AI Technical Summary
Technical Problem
Existing ceramic sealing structures require multiple high-temperature sintering metallization processes on the ceramic surface, which is cumbersome and costly.
Method used
The first and second sealing components are directly welded to the ceramic body, simplifying the process and reducing production costs. The stationary terminals and other components are connected by non-high-temperature welding, which improves sealing performance and reliability.
Benefits of technology
The process was simplified, production costs were reduced, the sealing and reliability of the relays were improved, the yield strength of components was prevented from decreasing at high temperatures, and the safety of the relays was enhanced.

Abstract
The application provides a ceramic sealing structure of a relay, a relay and a vehicle. The ceramic sealing structure comprises a ceramic body, a first sealing member and a second sealing member. The ceramic body comprises a first side wall, a second side wall and a third side wall. The first side wall is arranged opposite to the second side wall, and the third side wall is connected between the first side wall and the second side wall. The first side wall, the second side wall and the third side wall enclose a containing space for containing internal components of the relay. The first side wall is provided with a mounting hole, and the mounting hole is in communication with the containing space. The second side wall is provided with an assembly opening, and the assembly opening is in communication with the containing space. The first sealing member is connected with a surface of the first side wall away from the containing space, and surrounds the mounting hole. The second sealing member is connected with a surface of the second side wall away from the containing space, and surrounds the assembly opening.
