[0036] This utility model provides a light-emitting structure and a flashlight, such as Figures 1 to 5 As shown, this invention addresses the problem in existing technologies where movement of the flashlight causes the lamp board to disconnect from the main board, affecting the flashlight's usability. Specifically, the light-emitting structure 10 includes a pin header 100 that penetrates the main board 200 and the lamp board 300 to connect them. The pin header 100 electrically connects the main board 200 and the lamp board 300, allowing the main board 200 to control the operation of the lamp board 300. Simultaneously, the pin header 100 maintains the relative fixation of the lamp board 300 and the main board 200, preventing the lamp board 300 from shaking relative to the main board 200 during flashlight movement, which could cause the lamp board 300 to disconnect from the main board 200, preventing the lamp board 300 from emitting light and affecting the normal use of the flashlight. Specifically, the pin header 100 includes several connecting pins 110 and several support plates 120. The connector pins 110 pass through the main board 200 and the lamp board 300. While maintaining an electrical connection between the main board 200 and the lamp board 300, the connector pins 110 also fix the lamp board 300 onto the main board 200, maintaining their relative positions and ensuring the flashlight's normal and stable operation. The support plate 120 is used to mount the connector pins 110, providing support for them. In this application, a pin header component 100 includes a support plate 120 and two connector pins 110. Both connector pins 110 are mounted on the support plate 120. When the support plate 120 is installed inside the lamp board 300, the connector pins 110 on the support plate 120 further enable an electrical connection between the lamp board 300 and the main board 200, and also fix the lamp board 300 onto the main board 200.
[0037] To simultaneously achieve electrical connection and relative fixation between the lamp board 300 and the main board 200 via the connector pin 110, the connector pin 110 includes a vertical section 111 and an overlapping section 112. The vertical section 111 penetrates into the main board 200 and exits from the side of the main board 200 away from the lamp board 300, where it can be further connected to the main board 200 by soldering. The overlapping section 112 overlaps the side of the lamp board 300 away from the main board 200, and the overlapping section 112 is perpendicular to the vertical section 111. Furthermore, the overlapping sections 112 of the two connecting pins 110 on the support plate 120 are bent in opposite directions, so that the overlapping sections 112 can overlap at different positions on the lamp board 300, and the overlapping positions of the overlapping sections 112 on the lamp board 300 are kept symmetrical, thereby further securing the lamp board 300 on the main board 200 and preventing the lamp board 300 from falling off the main board 200.
[0038] Furthermore, the motherboard 200 is provided with several connection holes 210 for the connection pins 110 to pass through. One connection hole 210 corresponds to one connection pin 110. In order to prevent the connection pins 110 from falling out of the connection hole 210, the connection hole 210 and the connection pins 110 are interference-fitted. Only by applying a certain force can the connection pins 110 be pulled out of the connection hole 210, thus preventing the connection pins 110 from falling out of the connection hole 210 due to the movement of the flashlight. In this application, to ensure a more stable connection between the lamp board 300 and the main board 200, two pin headers 100 are provided, meaning there are a total of four connecting pins 110. Correspondingly, the main board 200 has four connecting holes 210. In other embodiments, different numbers of pin headers 100 can be provided depending on the situation. For example, when it is only necessary to control whether the lamp board 300 emits light, only one pin header 100 can be provided, corresponding to two connecting pins 110. In this case, the main board 200 has only two connecting holes 210, and the main board 200 and the lamp board 300 are connected through the two connecting pins 110. When it is necessary to control the lamp board 300 to run different light-emitting modes through the motherboard 200, such as adjusting the brightness and flashing frequency, multiple pin headers 100 are required. Multiple connecting pins 110 are then set up to connect the motherboard 200 and the lamp board 300, so that the motherboard 200 can control the lamp board 300 for different light-emitting modes. The motherboard 200 also needs to have a corresponding number of connecting holes 210 according to the number of connecting pins 110.
[0039] Meanwhile, the lamp board 300 is provided with a positioning groove 320 for the support plate 120 to be inserted. By providing the positioning groove 320, the main board 200 and the lamp board 300 can be quickly aligned. When the lamp board 300 is installed on the main board 200, the installation position of the lamp board 300 relative to the main board 200 is correct only when all the connection holes 210 are located within the positioning groove 320. Furthermore, when the support plate 120 is placed within the positioning groove 320, it also allows the lamp board 300 and the main board 200 to maintain a tighter fit, further preventing the lamp board 300 from falling off the main board 200. In addition, the positioning groove 320 is U-shaped. The side of the positioning groove 320 away from the center of the lamp board 300 is open, and the width of the side closer to the center is greater than the width of the side away from the center. The opening is provided to better align the connection hole 210. The width of the side closer to the center is greater than the width of the side away from the center to prevent the pin header 100 from detaching from the positioning groove 320. Several additional grooves 321 are provided on the side closer to the center of the lamp board 300 to provide an operating position for removing the pin header 100 from the main board 200 during subsequent flashlight maintenance. At this time, there is no other structure blocking the side of the pin header 100 near the opening of the positioning groove 320. However, due to the grooves 321 on the side closer to the center of the lamp board 300, the side of the pin header 100 is not completely in contact with the lamp board 300, and there is still a gap between the pin header 100 and the lamp board 300. Therefore, when removing the pin header 100 from the motherboard 200, tools can be used to clamp the opposite sides of the pin header 100 at the same time, so that the pin header 100 can be removed from the motherboard 200 by tools, which facilitates the maintenance of the light-emitting structure later.
[0040] When mounting the lamp board 300 onto the motherboard 200, multiple pin headers 100 are typically required to enable more lighting modes. To facilitate the simultaneous insertion and removal of multiple pin headers 100, the light-emitting structure 10 also includes a connecting plate 400. The connecting plate 400 is located within the positioning slot 320, and the support plate 120 is mounted on the connecting plate 400. The connecting plate 400 brings together the support plates 120 among the multiple pin headers 100. When the light-emitting structure 10 needs to be removed or removed, simply by removing or inserting the connecting plate 400, the entire light-emitting structure 10 can be detached from the motherboard 200. This facilitates separate maintenance of the motherboard 200 and the lamp board 300, or reinstallation on the motherboard 200 to connect and secure the lamp board 300 and the motherboard 200.
[0041] A flashlight includes a light-emitting structure 10, a housing 20, a lens 30, and a power supply 40. The housing 20 is elongated and open at one end. The housing 20 provides support for the other structures within the flashlight. The light-emitting structure 10, the main board 200, and the lamp board 300 are all housed within the housing 20, which provides support and protection for these components. The lens 30 is mounted on the housing 20, specifically at the open end. When the lens 30 is installed, LED beads 310 on the lamp board 300 extend into the lens 30, further diffusing the light emitted by the LED beads 310 through the lens 30, thereby improving the flashlight's illumination effect. The power supply 40 is installed inside the housing 20, specifically on the side of the main board 200 away from the lens 30. The power supply 40 is electrically connected to the main board 200, thereby supplying power to the LED 310 through the main board 200 to ensure continuous operation of the flashlight. Additionally, a bracket 50 is provided between the power supply 40 and the main board 200 to separate them, preventing direct contact and thus avoiding interference from the power supply 40 when the main board 200 generates heat during operation. Furthermore, the lamp board 300 is also mounted on the bracket 50, specifically fixed to it with bolts, providing support for the lamp board 300.
[0042] Flashlights typically employ a battery replacement design or a rechargeable mechanism. Replacing batteries requires frequent disassembly of the flashlight, which is detrimental to its structural stability. Therefore, the flashlight in this application uses a rechargeable design. To enable charging, a charging port 70 is provided on the housing 20, and a connector 220 is provided on the mainboard 200. The charging port 70 corresponds to the connector 220. Therefore, when charging the flashlight, an external charging device is connected to the connector 220 on the mainboard 200 through the charging port 70. After connection, the flashlight can be charged. After charging is complete, the charging device can be separated from the flashlight. To prevent water or other substances from entering the flashlight through the charging port 70 when not in use and causing damage, a cover 80 is provided inside the charging port 70. The cover 80 blocks the charging port 70. Only when the charging port 70 is needed is the cover 80 adjusted to expose the charging port 70, allowing the flashlight to connect to the charging device.
[0043] In addition, a switch port 60 is provided on the side of the housing 20 opposite to the charging port 70. A button assembly 61 is installed on the main board 200, and the button assembly 61 is connected to the switch port 60, thereby controlling the operation of the flashlight through the button assembly 61. An indicator light 91 and a light-blocking assembly 90 are also provided. The light-blocking assembly 90 blocks the light emitted by the LED beads 310 on the light panel 300, preventing the light emitted by the LED beads 310 from interfering with the indicator light 91 and making the indicator light 91 invisible. The light emitted by the indicator light 91 can penetrate the button assembly 61 and be emitted from the switch port 60, allowing the user to judge the operating status of the flashlight through the indicator light 91. For example, the user can judge whether the flashlight has sufficient power and whether the flashlight has finished charging by looking at the indicator light 91.
[0044] Therefore, when using the pin header 100 in this application to connect the light panel 300 and the main board 200 in a flashlight, first insert the connecting pin header 110 into the support plate 120 to form the pin header 100. Then, select an appropriate number of pin headers 100 as needed and connect them through the connecting plate 400. Then, insert the connected pin headers 100 into the positioning groove 320 so that the support plate 120 and the connecting plate 400 are installed in the positioning groove 320. At this time, the vertical section 111 of the connecting pin header 110 is inserted into the connecting hole 210, and the overlapping section 112 overlaps on the side of the light panel 300 away from the main board 200, thus completing the connection and fixation between the light panel 300 and the main board 200.
