[0024] The foldable infant swing is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1: Figures 1-4 The foldable baby swing shown in the figure comprises a main support frame 1 which can be unfolded or folded, and a seat mechanism. The main support frame 1 comprises left and right side brackets 11, and the seat mechanism is arranged between the left and right side brackets 11.

[0026] The side bracket 11 on each side includes a front leg 111, a rear leg 112, and a top mounting seat 113 located at the top, and at least one of the upper ends of the front leg 111 and the upper ends of the rear leg 112 is pivotally connected to the top mounting seat 113. In this embodiment, the front legs on each side are respectively pivotally connected to the corresponding top mounting seat 113 around the sixth axis X6, and the rear legs on each side are respectively pivotally connected to the corresponding top mounting seat 113 around the seventh axis X7, and the sixth axis X6 and the seventh axis X7 extend in the left and right directions respectively.

[0027] The supporting main frame 1 also includes a bottom support frame 12 located at the bottom, and the bottom support frame 12 is arranged between the bottoms of the front legs 111 on both sides and the rear legs 112 on both sides. In detail, the bottom support frame 12 includes a lifting seat 121 located in the center, and four pulling rods 122 whose one ends are respectively pivotally connected to the lifting seats 121, and the other end of each pulling rod 122 is pivotally connected to the corresponding lower end of the front leg 111 or the lower end of the rear leg 112, wherein the axial center lines of the two ends of the four pulling rods 122 are respectively tangent to the circumferential direction with the center of the lifting seat 121 as the center.

[0028] The supporting main frame 1 further includes a foldable cross brace 13 which is arranged between the tops of the two side brackets 11 and can be folded or expanded in the left and right directions.

[0029] The folding cross brace 13 includes two cross brace rods 131 whose one ends are respectively pivotally connected to the corresponding top mounting seats 113 about the five-axis X5. The five-axis X5 extends in the front-rear direction. The other ends of the two cross brace rods 131 are rotatably connected through an upward top limiting joint 132 before. The upward top limiting joint 132 is a one-way rotation limiting joint. When the support main frame 1 is in the unfolded position, the upward top limiting joint 132 restricts the other ends of the cross brace rods 131 from further moving upward. The specific structure of the one-way rotation limiting joint is not the key point of the present utility model. As long as when the folding cross brace 13 is in the unfolded position, the connection between the two cross brace rods 131 only allows downward movement and cannot move further upward, that is, upward movement is limited and locked in the unfolded position. In this embodiment, the other ends of the two cross brace rods 131 form two pivot points on the upward top limiting joint 132, and the axis lines are respectively parallel to the two five-axes X5 on both sides. There is no illustration. It is also possible that the other ends of the two cross brace rods 131 are directly pivotally connected, and the upward top limiting joint 132 is fixed on the other end of one of the cross brace rods 131.

[0030] The support main frame 1 also has a locking mechanism for locking it in the unfolded position. Theoretically, this locking mechanism can be set at any turning point to lock the support main frame 1 in the unfolded position. In this embodiment, the locking mechanism is set on the folding cross brace 13 to lock the folding cross brace 13 in the unfolded position, thereby locking the spatial position between the left and right side brackets and making the position more conducive to operation.

[0031] As for the specific structure of the locking mechanism, it is not the key point of the present utility model. As long as it is a structure that can lock between two rods with a rotational relationship, it can be applied here and will not be elaborated. In this embodiment, the locking mechanism is set on the upward top limiting joint 132 to control the relative rotation or fixation of the two cross brace rods 131 respectively.

[0032] The seat mechanism includes a seat frame 2 that can be folded or unfolded respectively in the front-rear direction and the left-right direction, and a seat cloth cover sleeved on the seat frame 2. There is no illustration of the cloth cover. The seat frame 2 is installed between the top mounting seats 113 of the left and right side brackets 11.

[0033] The seat frame 2 includes seat side frames 21 located on the left and right sides respectively, a front seat brace 22 located in the front, and a rear seat brace 23 located in the rear.

[0034] The chair side frame 21 on each side includes a chair side base 211, a swing rod 212 whose lower end is fixedly connected to the chair side base 211, a front rod 213 and a rear rod 214 whose lower ends are respectively pivotally connected to the chair side base 211 and are located on both sides of the swing rod 212, one in front of the other. The lower end of the front rod 213 on each side is pivotally connected to the corresponding chair side base 211 around the third axis X3, and the lower end of the rear rod 214 on each side is pivotally connected to the corresponding chair side base 211 around the fourth axis X4. The third axis X3 and the fourth axis X4 extend in the left and right directions respectively.

[0035] The front and rear sides of the chair side base 211 on each side respectively have supporting parts that can stably keep the corresponding front side rod 213 and the rear side rod 214 in the unfolded position.

[0036] The upper end of the rocker arm 212 is rotatably connected to the top mounting seat 113. In this embodiment, at least one of the top mounting seats 113 on both sides is provided with a power driving mechanism for driving the corresponding rocker arm 212 to swing back and forth around the pivot electrically to realize an electric rocking chair. The top mounting seat 113 can also be provided with a music sounding device to increase the fun.

[0037] The front seat support 22 is located between the upper ends of the front side rods 213 on the left and right sides and can be folded or expanded in the left and right directions. It includes two front support rods 221, one end of which is pivotally connected to the corresponding upper ends of the front side rods 213 around an axis X1. The other ends of the two front support rods 221 are rotatably connected through a front downward limit joint 222, and the axis X1 is perpendicular to the three axes X3 in space.

[0038] The seat rear support 23 is located between the upper ends of the rear side rods 214 on the left and right sides and can be folded or expanded in the left and right directions. It includes two rear support rods 231, one end of which is respectively connected to the corresponding upper end of the rear side rods 214 around the second axis X2. The other ends of the two rear support rods 231 are rotatably connected through a rear downward limiting joint 232. The second axis X2 is perpendicular to the fourth axis X4 in space.

[0039] Among them, the above-mentioned front downward limit joint 222 and rear downward limit joint 232 can all refer to the aforementioned top upper limit joint 132, and are both a one-way rotation limit joint. For example, when the supporting main frame 1 is in the unfolded position, the front downward limit joint 222 limits the other end of the front support rod 221 from continuing to move downward, that is, the front seat support 22 in the unfolded position can support the weight of the child's legs, and upward movement is allowed, so that it can be folded; similarly, the rear downward limit joint 232 limits the other end of the rear support rod 231 from continuing to move downward, that is, the rear seat support 23 in the unfolded position can support the weight of the child's head, and upward movement is allowed, so that it can also be folded; the specific structure of the one-way rotation limit joint is not the key point of the utility model and will not be repeated here.

[0040] The seat cover is arranged between the front side rods 213 on both sides, the rear side rods 214 on both sides, the front seat support 22, and the rear seat support 23 to form a human body support layer.

[0041] The folding cross brace 13 is in an arc shape that is located above the seat cloth cover in the expanded state, spanning the left and right directions and arching upward, so that there is a larger space for human body movement.

[0042] Folding principle:

[0043] The seat rear support 23 can be flipped forward and upward to unlock the locking mechanism on the folding cross support 13, and the upper limit joint 132 can be pressed downward to make the folding cross support 13 collapse in the left and right directions, while the lifting seat 121 of the bottom support frame 12 is lifted upward, or force can be directly applied between the front supporting legs 11 and the rear supporting legs on each side to make the two come together, so that the lifting seat 121 arches upward, so that the front supporting legs 111 on both sides and the rear supporting legs 112 on both sides are synchronously collapsed toward the center of the lifting seat 121, that is, the support main frame 1 is folded in the left and right directions and the front and back directions as a whole. In this process, under the premise of collapsing in the left and right directions, the seat front support 22 and the seat rear support 23 automatically follow the left and right directions to fold, so that the entire children's swing is folded as a whole.

[0044] Unfolding principle:

[0045] The same is true in reverse. When the upper limit joint 132 is pulled upward, the left and right side brackets are stretched open, causing the lifting seat 121 to automatically move downward, thereby further prompting the front legs 111 on both sides and the rear legs 112 on both sides to synchronously move away from the center of the lifting seat 121. For safety reasons, the lifting seat 121 can be stepped on, so that the front legs 111 on both sides and the rear legs 112 on both sides are synchronously stretched open relative to the lifting seat 121, that is, the support main frame 1 is unfolded as a whole in the left and right directions and the front and back directions. When unfolded into place, the locking mechanism on the folding cross brace 13 is automatically locked. In this process, under the premise of being stretched open in the left and right directions, the front seat support 22 and the rear seat support 23 automatically follow the unfolding, so that the entire child swing is unfolded as a whole.

[0046] Embodiment 2: The difference between this embodiment and embodiment 1 lies in the seat mechanism. In this embodiment, an integrated bench can also be used, and both sides of the bench are directly hung on the top mounting seat by hanging ropes, so as to facilitate manual pushing of the seat mechanism.

[0047] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
