Description

Technical Field

[0001] This utility model relates to the field of permanent magnet eddy current deceleration technology, specifically a linear permanent magnet eddy current deceleration device. Background Technology

[0002] Magnetic eddy current deceleration technology utilizes a series of permanent magnets with alternating N and S poles to generate a magnetic field with alternating directions. When a moving object carrying an induction plate moves relative to the magnetic field of the permanent magnet, the induction plate cuts the magnetic lines of force to generate induced electromotive force and eddy currents. Through the interaction between the eddy current magnetic field and the magnetic field of the permanent magnet, a reverse braking force that varies with the speed is generated, thereby converting the kinetic energy of the object into heat energy on the induction plate and achieving deceleration of the object.

[0003] Existing magnetic eddy current deceleration devices typically involve mounting an induction metal on a guide rail, which not only increases the difficulty of installing the guide rail but also results in excessively high manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to provide a linear permanent magnet eddy current deceleration device to solve the problem of excessively high cost of deceleration devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linear permanent magnet eddy current deceleration device, characterized in that it comprises:

[0006] Roller;

[0007] The swing structure is fixedly mounted at one end of the roller;

[0008] The sensing structure is detachably mounted on the other end of the roller;

[0009] It also includes: a guide rail, wherein the right end of the roller is a cylindrical structure, and a keyway is provided on the front wall of the right end, and the end of the roller is threaded; the guide rail is movably mounted on the lower wall of the roller and is located at the right end of the roller.

[0010] The swing structure includes: a swing rod, a magnet, a clamping nut, and a flat key;

[0011] The swing rods are movably fitted into the cylindrical structure at one end of the roller, and the groove on the inner wall of the circular hole on the swing rod is in the same direction as the keyway on the roller. The magnet is fixedly placed on the upper wall of the swing rod and located at the center. The clamping nut is fixedly screwed onto one end of the roller and fits against the right wall of the swing rod. The flat key is movably embedded in the keyway at the right end of the roller, and its upper end is movably embedded in the groove on the inner wall of the circular hole on the swing rod.

[0012] Preferably, the right wall of the swing rod has a circular hole, and the inner wall of the circular hole has a groove.

[0013] Preferably, the width of the flat key is smaller than the width of the keyway on the roller, and its width is smaller than the width of the groove in the circular hole of the swing rod.

[0014] Preferably, the sensing structure includes: a portion of the vehicle body and a sensing metal;

[0015] One end of the vehicle body is movably fitted onto the right end of the roller, and its lower wall remains horizontal. The sensing metal is fixedly placed on the lower wall of the vehicle body and is located directly above the magnet.

[0016] Preferably, the sensing metal is a metal that can generate a turbine effect with a magnet.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: A linear permanent magnet eddy current deceleration device, through the rolling of the roller on the guide rail, drives the swing rod to rotate through the limiting action of the flat key. The swing rod is tightened by the clamping nut to prevent it from falling off during rotation. During the rotation of the swing rod, the magnet continuously passes in front of the induction metal on part of the vehicle body, generating a turbine effect, which reduces the rotation speed of the swing rod. The faster the rotation speed, the stronger the deceleration effect. By decelerating the swing rod, the roller is decelerated, so that the roller runs at a stable speed. The above structure achieves deceleration of the device and greatly reduces costs. Attached Figure Description
