Abstract
The utility model discloses an end cover of a motor, which comprises an end cover body (1), wherein a bearing base (2) is arranged in the middle part of the end cover body (1); a plurality of heat dissipation lug bosses (11) are arranged on the inner bottom surface of the end cover body (1) outside the bearing base (2); the plurality of heat dissipation lug bosses (11) are spaced with each other; and a heat dissipation channel (3) is formed around each heat dissipation lug boss (11). The end cover of the motor disclosed by the utility model has the advantages of being simple in structure, large in heat dissipation area, rapid for heat dissipation, good in heat dissipation effect, material-saving and low in cost.
Description
Technical field:
The utility model relates to a kind of electric motor end cap.
Background technology:
The quality of motor radiating effect directly affects motor performance, and for present powerful aluminium envelope motor, particularly be applied to the motor of New-energy electric vehicle, the motor seal class requirement is higher, electric machine temperature rise is high, the outside can solve by fan cooling, but inner winding radiating effect is undesirable, only do not satisfy requirement by stator core with the heat radiation that contacts of aluminium lid, usually adopt in end cap inside bottom surface increase bar shaped radiating ribs and dispel the heat to winding, but the bar shaped radiating ribs, radiating efficiency is low, and waste of material is larger, causes high expensive.
Summary of the invention:
The purpose of this utility model is for the technological deficiency that exists in the prior art, and a kind of electric motor end cap is provided, and this is simple in structure, increasing heat radiation area, and rapid heat dissipation, good heat dissipation effect, and save material, reduce cost.
The purpose of this utility model is to be achieved by following technical scheme.
A kind of electric motor end cap comprises the end cap body, and the middle part of end cap body arranges bearing pedestal, and outside bearing pedestal, end cap body inside bottom surface is provided with some heat radiation boss, some heat radiation boss space forms heat dissipation channel around each heat radiation boss.
Some heat radiation boss described above are distributed on many straight lines.
Many straight lines described above were the radial alignment at center.
Heat radiation boss on many straight lines described above is equally distributed.
Heat radiation boss described above is cylinder or tetragonal body.
Heat radiation boss described above and end cap body are the one cast aluminium formings.
End cap body outer side surface described above protrudes mounting bracket.
Establish wire hole on the bottom surface of end cap body described above.
The beneficial effects of the utility model are: 1) the utility model end cap body inside bottom surface is provided with some heat radiation boss, some heat radiation boss space, form heat dissipation channel around each heat radiation boss, the heat that stator winding gives out is delivered on the heat radiation boss and by the heat radiation boss and dispels the heat, and is simple in structure, increasing heat radiation area, the winding rapid heat dissipation, good heat dissipation effect, and save material, reduce cost; 2) the heat radiation boss is cylinder or tetragonal body, compares with traditional bar shaped radiating ribs, and the heat radiation girth that the heat radiation boss forms is the same with straight shape radiating ribs area, and radiating effect is the same, but can save material over half, reduces production costs; 3) heat radiation boss and end cap body are the one cast aluminium formings, and applicable batch production is made.
Description of drawings:
Fig. 1 is the stereogram of the utility model end cap.
Fig. 2 is the structural representation of the utility model end cap.
Embodiment:
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment one: as depicted in figs. 1 and 2, the utility model is a kind of electric motor end cap, comprise end cap body 1, the middle part of end cap body 1 arranges bearing pedestal 2, outside bearing pedestal 2, end cap body 1 inside bottom surface is provided with some heat radiation boss 11, some heat radiation boss 11 spaces form heat dissipation channel 3 around each heat radiation boss 11.
Embodiment two: the basis at embodiment one increases following technical characterictic: some heat radiation boss 11 are distributed on many straight lines 4.
Embodiment three: the basis at embodiment two increases following technical characterictic: many straight lines 4 were the radial alignment at center.
Embodiment four: increase following technical characterictic on the basis of embodiment two or embodiment three: the heat radiation boss 11 on many straight lines 4 is equally distributed.
Embodiment five: the basis at embodiment one or embodiment two or embodiment three increases following technical characterictic: heat radiation boss 11 is cylinder or tetragonal body.
Embodiment six: the basis at embodiment one or embodiment two or embodiment three increases following technical characterictic: heat radiation boss 11 and end cap body 1 are the one cast aluminium formings.
Embodiment seven: the basis at embodiment one increases following technical characterictic: end cap body 1 outer side surface protrudes mounting bracket 12.
Embodiment eight: the basis at embodiment one increases following technical characterictic: wire hole 13 is established in the bottom surface of end cap body 1.
Because the application is mechanical field, the apparent association of ability those of ordinary skill obtains: the technical characterictic independent assortment of the increase that embodiment two, embodiment three, embodiment four, embodiment five, embodiment six, embodiment seven and embodiment eight mention is combined into new technical scheme with the technical scheme of embodiment one.
The utility model end cap body 1 inside bottom surface is provided with some heat radiation boss 11, some heat radiation boss 11 spaces, form heat dissipation channel 3 around each heat radiation boss 11, some heat radiation boss 11 are distributed on many straight lines 4, the boss 11 that perhaps dispels the heat distributes ringwise or curved line distributes, be not limited to the lineal layout mode, the heat that stator winding gives out is delivered on the heat radiation boss 11 and by heat radiation boss 11 and dispels the heat, simple in structure, increasing heat radiation area, rapid heat dissipation, good heat dissipation effect, and the saving material reduces cost.
