Definitions

  • the present invention relates to a bicycle frame, in particular for an e-bike.
  • the invention further relates to an electric bicycle, everything in accordance with the preambles of the independent claims.
  • Electric assisted bicycles are becoming increasingly popular as they largely meet the increasing demand for reliable, safe and sustainable mobility.
  • An electric bicycle is a bicycle that uses an electric motor to assist pedalling. Pedaling becomes easier. The motor supports the pedaling movements and amplifies or takes over completely.
  • Such an electric bicycle is also referred to as an e-bike, pedelec or speed pedelec.
  • e-bike pedelec or speed pedelec.
  • a bicycle frame for accommodating a battery unit and associated battery unit is known from the prior art, for example from EP 2230164 B1.
  • the frame has a tubular section with an interior space that houses a battery pack.
  • a side opening extends in the direction of extension of the tube section.
  • the battery unit is inserted into the interior through the side opening.
  • An arrangement of the battery in the pipe section has advantages.
  • An e-bike bicycle frame is known from EP3437977A1, which has an upper tube, a lower tube and a saddle tube. Furthermore, a bottom bracket is arranged in a housing, which can be a bottom bracket receiving element. If necessary, the electric motor is also provided in the housing. A battery is also connected to the down tube. Arranging the battery on the down tube has the disadvantage that it is difficult to lay cables, hydraulic lines and, in particular, shift cables such as Bowden cables. A channel element is therefore arranged to the side of the battery. This is used to hold cables, shifter cables, brake cables and/or hydraulic lines.
  • the bottom bracket is arranged in a bottom bracket mount and connected to an electric motor.
  • gear ratio is important.
  • more and more gears with gears are also being used on electric bicycles, where gears mesh and thus ensure a translation.
  • gears with different numbers of teeth are brought into contact.
  • Electrical or electronic circuits are operated by means of a battery or an accumulator.
  • gears are an important component for an e-bike. It should be easy to use and low-maintenance.
  • hub gears are also known, which are usually integrated in the rear hub.
  • Bottom bracket gears such as those from Pinion.
  • Bottom bracket gears have a large number of gears with a large transmission range and are generally low-maintenance.
  • Hub gears and bottom bracket gears have the advantage that they can be combined with belts, which reduces maintenance.
  • the housing of a bottom bracket gear can be connected to the frame and is usually flanged to the frame from below.
  • the frame roughly corresponds to the width of the case.
  • the supply cables are routed into the housing so that they can be seen from the outside. Presentation of the invention
  • a bicycle frame with an integrated transmission for an e-bike which has a high level of acceptance among users in terms of functionality and applicability.
  • the named bicycle frame with the integrated gear should preferably be as safe as possible in operation and also particularly easy to maintain and provide enough space for cable routing.
  • the bicycle frame comprises a first frame section with an interior space for accommodating at least one battery unit, a second frame section which adjoins the first frame section and runs to a rear wheel mount, and a frame section-associated receiving area for a gear unit.
  • the first frame section, the second frame section and the receiving area are designed such that cables run essentially within the first frame section and the second frame section and essentially only cables that are used to connect the transmission unit are routed into the receiving area.
  • the design of the frame allows the gear unit to be integrated into the frame. There is still enough space for cable routing. Due to the hidden installation, a wide variety of gear units can be installed without it being visible from the outside which gear is involved. In addition, the gearbox is largely protected from external influences or damage.
  • the frame essentially encloses the gear unit and thus protects the gear unit.
  • the transmission unit is nearly enclosed or covered.
  • the gear unit is completely enclosed and covered, so that the gear unit is not visible from the outside.
  • the cables to be routed can include an electrical cable, a shift cable, a brake cable and/or a hydraulic line. It is advantageous that additional cables can be routed in the frame.
  • the receiving area has an at least semicircular or arcuate recess or opening on both sides. This gives the frame better stability. In addition, a simple assembly of the drive unit is possible. In a special embodiment, the receiving area is adapted to the contour of the transmission. The gearbox or the gearbox unit is thus integrated into the frame and is therefore better protected. A special advantage is that due to the hidden installation, a wide variety of gears or gear units can be installed - even exchanged - without this being visible from the outside. The frame can therefore be given a different or special shape.
  • the frame construction offers sufficient stability and enough space for cables.
  • the e-bike with integrated gear is particularly easy to maintain, since all necessary or required accesses are guaranteed.
  • the existing mechanical integration can be supported or supplemented with an electrical integration.
  • the transmission of the e-bike can be controlled by a certain "intelligence". This can be done using a protected data cable inside the frame or a wireless solution. Based on user behavior, routing and/or battery status, optimal support or gear ratios can be determined and implemented using computer technology, for example.
  • the receiving area has a flat surface on the inside. This makes it possible to provide a base plate that can be anchored or welded well inside the frame. Fastening elements can be provided on it, which hold the drivenness securely. No weld seams are therefore visible from the outside. The gear can rest on or be attached to the base plate. As a result, high stability can be guaranteed even with heavy pedal loads.
  • the receiving area advantageously includes a lead-through area for routing the cables.
  • This has the advantage that the passage is accessible from the outside, if the gearbox is or will be dismantled. Without such a "simple" access, it is often very time-consuming to route lines and cables during assembly and when servicing, ie from the first to the second frame section or vice versa.
  • the drive unit can be installed using screw connections.
  • the cable connections are made inside the recording area.
  • the recording area is provided with a decorative screen from the outside.
  • the frame geometry can ensure that loads from a drive belt or pedal force are tolerable for the frame.
  • the second frame section immediately follows the first frame section, so that no interruptions occur. No additional connections are therefore necessary, but the required strength and functionality are provided.
  • the second frame section is preferably designed in the form of a fork after a seat tube, so that a rear wheel can be attached and stored at the end.
  • the second frame section runs to the rear triangle, which is also connected to the seat stays.
  • the result is an overall stable frame shape that can also withstand heavy loads.
  • the first frame section, the receiving area and the second frame section have a cable routing area on the inside. It is particularly advantageous that the cable routing area is designed to be continuous. This allows cables to be routed to the rear wheel axle on the inside. Mechanical damage from the outside can be largely ruled out and prevented.
  • Another aspect of the present invention relates to an electric bicycle that includes a bicycle frame according to the invention.
  • the bicycle frame includes all components and parts that are necessary for the safe operation of an electric bicycle.
  • FIG. 1 shows a right side view of an e-bike with a bicycle frame according to the invention

  • the bicycle 1, also referred to as an e-bike, comprises a bicycle frame 2.
  • the bicycle frame 2 has a first frame section 10 and a second frame section 20, which adjoins the first frame section 10 and runs to a rear wheel suspension or rear wheel mount 5.
  • the first frame section 10 has an interior space 12 for accommodating a battery unit 3, which is shown schematically in FIG.
  • the battery unit 3 supplies the energy for an electric motor 4 arranged on the rear wheel.
  • Such an electric motor 4 can be used both as a complete bicycle drive and as a hybrid drive, in which the muscle power of the cyclist is supported depending on the drive force transmitted to the rear wheel by the pedal drive .
  • a drive unit which is designed as a chain or belt, runs from the front sprocket to the rear sprocket.
  • the frame structure consists essentially of a seat tube 6, a top tube 8 and the first frame section 10, which are arranged in a triangular shape, as well as a front steering head tube 9 and two seat tube struts 7 arranged at the rear of the frame and the second frame section 20, which is directly connects to the first frame section 10 and is guided to the rear wheel suspension 5 by rear wheel struts.
  • the first frame section 10 has a cross-sectional shape that is stretched in the plane of the frame, so that an enlarged frame cross-section is created.
  • a transmission unit 40 is provided at the lower end of the first frame section 10 .
  • the gear unit 40 eliminates the need for a derailleur.
  • the transmission unit 40 increases or decreases the driver's power, for example on the belt.

  • the bicycle frame 2 in turn essentially consists of the seat tube 6, the top tube 8 and the first frame section 10, as well as the two seat tube stays 7 arranged on the rear of the frame and the second frame section 20.
  • the e-bike 1 also includes, as shown in Fig. 1 and Fig. 2, a front wheel and a rear wheel, handlebars with grips and gears, a saddle that is connected to the seat tube 6, an optional luggage rack, a side stand or short Stand 13, brakes and lighting.
  • the gear unit 40 is clearly visible in the left side view.
  • the bottom bracket with the pedals is right next to it.
  • the transmission unit 40 is arranged in an accommodating area of the bicycle frame 2 and is covered with an ornament panel 42 .
  • the transmission unit 40 is located in the transition between the first frame section 10 and the second frame section 20.
  • the bicycle frame 2 with the receiving area is designed in such a way that cables run essentially within the first frame section 10 and the second frame section 20. Cables that serve to connect the transmission unit 40 , are routed directly to the transmission unit 40. No cables are visible from the outside.
  • the circuit provided on the handlebar is connected to the gear unit 40 .
  • a cable guide runs in the first frame section 10 to the receiving area of the transmission unit 40.
  • Further cables, e.g. B, from the battery unit 3 to the electric motor 4 run from the first frame section 10 to the second frame section 20 without leaving them beforehand.

  • a mostly internal cable routing is achieved, which prevents damage to the cable and thus leads to less maintenance.
  • 3 shows a bicycle frame 2 according to the invention without further accessories.
  • the bicycle frame 2 consists of an aluminum alloy, for example aluminum 6061 (AIMgl SiCu). In connection with appropriate artificial aging (solution annealing), better elongation behavior can be achieved with this alloy. In the event of damage, the tube only deforms a little more before it breaks, thus offering more safety reserves.

  • the seat tube 6 is directly connected to the frame section in the upper area and thus guarantees stability for the frame 2.
  • the receiving area 30 includes a lead-through area 33 which connects the first frame section 10 and the second frame section 20 .
  • the lead-through area 33 has a number of openings which allow good access when the transmission, ie the transmission unit 40, is not installed. This simplifies the assembly and service in terms of accessibility of the cables, which pass through pipes, ducts, and/or directly in the first frame section 10 and the second Frame section 20 are performed.
