Description

The invention relates to a vehicle, in particular a vehicle which can be driven electrically and / or by muscular force, comprising a frame, at least two wheels, a steering device and a seat for transporting a passenger and / or a load receiver for transporting piece goods, the frame being designed in this way in that it allows the intended guidance of the vehicle by a vehicle driver while standing.

From the prior art are electrically and / or driven by muscle power vehicles known. These include, for example, bicycles, e-bikes, e-scooters, e-scooters, electric wheelchairs or electric vehicles.

All of the aforementioned vehicles are only partially suitable for the transport of general cargo and / or persons. In addition, the handling of such vehicles for the driver during transport is only partially satisfactory. In particular, in the case of single-lane vehicles for passengers on the one hand and the driver on the other hand, it is comparatively difficult to get on the vehicle or to get off the vehicle. Even in the case of two-lane vehicles, this is sometimes difficult, in particular in the area of light vehicles, due to the limited space available.

In addition, in the area of transportation of passengers with reduced mobility, special demands are placed on handling and ease of use. Movements that are easily possible for normal mobile people, are sometimes impossible to accomplish for mobile restricted people.

In this context, it is not just about the comfortable position during transport. On the contrary, the necessary conditions for people's access to the promotion position must already be created.

In this regard, the known from the prior art vehicles are insufficient. There is therefore a vital economic interest in vehicles for comparatively short distances within the hospital or airport area for the transport of persons and / or general cargo, such as luggage, consumer goods or food.

It has also been found in this regard that the previously available vehicles have disadvantages in handling, especially when entering and exiting and braking. The steering systems used in the prior art lead in these states undesirably to a destabilization of the vehicle situation.

The invention is therefore based on the object to provide a vehicle in which the disadvantages known from the prior art are avoided.

To solve the problem, the invention proposes a generic vehicle, which is characterized by a tilting technique, which is user-activated and / or deactivated.

The embodiment according to the invention makes it possible for the driver of the vehicle, on the one hand, to ascend the vehicle comparatively quickly and easily and to descend therefrom. Furthermore, the overview of the driver is decisively improved by the intended guidance of the vehicle. Dangerous situations can be detected in good time and avoided. Further, in the case of providing a seat for carrying a passenger over the space otherwise provided for the driver, barrier-free access can be achieved. Overall, on the one hand the handling of the vehicle for the driver is facilitated and on the other hand improves the access to the transport position for especially limited in their mobility people.

According to a feature of the invention, in particular in the case of two-lane vehicles, a tilting technique is provided. The tilting technology supports the user-side steering movement by inclination of the vehicle. This can be achieved in that a rear vehicle part carrying a rear wheel is arranged such that it can rotate about a common longitudinal axis relative to a front vehicle part carrying a front wheel. The tilting technique can be switched off (deactivatable) and / or switched on (can be activated). According to a feature of the invention, it is provided that it can be manually operated, in particular activated and / or deactivated. This makes it possible in particular to deactivate the tilting technology in the state when the user has not yet mounted the vehicle. This prevents the vehicle from inclining towards the user during ascent, which advantageously facilitates the ascent to the vehicle. Preferably, the vehicle has a manually operable switch.

Preferably, the switch is designed as a footboard. Preferably, the footboard between two positions is movable, in particular pivotable. For this purpose, the footboard is preferably pivotally hinged to the frame. The tilting technique is activated in a first position and deactivated in a second position. It is preferably provided that the user operates the footboard with his foot. It is the footboard means Weight shift between the two positions moves, in particular pivoted. If a user wants to deactivate the tilting technique when getting on the vehicle, he first steps onto the running board with one foot. Preferably, the tilting technique is disabled when the user transfers the footboard to the second position. This is preferably done when the footboard is pivoted toward the front wheel. It has been found that a user usually first places the ball of the foot on the running board when climbing onto the vehicle. As a result, the deactivation of the inclination technique during the ascent is simplified in an advantageous manner. If the user wants to activate the tilting technique, he loads the footboard with his heel to move the footboard in the first position, in particular to pivot.

Alternatively or preferably, the switch is integrated in one of the brake levers, preferably in the rear brake lever. Functionally, the integration can be configured in such a way that actuation of the brake simultaneously effects the deactivation of the tilting technique. This causes, during the ride, a stabilization of the vehicle in case of braking. A release of the brake lever preferably leads to an automatic reactivation of the tilting technique. In the particular embodiment with running board and integrated in the brake lever switch, it is preferred if a release of the brake lever does not automatically lead to a reactivation of the tilting technique. Instead, the tilting technique can be activated by means of the footboard on manual input. In contrast, in the embodiment in which the footboard forms the sole switch, a functional separation of the brake and the inclination technology is achieved. In certain traffic situations, this may also be beneficial for security reasons.

In addition to the user-side operability, the tilting technology can preferably be designed to be able to be switched off and switched on automatically in accordance with predefinable parameters, in particular the speed. In particular, it is provided that the tilting technology is designed to be automatically controllable as a function of the speed of the vehicle. For safety reasons, it is advantageous to deactivate the tilting technology at comparatively high speeds. In contrast, to improve the steering characteristics, it is advantageous to activate the tilting technology at comparatively low speeds.

The tilting technique is present manually switched on and off. For this serves the footboard 37 , As a result, it is possible, in particular, to deactivate the tilting technology when the user is standing by the electrotransport vehicle 1 has not climbed yet. This will prevent the electrotransport vehicle 1 Ascending the user in the ascent, which in an advantageous way the rise on the electrotransport vehicle 1 facilitated.

The footboard 37 is present pivotable between two positions. This is the footboard 37 swiveling on the intermediate part 4 hinged. The tilting technique is activated in a first position and deactivated in a second position. It is envisaged that the user will use the footboard 37 operated with his foot. This is the footboard 37 pivoted by weight shift between the two positions. Would a user like the tilt technique when getting on the electrotransport vehicle 1 he steps on the footboard first with one foot 37 , The tilting technology is deactivated when the user uses the footboard 37 transferred to the second position. This happens when the footboard 37 in the direction of the front wheel 7b is pivoted.

It has been shown that a user while climbing on the electrotransport vehicle 1 Usually the ball of foot first on the running board 37 touches down. As a result, the deactivation of the inclination technique during the ascent is simplified in an advantageous manner.

If the user wants to activate the tilting technique, he will load the running board 37 with his heel to the running board 37 in the first position towards the rear wheel 7a to pivot.

Alternatively or additionally, the tilting technique by means of the rear brake lever 12a be deactivated. An actuation of the brake lever 12a at the same time causes the activation of the rear wheel brake 16 and the shutdown of the tilting technique. This causes stabilization of the electric transport vehicle while driving 1 in case of braking. A release of the brake lever 12a Preferably, this does not lead to an automatic reactivation of the tilting technique. Instead, the tilting technique by means of the footboard 37 be reactivated on manual input.

Furthermore, in 11 the connecting bridge 38 with his eyelet 36 and its recess 39 to recognize.
