[0026] The present invention provides a mining lamp mounting structure as follows: Figures 1-7 As shown, it includes a lamp housing 1, a light cup 2 disposed within the lamp housing 1, a main control board 3 located behind the light cup 2, a front cover 4 located at the front end of the lamp housing 1, button structures 5, a speaker cover 6, and a camera 7 disposed on both sides of the lamp housing 1. Unlike existing technologies, this button structure 5 includes a button mounting window on one side of the lamp housing 1, a button circuit board 18 disposed within the mounting window, and an integrated button cover 19 covering the mounting window. The button cover 19 has several function button sleeves 20, which are integrally formed with the button cover 19 through secondary injection molding. One end of each function button sleeve 20 is connected to a corresponding button contact 21 on the button circuit board 18, and the button circuit board 18 is electrically connected to the main control board 3. The inner edge of the button mounting window has a recessed step 23. A corresponding first sealing ring 22 is provided between the button mounting window and the button cover 19. The button cover 19 and the first sealing ring 22 are connected and fixed to the step 23 of the button mounting window from the outside to the inside by several bolts 15c. The outer edge of the button circuit board 18 is slightly smaller than the step 23 of the button mounting window and is connected and fixed to the button cover 19 from the inside to the outside by several bolts 15d. Because an independent button circuit board 18 is used, parallel to the button cover 19, and the function button sleeve 20 corresponds one-to-one with the button contact 21, the buttons are less likely to loosen or shift. Furthermore, if a button malfunctions and needs to be replaced, there is no need to disassemble the main control board 3; simply remove the button cover 19, making maintenance more convenient. The design of the first sealing ring 22 enhances its sealing and waterproofing effect.

[0027] The front cover has a transparent window 13 for the lamp head, and a resin lens 24a with a light transmittance of more than 95% is provided inside the window 13. There is a second sealing ring 12 with a corresponding shape between the front cover 4 and the lamp housing 1. The front cover 4 and the second sealing ring 12 are connected and fixed to the lamp housing 1 by several bolts 15a passing through the front cover 4 and the second sealing ring 12 from front to back.

[0028] Please combine Figures 8-12As shown, the lamp shell 1 extends upward and forms a space inside it above the light cup 2 for installing the camera 7. The front end cover 4 matches the lamp shell 1 and is provided with a corresponding camera transparent window 8 at the upper part, and the front end inside the camera transparent window 8 also adopts a resin lens 24b of the same material, which can reduce the overall weight of the lamp head and facilitate wearing. A support seat 9 and a camera 7 are arranged in the space. The support seat 9 is fixed at one end on the main control board 3 and is fixed at the other end with the rear end of the camera 7 and extends the front end of the camera 7 into the inside of the camera transparent window 8 (not in contact with the resin lens 23b), so that the camera 7 is fixed in the lamp shell 1 and is arranged in parallel above the light cup 2. Since the camera 7 is fixedly installed in the lamp shell 1, the camera 7 can be effectively protected and is not easy to be damaged.

[0029] The specific installation mode of the camera 7 can be as shown in Figures 3-5 As shown, the support seat 9 can be designed as a hollow rectangular structure, the rear end of which is connected to the upper end of the main control board 3 through a bolt 15e, and the front end of the support seat 9 has a camera limiting socket 10, and the rear end of the camera 7 is arranged in the limiting socket 10 to limit the camera 7 in the upward, downward, left and right directions. And the front end of the camera 7 is also connected with a downward extending support plate 26, which mainly supports the wire and prevents the wire from being broken. And the front end of the support plate 26 is also provided with a pressing plate 25, which is connected with the support seat 9 through a bolt 15f and presses the support plate 26 tightly on the front end surface of the support seat 9. At the same time, the rear end of the camera transparent window 8 also has a limiting groove 10' (see Figure 12 ) matched with the front end of the camera 7, so as to limit the camera 7 in the front and rear directions. The main control board 3 is also provided with an FPC flexible wire 11 arranged along the bottom of the support seat 9 and connected with the camera 7 to realize data transmission of the camera.
