Description

Technical Field

[0001] The present invention relates to the technical field of vehicle antennas, and particularly 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 the 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 a better effect when 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 transmission farther and more efficient. However, when the vehicle is traveling at high speed, 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 vehicles traveling at high speed. The flexible antenna bends under strong wind, which can reduce wind resistance and fuel consumption. When receiving high-frequency signals, the flexible antenna has a worse effect than the rigid antenna. During vehicle travel, 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 travel, the rigid antenna can handle the vibration problem of the vehicle. When the vehicle is traveling at high speed, in order to reduce wind resistance, the rigid antenna automatically becomes a flexible antenna, and the flexible antenna bends with the wind, reducing the vehicle's wind resistance. To achieve the switching between the rigid and flexible states of the antenna, the present invention provides a combined ultra-short wave high-power center-fed vehicle antenna.

[0010] The multi-control gear tool also includes a multi-fold plate and a movable speed limiting valve installed on the multi-fold plate. One end of the multi-fold plate is inserted into the supercharger, and the movable speed limiting valve controls the rapid insertion and slow reset of the multi-fold plate.

The vibration and impact on the vehicle have little effect on the hard antenna, and the hard antenna can stably receive signals. During high-speed driving of the vehicle, the rigid frame composed of a row of curved section units is disassembled, the antenna whip loses restraint, and the air flow blows the antenna whip, causing the antenna whip to bend downwind.

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 recombine into a rigid frame, thereby restraining the antenna whip and making the antenna whip become rigid. The hard and soft states of the antenna can be automatically switched. Description of the Drawings

Specific embodiments

[0034] 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. Based on the technical solutions in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] 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: Antenna base 1, and the antenna base 1 is fixed on the top of the vehicle; Antenna whip rod 2, and one end of the antenna whip rod 2 is connected to the antenna base 1; 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 controls the antenna whip rod 2 to maintain a hard state by fixing at the hinge points, and when the wind resistance is large, the row of curved section units 3 makes the antenna whip rod 2 become a soft state by moving at the hinge points; A long metal curved piece 4 passes through a row of curved section units 3. The long metal curved piece 4 is distributed on one side of the antenna whip rod 2, and the long metal curved piece 4 adjusts the articulated point state of the row of curved section units 3 by moving. A whip head spring assembly 5 is connected to one end of the row of curved section units 3. The whip head spring assembly 5 controls the movement and reset of the long metal curved piece 4 by elastically stretching it back. 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 piece 4. A whip root plate 6 is 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. 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 in transmission connection with the wind box device 8. One end of the long metal curved piece 4 passes through a sliding plate hole opened on the integrated housing 7 and is fixedly connected to the L-shaped control plate 9. A direction sliding plate 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.

[0036] Refer to Figure 6 Understand that the curved section unit 3 includes: A unit plate 10, which is distributed on one side of the antenna whip rod 2; 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; A disconnecting component 12 arranged at one end of the unit plate 10. Two adjacent unit plates 10 are articulated, and the disconnecting component 12 is used for positioning the rotating shaft at the articulated part.

[0037] Refer to Figure 7 Understand that the disconnecting component 12 includes a direction secondary plate 14 fixed to one side of the end of a unit plate 10, a return pulling elastic piece 13 fixedly connected to the direction secondary plate 14, a card holder 15 arranged on the other side of the end of the unit plate 10, and a C-shaped elastic piece 16 supported between the card holder 15 and the unit plate 10. A card plate is arranged on the card holder 15, and after passing through a plate hole opened on the unit plate 10, the card plate is inserted into a plate groove opened on the rotating shaft at the articulated part. One end of the return pulling elastic piece 13 is fixed to another unit plate 10. The long metal curved piece 4 slides through an oval hole arranged on the unit plate 10. A notch is opened on the long metal curved piece 4 on one side of the card holder 15, and the card holder 15 makes the card plate of the card holder 15 be pulled out from the rotating shaft at the articulated part by inserting into the notch of the long metal curved piece 4. Refer to Figure 8 Understand that if the long metal curved piece 4 descends, the long metal curved piece 4 no longer intercepts the bottom end of the card holder 15, and the C-shaped elastic piece 16 pushes the card holder 15 to move leftward. Then the card holder 15 no longer positions the articulated shaft between the two unit plates 10, so that the two unit plates 10 can swing relatively. Refer to this again Figure 7If the unit plate 10 at the bottom is fixed, the unit plate 10 at the upper end can only swing relatively to the left, because there is a restriction and interception of the directional sub-plate 14 on the right side. After the external wind resistance is reduced, the return spring 13 pulls back the unit plate 10 at the upper end. After the direction of the unit plate 10 at the upper end is swung back, the upper and lower unit plates 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. After the wind resistance becomes smaller, the antenna whip rod 2 returns to a straight state, and the long metal curved sheet 4 slides upward in a reset manner. The long metal curved sheet 4 pushes the bracket 15, and the bracket 15 leaves the notch of the long metal curved sheet 4, that is, Figure 8 The bracket 15 in the middle is reset and moved to the right, and the bracket 15 is reinserted into the hinge shaft, and the hinge point is locked again, so that the two unit boards 10 adjacent to each other cannot swing relative to each other.

[0038] refer to Figure 9 It is understood that the wind box device 8 includes a wind-gathering triangular box 17 fixed in the integrated housing 7, 18 long wind wheels in the wind-gathering triangular box 17 that rotate by exhausting air, a supercharger 19 arranged above the wind-gathering triangular box 17, a connector 20 driven by the supercharger 19, and a multi-control gear 21 for driving the supercharger 19. A shaft is arranged at the end of the long wind wheel 18 to extend to the outside of the wind-gathering triangular box 17, and a transmission is established between the multi-control gear 21 and the shaft of the long wind wheel 18. An exhaust hole is opened on one side of the shell of the wind-gathering triangular box 17, and the long wind wheels 18 are distributed on one side of the air hole. The wind box device 8 also includes a wind-resistant device 22 arranged in the wind-gathering triangular box 17, and a transmission is established between the wind-resistant device 22 and the multi-control gear 21.

[0039] refer to Figure 11 It is understood that the multi-control gear 21 includes a waist shaft 28 supported by a convex seat set on the wind gathering triangle box 17, a worm 30 set at one end of the waist shaft 28, a partition assembly 29 transmitting between the worm 30 and the waist shaft 28, a first shaft 26 set at the other end of the waist shaft 28, an inclined shaft 25 transmitted perpendicularly to the first shaft 26, and a temporary shaft 24 transmitted between the first shaft 26 and the waist shaft 28. The wind gathering triangle box 17 also supports the inclined shaft 25 and the first shaft 26 by setting a bracket.

[0040] The multi-control gear 21 also includes a multi-fold plate 23, and a movable 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 movable 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 the through hole opened on the multi-fold plate 23. One end of the temporary shaft 24 is meshed and connected with the fixed gear on the first shaft 26 through a fixed gear, and the gear on the temporary shaft 24 is meshed and connected with the fixed gear on the waist shaft 28 through axial movement. Figure 11It is understood that the mobile speed limiting valve 27 is a gas valve that limits movement in the prior art. The multi-fold plate 23 moves right quickly, and the gas in the gas valve leaks out quickly. The multi-fold plate 23 is pushed by the spring to reset to the left, and the process is slow because it takes time for the outside air to replenish the gas valve. Figure 10 The air column is quickly inserted into the cylinder, the valve spring swings to the left, and the gas in the air valve is quickly discharged. The process of extracting the air column from the cylinder is slow because the air is replenished into the cylinder through the air replenishing hole finally opened by the valve spring. The air column is fixed on the multi-fold plate 23, thereby limiting the movement speed of the multi-fold plate 23.

[0041] The partition assembly 29 includes an adjusting body 33, an L-shaped frame 32 that slides through a square hole opened on the adjusting body 33, an isolation shaft 31 that is movably sleeved in a column hole opened on the L-shaped frame 32, and a buffer spring 34 connected between the adjusting body 33 and the L-shaped frame 32. One end of the isolation shaft 31 is meshed and connected to a gear fixed on the waist shaft 28 through a fixed gear, and the gear on the isolation shaft 31 is separated by meshing with the gear fixed on the worm 30 through axial movement.

[0042] The wind-resistant device 22 includes a wind-blocking piece 36, a T-plate 37 fixed on one side of the wind-blocking piece 36, and a long-axis gear 35 meshing and transmission connected with a row of teeth arranged on the T-plate 37. The end of the long-axis gear 35 is inserted into a circular groove provided on the wind-gathering triangular box 17. The long-axis gear 35 is also meshing and transmission connected with a row of teeth arranged on the multi-fold plate 23. One end of the multi-fold plate 23 passes through the flat hole provided 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 provided on the T-plate 37 by providing a square column. A plurality of air holes are provided on the wind-blocking piece 36. An air intake plate hole is provided on the shell of the wind-gathering triangular box 17 on one side of the wind-blocking piece 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 piece 36.

[0043] The supercharger 19 includes a ring plate frame 39, an outer ring gear 38 supported by an outer ring of the ring plate frame 39, an inner cylinder 41 supported by an inner ring 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 is inserted into the circumferential path of the C-shaped column 40 to intercept the C-shaped column 40. The worm 30 and the outer ring gear 38 are meshed and driven. The outer edge of the ring plate frame 39 is inserted into 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 inserted into the annular groove opened on the outer side wall of the C-shaped column 40.

[0044] The lapping device 20 includes a base frame 48 fixedly connected to the ring plate frame 39, a hair-trigger plate 45 slidably passing through a square hole formed in the base frame 48, a wavy tension spring piece 46 connected between the hair-trigger plate 45 and the base frame 48, and an extender ring 44 placed on the L-shaped control plate 9. A row of teeth is provided on the hair-trigger plate 45 to mesh and drive-connect with a fixed gear on the extender ring 44. A partial section of the extender ring 44 is movably sleeved in a round hole formed in the base frame 48. One end of the base frame 48 is fixed to the wind-collecting triangular box 17. One end of the elastic curved column 43 is fixed to the base frame 48. One end of the hair-trigger plate 45 abuts against the inner cylinder 41 by means of a semi-circular plate. The circumferentially moving C-shaped column 40 will push against the encountered hair-trigger plate 45.

[0045] The lapping device 20 further includes a lead-out shaft 47. The lead-out shaft 47 and the worm 30 are respectively movably sleeved in two through holes formed in the base frame 48. The L-shaped frame 32 slidably passes through a ribbed hole formed in the base frame 48. One end of the lead-out shaft 47 meshes and drive-connects with a row of teeth provided on the hair-trigger plate 45 by means of a fixed gear. The other end of the lead-out shaft 47 meshes and drive-connects with a row of teeth provided on the adjusting body 33 by means of a fixed gear.

[0046] The vehicle-mounted antenna is installed on the top of the vehicle. During vehicle travel, the blowing air flow at the roof will act 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 to move 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, 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 external gear ring 38 to rotate, and the internal cylinder 41 is provided with a strong rotational pressure through the spring 42 to store and increase pressure. Finally, the C-shaped column 40 breaks through the interception of the elastic curved column 43, the C-shaped column 40 will rotate, and immediately afterwards, the C-shaped column 40 will push against the encountered hair-trigger plate 45. The hair-trigger plate 45 moves to drive the extender ring 44 to swing. One end of the extender ring 44 presses down the L-shaped control plate 9, and the L-shaped control plate 9 descends to pull the long metal curved piece 4. As a result, the entire long metal curved piece 4 on one side of the row of disconnecting components 12 slides down. As previously mentioned, the sliding of the long metal curved piece 4 will cause all the hinge points to become active states. Originally, a row of curved section units 3 formed a rigid frame to restrain the antenna whip 2. After all the hinge 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 travel.

[0047] Reference Figure 14, when the hair pressing plate 45 rises, it will also drive the lead-out shaft 47, and the rotation of the lead-out shaft 47 drives the adjustment body 33 to translate. Figure 12 The adjustment body 33 in Figure 12 translates to the left, drives the L-shaped frame 32 through the buffer spring piece 34, and further drives the isolation shaft 31 to drive the gear to translate to the left, interrupting the transmission between the waist-shaped shaft 28 and the worm 30. The worm 30 no longer drives the outer gear ring 38 to rotate. Because the strong wind airflow continuously passes through the wind-gathering triangular box 17 and the long wind wheel 18 continuously rotates, the transmission path is disconnected to avoid the continuous rotation of the outer gear ring 38 in the soft antenna state and trigger a new round of control.

[0048] Return to the rotation position of the C-shaped column 40. After the C-shaped column 40 pushes against the hair pressing plate 45, it continues to rotate and is then stopped by the second blocking plate of the multi-folded plate 23 inserted therein. 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 traveling at a low speed and the soft antenna becomes a hard antenna again. Specifically, the acting force of the airflow on the wind blocking piece 36 is small, the wind blocking piece 36 translates in the reverse direction. After subsequent transmission, the multi-folded plate 23 resets and translates, and the second blocking plate on the multi-folded 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, and finally the C-shaped column 40 is intercepted by the elastic curved column 43 again, that is Figure 14 the state, which is the starting state and also the ending state.
