    Bicycle frame with built-in and removable battery Field of the invention
    BACKGROUND OF THE INVENTION The present invention relates to a method of producing an extruded frame member with a battery pack profile for use with a bicycle frame comprising a plurality of frame members wherein the frame members are interconnected and constitute a structure of such rigidity that the bicycle frame does not change the geometric shape under normal load.
    The present invention further relates to a bicycle frame comprising a plurality of frame elements, including at least one frame member, wherein the frame members are interconnected and constitute a structure of such rigidity that the bicycle frame does not change, in ordinary load, in a geometric shape, at least partially embedded is an electric battery system comprising at least one battery pack for storing electrical energy for use with equipment such as comfort equipment and / or safety equipment on a bicycle, including an electric auxiliary motor.
    BACKGROUND OF THE INVENTION
    It is generally known to use batteries in connection with bicycles for use, for example, energy supply for lamps. Also, it is well known to use battery systems on bicycles for use of energy supply to electric auxiliary motors.
    Thus, bicycles with electric auxiliary motors have a battery system with at least one battery pack, which is located somewhere on the bicycle. In the past, it was common to place the battery pack under or in connection with the luggage carrier, or in connection with the saddle, but in newer models of so-called electric bicycles or just electric bicycles, the battery packs have been built into or built into the bicycle rack itself, which means that an electric bicycle is also not easily recognizable. .
    The problem with battery packs is that they need to be recharged and since it is impractical to bring the entire bike to a power source such as an outlet, it is therefore necessary to be able to take off the bike's battery pack.
    For the above reason, it is therefore also well known to make recesses in bicycle frames, which thus leaves room for battery packs, with the disadvantage that the recesses result in a substantial weakening of a traditional bicycle frame design.
    However, the above problem can be solved, for example, as stated in DK 176497 B1, from which a bicycle frame is known, comprising a number of frame elements, preferably tubes, the frame elements being interconnected and constituting a structure with such rigidity that the bicycle frame does not change geometrically under normal load. in which the part of the frame arranged for mounting a battery pack is constituted by a multi-chamber profile, with at least one chamber in the multi-chamber profile being intact. This results in a bicycle frame with a recess for a battery pack where the frame has a high stiffness.
    It is also known to place a square profile in a round tube and thus also create a profile in which there are more chambers and thus have an increased strength.
    The object of the invention
    The object of this invention is to solve the problem of stability of bicycle frames in a much better, faster and cheaper way than previously known by not just using multi-chamber profiles to obtain sufficient strength, but at the same time solving the problem so that the bicycle frame becomes so discreet as possible.
    It is thus the object of this invention to provide a much better, faster and cheaper solution where it is not necessary to weld different constructions together to form, for example, a lower tube which may have an opening for the battery pack.
    It is further the object of the invention that the finished profile in the production process is extruded with variable thicknesses, for example, where there is a greater thickness of part on the profile than on other parts, as necessary to obtain sufficient strength. The production process also aims to be able to make a recess that is carefully adapted to at least one battery pack.
    It is also an object of the invention to extrude the battery pack in a form which causes the bicycle frame where the battery pack is inserted to appear as a '' molded '' optical unit. This means that the battery pack does not appear as a foreign element, but is part of the overall aesthetic design of the bike, without the battery pack appearing as an extra part of the bike.
    Finally, the object of the invention is to provide a bicycle frame with a built-in and removable battery, the battery of which is essentially built into the frame, from which it can be easily removed for charging, replacement or to prevent theft.
    Description of the Invention
    According to a first aspect of the invention, the above object is achieved by a method as initially described and as described in the preamble of claim 1, comprising a method of manufacturing an extruded battery pack profile frame for use with a bicycle frame comprising a plurality of frame elements, wherein the frame elements are interconnected and constitute a structure with such rigidity that the bicycle frame under ordinary load does not change the geometric shape, where the at least one frame element is extruded with variable thicknesses in a given cross-sectional profile.
    This allows the desired and necessary strength to be obtained at the various locations of a frame member to make the frame member sufficiently stable. It can be particularly on the sides of the frame element that there is a specially adapted thickness and thus an increased stiffness in the profile.
    The extrusion of the frame element itself can take place using a wide variety of materials, such as, for example, aluminum, stainless steel, other metals and alloys, and a wide variety of plastic types / polymers. A frame member may also be manufactured by casting or by pultrusion and may, for example, be made of fiber-reinforced plastic types.
    In another aspect, the present invention also relates to a method in which a recess is made in at least one extruded frame member.
    This makes it possible to obtain an opening in the extruded frame member suitable for the part of a battery pack to be included in the bicycle frame. The recess may in a preferred embodiment be located at the top of the extruded frame member (s), but alternatively may also be placed in many other ways.
    In a third aspect, the present invention also relates to a method in which the at least one battery pack profile is extruded.
    The extrusion of the battery pack profile can also be carried out using a wide variety of materials, such as, for example, aluminum, stainless steel and a wide variety of plastic types / polymers.
    This also makes it easy, fast, practical and economical to make a profile suitable for the batteries used, and where the profile also fits the extruded frame element. In a preferred embodiment, the profile of the battery pack is made of the same material as the frame member. If this material is, for example, aluminum, the battery and frame can both be anodized in different colors both for good design and for increased strength in material and surface against scratches. In one embodiment, the profile is also extruded with variable thicknesses that either extend from the profile, for example, at the bottom or extend into the profile, which also increases the strength and stability of the bicycle frame.
    The present invention also relates, in a fourth aspect, to a method in which the at least one battery pack profile is inserted into the recess of the at least one extruded frame member.
    This makes it possible to obtain a discrete bicycle frame comprising at least one battery pack.
    The present invention also relates, in a fifth aspect, to a bicycle frame, the frame comprising at least one extruded frame element of varying thicknesses comprising a top, a bottom, a first side and a second side, an inner side and an outer side, and at least a recess having at least one battery pack comprising a cross-sectional profile having a first portion and a second portion, and wherein the at least one battery pack's first portion together with the cross-sectional profile of the frame member in the recess is complementary to the frame section's cross-sectional profile prior to the recess.
    This makes it possible to place at least one battery pack on a bicycle where the battery pack does not appear as an extra mounted and independent unit, but where the battery, on the other hand, appears very discreetly as an integral part of the bicycle frame.
    By extruding the frame member, it is further possible to place goods on the frame member where it is appropriate to obtain sufficient strength to compensate for the at least one recess for the at least one battery pack.
    The recess thus allows the battery pack to be inserted into the frame element itself, where the sides in a preferred embodiment support and hold around the sides of the battery pack.
    In a preferred embodiment, the extruded profile of the frame is oval, round, or a combination thereof. This means that the higher the sides of the frame element are in the recess, the narrower the battery becomes in order to go down into the recess. However, in a preferred embodiment, the sides of the frame member will extend over such a large portion of the battery that the center of gravity of the battery will cause the battery to lie securely in the recess of the frame member.
    The extruded frame member with the recess is in a preferred embodiment also located on the part of the bicycle frame that goes from crank to crown tube, namely in the lower tube, but could in principle also be located on other parts of the bicycle frame, for example on the part that goes from crank for saddle, namely in the saddle tube, but placement in the upper tube is also an option. In a further preferred embodiment, the first part of the battery pack profile is of the same exterior size and shape as the frame element - and thus fits precisely in the recess, so it will be to regard the frame with the battery pack as a continuous tube both visually but also in terms of strength. The battery profile will be able to transmit compressive forces in the event that the frame element is subjected to bending, since the profile of the battery pack replaces the profile of the frame. This will be the case regardless of whether the frame element alone is strong enough not to deform without the battery pack inserted.
    It is implied that there are means for interconnecting the battery pack with the electrical components on the bicycle such as lights, capacity indicator and auxiliary motor by means of switches, terminals, connection sockets, wires and more.
    It is further implicit that, of course, there are means for holding the battery pack in the frame member so that the battery pack does not fall off the bike or out of the recess.
    The present invention also relates, in a sixth aspect, to a bicycle frame, wherein the at least one extruded frame member comprises a recess on the bottom of the inner side of the frame member, and wherein the at least one battery pack's second portion comprises a protrusion, the recess and protrusion being complementary.
    This makes it possible to place the at least one battery pack faster and more securely in the recess of the frame element.
    The present invention also relates in a seventh aspect to a bicycle frame, wherein the at least one extruded frame element has the largest thickness of the bottom and the first side and the second side have a greater thickness of thickness than the top.
    This makes it possible to reconcile the necessary strength ratios in the frame member, whereby a smaller thickness of goods can be compensated for at a location in the member by supplying goods to other selected locations of the frame member.
    The present invention also relates, in an eighth aspect, to a bicycle frame, the at least one extruded frame element further comprising a channel on the outside.
    This makes it possible to route cables and / or wires and brake pipes in all or part of the length of the frame, where the cables are easily accessible and thus easily and quickly can be serviced and replaced as desired and needed. At the same time, a faster and less complex mounting of the bicycle is obtained during the manufacture thereof. In a preferred embodiment, the duct is provided with restraints for cables and wires.
    The present invention also relates, in a ninth aspect, to a bicycle frame, the duct comprising a closure device, the outer duct and the closure device having cooperative closing devices.
    This makes it possible to completely close the channel by means of a lid, rail or the like, which can, for example by means of clips, be attached to the outside channel of the bicycle frame. Said clips may be an integral part of the lid itself and may in a variant be created by the design of the lid itself, as will be seen in the drawing description and the figures.
    The advantage of this is to protect cables and wires etc. from dirt as well as to give a design beautiful appearance of a closed frame element, which contains both the battery and the necessary electrical components. A further advantage is that the cables are faster to install and at the same time much easier to get to if a repair is needed. Thus, it is easier to service when cables are not in tubes as usual, but are easily accessible by, for example, removing the lid attached to the duct with clips.
    The present invention also relates in a tenth aspect to a bicycle frame, wherein the at least one battery pack comprises a cross-sectional profile with an outer shape, the first part of which is visible and the second part hidden when the battery pack is inserted into the recess of the frame element.
    This makes it possible to make a bicycle frame where the visible part of the battery pack forms a natural and discreet part of the whole bicycle frame in the cross section of the bicycle frame where the battery pack is located.
    The batteries themselves can be of all possible batteries, such as 24 Volt or 36 Volt rechargeable lithium-ion (Li-Ion) batteries / battery cells. Character description
