Abstract
Description
Technical Field
[0001] The utility model relates to a headlamp device, in particular to an adjusting structure for the irradiation angle of a headlamp. Background Art
[0002] As a mobile lighting device, the headlamp has been widely used in more and more usage scenarios such as outdoor sports and working in dark environments because of its advantages such as convenient use and freeing hands. During the use of the headlamp, the user needs to adjust the irradiation angle of the headlamp according to the observed distance. When observing a relatively long distance, the irradiation angle of the headlamp needs to be adjusted upward to make the headlamp irradiate nearly horizontally. When observing the ground at a relatively close distance, the irradiation angle of the headlamp needs to be adjusted downward. Currently, the headlamps on the market generally adopt the method of relative rotation between the headlamp body and the headlamp bracket to adjust the irradiation angle. Elastic buckles are arranged on the headlamp bracket and cooperate with several tooth shapes on the headlamp body to fix the headlamp body at a certain angle so that it irradiates in a certain direction. This adjustment method has the following problems;
[0003] 1. The reliability of the plastic elastic buckle is poor and it will age during long-term use, resulting in deformation or insufficient elasticity, and being unable to fix the headlamp body;
[0004] 2. There is a headlamp bracket separating between the headlamp and the user's forehead, and the center of gravity is relatively far. During the movement, the headlamp shakes greatly and the wearing is uncomfortable;
[0005] 3. When adjusting the irradiation angle of the headlamp, the position of the center of gravity changes, making its center of gravity unstable. Content of the Utility Model

One end of the sensor is in contact with one end of the magnet. The sensor controls the corresponding LED lamp to light up by identifying the magnetic pole direction of the magnet. When the magnet rotates, the sensor senses the change in the magnetic pole direction of the magnet and switches different LED lamps to light up;
