Embodiment
Core of the present utility model is to provide a kind of motor of electric motor car, effectively improves the cooling effect of electric machine controller; Another core of the present utility model is to provide a kind of electric motor car comprising above-mentioned motor.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, the structural representation of the motor that Fig. 1 provides for embodiment a kind of in the utility model
In a kind of embodiment, motor provided by the utility model, this motor can be applied on electro-tricycle, also can be applied in other electric motor car, comprise fluid box 4, controller 3, air channel 1 and impeller 2, have liquid in fluid box 4, controller 3 is controller 3 common on the market, and the model of controller 3 can be determined according to the difference of concrete service condition.Controller 3 is installed on the top of liquid in fluid box 4, and position is higher than liquid level, and controller 3 can not for a long time in a liquid, and controller 3 gets rusty easily in a liquid and damages for a long time.The air outlet in air channel 1 is communicated with fluid box 4, and extraneous gas can enter fluid box 4, and the gas temperature entering fluid box 4 is lower than the gas temperature in fluid box 4, and the temperature of controller 3 is higher, and gas can cool to controller 3.Impeller 2 is installed in fluid box 4, and the flabellum of impeller 2 can be positioned at liquid, and the flabellum being that is arranged in below is positioned at liquid, and further restriction is not done in concrete flabellum position in a liquid, can determine according to actual service condition.The gas entering air channel 1 can drives impeller 2 operate, and the flabellum of drives impeller 2 rotates, and flabellum drives liquid to water on controller 3, cools to controller 3.The Packed box of controller 3 appearance tool, a small amount of liquid can not damage controller 3.The gas and the liquid that enter fluid box 4 all cool to controller 3, and cooling effect is better; Further, it is inner that gas and liquid go deep into fluid box 4, directly contacts with controller 3, and cooling effect more directly, more thoroughly, better.
Above-mentioned motor is only a kind of preferred version, is specifically not limited thereto, and can make pointed adjustment according to actual needs on this basis, thus obtain different execution modes.Impeller 2 extreme higher position is higher than the extreme higher position of controller 3, and flabellum rotates the liquid taken up in fluid box 4 and from top to bottom waters on controller 3.It should be noted that, the extreme higher position of impeller 2 mentioned here refers to the peak of the flabellum of impeller 2.The direction that flabellum rotates is different, and the direction that the liquid taken up in fluid box 4 waters on controller 3 is different.Impeller 2 extreme higher position is higher than the extreme higher position of controller 3, and liquid waters on controller 3 from top to bottom, and liquid runs through whole controller 3, and liquid and controller 3 direct contact surface amass comparatively large, more thorough to the cooling effect of controller 3.
On the basis of above-mentioned embodiment, those skilled in the art according to the difference of concrete occasion, can carry out some changes to motor.The direction that the import in air channel 1 is advanced along vehicle is offered, and the caliber in air channel 1 is diminished to air outlet gradually by its air inlet.When vehicle goes, the air inlet in air channel 1 is offered towards the direction of advance of vehicle, and blast is comparatively large, is conducive to gas and enters air channel 1.Gas is entered by the air inlet in air channel 1, formation wind is noted, the caliber in air channel 1 is diminished to air outlet gradually by its air inlet, certainly, diminishing gradually is one preferably execution mode, is not unique, also can be uneven diminishing, but easy forming station terrace, is not easy to gas flow during uneven change.Air channel 1 diminishes and can increase the pressure of wind, and the actuating force of the large drives impeller 2 of blast increases, and can improve the velocity of rotation of flabellum.
Obviously, under the guidance of this thought, those skilled in the art can carry out some changes according to the difference of concrete occasion to the air channel 1 in above-mentioned embodiment.The air outlet in air channel 1 just in time aims at impeller 2.The air outlet in air channel 1 aims at impeller 2, and the flabellum of gas-powered impeller 2 as much as possible is rotated, and improves the velocity of rotation of flabellum, the speed of accelerating liquid cooling controller 3.
It is important to note that motor provided by the utility model should not be restricted to this kind of situation.The liquid of fluid box 4 is specially liquid water, and fluid box 4 has inlet and liquid outlet, and liquid water enters from inlet always, flows out from liquid outlet.Liquid is specially liquid water, water wide material sources, pollution-free, be used widely, liquid water is cooling water, liquid water flows in fluid box 4, and liquid water circulates, and liquid water flows into from inlet, flow out from liquid outlet, liquid water constantly circulates, and makes the temperature of liquid keep lower, strengthens the effect of its cooling controller 3.
Based on the motor provided in above-described embodiment, the utility model additionally provides a kind of electric motor car, and this electric motor car comprises any one motor in above-described embodiment.The motor in above-described embodiment is have employed, so the beneficial effect of this electric motor car please refer to above-described embodiment due to this electric motor car.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
