This invention relates generally to a technology for a sliding shell on a slide-type mobile phone, and particularly to a sliding shell with a smooth slide and abrasion durability.
A conventional sliding shell on a slide-type mobile phone is usually composed of two plastic shells. The two plastic shells are combined by a set of guideway mechanism for being capable to slide relatively. The opposite combined surfaces of the two plastic shells are directly overlapped and contacted according to the requirement of appearance and quality of the mobile phone. Thus, there will be a certain level of friction force generated between the two plastic shells during sliding that would not only cause the sliding of the two plastic shells not smoothly, but also be liable to leave the abrasive marks on the surfaces of the two plastic shells that affects the appearance of the mobile phone.
Currently, the method for solving the large friction resistance causing not smoothly sliding is to improve the flatness of surfaces between two plastic shells, or to lay on lubricants on the guideway. However, even the above-mentioned method can reduce the friction resistance, it will still exists with the abrasive marks. While improving the flatness of surfaces between two shells, both of the unfavorable products and the cost of the products will increase accordingly.
Moreover, currently for preventing the occurrence of abrasive marks approximately have two methods: the first method is to increase the gap between two plastic shells, and the second method is to attach a protection sheet between two plastic sheets. However, the two methods will both increase the gap between two plastic shells to affect the appearance impression. Furthermore, the protection sheet applied to the second method increases the friction resistance to cause the sliding of two plastic shells further not smoothly.
The primary objective of the present invention is to provide a sliding shell with a smooth sliding and more abrasion durability. The structure of the sliding shell comprises a first shell body having a first surface, a first interface layer formed by coating a smooth material on the first surface, a first sliding assembly formed on the first surface of the first shell body, a second shell body having a second surface, and a second sliding assembly formed on the second surface of the second shell body and connected with the first sliding assembly correspondingly to allow the first shell body sliding between the first position and the second position on the second shell body. In addition, the first interface layer overlaps the second surface when the first and second shell bodies are connected as a relatively sliding status via the first and second sliding assemblies.
Thus, when the first shell body is sliding on the second shell body, the first interface layer reduces the sliding resistance and prevents the occurrence of abrasive marks, so as to have the benefits of smooth sliding and abrasion prevention.
The invention will be more clearly understood after referring to the following detailed description read in conjunction with the drawings wherein:
The first shell body 1 has a first surface 10, which has a connecting area 11 and a protrusive area 12 thereon. Furthermore, the first interface layer 2 is formed by coating a smooth material on the connecting area 11 of the first surface 10, and the smooth material is a Teflon material. In addition, the first sliding assembly 3 is formed on the first surface 10 of the first shell body 1. The second shell body 4 has a second surface 40, which has a supporting area 41 and an exposed area 42 thereon, and the exposed area 42 has a plurality of buttons (43) thereon.
Moreover, the second interface layer 5 is formed by coating a smooth material on the supporting area 41 of the second surface 40, and the smooth material is also a Teflon material. The second sliding assembly 6 is formed on the second surface 40 of the second shell body 4 and connected with the first sliding assembly 3 correspondingly, so as to allow the first shell body 1 sliding between a first position and a second position on the second shell body.
A second preferred embodiment of the present invention is shown in
Furthermore, in order to further improve the smooth sliding between the first shell body 1 and the second shell body 4, at least one of the first sliding assembly 3 and the second sliding assembly 6 is coated with the Teflon material thereon.
When the first shell body 1 is sliding on the second shell body 4, the sliding resistance to both first shell body 1 and the second shell body 4 is reduced by the first interface layer 2 and the second interface layer 5 that assist the sliding. Furthermore, the first interface layer 2 and the second interface layer 5 form protection layers for protecting the first surface 10 of the first shell body 1 and the second surface 40 of the second shell body 4 to greatly reduce the abrasive marks during sliding, because they are smooth and/or wear-resistance materials.
