Description

The present invention relates to a multipurpose electric vehicle.

The (ultra) small electric vehicles that have been used in the past are so small that they are so small that they are uncomfortable to occupy and there is almost no cushioning space right next to the seats. I'm worried, and there is no explosive spread. It is understood that it is ideal as an energy-saving transportation means for individuals, but hesitating to ride it. (Ultra)compact electric vehicles have a narrow tread width between tires, and thus have poor stability and riding comfort. Many of the products on sale have open doors that do not have doors, the weather that can be used is limited, and the weatherability is poor. It is dangerous because the line of sight while driving is low and you cannot see the distance. Further, Japanese Patent Laid-Open No. 2015-167470 (Patent Document 1) describes a robot type automobile.

However, it is difficult to make the shape of a solid monocoque chassis, which is currently the mainstream, large and small, because the strength is greatly impaired. Although the outer plate can be slightly extended to the outside, in order to widen the width of the tread on which the load is applied, it is difficult to change the support arm part itself, which receives the load during traveling, by a great deal of work. It was

JP, 2005-167470, A

It is an object of the present invention to provide a multipurpose electric vehicle by making use of the characteristics of the electric vehicle. In addition, since a heavy battery and a motor are mounted on the vehicle body, if the vehicle height is increased, the vehicle body is light and the stability is impaired, and the vehicle height cannot be increased. Since SMS has a large weight that is related to electricity costs and is light in weight, energy-saving performance surpasses any electric vehicle. Prices, maintenance costs, required electricity bills and parking fees are also low. When placed indoors, no parking lot is required. The SMS is an (ultra)compact electric vehicle, which is ultra-compact, and therefore maximizes the convenience and versatility of being able to park and use even in a narrow space. Hereinafter, the SMS in the present specification means a microminiature multipurpose electric vehicle.

A multi-purpose electric vehicle of the present invention includes a chassis having a keel structure, a secondary battery, and a motor, and a vehicle height changing device that is rotatably connected to the chassis, and is connected to the vehicle height changing device. Including dampers. The multipurpose vehicle may be for a single passenger. Further, the drone module can be fixed to the roof.

According to the present invention, a multipurpose electric vehicle can be provided.

The schematic side view of the electric vehicle of this embodiment. The schematic side view of the electric vehicle of this embodiment. The schematic side view of the electric vehicle of this embodiment. Schematic which shows the structure of the electric vehicle of this embodiment. The figure which shows embodiment which changes a vehicle width in this embodiment. The figure which shows the embodiment for performing the collision avoidance of this embodiment. The figure which showed the parking mode of the multipurpose electric vehicle of this embodiment.

Hereinafter, the present invention will be described with reference to embodiments, but the present invention is not limited to the embodiments described below. FIG. 1 is a schematic side view of a multipurpose electric vehicle 100 according to an embodiment. The multipurpose electric vehicle of FIG. 1 is driven by a secondary battery such as a lithium-ion battery, and uses a motor to rotate wheels to run. In one embodiment, the multipurpose electric vehicle 100 is a small-sized vehicle dedicated to single-seater use, and has a weight of about 300 kg. The vehicle width is about 1 m for a single passenger, and the vehicle length is about 2.2 m. A driver 200 is shown in FIG. 1 to show the size of the multipurpose electric vehicle 100.

The vehicle height changing device 110a, 110b of the multipurpose vehicle 100 is capable of changing its vehicle height by the vehicle height changing device 110a, 110b disposed inside thereof. The vehicle height changing device 110a, 110b has a damper 120a, 120b having a jack function. Are connected, and the vehicle height of the multipurpose electric vehicle 100 is changed in accordance with the rotation of the vehicle height changing devices 110a and 110b.

A motor (not shown), a controller (not shown), a secondary battery (not shown), and the like are arranged in the vehicle height changing devices 110a and 110b to enable the vehicle height to be changed and to be universal. The power of the motor is transmitted to the wheels through joints, enabling low-speed running, company width changes, and other flexible operations. Since SMS is light, it can be driven by a DC brushless motor.

FIG. 2 shows a mode in which the vehicle height changing devices 110a and 110b are driven to change the vehicle height of the multipurpose electric vehicle 100 in the present embodiment. The vehicle height changing devices 110a and 110b are rotated by a plurality of motors, the portions housed inside the body are arranged outside the chassis, and the wheels are supported by dampers 120a and 120b arranged on both sides of the vehicle body. The vehicle height is changing. The vehicle height can be changed between about 1 m and about 2 m according to the lengths of the vehicle height changing devices 110a and 110b and the dampers 120a and 120b. For this reason, the multipurpose electric vehicle 100 has improved obstacle running performance and improved running performance such as a water pool.

Further, in another embodiment, the vehicle height changing devices 110a and 110b are operated in cooperation with each other so that the vehicle can be walked on a bad road or a mountain road with four legs, thereby providing the walkability.

Further, in another embodiment, in the arrangement of the embodiment of FIG. 2, it is possible to use the lower part of the vehicle body as, for example, a living space, use the vehicle body as a roof, and use the space under the vehicle body as a living space. In this case, it is possible to use the secondary battery of the multipurpose electric vehicle 100 as a power source and use the electric device in the space under the vehicle body.

The embodiment of FIG. 3 illustrates a mode in which the drone module 130 is fixed to the multipurpose electric vehicle 100. The drone module 130 has a structure similar to that of a conventional roof-mounted type box, and can accommodate the propellers 130a and 130b therein. As a structure, the keel naturally receives force. Further, the drone module 130 includes a motor for driving the propellers 130a and 130b, a battery, an attitude sensor, and an altitude sensor, and enables the multipurpose electric vehicle 100 to fly under the control of the driver. Although two sets of propellers 130a and 130b are shown in FIG. 3, two propellers are symmetrically arranged on the back side of the drawing, and a total of four propellers generate lift. .. The number of propellers can be appropriately increased to 6, 8, or the like.

Further, in this embodiment, the propellers 130a and 130b are not arranged directly above the roof, but are arranged so as to project laterally from the draw module 130 beyond the side surface of the vehicle body to ensure the flight performance of the drone.

FIG. 4 is a schematic diagram illustrating the functions of the multipurpose electric vehicle 100 of this embodiment. For convenience of explanation, the exterior elements of the body are omitted. In the multipurpose electric vehicle 100, a body 180 is fixed on a chassis 140. One end of a vehicle height changing device 110a is rotatably fixed to the chassis 140, and can be rotationally driven by a motor 160a. Further, a damper 120a is rotatably connected to the other end of the vehicle height changing device 110a, and the vehicle height can be changed by moving the tire in the vertical direction of the paper in conjunction with the rotation of the vehicle height changing device 110a. It is possible.

Further, the secondary battery 150 is arranged on the chassis 140, and the keel structure integrally formed with the chassis 140 is configured in the secondary battery 140 itself or in the center of the vehicle body to ensure rigidity in the front-rear direction. ing. Further, a beam structure is symmetrically extended from the keel structure in the width direction of the vehicle body to secure rigidity in the vehicle width direction centering on the keel structure. A seat 170 is installed on the secondary battery 150 via an appropriate spacer member, and various control switches, accelerators, and brakes arranged on the front panel are provided to the control device 170 connected to the steering mechanism. The operation performed by the driver is input to the multi-purpose electric vehicle 100 to enable traveling, motion control, attitude control, flight control, and the like.

FIG. 5 shows an embodiment in which the vehicle width is changed in the present embodiment. The multipurpose electric vehicle 100 according to the present embodiment can have a wider vehicle width according to needs such as comfortability. In FIG. 5, the multipurpose electric vehicle 100 before the vehicle width is widened and the multipurpose electric vehicle after being widened are shown. 100a is shown.

The keel structure can be made lighter, and the keel can be used as a support structure to increase the outer shell. The keel has arms and legs with a high degree of freedom in the joints that resemble a hip joint through connecting parts that allow the vehicle width to be widened. The joint part resembling a hip joint can not only be movable but can also be fixed in angle. The degree of freedom of the joint is not as great as that of the shoulder joint.

The keel, which can bear a load of 1.5 tons or more, receives the force from the underbody.
Various mechanisms can be considered for the outer shell expansion mechanism, such as linear motor drive,
These include screw pistons, air pistons, motor gears, human-powered pushing, opening, etc. Depending on the mold, a deployment mechanism by human power is also provided as an auxiliary to the deployment mechanism.
In most places, such as rural areas, where the product is used as it is deployed, it may be secured with struts to increase strength.In urban areas where deployment and folding are likely to occur frequently, the deployment mechanism is easier and more durable. It may be a mechanism.

There are usually two sets of connecting parts that can widen the vehicle width, but only one set may be provided, or a hip joint-shaped part may be attached to the keel without being attached. Dedicated light automobile tires are attached to the forearms and lower legs, and various driving modes are conceivable due to the drive mechanism provided on the thick upper arms and thighs, but the rotational force is transmitted through the universal shaft to drive the tires.

For example, in the form shown in FIG. 5, it is also used as a bed for sleeping. SMS can also be accompanied when carrying luggage. Unattended SMS flies back and forth between parties and bases. For urban use, White Mouse Takkyubin (registered trademark) described later can also be made. It is also a good idea to install a hydrogen production system or a fuel cell unit on some units. We also offer SMS that can be transformed into a tent in a camp. With the keel structure, the arms and legs can be optimized in different movements when the shell is enlarged. The monocoque structure is a bulge connected to the suspension. It should be noted that the expansion mechanism shown in the attached drawings is just one example.

As shown in FIG. 7, the SMS changes the position of tires to erect the vehicle body, and suspends the multipurpose electric vehicle 100 from a ceiling member of an underground parking lot or a suspension member installed on a reinforced beam 701, for example. It can be parked at a park or can be moved horizontally at the walking speed of a human. When the multipurpose electric vehicle 100 is suspended and parked, the suspension means corresponding to the keel structure arranged on the vehicle body side is provided, and stable parking can be performed without burdening the vehicle body. It can be loaded into a large vehicle and can travel a long distance with a large amount of users. The control software of the SMS will extend over many generations (blocks). In the early generations, only basic driving with electric vehicles was possible, but as the generations progressed, functions were added and strengthened. The existing software for electric vehicles, autonomous driving, robots, and drones will naturally be used as the lower-level software of SMS control software.

FIG. 6 shows an embodiment for avoiding the collision of the present embodiment. In the multipurpose electric vehicle 100 according to the present embodiment, the entire circumference of the vehicle body is constantly monitored by the rider or AI. Even with the current technology, it can be said that it is safer to let the EV take care of the surroundings.
ECS function, Escape, Collision, System, (collision avoidance system).
If there is a possibility of a collision, first run away, depending on the opponent, it may be caught by the arm or leg, and it has a jumping function to ensure upper safety, jump, and avoid a collision. According to a simulation, when a jump function is to be exerted to make a jump, a gravity of about 4 G to 6 G is applied to the vehicle body, but since it is a short time, it is not a heavy burden. The unique 4-leg independent suspension system of the present application enables this ECS function. Light and quick to move. No collision avoidance is implemented in any conventional vehicle due to structural restrictions. The jump function is the most desirable function that is not used.

High-speed gas is also used to assist the jumping power. If cars do not collide with each other, kinetic energy will not cause major destruction. It is extremely dangerous for another vehicle, which has a weight of 5 times or more, to collide with the SMS, which is characterized by its light weight, at high speed. For landing, an airbag may be deployed to absorb the impact. Ultra-lightweight is the feature of SMS, but it is impossible to secure the safety of the driver only by the safety design of the structure. The jumping function is carried out after the vehicle-mounted AI, which is constantly watching the surroundings, determines that there is no obstacle on the vehicle body when it judges that collision other than jumping is inevitable. It's manga-like, but it might be possible to grab something in the sky temporarily.

Initially, it is difficult to predict the situation at landing due to lack of data, so jump only when there is almost no running. These functions are also used to avoid collision with small animals. Raise your rung-over leg above the animal's height. The space between the outer shell and the cockpit is also used as a buffer space. Side airbags may be deployed.
Since the legs and the outer shell of the SMS can be moved separately, even when the tread width of the legs is narrow, it is possible to urgently deploy only the outer shell to absorb a lateral impact. The front and rear impact is received by the keel. Occupant protection is achieved by combining tires, arms, legs, shells, keels, buffer spaces, cockpits, and seats in multiple layers. Suspension-related structural features are also shock-resistant, which helps protect occupants.

Since the flexibility of various forms is high, it is expected that a great deal of work will be required just by completing the dedicated control software for the basic model of SMS. Since SMS production volume is expected, program production costs can be covered on a head-to-head basis.

Crossing ability, water navigation ability. By installing an expandable buoyant body between the keel and the cockpit, you can float completely in water or run a river with minimal installation pressure.
In the case of water navigation, the hull will be stable if the tires are outriggers. It is possible to drive four or eight vehicles in a single passenger car in size, and one passenger can ride and the other three or seven vehicles can operate automatically, and a group with a minimum distance. You can also drive as.

By adopting the above configuration, it is possible to provide a multi-purpose and multi-functional small electric vehicle. Despite its small size, light weight, good electricity cost and low price, SMS has safety, size and flying ability. In addition, when the width of the vehicle is expanded, the SMS has livability and safety comparable to that of a mini vehicle, but far lower electric power consumption and excellent economic efficiency.

(The following is the opinion of the inventor)
Prices, maintenance costs, required electricity bills and parking fees are also low. When placed indoors, no parking lot is required. The SMS is an (ultra)compact electric vehicle, which is ultra-compact, and therefore maximizes the convenience and versatility of being able to park and use even in a narrow space.

◎Specifications of SMS66 Cruising range 60km, maximum speed 60km/h.
Total length less than 2.2m. Weight less than 300 kg (scheduled value) Maximum vehicle width less than 1.5 m (light vehicle frame) to minimum 80 cm can be changed. The height can be changed from 1m to 3m. The vehicle width is less than 1.3m until the law changes. A typical horse can reach a speed of 60 km/h and reach a maximum speed of 77 km/h.

In an ordinary electric vehicle with a long cruising range, the battery is large and heavy, so the motive to reduce the weight of the vehicle body is weak, but in SMS, the lighter the gain, the larger the gain. Because it is extremely small, it can be mounted on a canister and carried. Basically it is a one-seater, but by using a safety seat, it can safely carry up to two people such as infants. It is possible to reduce the number of mothers' electric bicycle accidents that are currently fatal.
The obese SMS has a wide seat width and is strong.

The meaning of SMS is only when the human body can do something impossible.
The sensor also integrates and uses a biological sensor that has a different sensitive area from humans. Night-vision devices, infrared rays, ultraviolet rays, lasers, riders, eyes that can see radiation and minute distances, nose that can detect various poisonous gases and unique odors like dogs with high sensitivity, driver drunk driving Can't Only automatic operation is possible. It has ultrasonic waves, ears that can hear low frequencies, and a tongue that can detect poisonous substances. It carries out digital integrated processing with an in-vehicle computer and informs the operator. The raw data obtained by one SMS sensor is naturally used in the entire SMS through the link route, though privacy is naturally taken into consideration. Initially, it has public nature, such as disaster prevention, road conditions, and improvement of weather forecast accuracy. Naturally, the entire system delivers important information in response to a request from an individual SMS. In Japan, which has many mountainous areas, a dedicated satellite transponder is used for relaying.

When moving a large number of people or traveling a long distance, various technologies have been developed for autonomous driving, such as combining SMS, platooning, and convoys in which the AIs of the vehicles work together. Due to its small size, it can be parked inside a building or indoors. The inventor is developing an odorless tire with little odor. When standing upright, the hook at the tip of the keel can be hung and fixed safely on the ceiling. A special charging station can be installed in the RG type house. There is an SMS mounting location inside the RG. If you go out on a regular basis using SMS, your life will be convenient.

As an additional function, it can also be a personal evacuation capsule at the time of disaster forecast. It has power and communication equipment, is extremely sturdy, and floats even with a little flood. If you evacuate to the SMS, you can send sound, light, radio waves, etc. to the rescue team if necessary, so it is easy to find the missing person and you do not have to worry about damaging the human body, so boldly use heavy machinery You can search quickly. As for the equipment to be installed, reference is made to that of the ship. It can also be lifted by a large horsepower drone for rescue, or hooked on a keel and pulled.

At the shelter, the private space is provided by SMS and the shared space is provided by RG. Since the SMS has a variable size, it is possible to adjust the number of inmates according to the usable area of the shelter floor. An additional outer shell that serves as the ceiling of a private room may be stacked and provided in stock. It is not possible to run as a bed between the cockpit and the outer shell, but if you extend it by about 1 m, you can provide a private private room. In that case, replace the tires with indoor shoes. It's a tool that I usually use like a private car, so I feel calm. The public space provided by the RG includes a kitchen (kitchen K), a medical office, a toilet (T), a child room, a bathroom (B), and the like. In this way, TKB is provided.

Since the keel has a high degree of freedom in arranging parts, it is easy to attach and detach the battery,
If you replace the charged battery, you do not need to charge the car body. Since the battery weighs about 500g instead of about 5kg, it is easy to remove and install for charging. In SMS, if lightness is utilized as a feature and functions are added, it is possible to fly in the sky, cross rivers, and easily navigate by water.

Detailed Description of the Invention
I will explain from the true center of the car body.
At the center of SMS, there is a keel of almost full length, which is a unique technology. The strength of the chassis and suspension is 1.5 tons or more. Straddling the keel, with a cockpit, between which there is a cushioning function, which makes the rider's ride extremely comfortable. The boarding cockpit has a frame or monocoque structure that is extremely sturdy in all directions and has an SMS inner shell on the outside.
Although less secure, for leisure use, a form like horse riding is also possible.

Since there is an outer shell, the monocoque structure increases the weight by increasing the volume, but the material of the inner shell may be a material such as lightweight bulletproof high-performance fiber (ballistic nylon) or GORE-TEX that allows water vapor to pass through. The driver's seat has a built-in safety seat belt, but the structure is suitable for short-distance driving.

There is also a method of obtaining strength as a structure in which the whole is tilted without a reclining mechanism. Thoroughly protect the occupant's head and spine in the event of a collision or a fall. In the SMS that sits astride, the seating position can be lowered.

The tires can be lightweight, non-puncture airless tires, lightweight and non-puncture. Since the forearms and lower legs are close to the ground, make the structure as thin as possible.
By using the latest CFRP material, it is lightweight and thin, and it can give the flexibility of a leaf spring to the forearm and lower leg. The elbows, the parts below the knees, the forearms, and the lower legs are easily damaged by contact with obstacles, but the SMS does not have an in-wheel motor and many operating parts, and thus is not easily damaged. The brake is a coordinated control of regenerative braking and leg movements, and also has an anti-skid function.

Since all legs have independent driving force that cooperates, even if one leg breaks, you can continue running at low speed continuously. You can also change the tires and lower legs of one leg without holding a jack while holding the vehicle body at three points.

In Japan, shoes are taken off indoors, so SMS can be easily replaced with indoor tires. Steering is performed by coordinating the movement of each joint and the output of each motor. At present, automated technology allows even a unicycle to carry people horizontally. An SMS with four or more wheels has extremely high flexibility and allows stable driving. With this new system, you can make small turns on the spot at low speeds, and pass in narrow spaces. This form has little resistance from water when entering water, is hard to break, and is easy to replace.

By collaborating with individual tires and legs, move them individually to traverse a rocky slope. This is the procedure for "securing 3 points" (supporting 3 points) to climb a steep cliff. However, when climbing a hill, the driver's seat will not be perfectly horizontal, although it will not fall.

Although not shown in the figure, the area around the tires will be equipped with mudguards that will be installed to prevent other inconveniences in urban areas. In one form of SMS, the upper arm and thigh become heavier due to the overall weight distribution while increasing the distance to the ground, so that the SMS has a high ability to traverse terrain with large obstacles. SMS is tall, lightweight and highly stable.
However, when used on paved roads, the car body can also be lowered. A normal four-wheeled vehicle cannot run if the bottom of the vehicle body is on, and the center of gravity is high and unstable. As a major feature, each upper arm and thigh drive mechanism includes a battery, a power conditioner, and a cooling mechanism for them in addition to the motor.

The maximum speed and cruising range are low on SMS. Since the body of the SMS is light, it can be used as a suspension under such a device. Mainly cordless for power supply and control, because there is a battery in the upper arm and thigh, you can drive even if the power of the cordless is interrupted.By making it cordless, you do not have to worry about arranging the power supply cable when deploying or tatami mating .. Fewer cordless transmitters could be possible. Since the transmission distance is short, power transmission is easy and reliable.

Since SMS has a wide operating range of joints such as hip joints, it is preferable that the various cables are thin in terms of durability and handling.
The built-in battery will initially use a semi-solid battery, but plans to switch to an all-solid battery. Compared to conventional lithium batteries, all-solid-state batteries are less demanding on horizontality, are resistant to temperature changes, and have high battery performance, so they can be made even smaller.

As a safety design, it is possible to connect power lines and information lines as auxiliary lines, which are extremely thin and flexible. A heavy drive mechanism for the upper arm and thigh has a built-in motor and battery, but since it is in a low position, traveling is stable. It is stable even when the outer shell is opened. It overcomes the problems of the conventional micro electric vehicles, which have a narrow tread width and a bad riding comfort. The movements of the upper arm, thigh and outer shell may be different in the SMS which can be independently fixed to the keel.

If all the motors and batteries are stored in the main body, the car body becomes larger.
The elbows and knees absorb the impact from the road surface.

Basically, the total number of arms and legs is 4, but since it has a built-in battery of about 2 kW, it is possible to add 6 to 8 and it is cordless, so replacement is easy. A 2kw battery is currently about 120mmx110mmx22mm,
It weighs 500 g.

The SMS system of the present application is likely to be applicable to ordinary passenger cars and even large-sized machines in the future as the equipment advances.
Around the keel, there are multiple batteries and the entire battery group control system. Prepare a battery for the dedicated electric heat pump cooler. The total battery of SMS is 6 or more, and the total battery is about 14 to 18 kw, and these batteries provide optimum power interchange. With this amount of power, it is enough to run an EV mini car. The main battery of the car body is charged first, and the lower leg battery is supplied with electricity.

There is a feature that power is supplied from the vehicle body even when there is a large amount of power, such as a jump, for the purpose of avoiding danger. The weight of the motor does not become extremely heavy even if the output becomes large, but the battery becomes the output equal weight and size, so it cannot fit in the space of the upper arm or thigh. The flight unit, which also has its own battery, can be supplied with power when power is cut off, allowing safe landing. The SMS is a sports car EV of the GW type, which is not a high-speed and high-performance EV.

It is not a 4-wheel independent suspension of the car, but a 4-leg independent drive.
The tread width on the left and right of the keel can be different. The outer shell that develops on the outer periphery can be a robust outer shell in consideration of collision with a pedestrian, or the outer shell can be made of a flexible material that inflates like a balloon, if the regulations allow. When the outer shell is unfolded, the space between the cockpit and the cockpit needs to be kept in mind with regard to weight, balance, fixing method of luggage, etc., but it is also suitable for luggage storage. A problem with (ultra)compact electric vehicles is that there is not enough luggage room. A deployable radiator for heat dissipation can also be installed. An ice cooler may be installed, or a dedicated micro heat pump cooler and heater may be equipped.

There are various methods of covering the gap, such as unfolding the folded cover, attaching a panel from the outside, covering a new outer shell, inflating a balloon, and not covering. Even if it is not covered, you may prepare stirrups and steps to deploy the footrest for getting on and off. In addition, since the width of the gap is about 30 cm, an exaggerated device is unnecessary. It is also a good idea to fold the outer shell and get on and off only on the side where you get off and get on. The change of state is carried out while the vehicle is stopped. In order to save energy when the vehicle is stopped for a long time, the use of electric power in each leg is suppressed as much as possible, and even small protrusions on the lower surface of the body support the vehicle body like rivets on the bottom of the bag.

An extremely lightweight SNS, which must be light above all to fly in the air, is highly preferred for this requirement. The SMS, which has a low speed without pressurization, has a keel structure and can be made lighter than a monocoque. A heavy EV cannot jump up. In order to avoid obstacles and evacuate, the SMS, which features an electric flight unit with a built-in battery and features lightweight, flies a short distance. The electric flight unit weighs less than 80 kg, and the battery unit can be detached from the SMS dedicated mount section by hand, or it can be detached by flying. In the integrated state, you can perform integrated control from the SMS cockpit.

The flight unit is folded and carried by unattended SMS.
The electric flight unit with a built-in battery is also considered as a drone-like shape for carrying heavy objects. If there is only one flight unit in the convoy and the squad, by deploying the guideline (guide line), it is possible to use power efficiently and safely for crossing rivers and climbing slopes. In the event of a disaster, deliver the necessary items to the heliport on the roof of a high-rise building where the elevator stopped. For landing, glide wings may be deployed.
Since a flight unit weighing 75 kg can carry more than 400 kg, it can be used as an aerial light work platform in agriculture and forestry. If production volume increases, price will decrease and performance will increase. As safety equipment, established equipment such as an SMS parachute and a professional ejection seat is also possible. Even after the driver escapes, the in-vehicle AI will try to minimize damage to others in the event of a crash. SMS is a flying vehicle that can fly.

Take off and land vertically, and use wings to fly horizontally like an airplane.
It houses the outer shell and wings for low speed flight that can be deployed between the outer shell and the fuselage.
Due to its light weight, the wing for low speed flight can be a flexible wing for easy storage and deployment.

The length of one wing when deployed is approximately 2-3 m. The flying SMS has a fuselage that also produces lift, and the wingspan is approximately 7 to 8 m. The maximum speed of sports aircraft is 500 km/h. Example BD-5, Micromachine. By using wings, the cruising range is increased by 4 to 5 times, enabling high speed flight. Tilt the propeller pod of the flight unit from horizontal to vertical.

The procedure is to take off vertically, hover at an altitude of 500 m (stop in the air), and deploy the wings. Tilt the pod and make a horizontal flight. Fold your legs in a position that offers less resistance. When flying as a flying car, a person qualified as a pilot should board or operate by radio. When flying in a large formation, the formation units do not have to be fully qualified to operate. Utilize the mechanism of collision avoidance in group flights that has already been established. As a classification, it will be an ultra light plane (ultra-light aircraft), but a new classification will be necessary.

According to the document of the Civil Aviation Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, an ultralight power plane is
An airplane with a simple structure equipped with a landing (water) device and a power unit that allows the operator to fly in a seated position, as defined by the Aeronautical Information Circular (AIC), and that meets the following conditions: Say The categories are control surface control type, weight shift control type and parachute type.

Being single-seat or double-seat.
Self-weight is 180 kg or less for single-seat and 224 kg or less for double-seat (“K” is capitalized according to the original text)
The blade area must be 10m or more.
The speed must be 65km or less.
Maximum horizontal speed of 185 km/h or less.
Ultralight motives are easier to get permission to fly than ordinary planes.

It is possible to fly the aircraft, the pilot, and the place of takeoff and landing if the above permission is obtained in advance, as it is not necessary for a general airplane or the skill certification of the pilot. Please register in advance for the flight routes you use everyday, and use IT when you fly to other places and notify the aviation station in advance.

An unmanned companion SMS can carry 100kg of various luggage and fuel cells.
Just as a smart horse falls down so as not to lay down the person when it falls, the SMS constantly keeps track of the surroundings by the AI, and protects the surrounding people and occupants even if it falls. Unlike horses, a warning sound and a synthetic sound are used to alert people who are at risk of human language, such as "Dangerous, please stay away."
Due to this function, it comes with tires with a high degree of freedom, and four legs are also used for avoiding movement.

Comfortability and safety The outer shell can be enlarged as necessary, and the comfortability and safety are improved.
When traveling, there is almost the width and tread of a light car while riding alone.
In regions with low traffic, it can be used almost as wide as a light vehicle without folding.

The classification of traffic regulations may be similar to that of senior cars with a maximum speed of less than 6 km/h. In this use condition, a lightweight ladder frame may be added for reinforcement. In the expanded form, because it has a sufficient width, it is possible to equip it with a door with a glass window, and the use environment such as getting on and off is similar to that of an automobile. Even when it's raining or cold, you'll be fine.

Initially, the control device will be in the form of a car or motorcycle that is familiar to driving,
For the time being, we are planning to introduce a dedicated control device, because SMS is a tool with a concept that has not existed in the past, and we will develop the best shape for that control device and make it an easy-to-use tool. Make full use of AI, VR, biometric sensors, and autonomous driving technology.
The control system is electronic with quintuple redundancy via the ISB, as the mechanism can be powered entirely by electricity.

There are various types of side mirrors, including mirrorless mirrors.
Except for basic operations such as running, turning, and stopping, the operations are voice recognition operations, and the operation is confirmed on the display or sky switch. JP, 2008-013042, Hands-free microphone and seat belt woven with multi-wiring therefor are also used as microphones.

Since the SMS is a tool for personal use, the recognition accuracy of operations and commands is high. It also helps prevent vehicle theft. In addition, biometrics can be applied to prevent theft with body odor, fingerprints, etc. This is as if the horse did not obey any command other than by its owner. If you take it forcibly, call the police with the latest notification device. Most of the habits of personal use can be ported to the SMS that I purchased additionally. For safety, the pilot should operate the car to run, turn, and stop. The use of game controllers is also a consideration. From another point of view, given the current development situation, autonomous driving is likely to be used considerably.

Although the development of autonomous driving is progressing, in SMS, the operator and the staff of the navigation support center determine the situation that is difficult with AI. The data on the running of each car will be used to improve the AI function, except for the part that is personally specified.
In the SMS of the present application, the front leg is an arm and the rear leg is a leg.
Therefore, basic SMS is upper arm and forearm. It has thighs, lower legs, front wheels, and rear wheels.
There may be many joints. Various shapes, lengths, thicknesses, etc. can be considered.

◎ Difference between SMS and robot legs.
In the case of the mechanical leg of the robot, it also has a suspension function for the underbody, but in the SMS, since it has a cushioning function that affects the ride comfort of the occupant between the keel and the cockpit, the suspension structure of the arm and leg is simplified. it can. The tire also has a very high impact absorption function. Shock cushioning is performed with a three-stage stance: tire, arm and leg suspension, and air suspension under the seat.

In SMS, the movement is mainly driven by the rotation of tires, and therefore the front and rear walking ability like the mechanical leg of a robot is not required. In the current robot walking technology, the speed on the road is faster with tire driving. Without walking ability, the structure will be simpler and less prone to failure.
A battery is installed in the vacant space created by the reduced functions above.
Since the battery is heavy, the weight of each upper arm and thigh becomes heavy.
Since it bends to any height by the height of the ground, the height of the driving seat can be adjusted to the same height as the chair, which makes it easier to get on and off.
Should the seat height be about 50-60 cm for a typical chair? The seat height is your choice, and you can set it low or high while driving.

The transition from the running form to the standing state is performed automatically while paying attention to the safety of the surroundings. It is possible for an occupant to run straight or attend at a walking speed of a person without boarding. In a building, it usually doesn't move more than 10km,
You can also walk in roller skating mode.
Because it uses a keel structure, it is light in weight and allows the car body to stand upright, and its leg structure makes it strong against steps in the room and allows you to use stairs. It also has a dedicated low-speed motor centered on torque, which is also used as a brake. Unlike the engine, the motor can be mounted on the same power shaft via the coupling relatively easily in a stacked manner.

The plurality of motors can generate driving force individually or collectively and also serve as a regenerative brake. When standing upright, the main sensor moves to the head. It is a dashboard structure that prevents luggage from being scattered when running straight. If you find it difficult to use, you should use a light EV such as the MC type.

In the standard specifications, small diameter tires are used, but depending on the application, change to large diameter tires, snow tires, water tires, low pressure tires, airless tires. When replacing tires, do not use jacks, etc. as much as possible.
A snow sled plate is attached under the bottom of the main body, and snow tires attached to four legs allow the vehicle to travel on snow. The large snow contact area makes it difficult for the vehicle body to sink. The vehicle height is automatically maintained at the optimum height for running on snow.
Even if it is hard on the ground due to snow, you can fly if it is fine and short distance.

◎ Individual delivery system of luggage by dedicated automatic operation SMS utilizing white rat's courier service (registered trademark), subway network, underpass side road.
The self-driving SMS for exclusive use of individual delivery of luggage can reduce the cross-sectional area of the vehicle body to an extremely small level, so that it is possible to prepare a dedicated delivery path with less civil engineering work. It can solve many problems caused by delivery trucks, which are one of the causes of urban congestion and air pollution.
A customer with a large amount of luggage can speed up the processing of slips at the company if he/she has his/her own white rat and sends it to a Takkyubin (registered trademark) collection and delivery center. Since the main power is obtained from the dedicated pipeline, the battery capacity can be used for loading luggage. If the dedicated pipeline is installed in a newly built high-rise building, it will be possible to deliver individually to the delivery base for each higher floor. On the other hand, the collection of dust by white rats is a hurdle in terms of hygiene, but we would like to realize it. It becomes a gray mouse.

A (ultra) small electric car that delivers a clone robot of a consumer who looks at the actual thing and makes a purchase to a store and takes it back with the purchased product. With the invention of SMS, various methods can be introduced to purchase daily necessities. The shopping robot and the SMS personal computer are integrated like a human horse.
Computer performance increases due to synergistic effects. For example, the SMS carried by a drone may be picked up by one SMS for an individual to the drone pad. Drones are much faster than land transportation, so you can transport supplies to multiple drone pads. The deficits are terrible, and supermarkets and convenience stores are withdrawing from the online supermarket business one after another. Therefore, we propose a shopping service that combines SMS and a shopping robot. A personal (ultra) small electric vehicle that delivers a clone robot of a consumer who looks at the real thing to shop and takes it back with the purchased product. As for the shopping robot, the consumer may operate the one provided in the store with a personal computer or a smartphone at home. It looks like this.

In a situation where a robot is mounted on a personal SMS and going to a store for shopping, where there is a problem with automatic driving on the way, the customer remotely controls the SMS. If the shop's built-in shopping robot can be used, the customer can remotely operate the robot and select products one by one, such as cheap cucumber even if bent, beef with oil well. The clerk only helps confirm cashless payment and load the customer's SMS. Of course, you can also interact with the shop assistants and customers via robots. If the shopping robot installed in the store is in use, the customer's robot selects the product and pays it at the register. You can reduce the frequency of other people coming to your home, which is a crime prevention.

With Takkyubin (registered trademark), instead of lowering the shipping fee, the customer could go to the local center of the courier service or the mail collection center with a personal SMS. The time when an item ordered by online shopping arrives at the customer's nearest distribution center can be known by IT, and SMS goes to the distribution center. You can also go to a dispensing pharmacy to take prescription drugs after a remote medical examination. Commentary (Because the insurance product is exclusively used like the first cancer insurance. It is a right to a foreign insurance company by attaching it to a concrete device called SMS.) Unmanned like SMS Since financial security is a major barrier to widespread use in the event of an accident during driving, the present invention also invented an insurance product that compensates for the cost of reacquiring luggage and vehicles during unmanned driving. Of course, the idea of guaranteeing expensive valuables is a separate insurance contract, in short, if it is not damage to humans or animals, it can be resolved by compensation. All are new business forms that can be achieved when SMS can connect to almost one individual. Since the width of the vehicle is 80 cm or less, which is comparable to that of a bicycle, the existing road in Japan can coexist with automobiles and the like, maximizing the effective road area. If there is a storage place, it is possible to attach a more functional outer shell and stack it further on the outside. Perhaps you can store 5 to 6 sheets in a stack, and you can enjoy various exteriors and designs. The outer shell can also be fitted with an optical camouflage.

From home parking to space Planets have no atmosphere and gravity. It needs a major modification,
SMS can also be used for planetary exploration. In the initial space flight, the lighter the equipment, the more rocket fuel can be saved, and the electricity-powered SMS can operate without air and can be charged by solar cells. It would be particularly effective on planets with a thin atmosphere where the outer shell could be a large area solar cell.

that's all
