Description

Technical Field

[0001] The invention relates to the field of seats, and in particular to an intelligent lumbar vertebra protection seat based on 3D printing technology. Background Art

[0002] A seat is a kind of seating furniture with a backrest and some also have armrests. It can be divided into car seats, bus seats, family seats, restaurant seats, office seats, etc. With the progress of society and market competition, seats are constantly developing and improving. At the same time, seats are gradually developing in an artistic direction, such as egg-shaped seats, red lip-shaped seats, various massage seats, etc.

[0003] Existing seats provide poor user comfort during use. When people are in a sitting state, the spine is almost the only point where the waist is under pressure, so the pressure will be doubled. At the same time, since the cervical spine is in a forward tilted posture when sitting, it is easy to cause discomfort or injury to the waist of users who sit for a long time. At the same time, the seat is limited to flat seat use during actual use, which is not conducive to user rest and is difficult to meet user needs, thereby reducing the overall practicality of the device.

[0004] In summary, the above structure is very likely to cause discomfort or damage to the waist of users who sit for a long time during actual use. At the same time, the seat itself is difficult to meet the user's usage needs, thereby reducing the overall practicality of the device. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an intelligent lumbar protection seat based on 3D printing technology to solve the technical problem that it is very easy to cause discomfort or damage to the waist of users who sit for a long time, and the seat itself is difficult to meet the user's usage needs, thereby reducing the overall practicality of the device.

[0006] To achieve the above object, the present invention provides the following technical solutions: an intelligent lumbar vertebra protection seat based on 3D printing technology, comprising a seat body and a flexible lumbar support, wherein the flexible lumbar support is located on the inner side of the seat body, an elastic airbag is arranged inside the seat body, an air pipe is connected between the elastic airbag and the flexible lumbar support, a ventilation component is arranged at the bottom of the seat body, and an impeller is arranged to rotate inside the air pipe; One side of the impeller is connected to a transmission mechanism, and the other end of the transmission mechanism is meshed with a threaded rod through a bevel gear. A support plate that cooperates with the threaded rod is slidably arranged on the top of the ventilation assembly in the seat body.

[0007] By adopting the above technical solution, the user squeezes the elastic airbag so that the gas is discharged into the flexible lumbar support through the air pipe. At this time, the flexible lumbar support inflates and is in full contact with the user's lumbar spine. The gas is discharged into the flexible lumbar support through the air pipe. The support plate slides to one side through the engagement of the transmission mechanism and the bevel gear, thereby removing the obstruction to the ventilation component. The temperature and humidity in the seat body are detected by the controller, and the hot and humid gas is discharged from the bottom of the seat body, thereby improving the comfort of the contact surface between the user's buttocks and legs and the seat body.

[0008] The present invention is further configured such that a seesaw is rotatably provided at one end of the support plate, and a limiting mechanism is provided between the seesaw and the support plate, which ensures that the seesaw is located at one end of the support plate at a fixed angle.

[0009] Preferably, when the support plate slides outward, the seesaw is rotated downward as a whole so that the seesaw and the support plate are vertically arranged. In this process, it is ensured that the user's normal sitting posture will not be affected by the support plate. During the user's rest, the seesaw is arranged parallel to the support plate to support the user's legs, which is convenient for the user to rest, meets the user's usage needs, and improves the overall practicality of the device.

[0010] The present invention is further configured such that one end of the transmission mechanism is connected to a positive bevel gear, and a side bevel gear is meshed on one side of the positive bevel gear, and one end of the side bevel gear is connected to a threaded rod.

[0011] Preferably, during the rotation of the transmission mechanism, the positive bevel gear at one end is driven to rotate, and through the engagement with the side bevel gear, the threaded rod on one side of the side bevel gear is rotated, thereby realizing the transmission of the entire device.

[0012] The present invention is further configured such that armrests are arranged on both sides of the seat body, and the outer walls of the armrests are arranged in a rough shape.

[0013] Preferably, when the user sits on the seat body, the armrests can support the user's arms to improve the user's comfort, and the rough setting is convenient for increasing the sliding friction between the objects and the armrests, and the user can place personal belongings on the top of the armrests.

[0014] The present invention is further configured such that a pulley block is detachably provided at the bottom of the seat body, and a self-locking mechanism is provided on the pulley block.

[0015] Preferably, the pulley block allows the user to move the seat body to a designated position, and then the self-locking mechanism is used to limit the position, thereby improving the overall practicality of the device.

[0016] The present invention is further configured such that a controller is provided at the bottom of the seat body at the ventilation component, and the controller is electrically connected to the ventilation component.

[0017] Preferably, the temperature and humidity inside the seat body are detected by a temperature and humidity sensor in the controller. When the temperature and humidity reach a certain value, the ventilation component is activated to discharge hot and humid gas from the bottom of the seat cushion and inhale fresh air from the top of the seat cushion, thereby improving the comfort of the contact surface between the user's buttocks and legs and the seat cushion.

[0018] The present invention is further configured such that a dust collecting plate is detachably provided on the bottom of the support plate, and the dust collecting plate itself is located in an embedded configuration.

[0019] Preferably, the dust collecting plate can absorb dust on the bottom of the seat body in daily life, and the embedded arrangement of the dust collecting plate facilitates the sliding of the support plate in the seat body.

[0020] The present invention is further configured such that the transmission mechanism includes a driving disk, a transmission belt and a driven disk, the driving disk and the driven disk are connected by a transmission belt, one end of the impeller is connected to the driving disk, and one end of the impeller is connected to the spur gear, and the diameter of the driving disk in the transmission mechanism is smaller than the diameter of the driven disk.

[0021] Preferably, during the ventilation process, the impeller in the trachea will be driven to rotate, and the impeller will cause the active disk to rotate accordingly. Through the action of the transmission belt, the driven disk will drive the positive bevel gear to rotate. Since the diameter of the active disk in the transmission mechanism is smaller than the diameter of the driven disk, the driven disk will drive the positive bevel gear to adjust slowly during the rapid rotation of the impeller, thereby ensuring that the support plate effectively slides out of the seat body.

[0022] The present invention is further configured such that a threaded sleeve cooperating with the threaded rod is disposed inside the support plate, and the threaded sleeve itself is detachably disposed.

[0023] Preferably, the support plate can slide stably to one side through the cooperation of the threaded sleeve and the threaded rod, and the threaded sleeve itself can be disassembled to realize regular maintenance work.

[0024] In summary, the present invention mainly has the following beneficial effects: 1. The present invention provides a flexible lumbar support on the inner side of the seat body, and an elastic airbag is installed inside. When the user sits on the seat body, the user squeezes the elastic airbag so that the gas is discharged into the flexible lumbar support through the air pipe. At this time, the flexible lumbar support is inflated by air and is in full contact with the user's lumbar spine, so that the lumbar spine is always relaxed, reducing the pressure on the spine, especially the lumbar part, and further protecting the waist. A ventilation component is provided at the bottom of the seat body, and the temperature and humidity in the seat body are detected by a controller, and the humid and hot gas is discharged from the bottom of the seat body, thereby improving the comfort of the contact surface between the user's buttocks and legs and the seat body.

[0025] 2. The present invention provides an air tube between the flexible lumbar support and the elastic airbag. When the user squeezes the elastic airbag, the gas will be discharged into the flexible lumbar support through the air tube. During this process, the impeller in the air tube will rotate, and the support plate will slide out to one side through the meshing of the transmission mechanism and the bevel gear, thereby releasing the shielding of the ventilation component. When the user stands up later, the gas will return to the elastic airbag through the flexible lumbar support. During this process, the impeller will reverse, and the support plate will slide inward again to reset the ventilation component, thereby completing the shielding of the ventilation component, preventing impurity particles in the air from entering the interior of the seat body through the ventilation component, thereby reducing the service life of the elastic airbag; 3. The present invention has a seesaw plate rotatably arranged at the front end of the support rod. When the support plate slides outward, the seesaw plate is rotated downward as a whole. In this process, it is ensured that the user's normal sitting posture will not be affected by the support plate. During the user's rest, the seesaw plate is arranged parallel to the support plate to support the user's legs, which is convenient for the user to rest, meets the user's usage needs, and improves the overall practicality of the device.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] First embodiment: See also Figure 1-Figure 8 The intelligent lumbar protection seat based on 3D printing technology shown in the figure includes a seat body 1, a flexible lumbar support 3, a transmission mechanism 15, a ventilation mechanism and a support mechanism. A pulley block 2 is detachably provided at the bottom of the seat body 1, and a self-locking mechanism is provided on the pulley block 2. The pulley block 2 facilitates the user to move the seat body 1 to a specified position, and then limits the position through the self-locking mechanism. In this process, the overall practicality of the device is improved, and at the same time, the seat body 1 itself is effectively prevented from slipping. The flexible lumbar support 3 is located at the seat On the inner side of the body 1, an elastic airbag 8 is arranged inside the seat body 1, and an air pipe 10 is connected between the elastic airbag 8 and the flexible lumbar support 3. When the user sits on the seat body 1, the elastic airbag 8 in the seat body 1 is squeezed by the user's own gravity. At this time, the gas in the elastic airbag 8 is discharged into the flexible lumbar support 3 through the air pipe 10. At this time, the flexible lumbar support 3 is inflated by air and fully contacts the user's lumbar spine, so that the lumbar spine is always in a relaxed state, reducing the pressure on the spine, especially the lumbar part, and further realizing the protection of the waist; At the same time, a ventilation component 6 is arranged at the bottom of the seat body 1, and an impeller 9 is arranged to rotate in the air pipe 10. When the user sits on the seat body 1, the gas in the elastic airbag will be discharged into the flexible lumbar support through the air pipe 10. During this process, the impeller 9 in the air pipe 10 will rotate. Since a transmission mechanism 15 is connected to one side of the impeller 9, the transmission mechanism 15 on one side will be driven to rotate. A positive bevel gear 11 is connected to one end of the transmission mechanism 15, and a side bevel gear 12 is meshed on one side of the positive bevel gear 11. One end of the side bevel gear 12 is connected to a threaded rod 13. During the rotation of the transmission mechanism 15, the positive bevel gear 11 at one end will be driven to rotate. Through the meshing with the side bevel gear 12, the threaded rod 13 on one side of the side bevel gear 12 is rotated, thereby realizing the transmission of the entire device, and a support plate 5 cooperating with the threaded rod 13 is slidably arranged at the top of the ventilation component 6 in the seat body 1; At this time, the support plate 5 will slide to one side of the seat body, thereby making the support plate 5 contact and block the ventilation component 6. The temperature and humidity in the seat body 1 are detected by the controller 14, and the humid and hot gas is discharged from the bottom of the seat body 1, thereby improving the comfort of the contact surface between the user's buttocks and legs and the seat body. When the user stands up later, the elastic airbag 8 resets itself, so that the flexible lumbar support 3 exhausts air into the elastic airbag 8 through the air pipe 10. During this process, the impeller 9 in the air pipe 10 will reverse. During this process, the transmission mechanism 15 is engaged with the bevel gear, so that the support plate 5 resets and slides into the seat body 1, thereby completing the shielding of the ventilation component 6 and preventing impurity particles in the air from entering the interior of the seat body 1 through the ventilation component 6, thereby reducing the service life of the elastic airbag 8.

[0031] In the above embodiments, please refer to Figure 1 and Figure 4 By arranging armrests 4 on both sides of the seat body 1 and the outer walls of the armrests 4 being roughened, the user can support his arms through the armrests 4 when sitting on the seat body 1, thereby improving the user's comfort. The roughened setting facilitates increasing the sliding friction between the articles and the armrests 4, and the user can place personal belongings on the top of the armrests 4, thereby increasing the practicality of the seat body 1 itself.

[0032] In the above embodiments, please refer to Figure 2A controller 14 is provided at the bottom of the seat body 1 at the ventilation component 6, and the controller 14 and the ventilation component 6 are electrically connected. The temperature and humidity in the seat body 1 are detected by the temperature and humidity sensor in the controller 14. When the temperature and humidity reach a certain value, the ventilation component 6 is started to discharge the humid and hot gas from the bottom of the seat cushion and inhale fresh air from the upper part of the seat cushion, thereby improving the comfort of the contact surface between the user's buttocks and legs and the seat cushion. In this process, the dehumidification and heat removal effect of the ventilation component 6 is effectively guaranteed.

[0033] In the above embodiments, please refer to Figure 8 The transmission mechanism 15 includes a driving disk, a transmission belt and a driven disk, and the driving disk and the driven disk are connected by a transmission belt. One end of the impeller 9 is connected to the driving disk, and one end of the driven disk is connected to the positive bevel gear 11. The diameter of the driving disk in the transmission mechanism is smaller than the diameter of the driven disk. During the process of the elastic airbag 8 ventilating the flexible lumbar support 3, the impeller 9 in the trachea 10 will be driven to rotate. At this time, the impeller 9 will cause the driving disk to rotate with it. Under the action of the transmission belt, the driven disk drives the positive bevel gear 11 to rotate. Since the diameter of the driving disk in the transmission mechanism 15 is smaller than the diameter of the driven disk, during the rapid rotation of the impeller 9, the driven disk will drive the positive bevel gear 11 to adjust slowly. In this process, the support plate 5 is ensured to slide out of the seat body 1 effectively, which effectively reduces the danger during the sliding process.

[0034] Second embodiment: See also Figure 4 An intelligent lumbar protection seat based on 3D printing technology is shown, and its overall structure is similar to that of Example 1, wherein a seesaw 7 is rotatably arranged at one end of a support plate 5, and a limiting mechanism is arranged between the seesaw 7 and the support plate 5, and the limiting mechanism itself ensures that the seesaw 7 is located at one end of the support plate 5 at a fixed angle, and when the support plate 5 slides outward, the seesaw 7 is rotated downward as a whole so that the seesaw 7 and the support plate 5 are vertically arranged, and in this process, it is ensured that the user's normal sitting posture will not be affected by the support plate 5, and during the user's rest, the seesaw 7 is arranged parallel to the support plate 5 to support the user's legs, which is convenient for the user to rest, meets the user's usage needs, and improves the overall practicality of the device.

[0035] In the above embodiments, please refer to Figure 5The bottom of the support plate 5 is detachably provided with a dust collecting plate, and the dust collecting plate itself is located in an embedded setting. In daily life, the dust collecting plate can absorb the dust at the bottom of the seat body 1. The embedded setting of the dust collecting plate facilitates the sliding of the support plate in the seat body 1, and a threaded sleeve cooperating with the threaded rod 13 is arranged inside the support plate 5, and the threaded sleeve itself is detachably arranged. Through the cooperation of the threaded sleeve and the threaded rod 13, the support plate 5 can slide stably to one side, and the detachable setting of the threaded sleeve itself can realize regular maintenance work on it, thereby ensuring the overall service life of the device.

[0036] The present invention works as follows: when in use, the user sits on the upper surface of the seat body 1, and the elastic airbag 8 in the seat body 1 is squeezed by the user himself. During this process, the gas in the elastic airbag 8 is discharged into the flexible lumbar support 3 through the air pipe 10. At this time, the flexible lumbar support 3 is supported as a whole to fully contact the user's lumbar spine, so that the lumbar spine is always in a relaxed state, reducing the degree of pressure on the spine, especially the lumbar part; At the same time, when the gas passes through the air pipe 10, the impeller 9 in the air pipe 10 will rotate, and under the meshing of the transmission mechanism 15 and the bevel gear, the threaded rod 13 will rotate, so that the support plate 5 in the seat body 1 can slide outward, thereby releasing the support plate 5 from blocking the ventilation component 6. The controller 14 detects the temperature and humidity in the seat body 1, and discharges the humid and hot gas from the bottom of the seat body 1, thereby improving the comfort of the contact surface between the user's buttocks and legs and the seat body 1. When the user stands up later, the gas in the flexible lumbar support 3 will flow back to the elastic airbag 8 through the air pipe 10 through the restoring force of the elastic airbag 8 itself. At this time, the impeller 9 in the air pipe 10 will rotate in the opposite direction, so that the support plate 5 is recovered into the seat body 1, thereby completing the sealing work of the bottom ventilation component 6 again, preventing impurity particles in the air from entering the interior of the seat body 1 through the ventilation component 6, thereby reducing the service life of the elastic airbag 8.
