Technical Field

[0001] The utility model belongs to the technical field of electric vehicles, and more specifically relates to an R290 environmentally friendly refrigerant electric vehicle motor cooling device. Background Art

[0002] Most of the existing electric vehicle drive motors are permanent magnet motors. Once the permanent magnet motor reaches high temperature, the stator will demagnetize, causing the permanent magnet motor to be scrapped. Therefore, the motor cooling system is very important. The air conditioning system, water tank, water pump, cooling fan, etc. that use R290 environmentally friendly refrigerant are all important equipment that constitute the motor cooling system. They can directly or indirectly affect the temperature of the electric vehicle drive motor.

[0003] The utility model, currently filed with application number CN201520229215.0, provides an automotive electronic water pump comprising a rear cover, a drive circuit board, a stator, a motor housing, a rotor, a motor shaft, and a water pump housing. The rear cover is connected to a socket on the drive circuit board, which is connected to the stator. The stator is fixed within the motor housing. The rotor is mounted on the motor shaft and positioned within the motor housing. One end of the motor shaft is rotatably connected to the motor housing, and the other end extends into the water pump housing. The water pump housing is fixedly connected to the motor housing, which is connected to the rear cover. The automotive electronic water pump also includes an internal support frame for the water pump housing, which covers the end of the motor shaft within the water pump housing. The internal support frame is integrally formed with the water pump housing. The automotive electronic water pump provided by the utility model utilizes a support structure that extends the end of the motor shaft into the internal support frame of the water pump housing, enabling long-term operation. Furthermore, the system prevents the water pump impeller rotor from swinging and interfering with the water flow direction, thereby ensuring the service life of the water pump and improving the efficiency of the cooling system.

[0004] Based on the above, the electronic water pump is an indispensable key component in the cooling system of electric vehicle motors. Its installation usually relies on a mounting bracket and multiple sets of bolts to fix it inside the vehicle cabin. During installation, the operator must first tighten the multiple sets of bolts one by one, and then return one by one for the final tightening operation. This installation process is particularly cumbersome and time-consuming. Utility Model Content

[0059] Insert 702, two inserts 702 are provided, and the two inserts 702 are fixedly connected to the outside of the two sliding plates 7 respectively. The function brought about is that by pressing the two pressing members 701 inward, the two sliding plates 7 can be driven to slide inward at the same time, thereby driving the two pressing members 701 to retract into the interior of the second connecting member 6.

[0060] The separate installation components also include:

[0061] The return spring 703, the front and rear ends of the return spring 703 are respectively fixedly connected to the inner sides of the two sliding plates 7, which has the effect of loosening the two pressing parts 701.
