Description

Technical Field

[0001] The invention relates to the field of entertainment equipment, in particular to an electromagnetic spring type dancing machine. Background Art

[0002] Traditional dance machines usually provide a sense of rhythm through the vibration of springs, but their limitation is that the elastic coefficient of the spring is fixed. In actual use, when people of different weights stand on the metronome, the compression of the spring will change due to the difference in weight, resulting in different amplitudes of the metronome. Larger people will cause the spring to be too long and the amplitude of the metronome to be too large; smaller people will cause the spring to be too short and the amplitude of the metronome to be insufficient. This problem of unstable amplitude not only affects the user experience, but may also cause human injury. In addition, traditional dance machines usually lack the function of synchronous display with music or video, and cannot provide users with a more intuitive and interesting entertainment experience.

[0003] Active dance machines are available on the market, but they still have some shortcomings. They actively push the platform up and down through motors, cylinders, etc., and people standing on the platform passively accept the movement, which makes the comfort level poor. Summary of the invention

[0004] The present invention aims to solve the above problems and designs an electromagnetic spring dance machine, which uses electromagnetic force to offset the compression or extension of the spring by users of different weights, so that the spring is always kept within a fixed amplitude range, and realizes the function of synchronous display of music rhythm and visual effects through the atmosphere light belt, thereby improving the comfort, fun and safety of the dance machine.

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

[0006] An electromagnetic spring dance machine comprises a shell, an opening is provided at the top of the shell, a support plate is provided in the opening, at least three linear bearings are provided on the bottom wall of the shell, a guide column is provided on the top of the linear bearing so as to be liftable, the top of the guide column is connected to the support plate, a tension and compression spring is sleeved on the outer side of the linear bearing for elastically connecting the support plate, and the machine also comprises 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 above-mentioned support plate, a fixing frame is provided at the bottom of the shell, the electromagnetic coil is installed on the fixing frame, the permanent magnet core is inserted into the electromagnetic coil, the laser displacement sensor is connected to the bottom wall of the shell and faces the support plate, and the controller connects the electromagnetic coil and the laser displacement sensor.

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

[0008] Furthermore, a plurality of light troughs are provided on the support plate, light strips are placed in the light troughs, and 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-transmissive anti-slip coating.

[0010] Furthermore, a switching power supply is provided on the side wall of the fixing frame.

[0011] Furthermore, the controller is provided with a socket for serially connecting other dance machines.

[0012] Furthermore, a pedal extending outward is provided at the upper end of the shell.

[0013] Furthermore, the laser displacement sensor is connected to a bracket, and the bracket is connected to the bottom wall of the shell through screws.

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

[0015] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages:

[0016] 1. The dance machine of the present application cleverly combines electromagnetic force and spring force, monitors the displacement of the upper support plate in real time through a laser displacement sensor, and accurately calculates the user's weight. The controller automatically adjusts the electromagnetic coil current based on the weight data so that the upward thrust generated by the permanent magnet core and the electromagnetic coil matches the user's weight. This process effectively offsets the effect of different weights on the compression or extension of the spring, ensuring that the spring always works within a fixed amplitude range, providing users with a stable and comfortable jumping experience, and enjoying consistent exercise effects regardless of the user's weight.

[0017] 2. The upper support plate of the device of the present application is scientifically designed in size. The front and rear width is adapted to the length of an adult's foot, and the left and right width is in line with the width of an adult's shoulders. It is lower than the upper plane of the fixed frame formed by the surrounding front and rear pedals and left and right pedals, forming a natural jumping area and activity space. When the user stands on one foot and causes the upper support plate to press down more, this design can prevent the body from being unbalanced, and the other foot can be quickly placed on the fixed frame to avoid falling, effectively improving the stability and safety of the movement.

[0018] 3. The light strips of the dance machine of the present application are combined with the rhythm of music or the amplitude of dancing, and the controller has multiple built-in dance modes, which users can freely choose through the mobile phone APP. During the dance process, the light strips will display the corresponding content in real time according to the rhythm of music and the amplitude of dancing movements, such as dynamic melody spectrum, etc., bringing users a double feast of vision and hearing, making the dance process more interesting, fully releasing physical and mental emotions, and significantly improving the entertainment and interactivity of the device.

Specific embodiments

[0024] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0025] Referring to Figures 1-3 , an electromagnetic spring type dancing machine, comprising a housing 1, an opening 10 is provided at the top of the housing 1, a support plate 2 is arranged in the opening 10, at least three linear bearings 3 are provided on the bottom wall of the housing 1, a guiding column 31 is arranged at the top of the linear bearing 3 in a liftable manner, the guiding column 31 lifts within the limit range of the linear bearing 3, the top of the guiding column 31 is connected to the support plate 2, preferably four linear bearings 3 are provided on the bottom wall of the housing 1, and the four guiding columns 31 are connected to the four corners of the support plate 2. Through the cooperation of the guiding column 31 and the linear bearing 3, the support plate 2 is prevented from tilting forward, backward, left and right, ensuring that the upper support plate 2 can only move up and down. A tension and compression spring 32 for elastically abutting against the support plate 2 is sleeved outside the linear bearing 3, and the elastic force of the tension and compression spring 32 recovering from deformation urges the support plate 2 to rise to the maximum height.

[0026] Continue to refer to Figures 1-3, 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 above-mentioned support plate 2, a fixing frame 12 is arranged at the bottom of the shell 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 pole of the magnetic field is opposite to that of the permanent magnet core 23, the magnetic field generates an upward thrust by the mutual repulsion of the same magnetic poles, reacting to the downward gravity when a person stands on the support plate 2, when a person stands on the tempered glass 22 and generates a downward pressure on the upper support plate 2, a part of the upward reaction force is borne by the tension and compression spring 32. The laser displacement sensor 4 is connected to the bottom wall of the shell 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 cooperate to enable the dance machine to offset the compression or stretching effect of users of different weights on the spring, so that the spring always remains within a fixed amplitude range.

[0027] Reference Figure 2 , Figure 3 The fixing frame 12 is provided with a guide hole aligned with the permanent magnet core 23. When the lower end of the 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 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 a plurality of light troughs 20, preferably ten light troughs 20 are provided on the support plate 2, light strips 21 are placed in the light troughs 20, and the light strips 21 are used to display music rhythm amplitude patterns. The top surface of the support plate 2 is stacked with tempered glass 22, and the tempered glass 22 is used for people to stand on it and dance.

[0029] The surface of the tempered glass 22 is covered with a light-transmissive anti-skid coating (not shown in the figure), which prevents people from slipping on the tempered glass 22 and ensures 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 instructions to the light strip 21 to synchronize the rhythm of the concert to light up and darken.

[0030] Reference Figure 3 A switch power supply 122 is disposed on the side wall of the fixing frame 12 . When in use, the switch power supply 122 can be turned on or off through the through hole on the wall of the shell 1 .

[0031] The front-to-back width of the above-mentioned support plate 2 is 35 cm, which is in line with the foot length of an adult. The left-to-right width of the support plate 2 is 60 cm, which is in line with the shoulder width of a growing person, and it is lower than the pedal 11, forming a natural jumping area and activity space.

[0032] Refer to Figure 3 、 Figure 4 As described above, the controller 5 is provided with a jack 51 for connecting other dance machines in series. Dance machines can be connected in series by docking the jack 51 with a data cable and put together to form a large stage, bringing a better experience to users.

[0033] Refer to Figure 1 As described above, the upper end of the housing 1 is provided with a pedal 11 extending outward. When imbalance occurs, the other foot of a person can be quickly placed on the fixing frame 12 to prevent falling from the tempered glass 22 plate, playing a safety protection role.

[0034] Refer to Figure 2 As described above, the laser displacement sensor 4 is connected with a bracket 41. The bracket 41 is connected to the bottom wall of the housing 1 by screws. The laser displacement sensor 4 is detachably arranged, which is convenient for later maintenance.

[0035] Refer to Figure 3 As described above, adjusting nuts 13 are provided at the four corners of the bottom of the housing 1. 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 it is easier for a person to find balance when standing on the dance machine.

[0036] Refer to Figures 1-3 As described above, for the above-mentioned dance machine, when a person stands on the support plate 2, the laser displacement sensor 4 detects the sinking displacement of the support plate 2 and transmits 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 for the electromagnetic coil 24 to work according to the signal transmitted by the laser displacement sensor 4, converts it into the weight of a person through the controller 5, adjusts the current of the electromagnetic coil 24, generates an upward thrust in the iron core, combines with the upward thrust generated after the spring is compressed, and adjusts the balance point to a suitable position. When a person's foot exerts force downward, an up-and-down shaking effect can be generated, and the amplitude of the shaking is related to the exerted force. The up-and-down movement amplitude of the dance machine is controlled by the tension and compression spring 32. However, since the weight range of a person is between 40 KG and 110 KG and the elastic coefficient of the spring is a fixed value, the movement amplitude of the spring is limited. Through the auxiliary controllable electromagnetic force, the weight difference of individuals is offset, so that the movement amplitude of the spring is at the same comfortable level. The upper plane of the dance machine is equipped with an atmosphere light strip 21. The atmosphere light strip 21 is combined with the dancing amplitude or music melody. The controller 5 is provided with a variety of accompanying dance modes. After the user automatically selects through the mobile phone APP, the light strip 21 displays the corresponding content.

[0037] The above are only specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification of the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
