[0032] 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.

[0033] Example

[0034] like Figure 1-8 As shown, an embodiment of the present invention provides a multifunctional flashlight, including a flashlight body shell 1, a control module 2 disposed inside the flashlight body shell 1, a lamp head 3 at one end of the flashlight body shell 1, and a first light-emitting component 4 and a second light-emitting component 5 disposed on the lamp head 3 with opposite lighting directions.

[0035] By integrating two sets of reverse-configured light-emitting components into a single lamp head, the function of integrating two different lighting modes (such as spotlight and floodlight) into one flashlight is realized, which greatly improves the product's portability and the wide range of applicable scenarios.

[0036] like Figure 1-8 As shown, in some embodiments, the lamp head 3 includes a lamp plate holder 31 threaded onto one end of the flashlight body shell 1. A threaded enclosure 32 is provided on one side of the lamp plate holder 31. The first light-emitting component 4 is disposed on one side of the lamp plate holder 31 and located inside the threaded enclosure 32. The second light-emitting component 5 is disposed on the other side of the lamp plate holder 31.

[0037] The lamp holder 31 serves as the core carrier. One side of it is connected and fixed to the main body shell 1 of the flashlight via threads, while the other side is constructed into an installation chamber via a threaded enclosure 32. The first light-emitting component 4 is integrated into this chamber, while the second light-emitting component 5 is directly installed on the back of the lamp holder 31, achieving physical isolation and electrical interconnection between the two components.

[0038] The lamp plate holder 31 is detachably fixed to the main body shell through a threaded connection, which facilitates internal maintenance and assembly; the threaded enclosure 32 not only provides installation and protection space for the first light-emitting component 4, but also provides an interface foundation for the installation of its external optical components. The structure is compact and the functional areas are clearly defined.

[0039] like Figure 1-8 As shown, in some embodiments, the first light-emitting component 4 includes a first lamp panel 41, and a small reflector 42, a large reflector 43, and a condenser lens 44 sequentially disposed on one side of the first lamp panel 41.

[0040] The lamp plate holder 31 has two inner and outer grooves on one side for mounting the small reflector bowl 42 and the large reflector bowl 43. The inner ring of the large reflector bowl 43 fits into the outer ring of the small reflector bowl 42. The light emitted by the first lamp plate 41 is first initially focused by the small reflector bowl 42, and then further reflected and constrained by the large reflector bowl 43 to form a more concentrated beam. Finally, it is refracted by the focusing lens 44 and the beam divergence angle is compressed, thereby achieving excellent long-range performance.

[0041] The combination of a small reflector bowl 42 and a large reflector bowl 43 enables the collection and pre-focusing of light in stages. Combined with a condenser lens 44 for final adjustment, the light is effectively converged to form a bright central spot and a strong long-range lighting effect.

[0042] like Figure 1-8 As shown, in some embodiments, the second light-emitting component 5 includes a second lamp panel 51 and a lampshade 52 disposed on one side of the second lamp panel 51, wherein the side of the lampshade 52 away from the second lamp panel 51 is tapered.

[0043] The second lamp panel 51 is a COB lamp panel. The light emitted by it enters the inner wall of the conical lampshade 52. After multiple refractions and diffuse reflections, the directionality of the light is destroyed, so that the light is emitted uniformly and at a large angle from the conical surface of the lampshade 52, forming a floodlight field.

[0044] The conical lampshade 52 can diffuse the light emitted by the second lamp panel 51 over a large angle, forming a uniform and wide lighting area, perfectly achieving large-area floodlighting, suitable for close-range work or ambient lighting.

[0045] like Figure 1-8 As shown, in some embodiments, the flashlight body shell 1 includes a battery compartment shell 11 and a control compartment shell 12 threaded onto one end of the battery compartment shell 11. A first sealing ring 13 is also provided between the battery compartment shell 11 and the control compartment shell 12. The end of the control compartment shell 12 away from the battery compartment shell 11 is threaded onto one side of the lamp plate holder 31.

[0046] The battery compartment housing 11, the control compartment housing 12, and the lamp holder 31 are connected end to end by threads to form a complete flashlight body. The first sealing ring 13 is compressed in the connection gap between the battery compartment housing 11 and the control compartment housing 12, forming a waterproof barrier. The split housing design separates the battery compartment housing 11 from the control compartment housing 12, which facilitates the professional design and independent production and assembly of each component. The threaded connection with the first sealing ring 13 ensures the structural strength of the connection points of each component and the overall waterproof sealing performance.

[0047] like Figure 1-8As shown, in some embodiments, one end of the control compartment housing 12 is further provided with a stepped portion 121 that abuts against the side of the lampshade 52 away from the second lamp plate 51, and a second sealing ring 14 is further provided between the stepped portion 121 and the lampshade 52.

[0048] When the lamp holder 31 is screwed onto the control chamber housing 12, it will push the second light-emitting component 5 to move towards the control chamber housing 12, so that the end face of the lamp cover 52 abuts against the step portion 121, and at the same time, the inside of the lamp cover 52 is tightly pressed against the second sealing ring 14, and the seal is achieved by compression deformation.

[0049] The step portion 121 provides axial positioning and support for the conical lampshade 52, ensuring its positional stability; the second sealing ring 14 is compressed between the step portion 121 and the lampshade 52, effectively preventing moisture and dust from intruding into the control chamber housing 12 from the side of the second light-emitting component 5.

[0050] like Figure 1-8 As shown, in some embodiments, a reflective sleeve 6 is also included. The outer and inner sides of the reflective sleeve 6 are threadedly connected to the threaded enclosure 32 and the large reflective cup 43, respectively. A third sealing ring 61 is also provided between the reflective sleeve 6 and the threaded enclosure 32. A limiting part 62 is also provided inside the reflective sleeve 6. The limiting part 62 is engaged with the outer edge of the condensing lens 44. A fourth sealing ring 63 is also provided between the limiting part 62 and the condensing lens 44.

[0051] The reflector sleeve 6 locks the entire optical system within the threaded enclosure 32 of the lamp plate holder 31 through internal and external threads; its internal limiting part 62 locks the condenser lens 44 from the rear to prevent it from loosening; the third sealing ring 61 and the fourth sealing ring 63 respectively isolate the external environment and other cavities inside the flashlight body shell 1.

[0052] The reflector sleeve 6 serves as the core connector, simultaneously fixing the internal optical components (large reflector bowl 43, condenser lens 44) and the external structure (threaded enclosure 32). It achieves independent sealing of the external and internal parts through two sealing rings (third sealing ring 61 and fourth sealing ring 63), ensuring the airtightness and cleanliness of the optical path cavity of the first light-emitting component 4.

[0053] like Figure 1-8 As shown, in some embodiments, the end of the battery compartment housing 11 away from the control compartment housing 12 is threaded with a tail sleeve 7, and a fifth sealing ring 71 is also provided between the battery compartment housing 11 and the tail sleeve 7. The end of the tail sleeve 7 away from the battery compartment housing 11 is provided with a plurality of assembly holes 72.

[0054] The tail sleeve 7 is connected to the battery compartment housing 11 by threads, and the fifth sealing ring 71 is pressed against the mating surface to form a seal. The mounting hole 72 is for threading a hanging rope to extend the functionality.

[0055] The tail sleeve 7 seals the battery compartment shell 11, facilitating the replacement of the rechargeable battery 15; the mounting hole 72 at the tail end can be used to install accessories such as lanyards and brackets, enhancing the product's portability and ease of use; the fifth sealing ring 71 ensures the waterproof performance of the battery compartment tail.

[0056] The main body shell 1, large reflector bowl 43, reflector sleeve 6, tail sleeve 7, and lamp plate holder 31 of the flashlight are all made of aluminum.

[0057] like Figure 1-8 As shown, in some embodiments, a rechargeable battery 15 is disposed inside the battery compartment housing 11, and a power-conducting spring 16 is disposed at each end of the rechargeable battery 15.

[0058] The rechargeable battery 15 is electrically connected to the switch plate 21 through the energizing spring 16 at one end, forming a complete power supply circuit. The elastic design of the energizing spring 16 can compensate for the dimensional tolerances and assembly gaps of the rechargeable battery 15, ensuring reliable conductivity under any conditions.

[0059] The rechargeable battery 15 provides a stable power supply. The energizing springs 16 at both ends ensure that the rechargeable battery 15 is in close contact and conducts electricity stably within the battery compartment shell 11, while also buffering vibrations and impacts to prevent damage to the rechargeable battery 15.

[0060] like Figure 1-8 As shown, in some embodiments, the control module 2 includes a switch board 21 and a charging board 22 disposed inside the control compartment housing 12. The switch board 21 integrates a switch button 23 and an indicator light, and the charging board 22 integrates a charging interface 24. The switch board 21 is also provided with a light shield 25 corresponding to the indicator light.

[0061] One side of the control compartment housing 12 is provided with a light guide 17 corresponding to the light shield 25 and a waterproof button 18 corresponding to the switch button 23; the other side of the control compartment housing 12 is provided with a waterproof plug 19 corresponding to the charging interface 24.

[0062] The control compartment housing 12 is also threaded with a pressure ring located at one end of the battery compartment housing 11 to limit the control module 2. The first light-emitting component 4 and the second light-emitting component 5 are electrically connected to the switch board 21. The switch button 23 is used to control the lighting of the first light-emitting component 4 and the second light-emitting component 5 and the mode switching (such as strobe warning mode). The switch board 21 and the charging board 22 are electrically connected and work together. The light shield 25 confines the light emitted by the indicator light within the path of the light guide 17, and the status light is led out of the housing through the light guide 17. The waterproof button 18 triggers the switch button 23 through the internal sealing structure. The waterproof plug 19 tightly fills the gap of the charging interface 24 through elastic deformation.

[0063] The control functions are modularized, with the switch board 21 responsible for lighting control and the charging board 22 responsible for power management, with clear division of labor; the light shield 25 and the light guide 17 work together to clearly transmit the indicator light signal to the outside and avoid internal light leakage interference; the waterproof button 18 and the waterproof plug 19 ensure the sealing protection level of the control interface area without affecting operation.

[0064] In summary, by integrating dual light-emitting components with reverse settings into a single lamp head 3, a combination of focused and floodlighting modes is achieved. Its focused function uses a unique double reflector bowl and focusing lens 44 to efficiently converge light into a bright central spot for extremely long-distance illumination. The floodlighting function uses a COB lamp panel and a conical lampshade 52 to generate a wide and uniform light field with a large angle of diffusion, meeting the needs of large-area lighting. The product uses a built-in rechargeable battery 15 and a dedicated charging interface 24, providing long battery life and convenient use. At the same time, key connection parts such as the flashlight body shell 1, headlamp, and tail cover 7 adopt a multi-seal structure to effectively prevent moisture and dust intrusion, ensuring reliable use of the product in complex environments.
