In figure: yoke body 1, yoke top board 11, yoke through hole 12, frame are by horizontal platform 13, plate chamber 14, spacing rim 141, pressing plate 15, the horizontal limiting plate of leaf spring 151, leaf spring lower limiting board 152, rotation protection section 153, adjustment reed 16, upper shell fragment 2, hollow bulb 21, compression protuberance 22, housing 3, interior spacing gusset 4, riser 41, wing plate 42, horizontal platen 5, anticreep limiting section 51.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment 1: as Fig. 1, Fig. 2, in embodiment shown in Fig. 3, plate spring part structure in a kind of yoke of lens driver, comprise yoke body 1, upper shell fragment 2, described yoke body 1 comprises housing 3, interior limiting section, described housing 3, interior limiting section is connected by yoke top board 11, described housing 3 is provided with yoke through hole 12, described housing 3 is continuous and head and the tail close formation ring, described interior limiting section is made up of some interior spacing gussets 4, interrupted overdose space is spaced apart between adjacent interior spacing gusset 4, described interior spacing gusset 4 comprises one facing to the riser 41 of yoke corner and two blocks of wing plates 42, the two blocks of wing plates 42 being subordinate to spacing gusset 4 in are parallel to two connected housing 3 sidewalls respectively, described upper shell fragment 2 comprises a hollow bulb 21, described upper shell fragment 2 to be set on interior limiting section and to be between housing 3 and interior limiting section, described upper shell fragment 2 outer rim is provided with some compression protuberances 22 outwardly, each compression protuberance 22 holds out against a madial wall of housing 3.Described compression protuberance 22 total number is eight, each upper shell fragment 2 lateral margin has two compress protuberance 22.
In adjacent two, spacing gusset 4 having respectively has one block of wing plate 42 to be towards relative, can be used as the spacing of a direction.Multiple interior spacing gusset 4 constitutes the interior spacing of shell fragment 2, after upper shell fragment 2 is inserted in interior limiting section, compress mutually with it, multiple interior spacing gusset 4 is outwards exerted pressure simultaneously, can shell fragment 2 on effective location, multiple compression protuberances 22 in upper shell fragment 2 outer rim compress by housing 3 simultaneously, locate inside and outside formation simultaneously, fully ensure the firmly firm of upper shell fragment 2.
Embodiment 2: the basic structure of the present embodiment and execution mode are with embodiment 1, its difference is, as shown in Figure 4, described yoke body 1 is provided with and compresses the equal corresponding plate chamber 14 of protuberance 22 number and position, pressing plate 15 is provided with in described plate chamber 14, two adjustment reeds 16 are provided with between described pressing plate 15 and yoke body 1, the protrusion direction of two adjustment reeds 16 is contrary, described reed is all connected with pressing plate 15, housing 3 madial wall, and described outer end, plate chamber 14 is provided with the spacing rim 141 leaving plate chamber 14 for limiting pressing plate 15.Described pressing plate 15 comprises the horizontal limiting plate 151 of leaf spring, leaf spring lower limiting board 152; described leaf spring lower limiting board 152 stretches out outside plate chamber 14; rotate protection section 153 by one between the horizontal limiting plate 151 of described leaf spring, leaf spring lower limiting board 152 to connect; be provided with the horizontal platen 5 contacted with leaf spring lower limiting board 152 bottom surface outside described plate chamber 14, described horizontal platen 5 is provided with anticreep limiting section 51.
The protrusion direction of two adjustment reeds 16 is contrary, therefore has certain for becoming second nature, and can bear the pressure that is not orthogonal to pressing plate 15 preferably and be unlikely to cause because of oblique pressure pressing plate 15 to misplace the problem such as stuck.Pressing plate 15 number and position corresponding with plate chamber 14, therefore each pressing plate 15 for contact one compress protuberance 22.During contact, regulate reed 16 compressive deformation.If directly compress between compression protuberance 22 and housing 3 mutually, cause because of oversize housing 3 to be out of shape excessively sometimes, now easily damage yoke body 1, and the existence of shell fragment, deflection has all been transferred to self, and the stress deformation on housing 3 is limited all the time, thus not easily damaged.And sometimes, due to unavoidable causes such as workman's carelessness, when upper shell fragment 2 is loaded yoke body 1 at the very start at a slant, pressing plate 15 upper end being in this side will certainly excessively be headed into plate chamber 14 by the downward-sloping side of upper shell fragment 2, now these are by two reeds that the pressing plate 15 that excessively heads into is ined succession, that reed deflection is above large, that reed deflection is below little, thus can promote rotate protection section 153 slide towards the direction away from plate chamber 14, rotate, cause leaf spring lower limiting board 152 no longer level, but be upturned, withstand the upper shell fragment 2 moved down, now operator will find that shell fragment 2 not only tilts, and installation can not be continued entered, need upwards to regain certain distance, allow and regulate reed 16, pressing plate 15 resets, and then by the loading yoke body 1 of upper shell fragment 2 comparatively level, just assembly manipulation can be completed.So, reduce the possibility that housing 3 is impaired, further increase assembly connection effect, and assembling process is protected, avoid assembling the situation such as shell fragment 2 out-of-flatness in rear appearance.
