Cosmetic lens device in automobile
Technical field
The present invention relates to technical field of automotive trim, particularly relate to cosmetic lens device in a kind of automobile.
Background technology
Current, in automobile, install in automobile lens device of making up has been configure in a very general car.Passenger is not when needing to make up lens device in use automobile, and in automobile, cosmetic lens device normally shelters from cover plate.In prior art, in automobile, cosmetic lens device is arranged in automobile by microscope base, and cover plate is hinged on microscope base to realize cover plate relative to lens device rotation of making up in automobile.Wherein, microscope base is provided with jump ring, and cover plate is connected by rotating shaft with microscope base, and rotating shaft is connected in jump ring; Jump ring is a standard room in auto trade, and with the part of jump ring clamping and incomplete circumference can be locked in a state for cover plate after rotation in rotating shaft.On the one hand, because current rotating shaft mostly is Plastic Parts, rotating shaft after this multiple use, in rotating shaft, incomplete circumferential part branch becomes the circumference that diameter reduces, namely rotating shaft cannot realize latch functions after rotating relative to jump ring, so cover plate just cannot keep quiescence relative to microscope base after turning, and that is, in automobile of the prior art, the service life of cosmetic lens device connection structure is partially short; On the other hand, due to cover plate relative to the rotation of microscope base be by rotating shaft hold out in spite of difficulties out jump ring constraint realize, namely in rotating shaft, incomplete circumferential section struts jump ring expansion, and it is comparatively large that passenger in use needs to overcome the application force that jump ring opens, and then has influence on the traveling comfort that passenger uses.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of long service life, and comfort is better and automatically can connect light fixture when cover plate is opened with lens device of making up in the automobile thrown light on to eyeglass.
Technical solution of the present invention is, there is provided cosmetic lens device in a kind of automobile with following structure: comprise the microscope base for installing eyeglass, cover plate, cover plate is connected on microscope base by two axis of rotation, the both sides of cover plate are respectively equipped with the first through hole for accommodating two rotating shafts, the outer end of at least one rotating shaft is provided with annular boss, the inner end surface of annular boss is provided with axially extended arc convex, and rotating shaft is provided with axially extended guidepost away from annular boss one end, microscope base is provided with the pilot hole for guidepost sliding block joint; The outer face of the first described through hole is provided with the arc groove matched with arc convex; Described microscope base is provided with the second through hole moved axially for annular boss in rotating shaft, and rotating shaft periphery wall is provided with for first plane spacing with microscope base circumference, and microscope base is provided with the second plane for matching with the first plane; Described rotating shaft is provided with the strip shape through hole of radial through rotating shaft along shaft axis direction, described microscope base is provided with U-shaped jump ring, and U-shaped jump ring closed end is connected with microscope base, and U-shaped jump ring open end is positioned at strip shape through hole; Be provided with the light fixture for throwing light in described microscope base, and microscope base is provided with for contacting to close light fixture with cover plate or departing from the switching device to open light fixture with cover plate.
Cover plate of the present invention is in rotation process, the arc convex that arc groove on cover plate end face can promote in rotating shaft moves, namely the arc convex in rotating shaft and rotating shaft can be pushed and away from cover plate, until when in rotating shaft, the arc convex of annular boss is stuck in the arc groove of next cover plate end face, cover plate just can be in lockup state; In the process of rotating shaft away from cover plate, strip shape through hole in rotating shaft can extrude jump ring distortion, thus jump ring can store an elastic force in case spline axle comes off from cover plate and microscope base, and this elastic force can pull rotating shaft to be rotated further to prevent cover plate near cover plate when arc convex is stuck in next arc groove.Due to cover plate rotate time, the arc groove on cover plate needs the arc convex resistance that overcomes in rotating shaft less, so the arc groove of arc convex in rotating shaft and cover plate end face is not yielding, thus improves the service life of cosmetic lens device in this automobile; In addition, because arranging of jump ring can provide pulling force to avoid the disengaging of rotating shaft, jump ring can provide feedback force to passenger indirectly simultaneously, improves the traveling comfort that passenger uses; The pulling force that an axis can be provided to rotating shaft in strip shape through hole is connected to by jump ring open end; Be connected on microscope base by jump ring closed end, a benchmark can be provided to jump ring, avoid jump ring to followed by rotating shaft synchronizing moving and away from cover plate; Wherein, can make rotating shaft can be more steady in moving process vertically by the sliding block joint of guidepost and pilot hole, and then make rotating shaft moves axially in process radial runout can not occur away from the end of annular boss one end; In addition, by switching device and light fixture arrange cover plate can be made to open time light fixture connect user can be facilitated to throw light on, when cover plate is closed, light fixture can be closed automatically, thus user friendly practicality, and improves the traveling comfort of user.Therefore, the invention provides a kind of long service life, comfort is better and automatically can connects light fixture when cover plate is opened with lens device of making up in the automobile thrown light on to eyeglass.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Principle of work of the present invention: after cover plate is assembled by rotating shaft and microscope base, external force pulls in cover plate rotation process, the arc convex that on cover plate, the arc groove of the first through hole end face can promote annular boss inner end surface in rotating shaft along shaft axis away from cover plate first through hole end face; Rotating shaft is when moving along own axes, rotating shaft is adjacent to by the second plane on the first plane and microscope base, thus rotating shaft just cannot rotate relative to microscope base, namely rotating shaft is merely able to do to occur to move in axial sliding along rotating shaft relative to microscope base, and the annular boss of rotating shaft outer end then can slide in the second through hole; Time in the next arc groove of on the cover board the first through hole end face of the arc convex clamping on annular boss, user no longer continues to apply external force to cover plate, rotating shaft is under the elastic force effect of jump ring, rotating shaft can near the first through hole of cover plate end face to make the arc convex card on annular boss firm in arc groove, thus to make in automobile cosmetic lens device cover plate in opened condition, as shown in Figure 6.
Wherein, the principle of work of switching device is as follows: when cover plate and microscope base are opened, as shown in Figure 7, and extension spring pulls slide bar and flat board to move down, and makes the first plectrum of slide bar lower end contact to connect circuit with the second plectrum, thus opens light fixture with illumination; When cover plate and microscope base close, the locking that cover plate is subject to arc convex and arc groove in rotating shaft keeps closed condition, as shown in Figure 8, cover plate can promote fork and rotate in closing process, fork right part declines, and left part rises promote slide bar and overcomes the pulling force of extension spring with dull and stereotyped and rise, thus the first plectrum of slide bar lower end and the second plectrum are departed from, cut off, thus close light fixture.
