Description

Technical Field

[0001] The utility model relates to a motorcycle, in particular to a front decorative lamp of a motorcycle. Background Art

[0002] Motorcycle front decorative lights play an important role in the design and decoration of motorcycles. They not only increase the appearance appeal of the motorcycle, but also provide additional lighting or warning functions in some cases.

[0003] Existing front decorative lights, such as a motorcycle decorative light disclosed in the China Patent Library (application number: 99207307.3), are composed of a lampshade, a reflector, a circuit board, a base plate and a power cord; wherein the lampshade covers the electronic components on the circuit board; there are 10 holes for placing light-emitting diodes and 1 hole for placing capacitors on the front of the reflector, and there are 4 bayonet holes on its side.

[0004] In the above-mentioned decorative lamp, 10 light emitting diodes are arranged to diffuse the light evenly without dead angles. However, currently motorcycle decorative lamps are generally small in size, and more light emitting diodes are likely to increase the heating of the decorative lamp and affect its lifespan.

[0007] Each lamp bead corresponds to a step with a concave arc bottom, and the cross-section of the bottom of the step is serrated, so that the light emitted by the lamp bead is evenly diffused around through reflection from the bottom of the step, thereby expanding the lighting range and reducing blind spots. In this way, a smaller number of lamp beads can be used to obtain better lighting effects in actual use, thereby reducing the heat generation of decorative lamps and extending their lifespan.

[0008] In the above motorcycle front decorative lamp, a slot matching the circuit board is provided on the rear side of the partition, and the front side of the circuit board is clamped in the slot; a clearance opening is penetrated through the side wall of the slot to connect the inner cavity of the slot to the corresponding reflection cavity, and the number of the clearance openings and the lamp beads are the same and the positions are directly opposite. The circuit board is directly clamped into the slot for positioning, which has the advantages of simple structure and convenient installation.

[0009] In the above-mentioned motorcycle front decorative light, a baffle is fixed on the outer side of the bottom wall of the slot, and the front end face and the rear end face of the circuit board are respectively pressed tightly against the bottom wall of the slot and the baffle to prevent the circuit board from falling out of the slot, thereby enhancing the positioning strength and stability of the circuit board and ensuring the stable operation of the decorative light.

[0010] In the above motorcycle front decorative light, the baffle is L-shaped, one end of the baffle is fixedly connected to the groove body and contacts the rear end surface of the circuit board, and the inner side of the other end of the baffle is pressed on the side surface of the circuit board to further enhance the positioning strength of the circuit board.

A through hole is provided on the baffle that is opposite to the internal threaded tube, and the baffle is fixedly connected to the groove body by a screw that passes through the through hole and is screwed into the internal threaded tube to further facilitate the installation of the baffle.

[0012] In the above-mentioned motorcycle front decorative lamp, the groove body is an integrated structure, which is convenient for processing and assembly.

[0013] In the above motorcycle front decorative lamp, a positioning cylinder coaxial with the cavity is formed on the bottom wall of the cavity, the shape and size of the positioning cylinder match the slot body, and the rear side of the slot body is clamped in the positioning cylinder. With the above design, installation can be completed by simply pressing into the slot body, which has the advantages of simple structure and convenient assembly.

[0014] In the above motorcycle front decorative lamp, the inner diameter of the positioning tube gradually decreases from front to back, and the edge of the slot body notch presses on the inner wall of the lampshade to effectively limit the slot body in the front and rear directions, making the positioning of the slot body more stable.

[0016] 1. Each lamp bead corresponds to a step with a concave arc bottom, and the cross-section of the bottom of the step is serrated, so that the light emitted by the lamp bead is evenly diffused around through reflection from the bottom of the step, thereby expanding the lighting range and reducing blind spots. In this way, a smaller number of lamp beads can be used in actual use to obtain better lighting effects, thereby reducing the heating of decorative lamps and extending their lifespan.

[0017] 2. The inner diameter of the positioning tube gradually decreases from front to back, and the edge of the slot is pressed against the inner wall of the lampshade to effectively limit the slot in the front and rear directions, making the positioning of the slot more stable, thereby avoiding abnormal noise and ensuring the stable operation of the decorative lamp.

A partition 4a is formed in the slot body 4 to divide the inner cavity of the slot body 4 into two reflecting cavities 4b arranged side by side on the left and right, and the two reflecting cavities 4b are arranged in rotational symmetry. The bottom wall of the reflecting cavity 4b is composed of a plurality of steps distributed continuously from top to bottom, and the step is composed of a step side 4b1 and a step bottom 4b2, and the step bottom 4b2 and the step side 4b1 are alternately distributed from top to bottom. The step bottom 4b2 is a concave arc surface, and the cross section of the step bottom 4b2 is serrated. The circuit board 3 is fixed on the partition 4a, and lamp beads 5 are installed on both the left and right sides of the circuit board 3. The number of lamp beads 5 and the number of steps are the same, and each lamp bead 5 faces the corresponding step.

[0027] Each lamp bead 5 corresponds to a step with a concave arc bottom, and the cross-section of the step bottom surface 4b2 is serrated, so that the light emitted by the lamp bead 5 is evenly diffused around through reflection by the step bottom surface 4b2, thereby expanding the lighting range and reducing lighting blind spots. In this way, a smaller number of lamp beads 5 can be used in actual use to obtain better lighting effects, thereby reducing the heat generation of decorative lamps and extending their lifespan.

[0028] In this embodiment,

[0029] like Figure 2 and Figure 3 As shown, the circuit board 3 is installed as follows: a card slot matching the circuit board 3 is provided on the rear side of the partition 4a, and the front side of the circuit board 3 is carded in the card slot; a clearance opening 4c is penetrated on the side wall of the card slot so that the inner cavity of the card slot is connected to the corresponding reflection cavity 4b, and the clearance opening 4c and the lamp beads 5 are the same in number and their positions are directly opposite.
