[0037] Working principle:

[0038] The utility model discloses a rivet-type vehicle-mounted antenna with high reliability, stable connection strength, long service life, and easy operation. Using a strong SUS304 rivet, one end of the rivet penetrates the antenna chassis 1, and the other end is pressed out from the outer end of the vehicle antenna rod of the vehicle antenna body. Through machine riveting, the vehicle antenna body is pressed and fixed, and the components of the vehicle antenna body cannot fall out of the rivet 2. The connection side 12 of the antenna chassis 1 aligns with the vehicle antenna body and connects to the vehicle antenna rod of the vehicle antenna body through the rivet 2. The vehicle antenna body is assembled by aligning with the vehicle antenna female socket installed on the vehicle body through the assembly side 11 of the antenna chassis 1.

[0039] Rivet 2 is a metal cylinder with a diameter slightly smaller than the rivet hole 131 in the vehicle antenna chassis 1. This cylinder is inserted through the vehicle antenna body. Pressure is applied at both ends of the rivet, causing the metal cylinder to deform and thicken, forming rivet heads at each end. The vehicle antenna body cannot be dislodged from rivet 2, and the antenna is secured using a punch rivet. The preload (clamping force) of rivet 2 is over 10% greater than that of high-strength bolts, effectively increasing the sliding load of the joint connection to the vehicle antenna chassis 1. This provides a more secure connection. Torque values ​​can reach over 8 Nm. Rivet 2 also exhibits excellent axial force consistency: Axial force stability tests have shown that the axial force fluctuation range of rivet 2 is controlled within 5%.

[0040] The utility model eliminates the traditional bolt and weld fastening method between the vehicle-mounted antenna chassis 1 and the vehicle-mounted antenna body, and instead adopts a quick rivet-type installation method. Rivets offer high reliability, strong connection strength, long life, and ease of use. The vehicle-mounted antenna is assembled using punch riveting, a process that rapidly applies force and achieves high riveting efficiency. The antenna chassis and rivet are interlocked at the riveted points, leaving the bottom free of burrs and burrs, thus avoiding stress concentration and withstanding high dynamic loads. The punch riveting process eliminates heat input, preventing damage to the antenna chassis' surface plating or passivation layer. Weld spatter and deformation are also avoided, resulting in an efficiency over three times that of welding.

[0041] Based on the ideal embodiment of the present invention, and through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.
