Technical Field

The utility model relates to the field of automobile parts, in particular to a flight warning board capable of being released from an automobile and a flight warning method of the flight warning board.

Background

With the gradual improvement of the living standard of people, automobiles become the most important transportation means in the lives of people, and more people purchase automobiles, however, the frequency of traffic accidents is continuously improved, particularly, the rear-end collision accidents occupy a considerable proportion, and serious casualties and economic losses are caused.

Most rear-end accidents are caused by more and larger traffic accidents caused by direct rear-end collision of the rear vehicle due to incapability of quickly giving warning after the accident or the fault occurs in the front vehicle, or by poor discernability of accident vehicle warning equipment, the rear vehicle has insufficient reaction time and distance to the accident point, and the larger accident is caused. Therefore, traffic authorities specify that when a vehicle is in trouble, a warning device must be used to warn the vehicle behind, the distance between the warning device and the accident vehicle being 100 meters to 250 meters.

The existing warning device is usually a car warning board placed in a trunk for standby, and is usually provided with a light reflecting area, and the warning board is placed at the rear of a car when the car breaks down and used for reminding a following car. If the automobile breaks down during driving, the driver needs to get out of the automobile warning board from the trunk after getting off the automobile, and then walk to a safe distance to place the automobile warning board so as to warn the following automobile. The driver then also withdraws the car warning sign. Because of the inertia of people, people in the field emergency dangerous situation usually cannot place the automobile warning board according to the regulations, even if the automobile warning board is placed according to the regulations, the placement time is long, and the placement speed is slow.

In addition, the driver walks on the road and places the automobile warning board, and in particular, in bad weather such as night, rain, fog, snow and the like, the driver can possibly cause larger traffic accidents.

Thus, the chinese patent application publication No. CN102637394a discloses an utility model named "remote control mobile tripod", which is a warning board for a car, and includes a foldable warning board 10, and the warning board 10 is mounted on a remote control car 17, see fig. 1 and 2. When the movable warning board is not in use, the movable warning board can be folded into the state shown in fig. 1, and the warning board 10 is folded into a square shape.

When the movable warning board is used, the movable warning board is placed on a road surface, the warning board 10 can be unfolded under the control of the remote controller, the remote control vehicle 17 runs forwards under the control of the remote controller, after the remote control vehicle 17 runs to a specified position, the warning board 10 is unfolded into the shape shown in fig. 2 under the control of the remote control, the movable warning board is erected at the rear of a vehicle, and a driver of an incoming vehicle behind the vehicle is warned.

As can be seen from fig. 2, the warning board 10 has a square base board 11, three folding boards 12, 13, 14 are respectively disposed above and on the left and right sides of the base board 11, and the base board 11 and the three folding boards 12, 13, 14 form a triangle with a larger area after being unfolded, so as to form a complete warning board 10. The base plate 11 and the remote control car 17 are supported by the folding arm 15, a motor for driving the folding arm 15 to work is arranged in the remote control car 17, and the motor is controlled by a remote controller to work so as to drive the unfolding and folding of the warning board 10. Two windproof rods 16 are arranged at the front end of the warning board 10, and after the warning board 10 is unfolded, one end of each windproof rod 16 is supported on the ground, so that the warning board 10 is prevented from being blown down due to strong wind.

Such a mobile warning sign is usually placed under a driver's seat or a passenger seat, for example, when the driver uses the mobile warning sign, the driver needs to manually place the mobile warning sign on a road surface, and then use a remote controller to control the running of the remote control car 17 and the unfolding of the warning sign 10. However, if the mobile warning board is placed below the driver's seat or the assistant driver's seat of a bus or a van, the driver needs to get off the bus before placing the mobile warning board on the road surface, so that the driver still needs to walk to the road surface, the driver needs to face dangerous situations, meanwhile, the time for forming effective warning is prolonged, the occurrence probability of secondary accidents is increased, and the use of the mobile warning board is also unfavorable.

In addition, the warning board needs to run on the road surface, and after an accident occurs, fragments and the like of the accident vehicle often appear on the road surface, or a large number of obstacles exist on the road surface, so that the progress of the warning board is influenced, and the warning board is not placed in time or is not placed in place. In addition, if severe environments such as ice on a road surface or a large-area pit exists on the road surface, the warning board cannot be driven to a preset position, and the release of the warning board is also influenced.

Accordingly, chinese patent No. CN201420093446.9 discloses a warning device for vehicles, which has a flying body that can fly vertically to a predetermined height when a traffic accident occurs, and a triangular warning sign is lifted to warn the following vehicles. However, the warning device only displays the warning board above the position of the automobile, and does not meet the requirements of the current traffic regulations: a distance of 100 meters to 250 meters is arranged between the warning device and the accident vehicle. Because the warning device is arranged above the accident vehicle, the distance between the driver of the subsequent vehicle and the accident vehicle is very short when the driver sees the warning sign, and secondary accidents are easy to occur.

Optionally, a cylindrical transceiver 54 is disposed on top of the flight warning board, and the wireless signal transceiver may be disposed in the transceiver 54, and the transceiver may be electrically connected to a controller on the control circuit board, where the controller may receive a signal output by the wireless signal transceiver and may send a signal to the wireless signal transceiver. To determine the location of the flight warning sign, a positioning module, such as a GPS positioning module, may also be provided within transceiver 54 so that a control host or remote control within the accident vehicle may display the location of the flight warning sign. Meanwhile, the control host or the remote controller can be loaded with a fine map, and the control host or the remote controller can send specific GPS positions to the flight warning board, so that the flight warning board can automatically fly to the designated positions. When the flight warning board is recovered, the position of a controller can be judged by sending specific GPS position information needing to be recovered or by detecting the signal intensity of a remote controller, so that the flight warning board can be automatically recovered.

Three support legs 21 are arranged at the bottom of the base 20, and a positioning block 22 is also arranged, wherein the three support legs 21 and the positioning block 22 are uniformly arranged in the circumferential direction of the base 20, so that when the flight warning sign falls to the ground, the flight warning sign can be supported on the ground through the support legs 21 or the positioning block 22. In addition, an image pickup device 23 is arranged outside the peripheral wall of the base 20, and a lens of the image pickup device 23 faces away from the base 20 and is used for shooting images or videos in front of the flight warning sign and transmitting the shot images or videos to a controller on a control circuit board, and the controller can send the images or videos shot by the image pickup device 23 to a control host or a remote controller in an accident vehicle through a wireless signal transmission device. As can be seen from fig. 3, the camera device 23 is located above the positioning block 22.

Preferably, the control host on the vehicle is a control host provided with an advanced driving assistance system ADAS, so that the control host can control the flight warning board to select the optimal landing place.

Of course, the LED lamp strip can flash to emit light or emit light with alternating red and orange-yellow.

In order to control the flying height of the flight warning board, a distance sensor 26 is provided at the lowermost end of the base 20, for example, a boss 27 extending downward is provided at the center of the lower surface of the base 20, the distance sensor 26 is provided on the boss 27, and the distance sensor 26 is directed downward, i.e., the distance sensor 26 is directed toward the road surface when the flight warning board is flying, so that the distance between the flight warning board and the road surface is detected by the distance sensor 26. Preferably, the flight warning board can keep a distance of 4 meters from the road surface, so that the situation that the flight warning board is too high in flight height and touches higher obstacles, such as branches, street lamps, billboards or road signs, is avoided, and the situation that the flight warning board collides with the obstacle on the road surface due to too small distance between the flight warning board and the road surface is also avoided.

In addition, the two sides of the distance sensor 26 are also provided with charging electric shock 29 for charging rechargeable power sources on the flight warning sign, such as lithium batteries.

The warning assembly 50 is disposed on the base 20, as shown in fig. 5 to 7, in this embodiment, the warning assembly 50 includes a telescopic assembly 51, the telescopic assembly 51 includes two tower springs 52 and the wire winding motor 40, and the tower springs 52 are disposed above the base 20, that is, after the flight warning board falls on the road surface, the tower springs 52 are disposed above the base 20, so that the tower springs 52 are not disposed on the same surface of the base 20 as the distance sensor 26.

In the state shown in fig. 3 and 4, the torsion spring 52 is in the housed state, and in the state shown in fig. 5, the torsion spring 52 is in the deployed state. In this embodiment, the lower end of each of the springs 52 is fixed to the base 20, for example, the lower end of the springs 52 is fixed to the peripheral wall of the base 20, and the upper end of the springs 52 is fixed to the transceiver 54. After the expansion of the coil spring 52, the lower end of the coil spring 52 is a larger diameter end, and the upper end of the coil spring 52 is a smaller diameter end, so that the coil spring 52 has a larger diameter near the base 20 and a smaller diameter at an end far from the base 20, and the coil spring 52 gradually decreases in diameter from an end near the base 20 to an end far from the base 20. When the coil springs 52 are deployed, they may be deployed upward along the axis of the base 20, i.e., the transceiver 54 will extend upward along the axis of the base 20.

The warning layer 53 is wrapped outside the tower spring 52, in this embodiment, the warning layer 53 is made of reflective material, and may be reflective cloth, reflective film, reflective plastic sheet, etc., and the warning layer 53 is flexible and may stretch along with stretch of the tower spring 52. In this embodiment, the warning layer 53 is wrapped around the two springs 52, that is, the warning layer 53 is supported by the two springs 52. Of course, in practical application, only one tower spring 52 may be used to support the warning layer 53, or more tower springs 52 may be provided.

In the present embodiment, the number of the springs 52 is two, and the two springs 52 are arranged vertically with each other in the axial line of the base 20, and as can be seen from fig. 7, one spring 52 is located above the other spring 52, and the same coils of the two springs 52 are mutually perpendicular in the axial direction of the base 20, and are arranged with each other between the coils. In this way, the warning layer 53 may be disposed between the two springs 52, and as can be seen in fig. 5, the warning layer 53 will be parallel to the axis of the base 20, which not only reduces wind resistance after deployment of the springs 52, but also ensures that the trailing vehicle can clearly see the flight warning sign.

Preferably, both the inner and outer surfaces of the warning layer 53 are made of reflective materials, and as can be seen from fig. 5, the warning layer 53 does not completely wrap the tower spring 52, and in the spiral warning layer 53, the warning layers 53 of two adjacent turns have gaps so as to reduce wind resistance. Therefore, the inner and outer surfaces of the warning layer 53 are required to be made of reflective materials, so that after the lamp of the coming car behind irradiates the warning layer 53, the reflective materials on the inner and outer surfaces reflect light, and the flight warning board seen by the coming car behind is more close to the cone-shaped cylinder.

When the flight warning board flies to a preset position, after the tower spring 52 is unfolded, the rear vehicle lights irradiate the warning layer 53, and the warning layer 53 made of reflective materials emits bright-eye colors. Preferably, the warning layer 53 is made of reflective material with red-yellow phase, so as to form warning color with red-yellow phase after being irradiated by lamplight. In addition, as the tower spring 52 is cone-shaped, the flight warning board after being unfolded is triangular when the driver of the rear vehicle looks at the rear, and is similar to the existing cone-shaped warning barrel shape, so that the driver of the rear vehicle is facilitated to observe the flight warning board and send warning information in time.

In order to control the expansion and contraction of the tower spring 52, the expansion and contraction assembly 51 is further provided with a wire winding motor 40, as can be seen from fig. 6, the wire winding motor 40 is arranged on one side of the base 20 close to the tower spring 52, a wire winding groove 41 is arranged on one side of the wire winding motor 40, one end of the wire winding 42 is wound on the rotating shaft of the wire winding motor 40 and is positioned in the wire winding groove 41, the other end of the wire winding 42 is fixedly connected with the bottom of the transceiver 54, and thus, the wire winding 42 is driven to expand and contract through the rotating shaft of the wire winding motor 40, the tower spring 52 can be driven to expand and contract, the warning layer 53 is driven to expand and contract, and the flight warning board can change between the storage state and the unfolding state.

The flight warning board is kept in a storage state in an accident vehicle or in the flight process, only after the flight warning board flies to a preset position, the wire collecting motor 40 rotates and releases the storage wire 42, the tower spring 52 expands along with the release of the storage wire 42, so that a conical shape is formed, and warning information is sent to a vehicle coming backward. Preferably, a rear light emitting device, such as a light emitting device emitting a red flashing light beam, is provided on top of the transceiver 54, so that a warning signal can be more effectively emitted to a rear vehicle.

Preferably, a power cord is provided in the receiving wire 42 to power the transceiver 54, so that the light emitting device, the wireless signal transceiver, etc. in the transceiver 54 can be powered through the power cord. Since one end of the storage wire 42 is wound around the motor 40 and the motor 40 is disposed on the base 20, and a power source such as a lithium battery is disposed on the base 20, the storage wire 42 can obtain a stable power source from the lithium battery.

A plurality of light emitting devices are further provided on the springs 52, as shown in fig. 7, the LED lamps 58 are connected to the two springs 52, and the LED lamps 58 may be supplied with power through the springs 52 using the two springs 52 as current carriers. Since the torsion spring 52 is made of a metal material and has its own conductive performance, and the voltage required for the LED lamp 58 is low, typically below 5 v, and the current is also small, the current flowing through the torsion spring 52 is small and does not affect the human body. The current of the coil spring 52 may be supplied by the receiving wire 42 to the transceiver 54, which in turn supplies power to the coil spring 52. The LED lamp 58 is arranged on the tower spring 52, so that a flight warning board can be clearly observed by a driver of a rear vehicle in the flight process or after the flight warning board is unfolded, and the warning effect is better.

The tower spring 52 is prevented from being upwards protruded to influence the flight of the flight warning board in the flight process of the flight warning board, the receiving wire 55 is arranged on the tower spring 52, and as can be seen from fig. 3 and 7, the receiving wire 55 penetrates through the tower spring 52, when the tower spring 52 is in a receiving state, the receiving wire 55 is tied on the tower spring 52 and extends from the transceiver 54 to the edge of the base 20, so that the receiving wire 55 can provide binding force for the tower spring 52 in the flight process of the flight warning board, and the edge of the spring 52 is prevented from being upwards protruded. When the springs 52 are in the expanded state, the storage wire 55 extends along the bus bar direction of the conical springs 52. Preferably, the receiving wire 55 has a certain elasticity to avoid affecting the unwinding of the torsion spring 52 when the torsion spring 52 is unwound.

Referring to fig. 6, four light emitting devices 28 are further disposed on the base 20, and each light emitting device 28 is disposed towards the direction of the tower spring 52, so that when the flight warning board is in the unfolded state, since the light emitting devices 28 are located on the rows of the base 20 and emit light beams upwards, the light beams will reflect light after being irradiated onto the surface of the warning layer 53, which is beneficial for the rear vehicles to observe the flight warning board. Preferably, the light emitting device 28 may be a light emitting device that emits a red light beam or a yellow light beam, such as an LED light emitting device.

The control circuit board of the flight warning board can be further provided with a gravity sensor for detecting the state of the flight warning board, for example, when the flight warning board is in an unfolding state, if the flight warning board falls down due to overlarge wind power, the state of the flight warning board can be detected through the gravity sensor, and therefore the state is timely fed back to a control host or a remote controller of an accident vehicle.

The flight warning sign may be placed on the vehicle, for example, under a trunk or driver's seat of the vehicle, and upon occurrence of a traffic accident, a driver or passenger on the accident vehicle may release the flight warning sign through a control master or remote control provided on the vehicle. Referring to fig. 8 and 9, the control host 60 used with the present embodiment has a base 61, a main body 64 is disposed above the base 61, a display screen frame 63 is fixedly connected with the main body 64, and is supported by the main body 64, and the display screen 62 is disposed in the display screen frame 63.

A through hole is provided in the main body 64, and a life hammer 65 is passed through the through hole and fixed in the through hole to be fixed to the main body 64. In addition, a device 66 for blocking the seat belt is provided on the main body 64, and a USB interface 67 is provided on the main body 64. It can be seen that the control host 60 has various devices for emergency escape, and passengers can escape through the various escape devices on the control host 60 when a traffic accident occurs.

As shown in fig. 10, the control main unit 60 may be disposed in front of the vehicle driving seat, such as in front of the right, and a release button 68 is further disposed in front of the left of the driving seat, so as to implement automatic release of the flight warning sign.

Preferably, in this embodiment, the control host 60 or the remote controller may be connected to a cloud server, and after an accident occurs in the vehicle, the control host 60 or the remote controller may send alarm information to the cloud server, and the cloud server sends alarm information to surrounding vehicles.

Before releasing, the flight warning board is in a storage state, namely a state shown in fig. 3 and 4, so that a driver and passengers can take out the flight warning board from an accident vehicle and place the flight warning board on a road surface, or place the flight warning board above the accident vehicle, or hold the flight warning board by hand, so long as the flight warning board can fly upwards in enough space.

When the driver and the passengers send out wireless control signals to the flight warning board through the control host or the remote controller, the flight warning board executes corresponding operations according to the received signals. For example, when the flight warning board receives an instruction of flying to a preset position, the controller of the flight warning board controls the plurality of ducts 30 on the base 20 to act, namely, controls the motor 32 to rotate and drives the blades 33 to rotate, the flight warning board flies upwards, and the steering, lifting and the like of the flight warning board are realized by controlling the action of the plurality of ducts 30.

In the flight process of the flight warning board, the LED lamp strips on the outer side of the peripheral wall of the base 20 emit light, and the light emitting device on the transceiver 54 can also flash to emit light, so that the rear coming vehicle is reminded of the flight warning board. In addition, the image pickup device 23 on the flight warning sign may capture image or video data on the road surface, and transmit the captured image or video data to the control host or remote controller, which may upload the image or video information to the cloud server. In addition, the driver and the passenger can also know the condition on the road surface in time through the camera device 23, and control the landing place of the flight warning board or control the flight route of the flight warning board.

The distance sensor 26 detects the distance between the flight warning sign and the road surface, and ensures that the distance between the flight warning sign and the road surface is controlled within a predetermined height range. When the flight warning board flies to a preset position, for example, to a position 100 meters behind an accident vehicle, the flight warning board will land on the road surface.

When the flight warning board falls on the road surface, the wire winding motor 40 rotates to drive the storage wires 42 to extend, the two tower springs 52 extend upwards under the action of elastic restoring force, the transceiver 54 will rise upwards, and accordingly the warning layer 53 is driven to extend, and the flight warning board will form a cone with narrow upper part and wide lower part. At this time, the plurality of light emitting devices 28 on the base 20 emit light beams and irradiate the warning layer 53, so that a driver of a rear vehicle can clearly see the conical flight warning board.

When the flight warning board is in the unfolding state, if the wind force on the road surface is large, at the moment, the gravity sensor on the flight warning board detects that the flight warning board is in the shaking state, and the wire collecting motor 40 rotates to drive the collecting wire 42 to shrink by a short distance, so that the height of the tower spring 52 is reduced, and the wind resistance when the flight warning board is not in the flight state is reduced. After the wind force is reduced, the take-up motor 40 will again receive the wire 42 and the flight warning board will resume to the optimal height.

After the accident is processed, the wire collecting motor 40 drives the collecting wire 42 to retract, the tower spring 52 is contracted, the flight warning board is restored to the collecting state, the controller controls the duct 30 to act and drives the flight warning board to fly to the vicinity of the accident vehicle, and drivers and passengers of the accident vehicle can conveniently retract the flight warning board.

In the flight process of the flight warning sign and in the unfolding state, the camera device 23 can continuously shoot images or video signals, on one hand, drivers and passengers of the accident vehicle can watch images behind the accident vehicle through the control host or the remote controller, and on the other hand, the images or videos shot by the camera device 23 can be uploaded to the cloud server, so that the situation of the accident scene can be known in time by rescue workers in the background.

It can be seen that, once a traffic accident occurs, the control host 60 automatically issues a release instruction according to the relevant conditions, and the flight warning board can complete warning fully automatically.

The warning sign can be placed behind the accident vehicle through the flight warning sign fast, and the flight warning sign reaches the position of predetermineeing through the mode of flight, in the abominable or occasion that the road surface has more barriers of environment, the warning sign can be very convenient place, and the time of placement of flight warning sign is very short, can be timely send warning information to the car that comes behind. On the other hand, when the vehicle is overhauled by the side, drivers and passengers can complete full-automatic advanced release without getting off through the release button in the vehicle, the following vehicles are warned at the first time, and the danger caused by manual release is avoided.

In order to automatically release the flight warning sign upon occurrence of a traffic accident, a release device 71 may be provided on the chassis of the vehicle, as shown in fig. 11 to 13, a release device 71 may be provided on the chassis 70 of the vehicle near the rear side, the release device 71 may include a cover 72 and a base 73, the cover 72 may be fixed under the chassis 70 of the vehicle by screws or rivets, etc., the base 73 may be provided under the cover 72, and a cavity may be formed between the cover 72 and the base 73, as shown in fig. 14, in which the flight warning sign 80 may be accommodated.

The telescopic mechanism 74 is fixed in the cover 72, the upper end of the telescopic mechanism 74 is fixed in the cover 72, the base 73 is fixedly connected with the lower end of the telescopic mechanism 74, and a driving motor is further arranged in the cover 72 to drive the telescopic mechanism 74 to stretch and retract, so that the base 73 is lifted and lowered.

When the flight warning board is needed, a driver can press the release button 68 in the vehicle, the driving motor in the cover body 72 drives the telescopic mechanism 74 to stretch, the base 73 descends immediately, the flight warning board 80 placed on the base 73 descends along with the base 73 and is exposed out of the cover body 72, and at the moment, the driver can control the flight warning board 80 to fly to a preset position through the control host 60 and expand the flight warning board to send warning information to a rear coming vehicle.

In addition, the flight warning board 80 does not have to travel to the place through the control host or the remote controller, but can be manually placed on the road surface by a driver, for example, the driver can manually place the flight warning board 80 on the road surface, then release the storage wire 42 through the control motor 40, and the flight warning board is in an extended state, so that the warning effect can be realized.

Of course, the above embodiment is only a preferred embodiment of the present utility model, and may be changed in practice, for example, the telescopic assembly does not necessarily use a tower spring, but may use a scissor mechanism or use a coil spring instead; alternatively, the flight impeller of the flight warning board does not use a duct, but uses other rotor mechanisms and the like, and the purpose of the utility model can be achieved by the change.

Finally, it should be emphasized that the utility model is not limited to the above-described embodiments, but that changes such as changes in the material of construction of the warning layer, changes in the mounting positions of the plurality of sensors, etc. are also intended to be included within the scope of the claims.
