Description

Technical Field

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

[0002] Headlamps, as a type of portable lighting tool that can be worn on the head, are widely used in various scenarios such as nighttime outdoor work, wilderness exploration, camping activities, and mining, thanks to their core advantage of freeing up the hands. They have become key equipment to meet the lighting needs of specific scenarios.

[0003] In existing technologies, the mainstream design of headlamps is mostly an integrated structure, where the core lighting module and the power supply module are directly fixedly connected to the same headlamp strip or support bracket. This integrated structure has significant limitations and maintenance drawbacks in practical use: when the lighting module needs repair or replacement due to circuit faults, damaged LEDs, or other issues, because the lighting module, power supply module, and headlamp strip are fixedly connected, the operator must remove the entire headlamp from the head, and may even need to disassemble the connection between the power supply module and the headlamp strip before addressing the faulty lighting module. This not only involves cumbersome procedures but also significantly prolongs repair time, affecting the headlamp's normal operating efficiency.

[0004] Even though some headlamp products adopt a separate design where the lighting module and power supply module are separate, the assembly and connection structure between the modules still has design flaws. These separate headlamps often rely on complex connection methods such as screw fastening and multiple sets of nested clips to fix the lighting module to the support structure. Disassembly requires special tools to unscrew the screws or forcibly separate the clips. Not only is the disassembly and assembly process time-consuming and laborious, but repeated disassembly and assembly can easily lead to structural damage such as stripped screws and broken clips, which seriously shortens the overall lifespan of the headlamp and also reduces the structural stability of the headlamp during use.

[0005] Given the aforementioned defects in the structural design of existing headlamps, how to achieve convenient disassembly and stable assembly of the lighting module, simplify maintenance procedures, and extend the service life of the equipment has become a pressing technical problem to be solved in the current headlamp product design field. Therefore, developing a modular detachable headlamp has significant practical application value and market demand. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 In this embodiment of the utility model, a modular detachable headlamp has an overall structure including a headlamp strip 1, a first connector 2, a second connector 3, a power supply module 4, and a lighting module 5. The various parts cooperate with each other to achieve convenient wearing and stable lighting functions.

[0033] The headlamp strap 1 is made of a flexible strip material, and an adjustable headband can also be used to accommodate different head circumferences, making it easy to stably wear the entire headlamp on the user's head. The first connector 2 and the second connector 3 are both connected to the headlamp strap 1, and are spaced apart along the length of the headlamp strap 1. The first connector 2 is located at the rear of the headlamp strap 1, and the second connector 3 is located at the front of the headlamp strap 1. This layout allows the power supply module 4 mounted on the first connector 2 and the lighting module 5 mounted on the second connector 3 to form a back-to-foreground distribution, which conforms to the wearing habits of the human head and avoids mutual interference.

[0034] The power supply module 4 is mounted on the first connector 2, and can house energy storage components such as batteries to provide the electrical energy required for the lighting module 5 to operate. The lighting module 5 is mounted on the second connector 3, and is electrically connected to the power supply module 4 via wires to obtain electrical energy and convert it into lighting light. Because the power supply module 4 and lighting module 5 adopt this separate design and are installed at different positions on the headlamp strip 1, not only is the weight burden on any single position reduced, improving wearing comfort, but also, if one module malfunctions, only the faulty module needs to be addressed, without the need for complete disassembly or replacement, greatly reducing maintenance costs and operational complexity.

[0035] The second connector 3 is provided with an assembly groove 6, which is specifically used to accommodate and fix the bottom of the lighting module 5. Each of the two inner walls of the assembly groove 6 has a spring piece 7, made of a material with good elastic deformation capability, capable of deforming under force and returning to its original shape after the external force is removed. The bottom of the lighting module 5 can be detachably fitted into the groove through the slot at the upper end of the assembly groove 6, and each of its two outer walls has a protruding abutment part 8. When the bottom of the lighting module 5 is inserted into the assembly groove 6, the abutment part 8 contacts and presses against the spring piece 7, while the spring piece 7 applies a reverse elastic force to the abutment part 8, thereby stably locking the lighting module 5 in the assembly groove 6. When it is necessary to remove the lighting module 5, simply apply a certain pulling force outwards to make the abutment part 8 overcome the elastic force of the spring piece 7, and the lighting module 5 can be removed from the assembly groove 6. The entire process does not require any tools, achieving rapid assembly and disassembly of the lighting module 5.

[0036] Specifically, the structure of the second connector 3 includes a base plate 9, a front plate 10, a rear plate 11, a left side plate 12, and a right side plate 13. These five parts are integrally formed and together enclose the aforementioned mounting groove 6. The rear plate 11 is fixedly connected to the headlamp strip 1, thereby securely mounting the entire second connector 3 onto the headlamp strip 1. A spring piece 7 is fixed on the inner wall of each of the left side plate 12 and the right side plate 13. The spring piece 7 extends along the depth direction of the mounting groove 6, and its free end protrudes towards the inside of the mounting groove 6. This structural design ensures that the spring piece 7 forms an effective and stable contact with the abutment part 8 at the bottom of the lighting module 5.

[0037] To further enhance the stability of the fit between the lighting module 5 and the second connector 3, a groove 14 is provided at the bottom of the lighting module 5. The shape and size of the groove 14 are adapted to the base plate 9. When the lighting module 5 is installed, the base plate 9 can be precisely inserted into the groove 14, forming a tight mating fit. At the same time, a slot 15 is also provided at the bottom of the lighting module 5. The slot 15 is adapted to the front plate 10 and communicates with the groove 14. During installation, the front plate 10 can be inserted into the slot 15 to form a plug-in fit. Through the mating of the groove 14 and the base plate 9, the plug-in of the slot 15 and the front plate 10, and the elastic pressing of the spring piece 7 and the abutment part 8, the lighting module 5 can be fixed from multiple dimensions, effectively preventing it from loosening or shaking during use.

[0038] The front end of the lighting module 5 is the lighting end 16, which integrates a light source component for emitting lighting light. When the bottom end of the lighting module 5 is inserted into the front panel 10 through the slot 15, the lighting end 16 will naturally protrude from the outside of the front panel 10. This setting can prevent the front panel 10 from blocking the light, ensuring that the lighting range is not affected, while also ensuring the cleanliness of the appearance.

[0039] The groove 14 is recessed along the center of the bottom end of the lighting module 5, which makes the left and right sides of the lighting module 5 form symmetrical abutment arms 17, and the abutment part 8 protrudes on the outer wall of the abutment arm 17. At the same time, the bottom plate 9 is provided with a step between the left side plate 12 and the right side plate 13. The height of the step is adapted to the thickness of the bottom end of the abutment arm 17. When the lighting module 5 is installed in place, the bottom end of the abutment arm 17 will be placed on the step, which not only supports the abutment arm 17, but also makes the abutment part 8 and the spring piece 7 in the best abutment position, further enhancing the tightness of the fit between the two.

[0040] The right side of the lighting module 5 is provided with a terminal 18, which is connected to the output terminal of the power supply module 4 through a wire to achieve electrical conduction between the two. In order to avoid interference between the right side plate 13 and the terminal 18 and the wire, a clearance notch 19 is provided at the upper end of the right side plate 13. The shape of the clearance notch 19 is adapted to the shape of the terminal 18, and its size is slightly larger than that of the terminal 18, so that the terminal 18 can pass through the notch smoothly. At the same time, sufficient space is reserved for the arrangement of the wire to ensure that the wire is not damaged due to compression.

[0041] In summary, the elastic fit between the spring piece 7 in the mounting slot 6 of the second connector 3 and the bottom abutment part 8 of the lighting module 5 allows for the installation and removal of the lighting module 5 without tools, simplifying the operation process and improving the efficiency of repairing or replacing the lighting module 5. The front plate 10 and the groove 14 and slot 15 of the lighting module 5 form a multi-dimensional fit. Combined with the elastic pressure of the spring piece 7 and the abutment part 8 and the support of the step position on the abutment arm 17, the lighting module 5 is not easy to loosen or shake after installation, ensuring the structural stability during use. The split design allows the power supply module 4 and the lighting module 5 to be maintained separately. When one module fails, it is not necessary to disassemble or replace the entire headlamp, reducing unnecessary component waste and lowering maintenance costs.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
