[0002] Sonar technology plays a critical role in many fields such as ocean exploration, underwater monitoring and navigation. Existing sonar mainly focuses on using the propagation characteristics of sound waves in water to detect targets, such as submarines, fish schools, seabed landforms, etc. However, with the continuous expansion and deepening of these application scenarios, higher requirements are placed on the accuracy and comprehensiveness of the information obtained by the sonar system. In the marine environment, depth information is an indispensable and important parameter. Whether it is conducting marine scientific research, understanding the water temperature, salinity, water flow speed and distribution of marine biological communities at different depths, or in terms of navigation safety, determining the exact water depth under the ship to avoid dangers such as running aground on reefs, depth data is extremely important.

[0040] Before describing in detail any embodiment of the present invention, it should be understood that the present invention is not limited in its application to the construction and arrangement details of the components described below or illustrated in the following figures. The present invention can have other embodiments and can be practiced or carried out in various ways.

[0041] Furthermore, on the first aspect, in the disclosure of the present invention, the orientations or positional relationships indicated by terms such as “longitudinal”, “transverse”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore the above terms cannot be understood as limitations on the present invention; on the second aspect, the term “one” should be understood as “at least one” or “one or more”, that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term “one” cannot be understood as a limitation on the quantity.

[0042] With reference to the accompanying drawings of the present invention Figures 1 to 20 A sonar with a pressure sensor according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the sonar includes a sonar body 10 and a pressure sensor 20 installed on the sonar body 10. When the sonar enters the water and the sonar body 10 detects the underwater by emitting and receiving sound wave signals, the pressure sensor 20 can measure the current depth of the sonar by measuring the water pressure, so that the sonar can obtain more accurate and comprehensive data of the detected area.

[0043] Preferably, the sonar body 10 has an assembly groove 101, and the pressure sensor 20 is installed in the assembly groove 101 of the sonar body 10. In this way, the pressure sensor 20 may not protrude from the surface of the sonar body 10, so that when the sonar moves in the water, the pressure sensor 20 will not affect the acoustic performance of the sonar. For example, the pressure sensor 20 will not cause bubbles to be generated in the surrounding environment of the sonar, so that the sound wave signal emitted by the sonar body 10 only needs to pass through one medium (i.e., water) to radiate toward the direction of the detected area, and the reflected sound wave from the detected area only needs to pass through one medium (i.e., water) to be received by the sonar body 10, thereby ensuring the accuracy of the detection result of the sonar on the detected area.

[0044] Reference Figures 1 to 5 , Figure 7 , Figures 9 to 16 The sonar body 10 includes a cabin 11, a watertight terminal 12, a transceiver array assembly 13 and a circuit board assembly 14. The cabin 11 has a cabin cavity 111 and a terminal channel 112, and the terminal channel 112 is connected to the cabin cavity 111. The watertight terminal 12 is watertightly installed in the terminal channel 112 of the cabin 11, one end of the watertight terminal 12 extends to the cabin cavity 111 of the cabin 11 to form the inner end of the watertight terminal 12, and one end of the watertight terminal 12 extends to the outside of the cabin 11 to form the outer end of the watertight terminal 12. The transceiver array assembly 13 is installed in the cabin 11, and the transceiver array assembly 13 closes the cavity of the cabin cavity 111 of the cabin 11, so that the cabin cavity 111 of the cabin 11 forms a watertight environment. The circuit board assembly 14 is installed in the transceiver array assembly 13, and the circuit board assembly 14 is accommodated in the cabin cavity 111 of the cabin body 11, so that the circuit board assembly 14 is maintained in a watertight environment. The inner end of the watertight terminal 12 is connected to the circuit board assembly 14. The assembly groove 101 of the sonar body 10 is formed in the transceiver array assembly 13, so that the pressure sensor 20 is installed in the transceiver array assembly 13. Optionally, in other examples of the sonar of the present invention, the assembly groove 101 of the sonar body 10 can also be formed in the cabin body 11, so that the pressure sensor 20 is installed in the cabin body 11.

[0045] Reference Figure 4 , Figure 5 , Figure 7 , Figures 13 to 16The transceiver array assembly 13 further includes a top cover 131, a vulcanization part 132, a receiving array 133 and a transmitting array 134, wherein the vulcanization part 132 is vulcanized on the top cover 131, and the vulcanization part 132 is combined with the receiving array 133 during the vulcanization process, so that the top cover 131, the vulcanization part 132 and the receiving array 133 are combined into a whole, and the transmitting array 134 is installed on the top cover 131, and the top cover 131 is installed on the cabin 11 and is used to close the cavity opening of the cabin cavity 111. That is to say, in this specific example of the sonar of the present invention, the transmitting array 134 is installed on the top cover 131 after the vulcanization part 132 is formed, which makes the transmitting array 134 detachable. In this way, when the transmitting array 134 is damaged, it is only necessary to replace the new transmitting array 134 to complete the maintenance of the sonar. When the receiving array 133 is damaged, the transmitting array 134 can be reused, thereby avoiding waste and reducing the maintenance cost of the sonar.

[0046] Reference Figure 4 and Figure 5 , the assembly slot 101 of the sonar body 10 is formed in the top cover 131, so in this specific example of the sonar of the present invention, the pressure sensor 20 is installed on the top cover 131. Preferably, the assembly slot 101 of the sonar body 10 is located below the transmitting array 134, so that the pressure sensor 20 is located below the transmitting array 134. In this way, on the one hand, the pressure sensor 20 is hidden by the top cover 131 and the transmitting array 134 to avoid the pressure sensor 20 from being exposed, so as to protect the pressure sensor 20. On the other hand, the arrangement of the pressure sensor 20 will not affect the overall appearance of the sonar, so that the pressure sensor 20 will not affect the acoustic performance of the sonar.

[0047] Preferably, the assembly groove 101 of the sonar body 10 has a receiving groove 1011 and an assembly through hole 1012 extending from the receiving groove 1011 to the lower surface of the top cover 131, and the inner diameter of the assembly through hole 1012 is smaller than the inner diameter of the receiving groove 1011, wherein the pressure sensor 20 includes a sensor body 21 and an assembly column 22 extending downward from the sensor body 21, and the outer diameter of the sensor body 21 is larger than the outer diameter of the assembly through hole 1012 of the sonar body 10. Inner diameter size, wherein after the assembly column 22 of the pressure sensor 20 extends to the bottom of the top cover 131 through the assembly through hole 1012, the sensor body 21 is accommodated in the receiving groove 1011 of the sonar body 10, and the sonar further includes a nut 30, and the nut 30 is screwed on the portion of the assembly column 22 protruding from the bottom of the top cover 131, so that the nut 30 and the sensor body 21 cooperate with each other to install the pressure sensor 20 on the top cover 131.

[0048] The sonar further includes at least one sealing ring 40, which is clamped between the sensor body 21 and the top cover 131, and the sensor body 21 and the top cover 131 clamp and deform the sealing ring 40, so that the sealing ring 40 increases the water tightness of the installation position of the pressure sensor 20 and the top cover 131.

[0049] Preferably, the top cover 131 has a groove 1310, and the bottom of the transmitting array 134 sinks into the groove 1310 of the top cover 131, which is conducive to reducing the height size of the sonar, thereby facilitating the miniaturization of the sonar. After the transmitting array 134 is installed on the top cover 131 in a manner that the bottom of the transmitting array 134 sinks into the groove 1310 of the top cover 131, the sonar body 10 forms a water flow channel 102 between the top cover 131 and the transmitting array 134. After the sonar is immersed in water, the water cup is allowed to reach the pressure sensor 20 through the water flow channel 102 of the sonar body 10, so that the pressure sensor 20 measures the current depth of the sonar by measuring the water pressure.

[0050] Reference Figures 1 to 5 , Figure 7 , Figures 9 to 16The top cover 131 has at least one front plate through hole 1311, which passes through the top and bottom of the top cover 131. The receiving array 133 has at least one front plate 1331. The top of the front plate 1331 extends from the bottom of the top cover 131 to the top through the front plate through hole 1311 of the top cover 131, wherein the vulcanized portion 132 is vulcanized on the top of the top cover 131, and the vulcanized portion 132 wraps the top of the front plate 1331, so that the top cover 131, the vulcanized portion 132 and the receiving array 133 are combined into a whole.

[0051] Furthermore, the top cover 131 has a cover ring 1312 and a baffle 1313, the cover ring 1312 and the baffle 1313 are respectively located at the rear side and the front side of the groove 1310 of the top cover 131, and after the emitting array 134 is installed on the top cover 131 in a manner that the bottom of the emitting array 134 sinks into the groove 1310 of the top cover 131, the cover ring 1312 and the baffle 1313 are respectively located at the rear side and the front side of the emitting array 134 to protect the emitting array 134 and avoid the emitting array 134 from being collided as much as possible. The cover ring 1312 surrounds the top of the front plate 1331, and the vulcanization part 132 is formed inside the cover ring 1312 of the top cover 131. Preferably, the shape and size of the baffle 1313 of the top cover 131 are consistent with the shape and size of the portion of the transmitting array 134 that is not sunken into the groove 1310 of the top cover 131. In this way, the baffle 1313 of the top cover 131 can not only protect the transmitting array 134, but also prevent the sound wave signal from being emitted outward by the transmitting array 134.

[0052] Reference Figure 1 , Figure 5 , Figure 7 , Fig.10 , Fig.11 and Fig.13The top cover 131 further has two inclined surfaces 1314, which extend outward obliquely from opposite sides of the groove 1310 of the top cover 131, and the angle formed between the extension directions of the two inclined surfaces 1314 is an obtuse angle. That is, there is one inclined surface 1314 on opposite sides of the transmitting array 134, so that when the sonar moves in the water, the inclined surface 1314 of the top cover 131 can push the water flow to the two sides of the transmitting array 134, avoiding the generation of tiny bubbles on the opposite sides of the transmitting array 134, ensuring that the sound wave signal emitted by the transmitting array 134 only needs to pass through one medium (i.e., water) to radiate toward the direction of the detected area and the reflected sound wave from the detected area only needs to pass through one medium (i.e., water) to be received by the receiving array 133, thereby ensuring the accuracy of the detection result of the sonar on the detected area, and at the same time, the transmitting array 134 can have a larger field of view to avoid interference. Preferably, the two inclined surfaces 1314 of the top cover 131 are symmetrical to each other.

[0053] Reference Figure 5 and Figure 6 The top cover 131 has a wire through hole 1315, and the wire through hole 1315 extends from the bottom of the groove 1310 to the lower surface of the top cover 131, that is, the wire through hole 1315 of the top cover 131 passes through the top and bottom of the top cover 131, wherein the cable of the transmitting array 134 extends to the cabin cavity 111 of the cabin body 11 after passing through the wire through hole 1315 of the top cover 131, so that the cable of the transmitting array 134 can be connected to the circuit board assembly 14.

[0054] Reference Figure 5 and Figure 6, the top cover 131 has at least one top cover screw hole 1316, the transmitting array 134 has at least one array body threaded hole 1341, the array body threaded hole 1341 of the transmitting array 134 corresponds to the top cover screw hole 1316 of the top cover 131, the sonar body 10 includes at least one screw 15, the threaded end of the screw 15 extends to the array body threaded hole 1341 of the transmitting array 134 after passing through the top cover screw hole 1316 of the top cover 131, and the threaded end of the screw 15 is screwed to the transmitting array 134, so that the transmitting array 134 is installed on the top cover 131. It can be understood that after the threaded end of the screw 15 exits the array body threaded hole 1341 of the transmitting array 134, the transmitting array 134 can be detached. That is to say, in this specific example of the sonar of the present invention, the top cover 131, the vulcanization part 132 and the receiving array 133 are combined into a whole, and the transmitting array 134 is installed on the top cover 131, so that when the receiving array 133 is damaged, the transmitting array 134 can be reused. When the transmitting array 134 is damaged, the sonar can be repaired by replacing a new transmitting array 134, which can reduce the difficulty and cost of repairing the sonar and avoid the waste of accessories. Preferably, the sealing ring 40 is provided between the transmitting array 134 and the top cover 131 to increase the water tightness of the installation position of the transmitting array 134 and the top cover 131. In a specific example of the sonar of the present invention, the number of the top cover screw holes 1316 of the top cover 131 is two, and the two top cover screw holes 1316 are located on opposite sides of the wire through-hole 1315 of the top cover 131. Correspondingly, the number of the array body threaded holes 1341 of the transmitting array 134 is two, and the two array body threaded holes 1341 of the transmitting array 134 and the two top cover screw holes 1316 of the top cover 131 correspond to each other, and the threaded ends of the two screws 15 extend to the two array body threaded holes 1341 of the transmitting array 134 after respectively passing through the two top cover screw holes 1316 of the top cover 131, so that the transmitting array 134 can be reliably installed on the top cover 131.

[0055] It is understandable that in the process of vulcanizing the vulcanization portion 132 on the top of the top cover 131, the receiving array 133 may be slightly tilted, and the amount of tilt can be obtained by measuring after the sonar is powered on. In the process of installing the transmitting array 134, the tilt of the transmitting array 134 can be fine-tuned to make the receiving array 133 and the transmitting array 134 compatible, thereby ensuring the performance of the sonar.

[0056] Reference Figure 5 and Figure 6The top cover 131 has a positioning groove 13113, and the positioning groove 13113 is recessed from one side of the mounting groove 1310. The emitting array 134 has a positioning protrusion 1340, and the positioning boss 1340 is at the bottom of the emitting array 134. When a part of the emitting array 134 sinks to the mounting groove 1310 of the top cover 131, the positioning boss 1340 of the emitting array 134 extends into the positioning groove 13113 of the fixed cover 131, so as to avoid the installation direction of the emitting array 134 being reversed, thereby realizing the "fool-proof" assembly of the emitting array 134. Preferably, the size of the positioning groove 13113 of the top cover 13 is slightly larger than the size of the positioning boss 1340 of the transmitting array 134, so that during the installation of the transmitting array 134, the inclination of the transmitting array 134 can be fine-tuned to make the receiving array 133 and the transmitting array 134 compatible, thereby ensuring the performance of the sonar.

[0057] Reference Figure 4 The middle part of the front side of the cabin 11 is provided with a terminal groove 113 and a terminal mounting platform 114, the notch of the terminal groove 113 faces outward, the terminal channel 112 is provided on the terminal mounting platform 114, and the terminal channel 112 communicates the cabin cavity 111 and the terminal groove 113. The watertight terminal 12 is installed on the terminal mounting platform 114 of the cabin 11, and the outer end of the watertight terminal 12 is located in the terminal groove 113 of the cabin 11. By providing the terminal groove 113 on the front side of the cabin 11, the sonar can avoid the outer end of the watertight terminal 12 protruding from the front side of the cabin 11, so that when the sonar is transported, the space occupied by the sonar can be reduced, and by avoiding the outer end of the watertight terminal 12 from being collided, not only the reliability of the connection relationship between the watertight terminal 12 and the circuit board assembly 14 can be ensured, but also the watertightness of the installation position of the watertight terminal 12 and the cabin 11 can be ensured.

[0058] Preferably, continue to refer to the attached Figure 4, the terminal mounting platform 114 of the cabin 11 is extended obliquely, and there is an acute angle between it and the horizontal plane, so that there is an acute angle between the extension direction of the watertight terminal 12 and the height direction of the sonar. In this way, not only can the space of the cabin cavity 111 of the cabin 11 be saved, but also the space of the cabin cavity 111 of the cabin 11 can be made more regular, which is conducive to making full use of the cabin cavity 111 of the cabin 11. In addition, by setting the watertight terminal 12 obliquely, when connecting the watertight terminal 12 and the cable of the ship or submarine equipment, it is not only convenient to tighten the nut used to connect the watertight terminal 12 and the cable by hand, but also after the sonar is equipped to the application environment, it can avoid the problem that the connection position of the cable and the watertight terminal 12 is easily stressed and broken due to the need for the cable to extend horizontally.

[0059] It can be understood that the angle formed between the extension direction of the watertight terminal 12 and the height direction of the sonar should be neither too small nor too large. If the angle formed between the extension direction of the watertight terminal 12 and the height direction of the sonar is too small, the watertight terminal 12 tends to be vertically arranged, resulting in the above-mentioned beneficial effect of the inclined watertight terminal 12 being not obvious. If the angle formed between the inclined direction of the watertight terminal 12 and the height direction of the sonar is too large, the watertight terminal 12 tends to be horizontally arranged, which also results in the above-mentioned beneficial effect of the inclined watertight terminal 12 being not obvious. Therefore, in the sonar of the present invention, in order to ensure that the inclined watertight terminal 12 obviously has the above-mentioned beneficial effect, the angle formed between the extension direction of the watertight terminal 12 and the height direction of the sonar is preferably not less than 15°, and the maximum should not be greater than 30°, that is, the appropriate value range of the angle formed between the extension direction of the watertight terminal 12 and the height direction of the sonar is 15°-30°.

[0060] Reference Figure 7 , Figure 8 , Fig.15 and Fig.16At least one front-amplifier board chip 1332 is mounted on the bottom of the front-amplifier board 1331 of the receiving array 133, and the top cover 131 has at least one abutment platform 1317, which extends downward from the edge of the front-amplifier board through-hole 1311, and the abutment platform 1317 has an abutment slope 13170, and the front-amplifier board chip 1332 mounted on the bottom of the front-amplifier board 1331 and the abutment slope 13170 of the abutment platform 1317 are arranged adjacent to each other and are offset in the horizontal direction. The sonar body 10 further includes at least one clamping assembly 17, which includes at least one clamping plate 171 and an assembly arm 172, wherein the clamping plate 171 is arranged at the end of the assembly arm 172, the clamping plate 171 has a clamping plane 1711, and the assembly arm 172 has a driven inclined surface 1721, wherein the assembly arm 172 is installed on the top cover 131, the clamping plane 1711 of the clamping plate 171 is in contact with the front amplifier board chip 1332 at the bottom of the front amplifier board 1331, and the driven inclined surface 1721 of the assembly arm 172 is in contact with the abutting inclined surface 13170 of the abutting platform 1317, in this way, the heat generated by the front amplifier board chip 1332 at the bottom of the front amplifier board 1331 during operation can be conducted to the top cover 131 through the clamping assembly 17, and dissipated through the top cover 131. Since the peripheral wall of the top cover 131 is exposed and has a large area, the sonar has a good heat dissipation effect. Optionally, in other examples of the sonar of the present invention, the front amplifier board chip 1332 mounted on the bottom of the front amplifier board 1331 and the abutting slope 13170 of the abutting platform 1317 can also be arranged face to face.

[0061] In a specific example of the sonar of the present invention, the edge of the front amplifier board through hole 1311 of the top cover 131 has two downwardly extending abutment platforms 1317, and the bottom of the front amplifier board 1331 has two front amplifier board chips 1332. Correspondingly, the clamping assembly 17 includes two clamping plates 171 and an assembly arm 172, and the opposite ends of the assembly arm 172 are respectively provided with a clamping plate 171, and the clamping planes 1711 of each clamping plate 171 are respectively attached to each front amplifier board chip 1332 at the bottom of the front amplifier board 1331.

[0062] In a specific example of the sonar of the present invention, the top cover 131 has two front-stage plate through-holes 1311, the receiving array 133 has two front-stage plates 1331, and the top of each front-stage plate 1331 extends from the bottom of the top cover 131 to the top through each front-stage plate through-hole 1311 of the top cover 131, wherein the vulcanized portion 132 is vulcanized on the top of the top cover 131, and the vulcanized portion 132 wraps the top of each front-stage plate 1331, so that the top cover 131, the vulcanized portion 132 and the receiving array 133 are combined into a whole. It can be understood that in this embodiment of the sonar, the number of the clamping components 17 is two.

[0063] Reference Fig.15 and Fig.16 The top cover 131 has at least one first threaded hole 1318, and the assembly arm 172 has at least one first screw hole 1722. The first screw hole 1722 of the assembly arm 172 corresponds to the first threaded hole 1318 of the top cover 131, wherein the threaded end of the screw 15 extends to the first threaded hole 1318 of the top cover 131 after passing through the first screw hole 1722 of the assembly arm 172, so as to install the assembly arm 172 on the top cover 131. In a specific example of the sonar of the present invention, the number of the first threaded holes 1318 of the top cover 131 is two, and correspondingly, the number of the first screw holes 1722 of the assembly arm 172 is two, and the threaded ends of the two screws 15 extend to the two first threaded holes 1318 of the top cover 131 after passing through the two first screw holes 1722 of the assembly arm 172 respectively, thereby preventing the assembly arm 172 from tilting, so that the pressing planes 1711 of the two pressing plates 171 are respectively tightly fitted to the two front amplifier board chips 1332 at the bottom of the front amplifier board 1331.

[0064] The process of installing the clamping assembly 17 may be: first, allow the threaded end of the screw 15 to align with the first threaded hole 1318 of the top cover 131 after passing through the first screw hole 1722 of the assembly arm 172, at which time the driven inclined surface 1721 of the assembly arm 172 is in contact with the abutting inclined surface 13170 of the abutting platform 1317, and each of the clamping pieces 171 is adjacent to each of the front plate chips 1332 at the bottom of the front plate 1331; second, rotate the screw 15 to allow the threaded end of the screw 15 to be screwed onto the top cover 131 The first threaded hole 1318 of the top cover 131 is extended to the first threaded hole 1318 of the top cover 131 in a manner. As the threading depth of the screw rod 15 changes, the screw rod 15 pushes the clamping assembly 17 to move upward. In this process, the driven inclined surface 1721 of the assembly arm 172 and the abutting inclined surface 13170 of the abutting platform 1317 cooperate with each other to drive the clamping assembly 17 to move toward the front-stage chip 1332 near the bottom of the front-stage 1331, so that the clamping plane 1711 of each clamping sheet 171 is in close contact with each front-stage chip 1332. Preferably, thermal conductive silicone grease may be provided between the clamping plane 1711 of the clamping sheet 171 and the front-stage chip 1332.

[0065] The front amplifier chip 1332 at the bottom of the front amplifier board 1331 is a chip for receiving and processing sound wave signals, so that the circuit board assembly 14 of the present invention does not need to be provided with a receiving circuit board. In other words, in this specific example of the sonar of the present invention, the chip of the receiving circuit board in the traditional sonar is integrated into the front amplifier board 1331 to form the front amplifier chip 1332, so that the sonar of the present invention can omit the receiving circuit board, which is conducive to reducing the cost of the sonar and making the sonar miniaturized and lightweight. At the same time, on the one hand, since the chip for receiving and processing sound wave signals is integrated into the front amplifier board 1331 to form the front amplifier board chip 1332, the front amplifier board chip 1332 can be adjacent to the top cover 131, so that the heat generated by the front amplifier board chip 1332 during operation can be quickly conducted to the top cover 131 via the clamping assembly 17 and dissipated through the top cover 131. On the other hand, since the chip for receiving and processing sound wave signals is integrated into the front amplifier board 1331 to form the front amplifier board chip 1332, the heat source of the sonar is dispersed, which is beneficial to the heat dissipation of the sonar.

[0066] In addition, refer to the attached Figure 4 and Figure 7, the front amplifier board chips 1332 are arranged on the top of the front amplifier board 1331, and these front amplifier board chips 1332 are wrapped by the vulcanization part 132. The transceiver array assembly 13 further includes at least one array heat conductive sheet 135, the top of which is overlapped with the front amplifier board chips 1332 on the top of the front amplifier board 1331, and the bottom of which extends to the top cover 131. The heat generated by the front amplifier board chips 1332 on the top of the front amplifier board 1331 during operation is conducted to the top cover 131 through the array heat conductive sheet 135, and the heat is dissipated through the top cover 131. It can be understood that the vulcanization part 132 can wrap the top of the array heat conductive sheet 135, so that the array heat conductive sheet 135 is reliably overlapped with the front amplifier board chips 1332 on the top of the front amplifier board 1331. Optionally, the entire array heat conductive sheet 135 may be wrapped by the vulcanization portion 132 .

When the top cover 131 is installed on the cabin 11, the circuit board assembly 14 is accommodated in the cabin cavity 111 of the cabin 11 by the top cover 131. In this way, the connection operation between the main control board 142 and the transmitting board 143, and the connection operation between the main control board 142 and the front amplifier board 1331 can be performed outside the cabin cavity 111 of the cabin 11, so that the connection operation between the main control board 142 and the transmitting board 143, and the connection operation between the main control board 142 and the front amplifier board 1331 do not need to be performed in a small space, so as to facilitate the assembly of the sonar. In the sonar of the present invention, the circuit board assembly 14 does not include a receiving circuit board to reduce the number of circuit boards, which is beneficial to reducing the cost of the sonar and reducing the size of the sonar, so that the sonar can be miniaturized and lightweight.

[0069] In addition, the module frame 141 can be made of a material with good thermal conductivity, such as copper, aluminum, copper alloy, aluminum alloy, etc. Since the main control board 142 and the launch board 143 are installed on the module frame 141 and the module frame 141 is installed on the top cover 131, the heat generated by the main control board 142 and the launch board 143 during operation can be quickly transferred to the top cover 131 through the module frame 141, and dissipated through the top cover 131. Preferably, the bottom of the module frame 141 is in surface contact with the cabin 11, so that the heat generated by the main control board 142 and the launch board 143 during operation can also be quickly transferred to the cabin 11 through the module frame 141, and dissipated through the cabin 11.

In this specific example of the sonar of the present invention, a third screw hole 1421 is respectively provided at the four corners of the frame vertical plate 1412, and a third screw hole 1421 is respectively provided at the four corners of the main control board 142. Correspondingly, the number of the isolation locking parts 1413 is four, so that the four isolation locking parts 1413 can reliably install the main control board 142 on the module frame 141.

[0073] Preferably, the frame body vertical plate 1412 has a vertical plate boss 14123, and the main control board 142 has a main control board chip 1422. The main control board chip 1422 of the main control board 142 is attached to the vertical plate boss 14123 of the frame body vertical plate 1412, so that the heat generated by the main control board chip 1422 of the main control board 142 during operation can be directly conducted to the frame body vertical plate 1412.

In this specific example of the sonar of the present invention, a fourth screw hole 1431 is respectively provided at each corner of the launch plate 143, so that the four screws 15 reliably install the launch plate 143 on the module frame 141.

[0075] Continue to refer to the attached Fig.19 and Fig. 20 The main control board 142 has a main control board connector 1423, and the transmitting board 143 has a transmitting board connector 1432. The main control board connector 1423 of the main control board 142 and the transmitting board connector 1432 of the transmitting board 143 cooperate with each other to conduct the main control board 142 and the transmitting board 143. In this way, no flying wire is required between the main control board 142 and the transmitting board 143, thereby not only avoiding the problem of desoldering of the solder joints of the flying wires during the assembly of the sonar, but also avoiding the problem of degradation of the actual performance of the sonar due to poor consistency of the solder joints.

[0076] Reference Fig.17 and Fig.19The launch board 143 has a launch board chip 1433, and the module frame 141 includes a frame heat conductive sheet 1414, which is installed on one side of the frame bottom plate 1411, and the frame heat conductive sheet 1414 is stacked on the launch board chip 1433 of the launch board 143, so that the heat generated by the launch board chip 1433 of the launch board 143 during operation is conducted to the cabin 11 through the frame heat conductive sheet 1414 and the frame bottom plate 1411, and dissipated through the cabin 11. Preferably, thermal grease is provided between the launch board chip 1433 of the launch board 143 and the frame heat conductive sheet 1414.

[0077] Specifically, the frame bottom plate 1411 has at least one seventh screw hole 14112, and the frame heat conductive plate 1414 has at least one seventh threaded hole 14141.

In this specific example of the sonar of the present invention, the frame bottom plate 1411 has two seventh screw holes 14112, and the frame heat conductive plate 1414 has two seventh threaded holes 14141, so that the two screws 15 are used to reliably mount the frame heat conductive plate 1414 on the frame bottom plate 1411.

[0078] Reference Figures 9 to 12 , Figures 17 to 20 The frame upright plate 1412 of the module frame 141 is installed on the top cover 131 to install the module frame 141 on the top cover 131.

[0079] Specifically, the module frame 141 has an extension arm 14124 on opposite sides of the top of the frame upright plate 1412, and the frame upright plate 1412 further has two fifth screw holes 14125, and each of the extension arms 14124 is respectively provided with a fifth screw hole 14125, and the top cover 131 has a fifth threaded hole 1319 on opposite sides, and each of the fifth threaded holes 1319 of the top cover 131 corresponds to the fifth screw hole 14125 of the frame upright plate 1412, respectively. The threaded ends of the two screws 15 extend to the two fifth threaded holes 1319 of the top cover 131 after respectively passing through the two fifth screw holes 14125 of the frame upright plate 1412, and the threaded ends of the screws 15 are screwed on the top cover 131, and the module frame 141 is mounted on the top cover 131 by the screws 15.

[0080] Reference Fig.13 and Fig.14 The front amplifier board 1331 has a front amplifier board cable head 13311, the main control board 142 has a main control board cable head 1424, the sonar body 10 includes a soft flat cable 18, the first cable head 181 of the soft flat cable 18 is installed on the front amplifier board cable head 13311 of the front amplifier board 1331, the second cable head 182 of the soft flat cable 18 is installed on the main control board cable head 1424 of the main control board 142, so that the front amplifier board 1331 and the main control board 142 are connected by the soft flat cable 18.

[0081] The extension direction of the front amplifier board 1331 is consistent with the extension direction of the main control board 142, and the main control board 142 is located below the front amplifier board 1331. Since the sonar needs to be miniaturized, the distance between the top of the main control board 142 and the bottom of the front amplifier board 1331 is relatively small. Limited by the connection relationship between the main control board 142 and the soft flat cable 18 and the front amplifier board 1331 and the soft flat cable 18, if the main control board cable head 1424 of the main control board 142 is located directly below the front board cable head 13311 of the front amplifier board 1331, then in the process of installing the top of the frame vertical plate 1412 on the top cover 131, the first cable head 181 and the second cable head 182 of the soft flat cable 18 are subjected to lateral force, causing the first cable head 181 and the second cable head 182 of the soft flat cable 18 to loosen or even fall off. In this specific example of the sonar of the present invention, the front amplifier board cable head 13311 of the front amplifier board 1331 and the main control board cable head 1424 of the main control board 142 are misaligned in the horizontal direction, so that the front amplifier board cable head 13311 and the main control board cable head 1424 have a larger distance, thereby avoiding lateral force on the first cable head 181 and the second cable head 182 of the soft cable 18 during the installation of the top of the frame vertical plate 1412 on the top cover 131, thereby ensuring the reliability of the connection relationship between the first cable head 181 of the soft cable 18 and the front amplifier board cable head 13311 of the front amplifier board 1331 and the reliability of the connection relationship between the second cable head 182 and the main control board cable head 1424 of the main control board 142.

[0084] By installing the power board 144 on the top cover 131, on the one hand, the sonar can disperse the heat source, and on the other hand, the heat generated by the power board 144 during operation can be directly conducted to the top cover 131 and dissipated through the top cover 131, thereby improving the heat dissipation efficiency of the sonar.

[0085] Preferably, the power board 144 has an avoidance channel 1442 , and the inner diameter of the avoidance channel 1442 is larger than the size of the nut 30 , so that the power board 144 can avoid the nut 30 .

[0086] Reference Figure 4The sonar body 10 includes a filter board 16, which is installed on the cabin 11 and connected to the watertight terminal 12. The filter board 16 and the main control board 142 can be connected through the soft flat cable 18, wherein the filter board 16 is used to provide a filtering function for removing noise interference and / or performing frequency selection. Preferably, the filter board 16 is adjacent to the inner end of the watertight terminal 12, so that the inner end of the watertight terminal 12 can be directly connected to the filter board 16, so that the distance between the wire of the watertight terminal 12 and the filter board 16 is short, so that even if the wire of the watertight terminal 16 is not provided with a shielding layer, the sonar can also have a good electromagnetic shielding function.

[0088] Furthermore, the top cover 131 has a slot 13111, which is located in the middle section of the assembly slot 101. After the pressure sensor 20 is installed in the assembly slot 101 of the sonar body 10, the top of the pressure sensor 20 is flush with the lower edge of the slot 13111 of the top cover 131, wherein the sonar further includes a retaining spring 50, the outer edge of the retaining spring 50 is retained in the slot 13111 of the top cover 131, and the inner edge of the retaining spring 50 is pressed on the top of the pressure sensor 20, so that the pressure sensor 20 is installed in the assembly slot 101 of the sonar body 10.
