Detailed Description
The invention will be further described with reference to the following figures and examples: the light source card for the motorcycle headlamp, as shown in fig. 1, is disposed at the rear side of the lamp bowl 15, and integrates the light source 16 and the lamp bowl 15.
A ring-shaped lamp holder 9 fixed with the lamp bowl is arranged at the center of the back side of the lamp bowl 15, and the lamp holder 9 can be made of metal materials. The edges of the two opposite sides of the lamp holder 9 are integrally provided with a first clamping seat 1 and a second clamping seat 13 which rise backwards, namely, the backward direction refers to the direction of the light axis emission of the lamp bowl is the front direction, and the reverse direction is the back direction, relative to the lamp bowl. As shown in fig. 2, the first clamping seat 1 and the second clamping seat 13 are set to be equal in height and are higher than the rear end of the lamp bowl by 4-8 mm. The top surfaces of the first clamping seat 1 and the second clamping seat 13 are respectively covered with a first pressing piece 3 and a second pressing piece 12 fixed by the fastening nail 2, and the first pressing piece 3 and the second pressing piece 12 are used as a fixing and limiting base of the light source card.
A cover plate 8 is arranged in the annular lamp holder 9, a through hole is formed in the center of the cover plate 8, and a light source holder 6 penetrates through the through hole from the front to the back. As shown in fig. 2, the light source base 6 is integrally provided with a horizontally protruding ring of pressing plate 17, the pressing plate 17 is sandwiched between the lamp bowl 15 and the cover plate 8, and is actually pressed by the cover plate 8, and the cover plate is pressed by the light source card.
As shown in fig. 1, a protrusion 19 is disposed on one side of the cover plate 8 between the first clamping seat 1 and the second clamping seat 13, the protrusion 19 is provided with a through hole perpendicular to the radial direction, and a cover plate rotating shaft 14 is disposed through the through hole and embedded into the lamp holder 9 at two ends. When the cover plate 8 is not pressed by the light source card, the cover plate can rotate around the cover plate rotating shaft 14 when the cover plate is free from obstacles, and when the cover plate 8 is uncovered, the light source base 6 below can be directly taken out and replaced.
When the cover plate 8 is covered on the pressure plate 17 of the light source base 6, two sides of the cover plate 8 are pressed and fastened on the pressure plate 17 by a bent steel wire 4, and the steel wire 4 is limited by the first pressing piece 3 and the second pressing piece 12 respectively. The utility model discloses the light source card that indicates here steel wire 4 promptly, about 4 mm of steel wire diameter, because the elasticity of steel wire, can keep lapping 8 and keep establishing on pressure disk 17.
As shown in FIG. 1, a hook 10 having a lower opening is provided on one side of the second presser plate 12, and the orientation "lower" herein is referred to as the state viewed in FIG. 2. A through groove 18 which is tangential relative to the lamp holder 9 is arranged between the first pressing piece 3 and the first clamping seat 1, and the steel wire 4 is folded back after passing through the through groove 18, so that the part of the steel wire which can pass through the through groove 18 rotates as a rotating shaft. The steel wires 4 on two sides of the through groove 18 are respectively clamped on two sides of the light source seat 6, and the steel wires 4 on two sides of the light source seat 6 are bent downwards and pressed on the upper surface of the cover plate 8. The first end of the steel wire 4 bends downwards to press the upper surface of one side of the cover plate 8 and then rises to become the tail end of the light source card, and the first end of the steel wire 4 keeps pressing force on the cover plate 8 due to the height limitation of the through groove 18. The second end of the steel wire 4 is bent downwards and then rises at the other side of the cover plate 8, the steel wire horizontally bends to form a pressing handle 11 after passing through the lower part of the hook 10, the rising elastic potential energy is still kept after the steel wire 4 is limited by the hook 10, and the steel wire at the corresponding side keeps enough pressure on the cover plate.
The middle part of the cover plate 8 sinks to form a cover plate groove 7, and the position of the steel wire 4 abutting against the cover plate 8 is arranged in the cover plate groove 7. The cover plate groove 7 can block the restriction of the outward movement of the steel wire 4. So that the steel wire 4 as the light source card keeps stable pressure on the cover plate 8 and the pressing plate 17 pressed under the cover plate, thereby ensuring the stability of the light source seat 6 connected with the pressing plate 17 and the light source 16 at the lower part of the light source seat 6. The top of the light source seat 6 is provided with a pair of light source electrodes 5, and the power supply plug only needs to be plugged into the light source electrodes 5 to complete the power supply connection of the light source.
When changing the light source, only need pull out the power supply plug who connects at a pair of light source electrode 5, push down the pressure handle 11 and move to the outside, make steel wire 4 break away from couple 10, alright this moment can rotate steel wire 4 around leading to groove 18 and raise, the contact is to the pressure of apron 8, apron 8 rotates around apron pivot 14 and opens, just can take out light source seat 6, change the new light source seat of taking the light source, cover apron 8, push down steel wire 4 under the couple, connect the power supply plug, can accomplish the change of light source fast, reliably.
