Since the antenna module 10 for vehicle of the present embodiment is designed through a structure, the second connector 230 of the antenna assembly 200 can be directly connected to the first connector 130 of the vehicle-mounted antenna system box 100 in a structural and electrical manner. Compared with the conventional method of electrically connecting the vehicle-mounted data communication system box and the antenna module by wire connection, the vehicle antenna module 10 of the present embodiment can directly convert the wireless communication analog signal received by the antenna assembly 200 into a digital signal through the vehicle-mounted data communication system box 100, so as to effectively reduce interference and high frequency communication line loss, reduce the usage amount of coaxial cable, and further reduce the production cost.

In addition, during detachment, please refer to fig. 2A, fig. 3A, fig. 5B, fig. 5C, fig. 5D and fig. 5E again, for example, an end of the antenna assembly 200 is clamped by the detaching tool 20, and a second force F2 (such as a pressure) is applied to the antenna assembly 200 to deform the first buckling parts 120a and 120B. Then, when the antenna assembly 200 is moved by a third force F3 in the second direction D2 opposite to the first direction D1 so that the

inclined surface portions

280a and 280b move, the

second locking portions

220a and 220b do not interfere with the

first locking portions

120a and 120b, the second sliding

portions

210a and 210b do not interfere with the first sliding

portions

110a and 110b, and the second connector 230 does not interfere with the first connector 130, so that the antenna assembly 200 is detached from the vehicle-mounted accessibility system box 100.

In brief, in the assembly method of the antenna module 10 for a vehicle of the present embodiment, when the second sliding

connection portions

210a and 210b of the antenna assembly 200 slide along the first sliding

connection portions

110a and 110b through the pushing force, the

second locking portions

220a and 220b are locked to the

first locking portions

120a and 120b, so that the second connector 230 is electrically connected to the second connector 130. Thus, the antenna assembly 200 can be assembled on the vehicle-mounted telematics system box 100 in a sliding manner, and the assembly process can be simplified. In addition, during detachment, the antenna assembly 200 can be detached from the vehicle-mounted communication system box 100 by directly applying a force to the antenna assembly 200 through the detaching tool 20 or a user, and deforming the

first locking portions

120a and 120b, so that the detachment process is simplified.
