Description

Technical Field

[0001] This invention relates to the field of children's furniture design technology, specifically a tracked vertical circulating three-dimensional children's bookshelf. Background Technology

[0002] Reading is a crucial activity in a child's development, and children's bookshelves, as an important tool to support children's reading, play an indispensable role. Children's bookshelves help stimulate children's interest in reading. Neatly arranging books on a bookshelf creates a dedicated reading area for children, allowing them to experience the atmosphere of reading and thus being more willing to engage with books, thereby stimulating their interest in reading. However, in the process of developing this invention, the inventors discovered that at least the following problems remain unresolved in the existing technology:

[0003] 1. Traditional children's bookshelves often adopt a stable design. Some children's bookshelves can be moved by installing casters at the bottom. However, it is not easy for children to cross the threshold when moving the bookshelf in this way, which is very strenuous.

[0004] 2. Traditional children's bookshelves are prone to tilting and collapsing during movement, making them inconvenient for children to organize. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as: traditional children's bookshelves often adopt a stable design, and some children's bookshelves move by installing casters at the bottom. However, when children use this method to move the bookshelf, it is inconvenient for them to cross the threshold, which is very strenuous. Traditional children's bookshelves are also prone to tilting and collapsing due to shaking when storing a small number of books, which is not convenient for children to organize.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A tracked vertical circulating three-dimensional children's bookshelf includes a load-bearing plate and a bottom moving structure. The bottom moving structure is fixed to the bottom of the load-bearing plate, and multiple hydraulic cylinders are fixed to both sides of the top of the load-bearing plate. The top of the hydraulic cylinders is rotatably connected to a circular frame via a rotating connecting seat. A counterweight is fixed to the bottom of the circular frame. The bottom moving structure includes a chassis, a track, transmission wheels, and a motor. Multiple transmission wheels are rotatably connected to both sides of the chassis, and the track is sleeved around the periphery of the multiple transmission wheels. Multiple motors are installed inside the chassis, and the output ends of the motors are connected to the transmission wheels. Limit frames are installed at the four corners inside the chassis, and electric push rods are fixedly installed inside the limit frames. One end of the electric push rod passes through the chassis and is fixed to a rotating seat. A baffle is rotatably connected to the periphery of the rotating seat. Multiple book storage structures are connected inside the circular frame via a vertical circulating structure.

[0008] Preferably, the book storage structure includes an adjustment groove, an adjustment bolt, an adjustment plate, and a book holder. The adjustment plate is slidably installed inside the book holder, the front end of the book holder has an adjustment groove, and the bottom of the front end of the adjustment plate is connected to the adjustment bolt.

[0009] Preferably, the vertical circulation structure includes a transmission chain, an auxiliary tensioning wheel, and connecting columns. The auxiliary tensioning wheel is fixed at the four corners inside the return frame. The transmission chain is sleeved around the auxiliary tensioning wheel, and multiple connecting columns are fixed at equal intervals on the inner side of the transmission chain.

[0010] Preferably, a book-placing robot is rotatably connected to the periphery of each of the connecting columns, and a locking block is fixed on the side of the book-placing robot away from the transmission chain.

[0011] Preferably, the book storage structure further includes locking slots, which are provided on both sides of the book holder and are adapted to locking blocks.

[0012] Preferably, the vertical circulation structure further includes a reduction motor and a transmission gear. The reduction motor is fixed on one side of the loop frame, and a transmission gear that passes through the loop frame is installed on one side of the reduction motor. The transmission gear is adapted to the transmission chain.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. During use, the device can be moved according to needs, and has a certain climbing function. It can cross thresholds of a certain height without tipping over, making it easy for children to use.

[0015] 2. When storing a small number of books, the device of the present invention can limit the position of the books on the book rack by squeezing and clamping, so as to avoid tilting and collapse due to shaking.

[0028] Example 1

[0029] like Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown, the present invention proposes a tracked vertical circulating three-dimensional children's bookshelf, including a load-bearing plate 7 and a bottom moving structure 8. The bottom moving structure 8 is fixed to the bottom of the load-bearing plate 7, and multiple hydraulic cylinders 3 are fixed to both sides of the top of the load-bearing plate 7. The top of the hydraulic cylinders 3 is rotatably connected to a circular frame 1 through a rotating connecting seat 2. A counterweight block 6 is fixed to the bottom of the circular frame 1. The bottom moving structure 8 includes a housing 801, a track 802, a transmission wheel 803, and a motor 804. Multiple transmission wheels 803 are rotatably connected to both sides of the housing 801. The track 802 is sleeved around the multiple transmission wheels 803. Multiple motors 804 are installed inside the housing 801. The output end of the motor 804 is connected to the transmission wheel 803. Limiting frames 14 are installed at the four corners inside the housing 801. Electric push rods 13 are fixedly installed inside the limiting frames 14. One end of the electric push rod 13 passes through the housing 801 and is fixed to a rotating seat 12. A baffle 9 is rotatably connected to the periphery of the rotating seat 12.

[0030] In this embodiment, the motor 804 starts running after being energized. The power generated by the output of the motor 804 is converted by the commutator and drives the transmission wheel 803 to rotate. During the rotation of the transmission wheel 803, the track 802 is rotated, thereby moving the position of the device. When the bottom moving structure 8 encounters a threshold during its movement, the baffle 9 blocks the bottom moving structure 8 from the threshold. When only one baffle 9 is in contact with the threshold, the bottom moving structure 8 cannot continue to move forward. However, driven by the track 802, the bottom moving structure 8 will rotate and move around the baffle 9 that is already in contact with the threshold until the two baffles 9 in front of the bottom moving structure 8 are in contact with the threshold at the same time. At this time, the bottom moving structure 8 is in a state of parallel rotation with the threshold. The motor 804 reverses, causing the bottom moving structure 8 to move backward a certain distance. The hydraulic cylinder 3 lifts the return frame 1 through the rotating connecting seat 2. The counterweight 6 moves upward under the action of the rotating frame 1, eventually maintaining a certain distance from the load-bearing plate 7. After the electric push rod 13 is energized, it drives the rotating seat 12 to retract. During the retraction of the rotating seat 12, it drives the baffle 9 to rotate around the chassis 801 as the fulcrum. When the baffle 9 is horizontal with the ground, the electric push rod 13 stops retracting, the motor 804 rotates forward, and the bottom moving structure 8 begins to move forward under the drive of the track 802 to climb over the threshold. During the process of climbing over the threshold, with the added weight of the counterweight 6, the rotating frame 1 always maintains a nearly vertical state with the ground using the rotating connecting seat 2, reducing the swaying amplitude of the rotating frame 1, thereby preventing the device from tipping over during the process of climbing over the threshold. After the bottom moving structure 8 has completely passed the threshold, the hydraulic cylinder 3 begins to retract, causing the counterweight 6 to fall back to the top of the load-bearing plate 7, preventing the rotating frame 1 from rotating using the rotating connecting seat 2, thus making the device more stable.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the present invention proposes a tracked vertical circulation three-dimensional children's bookshelf. Compared with Embodiment 1, this embodiment further includes: the interior of the U-shaped frame 1 is connected to multiple book storage structures 5 via a vertical circulation structure 4. Each book storage structure 5 includes an adjustment groove 502, an adjustment bolt 503, an adjustment plate 504, and a book support 505. The front end of the book support 505 has an adjustment groove 502, and the adjustment plate 504 is slidably installed inside the book support 505. The bottom of the front end of the adjustment plate 504 is connected to the adjustment bolt 503. The book storage structure 5 also includes a snap-fit ​​groove 501, which is located on both sides of the book support 505 and is adapted to the snap-fit ​​block 11. The vertical circulation structure 4 also includes... The geared motor 401 and the transmission gear 402 are fixed on one side of the retractable frame 1. The transmission gear 402, which passes through the retractable frame 1, is installed on one side of the geared motor 401 and is adapted to the transmission chain 403. The vertical circulation structure 4 includes a transmission chain 403, an auxiliary tension wheel 404, and connecting posts 405. The auxiliary tension wheel 404 is fixed at the four corners inside the retractable frame 1. The transmission chain 403 is sleeved around the auxiliary tension wheel 404. Multiple connecting posts 405 are fixed at equal intervals on the inner side of the transmission chain 403. The book-placing robot 10 is rotatably connected to the periphery of each connecting post 405. A locking block 11 is fixed on the side of the book-placing robot 10 away from the transmission chain 403.

[0033] In this embodiment, after the reduction motor 401 is powered on, its output end drives the transmission gear 402 to rotate synchronously. During the rotation of the transmission gear 402, the transmission chain 403 is driven to rotate by the toothed platform inside the transmission chain 403 that is adapted to it. During the rotation of the transmission chain 403, it can drive the connecting column 405 to move synchronously. During the movement of the connecting column 405, it drives the book-placing robot arm 10 to rotate. After the book-placing robot arm 10 rotates to the designated position, the book storage structure 5 is manually installed between the book-placing robot arm 10, and the snap-fit ​​block 11 is installed into the snap-fit ​​groove 501, thereby completing the assembly. Here, since the connecting column 405 and the book-placing robot arm 10 structure are rotatably connected, the coefficient of friction is small, and the book storage structure 5 itself has a certain weight. Therefore, during the rotation of the transmission chain 403, the book storage structure 5 remains stable during movement. After the book storage structure 5 is installed, the user can place the books to be stored into the book holder 505. When the thickness of the placed book is less than the internal space of the book holder 505, the adjusting plate 504 is manually pushed after placement to make the adjusting plate 504 fit against the side of the book. After fitting, the adjusting bolt 503 is manually adjusted. When one end of the adjusting bolt 503 contacts the inner wall of the adjusting groove 502, the position of the adjusting plate 504 on the book holder 505 is limited, thereby limiting and protecting the books inside the book holder 505 and preventing the books from tilting or collapsing during storage. This process is repeated to complete the organization and storage of books.

[0034] When using the three-dimensional children's bookshelf of the present invention, the book storage structure 5 is manually installed between the book-placing robotic arm 10, and the locking block 11 is installed inside the locking slot 501. After the reduction motor 401 is powered on, its output end drives the transmission gear 402 to rotate synchronously. During the rotation of the transmission gear 402, the transmission chain 403 is driven to rotate by the toothed platform inside the transmission chain 403 that is adapted to it. During the rotation of the transmission chain 403, the connecting column 405 can be driven to move synchronously. During the movement of the connecting column 405, the book-placing robotic arm 10 is driven to rotate. After the book-placing robotic arm 10 rotates to the designated position, it sequentially moves the book storage structure 5. After assembly, once the book storage structure 5 is installed, the user can place the books to be stored into the book holder 505. When the thickness of the placed books is less than the internal space of the book holder 505, the adjusting plate 504 is manually pushed after placement to make the adjusting plate 504 fit against the side of the books. After fitting, the adjusting bolt 503 is manually adjusted. When one end of the adjusting bolt 503 contacts the inner wall of the adjusting groove 502, the position of the adjusting plate 504 on the book holder 505 is limited. After restarting the reduction motor 401, the books are placed into the book storage structure 5 in sequence for storage. The position of the device can be moved using the bottom moving structure 8.

[0035] When the three-dimensional children's bookshelf of the present invention is moved, it is in the following usage state: Figure 1 and Figure 5 As shown, when there is no threshold in the forward direction of the bottom moving structure 8, or when the threshold height is lower than the distance between the bottom surface of the baffle 9 and the ground, the motor 804 is powered on and starts to run. The power generated by the output end of the motor 804 is converted by the commutator and drives the transmission wheel 803 to rotate. During the rotation of the transmission wheel 803, the track 802 is driven to rotate, thereby realizing the movement of the device position.

[0036] Operating State 2: When the direction of travel of the bottom moving structure 8 has no threshold, and the threshold height is higher than the distance between the bottom surface of the baffle 9 and the ground, when the bottom moving structure 8 encounters a threshold during its movement, the baffle 9 blocks the bottom moving structure 8 from the threshold. When only one baffle 9 is in contact with the threshold, the bottom moving structure 8 cannot continue to move forward. However, driven by the track 802, the bottom moving structure 8 will rotate around the baffle 9 that is already in contact with the threshold until both baffles 9 in front of the bottom moving structure 8 simultaneously contact the threshold. At this point, the bottom moving structure 8 is in a state of horizontal alignment with the threshold. The motor 804 reverses, causing the bottom moving structure 8 to move backward a certain distance. The hydraulic cylinder 3 rotates the baffle. The connecting seat 2 lifts the rotating frame 1, and the counterweight 6 moves upward simultaneously under the action of the rotating frame 1, eventually maintaining a certain distance from the load-bearing plate 7. After the electric push rod 13 is powered on, it drives the rotating seat 12 to retract. During the retraction of the rotating seat 12, it drives the baffle 9 to rotate around the chassis 801 as the fulcrum. When the baffle 9 is horizontal with the ground, the electric push rod 13 stops retracting, the motor 804 rotates forward, and the bottom moving structure 8 begins to move forward under the drive of the track 802 to climb over the threshold. During the process of climbing over the threshold, with the added weight of the counterweight 6, the rotating frame 1 always maintains a nearly vertical state with the ground by using the rotating connecting seat 2, reducing the swaying amplitude of the rotating frame 1, thereby preventing the device from tipping over during the process of climbing over the threshold.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
