AI Technical Summary

Technical Problem

During the installation of plastic housing modules of existing motor vehicles, the clamping elements of the metal cage are complex and costly. Due to tolerance issues, the screws and clamping elements need to be pre-tightened, which increases production cost and complexity.

Method used

The plastic housing device connected by indirect screws allows the clamping element to be installed and rotated in the z-direction through the coordination of the positioning element and the spring tab thread. The screws are automatically engaged when rotating. The tolerance is compensated by the motion of the spring tab, which simplifies the Installation process and reduce costs.

Benefits of technology

This simplifies the installation process, reduces production costs, and improves the installation accuracy and stability of module components in the vehicle, reducing the need to pre-tighten screws.

Description

Technical Field

[0001] The invention relates to a plastic housing arrangement for an indirect screw connection of an antenna module of a motor vehicle. Background Art

[0002] The (amplifier) ​​module with the plastic housing has an additional metal element (metal cage) on its underside, which is inserted into a corresponding installation hole in the vehicle (panel) and thus positions and aligns the module.

[0003] Furthermore, inside the metal element (metal cage) there is a clamping element which is held centrally by means of screws. Tightening the screws causes the clamping element to rotate 45° and move in the direction of the module base (plastic housing), thereby clamping the module to the vehicle panel.

[0004] The additional metal element (metal cage) requires costs and, due to the type of construction, requires a cumbersome installation of the clamping element from the side. In addition, due to the tolerance conditions, the screws must be screwed together with the clamping element in advance on the production line (additional costs). Summary of the invention

[0005] The object of the present invention is to provide an improved housing arrangement for a motor vehicle. This object is achieved by the subject matter of the basic concept of the present invention.

[0006] Embodiments and improvements can be found in the preferred embodiments of the invention, in the description and in the drawings.

[0007] A first aspect of the present invention relates to a plastic shell device for an indirect screw connection of a motor vehicle, wherein the plastic shell device comprises: at least one positioning element; a clamping element; and a screw element; wherein the at least one positioning element is configured to hold the clamping element in place in a form-fitting manner; wherein the screw element is configured to be pressed against the clamping element by the at least one positioning element and thereby cause the clamping element to rotate; wherein the clamping element is configured to clamp the plastic shell device to a metal panel by the rotation.

[0008] The invention advantageously makes it possible to reduce costs and simplify the installation process on the production line and allows to improve the tolerance situation within the module assembly and during the installation process in the vehicle.

[0009] The invention advantageously allows the function of a metal element (also called "metal cage") to be incorporated into a plastic housing (also called "housing bottom"). By means of corresponding snap hooks on the plastic housing, the clamping element can now be mounted in the z direction and held in place in a form-fitting manner.

[0010] The screw is pressed against the thread on the clamping element by means of a spring web in the plastic cover (also called "housing cover") and therefore does not require pre-tightening, since the threads engage immediately when the screw is turned. Tolerances are compensated by the spring travel of the web.

[0011] In an advantageous embodiment of the invention it is provided that the screw element is configured to engage with the spring tab when rotating.

[0012] In a further advantageous embodiment of the invention, it is provided that the plastic housing device is configured such that tolerances are compensated by correspondingly adapted spring travels of the spring webs attached to the plastic housing device.

[0013] In a further advantageous embodiment of the invention it is provided that the plastic housing arrangement is configured to allow installation of the module in a vehicle.

[0014] In a further advantageous embodiment of the invention it is provided that the plastic housing arrangement is configured to push the screw element in one direction.

[0015] The described embodiments and refinements can be combined with one another as required.

[0016] Further possible configurations, improvements and embodiments of the invention also include combinations of features of the invention which are described above or below with reference to the exemplary embodiments, which are not explicitly described.

[0017] The accompanying drawings are intended to convey a further understanding of the embodiments of the present invention. The accompanying drawings illustrate embodiments and are used to explain the concept of the present invention in conjunction with the description.

[0018] Other embodiments and many of the particular advantages will become apparent with reference to the accompanying drawings.The elements shown in the drawings are not necessarily shown in correct proportion relative to each other. BRIEF DESCRIPTION OF THE DRAWINGS
