[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] First, for ease of description, the term "end" in the text refers to the endpoint of the structure, or a point or region in that lateral direction, or a specific structure connected to that point or region.

[0041] See Figures 1-3This application provides a child chair 1000, including two oppositely arranged side supports 100. Each side support 100 includes a first leg 110 and a second leg 120 pivotally connected about a rotation axis. The direction in which the two side supports 100 are located is the width direction. Figure 1 and Figure 2 The view along the width direction (i.e., the side view below) is shown, and the side support 100 has... Figure 1 The unfolded state shown and Figure 2 The folded state shown.

[0042] The child chair in this embodiment also includes a support member 200 and a transmission member. The support member 200 is disposed between two side supports 100 and is rotatably connected to the first foot rod 110. The support member 200 can rotate around a horizontal axis and has a relative use state and a storage state. In the use state, the support member 200 can support the body parts of the occupant. In the storage state, the support member 200 rotates to reduce the volume of the child chair for easy storage.

[0043] The transmission component 300 is disposed between the second leg 120 and the support component 200. The transmission component 300 is connected or linked to the second leg 120 and the support component 200, or is partially part of one of them. When folded, the second leg 120 rotates towards the first leg 110, and the transmission component 300 drives the support component 200 to rotate to switch the storage state. When unfolded, the second leg 120 rotates away from the first leg 110, and the transmission component 300 drives the support component 200 to rotate to switch the use state.

[0044] When the child chair in this embodiment is folded or unfolded, the second leg 120 drives the support member to rotate synchronously to the storage state or the use state through the transmission component. Compared with the prior art, this saves the operation of rotating the seat plate and foot pedal, making the operation more convenient.

[0045] The support member 200 lies flat in use, partially extending beyond the space defined by the side supports 100. In the storage state, it is arranged at an angle relative to its use state. (See attached diagram.) Figure 1 The two side supports 100 define a space. In the storage state, the support member 200 is hidden in the space defined by the two side supports 100. Specifically, it can be completely hidden in the space, or more than half of the support member 200 can be hidden in the space, so as to reduce the size of the children's chair in the storage state, making it easier to store and with a simpler appearance.

[0046] In one embodiment, the transmission member 300 is linked to the support member 200 and the second foot rod 120, and the transmission member 300 is slidably mounted on the first foot rod 110 and movably connected to the support member 200. The transmission member 300 is driven by the top end of the second foot rod 120. (See reference...) Figure 1 and Figure 2The second foot lever 120 has a gear ring 121 arranged around the rotation axis at its top end. The transmission component 300 has a rack 310 that meshes with the gear ring 121. The support component 200 and the transmission component 300 rotate and slide relative to each other. For example, the transmission component 300 and the support component 200 are connected by a linkage pin 320, one of which is provided with a waist-shaped hole 210 for the linkage pin 320 to move. Figure 3 A waist-shaped hole 210 is formed on the support member 200, and the linkage pin 320 can slide and rotate within the waist-shaped hole 210.

[0047] Depend on Figures 1 to 2 When folded, the gear ring 121 drives the transmission component 300 to slide (shown as upward sliding in the diagram), and the transmission component 300 drives the support component 200 to rotate around the corresponding horizontal axis to the storage state; Figures 2 to 1 When unfolded, the gear ring 121 drives the transmission component 300 to slide (shown as sliding down in the diagram), and the transmission component 300 drives the support component 200 to rotate around the corresponding horizontal axis to the working state. The rotation direction of the support component 200 is not limited to the above-mentioned rotation direction, but can also be the opposite.

[0048] In one embodiment, the gear ring 121 may be part of the second foot 120, or a gear with the gear ring 121, which is coaxial with the axis of rotation.

[0049] In one embodiment, from a side view, the transmission member 300 is hidden or obscured by the first foot 110. For example, the inner side of the first foot 110 has a groove, and the transmission member 300 is slidably mounted in the groove. The first foot 110 includes a body 111 and a lug 112. The second foot 120 is hinged to the lug 112. The groove extends along the extension direction of the body 111, resulting in a simple appearance while providing sufficient sliding stroke for the transmission member 300.

[0050] In one embodiment, the transmission member 300 and the second leg 120 are eccentrically rotatably connected (with the rotation axis as the center). When folded or unfolded, the second leg 120 rotates and drives the transmission member 300 to move, thereby driving the support member 200 to rotate to the corresponding state. The transmission member 300 is also rotatably connected to the support member 200. For example, the transmission member 300 is a rod with its two ends rotatably connected to the second leg 120 and the support member 200, respectively.

[0051] In one embodiment, there are multiple support members 200, and different support members 200 are located at different heights on the side support 100, such as a seat cushion at a higher position and a footrest at a lower position. All support members 200 are linked to the aforementioned transmission member 300. When folding or unfolding, the transmission member 300 drives all support members 200 to rotate synchronously and switch to the corresponding state, further facilitating operation. Synchronous rotation among the support members is understood as starting and ending movement at the same time, with the movement trajectories of each support member, such as rotation angle and rotation speed, being the same or different.

[0052] The structure of the aforementioned transmission component allows the support member 200 to be connected only to the first foot bar 110, without needing to extend and connect to the second foot bar 120. For example, the length of the support member 200 can be shortened, such as the rear end of the foot pedal not exceeding the first foot bar 110.

[0053] In one embodiment, the support member 200 is detachably connected to the first leg 110. In another embodiment, the height of the support member 200 relative to the first leg 110 is adjustable.

[0054] In some embodiments, the first leg 110 and the second leg 120 are coplanar; or the first leg 110 and the second leg 120 are offset from each other. The first leg 110 and the second leg 120 are tilted in different directions relative to the plumb line in the unfolded state, and the transmission member 300 is arranged along the tilting direction of the first leg 110. Preferably, during folding and unfolding, the transmission member 300 is always within the space defined by the two first leg 110s.

[0055] In one embodiment, a transverse connecting rod is provided between the two second leg rods 120 to keep the two second leg rods 120 moving synchronously.

[0056] In some embodiments, the child chair is provided with a first locking structure that keeps the support member in a usable state, and a first unlocking member that correspondingly unlocks the first locking mechanism. The child chair is also provided with a second locking mechanism that keeps the side support in an extended state, and a second unlocking member that correspondingly unlocks the second locking mechanism. The first and second unlocking members are independent of each other or linked together, or the first unlocking member also serves as the second unlocking member.

[0057] When the child chair of this application is folded or unfolded, the support component is driven to rotate synchronously to the storage state or the use state through the transmission component, which saves the operation of rotating the seat plate and foot pedal compared with the prior art, making the operation more convenient.

[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0059] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, 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 modifications and improvements all fall within the protection scope of this application.
