Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] In this embodiment, refer to Figure 1 ~ Figure 3 , a hinge device with increased folding life, comprising a bar-shaped front headband (1) and a rear headband (2) hinged at the end of the front headband (1) using a hinge structure, the hinge structure includes fixing the cover with a shrapnel (6) Fasten and fix the U-shaped hinge bracket (3) at the end of the front headband (1) and the shrapnel fixing block (5) that is located at the front end of the rear headband (2) and integrally formed with the rear headband (2) ), the shrapnel fixing block (5) is made of elastic plastic material, the U-shaped opening of the U-shaped hinge bracket (3) is made of hard metal and deformable hinge shrapnel (4), and the hinge shrapnel (4) It is arranged symmetrically and tilted inward at the same time. There is also a protrusion on the inner su...

Abstract

The invention discloses a hinge device capable of prolonging folding service life, and belongs to the field of earphones. The hinge device comprises a strip-shaped front section head belt and a rear section head belt hinged with the tail end of the front section head belt through a hinge structure which comprises a U-shaped hinge support and an elastic piece fixing block, wherein the U-shaped hinge support is fixed at the tail end of the front section head belt through an elastic piece fixing cover in a covering mode, and the elastic piece fixing block is arranged at the front end of the rear section head belt and integrally formed with the rear section head belt. A U-shaped opening of the U-shaped hinge support is formed by a deformable hinge elastic piece made of hard metal. Compared with a traditional hinge device, the length of the hinge elastic piece can be freely adjusted according to force needed by a product, more space is saved, the hinge device is made of metal materials which is matched with plastic materials to do folding motions of a hinge, folding effect of the hinge is improved, friction coefficient of the hinge can be reduced, therefore product service life can be prolonged, and the service life is more than two times of that of the traditional hinge device.

Description

technical field [0001] The invention relates to the field of earphones, in particular to an earphone hinge device, in particular to a hinge device with a longer folding life. Background technique [0002] The traditional earphone hinges with folding function wear a lot and are not durable, while most common hinge structures have "plastic to plastic" or "metal to metal", that is to say, the hinge shrapnel and the shrapnel fixing block in the hinge structure are respectively made of Made of plastic or metal materials. If both the hinge shrapnel and the shrapnel fixing block are made of the same hardness material, the wear between them will be very large and the service life will be very short. The folding life of conventional headphone hinges is less than 1,000 times. If a headphone is folded three times, its service life is less than one year. Therefore, in order to improve the service life of the product, it will be the research direction of folding earphones in the future...
