Description

Technical Field

[0001] This utility model belongs to the field of motorcycle parts technology, and more specifically, it relates to a quick-adjustable motorcycle rear seat pedal structure. Background Technology

[0002] In motorcycles used for passenger transport, passengers vary significantly in height, leg length, and riding habits, creating a demand for personalized adjustments to the height of the rear footrest. However, most existing motorcycle rear footrests use a fixed installation structure, leading to issues such as feet dangling, excessive knee bending, or instability when the footrest is too high or too low. This not only affects riding comfort but may also pose safety hazards during emergency braking or on bumpy roads.

[0003] Patent CN219487634U discloses a motorcycle rear seat pedal, but it is an electric adjustment solution, which is costly and unreliable; while mechanical solutions are often more cumbersome to adjust.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a quick-adjustable motorcycle rear foot pedal structure in order to achieve a more practical purpose. Utility Model Content

[0005] In view of the problems mentioned in the background art above, this utility model provides a quick-adjustable motorcycle rear seat pedal structure.

[0006] The technical solution adopted by this utility model is as follows: A quick-adjustable motorcycle rear seat pedal structure includes a mounting base, an adjusting vertical plate, a pedal part, and a plug-in part. The mounting base includes an integrally formed adjusting plate and a mounting plate, and the mounting plate has mounting holes. The adjusting vertical plate is slidably connected to the adjusting plate. The adjusting plate has a first dovetail groove, and the adjusting vertical plate is provided with a first dovetail block that matches the first dovetail groove. The adjusting plate has a plurality of adjusting holes, and the adjusting vertical plate has at least one connecting hole of a corresponding size to the adjusting holes. The pedal part is rotatably mounted on the top of the adjusting vertical plate via a damping shaft. The plug-in part is used to extend into the adjusting holes and the connecting hole to limit the position of the adjusting vertical plate.

[0007] Furthermore, the plug-in part includes a plug-in block and a torsion spring disposed at the bottom of the pedal part. The two ends of the torsion spring are respectively connected to the top of the plug-in block and the bottom of the pedal part. A plug-in post is connected to the plug-in block. The front end of the plug-in post is bent. The bent front end of the plug-in post is used to hook the adjustment hole and the connection hole when the pedal part and the adjustment plate are horizontal or vertical. The thickness of the adjustment plate is less than the thickness of the mounting plate.

[0008] Furthermore, the adjusting vertical plate has two connecting holes, which are threaded holes, and the adjusting vertical plate and the adjusting plate are connected by bolts.

[0009] Furthermore, the pedal section includes a connecting horizontal plate and a widening pedal. The connecting horizontal plate is rotatably connected to the adjusting vertical plate via a damping shaft, and the widening pedal is slidably connected to the connecting horizontal plate.

[0010] Furthermore, a second dovetail block is provided at the top of the connecting cross plate, and a second dovetail groove matching the second dovetail block is provided at the bottom of the widening pedal.

[0011] Furthermore, a limiting block is provided at the top end of the connecting cross plate, and a limiting groove matching the limiting block is provided at the bottom of the widening pedal.

[0012] Furthermore, a kick plate is provided at the end of the connecting cross plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. By designing the mounting base plate as an integrally formed adjustment plate and mounting plate, and setting a first dovetail groove on the adjustment plate to form a sliding pair with the first dovetail block on the adjustment vertical plate, the adjustment vertical plate can slide stably in the vertical direction without shaking or deflection; at the same time, multiple adjustment holes are opened on the adjustment plate and corresponding connection holes are opened on the adjustment vertical plate, and the limit is achieved by inserting the two through the plug-in part, thus constructing a mechanical adjustment system that can complete the height level switching without tools.

[0015] 2. The insertion part consists of an insertion block at the bottom of the pedal, a torsion spring, and a bent insertion post at the front end. When the pedal is in the horizontally extended or vertically retracted state, the bent structure at the front end of the insertion post aligns perfectly with the adjustment hole and the connection hole, and automatically inserts and hooks the two holes under the action of the torsion spring, forming a mechanical interlock. This design cleverly couples the pedal's flipping action with the insertion locking action: the user only needs to flip the pedal to the target position, and the insertion post will automatically complete the positioning under the drive of elastic force, without any additional operation. When height adjustment is required, the pedal is adjusted to the retracted state. At this time, simply press the end of the insertion block to bend the front end of the insertion post out of the connection hole and adjustment hole, adjust it to the appropriate position, release the insertion block, and the bent extension will hook into the two holes to complete the adjustment.

[0016] 3. Two connection holes are provided on the adjusting vertical plate, and the adjusting holes are designed as threaded holes, allowing users to selectively insert bolts through the connection holes and into the adjusting holes at any height setting to form a rigid threaded connection. In this state, the preload of the bolts establishes uniform compressive stress across the entire connection cross section, significantly improving the overall rigidity and shear resistance of the structure. Especially under long-term high-speed driving or heavy-load conditions, the bolt connection can effectively suppress fretting wear caused by metal fatigue or clearance accumulation, preventing the quick-adjustment mechanism from failing due to frequent use. Therefore, this solution, by retaining the quick-adjustment function while providing a bolt reinforcement option, meets the diverse needs of different users for convenience and safety.

Detailed Implementation

[0025] like Figures 1-5As shown, a quick-adjustable motorcycle rear footrest structure includes a mounting base plate 1, an adjusting vertical plate 2, a footrest portion 3, and a connecting portion. The mounting base plate 1 includes an integrally formed adjusting plate 11 and a mounting plate 12. The mounting plate 12 has mounting holes 121. The adjusting vertical plate 2 is slidably connected to the adjusting plate 11. The adjusting plate 11 has a first dovetail groove 112. The adjusting vertical plate 2 is provided with a first dovetail block 21 that matches the first dovetail groove 112. The adjusting plate 11 has a plurality of adjusting holes 111. The adjusting vertical plate 2 has at least one connecting hole 22 of a size corresponding to the adjusting hole 111. The footrest portion 3 is rotatably mounted on the top of the adjusting vertical plate 2 via a damping shaft 4. The connecting portion is used to extend into the adjusting holes 111 and the connecting hole 22 to limit the position of the adjusting vertical plate 2.

[0026] By adopting the above technical solution, the mounting base plate 1 is designed as an integrally formed adjustment plate 11 and mounting plate 12, and a first dovetail groove 112 is provided on the adjustment plate 11 to form a sliding pair with the first dovetail block 21 on the adjustment vertical plate 2, so that the adjustment vertical plate 2 can slide stably in the vertical direction without shaking or deflection; at the same time, multiple adjustment holes 111 are opened on the adjustment plate 11 and corresponding connection holes 22 are opened on the adjustment vertical plate 2, and the limit is achieved by inserting the two through the plug-in part, thereby constructing a mechanical adjustment system that can complete the height level switching without tools.

[0027] The top of the adjusting vertical plate 2 is also provided with a connecting block for supporting and limiting, ensuring that the bottom of the pedal part 3 rests against the connecting block after it is flipped over, thus avoiding excessive folding. The purpose of the damping pivot 4 is to ensure that the pedal part 3 does not fall off in the folded state.

[0028] As a preferred embodiment, the plug-in part includes a plug-in block 5 and a torsion spring 51 disposed at the bottom of the pedal part 3. The two ends of the torsion spring 51 are respectively connected to the top of the plug-in block 5 and the bottom of the pedal part 3. A plug-in post 52 is connected to the plug-in block 5. The front end of the plug-in post 52 is bent. The bent front end of the plug-in post 52 is used to hook the adjustment hole 111 and the connection hole 22 when the pedal part 3 and the adjustment plate 11 are horizontal or vertical. The thickness of the adjustment plate 11 is less than the thickness of the mounting plate 12.

[0029] By designing the mounting base plate 1 as an integrally formed adjustment plate 11 and mounting plate 12, and setting a first dovetail groove 112 on the adjustment plate 11 to form a sliding pair with the first dovetail block 21 on the adjustment vertical plate 2, the adjustment vertical plate 2 can slide stably in the vertical direction without shaking or deflection; at the same time, multiple adjustment holes 111 are opened on the adjustment plate 11 and corresponding connection holes 22 are opened on the adjustment vertical plate 2, and the limit is achieved by inserting the two through the plug-in part, thereby constructing a mechanical adjustment system that can complete the height level switching without tools.

[0030] The insertion part consists of an insertion block 5 at the bottom of the pedal part 3, a torsion spring 51, and a bent insertion post 52 at the front end. When the pedal part 3 is in the horizontally extended or vertically retracted state, the bent structure at the front end of the insertion post 52 aligns precisely with the adjustment hole 111 and the connection hole 22, and automatically inserts and hooks the two holes under the action of the torsion spring 51, forming a mechanical interlock. This design cleverly couples the pedal's flipping action with the insertion and locking action: the user only needs to flip the pedal to the target position, and the insertion post 52 will automatically complete the positioning under the drive of elastic force, without any additional operation. When height adjustment is required, the pedal part 3 is adjusted to the retracted state. At this time, only the end of the insertion block 5 needs to be pressed to bend the front end of the insertion post 52 out of the connection hole 22 and the adjustment hole 111, then adjusted to the appropriate position, and the insertion block 5 is released to allow the bent extension to hook the two holes, thus completing the adjustment.

[0031] As a preferred embodiment, the adjusting vertical plate 2 has two connecting holes 22, and the adjusting hole 111 is a threaded hole, which connects the adjusting vertical plate 2 and the adjusting plate 11 by bolts.

[0032] The adjusting vertical plate 2 is equipped with two connecting holes 22, and the adjusting hole 111 is designed as a threaded hole, allowing users to selectively insert a bolt through the connecting hole 22 and into the adjusting hole 111 at any height setting to form a rigid threaded connection. In this state, the preload of the bolt establishes uniform compressive stress across the entire connection cross section, significantly improving the overall rigidity and shear resistance of the structure. Especially under long-term high-speed driving or heavy-load conditions, the bolt connection can effectively suppress fretting wear caused by metal fatigue or clearance accumulation, preventing the quick-adjustment mechanism from failing due to frequent use. Therefore, this solution, by retaining the quick-adjustment function while providing a bolt reinforcement option, meets the diverse needs of different users for convenience and safety.

[0033] As a preferred embodiment, the pedal part 3 includes a connecting horizontal plate 31 and a widening pedal 32. The connecting horizontal plate 31 is rotatably connected to the adjusting vertical plate 2 via a damping shaft 4, and the widening pedal 32 is slidably connected to the connecting horizontal plate 31. A second dovetail block 311 is provided at the top of the connecting horizontal plate 31, and a second dovetail groove 321 matching the second dovetail block 311 is provided at the bottom of the widening pedal 32. A limiting block 312 is provided at the top end of the connecting horizontal plate 31, and a limiting groove 322 matching the limiting block 312 is provided at the bottom of the widening pedal 32.

[0034] The pedal part 3 is composed of a connecting horizontal plate 31 and a widening pedal 32. The two form a sliding pair through the second dovetail block 311 and the second dovetail groove 321, so that the widening pedal 32 can extend and retract laterally to adapt to different foot widths or sitting postures. The end of the connecting horizontal plate 31 is provided with a limiting block 312, and the bottom of the widening pedal 32 is provided with a corresponding limiting groove 322. When the widening pedal 32 is fully pulled out, the limiting block 312 is embedded in the limiting groove 322 to form a mechanical stop and prevent it from accidentally coming out. Because the dovetail structure has a self-locking characteristic, when the passenger's foot applies downward pressure, the contact surface between the widened pedal 32 and the connecting cross plate 31 will generate a normal reaction force. The horizontal component of this reaction force will further press the dovetail mating surface, thereby achieving load self-locking without the need for additional locking components. At the same time, the cooperation between the limiting groove 322 and the limiting block 312 not only provides protection at the end of the stroke, but also bears shear loads when subjected to lateral forces, preventing the sliding pair from jamming or deforming due to unilateral forces, and significantly improving the stability and durability of the pedal lateral adjustment.

[0035] As a preferred embodiment, the connecting cross plate 31 is provided with a kicking part 33 at its end. The kicking part 33 at the end of the connecting cross plate 31 protrudes from the outside of the pedal part 3, making it convenient for passengers to step on or kick the pedal with their toes when getting on and off the vehicle, so that it can be unfolded or flipped upwards and retracted.

It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
