Description

Technical Field

[0001] The present invention relates to the technical field of automobile anti-theft devices, and more particularly to the technical field of Bluetooth automobile anti-theft devices and anti-theft systems. Background Art

[0002] In modern life, with the development of cities and the increasing number of vehicles, finding remote controls after parking or when they've lost them is becoming increasingly challenging. At the end of a busy day, people often struggle to recall their vehicles in complex environments like shopping malls, airports, or multi-story parking lots due to fuzzy memories or familiar environments, making it difficult to accurately recall where they parked. Similarly, remote controls, as everyday items, can be easily misplaced or accidentally lost in places like homes and offices.

[0003] The traditional method is to use the remote control of the car alarm to make the vehicle sound the horn and flash the turn signal to indicate the vehicle's location and thus find the vehicle. However, the search range of this remote control is about 100 meters, which is relatively large. The smaller range in Europe is 30 meters.

[0004] The remote control, on the other hand, does not emit signals on its own and has no internal signal receiving circuit, meaning it cannot receive radio signals. Therefore, if the remote control is lost somewhere, it is difficult to find, and other important items such as keys and access cards that are hung on the same keychain with the remote control will also be difficult to retrieve. Utility Model Content

[0005] In response to the above problems, this application proposes a Bluetooth car anti-theft device and anti-theft system, aiming to provide a more intelligent, convenient and secure vehicle management and anti-theft solution, which can accurately locate the vehicle position and provide users with efficient search functions when the remote control is lost or the vehicle is difficult to find after being parked.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, the present application provides a Bluetooth car anti-theft device, comprising an anti-theft device provided with a power supply circuit, wherein the anti-theft device is built into a car;

[0008] A remote controller provided with a battery, the remote controller being capable of controlling the anti-theft device;

[0009] A Bluetooth module is built into the anti-theft device and / or remote control, and the Bluetooth module is powered by the power circuit or the battery respectively.

[0010] The application is connected with the anti-theft device through the Bluetooth module and is powered by the power supply circuit of the anti-theft device, and the Bluetooth module is connected with the remote controller and is powered by the battery of the remote controller, so that a stable power supply environment is provided, and the Bluetooth function can be used to sense the car and the remote controller within a short distance range, thereby facilitating the user to find.

[0011] In some possible embodiments, the anti-theft device and / or the remote controller are provided with a buzzer device that can sound a whistle.

[0012] In the second aspect, the application is a Bluetooth car anti-theft system, which comprises the Bluetooth car anti-theft device as described above, a control terminal connectable with the Bluetooth module;

[0013] The application further comprises an application program installed in the control terminal and connectable with the Bluetooth car anti-theft device and viewable of the signal strength of the Bluetooth car anti-theft device.

[0014] In some possible embodiments, the control terminal is provided with a global satellite navigation system.

[0015] The application program is provided with a disconnection record table that can acquire a current positioning location through the global satellite navigation system when the Bluetooth connection between the control terminal and the Bluetooth car anti-theft device is disconnected and save the disconnection record.

[0016] Thus, the application can narrow the range of searching for the Bluetooth car anti-theft device to tens of meters or even a few meters through the positioning location of the disconnected Bluetooth connection in the disconnection record table of the application program. That is, the range of searching for the car or the remote controller can be narrowed to a few meters.

[0017] In some possible embodiments, the application program further comprises a navigation button connectable with a third-party navigation software.

[0018] In some possible embodiments, the application program further comprises a call device button that can start the buzzer device of the Bluetooth car anti-theft device.

[0019] In a preferred embodiment, the control terminal is a smart phone.

[0020] In a preferred embodiment, the global satellite navigation system is GPS. BRIEF DESCRIPTION OF DRAWINGS

[0024] Figure 4 is a schematic diagram of the working process of a Bluetooth car alarm system. DETAILED DESCRIPTION

[0025] The following examples further illustrate the features of the present application and other related features, so as to facilitate the understanding of the skilled in the art:

[0026] First of all, the car alarm is an electronic device installed on the vehicle, used to prevent unauthorized personnel from starting or moving the vehicle. It is usually hidden inside the driver's cabin or engine compartment, which not only facilitates connection to the vehicle's electrical system, but also is not easily discovered or damaged by the outside. That is, the car alarm is built-in the car.

[0027] Correspondingly, the remote control is a portable electronic device that can control the alarm, allowing the user to control certain functions of the car from a distance. It communicates with the car through wireless signals, and the most common application is to unlock and lock the car doors. The vehicle can also be controlled by the remote control to make the horn sound and the turn signal flash, to indicate the location of the vehicle, making it easier to find the vehicle.

[0028] The problem to be solved by the present application is that, as mentioned above, the vehicle search range can reach about 100 meters, which is a relatively long range. Even under the European standard, it is only 30 meters. Moreover, the separate remote control only has a signal transmitting function and no receiving function, making it difficult to find.

[0029] As a short-range communication to shorten the sensing distance, the first choice is to use Bluetooth connection to control the car alarm and remote control to provide higher level of security protection. For example, use the latest Bluetooth encryption standard, such as AES (Advanced Encryption Standard) algorithm, to ensure the security and privacy of data transmission. At the same time, it can also be combined with smart phone applications to realize remote monitoring and operation, and users can view the vehicle status in real time and execute lock / unlock instructions through the phone.

[0030] In particular, please refer to Figure 1 , the alarm 1 is provided with a main chip, an input conversion circuit, an output drive circuit, a wire harness connection terminal, an RF receiving module, an RF receiving antenna, and therefore the alarm 1 will also be equipped with its own power supply circuit. For this, the Bluetooth module is built-in the alarm 1 by using the power supply circuit to power the Bluetooth module.

[0031] Please refer to Figure 2 , the remote control 2 is provided with a remote control encoding chip, an RF transmitting circuit, a PCB antenna, and a number of control buttons, and therefore the remote control 2 will be equipped with a battery. Also use this battery to build-in the Bluetooth module in the remote control 2, powered by the battery to power the Bluetooth module.

[0032] In specific applications, according to actual needs, the Bluetooth module can be configured in either the anti-theft device 1 or the remote control 2. Of course, the Bluetooth module can also be configured in both the anti-theft device 1 and the remote control 2. Preferably, the Bluetooth module can use a 2.4G Bluetooth chip.

[0033] This provides a stable power supply for the Bluetooth module while also enabling the Bluetooth function to sense the car and remote control at close range, making it easier for the user to find them. In some embodiments, the anti-theft device 1 and remote control 2 can also be equipped with a buzzer that can sound a horn. Buzzer devices are a common industry technology and will not be described in detail.

[0034] Please refer to Figure 3 The present application also provides a Bluetooth car anti-theft system using the Bluetooth car anti-theft device described above. In addition to the Bluetooth car anti-theft device, the Bluetooth car anti-theft system also includes a control terminal 3 connected to the Bluetooth module. Preferably, the control terminal 3 is a smartphone, but other smart terminals such as a pad can also be used.

[0035] The control terminal 3 is installed with an application. When used for the first time, the application can search for and connect to a Bluetooth car anti-theft device. After connection, the application can check the signal strength of the Bluetooth car anti-theft device. In other words, the distance can be determined based on the signal strength, making it easier to find the remote control in remote control applications. The application is an app (Application) that can be installed on a smartphone.

[0036] Furthermore, the control terminal is provided with a global satellite navigation system, preferably GPS (Global Positioning System). Of course, global navigation satellite systems such as BeiDou (BeiDou Navigation Satellite System), GLONASS (GLObal NAvigation Satellite System), and Galileo (Galileo) are also applicable.

[0037] The application program of this application includes a disconnection record table. When the Bluetooth connection between the control terminal 3 and the Bluetooth car anti-theft device is disconnected, the control terminal 3 can obtain a current location through the global satellite navigation system and save it in the disconnection record table. Specifically, when the typical Bluetooth distance is 10 meters, the longer Bluetooth distance can be 50 meters. For example, a Bluetooth distance of 50 meters is used. If the control terminal is 50 meters away from the car, the control terminal can obtain a current location through GPS, indicating that the location is 50 meters away from the car, and record this location in the disconnection record table.

[0038] By first reducing the distance to 50 meters by disconnecting the location recorded in the record, and then combining it with the Bluetooth car anti-theft device signal strength in the app, the search range for the Bluetooth car anti-theft device can be narrowed to more than ten meters, or even several meters. In other words, the search range for the vehicle or remote control 2 can be reduced to within a few meters. Of course, the remote control 2's own vehicle search function can also be used to find the vehicle at a short distance.

[0039] Furthermore, a navigation button can be linked to launch third-party navigation software in the app settings. Third-party navigation software can include popular navigation tools such as AutoNavi and Baidu Maps in China, Google Maps in the United States, and HERE WeGo in Germany. In other words, global satellite navigation systems and third-party navigation software can vary by region, and the scope of the anti-theft system in this case should not be limited by their application.

[0040] In some embodiments, especially in the application of the remote controller 2 , the application program may further set a call device button that can activate a buzzer of the Bluetooth car anti-theft device.

[0041] If the device is used indoors, the Bluetooth module can still maintain a connection with the phone within a certain range (about 50 meters). At this point, tapping the "Call Device" button on the app will cause the remote control 2 to emit a "Bi" sound or other melody, allowing the user to locate the remote control 2. Of course, you can further narrow the search range for the remote control 2 by combining the Bluetooth car alarm signal strength in the app before activating the "Call Device" button.

[0042] The following is a detailed description of this application through its application cases. Figure 4 When using it for the first time, open the mobile phone app, which is the application for the control terminal 3 described in this application, and search for a Bluetooth module within a 50-meter range to connect to the Bluetooth car anti-theft device. This can be the car's built-in anti-theft device 1 or the remote control 2. In this application case, the car anti-theft device 1 is used as an example.

[0043] When the mobile phone and the Bluetooth module of the anti-theft device 1 are kept within a range of 50 meters, the Bluetooth connection device for maintaining the connection with the anti-theft device is turned on. When the car is parked and the distance from the car is 50 meters, that is, when the distance between the anti-theft device 1 and the mobile phone exceeds 50 meters, the Bluetooth connection between the mobile phone and the anti-theft device is disconnected.

[0044] At this time, the APP on the mobile phone recognizes that the Bluetooth connection is disconnected, quickly obtains a current location through the mobile phone GPS positioning function, and saves it in the disconnection record table on the APP. The record in the disconnection record table at this time represents the GPS location of the anti-theft device 1.

[0045] When searching for the car, you can check the GPS location of the anti-theft device in the APP and click the navigation button to start the third-party navigation software to navigate to the disconnection location. This is the principle of the anti-theft system of this application that can more accurately locate the car's location.

[0046] When the mobile phone enters the 50-meter range of the car alarm, it will automatically connect to the Bluetooth car alarm. At this time, you can use the Bluetooth car alarm signal strength in the application or the car search function of the remote control 2 to find the car at a close distance.

[0047] If you are looking for remote control 2, you can click the call device button on the APP to start the siren to sound an alarm.

[0048] As mentioned above, this application protects a Bluetooth car anti-theft device and anti-theft system, and all technical solutions that are the same or similar to those in this case should be deemed to fall within the scope of protection of this case.
