Description

Technical Field

[0001] The present invention relates to the technical field of relay structures, and in particular to a relay component and a vehicle anti-theft safety system. Background Art

[0002] A positioning device uses satellite positioning and uploads the acquired positioning data to a server via a mobile communication module (GSM / GPRS network). A positioning device typically consists of a positioning module and a communication module. The positioning module is used to obtain the positioning device's location information, and the communication module then transmits this information to a cloud server. Users then interact with the cloud server using their mobile devices (such as mobile phones) to obtain the positioning device's location information.

[0003] Many vehicles are currently equipped with tracking devices to monitor their location and prevent theft. However, these devices are often not discreetly installed (typically in the driver's cab), making them easily discovered and easily removed. Once removed, these devices become difficult to locate, making it difficult to recover the vehicle. Summary of the Invention

[0004] The purpose of the present invention is to provide a relay assembly which integrates a positioning function and a switching function of the relay itself, thereby increasing the concealment of the positioning device and having a disassembly alarm function, thereby improving safety.

[0006] The disassembly detection module is arranged on the relay plug and / or the socket, the disassembly detection module is electrically connected to the circuit board, and the disassembly detection module is electrically connected to the control module; the disassembly detection module is used to trigger and send an electrical signal to the control module after the relay plug is separated from the socket, and the control module sends a disassembly alarm message to the cloud platform through the remote communication module after receiving the electrical signal.

[0007] In one feasible manner, a switch assembly is provided on the circuit board, the disassembly detection module is electrically connected to the circuit board through the switch assembly, and the switch assembly is electrically signal-connected to the control module; the control module is used to control the opening and closing of the switch assembly to connect or disconnect the disassembly detection module to the circuit board.

[0008] In one achievable embodiment, the disassembly detection module includes a light sensor and a light guide; the light sensor is disposed on the circuit board and electrically connected to the circuit board, and the light sensor is electrically connected to the control module; a housing wall is provided with a receiving hole, the receiving hole penetrating the housing wall, the receiving hole being disposed corresponding to the light sensor, and the light guide is disposed within the receiving hole;

[0009] When the relay plug is plugged into the socket, the side of the shell where the accommodating hole is provided abuts against the socket; when the relay plug is separated from the socket, the light sensor can convert the light signal into an electrical signal after receiving external light and send it to the control module.

[0010] In one possible implementation, the disassembly detection module includes a Hall sensor and a magnetic block; the Hall sensor is disposed on the circuit board and electrically connected to the circuit board, and the Hall sensor is electrically connected to the control module; the magnetic block is disposed on the socket;

[0011] When the relay plug is plugged into the socket, the Hall sensor and the magnetic block are close to each other and the distance between them is within a preset range; when the relay plug is separated from the socket, the Hall sensor and the magnetic block are away from each other and the distance between them exceeds the preset range, and the Hall sensor generates an electrical signal and sends it to the control module.

[0012] In one implementable manner, the circuit board includes a first sub-circuit board, a second sub-circuit board, a third sub-circuit board and a fourth sub-circuit board, the shell is provided with an L-shaped support plate, the support plate includes a first plate portion and a second plate portion that are integrally connected; the first sub-circuit board and the fourth sub-circuit board are arranged horizontally, and the second sub-circuit board, the third sub-circuit board and the support plate are arranged vertically; the fourth sub-circuit board is arranged with a vertical interval relative to the first sub-circuit board, and the fourth sub-circuit board is located above the first sub-circuit board; the second sub-circuit board, the third sub-circuit board and the support plate are all located between the fourth sub-circuit board and the first sub-circuit board, the second sub-circuit board is arranged with a gap relative to the first plate portion, and the third sub-circuit board is arranged with a gap relative to the second plate portion, the first sub-circuit board, the second sub-circuit board, the third sub-circuit board, the fourth sub-circuit board and the support plate are arranged to form a cubic structure and a receiving cavity is enclosed between the four sub-circuit board; the second sub-circuit board, the third sub-circuit board and the fourth circuit board are all electrically connected to the first circuit board;

[0013] The circuit module also includes a battery and a positioning antenna. The battery and the relay are both arranged on the upper surface of the first sub-circuit board and are electrically connected to the first sub-circuit board. The battery and the relay are both located in the accommodating cavity; the positioning antenna is arranged on the upper surface of the fourth sub-circuit board and is electrically connected to the fourth sub-circuit board. The positioning antenna is electrically connected to the positioning module.

[0014] In one feasible manner, a limiting portion is provided on the support plate, and the limiting portion is located in the accommodating cavity; a limiting groove is formed between the limiting portion and the relay, and the battery is arranged in the limiting groove.

[0015] In one feasible embodiment, the shell includes a main shell and a bottom cover connected to each other, the upper surface of the bottom cover is provided with a positioning groove, the first sub-circuit board is arranged in the positioning groove, the second sub-circuit board, the third sub-circuit board, the fourth sub-circuit board and the support plate are all arranged in the main shell; the second sub-circuit board, the third sub-circuit board and the support plate are all fixed to the first sub-circuit board, and the fourth sub-circuit board is fixed to the support plate.

[0016] In one implementable manner, the circuit module further includes an interference signal detection module, the interference signal detection module is disposed on the circuit board and electrically connected to the circuit board, the interference signal detection module is electrically connected to the control module, and the interference signal detection module is used to detect the intensity value of the interference signal around the relay assembly;

[0017] When the interference signal detection module detects that the intensity value of the interference signal reaches a first preset value, the control module sends a first-level shielding warning message to the cloud platform through the remote communication module;

[0018] When the interference signal detection module detects that the intensity value of the interference signal reaches a second preset value, the control module sends a second-level shielding warning message to the cloud platform through the remote communication module;

[0019] Among them, the second preset value is greater than the first preset value, and the first preset value and the second preset value are both less than a threshold; the threshold is the strength value of the interference signal when the remote communication module and the cloud platform cannot communicate remotely.

[0020] In one feasible embodiment, the circuit module further includes a short-range communication module, which is disposed on the circuit board and electrically connected to the circuit board, and the short-range communication module is electrically connected to the control module; the short-range communication module is used to wirelessly communicate with the short-range communication module in an external remote control device and / or other relay components.

[0021] The present invention also provides a vehicle anti-theft safety system, comprising a first relay device, a second relay device, an anti-theft alarm module, and a steering wheel lock module, wherein the first relay device and the second relay device are both relay assemblies as described above; the first relay device is electrically connected to the anti-theft alarm module, and the second relay device is electrically connected to the steering wheel lock module;

[0022] When the relay plug in the first relay device is separated from the socket, the control module in the first relay device sends a disassembly alarm message to the control module in the second relay device through the short-range communication module.

[0023] The relay assembly provided by the present invention incorporates a remote communication module, a positioning module, a control module, and a relay within a relay plug, thereby enabling the relay plug to simultaneously function as a positioning device and a relay on / off switch. This means that the relay assembly serves as both a relay and a positioning device. The integration of the positioning function into the relay assembly enhances the concealment of the positioning device, reducing the risk of discovery, disassembly, and damage by unauthorized personnel, thereby improving vehicle safety. Furthermore, because the relay and control module are electrically connected, users can use a mobile terminal to send control commands to the control module via the remote communication module, thereby controlling the opening and closing of the relay and achieving the corresponding function.

[0024] At the same time, by setting up a disassembly detection module, when the relay plug is disassembled from the socket, the disassembly detection module is triggered, and then the control module sends a disassembly alarm message to the cloud platform through the remote communication module. The cloud platform then sends the disassembly alarm message to the user's mobile terminal, so that the user can know in time that the relay assembly has been disassembled, realizing the disassembly alarm function of the relay assembly and improving the safety of the vehicle.

[0035] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0036] The terms "first," "second," "third," "fourth," and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a particular sequence or order.

[0037] The terms "up," "down," "left," "right," "front," "back," "top," and "bottom" (if any) used in the specification and claims of this invention are defined by the positions of structures in the accompanying drawings and the positions of structures relative to each other. These terms are intended solely for clarity and convenience in presenting the technical solution. It should be understood that the use of these terms does not limit the scope of protection claimed in this invention.

[0038] like Figures 1 to 7 As shown, an embodiment of the present invention provides a relay assembly, including a relay plug 100, a socket 300, and a disassembly detection module 4. The socket 300 is used to electrically connect to an electrical device (not shown), and the relay plug 100 and the socket 300 are plugged together to achieve electrical connection between the two. The relay plug 100 includes a housing 1 and a circuit module 2 disposed within the housing 1. The housing 1 is a sealed structure. The circuit module 2 includes a circuit board 21, a remote communication module 22, a positioning module 23, a control module 24, and a relay 25 (specifically, an electromagnetic relay). The remote communication module 22, positioning module 23, control module 24, and relay 25 are all disposed on the circuit board 21 and are electrically connected to the circuit board 21. The remote communication module 22, positioning module 23, and relay 25 are all electrically signal-connected to the control module 24 (specifically, the control terminals of the remote communication module 22, positioning module 23, and relay 25 are all electrically signal-connected to the control module 24 via the circuit board 21). Among them, the remote communication module 22 is used for remote wireless communication, the positioning module 23 is used to receive positioning information, and the control module 24 is used to wirelessly transmit the positioning information received by the positioning module 23 to the cloud platform 6 (i.e., the cloud server) through the remote communication module 22. The user's mobile terminal 7 (such as a mobile phone, computer, etc.) can interact with the cloud platform 6 for data, thereby obtaining positioning information (the specific functions and working principles of the remote communication module 22 and the positioning module 23 can be referred to the existing technology and will not be repeated here).

[0039] The disassembly detection module 4 is disposed on the relay plug 100 and / or the socket 300 . The disassembly detection module 4 is electrically connected to the circuit board 21 , and is also electrically connected to the control module 24 (specifically, the disassembly detection module 4 is electrically connected to the control module 24 via the circuit board 21 ). The disassembly detection module 4 is configured to trigger and send an electrical signal to the control module 24 when the relay plug 100 is separated (disassembled) from the socket 300 . Upon receiving the electrical signal, the control module 24 sends a disassembly alarm message to the cloud platform 6 via the remote communication module 22 . The cloud platform 6 then sends the disassembly alarm message to the user's mobile terminal 7 (for example, the control module 24 may send a message such as "Relay suspected of being disassembled" to the cloud platform 6 via the remote communication module 22 , and the cloud platform 6 then sends this message to the user's mobile terminal 7 to alert the user).

[0040] Specifically, relay 25 is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (stimulation quantity) meets a specified requirement. Relay 25 interacts between a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automated control circuits and is essentially an "automatic switch" that uses a small current to control a large current. In this embodiment, a plurality of thin metal pins 26 are provided on the circuit board 21. One end of each metal pin 26 is electrically connected to the circuit board 21 (specifically, the metal pins 26 and the circuit board 21 are welded), and the other end of each metal pin 26 extends outside the housing 1 (the housing 1 is provided with a through-hole 123 for the metal pins 26 to pass through). The socket 300 includes a base 31, a plurality of wires 32, and a plurality of docking terminals 33 spaced apart within the base 31. The docking terminals 33 are exposed from the base 31, and the plurality of wires 32 are connected to the plurality of docking terminals 33 in a one-to-one correspondence. The wire 32 is used to electrically connect to the electrical equipment; the multiple metal pins 26 are respectively plugged into and matched with the multiple docking terminals 33 in a one-to-one correspondence (in this embodiment, there are five metal pins 26 and five docking terminals 33). That is, when the relay plug 100 is plugged into the socket 300, the multiple metal pins 26 are respectively plugged into and electrically connected with the multiple docking terminals 33 in a one-to-one correspondence and contact with each other. At this time, the relay 25 in the relay plug 100 is electrically connected to the electrical equipment through the circuit board 21, the metal pins 26, the docking terminals 33 and the wire 32 in sequence, thereby enabling the relay 25 to control the opening and closing of the electrical equipment.

[0041] The relay assembly provided in the embodiment of the present invention incorporates a remote communication module 22, a positioning module 23, a control module 24, and a relay 25 within the relay plug 100, thereby enabling the relay plug 100 to simultaneously perform both positioning and relay switching functions. This means that the relay assembly serves as both a relay and a positioning device. Integrating the positioning function into the relay assembly increases the concealment of the positioning device, reducing the risk of discovery, disassembly, and damage by unauthorized individuals, thereby improving vehicle safety. Furthermore, since the control terminal of the relay 25 is electrically connected to the control module 24, meaning that the control module 24 can control the opening and closing of the relay 25, a user can use a mobile terminal 7 to issue control commands to the control module 24 via the remote communication module 22, thereby controlling the opening and closing of the relay 25 and implementing the corresponding function. (For example, when the relay assembly is used in a vehicle's door lock module, i.e., the relay assembly is electrically connected to the door lock and controls the opening and closing of the door lock, a user can use the mobile terminal 7 to issue door lock or door unlock commands to the control module 24 via the remote communication module 22, thereby locking or unlocking the vehicle door.)

[0042] At the same time, by setting up a disassembly detection module 4, when the relay plug 100 is disassembled from the socket 300, the disassembly detection module 4 is triggered, and then the control module 24 sends a disassembly alarm message to the cloud platform 6 through the remote communication module 22, and the cloud platform 6 then sends the disassembly alarm message to the user's mobile terminal 7, so that the user knows in time that the relay assembly has been disassembled, realizing the disassembly alarm function of the relay assembly and improving the safety of the vehicle.

[0043] In one embodiment, a switch assembly 27 is provided on the circuit board 21. The disassembly detection module 4 is electrically connected to the circuit board 21 via the switch assembly 27. The switch assembly 27 is also electrically connected to the control module 24 (specifically, the switch assembly 27 is electrically connected to the control module 24 via the circuit board 21). The control module 24 is configured to control the opening and closing of the switch assembly 27 to connect or disconnect the disassembly detection module 4 from the circuit board 21, thereby activating or deactivating the disassembly detection module 4. The rated operating current and rated operating voltage of the switch assembly 27 are lower than those of the relay 25. The switch assembly 27 may specifically be an electromagnetic switch, a MOSFET switch circuit, or the like. (Since the operating current and voltage of the disassembly detection module 4 are relatively low, only a smaller switch assembly 27 is required.)

[0044] Specifically, since the relay assembly requires live debugging during installation or replacement, the relay plug 100 and socket 300 may be disassembled. If the disassembly alarm function is normally enabled at this time, the disassembly detection module 4 may frequently trigger an alarm (false alarm), affecting the debugging operation. Therefore, this embodiment provides a switch assembly 27. When the control module 24 receives a forced alarm release signal from the mobile terminal 7, it controls the switch assembly 27 to close, disconnecting the disassembly detection module 4 from the circuit board 21 and thereby disabling the disassembly alarm function to avoid false alarms. When the control module 24 receives an alarm execution signal from the mobile terminal 7, it controls the switch assembly 27 to open, connecting the disassembly detection module 4 to the circuit board 21 and thereby restoring the normal disassembly alarm function (for example, the mobile terminal 7 is provided with options of "enabling the disassembly alarm function" and "disabling the disassembly alarm function." When the user selects the "disabling alarm function" option, a forced alarm release signal is generated; when the user selects the "enabling the disassembly alarm function" option, an alarm execution signal is generated).

[0045] like Figure 6As shown, as an embodiment, the disassembly detection module 4 includes a light sensor 41 and a transparent light guide 42. The light sensor 41 is disposed on the circuit board 21 and is electrically connected to the circuit board 21 (specifically, the light sensor 41 is electrically connected to the circuit board 21 via the switch assembly 27). The light sensor 41 is electrically connected to the control module 24. A receiving hole 121 is provided in the shell wall of the housing 1. The receiving hole 121 passes through the shell wall of the housing 1 and is provided corresponding to the light sensor 41. The light guide 42 is disposed within the receiving hole 121 and seals the receiving hole 121. The light guide 42 is specifically a light guide column. The light guide 42 not only guides light, but also seals the receiving hole 121 to prevent moisture, dust, etc. from entering the housing 1 through the receiving hole 121.

[0046] When the relay plug 100 is plugged into the socket 300, the side of the housing 1 provided with the accommodating hole 121 abuts against the socket 300 (specifically, the housing 1 abuts against the base 31). At this time, the external light cannot be irradiated onto the light guide 42 due to the obstruction of the socket 300, and cannot be transmitted to the optical sensor 41. At this time, the control module 24 does not perform the disassembly alarm action; when the relay plug 100 is separated from the socket 300, the light guide 42 is exposed, so that the light guide 42 can transmit the external light to the optical sensor 41. After receiving the external light, the optical sensor 41 can convert the optical signal into an electrical signal and send it to the control module 24, and the control module 24 then performs the disassembly alarm action.

[0047] like Figure 8 As shown, as another embodiment, the disassembly detection module 4 includes a Hall effect sensor 43 and a magnetic block 44. The magnetic block 44 can be a magnet, magnetic steel, or other magnetic material. The Hall effect sensor 43 is disposed on the circuit board 21 and electrically connected to the circuit board 21 (specifically, the Hall effect sensor 43 is electrically connected to the circuit board 21 via the switch assembly 27). The Hall effect sensor 43 is electrically connected to the control module 24. The magnetic block 44 is disposed on the socket 300 (specifically, the magnetic block 44 can be embedded in the base 31) and is positioned corresponding to the Hall effect sensor 43.

[0048] When the relay plug 100 is connected to the socket 300, the Hall sensor 43 and the magnet 44 are close to each other and the distance between them is within a preset range. At this time, the control module 24 does not execute the disassembly alarm action. When the relay plug 100 is separated from the socket 300, the Hall sensor 43 and the magnet 44 are separated from each other and the distance between them exceeds the preset range. The Hall sensor 43 generates an electrical signal and sends it to the control module 24, which then executes the disassembly alarm action. Specifically, the Hall sensor 43 is an electronic switch that uses a magnetic field as a sensor to control the device by detecting changes in magnetic field strength. It is a non-contact switch that can detect the presence of an object. The principle of the Hall sensor 43 is that it has a built-in magnet and a miniature electronic component. When it approaches an external magnetic field, it generates a voltage. In this embodiment, when the relay plug 100 is plugged into the socket 300, the distance between the magnetic block 44 and the Hall sensor 43 is relatively close, and at this time the Hall sensor 43 outputs a low level to the control module 24; when the relay plug 100 is disassembled from the socket 300, the magnetic block 44 and the Hall sensor 43 move away from each other, and the distance between the two exceeds the preset range. At this time, the Hall sensor 43 outputs a high level to the control module 24 (i.e., a level change occurs), thereby triggering a disassembly alarm.

[0049] In other embodiments, the disassembly detection module 4 may also include a light sensor 41 , a light guide 42 , a Hall sensor 43 and a magnetic block 44 , that is, either the light sensor 41 or the Hall sensor 43 will trigger an alarm to further ensure safety.

[0050] like Figures 2 to 4As shown, as an embodiment, the circuit board 21 includes a first sub-circuit board 211, a second sub-circuit board 212, a third sub-circuit board 213 and a fourth sub-circuit board 214. An L-shaped support plate 13 is provided in the housing 1. The support plate 13 includes a first plate portion 131 and a second plate portion 132 that are integrally connected. The first sub-circuit board 211 and the fourth sub-circuit board 214 are arranged horizontally, and the second sub-circuit board 212, the third sub-circuit board 213 and the support plate 13 are arranged vertically. The fourth sub-circuit board 214 is arranged relative to the first sub-circuit board 211 at an upper and lower interval, and the fourth sub-circuit board 214 is located above the first sub-circuit board 211. The second sub-circuit board 212, the third sub-circuit board 213 and the support plate 13 are all located between the fourth sub-circuit board 214 and the first sub-circuit board 211. The second sub-circuit board 212 is arranged opposite to the first plate portion 131, and the third sub-circuit board 213 is arranged opposite to the second plate portion 132. The first sub-circuit board 211, the second sub-circuit board 212, the third sub-circuit board 213, the fourth sub-circuit board 214 and the support plate 13 are arranged to form a cubic structure and the four sub-circuit board 210 is enclosed therebetween; the second sub-circuit board 212, the third sub-circuit board 213 and the fourth sub-circuit board 214 are all electrically connected to the first sub-circuit board 211.

[0051] The circuit module 2 also includes a battery 201 and a positioning antenna 202. The positioning antenna 202 is used to receive positioning signals, and the battery 201 is used to power the circuit module 2. The battery 201 and the relay 25 are both disposed on the upper surface of the first sub-circuit board 211 and are electrically connected to the first sub-circuit board 211. The battery 201 and the relay 25 are both located within the accommodating cavity 210. The positioning antenna 202 is disposed on the upper surface of the fourth sub-circuit board 214 and is electrically connected to the fourth sub-circuit board 214. The positioning antenna 202 is electrically connected to the positioning module 23. The remote communication module 22, the positioning module 23, and the control module 24 are disposed on the second sub-circuit board 212 and / or the third sub-circuit board 213.

[0052] Specifically, current circuit modules 2 typically utilize a single circuit board, meaning that only one circuit board is located within the housing 1 to support and mount various electronic components. Due to the large number of electronic components, the circuit board must be relatively large (typically rectangular in structure, with a relatively large length and width). This results in a relatively large overall size (length and width) for the relay plug 100, hindering the miniaturization of the relay assembly. This embodiment, by splitting the circuit board 21 into four smaller circuit boards and mounting the various electronic components on each of the four smaller circuit boards, can reduce the overall size of the relay plug 100, facilitating miniaturization of the relay assembly. Furthermore, since the positioning antenna 202 is located on the upper surface of the fourth sub-circuit board 214, signal obstruction to the positioning antenna 202 is reduced, enabling the positioning antenna 202 to better receive positioning signals.

[0053] like Figures 2 to 4 As shown, as an embodiment, a limiting portion 133 is provided on the support plate 13, and the limiting portion 133 is connected to the first plate portion 131 and the second plate portion 132 at the same time. The limiting portion 133 and the support plate 13 are an integral structure, and the limiting portion 133 is located in the accommodating cavity 210; the limiting portion 133 and the relay 25 form a limiting groove 130, and the battery 201 is arranged in the limiting groove 130, that is, the battery 201 is against the limiting portion 133 and the relay 25 at the same time, thereby limiting and fixing the battery 201.

[0054] like Figures 1 to 4 and Figure 6 As shown, as an embodiment, the housing 1 includes a main housing 11 and a bottom cover 12 connected to each other (in this embodiment, the main housing 11 and the bottom cover 12 are fixed by snapping). The top surface of the bottom cover 12 is provided with a positioning groove 122. The first sub-circuit board 211 is disposed in the positioning groove 122. The second sub-circuit board 212, the third sub-circuit board 213, the fourth sub-circuit board 214, and the support plate 13 are all disposed within the main housing 11. The second sub-circuit board 212, the third sub-circuit board 213, and the support plate 13 are all fixed to the first sub-circuit board 211, and the fourth sub-circuit board 214 is fixed to the support plate 13. The receiving hole 121 and the through hole 123 are both provided in the bottom cover 12. The metal pin 26 is provided on the bottom surface of the first sub-circuit board 211 and is electrically connected to the first sub-circuit board 211. The metal pin 26 passes through the bottom cover 12 and extends below the bottom cover 12.

[0055] Specifically, in this embodiment, the second sub-circuit board 212 and the third sub-circuit board 213 are both fixed and electrically connected to the first sub-circuit board 211 by welding (tin soldering) (specifically, the first sub-circuit board 211, the second sub-circuit board 212 and the third sub-circuit board 213 are all provided with soldering pads, and the soldering pads on the second sub-circuit board 212 are connected to the soldering pads on the first sub-circuit board 211 by welding, thereby achieving fixation and electrical connection between the two; the soldering pads on the third sub-circuit board 213 are connected to the soldering pads on the first sub-circuit board 211 by welding, thereby achieving fixation and electrical connection between the two); at the same time, the lower ends of the second sub-circuit board 212 and the third sub-circuit board 213 are both provided with protrusions 215, and the first sub-circuit board 211 is provided with a plurality of first locking holes 217, and the protrusions 215 on the second sub-circuit board 212 and the third sub-circuit board 213 are both inserted into and locked in the first locking holes 217 on the first sub-circuit board 211 to facilitate positioning and assembly and serve as auxiliary fixation. The support plate 13 is fixedly connected to the first sub-circuit board 211 via screws (not shown). The fourth sub-circuit board 214 rests on the second sub-circuit board 212, the third sub-circuit board 213, and the support plate 13. The support plate 13 is provided with a boss 134, and the fourth sub-circuit board 214 is provided with a second latching hole 216. The boss 134 is inserted into and latched into the second latching hole 216 to secure the fourth sub-circuit board 214 to the support plate 13. Furthermore, when the circuit module 2 is installed in the housing 1, the positioning antenna 202 abuts against the inner wall of the housing 1, further securing the fourth sub-circuit board 214. One of the fourth sub-circuit board 214 and the second sub-circuit board 212 is provided with a male connector 218, and the other is provided with a female connector 219 (in this embodiment, the fourth sub-circuit board 214 is provided with a male connector 218, and the second sub-circuit board 212 is provided with a female connector 219). The male connector 218 and the female connector 219 are plugged into each other to realize the electrical connection between the fourth sub-circuit board 214 and the second sub-circuit board 212, that is, the fourth sub-circuit board 214 is electrically connected to the first sub-circuit board 211 through the second sub-circuit board 212.

[0056] As an embodiment, the circuit module 2 also includes an interference signal detection module 28, which is arranged on the circuit board 21 and electrically connected to the circuit board 21. The interference signal detection module 28 is electrically connected to the control module 24 (specifically, the interference signal detection module 28 is electrically connected to the control module 24 through the circuit board 21). The interference signal detection module 28 is used to detect the intensity value of the interference signal around the relay assembly.

[0057] When the interference signal detection module 28 detects that the intensity of the interference signal reaches (i.e., is greater than or equal to) a first preset value, the control module 24 sends a first-level shielding warning message to the cloud platform 6 via the remote communication module 22, and the cloud platform 6 sends the first-level shielding warning message to the user's mobile terminal 7;

[0058] When the interference signal detection module 28 detects that the strength value of the interference signal reaches (i.e., is greater than or equal to) a second preset value, the control module 24 sends a second-level shielding warning message to the cloud platform 6 via the remote communication module 22, and the cloud platform 6 sends the second-level shielding warning message to the user's mobile terminal 7;

[0059] Among them, the second preset value is greater than the first preset value, and the first preset value and the second preset value are both less than the threshold value; the threshold value is the intensity value of the interference signal when the remote communication module 22 and the cloud platform 6 cannot communicate remotely (that is, when the interference signal detection module 28 detects that the intensity value of the interference signal reaches the threshold value, the remote communication module 22 and the cloud platform 6 will not be able to communicate remotely, and the remote communication module 22 cannot send shielding warning information to the cloud platform 6, that is, at this time the relay component has been shielded by the interference signal).

[0060] Specifically, in actual use, since the signals of the positioning module 23 and the remote communication module 22 are affected by external interference signals, some criminals use signal blockers to interfere with the normal operation of the positioning device, making it impossible for the user to track the vehicle's location information through the positioning device. Moreover, when the positioning device is interfered with by the signal blocker, it is unable to send an alarm message to the user in a timely manner, thereby achieving the purpose of stealing the vehicle. In this embodiment, an interference signal detection module 28 is set, and the control module 24 controls the interference signal detection module 28 to work continuously. The interference signal detection module 28 is used to detect the intensity value of the interference signal around the relay assembly. When the interference signal detection module 28 detects that the intensity value of the interference signal reaches a preset value, the control module 24 immediately sends a corresponding shielding warning message to the cloud platform 6 through the remote communication module 22. The cloud platform 6 then sends the shielding warning message to the user's mobile terminal 7, so that the user is promptly informed that the relay assembly is suffering from signal interference, realizing the signal interference warning function, avoiding vehicle loss, and ensuring property safety.

[0061] like Figure 9As shown, when the signal jammer is operating, the intensity of the interference signal it emits will first increase and then stabilize (the intensity of the interference signal is related to the operating power of the signal jammer. When the signal jammer is first turned on, its operating power will gradually increase, so the intensity of the interference signal it emits will gradually increase; after operating for a period of time (generally a few seconds to tens of seconds), its operating power will stabilize, and the intensity of the interference signal it emits will also stabilize). Therefore, the intensity of the interference signal detected by the interference signal detection module 28 will also first increase and then stabilize. When the interference signal detection module 28 detects that the intensity of the interference signal reaches the threshold, the remote communication module 22 and the cloud platform 6 will be unable to communicate remotely, and the remote communication module 22 will be unable to send the blocking warning information to the cloud platform 6. Therefore, it is necessary to set the first preset value and the second preset value to be less than the threshold so that the control module 24 can promptly send the blocking warning information to the cloud platform 6 through the remote communication module 22.

[0062] At the same time, by setting the first and second level warnings, it is possible to prevent false alarms. Specifically, since the relay component is exposed to a large number of interference signals during actual use, when the intensity of the interference signal reaches a first preset value, it is impossible to accurately determine whether it is an interference signal emitted by the signal blocker (it may be an interference signal unintentionally emitted by other devices). The control module 24 can send a message such as "suspected signal blocker interference detected" to the user's mobile terminal 7 through the remote communication module 22 and the cloud platform 6 to remind the user. When the intensity of the interference signal reaches a second preset value, since the intensity of the interference signal detected at this time is relatively large and general devices cannot generate such a strong interference signal, it can be determined that the relay component is likely to be interfered with by the signal blocker. At this time, the control module 24 can send a message such as "signal blocker interference detected, please deal with it in time" to the user's mobile terminal 7 through the remote communication module 22 and the cloud platform 6 to remind the user. Such a setting can not only avoid the relay component from being unable to issue early warning information in time (if only a second-level early warning is set, due to the high intensity of the interference signal at this time, the remote communication module 22 may not be able to smoothly send the early warning information to the cloud platform 6 under strong signal interference, resulting in early warning failure), but also avoid false alarms.

[0063] As an implementation, the first preset value is 20% to 50% of the threshold, and the second preset value is 40% to 70% of the threshold. For example, the first preset value is 30% of the threshold, and the second preset value is 60% of the threshold.

[0064] As an implementation manner, the method for determining the threshold value includes:

[0065] (1) Place the signal shield around the relay assembly so that the distance between the signal shield and the relay assembly is within a preset range (for example, the distance between the signal shield and the relay assembly is 1 meter);

[0066] (2) The control module 24 continuously (i.e., uninterruptedly) sends calibration information to the cloud platform 6 via the remote communication module 22. The calibration information may be any information (e.g., a number of characters, etc.);

[0067] (3) Adjust the operating frequency of the signal shield to f1, then turn on the signal shield to make the signal shield emit an interference signal, and obtain the intensity value of the interference signal emitted by the signal shield detected in real time by the interference signal detection module 28 (specifically, the relay component can be connected to a computer or other equipment, and the computer can be used to read the intensity value of the interference signal detected in real time by the interference signal detection module 28 to obtain a value similar to Figure 9 The relationship between the strength value of the interference signal and time shown);

[0068] (4) Obtaining the time point at which the cloud platform 6 is unable to receive the calibration information (i.e., at this time point, the cloud platform 6 loses the communication connection with the remote communication module 22);

[0069] (5) According to the time node, the strength value of the interference signal emitted by the signal blocker detected by the interference signal detection module 28 corresponding to the time node (i.e., the limit strength value) is obtained, which is recorded as RSSI1; for example, if the cloud platform 6 cannot receive calibration information starting from the 5th second after the signal blocker is turned on, then the time node is the 5th second, and the strength value of the interference signal detected by the interference signal detection module 28 at the 5th second is the limit strength value;

[0070] (6) Turn off the signal blocker;

[0071] (7) Adjust the operating frequency of the signal blocker to f2, f3, ...f n , and then repeat the above steps (3) to (6) respectively, and then obtain the corresponding interference signal strength values ​​RSSI2, RSSI3, ... RSSI emitted by the signal shield detected by the interference signal detection module 28. n , n is a positive integer greater than or equal to 3, the threshold = min (RSSI1, RSSI2, RSSI3, ... RSSI n ).

[0072] Specifically, since the remote communication module 22 generally has multiple operating frequency bands (e.g., 2G band, 3G band, 4G band, etc.), the signal jammer is generally also configured with multiple operating frequency bands to shield and interfere with each frequency band of the remote communication module 22. However, the intensity of the interference signal emitted by the signal jammer varies across the operating frequency bands, and the anti-interference capability of the remote communication module 22 for each frequency band is also inconsistent (i.e., the threshold value varies across different operating frequency bands). Therefore, to ensure that the remote communication module 22 can communicate with the cloud platform 6 in a timely and smooth manner when the signal jammer uses various operating frequency bands for interference, the maximum intensity values ​​of the interference signal corresponding to the remote communication module 22 being unable to communicate with the cloud platform 6 when the signal jammer uses various operating frequency bands for interference are tested. The minimum value among these maximum intensity values ​​is then taken to obtain the threshold value.

[0073] For example, the operating frequencies of the signal blocker are adjusted to 869-894 MHz, 925-960 MHz, 1805-1880 MHz, 1900-1990 MHz, and 2100-2200 MHz (the above frequency bands can basically cover all the operating frequency bands of the remote communication module 22 ), and the corresponding limit strength values ​​RSSI1, RSSI2, RSSI3, RSSI4, and RSSI5 are obtained respectively. Then, the minimum value of the five data is taken as the threshold.

[0074] It should be noted that the order of the above steps (2) and (3) cannot be reversed. If the signal blocker is turned on and regulated first and then the remote communication module 22 is controlled to send the calibration information to the cloud platform 6, due to the delay between the two operation steps, the signal blocker may have stabilized (or reached the threshold) before the remote communication module 22 sends the calibration information, thus causing measurement failure.

[0075] As one embodiment, the circuit module 2 further includes a short-range communication module 29. The short-range communication module 29 is disposed on and electrically connected to the circuit board 21. The short-range communication module 29 is electrically connected to the control module 24 (specifically, the short-range communication module 29 is electrically connected to the control module 24 via the circuit board 21). The short-range communication module 29 is used for wireless communication with the external remote control device 5 and / or short-range communication modules 29 in other relay assemblies. It should be noted that the short-range communication module 29 is used for short-range wireless communication (communication distance, for example, within 10 meters), while the long-range communication module 22 is used for long-range wireless communication. The communication distances and communication targets of the short-range communication module 29 are different. Specifically, the short-range communication module 29 may be a Bluetooth module (i.e., capable of Bluetooth communication), an infrared transceiver module (i.e., capable of infrared communication), a radio frequency transceiver module (i.e., capable of radio frequency communication), etc.

[0076] The purposes of providing the short-range communication module 29 are as follows: 1. The short-range communication module 29 can communicate wirelessly with the external remote control device 5, so that the user can quickly control the opening and closing of the relay 25 in the relay assembly through the external remote control device 5 (for example, when the relay assembly is used in the door lock module of a vehicle, the user can use the external remote control device 5 to quickly send a door lock command or a door open command to the control module 24 through the short-range communication module 29, so that the relay 25 opens or closes, thereby achieving the locking and unlocking of the vehicle door; compared with the method of using the mobile terminal 7 to send commands to control the opening and closing of the relay 25, this method of using the external remote control device 5 to send commands is simpler and faster). The external remote control device 5 can be a car remote control key. 2. The short-range communication module 29 can send alarm information (such as disassembly alarm information or shielding warning information) to other relay assemblies, so that other relay assemblies can perform opening and closing actions (i.e., realize the automatic interlocking function).

[0077] As an embodiment, the positioning module 23 is a GPS positioning module, and the positioning antenna 202 is a GPS ceramic antenna, which can receive GPS positioning information. The remote communication module 22 is a 2G / 4G dual-band network communication module, that is, the remote communication module 22 is compatible with communications on both 2G and 4G networks. The circuit module 2 also includes a communication antenna (not shown) and an interference signal detection antenna (not shown). The communication antenna and the interference signal detection antenna are both arranged on the circuit board 21 and are both electrically connected to the circuit board 21. The communication antenna is electrically connected to the remote communication module 22 through the circuit board 21, and the communication antenna is used to send and receive communication information; the interference signal detection antenna is electrically connected to the interference signal detection module 28 through the circuit board 21, and the interference signal detection antenna is used to receive interference signals around the relay assembly and transmit the interference signals to the interference signal detection module 28. The circuit board 21 is also provided with a SIM card slot (not numbered in the figure) for inserting a SIM card. The control module 24 is an MCU (microcontroller unit).

[0078] As an embodiment, a mounting plate 14 is further provided on the housing 1 , and a mounting hole 141 is provided on the mounting plate 14 , through which the relay plug 100 can be mounted and fixed at a desired position.

[0079] like Figure 10As shown, an embodiment of the present invention further provides a vehicle anti-theft safety system, comprising a first relay device A, a second relay device B, an anti-theft alarm module C, and a steering wheel lock module D. The first relay device A and the second relay device B are both relay assemblies as described above (i.e., the aforementioned relay assemblies are applied to the vehicle anti-theft safety system). The first relay device A is electrically connected to the anti-theft alarm module C, and the second relay device B is electrically connected to the steering wheel lock module D. Specifically, the relay plug 100 in the first relay device A is plugged into and electrically connected to the socket 300, which is electrically connected to the anti-theft alarm in the anti-theft alarm module C. The relay 25 in the first relay device A can control the on / off of the anti-theft alarm. The relay plug 100 in the second relay device B is plugged into and electrically connected to the socket 300, which is electrically connected to the steering wheel lock in the steering wheel lock module D. The relay 25 in the second relay device B can control the on / off of the steering wheel lock. The specific structure and operating principle of the anti-theft alarm module C and the steering wheel lock module D can be referred to in the prior art and will not be elaborated here.

[0080] When the relay plug 100 in the first relay device A is separated from the socket 300, the disassembly detection module 4 in the first relay device A is triggered. At this time, in addition to sending a disassembly alarm message to the cloud platform 6 via the remote communication module 22, the control module 24 in the first relay device A also sends a disassembly alarm message to the control module 24 in the second relay device B via the short-range communication module 29 (specifically, the first relay device A and the second relay device B transmit the disassembly alarm message via their short-range communication modules 29). After receiving the disassembly alarm message, the control module 24 in the second relay device B controls the relay 25 in the second relay device B to close, thereby locking the steering wheel lock in the steering wheel lock module D, thereby realizing the automatic interlocking anti-theft function.

[0081] Specifically, when a criminal attempts to steal a vehicle, after gaining access, they may remove the relay connected to the anti-theft alarm module C, rendering the anti-theft alarm module C inoperable and rendering the alarm inoperable (after the anti-theft alarm module C fails, the vehicle cannot provide audible or visual warnings, etc.). This embodiment interlocks the first relay device A and the second relay device B. When the first relay device A is removed, the second relay device B automatically closes, causing the steering wheel lock in the steering wheel lock module D to automatically engage. This renders the vehicle temporarily unusable, thereby increasing the owner's chances of recovering the vehicle and reducing the risk of vehicle loss.

[0082] In other embodiments, the relay assembly can also be applied to other occasions.

[0083] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person 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 based on the scope of protection of the claims.
