Detailed description of the invention
Further illustrate the detailed description of the invention of a kind of rocking arm driver plate of the utility model location structure below in conjunction with accompanying drawing, but it is noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 2 and 3.A kind of rocking arm driver plate location structure, containing rocking arm driver plate 1 and housing 2.Described rocking arm driver plate 1 arranges feature holes 5, feature groove 7 and second feature axle 8.Described feature holes 5 is semi-circular through hole and the bore size of one end is larger than the bore size of all the other positions, and described feature holes 5 is through the surface 6 of rocking arm driver plate 1.Total bore size of described feature holes 5 semi-circular through hole be operating angle 501, safe clearance 502 and angle of assembling 503 sum (see Fig. 8) (
note:described operating angle 501, safe clearance 502 and angle of assembling 503 are design process values of feature holes 5, and on described rocking arm driver plate 1, do not have the outward appearance boundary of these three angles.In enforcement of the present utility model, operating angle 501 is 116 °, and safe clearance 502 is 22.5 °, and angle of assembling 503 is 59.5 °.But in a particular application, the occurrence of described operating angle 501, safe clearance 502 and angle of assembling 503 can also should adjust according to actual conditions, wherein, the concrete angle that operating angle 501 is rotated by HVAC air door determines; In angle of assembling 503 scope feature holes 5 second in hole width be d, in in operating angle 501, safe clearance 502 scope first, hole width is c, described d > c, that is, the bore size of one end of the feature holes 5 of semi-circular through hole is larger than the bore size of all the other positions).Described feature groove 7 is cylindrical structural.Described second feature axle 8 is arranged on one end (see Fig. 6) of described rocking arm driver plate 1.
Described housing 2 arranges feature back-off 3 and fisrt feature axle 4.Described feature back-off 3 is by back-off and draw wall two parts to form, and the width of described back-off is a, described in draw the width of wall to be that b(is see Fig. 5); Described back-off width a be less than feature holes 5 in angle of assembling 503 scope second in hole width d, be greater than hole width c in first in operating angle 501, safe clearance 502 scope; The described wall width b that draws to be less than in first hole width c(see Fig. 8).Thus when assembling, described feature back-off 3 can in the scope of angle of assembling 503 through described feature holes 5(see Fig. 6), and do not deviate from feature holes 5 in the scope of operating angle 501 and safe clearance 502.Described fisrt feature axle 4 is ring-shaped cylinder structure (see Figure 4 and 5).
Continue and see Fig. 2 and 3.Described rocking arm driver plate 1 by feature groove 7(see Fig. 7) carry out hole axle with the fisrt feature axle 4 of described housing 2 and coordinate, described rocking arm driver plate 1 freely can be rotated: described feature back-off 3 is buckled in (see Fig. 4) on the surface 6 of rocking arm driver plate 1 through described feature holes 5, makes can not depart from housing 2 in the rotational travel of rocking arm driver plate 1 around the fisrt feature axle 4 of described housing 2.
Described rocking arm driver plate 1 is connected by other connecting rod of second feature axle 8 and HVAC or air door, thus the rotation of rocking arm driver plate 1 is limited within the scope of certain operating angle.It is pointed out that rocking arm driver plate 1 can have various ways with the connection of connecting rod on HVAC or air door.In concrete enforcement; rocking arm driver plate 1 might not all by the form of second feature axle 8 of the utility model statement; described second feature axle 8 is only used to illustrate that rocking arm driver plate 1 can be connected with other connecting rods or air door on HVAC, and not limit this be unique connection mode.
The mode of operation of a kind of rocking arm driver plate of the utility model location structure is:
(1) the feature groove 7 of rocking arm driver plate 1 is enclosed within (see Fig. 3) on the feature axis 4 of housing 2.
(2) rotating arm driver plate 1, makes the feature back-off 3 of housing 2 roughly be aligned in the big opening end of rocking arm driver plate 1 feature holes 5, i.e. the scope interior (see Fig. 8) of angle of assembling 503.
(3) by rocking arm driver plate 1 moving axially along housing 2 feature axis 4, the feature back-off 3 of housing 2 is made to be buckled in the surperficial 6(of rocking arm driver plate 1 see Fig. 4 through the feature holes 5 of rocking arm driver plate 1).
(4) rotating arm driver plate 1, makes feature back-off 3 be within the scope of feature holes 5 operating angle.
(5) the second feature axle 8 of rocking arm driver plate 1 is connected with other connecting rod of HVAC or air door, has assembled (see Fig. 6).
(6) after having assembled, in the actual use procedure of HVAC, described rocking arm driver plate 1 can rotate by demand, because rocking arm driver plate 1 is connected by other connecting rod of second feature axle 8 and HVAC and rocking arm, so; the slewing area of rocking arm driver plate 1 can be limited within the scope of the operating angle of design: described feature back-off 3 is buckled on the surface 6 of rocking arm driver plate 1 all the time, the slewing area of rocking arm driver plate 1 is limited in operating range all the time, can not departs from housing 2.
(7) when needing dismounting HVAC, first other connecting rod of HVAC or air door are separated with the second feature axle 8 of rocking arm driver plate 1, then rocking arm driver plate 1 is rotated, make feature back-off 3 be aligned in the position of feature holes 5, then rocking arm driver plate 1 is axially pulled out along fisrt feature axle 4.
The foregoing is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model structure; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
