Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic equipment, in particular to a driving mechanism for driving an ultrasonic probe. Background Art

[0002] Ultrasonic equipment usually includes an ultrasonic probe and an ultrasonic host. The ultrasonic probe includes a transducer that can convert electrical signals into ultrasonic signals. The ultrasonic host is responsible for controlling the electrical pulse to excite the transducer to emit ultrasonic waves, while receiving the echo signal obtained by the ultrasonic probe, and detecting and processing the signal.

[0003] The ultrasound probe also includes a transducer driving mechanism that drives the transducer. The transducer driving mechanism includes a driving motor. The driving motor drives the transducer to swing within a certain angle and scans and images the human body at each angle within the swing range, thereby constructing a three-dimensional image or a four-dimensional image of human tissue. In current clinical applications, the requirements for the roll rate of 4D ultrasound probes and the image frame rate of ordinary ultrasound probes are increasing, which requires the transducer in the ultrasound probe to have a higher movement speed and greater acceleration. When the weight of the transducer remains unchanged, a large part of the kinetic energy of the transducer during the reciprocating swing is converted into vibration noise, resulting in the technical problem of high noise of the ultrasound probe.

DETAILED DESCRIPTION

[0070] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0071] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0072] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0073] At present, the transducer in the ultrasonic probe has a high speed and acceleration when working, which causes a lot of noise in the ultrasonic probe. Usually, process optimization is used to reduce the weight of the transducer, but in some cases, the weight of the transducer cannot be reduced, and the performance of the ultrasonic probe cannot be reduced. At present, there are also motors with stronger driving capabilities to solve the problem of the sound head losing steps during acceleration or deceleration to meet the working needs of the transducer, but this method requires a great increase in cost.

[0074] The present application provides an elastic conduction structure on the power path between the drive motor and the transducer in the ultrasonic probe, which can store energy and buffer energy during acceleration and deceleration, thereby reducing vibration noise in the ultrasonic probe. In addition, the elastic member can be used to compensate the power of the drive motor when releasing elastic potential energy, thereby reducing the power requirement of the drive motor. The present application is described in detail below in conjunction with specific implementation methods.

[0075] For some examples, please refer to Figures 1 to 5The ultrasonic probe comprises a transducer mounting seat 1, a transducer 2 and a transducer driving mechanism 3. The transducer driving mechanism 3 and the transducer 2 are both arranged on the transducer mounting seat 1. The transducer 2 is used to convert an electrical signal into an ultrasonic signal.

[0076] In one embodiment, the ultrasound probe is a 4D probe. Of course, in some other embodiments, the ultrasound probe may also be other types of probes, such as a 3D probe or a 2D probe.

[0077] For some examples, please refer to Figures 1 to 3 The transducer drive mechanism 3 includes a drive motor 31, a driving rotating member 32, a driven rotating member 33 and at least one elastic member 34. The drive motor 31 is used to drive the driving rotating member 32 to rotate forward and reverse; the driving rotating member 32 and the driven rotating member 33 are arranged in a manner that they can rotate relative to each other by a set distance. Figure 4 The elastic member 34 forms an elastic conduction structure between the active rotating member 32 and the driven rotating member 33, so that the active rotating member 32 can drive the driven rotating member 33 to rotate forward and reverse through the elastic member 34, and the driven rotating member 33 is connected to the transducer 2 to drive the transducer 2 to swing back and forth.

[0078] The force and motion output by the active rotating member 32 are transmitted to the driven rotating member 33 through the elastic member 34, and then the driven rotating member 33 drives the transducer 2 to swing back and forth. Since the elastic member 34 is located on the power transmission path between the active rotating member 32 and the driven rotating member 33, when the active rotating member 32 and the driven rotating member 33 rotate relative to each other, the elastic member 34 can store energy through elastic deformation, absorb the kinetic energy of the transducer 2 and the transducer driving mechanism 3, reduce the mechanical impact between the active rotating member 32 and the driven rotating member 33, and then form a buffer between the transducer 2 and the transducer driving mechanism 3.

[0079] The elastic conductive structure can be of any feasible type, for example, see Figures 3 to 8, which may be the first elastic member 341 and the second elastic member 342 to be described below. When the active rotating member 32 and the driven rotating member 33 rotate relative to each other, the first elastic member 341 and the second elastic member 342 can be compressed to store and release potential energy through elastic deformation; for another example, the active rotating member 32 is an active disk, and the driven rotating member 33 is a driven disk. The active disk and the driven disk are both provided with corresponding elastic member mounting holes. A part of the elastic member 34 is in the elastic member mounting hole of the active disk, and another part is in the elastic member mounting hole of the driven disk. The active disk and the driven disk are matched with a gap in the axial direction. When the active disk and the driven disk rotate relative to each other, the elastic member 34 can be compressed. In this way, when the active disk rotates, the elastic member 34 transmits the force to drive the driven disk to move; for another example, the elastic member 34 may be an elastic shaft connected between the active rotating member 32 and the driven rotating member 33, and the elastic shaft may be made of elastic rubber.

[0080] For some examples, please refer to Figure 3 , Figures 5 to 8 , the number of elastic members 34 is at least two, at least one of which is a first elastic member 341, and at least one is a second elastic member 342. The drive motor 31 is used to drive the active rotating member 32 to rotate forward and reverse. In one embodiment, the drive motor 31 is a stepper motor. In some other embodiments, the drive motor 31 can be a servo motor.

[0081] The driven rotating member 33 is connected to the transducer 2 to drive the transducer 2 to swing back and forth. The connection between the driven rotating member 33 and the transducer 2 includes both direct connection and indirect connection. The indirect connection is that a transmission member is provided between the driven rotating member 33 and the transducer 2, and the driven rotating member 33 drives the transmission member to move, and the transmission member drives the transducer 2 to swing back and forth.

[0082] Regarding the direct connection method, the direct connection includes a stop connection between the driven rotating member 33 and the transducer 2, that is, a stop structure is provided between the driven rotating member 33 and the transducer 2 to limit the relative rotation between the two, such as a stop groove is provided on one of the driven rotating member 33 and the transducer 2, and a stop protrusion is inserted into the stop groove on the other; direct connection also includes a fixed connection, such as the driven rotating member 33 and the transducer 2 are fixed together by fasteners, and another example is that the driven rotating member 33 and the transducer 2 are welded together or integrated together as one piece.

[0083] Regarding the indirect connection method, the indirect connection includes an indirect movable connection and an indirect fixed connection. The indirect movable connection method includes the driven rotating member 33 being movably connected to the transducer 2 through a movable mechanism or movable member such as a connecting rod mechanism, a gear system, etc., and the indirect fixed connection includes the driven rotating member 33 being connected together through a fixed member fixed to the driven rotating member 33 or the transducer 2. For example, in one embodiment, the driven rotating member 33 is indirectly connected to the transducer 2 through a transducer bracket 4. The specific connection structure will be described in detail below.

[0084] Please refer to Figures 4 to 8 The active rotating member 32 has an active stopper 321, and the driven rotating member 33 has a driven stopper 331. The number of at least one of the driven stopper 331 and the active stopper 321 is at least two, and the driven stopper 331 is located in the rotation direction of the corresponding active stopper 321, that is, the active stopper 321 and the driven stopper 331 are arranged in the rotation direction of the active rotating member 32. The driven stopper 331, the active stopper 321, the first elastic member 341 and the second elastic member 342 form at least one energy storage and vibration reduction structure. In any of the energy storage and vibration reduction structures, a first gap 35 is formed between the active stopper 321 and the driven stopper 331 (please refer to Figure 4 ) and the second gap 36 (see Figure 4 ), the first elastic member 341 is located in the first gap 35, and the active stopper 321 and the driven stopper 331 on both sides of the first gap 35 always keep squeezing the first elastic member 341. The second elastic member 342 is located in the second gap 36, and the active stopper 321 and the driven stopper 331 on both sides of the second gap 36 always keep squeezing the second elastic member 342.

[0085] The first elastic member 341 and the second elastic member 342 store energy by deformation. The first elastic member 341 and the second elastic member 342 can be common elastic members 34, such as springs, elastic blocks or reeds. The elastic block can be a rubber block. The elastic block can be fixed to the active stopper and / or the driven stopper by bonding or partially embedding, or can be fixed to the active stopper and / or the driven stopper by fasteners.

[0086] The first gap 35 and the second gap 36 can be arranged in any feasible manner. For example, in an energy storage vibration reduction structure, the number of active stop parts 321 and the number of driven stop parts 331 are both two, a first gap 35 is formed between one active stop part 321 and one driven stop part 331, and a second gap 36 is formed between another active stop part 321 and another driven stop part 331; for another example, in an energy storage vibration reduction structure, the number of active stop parts 321 is one, the number of driven stop parts 331 is two, and in the rotation direction of the active rotating member 32, the number of active stop parts 321 is Between the two driven stoppers 331, the active stopper 321 forms a first gap 35 with the driven stopper 331 on one side, and forms a second gap 36 with the driven stopper 331 on the other side; for another example, in an energy storage vibration reduction structure, there are two active stoppers 321 and one driven stopper 331. In the rotation direction of the active rotating member 32, the driven stopper 331 is located between the two active stoppers 321, and the driven stopper 331 forms a first gap 35 with the active stopper 321 on one side, and forms a second gap 36 with the active stopper 321 on the other side. The above arrangement is limited to the case where the first gap 35 and the second gap 36 are one.

[0087] As required, the number of the first gaps 35 and the second gaps 36 can be any other number. For example, when the number of the active stoppers 321 and the number of the driven stoppers 331 are both two, the active stoppers 321 and the driven stoppers 331 can be arranged crosswise. In this case, the number of the first gaps 35 is two or the number of the second gaps 36 is two. For another example, please refer to Figures 6 to 8 When there are two active stoppers 321 on the active rotating member 32 and two driven stoppers 331 on the driven rotating member 33, there are two energy storage and vibration reduction structures, and the two energy storage and vibration reduction structures share the active stopper 321. At this time, there are two first gaps 35, and the two first gaps 35 belong to the two energy storage and vibration reduction structures respectively. There are two second gaps 36, and the two second gaps 36 belong to the two energy storage and vibration reduction structures respectively. Of course, the division of the energy storage and vibration reduction structures can be changed according to actual conditions, for example, Figures 6 to 8 In the case shown, it can also be considered that the two energy storage and vibration reduction structures share the driven stopper 331; Figures 1 to 4 As shown in the situation, there are 6 active stops 321, 6 driven stops 331, 6 first gaps 35, and 6 second gaps 36, wherein the energy storage and vibration reduction structure includes two active stops 321, one driven stop 331, one first gap 35, and one second gap 36. There are 6 energy storage and vibration reduction structures in total, and adjacent energy storage and vibration reduction structures share one active stop 321.

[0088] In some embodiments, the forward rotation movement stroke of the active rotating member 32 includes a forward acceleration stage and a forward deceleration stage, and the reverse rotation movement stroke includes a reverse acceleration stage and a reverse deceleration stage, wherein the active rotating member 32 rotates in a forward acceleration stage and in a forward deceleration stage; rotates in a reverse acceleration stage and in a reverse deceleration stage.

[0089] In this embodiment, forward and reverse are only used to express the two rotation directions of the rotating part (such as clockwise and counterclockwise, where either clockwise is the forward direction or counterclockwise is the forward direction). The forward and reverse directions of the two rotation directions are relative, and it is not limited to one rotation reverse direction being the forward direction and the other rotation reverse direction being the reverse direction.

[0090] In some embodiments, the active rotating member 32 can transmit the force driving the driven rotating member 33 to rotate forward and reverse through the first elastic member 341 and the second elastic member 342. The first elastic member 341 is used to store potential energy when the active rotating member 32 is in the forward starting and / or reverse deceleration stage and / or reverse acceleration stage, and release the potential energy when the active rotating member 32 is in the forward deceleration stage and / or forward acceleration stage; the second elastic member 342 is used to store potential energy when the active rotating member 32 is in the reverse starting and / or forward deceleration stage and / or forward acceleration stage, and release the potential energy when the active rotating member 32 is in the reverse deceleration stage and / or reverse acceleration stage.

[0091] The forward start refers to the first forward acceleration of the active rotating part when the ultrasonic equipment is stopped, and the reverse start refers to the first reverse acceleration of the active rotating part when the ultrasonic equipment is stopped.

[0092] Since the first elastic member and the second elastic member are always in a compressed state in the present application, the elastic potential energy of the corresponding elastic member in the present application stores potential energy at a certain stage of the active rotating member, which means that the elastic potential energy of the elastic member at a certain stage of the active rotating member increases. The elastic potential energy of the elastic member releases potential energy at a certain stage of the active rotating member, which means that the elastic potential energy of the elastic member at a certain stage of the active rotating member decreases.

[0093] The first elastic member 341 can release potential energy when the active rotating member 32 is in the forward acceleration stage to assist the driven rotating member 33 in forward rotation. The second elastic member 342 can release potential energy when the active rotating member 32 is in the reverse acceleration stage to assist the driven rotating member 33 in reverse rotation.

[0094] Specifically, during forward rotation, the active rotating member 32 can exert a force on the first elastic member 341 through the active stopping portion 321, the first elastic member 341 is further compressed, and the first elastic member 341 transfers the force to the driven stopping portion 331, thereby causing the driven rotating member 33 to rotate in the forward direction.

[0095] When the transducer driving mechanism 3 drives the transducer 2 to swing back and forth, the driving motor 31 drives the active rotating member 32 to rotate, and the active rotating member 32 drives the driven rotating member 33 to rotate forward by further squeezing the first elastic member 341, and drives the driven rotating member 33 to rotate reversely by further squeezing the second elastic member 342. The first elastic member 341 and the second elastic member 342 store energy through elastic deformation, thereby reducing the mechanical impact between the active rotating member 32 and the driven rotating member 33, thereby reducing the vibration noise caused by the kinetic energy impact in the ultrasonic probe. In addition, since the first elastic member 341 and the second elastic member 342 are always in a compressed state, they are always in contact with the active rotating member 32 and the driven rotating member 33. When the active rotating member 32 and the driven rotating member 33 move relative to each other, they will not hit the elastic member 34, further reducing the noise in the probe.

[0096] Since the first elastic member 341 can release potential energy to assist the driven rotating member 33 in forward rotation during the forward acceleration phase of the active rotating member 32, and the second elastic member can release potential energy to assist the driven rotating member 33 in reverse rotation during the reverse acceleration phase of the active rotating member 32, the potential energy of the first elastic member 341 and the second elastic member 342 is fully utilized, thereby reducing the performance requirements for the drive motor 31.

[0097] The driving rotating member 32 and the driven rotating member 33 can adopt any feasible transmission mode: for example, one of the driving rotating member 32 and the driven rotating member 33 is a transmission shaft and the other is a wheel, please refer to Figures 3 to 7 The specific structure will be described in detail below; for another example, the active rotating member 32 and the driven rotating member 33 are both transmission shafts. At this time, the active stop portion 321 is arranged at the shaft end of the active rotating member 32, and the driven stop portion 331 is arranged at the shaft end of the driven rotating member 33, and the active rotating member 32 is coaxial with the driven rotating member 33; for another example, the active rotating member 32 is a driving wheel, and the driven rotating member 33 is a driven wheel, the driving wheel and the driven wheel are arranged coaxially, the active stop portion 321 is on the side of the driving wheel toward the driven wheel, and the driven stop portion 331 is on the side of the driven wheel toward the driving wheel.

[0098] Further, in one embodiment, please refer to Fig. 9 The forward rotation movement of the active rotating member 32 also includes a forward stable movement stage, and the forward acceleration stage, the forward stable movement stage and the forward deceleration stage are connected in sequence. The reverse movement of the active rotating member 32 also includes a reverse stable movement stage, and the reverse acceleration stage, the reverse stable movement stage and the reverse deceleration stage are connected in sequence. The first elastic member 341 maintains potential energy in the forward stable movement stage; the second elastic member 342 maintains potential energy in the reverse stable movement stage.

[0099] When the active rotating member 32 works forward and reverse, the forward acceleration stage, the forward stable motion stage, the forward deceleration stage, the reverse acceleration stage, the reverse stable motion stage and the reverse deceleration stage are connected in sequence and cycled. The description of the above stages in this application is for the reciprocating swing state of the transducer 2 in the ultrasonic probe when it is working. In addition to the ultrasonic probe working state, the active rotating member 32 also has forward start, reverse start, forward stop and reverse stop states. Forward start and reverse start have been introduced in the above embodiment, that is, the first start of the active rotating member. Forward stop and reverse stop are the deceleration of the active rotating member 32 to the stop state when the ultrasonic device stops running.

[0100] Further, in one embodiment, please refer to Figures 4 to 5 In an energy storage and vibration reduction structure, at least one of the active stopper 321 and the driven stopper 331 is more than two in number, and the active stopper 321 and the driven stopper 331 are arranged alternately in the rotation direction of the active rotating member 32, so that one driven stopper 331 is between two adjacent active stoppers 321 and / or one active stopper 321 is between two adjacent driven stoppers 331. The staggered arrangement can reduce the number of stoppers and simplify the structure. In some other embodiments, in addition to the staggered arrangement of the active stopper 321 and the driven stopper 331 in an energy storage and vibration reduction structure, two driven stoppers 331 can be arranged between two active stoppers 321. In this case, the elastic member 34 is arranged only between the active stopper 321 and the driven stopper 331.

[0101] Specifically, in one embodiment, the number of active stoppers 321 is the same as the number of passive stoppers 331, any passive stopper 331 is located between two adjacent active stoppers 321, and any active stopper 321 is located between two adjacent passive stoppers 331. Figures 3 to 5 , the number of active stoppers 321 is 6, and the number of driven stoppers is 6. In one embodiment, please refer to Figures 5 to 8 The number of active stopping parts 321 is 2, and the number of driven stopping parts 331 is 2.

[0102] Further, in one embodiment, please refer to Figures 4 to 8, the number of energy storage and vibration reduction structures is more than two, and each energy storage and vibration reduction structure is arranged rotationally symmetrically or centrally symmetrically with the rotation axis of the active rotating member 32 as the center line. In this way, the active rotating member 32 and the driven rotating member 33 can be subjected to more balanced forces and more stable during operation. In some other embodiments, the number of energy storage and vibration reduction structures can also be one. In some other embodiments, when the number of energy storage and vibration reduction structures is two, the two energy storage and vibration reduction structures can also be asymmetrically designed. For example, the distances between the two energy storage and vibration reduction structures and the rotation axis of the active rotating member 32 are different, and the structures of the two energy storage and vibration reduction structures are asymmetric. The formation method of the energy storage and vibration reduction structure has been introduced in the above embodiments and will not be repeated here.

[0103] Please refer to Fig. 9 In one embodiment, taking two active stoppers 321 and two driven stoppers 331 as an example, the motion states of the active rotating member 32 and the driven rotating member 33 are described in detail:

[0104] Before the ultrasonic probe is started, the transducer drive mechanism 3 is not started. At this time, the first elastic member 341 and the second elastic member 342 are in an initial compression state, and the compression amount of the first elastic member 341 and the second elastic member 342 is X. The ultrasonic probe is started, the transducer drive mechanism 3 starts to work, and the active rotating member 32 starts to start forward under the action of the drive motor 31. The active rotating member 32 drives the driven rotating member 33 to rotate forward. At this time, the active stopper 321 further compresses the first elastic member 341, and the first elastic member 341 stores energy until the speed of the active rotating member 32 reaches the requirement. The active rotating member 32 runs stably, and the driven rotating member 33 also runs stably. The ultrasonic probe enters the working state and starts to perform ultrasonic detection on the object to be tested.

[0105] When the ultrasonic probe enters the working state and the active rotating part 32 is in the forward stable motion stage, the compression amount of the first elastic part 341 is X+a, and the active rotating part 32 drives the driven rotating part 33 to rotate forward stably. At this time, the active rotating part 32 and the driven rotating part 33 have the same rotation speed, and the second elastic part 342 is compressed by Xa. After the forward stable motion stage ends, the active rotating part 32 enters the forward deceleration stage.

[0106] The speed of the active rotating member 32 decreases during the positive deceleration stage, and the driven rotating member 33 rotates relative to the active rotating member 32 due to inertia, further compressing the second elastic member 342, so that the second elastic member 342 stores energy. In this process, the compression amount of the first elastic member 341 decreases and the potential energy decreases, and the compression amount of the second elastic member 342 increases and the potential energy increases. At a certain moment during the change of the compression amount of the first elastic member 341 and the second elastic member 342, the first elastic member 341 and the second elastic member 342 are both in the initial compression state, and the compression amount of the first elastic member 341 and the second elastic member 342 are both X. The active rotating member 32 continues to decelerate in the positive direction until the speed of the active rotating member 32 decreases to zero, the speed of the driven rotating member 33 also decreases to zero, the compression amount of the second elastic member 342 increases to X+b, and the compression amount of the first elastic member 341 decreases to Xb, where b is greater than a.

[0107] After the speed of the active rotating member 32 decreases to zero and the speed of the driven rotating member 33 also decreases to zero, the active rotating member 32 enters the reverse acceleration stage, at which time the active rotating member 32 begins to accelerate in the reverse direction. In the reverse acceleration stage, the compression amount of the second elastic member 342 decreases, the potential energy is released, and the compression amount of the first elastic member 341 increases, storing the potential energy. The second elastic member 342 applies a force to the driven rotating member 33 to accelerate the driven rotating member 33 in the reverse direction. Until the compression amount of the second elastic member decreases from X+b to X+a, and the compression amount of the first elastic member 341 increases from Xb to Xa, the active rotating member 32 enters the reverse stable motion stage,

[0108] After the active rotating member 32 enters the reverse stable motion stage, the compression amount of the first elastic member 341 and the second elastic member 342 remains unchanged. The active rotating member 32 drives the driven rotating member 33 to rotate reversely and stably, and the active rotating member 32 and the driven rotating member 33 rotate at the same speed.

[0109] After the reverse stable motion stage is over, the active rotating member 32 enters the reverse deceleration stage, the reverse motion speed of the active rotating member 32 decreases, and the driven rotating member 33 moves relative to the active rotating member 32 due to inertia, squeezing the first elastic member 341, the first elastic member 341 stores energy, and the reverse motion speed of the driven rotating member 33 also decreases. The compression amount of the first elastic member 341 increases and the potential energy increases, and the compression amount of the second elastic member 342 decreases and the potential energy decreases. At a certain moment, the first elastic member 341 and the second elastic member 342 are both in the initial compression state, and the compression amount of the first elastic member 341 and the second elastic member 342 are both X. The active rotating member 32 continues to reversely decelerate until the speed of the active rotating member 32 decreases to zero, the speed of the driven rotating member 33 also decreases to zero, the compression amount of the first elastic member 341 increases to X+b, and the compression amount of the second elastic member 342 decreases to Xb, where b is greater than a.

[0110] Then the active rotating member 32 enters the forward acceleration stage, at which time the active rotating member 32 begins to accelerate in the forward direction. In the forward acceleration stage, the potential energy of the first elastic member 341 is released, the compression amount is reduced, the potential energy of the second elastic member 342 is increased, the compression amount is increased, and the first elastic member 341 acts on the driven rotating member 33 to accelerate the driven rotating member 33 in the forward direction until the compression amount of the first elastic member is reduced from X+b to X+a, and the compression amount of the second elastic member 342 is increased from Xb to Xa, and the active rotating member 32 enters the forward stable movement stage.

[0111] Based on the above analysis, the first elastic member 341 stores potential energy when the active rotating member 32 is in the forward starting, reverse deceleration stage and reverse acceleration stage, and releases potential energy when the active rotating member 32 is in the forward deceleration stage and forward acceleration stage; the second elastic member 342 stores potential energy when the active rotating member 32 is in the reverse starting, forward deceleration stage and forward acceleration stage, and releases potential energy when the active rotating member 32 is in the reverse deceleration stage and reverse acceleration stage.

[0112] After the active rotating member 32 enters the forward stable motion stage, the compression amount of the first elastic member 341 and the second elastic member 342 remains unchanged. The active rotating member 32 drives the driven rotating member 33 to rotate forward stably, and the active rotating member 32 and the driven rotating member 33 rotate at the same speed.

[0113] The active rotating member 32 cycles sequentially through the forward stable motion stage, the forward deceleration stage, the reverse acceleration stage, the reverse stable motion stage, the reverse deceleration stage and the forward acceleration stage.

[0114] It should be noted that, during the forward stable stage and the reverse stable stage, the transducer 2 operates stably, and the active rotating member 32 operates at a speed close to or at a uniform speed. During the forward stable stage and the reverse stable stage, the transducer 2 performs ultrasonic testing on the object to be tested.

[0115] The first elastic member 341 is located between the active stopper 321 and the driven stopper 331, and the second elastic member 342 is also located between the active stopper 321 and the driven stopper 331. However, in the positive stable stage of the active rotating member 32, the active rotating member 32 transmits the force through the first elastic member 341 to drive the driven rotating member 33 to rotate positively, and at this time, the compression amount of the first elastic member 341 is greater than the compression amount of the second elastic member 342. In the reverse stable stage of the active rotating member 32, the active rotating member 32 transmits the force through the second elastic member 342 to drive the driven rotating member 33, and at this time, the compression amount of the first elastic member 341 is less than the compression amount of the second elastic member 342.

[0116] Furthermore, in some embodiments, in order to be able to more accurately control the positions of the active rotating member 32 and the driven rotating member 33, the driving motor 31 includes a motor controller (not shown in the figure), and the transducer driving mechanism 3 includes a first stroke sensor (not shown in the figure) for detecting the rotational position of the active rotating member 32 and a second stroke sensor (not shown in the figure) for detecting the rotational position of the driven rotating member 33, and the first stroke sensor and the second stroke sensor are both communicatively connected to the motor controller.

[0117] When the first stroke sensor detects that the active rotating member 32 rotates forward to the end of the stroke and stops, and the second stroke sensor detects that the driven rotating member 33 rotates forward to the end of the stroke and stops, the motor controller controls the drive motor 31 to drive the active rotating member 32 to start reverse rotation. Similarly, when the first stroke sensor detects that the active rotating member 32 rotates reversely to the end of the stroke and stops, and the second stroke sensor detects that the driven rotating member 33 rotates reversely to the end of the stroke and stops, the motor controller controls the drive motor 31 to drive the active rotating member 32 to start forward rotation. The number of the first stroke sensor and the second stroke sensor can be set as needed, and can be one or any number of more than two. The type of the stroke sensor can be a laser sensor or a rotary encoder.

[0118] The first stroke sensor detects the position of the active rotating member 32 and the second stroke sensor detects the position of the driven rotating member 33, so that the motor controller can control the driving motor 31 according to the state of the rotating member, thereby improving the control accuracy.

[0119] Further, in some embodiments, please refer to Figure 4 and Figure 5 The driving rotating member 32 is a driving wheel 32a, the driven rotating member 33 is a driven rotating shaft 33a, and the driving wheel 32a has a driving wheel center hole 323 (please refer to Figure 5 ), the driven rotating shaft 33a passes through the driving wheel 32a coaxially from the driving wheel center hole 323 and rotates with the driving wheel 32a within a set angle range. The driving wheel 32a and the driven rotating shaft 33a can rotate relative to each other, and the position accuracy of the two is higher during assembly. By passing the driven wheel shaft through the driving wheel 32a, the overall structure is more compact and occupies less space.

[0120] For specific examples, please refer to Figures 1 to 8 , the driving wheel 32a is a gear. In some other embodiments, the driving wheel can also be a pulley or a friction wheel. The driving wheel in the present application is not limited to the power source. The driving wheel in the present application is only relative to the driven rotating shaft and is used to drive the driven rotating shaft to rotate. The driving motor also needs to drive the driving wheel to rotate through other transmission parts. Of course, in some other embodiments, the driving motor can also directly drive the driving wheel to rotate.

[0121] For specific examples, please refer to Figure 4 and Figure 5 The active stopper 321 protrudes along the axial direction of the active rotating member 32 and is arranged around the driven rotating shaft 33a, and the driven stopper 331 is located on the portion of the driven rotating shaft 33a extending from the driving wheel 32a. Since the driven stopper 331 is located on the portion extending from the driven rotating shaft 33a, it is more convenient to operate during processing or installation.

[0122] For some examples, please refer to Figure 4 and Figure 5 A stop groove 322 is formed between adjacent active stop parts 321, and the driven stop part 331 is inserted into the stop groove 322 along the axial direction of the driven rotating shaft 33a. The driven stop part 331 and the bottom of the stop groove 322 are matched in the axial direction of the driven rotating shaft 33a. One end of the driven rotating shaft 33a extends out of the driving wheel 32a, and the other end is matched with the driving wheel 32a. This design facilitates the positioning between the driving wheel 32a and the driven rotating shaft 33a. In some other embodiments, in order to achieve axial positioning of the driving wheel 32a and the driven rotating shaft 33a, a step or a protrusion is set in the center hole of the driving wheel 32a, and a shoulder and a step or a protrusion are set on the driven rotating shaft 33a to position the driven rotating shaft 33a along the axial direction. In some other embodiments, the driven rotating shaft 33a can also be axially positioned with the transducer mounting seat 1, and the driving wheel 32a is also axially positioned with the transducer mounting seat 1. In this case, it is also feasible that the driven rotating shaft 33a and the driving wheel 32a have no positioning matching relationship.

[0123] In one embodiment, please refer to Figure 4 and Figure 5 In some other embodiments, the active stopper 321 and the driven stopper 331 are both convex blocks, and the shape of the convex blocks is a hexahedron. In some other embodiments, the active stopper 321 and the driven stopper 331 can be convex blocks of other feasible shapes, such as triangular prism convex blocks; in some other embodiments, the active stopper 321 can be a groove, and the driven stopper 331 can be a convex block adapted to the groove. In some other embodiments, the arrangement positions of the active stop portion 321 and the driven stop portion 331 can also be any feasible manner, for example, the driven stop portion 331 is on the axial end face of the driven rotating shaft 33a, and the active stop portion 321 is on the inner hole wall of the center hole 323 of the driving wheel; for another example, the driven stop portion 331 is arranged on the outer circumferential surface of the driven rotating shaft 33a, and the active stop portion 321 is on the inner hole wall of the center hole 323 of the driving wheel; for another example, the driving wheel 32a has no center hole, at this time the driving wheel 32a and the driven rotating shaft 33a are coaxially spaced in the axial direction of the driving wheel 32a, the active stop portion 321 is on the wheel end face of the driving wheel 32a, and the driven stop portion 331 is on the axial end face of the driven rotating shaft 33a.

[0124] For some examples, please refer to Figure 4 and Figure 5 The driven rotating member 33 is a driven rotating shaft 33a, which is stopped from rotating with the transducer 2, so that the driven rotating shaft 33a can drive the transducer 2 to swing back and forth. The driven rotating member 33 is a driven rotating shaft 33a that is directly stopped from rotating with the transducer 2, which reduces the influence of the kinetic energy of the transducer 2 on other parts of the driving mechanism.

[0125] For some examples, please refer to Figures 1 to 3 The ultrasonic probe includes a transducer bracket 4, and the transducer 2 is fixed on the transducer bracket 4. The transducer bracket 4 includes a first leg 41 and a second leg 42, and the first leg 41 and the second leg 42 are arranged in an axial direction of the driving wheel 32a at intervals, and the driving wheel 32a is located between the first leg 41 and the second leg 42. The first leg 41 and the driven rotating shaft 33a are stopped from rotating, and the first leg 41 is rotatably assembled on the transducer mounting seat 1 through the driven rotating shaft 33a. The second leg 42 is rotatably assembled on the transducer mounting seat 1; the active stopper 321 is located on the side of the driving wheel 32a facing away from the first leg 41. This arrangement makes the overall structure more compact.

[0126] Specifically, the first support leg 41 is provided with a first support leg shaft hole 411, and the driven rotating shaft 33a passes through the first support leg shaft hole 411. A stopper mounting hole 412 is provided on the hole wall of the first support leg shaft hole 411, and the extension direction of the stopper mounting hole 412 is perpendicular to the first support leg shaft hole 411. A stopper shaft hole 332 corresponding to the stopper mounting hole 412 is provided on the driven rotating shaft 33a. After the driven rotating shaft 33a passes through the first support leg shaft hole 411, the stopper shaft hole 332 is aligned with the stopper mounting hole 412, and the stopper pin is inserted into the stopper mounting hole 412 and the stopper shaft hole 332, so that the first support leg 41 and the driven rotating shaft 33a are stopped.

[0127] The transducer mounting seat 1 is provided with a rotating shaft mounting hole 11 which is rotatably matched with the driven rotating shaft 33a. The driven rotating shaft 33a passes through the rotating shaft mounting hole 11 and is rotatably mounted on the transducer mounting seat 1. The driving wheel 32a is mounted on the driven rotating shaft 33a.

[0128] When the driving wheel 32a rotates, it drives the driven rotating shaft 33a to rotate, and then drives the transducer bracket 4 to rotate.
