In containment housing 75, also temperature sensor is installed, when temperature is lower or higher in containment housing 75, servomotor 81 can be started and/or regulate motor 31 pairs of air outputs to regulate; When starting servomotor 81, inner sleeve 80 is driven to rotate, because inner sleeve 80 length is highly suitable with containment housing 75, the reinforcement 88 that inner sleeve 80 inwall is arranged can strengthen the moment of torsion of inner sleeve 80, inner sleeve 80 rotates, adjustable arc hole 85 and the size overlapped between outer arcuate hole 84, thus the size regulating air output; When starting adjustment motor 31, flexible hose 97 clamps by rear clamp ring 46 and front clamp ring 47, carries out air output adjustment by the distance between rear clamp ring 46 and front clamp ring 47.Concrete adjustment process is as follows: regulate motor 31 by manipulation, motor 31 driven wheel 33 is regulated to rotate, gear 33 drives the tooth bar 34 that is engaged with along square tube 32 or be moved to the left to the right, the pull bar 36 coaxial with tooth bar 34 promotes or pulls travelling carriage 37 to move up or down, under the effect of extension spring 48, rear slider 42 on rear plate 38 and the front-slider 43 on front plate 39 slide along rear rail 40 and fromer rail 41 all the time respectively, when pull bar 36 upwards pushes away, travelling carriage 37 moves up, distance between rear rail 40 and fromer rail 41 increases, under the effect of lever principle, the rear clamp ring 46 of rear plate 38 upper end and the front clamp ring 47 of front plate 39 upper end grip flexible hose 97, the sectional area of flexible hose 97 diminishes, air output reduces, in like manner, when pull bar 36 pulls down, the sectional area of flexible hose 97 becomes large, air output increases, so just can regulate the air output in containment housing 75, thus reach the effect regulating good heat radiating in containment housing 75.

In rotational sealing structure 28, the sealing shroud 52 of polyurethane material, not only has good sealing function, and smooth, wearing quality good; Upper limit ring 50 and lower limit ring 49, for limiting the position of sealing shroud 52, when sealing shroud 52 changed by needs, can be backed out trip bolt 51, be taken off by lower limit ring 49 and sealing shroud 52 can be taken out and install new sealing shroud 52.

Inner sleeve 80 lower end to be plugged in erection column 83 and to contact with shaft coupling 82, be fixedly connected with by the mounting screw 74 along horizontal radial direction between inner sleeve 80 with erection column 83, so not only support the gravity of inner sleeve 80 itself, and can be inner sleeve 80 driving torque is provided.

Sliding sleeve 87 plays the effect limiting inner sleeve 80 and do not tilt, when changing after wearing and tearing, and the effect that locating ring 86 does not move down for limiting sliding sleeve 87.

In addition, supported by manipulation and regulate oil cylinder 91, base and portable plate 93 can be driven upwards to rotate with the center of bearing pin 94, the traveling characteristics of self-balancing type electric unicycle upward slope or descending can be tested like this.The size of the gradient reaches by the corresponding matching of pointer 96 with angle dial 95, operates convenient.

The present embodiment not does any pro forma restriction to shape of the present utility model, material, structure etc.; every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all belong to the protection domain of technical solutions of the utility model.
