Detailed Implementation
[0021] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0022] like Figures 1 to 4The diagram shows a signal light housing according to this application, comprising a base shell 11 and a cover 12. Both the base shell 11 and the cover 12 are cast from aluminum alloy, resulting in light weight, high structural strength, and good heat dissipation. The front of the base shell 11 has a mounting portion 111 for mounting a light-emitting unit. The mounting portion 111 has a mounting recess 112 for mounting a control board. A limiting groove 113 is formed in the mounting recess 112, which can be adapted to the side of the control board, thereby limiting the mounting position of the control board. A light-emitting hole 114 is formed on the periphery of the mounting portion 111 of the base shell 11 for allowing light emitted by the light-emitting unit to pass through. The cover 12 has a mask hole 121 for projecting light from the light-emitting unit. A mask is installed within the mask hole 121 to seal the base shell 11 and scatter light. The base shell 11 has a groove 115 formed on the outer periphery of the light emission hole 114, and the door cover 12 has a press-fit flange 122 formed on the outer periphery of the mask hole 121 for press-fitting into the groove 115. The door cover 12 and the base shell 11 are provided with hinges 13 for hinged connection between the two, and lock holes 14 for fixed connection between the two. Thus, during installation, the mask is installed on the door cover 12, and then the door cover 12 is directly rotated to the front of the base shell 11 via the hinges 13, and the press-fit flange 122 is pressed into the groove 115 to achieve a sealing and limiting connection between the two. In the design, the base shell 11 is designed as a square with rounded chamfers. The square base shell 11 is easy to assemble and has a stable structure, and the rounded chamfers help to reduce wind resistance. The door cover 12 is round to fit the light emission hole 114, which simplifies the structure of both and reduces the amount of structural materials used.
[0023] The signal light housing in this solution is designed to form an integrated installation unit by combining the bottom shell 11 and the door cover 12, which makes the installation of the light-emitting unit and control board simpler and more convenient. The structural design reduces the overall volume of the housing, making the overall structure lighter, using less material, and lowering the production cost.
[0024] In one specific implementation, the side of the base shell 11 is provided with a connecting recess 116 and a connecting protrusion 117. The connecting recess 116 and the connecting protrusion 117 allow adjacent base shells 11 to be connected, facilitating the installation of multiple signal lights in a group. This enables quick and precise installation, improving the overall structural integrity of the signal lights and making the structure more stable. A connecting portion 118 is provided on the side of the base shell 11, with a connecting hole 1181. During installation, after adjacent signal lights are connected using the connecting recess 116 and the connecting protrusion 117, the two adjacent base shells 11 are fixedly connected by screws threaded through the connecting hole 1181. The installation structure is simple.
[0025] In one specific implementation, the hinge 13 is disposed on the front of the bottom shell 11 and protrudes from the front of the bottom shell 11, thereby placing the door cover 12 on one side of the bottom shell 11 to reduce the volume of the door cover 12 and further reduce the weight of the outer shell.
[0026] In one specific implementation, the front of the door cover 12 has a brim mounting hole 123 on the outer periphery of the press-fit flange 122 for detachable installation of the brim of the signal light, and the back of the door cover 12 has a mask mounting hole 124 on the inner periphery of the press-fit flange 122 for detachable installation of the mask of the signal light. The installation structure is simple and easy to install and remove.
[0027] In one specific implementation, the reverse side of the bottom shell 11 is provided with decorative panel mounting holes 119 for mounting decorative panels.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
