Description

Technical Field

[0001] This utility model relates to the technical field of metronomes, and in particular to a convenient electronic metronome. Background Technology

[0002] An electronic metronome is an electronic device used to provide accurate and stable rhythm. In music teaching, it helps students better understand and master changes in rhythm, tempo, and time signature by providing stable rhythmic support, thereby improving the accuracy and coordination of their playing. Electronic metronomes not only help students develop a sense of rhythm but also allow them to precisely control tempo during practice, gradually improving their playing skills.

[0003] Currently available electronic metronomes include a housing with a display, speaker, buttons, control module, and stand. The stand supports the metronome in an upright position and is U-shaped with both ends hinged to the housing. In use, the stand is rotated along the hinges, forming an acute angle with the housing, and then placed on a table for support. For details, please refer to the electronic metronome disclosed in patent publication number JP5855837B2.

[0004] In music teaching, a metronome is typically placed on the podium and turned up to maximum volume so students can hear it clearly. However, existing support structures are unstable. When the metronome produces sound, it vibrates, which is transmitted to the podium surface, causing noise and displacement. This noise is particularly noticeable on metal multimedia teaching desktops. Furthermore, teachers usually stand on the podium to teach or play instruments to the side, making it inconvenient for them to view and operate the metronome. In conclusion, existing support structures are inconvenient for teaching use. Utility Model Content

[0005] To address the issues of poor support stability and inconvenience in teaching with electronic metronomes, this invention provides an electronic metronome that offers high support stability and is easy to carry and use.

[0006] This utility model provides a convenient electronic metronome, which adopts the following technical solution: A portable electronic metronome includes a metronome body, a stretchable clamping assembly, and a foldable support mechanism. The clamping assembly is used to clamp other objects and is disposed on the metronome body. The support mechanism includes a drive base, a support block slidably disposed on the drive base, a drive assembly for synchronously driving the support block to slide closer to or further away from each other, a rotation assembly for adjusting the direction of the metronome body, and a folding assembly for adjusting the height of the metronome body; at least two support blocks are provided, and the support blocks slide and engage with the drive base in a direction that moves closer to or further away from each other; the drive assembly and the rotation assembly are both disposed on the drive base; one end of the folding assembly is connected to the rotation assembly, and the other end is connected to the clamping assembly; anti-slip vibration damping components are also provided on the support blocks.

[0007] By adopting the above technical solution, during use, depending on the surrounding environment, users can choose to use the support blocks for stable support on a flat surface, or choose to use the drive component to synchronously drive the support blocks to slide closer or further apart, clamping or releasing the support blocks at any point. Then, the direction of the metronome body can be adjusted by rotating the component, and the height of the metronome body can be adjusted by folding the component, adapting to the usage needs of the metronome body in different scenarios. The metronome body provides the beat, and the clamping component holds a mobile phone or other objects, allowing users to simultaneously view sheet music or perform other functions on their mobile phones while using the metronome body, facilitating singing, playing, and viewing music, thus making it convenient for teaching. After use, by resetting the support blocks, folding component, and clamping component, the entire unit can be stored in a block shape for easy transport to different classrooms or scenarios.

[0008] Preferably, the clamping assembly includes a clamping seat connected to the metronome body, a movable rod slidably disposed on the clamping seat, and a pad connected to the movable rod; the clamping seat has a sliding groove and an inlet / outlet communicating with the outside of the clamping seat, the cross-sectional area of ​​the inlet / outlet being smaller than the cross-sectional area of ​​the sliding groove; the movable rod includes a sliding part and a mounting part, the sliding part slidingly engaging with the inlet / outlet, each of the sliding parts being provided with a slider, the slider slidingly engaging with the sliding groove; the movable rod is fitted with an elastic element, the two ends of the elastic element abutting against the slider and the wall of the sliding groove, respectively.

[0009] By adopting the above technical solution, in its natural state, the elastic element 1 causes both the slider and the sliding part to extend into the groove, that is, the movable rod is retracted; when clamping an object, by gripping the pad, the movable rod is driven to slide, at which time the elastic element 1 is compressed, placing the object between the pad and the carrying plate. When the pad is released, the elastic force of the elastic element 1 causes the pad and the carrying plate to clamp the object, thus enabling the use of the metronome body while simultaneously using a mobile phone to view sheet music and other functions, facilitating singing, playing, and viewing.

[0010] Preferably, the metronome body is provided with a support plate, and the pad and the support plate are distributed facing each other.

[0011] By adopting the above technical solution, placing the mobile phone or object between the pad and the carrier plate helps to make the mobile phone or object more stable when clamping it.

[0012] Preferably, the support block includes a sliding part and a supporting part, the sliding part is slidably engaged with the drive seat, and the sliding part does not fall off the drive seat.

[0013] By adopting the above technical solution, the sliding effect between the sliding part and the drive seat is ensured, and the sliding part is prevented from falling off.

[0014] Preferably, the drive assembly includes a transmission disk rotatably disposed within a drive seat and an adjusting rod for driving the transmission disk to rotate; one side of the transmission disk is provided with a thread facing the support block, and the sliding part cooperates with the thread; the adjusting rod passes through the drive seat, and a transmission wheel is provided at one end of the adjusting rod extending into the drive seat; a first locking tooth is provided on the side of the transmission disk opposite to the thread, and a second locking tooth is provided on the transmission wheel that meshes with the first locking tooth; a handwheel is provided at the end of the adjusting rod located outside the drive seat.

[0015] By adopting the above technical solution, when clamping the support, the drive handwheel rotates, causing the adjusting rod to drive the transmission wheel to rotate. Through the meshing of the first and second locking teeth, the transmission disc rotates, causing the support blocks to slide in directions that bring them closer or further apart. This allows for flexible adjustment of the distance between the two support blocks, clamping or releasing them at any point. The operation is convenient and the support is stable. The synchronous sliding of the support blocks saves driving time and quickly achieves clamping or releasing. Compared with the traditional bolt adjustment method, it saves equipment space, is easy to carry, and allows users to adjust the position of the support blocks according to actual needs to obtain the most suitable support effect, making it suitable for different classrooms or other usage scenarios.

[0016] Preferably, a portion of the anti-slip vibration isolation components are located on the side of the support portion away from the sliding portion, while another portion of the anti-slip vibration isolation components are located on the side of the support portion facing each other.

[0017] By adopting the above technical solution, the anti-slip vibration isolation component plays an anti-slip and vibration isolation role during support and clamping, thereby preventing the transmission of the metronome body vibration and thus preventing noise or displacement.

[0018] Preferably, the anti-slip vibration isolation component is a rubber pad as described in the prior art.

[0019] By adopting the above technical solutions, the rubber pads have good wear resistance, aging resistance and weather resistance, and the rubber pads also have high cost-effectiveness and can maintain their performance in long-term use.

[0020] Preferably, the rotating assembly includes a locking seat disposed on the drive seat, a gear ring disposed on the locking seat, a drive chassis rotatably connected to the locking seat, and a locking block that slides and engages with the drive chassis along the radial direction of the gear ring; an elastic element two is also disposed between the locking block and the drive chassis, and the end of the locking block facing the gear ring is a telescopic drive part.

[0021] By adopting the above technical solution, when the drive chassis is rotated, one inclined surface of the telescopic drive unit moves relative to one inclined surface of the retaining ring, causing the retaining block to slide and the elastic element two to compress. When the drive chassis stops rotating, the elastic force of the elastic element two causes the telescopic drive unit to extend between the two teeth of the toothed ring, thereby achieving locking. This facilitates adjustment of the metronome body's direction and ensures stability after rotation, preventing shaking and adapting to the usage needs of different scenarios.

[0022] Preferably, the drive chassis is provided with a base plate, the base plate is provided with a rotating shaft, the rotating shaft extends into the drive seat and is rotatably connected to the drive seat.

[0023] By adopting the above technical solution, the shaft prevents the base plate from detaching from the drive chassis and falling onto the drive seat.

[0024] Preferably, the folding assembly includes a first connecting rod hinged to the base plate and a second connecting rod hinged to the first connecting rod; the second connecting rod is hinged to the clamp.

[0025] By adopting the above technical solution, the folding components can be unfolded or retracted by driving the first and second connecting rods to rotate, thereby adjusting the height of the metronome body.

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. Depending on the surrounding environment, the support blocks can be used to provide stable support on a flat surface, or the support blocks can be driven synchronously by the drive assembly to slide closer or further apart, clamping or releasing the support blocks at any point. This adapts to different usage environments and ensures stable support. At the same time, the anti-slip vibration isolation components play a role in preventing slipping and vibration, thereby preventing the transmission of vibration of the metronome body and thus preventing noise or displacement. 2. By opening or resetting the drive support block, folding component and clamping component, the metronome body is more flexible to use and easier to store, making it easier to carry to different classrooms or scenarios. 3. When clamping an object, by gripping the pad, the moving rod is driven to slide. At this time, the elastic element is compressed, placing the object between the pad and the carrying plate. When the pad is released, the elastic force of the elastic element clamps the object between the pad and the carrying plate. This allows the user to use the metronome while simultaneously using a mobile phone to view sheet music and other functions, making it convenient for singing, playing, and viewing music.

[0035] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] A portable electronic metronome, as described above Figure 1 The system includes a metronome body 1, a stretchable clamping component 2, and a foldable support mechanism. The metronome body 1 is used to implement the beat function, the clamping component 2 is used to clamp other objects, and the support mechanism is used to store and support the metronome body 1 and the clamping component 2. The metronome body 1 is rectangular in shape, with one side serving as the display / operation side. The metronome body 1 is a conventional technology and will not be described in detail. In this embodiment, the clamping component 2 is used to clamp a mobile phone. The clamping component 2 is mounted on the metronome body 1 and faces away from the display / operation side. The support mechanism is connected to the clamping component 2.

[0037] Specifically, refer to Figure 1 and Figure 2 The clamping assembly 2 includes a clamping base 21, a movable rod 22 slidably disposed on the clamping base 21, and a pad 23 connected to the movable rod 22.

[0038] Reference Figure 1 and Figure 2 The clamp 21 is rectangular in shape and is distributed along the length of the metronome body 1. The clamp 21 is fixed to the metronome body 1 by bolts and faces away from the display / operation side. A groove 8 with a circular cross-section is provided inside the clamp 21, distributed along the width of the clamp 21. An inlet / outlet 9 is provided on one side of the clamp 21 to connect the groove 8 to the outside of the clamp 21. The inlet / outlet 9 is distributed along the width of the clamp 21, also with a circular cross-section, and connects to the groove 8. The cross-sectional area of ​​the inlet / outlet 9 is smaller than that of the groove 8. Two grooves 8 are provided, evenly spaced along the length of the clamp 21. Two inlets / outlets are provided corresponding to the number of grooves 8, and each inlet / outlet 9 connects to one of the two grooves 8.

[0039] Reference Figure 1 and Figure 2 The movable rod 22 is U-shaped and includes two parallel sliding portions 221 and a mounting portion 222 connecting the two sliding portions 221. The sliding portions 221 are adapted to the inlet / outlet 9, meaning the sliding portions 221 slide and engage with the inlet / outlet 9, with each of the two sliding portions 221 corresponding to one of the two inlet / outlet 9, allowing the sliding portions 221 to extend into or extend out of the inlet / outlet 9. Each sliding portion 221 is provided with a slider 24, located at the end of the sliding portion 221 away from the mounting portion 222. The slider 24 extends into and slides into the groove 8, meaning there are two sliders 24, each corresponding to one of the two grooves 8. This limits the sliding distance of the movable rod 22, preventing it from detaching from the clamp 21. The arrangement of the two sliding portions 221 and the two sliders 24 helps to make the sliding of the movable rod 22 more stable.

[0040] Reference Figure 2 and Figure 3 The pad 23 is fitted and fixedly connected to the mounting part 222 of the movable rod 22. By gripping the pad 23, the sliding part 221 is driven to slide along the length direction of the inlet / outlet 9, while the slider 24 slides along the length direction of the groove 8, thus easily driving the movable rod 22 to slide. A carrying plate 26 is also provided on one side of the metronome body 1, with the pad 23 and the carrying plate 26 facing each other. In addition, each sliding part 221 is fitted with an elastic element 25, which is a spring. One end of the elastic element 25 abuts against the slider 24, and the end of the elastic element 25 away from the slider 24 abuts against the wall of the groove 8. In its natural state, the elastic element 25 causes both the slider 24 and the sliding part 221 to extend into the groove 8, that is, the movable rod 22 is retracted. When holding a mobile phone (or object), the movable rod 22 is driven to slide by gripping the pad 23. At this time, the elastic element 25 is compressed, placing the mobile phone (or object) between the pad 23 and the carrier plate 26. When the pad 23 is released, the elastic force of the elastic element 25 causes the pad 23 and the carrier plate 26 to clamp the mobile phone (or object), so that while using the metronome body 1, other functions such as viewing sheet music can be used simultaneously, making it convenient for singing, playing, and viewing.

[0041] In use, the metronome body 1 and clamping assembly 2 are supported by the unfolded support mechanism. The metronome body 1 provides the beat. By gripping the pad 23, the movable rod 22 is driven to slide, and the mobile phone or object is placed between the pad 23 and the carrying plate 26. The pad 23 is released, and the elastic force of the elastic element 25 clamps the mobile phone between the pad 23 and the carrying plate 26, making it convenient to use and suitable for teaching environments.

[0042] Specifically, refer to Figure 1 and Figure 4 The support mechanism includes a drive base 3, a support block 4 slidably disposed on the drive base 3, a drive component 5 disposed on the drive base 3, a rotating component 6 disposed on the drive base 3, and a folding component 7 connected between the rotating components 6. The rotating component 6 is used to adjust the direction of the metronome body 1, and the folding component 7 is used to adjust the height of the metronome body 1. One end of the folding component 7 is connected to the rotating component 6, and the other end is connected to the clamping component 2.

[0043] Reference Figure 3 and Figure 4The drive seat 3 is rectangular in shape. A long groove 11 is formed on the drive seat 3, with an inverted T-shaped cross-section. The long groove 11 is distributed along the direction in which the two support blocks 4 face each other. The support block 4 includes a sliding part 41 and a support part 42. The sliding part 41 is adapted to the shape of the long groove 11, and the sliding part 41 slides and engages with the long groove 11 of the drive seat 3. The support part 42 is rectangular in shape and abuts against the outer surface of the drive seat 3, allowing the support block 4 to slide and engage with the drive seat 3 along the length of the long groove 11. Based on the shapes of the long groove 11 and the sliding part 41, the sliding part 41 does not detach from the drive seat 3. At least two support blocks 4 are provided. The two support blocks 4 slide and cooperate with the drive seat 3 in a direction that is close to or far from each other. In this embodiment, two support blocks 4 are provided. The two support blocks 4 are distributed in a mirror image. The long groove 11 is provided with two corresponding support blocks 4. The sliding part 41 of the two support blocks 4 slides and cooperates with the two long grooves 11 one by one.

[0044] Reference Figure 4 and Figure 5 The drive assembly 5 is used to synchronously drive the support blocks 4 to slide closer to or further away from each other. Specifically, the drive assembly 5 includes a transmission disk 51 rotatably disposed within the drive base 3 and an adjusting rod 52 for driving the transmission disk 51 to rotate.

[0045] Reference Figure 4 and Figure 5 The drive block has a transmission cavity 12, which communicates with the elongated groove 11. The transmission disc 51 is disc-shaped and located inside the transmission cavity 12, with one side of the transmission disc 51 facing the support block 4. The side of the transmission disc 51 facing the support block 4 is provided with threads, and the sliding part 41 on the side facing the transmission disc 51 cooperates with the threads on the transmission disc 51. When the drive transmission disc 51 is rotated, both sliding parts 41 follow the rotation of the threads, causing the two support blocks 4 to slide in a direction that moves closer or further apart from each other.

[0046] Reference Figure 4 and Figure 5 The transmission disc 51 has a first locking tooth on the side opposite to the thread. An adjusting rod 52 passes through the drive seat 3, with one end extending into the transmission cavity 12 inside the drive seat 3 and the other end outside the drive seat 3, away from the support block 4. A transmission wheel 53 is located at the end of the adjusting rod 52 extending into the transmission cavity 12. The transmission wheel 53 has a second locking tooth that meshes with the first locking tooth, meaning the transmission wheel 53 meshes with the transmission disc 51. A handwheel 54 is located at the end of the adjusting rod 52 outside the drive seat 3, allowing for easy gripping and rotation of the adjusting rod 52.

[0047] In use, the two support blocks 4 provide stable support on a flat surface, or can be driven to clamp any object for support. When clamping, rotating the drive handwheel 54 causes the adjusting rod 52 to rotate the transmission wheel 53. The meshing of the first and second locking teeth rotates the transmission disc 51, causing the two support blocks 4 to slide closer or further apart. This allows for flexible adjustment of the distance between the two support blocks 4, clamping or releasing them at any point. The operation is convenient and the support is stable. The synchronous sliding of the two support blocks 4 saves driving time and quickly achieves clamping or releasing. Compared to traditional bolt adjustment methods, it saves space and is easy to carry. Users can adjust the position of the support blocks 4 according to actual needs to obtain the most suitable support effect, adapting to different classrooms or other usage scenarios.

[0048] In addition, refer to Figure 4 and Figure 5 The support block 4 is also equipped with anti-slip vibration isolation components 10. Multiple anti-slip vibration isolation components 10 are provided and fixedly connected to the support portion 42. Some anti-slip vibration isolation components 10 are located on the side of the support portion 42 away from the sliding portion 41, while other anti-slip vibration isolation components 10 are located on the side of the two support portions 42 facing each other. The anti-slip vibration isolation components 10 are existing rubber pads, which can be attached to the support block 4 using commercially available rubber pads. Rubber pads have good wear resistance, aging resistance, and weather resistance, and are also cost-effective, maintaining their performance over long-term use. During support and clamping, they play an anti-slip and vibration isolation role, thereby preventing the transmission of vibration of the metronome body 1, and thus preventing noise or displacement.

[0049] In use, stable support is provided by supporting or clamping the support block 4, and the vibration transmission of the metronome body 1 is prevented by the anti-slip vibration isolation component 10, thereby preventing noise or displacement. The direction of the metronome body 1 is adjusted by driving the rotation component 6, and the height of the metronome body 1 is adjusted by the folding component 7, so as to facilitate the operation and viewing of the metronome body 1 when standing in the classroom or playing musical instruments.

[0050] Specifically, refer to Figure 3 and Figure 4 The rotating assembly 6 includes a locking seat 61 disposed on the drive base 3, a toothed ring 62 disposed on the locking seat 61, a drive chassis 63 rotatably connected to the locking seat 61, and a locking block 64 slidably disposed on the drive chassis 63.

[0051] Reference Figure 3 and Figure 4The locking seat 61 is circular and is fixedly connected to the drive base 3 by bolts. The gear ring 62 and the locking seat 61 are on the same central axis. The locking seat 61 is rotatably connected to the drive chassis 63, allowing the drive chassis 63 to rotate smoothly on the locking seat 61. The drive chassis 63 has a through hole 13, which is circular and extends through the drive chassis 63. The gear ring 62 extends into the through hole 13, and the through hole 13 and the gear ring 62 are also on the same central axis. Figure 6 The locking block 64 slides and engages with the drive chassis 63 along the radial direction of the toothed ring 62. One end of the locking block 64 facing the toothed ring 62 is a telescopic drive part 641, which is triangular in shape. An elastic element 65, also a spring, is provided between the locking block 64 and the drive chassis 63. The elastic element 65 is distributed along the sliding direction of the locking block 64, with one end connected to the locking block 64 and the other end connected to the drive chassis 63.

[0052] Reference Figure 3 and Figure 6 When the drive chassis 63 is rotated, one inclined surface of the telescopic drive part 641 moves relative to one inclined surface of the retaining ring, causing the retaining block 64 to slide and the elastic element 65 to compress. When the drive chassis 63 stops rotating, the elastic force of the elastic element 65 causes the telescopic drive part 641 to extend between two teeth of the toothed ring 62, thereby achieving locking. This facilitates adjustment of the direction of the metronome body 1, ensures stability after rotation, prevents shaking, and can adapt to the usage needs of different scenarios.

[0053] In addition, refer to Figure 3 and Figure 4 The drive chassis 63 is also provided with a base plate 66, which is connected to the drive chassis 63 by bolts. A rotating shaft 67 is also provided on the base plate 66, which extends into the drive seat 3 and is rotatably connected to the drive seat 3. Thus, rotating the base plate 66 or the drive chassis 63 can adjust the direction of the metronome body 1, and the rotating shaft 67 prevents the base plate 66 from falling off the drive chassis 63 to the drive seat 3.

[0054] In use, stable support is provided by supporting or clamping the support block 4, and the transmission of vibration of the metronome body 1 is prevented by the anti-slip vibration damping component 10. The direction of the metronome body 1 can be adjusted by rotating the base plate 66 or driving the chassis 63. The height of the metronome body 1 can be adjusted by unfolding or folding the folding component 7, so as to facilitate the operation and viewing of the metronome body 1 when standing in the classroom or playing musical instruments.

[0055] Specifically, refer to Figure 1 and Figure 4The folding assembly 7 includes a first connecting rod 71 hinged to the base plate 66 and a second connecting rod 72 hinged to the first connecting rod 71. The first connecting rod 71 is a long rod, with one end hinged to the base plate 66 and the other end hinged to the end of the second connecting rod 72. There are two first connecting rods 71, both hinged to the base plate 66. The second connecting rod 72 is also a long rod, located between the two first connecting rods 71. One end of the second connecting rod 72 is hinged to both first connecting rods 71, and the other end is hinged to the clamp 21. Thus, by driving the first connecting rod 71 and the second connecting rod 72 to rotate, the folding assembly 7 can be unfolded or folded up to adjust the height of the metronome body 1.

[0056] The implementation principle of this application is as follows:

[0057] In use, depending on the surrounding environment, you can choose to use the two support blocks 4 for stable support on a plane, or you can choose to drive the handwheel 54 to rotate, so that the adjusting rod 52 drives the transmission wheel 53 to rotate. Through the meshing of the first and second locking teeth, the transmission disc 51 is driven to rotate, so that the two support blocks 4 slide in a direction that is closer or farther away from each other, and clamp or release the two support blocks 4 at any point.

[0058] Next, the direction of the metronome body 1 can be adjusted by rotating the base plate 66 or the drive chassis 63, and the stability after rotation is ensured. By rotating the drive linkage 1 71 and the drive linkage 2 72, the folding component 7 can be unfolded or folded up to adjust the height of the metronome body 1, thereby facilitating the adjustment of the direction and height of the metronome body 1 and adapting to the usage needs of different scenarios.

[0059] The metronome body 1 then provides the beat, and the anti-slip vibration damping member 10 prevents the transmission of vibration of the metronome body 1, thereby preventing noise or displacement. By gripping the pad 23, the movable rod 22 is driven to slide, placing the mobile phone or object between the pad 23 and the carrying plate 26. The pad 23 is released, and the elastic force of the elastic member 25 clamps the mobile phone between the pad 23 and the carrying plate 26. This allows the mobile phone to be used simultaneously to view sheet music and other functions while using the metronome body 1, facilitating singing, playing, and viewing, and thus making it convenient for teaching.

[0060] After use, the support block 4, folding component 7 and clamping component are reset to make the whole block shape for easy carrying to different classrooms or scenarios.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
