Description

Technical Field

[0001] This application relates to the field of amusement facility technology, and in particular to a child-friendly smart street playground device. Background Technology

[0002] With the continuous advancement of urban construction in my country, children, as an important part of the urban population, are receiving increasing attention from society regarding their growth environment and activity needs. The state has clearly stated that it will vigorously construct children's activity venues and related supporting facilities, and incorporate them into the overall urban development plan, aiming to provide children with safe, suitable, and diverse activity spaces to support their physical and mental health development. Currently, most existing children's playground facilities in cities consist of traditional equipment such as slides, seesaws, and swings. However, these facilities suffer from limitations in functionality and fixed form, making it difficult to effectively stimulate children's sustained interest and creativity. Furthermore, once installed, they typically occupy a large area, and due to the limitations of fixed installation methods, moving and relocating them is cumbersome, making it impossible to flexibly move or relocate them according to dynamic adjustments in municipal construction plans. Therefore, existing children's playground installations have low applicability and are unable to meet the dynamic needs of urban spaces, exhibiting significant shortcomings. Utility Model Content

[0003] To improve the applicability of children's playground devices, this application provides a child-friendly smart street playground device.

[0004] The present application provides a child-friendly smart street playground device using the following technical solution: A child-friendly smart playground device includes seven modules, namely five isosceles right-angled triangle modules, one rectangular module and one parallelogram module. The seven modules are spliced ​​together to form a tangram structure, and the modules are connected by magnetic adsorption.

[0005] By adopting the above technical solutions, diverse play forms can be created through different combinations of modules during children's play, enriching their play experience and stimulating their interest and creativity. At the same time, the playground equipment can be disassembled and combined according to actual needs. When it is necessary to move or relocate, each module can be disassembled and moved individually, reducing the difficulty of moving and relocating. The overall shape and placement of the equipment can be adjusted according to municipal construction plans, reducing dependence on fixed installation space and thus improving the applicability of children's playground equipment.

[0006] Optionally, the module has a storage slot, and a backrest assembly is provided in the storage slot. The backrest assembly includes a back panel rotatably connected in the storage slot. The module has a support slot, and when the back panel rotates 180°, the back panel is inserted into the support slot.

[0007] By adopting the above technical solution, when the back panel is needed, the user can rotate the back panel out of the storage slot and place it in the support slot. At this time, the back panel unfolds to provide reliable support for children, improving comfort during play. When the back panel is not needed, it can be rotated and stored in the storage slot, avoiding the back panel component from occupying extra space. The back panel component provides a temporary resting place for children's play, better meeting the needs of children in different play scenarios, thereby further improving the applicability of children's playground equipment.

[0008] Optionally, the backrest assembly also includes a sponge lumbar support, which is detachably connected to the back panel via Velcro. When the back panel is stored inside the storage slot, the lumbar support is positioned in the empty portion of the storage slot.

[0009] By adopting the above technical solution, when using the backrest assembly, the sponge lumbar support is first removed from the storage slot, then the back panel is turned out and the sponge lumbar support is attached to the back panel. The sponge lumbar support can conform to the curve of the child's waist to provide comfortable support, further improving the comfort when leaning against it. When the backrest assembly is not in use, the sponge escapes to fill the gap in the storage slot, reducing the risk of children bumping or tripping due to the gap in the storage slot when playing on the module surface, thus improving the safety of children during play.

[0010] Optionally, the bottom surface of the module is provided with a receiving groove, and a connecting frame is provided in the receiving groove. Universal wheels are provided on both sides of the connecting frame.

[0011] By adopting the above technical solution, when it is necessary to move a module, the user can easily push the module to move by taking advantage of the rolling characteristics of the casters, which reduces the difficulty of moving a single module.

[0012] Optionally, the connecting frame is rotatably disposed within the receiving groove, the connecting frame is provided with a rotating shaft, and the inner side wall of the receiving groove is provided with a rotating groove that rotatably engages with the rotating shaft. When the connecting frame rotates to a horizontal position, the caster wheel is disengaged from the ground, and the rotating shaft is provided with a rotation limiting component for restricting rotational movement.

[0013] By adopting the above technical solution, when the module does not need to be moved, the connecting frame rotates to a horizontal position, causing the casters to leave the ground. Then, the horizontal position of the connecting frame is fixed by the rotation limiting component. This allows the bottom surface of the module to be stably attached to the ground, reducing the shaking caused by the casters contacting the ground, thereby reducing the risk of accidents caused by the device shaking during use. When moving, the connecting frame is rotated to a vertical position and fixed by the rotation limiting component. This reduces the impact of the casters accidentally retracting on the movement operation and improves the smoothness of the transfer process.

[0014] Optionally, the rotation limiting component includes a drive shaft slidably sleeved on the outer surface of the rotating shaft. The drive shaft has a limiting groove along the axial direction. A limiting block is slidably connected to the limiting groove on the rotating shaft. The limiting block is fixedly sleeved on the outer surface of the drive shaft. The limiting block is a cube. A square groove is formed on the inner wall of one end of the rotating groove, which slides with the limiting block. A circular groove is formed on the inner wall of the other end, which rotates with the limiting block. The circular groove communicates with the square groove. A retaining spring is provided in the circular groove. The elastic force of the retaining spring drives the limiting block to engage in the square groove.

[0015] By adopting the above technical solution, when the connecting frame needs to be rotated, the drive shaft is pulled outward to compress the clamping spring. The drive shaft drives the rotation limiting block from the square groove into the round groove. At this time, the rotation of the limiting block and the drive shaft is not restricted by the square groove. When the drive shaft rotates, it drives the rotating shaft to rotate through the limiting block and the limiting groove, thereby realizing the rotation of the connecting frame. After the connecting frame is rotated into place, the drive shaft is released, and the elastic force of the clamping spring drives the limiting block to insert into the square groove. At this time, the square groove restricts the rotation of the limiting block and the drive shaft, thereby restricting the rotation of the rotating shaft and fixing the position of the connecting frame.

[0016] Optionally, the edges of the module are designed with rounded transitions.

[0017] By adopting the above technical solution, the rounded edge can effectively eliminate the sharp corners of the module edge, avoiding accidental injuries such as bumps and scratches caused by children colliding with the module edge while they are active, climbing or playing on the playground equipment, thus greatly improving the safety of the equipment.

[0018] Optionally, the module is made of polycarbonate sheet.

[0019] By adopting the above technical solutions, polycarbonate sheets have high strength and toughness, and can withstand the impact and squeezing of children during play, ensuring the structural stability and service life of the modules; polycarbonate sheets are lightweight, which can reduce the weight of individual modules, and with the addition of casters and other structures, they are easier to handle and move.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. This application proposes a playground facility composed of seven modules. When children play, the different combinations of the modules can create diverse play forms, enriching their play experience and stimulating their interest and creativity. At the same time, the playground device can be disassembled and combined according to actual needs. When it needs to be moved or transferred, each module can be disassembled and moved individually, reducing the difficulty of moving and transferring. The overall shape and placement of the device can be adjusted according to municipal construction plans, reducing the dependence on fixed installation space, thereby improving the applicability of the children's playground device. 2. This application provides reliable support for children by setting up a backrest assembly and unfolding the back panel, thereby improving comfort during play. 3. This application, by setting up a connecting frame, casters, and a rotation limiting component, allows the connecting frame to rotate to a horizontal position when the module does not need to move, causing the casters to detach from the ground. The rotation limiting component then secures the horizontal position of the connecting frame, ensuring that the bottom surface of the module can stably contact the ground and reducing the shaking caused by the casters contacting the ground. This reduces the risk of accidents to children due to device shaking during use. When moving, the connecting frame is rotated to a vertical position and secured by the rotation limiting component, thus reducing the impact of accidental retraction of the casters on the movement operation and improving the smoothness of the transfer process.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a child-friendly smart playground device.

[0028] Reference Figure 1 A child-friendly smart playground device includes seven modules 1, each module 1 being made of polycarbonate sheet with high strength and toughness. The polycarbonate sheet is lightweight, which reduces the weight of a single module 1 and facilitates the handling and transfer of the module 1.

[0029] Reference Figure 1 The seven modules 1 include five isosceles right-angled triangle modules 101, one rectangular module 102, and one parallelogram module 103. The seven modules 1 are spliced ​​together to form a tangram structure. In this embodiment, the seven modules 1 are spliced ​​together to form a cube structure. When the modules 1 are spliced ​​together, the modules 1 are connected by magnetic adsorption.

[0030] When children are playing, the different combinations of Module 1 can create diverse play forms, enriching their play experience. At the same time, the playground equipment can be disassembled and combined according to actual needs. When it needs to be moved or transferred, each Module 1 can be disassembled and moved individually, reducing the difficulty of moving and transferring. The overall shape and placement of the equipment can be adjusted according to municipal construction plans, reducing dependence on fixed installation space and thus improving the applicability of the children's playground equipment.

[0031] Reference Figure 1 Each module 1 has a rounded edge design, which eliminates the sharp edges of the module 1 and reduces the risk of accidental injury to children when they play on the module 1 due to collision with the edge of the module 1, thus improving the safety of the device.

[0032] Reference Figure 1 and Figure 2 The module 1 has a storage slot 2, and a backrest component 3 is provided inside the storage slot 2. In this embodiment, the two storage slots 2 on the isosceles right triangle module 101 are used as an example for explanation. In this embodiment, the storage slot 2 is parallel to the length of the hypotenuse of the right triangle.

[0033] Reference Figure 1 and Figure 2 The backrest assembly 3 includes a back panel 31 and a sponge lumbar support 32 placed in the storage slot 2. When the backrest assembly 3 is in a stored state, the sponge lumbar support 32 and the back panel 31 together fill the storage slot 2, thus reducing the risk of children bumping or tripping due to the gaps in the storage slot 2 when they play on the surface of the module 1, and improving the safety of children when playing.

[0034] Reference Figure 1 and Figure 2The back panel 31 is rotatably connected inside the storage slot 2. The back panel 31 is provided with a concealed handle for easy gripping by the user. The module 1 has a support slot 4. When the back panel 31 is rotated 180° to a vertical position, the back panel 31 is inserted into the support slot 4. The sponge lumbar support 32 is detachably connected to the back panel 31 via Velcro. When the backrest assembly 3 is needed, first remove the sponge lumbar support 32 from the storage slot 2, then rotate the back panel 31 into the support slot 4, and finally attach the sponge lumbar support 32 to the backrest surface of the back panel 31. At this time, the back panel 31 unfolds and works together with the sponge lumbar support 32 to provide reliable support for children and improve comfort during play.

[0035] Reference Figure 3 and Figure 4 The bottom surface of module 1 is provided with a receiving groove 5. In this embodiment, the receiving groove 5 is provided as an example of an isosceles right triangle module 101. A connecting frame 6 is rotatably connected inside the receiving groove 5. The connecting frame 6 is in the shape of an inverted U. Universal wheels 61 are fixedly installed on both sides of the connecting frame 6 along the length direction.

[0036] Reference Figure 4 and Figure 5 A rotating shaft 7 is fixedly connected to the connecting frame 6. A rotating groove 8 is provided on the inner side wall of the receiving groove 5 to rotate with the rotating shaft 7. A rotation limiting component 9 is provided on the rotating shaft 7 to limit the rotation movement.

[0037] When moving module 1, the user rotates the connecting frame 6 to a vertical position and fixes it with the rotation limiting component 9. At this time, the caster wheel 61 is in contact with the ground. The user can easily push module 1 to move by using the rolling characteristics of the caster wheel 61. At the same time, the rotation limiting component 9 reduces the possibility that the caster wheel 61 may accidentally retract due to the rotation of the connecting frame 6, thus ensuring smooth movement. When module 1 does not need to be moved, the connecting frame 6 rotates to a horizontal position, causing the caster wheel 61 to leave the ground. Then, the horizontal position of the connecting frame 6 is fixed by the rotation limiting component 9. This allows the bottom surface of module 1 to be stably in contact with the ground, reducing the shaking caused by the caster wheel 61 contacting the ground, thereby reducing the risk of accidents caused by the shaking of the device during use by children.

[0038] Reference Figure 5 The rotation limiting component 9 includes a drive shaft 91 that is slidably sleeved on the outer surface of the rotating shaft 7. The end of the drive shaft 91 extends to the outer surface of the module 1 and is fixedly connected to a pull ring (not shown in the figure). The drive shaft 91 has a limiting groove 911 along the axial direction. In this embodiment, there are two limiting grooves 911, which are arranged on the radial sides of the drive shaft 91. A limiting block 71 is fixedly connected to the outer surface of the rotating shaft 7 and slidably connected in the limiting groove 911. The relative rotation between the rotating shaft 7 and the drive shaft 91 is limited by the sliding cooperation between the limiting groove 911 and the limiting block 71.

[0039] Reference Figure 5 A limiting block 92 is fixedly connected to the outer surface of the drive shaft 91. The limiting block 92 has a cubic structure. A square groove 81 is provided on the inner side wall of the rotating groove 8 near the receiving groove 5, which slides with the limiting block 71. The square groove 81 has the same cross section as the limiting block 92 to prevent the limiting block 92 from rotating. A circular groove 82 is provided on the inner side wall of the rotating groove 8 away from the receiving groove 5, which rotates with the limiting block 71. The circular groove 82 and the square groove 81 are interconnected.

[0040] Reference Figure 5 A retaining spring 93 is provided in the circular groove 82. One end of the retaining spring 93 is fixedly connected to the inner side wall of the circular groove 82 away from the receiving groove 5, and the other end is fixedly connected to the limiting block 71. The elastic force of the retaining spring 93 drives the limiting block 71 to be inserted into the square groove 81.

[0041] When the connecting frame 6 needs to be rotated, the user pulls the drive shaft 91 outward to compress the clamping spring 93. The drive shaft 91 drives the rotation limiting block 92 from the square groove 81 into the round groove 82. At this time, the rotation of the limiting block 71 and the drive shaft 91 is not restricted by the square groove 81. When the drive shaft 91 rotates, it drives the rotating shaft 7 to rotate through the limiting block 71 and the limiting groove 911, thereby realizing the rotation of the connecting frame 6. After the connecting frame 6 is rotated into place, the drive shaft 91 is released, and the elastic force of the clamping spring 93 drives the limiting block 71 to insert into the square groove 81. At this time, the square groove 81 restricts the rotation of the limiting block 71 and the drive shaft 91, thereby restricting the rotation of the rotating shaft 7 and fixing the position of the connecting frame 6.

[0042] The implementation principle of a child-friendly street smart playground device according to an embodiment of this application is as follows: When children are playing, the different combinations of modules 1 can form diverse play forms, enriching the children's play experience. At the same time, the playground device can be disassembled and combined according to actual needs. When it needs to be moved or transferred, each module 1 can be disassembled and moved separately, reducing the difficulty of moving and transferring. The overall shape and placement of the device can be adjusted according to the municipal construction plan, reducing the dependence on fixed installation space, thereby improving the applicability of the children's playground device.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
