Detailed Description
Please refer to FIG. 1 to FIG. 4. FIG. 1 is a schematic diagram of a non-pneumatic tire 100 according to a first embodiment of the present invention. FIG. 2 is an exploded diagram of the non-pneumatic tire 100 according to the first embodiment of the present invention. FIG. 3 is a sectional diagram of the non-pneumatic tire 100 according to the first embodiment of the present invention. FIG. 4 is an enlarged diagram of an A portion of the non-pneumatic tire 100 shown in FIG. 3 according to the first embodiment of the present invention. The non-pneumatic tire 100 includes a tire casing 10, an inner tube 20, and a rim 30. The inner tube 20 is installed on the rim 30. The tire casing 10 covers the inner tube 20, such that the inner tube 20 is located between the rim 30 and the tire casing 10, as shown in FIG. 3 and FIG. 4.
Please refer to FIG. 1 to FIG. 6. FIG. 5 is a structural diagram of the tire casing 10 of the non-pneumatic tire 100 according the first embodiment of the present invention. FIG. 6 is an enlarged diagram of a B portion of the tire casing of the non-pneumatic tire 100 shown in FIG. 5 according to the first embodiment of the present invention. In the first embodiment, a cord fabric layer 40 is disposed on a surface 11 of the tire casing 10, and the surface 11 of the tire casing includes an exterior surface 111 and an interior surface 112. The cord fabric layer 40 partially covers the interior surface 112 of the tire casing 10 along the tire casing 10.
Furthermore, as shown in FIG. 3 and FIG. 4, the cord fabric layer 40 is disposed between the tire casing 10 and the inner tube 20, and the cord fabric layer 40 partially covers the interior surface 112 of the tire casing 10 along a radial direction of the tire casing 10, i.e., in the sectional view of the non-pneumatic tire 100, the cord fabric layer 40 partially covers the interior surface 112 of the tire casing along a circumferential direction of the tire casing 10.
Specifically, in this embodiment, the cord fabric layer 40 is located on at least one side of the interior surface 112 of the tire casing 10. Preferably, an end of the cord fabric layer 40 is connected to the other end of the cord fabric layer 40, so as to form an enclosed ring structure along a peripheral direction of the tire casing 10, which enhances a capability of the cord fabric layer 40 to endure loads. However, the cord fabric layer 40 also can be located at a left lateral side and a right lateral side, i.e., two lateral sides, of the interior surface 112 of the tire casing 10, such that a top side of the tire casing 10 is not too hard. Therefore, the non-pneumatic tire 100 of the present invention is more similar to a pneumatic tire. In other embodiment, the cord fabric layer 40 can be shaped in another structure instead of the enclosed ring structure. For example, the cord fabric layer 40 can be spaced on two lateral sides of the interior surface 112 of the tire casing 10 at intervals for increasing a hardness of two lateral sides of the non-pneumatic tire 100.
That is, the structure of the cord fabric layer 40 is not limited to the aforementioned embodiment.
Furthermore, in this embodiment, the tire casing 10 includes a rotating portion 101, two abutting portions 102, and two embedding portions 103. The rotating portion 101 rotatably contacts with a ground. Ends of the two abutting portion 102 are respectively connected to the rotating portion 101, and the other ends of the two abutting portion 102 respectively extend toward and abut against the rim 30.
Specifically, as shown in FIG. 4, the other ends of the two abutting portion 102 respectively extends toward and abut against the rim 30, and extend toward each other along the rim 30. The two embedding portions 103 are respectively connected to the two abutting portions 102 and respectively extend toward a center of the tire casing 10 for embedding into the rim 30, such that the tire casing 10 can be firmly installed on the rim 30. When the tire casing 10 is divided into the rotating portion 101, the two abutting portions 102, and the two embedding portions 103, the cord fabric layer 40 can completely cover an interior surface of the two embedding portions 103 and partially cover an interior surface of the two abutting portions 102, as shown in FIG. 3 and FIG. 4, i.e., the cord fabric layer 40 is not disposed on a position of the two abutting portions 102 near the rotating portion 101, so as to easily assembly the inner tube 20 within the tire casing 10. However, the configuration of the cord fabric layer 40 is not limited to the aforementioned embodiment. For example, the cord fabric layer 40 can completely cover the interior surface 112 of the two embedding portions 103 and the two abutting portions 102 and further partially cover the interior surface 112 of the rotating portion 101, or the cord fabric layer 40 can partially cover the interior surface 112 of the two errbedding portions 103 and the two abutting portions 102.
Please refer to FIG. 7 and FIG. 8. FIG. 7 is a structural diagram of the tire casing 10 of a non-pneumatic tire 200 according a second embodiment of the present invention. FIG. 8 is an enlarged diagram of a C portion of the tire casing of the non-pneumatic tire 200 shown in FIG. 7 according to the second embodiment of the present invention. Structure of the non-pneumatic tire 200 of the second embodiment is similar to structure of the non-pneumatic tire 100 of the first embodiment, and the difference between the first embodiment and the second embodiment is a location on the tire casing where the cord fabric layer 40 is disposed. Specifically, in the second embodiment, the cord fabric layer 40 is not only located at the left lateral side and the right lateral side of the interior surface 112 of the tire casing 10, but also partially covers a middle portion of the interior surface 112 of the tire casing 10. In the first embodiment, the cord fabric layer 40 is only located at the left lateral side and the right lateral side of the interior surface 112 of the tire casing 10. Except for the aforemenrioned difference, the other structure of the non-pneumatic tire 200 of the second embodiment is same as the other structure of the non-pneumatic tire 100 of the first embodiment. The detailed description is omitted herein.
In summary, in the present invention, since the cord fabric layer partially covers the interior surface of the tire casing, it reduces the overall hardness and enhances flexibility of the non-pneumatic tire of the present invention and maintains the capability of enduring loads applied on the tire casing, such that the functional property of the non-pneumatic tire of the present invention is more similar to the functional property of the pneumatic tire. Therefore, the non-pneumatic tire of the present invention has a better effect of imitating the pneumatic tire and can be adapted for cars, motorcycles, bicycles, infant carriers, luggage carriers, and so on.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
