Abstract

The utility model provides a lens driving device, which comprises a lens frame for holding the lens, a shell for holding the lens frame, a magnet arranged in the shell and an elastic device fixed on the lens frame. The shell comprises a base and an upper cover. A groove is arranged on the base. The lens frame is provided with a bump. Interference fit is carried out between the groove and the bump. The lens driving device can prevent the lens tube from rotating and protect the elastic device from being damaged.

Description

Lens driving apparatus
[technical field]
The utility model relates to a kind of lens driving apparatus, but relates in particular to a kind of lens driving apparatus of self anti-rotation loss prevention.
[background technology]
Continuous development along with science and technology, products such as digital camera, mobile phone camera or Digital Video are more and more higher to the requirement of zoom, focusing in the digital vedio recording field, at the image that guarantees high image quality simultaneously, volume requirement to zoom, focalizer is also more and more stricter, and zoom, focalizer develop towards microminiaturized direction.
The lens driving apparatus of correlation technique, comprise camera lens, elastic device, stationary installation and the lens bracket of accommodating camera lens, its lens bracket links to each other with the elastic device inner ring, elastic device is a spring leaf, when screwing in camera lens, because the rubbing action of lens bracket and camera lens screw thread rotates lens bracket, thereby drive radially stretching of spring leaf.Moment of torsion is excessive then to make spring leaf generation plastic deformation easily, thereby destroys spring leaf.
Therefore, make and be necessary to provide a kind of novel lens driving apparatus.
[utility model content]
The technical matters that the utility model need solve provides the lens driving apparatus of the anti-rotation and spring leaf loss prevention of a kind of lens bracket.
For solving the problems of the technologies described above, the utility model provides a kind of lens driving apparatus, comprise the lens bracket of accommodating camera lens, accommodate the housing of lens bracket, place the magnet in the housing and be fixed in elastic device on the described lens bracket, described housing comprises pedestal and loam cake, described pedestal is provided with and the extraneous outside surface that contacts, with outside surface corresponding towards elastic device inside surface and run through outside surface and the through hole of inside surface, described inside surface is provided with groove at described through hole edge, described lens bracket is provided with the bottom surface towards inside surface, described bottom surface is provided with projection, groove and projection interference fit.
Preferably, described elastic device is spring or leaf spring.
Preferably, described pedestal and loam cake are square, and described magnet is arranged at described square place, four angles.
The beneficial effects of the utility model are: on the fixed part pedestal groove is set, cooperates with the projection that is provided with on the lens bracket, play the effect of firm lens bracket, and the moment of torsion that it is born is bigger, prevent around the elastic device of lens bracket impaired simultaneously.
[description of drawings]
Fig. 1 is the utility model lens driving apparatus one embodiment three-dimensional exploded view;
Fig. 2 is the utility model lens driving apparatus one embodiment stereographic map;
Fig. 3 is the utility model lens driving apparatus one embodiment pedestal front view.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As Figure 1-3, be the utility model one embodiment lens driving apparatus, comprise the lens bracket 4 of accommodating camera lens, accommodate the housing 100 of lens bracket 4, place the magnet 3 in the housing 100 and be fixed in elastic device 5 on the described lens bracket 4, described housing 100 comprises pedestal 1 and loam cake 2, described pedestal 1 is provided with and the extraneous outside surface that contacts (not indicating), with outside surface corresponding towards elastic device 5 inside surface 12 and run through outside surface and the through hole of inside surface 12 11, described inside surface 12 is provided with groove 10 at described through hole 11 edges, described lens bracket 4 is provided with the bottom surface 42 towards inside surface 12, described bottom surface 42 is provided with projection 40, groove 10 and projection 40 interference fit.
In the utility model lens driving apparatus, described elastic device 5 is two flat springs of fixing around lens bracket 4 up and down, and certain described elastic device 5 also can be leaf spring; Described pedestal 1 is square with loam cake 2, and described magnet 3 is four, is individually fixed on described four square angles, and certainly, described pedestal 1 can also be other shapes with loam cake 2; The quantity of described groove 10 and projection 40 is equal and the position is corresponding one by one, and its quantity can be individual arbitrarily.
In above-mentioned the utility model embodiment, groove 10 is set on pedestal 1, cooperate with the projection 40 that is provided with on the lens bracket 4, when lens bracket 4 rotated, the groove 10 on the pedestal 1 was dead with its retaining, stops its further motion; Prevent around the elastic device 5 of lens bracket 4 impairedly simultaneously, and the moment of torsion that it is born is bigger.
Above-described only is embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection domain of the present utility model.
