Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is described further.

[0011] Such as figure 1 As shown, an application of the principle of electromagnetic induction, including: switch 1, power supply 2, limit housing 3, ring magnet 4, coil 5, energized solenoid 6, brake lever 7, ring limit circlip 8, belt The inner wheel 9 of draw-in groove.

[0012] When the operator holds the handle, the switch 1 has been touched to turn on the circuit, a certain current will be generated, and a magnetic field will be generated in the solenoid 6, and the magnetic field at the junction of the ring magnet 4 and the solenoid 6 is the same, repelling each other, and braking The rod 7 is limited by the limit clamp spring 8 at the lower end of the solenoid 6, and the ring magnet 4 can only rise to a certain height in the limit housing 3 due to repulsion. The inner wheel 9 of the inner wheel 9 is released, so that when the handle is held by hand, the baby carriage w...

Abstract

The invention discloses application of the electromagnetic induction principle. The application of the electromagnetic induction principle comprises a switch, a power supply, a limit shell, a ring magnet, a coil, a spot galvanized solenoid, a brake lever, a ring limit snap spring and an inner wheel provided with a neck. The invention belongs to the technical field of manufacturing of baby strollers and provides the application of the electromagnetic induction principle. The magnetic effect of the current and the like pole repellant principle are utilized. The circuit is switched on when people push a baby stroller by holding the handle, the brake lever is automatically separated from a brake groove, wheels are freed, thus people can push the baby stroller freely, the circuit is switched off when the hands leave the handle, the wheels are automatically locked, and the baby stroller cannot be moved forwards. According to the device, automation is ingeniously introduced into brake devices of baby strollers, thus the national standard of baby strollers is realized, and the application of the electromagnetic induction principle has higher social value and practical significance.

Description

technical field [0001] The invention belongs to the technical field of baby trolley manufacturing, and specifically relates to the application of the principle of electromagnetic induction. Background technique [0002] Baby trolley is not only a tool cart for baby outdoor activities, but also a necessity for mothers to take their babies to the streets for shopping and leisure, so its safety, comfort and quality need special attention. I happened to see this scene on the news: a father in a certain place was taking pictures of the baby in the stroller by the lake, and at the same time, the unlocked car slid down the slope into the lake, and the father hurriedly dropped the camera and jumped into the lake , As a result, both father and son died. Such an incident made me very sad. Domestic and international standard requirements for baby carriages are: baby carriages must be equipped with braking devices. After a large number of visits and investigations and Internet access, ...
