Abstract

An underride guard for a motor vehicle for arrangement below a high-voltage battery of the motor vehicle. The underride guard is plate-shaped, has a first surface, at least one plastic layer and at least one electrical component arrangement which includes at least one associated electrical line. In particular, the at least one electrical line is arranged on a support and is embedded together with the support in the plastic layer or is arranged on the plastic layer.

First claim

1 . An underride guard for a motor vehicle for arrangement below a high-voltage battery of the motor vehicle, comprising:
a plate-shape, a first surface, at least one plastic layer, and at least one electrical component arrangement which comprises at least one associated electrical line, wherein the at least one electrical line is arranged on a support and is embedded in the plastic layer together with the support; or is arranged on the plastic layer.

2 . The underride guard according to claim 1 , wherein the support is provided as a substrate which comprises reinforcing fibers, preferably glass fibers, in particular is provided as a reinforcing fiber fleece.

3 . The underride guard according to claim 1 , wherein the plastic layer represents the support and is designed as a circuit board substrate and the at least one electrical line is applied in the form of at least one conductor track on the first surface of the underride guard provided by the at least one plastic layer; and/or
the at least one electrical line together with the support formed separately from the plastic layer is applied on the first surface of the underride guard provided by the at least one plastic layer.

4 . The underride guard according to claim 1 , wherein the at least one electrical line is embedded in the at least one plastic layer as part of an induction charging coil included in the component arrangement and/or a heating device.

5 . The underride guard according to claim 1 , wherein the at least one electrical component arrangement comprises at least one sensor and the at least one conductor track represents a sensor line for conducting measurement signals from the sensor, wherein the sensor line is guided from the sensor to a connection point of the underride guard, in particular wherein the at least one sensor and/or the connection point are arranged on the first surface of the underride guard.

6 . The underride guard according to claim 1 , wherein the at least one sensor is designed to detect a parameter, a property and/or a defect of the high-voltage battery independently of damage and/or deformation of the underride guard, in particular wherein the at least one sensor represents at least one of the following:
a temperature sensor, a moisture sensor and/or liquid sensor, and a harmful gas sensor.

7 . The underride guard according to claim 1 , wherein the underride guard has a deformation and/or intrusion sensor, with which a second electrical line is associated, which is embedded in the at least one plastic layer.

8 . The underride guard according to claim 1 , wherein the at least one plastic layer is designed as a fiber-reinforced plastic layer.

9 . A motor vehicle having an underride guard according to claim 1 .

10 . A method for producing an underride guard for a motor vehicle for arrangement below a high-voltage battery of the motor vehicle, wherein the underride guard
is plate-shaped, with a first surface and with at least one plastic layer, and is designed with at least one electrical component arrangement which comprises at least one associated electrical line, wherein the at least one electrical line is arranged on a support and is embedded together with the support in the plastic layer or is arranged on the plastic layer.

11 . The underride guard according to claim 2 , wherein the plastic layer represents the support and is designed as a circuit board substrate and the at least one electrical line is applied in the form of at least one conductor track on the first surface of the underride guard provided by the at least one plastic layer; and/or
the at least one electrical line together with the support formed separately from the plastic layer is applied on the first surface of the underride guard provided by the at least one plastic layer.

12 . The underride guard according to claim 2 , wherein the at least one electrical line is embedded in the at least one plastic layer as part of an induction charging coil included in the component arrangement and/or a heating device.

13 . The underride guard according to claim 3 , wherein the at least one electrical line is embedded in the at least one plastic layer as part of an induction charging coil included in the component arrangement and/or a heating device.

14 . The underride guard according to claim 2 , wherein the at least one electrical component arrangement comprises at least one sensor and the at least one conductor track represents a sensor line for conducting measurement signals from the sensor, wherein the sensor line is guided from the sensor to a connection point of the underride guard, in particular wherein the at least one sensor and/or the connection point are arranged on the first surface of the underride guard.

15 . The underride guard according to claim 3 , wherein the at least one electrical component arrangement comprises at least one sensor and the at least one conductor track represents a sensor line for conducting measurement signals from the sensor, wherein the sensor line is guided from the sensor to a connection point of the underride guard, in particular wherein the at least one sensor and/or the connection point are arranged on the first surface of the underride guard.

16 . The underride guard according to claim 4 , wherein the at least one electrical component arrangement comprises at least one sensor and the at least one conductor track represents a sensor line for conducting measurement signals from the sensor, wherein the sensor line is guided from the sensor to a connection point of the underride guard, in particular wherein the at least one sensor and/or the connection point are arranged on the first surface of the underride guard.

17 . The underride guard according to claim 2 , wherein the at least one sensor is designed to detect a parameter, a property and/or a defect of the high-voltage battery independently of damage and/or deformation of the underride guard, in particular wherein the at least one sensor represents at least one of the following:
a temperature sensor, a moisture sensor and/or liquid sensor, and a harmful gas sensor.

18 . The underride guard according to claim 3 , wherein the at least one sensor is designed to detect a parameter, a property and/or a defect of the high-voltage battery independently of damage and/or deformation of the underride guard, in particular wherein the at least one sensor represents at least one of the following:
a temperature sensor, a moisture sensor and/or liquid sensor, and a harmful gas sensor.

19 . The underride guard according to claim 4 , wherein the at least one sensor is designed to detect a parameter, a property and/or a defect of the high-voltage battery independently of damage and/or deformation of the underride guard, in particular wherein the at least one sensor represents at least one of the following:
