The invention relates to a decoupling element (8) for an ultrasonic sensor (1) which can be mounted on a two-dimensional component (6) for a vehicle (5) having a cutout (7), the ultrasonic sensor (1) having a cylindrical ultrasonic transceiver element (3) which can be introduced into the cutout (7). The decoupling element (8) has: a hollow cylindrical element (15) for surrounding the cylindrical ultrasonic transceiver element (3) of the ultrasonic sensor (1); and a plurality of support ribs (13) arranged on the outside of the hollow cylindrical element (15) in the radial direction and spaced apart from each other in the circumferential direction of the hollow cylindrical element (15) for supporting the hollow cylindrical element (15) when the axial end of the cylindrical ultrasonic transceiver element (3) is introduced into the cutout (7) together with the hollow cylindrical element (15) surrounding the cylindrical ultrasonic transceiver element (3). The decoupling element (8) is supported on the region of the two-dimensional part (6) outside the cut-out (7). Each support rib (13) is shaped like an arch when viewed in the axial cross-section of the decoupling element (8), which is open in the axial direction towards the other axial end of the hollow cylindrical element (15).
本发明提供了一种用于超声波传感器(1)的解耦元件(8),超声波传感器(1)可以装配在用于车辆(5)的具有切口(7)的二维部件(6)上,超声波传感器(1)具有可以引入切口(7)中的圆柱形超声波收发器元件(3)。解耦元件(8)具有:中空圆柱形元件(15),用于包围超声波传感器(1)的圆柱形超声波收发器元件(3);以及多个支撑肋(13),沿径向方向布置在中空圆柱形元件(15)的外侧,并且在中空圆柱形元件(15)的周向方向上彼此间隔开,用于当圆柱形超声波收发器元件(3)的轴向端与包围圆柱形超声波收发器元件(3)的中空圆柱形元件(15)一起被引入切口(7)中时,将解耦元件(8)支撑在切口(7)外侧的二维部件(6)的区域上。当在解耦元件(8)的轴向截面中观察时,每个支撑肋(13)的形状类似于拱门,其在轴向方向上朝向中空圆柱形元件(15)的另一轴向端开口。
