Embodiment
As shown in figures 3-8, the invention provides a kind of camera module base, the lens barrel 12 comprising the uncovered enclosed seat in bottom 11 and be located on enclosed seat 11; Enclosed seat 11 inside has the first accommodation space 11a that be communicated with uncovered with bottom; The hollow space of lens barrel 12 inside is communicated with the first accommodation space 11a, and the cross-sectional area of lens barrel 12 interior hollow section is less than the rank street area of the inner first accommodation space 11a of enclosed seat 11; Lens barrel 12 inwall has one for from edge filter 3 being held in the holding section 121 in the second accommodation space 12a; The hollow space of lens barrel 12 inside is divided into two parts by holding section 121, and the part wherein near the first accommodation space 11a is the second accommodation space 12a.
Be the 3rd accommodation space 12b away from that part of the first accommodation space 11a in the present embodiment, camera lens 2 is positioned at the 3rd accommodation space 12b, and during focusing, camera lens 2 12b in the 3rd accommodation space is lower mobile in the vertical direction; Second accommodation space 12a is for placing filter 3, holding section 121 is arranged along lens barrel 12 inwall for one week, move to the direction at camera lens 2 place for stoping filter 3 from marginal portion, camera lens 2 is positioned at the first accommodation space, light enters in filter 3 from the space can not blocked by holding section 121 through part broad in the middle after camera lens 2 reflects, finally imaging on sensitive chip 4; Second accommodation space 12a is positioned at bottom lens barrel 12, original idle, utilizes now this segment space to place filter, can reduce the height of camera module base.
The concrete shape of holding section 121 can be the annular of hollow, also can be at least three claws arranged for a week along camera lens inwall, in a word, as long as meet middle part hollow out, do not shut out the light and enter on filter, and filter 3 can be stoped to move to the direction near camera lens 2 from the axis of lens barrel 12.
General filter thickness is 0.3mm, inside lens barrel filter being placed on base, utilizes the idle space of lens barrel inside to place filter, enclosed seat can be reduced 0.3mm, thus by module height reduction 0.3mm; Tradition camera module base places filter in enclosed seat, and in lens barrel, in this programme, place filter, lens barrel inside is mainly used in accommodating camera lens, the circuit of enclosed seat on accommodating sensitive chip and flexible circuit board, and camera lens side size is much smaller than the size of sensitive chip and flexible circuitry on-board circuitry, therefore enclosed seat cross-sectional area is greater than lens barrel cross-sectional area, therefore invent the area that the filter area used in the scheme provided is less than filter in traditional base, save filter cost; May be used for COB technique, but parsing power can not be reduced, owing to having placement filter inside mirror bucket, in focussing process, the trifling induction chip surface of can not directly dropping of generation, but drop on filter, can not direct imaging, therefore can not affect parsing power; Overcome the defect of above two kinds of traditional design, both effectively can reduce the height of camera module and electronic equipment, can save filter cost again, and can not produce stain cause parsing power to reduce on sensitive chip, image quality is higher.
Embodiment one as such scheme:
As shown in Figure 3, Figure 4, ringwise, and holding section 121 periphery wall is fixed on lens barrel 12 inwall in holding section 121.Structure is simple, be easy to processing.
Embodiment two as such scheme:
As shown in Figure 5, Figure 6, holding section 121 comprises at least three claws, and claw is arranged along lens barrel 12 inwall for one week.Holding section area occupied is less, and be conducive to light like this and be fully irradiated on filter, can give full play to the function of filter self, image quality is higher.
On the basis of above-described embodiment:
As shown in Fig. 4, Fig. 6, in order to improve the stability of camera module structure, bottom holding section, 121a is in the same plane for the part contacting filter 3.Filter surfaces being flat shape, the area that holding section contacts with it is larger, and stability is higher, therefore the part contacted with filter bottom holding section all at grade, when coordinating with the contact-making surface of filter, can be just that contact area is maximum, stability be the highest.
As shown in Figure 7, Figure 8, the present invention also provides a kind of camera module, at least comprises base 1, camera lens 2, filter 3, induction chip 4 and flexible circuit board 5, and camera lens 2, filter 3 and induction chip 4 are all located in base 1;
Base 1 is the camera module base of above-mentioned any embodiment;
Induction chip 4 is arranged in the first accommodation space 11a;
Filter 3 is arranged in the second accommodation space 12a of camera module base;
In two parts that the hollow space of lens barrel 12 inside is divided into by the holding section 121 in camera module base, the part wherein away from the first accommodation space 11a is the 3rd accommodation space 12b, and camera lens 2 is located in the 3rd accommodation space 12b;
Flexible circuit board 5 is connected with the bottom opening end of enclosed seat in camera module base 11, and is encapsulated in the first accommodation space 11a by induction chip 4.
As shown in Figure 7, the present invention also provides a kind of electronic equipment, the camera module comprising electronic equipment mainboard and be connected with electronic equipment mainboard:
Camera module is the camera module of above-mentioned any embodiment;
Camera module also comprises at least one connector 6, and connector 6 connects the flexible circuit board 5 in electronic equipment mainboard and camera module.
The camera module that the embodiment of the present invention provides and electronic equipment, owing to have employed thinner or perhaps that short transverse size is less camera module base, and then reduce the height of camera module and electronic equipment, thus be conducive to camera module and electronic equipment to lightening future development.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
