Embodiment 1

[0039] Embodiment one: if figure 2 The air holes corresponding to the upper and lower sides of the moving plate in the shown embodiment are all small air holes, and the air holes with small apertures make the gas flow rate that enters or exits the cylinder body instantaneously small, slows down the moving speed of the moving plate in the cylinder body, and plays an important role. Buffer function to prevent noise from collision;

[0040] When the cylinder is driven up by the guide shaft, the chamber above the moving plate is inflated, and the hot air in the housing enters the cylinder from the air hole. Since the housing is not a sealed structure, the cold air can be directly supplied from the outside of the housing to enter the housing;

[0041] A sealing ring is set on the outer circumference of the cylinder to ensure that the upper and lower chambers in the cylinder are isolated from the airflow movement without affecting the heat dissipation effect. The chamber below the ...

Embodiment 2

[0043] Embodiment two: if image 3 As shown, the air hole 81 corresponding to the upper side of the moving plate 91 is provided with a first check valve 82, and the axial center of the piston rod 9 is provided with an exhaust channel 92 axially penetrating. 92 is provided with a second one-way valve 93, the exhaust passage 92 communicates with the through hole 71, the moving plate slides up and down, the chambers on the upper side of the moving plate are inflated and exhausted respectively, and the air hole is responsible for one-way air intake , the exhaust channel is responsible for one-way exhaust, which discharges the heat generated by the coil in the shell to the outside, and because the whole shell is not a sealed structure, the cold air outside can be driven into the shell by the negative pressure in the shell, realizing The hot and cold air flow is exchanged to achieve the effect of heat dissipation during the suction and reset work.

Abstract

The invention discloses an electromagnet device for an automobile gear lock, and relates to automobile equipment. The electromagnet device comprises a housing and an upper cover, and further comprisesa fixed mandrel, a movable mandrel and a lower cover, wherein a spool and a coil which peripherally winds the spool are arranged in the housing; the fixed mandrel is fixedly mounted on the centre position of the bottom of the housing; the movable mandrel penetrates through the housing and the fixed mandrel, and separately extends out from upper and lower ends of the housing; the lower cover is detachably mounted at the outer side of the bottom of the housing, and covers the lower end of the movable mandrel; an elastic part which abuts against the movable mandrel and the fixed mandrel is arranged between the movable mandrel and the fixed mandrel; and the lower end of the movable mandrel is equipped with a damping mechanism for buffering and reducing noises. The electromagnet device has theadvantages of reducing noises, being good in heat dissipation effect and long in service life.

Description

technical field [0001] The invention relates to equipment for vehicles, in particular to an electromagnet device for a gear lock of an automobile. Background technique [0002] Electromagnets are widely used in many fields such as heavy industry, light industry, communication industry and transportation industry in our daily life, and there are more and more electromagnets for vehicles, such as: motors, generators, relays, solenoid valves, permanent Magnets, etc. all reflect the necessity of electromagnets. Therefore, the improvement of the overall performance of the electromagnet has also become an industrial trend. While pursuing quality and functions, reducing noise has also become a hot topic, especially for automotive electromagnets that require reliability and are also very sensitive to noise. requirements. [0003] After the electromagnet used in the gear lock of the car is energized and working, the movable mandrel inside the electromagnet contacts and collides wit...
