Description

Technical Field

[0001] This utility model relates to a baby seat and a stroller. Background Technology

[0002] A stroller typically consists of a stroller frame and a child seat. Seat sockets are installed on both sides of the stroller frame's push rod, while seat plugs are installed on both sides of the child seat. The child seat is connected to the stroller frame via the seat plugs and seat sockets, and then locked using a locking mechanism. To unlock, one usually grasps both sides of the child seat's push rod simultaneously, presses the unlock button to release the lock, and then lifts the child seat from the stroller frame.

[0003] In existing technologies, locking mechanisms do not have an unlocking and pausing function. To facilitate unlocking, the seat socket is usually extended upwards by a certain distance from the push rod frame, or the seat plug is extended downwards by a certain distance from the seat frame. This provides sufficient gripping space for both hands and unlocking space when removing the child seat. For example, in a child stroller with patent publication number CN105599800A, and in a child stroller with patent publication number CN205022656U that can be converted between single and double strollers, the combination of the seat plug and seat socket makes the child seat protrude upwards relative to the stroller frame, affecting the shape.

[0004] Therefore, this utility model provides a child seat that can be locked in the unlocked position by pressing the buttons on the two side seat plugs. When removing the child seat from the stroller frame, one hand lifts the front seat bar or front armrest of the seat and the other hand lifts the backrest frame of the seat, which is of practical value.

Detailed Implementation

[0029] The toddler seat includes a foldable seat frame and seat plugs 1 located on both sides for connecting to seat sockets 4 on both sides of a children's product. The children's product can be a high chair, a swing, a stroller, etc. The toddler seat is attached to the children's product via the seat plugs 1 and can be removed when no longer needed.

[0030] In this embodiment, a stroller is used as an example, such as Figure 1 , Figure 2 , Figure 9 As shown, the stroller includes a stroller frame and a child seat. The child seat is connected to the two push rods on both sides of the stroller frame via a seat plug and a seat socket. The left and right sides of the stroller frame each have a push rod, and the inner sides of each push rod are fitted with a seat socket 4. Each seat socket 4 has an upward-facing side-opening slot. The side-opening slot has a locking hole 41 on its inner wall in the left-right direction and a recess 42 in the front-back direction.

[0031] like Figure 3-8 As shown, each side of the seat plug 1 is circular, and there is a plug-in body 11 on the outer circular end face of the seat plug 1. The seat plug 1 is provided with a locking mechanism 2 that locks onto the corresponding seat socket 4.

[0032] The locking mechanism 2 includes a latch 21 that slides in the seat plug 1 along the left and right direction, a latch elastic element 22 that allows the latch 21 to pop out between the latch 21 and the seat plug 1, and a button 23 that slides up and down on the top of the seat plug 1. Both the button 23 and the latch 21 are provided with guide ramps 24. Pressing the button 23 downwards controls the latch 21 to retract into the seat plug 1.

[0033] The seat plug 1 is also equipped with an unlocking and retaining structure 3 that engages with the retracted latch 21 to maintain its retracted state. The unlocking and retaining structure 3 includes retaining members 31 symmetrically arranged on both sides of the latch 21. Each retaining member 31 is pivotally connected to the seat plug 1 around a first axis 32 at its center. The upper end of the retaining member 31 is a locking head 31a, and the lower end is a release contact 31b. The locking head 31a is a ratchet with a bevel, and the left and right sides of the latch 21 are also equipped with ratchet teeth. The axis of the first axis 32 on the corresponding sides extends along the left and right direction of the child seat, and the sliding direction of the latch 21 is parallel to it. A retaining elastic member 33 is provided between the locking head 31a and the seat plug 1 to move the locking head 31a toward the latch 21.

[0034] The locking mechanism 2 has a locked position and an unlocked position. In the locked position, the locking tongue 21 pops out of the housing of the seat plug 1 in the left and right direction, and the two release contacts 31b pop out of the housing of the seat plug 1 in the front and back directions respectively.

[0035] Press button 23. Under the action of guide ramp 24, the locking tongue elastic element 22 is overcome, and the locking tongue 21 is driven to retract into the seat plug 1 in the left and right direction. During the retraction process, the locking head 31a is driven to rotate around the first axis through the ratchet ramp to avoid retraction. When the locking tongue 21 is retracted into place, the locking head 31a is elastically reset and moves to the front side of the ratchet on the side of the locking tongue 21, blocking the path of the locking tongue 21 to pop out again. The locking head 31a is engaged with the side of the locking tongue 21.

[0036] In the unlocked position, the latch 21 overcomes the latch elastic element 22 and retracts into the housing of the seat plug 1, while the two release contacts 31b eject from the housing of the seat plug 1 in the front and rear directions respectively.

[0037] The side opening slot of the seat socket has a lock hole 41 on the inner wall in the left and right directions that cooperates with the lock tongue 21, and a recess 42 on the front and rear side walls that cooperates with the release contact 31b.

[0038] When the baby seat is installed on the stroller frame, the seat plug 1 is inserted into the corresponding side slot of the seat socket 4. Under the action of the front and rear side walls of the seat socket 4, the release contact 31b is pressed and retracted into the seat plug 1. The latch 31a retracts and disengages from the side of the locking tongue 21. When the locking tongue 21 springs into the lock hole 41, the release contact 31b is inserted into the recess 42 and the position is locked.

[0039] Press the buttons 23 on both sides to put the locking mechanism 2 in the unlocked position. The user can lift the front seat bar or front armrest of the seat with one hand and the backrest of the seat with the other hand to lift the child seat from the stroller frame. During the lifting process, the release contact 31b is pressed and retracted into the seat plug 1 by the action of the front and rear side walls of the seat socket 4, releasing the locking tongue 21. The locking tongue 21 is first popped out and reset by the action of the locking tongue elastic element 22. After the seat plug 1 is completely separated from the seat socket, the two release contacts 31b pop out and reset the housing of the seat plug 1 in the front and rear directions respectively.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
