Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic brakes, in particular to a magnetic brake device. Background Art

[0002] Electromagnetic brakes are mechanical devices that stop or slow down moving parts in machinery. They have the advantages of compact structure, simple operation, sensitive response, reliable use, and easy control. During driving, magnetic brakes can assist in braking. Magnetic brakes are made of one or two long strips of neodymium magnets with strong magnetic force. When a metal sheet (usually copper or copper-aluminum alloy) cuts the magnetic flux lines, eddy currents are generated inside the metal, which will generate a magnetic field to resist movement. The resulting braking force is proportional to the speed at which the metal sheet moves inside the magnet, generating heat energy at the same time. This magnetic braking effect can be interpreted as gradually halving the speed of the train according to a certain rule. However, when the speed is reduced to a certain level, the eddy currents generated are not enough to stop the train, which requires friction brakes or friction drive wheels. Friction brakes are mostly used in amusement park equipment, and most existing friction brakes only increase the friction force by strengthening the contact force through magnetic drive.

[0003] A magnetic brake device with publication number CN220435287U is provided with an electromagnet at the end face of a metal brake disc, and the magnetic force generated by the electromagnet when it is energized directly attracts the metal brake disc, so that the resistance generated by the magnetic force can directly brake, decelerate or stop the metal brake disc. Therefore, the electromagnetic brake is directly applied to the metal brake disc of the vehicle, which can reduce the cost of electromagnetic braking and ensure the braking effect. By providing an angle adjustment structure, the orientation of the electromagnetic magnetic field surface can be flexibly adjusted, so as to change the orientation of the electromagnetic magnetic field surface, and avoid the residual weak magnetism after the electromagnet is powered off, which affects the movement of the vehicle. However, its structure still needs to be improved. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic brake device, including a brake track, a brake disc body is arranged inside the brake track, and a plurality of limit plates for limiting the brake disc body are connected to both sides of the top of the brake track, one side of the brake disc body is provided with an external bracket, and a magnetic magnet is installed on the side of the external bracket close to the brake disc body, the magnetic end of the magnetic magnet is connected to a conductive column, and the end of the conductive column is in a nearly fitting position with one side of the brake disc body, friction plates made of metal are arranged on both sides of the inner periphery of the brake track on the brake disc body, and a resistance increasing part for increasing friction is arranged on the adjacent side of the two friction plates, a plurality of triangular grooves are opened on the outer periphery of the brake disc body, and a resistance increasing block is arranged on the inner bottom of the brake track.

[0006] In a further embodiment, a plurality of heat dissipation cavities for heat dissipation are provided on the outer side of the brake disc body, and a disc brake system for friction braking is provided on the brake disc body.

[0007] In a further embodiment, a plurality of inner cavities are formed at the inner bottom of the brake track, and the inner periphery of the inner cavity and the resistance-increasing block are designed to slide in a limited position.

[0008] In a further embodiment, the plurality of triangular grooves on the outer periphery of the brake disc body are distributed in a ring array, and the triangular grooves are matched with the ends of the resistance-enhancing blocks.

[0009] In a further embodiment, the end of the resistance-increasing block is designed with a slope on one side, and the end and the triangular groove are adapted to form a right triangle structure.

[0010] In a further embodiment, a tenon rod and a tenon sleeve are provided on a side of the friction plate away from the brake disc body, and the end of the tenon rod and the tenon sleeve are mortise-joined with each other.

[0012] In a further embodiment, circular cavities are formed at both ends of the friction plate, and guide posts fixed to the inner wall of the brake track are provided on the inner circumference of the circular cavity.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The design of the brake disc body being located inside the brake track and the design of the brake disc body being limited by multiple limit plates on both sides of the top of the brake track can improve the stability of the brake. With the operation of the magnetic iron, the magnetic attraction and conduction between the conductive column and the brake disc body can further strengthen the contact force between the brake disc body and the brake track, thereby strengthening the resistance and cooperating with the operation of the disc brake system to greatly improve the braking effect.

[0015] The magnetic attraction of the magnetic iron can attract the metal around the brake disc body, further attract the friction plate and the brake disc body to fit together, thereby increasing the friction force. At the same time, it will attract the adjacent resistance-enhancing block, so that the end of the resistance-enhancing block will rise to the triangular groove. Combined with the inclined surface design of the resistance-enhancing block, it will further generate resistance and then be pressed into the inner cavity along the inclined surface, achieving another resistance friction, further improving the braking effect.

[0016] Compared with the comparison device, the magnetic brake device can greatly improve the braking effect by increasing the friction through the friction plate and the resistance increasing block. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0028] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0029] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0030] See also Figures 1 to 5 The general structure of the device body includes a brake track 1 and a brake disc body 2. The brake disc body 2 is located at the inner circumference center of the brake track 1. A plurality of limit plates 4 are connected to both sides of the top of the brake track 1. The limit plates 4 are fixed to the top of the brake track 1 by bolts. The limit plates 4 on both sides are designed to fit closely with the sides of the brake disc body 2, thereby achieving the function of limiting. The bolt connection design is also convenient for dismantling and maintaining the interior. A plurality of heat dissipation cavities are opened on the outer side of the brake disc body 2. A disc brake system 3 is arranged on the brake disc body 2. The disc brake system 3 adopts the existing technology, so it will not be described here.

[0031] An external bracket 6 is provided on the outside of the brake disc body 2. The external bracket 6 is made of a material that will not be attracted by magnetic force. A magnetic attractor 7 is installed on one side of the external bracket 6. The magnetic end of the magnetic attractor 7 is connected to a conductive column 8. The end of the conductive column 8 is in a position close to the one side of the brake disc body 2. When the magnetic attractor 7 is running, the magnetic attraction can be further transmitted to the brake disc body 2 through the conductive column 8. The conductive column 8 is made of a material that can be affected by magnetic force.

[0032] See also Figure 1 , Figure 2 and Figure 5 In order to increase friction, metal friction plates 5 are arranged on both sides of the brake disc body 2 on the inner circumference of the brake track 1. The two friction plates 5 are symmetrically designed, and the centers of the two friction plates 5 on the sides away from each other are both provided with tenon rods 21 and tenon sleeves 22;

[0033] The tenon sleeve 22 is fixed to the inner wall of the brake track 1. The tenon sleeve 22 and the tenon rod 21 are designed to be mutually tenoned. The tenon rod 21 is arranged on the inner periphery of the tenon sleeve 22 and a limiting portion is arranged. An elastic member is arranged between the limiting portion and the inner periphery of the tenon sleeve 22. The elastic member can be a spring, an elastic rope, etc. The elastic force of the elastic member is much smaller than the magnetic attraction force, so that when not affected by the magnetic attraction force, the friction plate 5 will not contact the brake disc body 2.

[0034] In order to improve stability, circular cavities are formed at both ends of the friction plate 5 , and a guide column 23 is provided on the inner circumference of the circular cavity. The guide column 23 is adapted to the circular cavity, and one end of the guide column 23 is connected to the inner wall of the brake track 1 .

[0035] See also Figure 1 , Figure 4 and Figure 5 In order to increase friction again, the inner bottom of the brake track 1 has multiple inner cavities 31, and the inner periphery of the multiple inner cavities 31 is limited and slid with resistance-increasing blocks 32, which are made of metal material. The outer periphery of the brake disc body 2 is provided with multiple triangular grooves 33, and the multiple triangular grooves 33 are distributed in a ring array with the brake disc body 2 as the center;

[0036] The end portion is adapted to the triangular groove 33 as a right triangle structure, the interior of the triangular groove 33 is designed as a triangular cross-section, the end portion of the resistance increasing block 32 is designed as a slope on one side, the sloped end portion of the resistance increasing block 32 is adapted to the triangular groove 33 as a right triangle structure, and the end portion of the resistance increasing block 32 is located inside the inner cavity 31 and is provided with a resistance head portion.

[0037] The above-mentioned components and electrical equipment are all existing technologies or existing feasible technologies. The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0038] How it works

[0039] When the magnetic brake device is needed, the magnetic magnet 7 is activated to cooperate with the conductive column 8 to further conduct the strong magnetic force to the brake disc body 2;

[0040] The strong magnetic force attracts the friction plates 5 on both sides, and the friction plates 5 approach the brake disc body 2 and fit with it, thereby increasing the friction force;

[0041] The strong magnetic force will also attract the resistance increasing block 32 near the brake disc body 2 to move upward, so that the resistance increasing block 32 and the triangular groove 33 produce blocking friction. When the brake disc body 2 moves due to the inclined design, the resistance increasing block 32 will be pressed into the inner cavity 31, further increasing the friction.

[0042] At the same time, the operation of the disc brake system 3 realizes multiple frictions and achieves the braking effect.
