Description

Technical Field

[0001] This utility model patent relates to the field of headlamp manufacturing technology, and in particular to a rotatable headlamp. Background Technology

[0002] Headlamps are widely used in industrial rescue, outdoor sports, or other scenarios where lighting is required but it is inconvenient for personnel to hold the lamps themselves. To facilitate user use, headlamps are designed in various forms, including those that are directly mounted on helmets or detachable and in direct contact with the head, and so on.

[0003] The existing headlamp structure has the following technical problems:

[0004] 1. Mounted on a helmet: It must be used with a helmet, has a narrow range of applications, and is not suitable for everyday outdoor sports and other similar occasions.

[0005] 2. Those that come into direct contact with the head:

[0006] 2.1) When using the main headlights for illumination, the light range is mostly concentrated in front when the user is in an upward posture, resulting in low ground brightness and failing to provide a warning to vehicles passing by to the side and behind the user.

[0007] 2.2) The length direction of the headlamp's housing is the extension direction of the light strip. The angle between the housing and the light strip cannot be adjusted, so the illumination angle cannot be adjusted.

[0027] Example 1

[0028] A rotatable headlamp comprises two main parts: an overall lighting strip structure for mounting COB light strips 2, and a light box for housing circuit boards.

[0029] The overall lighting strip structure includes a silicone tape 1 with a mounting groove along its length. A COB light strip 2 is installed in the mounting groove. A fabric strip 3 is provided on the side of the silicone tape 1 that contacts the human body, to increase user comfort. Preferably, a sponge pad for sweat absorption and cushioning is provided between the fabric strip 3 and the silicone tape 1. The side of the fabric strip 3 that contacts the human body has anti-slip silicone matrix dots to enhance the user experience.

[0030] The overall lighting strip structure includes a lamp box mounting base 18. One end of the lamp box mounting base 18 is connected to one end of a silicone tape 1, and the other end of the lamp box mounting base 18 is provided with a tape positioning structure. The silicone tape 1 is positioned by the positioning structure after being wrapped around it. The positioning structure can be a positioning structure such as a seat belt buckle, or other detachable structures. The lamp box mounting base 18 has a lamp box mounting groove in the middle for mounting the lamp box structure, and the lamp box mounting base 18 is connected to the lamp box.

[0031] A cavity is formed between the housing 8 and the bottom cover 7 of the lamp box. Within this cavity are interconnected circuit boards I12, II14, III15, and a lamp board 13, providing circuit control for all the lamps. The housing 8 has an indicator lens 9 and a power display screen 11 on the front, a convex mirror 10 on one side, a charging plug 16 on the other side, and a switch button 17 on the top. The indicator lens 9 corresponds to the lamp position on circuit board III15, the power display screen 11 corresponds to the power display position on circuit board I12, and the convex mirror 10 corresponds to the lamp position on lamp board 13. Lamp board 13 is electrically connected to circuit board II14. A battery is mounted on circuit board I12, providing power to the entire system. The battery's charging port corresponds to the position of the charging plug 16.

[0032] The silicone mounting base 4 is fully embedded in the lamp box mounting base 18. The front end of the silicone mounting base 4 is provided with two claws 401. The claws 401 are inserted into the mounting slot 602 of the rotating base 6, so that the rotating base 6 and the silicone mounting base 4 are positioned and installed.

[0033] The bottom cover 7 has a structure for connecting and positioning with the pressure plate 5. This structure includes two cylinders and a circular groove corresponding to the circumference of the pressure plate 5. The cylinders are inserted into the two mounting holes of the pressure plate 5, thereby fixing the position of the bottom cover 7 and the pressure plate 5.

[0034] A rotating base 6 is mounted behind the bottom cover 7. The rotating base 6 has a pressing plate mounting hole 601 and a fixing base mounting groove 602.

The rear of the silicone mounting base 4 and the lamp box mounting base 18 are connected by a detachable method such as a slot, allowing the lamp box and the overall lighting strip structure to be separated into two parts. The lamp box can then be used as a flashlight. It should be noted that if this method is used, the COB light strip 2 and the lamp box need to be connected to an independent power supply device, or a pluggable interface device needs to be provided between the power supply line of the COB light strip 2 and the power output line of the lamp box.

[0040] Example 4

[0041] The rest of the structure is the same as in Embodiment 1, using a circuit structure to control all the lights and COB LED strips simultaneously. During use, the entire circuit system is turned on via switch button 17. Preferably, a mode conversion button is provided next to switch button 17, allowing simultaneous switching of the state of all lights and COB LED strips, including constant light mode, fast strobe mode, and slow strobe mode. When the user is running in dim light, such as on a secluded road, the button can be used to adjust to continuous lighting mode; when the user is running in good lighting conditions, such as on a busy road, the button can be used to adjust to strobe mode, serving as a warning to pedestrians and vehicles in the surrounding area.
