Description

ELECTRIC VEHICLE

The invention pertains to an electric vehicle for the transport of a person.

Individual electric transport vehicles, also called scooters, are known, for example, from document US6302230B1 , which discloses a wide range of embodiments of such vehicles.

US6302230B1 discloses several vehicle embodiments comprising a platform, one or more wheels and a handlebar. When using the vehicle, the user stands on the platform and his hands grip the handlebar. The wheel(s) is/are driven by a motorized drive arrangement powered by one or more batteries. It is possible for each wheel to be driven by its own motor. One of the embodiments is shown in Figure 1 of the Drawings Chapter of this patent application.

The problem solved by US6302230B1 is to provide automatic stability (also referred to as "balancing") of the vehicle while moving. Irrespective of the skill of the user, the balance of the vehicle increases as its speed increases. The balance is minimal when the vehicle is stationary. For a satisfactory balance, the vehicle speed must be within an optimal speed range. The solution proposed by US6302230B1 is to equip the vehicle with an electronic monitoring and control circuit that monitors the vehicle's real-time speed and when the difference between the vehicle's maximum possible speed and the actual vehicle speed drops below a certain threshold value, the circuit controls the corresponding increase in motor power, so that the vehicle’s speed increases again until a speed value within the optimal speed range is reached.

In addition, vehicle balance can also be partly ensured by determining the centre of gravity of the vehicle+user assembly by the position adopted by user (e.g., the user may put his body weight more on one of his legs, may shift forward or aft, or may adopt a semi-squatting position). US6302230B1 has the disadvantage that maintaining the vehicle's balance during travel is dependent on the electronic speed monitoring and control circuit. In the event of a fault in this circuit or in the case of a similar vehicle but not provided with such a circuit, the vehicle's balance will depend exclusively on the skill of the user, so that an inexperienced user will not be able to benefit from a safe travel.

The present invention aims to provide for a significant improvement in the balance of an electric vehicle intended for individual transport, which is not provided with an electronic speed monitoring and control circuit, and which does not require user experience.

According to the invention, the principle on which the technical solution is based is simple and easy to implement, namely providing an electric vehicle so built that its centre of gravity is positioned as close to the ground as possible and the supporting surface is as large as possible.

The present invention also aims at providing the above-mentioned vehicle with a simple and reliable ski grip/release system for the case in which the user rides the vehicle while wearing skis.

The scope of the invention is achieved by means of an electric vehicle comprising:

- a handlebar having at the top a gripping area configured such that a user can grasp it with one hand or with both hands, and having at the bottom a two-arm fork type intermediate element, each arm being fixed to a first support shaft and to a second support shaft, respectively,

- two supporting surfaces, each supporting surface being connected in a detachable manner either to one of the support shafts respectively, or to one of the arms of the fork type element, respectively

- a first wheel able to rotate around its own axis of rotation, and consisting of a rim provided in its inside with an empty space, and a tire covering the entire outer circumference of the rim,

- a brushless electric motor provided with a motor shaft and a rotor able to rotate around the motor shaft, the motor being powered by two electric batteries and being able to drive the first wheel, - the batteries and the motor are located in the empty space inside the rim so that the motor is arranged between the two batteries, and the motor shaft and the two support shafts have each said axis of rotation as their axis of symmetry (this does not mean that the support shafts rotate together with the motor shaft),

- the batteries and the motor have each said axis of rotation as their axis of symmetry (this does not mean that the batteries rotate together with the motor shaft; this may or may not be the case, depending on the choice of the manufacturer),

- the rotor is fastened to the rim so that any rotation of the rotor around the motor shaft causes a rotation of the rim and, implicitly, of the first wheel,

- the first battery is fastened to one end of the motor shaft and to one end of the first support shaft, and the second battery is fastened to the other end of the motor shaft and to one end of the second support shaft,

- each support shaft is supported by a roller bearing fastened to the rim, respectively,

- each supporting surface is provided with a ski grip/release system.

In an alternative embodiment, the support shafts may not have the same symmetry axis as the motor shaft.

The term "battery" is to be understood in a broad sense, as any item capable of storing electricity, such as, for example, an electric accumulator.

The advantages of the present invention are:

- significant improvement of the balance of an electric vehicle intended for individual transport

- ensuring a more compact vehicle configuration in relation to similar vehicles on the market

- ensuring a customizable vehicle for almost all types of environment

- a simple and reliable ski grip/release system for the case in which the user rides the vehicle while wearing skis.

Figures 2 and 3 illustrate general views and Figure 4 illustrates a section view, corresponding to a first embodiment of an electric vehicle according to the invention, comprising:

- a handlebar 1 having at the top a gripping area 2 configured such that a user can grasp it with one hand or with both hands, and having at the bottom a two-arm 3 A, 3B, fork type intermediate element 3, each arm 3A, 3B being fixed to a first support shaft A1 and to a second support shaft A2, respectively,

- two supporting surfaces S1 and S2, each supporting surface S1 , S2 being connected in a detachable mariner to one of the support shafts A1 , A2, respectively,

- a first wheel R1 able to rotate around its own axis of rotation X, and consisting of a rim 4 provided in its inside with an empty space 5, and a tire 6 covering the entire outer circumference of the rim 4,

- a brushless electric motor M provided with a motor shaft A3 and a rotor R able to rotate around the motor shaft A3, the motor M being powered by two electric batteries B1 and B2 and being able to drive the first wheel R1, - the batteries B1 , B2 and the motor M are located in the empty space 5 inside the rim 4 so that the motor M is arranged between the two batteries B1 , B2, and the motor shaft A3 and the two support shafts A1 , A2 have each said axis of rotation X as their axis of symmetry,

- the batteries B1 , B2 and the motor M have each said axis of rotation X as their axis of symmetry,

- the rotor R is fastened to the rim 4 so that any rotation of the rotor R around the motor shaft A3 causes a rotation of the rim 4 and, implicitly, of the first wheel R1 ,

- the first battery B1 is fastened to one end of the motor shaft A3 and to one end of the first support shaft A1 , and the second battery B2 is fastened to the other end of the motor shaft A3 and to one end of the second support shaft A2,

- each support shaft A1 , A2 is supported by a roller bearing 8 fastened to the rim 4, respectively.

In Figure 4 the rotor R is fixed to the rim 4 by screws, but the fastening can be practically made with any other suitable fastening elements. For example, the fastening of batteries B1 and B2 to the motor shaft A3 and to support shafts A1 , A2 is done by threading.

The motor M and the batteries B1, B2 preferably have an approximately cylindrical shape. Since the batteries B1 , B2 and motor M each have the axis X as symmetry axis, it is understood that the axis X passes through the centres of the approximately circular bases of the batteries B1, B2 and motor M.

Figure 5 shows an exploded view of the motor M and of the batteries B1 , B2 from Figure 4.

The above-mentioned particular layout of the motor M and of the batteries B1 , B2 inside the rim 4 has the effect of significantly improving the vehicle’s balance due to the layout of the centre of gravity of the vehicle inside the wheel R1 , at a relatively small distance in relation to the surface on which the wheel R1 moves.

To further improve vehicle’s balance, the wheel R1 can be advantageously dimensioned; for example, non-limiting values may be a width of 500 mm and a diameter of 300 mm. In general, both the width and the diameter of the wheel R1 may preferably be in the range 250-500 mm, but not limited to this range.

The higher the width of the wheel R1 , the greater the supporting surface of the vehicle on the tread and the stability of the vehicle.

The electric motor M can be controlled by an on/off switching circuit which, in turn, can be controlled by a user by means of a control element. The control element may be, for example, a button placed on the handlebar 1, that can be operated by the user with his fingers. The control element may also be, for example, a smartphone that, by means of a dedicated software application, can remotely operate said on/off switching circuit.

The vehicle according to the invention may be particularly intended for travelling in various climatic conditions or on different surfaces, for example when moving on snow or ice, when the user stands with the skis on the supporting surfaces S1 , S2. For this purpose, each supporting surface S1, S2 may be provided with a first type of ski S grip/release system as shown in Figures 2, 3, 6, 7, 8, 10a, 10b and 14. Said ski grip/release system comprises:

- a lever 10 which, when pressed with the ski sole, causes the tilting of a gripping element 11 articulated to the supporting surface S1, S2, from a first position in which the gripping element 11 is not in contact with the ski S, in a second position in which the gripping element 11 is in contact with the ski S, pressing it on the lever 10 and on the associated supporting surface S1, S2,

- a handle 12 fastened to the gripping element 11 , which when actuated by the user, for example manually or by means of a ski stick, causes the gripping member 11 to be tilted from the second position into the first position

The ski grip/release system may also be of a second type, according to the embodiment of Figures 10c-10h. Said second type is also capable of adjusting the width of the corresponding supporting surface S1 , S2.

Figures 10c and 10d illustrate the second type of ski grip/release system in axonometric and profile view, respectively. Figure 10e is a view of the right side of the system from Figure 10d.

Figures 10f, 10g and 10h are sectional views taken along the planes A-A, B-B and C-C respectively from Figure 10e.

The second type of ski grip/release system comprises a movable piece (also called “blocking element”) Y, two pins b1 , b2 fixed to the movable piece Y and a bolt b3. Each of the pins b1 , b2 and the bolt b3 penetrate into a respective associated hole provided in the body of the supporting surface S1. Bolt b3 passes through the movable piece Y through a through hole. The hole associated with bolt b3 in the body of the supporting surface S1 is threaded inward, as can be seen in Figure 10h. Bolt b3 is provided with a wheel at the end opposite the end that enters the threaded hole. On the bottom of the holes associated with the pins b1 , b2 there is provided a helical spring a which is fixed to one of the ends of the respective pin, as can be seen in Figure 10f. Figure 10g is a section through the corresponding bore that is crossed by the support shaft A1.

The second type of ski grip/release system is capable of adjusting the width of the supporting surface, and functions in the following manner: the spring a is tensioned such that initially the spring elastic force pulls the associated pin b1 , b2, and thus maintains the movable piece Y in contact with the body of the supporting surface S1. Initially, bolt b3 is tightened to the maximum, i.e. the bolt’s wheel comes into contact with the movable piece Y when the latter is in contact with the body of the supporting surface S1. To secure the ski, the user will appropriately unscrew the bolt b3 by means of the wheel at its end, so that when the user manually pulls the movable piece Y and overcomes the elastic force of the spring, the movable piece Y can distance itself from the supporting surface S1 body with a suitable distance.

The user then fixes the ski on the supporting surface S1 , then releases the movable piece Y, which, under the action of the elastic force of the spring, will press on the ski, fixing it. Then the user will properly tighten the bolt b3 so that the movable piece Y will be further pressed on the ski by the bolt b3 tightening force.

In another embodiment of second type of ski grip/release system, the spring a is not fixed to the associated pin b1 , b2, but is only in free contact with it. The spring a is so tensioned that its elastic force pushes the associated pin b1 , b2 and implicitly the movable piece Y. In this case, the bolt b3, by means of the wheel at its end, acts as an arrester for the movable piece Y. The user will perform the same steps described above, only that in the end the pressing force of the movable piece Y on the ski will be determined solely by the tightening force of the bolt b3.

In another embodiment (not shown in the figures), the spring may be located between the bolt b3 wheel and the movable piece Y.

In all variants, the ski fastening force on the supporting surface S1 is adjustable.

Figures 10i and 10 j depict a vehicle according to the invention, provided with the second type of ski grip/release system from figures 10c-10h. In this particular case, the grip/release system is not connected to support shafts A1 and A2, but is connected to the arms 3A, 3B of the fork type element 3 by means of a damper D. The damper D may be any kind of suitable damper, for example it may be a hydraulic or pneumatic damper, as shown in figures 10i and 10j. In this case, by “damper” is to be understood the whole assembly that connects the supporting surface S1 , S2 to the arms 3A, 3B of the fork element 3.

The damper D allows the displacement of the associated supporting surface S1 , S2 on the vertical direction and also allows the front/back tilting of said supporting surface S1 , S2.

Furthermore, the damper D facilitates the vehicle to adjust to bumpy surfaces in the sense of energy consumption reduction. The damper D also facilitates the tackling of more difficult road bumps (in comparison with the situation in which the vehicle is not provided with the bumper D).

In this embodiment, the ski grip/release system is situated above the ski.

However, both first and second types of ski grip/release systems may be situated either below the ski or above the ski.

The advantage of the ski grip/release system being situated above the ski is that only the skis S and the wheel R1 are in contact with the snow, thus reducing friction and energy consumption (in comparison with the situation in which the ski grip/release system is situated below the ski, so the skis S, the wheel R1 and also possibly the ski/release system are in contact with the snow).

Figure 7 illustrates the skis S fastened to the supporting surfaces S1 , S2 by means of the first type of grip/release system. Figure 8 illustrates a user on skis, in the usual position of displacement with the vehicle according to the invention.

When used on snow, when the user stands with the skis on the supporting surfaces S1 , S2, the balance of the user-vehicle assembly is significantly increased due to the fact that the front or rear side of the skis is in contact with and slides on the snow- covered surface.

There are cases, for example, when considering a longer use and/or on a longer distance of the vehicle, that the batteries B1 , B2 inside the wheel R1 are not sufficient, meaning that they discharge before ending the vehicle’s use within parameters (time, distance) originally predicted by the user. To this end, the vehicle according to the invention may be provided with at least one additional battery B3, B4 fastened to the handlebar 1 , outside the first wheel R1 , or other external batterie(s). In this case, the increase of the total reserve of electricity stored in the batteries is done to the detriment of vehicle balancing, because the centre of gravity of the vehicle will move at a greater distance from the tread.

An example of how to mount the additional batteries B3, B4 to the handlebar 1 is exemplified in Figures 9a-9g.

For safe movement with the vehicle according to the invention, the user is required a minimum level of skill that is obtained by exercise. For people who have not yet reached the minimum level of skill (e.g. children, beginners or persons who natively do not have a fully developed sense of balance), the safe movement can take place with a second embodiment of the vehicle according to the invention, as shown in Figures 11 a, 11 b, 12a, 12b. Practically, an additional subassembly is attached to the vehicle of the first embodiment. Said additional subassembly comprises a platform P and an intermediate element 13 integral with the platform P, the intermediate element 13 having one of its ends connected to a second wheel R2 and the other of its ends fixed in a detachable manner to the handlebar 1. The vehicle takes, in this case, substantially the shape of a scooter. The second wheel R2 may be a flywheel or a drive wheel having a construction and a drive mode similar to the first wheel R1.

If the second wheel R2 is a drive wheel, its drive is provided by an additional electric motor arranged inside the second wheel R2. The additional motor and the motor M from the first wheel R1 are powered by the batteries B1 , B2 inside the first wheel R1 and possibly by the batteries B3, B4 from the outside of the first wheel R1 and possibly by some additional batteries (not shown in the figures) attached to the platform P, or by other external batteries (not shown in figures).

The tire of the first wheel R1 and the tire of the second wheel R2 may have physicochemical characteristics (e.g. hardness, friction coefficient, profile shape, etc.) corresponding to the conditions of use of the vehicle. These physicochemical characteristics may be chosen to achieve optimal adherence of the tire to the tread, for example when the temperature is below 0°C and/or the tread is covered with snow and/or ice, or for example under moving conditions on an off-road surface.

The vehicle, according to a third embodiment of the invention, can be used to move on the surface of water. The vehicle according to the third embodiment, shown in Figures 13a and 13b, consists of the vehicle according to the first embodiment which is provided with an additional subassembly consisting of a platform P and an intermediate element 13 integral with the platform P, the intermediate element 13 having one of its ends fastened in a detachable manner to the handlebar 1. The vehicle is further provided with two elongated floating elements 14A, 14B fixed to the intermediate element 13 and located on both sides of the intermediate element 13.

When moving on the water surface, the first wheel R1 is partially submerged in water, and its rotation causes the vehicle to move. Practically, the wheel R1 acts like a paddle.

The wheel R1 is sealed so that there is no possibility of water entering inside the wheel R1 , thus avoiding the failure of the motor M and of the batteries B1 , B2.

The floating elements 14A, 14B are dimensioned so that the platform P and the user standing on the platform P always remain above the water. The vehicle according to the invention can be further provided, as shown in Figure 14, with a transparent element T, of the plate type, having a flat or slightly curved shape, for example fixed to the handlebar or to the fork type element, of width, for example, in the range of 50 cm - 150 cm and height, for example, in the range of 120 cm - 190 cm. For example, the transparent element T is made of plastic and is intended to protect the user of the vehicle like a windshield, during movement, against the wind or against the feeling of wind due to the relative speed between the vehicle and the atmosphere.

The transparent element T is fixed to the handlebar or to the fork type element 3 in a detachable manner.

The transparent element T may be arranged so as to be located between the handlebar 1 and the user, or may be arranged such that the handlebar 1 is located between the transparent member T and the user.

The dimensions of the transparent element are chosen according to the user: for example, for a child, a smaller size (suitable for the height of the child) will be chosen and for an adult, larger sizes (suitable for the adult height) will be chosen.

The vehicle may also comprise an additional surface connected to the transparent element T or forming an integral part of the transparent element T, arranged above the head and shoulders of the vehicle’s user.

Although only the vehicle according to the first embodiment of the invention provided with the transparent element T (and where there is no additional surface above the user) is shown in Figure 14, any of the embodiments of the invention may be provided with the transparent element T and possibly with said additional surface.
