In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be mechanical connection, can be to be also electrically connected to; Can be to be directly connected, also can indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.
Although traditional camera possesses the anti-shake function of optics already, and relevant technology and device sell in market already, yet it is still also immature compared with the anti-shake technology of the optics of small mobile terminals to can be used in mobile phone etc.Main cause is that the mechanical space of anti-shake motor is little, relevant design is subject to the restriction in space, if the position of shell fragment fixed position changes, to cause the mechanical force of motor to change thereupon, mechanical force cannot reach consistent with electromagnetic force, causes camera module in focusing process, to produce the unsettled phenomenon of focusing.
Now in disclosed patent document, never relate to the solution of above-mentioned phenomenon.Therefore,, when mechanical force cannot reach theory and requires, not timely, thoroughly effectively indemnifying measure, can only not revise by the parts to other, to reach the object of optimizing mechanical force.Yet, this method length consuming time, poor reliability, engineering are many, have increased greatly the cost of product, have elongated the design cycle, have weakened the competitiveness of product in market.Existing optimization method major defect is as follows:
The first, existing product space coordinates relative compact, causes shell fragment fixed position to occur do not have space allocation parts relatively flexibly to carry out the compensation of distance after relative displacement, and the mechanical force of motor and theoretical value are not inconsistent, and has directly affected the function of motor.
The second, shell fragment directly contacts with mechanism arrangement, and while causing scolding tin due to the restriction of material, the increasing of technology difficulty and then shell fragment distortion increase, and engineering loss strengthens, and production cost improves, and product yield is lower.
The 3rd, space deficiency has caused being seriously decreased to of focussing distance to make camera lens zoom in or out multiplying power minimizing, causes properties of product greatly to decline.
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figures 1 to 6, the utility model provides a kind of anti-shake camera module, comprising:
