When the temperature sensor 5 detects that the temperature threshold in the driving bin 2 reaches F1, a signal is sent to the air cylinder 701, the air cylinder 701 controls the movement of the docking seat 702 and the docking head 703 and moves close to the docking disc 604 until the docking head 703 is inserted into the docking groove 605 (it is worth noting that during the process that the air cylinder 701 drives the docking seat 702 and the docking head 703 to move close to the docking disc 604, the driving gear 402 is in a rotating state, therefore, the docking head 703 entering the docking groove 605 is divided into two cases, one is that the docking head 703 is aligned with the docking groove 605, and the docking head 703 is directly inserted into the docking groove 605; the other is that the docking head 703 is not aligned with the docking groove 605, the docking head 703 first contacts the surface of the docking disc 604 and is subjected to resistance, the docking head 703 is pressed into the docking seat 702 through the buffer spring 704, with the rotation of the driving gear 402, the docking head 703 is slowly aligned with the docking groove 605, the buffer spring 704 ejects the docking head 703 from the docking seat 702 and inserts it into the docking groove 605), with the rotation of the driving gear 402 driving the docking head 703, the docking head 703 will contact one end of the docking groove 605 to form a limit, the rotating docking head 703 will drive the docking disc 604 to rotate and drive the movable sleeve 601, the linkage bevel gear 602 and the linkage gear 603 to rotate, through the engagement transmission of the linkage bevel gear 602 and the transmission bevel gear 902, the transmission rod 901 and the primary transmission gear 903 follow the rotation, the primary transmission gear 903 transmits power to the secondary transmission gear 904 engaged therewith, so that the secondary transmission gear 904 and the rotating disc 905 rotate, the rotating disc 905 drives the rocker arm 1001 to reciprocate, thereby driving the plunger 1002 to reciprocate in the air cylinder 1101, and air is sucked into the air cylinder 1101 or air is extruded out of the air cylinder 1101 through the air pipe 1102, at this time, because of the engagement transmission of the linkage gear 603 and the follow-up gear 1203, the wind disc 1201 also rotates, when the air is extruded out of the air cylinder 1101, the air flows into the rotating wind disc 1201, the air is rotated and sprayed onto the motor 401, the driving gear 402 and the driven gear 302 through the air holes 1202, to assist in heat dissipation and control the temperature in the driving bin 2 to decrease.

[0032] See Figures 2-5 and Figure 7In the embodiment, a limiting assembly is installed in the driving bin 2, and a limiting sheet 803 is installed on the limiting assembly. The limiting assembly drives the limiting sheet 803 to be close to the linkage assembly and limits the linkage assembly. When the temperature sensor 5 detects that the temperature in the driving bin 2 reaches a threshold F1, the limiting sheet 803 is away from the linkage assembly. The limiting assembly includes a hanger 801 installed in the driving bin 2, a sliding rod 802 movably connected to the hanger 801, and a reset spring 804 connected to one end of the sliding rod 802. The limiting sheet 803 is fixedly installed on the sliding rod 802, and the limiting sheet 803 is matched with the limiting groove. The other end of the reset spring 804 is connected to the hanger 801, and the reset spring 804 is used to drive the limiting sheet 803 to be close to the docking disc 604. When the limiting sheet 803 enters the docking groove 605, the docking disc 604 stops rotating. When the docking head 703 enters the docking groove 605, the limiting sheet 803 leaves the docking groove 605, and the driving gear 402 drives the docking disc 604 to rotate. When the input end of the linkage assembly is not connected to the output end of the driving assembly through the docking assembly, the linkage assembly itself may rotate autonomously, and therefore the limiting assembly is needed to prevent the rotation of the linkage assembly when the linkage assembly is not running. After the docking head 703 is driven by the air cylinder 701 to leave the docking groove 605, the sliding rod 802 drives the limiting sheet 803 to enter the limiting groove under the action of the reset spring 804, so as to limit the rotation of the docking disc 604 (it is worth noting that the elastic force of the buffer spring 704 is greater than that of the reset spring 804). When the docking head 703 is inserted into the docking groove 605, the limiting sheet 803 is squeezed out of the docking groove 605 by overcoming the elastic force of the reset spring 804.

[0033] When working, the motor 401 outputs power to the driving gear 402, and through the meshing transmission action of the driving gear 402 and the driven gear 302, the fan blade 301 rotates at high speed to output wind power to accelerate the environmental air circulation.

[0034] When the motor 401 continuously runs, the motor 401 itself and the driving gear 402 and the driven gear 302 generate heat by friction, so that the temperature in the driving bin 2 rises. When the temperature sensor 5 detects that the temperature threshold reaches F1, a signal is sent to the air cylinder 701. The air cylinder 701 controls the docking seat 702 and the docking head 703 to move and be close to the docking disc 604, until the docking head 703 is inserted into the docking groove 605 and the limiting sheet 803 is pushed out of the docking groove 605 by overcoming the reset spring 804.

[0035] With the continuous rotation of the driving gear 402, the abutment 703 is abutted to one end of the abutment groove 605, the abutment 703 drives the abutment disc 604, the movable sleeve 601, the linkage bevel gear 602 and the linkage spur gear 603 to rotate, the linkage bevel gear 602 drives the transmission rod 901 and the primary transmission spur gear 903 to rotate through the meshing transmission with the transmission bevel gear 902, the primary transmission spur gear 903 further transmits power to the secondary transmission spur gear 904 meshed therewith, the secondary transmission spur gear 904 drives the rotating disc 905 to rotate, the rotating disc 905 further drives the rocker arm 1001 to swing back and forth, the rocker arm 1001 drives the plunger 1002 to move back and forth in the air cylinder 1101, and air is sucked into or squeezed out of the air cylinder 1101, at this time, the air disc 1201 also rotates due to the meshing transmission of the linkage spur gear 603 and the follower gear 1203;

[0036] When the air is squeezed out of the air cylinder 1101, the air flows into the air disc 1201 through the air pipe 1102, and with the rotation of the air disc 1201, the air is rotated and sprayed out of the air holes 1202 to the motor 401, the driving gear 402 and the driven gear 302, which assists in heat dissipation and controls the temperature drop in the control driving bin 2.
