Description

Technical Field

[0001] The utility model relates to the technical field of automobile motors, in particular to an automobile motor with active strong heat dissipation. Background Art

[0002] The motor is an important electrical appliance in a car. With the development of automobile automation and intelligence, the use of motors is increasing as the manual operation of functions is replaced by the automation of motors.

[0003] Minor problems with car use are issues that customers are very concerned about and are also issues that car manufacturers need to pay attention to. Take the motor as an example. The reliability of the car motor is an important assessment indicator. Although motor technology is very mature, the reliability of motors of different models or produced by different manufacturers is also different.

[0004] A key issue in ensuring long-term stable operation of automotive motors is heat dissipation. If heat dissipation is inadequate, the rotor coils will overheat over time, accelerating wire aging and leading to a host of other problems. Existing automotive motors only have a fan at the rear to draw air from the outside toward the heat sink, dissipating heat from the motor casing. However, heat is primarily generated within the rotor, making this external cooling method very limited and unable to meet the high-intensity demands of today's automotive motors, presenting a significant drawback. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an active strong heat dissipation automobile motor, which is used to solve the problem that the existing automobile motor only has a fan at the rear to dissipate heat from the outside of the shell, resulting in a relatively limited heat dissipation effect.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An active, highly heat-dissipating automotive motor comprises a front cover, a rear cover, a housing, a stator, a rotor, and a rotating shaft. The rotor is fixed to the surface of the rotating shaft. The stator is movably sleeved on the surface of the rotor and fixedly mounted on the inner wall of the housing. The front cover and the rear cover are fixedly mounted at both ends of the housing. A heat dissipation plate is axially provided on the housing. The rotating shaft is rotatably connected to the front cover and the rear cover via a bearing.

[0008] A retaining ring is fixedly connected to the side of the rear end cover facing away from the rotor, a through hole is provided on the rear end cover and is located inside the retaining ring, a centrifugal fan blade is fixedly sleeved and mounted on the rotating shaft on one side of the retaining ring, and a wind shield is fixedly mounted on the rear end cover and is located outside the retaining ring and the centrifugal fan blade;

[0009] The front end cover is fixedly connected to a guide plate movably sleeved on the surface of the rotating shaft on one side of the corresponding rotor. The front end cover is provided with a through groove located on the outside of the guide plate. The surface of the rotating shaft between the guide plate and the rotor is fixedly sleeved with an induced draft fan blade.

[0010] Preferably, the heat sink and the housing are an integral structure, and the cross section of the heat sink is T-shaped.

[0011] Preferably, the diameter of the retaining ring is not greater than the diameter of the centrifugal blade, and the diameter of the centrifugal blade is not less than the diameter of the rotor.

[0012] Preferably, the through holes are equidistantly arranged along the circumferential direction on the rear end cover, the through holes are oblique holes, and the distance between one end of the retaining ring corresponding to the through hole and the rotating shaft is smaller than the distance between one end of the rotor corresponding to the through hole and the rotating shaft.

[0013] Preferably, the guide plate is a conical plate with a protrusion on one side corresponding to the induced draft fan blade.

[0014] Preferably, the centrifugal fan blades and the induced draft fan blades are both metal blades.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model provides a through hole on the rear end cover, a through slot on the front end cover, and ventilated fan blades in the front end cover and the shell. The rotation of the rotating shaft simultaneously drives the centrifugal fan blades and the ventilated fan blades to rotate at high speed, so as to achieve the purpose of synchronous blowing air and heat dissipation inside and outside the shell, and solves the problem of the limited heat dissipation effect of the existing automobile motor which only provides a fan at the rear end to dissipate heat from the shell from the outside.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-7 As shown, the utility model provides a technical solution: an active strong heat dissipation automobile motor, comprising a front cover 1, a rear cover 2, a housing 3, a stator 4, a rotor 5 and a rotating shaft 6, wherein the rotor 5 is fixed to the surface of the rotating shaft 6, the stator 4 is movably sleeved on the surface of the rotor 5 and fixedly mounted on the inner wall of the housing 3, the front cover 1 and the rear cover 2 are fixedly mounted at both ends of the housing 3, a heat dissipation plate 7 is axially arranged on the housing 3, the heat dissipation plate 7 and the housing 3 are an integral structure, and the cross section of the heat dissipation plate 7 is T-shaped, and the rotating shaft 6 is rotatably connected to the front cover 1 and the rear cover 2 through a bearing 8;

[0027] A retaining ring 9 is fixedly connected to the side of the rear end cover 2 facing away from the rotor 5. The diameter of the retaining ring 9 is not larger than the diameter of the centrifugal blade 11. A through hole 10 is provided on the rear end cover 2, which is located inside the retaining ring 9. The through holes 10 are equidistantly arranged along the circumferential direction on the rear end cover 2. The through holes 10 are oblique holes, and the distance between one end of the through hole 10 corresponding to the retaining ring 9 and the rotating shaft 6 is smaller than the distance between one end of the through hole 10 corresponding to the rotor 5 and the rotating shaft 6. A centrifugal blade 11 is fixedly sleeved and mounted on the rotating shaft 6 on one side of the retaining ring 9. The diameter of the centrifugal blade 11 is not smaller than the diameter of the rotor 5. A wind shield 12 is fixedly mounted on the rear end cover 2, which is located outside the retaining ring 9 and the centrifugal blade 11.

[0028] The front end cover 1 is fixedly connected to the side of the rotor 5 corresponding to the guide plate 13, which is movably sleeved on the surface of the rotating shaft 6. The guide plate 13 is a conical plate raised on the side corresponding to the induced fan blades 15. The front end cover 1 is provided with a through groove 14 located on the outside of the guide plate 13. The induced fan blades 15 are fixedly sleeved on the surface of the rotating shaft 6 between the guide plate 13 and the rotor 5. The centrifugal fan blades 11 and the induced fan blades 15 are both metal fan blades, usually made of cast aluminum, which helps to dissipate heat.

[0029] Working principle:

[0030] By arranging through holes 10 and retaining rings 9 on the rear end cover 2, arranging through slots 14 on the front end cover 1, and arranging induced fan blades 15 in the front end cover 1 and the housing 3, the rotation of the rotating shaft 6 simultaneously drives the centrifugal fan blades 11 and the induced fan blades 15 to rotate at high speed, and the centrifugal fan blades 11 squeeze the air to the surroundings and flow it out from the front end of the wind cover 12, and blow it toward the housing 3 along the T-shaped heat sink 7. The T-shaped heat sink 7 has a better diversion effect, which contributes to the overall heat dissipation of the housing 3; in addition, the air flow may be mixed with dust, and the centrifugal fan blades 11 use centrifugal force to push the dust away from the rotating shaft 6, and the retaining ring 9 has the effect of isolating dust. A part of the air enters the interior of the housing 3 from the through holes 10 under the action of the induced fan blades 15, and flows out from the through slots 14, directly blowing air to the rotor 5 and the stator 4 inside the housing 3 for heat dissipation, thereby achieving the purpose of synchronous heat dissipation inside and outside the housing 3, and having a better heat dissipation effect.
