[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1, Figure 2 and Figure 3 As shown, a thermal balance control device for an electric vehicle motor includes a box body 1, a heat dissipation component 2 is fixedly installed on the left side of the box body 1, a motor 5 is fixedly installed on the bottom of the inner wall of the box body 1, a thermal balance adjustment component 3 is fixedly installed on the top right side of the box body 1, and an interception component 4 is fixedly installed on the middle part of the upper end of the box body 1.

[0027] The heat generated by the motor 5 during operation can be absorbed and cooled by the heat dissipation component 2, thereby reducing the energy consumption of the motor 5. The heat balance adjustment component 3 can drive the rotation of the heat dissipation blades 37 while expanding the heat absorption range of the suction heads 24. The heat dissipation blades 37 accelerate the air flow inside the box 1, so that the heat emitted by the motor 5 can be blown up evenly, thereby improving the uniformity of the overall temperature control of the motor 5. The interception component 4 can filter the outside air when the air flows inside and outside the box 1 to prevent dust from entering the box 1. In addition, after the filter plate 44 has been working for a period of time, its replacement, cleaning and installation are relatively simple, thereby improving the overall maintainability of the device.

[0028] like Figure 4 As shown, the heat dissipation assembly 2 includes a condenser 21, the right side of the condenser 21 is fixedly installed on the left bottom of the box body 1, a connecting pipe is fixedly installed on the input end of the condenser 21, a fan 22 is fixedly installed on the left top of the box body 1, and the end of the connecting pipe away from the condenser 21 is fixedly installed on the output end of the fan 22, the input end of the fan 22 is rotatably connected to a heat absorption pipe 23 that passes through the left part of the box body 1, the right end of the heat absorption pipe 23 passes through the right part of the box body 1, and a plurality of linearly arranged air suction heads 24 are fixedly installed on the bottom of the outer wall of the heat absorption pipe 23.

[0029] The fan 22 can extract the hot air in the box 1 through a plurality of suction heads 24. The hot air enters the condenser 21 through the heat absorption pipe 23 and the connecting pipe. The condenser 21 cools the hot air to liquid and discharges it to the outside. The condenser 21 and the fan 22 are both existing structures and will not be elaborated here.

[0030] like Figure 4 As shown, the thermal balance adjustment component 3 includes an electric push rod 31, the outer wall of the electric push rod 31 is fixedly installed at the top position of the right front part of the box body 1, the output end of the electric push rod 31 is fixedly installed with a rack 32, and the rear end of the rack 32 is fixedly installed with a slide rod 33.

[0031] The rack 32 is moved by the movement of the output end of the electric push rod 31 . When the rack 32 moves, the slide bar 33 slides at a corresponding position. The setting of the slide bar 33 has a limiting effect on the movement of the rack 32 .

[0032] like Figure 4As shown, the outer wall of the slide rod 33 is slidably connected to the inner wall at the top position of the right rear part of the box body 1, and a gear 34 is fixedly sleeved on the right part of the outer wall of the heat absorption tube 23, and the outer surface of the gear 34 is meshed with the upper end of the rack 32.

[0033] The gear 1 34 drives the heat absorption tube 23 to rotate a certain angle by meshing with the rack 32, so that the plurality of suction heads 24 can expand the extraction range of hot air.

[0034] like Figure 4 As shown, the front and rear positions of the top right side of the box body 1 are rotatably connected with a rotating shaft 35 that passes through the right part of the box body 1, and the right parts of the outer walls of the two rotating shafts 35 are fixedly sleeved with gear 2 36, and the outer surfaces of the two gear 2 36 are meshed with the outer surface of gear 1 34, and the left parts of the outer walls of the two rotating shafts 35 are fixedly installed with a plurality of heat dissipation fan blades 37 arranged in a ring form.

[0035] The two gears 2 36 are meshed with the gear 1 34 to simultaneously drive the plurality of heat dissipation blades 37 to rotate. The plurality of heat dissipation blades 37 make the air flow inside the box 1 faster, so that the hot air at the bottom of the inner cavity of the box 1 is blown up, thereby preventing the phenomenon of local over-temperature when the motor 5 is running.

[0036] like Figure 5 and Figure 6 As shown, the interception component 4 includes a mounting frame 41, a rectangular through slot is provided in the middle of the upper end of the box body 1, the lower end of the mounting frame 41 is fixedly installed with the upper end of the box body 1, the mounting frame 41 is located above the rectangular through slot, and the front and rear parts of the inner wall of the mounting frame 41 are provided with slide slots 42, and the opposite sides of the inner walls of the two slide slots 42 are slidably connected with sliders 43, and the opposite ends of the two sliders 43 are fixedly installed with filter plates 44.

[0037] The filter plate 44 is mainly made of polypropylene and has a high filtering accuracy. The filter plate 44 can be positioned at a specified position by sliding two sliders 43 in two slide grooves 42. The bottom of the inner wall of the two slide grooves 42 is flush with the upper ends of the two support plates 45 at the bottom.

[0038] like Figure 6 As shown, the upper and lower parts of the left and right sides of the installation frame 41 are slidably connected with support plates 45 that penetrate the left and right parts of the installation frame 41, the opposite sides of four upper and lower adjacent support plates 45 overlap with the left and right parts of the upper and lower sides of the filter plate 44, the front and rear parts of the four left and right adjacent support plates 45 away from each other are fixedly installed with adjustment rods 46, and the four left and right adjacent adjustment rods 46 away from each other are fixedly installed with connecting plates 47.

[0039] The corresponding adjusting rods 46 and the supporting plates 45 can be pulled apart by the two connecting plates 47, so that the filter plates 44 on the opposite sides of the four adjacent supporting plates 45 can be released from the restricted state, so that the filter plates 44 can be quickly replaced or cleaned after being used for a period of time.

[0040] like Figure 6 As shown, the outer walls of four left and right adjacent adjustment rods 46 are movably sleeved on one side away from each other with a spring 48, the opposite ends of the four left and right adjacent springs 48 are fixedly connected to the side away from each other of four left and right adjacent support plates 45, and the side away from each other of the four left and right adjacent springs 48 are fixedly connected to the upper and lower parts of the opposite sides of the two connecting plates 47.

[0041] In the process of applying force to the two connecting plates 47, the corresponding spring 48 will be affected by the force and accumulate spring potential energy. After the two connecting plates 47 lose the force, the corresponding spring 48 will instantly release the elastic potential energy and drive the corresponding adjusting rod 46 and the support plate 45 to reset. The setting of the spring 48 facilitates the operator to quickly complete the installation and disassembly of the filter plate 44.

[0042] The working principle of the utility model is as follows: during the continuous operation of the motor 5, a certain amount of heat will be generated inside the box 1. A temperature sensor is generally provided inside the box 1. After reaching a certain temperature, the condenser 21, the fan 22 and the electric push rod 31 are automatically started. The fan 22 extracts the hot air inside the box 1 through a plurality of suction heads 24. The hot air enters the connecting pipe from the heat absorption pipe 23, and then enters the condenser 21 from the connecting pipe. The condenser 21 cools the hot air and releases it.

[0043] At the same time, the back and forth telescopic action of the output end of the electric push rod 31 drives the rack 32 to move, and the gear 1 34 drives the heat absorption tube 23 to rotate by meshing with the rack 32. The rotation of the heat absorption tube 23 enables the several suction heads 24 to expand the suction range of the hot air inside the box 1. At this time, the two gears 2 36 drive the several heat dissipation blades 37 to rotate by meshing with the gear 1 34, and the several heat dissipation blades 37 accelerate the air flow inside the box 1.

[0044] The hot air is extracted, and new air enters the box body 1 through the rectangular slot. The filter plate 44 filters and intercepts tiny particles in the air. After the filter plate 44 has worked for a period of time, the operator can pull the two connecting plates 47 at the same time. The two connecting plates 47 drive the four adjacent adjusting rods 46 on the left and right to move away from each other. At this time, the four springs 48 are subjected to tensile force, and the four adjusting rods 46 drive the corresponding supporting plates 45 to slide away from the mounting frame 41. The operator takes out the filter plate 44 for processing.

[0045] When installing the filter plate 44, pull the connecting plate 47 to a suitable position, then move the filter plate 44 to a fixed position by sliding the two sliders 43 in the two slide grooves 42. After loosening the connecting plate 47, the elastic restoring force of the four springs 48 drives the four support plates 45 to reset, and the four support plates 45 limit the filter plate 44, thereby preventing the filter plate 44 from shaking unsteadily when the electric vehicle moves.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
