Description

Technical Field

[0001] The utility model relates to the technical field of display devices, and particularly relates to a display device for the design of the brachistochrone structure. Background Technique

[0002] The display device for the design of the brachistochrone structure is used to display and compare the movement process of an object along the brachistochrone with the movement process along a straight line. Its basic principle is to set a cycloid track and a straight track with the same starting height and the same ending height. Let two balls with the same mass and size start to fall freely along the straight track and the cycloid track respectively from the stationary state. Although the cycloid track is longer than the straight track, because the cycloid track is the brachistochrone, the ball falling along the cycloid track has a faster speed and a shorter time used, and the ball rolling on the cycloid track reaches the end first.

[0003] After retrieval, Chinese Patent Publication No. CN203070614U discloses a brachistochrone demonstrator, which includes a high platform and slideways. Four slideways with different curvatures are fixed on the right edge of the high platform. There are two card slots at the two right corners of the high platform, and baffles are clamped in the card slots; four short slideways are fixed on the high platform, and the lower ends of the four short slideways lean against the baffles; each of the lower ends of the four slideways is provided with a sensor, and each sensor is connected to a light bulb. The utility model has a simple structure and is convenient to use. By observing the order of the light bulbs being lit when the balls slide down from the four slideways with different curvatures, it can be identified which slideway the ball slides down fastest, proving the existence of the brachistochrone, enabling students to more clearly understand this principle and increasing students' interest in learning physical knowledge.

[0004] Although the above patent can prove the existence of the brachistochrone, the release of the balls is greatly affected by human factors, it is difficult to ensure that multiple balls are released simultaneously in a stationary state, and it is very difficult to ensure the accuracy of the proof result, resulting in an unclear display effect. Therefore, it is necessary to design a display device for the design of the brachistochrone structure to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a display device for the design of the brachistochrone structure, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A device for demonstrating the design of a brachistochrone structure, including a display stand. On one side of the upper surface of the display stand, a high platform is fixedly connected. On the other side of the upper surface of the display stand, a base is fixedly connected. A track is movably connected to the upper surface of the display stand. At the top of the outer surface of the high platform, an electromagnet is fixedly connected. A placement groove is opened on the outer surface of the electromagnet. A laser timer is fixedly connected to the outer surface of the base, and a display screen is fixedly connected to the upper surface of the base.

[0011] To achieve the effect of facilitating batch display, as a device for demonstrating the design of a brachistochrone structure of the present utility model, the number of the tracks is several, and several tracks are evenly installed on the upper surface of the display stand in a horizontal array form.

[0012] To achieve the effect of facilitating buffering, as a device for demonstrating the design of a brachistochrone structure of the present utility model, a second spring is fixedly connected to the inner side surface of the base.

[0025] Embodiment

[0026] As Figures 1-5 shown, a device for demonstrating the brachistochrone structure design includes a display table 1. On one side of the upper surface of the display table 1, a high platform 2 is fixedly connected. On the other side of the upper surface of the display table 1, a base 3 is fixedly connected. A track 4 is movably connected to the upper surface of the display table 1; at the top of the outer surface of the high platform 2, an electromagnet 5 is fixedly connected. A placement groove 6 is formed on the outer surface of the electromagnet 5. A laser timer 7 is fixedly connected to the outer surface of the base 3, and a display screen 8 is fixedly connected to the upper surface of the base 3.

[0027] During specific use, through the settings of the track 4, the electromagnet 5, the laser timer 7, and the display screen 8, multiple tracks 4 are installed between the high platform 2 and the base 3. The starting heights of the multiple tracks 4 are the same, and the ending heights are also the same, only the curvatures are different. The surface of the electromagnet 5 is provided with a placement groove 6, and the bottom of the placement groove 6 is an arc-shaped inclined structure. A small ball is placed into the interior of the placement groove 6 and fixed and released by the electromagnet 5, effectively reducing the time error caused by manual release, effectively improving the accuracy and efficiency of the display. Multiple small balls simultaneously fall freely along the track 4 from a stationary state. When the small ball falls to the end point, it blocks the laser of the laser timer 7, and the resistance value of the photoresistor increases rapidly. When it exceeds the given resistance value, the end time is recorded and displayed on the display screen 8 for easy viewing by personnel. The use is convenient, further improving the interactivity of the device, enabling the audience to intuitively understand the relevant knowledge of the brachistochrone, realizing a dynamic display, and improving the display effect.

[0028] In this embodiment, on one side of the front surface of the high platform 2, a control button 9 is fixedly connected. On the front surface of the high platform 2, close to the control button 9, a reset button 10 is fixedly connected.

[0029] During specific use, through the settings of the control button 9 and the reset button 10, the control button 9 is convenient for operating and controlling the electromagnet 5, and the reset button 10 can reset and clear the time displayed on the display screen 8 for convenient reuse.

[0030] In this embodiment, a clamping strip 11 is fixedly connected to the lower surface of the track 4, and a clamping groove 12 is formed on the upper surface of the display table 1 close to the clamping strip 11.

[0031] During specific use, through the settings of the clamping strip 11 and the clamping groove 12, the clamping strip 11 is clamped inside the clamping groove 12, facilitating the clamping and fixing of the track 4 and preventing left - right movement.

[0032] In this embodiment, a first spring 13 is fixedly connected to the middle of the outer surface of the high platform 2. One end of the first spring 13 is fixedly connected to a limiting post 14, and a limiting hole 15 is formed on the outer surface of the track 4 near the limiting post 14.

[0033] During specific use, through the settings of the limiting post 14 and the limiting hole 15, the limiting post 14 is pressed so that it and the first spring 13 are received inside the high platform 2, facilitating the installation of the track 4 between the high platform 2 and the base 3. When the bottom of the track 4 contacts the display platform 1, under the elastic action of the first spring 13, the limiting post 14 is clamped inside the corresponding limiting hole 15, limiting and fixing the track 4 to prevent up - down shaking, ensuring the firmness of the installation and the stability of use. The limiting post 14 and the limiting hole 15 are of arc structure. Under the action of an external force, the limiting post 14 can be retracted into the high platform 2, making the installation and disassembly of the track 4 more convenient.

[0034] In this embodiment, the number of tracks 4 is several, and several tracks 4 are evenly installed on the upper surface of the display platform 1 in a horizontal array form.

[0035] During specific use, through the setting of the track 4, there are multiple tracks 4, and tracks 4 with different arcs can be designed, facilitating the deceleration movement of multiple small balls simultaneously for easy observation.

[0036] In this embodiment, a second spring 16 is fixedly connected to the inner side surface of the base 3, and one end of the second spring 16 is fixedly connected to a buffer plate 17.

[0037] During specific use, through the setting of the buffer plate 17, the buffer plate 17 is arranged above the ball - falling hole 18 through the second spring 16. When the small ball falls and contacts the buffer plate 17, under the mutual cooperation of the second spring 16 and the buffer plate 17, the force of the small ball after entering the base 3 is buffered, preventing damage to the base 3, strengthening the buffer effect. At the same time, under the action of the force, the buffer plate 17 moves, thus opening the ball - falling hole 18, facilitating the small ball to accurately fall into the ball - falling hole 18, increasing the quickness and stability of the small ball's fall.

[0038] In this embodiment, ball - falling holes 18 are formed on both the inner bottom wall of the base 3 and the upper surface of the display platform 1, and a guiding groove 19 is formed at the top of the inner side surface of the display platform 1.

[0039] During specific use, due to the setting of the ball dropping hole 18, the ball dropping hole 18 facilitates the falling of the small balls into the interior of the base 3. The falling small balls move towards the storage tray 21 through the inclined guide groove 19, thus achieving automatic storage and increasing the convenience of use.

[0040] In this embodiment, support plates 20 are fixedly connected to both sides of the front surface of the display stand 1, and a storage tray 21 is fixedly connected to the interior of the support plates 20.

[0041] During specific use, due to the setting of the storage tray 21, the support plates 20 support and fix the storage tray 21 to ensure the firmness of use. The storage tray 21 is used to receive the falling small balls, facilitating the user to pick them up.

[0042] Working principle: During use, the clamping strip 11 is clamped inside the clamping groove 12. Under the elastic action of the first spring 13, the limiting post 14 is clamped inside the corresponding limiting hole 15 to limit and fix the track 4. Multiple tracks 4 are provided and can be designed with different arcs to facilitate the deceleration movement of multiple small balls simultaneously. The small balls are placed inside the placement groove 6, and the control button 9 is used to operate the electromagnet 5. The electromagnet 5 fixes and releases the small balls to reduce the time error caused by manual release. Multiple small balls simultaneously fall freely along the track 4 from the stationary state. When the small balls reach the end point, they block the laser of the laser timer 7, record the end time, and display it on the display screen 8, enabling the audience to intuitively understand the relevant knowledge of the brachistochrone, realizing dynamic display. Under the mutual cooperation of the second spring 16 and the buffer plate 17, the force of the small balls after entering the base 3 is buffered to avoid damage to the base 3. When the buffer plate 17 moves under the action of the force, the ball dropping hole 18 is opened, facilitating the small balls to accurately fall into the interior of the ball dropping hole 18. The guide groove 19 enables the small balls to move towards the storage tray 21, thus achieving automatic storage and facilitating the user to pick them up.
