Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electric bicycle lamps, and in particular to an electric bicycle lamp with adjustable illumination angle. Background Art
[0002] The lights of electric bicycles are important components to ensure riding safety. They are composed of a lamp holder, a light source, a lampshade and a reflector. The design of the lights focuses on the intensity and range of light, which can effectively illuminate the road ahead. Some lights also have the function of switching between high and low beams to adapt to different riding scenarios.
[0003] In the prior art, there are electric bicycle lights with adjustable illumination angles, which can adjust the illumination angle of the lights to ensure that the road surface is fully illuminated and avoid blind spots. When meeting other vehicles, the angle can be appropriately lowered to avoid dazzling the oncoming drivers and reduce the occurrence of traffic accidents.
[0004] The main function of the reflector of an electric bicycle headlight is to reflect and focus the light emitted by the bulb to form a specific lighting shape and range; however, after the illumination angle of the electric bicycle headlight is adjusted, the focal point of the light of the electric bicycle headlight changes, and the originally designed light focusing position will shift, resulting in changes in the concentration and brightness distribution of the light, and after the illumination angle of the headlight is rotated, the light pattern will be distorted, and astigmatism and uneven light spots may occur, resulting in a weakened lighting effect, which in turn causes limitations.
[0005] To this end, we propose an electric bicycle light with adjustable illumination angle. Summary of the invention

[0012] By enclosing the No. 1 reflector and the No. 2 reflector into a cylindrical shape to act as a reflector, when the lamp holder moves with the No. 2 fixing ring, the No. 1 reflector and the No. 2 reflector can swing with the lamp holder, so that the light source emitted by the lamp holder is located in the middle position of the No. 2 reflector, thereby alleviating the situation where the focus position of the light emitted after the position of the lamp holder is changed is offset.
[0013] Preferably, the No. 1 reflector and the No. 2 reflector are divided into two groups; the two groups of the No. 1 reflector and the No. 2 reflector are arranged inside and outside in a staggered manner.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 4, 5 and 7, an electric bicycle light with adjustable illumination angle, comprising:
[0031] A housing 1, a lampshade 2 and a lamp holder 3; the lampshade 2 is mounted on the housing 1; a light source is fixedly connected to the lamp holder 3; a transverse adjustment frame 4 is fixedly connected to the housing 1; a moving block 41 is slidably connected to the transverse adjustment frame 4; a longitudinal adjustment frame 42 is fixedly connected to the moving block 41; the lamp holder 3 is slidably connected to the longitudinal adjustment frame 42; an adjustment motor 43 is fixedly connected to both the moving block 41 and the lamp holder 3; an adjustment roller is fixedly connected to the output end of the adjustment motor 43; the adjustment roller is in contact with the corresponding transverse adjustment frame 4 and longitudinal adjustment frame 42;
[0032] A reflective component is arranged on the housing 1; the reflective component is spliced into a reflector, which can swing along with the movement of the lamp holder 3, thereby reducing the focus position deviation of the light emitted by the lamp holder 3 after the lamp holder 3 moves.
[0033] In the present invention, the reflective assembly includes a first reflector 5, a second reflector 51, a first fixing ring 52 and a second fixing ring 53; the first fixing ring 52 is fixedly connected to the housing 1, and a connecting rod 54 is spherically hinged on the first fixing ring 52 and the second fixing ring 53; the first reflector 5 is fixedly connected to the connecting rod 54 on the first fixing ring 52; the second reflector 51 is slidably connected to the first reflector 5;
[0034] The second fixing ring 53 is movably mounted on the housing 1 ; the connecting rod 54 on the second fixing ring 53 is fixedly connected to the second reflector 51 ; the first reflector 5 and the second reflector 51 form a circle, and the inner side is set as a mirror surface.
[0035] The present invention is installed on an electric bicycle. When the rider rides the electric bicycle, he turns on the light source on the lamp holder 3 to illuminate the front of the electric bicycle when the vision is dim. When the illumination angle needs to be adjusted, the adjustment motor 43 on the moving block 41 drives the corresponding adjustment roller to rotate, so that the moving block 41 moves laterally along the transverse adjustment frame 4 with the longitudinal adjustment frame 42 and the lamp holder 3. At the same time, the adjustment motor 43 in the lamp holder 3 drives the corresponding adjustment roller to rotate, so that the lamp holder 3 moves longitudinally along the longitudinal adjustment frame 42, thereby adjusting the angle of the lamp holder 3 in the transverse and longitudinal directions, so that the illumination angle of the present invention is adjusted.
[0036] When the position of the lamp holder 3 is adjusted, the lamp holder 3 drives the second fixing ring 53 to move together, so that the second fixing ring 53 moves with the corresponding first fixing rod, so that the second reflector 51 and the first reflector 5 swing along with the second fixing ring 53, and the first reflector 5 and the second reflector 51 are slidably matched, and the first reflector 5 and the second reflector 51 are connected to the corresponding first fixing ring 52 and the second fixing ring 53 through the first connecting rod 54. Therefore, when the first reflector 5 and the second reflector 51 swing along with the second fixing ring 53, the first reflector 5 and the second reflector 51 can slide against each other, and the movement of the second fixing ring 53 will not be affected.
[0037] The present invention forms a cylindrical shape with the first reflector 5 and the second reflector 51 to act as a reflector. When the lamp holder 3 moves with the second fixing ring 53, the first reflector 5 and the second reflector 51 can swing with the lamp holder 3, so that the light source emitted by the lamp holder 3 is located in the middle of the second reflector 51, thereby alleviating the problem of the focus position of the light emitted after the position of the lamp holder 3 is changed.
[0038] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 7 In the present invention, the first reflector 5 and the second reflector 51 are divided into two groups; the two groups of the first reflector 5 and the second reflector 51 are arranged inside and outside in a staggered manner.
[0039] In the present invention, a first flexible corrugated ring 56 is fixedly connected to the first fixing ring 52; a second flexible corrugated ring 57 is fixedly connected to the second fixing ring 53; the other end of the first flexible corrugated ring 56 is fixedly connected to the first reflector 5; the other end of the second flexible corrugated ring 57 is fixedly connected to the second reflector 51.
[0040] In the present invention, two groups of inner and outer No. 1 reflectors 5 and No. 2 reflectors 51 are arranged, and the two groups of No. 1 reflectors 5 and No. 2 reflectors 51 are arranged alternately, so that when the No. 1 reflectors 5 and No. 2 reflectors 51 swing with the lamp holder 3, no gap will be left between two adjacent No. 1 reflectors 5, and a No. 1 flexible corrugated ring 56 and a No. 2 flexible corrugated ring 57 are arranged on the No. 1 fixing ring 52 and the No. 2 fixing ring 53, so that the gap between the No. 1 reflector 5 and the No. 1 fixing ring 52 and the gap between the No. 2 reflector 51 and the No. 2 fixing ring 53 can be sealed without affecting the swing of the No. 1 reflector 5 and the No. 2 reflector 51, thereby reducing light dispersion.
[0041] In the present invention, a sliding groove 58 is provided on the inner group of No. 2 reflectors 51; a No. 1 connecting plate 59 is fixedly connected between the sliding grooves 58 on the two adjacent No. 2 reflectors 51 on the inner side, and a No. 2 connecting plate 6 is slidably connected thereto; the No. 1 connecting plate 59 and the No. 2 connecting plate 6 are alternately arranged; and a connecting block 61 is fixedly connected to the No. 2 connecting plate 6 and contacts the top of the outer group of No. 1 reflectors 5.
[0042] In the present invention, a connecting spring 62 is fixedly connected in the sliding groove 58 ; the connecting spring 62 is fixedly connected to the second connecting plate 6 .
[0043] In the present invention, the width of the sliding groove 58 is greater than the width of the second connecting plate 6 .
[0044] In the present invention, a first connecting plate 59 and a second connecting plate 6 are arranged between a group of second reflectors 51 on the inner side, and the second connecting plate 6 is slidably connected, so that the first connecting plate 59 and the second connecting plate 6 block the gap between the second connecting plate 6. Therefore, when the second reflector 51 swings, the first reflector 5 contacts the connecting block 61 to push the second reflector 51 to move, so that the second connecting plate 6 can cover the gap between the second reflectors 51 without affecting the swing of the first reflector 5. In addition, the width of the sliding groove 58 of the present invention is greater than that of the second connecting plate 6. Therefore, when the second connecting plate 6 with an inclined side moves, it will not conflict with the side wall of the sliding groove 58 and cannot move.
[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected; the scope of the present invention to be protected is defined by the attached claims and their equivalents.
