Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted navigation and domain controllers, and in particular to a plastic panel integrated Bluetooth antenna protection cover structure. Background Art

[0002] In the rapidly developing field of smart car cockpits, electronic components are becoming more and more integrated and more powerful. Entry-level models are beginning to have Bluetooth and wireless network functions. With the popularization of mobile Internet, people's demand for in-car Bluetooth and wireless networks is also increasing. Whether in the process of driving or when parking for a rest, people need to be able to connect to the Internet anytime and anywhere to perform various operations. Therefore, the market prospects for in-car Bluetooth and wireless networks are very broad.

[0003] The technology of in-car Bluetooth and wireless network is also developing continuously. Now the in-car Bluetooth and wireless network are not just simple wireless network connection, but also include more functions, such as online navigation, voice control, video playback, etc. These functions have greatly improved the user experience.

[0004] Traditional Bluetooth and wireless network antennas use external antennas. This type of structure has a high cost and brings certain difficulties to production line production. In particular, the installation of antenna clips cannot be automated and needs to be installed manually by production line workers, which increases labor costs and does not meet the requirements of automated production. At the same time, there are potential risks such as improper installation of antenna clips.

[0005] To address this problem, we proposed a structure that uses ceramic antenna patches on printed circuit boards for Bluetooth and wireless network antennas, which greatly reduces material and labor costs. At the same time, in order to protect the ceramic antenna from external damage and ensure its signal stability, it needs to be protected with a plastic protective cover. The traditional structure is a single plastic protective cover to protect the ceramic antenna, which also increases material costs, mold costs and labor costs. In order to improve product competitiveness and facilitate automated production and assembly, we proposed a plastic panel integrated Bluetooth antenna protective cover structure design to solve the above problems.
