Description

Technical Field

[0001] This utility model belongs to the field of headlamp technology, specifically relating to a detachable headlamp. Background Technology

[0002] Headlamps, as portable lighting devices, are widely used in outdoor activities, mining operations, nighttime construction, and other scenarios. Existing headlamps typically consist of a battery box, lamp body, switch, and mounting structure. Users secure the headlamp to their head by wearing a headband, allowing for hands-free operation.

[0003] However, in existing technologies, most headlamps have a relatively enclosed battery compartment design, with the top cover typically secured by screws or adhesive. This not only increases assembly complexity but also requires tools for battery replacement or circuit maintenance, making operation inconvenient and maintenance inefficient. Furthermore, frequent disassembly and reassembly of screws or adhesives can easily lead to loosening or structural damage, reducing product lifespan and user experience.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0007] Furthermore, the battery box has symmetrical headlamp connection parts on both sides of its surface, and a headlamp protrusion on the lower side of the headlamp body. The headlamp protrusion is located between the two headlamp connection parts. A connection through hole is opened on the side of the headlamp connection part, and a connection through groove is opened on the side of the headlamp protrusion. The connection through hole and the connection through groove correspond to each other and are hinged to each other by fasteners passing through the connection through hole and the connection through groove.

[0008] Furthermore, the surface of the mounting cover is provided with a display mounting slot and a charging mounting slot in the middle.

[0009] Furthermore, the mounting cover has symmetrical button mounting slots on both sides of its surface.

[0010] Furthermore, the battery box has headband connectors symmetrically located on both the left and right sides.

[0011] The present invention has the following advantages: the upper end cover of the battery box is equipped with an installation cover, the upper edge of the battery box is provided with a first engaging protrusion, the lower edge of the installation cover is provided with a second engaging protrusion, the outer side of the first engaging protrusion is provided with a first connecting buckle, the inner side of the second engaging protrusion is provided with a second connecting buckle, the second engaging protrusion is connected to the outer side of the first engaging protrusion, and the second connecting buckle is engaged with the first connecting buckle. The headlamp of the present invention realizes quick installation and removal of the top cover, and the user can open the top cover without tools to replace the battery or maintain the internal circuit, which improves the convenience of use and maintenance efficiency.

Detailed Implementation

[0016] like Figures 1 to 3 As shown, a headlamp includes a battery box 10 and a headlamp body 20. The headlamp body 20 is movably connected to the battery box 10. The battery box 10 has symmetrical headband connectors 11 on its left and right sides. In use, the two headband connectors 11 are respectively connected to headbands. The headbands are made of elastic material or have an adjustment mechanism, so that the user can adjust the tightness of the headlamp according to their own needs, so that the headlamp is securely fixed on the head.

[0017] In practical implementation, the upper end cover of the battery box 10 is equipped with a mounting cover 12. The upper edge of the battery box 10 has a first engaging protrusion 13, and the lower edge of the mounting cover 12 has a second engaging protrusion 121. The outer side of the first engaging protrusion 13 has a first connecting buckle 131, and the inner side of the second engaging protrusion 121 has a second connecting buckle 122 that is adapted to the first connecting buckle 131. During installation, the second engaging protrusion 121 is connected to the outer side of the first engaging protrusion 13, and at the same time, the second connecting buckle 122 is engaged with the first connecting buckle 131, so that the mounting cover 12 can be detachably mounted on the upper end of the battery box 10. During use, the user can easily remove the mounting cover 12 from the upper end of the battery box 10, thereby facilitating battery replacement or maintenance of internal components of the battery box. Compared to the traditional method of fixing with glue, this structural design has significant advantages such as simple structure, repeated disassembly and assembly, and convenient maintenance. It effectively solves the problems of troublesome disassembly and assembly of the top cover and difficulty in maintenance, and improves the practicality of the product and user experience.

[0018] In practical implementation, the battery box 10 has symmetrical headlamp connecting parts 14 on both sides of its surface, and the headlamp body 20 has a headlamp protrusion 21 on its lower side. The headlamp protrusion 21 is located between the two headlamp connecting parts 14. The side of the headlamp connecting part 14 has a connecting through hole 141, and the side of the headlamp protrusion 21 has a connecting groove 211. The connecting through hole 141 and the connecting groove 211 correspond to each other and are hinged to each other by fasteners passing through the connecting through hole 141 and the connecting groove 211. This allows the headlamp body 20 to be movably connected to the battery box 10, enabling the headlamp body 20 to be angled relative to the battery box 10 around the connecting axis and rotate in the up and down direction, so that the user can freely adjust the headlamp beam angle according to the lighting needs.

[0019] In practical implementation, the surface of the mounting cover 12 is provided with a display mounting slot 124 and a charging mounting slot 125 respectively. The display mounting slot 124 is used to install a power display board, and the charging mounting slot 125 is used to install an interface silicone. When in use, the user can check the remaining power through the power display board and determine whether charging is needed. At the same time, the user can open the interface silicone and charge through the charging interface. The operation is convenient, safe and reliable.

[0020] In practice, the mounting cover 12 has symmetrical button mounting slots 126 on both sides of its surface. Each of the two button mounting slots 126 is used to mount a headlamp button. In use, the user can press the headlamp button set in the button mounting slot 126 to control the headlamp on and off and switch the lighting mode.

[0021] In summary, the upper end cover of the battery box 10 is equipped with a mounting cover 12. The upper edge of the battery box 10 has a first engaging protrusion 13, and the lower edge of the mounting cover 12 has a second engaging protrusion 121. The outer side of the first engaging protrusion 13 has a first connecting buckle 131, and the inner side of the second engaging protrusion 121 has a second connecting buckle 122. The second engaging protrusion 121 is connected to the outer side of the first engaging protrusion 13. At the same time, the second connecting buckle 122 and the first connecting buckle 131 are engaged and connected. The headlamp of this utility model realizes quick installation and removal of the top cover. Users can open the top cover without tools to replace the battery or maintain the internal circuit, which improves the convenience of use and maintenance efficiency.
