Field of the invention

The invention relates to a bicycle frame with a battery inserted into the frame, which is at least partially covered by a lid. Furthermore, the invention relates to a corresponding, the bicycle frame comprehensive bike, which is designed in particular as an e-bike.

Background of the invention

E-bikes with fully or partially integrated batteries in the frame are known. It is particularly known to insert the battery at least partially into the down tube of the bicycle, the battery being covered by a lid. Such a cover can be adapted in particular to the contour of the down tube, so that it is hardly noticeable that it is an e-bike.

Known from practice lid, also known as "battery cover" are usually connected by means of a screw to the frame and are therefore cumbersome and usually removable only by using a tool.

Object of the invention

The invention is based on the object to provide a bicycle frame, in which a cover which covers a battery can be removed without tools and replaced again. It is a further object of the invention that the lid is securely locked in the attached state and there is no risk of falling out.

Summary of the invention

The invention is achieved by a bicycle frame with a battery according to one of the independent claims and by a bicycle which comprises the bicycle frame.

Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

The invention relates to a bicycle frame with a battery, so a bicycle frame, which is provided for a so-called e-bike.

The battery is at least partially covered by a removable lid.

According to the invention, the lid is releasably secured by means of at least a pressure or a pull closure.

The invention thus provides at least one actuatable by pressing or pulling locking element, by means of which the lid can be easily mounted and removed again.

In particular, a locking element is provided, which is designed such that it automatically locks in a locked state when the cover is placed on. By pressing or pulling an actuator, the lid can be removed easily.

According to a preferred embodiment of the invention, the push or pull closure comprises a connected to the bicycle frame or the lid ball and a push or pullable upper part which is mounted on the lid or bicycle frame and which is lockable on the ball head.

The snapping an upper part on a ball head has the advantage that so position tolerances, especially angle tolerances can be compensated. The ball head can in particular be arranged on a pin inserted into the frame or lid. The pin may for example be screwed or welded to the frame or the lid.

The invention further relates to a bicycle frame with a battery, wherein a removable cover comprises a closure which is designed as a ball coupling. It has been shown that a stable mounting of the lid with a quick coupling is possible even in a small space.

Preferably, closure is designed as the pressure or tension closure. According to another embodiment, the ball coupling is rotatably actuated.

The ball coupling is in particular part of an upper part of the closure.

In particular, a ball coupling is provided, which comprises a cage with openings, from which project in a locked state balls. Via a guide slot, the ball coupling can be brought into an unlocked position into which the wheel balls can deflect radially in order to release the upper part of the ball coupling, in particular in order to release the upper part of the ball coupling from a ball head.

The ball coupling thus comprises a guide slot, which is moved by an axial movement triggered by pressing or pulling or by a rotation in a position in which the balls can escape into at least one recess.

Press-pullable ball couplings are known from other technical fields, such as hydraulic connections.

It has been found that a ball coupling, which preferably consists of metal, is optimally suited to allow a small space, a sufficiently stable locking a battery cover for an e-bike.

The actuator may be formed in the case of embodiment as a pressure closure as a centrally disposed in the housing knob. In the case of a traction coupling, the actuator may for example be formed as a collar comprehensive ring, which can be pulled.

Instead of a ball coupling of the pressure or tension lock is formed in another embodiment of the invention as a snap closure. Such a snap closure may in particular have a bolt with an inclined surface. When closing the latch dodges and snaps in a trap. To release the connection, the bolt can be retracted by a push or pull mechanism.

The lid is particularly attached to the down tube of the frame.

In a preferred embodiment of the invention, the lid is hooked on a side facing the closure, in particular the pressure or pull closure, opposite side into the frame.

Thus, the lid can be attached by exactly one pressure or pull closure. The user only needs to press or pull the trigger and can then fold the lid off and unhook. It is also conceivable to fasten the lid by means of a hinge.

Further, according to another embodiment of the invention, it may also be provided that the cover is fastened by means of a plurality of closures, in particular by means of two pressure or pull closures spaced apart from one another.

The battery is mounted according to an embodiment of the invention in the down tube, but can preferably be removed without tools by the user.

Further, the invention relates to a bicycle frame with a removable battery cover, wherein the battery attached to a lid.

So the user can take out the lid together with the battery.

Preferably, the lid is hooked at the bottom, in particular at the down tube, and fastened at the top with a clip fastener, in particular a quick-release fastener described above.

Preferably, the battery is not electrically connected to a plug, but by means of contacting contacts. Thus, the battery can be removed immediately after the release of the shutter and the electrical connection is made automatically when reinserting the battery.

Detailed description of the drawings

1 is a schematic fragmentary sectional view of a bicycle frame 1 , which can be used for a bicycle, which is designed in particular as e-bike or pedelec.

The bicycle frame 1 includes a down tube 2 , in which a battery 3 for supplying an electric motor with power (not shown) is used. The battery can also be arranged on the top tube or on the seat tube according to another embodiment of the invention.

The battery 3 is covered by a lid 10 in the assembled state.

The lid 10 includes a wall 11 , which is curved and which so the curvature of the down tube 2 adapts.

1 shows the lid 10 in removed condition.

To the lid 10 to take off and put on, includes the bicycle frame 1 a push or pull closure 5 ,

The pressure or pull closure 5 includes a top 10 inserted into the lid 6 with an actuator 7 , which depending on the embodiment of the invention by pressing or pulling the locking of the lid 10 solves.

The top 6 For example, with the wall 11 of the lid 10 screwed, welded, soldered, glued, riveted, or be an integral part of the wall.

To the lid 10 To attach, this is at his the pressure or pull closure 5 opposite end in the down tube 2 hooked (not shown).

The top 6 of the pressure or pull closure 5 gets on a ball head 8th locked.

The ball head 8th is part of one in a wall in this embodiment 4 of the frame used pen 9 , The pencil 9 especially in the wall 4 be screwed in or with the wall 4 be welded.

The top 6 of the pressure or pull closure 5 is preferably designed as a ball coupling, which on the ball head 8th locked. Thus, positional tolerances, in particular with regard to the angle, compensated.

At the same time a secure and stable locking can be provided even with small dimensions by a ball coupling.

Preferably, the diameter of the upper part is 6 less than 30, more preferably less than 20 mm (maximum outer diameter).

2 is a schematic sectional view of a closure, as it can be used for the invention.

In this embodiment, the closure is designed as a pressure closure, which by pressing the actuator 7 can be unlocked.

The actuator 7 is axially displaceable in a housing 12 of the top 6 arranged.

In this embodiment, the actuator is 7 by means of a spring 18 supported. The actuator 7 is thus pressed against spring force.

The feather 18 is in the between actuator 7 and housing 12 existing ring groove 14 used.

Further, the closure comprises a Kugelkä 13 , which in this embodiment of the housing 12 is formed.

The Kugelkä 13 includes openings from which the balls 17 protrude at least in the locked state. It is understood that the openings have a smaller diameter than the balls 17 have, so the balls 17 not from the Kugelkä 13 can fall out.

In the locked state shown here, the balls 17 over the guidance 15 which part of the actuator 7 is held in a position in which they can not dodge radially. As a result, the frame-mounted ball head 8th securely held in the closure.

Now the user presses the actuator 7 against the spring bias, so the recess moves 16 next to the balls 17 so the balls 17 radially in the recess 16 can dodge.

The closure is thus solved in a simple manner by pressing the actuator 7 and the lid dissolves directly with the pressing of the actuator 7 from the frame.

The embodiment of a pressure closure shown here can be constructed particularly flat, since no collar on which the user can pull, is required. In contrast to a pull closure, however, it is again disadvantageous that the actuation direction for releasing the closure thus coincides with the insertion direction of the lid.

The recess 16 may be formed, for example, as an annular groove. It is also conceivable to provide a single pocket as a recess in front of each ball

In another embodiment (not shown), the closure is designed as a pull closure.

In this embodiment, the actuator 7 to be pulled. Otherwise, the embodiment is provided as a ball coupling in the same way. In contrast to the embodiment shown here, the recess is then in the locked state on the opposite side of the balls 7 ,

3 shows one opposite 1 alternative embodiment of the invention, wherein the pressure or pull closure 5 on the frame, here on the down tube 2 is arranged.

In particular, the pressure or pull closure 5 be inserted into an opening of the frame.

Now there is the ball head 8th on the lid 10 , In particular, the ball head 8th with a pen 9 with the lid 10 be connected.

By pressing or pulling the actuator 7 can the lid 10 be solved from above comfortably.

Otherwise, so except for the reverse arrangement, the bicycle frame with the detachable lid 10 corresponding 1 be educated.

4 schematically shows a snap closure 19 how it can be used instead of a ball coupling.

The snap closure 19 can be used for example in the wall of the lid 10 or in a wall of the bicycle frame.

The snap closure 19 includes a spring-loaded latch 20 which when closing the lid 10 behind a trap 21 snaps.

By pressing or pulling an actuator 7 will be the bar 20 pulled back against the spring preload and the lid 10 can be removed or opened.

The invention has succeeded in providing a very easily removable battery cover, which is locked securely at the same time.
