detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments of the present invention.

Referring to the seat of the children's stroller shown in Figures 1 to 3, it includes a seat frame that can be converted into a seat state or a sleeping basket state, a seat cover (not shown) on the seat frame, and a Locking mechanism for locking the seat frame. The seat frame includes a surrounding frame 1, and the surrounding frame 1 includes an upper surrounding frame 11 and a lower surrounding frame 12, and the upper surrounding frame 11 and the lower surrounding frame 12 form a circular closed surrounding frame 1. The middle part of the surrounding frame 1 is fixedly connected with a surrounding frame support 2, which is located behind the surrounding frame 1. The surrounding frame support 2 has a rotating shaft 21 whose axis line extends along the left and right directions of the seat frame. Here, the definition of the direction Both are defined according to the direction of the child sitting on the seat, where the left and right directions are the left and right directions in Figure 1, and the front and rear directions are the line of sight of the observer when observing Figure 1, and the end far away from the observer After that, the up-down direction refers to the up-down direction in FIG. 1 .

Referring to Figures 1 to 3, the seat frame also includes a back panel 3, a seat panel 4, an upper footrest 5 and a lower footrest 6 arranged sequentially from top to bottom, the lower end of the back panel 3, the rear of the seat panel 4 The ends are all rotatably arranged on the rotating shaft 21, the front end of the seat plate 4 is rotatably connected with the upper end of the upper footrest 5, the lower end of the upper footrest 5 is rotatably connected with the upper end of the lower footrest 6, and the lower frame of the surrounding frame 1 The bottom of 12 is also fixedly provided with connecting frame 13, and connecting frame 13 is positioned at surrounding frame 1 rear, and the lower end of lower footrest 6 is connected on the bottom end of connecting frame 13 rotationally, and under seat pocket state, this connecting frame 13 can be used for Placement of feet for sitters.

In this embodiment, two sets of electric bells 7 are used as the locking mechanism, and these two sets of electric bells 7 are arranged at the connection between the lower end of the upper footrest 5 and the upper end of the lower footrest 6 . Referring to Fig. 2, each group of electric bells 7 includes a first electric bell cover 71 and a second electric bell cover 72 that can rotate relative to each other, the first electric bell cover 71 is fixed on the upper end of the lower footrest 6, and the second electric bell cover 72 is fixed on the upper footrest 5 lower end, the first electric bell cover 71 inner chamber is fixedly provided with the pin shaft 74 that axis line distributes along the left and right direction of the seat frame, the second electric bell cover 72 is rotatably arranged on the pin shaft 74, and the electric bell 7 also includes The electric bell gear 73 that is sleeved on the pin shaft 74 in an axial sliding manner has at least one radially outwardly protruding gear tooth on the circumferential direction of the electric bell gear 73, and a first electric bell cover 71 is provided with a first The chute, the inner peripheral part of the second electric bell cover 72 is provided with a second chute, and the gear teeth of the electric bell gear 73 can be inserted into the first chute and the second chute correspondingly in the axial direction. The inner cavity of the first electric bell cover 71 is also provided with a spring (not shown) for providing the elastic recovery force of the electric bell gear 73 in the axial direction, and an electric bell button 75 is also provided on the outer end of the second electric bell cover 72 . The bell button 75 has a protrusion that can pass through the second chute and push the bell gear 73 to move axially. The electric bell 7 has two working states: locked state and unlocked state. When the electric bell 7 is in the locked state, the electric bell gear 73 is under the elastic force of the spring, and the two ends of the upper gear teeth of the electric bell gear 73 are accommodated in the first slide respectively. In the groove and the second chute, like this, the first electric bell cover 71 and the second electric bell cover 72 can not rotate relatively because of the electric bell gear 73; The protrusion pushes the electric bell gear 73 to overcome the elastic force of the spring and moves axially towards the first electric bell cover 71. When the gear teeth on the electric bell gear 73 break away from the second chute, the first electric bell cover 71 and the second electric bell The cover 72 can rotate relatively, and now the upper footrest 5 and the lower footrest 6 can rotate relatively.

Referring to Figures 1 to 3, when the seat of the stroller is in the seat state, the seat plate 4 is placed approximately in a horizontal direction, and the back plate 3 and the seat plate 4 form a certain angle of inclination so that the child can sit and stand on the seat. When the board 4 is on, it is for children to lean on their backs. The upper end of the back board 3 is supported by a seat cover (not shown) that is sheathed on the seat frame, and the upper footrest 5 and the lower footrest 6 are approximately in the same plane and Seat plate 4 is at a certain angle so that its legs are shelved conveniently when children sit and stand on seat plate 4, and the above-mentioned state of upper footrest 5, lower footrest 6 and seat plate 4 is locked by electric bell 7. When the seat pocket of the baby stroller needs to be converted into a sleeping basket state, as shown in Fig. 4 and Fig. 5, the operator only needs to press the bell button 75 on both sides of the bell 7 to unlock the bell 7, and the upper footrest 5 and the lower The footrest 6 rotates relative to each other, the seat plate 4 rotates around the rotating shaft 21, and the back plate 3 is adjusted to be roughly parallel to the surrounding frame 1. The back plate 3, the seat plate 4, and the upper footrest 5 are roughly located on the same plane. The upper footrest 5 and the lower footrest 6 are roughly in a vertical state, and now the surrounding frame 1 can be placed horizontally to form a sleeping basket for children to lie on. In this way, the backboard 3, the seat board 4 and the upper footrest 5 form the bottom board for children to lie on the sleeping basket, which has good rigidity and can be used for children to lie down for a long time without deformation, and has a good use comfort.

In order to ensure the relative position of the seat plate 4 and the upper footrest 5 in the seat pocket state and the sleeping basket state, the seat plate 4 is also provided with a limiter 8 for limiting the rotational position of the upper footrest 5 relative to the seat plate 4 , as shown in Figure 2, the limiting member 8 has two limiting positions to ensure that the seat plate 4 and the upper footrest 5 are set at a certain angle in the seat pocket state, and that the seat plate 4 and the upper footrest are in the sleeping basket state. 5 are roughly located in the same plane, improving the comfort for children to use. The state transition process between the seat pocket and the sleeping basket is simple and convenient, and has good usability.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention shall fall within the protection scope of the present invention.
