Description

Technical Field

[0001] This utility model relates to the field of children's stroller technology, and in particular to a children's stroller seat that is easy to fold. Background Technology

[0002] In the stroller industry, the design of easily foldable stroller seats directly impacts user convenience and safety. Currently, common stroller folding mechanisms on the market suffer from several problems: the folding process is complex and cumbersome, often requiring multiple steps; the folding structure is poorly designed, making it easy to pinch the user's hands during operation; and many existing mechanisms cannot be operated with one hand, requiring the user to use both hands, increasing the burden on the user. These shortcomings mainly stem from the fact that existing folding mechanisms typically employ separate locking mechanisms or non-linkage designs.

[0003] Therefore, it is necessary to provide a new, easily foldable stroller seat to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a foldable child stroller seat that makes the folding process of the seat and frame simpler, more convenient, and less labor-intensive.

[0005] To solve the above-mentioned technical problems, the present invention provides a foldable child stroller seat comprising: a backrest assembly, a seat assembly, an armrest assembly, and a seat socket. The lower end of the backrest assembly, the rear end of the seat assembly, the upper end of the seat socket, and the rear end of the armrest assembly are coaxially rotatably connected by rivets. The backrest assembly is provided with a backrest handle and a second safety mechanism. The seat assembly is provided with an armrest locking mechanism. The armrest locking mechanism and the seat lock are integrated into a single linkage structure, which achieves the linkage folding of the armrest assembly and the seat assembly through mechanical linkage and is connected to the frame unlocking mechanism.

[0006] Preferably, the integrated linkage structure includes a steel cable and a backrest locking tongue. The backrest handle is connected to the backrest locking tongue via the steel cable. The steel cable allows the movement of the backrest handle to be transmitted to the backrest locking tongue to release the lock between the backrest assembly and the seat assembly.

[0007] Preferably, it also includes a seat gear, and the backrest assembly is provided with a trapezoidal boss. The trapezoidal boss cooperates with the seat gear, so that the rotation of the backrest assembly drives the seat gear to move laterally, thereby releasing the locking of the armrest locking member.

[0008] Preferably, the linkage folding structure includes a locking release mechanism between the backrest assembly and the seat assembly, a lateral drive mechanism for the seat gear, and a compression engagement mechanism between the rear step of the seat assembly and the frame folding linkage top block. These mechanisms work together to achieve linkage folding.

[0009] Preferably, the seat plate assembly is provided with a handle hole for the user to apply force during operation.

[0010] Preferably, the integrated linkage structure includes a separable engagement mechanism between the seat gear and the seat socket, and a slider linkage assembly for the armrest locking component.

[0011] Compared with related technologies, the foldable child stroller seat provided by this utility model has the following advantages:

[0012] This utility model provides a foldable child stroller seat. Through an integrated linkage structure design, it not only simplifies the traditional multi-step folding operation into a continuous single-hand action, but also fundamentally improves operational safety through a mechanical linkage mechanism. The compression and engagement mechanism between the rear step of the seat assembly and the frame folding linkage top block allows for perfect synchronization between seat folding and frame folding, eliminating the jamming phenomenon common in traditional folding mechanisms and avoiding the risk of the operator's hand being pinched. While ensuring structural stability, it successfully transforms a complex technical solution into an intuitive user experience, making the folding operation of the child stroller simple, effortless, and safe, truly achieving the ideal effect of "one-touch folding," bringing significant technological progress to the field of children's travel products.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the foldable child stroller seat provided by this utility model; Figure 2 for Figure 1 This is a structural schematic diagram from another perspective; Figure 3 for Figure 1 The diagram shows a frontal sectional view of the structure. Figure 4 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 1 The diagram shows a side sectional view of the structure. Figure 6 for Figure 5 The enlarged schematic diagram of section B is shown. The foldable stroller seat includes: a backrest assembly 3, a seat assembly 1, an armrest assembly 2, and a seat socket 4. The lower end of the backrest assembly 3, the rear end of the seat assembly 1, the upper end of the seat socket 4, and the rear end of the armrest assembly 2 are coaxially rotatably connected by rivets. The backrest assembly 3 is equipped with a backrest handle 5 and a second safety device 6. The seat assembly 1 is equipped with an armrest locking mechanism. The armrest locking mechanism and the seat lock are integrated into a single linkage structure, which realizes the linkage folding of the armrest assembly 2 and the seat assembly 1 through mechanical linkage and is connected to the frame unlocking mechanism.

[0022] The integrated linkage structure includes a steel cable 9 and a backrest locking tongue 8. The backrest handle 5 is connected to the backrest locking tongue 8 via the steel cable 9. The steel cable 9 enables the movement of the backrest handle 5 to be transmitted to the backrest locking tongue 8 to release the lock between the backrest assembly 3 and the seat assembly 1.

[0023] It also includes a seat gear 7. The backrest assembly 3 is provided with a trapezoidal boss. The trapezoidal boss cooperates with the seat gear 7, so that the rotation of the backrest assembly 3 drives the seat gear 7 to move laterally, thereby releasing the locking of the armrest locking member.

[0024] The linkage folding structure includes a locking release mechanism between the backrest assembly 3 and the seat assembly 1, a lateral drive mechanism for the seat gear 7, and a compression engagement mechanism between the rear step of the seat assembly 1 and the frame folding linkage top block. These mechanisms work together to achieve linkage folding.

[0025] The seat plate assembly 1 is provided with a handle hole 10 for the user to apply force.

[0026] The integrated linkage structure includes a separable meshing mechanism between the seat gear 7 and the seat socket 4, and a slider linkage assembly for the armrest locking component.

[0027] The working principle of the foldable child stroller seat provided by this utility model is as follows:

[0028] In use, press the one-handed button on the frame inward, then slide the push handle assembly down to the lowest locking position, press the double safety 6 on the backrest assembly 3, and then pull the backrest handle 5 upward. This will cause the steel cable 9 to drive the backrest locking tongue 8, releasing the lock on the backrest and seat assembly 1. Then, continue to apply force to make the backrest assembly 3 rotate around the axis towards the front of the seat assembly 1. After rotating to a certain angle, the trapezoidal boss on the backrest assembly 3 will drive the seat gear 7 to move to the left, separating it from the seat socket 4 on the right. At the same time, because the seat gear 7 moves to the left, it unlocks the armrest locking piece, causing the armrest to rotate around the axis and fold onto the seat. At this time, the folded seat assembly rotates around the axis together and is compressed outward by the step at the rear end of the seat, thereby driving the various locking mechanisms on the frame. Then, under the action of gravity and inertia, it moves. Finally, by lifting the handle hole 10 of the seat assembly 1 with one hand, the purpose of folding the seat and frame with one hand is achieved.

[0029] Compared with related technologies, the foldable child stroller seat provided by this utility model has the following advantages:

[0030] This utility model provides a foldable child stroller seat. Through an integrated linkage structure design, it not only simplifies the traditional multi-step folding operation into a continuous single-hand action, but also fundamentally improves operational safety through a mechanical linkage mechanism. The compression and engagement mechanism between the rear step of the seat assembly 1 and the frame folding linkage top block allows for perfect synchronization between seat folding and frame folding, eliminating the jamming phenomenon common in traditional folding mechanisms and avoiding the risk of the operator's hand being pinched. While ensuring structural stability, it successfully transforms a complex technical solution into an intuitive user experience, making the folding operation of the child stroller simple, effortless, and safe, truly achieving the ideal effect of "one-touch folding," and bringing significant technological progress to the field of children's travel products.
