[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0023] The utility model discloses a combined automobile relay mainly used in automobile relay scenarios.

[0024] Reference Figures 1 to 4 A combined automotive relay comprises: a skeleton 1, a static spring fixing plate 2 is clamped on one side of the skeleton 1, a yoke 3 is clamped on the top of the skeleton 1, an armature 4 is fixedly connected to the top of the yoke 3, a mounting frame 14 is fixedly connected to one side of the yoke 3, an iron core 5 is fixedly connected between the bottom of the mounting frame 14 and the top of the skeleton 1, a coil 6 is arranged on the outside of the iron core 5, a main static spring 7 and a secondary static spring 8 are respectively clamped on one side of the static spring fixing plate 2, two static contacts 9 are fixedly connected to the top of the secondary static spring 8 at equal distances, a dynamic spring 11 is equidistantly clamped on the top of the armature 4, two dynamic contacts 10 are arranged between the dynamic spring 11 and the main static spring 7, and lead pins 12 are fixedly connected to the bottom of the static spring fixing plate 2, the main static spring 7, the secondary static spring 8 and the dynamic spring 11.

[0025] In the above technical solution, taking into account the increasing requirements for comfort in contemporary automobile development and the maximization of interior space, higher requirements are placed on the integration and volume of various electrical appliances and controllers within a limited space. In order to solve such problems, the specific operations are as follows: when a certain voltage or current is applied to both ends of the relay coil 6, the magnetic flux generated by the coil 6 passes through the magnetic circuit composed of the iron core 5, the yoke 3, the armature 4, and the magnetic circuit working air gap. Under the action of the magnetic field, the armature 4 is attracted to the top surface of the iron core 5, thereby pushing the normally closed contact to disconnect and the normally open contact to close; when the voltage or current at both ends of the coil 6 is less than a certain value, the mechanical reaction force is greater than the electromagnetic attraction, the armature 4 returns to the initial state, the normally open contact is disconnected, and the normally closed contact is connected. According to the requirements of system development, this design solution can be extended and developed to integrate 2-10 relays into a whole to obtain higher integration, facilitate installation and save installation space.

[0026] Reference Figures 1 to 4 In a preferred embodiment, a shell 13 is provided on the outside of the skeleton 1, and exhaust holes are provided between the cavities of the shell 13. An exhaust device 15 is provided on the top of the shell 13. The exhaust device 15 is cylindrical. The shell 13 is extended to integrate multiple relays into a whole; the exhaust device 15 is provided on the top of the shell 13 so that the air in the cavity can be discharged after sealing.

[0027] Working principle: When in use, when a certain voltage or current is applied to both ends of the relay coil 6, the magnetic flux generated by the coil 6 passes through the magnetic circuit composed of the iron core 5, yoke 3, armature 4, and the working air gap of the magnetic circuit. Under the action of the magnetic field, the armature 4 is attracted to the top surface of the iron core 5, thereby pushing the normally closed contact to open and the normally open contact to close; when the voltage or current at both ends of the coil 6 is less than a certain value, the mechanical reaction force is greater than the electromagnetic attraction force, the armature 4 returns to the initial state, the normally open contact opens, and the normally closed contact connects.
