[0024] The following describes in detail the implementation manners of the present application. The examples of the implementation manners are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The implementation manners described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0025] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the implementation manners of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of the present application. Obviously, the described implementation manners are only a part of the implementation manners of the present application, rather than all of the implementation manners. Based on the implementation manners in the present application, all other implementation manners obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0026] Please refer to Figure 1 , the implementation manner of the present application provides an ultrasonic detection device. The ultrasonic detection device includes a main body and an ultrasonic probe 1. The ultrasonic probe 1 is connected to the main body, and the ultrasonic probe 1 can detect the abdominal parameters of a patient or a pregnant woman and transmit them to the main body.

[0027] For example, the main body may include a display screen, and the data detected by the ultrasonic probe 1 can be displayed through the display screen. Or, in some other implementation manners, the main body may also refer to a computer.

[0028] Among them, the ultrasonic probe 1 can be connected to the main body through a wire, and the ultrasonic probe 1 can also be wirelessly connected to the main body.

[0029] In some implementation manners, the ultrasonic probe 1 may include a handle housing 11 and a sound window housing 13. The sound window housing 13 can be connected to the handle housing 11.

[0030] For example, the handle housing 11 can be an annular housing, and the interior of the handle housing 11 can be used to install electrical appliances and structural components. One end of the handle housing 11 can be connected to the acoustic window housing 13, and the other end of the handle housing 11 can be used to install electrical wires.

[0031] Please refer to Figures 2 to 4 , in some embodiments, the ultrasonic probe 1 further includes a base 15, a driving member 17, a sound head 19, a belt transmission assembly 21, and a rope transmission assembly 23.

[0032] The driving member 17 is disposed on the base 15, the belt transmission assembly 21 is connected to the driving end of the driving member 17, and the driving member 17 can be used to drive the belt transmission assembly 21 to perform transmission. The rope transmission assembly 23 is disposed on the base 15 and is in transmission connection with the belt transmission assembly 21. The rope transmission assembly 23 is further connected to the sound head 19, and the sound head 19 is rotatably connected to the base 15.

[0033] The belt transmission assembly 21 moves to drive the rope transmission assembly 23 to move. When the rope transmission assembly 23 moves, it drives the sound head 19 to rotate reciprocally through the rope. Thus, in this application, by providing the belt transmission assembly 21 between the driving member 17 and the rope transmission assembly 23, the belt transmission assembly 21 can absorb the impact generated when the driving member 17 starts and stops or when the rotational speed fluctuates, which helps the rope transmission assembly 23 drive the sound head 19 to rotate smoothly, improving the situation where the detection image of the ultrasonic probe 1 shakes or is distorted. In addition, the transmission method of the belt transmission assembly 21 and the rope transmission assembly 23 is relatively simple, without complex debugging and with low noise.

[0034] In some embodiments, the base 15 can be installed inside the handle housing 11 and at least partially exposed outside the handle housing 11. The acoustic window housing 13 can be connected to the base 15 to be connected to the handle housing 11 through the base 15. A sealed accommodation space can be formed between the acoustic window housing 13 and the base 15, and the sound head 19 is rotatably located in the accommodation space.

[0035] The acoustic window housing 13 can be an arc-shaped housing, a semi-circular housing, or a housing of other shapes.

[0036] The acoustic window housing 13 can be snap-connected to the base 15, which helps the acoustic window housing 13 and the base 15 to be stably connected, with a simple connection method and easy production.

[0037] In some embodiments, the accommodation space can be filled with a coupling agent to reduce the air gap, which helps the ultrasonic waves emitted by the sound head 19 to be stably transmitted through the coupling agent.

[0038] In some embodiments, the driving member 17 can be a motor. For example, the driving member 17 can be a stepper motor.

[0039] In some embodiments, along the axial direction of the driving end of the driving member 17, the driving member 17, the belt transmission assembly 21, the rope transmission assembly 23, and the sound head 19 can be sequentially arranged, so that the axis of the driving member 17 can be substantially the same as the length direction of the ultrasonic probe 1, which helps to reduce the size of the handle housing 11 at the position of the driving member 17, facilitates the user's grip, and improves the user experience.

[0040] Among them, the length direction of the ultrasonic probe 1 can be substantially the direction from the handle housing 11 to the sound window housing 13.

[0041] Specifically, the driving member 17 can include a connected driving body and a driving shaft. The driving shaft can be connected to the belt transmission assembly 21, and the driving body can drive the driving shaft to rotate. The direction from the driving body to the driving shaft can be substantially the direction from the handle housing 11 to the sound window housing 13.

[0042] In some embodiments, the belt transmission assembly 21 can include a driving pulley 211, a driven pulley 213, and a synchronous belt 215. The synchronous belt 215 can be wound around the outer peripheral surfaces of the driving pulley 211 and the driven pulley 213. The driving pulley 211 can be connected to the driving end of the driving member 17. The driving member 17 can drive the driving pulley 211 to rotate through the driving end. When the driving pulley 211 rotates, it drives the driven pulley 213 to rotate through the synchronous belt 215. When the driven pulley 213 rotates, it drives the rope transmission assembly 23 to transmit power to drive the sound head 19 to rotate reciprocally.

[0043] In some embodiments, the size of the driven pulley 213 can be larger than that of the driving pulley 211, so as to perform speed reduction, which helps to prevent the rotation speed of the sound head 19 from being too fast.

[0044] In some embodiments, at least one of the driving pulley 211 and the driven pulley 213 can adopt a gear structure to increase the friction between the driving pulley 211 or the driven pulley 213 and the synchronous belt 215, which helps the sound head 19 to rotate stably and improves the situation where the detection image of the ultrasonic probe 1 shakes or is distorted.

[0045] In some embodiments, the rope transmission assembly 23 can be located in the accommodating space, which helps to reduce the interference between the ropes in the rope transmission assembly 23 and other structures.

[0046] In some embodiments, the rope transmission assembly 23 can include a rope driving wheel 231, a first rope 233, a second rope 235, and a sound head driving wheel 237.

[0047] The driving pulley 211 of the belt drive assembly 21 can be connected to the driving end of the driving member 17. The rope driving wheel 231 and the driven pulley 213 of the belt drive assembly 21 can be coaxially connected. Thus, when the driven pulley 213 rotates, it can drive the rope driving wheel 231 to rotate synchronously.

[0048] One end of the first rope 233 and one end of the second rope 235 can both be connected to the rope driving wheel 231. The other end of the first rope 233 and the other end of the second rope 235 can both be connected to the sound head driving wheel 237. The sound head driving wheel 237 is connected to the sound head 19 and rotates synchronously. In this way, when the driven pulley 213 drives the rope driving wheel 231 to rotate, it can drive the first rope 233 or the second rope 235 to wind around the outer circumference of the rope driving wheel 231, thereby driving the sound head driving wheel 237 to rotate, and the sound head 19 then rotates synchronously with the sound head driving wheel 237.

[0049] Specifically, the first rope 233 includes a first end and a second end, and the second rope 235 includes a third end and a fourth end. The first end of the first rope 233 and the third end of the second rope 235 are both connected to the rope driving wheel 231. The second end of the first rope 233 and the fourth end of the second rope 235 are both connected to the sound head driving wheel 237.

[0050] When the rope driving wheel 231 rotates in the first direction, the first end of the first rope 233 can wind around the outer circumference of the rope driving wheel 231. It can be understood that during the winding process of the first rope 233, the second end of the first rope 233 synchronously pulls the sound head driving wheel 237 to rotate, and at the same time the sound head 19 rotates with the sound head driving wheel 237. When the rope driving wheel 231 rotates in the second direction, the third end of the second rope 235 winds around the outer circumference of the rope driving wheel 231. It can be understood that during the winding process of the second rope 235, the fourth end of the second rope 235 synchronously pulls the sound head driving wheel 237 to rotate, and at the same time the sound head 19 rotates with the sound head driving wheel 237. Among them, the first direction and the second direction can be opposite.

[0051] It can be understood that the first rope 233 can pull the sound head 19 to rotate in the third direction, and the second rope 235 can pull the sound head 19 to rotate in the fourth direction. The third direction and the fourth direction can be opposite.

[0052] In some embodiments, the ultrasonic probe 1 may further include a connecting shaft. The connecting shaft is rotatably connected to the base 15 and is located in the accommodating space. For example, both ends of the connecting shaft are rotatably connected to the base 15 through bearings.

[0053] The connecting shaft and the acoustic head driving wheel 237 can be coaxially connected and can rotate synchronously. In some other embodiments, the connecting shaft and the acoustic head driving wheel 237 can also adopt an integrally formed structure to reduce the number of components and lower the manufacturing cost.

[0054] It should be noted that the above connection relationship between the connecting shaft and the acoustic head driving wheel 237 is only taken as an example for easy understanding, and other connection methods can also be adopted between the connecting shaft and the acoustic head driving wheel 237.

[0055] The acoustic head 19 and the acoustic head driving wheel 237 can be distributed on the upper and lower sides along the axial direction of the connecting shaft, which also helps to reduce the axial size of the ultrasonic probe 1 and improve the holding feel.

[0056] The acoustic head 19 and the acoustic head driving wheel 237 can be fixedly connected. For example, the acoustic head 19 and the acoustic head driving wheel 237 can be connected by fixing parts, bonding, clamping or other fixed connection methods. Among them, the fixing parts can be screws, bolts, rivets or other fixed structures.

[0057] When the first rope 233 or the second rope 235 drives the acoustic head driving wheel 237 to rotate, the acoustic head driving wheel 237, the connecting shaft and the acoustic head 19 can rotate synchronously.

[0058] In some embodiments, the outer peripheral surface of the rope driving wheel 231 can be provided with a spiral groove, so that it is convenient for the first rope 233 and the second rope 235 to be wound in the spiral groove, which helps to reduce the situation that the first rope 233 and the second rope 235 break away from the rope driving wheel 231 during the winding process and helps the acoustic head 19 to rotate more stably.

[0059] For example, the rope driving wheel 231 can adopt a cylindrical screw rod, or the rope driving wheel 231 can also adopt other shaped structures.

[0060] Please refer to Figures 3 to Figure 5 , in some embodiments, the rope transmission assembly 23 can further include a first reversing wheel 239 and a second reversing wheel 241. The first reversing wheel 239 can be used to change the direction of the first rope 233, and the second reversing wheel 241 can change the direction of the second rope 235, so that the first rope 233 and the second rope 235 can better connect the acoustic head driving wheel 237 to pull the transmission wheel of the acoustic head 19 to rotate.

[0061] Among them, the rope driving wheel 231, the first reversing wheel 239 and the second reversing wheel 241 can be distributed in a triangle, and the axial directions of the first reversing wheel 239 and the second reversing wheel 241 can be the same as the axial direction of the rope driving wheel 231, so as to facilitate the arrangement of the first rope 233 and the second rope 235.

[0062] For example, the rope driving wheel 231 has opposite first and second sides. The first reversing wheel 239 is arranged on the first side, and the second reversing wheel 241 is arranged on the second side. The first rope 233 can be connected to the first side of the rope driving wheel 231, or the first rope 233 can be led out from the first side of the rope driving wheel 231. The first rope 233 is then wound around the side of the first reversing wheel 239 facing away from the second reversing wheel 241, and then the first rope 233 is connected to the sound head driving wheel 237. Similarly, the second rope 235 can be connected to the second side of the rope driving wheel 231, or the second rope 235 can be led out from the second side of the rope driving wheel 231. The second rope 235 is then wound around the side of the second reversing wheel 241 facing away from the first reversing wheel 239, and then the second rope 235 is connected to the sound head driving wheel 237.

[0063] The first rope 233 can be wound around the first reversing wheel 239 and the sound head driving wheel 237.

[0064] For example, the sound head driving wheel 237 can be generally in a semi-circular structure. The axial direction of the sound head driving wheel 237 can be set at an angle with the axial direction of the rope driving wheel 231. For example, the axial direction of the sound head driving wheel 237 can be perpendicular to the axial direction of the rope driving wheel 231. Along the direction from the first reversing wheel 239 to the second reversing wheel 241, the sound head driving wheel 237 and the rope driving wheel 231 are respectively located on the left and right sides of this direction. The sound head driving wheel 237 can also be located above the outer circumferences of the first reversing wheel 239 and the second reversing wheel 241, so that the first rope 233 and the second rope 235 can be stably wound around the sound head driving wheel 237. Specifically, the first rope 233 can be tangentially connected to the sound head driving wheel 237, and the second rope 235 can also be tangentially connected to the sound head driving wheel 237.

[0065] Among them, the axial direction of the sound head driving wheel 237 can be perpendicular to the axial direction of the rope driving wheel 231, which can mean that the axial direction of the sound head driving wheel 237 and the axial direction of the rope driving wheel 231 are approximately at a 90-degree angle. However, it can be understood that due to the influence of installation errors, manufacturing errors, etc., the angle between the axial direction of the sound head driving wheel 237 and the axial direction of the rope driving wheel 231 can also deviate around 90 degrees, such as 88 degrees, 89 degrees, 91 degrees, 92 degrees, etc.

[0066] Above the outer circumferences of the first reversing wheel 239 and the second reversing wheel 241 can be generally the side of the first reversing wheel 239 and the second reversing wheel 241 facing away from the driving member 17.

[0067] In some embodiments, the second rope 235 can be wound around the second reversing wheel 241 and the sound head driving wheel 237. The way the second rope 235 is wound around the sound head driving wheel 237 can be generally the same as the way the first rope 233 is wound around the sound head driving wheel 237, and will not be elaborated here.

[0068] In some embodiments, the rope drive assembly 23 may further include an elastic member 243. The elastic member 243 may be located between the first reversing wheel 239 and the second reversing wheel 241, and adjust the distance between the first reversing wheel 239 and the second reversing wheel 241, so that the elastic member 243 can tension the first rope 233 and the second rope 235, which helps the sound head 19 rotate more stably.

[0069] Specifically, during installation, the positions of the first reversing wheel 239 and the second reversing wheel 241 can be adjusted so that the elastic member 243 is in a compressed state. At this time, the elastic member 243 has an elastic restoring force. When the first rope 233 becomes longer or loose due to aging or stretching, the pressure exerted by the first reversing wheel 239 on the elastic member 243 becomes smaller, and the elastic member 243 pushes the first reversing wheel 239 away from the second reversing wheel 241, making the first rope 233 taut. Similarly, the second rope 235 can also be tensioned in the same way and will not be elaborated here.

[0070] Among them, the elastic member 243 can be a spring. In some other embodiments, the elastic member 243 can also be made of other elastic materials, such as elastic rubber, elastic silica gel or others.

[0071] In some embodiments, the rope drive assembly 23 may further include a sliding member 245. The base 15 may be provided with a chute 151, and the first reversing wheel 239 and the second reversing wheel 241 may be located at both ends of the chute 151 respectively. The sliding member 245 is slidably located in the chute 151, the elastic member 243 may be located in the chute 151, one end of the elastic member 243 abuts against the sliding member 245, and one of the first reversing wheel 239 and the second reversing wheel 241 is connected to the sliding member 245, and the other is connected to the base 15. In this way, the inner wall of the chute 151 can stably support the elastic member 243, so that the elastic member 243 can work more stably, reducing the situation of failure and deformation of the elastic member 243 and extending the service life of the elastic member 243.

[0072] In addition, in this embodiment, since one of the first reversing wheel 239 and the second reversing wheel 241 is fixed on the base 15 and the other is fixed on the sliding member 245, it is convenient for assembly, reducing the debugging of the distance between the first reversing wheel 239 and the second reversing wheel 241 and improving the assembly speed.

[0073] For example, the first reversing wheel 239 can be fixed to the sliding member 245, and the second reversing wheel 241 can be fixed to the base 15.

[0074] In some embodiments, the slider 245 may be provided with an installation groove, the installation groove may communicate with the sliding groove 151, and the elastic member 243 may be inserted into the installation groove, which helps the elastic member 243 to work more stably and reduces the situation where the elastic member 243 disengages from the sliding groove 151.

[0075] In some embodiments, the rope drive assembly 23 may further include a first tensioning shaft 247 and a second tensioning shaft 249. The first tensioning shaft 247 is rotatably connected to the sound head drive wheel 237. The other end of the first rope 233 is connected to the sound head drive wheel 237 through the first tensioning shaft 247, that is, the second end of the first rope 233 is connected to the sound head drive wheel 237. In this way, the first tensioning shaft 247 can replace the connection between the sound head drive wheel 237 and the first rope 233, thereby reducing the friction between the first rope 233 and the sound head drive wheel 237, helping to extend the service life of the sound head drive wheel 237, facilitating the repair and replacement of the first tensioning shaft 247, and also helping to reduce the maintenance cost.

[0076] Similarly, the second tensioning shaft 249 is rotatably connected to the sound head drive wheel 237. The other end of the second rope 235 is connected to the sound head drive wheel 237 through the second tensioning shaft 249, that is, the fourth end of the second rope 235 is connected to the sound head drive wheel 237. Its beneficial effects are roughly the same as those of the first tensioning shaft 247 described above and will not be elaborated here.

[0077] In some embodiments, the first tensioning shaft 247 and the second tensioning shaft 249 may be symmetrically distributed, so that the rotation position of the sound head 19 can be more accurate, improving the user experience.

[0078] In some embodiments, the first rope 233 may be wound around the first tensioning shaft 247, and the second rope 235 may be wound around the second tensioning shaft 249, so as to better tension the first rope 233 and the second rope 235 and reduce the precision requirements for the lengths of the first rope 233 and the second rope 235. In addition, the first rope 233 and the second rope 235 can be stored, reducing the interference between the first rope 233 and the second rope 235 and other structural components due to their non-tensioned states.

[0079] Specifically, during installation, the overlong first rope 233 can be wound around the first tensioning shaft 247, and the overlong second rope 235 can be wound around the second tensioning shaft 249, so as to tension the first rope 233 and the second rope 235.

[0080] In some embodiments, the first tensioning shaft 247 and the second tensioning shaft 249 both have locking positions relative to the head driving wheel 237, so that the first tensioning shaft 247 and the second tensioning shaft 249 can be fixed during assembly, which helps to avoid the situation that the first tensioning shaft 247 and the second tensioning shaft 249 rotate randomly.

[0081] It can be understood that the first tensioning shaft 247 and the second tensioning shaft 249 can be fixed in the locking position in various ways. For example, taking the first tensioning shaft 247 as an example, the first tensioning shaft 247 can be bonded to the head driving wheel 237, or the first tensioning shaft 247 can be snap-fitted to the head driving wheel 237, or other structural members can also be used to fix the first tensioning shaft 247 to the head driving wheel 237, and so on. Similarly, the second tensioning shaft 249 can also be fixed to the head driving wheel 237 in the same way as the first tensioning shaft 247, which will not be elaborated here.

[0082] In some embodiments, the rope transmission assembly 23 may further include a first locking member 251 and a second locking member 253. The first locking member 251 can be connected to the head driving wheel 237 and fix the first tensioning shaft 247 in the locking position, and the second locking member 253 can be connected to the head driving wheel 237 and fix the second tensioning shaft 249 in the locking position.

[0083] The head driving wheel 237 may be provided with a first through hole 2371, a second through hole 2373, a first opening groove 2375 and a second opening groove 2377, wherein the first through hole 2371 and the second through hole 2373 may be symmetrically distributed, and the first opening groove 2375 and the second opening groove 2377 may also be symmetrically distributed.

[0084] The first opening groove 2375 may communicate with the first through hole 2371. The first tensioning shaft 247 may be installed in the first through hole 2371. The first locking member 251 is connected to the head driving wheel 237. The first locking member 251 can be used to adjust the groove width of the first opening groove 2375, so as to change the diameter of the first through hole 2371, or cause the first through hole 2371 to deform, so that the hole wall of the first through hole 2371 can squeeze the first tensioning shaft 247, thereby fixing the first tensioning shaft 247 in the first through hole 2371.

[0085] For example, the first locking member 251 can be a screw, a bolt, a rivet or other fixing member. The first opening groove 2375 divides the head driving wheel 237 into upper and lower parts. The first locking member 251 can be inserted into the upper and lower parts to narrow the groove width of the first opening groove 2375, so as to change the diameter of the first through hole 2371, or cause the first through hole 2371 to deform.

[0086] Similarly, the second opening slot 2377 can communicate with the second through hole 2373. The second tensioning shaft 249 is installed in the second through hole 2373. The second locking member 253 is connected to the sound head driving wheel 237. The second locking member 253 can be used to adjust the slot width of the second opening slot 2377. For the specific locking method, reference can be made to the locking method of the first locking member 251, which will not be elaborated here.

[0087] In the ultrasonic probe 1 and the ultrasonic detection device provided by the embodiments of the present application, the driving member 17 is arranged on the base 15. The belt transmission assembly 21 is connected to the driving end of the driving member 17. The driving member 17 can be used to drive the belt transmission assembly 21 to perform transmission. The rope transmission assembly 23 is arranged on the base 15 and is in transmission connection with the belt transmission assembly 21. The rope transmission assembly 23 is also connected to the sound head 19. The sound head 19 is rotatably connected to the base 15. The belt transmission assembly 21 moves to drive the rope transmission assembly 23 to move. The rope transmission assembly 23 moves to drive the sound head 19 to rotate reciprocally through the rope. In this way, by arranging the belt transmission assembly 21 between the driving member 17 and the rope transmission assembly 23 in the present application, the belt transmission assembly 21 can absorb the impact generated when the driving member 17 starts and stops or when the rotational speed fluctuates, which helps the rope transmission assembly 23 drive the sound head 19 to rotate smoothly, improving the situation that the detection image of the ultrasonic probe 1 shakes or is distorted. In addition, the transmission methods of the belt transmission assembly 21 and the rope transmission assembly 23 are relatively simple, without complex debugging and with low noise.
