Description

BRIEF DESCRIPTION OF THE DRAWING FIGURES

[0018] An exemplary embodiment of the invention will now be explained in further detail with reference to the drawings.

[0019] FIG. 1 shows a front end of a motor vehicle in the assembled state,

[0020] FIG. 2 shows the front end from FIG. 1 during a mounting operation, and

[0021] FIG. 3 shows the front end from FIGS. 1 and 2 during a removal operation.

DETAILED DESCRIPTION OF THE INVENTION

[0022] FIG. 1 discloses a front end 12 of a motor vehicle 10, wherein the motor vehicle 10 is an electric vehicle and substantially comprises an electric drive unit and a traction battery. The traction battery and the electric drive unit are not shown in the figures.

[0023] The front end 12 comprises a partition 22, which is arranged between a passenger compartment and a power compartment and separates the passenger compartment from the power compartment. The front end 12 further comprises two side members 26, 28 arranged parallel to one another and extending in the travel direction and a cross member 24 extending in the transverse direction of the vehicle. The cross member 24 is fixedly connected to the side members 26, 28. In the node points between the cross member 24 and the side members 26, 28, respectively, a suspension strut receptacle 30, 32 is arranged, which is fixedly connected to the cross member 24 and the respective side member 26, 28. The side members 26, 28, the cross member 24, and the suspension strut receptacles 30, 32 are components of a shell 20 of the motor vehicle 10.

[0024] The motor vehicle 10 further comprises a housing 40, which is fastened to the shell 20 via a mounting member 42. The mounting member 42 is made of a tube 44 having a rectangular cross section. Further, the housing is fastened to the shell 20 via an additional mounting member 62. The mounting member 42 is fastened to the cross member 24 at the side members 26, 28 on the end side and via member projections 46 extending in the travel direction. The additional mounting member 62 is fastened to one of the two suspension strut receptacles 30, 32 on each end side. In the vertical direction of the vehicle between the mounting member 42 and the additional mounting member 62, the housing 40 is arranged, wherein the housing 40 is fastened, in particular screwed, to the mounting member 42 with one side facing a roadway and with the opposite side to the additional mounting member 62.

[0025] An electronic component 36 is arranged in the housing 40, for example a control unit, and in particular in the case of an electric vehicle a battery management system. In the event of a failure of the electronic component 36, the electronic component 36 and thus the housing 40 must be easily removable.

[0026] FIG. 2 shows a mounting operation of the housing 40 on the shell 20 and FIG. 3 shows a removal operation of the housing 40.

[0027] During the mounting operation, the housing 40 is pre-mounted on the mounting member 42. The housing 40 includes a fastening tab 52 that abuts against the mounting member 42 in the travel direction and is fastened to the mounting member 42 via a plurality of screw elements 54, 56, 58, 60. The housing 40 continues to abut against an abutment surface 50 in the vertical direction of the vehicle on the mounting member 42 and thereby members the mounting member 42 in the vertical direction of the vehicle. In a mounting step subsequent to the pre-mounting of the housing 40 and the mounting member 42, the mounting member 42 is mounted together with the housing 40 on the shell 20, wherein the mounting member 42 is screwed onto the side members 26, 28 and the cross member 24. For mounting the mounting member 42 to the side members 26, 28, each side member 26, 28 comprises a fastening projection 46, 48 on the sides facing each other, wherein the mounting member 42 is placed into abutment in the travel direction on the fastening projections 46, 48 and screwed to the fastening projections 46, 48. Finally, the additional mounting member 62 is screwed to the suspension strut receptacles 30, 32, and the housing 40 is screwed to the additional mounting member 62.

[0028] The housing 40 is thus reliably fastened to the shell 20 on both sides, namely on the one hand by the mounting member 42 and on the other hand by the additional mounting member 62. The mounting member 42 and the additional mounting member 62 further stiffen the shell 20.

[0029] In a removal operation, the housing 40 is simply released from the additional mounting member 62, the additional mounting member 62 is removed, and the screw elements 54, 56, 58, 60 are released, thereby releasing the connection of the housing 40 from the mounting member 42. The housing 40 can then be guided out of a space bounded by the shell 20. The mounting member 42 remains in its mounted state. All removal steps are carried out from above, i.e. via the second side 72.

[0030] According to aspects of the invention, the mounting member 42 and the housing 40 are thus inserted into the space of the shell 20 via a first side 70 of the shell 20 facing the roadway, i.e. from below, and mounted on the shell 20, and, during a removal operation, the housing 40 is removed via a second side 72 opposite to the first side 70, i.e. from above. In this way, the housing 40 can be mounted and removed easily.

[0031] Structural embodiments other than the described embodiments, which fall within the scope of protection of the main claim, are possible as well. For example, the mounting member 42 or the shell 20 can be configured differently.
