Description

Technical Field

[0001] The present invention relates to the fields of reading brackets, table lamps, scene models, and toy ornaments, and specifically to a learning bracket that integrates functions of posture correction, lighting, play, and decoration. Background Art

[0002] As far as I know, currently when students are writing homework or studying online, they mostly lay books or tablets flat on the desktop and look at the books and devices at a close distance with their heads down and backs bent in the conventional way. Studying in this posture for a long time will affect eyesight, compress the cervical vertebrae, and bend the spine, which is very harmful to minors who have not yet fully developed. Although there are already reading bracket products on the market that can raise books, they are almost just an inclined table board that can only raise books, cannot twist the viewing angle, has no effect on moving the neck, and is bulky, squeezing the narrow desktop space. With few functions and many side effects, the vast majority of families do not use the existing reading brackets and still adopt bad postures to read and study for a long time.

[0003] In order to solve the difficult-to-control instinct of lowering the head of people, overcome the stiffness brought by studying in a single posture for a long time, integrate various tools required for learning, satisfy the childlike nature of children, and beautify the limited desktop space, a multifunctional learning bracket device can be provided. Summary of the Invention

[0004] To solve the above problems, the present invention proposes a multifunctional tabletop type cyclic swing learning bracket device. The technical solution of the present invention is as follows:

[0005] A tabletop type cyclic swing learning bracket device is composed of a fixed base, an automatic forward and reverse transmission member, a motor, a swing arm, and an equipment support. Through the motor and the automatic forward and reverse transmission member, the swing arm and the equipment support, together with the books or other equipment placed on it, are driven to slowly reciprocate and swing along a predetermined trajectory. When people watch the equipment, they raise their heads and follow the equipment to slowly move their necks, and the above components are integrally installed in the base of a table lamp or a storage cabinet or a scene model to form a multifunctional tabletop type cyclic swing learning bracket device.

[0006] To further refine the above technical solution, the equipment support can be set as a doll to support and fix the equipment and rotate together with the bracket, improving the decorative property while meeting the functional requirements and providing leisure play.

[0007] For further refinement of the above technical solution, the automatic forward and reverse transmission component can be set as an active connecting rod structure composed of a movable slider, a fixed slide rail, an eccentric rotating shaft, and a swing arm transmission end. The eccentric rotating shaft drives the movable slider to rotate to both sides of the fixed slide rail, and a resultant force is formed by the horizontal thrust of the fixed slide rail and the centripetal tension of the eccentric rotating shaft to achieve the automatic steering of the swing arm transmission end and perform cyclic torsional pendulum according to a preset trajectory.

[0008] For further refinement of the above technical solution, the automatic forward and reverse transmission component can be set as follows: the incomplete gear first meshes with the forward rotation gear set on one side of the rotating shaft to drive the inner ring gear of the transmission to achieve forward swing; then it meshes with the steering gear on the other side of the rotating shaft to drive the reverse gear set to drive the inner ring gear of the transmission, forming an automatic forward and reverse gearbox to achieve automatic steering and perform cyclic torsional pendulum according to a preset trajectory.

[0009] For further refinement of the above technical solution, the swing arm can be set as a telescopic and foldable structure so that it can be hidden in the fixed base during non-cyclic torsional pendulum to compress the product volume; when used as a learning support, it is unfolded to extend the torsional pendulum radius and effectively guide the user to move the neck.

[0010] For further refinement of the above technical solution, pen holders, clocks, calculators, and fan functional components can be provided on the fixed base to integrate the devices required for learning together, saving space and improving the utilization rate of the devices.

[0011] For further refinement of the above technical solution, the device support can be set as a doll with twistable joints. The doll-shaped support can change its posture to fix the device according to the size and shape of the fixed device through shapeable flexible bones and joint twisting. Description of the Drawings

[0015] Embodiment 1

[0016] This specific embodiment is: a tabletop type cyclic swinging learning support device in which the fixed base is set as a table lamp, the equipment support is a doll, and a movable connecting rod is used as an automatic forward and reverse transmission member. As Figure 2 、 Figure 3As shown in the figure: 1 is the base lamp of this learning support. Inside the upper frame of the lamp base 1, there is a motor 2. The rotation speed of the motor 2 is 0.2 revolutions per minute, which can drive the eccentric rotating shaft 3a fixed on it to rotate. The transmission end at the upper part of the eccentric rotating shaft 3a is movably inserted into the lower side of the movable slider 3b provided with a groove. The upper side of the groove of the movable slider 3b is also movably inserted with: the swing arm transmission end 5a fixed on the outer wall of the deep groove bearing 4. The other groove of the movable slider 3b is sleeved into the fixed slide rail 3c fixed on the inner wall bottom plate of the bearing, so that the movable slider 3b can slide horizontally around the fixed slide rail 3c. There is a slider positioning part 3d under the fixed slide rail 3c. After the movable slider 3b is sleeved into the fixed slide rail 3c, it is connected to the fixed slide rail 3c with screws to prevent the movable slider 3b from loosening up and down. When the motor 2 rotates, the eccentric rotating shaft 3a twists to drive the movable slider 3b to slide horizontally to one side on the outside of the fixed slide rail 3c. Through the horizontal thrust of the fixed slide rail 3c and the centripetal pull of the eccentric rotating shaft 3a, a resultant force is formed to push the swing arm transmission end 5a to twist clockwise by 150 degrees. After the motor eccentric shaft 3a rotates to the other side of the fixed slide rail 3c, the movable slider 3b moves reversely to the other side inside the fixed slide rail 3c, and the aforementioned resultant force pushes the swing arm transmission end 5a to twist counterclockwise by 150 degrees, realizing the cyclic torsional pendulum of the swing arm. At the other end of the swing arm, there is a front-end positioning bearing 5b, and the extended member 5C of the swing arm is folded and hidden behind the support rod of the lamp. At the end of the swing arm, there is a rear-end positioning bearing 5d, which is connected to a device support 6 in the shape of a plush toy. When the learning support does not swing, the device support 6 is folded behind the lamp and becomes a toy climbing on the lamp. When the device is used as a learning support, the swing arm extended member 5c and the device support 6 are unfolded and extended to the rear of the deep groove bearing 4. Inside the plush device support 6, there is a positioning skeleton 6a made of a metal shaping hose, which can adjust the body posture of the plush device support 6 and clamp and fix an external mobile phone and books in the fixed groove 6b at the feet of the plush toy, forming an image of a plush toy holding a book, and also preventing the device from loosening when the learning support swings. At the rear side of the upper part of the lamp base 1, there is a rear light source 1a, which can illuminate the books at the rear side. At the lower side of the upper part of the lamp base 1, there is an upper light source 1b, and in the middle part, there is a middle light source 1c. The multi-point light sources can effectively avoid the light and shadow interference during reading and writing. At the rear side of the lower part of the lamp base 1, there is a pen holder 7, and at the front side of the lower part, there is an alarm clock 8. Integrating the accessories related to learning into a whole effectively saves space and improves the use efficiency. This tabletop type cyclic torsional pendulum learning support can lift devices such as books and make them twist horizontally at an extremely slow speed. When students read books, their heads instinctively twist around the center of the lamp according to the movement track of the support, exercising the head and neck, and controlling the viewing distance within a reasonable range to protect eyesight. When the support is not used properly, this bionic learning support can be retracted and folded behind the lamp and become a decorative ornament and a toy.

[0017] Embodiment 2

[0018] This specific embodiment is: a tabletop type cyclic torsion pendulum learning support device in which the fixed base is set as a scene model, the device support is a doll, and the steering gearbox is used as an automatic forward and reverse transmission component. As Figure 4 , Figure 5 shown in the figure: 1 is the base of this learning support: a scene model of a two-story building. The second-floor floor of the scene is fixedly connected to the fixed bottom plate 2. There are two suspension pillars 2a in the middle of the fixed bottom plate 2. The middle part of the suspension pillar is connected to the inner wall of the deep groove bearing 3 by screws. On the upper side of the outer wall of the bearing 3, there is a swing arm housing 4a connected by screws. At the lower part of the swing arm housing 4a, there is an inner ring gear 5 with a module of 0.5 and 81 teeth connected. All the accessories connected to the outer wall of the deep groove bearing 3 can rotate horizontally around the axis. The upper part of the suspension pillar 2a is connected to a fixed top plate 2b. A motor 6 is installed on the top plate by screws. The output end of the motor crosses the top plate 2b and is connected to an incomplete gear 7. On the fixed top plate 2b, there are connected by pin shafts: a forward rotation double-layer gear set 8 with 15 teeth of module 0.5 on the upper layer and 30 teeth of module 0.5 on the lower layer; and a reverse rotation double-layer gear set 9 with 12 teeth of module 0.5 on the upper layer and 24 teeth of module 0.5 on the lower layer, and a steering gear 10 with 12 teeth of module 0.5.

[0019] The incomplete gear 7 is a spur gear with a module of 0.5 and 40 teeth, and only 18 teeth required are retained (the remaining tooth positions are cut off). When the motor rotates, the retained tooth positions of the incomplete gear 7 will sequentially mesh separately with the steering gear 10 symmetrically arranged on both sides of the axis and the upper 15 teeth of the forward rotation double-layer gear set 8 (when the retained gear meshes with a certain gear, the incomplete part of the incomplete gear 7 is staggered from the other gear in contact). When the incomplete gear 7 intermittently meshes with the upper 15 teeth of the forward rotation double-layer gear set 8, its lower 30 teeth are permanently meshed with the inner ring gear 5. Since the upper and lower ends are coaxial but have different numbers of teeth, when the upper 15 teeth of the forward rotation double-layer gear set 8 mesh with the retained 18 teeth of the incomplete gear 7, the lower 30 teeth twist 432 degrees and mesh with 36 teeth of the fixed inner ring gear 5 with 81 teeth. Drive the inner ring gear 5 and the swing arm housing 4a fixed thereon to rotate 160 degrees. When the motor 6 continues to rotate a certain angle, the incomplete gear 7 disengages from the upper 15 gears of the forward rotation double-layer gear set 8 and immediately contacts and meshes with the steering gear 10. The steering gear 10 meshes with the upper 12 teeth of the reverse rotation double-layer gear set 9 at the other end at the same time, driving the reverse rotation double-layer gear set 9 to rotate in the other direction. When the upper 12 teeth of the reverse rotation double-layer gear set 9 mesh with the retained 18 teeth of the incomplete gear 7, the lower 24 teeth twist 540 degrees and mesh with 36 teeth of the fixed inner ring gear 5 with 81 teeth, driving the inner ring gear 5 and the swing arm housing 4a fixed thereon to rotate reversely 160 degrees, realizing the overall automatic steering cyclic torsion pendulum of the rear end of the swing arm housing 4a. The lower teeth of the double-layer gears 8 and 9 are permanently meshed and rotated with the fixed inner ring gear 5, but the upper teeth of the double-layer gears 8 and 9 avoid the tooth roots retained by the incomplete gear 7 when not necessary and are in an idling state, and no jamming will occur.

[0020] At the other end of the swing arm housing 4a, there is a front-end positioning bearing 4b. The extension member 4C of the swing arm is folded and hidden into the second-floor ground of the small building scene. At the end of the swing arm extension member 4C, there is a rear-end positioning bearing 4d, which is connected to a device support 11 in the shape of an action figure. When the learning support does not swing, the device support 11 and the swing arm extension member 4c are folded on the second-floor roof, becoming a toy sitting upright on the scene model. When the device is used as a learning support, the swing arm extension member 4c and the device support 11 are unfolded and extended to the rear of the deep groove bearing 3. Inside the action figure device support 11, there is a positioning skeleton 11a made of a metal shaping hose, which can adjust the body posture of the action figure and fix the external mobile phone and book in the fixed groove 11b at the foot of the action figure support 11, forming an action figure image holding a book and swinging around the model, and also preventing the device from loosening when the learning support swings. Around the upper part of the second-floor attic of the scene model base 1, there is a light source 12, which can illuminate the books on the front and rear sides. Various movable furniture, figures, and animal models can be arranged and replaced on the first floor of the scene model base 1 to create an interesting miniature landscape. The whole set of circular swing learning support device has excellent decorative effects and practical comprehensive functions of protecting eyesight, exercising the head and neck, and having fun playing.

[0021] The above is only a specific description of two embodiments of the invention technical solution, but this embodiment is not used to limit the protection scope of the invention. Any equivalent implementation or change that does not depart from the invention technical solution, such as the change in the style of the fixed base, the change in the shape and mechanism of the device support, and the equivalent adjustment of the structure of the automatic forward and reverse transmission member, shall be included in the protection scope of the invention.
