[0002] Vehicle-mounted antennas can receive signals from satellites, radio towers and other transmission sources, and convert them into electrical signals for transmission to vehicle-mounted devices, such as vehicle navigation and vehicle entertainment systems, to improve the stability and accuracy of vehicle communication, navigation, entertainment and other functions.

[0003] There are still some shortcomings in the currently practical vehicle-mounted antennas: during the use of existing vehicle-mounted antennas, the antennas are installed vertically upward on the vehicle, so the vehicle-mounted antennas are not facing the satellite or radio tower. Under normal use, the signal reception is less affected. When affected by factors such as terrain, weather, buildings, and man-made interference, the signal attenuation will occur. At this time, the signal reception effect of the vehicle-mounted antenna is poor. In addition, when the vehicle is driving, the uneven road surface or improper operation of the driver will cause the body to shake greatly, so the vehicle-mounted antenna will also be vibrated, which can easily cause damage to the receiving elements inside the vehicle-mounted antenna.

[0020] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0021] See also Figure 1-4 According to an embodiment of the utility model, a Beidou navigation vehicle-mounted antenna includes a mounting base plate 1, which is located at the bottom of the entire device and is used to be fixed on the vehicle. A shock absorbing mechanism 2 is provided above the mounting base plate 1, and a protective box 3 is installed above the shock absorbing mechanism 2. A steering mechanism 4 is installed inside the protective box 3, and a long rod antenna 5 is installed on the steering mechanism 4 and extends from a through hole opened in the top center of the protective box 3.

[0022] Among them, the mounting base plate 1 is fixedly installed on the vehicle, so when the vehicle vibrates, the shock absorbing mechanism 2 will separate the mounting base plate 1 and the protective box 3 for shock absorption, and the steering mechanism 4 drives the long pole antenna 5 above to turn to improve the signal receiving effect.

[0023] In this embodiment, the shock absorbing mechanism 2 includes a pair of slide grooves 6 respectively opened on the top of the installation base plate 1 and around the bottom of the protective box 3. A slide rod 7 is fixedly installed between the side walls of the slide groove 6. A first slider 8 passes through and is slidably connected to the slide rod 7. A telescopic sleeve 9 is fixedly installed between the middle parts of the upper and lower ends of the first slider 8. The outer side of the telescopic sleeve 9 is wrapped with a first spring 10 and is fixedly connected to the first slider 8.

[0024] Among them, the slide groove 6 is used to install the slide rod 7 and also plays a certain limiting role on the first slide block 8 and the second slide block 13. The function of the telescopic sleeve 9 is to prevent the relative surfaces of the first slide block 8 at the upper and lower ends from being misaligned. When the vehicle vibrates, the two will move relative to each other, thereby squeezing or stretching the first spring 10 to achieve shock absorption.

[0025] In this embodiment, a T-shaped bracket 11 is fixedly installed in the middle of the bottom of the protective box 3. The cross bar of the T-shaped bracket 11 is located at the bottom and its two ends are connected to one end of the pull rod 12 through a rotating member. The other end of the pull rod 12 is connected to the top of the second slider 13 through a rotating member. A second spring 14 is fixedly connected between the second slider 13 and the first slider 8 and wraps the slide rod 7.

[0026] When the vehicle vibrates, the T-shaped bracket 11 will also move relative to the mounting base plate 1, thereby driving the pull rod 12 to move, and further causing the second slider 13 to move to squeeze or stretch the second spring 14 to achieve a shock-absorbing effect.

[0027] In this embodiment, the steering mechanism 4 includes a mounting block 15 fixedly mounted at the bottom of the long rod antenna 5, a rotating rod 16 passes through and is fixedly mounted on the middle of the side of the mounting block 15, both ends of the rotating rod 16 are rotatably mounted on the side plate 17 through bearings, and the bottom of the side plate 17 is fixedly mounted on the rotating platform 18.

[0028] The rotating rod 16 can drive the mounting block 15 to rotate 180 degrees, so that the mounting block 15 drives the long pole antenna 5 to swing in the vertical direction, and when the rotating platform 18 rotates, it drives the long pole antenna 5 to rotate 360 ​​degrees in the horizontal direction.

[0029] In this embodiment, a first cone wheel 19 is fixedly mounted on the rotating rod 16, a rotating drum 20 passes through and is fixedly mounted on the bottom center of the rotating table 18, the axis of the rotating drum 20 passes through from top to bottom and is rotatably connected to a rotating shaft 21 through a bearing, the upper end of the rotating shaft 21 passes through the rotating table 18 and is fixedly mounted with a second cone wheel 22, and the second cone wheel 22 engages with the first cone wheel 19.

[0030] The rotating shaft 21 drives the second cone wheel 22 to rotate, thereby driving the first cone wheel 19 to rotate, and further driving the rotating rod 16 to rotate. When the rotating drum 20 rotates, it drives the rotating platform 18 to rotate together.

[0031] In this embodiment, a first turbine 23 is passed through and fixedly installed on the bottom of the rotating drum 20, a second turbine 24 is fixedly installed on the bottom of the rotating shaft 21 passing through the rotating drum 20, and a fixed drum 25 is rotatably connected to the outer side of the rotating drum 20 through a bearing, and the middle part of the side wall of the fixed drum 25 is fixedly connected to the inner wall of the protective box 3 through a connecting rod, the first turbine 23 and the second turbine 24 are respectively engaged with a pair of worm rods 26, and the ends of the pair of worm rods 26 are respectively installed on the output ends of a pair of motors 27, and the motors 27 are fixedly installed on the inner bottom of the protective box 3.

[0032] A pair of motors 27 drives the first turbine 23 and the second turbine 24 to rotate respectively through the worm 26 . The first turbine 23 drives the drum 20 to rotate, and the second turbine 24 drives the shaft 21 to rotate.

[0033] In specific application, firstly, the vehicle-mounted antenna device is installed on the vehicle through the installation base plate 1, and a pair of motors 27 are started, which respectively drive the first turbine 23 and the second turbine 24 to rotate through the worm rod 26. The first turbine 23 drives the rotating drum 20 to rotate, and the second turbine 24 drives the rotating shaft 21 to rotate. When the rotating drum 20 rotates, it drives the rotating table 18 to rotate together. When the rotating table 18 rotates, it drives the long rod antenna 5 to rotate 360 ​​degrees in the horizontal direction. The rotating shaft 21 drives the second cone wheel 22 to rotate, thereby driving the first cone wheel 19 to rotate, and then drives the rotating rod 16 to rotate. The rotating rod 16 can drive the mounting block 15 to rotate 180 degrees, so as to achieve the effect of the rotation of the long rod antenna 5 in the horizontal direction. The mounting block 15 drives the long pole antenna 5 to swing in the vertical direction, thereby realizing multi-angle adjustment of the long pole antenna 5 and improving the signal reception effect. When the vehicle is bumpy, the mounting base plate 1 will also fluctuate up and down relative to the protection box 3, so that the mounting base plate 1 is close to or away from the T-shaped bracket 11, thereby driving the pull rod 12 to move, and then the second slider 13 moves to squeeze or stretch the second spring 14 to achieve shock absorption. At the same time, the first slider 8 at the lower end of the telescopic sleeve 9 will move up and down, thereby squeezing or stretching the first spring 10 to achieve shock absorption. Therefore, it can well protect the receiving components inside the vehicle-mounted antenna and improve its service life.
