description

The invention relates to a handlebar for a vehicle according to claim 1. Furthermore, the invention relates to a vehicle according to claim 12.

Motor scooters equipped with electric drives are known, for example, from EP 1 857 314 A2. Corresponding electric scooter or

Motorized two-wheelers usually have a body and two wheels, wherein one of the wheels is driven by an electric drive. Furthermore, such scooters usually have a handlebar assembly comprising a handlebar with a base and a display unit for the representation of

Speed information or the state of charge of a battery. In addition, two handles are attached to the handlebar, through which the driver can control the vehicle.

Furthermore, scooters are known which can be folded together for easy transportation or storage. In this case, a small pack size of the folded scooter and a compact form are important. Overhanging components make it more difficult to handle the folded scooter.

Based on this prior art, it is an object of the present invention to provide a handlebar or a vehicle, which contributes to achieve a small pack size when folding the scooter.

According to the invention, this object is achieved by the objects of

Claims 1 and 12 solved.

Advantageous and expedient embodiments of the handlebar or the vehicle according to the invention are specified in the subclaims.

In particular, the problem is solved by a handlebar with a base. It may be in the handlebar to a handlebar for a vehicle such. B. one Electric scooter, a motorcycle or an electrically powered quad, act. The handlebar can also for other non-electrically powered vehicles, such. As a bicycle, be provided.

The handlebar with the base comprises at least one handle carrier (with a

Handle), which is articulated to the base and which is pivotable from a first carrier position to a second carrier position. Furthermore, the handlebar comprises a holding device, which is arranged or formed such that it articulates from a first holding position to a second holding position

is pivotable. The holding device locks in the first

Hold the handlebar with the base. The handlebar further comprises a locking device which is pivotally mounted on the base and which is pivotable from a first locking position to a second locking position, wherein the locking device is arranged or formed such that the

Locking device in the first locking position blocks the holding device.

The handlebar can therefore as part of the folding process of a vehicle

be folded, resulting in a compact pack size. The handlebar comprises a base, which is preferably fixedly connected to a steering column of the handlebar and at least one handle carrier, a holding device and a locking device. The handle carrier can in one embodiment, for. B.

Have brake handles or a throttle. To an accidental

To prevent collapse of the handlebar, the locking device blocks the holding device, so that the at least one handle carrier can not be pivoted when the individual components are in the corresponding positions. It is provided that, during operation of the vehicle, the at least one handle carrier in the first carrier position, the

Holding device in the first holding position and the locking device are in the first locking position. It is thus prevented that the handle supports are pivoted during operation, since they are held by the holding device, which in turn is secured by the locking device. This increases safety while driving.

However, if the vehicle is not in operation and is to be folded, by pivoting the locking device the

Retaining device can be unlocked so that the holding device can be pivoted into the second holding position. Then the at least one Handle carrier to be pivoted in the second carrier position. This allows a very simple folding of the handlebar by means of fewer handles and can be carried out by a person.

In one embodiment, the at least one handle carrier in the first holding position, at least partially positive or frictionally engaged in the

Holding device are held.

If the at least one handle carrier is held in the first holding position at least partially positively in the holding device, so is

ensures that this does not deform under load, so that a high stability is ensured.

Furthermore, in one embodiment, the holding device can be rotatably mounted on the base via a holding joint about a holding device rotation axis.

Although the holding device is arranged on the base via a holding joint, the holding joint is an integral part of the base. It is thus ensured increased stability of the overall construction. In particular, the stability is increased when the holding device locks the at least one handle carrier, because when the driver exerts pressure on the at least one handle carrier, high

Torque acting on the support joint and corresponding forces are transmitted to the base.

In one embodiment, the holding device may be biased by a spring element in the first holding position.

So that the at least one handle support can not be accidentally released, the holding device can be biased by a spring element in the first holding position. This leads to increased security. In addition, it is more comfortable for the driver to operate the holding device, if this when pivoting the handle carrier in the horizontal due to the spring

snaps.

In one embodiment, a recess of the holding device may be formed corresponding to a pin of the at least one handle carrier. To the lock between the at least one handle carrier and the

To realize holding device, an interaction of a pin of the at least one handle carrier may be provided with a recess of the holding device. If the recess is formed corresponding to the pin, then a particularly good fit of the pin in the

Recess ensured. This again leads to increased stability. In the described embodiment, however, the security is increased because a casual release of the lock is prevented.

In one embodiment, the pin and the recess may be arranged and / or formed such that the pin engages in the recess in the first holding position for locking.

In one embodiment, the pin of the at least one handle carrier may be inclined at an angle from the longitudinal axis of the at least one handle carrier.

If the pin is disposed at an angle inclined to the longitudinal axis of the at least one handle carrier, then a further improved locking is achieved because the lock is stable and can be solved very easily.

In one embodiment, at least one contact surface of the recess may be at least partially formed following a first radius about the holder rotation axis. The at least one boundary surface of the pin may, in one embodiment, be formed in the first carrier position at least partially following a second radius around the holder rotation axis. The recess and the pin can thereby in one

Embodiment be formed substantially complementary.

When the contact surface of the recess has a substantially round shape and the boundary surface of the pin substantially

is formed corresponding to the contact surface, then the

Bearing surface large. This means that a material-sparing application of force is provided.

Furthermore, the holder in an insertion direction, for. B. substantially transverse to the holding device axis of rotation, be formed in a tapered shape. In an embodiment in which the recess may be formed in a direction of insertion with a tapered shape, a gap is formed between the pin and the contact surface of the recess. This offers great advantages. If it comes by friction or shock to wear on the pin, the pin can get into deeper and deeper into the recess. In particular, in combination with a prestressed holder, the pin is pulled by a spring force into the recess. It is thus ensured a particularly firm and long grip when it comes to wear on the pin.

In a further embodiment, the locking device may comprise a rotatably mounted locking disk or parts of a locking disk, preferably on a shaft.

If the locking device comprises a rotatably mounted locking disc, a particularly simple construction of the locking device is given. In this case, the locking disk may be formed so that it has a non-rotationally symmetrical shape. In particular, in one embodiment, the blocking disk may be designed such that it is reinforced in a blocking region. Thus, on the one hand, the blocking of the holding device can be improved, on the other hand this again increases the service life, since in this embodiment there is an increased material strength in the region of the greatest loads.

In one embodiment, a display unit with off and / or

Input function to be hinged to the base, wherein the display unit may include a cover which prevents in one position actuation of an operating lever of the holding device.

To prevent misuse, an operating lever of

Holding device from the driver's access during operation of the driver

Motor scooter be protected. The operation of the scooter can be displayed by an unfolded position of the display unit. The display unit can, for. B. include a speedometer, and specify the state of charge of a battery. The display unit may be an ordinary display, e.g. As an LCD or OLED screen, act or even a touch screen, such as a capacitive or resistive touchscreen. So pure output devices are just as possible as combined output and input devices. In a further embodiment, the display unit can be rotatably mounted on the shaft about a display axis of rotation, wherein the display unit can be operatively connected to the locking device via the shaft for pivoting the locking device from the first locking position to the second locking position.

It is therefore possible that the locking device is simultaneously pivoted by the pivoting of the display unit. The pivoting of the display unit can thus block the holding device by the

Release locking device. In the folded-down state of the display unit, it is possible to pivot the at least one handle carrier. Such a

Design leads to a very simple folding mechanism, since the driver only has to make two handles in order to pivot the at least one handle support. This can be done with one hand.

In another embodiment, the handlebar may include a spring member that may be configured to bias the display unit in a direction toward an unfolded position.

If a spring element biases the display unit in the direction of the unfolded position, an inadvertent pivoting of the display unit during driving is prevented. The described embodiment thus once again increases the safety of the driver.

In one embodiment, the link may comprise a latching element, in particular spring-loaded balls, which may be designed and / or arranged to latch the display unit in the unfolded position.

Alternatively or in addition to the spring element, the display unit can be locked by a locking element in the unfolded position. So it is necessary more force to release the display unit from the unfolded position or it is necessary to solve the locking otherwise.

In one embodiment, the handlebar may comprise a housing, wherein the housing may be arranged and / or formed by a

unfolded position to be pivoted into a folded position, wherein the housing in the unfolded position can block the operating lever. If the handlebar includes a housing that can accommodate, for example, the display unit, then another safety mechanism can be provided in which the housing in an unfolded position prevents actuation of the operating lever.

The object is further achieved by a vehicle comprising:

a handlebar as described above;

- At least one drive unit;

- At least one sensor unit which is adapted to detect the position of the display unit and / or the housing and / or the locking device;

a supply device for supplying the at least one

Drive unit with energy;

a communicatively connected to the at least one sensor unit

Control device for controlling the power supply of the at least one drive unit by the supply device, wherein the control device is adapted to interrupt the power supply of the at least one drive unit when the at least one sensor unit detects that the display unit and / or the

Locking device and / or the housing in the first locking position or

folded position or are located.

With regard to the handlebar of the vehicle, similar or identical advantages result, as have already been presented in connection with the handlebar described above.

The display unit or the locking device or the housing can be used to interrupt the power supply of a drive unit of a vehicle. The security is thus increased again, if the

Display unit, the locking device and / or the housing as a kind

Ignition key can be used.

In one embodiment, the at least one sensor unit as an electrical switch, a rangefinder, a brightness sensor or a mechanical switch such. B. a magnetic sensor or button. The at least one sensor unit can be configured by different components. Of course, a combination of different components is conceivable to z. B. to compensate for the failure of a device.

In the following description, the same reference numerals are used for identical and equivalent parts.

1 to 3 show an electrically driven scooter 10 with two wheels 11, 1 and a handlebar 21 in a first embodiment. The scooter 10 shown in FIGS. 1 to 3 is a foldable scooter 10. The scooter 10 further includes a drive unit 12, which in the first

Embodiment is designed as an electric motor. The handlebar 21 is fixedly mounted on a steering column 20 which can be pivoted about a pivot axis S and the handlebar 21 comprises a base 22 and handles 14. Die

Handles 14 are arranged on handle supports 30, 30 'on the base 22. About the handles 14, the driver of the scooter 10 can control various functions of the scooter 10, such. As horns, flashing, brake or accelerate. The handle supports 30, 30 'are mutually hingedly connected to the base 22. In the front region of the scooter 10 is on the handlebar 21 a

Operation opening 13 is provided, in which a driver can reach into and which can be used to pull the scooter 10, if this

folded up.

The driver can reach an actuating lever 56 by grasping through the actuating opening 13 and release a locking of the handles 14 and thus fold the handlebar 21 together. This is in a second

Embodiment unlocking the handles 14 in the unfolded state of the display unit 23 prevents. This will be explained in detail in connection with FIGS. 10 and 11.

Fig. 4 is a detail view of important mechanical parts of the handlebar 21 of the first embodiment, wherein trim parts and the base 22 are not shown to illustrate the operation of the lock. Fig. 4 shows a display unit 23 in the unfolded position, wherein in the first embodiment, a locking device 40 is arranged laterally on the display unit 23. The display unit 23 and the locking device 40 are both rotatably mounted on a shaft about the display axis of rotation B. The display unit 23 and the blocking device 40 can thus only in the first embodiment be pivoted together. Furthermore, FIG. 4 shows two handle supports 30, 30, which are each arranged laterally below the display unit 23. The

Handle carriers 30, 30 'are rotatably connected to carrier joints 31 pivotally connected to the base 22. The handle carriers 30, 30 'are locked by a holding device 50. The holding device 50 is pivotally connected to the base 22 via a holding joint 51. The handle beams 30, 30 'may be made of a variety of materials and in a variety of configurations. In the first embodiment, the handle supports 30, 30 'are made as hollow tubes

Fiber composite formed. In further embodiments, the

Handle carrier 30, 30 'z. B. formed as a hollow aluminum or magnesium tubes.

Preferably lightweight materials are used to reduce the weight and so positively on the power consumption of the scooter 10th

act.

Fig. 5 shows parts of the arm 21 of Fig. 4 in a schematic front view. In particular, FIG. 5 shows that the holding device 50 can be pivoted via actuating lever 56. In this case, the operating lever 56 those

Elements that the driver must operate to collapse the handlebar 21. However, as clearly shown in Figs. 4 and 5, an operation of the operating lever 56 by the driver while the display unit 23 is in an unfolded position is not possible. In the aforementioned case, the locking device 40 blocks locking levers 41, which are connected to the holding device 50.

FIGS. 6 and 7 show, in a detailed representation, how the interlocking device 40, the holding device 50 and the handle carriers 30, 30 'prevent the handle carriers 30, 30' from being folded down. In the embodiment shown in Figs. 6 and 7, the locking device 40 is as a

Locking disk formed. The locking disc is not rotationally symmetrical in the first embodiment, but has an area which has a projection. The region of the projection is reinforced in order to take account of increased load on the projection. As

In particular, as shown in Fig. 7, the locking disc 40 blocks a

Pivoting of the locking lever 41 and thus pivoting the

Holding device 50. In order to ensure a secure hold of the holding device 50, this is biased by a spring. In the first embodiment, the spring biases the holding device 50 so that the locking of the handle support 30, 30 'is ensured, ie in the direction of the locking position of

Holding device 50. In this case, the spring is arranged on the holder device 50 in a region between the holding joint 51 and the carrier joint 31 and on the base 22 in a region between the holding joint 51 and the carrier joint 31. The spring causes the handle carriers 30, 30 'to snap into the holding device 50 when unfolding or folding upwards.

The interaction of the locking device 40 with the holding device 50 also leads to an accidental folding down of the handle support 30, 30 'is not possible. Further, characterized in that the display unit 23 with the

Locking device 40 is operatively connected, ensures that folding down the handle support 30, 30 'in an unfolded position of the display unit 23 is not possible. It is therefore not possible for a driver during operation of the scooter 10, the handle support 30, 30 'fold down.

8 and 9 show the locking device 40, the holding device 50 and the handle support 30, 30 'in a locked position and a folded-down position.

In the embodiment shown in FIG. 8, the handle carrier 30, 30 'is designed such that at its end toward the holding device 50, a pin 42 engages in a recess 52 of the holding device 50. The shown

Embodiment offers particular advantages in terms of wear of the materials, as will be explained in detail below.

The recess 52 of the holding device 50 is formed so that a

Contact surface 55 at least partially along a circle with a radius Rl to a holding joint 51 follows. The pin 42 of the handle support 30, 30 'is in

Substantially complementary to the recess 52 is formed. The pin 42 is in the locked position thus uniformly and over a large area with a boundary surface 53 on the contact surface 55.

The recess 52 is also substantially tapered, with the degree of taper in the rear of the recess 52 decreasing. By doing illustrated embodiment, the pin 42 is also tapered

formed, however, the degree of taper is less than that of the recess 52. As shown in Fig. 8, thereby arises in the locked state a

Cavity 54 between pin 42 and the holding device 50. The pin 42 is clamped at its upper and lower boundary surfaces 53 of the holder 50 and has no play.

During use of the handlebar 21 by a driver, it comes due to an induced torque M to increased stress in a wear area 43 on the pin 42 and the holding device 50. After prolonged use, it can come in wear in the area 43 in particular wear and the Handle carrier 30, 30 could sit loose after wear. Characterized in that the holding device 50 by a

However spring element is biased, the pin 42 is pulled deeper into the recess 52, wherein the cavity 54 is smaller. Thus, even during a continuous load, in which it comes to wear, an optimal fit of the handle support 30, 30 'guaranteed. Thus, that a cavity 54 is provided between the holding device 50 and the pin 42, the life of the link 21 is extended. Furthermore, a non-fixed handlebar is a major security risk.

Further, Fig. 8 shows that the pin 42 is formed at an obtuse angle from the longitudinal axis of the handle support 30, 30 'running away. The

Holding device 50 engages not only laterally in the pin 42, but slightly from above. Under load of the handle support 30, 30 ', therefore, the pin 42 presses into the recess 52, that the pin 42 is pressed into the recess 52 into it.

Fig. 9 illustrates the locking device 40 in a non-blocking position. In the illustrated position, the actuating lever 56 of the

Holding device 50 are actuated, and the holding device 50 can be pivoted from a locked to an unlocked position. Subsequently, the handle support 30, 30 'are folded down.

FIGS. 10 and 11 show a further advantage of the described link 21. FIG. 10 is a schematic sectional view of the link 21 through the link

Display unit 23, wherein the display unit 23 and the holding device 50 are shown. Fig. 10 shows the display unit 23 in an unfolded position. In the illustrated unfolded position of the display unit 23, the display unit 23 blocks the operating lever 56 of the holding device 50. The driver of the scooter 10 can thus not pivot the holding device 50.

Fig. 11 shows the display unit 23 in a folded-down position. As is apparent from Fig. 11, the operating lever 56 can now through the

Actuating opening 13 are actuated and the holding device 50 are pivoted about the support joint 51.

In the illustrated embodiment, a blocking surface 25 is formed substantially flat in the unfolded position and be arranged below a display axis of rotation B. The display rotation axis B of the display unit 23 is in the illustrated embodiment to a front side 24 of the display unit 23 offset from a central axis A of the display unit 23, wherein the central axis A in from an upper to a lower end of

Display unit 23 runs. Furthermore, the operating lever 56 of the

Holding device 50 is arranged so that the blocking surface 25 of the display unit 23 prevents pivoting of the holding device 50 in the unfolded position of the display unit 23.

In one exemplary embodiment, closing the display unit 23 can also interrupt the power supply of the drive unit 12. The folding of the display unit 23 leads to the actuation of a switch which is arranged between the display unit 23 and the underlying control panel. The switch, when actuated, sends a signal to a controller, which in response interrupts the flow of current from a battery to the drive unit 12.

It should be noted at this point that all parts described above, taken alone and in any combination, especially in the
