Description

Technical Field

[0001] The invention relates to the field of reading stands and toy ornaments, and in particular to a learning stand with posture correction, playing and decoration functions integrated into one. Background Art

[0002] As far as I know, most students currently lay books or tablets flat on the desktop when doing homework or studying online, with their heads down and backs bent, and look at books and equipment at close range from a single angle. Studying in this posture every day will seriously affect vision, compress the cervical spine, and bend the spine. Although some mobile phone holders and live broadcast holders have appeared on the market, they are almost all for online celebrity live broadcasts and lazy people watching film and television works. There is no learning stand specifically for teenagers who urgently need to correct their sitting posture. They only use support rods to raise the equipment above the desktop. The angle is single and cannot be adjusted dynamically. It is not suitable for reading and online learning, and it is not helpful for correcting sitting posture and cervical spine movement. And due to the limitations of product configuration, most of the current mobile phone holders are mechanical arm structures. Their industrial appearance is incompatible with the home style, affecting the beauty of the home. For existing mobile phone holders that can only support mobile phones, have a single function, are not suitable for learning, and have an inconsistent shape, most parents are unwilling to place them, and students do not like to use them.

[0003] In order to overcome the uncontrollable instinct of people to lower their heads and solve the stiffness caused by long-term single posture learning, the existing mobile phone holders cannot meet the reading and learning functions, parents are reluctant to put them up, and students don't like to use them; we can provide a learning stand device that has posture correction and learning assistance functions, satisfies children's innocence, beautifies the learning space, and has the attributes of decorations and toys. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a bionic learning support device, and the technical solution of the present invention is as follows:

[0005] A bionic learning stand device is composed of a base, double-rod legs, a torsion joint, a supporting spine, a double-rod support arm, a flexible bionic skin, and an equipment fixing clamp. The main technical solution is: the supporting structure of the learning stand is set as a biological skeleton-type frame composed of double-rod legs, a supporting spine, and a double-rod support arm, which is positioned by torsion joint activities and is shaped by a flexible bionic skin wrapped on the outside. The whole set of equipment is fixed to a desktop or a chair back through the base. When studying, it is unfolded into an animal stand holding the equipment, and folded into a toy and decorative ornament when storing.

[0006] To further refine the above technical solution, the flexible bionic skin that wraps and shapes the animal can be set to be detachable and replaceable. On the basis of the same animal skeleton-type bracket system, flexible bionic skins of multiple different types of animals can be preset. Just like changing clothes, one animal shape can be changed into many other animal shapes, which can not only increase the decorative effect, but also can be deformed and played with.

[0007] To further refine the above technical solution, a motor and a transmission device can be provided on the torsion joint to drive the bionic learning bracket to slowly twist and swing along a preset trajectory, changing the position of the device in space. The person's line of sight follows the playback device, and the head passively moves the cervical spine, which can control the viewing distance and protect eyesight.

[0008] To further refine the above technical solution, the base can be set to be clamped and fixed to the chair back, extending from the back to the front and moving in the same direction as the user's neck; it can also be set to be flat on the table, extending from the front to the back, and swinging towards the user.

[0009] To further refine the above technical solution, metal shaped hoses or soft metal materials can be used to make the double-rod legs, supporting spine, and double-rod support arms, so that they can be configured as arbitrarily bent shaped components, and their shapes can be changed and positioned as required.

[0010] The above technical solution is further refined by providing a skull-shaped lamp at the end of the supporting spine, with two eyes serving as light sources to provide lighting for books and further enhance the decorative effect and interest of the toy.

[0011] To further refine the above technical solution, two motors can be set on the torsion joint to drive the bracket to achieve horizontal and vertical torsion and swing respectively, and set multiple motion trajectories; or one motor can be used to control the up, down, left, and right torsion and swing.

[0012] To further refine the above technical solution, components such as the double-rod legs, supporting spine, and double-rod support arms can be set to be foldable and retractable, adjust the length of the limbs, change the shape of the bracket, and adapt to more styles of flexible bionic skins, increase the diversity of the shape, and improve the ornamental and interesting properties.

[0015] Embodiment 1

[0016] This specific embodiment is: The base is set as a clamping type and is a manual bionic learning support device fixed on the back of the chair. As Figure 2 、 Figure 3 shown: There is a U-shaped fixing clip 1a on the base 1 to fix the whole device on the external back of the chair. There is also a folding support rod 1b on the base 1. The other end of the folding support rod 1b is connected through a positioning bearing 1c to a double-rod leg 2 set in the shape of an animal's leg bone. The end of the double-rod leg 2 is connected with an up-and-down positionable torsion joint 3a, which can twist and position the bone-shaped support to the position required in the up-and-down direction. There is a horizontal positionable torsion joint 3b at the rear end of the up-and-down torsion joint 3a, which can twist and position the bone-shaped support to the position required in the left-and-right direction. Behind the positionable torsion joint 3b, there is a support spine 4, which can shape the trunk space of the animal while ensuring the length of the support. Behind the support spine 4, there is a double-rod support arm 5 set in the shape of an animal's front limb bone, further extending the length required by the support. At the end of the double-rod support arm 5, there is a device fixing clip 6, which can clamp a mobile phone, a book, or a tablet computer on the learning support. The double-rod leg 2, the support spine 4, and the double-rod support arm 5 set by imitating the animal bone shape together form a basic bone support system with animal bone characteristics, having the structure, size, configuration, and function of a learning support. And the device is fixed by the device fixing clip 6, and by rotating around the torsion joints 3a and 3b, it shapes a basic bone support system in the shape of an animal holding a book and swaying up, down, left, and right at the waist. Since the limb and trunk bone structures of most reptiles, amphibians, mammals, and birds are roughly similar, and only the head shape, body posture, muscles, skin, hair, color, and clothing are slightly different in appearance, various biological shapes can be shaped on the same bone only by adjusting the filled leather bag. On the outside of the basic bone support system of the present invention, there is a preset flexible bionic leather bag 7, which can adjust its posture conforming to the changes of the bone, and turn the whole support system into a cute animal ornament and a play toy. There is a magic tape 7a on the inner side of the flexible bionic leather bag 7, so that the flexible bionic leather bag 7 can be detached and replaced to change into a completely different shape, such as Figure 2Based on the same set of bone scaffolds, two bionic states of the flexible bionic skin are demonstrated by replacing it with an elk and a cat respectively (for display purposes, only one set of scaffolds is actually available at the same time), which can prevent aesthetic fatigue and continuously bring forth new ideas.

[0017] At the front end of the supporting spine 4, a telescopic rod 8 in the shape of a cervical vertebra can be provided, which can be extended and shortened according to the length of the neck of the bionic animal. For example, Figure 2 As shown in the figure, when the bionic animal in the lower figure is a cat, the neck contracts, and when the bionic animal in the upper figure is an elk, the neck extends. At the end of the cervical vertebra rod 8, a lamp 9 imitating the skull is also provided, and two eyes are set as light sources to provide illumination for devices such as books at the end of the device clamp 6. The double-rod legs 2, the supporting spine 4, and the double-rod support arms 5 are made of metal-shaped flexible hoses into arbitrarily bendable and shapeable components, so that the limbs and spine of the bionic scaffold can bend and move, further adjusting the positioning accuracy of the scaffold and the fun of being a toy ornament. Figure 2 The lower side shows the shape of a running cat, and the upper side shows the shape of a standing elk, and various postures can be adjusted arbitrarily. For example, Figure 2 As shown, when the bionic learning scaffold device is not used properly as a scaffold, it can be retracted and folded to the back of the chair through the folding support rod 1b and the positioning bearing 1c on the base 1, turning into a bionic animal toy climbing on the back of the chair, and the waist and limbs can all be moved and played with, combining practicality, aesthetics, and fun.

[0018] Embodiment 2

[0019] This specific embodiment is: This specific embodiment is: The base is set as a clamping type, and a double-motor automatic swinging bionic learning scaffold device fixed on the back of the chair. For example, Figure 4 、 Figure 5As shown in the figure: There is a U-shaped fixed clip 1a on the base 1 to fix the whole device on the external chair back. There is also a folding support rod 1b on the base 1, and the other end of which is connected with a double-rod leg 2 in the shape of an animal's leg bone through a positionable bearing 1c. The end of the double-rod leg 2 is fixedly connected with the inner wall of the deep groove bearing 3 by screws. The outer wall 3a of the deep groove bearing 3 serves as a suspension frame, enabling all the accessories connected thereto to rotate horizontally around the deep groove bearing. An inner ring gear 4 with a module of 0.5 and 72 teeth is fixed at the upper end of the outer wall 3a of the deep groove bearing. A horizontal motor 5 is arranged in the hollow space of the double-rod leg 2, which drives a spur gear 6 with a module of 0.5 and 30 teeth to mesh with the inner ring gear 4. Each rotation can drive the inner ring gear 4, the outer wall 3a of the deep groove shaft, and the transmission bottom plate 7 fixedly connected thereto to horizontally twist by 150 degrees. A vertical and horizontal motor 8 is connected to the transmission bottom plate 7 by screws to drive a horizontally arranged spur gear 9 with a module of 0.5 and 20 teeth to rotate horizontally. A torsion bracket 10 is also fixedly arranged on the transmission bottom plate 7. Through the holes on both sides of the torsion bracket 10, a vertically rotating spur gear 11 with a module of 0.5 and 20 teeth is installed. The horizontal spur gear 9 rotates horizontally under the drive of the motor 8, meshes with and drives the spur gear 11 to rotate vertically, and is transmitted to the support spine 12 outside the torsion bracket through a coupling to realize the vertical torsion of the remaining parts of the bracket. Behind the support spine 12, there is a double-rod support arm 13 in the shape of an animal's front limb bone. At the end of the double-rod support arm 13, there is an equipment fixing clip 14. Outside the above basic bone bracket system, there is a preset flexible bionic skin 15 and a magic tape 15a for facilitating the replacement of the skin. At the front end of the support spine 12, there is a telescopic rod 16 in the shape of a cervical vertebra and a lamp 17 imitating the skull to provide illumination for devices such as books at the end of the equipment fixing clip 14. This double-motor bionic learning bracket device can separately set the rotation speed, forward and reverse rotation, and rotation sequence of each motor to achieve different motion trajectories, and the torsion speed of the motor is lower than 0.5 revolutions per minute, and the torsion speed is very slow. When people cannot perceive the torsion, their line of sight follows the playback device, and their heads instinctively twist according to the motion trajectory of the bracket, which can control the viewing distance within a reasonable range, protect eyesight, and exercise the head and neck. When the bionic learning bracket is used improperly, it can be retracted and folded behind the chair back to become a decorative ornament and a simulation toy.

[0020] Embodiment 3

[0021] This specific embodiment is: A single-motor automatic swing bionic learning bracket device with a clamping base fixed on the chair back. As Figure 6 、 Figure 7 、 Figure 8As shown in the figure: A U-shaped fixing clip 1a is provided on the base 1 to fix the whole set of devices on the external backrest. A folding support rod 1b is also provided on the base, and the other end thereof is connected through a positionable bearing 1c to a double-rod leg 2 configured in the shape of an animal's leg bone. The end of the double-rod leg 2 is fixedly connected to the outer wall of the deep groove bearing 3 by screws. A fixed inner ring gear 4 is connected below the outer wall of the deep groove bearing 3. The fixed inner ring gear 4, the outer wall of the bearing 3, and the double-rod leg 2 form a fixed platform that will not twist or swing. The inner wall 5 of the deep groove bearing 3 is used as a rotating suspension frame, enabling all the accessories connected thereto to rotate horizontally around the axis. Inside the inner wall space of the deep groove bearing 3, avoiding the position where the gear rotates, two suspension struts 5a are connected to the inner wall of the deep groove bearing by screws. A bottom plate 5b is connected below the suspension struts 5a. A motor 6 is installed at the lower part of the bottom plate 5b by screws. The output end of the motor 6 crosses the bottom plate 5b and is connected to an incomplete gear 7. A double-layer gear set 1236 with 12 teeth of 0.5 module on the upper layer and 36 teeth of 0.5 module on the lower layer, and a double-layer gear set 1030 with 10 teeth of 0.5 module on the upper layer and 30 teeth of 0.5 module on the lower layer are connected to the bottom plate 5b by pins. A suspension housing 5c is connected to the middle of the suspension struts 5a. Through the holes on both sides of the suspension housing 5c, two symmetrically installed bevel gears 8a and 8b with 20 teeth of 0.5 module rotating up and down are installed inside, and a coaxial support spine 9 is installed outside. Above the suspension struts 5a, a top plate 5d is connected. A steering gear 10 with 10 teeth of 0.5 module is connected to the top plate 5d by a pin.

[0022] The incomplete gear 7 is a complex special-shaped gear. On the plane, it appears as a spur gear with a module of 0.5 and 64 teeth, and only 15 required teeth are retained (the remaining tooth positions are cut off). On the elevation, it appears as a protruding bevel gear with 60 teeth, and only 5 required teeth are retained (the remaining tooth positions are ground flat). When the motor rotates in the range of 0 - 145 degrees, the 15 tooth roots reserved in the plane space of the incomplete gear 7 mesh with the 12 teeth at the upper end of the 1236 gear set. At the same time, the 36 teeth at the lower end of the 1236 gear set are meshed with the fixed inner ring gear 4 for driving. Since the upper and lower ends are coaxial but have different numbers of teeth, when the 12 teeth at the upper end mesh and rotate 15 teeth, the 36 teeth at the lower end twist 450 degrees, so that it meshes with 45 teeth of the 108-tooth fixed inner ring gear 4. Since the inner ring gear 4 is fixed, the entire suspension system is fixed on the inner wall 5 of the rotatable deep groove shaft 3. Under the reaction force driven by the motor, the accessories on the suspension frame (including the motor, flexible wire, gear set, suspension housing, and supporting spine) rotate 150 degrees as a whole (equivalent to a car with an engine driving a fixed road surface and moving in the opposite direction under the reaction force). When all the 15 tooth roots of the retained teeth of the incomplete gear 7 have rotated and there is no more tooth root meshing, in order to prevent the bracket from reversing, a positioning pin 11 is provided under the bottom plate 5b. After it rotates with the suspension frame, it is snapped into the fixed spring 11b arranged inside the right side of the double-rod leg (the bracket rotates horizontally without external force, and the spring can achieve horizontal positioning). When the motor continues to rotate in the range of 145 - 180 degrees, the 5 tooth roots of the bevel gear reserved in the elevation space of the incomplete gear 7 mesh with 5 teeth of the 20-tooth bevel gear 8b on the upper right side, driving the bevel gear set 8a, 8b and the supporting spine 9 to twist upward by 90 degrees at the same time. On the coaxial side between the two bevel gears 8a, 8b, an arched positioning piece 12 with four sides cut into straight edges is provided. When the bevel gear set does not need to rotate: the straight edge of the arched positioning piece 12 and the upper plane of the incomplete gear 7 are vertically pressed against each other face to face during the horizontal rotation process, and there is no space for the bevel gear set to rotate, realizing the positioning of the supporting spine 9 in the up and down directions. When the 5 tooth roots of the bevel gear reserved in the elevation space of the incomplete gear 7 rotate to the lower side of the bevel gear 8b, the preset groove 12b on the plane of the incomplete gear 7 also rotates to the lower side of the positioning piece 12 at the same time. The right angle that was originally pressed against the upper plane of the incomplete gear 7 just turns into the groove 12b, enabling the bevel gear set to rotate. After rotating 90 degrees together with the bevel gear set, another straight edge of the positioning piece 12 re-contacts the plane of the incomplete gear 7 without a groove vertically, positioning the supporting spine 9 at a position 45 degrees upward (starting to rotate at 45 degrees downward).The motor continues to rotate in the range of 180 - 325 degrees. The 15 - tooth root retained in the plane space of the incomplete gear 7 comes into contact and meshes with the steering gear 10. The steering gear 10 simultaneously meshes with the upper - layer 10 teeth of the 1030 double - layer gear set at its other end, driving the 1030 double - layer gear set to rotate in the other direction. The upper - end 10 teeth mesh with 15 teeth, and the lower - end 30 teeth twist 540 degrees and mesh with 45 teeth of the fixed inner - ring teeth 4 with 108 teeth. At the same time, under the pulling force of the torsion, the positioning stud 11 disengages from the snap ring 11b and rotates 150 degrees in the reverse direction as a whole with all the accessories on the suspension frame, and finally snaps into the fixed snap ring 11a inside the left side of the double - rod leg 2, realizing the repeated cyclic torsion swing of all the accessories at the rear end of the bracket in the horizontal direction. (The lower - layer teeth of the double - layer gears 1030 and 1236 are permanently meshed and rotated with the fixed inner - ring teeth 4, but when their upper - layer teeth do not need to mesh, although they are rotating, they avoid the tooth roots retained by the incomplete gear 7 and are in an idling state, which will not cause jamming.) When the motor rotates in the range of about 325 - 360 degrees, the 5 - tooth bevel gear retained in the vertical space of the incomplete gear 7 rotates to the left side of the axis, and the preset groove 12a on its upper plane also turns to the lower side of the arched positioning piece, driving the 8a bevel gear on the left side to rotate downward by 90 degrees, returning to the starting point and automatically positioning. This realizes the repeated cyclic torsion swing of the whole bracket system supporting the rear end of the spine 9 up and down.

[0023] Similar to the double - motor bionic learning bracket, a double - rod support arm 13 is provided at the rear end of the spine 9 support. At the end of the double - rod support arm 13, a device fixing clip 14 is provided. Outside the above - mentioned basic bone bracket system, a preset flexible bionic skin 15 and a magic fastener for facilitating the replacement of the skin are wrapped. At the front end of the spine 9 support, a telescopic rod 16 in the shape of the cervical vertebra and a lamp 17 imitating the skull are provided to provide illumination for devices such as books at the end of the device fixing clip 14. The single - motor bionic learning bracket can also realize the function of cyclic torsion swing, with a fixed torsion - swing trajectory, and also has the functions of protecting eyesight and exercising the head and neck. And when the bracket is used improperly, it can be retracted and folded behind the chair back, turning into a decorative ornament, a simulation toy, beautifying the home and for decoration and play.

[0024] The above - mentioned embodiment solutions are only for enabling the majority of readers to more specifically understand the content of the present invention, and do not represent all of the invention. Any equivalent implementation or change that does not deviate from the technical solution of the present invention, such as the shape adjustment of the bone bracket, the equivalent adjustment of the torsion joint and the flexible bionic skin, should be included in the protection scope of the invention. Any implementation of the solution protected by the claims of this invention is an infringement act.
