Definitions

  • Bicycle frame in particular for electric bicycles, with a receptacle spanning
  • the invention relates to a two-wheel frame, especially for electric bicycles, with interconnected at nodes, load-bearing frame parts.
  • Such frame parts are in diamond frame or derived from the diamond frame frame shapes, such as those used in bicycles and electric bicycles, for example, the seat tube, the down tube and the top tube. At the nodes, the frame parts are connected by sleeves or welded joints.
  • Electric bicycles have both a pedal drive and an electric motor drive. In recent years, these types of bicycles, which are also referred to as pedelec or e-bike, are very popular, especially among the older consumer group.
  • the support provided by the electric motor drive makes it possible to cope with longer journeys more quickly and master slopes with less effort.
  • the locomotion assisted by the electric motor allows a constant cruising speed even with decreasing physical performance.
  • the electric bicycles are mostly designed for locomotion on the road or the bike path.
  • the electromotive drive requires the entrainment of a power source that powers the motor.
  • the energy source is usually in the form of a rechargeable accumulator.
  • any self-sufficient electrical energy source irrespective of its rechargeability, ie also a battery, is referred to as the accumulator.
  • the size of the accumulator depends on the size and the power of the engine, the distance to be managed with a battery charge and the strength of the support to be provided by the engine.
  • the accumulator is externally mounted on the bicycle or carried by the driver, for example on the luggage rack, in a holder on the frame or in the backpack.
  • An attachment of the accumulator on the luggage rack of a bicycle is known for example from DE 69603397 T2. Since a rechargeable battery has a high weight sits, shifts when mounted on the luggage rack the overall focus of the bike still up. This affects the driving dynamics properties.
  • Another disadvantage of the solution of DE 69603397 T2 can be seen in the outside of the frame mounted wiring, which establishes the connection between the engine and battery. Outside the frame, the wiring is exposed and can be easily damaged in a fall.
  • At least one frame part has at least three at least partially juxtaposed and spaced-apart profile elements, which span a receptacle for bicycle accessories.
  • a rigid receptacle for the bicycle accessories in particular an accumulator, created.
  • the basic geometry of the frame does not change, because the profile elements and the receptacle simply replace the conventional frame part. Due to the spacing of the profile elements from each other, the area moment of inertia increases compared to the previous frame part, so that the profile elements can be made filigree without sacrificing the rigidity.
  • At least part of the profile elements may be connected to one another in pairs by means of stiffening walls extending along their longitudinal direction and enclosing the receptacle at least in sections.
  • the stiffening walls lead to a further stiffening of the profile elements having frame part in the recording. Furthermore, they form a protection of the arranged in the receptacle accumulator or other bicycle accessories.
  • the stiffening walls also make it easier to insert the accumulator or other accessories in the receptacle by serving as a guide.
  • the stiffening walls can span a cross section which opens transversely to the longitudinal direction of the profile elements in a U-shaped manner.
  • the legs of the U-shaped cross-section may surround the receptacle laterally and in particular be formed by the stiffening walls.
  • the leg edges may define a receiving opening for the accumulator or other accessory parts extending in the longitudinal direction of the profile elements and transversely thereto.
  • the bicycle frame may include a flap or cap through which the receptacle or receptacle is closable to secure the accumulator or bicycle accessories in the receptacle.
  • the flap or lid may be connected by load-transmitting fasteners to the receptacle-spanning profile elements to effect further stiffening. A part of the fasteners can be solvable without tools in order to open the flap or the lid by hand.
  • at least one pair of profile elements can preferably limit the receiving opening of the receptacle laterally.
  • the pro- Filetti can have a solid profile, the cross section is smaller in particular than the at least one other of the total of at least three profile elements.
  • At least one of the profile elements is preferably formed as a hollow profile.
  • the hollow profile may in particular be arranged on the bottom of the receptacle and / or opposite the receiving opening.
  • the cross-section of this profile may be larger than the profile of profile elements located on the sides of the receptacle to accommodate high loads.
  • a single profile element with respect to the receiving opening and a plurality of separate profile elements or a multi-chamber profile can be used.
  • the triangular arrangement of the profile elements opposite and on both sides of the receiving opening leads to a high rigidity due to the distance between the profile elements.
  • the arrangement of the profile elements on both sides of the recording also helps that the two-wheeled accessories is better protected in the recording.
  • the two profile elements located laterally of the receptacle shield the profile arranged opposite the receiving opening in the event of lateral falls.
  • the at least two profiles arranged laterally of the receptacle can be rectangular profiles, the longitudinal sides of which run parallel to the plane spanned by the bicycle frame; the at least one profile arranged opposite the receiving opening can likewise be rectangular and extend with its longitudinal side transversely to the at least two other profiles. At least one rectangular profile can limit the reception towards the frame interior. This profile can be used as a stop for the bicycle accessories to be inserted into the receptacle.
  • the profile elements are preferably intact, ie not weakened by large recesses or recesses. If necessary, small tapped holes can be present in order to mount components such as plug connectors or holders in the receptacle.
  • the frame part with the profile elements can form a seat and / or down tube of the bicycle frame, because these two frame parts usually reach as far as the lowest point of the bicycle frame, the bottom bracket.
  • the receptacle is arranged closer to a ground-level node of the frame part as at a remote node.
  • the ground-level node may be located in particular in the area of a bottom bracket or on the bottom bracket.
  • the frame part with the profile elements is a down tube of the bicycle frame and the receptacle opens downwards in the direction of a front wheel.
  • this embodiment also ensures sufficient space for unhindered installation of the accumulator or accessory. To mount only the front wheel has to be taken in order to get enough space.
  • the seat tube for receiving a battery or other bicycle accessories is disadvantageous because behind the rear wheel blocks the recording and forward the remaining frame parts only little space.
  • the profile elements spanning the receptacle can be brought together at at least one end located in their longitudinal direction and, in particular, connected to one another at a common connection point.
  • at least one profile element can be bent.
  • the profile elements can be connected in the same way with the remaining frame parts, as a conventional frame part of a single pipe section.
  • the profile elements can be connected to at least one longitudinal end with a substantially extending in the direction of the profile elements tube. This also makes it possible to use the profile element having frame part instead of the conventional frame parts.
  • the profile elements may extend adjacent to each other to form a node.
  • the profile elements may extend continuously between two nodes of the two radrah mens to obtain a high strength.
  • the continuous course leads to an unimpeded flow of force through the profile elements. Since the profile of the profile element is not interrupted, there are no notch effects and there are no permanent endangered seams in the middle of the frame part.
  • the profile elements spanning the receptacle can, at least in sections, be an integral part of an extrusion profile which forms the U-shaped receiving cross section.
  • the reinforcing walls can also be formed from the extrusion profile.
  • the invention also relates to an electric bicycle with an electric motor and a two-wheel frame having any combination of the features described above.
  • at least one accumulator of the electric bicycle can be arranged in the receptacle spanned by the profile elements.
  • the power flow is preferably passed by the profile elements on the accumulator, so that the accumulator remains free of force.
  • the receptacle can accommodate any accessories.
