Storage compartment for a motor vehicle

The invention relates to a storage compartment for a motor vehicle, with a tub-shaped

Housing part, which has an opening, and with a closing element, which is arranged displaceably between an open position and a closed position for releasing and closing the opening on the housing part, with a lighting device, which has at least one controllable illuminant, which is designed and / or arranged for this purpose is to shine at least substantially into the housing part, and with a

Sensor device for detecting a displacement position of the closing element, wherein the

Lighting device is designed to control the lighting means as a function of the detected displacement position.

Storage compartments of the type mentioned are already known from the prior art. For example, the published patent application DE 10 2014 222 954 A1 discloses a center console storage compartment with the features of the preamble of claim 1. The storage compartment has a tub-shaped housing part with an opening that can be closed and released by a roller blind as a closing element. The roller blind can be used in a compression device

inserted and rolled up there. There is a

Arranged sensor device that detects a stowed state of the roller blind, wherein in

Depending on the stowed position of the roller blind, which corresponds to the closed position of the roller blind over the opening, a lighting device is activated in order to illuminate the interior of the housing part when the roller blind is stowed in the compression device.

Furthermore, from the published patent application DE 10 2012 024 667 A1, a lighting device for a storage compartment is known which has an optical light guide which is separated or connected depending on a closed position of a closing element. Furthermore, the laid-open specification DE 10 2012 017 597 A1 describes a lighting device for a

Storage compartment known, which also has a light guide, which produces or interrupts a light guide depending on a displacement position of a closing element. From the patent application DE 10 2007 017 477 A1 is a storage compartment with a

Lighting device known, wherein the storage compartment is free of closing elements.

The invention is based on the object of creating an improved storage compartment for a motor vehicle which, in particular, is easy to use and can be implemented cost-effectively. The object on which the invention is based is achieved by a storage compartment having the features of claim 1. This is characterized by the fact that the closing element

arranged pivotably on the housing part and the sensor device is designed to work without contact. Characterized in that the closing element is pivotable on the

Housing part is arranged, a simpler folding mechanism for pivoting the closing element is sufficient, whereby an inexpensive implementation of the storage compartment itself is guaranteed. In connection with the present invention, a storage compartment is understood to mean both a center console storage compartment, as has already been described above, and a glove compartment, dashboard compartment or a trunk of a motor vehicle.

The sensor device preferably has at least one inclination sensor which is arranged on the closing element. This is the shift position of the closing element in

Determined depending on their inclination by means of the inclination sensor. As a result, a further element of the sensor device on the stationary part of the storage compartment is not necessary in order to detect the displacement position of the closing element. As a result, the storage compartment can be displayed in a particularly compact manner. The inclination sensor is preferably designed to detect the absolute inclination with respect to a horizontal. Alternatively, the inclination sensor only detects a change in inclination. The inclination sensor is preferred as a mechanical one

Inclination switch or as an intelligently evaluated sensor, in particular a gyro sensor. At least in the latter case, the inclination sensor is preferably one

Evaluation unit, which has a microprocessor, for example, assigned to evaluate the sensor data of the gyro sensor. The evaluation unit is preferably arranged together with the associated inclination sensor on a common carrier substrate, in particular a common printed circuit board, on which the lighting device is preferably also arranged.

The lighting device and / or the inclination sensor are preferably calibrated in such a way that the lighting means is activated in the open position of the closing element and in the

Closed position is deactivated. Knowing the expected inclination of the

The inclination sensor in the open position as well as in the closed position ensures simple control of the lighting device. For this purpose, the expected angle of inclination in the open position and in the closed position are preferably stored in a non-volatile memory in order to control the lighting element by a simple comparison with the currently recorded angle of inclination. Preferably are the expected ones

Angles of inclination in the open position and in the closed position Assigned tolerance range within which a control or activation or

Deactivation of the lighting means takes place, the tolerance range covering, for example, 1 5.

According to a preferred development of the invention, the closing element is mounted such that it can be pivoted through a pivot angle of more than 30 °, in particular 42 ° or more than 42 °. By providing a swivel angle which is more than 30 °, it is taken into account that usually public roads do not or only rarely exceed an incline angle of 15 ° (+/-). If higher pitch angles are expected, the swivel angle can

adjusted accordingly. The advantageous choice of the pivot angle has the consequence that the closing element can be pivoted through a pivot angle which is greater than a maximum change in gradient of a roadway along which the storage compartment is located

having motor vehicle is moved. This has the consequence that the closing element cannot be changed in its orientation by a change in the road gradient beyond the specified pivot angle. As a result, a movement of the closing element that is caused by a user can be reliably distinguished from one

Guaranteed change in the incline of the lane, so that incorrect control of the illuminant by the lighting device is simply prevented. Thus, for example, the lighting means is only controlled or switched, that is to say switched on or off, when the closing element has been displaced over the entire pivot angle.

According to a preferred development of the invention, the lighting device and / or inclination sensor are calibrated in such a way that the lighting means is only switched when a predeterminable switching angle that lies between the open position and the closed position is exceeded. A switching angle is thus selected as the triggering threshold for the activation of the lighting means, which is between the open position and the closed position, in particular at least essentially in the middle between them. As a result, the lamp is already switched on when the closing element has not yet been fully moved into the open position, or switched off when the closing element has not yet been fully moved into the open position

Closed position was moved. This simplifies the convenience of using the storage compartment for one person because the light source is switched on or at an early stage

is switched off.

The switching angle is particularly preferably 5 ° to 10 ° below a horizontal alignment. The horizontal alignment, which can be easily detected by the inclination sensor, is to this extent a reference alignment from which the switching angle is determined.

According to a preferred further development of the invention, in the closed position the closing element has a section which is pivotably mounted at one end on the housing part and at the other end an end portion oriented inclined thereto, the inclination sensor being arranged on the end portion. The inclination sensor is thus arranged far away from the pivot axis of the section on the housing part, so that there is a lever arm that is as large as possible, which ensures that the inclination sensor reliably detects the change in inclination or at inclination points. In particular, when the storage compartment is properly installed in the motor vehicle, the end section is oriented inclined such that it is oriented inclined to the horizontal in the open position and in the closed position, and the horizontal on the way from the

Passes open position to closed position. This ensures an advantageous detection of a movement of the closing element into the open position because a zero crossing (negative angle of inclination to positive angle of inclination) can be detected when the

Closing element from the open to the closed position, respectively

is moved the other way around. If the inclination sensor is designed as a mechanical inclination switch, it can be implemented cost-effectively "without intelligence". Through an optimized

However, as already described above, the alignment and arrangement of the sensor on the closing element ensures reliable use for lighting actuation. If the inclination sensor is designed as an intelligent sensor, in particular as a gyro sensor, its alignment and arrangement on the closing element is more flexible. Such intelligent inclination sensors are now widespread in cellular telephones or mobile computers and are therefore inexpensive, so that an inexpensive implementation of the storage compartment is guaranteed even when using an intelligent sensor. Angular parameters

or corrections, can then be adjusted or optimized using a software program.

According to a further embodiment of the invention, the sensor device has at least one Hall sensor, a reed contact, a capacitive sensor and / or an optical sensor in order to detect a displacement position of the closing element. In particular, the last-mentioned embodiment of the sensor device ensures that it is possible to detect whether the closing element is in the closed position or not. A

Understanding of the swivel angle is omitted or can be omitted. This embodiment allows inexpensive and simple determination of whether the closing element is in the

Closed position. The lighting device is designed so that when it is detected by means of the described sensor device that the

Closing element is in the closed position, the lamp is deactivated. This embodiment is preferably provided in addition or as an alternative to the presence of the inclination sensor. If this embodiment is also present, it is used in particular to check / verify the plausibility of the data from the inclination sensor. Is it available as an alternative to the inclination sensor, so that for example not one continuous detection of the swivel angle position of the closing element can be detected, but only whether the closing element is in the closed position or not.

This enables a simplified evaluation and control of the lighting device.

Furthermore, it is preferably provided that the one described in the previous paragraph

Sensor device has a signal receiver and a signal transmitter, the

Signal receiver is arranged on the closing element or on the storage compartment and the signal transmitter on the storage compartment or on the closing element, and wherein the

Lighting device is designed to deactivate lighting means when the presence of the signal transmitter is detected by the signal receiver. This embodiment is particularly advantageous when designing the sensor device with a Hall sensor, reed contact, capacitive sensor and / or optical sensor because these are designed in two parts and each have a signal receiver (for example magnetic field sensor or optical sensor, and a signal transmitter, for example Magnetic element or optical element, whose relative position to one another can be detected by the sensor device at least when the signal transmitter is in the detection area of the signal receiver. This ensures simple and inexpensive determination of the closed position of the closing element.

Furthermore, it is preferably provided that the signal receiver and / or the inclination sensor on the one hand and the lighting means on the other hand are arranged on a common printed circuit board. This ensures a compact design of the storage compartment and also ensures simple and time-saving assembly of the storage compartment.

The invention will be explained in more detail below with reference to the drawing. To show

FIG. 1 shows a storage compartment of a motor vehicle in a simplified representation, and

FIGS. 2A to 2C show the functionality of the storage compartment on the basis of simplified representations.

FIG. 1 shows, in a simplified perspective sectional illustration, a storage compartment 1 according to an advantageous exemplary embodiment for a motor vehicle not shown in detail here.

The storage compartment 1 has a trough-shaped housing part 2 which has an opening 3 through which a user can move an object into the interior of the housing part 2 and place it there, or through which the user can remove the object from the housing part 3. The opening 3 is assigned a closing element 4, which as a Pivot axis 5 is formed on the housing part 2 pivotably mounted flap 6. The closing element 4 is designed in such a way that it can be pivoted between a closed position and an open position, in particular completely closing the opening 3 of the housing part 2 in the closed position so that access to the interior of the housing part 2 is blocked, and in the open position it is released so that the user can use the

Can use interior of the housing part 2 or the shelf formed therefrom. In FIG. 1 the closing element is shown once in the closed position according to position A and once in the open position according to position B.

According to the present exemplary embodiment, the closing element 4 has a first section 7 which, when used as intended or when the storage compartment 1 is arranged as intended in a motor vehicle, extends at least substantially horizontally when the closing element 4 is in the closed position. The first section 7 is followed by an end section 8 which is inclined to the section 7 in the direction of a bottom of the base part, so that the end section 8 also forms an end wall of the storage compartment 1. On its outside, that is to say on its side facing away from the interior of the housing part 2, the end section 8 has a

Actuating handle 9, by means of which a user can simply grip the closing element 4 and, for example, pull it from the closed position into the open position, as shown in position B in FIG. The end portion 8 is on that of the

Pivot axis 5 facing away from the end of the closing element 4 formed.

A lighting device 10 is also arranged on the end section 8, which has at least one controllable lighting means 11, which is designed to at least substantially cover the interior of the housing part 2 or the storage compartment 1

to illuminate. In this context, “at least essentially illuminating” is to be understood as meaning that more than 50% of the light emitted by the illuminant falls into the interior of the housing part when the closing element 4 is open. For this purpose, the lighting means 11 is arranged on the inside of the end section 8. The lighting means 11 is arranged on a circuit board 17, on which a sensor device 12 is also arranged. According to the present exemplary embodiment, the sensor device 12 has an inclination sensor 13 which is fastened on the same circuit board 17 as the lighting means 11

The lighting device and / or the sensor device also have a control unit and a non-volatile memory, the control unit being designed to, depending on the inclination angle detected by the inclination sensor 13

Closing element 4 to see whether the closing element 4 is in the

Closed position or in the open position. According to the present exemplary embodiment, the closing element 4 is mounted so as to be pivotable by a pivot angle of 42 °, the storage compartment 1 at

Intended use is aligned such that a horizontal alignment of the inclination sensor 13 and thus the end portion 8 in a displacement position of the

Closing element 4 lies between the open position and the closed position, but closer to the open position. According to the present exemplary embodiment, the starting position or the horizontal position (0 °) is at a pivot angle of ai = -17 ° below the open position and + 25 ° above the closed position.

The lighting device 10 is now designed to show the lighting means 11 in

To be controlled depending on the pivot position of the closing element 4, ie to activate and deactivate. For this purpose, the control unit compares the current one, for example

Angle of inclination, which is detected by inclination sensor 13, with stored limit values or characteristic values in the non-volatile memory. In the present case, a

Switching angle 03 close to the horizontal orientation at 0 ° as a switching criterion for the

Illuminant 13 selected. In particular, the switching angle is approximately 5 ° to 10 °, in particular 4 ° below the horizontal position, as shown in FIG. The switching point or the switching angle is thus more than 15 ° apart from the open position and the closed position. The advantageous design of the storage compartment ensures, in particular, that there is no incorrect operation of the lighting means 11 even when the maximum road gradient and thus a correspondingly wide pivoting of the storage compartment 8 takes place. In particular, this ensures that when the storage compartment 8 is open, the

The lighting remains switched on, even if the road gradient changes by 30 °. The same applies in the event that the storage compartment is closed. According to a further exemplary embodiment, two switching angles are specified, one for switching on when the closing element is opened and one for switching off when the closing element is moved into its closed position. Depending on the change in angle, the

Inclination sensor detected whether it is a closing or an opening when the closing element is moved. This is a particularly flexible design of the

Opening angle allows. The tolerance of the switching point is preferably

or the detection of a closed or open state of the closing element depending on the accuracy and the sensor used and the effort of the evaluation.

FIGS. 2A to 2C show, in simplified representations, the behavior of the storage compartment or the lighting device 10 of the storage compartment with different road gradients. FIG. 2A shows the behavior with a road gradient of 0%. At 0 °, the horizontal alignment of the inclination sensor or the end section 8 of the Closing element 4 is shown. The dashed line 14, which is inclined by the switching angle a3 from the starting position of 0 ° by the swivel angle 03, divides the swivel range into a swivel range I in which the lighting means 1 is activated and one

Pivoting range II, between the line 14 and the closed position of the closing element, in which the lighting means 11 is deactivated. If the driver swivels the closing element 1 from the closed position B into the open position A in this state, reliable activation of the lighting means 11 is ensured. Accordingly, the lighting means 11 is reliably deactivated when the closing element 4 is pivoted into the closed position B.

FIG. 2B shows the situation at a point in time at which the road inclination relates to 15 ° when driving uphill, and FIG. 2C shows the same situation when the road inclination is -15 ° (downhill).

It can be seen that in the case of a maximum uphill as well as downhill incline, accidental activation or deactivation of the lighting means 11 does not occur due to the advantageous design of the storage compartment 1. Although the proportions of areas I and II change according to the road inclination to one another, it is ensured that the light source is deactivated even with a maximum incline when driving uphill when the closing element 4 is closed, as well as with a maximum incline when driving downhill (downhill slope). This prevents the lighting means 11 from being activated in the closed state, so that light could emerge from the joints between the closing element and the housing part 2 and have a disruptive effect. In addition, energy is saved because when the storage compartment 1 is closed, the lamp always remains deactivated.

As an alternative to the provision of the inclination sensor 13 or in addition thereto, the

Sensor device at least one further sensor that works without contact, in particular a Hall sensor, a reed contact, a capacitive sensor and / or an optical sensor. These have in common that they each have a signal receiver 15 arranged on the closing element 4 and a signal transmitter 16 arranged on the base part, the signal receiver 15 being designed to detect the presence of the signal transmitter 16. The sensor device is expediently designed in such a way that the presence of the signal transmitter 16 is only detected in the immediate vicinity of the signal receiver 15, so that the closed position of the closing element 4 can thereby be reliably detected. This serves, for example, to check the plausibility of the activation of the lighting means 11 determined by the inclination sensor 13 or as an alternative thereto.

While the present embodiment describes a center console storage compartment and shows it in the figures, according to a further embodiment, the storage compartment is as Trunk of a motor vehicle, designed as a dashboard compartment or glove compartment, or, for example, as a storage compartment in or on a vehicle seat.
