DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For the purpose of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Embodiment 1

[0027] The present invention provides a mobile communication device, such as Figures 1 to 7 shown, including a housing 1. On one side of the inner wall of the housing 1, a fixed seat 2 is fixedly installed. On one side of the fixed seat 2, a motor 3 is fixedly installed. The output shaft of the motor 3 is fixedly installed with a worm 4. On one side of the inner wall of the housing 1, a first rack 5 is slidably installed. On one side of the inner wall of the housing 1, two first brackets 6 are fixedly installed. Between the two first brackets 6, a first rod 8 is rotatably installed. A first sprocket 9 is fixedly sleeved on the outer surface of the first rod 8. At the top end of the inside of the housing 1, two second brackets 10 are fixedly installed. Between the two second brackets 10, a second rod 11 is rotatably connected. At both ends of the outer surface of the second rod 11, a first gear 12 is fixedly installed. Inside one side of the housing 1, a rotating rod 13 is rotatably installed. An antenna 14 is fixedly installed in the middle of the outer surface of the rotating rod 13. At both ends of the outer surface of the rotating rod 13 at the position inside the housing 1, a second gear 15 is fixedly installed. The outer surface of the second gear 15 meshes with the outer surface of the first gear 12.

[0028] As Figure 2 and Figure 6 shown, on one side of the inner wall of the housing 1, a third bracket 16 is fixedly installed. Inside the third bracket 16, a third rod 17 is rotatably installed. One end of the third rod 17 is fixedly installed with a second worm gear 18. The outer surface of the second worm gear 18 meshes with the outer surface of the worm 4. The other end of the third rod 17 is fixedly installed with a third gear 19. On one side of the inner wall of the housing 1, a sliding seat 20 is fixedly installed. Inside the sliding seat 20, a clamping sleeve 21 is slidably installed. On one side of the inner wall of the housing 1, two foot seats 35 are fixedly installed. Between the two foot seats 35, at the position of one end of the clamping sleeve 21, the same second rack 22 is slidably connected. The outer surface of the second rack 22 meshes with the outer surface of the third gear 19. By driving the worm 4 to rotate through the motor 3, the worm 4 drives the second worm gear 18 to rotate, so that the second worm gear 18 drives the third gear 19 to rotate through the third rod 17, so that the third gear 19 drives the second rack 22 to slide along the horizontal direction of the two foot seats 35.

[0029] As Figure 2 and Figure 6As shown in the figure, a fourth support 23 is fixedly installed on one side of the inner wall of the housing 1. A fourth rod 24 is rotatably installed inside the fourth support 23. One end of the fourth rod 24 is fixedly installed with a first worm gear 25, and the outer surface of the first worm gear 25 meshes with the outer surface of the worm 4. A fourth gear 26 is rotatably installed on one side of the inner wall of the housing 1. The outer surface of the first rack 5 meshes with the outer surface of the fourth gear 26. The fourth gear 26 and the fourth connecting rod are rotationally connected through a first bevel gear transmission structure. A fifth gear 28 is rotatably installed at the edge position of one end of the first rack 5 on one side of the inner wall of the housing 1. The fifth gear 28 and the first connecting rod are rotationally connected through a second bevel gear transmission structure. The motor 3 drives the worm 4 to rotate. The rotation of the worm 4 drives the first worm gear 25 to rotate. The first worm gear 25 drives the first bevel gear transmission structure 27 to rotate through the fourth rod 24. The rotation of the first bevel gear transmission structure 27 drives the fourth gear 26 to rotate, so that the rotation of the fourth gear 26 drives the first rack 5 to move. Through the rotation of the fifth gear 28, the fifth gear 28 drives the first rod 8 to rotate through the second bevel gear transmission structure 29.

[0030] As Figure 2 and Figure 7 shown in the figure, a second sprocket 30 is fixedly sleeved in the middle of the outer surface of the second rod 11. The same toothed chain belt 31 is meshingly installed between the outer surfaces of the second sprocket 30 and the first sprocket 9. Through the toothed chain belt 31, the first sprocket 9 and the second sprocket 30 can be driven. When the first sprocket 9 rotates, it can drive the second sprocket 30 to rotate through the transmission of the toothed chain belt 31.

[0031] As Figure 6 and Figure 7 shown in the figure, the opposite ends of the second rack 22 and the bushing 21 are both inclined surfaces. The horizontal distance on both sides of the second rack 22 gradually becomes larger in the direction of the worm 4. The inclined surface on one side of the bushing 21 fits with the second rack 22. By moving the second rack 22, the second rack 22 can squeeze the bushing 21 during the movement, thereby pushing the bushing 21 to slide.

[0032] As Figure 6 and Figure 7 shown in the figure, fixing blocks 32 are fixedly installed at the top and bottom positions on one side of the bushing 21. Springs 33 are fixedly installed on one side of the two fixing blocks 32. One end of the two springs 33 is connected to the inner wall of the housing 1. Through the elastic restoration of the springs 33, the bushing 21 can be pushed to move, so that the bushing 21 returns to its original state.

[0033] As Figure 6 and Figure 7 shown in the figure, a waterproof sleeve 34 is fixedly installed inside the sliding seat 20. Through the waterproof sleeve 34, liquid is prevented from entering the inside of the housing 1 and affecting the use inside the housing 1.

[0034] As Figure 6 andFigure 7 As shown, a sliding channel is provided at the bottom end of one side of the housing 1. The inner wall of the sliding channel fits with the outer surface of the ferrule 21, providing space for the ferrule 21 through the sliding channel, so that the ferrule 21 can fix the antenna 14.

[0035] As Figure 3 and Figure 4 As shown, a chute is provided inside the first rack 5. Two fixing columns 7 are fixedly installed at the middle position inside the chute on the inner wall of the housing 1. When the first rack 5 slides to the position of the fifth gear 28, the outer surface of the first rack 5 meshes with the outer surface of the fifth gear 28. The first rack 5 is limited by the fixing columns 7, so that the first rack 5 can mesh with the fifth gear 28 after sliding.

[0036] Working principle: The motor 3 drives the worm 4 to rotate counterclockwise. The worm 4 drives the second worm gear 18 to rotate, so that the second worm gear 18 drives the third gear 19 to rotate through the third rod 17, so that the third gear 19 drives the second rack 22 to slide along the horizontal direction of the two pedestals 35. The second rack 22 can squeeze the ferrule 21 during the movement, thereby pushing the ferrule 21 to slide. During the sliding process of the ferrule 21, the spring 33 is squeezed, and the spring 33 deforms and contracts. At the same time, the inner wall of the ferrule 21 is separated from the antenna 14, so that the antenna 14 can rotate. While the worm 4 rotates, the worm 4 rotates to drive the first worm gear 25 to rotate. The first worm gear 25 drives the first bevel gear transmission structure to rotate through the fourth rod 24. The rotation of the first bevel gear transmission structure makes the fourth gear 26 rotate, so that the fourth gear 26 rotates to drive the first rack 5 to move. After the first rack 5 moves, it can mesh with the fifth gear 28, so that the fifth gear 28 rotates. Through the rotation of the fifth gear 28, the fifth gear 28 drives the first rod 8 to rotate through the second bevel gear transmission structure. The first rod 8 rotates to drive the first sprocket 9 to rotate. The first sprocket 9 drives the second sprocket 30 to rotate through the toothed chain belt 31. The second sprocket 30 rotates to drive the second rod 11 to rotate. The second rod 11 rotates to drive the first gear 12 to rotate. The first gear 12 drives the rotating rod 13 to rotate through the second gear 15, so that the rotating rod 13 drives the antenna 14 to rotate, so that the antenna 14 is opened and can receive radio signals. When the antenna 14 is not needed, the motor 3 is started to rotate clockwise, so that the antenna 14 rotates back to its original state. At the same time, the second rack 22 returns to its original position, so that the second rack 22 loses the extrusion on the ferrule 21. When the ferrule 21 loses the extrusion, the elastic recovery of the spring 33 can push the ferrule 21 to move, so that the ferrule 21 returns to its original state, so that the inner wall of the ferrule 21 fits with the antenna 14, and the ferrule 21 cannot be deformed due to collision.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
