Definitions

  • the invention relates to a carrier element according to the
  • a carrier element according to the invention enables a particularly impact-resistant mounting of a shock-sensitive object, such as a shock-sensitive sensor.
  • the invention is based on the recognition that hardly occurs by the special design of the support element under force due to impact load, a substantial deformation of the support member in the connection region between the support member and the object.
  • the carrier element is designed substantially U-shaped and has two legs, which are interconnected by a bridge. Particularly advantageously, these two legs extend in a first region and in a third, opening into the bridge area, substantially parallel to each other, while extending arcuately in a second region. Particularly advantageously, the legs have a greater distance from one another in the first region than in the first region third area.
  • the height of the legs in the second region is preferably less than in the other areas, whereby the spring force of the legs can be advantageously influenced. Further advantageous embodiments and modifications of the invention will become apparent from the further dependent claims.
  • FIG. 1 shows a plan view of a carrier element
  • FIG. 2 shows a plan view of a carrier element fastened to a holding device and carrying an object
  • FIG. 3 shows a side view of the carrier element shown in FIG.
  • FIG. 1 shows a plan view of a carrier element 10 designed according to the invention.
  • the carrier element 10 is substantially U-shaped and comprises two legs 10.1, 10.2, which are connected to one another by a bridge 10.3.
  • the support member 10 can be roughly divided into three areas A, B and C.
  • the free ends of the legs 10.1, 10.2 of the carrier element 10 extend substantially parallel to one another.
  • the legs 10.1, 10.2 in this region A have a distance A1 which exceeds their distance C1 in the region C of the bridge 10.3 connecting them.
  • the legs 10.1, 10.2 are essentially arcuate and light curved inwards.
  • the respective width of the legs 10.1, 10.2 is denoted by A2, B2 and C2 in the different regions A, B, C of the carrier element 10.
  • said widths of the legs 10.1, 10.2 are substantially the same.
  • a rectangular coordinate system is shown in the figures.
  • the x and y axes lie in the plane of the drawing, while the Z axis is perpendicular to the plane of the drawing.
  • Figure 2 which also represents a plan view of a support member 10.
  • Figure 3 which is a side view of a support member 10
  • the y and z axes are in the plane of the drawing while the x-axis is perpendicular to the plane of the drawing.
  • FIG. 2 shows a plan view of a carrier element 10 fastened to a holding device and supporting an object 1.
  • the holding device is not shown in FIG.
  • the carrier element 10 is connected to the holding device in the attachment areas 3a, 3b.
  • the attachment areas 3a. 3b are in the region A of the free legs of the support member 10.
  • FIG. 2 extend the illustration in Figure 2 extend the
  • Attachment areas 3a, 3b almost over the entire length of the region A of the legs 10.1,102 of the support member 10.This is not mandatory, but depends on the individual application. The person skilled in the art will choose the length of the attachment regions 3a, 3b such that a secure mechanical connection between the carrier element 10 and the holding device is ensured.
  • the object 1 carried by the carrier element 10 is connected to the carrier element 10 at the bridge 10.3 connecting the legs 10.1, 10.2.
  • the connection between the object 1 and the carrier element 10 is denoted by reference numeral 4th - A -
  • the object 1 is a measuring reference element, such as, for example, a magnet for the deflection measurement in the weight sensor system.
  • the object 1 has a substantially cuboid shape.
  • FIG. 3 shows a side view of the carrier element 10. In this side view, the heights A3, B3, C3 of the legs 10.1, 10.2 of the carrier element 10 are shown. In the region A, the legs 10.1, 10.2 have the height A3, in the region C the height C3, with A3 and C3 having substantially the same value. In the area B, the legs 10.1, 10.2 become noticeably narrower.
  • the height of the legs 10.1, 10.2 in the region B decreases substantially uniformly so as to reach a minimum of the value B3 in the last third of the region B, for example.
  • the height of the legs 10.1, 10.2 then increases again up to the value C3. It follows that in the areas A and C, the respective height A3, C3 of the legs 10.1, 10.2 substantially exceeds their respective width A2, C2. Approximately in the last third of the area B, the height B3 of the legs 10.1, 10.2 substantially corresponds to their width B2.
  • the mode of operation of the carrier element 10 will be explained below.
  • the inventively designed support member 10 ensures a secure and shock-protected mounting of the shock-sensitive object 1 and the shock-sensitive compound 4.
  • By the much reduced in the area B height results in this area a lower spring stiffness of the legs 10.1,10.2 of the support member 10. This can Impact loads in the x direction are easier to catch.
  • the degree of slimming is determined so that the strain at the edges 21 of the region 20 is distributed as evenly as possible. Because the limbs 10.1, 10.2 in the region B of the carrier element 10 are arc-shaped, shock loads in the direction of the y-axis are also well absorbed. Due to the fact that the legs 10.1, 10.2 can resiliently yield to shock loads as a result of this embodiment, excessive loading of the connection area 4 is prevented. With a shock load in the direction of the arrow 50 (FIG.
  • the inventive solution allows a shock-resistant attachment of a shock-sensitive object to a support element.
  • the object can therefore also be used in applications in which rough environmental conditions, in particular impact loads, can be expected.
  • Particularly advantageous is the inventive solution for the attachment of sensors or measuring reference elements (eg magnets) to a support element. Since the connection area between the object and the carrier element is only exposed to comparatively low mechanical loads, inexpensive connection techniques can be used.
