Description

Technical Field

[0001] This utility model belongs to the field of eyeglass frame technology, and specifically relates to a dual-axis elastic central beam folding module. Background Technology

[0002] With the increasing popularity of portable eyewear, especially in the fields of sunglasses, reading glasses, and smart glasses, folding glasses are favored by consumers due to their convenient storage characteristics. Existing folding eyewear technology mainly focuses on the milled chain folding structure of the temples and frame, as well as the folding structure of the bridge. Among these, the design of the folding components at the bridge directly affects the overall thickness after folding, the smoothness of the folding action, structural stability, and lifespan. Existing bridge structures generally suffer from technical problems such as easy loosening, poor stability, and excessive thickness after folding, leading to awkward use. Therefore, there is an urgent need for a new type of bridge folding module to solve these problems. Utility Model Content

[0003] The purpose of this invention is to address the technical problems of poor stability and large thickness of existing eyeglass bridge structures in the dual-axis elastic folding module.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dual-axis elastic beam folding module, comprising two arms connected to the left and right mirror frames and a folding module disposed between the two arms, wherein the folding module comprises a mounting frame and two elastic plates, the two elastic plates being mirror-stacked within the mounting frame, a stop block being provided on the rear side of the elastic plate, a first connecting block being provided on the front side, and a second connecting block being provided on the outer side, a notch being provided on the inner side of the first connecting block, the end of the arm being disposed on the notch, the arm and the elastic plate on the same side being connected by a pin, and a rotation hole being provided between the end of the two arms and the first connecting block.

[0005] Preferably, the mounting bracket has a "U" shaped structure, and a screw is provided in the middle of the mounting bracket. The screw passes through one side of the mounting bracket, two stacked elastic plates, and the other side of the mounting bracket in sequence.

[0006] Preferably, the mounting bracket is provided with a plurality of mounting holes one, and the elastic sheet is provided with a plurality of mounting holes two.

[0007] Preferably, the elastic sheet is a soft rubber pad, a double spring, or an elastic limiting member.

[0008] Preferably, the overall structure of the dual-axis elastic beam folding module is made of titanium alloy, stainless steel, or CNC aluminum.

[0009] In summary, this utility model has the following beneficial effects:

[0010] 1. By providing a bridge structure for eyeglasses that has high stability, good durability and convenient folding effect, the problems of loose structure, large thickness after folding, high processing difficulty and low safety in use in the existing technology are solved.

[0011] 2. Specifically, the folding module is configured as a mounting frame and two elastic plates, which provide damping and restoring force during folding. When installing the folding module and the support arm, the two elastic plates are first stacked and placed inside the mounting frame, then the end of the support arm is placed at the notch of the elastic plate, and finally fixed with pins and screws. This allows the support arm to fold or unfold in opposite directions within the mounting frame, achieving a dual-axis folding effect. Furthermore, the elasticity of the elastic plates provides damping and restoring force during folding, preventing the support arm from loosening and ensuring good stability of the center beam.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, the dual-axis elastic central beam folding module of this utility model includes two arms 1 connected to the left and right mirror frames and a folding module 2 disposed between the two arms. The folding module 2 includes a mounting frame 21 and two elastic plates 22. The two elastic plates 22 are mirror-stacked in the mounting frame 21. A stop block 221 is provided on the rear side of the elastic plate 22, a first connecting block 222 is provided on the front side, and a second connecting block 223 is provided on the outer side. A notch 224 is provided on the inner side of the first connecting block 222. The end of the arm 1 is disposed on the notch 224. The arm 1 and the elastic plate 22 on the same side are connected by a pin 23. A rotating hole is provided between the end of the two arms 1 and the first connecting block 222.

[0018] This utility model discloses a dual-axis elastic beam folding module, comprising two arms 1 and a folding module 2. The folding module 2 is disposed between the two arms 1, allowing the two arms 1 to fold inward for storage. The folding module 2 includes a mounting frame 21 and two elastic plates 22. The two elastic plates 22 have identical structures, are stacked inside the mounting frame 21, and are connected to the arms 1 via pins 23. Specifically, the elastic plate 22 includes interconnected stops 221, a first connecting block 222, and a second connecting block 223. The stops 221 have a strip-shaped structure and are disposed on the inner side of the mounting frame 21. The first connecting block 222 and the second connecting block 223 are block-shaped structures and are set on the outside of the mounting frame 21. During assembly, the two elastic sheets 22 are first stacked, then the elastic sheets are placed inside the mounting frame 21, and then the ends of the two support arms 1 are placed at the notch 224. Finally, the pins 23 are inserted into the mounting frame 21, the elastic sheets 22 and the support arms 1, so that the support arms 1 are connected to both ends of the folding module 2. By leaving a rotation hole between the end of the support arm 1 and the first connecting block 222, the rotation space is reserved when the support arm rotates, so that the support arms 1 can be folded or unfolded in opposite directions.

[0019] In a preferred embodiment, refer to Figure 1 and Figure 2 The mounting bracket 21 has a U-shaped structure, with a screw 211 in the middle. The screw 211 passes through one side of the mounting bracket, two stacked elastic plates, and the other side of the mounting bracket. The mounting bracket 21 has multiple mounting holes 213, and the elastic plates 22 have multiple mounting holes 225. The elastic plates 22 are soft rubber pads, double springs, or elastic limiting components.

[0020] Specifically, the mounting bracket 21 has a U-shaped structure, with a mounting groove 212 in the middle for mounting the elastic plate 22. Additionally, the lower support plate of the mounting bracket 21 has locking grooves at both ends to support the positioning of the support arm 1 when it is extended, preventing the support arm from becoming loose. A screw 211 is located in the middle of the mounting bracket 21, passing through the mounting bracket 21 and the elastic plate 22, allowing the elastic plate to be stably mounted on the mounting bracket 21. By providing mounting holes 213 on the mounting bracket 21 and multiple mounting holes 225 on the elastic plate 22, the pin 23 passes through the mounting bracket 21, the elastic plate 22, and the support arm 1, ensuring that the support arm 1 can rotate within the mounting bracket 21.

[0021] The overall structure of this dual-axis elastic beam folding module is made of titanium alloy, stainless steel, or CNC aluminum, ensuring that the folding module is strong, lightweight, and has a long service life.

[0022] The biaxial elastic central beam folding module of this utility model has the following characteristics:

[0023] 1. Stable structure: The design of symmetrical double rotating shafts with elastic pressure components effectively prevents loosening and shaking;

[0024] 2. Smooth folding: The two arms can be folded inwards in parallel, significantly reducing the overall thickness after folding;

[0025] 3. Modular manufacturing: The central structure adopts a modular production design, which facilitates CNC machining and molded mass production;

[0026] 4. Excellent user experience: Smooth opening and closing, moderate damping, effectively preventing finger pinching, suitable for smart glasses and hidden designs;

[0027] 5. High durability: The core load-bearing components are made of metal materials and have a precision structural design, which can withstand a large number of opening and closing cycles;

[0028] 6. Ultra-thin design: The arm can be completely folded into the back of the lens, achieving an ultra-thin folding effect.

[0029] In actual manufacturing, this invention, through precise grouping, screw installation, and spinning processes, enables repeated use and stable folding in the middle of different types of eyeglasses. The main module adopts a small-sized, high-layer hollow assembly, ensuring both elasticity and folding feel, making it suitable for portable smart glasses or ultra-thin glasses.
