Abstract
An L-shaped driving structure of a digital camera lens comprises a motor, a worm matched with the output shaft of the motor and rotating around a horizontal axis and a turbine matched with the worm and rotating around a vertical axis. A coding disc is arranged at the front portion of the worm extending outside the turbine, the upper portion of the turbine matches with a reduction gear set arranged parallel to the motor, the reduction gear set is meshed with an output gear, and the turbine, the reduction gear set and the output gear are respectively matched with the shaft of the turbine, the reduction gear set and the output gear. The horizontal height of the shaft of the reduction gear set is larger than that of the shaft of the turbine, and the height of the shaft of the output gear is larger than the horizontal height of the shaft of the reduction gear set. The L-shaped driving structure of the digital camera lens is accurate in focal length control, compact in structure, has greater output torque, utilizes L-shaped arrangement, thereby saving spaces and being suitable for a circumstance where the camera lens is closer to the digital camera.
Description
Technical field
The utility model designs the unitized construction of a kind of gear case and motor, concretely, relates to a kind of flexible L type drives structure that is made of gear case and motor of digital camera lens that is used to drive.
Background technology
The digital camera lens drives structure generally is used to drive the flexible of retractable lens, thereby realizes zoom, regains the medium operation of camera lens overlay.Lens driving structure of the prior art generally comprises a motor, with the multi-stage speed-reducing gear of motor coupling, and goes out powershift gear with the final stage of reduction gearing engagement.The weak point of this structure is that motor need be set up in parallel with multi-stage speed-reducing mechanism, therefore, can not effectively save and hide the shared horizontal space of body structure.In the digital camera of some compact conformations, when especially distance of camera lens camera edge was nearer, to utilize limited space that drives structure is set then more harsh to the arrangement requirement of drives structure as far as possible.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of transmission direction that changes motor is provided, thereby changes the arrangement of motor and train of reduction gears, and the digital camera lens drives structure of saving the space by this arrangement.
For achieving the above object, the utility model provides a kind of L type digital camera lens drives structure, this L type digital camera lens drives structure comprises motor, the worm screw that cooperates with the output shaft of motor along the transverse axis rotation, the turbine that cooperates with worm screw along the Z-axis rotation, the part of stretching out turbine in the place ahead of worm screw is provided with code-wheel, the top of worm screw cooperates with the train of reduction gears that be arranged in parallel with motor, the train of reduction gears and the gearing mesh of exerting oneself, turbine, train of reduction gears and go out powershift gear cooperate respectively with separately the axle on, wherein, reduction gearing the axle level height greater than turbine the axle level height, and go out powershift gear the axle height greater than reduction gearing the axle level height.
According to such structure, when revolution, worm screw is driven by motor and rotates, turbine will be somebody's turn to do along rotatablely moving of horizontal axis and be converted into rotatablely moving along vertical axis, turbine is by the external tooth and the train of reduction gears engagement on its top, the deceleration increment, the final stage of train of reduction gears drives out powershift gear, and this goes out powershift gear for driving the flexible parts of camera lens.Some coding grooves can be arranged on the code-wheel of worm screw front portion, and the detection light that is used for the outside detects the rotational angle of motor, velocity of rotation etc.
L type digital camera lens drives structure of the present utility model is that a kind of focus controlling is accurate, compact conformation, big output torque digital camera lens drives structure.It adopts the L type to arrange, has saved the space, is applicable to the nearer situation in distance of camera lens camera edge.
Description of drawings
Fig. 1 looks cut-open view for the master of L type digital camera lens drives structure of the present utility model.
Fig. 2 is the L shaped cut-open view of overlooking of L type digital camera lens drives structure of the present utility model.
Embodiment
The utility model relates to a kind of L type digital camera lens drives structure, elaborates below in conjunction with the structure in Fig. 1, the 2 pairs of the utility model.
Comprise by upper shell 23 with reference to Fig. 1,2 L type digital camera lens drives structure of the present utility model, lower house 24 is by the fixedly composition shell of screw 29, is provided with in this shell by connecting worm component 18, worm component on the driving shaft of screw 30 fixed motor 31, motor and matches with turbine 19 that to be used for the rotational transform along horizontal axis be rotation along vertical axis.The end of worm screw is provided with code-wheel 191, and code-wheel is used to receive outside detection optical signal, infrared light for example, thus realize detection to the rotational angle and the rotating speed of motor.
Matching with worm screw in the bottom of turbine 18, is used for matching with the train of reduction gears of being made up of chopped-off head gear 20 and secondary gear 21 and top has external tooth.Secondary gear 21 is meshed with going out powershift gear 22, is meshed with the gear of camera lens and directly drives the flexible of camera lens thereby go out powershift gear.The gear of turbine and train of reduction gears and go out powershift gear and all be arranged at respectively in separately the rotating shaft 26,27.Wherein, reduction gearing the axle level height greater than turbine the axle level height, and go out powershift gear the axle height greater than reduction gearing the axle level height.
According to such structure, when revolution, worm screw is driven by motor and rotates, turbine will be somebody's turn to do along rotatablely moving of horizontal axis and be converted into rotatablely moving along vertical axis, turbine is by the external tooth and the train of reduction gears engagement on its top, the deceleration increment, the final stage of train of reduction gears drives out powershift gear, and this goes out powershift gear for driving the flexible parts of camera lens.On the code-wheel 191 of worm screw front portion some coding grooves can be arranged, the detection light that is used for the outside detects the rotational angle of motor, velocity of rotation etc.Code-wheel can link to each other with a signal plate 30, and imports aforementioned testing result to signal plate, and signal plate can send gating pulse to motor according to this result.
L type digital camera lens drives structure of the present utility model is that a kind of focus controlling is accurate, compact conformation, big output torque digital camera lens drives structure.It adopts the L type to arrange, has saved the space, is applicable to the nearer situation in distance of camera lens camera edge.
