[0028] The working principle of this embodiment is as follows:

[0029] Since the first guide rail 31 and the second guide rail 32 are located between the first spherical lens 11 and the second spherical lens 21, and the first feed source 12 is mounted on the first sliding seat 33, and the second feed source 22 is mounted on the second sliding seat 34, the main radiation directions of the first antenna unit 1 and the second antenna unit 2 are arranged in back-to-back relationship, so that the lens antenna has a longer signal coverage distance.

[0030] This embodiment is applied to installation scenarios at locations such as tunnel bends and platforms along the railway. Due to the limitations of the installation environment in these places, the height of the antenna installation location is relatively low, and it is usually not necessary to adjust the antenna's tilt angle. During debugging, the movable seat 37 is driven to slide according to the installation environment, so that the transmission sleeve 36 inserted in the movable seat 37 is driven to move, and then the transmission rod 35 inserted in the transmission sleeve 36 is driven to move, so that the first sliding seat 33 and the second sliding seat 34 are driven to slide at the same time. Since the first guide rail 31 and the second guide rail 32 are both arc-shaped structures, the first sliding seat 33 and the second sliding seat 34 will move away from or approach each other during the sliding process. By adopting a structure in which the transmission rod 35 is inserted in the transmission sleeve 36 and the transmission sleeve 36 is inserted in the movable seat 37, the first sliding seat 33, the second sliding seat 34, and the movable seat 37 can maintain a transmission connection, and then the angle between the main radiation direction of the first antenna unit 1 and the main radiation direction of the second antenna unit 2 can be adjusted, thereby achieving comprehensive signal coverage of the site.

[0031] like Figures 2 to 5 As shown, the base 4 includes a bottom frame 41, a first support plate 42, a second support plate 43, a first support frame 44 and a second support frame 45; the first support plate 42 and the second support plate 43 are arranged side by side on the bottom frame 41, a first slide hole 421 is formed on the first support plate 42, and a second slide hole 431 is formed on the second support plate 43. The first slide hole 421 and the second slide hole 431 are arranged opposite to each other to form a sliding space in combination, and the moving seat 37 is slidably arranged in the sliding space; the first spherical lens 11 is mounted and fixed on the first support plate 42 through the first support frame 44, the second spherical lens 21 is mounted and fixed on the second support plate 43 through the second support frame 45, the first guide rail 31 is mounted and fixed on the first support plate 42, and the second guide rail 32 is mounted and fixed on the second support plate 43. By forming a sliding space between the first support plate 42 and the second support plate 43, the structure of the lens antenna can be made more compact and the occupied space of the lens antenna can be reduced.

[0032] like Figures 2 to 5As shown, the base 4 also includes two first connecting members 46 and two second connecting members 47; one end of each first connecting member 46 is detachably connected and fixed to the first support plate 42, and the other end of each first connecting member 46 forms a first set groove; one end of each second connecting member 47 is detachably connected and fixed to the second support plate 43, and the other end of each second connecting member 47 forms a second set groove; the two ends of the first guide rail 31 are respectively embedded in the first set grooves of the two first connecting members 46 for fixing, and the two ends of the second guide rail 32 are respectively embedded in the second set grooves of the two second connecting members 47 for fixing. Through such a design, the disassembly and installation of the first guide rail 31 and the second guide rail 32 can be made more convenient.

[0033] like Figures 2 to 5 As shown, the base 4 further includes a first limit baffle 48 and a second limit baffle 49, which are both connected and fixed to the first support plate 42 and the second support plate 43, and are both in the sliding space, and are respectively located on opposite sides of the moving seat 37, so that the range of movement of the moving seat 37 is limited between the first limit baffle 48 and the second limit baffle 49. By adding the first limit baffle 48 and the second limit baffle 49, the range of movement of the moving seat 37 can be prevented from being too large, and the first sliding seat 33 can be prevented from being separated from the first guide rail 31, and the second sliding seat 34 can be prevented from being separated from the second guide rail 32, thereby affecting the normal operation of the lens antenna.

[0034] like Figures 2 to 5 As shown, the base 4 also includes a mounting plate 50, which is connected and installed between the first support plate 42 and the second support plate 43; the driving assembly 38 includes two guide rods 381, a screw 382 and a motor 383; the two ends of the screw 382 are rotatably mounted on the first limit baffle 48 and the second limit baffle 49, and the rotation axis of the screw 382 is set along the left and right direction; the two ends of each guide rod 381 are respectively mounted and fixed on the first limit baffle 48 and the second limit baffle 49, and the axis of each guide rod 381 is set along the left and right direction; a guide hole and a screw hole are formed on the movable seat 37, the movable seat 37 is sleeved on the guide rod 381 through the guide hole, and the movable seat 37 is threadedly connected with the screw 382 through the screw hole; the motor 383 is mounted on the mounting plate 50, and the motor 383 is used to drive the screw 382 to rotate. The motor 383 is electrically connected to an external control component via a cable, so as to remotely control the motor 383 and adjust the radiation directions of the first antenna unit 1 and the second antenna unit 2, which is more convenient to operate.

[0035] like Figure 4 and Figure 5As shown, the cross-sectional profile of the first guide rail 31 and the second guide rail 32 is an elliptical structure, the major axis of the elliptical structure of the first guide rail 31 is intersected with the center of the first spherical lens 11, and the major axis of the elliptical structure of the second guide rail 32 is intersected with the center of the second spherical lens 21. With such a structure, the first sliding seat 33 will not rotate relative to the first guide rail 31, and the second sliding seat 34 will not rotate relative to the second guide rail 32, so that the sliding of the first sliding seat 33 and the second sliding seat 34 is more stable. By adopting the cross-sectional profile of the elliptical structure, the first guide rail 31 and the second guide rail 32 can effectively improve the bending resistance of the first guide rail 31 and the second guide rail 32, so that the service life of the first guide rail 31 and the second guide rail 32 is longer, and the stability of the first sliding seat 33 and the second sliding seat 34 when sliding can be improved.

[0036] like Figures 1 to 5 As shown, this embodiment also includes a housing 5, which includes a shell 51, a first cover 52 and a second cover 53. The shell 51 is a cylindrical structure. The first cover 52 is detachably covered and fixed on one end of the shell 51, and the second cover 53 is detachably covered and fixed on the other end of the shell 51, so that the first cover 52, the shell 51 and the second cover 53 are enclosed to form an installation cavity 54; the first antenna unit 1, the second antenna unit 2, the adjustment mechanism 3 and the base 4 are all arranged in the installation cavity 54. Through such a structure, the first antenna unit 1, the second antenna unit 2 and the adjustment mechanism 3 can be prevented from being directly exposed to the external environment, and a dustproof and waterproof protection effect is achieved.

[0037] like Figures 2 to 5 As shown, a plurality of first supporting ribs 521 are formed on the first cover 52, and a plurality of second supporting ribs 531 are formed on the second cover 53; the first supporting ribs 521 and the second supporting ribs 531 are both arc-shaped sheet structures, and the inner arc of the first supporting ribs 521 supports the spherical surface of the first spherical lens 11, and the inner arc of the second supporting ribs 531 supports the spherical surface of the second spherical lens 21. By adding the first supporting ribs 521 and the second supporting ribs 531, the force structure of the first spherical lens 11 and the second spherical lens 21 can be made more reasonable, and the stability of the first spherical lens 11 and the second spherical lens 21 can be improved.

[0038] Example 2

[0039] like Figure 6 and Figure 7Embodiment 2 is a lens antenna for signal coverage along a railway. The difference between Embodiment 2 and Embodiment 1 is that the rotation axis of the screw 382 is arranged along the up-down direction, the axis of each guide rod 381 is arranged along the up-down direction, and the motor 383 is installed on the base frame 41, so that the sliding direction of the movable seat 37 is arranged along the up-down direction, so that the movable seat 37 can simultaneously drive the first sliding seat 33 and the second sliding seat 34 to slide in the vertical direction by sliding, so as to adjust the tilt angle between the main radiation direction of the first antenna unit 1 and the main radiation direction of the second antenna unit 2.

[0040] This embodiment is applied to the installation scenario of the open-air track location along the railway. In these installation sites, in order to improve the coverage of the radio beam, the height of the antenna installation location is relatively high. At this time, according to environmental factors such as the installation height, the first sliding seat 33 and the second sliding seat 34 can be driven to slide up and down by driving the movable seat 37 to slide, so as to adjust the tilt angle between the main radiation direction of the first antenna unit 1 and the main radiation direction of the second antenna unit 2, so as to achieve comprehensive signal coverage of the site.

[0041] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention.
