Description

Camera lens module

Technical field

The utility model relates to image capture unit, particularly a kind of camera lens module of digital imaging apparatus.

Background technology

The invention of digital camera has revolutionary impact power with use to the activity of taking pictures, and photographer can be not be used in wash egative film in the dark place hard.Behind the camera lens pick-up image of photographer, under the processing of image via photosensory assembly and microprocessor, promptly can be stored in the internal memory of digital camera with the pattern of numerical data by digital camera.So photographer just can be stored in the photo of digital kenel the hard disk of computer installation or with oneself in the dish, also can utilize the image editing software on the computing machine voluntarily this digital photo to be compiled by transmitting device, quite make things convenient for and save time economical.Under the scale of mass production of camera manufacturer, the unit price of many consumption-orientation digital cameras also gradually by general popular acceptance, improves constantly the popularity rate of digital camera.In addition, owing to developing rapidly of semiconductor technology and optical module, the volume of imaging lens dwindles widely, and can generally be used for all kinds of consumption electronic products, as portable computer, mobile phone, hand held Game device or the like.

Camera lens occupies critical role in the camera imaging process, make the shooting effect of camera and getting well with bad of image quality often also depend on camera lens, so camera lens can be described as optical element the most key in the camera.In general, in the camera lens optics spare part and the electronics spare part accurate as aperture blades, lens set, driving circuit, step motor or the like can be set, be very big knowledge so how camera lens firmly is fixed on camera body and suitable protection is provided.With regard to now on the market with regard to the consumption-orientation camera product, be to adopt fixing and non-exchange camera lens.This type of fixed camera lens is to combine with the fuselage of camera in solid-state bond mode (directly engaging or the suspension winding) mostly, though good fixedly function can be provided, makes camera lens be assembled in the fuselage of camera securely.

But; lack at camera lens and camera body under the mechanism of shock-absorbing, when camera meets with when impacting or when rocking can't be cushioned external force or vibration-inhibition effectively, usually can make precision component fault in the camera lens or impaired; severe patient causes camera lens to damage easily, and slight person also can influence image quality.In order to improve the shock-absorbing mechanism of camera lens, just there is the dealer to be provided between camera lens and camera body the design of installing cushion pad, as rubber blanket, foam or the like, give the impact of camera lens to slow down camera body.Yet the cushion pad of solid type is bearing under the excessive impact power still and vibrations or external force can be passed to camera lens, makes its buffering still limited with the protection effect, thereby still is not in the shock-absorbing of camera lens and the optimal design in the protection mechanism.

Summary of the invention

Existing camera product is quite ripe in the fixed form of camera lens; and some also is provided with the solid state buffer pad and carries out shock-absorbing and protection for camera lens; but the solid state buffer pad structurally still can't provide the most effective shock-absorbing and protection mechanism, thereby the utility model proposes a kind of camera lens module that best shock-absorbing and protection mechanism are provided.

According to the disclosed camera lens module of the utility model, it includes an image-forming assembly and a protection assembly, is applied to a digital imaging apparatus, as camera.Image-forming assembly includes a camera lens and a sensitive piece, and the protection assembly includes a housing and a plurality of elastic component.Enclosure interior has a chamber, is filled with a liquid in the chamber, and liquid is the damping fluid that possesses high coefficient of viscosity, as the damping ointment.Elastic component is arranged at the inwall of housing and is placed in chamber, and elastic component end common formation one outstanding territory, dead zone in chamber.The camera lens of image-forming assembly is placed in outstanding territory, dead zone, and is coated and be suspended in the chamber by liquid, with vibrations or the impact that is come from the outside by liquid and elastic component buffering.

Effect of the present utility model is; the camera lens of image-forming assembly be by liquid suspension in the protection assembly housing in; in case camera is clashed into or sharp pounding; the external force of the liquid of protection assembly and elastic component available buffer bump is also isolated vibrations, with the image-forming assembly that camera is provided excellent protection and shock-absorbing mechanism.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.
