Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a headlamp with an adjustable mounting structure. Background Technology

[0002] Headlamps, as portable lighting tools, are widely used in outdoor activities, industrial operations, emergency rescue, and other situations. Traditional headlamps are mostly mounted with fixed headbands or rigid brackets, and their beam angle is usually not adjustable or has only a limited adjustment range, making it difficult to meet the lighting needs of different usage scenarios.

[0003] Currently, some headlamp products on the market attempt to achieve angle adjustment through hinged structures, but the following problems still exist: First, the adjustment structure is complex and inconvenient to operate; second, there is a lack of a reliable positioning mechanism after adjustment, which can easily lead to loosening or rebound during use; and third, the structure is not well sealed, affecting the reliability of use in harsh environments.

[0004] In addition, existing headlamps often do not fully consider the compactness and stability between the mounting bracket and the lamp body in their structural design, resulting in a large overall size, inconvenience in carrying, or susceptibility to structural damage under external forces such as drops and vibrations.

[0005] Therefore, how to design a headlamp mounting structure that is simple in structure, easy to adjust, reliable in positioning, and has good sealing performance has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] This invention addresses the problems of inconvenient adjustment, unreliable positioning, and poor overall sealing in existing headlamps, providing a headlamp with a compact structure, flexible adjustment, stable locking, and good environmental adaptability. Its purpose is to achieve rapid, multi-level adjustment and reliable fixation of the illumination angle by optimizing the integrated design of the installation structure and the lamp body, while simultaneously improving the overall sealing and structural strength to meet the lighting needs of complex usage scenarios.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An adjustable-angle headlamp includes a lamp housing, an illumination module disposed at the front of the lamp housing, a power module and a control module disposed inside the lamp housing, and a mounting structure disposed at the bottom of the lamp housing. The mounting structure includes a bottom cover connected to the bottom of the lamp housing and a mounting bracket rotatably connected to the bottom cover. A limiting fit structure is provided between the mounting bracket and the bottom cover for locking the mounting bracket in at least one rotational position.

[0008] Furthermore, the mounting bracket is hinged to the bottom cover via at least two hinge seats; the limiting fit structure includes a limiting part disposed on the mounting bracket and a limiting seat disposed on the bottom cover and cooperating with the limiting part, wherein the limiting part and the limiting seat are locked together by a slot structure.

[0009] Furthermore, the mounting bracket is provided with multiple mounting holes and / or mounting slots.

[0010] Furthermore, the lighting module includes a first light source module as a focused light source and a second light source module as a floodlight source. The first light source module is provided with a circular lens, and the second light source module is provided with an elliptical lens.

[0011] Furthermore, the second light source module includes a COB light source and a COB ring surrounding the COB light source; the first light source module is encapsulated by an aluminum head ring, and the COB ring is installed on the upper cover inside the lamp housing by a detachable snap-fit ​​structure.

[0012] Furthermore, the lamp housing is made of aluminum with an inner top cover that fits into the bottom cover, and a sealing gasket is provided between them.

[0013] Furthermore, aluminum sealing rings are provided between the aluminum head ring and the lamp housing or the top cover, and between the COB ring and the lamp housing or the top cover.

[0014] Furthermore, the control module includes a circuit board on which a control circuit is integrated; the bottom cover is provided with at least one control button and a charging interface electrically connected to the control module.

[0015] Furthermore, the power module is a rechargeable lithium-ion battery, which is connected to the charging interface through the control module; the bottom or side of the lamp housing is also provided with a charging status indicator light connected to the control module.

[0016] Furthermore, the overall structure of the lamp housing is configured to withstand a drop impact of at least 1 meter, and the rotating joint of the mounting bracket is configured to withstand at least 1,500 rotation tests.

[0017] Compared with the prior art, the present invention has the following significant advantages: 1. Convenient adjustment and reliable positioning: Through the combination design of hinge and limit structure, users can easily adjust the headlamp beam angle with one hand, and can achieve "click" locking at multiple preset positions, effectively avoiding the problem of lamp head sagging or angle deviation caused by vibration and shaking during use, thus improving lighting stability and user experience.

[0018] 2. Compact structure and strong versatility: The mounting bracket and lamp housing base are integrated into one design, resulting in a compact overall size. Multiple mounting holes on the bracket allow for flexible installation on various surfaces, greatly expanding its application scenarios.

[0019] 3. Excellent sealing performance: Through the synergistic effect of the internal sealing gasket and the external multiple aluminum sealing rings, an effective sealing protection is formed at the key joints of the lamp housing and the interface of the optical components, which significantly improves the product's dustproof and waterproof capabilities (such as meeting specific IP ratings) and enhances its reliability in harsh environments such as humid and dusty conditions.

[0020] 4. Easy maintenance and high durability: Key optical components such as the COB ring adopt detachable snap-fit ​​connections, facilitating cleaning or replacement. The overall structure, especially the aluminum housing and reinforced joint design, enables it to withstand higher mechanical shocks (such as drops) and more frequent angle adjustments, extending the product's lifespan.

[0021] 5. Excellent heat dissipation and safety: The aluminum casing is not only strong but also has good thermal conductivity, which helps dissipate heat from the LED light source. Meanwhile, the integrated control module has complete battery charging and discharging protection circuits, improving electrical safety.

[0022] In summary, through systematic structural innovation, this utility model significantly improves the overall performance of the headlamp in terms of angle adjustment, environmental adaptability, structural strength, and ease of use while ensuring its basic lighting function, and has high market application value.

[0031] The technical solution of this utility model will be described in detail and completely below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and not for limiting it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Please see Figures 1 to 8 This utility model provides a headlamp, and more particularly an aluminum-cased headlamp with a mounting structure that is adjustable at multiple angles and can be reliably locked.

[0033] like Figure 1 and Figure 2 As shown in the overall perspective view, the headlamp mainly includes a lamp housing 1 as the main supporting structure. In this embodiment, the lamp housing 1 is preferably made of aluminum alloy material through extrusion or die casting and subjected to surface anodizing treatment, which ensures both lightweight and high strength, as well as good heat dissipation and corrosion resistance. The lamp housing 1 has a generally square and round streamlined structure, with the front end being the light-emitting part and the rear end and bottom being the mounting and supporting parts.

[0034] The lighting module 2 is integrated into the front end of the lamp housing 1. Specifically, as shown... Figures 1 to 8As shown, the lighting module 2 adopts a zoned lighting design, including a first light source module 21 as a focused light source and a second light source module 22 as a floodlight source. The first light source module 21 is composed of a high-efficiency LED panel 211, with a circular lens 23 pressed in front of it. This lens 23 is preferably made of PMMA or optical-grade PC material to focus the light and form a long-range beam. The second light source module 22 uses a COB (Chip-on-Board) integrated light source as the COB light source 221, which has a large luminous surface and provides soft and uniform light. A COB ring 222 is provided around the COB light source 221. This COB ring 222 is preferably made of ABS material and may have a reflective coating to constrain and guide the floodlight. An elliptical lens 24 is covered in front of the COB ring 222. This lens 24 can be made of a diffusing material to make the floodlight spot softer and cover a wider area. This design of separating the focused and floodlight sources allows users to flexibly switch or combine them according to different usage scenarios (such as long-distance search and close-range operation), greatly improving the practicality of the lighting function.

[0035] The structural packaging of the first light source module 21 is completed through an aluminum head ring 11. For example... Figure 7 As shown, the aluminum head ring 11 is securely connected to the front end of the lamp housing 1 or an internal aluminum base 13 via a threaded connection, reliably pressing and fixing the circular lens 23 onto the bottom cover 51. To ensure waterproofing and dustproofing, a first annular aluminum sealing ring 71 is provided on the mating end face of the aluminum head ring 11 and the lamp housing 1 (or aluminum base 13); and a second aluminum sealing ring 72 is provided between the COB ring 222 and the internal structure of the lamp housing 1. These aluminum sealing rings undergo elastic deformation under the action of the fastening force, filling the microscopic gaps and forming an effective first sealing barrier.

[0036] The bottom of the lamp housing 1 is sealed by a bottom cover 51. The bottom cover 51 is connected to the lamp housing 1 by screws or clips. To improve the overall sealing rating (e.g., to IPX4 or higher), a conformal top cover 12 is also provided inside the lamp housing 1. The top cover 12 and the bottom cover 51 together form a sealed inner cavity for housing electronic components. Between the mating surfaces of the top cover 12 and the bottom cover 51, an annular sealing gasket 6 is provided. This sealing gasket 6 is preferably made of rubber or silicone material, forming a second critical sealing barrier. This double-layer housing (main housing + inner cavity cover) design, combined with multiple sealing rings, significantly enhances the reliability of the headlamp in harsh environments such as rain and dust.

[0037] One of the core innovations of this utility model lies in its mounting structure 5. The mounting structure 5 mainly includes a bottom cover 51 fixed to the bottom of the lamp housing 1, and a mounting bracket 52 that can rotate relative to the bottom cover 51. The mounting bracket 52 is preferably made of high-strength engineering plastic (such as PC+ABS) or metal, and its two ends are hinged to corresponding pivots on the bottom cover 51 via two hinge seats 53. This allows the mounting bracket 52 to rotate freely around the hinge axis within a certain angle range (e.g., 0-120 degrees), thereby flexibly adjusting the headlamp's beam angle.

[0038] More importantly, to reliably fix the rotation angle and prevent the lamp head from sagging due to vibration during use, this invention features a sophisticated limiting and matching structure. Specifically, as shown in... Figure 4 As shown, a raised limiting seat 54 (such as a wedge or tooth) is provided in the middle of the base 51 or near the hinge point. Correspondingly, one or more matching limiting parts 55 (such as grooves or teeth) are provided on the mounting bracket 52. When the user rotates the mounting bracket 52 to a specific angle, the limiting part 55 aligns with a limiting seat 54 and embeds itself in it under the action of elastic force, forming a "click" engagement to achieve mechanical self-locking. The user needs to apply a certain torsional force again to disengage the limiting part 55 for angle adjustment. This design provides clear tactile feedback and multi-position stable locking. The mounting bracket 52 itself is designed with multiple mounting holes 521 and mounting slots 522, which can be used to thread headbands, fix buckles to safety helmets, or connect other expansion accessories, making it highly versatile.

[0039] The internal structure of xi, after removing the bottom cover 51 and the top cover 12, reveals efficient use of internal space. A control module 4, its core being a circuit board 41, is fixed within the internal cavity. The circuit board 41 integrates a microcontroller, drive circuitry, protection circuitry, etc. Figure 3 and Figure 6 As shown, two independent control buttons 8 are provided on the bottom cover 51, used to control the focusing module and the floodlight module respectively. Through different operations such as tapping and long-pressing, functions such as power on / off, brightness adjustment (e.g., high / low), mode switching (e.g., white light / red light), and Turbo instantaneous high beam can be achieved. A charging port 9 is also integrated on the bottom cover 51; in this embodiment, a USB Type-C interface is preferably used, and a waterproof plug is provided. A charging status indicator 10 (e.g., a red / blue dual-color LED) is located near the control buttons 8 to visually display the charging status.

[0040] Power is supplied by a rechargeable lithium-ion battery 3, with specifications such as model 651730, 3.7V, 300mAh. Battery 3 is securely housed in a dedicated slot within the cavity and connected to circuit board 41 via wires. Control module 4 possesses comprehensive power management functions, including charging management, overcharge and over-discharge protection, and short-circuit protection, ensuring safe operation.

[0041] In terms of structural durability, this invention has also given full consideration to the following aspects. The aluminum housing itself has good impact resistance. The hinge joint of the mounting bracket 52 is reinforced, and its rotational life has been tested to exceed 1500 cycles. The entire lamp structure can withstand multiple impact tests from a drop of 1 meter onto a hard ground without damaging its core functions, meeting the stringent durability requirements of outdoor and industrial applications.

[0042] In summary, this specific embodiment details an innovative, fully functional, and robust headlamp. Its multi-position adjustable mounting bracket structure solves the problems of inconvenient angle adjustment and easy loosening in traditional headlamps; its separate focusing and floodlighting optical system provides a more professional lighting solution; its multi-layer sealing design significantly improves environmental adaptability; and its compact modular layout balances functionality and reliability. Those skilled in the art will fully understand and implement this invention based on the above description.

[0043] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
