Description

Bending hinge mechanism and ear clip type earphone

Technical Field

Background Art

In recent years, with the continuous improvement of living standards, various electronic products have continuously entered people's daily lives and become an indispensable part of people's work, study and leisure. Among them, headphones are a particularly important type of electronic product. Headphones are a conversion unit that converts the electrical signals received from the self-media player into sound waves audible to the human ear through the speaker. Headphones are increasingly popular among consumers due to their high portability and small size. At the same time, consumers' demand for headphones is getting higher and higher, and consumers' expectations and requirements for headphones are also constantly increasing.

Currently, the earphones on the market generally rely on the auricle itself to clamp the earphone body to fix the wearer; or use the elasticity of the earphone material to clamp the ear to fix the wearer. Although these methods achieve the purpose of fixed wear, the first method requires the auricle muscles to be squeezed and then the earphone is tightened in the opposite direction, so the ear muscles are always squeezed and deformed, which will make it uncomfortable to wear for a long time; while the latter method uses the elastic material to retain the force and clamp the ear muscles. Some people have thicker ear muscles, while others have thinner ones. For people with thicker ear muscles, this clamping force will be greater, and the ears will be uncomfortable and even painful when worn for a long time.

In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

In one embodiment, referring to Figures 1 and 2 of the specification, a bending hinge mechanism provided by the present invention includes a fixed segment 1, a plurality of rotating segments 2, and a damping segment 3 which are rotatably connected in sequence, and the rotation angle between each adjacent segment is less than 90°. The fixed segment 1, the plurality of rotating segments 2, and the damping segment 3 are arranged in linkage, so that when the bending hinge mechanism is bent, the rotation angle between any two adjacent segments is the same, and the damping segment 3 is used to realize arbitrary positioning of the bending angle of the bending hinge mechanism.

In this embodiment, the hinge mechanism is divided into several connecting rod segments, and each of the divided segments can be rotated. The rotation angle can be designed as needed. The design value of the rotatable angle between two segments is less than 90 degrees. If the angle is too large, it will cause the outer soft rubber to be pulled and cracked or whitened during use. If the rotation angle between the two segments is a, the total rotatable angle of the 5-segment connecting rod is designed to be b, and b=4*a, such as a=35°, then b=140°; each rotating segment is in a linkage state. If the bending hinge mechanism is bent at any position, the entire bending hinge mechanism will bend continuously.

In one embodiment, with reference to Figures 3, 5 to 7 of the specification, the rotating section 2 includes: a first linkage rod 21, a second linkage rod 22, a fixed rod 23 and a rotating wheel 24. The first linkage rod 21 is provided with a first slide groove 211, the second linkage rod 22 is arranged parallel to the first linkage rod 21 and spaced apart, and the second linkage rod 22 is provided with a second slide groove. The fixed rod 23 is arranged between the first linkage rod 21 and the second linkage rod 22, and the fixed rod 23 is provided with a mounting cavity 233. The first swing rod 241 and the second swing rod 242 are respectively provided at both ends of the rotating wheel 24, and the rotating wheel 24 is adapted to be installed in the mounting cavity 233, so that the first swing rod 241 is inserted in the first slide groove 211, and the second swing rod 242 is adapted to be inserted in the second slide groove.

Specifically, referring to Figures 5 to 7 of the specification, first connecting holes 212 are respectively provided at both ends of the first linkage rod 21, the two first connecting holes 212 are provided along the length direction of the first linkage rod 21, the first slide 211 extends along the width direction of the first linkage rod 21, the two first connecting holes 212 are symmetrically arranged on both sides of the first slide 211, and first avoidance grooves 213 are provided on both sides of the first slide 211. Second connecting holes are respectively provided at both ends of the second linkage rod 22, the two second connecting holes are provided along the length direction of the second linkage rod 22, the second slide extends along the width direction of the second linkage rod 22, the two second connecting holes are symmetrically arranged on both sides of the second slide, and second avoidance grooves are provided on both sides of the second slide.

The first swing rod 241 and the second swing rod 242 are provided at opposite sides of the two ends of the rotating wheel 24.

In this embodiment, the first linkage rod 21 and the second linkage rod 22 realize motion linkage through the rotating wheel 24 in the middle of the fixed rod 23, and the motion directions are opposite. The first linkage rod 21 and the second linkage rod 22 are respectively connected to the front and rear rotating sections in rotation to form a synchronous linkage effect of each rotating section. For example, when the first linkage rod 21 slides to the left, the first swing rod 241 is driven to slide to the left through the first slide groove 211. When the first swing rod 241 slides to the left, it drives the rotating wheel 24 to rotate; because the first swing rod 241 and the second swing rod 242 on both sides of the rotating wheel 24 have a rotation angle difference of 180° around the rotation center of gravity, the second swing rod 242 can be driven to rotate in the opposite direction, and the second linkage rod 22 can be driven to slide to the right, thereby realizing the linkage of the first linkage rod 21 and the second linkage rod 22 driving the front and rear sections respectively.

In one embodiment, referring to Figures 1 to 12 of the specification, taking the case where three rotating sections 2 are provided, the one close to the fixed section 1 is called the front rotating section, the one close to the damping section 3 is called the rear rotating section, and the one between the front rotating section and the rear rotating section is called the middle rotating section.

The first linkage rod 21 and the second linkage rod 22 are connected by a rotating wheel 24. The first linkage rod 21 and the second linkage rod 22 form a completely parallel movement effect through a quadrilateral structure, so that each section of the bending hinge mechanism moves stably, each state is unique, and product precision is achieved; the first linkage rod 21 and the swing arm 25 rotatably connected at both ends form a deformable quadrilateral structure. During the movement of the first linkage rod 21, it is constrained by the swing arm 25 and can only move in parallel and stably. The structural principle of the second linkage rod 22 is the same. A boss 251 is set at one end of the swing arm 25.
