Abstract
The utility model relates to the field of optical lenses and provides a transmission structure of an imaging instrument electric lens. The transmission structure of the imaging instrument electric lens comprises transmission gears, an optical lens, an electric motor, an electric lens fixing block and two optical sensors. The transmission gears are arranged on the bottom of the electric lens fixing block. There are two transmission gears. The two transmission gears are engaged with each other. One transmission gear has the center fixed with the rotating shaft of the electric motor. A baffle plate is fixed on the upper surface edge of the transmission gear. The baffle plate protrudes from the outer edge of the transmission gear. The baffle plate contacts a connecting wire between the transmitting port and the receiving port of the optical sensors. Two transmission gears are adopted for engaging transmission. The lens distance adjusting process will be more stable. The adjustment is more accurate. Meanwhile, the baffle plate is arranged on one of the gears. When the gear is rotated in a way that the baffle plate is located between the transmitting port and the receiving port of the optical sensors and blocks signals, the gear is then controlled to stop rotating. A limiting function for automatically controlling the lens focusing motion is thus achieved.
Description
Technical field
The utility model relates to field of optical lens, particularly a kind of motor-driven lens drive mechanism.
Background technology
Traditional motor-driven lens driving mechanism is driven by the gear more than three or three, it has by using identification switch to carry out the identification of initial or half-way, and because such as the high focusing accuracy of still life and the detection of relevant enlargement factor, gear uses more manyly, though degree of accuracy can improve, but its accuracy will correspondingly reduce, under this kind occasion, its demand is more special, thereby use the motor-driven lens than multi-gear to be subjected to certain restriction, along with the rotation of gear is carried out, its error will enlarge so that accuracy detects inaccurate all the more.The control of focusing simultaneously, is also comparatively complicated in the middle of common structure.
The utility model content
The utility model provides a kind of more stable motor-driven lens structure of process of adjusting distance of camera lens at the deficiency in the above-mentioned background.
The technical scheme of its realization is as follows:
A kind of drive mechanism of simple and easy image instrument motor-driven lens, comprise transmission gear, optical lens, electro-motor, motor-driven lens fixed block and two optical sensors, transmission gear is arranged at the bottom of motor-driven lens fixed block, described transmission gear is two, two transmission gears are meshing with each other, wherein the rotating shaft of the center of a transmission gear and electro-motor is fixed, the top surface edge of this transmission gear fixedly has a baffle plate, described baffle plate stretches out the outward flange of transmission gear, and baffle plate touches the line at place between the emission port of optical sensor and the receiving port.
Further, the center of another transmission gear is a space of passing described optical lens, and the edge in the space of transmission gear and optical lens are fixed.
Further, described electro-motor is fixed in the top of motor-driven lens fixed block.
Preferably, described optical sensor is arranged at the both sides of transmission gear position engaged.
The beneficial effects of the utility model are: general motor-driven lens is with 3 transmission gears, and 2 transmission gears of this novel use carry out meshing transmission, owing to reduced by a middleware, camera lens is adjusted the process of distance will be more stable, and adjusting will be more accurate also; On the gear baffle plate is set therein, when gear forwards to when blocking signal between emission that baffle plate is in optical sensor, the receiving port, gear is controlled and stop operating, thereby reaches the limit function of automatic control camera lens focusing action.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is electronic drive mechanism figure of the present utility model.
Embodiment
With reference to shown in Figure 1, a kind of drive mechanism of simple and easy image instrument motor-driven lens, comprise transmission gear 1, optical lens 2, electro-motor 3, motor-driven lens fixed block 4 and two optical sensors 5, transmission gear 1 is arranged at the bottom of motor-driven lens fixed block 4, described transmission gear is two, two transmission gears are meshing with each other, and wherein the rotating shaft of the center of a transmission gear and electro-motor 3 is fixed.The top surface edge of this transmission gear fixedly has a baffle plate 6, and described baffle plate stretches out the outward flange of transmission gear, and baffle plate 6 touches the line at place between the emission port of optical sensor and the receiving port.Preferably, described optical sensor 5 is arranged at the both sides of two transmission gears, 1 position engaged.
Further, the center of another transmission gear is a space of passing described optical lens 2, and the edge in the space of transmission gear 1 and optical lens 2 is fixing.
Further, described electro-motor 3 is fixed in the top of motor-driven lens fixed block 4.
The utility model arranges baffle plate on the gear therein, when when baffle plate is in the emission, receiving port of optical sensor by the rotation of transmission gear 1 between, blocking signal, transmission gear then stops to continue to rotate toward former direction, and can only rotate to the other end, thereby reach the position-limiting action of the focusing action of automatic control camera lens.
The announcement of book and enlightenment according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the embodiment of above-mentioned announcement and description, and the basic transformation of all various mechanisms that do based on this patent also should be included in the protection domain of claim of the present utility model.In addition, although used some specific terms in this instructions, these terms can not constitute any restriction to the utility model just for more convenient explanation.
