Description

The invention relates to a bicycle frame and a bicycle with such a bicycle frame.

Bicycles have always been a popular means of transportation.

There are a variety of types of bicycles, for example in the form of so-called city or city bicycles, which have more traditional bicycle frame and are characterized by a slightly heavier construction.

In addition, there are, for example, so-called mountain bikes, which usually have a spring-loaded front fork or at least a sprung rear triangle.

Furthermore, racing bikes are known, which are characterized by the use of very narrow tires. Bicycle frames for racing bikes, for example, compared to the bicycle frame of so-called city bikes or mountain bikes designed much more graceful. In addition, bike frames made of carbon are preferably used today for road bikes in order to save weight.

In order to increase the mobility, especially of older people, many bicycles are equipped with additional drives, especially electric drives in the modern day. Such a drive is usually provided in the bottom bracket shell, wherein an energy store, in particular in the form of a rechargeable battery, is arranged on or in the frame tubes or on the luggage carrier.

Via a corresponding control device, which is arranged in particular on the handlebar, the amount of support can be adjusted by the electric drive.

Accumulators that are clearly visible from the outside on a bicycle, not only visually disturbing, they can also be the target of vandalism or theft. For this reason, many attempts to integrate the batteries in a frame tube of the bicycle frame. From the EP 2 134 592 B1 Such bicycle frames are known. This bicycle frame comprises a plurality of frame tubes, wherein a frame tube has a recess into which a battery group is introduced. The frame tube comprises several chambers, wherein only one chamber is at least partially penetrated by the recess.

A disadvantage of the EP 2 134 592 B1 is that the battery group or the outer housing of the battery group co-determines the aesthetic appearance and the shape of the bicycle frame significantly. However, bicycle manufacturers have little influence on the design of the outer housing of the battery group, because this is purchased as a purchased part.

It is therefore the object of the present invention to provide a bicycle frame with a battery module, wherein the battery module housing can be transformed by simple means such that the shape of the bicycle frame can be easily adapted to a desired specification.

The object is solved by the bicycle frame according to claim 1 and by a bicycle comprising such a bicycle frame by the claim 22. In claims 2 to 21 further developments of the bicycle frame according to the invention are indicated.

The bicycle frame according to the invention comprises a plurality of interconnected, for example, welded frame tubes, wherein at least one frame tube, which extends in the longitudinal direction, has a receiving opening at its peripheral region over a partial circumference, whereby a tube interior of the at least one frame tube is accessible from outside the bicycle frame via this peripheral region , As a result, a battery receiving space is formed. In this battery receiving space, a battery module is arranged, wherein the battery module also comprises a battery module housing. The battery module housing also extends in the longitudinal direction and extends in the inserted state in the longitudinal direction of the at least one frame tube. A battery module housing top of the battery module housing points in the direction of the receiving opening. The battery receiving space is closed with the battery module inserted through a closure lid, wherein an inside of the closure lid points in the direction of the battery module. The bicycle frame further comprises a fastening device which mechanically (detachably) connects the closure lid to the battery module housing. The fastening device comprises at least one first retaining and guiding groove and at least one first retaining web. These are arranged either on the closure lid or on the battery module housing. In particular, the at least one first holding and guiding groove is formed in the accumulator module housing upper side of the accumulator module housing and preferably extends in the longitudinal direction, the at least one first holding web projecting on the inside of the closure lid in the direction of the accumulator module. The arrangement of the first retaining and guiding groove and the first retaining web on the battery module housing and on the closure cap could also be reversed. The at least one first retaining and guiding groove comprises in cross-section a (hollow) groove receiving region and a (hollow) groove opening region, the groove receiving region becoming wider is as the Nutöffnungsbereich and wherein the groove receiving portion is accessible in cross section over the Nutöffnungsbereich from outside the holding and guiding groove. Due to the different size of the groove receiving area compared to the groove opening area results in an undercut bearing area, for example in the form of a support shoulder. The difference in size results, therefore, in that the groove opening portion does not merge along the entire width of one side of the groove receiving portion into the groove receiving portion. The at least one first retaining web engages over the groove opening area in the groove receiving area of the at least one first retaining and guiding groove and engages behind the undercut bearing area, so that the at least one first retaining web is displaceable only along the at least one first retaining and guiding groove. Pulling off transversely or perpendicular to the extension direction (longitudinal direction) of the at least one first holding and guiding groove is not possible.

Particularly advantageous is the use of the first holding and guiding groove and the first holding web, because this tool-free a corresponding cap can be mounted on the battery module housing. This is advantageously achieved in that the closure lid can be pushed onto the battery module housing only with a movement vector which runs along the holding and guiding groove. The battery module housing thereby has the form which the manufacturer of the accumulators pretends, whereas the closure cover can be designed by the bicycle manufacturer according to the desired function and the visual appearance (for example the color) itself.

With regard to its cross-sectional shape, the at least one first retaining web is adapted to the cross-sectional shape of the groove receiving region (undercut bearing region) of the at least one first retaining and guiding groove. Preferably, the at least one first retaining and guiding groove is T-shaped in cross-section. In such a case, the at least one first retaining web could also be T-shaped or L-shaped. In principle, it would also be possible for the holding and guiding groove to be L-shaped, which in this case would also apply to the first holding bar. This can be achieved in a particularly advantageous manner, an undercut support area.

In a further exemplary embodiment, the battery module with its battery module housing can be connected to the closure lid only outside the battery receiving space by the fastening device. This prevents the cap from coming off while driving.

In a further exemplary embodiment, the bicycle frame also comprises a latching device which is arranged on the at least one first holding web and on the at least one first holding and guiding groove or on the battery module housing and the closure lid such that, in the event that the at least one first holding web Holding web is inserted by a predetermined length in the at least one first holding and guiding groove, a further displacement is possible only with an increased force component. The latching device comprises in particular a ball catch. The predetermined length is preferably the final length. As soon as this is achieved, the at least one holding web and the at least one first holding and guiding groove are in an optimum orientation or position relative to each other. In this case, the cap fits optimally to the battery module housing and can be easily inserted into the battery receiving space. This further simplifies the production.

In addition to a first holding web and a first holding and guiding groove, there may also be at least one second holding web and at least one second holding and guiding groove, which are arranged parallel to the first holding web or to the first holding and guiding groove. The structure corresponds to that of the first holding web and the first holding and guiding groove. In principle, it may be that the attachment of the second holding web and the second holding and guiding groove on the inside of the closure lid and the battery module housing top of the battery module housing is reversed compared to the attachment of the at least one first holding web and the at least one first holding and Guide groove on the inside of the cover and on the battery module housing top of the battery module housing.

In a preferred embodiment, the closure lid comprises on the inside an at least partially or completely circulating support region, whereas the at least one frame tube comprises an at least partially or completely encircling support edge, which is formed by the receiving opening. The closure lid rests on its at least partially or completely circulating support region on the at least partially or completely circumferential support edge of the at least one frame tube. This achieves a particularly flush conclusion. In particular, the diameter of the at least one frame tube at the point at which the closure lid is introduced does not increase in relation to another location of the at least one frame tube, where there is no closure lid. This can mean that the at least one frame tube can continue to have a round diameter, for example.

In a further preferred embodiment, the at least partially or completely circulating support region of the closure lid comprises a support shoulder, wherein a seal is introduced between this support shoulder and the at least partially or completely circumferential support edge of the at least one frame tube. This seal is preferably firmly connected to the support shoulder of the closure lid in a 2K injection process or attached to the support shoulder via an adhesive method.

In a further preferred embodiment, the bicycle frame comprises a lock device, which is firmly connected to the at least one frame tube. The lock device can be switched back and forth between a release position and a shut-off position. The lock device is either releasably connected to the battery module housing or detachably connected to the closure lid. In principle, it could also be releasably connected to the battery module housing and the closure lid. In the release position, the battery module housing can be used together with the closure lid in the battery receiving space and removed from the battery receiving space. This is not possible in the shut-off position. Here, the battery module housing and the closure lid are arranged locked in the battery receiving space.

The bicycle according to the invention comprises such a bicycle frame.

1 shows an exemplary bicycle frame 1 , bicycle frame 1 can be constructed in different variations.

The shown conventional bicycle frame 1 has several frame tubes 2 which are preferably welded together. Usually there is a seat tube 2a , which carries a height-adjustable and lockable seat post with a final bicycle saddle.

Furthermore, the bicycle frame includes 1 a tubular headset 2 B , which is interspersed by a head tube. At the bottom over the tubular headset 2 B projecting portion of the head tube, a bicycle fork is added to the axis of the front wheel is attached.

It also includes a classic bicycle frame 1 a the seat tube 2a and the tax rate 2 B connecting top tube 2c and down tube 2d ,

The down tube 2d and the seat tube 2a are usually about the bottom bracket shell 3 connected with each other.

Finally, there is the so-called rear triangle 4 provided, at the dropout 4a the wheel axle of the rear wheel is attached. The dropout 4a is with the seat tube 2a and / or with the bottom bracket shell 3 over chainstays 4b connected. The dropout 4a is also about rear struts 4c with a higher section of the seat tube 2a connected, which are each formed in pairs, to take in between the rear wheel.

In sprung rear end constructions usually the rear triangle 4 then not to the bicycle frame 1 added.

Deviating from many bicycle frame structures have become known in which, for example, the top tube 2c completely missing or as a lowered or lower top tube 2c is provided, which, for example, on the seat tube 2a only at a small distance above the bottom bracket shell 3 ends or for example via the seat tube 2a out to the dropout 4a is extended. For example, bicycle frames are also known 1 in the form of a so-called cross frame, in which a larger forces receiving central arm section is provided which the tax rate 2 B directly with the dropout 4a combines.

Furthermore, different bike frames differ 1 of course, the different design of the individual the bicycle frame 1 forming sections. Different bicycle frame sizes are offered, which are adapted to the height of the cyclist.

To provide bicycles with additional electrical drives, energy storage devices are necessary. Such energy storage devices are in particular in the form of accumulator modules 5 in front. These battery modules 5 can in different places of the bicycle frame 1 or the bicycle. For example, a battery module 5 on the seat tube 2a , the top tube 2c , the down tube 2d or be mounted on the luggage rack, for example. Such a visible attachment of the battery module 5 However, the result is that the cyclist is restricted when using the bicycle or the appearance is disturbed.

Therefore, the battery modules are being used in particular 5 at least partially in the at least one frame tube 2 to integrate. The at least one frame tube 2 in which it is in particular the seat tube 2a , the top tube 2c and / or the down tube 2d is made of an electrically conductive metal, in particular of aluminum, and is preferably produced in an extrusion or hydroforming process. The frame tube 2 is therefore hollow and comprises a tube interior 6 as in the cross section through the frame tube, for example 2 in 4A is shown.

Such a pipe interior 6 is also in the spatial view of the at least one frame tube 2 out 2 refer to. The at least one frame tube 2 is open at its ends 2 ₁ , 2 ₂ and can at the corresponding end faces with another frame tube 2 be welded.

After the individual frame tubes 2 together to the bicycle frame 1 are welded, these are painted or powdered.

The at least one frame tube 2 extends in the longitudinal direction 7 and has at its peripheral region or its peripheral surface a receiving opening 9 on what a battery storage room 6a in the pipe interior 6 is formed. The battery receiving space 6a of the at least one frame tube 2 is therefore outside the bicycle frame 1 accessible. The battery receiving space 6a is accessible in particular from the peripheral region, ie with a movement vector transversely or perpendicular to the longitudinal direction 7 ,

In this battery receiving space 6a is the battery module 5 arranged (see 4A) , where the battery module 5 a battery module housing 8th with a battery module housing top 8a includes. The battery module housing 8th with its battery module housing top 8a is in the 4A and 4B and Figures 5A and 5C. The battery module housing 8th runs in the inserted state in the battery receiving space 6a also in the longitudinal direction 7 of the frame tube 2 , The battery module housing top 8a points in the direction of the receiving opening 9 ,

The battery receiving space 6a is with the inserted battery module 5 through a closure lid 10 closed, with an inside 10a the closure lid 10 in the direction of the battery module 5 shows. In the assembled state, ie when the battery module 5 in the battery receiving space 6a is used, is only the cap 10 from outside the bicycle frame to see the receiving opening 9 closes. This is for example in the 2 . 3A and 3B shown.

The cap 10 is preferably made in one piece. It can be made of plastic or metal.

The battery module housing 8th can also be made of plastic or metal.

In 2 is shown that the cross section of the at least one frame tube 2 by using the battery module 5 using the cap 10 for closing the receiving opening 9 remains essentially the same. The wording "essentially" means that the scope of the frame tube 2 at the area where the receiving opening 9 with the cap 10 is closed, compared to other areas in which no receiving opening 9 in the peripheral region of the frame tube 2 is increased by less than 15%, 10% or 5%.

The receiving opening 9 can be over the entire length of the frame tube 2 extend or only over a partial length.

The cap 10 is designed such that the appearance of at least one frame tube 2 does not change significantly. The cap 10 is therefore with regard to its shape, in particular its outer geometry, to the course of the at least one frame tube 2 customized.

The cap 10 is with the battery module 5 So with the battery module housing 8th mechanically releasably connected. This is a fastening device 11 envisaged as they are in terms of 4A . 4B and FIGS. 5A to 5D will be explained in more detail below. The fastening device 11 connects the cap 10 with the battery module housing 8th , This connection is a screwless, threadless, solderless and / or tack free connection. The connection is detachable without damaging the battery module housing 8th and on the cap 10 occur.

According to the invention, the battery module housing 8th together with the cap 10 before insertion into the battery compartment 6a preassembled. In particular, the closure lid can be 10 only to the battery module housing 8th mount when the battery module 5 not in the battery receiving space 6a is used. An assembly of the cap 10 with the battery module housing 8th is preferably only outside of the battery receiving space 6a possible.

The fastening device 11 is formed such that the closure lid 10 by means of a sliding movement in a mechanical connection to the battery module housing 8th can be brought. For this purpose, the fastening device comprises 11 at least a first retaining and guiding groove 12a and at least a first jetty 13a , It will be here on the 4A . 4B and 5A to 5D directed. The first holding and guiding groove 12a is in the battery module housing top 8a formed, wherein the at least one first retaining web 13a from the inside 10a the closure lid 10 towards the battery module housing top 8a protrudes. In principle, the attachment could also be reversed, after which the first retaining web 13a on the battery module housing top 8a is formed and the first holding and Führungsnot 12a on the inside 10a the closure lid 10 is trained.

The at least one first retaining and guiding groove 12a comprises in cross section a groove receiving area 12a ₁ and a groove opening area 12a ₂ , The groove receiving area 12a ₁ is wider than the slot opening area 12a ₂ (Width corresponds to the profile in the cross section of the groove receiving area 12a ₁ and the groove opening area 12a ₂ parallel to the battery module housing top 8a ). It is on the 5A and 5C directed. The groove receiving area 12a ₁ is over the slot opening area 12a ₂ in cross section from outside the holding and guiding groove 12a accessible. Parts of the groove receiving area 12a ₁ not directly with the slot opening area 12a ₂ are connected, form an undercut support area 14 ,

The at least one first jetty 13a reaches over the slot opening area 12a ₂ in the groove receiving area 12a ₁ the first holding and guiding groove 12a and engages behind the undercut support area 14 so that the at least one first jetty 13a only along the at least one first holding and guiding groove 12a is displaceable. The first jetty 13a is not the first holding and guiding groove 12a removable with a motion vector which is perpendicular to the motion vector, with the holding web 13a in the holding and Führungsnot 12a is moved.

Preferably, the first retaining and guiding groove extends 12a over most or all of the length of the battery module case top 8a or the inside 10a the closure lid 10 ,

In particular, the first holding and guiding groove extends 12a longitudinal 7 or with a component predominantly in the longitudinal direction 7 along the battery module housing 8th or along the closure lid 10 , Alternatively, it could also be perpendicular to the longitudinal direction or with a component predominantly perpendicular to the longitudinal direction 7 of the battery module housing 8th or the closure lid 10 run.

The same applies to the first landing stage 13a , This preferably also runs in the longitudinal direction 7 or with a component predominantly in the longitudinal direction 7 ,

The first jetty 13a and the first holding and guiding groove 12a preferably run along a straight line and are designed bend-free.

In the event that the at least one first retaining and guiding groove 12a perpendicular to the longitudinal direction or with a component predominantly perpendicular (= transverse) to the longitudinal direction 7 runs, the first holding and guiding groove 12a also bent, with the bending radius is constant. The at least one first jetty 13a is adjusted accordingly to this course.

Preferably, both the at least one first retaining web run 13a as well as the at least one first retaining and guiding groove 12a longitudinal 7 because in particular in the event that parts of the battery module housing 8th or the closure lid 10 are produced in an extrusion process, the first retaining web 13a and the first holding and guiding groove 12a particularly easy to be introduced.

In principle, a production in a plastic injection molding process would also be possible. Also by means of a 3D Printing process could be made a production. This could be the first holding and guiding 12a or the first jetty 13a on too a battery module housing 8th be applied later.

With regard 4B it can be seen that the at least one first retaining web 13a with respect to its cross-sectional shape at least in sections to the cross-sectional shape of the groove receiving area 12a ₁ the at least one first retaining and guiding groove 12a is adjusted. This is achieved in particular by an appropriate choice of suitable cross-sectional shapes of the first holding and guiding 12a and the first jetty 13a ,

In the 4A . 4B and 5A is the first holding and guiding groove 12a formed in cross-section T-shaped, wherein the at least one first retaining web 13a L-shaped and in the corresponding groove receiving area 12a ₁ can intervene. The first jetty 13a could also be T-shaped.

Basically, it would also be possible for the first holding and guiding groove 12a would be L-shaped in cross-section or would approximate such a shape, in which case the first retaining web 13a again would be L-shaped.

In the 5C and 5D other cross-sectional shapes are shown. Basically, the at least one first retaining web comprises 13a an engaging portion 13a ₁ and a guide section 13a ₂ , The engaging section 13a ₁ is in the groove receiving area 12a ₁ arranged, whereas the guide section 13a ₂ preferably predominantly or exclusively in the Nutöffnungsbereich 12a ₂ is arranged. The guide section 13a ₂ of the jetty 13a is with the inside 10a the closure lid 10 connected or formed on this. He could of course also on the battery module housing top 8a of the battery module housing 8th be arranged.

In the 5C and 5D is the groove receiving area 12a ₁ the first holding and guiding groove 12a formed circular in cross-section. The engaging section 13a ₁ of the first jetty 13a is also circular. Basically, an oval training could be possible. It is only important that at least a part of the engagement section 13a ₁ of the jetty 13a on an undercut support area 14 in the groove receiving area 12a ₁ rests.

The first holding and guiding groove 12a has at at least one end an insertion opening (not shown), through the first retaining web 12a with a movement component along the retaining and guiding groove 12a , (in the longitudinal direction of the holding and guiding groove 12a) is insertable. Basically, the holding and guiding could 12a have such an insertion at both ends. It is also possible that an end is closed.

When inserting the first retaining bar 13a in the first holding and guiding groove 12a it is advantageous if a locking device is provided. This locking device should be between the first holding web 13a and the first holding and guiding groove 12a be arranged or in particular between the battery module housing top 8a of the battery module housing 8th and the inside 10a the closure lid 10 , Once the first jetty 13a by a predetermined length in the at least one retaining and guiding groove 12a is inserted, a latching connection is made by the latching device, so that a further displacement in the same or in the opposite direction only with an increased force component is possible for the previous move. The latching device is arranged in particular in the (end) position, which is the first holding web 13a based on the first holding and guiding groove 12a then occupies when the battery module housing 8th with the cap 10 in the battery receiving space 6a should be used. The latching device may comprise a ball catch, wherein a spherical or hemispherical projection engages in a corresponding opening upon reaching the corresponding (end) position.

The at least one first retaining and guiding groove 12a is preferably as long as the at least one first holding web 13a , However, they could also be different lengths, preferably the holding and guiding 12a is longer than the jetty 13a , The holding and guiding groove 12a but could also be shorter than the jetty 13a be, especially if the holding and guiding 12a is open at both ends.

With regard to the cross section in 4A and the enlarged view of area B in FIG 4B is a second holding and guiding groove 12b represented, in which a second holding web 13b intervenes. The arrangement and structure of the second holding and guiding groove 12b corresponds to that of the first holding and guiding groove 12a , The same applies to the second landing stage 13b compared to the first jetty 13a , It should be noted that the at least two retaining and guiding grooves 12a . 12b not both on the battery module housing top 8a or on the inside 10a the closure lid 10 must be arranged, but also separated from each other on the one hand on Akkumodulgehäuse 8th or on the other hand on the closure lid 10 can be arranged. The same applies to the at least two retaining bars 13a . 13b , With regard to the cross-sectional shape, both retaining and guiding grooves 12a . 12b be constructed identically or differently. In the event that the cross-sectional shape of the at least two holding and guiding grooves 12a . 12b differs, the at least two holding webs 13a . 13b only in a particular insertion direction or alignment in the respective holding and guiding grooves 12a . 12b be inserted. This ensures that the cap 10 in the event that it has an asymmetrical structure, always in the correct orientation of the battery receiving space 6a covered.

The at least two holding and guiding grooves 12a . 12b and the at least two holding webs 13a . 13b run parallel to each other.

With regard 4A is shown that the battery module housing 8th non-contact to an inner wall 15 of the at least one frame tube 2 is arranged. The battery module housing 8th is in particular by the cap 10 held. The wording "in particular non-contact" is to be understood as meaning that the battery module housing 8th For example, still on its front sides contact with an inner wall 15 of the frame tube 2 could have. The wording "in particular non-contact" is also to be understood to the effect that electrical connection contacts are included, which on the peripheral wall or on the end sides of the battery module housing 8th are arranged and serve for the transmission of electrical energy to the electric motors, wherein the battery module housing 8th can rest on these electrical connection contacts on electrical connection counter contacts, which on the inner wall 15 of the at least one frame tube 2 are arranged.

In 4A and in the enlargement of the area C 4A in 4C is shown as the cap 10 on the at least one frame tube 2 rests. The cap 10 includes on the inside 10a an at least partially or completely circulating support area 16 , The at least one frame tube 2 also includes an at least partially or completely circumferential support edge 17 passing through the receiving opening 9 is formed. The cap 10 lies over his at least partially or completely circulating support area 16 on the at least partially or completely circumferential support edge 17 of the at least one frame tube 2 on.

Preferably, the at least partially or completely circumferential support area comprises 16 the closure lid 10 a support shoulder 16a , which further preferably comprises a recess, wherein the support edge 17 of the at least one frame tube 2 on this support shoulder 16a or in the recess introduced therein or engages in this. In addition to this support shoulder 16 includes the closure lid 10 preferably still a support tongue 16b , wherein the supporting tongue 16b another edition area 16b ₁ comprises, at least over a certain length of the inner wall 15 of the at least one frame tube 2 touched. The inner wall 15 of the at least one frame tube 2 is therefore at least partially on this further bearing surface 16b ₁ the supporting tongue 16b on. The supporting tongue 16b also extends at least partially or completely along the support area 16 the closure lid 2 ,

The at least partially or completely circulating support area 16 the closure lid 2 includes another seal 18 , this seal 18 between the support area 16 ie between the support shoulder 16a and the at least partially or completely circulating support edge 17 of the at least one frame tube 2 is attached or attached.

The seal 18 is for example fixed to the support shoulder 16b the closure lid 10 arranged and in particular by a 2K spray method or an adhesive method on the support shoulder 16b appropriate. Such a two-component injection molding process is used, although the closure cap 10 made of a plastic.

The seal 18 should be particularly resistant to UV radiation. The seal 18 makes moisture or water difficult between the cap 10 and the frame tube 2 in the battery receiving space 6a can penetrate.

In the 2 . 3A and 3B is still a lock device 20 shown with the at least one frame tube 2 connected is. The lock device 20 is detachable with the accumulator module housing 8th or with the closure lid 10 connected. In a release position of the lock device 20 is the battery module housing 8th together with the cap 10 such in the battery receiving space 6a can be used that the receiving opening 9 through the cap 10 is closed. In the release position, the battery module housing 8th together with the cap 10 also together from the battery receiving space 6a be removed.
