[0002] The brushless motor is a high-efficiency, high-power output electric motor that is widely used in various mechanical equipment, such as models, aircraft, industrial robots, etc. However, due to its high-speed rotation, it generates a lot of heat. If the heat cannot be effectively dissipated, it will seriously affect the life and performance of the motor.

[0003] Existing cooling devices for brushless motors generally only use air cooling or water cooling, and cannot perform all-round cooling of the brushless motor. The cooling area is small and the cooling effect is limited. In addition, the use and disassembly of the cooling devices for brushless motors are also relatively troublesome and have many restrictions.

[0004] Therefore, a cooling device for a brushless motor that is easy to install and disassemble is needed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing cooling device for brushless motor, which has limited cooling effect and is complicated to install and disassemble, the utility model provides a cooling device for brushless motor that is easy to install and disassemble.

The bracket is slidably connected to the brushless motor, the bracket is slidably connected to the latch, an elastic member is fixedly connected between the latch and the bracket, and the bracket is provided with a cooling component for cooling.

[0007] As an improvement of the above solution, the cooling component includes a condensation box, a water pipe and a water pump. The bracket is fixedly connected to the water pipe, the water pipe is fixedly connected to the condensation boxes distributed in pairs, and the water pump is fixedly connected between the paired condensation boxes.

[0008] As an improvement of the above scheme, it also includes fan blades, a fan, a top plate, a first connecting rod, a spring and a belt. The fan is fixedly connected to the bracket, and the bracket is rotatably connected to the fan blades that are equidistantly distributed longitudinally. The fan blades on the same side are driven by a belt. The fan blades are fixedly connected to the diagonally distributed first connecting rod. The bracket and the first connecting rod are connected by a spring. The output end of the brushless motor is fixedly connected to the top plate. When the top plate rotates to contact the first connecting rod, it will drive the first connecting rod to rotate until the top plate is separated from the first connecting rod.

[0009] As an improvement of the above solution, it also includes an air guide plate and a second connecting rod, the bracket is fixedly connected to the second connecting rod, and the second connecting rod is fixedly connected to the air guide plate.

[0010] As an improvement of the above solution, it also includes a clamping block, and the paired condensing boxes are fixedly connected with the clamping block.

[0011] As an improvement of the above solution, the air guide plate is designed to be arc-shaped and is used to control the direction, speed and distribution of the airflow so that the airflow can pass through the brushless motor evenly.

[0012] Compared with the prior art, the utility model has the following advantages: the utility model makes it very convenient to install and disassemble the cooling device for the brushless motor by means of the latch, the clamping block and the foldable and detachable bracket.

[0013] The utility model starts a water pump to drive water or condensate in a condensation box to circulate in a water pipe, thereby cooling the surroundings of the brushless motor.

[0014] The utility model starts the fan to carry out air cooling and cooling on the front and rear sides of the brushless motor. The fan blades can slow down and guide the airflow, so that the top and bottom of the brushless motor can also be cooled by the air.

DETAILED DESCRIPTION

[0022] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1: A cooling device for a brushless motor, such as Figure 1 and Figure 2 As shown, it includes a brushless motor 1, a bracket 11, a latch 12, and an elastic member 13. The brushless motor 1 is slidably connected inside the bracket 11, and the latch 12 is slidably connected to the top of the bracket 11. The latch 12 is used to fix the folded bracket 11, and an elastic member 13 is fixed between the latch 12 and the bracket 11.

[0024] It also includes a clamping block 23, which is fixedly connected to the right side of the paired condensing boxes 2, and is used to fix the paired condensing boxes.

[0025] When people need to use the cooling device, first pull the latch 12 upwards, the elastic member 13 is compressed, and after the brushless motor 1 is closed and fixed with the bracket 11, release the latch 12, the elastic member 13 is reset, and drives the latch 12 to move downward into the hole, fix the closed bracket 11, and at the same time move the block 23 forward to connect the paired condensation boxes 2, and complete the installation of the cooling device; after the device is used, pull the latch 12 upwards, move the block 23 backwards, separate the closed bracket 11 and the condensation box 2, and complete the disassembly of the cooling device.

[0026] Embodiment 2: Based on embodiment 1, Figure 3 As shown, it also includes a condensation box 2, a water pipe 21 and a water pump 22. The bracket 11 is fixedly connected to an axially distributed water pipe 21. Both ends of the axially distributed water pipe 21 are respectively fixedly connected to paired condensation boxes 2. The condensation boxes 2 are used to store water or condensate. A water pump 22 is fixedly connected between the paired condensation boxes 2. The water pump 22 is used to drive the liquid in the condensation box 2 to circulate in the water pipe 21.

[0027] When the motor needs to be cooled during operation, the water pump 22 can be started to drive the water or condensate in the condensation tank 2 to circulate in the water pipe 21 to cool the surrounding areas of the brushless motor 1.

[0028] like Figure 4 and Figure 5 As shown, it also includes fan blades 3, fan 31, top plate 32, first connecting rod 33, spring 34 and belt 35. Fan 31 is fixedly connected to the front and rear sides of the bracket 11. Fan blades 3 are rotatably connected to the front and rear sides of the bracket 11 with equidistant longitudinal distribution. The fan blades 3 are used to decelerate and guide the airflow. The fan blades 3 on the same side are driven by belt 35. A diagonally distributed first connecting rod 33 is fixedly connected to the right side of the fan blade 3. The bracket 11 and the first connecting rod 33 are connected by a spring 34. The output end of the brushless motor 1 is fixedly connected to the top plate 32. When the top plate 32 rotates to contact with the first connecting rod 33, it will drive the first connecting rod 33 to rotate until the top plate 32 is separated from the first connecting rod 33.

[0029] like Figure 6 As shown, it also includes an air guide plate 4 and a second connecting rod 41. The second connecting rod 41 is fixedly connected to the upper left side of the bracket 11, and the air guide plate 4 is fixedly connected to the left side of the second connecting rod 41. The air guide plate 4 is used to guide the airflow to cool the left side of the brushless motor 1.

[0030] When the motor overheats and needs to be cooled, people can also start the fan 31 to cool the front and rear sides of the brushless motor 1. To prevent cold wind from blowing directly and reduce air convection, the fan blades 3 can slow down and guide the airflow. When the motor rotates clockwise, it drives the top plate 32 to rotate clockwise. When the top plate 32 rotates to contact the first connecting rod 33, it drives the first connecting rod 33 on the lower side to move upward, and drives the first connecting rod 33 on the upper side to move downward. The spring 34 is stretched, and the fan blades 3 on the same side rotate counterclockwise under the transmission action of the belt 35. The front fan blades 3 guide the airflow to the top of the brushless motor 1, and the rear fan blades 3 guide the airflow to the bottom of the brushless motor 1, so that the top and bottom of the brushless motor 1 can also be cooled by air. The existence of the air guide plate 4 can guide the airflow to cool the left side of the brushless motor 1, thereby realizing all-round air cooling of the brushless motor 1.
