Abstract
The invention discloses a camera shooting module which comprises a lens assembly, a motor assembly and a substrate assembly. The lens assembly comprises a lens piece and a lens cone containing the lens piece. The motor assembly comprises a motor and a support for supporting the motor. The lens assembly is arranged inside the motor. The substrate assembly comprises a light-sensitive chip and a circuit board. The light-sensitive chip and the circuit board are packaged together. The upper surface of the support is provided with at least three supporting portions. One plane is determined by the supporting portions, and the upper surfaces of all the supporting portions are located on the plane. According to the camera shooting module, the image quality is free of dark corner and better in resolution consistency, and the purpose of improving the image quality of the camera shooting module is achieved.
Description
Technical field
The present invention relates to optical pick-up apparatus, especially relate to a kind of camera module.
Background technology
Camera module is widely used in mobile phone, computer, the vehicle-mounted camera of automobile industry, the first-class field of monitoring camera of security protection industry.Conventional camera module is made up of parts such as lens assembly, motor sub-assembly and board units, and wherein, motor sub-assembly comprises motor and the support for supporting motor, and lens assembly is mounted on support by motor.High pixel, high resolution are the important development directions of camera module, so very high to the planarity requirements of wherein each parts, if flatness does not reach, the problem of a series of image quality effect aspects such as dark angle can occur.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition carries out improving to prior art and improves, and provides a kind of camera module, by improving the surface planarity of support, to reach the object improving camera module image quality effect.For this reason, the present invention takes following technical scheme.
A kind of camera module, comprise lens assembly, motor sub-assembly and board unit, described lens assembly comprises eyeglass and holds the lens barrel of eyeglass, described motor sub-assembly comprises motor and the support for supporting described motor, described lens assembly is arranged on described motor internal, described board unit comprises sensitive chip and wiring board, described sensitive chip and described wiring board are packaged together, and: described rack upper surface is provided with at least 3 support portions, a plane is determined in described support portion, and the upper surface of all described support portions is all positioned in this plane.
As the preferred technical scheme of one, the number of described support portion is 3, and three support portions are placed on any both sides of support, is enough to support motor.
As the preferred technical scheme of one, the top of described support portion is identical with the distance between frame bottom, and the determined plane in described support portion is parallel to the lower surface of described support.
As the preferred technical scheme of one, described support portion is rectangular parallelepiped, right cylinder or other arbitrary shapes.
Owing to adopting technique scheme, camera module provided by the invention, support arranges at least 3 support portions, a plane is determined in support portion, the upper surface of all support portions is all in the same plane, motor is mounted on support portion, the plane of carrying is determined by limited several support portions, the flatness of this plane is higher, so the depth of parallelism of lens plane and described sensitive chip is than improve of the prior art, therefore by camera lens arrive sensitive chip surface light evenly, image quality is without dark angle, resolving power consistance is higher, reach the object improving camera module image quality effect.Meanwhile, when support height is improper in actual applications, only can revise the height of support portion, more simple efficient; Measure the flatness that rack surface flatness also only needs to measure support portion, easy to operate and accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of camera module of the present invention.
Fig. 2 is the structural representation of the support of camera module of the present invention.
In figure, lens assembly 1, motor 21, support 22, support portion 221, sensitive chip 31, wiring board 32.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to shown in Fig. 1, present invention is disclosed a kind of camera module, comprise lens assembly 1, motor sub-assembly and board unit, lens assembly 1 comprises eyeglass and holds the lens barrel of eyeglass, motor sub-assembly comprises motor 21 and the support 22 for supporting motor 21, it is inner that lens assembly 1 is arranged on motor 21, board unit comprises sensitive chip 31 and wiring board 32, sensitive chip 31 and wiring board 32 are packaged together, and: support 22 upper surface is provided with 3 support portions 221, a plane is determined in support portion 221, and the upper surface of 3 support portions 221 is all positioned in this plane.
It is inner that lens assembly 1 is arranged on motor 21, motor 21 is mounted in the determined plane in support portion 221, this plane only comprises the upper surface of 3 support portions 221, the flatness of its flatness plane more whole than prior art medium-height trestle is high, so the depth of parallelism of lens plane and sensitive chip 31 is high, therefore better by the light uniformity on camera lens arrival sensitive chip 31 surface, thus for the camera module of high pixel, the light of each pixel is more even, difference is little, image quality is better without dark angle, resolving power consistance, and image quality effect comparatively prior art improves.
Because the number of support portion 221 is more, the flatness of the determined plane in support portion 221 is more difficult to be controlled in higher standard, but motor 21 needs stable to be mounted on support 22, need support portion 221 The more the better, so the number of the support portion 221 of the present embodiment is 3.
The top of support portion 221 is identical with the distance between bottom support 22, and the determined plane in support portion 221 is parallel to the lower surface of support 22.
The present embodiment does not limit the shape of support portion 221, and its shape preferably can be designed to rectangular parallelepiped, right cylinder or other arbitrary shapes, and the present embodiment is preferably right cylinder.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
