Technical Field
[0001] The present invention relates to a sonar, in particular to a sonar with a pressure sensor. Background Art
[0002] Sonar technology plays a crucial role in many areas today, including ocean exploration, underwater monitoring, and navigation. Existing sonar primarily uses the propagation characteristics of sound waves in water to detect targets, such as submarines, schools of fish, and seafloor topography. However, as these applications continue to expand and deepen, higher requirements are placed on the accuracy and comprehensiveness of the information obtained by sonar systems. Depth information is an essential parameter in the marine environment. Whether conducting marine scientific research to understand water temperature, salinity, current velocity, and the distribution of marine biomes at different depths, or ensuring navigational safety by determining the precise depth beneath a vessel to avoid dangers such as grounding, depth data is crucial. However, existing sonar systems often lack direct and accurate depth measurement capabilities and must rely on indirect methods or the use of separate, independent depth measurement equipment to obtain depth information. This not only increases equipment complexity, cost, and installation space, but also introduces errors and delays in data integration and synchronization. Summary of the Invention

[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 set forth in the following description or illustrated in the following figures. The present invention is capable of other embodiments and can be practiced or carried out in various ways. In addition, it should be understood that the words and terms used herein are for descriptive purposes and should not be considered restrictive. The use of "including" or "having" and their variations herein is intended to cover the items and their equivalents set forth below and additional items. Unless otherwise specified or limited, the terms "mounted", "connected", "supported" and "coupled" and their variations are used broadly and cover direct mounting and indirect mounting, connection, support and coupling. In addition, "connected" and "coupled" are not limited to physical or mechanical connections or couplings.
[0041] Furthermore, on the first hand, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships 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 operated in a specific orientation, and therefore the above terms cannot be understood as limitations on the present invention; on the second hand, 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] Reference is made to the accompanying drawings of the present invention. Figures 1 to 20 In the following description, a sonar with a pressure sensor according to a preferred embodiment of the present invention will be disclosed and explained, 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 performs underwater detection 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 a mounting slot 101, and the pressure sensor 20 is mounted in the mounting slot 101 of the sonar body 10. This prevents the pressure sensor 20 from protruding from the surface of the sonar body 10, thereby preventing it from affecting the acoustic performance of the sonar when the sonar moves through water. For example, the pressure sensor 20 does not cause bubbles to form in the sonar's surrounding environment. As a result, the acoustic wave signals emitted by the sonar body 10 only need to pass through one medium (i.e., water) to radiate toward the detected area, and the reflected acoustic waves from the detected area only need to pass through one medium (i.e., water) to be received by the sonar body 10, thereby ensuring the accuracy of the sonar's detection results of the detected area.
[0044] Reference Attachment 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 opening 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 mounted on the transceiver array assembly 13, and the circuit board assembly 14 is housed in the chamber 111 of the cabin 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 can be mounted on 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 11, so that the pressure sensor 20 can be mounted on the cabin 11.
[0045] Reference Attachment Figure 4 、 Figure 5 、 Figure 7 、 Figures 13 to 16The transceiver array assembly 13 further includes a top cover 131, a vulcanized portion 132, a receiving array 133 and a transmitting array 134, wherein the vulcanized portion 132 is vulcanized on the top cover 131, and the vulcanized portion 132 is combined with the receiving array 133 during the vulcanization process, so that the top cover 131, the vulcanized portion 132 and the receiving array 133 are combined into a whole, 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 Attachment Figure 4 and Figure 5 The assembly slot 101 of the sonar body 10 is formed in the top cover 131. Therefore, 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. 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 being exposed, thereby protecting the pressure sensor 20. On the other hand, the arrangement of the pressure sensor 20 does not affect the overall appearance of the sonar, so that the pressure sensor 20 does not affect the acoustic performance of the sonar.
[0047] Preferably, the assembly slot 101 of the sonar body 10 has a receiving slot 1011 and an assembly through hole 1012 extending from the receiving slot 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 slot 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 accommodating groove 1011 of the sonar body 10, and the sonar further includes a nut 30, which is screwed onto 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 watertightness 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. This helps reduce the height of the sonar, thereby facilitating the miniaturization of the sonar. After the transmitting array 134 is installed on the top cover 131 with the bottom of the transmitting array 134 sinking 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 pass through the water flow channel 102 of the sonar body 10 to reach the pressure sensor 20, so that the pressure sensor 20 measures the current depth of the sonar by measuring the water pressure.
[0050] Reference Attachment 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, which are respectively located at the rear and front sides of the groove 1310 of the top cover 131. After the emitting array 134 is installed in the top cover 131 with its bottom portion sunk into the groove 1310 of the top cover 131, the cover ring 1312 and baffle 1313 are respectively located at the rear and front sides of the emitting array 134 to protect the emitting array 134 and minimize collisions. The cover ring 1312 surrounds the top of the front plate 1331, and the vulcanized portion 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 emitting 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 emitting array 134, but also prevent the emitting array 134 from emitting sound wave signals outward.
[0052] Reference Attachment Figure 1 、 Figure 5 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 13The top cover 131 further has two inclined surfaces 1314 extending outwardly from opposite sides of the groove 1310 of the top cover 131 , with the angle between the two inclined surfaces 1314 being obtuse. In other words, with one inclined surface 1314 on each opposite side of the transmitting array 134, when the sonar moves through the water, the inclined surfaces 1314 of the top cover 131 can push water away from the transmitting array 134, preventing the formation of tiny bubbles on opposite sides of the transmitting array 134. This ensures that the acoustic wave signals emitted by the transmitting array 134 only need to pass through one medium (i.e., water) to radiate toward the detected area, and that the reflected acoustic waves from the detected area only need to pass through one medium (i.e., water) to be received by the receiving array 133, thereby ensuring the accuracy of the sonar's detection results of the detected area. Furthermore, the transmitting array 134 can have a wider field of view and avoid interference. Preferably, the two inclined surfaces 1314 of the top cover 131 are symmetrical to each other.
[0053] Reference Attachment 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 Attachment Figure 5 and Figure 6The top cover 131 has at least one top cover screw hole 1316, and 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. The threaded end of the screw 15 is screwed onto 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, in this specific example of the sonar of the present invention, the top cover 131, the vulcanized portion 132, and the receiving array 133 are integrated into a single unit, and the transmitting array 134 is mounted on the top cover 131. Thus, if the receiving array 133 is damaged, the transmitting array 134 can be reused. If the transmitting array 134 is damaged, the sonar can be repaired by replacing it with a new one. This reduces the difficulty and cost of repairing the sonar and avoids the waste of spare parts. Preferably, a sealing ring 40 is provided between the transmitting array 134 and the top cover 131 to enhance the watertightness of the mounting location 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 correspond to the two top cover screw holes 1316 of the top cover 131 respectively. 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. 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 Attachment 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, thereby preventing the installation direction of the emitting array 134 from 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 Attachment Figure 4 The front center of the housing 11 has a terminal slot 113 and a terminal mounting platform 114. The notch of the terminal slot 113 faces outward, and the terminal channel 112 is located on the terminal mounting platform 114, connecting the housing 111 and the terminal slot 113. The watertight terminal 12 is mounted on the terminal mounting platform 114 of the housing 11, with the outer end of the watertight terminal 12 located in the terminal slot 113 of the housing 11. Providing the terminal slot 113 on the front side of the housing 11 prevents the outer end of the watertight terminal 12 from protruding from the front side of the housing 11, thereby reducing the space occupied by the sonar during transportation. This prevents the outer end of the watertight terminal 12 from being impacted, ensuring not only the reliable connection between the watertight terminal 12 and the circuit board assembly 14, but also the watertightness of the installation between the watertight terminal 12 and the housing 11.
[0058] Preferably, continue to refer to the attached Figure 4The terminal mounting platform 114 of the cabin 11 is inclined and extends at an acute angle to the horizontal plane. Thus, the extension direction of the watertight terminal 12 forms an acute angle with the height direction of the sonar. In this way, not only can the space of the chamber 111 of the cabin 11 be saved, but the space of the chamber 111 of the cabin 11 can also be made more regular, which is conducive to fully utilizing the chamber 111 of the cabin 11. In addition, by arranging the watertight terminal 12 at an angle, when connecting the watertight terminal 12 to the cable of a ship or underwater vehicle, it is not only convenient to manually tighten the nut used to connect the watertight terminal 12 and the cable, but also, after the sonar is installed in the application environment, the problem of the connection between the cable and the watertight terminal 12 being easily stressed and broken due to the need for the cable to extend horizontally can be avoided.
[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 arranged vertically, resulting in the above-mentioned beneficial effect of the inclined watertight terminal 12 being less 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 arranged horizontally, which also results in the above-mentioned beneficial effect of the inclined watertight terminal 12 being less obvious. Therefore, in the sonar of the present invention, in order to ensure that the inclined watertight terminal 12 clearly 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 not 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 Attachment Figure 7 、 Figure 8 、 Figure 15 and Figure 16At least one front amplifier board chip 1332 is mounted on the bottom of the front amplifier board 1331 of the receiving array 133. The top cover 131 has at least one abutment platform 1317. The abutment platform 1317 extends downward from the edge of the front amplifier board through-hole 1311, and the abutment platform 1317 has an abutment slope 13170. 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 staggered 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. The clamping plate 171 is arranged at the end of the assembly arm 172, and 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, and 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. Because 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 abutment slope 13170 of the abutment 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 plate through-hole 1311 of the top cover 131 has two downwardly extending abutment platforms 1317, and the bottom of the front plate 1331 has two front plate chips 1332. Accordingly, 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 plane 1711 of each clamping plate 171 is respectively attached to each front plate chip 1332 at the bottom of the front plate 1331.
[0062] In a specific example of the sonar of the present invention, the top cover 131 has two front-amplifying plate through-holes 1311, and the receiving array 133 has two front-amplifying plates 1331. The top of each front-amplifying plate 1331 extends from the bottom to the top of the top cover 131 through the respective front-amplifying plate through-holes 1311 of the top cover 131. The vulcanized portion 132 is vulcanized on the top of the top cover 131 and wraps around the top of each front-amplifying plate 1331. Thus, the top cover 131, the vulcanized portion 132, and the receiving array 133 are integrated into a single unit. It will be appreciated that in this embodiment of the sonar, the number of the clamping assemblies 17 is two.
[0063] Reference Attachment Figure 15 and Figure 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 accordingly, 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 respectively passing through the two first screw holes 1722 of the assembly arm 172, 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 can be as follows: 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 this 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; secondly, rotate the screw 15 to allow the threaded end of the screw 15 to be screwed onto the top cover 131 The screw 15 extends to the first threaded hole 1318 of the top cover 131 in a manner such that, as the threading depth of the screw 15 changes, the screw 15 pushes the clamping assembly 17 upward. During 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 toward the front amplifier board chip 1332 near the bottom of the front amplifier board 1331, so that the clamping surface 1711 of each clamping piece 171 is in close contact with each front amplifier board chip 1332. Preferably, thermal grease may be provided between the clamping surface 1711 of the clamping piece 171 and the front amplifier board chip 1332.
[0065] The front-amplifier chip 1332 at the bottom of the front-amplifier board 1331 functions as a chip for receiving and processing acoustic signals. Thus, the circuit board assembly 14 of the present invention eliminates the need for a receiving circuit board. In other words, in this specific example of the sonar of the present invention, the receiving circuit board chip of a conventional sonar is integrated into the front-amplifier board 1331 to form the front-amplifier chip 1332. This eliminates the need for a receiving circuit board, thereby reducing the cost of the sonar and making it more compact 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 through 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 7The front amplifier board chips 1332 are disposed on the top of the front amplifier board 1331, and these front amplifier board chips 1332 are wrapped by the vulcanization portion 132. The transceiver array assembly 13 further includes at least one array heat conducting plate 135. The top of the array heat conducting plate 135 is stacked on the front amplifier board chips 1332 on the top of the front amplifier board 1331, and the bottom of the array heat conducting plate 135 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 conducting plate 135, and dissipated through the top cover 131. It is understood that the vulcanization portion 132 can wrap the top of the array heat conducting plate 135, so that the array heat conducting plate 135 is securely stacked on the front amplifier board chips 1332 on the top of the front amplifier board 1331. Optionally, the entire array heat conducting sheet 135 may be wrapped by the vulcanization portion 132 .
[0067] Reference Attachment Figure 4 、 Figures 9 to 14 、 Figures 17 to 20 The circuit board assembly 14 includes a module frame 141, a main control board 142, and a launch board 143. The main control board 142 and the launch board 143 are installed on the module frame 141 at intervals, and the launch board 143 is connected to the main control board 142. The module frame 141 is installed on the top cover 131, and the main control board 142 and the front plate 1331 are connected. When the top cover 131 is installed on the cabin 11, the top cover 131 accommodates the circuit board assembly 14 in the cabin cavity 111 of the cabin 11.
[0068] That is to say, in this specific example of the sonar of the present invention, the main control board 142 and the transmitting board 143 are not directly installed on the cabin 11, but the main control board 142 and the transmitting board 143 are first installed on the module rack 141, and then the module rack 141 is installed on the top cover 131. 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 carried out 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 carried out 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 and 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 transmitting board 143 are mounted on the module frame 141 and the module frame 141 is mounted on the top cover 131, the heat generated by the main control board 142 and the transmitting 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. In this way, the heat generated by the main control board 142 and the transmitting board 143 during operation can also be quickly transferred to the cabin 11 through the module frame 141 and dissipated through the cabin 11.
[0070] Continue to refer to the attached Figures 17 to 20 The module frame 141 includes a frame bottom plate 1411 , a frame vertical plate 1412 and at least one isolation locking portion 1413 .
[0071] The bottom of the frame upright plate 1412 is mounted on one side of the frame bottom plate 1411, so that the module frame 141 is in an "L" shape as a whole. Specifically, the frame bottom plate 1411 has at least one second screw hole 14111, and the frame upright plate 1412 has at least one second threaded hole 14121. The second threaded hole 14121 of the frame upright plate 1412 corresponds to the second screw hole 14111 of the frame bottom plate 1411, wherein the threaded end of the screw 15 extends to the second threaded hole 14121 of the frame upright plate 1412 after passing through the second screw hole 14111 of the frame bottom plate 1411, and the frame bottom plate 1411 and the frame upright plate 1412 are locked by the screw 15, so that the bottom of the frame upright plate 1412 is mounted on one side of the frame bottom plate 1411. In this specific example of the sonar of the present invention, the frame bottom plate 1411 has a plurality of second screw holes 14111 spaced apart from each other, and the frame vertical plate 1412 has a plurality of second threaded holes 14121 spaced apart from each other, and the threaded ends of the plurality of screws 15 extend to the respective second threaded holes 14121 of the frame vertical plate 1412 after respectively passing through the respective second screw holes 14111 of the frame bottom plate 1411, so that the plurality of screws 15 are used to install the bottom of the frame vertical plate 1412 on one side of the frame bottom plate 1411.
[0072] The frame vertical plate 1412 has at least one third threaded hole 14122, the main control plate 142 has at least one third screw hole 1421, the isolation locking portion 1413 includes an isolation section 14131 and a screw section 14132 extending from the isolation section 14131, the outer diameter of the isolation section 14131 is larger than the inner diameter of the third screw hole 1421 of the main control plate 142, wherein the main control plate 142 is arranged on one side of the frame vertical plate 1412, The third screw hole 1421 of the main control board 142 corresponds to the third threaded hole 14122 of the frame vertical plate 1412, and the screwing section 14132 of the isolation locking part 1413 extends to the third threaded hole 14122 of the frame vertical plate 1412 after passing through the third screw hole 1421 of the main control board 142, and the screwing section 14132 is screwed to the frame vertical plate 1412, so that the main control board 142 is installed on the module frame 141. 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. Accordingly, the number of the isolation locking parts 1413 is four, so that the four isolation locking parts 1413 reliably install the main control board 142 on the module frame 141.
[0073] Preferably, the frame upright plate 1412 has a upright 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 upright plate boss 14123 of the frame upright plate 1412. In this way, the heat generated by the main control board chip 1422 of the main control board 142 during operation can be directly transferred to the frame upright plate 1412. Preferably, thermal grease is provided between the upright plate boss 14123 of the frame upright plate 1412 and the main control board chip 1422 of the main control board 142.
[0074] The isolation locking portion 1413 has a fourth threaded hole 14133, which is provided in the isolation section 14131. The launching plate 143 has at least one fourth screw hole 1431. The inner diameter of the fourth screw hole 1431 of the launching plate 143 is smaller than the outer diameter of the isolation section 14131 of the isolation locking portion 1413. The launching plate 143 is provided on one side of the main control board 131. The fourth screw hole 1431 of the launching plate 143 and the outer diameter of the fourth screw hole 1431 of the launching plate 143 are smaller than the outer diameter of the isolation section 14131 of the isolation locking portion 1413. The threaded end of the screw 15 passes through the fourth screw hole 1431 of the launch plate 143 and extends to the fourth threaded hole 14133 of the isolation locking portion 1413. The threaded end of the screw 15 is screwed onto the isolation locking portion 1413. In this manner, the launch plate 143 is mounted to the module frame 141, with the launch plate 143 and the main control board 142 spaced apart. In this specific example of the sonar of the present invention, a fourth screw hole 1431 is provided at each corner of the launch plate 143. Thus, the four screws 15 securely secure the launch plate 143 to the module frame 141.
[0075] Continue to refer to the attached Figure 19 and Figure 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 wires are required between the main control board 142 and the transmitting board 143, which not only avoids the problem of desoldering of the solder joints of the flying wires during the assembly of the sonar, but also avoids the problem of degradation of the actual performance of the sonar due to poor consistency of the solder joints.
[0076] Reference Attachment Figure 17 and Figure 19The launch plate 143 has a launch plate chip 1433, and the module frame 141 includes a frame heat conducting sheet 1414. The frame heat conducting sheet 1414 is mounted on one side of the frame base plate 1411 and is stacked on the launch plate chip 1433 of the launch plate 143. In this way, the heat generated by the launch plate chip 1433 of the launch plate 143 during operation is transferred to the cabin 11 through the frame heat conducting sheet 1414 and the frame base plate 1411, and dissipated by the cabin 11. Preferably, thermal grease is provided between the launch plate chip 1433 of the launch plate 143 and the frame heat conducting sheet 1414.
[0077] Specifically, the frame base plate 1411 has at least one seventh screw hole 14112, and the frame heat conducting plate 1414 has at least one seventh threaded hole 14141. The seventh threaded hole 14141 of the frame heat conducting plate 1414 corresponds to the seventh screw hole 14112 of the frame base plate 1411, wherein the threaded end of the screw 15 extends to the seventh threaded hole 14141 of the frame heat conducting plate 1414 after passing through the seventh screw hole 14112 of the frame base plate 1411, and the frame heat conducting plate 1414 is installed on one side of the frame base plate 1411 by the screw 15. In this specific example of the sonar of the present invention, the frame base plate 1411 has two seventh screw holes 14112, and the frame heat conducting plate 1414 has two seventh threaded holes 14141, so that the two screws 15 are used to reliably mount the frame heat conducting plate 1414 on the frame base plate 1411.
[0078] Reference Attachment 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 rack 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. Each of the extension arms 14124 is provided with a fifth screw hole 14125, and the top cover 131 has a fifth threaded hole 1319 on opposite sides. 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, and the threaded ends of the two screws 15 extend to the two fifth threaded holes 1319 of the top cover 131 after passing through the two fifth screw holes 14125 of the frame upright plate 1412, and the threaded ends of the screws 15 are screwed to the top cover 131, and the module rack 141 is mounted on the top cover 131 by the screw 15.
[0080] Reference Attachment Figure 13 and Figure 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, and the sonar body 10 includes a soft cable 18, the first cable head 181 of the soft cable 18 is installed on the front amplifier board cable head 13311 of the front amplifier board 1331, and the second cable head 182 of the soft 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 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. Due to 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 amplifier 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 process of installing 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.
[0082] In the attached Figures 1 to 20 In this specific example of the sonar of the present invention, a main control board cable connector 1424 is provided on opposite sides of the main control board 142. One flexible flat cable 18 connects one front-end amplifier board 1331 and the main control board 142 via one main control board cable connector 1424 of the main control board 142, and another flexible flat cable 18 connects another front-end amplifier board 1331 and the main control board 142 via another main control board cable connector 1424 of the main control board 142. Preferably, the transmitting board 143 has an avoidance notch 1434 for avoiding one main control board cable connector 1424 of the main control board 142.
[0083] The circuit board assembly 14 further includes a power board 144, which is mounted on the top cover 131. The transmitting array 134 and the pressure sensor 20 are respectively connected to the power board 144, and the power board 144 is connected to the transmitting board 143. In a specific example of the sonar of the present invention, the power board 144 is connected to the transmitting board 143 through the flexible cable 18. In order to install the power board 144 on the top cover 131, in the sonar of the present invention, refer to the attached Figure 14 The power board 144 has at least one sixth screw hole 1441, and the top cover 131 has at least one sixth threaded hole 13110. The sixth screw hole 1441 of the power board 144 corresponds to the sixth threaded hole 13110 of the top cover 131. The threaded end of the screw 15 extends to the sixth threaded hole 13110 of the top cover 131 after passing through the sixth screw hole 1441 of the power board 144, and the threaded end of the screw 15 is screwed to the top cover 131, and the power board 144 is installed on the top cover 131 by the screw 15. In a specific example of the sonar of the present invention, the number of the sixth screw holes 1441 of the power board 144 is more than two, and the number of the sixth threaded holes 13110 of the top cover 131 is more than two. The threaded ends of the respective screws 15 extend to the respective sixth threaded holes 13110 of the top cover 131 after respectively passing through the respective sixth screw holes 1441 of the power board 144, so that the respective screws 15 reliably mount the power board 144 on the top cover 131.
[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 Attachment Figure 4The sonar body 10 includes a filter board 16, which is mounted on the cabin 11 and connected to the watertight terminal 12. The filter board 16 and the main control board 142 can be connected via the flexible flat cable 18. The filter board 16 is used to provide filtering 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. This shortens the distance between the wires of the watertight terminal 12 and the filter board 16. Therefore, even without a shielding layer, the sonar can still have a good electromagnetic shielding function.
[0087] Figures 21 to 24 A modified example of the sonar is shown, with the attached Figures 1 to 20 The sonar shown is different in that Figures 21 to 24 In this particular example of the sonar shown, the pressure sensor 20 is located to the side of the transmit array 134 , ie, the pressure sensor 20 and the transmit array 134 are side by side.
[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. 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 against the top of the pressure sensor 20. In this way, the pressure sensor 20 is installed in the assembly slot 101 of the sonar body 10.
[0089] Preferably, the sonar includes a plug 60 having at least one plug through-hole 61, wherein the plug 60 is installed in the assembly groove 101 of the sonar body 10 to hide the pressure sensor 20, wherein water can reach the pressure sensor 20 through the plug through-hole 61 of the plug 60, and the current water pressure is measured by the pressure sensor 20.
[0090] In order to reliably install the plug 60 in the assembly groove 101 of the sonar body 10, refer to the attached Figure 22 and Figure 23The peripheral wall of the plug 60 has a plug groove 62, and the top cover 131 has at least one screw hole 13112, and the screw hole 13112 of the top cover 131 corresponds to the plug groove 62 of the plug 60, wherein the sonar includes at least one screw 70, and the screw 70 is screwed into the screw hole 13112 of the top cover 131, and one end of the screw 70 extends to the plug groove 62 of the plug 60.
