[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of systems consistent with certain aspects of the present invention, as detailed in the appended claims.

[0026] In order to solve the problem that the existing technology of antenna retraction and extension is not intelligent enough, this embodiment provides an automatic retraction and extension mechanism, such as Figure 1 As shown, the mechanism is arranged in the antenna cabin 1. The antenna cabin 1 is a metal frame and is the load-bearing component of the entire mechanism, providing support for the entire structure. The upper portion of the antenna cabin has a cover that covers the entire interior of the antenna cabin. The automatic retraction and extension mechanism includes two or more symmetrically arranged guide rails 4, an active synchronous wheel 12, and a driven synchronous wheel 14. Two or more guide rail supports 2 and guide rail support limiters 3 are fixed diagonally to the outer ends of the two or more guide rails 4. The two or more guide rail supports 2 and guide rail support limiters 3 are fixed in the antenna cabin 1.

[0027] Specifically, the two guide rail supports 2 and the two guide rail support limits 3 are fixed inside the antenna cabin 1 by screws; both ends of the two guide rails 4 are fixed to the guide rail supports 2 and the guide rail support limits 3 by screws respectively, and the movement of the entire mechanism is realized on the guide rails.

[0028] The guide rail 4 is provided with a sliding assembly; the antenna box 7 moves on the guide rail 4 through the sliding assembly, specifically, the sliding assembly includes a slider plate 5 and a slider 6. The bottom of the antenna cabin 1 is fixedly connected to the slider plate 5, and the slider block 5 moves on the guide rail 4 along with the slider 6.

[0029] This mechanism has two antenna boxes 7 , each of which has a slider plate 5 and a slider 6 .

[0030] The power of the mechanism is provided by a power pack 8 fixed in the antenna cabin 1, and the power pack 8 is fixed to the bottom of the antenna cabin 1 by screws;

[0031] The output end of the power group 8 rotates coaxially with the output shaft 9 through a flat key, and the other end of the output shaft 9 rotates coaxially with the input end bearing 10, and the input end bearing 10 is fixed to the bottom of the antenna cabin 1; the input end bearing 10 is fixed to the bottom of the antenna cabin 1 by screws.

[0032] The active synchronous wheel 12 rotates synchronously with the output shaft 9 through a flat key, and the active synchronous wheel 12 drives the driven synchronous wheel 14 to rotate through a synchronous belt 13; support end bearings 15 are provided on both sides of the driven synchronous wheel 14, and the support end bearings 15 are fixed to the bottom of the antenna cabin 1; the two support end bearings 15 are fixed to the bottom of the antenna cabin 1 by screws, and their function is to ensure smooth rotation of the driven pulley 14;

[0033] The short shaft 16 is located between the two support end bearings 15, and is mounted on the driven synchronous wheel 14. The antenna box 7 is connected to the synchronous belt seat 17. Specifically, the synchronous belt seat 17 is fixed to the antenna box 7 by screws.

[0034] The synchronous belt seat 17 is connected to the synchronous belt 13 through the synchronous belt lock seat 18.

[0035] Furthermore, the input end bearing 10 is fixed to the bottom of the antenna cabin 1 by fixing screws 11, and a bearing retaining ring is also provided at the input end bearing 10. The bearing retaining ring and the fixing screws 11 at the power group 8 prevent the output shaft 9 from axial movement.

[0036] like Figure 1 The figure shows the state of not leaving the cabin. When leaving the cabin is necessary, the power group 8 outputs power through the output shaft 9 after receiving the command, drives the active synchronous wheel 12 to rotate, and then drives the synchronous belt 13 to move. The two antenna boxes 7 are respectively connected to the upper and lower belts of the synchronous belt 13 through the synchronous belt seat 17 and the synchronous belt lock seat 18; so when the synchronous belt 13 moves, the two antenna boxes 7 move to the left and right sides at the same time. After the antenna box 7 moves to the specified position, the impact block 24 at the lower end of the antenna box 7 contacts the guide rail support limit 3, and the two antenna boxes 7 continue to move, triggering the internal automatic rotation mechanism to flip the antenna until the antenna is completely vertical, as shown. Figure 2 and Figure 3As shown, the power group 8 rotates in the opposite direction, the lower end bumpers 24 of the two antenna boxes 7 gradually separate from the guide rail support limiter 3, the antenna flips to a horizontal state, and the two antenna boxes 7 move in the opposite direction and return to the inside of the antenna cabin 1.

[0037] At the same time, the automatic retracting and extending mechanism provided by this embodiment only requires one power source, which reduces the probability of failure, saves costs, and greatly increases reliability.

[0038] This embodiment exemplifies two groups of antennas (four antennas), but by changing the length or number of the output shafts 9, increasing the number of guide rails 4, sliders 6, etc., more groups of antennas can be brought in and out synchronously.

[0039] In addition, the embodiment of the present invention further provides an automatic rotation mechanism, which is arranged in the antenna box 7. The antenna box 7 is a load-bearing part of the entire mechanism and provides support for the entire structure. An automatic rotation mechanism includes a collision block 24, a connecting rod 25, a secondary connecting rod 27, a major axis 28, a minor axis 211, and two component seats 212. The collision block 24 is fixed to the upper part of the slider 6 and extends to the outside of the antenna box 7. A collision block protrusion is provided; the collision block 24 slides along the track together with the slider 6, and the connecting rod 25 is connected to the collision block 24 by a pin 1 61 and can rotate relative to the pin 61; the secondary connecting rod 27 is connected to the other end of the connecting rod 25 by a pin 2 62, and both can rotate around the pin 62;

[0040] The long shaft 28 is fixed to both sides of the antenna box 7 through two first seat bearings 29, and the long shaft 28 can be rotated by the seat bearings 29;

[0041] A torsion spring 216 is sleeved on the outside of the long axis 28. The hook side of the torsion spring 216 is fixed to the antenna rod 210, and the other end of the torsion spring 216 contacts the bottom of the antenna box 7.

[0042] The short shaft 211 is fixed to both sides of the antenna box 7 through the second seat bearing 291 and the seat bearing 213, and can be rotated;

[0043] The two antenna rods 210 are coaxially fixed to the major axis 28 and the minor axis 211, respectively, and are specifically fixed to the major axis 8 and the minor axis 11 by screws. The other ends of the two antenna rods 210 are located in the notches on both sides of the secondary connecting rod 27, and are connected to the secondary connecting rod 27 by the third pin 63 and the fourth pin 64, respectively, and can rotate around the third pin 63 and the fourth pin 64.

[0044] Furthermore, the other ends of the long shaft 28 and the short shaft 211 are coaxially connected to two component seats 212, and the two component seats 212 are fixed to the long shaft 28 and the short shaft 211 respectively by screws; they can rotate synchronously with the long shaft 28 and the short shaft 211 respectively, and the other end of the component seat 212 is used to fix the components 214 and 215 that need to rotate synchronously.

[0045] The two antenna rods 210 are coaxially connected to the ends of the secondary connecting rod 27, which ensures that the two antenna rods rotate at the same angle during movement, thereby making the major axis 28 and the minor axis 211 rotate at the same angle; at the same time, because the two component seats 212 rotate synchronously with the major axis 28 and the minor axis 211 respectively, the components 214 and 215 ultimately rotate at the same angle, achieving synchronous rotation.

[0046] like Figure 4 、 Figure 5 As shown, pull the impact block 24 to make it and the slider 6 slide to the left on the guide rail 4. At this time, the secondary connecting rod 27 can be pulled by the connecting rod 25, and the connecting rod 25 and the secondary connecting rod 27 can move to the left and rotate around the pin at the same time. While the secondary connecting rod 27 moves, it drives the antenna rod 210 to rotate around the long axis 28 and the short axis 211 through the bearings. The rotation of the long axis 28 and the short axis 211 drives the two component seats 212, and finally realizes that the components 214 and 215 rotate around the long axis 28 and the short axis 211 at the same time. At this time, the fixed side of the torsion spring 216 rotates with the antenna rod 210, and the other end is in contact with the antenna box 7 and does not move. The torsion spring further accumulates torque.

[0047] Stop pulling the impact block 24. Under the torsion force of the torsion spring 216, the antenna rod 210 rotates in the opposite direction around the long axis 28. The secondary connecting rod 27 drives the antenna rod 210 to rotate around the short axis 211 at the same time, and finally drives the components 214 and 215 to rotate in the opposite direction around the long axis 28 and the short axis 211 to their original positions respectively. Under the torsion force of the torsion spring 216, the component seat 212 is close to the base of the antenna box 7, thereby preventing the components 214 and 215 from rotating at will. At the same time, the impact block 24 and the slider 6 are pulled to the right on the guide rail 4 to slide to their original positions through the connecting rod 25. Finally, the components 414 and 415 rotate automatically and synchronously. Figure 6 、 7 shown.

[0048] By changing the width of the base of the antenna box 7, the position and number of the long axis 28 and the short axis 211, and the length and number of slots of the secondary connecting rod 27, automatic synchronous rotation of multiple target components can be achieved, not limited to the two components 214 and 215 mentioned as examples. The number of torsion springs can also be increased to increase the stability of component fixation.
