One end of the first section 211 is pivotally mounted to an inner surface of the receiving opening 16 of the housing 10 away from the recessed track 15. The other end of the first section 211 is pivotally mounted to one end of the second section 212. The other end of the second section 212 is pivotally mounted to the guide 213. The guide 213 is received in and is movable along the recessed track 15 of the housing 10, and has a width W4, and a thickness T4. In the present exemplary embodiment, the bent portion 214 is elongated. The width W4 of the guide 213 is greater than the width W3 of the bent portion 214 to form a T-shaped structure.
The support member 22 is received in the receiving opening 16 of the housing 10, is pivotable relative to the first section 211 of the bending member 21, and includes two end portions. One of the end portions of the support member 22 is secured to the second section 212 of the bending member 21. The other end portion of the support member 22 is adjacent to the first section 211 of the bending member 21. In the present exemplary embodiment, the support member 22 is elongated. A length of the support member 22 is substantially equal to a length of the bent portion 214.
In the present exemplary embodiment, the housing 10 and the bending member 21 are integrally formed and connected to each other, such as by the support member 22 being embedded in the bending member 21. The housing 10 and the bending member 21 are made of an elastic material, for example, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), polypropylene, or the like. The support member 22 is made of a rigid material that is not easily bent, for example, iron, aluminum, or aluminum alloy, polycarbonate (PC), or the like.
With reference to FIG. 4, in the present exemplary embodiment, the support member 22 includes a recess 220, and a plurality of holes 221. The recess 220 is formed in the end portion of the support member 22 which is secured to the second section 212 of the bending member 21. The holes 221 are formed through the support member 22, and are defined in the recess 220. The elastic material for forming the bending member 21 is injected into the recess 220 to pass through the holes 221 such that the end portion of the support member 22 is embedded in the second section 212 of the bending member 21. In other exemplary embodiments, the end portion of the support member 22 may be secured to the second section 212 of the bending member 21 by other connectors, such as, but not limited to, screws, buckles, and cuffs.
With reference to FIG. 3, in the present exemplary embodiment, a thickness T5 of a mounting portion 215 between the base 18 and the first section 211 is less than the thickness T1 or T2 of one of the base 18 and the first section 211, a thickness T6 of a mounting portion 216 between the first section 211 and the second section 212 is less than the thickness T2 or T3 of one of the first section 211 and the second section 212, and a thickness T7 of a mounting portion 217 between the second section 212 and the guide 213 is less than the thickness T3 or T4 of one of the second section 212 and the guide 213, such that the mounting portions 215, 216, and 217 provide a mounting which can pivot, and are easily bent when force is applied thereto. In other exemplary embodiments, the bending member 21 may be made of a rigid material, and shafts or hinge pins may be mounted on the base 18, first section 211, second section 212, and guide 213.
The housing 10 further includes openings and other structures corresponding to a camera, headphone jack, and other ports. The openings and other structures are not technical features of the present disclosure.
With reference to FIGS. 1 and 2, when the support member 22 is not pulled out, the support member 22 and the bent portion 214 are received in the receiving opening 16, and the guide 213 is received in the recessed track 15 to occupy very little space. The guide 213 is located at one of the ends of the recessed track 15 away from a center of the receiving opening 16. With reference to FIGS. 5 and 6, when the support member 22 is pulled out, the bent portion 214 bends, and the guide 213 is moved to the other end of the recessed track 15 adjacent to the center of the receiving opening 16. With reference to FIG. 7, the support member 22, the base 18, and the first section 211 form an A-shaped structure when the support member 22 is pulled out. The support member 22 and housing 10 can rest on a horizontal surface (e.g., a desktop) to support the mobile device, such that the mobile device can be free-standing.
With reference to FIG. 8, an exemplary embodiment of a method for manufacturing the protective cover 1 includes the steps of: Step 51, preparing a mold having a mold cavity having the same shape as the protective cover 1; Step S2, putting the support member 22 prepared in advance in a corresponding position in the mold cavity; Step S3, injecting the elastic material for forming the housing 10 and the bent member 21 into the mold cavity; Step S4, thermoforming the elastic material in the mold cavity to form a molded protective cover; and Step S5, removing edge scrap from the molded protective cover to form the finished protective cover 1.
