Description

Technical Field

[0002] An automotive antenna is a device that intercepts high-frequency radio waves transmitted by a transmitting station and transmits them to a receiver of an automotive radio, a vehicle-mounted telephone, or a radio navigation device for demodulating the carrier wave. Characteristics brought by the environmental use: Considering the arbitrary moving use conditions of the vehicle, except for devices such as ETC used in specific places, general vehicle-mounted antennas should be omnidirectional antennas.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] Please refer toFigures 1 to 5 , the present invention provides a technical solution: a multi-network integrated vehicle-mounted antenna, which includes a base 1. A fin cover 2 is arranged on the upper side of the base 1. One end of the fin cover 2 is set as a tip, and a wind guide groove is arranged on the outer side of the fin cover 2. The fin cover 2 includes an outer protective shell 18, and an inner support shell 20 is arranged inside the outer protective shell 18. Double protection is carried out through the outer protective shell 18 and the heat dissipation mechanism 10. An inner strengthening layer 19 is arranged between the inner support shell 20 and the outer protective shell 18. The cross-sectional shape of the inner strengthening layer 19 is set as a honeycomb shape. Support ribs 21 are arranged inside the inner support shell 20. A support cylinder 22 is fixedly connected between the support ribs 21 and the inner support shell 20. A circuit board 23 is arranged inside the lower end of the fin cover 2. A network connection module 24 and a strengthening antenna 25 are arranged on the upper side of the circuit board 23. The upper end of the strengthening antenna 25 is inserted into the inside of the support ribs 21. Multiple network receiving signals are received through the network connection module 24 and the strengthening antenna 25 on the circuit board 23. A heat dissipation mechanism 10 is arranged inside the base 1. The lower side of the circuit board 2 is attached to the heat dissipation mechanism 10. A connection mechanism 3 is arranged at the connection between the base 1 and the fin cover 2.

[0029] As can be seen from the above description, the present invention has the following beneficial effects: the outer protective shell 18, the inner strengthening layer 19, the inner support shell 20 and the support cylinder 22. During use, double protection is carried out through the outer protective shell 18 and the heat dissipation mechanism 10, and the compressive resistance is increased through the honeycomb-shaped inner strengthening layer 19, so as to reduce the deformation of the fin cover 2. And the fin cover 2 is made more stable through the auxiliary support of the support cylinder 22 and the support ribs 21.

[0030] Embodiment Two:

[0031] Please refer to Figures 1 to 5 As shown in the figure, on the basis of Embodiment One, the present invention provides a technical solution: the connection mechanism 3 includes a mounting insertion plate 7 fixed to the lower side of the fin cover 2, a connection slot 6 opened on the upper side edge of the base 1, a pushing block 5 slidably mounted at one end of the connection slot 6, and a knob screw 4 screwed on one end of the base 1. One end of the knob screw 4 is rotatably connected to the pushing block 5 through a bearing. The pushing block 5 is pressed by the knob screw 4 to be clamped on the mounting insertion plate 7 for fixation. The shapes of both ends of the mounting insertion plate 7 are set as triangular shapes. One end of the pushing block 5 and one end of the connection slot 6 are respectively clamped at both ends of the mounting insertion plate 7, so that the pushing block 5 and the connection slot 6 stably fix the mounting insertion plate 7; the connection mechanism 3 further includes a positioning chute 9 opened at one end of the base 1. A sliding insertion block 8 is slidably connected inside the positioning chute 9. The sliding insertion block 8 is fixed to the lower side of one end of the fin cover 2.

[0032] With the above-mentioned connecting mechanism 3, when in use, the fin cover 2 is fixed on the base 1 through the connecting mechanism 3. When the antenna fails and the fin cover 2 needs to be disassembled, just rotate the knob screw 4 to drive the pushing block 5 to slide away from the mounting plug board 7, and then the mounting plug board 7 can be pulled out from the connecting slot 6, so as to disassemble the fin cover 2, which is more convenient when disassembling and assembling the fin cover 2.

[0033] Further, reference can be made to Figure 3 and Figure 4 The heat dissipation mechanism 10 includes a heat absorption copper tube 13 arranged inside the base 1. At both ends of one side of the base 1, an air inlet fan 11 and an air outlet fan 12 are respectively arranged. The air inlet fan 11 and the air outlet fan 12 are respectively communicated with both ends of the heat absorption copper tube 13. The position of the heat absorption copper tube 13 corresponds to the position of the circuit board 23. Heat is absorbed through the heat absorption copper tube 13, and then through the operation of the air inlet fan 11 and the air outlet fan 12, the air flow quickly passes through the heat absorption copper tube 13, so that the heat on the heat absorption copper tube 13 is taken away by the air for heat dissipation; the heat dissipation mechanism 10 further includes a thermally conductive carbon fiber layer 15 arranged outside the heat absorption copper tube 13 and a thermally conductive graphite film 16 arranged on the upper side of the thermally conductive carbon fiber layer 15. The thermally conductive graphite film 16 is attached to the lower side of the circuit board 23. The heat dissipated by the circuit board 23 can be absorbed by the thermally conductive graphite film 16 and conducted horizontally, and then guided to the heat absorption copper tube 13 through the thermally conductive carbon fiber layer 15; a thermally conductive support piece 17 is arranged inside the thermally conductive carbon fiber layer 15, and the thermally conductive support piece 17 supports the heat absorption copper tube 13. A support column 14 is arranged inside one end of the base 1, and the support column 14 supports the lower side of the fin cover 2; the thermally conductive support pieces 17 are evenly installed inside the base 1, and the thermally conductive carbon fiber layer 15 wraps outside the thermally conductive support pieces 17, so that the thermally conductive support pieces 17 are more convenient and stable for heat conduction during use.

[0034] With the above-mentioned heat dissipation mechanism 10, when in use, the heat on the circuit board 23 is absorbed through the horizontal guiding action of the thermally conductive graphite film 16, and then guided to the heat absorption copper tube 13 through the thermally conductive graphite film 16 for absorption. Then, combined with the operation of the air inlet fan 11 and the air outlet fan 12, the air quickly passes through, so that the circuit board 23 can be quickly cooled, and dust is prevented from entering the base 1 and the fin cover 2 and adsorbing on the circuit board 23 to affect heat dissipation.

[0035] Working principle and usage process of the present invention: When in use, fix the base 1 on the roof of the vehicle. The network connection module 24 and the enhanced antenna 25 on the circuit board 23 receive signals from multiple networks, facilitating the use of multiple in-vehicle devices. When in use, the heat generated by the circuit board 23 can be absorbed by the thermal conductive graphite film 16 and conducted horizontally, then guided to the heat absorption copper tube 13 through the thermal conductive carbon fiber layer 15. The heat absorption copper tube 13 absorbs the heat, and then through the operation of the intake fan 11 and the exhaust fan 12, the air flow quickly passes through the heat absorption copper tube 13, and the heat on the heat absorption copper tube 13 is carried away by the air, thus dissipating the heat of the circuit board 23. When in use, when the fin cover 2 is stressed, it can be double-protected by the outer protective shell 18 and the heat dissipation mechanism 10, and the toughness and strength are increased through the support cylinder 22 and the inner reinforcement layer 19, reducing the phenomenon of stress damage. When a fault occurs after long-term use, just manually rotate the knob screw 4 to drive the push block 5 to move away from one end of the installation plug board 7, and then the installation plug board 7 can be pulled out from the connection slot 6, so as to remove the fin cover 2 for internal maintenance.
