Description

Vehicle-mounted 5G, NR antenna

Technical Field

The invention relates to the field of automobile antennas, in particular to a vehicle-mounted 5G, NR antenna.

Background

The automobile antenna is a device for intercepting high-frequency electric waves transmitted by a transmitting station and transmitting the high-frequency electric waves to a receiver of an automobile radio, an automobile telephone or radio navigation equipment so as to demodulate carrier waves; commonly used antennas are mainly whip antennas and shark fin antennas. The whip antenna and the shark fin antenna are arranged outside the automobile, the whip antenna is long and has strong signal collection capacity, and the whip antenna can also receive signals in a remote mountain area, so that the whip antenna is very suitable for an owner who often runs outdoors, but the whip antenna is easy to break in strong wind and strong rain during the driving process of the automobile and is easy to freeze in strong snow, so that the whip antenna and the shark fin antenna are damaged; the shark fin antenna has a streamline appearance design, and is installed behind a vehicle roof, so that the attractiveness and the movement of the whole vehicle are improved. The shark fin antenna has a streamlined appearance, and can play a role in reducing wind resistance by means of turbulence when an automobile runs. The shark fin antenna is low in height, the signal receiving capacity is correspondingly reduced, and the shark fin antenna is relatively laborious in remote mountain areas and other areas with weak signals. For this reason, a vehicle-mounted 5G, NR antenna is proposed to solve the above-mentioned problems of both antennas.

As shown in fig. 1, the housing 1 is streamlined in shape. As shown in fig. 3 and 4, when the first motor 2 is not activated, the antenna rod 502 is arranged between the two clamping rings 302. The clamping ring 302 is pressed against the transition turntable 3 through the spring 304, so that the antenna rod 502 is clamped; after the first motor 2 is started, the clamping ring 302 firstly takes the antenna rod 502 to extend out of the moving pipe 501, then clamps the moving pipe 501 along the conical end of the moving pipe 501, and then extends the moving pipe 501 and the antenna rod 502 out of the fixed pipe 5; the antenna rod 502 is prevented from being removed from the moving tube 501 by a mounting stopper. As shown in fig. 5, when the moving pipe 501 moves, the first gear 5004 connected to the moving pipe will rotate along the complete rack formed by the first rack 5003 and the second rack 601, and when the moving pipe 501 cannot move from the fixed pipe 5, the fourth motor 7 drives the second bevel gear 701, so as to drive the first bevel gear 602 and the rotating ring 6 to rotate 180 °, at this time, the first rack 5003 and the second rack 601 do not form a complete rack any more, so that the first gear 5004 is locked when the first gear 5004 abuts against two parallel racks, and the gear teeth are not damaged because the two racks are used to lock the gears; thereby preventing the fixed tube 5 from rotating, and the movable tube 501 retracts into the fixed tube 5 due to the weight of the antenna rod 502 and the movable tube 501;

as shown in fig. 6, when the first motor 2 is not started, the PU belt 802 connecting the first pulley 8 and the second pulley 801 is in a slack state, and the PU belt 802 is kept connected with the first pulley 8 and the second pulley 801 all the time by the limiting mechanism 9; after the first motor 2 is started, the third rotating shaft 1101 is driven to rotate through the synchronous wheel 1105 and the synchronous belt, so that the chain 1104 of the driving sprocket 1103 rotates, and when the chain 1103 rotates, the horizontal plate 1005 is driven to move upwards through the elastic plate mechanism 12, so that the sliding block 1001 is driven to move upwards; the slider 1001 moves upward simultaneously with the link frame 1002 to which it is fixedly attached, so that the roller 1003 sandwiching the PU tape 802 moves upward, thereby gradually tightening the PU tape 802, and the second annular groove 1004 of the roller 1003 is provided to prevent the PU tape 802 from falling off. After the PU belt 802 is tightened, the first belt wheel 8 can drive the second belt wheel 801 to rotate; the second pulley 801 can thus be able to bring the antenna into rotation. As shown in fig. 7, the elastic plate mechanism 12 is used to move the sliding block 1001 to the top end of the sliding rail by the rotating plate 1203 via the tension spring 1202 pushing against the horizontal plate 1005, and then the horizontal plate 1005 presses the rotating plate 1203 to compress the tension spring 1202, so that the rotating plate 1203 can rotate from the lower end to the upper end of the horizontal plate 1005 without being jammed.

The execution process of the mechanism is that after the first motor 2 is started, the moving pipe 501 and the antenna rod 502 are driven to extend, and meanwhile, the PU belt 802 is gradually driven to be tightened; when the antenna rod 502 is fully extended, the fourth motor is started to clamp the fixed pipe 5 and the movable pipe 501 to prevent falling off; meanwhile, the PU belt 802 is tightened, and the first motor 2 can drive the antenna to rotate, so that the antenna obtains stronger signal collection capability.

As shown in fig. 2, after the second motor 13 is started, the driving revolving door 14 is opened; meanwhile, the fourth bevel gear 1302 is driven to drive the third bevel gear 1602 to rotate along the sixth rotating shaft 1301, so that the first connecting rod 16 is driven to rotate; the first connecting rod 16 drives the second connecting rod 17 to enable the moving seat 1402 to carry the long rod 1403 and the fixed disk 15 to move, and the long rod 1403 is rotatably connected with the fixed disk 15 to ensure that the fixed disk 15 is in contact with the roof cover.
