The advantage of this setting is that the center of gravity of the hull can be adjusted from multiple angles, so that the unmanned sailboat can travel more smoothly on the water.

[0034] In some embodiments, the driving structure includes a first driving component and a second driving component. The first driving component is used to drive the movable plate 104 to move on the mounting frame 101 ; the second driving component is used to drive the mounting box 102 to slide on the movable plate 104 .

[0035] In some embodiments, the mounting frame 101 includes a slide rail 107, a front baffle 108 and a rear baffle 109. There are two slide rails 107. The front baffle 108 and the rear baffle 109 are respectively installed at the two ends of the slide rail 107. The movable plate 104 is slidably installed between the two slide rails 107, and the movable wheel group 105 is slidably installed on the slide rail 107.

[0036] During actual use, the two slide rails 107 , the front baffle 108 and the rear baffle 109 are connected to form an integrated mounting frame 101 , wherein the movable plate 104 slides between the two slide rails 107 .

[0037] In some embodiments, the first drive assembly includes a motor 110, a ball screw 111 and a screw nut 112. The screw nut 112 is fixedly mounted below the movable plate 104. The motor 110 is fixedly mounted on the rear baffle 109. One end of the screw nut 112 is rotatably connected to the front baffle 108, and the other end is fixedly connected to the output shaft of the motor 110. The screw nut 112 is threadedly connected to the ball screw 111, and the motor 110 is respectively connected to the four sensors 106.

[0038] During actual use, the sensor 106 controls the rotation of the motor 110, and after the motor 110 rotates, it controls the rotation of the ball screw 111. After the ball screw 111 rotates, the screw nut 112 is fixedly connected to the sliding plate. Therefore, when the ball screw 111 rotates, it drives the movable plate 104 to move between the two slide rails 107, thereby enabling the center of gravity adjustment block 103 to move in the vertical direction.

[0039] In some embodiments, the second drive assembly includes a motor 113, a screw 114, a guide rail 115, a slider 116 and a mounting base 117. The mounting base 117 is fixedly mounted on the movable plate 104. The guide rail 115 and the motor 113 are arranged on the mounting base 117. One end of the screw 114 is rotatably connected to the mounting base 117, and the other end is fixedly connected to the output shaft of the motor 113. The slider 116 is slidably mounted on the guide rail 115. The slider 116 is threadedly connected to the screw 114. The slider 116 is fixedly connected to the mounting box 102.

[0040] During actual use, the sensor 106 controls the rotation of the motor 113. After the motor 113 rotates, it drives the screw 114 to rotate. After the screw 114 rotates, it drives the slider 116 to move on the guide rail 115. Since the slider 116 is fixedly connected to the installation box 102, when the slider 116 moves, it drives the installation box 102 to move on the movable plate 104.

[0041] It should be noted that in this embodiment, the sensor 106 controls the rotation of the motor 113 and the motor 110, which is the existing technology. This embodiment does not involve any improvement to the structure of the sensor 106, nor does it involve any improvement to the control method of the sensor 106 on the motor 113 and the motor 110. All of them adopt the existing technology and will not be described in detail here.

[0042] In some embodiments, a guide rod 118 is further provided on the movable plate 104 , and both ends of the guide rod 118 are respectively connected to the two movable wheel groups 105 , and the installation box 102 is slidably engaged with the guide rod 118 .

[0043] In actual use, the purpose of providing the guide rod 118 is to make the installation box 102 more stable when sliding on the movable plate 104 .

[0044] In some embodiments, the clamping structure includes a first clamping plate 119 and a second clamping plate 120. There are two first clamping plates 119 and two second clamping plates 120. The two first clamping plates 119 are used to contact the front and rear end faces of the center of gravity adjustment block 103, and the two second clamping plates 120 are used to contact the left and right end faces of the center of gravity adjustment block 103; the four sides of the installation box 102 are provided with a plurality of threaded holes 121, and the internal threads of the threaded holes 121 are provided with screws 122. The plurality of screws 122 located at the front and rear ends of the center of gravity adjustment block 103 are rotatably connected to the first clamping plate 119, and the plurality of screws 122 located at the left and right ends of the center of gravity adjustment block 103 are rotatably connected to the second clamping plate 120.

[0045] When the center of gravity adjusting block 103 is installed, the staff rotates the screws 122 on the side and front and rear ends of the installation box 102 so that the first clamping plate 119 and the second clamping plate 120 are away from the center position of the installation box 102, and then installs the appropriate center of gravity adjusting block 103 in the installation box 102. After the installation is completed, the screw 122 is reversed so that the first clamping plate 119 and the second clamping plate 120 slowly approach the center of gravity adjusting block 103. As the screw 122 slowly rotates, the first clamping plate 119 and the second clamping plate 120 cooperate to clamp the center of gravity adjusting block 103, thereby completing the installation of the center of gravity adjusting block 103. The advantage of this arrangement is that the center of gravity adjusting blocks 103 of different weights can be configured according to different models of unmanned sailboats, so that the unmanned sailboat has a better effect when performing center adjustment.

[0046] In some embodiments, the guide wheel group includes a mounting plate 123 and a plurality of rollers 124. The plurality of rollers 124 are rotatably mounted on the mounting plate 123. The plurality of rollers 124 also rotatably cooperate with the slide rail 107. The mounting plate 123 is arranged at both ends of the movable plate 104, and the two ends of the guide rod 118 are respectively connected to the two mounting plates 123.

[0047] During actual use, when the movable plate 104 moves between the two slide rails 107, several rollers 124 rotate on the slide rails 107. The purpose of setting the rollers 124 is to convert sliding friction into rolling friction, thereby reducing the friction between the movable plate 104 and the slide rails 107, effectively improving the service life of the movable plate 104.

[0048] In some embodiments, the slide rail 107 is an I-shaped structure, and a sliding area 125 is provided in the middle of the slide rail 107 . The roller 124 is used to slide inside the sliding area 125 .

[0049] In actual use, since the slide rail 107 is an I-shaped structure, the middle position of the slide rail 107 forms a sliding area 125, and the roller 124 can slide inside the sliding area 125 following the moving plate 104.

[0050] In some embodiments, a torsion portion 126 is provided at the end of the screw 122 .

[0051] In actual use, the purpose of providing the twisting portion 126 is to facilitate the staff to rotate the screw 122 more easily, making the screw 122 easier to rotate.
