[0047] As Figures 3 to 5 shown, the support assembly 30 includes a first folding arm 31, a pull rod 32, and a first support arm 33. One end of the first folding arm 31 is connected to the rotating member 22, and the other end is hinged to the first folding arm 31. One end of the pull rod 32 is hinged to the rotating member 22, and the other end is hinged to the first folding arm 31. The support assembly 30 further includes a second folding arm 34.

The axle 12 is detachably connected to the second folding arm 34. To drive the first folding arm 31 and the second folding arm 34 to fold and deform, the support assembly 30 further includes a first connecting rod (not shown in the figure), a second connecting rod (not shown in the figure), and a folding power element 35. One end of the first connecting rod is hinged to the first folding arm 31, and the other end is hinged to the folding power element 35. One end of the second connecting rod is hinged to the second folding arm 34, and the other end is hinged to the folding power element 35. The end of the folding power element 35 away from the second connecting rod is hinged to the second folding arm 34. The first folding arm 31, the second folding arm 34, the first connecting rod, and the second connecting rod form a four-bar linkage assembly. The first folding arm 31, the second folding arm 34, the pull rod 32, and the rotating member 22 form a four-bar linkage assembly. During use, the folding power element 35 drives the first connecting rod and the second connecting rod to rotate synchronously, causing the first folding arm 31 to rotate around the second folding arm 34. At the same time, since the rotating member 22 is fixed, the first folding arm 31 drives the pull rod 32 to move upward. Then, under the traction of the pull rod 32, the first folding arm 31 and the second folding arm 34 move upward until the first folding arm 31 and the second folding arm 34 are in a straight line. At this time, the second folding arm 34 is perpendicular to the rotating member 22.

[0048] To stretch the first support arm 33, the support assembly 30 further includes a second support arm 36 and a strut 37. One end of the second support arm 36 is fixedly connected to the end of the first support arm 33 away from the first folding arm 31, and one end of the strut 37 is hinged to the end of the first support arm 33 away from the first folding arm 31. The support assembly 30 includes a stretching member 38 and a stretching power element 39. One end of the stretching member 38 is connected to the stretching power element 39, and the other end is connected to the second support arm 36 after passing through the strut 37. The stretching power element 39 is mounted on the rotating member 22, and the stretching power element 39 is used to stretch the stretching member 38 to cause the first support arm 33 to rotate around the first folding arm 31. Optionally, the stretching member 38 is a steel wire rope, and the stretching power element 39 is a winch. During use, the stretching power element 39 shortens the stretching member 38, so that the stretching member 38 drives the first support arm 33 to rotate around the first folding arm 31 until the first support arm 33 and the first folding arm 31 are in a straight line.

[0049] As Figures 6 to 8 shown, the antenna assembly 40 includes a first antenna layer 41, a second antenna layer 42, a first telescopic member 43 and a first telescopic power element (not labeled in the figure). One end of the first antenna layer 41 is connected to the first support arm 33, and one end of the second antenna layer 42 is hinged to the first support arm 33; one end of the first telescopic member 43 is connected to the second antenna layer 42, and the other end is connected to the first antenna layer 41. The first telescopic member 43 can be telescoped to adjust the angle between the first antenna layer 41 and the second antenna layer 42, so as to realize the extension of the second antenna layer 42. The first telescopic power element is connected to the first telescopic member 43, and the first telescopic power element is used to control the telescoping of the first telescopic member 43 to adjust the angle between the first antenna layer 41 and the second antenna layer 42; optionally, one side of the first antenna layer 41 is fixedly connected to the second support arm 36, the first telescopic power element is mounted on the second support arm 36, one end of the first telescopic member 43 is connected to the first telescopic power element, and the other end is connected to the second antenna layer 42; the included angle between the first antenna layer 41 and the second antenna layer 42 is 10 degrees. Further, the first telescopic member 43 is a steel wire rope, and there are six first telescopic members 43 to ensure firm connection; the first telescopic power element is a winch. In other embodiments, the first telescopic power element is mounted on the first antenna layer 41; or, the first telescopic power element is mounted on the second antenna layer 42, one end of the first telescopic member 43 is connected to the first telescopic power element, and the other end is connected to the first antenna layer 41.

[0050] In one embodiment, the antenna assembly 40 further includes a third antenna layer 44, a fourth antenna layer 45, a second telescopic member 46, a second telescopic power element (not shown in the figure), a third telescopic member 47, and a third telescopic power element (not shown in the figure). One end of the third antenna layer 44 and the fourth antenna layer 45 is hinged to the first support arm 33. The second telescopic member 46 connects the third antenna layer 44 and the second telescopic power element. The second telescopic power element is used to stretch the second telescopic member 46 to adjust the angle between the second antenna layer 42 and the third antenna layer 44. The third telescopic member 47 connects the fourth antenna layer 45 and the third telescopic power element. The third telescopic power element is used to stretch the third telescopic member 47 to adjust the angle between the third antenna layer 44 and the fourth antenna layer 45. Optionally, the second telescopic power element is installed on the second antenna layer 42, and the third telescopic power element is installed on the third antenna layer 44. The included angle between the second antenna layer 42 and the third antenna layer 44 and the included angle between the third antenna layer 44 and the fourth antenna layer 45 are both 10 degrees, ensuring the frequency-independent characteristics of each antenna. Further, the second telescopic member 46 and the third telescopic section are both steel wires, and the second telescopic power element and the third telescopic power element are both winches. When it is necessary to deploy and receive or transmit signals, the first telescopic power element extends the first telescopic member 43. Since each antenna layer is fixed by a telescopic member, the second antenna layer 42, the third antenna layer 44, and the fourth antenna layer 45 all rotate around the first support arm 33 until the included angle between the first antenna layer 41 and the second antenna layer 42 is 10 degrees. The third antenna layer 44 and the fourth antenna layer 45 are operated in the same way in turn. The folding process is opposite to the unfolding process. In the folded state, the transportation size can be effectively reduced, and it is convenient for installation and maintenance.

[0051] To achieve automatic control, the vehicle-mounted short-wave antenna 100 further includes a control component (not shown in the figure). The control component is respectively connected to the slewing component 20, the support component 30, and the antenna component 40 in a signal connection.

[0052] The whole machine folding process: As Figure 1 shown, in the transportation state, the rotating member 22 is movably connected to the tractor 11, and the axle 12 is connected to the second folding arm 34 through a pin shaft; the rotating member 22 and the fixed member 21 are at an initial angle and locked; the first swing leg 24, the second swing leg, the third swing leg 25, and the fourth swing leg are all in a folded and contracted state; the support component is installed on the rotating member 22, the support component is in a horizontal state and locked, and the antenna component is hinged to the first support arm 33 and is in a horizontal state.

[0053] After arriving at the destination, as Figure 2As shown, the control component controls the first power element 26, the second power element, the third power element, and the fourth power element to drive the first swing leg 24, the second swing leg, the third swing leg 25, and the fourth swing leg to unfold respectively. The control component controls the first support power element 27, the second support power element, the third support power element, and the fourth support power element to drive the first swing leg 24, the second swing leg, the third swing leg 25, and the fourth swing leg to extend respectively. Then the control component controls the first lifting power element 28, the second lifting power element, the third lifting power element, and the fourth lifting power element to extend and contact the ground, so as to fix each swing leg. At this time, the stretching power element 39 works to retract the stretching member 38, so that the support rod 37 rotates to place around the first support arm 33 and drives the stretching member 38 to be straightened.

[0054] Next, the tractor 11 slightly reverses backward a little. The control component controls the first lifting power element 28, the second lifting power element, the third lifting power element, and the fourth lifting power element to continue to extend. While leveling and fixing the fixing member 21, it also makes the connecting pin of the rotating member 22 and the tractor 11 disengage from the tractor 11, and the tractor 11 drives forward and disengages from the rotating member 22. Remove the connecting pin of the second folding arm 34 and the axle 12, and move the axle 12 backward to disengage from the second folding arm 34.

[0055] As Figure 3 shown, the control component controls the folding power element 35 to extend. The folding power element 35 drives the first connecting rod and the second connecting rod to rotate synchronously, so that the first folding arm 31 rotates around the second folding arm 34. At the same time, since the rotating member 22 is fixed, the first folding arm 31 drives the pull rod 32 to move upward. Then, under the traction of the pull rod 32, the first folding arm 31 and the second folding arm 34 move upward until the first folding arm 31 and the second folding arm 34 are in a straight line. At this time, the second folding arm 34 is perpendicular to the rotating member 22, as Figure 4 . During the process of the folding power element 35 extending, the stretching power element 39 controls the length of the stretching member 38 to keep the stretching member 38 in a straightened state.

[0056] After the first folding arm 31 and the second folding arm 34 are fully unfolded, as Figure 5 shown, the stretching power element 39 shortens the stretching member 38. Thus, the stretching member 38 drives the first support arm 33 to rotate around the first folding arm 31, and at the same time drives the antenna assembly 40 to rotate together until the first support arm 33 and the first folding arm 31 are in a straight line.

[0057] As Figure 6As shown in the figure, when it is necessary to expand and receive or transmit signals, the first telescopic power element elongates the first telescopic member 43. Since each antenna layer is fixed by telescopic members, the second antenna layer 42, the third antenna layer 44, and the fourth antenna layer 45 all rotate around the first support arm 33 until the included angle between the first antenna layer 41 and the second antenna layer 42 is 10 degrees. The third antenna layer 44 and the fourth antenna layer 45 are operated in the same way successively. Figure 7 It is a schematic diagram of the expansion of the third antenna layer. Figure 8 It is a schematic diagram of the expansion of the fourth antenna layer.

[0058] The folding process of the whole machine is exactly the opposite of the unfolding process of the whole machine. That is, first control the third telescopic power element to shorten the third telescopic member 47, fold the fourth antenna layer 45, and the third antenna layer 44 and the second antenna layer 42 are operated in the same way successively; then, elongate the stretching member 38, and the first support arm 33 will drive the antenna assembly 40 to rotate around the first folding arm 31; then, contract the folding power element 35, and the first folding arm 31 and the second folding arm 34 are folded, and at the same time drive the first support arm 33, the second support arm 36 and the antenna assembly 40 to move until they are in a horizontal state. Finally, after connecting the tractor 11 and the axle 12, contract each lifting power element, each support power element and the power element. After each swing leg is contracted and folded, it can be transported on the road.

[0059] It should be noted that the structure proposed by the vehicle-mounted short-wave antenna 100 has been verified by simulation of the ADAMS component and analysis of the PROE component analysis module. Therefore, during the movement process, it only needs to be operated according to the operating procedures. At the same time, the principle of the whole machine component of the vehicle-mounted short-wave antenna 100 is not only limited to the application in the field of vehicle-mounted short-wave antennas 100, but also applicable in other construction machinery fields.

[0060] The above vehicle-mounted short-wave antenna 100 realizes folding and extension through the cooperation of the first folding arm 31, the first support arm 33 and the pull rod 32, and realizes the angle adjustment between the first antenna layer 41 and the second antenna layer 42 through the telescopic movement of the first telescopic member 43. The vehicle-mounted short-wave antenna 100 has a simple structure, can be folded and extended, and is convenient for installation and maintenance.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0062] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
