The specific embodiment.
In conjunction with the accompanying drawings and embodiments the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As the lifting drive of Fig. 1 Fig. 2 a kind of electric pushrod shown in Figure 3, form by support shell 1, motor 2, motor down-lead 3, shock absorbing ring 4, motor retainer 5, left damping cushion block 6, right damping cushion block 7, back damping pad piece 8 and cover plate 9.
The permanent magnet direct current motor that motor 2 slows down for band, its shell is oblate, motor retainer 5 has the hole that matches with motor 2 shell shapes, be sleeved on motor 2 shells, motor retainer 5 both sides have the aliform wing 51 that stretches out respectively, on left side damping cushion block 6 and the right damping cushion block 7 inner arc that matches with motor retainer 5 outer arcs is arranged, and the centre is respectively arranged with left slot 61 and right slot 71, when left damping cushion block 6 and right damping cushion block 7 are respectively installed to motor retainer 5 both sides, the aliform wing 51 of motor retainer 5 both sides inserts respectively in left slot 61 and the right slot 71, makes motor 2, motor retainer 5, left side damping cushion block 6 and right damping cushion block 7 can not produce relative rotation; On back damping pad piece 8, be provided with the pit that matches with motor 2 shell ends, motor 2 shells end embedded in the back damping pad piece 8 by this pit.After all damping cushion blocks were installed motor 2, its formed outer shape and support shell 1 matched, and can directly touch and put into support shell 1; Motor 2 is packed into behind the support shell 1, its spindle centerline becomes an oblique angle with support shell 1 limit, two drift slots about motor 2 both sides have formed, correspondingly, left side damping cushion block 6 and right damping cushion block 7 also are designed to wedge shape respectively, be in respectively in these two drift slots, for preventing that left damping cushion block 6 and right damping cushion block 7 from sliding toward the big extreme direction of skewed slot, two retaining sheets 91 about having designed respectively on the cover plate 9, when cover plate 9 covers on the support shell 1, retaining sheet 91 on the cover plate 9 withstands a left side respectively, right damping cushion block 6,7 big end makes a left side, right damping cushion block 6,7 can not slide; For preventing that motor 2 and cover plate 9 from coming in contact, between motor 2 front portions and cover plate 9, be placed with shock absorbing ring 4, left side damping cushion block 6, right damping cushion block 7, back damping pad piece 8 and shock absorbing ring 4 are made by rubber, foamed plastics or foam sponge class material, when cover plate 9 covers on chassis block 1, left side damping cushion block 6, right damping cushion block 7, back damping pad piece 8 and shock absorbing ring 4 are suitably pushed, thereby motor 2 is fixed in the chassis block 1.Support by left damping cushion block 6, right damping cushion block 7, back damping pad piece 8 and shock absorbing ring 4, motor 2 is suspended and is installed in flexibly in the chassis block 1, when motor 2 work, the vibrations of its generation and noise major part are by left and right and back damping pad piece 6,7,8 and shock absorbing ring 4 absorptions, thereby play the effect of damping noise reduction, pass through for ease of motor down-lead 3 simultaneously, on left damping cushion block 6 or right damping cushion block 7, crossed beam trunking 62 or hole can be set, in the present embodiment, being provided with on left damping cushion block 6 can be by the crossed beam trunking 62 of motor down-lead 3.
For not influencing the heat radiation of motor 2, left side damping cushion block 6, right damping cushion block 7, back damping pad piece 8 are designed to separately independently part, and reserving enough big distance each other, avoid that motor 2 is formed large tracts of land and surround, so that motor 2 shells are exposed as much as possible, to guarantee not influence motor 2 heat radiations, simultaneously, 5 also have slotted eye 52 on the motor retainer, to increase the area of dissipation of motor 2, improve the radiating effect of motor 2.
