Description

Technical Field

[0001] This utility model relates to the field of headlamp technology, and in particular to a simple headlamp with a lamp head that is easy to quickly disassemble. Background Technology

[0002] To meet users' needs in different scenarios, existing technologies have explored headlamps with replaceable lamp heads. For example, a headlamp with a detachable lamp head, as disclosed in Utility Model Patent Publication No. CN206522637U, includes a lamp holder, a lamp head body, and a power supply. The lamp holder has an arc-shaped mounting plate and an adapter socket. The lamp head body and the socket are connected via a plug-in connection, and the socket is electrically connected to the power supply. The mounting plate and the power supply are connected by an elastic strap. This design allows the lamp head body to change the light intensity by rotating the adjustment ring, and because the socket and mounting plate are adapter-connected, the lamp holder can be rotated to adjust the lamp head's beam angle. When the power supply is depleted, the lamp head body can be detached and plugged into an adapter. He can continue to use it on the power source; for example, a detachable headlamp device with utility model patent authorization announcement number CN213576904U consists of a lamp head and a headband assembly; the bottom end of the lamp holder of the lamp head is provided with a connector, the lamp holder holds the lamp cover housing, the lamp cover housing is provided with a first lighting mechanism and a second lighting mechanism, and the lamp cover housing is provided with a first light-transmitting sheet and a second light-transmitting sheet on both sides respectively; the headband assembly includes a connecting plate, a battery box and a headband, the connecting plate is provided with a docking seat, the headband is connected to both sides of the connecting plate, the battery box is connected to the headband, and the assembly and disassembly of the lamp head and headband assembly are completed by rotating and fixing the connector and the docking seat, so that different lighting mechanisms can be selected according to different scene requirements.

[0003] However, through in-depth research and practical application, the inventors discovered certain defects in the existing connection structures of these detachable lamp heads. In actual use, when the headband assembly is worn on the user's head, the user cannot directly see the connection structure on the headband. This means that when assembling the lamp head, the user needs to spend a certain amount of time aligning the connection parts, especially in low-light environments. This operation becomes even more difficult, greatly affecting the efficiency of lamp head replacement and failing to meet the user's need for quick lamp head replacement in emergency situations. For example, during outdoor exploration, if the headlamp suddenly runs out of power, the user needs to quickly replace the lamp head in the dark to maintain illumination. At this time, the problem of difficult alignment of the existing headlamp connection structure becomes prominent, which may threaten the user's safety. In nighttime work scenarios, the long time required to replace the lamp head will also delay the work progress.

[0004] Therefore, in order to solve the above-mentioned technical problems and improve the convenience of headlamps in actual use, it is necessary to propose an improved technical solution to optimize the connection structure of the detachable lamp head, so as to realize the lamp head replacement operation quickly and accurately without complicated alignment, and meet the user's needs for efficient lighting in various scenarios.

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a simple headlamp with easy and quick disassembly of the lamp head includes a lamp head assembly 10 for generating a light source and a headband assembly 20 for fixing to the head. The back of the lamp head assembly 10 is provided with an inverted U-shaped plug 30, and the headband assembly 20 is provided with a flat socket 21 with a closed-loop structure. The flat socket 21 has a flat insertion hole 22 that passes through its upper and lower ends. One side of the inverted U-shaped plug 30 is inserted into the flat insertion hole 22 along the top of the flat socket 21, thereby positioning and mounting the lamp head assembly 10 on the flat socket 21. The lower end of the inverted U-shaped plug 30 is also provided with a blocking edge 31, which is used to abut against the lower end of the flat socket 21 to achieve the snap-fit ​​fixation between the inverted U-shaped plug 30 and the flat socket 21.

[0028] In the above technical solution, during installation, the user only needs to insert one side of the inverted U-shaped plug 30 along the top of the flat socket 21 directly into the flat socket 22 that runs through the upper and lower ends to initially position the lamp head assembly 10 on the flat socket 21. At this time, the blocking edge 31 at the lower end of the inverted U-shaped plug 30 will abut against the lower end of the flat socket 21. Through the snap-fit ​​between the blocking edge 31 and the lower end of the flat socket 21, the lamp head assembly 10 and the headband assembly 20 are firmly fixed. During disassembly, simply lift the lamp head assembly 10 upwards. Under a large force, the blocking edge 31 will disengage from the lower end of the flat socket 21, and the inverted U-shaped plug 30 can be pulled out from the flat socket 22, thereby quickly separating the lamp head assembly 10 and the headband assembly 20.

[0029] This design significantly enhances the ease of use of the headlamp. Users do not need precise alignment of the connection structure; they can easily install and remove the lamp head with a simple plug-and-play action. Even when the headband assembly 20 is worn on the head, visibility is obstructed, or lighting conditions are dim, operation is quick and efficient, effectively saving time when replacing the lamp head and improving emergency response efficiency. Furthermore, its simple structure reduces manufacturing costs and minimizes potential malfunctions caused by complex structures, improving product reliability and durability. Users can quickly replace multiple lamp heads according to different lighting needs. The stable locking mechanism between the inverted U-shaped plug 30 and the flat socket 21 ensures the headlamp will not easily detach during use, making it better suited for various scenarios such as outdoor adventures and nighttime work, providing users with a more efficient and reliable lighting experience.

[0030] Furthermore, the design of the flat socket 21, which fits snugly against the user's forehead, further optimizes the user's operating experience and usability. When the user wears the headlamp, the flat socket 21 fits snugly against the forehead, allowing the user to accurately sense the position of the flat socket 22 through tactile feedback. When installing the lamp head assembly 10, there is no need to bend down or rely on additional lighting for observation; the insertion angle and position of the inverted U-shaped plug 30 can be quickly adjusted solely by tactile feedback. Even in complete darkness or in adverse environments with obstructed vision, lamp head replacement can be completed efficiently, greatly improving the convenience of blind installation. At the same time, the flat socket 21, which fits snugly against the forehead, provides more stable support for the headlamp during use, reducing headlamp displacement caused by head shaking. Combined with the snap-fit ​​structure between the inverted U-shaped plug 30 and the flat socket 21, this provides double protection for the headlamp's stability, preventing loosening from affecting the lighting effect.

[0031] Please see Figure 3-4 Based on the above technical solution, it is further proposed that a widened chamfer (not shown in the figure) be provided on the upper edge of the flat socket 22. This can automatically guide the plug-in when it is inserted into the inverted U-shaped plug-in of the lamp holder assembly 10, reducing the difficulty for the user to find the insertion position.

[0032] Please see Figure 4-5Based on the above technical solution, a further inverted U-shaped plug 30 is proposed, comprising a fixing plate 32, a plug plate 33, and a bend 34 connecting the upper edges of the fixing plate 32 and the plug plate 33. The fixing plate 32 and the plug plate 33 are spaced together. The fixing plate 32 is fixed to the back of the lamp head assembly 10, and the plug plate 33 is used to insert into the flat socket 22. Its structural design is simple. Among them, the blocking edge 31 is formed on the lower edge of the plug plate 33, and the blocking edge 31 extends towards the fixing plate 32. After the plug plate 33 is inserted into the flat socket 22, its blocking edge 31 can protrude from below the flat socket 22 and abut against the lower end of the flat socket 21. This structure can form a stable snap-fit ​​structure, which can ensure stable lighting of the headlamp even in outdoor adventures or high-intensity work scenarios with severe shaking and bumps.

[0033] Furthermore, the thickness of the flat socket 22 is greater than or equal to the combined thickness of the insert plate 33 and the blocking edge 31, which ensures the smooth insertion of the inverted U-shaped plug and enhances the connection stability through a tight fit, preventing looseness and wobbling. The distance between the fixing plate 32 and the insert plate 33 is matched with the distance from the front side of the flat socket 22 to the front side of the flat socket 21, allowing the inverted U-shaped plug and the flat socket 21 to fit precisely, further improving the compactness and reliability of the overall structure. Both the inverted U-shaped plug 30 and the flat socket 21 are made of metal. With the good wear resistance, corrosion resistance and high hardness of metal, they are not easily deformed, damaged or oxidized even after frequent plugging and unplugging operations and harsh environmental corrosion, greatly extending the service life of the headlamp.

[0034] Please see Figure 4-5 Based on the above technical solution, the lamp head assembly 10 is further proposed to include a main body 11 and a lamp cover 12 disposed at the front end of the main body 11. A lithium battery 13 is disposed inside the main body 11, and a charging interface 14 and a control switch 15 are disposed outside the main body 11. A light source 16 is disposed inside the lamp cover 12. The lithium battery 13 is provided with a charging and discharging circuit 17. The charging end of the charging and discharging circuit 17 is electrically connected to the charging interface 14, and the discharging end of the charging and discharging circuit 17 is electrically connected to the light source 16 through the control switch 15. The charging and discharging function is closely integrated with the lighting function, reducing the external wiring connection, reducing the risk of headlamp failure due to wiring faults, improving the overall reliability of the product, and providing users with a more efficient, convenient and stable lighting experience.

[0035] Please see Figure 2-4Based on the above technical solution, the headband assembly 20 further includes an elastic band 24 and fasteners 25 connected to both ends of the elastic band 24. The fasteners 25 are formed on both sides of the flat socket 21, and a cushioning pad 26 for supporting the forehead is also provided on the back of the flat socket 21. The elastic band 24, with its elasticity and stretching properties, can adaptively adjust according to the user's head circumference when worn. By applying even tension to both sides, it tightly fits the flat socket 21 against the forehead, ensuring that the flat socket 21 and the inverted U-shaped plug of the lamp head assembly 10 always maintain precise alignment and tight connection, even during vigorous exercise. During frequent head movements, the lamp head assembly 10 can be effectively prevented from loosening or falling off due to shaking, ensuring the continuity and stability of lighting. In addition, the cushioning pad 26 on the back of the flat socket 21 can not only effectively buffer the pressure when the elastic band 24 is pulled, avoiding pressure on the forehead, but also fill the tiny gap between the flat socket 21 and the forehead with soft material, further enhancing the stability of the flat socket 21. This allows users to maintain a comfortable experience while enjoying stable and reliable lighting effects during long-term wear, making it especially suitable for outdoor adventures, night work, and other scenarios with high stability requirements.

[0036] Please see Figure 1-3 Based on the above technical solution, it is further proposed that the flat socket 21 is adapted to the arc structure in front of the forehead, and the inverted U-shaped plug 30 is adapted to the arc structure of the flat socket 21; so that the headlamp is subjected to more even force when worn, effectively reducing the local pressure feeling. At the same time, the tight fit enhances the stability of the headlamp, reduces displacement caused by head shaking, and ensures that the lighting direction is always accurate and controllable.

[0037] 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.
