Embodiment
Below in conjunction with specific embodiment and accompanying drawing, camera module is described in detail, so that it is clearer.But the technical scheme of camera module can realize in many different forms, be not limited to embodiment described herein.On the contrary, providing the object of these embodiment is to make to the disclosure of camera module more thoroughly comprehensively.
Refer to Fig. 1 to Fig. 3, in embodiment mono-, camera module 10 comprises lens assembly 11, driving mechanism 12, web member 13 and support 14.
Lens assembly 11 comprises lens barrel 110 and is built in the optical element 112 of lens barrel 110.Driving mechanism 12 is installed on support 14, and web member 13 is contained in driving mechanism 12 movably, and web member 13 offers a through hole 130, and lens assembly 11 is embedded at through hole 130.In the present embodiment, through hole 130 and lens barrel 110 concentric settings.
Web member 13 inwalls offer detent 132 away from a side of support 14, lens barrel 110 outer walls extend to be provided with locates bead 111, location bead 111 is positioned over detent 132, and bonding with detent 132, so that web member 13 is fixedly connected with lens barrel 110, driving mechanism 12 drives web member 13 to drive lens assembly 11 to move along the central axial direction of lens barrel 110.
In the present embodiment, driving mechanism 12 comprises the magnet frame 120 and the shell 122 that are provided with magnet, the coated magnet frame 120 of shell 122, and web member 13 is arranged with coil.Shell 122 shields, and the magnetic field of avoiding driving mechanism 12 to produce in the time of work is subject to ectocine.
Magnet frame 120 is sticky is located at support 14, specifically can be connected in support 14 by a glue, and web member 13 is arranged in magnet frame 120 movably, as magnet frame 120 arranges shell fragment, web member 13 is held by shell fragment elasticity.In the time of the coil electricity of web member 13, the magnetic fields generation magnetic force of the magnetic field that coil produces and the magnet of magnet frame 120, this magnetically-actuated web member 13 drives lens assembly 11 to move along the central axial direction of lens barrel 110.
So, adopt magnet and coil effect to produce magnetic force, web member 13 is moved, because web member 13 is fixedly connected with lens barrel 110 along the central axial direction of lens barrel 110, therefore web member 13 can drive lens assembly 11 to move along the central axial direction of lens barrel 110 in the lump, and then realizes the object of focusing.Certainly, in other embodiments, driving mechanism 12 also can adopt other structures, can realize the object that drives web member 13 to drive lens assembly 11 to move along the central axial direction of lens barrel 110.
In the present embodiment, camera module 10 comprises image sensor 15 and circuit board 16, support 14 hollow settings, support 14 one end are connected with driving mechanism 12, the other end is sticky is located at circuit board 16, and image sensor 15 is arranged at the side of circuit board 16 towards lens assembly 11, and just to lens assembly 11.In the present embodiment, support 14 one end are connected with magnet frame 120 by a glue, and the other end is connected with circuit board 16 by a glue.
In use, light reaches in the image sensor 15 of circuit board 16 through pre-imaging object reflection lens assembly 11, and then forms image.According to distances different between pre-imaging object and camera module, can drive lens assembly 11 to move so that object is focused at camera model along the central axial direction of lens barrel 110 by driving mechanism 12, imaging clearly, the imaging effect of guarantee camera model.
In the present embodiment, in order to improve detent 132 and location bead 111 adhesive effects, location bead 111 has been offered a glue breach 1110 towards a side of detent 132.So, lens assembly 11 is embedded to the through hole 130 of web member 13, until location bead 111 is positioned over detent 132, now glue is clicked and entered in a glue breach 1110, thereby detent 132 is bonding with location bead 111, so that lens assembly 11 is fixedly arranged on web member 13, good positioning effect.Glue can adopt hot-setting adhesive.Be appreciated that a glue breach 1110 is nonessential, as directly between detent 132 and location bead 111 by modes such as glue are bonding, can realize and locate bead 111 and the bonding object of detent 132.
Further, some glue breach 1110 can run through location bead 111.So, the glue of clicking and entering in a glue breach 1110 can contact with the sidewall of detent 132 and bottom surface, increases bond area, further improves adhesive effect.Certainly, some glue breach 1110 also can not run through location bead 111, can realize location bead 111 object bonding with detent 132.
In the present embodiment, the degree of depth of detent 132 is greater than the height of locating bead 111.So, the outer wall of guaranteeing to locate bead 111 is all bonding with detent 132, ensures adhesive effect, also meets the topology requirement of camera module 10 simultaneously.
In the present embodiment, detent 132 is circular, and location bead 111 is circular arc.Because camera module 10 is generally cylindrical shape, lens assembly 11 and driving mechanism 12 are also generally cylindrical shape, therefore adopt circular detent 132, the location bead 111 of circular arc, with with the structure matching of camera module 10, and detent 132 also matches with the shape of location bead 111, and assembling effect is good.Certainly,, according to the camera module 10 of different institutions, the shape of detent 132 and location bead 111 also can be other.
Above-mentioned camera module 10, in assembling process, driving mechanism 12 is installed on support 14, web member 13 is contained in driving mechanism 12 movably, lens assembly 11 is embedded at the through hole 130 of web member 13, now the location bead 111 of lens barrel 110 is positioned over the detent 132 of web member 13, and location bead 111 is bonding with detent 132, thereby web member 13 is fixedly connected with lens barrel 110, so that driving mechanism 12 drives web member 13 to drive lens assembly 11 to move along the central axial direction of lens barrel 110, realize the object of focusing.So, detent 132 and location bead 111 play location fixed installation effect, without the test of focusing separately, and assembling good positioning effect, assembling process is easy; And avoid adopting screw connection structure in the time screwing togather, may produce chip and drop in image sensor 15, affect the problem of image quality.
Refer in the embodiment mono-of Fig. 1 to Fig. 3, the quantity of location bead 111 is three, refers in the embodiment bis-of Fig. 4, and the quantity of location bead 111 is two.The quantity of location bead 111 is arranged to at least two, and spacing between adjacent positioned bead 111 equates.So, improve on the one hand the contact area of location bead 111 with detent 132, ensure that on the other hand lens barrel 110 and web member 13 are evenly bonding, in the time that web member 13 drives lens assembly 11 to move, lens barrel 110 is stressed evenly, prevents lens barrel 110 certain part and occurs to become flexible and impact focusing effect.Certainly, location bead 111 also can be other quantity, can realize location bead 111 object bonding with detent 132.
Refer in the embodiment tri-of Fig. 5 and Fig. 6, embodiment tri-is only with the difference of embodiment mono-: a glue groove 1320 has been offered in the bottom surface of detent 132, and some glue groove 1320 is just to a glue breach 1110.So, in glue meeting inlet point glue breach 1110 and some glue groove 1320, the further bond area of increase and detent 132, effectively prevents that lens assembly 11 and web member 13 from use occurring loosening, improves the reliability of assembling.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
