Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Please refer to figure 1 and figure 2 , providing an electromagnetic switch device 100, including a housing 1, a stator installed in the housing 1, and a mover that can move relative to the stator. The stator includes a fixed iron core 31 fixed to the housing 1 and a cylindrical The coil 2, the fixed iron core 31 is installed in the coil 2; the mover includes a moving iron core 32 located in the coil 2 and on the side of the fixed iron core 31, and the coil 2 is set on the fixed iron core 31 and the moving iron core 32 On the outer periphery, a reset elastic member 4 is connected between the fixed iron core 31 and the moving iron core 32. The coil 2 drives the moving iron core 32 to move relative to the fixed iron core 31 in the axial direction, and the reset elastic member 4 provides a restoring force for the moving iron core 32. The end face...

The present invention provides an electromagnetic switch device, comprising a housing, a stator mounted within the housing, and a rotor capable of moving with respect to the stator. The stator comprises a stationary iron core fixed to the housing and a cylindrical coil fixed within the housing, the stationary iron core being mounted within the coil. The rotor comprises a moving iron core provided within the coil and located on one side of the stationary iron core, a reset elastic member being connected between the stationary iron core and the moving iron core. The end face of the moving iron core facing the stationary iron core is provided with a first accommodating groove for accommodating one end of the reset elastic member, and the end face of the stationary iron core facing the moving iron core is provided with a second accommodating groove for accommodating the other end of the reset elastic member. The electromagnetic switch device further comprises a connecting member connected to the moving iron core and having a tail end extending to the outer side of the housing to connect an external device, the connecting member generating a displacement under the drive of the moving iron core. The electromagnetic switch device provided by the present invention features a simple structure, simple part processing and assembling, and low costs.
Description
【Technical field】 [0001] The invention relates to the field of electronic equipment, in particular to an electromagnetic switch device applied to mobile terminal equipment. 【Background technique】 [0002] At present, in the mobile phone industry, the lifting function of the internal components of the mobile phone is realized by the module of stepping motor, reducer, and transmission screw pair; its working principle is: the protruding gear shaft of the stepping motor meshes with the gear of the reducer, and the motor rotates at high speed , The torque is transmitted to the reducer through the gear to realize the speed reduction and increase the torque. The rear end of the reducer is connected with the screw pair to convert the rotary motion into a linear motion. The nut on the screw pair moves linearly to drive the internal components to rise and fall. There are deficiencies and disadvantages in this existing lifting scheme: the structure of the module is complicated, the pr...
