temperature control component is in contact with seat cushion 2. Mounting block 11 is mounted on wheelchair body 1, and a backrest 12 is also mounted on mounting block 11; and seat cushion 2 is mounted on mounting block 11. The mounting groove 13 is formed on the mounting block 11. The mounting groove 13 is provided with a mounting cylinder 14. The mounting cylinder 14 is slidably connected with a mounting post 15. The mounting cylinder 14 is provided with a return spring. The lower end of the mounting post 15 is connected to the return spring, and the mounting post 15 corresponds to the mounting plate 21. A fixing groove 16 is formed on the mounting block 11, and the size of the fixing groove 16 is larger than the size of the mounting groove 13. The fixing groove 16 is located above the mounting groove 13, and the transition between the fixing groove 16 and the mounting groove 13 is stepped. The mounting ring 17 is located inside the fixing groove 16, and the upper middle part of the mounting ring 17 is arc-shaped and concave inward. The outer diameter of the mounting ring 17 is the same as the diameter of the fixing groove 16. The mounting ring 17 is sleeved on the outside of the mounting post 15, and a slider is provided at the annular hole in the middle of the mounting ring 17. A sliding groove is opened on the outside of the mounting post 15, and the slider is slidably connected in the sliding groove. In the initial state, the mounting ring 17 overlaps the bottom wall of the fixing groove 16. The elastic metal sheet 18 is arc-shaped, and there are multiple elastic metal sheets 18. They are axially installed on the outside of the mounting post 15, and in the initial state, the elastic metal sheet 18 is located on the upper side of the mounting ring 17. Multiple strip grooves 171 are evenly provided on the upper end of the mounting ring 17; and the strip grooves 171 correspond to the elastic metal sheet 18. In the initial state, the elastic metal sheet 18 is located above the strip grooves 171. The specific workflow is as follows; When in use, the seat cushion 2 and the wheelchair are installed together. The wheelchair is equipped with a display panel, forward and shift buttons, and the backrest 12 of the wheelchair contains a main control chip, a wireless communication module, a security encryption chip, and sensor components. The sensor components include temperature sensors, pressure sensors, heart rate sensors, and human posture tilt sensors installed in the backrest 12. The sensor components are interconnected with a medical and health big data sharing platform. The medical and health big data sharing platform is an existing medical big data platform, such as Alibaba Cloud Health, Huawei Cloud Medical, or a regional health platform. The pressure sensors, heart rate sensors, and human posture tilt sensors inside the backrest 12 are all connected to the medical and health big data sharing platform through the wireless communication module. This allows the sensor components inside the wheelchair to detect the patient's vital signs in real time when the patient is using the wheelchair and transmit the patient's vital signs to the medical and health big data sharing platform. This facilitates the comparison of vital sign data by medical staff in the background and real-time determination of the user's health status. Furthermore, when the patient uses the wheelchair, their buttocks press against the seat cushion 2, causing the middle of the seat cushion 2 to concave downwards. The mounting plate 21 in the middle of the seat cushion 2 moves downwards, and during this process, the mounting plate 21 presses against the upper end of the mounting post 15. After being pressed, the upper end of the mounting post 15 moves downwards within the mounting cylinder 14. Because a mounting ring 17 is provided in the fixing groove 16, and the outer diameter of the mounting ring 17 is larger than the outer diameter of the mounting groove 13, the lower side of the outer ring of the mounting ring 17 rests on the bottom wall of the fixing groove 16. The middle of the mounting ring 17 is fitted onto the outer side of the mounting post 15, and a slider is provided in the middle of the mounting ring 17. A sliding groove is opened on the outer side of the mounting post 15, allowing the slider to slide smoothly within the groove. When the mounting plate 21 presses against the mounting post 15, the mounting post 15 slides downward in the middle of the mounting ring 17, and the slider in the middle of the mounting ring 17 slides in the groove on the outside of the mounting post 15. Furthermore, by opening a strip groove 171 at the upper end of the mounting ring 17, and when the patient squeezes the seat cushion 2, the upper end of the mounting post 15 moves downward, causing the elastic metal sheet 18 to enter the strip groove 171. Therefore, the lower end of the seat cushion 2 is located in the recess at the upper end of the mounting ring 17. The upper end of the mounting ring 17 is an arc-shaped concave shape, so that when the patient sits on the seat cushion 2, the patient's buttocks are embedded in the arc-shaped concave shape at the upper end of the mounting ring 17, while the outside of the mounting ring 17 supports the patient's legs, thus improving the patient's comfort in the wheelchair. Furthermore, by setting a temperature control component above the mounting plate 21, the temperature control component is based on existing technology, such as an electric heating plate. When the temperature sensor in the sensor component detects that the outside temperature is low, the temperature sensor transmits the ambient temperature data to the medical and health big data platform. Subsequently, the main control chip controls the temperature control component to heat up. After the temperature control component heats up, the temperature is transmitted to the sponge layer in the seat cushion 2, and then transmitted to the buttocks of the human body through the seat cushion 2; thereby increasing the temperature of the buttocks of the human body and improving the patient's comfort. When the patient gets up from the wheelchair, the outer ring of the seat cushion 2 is fixed in the mounting block 11, preventing it from moving. The seat cushion 2 is no longer compressed by the patient, and the mounting post 15 is no longer compressed by the mounting plate 21 at the lower end of the seat cushion 2. The spring in the mounting cylinder 14 is no longer compressed and elastically resets. This reset pushes the mounting post 15, causing it to move upwards within the mounting cylinder 14. This causes the elastic metal sheet 18 to move upwards, creating a groove 171. The upper end of the mounting post 15 extends beyond the middle of the mounting ring 17. During this process, the mounting post 15 and the elastic metal sheet 18 push the seat cushion 2 downwards, keeping the edge of the seat cushion 2 fixed to the mounting block 11, while the middle of the seat cushion 2 moves upwards, pushing it back to its original position. This prevents the middle of the seat cushion 2 from collapsing downwards after prolonged compression, thus avoiding a negative impact on the patient's experience.
[0016] Example 2: like Figures 2 to 11 As shown; the mounting ring 17 is evenly provided with through slots 172, and the through slots 172 are located between adjacent strip slots 171. The bottom wall of the mounting groove 13 is provided with a drive motor 131, and the output end of the drive motor 131 is connected to the mounting cylinder 14, so that the drive motor 131 can drive the mounting cylinder 14 to rotate; the outer side of the mounting cylinder 14 is provided with fan blades 141; and the bottom wall of the mounting groove 13 is provided with a miniature fan 132. The wall of the fixed groove 16 is provided with a placement groove 161. A blocking block 162 is slidably connected inside the placement groove 161. The lower end of the blocking block 162 has an arc-shaped structure, and a ball is provided on the arc surface of the lower end of the blocking block 162. A push rod 163 is fixed to one end of the blocking block 162 inside the placement groove 161. The end of the push rod 163 away from the blocking block 162 is located on the side of the mounting block 11. The specific workflow is as follows; Based on the above embodiments, through slots 172 are evenly formed on the mounting ring 17, and the through slots 172 are located between adjacent strip slots 171. A drive motor 131 is installed on the bottom wall of the mounting groove 13, and the output end of the drive motor 131 is connected to the lower end of the mounting cylinder 14. When the drive motor 131 is working, it can drive the mounting cylinder 14 to rotate. The mounting cylinder 14 drives the internal mounting column 15 to rotate, and the sliding groove at the upper end of the mounting column 15 rotates synchronously. This causes the sliding groove at the upper end of the mounting column 15 to drive the slider in the middle of the mounting ring 17 to rotate, thereby causing the mounting ring 17 to rotate synchronously. During this process, fan blades 141 are provided on the outer wall of the mounting cylinder 14. When the mounting cylinder 14... When rotating, the mounting cylinder 14 drives the fan blades 141 to rotate. The rotation of the fan blades 141 disturbs the surrounding airflow, causing the gas in the mounting groove 13 to rise and enter the seat cushion 2. The gas is then transferred to the buttocks of the human body through the seat cushion 2, thereby ventilating the buttocks. If the sensor component in the backrest 12 detects that the outside temperature is high, it transmits the data to the medical and health big data platform, and then controls the micro fan 132 on the bottom wall of the mounting groove 13 to rotate. Multiple micro fans 132 on the bottom wall of the mounting groove 13 start synchronously, causing the micro fans 132 to disturb the airflow in the mounting groove 13. Based on the rotation of the mounting cylinder 14, the airflow through the seat cushion 2 is accelerated, thereby improving the ventilation effect of the seat cushion 2 and improving the patient's comfort. Based on the above, a placement groove 161 is opened in the wall of the fixing groove 16, and a blocking block 162 is slidably connected in the placement groove 161. The lower end of the blocking block 162 has an arc-shaped structure. At the same time, a push rod 163 is set at the end of the blocking block 162 away from the middle of the cushion 2, and the end of the push rod 163 away from the blocking block 162 is located outside the mounting block 11. When the patient sits on the cushion 2, the push rod 163 is pulled, so that the blocking block 162 returns to the placement groove 161. At this time, when the mounting cylinder 14 rotates, the mounting post 15 on the mounting cylinder 14 rotates synchronously, and the elastic metal on the mounting post 15... When the elastic metal sheet 18 rotates synchronously, the blocking block 162 does not obstruct the elastic metal sheet 18. When the patient gets up from the wheelchair, the patient no longer presses against the seat cushion 2, so the spring between the mounting cylinders 14 is no longer compressed and the spring is reset by its own elastic deformation. The mounting column 15 moves upward in the mounting cylinder 14, the elastic metal sheet 18 extends out from the strip groove 171, and at the same time pushes the push rod 163, so that the blocking block 162 extends out from the placement groove 161. Then the drive motor 131 is started, the mounting cylinder 14 rotates, the mounting cylinder 14 drives the mounting column 15 to rotate, and the mounting column 15 drives the... As the flexible metal plate rotates, it is positioned above the mounting ring 17. During rotation, the end of the flexible metal plate furthest from the mounting post 15 is pressed against the arc-shaped surface of the lower end of the blocking block 162. As the flexible metal sheet 18 is pressed by the arc-shaped surface of the blocking block 162, it bends, causing it to detach from the bottom of the seat cushion 2. As the mounting post 15 continues to rotate, when the flexible metal sheet 18 passes the blocking block 162, it is elastically reset and re-contacts the bottom of the seat cushion 2. Furthermore, due to the rapid elastic recovery of the elastic metal sheet 18, the elastic metal sheet 18 will pat the bottom of the seat cushion 2. As the drive motor 131 continues to rotate, the elastic metal sheet 18 continuously pats the bottom of the seat cushion 2. When the seat cushion 2 is patted, the compression of the seat cushion 2 due to prolonged sitting causes the fine fibers inside the sponge to stick together tightly. The patting vibration breaks up the sticky structure, and the fibers in the sponge return to a relaxed state, increasing the fluffiness. This prevents the fibers inside the seat cushion 2 from sticking together and causing poor breathability, and also increases the fluffiness of the seat cushion 2, improving the comfort of the patient sitting in the wheelchair.
[0017] Example 3: like Figures 1 to 11 As shown; an annular plate 22 is rotatably connected to the outer side of the mounting plate 21, and arc-shaped protrusions 23 are evenly distributed on the upper end of the annular plate 22; a groove 24 is provided at the lower end of the annular plate 22; a protrusion 151 is provided at the upper end of the mounting post 15, and when the seat cushion 2 is installed, the protrusion 151 is embedded in the groove 24. Multiple cylindrical rods 25 are axially distributed on the upper end of the annular plate 22, and arc-shaped protrusions 23 are evenly distributed on the cylindrical rods 25. A flexible graphite plate 26 is provided at the upper end of the mounting plate 21. The middle part of the flexible graphite plate 26 is connected to the middle part of the mounting plate 21. There is a gap between the edge of the flexible graphite plate 26 and the mounting plate 21. The column rod 25 is located between the flexible graphite plate 26 and the mounting plate 21. The specific workflow is as follows; Based on the above embodiments, when the patient sits in the wheelchair for an extended period, the drive motor 131 rotates, causing the mounting cylinder 14, mounting column 15, and elastic metal sheet 18 to rotate. As the mounting column 15 rotates, it causes the protrusion 151 above it to rotate as well. The protrusion 151 is embedded in the groove 24, causing the annular plate 22 to rotate via the groove 24. The cylindrical rod 25 above the annular plate 22 rotates synchronously, and the arc-shaped protrusion 23 on the cylindrical rod 25 rotates below the seat cushion 2. During this process, the patient sits in the seat, causing the annular plate 22, cylindrical rod 25, and arc-shaped protrusion 23 to rotate below the patient's buttocks. This allows the arc-shaped protrusion 23 to massage the patient's buttocks through the sponge layer. As the arc-shaped protrusion 23 rotates, it also squeezes and pushes the patient's buttocks, alleviating stiffness and discomfort caused by prolonged sitting and improving patient comfort. Furthermore, a flexible graphite plate 26 is provided at the upper end of the mounting plate 21, with its middle portion connected to the middle portion of the mounting plate 21. A gap exists between the edge of the flexible graphite plate 26 and the mounting plate 21. A columnar rod 25 is positioned between the flexible graphite plate 26 and the mounting plate 21. When the columnar rod 25 rotates, it does not directly contact the lower part of the seat cushion 2, allowing the columnar rod 25 and the arc-shaped protrusion 23 to rotate below the flexible graphite plate 26. The flexible graphite plate 26 has good thermal conductivity. The flexible graphite plate 26 has a smooth surface and a low coefficient of friction, which improves the smoothness of rotation of the cylindrical rod 25 and the arc-shaped protrusion 23 when they rotate on the underside of the flexible graphite plate 26, preventing them from directly contacting the sponge layer. Furthermore, when the patient sits on the cushion 2, the flexible graphite plate 26 isolates the arc-shaped protrusion 23, thus preventing it from directly pressing against the body and causing significant stinging. This improves patient comfort.
[0018] Example 4: like Figures 2 to 11 As shown; the upper end of the mounting column 15 is provided with a cylindrical groove 152, and the inner diameter of the cylindrical groove 152 is the same as the outer diameter of the annular plate 22. The protrusion 151 is set inside the cylindrical groove 152, and when the seat cushion 2 is installed, the mounting plate 21 and the annular plate 22 enter the cylindrical groove 152. The specific workflow is as follows; Based on the above embodiment, a cylindrical groove 152 is opened at the upper end of the mounting column 15, and the inner diameter of the cylindrical groove 152 is the same as the outer diameter of the annular plate 22. The protrusion 151 is set inside the cylindrical groove 152. When the seat cushion 2 is installed, the mounting plate 21 and the annular plate 22 enter the cylindrical groove 152, so that after the seat cushion 2 is installed, the sponge layer of the seat cushion 2 can fully contact the elastic metal sheet 18, thereby avoiding the mounting plate 21 and the annular plate 22 from directly contacting the upper end of the mounting column 15. The step between the mounting plate 21 and the annular plate 22 and the mounting column 15 affects the patient's comfort when sitting on the seat, thereby improving the comfort of the seat cushion 2.
