[0055] Refer to the attached drawings of the specification of this utility model Figures 1 to 19 A foldable positioning array according to a preferred embodiment of the utility model will be disclosed and explained in the following description, wherein the positioning array has a folded state and an unfolded state, and the positioning array can switch between the folded state and the unfolded state. When the positioning array is in the folded state, the positioning array has a smaller size in both the horizontal and height directions, so that the positioning array is convenient for storage and transportation. When the positioning array is in the unfolded state, the positioning array submerged in water can be used to locate underwater targets.

[0056] Specifically, the positioning array includes a watertight cylinder 10, a first transducer assembly 20, at least three second transducer assemblies 30 and at least three extension arms 40. Each of the extension arms 40 has a hinged end 41 and a free end 42 relative to the hinged end 41, wherein the hinged end 41 of each extension arm 40 is hinged to the watertight cylinder 10, so that each extension arm 40 can rotate relative to the watertight cylinder 10, and the free end 42 of each extension arm 40 is respectively provided with one of the second transducer assemblies 30, wherein the first transducer assembly 20 is arranged at the bottom of the watertight cylinder 10. By driving the hinged ends 41 of the extension arms 40 to rotate relative to the watertight cylinder 10, the positioning array switches between the folded state and the unfolded state, wherein when the positioning array is in the unfolded state, the extension direction of the extension arms 40 is perpendicular to the extension direction of the watertight cylinder 10, and the submerged positioning array can be used to locate underwater targets, and when the positioning array is in the folded state, the extension arms 40 surround the sides of the watertight cylinder 10, therefore, relative to the umbrella-shaped telescopic hydroacoustic positioning array of the prior art, the positioning array of the utility model has a smaller height dimension when in the folded state, making the positioning array convenient for storage and transportation. That is to say, the positioning array in the folded state has smaller dimensions in both the horizontal and height directions, making the positioning array convenient for storage and transportation.

[0057] The bottom end of the watertight cylinder 10 has at least three bosses 11, and the hinged end 41 of each extension arm 40 is hinged to each boss 11 respectively, so that the hinged end 41 of the extension arm 40 is hinged to the bottom end of the watertight cylinder 10, thereby enabling the hinged end 41 of the extension arm 40 to rotate relative to the watertight cylinder 10. The boss 11 of the watertight cylinder 10 has a locking top surface 111 and a locking side surface 112, wherein the positioning matrix further includes at least three locking members 50, each of which has a supporting surface 51, and the locking member 50 is movably mounted on the hinged end 41 of the extension arm 40, wherein after the positioning matrix switches from the expanded state to the folded state, the locking member 50 is moved to a position where the supporting surface 51 of the locking member 50 and the locking top surface 111 of the boss 11 are in surface contact, so that the positioning matrix is ​​stably maintained in the folded state, and accordingly, after the positioning matrix switches from the folded state to the expanded state, the locking member 50 is moved to a position where the supporting surface 51 of the locking member 50 and the locking side surface 112 of the boss 11 are in surface contact, so that the positioning matrix is ​​stably maintained in the expanded state.

[0058] In order to facilitate the movement of the locking member 50 and to ensure that the locking member 50 can be stably maintained at the moved position, Figures 1 to 19In this specific example of the positioning matrix of the present invention shown, the locking member 50 is screwed to the hinged end 41 of the extension arm 40, and the locking member 50 is able to move along the extension direction of the extension arm 40 by rotating the locking member 50 to achieve locking and unlocking of the extension arm 40, wherein when the locking member 50 moves along the extension direction of the extension arm 40 to a position where the abutment surface 51 of the locking member 50 and the locking top surface 111 of the boss 11 are in surface contact, the locking member 50 locks the extension arm 40 to prevent the hinged end 41 of the extension arm 40 from rotating relative to the watertight cylinder 10, thereby stably maintaining the positioning matrix in the folded state, and when the locking member 50 moves along the extension direction of the extension arm 40 to a position where the abutment surface 51 of the locking member 50 is away from the locking top surface 111 of the boss 11, the locking member 50 unlocks the extension arm 40 to allow The hinged end 41 of the extension arm 40 rotates relative to the watertight cylinder 10, so that the positioning matrix can be switched from the folded state to the unfolded state. When the locking member 50 moves along the extension direction of the extension arm 40 to the position where the abutment surface 51 of the locking member 50 and the locking side surface 112 of the boss 11 are in surface contact, the locking member 50 locks the extension arm 40 to prevent the hinged end 41 of the extension arm 40 from rotating relative to the watertight cylinder 10, so that the positioning matrix is ​​stably maintained in the unfolded state. When the locking member 50 moves along the extension direction of the extension arm 40 to the position where the abutment surface 51 of the locking member 50 is away from the locking side surface 112 of the boss 11, the locking member 50 unlocks the extension arm 40 to allow the hinged end 41 of the extension arm 40 to rotate relative to the watertight cylinder 10, so that the positioning matrix can be switched from the unfolded state to the folded state.

[0059] Specifically, the locking member 50 has an internal thread structure, and the hinged end 41 of the extension arm 40 has an external thread structure. The internal thread structure of the locking member 50 and the external thread structure of the hinged end 41 of the extension arm 40 cooperate with each other, so that the locking member 50 is screwed to the hinged end 41 of the extension arm 40, so that the locking member 50 can be allowed to move along the extension direction of the extension arm 40 toward or away from the boss 11 of the watertight cylinder 10 by rotating the locking member 50.

[0060] Further, the boss 11 of the watertight cylinder 10 includes a left boss 113 and a right boss 114 and has a hinge groove 115, the left boss 113 and the right boss 114 are spaced apart from each other to form the hinge groove 115 between the left boss 113 and the right boss 114, a portion of the locking top surface 111 of the boss 111 is formed on the left boss 113, and another portion is formed on the right boss 114, a portion of the locking side surface 112 of the boss 11 is formed on the left boss 113, and another portion is formed on the right boss 114, wherein the hinge end 41 of the extension arm 40 extends to the hinge groove 115 of the boss 11. 5, and the two opposite sides of the hinged end 41 of the extension arm 40 are hinged to the left boss 113 and the right boss 114 respectively. In this way, on the one hand, when the locking member 50 unlocks the extension arm 40 and allows the hinged end 41 of the extension arm 40 to rotate relative to the watertight cylinder 10, the extension arm 40 is prevented from being deflected, so as to ensure that each of the second transducer assemblies 30 after being deployed is in the designed position; on the other hand, after the locking member 50 locks the extension arm 40, the locking member 50 and the left boss 113 and the right boss 114 cooperate with each other to prevent the extension arm 40 from being deflected, so as to ensure that each of the second transducer assemblies 30 after being deployed is in the designed position.

[0061] Furthermore, the left side boss 113 of the boss 11 of the watertight cylinder 10 has a left side through hole 1131 connected to the hinge groove 115, the right side boss 114 has a right side through hole 1141 connected to the hinge groove 115, and the extension arm 40 has an arm body through hole 43 at the hinge end 41, and the position of the arm body through hole 43 of the extension arm 40 corresponds to the position of the left side through hole 1131 of the left side boss 113 and the position of the right side through hole 1141 of the right side boss 114. The positioning matrix further includes at least three pins 60, which simultaneously penetrate the left through hole 1131 of the left boss 113, the arm body through hole 43 of the extension arm 40, and the right through hole 1141 of the right boss 114, and the end of the pin 60 is rotatable relative to the boss 11 and / or the middle of the pin 60 is rotatable relative to the hinge end 41 of the extension arm 40, so that the opposite sides of the hinge end 41 of the extension arm 40 are respectively hinged to the left boss 113 and the right boss 114. It can be understood that when the locking member 50 unlocks the extension arm 40, the extension arm 40 can rotate relative to the watertight cylinder 10 around the central axis of the pin 60, so that the positioning matrix is ​​switched between the folded state and the unfolded state.

[0062] In the attached Figures 1 to 19 In the example of the positioning matrix of the utility model shown, the positioning matrix includes at least three abutting members 70, the outer side of each abutting member 70 has an abutting surface 71, and each abutting member 70 is located in the hinge groove 115 of the boss 11 of the watertight cylinder 10, wherein when the positioning matrix is ​​switched from the folded state to the unfolded state, the end surface of the hinge end 41 of the extension arm 40 is abutted by the abutting surface 71 of the abutting member 70 to limit the rotation position of the extension arm 40, so that the extension arm 40 can be maintained at a position where the extension direction of the extension arm 40 is perpendicular to the extension direction of the watertight cylinder 10. In other words, the abutting member 70 is used to limit the maximum rotation position of the extension arm 40.

[0063] It is worth mentioning that the specific manner in which the support member 70 is arranged in the hinge groove 115 of the boss 11 of the watertight cylinder 10 is not limited in the positioning matrix of the utility model. Figures 1 to 19 In this specific example of the positioning matrix of the utility model shown, the support member 70 is installed at the bottom end of the watertight cylinder 10, so that the support member 70 is set in the hinge groove 115 of the boss 11 of the watertight cylinder 10. Optionally, in other specific examples of the positioning matrix of the utility model, the support member 70 and the watertight cylinder 10 are integrated, that is, the support member 70 is integrally formed at the bottom end of the watertight cylinder 10, so that the support member 70 is set in the hinge groove 115 of the boss 11 of the watertight cylinder 10.

[0064] Further, the first transducer assembly 20 includes a first bracket 21 and a first transducer 22 arranged on the first bracket 21, the first bracket 21 has a first bracket through-hole 211, the first bracket 21 is fixedly arranged on the bottom of the watertight cylinder 10, and the first bracket through-hole 211 of the first bracket 21 faces the bottom of the watertight cylinder 10, wherein the positioning array includes a first cable 80, the first cable 80 extends from the bottom of the watertight cylinder 10 through the first bracket through-hole 211 of the first bracket 21 to the first transducer 22, so that the watertight cylinder 10 and the first transducer 22 are connected by the first cable 80, so as to realize signal transmission between the watertight cylinder 10 and the first transducer 22.

[0065] Further, the second transducer assembly 30 is hinged to the free end 42 of the extension arm 40, so that the second transducer assembly 30 is rotatable relative to the extension arm 40, wherein the posture of the second transducer assembly 30 can change with the state of the positioning array. For example, when the positioning array is in the folded state, the second transducer assembly 30 can be rotated to a position where the extension direction of the second transducer assembly 30 is consistent with the extension direction of the extension arm 40, so as to further reduce the size of the positioning array in the horizontal direction; when the positioning array is in the unfolded state, the second transducer assembly 30 can be rotated to a position where the extension direction of the second transducer assembly 30 is perpendicular to the extension direction of the extension arm 40, so that the second transducer assembly 30 and the first transducer assembly 20 cooperate with each other to realize the positioning of the underwater target.

[0066] Specifically, the second transducer assembly 30 includes a second bracket 31 and a second transducer 32 arranged on the second bracket 31, and one side of the end of the second bracket 31 is hinged to the free end 42 of the extension arm 40, so that the second transducer assembly 30 can rotate relative to the extension arm 40.

[0067] Preferably, the extension arm 40 has an arm channel 44, a side opening 45 and an end opening 46, the side opening 45 is connected to the arm channel 44 at the side of the hinge end 41 of the extension arm 40, and the end opening 46 is connected to the arm channel 44 at the end of the free end 42 of the extension arm 40, wherein the second bracket 31 has a second bracket through-hole 311, and the second bracket through-hole 311 of the second bracket 31 and the end opening 46 of the extension arm 40 are offset.
