Description

Technical Field

[0001] This utility model specifically relates to a Bluetooth beacon device. Background Technology

[0002] A Bluetooth beacon is a small device based on Bluetooth technology that transmits information, such as location and timestamps, via broadcast signals. These devices are typically deployed in public places such as shopping malls, museums, and airports to provide indoor positioning services, information push notifications, and navigation. Throughout the development of Bluetooth beacon technology, power supply has been a key factor hindering its widespread adoption. Traditional Bluetooth beacons typically rely on built-in rechargeable or disposable batteries. While this provides mobility and portability, its limitations have become increasingly apparent with technological advancements and the expansion of application scenarios.

[0003] First, battery power presents a significant cost issue. Traditional Bluetooth beacons use built-in batteries, whether rechargeable or disposable. These batteries not only increase the manufacturing cost of the device but also require regular replacement or charging. This increases ongoing maintenance costs and limits the long-term stable operation of the Bluetooth beacon. Especially in large-scale deployment scenarios, the cost and time of battery replacement can increase exponentially, placing a heavy economic burden on businesses or individuals.

[0004] Secondly, battery life and performance are also significant challenges. Batteries have limited capacity and lifespan; as usage time increases, battery capacity gradually decreases, affecting the normal operation and signal transmission quality of the Bluetooth beacon. Therefore, regular battery replacement is necessary to ensure the Bluetooth beacon's proper functioning. However, in many cases, Bluetooth beacons may be installed in hard-to-reach locations, such as at high altitudes, in confined spaces, or in outdoor environments, making battery replacement extremely difficult. Furthermore, frequent battery replacements can interrupt normal Bluetooth beacon service, impacting user experience and system stability. In addition, battery performance is unstable under varying ambient temperatures; extreme temperatures can even cause a sharp decline in battery performance or damage.

[0005] Furthermore, traditional battery power supply limits the flexibility of chip selection for Bluetooth beacons. Because battery consumption must be considered, designers often have to make trade-offs between power consumption and performance when choosing a chip. In other words, traditional Bluetooth beacons rely on battery power, and designers must balance power consumption and performance when selecting a chip. This limitation prevents designers from choosing chips solely based on performance or cost-effectiveness; they must also consider power consumption. This not only affects the overall performance of the Bluetooth beacon but may also lead to failure to meet actual needs in certain application scenarios, potentially sacrificing the overall performance or cost-effectiveness of the device. High-performance but high-power chips may accelerate battery consumption, thus increasing the frequency of replacement.

[0006] For solutions that aim to avoid battery replacement issues through direct power supply, existing technologies typically require a separate power interface and cabling for each Bluetooth beacon. This not only increases installation complexity but can also lead to messy wiring, affecting aesthetics and security. Modifying the wiring in an already renovated environment can be extremely difficult and may even require damaging the existing structure.

[0007] In addition to the issues mentioned above, traditional Bluetooth beacons generally rely on 3M adhesive or screws for installation, resulting in a limited range of methods. They typically use a single-wire connection, which is costly to pull. While dual-power interface options exist, they only support single-wire parallel connections, not tree-like parallel connections, limiting scalability. Traditional rainproof beacons incorporate sealing rings and are secured by rotating the outer shell or screws, but this increases installation and material costs. Furthermore, traditional wiring methods lack cable management and pull protection.

[0008] To address the aforementioned issues, the industry has been exploring new power supply methods to overcome the limitations of traditional battery power. Among these, direct power supply has attracted considerable attention due to its stable and reliable power supply and lower maintenance costs. However, how to effectively apply direct power supply to Bluetooth beacons, especially by reducing wiring complexity while ensuring device portability and flexibility, remains a current research hotspot and challenge.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by various orientation terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] An embodiment of this utility model provides a Bluetooth beacon device, such as... Figures 1 to 4 As shown, the Bluetooth beacon device 100 includes a beacon body 01, a Bluetooth circuit board 03, and a mounting base 02. The beacon body 01 has a receiving cavity, and the Bluetooth circuit board 03 is disposed within the receiving cavity. The Bluetooth circuit board 03 is used to transmit Bluetooth signals. The beacon body 01 is detachably mounted on the mounting base 02. The Bluetooth circuit board 03 is electrically connected to a power module 04, which provides operating voltage to the Bluetooth circuit board 03.

[0036] Understandably, the mounting base 02 can install the beacon body 01 on the ceiling or wall of a building. The Bluetooth circuit board 03 is located in the receiving cavity inside the beacon body 01, and the beacon body 01 is detachably mounted on the mounting base 02. When it is necessary to maintain the Bluetooth circuit board 03 or replace the beacon body 01, the beacon body 01 can be easily removed from the mounting base 02. After the maintenance of the Bluetooth circuit board 03 is completed or the replacement of the beacon body 01 is completed, the beacon body 01 can also be easily reinstalled on the mounting base 02.

[0037] Understandably, since the power module 04 is used to provide operating voltage for the Bluetooth circuit board 03, the Bluetooth beacon device 100 does not need to be equipped with a battery.

[0038] In some embodiments, such as Figures 1 to 3 As shown, the beacon body 01 also includes a bottom shell 11 and a faceplate 12. The faceplate 12 is detachably mounted on the bottom shell 11 to form a receiving cavity, and the Bluetooth circuit board 03 is detachably mounted on either the faceplate 12 or the bottom shell 11. The bottom shell 11 is detachably mounted on the mounting base 02.

[0039] Understandably, the faceplate 12 is detachably mounted on the bottom shell 11, and the Bluetooth circuit board 03 is detachably mounted on either the faceplate 12 or the bottom shell 11. This allows the Bluetooth circuit board 03 to be easily removed from its housing within the beacon body 01 for maintenance or updates.

[0040] In some embodiments, such as Figures 1 to 3 As shown, the bottom shell 11 is provided with a first protrusion structure 111, and the inner side of the first protrusion structure 111 is provided with a first sliding groove. The edge of the cover 12 is provided with a protrusion 121 that matches the first sliding groove. The protrusion 121 is slidably connected to the first sliding groove so that the cover 12 can be detachably installed on the bottom shell 11.

[0041] Understandably, by setting the first groove on the inner side of the first protrusion structure 111, the cover 12 and the bottom shell 11 can be slidably connected, effectively preventing rainwater from contacting the Bluetooth circuit board 03 and effectively protecting the Bluetooth circuit board 03.

[0042] For example, such as Figures 1 to 3 As shown, the bottom shell 11 is square, and the first protrusion structure 111 is provided on three sides of the bottom shell 11, so that the protrusion 121 can enter the first groove from the side of the bottom shell 11 where the first protrusion structure 111 is not provided, until the cover 12 can no longer move forward.

[0043] Understandably, when the bottom shell 11 is square, the first protrusion structure 111 can also be provided on two parallel sides of the bottom shell 11, so that the protrusion 121 can enter the first groove from the other two sides of the bottom shell 11 where the first protrusion structure 111 is not provided.

[0044] In some embodiments, such as Figures 1 to 3 As shown, the mounting base 02 is provided with a second protrusion structure 21, and the inner side of the second protrusion structure 21 is provided with a second sliding groove. The first protrusion structure 111 matches the second sliding groove, and the first protrusion structure 111 is slidably connected to the second sliding groove, and the bottom shell 11 is detachably mounted on the mounting base 02.

[0045] Understandably, such as Figures 1 to 3 As shown, similar to the arrangement of the first protrusion structure 111, the second protrusion structure 21 protrudes from the body of the mounting base 02. Similar to the connection method of the first sliding groove and the protrusion 121, the first protrusion structure 111 can slide into the second sliding groove to detachably mount the bottom shell 11 onto the mounting base 02.

[0046] In some embodiments, such as Figures 1 to 3 As shown, the mounting base 02 is provided with fixing holes 22 and wire grooves 23. The fixing holes 22 are used to fix the mounting base 02 with screws or cable ties. The wire grooves are used to fix the external wiring of the Bluetooth circuit board 03.

[0047] Understandably, both screw fixing and cable tie fixing are detachable fixing methods. By using screws or cable ties to install the fixing hole 22, the mounting base 02 can be installed on the wall, ceiling or other surface inside the building, or it can be removed from the wall, ceiling or other surface inside the building when needed.

[0048] For example, 3M adhesive can also be used to attach the mounting base 02 to a wall, ceiling, or other surface inside a building.

[0049] Understandably, the mounting base 02 has multiple cable trays 23 for wiring below the beacon body 01, which facilitates the fixing of the external wiring of the Bluetooth circuit board 03 and can greatly reduce the situation where the power cord is pulled off.

[0050] For example, such as Figure 1 and Figure 3 As shown, the cable tray 23 may include 3 cable trays with an angle of M (M ranges from 0 to 180).

[0051] In some embodiments, the Bluetooth circuit board 03 is detachably mounted on the faceplate 11 by screws.

[0052] In some embodiments, such as Figure 4 , Figure 5A and Figure 5B As shown, the Bluetooth circuit board 03 includes a main circuit 31, a power interface 32, and an indicator light circuit 33. The power interface 32 and the indicator light circuit 33 are electrically connected to the main circuit 31. The main circuit 31 is used to transmit Bluetooth signals. The indicator light circuit 33 includes indicator lights 331 (e.g., ...). Figure 5B LED1), indicator light 331 is used to indicate the operating status of the main circuit 31. The power interface 32 includes a first sub-interface 321, the first sub-interface 321 (e.g., ... Figure 5BU2) is used to connect to the power module 04 and to supply power to the main circuit 31 and the indicator circuit 33.

[0053] For example, such as Figure 5A and Figure 5B As shown, the Bluetooth circuit board 03 can broadcast Bluetooth positioning signals and has an LED indicator (LED1) to clearly show the working status of the Bluetooth beacon.

[0054] In some embodiments, such as Figure 4 , Figure 5A and Figure 5B As shown, the main circuit 31 includes a Bluetooth chip 310 and a reverse insertion voltage regulator circuit 311, which is connected between the first sub-interface 32 and the Bluetooth chip 310.

[0055] For example, as shown in Figure 5, the main circuit 31 includes a Bluetooth chip 310 (e.g., the Bluetooth chip can be a SYD8811 chip), a reverse insertion voltage regulator circuit 311 (e.g., the voltage regulator diode D1 can be a BZT52C4V7), a debugging circuit 312 (e.g., the pin header connector U5 can be an MTP310-1104S1), a DC-DC circuit 313, a 2.4G RF circuit 314, a crystal oscillator circuit 315, and a filter circuit 316. The reverse insertion voltage regulator circuit 311 at the front end of the main circuit 31 can prevent beacon malfunctions caused by incorrect connector insertion.

[0056] For example, the working principle and connection relationship of each circuit in the main circuit 31 can be referred to the relevant content of the SYD8811 chip.

[0057] In some embodiments, such as Figure 6 and Figure 7 As shown, the power module 04 includes a power supply 41 and a voltage conversion module 42. The voltage conversion module 42 is connected to the first sub-interface 331 and the power supply 41 respectively, and is used to convert the output voltage of the power supply 41 into the working voltage of the Bluetooth circuit board 03.

[0058] For example, the operating voltage of the Bluetooth circuit board 03 can be 3.5W.

[0059] In some embodiments, such as Figure 6 and Figure 7 As shown, power supply 41 includes a pico base station pRRU device.

[0060] Understandably, a pRRU device, also known as a pico base station, is a miniaturized, low-power, low-consumption micro-cellular base station primarily designed to solve indoor wireless coverage problems in specific areas, such as within a building (office building, shopping mall, train station, stock exchange, etc.). As the coverage of pRRU devices increases, drawing power from the pRRU device to power the Bluetooth beacon device 100 can significantly reduce the difficulty of wiring and is more convenient.

[0061] In some embodiments, such as Figure 6 As shown, the power interface 32 also includes at least one second sub-interface 322, any one of the at least one second sub-interface 322 being used to connect to the first sub-interface of other Bluetooth beacon devices and to power other Bluetooth beacon devices.

[0062] Understandably, such as Figure 8 As shown, the power interface 32 may also include at least one second sub-interface 322 to power other Bluetooth beacon devices (e.g., Bluetooth beacon device 200, Bluetooth beacon device 300, and Bluetooth beacon device 400), enabling tree-like parallel power supply.

[0063] For example, as shown in Figure 5 and Figure 8 As shown, the power interface 32 includes a first sub-interface 321 (e.g., Figure 5B U2) and two second sub-interfaces 322 (e.g., Figure 5B Taking U1 and U3 as examples, Bluetooth beacon device 100 can first draw power from pPRU device through first sub-interface 321, and then supply power to Bluetooth beacon device 200 and Bluetooth beacon device 300 respectively through two second sub-interfaces 322.

[0064] For example, the first sub-interface 321 and the second sub-interface 322 can be of the type of power PH2.0 interface, which can support parallel connection between multiple beacons.

[0065] In some embodiments, such as Figure 9 As shown, the power module 04 is another Bluetooth beacon device. The first sub-interface 321 is used to connect to the second sub-interface of other Bluetooth beacon devices and to draw power from other Bluetooth beacon devices.

[0066] Understandably, such as Figure 9 As shown, other Bluetooth beacon devices (such as Bluetooth beacon device 200) can also power Bluetooth beacon device 100 if they have at least one second sub-interface. In this case, the power module 04 of Bluetooth beacon device 100 can be considered as Bluetooth beacon device 200.

[0067] For example, such as Figure 8As shown, the power module 04 of the Bluetooth beacon device 400 can be considered as the Bluetooth beacon device 300.

[0068] The Bluetooth beacon device provided in this embodiment of the invention adopts a battery-free design. By eliminating the battery in the Bluetooth beacon and directly using a direct power supply, the battery cost and replacement issues are fundamentally solved. The Bluetooth beacon device provided in this embodiment of the invention features multiple power interfaces, allowing multiple Bluetooth beacons to be connected in a tree-like parallel configuration. This simplifies wiring complexity, avoids the wiring difficulties caused by multiple power supplies, and significantly reduces deployment and cabling costs. Since the Bluetooth beacon device provided in this embodiment of the invention is no longer limited by battery life, chip selection can focus more on economy and stability, rather than just power consumption, thus broadening the range of chip choices and increasing flexibility in chip selection. The Bluetooth beacon device provided in this embodiment of the invention offers diverse installation methods, with the mounting base supporting 3M adhesive, screw fixing, and cable tie fixing. The Bluetooth beacon device provided in the embodiments of this utility model adopts a rainproof design. The face cover of the beacon body slides from bottom to top and is fixed to the bottom shell of the beacon body, which can effectively prevent rainwater from contacting the Bluetooth circuit board and effectively protect the Bluetooth circuit board. In addition, a diode (anti-reverse insertion voltage regulator circuit) is designed at the front end of the main circuit, which can prevent the main circuit from malfunctioning due to incorrect insertion of the connector.

[0069] The following example illustrates the Bluetooth beacon device provided in an embodiment of this utility model.

[0070] like Figures 1 to 9 As shown, this Bluetooth active beacon consists of four parts: a mounting base (mounting base 02), a beacon bottom shell (bottom shell 11), a beacon faceplate (face shell 12), and a Bluetooth circuit board (Bluetooth circuit board 03). The mounting base is used to secure the beacon, supporting 3M adhesive, screws, and cable ties. The beacon bottom shell is used to slide and secure the beacon faceplate, effectively protecting it from rain. The Bluetooth circuit board broadcasts Bluetooth positioning signals, has three power interfaces supporting tree-like parallel connection, and includes LED indicators to clearly show the beacon's operating status. The Bluetooth circuit board is mounted on the beacon faceplate and secured by two positioning posts and two screws. The beacon faceplate is slidably closed and secured to the beacon bottom shell via a fixing strip on the bottom shell. The closed beacon faceplate and beacon base are also closed and fixed to the mounting base by sliding. The fixed position is above the mounting base. The Bluetooth circuit board has 3 power PH2.0 interfaces, which support parallel connection between multiple beacons. It supports parallel connection of tree structure through the 3.5V DC voltage output by PRRU.

[0071] In this example, the power supply is a digital indoor distribution PRRU device, which, after passing through a voltage conversion module, will output a 3.5V voltage suitable for the normal operation of the Bluetooth beacon.

[0072] Install the connected Bluetooth beacon on the indoor ceiling using cable ties (the installation method can be adjusted according to different ceiling materials and indoor structures, such as using adhesive or screws for installation), and conduct a pull test. The test results show that it meets the requirements for daily engineering applications.

[0073] Connect the PRRU device, transformer module, and Bluetooth beacon in sequence. Install the "nRFconnect" software on your phone, then bring the phone close to a properly powered Bluetooth beacon (number 47781). You should see that the phone can detect the signal from the Bluetooth beacon labeled "47781".

[0074] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
