Description

This invention relates particularly to a functional element used in automobiles, especially a block device for a damping device and/or separation device, wherein a free space is provided for the functional element and/or the damping device or separation device. In prior art, for example, functional elements and/or damping or isolation devices are used in automobiles to prevent vibrations from spreading within the vehicle. These functional elements are used in relation to the vehicle body, the vibrating engine components and other vibrating parts within the vehicle, and/or other areas within the vehicle. For example, International Publication No. 2020/001872 (Patent Document 1) discloses a vibration damping mechanism in which, for example, an engine and/or compressor is held within a linkage mechanism. The engine and/or compressor naturally generate vibrations during operation, which can be particularly disruptive to the vehicle's occupants. Therefore, the joint structure within the mechanism is provided with elastic elements, which are connected to the vehicle body via elastomers. The elastomers separate the vehicle body from the compressor as much as possible, i.e., dampen the vibrations emitted from the engine and/or compressor. The damping and/or isolation devices proposed in Patent Document 1 consist of various components that must be joined and assembled within appropriate openings in the vibration damping mechanism. Both the pre-assembly and final assembly are relatively complex and, consequently, costly. International Publication No. 2020/001872 This is a side view of one embodiment of the present invention, perpendicular to the cylindrical axis Z.This is a plan view of Figure 1a.Figures 1a and 1b are perspective views of the embodiments shown.This is a side view of another embodiment of the present invention.This is a view of Figure 2a rotated 90 degrees around the cylindrical axis Z.Figures 2a and 2b are plan views of the embodiments shown.This is a schematic cross-sectional view showing the functional elements and block apparatus of the present invention.Figure 3a is a plan view of the embodiment, and the cross-section of Figure 3a is shown along the line A-A.This is a cross-sectional view of a blocking device and functional elements, i.e., a damping device and/or separation device, according to another embodiment of the present invention.This is a perspective plan view of a functional element and block device according to another embodiment of the present invention. Figure 1a is a side view of a block device 100 according to the present invention. The block device 100 has a blocking extension 10 which is a cover and/or plate. Stabilizing struts (elongated members for stabilization) 10a are for providing the cover and/or plate 10 with as little material as possible and with sufficient stability. Two retaining parts 12, which are provided as struts (elongated members) 12 in this case, extend from the cover and/or plate 10. As can be seen from Figure 1b, a passage opening 16 for connecting members (not shown), such as retaining bolts, extends rotationally symmetrically about the cylindrical axis Z. The passage opening 16 has an anti-torsion retaining projection 14, which provides a retaining area, such as a clamping area, that can fix a functional element 22, such as a damping device and/or separation device 22, in a predetermined position. The assembly 14 can be molded from, for example, rubber, for example, by injection molding. Various plastics may also be considered for this purpose. As illustrated, the passage opening 16 is not circular; rather, in this embodiment, it has a non-circular contour, particularly to accommodate and hold a sleeve 18 with a corresponding non-circular cross-section in a fixed, non-rotatable state. The corresponding sleeve 18 may or may not consist of a structure for holding a stud bolt, such as an internal thread. The perspective view in Figure 1c specifically shows the strut (elongated member) fixing projection 14a. This projection 14a provides, on the one hand, a sleeve 18 of the corresponding shape (see Figures 4 and 5), and on the other hand, allows for the fixing of the functional element 22, particularly the damping device and/or separation device 22, in a predetermined position. Hereafter, the functional element 22 will be referred to as the separation device, but it may also be called the damping device. As illustrated, the separation device 22 is fixed to the block device 100 of the present invention by the accumulation of material for the anti-twist holding projection 14 and/or strut (elongated member) fixing projection 14a that provide the clamping area. Conversely, the pre-assembly and final post-assembly positioning of the functional elements can also be simplified by using adhesive instead of the clamping area. In the embodiment shown in Figures 2a-2c, two block extensions 10 are provided, each in which two holding parts and/or struts (elongated members)
