[0002] Currently, most anti-loss devices on the market (such as Bluetooth trackers and GPS anti-loss devices) use adhesive bonding to fix the bottom shell and the front panel. While this method is low-cost and simple, it has the following drawbacks:

[0003] Adhesive bonding processes are difficult to apply evenly, and localized gaps can create channels for water seepage, especially in humid or dusty environments. Furthermore, adhesive bonding relies on the adhesive strength, making the casing prone to cracking or separation due to impact during drops or collisions, thus reducing product durability. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a housing assembly and anti-loss device that can improve the bonding strength and sealing effect between the bottom shell and the panel.

[0005] This application provides the following technical solution:

[0006] In a first aspect, embodiments of this application provide a housing assembly, the housing assembly comprising:

[0007] The bottom shell has an open end and a liquid collection tank. The end face of the open end has an annular insertion groove and an opening, and the opening is located in the area enclosed by the insertion groove. The insertion groove is used to contain adhesive liquid, and the liquid collection tank and the insertion groove are connected.

[0008] The panel has an annular insertion portion on one end face, and the insertion portion passes through the insertion slot.

[0009] In some embodiments of the first aspect, a flow gap is formed between the end of the plug and the bottom of the plug groove, and the flow gap is connected to the liquid collection tank.

[0010] In some embodiments of the first aspect, a retaining engagement is formed between the plug portion and the groove wall of the plug groove.

[0011] In some embodiments of the first aspect, the two walls of the insertion slot fully abut against the corresponding side walls of the insertion portion.

[0012] In some embodiments of the first aspect, a plurality of communication points are defined between the liquid collection tank and the insertion slot, at least some of the plurality of communication points being spaced apart in the extension direction of the insertion slot;

[0013] And / or, the connection point between the liquid collection tank and the insertion slot is located on the wall of the insertion slot.

[0014] In some embodiments of the first aspect, the liquid collection tank is disposed on the end face of the open end, and the opening of the liquid collection tank is located within the coverage area of ​​the panel, such that the panel can close the opening of the liquid collection tank.

[0015] In some embodiments of the first aspect, the bottom shell has a button and a button hole, the button is located in the button hole, and the periphery of the button is an elastic abutment portion, the elastic abutment portion and the periphery inner wall of the button hole are in abutting and sealing fit;

[0016] And / or, the panel has a button and a button hole, the button is located in the button hole, the periphery of the button is an elastic abutment, and the elastic abutment and the inner wall of the periphery of the button hole are in abutting and sealing fit.

[0017] In some embodiments of the first aspect, the bottom housing has a light-transmitting portion for transmitting light emitted by a light source assembly within the housing assembly; wherein the light-transmitting portion includes a light guide, the bottom housing has a window, the light guide is disposed at the window, and the light guide is used to seal the window.

[0018] Secondly, this application also provides an anti-loss device, which includes a housing assembly as described in any of the above embodiments.

[0019] In some embodiments of the second aspect, the anti-loss device further includes a pull ring assembly and an alarm assembly, the pull ring assembly and the housing assembly being quick-release connected, and the alarm assembly being disposed within the housing assembly; wherein the pull ring assembly has an alarm triggering part, and the alarm assembly has a detection part, the alarm triggering part and the detection part correspondingly cooperating, the alarm triggering part passing through a mounting hole on the housing assembly, and the alarm triggering part abutting against the detection part; when the alarm triggering part is disengaged from the detection part, the alarm assembly is triggered to operate; wherein the alarm triggering part and the mounting hole are dynamically sealed.

[0020] The embodiments of this application have the following advantages:

[0021] This application provides a housing assembly. The open end of the bottom shell has an annular insertion groove, and the panel has a corresponding annular insertion part. The two are mechanically fitted together by insertion. Adhesive is pre-injected into the insertion groove. After the insertion part is inserted, the adhesive evenly fills the gap, forming a double fixation, namely mechanical fixation and adhesive fixation. A collection tank is connected to the insertion groove. During the insertion of the insertion part into the groove, the adhesive is squeezed by the insertion part, allowing it to flow along the groove and enter the collection tank. The collection tank collects excess adhesive, preventing adhesive from contaminating the panel or bottom shell surface. It also ensures an appropriate amount of adhesive in the insertion groove and even distribution of the adhesive within the groove, reducing dead zones and improving bonding uniformity and strength.

[0022] Furthermore, the annular design of the insertion groove creates a continuous sealing ring for the adhesive, blocking all potential water seepage paths; the tight fit between the insertion part and the groove wall further prevents moisture or dust from entering. The mechanical insertion structure disperses external impact forces, reducing the stress borne by the adhesive layer alone, and preventing the shell from cracking or separating upon drop.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] In related technologies, commercially available anti-loss devices (such as Bluetooth trackers and GPS anti-loss devices) generally use adhesive bonding to fix the bottom shell and panel. While this method is low-cost and simple, it has the following drawbacks: adhesive bonding makes it difficult to achieve uniform bonding pressure, and local gaps may form water seepage channels, especially in humid or dusty environments. Furthermore, adhesive bonding relies on the adhesive strength, and the shell is prone to cracking or separation due to impact during drops or collisions, reducing product durability.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to solve the above-mentioned technical problems, this application provides a housing assembly 100, which includes a bottom shell 110 and a panel 120. The bottom shell 110 has an open end and a liquid collection tank 115. The end face of the open end has an annular insertion groove 113 and an opening, which is located in the area enclosed by the insertion groove 113. The insertion groove 113 is used to contain adhesive liquid, and the liquid collection tank 115 and the insertion groove 113 are connected. One end face of the panel 120 has an annular insertion portion 121, which passes through the insertion groove 113.

[0039] In these embodiments, this application provides an improved housing assembly 100 designed to enhance the adhesive strength and sealing effect between the bottom shell 110 and the panel 120 of devices such as anti-loss devices. The bottom shell 110 has an open end, and an annular insertion groove 113 and an opening are provided on the end face of this open end. The opening is located within the area enclosed by the insertion groove 113 and communicates with the inner cavity of the bottom shell 110 to facilitate the installation of electronic components, such as a warning component 500, a light source component 400, or a power supply component, within the inner cavity of the bottom shell 110. Notably, the bottom shell 110 is also equipped with a liquid collection tank 115, which communicates with the insertion groove 113, for containing excess adhesive. It can be understood that the pressure at the connection between the insertion groove 113 and the liquid collection tank 115 is relatively low, creating a tendency for the adhesive in the insertion groove 113 to flow into the liquid collection tank 115.

[0040] One end face of panel 120 is provided with an annular insertion portion 121, which can pass through the insertion groove 113 of bottom shell 110. That is, the shape and size of insertion portion 121 and insertion groove 113 are adapted to each other, so that insertion portion 121 can be inserted into insertion groove 113. It should be noted that panel 120 covers the opening end to close the opening. The cooperation between insertion portion 121 and insertion groove 113 also facilitates the positioning of panel 120 and opening end. For example, to improve the aesthetics of the connection between panel 120 and opening end, the end face of panel 120 fits the opening end, eliminating the gap between them and improving the overall integrity of housing assembly 100.

[0041] For example, in one embodiment, recessed areas are provided on both sides of the insertion portion 121 to accommodate overflowing adhesive. Of course, in other embodiments, the opening of the insertion groove 113 can also be set as an flared shape, which is conducive to filling the adhesive and also facilitates the insertion portion 121 into the insertion groove 113.

[0042] Therefore, the open end of the bottom shell 110 is provided with an annular insertion groove 113, and the panel 120 is correspondingly designed with an annular insertion part 121. The two are mechanically fitted together by insertion. Adhesive is pre-injected into the insertion groove 113. After the insertion part 121 is inserted, the adhesive evenly fills the gap, forming a double fixation, namely mechanical fixation and adhesive fixation. The liquid collection tank 115 is connected to the insertion groove 113. During the insertion of the insertion part 121 into the insertion groove 113, the adhesive is squeezed by the insertion part 121, allowing it to flow along the insertion groove 113 and enter the liquid collection tank 115. The liquid collection tank 115 accommodates the excess adhesive, which not only prevents the adhesive from contaminating the surface of the panel 120 or the bottom shell 110, but also ensures that the amount of adhesive in the insertion groove 113 is appropriate and that the adhesive is evenly distributed in the insertion groove 113, reducing the dead corners of the adhesive filling in the insertion groove 113 and improving the uniformity and strength of the adhesion.

[0043] Furthermore, the annular design of the insertion groove 113 allows the adhesive to form a continuous sealing ring, sealing off all potential water seepage paths; the tight fit between the insertion part 121 and the groove wall further prevents moisture or dust from entering. The mechanical insertion structure disperses external impact forces, reduces the stress borne by the adhesive layer alone, and prevents the shell from cracking or separating upon drop.

[0044] like Figure 2 As shown, in some embodiments, a flow gap is formed between the end of the insertion part 121 and the bottom of the insertion groove 113, and the flow gap is connected to the liquid collection tank 115.

[0045] In these embodiments, by providing a flow gap, when the insertion portion 121 of the panel 120 is inserted into the insertion groove 113 of the base shell 110, the adhesive can flow freely within the gap, ensuring that the adhesive can be more evenly distributed within the insertion groove 113. This helps reduce dead zones in the filling process, resulting in a stronger and more uniform bond.

[0046] The design of the flow gap communicating with the collection tank 115 defines the flow direction of the adhesive liquid; for example, the adhesive flows in one direction. This allows excess adhesive that overflows due to compression during the insertion process to flow smoothly into the collection tank 115. This mechanism not only avoids the problem of adhesive overflow and contamination of the panel 120 or the bottom shell 110 surface, but also ensures that the amount of adhesive in the insertion groove 113 is moderate, which is beneficial to improving the bonding effect.

[0047] Furthermore, the presence of flow gaps ensures that the adhesive can fully cover all potential water seepage paths, forming an effective waterproof barrier. In addition, the tight fit between the insertion part 121 and the wall of the insertion groove 113 effectively prevents the intrusion of moisture and dust.

[0048] Furthermore, the flow gap provides additional space for the insertion part 121, which to some extent increases the tolerance during the assembly process, reduces the requirements for precision, and makes the assembly process more flexible and convenient.

[0049] For example, in one embodiment, the cross-section of the plug portion 121 is triangular, and the cross-section of the plug groove 113 may also be triangular. Of course, in other embodiments, the cross-section of the plug portion 121 is square, and the cross-section of the plug groove 113 may also be semi-circular. Alternatively, the cross-section of the plug portion 121 may be triangular, and the cross-section of the plug groove 113 may also be semi-circular.

[0050] like Figure 2 As shown, in some embodiments, a retaining engagement is formed between the insertion portion 121 and the groove wall of the insertion slot 113.

[0051] In these embodiments, the insertion portion 121 and the groove wall of the insertion slot 113 are configured to form a locking engagement. This further enhances the stability and reliability of the connection between the bottom shell 110 and the panel 120, with the following specific advantages:

[0052] Through a locking mechanism, the insertion part 121 can be firmly locked onto the groove wall after being inserted into the insertion groove 113, increasing the strength of the mechanical engagement. This physical locking mechanism can effectively disperse externally applied forces, reduce reliance on adhesive alone, and lower the risk of shell cracking or separation due to drops or impacts.

[0053] The design of the locking mechanism requires high manufacturing precision for the insertion part 121 and the insertion slot 113, which helps ensure that the two can fit together accurately. Precise assembly not only improves the overall quality of the product, but also ensures that the adhesive is evenly distributed, optimizing the sealing effect.

[0054] Although higher manufacturing precision is required, the snap-fit ​​design makes the installation process more intuitive and simple. Users or assemblers can initially secure the base shell 110 to the panel 120 with a simple insertion operation.

[0055] Clearly, in addition to the mechanical reinforcement, the clamping fit provides an extra layer of sealing. The tightly fitting insertion part 121 and the groove wall prevent moisture and dust from entering the device, providing better protection for the product.

[0056] For example, the engagement between the connector 121 and the slot 113 can be achieved using a resilient snap-fit ​​design. Small snap-fits made of a resilient material are provided on the walls of the connector 121 or the slot 113. When the panel 120 is inserted into the base shell 110, these snap-fits temporarily deform under pressure, allowing the connector 121 to smoothly enter the slot 113. Once the desired position is reached, the snap-fits return to their original shape and lock into specific grooves or protrusions on the connector 121, forming a secure engagement.

[0057] Alternatively, the locking engagement between the insertion part 121 and the insertion slot 113 can employ a wedge-shaped structure design. A wedge-shaped structure is designed on one of the walls of the insertion part 121 and the insertion slot 113. This structure gradually increases the contact area during insertion and creates a "locking" effect through the interaction between the inclined surfaces, enhancing the mechanical fixation strength. The wedge-shaped structure design must ensure that it can withstand a certain amount of external force without easily loosening.

[0058] Alternatively, an interference fit can be used for the engagement between the connector 121 and the slot 113. By precisely controlling the size of the connector 121 to be slightly larger than the size of the slot 113, a tight fit is achieved by utilizing the elasticity and compressibility of the material. This interference fit method does not require additional clips or other mechanical parts, relying on the inherent properties of the material to achieve a stable connection.

[0059] Alternatively, a multi-point locking mechanism can be used for the locking engagement of the connector 121 and the slot 113. Multiple small locking points are designed on the wall of the connector 121 or the slot 113. These locking points can lock sequentially with corresponding parts on the other component during insertion, forming multiple independent but cooperative fixing points, thereby improving the overall stability and impact resistance.

[0060] In some embodiments, the two walls of the insertion slot 113 are fully in contact with the corresponding side walls on the insertion part 121.

[0061] In these embodiments, the two walls of the insertion groove 113 fully abut against the corresponding side walls of the insertion portion 121. Full abutment means that the contact area between the groove wall of the insertion groove 113 and the side wall of the insertion portion 121 is maximized. This not only increases the holding contact area and improves the connection strength, but also significantly enhances the flowability of the adhesive forced by the insertion portion 121, allowing the adhesive to be distributed more evenly throughout the insertion area, reducing weak points in the bond caused by insufficient or uneven distribution of adhesive. Because the groove wall of the insertion groove 113 fully abuts against the side wall of the insertion portion 121, the adhesive is confined to a fixed area, avoiding unnecessary overflow or waste. This not only improves the utilization rate of the adhesive but also reduces the workload of cleaning up excess adhesive.

[0062] Furthermore, the fully abutting design ensures a tight fit between the insertion part 121 and the groove wall of the insertion slot 113, effectively preventing the intrusion of external pollutants such as moisture and dust. This tight fit, combined with the sealing effect of the adhesive, forms a more reliable waterproof and dustproof barrier, making it particularly suitable for use in humid or dusty environments.

[0063] Clearly, with the groove wall of the insertion slot 113 fully abutting against the side wall of the insertion part 121, the contact surface between them can withstand greater external impact forces. Even in the event of a drop or collision, the increased contact area disperses stress, reducing the risk of excessive localized stress. This design reduces the likelihood of the adhesive layer bearing stress alone, thereby further improving the product's durability.

[0064] Of course, a full fit usually requires high manufacturing precision, but it also reduces the requirements for operators during assembly. Since the insertion part 121 and the groove wall of the insertion slot 113 are fully fitted, there is no need to worry about angular deviation or positional offset during insertion, simplifying the assembly process.

[0065] like Figure 3 As shown, in some embodiments, a plurality of connecting points 114 are defined between the liquid collection tank 115 and the insertion slot 113, and at least some of the connecting points 114 are spaced apart in the extending direction of the insertion slot 113.

[0066] In these embodiments, a plurality of communication points 114 are defined between the collection tank 115 and the insertion slot 113, and at least some of these communication points 114 are spaced apart in the extending direction of the insertion slot 113. This further optimizes the flow and distribution of the adhesive, while improving the overall performance of the housing assembly 100.

[0067] Multiple connection points 114 allow the adhesive to flow into the collection tank 115 through different locations, thereby optimizing the flow path of the adhesive within the insertion groove 113. The spaced-apart connection points 114 enable the adhesive to be more evenly distributed in different areas of the insertion groove 113, reducing uneven filling problems caused by excessive or insufficient adhesive in certain areas.

[0068] During the insertion of the connector 121 into the connector groove 113, the adhesive flows along the connector groove 113 due to the squeezing action. The presence of multiple connecting points 114 guides the adhesive from different positions into the collection tank 115, preventing the adhesive from concentrating in a certain area. This uniformly distributed design ensures consistent bonding strength and reduces the occurrence of weak points in the bond.

[0069] If there is only one connection point 114, the flow of adhesive may be affected by excessive adhesive or blockage by impurities. The design with multiple connection points 114 provides redundant paths, ensuring that even if one connection point 114 becomes blocked, the other connection points 114 can still guarantee the smooth flow of adhesive into the collection tank 115. This design improves the reliability of the assembly process and reduces quality problems caused by obstructed adhesive flow.

[0070] In particular, for complex-shaped or long insertion slots 113, a single connection point 114 may not be sufficient to ensure uniform adhesive distribution. Multiple connection points 114 can be segmented along the extension direction of the insertion slot 113 to ensure that the adhesive can cover the entire area of ​​the insertion slot 113. This design is particularly suitable for annular insertion slots 113 or other applications requiring large-area bonding.

[0071] Furthermore, the design of multiple connection points 114 allows excess adhesive to flow quickly into the collection tank 115, preventing adhesive from accumulating in the insertion slot 113 or overflowing onto the surface of the panel 120 or the bottom shell 110. This not only maintains the product's clean appearance but also reduces the workload of cleaning excess adhesive, improving production efficiency.

[0072] like Figure 3 As shown, in some embodiments, the connection point 114 between the liquid collection tank 115 and the insertion slot 113 is located on the wall of the insertion slot 113.

[0073] In these embodiments, by setting the connection point 114 on the tank wall, the flow path and distribution effect of the adhesive are further optimized, while the overall performance of the housing assembly 100 is improved.

[0074] When the connection point 114 is located on the wall of the insertion groove 113, the adhesive can flow directly from the insertion groove 113 into the collection tank 115, reducing the resistance and path complexity of the adhesive during the flow process. This allows the adhesive to be guided into the collection tank 115 faster and more efficiently, avoiding adhesive accumulation or uneven distribution caused by excessively long flow paths.

[0075] Since the connection point 114 is located on the tank wall, excess adhesive can flow directly from the side wall of the insertion slot 113 into the collection tank 115, avoiding the accumulation or waste of adhesive at the bottom of the insertion slot 113.

[0076] This design improves the utilization rate of adhesive, reduces material waste, and ensures that the amount of adhesive in the insertion slot 113 is appropriate, neither too much nor too little.

[0077] For insertion grooves 113 of different shapes or sizes, such as annular or rectangular, the connecting points 114 on the groove wall can be flexibly arranged according to specific needs, making them more adaptable. Especially in annular insertion grooves 113, the connecting points 114 on the groove wall can be evenly distributed, ensuring that the adhesive flows smoothly and is evenly distributed throughout the insertion groove 113.

[0078] For example, the depth of the bottom of the insertion slot 113 can also gradually increase in the direction close to the connection point 114, serving a guiding function.

[0079] like Figure 3 As shown, in some embodiments, the liquid collection tank 115 is disposed on the end face of the open end, and the opening of the liquid collection tank 115 is located within the coverage area of ​​the panel 120, so that the panel 120 can close the opening of the liquid collection tank 115.

[0080] In these embodiments, when the panel 120 closes the opening of the liquid collection tank 115, it not only provides a sealing function but also provides additional support for the entire structure, increasing the stability of the connection between the bottom shell 110 and the panel 120.

[0081] Excess adhesive can be squeezed into the collection tank 115 through the plug part 121, and the closed opening of the panel 120 ensures that the adhesive will not overflow to the outside of the equipment. The adhesive stored in the collection tank 115 will contact and bond the part of the panel 120 located in the collection tank 115, further improving the connection strength.

[0082] like Figure 2 and Figure 5 As shown, in some embodiments, the bottom shell 110 has a button 200 and a button hole 116. The button 200 is located inside the button hole, and the periphery of the button 200 is an elastic abutment portion 210. The elastic abutment portion 210 and the periphery inner wall of the button hole are in abutting and sealing fit.

[0083] In these embodiments, the bottom shell 110 has a button 200 and a button hole 116, wherein the button 200 is located inside the button hole 116, and an elastic abutment portion 210 is provided extending from the periphery of the button 200, that is, the elastic abutment portions 210 are joined end to end to form a ring structure. The abutment and sealing fit between the elastic abutment portion 210 and the inner periphery of the button hole achieves the following advantages:

[0084] The design of the elastic contact part 210 can ensure an effective seal around the button 200, preventing external contaminants such as moisture and dust from entering the device through the button hole 116.

[0085] The abutment made of elastic material provides appropriate feedback force when the button 200 is pressed, making the user's pressing operation more comfortable and intuitive. It also helps the button 200 return to its original position, ensuring that the button 200 accurately resets after each press, improving reliability.

[0086] The resilient contact portion 210 not only serves a sealing function but also provides additional support for the button 200, enhancing its overall structural stability. During frequent use, it effectively reduces operational malfunctions caused by button 200 shaking or loosening. Compared to traditional complex sealing structures, the design using the resilient contact portion 210 is relatively simple and easy to implement, helping to reduce production costs and process complexity.

[0087] In addition, this design reduces the requirements for precision assembly, making the production and assembly process more efficient.

[0088] For example, the button 200 is made entirely of an elastic material, such as silicone or rubber. The button 200 can be cylindrical in shape, and the button hole 116 can be a circular hole; the two are interference-fitted, and a seal is achieved through elastic deformation.

[0089] In some embodiments, the panel 120 has a button 200 and a button hole 116. The button 200 is located inside the button hole, and the periphery of the button 200 is an elastic abutment portion 210. The elastic abutment portion 210 and the inner wall of the periphery of the button hole are in abutting and sealing fit.

[0090] In these embodiments, the panel 120 has a button 200 and a button hole 116, wherein the button 200 is located within the button hole 116, and a resilient abutment portion 210 is provided on the periphery of the button 200. This design achieves the following advantages through the abutting and sealing fit between the resilient abutment portion 210 and the inner wall of the periphery of the button hole:

[0091] The design of the elastic contact part 210 can ensure an effective seal around the button 200, preventing external contaminants such as moisture and dust from entering the device through the button hole 116.

[0092] The abutment made of elastic material provides appropriate feedback force when the button 200 is pressed, making the user's pressing operation more comfortable and intuitive. It also helps the button 200 return to its original position, ensuring that the button 200 accurately resets after each press, improving reliability.

[0093] The resilient contact portion 210 not only serves a sealing function but also provides additional support for the button 200, enhancing its overall structural stability. During frequent use, it effectively reduces operational malfunctions caused by button 200 shaking or loosening. Compared to traditional complex sealing structures, the design using the resilient contact portion 210 is relatively simple and easy to implement, helping to reduce production costs and process complexity.

[0094] In addition, this design reduces the requirements for precision assembly, making the production and assembly process more efficient.

[0095] For example, the button 200 is made entirely of an elastic material, such as silicone or rubber. The button 200 can be cylindrical in shape, and the button hole 116 can be a circular hole; the two are interference-fitted, and a seal is achieved through elastic deformation.

[0096] It should be noted that the opening of the button hole 116 is provided with a limiting part to limit the elastic abutment part 210 and prevent the button 200 from disengaging from the button hole 116. For example, the diameter of the opening is smaller than the outer diameter of the elastic abutment part 210, thereby achieving blocking and limiting.

[0097] like Figure 2 and Figure 3 As shown, in some embodiments, the bottom shell 110 has a light-transmitting portion for transmitting light emitted by the light source assembly 400 inside the outer shell assembly 100; wherein, the light-transmitting portion includes a light guide 112, the bottom shell 110 has a window 111, the light guide 112 is disposed at the window 111, and the light guide 112 is used to seal the window 111.

[0098] In these embodiments, the bottom shell 110 has a light-transmitting portion for transmitting light emitted by the light source assembly 400 within the outer shell assembly 100. Specifically, the light-transmitting portion includes a light guide 112, which is disposed at the window 111 of the bottom shell 110 and is used to seal the window 111.

[0099] The light guide 112 effectively guides the light emitted by the light source assembly 400 into the external environment, ensuring that the light can penetrate the housing with minimal loss. It is suitable for devices requiring indicator lights, illumination, or other forms of visual feedback, such as status indicators and alarm signals for electronic devices.

[0100] The light guide 112 not only transmits light but also seals the window 111, preventing moisture and dust from entering the device. Using materials with excellent sealing properties to make the light guide 112 ensures reliable protection while maintaining optical performance, making it particularly suitable for outdoor or harsh environments.

[0101] For example, the light guide 112 and the base shell 110 are fused together using the fusion properties of plastics through two-color injection molding or secondary molding, achieving a fusion connection between the two plastic materials. Of course, in other embodiments, the light guide 112 and the base shell 110 are bonded and sealed together.

[0102] like Figure 1 and Figure 2 As shown, in some embodiments, this application also provides an anti-loss device, which includes a housing assembly 100 as described in any of the above embodiments.

[0103] Since the aforementioned housing assembly 100 has the above-mentioned technical effects, the anti-loss device including the housing assembly 100 should have the same technical effects, which will not be elaborated here.

[0104] For example, the anti-loss device can be a Bluetooth tracker, a GPS anti-loss device, a WiFi anti-loss device, or a multi-functional anti-loss device, etc.

[0105] like Figure 2 As shown, in some embodiments, the anti-loss device further includes a pull ring assembly 300 and an alarm assembly 500. The pull ring assembly 300 is quickly connected to the housing assembly 100, and the alarm assembly 500 is disposed inside the housing assembly 100. The pull ring assembly 300 has an alarm triggering part 310, and the alarm assembly 500 has a detection part. The alarm triggering part 310 and the detection part cooperate correspondingly. The alarm triggering part 310 passes through a mounting hole on the housing assembly 100, causing the alarm triggering part 310 to abut against the detection part. When the alarm triggering part 310 is disengaged from the detection part, the alarm assembly 500 is triggered to operate. A dynamic seal is formed between the alarm triggering part 310 and the mounting hole.

[0106] In these embodiments, the pull ring assembly 300 is connected to the housing assembly 100 via a quick-release connection, which facilitates quick installation or removal of the housing assembly 100 by the user and increases ease of use.

[0107] The pull ring assembly 300 includes an alarm trigger 310, while the warning assembly 500 is equipped with a corresponding detection unit. The two are precisely designed to achieve a mating fit.

[0108] When the pull ring assembly 300 remains connected, the alarm triggering unit 310 and the detection unit are in contact. Once the pull ring is forcibly removed (e.g., when items are stolen or personal safety is threatened), the alarm triggering unit 310 disengages from the detection unit and immediately triggers the warning assembly 500 to issue an alarm.

[0109] The alarm trigger 310 passes through a mounting hole on the housing assembly 100 and forms a dynamic seal with it. This design ensures that even under dynamic use, external substances such as moisture and dust can be effectively prevented from entering the equipment, enhancing its overall waterproof and dustproof performance. The dynamic seal not only ensures the normal operation of the equipment but also extends its service life.

[0110] For example, the alarm triggering part 310 is provided with a groove, and an elastic sealing ring 320 is installed in the groove. The elastic sealing ring 320 abuts against the inner wall of the mounting hole and deforms to achieve dynamic sealing.

[0111] When the alarm triggering unit 310 is disconnected from the detection unit, the warning component 500 will automatically activate the alarm program, which includes sound alarm and vibration reminder.

[0112] For example, the detection unit may be a micro switch, a photoelectric sensor, a position sensor, a Hall effect sensor, or a pressure sensor, etc.

[0115] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
