The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Seeing Fig. 1---concrete structure and principle that Fig. 2, the utility model automotive seat increase pump are following:
Be fixed with shell 30 on the fixed mount 10, shell 30 tightens together through screw 130 with lid 20, and fixed mount 10, shell 30 have cooresponding through hole respectively.
Include with lower component in the space between shell 30 and the lid 20: tooth axle 40, fluted disc 50, handle 60, ratchet 70, ratchet spring 80, leaf spring 90, ball 100, spring chair 110, rivet 120.
Wherein, Tooth axle 40 is sheathed in the shell 30, and shown in figure, the main body 41 of tooth axle 40 is hexagon; Along on the axis direction of main body 41; The upper surface of tooth axle 40 has cylinder 42, the lower surface has the tooth 43 of commentaries on classics, changes the through hole that tooth 43 passes fixed mount 10, shell 30 respectively, is used for being connected with outside seat unit.
Fluted disc 50 is sheathed on outside the tooth axle 40; The upper surface protrusion of fluted disc 50 forms the disk 51 with tooth limit; The lower surface of fluted disc 50 has 6 projections 52 of well-distributed; Be embedded with two balls 100 between two adjacent projections 52 and in tooth axle 40 and the shell 30 mutual cracks of forming, promptly corresponding two balls 100 in each bar limit of tooth axle 40 are folded with spring chair 110 between cooresponding two balls 100 in each bar limit; Ball 100 cooperates with tooth axle 40 realizes the position locking, and the locking effect of the utility model is better.
Fluted disc 50 middle parts offer through hole, and the cylinder 42 of the upper surface of tooth axle 40 passes this through hole of fluted disc 50.
The lid 20 of the utility model is similar with common cover substantially.Lid 20 has depression platform 21 towards the lower surface of shell 30 1 sides; A part that is actually the side of lid 20 is not sealed and is formed; The two ends of untight part form retaining portion 25; This depression platform 21 provides revolution space for handle 60, that is, handle 60 can only rotate in this caves in platform 21 formed angular ranges; That is be the anglec of rotation that limits handle 60 through the retaining portion 25 at two ends, the concrete corner dimension that this depression platform 21 is provided can change according to designer's requirement.
For increasing result of use, leaf spring 90 outwards forms a plurality of lug bosses, both can increase the resistance to deformation power of self, can realize friction location fast again.
The lower surface of handle 60 is equipped with ratchet 70, and ratchet 70 front ends are that movable end, rear end are fixed end, and the fixed end of ratchet 70 is riveted on the handle 60 through rivet 120, and ratchet 70 can rotate around this rivet 120; The movable end of ratchet 70 has tooth portion 71, and the movable end of ratchet 70 is provided with the locating dowel pin 72 vertical with tooth portion 71, and locating dowel pin 72 is parallel with rivet 120; The tooth portion 71 of the movable end of ratchet 70 and 51 engagements of the disk with tooth limit of fluted disc 50 upper surface moulding.
Concrete; Outwards protrusion is formed with position-limited trough 22 on the depression platform 21 of lid 20; In product when assembling,, the locating dowel pin 72 of ratchet 70 promptly embeds in this position-limited trough 22, and position-limited trough 22 is used to limit the moving of locating dowel pin 72 of ratchet 70; This position-limited trough 22 is identical with the motion track of locating dowel pin 72, and is all curved.
The handle 60 of the utility model drives two ratchets 70; One of them ratchet 70 is realized the positive dirction driving, and another ratchet 70 realizes that reversing senses drive, thereby realizes the rising and reduction control of seat; For realizing the control effect; These two ratchets 70 are symmetrical set, and between these two ratchets 70 ratchet spring 80 are installed, promptly can provide handle 60 just changeing, when reversing to the control of seat.
Further; For handle 60 just being changeed, driving fluted disc 50 through 70 work of different ratchets when reversing; Position-limited trough 22 two ends at lid 20 form limiting section 23 respectively, and position-limited trough 22 is used to supply the locating dowel pin 72 of ratchet 70 to move, so the width of position-limited trough 22 is than the somewhat larger in diameter of locating dowel pin 72; And limiting section 23 is slightly wide and longer than the diameter of locating dowel pin 72 than position-limited trough 22, forms the structure of similar step; Principle of work is, when the locating dowel pin 72 of one of them ratchet 70 was positioned at limiting section 23 and limited 23 and stops, another ratchet 70 can be realized the driving that is rotated in the forward to fluted disc 50, otherwise, then can realize the contrarotation of fluted disc 50 is driven.
The utility model realization is just changeed, the principle of inversion driving seat ascending, descending control is:
The releasing action of the locating dowel pin of realizing being stopped 72; The firmly rotation of direction of the locating dowel pin 72 that only needs handle 60 is stopped to this quilt; Make locating dowel pin 72 separate and break away from stopping of limiting section 23 with step; The ratchet 70 that stops of this quilt is got back to rapidly in the position-limited trough 22 under the effect of ratchet spring 80 simultaneously;
Continuation is rotated handle 60 to ratchet 70 directions that originally do not stopped; When the locating dowel pin 72 of this ratchet that is not stopped 70 entered into the limiting section 23 that is positioned at this side, under the effect of ratchet spring 80, the locating dowel pin 72 and the step of this ratchet that is not stopped 70 offseted; Rotated by stopping no longer of limiting section 23; At this moment, this ratchet 70 is promptly limited, accomplishes the mode of operation conversion of two ratchets 70.
The utility model terminal with compact integral structure can reach and the external identical result of use of like product.
Certainly; The embodiment of the above; It is the preferred embodiments of the utility model; And unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify, all should be included in the utility model claim.
