Currently, some AirTag cases on the market have a cover to shield the window, which clips directly onto the case. However, gaps exist between the cover and the case, allowing liquids to seep into the case, failing to effectively protect the AirTag and causing damage. Furthermore, the waterproofing performance is insufficient for practical use. Utility Model Content

Detailed Implementation

[0036] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0038] With the widespread use of wireless positioning devices (such as Apple AirTag) in outdoor tracking and object location scenarios, the waterproof and dustproof performance of their protective devices has become a critical requirement. Existing protective cases mostly adopt simple shell splicing or cover structures, which have problems such as sealing failure and excessive gaps after installation, allowing water and dust to easily penetrate the interior, causing damage to the device or performance degradation.

[0039] Therefore, this application provides a wireless positioning device protection device, which significantly improves waterproof performance and installation stability by improving the matching structure between the cover and the protective element and adding sealing and positioning structures, thereby solving the protection defects of existing protection devices.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Please see Figures 1-5This utility model embodiment demonstrates a protective device for a wireless positioning device 3, comprising: a protective element 1 and a cover 2. The protective element 1 includes a first base portion 11 and a second base portion 12, the central axis 14 of the first base portion 11 and the second base portion 12 coincides, the first base portion 11 includes a enclosure portion 111 and a window 112, the enclosure portion 111 converges from the periphery of the first base portion 11 toward the central axis 14, and the window 112 is formed at the center of the convergence of the enclosure portion 111; an internal space 13 is formed by the enclosure between the first base portion 11 and the second base portion 12, for accommodating the wireless positioning device 3; the cover 2 is housed in the internal space 13 and is used to cover the window 112; wherein, when the wireless positioning device 3 is installed in the internal space 13, the upper surface of the wireless positioning device 3 is in contact with the lower surface of the cover 2, and the edge of the upper surface of the cover 2 is in contact with the inner wall surface of the enclosure portion 111 to form a surface contact seal.

[0042] Reference Figure 2Specifically, the protective element 1 can be a protective sleeve structure or a protective shell structure, used to enclose and protect the wireless positioning device 3. The first base portion 11 and the second base portion 12 constitute the main body of the protective element 1. The central axis 14 of the first base portion 11 coincides with the central axis 14 of the second base portion 12, and they are distributed vertically. The first base portion 11 serves as the upper half of the protective element 1, and the second base portion 12 serves as the lower half. The first base portion 11 and the second base portion 12 enclose an internal space 13, which is used to house the wireless positioning device 3. The structure of the first base portion 11 includes a enclosure portion 111 and a window 112. The enclosure portion 111, as a protective structure, converges from the periphery of the first base portion 11 towards the center but does not close, so that the convergence center of the enclosure portion 111 defines the window 112. The entire first base portion 11 has a flat-topped arched structure, with the window 112 at the flat top, revealing the internal space 13. Window 112 serves as the installation entry point. The cover 2 is inserted into the internal space 13 through window 112 for installation. The cover 2 shields window 112, isolating it from the outside world and preventing liquids or dust from entering the internal space 13, thus protecting the wireless positioning device 3. When installing the wireless positioning device 3 into the internal space 13, the cover 2 is first placed on the upper surface of the wireless positioning device 3. Then, the cover 2 and the wireless positioning device 3 are inserted together through window 112 into the internal space 13 for installation, thus completing the assembly. Within the internal space 13, the lower surface of the cover 2 is flush with the upper surface of the wireless positioning device 3, while the central area of ​​its upper surface shields window 112. The edge area of ​​its upper surface is flush with the inner wall of the enclosure 111, forming a surface-to-surface seal. On the one hand, by utilizing the large-area continuous contact between the upper surface edge of the cover 2 and the inner wall of the enclosure 111, a sealed interface is formed that runs through the entire contact surface. The liquid needs to migrate slowly along the microscopic gaps of the entire contact surface. The liquid penetration path is long, and the larger the contact area of ​​the continuous sealed interface, the greater the resistance to liquid penetration. Therefore, the sealing performance is better, and the waterproof effect is improved. On the other hand, when the wireless positioning device 3 is installed in the internal space 13, it will generate a certain amount of compressive force, pressing the cover 2 against the inner wall of the enclosure 111. The compressive force on the cover 2 makes it fit tightly against the inner wall of the enclosure 111. The contact surface will deform, which will greatly reduce the width of the gap that the liquid can penetrate, thereby improving the sealing performance and waterproof effect.

[0043] In this embodiment, the edge of the upper surface of the cover 2 is tightly fitted with the inner wall of the enclosure 111 to form a surface contact seal, which increases the resistance to liquid penetration. External liquids are less likely to seep into the internal space 13 through the gap, thereby improving the sealing performance, enhancing the waterproof performance, protecting the wireless positioning device 3, and extending its service life.

[0044] Continue to refer to Figure 2 In one embodiment, the contact surface between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111 is non-planar. Specifically, the contact surface between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111 is designed as a non-planar structure. This manifests as one of them having continuous arc-shaped protrusions, wavy surfaces, or sawtooth-shaped truncated pyramids, while the other forms a matching groove or complementary curved surface, creating a line-to-surface or point-to-surface interlaced sealing interface when they come into contact. For example, the inner wall of the enclosure 111 can be a sinusoidal concave curved surface, and correspondingly, the edge area of ​​the upper surface of the cover 2 protrudes outward to form a cosine wave structure, forming multiple continuous sealing lines in the circumferential direction when they are fitted together. Compared to planar bonding, the non-planar contact surface, while maintaining a large area of ​​continuous sealing, further improves the tightness of contact and long-term reliability through geometric optimization, meeting the stringent waterproof requirements of outdoor environments. It is understood that the contact surface can also be other non-planar structures, such as an arc surface. Specifically, the inner wall of the enclosure 111 has a continuous arc-shaped concave curved surface structure, while the upper surface edge of the cover 2 is adapted to form a matching arc-shaped arched structure, so that the two form an arc-shaped fitting structure when in contact. When the wireless positioning device 3 is installed in the internal space 13, the cover 2 is subjected to vertical compression force, and its arc-shaped arched edge will undergo radial expansion deformation along the arc-shaped inner wall of the enclosure 111, forming a tight fit that matches the curvature of the inner wall of the enclosure 111. The radius of curvature of the arc-shaped contact surface can be set according to actual needs to maximize the length of the contact path within a limited space. In the assembled state, the arc-shaped arched structure of the edge of the cover 2 is tightly fitted with the arc-shaped concave curved surface structure of the inner wall of the enclosure 111, and the contact portion between the two extends continuously in the circumferential direction to form an annular closed sealing band. This arc-shaped contact structure offers the advantage of dual sealing reinforcement: First, under static conditions, the tangent direction of the arc-shaped contact surface forms an angle with the liquid penetration path, forcing the liquid to deflect along the curved surface to penetrate, significantly increasing penetration resistance; second, during dynamic compression, the arc-shaped arched structure at the edge of the cover 2 undergoes plastic deformation, pressing against the inner wall of the enclosure 111, further reducing the actual gap width of the contact interface. Compared to a planar contact sealing structure, the arc-shaped contact surface design in this embodiment significantly increases the difficulty of liquid penetration and improves waterproofing capabilities.

[0045] Continue to refer to Figure 2In one embodiment, the contact surface between the edge of the upper surface of the cover 2 and the inner wall surface of the enclosure 111 extends from the window 112 to the edge of the first base portion 11. Specifically, the contact surface between the edge of the upper surface of the cover 2 and the inner wall surface of the enclosure 111 starts from the periphery of the window 112 and extends continuously outward along the inner wall surface of the enclosure 111 to the edge terminal of the first base portion 11, forming a continuous sealing interface that runs through the entire height of the enclosure 111. The contact surface extends from the window 112 to the edge of the first base portion 11, making the liquid penetration path length reach the full height of the inner wall of the enclosure 111 (i.e., the distance from the window 112 to the edge of the base), which is longer than the penetration path of a traditional partial contact design (such as sealing only near the window 112). The liquid needs to migrate along the entire inner wall surface, increasing the penetration resistance and significantly improving the waterproof rating.

[0046] In one embodiment, the radius of the first base portion 11 is R1, and the radius of the window 112 is R2. R2 and R1 satisfy the following condition: 15% ≤ (R1-R2) / R1 ≤ 65%. Specifically, the radius of the first base portion 11 is R1, and the radius of the window 112 is R2. The two satisfy the proportional relationship of 15% ≤ (R1-R2) / R1 ≤ 65%, where (R1-R2) corresponds to the width of the contact surface between the edge of the upper surface of the cover 2 and the inner wall of the enclosure portion 111. This design achieves an optimized balance between waterproof performance and ease of assembly by precisely limiting the width of the contact surface: when (R1-R2) / R1≥15%, the contact surface width is wide enough to ensure sufficient resistance length when liquid penetrates along the tortuous path of the non-planar interface, avoiding seal failure due to an excessively narrow contact surface; when (R1-R2) / R1≤65%, the window size R2 retains sufficient opening space (for example, when R1=10cm, R2≥3.5cm), allowing the cover 2 and the wireless positioning device 3 to be smoothly assembled through the window 112, avoiding installation jamming or excessive compression of the flexible material of the protective element 1 due to an excessively small window 112. This proportional constraint ensures, on the one hand, that the window 112 is large enough to smoothly accommodate the combination of the cover 2 and the wireless positioning device 3, allowing the operator to apply force naturally to complete the assembly, avoiding installation jamming or scratching of the device surface due to an excessively small window 112; on the other hand, the limited proportion of the window 112 ensures that the enclosure 111 retains a sufficiently wide annular contact area, and the non-planar contact surface between the edge of the cover 2 and the inner wall of the enclosure 111 covers the entire circumferential range of the upper surface edge of the cover 2, forcing liquids or dust to migrate along a non-planar path. Compared to a fully open window 112 structure without a defined proportion, this significantly extends the penetration path and increases migration resistance. The aforementioned proportional range precisely balances the contradictory requirements of ease of assembly and sealing strength, ensuring smooth installation operations while achieving a synergistic improvement in waterproof and dustproof performance through optimized contact area and path complexity. This solves the dual problems of sealing failure and assembly difficulty caused by blindly enlarging or shrinking the window 112 size in traditional designs.

[0047] In one embodiment, a sealing structure is provided between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111. Specifically, a sealing structure is added between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111. The sealing structure can be of various types, such as a sealing ring, a sealing adhesive layer, or a tongue-and-groove structure, and is not limited here. By introducing the sealing structure, liquid penetration can be blocked between the cover 2 and the enclosure 111, significantly improving the ability to prevent liquid penetration. Compared with a basic design without a sealing structure, this significantly improves waterproof and dustproof performance, effectively preventing water, dust, and other impurities from entering the internal space 13 from between the cover 2 and the enclosure 111, providing more reliable protection for the wireless positioning device 3.

[0048] Reference Figure 2and Figure 3 In one embodiment, the sealing structure includes an annular groove 21 and an annular protrusion 113. The annular protrusion 113 is located on one of the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111, and the annular groove 21 is located on the other of the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111. The annular protrusion 113 is fitted into the annular groove 21. Specifically, the sealing structure includes a mutually cooperating annular groove 21 and an annular protrusion 113. The annular protrusion 113 is integrally formed on the inner wall of the enclosure 111, extending continuously in the circumferential direction to form a closed loop structure, and its cross-section is a semi-circular rib. The annular groove 21 is correspondingly opened on the edge of the upper surface of the cover 2, and its cross-section is an arc-shaped groove matching the rib, forming an interference fit space. Of course, it is understood that the positions of the annular groove 21 and the annular protrusion 113 can also be interchanged, which will not be elaborated here. When the wireless positioning device 3 is installed in the internal space 13, the cover 2 is compressed and moves towards the inner wall of the enclosure 111, causing the ribs to embed into the grooves and generate radial compression deformation, filling the gaps in the grooves. Through the interlocking design of the annular groove 21 and the protrusions, the penetration path of liquid is blocked, further improving the waterproof performance.

[0049] In one embodiment, a positioning structure is provided between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111. Specifically, a positioning structure is added between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111. The positioning structure can be of various types, such as the cooperation between a positioning protrusion and a positioning groove 23, the cooperation between a guide post and a guide hole, a magnetic positioning assembly, etc., and is not limited here. By introducing the positioning structure, a precise relative positional relationship can be established between the cover 2 and the enclosure 111, ensuring that they are quickly aligned and without offset during assembly, avoiding local sealing failure due to installation deviation. At the same time, the positioning structure can constrain the displacement of the cover 2 in the internal space 13, preventing it from loosening or misaligning during long-term use or when subjected to external impact, ensuring that the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111 always maintain a stable surface contact seal. This structure enhances the reliability of the sealing interface through physical limiting, significantly improving waterproof and dustproof performance compared to the basic design without a positioning structure. It effectively prevents water, dust and other impurities from entering the internal space 13 from between the cover 2 and the enclosure 111, providing more reliable protection for the wireless positioning device 3.

[0050] Reference Figure 2 and Figure 3In one embodiment, the positioning structure includes an annular groove 21 and an annular protrusion 113. The annular protrusion 113 is located on one of the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111, and the annular groove 21 is located on the other of the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111. The annular protrusion 113 is fitted into the annular groove 21. Specifically, the positioning structure includes a mutually cooperating annular groove 21 and an annular protrusion 113. The annular protrusion 113 is integrally formed on the inner wall of the enclosure 111, extending continuously in the circumferential direction to form a closed loop structure, and its cross-section is a semi-circular rib. The annular groove 21 is correspondingly opened on the edge of the upper surface of the cover 2, and its cross-section is an arc-shaped groove matching the semi-circular rib, forming a guide and limiting space. Of course, it is understood that the positions of the annular groove 21 and the annular protrusion 113 can also be interchanged, which will not be elaborated here. When the cover 2 is installed into the internal space 13, the annular protrusion 113 is embedded along the annular groove 21, achieving precise alignment through the cooperation of the concave and convex structures, while simultaneously limiting the displacement of the cover 2. Through the interlocking design of the annular groove 21 and the annular protrusion 113, a mechanical limiting relationship is established between the cover 2 and the enclosure 111, ensuring rapid alignment without misalignment during assembly and effectively restraining the shaking of the cover 2 during use, so that the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111 always maintain a stable contact position. This structure, through the precise matching of geometric shapes, significantly improves assembly accuracy and structural stability, providing reliable positional assurance for the surface contact sealing interface and effectively avoiding sealing failure caused by the misalignment of the cover 2.

[0051] Reference Figure 3 In one embodiment, the lower surface of the cover 2 is recessed to form a positioning groove 23, which is used to accommodate the top of the upper surface of the wireless positioning device 3. Specifically, the lower surface of the cover 2 is recessed to form a positioning groove 23 that matches the top contour of the upper surface of the wireless positioning device 3. Its inner wall surface forms a guiding fit space with the top of the device. During assembly, the operator inserts the top of the wireless positioning device 3 into the positioning groove 23. The circumferential constraint of the device edge by the inner wall of the groove enables the cover 2 and the device to be quickly pre-positioned, forming a stable temporary assembly. Then, the assembly is pushed into the internal space 13 along the window 112 of the protective element 1 to complete the installation, avoiding the slippage and misalignment problem caused by the smooth surface of the device when the cover 2 is installed alone. After installation, the positioning groove 23 continuously restricts the horizontal movement of the device in the internal space 13, preventing the device from relative displacement with the lower surface of the cover 2 due to external vibration or impact. This ensures that the pressure distribution of the sealing interface between the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111 is uniform, while eliminating the risk of local increase in sealing gap caused by device tilting. This achieves dual positioning protection from the assembly stage to the use stage, significantly improving assembly efficiency and sealing reliability.

[0052] Continue referring to the reference Figure 3 In one embodiment, the periphery of the cover 2 is bent toward the sidewall of the wireless positioning device 3 to form a cover edge 22, the inner wall of the cover edge 22 being used to fit against at least a portion of the sidewall of the wireless positioning device 3. Specifically, the periphery of the cover 2 is bent towards the side wall of the wireless positioning device 3 to form an annular cover edge 22. The cover edge 22 extends downward along the edge of the cover 2 and partially wraps around the side wall of the wireless positioning device 3, with its inner wall abutting against the side wall of the device. This structure achieves pre-positioning of the device by wrapping the side wall of the device with the cover edge 22. When the cover 2 is placed on the upper surface of the wireless positioning device 3, the contact between the cover edge 22 and the side wall of the device creates a mechanical limiting effect, guiding the operator to accurately align the relative position of the cover 2 and the device. Subsequently, the cover 2 and the device can be smoothly pushed into the internal space 13 from the window 112 as a whole module to complete the assembly. The bending structure of the cover edge 22 automatically corrects the offset of the cover 2 through the contact with the side wall during the installation process, avoiding misalignment of the sealing interface caused by manual alignment deviation. At the same time, it simplifies the assembly steps and solves the technical problems of easy angle tilting and difficulty in quick positioning when the cover 2 and the device are installed separately in existing protective devices. This significantly improves the assembly efficiency and reduces the risk of sealing failure caused by installation errors.

[0053] Reference Figure 2 and Figure 4 In one embodiment, an annular positioning step 114 protrudes from the inner wall of the first base portion 11 or the second base portion 12, and the annular positioning step 114 supports the lower edge of the cover 2. Specifically, the annular positioning step 114 is integrally formed on the inner wall of the first base portion 11 or the second base portion 12, and the annular positioning step 114 extends continuously in the circumferential direction to form a closed-loop support structure. Its top surface is a horizontal bearing surface, forming a surface contact support with the lower edge of the cover 2. When the cover 2 is installed in the internal space 13, its lower edge is precisely seated on the annular positioning step 114, and the upper surface of the step provides stable support for the cover 2, restricting its downward displacement. In this way, the cover 2 is precisely fixed in this position by mechanical limiting, avoiding sinking or tilting of the cover 2 due to misoperation during installation or vibration during use. Under vibration or impact load, it suppresses the separation of the sealing interface between the cover 2 and the enclosure 111, maintains the integrity of the sealing path, and ensures that the edge of the upper surface of the cover 2 and the inner wall of the enclosure 111 always maintain the predetermined contact pressure and sealing state. The setting of the annular positioning step 114 also forms a clear assembly reference between the cover 2 and the base, allowing the combination of the cover 2 and the wireless positioning device 3 to be quickly aligned with the window 112 and pushed into the installation position, making installation more convenient.

[0054] In other embodiments, at least one shock-absorbing groove is recessed into the inner wall of the second base portion 12. Specifically, the shock-absorbing groove is integrally formed into the inner wall of the second base portion 12, and its shape can be designed according to actual needs, commonly rectangular, circular, or elliptical, and is not limited here. The depth of the shock-absorbing groove can be adjusted according to the size of the second base portion 12 and the expected impact force. The shock-absorbing grooves are distributed circumferentially along the inner wall of the second base portion 12, and the number can be set according to protection requirements, with at least one. When the wireless positioning device 3 is installed in the internal space 13, if the device is subjected to external impact force (such as drop or collision), the shock-absorbing groove can play an important role. The existence of the groove allows the inner wall of the second base portion 12 to have a certain elastic deformation space. When the impact force is transmitted to the second base portion 12, the inner wall material can deform into the groove, thereby absorbing and dispersing the impact force. This elastic deformation can effectively buffer the direct impact on the wireless positioning device 3, reducing the risk of damage to the device due to external force.

[0055] Continue to refer to Figure 4 In one embodiment, the protective element 1 further includes a surrounding edge 15, which is arranged around the junction of the sidewalls of the first base portion 11 and the second base portion 12. Specifically, the surrounding edge 15 is an outwardly flared skirt structure surrounding the junction of the sidewalls of the first base portion 11 and the second base portion 12. Its diameter is larger than the outer diameter of the first and second base portions 12, and its cross-section is arc-shaped or right-angled outwardly extended, continuously closed along the circumference of the base portion. The surrounding edge 15 can be integrally formed with the first and second base portions 12 by injection molding, and its outer wall surface extends outward to form a protruding protective edge, forming full coverage protection for the junction of the base portions. When the protective device is subjected to a side impact or drop, the surrounding edge 15 preferentially contacts the external object, absorbing the impact force through its own elastic deformation or rigid support, avoiding direct damage to the first and second base portions 12, and significantly improving the impact resistance of the protective device.

[0056] Continue to refer to Figure 3 In one embodiment, the protective element 1 further includes an attachment portion 16, which is formed by the sidewalls of the first base portion 11 and the second base portion 12 extending in a direction away from the central axis 14. Specifically, the protective element 1 further includes an attachment portion 16 formed by the sidewalls of the first base portion 11 and the second base portion 12 extending horizontally in a direction away from the central axis 14 (Y direction), and is integrally formed with the base portion. The shape of the attachment portion 16 can be designed as rectangular, circular, or irregular polygonal. In this embodiment, the attachment portion 16 is a lug structure. This structure provides an external fixing point for the protective device through the outwardly extending lug. When the user needs to hang the device on a keychain, backpack strap, or car mount, the through hole or buckle slot on the lug can be used directly to adapt to the lanyard, clip, or fixing bracket, realizing the portability or scenario-based application of the protective device.

[0057] Reference Figure 1 and Figure 3 In this embodiment, an attachment channel 161 is provided on the end of the attachment portion 16 away from the central axis 14. The axis of the attachment channel 161 is perpendicular to the central axis 14, and the attachment channel 161 extends through the end in a direction perpendicular to the extension of the attachment portion 16 (X direction) and has a preset length. Specifically, after the attachment portion 16 extends from the sidewalls of the first base portion 11 and the second base portion 12 in a direction away from the central axis 14, an attachment channel 161 is provided at its end away from the central axis 14. The axis of the attachment channel 161 is perpendicular to the central axis 14. The attachment channel 161 extends through the end in a direction perpendicular to the extension of the attachment portion 16 and has a preset length, which can be flexibly designed according to actual usage requirements. When connecting a key ring, rope, or hook, the axial direction of the attachment channel 161 is perpendicular to the central axis 14, which allows the pendant 4 to naturally form anti-torsional support after being inserted radially. The preset through length ensures that the contact area between the pendant 4 and the inner wall of the channel is maximized, preventing the hook from rotating or slipping under load. At the same time, the lateral extension direction of the channel is orthogonal to the extension direction of the attachment part 16, so that the hanging force is decomposed into a component parallel to the side wall of the base part, avoiding the bending moment concentration caused by the suspended load on the root of the attachment part 16, solving the problem that traditional lateral hanging holes are prone to structural fatigue fracture, and extending the service life.

[0058] Reference Figure 3 and Figure 5In this embodiment, the protective device for the wireless positioning device 3 further includes a pendant 4, which is inserted through the attachment channel 161. Specifically, the pendant 4 is a key ring, hook, or rope structure adapted to the attachment channel 161, and its diameter or cross-sectional dimensions match the inner diameter of the attachment channel 161. It is inserted through the attachment channel 161 in an interference fit or clearance fit manner. When the pendant 4 is inserted, it is inserted along the axial direction of the attachment channel 161 (perpendicular to the central axis 14), and forms circumferential contact with the inner wall using the preset penetration length of the channel. For example, the metal ring of the key ring can be completely embedded in the channel, and the shank of the hook is tightly fitted to the inner wall of the channel. This design places the connection point between the pendant 4 and the protective device at the end of the attachment portion 16, with the load direction perpendicular to the central axis 14. This effectively disperses the gravity or tension of the wireless positioning device 3 when it is suspended. When the gravity of the pendant 4 is transmitted to the attachment portion 16 through the attachment channel 161, the load is decomposed into a horizontal component along the side wall of the base portion because the channel axis is perpendicular to the central axis 14. This avoids generating a vertical bending moment at the root of the attachment portion 16, reducing the risk of structural fatigue fracture. At the same time, the tight contact between the pendant 4 and the channel prevents the pendant 4 from rotating or slipping during use, making it particularly suitable for high-frequency attachment scenarios such as keys and backpacks. The pendant 4 can be made of metal, plastic, or elastic rope, and its surface can be equipped with anti-slip textures or barbed structures to further enhance the reliability of the connection with the attachment channel 161. This allows the protective device to be waterproof and sealed while also being conveniently carried and secured through the pendant 4, meeting diverse user needs.

[0059] In one embodiment, the first base portion 11, the second base portion 12, the cover 2, and the window 112 are all radially symmetrical about the central axis. Specifically, the first base portion 11, the second base portion 12, the cover 2, and the window 112 are all radially symmetrical about the central axis 14, that is, the outline, sidewall thickness, opening position, and functional structure (such as the enclosure portion 111, the annular positioning step 114, the annular groove 21, the annular protrusion 113, the positioning groove 23, etc.) of each component are all radially and uniformly distributed along the central axis 14, forming regular geometric shapes such as circles and regular polygons. This radially symmetrical design ensures structural consistency across any radial cross-section of the protective device. When the wireless positioning device 3 is installed and subjected to compressive or external impact forces, the load can be uniformly transmitted along the central axis 14 to the first and second base parts 12 and the cover 2, avoiding localized stress concentration caused by structural offset and significantly improving the overall structural strength. Simultaneously, the symmetrical window 112 and the edge of the cover 2 ensure uniform circumferential sealing pressure distribution between the inner wall of the enclosure part 111 and the upper surface of the cover 2, maintaining consistent liquid penetration resistance in all directions and enhancing the reliability of waterproofing performance. Furthermore, the radially symmetrical geometry eliminates the need to differentiate angles during assembly; quick alignment can be achieved through positioning along the central axis 14, improving production efficiency. It also precisely adapts to circular or near-circular wireless positioning devices 3 (such as AirTag), reducing shaking or offset after installation through symmetrical support surfaces, providing a stable sealing and protective foundation for the internal space 13.

[0060] Reference Figure 3 In one embodiment, the internal space 13 is a flattened sphere. Specifically, the internal space 13 is a flattened sphere with an ellipsoidal shape in which the minor axis is perpendicular to the central axis 14 and the major axis extends radially, adapting to the flattened circular shape of the wireless positioning device 3 (such as AirTag). This spatial design allows the device to form a curved fit with the inner walls of the first and second base parts 12 after installation, reducing assembly gaps while ensuring that the compressive force generated by the device is evenly distributed along the flattened spherical surface. This drives the upper surface edge of the cover 2 to fit more tightly with the inner wall of the enclosure part 111, further improving waterproof performance from a spatial geometry perspective and ensuring that the device obtains stable support and reliable protection in a confined space.

[0061] In one embodiment, the protective element 1 is integrally molded. Specifically, the protective element 1 is manufactured using an integral injection molding process, and the first base portion 11 and the second base portion 12 can be connected into a seamless whole using silicone or TPU materials. Compared to the traditional split protective sleeves with assembly seams, the protective element 1 in this embodiment is integrally molded, forming a seamless overall structure, significantly improving structural strength and sealing reliability, and facilitating assembly.

[0062] In one embodiment, the protective element 1 is a flexible structure. Specifically, the protective element 1 can be made of elastic materials such as silicone or TPU to form a flexible structure, which can undergo elastic deformation as a whole. This flexibility allows the enclosure portion 111 of the first base portion 11 to expand outward elastically when the cover 2 and the wireless positioning device 3 are assembled, making it easy for both to be easily inserted into the internal space 13 through the window 112. After installation, the restoring force of the flexible material causes the inner wall of the enclosure portion 111 to fit tightly against the edge of the upper surface of the cover 2. While achieving convenient assembly, the elastic compression of the material itself further eliminates gaps, enhances the reliability of the surface contact seal, and improves waterproof performance.

[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
