[0046] As a portable lighting tool, headlamps play an important role in various nighttime or low-light environments. However, there are still some common problems with the design of headlamps in the prior art. One major problem is that the battery and circuit board are usually placed in the internal chamber of the headlamp body at the same time. Although this design protects these sensitive components to a certain extent, it also brings several drawbacks. First, because sufficient space needs to be provided for the battery and circuit board, the optimization of the size and weight of the headlamp is limited. This not only affects the portability of the headlamp, but also reduces the comfort of wearing it for a long time.

[0047] Secondly, this design may cause heat dissipation problems. Batteries generate heat during discharge, and circuit boards also generate heat during operation. When these components are closely placed in a limited space, the heat may not be effectively dissipated, affecting the performance of the headlight and the life of the components.

[0048] In addition, the close layout of the battery and the circuit board may increase the difficulty of maintenance and replacement. When the battery is exhausted or the circuit board needs to be repaired, the user may need to disassemble the entire headlamp body, which is not only time-consuming, but may also increase the maintenance cost due to the complex design. The headlamp structure provided in this application is intended to solve the above problems, so that the use scenarios of the headlamp can be expanded and the service life of the headlamp can be improved.

[0049] Reference Manual Attached Figure 1 and Figure 2 The present application provides a headlamp structure, including a headlamp body 1, a first circuit board 2, a light-emitting element and a lampshade 3.

[0050] For details, please refer to Figure 4 The headlamp body 1 has a containing chamber 10 and a first mounting position 11. The containing chamber 10 is arranged inside the headlamp body 1. The opening of the containing chamber 10 is located at the top of the headlamp body 1. The first mounting position 11 is arranged on the outer side wall of the headlamp body 1. The first mounting position 11 and the containing chamber 10 are separated from each other. The containing chamber 10 is used to install the battery 4, and the first mounting position 11 is used to install the first circuit board 2. The first circuit board 2 is powered by the battery 4, thereby realizing the effective separation and coordinated work of the battery 4 and the first circuit board 2.

[0051] The first installation position 11 and the accommodating chamber 10 are separated from each other, which not only optimizes the spatial layout but also provides a suitable installation position for the first circuit board 2. Through the physical structural separation, the heat generated by the battery 4 during operation is effectively prevented from causing adverse effects on the first circuit board 2, thereby improving the overall heat dissipation efficiency.

[0052] On the other hand, the headlights in the prior art often adopt an integrated design, which makes it difficult to replace the battery 4 and the circuit board is prone to overheating. In this embodiment, through this partitioned design, a housing chamber 10 is provided inside the headlight body 1, providing a dedicated space for the battery 4, which is convenient for installation and replacement, while ensuring the safety and stability of the battery 4, simplifying the replacement process of the battery 4, and improving the heat dissipation efficiency by optimizing the installation position of the first circuit board 2, thereby extending the service life of the headlight.

[0053] Furthermore, after the first circuit board 2 is installed in the first mounting position 11, it is powered by the battery 4 in the accommodating chamber 10, forming a simple and efficient power supply path. This design simplifies the electrical connection, reduces energy loss, and improves the stability and reliability of the headlamp, making the entire headlamp structure more compact and lightweight, while ensuring the stability and durability of the lighting function.

[0054] At the same time, the above-mentioned light-emitting elements are arranged on the first circuit board 2, and the lampshade 3 is sleeved on the headlamp body 1 from one side of the first circuit board 2, providing necessary protection for the light-emitting elements on the first circuit board 2, and forming a partial cover for the lateral peripheral wall of the headlamp body 1, thereby enhancing the durability and protection performance of the headlamp, and also optimizing the distribution and focusing of light through partial covering, thereby improving the lighting effect.

[0055] In one embodiment, based on the above embodiments, Figure 8 As shown, the lampshade 3 includes a light emitting surface 31 and a fixing surface 32 , wherein the light emitting surface 31 precisely corresponds to the light emitting element on the first circuit board 2 , thereby ensuring effective light output and maximization of lighting efficiency.

[0056] In addition, a battery through hole 320 is designed on the fixing surface 32, and the battery through hole 320 corresponds to the opening of the accommodating chamber 10, forming a channel specifically for adapting the loading and removal of the battery 4, which significantly improves the user experience. This design simplifies the battery 4 replacement process, and the user can quickly replace the battery 4 without disassembling the entire headlamp. Compared with the common structure in the prior art that requires disassembly of multiple parts to replace the battery 4, it significantly reduces the maintenance time and operation complexity. It not only improves the user experience of the headlamp, but also reduces the risk of damage caused by frequent disassembly due to its simplified maintenance process, thereby improving the durability and reliability of the headlamp.

[0057] Optionally, additional ventilation holes are designed on the fixing surface 32 of the lampshade 3 to enhance the heat dissipation effect and extend the service life of the battery 4 and the circuit board. In addition, the lampshade 3 can be made of a lighter and impact-resistant material to reduce the weight of the headlamp and improve durability.

[0058] Further, such as Figure 2As shown, the headlamp structure also includes a battery cover 52, which is connected to the fixing surface 32 of the lampshade 3 from the opening side of the accommodating chamber 10 to seal the accommodating chamber 10, thereby effectively preventing dust, moisture and other external factors that may damage the battery 4 from entering.

[0059] In addition, the design of the battery cover 52 simplifies the replacement process of the battery 4. The user only needs to remove the battery cover 52 from one side of the opening to quickly replace the battery 4 without disassembling the entire headlight, which significantly improves the safety and convenience of maintenance of the battery 4. In some embodiments, a locking assembly is provided on the battery cover 52 to ensure the stability of the battery cover 52 in a closed state and prevent accidental opening due to vibration or impact.

[0060] In one embodiment, Figure 8 As shown, the headlamp structure further includes an end cap 33, which is fixed to the fixing surface 32 of the lampshade 3. The mounting hole provided on the end cap 33 is embedded with an internal thread, so that it can be threadedly connected with the external thread of the battery cover 52, thereby simplifying the user's battery 4 installation and removal process. The user only needs to tighten or loosen the battery cover 52 to easily complete the replacement or installation of the battery 4. The whole process does not require any additional tools, which greatly improves the user experience.

[0061] Moreover, if Figure 1 As shown, a sealing ring 500 is provided between the battery cover 52 and the conductive element 51, which further enhances the sealing effect between the battery cover 52 and the end cover 33, wherein the sealing ring 500 has a certain elasticity, and when the battery cover 52 is screwed onto the end cover 33, the gap between the two is filled and sealed, thereby effectively preventing the intrusion of dust, moisture and other external substances, protecting the battery 4 and the conductive element 51 from corrosion and damage, thereby extending the service life of the battery 4 and ensuring the stable operation of the circuit.

[0062] In addition, the use of the sealing ring 500 also helps to improve the waterproof performance of the headlamp, so that it can adapt to more harsh working environments. The good seal formed between the battery cover 52 and the end cover 33 provides an additional layer of protection for the headlamp, ensuring reliable operation in wet or dusty environments.

[0063] Based on the above embodiments, Figure 4 As shown, the headlamp body 1 in the above embodiment includes a mounting assembly, an annular baffle 12 and a bottom plate 13. The annular baffle 12 is fixed on the bottom plate 13. The two together constitute a receiving chamber 10. The material, shape and other parameters of the bottom plate 13 are not limited in this embodiment, as long as it can effectively accommodate the battery 4.

[0064] In addition, the mounting assembly is disposed on the outer peripheral wall of the annular baffle 12 , and cooperates with the annular baffle 12 to form a first mounting position 11 , providing a precise and stable mounting platform for the first circuit board 2 .

[0065] It can be understood that, through the design in this embodiment, the headlamp body 1 not only physically realizes the effective separation of the battery 4 and the first circuit board 2, but also functionally realizes the independent operation of power supply and lighting control. The design of the mounting assembly makes the installation of the first circuit board 2 more convenient. At the same time, since it is located outside the annular baffle 12, it also provides good heat dissipation conditions for the first circuit board 2. On the other hand, the combination of the annular baffle 12 and the bottom plate 13 not only provides certain structural support, but also provides necessary protection for the battery 4 in the accommodating chamber 10 to prevent damage caused by falling or impact.

[0066] The form of the mounting assembly is not specifically limited in this embodiment, and the mounting assembly may have multiple fixing points for firmly fixing the first circuit board 2. These fixing points may be claws, slots or clamps to accommodate circuit boards of different sizes and shapes, ensuring that the circuit board can remain stable under various use conditions.

[0067] Optionally, the surface of the mounting component is designed with a heat dissipation portion to increase the surface area in contact with the air and improve the heat dissipation efficiency, thereby protecting the circuit board from overheating; in addition, it is possible to consider integrating a temperature sensor on the mounting component to monitor the temperature of the circuit board in real time. Of course, in other embodiments, the mounting component may also have other design forms, which are not described here one by one.

[0068] In one embodiment, based on the above embodiment, Figure 5 and Figure 6 As shown, a first electrode spring 71 is arranged at the bottom of the accommodating chamber 10, and a second electrode spring 72 is arranged on the side of the first mounting position 11 close to the opening of the accommodating chamber 10. The first electrode spring 71 is connected to the first electrode of the battery 4, and the second electrode spring 72 is connected to the second electrode of the battery 4. The first electrode spring 71 and the second electrode spring 72 are respectively electrically connected to the first circuit board 2, thereby forming a battery 4 passage for power supply.

[0069] It is understandable that this design significantly reduces the complexity of the electrical connection, which is conducive to simplifying the internal structure of the headlamp. At the same time, since the electrode spring is elastic, it can maintain stable contact with the electrode of the battery 4, and maintain the reliability of the connection even in the case of vibration or impact.

[0070] In addition, as attached Figure 7As shown, it is possible to integrate a spring mechanism in the design of the electrode spring to provide a more stable contact pressure. For details, referring to the arrangement of the second electrode spring 72, a receiving groove 720 is arranged on the headlamp body 1 to fix the spring 721 to prevent it from falling off, wherein the two ends of the spring 721 are respectively connected to the bottom of the receiving groove 720 and the second electrode spring 72, thereby providing a certain elastic effect for the second electrode spring 72. In addition, different shapes and sizes of electrode springs can be designed to adapt to batteries 4 of different types and sizes, thereby improving the versatility of the headlamp.

[0071] Among them, Figure 4 As shown, the annular baffle 12 is provided with a first via hole 120 on one side close to the bottom plate 13. The first via hole 120 can connect the first mounting position 11 and the accommodating chamber 10, thereby providing a channel for the electrical connection between the first electrode spring 71 and the first circuit board 2, simplifying and directing the path of the battery 4, reducing the length of the electrical connection, and thus reducing resistance and energy loss. In addition, in other embodiments, it can be considered to design a sealing structure around the first via hole 120 to prevent the intrusion of dust and moisture and protect the electrical connection from environmental factors.

[0072] Furthermore, Figure 3 As shown, one end of the second electrode spring 72 in the above content is welded and fixed to the first circuit board 2, and the other end is bent inward and connected to the top of the headlamp body 1. At the same time, a conductive element 51 is provided on the side of the battery cover 52 facing the accommodating chamber 10. When the battery cover 52 is covered on the accommodating chamber 10, the conductive element 51 simultaneously abuts against the second electrode and the second electrode spring 72, forming an effective electrical path, and the sealing effect of the battery cover 52 also protects the electrical connection from the influence of the external environment.

[0073] Based on the above content, this embodiment integrates the conductive element 51 into the battery cover 52, and simultaneously completes the installation and fixation of the battery 4 of the headlamp structure and the circuit connection. The battery cover 52 not only serves as a component for closing the accommodating chamber 10, but its integrated conductive element 51 also assumes the function of electrical connection, thereby reducing the connection lines inside the headlamp, reducing the complexity of the internal structure, and making the headlamp more compact. When installing the battery 4, the user only needs to put the battery 4 into the accommodating chamber 10 and cover the battery cover 52, and the conductive element 51 will then contact the second electrode spring 72 to automatically complete the circuit connection.

[0074] In one embodiment, the annular baffle 12 is designed in a circular tubular shape, and the mounting assembly includes two mounting plates 14 parallel to each other, which are symmetrically distributed on the outer periphery of the annular baffle 12, forming a unique structural layout, similar to the geometric shape of two parallel straight lines tangent to a circle, so that the ends of the two mounting plates 14 cooperate with the outer peripheral portion of the annular baffle 12 to jointly form a first mounting position 11.

[0075] At the same time, it can be seen that when the first circuit board 2 is installed in the first installation position 11, the first circuit board 2 is confined between the two mounting plates 14, ensuring the position accuracy and stability of the circuit board. In other embodiments, additional positioning features such as lugs or grooves can be designed on the mounting plate 14 to achieve more accurate positioning.

[0076] In addition, the replacement and maintenance process of the circuit board is simplified by installing the first circuit board 2 between the two mounting plates 14. Users or maintenance personnel can quickly operate the first circuit board 2 to perform necessary replacement or maintenance without disassembling the entire headlamp structure, which greatly reduces maintenance costs and time.

[0077] Furthermore, Figures 4 to 6 As shown, the annular baffle 12 and two mutually parallel mounting plates 14 together form a wiring cavity 160, thereby providing a wiring space inside the headlight structure. Among them, the outer wall of one mounting plate 14 is provided with a second mounting position 15, and the two ends of the wiring cavity 160 are connected to the second mounting position 15 and the second mounting position 15.

[0078] The second mounting position 15 is used to mount the second circuit board 61. The second circuit board 61 is connected to the second circuit board 61 through the electrical connection element 8. The electrical connection element 8 is routed through the wiring cavity 160, ensuring the stability and reliability of the connection. The wiring path of the electrical connection element 8 corresponds to the contour of the wiring cavity 160, which not only avoids the clutter and mutual interference of the lines, but also facilitates the subsequent maintenance and upgrade.

[0079] Specifically, the wiring cavity 160 naturally surrounds the periphery of the annular baffle 12, providing a continuous channel for the electrical connection element 8, optimizing the wiring path, reducing the bending and crossing of the lines, and allowing the electrical connection element 8 to fit tightly around the periphery of the annular baffle 12, reducing the required space and leaving more space for other components of the headlight.

[0080] Optionally, a wire fixing device, such as a buckle or a strap, may be provided in the wiring cavity 160 to ensure that the electrical connection element 8 is stably fixed in the wiring cavity 160. In addition, an anti-slip texture may be designed on the inner wall of the wiring cavity 160 to increase the friction between the electrical connection element 8 and the wiring cavity 160 and prevent displacement caused by vibration.

[0081] In another embodiment, different from the above embodiment, a switch element is provided on the second circuit board 61, which is used to control the relative state of the light-emitting element on the first circuit board 2 by operating the switch element, so that the user can instantly control the turning on and off of the light-emitting element. On the other hand, the design of the switch element can be extended to a variety of control functions, such as multi-mode switching, brightness adjustment, etc., which increases the applicability of the headlamp.

[0082] More specifically, Figure 7 As shown, the light-emitting element includes a first light-emitting element 91 and a second light-emitting element 92, which are respectively responsible for providing different types of lighting outputs. In order to achieve independent control of the two light-emitting elements, the switch element includes a first switch element 621 and a second switch element 622, wherein the first switch element 621 is used to control the on or off of the first light-emitting element 91, and the second switch element 622 is used to control the on or off of the second light-emitting element 92, so that the user can select an appropriate lighting mode according to different usage scenarios.

[0083] Based on the above, the outer contour of the light-emitting surface 31 is designed as a curved contour, which helps to optimize the distribution of light and reduce glare. A condenser 34 and a floodlight 35 are provided on the light-emitting surface 31 to match different types of light-emitting elements. The condenser 34 is provided corresponding to the first light-emitting element 91 to concentrate light and enhance the long-distance projection capability of the lighting; the floodlight 35 is provided corresponding to the second light-emitting element 92 to diffuse light and provide a wide lighting range.

[0084] In addition, smart sensors can be integrated into the headlight structure, such as ambient light sensors or motion sensors, to achieve automatic lighting control. For example, the brightness of the light-emitting element can be automatically turned on or adjusted according to the brightness of the surrounding environment, or the lighting mode can be automatically switched when the user's head movement is detected.

[0085] In one embodiment, Figure 1 As shown. The switch element integrated on the second circuit board 61 is physically operated by the installed mechanical button 63. In use, the user directly accesses and controls the lighting function of the headlight through the mechanical button 63. The design of the mechanical button 63 can include various patterns, such as icons indicating the on / off state, symbols for brightness adjustment, or logos for spotlight / floodlight modes. Through the dual feedback of touch and vision, the user can operate more accurately and reduce the possibility of misoperation.

[0086] In addition to traditional mechanical buttons 63, it is also possible to consider using buttons made of flexible materials, which can be integrated into the surface of the headlight to provide a seamless appearance and waterproof performance. And they can be equipped with backlight patterns to adapt to different usage environments.

[0087] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
