[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] As mentioned in the background section, the integrated OBU structure has revealed many inconveniences in actual use. For example, when the device experiences a transaction failure or needs to read or operate the data in the access card (also known as the IC card), such as when using a 13.56MHz or NFC reader at a service point, it is difficult for users to easily remove the access card from the OBU. Often, the entire OBU device needs to be painstakingly disassembled from its installation location, which greatly affects the user experience and the convenience of device maintenance.

[0044] In addition, while some detachable OBU structures exist in related technologies, such as those using mechanical connections like slide rails or clips, these connection methods suffer from structural complexity, inconvenient operation, and susceptibility to wear and loosening over long-term use. In the bumpy and vibrating environment of vehicle travel, loose connections may lead to poor electrical contact, resulting in communication interruptions or data reading failures, thus affecting the reliability of the ETC system.

[0045] Based on the aforementioned problems, this application provides a split-type vehicle-mounted device and ETC system. By separating the main structure and the split structure, a first connector is provided on the partition plate of the main structure, and a second connector is provided on the mounting shell of the split structure. The split structure is fixed to the main structure by magnetic adsorption of the first and second connectors. This embodiment uses magnetic force to achieve tool-free, one-click connection and separation between the split structure and the main structure. Compared with the sliding rail and buckle method used in traditional devices, this device is simpler and faster to operate, and there are no mechanical wear or jamming problems, resulting in a long service life.

[0046] See Figures 1 to 3 , Figure 1 This is a schematic diagram of the main structure and the split structure of the split vehicle-mounted device provided according to some embodiments of this application. Figure 2 This is a schematic diagram showing the separation of the main structure and the split structure of the split vehicle-mounted device according to some embodiments of this application. Figure 3 This is an exploded structural diagram of a split-type vehicle-mounted device according to some embodiments of this application. One embodiment of this application provides a split-type vehicle-mounted device that may include a main structure 100 and a split structure 200.

[0047] The main structure 100 includes a base 110, a partition plate 120, and a first connector 130. The base 110 has a receiving cavity 111 and an opening 112 communicating with the receiving cavity 111. The partition plate 120 is disposed near the opening 112 and connected to the base 110. The first connector 130 is disposed on the partition plate 120. The split structure 200 is detachably disposed on the main structure 100. The split structure 200 includes a mounting housing 210 and a second connector 230. The mounting housing 210 has a cavity for accommodating a access card. The second connector 230 is disposed on the mounting housing 210 and is configured to magnetically attract the first connector 130 so that one side of the mounting housing 210 abuts against the side of the partition plate 120 opposite to the receiving cavity 111.

[0048] It is understood that the main structure 100 in this embodiment is a fixed part, usually bonded to the windshield of the vehicle, while the split structure 200 is a movable part, usually used to carry the toll card.

[0049] Specifically, the base 110, serving as the base of the supporting device, is typically fixed to the vehicle's windshield or center console using strong adhesive. Its internal cavity 111 can accommodate the core electronic modules of the ETC system, such as the control motherboard, fixed-frequency communication module, and power management circuitry. The opening 112 on one side of the base 110 serves two purposes: firstly, to house the partition plate 120 to protect the internal core electronic modules; and secondly, to allow for docking with the split structure 200.

[0050] The partition plate 120 can be fixedly connected to the base 110 by means of clips, screws, adhesive, etc., and covers the opening 112. The partition plate 120 not only serves as a support surface when the split structure 200 is adsorbed, ensuring accurate installation position, but also isolates the communication components such as antennas installed in the base 110 from the second connector 230 (e.g., magnet) in the split structure 200, thereby reducing interference from strong magnetic fields on microwave antenna signals. In addition, to further ensure the installation accuracy of the split structure 200 and the main structure 100, the partition plate 120 can be set at a certain distance from the exit edge of the base 110, so that the side wall of the base 110 and the partition plate 120 form a limiting groove 160, allowing the split structure 200 to be fitted and embedded in the limiting groove 160.

[0051] In this embodiment, the first connector 130 can be disposed on the side of the partition plate 120 away from the receiving cavity 111, or it can be disposed on the side of the partition plate 120 facing the receiving cavity 111. For example, the first connector 130 is a magnet or a ferromagnetic material, and correspondingly, the second connector 230 is a magnet or a ferromagnetic material. For example, both the first connector 130 and the second connector 230 are magnets; or, in one example, one of the first connector 130 and the second connector 230 is a magnet, and the other is a ferromagnetic metal.

[0052] The split structure 200 in this embodiment can be designed as a card-like structure with a certain thickness for easy gripping and handling. The mounting housing 210 has an internal cavity for accommodating a standard ETC card (IC card). Exemplarily, the card is fixed inside the mounting housing 210.

[0053] The second connector 230 can be disposed within the cavity of the mounting housing 210 or on the outer wall of the mounting housing 210; there is no limitation on this. In this example, the second connector 230 can be an iron sheet or a permanent magnet with the opposite polarity to that of the first connector 130. The position of the second connector 230 corresponds precisely to the position of the first connector 130.

[0054] In this embodiment, the first connector 130 and the second connector 230 can be arranged in a multi-point symmetrical layout, such as distributed at the four corners of the corresponding structure, to ensure the balance and stability of adsorption and prevent shaking caused by single-point force.

[0055] During use, the user can bring the split structure 200 close to the partition plate 120 of the main structure 100. Under the magnetic attraction of the first connector 130 and the second connector 230, the two automatically generate a strong attraction force, guiding the mounting housing 210 to move accurately and quickly to the predetermined position, and making one side of it tightly abut against the side of the partition plate 120 away from the receiving cavity 111. When the user needs to use the access card separately, such as for recharging or querying at a service point, only a pulling force greater than the magnetic attraction force is needed to remove the split structure 200 from the main structure 100.

[0056] In this embodiment, the base 110, the partition plate 120, and the mounting housing 210 can all be made of engineering plastics, but there are no specific restrictions.

[0057] In summary, the split-type vehicle-mounted device provided in this application embodiment allows the main structure 100 and the split structure 200 to be separated. A first connector 130 is provided on the partition plate 120 of the main structure 100, and a second connector 230 is provided on the mounting housing 210 of the split structure 200. The split structure 200 is fixed to the main structure 100 by the magnetic adsorption of the first connector 130 and the second connector 230. This embodiment uses magnetic force to achieve tool-free, one-click connection and separation between the split structure 200 and the main structure 100. Compared with the traditional method of using slide rails and buckles, the operation of this device is simpler and faster, and there are no mechanical wear or jamming problems, resulting in a long service life.

[0058] Below, we will combine the appendix Figure 1 - Appendix Figure 6 The specific structure of the split-type vehicle-mounted device provided in the embodiments of this application will be described in detail.

[0059] like Figure 4 and Figure 6 As shown, Figure 4 This is a schematic diagram of the structure of the connecting plate of a split-type vehicle-mounted device provided according to some embodiments of this application. Figure 6This is a schematic diagram of the rear structure of the partition plate of a split-type vehicle-mounted device according to some embodiments of this application. In some embodiments, the partition plate 120 is provided with at least one first mounting groove 122, which is configured to receive a first connector 130; the side plate of the mounting housing 210 facing the main structure 100 is provided with at least one second mounting groove 2112, which is configured to receive a second connector 230; the second connector 230 and the first connector 130 are magnetically attracted to fix the split structure 200 to the main structure 100.

[0060] It is understandable that the first mounting groove 122 machined on the partition plate 120 can be a blind hole or a through hole, the shape of which is adapted to the shape of the first connector 130. The first connector 130 can be a permanent magnet or a metal sheet, usually designed as a cylindrical sheet. The first connector 130 can be fixed to the first mounting groove 122 by adhesive, or multiple elastic protrusions can be provided on the side wall of the first mounting groove 122. When the first connector 130 enters the first mounting groove 122, the elastic protrusions will deform to allow the first connector 130 to enter. When the first connector 130 is fully entered, the elastic protrusions will return to their original shape to lock the first connector 130 and prevent it from slipping out. Similarly, the way the second mounting groove 2112 is opened and the way it is connected to the second connector 230 can be made in the same way as described above, and will not be repeated here.

[0061] In this embodiment, the first mounting groove 122 and the second mounting groove 2112 can play a mechanical positioning role, thereby ensuring that the first connector 130 and the second connector 230 are accurately aligned when they are joined, avoiding the weakening of the adsorption force caused by misalignment, which is conducive to improving the reliability and repeatability of the combination of the split structure 200 and the main structure 100.

[0062] like Figure 5 and Figure 6 As shown, Figure 5 This is a front structural diagram of the partition plate of a split-type vehicle-mounted device provided according to some embodiments of this application. In some embodiments, the partition plate 120 has a plurality of first mounting grooves 122 on the side facing the receiving cavity 111; the mounting housing 210 includes a detachably connected connecting plate 211 and a cover 212, the connecting plate 211 and the cover 212 forming a cavity, and the connecting plate 211 has a plurality of second mounting grooves 2112 corresponding to the plurality of first mounting grooves 122 on the side facing the cavity.

[0063] For example, the multiple first mounting grooves 122 constructed on the side of the partition plate 120 facing the receiving cavity 111 are arranged in an array or symmetrically distributed to form multiple magnetic attraction points with the multiple second mounting grooves 2112, forming multi-point adsorption to enhance the adsorption force and stability of the split structure 200 and the main structure 100. Even in a bumpy vehicle environment, the split structure 200 is not easy to shake or fall off, which is beneficial to improving the vibration resistance performance.

[0064] In this embodiment, the connecting plate 211 and the cover 212 can be detachably connected by snaps or screws, so that the mounting housing 210 can be opened during manufacturing or maintenance to remove or insert the access card. The large surface of the connecting plate 211 can be designed as a flat surface for installing the access card, and the inner surface of the cover 212 can be designed as a concave surface to form a cavity with the connecting plate 211 for accommodating the access card.

[0065] In this embodiment, multiple second mounting grooves 2112 are machined on the side of the connecting plate 211 facing the cavity. This arrangement ensures that the outer surface of the connecting plate 211 is a smooth plane. Similarly, the design of the first mounting groove 122 on the partition plate 120 also ensures that the outer surface of the partition plate 120 is a smooth plane. This arrangement not only facilitates the seamless connection between the connecting plate 211 and the partition plate 120, but also prevents dust and other contaminants from entering the mounting groove.

[0066] like Figure 3 As shown, in some embodiments, the main structure 100 further includes a circuit board 140 and a light source 150, the light source 150 being electrically connected to the circuit board 140, and the circuit board 140 being disposed in the receiving cavity 111; the split-type vehicle-mounted device further includes a first light-transmitting element 300 and a second light-transmitting element 400, at least a portion of the second light-transmitting element 400 being disposed in the cavity, one end of the second light-transmitting element 400 passing through and exposed in the connecting plate 211, and the other end passing through and exposed in the cover 212; one end of the first light-transmitting element 300 passing through and exposed in the partition plate 120, and the other end being located in the receiving cavity 111; the first light-transmitting element 300 is configured to transmit the light emitted by the light source 150 to the second light-transmitting element 400 so as to transmit the light to the outside of the cover 212.

[0067] It is understood that the light source 150 electrically connected to the circuit board 140 can be an LED (Light Emitting Diode) lamp bead, and the circuit board 140 can control the switching, color, and flashing frequency of the light source 150. The first light-transmitting element 300 and the second light-transmitting element 400 can be optical fibers, transparent plastic light guides, or acrylic sheets. When the split structure 200 and the main structure 100 are connected, the first light-transmitting element 300 can capture and transmit the light emitted by the light source 150 to the second light-transmitting element 400, which then transmits the light to the outside of the cover 212 where it is visible. In this example, the first light-transmitting element 300 and the second light-transmitting element 400 can be fitted into the limiting holes of the partition plate 120, the connecting plate 211, and the cover 212 to prevent shaking. Furthermore, a through hole can be made on the access card to accommodate the passage of the second light-transmitting element 400, preventing interference between the access card and the second light-transmitting element 400.

[0068] In this embodiment, the light source 150 emits light of different colors or frequencies according to the ETC's operating status, such as Bluetooth connection, successful transaction, or low battery. The light passes through the first light-transmitting element 300, crosses the physical gap between the main structure 100 and the split structure 200, and couples to the second light-transmitting element 400, ultimately becoming visible outside the split structure 200. This method of transmitting light signals facilitates intuitive device status for the user, enhancing human-computer interaction.

[0069] like Figure 3 As shown, in some embodiments, the circuit board 140 is provided with a plurality of contacts 141; the partition plate 120 is provided with a plurality of through holes 121, each of which corresponds to a plurality of contacts 141. The contacts 141 pass through the through holes 121 and protrude outward from the partition plate 120; the connecting plate 211 is constructed with a plurality of through holes 2111 corresponding to the plurality of through holes 121. The plurality of through holes 2111 are configured to allow the contacts 141 to pass through for electrical connection with the chip pads of the access card.

[0070] Specifically, in this embodiment, the multiple contacts 141 on the circuit board 140 can be metal springs. In one example, the contact 141 includes a spring pin. To achieve electrical connection between the spring pin and the chip on the access card, multiple through holes 121 corresponding to the spring pin are machined on the partition plate 120. The spring pin passes through the through holes 121 and protrudes outward from the surface of the partition plate 120. Similarly, the connecting plate 211 is also machined with through holes 2111 corresponding to the through holes 121. When the split structure 200 is combined with the main structure 100, the contact 141 passes through the through holes 2111 on the connecting plate 211 and directly contacts the chip pads on the access card to achieve electrical connection.

[0071] In this embodiment, the through hole 121 and the through hole 2111 form an electrical path. The spring pin, in its convex state, ensures reliable contact with the access card pads. During assembly, the magnetic attraction compresses the spring pin, forming a stable electrical connection. In this example, the spring pin directly contacts the access card pads, reducing impedance and potential failure points from intermediate connectors, thus improving data transmission reliability. Furthermore, the through hole 121 and the through hole 2111 protect the spring pin from lateral forces during the assembly of the split structure 200 and the main structure 100, reducing deformation and wear.

[0072] like Figure 2 As shown, in some embodiments, the side wall of the base 110 near the opening 112 and the partition plate 120 form a limiting groove 160, and at least a portion of the split structure 200 is embedded in the limiting groove 160.

[0073] Specifically, the base 110 is usually designed as a long strip, and the design of the limiting groove 160 can constrain the split structure 200 to slide or rotate laterally, so as to achieve precise positioning of the split structure 200. At the same time, it also facilitates the precise docking of the contact 141 with the access card chip pad.

[0074] like Figure 1 and Figure 2 As shown, in one example, grips 240 are constructed on at least two opposing sidewalls of the cover 212, and the grips 240 are exposed outside the main structure 100.

[0075] Specifically, the grip portion 240 on the outer wall of the cover 212 makes it easy for users to grip with their fingers, solving the problem that the smooth surface of the cover 212 is difficult to grip, making the splitting action more effortless and intuitive.

[0076] In some embodiments, the grip portion 240 includes a groove formed on the sidewall of the cover 212; or, the grip portion 240 includes a protrusion disposed on the sidewall of the cover 212.

[0077] For example, the groove provided on the side wall of the cover 212 can be arc-shaped or finger-shaped, such as... Figure 2 As shown, this design facilitates fingertip insertion without increasing volume, thus improving the aesthetic appearance of the split structure 200. In this example, the groove can be integrally formed with the cover 212.

[0078] The protrusions on the side wall of the cover 212 can be rubber anti-slip strips or plastic bumps to provide friction and grip. The protrusions can be integrally formed with the cover 212 or attached by adhesive.

[0079] The grip portion 240 in this embodiment provides a clear point of force application, preventing the user from slipping or damaging the device due to excessive force.

[0080] Based on the same application concept, this application also provides an ETC system, which may include a back-end system, a lane controller, a roadside unit (RUS), a toll card; and the split-type on-board unit of the above embodiments.

[0081] It is understood that the back-end system in this embodiment may include a settlement center, a user management center, etc., to handle toll transactions and manage user accounts. The lane controller is located in the toll lane and can serve as the on-site control center. The roadside unit is connected to the lane controller and can communicate with the on-board unit via microwave through DSRC (Dedicated Short Range Communication) technology. The toll card is an IC card storing user identity and payment credentials information.

[0082] The normal passage and interaction process for vehicles can be as follows: When a vehicle enters the ETC lane, the split structure 200 and the main structure 100 are in a combined state, and the toll card is placed in the cavity of the split structure 200; the roadside unit continuously sends an inquiry signal; the DSRC communication module in the main structure 100 is activated and establishes a link with the RSU; the RSU requests vehicle identity information; the control board of the main structure 100 requests data from the toll card in the split structure 200 through the contact element 141 (such as a spring pin). After the toll card undergoes security authentication, it returns the encrypted account information to the main structure 100 through the contact element 141, and then the main structure 100 forwards it to the RSU. The RSU uploads the data to the lane controller and the back-end system to complete authentication and deduction. After successful deduction, an instruction is issued, the barrier is raised, and the vehicle passes through seamlessly.

[0083] When a user needs to go to a service point to recharge their access card, check detailed transaction records, or when the device occasionally fails to communicate and requires a separate card reader for diagnostics, the user does not need to disassemble the entire device. They can simply hold the grip 240 on the split structure 200 and apply a pulling force to remove it from the main structure 100; the magnetic connection is separated, and the electrical connection is disconnected.

[0084] Subsequently, the user takes the split structure 200 (containing the access card) to a 13.56MHz or NFC reader at a service point for direct operation. The card-like design of the split structure 200 makes it easy to hold and align with the reader. After the operation is complete, the user brings the split structure 200 close to the main structure 100, and the magnetic attraction automatically guides it to accurately reset and firmly connect, restoring the electrical connection, and the system can then be put back into normal use.

[0085] In this embodiment, when the access card needs to be operated or the device experiences a soft malfunction, there is no need to disassemble the main structure 100 installed on the vehicle, avoiding potential damage or insecure installation caused by repeatedly peeling and reapplying the adhesive backing. Furthermore, the multi-point magnetic attraction and limiting groove 160 design used in the split-type vehicle-mounted device, along with the highly reliable spring pin electrical connection, ensures the stability of the electrical connection even under long-term vehicle vibration.

[0086] In addition, the design of the split-type vehicle-mounted device in this embodiment is fully compatible with existing standard access cards, without changing the financial security authentication process. This ensures seamless integration with the back-end system and roadside units, while also reducing the cost and complexity of system upgrades.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
