Description
Technical field
The utility model relates to lens driver technical field, particularly relates to a kind of lens driver yoke assembly structure.
Background technology
Lens driver generally comprises stator module and base, yoke assembly is had in stator module, leaf spring is provided with in yoke assembly, base is positioned at yoke assembly and is provided with coil holder, the outside of coil holder is provided with coil, camera lens is installed in coil holder inside, lower leaf spring is provided with between coil holder and base, before not being energized, the two ends up and down of coil holder (camera lens) respectively by upper leaf spring, lower leaf spring floating position-limiting, when after coil electricity, magnetic field is produced in coil, magnetic field and yoke effect, make coil holder move along optical axis direction, thus realize the focusing of camera lens; When after power-off in coil, camera lens resets under the effect of upper leaf spring, lower leaf spring.But in present lens driver, upper leaf spring is directly installed on yoke inside, so just causes leaf spring that trouble is installed, and in installation process, also easily cause leaf spring to be out of shape, thus affect lens focusing precision; Simultaneously during each focusing mobile, position all possibility changes of upper leaf spring, thus cause camera lens optical axis to produce deflection.
Utility model content
The utility model, in order to solve the aforementioned problems in the prior, provide a kind of leaf spring and installs stable, leaf spring and coil holder between mutually produce displacement when preventing from focusing at every turn, ensures the lens driver yoke assembly structure of each focusing accurate stable.
To achieve these goals, the utility model adopts following technical scheme:
A kind of lens driver yoke assembly structure, comprise yoke housing, be located at the magnetite in yoke housing, also comprise leaf spring, upper cover, four angles of described yoke housing upper surface are provided with connecting hole, described upper cover the inner is provided with the joint pin corresponding with connecting hole, the end of described joint pin is provided with hot melt riveting portion, four angles of described yoke housing upper surface are also provided with four and dodge counterbore, the spring silk of described leaf spring is bent to form positioning boss with four corresponding positions of dodging counterbore, the inner side of described upper cover with dodge counterbore corresponding position and be also provided with four contiguous blocks, contiguous block is provided with reference column, the diameter of described reference column is the 1/5-1/3 dodging counterbore aperture.
Upper cover and yoke housing are clipped in the middle leaf spring, the spring silk of leaf spring there are four positioning boss, positioning boss snaps in dodges in counterbore, positioning boss is bent to form by spring silk, the opposite face of positioning boss crowning is location dimples, reference column in upper cover stretches in location dimples, thus prevent from, between leaf spring and yoke housing, relative movement occurs, in leaf spring, ring spring silk is pressed on coil holder (lens mount pad), during coil holder focusing mobile, leaf spring is due to complete positioning stablity, therefore and between coil holder relative movement is not had, thus state when ensureing that each coil holder moves is all same stable, accurate stable when ensureing at every turn to focus.
As preferably, described reference column is spring catch, and the end face of described spring catch is sphere.When spring catch is installed, energy automatic telescopic, prevents reference column oversize or too short and impact assembling.
As preferably, the surrounding of described leaf spring is provided with sealing ring, and the inner ring of described sealing ring is provided with annular slot, and described yoke housing, the joint face of upper cover are provided with the seal groove coordinated with sealing ring.Around leaf spring, cover has sealing ring, and during installation, sealing ring snaps in seal groove, and sealing ring plays sealing function to upper cover, yoke housing junction, also plays assist location effect to leaf spring simultaneously.
Therefore, the utility model has leaf spring and installs stable, mutually produces displacement when preventing from focusing between leaf spring and coil holder at every turn, ensures the beneficial effect of each focusing accurate stable.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of lens driver yoke assembly structure as depicted in figs. 1 and 2, comprise yoke housing 1, the magnetite be located in yoke housing, also comprise leaf spring 2, upper cover 3, four angles of yoke housing upper surface are provided with connecting hole 4, upper cover the inner is provided with the joint pin 5 corresponding with connecting hole, the end of joint pin is provided with hot melt riveting portion 6, four angles of yoke housing upper surface are also provided with four and dodge counterbore 7, here, the mode that hot melt riveting portion 6 also can not take hot melt to rivet connects, and change glue into even, also can reach the effect of connection.As shown in Figure 3 and Figure 4, the corresponding position of the spring silk of leaf spring being dodged counterbore with four is bent to form positioning boss 8, the inner side of upper cover with dodge counterbore corresponding position and be also provided with four contiguous blocks 9, contiguous block is provided with reference column 10, the diameter of reference column is the 1/5-1/3 dodging counterbore aperture, reference column 10 in the present embodiment is spring catch, and the end face of spring catch is sphere, and the diameter of spring catch is dodge counterbore aperture 1/4; As shown in Figure 5, the surrounding of leaf spring 2 is provided with sealing ring 11, the inner ring of sealing ring is provided with annular slot 12, the joint face of yoke housing, upper cover is provided with the seal groove 13 coordinated with sealing ring, around leaf spring, cover has sealing ring, and during installation, sealing ring snaps in seal groove, sealing ring plays sealing function to upper cover, yoke housing junction, also plays assist location effect to leaf spring simultaneously.
Upper cover and yoke housing are clipped in the middle leaf spring, the spring silk of leaf spring there are four positioning boss, positioning boss snaps in dodges in counterbore, positioning boss is bent to form by spring silk, the opposite face of positioning boss crowning is location dimples, reference column in upper cover stretches in location dimples, thus prevent from, between leaf spring and yoke housing, relative movement occurs, in leaf spring, ring spring silk is pressed on coil holder (lens mount pad), during coil holder focusing mobile, leaf spring is due to complete positioning stablity, therefore and between coil holder relative movement is not had, thus state when ensureing that each coil holder moves is all same stable, accurate stable when ensureing at every turn to focus.Therefore, the utility model has leaf spring and installs stable, mutually produces displacement when preventing from focusing between leaf spring and coil holder at every turn, ensures the beneficial effect of each focusing accurate stable.
