Description

Technical Field

[0001] This utility model relates to the field of vehicle suspension system technology, specifically to a quick-release scale self-calibrating damping adjustment knob for a shock absorber. Background Technology

[0002] The standard damping adjustment knob is used for adjusting the damping of nitrogen shock absorbers, and is especially suitable for modified car shock absorbers that achieve rapid adjustment of damping force through mechanical gears.

[0003] In mainstream threaded adjustment knobs, the knob and valve core are mechanically linked through a threaded connection. Since threaded connections inevitably have tolerance clearances, typically 0.1-0.3mm, when the knob is tightened to its final position, its circumferential angle experiences uncontrollable random offset. This directly leads to the arrow indication engraved on the outer casing not accurately aligning with the adjustment knob's gear markings, resulting in ambiguous gear selection and even inconsistent gear positions for the left and right shock absorbers, severely impacting vehicle handling stability. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a quick-release scale self-calibrating damping adjustment knob for a vibration damper.

The adjustment seat assembly includes an adjustment seat, and the adjustment valve core is coaxially disposed at the center of the adjustment seat and has a corrugated adjustment groove on its circumferential surface. The adjustment seat has a pin hole radially opened, and the cylindrical pin passes through the pin hole and is inserted into the corrugated adjustment groove to realize the gear function when the adjustment valve core rotates relative to the adjustment seat. The nut cover is threaded to the upper end of the connecting sleeve and presses the adjustment seat assembly against the connecting sleeve. The upper end of the adjustment valve core passes through the nut cover and is connected to the adjustment knob.

[0006] In some embodiments, the corrugated adjustment groove is opened circumferentially along the outer circumferential surface of the regulating valve core, and includes two end portions and several continuous and repeated arcuate surfaces and transition planes between the two end portions. Each time the cylindrical pin rotates into an arcuate surface, it forms a gear.

[0007] In some embodiments, the upper end face of the connecting sleeve is provided with an indicator arrow.

A locking bolt is inserted into the second channel and passes through the first channel and the threaded hole to connect, so that the regulating valve core rotates synchronously with the regulating knob.

[0010] In some embodiments, a dustproof pad is provided on the top of the second channel.

[0011] In some embodiments, the nut cap is provided with a connecting post, the adjusting knob is provided with a groove that adapts to the connecting post, and a third sealing ring is provided between the connecting post and the groove.

[0020] It should be noted that the terms "in some embodiments," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in some embodiments," "exemplarily," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner, meaning that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of this application.

[0021] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0023] like Figures 1 to 6 As shown, this application provides a quick-install self-calibrating damper damping adjustment knob, including a connecting sleeve 1, an adjustment seat assembly 2, an adjustment valve core 3, a cylindrical pin 4, a nut cover 5, and an adjustment knob 6. The connecting sleeve 1 is externally connected to the damper oil pipe and cylinder, providing a mounting and connection base for the entire adjustment knob.

[0024] The adjusting seat assembly 2 is disposed within the connecting sleeve 1 and includes an adjusting seat 20. Before overall assembly, the valve system of the adjusting seat assembly 2 must be assembled first to ensure that it can function normally during the damping adjustment of the shock absorber. The specific structure of the adjusting seat assembly 2 can be referenced from similar products in this technical field and is not limited here.

[0025] Because traditional adjustment knobs rely on a simple planar threaded clamping structure and lack a physical positioning mechanism, the continuous vibration during vehicle operation causes the valve core to shift slightly, resulting in unexpected slippage of the preset gear.

[0026] In some embodiments, the regulating valve core 3 is coaxially disposed at the center of the regulating seat 20, and a corrugated adjusting groove 30 is provided on its circumferential surface. The regulating seat 20 is radially provided with a pin hole 200. The cylindrical pin 4 passes through the pin hole 200 and is inserted into the corrugated adjusting groove 30 to realize the gear function when the regulating valve core 3 rotates relative to the regulating seat 20. The nut cover 5 is threadedly connected to the upper end of the connecting sleeve 1 and presses the regulating seat assembly 2 against the connecting sleeve 1 to prevent it from displacing in the circumferential direction, thereby eliminating the circumferential offset caused by the thread assembly gap. The upper end of the regulating valve core 3 passes through the nut cover 5 and is connected to the adjusting knob 6, so that the rotation of the adjusting knob 6 can drive the regulating valve core 3 to rotate synchronously, thereby realizing the damping adjustment.

[0027] The corrugated adjustment groove 30 is circumferentially opened along the outer circumference of the regulating valve core 3. It includes two end portions 300 and several continuous and repeated arc surfaces 301 and transition planes 302 between the two end portions 300. Normally, only the lower end surface of the corrugated adjustment groove 30 needs to be provided with the arc surfaces 301 and transition planes 302. Each time the cylindrical pin 4 rotates into an arc surface 301, it forms a gear. The arc surface 301 provides stable support and positioning for the cylindrical pin 4, and the transition plane 302 facilitates the switching of the cylindrical pin 4 between different gears.

[0028] Preferably, the coupling design of the corrugated adjustment groove 30 and the cylindrical pin 4 produces a clear mechanical positioning feel when the regulating valve core 3 rotates a certain angle, such as 40°, accompanied by a crisp sound feedback. This design forms a clear physical positioning mechanism, effectively avoiding the gear slippage problem caused by the lack of positioning in traditional mechanisms, making the gear perception clearer, enabling the driver to accurately judge the current gear, and ensuring the accuracy of the shock absorber damping adjustment.

[0029] In addition, the two end portions 300 can limit the extreme position of adjustment, and their shape is adapted to the cylindrical pin 4 to prevent over-adjustment from damaging the mechanism.

[0030] In some embodiments, the upper end of the regulating valve core 3 is provided with a connecting portion 31, and the end face of the connecting portion 31 is provided with a threaded hole 32. The regulating knob 6 is provided with a connecting groove 60 adapted to the connecting portion 31. A first channel 61 and a second channel 62 are sequentially provided above the connecting groove 60. The inner diameter of the first channel 61 is smaller than the inner diameter of the second channel 61. A locking bolt 11 is inserted into the second channel 62 and passes through the first channel 61 and the threaded hole 32 to connect them, so that the regulating valve core 3 rotates synchronously with the regulating knob 6. The connection method of the locking bolt 11 is simple and reliable, and easy to assemble and disassemble. The connecting portion 31 and the connecting groove 60 can have various shapes, such as polygonal or incomplete cylindrical shapes. This structure serves as a connecting hub for the regulating knob 6 to drive the regulating valve core 3 to rotate synchronously, avoiding rotational force acting on the locking bolt 11 and causing the locking bolt 11 to loosen.

[0031] Furthermore, a dustproof pad 9 is provided on the top of the second channel 62 to effectively block dust, impurities and other contaminants from entering the second channel 62 and the first channel 61, preventing dust from adhering to the locking bolt 11, avoiding loosening or damage of the locking bolt 11 due to dust corrosion, ensuring the stability and reliability of the locking bolt 11 connection, extending the service life of the adjustment mechanism, and reducing maintenance costs.

[0032] In some embodiments, the upper end face of the connecting sleeve 1 is provided with an indicator arrow 100. Existing structures require assembly workers to manually add or remove shims after thread pre-tightening to adjust for angular deviations caused by thread tolerance gaps. This process typically requires repeating the tightening and loosening cycle 3-5 times. With the above configuration, the indicator arrow 100 aligns with the gear scale on the adjusting knob 6. During assembly, the adjusting valve core 3 is first pressed into the matching adjusting seat assembly 2, and then the cylindrical pin 4 is installed from the side to axially limit and fix the adjusting seat assembly 2 and the adjusting valve core 3. Then, the cylindrical pin 4 is aligned with the indicator arrow 100 on the end face of the connecting sleeve 1 and pressed into the connecting sleeve 1. Finally, the nut cover 5 is locked. When the nut cover 5 is locked, the assembly consisting of the adjusting seat assembly 2, the adjusting valve core 3, and the cylindrical pin 4 will not experience circumferential displacement, thus eliminating circumferential offset caused by thread assembly gaps. Meanwhile, the assembly efficiency is improved by using a three-step process of "visual alignment → axial pressing → nut locking". Finally, the assembly is completed by sequentially assembling the adjustment knob 6, locking bolt 11, and dustproof pad 9. This eliminates the need to manually add or remove shims to adjust for angular deviations and reduces the number of tightening and loosening cycles. This assembly process greatly simplifies the operation steps, significantly improves assembly efficiency, and reduces labor costs.

[0033] In some embodiments, a first sealing ring 7 is provided between the adjusting seat 20 and the connecting sleeve 1, and a second sealing ring 8 is provided between the adjusting seat 20 and the adjusting valve core 3. The first sealing ring 7 and the second sealing ring 8 are located above the corrugated adjusting groove 30. The function of the first sealing ring 7 is to enhance the sealing between the adjusting seat 20 and the connecting sleeve 1, preventing external dust, moisture, impurities, etc. from entering the interior of the connecting sleeve 1, avoiding contamination and corrosion of components such as the adjusting seat assembly 2, and ensuring the normal operation of the adjusting mechanism. The second sealing ring 8 is used to enhance the sealing between the adjusting seat 20 and the adjusting valve core 3, extending the service life of the mechanism. Placing the two sealing rings above the corrugated adjusting groove 30 can effectively protect the corrugated adjusting groove 30 and key gear adjusting components such as the cylindrical pin 4, preventing them from being contaminated and damaged, and ensuring the smoothness and reliability of gear adjustment.

[0034] In some embodiments, the nut cap 5 is provided with a connecting post 50, and the adjusting knob 6 is provided with a groove 63 that adapts to the connecting post 50. A third sealing ring 10 is provided between the connecting post 50 and the groove 63. The third sealing ring 10 serves a sealing function, preventing external dust, moisture, etc. from entering the interior through the gap between them. Together with the first sealing ring 7 and the second sealing ring 8, it forms a multi-layer sealing protection, further improving the sealing performance and dustproof and waterproof performance of the adjusting mechanism, and ensuring the normal operation of the mechanism in harsh environments.

[0035] In some embodiments, a track groove 33 is provided circumferentially on the outer circumferential surface at the lower end of the regulating valve core 3, and a first through hole 201 is provided radially on the regulating seat 20 corresponding to the track groove 33, and the track groove 33 gradually decreases in size along its opening direction.
