Description

Technical Field

[0001] This application relates to the field of seating technology, and in particular to a child chair and a chair for improving concentration training. Background Technology

[0002] Attention deficit hyperactivity disorder (ADHD) and learning difficulties are increasingly common among school-aged children. Their core symptoms—difficulty maintaining attention, hyperactivity, and impulsivity—severely affect children's classroom learning efficiency and academic performance. Current mainstream intervention programs include sensory integration training aimed at improving neurological function and sensory processing abilities, and computerized cognitive training focused on directly enhancing cognitive function.

[0003] During intervention training for children, chairs serve as essential infrastructure to support their learning, play, and rest. However, traditional chairs have significant limitations for active children, especially those with attention deficit hyperactivity disorder (ADHD).

[0004] For example, traditional chairs operate in a binary state of "either tipping over or remaining stable," failing to meet the neurophysiological needs of children, especially those with ADHD, who require moderate swaying to stimulate their vestibular and proprioceptive senses. Therefore, in terms of physical safety, traditional chairs lack stability and dynamic self-correction capabilities. Conventional four-legged chairs or chairs with fixed bases are prone to tipping over upon impact or pushing, potentially causing falls and injuries to children, posing a potential risk to the activity environment of children with ADHD. Utility Model Content

[0005] The purpose of this application is to propose a child chair and a chair for improving concentration training, which at least solves the problems of insufficient stability and dynamic self-centering ability of traditional chairs.

[0006] To achieve the above objectives, this application adopts the following technical solution: On one hand, this application provides a child seat, including: a counterweight base; a support body extending upward from the counterweight base; a seat cushion disposed on the upper end of the support body; and a balance ring, which is annular and disposed between the counterweight base and the seat cushion; the outline diameter of the counterweight base is smaller than the outline diameter of the seat cushion, and the outline diameter of the seat cushion is smaller than or equal to the outline diameter of the balance ring; the central axes of the counterweight base, the balance ring, and the seat cushion are coaxial, and the center of gravity of the child seat is located on the counterweight base and on the central axis of the counterweight base; when the outlines of the balance ring and the counterweight base are simultaneously supported on the same horizontal plane, the center of gravity of the child seat is located on the side of the counterweight base support point away from the balance ring.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the outer contours of both the counterweight base and the seat cushion are circular.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a plurality of support bars are provided between the balance ring and the counterweight base, and the plurality of support bars are evenly distributed around the balance ring; one end of the support bar is connected to the outside of the counterweight base, and the other end is connected to the balance ring, and the support bar is an arc shape with the opening direction facing the central axis of the balance ring.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom of the counterweight base is provided with a support plane, and the outer periphery of the counterweight base is an arc-shaped rounded corner structure surrounding the support plane.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a circular counterweight block is provided at the bottom of the counterweight base.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom of the counterweight base is provided with an elastic pad layer.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the support body is a lifting component whose height can be adjusted up and down.

[0013] On the other hand, based on the same technical concept of this application, this application also provides a chair for improving concentration training, including the child chair described above; the seat cushion includes a support base connected to the support body; multiple pressure sensors are arranged circumferentially on the upper part of the support base; a support plate is also provided on the upper part of the support base, and the support plate is supported by the multiple pressure sensors.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: a number of pressure sensors are distributed on the support plate.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: an elastic support pad is provided above the support plate.

[0016] To address the shortcomings of traditional seats in terms of stability and dynamic self-centering capability, this application offers the following advantages: This child seat consists of a counterweight base, a support body, a seat cushion, and a balance ring. The counterweight base diameter D1 < seat cushion diameter D2 ≤ balance ring diameter D3, and all three components are coaxial, with the center of gravity located on the counterweight base's central axis. When the balance ring and counterweight base are simultaneously supported on a horizontal surface, the center of gravity is located on the side of the counterweight base's support point furthest from the balance ring.

[0017] First, by concentrating the mass at the bottom through a counterweight base, a low center of gravity structure is created, enhancing the overall stability of the child seat. For example, even if a child twists or shifts their body significantly while sitting in the seat, the seat is not easily tilted or tipped over, demonstrating strong stability.

[0018] Secondly, by utilizing the characteristic that the center of gravity is located on the side of the counterweight base away from the balance ring when the balance ring and the counterweight base are simultaneously supported on the horizontal plane, a "self-resetting" torque is formed. When the seat is tilted, the gravitational torque causes the seat to automatically return to the upright position, giving this child seat a good dynamic self-correcting ability.

[0019] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0025] Traditional car seats operate in a binary state of "either tipping over or remaining stable," failing to meet the neurophysiological needs of children, especially those with ADHD, who require moderate swaying to stimulate their vestibular and proprioceptive senses. Therefore, in terms of physical safety, traditional car seats lack stability and dynamic self-correction capabilities. Conventional four-legged chairs or chairs with fixed bases are prone to tipping over upon impact or pushing, potentially causing falls and injuries to children, posing a potential risk to the activity environment of children with ADHD.

[0026] To address the issues of insufficient stability and dynamic self-centering capability in traditional seats, see [reference needed]. Figure 1-7 This application discloses a child chair and a chair for improving concentration training.

[0027] On the one hand, this application discloses a child seat that has a certain degree of stability and dynamic self-centering capability.

[0028] In the embodiments of this disclosure, such as Figure 1 and Figure 2As shown, this child seat includes a weight base 100, a support body 200, a seat cushion 300, and a balance ring 400. The weight base 100 concentrates most of the weight of the child seat, lowering the center of gravity C and placing it firmly on the seat. The support body 200 extends upwards from the weight base 100 to connect to and support the seat cushion 300. The seat cushion 300 primarily supports the child's body (buttocks) when seated, and is positioned above the support body 200. To enhance comfort, a soft, elastic support pad 500 can be installed on top of the seat cushion 300. The balance ring 400 is circular and positioned between the weight base 100 and the seat cushion 300. Furthermore, the outline diameter of the counterweight base 100 is smaller than the outline diameter of the seat cushion 300, and the outline diameter of the seat cushion 300 is smaller than or equal to the outline diameter of the balance ring 400; the central axes of the counterweight base 100, the balance ring 400, and the seat cushion 300 are coaxial along the height direction of the seat, and the center of gravity C of the child seat is located on the counterweight base 100 and on the central axis of the counterweight base 100; Figure 7 As shown, when the contours of the balance ring 400 and the counterweight base 100 are simultaneously supported on the same horizontal plane, the center of gravity C of the child seat is located on the side of the counterweight base 100 support point P (the point supported on the horizontal plane) away from the balance ring 400.

[0029] This child car seat consists of a weight base 100, a support body 200, a seat cushion 300, and a balance ring 400; Figure 6 As shown, the diameter D1 of the counterweight base 100 is less than the diameter D2 of the seat cushion 300 and less than the diameter D3 of the balance ring 400, preferably D3 is greater than D2, and the central axes of the three are coaxial, with the center of gravity C located on the central axis of the counterweight base 100. Since when the balance ring 400 and the counterweight base 100 are simultaneously supported on a horizontal plane, the center of gravity C is located on the side of the counterweight base 100 support point P away from the balance ring 400.

[0030] First, by concentrating the mass at the bottom through the counterweight base, a low center of gravity structure is formed, enhancing the overall stability of the child seat. For example, even if a child twists or shifts their body significantly while sitting in the seat, the child seat is not easily tilted or tipped over, demonstrating strong stability.

[0031] Secondly, the balance ring 400 can be positioned low to make it convenient for children to use as a footrest while riding.

[0032] Secondly, by utilizing the characteristic that when the balance ring 400 and the counterweight base 100 are simultaneously supported on the horizontal plane, the center of gravity C is located on the side of the counterweight base 100 support point away from the balance ring 400, a "self-resetting" torque is formed. When the seat is tilted, the gravitational torque causes the seat to automatically return to the upright position, giving this child seat a good dynamic return-to-center capability.

[0033] Specifically, firstly, we understand the ground in this scenario of using the child seat as a flat, level surface. When the child seat tipes over, such as... Figure 6 As shown, if the seat cushion 300 and the balance ring 400 are simultaneously supported on the ground, since the center of gravity C is located on the counterweight base 100, the child seat will tilt towards the counterweight base 100 to further ensure that the balance ring 400 and the counterweight base 100 are both supported on the ground. Figure 7 As shown, when the contours of the balance ring 400 and the counterweight base 100 are simultaneously supported on the same horizontal plane, the center of gravity C is located on the side of the counterweight base 100 support point away from the balance ring 400. Therefore, the child seat will swing around the support point P (contact point) where the counterweight base 100 is supported on the ground until the counterweight base 100 is placed stably on the ground, completing the adaptive dynamic return.

[0034] It is important to note that D3 should ideally be greater than D2. If D3 is less than D1, or even less than D2, the contours of the counterweight base 100 and the seat cushion 300 may be supported on the ground at the same time. In this case, the torque between the center of gravity C and the support point P may be too small, which is not conducive to the child seat returning to its original position after tilting.

[0035] In the embodiments of this disclosure, such as Figure 1-2 As shown, to ensure the stability and effectiveness of the dynamic self-centering capability of this child seat, the outer contours of the counterweight base 100, the balance ring 400, and the seat cushion 300 are all circular. Furthermore, several support strips 401 are provided between the balance ring 400 and the counterweight base 100, evenly distributed around the balance ring 400. One end of each support strip 401 connects to the outside of the counterweight base 100, and the other end connects to the balance ring 400. The support strip 401 is an arc shape with its opening facing the central axis of the balance ring 400. The support strips 401 serve two purposes: first, they provide a connection between the balance ring 400 and the counterweight base 100 to ensure structural stability and strength; second, they provide auxiliary support as the child seat swings from the balance ring 400 towards the counterweight base 100 on the ground, improving the smoothness of the posture transition during the dynamic return process of the child seat.

[0036] Furthermore, the bottom of the counterweight base 100 is provided with a support plane 101, and the outer periphery of the counterweight base 100 is an arc-shaped rounded corner structure 104 surrounding the support plane 101. Similarly, this improves the smoothness of posture transition during the dynamic reset of the child seat.

[0037] Furthermore, the bottom of the counterweight base 100 is provided with an elastic pad 102, such as a rubber layer or a urethane pad. This serves three purposes: First, it enhances the adhesion between the bottom of the counterweight base 100 and the ground, improving stability during use. Second, it reduces noise generated by friction between the bottom of the child seat and the ground when the child frequently twists and turns the seat. Third, it acts as a shock absorber; when the child seat tilts back and automatically returns to its original position, the elastic pad 102 at the bottom of the counterweight base 100 can absorb shocks in time, preventing the child seat from repeatedly swaying due to impact with the ground when the counterweight base 100 tilts back to upright, or reducing the number of swaying events, while also reducing noise from impacts with the ground.

[0038] In this embodiment, the support 200 is a height-adjustable lifting component, allowing the seat height of the seat cushion 300 to be adjusted according to the child's age, height, or sitting posture. Commonly used lifting components on seats include screw adjusters or gas spring assemblies.

[0039] In the embodiments of this disclosure, such as Figure 5 As shown, a circular counterweight 103, such as a metal plate of ordinary material, is provided at the bottom of the counterweight base 100 to increase the weight of the counterweight base 100, improve stability, and lower the center of gravity of the counterweight base 100. During manufacturing, the main body of the counterweight base 100, the support body 200, and the seat cushion 300 can all be made of high-strength plastic parts, and then the circular counterweight 103 is set at the bottom of the counterweight base 100 for counterweighting.

[0040] In summary, this child seat has good stability and dynamic return capability, meeting the general use needs of children with attention deficit hyperactivity disorder (ADHD).

[0041] On the other hand, considering that existing traditional children's chairs are inadequate in terms of posture monitoring and behavior analysis, or are out of touch with application scenarios such as cognitive training, they cannot distinguish the child's current or overall posture during training, nor can they capture subtle changes in posture and dynamic shifts in the center of gravity. This application discloses a chair for improving concentration training, which can be used to detect the child's current or overall posture during concentration training.

[0042] In the embodiments of this disclosure, such as Figure 3 and Figure 4 As shown, the chair used to improve concentration training includes the child chair described above; the seat cushion 300 includes a support base 301 connected to the support body 200; multiple pressure sensors 302 are distributed circumferentially around the central axis on the upper part of the support base 301; a support plate 303 is also provided on the upper part of the support base 301, and the support plate 303 is supported by multiple pressure sensors 302.

[0043] The support plate 303 can be made of rigid material, such as an aluminum alloy plate with a certain strength. To ensure that the support plate 303 has a relatively appropriate working state, an elastic support member is provided between the support plate 303 and the pressure sensor 302. Thus, when a body sits on the cushion 300 (support plate 303), the weight will press down on the elastic support member and then on the pressure sensor 302. The elastic support member on the side not under pressure compensates for the tendency of the support plate 303 to move away from the pressure sensor 302; naturally, the pressure on the pressure sensor 302 is less or not at all at this point.

[0044] The working principle is that when a child sits on the seat cushion 300 (support plate 303), the pressure changes of the support plate 303 on the pressure sensors 302 in different areas can be read. For example, even if the child appears to be sitting upright, their center of gravity may be tilted to the right, left, or constantly shifting from left to right relative to the seat. The state and frequency of these changes in the center of gravity can serve as a reference for the results of the child's attention training. However, the center of gravity may not be obvious to the naked eye, but the changes in the body's center of gravity will be captured by the pressure sensors 302. For example, a certain area can be simply designated as the left side of the seat, and another area as the right side. This left and right can be adaptively identified after the child has been sitting in the seat for a period of time. For example, the sides that change frequently are likely to be the child's left and right sides.

[0045] In this embodiment, a plurality of pressure sensors 304 are distributed on the support plate 303. The child's sitting posture can then be determined using these pressure sensors 304. For example, when sitting in a seat, the legs and buttocks apply pressure to some of the pressure sensors 304, forming pressure point distributions in a plane. Based on the distribution of these pressure points, a reference for the child's sitting position can be provided. The pressure sensor 304 can be understood as a push-button switch that triggers an immediate signal upon receiving a press, without requiring a precision sensor to detect pressure. It serves to delineate a pressure reference area by plotting pressure points within the support plate 303 region.

[0046] In this embodiment, an elastic support pad 500 is provided above the support plate 303. The function of the elastic support pad 500 is to provide a more comfortable seating experience when the seat is in use.

[0047] Specifically, the top of the support base 301 is open, thus creating an internal cavity. The opening of the support base 301 is circular, and an annular mounting plate is positioned near the opening within the cavity. Pressure sensors 302 are evenly distributed around the mounting plate, with their mounting portions mounted on the plate, the pressure-bearing portions facing upwards, and connected to the support plate 303. When the pressure-bearing portions are connected to the support plate 303, an elastic support element, such as a rubber pad, can be placed between them. The pressure sensors 304 can be push-button type repeaters without locking functionality, directly matrixed and distributed on the support plate 303. If push-button type repeaters are used, a pad 305 can be placed on the support plate 303. The pad 305 has honeycomb holes to avoid obstructing the installation position of the push-button type repeaters, thus mitigating the protrusion of the push-button type repeater mounting structure and eliminating the feeling of a protruding foreign object when riding.

[0048] Furthermore, an elastic support pad 500 is provided above the support plate 303. The support pad is configured such that it has a base ring 501, which is fixedly mounted on the opening of the support base 301, preferably in a detachable manner. A flexible membrane 502 is mounted on the base ring 501, and this flexible membrane 502 is in a taut state, covering the support plate 303. A flexible sheet 503 is then placed on top of the flexible membrane 502. The flexible sheet 503 is also connected to the base ring 501 or the flexible membrane 502 on all four sides, thus forming a cavity between the flexible membrane 502 and the flexible sheet 503. This cavity is filled with a filler 504 (such as elastic cotton, sponge, or fibrous material).

[0049] Furthermore, by connecting the chair intended for improving concentration training to an external data reading device or integrating a controller 600 (understood as a data analysis device) into the chair intended for improving concentration training, it is possible to achieve, but not limited to, detection and monitoring of children's sitting posture behavior during concentration training.

[0050] For example, in one usage method (not within the scope of this application), a controller 600, such as an ESP32 or STM32 microcontroller (preferably ESP32), is installed in the receiving cavity. A power supply device (external power supply or integrated rechargeable battery) is provided for the controller 600, and the controller 600 is connected to and reads the status and detection information of the pressure sensor 304 and pressure sensor 302. Firstly, a human-computer interaction device such as a display screen and a loudspeaker 700 can be integrated into the controller 600, and a dedicated application program can be set up for the controller 600 to record and analyze the child's sitting posture during training based on the status of the pressure sensor 304 and pressure sensor 302. Secondly, the controller 600 can be connected to and read the status and detection information of the pressure sensor 304 and pressure sensor 302, and then an external central control unit (such as a cloud platform or offline terminal) can be set up. The information read is then transmitted from the controller 600 to the central control unit for processing.

[0051] For example, if a child is set to kneel, sit cross-legged, or sit sideways, and if the system is set to remind the child, then the child can be reminded through a human-computer interaction device (such as a voice reminder).

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
