This involution assembly 4 convexes with two butting sections 41.

The assembling process of seat lifting actuator described in the utility model is as follows: earlier involution assembly 4 is sheathed between pedestal 21 and the permanent seat 31, and the joint pin 212 that makes pedestal 21 is connected to the connecting bore 312 of permanent seat 31, allow pedestal 21 and permanent seat 31 form the location, assemble transmission group 3 again, fluted disc 32 is packed in the permanent seat 31, allow the 3rd tooth bar 323 of fluted disc 32 outer rims be engaged in first tooth bar 311, then eccentric shaft 33 is penetrated fluted disc 32, articulated section 333 is fixed in the axis hole 322 of fluted disc 32, and allow pivot 331 pass permanent seat 31 and pedestal 121, and pass by pedestal 21, again drive plate 34 is covered on permanent seat 31 surfaces, make 321 driving holes 342 that are positioned at drive plate 34 that take off post of fluted disc 32, then right cap 12 is covered on drive plate 34 surfaces, the transmission shaft 341 of drive plate 34 is penetrated in the pivoted hole 121, promptly finish the assembling of transmission group 3; Assemble driving unit 2 again, rotating disk 22 is packed in the pedestal 21, pivot 331 is passed by the location division 222 of rotating disk 22, and allow first pushing part 223 be right against pushing and pressing part 211, then first elastic parts 26 and second elastic parts 27 are inserted in the registration mast 221 and location division 222 of rotating disk 22 respectively, and two second support divisions 271 that allow second elastic parts 27 be extended lay respectively at two sides of first pushing part 223 and pushing and pressing part 211, make the knock hole 251 of joggle piece 25 be articulated in registration mast 221 again, allow two first support divisions 261 of first elastic parts 26 be held in two sides in the joggle piece 25 respectively, and rotating part 24 penetrates pivot 331, make driving hole 242 be fastened in the clip engine part 332 of pivot 331, again spiral cover 23 is covered on rotating part 24 and joggle piece 25 surfaces, and allow set second pushing part 232 of rotating part 23 between two butting sections 41 of involution assembly 4, again left cap 11 is covered on spiral cover 23 surfaces at last, the stopper section 112 that makes left cap 11 and fixed part 113 fasten with the locating button 122 of right cap 12 respectively, and allow stopper section 112 between two butting sections 41 of involution assembly 4, and assembling of the present utility model is promptly finished for exposing hollow-out parts 111 in spiral cover 23 surfaces.

See also Fig. 2, shown in the 7-9, the use of seat lifting actuator described in the utility model is as follows: the user can utilize spiral cover 23 surperficial institute's bonded assembly handles (not shown) to drive spiral cover 23 turns, and spiral cover 23 is when turn, the set pushing portion of two sides 231 one of them, can promote an end of joggle piece 25 according to the turn direction, make joggle piece 25 produce deflection according to registration mast 221, and allow second tooth bar 241 of two engaging pieces 252 one of them and rotating part 24 form engagement (as shown in Figure 9), and then make pushing portion 231 when turn, promote joggle piece 25 and drive rotating disk 22 turns, and make joggle piece 25 drive rotating part 24 pivots; And when the user drives spiral cover 23 pivots, because the stopper section 112 of left cap 11 and second pushing part 232 of spiral cover 23 are all between two butting sections 41 of involution assembly 4, therefore second pushing part 232 of spiral cover 23 can promote two butting sections 41 one of them, another butting section 41 then is subjected to 112 backstops in stopper section and can't displacement, so that involution assembly 4 produces elastic deformation (as shown in Figure 8), and then has reset capability; And when joggle piece 25 deflection driving unit 2, joggle piece 25 can promote first elastic parts 26 two first support divisions 261 one of them, make first elastic parts 26 produce reset capability, and rotating disk 22 is when pivoting, its first pushing part 223 can promote second elastic parts 27 two second support divisions 271 one of them, make one second support division 271 produce elastic deformation, and another second support division 271 is subjected to supporting of pushing and pressing part 211 and can't interlock, and then makes second elastic parts 27 produce reset capabilities; Therefore, when the propulsive effort of spiral cover 23 is bestowed in user's removal, the butting section 41 that this involution assembly 4 is passed by first pushing part 223, promptly can move to another butting section 41 because of reset capability, and then promote first pushing part 223 and drive spiral cover to be returned to previous position, and when spiral cover 23 resets, the pushing portion 231 of spiral cover 23 can leave joggle piece 25, make joggle piece 25 be subjected to the reset capability of first elastic parts 26 and be returned to the not state of deflection, make second tooth bar 241 of engaging piece 252 disengaging rotating parts 24, and rotating disk 22 can promote to reset also because of second support division 271 of second elastic parts 27.

Please consult Fig. 1 again, 6, shown in the 9-11, find out by knowing among the figure, when rotating part 24 is subjected to joggle piece 25 engagements to promote to produce pivot, because the clip engine part 332 of eccentric shaft 33 engages (as shown in Figure 9) with the driving hole 242 of rotating part 24, therefore rotating part 24 can drive the pivot 331 generation pivots of eccentric shaft 33, and when eccentric shaft 33 pivots, because articulated section 333 is the out-of-alignment setting with pivot 331, therefore articulated section 333 can promote fluted disc 32 with fixing camber line pivot, and the 3rd tooth bar 323 of fluted disc 32 and first tooth bar, 311 engagements in the permanent seat 31 are rotated; And when fluted disc 32 pivots in permanent seat 31, the plural number that its surface was convexly equipped with takes off post and 321 also can do relative circular motion, and take off post 321 sense of motion of plural number is identical, because plural number takes off post and 321 lays respectively in the plural driving hole 342 of drive plate 34, therefore, when fluted disc 3232 pivots, also can promote drive plate 34 simultaneously pivots (as shown in figure 10) according to transmission shaft 341, as mentioned above, can utilize transmission shaft 341 to be connected, and then chair cushion is adjusted with the chair cushion of seat.

Moreover, because eccentric shaft 33 is when driving fluted disc 32 turns, the rotational force of fluted disc 32 apart from for be far longer than its surface set take off post 321, so the user can utilize lighter strength to drive driving unit 2, makes driving unit 2 drive eccentric shafts 33 and rotates.

The gordian technique of the seat lifting actuator that the utility model is realized is: utilize eccentric shaft 33 to drive fluted disc 32 turns, therefore fluted disc 32 can pivot with out-of-alignment in permanent seat 31, and then add the rotational force distance of large fluted disc 32, and what the fluted disc surface was set takes off post 321 when fluted disc 32 pivots, the moment that is produced is little than fluted disc 32, therefore the user can utilize lighter strength to drive driving unit 2, makes driving unit 2 drive eccentric shaft 33 and rotates.
