DETAILED DESCRIPTION

[0046] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0047] Example:

[0048] like Figures 1 to 19 As shown, a vehicle-mounted antenna lifting device includes a slewing mechanism 1, an erecting mechanism 2 and a lifting device 3. The slewing mechanism 1 includes a turntable 11, a turntable bearing 12 and a motor A13. The turntable 11 is connected to the turntable bearing 12, the turntable bearing 12 is connected to the motor A13, and the erecting mechanism 2 and the lifting device 3 are respectively connected to the turntable 11. The lifting device 3 can be arranged at the rear of the vehicle body and not on the same side as the erecting mechanism 2, so as to maintain the balance of the device.

[0049] The turntable 11 is arranged above the turntable bearing 12, and the turntable bearing 12 includes a connecting part A121 and an internal gear 122. The connecting part A121 is annular, and the inner wall of the connecting part A121 is connected to the outer wall of the internal gear 122. The connecting part A121 is fixed on the vehicle body. Two motors A13 are symmetrically arranged, and a reducer A131 is arranged on the motor A13. The output shaft of the reducer A131 is connected to the main gear 132, and the main gear 132 is meshed with the internal gear 122.

[0050] The turntable 11 can be welded by steel plates and square steel pipes. The turntable bearing 12 is selected to have a size similar to the outer diameter of the turntable 11 to withstand a larger overturning torque. Dual motors A13 are symmetrically arranged on the right side of the vehicle body. Each motor A13 is connected to the main gear 132 after two reversals through a reducer A131, and the main gear 132 engages with the turntable bearing.

[0051] The turntable 11 is provided with a connecting groove 111 and a supporting frame 112 . The connecting groove 111 is provided on the bottom surface of the turntable 11 . The turntable 11 is rotatably connected to the internal gear 122 of the turntable bearing 12 via the connecting groove 111 , so that the turntable 11 can rotate on the turntable bearing 12 .

[0052] In the rotary mechanism 1, when the turntable 11 has a large load and a large angular acceleration requirement, the power and torque required by the motor A13 are often large, and the main gear 132 generates a large stress. With the dual motor A13 layout, the two main gears 132 simultaneously bear the turntable torque, which can reduce the maximum torque and maximum stress required by a single main gear 132, reducer A131 and motor A13 when working, and reduce the maximum power required by each motor A13 by about 1 / 2, thereby reducing the size of each motor A13 and reducing the required installation height of the motor A13.

[0053] The erecting mechanism 2 includes an antenna support 21, an antenna bracket 22, a motor B23, an electric cylinder 24, a balancing machine 25 and a support base 26. The antenna support 21 is connected to the turntable 11 through the antenna bracket 22. The motor B23, the electric cylinder 24, the balancing machine 25 and the support base 26 are respectively arranged on the turntable 11. The motor B23 is connected to one end of the electric cylinder 24, and the other end of the electric cylinder 24 is connected to the antenna bracket 22. One end of the balancing machine 25 is connected to the antenna bracket 22.

[0054] The antenna support 21 is installed on the leftmost side of the turntable 11. A large antenna can be set on the antenna support 21 and installed through the antenna bracket 22. The antenna bracket 22 acts as a swivel fulcrum. The erection motor B23 and the synchronous electric cylinder 24 are installed on the left side of the center of the turntable 11. Two balancing machines 25 are placed on the outside of the two electric cylinders 24. During the erection process of the erection mechanism 2, the compressed elastic member A253 in the balancing machine 25 provides thrust, and the elastic member B263 in the support seat 26 also provides upward thrust.

[0055] The motor B23 is provided with a reducer B231, and the output shaft of the reducer B231 is connected to the bevel main gear reduction box 234 through a coupling 232. The bevel main gear reduction box 234 is connected to the electric cylinder 24, thereby driving the electric cylinder 24 to extend and retract. The bevel main gear reduction box 234 is hinged to the turntable 11 through a hinge seat A235, and two electric cylinders 24 are symmetrically arranged.

[0056] The balancing machines 25 are symmetrically arranged in two, and the balancing machine 25 includes a sleeve A251, a sleeve B252 and an elastic member A253. A pressure rod 254 and an elastic member A253 are arranged in the sleeve B252. The sleeve A251 is hinged to the turntable 11 through a hinge seat B255. One end of the sleeve B252 extends into the sleeve A251 for sliding connection. The sleeve B252 is connected to the antenna bracket 22. One end of the elastic member A253 is in contact with the pressure rod 254, and the other end of the elastic member A253 is connected to the inner wall of the sleeve A251. The elastic member A253 can be a spring. The balancing machine 25 and the electric cylinder 24 are arranged at the same hinge point.

[0057] The antenna bracket 22 is provided with an articulated seat C221, an articulated seat D222 and an articulated seat E223. The antenna bracket 22 is articulated to the turntable 11 via the articulated seat C221. The antenna bracket 22 is connected to the electric cylinder 24 via the articulated seat D222. The antenna bracket 22 is articulated to the sleeve B252 of the balancing machine 25 via the articulated seat E223. A groove 211 is provided on the antenna support 21.

[0058] To prevent the lifting device 3 from interfering with the antenna support 21 after lifting the antenna 34 to a high position, the antenna support 21 needs to have a clearance groove 211 at the interference location to ensure that the antenna support 21 rotates within the working angle range (β0~β2) without interfering with the lifting device 3.

[0059] The support seat 26 includes a sleeve C261, a sleeve D262 and an elastic member B263. The sleeve C261 is arranged on the turntable 11. One end of the sleeve D262 extends into the sleeve C261 for sliding connection. The elastic member B263 is arranged in the sleeve C261. One end of the elastic member B263 is connected to the inner wall of the sleeve C261. The other end of the elastic member B263 is connected to the inner wall of the sleeve D262. The elastic member B263 can be a spring. The support seat 26 is arranged on the inner side of the two azimuth motors A13. The antenna bracket 22 can fall on the sleeve D262 on the pressure rods of the two support seats 26 in a horizontal state.

[0060] Due to the total installation height and space limitations of the erection mechanism 2, the horizontal height of the antenna support 21 is very low, and the angle α between the electric cylinder 24 and the antenna support 21 is often very small, resulting in the electric cylinder 24 providing very little upward lifting force to the antenna support 21 during the horizontal erection stage of the antenna support 21, and being unable to lift the antenna support 21. The large thrust electric cylinder is not suitable for the limited installation space. When the antenna support 21 is erected in a horizontal state, the large thrust of the electric cylinder 24 will increase the horizontal component of the thrust of the electric cylinder 24, which may damage the articulated seat D222 and the antenna bracket 22. Therefore, a support seat 26 with a buffering effect is added, which can provide an upward thrust when the antenna support 21 is erected horizontally, and can also play a buffering role and provide a certain supporting force when the antenna support 21 falls back quickly, and provide support for the horizontal state of the antenna support 21. When the antenna bracket 22 is separated from the support base 26 , the force arm of the electric cylinder 24 on the antenna support 21 is still small, so the balancing machine 25 is required to provide auxiliary thrust to complete the rapid erection and fall back of the antenna support 21 .

[0061] Since the balancing machine 25 only provides pressure but not tension, when designing the balancing machine 25, it is necessary to ensure that the electric cylinder 24 does not provide thrust when it changes from thrust to tension, that is, the elastic member A253 in the balancing machine 25 is in a free state at this time. Since the electric cylinder 24 is not supported by any auxiliary equipment after being subjected to tension, the maximum tension required by the electric cylinder 24 is when the antenna support 21 rotates to the maximum angle β0. When selecting the electric cylinder 24 and arranging the hinge points, it is necessary to ensure that the tension borne by the electric cylinder 24 meets the requirements.

[0062] The lifting device 3 includes a support base 31, a rotating machine 32, a telescopic bracket 33 and an antenna 34. The support base 31 is connected to the support frame 112 on the turntable 11, the rotating machine 32 is connected to the support base 31, the bottom of the telescopic bracket 33 is connected to the support base 31, and the top of the telescopic bracket 33 is connected to the antenna 34. The lifting device 3 is arranged on the right side of the vehicle body and is mounted on the wall.

[0063] A method for using a vehicle-mounted antenna lifting device, comprising the steps of erecting and lowering:

[0064] The erecting step comprises:

[0065] S1: Start the motor A13 to drive the turntable bearing 12 to rotate, and then drive the turntable 11 to rotate to the appropriate direction. Start the motor B23 to drive the electric cylinder 24 to extend, and then drive the horizontal antenna bracket 22 to rotate with the hinge seat C221 as the center.

[0066] S2: When the angle between the antenna support 21 and the turntable 11 is β2, the rotating machine 32 can be started as needed to change the horizontal lifting device 3 to a vertical state, and then the telescopic bracket 33 is extended. The angle β2 is greater than 5 degrees and less than 90 degrees, which is determined by the size of the antenna support 21 and the lifting device 3.

[0067] S3: The motor B23 drives the electric cylinder 24 to continue to extend until the antenna support 21 and the turntable 11 form an angle β0, and the erection step is completed. The angle β0 is greater than or equal to 80 degrees, which is determined by the size of the antenna support 21.

[0068] When the erecting mechanism 2 is lifted to a certain angle, the support seat 26 extends to the highest position. At this time, the support seat 26 no longer provides an upward thrust. During the lifting process, as the angle θ gradually increases, the thrust required by the electric cylinder 24 gradually decreases to zero and turns into a pulling force. When the thrust of the electric cylinder 24 is 0, the angle between the antenna support 21 and the turntable 11 is set to be β1, and the angle β1 is greater than the angle β2 and less than the angle β0. The elastic member A253 is in a free state and no longer provides thrust. When the electric cylinder 24 turns into a pulling force, the elastic member A253 disengages from the pressure rod 254 and no longer provides any pressure until the antenna support 21 rotates to the required maximum angle β0.

[0069] The fallback step includes:

[0070] S1: Start the motor B23 to drive the electric cylinder 24 until the angle between the antenna support 21 and the turntable 11 is greater than the angle β2, then retract the telescopic bracket 33, and start the rotating machine 32 to turn the lifting device 3 into a horizontal state;

[0071] S2: Start the motor B23 to drive the electric cylinder 24 to retract until the antenna bracket 22 is horizontal and in contact with the support seat 26, and start the motor A13 to drive the turntable bearing 12 to rotate, thereby driving the turntable 11 to rotate to a suitable direction.

[0072] When the erecting mechanism 2 falls back, the electric cylinder 24 is in a retracted state, and the pulling force of the electric cylinder 24 gradually decreases. At the angle β1, the pulling force becomes 0 and turns into thrust. At this time, the elastic part A253 in the balancing machine 25 begins to be compressed under the action of the pressure rod 254 to provide auxiliary thrust. When the antenna bracket 21 contacts the support seat 26, the elastic part B263 inside the support seat 26 begins to compress and provide thrust for the antenna support 21 until the bottom of the sleeve D262 contacts the bottom of the sleeve C261, and the sleeve D262 no longer moves downward. At this time, the antenna bracket 21 is in a horizontal state.
