Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nail stepping, specifically relating to a nail stepping device and an encoder control system. Background Technology
[0002] In the field of electronic musical instruments and effects pedal control, the pedal pedal is a core human-computer interaction component for performers to switch sound effects and adjust parameters. Its functional integration and operational reliability directly affect the live performance effect. Traditional instrument pedals mostly adopt a single mechanical switch structure, which can only realize the basic on / off signal triggering function. However, modern music performances have increasingly higher demands for the precision of sound effect control. Performers often need to perform compound operations of parameter adjustment (such as effects pedal reverb intensity, delay time, etc.) and timbre switching at the same time. This makes it difficult for traditional single-function pedals to meet the actual use needs.
[0003] In existing technologies, some solutions employ a parallel layout of multiple foot pedals to expand their functionality. While this enables various control functions, its large size and complex operating logic can easily lead to accidental activation during stage performances. Other improved solutions attempt to integrate rotational encoding functions into a single foot pedal. Although this allows for adjustment of rotational parameters, the complex mechanical structure results in decreased control accuracy due to gear wear, and prolonged use can cause the transmission mechanism to jam.

[0007] The outer wall of the reset tube has a stepped shaft structure. The outer wall of the large shaft is slidably set in the hollow. When the large shaft slides to the side of the limiting ring I, it is limited by the limiting ring I. When it slides to the side of the limiting ring II, it is limited by the limiting ring II. The small shaft passes through the limiting ring I and extends out of the opening.

[0017] Furthermore, the outer wall of the outer sleeve is larger than the hole wall of the limiting ring I;

[0020] The collar is fitted on the side of the outer shell away from the limiting ring I, and the bottom ring abuts against the end of the outer shell away from the limiting ring I. The part of the bottom ring located inside the large hole constitutes the limiting ring II.
[0021] Furthermore, the outer wall of the outer shell has external threads, and the inner wall of the collar has internal threads; the outer shell and the collar are screwed together by the external and internal threads.
[0022] Furthermore, the engaging structure is a regular polygonal hole wall located inside the small hole; the end of the encoder shaft is a regular polygonal shaft structure.
[0023] This utility model also provides an encoder control system, including an encoder shaft and the aforementioned stepping pin device;

[0025] Furthermore, the encoder shaft is located inside the return spring.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0036] As attached Figure 1 - Appendix Figure 3 As shown, this utility model provides a stepping nail device, including a housing 3, a reset tube 4, a reset spring 5, and a trigger element 2;
[0037] The outer shell 3 is hollow inside and open at both ends. One of the openings is equipped with a limiting ring I7 and the other opening is equipped with a limiting ring II8. Both the limiting ring I7 and the limiting ring II8 are annular structures. The outer wall is sealed to the opening and the inner wall is provided with a through hole.
[0038] The outer wall of the reset tube 4 has a stepped shaft structure, which includes a large shaft and a small shaft connected to each other. The outer wall of the large shaft is slidably disposed within the hollow space. When the large shaft slides to the side of the limiting ring I7, it is limited by the limiting ring I7; when it slides to the side of the limiting ring II8, it is limited by the limiting ring II8. That is, the large shaft can only slide within the hollow space and cannot slide out from the opening. The limiting rings I7 and II8 limit the sliding stroke of the large shaft. The small shaft of the stepped shaft passes through the limiting ring I7 and extends out of the opening. The small shaft is used for operation by the operator. The cross-sections of the large and small shafts can also be polygonal or circular. The cross-sectional shapes of the hollow inner wall of the outer shell 3 and the inner wall of the limiting ring I7 correspond to the cross-sectional shapes of the large and small shafts to achieve relative sliding between the large shaft and the hollow space, and between the small shaft and the limiting ring I7.
[0039] The inner wall of the reset tube 4 has a stepped hole structure, which includes a large hole and a small hole. Preferably, the stepped holes are arranged corresponding to the stepped shaft, so that the reset tube 4 has a thin-walled tubular structure. That is, the cross-sections of the large hole and the small hole can also correspond to the cross-sectional shapes of the large shaft and the small shaft, which can be polygonal or circular. The opening of the large hole faces the limiting ring II8. One end of the reset spring 5 abuts against the step of the stepped hole, and the other end abuts against the limiting ring II8. That is, the spring body of the reset spring 5 is located in the hollow of the outer shell 3, and part of it is located in the large hole. When the reset tube 4 moves downward toward the limiting ring II8, it will compress the reset spring 5. When the downward pressure is lost, the reset spring 5 will stretch and drive the reset tube 4 to reset.
[0040] A locking structure 41 is provided on the side of the small hole near the large hole for sliding engagement with the encoder shaft 9. The locking structure 41 is used to drive the encoder shaft 9 to rotate when the small shaft is rotated, triggering the rotation signal of the encoder shaft 9; that is, the locking structure 41 is used to engage the encoder shaft 9, so that the encoder shaft 9 and the small hole can only slide relative to each other along the axial direction, but cannot rotate relative to each other. When the small hole is polygonal, the end of the encoder shaft 9 will also be polygonal. In this case, the two engage so that the encoder shaft 9 and the small hole can only slide relative to each other along the axial direction, but cannot rotate relative to each other. That is, the inner wall of the small hole is directly the locking structure 41.
[0041] A trigger element 2 is installed inside the small hole. The trigger element 2 is used to trigger the pressure switch signal of the encoder shaft 9 when the large axial limit ring II 8 moves in the direction.
[0042] The stepper device provided by this utility model has a simple structure and strong integration. After being installed on the encoder shaft 9, it forms an integral part with the encoder shaft 9. It can be triggered by pressing down to activate the pressure switch signal of the encoder shaft 9, and by rotating to trigger the rotation signal of the encoder shaft 9. It is very convenient to adapt to the function of the encoder shaft 9. Moreover, the stepper device and the encoder shaft 9 are easy and quick to assemble and disassemble.
[0043] In one embodiment, the trigger 2 includes a trigger spring disposed within a small hole. Using a trigger spring as the trigger 2 offers advantages such as reliable triggering and rapid response. Furthermore, the contact between the trigger spring and the end of the encoder shaft 9 provides elastic buffering force, which can buffer and protect the encoder shaft 9 in cases of excessive downward pressure from the user (since users typically trigger by foot, the control of downward pressure may deviate). It also provides some tactile feedback, allowing the user to easily perceive the triggering status. In other embodiments, the trigger 2 can be a trigger block. In this case, when the trigger block touches the end face of the encoder shaft 9, it triggers the downward switch signal of the encoder shaft 9.
[0044] In one embodiment, the small hole is a through hole. The stepper device also includes a stepper head 1 fixedly mounted on the end of the small shaft. A trigger element 2 is mounted on the stepper head 1 and extends into the small hole. In this embodiment, the stepper head 1 is detachably connected to the small shaft of the reset tube 4, facilitating the disassembly and assembly of the trigger element 2 for maintenance. Furthermore, the trigger stroke of the trigger element 2 can be adjusted by varying the fixing depth between the stepper head 1 and the small shaft, thereby adjusting the trigger sensitivity. In other embodiments, the small hole can also be a blind hole. In this case, the trigger element 2 is fixedly mounted at the bottom of the blind hole to simplify the structure.
[0045] In one embodiment, the stepper head 1 includes a plate 11 and an outer sleeve 12 and an inner post 13 coaxially disposed at one end of the plate 11.
[0046] The outer sleeve 12 is fitted onto the end of the small shaft, and the inner column 13 is fitted into the end of the small hole. The inner wall of the outer sleeve 12 and the outer wall of the inner column 13 are fitted into the upper end of the reset tube 4 to improve the connection stability.
[0047] The trigger 2 is located at the end of the inner post 13. This arrangement increases the depth of the trigger 2 within the small hole, thereby reducing the travel distance of the trigger 2.
[0048] In one embodiment, the outer wall of the outer sleeve 12 is larger than the hole wall of the limiting ring I7;
[0049] The maximum distance from the outer sleeve 12 to the limiting ring I7 is shorter than the maximum distance from the main shaft to the limiting ring II8. That is, before the main shaft slides into the contact limiting ring II8, the end of the outer sleeve 12 abuts against the outside of the limiting ring I7 to achieve sliding limitation of the main shaft, avoiding excessive compression of the return spring 5, while ensuring the compression return stroke of the return spring 5. Alternatively, the maximum distance from the outer sleeve 12 to the limiting ring I7 is equal to the maximum distance from the main shaft to the limiting ring II8. In this case, when the main shaft slides into the contact limiting ring II8, the end of the outer sleeve 12 abuts against the outside of the limiting ring I7. This two-set abutment cooperation achieves sliding limitation of the main shaft in the hollow space, improving the structural stability when the return tube 4 is pressed to its maximum stroke.
[0050] In one embodiment, the stepping device further includes a bottom cover 6, which includes a bottom ring 61 and a collar 62 extending upward from the outer end of the bottom ring 61.
[0051] A collar 62 is fitted onto the side of the outer shell 3 opposite to the limiting ring I7, and a bottom ring 61 abuts against the end of the outer shell 3 opposite to the limiting ring I7. The portion of the bottom ring 61 located inside the large hole constitutes the limiting ring II8. In this embodiment, the limiting ring II8 can be detachably connected to the reset tube 4 via the bottom cover 6, thereby facilitating the disassembly and installation of the reset spring 5. Simultaneously, the axial position of the limiting ring II8 (the upper end of the bottom ring 61) can be adjusted, thereby adjusting the preload of the reset spring 5 in its initial state and adjusting the initial reset force of the stepper device.
[0052] In one embodiment, the outer wall of the outer shell 3 has external threads, and the inner wall of the collar 62 has internal threads; the outer shell 3 and the collar 62 are screwed together by the external and internal threads. In this embodiment, the threaded connection between the collar 62 and the outer shell 3 makes the connection stable and reliable, and also facilitates the adjustment of the axial position of the limiting ring II 8 (the upper end of the bottom ring 61).
[0053] In one preferred embodiment, refer to the appendix Figure 3 The engaging structure 41 is a regular polygonal hole wall located inside the small hole; the end of the encoder shaft 9 is a regular polygonal shaft structure. This design makes the engaging structure 41 simple and reliable. Furthermore, it is integrated with the reset tube 4, eliminating the need for separate components and reducing the installation difficulty of the reset tube 4 and the encoder shaft 9. In other embodiments, when the cross-section of the small hole is circular and the end of the encoder shaft 9 is cylindrical, the engaging structure 41 can be a keyway structure or a spline structure.
[0054] This utility model also provides an encoder control system, including an encoder shaft 9 and the above-mentioned stepping device;
[0055] The end of the encoder shaft 9 passes through the inner wall of the limiting ring II 8, the hollow of the outer shell 3, and the large hole, and then slides linearly with the engaging structure 41. The encoder control system provided by this utility model allows for convenient and quick assembly and disassembly of the encoder shaft 9 and the stepper device, ensuring installation efficiency and facilitating maintenance.
[0056] In one embodiment, the encoder shaft 9 is located inside the reset spring 5, that is, the reset spring 5 is sleeved on the outside of the encoder shaft 9. This guides the compression and reset of the reset spring 5, improving its operational stability. Preferably, the inner diameter of the reset spring 5 is larger than the outer diameter of the encoder shaft 9 to avoid frictional damage to the encoder shaft 9 caused by the reset spring 5.
[0057] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
