Embodiment Construction

[0024] The following is attached Figure 1-3 The present invention is described in detail.

[0025] figure 1 The ultrasonic probe of the ultrasonic system according to the present invention is schematically shown, wherein the casing is removed to clearly show its inner structure. Such as figure 1 As shown, the ultrasonic probe 1 includes an ultrasonic sound head 3 in which a plurality of ultrasonic transducer elements are arranged for generating incident ultrasonic waves and receiving reflected ultrasonic waves. The ultrasonic probe 1 also includes a rotating shaft 5 to which the ultrasonic head 3 is fixed and reciprocally rotates (or swings) therewith, and the rotating shaft 5 is rotatably fixed to a frame housing (not shown) through a bearing 7 . The rotating shaft 5 can rotate reciprocally at high speed under the driving action of the driving mechanism 9 in any suitable known manner, and the driving mechanism 9 preferably includes a stepping motor. In addition to the ul...

Abstract

The invention provides a method for connecting a reciprocating rotation object with a static object by utilizing a flexible plate. The reciprocating rotation object is fixed on a rotating shaft and can rotate together with the rotating shaft, a first part of the flexible plate extends from the reciprocating rotation object to the rotating shaft, and a second part of the flexible plate extends from the rotating shaft to the static object; and the method is characterized in that the first part of the flexible plate is fixedly arranged relative to the reciprocating rotation object and the rotating shaft, and the second part of the flexible plate is arranged by winding around the rotating shaft, so that the second part of the flexible plate can be wound up or unwound along with the reciprocating rotation of the rotating shaft. The invention further relates to an ultrasonic probe. According to the invention, the stress area of the flexible plate is significantly increased through the arrangement way of the flexible plate by winding around the rotating shaft, and the shearing force in a unit area can become small, so that the number of bending times of the flexible plate can be significantly improved, the reliability of the flexible plate is improved, and the service life of the flexible plate is prolonged, thus the reliability of the ultrasonic probe is improved and the service life of the ultrasonic probe is also prolonged.

Description

technical field [0001] The invention relates to a flexible board, in particular to a method for connecting a reciprocating rotating object and a stationary object by using a flexible board, and an ultrasonic probe including the connection. Background technique [0002] Flexible circuit boards are printed circuits made of flexible insulating substrates. They can be bent, wound, and folded freely, arranged arbitrarily according to the spatial layout, and can be moved and stretched arbitrarily in three-dimensional space, so they have a wide range of uses. In many modern electronic integrated devices, flexible circuit boards are widely used to realize electrical and / or signal connections between reciprocating rotating objects and stationary objects. Its typical applications are, for example, the flexible circuit board arranged in the ultrasonic probe of the ultrasound system, and the flexible circuit board arranged between the camera of the monitoring system and its host compute...
