Description

Technical Field

[0001] The present invention relates to the technical field of music education, and in particular, to an aging-friendly music education interactive device. Background Art

[0002] With the continuous deepening of the aging population, the demand of the elderly group for enriching spiritual and cultural life is increasing day by day. As an activity beneficial to physical and mental health and cultivating sentiment, music education has gradually gained the favor of the elderly. Against this background, the aging-friendly music education interactive device has emerged, aiming to provide the elderly with a convenient and comfortable music learning experience.

[0003] In the music education interactive device, the piano keyboard, as a core component, its cleaning problem is crucial. Traditional music education equipment, especially the piano keyboard for the elderly, has many difficulties in cleaning. On the one hand, the physical function of the elderly declines, and cleaning actions such as bending down and squatting are difficult for them, making it difficult to clean the keyboard comprehensively and deeply. On the other hand, the ordinary keyboard structure design is not conducive to cleaning, the gaps between the keyboards are narrow, and dust and stains are easy to accumulate in them. Conventional cleaning tools (such as brushes, rags, etc.) are difficult to reach. Long-term use not only affects the appearance of the keyboard, but may also lead to a decrease in key sensitivity, even cause failures, and shorten the service life of the device. In addition, in a public music education environment where multiple people use it, if the keyboard after frequent use cannot be cleaned in time and effectively, it is also easy to breed bacteria, posing a potential threat to the health of users. Summary of the Invention

[0004] In order to overcome the above-mentioned drawbacks, the technical problem of the present invention is: to provide an aging-friendly music education interactive device.

[0005] Technical Solution: An aging-friendly music education interactive device includes an interactive device main body, a piano keyboard, a cover plate and a display screen.

A cleaning sponge is fixedly connected to the front side of the bottom of the moving cover. Hinge rods are rotatably connected to both sides of the front lower end of the cover plate, and the lower ends of the hinge rods are respectively rotatably connected to both sides of the moving cover.

[0006] In a preferred embodiment of the present invention, the surface of each key of the piano keyboard is made of silicone material with a comfortable touch, and has fine textures on the surface. At the same time, the inside of the key adopts a metal shrapnel structure.

[0007] In a preferred embodiment of the present invention, it further includes suction cups, air pipes, cylinders, piston rods, moving rods, buffer springs and pressure relief components. Suction cups are symmetrically installed on both sides of the bottom of the main body of the interaction device. The upper ends of the suction cups on the same side are connected to each other through a through pipe and are in communication. Among them, the front suction cups are respectively connected and communicated with air pipes. Cylinders are symmetrically connected to the inner bottom of the main body of the interaction device. The air pipes are respectively connected and communicated with the cylinders on the same side. Piston rods are slidably connected inside the cylinders. Moving rods are slidably connected to the rear ends of the piston rods. Buffer springs are connected between the moving rods and the inside of the piston rods. The rear ends of the moving rods are respectively slidably connected to the guide rods on the same side and are connected to the moving covers. Pressure relief components are provided on the cylinders.

[0008] In a preferred embodiment of the present invention, the suction cup is a circular rubber material structure, and an elastic rubber flap is provided inside it.

[0009] In a preferred embodiment of the present invention, the pressure relief component includes a sealing rod and a return spring. A notch is opened at the front end of the cylinder. The sealing rod is slidably connected at the notch. A return spring is connected between the sealing rod and the cylinder. In the initial state, the sealing rod blocks the notch.

[0010] In a preferred embodiment of the present invention, it further includes a bidirectional screw, sliders, a motor, a slide rail, a limiting rod and a folding lifting frame. The lower side inside the cover plate is rotatably connected with a bidirectional screw through a bearing. The two sides of the bidirectional screw are respectively threadedly connected with sliders. Slide rails are symmetrically connected to the lower side inside the cover plate. The sliders slide on the corresponding slide rails respectively. The motor is installed at the lower end of the right side wall of the cover plate. The output shaft of the motor is connected to the right end of the bidirectional screw. The upper side of the rear side wall of the display screen is connected with a limiting rod. A folding lifting frame is installed between the two sliders. The folding end at the uppermost end of the folding lifting frame is slidably connected with the limiting rod.

[0011] In a preferred embodiment of the present invention, the folding lifting frame is composed of multiple cross-connected metal rods. The metal rods are made of aluminum alloy material, and all connection points of the folding lifting frame are connected through pin shafts.

[0012] In a preferred embodiment of the present invention, it further includes a metal sheet and a magnetic rubber plate. The front side of the upper part of the display screen is connected with a metal sheet. The magnetic rubber plate is connected at the position close to the metal sheet on the top of the display screen. The two are magnetically matched.

[0013] Compared with the prior art, the present invention has the following advantages: 1. During the process of opening or closing the cover plate, the hinge rod drives the movable cover to move horizontally. This design enables the cleaning sponge fixed on the movable cover to effectively clean the dust, stains and other impurities on the surface and in the gaps of the piano keyboard. Such an automatic cleaning mechanism not only ensures the cleanliness of the keyboard but also provides a good environment for subsequent use.

[0014] 2. When the cover plate is opened, the movable cover drives the piston rod to move, pumping the air between the suction cup and the desktop into the cylinder body, so that the suction cup adsorbs the desktop to achieve automatic fixation; on the contrary, when the cover plate is closed, the piston rod pushes the air in the cylinder body back under the suction cup and releases the negative pressure between the suction cup and the desktop through the pressure relief component, which facilitates the user to easily pick up and move the entire device.

[0015] 3. The motor drives the bidirectional screw to rotate, causing the slider to move along the slide rail, thereby controlling the folding lifting frame to expand or contract, driving the display screen to accurately adjust the height, meeting the needs of the elderly of different heights and diverse usage scenarios.

Detailed implementation manners

[0030] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as "above", "below", "upward", "downward", etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0031] Example 1: An aging-friendly music education interactive device, as Figures 1 - 6As shown in the figure, it includes an interactive device main body 1, a piano keyboard 101, a cover plate 102, a display screen 103, a hinge rod 201, a guide rod 202, a moving cover 203, a partition 204, and a cleaning sponge 205. The interactive device main body 1 serves as the basic load-bearing structure of the entire device. The rear side of its top is rotatably connected to the cover plate 102 through a rotating shaft to achieve the function of the cover plate 102 opening and closing like a flip cover. The piano keyboard 101 is precisely assembled at the groove part on the front side of the top of the interactive device main body 1. The display screen 103 is slidably connected to the cover plate 102, jointly constituting the front-end operation and display part of the entire interactive device. The surface of each key of the piano keyboard 101 is made of silicone material with a comfortable touch, and the surface has fine textures to increase the friction between the finger and the key and prevent slipping during playing. And the inside of the key adopts a metal elastic sheet structure to ensure the sensitivity and reliability of key triggering. Guide rods 202 are symmetrically welded on the left and right sides inside the interactive device main body 1. A moving cover 203 is slidably connected between the two guide rods 202. The position of the moving cover 203 is set behind the piano keyboard 101. Multiple partitions 204 are connected to its front side at intervals. The widths of these partitions 204 are carefully designed to be precisely adapted to the spacing between each key on the piano keyboard 101. A cleaning sponge 205 is detachably connected to the front side of the bottom of the moving cover 203. This cleaning sponge 205 undertakes the important task of cleaning the piano keyboard 101 during the operation of the device. Hinge rods 201 are rotatably connected to the left and right sides of the front side of the lower end of the cover plate 102. The lower ends of the hinge rods 201 are respectively rotatably connected to both sides of the moving cover 203.

[0032] When performing music education interactive operations, first, the user needs to connect the main body 1 of the interactive device to the power supply to complete the power supply preparation. Subsequently, manually rotate the cover plate 102 upward to open it. At this time, the user can perform debugging operations on the display screen 103, use the functions of the display screen 103 to select suitable sheet music and melodies. After selecting the teaching content, the user follows the sheet music prompts and learns music interactively by pressing the piano keys 101. During this process, the inclination angle of the display screen 103 can be adjusted according to the actual needs of the user by adjusting the opening and closing angle of the cover plate 102, so as to meet the viewing needs in different usage scenarios. When the use is over, perform the device storage operation and rotate the cover plate 102 downward to close it. During the process of rotating the cover plate 102 downward, the hinge rod 201 on the front side of the lower end of the cover plate 102 will rotate accordingly. Since the lower end of the hinge rod 201 is rotatably connected to both sides of the moving cover 203, the rotation of the cover plate 102 will push the moving cover 203 to move forward along the guide rod 202 through the hinge rod 201. During the forward movement of the moving cover 203, the partition plate 204 connected to its front side and the cleaning sponge 205 connected to the bottom will move forward synchronously. The moving cover 203 will finally cover the piano keys 101. During this process, the cleaning sponge 205 will perform a cleaning and wiping action on the surface of the piano keys 101, effectively removing dust and stains on the keyboard surface. And the partition plate 204 will move forward along the gaps between the piano keys 101. On the one hand, it can block external dust from entering the keyboard gaps, and on the other hand, it can push out the impurities originally existing in the gaps forward, realizing the cleaning and protection of the gaps of the piano keys 101. In this way, during the process of closing the cover plate 102, the automatic wiping and cleaning function of the piano keys 101 is realized. Similarly, when opening the cover plate 102, the rotation of the cover plate 102 will also push the moving cover 203 to move backward and open through the hinge rod 201. During this process, the cleaning sponge 205 and the partition plate 204 will pass through the piano keys 101 again, realizing another cleaning action, so as to ensure that the piano keys 101 are always in a clean state and provide good conditions for subsequent use.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 3 , Figure 4 and Figures 7 - 10As shown in the figure, it also includes a suction cup 301, an air tube 302, a cylinder body 303, a piston rod 304, a moving rod 305, a buffer spring 306 and a pressure relief component. Suction cups 301 are symmetrically installed in the front and back on both the left and right sides of the bottom of the main body 1 of the interaction device. The upper ends of the suction cups 301 on the same side are connected to each other through a through pipe and are in communication. Among them, the front suction cups 301 are respectively connected and in communication with an air tube 302. The left and right sides of the inner bottom of the main body 1 of the interaction device are symmetrically connected by screws with cylinder bodies 303. The air tubes 302 are respectively connected and in communication with the cylinder bodies 303 on the same side. Piston rods 304 are slidably connected in the cylinder bodies 303. The rear ends of the piston rods 304 are slidably connected with moving rods 305. Buffer springs 306 are connected between the moving rods 305 and the interiors of the piston rods 304. The rear ends of the moving rods 305 are respectively slidably connected with the guiding rods 202 on the same side and are connected to the moving cover 203, so as to achieve synchronous movement. The suction cup 301 is a circular rubber structure, and an elastic rubber flap is provided inside it, which can form a good sealing effect when contacting the tabletop, ensuring that the suction cup 301 can effectively maintain a negative pressure state when adsorbing the tabletop. A pressure relief component is provided on the cylinder body 303.

[0034] As Figures 8 - 9 shown in the figure, the pressure relief component includes a sealing rod 401 and a return spring 402. A notch is opened at the front end of the cylinder body 303. A sealing rod 401 is slidably connected at the notch. A return spring 402 is connected between the sealing rod 401 and the cylinder body 303. In the initial state, the sealing rod 401 blocks the notch. When the piston rod 304 moves forward and contacts the sealing rod 401, it will push the sealing rod 401 to move forward, thereby releasing the blockage of the notch, enabling the interior of the cylinder body 303 to communicate with the outside world and achieving the purpose of pressure relief.

[0035] When using this device, place it on the desktop. When the cover plate 102 is opened, the cover plate 102 drives the movable cover 203 to move backward along the guide rod 202 through the hinge rod 201, and this action further drives the movable rod 305 and the piston rod 304 to move backward together. When the cover plate 102 is in the closed state, the piston rod 304 abuts against the sealing rod 401. At this time, the notch is in the open state, and the return spring 402 is in the stretched state. When the piston rod 304 moves backward and disengages from the abutment with the sealing rod 401, under the reset action of the return spring 402, the sealing rod 401 moves backward, thereby closing the notch. As the piston rod 304 moves backward, the air between the suction cup 301 and the desktop will be pumped into the cylinder body 303 through the air pipe 302, so that a negative pressure state is formed between the suction cup 301 and the desktop, thereby enabling the suction cup 301 to firmly adsorb on the desktop. As the movable cover 203 continues to move backward, when the piston rod 304 cannot continue to move backward under the action of air pressure, the movable rod 305 will continue to move because it is connected to the movable cover 203. At this time, the buffer spring 306 will be compressed to adapt to this change and effectively avoid jamming, thereby realizing the automatic fixation between the interactive device and the desktop. When the device is used up, close the cover plate 102. The cover plate 102 pushes the movable cover 203 to move forward through the hinge rod 201. The movable cover 203 drives the movable rod 305 and the piston rod 304 to move forward, and the buffer spring 306 is compressed accordingly. During this process, the piston rod 304 pushes the air in the cylinder body 303 back into the suction cup 301. At the same time, when the piston rod 304 abuts against the sealing rod 401, it will push the sealing rod 401 to move forward, so that it disengages from the closure of the notch, and the return spring 402 is further stretched. The inside of the cylinder body 303 will communicate with the outside air. At this time, the negative pressure state between the suction cup 301 and the desktop is eliminated, enabling the interactive device to be normally picked up and moved, realizing automatic pressure relief.

[0036] As Figures 11 - 13As shown in the figure, it further includes a bidirectional screw 501, sliders 502, a motor 503, slide rails 504, a limiting rod 505, and a folding lifting frame 506. The lower side inside the cover plate 102 is rotatably connected to the bidirectional screw 501 through a bearing. The left and right sides of the bidirectional screw 501 are respectively threadedly connected to the sliders 502. The left and right sides of the lower side inside the cover plate 102 are symmetrically welded with slide rails 504. The sliders 502 slide on the corresponding slide rails 504 respectively, thereby ensuring the stability of the movement of the sliders 502. The lower end of the right side wall of the cover plate 102 is installed with a motor 503 through bolts. The output shaft of the motor 503 is tightly connected to the right end of the bidirectional screw 501 through a coupling. The upper side of the rear side wall of the display screen 103 is connected to the limiting rod 505. A folding lifting frame 506 is installed between the two sliders 502. The uppermost folding end of the folding lifting frame 506 is slidably connected to the limiting rod 505. The folding lifting frame 506 is composed of multiple cross-connected metal rods. The metal rods are made of aluminum alloy material, which has the characteristics of light weight and high strength. Each connection point of the folding lifting frame 506 is connected through a pin shaft, enabling the folding lifting frame 506 to be flexibly unfolded and retracted. When the folding lifting frame 506 rises or falls, it will drive the display screen 103 to rise or fall synchronously through the limiting rod 505, thereby realizing the precise adjustment of the height of the display screen 103.

[0037] During the actual use process, if it is necessary to adjust the height of the display screen 103, the user can start the motor 503. The rotation of the output shaft of the motor 503 drives the bidirectional screw 501 to rotate synchronously. Due to the special thread structure of the bidirectional screw 501, when it rotates, it will drive the sliders 502 on the left and right sides to move closer to or away from each other along the slide rails 504. When the sliders 502 move closer to each other, it will drive the folding lifting frame 506 to unfold upward, and then push the display screen 103 to move upward along the cover plate 102 through the limiting rod 505, realizing the height increase; on the contrary, control the motor 503 to rotate in the reverse direction, the bidirectional screw 501 will rotate in the reverse direction, driving the two sliders 502 to move away from each other, causing the folding lifting frame 506 to descend and contract, and then driving the limiting rod 505 and the display screen 103 to move downward, reducing the height of the display screen 103. After adjusting to the appropriate height, turn off the motor 503, and the entire adjustment process is completed, meeting the precise adjustment requirements for the height of the display screen 103 for the elderly of different heights and diverse usage scenarios.

[0038] Such as Figures 1 - 2As shown in the figure, it further includes a metal sheet 104 and a magnetic rubber sheet 105. The metal sheet 104 is connected to the front side of the upper part of the display screen 103, and the magnetic rubber sheet 105 is connected to the position of the display screen 103 near the metal sheet 104 at the top. When a paper music score needs to be used, the elderly can lay the music score flat on the surface of the display screen 103 to make it closely fit with the metal sheet 104. Subsequently, fold the magnetic rubber sheet 105 downward, and utilize the magnetic attraction between the magnetic rubber sheet 105 and the metal sheet 104 to achieve firm fixation of the paper music score, avoiding displacement or dropping of the music score during use. When the music score needs to be removed, just open the magnetic rubber sheet 105 outward to release its magnetic adsorption with the metal sheet 104, and then the music score can be easily removed. The operation is simple and convenient, fully considering the convenience of the elderly during use.

[0039] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
