[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] See also Figures 1 to 6As shown, this utility model provides a tail cover, which includes: a housing 10 having a first mounting cavity 11 and a second mounting cavity 12 that are independent of each other, and a first circuit board 20 disposed in the first mounting cavity 11; a control mechanism including a moving component 80 and a control component 90 installed in the housing 10, the moving component 80 being movable relative to the housing 10 and being able to cooperate with the control component 90 during the movement to enable the control component to issue at least two control signals; and a charging module 40 including a conductive connection part 42 and a charging unit 41 installed in the second mounting cavity 12, the first end of the conductive connection part 42 being conductively connected to the charging unit 41, the second end of the conductive connection part 42 being conductively connected to the first circuit board 20, and the charging unit 41 including a charging interface 413.

[0027] In this embodiment, the first circuit board 20 is configured to be electrically connected to the battery. The movable component 80 is movable relative to the housing 10 and can cooperate with the control component 90 during movement to enable the control component to issue at least two control signals to achieve second-order or multi-order control.

[0028] The tail cover of this application has a charging module 40, which includes a conductive connection part 42 and a charging unit 41 installed in the second mounting cavity 12. The first end of the conductive connection part 42 is conductively connected to the charging unit 41, and the second end of the conductive connection part 42 is conductively connected to the first circuit board 20. The charging unit 41 includes a charging interface 413, which is configured to be electrically connected to an external charger. The charging current is transmitted from the external charger to the first circuit board 20 through the conductive connection part 42, and then from the first circuit board 20 to the battery, thereby realizing the charging of the battery.

[0029] With the above settings, users no longer need to disassemble the flashlight to replace or charge the internal battery, reducing operational steps and improving convenience and efficiency. Especially for those who use the flashlight outdoors or need it in emergency situations, it can be charged instantly without carrying additional batteries or charging equipment, achieving fast charging of the flashlight and thus improving the adaptability of the tail cap.

[0030] It should be noted that traditional flashlights have limited button functionality, primarily used for basic operations such as turning the flashlight on and off and simple brightness adjustment. These buttons are usually separate components independent of the charging system, occupying space in the flashlight's casing and hindering the overall miniaturization and simplification of the flashlight's design. User demands are driving integrated design, with users increasingly requiring convenience. In outdoor or emergency situations, users expect flashlights to charge quickly and be easy to operate. This application integrates the charging module 40 with the tail cap, reducing operational steps and providing both charging and button functionality, allowing users to quickly access the flashlight in emergencies. From a cost perspective, the integrated design reduces the number of parts, thereby lowering raw material costs, assembly costs, and after-sales maintenance costs. It better meets various multi-functional needs, makes operation more intuitive, improves the user experience, and ultimately makes this design more commercially viable.

[0031] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the moving component 80 is capable of moving along a first direction toward or away from the first circuit board 20. The moving component 80 has at least two trigger positions. A light guide structure is provided at one end of the moving component 80 facing the first circuit board 20. The control component 90 is mounted on the first circuit board 20. The control component 90 includes a beam emitting unit 91 and a beam receiving unit. The beam receiving unit includes at least two beam receiving parts 92. The beam receiving parts 92 are configured to emit control signals. The control signals emitted by the at least two beam receiving parts 92 are different. The at least two trigger positions correspond one-to-one with the at least two control signals. When the moving component 80 moves to different trigger positions, the light guide structure can guide the beam emitted by the beam emitting unit 91 to the corresponding beam receiving part 92, so that the beam receiving part 92 emits the corresponding control signal.

[0032] In this embodiment, the first direction refers to the vertical direction, that is, the moving direction of the moving component 80. The moving component 80 has at least two trigger positions, each trigger position corresponding to a control signal, and the control signals corresponding to different trigger positions are different. The beam emitting unit 91 can emit a beam, and each beam receiving unit 92 can emit a control signal, enabling second-order control or multi-order control. For ease of understanding, the working process of realizing second-order control is explained using the moving component 80 having two trigger positions as an example. For ease of distinction, the two trigger positions are named the first trigger position and the second trigger position, respectively, and the two control signals are named the first control signal and the second control signal, respectively. The first control signal and the second control signal are emitted by two beam receiving units 92, respectively. For ease of distinction, the beam receiving unit 92 that emits the first control signal is now named the first beam receiving unit, and the beam receiving unit 92 that emits the second control signal is named the second beam receiving unit. The first trigger position corresponds to the first control signal; that is, when the moving component 80 moves to the first trigger position, the control component 90 issues the first control signal. The second trigger position corresponds to the second control signal; that is, when the moving component 80 moves to the second trigger position, the control component 90 issues the second control signal. When the moving component 80 moves along the first direction to the first trigger position, the light guide structure can change the movement path of the light beam emitted by the light beam emitting unit 91, guiding the light beam emitted by the light beam emitting unit 91 to the first light beam receiving unit. After receiving the light beam, the first light beam receiving unit generates the first control signal. When the moving component 80 continues to move along the first direction until it reaches the second trigger position, the light beam emitted by the light beam emitting unit 91 is guided to the second light beam receiving unit via the light guide structure. After receiving the light beam, the second light beam receiving unit generates the second control signal. Users can, but are not limited to, move the moving component 80 along the first direction to different trigger positions by lightly pressing or deeply pressing, thereby triggering different functions. As can be seen from the above, by changing the optical path of the light beam through the light guide structure, the light beam is guided to the corresponding light beam receiving part 92, thereby realizing the emission of different control signals. Compared with the existing technology that relies on the closing and opening of physical contact points to realize the conduction and disconnection of the circuit, the wear of contact points can be avoided, thereby significantly improving the functional stability of the switch.

[0033] It should be noted that the above is only one way to implement second-order or multi-order control in the control mechanism. The control mechanism can also adopt existing technologies (for example, the structure of second-order or multi-order control in Hall switches). The specific structure will not be described here.

[0034] In one embodiment of this utility model, an indicator light is provided on the first circuit board 20. When the indicator light is on, it indicates that the flashlight is in a charging state, and when the indicator light is off, it indicates that the flashlight is not charging. The indicator light is a colored light. The moving component 80 is made of a light-transmitting material (e.g., plastic). Whether the indicator light is on can be seen through the moving component 80, so as to determine whether the flashlight is in a charging state, thereby realizing the charging and display functions.

[0035] In one embodiment, the charging interface 413 is a USB interface. With continuous improvements in electronic manufacturing processes, it has become possible to integrate the functions of a USB interface and a button into a single component. Miniaturized and highly integrated circuit design and manufacturing technologies enable this innovative design to be realized without significantly increasing costs, allowing for the arrangement of USB interface-related circuitry and integrated button functions within the limited space of a flashlight. The integration of the USB interface and button better meets the needs of various multi-functional applications, making operation more intuitive and improving the user experience.

[0036] In one embodiment, the beam emitting unit 91 is an infrared emitting diode, and the beam receiving unit 92 is an infrared receiving diode.

[0037] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the light guide structure includes at least two light guide parts, which are sequentially arranged on the moving component 80 along the first direction. When the moving component 80 moves to different trigger positions, the light guide part at the corresponding height can guide the light beam emitted by the light beam emitting unit 91 to the corresponding light beam receiving part 92.

[0038] In this embodiment, by sequentially arranging at least two light guides along a first direction on the movable component 80, and each light guide being able to guide the beam emitted by the beam emitting unit 91 to the corresponding beam receiving unit 92, multi-level control of the switch is achieved. When the user moves the movable component 80 to different trigger positions, the control component 90 can generate different control signals to execute different functions. For example, one trigger position can be used to turn on the device, while another trigger position can be used to adjust the brightness or switch modes. In addition, the beam guiding and receiving are non-contact, that is, the signal transmission has no physical contact delay, and the response speed can reach the nanosecond level, which significantly improves the operating sensitivity and response speed of the switch. Furthermore, this non-contact design avoids mechanical wear, and even after long-term or frequent operation, the optical path between the light guide and the beam receiving unit 92 can still remain stable, improving the durability and reliability of the switch.

[0039] In one embodiment, the light guide is a reflector or a reflective prism.

[0040] See also Figures 1 to 6As shown, in one embodiment of the present invention, the charging unit 41 includes a second circuit board 411, which is installed in the second mounting cavity 12. The second circuit board 411 is provided with a positive electrode connection area and a negative electrode connection area. The conductive connection part 42 includes at least two first conductive connectors 421. The first end of a portion of the at least two first conductive connectors 421 is conductively connected to the positive electrode connection area, the first end of another portion of the at least two first conductive connectors 421 is conductively connected to the negative electrode connection area, and the second end of the first conductive connector 421 is conductively connected to the first circuit board 20.

[0041] In this embodiment, by providing a positive connection area and a negative connection area on the second circuit board 411, the correct inflow and outflow of charging current can be ensured, avoiding charging failure or device damage caused by incorrect polarity. The use of at least two first conductive connectors 421 provides multiple connection points, ensuring a stable and reliable electrical connection between the charging unit 41 and the first circuit board 20 even under device vibration or changes in the operating environment.

[0042] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the charging unit 41 further includes at least two second conductive connectors 412 mounted on the second circuit board 411. A portion of the at least two second conductive connectors 412 is conductively connected to the positive electrode connection area, and another portion of the at least two second conductive connectors 412 is conductively connected to the negative electrode connection area. At least two first conductive connectors 421 are correspondingly arranged with at least two second conductive connectors 412, and the first end of the first conductive connector 421 is conductively connected to the corresponding second conductive connector 412.

[0043] In this embodiment, by providing the second conductive connector 412, a conductive connection between the first conductive connector 421 and the second circuit board 411 can be achieved.

[0044] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the outer peripheral surface of the second conductive connector 412 is clearance-fitted with the side wall of the second mounting cavity 12. The tail cover also includes an insulating member 60, which is installed in the second mounting cavity 12. The insulating member 60 is provided with a mounting groove 61, and the second conductive connector 412 is installed in the mounting groove 61.

[0045] In this embodiment, by embedding the second conductive connector 412 into the mounting groove 61 on the insulating member 60, electrical isolation between the charging unit 41 and the housing 10 can be greatly achieved, avoiding the risk of accidental electric shock and short circuit.

[0046] In one embodiment, the insulating element 60 is made of an insulating material (e.g., rubber or plastic).

[0047] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the housing 10 further has a spacer 30 separating the first mounting cavity 11 and the second mounting cavity 12. The spacer 30 is provided with a first through hole 31 connecting the first mounting cavity 11 and the second mounting cavity 12. The tail cap further includes a waterproof structure 50, which is used to seal the gap between the outer wall surface of the conductive connection part 42 and the inner wall surface of the first through hole 31. The second end of the conductive connection part 42 passes through the first through hole 31 and is electrically connected to the first circuit board 20.

[0048] In this embodiment, the waterproof structure 50 is used to seal the gap between the outer wall of the conductive connection part 42 and the inner wall of the first through hole 31, ensuring that even in severe weather conditions, such as heavy rain or snow, moisture can be effectively prevented from seeping into the first mounting cavity 11 of the housing 10 through the tiny gap between the conductive connection part 42 and the first through hole 31, avoiding short circuits and equipment damage to the first circuit board 20, and greatly improving the reliability and service life of the flashlight.

[0049] See also Figures 1 to 6 As shown, in one embodiment of the present invention, there are at least two first through holes 31, which are spaced apart. The at least two first through holes 31 are correspondingly arranged with at least two first conductive connectors 421. The second end of the first conductive connector 421 passes through the corresponding first through hole 31 and is conductively connected to the first circuit board 20. The outer wall surface of the first conductive connector 421 is clearance-fitted with the inner wall of the corresponding first through hole 31.

[0050] In this embodiment, at least two first through holes 31 are correspondingly arranged with at least two first conductive connectors 421. The charging current can be transmitted to the first circuit board 20 through multiple independent paths, which can effectively disperse the current and reduce the current load of a single first conductive connector 421, thereby improving charging efficiency. The waterproof structure 50 is used to ensure that the gap between the outer wall surface of the first conductive connector 421 and the inner wall surface of the first through hole 31 is completely sealed, preventing moisture from the external environment from seeping into the first mounting cavity 11 through the gap between the first through hole 31 and the first conductive connector 421, effectively preventing short circuits and equipment damage to the first circuit board 20.

[0051] See also Figures 1 to 6As shown, in one embodiment of the present invention, the waterproof structure 50 includes at least two waterproof sealing rings 51. The waterproof sealing rings 51 are located on the side of the first circuit board 20 near the second circuit board 411. The at least two waterproof sealing rings 51 are correspondingly arranged with at least two first conductive connectors 421. The waterproof sealing rings 51 are sleeved on the corresponding first conductive connectors 421 to seal the gap between the outer wall surface of the first conductive connector 421 and the inner wall surface of the first through hole 31.

[0052] In this embodiment, by providing a waterproof sealing ring 51 on the side of the first circuit board 20 near the second circuit board 411, the gap between the first conductive connector 421 and the first through hole 31 can be sealed, ensuring that even under severe weather conditions, such as heavy rain or snow, moisture cannot seep into the first receiving cavity through the gap between the first through hole 31 and the first conductive connector 421, reducing the risk of short circuit in the first circuit board 20 and ensuring the safety of the charging process.

[0053] In one embodiment, the waterproof sealing ring 51 is made of rubber.

[0054] In one embodiment, the first conductive connector 421 is a screw or bolt, and the second conductive connector 412 is a nut.

[0055] See also Figures 1 to 6 As shown, in one embodiment of the present invention, the second mounting cavity 12 is disposed on the side wall of the housing 10, and the side wall of the housing 10 is provided with a first opening 13 communicating with the second mounting cavity 12. The second mounting cavity 12 communicates with the outside of the housing 10 through the first opening 13, and the charging interface 413 is disposed at the location of the first opening 13.

[0056] In this embodiment, a first opening 13 communicating with the second mounting cavity 12 is provided on the side wall of the housing 10. The charging interface 413 communicates with the outside through the first opening 13. When charging is required, an external charger can be directly connected to the charging interface 413 for charging. At the same time, the first opening 13 also helps to improve the heat dissipation of the charging unit 41, accelerating the dissipation of heat from the second circuit board 411 and the charging interface 413 to the environment, preventing performance degradation or safety issues caused by overheating.

[0057] See also Figures 1 to 6As shown, in one embodiment of the present invention, the tail cover further includes a rotating structure 70, which is sleeved on the housing 10 and can rotate relative to the housing 10. The rotating structure 70 is located on the outer periphery of the charging module 40, and the second mounting cavity 12 is located on the rotation path of the rotating structure 70. The rotating structure 70 can cover the first opening 13. The rotating structure 70 is provided with a second opening 71. When the rotating structure 70 rotates to the point where the second opening 71 corresponds to the first opening 13, the charging interface 413 is located in the second opening 71.

[0058] In this embodiment, when the rotating structure 70 rotates until the second opening 71 corresponds to the first opening 13, the charging interface 413 is located within the second opening 71. That is, the rotating structure 70 does not obstruct the charging interface 413, and the external charger can connect to the charging interface 413 sequentially through the second opening 71 and the first opening 13. The rotating structure 70 can rotate relative to the housing 10 and cover the first opening 13, providing a layer of physical protection for the charging interface 413 and effectively preventing dust, moisture, etc., from entering the first mounting cavity 11. Simultaneously, by rotating the rotating structure 70 to control the exposure or concealment of the charging interface 413, misoperation during non-charging states is avoided, improving the overall reliability and safety of the device.

[0059] It should be noted that this application utilizes the limited space of the tail cover to arrange the charging module 40 and the rotating structure 70 on the housing 10, allowing the rotating structure 70 to conceal the charging interface 413 during rotation while also providing waterproofing and dustproofing. The tail cover of this application integrates the second-order or even multi-order moving components 80 and control components 90 with the charging module 40 into a single unit. Compared to traditional designs that separate the charging method from the switch, which occupies a certain amount of space, this design is beneficial for overall miniaturization and simplification.
