Description

Technical Field

[0001] This invention relates to the field of vehicle anti-theft technology, and in particular to a license plate anti-tampering component and a vehicle. Background Technology

[0002] An on-board positioning terminal is an OBD terminal installed inside a vehicle. It can provide services such as vehicle location tracking, geofencing, overspeed alarms, trajectory playback, vehicle fault diagnosis, and OBD data detection. An on-board positioning terminal typically includes a positioning module and a communication module. The positioning module acquires the vehicle's location information, and the communication module transmits this information to a cloud server. Users then interact with the cloud server using their mobile devices (such as smartphones) to obtain the vehicle's location information, ensuring vehicle safety.

[0003] When vehicles are parked, some criminals may steal license plates, and vehicle-mounted positioning terminals cannot detect the removal and theft of license plates. Therefore, it is necessary to design a license plate removal prevention component with an alarm function. Summary of the Invention

[0004] The purpose of this invention is to provide a license plate anti-tampering component that can trigger an alarm when the license plate is removed and stolen, thereby achieving the license plate anti-theft function.

[0005] This invention provides a license plate anti-tampering component, including a vehicle-mounted positioning terminal and a beacon. The vehicle-mounted positioning terminal is installed on the vehicle body, and the beacon is installed on the license plate. The vehicle-mounted positioning terminal includes a positioning module, a short-range wireless communication module, a long-range wireless communication module, and a control module. The positioning module, the short-range wireless communication module, and the long-range wireless communication module are all electrically connected to the control module. The positioning module is used to acquire the location information of the vehicle-mounted positioning terminal, and the control module is used to transmit the location information acquired by the positioning module to a cloud platform through the long-range wireless communication module. The short-range wireless communication module is used to communicate with the beacon. When the beacon is outside the communication coverage range of the short-range wireless communication module, the control module sends a license plate loss alarm message to the cloud platform through the long-range wireless communication module.

[0006] In one possible implementation, when the beacon is outside the communication coverage of the short-range wireless communication module, the control module also sends a request message to the vehicle body. Upon receiving the request message, the vehicle body's anti-theft alarm activates to emit an audible and visual alarm.

[0007] In one possible implementation, the short-range wireless communication module is a Bluetooth module, and the beacon is a Bluetooth beacon.

[0008] In one possible implementation, the surface of the license plate closest to the vehicle body is the inner surface, and the beacon is used to mount on the inner surface of the license plate.

[0009] In one possible implementation, the inner surface of the license plate has a groove, and the beacon is used to be installed in the groove.

[0010] In one possible implementation, the license plate tamper-proof assembly further includes a sealant layer for adhering to the inner surface of the license plate at a position corresponding to the groove, so as to encapsulate the beacon within the groove.

[0011] In one possible implementation, the license plate includes a front license plate and a rear license plate, and the beacon includes a first beacon and a second beacon, the first beacon being mounted on the front license plate and the second beacon being mounted on the rear license plate.

[0012] In one possible implementation, the vehicle positioning terminal further includes a vehicle status detection module, which is electrically connected to the control module. The vehicle status detection module is used to detect the on / off state of the vehicle body. The control module is used to control the short-range wireless communication module to turn off when the vehicle status detection module detects that the vehicle body is in the on state, and to control the short-range wireless communication module to turn on when the vehicle status detection module detects that the vehicle body is in the off state.

[0013] In one possible implementation, the vehicle-mounted positioning terminal further includes a clock module, which is electrically connected to the control module and is used to provide time information; the control module controls the short-range wireless communication module to be turned off during a preset time period during the day and controls the short-range wireless communication module to be turned on during a preset time period at night.

[0014] The present invention also provides a vehicle including the license plate anti-tamper component described above.

[0015] The license plate anti-tampering component provided by this invention, by setting up an on-board positioning terminal and a beacon, since the on-board positioning terminal is installed on the vehicle body and the beacon is installed on the license plate, when the beacon is outside the communication coverage range of the short-range wireless communication module of the on-board positioning terminal, it indicates that the license plate has been removed from the vehicle body. At this time, the control module sends a license plate loss alarm information to the cloud platform through the remote wireless communication module, and then the cloud platform sends the license plate loss alarm information to the user's mobile terminal device, so that the user can know the license plate is lost in time through the mobile terminal device, increasing the probability of license plate retrieval and realizing the license plate anti-theft function.

[0024] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this invention are defined by the position of the structures in the drawings and the relative positions of the structures, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by this invention.

[0027] like Figures 1 to 8As shown, the license plate anti-tampering component provided in this embodiment of the invention is used for installation on a vehicle 4, which includes, but is not limited to, cars, trucks, and engineering vehicles. The vehicle 4 includes a vehicle body 41 (i.e., the vehicle itself) and a license plate 42 installed on the vehicle body 41. The license plate anti-tampering component includes an on-board positioning terminal 1 and a beacon 2. The on-board positioning terminal 1 is used for installation on the vehicle body 41, and is generally installed inside the vehicle body 41 (typically in the driver's cabin, etc.). The beacon 2 is used for installation on the license plate 42.

[0028] The vehicle-mounted positioning terminal 1 includes a positioning module 11, a short-range wireless communication module 12, a long-range wireless communication module 13, and a control module 14. The positioning module 11, short-range wireless communication module 12, and long-range wireless communication module 13 are all electrically connected to the control module 14. The short-range wireless communication module 12 performs short-range wireless communication, and the long-range wireless communication module 13 performs long-range wireless communication. The positioning module 11 receives positioning information, i.e., it acquires the location information of the vehicle-mounted positioning terminal 1. The control module 14 wirelessly transmits the location information acquired by the positioning module 11 to the cloud platform 5 (i.e., the cloud server) via the long-range wireless communication module 13. Users can interact with the cloud platform 5 through their mobile terminal devices 6 (such as mobile phones, computers, etc.) to obtain the location information of the vehicle-mounted positioning terminal 1, and thus the location information of the vehicle 4. (The specific functions and working principles of the long-range wireless communication module 13 and the positioning module 11 can be found in existing technologies and will not be elaborated here.)

[0029] The short-range wireless communication module 12 is used to communicate with the beacon 2 (specifically, to conduct short-range wireless communication). When the beacon 2 is outside the communication coverage of the short-range wireless communication module 12 (i.e., when the short-range wireless communication module 12 cannot communicate with the beacon 2), the control module 14 sends a license plate loss alarm message to the cloud platform 5 through the remote wireless communication module 13.

[0030] The license plate anti-tampering component provided in this embodiment of the invention, by setting up an on-board positioning terminal 1 and a beacon 2, since the on-board positioning terminal 1 is installed on the vehicle body 41 and the beacon 2 is installed on the license plate 42, when the beacon 2 is within the communication coverage range of the short-range wireless communication module 12, the short-range wireless communication module 12 can communicate with the beacon 2; since the communication coverage range of the short-range wireless communication module 12 of the on-board positioning terminal 1 is limited, when the beacon 2 is outside the communication coverage range of the short-range wireless communication module 12, that is, when the short-range wireless communication module 12 cannot communicate with the beacon 2, it indicates that the distance between the license plate 42 and the on-board positioning terminal 1 exceeds the preset range, thus determining that the license plate 42 has been removed from the vehicle body 41. At this time, the control module 14 sends a license plate loss alarm information to the cloud platform 5 through the remote wireless communication module 13, and then the cloud platform 5 sends the license plate loss alarm information to the user's mobile terminal device 6, so that the user can know that the license plate 42 is lost in time through the mobile terminal device 6, increasing the probability of the license plate 42 being found and realizing the license plate anti-theft function.

[0031] In one implementation, the short-range wireless communication module 12 is a Bluetooth module, and the beacon 2 is a Bluetooth beacon, enabling Bluetooth communication between the short-range wireless communication module 12 and the beacon 2. The communication coverage range of the short-range wireless communication module 12 can be within a range of 2 meters to 20 meters centered on the module, or within a range of 3 meters to 10 meters, etc. Of course, in other embodiments, the short-range wireless communication module 12 can also be other short-range communication modules.

[0032] like Figure 8 As shown, in one embodiment, license plate 42 includes a front license plate 42A and a rear license plate 42B. The front license plate 42A is installed on the front side of the vehicle body 41, and the rear license plate 42B is installed on the rear side of the vehicle body 41. Beacon 2 includes a first beacon and a second beacon. The first beacon is installed on the front license plate 42A, and the second beacon is installed on the rear license plate 42B. The short-range wireless communication module 12 is used to communicate with the first and second beacons. Thus, anti-theft protection for both the front license plate 42A and the rear license plate 42B can be achieved simultaneously.

[0033] like Figures 1 to 4 and Figure 8 As shown, in one embodiment, the surface of the license plate 42 closest to the vehicle body 41 is the inner surface 421, and the surface of the license plate 42 furthest from the vehicle body 41 is the outer surface 423. The beacon 2 is used to be fixedly installed on the inner surface 421 of the license plate 42. This arrangement improves the concealment of the beacon 2's installation position and, since the beacon 2 will be sandwiched between the license plate 42 and the vehicle body 41 after the license plate 42 is installed, it enhances the stability of the beacon 2's installation position, ensuring that the beacon 2 will not fall off during vehicle operation.

[0034] like Figures 1 to 4 and Figure 8 As shown, in one embodiment, a groove 422 is provided on the inner surface 421 of the license plate 42, and the beacon 2 is installed in the groove 422. This improves the concealment of the installation position of the beacon 2 and avoids the beacon 2 protruding from the inner surface 421 of the license plate 42 and affecting the installation of the license plate 42.

[0035] Specifically, the license plate 42 has a license plate number 420, which is formed by a portion of the license plate 42 protruding outward, thereby forming a groove 422 on the inner surface 421 of the license plate 42 corresponding to the position of the license plate number 420. (Specifically, the license plate 42 is generally made of metal. When manufacturing the license plate 42, after stamping a portion of the license plate 42, the portion of the license plate 42 protrudes outward and forms the license plate number 420, thereby forming a groove 422 on the inner surface 421 of the license plate 42 corresponding to the position of the license plate number 420; that is, the groove 422 is a structure inherent in the license plate 42 itself.) In this embodiment, the license plate number 420 includes a dot (not labeled in the figure). This dot mainly serves to separate characters, assist camera focusing, and prevent counterfeiting; the dot is a structure inherent in the license plate itself. Since the beacon 2 is generally a button-shaped or coin-shaped circular structure, the beacon 2 is installed in the groove 422 corresponding to the dot (the groove 422 corresponding to the dot is a circular groove, and the shape and size of the circular groove match the shape and size of the beacon 2), thereby improving the concealment and adaptability of the installation. Of course, in other embodiments, the beacon 2 can also be installed in the groove 422 corresponding to other license plate numbers 420, or installed in other locations (e.g., installed in a bolt used to install the license plate 42 onto the vehicle body 41).

[0036] like Figures 1 to 4 and Figure 8 As shown, in one embodiment, the license plate anti-tampering component also includes a sealant layer 3. The sealant layer 3 is used to adhere to the inner surface 421 of the license plate 42 at the position corresponding to the groove 422, so as to encapsulate the beacon 2 within the groove 422, thereby preventing the beacon 2 from falling off the license plate 42 and improving the concealment of the beacon 2 installation position (the sealant layer 3 is an opaque structure). During installation, the beacon 2 can be installed in the groove 422 first, then the sealant layer 3 can be adhered to the inner surface 421 of the license plate 42 at the position corresponding to the groove 422, and then the license plate 42 can be installed onto the vehicle body 41.

[0037] like Figures 5 to 8As shown, in one implementation, when the beacon 2 is outside the communication coverage of the short-range wireless communication module 12, the control module 14 also sends a request message to the vehicle body 41. After receiving the request message, the anti-theft alarm 412 of the vehicle body 41 will activate to emit an audible and visual alarm, thereby alerting the user so that the user can be aware of the loss of the license plate 42 in a timely manner and warning the criminals who steal the license plate 42.

[0038] Specifically, the vehicle positioning terminal 1 is generally plugged into the corresponding OBD interface inside the vehicle body 41 to enable charging of the vehicle positioning terminal 1 and data interaction between the vehicle body 41 and the vehicle positioning terminal 1 (i.e., the vehicle positioning terminal 1 and the vehicle body 41 are electrically connected via a wired connection). The vehicle body 41 is equipped with a vehicle controller 411 and an anti-theft alarm 412. The control module 14 of the vehicle positioning terminal 1 is electrically connected to the vehicle controller 411 of the vehicle body 41, and the vehicle controller 411 of the vehicle body 41 is electrically connected to the anti-theft alarm 412. When the beacon 2 is outside the communication coverage of the short-range wireless communication module 12, the control module 14 sends a request message to the vehicle controller 411. After receiving the request message, the vehicle controller 411 controls the anti-theft alarm 412 to activate and issue an audible and visual alarm.

[0039] like Figures 5 to 8 As shown, in one embodiment, the vehicle positioning terminal 1 further includes a vehicle status detection module 15, which is electrically connected to the control module 14. The vehicle status detection module 15 is used to detect the open / closed state of the vehicle body 41. The vehicle status detection module 15 may be a detection code integrated into the control module 14. The control module 14 is used to control the short-range wireless communication module 12 to turn off when the vehicle status detection module 15 detects that the vehicle body 41 is in the start state, and to control the short-range wireless communication module 12 to turn on when the vehicle status detection module 15 detects that the vehicle body 41 is in the off / closed state.

[0040] Specifically, since criminals will not remove or steal the license plate 42 when vehicle 4 is started, i.e., when vehicle 4 is in use, the control module 14 controls the short-range wireless communication module 12 to turn off after vehicle 4 is started, i.e., when vehicle 4 is detected by the vehicle status detection module 15 to be in the started state, in order to reduce power consumption and achieve the purpose of saving power. However, when vehicle 4 is parked, the probability of criminals removing or stealing the license plate 42 increases. Therefore, when vehicle 4 is parked and turned off, i.e., when vehicle status detection module 15 detects that vehicle 4 is in the off state, the control module 14 controls the short-range wireless communication module 12 to turn on, so as to activate the license plate anti-theft function. Of course, in other embodiments, the vehicle status detection module 15 may not be provided. In this case, regardless of whether the vehicle body 41 is in the starting state or the parked and turned off state, the control module 14 will control the short-range wireless communication module 12 to be turned on. The advantage of this setting is that when the vehicle 4 is driving under certain extreme road conditions, the license plate 42 may accidentally fall off under the action of violent vibration. At this time, since the license plate anti-theft function is kept on, an alarm will be issued in time after the license plate 42 is detected to have fallen off, thereby increasing the probability of the license plate 42 being recovered.

[0041] like Figures 5 to 8 As shown, in one embodiment, the vehicle-mounted positioning terminal 1 further includes a clock module 16, which is electrically connected to the control module 14. The clock module 16 is used to provide time information; specifically, the clock module 16 is used to provide the current Beijing time, and the clock module 16 can be a clock chip. The control module 14 controls the short-range wireless communication module 12 to be turned off during a preset time period during the day and controls the short-range wireless communication module 12 to be turned on during a preset time period at night.

[0042] Specifically, since criminals are more likely to remove and steal license plates 42 at night and less likely to do so during the day, the short-range wireless communication module 12 is configured to be turned on during a preset time period at night and off during a preset time period during the day to save power. The preset time period at night could be, for example, from 18:00 to 6:00 the next morning, with the remaining time period (6:00 to 18:00) being the preset time period during the day. Of course, in other embodiments, the clock module 16 may not be included; in this case, the control module 14 will control the short-range wireless communication module 12 to be on regardless of whether it is day or night.

[0043] In one implementation, the control module 14 controls the short-range wireless communication module 12 to operate intermittently (e.g., turning it on once every 1 to 30 minutes, for 0.5 to 5 minutes each time) to save power consumption. Of course, in other embodiments, the control module 14 can also control the short-range wireless communication module 12 to be continuously turned on.

[0044] In one implementation, the vehicle positioning terminal 1 also includes a housing and a circuit board (not shown). The circuit board is disposed within the housing, and the positioning module 11, short-range wireless communication module 12, long-range wireless communication module 13, control module 14, clock module 16, etc., are all disposed on the circuit board and electrically connected to the circuit board. Simultaneously, the vehicle positioning terminal 1 also includes a battery (not shown), which is electrically connected to the circuit board to power the vehicle positioning terminal 1. When the vehicle positioning terminal 1 is plugged into the corresponding OBD interface inside the vehicle body 41, the vehicle body 41 can charge the battery of the vehicle positioning terminal 1 and perform data interaction (the specific shape and structure of the vehicle positioning terminal 1 can be found in patents such as CN204196813U).

[0045] In one implementation, the remote wireless communication module 13 is a 2G / 4G dual-band network communication module, meaning it is compatible with both 2G and 4G networks. The positioning module 11 is a GPS / BD dual-positioning module, meaning it is compatible with both GPS and BeiDou positioning. The control module 14 can be an MCU, etc.

[0046] This embodiment also provides a vehicle 4, including a vehicle body 41, a license plate 42 installed on the vehicle body 41, and the aforementioned license plate anti-tampering component; wherein, the vehicle positioning terminal 1 in the license plate anti-tampering component is installed on the vehicle body 41, and the beacon 2 is installed on the license plate 42.

[0047] The license plate anti-tampering component provided in this embodiment of the invention, by setting up an on-board positioning terminal 1 and a beacon 2, since the on-board positioning terminal 1 is installed on the vehicle body 41 and the beacon 2 is installed on the license plate 42, when the beacon 2 is outside the communication coverage range of the short-range wireless communication module 12 of the on-board positioning terminal 1, it indicates that the license plate 42 has been removed from the vehicle body. At this time, the control module 14 sends a license plate loss alarm information to the cloud platform 5 through the remote wireless communication module 13, and then the cloud platform 5 sends the license plate loss alarm information to the user's mobile terminal device 6, so that the user can know the license plate 42 is lost in time through the mobile terminal device 6, thereby increasing the probability of the license plate 42 being recovered and realizing the license plate anti-theft function.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
