The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the light fixture automatic focusing structure of the present embodiment comprises lens 3, illuminator 4, actuating unit 1 and the focusing component that relative lens 3 works move around under actuating unit drives, wherein, lens 3 are fixed on lamp holder 10 heads, focusing component is positioned at the rear of lamp holder 10, and 4 of illuminators are fixedly mounted on the focusing component.
The actuating unit 1 of the present embodiment adopts motor, and motor is installed on the actuating unit seat 9.Front end at actuating unit seat 9 is fixed with sleeve 8, respectively is provided with one along the pilot hole 81 of sleeve axial distribution in the front end two opposite sides of sleeve 8.Adjusting part matches with actuating unit 1 and sleeve 8, and particularly, adjusting part comprises illuminator seat 5 and threaded column 6, and illuminator 4 is installed on the illuminator seat 5.Head edge at illuminator seat 5 is provided with two lugs that are oppositely arranged 51, lug 51 is fastened in the corresponding cage guiding hole 81, form internal thread hole 52 in the bottom of illuminator seat 5, the front end of threaded column 6 is threaded in this internal thread hole 52, and the rear end of threaded column 6 is connected with actuating unit output shaft 7.In the present embodiment, be provided with " ten " font projection 71 at actuating unit output shaft 7 front ends, be provided with " ten " font groove 61 that matches with this " ten " font projection 71 in the rear end of threaded column 6, adopt this concavo-convex " ten " font fit structure, not only structure is comparatively simple, and cooperates also comparatively firm.In addition, have installing hole at the sidewall of actuating unit seat 9, press button 2 is installed in installing hole, this press button 2 is used for starting rotating and reverse of actuating unit 1.
Especially, the present embodiment also is equipped with the single-chip microcomputer (not shown) that control actuating unit 1 rotates and reverse in actuating unit seat 9 inside, and the press button 2 that startup actuating unit 1 rotates and reverse is electrically connected with this single-chip microcomputer.As long as single-chip microcomputer Stroke Control program reasonable in design, can realize the electrodeless focusing of light fixture with above-mentioned press button 2, and focusing component comes and goes mobile haul distance and comes and goes mobile whole journey time and all can preset in SCM program.
The operation principle of the light fixture automatic focusing structure that the present embodiment provides is as follows: suppose that at first illuminator 4 is in the maximum distance apart away from lens 3, according to single-chip microcomputer Stroke Control program, press the button behind the switch 2 and unclamp, actuating unit 1 forward, actuating unit output shaft 7 outputting powers are to threaded column 6 and drive threaded column 6 rotations, threaded column 6 further outputting powers are to illuminator seat 5, because illuminator seat 5 is fastened in the pilot hole 81 of sleeve 8 by its lug 51, thereby, rotation along with threaded column 6, illuminator seat 5 can only move forward along the pilot hole 81 of sleeve 8, thereby furthers distance between illuminator 4 and the lens 3.If in this focusing process, no longer press button 2 is done any operation, then illuminator 4 continues near lens 3, until the distance between illuminator 4 and the lens 3 is when reaching the minimum range that single-chip microcomputer Stroke Control program sets, single-chip microcomputer output control signal makes actuating unit 1 stall to actuating unit 1; If in this focusing process, again press the button switch 2, then according to the single-chip microcomputer Stroke Control program of setting, single-chip microcomputer output control signal is to actuating unit 1, and actuating unit 1 stall is just illuminator seat 5 and illuminator 4 stop to move to lens 3 directions.After this, again press the button switch 2, single-chip microcomputer output control signal is to actuating unit 1, actuating unit 1 continues forward, illuminator seat 5 and illuminator 4 continue to move to lens 3 directions, until between illuminator 4 and the lens 3 reach the minimum range that single-chip microcomputer Stroke Control program sets the time, actuating unit 1 stall.As seen, it is comparatively convenient that this automatic focusing process not only operates, and intelligent degree is better.In this automatic focusing structure, be designed to 3 seconds from the whole journey time that the maximum position away from lens 3 moves near the minimum position place of lens 3 incessantly for illuminator 4.Certainly, as required, the trip time also can be adjusted accordingly.
Be under the state of minimum range between illuminator 4 and lens 3, press the button switch 2 and unclamp, actuating unit 1 begins counter-rotating, and actuating unit 1 drives illuminator 4 beginnings and begins the focusing process away from lens 3.Similarly, under the driving of actuating unit 1, illuminator seat 5 can only be mobile backward along the pilot hole 81 of sleeve, if in this moving process, press button 2 is not done any operation, then illuminator 4 continues away from lens 3, until the distance between illuminator 4 and the lens 3 is when reaching the ultimate range that SCM program sets, single-chip microcomputer output control signal makes actuating unit 1 stall to actuating unit 1.Correspondingly, the time of this whole focusing stroke also is designed to 3 seconds.In this focusing process, the automatic focusing process the when course of action that again presses the button switch 2 back focusing assemblies equally can be with reference to above-mentioned actuating unit 1 forward.
Extremely shown in Figure 6 such as Fig. 3, flashlight in the present embodiment has been used automatic focusing structure illustrated in figures 1 and 2, this flashlight comprises lamp holder 10, lamp cylinder 11 and tail-hood 12, described lens 3 are installed in lamp holder 10 front ends, the front end of described sleeve 8 is threaded mutually with lamp holder 10 rear ends, the rear end of described actuating unit seat 9 and lamp cylinder 11 front ends form and are tightly connected, and tail-hood 12 is threaded mutually with lamp cylinder 11 rear ends.Lamp cylinder 11 inside are provided with battery 18, in the front end inside of lamp cylinder 11 the first limiting cylinder 16 is installed, the afterbody of actuating unit 1 is connected with battery 18 after passing this first limiting cylinder 16, and the first limiting cylinder 16 can be spacing in lamp cylinder 11 preferably with actuating unit 1.In addition, the second limiting cylinder 17 is installed in the inside of actuating unit seat 9, the head of actuating unit 1 is to link to each other with threaded column 6 after actuating unit output shaft 7 passes this second limiting cylinder 17.In order to make this flashlight possess fire resistance characteristic, the flashlight of the present embodiment is provided with the first water proof ring 13 in the threaded connection place of sleeve 8 and lamp holder 10, is provided with the second water proof ring 14 in the threaded connection place of lamp cylinder 11 and tail-hood 12.
In addition, this flashlight also is equipped with the power switch 15 of energy opening and closing actuating unit power supply and luminophor power at the rear end face of tail-hood 12.Press this power switch 15, illuminator 4 is lit, and simultaneously, actuating unit 1 and press button 2 are in treats duty, and the user can realize by pressing press button 2 the automatic focusing process of flashlight, and the process of specifically focusing as above length has a detailed description.In the focusing process, as long as again press this power switch 15, illuminator 4 is extinguished, and simultaneously, actuating unit 1 stops operating, and press button 2 is also entirely ineffective.
