Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an elastic temple. Background Technology

[0002] In the eyewear industry, the design of the temples plays a crucial role in wearing comfort, stability, and product durability. As people's demands for the eyewear experience continue to increase, flexible temples have received more and more attention because they can better adapt to different wearers' head shapes and activity needs.

[0003] In the prior art, there are various solutions for achieving the elastic function of eyeglass temples. For example, patent publication number CN20515899 U discloses a single-core internally positioned elastic temple. (Reference) Figure 1 As shown, the elasticity of the temples relies on a spring shell and spring structure. In practical use, this structure provides elastic deformation of the temples through the expansion and contraction of the springs to adapt to different sizes and shapes of the wearer's head. However, this structure has some obvious shortcomings. Its overall structure is relatively complex, and the combination of numerous components not only increases the assembly difficulty in the manufacturing process, reducing production efficiency, but also requires high precision in the manufacturing process. Errors in the processing of any component can affect the elastic performance and stability of the entire temple. At the same time, the complex structure means higher costs for component procurement and inventory management. From a product reliability perspective, the connection and coordinated operation of multiple components increases the probability of failure. Once a component is damaged, repair and replacement are more difficult, which undoubtedly reduces the overall durability of the product and increases the user's cost and inconvenience. Utility Model Content

[0004] In view of the problems pointed out in the background art, this utility model proposes a simple elastic temple for eyeglasses to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An elastic temple includes a post and a temple. One end of the post is provided with a hinge portion that is hinged to the temple. The temple also includes an L-shaped spring piece, which includes a fixing piece and a deformation piece. The fixing piece is fixedly connected to one end of the post and has a hole for the hinge portion to pass through.

[0007] The present invention is further configured such that the fixing plate is welded and fixed to one end of the pile head.

[0008] The present invention is further provided that the deformable sheet is provided with a C-shaped clamping part facing the opening of the temple of the eyeglasses.

[0009] The present invention is further configured such that the pile head has an L-shaped structure.

[0010] The present invention is further configured such that there are two hinge parts arranged at intervals, one end of the temple of the eyeglasses is connected between the two hinge parts, and it also includes a hinge hole that passes through the two hinge parts and the temple of the eyeglasses, and the hinge hole is connected to a hinge shaft.

[0011] The present invention is further provided that the deformable sheet is provided with a magnet that can magnetically fix the temple of the eyeglasses.

[0012] The present invention is further configured such that the length of the deformable sheet is 2-3 cm.

[0013] The present invention is further configured such that the shape of the fixing plate corresponds to and is adapted to the shape of the end face of one end of the pile head.

[0014] The present invention is further configured such that the cross-section of the deformable sheet is U-shaped.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0016] The elastic temples provided by this invention utilize a simple L-shaped spring to assist in achieving the elastic function of the temples. When the temples are opened, the spring abuts against the spring, limiting the opening angle. To further open the temples, additional force can be applied, causing the temples to rotate outwards. This forces the spring to elastically deform outwards, thus achieving elastic adjustment of the temples. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] For reference as follows Figures 1-5 The present invention will be described as follows:

[0027] Example: A flexible temple includes a head 1 and a temple 2. The head 1 has an L-shaped structure, with one end rotatably connected to the temple 2 and the other end connected to the eyeglass frame. The head 1 serves as the connecting hub between the temple and the eyeglass frame.

[0028] One end of the pile head 1 is provided with a hinge part 3 that is hinged to the temple of the eyeglasses 2, and the temple of the eyeglasses 2 is rotatably connected to the hinge part 3.

[0029] It also includes an L-shaped spring, which includes a fixing piece 41 and a deformation piece 42. The fixing piece 41 is fixedly connected to one end of the pile head 1, and the fixing piece 41 is provided with a hole 43 for the hinge part 3 to pass through. This hole is used to allow the hinge part 3 to pass through, which ensures that the hinge function between the pile head 1 and the temple 2 is not affected, and also realizes the stable assembly of the spring and the pile head 1.

[0030] When the temple 2 is in the open position, it contacts and abuts against the deformation plate 42. At this time, the deformation plate 42 physically limits the opening angle of the temple 2, preventing it from opening excessively. If it is necessary to further increase the opening angle of the temple 2, an outward rotational force is applied to the temple 2. Under this external force, the temple 2 overcomes the initial limiting force of the deformation plate 42, forcing the deformation plate 42 to elastically deform outward. As the deformation plate 42 elastically deforms, the temple 2 can continue to rotate outward, achieving dynamic adjustment of the opening angle. When the external force is removed, the deformation plate 42, relying on its own elastic restoring force, drives the temple 2 back to the initial limited angle, completing the cyclic process of elastic adjustment.

[0031] Compared to traditional temples that rely on complex structures like spring shells and springs for elasticity, this design uses a simple L-shaped spring. This design reduces the number of parts, lowers assembly complexity, and eliminates the need for precise assembly of multiple small parts during production, effectively improving production efficiency and reducing costs. Simultaneously, the single spring structure reduces potential points of failure, lowers the probability of repairs due to component damage, and enhances the overall reliability and durability of the temples, providing users with a more stable user experience.

[0032] The fixing plate 41 is welded to one end of the post head 1. This connection method has high stability and can ensure that the fixing plate 41 and the post head 1 remain relatively fixed during the frequent opening and closing of the temple, so that the elastic function of the spring can be stably performed.

[0033] Alternatively, the fixing piece 41 can be detachably connected to the post 1. Common implementation methods include snap-fit ​​connections and screw connections. Detachable connections improve the ease of product maintenance and the replaceability of parts, extend the overall service life of the temples, and also facilitate product recycling and environmentally friendly disposal.

[0034] The shape of the fixing plate 41 corresponds to the shape of the end face of one end of the post head 1. For example, if the end face of one end of the post head 1 is rectangular, the fixing plate 41 is also designed as a rectangular structure. The larger contact area helps to improve the connection strength, so that when the fixing plate 41 is subjected to the stress generated by the deformation of the spring sheet, it can transmit the force to the post head 1 more evenly and avoid local stress concentration. On the other hand, the close fit structure can reduce the assembly error caused by shape mismatch, ensure the relative position accuracy of each component of the temple, and ensure the smooth opening and closing of the temple.

[0035] Two hinge parts 3 are provided and spaced apart. One end of the temple 2 is connected between the two hinge parts 3. The frame also includes a hinge hole 6 that passes through the two hinge parts 3 and the temple 2, and a hinge shaft is connected to the hinge hole 6. The arrangement of the two hinge parts 3 forms a stable support structure, which can better constrain the rotation direction of the temple 2 compared to a single hinge point, and reduce swaying and offset during rotation.

[0036] The deformable sheet 42 of this application provides the following three implementation structures:

[0037] Structure 1: The deformable piece 42 has a C-shaped clamping part 51 facing the opening of the temple 2 (the clamping part 51 can clamp and fix the temple 2). This structure utilizes the elastic deformation characteristics of the C-shape to fix the temple 2. The opening design of the C-shaped clamping part 51 gives it a certain opening and closing capacity. When the temple 2 is opened to contact the deformable piece 42, it can be directly inserted into the opening of the C-shaped clamping part 51. As the temple 2 is inserted deeper, the C-shaped structure undergoes elastic deformation due to compression, and the inner wall forms a ring-like clamping force on the temple 2, thereby achieving a stable connection. This fixing method does not require additional connectors; assembly can be completed by relying on the elasticity of the structure itself, making it simple to operate and reliable in connection. In actual use, the C-shaped clamping part 51 can effectively limit the shaking of the temple 2 and maintain its stability in the open state; at the same time, when it is necessary to adjust the angle of the temple 2, applying an appropriate external force can overcome the clamping force and allow the temple 2 to disengage from the clamping part 51, meeting different wearing needs and combining convenience and flexibility.

[0038] Implementation Structure Two: The deformable piece 42 is equipped with a magnet 52 that can magnetically fix the temple of the eyeglasses. With this configuration, the open temple of the eyeglasses 2 can be fixedly connected to the deformable piece 42 through the magnet 52.

[0039] A magnetic connection is used to securely attach the eyeglass temple 2. The magnet 52 can be made of a strongly magnetic material, such as a neodymium iron boron magnet, and is fixed to the deformable element 42 through methods such as embedding, gluing, or injection molding. When the eyeglass temple 2 is opened and approaches the deformable element 42, the magnetic field generated by the magnet 52 attracts the eyeglass temple 2 (if the eyeglass temple 2 is made of a magnetizable metal or has built-in magnetic components), thus fixing it in place. This magnetic fixation method features quick installation and easy disassembly, allowing for connection and separation of the eyeglass temple 2 and the deformable element 42 without complex operations. During use, the magnetic force continuously maintains the stable position of the eyeglass temple 2, preventing angular displacement due to accidental collisions. Simultaneously, the magnetic connection does not create excessive resistance to the rotation of the eyeglass temple 2, ensuring smooth opening and closing. Furthermore, the magnet 52's magnetism is durable and stable, not easily affected by the daily usage environment, and can maintain a good fixing effect over a long period.

[0040] Implementation Structure 3: The cross-section of the deformation plate 42 is U-shaped. With this configuration, the opened temple 2 enters the interior of the U-shaped deformation plate 42, and the U-shape can form a constraint and limit on the temple 2.

[0041] The U-shaped structure provides physical space constraint for the temple 2, effectively limiting its movement. The two side walls and bottom of the U-shape form a semi-enclosed space, allowing the temple 2 to naturally enter the interior of the U-shaped deformation plate 42 when opened. The side walls of the U-shape restrict the movement of the temple 2, limiting its movement in three dimensions. This simple design relies on geometry for its limiting function, requiring no additional components. In practical applications, the U-shaped deformation plate 42 provides stable support for the temple 2, effectively reducing its wobbling during use. Simultaneously, due to the U-shaped structure's elastic deformation capability, the deformation plate 42 can deform appropriately to cushion pressure when the temple 2 is subjected to external force, preventing damage from hard impacts. This ensures effective limiting while improving the temple's durability and wearing comfort.

[0042] The length of the deformable piece 42 is 2-3 cm.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
