[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: an automobile charging and exhaust solenoid valve with a connection structure, comprising a valve body 1 and two shells 2 mounted on the valve body 1. Electromagnetic components are provided in the two shells 2 for respectively controlling charging and exhausting. The electromagnetic components are prior art and are therefore not described in detail. An input port 6, an output port 7 and a discharge port 8 are respectively provided on the valve body 1. The input port 6 can be connected to a medium, and the output port 7 can be used to discharge the medium. If the medium is air, the discharge port 8 does not need to be connected to a pipe. A terminal 3 is fixedly connected to the shell 2, a wire 4 is fixedly connected to the terminal 3, and a terminal 5 is fixedly connected to the wire 4.

[0018] The valve body 1 is integrally cast, and the two solenoid valve bodies are cast into a whole, which has the advantages of long service life, fast filling and exhaust speed, and good stability.

[0019] Among them, the inner walls of the input port 6 and the output port 7 are both provided with internal threads 9, so that the pipe with a joint can be directly connected to the valve body 1, and the joint thread of the pipe can cooperate with the internal thread 9, so that the pipe can be connected to the input port 6 and the output port 7. The input port 6 and the output port 7 are both provided with a connection structure for taking over the pipe, so that the pipe without a joint can also be directly connected to the valve body 1.

[0020] Among them, the connection structure includes a connecting seat 10, a connecting seat 10 is provided on the valve body 1, a threaded plate 11 is provided on the connecting seat 10, a sealing pressure ring can be provided on the inner side of the threaded plate 11, and a fixing ring 13 is movably connected to the outer side of the threaded plate 11, and the fixing ring 13 can be threadedly connected to the threaded plate 11. A pipe joint 12 for docking with the pipeline is provided in the valve body 1, and the pipe joint 12 can be connected with the input port 6 and the output port 7, and the caliber of the pipe joint 12 can be manufactured according to the use requirements. The pipeline without a joint can be inserted into the pipe joint 12, and then the threaded plate 11 is squeezed by twisting the fixing ring 13, so that the threaded plate 11 presses the pipeline tightly, thereby fixing the pipeline and the pipe joint 12.

[0021] The threaded plates 11 are arranged on the connecting seat 10 in a circular array, and the number of the threaded plates 11 can be changed as needed.

[0022] It is worth mentioning that the working voltage of the solenoid valve is 18V~32V, the release voltage is 1V~6.5V, and under the voltage of 24V, the working current of the solenoid valve is not more than 0.8A. It can work reliably within the pressure range of 300KPa~1200KPa, and there is no air pressure leakage. When the power is cut off, the peak voltage at both ends of the coil is not more than 60V.

[0023] Specifically, when the pipeline has a threaded joint, the joint thread of the pipeline can cooperate with the internal thread 9, so that the pipeline can be connected to the input port 6 and the output port 7. When the pipeline does not have a threaded joint, the pipeline can be inserted into the pipeline joint 12, and then the threaded plate 11 is squeezed by twisting the fixing ring 13, so that the threaded plate 11 presses the pipeline tightly, thereby fixing the pipeline and the pipeline joint 12.
