Description

Technical Field

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

[0002] With economic development and the continuous improvement of people's living standards, my country's baby products industry has developed very rapidly. Products are diversified, including strollers, high chairs, and swings, all featuring baby seats for infants.

[0003] Existing baby seats typically include a seat frame and a seat cover mounted on the seat frame. The seat frame includes a seat post, a backrest frame whose lower end is pivotally connected to the seat post, and an angle locking mechanism located between the backrest frame and the seat post. This angle locking mechanism can lock the backrest frame in multiple angle positions, such as sitting, semi-reclining, and lying down. The seat surface size remains the same in all these sitting angle positions. For example, the seat surface cannot be enlarged in the lying down position to provide a larger and more comfortable reclining space.

[0004] Therefore, it is necessary for this invention to propose a baby seat that can adjust the size of the seat surface as the angle of the backrest changes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a baby seat.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an infant seat, including a seat frame, the seat frame including a seat post, an adjustable backrest, a seat frame and a connecting rod rotatably connected to the lower part of the backrest about a first axis, the seat post being slidably mounted on the seat frame in the front-back direction, the front end of the connecting rod being rotatably connected to the front part of the seat post about a second axis, the rear end of the connecting rod being rotatably connected to the lower part of the backrest about a third axis, and an angle locking mechanism being provided between the backrest and the seat frame.

[0007] In some embodiments, as the backrest frame rotates about the first axis, the third axis moves circumferentially along the first axis.

[0008] In some embodiments, the line connecting the second axis and the third axis, and the seat post frame form an angle α, and the backrest frame and the seat post frame form an angle β. When the backrest frame is rotated backward to increase the angle β, the angle α decreases, and the seat post frame moves forward and extends relative to the seat frame. When the backrest frame is rotated forward to decrease the angle β, the angle α increases, and the seat post frame moves backward and retracts relative to the seat frame.

[0009] In some embodiments, the seat frame includes seat side panels located on the left and right sides, and the lower parts of the left and right sides of the backrest frame each have a forward-protruding backrest adapter plate. Each backrest adapter plate is rotatably connected to the seat side panel via a first axis, and the rear end of the connecting rod is rotatably connected to the lower rear part of the backrest adapter plate about a third axis.

[0010] In some embodiments, the line connecting the second axis and the third axis is located between the first axis and the front and rear center lines of the seat frame.

[0011] In some embodiments, the seat post frame is frame-shaped, and the lower part of the seat side panel is respectively fitted onto the side seat post of the seat post frame.

[0012] In some embodiments, the lower parts of the left and right seat side panels are connected as a whole by a seat crossbar.

[0013] In some embodiments, the outer sides of the two seat side panels are respectively provided with seat connectors for mounting to the seat mounting base.

[0014] In some embodiments, a control button is provided on the top of the backrest to control the unlocking of the corner locking mechanism.

[0015] The technical problem to be solved by this utility model is to provide a children's stroller.

[0016] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a child stroller, including an infant seat as described in any one of the above, including a stroller frame, wherein seat mounting seats are respectively provided on the left and right side supports of the stroller frame, and the infant seat can be detachably installed between the two side seat mounting seats.

[0017] The scope of this utility model is not limited to technical solutions formed by specific combinations of the above-mentioned technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-mentioned technical features or their equivalent features. For example, technical solutions formed by substituting the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides an infant seat, in which the seat post and seat frame form a front-to-back telescopic mechanism, and together with the backrest frame and connecting rod, form a linkage mechanism. By adjusting the rotation angle of the backrest frame around the first axis, the displacement of the third axis is driven, thereby driving the seat post to move back and forth relative to the seat frame. Since the seat post and the seat frame form a seat surface, the size of the seat surface of the seat can be adjusted synchronously by adjusting the relative angle of the backrest frame.

[0019] When the backrest is reclined flat, the angle relative to the seat post is at its maximum. The forward movement of the third axis causes the connecting rod to push the seat post forward, resulting in the largest seat surface. When the backrest is folded forward, the angle relative to the seat post is at its minimum. The backward movement of the third axis causes the connecting rod to pull the seat post backward, resulting in the smallest seat surface. Attached Figure Description

[0026] An infant seat, typically detachably mounted on the stroller frame of a stroller, the chair frame of a high chair, or the swing chair frame, usually includes a seat frame and a fabric cover over the seat frame, the fabric cover not shown in the drawing.

[0027] like Figure 1-4 As shown, the seat frame includes:

[0028] The seat pole frame 1 is a frame-shaped structure made of metal rods, including side seat poles 11 that extend along the center lines of the left and right sides.

[0029] The seat frame 3 and the seat post frame 1 are slidably mounted on the seat frame 3 in the front-back direction. The seat frame 3 includes seat side plates 31 located on the left and right sides, and at least one seat crossbar connected between the lower parts of the left and right seat side plates 31 to form a whole. The side seat posts 11 extending in the front-back direction on the left and right sides of the seat post frame 1 are slidably inserted into the lower part of the corresponding seat side plates 31, and the lower part of each side seat side plate 31 is sleeved on the corresponding side seat post 11.

[0030] Backrest frame 2, the lower part of backrest frame 2 is rotatably connected to seat frame 3 around the first axis X1, the lower parts of the left and right sides of backrest frame 2 respectively have forward protruding backrest adapter plates 21, each backrest adapter plate 21 is movably connected to seat side plate 31 through the first axis X1, and a corner locking mechanism is provided between each backrest adapter plate 21 and seat side plate 31.

[0031] Link 4, there are two links, located on the left and right sides respectively. The front end of link 4 is rotatably connected to the front part of the side seat rod 11 of the seat rod frame 1 around the second axis X2. The lower part of the backrest adapter plate 21 has a protruding link joint 22. The rear end of link 4 is rotatably connected to link joint 22 around the third axis X3.

[0032] As shown in the attached figures, the line connecting the second axis X2 and the third axis X3 is located between the first axis X1 and the front-rear center line CL of the seat post 11 on the side of the seat post 1. When the backrest 2 rotates around the first axis X1, the third axis X3 moves circumferentially along the first axis X1. The line connecting the second axis X2 and the third axis X3 forms an angle α with the front-rear center line CL of the seat post 11 on the side of the seat post 1. An angle b is formed between the backrest 2 and the front-rear center line CL of the seat post 11 on the side of the seat post 1. When the backrest 2 is rotated clockwise backward to increase the angle b, the third axis X3 moves clockwise forward and downward around the second axis X2, making the angle α smaller. The seat post 1 is pushed forward relative to the seat post 3. When the backrest 2 is rotated counterclockwise forward to decrease the angle b, the third axis X3 moves counterclockwise backward and upward around the second axis X2, making the angle α larger. The seat post 1 is pulled backward relative to the seat post 3. The seat frame and the seat frame together form the seat surface. By adjusting the angle of the backrest frame, the size of the seat surface can be adjusted simultaneously. When the backrest frame angle is at its maximum, the seat surface is at its maximum. When folded down, the backrest frame angle is at its minimum, and the seat surface is at its minimum.

[0033] The top of the backrest is equipped with a control button for unlocking the corner locking mechanism. The control button is usually connected to two traction cables, which are connected to the corresponding corner locking mechanism. The corner locking mechanism is not the focus of this invention. Any mechanism that can lock two rotating joints can be used. For example, multiple locking holes are distributed around the first axis on the seat side panel 31. Elastic locking tongues are telescopically set at the lower end of the corresponding backrest frame 2 and connected to the corresponding traction cables. When the elastic locking tongue is inserted into a certain locking hole, the backrest frame 2 is positioned. After the elastic locking tongue is withdrawn from all locking holes, the backrest frame 2 can rotate.

[0034] (No illustration shown) An example of an infant seat application, where the infant seat is installed on a stroller. A stroller typically includes an unfoldable or foldable frame, a front wheel assembly, and a rear wheel assembly. The inner sides of the left and right side supports of the stroller frame each have a seat mounting bracket, with the seat mounting brackets facing upwards when the stroller frame is in the unfolded position. Seat connectors 32 are respectively provided on the outer sides of the two seat side panels 31 of the infant seat.

[0035] When the baby seat is installed between the seat mounts on both sides of the stroller frame, the corresponding seat connector 32 is inserted downwards into the seat mount, and the two are locked together by a locking mechanism. The locking mechanism then allows the baby seat to be removed from between the two seat mounts. This is the existing structure and will not be described in detail.

[0036] When the stroller frame is folded, if the baby seat is installed on the stroller frame, the baby seat can be folded independently.
