Description

Technical Field

[0001] This application relates to the technical field of children's products, and in particular to a children's high chair. Background Technology

[0002] A high chair is a mealtime aid designed specifically for babies aged 6 months to 3 years. It uses a safety belt to secure the child's posture, helping them transition from being fed to independent eating. It not only cultivates independent eating habits but also allows for height adjustment to suit different age groups. To better cater to the consumption concepts and needs of young mothers, high chairs have been given more functions, such as integrating a swaddle, allowing for use from birth and providing greater convenience for parents during this special time.

[0003] However, in related technologies, swaddles are usually statically installed on children's high chairs, lacking the function of soothing infants and toddlers and failing to meet their usage needs. Summary of the Invention

[0004] Therefore, it is necessary to provide a children's high chair to address the problem that traditional technologies lack the function of soothing infants and young children and cannot meet their needs.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See Figures 1 to 3 This application illustrates a children's dining chair 100 according to one embodiment, which includes a chair frame 10, a drive device 20, and a swaddle 30. The chair frame 10 is a traditional dining chair with a complete structure and function, specifically including chair legs, a seat, and other components, which can be used by older infants and toddlers who are capable of sitting independently.

[0040] Furthermore, the chair frame 10 has an unfolded state and a folded state. When unfolded, it is convenient for infants and toddlers to use. When folded, it allows the children's dining chair 100 to have a smaller volume, which makes it easier to store and transport.

[0041] The drive device 20 is mounted on the chair frame 10; the swaddle 30 includes a swaddle base frame 31, which is rotatably connected to the chair frame 10 and connected to the drive device 20, and can swing relative to the chair frame 10 under the drive of the drive device 20.

[0042] In addition, the swaddle 30 also includes components such as a swaddle pad installed on the swaddle frame 31 for infants to sit, lie down, etc.

[0043] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the children's high chair 100 of this solution, the swaddle 30 can be directly rotated and installed on the chair frame 10 via the swaddle base 31, and can also be connected to the chair frame 10 via the drive device 20, so that the swaddle 30 can be stably installed on the chair frame 10, thereby safely and reliably supporting the infant placed in the swaddle 30. When in use, the infant is placed in the swaddle 30 and can drink milk or eat complementary food without the parents holding the infant; furthermore, when the infant plays or sleeps in the swaddle 30, the drive device 20 is activated, which in turn drives the swaddle 30 to rock relative to the chair frame 10, so that the infant gets a gentle rocking sensation, simulating the soothing effect produced by the mother holding and rocking, allowing the infant to use the children's high chair 100 more safely.

[0044] Please continue reading. Figure 1 and Figure 2 In one embodiment, the chair frame 10 has a first side and a second side located in its width direction, and the chair frame 10 includes a platform 11 arranged on the first side, a first support column 12 mounted on the platform 11, and a second support column 13 arranged on the second side.

[0045] One side of the swaddle frame 31 is rotatably connected to the first support column 12, and the other side of the swaddle frame 31 is rotatably connected to the second support column 13. The drive device 20 is mounted on the platform 11 and connected to one side of the swaddle frame 31.

[0046] For example, in this embodiment, the swaddle frame 31 is a rectangular ring-shaped rod structure, with the two sides of the swaddle frame 31 being opposite sides in its width direction. By simultaneously providing mounting support to both sides of the swaddle frame 31 in the width direction using the first support column 12 and the second support column 13, not only is the installation of the swaddle frame 31 more stable, but it also ensures that its up-and-down swaying in the vertical plane is smooth and safe. The platform 11 provides mounting and fixing for the drive device 20, so that the drive device 20 can smoothly output driving force to the swaddle frame 31 to drive the swaddle frame 31 to sway.

[0047] Please continue reading. Figures 3 to 7In one optional embodiment, the drive device 20 includes a power source 21, a transmission mechanism 22, and a swing assembly 23. The power source 21 is drivenly connected to the transmission mechanism 22, the transmission mechanism 22 is drivenly connected to one end of the swing assembly 23, and the other end of the swing assembly 23 is rotatably connected to the swaddle frame 31. During operation, the power source 21 outputs driving force to the swing assembly 23 via the transmission mechanism 22 to drive the swing assembly 23 to swing, which in turn drives the swaddle frame 31 to swing. The drive device 20 has a simple structure and working principle, and a short power transmission path, which helps to improve the responsiveness of the swinging motion of the swaddle frame 31.

[0048] Specifically, based on the above embodiments, the power source 21 includes a housing 211 and a drive motor 212. The housing 211 is disposed on the platform 11, and the drive motor 212 is installed in the housing 211.

[0049] The transmission mechanism 22 includes a transmission component and a linkage component. One end of the transmission component is connected to the motor shaft of the drive motor 212, the other end of the transmission component is connected to one end of the linkage component, and the other end of the linkage component is connected to the swing component 23.

[0050] The housing 211 houses the integrated drive motor 212 and transmission mechanism 22, making the drive unit 20 more compact and reducing space occupation, thus contributing to the miniaturization design of the children's high chair 100. The drive motor 212 outputs rotational driving force to the transmission assembly, which in turn transmits the rotational driving force to the linkage assembly, causing the linkage assembly to reciprocate, so that the linkage assembly can ultimately drive the swing assembly 23 and the swaddle frame 31 to swing.

[0051] In this application, the drive motor 212 is installed vertically in the housing 211 with its motor shaft facing downwards. This makes full use of the space between the swaddle frame 31 and the platform 11, while reducing the lateral space occupied, which is more conducive to the miniaturization design of the children's high chair 100.

[0052] Please continue reading. Figure 4 and Figure 5 In one embodiment, the transmission assembly includes a driving wheel 221, a transmission member 222, and a driven wheel 223. The driving wheel 221 is connected to the motor shaft of the drive motor 212, and the driven wheel 223 is connected to the linkage assembly. The transmission member 222 is fitted onto the outside of the driving wheel 221 and the driven wheel 223. With this configuration, the rotational driving force output by the drive motor 212 can be transmitted sequentially to the driven wheel 223 via the driving wheel 221 and the transmission member 222 during operation, thereby driving the linkage assembly to move through the driven wheel 223. The transmission structure is simple and the transmission path is short.

[0053] For example, the driving wheel 221, the transmission component 222, and the driven wheel 223 can be configured as any one of the following: a synchronous belt pulley mechanism, a synchronous sprocket mechanism, etc. The specific configuration can be flexibly selected according to actual needs.

[0054] However, it should be noted that in the above embodiment, the diameter of the driving wheel 221 is smaller than the diameter of the driven wheel 223. Therefore, during the transmission of rotational driving force from the driving wheel 221 to the driven wheel 223, the rotational speed will decrease, but the torque will increase at the same time. This ensures that there is sufficient driving torque to drive the swaddle 30 to rock, avoiding insufficient driving force that would affect the rocking effect and thus the user experience of the children's high chair 100.

[0055] Please continue reading. Figures 4 to 7 Furthermore, based on any of the above embodiments, the linkage assembly includes a worm gear 224, a worm wheel 225, and a linkage shaft 226. The worm gear 224 is coaxially connected to the driven wheel 223, the worm wheel 225 meshes with the worm gear 224, and the worm wheel 225 is mounted on the linkage shaft 226. The linkage shaft 226 is fixedly connected to the swing assembly 23. Power transmission is achieved through the meshing of the worm gear 224 and the worm wheel 225, resulting in stable, smooth, and precise power transmission. This also avoids slippage due to insufficient friction when the swaddle 30 is under excessive load, thus improving the reliability of the drive device 20.

[0056] Furthermore, in another embodiment, the swing assembly 23 includes an eccentric wheel 231 and a swing arm 232. One end of the eccentric wheel 231 is fixedly connected to the linkage shaft 226, and the other end of the eccentric wheel 231 is rotatably connected to one end of the swing arm 232. The other end of the swing arm 232 is rotatably connected to the swaddle frame 31.

[0057] Since the eccentric wheel 231 is eccentrically connected to the linkage shaft 226 and the two are fixedly installed, the linkage shaft 226 rotates around its own axis while driving the eccentric wheel 231 to revolve around the axis of the linkage shaft 226. This results in the eccentric wheel 231 providing a periodic pulling or pushing force to the swing arm 232 after each rotation. In this way, the swing arm 232 can also provide a periodic pushing and pulling drive to the swaddle frame 31, allowing the swaddle frame 31 to swing around the rotational connection point with the first support column 12 and the second support column 13 as the pivot point.

[0058] Of course, it should be noted that in other optional embodiments, other mature transmission methods in the prior art can also be used to realize the swaddling 30 rocking motion. The specific method can be flexibly selected according to actual needs, and will not be elaborated on here.

[0059] Furthermore, based on any of the above embodiments, the children's high chair 100 also includes a sensor 40 and a detection plate 50. The sensor 40 is mounted on the housing 211, and the detection plate 50 is connected to the worm gear 224. The sensor 40 and the detection plate 50 are fitted together. During operation, controlling the drive motor 212 to output a periodic alternating clockwise and counterclockwise rotational driving force is key to realizing the reciprocating rocking motion of the swaddle 30. Correspondingly, the worm gear 224 also rotates periodically clockwise or counterclockwise. By using the sensor 40 to detect the angle value of the detection plate 50 rotating in different directions, the rocking amplitude of the swaddle 30 can be controlled, avoiding the safety hazard of the infant falling due to excessive rocking amplitude.

[0060] For example, in an optional embodiment, the sensor 40 has a detection probe with a detection groove. The detection disk 50 includes a base and multiple grid posts, which are spaced apart circumferentially on the base. A slot is formed between adjacent grid posts, and any grid post and slot can rotate through the detection groove. Since the grid posts and slots are evenly distributed circumferentially and have a fixed width, their circumferential angles are also fixed. Based on this, the detection probe can control the rotation angle of the detection disk 50 by detecting the number of grid posts and / or slots that rotate through the detection groove, thereby controlling the swing amplitude of the swaddle 30. The implementation structure and working principle are simple, and the detection accuracy is high.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
