Description

Technical Field

[0001] The invention relates to the field of children's appliances, in particular to a child seat. Background Art

[0002] Most of the existing child seats are foldable and can be quickly detached from the frame. Common child seats include a cushion assembly, a backrest assembly, a front armrest assembly, and mounting assemblies on both sides that can be plugged and connected to the baby carriage frame. A backrest adjustment mechanism is provided between the backrest assembly and the mounting assembly to achieve locking and positioning of the backrest assembly at different angles. The existing child seat is generally folded by a four-bar linkage consisting of four components. The four-bar linkage is locked when unfolded and unlocked when folded. However, the four-bar linkage of the existing child seat generally includes a backrest assembly and a cushion assembly, and has the following disadvantages when used: when the backrest assembly is flipped forward and unlocked, the cushion assembly tends to flip down and forward. At this time, if the child sitting in the four-bar linkage has not completely left the seat, it is easy to fall from the cushion assembly, so there are certain safety hazards when used. Summary of the invention

[0039] like Figures 1 to 10As shown, a child seat pocket comprises a cushion assembly 1, a backrest assembly 2, a front armrest assembly 3, a mounting assembly 4 connected to the baby carriage frame, and a connecting rod 5; wherein, the mounting assembly 4 and the connecting rod 5 are two each and are arranged symmetrically on both sides of the cushion assembly 1, the backrest assembly 2, and the front armrest assembly 3; the mounting assembly 4 is coaxially rotatably connected to the corresponding rear part of the front armrest assembly 3 and the lower part of the backrest assembly 2 from the outside to the inside, and the lower end of the mounting assembly 4 is rotatably connected to the corresponding rear part of the cushion assembly 1; the connecting rod 5 is located in front of the mounting assembly 4, the upper end of the connecting rod 5 is rotatably connected to the corresponding front armrest assembly 3, and the lower end of the connecting rod 5 is rotatably connected to the corresponding cushion assembly 1. wherein, the connecting rod 5, the cushion assembly 1, the mounting assembly 4, and the front armrest assembly 3 constitute a four-link mechanism.

[0040] When the child seat pocket is in the unfolded state, the rotation point of the connecting rod 5 and the front armrest assembly 3 is located in front of the rotation point of the front armrest assembly 3 and the mounting assembly 4, the rotation point of the connecting rod 5 and the seat cushion assembly 1 is located in front of the rotation point of the seat cushion assembly 1 and the mounting assembly 4, and the rotation point of the front armrest assembly 3 and the mounting assembly 4 is located above the rotation point of the seat cushion assembly 1 and the mounting assembly 4.

[0041] In this embodiment, a backrest adjustment mechanism is provided between the backrest assembly 2 and the front armrest assembly 3 to achieve locking and positioning of the backrest assembly 2 at different use angles. Since the backrest adjustment mechanism is a common mechanism in the art, this embodiment is only different from the prior art in terms of the setting position, so no further description or specific structural limitation is made here.

[0042] In this embodiment, a folding locking mechanism 6 is provided between the front armrest assembly 3 and the mounting assembly 4, which can be unlocked by flipping the backrest assembly 2 forward to reduce the angle between the backrest assembly 2 and the seat cushion assembly 1. Since the connecting rod 5, the seat cushion assembly 1, the mounting assembly 4 and the front armrest assembly 3 form a four-link mechanism, the positioning of the four-link mechanism can be achieved by locking any one of the rotation points, and in this embodiment, the front armrest assembly 3 and the mounting assembly 4 are locked by the folding locking mechanism 6 to achieve the deployment locking of the four-link mechanism.

[0043] like Figures 3 to 6As shown, in this embodiment, the specific structure of the folding locking mechanism 6 is: the folding locking mechanism 6 includes a gear 6-1 that can slide left and right and a return spring 6-2, the mounting assembly 4 has a first tooth groove 6-4 corresponding to the gear 6-1, the front armrest assembly 3 has a second tooth groove 6-3 corresponding to the gear 6-1, and the return spring 6-2 is arranged between the gear 6-1 and the first tooth groove 6-4; the folding locking mechanism 6 is locked or not by whether the gear 6-1 is simultaneously stuck in the first tooth groove 6-4 and the second tooth groove 6-3.

[0044] like Figures 3 to 7 As shown, the specific implementation method of releasing the lock of the folding locking mechanism 6 by flipping the backrest assembly 2 forward to reduce the angle between it and the cushion assembly 1 is as follows: the gear 6-1 has a boss 6-1-1, the front armrest assembly 3 has a slot 3-1 for the boss 6-1-1 to pass through and slide left and right, and the backrest assembly 2 has a guide groove 2-1 for the boss 6-1-1 to be inserted into and slide circumferentially; the side end of the guide groove 2-1 has a guide slope 2-1-1 for guiding the boss 6-1-1 to slide out of the guide groove 2-1.

[0045] There are preferably two protrusions 6-1-1, which are arranged on both sides of the end surface of the gear 6-1 close to the backrest assembly 2; the slots 3-1 and the guide grooves 2-1 are two corresponding to the two protrusions 6-1-1. This design can improve the stability during the unlocking operation and ensure that the gear 6-1 can move outward smoothly.

[0046] The boss 6-1-1 has a matching inclined surface 6-1-2 corresponding to the guiding inclined surface 2-1-1 of the guiding groove 2-1. This design allows the boss 6-1-1 to smoothly slide out of or into the corresponding guiding groove 2-1 when the backrest assembly 2 rotates.

[0047] In this embodiment, the mounting assembly 4 is preferably a plug-in socket that is plugged into the mounting sockets on both sides of the baby stroller frame, and the plug-in socket is provided with a plug-in locking mechanism for locking the above-mentioned mounting socket. Since the plug-in locking mechanism is a common mechanism in the field, it is not described here and the specific structure is not limited. This design can facilitate the installation and removal between the child seat pocket and the baby stroller frame.

[0048] The working principle of the present invention is:

[0049] like Figure 1 , Figure 2 as well as Figure 8 As shown, when the folding locking mechanism 6 is in the locked state, the gear 6-1 is simultaneously stuck in the first tooth groove 6-4 and the second tooth groove 6-3, at which time the front armrest assembly 3 and the mounting assembly 4 are relatively fixed, and the four-link mechanism is in the locked state;

[0050] like Figure 8 As shown in the A, B, and C positions in the figure, when the backrest assembly 2 is adjusted at different use angles, the boss 6-1-1 of the gear 6-1 slides in the guide groove 2-1 of the backrest assembly 2; at this time, the folding locking mechanism 6 and the four-link mechanism are still in a locked state;

[0051] like Figure 8 The D position in Fig. 9 As shown, when the backrest assembly 2 flips forward and the boss 6-1-1 slides out of the guide groove 2-1, the backrest assembly 2 pushes the gear 6-1 outward through the boss 6-1-1. When the gear 6-1 completely enters the first tooth groove 6-4 and disengages from the second tooth groove 6-2, the folding locking mechanism 6 enters the unlocked state. At this time, the front armrest assembly 3 and the mounting assembly 4 can rotate relative to each other, and the four-link mechanism is in a free state.

[0052] At this time, the backrest assembly 2 continues to flip forward (if the child sitting on it has not left the seat, it cannot be rotated forward), and the backrest assembly 2 drives the front armrest assembly 3, the connecting rod 5 and the seat cushion assembly 1 to rotate forward and downward and fold, thereby completing the folding and folding of the four-link mechanism. Fig.10 shown.

[0053] The connecting rod 5, the seat cushion assembly 1, the mounting assembly 4 and the front armrest assembly 3 of the present invention form a four-link mechanism, and the front armrest assembly 3 and the mounting assembly 4 are locked by the folding locking mechanism 6 to achieve the unfolding and locking of the four-link mechanism. The backrest assembly 2 is independent of the four-link mechanism, so when the backrest assembly 2 is unlocked by flipping forward, the seat cushion assembly 1 will not immediately flip forward and downward, thereby preventing the child from falling off the seat cushion assembly 1 before completely leaving the seat, thereby improving the safety performance during use.

[0054] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.
