Abstract
Description
Technical Field
[0001] The present invention relates to a lamp, more specifically a signal lamp for a vehicle. Background Art
[0002] Signal lights are used for signaling on vehicles and are an essential component. They are often mounted in prominent locations on vehicles. If a signal light is not waterproof, moisture or rainwater can enter the light, accelerating aging, damaging, or even causing a short circuit in the light's driver circuit. Therefore, waterproof performance is crucial. Existing signal lights suffer from suboptimal waterproof structural designs, resulting in insufficient waterproof performance. Summary of the Invention
[0003] The purpose of the invention is to overcome the defects of the prior art and provide a waterproof signal light with reasonable structural design and good waterproof performance.
[0004] To achieve the above object, the present invention provides the following technical solutions:
[0005] A waterproof signal lamp, comprising a lampshade and a lamp holder, wherein the lampshade is covered on the lamp holder to form an assembly cavity, the lamp holder is provided with a light-emitting component, the light-emitting component is placed in the assembly cavity, the lampshade comprises a top and a side panel surrounding the top, and is characterized in that: the lampshade is provided with a waterproof device located on the inner side of the side panel, the waterproof device comprises an annular waterproof inner retaining wall and a waterproof outer retaining wall surrounding the outer periphery of the waterproof inner retaining wall, an annular waterproof groove is formed between the waterproof inner retaining wall and the waterproof outer retaining wall, a rubber gasket is padded in the waterproof groove, the lamp holder comprises a bottom plate covering the mouth surrounded by the side panels, an annular wall panel is raised on the bottom plate, the wall panel is inserted into the side panel, thereby forming a waterproof gap between the wall panel and the side panel, the top of the wall panel is inserted into the waterproof groove and pressed against the rubber gasket.
[0006] By adopting the above technical solution, an annular waterproof structure is formed on the inner side of the side panel of the lampshade, and the wall panel and the side panel cooperate to form a waterproof gap. At the same time, the top of the wall panel is inserted into the waterproof groove and pressed against the rubber gasket. At the end of the waterproof gap, a good waterproof sealing effect is achieved through the waterproof inner retaining wall, the waterproof groove and the rubber gasket.
[0007] Preferably, the waterproof outer retaining wall is formed by the wall of the lampshade. The wall corresponding to the waterproof outer retaining wall within the waterproof groove protrudes beyond the inner wall of the side panel, thereby forming a transition step where the waterproof outer retaining wall and the inner wall of the side panel meet. The outer peripheral surface of the top of the wall panel is provided with an annular step groove. The transition step forms an inner gap within the step groove, which connects with the waterproof gap to form a labyrinthine gap. With this structural design, a labyrinthine gap is formed between the lampshade and the base before the waterproof groove, providing waterproof performance.
[0008] Preferably, the top of the lampshade is in a three-stepped configuration, comprising a bottom step, an intermediate step, and a top step. The waterproof groove corresponds to the inner side of the intermediate step, forming the inner and outer waterproof retaining walls within the intermediate step. With this structural design, the three-stepped top of the lampshade not only achieves a protruding design for the lampshade and a better protruding mounting position for the signal light, but also facilitates the processing and formation of the internal waterproof structure by forming the intermediate step.
[0009] The present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See attached Figures 1 to 5 The present invention discloses a waterproof signal lamp, comprising a lampshade 1 and a lamp holder 2. The lampshade 1 is covered on the lamp holder 2 to form an assembly cavity. The lamp holder 2 is provided with a light-emitting component 3. The light-emitting component 3 includes a lamp board, a lamp bead and a lamp cup. The light-emitting component is placed in the assembly cavity. The lampshade 1 includes a top 11 and a side panel 12 surrounding the top 11. The lampshade 1 is provided with a waterproof device located inside the side panel 12. The waterproof device includes an annular waterproof inner retaining wall 13 and a waterproof outer retaining wall surrounding the outer periphery of the waterproof inner retaining wall 13. An annular waterproof groove 15 is formed between the retaining wall 14, the waterproof inner retaining wall 13, and the waterproof outer retaining wall 14. A rubber gasket 16 is padded in the waterproof groove 15. The lamp holder 2 includes a bottom plate 21 covering the opening formed by the side panels 12 of the lampshade 1. An annular wall panel 22 protrudes from the bottom plate 21. The wall panel 22 is inserted into the side panels 12, thereby forming a waterproof gap I between the wall panel 22 and the side panels 12. The top of the wall panel 22 is inserted into the waterproof groove 15 and presses against the rubber gasket 16. An annular waterproof structure is formed on the inner side of the side panels 12 of the lampshade. The wall panel and the side panels cooperate to form a waterproof gap. External impurities need to first pass through the waterproof gap to reach the waterproof groove. At the same time, the top of the wall panel is inserted into the waterproof groove and presses against the rubber gasket. The waterproof inner retaining wall, waterproof groove, and rubber gasket achieve a good waterproof sealing effect.
[0016] In this specific embodiment, the waterproof outer retaining wall 14 is formed by the wall of the lampshade 1, eliminating the need for a separate protrusion within the lampshade to form a waterproof outer retaining wall, resulting in a more compact structure. Furthermore, the waterproof outer retaining wall 14 corresponds to a wall 141 within the waterproof groove 15 that protrudes beyond the inner wall 121 of the side panel 12, thereby forming a transition step 16 at the junction of the waterproof outer retaining wall 14 and the inner wall 121 of the side panel 12. The outer circumferential surface of the top of the wall panel 22 is provided with an annular step groove 221. The transition step 16 corresponds to forming an inner gap II within the step groove 221. The inner gap II is connected to the waterproof gap I to form a labyrinth gap. The inner end of the waterproof gap is connected to the inner gap formed by the transition step within the step groove, thereby forming a labyrinth gap before the waterproof groove, improving waterproof performance.
[0017] As a signal indicator, the signal light needs to be prominently displayed. The top 11 of the lampshade 1 is in a three-stepped shape, comprising a bottom step 111, an intermediate step 112, and a top step 113. The waterproof groove 15 corresponds to the inner side of the intermediate step 112, forming the waterproof inner retaining wall 13 and the waterproof outer retaining wall 14 within the intermediate step 112. This multi-stepped shape of the lampshade facilitates protrusion, and the intermediate step provides the wall thickness for the waterproof groove. This processing forms the waterproof groove, naturally forming the waterproof inner retaining wall and the waterproof outer retaining wall, resulting in a reliable and compact structure.
