Describe in detail.
Flexible PCB 13 be arranged on ultrasound wave sound head 3 and ultrasound probe 1 standing part 11 it
Between, it is used for realizing electricity and/or signal connects.According to the present invention, draw from ultrasound wave sound head 3 and prolong
The Part I 13a of the flexible PCB 13 reaching rotating shaft 5 is fixed in rotating shaft 5 so that turning
In the rotary course of axle 5, the Part I 13a of flexible PCB 13 does not moves relative to rotating shaft 5.
Second of flexible PCB 13 between the standing part 11 of ultrasound probe 1 is extended to from rotating shaft 5
Part 13b is arranged around rotating shaft 5 winding, and extends past standing part 11 unceasingly.According to need
, the Part II 13b of flexible PCB 13 can wind a circle or multi-turn around rotating shaft 5.Second
Part 13b can be helically wrapped around rotating shaft 5, but Part II 13b is preferably around rotating shaft 5
Wind at same position or same position to reduce space requirement.
From the Part I 13a of the flexible PCB 13 of ultrasound wave sound head 3 extraction when close to rotating shaft 5
Bend through several times, in order to can contact with rotating shaft 5 with its planar section.Part I 13a with
Arranging porose 15 on flexible PCB 13 between Part II 13b, it is right to be also equipped with in rotating shaft 5
The hole 17 answered, through the screw (not shown) in hole 15 and 17 by the Part I of flexible PCB 13
13a is fixed in rotating shaft 5, as shown in Figure 2.It is understood that can also use the most bonding
The Part I 13a of flexible PCB 13 is fixed in rotating shaft 5 by alternate manner.In order to contribute to by
The Part I 13a of flexible PCB 13 is fixed in rotating shaft 5, preferably cuts out recessed in rotating shaft 5
Groove 19, so, flexible PCB 13 can relevantly coordinate on the flat bottom surface of groove 19.Around
The Part II 13b standing part at ultrasound probe 1 of the flexible PCB 13 that rotating shaft 5 winds
Fixed relative to standing part 11 at 11, in order to Part II 13b in the rotary course of rotating shaft 5
The part extending past standing part 11 is not produced relative to the housing of standing part 11 or ultrasound probe
Raw relative motion.
Although in the illustrated embodiment, respectively arranging a flexible electrical on ultrasound wave sound head 3 lateral symmetry ground
Road plate 13, but can be at ultrasound wave sound head 3 with fixing according to the needs realizing electricity and/or signal connection
Only arrange one between part 11 or the flexible PCB 13 of more than two is set.Multiple soft arranging
In the case of property circuit board 13, the plurality of flexible PCB 13 can be arranged on ultrasound probe 13
Both sides or the same side.
In the case of ultrasound wave sound head 3 lateral symmetry ground respectively arranges a flexible PCB 13, two
Flexible PCB 13 can wind along equidirectional around rotating shaft 5.At flexible PCB 13
Two parts 13b, along with the reciprocating rotary of rotating shaft 5 then when rolling tightly or unclamp, can produce in rotating shaft 5 and support
Resist or hinder this power rolling tightly or unclamping, thus, two flexible PCBs 13 are preferably along on the contrary
Direction winds around rotating shaft 5 so that the opposing of two flexible PCB 13 countershaft 5 generations or obstruction
This power rolling tightly or unclamping is cancelled out each other, to reduce the vibration of rotating shaft 5 and to reduce kinetic energy consumption.
In the case of more than two flexible PCB 13 is set between ultrasound wave sound head 3 and standing part 11,
Adjacent flexible circuit board 13 can wind along equidirectional around rotating shaft 5, but preferably along on the contrary
Direction winds around rotating shaft 5.
During ultrasound probe 1 works, rotating shaft 5 can be high under the driving effect of drive mechanism 9
Speed ground reciprocating rotary, drives ultrasound wave sound head 3 high speed swinging, in order to obtain ultrasound wave from measurand
Signal.Ultrasonic signal is through flexible PCB 13 and the cable that is connected with flexible PCB 13 (not
Illustrating) transmission is to main frame, thus obtain the ultrasonography of measurand.High at ultrasound wave sound head 3
During speed swings, ultrasound wave sound head 3, the Part I 13a of flexible PCB 13 and rotating shaft 5
It it is geo-stationary.Owing to the Part II 13b of flexible PCB 13 extends past standing part 11
And fixed relative to standing part or housing at standing part 11, at ultrasound wave sound head 3 at a high speed
During swing, the only bearing from rotating shaft 5 is to the Part II 13b standing part 11
Axle center O around rotating shaft 5 rotates.This rotation is converted into Part II 13b and exists relative to rotating shaft 5
Rolling tightly of one direction A or unclamping at another direction B, as shown in Figure 3.Can be seen by Fig. 3
Go out, with flexible PCB 13 not around rotating shaft 5 winding set-up mode compared with, flexible PCB 13
Set-up mode around rotating shaft 5 winding makes the lifting surface area of flexible PCB dramatically increase, unit plane
The long-pending shearing force being subject to will diminish, such that it is able to significantly improve the bending number of times of flexible PCB, improve
Reliability also extends its service life, and finally improves making of ultrasound probe and ultrasonic system
With reliability the service life extending them.
Although above by reference to accompanying drawing to the present invention have been described in detail, but the present invention is not limited to above-mentioned
Preferred embodiment.Such as can also be according to phase between the photographic head of the high speed rotating of watch-dog with its main frame
With mode, flexible PCB is set.It is also possible to be used at reciprocating rotary object with static
Other flexible board in addition to flexible PCB is set between object.It should be understood that without departing from this
In the case of the claimed scope of invention, those skilled in the art can carry out multiple amendment to the present invention.
