Description

Technical Field

[0001] The present invention belongs to the technical field of mobile communication terminal positioning, and in particular relates to a non-smartphone and a mobile phone mainboard structure. Background Art

[0002] Traditional non-smartphones use Bluetooth for positioning. When the positioning and non-positioning parties are close, Bluetooth interaction is used for positioning. Bluetooth positioning requires the phone to have a Bluetooth module, be powered on, and have Bluetooth enabled. However, Bluetooth positioning has significant distance limitations and is not suitable for long-range positioning. To overcome this limitation, existing technologies use a GPS module combined with a GSM network for positioning.

[0003] GPS module + GSM network mode means using the phone's GPS module and GSM connection for positioning, with GPS positioning information transmitted back through the GSM Internet. During the positioning process, the phone needs to be turned on to power the GPS module and send positioning information through the GSM network. However, using this positioning method requires that the phone be equipped with a GPS module, turned on, and connected to the Internet.

[0004] However, when using the GPS module + GSM network mode for positioning, the mobile phone needs to be equipped with a GPS module. The GPS module has high power consumption, ranging from 20-200 milliwatts (mW), and at least 20-50mW is required. When using the GPS module to locate the mobile phone, the mobile phone needs to remain in power mode, and positioning cannot be achieved in power-off mode. In addition, the mobile phone needs to be connected to the Internet, otherwise the location information cannot be sent. At the same time, when searching, only Android or Apple devices can be selected, and searching devices with both systems are not compatible.

[0005] Therefore, providing a mobile phone mainboard structure to realize the location search of the mobile phone when it is not connected to the Internet has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0018] An antenna is used to transmit and receive UWB or Bluetooth signals.

[0019] In some embodiments, the UWB or Bluetooth chip supports working with the Apple Find My network and / or the Samsung SmartThings network.

[0020] In some embodiments, the LED light strip chip is used to:

[0021] Receive positioning instructions from the ultra-wideband module;

[0022] Control the LED light strip module to flash to indicate the location of the mobile phone.

[0023] In some embodiments, the power management chip module is used to:

[0025] When the phone is turned off, switch to an independent power source to power the UWB module.

[0026] The present invention also provides a non-smartphone, comprising the mobile phone mainboard structure described above.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention improves the mainboard structure and adds an independent power supply path for the battery-directly connected search module, allowing the search module to continue to operate normally when the phone is turned off and continuously broadcast location signals, avoiding the unified power supply limitations of traditional power management chips. The search module is directly powered to ensure that the device can still be located when it is turned off. At the same time, the present invention uses a UWB or Bluetooth module to replace the GPS module. By combining short-range high-precision positioning with Bluetooth low energy (BLE) technology, high-precision positioning in a low-power state is achieved. The UWB or Bluetooth module is integrated into the feature phone, combined with location broadcasting and signal reception in a distributed network, the positioning efficiency is improved, while energy consumption is reduced, making it suitable for the positioning needs of devices that are on standby for a long time.

[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] On the contrary, this application covers any alternatives, modifications, equivalents, and solutions made within the spirit and scope of this application as defined by the claims. Furthermore, to facilitate a better understanding of this application, certain specific details are described in detail below in the detailed description of this application. Those skilled in the art will be able to fully understand this application without these details.

[0034] See also Figure 1The mobile phone motherboard structure provided by the present invention is used for non-smartphones, which can be tablet phones or foldable screen phones, etc. The motherboard structure includes a main printed circuit board 1, a power supply module 2, a speaker module 3, a vibrator module 4, an LED line module 5, an earpiece module 6, an LED light strip chip, a power management chip module 8, an ultra-wideband module 9, a linear motor chip module 10, an LED light strip module 11 and a linear motor module 12; wherein, the LED light strip chip is respectively communicated with the LED line module 5, the power management chip module 8, the ultra-wideband module 9, the speaker module 3 and the LED light strip module 11, the ultra-wideband module 9 is respectively communicated with the LED line module 5 and the earpiece module 6, the power supply module 2 is respectively electrically connected with the power management chip module 8 and the ultra-wideband module 9, and the linear motor chip module 10 is respectively communicated with the linear motor module 12 and the vibrator module 4.

[0035] Specifically, the power supply module 2 includes a main battery and an independent power supply, and the independent power supply is communicatively connected to the ultra-wideband module 9 so as to power the ultra-wideband module 9 when the non-smartphone is in the off state; wherein the independent power supply is a rechargeable battery.

[0036] In this way, the present invention increases the independent power supply path of the battery-directly connected search module through the improved design of the mobile phone motherboard structure, so that the search module can still work normally when the mobile phone is turned off, and continuously broadcast the location signal, avoiding the unified power supply limitation of the traditional power management chip, directly powering the search module, and ensuring that the device can still be located when it is turned off. At the same time, the present invention uses UWB or Bluetooth module (ultra-wideband module 9) to replace the GPS module, and realizes high-precision positioning in a low-power state through the combination of short-range high-precision positioning and Bluetooth low energy (BLE) technology. The UWB or Bluetooth module is integrated into the feature phone, combined with the location broadcast and signal reception in the distributed network, which improves the positioning efficiency and reduces energy consumption, and is suitable for the positioning needs of devices that are on standby for a long time.

[0037] The search function of the prior art usually relies on a specific operating system (such as Android or iOS) and is not compatible with other systems. In order to solve the problem of being unable to achieve system compatibility, the ultra-wideband module 9 provided by the present invention includes a UWB or Bluetooth chip, a Bluetooth chip and an antenna, the UWB or Bluetooth chip is used to implement the ultra-wideband positioning function, the Bluetooth chip is used to communicate with external devices, and the antenna is used to transmit and receive UWB or Bluetooth signals. Using UWB or Bluetooth chips to replace GPS has lower power and can support collaborative work with Apple Find My network and / or Samsung Smart Things network to achieve cross-platform dual-system compatibility. By pre-integrating Apple's "Find My" network and Android's "Find My Device" network in the UWB or Bluetooth module, users can freely choose the system to search for devices. In this way, the present invention adopts a universal chip architecture and a cross-platform protocol design, and pre-writes the search program through an external module to achieve dual-system compatibility, and users do not need to replace devices due to system limitations.

[0038] To facilitate understanding, the following uses a specific usage scenario as an example to describe the working principles and steps of how a UWB or Bluetooth module uses three chips to implement positioning technology, and can work in conjunction with three software programs: Google FindMy, Apple Find My, and Samsung SmartThings.

[0039] 1. Use with Apple's "Find" function:

[0040] The internal structure of the UWB or Bluetooth module that works with Apple Find My is as follows Figure 2 As shown, the UWB or Bluetooth module provided by the present invention uses the TELINK TLSR8238 chip as the MCU. When the user initiates a search request, the TELINK TLSR8238 chip processes the Bluetooth BLE protocol and audio. The audio is processed by the MCU and output to the boost driver chip DC009S for amplification, driving the buzzer to make a sound. A 24MHz crystal oscillator is used in the UWB or Bluetooth module. When the mobile phone has sufficient power, the UWB or Bluetooth module synchronously transmits the signal to the speaker module 3, vibrator module 4, and LED circuit module 5 of the mobile phone, so that the speaker makes a sound, the mobile phone vibrates, and the LED on the body lights up, so that the user can quickly find the mobile phone. When the mobile phone battery is out of power, only the sound of the buzzer inside the UWB or Bluetooth module can be heard. However, when the user uses it for the first time, he needs to use the Find My APP to perform the binding operation. The specific steps for binding are as follows:

[0041] S11: Turn on the switch: Turn on the UWB or Bluetooth search switch, and then the phone enters the waiting state for pairing;

[0042] S12: Open the iPhone's native app: Find My;

[0043] S13: Select: Item;

[0044] S14: Select: Add item;

[0045] S15: Select: Other supported items;

[0046] S16: During the “searching item” process, the name of the device is searched;

[0047] S17: Click on the device found in the APP and name it;

[0048] S18: After naming, you can connect and use the device functions:

[0049] A. Call the device, click play sound, and the device will play music;

[0050] B. Network search helps find the device: When the device is out of Bluetooth range, it cannot be connected in the app. You can select Lost Mode, enable it, and enter a contact's phone number. If there is an iPhone near the lost device, the owner's Finder app can receive notifications and the latest location.

[0051] S19: Remove device: Remove the device in the APP, you can choose to remove the item.

[0052] 2. Use with Samsung's "Find" function:

[0053] The UWB or Bluetooth module provided by the present invention uses the Nordic52833 chip as the MCU to process the Bluetooth BLE protocol and audio. The audio is processed by the MCU and output to the boost driver chip DC009S for amplification, which drives the buzzer to produce sound. It uses 32MHz and 32.768KHz crystal oscillators. The internal structure of the UWB or Bluetooth module that works with Samsung Smart Things is as follows: Figure 3As shown, the product uses the Nordic52833 chip as the MCU. When the user initiates a search request, the Nordic52833 chip processes the Bluetooth BLE protocol and audio. The audio is processed by the MCU and output to the boost driver chip DC009S for amplification, driving the buzzer to make a sound. The UWB or Bluetooth module uses 32MHz and 32.768KHz crystal oscillators. When the phone has sufficient power, the UWB or Bluetooth module synchronously transmits the signal to the phone's speaker module 3, vibrator module 4, and LED circuit module 5, causing the speaker to make a sound, the phone to vibrate, and the body LED to light up, allowing the user to quickly find the phone. When the phone battery is dead, only the sound of the buzzer inside the UWB or Bluetooth module can be heard. However, the user needs to use the Samsung Smart Things APP to bind the operation for the first time. The specific steps for binding are as follows:

[0054] S21: Turn on the switch: Turn on the UWB or Bluetooth search switch on the phone;

[0055] S22: Binding: Device - Add device - Scan nearby devices - Check the use of location information and agree - follow the instructions on the picture displayed on the phone - wait for the device to connect;

[0056] S23: Call the product: You can call the product in "Ringtone and Volume" and change the ringtone yourself; or click "View Map" and click "Ring", you can also call the product and choose the volume.

[0057] S24: Remove device: Click the three dots in the upper right corner of the binding interface, you will see the words "Remove device", and follow the prompts.

[0058] 3. Use with Google FindMy:

[0059] Working with Google FindMy The internal structure of the Bluetooth / UWB module is as follows Figure 3As shown, the product uses the Nrf52832 chip as the MCU. When the user initiates a search request, the Nrf52832 chip processes the Bluetooth BLE protocol and audio. The audio is processed by the MCU and output to the boost driver chip DC009S for amplification, driving the buzzer to make a sound. The UWB / Bluetooth module uses 32MHz and 32.768KHz crystal oscillators. When the phone has sufficient power, the UWB module synchronously transmits signals to the phone's speaker module 3, vibrator module 4, and LED circuit module 5, causing the speaker to make a sound, the phone to vibrate, and the body LED to light up, allowing the user to quickly find the phone. When the phone battery is dead, only the sound of the buzzer inside the UWB / Bluetooth module can be heard. However, the user needs to use the Google Findmy APP to bind the operation for the first time. The specific steps for binding are as follows:

[0060] S31: Turn on the switch: Turn on the UWB / Bluetooth search switch on the mobile phone;

[0061] S32: Binding: Open Google FindMy device -> Connect -> Accept and continue -> Adding to Find My Device -> Add to Find My Device -> Open the Find My Device app to manage -> Done;

[0062] S33: Call the product: Click "Ring" to call the product, and you can choose the volume of the ringing sound;

[0063] S34: Click "Settings" to customize the device name and category;

[0064] S35: Remove: Remove from "Find My Device" -> Remove -> Confirm removal, the device will detect a prompt sound.

[0065] In the prior art, the positioning method only feeds back geographic location information, which makes it difficult to intuitively find the device in a complex environment. In order to solve this technical problem, the present invention redesigns the motherboard interface to connect the sound signal and light signal of the search module to the mobile phone motherboard, supports remote triggering of the device to make a sound or flash, and provides multi-sensory prompts even in the off state. Specifically, the LED light strip chip 7 is used to receive positioning instructions from the ultra-wideband module 9, and control the LED light strip module 11 to flash to indicate the location of the mobile phone. The sound signal output port and light signal output port of the tracking module are connected to the motherboard interface, and combined with an independent power supply path, to ensure that the search module can respond remotely in the off state, and realize the sound and flash prompt function in the off state.

[0066] In some embodiments, the power management chip module 8 is used to power each module when the phone is turned on; when the phone is turned off, it switches to an independent power supply to power the ultra-wideband module 9. Through the motherboard priority logic design, intelligent switching of power supply modes and dynamic power consumption management are achieved to improve module energy efficiency.

[0067] In order to solve the problem that the GPS module requires continuous power supply and cannot dynamically adjust power consumption, the present invention uses the unique calling method of the UWB or Bluetooth module to automatically switch to an independent power supply mode when it is turned off, and maintains the positioning signal broadcast through a low-power design, and only activates high-power functions (such as sound and flash) when a search command is received.

[0068] Furthermore, to address the issues of existing devices typically relying on mechanical buttons for activation, resulting in inconvenient operation and difficulty restoring the initial state, this invention replaces mechanical buttons with software control. Users can remotely control the module's on and off state, and the chip initialization program can be activated by repeatedly powering the phone's battery on and off, facilitating module recovery. The integrated software control logic and initialization program improve the module's usability and reliability through intelligent operation. The simplified motherboard design and integrated power, sound, and lighting interfaces reduce hardware complexity, making this technology suitable for a variety of low-cost devices and scenarios.

[0069] In addition to the above-mentioned mainboard structure, the present invention also provides a non-smartphone including the mainboard structure. The search process of the non-smartphone is as follows:

[0070] 1. Standby positioning stage

[0071] When the mobile phone is turned off, the power supply module 2 supplies power to the ultra-wideband module 9 through a redesigned independent power supply path;

[0072] The UWB module 9 starts to continuously broadcast location signals, which can be received by surrounding devices supporting corresponding protocols.

[0073] 2. Find response phase

[0074] When a user initiates a search command using other devices (such as an Apple device through "Find My" or an Android device through "Find My Device"), the UWB module 9 receives the command;

[0075] The ultra-wideband module 9 transmits the command signal to the LED light strip chip;

[0076] The LED light strip chip sends control instructions to the LED circuit module 5, the speaker module 3 and the linear motor chip module 10 according to the received signal;

[0077] The LED circuit module 5 drives the LED light strip module 11 to emit flashes; the speaker module 3 emits sounds; the linear motor chip module 10 controls the linear motor module 12 and the vibrator module 4 to generate vibrations, prompting the user the location of the phone from multiple sensory dimensions.

[0078] 3. Module recovery phase

[0079] Users can remotely turn on or off the search module through software control;

[0080] When the module needs to be restored to its initial state, the initialization program of the ultra-wideband module 9 and other chips is activated by repeatedly powering on and off the mobile phone battery.

[0081] The above specific implementation methods further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific implementation methods of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solutions of the present invention should be included in the scope of protection of the present invention.
