Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0027] According to an embodiment of the present application, a vehicle-mounted communication terminal is provided, which may be an OBU (OnBoard Unit) or an improved OBU. Figure 1 As shown, the vehicle-mounted communication terminal may include:

[0028] Terminal shell; a first main control board 4, a vehicle wireless communication V2X communication module is arranged on the first main control board 4, and the V2X communication module has a built-in V2X antenna 11; a second main control board 5, an electronic non-stop toll collection ETC communication module is arranged on the second main control board 5, and the ETC communication module has a built-in ETC antenna; the first main control board 4 and the second main control board 5 are connected by a connecting line.

[0029] Through the above-mentioned vehicle-mounted communication terminal, since the ETC communication module and the V2X communication module are integrated into one vehicle-mounted communication terminal, the problem of difficulty in installing the V2X vehicle-mounted unit when the vehicle is installed with the ETC vehicle-mounted unit can be avoided. At the same time, the V2X antenna 11 is built-in, which can solve the problem of difficulty in post-installation of the V2X vehicle-mounted unit, thereby facilitating the popularization of the V2X vehicle-mounted unit. At the same time, the ETC communication module and the V2X communication module are respectively set on different main control boards, which is conducive to the later maintenance of the equipment.

[0030] Optionally, the terminal shell includes an upper shell 2 and a lower shell 8, the lower shell 8 includes a first outer side surface and a second outer side surface, the first outer side surface is used for coordination installation with the vehicle, and the second outer side surface is located at the top of the vehicle communication terminal after the vehicle communication terminal is installed. The upper shell 2 is coordinated and installed with the lower shell 8, and the first main control board 4 and the second main control board 5 are arranged inside the cavity formed by the upper shell 2 and the lower shell 8.

[0031] The vehicle-mounted communication terminal needs to be installed in conjunction with the vehicle. Specifically, the second outer side surface can be glued to the front windshield of the vehicle to achieve the purpose of fixed installation. Of course, other installation methods can also be used, such as suction cup installation, which is not specifically limited here.

[0032] Optionally, the second main control board 5 is disposed on a first inner side surface of the lower shell 8 opposite to the first outer side surface, and the first main control board 4 is disposed in a direction of the second main control board 5 away from the first inner side surface.

[0033] An ETC communication module is provided on the second main control board 5, which is used to realize the interaction between ETC and the roadside unit and complete functions such as transaction charging. Therefore, it is necessary to ensure the signal strength of the ETC antenna signal received and sent, and directly connect the second main control board 5 to the lower shell 8 so that other components inside the vehicle-mounted communication terminal will not cause attenuation and interference to the ETC radio frequency signal, and ensure that the ETC antenna can maintain a facing direction with the roadside unit to ensure the success rate of the transaction.

[0034] Optionally, it also includes: a positioning antenna 7, which is installed below the second inner side surface of the lower shell 8 opposite to the second outer side surface and faces obliquely upward at a preset angle, wherein the positioning antenna 7 is a dual-frequency ceramic antenna.

[0035] Considering that the vehicle-mounted communication terminal is installed on the front windshield, and the glass has a certain inclination, such a design can ensure that after the device is installed, the positioning antenna 7 is still at the best angle for receiving signals.

[0036] Optionally, it also includes: an antenna partition 6, which is arranged in a direction where the positioning antenna 7 is away from the second inner side surface and forms an isolation cavity with the lower shell 8.

[0037] The positioning antenna 7 is isolated from other components of the vehicle-mounted communication terminal by the antenna partition 6, which can ensure that the positioning signal is not affected by other functions. Specifically, the antenna partition 6 can be made of metal or other materials that can isolate signals.

[0039] The V2X antenna 11 is located at the top of the device after the vehicle communication terminal is installed, which can ensure that the antenna will not be blocked and cause performance loss. In addition, the two antennas can be distributed on both sides of the positioning antenna 7 to ensure the isolation of the two V2X antennas 11 and avoid mutual influence due to being too close.

[0040] Optionally, it also includes: a mobile communication antenna 3, which is adhered to the third inner side surface of the upper shell 2 opposite to the first outer side surface, wherein the mobile communication antenna 3 is a flexible circuit board FPC antenna; the mobile communication antenna 3 can be a 4G antenna / 5G antenna, etc., which is not specifically limited here.

[0043] Optionally, a heat dissipation structure is also provided on the upper shell 2 for dissipating heat of the vehicle-mounted communication terminal. The mobile communication antenna 3 and the WIFI antenna 1 can be adhered to the inner side of the upper shell 2 by adhesive. When pasting, the heat dissipation structure needs to be avoided to prevent the signal from being blocked.

[0044] Optionally, it also includes: a power board 9, which is connected to the first main control board 4 through a connector. Specifically, the power board 9 is used to supply power to the vehicle-mounted communication terminal. Setting a separate circuit board can facilitate later maintenance. At the same time, in order to facilitate the arrangement of modules inside the device, the power board 9 can be set parallel to the second main control board 5.

[0045] Optionally, it also includes: a power harness 10, and the power board 9 can be connected to the charging interface or power interface of the vehicle through the power harness 10.

[0046] The vehicle-mounted communication terminal can realize ETC transactions and vehicle-road cooperative functions through the ETC communication module and the V2X communication module, without the need to install a separate V2X vehicle-mounted unit. At the same time, the ETC antenna and the V2X antenna 11 are built into the vehicle-mounted communication terminal to reduce the difficulty of installing the V2X external antenna due to the vehicle not supporting modification, thereby solving the problem in the related technology that the installation of the V2X vehicle-mounted unit is difficult and not easy to popularize. At the same time, other antennas set up inside can also complete the corresponding functions. Through the structural design and arrangement of the above-mentioned embodiments, the antenna modules do not interfere with each other, which can effectively ensure the performance of the antenna and the equipment.
