Description

Technical Field

[0001] This invention belongs to the field of pedal technology, and in particular relates to a foot pedal mounting structure. Background Technology

[0002] Foot pedals are a common component on motorcycles, mainly used to place the rider's feet. Existing foot pedals typically include a base, a connecting shaft, a pedal, and a locking assembly. The base is detachably mounted on the frame. The first end of the connecting shaft is fixed to the base. The pedal has a mounting hole. The second end of the connecting shaft passes through and extends out of the mounting hole of the pedal. The locking assembly is installed on the second end of the connecting shaft to connect the pedal to the base.

[0003] However, the existing pedals are fixedly mounted on the base, and the pedals cannot rotate relative to the base along the length of the connecting shaft. This makes it difficult for the rider's foot posture and the pedal surface to maintain a natural fit when the riding posture changes during actual riding, which can easily lead to uneven force distribution. Long-term use will affect the comfort and safety of pedaling. Summary of the Invention

[0004] The purpose of this invention is to provide a pedal mounting structure to solve the problem in the prior art that the pedals cannot adaptively conform to the rider's feet when the rider changes riding posture.

[0005] To achieve this objective, the present invention adopts the following technical solution: This invention provides a foot pedal mounting structure, comprising a base, a pedal, a connecting shaft, a locking assembly, and at least one buffer member, wherein: The base is mounted on the frame. The first end of the connecting shaft is detachably mounted on the base. The pedal has a mounting hole. The pedal is mounted on the connecting shaft through the mounting hole and abuts against the base. The second end of the connecting shaft extends out of the mounting hole. A locking assembly is mounted on the second end of the connecting shaft to mount the pedal on the connecting shaft and abut against the base. There is at least one receiving cavity between the base and the pedal, the receiving cavity extends in the circumferential direction, and a buffer is provided in each receiving cavity. The buffer in the receiving cavity is in a compressed state, the first end of the buffer abuts the base, the second end of the buffer abuts the pedal, and the buffer is configured in the circumferential direction to absorb the impact force on the pedal. When the rider steps on the pedal, the buffer can be further compressed by the force, so that the pedal rotates at a certain angle relative to the connecting shaft, thereby making the rider's foot fit in contact with the pedal surface.

[0006] Optionally, at least one first protrusion is provided on the end face of the base facing the pedal, and at least one first limiting surface is provided on the side wall of the first protrusion; A stepped hole is provided at one end of the mounting hole near the base. At least one second protrusion is provided on the stepped surface of the stepped hole. At least one second limiting surface is provided on the side wall of the second protrusion. The first protrusion and the second protrusion interfere with each other in the circumferential direction. After the pedal is installed in place, the first protrusion is inserted into the mounting hole to form at least one receiving cavity through the cooperation of the first limiting surface and the second limiting surface. Each buffer component corresponds to one receiving cavity.

[0007] Optionally, four buffer components are provided, and two second protrusions are symmetrically arranged on the step surface of the stepped hole, and two second limiting surfaces are symmetrically arranged on both sides of the second protrusions along the circumferential direction. Two first limiting surfaces are symmetrically arranged on both sides of the first protrusion along the circumferential direction. There are two first protrusions. After the pedal is installed in place, the two second protrusions are respectively inserted into the two gaps between the two first protrusions. Each first limiting surface and an adjacent second limiting surface combine to form a receiving cavity, thereby forming four receiving cavities evenly distributed along the circumferential direction.

[0008] Optionally, the buffer is configured as a spring, with the first end of the spring abutting against the first limiting surface and the second end of the spring abutting against the second limiting surface.

[0009] Optionally, both the first limiting surface and the second limiting surface are tilted towards the corresponding receiving cavity at a preset angle.

[0010] Optionally, the first protrusion is housed in the mounting hole, and the base is provided with a cylindrical section extending toward the pedal. The cylindrical section has a central hole through it along the axial direction. The first end of the connecting shaft passes through the central hole. Two first protrusions are symmetrically arranged on the end face of the cylindrical section near the pedal. The outer diameter of the cylindrical section is adapted to the diameter of the stepped hole.

[0011] Optionally, a sleeve located at the outer edge of the central hole is provided on the end face of the cylindrical section near the pedal. The sleeve extends axially, and two first protrusions are integrally formed on the outer wall of the sleeve. The second protrusion has the same length as the sleeve along the axial direction. The first limiting surface, the second limiting surface, the outer wall of the sleeve, and the inner wall of the stepped hole form a receiving cavity.

[0012] Optionally, a through hole is provided on the base, and a first external thread section is provided on the first end of the connecting shaft. The first end of the connecting shaft passes through the through hole and is locked and fixed on the base by a first nut.

[0013] Optionally, the locking assembly includes a second nut and an anti-rotation washer. The second end of the connecting shaft is provided with a second external thread section. After the pedal is installed in place, the second external thread section extends out of the mounting hole. The anti-rotation washer is fitted onto the second end of the connecting shaft. The second nut is installed on the second external thread section and locks the anti-rotation washer onto the pedal.

[0014] Optionally, a clearance hole is provided at the part of the pedal away from the base, the mounting hole is connected to the clearance hole, and the locking component is located in the clearance hole.

[0015] Compared with the prior art, the foot pedal mounting structure proposed in this invention has the following advantages: 1) The cushioning component enables an elastic connection between the pedal and the base along the circumferential direction, allowing the pedal to rotate at a preset angle along the axis of the connecting shaft. This ensures that the rider's feet are always in contact with the pedal surface when adjusting their riding posture, thus ensuring riding safety and comfort. 2) It can provide adaptive cushioning and shock absorption along the circumferential direction between the pedal and the base during riding, improving the reliability of the connection between the base and the pedal; 3) The compressed buffer provides elasticity when the pedal rotates, which not only automatically returns the pedal to its initial state after the rider releases the pedal, but also avoids hard contact between the pedal and the base in the circumferential direction, further improving the reliability and safety of the connection between the pedal and the base. 4) Multiple buffer components are set in the corresponding accommodating cavity, which can form multiple elastic buffer parts on the contact surface between the pedal and the base, thus improving the adaptive buffering effect of the pedal. 5) A spring that is always in a compressed state is used as a buffer to continuously provide pre-tightening force, ensuring buffering and anti-loosening effects while maintaining a simple structure; 6) The first limiting surface and the second limiting surface are set at a preset inclined angle, which makes it easier for the spring to provide elastic force in the circumferential direction and has a good buffering effect; 7) The first and second protrusions also have the functions of strengthening the connection between the pedal and the base and positioning the pedal in the axial direction.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1 to 7As shown in the figure, an embodiment of the present invention provides a foot pedal mounting structure, which includes a base 10, a pedal 20, a connecting shaft 30, a locking assembly 40, and at least one buffer member 50. The base 10 is mounted on the vehicle frame. The first end of the connecting shaft 30 is detachably mounted on the base 10. The pedal 20 has a mounting hole 21, through which the pedal 20 is mounted on the connecting shaft 30 and abuts against the base 10. The second end of the connecting shaft 30 extends out of the mounting hole 21. The locking assembly 40 is mounted on the second end of the connecting shaft 30 to mount the pedal 20 on the connecting shaft 30 and abut against the base 10. At least one receiving cavity 11 is provided between the base 10 and the pedal 20. The receiving cavity 11 extends in the circumferential direction. A buffer 50 is provided in each receiving cavity 11. The buffer 50 in the receiving cavity 11 is in a compressed state. The first end of the buffer 50 abuts against the base 10, and the second end of the buffer 50 abuts against the pedal 20. The buffer 50 is arranged in the circumferential direction to absorb the impact force on the pedal 20. When the rider steps on the pedal 20, the buffer 50 can be further compressed by force so that the pedal 20 rotates at a certain angle relative to the connecting shaft 30, thereby making the rider's foot fit in contact with the step surface of the pedal 20.

[0020] Specifically, the pedal 20 has anti-slip teeth 24 on its surface to increase friction when the rider pedals, prevent slipping, and improve safety.

[0021] Specifically, in the initial state, the pedal 20 maintains a predetermined angle with the base 10 under the elastic force of the buffer 50. When the rider steps on the pedal 20, the pedal 20 overcomes the elastic force of the buffer 50 and rotates relative to the base 10 by a certain angle. When the rider releases the pedal 20, the pedal 20 automatically returns to its original position under the elastic force of the buffer 50.

[0022] The compression buffer 50 achieves an elastic connection between the pedal 20 and the base 10 along the circumferential direction, allowing the pedal 20 to rotate at a preset angle along the axis of the connecting shaft 30. This ensures that the rider's foot remains in contact with the pedal surface when adjusting their riding posture, guaranteeing riding safety and comfort. It also provides adaptive cushioning and shock absorption along the circumferential direction between the pedal 20 and the base 10 during riding, improving the reliability of the connection between the base 10 and the pedal 20. Furthermore, it provides elasticity when the pedal 20 rotates, preventing hard contact between the pedal 20 and the base 10 along the circumferential direction, further enhancing the reliability and safety of the connection between the pedal 20 and the base 10.

[0023] In one embodiment, at least one first protrusion 12 is provided on the end face of the base 10 facing the pedal 20, and at least one first limiting surface 120 is provided on the side wall of the first protrusion 12; a stepped hole 210 is provided at one end of the mounting hole 21 near the base 10, and at least one second protrusion 211 is provided on the stepped surface 2100 of the stepped hole 210, and at least one second limiting surface 2110 is provided on the side wall of the second protrusion 211. The first protrusion 12 and the second protrusion 211 interfere with each other in the circumferential direction; after the pedal 20 is installed in place, the first protrusion 12 is inserted into the mounting hole 21 so as to form at least one receiving cavity 11 through the cooperation of the first limiting surface 120 and the second limiting surface 2110, and each buffer 50 corresponds to one receiving cavity 11.

[0024] The first protrusion 12 and the second protrusion 211 interfere in the circumferential direction, and the first limiting surface 120 and the second limiting surface 2110 together form a receiving cavity 11, which stably restricts the buffer 50 in the cavity, realizes the precise positioning and reliable guidance of the buffer 50, and ensures the stable and reliable buffering effect; the first protrusion 12 and the second protrusion 211 cooperate to enhance the connection strength between the base 10 and the pedal 20.

[0025] In one embodiment, four buffer members 50 are provided. Two second protrusions 211 are symmetrically arranged on the step surface 2100 of the step hole 210. Two second limiting surfaces 2110 are symmetrically arranged on both sides of the second protrusions 211 along the circumferential direction. Two first limiting surfaces 120 are symmetrically arranged on both sides of the first protrusions 12 along the circumferential direction. There are two first protrusions 12. After the pedal 20 is installed in place, the two second protrusions 211 are respectively inserted into the two gaps between the two first protrusions 12. Each first limiting surface 120 and an adjacent second limiting surface 2110 combine to form a receiving cavity 11, thereby forming four receiving cavities 11 evenly distributed along the circumferential direction.

[0026] By providing multiple buffer elements 50, multiple elastic buffer portions can be formed on the contact surface between the pedal 20 and the base 10, thereby improving the adaptive buffering effect of the pedal 20.

[0027] In one embodiment, the buffer 50 is configured as a spring, with the first end of the spring abutting against the first limiting surface 120 and the second end of the spring abutting against the second limiting surface 2110.

[0028] By using a spring that is always in a compressed state as the buffer element 50, a pre-tightening force is continuously provided, ensuring both buffering and anti-loosening effects while maintaining a simple structure.

[0029] In one embodiment, both the first limiting surface 120 and the second limiting surface 2110 are tilted at a preset angle toward the corresponding receiving cavity 11.

[0030] By setting the first limiting surface 120 and the second limiting surface 2110 to a preset tilt angle, the spring can provide elastic force in the circumferential direction, resulting in a good buffering effect.

[0031] In one embodiment, the first protrusion 12 is received in the mounting hole 21, and the base 10 is provided with a cylindrical section 13 extending toward the pedal 20. The cylindrical section 13 has a central hole 130 through it along the axial direction. The first end of the connecting shaft 30 passes through the central hole 130. The two first protrusions 12 are symmetrically arranged on the end face of the cylindrical section 13 near the pedal 20. The outer diameter of the cylindrical section 13 is adapted to the diameter of the stepped hole 210.

[0032] The cylindrical section 13 forms a radial positioning fit with the stepped hole 210, which improves the coaxiality of the assembly of the pedal 20 and the base 10, reduces radial sway, and improves the stability of the structure.

[0033] In one embodiment, a sleeve 14 located on the outer edge of the central hole 130 is provided on the end face of the cylindrical segment 13 near the pedal 20. The sleeve 14 extends axially, and two first protrusions 12 are integrally formed on the outer side wall of the sleeve 14. The second protrusion 211 has the same axial length as the sleeve 14. The first limiting surface 120, the second limiting surface 2110, the outer side wall of the sleeve 14, and the inner wall of the stepped hole 210 form a receiving cavity 11.

[0034] The first protrusion 12 is integrally formed on the outer wall of the sleeve 14, which makes the overall structure stronger and the positioning more accurate, facilitates the installation of the buffer 50, and improves the reliability and stability of the buffer.

[0035] In one embodiment, a through hole is provided on the base 10, and a first external thread section 36 is provided on the first end of the connecting shaft 30. The first end of the connecting shaft 30 passes through the through hole and is locked and fixed on the base 10 by the first nut 31.

[0036] Specifically, the through hole is set as an internal hexagonal hole, and the first nut 31 is set as a hexagonal nut that is compatible with the internal hexagonal hole.

[0037] The engagement of the first nut 31 with the first external thread section 36 provides a way to lock and fix the connecting shaft 30 and the base 10 using a threaded structure. The structure is simple and easy to disassemble and assemble.

[0038] In one embodiment, the locking assembly 40 includes a second nut 41 and an anti-rotation washer 42. The second end of the connecting shaft 30 is provided with a second external thread section 32. After the pedal 20 is installed in place, the second external thread section 32 is provided to prevent it from protruding from the mounting hole 21. The anti-rotation washer 42 is fitted onto the second end of the connecting shaft 30. The second nut 41 is installed on the second external thread section 32 and locks the anti-rotation washer 42 onto the pedal 20.

[0039] Specifically, the second nut 41 is a flange nut. The flange of the flange nut and the contact surface of the anti-rotation washer 42 are provided with anti-slip texture. The anti-rotation washer 42 is pressed and fixed on the connecting shaft 30 and the pedal 20 by the flange surface of the flange nut, which increases the pressing area and further improves the locking reliability of the second nut 41.

[0040] Specifically, the second end of the connecting shaft 30 is also provided with a limiting section 33, which is located at the end of the second external thread section 32 near the base 10. The outer diameter of the limiting section 33 is larger than the outer diameter of the second external thread section 32. Multiple snap-fit ​​grooves 330 are formed along the circumferential direction at the outer edge of the end face of the limiting section 33 near the second external thread section 32. A through hole 420 is formed in the middle of the anti-rotation washer 42. Multiple limiting blocks 421 are arranged at intervals along the circumferential direction in the through hole 420. Each limiting block 421 corresponds to a snap-fit ​​groove 330. When the second nut 41 is installed on the second external thread section 32 and the anti-rotation washer 42 is locked and fixed on the pedal 20, the limiting block 421 is set in the corresponding snap-fit ​​groove 330. Thus, the cooperation of multiple snap-fit ​​grooves 330 and multiple limiting blocks 421 prevents the connecting shaft 30 from rotating and limits the connecting shaft 30 in the axial and radial directions. This avoids the connecting shaft 30 from shifting under the action of impact force, causing the pedal 20 to loosen, and greatly improves the stability and reliability of the pedal 20 installation.

[0041] Specifically, the cross-section of the limiting block 421 is any one of circular, arc-shaped, or polygonal, and the locking groove 330 is any one of circular, arc-shaped, or polygonal that is compatible with the limiting block 421. This allows for flexible selection of the matching form between the limiting block 421 and the locking groove 330 according to actual working conditions, ensuring the stability and reliability of circumferential limiting.

[0042] Specifically, the connecting shaft 30 is also provided with a shoulder section 34, which is connected to the limiting section 33 and the outer diameter of the shoulder section 34 is larger than the outer diameter of the limiting section 33. The mounting hole 21 also includes a first hole 25 and a second hole 26. The outer diameter of the limiting section 33 is adapted to the diameter of the second hole 26, and the outer diameter of the shoulder section 34 is adapted to the diameter of the first hole 25. After the pedal 20 is installed in place, the shoulder section 34 is located in the first hole 25 to axially position the connecting shaft 30, thereby improving the assembly accuracy and structural rigidity between the connecting shaft 30 and the pedal 20 and reducing loosening gaps.

[0043] Specifically, the shoulder section 34 is provided with an external hexagonal section 35 at one end near the limiting section 33. The external hexagonal section 35 is used to cooperate with tools to install the second end of the connecting shaft 30.

[0044] Specifically, the tools can be wrenches, pliers, etc.

[0045] Specifically, the shoulder section 34 is connected to the limiting section 33 through the external hexagonal section 35.

[0046] The engagement of the second nut 41 with the second external thread section 32 provides a way to lock and fix the anti-rotation washer 42 using a threaded structure, which is simple in structure and easy to disassemble and assemble.

[0047] In one embodiment, a clearance hole 22 is provided at the part of the pedal 20 away from the base 10, the mounting hole 21 is connected to the clearance hole 22, and the locking component 40 is located in the clearance hole 22.

[0048] Specifically, the pedal 20 is also provided with weight-reducing holes 23 to reduce the weight of the pedal 20.

[0049] Preferably, two weight-reducing holes 23 are provided.

[0050] The step 20 has a clearance hole 22, which not only reduces weight, but also protects the locking component 40 by housing it inside the clearance hole 22, resulting in a neat appearance.

[0051] The general installation steps for the buffer structure used in pedal 20 are as follows: S1, insert the first end of the connecting shaft 30 into the through hole and thread it into the first nut 31 in the through hole; S2, Place the buffer 50 into the corresponding receiving cavity 11; S3, the second end of the connecting shaft 30 is passed through the mounting hole 21 so that the cylindrical section 13 extends into the stepped hole 210, and the second end of the connecting shaft 30 is set through the anti-rotation washer 42. S4, the second nut 41 is threaded onto the second external thread section 32 of the connecting shaft 30 to connect the anti-rotation washer 42, the connecting shaft 30, the pedal 20 and the base 10.

[0052] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above examples. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
