Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1-12As shown, this embodiment provides an emergency headlamp, including a headband 1, which is semi-circular in shape. The headband 1 has telescopic fixing straps 33 connected to both ends. A connecting seat 2 is provided on the outer right side of the headband 1. A spotlight 4 is detachably mounted on the connecting seat 2 via a snap-fit ​​structure 3. A floodlight strip 5 is provided at the front end of the headband 1. A floodlight power supply battery 6, electrically connected to the floodlight strip 5, is provided on the left side of the headband 1. A wireless charging structure is provided between the connecting seat 2 and the spotlight 4. The wireless charging structure includes a wireless charging transmitter 23 located inside the spotlight 4 and a wireless charging receiver 8 located inside the connecting seat 2. The floodlight power supply battery 6 is electrically connected to the wireless charging receiver 8. In this emergency headlamp, the headband 1 is worn on the head, and the elastic fixing strap 33 is adjustable for tightness; the spotlight 4 is installed via the connecting base 2, and the floodlight strip 5 provides floodlight illumination; the wireless charging structure enables contactless charging between the spotlight 4 and the floodlight power supply battery 6; it can realize the basic lighting function of the headlamp, and the battery in the spotlight 4 can wirelessly charge the floodlight power supply battery 6 through the wireless charging structure. The battery in the spotlight 4 can also be charged via a wireless charger, reducing plugging and unplugging operations and improving convenience. Wireless charging avoids frequent plugging and unplugging, extending the interface life. The spotlight and floodlight are powered independently, improving reliability. Through modular design, wireless charging, optimized heat dissipation, and concealed wiring, it solves the problems of inconvenient disassembly and assembly, troublesome charging, and poor heat dissipation of existing headlamps, making it suitable for outdoor and rescue scenarios.

[0022] Specifically, refer to Figures 4-9 The latching structure 3 includes a fixed latch 9 mounted on the connecting seat 2 and a sliding latch 10 slidably mounted at the end of the connecting seat 2. A spring telescopic rod 11 is provided between the back of the sliding latch 10 and the back of the fixed latch 9. The hooks on the sliding latch 10 and the fixed latch 9 are arranged in opposite directions. The lamp housing 12 of the spotlight 4 is provided with two locking latches 13 that engage with the sliding latch 10 and the fixed latch 9. The hooks of the two locking latches 13 are arranged in opposite directions. In this embodiment, the sliding latch 10 slides under the action of the spring telescopic rod 11, and cooperates with the fixed latch 9 to lock the locking latches 13 of the spotlight 4. The opposite hook direction design ensures a stable engagement. This design allows for quick assembly and disassembly of the spotlight 4, preventing the spotlight from accidentally falling off. This design is convenient and quick to install, simplifies the steps, and improves the user experience.

[0023] In this embodiment, refer to Figures 4-9One end of the connecting seat 2 has an open mounting groove 7. The sliding buckle 10 is slidably installed in the mounting groove 7. The spring telescopic rod 11 is horizontally fixed in the mounting groove 7, and the end of the spring telescopic rod 11 is connected to the sliding buckle 10. A limiting block 47 is provided at the opening of the groove at the end of the mounting groove 7. The middle part of the connecting seat 2 has a through groove 34 that runs vertically through it. The fixing buckle 9 is a wedge block structure set on the groove wall at the top of the through groove. The sliding buckle 10 slides in the mounting groove 7, and the limiting block 47 restricts its stroke. The fixing buckle 9 of the wedge block structure is inserted into the through groove 34 by the locking buckle 13 and engages with the fixing buckle 9. The spatial layout of the buckle structure is optimized to ensure the stability of the spotlight after installation. The limiting block prevents the sliding buckle from excessive displacement and improves safety. The inclined surface structure of the wedge block makes it easy for the locking buckle 13 to slide into the through groove 34 after it abuts against the top surface of the fixing buckle 9.

[0024] Specifically, refer to Figures 4-9 The headband 1 has two clips 14 on its right end, which abut against the inner and outer sides of the headband 1, respectively. Bolts 15 pass through the headband 1 and connect to the connecting seat 2 on the clips 14. The connecting seat 2 has a countersunk hole 16 in its center, adapted to the bolts 15. The countersunk hole 16 has an internal hexagonal hole structure, and a hexagonal nut 46 connected to the bolts 15 is placed inside the countersunk hole 16. In this embodiment, the bolts 15 pass through the clips 14 and the headband 1, and are fastened to the hexagonal nut 46 in the countersunk hole 16, providing a detachable connection method, concealing the nut structure, improving aesthetics, preventing protrusion of the internal hexagonal countersunk hole, reducing the risk of impact, and the clip design distributes force to prevent headband deformation.

[0025] Specifically, refer to Figures 7-9 The bottom surface of the connecting seat 2 is provided with a base plate 35 that connects to the headband 1. The base plate 35 has two parallel arc-shaped sliding grooves 17, which correspond to the mounting groove 7 and the through groove 34. Two clamping pieces 14 are provided with sliding pins 18 that pass through the headband 1, and these sliding pins 18 are adapted to the arc-shaped sliding grooves 17. In this embodiment, the arc-shaped sliding grooves 17 on the base plate 35 cooperate with the sliding pins 18 of the clamping pieces 14. The sliding pins 18 move along the arc-shaped sliding grooves 17 to adjust the illumination angle of the spotlight 4; this allows for multi-angle adjustment of the spotlight, and the arc-shaped track ensures smooth adjustment and prevents loosening.

[0026] Specifically, refer to Figures 1-4The spotlight 4 includes a lamp housing 12 and a lamp head 19, a built-in battery 20, and a main control circuit board 21 disposed within the lamp housing 12.
