For a further understanding of the nature and operation of the various elements of the invention, as well as the intended function and advantages thereof, reference should be made to the following detailed description and to the accompanying drawings, which are included to provide a further understanding of the invention.
As shown in fig. 1, fig. 2, fig. 3, fig. 5 and fig. 6, when the supporting plate 30 is at the retracted position, the first spring 60 and the second spring 70 are both in the stretched state, the maximum acting force of the first spring 60 is 96N (newtons), the maximum stretched length of the first coil section 63 is 210 mm, the maximum acting force of the second spring 70 is 88N, and the maximum stretched length of the second coil section 73 is 210 mm. That is, when the supporting plate 30 is in the retracted position, the maximum acting force of the first spring 60 is greater than the maximum acting force of the second spring 70. At this time, since the first positioning end 61 is located between the axis L and the supporting plate 30, the first positioning end 61 and the first elastic end 62 are respectively disposed at two sides of the axis L, the second positioning end 71 is located between the axis L and the supporting plate 30, and the second positioning end 71 and the second elastic end 72 are respectively disposed at two sides of the axis L, the supporting plate 30 can be kept at the retracted position due to the maximum acting forces of the first spring 60 and the second spring 70. At this time, the rotational angle of the damper 50 is set to 130 degrees.
Referring to fig. 1, 5, 6 and 7, when the operator pulls (manually pulls) the linking plate 22 through the pulling cable 24 and drives the driving shaft 21 to rotate relative to the leg-raising fixing plate 113 (the elastic member 23 is stretched and stores the releasing elastic force), the driving shaft 21 drives the first pivot end 411 of the first link 41 to rotate, and the first link 41, the second link 42, the third link 43, the fourth link 44 and the supporting plate 30 are pivoted with each other, so that the supporting plate 30 rotates from the folded position of fig. 6 to the leg-raising position of fig. 7, the rotation angle of the supporting plate 30 is 76.5 degrees, the rotation angle of the damper 50 is from 130 degrees to 205 degrees, and the resistance value is about 1.5kgf, thereby effectively suppressing the leg-raising opening speed. At this time, the tensile acting force of the first spring 60 is 36N, the tensile length of the first coil section 63 is 135 mm, the tensile acting force of the second spring 70 is 24N, and the tensile length of the second coil section 73 is 105 mm. The time required for the support plate 30 to rotate from the retracted position shown in fig. 6 to the leg-raising position shown in fig. 7 for opening is 1.5-2.5 seconds. That is, when the supporting plate 30 is in the leg-raising position, the stretching force of the first spring 60 and the stretching force of the second spring 70 are smaller than the maximum force of the first spring 60 and the second spring 70, the first positioning end 61 and the first elastic end 62 are between the axis L and the supporting plate 30, the second positioning end 71 and the second elastic end 72 are also between the axis L and the supporting plate 30, and the supporting plate 30 is under the elastic force of the first spring 60 and the second spring 70, and can be kept in the leg-raising position without falling down.
Therefore, by using different specifications of the first spring 60 and the second spring 70, when the support plate 30 is in the retracted position, the maximum acting force (96N) of the first spring 60 is greater than the maximum acting force (88N) of the second spring 70, and when the support plate 30 is in the leg-raising position, the tensile acting force (36N) of the first spring 60 is greater than the tensile acting force (24N) of the second spring 70, so that during the operation of the retracted position toward the leg-raising position, the first spring 60 and the second spring 70 are connected in parallel at the beginning, the elastic coefficients are added, the elastic force is greater, and when the leg-raising position is approached, the retracting elastic forces of the first spring 60 and the second spring 70 are weakened, so that a section of movement before the leg-raising position is softer, and besides avoiding generating a large impact force, the operation noise can be reduced, and furthermore, the damper 50 is installed at the middle section of the first link 41 and the 433 pivot of the third link 43 are matched to be pivoted at the middle section And the third link 43 is provided with a rotational damping when pivoting relative to the first link 41 and the second link 42 in the process of operating the folding position towards the leg-raising position, thereby avoiding generating a large impact force and reducing operating noise.
Conversely, when the operator presses the support plate 30 downward and operates the support plate 30 from the leg raising position to the retracted position, the support plate 30 can be smoothly operated to the retracted position by using the force and the self-weight to resist the elastic forces of the first spring 60 and the second spring 70. Also, by providing the damper 50, it is possible to prevent a large impact force from being generated and to reduce operation noise.
It should be noted that the installation positions of the first spring 60 and the second spring 70 of the present invention are not limited to those shown in the drawings, and in fact, the installation positions of the first spring 60 and the second spring 70 can be interchanged (not shown), and the functions and effects of the first spring 60 and the second spring 70 can be the same as those of the above-mentioned embodiments.
To sum up, the utility model discloses the seat leg lifting device utilizes manual linkage can reduce manufacturing cost, and utilizes the overall configuration can reach the purpose that manual operation is easy, the operation action is soft, can reach the purpose of the utility model with low costs really.
