The vehicle electronic expansion valve comprises a valve seat and a shell, a valve element, a rotor, a nut and a hollow screw are arranged in the shell, the nut is fixedly connected with a connecting sleeve, the nut is connected with the hollow screw in a threaded fit mode, the hollow screw is fixedly connected with the rotor, the hollow screw is arranged on the outer side of the valve element in a sleeving mode, and a spring is arranged between the valve element and the hollow screw. A linear guide module is arranged in the shell and comprises a guide assembly and a displacement assembly which are in sliding fit, the guide assembly is arranged on the inner wall of the shell in the mode of extending in the axial direction of the valve element, the displacement assembly is connected with the valve element, and the stroke length of the linear guide module corresponds to the target stroke length of the valve element. The structure is simple, stopping of the rotor can be stably achieved, and noise caused by strenuous vibration of the rotor in the stopping process is avoided.

    本发明公开了一种车用电子膨胀阀,其包括阀座、壳体,壳体内设置有阀芯、转子、螺母和中空螺杆,螺母与连接套固接,螺母螺纹配合连接中空螺杆,中空螺杆与转子固接,中空螺杆套装于阀芯外侧,阀芯和中空螺杆之间设置有弹簧,壳体内设置有直线导向模组,直线导向模组包括滑动配合的导向组件和位移组件,导向组件沿阀芯轴向延伸的设置于壳体的内壁上,位移组件与阀芯连接,直线导向模组的行程长度与阀芯的目标行程长度相对应。本发明不仅结构简单,而且能够稳定的实现转子的止挡,避免转子在止挡过程中发生剧烈震动从而带来噪音。
