DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6A telescopic vehicle-mounted antenna assembly comprises a base 1, a first connecting member 2 is arranged on the base 1, a telescopic antenna assembly 3 is rotatably installed in the first connecting member 2, a second connecting member 4 is arranged on the base 1, an electric telescopic rod 5 is rotatably installed in the second connecting member 4, the electric telescopic rod 5 is arranged upwardly inclined and is located below the telescopic antenna assembly 3, a third connecting member 6 is rotatably installed at the telescopic end of the electric telescopic rod 5, and the third connecting member 6 is installed on the lower side wall of the telescopic end of the telescopic antenna assembly 3, a cover body 7 is arranged on the base 1, and the cover body 7 is wrapped around the outer side of the telescopic antenna assembly 3, a plurality of springs 8 are arranged on the base 1, and the plurality of springs 8 are all located inside the cover body 7, and the same cover body 9 is arranged on the top of the plurality of springs 8, and the cover body 9 is located above the telescopic antenna assembly 3 and above the cover body 7, and contacts with the cover body 7.

[0024] The power supply of the electric telescopic rod 5 can be controlled separately from inside the car. When the vehicle-mounted antenna needs to be used, the power supply of the electric telescopic rod 5 is driven to extend the telescopic end of the electric telescopic rod 5. Since its original state is in an upward tilted state, the telescopic end of the telescopic antenna assembly 3 is gradually tilted upward through the connection of the third connecting member 6. The first connecting member 2 provides a rotation support point for the telescopic antenna assembly 3. While tilting, the electric telescopic rod 5 is tilted synchronously. The second connecting member 4 provides a rotation support point for the electric telescopic rod 5. At the same time, the telescopic antenna assembly 3 gradually tilts upward and gradually extends. During the process of tilting and extending, the telescopic antenna assembly 3 presses on the bottom end of the cover body 9, causing the cover body 9 to gradually rise. At this time, the spring 8 is pulled, and a gap is generated between the cover body 9 and the cover body 7. The telescopic antenna assembly 3 extends from the gap to receive signals.

[0025] When the external environment is relatively bad or the car is turned off and parked, the driver drives the power of the electric telescopic rod 5 to retract the telescopic end of the electric telescopic rod 5. At this time, the telescopic antenna assembly 3 in the extended state gradually rotates and retracts, and is gradually stored in the cover 7. Since the cover 9 loses its thrust during the retraction process, the rebound force of the spring 8 after being pulled up gradually pulls the cover 9 back downward and fits with the cover 7, providing protection for the telescopic antenna assembly 3 and the electric telescopic rod 5 to prevent rain from entering and damage caused by strong winds.

[0026] Specifically, in the present embodiment, the telescopic antenna assembly 3 is composed of a plurality of telescopic joints 10, and the cross-section of one end of each telescopic joint 10 located inside the adjacent telescopic joint 10 is T-shaped, thereby improving the integrity of the telescopic antenna assembly 3 and preventing the telescopic joints 10 from detaching, thereby achieving the purpose of multi-section telescopic.

[0027] Specifically, in this embodiment, a sliding hole 11 is opened at each corner of the cover body 7, and a positioning column 12 is slidably installed in each sliding hole 11. Several positioning columns 12 are installed on the bottom end of the cover body 9 to provide a stable vertical movement guide for the cover body 9.

[0028] Specifically, in this embodiment, sealing grooves 13 are provided on both ends of the cover body 9 and the cover body 7 where they contact each other. The sealing grooves 13 are located on the outside of the positioning column 12. The same sealing ring 14 is adapted in the two sealing grooves 13 to prevent rainwater from seeping into the connection between the cover body 9 and the cover body 7.

[0029] Specifically, in the present embodiment, the top of the cover body 9 is in the shape of a shark fin and is hollow inside, which reduces the wind resistance during driving, reduces the weight of the cover body 9 , and reduces the power loss of the electric telescopic rod 5 .

[0030] Specifically, in this embodiment, the perimeter of the bottom of the cover body 9 is greater than the perimeter of the cover body 7 , so that rainwater is guided to the outside of the cover body 7 to prevent rainwater from flowing to the joint between the cover body 9 and the cover body 7 .

[0031] Specifically, in the present embodiment, the distance between the telescopic end of the telescopic antenna assembly 3 and the inner wall of the adjacent cover body 7 is much larger than the distance between the rotating end of the telescopic antenna assembly 3 and the inner wall of the adjacent cover body 7. The position of the telescopic antenna assembly 3 is offset toward the rotating end, so that the distance between the telescopic end and the inner wall of the adjacent cover body 7 is increased, thereby providing sufficient space for the telescopic joint 10 to be extended and retracted, thereby preventing the telescopic joint 10 and the third connecting member 6 from being affected by the inside of the cover body 7 during the tilting and retracting process, resulting in the problem of obstructed telescopic extension.

[0032] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
