Description

Technical Field

[0001] This utility model relates to the field of entertainment equipment, and in particular to an electromagnetic spring-type dance machine. Background Technology

[0002] Traditional dance machines typically provide rhythm through the vibration of springs, but their limitation lies in the fixed spring constant. In actual use, when people of different weights stand on the metronome, the spring compression varies due to weight differences, resulting in inconsistent metronome amplitude. Larger individuals cause the spring to be too long, leading to excessively large amplitudes; smaller individuals cause the spring to be too short, resulting in insufficient amplitudes. This instability in amplitude not only affects the user experience but can also potentially lead to injury. Furthermore, traditional dance machines usually lack the ability to synchronize with music or video, failing to provide users with a more intuitive and engaging entertainment experience.

[0003] Active dance machines have appeared on the market, but these machines still have shortcomings. They actively propel the platform up and down using motors and cylinders, while people standing on the platform passively receive the exercise, resulting in poor comfort. Utility Model Content

[0004] This invention aims to solve the aforementioned problems by designing an electromagnetic spring-type dance machine. It uses electromagnetic force to counteract the compression or stretching of the spring by users of different weights, ensuring the spring remains within a fixed amplitude range. Furthermore, it utilizes ambient lighting to synchronize the music rhythm with visual effects. This enhances the comfort, fun, and safety of the dance machine.

[0005] The present invention adopts the following technical solution:

[0006] An electromagnetic spring-type dance machine includes a housing with an opening at the top, into which a support plate is installed. At least three linear bearings are located on the bottom wall of the housing. Guide columns are vertically movable at the top of each linear bearing, and the top of the guide columns is connected to the support plate. A tension / compression spring is fitted around the outer side of each linear bearing to elastically press against the support plate. The machine also includes a permanent magnet core, an electromagnetic coil, a laser displacement sensor, and a controller. The permanent magnet core is fixed to the bottom of the support plate. A mounting frame is located at the bottom of the housing, and the electromagnetic coil is mounted on the mounting frame. The permanent magnet core is inserted into the electromagnetic coil. The laser displacement sensor is connected to the bottom wall of the housing and faces the support plate. The controller is connected to the electromagnetic coil and the laser displacement sensor.

[0007] Furthermore, the aforementioned fixing bracket is provided with a guide hole for aligning with the aforementioned permanent magnet core, and an electromagnetic lock for preventing the permanent magnet core from moving downward is installed on the edge of the guide hole.

[0008] Furthermore, multiple light grooves are provided on the aforementioned support plate, and light strips are placed inside the light grooves. Tempered glass is stacked on the top surface of the support plate.

[0009] Furthermore, the surface of the tempered glass is covered with a light-transmitting, non-slip coating.

[0010] Furthermore, a switching power supply is provided on the side wall of the aforementioned mounting bracket.

[0011] Furthermore, the controller is equipped with a socket for connecting other dance machines in series.

[0012] Furthermore, the upper end of the aforementioned housing is provided with an outwardly extending pedal.

[0013] Furthermore, the aforementioned laser displacement sensor is connected to a bracket, which is connected to the bottom wall of the aforementioned housing by screws.

[0014] Furthermore, adjusting nuts are provided at the four corners of the bottom of the aforementioned housing.

[0015] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0016] 1. The dance machine of this application cleverly combines electromagnetic force and spring force. A laser displacement sensor monitors the displacement of the upper support plate in real time, accurately calculating the user's weight. Based on the weight data, the controller automatically adjusts the current of the electromagnetic coil, matching the upward thrust generated by the permanent magnet core and the electromagnetic coil to the user's weight. This process effectively counteracts the effects of different weights on spring compression or stretching, ensuring the spring always operates within a fixed amplitude range, providing users with a stable and comfortable jumping experience. Regardless of the user's weight, they can enjoy a consistent exercise effect.

[0017] 2. The upper support plate of the device in this application is scientifically designed. Its front-to-back width is adapted to the length of an adult's foot, and its left-to-right width matches the shoulder width of an adult. Furthermore, it is lower than the upper plane of the fixed frame formed by the surrounding front and rear pedals and left and right pedals, creating a natural jumping area and activity space. When the user stands on one leg, causing the upper support plate to press down significantly, this design prevents loss of balance, allowing the other foot to be quickly placed on the fixed frame to avoid falling, effectively improving the stability and safety of the exercise.

[0018] 3. The dance machine of this application is equipped with light strips that integrate with the music rhythm or dance movements. The controller has multiple built-in dance modes, which users can freely select via a mobile app. During the dance, the light strips will display corresponding content in real time according to the music rhythm and the amplitude of the dance movements, such as dynamic melody scores, bringing users a dual feast for the eyes and ears, making the dance process more interesting, fully releasing physical and mental emotions, and significantly enhancing the entertainment and interactivity of the device.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Reference Figures 1-3 An electromagnetic spring-type dance machine includes a housing 1 with an opening 10 at the top. A support plate 2 is disposed within the opening 10. At least three linear bearings 3 are disposed on the bottom wall of the housing 1. Guide columns 31 are vertically movable on the top of the linear bearings 3, and the guide columns 31 move up and down within the limited range of the linear bearings 3. The top of the guide columns 31 is connected to the support plate 2. Preferably, four linear bearings 3 are disposed on the bottom wall of the housing 1, and the four guide columns 31 are connected to the four corners of the support plate 2. Through the cooperation of the guide columns 31 and the linear bearings 3, the support plate 2 is prevented from tilting forward, backward, left, or right, ensuring that the upper support plate 2 can only move up and down. A tension / compression spring 32 is sleeved on the outside of the linear bearings 3 for elastically pressing against the support plate 2. The elastic force of the tension / compression spring 32 restoring its deformation causes the support plate 2 to rise to its maximum height.

[0026] Continue to refer to Figures 1-3It also includes a permanent magnet core 23, an electromagnetic coil 24, a laser displacement sensor 4, and a controller 5. The permanent magnet core 23 is fixed to the bottom of the support plate 2. A fixing frame 12 is provided at the bottom of the housing 1. The fixing frame 12 is in the shape of a door frame. The electromagnetic coil 24 is installed on the fixing frame 12. The permanent magnet core 23 is inserted into the electromagnetic coil 24. The electromagnetic coil 24 is fixed on the fixing frame 12. After the electromagnetic coil 24 is energized, an upward magnetic field is generated in the axis of the electromagnetic coil 24. The magnetic poles of this magnetic field are opposite to those of the permanent magnet core 23. The magnetic field generates an upward thrust by repelling each other through the same magnetic poles. This force acts on the downward gravity when a person stands on the support plate 2. When a person stands on the tempered glass 22 and exerts downward pressure on the support plate 2, the tension spring 32 bears part of the upward reaction force. The laser displacement sensor 4 is connected to the bottom wall of the housing 1 and faces the support plate 2. The laser displacement sensor 4 is used to monitor the height and amplitude of the support plate 2 in real time and transmit the signal to the controller 5. The controller 5 is connected to the electromagnetic coil 24 and the laser displacement sensor 4. The controller 5 issues an instruction to the electromagnetic coil 24 to work according to the signal transmitted by the laser displacement sensor 4. The permanent magnet core 23, the electromagnetic coil 24, the laser displacement sensor 4 and the controller 5 work together to make the dance machine counteract the compression or stretching of the spring by users of different weights, so that the spring is always kept within a fixed amplitude range.

[0027] Reference Figure 2 , Figure 3 The aforementioned fixing frame 12 is provided with a guide hole aligned with the aforementioned permanent magnet core 23. When the lower end of the aforementioned permanent magnet core 23 descends, it passes through the guide hole. An electromagnetic lock 121 is installed on the edge of the guide hole to prevent the permanent magnet core 23 from moving downward. When the dance machine stops working, the electromagnetic lock 121 locks the aforementioned permanent magnet core 23 to prevent people from jumping on the support plate 2 and squeezing and damaging the bottom electromagnetic coil 24.

[0028] Reference Figure 2 The support plate 2 is provided with multiple light slots 20, preferably ten light slots 20. Light strips 21 are placed in the light slots 20. The light strips 21 are used to display the amplitude pattern of music rhythm. Tempered glass 22 is stacked on the top surface of the support plate 2. The tempered glass 22 is used for people to stand on and jump.

[0029] The surface of the tempered glass 22 is covered with a light-transmitting, anti-slip coating (not shown in the figure). This coating prevents people from slipping on the tempered glass 22 while ensuring that people can see the light signal display of the light strip 21. The light strip 21 is connected to the controller 5, and the controller 5 sends commands to the light strip 21 to adjust its brightness in sync with the rhythm of the music concert.

[0030] Reference Figure 3 The aforementioned mounting bracket 12 has a switching power supply 122 on its side wall. When in use, the switching power supply 122 can be turned on or off through the through hole in the wall of the housing 1.

[0031] The front-to-back width of the aforementioned support plate 2 is 35cm, which matches the foot length of an adult. The left-to-right width of the support plate 2 is 60cm, which matches the shoulder width of a grown adult. It is also lower than the footplate 11, forming a natural jumping area and activity space.

[0032] Reference Figure 3 , Figure 4 The controller 5 is equipped with a socket 51 for connecting other dance machines in series. The dance machines can be connected in series through the data cable to the socket 51 and put together to form a large stage, bringing a better experience to the user.

[0033] Reference Figure 1 The upper end of the aforementioned housing 1 is provided with an outwardly extending foot pedal 11. When an imbalance occurs, the person's other foot can be quickly placed on the fixed frame 12 to prevent falling from the tempered glass 22 plate, thus providing a safety protection function.

[0034] Reference Figure 2 The laser displacement sensor 4 is connected to a bracket 41, which is connected to the bottom wall of the housing 1 by screws. The laser displacement sensor 4 is detachable for easy maintenance.

[0035] Reference Figure 3 The four corners of the bottom of the housing 1 are provided with adjusting nuts 13. The adjusting nuts 13 are used to adjust the height of the corners so that the dance machine can stand stably on uneven ground and people can find their balance more easily when standing on the dance machine.

[0036] Reference Figures 1-3 In the aforementioned dance machine, when a person stands on the support plate 2, the laser displacement sensor 4 detects the downward displacement of the support plate 2 and transmits the signal to the controller 5. The controller 5 connects the electromagnetic coil 24 and the laser displacement sensor 4. Based on the signal transmitted by the laser displacement sensor 4, the controller 5 issues a command to the electromagnetic coil 24 to operate. The controller 5 converts this signal into the person's weight, adjusts the current of the electromagnetic coil 24, and generates an upward thrust in the iron core. Combined with the upward thrust generated by the compressed spring, the balance point is adjusted to a suitable position. When the person's feet exert downward force, an up-and-down swaying effect is produced, and the amplitude of the swaying is related to the force exerted. The up-and-down movement amplitude of the dance machine is controlled by the tension and compression springs 32. However, since the weight range of a person is between 40KG and 110KG, and the elastic coefficient of the spring is a fixed value, the range of motion of the spring is limited. By using an auxiliary controllable electromagnetic force, the individual weight difference is offset, so that the range of motion of the spring is kept at a comfortable level. The upper surface of the dance machine is equipped with an ambient light strip 21, which is combined with the dance amplitude or music melody. The controller 5 has a variety of dance modes. After the user selects a mode through the mobile APP, the light strip 21 displays the corresponding content.

[0037] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
