[0002] In recent years, Bluetooth Low Energy (BLE) based positioning tags, such as AirTag, have been widely used in the field of item tracking due to their miniaturization and high-precision positioning characteristics. Existing technology uses a button battery power supply solution, which has the advantage of a highly integrated internal structure, with the battery compartment and PCB board forming a circuit through flexible metal contacts. However, this design has significant drawbacks in practical applications; limited by the size and capacity of the button battery, the overall battery life of the positioning tag is relatively short.

[0003] To extend the battery life of the positioning tag, the existing technology usually involves directly connecting an external power supply by running wires from the PCB board of the positioning tag. To adapt to the new external power supply, engineers need to redesign the outer shell and internal structure of the positioning tag, which is an extremely complicated process. Therefore, there is an urgent need to find a power supply expander that can extend the battery life of the positioning tag without significantly damaging its original structure.

[0017] Compared with the prior art, the power expansion box and capacity expansion component provided by this utility model have the following advantages:

[0018] 1. A power expansion box provided in this utility model embodiment includes a housing assembly, an anti-loss device, a power assembly and an insulating bracket disposed inside the housing assembly. The anti-loss device is sandwiched between the insulating bracket and the inner wall of the housing assembly. The anti-loss device has a mounting groove on the side near the insulating bracket. A first contact and a second contact are provided at the bottom of the mounting groove. The insulating bracket is adapted to the mounting groove.

[0019] The power supply assembly includes a battery assembly, a first conductive component, and a second conductive component. The battery assembly is disposed on one side of an insulating support. Both the first and second conductive components are disposed on the insulating support.

One end of the second conductive component is connected to the battery assembly, and the other end passes through the insulating support and the first conductive component in sequence and contacts a second contact. In this embodiment, the anti-loss device is sandwiched between the insulating support and the inner wall of the housing assembly. The first and second contacts in its mounting slot directly contact the conductive components on the insulating support, forming a circuit connection. This design allows the power expansion box to be assembled independently without redesigning the original label's PCB or housing; expansion can be completed simply by matching the contacts with the label's battery contacts.

The first conductive component includes a conductive ring and a first conductive contact foot. The first conductive contact foot is disposed on the first support surface and connected to the battery assembly. One end of the first conductive contact foot passes through the first through hole and connects to the conductive ring. The end of the conductive ring away from the support portion contacts the first contact point. The current on the battery assembly flows sequentially through the first conductive contact foot and the conductive ring to the first contact point. The ring structure increases the contact area, ensuring stable surface contact even if the anti-loss device undergoes slight displacement inside the housing, thus avoiding resistance fluctuations caused by point contact.

[0022] 4. In this embodiment of the invention, the second contact is disposed at the bottom of the mounting groove. The second conductive component includes a conductive plate and a second conductive contact.

A first clearance channel is provided on the conductive ring corresponding to the conductive plate. The end of the conductive plate away from the support passes through the first clearance channel and contacts the second contact. The current on the battery assembly flows sequentially through the second conductive contact and the conductive plate to the second contact. This ensures that the two are staggered in the vertical and horizontal directions, preventing direct contact between the conductive ring and the conductive plate.

[0023] 5. The housing assembly of this utility model embodiment includes a first housing, a second housing, and a locking member. The first housing has a locking hole penetrating through it, and the second housing has a locking groove corresponding to the locking hole on the side near the first housing.

The locking member, through the locking hole and engaging with the locking groove, allows the two housings to be quickly locked or separated.

[0024] 6. In this embodiment of the invention, the first housing near the second housing includes a groove wall and a groove bottom. A portion of the groove bottom extends to form a first inner wall. A first gap is left between the first inner wall and the groove wall of the first housing. A first receiving groove is formed on the first inner wall away from the groove wall of the first housing. The first gap can effectively attenuate the force generated during collisions or drops, while the first inner wall can provide secondary protection for the battery assembly and the anti-loss device.

[0026] The second housing includes a groove wall and a groove bottom on the side near the first housing. A portion of the groove bottom of the second housing extends to form a second sealing groove. The second sealing groove is snapped into the first inner wall. A second gap is left between the second sealing groove and the groove wall of the second housing. The locking groove is disposed in the second gap. A second receiving groove is formed in the second sealing groove away from the groove wall of the second housing.

[0027] 8. The battery assembly of this embodiment further includes a first wire and a second wire. One end of the first wire is connected to a first conductive sheet and the other end is connected to a first conductive contact. One end of the second wire is connected to a second conductive sheet and the other end is connected to a second conductive contact.

[0028] 9. In this embodiment of the invention, the battery mounting position and the anti-loss device mounting position are arranged along the length of the housing assembly, and the battery mounting position and the anti-loss device mounting position are flush.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0050] It should be noted that the terms "first" and "second" in the specification and claims of this utility model are used to distinguish different objects, rather than to describe a specific order.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0054] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0055] In recent years, Bluetooth Low Energy (BLE) based positioning tags, such as AirTag, have been widely used in the field of item tracking due to their miniaturization and high-precision positioning characteristics. Existing technology uses a button battery power supply solution, which has the advantage of a highly integrated internal structure, with the battery compartment and PCB board forming a circuit through flexible metal contacts. However, this design has significant drawbacks in practical applications; limited by the size and capacity of the button battery, the overall battery life of the positioning tag is relatively short.

[0056] To extend the battery life of the positioning tag, the existing technology usually involves directly connecting an external power supply by running wires from the PCB board of the positioning tag. To adapt to the new external power supply, engineers need to redesign the outer shell and internal structure of the positioning tag, which is an extremely complicated process. Therefore, there is an urgent need to find a power supply expander that can extend the battery life of the positioning tag without significantly damaging its original structure.

[0057] To solve the above technical problems, please refer to... Figure 1 and Figure 2The first embodiment of this utility model provides a power expansion box 10, which includes a housing assembly 1, an anti-loss device 2, a power assembly 3, and an insulating bracket 4 disposed inside the housing assembly 1. The anti-loss device 2 is sandwiched between the insulating bracket 4 and the inner wall of the housing assembly 1. The anti-loss device 2 has a mounting groove 5 on the side near the insulating bracket 4, and a first contact 51 and a second contact 52 are provided at the bottom of the mounting groove 5. It should be understood that the anti-loss device 2 in this embodiment can be an existing anti-loss module for positioning, such as AirTag, HUAWEI Tag, etc. Existing anti-loss devices 2 usually use button batteries, which, although small in size, limit the battery life of the anti-loss device 2. In this embodiment, the power expansion box 10 can be better adapted to the existing anti-loss device 2. The battery 311 cover of the anti-loss device 2 can be opened and the button battery can be removed. The battery slot in the existing tag for holding the battery 311 is the mounting slot 5 in this embodiment. The first contact 51 and the second contact 52 are the charging contacts in the battery slot of the tag. Furthermore, the insulating bracket 4 is configured to be adapted to the mounting slot 5.

[0058] Furthermore, the power supply assembly 3 includes a battery assembly 31, a first conductive component 32, and a second conductive component 33. It should be noted that a certain distance is maintained between the first conductive component 32 and the second conductive component 33 to prevent them from contacting each other, or an insulating layer is provided between them to prevent short circuits caused by contact. The battery assembly 31 is disposed on one side of the insulating support 4; both the first conductive component 32 and the second conductive component 33 are disposed on the insulating support 4. One end of the first conductive component 32 is connected to the battery assembly 31, and the other end passes through the insulating support 4 to contact the first contact 51. One end of the second conductive component 33 is connected to the battery assembly 31, and the other end passes through the insulating support 4 and the first conductive component 32 in sequence to contact the second contact 52.

[0059] Understandably, in this embodiment, the anti-loss device 2 is sandwiched between the insulating bracket 4 and the inner wall of the housing assembly 1. The first contact 51 and the second contact 52 within its mounting slot 5 directly contact the conductive components on the insulating bracket 4, forming a circuit connection. It should be noted that the power supply assembly 3 supplies power to the anti-loss device 2 through the first conductive component 32 and the second conductive component 33. This design allows the power expansion box 10 to be assembled independently without redesigning the original label's PCB or housing; capacity expansion can be achieved simply by matching the contacts with the label's battery 311 contacts. Furthermore, the contacts of the power supply assembly 3 and the anti-loss device 2 are physically isolated by the insulating bracket 4, avoiding the risk of short circuits. The battery assembly 31 is directly integrated on one side of the insulating bracket 4, further reducing its size and keeping the power expansion box 10 lightweight, adapting to the miniaturized characteristics of the original label. Users only need to insert the battery slot of the anti-loss device 2 between the insulating bracket 4 and the housing assembly 1. Specifically, the first conductive component 32 can contact the first contact 51, and the second conductive component 33 can contact the second contact 52. The contacts automatically complete the circuit connection between the battery component 31 and the anti-loss device 2, thereby improving the battery life. The operation is simple, plug and play, and significantly reduces the complexity of capacity expansion.

[0060] Furthermore, please combine Figure 1 and Figure 3 The insulating bracket 4 includes a connecting part 41 and a supporting part 42 connected to each other. The side of the supporting part 42 away from the mounting groove 5 is a first supporting surface 421. A portion of the first supporting surface 421 extends toward the side closer to the mounting groove 5 to form a groove 422. The end of the groove 422 near the first supporting surface 421 is a second supporting surface 423. The area of ​​the first supporting surface 421 near the groove 422 is provided with a first through hole 424 for the first conductive component 32 to pass through. The second supporting surface 423 is provided with a second through hole 425 for the second conductive component 33 to pass through.

[0061] Understandably, the first perforation 424 and the second perforation 425 are respectively for different conductive components to pass through, avoiding direct contact between conductive components and causing a short circuit in the battery assembly 31. The second support surface 423 of the groove 422 forms a layered contact with the bottom of the mounting groove 5 of the anti-loss device 2, so that when the anti-loss device 2 is clamped between the insulating bracket 4 and the housing assembly 1, the second conductive component 33 can be pressed onto the second contact 52.

[0062] Specifically, the first through hole 424 guides the first conductive component 32 to pass vertically through the insulating bracket 4 and directly contact the first contact 51; the second through hole 425 raises the height of the second conductive component 33 through the groove 422, so that after passing through the clearance channel of the first conductive component 32, it can contact the second contact 52 which is closer to the bottom of the mounting groove 5. The layered through hole design provided in this embodiment solves the problem of wire crossing interference in multi-contact scenarios. At the same time, the designer can design the height of the groove 422 to allow the insulating bracket 4 to adapt to mounting grooves 5 of different depths, thereby improving versatility.

[0063] Furthermore, please combine Figure 1 , Figure 4 and Figure 9 The first contact 51 is located on the side of the bottom of the mounting groove 5 near the groove wall. The first conductive component 32 includes a conductive ring 321 and a first conductive contact 322. The first conductive contact 322 is located on the first support surface 421 and connected to the battery component 31. One end of the first conductive contact 322 passes through the first through hole 424 and is connected to the conductive ring 321. The end of the conductive ring 321 away from the support part 42 contacts the first contact 51.

[0064] It should be understood that the current on the battery assembly 31 flows sequentially through the first conductive contact 322 and the conductive ring 321 to the first contact 51. The conductive ring 321 has a circular design, and its outer circumference is adapted to the wall of the receiving groove, so that the end of the conductive ring 321 contacts the first contact 51 in a ring-shaped manner. It should be understood that the ring structure increases the contact area, so that even if the anti-loss device 2 undergoes slight displacement inside the housing, it can still maintain stable surface contact and avoid resistance fluctuations caused by point contact. In addition, the conductive ring 321 has micro-elasticity to adapt to the dimensional tolerance of the mounting groove 5, reducing the assembly precision requirements and reducing the risk of contact failure due to vibration.

[0065] Furthermore, please combine Figure 1 , Figure 5 and Figure 9 The second contact 52 is located at the bottom of the mounting groove 5. The second conductive component 33 includes a conductive plate 331 and a second conductive contact 332. The second conductive contact 332 is located on the second support surface 423 and connected to the battery assembly 31. One end of the second conductive contact 332 passes through the second through hole 425 and connects to the conductive plate 331. The conductive ring 321 has a first clearance channel 333 corresponding to the conductive plate 331. The end of the conductive plate 331 away from the support part 42 passes through the first clearance channel 333 and contacts the second contact 52.

[0066] It should be understood that the current on the battery assembly 31 flows sequentially through the second conductive contact 332 and the conductive plate 331 to the second contact 51. The conductive plate 331 must pass through the clearance channel of the conductive ring 321 to contact the second contact 52. This design achieves physical isolation between the two levels of contacts through spatial layering: the conductive ring 321 provides clearance channels for the conductive plate 331 to pass through, staggering the two in the vertical and horizontal directions to avoid direct contact between the conductive ring 321 and the conductive plate 331. At the same time, the end of the conductive plate 331 extends to the second contact 52 in a cantilever structure, using elastic deformation to compensate for assembly tolerances. This "through-layer" layout achieves a high-density contact arrangement in a limited space without the need for additional insulating materials, reducing costs.

[0067] Furthermore, please combine Figure 6 , Figure 7 and Figure 8 The housing assembly 1 includes a first housing 11, a second housing 12, and a locking member 13. The first housing 11 has a locking hole 14 extending through it. The second housing 12 has a locking groove 15 corresponding to the locking hole 14 on the side near the first housing 11. The locking member passes through the locking hole 14 and connects with the locking groove 15 to implement a detachable connection between the first housing 11 and the second housing 12. It should be understood that the locking member 13 in this embodiment can be a bolt or a screw. Exemplarily, the locking holes 14 are symmetrically distributed along the length of the housing assembly 1. The locking member 13 passes through the symmetrically distributed locking holes 14 and engages with the locking groove 15, allowing the two housings to be quickly locked or separated.

[0068] It should be understood that by providing the locking element 13, the housing assembly 1 can be disassembled and reassembled non-destructively, allowing users to easily replace the battery 311 or maintain internal components. Furthermore, the first housing 11 and the second housing 12 protect the internal battery assembly 31 and anti-loss device 2, thereby extending the lifespan of the power extension box 10.

[0069] Further, please refer to Figure 6 The side of the first housing 11 near the second housing 12 includes the groove wall and the groove bottom of the first housing 11. A portion of the groove bottom of the first housing 11 extends to form a first inner wall 111. A first gap 112 is left between the first inner wall 111 and the groove wall of the first housing 11. A locking hole 112 is disposed in the first gap 112. A first receiving groove 113 is formed on the first inner wall 111 away from the groove wall of the first housing 11.

[0070] Understandably, the groove wall of the first housing 11 is the outer shell of the first housing 11, and its outer surface is in direct contact with the outside. The first receiving groove 113 is provided with partitions for fixing the battery assembly 31 and the anti-loss device 2, respectively. The first gap 112 ensures that the battery assembly 31 and the anti-loss device 2 are kept at a fixed distance from the outer shell of the housing assembly 1. When the housing assembly 1 is collided or dropped, the first gap 112 can effectively attenuate the force generated by the collision or drop, while the first inner wall 111 can provide secondary protection for the battery assembly 31 and the anti-loss device 2. In addition, the height of the first inner wall 111 can limit the displacement of the battery 311, ensuring its stability in a vibration environment.

[0071] Further, please refer to Figure 7 The side of the second housing 12 near the first housing 11 includes the groove wall and the groove bottom of the second housing 12. A portion of the groove bottom of the second housing 12 extends to form a second sealing groove 121. The second sealing groove 121 is snapped into connection with the first inner wall 111. A second gap 122 is left between the second sealing groove 121 and the groove wall of the second housing 12. A locking groove 115 is disposed in the second gap 122. A second receiving groove 123 is formed in the second sealing groove 121 away from the groove wall of the second housing 12.

[0072] Understandably, the groove wall of the second housing 12 is the outer shell of the second housing 12, and its outer surface is in direct contact with the outside. The second receiving groove 123 also has partitions corresponding to the first receiving groove 113, which respectively cooperate with the first receiving groove 113 to fix the battery assembly 31 and the anti-loss device 2. The second gap 122 ensures that the battery assembly 31 and the anti-loss device 2 are kept at a fixed distance from the outer shell of the housing assembly 1. When the housing assembly 1 is collided or dropped, the second gap 122 can effectively attenuate the force generated during the collision or drop, while the second inner wall can provide secondary protection for the battery assembly 31 and the anti-loss device 2. In addition, this embodiment uses the locking member 13 to fix the first housing 11 and the second housing 12. During the assembly process of the power expansion box 10, the snap-fit ​​connection between the second sealing groove 121 and the first inner wall 111 can also fix the first housing 11 and the second housing 12, thereby improving assembly efficiency.

[0073] It should be noted that the locking hole 112 is located within the first gap 112, and the locking groove 115 is located within the second gap 122. When the first housing and the second housing are installed, the second sealing groove 121 engages with the first inner wall 111. After engagement, the second sealing groove 121 and the first inner wall 111 will create a sealed space inside the housing to prevent the anti-loss device 2 and the power assembly 3 from being lost, and can effectively seal the components within this sealed space, thereby improving the waterproof performance of the sealed space. In addition, neither the locking hole 112 nor the locking groove 115 is located inside this sealed space, and this design will not affect the sealing effect of the sealed space.

[0074] Furthermore, please combine Figure 6 and Figure 8 The first receiving slot 113 includes a battery mounting position 1131 and an anti-loss device mounting position 1132. The second receiving slot 123 is provided with a battery separator plate 1211 corresponding to the battery mounting position 1131. The connecting part 41 has a fixing slot 411. The battery assembly 31 includes a battery 311, a first conductive sheet 312, a second conductive sheet 313 and a third conductive sheet 314. The battery 311 is placed in the battery mounting position 1131. The first conductive sheet 312 and the second conductive sheet 313 are sandwiched between the fixing slot 411 and the battery 311, and there is a distance between the first conductive sheet 312 and the second conductive sheet 313. The third conductive sheet 314 is located at the end of the battery 311 away from the insulating support 4.

[0075] Understandably, the structure of the support portion 42 of the insulating bracket 4 in this embodiment is fully adapted to the mounting slot 5 in the anti-loss device 2, while the structure of the connecting portion 41 of the insulating bracket 4 provides mounting positions for the first conductive sheet 312 and the second conductive sheet 313 in the battery assembly 31. That is, the design of the insulating bracket 4 makes full use of the space inside the housing assembly, and the insulating bracket 4 also acts as a bridge structure, connecting the anti-loss device 2 and the power assembly 3. Furthermore, the distance between the first conductive sheet 312 and the second conductive sheet creates physical isolation, reducing the risk of short circuits.

[0076] It should be noted that the design of the fixing groove 411 on the connecting part 41 provides ample installation space for the first conductive sheet 312 and the second conductive sheet 313. In addition, the distance between the first conductive sheet 312 and the second conductive sheet 313 facilitates heat dissipation and maintenance, allowing users to remove a single conductive sheet without disassembling the entire power supply assembly 3.

[0077] Furthermore, the battery assembly 31 also includes a first conductor 315 and a second conductor 316. One end of the first conductor 315 is connected to the first conductive sheet 312, and the other end is connected to the first conductive contact 322. One end of the second conductor 316 is connected to the second conductive sheet 313, and the other end is connected to the second conductive contact 332. It should be understood that the first conductor 315 and the second conductor 316 are designed with layered wiring to avoid cross-interference. Each conductor has an independent physical channel, reducing the risk of short circuits caused by insulation damage due to friction. In addition, the first conductor 315 and the second conductor 316 can allow a certain degree of deformation to accommodate minor displacements during casing assembly, reducing the risk of wire breakage.

[0078] Furthermore, please combine Figure 1 and Figure 8The battery mounting position 1131 and the anti-loss device mounting position 1132 are arranged along the length of the housing assembly 1, and are flush with each other. It should be understood that this embodiment makes full use of the elongated space inside the housing, avoiding increased thickness due to stacking design. The flush arrangement also ensures a uniform center of gravity distribution, preventing the power box from tipping over due to the weight of the battery 311, thus improving placement stability. Furthermore, the arrangement along the length facilitates standardized production and reduces mold complexity.

[0079] The second embodiment of this utility model provides an expansion component 20, which includes a housing component 201, a power supply component 203, and an insulating bracket 204. It should be understood that the anti-loss device in this embodiment can be the anti-loss module for positioning in the first embodiment, such as AirTag, HUAWEI Tag, etc. Furthermore, the insulating bracket 4 is configured to be adapted to the anti-loss device, and the power supply component 203 is used to supply power to the anti-loss device.

[0080] Furthermore, the power supply assembly 203 includes a battery assembly 2031, a first conductive component 2032, and a second conductive component 2033. Similarly, in this embodiment, a certain distance is maintained between the first conductive component 2032 and the second conductive component 2033 to prevent contact between them, or an insulating layer is provided between them to prevent contact and short circuit. The battery assembly 2031 is disposed on one side of the insulating support 204; both the first conductive component 2032 and the second conductive component 2033 are disposed on the insulating support 204. One end of the first conductive component 2032 is connected to the battery assembly 2031, and the other end passes through the insulating support 204 and is exposed thereout. One end of the second conductive component 2033 is connected to the battery assembly 2031, and the other end passes sequentially through the insulating support 204 and the first conductive component.

[0081] Understandably, in this embodiment, the expansion component 20 can be regarded as the power expansion box 10 in the first embodiment without the anti-loss device. The expansion component 20 has the same beneficial effect as the power expansion box 10, so it will not be described in detail here.

[0082] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
