Detailed Description

In order to more clearly illustrate the embodiments of the utility model or the technical solutions of the prior art, the drawings which are used in the description of the embodiments or the prior art will be briefly described, it being obvious that the drawings in the description below are only some embodiments of the utility model, and that other drawings can be obtained according to these drawings without inventive faculty for a person skilled in the art.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

In the prior art, the V2X system comprises a V2X host and a V2X antenna, and for a small car, the V2X antenna can be arranged at the top of the car, for example, the V2X antenna is integrated with a shark fin antenna, so that communication is not influenced by structural members of the car, and a better signal receiving and transmitting effect can be achieved.

The conventional mode of arranging the radio frequency antenna on the roof can be shielded by factors such as carriages and cargoes, and the V2X communication distance requirement can not be met. Therefore, the V2X antenna provided in this solution is disposed at the widest portion of the outer contour of the vehicle, and two V2X antennas are simultaneously disposed, at which time the in-vehicle main unit is provided in the cab of the vehicle. Under the condition of being not blocked by the factors, the receiving and transmitting performance of the V2X signal is improved as much as possible. Here, the vehicle outer contour is the widest portion, which is the widest portion in the direction perpendicular to the vehicle traveling direction. The vehicle-mounted host is connected with the two V2X antennas in a wiring mode, and it is required to shorten the wiring as much as possible in order to ensure that the attenuation of signals on the wiring is low, so that the closer the installation position of the vehicle-mounted host is to the V2X antennas, the better.

In one embodiment, as shown in connection with fig. 1, the widest part of the vehicle outer contour of a typical truck is the distance d1 between two outside mirrors, which is larger than the width d2 of the cabin, while on a truck, in order to ensure a good view of the outside mirrors, the structure occupies a relatively large area, including the mirror body and the mounting bracket structure, and thus embodiments may be considered by disposing the V2X antennas p1 and p2 on the outside mirror structure, such as on the outside of the mirror body or in the cavity inside the mirror, or on the mounting bracket structure of the mirror.

In a specific implementation, the positions of the mounting brackets of the outside mirrors of different trucks are different, and two main forms are mainly shown in fig. 2, and one is that the mounting bracket is arranged on a door frame of a vehicle, so that the wiring arrangement of a V2X antenna and a vehicle-mounted host machine needs to be considered, and a door interlayer space of the truck generally has a relatively sufficient space for wiring (a radio frequency feeder line of the V2X antenna), so that the wiring can be arranged by means of the door interlayer space in the embodiment. In addition, because the vehicle-mounted host computer is in the cab, the safety and the aesthetic problems caused by the exposed wiring are considered, and the wiring connected with the V2X antenna is connected with the vehicle-mounted host computer in the cab through the soft hinge line pipe after passing through the interlayer space of the vehicle door.

In addition, the mounting point of the mounting bracket of the other type of outside rearview mirror is positioned on the front face of the vehicle, and in this case, the wiring between the V2X antenna and the vehicle-mounted host computer does not pass through the vehicle door, but can be deployed by directly penetrating out of the outside through the center console.

In a specific embodiment, the V2X system may further include one or more of a speaker, a 4G antenna, and a 5G antenna, and a GNSS antenna, and a WiFi antenna, which are connected to the vehicle-mounted host for completing communication, positioning, or prompting functions, and may further include an ETC module, which is also connected to the vehicle-mounted host for completing an ETC transaction.

In the foregoing embodiments, the descriptions of the embodiments are emphasized, and in part, not described or illustrated in any particular embodiment, reference is made to the related descriptions of other embodiments.

The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; while the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model, and are intended to be included in the scope of the present utility model.
