Description
Technical field
The utility model relates to display device, especially relates to a kind of display device hand turnover mechanism.
Background technique
Existing Vehicular display device mounting type is divided into fixed, electric turnover formula and handheld turnover.Existing car-mounted manual turning-over displaying apparatus mainly contains air spring structure, friction structure and fluted disc electromagnetic brake type structure etc., the shortcoming of first two structure hooks screen body for needing grab when being incorporated into roof, open angle cannot be regulated in use, particularly the first structure, when in the open position, swing severe, even abnormal sound.Add that band grab scaffold size certainly will become large by television sizes affects, affect in car attractive in appearance, increase the erection weight of in-car TV.Meanwhile, for roof mounting plane and bury iron propose requirements at the higher level.Though the third fluted disc electromagnetic brake type structure exists axle running clearance, screen body swings obviously, and easily can regulate open angle, to adapt to different roof angle, scaffold area is little, lightweight, and the individual character moulding of roof being buried to iron and roof is provided convenience.
Summary of the invention
The purpose of this utility model is as meeting roof interior trim individual demand, reduces car roof skeleton embedded iron area, alleviates in-car TV weight, reduces display screen at the oscillating quantity of car movement process and abnormal sound, provides a kind of display device hand turnover mechanism.
The utility model is provided with friction component, electromagnetic braking assembly and fixing frame;
Described friction component is provided with flange shaft, base, lower friction plate, upper friction plate, upper cover; Lower friction plate to be located on base and to be put into flange shaft and upper friction plate successively, and upper cover is placed on upper friction plate, base and on cover and be provided with through hole, base and upper cover are by screw fastening and adjust screw degree of tightness according to required torsion;
Described electromagnetic braking assembly is provided with yoke lid, coil, yoke, stage clip, flange tooth, flange tooth, fore bearing, bearing support, rear bearing, flange shaft; Described fore bearing and rear bearing are inserted in bearing support, and flange tooth through rear bearing and fore bearing, then is inserted in flange shaft by flange shaft; Coil is located in yoke, and yoke covers yoke lid, and the hole be located in yoke put into by stage clip, and the spline pin be located in yoke is aimed in the spline hole be located on flange tooth and pushes in yoke, yoke is tightly locked on bearing support.
Axial one end of the present utility model adopts the electromagnetic brake improved, and coil and running shaft are arranged oppositely, and it is less that engagement fluted disc can do, thinner what meet make displays under anti-rotation torque condition.The axle the other end adopts friction structure, and when this structure one can prevent break from throwing off, screen gets rid of fast under Gravitative Loads, protection passenger safety; Two can eliminate the rotation backlass that break fluted disc spline pin glade plane space causes, thus eliminate screen body and rock the sound and protection fluted disc is impacted; Axle is made hollow and be can be used to threading, makes display device cabling more attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the utility model embodiment.
Fig. 2 is the friction component STRUCTURE DECOMPOSITION schematic diagram of the utility model embodiment.
Fig. 3 is the electromagnetic braking modular construction decomposing schematic representation of the utility model embodiment.
Embodiment
See Fig. 1 ~ 3, the utility model embodiment is provided with friction component 1, electromagnetic braking assembly 2 and fixing frame 3.
Described friction component 1 is provided with flange shaft 11, base 12, lower friction plate 13, upper friction plate 14, upper cover 15; Lower friction plate 13 is located on base 12 and is also put into flange shaft 11 and upper friction plate 14 successively, and upper cover 15 is placed on upper friction plate 14, and base 12 and upper cover 15 are provided with through hole, and base 12 and upper cover 15 are by screw fastening and according to required torsion adjustment screw degree of tightness.
Described electromagnetic braking assembly 2 is provided with yoke lid 21, coil 22, yoke 23, stage clip 24, flange tooth 25, flange tooth 26, fore bearing 27, bearing support 28, rear bearing 29, flange shaft 201; Described fore bearing 27 and rear bearing 29 are inserted in bearing support 28, and flange tooth 26 through rear bearing 29 and fore bearing 27, then is inserted in flange shaft 201 by flange shaft 201; Coil 22 is located in yoke 23, yoke 23 covers yoke lid 21, the hole 232 be located in yoke 23 put into by stage clip 24, and the spline pin 231 be located in yoke 23 is aimed in the spline hole 251 be located on flange tooth 25 and pushes in yoke 23, yoke 23 is tightly locked on bearing support 28.
Below provide using method of the present utility model:
1, open: press switch, coil 22 is energized, flange tooth 25 moves to carrying flange tooth 26 direction under the effect of magnetic force, until disengagement and flange tooth 26 engage, and compression press spring 24, now flange tooth 26 loses the constraint of flange tooth 25, display device can fall due to deadweight, but by the effect of friction assembly, can't drop suddenly, need to break display device with hand, naturally desired location is dropped to after overcoming frictional force, at this moment pass is unclamped, coil 22 dead electricity, flange tooth 25 loses magnetic force, under the effect of stage clip 24, to the motion of flange tooth 26 direction until engage with flange tooth 26.If be subject to road conditions the impact such as to jolt, the swing of display device also can first be cushioned by friction component, and last method tooth can not surprisingly be opened carrying out stressed guarantee display.
2, close: press switch, coil 22 is energized, and flange tooth 25 moves to carrying flange tooth 26 direction under the effect of magnetic force, until disengagement and flange tooth 26 engage, and compression press spring 24, flange tooth 26 loses the constraint of flange tooth 25, to close display device with hand, after overcoming frictional force, natural rotation is to roof, at this moment unclamp pass, coil 22 dead electricity, flange tooth 25 loses magnetic force, under the effect of stage clip 24, to the motion of flange tooth 26 direction until engage with flange tooth 26.If be subject to road conditions the impact such as to jolt, the swing of display device also can first be cushioned by friction component, and last method tooth can not surprisingly be opened carrying out stressed guarantee display.
