Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a battery quick-change structure and a faster battery change method. Background Technology

[0002] With the rapid development of augmented reality (AR) technology, AR glasses, as an emerging wearable smart device, are gradually being applied in various fields such as daily life, entertainment, industry, and medicine. AR glasses typically integrate multiple electronic components such as display modules, processing chips, and communication modules, which consume a significant amount of power, thus requiring energy storage modules to power them.

[0003] Currently, existing battery technologies for AR glasses on the market suffer from a series of pain points, failing to meet the core requirements of all-scenario use, lightweight design, convenience, and safety and stability. Specifically: Built-in fixed batteries suffer from short battery life, are not replaceable, and are difficult to repair, causing users to experience battery anxiety when outdoors or using them for extended periods. Removable batteries using snap-on or sliding plug-in designs are cumbersome in structure, slow to install and remove, affecting not only the wearing experience but also providing poor protection. Externally mounted, separate batteries are inconvenient to wear and severely impact the product's aesthetics. Summary of the Invention

[0004] This invention aims to address at least one of the technical problems existing in the prior art. To this end, this invention proposes a quick-swap battery structure that enables rapid battery replacement, thus alleviating range anxiety.

[0005] The present invention also proposes a quick-swap method having the above-described quick-swap battery structure.

[0006] A battery quick-swap structure according to a first aspect embodiment of the present invention includes: The temple unit includes a main body and an ear clip. The main body is used to connect to the frame, and a mounting cavity is provided at the end of the main body away from the frame. The mounting cavity is a cavity structure with one open end. An energy storage module is provided inside the ear clip. The mounting unit includes a first mounting component and a second mounting component. The first mounting component is disposed on the main body, and the second mounting component is disposed on the clamping ear. The first mounting component and the second mounting component are mutually adapted, and the clamping ear is detachably mounted on the main body. When the clip is installed on the main body, the energy storage module provides power.

[0007] According to an embodiment of the present invention, a quick-change battery structure has at least the following advantages: By providing a detachable clip and embedding the energy storage module within the clip, the user can quickly remove the clip and replace it with a pre-charged clip when the battery is depleted, without needing to connect to an external power source or wait for charging. This significantly extends the continuous use time of the AR glasses and solves the problems of short battery life and non-replaceability of built-in fixed batteries. A mounting cavity with an opening is provided at the end of the main body away from the frame, allowing the clip to be directly inserted or removed along the opening direction. The disassembly and assembly are simple and smooth, requiring no tools and achieving a rapid battery swapping experience with one-handed operation. This avoids the cumbersome and inconvenient disassembly and assembly of traditional snap-on or sliding plug-in structures. The mutual adaptation of the first and second mounting components ensures a secure connection between the clip and the main body after installation, preventing it from easily loosening. Simultaneously, the clip is fully embedded in the mounting cavity, seamlessly integrating with the shape of the temple body, maintaining the lightweight, thin, and ergonomic design of the AR glasses without affecting wearing comfort or product aesthetics.

[0008] According to some embodiments of the present invention, the first mounting component is a first magnet, the second mounting component is a second magnet, and the first magnet and the second magnet attract each other.

[0009] According to some embodiments of the present invention, the sidewall of the first magnet is provided with a first inner groove, the sidewall of the second magnet is provided with a second inner groove, the main body is integrally formed with the first magnet through the first inner groove, and the clamping ear is integrally formed with the second magnet through the second inner groove.

[0010] According to some embodiments of the present invention, the main body and the first magnet are integrally formed by injection molding, the main body is embedded in the first inner groove, the clip portion and the second magnet are integrally formed by injection molding, and the clip portion is embedded in the second inner groove.

[0011] According to some embodiments of the present invention, the clamping ear has a conductive end and a gripping end disposed opposite to each other; a guide groove is provided on the outer side wall of the conductive end, and a guide protrusion is correspondingly provided on the inner side wall of the mounting cavity; Alternatively, the outer wall of the conductive end is provided with a guide protrusion, and the inner wall of the mounting cavity is provided with a corresponding guide groove; the guide groove and the guide protrusion are adapted to each other to restrict the clamping ear from being inserted into the mounting cavity in a single direction.

[0012] According to some embodiments of the present invention, the outer sidewall of the conductive end has a wide side and a narrow side, the narrow side being provided with the guide groove or the guide protrusion; the wide side being provided with an identification portion for indicating the installation direction of the clamping ear portion.

[0013] According to some embodiments of the present invention, the opening of the mounting cavity gradually narrows from the outside to the inside, the conductive end gradually widens in the direction of the gripping end, and the conductive end and the mounting cavity are adapted to each other through a conical surface.

[0014] According to some embodiments of the present invention, a sealing ring is provided between the clamping ear and the mounting cavity; the sealing ring is sleeved on the outer wall of the conductive end, and when the clamping ear is installed in the mounting cavity, the sealing ring elastically abuts against the inner wall of the mounting cavity.

[0015] According to some embodiments of the present invention, the conductive end and the main body are electrically connected by a spring pin connector; the spring pin connector includes a cooperating elastic pin and a contact piece, one of the elastic pin and the contact piece is disposed on the conductive end, and the other is disposed on the inner wall of the mounting cavity; The first mounting component is arranged around the elastic pin or the contact piece disposed on the inner wall of the mounting cavity, and the second mounting component is arranged around the elastic pin or the contact piece disposed on the conductive end.

[0016] The quick-change method according to a second aspect of the present invention includes the quick-change method according to the first aspect of the present invention.

[0017] The AR glasses according to embodiments of the present invention have at least the following beneficial effects: The controller and detection module monitor the coupling state between the first and second mounting components in real time, automatically cutting off the power supply the instant the user begins to pull them out (when the coupling state changes), instead of relying on a physical switch or manual shutdown. This "power off first, then pull out" timing control completely avoids arcing, contact oxidation, or circuit damage caused by hot-plugging, significantly improving the safety and electrical reliability of quick-change operations. When the ear clip is inserted to the predetermined initial position, the controller automatically reads the identification information in the energy storage module, restoring power only after verifying it as an authorized battery. This mechanism effectively prevents the use of inferior, incompatible, or uncertified batteries, protecting the device's own safety and providing a technical basis for the management of battery consumables. During the disassembly step, the controller can distinguish between normal and abnormal pull-out signals, such as momentary magnetic fluctuations caused by force on the non-grip end, and maintain power supply to ignore interference. During the installation step, a positioning prompt is only issued when both successful identification and complete magnetic locking are met simultaneously. This design avoids erroneous power outages or error messages caused by vibration, accidental touch, etc., making the quick-change method reliable even in complex operating environments.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] Reference Figures 1 to 5 A battery quick-swap structure, comprising: The temple unit includes a main body 100 and an ear clip 110. The main body 100 is used to connect to the frame, and a mounting cavity 130 is provided at the end of the main body 100 away from the frame. The mounting cavity 130 is a cavity structure with one end open. An energy storage module is provided inside the ear clip 110. The mounting unit includes a first mounting component 140 and a second mounting component 180. The first mounting component 140 is disposed on the main body 100, and the second mounting component 180 is disposed on the clamping ear 110. The first mounting component 140 and the second mounting component 180 are mutually compatible, and the clamping ear 110 is detachably mounted on the main body 100. When the clip 110 is installed on the main body 100, the energy storage module provides power.

[0026] In the initial state, the ear clip 110 is separated from the main body 100. When the user needs to power the AR glasses, the ear clip 110 is inserted into the mounting cavity 130 of the main body 100 at the end away from the frame along the opening direction of the mounting cavity 130.

[0027] During insertion, the first mounting component 140 disposed on the main body 100 and the second mounting component 180 disposed on the clamping ear 110 cooperate to position and fix the clamping ear 110 until the clamping ear 110 is fully inserted into the mounting cavity 130. At this time, a stable detachable connection is formed between the clamping ear 110 and the main body 100.

[0028] Once the clip 110 is installed in place, its internal energy storage module establishes an electrical connection with the main body 100, thereby providing power. When the energy storage module runs out of power or the user needs to replace the battery, simply pull the clip 110 out of the mounting cavity 130 and insert another pre-charged clip 110 to quickly restore power.

[0029] The entire disassembly and assembly process requires no tools and can be completed with one hand, with power supply and installation happening simultaneously.

[0030] By incorporating a detachable clip 110 and integrating the energy storage module within it, users can quickly remove the clip 110 and replace it with a pre-charged one when the battery is depleted, without needing to connect to an external power source or wait for charging. This significantly extends the continuous use time of the AR glasses and solves the problems of short battery life and non-replaceable built-in batteries. The main body 100 has a mounting cavity 130 with an opening at one end, allowing the clip 110 to be directly inserted or removed along the opening direction. The assembly and disassembly are simple and smooth, requiring no external power supply or waiting time. With the aid of any tool, a fast battery swapping experience can be achieved with one hand, avoiding the cumbersome disassembly and inconvenience of traditional snap-on or sliding plug-in structures. Through the mutual adaptation of the first mounting component 140 and the second mounting component 180, it is ensured that the ear clip 110 is firmly connected to the main body 100 after installation and is not easy to loosen. At the same time, the ear clip 110 is completely embedded in the mounting cavity 130 and is integrated with the shape of the temple main body 100, maintaining the lightweight, thin and ergonomic design of AR glasses, without affecting wearing comfort and product aesthetics.

[0031] The first mounting component 140 is a first magnet 200, and the second mounting component 180 is a second magnet 210. The first magnet 200 and the second magnet 210 attract each other. When the clip 110 is inserted into the mounting cavity 130 of the main body 100, a magnetic force is generated between the first magnet 200 disposed in the main body 100 and the second magnet 210 disposed in the clip 110. This magnetic force guides the clip 110 to move automatically toward the correct position and provides auxiliary engagement when the clip 110 is close to the mounting position, so that the clip 110 smoothly enters the bottom of the mounting cavity 130.

[0032] Once the clip 110 is fully installed, the first magnet 200 and the second magnet 210 attract each other tightly, securing the clip 110 to the main body 100 with magnetic force to prevent accidental detachment due to shaking, vibration, or slight external force. When the user needs to replace the battery, simply apply a pulling force greater than the magnetic attraction to pull the clip 110 out of the mounting cavity 130.

[0033] Utilizing the attraction between magnets, the clip 110 features automatic guidance and assisted engagement during insertion, allowing for easy installation without precise alignment. Removal also eliminates the need to unlock any latching mechanism, enabling truly one-click, rapid battery swapping and further enhancing the convenience of single-handed operation. The first magnet 200 and the second magnet 210 attract each other, providing a continuous and constant holding force for the clip 110 during normal use. This ensures the clip 110 will not loosen due to movement or minor impacts, while also preventing wear and loosening of mechanical latches after prolonged use.

[0034] The first magnet 200 has a first inner groove 220 on its side wall, and the second magnet 210 has a second inner groove 230 on its side wall. The main body 100 is integrally formed with the first magnet 200 through the first inner groove 220, and the clamping ear 110 is integrally formed with the second magnet 210 through the second inner groove 230. The main body 100 and the first magnet 200 are integrally formed by injection molding, with the main body 100 embedded in the first inner groove 220. The clamping ear 110 and the second magnet 210 are integrally formed by injection molding, with the clamping ear 110 embedded in the second inner groove 230.

[0035] During the manufacturing process, the first magnet 200 is pre-placed in the injection mold of the main body 100, and the second magnet 210 is pre-placed in the injection mold of the clamping ear 110. The first magnet 200 has a first inner groove 220 on its side wall, and the second magnet 210 has a second inner groove 230 on its side wall.

[0036] During injection molding, molten plastic material fills the first inner groove 220 and the second inner groove 230, respectively. After the plastic cools and solidifies, the plastic material of the main body 100 is embedded in the first inner groove 220, making the first magnet 200 and the main body 100 an inseparable whole; similarly, the plastic material of the clamping ear 110 is embedded in the second inner groove 230, making the second magnet 210 and the clamping ear 110 an inseparable whole. The special shape of the inner groove (such as ring, dovetail, or irregular depression) forms a mechanical interlock after the plastic solidifies, so that even under repeated insertion and extraction forces and magnetic impact forces, the magnet cannot be detached from the shell.

[0037] After injection molding is completed, the main body 100 is embedded in the first inner groove 220 of the first magnet 200 (that is, the material of the main body 100 fills the groove), and the clamping ear 110 is embedded in the second inner groove 230 of the second magnet 210, thus realizing the full structural fixation of the magnet and the shell.

[0038] By creating internal grooves on the sidewalls of the magnets, the housing material is embedded within these grooves after injection molding, forming a three-dimensional mechanical interlock. Compared to adhesive bonding, snap-fit, or interference fits, this method significantly increases pull-out resistance, effectively resisting impacts from insertion, vibration, and drops during use, preventing the magnets from loosening or falling off. The magnets are pre-placed in the mold, and the finished part with the magnets is obtained immediately after injection molding, eliminating subsequent magnet assembly processes (such as dispensing, pressing, and ultrasonic welding), greatly reducing production time and labor costs, and making it suitable for large-scale automated production. The position of the magnets in the mold is directly guaranteed by the mold's precision, resulting in minimal relative positional error after injection molding. This ensures precise alignment of the first magnet 200 and the second magnet 210 in each product set, maximizing magnetic attraction and optimizing fit stability.

[0039] The clip portion 110 has a conductive end 240 and a gripping end 250 arranged opposite to each other; the outer side wall of the conductive end 240 is provided with a guide groove 170, and the inner side wall of the mounting cavity 130 is provided with a corresponding guide protrusion 120. Alternatively, the outer side wall of the conductive end 240 is provided with a guide protrusion 120, and the inner side wall of the mounting cavity 130 is provided with a corresponding guide groove 170; the guide groove 170 and the guide protrusion 120 are adapted to each other to restrict the clamping ear 110 from being inserted into the mounting cavity 130 in a single direction.

[0040] During the process of inserting the clip 110 into the mounting cavity 130 of the main body 100, the guide groove 170 and the guide protrusion 120 cooperate with each other to guide and prevent mistakes.

[0041] Specifically, the outer wall of the conductive end 240 and the inner wall of the mounting cavity 130 are respectively provided with a guide groove 170 and a guide protrusion 120 (the positions of the two can be interchanged). When the user inserts the clamping ear 110 in the correct direction, the guide protrusion 120 just enters the guide groove 170, and the two slide relative to each other along the insertion direction, constraining the movement trajectory of the clamping ear 110 and ensuring that it enters the bottom of the mounting cavity 130 in a straight line with a unique posture.

[0042] If the user attempts to insert the clip 110 in the wrong direction (such as upside down or left and right reversed), the guide groove 170 and the guide protrusion 120 will interfere with each other due to the mismatch in position or shape, thus preventing the clip 110 from being inserted further and thus preventing incorrect installation.

[0043] The mutual adaptation of the guide groove 170 and the guide protrusion 120 achieves three functions: first, guidance, making the insertion process smooth and stable; second, anti-reverse insertion, avoiding damage to the electrical connection terminals or failure of magnetic attraction caused by reverse or incorrect angle installation; and third, limiting, preventing the clamping ear 110 from rotating or shaking in the mounting cavity 130.

[0044] The cooperation between the guide groove 170 and the guide protrusion 120 allows the clamping ear 110 to automatically move along a predetermined trajectory during insertion, enabling smooth installation even if the user does not align it intentionally. This reduces the difficulty of operation and the requirement for visual alignment, achieving a blind-plugging experience similar to a USB interface. By setting mutually compatible guide grooves 170 and guide protrusions 120, when the user inserts it in the wrong direction, the two will physically interfere, preventing the clamping ear 110 from entering the mounting cavity 130. This effectively prevents problems such as short circuits of the conductive end 240, deformation of the elastic pin 160, and misalignment of the magnet caused by reverse insertion, improving the safety and reliability of the product. The guiding structure restricts the radial rotation and axial displacement of the clamping ear 110 within the mounting cavity 130, ensuring that the electrical connection terminals between the energy storage module and the main body 100 are always aligned, avoiding poor contact caused by shaking or vibration, and ensuring stable power supply.

[0045] The outer side wall of the conductive end 240 has a wide side and a narrow side. The narrow side is provided with a guide groove 170 or a guide protrusion 120; the wide side is provided with an identification part 190 for indicating the installation direction of the clamping ear part 110.

[0046] A recognition section 190 is provided on the wide side, which conveys directional information to the user through visual or tactile means. When the user is about to insert the clip 110, he / she can quickly determine the correct orientation of the clip 110 by observing the recognition section 190 on the wide side, and thus perform the insertion operation in the correct posture.

[0047] The identification part 190 and the guide structure on the narrow side form a dual foolproof mechanism: the identification part 190 provides visual guidance before insertion, and the guide structure provides physical constraints during insertion, together ensuring that the clip part 110 is installed in the only correct direction.

[0048] By placing the guide groove 170 or guide protrusion 120 on the narrow side with a smaller width, limited space resources are fully utilized, avoiding interference or space waste that might occur if the guide structure is placed on the wide side. This is beneficial for the compact and thin design of the overall structure. The identification part 190 is placed on the wide side with a larger area, providing good visibility and recognition. Users can quickly identify the correct orientation of the clip ear 110 without careful observation before insertion, reducing the requirements for operational precision. This is especially suitable for use in low-light or distracted environments.

[0049] The opening of the mounting cavity 130 gradually narrows from the outside to the inside, and the conductive end 240 gradually expands towards the holding end 250. The conductive end 240 and the mounting cavity 130 are mutually adapted through a conical surface.

[0050] The opening of the mounting cavity 130 gradually narrows from the outside to the inside, that is, the inner wall of the mounting cavity 130 gradually narrows from the opening to the bottom, forming an inner conical surface with a certain taper. The conductive end 240 gradually expands towards the holding end 250, that is, the outer wall of the conductive end 240 gradually expands from the front end (insertion end) towards the holding end 250, forming an outer conical surface with a certain taper.

[0051] When the user inserts the clip 110 into the mounting cavity 130 of the main body 100, the front end (smaller in size) of the conductive end 240 first enters the opening (larger in size) of the mounting cavity 130. As the insertion depth increases, the gradually expanding outer conical surface of the conductive end 240 gradually contacts and fits against the gradually contracting inner conical surface of the mounting cavity 130.

[0052] When the clamping lug 110 is inserted to the predetermined depth, the outer conical surface and the inner conical surface completely match, forming a conical fit. Since the conical surface has a self-centering and alignment function, this fit can automatically guide the clamping lug 110 to the center position of the mounting cavity 130, eliminating eccentricity caused by manufacturing tolerances or operational deviations.

[0053] Simultaneously, the conical fit generates axial guiding force and radial clamping force during insertion and removal. During insertion, the conical surface allows the clamping lug 110 to slide in smoothly; during removal, the conical surface provides uniform resistance to prevent the clamping lug 110 from accidentally loosening. When the magnetic attraction or locking force tightens the clamping lug 110, the conical fit further enhances the rigidity and stability of the connection.

[0054] The conical surface fit has a self-centering characteristic, which automatically guides the clip 110 to the center position of the mounting cavity 130 during insertion, avoiding jamming or insertion difficulties caused by manual alignment deviation, making the insertion and removal actions smoother and less strenuous. After the conical surfaces are fitted, there is a gapless fit between the conductive end 240 and the mounting cavity 130, effectively eliminating radial wobble and axial movement, making the clip 110 and the main body 100 form a rigid whole, improving the structural stability and wearing reliability of the AR glasses temples.

[0055] A sealing ring is provided between the clamping ear 110 and the mounting cavity 130; the sealing ring is sleeved on the outer wall of the conductive end 240, and when the clamping ear 110 is installed in the mounting cavity 130, the sealing ring elastically abuts against the inner wall of the mounting cavity 130.

[0056] A sealing ring is fitted on the outer wall of the conductive end 240 of the clamping part 110. The sealing ring is usually made of an elastic material (such as silicone, rubber, etc.) and has compressibility and resilience.

[0057] When the clamping lug 110 is inserted into the mounting cavity 130 of the main body 100, the sealing ring enters the mounting cavity 130 together with the conductive end 240. As the insertion depth increases, the outer circumferential surface of the sealing ring gradually contacts the inner wall of the mounting cavity 130. When the clamping lug 110 continues to be pushed in, the inner wall of the mounting cavity 130 exerts radial pressure on the sealing ring, causing the sealing ring to undergo elastic compression deformation.

[0058] Once the clamp 110 is fully installed, the sealing ring is compressed, with its outer surface tightly fitted against the inner wall of the mounting cavity 130, and its inner surface tightly fitted against the outer wall of the conductive end 240. This forms a surrounding sealing barrier between the outer wall of the conductive end 240 and the inner wall of the mounting cavity 130. This sealing barrier prevents external moisture, dust, sweat, and other foreign matter from entering the interior through the openings of the mounting cavity 130, protecting internal components such as the energy storage module, electrical connection terminals, and magnets.

[0059] In addition, the elastic compression of the sealing ring generates a certain axial thrust, but since the magnetic attraction or snapping force is much greater than this thrust, it does not affect the secure installation of the clamp ear 110. When pulled out, the sealing ring gradually returns to its original shape, without affecting the smoothness of disassembly.

[0060] Electrical connection is achieved between the conductive end 240 and the main body 100 through a spring pin connector; the spring pin connector includes a cooperating elastic pin 160 and a contact piece 150, one of the elastic pin 160 and the contact piece 150 is disposed on the conductive end 240, and the other is disposed on the inner wall of the mounting cavity 130. The first mounting component 140 is arranged around the elastic pin 160 or contact piece 150 disposed on the inner wall of the mounting cavity 130, and the second mounting component 180 is arranged around the elastic pin 160 or contact piece 150 disposed on the conductive end 240.

[0061] The sealing ring forms an elastic compression seal between the conductive end 240 and the inner wall of the mounting cavity 130, effectively preventing external foreign matter such as moisture, sweat, and dust from entering the mounting cavity 130. This gives the battery quick-change structure a higher protection rating (such as IP54, IP67), meeting the needs of various scenarios such as outdoor sports, industrial sites, and rainy weather. The sealing ring isolates external moisture and contaminants, preventing the conductive end 240 from failing due to corrosion or short circuits. It also prevents the magnet from rusting and the circuit board from getting damp, significantly improving the long-term reliability and lifespan of the product. The sealing ring acts as an elastic buffer during the insertion of the clamp 110, reducing the hard impact between the clamp 110 and the bottom of the mounting cavity 130, protecting the electrical connection terminals (such as spring pins) from excessive impact force, and extending the insertion and removal life.

[0062] Reference Figures 1 to 1 A quick-change battery structure is proposed for AR glasses. The structure includes a temple unit and a mounting unit.

[0063] The temple unit consists of a main body 100 and an ear clip 110. The main body 100 is used to connect to the frame, and a mounting cavity 130 is provided at the end of the main body 100 away from the frame. The mounting cavity 130 is a cavity structure with one open end, facing outward. An energy storage module, such as a rechargeable lithium battery, is installed inside the ear clip 110.

[0064] The mounting unit includes a first mounting component 140 and a second mounting component 180. The first mounting component 140 is disposed on the main body 100, and the second mounting component 180 is disposed on the clip portion 110. The first mounting component 140 and the second mounting component 180 are adapted to each other, so that the clip portion 110 is detachably mounted on the main body 100. When the clip portion 110 is mounted on the main body 100, the energy storage module automatically powers the AR glasses.

[0065] Specifically, the first mounting component 140 is at least one first magnet 200, and the second mounting component 180 is at least one second magnet 210. The first magnet 200 and the second magnet 210 attract each other. To securely fix the magnets, the sidewall of the first magnet 200 has a first inner groove 220, and the sidewall of the second magnet 210 has a second inner groove 230. The main body 100 is integrally formed with the first magnet 200 by injection molding, with the injection molding material embedded in the first inner groove 220, so that the first magnet 200 is embedded in the main body 100; similarly, the clamping ear 110 is integrally formed with the second magnet 210 by injection molding, with the injection molding material embedded in the second inner groove 230, so that the second magnet 210 is embedded in the clamping ear 110.

[0066] The clip portion 110 has a conductive end 240 and a gripping end 250 disposed opposite to each other. The conductive end 240 is used to insert into the mounting cavity 130 and is electrically connected to the main body 100, and the gripping end 250 is used by the user to pinch for insertion and removal operations.

[0067] To ensure that the clamping ear 110 is inserted in the correct direction, a foolproof guide structure is provided. A guide groove 170 is provided on the outer wall of the conductive end 240, and a corresponding guide protrusion 120 is provided on the inner wall of the mounting cavity 130; or conversely, a guide protrusion 120 is provided on the outer wall of the conductive end 240, and a guide groove 170 is provided on the inner wall of the mounting cavity 130. The guide groove 170 and the guide protrusion 120 are mutually adapted. When the user inserts it in the wrong direction, the two interfere with each other, preventing further insertion, thereby restricting the clamping ear 110 to enter the mounting cavity 130 only in a single direction.

[0068] The outer wall of the conductive end 240 is divided into a wide side and a narrow side, with the narrow side being narrower and the wide side being wider. The aforementioned guide groove 170 or guide protrusion 120 is provided on the narrow side. An identification part 190 is provided on the wide side, which can be a pit, a dot, a color mark, or a laser symbol, used to indicate to the user the correct installation direction of the clip ear 110.

[0069] The opening of the mounting cavity 130 gradually narrows from the outside to the inside, forming an inner conical surface. The conductive end 240 gradually widens from the insertion end to the gripping end 250, forming an outer conical surface. When the clamping ear 110 is inserted into the mounting cavity 130, the outer conical surface and the inner conical surface fit together, which plays a role in self-centering guidance and eliminating gaps, making the connection more stable.

[0070] A sealing ring is fitted on the outer wall of the conductive end 240. The sealing ring is made of an elastic material such as silicone. When the clamping lug 110 is fully inserted into the mounting cavity 130, the sealing ring is compressed between the outer wall of the conductive end 240 and the inner wall of the mounting cavity 130, forming an elastic contact, thereby preventing moisture, dust and sweat from entering the mounting cavity 130 and improving the protection level.

[0071] Electrical connection is achieved between the conductive end 240 and the main body 100 via a spring-loaded connector. The spring-loaded connector includes mating spring-loaded pins 160 and contact pieces 150. One of the spring-loaded pins 160 and contact pieces 150 is mounted on the conductive end 240, and the other is mounted on the inner wall of the mounting cavity 130. Furthermore, a first mounting assembly 140 (a first magnet 200) is arranged around the periphery of the spring-loaded pin 160 or contact piece 150 located on the inner wall of the mounting cavity 130; a second mounting assembly 180 (a second magnet 210) is arranged around the periphery of the spring-loaded pin 160 or contact piece 150 located on the conductive end 240. This surrounding arrangement ensures a uniform distribution of magnetic attraction, guaranteeing stable electrical contact.

[0072] In use, the user holds the gripping end 250 of the clip 110, observes the identification part 190 on the wide side, and aligns the conductive end 240 with the opening of the mounting cavity 130 in the correct direction. During insertion, the guide groove 170 and guide protrusion 120 guide the direction, the conical surface automatically centers, the sealing ring gradually compresses, and finally the magnets attract each other, pulling the clip 110 into place. At this time, the elastic pin 160 and contact piece 150 elastically abut, and the energy storage module supplies power to the temple body 100. When replacing the battery, simply pull out the clip 110 and replace it with a new or fully charged clip 110.

[0073] The AR glasses according to a second aspect of the present invention include the battery quick-change structure of the first aspect of the present invention.

[0074] By configuring a quick-replaceable clip-on energy storage module, users can quickly replace the backup module when the power is low without interrupting use or connecting an external power source, effectively meeting the needs of long-term wear in all scenarios; the clip-on part 110 is fully embedded in the mounting cavity 130 of the main body 100, flush and fitting with the shape of the temple, maintaining the lightweight, thin and ergonomic design of AR glasses, taking into account both comfort and aesthetics.

[0075] By configuring a quick-replaceable clip-on energy storage module, users can rapidly replace the backup module when the battery is low, without interrupting use or requiring an external power source, completely eliminating battery anxiety and meeting the needs of long-term wear in all scenarios. The clip-on part 110 is fully embedded in the mounting cavity 130 of the main body 100, flush and fitting snugly with the shape of the temples, without any protrusions, maintaining the lightweight, thin, and ergonomic design of the AR glasses, taking into account both wearing comfort and product aesthetics.

[0076] The battery quick-swap method according to a third aspect of the present invention includes the battery quick-swap structure of the first aspect of the present invention.

[0077] The battery quick-change structure also includes a controller and a detection module. The detection module is used to detect the relative position or adsorption state between the first mounting component 140 and the second mounting component 180. The quick battery swapping method includes the following steps: Disassembly preparation steps: The controller monitors the coupling state between the first mounting component 140 and the second mounting component 180 in real time through the detection module; when a change in the coupling state indicating that the clamp 110 is pulled outward is detected, the controller immediately cuts off the power supply path from the energy storage module to the electrical load. Disassembly steps: After the power supply is cut off, apply an external force to overcome the attraction between the first mounting component 140 and the second mounting component 180, and pull the clip 110 out of the mounting cavity 130. Installation and detection steps: When the user inserts the ear clip 110 to be replaced into the mounting cavity 130 to the predetermined initial position, the detection module detects the proximity signal between the first mounting component 140 and the second mounting component 180. The controller starts and initiates the identification process. The controller starts the identification process to read the identification information in the energy storage module. Installation confirmation steps: After the controller verifies that the identification information is an authorized battery, it controls the power pin of the energy storage module to conduct and restore power supply; at the same time, the controller confirms through the detection module that the first mounting component 140 and the second mounting component 180 are completely attached and locked, and issues a prompt indicating that the installation is in place through the prompt module on the temple unit or the frame. During the installation and testing process, if the controller fails to read valid identification information or identifies an incompatible battery, it will maintain the power supply cut-off state and issue an error message. During the disassembly preparation process, if the detection module detects an abnormal pull-out signal, such as a momentary magnetic fluctuation caused by force applied to the non-grip end 250, the controller will maintain power supply and ignore the signal.

[0078] The battery quick-swap method of the third aspect of the present invention is implemented based on the battery quick-swap structure of the first aspect embodiment, and additionally configured with a controller and a detection module.

[0079] Under normal use, the clip 110 is installed in the mounting cavity 130 of the main body 100 by the adsorption and locking of the first mounting component 140 and the second mounting component 180, and the energy storage module supplies power to the electrical load normally through the electrical connection interface. The controller monitors the relative position or adsorption state between the first mounting component 140 and the second mounting component 180 in real time through the detection module, that is, the coupling state between the two.

[0080] When the user needs to remove the battery, they begin to pull out the clip 110. During this process, a slight change occurs in the gap or relative position between the first mounting component 140 and the second mounting component 180, and the coupling state changes accordingly. The detection module transmits this change signal to the controller in real time. The controller determines that the change indicates that the clip 110 is being pulled out and immediately cuts off the power supply path from the energy storage module to the electrical load. After the power supply is completely cut off, the user continues to apply external force to overcome the suction force and completely pulls the clip 110 out of the mounting cavity 130. No electric arc or contact damage occurs during this process.

[0081] When the user needs to install a new clip 110, the clip 110 is inserted into the mounting cavity 130. When inserted to the predetermined initial position, that is, when the first mounting component 140 and the second mounting component 180 are not yet fully adsorbed but are close enough to be detected, the detection module detects the proximity signal between them, the controller is activated, and the identification process is automatically initiated. The controller reads the identification information stored in the energy storage module through the data pins of the electrical connection interface. This identification information includes the battery identification code or power parameters.

[0082] The controller compares the read identification information with the preset authorization conditions. If it verifies that the battery is authorized, it controls the power supply output of the energy storage module to be turned on, restoring power supply to the electrical load. At the same time, the controller continues to confirm through the detection module whether the first mounting component 140 and the second mounting component 180 are fully attached and locked. When both are fully in place, the controller drives the prompt module on the temple unit or the frame to issue an installation prompt, informing the user that the installation is successful.

[0083] If the controller fails to read valid identification information or identifies an incompatible battery during the installation and testing process, it will maintain the power supply cut-off state, issue an error message, and prohibit the battery from supplying power to the device.

[0084] During the disassembly preparation step, if the detection module detects an abnormal pull-out signal, such as a momentary magnetic fluctuation caused by the force applied to the non-grip end 250 due to a sudden impact or vibration of the device, the controller determines that the signal is not caused by normal human pull-out, and maintains the power supply state and ignores the abnormal signal to avoid accidental power outage due to misjudgment.

[0085] Through the coordinated operation of the above steps, a safe, intelligent, reliable battery quick-swap operation with the ability to prevent misjudgment is achieved.

[0086] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
