DETAILED DESCRIPTION OF THE DRAWINGS

(3) Exemplary embodiments and the technical background of the invention will be described in detail hereunder with reference to FIGS. 1 and 2. The same and the equivalent elements and components, or elements and components of equivalent function, are identified by the same reference signs. The detailed description of the identified elements and components is not repeated in each case when the latter are present.

(4) The features illustrated and further properties can be isolated from one another in any form, and be combined with one another in an arbitrary manner, without departing from the core concept of the invention.

(5) FIG. 1 in a perspective and partially sectional lateral view shows an embodiment of the component arrangement 110 according to the invention while using a line arrangement 10 which is designed according to the concept according to the invention.

(6) The component arrangement 110 shown in FIG. 1 is composed of a component 50 in the manner of a longitudinal chassis beam 101 of a vehicle body in a multi-chamber construction mode having a plurality of chambers 53 which are surrounded and formed by a housing 52 of the component 50 and which thus form the interior 55 of the component 50.

(7) A design embodiment of the line arrangement 1 according to the invention is assembled in one of the chambers 53 of the component 50, and the line arrangement 1 along the x-direction in terms of the xyz tripod as the external coordinate system extends through the provided chamber 53 in the longitudinal extension of the latter.

(8) The line arrangement 1 is composed of a line 10 having a plurality of, here two, rigid segments 11 which are connected to one another by a flexible connection element 12.

(9) One assembly element 15 in the manner of a ring is in each case configured on the external circumference of the rigid segments 11, the ring by way of the external circumference thereof being supported in a flexible manner on the internal faces of the walls of the housing 52 of the component 50 that form the chamber 53 in order to mount the line 10 in a vibration-damped manner in the interior 55 of the component 50.

(10) FIG. 2 in a schematic and sectional front view shows a design embodiment of the working device 100 according to the invention while using a component arrangement 110 designed according to the invention, having a line arrangement 1 according to the invention in a chamber 53 of a component 50.

(11) The component arrangement 110 may have the structure illustrated in FIG. 1, but this is not mandatory.

(12) The working device 100 illustrated in FIG. 2, for example in the form of a vehicle, is furthermore formed by further frame elements 103 and 104 which are attached to the chassis beam 101. The frame element 103 on the lower side thereof supports, for example, a battery module of an electric vehicle or of a hybrid vehicle as a design embodiment of the working device 100 according to the invention. In this case, the line 10 of the line arrangement 1 can be formed by a power supply line which transmits electric power from the battery module 102 to an apparatus which is to be supplied with power.

(13) However, other concepts of application are also conceivable, for example with a view to signal lines or the like. Furthermore conceivable are also applications of the invention in which the component 50 is not formed by a body element, for example by a chassis beam, but by a housing, for example also by a housing of a battery module or the like.

(14) The concept according to the invention can thus be applied wherever a line is to be routed through a cavity or a chamber of a component, and a simple, stable and reliable assembly in association with an ideally low level of technical and labor-related complexity is important.

(15) These and further features and properties of the present invention will be further explained by means of the following presentation.

(16) The integration of the line routing, for example for coolant or electric current, represents a great challenge, in particular in the case of battery-powered electric vehicles, the latter understood to be a working device 100, having a large high-voltage flat battery as the battery module 102 in the underfloor region.

(17) Lines 10 are conventionally routed on the external structure of the body or on as well as in the HVS housing.

(18) This leads to an additional installation space requirement, and in the case of the body structure to an effective enlargement of the longitudinal chassis beam structures. This can compromise the comfortable access to a vehicle, for example. The installation space for battery cells is reduced in the case of the lines being routed in the HVS housing.

(19) The integration of the lines can take place in a manner that is neutral in terms of the installation space by integrating the line routing into the body structure, for example laterally in the longitudinal chassis beam, or in the sill. The lines 10 can be routed in a chamber 53 of a multi-chamber profile, for example. With a view to ensuring the ease of assembly, the line 10 is embodied so as to be pliable and from a plurality of rigid segments 11 having flexible connection pieces 12 therebetween.

(20) Vibration-damping elements 15, for example from rubber, are in particular attached in order for the line 10 to be fixed in the chamber 53. The flexible connection pieces 12 in geometric terms can furthermore be embodied such that the flexible connection pieces 12, for example on account of a helical shape, are supported on the internal walls in the profile chamber 53. This shape can optionally be assumed by the line only in the final installed position, for example by collapsing the line 10.

(21) Fixing by further elements, for example in a form-fitting manner, can take place at the ends of the longitudinal chassis beam chamber 53, wherein a variation of the length and/or a displacement of the line 10 is possible by way of a fixed/floating mounting.

(22) The invention results in advantages such as a reduction of the installation space requirement for the routing of the lines on account of the structurally integrated approach, an improvement of the installation space for battery cells, and thus m terms of the range of the vehicle. Improvements in terms of the access for occupants are also possible.
