Description

The invention relates to a device with a rocker switch for selecting a drive level of a vehicle, wherein the rocker is positioned at acting on this pressure relative to a base support.

From the DE 10 2011 104 884 A1 are known a device for selecting a driving gear of a vehicle, a steering wheel with such a device and a method for selecting a driving gear of a vehicle. The device comprises a switching rocker, which is pivotable about a fixed axis and depending on a pivoting change in the gear is effected. A spring-biased bolt is coupled to the rocker switch and can be guided along a guide profile depending on a pivoting of the rocker switch. A bolt receiving end portion of the rocker switch has an open first end from which the bolt extends, the end portion comprises a first end opposite the second end, which is connected to a spring-biased and formed separately to the rocker actuator. By the actuator is dependent on its influenced by the movement of the end portion position an electronic switch for driving step change operable.

The invention has for its object to provide a comparison with the prior art improved device with a rocker switch for selecting a gear of a vehicle.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A device with a switching rocker for selecting a driving position of a vehicle is designed such that positions the rocker switch at acting on this pressure relative to a base support. According arranged according to a arranged between the rocker switch and the base support ramp with a spring pin in operative connection, the spring pin slides at a pressure exerted on the rocker switch pressure on the ramp and the spring pin on exceeding a Rampenkuppe a microswitch or switch contact for selecting the gear pressed and a biased spring element between the rocker and the base support the rocker switch is positioned in its initial position, wherein the spring element is also biased in the starting position and pushes the rocker switch from the base support.

In this case, the ramp is arranged for haptic feedback upon actuation of the rocker switch by a user between the rocker switch and the base support. A device designed in this way can be produced at comparatively low costs and with a shorter period of time, the device giving relatively little cause for complaint.

Since the spring element is biased in the starting position of the rocker switch, a game between rocker and base support is significantly reduced, causing a tilting of the rocker switch and an associated unwanted noise can be largely eliminated. Thus, especially on a so-called Schlechtwegestrecke no unwanted noise is heard.

Embodiments of the invention are explained in more detail below with reference to drawings.

• 2 schematically a sectional view of a second embodiment of the device with a rocker switch and
• 3 schematically a sectional view of an enlarged section of the second embodiment of the device with a switching rocker.

Corresponding parts are provided in all figures with the same reference numerals.

1 shows a sectional view of a first embodiment of a device 1 with a rocker switch 2 and a basic carrier 3 to which the rocker switch 2 is relatively positionable.

At cost and a manufacturing time of the device 1 while retaining haptic feedback to a user of the device 1 is a device described below 1 with the rocker switch 2 , in particular for the selection of a drive level of a vehicle not shown in detail, provided.

In the first embodiment, the device comprises 1 around a pivot axis S pivotable on the base support 3 arranged rocker switch 2 and the basic carrier 3 itself, on which a microswitch 4 with a movable spring pin 5 is attached. Alternatively, instead of the microswitch 4 another suitable switching contact can be used.

The rocker switch 2 is at least in sections of the basic carrier 3 surrounded by the rocker switch 2 their pivotal movement relative to the base support 3 executes, wherein the pivoting movement is limited by means of a stop. This is on an outer surface of the rocker switch 2 a pen 6 formed, which in a recess A is guided to limit the pivoting movement. Will a pressure on the rocker switch 2 exercised, this can be up to a lower limit of the recess A to be moved. In addition, between the rocker switch 2 and the basic carrier 3 a spring element 7 , In particular a compression spring in the form of a coil spring or leg spring, arranged, the spring axis perpendicular to the longitudinal axis of the spring pin 5 runs.

On an inner surface of the rocker switch 2 is a ramp R formed with the spring pin 5 is in active connection. Through on the rocker switch 2 applied pressure, against a spring force of the spring element 7 moves the spring pin 5 along the ramp R , wherein after crossing a Rampenkuppe K an electrical switching contact between the spring pin 5 and the microswitch 4 , in particular for selecting a driving position of the vehicle is made. The crossing of the Rampenkuppe K , which is perceived by a user as a jump, provides a haptic feedback to the user of the device 1 represents.

The rocker switch 2 is after crossing the Rampenkuppe K by a predetermined pivoting of, for example, 1.5 mm in the direction of the base support 3 positionable, wherein the pivoting movement through the lower boundary of the recess A is limited. By the movement of the rocker switch 2 in the direction of the basic carrier 3 increases the bias of the spring element 7 , so that when pressure is exerted on the rocker switch 2 this can be positioned in its initial position. Here is a pivoting movement of the rocker switch 2 from the basic carrier 3 away through an upper boundary of the recess A , in which the on the rocker switch 2 trained pen 6 is guided, limited. The spring element 7 points in the starting position of the rocker switch 2 relative to the basic carrier 3 a bias on, leaving the rocker switch 2 from the basic carrier 3 is wegdrückbar, thus a game between rocker switch 2 and basic carrier 3 can be largely excluded and thereby undesirable noise during driving the vehicle can be counteracted.

In the in 2 shown second embodiment of the device 1 is the spring element 7 compared to the first embodiment in the immediate vicinity, so in a minimum possible distance to the pivot axis S the rocker switch 2 arranged.

By the arrangement of the spring element 7 which is formed as in the first embodiment as a screw or leg spring, in the immediate vicinity of the pivot axis S is the pivot axis S against storage L at the base carrier 3 pressed, leaving a game between the rocker switch 2 and the basic carrier 3 is largely reduced. It is in 3 an enlarged section of the storage L shown.

The rocker switch 2 is opposite the basic carrier 3 not tiltable, so that unwanted noise, so a rattle, can be largely excluded. Even with comparatively low pressure on the rocker switch 2 to cause rattling is in the second embodiment of the device 1 essentially not possible. Does the vehicle a so-called Schlechtwegestrecke is in the device 1 at least in the second embodiment largely excluded that a rattling noise can be heard.
