Description

Technical Field

[0001] The invention relates to the technical field of underwater detection, and in particular to a sonar with a bracket and a manufacturing method thereof. Background Art

[0002] Sonar technology is a core technology for underwater detection. Sonar is the core hardware that supports sonar technology. When working, the transmitting transducer of the transmitting unit of the sonar transmits a sonar signal with a specific frequency, power and waveform, and the receiving transducer of the receiving unit receives the reflected sound wave and processes it to achieve the detection of underwater targets. In the sonar of the prior art, the receiving transducer and the main control board are integrated together, which leads to the design and processing of the receiving transducer must rely on the main control board. After the receiving transducer is designed and processed based on the main control board, if the circuit of the main control board is adjusted, for example, if the main control board needs to change the hole position or add electronic components such as resistors, it will inevitably lead to the mismatch of the receiving transducer and cause the array to be scrapped. Since the price of the sonar receiving transducer is high, the mismatch of the receiving transducer caused by the circuit adjustment of the main control board and the scrapping of the array is extremely wasteful for the development and manufacture of the sonar. Summary of the invention

[0003] One object of the present invention is to provide a sonar with a bracket and a manufacturing method thereof, wherein the sonar allows a main control board and a receiving transducer to be separated, so that the design and processing of the receiving transducer are independent of the adjustment of the main control board. This is not only conducive to the flexible design of the main control board and the receiving transducer, but also during the manufacturing process, even if the main control board is adjusted, it will not affect the receiving transducer, or even if the receiving transducer is adjusted, it will not affect the main control board, thereby avoiding waste caused by the incompatibility between the adjusted main control board and the receiving transducer.

The radius of the circles where the two arc surfaces are located is consistent with the radius of the inner wall of the receiving chamber, so that the end faces at the opposite ends of the receiving component are in surface contact with the inner wall of the receiving chamber.

[0013] As an optional example of the present invention, the sonar includes a tightening unit, which pushes the receiving component to move laterally at the side of the receiving component so that the end surface of the receiving component is pressed against the inner wall of the receiving cabin.

[0014] As an optional example of the present invention, the two tightening units push the receiving component to move laterally at the sides of the receiving component and adjacent to the ends thereof, so that the end surface of the receiving component is pressed against the inner wall of the receiving chamber.

[0072] With reference to the accompanying drawings of the present invention Figures 1 to 28 A sonar with a bracket (hereinafter referred to as "sonar") according to a preferred embodiment of the present invention will be disclosed and explained in the following description. The sonar includes a transmitting unit 10 and a receiving unit 20. The transmitting unit 10 and the receiving unit 20 are installed with each other, wherein the transmitting unit 10 is used to transmit sound waves, and the receiving unit 20 is used to receive reflected sound waves and process them.

[0073] Specifically, the receiving unit 20 includes a receiving cabin 21, a receiving transducer 22, a bracket 23, a main control board 24 and a receiving assembly 25, wherein the receiving cabin 21 has a receiving cavity 211 and a hatch 212 formed at one end of the receiving cabin 21, wherein the receiving transducer 22 is arranged at the side of the receiving cabin 21, wherein the main control board 24 is installed on the bracket 23, wherein the bracket 23 is received in the receiving cavity 211 of the receiving cabin 21 through the hatch 212 of the receiving cabin 21, and the bracket 23 is directly locked to the receiving cabin 21, wherein the receiving assembly 25 is received in the receiving cavity 211 of the receiving cabin 21 through the hatch 212 of the receiving cabin 21, and the receiving assembly 25 is directly locked to the bracket 23. The transmitting unit 10 is installed in the receiving cabin 21 of the receiving unit 20, and the transmitting unit 10 closes the hatch 212 of the receiving cabin 21.

[0074] Preferably, refer to the attached Figures 2 to 4 The launching unit 10 is locked in the receiving cabin 21 by a set of screws 100 to install the launching unit 10 in the receiving cabin 21 , and the hatch 212 of the receiving cabin 21 is closed by the launching unit 10 . Specifically, the bottom of the launching unit 10 has an extension column 11, a peripheral edge 12 and a plurality of screw holes 13 formed on the peripheral edge 12, and the receiving cabin 21 has a plurality of threaded holes 214. After the extension column 11 of the launching unit 10 is inserted into the accommodating cavity 211 through the hatch 212 of the receiving cabin 21, the peripheral edge 12 of the launching unit 10 rests on the edge of the hatch 212 of the receiving cabin 21, and the positions of the respective screw holes 13 of the launching unit 10 correspond to the positions of the respective threaded holes 214 of the receiving cabin 21, wherein one end of each of the screws 100 extends to each of the threaded holes 214 of the receiving cabin 21 after passing through each of the screw holes 13 of the launching unit 10, and is screwed to the receiving cabin 21, so that the launching unit 10 is locked to the receiving cabin 21 by a group of the screws 100.

[0075] Preferably, continue to refer to the attached Figures 2 to 4The sonar further comprises at least one sealing ring 60, which is fitted on the extension column 11 of the transmitting unit 10 and clamped between the outer wall of the extension column 11 of the transmitting unit 10 and the inner wall of the receiving cabin 21, so that the sealing ring 60 prevents a gap from being generated between the outer wall of the extension column 11 of the transmitting unit 10 and the inner wall of the receiving cabin 21, thereby ensuring the water tightness of the sonar. More preferably, a sealing ring 60 is also provided between the periphery 12 of the transmitting unit 10 and the edge of the hatch 212 of the receiving cabin 21.

[0076] In the attached Figures 1 to 28 In the sonar of the present invention shown, the main control board 24 and the receiving transducer 22 of the receiving unit 20 adopt a separate solution, and the two can be conductively connected through a flexible circuit board (FPC), which makes the design and processing of the receiving transducer 22 independent of the adjustment of the main control board 24. In this way, it is not only conducive to the flexible design of the main control board 24 and the receiving transducer 22, but also during the manufacturing process, even if the main control board 24 is adjusted, it will not affect the receiving transducer 22, or even if the receiving transducer 22 is adjusted, it will not affect the main control board 24, so as to avoid waste caused by the incompatibility between the adjusted main control board 24 and the receiving transducer 22. By allowing the receiving transducer 22 and the main control board 24 to be separated, the installation of the main control board 24 is not affected by the installation of the receiving transducer 22. The debugging of the main control board 24 can be performed before the main control board 24 is accommodated in the accommodating cavity 211 of the receiving cabin 21, so as to facilitate the debugging of the main control board 24.

[0077] At the same time, the main control panel 24 is installed on the bracket 23, and the bracket 23 is locked to the receiving cabin 21, that is, the main control panel 24 is not directly locked to the receiving cabin 21, but is received in the receiving cavity 211 of the receiving cabin 21 through the bracket 23. In this way, it is not only conducive to the reliable installation of the main control panel 24, but also allows the main control panel 24 to be flexibly designed and adjusted, and can avoid the influence of the narrow space of the receiving cavity 211 of the receiving cabin 21 on the installation process, so as to facilitate the manufacture of the sonar.

[0078] In addition, the receiving component 25 is not directly locked to the receiving cabin 21, but is locked to the bracket 23. In this way, the heat generated by the receiving component 25 during operation can be quickly radiated to the receiving cabin 21 through the bracket 23 and dissipated through the receiving cabin 21, which is beneficial to improving the heat dissipation speed of the sonar.

[0079] Since the main control board 24 and the receiving assembly 25 are both mounted on the bracket 23, in order to prevent the main control board 24 from being pressed during the process of mounting the receiving assembly 25 on the bracket 23, refer to the attached Figures 13 to 17 The bracket 23 includes a frame body 231 and two support platforms 232, and the bracket 23 has a frame groove 233. The two support platforms 232 are respectively arranged on opposite sides of the frame body 231, and the frame groove 233 of the bracket 23 is formed between the frame body 231 and the two support platforms 232. For example, the two support platforms 232 extend integrally from opposite sides of the frame body 231 to form the frame groove 233 between the frame body 231 and the two support platforms 232, wherein the main control board 24 is installed on the frame body 231 of the bracket 23 and is located in the frame groove 233 of the bracket 23, and the opposite ends of the receiving component 25 are respectively installed on the two support platforms 232 of the bracket 23. In this way, the two support platforms 232 of the bracket 23 prevent the receiving component 25 from applying pressure to the main control board 24 to protect the main control board 24, so as to improve the reliability of the sonar. Preferably, there is a gap between the receiving component 25 and the main control board 24 .

[0080] Reference Figure 2 , Figures 13 to 17 The receiving cabin 21 has at least one positioning boss 213, and the positioning boss 213 protrudes into the receiving cavity 211 of the receiving cabin 21. The bracket 23 has at least one positioning groove 234, and the positioning groove 234 is located at the connection between the frame 231 and the support platform 232. After the bracket 23 is received in the receiving cavity 211 of the receiving cabin 21 through the hatch 212 of the receiving cabin 21, the positioning boss 213 of the receiving cabin 21 protrudes into the positioning groove 234 of the bracket 23. In this way, on the one hand, the direction in which the bracket 23 is installed in the receiving cabin 21 can be determined. On the other hand, after the bracket 23 is installed in the receiving cabin 21, the bracket 23 is prevented from rotating relative to the receiving cabin 21, thereby ensuring the reliability of the conductive relationship between the receiving transducer 22 and the main control board 24.

[0081] Specifically, in the attached Figures 1 to 28In this example of the sonar of the present invention shown, the number of the positioning bosses 213 of the receiving cabin 21 is two, and the two positioning bosses 213 are symmetrical to each other. Correspondingly, the number of the positioning grooves 234 of the bracket 23 is two, and the two positioning grooves 234 are symmetrical to each other, and the shape and size of the positioning bosses 213 of the receiving cabin 21 match the shape and size of the positioning grooves 234 of the bracket 23, so that the bracket 23 can be reliably locked to the receiving cabin 21.

[0082] Continue to refer to the attached Figure 2 , Figure 3 , Figures 13 to 17 The bracket 23 includes a heat dissipation boss 235, which extends integrally from the bracket body 231 and is located in the bracket groove 233. The main control board chip 241 of the main control board 24 contacts the heat dissipation boss 235 of the bracket 23 through the heat dissipation silicone grease 30. In this way, the heat generated by the main control board chip 241 of the main control board 24 during operation can be directly conducted to the bracket 23, and then conducted to the receiving cabin 21 through the bracket 23. The subsequent heat can be quickly radiated to the outside through the receiving cabin 21 to achieve rapid heat dissipation of the main control board 24. Preferably, the heat dissipation boss 235 of the bracket 23 has a silicone grease groove 2351 for accommodating the heat dissipation silicone grease 30.

[0083] In order to improve the heat dissipation capacity of the main control board chip 241 of the main control board 24, from a material perspective, the material of the bracket 23 can be copper, aluminum, copper alloy or aluminum alloy, so that the bracket 23 has stronger thermal conductivity and relatively low cost. From a structural perspective, the bracket 23 and the receiving cabin 21 need to have a larger contact area, so that the bracket 23 can quickly conduct heat to the receiving cabin 21 and radiate outward through the receiving cabin 21.

[0084] The contact area between the bracket 23 and the receiving chamber 21 can be increased by designing the cross-section of the inner wall of the receiving chamber 21 for defining the accommodating cavity 211 to be circular, and designing the end faces at the opposite ends of the bracket 23 to be arc surfaces, wherein the radius of the circle where the two arc surfaces are located is consistent with the radius of the inner wall of the receiving chamber 21, so that the end faces at the opposite ends of the bracket 23 are in surface contact with the inner wall of the receiving chamber 21, so that the bracket 23 can quickly conduct heat to the receiving chamber 21 and radiate outward through the receiving chamber 21.

[0085] In addition, since the receiving component 25 is directly locked to the bracket 23, the heat generated by the receiving component 25 during operation can be conducted to the bracket 23, and the bracket 23 can quickly conduct the heat to the receiving cabin 21 and radiate outward through the receiving cabin 21. Preferably, in this specific example of the sonar of the present invention, refer to the attached Figure 2 , Figures 6 to 8 The end faces at the opposite ends of the receiving component 25 are arc surfaces, and the radius of the circle where the two arc surfaces are located is consistent with the radius of the inner wall of the receiving cabin 21, so that the end faces at the opposite ends of the receiving component 25 are in surface contact with the inner wall of the receiving cabin 21. In this way, the heat generated by the receiving component 25 during operation can also be directly conducted to the receiving cabin 21 and radiated outward through the receiving cabin 21, so as to greatly improve the heat dissipation capacity of the sonar.

[0086] Continue to attach Figure 6 , Figures 18 to 20 Each of the positioning bosses 213 of the receiving cabin 21 has at least one boss screw hole 2131, and each of the support platforms 232 of the bracket 23 has at least one first support platform screw hole 2321. After the bracket 23 is received in the receiving cavity 211 of the receiving cabin 21 through the hatch 212 of the receiving cabin 21, the position of the first support platform screw hole 2321 of the support platform 232 of the bracket 23 corresponds to the position of the boss screw hole 2131 of the positioning boss 213 of the receiving cabin 21. The sonar further includes at least one locking screw 40, one end of which extends to the boss screw hole 2131 of the positioning boss 213 of the receiving cabin 21 after passing through the first support platform screw hole 2321 of the support platform 232 of the bracket 23, and the end of the locking screw 40 and the positioning boss 213 of the receiving cabin 21 are screwed together, so that the locking screw 40 directly locks the bracket 23 to the receiving cabin 21.

[0087] For example, in the attached Figures 1 to 28 In this specific example of the sonar of the present invention shown, each of the positioning bosses 213 of the receiving cabin 21 has two boss screw holes 2131 respectively, and correspondingly, each of the support platforms 232 of the bracket 23 has two first support platform screw holes 2321 respectively, and one end of each locking screw 40 extends to each boss screw hole 2131 of the positioning boss 213 after passing through each boss screw hole 2131 of the support platform 232 respectively, so that these locking screws 40 can reliably lock the bracket 23 to the receiving cabin 21.

In this way, on the one hand, the sonar can prevent the receiving component 25 from moving in the accommodating cavity 211 of the receiving cabin 21. On the other hand, the sonar allows the end face of the receiving component 25 to fit closely with the inner wall of the receiving cabin 21, so that the heat generated by the receiving component 25 during operation can be quickly conducted to the receiving cabin 21 and radiated outward through the receiving cabin 21, thereby greatly improving the heat dissipation capacity of the sonar.

[0090] Preferably, in the attached Figures 1 to 28 In this specific example of the sonar of the present invention shown, the sonar includes two tightening units 50, which push the receiving component 25 to move laterally at the sides and adjacent to the ends of the receiving component 25, so that the end surface of the receiving component 25 is pressed against the inner wall of the receiving cabin 21.

[0095] The base 2511 of each of the receiving modules 251 respectively has at least one first base through-hole 25114, and at least one of the support platforms 232 of the bracket 23 has a second support platform screw hole 2322. After the tightening unit 50 pushes the receiving component 25 to move laterally, the position of the first base through-hole 25114 of the base 2511 of each of the receiving modules 251 corresponds to the position of the second support platform screw hole 2322 of the support platform 232 of the bracket 23, wherein the sonar includes at least one mounting screw 80, and the bottom of the mounting screw 80 extends to the second support platform screw hole 2322 of the support platform 232 of the bracket 23 after passing through the first base through-hole 25114 of the base 2511 of each of the receiving modules 251 in turn, and is screwed to the support platform 232, so that the mounting screw 80 can reliably mount the receiving component 25 and the bracket 23.

[0096] Preferably, in the attached Figures 1 to 28In the specific example of the sonar of the present invention shown, the bracket screw hole 236 of the bracket 23 is formed at the end of the support platform 232.

[0099] It is worth mentioning that since the respective spring arms 2562 of the butterfly spring piece 256 extend inward and downward from the inner side of the spring ring 2561 in a curved manner, when the bottom end of the assembly screw 255 passes through the spring through hole 2563 of the butterfly spring piece 256, these spring arms 2562 of the butterfly spring piece 256 can guide the assembly screw 255 to smoothly pass through the spring through hole 2563 of the butterfly spring piece 256, and after the ends of the respective spring arms 2562 of the butterfly spring piece 256 move to the position of the slot 2551 of the assembly screw 255, the ends of the respective spring arms 2562 of the butterfly spring piece 256 can automatically snap into the slot 2551 of the assembly screw 255.

[0104] Further, see Attachment Figures 8 to 10The receiving assembly 25 includes a bottom circuit board 257, which is connected to the first connecting circuit board 253 and installed on the base 2511 of the receiving module 251 located at the bottom, and the opposite ends of the bottom circuit board 257 do not extend to the opposite ends of the base 2511. In other words, the opposite ends of the base 2511 of the receiving module 251 located at the bottom are exposed and not covered by the bottom circuit board 257, and the opposite ends of the base 2511 are supported by the two support platforms 232 of the bracket 23, so that the bottom circuit board 257 is suspended on the bracket slot 233 of the bracket 23 to prevent the bottom circuit board 257 from being compressed. Preferably, the bottom circuit board 257 can be locked to the base 2511 of the receiving module 251 at the bottom by a set of screws 100.

[0105] Further, see Attachment Fig. 9 The receiving module 251 includes at least one copper tube 2513, the opposite ends of the copper tube 2513 are respectively placed on the opposite ends of the base 2511, and the middle part of the copper tube 2513 is located above the receiving board chip 25123 of the receiving circuit board 2512, so that the middle part of the copper tube 2513 and the receiving board chip 25123 of the receiving circuit board 2512 are adjacent to each other. In this way, the heat generated by the receiving board chip 25123 of the receiving circuit board 2512 during operation can be quickly conducted to the end of the base 2511 through the copper tube 2513, and directly conducted to the receiving cabin 21 by the end of the base 2511, and heat is dissipated through the receiving cabin 21 to reduce the working temperature of the receiving board chip 25123 of the receiving circuit board 2512.

[0106] Reference Fig. 9 The opposite ends of the base 2511 respectively have at least one copper tube positioning groove 25115, and the copper tube positioning groove 25115 is connected to the base groove 25111. The end of the copper tube 2513 is positioned in the copper tube positioning groove 25115 of the base 2511. In this way, the receiving module 251 can prevent the copper tube 2513 from shifting relative to the receiving circuit board 2512, thereby ensuring that the middle part of the copper tube 2513 is located above the receiving board chip 25123 of the receiving circuit board 2512, so as to ensure the heat dissipation capacity of the sonar.

The thermally conductive adhesive portion 2514 wraps the receiving circuit board 2512 and the copper tube 2513. In this way, on the one hand, the thermally conductive adhesive portion 2514 can fill the gap between the base 2511, the receiving circuit board 2512 and the copper tube 2513, so that the relative positions of the base 2511, the receiving circuit board 2512 and the copper tube 2513 are more stable. On the other hand, the thermally conductive adhesive portion 2514 can quickly conduct the heat generated by the receiving board chip 25123 of the receiving circuit board 2512 during operation to the copper tube 2513 and the base 2511, so as to improve the heat dissipation capacity of the sonar.

Since the bottom of the top block 51 is an inclined surface, the bottom inclined surface 512 of the top block 51 forms the triangular space 200 between the top block 51, the receiving component 25 and the bracket 23. Next, in the process of tightening the tightening screw 52 to rotate the tightening screw 52 relative to the bracket 23, the pushing block 51 is tilted toward the receiving component 25 to push the receiving component 25 to move laterally, so that the end face of the receiving component 25 is pressed against the inner wall of the receiving compartment 21, and at the same time, the position of the mounting screw 80 is moved to the bottom of the mounting screw 80 and corresponds to the second support platform screw hole 2322 of the support platform 232 of the bracket 23.
