Description

Technical Field

[0001] The utility model relates to the field of amusement equipment, in particular to a magnetic braking device for amusement equipment. Background Art

[0002] A sliding car is a common device in an amusement park, which is used for people to have fun or to view the environment along the sliding car. The sliding car is slidably connected to the main track body, so that the sliding car slides on the main track body by gravity.

[0003] In the existing patent application No. CN202210221853.2, a high-altitude non-powered sliding rail car with magnetic braking and its implementation method, two secondary pulleys are rotatably arranged between two mounting plates. Eddy current plates are arranged on both sides of each secondary pulley, and the eddy current plates are fixedly connected to the secondary pulleys by screws. A plurality of annularly arranged strong magnetic sheets are arranged on the inner sides of the two mounting plates. When the sliding car body slides, the magnetic force lines of the magnetic field formed by the plurality of strong magnetic sheets are continuously cut by the eddy current plates, so that eddy currents around the shoulder screws are generated on the eddy current plates. The magnetic field generated by the eddy currents is opposite to the magnetic field generated by the strong magnetic sheets, so as to generate a resistance force opposite to the rotation direction of the secondary pulley, playing a role in braking.

[0004] As described above, in the existing sliding car braking device, the braking force mainly depends on the vehicle speed and the magnetic field strength, the braking force cannot be accurately controlled, the flexibility is low, the structure is complex, and the manufacturing cost is high. Content of the Utility Model

[0005] The utility model provides a magnetic braking device for amusement equipment to solve the technical problems in the prior art that the braking force cannot be accurately controlled, the flexibility is low, the structure is complex, and the manufacturing cost is high.

[0006] To solve the above problems, a magnetic braking device for amusement equipment provided by the utility model adopts the following technical scheme: including a sliding car, a mounting plate, and a track. The sliding car is slidably matched with the track. An eddy current plate is arranged on the sliding car. A strong magnetic sheet is arranged on one side of the mounting plate facing the sliding car. The eddy current plate and the strong magnetic sheet correspond to each other. The distance from the strong magnetic sheet to the track gradually decreases.

[0007] Further, the mounting plate is inclined, and the distance from the mounting plate to the track gradually decreases along the direction towards the tail of the track.

[0008] Further, the mounting plate includes two groups, and the two groups of mounting plates are respectively distributed on both sides of the track, and the two groups of mounting plates are symmetrical about the track.

[0009] Further, the strong magnetic sheets on the two groups of mounting plates are arranged alternately.

[0010] Further, the material of the eddy current plate is copper.

[0011] Further, the track includes a circular part and a fixed part, and the pulley car includes a main pulley and a secondary pulley. The main pulley moves along the fixed part, and the secondary pulley moves along the outer wall of the circular part.

[0012] Further, the pulley car includes a fixing plate which is perpendicular to the track. There are two groups of the fixing plates, and the eddy current plate is abutted and connected between the two groups of the fixing plates.

[0013] The beneficial effects of a magnetic braking device for a amusement device provided by the utility model are as follows:

[0014] 1. The device uses magnetic braking, and there is no direct contact between the pulley car and the braking system, avoiding problems such as braking jamming or ineffectiveness caused by adhesion weight and adhesion coefficient, ensuring the stability and reliability of the braking performance. And because there is no mechanical friction during the braking process, no noise and dust will be generated, which is beneficial to environmental protection. At the same time, this braking method can also effectively avoid wear problems, thus extending the service life of the braking device;

[0015] 2. When the pulley car enters the range of the strong magnetic sheet, the eddy current plate cuts the magnetic field to generate resistance, so that the pulley car decelerates. And as the pulley car approaches the strong magnetic sheet, the strong magnetic field gradually increases, the eddy current effect becomes more obvious, and the resistance received by the pulley car gradually increases, so that the pulley car can decelerate smoothly until it stops during the braking process, effectively avoiding potential safety hazards caused by sudden braking or excessive deceleration;

[0016] 3. By adjusting the distance between the strong magnetic sheet and the track, the braking force can be adjusted more flexibly and directly, and then the precise control of the braking force and the precise control of the deceleration curve of the pulley car can be realized;

[0017] 4. The device has a simple structure, lower manufacturing cost and maintenance difficulty, and higher practicability. Description of the Drawings

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0027] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0028] The utility model provides a magnetic brake device for amusement equipment, such as Figures 1 to 2 As shown, it includes a pulley 1, a mounting plate 2, and a track 3. The pulley 1 and the track 3 are slidably matched. An eddy current plate 11 is provided on the pulley 1. A strong magnetic sheet 21 is provided on the side of the mounting plate 2 facing the pulley 1. The eddy current plate 11 and the strong magnetic sheet 21 correspond to each other, and the distance between the strong magnetic sheet 21 and the track 3 decreases step by step.

[0029] In this embodiment, when the eddy current plate 11 on the pulley 1 is close to the strong magnetic sheet 21 on the mounting plate 2, the strong magnetic field will induce eddy currents in the eddy current plate 11. When the eddy currents flow in the eddy current plate 11, they will be hindered by the strong magnetic field, thereby generating a braking torque. This braking torque will hinder the movement of the pulley 1 and slow it down. As the pulley 1 approaches the strong magnetic sheet 21, the strong magnetic field gradually increases and the eddy current effect becomes more obvious, ensuring that the pulley 1 decelerates smoothly during the braking process until it stops, avoiding safety hazards caused by sudden braking or excessive deceleration.

[0030] In this embodiment, the track 3 includes a circular portion 31 and a fixed portion 32. The sliding carriage 1 includes a main pulley 12 and a secondary pulley 13. The main pulley 12 moves along the fixed portion 32, and the secondary pulley 13 moves along the outer wall of the circular portion 31. There are two sets of the driving wheels and the secondary pulleys 13 respectively. The two sets of driving wheels are symmetrically distributed on both sides of the vertical central axis of the track 3, and the two sets of secondary pulleys 13 are symmetrically distributed on both sides of the vertical central axis of the track 3. Each set of secondary pulleys 13 includes two secondary pulleys 13, which are respectively located on the upper and lower sides of the circular portion 31, ensuring that the sliding carriage 1 can travel stably and reliably. In this embodiment, the eddy current interacts with the magnetic field to generate a braking torque, thereby preventing the driving wheels and the secondary pulleys 13 from rotating. As the sliding carriage 1 approaches the mounting plate 2, the strong magnetic field gradually increases, the eddy current effect becomes more obvious, and the braking torque gradually increases.

[0031] It should be noted that the installation and rotation of the main pulley 12 and the secondary pulley 13 on the sliding carriage 1 are prior arts. Those skilled in the art should be clear about their structures, principles, usage methods, etc., and no specific description will be made here.

[0032] In this embodiment, the sliding carriage 1 includes a fixing plate 14. The main pulley 12 and the secondary pulley 13 are installed on the fixing plate 14. The fixing plate 14 is perpendicular to the track 3. There are two sets of the fixing plates 14. The eddy current plate 11 is abutted and connected between the two sets of the fixing plates 14, so that the eddy current plate 11 can be firmly fixed on the sliding carriage 1, and can maintain a stable position and posture during the braking process, and can make the eddy current plate 11 face the strong magnetic sheet 21, making the magnetic force braking effect better. In other embodiments, the eddy current plate 11 can also be fixedly installed at other positions of the fixing plate 14, or the fixing plate 14 can be made of the same material as the eddy current plate 11 and capable of inducing eddy currents in a strong magnetic field, etc. As long as it can induce eddy currents in a strong magnetic field and generate a braking torque.

[0033] In this embodiment, the mounting plate 2 is inclined, and the distance between the mounting plate 2 and the track 3 gradually decreases in the direction towards the tail of the track 3. By adjusting the distance between the mounting plate 2 and the track 3, the distance between the strong magnetic sheet 21 and the track 3 is gradually decreased. In other embodiments, the distance between the strong magnetic sheet 21 and the track 3 can also be set in various forms such as gradually increasing or curvilinearly increasing and decreasing, so as to increase or decrease the braking force, thereby meeting the diverse needs of users.

[0034] In this embodiment, there are two sets of the mounting plates 2. The two sets of the mounting plates 2 are respectively distributed on both sides of the track 3, and the two sets of the mounting plates 2 are symmetric with respect to the track 3, ensuring that the braking force is evenly distributed on both sides of the sliding carriage 1 and avoiding unnecessary deflection or inclination.

[0035] In this embodiment, the strong magnetic sheets 21 on the two groups of mounting plates 2 are arranged alternately, that is, the strong magnetic sheets 21 on one side of the mounting plate 2 and the strong magnetic sheets 21 on the other side of the mounting plate 2 are staggered in position, which can form a denser magnetic field network. When the eddy current plate 11 moves in the magnetic field, it will induce a stronger eddy current, thereby generating a greater braking torque, which helps to improve the braking efficiency and response speed of the magnetic brake system. In this embodiment, on the basis of the alternating arrangement, the N poles and S poles of the strong magnetic sheets 21 are also arranged alternately, so that a magnetic field loop is formed between adjacent strong magnetic sheets 21, and the magnetic field distribution of the entire magnetic brake system is more uniform, which can effectively enhance the magnetic field strength and stability of the entire magnetic brake system, and help to reduce the vibration and shaking of the pulley 1 during the braking process.

[0036] In the present embodiment, the vortex plate 11 is made of copper, which has good thermal conductivity, corrosion resistance and mechanical strength and is highly practical.

[0037] The utility model provides a magnetic brake device for amusement equipment. The device uses magnetic braking. There is no direct contact between the pulley 1 and the braking system, which avoids the brake jam or ineffectiveness caused by problems such as adhesion weight and adhesion coefficient, ensures the stability and reliability of the braking performance, and because there is no mechanical friction during the braking process, no noise and dust are generated, which is beneficial to environmental protection. At the same time, this braking method can also effectively avoid wear problems, thereby extending the service life of the braking device; when the pulley 1 enters the range of the strong magnetic sheet 21, the eddy current plate 11 cuts the magnetic field to generate resistance, so that the pulley 1 decelerates, and as the pulley 1 approaches the strong magnetic sheet 21, the strong magnetic field gradually increases, the eddy current effect is more obvious, and the resistance of the pulley 1 gradually increases, so that the pulley 1 can be steadily decelerated until it stops during the braking process, which can effectively avoid the safety hazards caused by sudden braking or excessive deceleration; by adjusting the distance between the strong magnetic sheet 21 and the track 3, the braking force can be adjusted more flexibly and directly, thereby realizing the precise control of the braking force and the precise control of the deceleration curve of the pulley 1; the device has a simple structure, lower manufacturing cost and maintenance difficulty, and higher practicality.
