Description

Technical Field

[0001] This utility model relates to the field of musical instrument technology, and in particular to a folding assembly and a musical instrument. Background Technology

[0002] The musical instrument comprises a first part and a second part. In related technologies, the first and second parts have two different connection methods: one is a fixed installation, where the first and second parts are an integrated structure; the other is a semi-detachable installation structure, where the first and second parts can be disassembled. However, fixed-installation instruments occupy a large volume and are difficult to store. Semi-detachable instruments have a cumbersome disassembly process, making them extremely inconvenient for users to carry and transport. Therefore, how to design a space-saving and portable musical instrument is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0044] The musical instrument according to this embodiment of the invention includes a first part, a second part, and a folding assembly. The folding assembly is used to fold the first part and the second part. The musical instrument can be an electronic keyboard, a guitar, or other foldable musical instruments. For ease of description, the musical instrument will be described as a guitar below. The first part is the body of the guitar. The second part is the neck of the guitar.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The guitar 100 of this embodiment includes a body 10, a neck 20, and a folding assembly 30. The folding assembly 30 includes a first rotating assembly 31, a second rotating assembly 32, and a third rotating assembly 33. The first rotating assembly 31 includes a first fixing member 310 and a first rotating member 311. The first fixing member 310 is fixedly connected to the body 10, and the first rotating member 311 is configured to rotate under the drive of the first fixing member 310. The second rotating assembly 32 includes a second fixing member 320 and a second rotating member 321. The second fixing member 320 is fixedly connected to the neck 20, and the second rotating member 321 is configured to rotate under the drive of the second fixing member 320. The rotation direction of the first rotating member 311 is opposite to the rotation direction of the second rotating member 321. The third rotating assembly 33 is rotatably connected to both the first rotating assembly 31 and the second rotating assembly 32. During the folding process of the body 10 and the neck 20, the first rotating member 311 and the second rotating member 321 are configured to rotate relative to the third rotating assembly 33.

[0046] In the guitar 100 of this embodiment, the neck 20 can be folded relative to the body 10 through the coordinated action of the first rotating component 31, the second rotating component 32, and the third rotating component 33, thereby significantly reducing the overall size of the guitar 100 and making it convenient to carry and transport. Furthermore, the opposite rotational directions of the first and second rotating components 31 and 32, and their rotational connection with the third rotating component 33, ensure smoother movement of the body 10 and neck 20 during folding and unfolding, avoiding segmented folding and thus improving the user experience.

[0047] Specifically, the body 10 can be the main part of the guitar 100 for sound production and structural support. The body 10 can serve as a fixed base and is connected to the folding assembly 30 via the first rotating assembly 31. The body 10 can be made of wood, composite materials, or other suitable materials.

[0048] The neck 20 is the main playing part of the guitar 100. The neck 20 is connected to the folding assembly 30 via the second rotating assembly 32, allowing the neck 20 to fold relative to the body 10. The neck 20 can be made of wood, composite materials, or other suitable materials.

[0049] The folding assembly 30 is used to fold the body 10 and neck 20. The folding assembly 30 achieves the folding and unfolding of the body 10 and neck 20 through the coordinated action of three rotating components. For example, using the folding assembly 30, the guitar 100 can be folded from... Figure 1 Folding to the unfolded state Figure 6 The folded state can also be seen from Figure 6 The folded state unfolds to Figure 1 The unfolded state. In the first rotating assembly 31, the first rotating element 311 can be a gear, connecting rod, or other rotating device. The first fixing element 310 can be fixedly connected to the body 10 by means of bolts, welding, etc.

[0050] In the second rotating assembly 32, the second rotating element 321 can be a gear, a connecting rod, or other rotating device. The second fixed element 320 can be fixedly connected to the neck 20 by means of bolts, welding, or other methods.

[0051] The third rotating assembly 33 serves as the central connection point, allowing the first and second rotating members 321 to rotate relative to the third rotating assembly 33 during folding. The third rotating assembly 33 may be a bearing, hinge, gear, or other rotating device.

[0052] During the folding process of the body 10 and neck 20, the first rotating component 311 and the second rotating component 321 rotate relative to the third rotating assembly 33. The folding and unfolding of the body 10 and neck 20 are achieved through the opposite rotation of the first and second rotating components 321. During the folding process, the rotation of the first rotating component 311 and the second rotating component 321 can be clockwise or counterclockwise.

[0053] Please refer to Figure 1 and Figure 6 In some embodiments, the body 10 includes a body portion 11 and a recessed portion 12, and at least a portion of the neck 20 is accommodated in the recessed portion 12 after being folded with the body 10.

[0054] This reduces the space occupied by the guitar body when folded, thereby further reducing the space occupied by the guitar 100 and making it easier to carry.

[0055] Specifically, the body portion 11 is the main part of the instrument body 10. The recess 12 is a recessed area on the instrument body 10 for accommodating at least part of the neck 20 when folded. For example, the entire neck 20 is accommodated within the recess 12. The recess 12 can be arc-shaped, rectangular, or other suitable shapes, and its shape can be adapted to the shape of the neck 20.

[0056] Please refer to Figure 5 , Figure 7 and Figure 8 In some embodiments, the first fixing member 310 includes a first connecting part 3100 and a second connecting part 3101, the first rotating member 311 includes a first rotating shaft 3110, the first connecting part 3100 and the second connecting part 3101 are connected at an angle, the first connecting part 3100 is fixedly connected to the body 10, the second connecting part 3101 is sleeved on the first rotating shaft 3110, and the first rotating shaft 3110 is configured to rotate under the drive of the second connecting part 3101;

[0057] The second fixing member 320 includes a third connecting part 3200 and a fourth connecting part 3201. The second rotating member 321 includes a second rotating shaft 3210. The third connecting part 3200 and the fourth connecting part 3201 are connected at an angle. The third connecting part 3200 is fixedly connected to the neck 20. The fourth connecting part 3201 is sleeved on the second rotating shaft 3210. The second rotating shaft 3210 is configured to rotate under the drive of the fourth connecting part 3201.

[0058] Thus, since the first connecting part 3100 and the second connecting part 3101 are connected at an angle, and the third connecting part 3200 and the fourth connecting part 3201 are connected at an angle, the space occupied by the first rotating component 31 and the second rotating component 32 is small. This can reduce the space occupied by the folding component 30, thereby reducing the space occupied by the guitar 100 and making it easier to carry the guitar 100.

[0059] Specifically, the first fastener 310 can be made of metal, plastic, or other suitable materials. The first connecting portion 3100 and the second connecting portion 3101 can be integrally molded, which can improve the structural strength of the first fastener 310 and thus prevent the first fastener 310 from breaking. Alternatively, the first connecting portion 3100 and the second connecting portion 3101 can be separately molded, which allows one of the connecting portions to be replaced individually in the event of partial damage to the first fastener 310, reducing maintenance costs.

[0060] The second fastener 320 can be made of metal, plastic, or other suitable materials. The third connecting part 3200 and the fourth connecting part 3201 can be integrally molded, which can improve the structural strength of the second fastener 320 and thus prevent the second fastener 320 from breaking. Alternatively, the third connecting part 3200 and the fourth connecting part 3201 can be separately molded, which allows one of the connecting parts to be replaced individually in case of partial damage to the second fastener 320, reducing maintenance costs.

[0061] Both the first rotating shaft 3110 and the second rotating shaft 3210 can be straight shafts, crankshafts, or other suitable shaft types.

[0062] Please refer to Figure 5 , Figure 7 and Figure 8 In some embodiments, the first rotating member 311 further includes a first gear 3111, the second rotating member 321 further includes a second gear 3211, the first gear 3111 is sleeved on the first rotating shaft 3110, the second gear 3211 is sleeved on the second rotating shaft 3210, and the third rotating assembly 33 includes a third gear 330, the first side of the third gear 330 meshes with the first gear 3111, and the second side of the third gear 330 meshes with the second gear 3211.

[0063] Thus, through the meshing of gears, the movement of the body 10 and neck 20 folding or unfolding smoothly improves the user experience. Furthermore, the gear transmission method has a longer service life.

[0064] Specifically, the first gear 3111 transmits the rotation of the first rotating shaft 3110 to the third gear 330 through meshing with the third gear 330. The first gear 3111 can be a spur gear, helical gear, or other suitable gear type, and the specific design can be selected according to the transmission requirements.

[0065] The first side and the second side of the third gear 330 are opposite sides of the third gear 330. The second gear 3211 transmits the rotation of the second rotating shaft 3210 to the third gear 330 through meshing with the third gear 330. The second gear 3211 can be a spur gear, helical gear, or other suitable gear type, and the specific design can be selected according to the transmission requirements.

[0066] Please refer to Figure 5 , Figure 7 and Figure 8 In some embodiments, the third gear 330 includes a first sub-gear 3300 and a second sub-gear 3301 that mesh with each other. The first sub-gear 3300 meshes with the first gear 3111, and the second sub-gear 3301 meshes with the second gear 3211.

[0067] Thus, by setting two sub-gears to mesh with the first gear 3111 and the second gear 3211 respectively, the smoothness between the third gear 330 and the first gear 3111, as well as between the third gear 330 and the second gear 3211, can be improved. By dividing the third gear 330 into two sub-gears, the transmission ratio between the first rotating member 311 and the second rotating member 321 can be controlled more precisely, thereby achieving more precise folding and unfolding actions, and making the folding or unfolding process of the body 10 and the neck 20 smoother.

[0068] Specifically, the first sub-gear 3300 and the second sub-gear 3301 can be arranged side by side. Both the first sub-gear 3300 and the second sub-gear 3301 rotate around their own rotation axis.

[0069] During use, the body 10 rotates under drive, causing the first connecting part 3100 to rotate, which in turn causes the second connecting part 3101 to rotate, which in turn causes the first rotating shaft 3110 to rotate, which in turn causes the first gear 3111 to rotate. The first gear 3111 transmits the rotation to the first sub-gear 3300 of the third gear 330. The rotation of the first sub-gear 3300 causes the second sub-gear 3301 to rotate, which in turn drives the second gear 3211.

[0070] When the neck 20 is driven to rotate, it drives the third connecting part 3200 to rotate, which in turn drives the fourth connecting part 3201 to rotate, which in turn drives the second rotating shaft 3210 to rotate, which in turn drives the second gear 3211 to rotate. The second gear 3211 transmits the rotation to the second sub-gear 3301 of the third gear. The rotation of the second sub-gear 3301 drives the first sub-gear 3301 to rotate, which in turn drives the first gear 3111 to rotate. The rotation of the first gear 3111 drives the first rotating shaft 3110 to rotate, which in turn drives the second connecting part 3101 to rotate, which in turn drives the body 10 to rotate.

[0071] In this way, the neck 20 will simultaneously rotate as it is driven to rotate, and the body 10 will simultaneously rotate as it is driven to rotate. Therefore, only one of the body 10 and the neck 20 needs to be folded, without having to fold the body 10 and the neck 20 in sections to ensure a smooth folding process.

[0072] In some embodiments, the central axis of the first gear 3111, the central axis of the first sub-gear 3300, the central axis of the second sub-gear 3301, and the central axis of the second gear 3211 are all parallel.

[0073] Thus, the parallel central axis design makes the structures of the first rotating assembly 31, the second rotating assembly 32, and the third rotating assembly 33 compact, which reduces the space occupied by the folding assembly 30, thereby reducing the space occupied by the guitar 100 and making it easier to carry. Furthermore, the parallel central axis design reduces vibration and noise of the gears during transmission, improving the stability and reliability of the transmission.

[0074] Specifically, the parallelism of the central axis of the first gear 3111, the central axis of the first sub-gear 3300, the central axis of the second sub-gear 3301, and the central axis of the second gear 3211 means that any two of the central axes of the first gear 3111, the first sub-gear 3300, the second sub-gear 3301, and the second gear 3211 are parallel. For example, the central axis of the first gear 3111 and the central axis of the first sub-gear 3300 are parallel.

[0075] The central axis of the first gear 3111 can be the axis of rotation of the first gear 3111. The central axis of the first sub-gear 3300 can be the axis of rotation of the first sub-gear 3300. The central axis of the second sub-gear 3301 can be the axis of rotation of the second sub-gear 3301. The central axis of the second gear 3211 can be the axis of rotation of the second gear 3211.

[0076] Please refer to Figure 5 , Figure 7 and Figure 8In some embodiments, the first rotating member 311 further includes a first rotating cam 3112 sleeved on the first rotating shaft 3110, and the folding assembly 30 further includes a concave wheel plate 34 sleeved on the first rotating shaft 3110 and the second rotating shaft 3210. The first rotating cam 3112 includes a first main body portion 3113 and a first protrusion portion 3114 protruding from one side of the first main body portion 3113. The concave wheel plate 34 includes a second main body portion 340 and a first recessed portion 341 connected to the second main body portion 340. The first protrusion portion 3114 is configured to cooperate with the second main body portion 340 or the first recessed portion 341 during rotation.

[0077] The second rotating member 321 also includes a second rotating cam 3212 sleeved on the second rotating shaft 3210. The second rotating cam 3212 includes a third main body 3213 and a second protrusion 3214 protruding from one side of the third main body 3213. The concave wheel plate 34 also includes a second recess 342 connected to the second main body 340. The second protrusion 3214 is configured to cooperate with the third main body 3213 or the second recess 342 during rotation.

[0078] Thus, through the cooperation of the first protrusion 3114 with the second main body 340 or the first recess 341, the torque required for the rotation of the first rotating shaft 3110 can be provided, thereby reducing the force required to drive the first rotating assembly 31 to rotate; through the cooperation of the second protrusion 3214 with the third main body 3213 or the second recess 342, the torque required for the rotation of the first rotating shaft 3110 can be provided, thereby reducing the force required to drive the second rotating assembly 32 to rotate.

[0079] Specifically, the first protrusion 3114 can be circular, rectangular, or other suitable shapes. The first protrusion 3114 can move between the second main body 340 and the first recess 341. During the movement of the first protrusion 3114, the torque required for the rotation of the first rotating shaft 3110 can be provided.

[0080] The second protrusion 3214 can be circular, rectangular, or other suitable shapes. The second protrusion 3214 can move between the third main body 3213 and the second recess 342. During the movement of the second protrusion 3214, the torque required for the rotation of the second rotating shaft 3210 can be provided.

[0081] Please refer to Figure 5 , Figure 7 and Figure 8In some embodiments, the first rotating assembly 31 further includes a first elastic element 312, which is disposed on the side of the first rotating cam 3112 away from the concave wheel plate 34. The first elastic element 312 is configured to be in a compressed position when the first protrusion 3114 rotates to engage with the second main body 340, and is configured to be in a relaxed position when the first protrusion 3114 rotates to engage with the first recess 341.

[0082] The second rotating assembly 32 also includes a second elastic element 322, which is disposed on the side of the second rotating cam 3212 away from the concave wheel plate 34. The second elastic element 322 is configured to be in a compressed position when the second protrusion 3214 rotates to engage with the third main body 3213, and is configured to be in a relaxed position when the second protrusion 3214 rotates to engage with the second recess 342.

[0083] Thus, through the arrangement of the first elastic element 312 and the second elastic element 322, the first protrusion 3114 and the second protrusion 3214 can generate damping during rotation, thereby providing a damped feel to the guitar 100 during folding or unfolding. Furthermore, the compression and relaxation of the first elastic element 312 and the second elastic element 322 provide additional stability and a self-locking function, ensuring that the guitar 100 folds and unfolds more smoothly and reliably.

[0084] Specifically, the first elastic element 312 can be a spring, an elastic washer, or other suitable structure. For example, the first elastic element 312 can be four elastic washers arranged in a linear fashion, thereby providing a large elastic force in the axial direction of the first rotation axis 3110 to meet the damping and self-locking requirements of the guitar 100 during folding or unfolding.

[0085] The second elastic element 322 can also be a spring, an elastic washer, or other suitable structure. For example, the second elastic element 322 can be four elastic washers arranged in a linear fashion, thereby providing a large elastic force in the axial direction of the first rotation axis 3110 to meet the damping and self-locking requirements of the guitar 100 during folding or unfolding.

[0086] Please refer to Figure 7 and Figure 8In some embodiments, the folding assembly 30 further includes a first nut 36 threadedly connected to the first rotating shaft 3110, and a first friction plate 37 abutting against the two adjacent sides of the first nut 36 and the first elastic member 312. Thus, the first nut 36 can restrict the movement of components such as the first elastic member 312, the first rotating cam 3112, and the concave wheel plate 34, thereby maintaining the stability of the folding assembly 30 during the folding process. The first friction plate 37 can reduce the frictional force on the first nut 36 and the first elastic member 312, thereby improving the service life of the first nut 36 and the first elastic member 312.

[0087] Please refer to Figure 7 and Figure 8 In some embodiments, the folding assembly 30 further includes a second nut 38 threadedly connected to the second rotating shaft 3210, and a second friction plate 39 abutting against the two adjacent sides of the second nut 38 and the second elastic member 322. Thus, the second nut 38 can restrict the movement of components such as the second elastic member 322, the second rotating cam 3212, and the concave wheel plate 34, thereby maintaining the stability of the folding assembly 30 during the folding process. The second friction plate 39 can reduce the frictional force on the second nut 38 and the second elastic member 322, thereby improving the service life of the second nut 38 and the second elastic member 322.

[0088] Please refer to Figure 7 and Figure 8 In some embodiments, the folding assembly 30 further includes a gear seat 35, which is connected to both the first gear 3111 and the second gear 3211, and a concave wheel plate 34 is connected to both the first gear 3111 and the second gear 3211. The gear seat 35 and the concave wheel plate 34 are located on opposite sides of the first gear 3111.

[0089] In this way, the gear seat 35 can work together with the concave plate 34 to support the first gear 3111 and the second gear 3211 on both sides, thereby fixing the first gear 3111 and the second gear 3211 so that the first gear 3111 and the second gear 3211 can run smoothly.

[0090] Specifically, the gear housing 35 can be made of metal, plastic, or other suitable materials. The gear housing 35 provides stable support, ensuring that the first gear 3111 and the second gear 3211 remain stable during rotation.

[0091] The concave plate 34 can be made of metal, plastic, or other suitable materials. The concave plate 34 provides additional support and stability by connecting with the first gear 3111 and the second gear 3211.

[0092] Please refer to Figure 7 , Figure 8 and Figure 9In some embodiments, the folding assembly 30 further includes a fixing base 101, a connector 102, a fourth rotating assembly 103, and a fifth rotating assembly 104. The fixing base 101 and the gear seat 35 are connected by the connector 102. The fourth rotating assembly 103 includes a third fixing member 1030 and a third rotating member 1031.

The first rotating member 311, the second rotating member 321, the third rotating member 1031, and the fourth rotating member 1041 are all mounted on the fixing base 101.

[0093] Thus, by setting the connector 102, the first rotating component 31, the second rotating component 32, the third rotating component 33, the fourth rotating component 103 and the fifth rotating component 104 can be integrated on the same fixed base 101. This makes the structure of the folding component 30 compact, thereby improving the space utilization of the guitar 100 and reducing the use of additional installation parts, thus reducing the weight of the guitar 100 and making it easier to carry.

[0094] Specifically, the fixing base 101 provides stable support, ensuring that the various parts of the folding assembly 30 remain stable during rotation. The first rotating member 311, the second rotating member 321, the third rotating member 1031, and the fourth rotating member 1041 can all be accommodated within the fixing base 101. The fixing base 101 can rotate with the first rotating member 311, the second rotating member 321, the third rotating member 1031, and the fourth rotating member 1041.

[0095] The connector 102 is used to connect the fixed base 101 and the gear seat 35. The connector 102 can be a bolt, screw, pin, or other suitable connecting device. For example, the connector 102 can be a bolt, and the fixed base 101 and the gear seat 35 have corresponding threaded holes. The connector 102 can pass through the threaded holes on the fixed base 101 and the gear seat 35 to connect the fixed base 101 and the gear seat 35.

[0098] Please refer to Figure 7 and Figure 9 In some embodiments, the third rotating member 1031 includes a third rotating shaft 1032 and a third rotating cam 1033. The third rotating shaft 1032 is connected to the fixed seat 101, and the third rotating cam 1033 is sleeved on the third rotating shaft 1032. The third fixed member 1030 includes a fourth main body 1034 and a third recessed portion 1035 connected to the fourth main body 1034. The third rotating cam 1033 includes a fifth main body 1036 and a third protruding portion 1037 protruding from one side of the fifth main body 1036. The third protruding portion 1037 is configured to cooperate with the fourth main body 1034 or the third recessed portion 1035 during rotation.

[0099] The fourth rotating member 1041 includes a fourth rotating shaft 1042 and a fourth rotating cam 1043. The fourth rotating shaft 1042 is connected to the fixed seat 101.

The fourth protruding portion 1047 is configured to cooperate with the sixth main body 1044 or the fourth recessed portion 1045 during rotation.

[0100] Thus, the cooperation between the third protrusion 1037 and the fifth main body 1036 or the third recess 1035 can provide the torque required during rotation, thereby reducing the force required to drive the fourth rotating assembly 103 to rotate; the cooperation between the fourth protrusion 1047 and the sixth main body 1044 or the fourth recess 1045 can provide the torque required during rotation, thereby reducing the force required to drive the fifth rotating assembly 104 to rotate.

[0101] Specifically, the third protrusion 1037 can be circular, rectangular, or other suitable shapes. The third protrusion 1037 can move between the fourth main body 1034 and the third recess 1035. During the movement of the third protrusion 1037, the torque required for the rotation of the third rotating shaft 1032 can be provided.

[0102] The sixth main body portion 1044 may be the main outline shape portion of the fourth fastener 1040. The sixth main body portion 1044 and the fourth recessed portion 1045 may share the same surface. The fourth recessed portion 1045 may be recessed into one side of the sixth main body portion 1044.

[0103] The seventh main body 1046 may be the main outline shape of the fourth rotating cam 1043. The seventh main body 1046 and the fourth protrusion 1047 may share the same surface.

[0104] The fourth protrusion 1047 can be circular, rectangular, or other suitable shapes. The fourth protrusion 1047 can move between the sixth main body 1044 and the fourth recess 1045. During the movement of the fourth protrusion 1047, the torque required for the rotation of the fourth rotating shaft 1042 can be provided.

[0105] Please refer to Figure 7 and Figure 9 In some embodiments, the fourth rotating assembly 103 further includes a third elastic member 1038, which is disposed on the side of the third rotating cam 1033 opposite to the third recess 1035. The third elastic member 1038 is configured to be in a compressed position when the third protrusion 1037 rotates to engage with the fourth main body 1034, and is configured to be in a relaxed position when the third protrusion 1037 rotates to engage with the third recess 1035.

[0106] The fifth rotating assembly 104 also includes a fourth elastic member 1048, which is disposed on the side of the fourth rotating cam 1043 opposite to the fourth recess 1045. The fourth elastic member 1048 is configured to be in a compressed position when the fourth protrusion 1047 rotates to engage with the sixth main body 1044, and is configured to be in a relaxed position when the fourth protrusion 1047 rotates to engage with the fourth recess 1045.

[0107] Thus, through the arrangement of the third elastic element 1038 and the fourth elastic element 1048, the third protrusion 1037 and the fourth protrusion 1047 can generate damping during rotation, thereby providing a damped feel to the guitar 100 during folding. Furthermore, the compression and relaxation of the third elastic element 1038 and the fourth elastic element 1048 provide additional stability and a self-locking function, ensuring that the guitar 100 folds and unfolds more smoothly and reliably.

[0108] Specifically, the third elastic element 1038 can be a spring, an elastic washer, or other suitable structure. For example, the third elastic element 1038 can be four elastic washers arranged in a linear fashion, thereby providing a large elastic force in the axial direction of the third rotation axis 1032 to meet the damping and self-locking requirements of the guitar 100 during folding or unfolding.

[0109] The fourth elastic element 1048 can also be a spring, an elastic washer, or other suitable structure. For example, the fourth elastic element 1048 can be four elastic washers arranged in a linear fashion, thereby providing a large elastic force in the axial direction of the fourth rotation axis 1042 to meet the damping and self-locking requirements of the guitar 100 during folding or unfolding.

[0110] Please refer to Figure 7 and Figure 9 In some embodiments, the third rotating shaft 1032 includes a first rod 105 and a first support portion 106 connected to the first rod 105. A third fixing member 1030 is sleeved on the first rod 105. The folding assembly 30 includes a third friction plate 107, which abuts against the adjacent sides of the first support portion 106 and the third fixing member 1030. Thus, the first support portion 106 can restrict the movement of components such as the third elastic member 1038, the third rotating cam 1033, and the third fixing member 1030 along the axial direction of the third rotating shaft 1032, thereby maintaining the stability of the folding assembly 30 during the folding process. The third friction plate 107 can reduce the frictional force on the first support portion 106 and the third fixing member 1030, thereby increasing the service life of the first support portion 106 and the third fixing member 1030.

[0111] Please refer to Figure 7 and Figure 9 In some embodiments, the folding assembly 30 further includes a third nut 108 threadedly connected to the third rotation shaft 1032, and a fourth friction plate 109 abutting against the two adjacent sides of the third nut 108 and the third elastic member 1038. Thus, the third nut 108 can restrict the movement of components such as the third elastic member 1038, the third rotating cam 1033, and the third fixing member 1030 along the axial direction of the third rotation shaft 1032, thereby maintaining the stability of the folding assembly 30 during the folding process. The fourth friction plate 109 can reduce the frictional force on the third nut 108 and the third elastic member 1038, thereby improving the service life of the third nut 108 and the third elastic member 1038.

[0112] Please refer to Figure 7 and Figure 9 In some embodiments, the fourth rotating shaft 1042 includes a second rod 1001 and a second support portion 1002 connected to the second rod 1001. A fourth fixing member 1040 is sleeved on the second rod 1001. The folding assembly 30 includes a fifth friction plate 1003, which abuts against the adjacent sides of the second support portion 1002 and the fourth fixing member 1040. Thus, the second support portion 1002 can restrict the movement of components such as the fourth elastic member 1048, the fourth rotating cam 1043, and the fourth fixing member 1040 along the axial direction of the fourth rotating shaft 1042, thereby maintaining the stability of the folding assembly 30 during the folding process. The fifth friction plate 1003 can reduce the frictional force on the second support portion 1002 and the fourth fixing member 1040, thereby increasing the service life of the second support portion 1002 and the fourth fixing member 1040.

[0113] Please refer to Figure 7 and Figure 9In some embodiments, the folding assembly 30 further includes a fourth nut 1004 threadedly connected to the fourth rotation shaft 1042, and a sixth friction plate 1005 abutting against the adjacent sides of the fourth nut 1004 and the fourth elastic member 1048. Thus, the fourth nut 1004 can restrict the axial movement of components such as the fourth elastic member 1048, the fourth rotation cam 1043, and the fourth fixing member 1040 along the fourth rotation shaft 1042, thereby maintaining the stability of the folding assembly 30 during the folding process. The sixth friction plate 1005 can reduce the frictional force on the fourth nut 1004 and the fourth elastic member 1048, thereby improving the service life of the fourth nut 1004 and the fourth elastic member 1048.

[0114] Please refer to Figure 7 In some embodiments, the third rotating shaft 1032 is provided with a first through hole 1006, the fourth rotating shaft 1042 is provided with a second through hole 1007, and the guitar 100 also includes a cable 1008, which passes through the first through hole 1006 and the second through hole 1007.

[0115] Thus, the placement of the first through hole 1006 and the second through hole 1007 facilitates the passage of the cable 1008, thereby improving the arrangement of the cable 1008 and increasing the space utilization of the guitar 100.

[0116] Specifically, the first via 1006 allows the cable 1008 to pass through the third rotating shaft 1032, enabling the orderly arrangement of the cable 1008. The first via 1006 can be circular, rectangular, or other suitable shapes. The second via 1007 allows the cable 1008 to pass through the fourth rotating shaft 1042, also enabling the orderly arrangement of the cable 1008. The second via 1007 can be circular, rectangular, or other suitable shapes. The cable 1008 is used to transmit signals to enable the function of the guitar 100.

[0117] Please refer to Figure 7 and Figure 8 In some embodiments, connector 102 includes a first sub-connector 1020 and a second sub-connector 1021, which are located on opposite sides of cable 1008.

[0118] In this way, the cable 1008 is less likely to rub against the first sub-connector 1020 and the second sub-connector 1021, which can improve the service life of the cable 1008.

[0119] Specifically, the first sub-connector 1020 can be a bolt, screw, pin, or other suitable connecting device. The second sub-connector 1021 can be a bolt, screw, pin, or other suitable connecting device.

[0120] Please refer to Figure 7 In some embodiments, the fourth rotating assembly 103 and the fifth rotating assembly 104 are symmetrically arranged about the centerline of the third rotating assembly 33.

[0121] Thus, through symmetrical arrangement, the rotation process of the fourth rotating component 103 and the fifth rotating component 104 is smooth, which can improve the stability of the folding process of the body 10 and the neck 20.

[0122] Specifically, the fourth rotating component 103 may have the same structure as the fifth rotating component 104.

[0123] The centerline is the axis of symmetry of the third rotating component 33. It should be noted that... Figure 7 The dashed line in the diagram shows the center line of the third rotating component 33, but this is only a schematic diagram for ease of understanding and should not be taken as a limitation on the embodiments of this utility model.

[0124] Please refer to Figure 7 In some embodiments, the first rotating component 31 and the second rotating component 32 are symmetrically arranged about the centerline of the third rotating component 33.

[0125] Thus, through symmetrical arrangement, the rotation process of the first rotating component 31 and the second rotating component 32 is smooth, which can improve the stability of the folding process of the body 10 and the neck 20.

[0126] Specifically, the first rotating component 31 can have the same structure as the second rotating component 32.

[0127] Please refer to Figure 1 and Figure 6 In some embodiments, the guitar 100 also includes a frame 40, and a hinge mechanism 50 is provided on the body 10. The first end 41 of the frame 40 is rotatably connected to the body 10, and the second end 42 of the frame 40 is connected to the body 10 through the hinge mechanism 50. The inner surface 43 of the frame 40 is configured to fit against the outer surface of the body 10 after rotating at a preset angle.

[0128] In this way, the frame 40 can rotate through the hinge mechanism 50 and fit against the outer surface of the body 10, which enables the frame 40 to be stored in the body 10, thereby reducing the space occupied by the guitar 100 after folding, so as to facilitate the carrying of the guitar 100.

[0129] Specifically, the hinge mechanism 50 can be a regular hinge or a bearing hinge, etc. For example, a hinge can be installed at the corresponding position of the second end 42 of the frame 40 and the body 10, and the axis of the hinge is parallel to the rotation axis of the first end 41 of the frame 40, so as to ensure that the frame 40 remains stable when rotating.

[0130] The rotatable connection between the first end 41 of the frame 40 and the body 10 can be achieved by means of a pivot or hinge. The inner surface 43 of the frame 40 can be adapted to the shape of the outer surface of the body 10.
