Description

Rotary electromagnetic solenoid

The present invention belongs to the technical field of electromagnetic solenoids, and particularly relates to a new designer of a rotary electromagnetic solenoid, which has the convenience of simplifying the structure and assembly of the rotary electromagnetic solenoid.

Press, the magnetic field can be generated after power-on, and the conductive coil for external work is called a solenoid. It is an active part that converts electrical energy into magnetic energy and further transforms it into mechanical energy. The rotary electromagnetic solenoid can be applied to various uses for repeatedly rotating the shaft over a predetermined angular range.

In the prior art, Japanese Patent Laid-Open No. Hei 11-178306, the rotary solenoid patent (referenced on July 2, 1999), is provided with a shaft portion that is rotatably supported by a housing; a movable portion, One end is fixed to the shaft portion, and the other end is a free end, and the movable portion has a magnet; and a pair of electromagnetic coil portions having a core fixed to the housing and disposed at a predetermined interval Both sides of the movable direction of the portion are selectively attracted to the movable portion by energization control. However, in this case, since the electromagnetic coil portions having the coil and the iron core are separately disposed on both sides of the movable portion having the magnet, the number of components constituting the entire electromagnetic coil portion requires two coils and two iron cores. Therefore, an increase in the number of components of the entire rotary solenoid causes an increase in the cost of the component, and an increase in the manufacturing cost due to an increase in the number of assembly man-hours is absent. Also, China CN 1503438 rotary solenoid patent, which includes one a rotor having a core axis; at least two permanent magnets are mounted on the rotor, and a polar axis of the permanent magnet is located at a predetermined angular position about a central axis; a stator is disposed around the rotor; the stator includes a pole piece, the number of pole pieces and a permanent magnet The number is matched; a coil is wound on each pole piece; the pole axis of the pole piece is located at a predetermined angular position about the central axis; the rotor is magnetically induced by the induced current in the coil and the permanent magnet within a predetermined angular range Magnetic field drive. In the prior case, the increase in cost due to the increase in the number of at least two permanent magnet members, and the increase in the assembly time of the stator setting coil also caused an increase in manufacturing cost, etc., which was absent.

Furthermore, when the vehicle is in poor visibility (for example, at night, in a tunnel, in rainy weather, in dense fog, or in a bad climate), it is necessary to provide a vehicle lamp because it affects the driving safety of the vehicle. Moreover, in order to meet the needs of the vehicle driver in the field of view illumination, the vehicle lights have the function of switching between the high beam and the low light. The conventional lamp is provided with a switching function of a remote lamp and a close lamp, and a reflector surface is provided inside the lamp device to provide a lamp source and a lamp function, respectively, but There must be two mirrors and two light sources, which are costly. Therefore, they have long been abandoned by the lamp manufacturers. Then, the operator designs a switching function of a single lamp source, a single mirror surface, and a switching mechanism to achieve a far-light and a near-light, as disclosed in US Patent Publication No. 20030165066, European Invention Patent No. 1010935, and Chinese Patent No. I383906. No., No. M361442, etc., which uses a solenoid valve to cooperate with the power shaft of the solenoid valve as a linear motion before and after, and drives a linkage mechanism to shift a visor up and down. The source is projected by the reflection of the mirror surface to project bright light outward. When the outward projection range is partially blocked by the visor, the illumination mode of the low beam is formed. When the Shield is covered, the reflection light is enlarged to expand the reflected light. The area of the diffusion can expand the range and distance of the outwardly projected light to form the illumination mode of the high beam. Take China's patent as an example: the bulletin number M486576 can be adjusted The illumination angle of the vehicle (refer to the patent publication on September 21, 2014) is mainly composed of a light-emitting element, a lamp holder, a fixing ring, a lamp cover and an actuation module, and the light-emitting element is disposed inside the lamp holder; The fixing ring is connected to the lamp holder; the lamp cover comprises a lens and a lamp cover ring, the lens system is fixed on the lamp cover ring, and the lamp cover ring is movably connected to the fixing ring; the actuation module comprises a push rod and a push rod actuator, and the push rod Provided around the fixing ring, the push rod actuator is disposed on the fixing ring corresponding to the position of the push rod, and the push rod actuator can be used to actuate the push rod so that the lamp cover rotates relative to the lamp holder, and the push rod actuator A stepper motor or a drive motor can be included. Bulletin No. M485842 is a lamp device with a near-light switch of LED light source (refer to the patent announcement on September 11, 2014), which is mainly provided with a lamp holder in the lamp housing of the lamp, in the lamp holder The light-emitting end face is provided with a light-emitting LED light source facing the upper end surface of the inner edge of the lamp housing, and an upper end surface of the inner edge of the lamp housing corresponds to an optical reflection surface of the near-light LED light source, and the lamp housing corresponds to the lamp socket. The outer side of the light source is provided with a light shielding plate, so that the light of the near-light LED light source can only be transmitted outwardly from the top edge of the light shielding plate, and the outer side end surface of the light shielding plate is provided with a high-light lamp holder. At least one LED light source is provided, and the lamp housing is covered with a lamp cover, and the outer end of the lamp cover is provided with a lens for transmitting light. As can be seen from the foregoing, the conventional vehicle lamp remote control device has many components, is troublesome to assemble, and is time consuming, troublesome, and has high manufacturing cost, and is lacking. How to provide components with streamlined, quick and efficient assembly, and to effectively reduce costs and improve economic efficiency, is a difficult problem to be overcome in the industry.
