Description

Technical Field

[0001] This invention relates to the field of mobile communication equipment technology, and more specifically, to a mobile communication stereo antenna device. Background Technology

[0002] Communication has different interpretations in different contexts. After the advent of radio wave communication, communication was simply interpreted as the transmission of information, referring to the transmission and exchange of information from one place to another, with the purpose of transmitting messages. However, communication has continuously advanced human civilization as the demands for message transmission have increased with the development of social productivity. Among various communication methods, the method of transmitting messages using "electricity" is called telecommunications. This type of communication is characterized by speed, accuracy, and reliability, and is almost unrestricted by time, location, space, and distance, thus experiencing rapid development and widespread application.

[0003] Existing communication 3D antennas are generally fixed and cannot be easily adjusted according to needs. Antennas that can be adjusted usually use multi-section hinged rods. Although this design can enable multiple antennas to move and extend simultaneously, the hinged rods are easily affected by wind and sand outdoors, causing movement to become sluggish and having a short lifespan. In addition, the adjustable antennas are prone to shaking in windy weather. Summary of the Invention

[0021] (1) Therefore, the triangular antenna connecting rod with the beveled arc concave design and the combination design with inserts and slots that can rotate in both directions in this invention not only enables the antenna to be locked in windy weather without shaking, but also overcomes the defects of traditional multi-hinged connecting rods that are prone to wind and sand jamming and have short lifespan.

[0022] (2) In this scheme, hold the first handle, open the first handle, hold the second handle, remove the square metal plate, insert the second hexagonal metal block into the hexagonal slot, hold the crank handle, crank the crank handle, the fourth shaft starts to rotate, the rotation of the fourth shaft drives the two trapezoidal gears to rotate, the rotation of the two trapezoidal gears drives the second shaft to rotate, the rotation of the second shaft drives the circular metal plate to rotate, the rotation of the circular metal plate drives the three fan-shaped metal plates to rotate, the three fan-shaped metal plates and the three triangular metal plates are squeezed, the three triangular metal plates are pushed outward, the three triangular metal plates move outward and drive the three telescopic plates and the three antennas to move outward, finally realizing the increase in the distance between the three antennas, realizing the function of enhancing signal coverage. When the position of the three antennas is appropriate, fix the position of the hexagonal slot by hand, keep the position of the hexagonal slot unchanged, remove the second hexagonal metal block, insert the first hexagonal metal block into the hexagonal slot, when the square metal plate is stuck in the square metal box, the fourth shaft is fixed, realizing the fixation of the position of the three antennas.

[0023] (3) This scheme is designed to allow the three antennas to move toward one end that is closer to each other, which makes it easier to reduce the signal coverage of the three antennas and achieve the effect of adjusting the signal coverage.

[0035] Example:

[0036] Please see Figure 1-5 A mobile communication stereo antenna device includes a base 1, a support column 3 fixedly connected to the upper end of the base 1, a cylindrical mounting box 8 fixedly connected to the upper end of the support column 3, two annular fixing plates 4 fixedly connected to the inner wall of the support column 3, a first limiting plate 5 disposed between the two annular fixing plates 4, a first rotating shaft 6 fixedly connected to the upper end of the first limiting plate 5, a third rotating shaft 17 fixedly connected to the upper end of the first rotating shaft 6, a second rotating shaft 7 fixedly connected to the upper end of the third rotating shaft 17, the upper end of the second rotating shaft 7 penetrating through the lower end of the cylindrical mounting box 8 and fixedly connected to a second limiting plate 10, a circular metal plate 11 fixedly connected to the upper end of the second limiting plate 10, three evenly distributed fan-shaped metal plates 12 fixedly connected to the circumferential surface of the circular metal plate 11, three evenly distributed square holes 15 drilled on the circumferential surface of the cylindrical mounting box 8, telescopic plates 13 movably inserted into each of the three square holes 15, and triangular metal plates 14 fixedly connected to the adjacent ends of the three telescopic plates 13. Antennas 16 are fixedly connected to the ends of the three telescopic plates 13 that are far apart from each other. Three triangular metal plates 14 are matched with three fan-shaped metal plates 12 respectively. First limiting blocks 33 are provided on the left and right sides of the three telescopic plates 13. Six first limiting blocks 33 are fixedly connected to the circumferential surface of the cylindrical mounting box 8. Limiting grooves 39 are carved on the left end of each of the six first limiting blocks 33. First sliding grooves 35 are carved on the upper and lower inner walls of the six limiting grooves 39. First sliding rods 36 are slidably connected in each of the twelve first sliding grooves 35. Second sliding rods 37 are fixedly connected between the two first sliding rods 36 in each first limiting block 33. One end of each of the six second sliding rods 37 is fixedly connected to the telescopic plate 13. Springs 34 are fixedly connected to the ends of the six second sliding rods 37 that are far apart from the cylindrical mounting box 8. The other end of each of the six springs 34 is fixedly connected to the inner wall of the limiting groove 39. A rocking mechanism is provided on the right side of the third rotating shaft 17. A protection mechanism is provided on the right side of the support column 3.

[0037] The inclined edge of the triangular metal plate 14 is curved and smoothly concave. Multiple inclined strips of different lengths are provided on the side of each fan-shaped metal plate 12 away from the curved inclined edge of the triangular metal plate 14. Multiple slots are provided on the right-angled side of the triangular metal plate 14, and the inclined strips are inserted into these slots. This design allows for adjustment of different extension and retraction degrees through a smooth contact pushing method, eliminating the need for multi-stage hinged linkages. This design also ensures safety by preventing significant shaking during strong winds, greatly enhancing safety. Specifically, during strong winds, the first rotating shaft 6 and the circular metal plate 11 are controlled to rotate in opposite directions towards the triangular metal plate 14. The curved edge of plate 14 is completely disengaged from the fan-shaped metal plate 12, so that the side of the three fan-shaped metal plates 12 with the insert strip is inserted into the slot on the nearest right-angle side. Then, the first rotating shaft 6 is locked, thereby locking each antenna 16 as well. This ensures that the antennas 16 will not shake even in windy weather. In the above structure, while ensuring that there is no shaking, the antennas can be smoothly pushed without the need for a hinged linkage mechanism. Since the rotation of the first rotating shaft 6 exists within the protective box 23 and the support column 3, the problem of mud and sand jamming that is common with multi-stage hinged linkages is avoided.

The metal plates 12 cooperate with each other, with the fan-shaped metal plate 12 pressing against the triangular metal plate 14 to move the telescopic plate 13. The square hole 15 facilitates the insertion of the telescopic plate 13. The antenna 16 is for transmitting and receiving signals.

[0049] For details, please refer to Figure 1-2 The base 1 has three evenly distributed fixing feet 2 fixedly connected to its circumferential surface. Each of the three fixing feet 2 has a round hole at its upper end, and each of the three round holes has a mounting screw that can be movably inserted into it.

[0050] In this embodiment, three evenly distributed fixing feet 2 are fixedly connected to the circumferential surface of the base 1. The upper end of each of the three fixing feet 2 is drilled with a round hole, and a mounting screw is movably inserted into each of the three round holes, which helps to increase the stability and safety of the device.

[0051] For details, please refer to Figure 2 A limiting ring 9 is fixedly connected to the upper part of the circumferential surface of the second rotating shaft 7, and the limiting ring 9 is located at the lower part of the cylindrical mounting box 8.

[0052] In this embodiment, a limiting ring 9 is fixedly connected to the upper part of the circumferential surface of the second rotating shaft 7, and the limiting ring 9 is located at the lower part of the cylindrical mounting box 8, which facilitates the stable rotation of the second rotating shaft 7 and prevents the second rotating shaft 7 from wobbling left, right, front and back.

[0053] For details, please refer to Figure 1 , Figure 4 and Figure 5 The other end of each of the six first sliding rods 36 is fixedly connected to a second limiting block 38, and the height of each of the six second limiting blocks 38 is greater than the height of the six limiting grooves 39.

[0057] Holding the first handle 25, open the first handle 25. Holding the second handle 26, remove the square metal plate 27. Insert the second hexagonal metal block 29 into the hexagonal slot 21. Holding the crank handle 32, crank the crank handle 32. The fourth rotating shaft 19 begins to rotate. The rotation of the fourth rotating shaft 19 drives the two trapezoidal gears 18 to rotate. The rotation of the two trapezoidal gears 18 drives the second rotating shaft 7 to rotate. The rotation of the second rotating shaft 7 drives the circular metal plate 11 to rotate. The rotation of the circular metal plate 11 drives the three fan-shaped metal plates 12 to rotate. The three fan-shaped metal plates 12 and the three triangular metal plates 14 are pressed together. The triangular metal plate 14 is pushed outward, and the outward movement of the three triangular metal plates 14 drives the three telescopic plates 13 and the three antennas 16 to move outward, ultimately increasing the distance between the three antennas 16 and enhancing signal coverage. When the positions of the three antennas 16 are appropriate, the position of the hexagonal slot 21 is fixed by hand, keeping the position of the hexagonal slot 21 unchanged. The second hexagonal metal block 29 is removed, and the first hexagonal metal block 28 is inserted into the hexagonal slot 21. When the square metal plate 27 is stuck in the square metal box 22, the fourth rotating shaft 19 is fixed, thus fixing the position of the three antennas 16.

[0058] In windy weather, the first rotating shaft 6 and the circular metal plate 11 are controlled to rotate in the opposite direction until the arc-shaped hypotenuse of the triangular metal plate 14 is completely disengaged from the fan-shaped metal plate 12. This allows the side of the three fan-shaped metal plates 12 with inserts to be inserted into the slots on the nearest right-angled side. Then, the first rotating shaft 6 is locked, thereby locking each antenna 16 as well. This ensures that the antennas 16 will not shake even in windy weather. In the above structure, while ensuring that there is no shaking, the antennas can be smoothly pushed without the need for a hinged linkage mechanism. Since the rotation of the first rotating shaft 6 exists inside the protective box 23 and the support column 3 and does not directly contact the external environment, the problem of mud and sand jamming that is common with multi-stage hinged linkages is avoided.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
