Description
Technical field
This utility model relates to scooter, particularly to a kind of scooter and wheel hub motor thereof.
Background technology
Scooter is the novel product form of another skateboarding after conventional skateboard.Existing scooter is the most all accompanied with battery and wheel hub motor, rides instead of walk to facilitate.For being easy to carry of scooter, the structure entirety of scooter requires the compactest, thus the structure of wheel hub motor also design the compactest.But motor can generate heat in the course of the work, the compactest meeting of hub motor structure is unfavorable for the heat radiation of motor, can reduce electric efficiency in the process of moving, be unfavorable for the flying power of scooter.
At present, the Chinese patent of Publication No. CN 204205801 U discloses the heat-dissipating casing of a kind of Segway Human Transporter wheel hub motor, it includes motor main casing, wheel hub and case lid, described motor main casing is in the form of annular discs, it is evenly arranged dowel by several in its exterior side wall to be connected with the medial wall of ring-type wheel hub, being provided with case lid on one side end face of described motor main casing, the excircle sidewall upper shaft of described motor main casing and case lid is to being evenly arranged radiating groove.Although the heat-dissipating casing surface area of this Segway Human Transporter wheel hub motor is easy to more greatly heat radiation, but the axially arranged meeting of radiating groove is greatly increased the volume of wheel hub motor, is unfavorable for carrying.
Utility model content
The deficiency existed for prior art, first purpose of the present utility model is to provide a kind of scooter and wheel hub motor thereof, can promote the heat-sinking capability of wheel hub motor in the case of wheel hub motor volume is not significantly increased.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of scooter hub motor, including housing, enclosure interior is provided with the cavity for placing motor, housing exterior walls is arranged with rubber wheel, housing two ends are provided with for enclosure cavity the end cap that clamps rubber wheel, described end cap is provided with the Y shape heat sink strip protruding end cap, and heat sink strip and end cap are wholely set and are uniformly distributed along the circumference, and end cap is divided into several hexagonal space by heat sink strip.
Pass through technique scheme, end cap is provided with the heat sink strip protruding end cap, the area of dissipation that wheel hub motor is overall can be increased, heat sink strip and end cap are wholely set simultaneously, the conduction of heat being easy between end cap and heat sink strip, when the heat that motor produces is delivered on end cap, heat also can be rapidly transferred on heat sink strip, increases area of dissipation.Heat sink strip is uniformly distributed along the circumference, and the heat being possible to prevent on heat sink strip accumulates at end cap one, it is simple to accelerate radiating rate.End cap is divided into several hexagonal space by heat sink strip, the most hexagonal alveolate texture has bigger surface area, it is simple to heat radiation, and alveolate texture has preferable structural strength simultaneously, ending cover thickness can be reduced, to facilitate the radiating rate being in the motor within end cap and housing.
Preferably, the heat dissipation channel along the distribution of heat sink strip length direction it is provided with in the middle part of described heat sink strip.
By technique scheme, when this wheel hub motor rotates, extraneous air-flow can enter in heat dissipation channel, on the one hand increases the area of dissipation that wheel hub is overall, and on the other hand the point of the speed air flow in heat dissipation channel is very fast, it is simple to improve radiating rate.
Preferably, the lateral cross section of described heat dissipation channel is U-shaped.
By technique scheme, heat sink strip still has preferable structural strength after offering heat dissipation channel.Simultaneously when heat sink strip is by impact force action, can deform in heat dissipation channel, deformation for heat sink strip provides deformation space, prevent heat sink strip from not having deformation space to cause heat sink strip to ftracture in this place owing to the deflection of certain is relatively big, affecting the overall structural strength of heat sink strip, opposite end is built less than preferable supporting role.
Preferably, described heat dissipation channel width is the 35% ~ 45% of heat sink strip width.
Through mass data analysis, when heat dissipation channel width in this range time, the intensity of heat-sinking capability and heat sink strip can be taken into account, on the premise of proof strength, as much as possible improve the heat-sinking capability of radiating groove.
Preferably, described heat sink strip both sides are by being attached between inclined-plane and end cap.
Pass through technique scheme, there is between heat sink strip and end cap preferable bonding strength, inclined-plane is more not easy dust stratification laying dust relative to vertical face simultaneously, at this wheel hub motor when rotating, the dust etc. being attached to heat sink strip side can be thrown out of, it is to avoid due to the radiating rate of the phenomena impair heat sink strip such as dust stratification, laying dust.End cap so arranges the processing that can also be easy to end cap simultaneously, convenient during the end cap demoulding.
Preferably, described housing and end cap are made by aluminium alloy.
By technique scheme, housing and end cap, there is the preferable capacity of heat transmission, promptly the heat that motor produces can be exported to end cap in internal cavities and surface of shell dispels the heat.Aluminium alloy has stronger intensity simultaneously, identical requirement of strength lower wall thickness can do relatively thin, to increase heat-sinking capability further.
Preferably, described end cap includes that left end cap and right end cap, left end cap and housing are wholely set, and right end cap is fixed by screws on housing.
Can be easy to process with integrated die-casting molding by technique scheme, housing and left end cap, there is preferable bonding strength simultaneously.Right end cap is connected by screw and housing, easy accessibility, it is simple to the motor of enclosure interior is installed.
Preferably, described motor includes motor shaft, and motor shaft stretches out housing from right end cap, and motor shaft stretches out the middle part of right end cap section and is milled with plane, forms anti-delinking part between plane and motor shaft ends.
Pass through technique scheme, wheel hub motor can be fixed more conveniently, prevent wheel hub motor from loosening, simultaneously, plane on motor shaft is positioned at motor shaft and stretches out the middle part of right end cap, having no through the end face of the motor shaft section of stretching out, its front end forms an anti-delinking part, can effectively prevent the possibility that wheel hub motor comes off from vehicle frame.
In sum, this utility model in contrast to the heat sink strip having the beneficial effect that by arranging Y shape on end cap of prior art, can must improve the area of dissipation on end cap by a relatively large margin, increases radiating rate.Meanwhile, heat sink strip the intensity that can preferably increase end cap is set.Being provided with the heat dissipation channel along heat sink strip length direction in heat sink strip, when wheel hub motor rotates, the wind taken up can enter in heat dissipation channel, further speeds up the radiating rate of heat sink strip simultaneously.Heat sink strip both sides are connected with end cap by inclined-plane, on the one hand increase the intensity of heat sink strip, and on the other hand the junction of heat sink strip and end cap can be avoided to accumulate water or mud etc. affects the heat dispersion of end cap.
Second purpose of the present utility model is to provide a kind of preferable scooter of flying power.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of scooter, including above-mentioned wheel hub motor.
By technique scheme, the wheel hub motor heat-sinking capability of this scooter is preferable, is conducive to its internal motor radiating, improves the efficiency of motor, thus improve the overall flying power of this slide plate side.
