JP3168325U - Filling tire for lightweight vehicle - Google Patents

Abstract

To provide a filling tire for a lightweight vehicle. The lightweight vehicle-filled tire includes a rim, a tire outer shell attached to the outer side of the rim, a hard elastic structure provided inside the tire outer shell and having one end abutting on the outer side of the rim, and the tire. A soft elastic filler that is provided inside the outer skin and that has one end abutting against the other end of the hard elastic structure is included, thereby achieving improved tire support strength and balance during rotation.

Description

  The present invention relates to a kind of filling tire for a lightweight vehicle, and more particularly to a filling tire capable of improving support strength and balance.

  So-called “lightweight vehicles” are: 1. The body weight is relatively light. 2. Loading load is relatively small. This refers to conditions that do not require charging. For example, there are bicycles, golf carts, baby carriages, shopping carts, shopping carts, wheelchairs, wheelchairs, and trolleys for suitcases.

  All known lightweight vehicle-filled tires replace the commonly used pneumatic tires by injecting elastic foam filler directly into the tire shell. However, the structural strength of the elastic filling and the filling uniformity within the tire are difficult to grasp, and uneven filling tends to occur during the internal filling, resulting in a reduction in quality.

  In addition, this traditional filled tire has only one kind of hardness, if it is too soft it cannot support the vehicle, i.e. the support strength is low, and if it is too hard, it lacks elasticity, The balance at the time of tire rotation is affected, and in any case, improvement is awaited.

  An object of the present invention is to improve a known defect by providing a lightweight vehicle-filled tire capable of improving support strength and balance.

  In order to achieve the above-described object, the present invention includes a rim, a tire skin attached to the outside of the rim, a hard elastic structure provided inside the tire skin and having one end abutting the rim, and the tire skin. Including a soft elastic filler, one end of which is in contact with the other end of the hard elastic structure, thereby achieving improved tire support strength and balance during rotation.

  A lightweight vehicle-filled tire according to the present invention includes a rim, a tire outer shell attached to the outer side of the rim, a hard elastic structure provided inside the tire outer shell and having one end abutting on the outer side of the rim, and the tire outer shell. It includes a soft elastic filler that is provided inside and has one end abutting against the other end of the hard elastic structure, thereby achieving improved tire support strength and balance during rotation.

It is a three-dimensional exploded view of the present invention. It is a three-dimensional sectional view of the present invention.

  In order to describe in detail the technical contents, structural features, and objects to be achieved of the present invention, examples will be described below in combination with the drawings.

Please refer to FIGS. The present invention
A rim 1 made of hard plastic or metal material;
A tire skin 2 formed of rubber and provided outside the rim 1;
For example, a hard elastic structure 3 formed of an elastic foam material such as EVA, TPU, TPR, provided inside the tire outer skin 2 and having one end abutting on the rim 1;
For example, a soft elastic filler 4 formed of a liquid foam material such as PU or silicon rubber, provided inside the tire outer skin 2 and having one end abutting on the other end (upper end) of the hard elastic structure 3;
Is included.

  By combining the above structures, the present invention first fills the space between the rim 1 and the tire skin 2 (that is, the inside of the tire skin 2) with the hard elastic structure 3 to support the tire skin 2, and then further Liquid foam is injected to fill the gap between the tire outer skin 2 and the rim 1 to form the soft elastic filler 4, assisting the support of the tire outer skin 2, and maintaining the roundness of the tire, In addition, it provides a certain structural strength and improves the supporting strength of the tire.

  In addition, the soft elastic filler 4 fills the gap between the rim 1 and the tire outer skin 2, prevents water or mud from entering the tire, and provides the tire with a certain elasticity. Improve balance during rotation.

  Therefore, it shows that it is far more advanced than the known technology.

  The above description is only an example of the present invention, and does not limit the scope of the present invention. Any equivalent changes and modifications that can be made based on the scope of the claims of the present invention are all described in the present invention. Shall belong to the scope covered by the rights.
