Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart eyeglass temple technology, specifically to a smart eyeglass temple with adjustable length. Background Technology
[0002] With the development of smart wearable devices, smart glasses often integrate electronic components such as microphones, speakers, and batteries into their temples. To ensure stable installation of these internal components, traditional glasses and current mainstream smart glasses typically use fixed-length temple tips, ear loops, or smart devices. However, different users have different head shapes, such as varying face widths, ear heights, horizontal distances from the brow point to the ear attachment point, and temple bend lengths. Fixed-length temples cannot adapt to diverse head shapes with a single piece, easily leading to loosening, slippage, or pressure on the ears. Furthermore, the speaker outlet of smart glasses needs to be located before the temple bend and aligned with the ear at a 45-degree angle. Temples that are too long or too short will directly cause displacement of the sound outlet, severely affecting the stability of the sound quality function.
[0003] To improve adaptability, some solutions involve changing the length of the temples, temple tips, or eyelets, or using frames with different face widths for adjustment. However, these solutions have limited adjustment range and struggle to balance structural strength, aesthetics, and cost control. Other adjustable temples employ threaded or spring-pin adjustment structures, such as the patent application number 202323184791.1, "An Adjustable Temple and Smart Glasses," which uses a spring and positioning pin to form a locking structure. This not only makes adjustment cumbersome but also leads to decreased accuracy due to structural wear after repeated adjustments. Furthermore, the assembly process is complex and costly. Additionally, whether fixed-length or traditional adjustable temples, they are mostly fixedly connected to the frame. When the temples are damaged or different functional modules need to be replaced, the entire frame must be replaced, resulting in high maintenance costs and insufficient flexibility. Utility Model Content
[0004] The purpose of this invention is to provide an intelligent eyeglass temple with adjustable length to solve the above-mentioned problems, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This utility model provides an adjustable-length smart glasses temple, including a post, a smart temple body, and a telescopic component for connecting the post and the smart temple body. The telescopic component can adjust the distance between the post and the smart temple body.
[0007] The telescopic component includes a spring piece that is fixedly connected to the smart temple body and is installed inside the post head in a plug-in manner;
[0008] Multiple positioning grooves are equidistantly arranged inside the pile head along its own length direction. The spring piece is provided with a protrusion that can match the positioning groove. The protrusion is used to cooperate with the positioning groove to adjust the installation position of the spring piece inside the pile head.
[0009] The above-mentioned adjustable-length smart temples have a hinged ear plate that is rotatably connected to the eyeglass frame. The smart temple body is inserted into the hinged ear plate through a telescopic component, which can be directly inserted and removed. Different temples can be matched with different frames through the telescopic component.
[0010] By stretching or contracting the telescopic components, the distance between the smart temple body and the head can be adjusted, so that the ear bend of the smart temple body can be accurately fitted to the wearer's ear.
[0011] The telescopic component engages with the protrusion through the positioning groove, and utilizes the deformation properties of the spring to maintain the stability of the current length while facilitating length adjustment.
[0012] Preferably, the pile head has a cavity that communicates with the positioning groove.
[0013] Preferably, the telescopic component includes a connecting post fixedly installed inside the smart temple body, the connecting post being fixedly connected to a spring piece, the spring piece protruding from the surface of the connecting post, and both the connecting post and the spring piece being clearance-fitted with the inner wall of the cavity.
[0014] Preferably, the connecting post has a mounting groove inside, with both sides of the mounting groove extending radially through the connecting post. The spring piece is disposed within the mounting groove and has a clearance fit with the mounting groove. The connecting post has screw holes with screws threaded into them for fixing the connecting post and the spring piece together.
[0015] And the screw does not protrude from the screw hole.
[0016] Preferably, a guide block is fixedly connected to the surface of the connecting column, and the guide block has a groove.
[0017] Preferably, the smart temple body is provided with a mounting cavity that fits with the connecting post, guide block and groove. The part of the connecting post located in the mounting cavity is provided with a positioning hole, and a positioning hole that is inserted into the positioning hole is fixedly connected in the mounting cavity.
[0018] Preferably, a hinged lug is fixedly connected to the pile head.
[0019] Preferably, the spring sheet has a strip-shaped notch along the length of the cavity, and the strip-shaped notch penetrates one side of the spring sheet. The strip-shaped notch divides the spring sheet into a fixed area and a deformation area, and a protrusion is provided on the deformation area.
[0020] Preferably, the position where the protrusion contacts the inner wall of the positioning groove is an inclined surface or an arc surface.
[0021] Preferably, a speaker outlet is provided at the junction of the ear bend of the smart temple body and the straight section of the smart temple body.
[0022] The beneficial effects are:
[0023] 1. The distance between the head and the smart temple body can be adjusted by telescopic components. Combined with the multi-positioning of positioning groove and spring protrusion, the temple length can be precisely adjusted according to the head circumference and ear shape of different users to ensure that the ear bend fits the ear contour tightly, avoids loosening or pressure, and significantly improves wearing comfort.
[0024] 2. Length adjustment is achieved through the interlocking engagement of the protrusion and the positioning groove. Only axial force is required to complete the extension and retraction, making the adjustment process smooth and effortless. It also effectively maintains the current length, preventing loosening due to vibration or impact during use and ensuring structural stability. It is flexible to assemble and disassemble, and offers excellent maintainability.
[0025] 3. The smart temple body and the head are connected by a telescopic component, which can be quickly disassembled and assembled, making it easy to replace the temple or frame separately, reducing maintenance costs. At the same time, it supports the free combination of temples and frames with different functions, improving the flexibility of product use.
[0026] 4. The beveled or arc-shaped contact design between the protrusion and the positioning groove reduces frictional resistance during adjustment and extends the service life of the structure; the cooperation between the guide block and the groove enhances connection stability; the layout of the speaker outlet and the vent hole ensures the sound quality of the audio function; the overall structure takes into account both functionality and practicality.

[0041] The deformation zone thickness of the spring piece 12 is 0.2-0.5mm, and the elastic deformation limit is not less than 3mm to ensure that the protrusion 20 can completely disengage from the positioning groove 16 to achieve gear switching;
[0042] The fatigue life of the spring 12 is no less than 5,000 cycles of reciprocating adjustment to meet the durability requirements of daily use, and the change rate of the elastic coefficient in ambient temperature of -10℃ to 60℃ does not exceed 10%, making it suitable for different use environments.
[0043] The depth and width of each positioning groove 16 are adapted to the protrusion 20, and the protrusion 20 and the positioning groove 16 form a detachable snap-fit engagement to realize multi-level length adjustment of the smart glasses temple. Multiple positioning grooves 16 are equidistantly arranged inside the post head 1 along its own length direction. The spring piece 12 is provided with a protrusion 20 that can match the positioning groove 16. The protrusion 20 is used to engage with the positioning groove 16 to adjust the installation position of the spring piece 12 inside the post head 1.
[0044] The positioning grooves 16 are equidistantly arranged along the length direction inside the pile head 1. The distance between two adjacent positioning grooves 16 is 3-5mm to ensure adjustment accuracy to adapt to the differences in different head shapes.
