Description

Technical Field

[0001] This utility model particularly relates to an easy-to-disassemble waterproof anti-loss device. Background Technology

[0002] With the development of IoT technology, small electronic devices such as anti-loss devices and GPS trackers are becoming increasingly popular. These devices typically need to be waterproof to withstand outdoor use, and also require easy disassembly for battery replacement or internal module maintenance.

[0003] In existing technologies, the methods for fixing positioning modules mainly have the following problems:

[0004] Mechanical fasteners are not secure:

[0005] Traditional solutions often use simple clips or adhesives to fix the positioning module. For example, the positioning module is only fixed by plastic clips around the perimeter, which can easily shift or even fall off when subjected to vibration or impact.

[0006] Lack of multiple positioning:

[0007] Most existing housings only provide positioning in one direction. While a bottom support structure inside the housing can prevent the module from sinking, it cannot effectively limit horizontal displacement. In practical use, this structure can cause the module to sway during movement, affecting the reliability of the equipment.

[0008] No continuous compression mechanism:

[0009] While common waterproof housings achieve a seal through rotational locking, they do not provide continuous clamping force to the internal positioning module. Over time, fretting wear may cause poor contact between the module and the contacts.

[0010] In summary, existing electronic device housings generally suffer from technical defects in fixing positioning modules, such as insecure fixing, lack of multiple positioning, and lack of continuous clamping. There is an urgent need for an innovative structure that can solve these problems simultaneously. Utility Model Content

[0011] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an easy-to-disassemble waterproof anti-loss device.

[0012] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0013] An easily detachable and waterproof anti-loss device includes an upper shell and a lower shell, which are detachably connected by a rotary locking mechanism. The lower shell contains a mounting structure for a positioning module, which includes a support portion and at least two positioning posts. The support portion supports the bottom surface of the positioning module, and the positioning posts pass through through holes in the positioning module to achieve lateral positioning. The inner side of the upper shell has a downwardly extending clamping portion. When the upper shell rotates relative to the lower shell to the locked position, the clamping portion presses against the upper surface of the positioning module, clamping and fixing the positioning module between the support portion and the clamping portion.

[0014] Preferably, the rotary locking mechanism includes a limiting groove provided on the inner side wall of the lower housing and a limiting protrusion provided on the inner surface of the upper housing; when the upper housing is rotated to the locked position, the limiting protrusion is engaged in the limiting groove, and at the same time, the pressing part presses against the upper surface of the positioning module, so that the positioning module is three-dimensionally fixed between the support part, the positioning column and the pressing part.

[0015] Preferably, the outer peripheral wall of the upper housing is provided with an annular mounting groove, and a sealing ring is embedded in the annular mounting groove; when the upper housing is rotated to the locked position, the sealing ring is compressed between the mating surfaces of the upper housing and the lower housing.

[0016] Preferably, the upper end face of the lower housing is recessed inward to form an annular mounting platform. When the upper housing is rotated to the locked position, the lower edge of the upper housing contacts and engages with the upper end face of the annular mounting platform to form an axial limit.

[0017] Preferably, the inner bottom surface of the lower housing protrudes to form a central support platform, which is used to support the center of the positioning module.

[0018] Preferably, the positioning module includes a charging module and an AirTag module that are electrically connected to each other. The AirTag module has a through hole, and the positioning post passes through the through hole to achieve lateral positioning of the AirTag module. When the upper housing rotates relative to the lower housing to the locked position, the pressing part abuts against the upper surface of the charging module.

[0019] The beneficial effects of this utility model are:

[0020] This utility model's easy-to-install waterproof anti-loss device achieves stable fixation of the positioning module through the unique design of the support part, positioning column, and clamping part, avoiding displacement and loosening during use. At the same time, the ingenious structure of the rotary locking mechanism greatly improves the ease of disassembly and assembly of the shell.

[0032] An easy-to-disassemble waterproof anti-loss device, refer to Figures 1-5 It includes an upper housing 1 and a lower housing 2, which are detachably connected by a rotary locking mechanism; the lower housing 2 is provided with an installation structure for a positioning module 4, which includes a support part 3 and at least two positioning posts 32. The support part 3 is used to support the bottom surface of the positioning module 4, and the positioning posts 32 pass through the through holes 41 opened on the positioning module 4 to achieve lateral positioning.

[0033] The upper housing 1 has a downwardly extending pressing part 12 on its inner side. When the upper housing 1 is rotated relative to the lower housing 2 to the locked position, the pressing part 12 presses against the upper surface of the positioning module 4, so that the positioning module 4 is clamped and fixed between the support part 3 and the pressing part 12.

[0034] Furthermore, the rotary locking mechanism includes a limiting groove 61 disposed on the inner side wall of the lower housing 2 and a limiting protrusion 11 disposed on the inner surface of the upper housing 1; when the upper housing 1 is rotated to the locked position, the limiting protrusion 11 is engaged in the limiting groove 61, and at the same time the pressing part 12 presses the upper surface of the positioning module 4, so that the positioning module 4 is three-dimensionally fixed between the support part 3, the positioning post 32 and the pressing part 12.

[0035] Furthermore, the outer peripheral wall of the upper housing 1 is provided with an annular mounting groove 13, and a sealing ring 5 is embedded in the annular mounting groove 13; when the upper housing 1 is rotated to the locked position, the sealing ring 5 is compressed between the mating surfaces of the upper housing 1 and the lower housing 2.

[0036] Furthermore, the upper end face of the lower housing 2 is recessed inward to form an annular mounting platform 21. When the upper housing 1 is rotated to the locked position, the lower edge 14 of the upper housing 1 contacts and engages with the upper end face of the annular mounting platform 21 to form an axial limit.

[0037] Furthermore, the inner bottom surface of the lower housing 2 protrudes to form a central support platform 22, which is used to support the center of the positioning module 4.

[0038] Furthermore, the positioning module 4 includes a charging module 42 and an AirTag module 43 that are electrically connected to each other. The AirTag module 43 has a through hole 41, and the positioning post 32 passes through the through hole 41 to achieve lateral positioning of the AirTag module 43. When the upper housing 1 rotates relative to the lower housing 2 to the locked position, the pressing part 12 abuts against the upper surface of the charging module 42.

[0039] The working principle of this utility model is as follows:

[0040] The easy-to-install waterproof anti-loss device in this embodiment is mainly used for tracking and preventing loss of items, and has tracking and alarm functions related to the AirTag module.

[0041] The upper housing 1 and lower housing 2 are injection molded from engineering plastic, possessing high strength and good insulation. The rotary locking mechanism design allows for quick and stable connection and disassembly of the upper housing 1 and lower housing 2. A limiting groove 61 is provided on the inner wall of the lower housing 2, and a limiting protrusion 11 is provided on the inner surface of the upper housing 1 to cooperate with it. When assembly is required, the upper housing 1 is aligned with the appropriate position of the lower housing 2, and then the upper housing 1 is rotated, causing the limiting protrusion 11 to gradually enter the limiting groove 61 until it is rotated to the locking position. At this time, the limiting protrusion 11 is completely engaged in the limiting groove 61. At the same time, the pressing part 12 of the upper housing 1 gradually presses down during the rotation, finally pressing against the upper surface of the positioning module 4, firmly clamping and fixing the positioning module 4 between the support part 3, the positioning post 32, and the pressing part 12, achieving three-dimensional fixation and ensuring that the positioning module 4 is stable and reliable during use, without loosening or displacement.

[0042] The annular mounting groove 13 on the outer peripheral wall of the upper housing 1 is fitted with a sealing ring 5. When the upper housing 1 is rotated to the locked position, the sealing ring 5 is squeezed and tightly fits between the joint surfaces of the upper housing 1 and the lower housing 2, forming a good sealing effect and effectively preventing water from entering the housing from the joint gap, thus providing waterproof protection for the positioning module 4.

[0043] The annular mounting platform 21 formed by the inward indentation of the upper end face of the lower shell 2 cooperates with the lower end edge 14 of the upper shell 1 to play an axial limiting role, further enhancing the overall stability of the shell after assembly and preventing axial relative displacement between the upper shell 1 and the lower shell 2 when subjected to external impact.

[0044] The central support platform 22 formed by the protrusion on the bottom surface of the lower housing 2 supports the center of the positioning module 4. Together with the support part 3 and the positioning column 32 in the installation structure, it provides a stable support foundation for the positioning module 4, disperses the stress on the positioning module 4, and ensures its normal operation in various usage environments.

[0045] The specific functions and technical details of positioning module 4:

[0046] The positioning module 4 includes a charging module 42 and an AirTag module 43 that are electrically connected to each other. The main function of the AirTag module 43 is to help users track and locate lost items. By connecting to the user's Apple device, the AirTag can display the location of the item in real time and provide voice guidance to help the user find the item when needed. The design principle of the AirTag module is a mature technology in this field and will not be described in detail here.

[0047] This utility model's easy-to-install waterproof anti-loss device achieves a secure fixation of the positioning module 4 in three-dimensional space through the coordinated action of the support part 3, the positioning post 32, and the clamping part 12 inside the upper shell 1. The support part 3 provides a solid bottom support for the positioning module 4, and the positioning post 32 passes through the through hole 41 on the positioning module 4 to achieve precise lateral positioning, preventing the positioning module 4 from shifting in the horizontal direction. When the upper shell 1 is rotated to the locked position, the pressing action of the clamping part 12 on the upper surface of the positioning module 4 further clamps and fixes the positioning module 4 tightly between the support part 3 and the clamping part 12, effectively preventing the positioning module 4 from loosening or shifting due to external forces such as vibration and collision during use. This stable fixing method ensures good electrical connection and stable signal transmission between the positioning module 4 and the shell, greatly improving the reliability and service life of the anti-loss device in various complex environments.

[0048] The rotary locking mechanism design makes the connection and disassembly of the upper housing 1 and the lower housing 2 extremely simple. Simply rotating the upper housing 1 engages and disengages the limiting protrusion 11 and the limiting groove 61, thus locking and unlocking the housing. This convenient assembly and disassembly method not only facilitates routine maintenance, battery replacement, or repair of the positioning module 4, but also improves assembly efficiency and reduces production costs during manufacturing.

[0049] A sealing ring 5 is embedded in the annular mounting groove 13 on the outer peripheral wall of the upper housing 1. When the upper housing 1 is rotated to the locked position, the sealing ring 5 is compressed between the mating surfaces of the upper housing 1 and the lower housing 2, forming a tight waterproof barrier. Simultaneously, the cooperation between the annular mounting platform 21 of the lower housing 2 and the lower edge 14 of the upper housing 1 further enhances the sealing at the housing joint, effectively preventing water from intruding into the housing from all directions, providing comprehensive waterproof protection for the positioning module 4. This waterproof design allows the anti-loss device to adapt to complex environmental conditions such as humidity, heavy rain, and even short-term immersion, greatly expanding its applicability and improving the product's practicality and durability.

[0050] This utility model's easy-to-install waterproof anti-loss device achieves stable fixation of the positioning module through the unique design of the support part, positioning column, and clamping part, avoiding displacement and loosening during use. At the same time, the ingenious structure of the rotary locking mechanism greatly improves the ease of disassembly and assembly of the shell. Combined with the waterproof design of the sealing ring and annular mounting platform, it comprehensively protects the positioning module from water damage, significantly extending the product's service life. Combined with the advanced AirTag module positioning function, it not only provides users with a stable and reliable personal item tracking solution, but also greatly optimizes the user experience, achieving a comprehensive upgrade in convenience, reliability, and functionality.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
