Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The scooter for children generally has pedals, front wheels and rear wheels, wherein most of the front wheels are of a double-wheel structure, are linked with a handle, can be used for steering, and the rear wheels are single wheels and are directional wheels. In the scooter fast travel process, the scooter easily falls down, and in order to improve the security, some scooters can be equipped with auxiliary wheel device.

Referring to fig. 1 to 4, in an embodiment of the present application, the auxiliary wheel device includes a mounting bracket 2, an auxiliary wheel 1, and a support portion 21 for connecting a pedal is provided on the mounting bracket 2. The generally pedal-shaped, fixed, auxiliary wheel assembly mounting locations are also relatively fixed, resulting in an auxiliary wheel assembly that can only be fitted to one scooter, with waste in design and manufacture.

To solve this technical problem, a detachable pad 22 is provided on the support portion 21 of the present application. The cushion block 22 is connected with the mounting bracket 2 in a detachable mode, so that the mounting bracket has the advantages of convenience in detachment and replaceability. Therefore, the cushion block 22 can be replaced, and the auxiliary wheel device in the application is adapted to scooters of different styles by changing the shape of the cushion block 22, so that the effect of reducing the production cost is achieved. Meanwhile, after the scooter is replaced, consumers only need to purchase corresponding cushion blocks for replacement, so that new auxiliary wheels are prevented from being purchased for adaptation.

Further, the supporting portion 21 is provided with the positioning groove 211, the positioning groove 211 plays a role in guiding the installation of the cushion block 22 on the supporting portion 21, in the process that the cushion block 22 is connected to the supporting portion 21, the cushion block 22 can be firstly attached to the bottom surface of the positioning groove 211, and then the cushion block 22 is installed in place when being pushed to be attached to the groove wall of the positioning groove 211 along the bottom surface of the positioning groove 211, so that the effect of quick positioning is achieved.

Further, the positioning groove 211 is opened at one side, and the pad 22 can enter from the opened side of the positioning groove 211 and then be pushed to be attached to the groove wall of the positioning groove 211. And a step surface can be arranged on the surface of the cushion block 22, which is attached to the groove wall of the positioning groove 211, and is adapted to the groove wall of the positioning groove 211, wherein the step surface can be divided into an upper end which extends out relatively and a lower end which retracts relatively, after the cushion block 22 is attached to the groove wall, the lower end of the step surface is attached to the groove wall, and the upper end of the step surface is engaged with the upper edge of the groove wall to complete positioning.

Further, a fastening structure is provided between the spacer 22 and the supporting portion 21, and the fastening structure can limit the movement direction of the spacer 22 along the bottom surface in the positioning groove 211. Preferably, the buckling structure comprises a buckle 3 arranged on the cushion block and a buckling hole 4 arranged on the bottom surface of the positioning groove, wherein the buckle 3 penetrates through one side of the buckling hole 4 after the cushion block 22 is installed and is buckled with the other side of the buckling hole 4, so that the cushion block is prevented from falling off from the positioning groove.

Further, a positioning structure is disposed between the spacer 22 and the groove wall of the positioning groove 211, and preferably, the positioning structure includes a positioning block 5 disposed on the spacer and a positioning hole 6 disposed on the groove wall. When the cushion block 22 is connected with the positioning groove 211, the cushion block 22 can be pushed to extend the positioning block 5 into the positioning hole 6, so as to play a role of pre-positioning. And meanwhile, after the cushion block 22 is installed, the cushion block is limited in the movement direction along the groove wall of the positioning groove, so that the cushion block is prevented from falling off along the groove wall of the positioning groove.

Further, the supporting part 21 is connected with the bottom surface of the pedal, the supporting part 21 sinks to form a recess for accommodating the pedal, the covering property of the supporting part 21 to the pedal can be increased at the recess, the contact area of the supporting part 21 and the pedal is increased, and the connection stability of the supporting part and the pedal is improved. Meanwhile, a through hole 7 is formed, and the rear wheel of the scooter passes through the through hole 7 and contacts with the ground.

Further, the support 21 has perforations 7 through which the fasteners pass, the fasteners passing through the perforations 7 to connect the support 21 to the pedal, creating a more secure connection between the auxiliary wheel device and the child walker.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
