Technical Field

[0001] This utility model relates to the field of car child seat technology, and in particular to a foldable child stroller seat. Background Technology

[0002] A car child safety seat is a seat designed specifically for children of different weights (or age groups) and installed in a car to effectively improve children's safety while traveling. Existing car child safety seats have limited seat rotation angles, making them difficult to adapt to different car frames and reducing their practicality. Therefore, we offer a foldable stroller seat. Utility Model Content

[0003] To address the problem that existing car child safety seats are difficult to adapt to different car frames, this invention provides a foldable child stroller seat.

[0004] This utility model is achieved using the following technical solution: a foldable children's stroller seat, including a seat plate, two sets of seat plate connecting flat irons symmetrically fixedly connected to the seat plate, a segmented plate on the outer side of the seat plate connecting flat irons, an armrest plate on the outer side of the segmented plate, an armrest pin on the armrest plate, an armrest pin spring on the armrest pin, a joint tooth on the outer side of the armrest plate, a joint tooth spring on the outer side of the joint tooth, a backrest joint on the outer side of the joint tooth, a seat on the outer side of the backrest joint, a seat cover on the seat, and an active button assembly on the seat.

[0005] As a further improvement to the above solution, the active button assembly includes a card holder button movably connected to the card holder, the card holder is provided with a locking pin, a locking pin spring is added between the locking pin and the card holder, the card holder is also provided with a memory pin, and a memory pin spring is added between the memory pin and the card holder.

[0006] As a further improvement to the above solution, a handrail seat is fixedly connected to the handrail iron plate, and a handrail is installed between the two sets of handrail seats.

[0007] As a further improvement to the above scheme, the number of the joint tooth springs is three sets, which are equidistantly distributed around the center of the joint tooth in a circumferential direction outside the joint tooth.

[0008] As a further improvement to the above solution, a groove is provided on the outside of the joint tooth corresponding to the position of the joint tooth spring.

[0009] As a further improvement to the above solution, the same backrest is installed on both sets of backrest joints, and a buckle is installed on the backrest.

[0010] As a further improvement to the above solution, a backrest segment locking pin is provided on the backrest joint, and a segment locking pin spring is added to the backrest segment locking pin.

[0011] As a further improvement to the above solution, the edge of the handrail metal sheet is provided with a slot.

[0012] As a further improvement to the above solution, the maximum angle by which the seat plate rotates around the card slot is 360°.

[0013] As a further improvement to the above solution, a leg rest is movably connected to the seat plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When the backrest approaches the seat plate, the seat plate will disengage, and the seat plate will be in a folded state. The entire seat can rotate 360° clockwise or counterclockwise around the seat, which makes it easy to adapt to various frames and improves the practicality of the device. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1:

[0023] Please combine Figure 1-3This embodiment of a foldable stroller seat includes a seat plate 1. Two sets of seat plate connecting flat irons 2 are symmetrically fixedly connected to the seat plate 1. A segmented plate 3 is provided on the outer side of the seat plate connecting flat irons 2. An armrest plate 4 is provided on the outer side of the segmented plate 3. An armrest latch 5 is provided on the armrest plate 4. An armrest latch spring 6 is added to the armrest latch 5. A joint tooth 7 is provided on the outer side of the armrest plate 4. A joint tooth spring 8 is provided on the outer side of the joint tooth 7. A backrest joint 9 is provided on the outer side of the backrest joint 9. A seat 10 is provided on the outer side of the backrest joint 9. A seat cover 11 is added to the seat 10. The seat 10 also has... The active button assembly includes an armrest seat 17 fixedly connected to the armrest iron plate 4, an armrest 18 installed between two sets of armrest seats 17, three sets of articulated tooth springs 8 equidistantly distributed around the center of the articulated tooth 7 on the outside of the articulated tooth 7, grooves corresponding to the positions of the articulated tooth springs 8 on the outside of the articulated tooth 7, the same backrest 19 installed on two sets of backrest joints 9, buckles 20 installed on the backrest 19, backrest segment locking pins 21 provided on the backrest joints 9, segment locking pin springs 22 added to the backrest segment locking pins 21, a locking groove provided on the edge of the armrest iron plate 4, and the maximum angle of rotation of the seat plate 1 around the locking seat 10 is 360°.

[0024] The active button assembly includes a card holder button 12 that is activally connected to the card holder 10. The card holder 10 is provided with a locking pin 13. A locking pin spring 14 is provided between the locking pin 13 and the card holder 10. The card holder 10 is also provided with a memory pin 15. A memory pin spring 16 is provided between the memory pin 15 and the card holder 10.

[0025] The implementation principle of a foldable child stroller seat in this application embodiment is as follows: When the backrest 19 is folded down to near the armrest 18 by the lever 20, the backrest joint 9 will disengage the armrest latch 5. When the backrest 19 approaches the seat 1, it will disengage the seat 1. At this time, the seat 1 will be in a folded state, and the entire seat can rotate 360° clockwise or counterclockwise around the seat 10, which facilitates its adaptation to various frames and improves the practicality of the device. When the backrest 19 is unfolded to a certain angle by the lever 20, the backrest segment latch 21 will be engaged in the slot on the armrest iron plate 4. As the backrest 19 continues to unfold, it can automatically drive the armrest 18 to open. When the backrest segment latch 21 is engaged in the first slot on the segment plate 3 of the seat, the armrest latch 5 will lock at the same time, thus completing the unfolding of the seat.

[0026] Example 2:

[0027] This embodiment is an improvement on embodiment 1, in that: a leg support 23 is movably connected to the seat plate 1, which can provide support for the legs.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
