Technical Field

Background

Radar navigation is a type of radio navigation. Radar devices are used for navigation and positioning. The radar transmits a pulse wave from the loading transmitting station to the target reflector, and the receiving device receives a reflected wave of the radio wave. After the amplification detection, the reflected wave is displayed as an image signal on the cathode ray fluorescent screen. The position of the target is determined by measuring the azimuth and distance of the target from the screen using the straightness and isokinetic properties of the radio wave (the propagation velocity of the radio wave is equal to 3 x 10^8 m/s).

Nowadays, with the development of science and technology, radar technology is continuously updated, and the volume of the radar equipment is also continuously reduced along with the research of a high-end setting manufacturing process, so that the phenomenon of improving the scanning and detecting mobility of the mobile radar equipment appears. However, due to the incomplete technical development, the stability is poor and the structure is fragile based on the characteristics of some special manufacturing processes in equipment, so that the equipment is not suitable for the non-smooth pavement environment. Currently, there is a need for a radar vehicle damping wheel suitable for high-end equipment manufacturing to improve its damping effect in non-stationary motion environments. The common damping wheel has poor damping effect and fixed damping. If the damping value is too high, the wheel shock absorption is too rigid, and the shock absorption is not favorable during the transportation process. And the damping is too low, so that the rotating speed of the wheel can be limited, and the running speed of the radar vehicle is influenced.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a radar vehicle damping wheel suitable for manufacturing high-end equipment comprises an axle 1, a coil 2 is fixedly connected to an outer ring of the axle 1, spokes 3 are fixedly connected to an outer ring of the coil 2, a push rod 4 is fixedly connected to a top end of the spokes 3, a damping tube 5 is movably sleeved on an outer ring of the push rod 4, a damping spring 6 is sleeved on an outer ring of the damping tube 5 in a surrounding manner, damping oil 7 is placed inside the damping tube 5, dividing strips 8 are fixedly connected inside the damping tube 5, a rotating ring 9 is movably connected to a bottom surface of the damping tube 5, a groove strip 10 is arranged on an inner ring of the rotating ring 9, a square groove 11 is arranged on a bottom surface of the damping tube 5, a baffle 12 is movably connected to a bottom surface of the damping tube 5, a vertical rod 13 is fixedly connected to a surface of the baffle 12, a deflector rod 14 is fixedly, the side surface of the shift lever 14 is movably connected with an electromagnet 16, the top end of the spoke 3 is fixedly connected with a wheel 17, and two sides of the wheel 17 are rotatably connected with fixed magnets 18.

Wherein: the outer ring of the bottom end of the push rod 4 is tightly attached to the inner wall of the branch strip 8. While the push rod 4 moves along the inner part of the branch strip 8, the damping oil 7 can be effectively pushed to flow in the inner part and the outer part of the branch strip 8 in an alternating mode.

Wherein: the coil 2 and the electromagnet 16 are electrically connected with each other.

Wherein: the push rod 4 is provided with a through hole inside, and two ends are respectively positioned at the inner side and the outer side of the branch strip 8. The through holes can balance the hydraulic pressure of the damping oil 7 at the inner part and the outer part of the sub-strip 8, and the damping oil 7 can effectively flow.

Wherein: the fixed magnets 18 are fixedly connected to the fender surfaces on both sides of the axle 1.

Wherein: eight spokes 3, a push rod 4, a damping tube 5, a damping spring 6, damping oil 7, a dividing bar 8, a rotating ring 9, a return spring 15, a shift lever 14 and an electromagnet 16 are respectively arranged and are uniformly distributed on the surface of the outer ring of the axle 1 by taking the axle 1 as a circle center.

Wherein: six baffles 12 and grooves 10 are structurally arranged in each group of damping tubes 5 and are uniformly distributed with reference to the center of the rotating ring 9.

The working principle is as follows: when the radar vehicle carrying the radar equipment moves, the spokes 3 on the outer ring of the axle 1 drive the wheels 17 to rotate through a series of structures. When meeting uneven road surface or obstacle and receiving vibrations in the radar car motion process, four damping spring 6 can effectual absorption vibrations give the impact that radar equipment brought. When receiving vibrations, wheel 17 will drive push rod 4 at the inside free motion of branch 8, because branch 8 divides damping tube 5 into two parts inside and outside, push rod 4 will promote damping oil 7 of damping tube 5 inside simultaneously and freely flow at the inside and outside part of branch 8, and wherein the through-hole of dividing the top of 8 seting up will switch on damping oil 7 at the inside and outside part of branch 8, guarantees that it forms the circulated route. The damping oil 7 is hindered when passing the baffle 12, the larger the resistance is, the larger the damping is, and the smaller the damping is conversely. Wherein the baffle plate 12 decreases the flow capacity of the damping oil 7 when approaching the axis of the damping tube 5, and increases the flow capacity of the damping oil otherwise.

Compare fig. 3 and fig. 4, clockwise rotation ring 9, connect montant 13 through the 10 grooves of the trough bar that rotatory ring 9 surface was seted up, thereby drive baffle 12 and remove, baffle 12 still receives the limiting displacement of square groove 11 at the removal in-process simultaneously, can realize baffle 12 and gather together relatively when rotating ring 9 rotation after the combination, with this hindrance effect that reaches increase baffle 12 to damping oil 7, this damping pipe 5's whole shock attenuation damping value grow this moment, be applicable to the higher speed of a motor vehicle condition, otherwise, baffle 12 removes to the centre of a circle direction of keeping away from rotatory ring 9, baffle 12 reduces damping oil 7's hindrance effect.

When the wheel 17 rotates, the inner coil 2 is driven to synchronously rotate, at the moment, the coil 2 cuts a magnetic induction line between two poles of the fixed magnet 18 and generates induction current, meanwhile, the electromagnet 16 is connected, the electromagnet 16 generates an induction magnetic field and generates attraction force on the shifting rod 14, at the moment, the reset spring 15 is compressed, and as the shifting rod 14 is fixedly connected with the outer ring of the rotating ring 9, the shifting rod is synchronously driven to rotate clockwise, and at the moment, the damping value is increased; when the rotating speed of the wheel 17 is reduced, the induced current is reduced, the return spring 15 drives the deflector rod 14 and the rotating ring 9 to return, and the damping value is automatically reduced. Therefore, the effect of automatically adjusting the damping according to the movement speed of the radar vehicle is achieved. The fixed magnet 18 is fixedly connected to the fender, and is used to maintain the fixed magnet 18 to rotate relative to the coil 2 at all times.
