[0002] In order to realize intelligent transportation communication, the main means of realization is to combine vehicles with advanced wireless communication technology. Installing an on-board communication system on the vehicle can solve the communication problems encountered during driving, make driving safer and more convenient, and realize highly informationized and intelligent transportation. The on-board communication system relies on the reception and transmission of radio frequency signals to achieve communication.

[0003] At present, the antenna inside the vehicle-mounted RF signal receiving device usually has two forms: on-board printed antenna or welded antenna. The on-board printed antenna is made by printing a section of copper sheet on the substrate. The main metal material of the on-board printed antenna is copper, which has a low cost, but the signal receiving area is small, the sensitivity is low, and the signal receiving direction is limited by the shape of the antenna, and it cannot achieve omnidirectional signal reception; while the welded antenna, also known as the high-gain antenna, is mainly made by connecting the copper-nickel alloy to the substrate through the welding process. It has a wide receiving range and high sensitivity, but the cost of the alloy material is high and it is not suitable for use in low-cost occasions; in addition, the various parts of the common vehicle-mounted RF signal receiving device shell are mostly connected by screws or clamps. When the internal wearing parts such as the receiving module are damaged, it is difficult to carry out subsequent maintenance. For this reason, we propose a vehicle-mounted RF electronic signal receiving device to solve the above problems. Summary of the invention
