Description

Technical Field

[0001] This utility model relates to the field of children's scooters, and in particular to a children's scooter with an adjustable seat. Background Technology

[0002] A children's scooter is a recreational tool designed for children aged 3 and above. It is propelled by body swinging or foot pushing, which can improve balance, coordination and reaction ability, as well as enhance lower limb strength. Its core structure includes handlebars, frame, wheels and seat. Some models are also equipped with brakes and folding function, taking into account both safety and portability.

[0003] Chinese patent CN217022779U discloses a height-adjustable children's scooter. By connecting the upright tube and the threaded rod in a threaded manner, the handlebars can be precisely adjusted to the most comfortable height.

[0004] However, in the above solution, one end of the seat is mounted on the riser via a fixing sleeve, and the other end is fixed by a support rod. Changing the position of the fixing sleeve on the riser changes the height of the seat. The riser and the fixing sleeve are connected by a pin, and the riser has several limiting holes. To ensure the support strength of the riser, the distance between the limiting holes is relatively large, usually 5cm, so that the seat height can be adjusted by at least 5cm at a time. However, children's height increases continuously, which can lead to children's legs not being able to bend naturally when on the seat. This results in the seat height of the children's scooter being limited and difficult to match with the child's height, leading to insufficient comfort. Therefore, a children's scooter with an adjustable seat is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a children's scooter with an adjustable seat, in order to solve the problem mentioned in the background art that the adjustable height of the seat in children's scooters is limited, making it difficult to match with the height of children and resulting in insufficient comfort of the scooter. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable seat children's scooter includes a base and a seat. The base has a recessed space in the middle, and the seat is housed inside the recessed space. A load-bearing plate is provided below the seat, and a first support rod and a second support rod are provided below the load-bearing plate. A rear fixing plate and a front fixing plate are provided at both ends of the base. A rear wheel is provided on one side of the rear fixing plate, and a limit plate is provided on one side of the front fixing plate. A sleeve is provided between the two limit plates, and a steering column is provided inside the sleeve. The steering column is connected to the sleeve bearing. A handlebar and a front wheel are provided at the upper and lower ends of the steering column, respectively.

[0008] Preferably, one end of the base plate is connected to the load-bearing plate by a hinge, the load-bearing plate has a first positioning groove and a second positioning groove on its underside, and the load-bearing plate has a plurality of positioning holes distributed along the first positioning groove and the second positioning groove inside.

[0009] Preferably, the first support rod has a U-shaped structure, with a rotating shaft at one end and a first slider at the other end. The rotating shaft is connected to the bearing of the front fixed plate, and the first slider is located inside the first positioning groove.

[0010] Preferably, one end of the second support rod is connected to the bearing of the rear fixed plate, and the other end of the second support rod is provided with a second slider, which is located inside the second positioning groove.

[0011] Preferably, the base plate is connected to the first slider by means of a positioning screw passing through a positioning hole and inside the first slider, and the base plate is connected to the second slider by means of a positioning screw passing through a positioning hole and inside the second slider.

[0012] Preferably, the sleeve is shaft-connected to the limiting plate, and an external protrusion is provided on the side of the sleeve, which is connected to the limiting plate by a pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a recessed space in the center of the base, allowing the seat plate to be stored within it. When the seat plate is needed, it is first raised to a suitable height along with the support plate. Then, the seat plate is lifted off the support plate, and the support plate is connected to the first and second sliders using positioning screws. At this point, the positions of the first and second support rods are fixed, thus fixing the positions of the seat plate and the support plate. Compared to the traditional method of mounting the seat plate on the steering column for height adjustment, this invention avoids the limitation imposed by the steering column's structure on the height the seat plate can be raised, thereby increasing the range of height that the seat plate can be raised. This improves the matching degree between the seat plate height and the child's height after adjustment, enhancing the comfort of using the scooter. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this utility model, an adjustable seat children's scooter includes a base 1 and a seat 2. A recessed space is provided in the middle of the base 1, and the seat 2 is housed inside the recessed space. A load-bearing plate 3 is provided below the seat 2, and a first support rod 5 and a second support rod 6 are provided below the load-bearing plate 3. A rear fixing plate 101 and a front fixing plate 102 are respectively provided at both ends of the base 1. A rear wheel 1011 is provided on one side of the rear fixing plate 101, and a limit plate 103 is provided on one side of the front fixing plate 102. A sleeve 402 is provided between the two limit plates 103. A directional column 4 is provided inside the sleeve 402 and is connected to the sleeve 402 by a bearing. A handlebar 401 and a front wheel 403 are respectively provided at the upper and lower ends of the directional column 4.

[0024] Example 1: Please refer to Figure 1-4 In this embodiment of the utility model, a children's scooter with an adjustable seat is provided. The seat 2 is connected to one end of the load-bearing plate 3 by a hinge 201. The load-bearing plate 3 is provided with a first positioning groove 303 and a second positioning groove 304 on its underside. The load-bearing plate 3 is provided with a plurality of positioning holes 301 distributed along the first positioning groove 303 and the second positioning groove 304. The distance between adjacent positioning holes 301 can be arbitrarily set according to the usage scenario.

[0025] The first support rod 5 has a U-shaped structure. One end of the first support rod 5 is provided with a rotating shaft 501, and the other end of the first support rod 5 is provided with a first slider 502. The rotating shaft 501 is connected to the front fixed plate 102 by a bearing. The first slider 502 is located inside the first positioning groove 303. One end of the second support rod 6 is connected to the rear fixed plate 101 by a bearing. The other end of the second support rod 6 is provided with a second slider 601, which is located inside the second positioning groove 304. The seat plate 2 is connected to the first slider 502 by a positioning screw 302 passing through the positioning hole 301 and the interior of the first slider 502. The seat plate 2 is also connected to the second slider 601 by a positioning screw 302 passing through the positioning hole 301 and the interior of the second slider 601.

[0026] When the skateboard is not in use, the seat 2 can be stored inside the recessed space. When the skateboard needs to be used, first raise the seat 2 and the load-bearing plate 3 to a suitable height, then lift the seat 2 off the load-bearing plate 3, and connect the load-bearing plate 3 to the first slider 502 and the second slider 601 through the positioning screw 302. At this time, the positions of the first support rod 5 and the second support rod 6 are fixed, thus fixing the positions of the seat 2 and the load-bearing plate 3. Compared with the traditional method of installing the seat 2 on the steering column 4 for height adjustment, this avoids the limitation of the steering column 4's own structure on the height that the seat 2 can be raised, thereby increasing the height range of the seat 2. This improves the matching degree between the height of the seat 2 and the child's height after height adjustment, and improves the comfort of using the skateboard. At the same time, since the seat 2 is not connected to the steering column 4, the pressure of the child's weight can be evenly distributed on the base 1 when the child sits on the seat 2, avoiding excessive force on the steering column 4 in some areas, reducing the risk of the steering column 4 breaking, and improving the service life of the skateboard.

[0027] Example 2: Please refer to Figure 1-4 The difference from Embodiment 1 is that the sleeve 402 is axially connected to the limiting plate 103, and the side of the sleeve 402 is provided with an outer protrusion 4021, which is connected to the limiting plate 103 by a pin 104.

[0028] After rotating the steering column 4 to the vertical position, insert the pin 104 into the interior of the limiting plate 103 and the outer protrusion 4021 to fix the position of the steering column 4. At this time, the skateboard can be used normally. When the seat plate 2 is stored in the recessed space, pull out the pin 104 and rotate the steering column 4 to the horizontal position. At this time, the skateboard becomes folded, which reduces the space required for storing the skateboard and improves the convenience of the skateboard.

[0029] The working principle of this utility model is as follows: by installing the seat plate 2 on the load-bearing plate 3, after raising the seat plate 2 and the load-bearing plate 3 to a suitable height, the load-bearing plate 3 is connected to the first slider 502 and the second slider 601 by the positioning screw 302. At this time, the positions of the first support rod 5 and the second support rod 6 are fixed, so that the positions of the seat plate 2 and the load-bearing plate 3 are fixed, thereby increasing the height range of the seat plate 2, and thus improving the matching degree between the height of the seat plate 2 and the height of the child after the height adjustment, and improving the comfort of using the skateboard.
