[0002] Car antennas are also called vehicle-mounted antennas. Generally, the antennas on cars are used for radios and radio stations on the car. They can be divided into built-in car antennas and external antennas. However, cars with different uses also have other antennas installed. For example, buses have DVB-T antennas and vehicle-mounted TV antennas. Logistics and taxis are also equipped with GSM antennas and GPS satellite antennas. Radio and radio station antennas are mainly AM / FM antennas, soft PCB digital antennas, AM / FM / TV antennas, etc. Depending on the different functions and uses, the frequencies of the antennas used are also different.

[0019] Specifically, the bottom of the buffer plate 5 is fixedly connected to the tops of the plurality of shock absorbing springs 7 and the plurality of rubber columns 8 .

[0020] In this embodiment, the shock-absorbing spring 7 and the rubber column 8 can play a buffering effect, and the rubber column 8 has a certain supporting effect; when the shock-absorbing spring 7 is subjected to external force, the shock-absorbing spring 7 and the rubber column 8 will absorb energy through deformation, thereby reducing the impact of the external force on the object; and the rubber column 8 can also provide additional support to prevent the object from sliding or deforming; in actual applications, the combination of the shock-absorbing spring 7 and the rubber column 8 is often used in shock absorption, vibration isolation and other occasions.
