Description

Technical Field

[0001] This application relates to the field of ultrasonic probes, and more specifically, to a device for testing the abrasion resistance of an ultrasonic probe's acoustic lens. Background Technology

[0002] An ultrasonic probe acoustic lens is an acoustic element that uses the difference in the propagation speed of sound waves in different media to control the direction of sound wave propagation through the principle of refraction. The acoustic lens of an ultrasonic probe needs to be tested for wear resistance. In the existing technology, a simulated skin layer is used to rub the outer surface of the acoustic lens a certain number of times before the acoustic performance of the acoustic lens is tested. The performance changes before and after the test are compared to evaluate the wear resistance.

[0003] However, the existing ultrasonic probe acoustic lens abrasion resistance testing device still has the following shortcomings in use: When rubbing the acoustic lens, the existing ultrasonic probe acoustic lens abrasion resistance testing device drives the imitation skin layer to move back and forth on the outer surface of the acoustic lens through the driving device. However, the existing ultrasonic probe acoustic lens abrasion resistance testing device can only rub the outer surface of the acoustic lens back and forth, and cannot rub the outer surface of the acoustic lens unidirectionally. It cannot detect the different effects of back-and-forth friction and unidirectional friction on the acoustic lens. Utility Model Content

[0004] To overcome the above shortcomings, this application provides an ultrasonic probe acoustic lens wear resistance testing device, which aims to improve the existing ultrasonic probe acoustic lens wear resistance testing device, which can only perform reciprocating friction on the outer surface of the acoustic lens, but cannot perform unidirectional friction on the outer surface of the acoustic lens, and cannot detect the different effects of reciprocating friction and unidirectional friction on the acoustic lens.

[0005] This application provides an ultrasonic probe acoustic lens wear resistance testing device, including a worktable and an ultrasonic probe body. The ultrasonic probe body includes an acoustic lens body. A unidirectional friction mechanism for rubbing the acoustic lens body in a single direction is provided above the worktable, and a reciprocating friction mechanism for rubbing the acoustic lens body back and forth is provided above the worktable. The unidirectional friction mechanism includes a vertical plate connected to the top of the workbench. A first sliding groove is provided on one side of the vertical plate. A rotating component is rotatably connected inside the vertical plate. A second sliding groove is provided through one side of the rotating component. A protrusion is slidably connected inside the first sliding groove. The protrusion slides inside the second sliding groove.

[0006] In one specific implementation, the other end of the protrusion is connected to a mounting plate, and the bottom of the mounting plate is connected to a faux leather layer.

[0007] In the above implementation process, by setting the mounting plate, the movement of the mounting plate can be controlled to drive the imitation skin layer to move, and the imitation skin layer rubs against the outer surface of the acoustic lens.

[0008] In one specific implementation, two sets of first track components are connected to one side of the vertical plate, and a sliding member is slidably connected to the outer surface of the first track component. A second track component is connected to one side of each of the two sets of sliding members, and the mounting plate slides inside the second track component.

[0009] In the above implementation process, the first track component enables the slider to slide up and down on the outer surface of the first track component, and the second track component enables the mounting plate to slide left and right inside the second track component.

[0010] In one specific implementation, two sets of limiting plates are connected between the two sets of sliding members, and the protrusion slides inside the limiting plates.

[0011] In the above implementation process, the setting of the limiting plate enables the protrusion to move horizontally between the two sets of limiting plates.

[0012] In one specific implementation, a slot is provided on one side of the rotating component, a locking element is movably inserted into the slot, one end of the locking element is connected to a first motor, and a connecting element is connected to the outer surface of the first motor.

[0013] In the above implementation process, by setting the slot, the card can be inserted into the slot. By controlling the output shaft of the first motor to rotate, the card is rotated, causing the rotating part to rotate and the protrusion to slide inside the first sliding groove. When the protrusion moves in the vertical direction with a shorter path in the first sliding groove, the sliding part will slide on the outer surface of the first track, which can drive the imitation leather layer to move up and down. When the protrusion moves in the horizontal direction with a longer path in the first sliding groove, the mounting plate will slide inside the second track, which can drive the imitation leather layer to move horizontally. The movement trajectory of the imitation leather layer is rectangular, which can achieve unidirectional friction on the acoustic lens.

[0014] In one specific implementation, the reciprocating friction mechanism includes a first cavity, which is formed inside the worktable. A second motor is connected to one side of the worktable. The output shaft of the second motor passes through the worktable and is connected to a bidirectional screw. The other end of the bidirectional screw is rotatably connected inside the first cavity.

[0015] In the above implementation process, by setting up a second motor, the output shaft of the second motor can be controlled to rotate, thereby driving the bidirectional screw to rotate inside the first cavity.

[0016] In one specific implementation, the outer surface of the bidirectional screw is threaded with two sets of first threaded seats. One set of first threaded seats is connected to a cylinder at its top, and the other set of first threaded seats is connected to a fixed plate at its top. A telescopic damping rod is connected to one side of the fixed plate, and a moving part is connected to the other end of the telescopic damping rod. A spring is sleeved on the outer surface of the telescopic damping rod.

[0017] In the above implementation process, by setting up a bidirectional screw, the two sets of first threaded seats can be moved when the bidirectional screw rotates. When the acoustic lens needs to perform reciprocating friction, the output end of the cylinder contacts one end of the mounting plate, and the other end of the mounting plate contacts one end of the moving part. By controlling the extension of the output end of the cylinder, the mounting plate is moved inside the second track part, and the spring is compressed at the same time. After the output end of the cylinder is shortened, the spring releases its elastic potential energy and drives the mounting plate to reset, thus realizing the reciprocating friction of the acoustic lens.

[0018] In one specific implementation, the workbench has a second cavity inside, a second screw is rotatably connected inside the second cavity, the other end of the second screw passes through the second cavity and is connected to a second bevel gear, and a first bevel gear is connected to the outer surface of the bidirectional screw, the first bevel gear meshing with the second bevel gear.

[0019] In the above implementation process, by setting the first screw, when the bidirectional screw rotates, it can drive the first bevel gear to rotate, drive the meshing second bevel gear to rotate, and drive the second screw to rotate inside the second cavity.

[0020] In one specific implementation, the outer surface of the second screw is threadedly connected to a second threaded seat, which is connected to the bottom of the connector.

[0021] In the above implementation process, by setting the second screw, the second threaded seat can be moved when the second screw rotates, so that the connecting part moves and drives the first motor to move. When the cylinder and the moving part approach the two ends of the mounting plate, the locking part gradually moves away from the locking slot, which can disconnect the connection between the rotating part and the first motor. During the process of the cylinder driving the mounting plate to move back and forth, the rotating part can follow the rotation.

[0022] In one specific implementation, a fixing clamp is connected to the top of the workbench, and the ultrasonic probe body is fixed inside the fixing clamp.

[0023] In the above implementation process, by setting the fixing clamp, the ultrasonic probe body can be fixed above the worktable, which facilitates the friction of the simulated skin layer on the acoustic lens body. The fixing clamp is existing technology and will not be described in detail here.

[0024] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a unidirectional friction mechanism and a reciprocating friction mechanism, and by controlling the rotation of the output shaft of the first motor to drive the clamp to rotate, the rotating part rotates, causing the protrusion to slide inside the first sliding groove. When the protrusion moves in the vertical direction with a shorter path in the first sliding groove, the sliding part slides on the outer surface of the first track, which can drive the imitation leather layer to move up and down. When the protrusion moves in the horizontal direction with a longer path in the first sliding groove, the mounting plate slides inside the second track, which can drive the imitation leather layer to move horizontally. The movement trajectory of the imitation leather layer is rectangular, which can realize unidirectional friction on the acoustic lens. When the acoustic lens needs to be reciprocated, by controlling... The second motor rotates, driving the bidirectional screw to rotate, which in turn moves the cylinder and the moving component. This causes the output end of the cylinder to contact one end of the mounting plate, and the other end of the mounting plate to contact one end of the moving component. By controlling the extension of the cylinder's output end, the mounting plate moves inside the second track component, while simultaneously compressing the spring. After the cylinder's output end shortens, the spring releases its elastic potential energy, causing the mounting plate to reset. This process enables reciprocating friction on the acoustic lens, thus solving the problem that existing ultrasonic probe acoustic lens abrasion resistance testing devices can only perform reciprocating friction on the outer surface of the acoustic lens, and cannot perform unidirectional friction, thus failing to detect the different effects of reciprocating and unidirectional friction on the acoustic lens.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Please see Figure 1 , Figure 2 and Figure 3 This application provides an ultrasonic probe acoustic lens wear resistance testing device, including a worktable 1 and an ultrasonic probe body 4.

[0030] Please see Figure 1 and Figure 2 The ultrasonic probe body 4 includes an acoustic lens body 6. A one-way friction mechanism 2 for rubbing the acoustic lens body 6 in a single direction is provided above the worktable 1. A reciprocating friction mechanism 3 for rubbing the acoustic lens body 6 back and forth is provided above the worktable 1.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The one-way friction mechanism 2 includes a vertical plate 201, which is connected to the top of the workbench 1. A first sliding groove 205 is provided on one side of the vertical plate 201. A rotating component 207 is rotatably connected inside the vertical plate 201. A second sliding groove 2014 is provided through one side of the rotating component 207. A protrusion 2010 is slidably connected inside the first sliding groove 205. The protrusion 2010 slides inside the second sliding groove 2014.

[0032] In a specific configuration, the other end of the protrusion 2010 is connected to a mounting plate 204, and the bottom of the mounting plate 204 is connected to a faux leather layer 7. By setting the mounting plate 204, the movement of the mounting plate 204 can be controlled to drive the faux leather layer 7 to move, and the faux leather layer 7 rubs against the outer surface of the acoustic lens.

[0033] In a specific configuration, two sets of first track members 206 are connected to one side of the vertical plate 201. Sliding members 2011 are slidably connected to the outer surface of the first track members 206. A second track member 209 is connected to one side of each set of sliding members 2011. The mounting plate 204 slides inside the second track member 209. The first track member 206 allows the sliding member 2011 to slide up and down on the outer surface of the first track member 206. The second track member 209 allows the mounting plate 204 to slide left and right inside the second track member 209.

[0034] In a specific configuration, two sets of limiting plates 208 are connected between the two sets of sliding members 2011. The protrusion 2010 slides inside the limiting plate 208. The limiting plate 208 enables the protrusion 2010 to move horizontally between the two sets of limiting plates 208.

[0035] In a specific configuration, a slot 2013 is provided on one side of the rotating component 207. A retaining element 2012 is movably inserted into the slot 2013. One end of the retaining element 2012 is connected to a first motor 203, and a connecting element 202 is connected to the outer surface of the first motor 203. The slot 2013 allows the retaining element 2012 to be inserted into it. By controlling the output shaft of the first motor 203 to rotate, the retaining element 2012 is driven to rotate, causing the rotating component 207 to rotate, which in turn drives the protrusion 2010. When the protrusion 2010 slides inside the first sliding groove 205 and moves vertically with a shorter path in the first sliding groove 205, the slider 2011 slides on the outer surface of the first track 206, which can drive the imitation leather layer 7 to move up and down. When the protrusion 2010 moves horizontally with a longer path in the first sliding groove 205, the mounting plate 204 slides inside the second track 209, which can drive the imitation leather layer 7 to move horizontally. The movement trajectory of the imitation leather layer 7 is rectangular, which can achieve unidirectional friction on the acoustic lens.

[0036] In a specific configuration, the reciprocating friction mechanism 3 includes a first cavity 301, which is located inside the worktable 1. A second motor 304 is connected to one side of the worktable 1. The output shaft of the second motor 304 passes through the worktable 1 and is connected to a bidirectional screw 303. The other end of the bidirectional screw 303 is rotatably connected inside the first cavity 301. By controlling the output shaft of the second motor 304, the bidirectional screw 303 can be rotated inside the first cavity 301.

[0037] In a specific configuration, the outer surface of the bidirectional screw 303 is threaded with two sets of first threaded seats 305. One set of first threaded seats 305 has a cylinder 308 connected to its top, while the other set has a fixing plate 3011 connected to its top. A telescopic damping rod 3012 is connected to one side of the fixing plate 3011, and a moving part 3014 is connected to the other end of the telescopic damping rod 3012. A spring 3013 is fitted onto the outer surface of the telescopic damping rod 3012. Through the configuration of the bidirectional screw 303, when the bidirectional screw 303 rotates... The cylinder 308 drives the two sets of first threaded seats 305 to move. When the acoustic lens needs to perform reciprocating friction, the output end of the cylinder 308 contacts one end of the mounting plate 204, and the other end of the mounting plate 204 contacts one end of the moving part 3014. By controlling the extension of the output end of the cylinder 308, the mounting plate 204 is driven to move inside the second track part 209. At the same time, the spring 3013 is compressed. After the output end of the cylinder 308 is shortened, the spring 3013 releases its elastic potential energy and drives the mounting plate 204 to reset, thus realizing the reciprocating friction of the acoustic lens.

[0038] In the specific configuration, the workbench 1 has a second cavity 302 inside, and a second screw 306 is rotatably connected inside the second cavity 302. The other end of the second screw 306 passes through the second cavity 302 and is connected to a second bevel gear 3010. A first bevel gear 309 is connected to the outer surface of the bidirectional screw 303. The first bevel gear 309 and the second bevel gear 3010 are meshed and connected. The first screw can drive the first bevel gear 309 to rotate when the bidirectional screw 303 rotates, thereby driving the meshing second bevel gear 3010 to rotate, and driving the second screw 306 to rotate inside the second cavity 302.

[0039] In a specific configuration, the outer surface of the second screw 306 is threaded with a second threaded seat 307, which is connected to the bottom of the connector 202. The second screw 306, when rotating, drives the second threaded seat 307 to move, causing the connector 202 to move and in turn driving the first motor 203 to move. When the cylinder 308 and the moving part 3014 approach the two ends of the mounting plate 204, the locking part 2012 gradually moves away from the locking slot 2013, disconnecting the connection between the rotating part 207 and the first motor 203. During the reciprocating motion of the mounting plate 204 driven by the cylinder 308, the rotating part 207 rotates accordingly.

[0040] In the specific setup, a fixing clamp 5 is connected to the top of the workbench 1, and the ultrasonic probe body 4 is fixed inside the fixing clamp 5. The fixing clamp 5 can fix the ultrasonic probe body 4 above the workbench 1, which facilitates the friction of the imitation skin layer 7 on the acoustic lens body 6. The fixing clamp 5 is existing technology and will not be described in detail here.

[0041] The working principle of this ultrasonic probe acoustic lens abrasion resistance testing device is as follows: When using the ultrasonic probe acoustic lens abrasion resistance testing device, by controlling the output shaft of the first motor 203 to rotate, the clamp 2012 rotates, causing the rotating part 207 to rotate, which in turn causes the protrusion 2010 to slide inside the first sliding groove 205. When the protrusion 2010 moves vertically along a shorter path in the first sliding groove 205, the sliding part 2011 slides on the outer surface of the first track 206, which can drive the imitation skin layer 7 to move up and down. When the protrusion 2010 moves vertically along a longer path in the first sliding groove 205, the sliding part 2011 slides on the outer surface of the first track 206, which can drive the imitation skin layer 7 to move up and down. When moving horizontally, the mounting plate 204 slides inside the second track component 209, driving the imitation leather layer 7 to move horizontally. The movement trajectory of the imitation leather layer 7 is rectangular, enabling unidirectional friction on the acoustic lens. When the acoustic lens needs to be rubbed back and forth, the second motor 304 is controlled to rotate, driving the bidirectional screw 303 to rotate, which in turn drives the cylinder 308 and the moving component 3014 to move. This causes the output end of the cylinder 308 to contact one end of the mounting plate 204, and the other end of the mounting plate 204 to contact one end of the moving component 3014. The output end of the cylinder 308 is then controlled to extend. The cylinder 308 causes the mounting plate 204 to move inside the second track component 209, simultaneously compressing the spring 3013. After the output end of the cylinder 308 shortens, the spring 3013 releases its elastic potential energy, causing the mounting plate 204 to reset. This enables reciprocating friction against the acoustic lens. When the bidirectional screw 303 rotates, it drives the first bevel gear 309 to rotate, which in turn drives the meshing second bevel gear 3010 to rotate. This causes the second screw 306 to rotate inside the second cavity 302, moving the second threaded seat 307 and thus the connecting component 202. This, in turn, moves the first motor 203. When the cylinder 308 and the moving part 3014 approach the two ends of the mounting plate 204, the locking part 2012 gradually moves away from the locking slot 2013, which can disconnect the connection between the rotating part 207 and the first motor 203. During the process of the cylinder 308 driving the mounting plate 204 to move back and forth, the rotating part 207 can rotate accordingly, thereby solving the problem that the existing ultrasonic probe acoustic lens wear resistance testing device can only perform reciprocating friction on the outer surface of the acoustic lens, but cannot perform unidirectional friction on the outer surface of the acoustic lens, and cannot detect the different effects of reciprocating friction and unidirectional friction on the acoustic lens.

[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
