Description

The invention relates to a commercially available hub dynamo with a claw pole generator, permanent magnets, an impeller and stator winding, installed in rollers on wheeled suitcases, pieces of furniture, shopping trolleys, scooters, skateboards, inline skates, shopping trolleys, prams, wheelchairs, walkers, lifting and wheelbarrows, apparatus castors, furniture castors, chair castors and transport rollers. With the help of the hub dynamo integrated in the roller, electricity is generated that can be stored in commercially available accumulators.

This is a hub dynamo, as it reflects the current state of the art in current use in bicycles, which works like a dynamo and generates electricity that can be stored in batteries or comparable devices for further use.

Commercial hub dynamos weigh between 400 and 500 g and are mainly installed in the front wheels of standard bicycles. The rotational energy of the wheel generates alternating current which is used to supply the front and rear lights on the bike with energy. Roller and wheel systems are mainly used in all types of transport, including for the movement of goods in logistics.

In addition, standard castors with different diameters are installed on everyday objects such as wheeled suitcases, pieces of furniture, shopping trolleys, scooters, skateboards, inline skates, shopping trolleys, prams, wheelchairs, walkers, lifting and wheelbarrows and similar everyday objects. The requirements for the respective rollers with different diameters are relatively the same: the focus is on the smooth running property, followed by the requirement to cope with different load weights.

The steering properties of the castors can differ from one another in the everyday objects mentioned: While the castors of standard wheeled suitcases, shopping trolleys and furniture must be movable in all directions, they are used in shopping trolleys, strollers, inline skates, skateboards, wheelchairs, rollators, lifting and wheelbarrows generally fixed and can only be moved forwards or backwards. The requirements consist in particular of the lowest possible friction and smooth running of the rollers. By using lighter and more efficient components, the weight of the hub dynamos is reduced to 50 to 150 g; the diameter of the hub dynamos is also reduced to 10 to 20 mm. By reducing the size and increasing the efficiency of the individual hub dynamos by means of commercially available neodymium magnets, the hub dynamo is installed as a fixed component in a commercially available role.

The hub with the permanent neodymium magnets on the inside is the outer component and encases the commercially available fixed or swivel castor made of polyamide or solid rubber. According to the current state of the art, depending on the application, a large number of types of different roles in which the hub dynamo is installed are in use.

description

The invention relates to a roller with commercially available diameters in which a commercially available hub dynamo is installed as an integral part. The hub dynamo is integrated into the interior of the roller. The hub dynamo is installed in the roller. The wheel of the hub dynamo is an integral part of a common role, such as in DE 10 2010 008 692 A1 , Fig. 1, No. 33 outlined, installed.

It is a commercially available hub dynamo with a claw pole generator, permanent magnets, an impeller and stator winding, installed in rollers on wheeled suitcases, pieces of furniture, shopping trolleys, scooters, skateboards, inline skates, shopping trolleys, prams, wheelchairs, walkers, lifting and wheelbarrows and other objects, in or on which rollers are installed, according to the preamble of claim 1. The hub dynamo integrated into the roller generates electricity that can be stored in commercially available accumulators.

It is a hub dynamo, as it reflects the current state of the art in current use in bicycles. The electricity generated by the hub dynamo can be stored in accumulators or comparable devices in accordance with the USB 5 V standard for further use.

DE 10 2010 008 692 A1 describes an energy self-sufficient electrified role with which a controllable or adjustable energy generation is possible. DE 10 2010 008 692 A1 refers to castors for apparatus, bed casters, furniture castors, chair castors and transport castors, consisting of a fork housing on which a fork is rotatably mounted via a pivot bearing, to which a load-bearing wheel is attached, the apparatus castor being equipped with a power generation and supply the various functions of a role such as swiveling and driving, driving / releasing and braking / locking, as well as the electrical and informational networking of the role actuators and sensors are possible, according to the main patent electrified roller with energy-efficient interlocking switching mechanism ', patent application no. DE 10 2010 004 597 .

In contrast, the present invention discloses the integration of commercially available hub dynamos primarily in castors on wheeled suitcases, pieces of furniture, shopping trolleys, scooters, skateboards, inline skates, shopping trolleys, prams, wheelchairs, walkers, lifting and wheelbarrows, equipment casters, furniture casters, chair castors and transport castors. The rollers can have a fork housing on which a fork is rotatably mounted via a pivot bearing, on which a load-bearing wheel is attached.

Roller and wheel systems are mainly used as in DE 10 2010 008 692 A1 Described for every type of means of transport required and used for the movement of goods in logistics, in addition for internal applications such as beds, furniture, chairs and in the field of laboratories, practices, value centers, for the mobilization of measuring devices, equipment and tool trolleys or moving equipment .

The requirements for the respective roller and wheel systems are different; In addition to the requirement for smooth running properties, all types of load weights should be mastered. The steering properties should be excellent, the means of transport should be able to be safely positioned on the spot. There are dependencies between driving and panning and also between braking and panning; Locking or locking devices have been introduced in a variety of ways.

In addition, roles are currently used in particular on standard travel suitcases, such as those in DE 000008509303U1 , in DE 202019100219U1 or in US 7,406,989 B1 are described. These are usually one-part or two-part rollers that can be moved in any direction and are connected to one another by an axis.

In the Offenlegungsschrift DE 10 2005 054 771 a battery-free and wireless power generator is disclosed, which is mounted on a wheel and on a support frame of a bicycle or a training device. In contrast, the present invention is a power generator in the form of a hub dynamo mounted in a commercially available reel.

Commercially available hub dynamos that are used in the front wheels of bicycles weigh between 400 g and 500 g. The rotational energy of the wheel of a bicycle generates alternating current during operation, which is used to supply the front and rear lights on the bicycle with energy and to store the current in commercially available accumulators for further use.

In addition, standard castors with different diameters are installed on everyday objects such as wheeled suitcases, pieces of furniture, shopping trolleys, scooters, skateboards, inline skates, shopping trolleys, prams, wheelchairs, walkers, lifting and wheelbarrows and similar everyday objects. The focus is on the smooth running properties, followed by the requirement to cope with different load weights.

The steering properties of the castors can differ from one another in the everyday objects mentioned: While the castors of standard wheeled suitcases, shopping trolleys and furniture must be movable in all directions, they are used in shopping trolleys, strollers, inline skates, skateboards, wheelchairs, rollators, lifting and wheelbarrows generally fixed and can only be moved forwards or backwards. The requirements consist in particular of the lowest possible friction and smooth running of the rollers.

Travelers often move wheeled suitcases over long distances and in this way generate rotational energy in the suitcase rolls. The utility model DE 20 2011 005 668 U1 discloses an external power generator which is mounted on the outside of the suitcase in close proximity to the suitcase roll. The power generator is pressed onto the case roll by a spring-loaded lever mechanism so that the case roll drives the dynamo directly. The electricity produced is conducted through a connection cable into the interior of the case and passed on to the accumulator. For the external power generator in utility model DE 20 2011 005 668 U1 it is a side runner dynamo.

In contrast to this, in the present invention there is a hub dynamo, for example as described in the patents EP 1 506 915 A3 , DE 11 2014 004 610 T5 , DE 11 2014 004 610 B4 , DE 11 2014 004 398 T5 , DE 10 2013 007 812 A1 , DE 197 12 818 A1 , DE 103 25 697 A1 and utility model G 92 06 709.3 is known, installed in a suitcase roll.

In the patent specification U.S. 5,873,600 describes a mechanism for generating light in in-line skate wheels, which does not, however, consider the integration of a hub dynamo in the wheel.

In the present invention, the hub dynamo absorbs as an integral part of rollers, in particular on commercially available travel suitcases Energy generated by travelers pulling their suitcase and stored in commercially available accumulators for further use. How these accumulators can be integrated into commercially available suitcases is described, for example, in the patent WO 2015/063752 A1 , FIGS. 18 and 19.

The energy generated by the traveled routes of the travelers is to be converted into electricity by means of the hub dynamo integrated in the suitcase roll and stored in commercially available accumulators in order to enable travelers to be able to supply their electronic devices with energy completely independently and independently of any power supply .

According to the invention, this object is achieved with regard to the integration of the hub dynamo in the role by the subject matter of claim 1, with regard to the integration of the roles with the hub dynamo in everyday objects such as wheeled suitcases, pieces of furniture, shopping carts, scooters, skateboards, inline skates, shopping trolleys, strollers, Wheelchairs, rollators, lifting and wheelbarrows by the claims 1.1. and 1.2. solved.

In particular, the object is achieved by reducing the size and increasing the efficiency of the components of a commercially available hub dynamo, the role in which the hub dynamo is integrated has a claw pole generator, permanent magnets, an impeller and a stator winding, as well as contacts for diverting the alternating current and storing the alternating current in commercially available accumulators. The roller has a running surface and is mounted on the underside of the wheeled suitcase, the piece of furniture, shopping trolleys, scooters, skateboards, inline skates, shopping trolleys, strollers, wheelchairs, walkers, lifting and wheelbarrows.

The advantage of hub dynamos, which have replaced side-rotor dynamos in standard bicycles since the nineties, is their high level of suitability for everyday use due to the weather-independent functionality and higher efficiency.

Commercially available hub dynamos in bicycles are sold by a number of manufacturers; There are generally two basic types of generator; With gearless hub dynamos, permanent magnets located in the hub housing generate a rotating magnetic field through the rotation of the wheel, which induces an electrical voltage in the stator winding (s) installed in the stationary part of the hub; The lights on the bike are then switched on via a switch or an electronic control system. These dynamos have the highest degree of efficiency in operation, but have a low torque loss when switched off due to the magnetic reversal losses that occur even when the dynamo is idling - without a closed lighting circuit.

This design is now almost exclusively found in new bicycles, as it does not require any maintenance and is very efficient.

The second variant involves hub dynamos that are put into operation via a gearbox that can be disengaged in the hub, which avoids idling losses; furthermore, an additional electrical switch is not required. Since the generator has a higher speed, smaller designs are possible, which is also associated with a lower weight compared to gearless hub dynamos. In contrast, the efficiency is not that high and an automatic switch-on of the lighting in the dark without an external power supply is not possible.

Due to the high degree of efficiency, there is now a larger range of chargers that use the electrical energy of the hub dynamo to recharge batteries, cell phones, GPS devices and other commercially available devices via the hub dynamo.

sowie die mechanische und elektrische Leistung;

• • Axle diameter

as well as mechanical and electrical performance;
Compared to pure hubs, hub dynamos are more difficult to run due to their construction, even without the decrease in electrical power. When turning the axle in the hub dynamo or the mounted wheel in the raised wheel fork (only for bicycles), a detent can be felt by hand.

This locking is due to the fact that the poles of the permanent magnets and the pole shoes of the coil are alternately facing each other - here there is attraction - and then again on a gap - here repulsion acts; mechanically, when the wheel is running freely, the individual coils are often perceptible as a slight latching.

Most bicycle dynamos generate an electrical output of up to 3 watts and are designed for lighting systems with a nominal voltage of 6 volts. In Germany, these nominal values for hub dynamos with 3 W / 6 V are specified in the Road Traffic Licensing Regulations (StVZO). A comparable performance should also be generated through the use of hub dynamos in rollers.

• - Verwendung von Neodym-Magneten als Permanentmagneten
• - Verkleinerung des Laufrades auf 50 - 300 mm Durchmesser
• - Reduktion des Durchmessers für die Statorwicklung auf 50 - 300 mm

wird der Nabendynamo verkleinert und somit passfähig für die Abstände in einer Rolle. Das Gewicht wird durch den Einsatz von leichteren und effizienteren Bauteilen auf 100 bis 250 g reduziert; ebenso wird der Durchmesser der Nabendynamos auf 50 bis 300 mm reduziert.By reducing the size and increasing the efficiency of the components, in particular -

• - Reduction of the claw pole generator to 50 - 300 mm in diameter
• - Use of neodymium magnets as permanent magnets
• - Reduction of the impeller to 50 - 300 mm diameter
• - Reduction of the diameter for the stator winding to 50 - 300 mm

the hub dynamo is made smaller and therefore suitable for the distances in a roll. The weight is reduced to 100 to 250 g through the use of lighter and more efficient components; the diameter of the hub dynamos is also reduced to 50 to 300 mm.

With this diameter, the hub dynamo is then integrated in standard luggage and case replacement rolls with an outside diameter of 30-60 mm, an inside diameter of 2-12 mm, a width of 10 of 25 mm and axles between 15-55 mm . The hub with the permanent neodymium magnets on the inside is the outer component and encases standard fixed or swivel castors made of polyamide or solid rubber. According to the prior art, depending on the application, a large number of types of different roles with different energy generation and supply devices are provided for the integration of the hub dynamo.

2. Executive summary

2.1. Technical problem of the invention

There are numerous patents for dynamos on bicycles; According to the state of the art, bicycle dynamos are used to generate rotary or alternating current for the operation of bicycle lamps through the rotary movement of the tires, but now also for storage in commercially available accumulators and the operation of commercially available mobile terminals. Roller, cylinder and hub dynamos have also been known so far as bicycle dynamos.

In contrast to a side rotor dynamo, a hub dynamo is integrated into the wheel of a bicycle. Hub dynamos that are integrated into standard roles on everyday objects do not yet exist. This means that a considerable part of the energy production is foregone. The rotational energy generated by the movement of rollers on trolleys, furniture, shopping trolleys, Kick scooters, skateboards, inline skates, shopping trolleys, strollers, wheelchairs, walkers, lifting and wheelbarrows, apparatus castors, furniture castors, chair castors and transport castors and other roles that are used in everyday life should be made usable by the present invention.

2.2. Solution of the technical problem

The present technical invention relocates this fixation of the hub dynamo in the interior of commercially available rollers; this is done by reducing the size and increasing the efficiency of the existing components. The dynamo converts the rotational energy of the roller into electricity, which can then be stored in commercially available accumulators. The hub dynamo is permanently installed with the rollers and can have different diameters depending on the roller size; So far, comparable hub dynamos only exist for bicycles.

For this purpose, a hub dynamo with more efficient and smaller components is mounted inside rollers. This hub dynamo is mounted in the roller and rotates inside the roller.

In addition, the hub dynamo has electrical contacts that are used to derive, further process and store the electricity generated in commercially available accumulators. The permanent magnets of the hub dynamo rotate in the roller around a claw pole stator and generate a rotating magnetic field through the rotation of the impeller, which induces an electrical alternating voltage in the stationary stator winding. The electrical energy generated by the hub dynamo in the roller can be stored in commercially available accumulators

2.3. field of use

The hub dynamo is to be installed in rolls on everyday objects such as suitcases, furniture, prams, scooters, skateboards, inline skates and other objects with wheels and used to generate energy for everyday objects such as smartphones.

Due to the everyday use of suitcases, prams, shopping carts and other everyday objects on castors, equipping the castors with a hub dynamo can make a significant contribution to the generation of energy for everyday objects such as smartphones, laptops and other electrical devices. This energy can then be stored in lithium batteries, for example, and used further.

The three-phase current, which is generated by the rotating movement of the rollers, is to be used to solve the problem of mobile energy and to be able to supply everyday electronic items with electricity when traveling.

The hub dynamo can be used on castors for suitcases, furniture, strollers, scooters, skateboards, inline skates and other objects as an additional source of energy and generation for private individuals in numerous life situations.

As a traveler, you no longer have to rely solely on electrical sockets or power banks to charge mobile devices; Athletes who are out and about with the hub dynamos in the roles of their sports equipment such as skateboards or inline skates can supply their mobile devices with additional energy and are more independent of the energy supply for long distances.
