Description

Technical Field

[0001] This utility model relates to a sonar, and more particularly to a sonar and its adapter cover. Background Technology

[0002] Structurally, the sonar includes a launch compartment and a receiver compartment. The launch compartment further includes a launch body and a launch module housed within it. The receiver compartment further includes a receiver body and a receiver module housed within it. To integrate the launch and receiver bodies into a single unit, the sonar further includes an adapter cover. The adapter cover has cover rings at its top and bottom. After the top cover ring is inserted into the launch compartment, a screw can lock the adapter cover onto the launch compartment. The sealing ring of the top cover ring is held between the cover ring and the launch compartment to ensure watertightness. Similarly, after the bottom cover ring is inserted into the receiver compartment, a screw can lock the adapter cover onto the receiver compartment. The sealing ring of the top cover ring is held between the cover ring and the receiver compartment to ensure watertightness. For example, the inventors disclosed such a technology in Chinese invention patent application CN118604791A. However, for sonar, the transmitting and receiving cabins are not always cylindrical. For example, they may be square, trapezoidal, or racetrack-shaped. This means that the cover ring of the adapter cover must also be a non-circular structure, such as square, trapezoidal, or racetrack-shaped. Taking a racetrack-shaped cover ring as an example, after the sealing ring is fitted onto the cover ring, gaps will appear between the sealing ring and the straight edge of the cover ring at the corners at both ends, affecting the watertightness between the adapter cover and the transmitting or receiving cabin. In addition, existing sonar receiving modules require copper pipes for heat dissipation, resulting in complex structures, high costs, and large sizes, which is not conducive to the miniaturization of sonar.

[0041] Refer to the description of this utility model. Figures 1 to 13 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the sonar includes a receiving unit 10, a transmitting unit 20, an adapter cover 30, and at least two sealing rings 40.

[0042] Specifically, the receiving unit 10 includes a receiving chamber 11, a receiving module 12, and a receiving transducer assembly 13. The receiving chamber 11 has a receiving chamber housing cavity 111 and a receiving chamber opening 112 communicating with the receiving chamber housing cavity 111. The receiving module 12 is received in the receiving chamber housing cavity 111 through the receiving chamber opening 112, thereby mounting the receiving module 12 onto the receiving chamber 11. The receiving transducer assembly 13 is disposed in the receiving chamber 11 and connected to the receiving module 12. In a specific example of the sonar of this invention, a set of screws can lock the receiving module 12 onto the receiving chamber 11, so that the receiving module 12 is reliably received in the receiving chamber housing cavity 111 of the receiving chamber 11.

[0043] Reference Appendix Figure 2 The receiving unit 10 further includes a watertight terminal 14, which is installed in the receiving chamber 11 and connected to the receiving module 12. One end of the watertight cable can be connected to the watertight terminal 14.

[0044] The transmitting unit 20 includes a transmitting housing 21, a transmitting module 22, and a transmitting transducer assembly 23. The transmitting housing 21 has a transmitting housing receiving cavity 211 and a transmitting housing opening 212 communicating with the receiving cavity 211. The transmitting module 22 is received in the receiving cavity 211 through the opening 212 to mount the transmitting module 22 onto the transmitting housing 21. The transmitting transducer assembly 23 is disposed on the transmitting housing 21 and connected to the transmitting module 22. In a specific example of the sonar of this invention, a set of screws can lock the transmitting module 22 onto the transmitting housing 21, ensuring that the transmitting module 22 is reliably received in the receiving cavity 211 of the transmitting housing 21.

[0045] The adapter cover 30 has a bottom insertion post 31, a top insertion post 32 and a cover through hole 33. The cover through hole 33 extends from the end face of the top insertion post 32 to the end face of the top insertion post 32, that is, the cover through hole 33 penetrates the opposite sides of the adapter cover 30.

[0046] Both the bottom insertion post 31 and the top insertion post 32 of the adapter cover 30 are fitted with a sealing ring 40. The adapter cover 30 is installed on the receiving chamber 11 by inserting the top insertion post 32 into the receiving chamber cavity 111. The sealing ring 40, fitted onto the top insertion post 32, is clamped between the top insertion post 32 and the receiving chamber 11, preventing a gap from forming between the top insertion post 32 and the receiving chamber 11. The adapter cover 30 is installed on the transmitting chamber 21 by inserting the top insertion post 32 into the transmitting chamber cavity 211. The sealing ring 40, fitted onto the top insertion post 32, is clamped between the top insertion post 32 and the transmitting chamber 21, preventing a gap from forming between the top insertion post 32 and the transmitting chamber 21. The receiving module 12 and the transmitting module 22 can be connected through the cover perforation 33 of the adapter cover 30.

[0047] It is worth mentioning that the installation method of the adapter cover 30 and the receiving cabin 11 is not limited in the sonar of this utility model. For example, a set of screws can be used to install the adapter cover 30 onto the receiving cabin 11, so that the adapter cover 30 and the receiving cabin 11 are reliably installed. Correspondingly, the installation method of the adapter cover 30 and the transmitting cabin 21 is not limited in the sonar of this utility model. For example, a set of screws can be used to install the adapter cover 30 onto the transmitting cabin 21, so that the adapter cover 30 and the transmitting cabin 21 are reliably installed.

[0048] Preferably, a sealing ring 40 may also be provided between the rim of the receiving chamber 11 and the lower surface of the adapter cover 30 near the top insertion post 32 to further increase the water tightness of the mounting positions of the receiving chamber 11 and the adapter cover 30. Similarly, a sealing ring 40 may also be provided between the rim of the transmitting chamber 21 and the upper surface of the adapter cover 30 near the top insertion post 32 to further increase the water tightness of the mounting positions of the transmitting chamber 21 and the adapter cover 30.

[0049] In the sonar of this utility model, the receiving chamber 11 is non-cylindrical. To adapt to the shape of the receiving chamber 11, the bottom insertion post 31 of the adapter cover 30 is also non-cylindrical. The bottom insertion post 31 of the adapter cover 30 has at least three bottom sidewalls 311. The connection between two adjacent bottom sidewalls 311 is rounded. Each bottom sidewall 311 is an outwardly convex arc shape. In this way, the sonar can ensure that each part of the sealing ring 40 is tightly bound to the bottom insertion post 31 of the adapter cover 30, avoiding gaps between the sealing ring 40 and the bottom insertion post 31 of the adapter cover 30, thereby helping to ensure the watertightness of the sonar.

[0050] For example, in the appendix Figures 1 to 13 In this specific example of the sonar of the present invention shown, the receiving chamber 11 has a generally trapezoidal structure, and correspondingly, the bottom insertion post 31 of the adapter cover 30 is generally trapezoidal. The bottom sidewall 311 of the bottom insertion post 31 of the adapter cover 30 has a first bottom sidewall 3111, a second bottom sidewall 3112, a third bottom sidewall 3113, and a fourth bottom sidewall 3114. The positions of the first bottom sidewall 3111 and the third bottom sidewall 3113 are opposite each other, and the positions of the second bottom sidewall 3112 and the fourth bottom sidewall 3114 are opposite each other. The connection between the first bottom sidewall 3111 and the second bottom sidewall 3112 is rounded. The second bottom sidewall 3112... The connection between the bottom third sidewall 3113 and the bottom fourth sidewall 3114 is rounded, the connection between the bottom fourth sidewall 3114 and the bottom first sidewall 3111 is rounded, and the bottom first sidewall 3111, the bottom second sidewall 3112, the bottom third sidewall 3113 and the bottom fourth sidewall 3114 are all convex arc shapes. Thus, after the sealing ring 40 is fitted onto the bottom insertion post 31 of the adapter cover 30, the sonar can prevent gaps from forming between the sealing ring 40 and the bottom first sidewall 3111, the bottom second sidewall 3112, the bottom third sidewall 3113 and the bottom fourth sidewall 3114. It is understandable that, since the connection between the two adjacent bottom sidewalls 311 of the bottom insertion post 31 of the adapter cover 30 is rounded, there is no gap at the connection between the sealing ring 40 and the two adjacent bottom sidewalls 311.

[0051] In the sonar of this invention, the launch chamber 21 is non-cylindrical. To accommodate the shape of the launch chamber 21, the top insertion post 32 of the adapter cover 30 is also non-cylindrical. The top insertion post 32 of the adapter cover 30 has at least three top sidewalls 321. The connection between two adjacent top sidewalls 321 is rounded, and each top sidewall 321 is an outwardly convex arc. In this way, the sonar can ensure that each part of the sealing ring 40 is tightly bound to the top insertion post 32 of the adapter cover 30, avoiding gaps between the sealing ring 40 and the top insertion post 32 of the adapter cover 30, thereby helping to ensure the watertightness of the sonar.

[0052] For example, in the appendix Figures 1 to 13 In this specific example of the sonar of the present invention shown, the launch chamber 21 has a generally runway-shaped structure, and correspondingly, the top insertion post 32 of the adapter cover 30 is also generally runway-shaped. The top sidewall 321 of the top insertion post 32 of the adapter cover 30 has a first top sidewall 3211, a second top sidewall 3212, a third top sidewall 3213, and a fourth top sidewall 3214. The positions of the first top sidewall 3211 and the third top sidewall 3213 are opposite each other, and the positions of the second top sidewall 3212 and the fourth top sidewall 3214 are opposite each other. The connection between the first top sidewall 3211 and the second top sidewall 3212 is reversed. The joints of the top second sidewall 3212 and the top third sidewall 3213 are rounded, the joints of the top third sidewall 3213 and the top fourth sidewall 3214 are rounded, and the joints of the top fourth sidewall 3214 and the top first sidewall 3211 are rounded. Furthermore, both the top first sidewall 3211 and the top third sidewall 3213 are convex arc shapes. Thus, after the sealing ring 40 is fitted onto the top insertion post 32 of the adapter cover 30, the sonar can prevent gaps from forming between the sealing ring 40 and the top first sidewall 3211, the top second sidewall 3212, the top third sidewall 3213, and the top fourth sidewall 3214. It is understandable that, since the connection between the two adjacent top sidewalls 321 of the top insertion post 32 of the adapter cover 30 is rounded, there is no gap at the connection between the sealing ring 40 and the two adjacent top sidewalls 321.

[0053] Preferably, the top insertion post 32 of the adapter cover 30 has a bottom groove 312 surrounding the top insertion post 32, and the sealing ring 40 is located in the bottom groove 312 of the top insertion post 32. Thus, after the adapter cover 30 is installed on the receiving chamber 11, the sealing ring 40 fitted onto the top insertion post 32 can be reliably held between the top insertion post 32 and the receiving chamber 11. Correspondingly, the top insertion post 32 of the adapter cover 30 has a top groove 322 surrounding the top insertion post 32, and the sealing ring 40 is located in the top groove 322 of the top insertion post 32. Thus, after the adapter cover 30 is installed on the launching chamber 21, the sealing ring 40 fitted onto the top insertion post 32 can be reliably held between the top insertion post 32 and the launching chamber 21.

[0054] Furthermore, the sonar includes a connecting plate 50, which is mounted on the bottom of the adapter cover 30. The bottom of the transmitting module 22 extends into the cover perforation 33 of the adapter cover 30 and is mounted on the connecting plate 50. Thus, the transmitting module 22 can be reliably housed within the receiving cavity 211 of the transmitting chamber 21, preventing the transmitting module 22 from shaking within the transmitting chamber 21. (See attached...) Figures 1 to 13 In this specific example of the sonar of the present invention shown, a set of screws can be used to mount the connecting plate 50 to the bottom of the adapter cover 30, and a set of screws can also be used to mount the bottom of the transmitting module 22 to the connecting plate 50.

[0055] Preferably, the adapter cover 30 has a pair of slots 34, which are connected to the opposite sides of the cover perforation 33. The opposite sides of the bottom of the transmitting module 22 are respectively inserted into the pair of slots 34 of the adapter cover 30. In this way, during the assembly of the sonar, the adapter cover 30 can position the bottom of the transmitting module 22. After the sonar is assembled, the adapter cover 30 can ensure the stability of the bottom of the transmitting module 22 and prevent the transmitting module 22 from shaking inside the transmitting chamber 21.

[0056] Reference Appendix Figure 3 , Figure 5 , Figures 10 to 13 The receiving module 12 includes at least two circuit board assemblies 121, which are stacked together.

[0057] Specifically, each of the circuit board assemblies 121 includes a bottom cover 1211 and at least one circuit board 1212. The bottom cover 1211 has at least one slot 12111. The circuit board 1212 is installed in the slot 12111 of the bottom cover 1211 through the slot opening of the slot 12111. For example, a set of screws can be used to lock the circuit board 1212 into the slot 12111 of the bottom cover 1211, so that the relative position of the circuit board 1212 and the bottom cover 1211 remains unchanged.

[0058] Preferably, the bottom cover 1211 further has at least one side notch 12112, the side notch 12112 communicating with the plate groove 12111, wherein the circuit board 1212 has a terminal 12121, the terminal 12121 extending to the plate groove 12111 of the bottom cover 1211, so as to facilitate the subsequent connection of the circuit board 1212 to other components.

[0059] In the appendix Figures 1 to 13 In this specific example of the sonar of the present invention shown, the bottom cover 1211 has two plate slots 12111 and two side notches 12112. The two plate slots 12111 are arranged side by side, one side notch 12112 communicates with one plate slot 12111, and the other side notch 12112 communicates with the other plate slot 12111. Correspondingly, the circuit board assembly 121 includes two circuit boards 1212, one circuit board 1212 is mounted in one plate slot 12111 of the bottom cover 1211, and the other circuit board 1212 is mounted in the other plate slot 12111 of the bottom cover 1211. It is understood that since the two plate slots 12111 of the bottom cover 1211 are side by side, the two circuit boards 1212 are also side by side.

[0060] Continue to refer to the appendix Figures 10 to 13The bottom cover 1211 of the upper circuit board assembly 121 closes the slot 12111 of the bottom cover 1211 of the lower circuit board assembly 121. Furthermore, the heat dissipation protrusion 12113 of the bottom cover 1211 of the upper circuit board assembly 121 protrudes towards the chip 12122 of the circuit board 1212 of the lower circuit board assembly 121. In this way, the circuit board 1212 of the lower circuit board assembly 121 is hidden between the two stacked bottom covers 1211. Thus, the two bottom covers 1211 cooperate to protect the circuit board 1212. On the other hand, since the heat dissipation protrusion 12113 of the bottom cover 1211 of the upper circuit board assembly 121 protrudes toward the chip 12122 of the circuit board 1212 of the lower circuit board assembly 121, the heat generated by the chip 12122 during operation can be quickly conducted to the upper bottom cover 1211 through the heat dissipation protrusion 12113, and dissipated through the bottom cover 1211, thereby improving the heat dissipation efficiency of the receiving module 12.

[0061] In the sonar of this utility model, by providing a heat dissipation protrusion 12113 at the bottom of the upper bottom cover 1211 and allowing this heat dissipation protrusion 12113 to be adjacent to the chip 12122 of the lower circuit board 1212, the receiving module 12 can ensure the heat dissipation efficiency of the receiving module 12 without configuring copper pipes. In this way, not only can the assembly steps of the receiving module 12 be reduced, but the receiving module 12 can also be made more compact and smaller, which is conducive to realizing the lightweighting and miniaturization of the sonar.

[0062] Preferably, the heat dissipation protrusion 12113 of the bottom cover 1211 of the upper circuit board assembly 121 protrudes into the board groove 12111 of the bottom cover 1211 of the lower circuit board assembly 121, so that the heat dissipation protrusion 12113 is adjacent to the chip 12122 of the lower circuit board assembly 1212. Preferably, thermally conductive silicone is provided between the heat dissipation protrusion 12113 of the bottom cover 1211 of the upper circuit board assembly 121 and the chip 12122 of the circuit board 1212 of the lower circuit board assembly 121 to improve heat conduction efficiency.

[0063] In this specific example of the sonar of this utility model, the bottom cover 1211 can be made of aluminum alloy, giving it high strength, light weight, and good heat dissipation. Furthermore, in this embodiment, the bottom cover 1211 can be manufactured using a milling process; that is, the plate groove 12111, the side notch 12112, and the heat dissipation boss 12113 can be formed on the bottom cover 1211 through milling.

[0064] Preferably, the bottom cover 1211 further has a connecting groove 12114, which connects the two plate slots 12111. The connecting groove 12114 of the lower bottom cover 1211 is used to avoid the heat dissipation protrusion 12113 of the upper bottom cover 1211, so that the heat dissipation protrusion 12113 of the upper bottom cover 1211 can extend from one plate slot 12111 of the lower bottom cover 1211 to the other plate slot 12111. In this way, the heat dissipation protrusion 12113 of the upper bottom cover 1211 can simultaneously dissipate heat for the chips 12122 of the two circuit boards 1212 located below.

[0065] In the appendix Figures 1 to 13 In this specific example of the sonar of the present invention shown, the length dimension of the bottom cover 1211 of the lowermost circuit board assembly 121 is slightly larger than the length dimension of the bottom covers 1211 of the other circuit board assemblies 121. In this way, the screw can lock the bottom cover 1211 of the lowermost circuit board assembly 121 to the receiving chamber 11, so as to install the receiving module 12 in the receiving chamber receiving cavity 111 of the receiving chamber 11.

[0066] In the appendix Figures 1 to 13In this specific example of the sonar of the present invention shown, the receiving module 12 includes four circuit board assemblies 121. The bottom covers 1211 of the three upper circuit board assemblies 121 each have at least one screw through hole 12115 at opposite ends. The bottom cover 1211 of the lowermost circuit board assembly 121 each has at least one threaded hole 12116 at opposite ends. The screw through holes 12115 of the bottom covers 1211 of the three upper circuit board assemblies 121 are located... The positions of the threaded holes 12116 of the bottom cover 1211 of the lowermost circuit board assembly 121 are opposite to those of the uppermost circuit board assembly 121. One end of the screw extends from the threaded holes 12115 of the bottom covers 1211 of the uppermost three circuit board assemblies 1211 to the threaded hole 12116 of the bottom cover 1211 of the lowermost circuit board assembly 121, and the screw is screwed onto this bottom cover 1211. Thus, the four circuit board assemblies 121 are reliably installed. It is understood that in other examples of the sonar of this invention, the number of circuit board assemblies 121 may be three or more, depending on the specific type of sonar.

[0067] Furthermore, each of the circuit board assemblies 121 has a pin hole 12117 at each of its opposite ends of the bottom cover 1211. The receiving module 12 further includes two positioning pins 122. One positioning pin 122 is inserted into the pin hole 12117 at one end of the bottom cover 1211, and the other positioning pin 122 is inserted into the pin hole 1117 at the other end of the bottom cover 1211. By providing the pin hole 1117 at the end of each bottom cover 1211 and allowing the positioning pin 122 to be inserted into the pin hole 12117 of the bottom cover 1211, it is beneficial to ensure that the screw through hole 12115 and the threaded hole 12116 of the bottom cover 1211 are aligned during the assembly of each circuit board assembly 121, thereby facilitating the subsequent fixing of the bottom covers 1211 together with screws.
