Abstract

The utility model relates to a rotatable headlight which belongs to illuminating devices for motor vehicles. Because a rotary mechanism formed by the combination of a casing of a spherical surface and a rotary shaft is adopted, the difficulties of bad directivity of the casing of a single spherical surface and the difficult assembling of two casings are overcome, and the defect that a single rotary shaft can not endure bigger vibration is overcome. The rotary shaft must be in the shaft line which is in the same direction of two spherical surface casings, a dust preventing device is added to reach high forming accuracy, and the fit clearance of spherical surfaces is ensured. The utility model can rotate at random in a definite control range, the rotatable headlight is not turned off when a driver drives at night, and the driver can observe the situation of the two sides at any moment.

Description

Rotatable headlight

This car light is the illumination equipment of power actuated vehicle.

Car light is in the past all fixed, though be provided with far and near light-light conversion device, uses still inconvenient.With regard to existing headlight, no matter be import or homemade, when night running two cars are met, in certain distance, all want switching off the headlamp.Influenced safe driving and conveying efficiency, particularly on the road surface of narrow curved, danger is bigger, even causes the accident.

In order to ensure traffic safety, improve conveying efficiency, developed the car light of a kind of can the revolution within the specific limits (vertical and level all turns), in its range of control, can shine any old place.

This lamp is by the housing and the horizontal shaft of three layers of dribbling face, and vertical axis and control corresponding system (forms such as stay-supported, electrodynamic type, pneumatic, hydraulic pressure are arranged) constitute.Its structure is: vacuum lampwick shown in the long and two-short dash line or reflective bell-type wick among Fig. 1,2, be fixed on the inner casing 4 with trim ring 10, inner casing 4 is installed in the mesochite 3 with vertical axis 2 again, and be that the center is subjected to horizontal guy 5 or Fig. 9-12(electrodynamic type with this axle) control of mechanism, in mesochite, do the rotation of horizontal direction.Mesochite 3 usefulness horizontal shafts 11 are installed in the shell 7, and are the center with this axle, are subjected to vertical backguy or Fig. 9-12(electrodynamic type) control of mechanism, in shell 7, do the rotation of vertical direction.A baseplane becomes 1/2 maximum angle of revolution (having a down dip before the shell) with housing axis base 8 is fixed in the outside of shell 7, and this base is installed on the big light fixtures of vehicle.During installation, left headlight is 1/2 maximum angle of revolution (its effect is the same with the angle of base and shell, but reduced volume) left, and right headlight is 1/2 maximum angle of revolution to the right.The difference of left side lamp and right lamp is: partly in the left side, right lamp is on the right side in the lamp in the horizontal steering unit of left lamp.Fig. 3-6 is a foot controller, triangle upper plate 19, and triangle lower plate 20 is formed a support with three studdles 18.A, B are housed above, three of C step on and turn round, control lamp level and vertical rotation.Be equipped with again on the triangle lower plate 20: rotary disk anchor shaft 13, rotary disk 14, pallet spring 15, pallet 16, end backguy 22 again, rotary disk retracing spring 23 etc. and end copy.This foot controller is positioned near the power-transfer clutch.Fig. 7, the 8th ends handle again.Be positioned near the gauge panel, it is made up of handle 25, nut 26, location bead 27, reed 28 and handle body 29 etc.The manipulation process of car light is: during meeting, the driver depresses stepping on of Fig. 3 and turns round the C(stay-supported), by the backguy 6 of Fig. 1, pulling mesochite 3 is along with the distance of car reduces, and light is stopped up to meeting by far away and near.The driver lifts pin, retracing spring (Fig. 1 12, Fig. 4 17) effect under reset.Reset as not needing, the handle 25 that can push back Fig. 7 can stop to a certain position at once.When left-handed turning or interim situation of observing the left side, step on stepping on of Fig. 3 and turn round A, backguy 5(Fig. 1) inner casing 4 of pulling Fig. 1 turns left.Trample and turn round the right lamp right-hand turning of B, step on A, C below left, step on B, C to the lower right.

This lamp without switching off the headlamp, is turned or when observing the both sides situation when nighttime meeting to the left and right, but the light left-right rotation.In the time of left the left side headlight to the left and right side headlight still forward according to, a left side was taken into account so in the past, on the contrary to the right.

Round headlinght commonly used on the current vehicle divides from size: 5 inch and 7 inch are arranged.Main of 5 inch is of a size of: the inner casing 4 sphere external diameter φ 168mm of Fig. 1 do not include the height 50mm of bead portion, the have an appointment crimping of 13mm of bottom-to-top-height 63mm() thickness 0.75mm.Revolution axis hole place point is welded with reinforcement iron (1mm).The sphere internal diameter φ 168mm of Fig. 1 mesochite 3, thickness 1mm, axis of revolution width between centers small end 32mm apart from big this section of end 8mm Internal Spherical Surface internal orifice place, is processed into straight tubular with attenuation, is convenient to install inner casing.The bottom-to-top-height of shell 7 is 113mm, axis of revolution width between centers outer casing back the inside 105mm, and apart from faucal 8mm, this section sphere also can be made straight tubular, internal diameter 170mm, the rear end is radius R 70mm, connects sphere and the rear end circular arc R 70mm of φ 170mm again with the camber line of 120mm.Apart from the place of axis of revolution center 65mm, fix (the inside countersunk head) baseplane becomes 15 ° of angles with housing axis base with four rivets.The tolerance clearance of each housing should be controlled in the 0.2-0.4mm.Level is 30 ° (a ' of Fig. 1) with vertical angle of revolution, and Fig. 3 steps on the L=35mm of the stroke H=Fig. 1 that turns round, the handle stroke S of Fig. 7, and the rotary disk 14 that should satisfy Fig. 4 turns round 30 ° of ≈ 12mm that are advisable.Material: Fig. 1 is 08,10 quality steel plates, other no specific (special) requirements.

Adopt DYN dynamic control system.Only the device of Fig. 9-12 is installed on the corresponding position and gets final product.Vertical control part is controlled two headlights simultaneously, and the limit switch that works should be in the wiring of motor negative pole that.
