Description

Technical Field

[0001] The utility model relates to the technical field of seat cushions, in particular to a child seat cushion capable of automatically correcting sitting posture. Background Art

[0002] In recent years, from the perspective of different sitting posture correction products at home and abroad, although there are sitting posture correction products specifically for children in China, the emotional experience of the products is not enough, lacking innovation, and there is a lack of research on smart hardware products that can evaluate and correct sitting postures. Foreign smart correction products are mainly aimed at office workers. In summary, the methods of sitting posture detection in previous studies mainly include manual observation, video recording and analysis, and methods based on wearable sensors, while in terms of automatic adjustment of sitting posture, most of them are matching tables and chairs, which are not portable enough and are not yet mature for promotion and application.

[0003] Chinese patent CN201720331029.7 discloses a new type of airbag automatic inflatable health-preserving cushion, including a coat, a PVC / TPV inflatable sleeve, a memory foam, a magnetic layer and a bamboo charcoal layer, wherein a PVC / TPV inflatable sleeve is arranged inside the coat, and a left middle hole, a U-shaped hole, a right middle hole and a front hole are arranged on the PVC / TPV inflatable sleeve, and an automatic air valve port that cooperates with the PVC / TPV inflatable sleeve is arranged on the coat, and a memory foam is arranged between the coat and the PVC / TPV inflatable sleeve. The utility model adopts an ergonomic design, and the concave-convex structure can correct the sitting posture and prevent damage to the lumbar spine. The cushion is filled with natural high-temperature bamboo charcoal, which has good air permeability and sweat absorption; it is warm in winter and cool in summer. When the cushion is in use, the air in the airbag can flow quickly and unobstructed as the pressure point changes, which promotes smooth blood circulation, effectively alleviates diseases such as back pain caused by long-term sitting, and corrects the sitting posture; the product can be quickly squeezed into a small volume for easy carrying, and can be collected and stored as needed, and is convenient to carry.

[0004] Although the above technical solution provides an airbag seat cushion that can change its structure accordingly with the sitting posture, it is essentially a passive type of adjustment. The seat cushion structure only changes according to the sitting posture to adapt to various sitting postures, rather than correcting and adjusting the sitting posture of the occupant.

[0005] Therefore, it is necessary to provide a new cushion structure to solve the above-mentioned technical problems. Utility Model Content

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See also Figures 1 to 6 This embodiment discloses a child seat cushion that automatically corrects sitting posture, which can collect data in real time according to the sitting posture of the occupant, and actively perform targeted deformation to help the occupant correct the sitting posture.

[0032] The child seat cushion specifically comprises a base 1 and a cushion body 2, wherein the cushion body 2 is arranged on the top of the base 1. When in use, the base 1 serves as a bearing support structure, and the cushion body 2 serves as a contact structure for supporting the buttocks of the occupant.

[0033] Further, combined with Figure 2As shown, the base 1 is a shell structure with a "U"-shaped longitudinal section. In this embodiment, the base 1 is made of hard plastic. The cushion body 2 covers the top opening of the base 1 and is bonded to the top of the base 1 at the peripheral edge. The cushion body 2 is composed of an outer layer made of PVC material and an internal filling layer, and the internal filling layer is sponge. It should be noted that an opening and closing cover is provided on the base 1 to facilitate subsequent maintenance operations on the components inside the base 1.

[0034] The front of the base 1 is provided with a switch button 11, a charging port 12 and an indicator light 13. The charging port 12 is a type-c interface. The indicator light 13 is used to intuitively display whether the user's sitting posture is abnormal. When the red light is on, it means that the sitting posture is abnormal; when the green light is on, it means that the sitting posture is normal.

[0035] The top of the cushion body 2 is a seating end surface 21 , which is a horizontal end surface and has a chamfered structure at its peripheral corner. The elastic filler is evenly distributed below the seating end surface 21 .

[0036] like Figure 3 As shown, the cushion body 2 is provided with 6 detection points a at the corresponding sitting position, and the 6 detection points a are evenly and symmetrically distributed in the front-back and left-right directions on the transverse end surface of the cushion body 2. Specifically, in this embodiment, the 6 detection points a are divided into two left and right groups arranged at intervals, and three front and back groups, forming an inverted bracket shape as a whole. This structure is conducive to the differentiated control of the front-back and left-right of the sitting posture, so as to obtain the relevant left-right or front-back deviation trend.

[0037] Combination Figure 2 , a one-to-one corresponding sensor 7 is provided directly below the detection point a, and the sensor 7 can detect the compressive strength of the monitoring point area directly above it, and a one-to-one corresponding buffer device 5 is provided at the bottom of the sensor 7, and a one-to-one corresponding adjustment device 3 is provided at the bottom of the buffer device 5. The sensor 7, the buffer device 5 and the adjustment device 3 located below the same monitoring point constitute a response module, and the adjustment device 3 located in the same response module can control the structure at the top to move longitudinally. When in use, the passenger's buttocks press down on the cushion body 2, and the sponge is first used as a filler for appropriate buffering, and the continuous downward pressure is applied to the sensor 7 below, and the sensor 7 detects the strength of the force. The difference in the detection results of the sensors 7 at different positions can be calculated through the corresponding algorithm to obtain whether there is a deviation in the sitting posture and whether it is in the correct sitting posture state.

[0038] In this embodiment, the sensor 7 adopts a resistive flexible array pressure sensor 7, which is composed of two pieces of metal materials bonded to each other. It uses the characteristics of changes in contact surface and resistivity when the two pieces of material are subjected to force to convert the force change into a change in resistance value. This is a prior art, and the specific structure and the working principle on which the structure is based during operation will not be repeated here.

[0039] The buffer device 5 includes a damper 51 and a spring 52 which are vertically arranged and interconnected, and its function is to play a buffering role and improve riding comfort.

[0040] Furthermore, the transmission end of the regulating device 3 is arranged upward, and the transmission end is connected to the first plate body 4. The sensor 7 and the buffer device 5 located in the same response module are arranged above the first plate body 4. Each area directly above the first plate body 4 corresponds to the monitoring point above it one by one, and a plurality of response areas b distributed at intervals are formed at the bottom of the cushion body 2, such as Figure 5 As shown. In actual use, each adjustment device can independently control the first plate body 4 on its top to perform lifting activities, and complete the independent lifting and lowering activity control of the response area b, which is conducive to accurate and targeted adjustment of the pressure applied to the detection point a in each area according to the sitting posture (for example, when the detection result of the detection point a at a certain position is large, the adjustment device 3 corresponding to the position lifts the first plate body 4 on its top, and the spring 52 on its top will be further compressed after lifting, and then after balancing with the downward pressure from above, the continued lifting of the first plate body 4 will lift the limb area at the top of the position, thereby achieving the effect of automatic correction of the sitting posture).

[0041] In other embodiments, a position adjustment structure is provided between the bottom of the adjustment device 3 and the base 1, specifically a strip hole and a bolt structure, which can adjust the position of the adjustment device, thereby adjusting the detection point according to needs. In addition, a longitudinal guide structure can be provided between each component of the response module and the base 1 to make its lifting activity more stable and reliable.

[0042] Further, combined with Figure 2 and Figure 6 , a second plate 6 is provided between the sensor 7 and the buffer device 5, two left and right separate second plates 6 are provided at the bottom of the cushion body 2, and the sensors 7 in the response module located on the left and right sides of the cushion body 2 are divided into two groups, and three sensors in each group are arranged on a second plate 6 to form two linkage areas c. This structure enables the left and right sides to form a linkage structure in the front-to-back direction, and the linkage structure can produce mutual influence when under pressure. It should be noted that due to the limited support point area provided by the spring 52 at the bottom of the second plate 6, under the condition of uneven front and rear forces, the second plate 6 will undergo corresponding tilt and swing changes, which will not affect the detection work of the front and rear sensors 7, and the linkage area c can also perform appropriate correlation effects when the control device drives the deformation, so as to avoid the local deformation being too abrupt and affecting the riding experience.

[0043] A control system is provided inside the base 1, and the control system includes a power module, a communication module, a processing module, etc., which are used to connect and control various electronic components. It is a prior art, and the specific structure and the working principle based on the structure during operation will not be repeated here.

[0044] Combination Figure 4 As shown, the entire seat cushion is used as a hardware system. The control system is used to communicate and connect with fixed terminals (such as computers, control cabinets, etc.) or mobile terminals (such as mobile phones, tablets, etc.), and transmit data. Then, the control system is used to communicate and connect with the cloud platform, and transmit data to form a complete processing system. The specific process is to collect sitting pressure signals and classify sitting postures through hardware terminals, and then send the results to the cloud server. The Android / PC client can intuitively view the pressure distribution diagram and the duration of bad sitting postures, and automatically adjust the pressure to allow users to adjust to a normal sitting posture.

[0045] During the specific implementation of this embodiment, the pressure values ​​of various parts of the cushion body 2 are measured by the sensor 7, and the pressure values ​​of the front and the back, and the left and the right are compared, and fluctuations are allowed within a certain range. Focus on observing the pressure values ​​measured by the 6 pressure sensors 7 distributed in different positions on the cushion, collect data, and evaluate whether the sitting posture is normal. When the green light is on, it means that the sitting posture is normal; when the red light is on, it means that the sitting posture is abnormal. When the sensor 7 is subjected to uneven pressure distribution to a certain value, the control system sends a corresponding instruction, starts the adjustment device 3, and moves the structure of the response module at the target position longitudinally, so that the pressure of the front and the back, the left and the right is within the normal range, and the pressure distribution is uniform, thereby automatically adjusting the child's sitting posture (actually, if the detection value of the detection point a on the left rear side is larger, the structure of the response module on the left rear side is lifted, or the structure of the remaining areas is sunk synchronously).

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
