Description

Technical Field

[0001] The present invention relates to the technical field of vehicle antennas, and specifically relates to a combined ultra-short wave high-power center-fed vehicle antenna. Background Art

[0002] An automotive antenna is a device that receives high-frequency radio waves transmitted by a transmitting station and transmits them to a receiver of an automotive radio, a car phone, or a radio navigation device for demodulating the carrier wave. A whip-type vehicle antenna is fixed on the roof of the vehicle. The whip antenna includes a flexible antenna and a rigid antenna. The rigid antenna has better performance in receiving high-frequency signals, can receive signals more stably, has high durability and wind resistance, and usually has a higher gain, which can reduce signal attenuation and make the signal transmit farther and more efficiently. However, during high-speed vehicle driving, the rigid antenna has a large wind resistance and consumes the vehicle's traveling energy; the flexible antenna has a low wind resistance and is suitable for use in high-speed vehicles. The flexible antenna bends under strong wind, which can reduce wind resistance and fuel consumption. However, when receiving high-frequency signals, the performance of the flexible antenna is not as good as that of the rigid antenna. During vehicle driving, the flexible antenna is more likely to swing, resulting in unstable signal reception.

[0003] A rigid antenna is installed on the top of the vehicle to stably receive signals. During normal vehicle driving, the rigid antenna can handle the vibration problem of the vehicle. During high-speed vehicle driving, in order to reduce wind resistance, the rigid antenna automatically changes into a flexible antenna, and the flexible antenna bends with the wind, so that the vehicle wind resistance is reduced. In order to achieve the switching between the hard and soft states of the antenna, the present invention provides a combined ultra-short wave high-power center-fed vehicle antenna.

One end of the isolation shaft is meshed and connected to a gear fixed on the waist shaft through a fixed gear, and the gear on the isolation shaft is separated by meshing with the gear fixed on the worm gear through axial movement.

[0022] The wind-resistant device includes a wind-blocking plate, a T-plate fixed on one side of the wind-blocking plate, and a long-axis gear meshing with a row of teeth on the T-plate for transmission connection. The end of the long-axis gear is inserted into a circular groove on the wind-gathering triangular box. The long-axis gear is also meshing with a row of teeth on the multi-fold plate for transmission connection.

[0023] The supercharger includes a ring plate frame, an outer gear ring supported by an outer ring plate frame, an inner cylinder supported by an inner ring plate frame, a C-shaped column fixed to the inner cylinder, a spring connected between the outer gear ring and the inner cylinder, and an elastic curved column for intercepting one end of the C-shaped column.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. During normal vehicle driving, a row of curved section units form a rigid frame. The curved section units restrain the antenna whip, and the antenna whip will not bend and swing. The vibration and impact on the vehicle have little effect on the rigid antenna, and the rigid antenna can stably receive signals. During high-speed vehicle driving, the rigid frame composed of a row of curved section units disintegrates, the antenna whip loses restraint, and the airflow blows the antenna whip, causing the antenna whip to bend with the wind. In this way, the flexible antenna can reduce the wind resistance during high-speed vehicle driving.

[0028] 2. After the vehicle stops driving at high speed, the long metal curved piece resets and slides to control a row of curved section units to re-form a rigid frame, thereby restraining the antenna whip and making the antenna whip become rigid. The rigid and flexible states of the antenna can be automatically switched. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the technical solutions in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1 to 15 , the present invention provides a technical solution: a combined ultra-short wave high-power center-fed vehicle-mounted antenna, including:

[0047] Antenna base 1, which is fixed on the top of the vehicle;

[0048] Antenna whip rod 2, with one end of the antenna whip rod 2 connected to the antenna base 1;

[0049] A row of curved section units 3 arranged on one side of the antenna whip rod 2, and adjacent two curved section units 3 are hinged. When the wind resistance is small, the row of curved section units 3 are fixed at the hinge points to control the antenna whip rod 2 to maintain a rigid state. When the wind resistance is large, the row of curved section units 3 move at the hinge points to make the antenna whip rod 2 become a flexible state;

[0050] A long metal curved sheet 4 passing through the row of curved section units 3, the long metal curved sheet 4 is distributed on one side of the antenna whip rod 2, and the long metal curved sheet 4 adjusts the hinge point state of the row of curved section units 3 by moving;

[0051] A whip head spring assembly 5 connected to one end of the row of curved section units 3, and the whip head spring assembly 5 controls the long metal curved sheet 4 to move and reset by elastically stretching it. Refer to Figure 3 Understand that the whip head spring assembly 5 is a spring assembly in the prior art, applying an upward elastic pulling force to the long metal curved sheet 4;

[0052] A whip root plate 6 connected to the other end of the row of curved section units 3, and the whip root plate 6 is connected to the antenna base 1;

[0053] The antenna base 1 includes an integrated housing 7 fixedly connected to the whip root plate 6, a wind box device 8 installed in the integrated housing 7, and an L-shaped control plate 9 lapped and driven with the wind box device 8. One end of the long metal curved sheet 4 passes through a slide hole opened on the integrated housing 7 and is fixedly connected to the L-shaped control plate 9. A direction slide is arranged in the integrated housing 7 to slide through a plate hole opened on the L-shaped control plate 9, and the antenna whip rod 2 passes through the wind box device 8.

[0054] Refer to Figure 6 Understand that the curved section unit 3 includes:

[0055] Unit plate 10, which is distributed on one side of the antenna whip rod 2;

[0056] A restraint ring 11 vertically fixed in the middle of the unit plate 10, and the antenna whip rod 2 passes through the restraint ring 11;

[0057] A disconnecting component 12 arranged at one end of the unit plate 10, adjacent two unit plates 10 are hinged, and the disconnecting component 12 is used for the card position of the rotating shaft at the hinge;

[0058] Refer to Figure 7It is understood that the disconnecting component 12 includes a direction auxiliary plate 14 fixed to one side of the end of a unit board 10, a return spring piece 13 fixedly connected to the direction auxiliary plate 14, a clamping frame 15 arranged on the other side of the end of the unit board 10, and a C-shaped spring piece 16 supported between the clamping frame 15 and the unit board 10. A clamping plate is arranged on the clamping frame 15, and the clamping plate passes through a plate hole opened on the unit board 10 and then is inserted into a plate groove opened on the rotating shaft at the hinge. One end of the return spring piece 13 is fixed to another unit board 10. The long metal curved piece 4 slides through the inner hole of a flat cylinder arranged on the unit board 10. A notch is opened on the long metal curved piece 4 on one side of the clamping frame 15, and the clamping frame 15 makes the clamping plate of the clamping frame 15 be drawn out from the rotating shaft at the hinge by inserting into the notch of the long metal curved piece 4. Refer to Figure 8 It is understood that if the long metal curved piece 4 descends and the long metal curved piece 4 no longer intercepts the bottom end of the clamping frame 15, the C-shaped spring piece 16 pushes the clamping frame 15 to move leftward. Then the clamping frame 15 no longer positions the hinge shaft between the two unit boards 10, so that the two unit boards 10 can swing relatively. Refer to this again Figure 7 , if the unit board 10 at the bottom end is fixed and the unit board 10 at the upper end can only swing relatively leftward because of the restriction and interception of the direction auxiliary plate 14 on the right side. After the external wind resistance decreases, the return spring piece 13 pulls back the unit board 10 at the upper end. After the direction of the unit board 10 at the upper end swings and resets, the upper and lower unit boards 10 are again on the same vertical line. This process corresponds to the antenna whip rod 2 bending downwind under the condition of large wind resistance and the antenna whip rod 2 returning to a straight state after the wind resistance becomes smaller. The long metal curved piece 4 slides upward in a reset manner, and the long metal curved piece 4 pushes against the clamping frame 15. The clamping frame 15 leaves from the notch of the long metal curved piece 4, that is Figure 8 the clamping frame 15 in

[0059] Refer to Figure 9 It is understood that the wind box device 8 includes a wind-collecting triangular box 17 fixed in the integrated housing 7, a 18-long wind wheel that rotates by exhausting air in the wind-collecting triangular box 17, a supercharger 19 arranged above the wind-collecting triangular box, a lapping device 20 driven by the supercharger 19, and a multi-control gear set 21 for driving the supercharger 19. A shaft body is arranged at the end of the long wind wheel 18 to extend outside the wind-collecting triangular box 17, and the multi-control gear set 21 and the shaft body of the long wind wheel 18 are in transmission connection. An exhaust hole is opened on the housing on one side of the wind-collecting triangular box 17, and the long wind wheel 18 is distributed on one side of the air hole. The wind box device 8 further includes a wind resistance device 22 arranged in the wind-collecting triangular box 17, and the wind resistance device 22 and the multi-control gear set 21 are in transmission connection.

[0060] Refer to Figure 11It is understood that the multi-control gear set 21 includes a waist-shaped shaft 28 supported by a convex seat provided on the air-gathering triangular box 17, a worm 30 provided at one end of the waist-shaped shaft 28, a partition assembly 29 for transmitting between the worm 30 and the waist-shaped shaft 28, a first shaft 26 provided at the other end of the waist-shaped shaft 28, an inclined shaft 25 for perpendicular transmission with the first shaft 26, and a temporary shaft 24 for transmitting between the first shaft 26 and the waist-shaped shaft 28. The air-gathering triangular box 17 also supports the inclined shaft 25 and the first shaft 26 by providing brackets.

[0061] The multi-control gear set 21 further includes a multi-fold plate 23 and a moving speed-limiting valve 27 installed on the multi-fold plate 23. One end of the multi-fold plate 23 is inserted into the supercharger 19, and the moving speed-limiting valve 27 controls the rapid insertion and slow reset of the multi-fold plate 23. The temporary shaft 24 is movably sleeved in a through hole opened on the multi-fold plate 23. One end of the temporary shaft 24 is in meshing transmission connection with a gear fixed on the first shaft 26 through a fixed gear, and the gear on the temporary shaft 24 establishes meshing transmission with a gear fixed on the waist-shaped shaft 28 through axial movement. Refer to Figure 11 It is understood that the moving speed-limiting valve 27 is a pneumatic valve for restricting movement in the prior art. During the rightward movement of the multi-fold plate 23, the process is rapid, and the gas in the pneumatic valve rapidly leaks out. The multi-fold plate 23 is pushed leftward to reset under the action of a spring, and the process is slow because it takes time for the outside air to supplement the pneumatic valve. Specifically, refer to Figure 10 , the air column rapidly inserts into the cylinder barrel, the valve spring piece swings leftward, and the gas in the pneumatic valve can be rapidly discharged. The process of the air column being withdrawn from the cylinder barrel is slow because air is supplemented into the cylinder barrel through a supplementary air fine hole opened by the valve spring piece. The air column is fixed on the multi-fold plate 23, thereby restricting the moving speed of the multi-fold plate 23.

[0062] The partition assembly 29 includes an adjusting body 33, an L-shaped frame 32 slidably passing through a square hole opened on the adjusting body 33, an isolation shaft 31 movably sleeved in a column hole opened on the L-shaped frame 32, and a buffer spring piece 34 connected between the adjusting body 33 and the L-shaped frame 32. One end of the isolation shaft 31 is in meshing transmission connection with a gear fixed on the waist-shaped shaft 28 through a fixed gear, and the gear on the isolation shaft 31 is separated from meshing with a gear fixed on the worm 30 through axial movement.

[0063] The wind-resistant device 22 includes a wind-blocking plate 36, a T-plate 37 fixed on one side of the wind-blocking plate 36, and a long-axis gear 35 that is meshed and connected to a row of teeth set on the T-plate 37. The end of the long-axis gear 35 is inserted into the circular groove opened on the wind-gathering triangular box 17. The long-axis gear 35 is also meshed and connected to a row of teeth set on the multi-fold plate 23. One end of the multi-fold plate 23 passes through the flat hole opened on the shell of the wind-gathering triangular box 17 and enters the interior of the wind-gathering triangular box 17. The wind-gathering triangular box 17 slides through the square hole opened on the T-plate 37 by setting a square column. A plurality of air holes are opened on the wind-blocking plate 36, and an air intake plate hole is opened on the shell of the wind-gathering triangular box 17 on one side of the wind-blocking plate 36. The outside wind enters the wind-gathering triangular box 17 through the air intake plate hole, and the outside wind blows the wind-blocking plate 36.

[0064] The supercharger 19 includes a ring plate frame 39, an outer ring gear 38 supported by the outer ring gear of the ring plate frame 39, an inner cylinder 41 supported by the inner ring gear of the ring plate frame 39, a C-shaped column 40 fixed on the inner cylinder 41, a spring 42 connected between the outer ring gear 38 and the inner cylinder 41, and an elastic curved column 43 for intercepting one end of the C-shaped column 40. A second baffle is provided on the multi-fold plate 23, and the second baffle slides through the inner hole of the flat cylinder provided on the ring plate frame 39. One end of the second baffle intercepts the C-shaped column 40 by being inserted into the surrounding path of the C-shaped column 40. The worm 30 and the outer ring gear 38 are engaged in transmission connection. The outer edge of the ring plate frame 39 is stuck in the annular groove opened on the inner side wall of the outer ring gear 38, and the inner edge of the ring plate frame 39 is stuck in the annular groove opened on the outer side wall of the C-shaped column 40.

[0065] The connector 20 includes a seat frame 48 fixedly connected to the ring plate frame 39, a pressure plate 45 sliding through a square hole opened on the seat frame 48, a wave-pull spring 46 connected between the pressure plate 45 and the seat frame 48, and an extender ring 44 mounted on the L-shaped control plate 9. The pressure plate 45 is provided with a row of teeth to engage with the fixed gear on the extender ring 44 for transmission connection. A partial section of the extender ring 44 is movably sleeved in the circular hole opened on the seat frame 48. One end of the seat frame 48 is fixed on the wind gathering triangle box 17, and one end of the elastic curved column 43 is fixed on the seat frame 48. One end of the pressure plate 45 is supported on the inner cylinder 41 by providing a semicircular plate. The C-shaped column 40 that moves in a circular motion will push the pressure plate 45 it encounters.

[0066] The connector 20 also includes a lead-out shaft 47, which is movably connected to the two through holes provided on the base frame 48 by the lead-out shaft 47 and the worm 30. The L-shaped frame 32 slides through the ridge hole provided on the base frame 48. One end of the lead-out shaft 47 is connected to a row of teeth provided on the pressure plate 45 through a fixed gear, and the other end of the lead-out shaft 47 is connected to a row of teeth provided on the adjusting body 33 through a fixed gear.

[0067] The vehicle-mounted antenna is installed on the top of the vehicle. During vehicle driving, the blowing air flow at the roof acts on the wind blocking piece 36. The faster the vehicle speed, the stronger the blowing wind. As a result, the wind blocking piece 36 is pushed by the blowing wind and moves a greater distance. When the blowing wind is strong enough, it will automatically trigger a morphological transformation, and the antenna changes from a rigid antenna to a flexible antenna bent by the wind. The specific principle is that the wind blocking piece 36 drives the T plate 37 to move excessively, the long-axis gear 35 rotates to drive the multi-fold plate 23 to move, the temporary shaft 24 moves axially, and the gear on the temporary shaft 24 establishes a transmission between the first shaft 26 and the waist shaft 28. The gear on the isolation shaft 31 establishes a transmission between the waist shaft 28 and the worm 30. The rotation of the worm 30 causes the outer gear ring 38 to rotate. By storing energy and increasing pressure through the spring 42, a strong rotational pressure is provided to the inner cylinder 41. Finally, the C-shaped column 40 breaks through the interception of the elastic curved column 43, and the C-shaped column 40 will rotate. Subsequently, the C-shaped column 40 will push against the pressure-triggering plate 45 encountered. The pressure-triggering plate 45 moves to drive the range-increasing ring 44 to swing. One end of the range-increasing ring 44 presses down on the L-shaped control plate 9, and the L-shaped control plate 9 descends to pull the long metal curved piece 4. In this way, the long metal curved piece 4 on one side of the row of disconnecting components 12 slides down as a whole. As previously mentioned, the sliding of the long metal curved piece 4 will cause all the hinged points to become movable. Originally, a row of curved section units 3 formed a rigid frame to restrain the antenna whip 2. After all the hinged points can move, the curved section unit 3 loses its restriction on the antenna whip 2. The antenna whip 2 is an elastically bendable metal in the prior art. When a strong wind blows towards the antenna whip 2, it directly causes the antenna whip 2 to bend downwind. In this way, the flexible antenna can reduce the wind resistance during vehicle driving.

[0068] Reference Figure 14 , when the pressure-triggering plate 45 rises, it will also drive the lead-out shaft 47, and the rotation of the lead-out shaft 47 drives the adjusting body 33 to move. Figure 12 In [reference], the adjusting body 33 moves to the left, drives the L-shaped frame 32 through the buffer spring piece 34, and then the isolation shaft 31 drives the gear to move to the left. The transmission between the waist shaft 28 and the worm 30 is interrupted, and the worm 30 no longer drives the outer gear ring 38 to rotate. Because the strong wind air flow continuously passes through the wind-gathering triangular box 17 and the long wind wheel 18 continuously rotates, the transmission path is disconnected to avoid continuous rotation of the outer gear ring 38 in the flexible antenna state and trigger a new round of control.

[0069] Returning to the rotation position of the C-shaped column 40, after the C-shaped column 40 pushes against the pressure-triggering plate 45, it continues to rotate and is then intercepted by the second blocking plate of the inserted multi-fold plate 23. The timing of the second blocking plate releasing the C-shaped column 40 depends on the wind resistance pressure being lower than the specified level, that is, when the vehicle is driving at a low speed, the flexible antenna changes back to a rigid antenna. Specifically, the acting force of the air flow on the wind blocking piece 36 is small, the wind blocking piece 36 moves reversely, and after subsequent transmission, the multi-fold plate 23 returns to its original position and moves. The second blocking plate on the multi-fold plate 23 is withdrawn from the path of the C-shaped column 40. The C-shaped column 40 that loses the interception can continue to rotate.
