Detailed implementation mode

[0027] In order to have a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific implementation mode of the present utility model will now be described with reference to the accompanying drawings.

[0028] Example 1: As Figures 1-5 shown, the present utility model provides a technical solution: a self-cooling type unmanned aerial vehicle motor base, including a mounting plate 1, a protective cover 2 arranged below the mounting plate 1, a connecting plate 4 fixedly installed below the mounting plate 1, a mounting sleeve 5 fixedly installed on the right side of the connecting plate 4, an arm 6 arranged inside the mounting sleeve 5, and a connecting component 3 arranged below the mounting plate 1. The connecting component 3 includes a disassembly and assembly mechanism 31 arranged below the mounting plate 1, and a heat dissipation mechanism 32 is arranged below the mounting plate 1. The disassembly and assembly mechanism 31 includes a mounting groove 311 opened on the right side of the mounting sleeve 5, a positioning groove 312 opened on the inner wall of the mounting groove 311, a positioning block 313 fixedly connected to the outer wall of the arm 6, a clamping groove 314 opened on the outer wall of the arm 6, a pressing groove 318 opened on the outer wall of the arm 6, a first inner groove 315 opened on the inner wall of the mounting groove 311, a pressing column 316 sleeved inside the first inner groove 315, a first spring 317 fixedly connected inside the first inner groove 315, a second inner groove 319 opened inside the mounting sleeve 5, a slider 3110 slidably connected inside the second inner groove 319, an inclined surface clamping block 3111 fixedly connected to one side of the slider 3110, a magnet ring 3112 fixedly connected to the inner wall of the second inner groove 319, a second spring 3113 fixedly connected to the inner wall of the second inner groove 319, a connecting rod 3114 fixedly connected to one side of the slider 3110, the outer end of the connecting rod 3114 is rotatably connected to a rotating rod 3115 through a bearing, a positioning rod 3116 is fixedly connected to the inner side of the rotating rod 3115, and a positioning hole 3117 is opened on the outer side of the mounting sleeve 5.

[0029] In this embodiment, one end of the first spring 317 is fixedly connected to the pressing column 316, the pressing column 316 is arranged in pressing contact with the pressing groove 318, and the positioning block 313 is arranged in clamping connection with the positioning groove 312. Through the cooperation of the mounting groove 311, the positioning groove 312, the positioning block 313, the first inner groove 315, the pressing column 316, the first spring 317, and the pressing groove 318, the arm 6 can be assisted in fixing, thereby making it more convenient for manual subsequent further fixing of the arm 6.

[0030] Further, the inclined surface clamping block 3111 movably penetrates through and is clamped with the mounting sleeve 5 and the clamping groove 314. One end of the second spring 3113 is fixedly connected to the slider 3110. The connecting rod 3114 movably penetrates through the mounting sleeve 5. Through the cooperation of the clamping groove 314, the second inner groove 319, the slider 3110, the inclined surface clamping block 3111, the magnet ring 3112, the second spring 3113, the connecting rod 3114, the rotating rod 3115, the positioning rod 3116, and the positioning hole 3117, it is convenient for manual disassembly and assembly of the robotic arm 6, thereby improving the disassembly and assembly efficiency of the mounting sleeve 5 and the robotic arm 6 by the staff.

[0031] Furthermore, the slider 3110 is made of iron material, and the positioning rod 3116 is slidably connected in the positioning hole 3117.

[0032] When the arm 6 needs to be installed, it is only necessary to manually fit the positioning block 313 fixedly connected to the outer wall of the arm 6 with the positioning groove 312, and then insert the arm 6 into the installation groove 311. When the arm 6 moves into the installation groove 311 and contacts the inclined surface clamping block 3111, under the action of the elastic force of the second spring 3113, the inclined surface clamping block 3111 can be moved into the second inner groove 319. Subsequently, when the arm 6 is fully fitted with the installation groove 311, under the action of the elastic force of the first spring 317, the pressing column 316 can be pressed against the pressing groove 318, so as to assist in fixing the arm 6. At the same time, under the action of the elastic force of the second spring 3113, the inclined surface clamping block 3111 can be clamped with the clamping groove 314, so as to achieve the fixing effect on the arm 6. At the same time, when the inclined surface clamping block 3111 is clamped with the clamping groove 314, under the action of the suction force of the magnet ring 3112, the slider 3110 can be attracted to the magnet ring 3112, so that the clamping effect between the inclined surface clamping block 3111 and the clamping groove 314 is better. Even after the installation operation is completed, further, when the arm 6 needs to be disassembled, it is only necessary to manually hold the rotating rod 3115 and pull the connecting rod 3114 outwards, so that the slider 3110 fixedly connected to the inner end of the connecting rod 3114 can move outwards synchronously. Furthermore, the inclined surface clamping block 3111 fixedly connected to one side of the slider 3110 can be separated from the clamping groove 314. And when the rotating rod 3115 moves outwards, the positioning rod 3116 can move outwards synchronously. And when the positioning rod 3116 is separated from the positioning hole 3117, the inclined surface clamping block 3111 and the clamping groove 314 are separated one step earlier. Subsequently, the rotating rod 3115 is rotated manually to drive the positioning rod 3116 to rotate. Subsequently, the inner end of the positioning rod 3116 is arranged in contact with the outer wall of the installation sleeve 5. Subsequently, under the action of the elastic force of the second spring 3113, the positioning rod 3116 can be pressed against the installation sleeve 5. Under the action of the frictional force, the inclined surface clamping block 3111 can stay at a position away from the clamping groove 314. Subsequently, the hand of the operator can be freed, so as to facilitate the separation of the inclined surface clamping block 3111 on the other side from the clamping groove 314. When the inclined surface clamping block 3111 and the clamping groove 314 are completely separated, the arm 6 can be taken out manually.

[0034] In this embodiment, the thread ring 325 is adapted to the annular groove 324. The number of the second heat dissipation holes 326 is several, and they are evenly distributed on the surface of the protective cover 2. Through the cooperation of the first heat dissipation holes 323, the second heat dissipation holes 326 and the protective cover 2, the motor after fixation can be protected. At the same time, when the drone is flying, under the action of air flow, air can pass through the first heat dissipation holes 323 and the second heat dissipation holes 326, so as to achieve the self-cooling effect. Through the cooperation of the annular groove 324 and the thread ring 325, it is convenient for manual disassembly and cleaning of the protective cover 2, and the blockage of the second heat dissipation holes 326 can be prevented, which affects the heat dissipation effect.

[0035] The motor can be installed and fixed through the through hole 321 and the fixing hole 322. Subsequently, the thread ring 325 fixedly connected to the upper part of the protective cover 2 is threadedly connected to the annular groove 324, so that the protective cover 2 can play a protective effect on the motor. At the same time, when the drone is flying, under the action of air flow, air can pass through the first heat dissipation holes 323 and the second heat dissipation holes 326, so as to achieve the self-cooling effect.
