A kind of embedded road stud and its manufacturing method

Abstract

An embedded road stud and its manufacturing method. The embedded road stud includes a control module and a light-emitting module, the control module is connected to the light-emitting module circuit, and also includes a bottom case and a transparent cover plate. The bottom case is composed of a side plate and a bottom plate. Cup-shaped structure, the transparent cover is installed on the upper end of the bottom shell, the transparent cover and the bottom shell form a built-in chamber, the lower surface of the transparent cover is provided with a baffle extending vertically downward, the baffle is a ring structure, and is connected with the The inner surface of the side plate of the bottom case is bonded and clamped; the control module and the light emitting module are placed in the built-in chamber, and the built-in chamber is filled with potting glue. Because the baffle of the transparent cover and the side plate of the bottom shell are fitted and snapped together, and the interior of the built-in chamber is filled with potting glue, each functional module inside the embedded road stud is a solid structure without gaps and air bubbles, increasing the Waterproof performance and compressive performance of embedded road studs.

Description

technical field [0001] The application relates to the field of road traffic safety facilities, in particular to an embedded road stud and a manufacturing method thereof. Background technique [0002] Embedded road stud is a type of road stud. In road traffic safety facilities or products, embedded road stud can clearly outline the outline and edge of the road in rainy, foggy weather and road curves, and induce The driver's line of sight can eliminate road safety hazards. Existing embedded road studs such as figure 1 As shown, it is generally composed of a cast aluminum shell a, a transparent cover plate b, a spike light c, a circuit board d and a waterproof rubber ring e, and the waterproof rubber ring e is installed between the transparent cover plate b and the cast aluminum shell a The joint is used to prevent water or other liquids from entering the spike. [0003] Its production process is to put the circuit board d and the road stud lamp c into the cast aluminum shel...

AI Technical Summary

Problems solved by technology

[0004] 1) There are gaps between the transparent cover plate b and the road stud lamp c, between the road stud lamp c and the circuit board d, and between the circuit board d and the cast aluminum shell a. The application conditions of the embedded road stud are harsh and require Withstanding wind and rain, vehicle rolling, etc., the waterproof rubber ring is not enough to resist all the infiltrating liquids, and the existence of these gaps will increase the problem of water seepage, causing short circuits, and greatly shortening its service life;

[0005] 2) The gaps in the above-mentioned road studs will also cause compression problems. When a car rolls over or impacts the embedded road studs, the gaps in the road studs are reduced, causing the internal parts to squeeze each other, and the parts cannot withstand easily damaged after pressure
