Description

Technical Field

[0001] This utility model relates to the field of luggage, and more specifically, to a children's luggage. Background Technology

[0002] In scenarios involving children's travel, the dual needs of carrying belongings and supervising children create numerous inconveniences for parents. Traditional children's rolling suitcases are single-function, focusing solely on storage and failing to assist parents in supervising their children during outings. If a child is too tired to walk, the parent must carry them, increasing the burden. Some designs that attempt to incorporate riding functionality have structural flaws: either the riding area is poorly designed and not conforms to children's body characteristics, resulting in poor comfort and safety, such as the suitcase's size and shape not fitting a child's sitting posture, making it easy for the child to slip off; or the pull rod structure still uses the traditional stretch type, with limited design length, and because the suitcase cannot be tilted while the child is riding, the child needs to pull the handle. The pull handle, when positioned directly on the ground, compromises the integrity of the suitcase's riding function and lacks reliable fixation, making it prone to wobbling and loosening during use. Furthermore, when riding, parents find it difficult to easily move the child and suitcase together using the convenient pull handle structure; the operation is laborious and lacks stability. This fails to meet the combined needs of children's travel—both "riding assistance" and "easy pushing"—and necessitates innovative design to address issues such as the suitcase's limited functionality, poor riding experience, and low compatibility between the pull handle and riding functions. This would improve the convenience and enjoyment of children's travel and reduce the burden on parents. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a children's suitcase.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a children's suitcase, including a suitcase body and a pull rod, wherein the bottom surface of the suitcase body is provided with a plurality of rollers, the suitcase body is short and long, and the sides of the suitcase body are respectively provided with grooves for accommodating children's thighs, the grooves being adapted to the children's thigh area; The pull rod is U-shaped, and the top edge of the box has a storage groove for storing the pull rod. The two ends of the pull rod are rotatably connected to the two ends of one side edge of the top surface of the box and can be flipped into the storage groove. The box is equipped with a fastener for securing the pull rod when it is in the stowed state; A flexible handle is provided in the center of the top surface of the box, and a handle groove is provided on the top surface of the box to accommodate the flexible handle. When the flexible handle is accommodated in the handle groove, its surface is not higher than the top surface of the box. When the lever is in use, it flips to the front of the box, allowing the child to ride on it with their thighs placed in the side slots. Parents can move the box and the child by holding the lever.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0014] A type of children's suitcase, such as Figure 1 and Figure 2 As shown, the device includes a box body 1 and a pull rod 2. The bottom of the box body 1 is equipped with several casters 3 for easy movement. The box body 1 is low and long, a design that facilitates child riding. Both sides of the box body 1 have grooves 4 to accommodate a child's thighs. The size of the grooves 4 is adapted to the child's thigh area, making the ride more stable and comfortable. The grooves 4 allow for a wider design of the box body 1 without affecting the child's riding experience, while also accommodating more items. The low and long design of the box body 1 lowers its center of gravity, and combined with the grooves 4 on both sides adapted to the child's thighs, it conforms to the child's body proportions while riding and also prevents the child from slipping, improving riding stability and safety.

[0015] like Figure 2 and Figure 3As shown, the pull rod 2 is U-shaped. The top edge of the housing 1 has a storage groove 5 for storing the pull rod 2. Both ends of the pull rod 2 are rotatably connected to the two ends of one edge of the top surface of the housing 1, allowing it to be flipped into the storage groove 5. The housing 1 has a fixing member 6 for securing the pull rod 2 in its stored state. The fixing member 6 contains a hidden magnet 19. Corresponding to the fixing member 6, the pull rod 2 has a magnetic coupling member 20 that attracts the hidden magnet 19. The magnetic coupling member 20 can be a metal sheet or a magnet. In this embodiment, the magnetic coupling member 20 is a magnet. The magnetic coupling member 20 is adhered to the pull rod 2 by slotting the surface of the pull rod 2, resulting in a smooth transition between the magnetic coupling member 20 and the surface of the pull rod 2. When the pull rod 2 is flipped into the storage groove 5 and in its stored state, the hidden magnet 19 in the fixing member 6 and the magnetic coupling member 20 on the pull rod 2 are magnetically attracted, thus securing the pull rod 2 in its stored state. The U-shaped pull rod 2 fits the gripping habits of parents, and the flip design solves the problem of operation interference in riding scenarios caused by traditional pull rod 2. The storage slot 5 can completely store the pull rod 2, preventing it from protruding and affecting the stacking of the case 1 or the child's riding when not in use. The hidden magnet 19 in the fixing part 6 forms a reliable attraction with the magnetic matching part 20 on the pull rod 2, realizing the stable fixation of the pull rod 2 in the stored state and preventing the pull rod 2 from coming out of the storage slot 5 when the case 1 is moved. Compared with mechanical buckles, the magnetic structure is more convenient to operate, and parents can complete the storage and release of the pull rod 2 with one hand.

[0016] Furthermore, such as Figure 2 and Figure 4As shown, the pull rod 2 is a telescopic structure, including two parallel telescopic support rods and a gripping crossbar 14 connected to the top of the two telescopic support rods. The end of the telescopic support rod away from the gripping crossbar 14 is rotatably connected to the edge of the top surface of the housing 1. The telescopic support rod includes an outer tube 15 and an inner tube 16. The inner tube 16 is slidably inserted into the outer tube 15, and the sliding range of the inner tube 16 can be limited by the limiting structure commonly used by those skilled in the art at the inner end of the inner tube 16 and the opening of the outer tube 15. The inner tube 16 has an elastic limiting protrusion 17 on its tube wall for positioning the telescopic position of the inner tube 16, and the outer tube 15 has positioning holes 18 spaced along its length that are adapted to the elastic limiting protrusion 17. The design of the elastic limiting protrusion 17 on the inner tube 16 and the positioning holes 18 spaced along the length of the outer tube 15 can accurately realize the telescopic positioning of the inner tube 16 relative to the outer tube 15. The inner tube 16, as a movable component, integrates the elastic limiting protrusion 17, reducing the structural complexity of the inner wall of the outer tube 15 and simplifying its processing. Simultaneously, this layout allows the elastic limiting protrusion 17 to move synchronously with the inner tube 16, providing more flexible positioning when engaged with the positioning hole 18 on the outer tube 15. This allows for stable fixation at different telescopic positions according to actual needs, meeting the length requirements of parents of varying heights to hold the pull rod 2 and improving pushing comfort. After the pull rod 2 is flipped to its usability, its length is adjusted through the positioning structure of the inner tube 16 and outer tube 15, ensuring ease of pushing for parents without affecting its storage in the storage slot 5. In existing technology, similar elastic limiting protrusion 17 structures are widely used in telescopic poles, folding furniture, and other fields. Their core principle is to achieve a reciprocating "lock-and-release" action through the deformation of elastic components. Examples include the positioning buckle of an umbrella rib and the limiting protrusion of a mop telescopic pole, both relying on elastic deformation to achieve positional fixation. In this embodiment, the elastic limiting protrusion 17 on the inner tube 16 wall adopts the same structure, consisting of a hemispherical protrusion and an elastic element, which is a structure well known to those skilled in the art, so it will not be described in detail here.

[0017] like Figure 1 As shown, a flexible handle 7 is provided in the center of the top surface of the box 1. A handle groove 8 is provided on the top surface of the box 1 to accommodate the flexible handle 7. The width of the middle part of the handle groove 8 is greater than the width of the two ends, forming an expanded area for fingers to insert. When it is necessary to pull up the flexible handle 7, fingers can be inserted into this expanded area to contact the flexible handle 7 and apply pulling force. Furthermore, when the flexible handle 7 is accommodated in the handle groove 8, its surface does not exceed the top surface of the box 1, thus not affecting children's riding comfort. The flexible handle 7 facilitates carrying the box 1, and the embedded design ensures that its surface does not exceed the top surface of the box 1, preventing pressure on children due to a protruding handle while riding, thus balancing carrying functionality and riding comfort.

[0018] like Figure 2As shown, the pull rod 2 is rotatably connected to the box body 1 via a plastic connecting seat 9. The plastic connecting seat 9 is embedded in the corresponding mounting groove 10 of the box body 1 and fixed by heat fusion, making the connection between the pull rod 2 and the box body 1 more secure. The top of the roller 3 is provided with a plastic connecting seat 11, which is embedded in the mounting groove 12 on the bottom surface of the box body 1 and fixed by heat fusion, ensuring that the roller 3 can stably drive the box body 1 to move. The fixing part 6 is made of plastic and is embedded in the mounting groove 13 of the box body 1 and fixed by heat fusion. The mounting grooves 10, 12, and 13 are all integrally injection molded with the box body 1 through a mold, enhancing the stability of the overall structure. Plastic connector 9 and plastic connector 11 provide stable support for the rotation of pull rod 2 and roller 3, respectively. The hot-melt connection makes the accessories and the box body 1 form a mechanical whole, preventing the accessories from loosening due to vibration when the child is riding. The mounting groove is integrally injection molded with the box body 1, which enhances the structural strength of the box body 1 and can withstand the continuous pressure from the child's weight. By strengthening the connection strength between pull rod 2, roller 3 and box body 1, the functional stability of the parent driving the box body 1 and the child by pull rod 2 is ensured, and structural failure after long-term stress is prevented.

[0019] Furthermore, such as Figure 1 and Figure 2 As shown, all edges of the box body 1 are rounded. The corresponding parts of the plastic connecting seat 11, plastic connecting seat 21, and fastener 6 on the edges of the box body 1 are also rounded, and they are adapted to the rounded transition of the edges of the box body 1. The rounded transition of the edges of the box body 1 and accessories eliminates sharp corners and reduces the risk of bumps and knocks when children ride on or get on and off the box body 1. The rounded compatibility between the connecting seat and the box body 1 ensures a smooth transition and avoids scratches caused by local protrusions.

[0020] When the lever 2 is in use, it flips to the front of the box 1, allowing the child to ride on the box 1 with their thighs inside the side slots 4. Parents can move the box 1 and the child by holding the handle bar 14 of the lever 2, thus meeting the combined needs of "riding assistance + convenient pushing" when children travel.
