Please consult Fig. 2 again; The cap structure 3 of optical devices 1 can at least partly be covered on the camera lens module 2; Cap structure 3 has operating space 30; And operating space 30 comprises a broken groove 301, and it can be arranged at the bottom surface of operating space 30 and be communicated with operating space 30, when second adjusting part 42 makes up with cap structure 3, to supply second to interfere drive mechanism 420 parts to pass brokenly groove 301.In addition, cap structure 3 also comprises extending column 31 and baffle plate 32, in present embodiment; Extending column 31 and baffle plate 32 can be extended towards the direction of camera lens module 2 by the bottom surface of operating space 30, and its bearing of trend is to be good perpendicular to the axial of camera lens module 2, in other words; The extending column 31 of present embodiment and baffle plate 32 can extend along the Z direction, and wherein the number of extending column 31 can be two, and it roughly is divided into brokenly two opposite ends of groove 301; And extending column 31 can be cylindrical structural, and it is perforation 4210 apertures of auxiliary fixing member 421 its extensions 4213 of corresponding matching second adjusting part 42 in fact, and the external diameter of the cylindrical structural of extending column 31 is in fact less than the internal diameter of the passage 433 of elastic parts 43; The shape of right extending column 31, number be not as limit; Number as for baffle plate 32 then can be three, and those baffle plates 32 are online always for good to be arranged at, yet should understand; The number of baffle plate 32 and size do not have yet the institute limit, visual demand is adjusted.

Please consult Fig. 2 again and cooperate Fig. 1; First adjusting part 41 of optical adjustment assembly 4 is arranged on the camera lens module 2; Second adjusting part 42 then can link to each other with cap structure 3 with elastic parts 43; When second adjusting part 42 and elastic parts 43 are desired with respect to 3 configurations of cap structure, passage 433 correspondences of elastic parts 43 are arranged in the extending column 31 of cap structure 3, extending column 31 can be placed in the passage 433 of elastic parts 43; 4210 of perforation as for auxiliary fixing member 421 its extensions 4213 that are arranged with the second interference drive mechanism 420 can be corresponding to the extending column 31 of cap structure 3; And be locked on the extending column 31 through the perforation 4210 that locked assembly 5 runs through extension 4213, come off on to utilize locked assembly 5 to resist to avoid second adjusting part 42, and limit the direction that second adjusting part 42 extends in extending column 31 through locked assembly 5 by cap structure 3 in the bottom surface of the extension 4213 of auxiliary fixing member 421; That is Z direction; The falling-threshold position, interfere this moment second drive mechanism 420 then can partly correspondingly pass cap structure 3 operating space 30 broken groove 301 and part is placed in the

operating space

30, and 4211 of the plates of auxiliary fixing member 421 can be resisted against on the baffle plate 32 of cap structure 3; Aperture and extending column 31 owing to perforation 4210 cooperatively interacts again; Therefore can know that extending column 31 can pass perforation 4210 in fact, and second adjusting part 42 is able to along the Z direction with respect to extending column 31 activities; In other words; Second adjusting part 42 is movably connected in cap structure 3, and second adjusting part 42 in fact can be movable in a predetermined distance d 0 in 30 bottom surfaces, operating space, that is along movable between the falling-threshold position of extending column 31 bearing of trends.

Please consult Fig. 1 again; Because elastic parts 43 is sheathed on the extending column 31 of cap structure 3; And the extension 4213 of auxiliary fixing member 421 is also with its perforation 4210 extending columns 31 corresponding to cap structure 3; Therefore after second adjusting part 42 disposes through locked assembly 5 and with respect to cap structure 3; Elastic parts 43 can be through auxiliary fixing member 421 the support of extension 4213 be arranged between the cap structure 3 and second adjusting part 42, wherein the first end 431 of elastic parts 43 contacts with cap structure 3 in fact, the second end 432 then can be contacted with the extension 4213 of auxiliary fixing member 421; And since extension 4213 structures in the form of slot of present embodiment be placed in the extension 4213 so the second end 432 of elastic parts 43 also can be considered.Should understand in addition, when second adjusting part 42 moved in predetermined distance d 0, elastic parts 43 can provide elasticity pushing and pressing strength in second adjusting part 42.

Please consult Fig. 3 again and cooperate Fig. 1, wherein Fig. 3 is the combination synoptic diagram of the present invention's optical devices shown in Figure 2.As shown in Figure 3; Camera lens module 2 can be carried on the pedestal 10 of optical devices 1; The cap structure 3 that is connected with second adjusting part 42 and elastic parts 43 then can at least partly be covered on the camera lens module 2; Wherein, second of second adjusting part 42 interferes drive mechanism 420 in fact corresponding to the first interference drive mechanism 410 that is arranged on first adjusting part 41 on the camera lens module 2, and in present embodiment; When optical devices 1 configuration is accomplished; Second of second adjusting part 42 interferes drive mechanism 420 in extending column 31 bearing of trends, that is the Z direction, the minor increment of falling-threshold position to pedestal 10 be d2; Wherein should apart from d2 be not more than in fact camera lens module 2 in the Z direction when pedestal 10 produces peak excursions; It is d1 that first of first adjusting part 41 is interfered the ultimate range of drive mechanism 410 to pedestal 10, in other words, and when 42 of second adjusting parts falling-threshold position in the Z direction; Its second interference drive mechanism 420 can interfere drive mechanism 410 contact with first of first adjusting part 41 really; Because the second interference drive mechanism 420 of present embodiment is a gear, it takes turns transverse tooth thickness T can cooperate the tooth pitch G that interferes the tooth pitch G of drive mechanism 410 and be slightly less than the first interference drive mechanism 410 in fact for first of toothrow again, and therefore second interferes drive mechanism 420 to be meshing with each other with the first interference drive mechanism 410.

Yet; Camera lens module 2 must be done adjustment slightly in being disposed at pedestal 10 last times possibility; And also possibly make camera lens module 2 produce displacement slightly in carrying or the use because of rocking with respect to pedestal 10; For example millimetre-sized displacement, for example, when camera lens module 2 when the Z direction upwards squints with respect to pedestal 10; First of first adjusting part 41 is interfered drive mechanism 410 will replace second of second adjusting part 42 and is interfered drive mechanism 420; Interfere drive mechanism 420 to be sheathed on the axial region 4212 of auxiliary fixing member 421 owing to second again, therefore second interferes the further auxiliary fixing member 421 that drives of drive mechanism 420 meetings to move on the whole, to be arranged at the elastic parts 43 between auxiliary fixing member 421 and the cap structure 3 through extension 4213 compressings; Making elastic parts 43 produce a reacting force interferes drive mechanism 420 to be resisted against first really with second and interferes drive mechanism 410 towards the pushing and pressing of camera lens module 2 directions; In other words, elastic parts 43 can be along with moving of camera lens module 2 elasticity push against second adjusting part 42 and in predetermined distance d 0 in, move, make second of second adjusting part 42 interfere drive mechanism 420 to be resisted against the first interference drive mechanism 410 towards the direction of camera lens module 2; In addition; Because the plate 4211 of the auxiliary fixing member 421 of second adjusting part 42 is resisted against the baffle plate 32 of cap structure 3, therefore when second adjusting part 42 moves in predetermined distance d 0 along with the displacement of camera lens module 2, can assist restriction second adjusting parts 42 in directions X through baffle plate 32; That is the moving of the axial direction of camera lens module 2, make its can be stably the activity in 0 along the Z direction in predetermined distance d; As for squinting towards pedestal 10 when camera lens module 2; That is be directed downwards when skew along Z; Because first of first adjusting part 41 interfered the ultimate range d1 of drive mechanism 410 to pedestal 10 to be not less than second adjusting part 42 in fact when the falling-threshold position of Z direction when it produced peak excursion; The minor increment of its second interference drive mechanism 420 to pedestal 10 is d2; Therefore first, second interferes drive mechanism 410,420 still can be engaged with each other, and hence one can see that, and no matter how camera lens module 2 moves on the Z direction; All can push against second adjusting part 42 through elastic parts 43 elasticity moves in a predetermined distance d 0; Make second to interfere drive mechanism 420 to replace and stably be engaged in the first interference drive mechanism 410 towards the direction of camera lens module 2, in other words, elastic parts 43 can provide a buffering adjusting and be unlikely to influence the engagement that contacts that the second interference drive mechanism 420 and first is interfered 410 of drive mechanisms.

Because cooperating in fact and be slightly less than first, the wheel transverse tooth thickness T of the second interference drive mechanism 420 interferes the tooth pitch G of drive mechanism 410 again; Therefore if camera lens module 2 has when squinting slightly in the Y direction, second interferes the gear teeth of drive mechanism 420 still can drop on first interferes 410 liang of adjacent wheel between cog of drive mechanism; In addition; Since first interfere drive mechanism 410 width W 1 in fact greater than second interfere drive mechanism 420 width W 2; Therefore if camera lens module 2 is when directions X produces displacement slightly; First interferes drive mechanism 410 still can contain second interferes drive mechanism 420, therefore can through first interfere drive mechanism 410 width W 1, width W 2, wheel transverse tooth thickness T that tooth pitch G and second interferes drive mechanism 420 assist and avoid second to interfere drive mechanism 420 with respect to 410 disengagings of the first interference drive mechanism.

Can know by above-mentioned explanation; Even if camera lens module 2 possibly produce millimetre-sized offset in X, Y, Z direction in the process that is configured in pedestal 10 or in carrying, use; Right its all can utilize and can keep the stable engagement that the second interference drive mechanism 420 and first is interfered 410 of drive mechanisms with respect to cap structure 3 movable second adjusting part, 42 collocation elastic partss 43; Therefore open the operating space 30 of cap structure 3 and when regulating the second interference drive mechanism 420 as the user; Just can interfere drive mechanism 420 to drive first through second and interfere drive mechanism 410 further to rotate first, second camera lens set collar 411,412 of first adjusting part 41, so that regulate the optical parametric of camera lens module 2.

Certainly; The present invention is not limited to above-mentioned enforcement aspect; For example, in some embodiment, the leaf spring of ㄑ font also capable of using replace in the foregoing description coil spring and as elastic parts; Wherein the first end of leaf spring is capable of using is fixed on the cap structure like locked assembly etc.; The second end then can be connected in the extension of the auxiliary fixing member of second adjusting part, and the physical characteristics elasticity of its same leaf spring capable of using pushes against second adjusting part and in a preset distance, moves, and makes second to interfere drive mechanism to replace and keep with first of first adjusting part and interfere the stable engagement of drive mechanism towards the camera lens module direction.And the interference drive mechanism of first in the above embodiment of the present invention and the second interference drive mechanism are that example is explained with toothrow and gear respectively; So should understand; In some embodiment, also can the helical structure that toothrow and gear change cooperatively interacting be substituted, change speech; Such as any can all can be applicable to the present invention and interfere drive mechanism through interfering with each other the structure of reaching the transmission purpose as first, second.

In addition; Embodiments of the invention are disposed at the auxiliary fixing member of second adjusting part with two elastic partss two relative terminals are that example describes, and this configuration mode helps stablizing the activity along the Z direction in preset distance of second adjusting part, so should understand; In some embodiment; Also optionally directly utilize elastic parts to connect second and interfere drive mechanism and cap structure and the use of omitting the auxiliary fixing member, and the number of elastic parts do not exceed with two, for example; In some embodiment; Also can use single leaf spring as elastic parts, and first, second end of this elastic parts is individually fixed in the wherein terminal of cap structure and auxiliary fixing member, its same leaf spring capable of using provides a regulating effect and is unlikely to influence enforcement of the present invention; Certainly, in some embodiment, the number of also visual increase in demand elastic parts is with the effect of strengthening regulating.Hence one can see that; The real nothing of elastic parts of the present invention and number thereof and configuration mode institute limits; Any have elasticity; And configurable between second adjusting part and cap structure so that the buffering regulating effect to be provided, push against second adjusting part and make second to interfere drive mechanism can stably be engaged in first to interfere drive mechanism, all can be applicable to the present invention with mobile elasticity along with camera lens module.

In sum; The main elastic parts that is disposed between second adjusting part and the cap structure capable of using of optical adjustment assembly of the present invention provides regulating effect; And through first interfere drive mechanism the mutual collocation of width, width that tooth pitch and second is interfered drive mechanism, wheel transverse tooth thickness assist and avoid first, second interference drive mechanism relative to each other to break away from; Even if be in configuration, possibly produce displacement slightly when using with the camera lens module of optical devices of the present invention; It still can second adjusting part through movable cooperates the physical characteristics elasticity of elastic parts to push against second adjusting part in a preset distance, to move; Make second to interfere drive mechanism to replace and stably interfere drive mechanism to keep engagement with first towards the direction of camera lens module; So just need not to use the fixed camera lens module of prior art; Relatively also can reduce the assembly accuracy requirement of camera lens module, thereby reduce the cost of optical devices, and can avoid existing fixed camera lens module because of carrying on the back the burnt fixing defective that influences projected picture.

In addition; When optical adjustment component application of the present invention in more small-sized optical devices; For example: during ultrashort out-of-focus projection machine; Because the space of its cap structure is limited; Be second adjusting part that cooperatively interacts with first adjusting part to set up through the present invention, and mat second adjusting part second interfere drive mechanism to be interfered to drive first of first adjusting part that is arranged on the camera lens module to interfere drive mechanism, with the design of indirect regulation camera lens module optical parametric; Remove and to avoid corresponding first adjusting part of perforation being set and the problem of directly regulating the optical devices overall volume increase that optical parametric institute possibly cause, also can keep the optical devices integral aesthetic property and make optical devices be able to meet the miniaturization demand through first adjusting part in the cap structure.

Moreover; Because structure of the present invention is simple and elastic parts with low cost; Be waiting the technology of optical parametric compared to existing focusing through the motor transmission, the present invention also can reduce the whole cost of optical devices through the expense of reduction part, and simplifies the complexity of its configuration.The present invention is with the second interference drive mechanism of second adjusting part of manual adjustments optical adjustment assembly again; And interfere drive mechanism to drive first through second and interfere drive mechanism to rotate the optical parametric that first, second camera lens set collar is adjusted camera lens module; Except that need not considering the complicated mechanical configuration; In the time of also can avoiding through motor transmission adjusting optical parametric, because of machinery inertial causes being difficult to the accurately problem of adjusting.Because above-mentioned characteristic and advantage are all prior art can't be obtained, are to have industrial value with optical devices of the present invention and optical adjustment assembly thereof, and meet each item and apply for a patent and require and condition, files an application in the whence in accordance with the law.

Can appoint by those skilled in the art even if the present invention has been described in detail by the foregoing description and to execute the craftsman and think and do and modify as all, still all not break away from as attaching the protection domain of claims.
