Description

Personal Air Vehicle Having Vacuum Box Type Flight Altitude Lamp

The present invention relates to a flight altitude lamp for a PAV (Personal Air Vehicle), and more particularly, to a personal vehicle equipped with a flight altitude lamp whose external lighting color is changed by reflecting a pressure difference with a vacuum box.

Recently, commercialization of personal air vehicles (hereinafter referred to as PAVs) is in progress.

For example, the PAV has the advantage of being able to move without a runway because it can take off and land vertically using wings, a fuselage, and a propeller as basic components.

Therefore, the PAV is a three-dimensional mobility means in which an airplane is developed as a personal transportation means, so that people or cargo can be transported over the city.

However, although the PAV is a concept of an airplane flying in the sky, it has a PAV lamp with a simple function, and thus acts as a cause of lowering flight safety.

For example, the PAV lamp has a limitation in that it is difficult to estimate the height of the air mobility through the simple blinking and the external exposure lamp shining with the same color illumination.

Furthermore, the PAV lamp makes it difficult for the other party to recognize its altitude position in a dangerous situation that may be encountered between PAVs in the sky, which further exacerbates the lack of external visibility under the same color lighting, thereby signaling that it is more dangerous in a more dangerous situation.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying illustrative drawings, and since these embodiments are examples, those of ordinary skill in the art to which the present invention pertains may be implemented in various different forms. It is not limited to the embodiment.

1 and 2 show the configuration of the vacuum box-type flight altitude lamp 10 applied to the PAV (Personal Air Vehicle) (1).

Referring to FIG. 1 , the PAV 1 includes a flight altitude ramp 10 . In particular, the flight altitude lamp 10 uses a vacuum box device 30 (refer to FIG. 2) of a simple mechanical configuration that moves the color variable device 40 position with a pressure difference according to the height, thereby causing failure and unexpected failures due to atmospheric pressure. While the problem can be minimized, the cost can be significantly reduced compared to electronic equipment.

Accordingly, the PAV 1 implements a feature in which its PAV state is shared with the surroundings accurately through automatic color change according to changes in atmospheric pressure without a separate malfunction.

For example, the PAV 1 includes a fuselage 3 , a wing 5 , a tail wing 7 , a landing gear 8 and a propeller engine 9 . In this case, the fuselage 3 forms a pilot and passenger boarding space, and the wings 5 are provided on the left and right sides of the fuselage 3 as main wings to form a lift-generating airfoil, and the tail The wing 7 is provided at the end of the fuselage 3 to function as a rudder, and the landing gear 8 functions as a vehicle wheel on the road while performing take-off/landing like an airplane, and the propeller engine 9 is the power source of the PAV (1).

Therefore, the fuselage 3 / wing 5 / tail wing 7 / landing gear 8 / propeller engine 9 and the like are common components of recently commercialized personal airplanes, so the PAV 1 is a personal airplane. same as

For example, the flight altitude lamp 10 includes a lamp module 20 , a vacuum box device 30 , a color variable device 40 and a selection switch 50 , and a wing 5 and/or a tail wing 7 . ) provided in the PAV (1) to change the color by the first color pad 41 or the second color pad 43 (see FIG. 2) of the color variable device 40 due to the pressure difference according to the elevation of the PAV 1 ) to inform the surroundings of the flight status.

From this, the lamp module 20 irradiates light forward to the light source unit 25 , and the color variable device 40 uses the light emitted from the light source unit 25 to change the color of the light illuminated to the outside. . In particular, the selection switch 50 moves the aiming device 27 (refer to FIG. 2) of the light source unit 25, and from this, the light source irradiation direction or light amount of the light source unit 25 is adjusted to the driver's preference. It gives the driver the choice of adjusting the brightness and color of the light.

Furthermore, the PAV 1 further includes an emergency warning device 100 , and the emergency warning device 100 includes a sensor 110 , a controller 120 , and an emergency flasher 130 .

For example, the sensor 110 detects an obstacle 200 (refer to FIG. 7 ) approaching the flight area of the PAV 1 , and the controller 120 receives a signal from the sensor 110 to receive the emergency flasher 130 . , and the emergency flasher 130 flashes the light source unit 25 to implement a flashing operation in the flight altitude lamp 10 .

Referring to FIG. 2 , detailed configurations of the lamp module 20 , the vacuum box device 30 , and the color variable device 40 are illustrated.

Specifically, the lamp module 20 includes a lamp lens 21 , a lamp housing 23 , a light source unit 25 , and an aiming device 27 .

For example, the lamp lens 21 is made of a transparent material and irradiates light emitted from the light source unit 25 to the outside. The lamp housing 23 includes a light source unit 25 and a connected power connector, etc. while forming the entire exterior of the lamp module in which the lamp lens 21 is coupled to the front surface. The light source unit 25 is equipped with a bulb or LED that generates light by supplying power, and is assembled to the lamp housing 23 . The aiming device 27 adjusts the light irradiation direction of the light source unit 25 by having an actuator or a motor driven by an electric signal of the selection switch 50 . In this case, the aiming device 27 is a typical component of the lamp module 20 .

In particular, the lamp housing 23 forms a housing inner space 23-1, and the housing inner space 23-1 includes a light source unit 25, a vacuum box device 30, and a color variable device 40. It is built in and provided as a place to be integrated with the lamp module 20 .

Specifically, the vacuum box device 30 includes a vacuum box 31 , a box housing 32 , and a pad moving member 33 .

For example, the vacuum box 31 sets the internal atmospheric pressure to 70-80% of the atmospheric pressure at low ground level as the reference pressure, and sets the contracted state by atmospheric pressure of 760 mmhg at low ground level as the initial height (h). The expansion state due to the action of atmospheric pressure lower than the reference pressure due to the difference in atmospheric pressure is changed to the lighting color change height (H) (refer to FIG. 5). Therefore, the vacuum box 31 is made of a material and structure that contracts and expands due to a difference in atmospheric pressure due to atmospheric pressure. For this, the reference pressure is set to about 600 mmHg.

For example, the box housing 32 surrounds the vacuum box 31 to maintain the shape of the vacuum box 31, and for this purpose, the vacuum box 31 is accommodated and seated in the “U” cross-sectional shape of the upward opening structure. to maintain the shape, and is mounted using parts such as brackets or housings in the inner space 23-1 of the lamp module.

In particular, the box housing 32 provides a place for the pad moving member 33 to be mounted, and for this purpose, a fixed end 32a and a support portion 32b are formed. In this case, the fixed end 32a extends horizontally from the bottom of the box housing 32 to one side to fix the fixed portion 33a of the pad moving member 33, and the support portion 32b is the box housing. By vertically protruding from the side wall of 32 to one side, the pad connecting portion 33c is supported to be bent downward when the pad connecting portion 33c of the pad moving member 33 moves.

In addition, the support part 32b forms a stepped structure so as not to interfere with the movement of the pad connection part 33c of the pad moving member 33 . In addition, the support part 32b forms a height at which the pad connection part 33c of the pad moving member 33 supports the weight of the color variable device 40 at the initial height h of the vacuum box 31 . By doing so, the pad connection part 33c may be inclined downward in the height difference H-h due to the deformation of the vacuum box 31 .

As an example, the pad moving member 33 rises up in conjunction with the expansion of the vacuum box 31 so that the color variable device 40 is brought up close to the light source unit 25 , while the vacuum box 31 contracts. The color variable device 40 is inclined downward so as to move away from the light source unit 25 by going down in conjunction with the light source unit 25 . In this case, it is exemplified that the rising of the color variable device 40 is a low atmospheric pressure situation according to an increase in flight altitude, and the falling is an average atmospheric pressure situation of a low ground clearance.

To this end, the pad moving member 33 is made of an elastic body, and the entire length section is divided into a fixing part 33a, a box contact part 33b, and a pad connection part 33c. In this case, the box contact part (33b) is an intermediate section of the entire length section and forms a contact state with the upper surface of the vacuum box (31) and is linked to the contraction and expansion of the vacuum box (31). The fixing portion 33a extends from one side of the box contact portion 33b in an arc shape to form a rear portion of the entire length section and is fixed to the fixing end 32a of the box housing 32 . The pad connection part 33c extends in a straight line from the other side of the box contact part 33b to form a front section of the entire length section and is supported by the support section 32b of the box housing 32 .

In particular, the pad connection part 33c is inclined at an acute angle to match the height of the support part 32b of the box housing 32 . In addition, the pad connection part 33c has sufficient elasticity to support the weight of the color variable device 40 at the initial height h of the vacuum box 31 .

For example, the color variable device 40 includes a first color pad 41 and a second color pad 42 , and the first color pad 41 and the second color pad 42 are one pad. The entire length section is divided into two halves, and the lower section is divided into the first color pad 41 and the upper section is divided into the second color pad 42 . In this case, the section length of the first color pad 41 may be longer or shorter than the section length of the second color pad 42 , which is set according to the flight altitude of the PAV 1 .

In particular, the first color pad 41 applies a red color to change the light emitted from the light source unit 250 to a red color to generate external illumination, and the second color pad 42 applies blue to the light source unit (The light emitted from 250 is changed to blue color and generated as external illumination. Therefore, the red color of the first color pad 41 is suitable for low altitude, and the second color pad 42 is blue for high altitude. suitable for

Meanwhile, referring to FIG. 3, the vacuum box 31 contracts and expands with an atmospheric pressure difference formed by an atmospheric pressure of 760 mmhg at a low ground clearance and an atmospheric pressure of 600 mmhg or less at a high altitude with an internal atmospheric pressure of 600 mmhg, so that the pad moving member 33 moves and , proves that the movement of the pad moving member 33 can move the positions of the first color pad 41 and the second color pad 42 .

On the other hand, Figures 4 to 8 shows the operating state of the vacuum box-type flight altitude lamp (10).

Referring to the state in which the flight altitude lamp 10 of FIG. 4 is operated at a low altitude, the flight altitude lamp 10 is the first color pad 41 by the light emitted from the light source of the light source unit 25 passing through. 1 A red light, which is the color of the color pad 41, is generated.

The reason for this is that the atmospheric pressure (Pa) is 760mmhg higher than 600mmhg, which is the internal atmospheric pressure of the vacuum box 31, so that the vacuum box 31 is contracted by 760mmhg (that is, the initial state) to its height (h). ), which does not cause movement of the pad moving member 33 , so that the first color pad 41 is positioned downward to face the light source unit 25 while the second color pad 42 is positioned below the light source unit This is because it is located above (25).

In this low altitude condition, the vehicle moves and there is a high probability of colliding with buildings/birds/drones, so there are many dangerous situations. It notifies or warns the opponent that your PAV(1) is at a low altitude.

On the other hand, referring to the state in which the flight altitude lamp 10 of FIG. 5 is operated at a high altitude, the flight altitude lamp 10 is the light from the light source of the light source unit 25 passing through the second color pad 42 . A blue light that is the color of the second color pad 42 is generated.

The reason for this is that at high altitude, the atmospheric pressure (Pb) is less than 600 mmhg, which is lower than 600 mmhg, which is the internal atmospheric pressure of the vacuum box 31, so the vacuum box 31 is in an expanded state (ie, deformed state) due to the internal atmospheric pressure of 600 mmhg. Increasing the height H, which causes the movement of the pad moving member 33, the pad moving member 33 is a box contact part ( By the movement of 33b), the pad connection part 33c is pushed upward.

As a result, the pad connection part 33c of the pad moving member 33 is bent downward with the support part 32b as the center in a state of contact with the support part 32b of the box housing 32, so that the first color pad 41 ) and the second color pad 42 are downgraded to move away from the official unit 25 .

Due to this, the first color pad 41 deviates from the light irradiation path of the light source unit 25 while the second color pad 42 faces the light source unit 25 and is positioned in the light irradiation path.

In this high-altitude condition, it is a safe situation with a low possibility of colliding with vehicles or buildings/birds/drones, so the blue light transmitted through blue is generated as the illumination of the PAV(1), and the PAV Inform the other party that (1) is at a high altitude.

Referring to the operation of the flight altitude lamp 10 of FIG. 6 in the driver selection state using the selection switch 50, it can be seen that the operation of the selection switch 50 is operated at low altitude or high altitude.

As shown, the operation of the selection switch 50 sends an electrical signal to the aiming device 27 of the lamp module 20 to operate the aiming device 27, thereby affecting the pressure difference with respect to the vacuum box 31 Without it, the light source irradiation direction of the lamp module 20 may coincide with the first color pad 41 or the second color pad 42 .

As an example, the operation of the selection switch 50 in the low altitude high is applied to the general red light condition (A), so that the operation of the aiming device 27 changes the light source irradiation direction of the light source unit 25 to the first color pad 41. This causes the red light transmitted through the red color of the first color pad 41 to be illuminated by the PAV 1 , and to the other party that their PAV 1 is at a low altitude with the red illumination. Illustrating that you can notify or warn.

On the other hand, in the operation of the selection switch 50 at high altitude, the switch operation (B) is applied when the blue is changed, so that the operation of the aiming device 27 changes the light source irradiation direction of the light source unit 25 to the second color pad 42 . This causes the blue light transmitted through the blue of the second color pad 42 to be illuminated by the PAV 1, and this blue illumination indicates that the PAV 1 is at a high altitude. inform the other party

On the other hand, referring to the operating state of the flight altitude lamp 10 of FIG. 7 when detecting an obstacle at the flight altitude, the flight altitude lamp 10 is the lighting color of the first color pad 41 or the second color pad 42 . Regardless, the light emitted from the light source unit 25 flickers.

This state is achieved by the operation of the emergency warning device 100 .

For example, the sensor 110 provided in the PAV 1 detects the obstacle 200 within 3 m and transmits it to the controller 120 , and the controller 120 recognizes the obstacle detection signal of the sensor 110 and flickers the light source. generate a signal

Then, the emergency flasher 130 flashes the light source of the light source unit 25 with the light source flashing signal of the controller 120 at a predetermined period so that the flight altitude lamp 10 flashes.

As such, when the obstacle 200 appears within 3 m of its flight area, the PAV 1 warns the obstacle 200 or informs its location by blinking the flight altitude lamp 10 by applying the flashing signal logic. give.

In this case, since the blinking of the flight altitude lamp 10 has a greater atmospheric pressure than the reference pressure at low altitude, the red light of the first color pad 41 informs or warns the other party that its PAV 1 is at a low altitude. On the other hand, since the atmospheric pressure is lower than the reference pressure at high altitude, the blue light of the second color pad 42 informs or warns the other party that its PAV 1 is at a high altitude.

As described above, the vacuum box-type flight altitude lamp 10 applied to the PAV 1 according to this embodiment is located in front of the light source unit 25 that is built in the lamp module 20 to generate light, and the box housing The color variable device 40 is moved and moved by the movement of the pad moving member 33 interlocked with the vacuum box 31 that is accommodated in the 32 and expands due to a change in the atmospheric pressure on the ground that is lowered by the increase in flight altitude compared to the reference pressure. By changing the color of the lighting externally reflected by penetrating the light of the lamp module 20 at the location, the external lighting color change reflecting the pressure difference informs other aircraft drivers of their flight status according to the rise in flight altitude, especially the instrument It has the advantage that the application of an expensive electronic system is not required as the external lighting color change occurs by reflecting the pressure difference with the vacuum box structure of the original configuration.
