Description
Technical field
The utility model is related to sports goods field, especially a kind of electromagnetic seesaw.
Background technology
Electromagnetic seesaw is electromagnetism class exhibition item common in modern city science and technology center in recent years, utilizes the polarity of electromagnet
Variation and the magnet principle that identical charges repel each other realize a kind of automatic and forever dynamic seesaw experience apparatus.Maximum experience
Enjoyment is exactly the effect that can allow one people of experiencer that can experience seesaw, and automatically " moving forever ", has very strong body
The property tested, interactivity and science popularization meaning.The core technology of electromagnetic seesaw is the stabilization of control ferromagnetic to electromagnetism and structure
Property.With more ripe and applications of the PLC in electromechanical structure of electromagnetic technique, the experience performance and stability of electromagnetic seesaw
Also it becomes better and better.Electromagnetic seesaw showpiece experience performance and stability in major science and technology center are also different.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of electromagnetic seesaw.It is above-mentioned to realize
Purpose the utility model uses following technical scheme：
A kind of electromagnetic seesaw, including seat, handle, lever, Qiang Ci, electromagnet, stepper motor, slide unit, tension spring are ridden
Plate, shell, seat are mounted on lever side, and handle is welded on the lever body of rod, and strong magnetic bolt is fixedly mounted on lever connecting rod end
End, electromagnet are mounted on slide unit, and stepper motor is surveyed one terminal bolt of tension spring by being driven axis connection electromagnet, in shell and fixed,
The other end connects lever connecting rod end, and foot pedal is welded on lever lower end.
Preferably, the stepper motor is electrically connected PLC.
Preferably, the PLC type number is Mitsubishi FX3U-32MT.
Preferably, the built-in clump weight of the package header.
Compared with prior art, the utility model has the following advantages：A kind of electromagnetic seesaw, when lever moves downward
When, strong magnet is close with electromagnet, utilizes the principle of " homopolar-repulsion ", electromagnet that can apply active force to strong magnet, push thick stick
Bar moves upwards, and completes swinging up and down for seesaw, and to ensure that enough powered levers rise, equipment is added to tension spring, even
It is connected on lever, the electromagnetic push for pushing the thrust of load level to provide not only electromagnet, also tension spring, which are shunk, to be applied
Pulling force, so that lever is easily increased.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model electromagnetic seesaw.
Fig. 2 is the appearance diagram of the utility model electromagnetic seesaw.
In figure：1, seat, 2, handle, 3, lever, 4, Qiang Ci, 5, electromagnet, 6, stepper motor, 7, slide unit, 8, tension spring, 9,
Foot pedal, 10, shell.
Specific implementation mode
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of electromagnetic seesaw, including seat 1, handle 2, lever 3, strong magnetic 4, electromagnet 5, step
Stepper motor 6, slide unit 7, tension spring 8, foot pedal 9, shell 10,1 bolt of seat are mounted on 3 side of lever, and handle 2 is welded on lever 3
On the body of rod, 4 bolt of strong magnetic is fixedly mounted on 3 connecting rod end of lever, and electromagnet 5 is mounted on slide unit 7, and stepper motor 6 passes through biography
Moving axis connects electromagnet 5, surveys 8 one terminal bolt of tension spring in shell 10 and fixes, and the other end connects 3 connecting rod end of lever, and foot pedal 9 welds
It is connected on 3 lower end of lever.
The stepper motor 6 is electrically connected PLC.
The PLC type number is Mitsubishi FX3U-32MT.
The built-in clump weight of 10 pedestal of the shell.
Utility model works principle：A kind of electromagnetic seesaw, when lever moves downward, strong magnet is leaned on electromagnet
Closely, utilize the principle of " homopolar-repulsion ", electromagnet that can apply active force to strong magnet, push lever to move upwards, completion is lifted up
Plate is swung up and down, and to ensure that enough powered levers rise, equipment is added to tension spring, is connected on lever, pushes load
The electromagnetic push that the thrust of lever provides not only electromagnet, also tension spring shrink the pulling force applied, keep lever light
Pine rises.
Electromagnet is mounted on stepper motor slide unit, program-controlled by PLC, and electromagnet is moved forward and backward, can be in different positions
Set work.Experiencer's weight is had nothing in common with each other, and the position that different people takes the decline of seesaw strong magnet is also different, to ensure electromagnetism
The electromagnetic push that iron provides effectively, it is in due course be applied on lever, equipment is mounted with sensor in electromagnet leading portion, electromagnet by
Voluntarily be moved forward and backward, when detect strong magnet close to when electromagnet just discharge electromagnetic push（The homopolarity of magnet is closer, repulsive force
It is bigger）, magnet can be in most appropriate opportunity offer electromagnetic push.
The present invention uses the pulling force that tension spring generates, and increases electromagnetism and sticks up the required power of seesaw rising, avoids market
The shortcomings that upper electromagnetic seesaw is short of power；The program-controlled moveable electromagnet of PLC, avoids in electromagnetic seesaw experience of the process
Energy attenuation and strict demand to experiencer's weight, increase experience performance and stability.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention with spirit, the change that is carried out to embodiment is repaiied
Change, replace and modification is still fallen within the scope of protection of the utility model.
