The front end of the front tub 1 and the rear end of the rear tub 2 are respectively provided with a front glass cover 3 and a rear baffle 4 having a central through hole. The butt joint of the front lamp barrel 1 and the rear lamp barrel 2 respectively extend inwards to form a front inner retainer ring and a rear inner retainer ring, the distance between the front inner retainer ring and the rear inner retainer ring is matched with the edge thickness of the rear convex parabolic curve mirror surface large reflector 5 with a middle perforation, and the rear convex large reflector 5 is clamped and fixed in the front inner retainer ring and the rear inner retainer ring.
As shown in fig. 2, the inside of the headlight bucket 1 is fixedly connected with the central ring seat 1-2 through the front radial ribs 1-1. The rear baffle 4 is fixedly connected with the fixed seat 6 through a flange 4-1 in the middle, a central sleeve 8-1 for inserting a focusing screw hole shaft 8 is fixed in a central hole of the fixed seat 6, and a radial guide pin 8-2 with the inner end extending into an axial chute of the focusing screw hole shaft 8 is arranged on the central sleeve 8-1, so that an axial moving pair is formed, and the focusing screw hole shaft 8 can axially move relative to the fixed seat 6.
The central ring seat 1-2 and the focusing screw hole shaft 8 are respectively connected with the front end and the rear end of the high-power xenon lamp light source 9, and the specific connection relation is as follows: the crown spring 10 is arranged in the central hole of the central ring seat 1-2, and the contact pin 9-1 tightly inserted in the crown spring 10 is arranged on the front end insulating head 9-5 of the light source 9, so that the light source is easily inserted in the central hole of the central ring seat 1-2 by means of the guiding of the contact pin to form a damping moving pair, and the focusing and positioning are convenient.
The rear end of the light source 9 is fixedly connected with the focusing screw hole shaft 8 through the conductive seat 9-2 and the insulating seat 9-3 which are fixedly connected with the light source. The screw hole at the rear end of the focusing screw hole shaft 8 and the inner end of the focusing screw rod 11 form a screw pair, the outer end diameter-reducing section of the focusing screw rod 11 is inserted into the central hole of the flange plate 4-1 of the rear baffle plate 4 and then is fixedly connected with a knob 12 positioned outside the rear baffle plate 4 through a hanging screw, so that an axial constraint rotating pair is formed with the rear baffle plate 4. When the knob is screwed, the focusing screw hole shaft and the light source can be axially displaced together through the screw pair.
As shown in fig. 3 and 4, the front insulation head 9-5 of the light source 9 is provided with an annular semicircular arc positioning concave 9-4, inserted into a central sleeve at the front end of the squirrel cage bracket 13, and radial positioning marbles 13-1 of the central sleeve are embedded into the positioning concave 9-4 for positioning and then fixedly connected with a fastener through a squirrel cage connecting plate. When the contact pin on the light source is installed in the crown spring, the marble falls into the positioning concave to lock the light source; when the light source is replaced, only the flange plate on the rear baffle plate is detached, force is applied to the rear baffle plate, and the marble is compressed and unlocked by the positioning concave, so that the contact pin and the crown spring are separated, and the front windshield is not required to be opened; when the light source is installed, the pinball positioning structure ensures repeated positioning accuracy. The rear end of the cage support 13 is fixed with a front convex fresnel lens 14 with a central perforation.
