Please refer to the drawing 1, the camera module 10 of the utility model embodiment comprises housing 12, lens unit 14 and marmem line 18.Lens unit 14 is contained in housing 12.Marmem line 18 connection lens unit 14 and housing 12.Marmem line 18 realizes shrinking or stretching to drive lens unit 14 to move along optical axis by energising or power-off.
In the camera module 10 of the utility model embodiment, because camera module 10 adopts marmem line 18 to move to drive lens unit 14, therefore, camera module 10 is without the need to voice coil motor, and structure is simple, and the technological process of production simplifies, save certain space, volume reduces.
In the present embodiment, camera module 10 comprises back up pad 16, and this back up pad 16 to be contained in housing 12 and to be fixed on the bottom of lens unit 14, and marmem line 18 connects housing 12 and back up pad 16.
So, marmem line 18 is by pulling back up pad 16 thus driving lens unit 14 along axis movement.
Particularly, marmem line 18 has recoverable force ability.Marmem line 18 has two kinds of phases: high-temperature-phase austenite phase, low-temperature phase martensitic phase.Marmem line 18 original state is extended state, by making its temperature raise to marmem line 18 energising, marmem line 18 like this undergoes phase transition as austenite by martensite, contraction in length, thus drives back up pad 16 and lens unit 14 to move along optical axis direction.
When 18 power-off of marmem line, temperature reduces, and marmem line 18 undergoes phase transition as martensite by austenite, and the length of marmem line 18 reverts to original extended state, and back up pad 16 and lens unit 14 get back to initial position.
In the present embodiment, housing 12 is by insulating material, and as plastic cement is made, its inside surface is provided with two electric contact mats 20, and the two ends of marmem line 18 are connected with two electric contact mats 20 respectively.
So, be energized to marmem line 18 by two electric contact mats 20.
In the present embodiment, the inside of housing 12 is embedded with electric-conductor, and electric-conductor is electrically connected with electric contact mat 20 and the external circuit board.
So, be energized to marmem line 18 by circuit board, electric-conductor and electric contact mat 20.
Particularly, electric-conductor and housing 12 obtain by embedding jetting formation process, and electric-conductor can be plain conductor or metallic conduction sheet.
In the present embodiment, housing 12 is that hollow is rectangular-shaped, and comprise roof 120, diapire 122, relative the first side wall 124 and the second sidewall 126, and the 3rd relative sidewall (figure do not mark) and the 4th sidewall (scheming not mark), roof 120, diapire 122, the first side wall 124, second sidewall 126, the 3rd sidewall and the 4th sidewall are formed with receiving space 12b, lens unit 14 is housed in this receiving space 12b, and the first side wall 124 and the second sidewall 126 are respectively equipped with electric contact mat 20.
So, housing 12 is formed with receiving space 12b to accommodate lens unit 14 and back up pad 16.
In the present embodiment, back up pad 16 is in tabular, and back up pad 16 is fixed with director element 22, the periphery wall of director element 22 offers groove 22a, marmem line 18 is arranged in groove 22a.Particularly, marmem line 18 is in the shape of the letter V and is arranged in housing 12.
So, by being stuck in the marmem line 18 of groove 22a, marmem line 18 moves along lens unit 14 optical axis direction by pulling director element 22, thus drives back up pad 16 and lens unit 14 to move along optical axis direction.
In the present embodiment, director element 22 comprises first surface 220 and the second surface 222 opposing with first surface 220, and director element 22 offers the directed cavity 224 running through first surface 220 and second surface 222.First surface 220 is towards the inside surface of housing 12, and second surface 222 connects back up pad 16.
Camera module 10 comprises guide pillar 24, and guide pillar 24 is partly contained in directed cavity 224.Guide pillar 24 comprises the 3rd surface 240 and the 4th opposing surface, surface the 242, three 240 is connected with roof 120 with the 3rd surface 240, and the 4th surface 242 keeps spacing with back up pad 16.Guide pillar 24 is arranged with flexible member 26, as spring.One end of flexible member 26 contacts with roof 120, and the other end of flexible member 26 contacts with first surface 220.
In present embodiment, one end of flexible member 26 is fixed on roof 120, and the other end of flexible member 26 is fixed on the first surface 220 of director element 22.Be appreciated that in other embodiments, one end of flexible member 26 also can not be fixedly connected with roof 120, and the other end of flexible member 26 also can not be fixedly connected with first surface 220.

So, marmem line 18 is energized post shrinkage, and the stressed drive back up pad 16 of director element 22 and lens unit 14 together move upward, and now the 4th surface 242 of guide pillar 24 reduces with the distance of back up pad 16, and flexible member 26 is compressed.During 18 power-off of marmem line, marmem line 18 restores, and lens unit 14 returns to original position under the elastic force effect of flexible member 26, and then realizes focus function.
Particularly, director element 22 is cylindrical shape, and the second surface 222 of director element 22 is fixedly mounted on the side of back up pad 16.Guide pillar 24 is ganoid right cylinder, and the bottom of guide pillar 24 is plugged in the directed cavity 224 of director element 22, and the 4th surface 242 of guide pillar 24 does not contact with back up pad 16 and reserved certain height space.
In the present embodiment, the lens barrel that lens unit 14 comprises hollow cylindrical and the lens set be contained in lens barrel, roof 120 offers the first light hole 12c relative with lens set, and diapire 122 offers the second light hole 12d relative with lens set.
In addition, the middle part of back up pad 16 offers the three light hole 16a relative with lens set, and back up pad 16 is arranged on the bottom of housing 12 separably.
In the present embodiment, back up pad 16 and lens barrel are formed in one structure, common bearing lens group.
So, reduce the assembly process of camera module 10, improve the production efficiency of camera module 10.
Certainly, in other embodiments, back up pad 16 and camera lens 140 can be not limited to integrated formed structure, can also adopt other connected mode.
The camera head of the utility model embodiment comprises the camera module 10 of above-mentioned arbitrary embodiment.
In the camera head of present embodiment, owing to adopting marmem line 18 to drive lens unit 14 to move, camera head is without the need to voice coil motor, and structure is simple, and the technological process of production simplifies, and saves certain space, and volume reduces.
Particularly, camera head can for digital camera, digital camera, mobile phone, panel computer, monitor or other there is the electronic installation of camera function.
