As shown in fig. 1 to 5, a folding mechanism for children's products, in this case, a tricycle for children is taken as an example of the children's products, but the children's products may be other children's toy products;
the children riding tricycle comprises a first rod, a second rod and a third rod, wherein the first rod and the second rod are handles 11 which are used for holding children at the left side and the right side of the children riding tricycle, and the third rod is a front support 12 of the children riding tricycle; the front frame 12 and the handles 11 on both sides have a folded state in which they are close to each other and an unfolded state in which they are away from each other. The handles 11 on the two sides are rotatably connected with the front support 12 through the folding mechanism, so that the handles 11 on the two sides and the front support 12 can be rotated, folded and closed, and a foundation is provided for the final folding of the tricycle ridden by children.
In this example, only one rotation direction is provided for each of the handles 11 on both sides, the rotation axes of the handles 11 on both sides are located on the same plane, and the angle between the rotation axes is 152 °, in the case that only one rotation direction is provided for each of the handles 11 on both sides, the rotation axes of the handles 11 on both sides are not on the same straight line, but form an angle therebetween, and during rotation, the handles 11 on both sides can rotate obliquely, and one rotation can realize that both rotate relative to each other and rotate together with the front bracket 12.
Certainly, the handles 11 on both sides can be moved close to each other, and the two can be rotated and moved close to the front bracket 12, the handles 11 on both sides can also be respectively provided with two rotating directions, in one rotating direction, the handles 11 on both sides can be moved close to each other, and in the other rotating direction, the handles 11 on both sides can be moved forward and moved close to the front bracket 12; alternatively, the end of each handle 11 and the side of the connecting body 20 are respectively set to be connected in a ball-end universal rotation manner, so that the rotation approach scheme can still be realized.
Specifically, the folding mechanism includes a connecting assembly connected between the front bracket 12 and the ends of the handles 11 on both sides, and a locking structure for stabilizing the handles 11 on both sides and the front bracket 12 in the unfolded state, the connecting assembly is specifically a connecting body 20, and the front bracket 12 is slidably connected with the connecting body 20;
as shown in fig. 6, fixing surfaces m1 are respectively formed on two opposite sides of the connecting assembly, the fixing surfaces m1 on the two sides are neither parallel to nor perpendicular to the horizontal plane, nor parallel to nor perpendicular to the vertical plane, and corresponding surfaces m2 matched, butted and attached with the fixing surfaces m1 on the two sides are respectively formed at the end parts of the handles on the two sides. When the handle rotates, the fixing surface m1 and the matching surface m2 are always attached.
As shown in fig. 4, a connecting shaft is fixed on the connecting body 20, the connecting shaft has a fixing portion 211 fixed on the inner periphery of the connecting body 20, and rotating shaft portions 212 extending from both ends of the fixing portion to both sides, the rotating shaft portions 212 on both sides are symmetrically arranged, and the handles 11 on both sides are rotatably connected with the rotating shaft portions 212 on both sides, that is, the rotating connection relationship between the handles 11 on both sides and the connecting body 20 is realized.
The locking structure comprises a first locking assembly arranged between the connector and the front support and a second locking assembly arranged between the handle and the front support, the second locking assembly comprises a clamping portion arranged on the handles 11 on the two sides and a matching portion arranged on the front support 12 and capable of matching with the clamping portion in a clamping mode, the specific clamping portion is a convex column 201 arranged at the end portion of the handles 11 on the two sides and close to each other, and the matching portion is a clamping hole 202 arranged on the front support 12. When the connecting body 20 slides to one side far away from the front bracket 12, that is, the connecting body 20 slides upwards, the clamping portion and the matching portion can be separated from the clamping, that is, the convex column 201 is separated from the clamping hole 202, at this time, the locking structure is unlocked, and then the handles 11 and the front bracket 12 on both sides can rotate mutually to be drawn close to the folding state. The first locking assembly is used for preventing children from easily lifting the handle upwards, namely the second locking assembly can be prevented from being unlocked accidentally, and accidents are avoided.
The utility model discloses the handle 11 and the folding operational aspect of fore-stock 12 of both sides are as follows: firstly, the handle 11 is held, the handle 11 is slightly lifted upwards, so that the connecting body 20 is driven to slide upwards, or the connecting body 20 is directly lifted, so that the convex column 201 is separated from the clamping hole 202, at the moment, the locking structure releases the locking of the relative positions of the handles 11 on the two sides and the front support 12, namely, the handles 11 on the two sides can be rotated, the handles 11 on the two sides respectively rotate around the rotating shaft parts 212 on the two sides, so that the handles 11 on the two sides rotate and are closed to each other, and meanwhile, the handles rotate and are closed to the front support 12 forwards until the folding is completed.
In addition, as shown in fig. 5, the tricycle for children to ride in this embodiment includes, in addition to the front frame 12 and the handles 11 on both sides, a main frame 100 and a rear frame 101 rotatably connected to the rear portion of the main frame 100, wherein the upper portion of the front frame 12 is rotatably sleeved with a rotating body 30, and the rotating axes of the rotating body 30 and the front frame 12 extend in the up-down direction of the tricycle for children to ride, so as to drive the front frame 12 and the front wheels to steer when the handles are operated; in addition, the rotating body 30 is rotatably connected with the front end of the main frame 100, and the rotating axes of the rotating body and the main frame extend along the left and right directions of the tricycle ridden by the child, so that the handle 11, the front frame 12 and the front wheel can be moved together towards the main frame 100, that is, after the front frame 11 and the handle 11 are moved together, the front frame 11 and the rear frame 101 can be moved together, and the tricycle ridden by the child can be folded to be smaller.
To sum up, the utility model discloses children's articles for use actually are children's tricycle of riding, through the utility model discloses a folding mechanism's setting both can ride the tricycle of riding when using with the handle and the fore-stock locking of both sides at expansion state, can ride the tricycle of riding again at children when folding up, removes the relative locking to both sides handle and fore-stock to make both sides handle can draw close relatively the fore-stock and fold up and have can draw close each other on left and right sides direction, ride the tricycle of riding for children and fold up and provide the prerequisite guarantee for a short time.
