Detailed description of the invention
Below in conjunction with accompanying drawing, provide preferred embodiment of the present utility model, and be described in detail.
Fig. 1 is the overall schematic of the seat 1 with lift system according to a preferred embodiment of the present utility model, and this seat 1 comprises to be sat basin 11 and sits basin frame assembly 12.Wherein, sit basin frame assembly 12 and comprise the two fixing seat tub wall plates 121 that are spaced apart from each other, sit tub wall plates 121 for these two and arrange in mirror image.Sit basin 11 to be installed on and to sit on basin frame assembly 12, its both sides are respectively by sitting basin pivotal axis 13 and sitting the pivot joint of tub wall plate 121, and making to sit basin 11 can sit basin pivotal axis 13 and do pivoting action round this.
This seat 1 also includes actuating unit 14 and matching mechanism 15, and for object clearly, dispense other structures of seat, Fig. 3 only illustrates the assembling completion status of this actuating unit 14 and matching mechanism 15.Composition graphs 1 is known, actuating unit 14 with sit basin frame assembly 12 and be connected, and matching mechanism 15 with sit basin 11 and be connected.Matching mechanism 15, by coordinating pivotal axis 16 (as shown in Figure 4) and actuating unit 14 pivot joint, makes matching mechanism 15 can do pivoting action round this cooperation pivotal axis 16.In use, actuating unit 14 provides power, drives matching mechanism 15 round cooperation pivotal axis 16 pivotable, due to matching mechanism 15 with sit basin 11 and be connected, thus drive sits basin 11 round sitting basin pivotal axis 13 pivotable, thus realizes lifting and the landing of seat.
As shown in Figure 5, this actuating unit comprises handle 141, heightens pump 142 and fixed support 143.Wherein, this handle 141 is rod-like members, and its one end is the free end that operator lifts and presses, the other end with heighten pump 142 and be connected.Composition graphs 1 and Fig. 2 known, fixed support 143 is fixed by screws in the inner side that is sat tub wall plate 121.Heighten pump 142 to be fixedly attached on fixed support 143, thus inside actuating unit 14 being fixedly connected at as a whole sit basin frame assembly 12 be positioned at the below sitting basin 11.This heightens pump 142 is a kind of known device, and its center has rotatable gear 1421 (see Fig. 5), can realize the rotation of this gear 1421 by lifting and press handle 141, and this part is that prior art repeats no more.
As shown in Figure 6, this matching mechanism 15 comprises transverse tube 151, supporting construction 152 and tooth plate 153.Wherein, supporting construction 152 comprises the two fixing back-up blocks 1521 that are spaced apart from each other, and these two back-up blocks 1521 are such as plastic buckle, arranges, and be fixedly connected on the below sitting basin 11 by screw in mirror image.Composition graphs 1 and Fig. 2 known, these two back-up blocks 1521 have through hole respectively, and transverse tube 151 is successively through these two through holes and the below being supported in and sitting basin 11 that is draped.Tooth plate 153 is quadrant, coordinates pivotal axis 16 (see Fig. 4) to run through the vertex position of this quadrant.One end of the arc of this quadrant is formed as contact jaw, and this contact jaw is fixed by welding with transverse tube 151.The other end of the arc of this quadrant is formed with sawtooth 1531, and this sawtooth 1531 engages with the gear 1421 heightening pump 142, as shown in Figure 7.In use, gear 1421 rotates due to the lift of handle 141 and pressing, sawtooth 1531 keeps engaging with it, thus make tooth plate 153 round cooperation pivotal axis 16 pivotable, because tooth plate 153 is connected with transverse tube 151, thus drive transverse tube 151 to rotate relative to cooperation pivotal axis 16, due to transverse tube 151 with sit basin 11 and be connected, thus drive sits basin 11 round sitting basin pivotal axis 13 pivotable, thus realize lifting and the landing of seat.
Composition graphs 1 and Fig. 2 known, this seat 1 also comprises the buffer gear 17 being arranged at and sitting basin 11 and sit between basin frame assembly 12.In the present embodiment, this buffer gear 17 is torsion spring.In the lifter motion of sitting basin 11, this torsion spring plays the effect of power-assisted, thus prevents from raising that resistance is excessive causes the too large and unworkable problem of force adjustment on handle.In the dropping motion sitting basin 11, this torsion spring plays the effect of resistance, thus prevents from lowering that resistance is too small causes force adjustment under handle too little and produce the problem of sense of falling, and reduces the risk progressively unlocked that may cause when automobile bumpiness simultaneously.
In brief, the rotary middle spindle (a) of gear 1421, sits basin pivotal axis 13 (b) and transverse tube 151 (c) is formed as three axles parallel to each other, and it defines three-link mechanism as shown in Figure 8.Obviously, compared with existing four-bar linkage, three-link mechanism structure of the present utility model is simple and with low cost, and the deadweight of this three-link mechanism is comparatively light, and required installing space is less.
Above-described, be only preferred embodiment of the present utility model, and be not used to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Namely every claims according to the utility model application and description are done simple, equivalence change and modify, and all fall into the claims of the utility model patent.The not detailed description of the utility model be routine techniques content.
