Description

Technical Field

[0001] The invention relates to a pedal, in particular to a foot pedal structure. Background Art

[0002] Pedals are used in many fields, but are particularly important in motorcycles and scooters. Traditional pedals are heavy, prone to rust, and have low rigidity. Damaged pedals require complete replacement. Even if partial replacements are available, the components are often bulky. To reduce costs and extend lifespans, some products are considering modular designs. However, under conditions of frequent vibration and outdoor exposure, these can still become loose, corrode, and crack, making their effectiveness relatively limited. Summary of the Invention

[0003] In view of the deficiencies in the existing technology, the present invention provides a foot pedal structure.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a foot pedal structure, including a pedal body, the pedal body is composed of at least three parts: a tread plate, a pedal main frame and a connecting sub-frame. The tread plate is against the top surface of the pedal main frame and the connecting sub-frame and is fixedly assembled by a fastener. The pedal main frame and the connecting sub-frame are fixedly connected. The pedal main frame includes a secondary rod, a main rod, an inner corner piece and an outer corner piece. The secondary rod and the connecting sub-frame are fixedly connected by the outer corner piece. The secondary rod and the main rod are fixedly connected by the inner corner piece. The secondary rod, the main rod and the connecting sub-frame all include unit profiles. The unit profile is provided with a mounting groove on the end face other than the longitudinal direction. The mounting groove passes through the unit profile along the longitudinal direction. The mounting groove extends to the surface of the unit profile to form a notch with a narrowed width. The mounting groove and the notch form a positioning groove for sliding engagement. The mounting groove is provided with at least two parallel ends on the end face of the unit profile in the width direction.

[0005] The center of the unit profile is hollowed out along the length direction to form a hexagonal hollow groove. The installation groove is an inverted isosceles trapezoid.

[0006] The unit profile connecting the sub-frame is further provided with a fixedly connected limit cover and a second fastener on the end faces in the length and height directions.

[0007] The pedal main frame is in an arch bridge shape. The tread plate is in an isosceles trapezoidal structure, covering the pedal main frame and conforming to its shape and contour. The tread plate is provided with a connection portion connected to the connecting sub-frame at one outer edge.

[0008] The outer corner piece is provided with a penetrating fixing hole, a waist hole for adjusting the telescopic length and an inclined portion on the protruding surface on the same end surface, and the inclined portion is provided with an oblique hole for connecting the auxiliary rod.

[0009] The inner corner piece has an adjacent curved surface and a receiving portion. The curved surface and the receiving portion have an interlocking groove formed at the corner of their contours for the main rod to engage. The curved surface has a fan-shaped arc block structure. The curved surface has a first connecting hole at the outer edge of one side of the curved surface that extends obliquely through to the flat surface. The receiving portion has a second connecting hole for securing the main rod.

[0010] The tread plate is made of aluminum through an integrated engraving and milling process using a CNC machine tool. The pedal body is made of 6061-T6 aluminum profile.

[0011] The beneficial effects of the present invention are as follows: the pedal structure provided by the present invention is novel, lightweight, high-strength, corrosion-resistant and modular; inspired by the luggage rack, 6061-T6de aluminum profile is adopted, and the pedal area on the surface is engraved and milled with CNC aluminum alloy in one piece, and convex milling is used to facilitate daily car washing in the later stage, and enhance the texture of the logo and anti-slip performance; the connecting part of the aluminum profile is also made of CNC and fixed on the car body instead of the beam, so that the ground clearance can be higher; modularization can replace damaged small accessories separately, making the cost of playing with the car lower and extending the service life, and in the later stage it can be integrated with lighting tools for quick release; the key quick release aspect is that the pedal position can be adjusted according to personal needs, and the pedal can be easily removed according to different road conditions and other advantages.

[0018] like Figures 1-6As shown, a foot pedal structure includes a pedal body, and the pedal body is composed of at least three parts: a pedal panel 1, a pedal main frame 2, and a connecting sub-frame 3. In this embodiment, two pedal main frames 2 are provided, which can also be slid and adjusted as needed. The pedal body can be installed and fixed directly on the vehicle shell, and will not cause excessive burden on the vehicle shell due to its lightweight design. The pedal panel 1 rests on the top surface of the pedal main frame 2 and the connecting sub-frame 3 and is fixedly assembled by a fastener 1. The fastener 1 can be a threaded part, which is evenly spaced along the outer edge of the pedal panel 1. The pedal main frame 2 and the connecting sub-frame 3 are fixedly connected. The pedal main frame 2 includes a sub-rod 21, a main rod 22, an inner corner piece 23, and an outer corner piece 24. The modularization of each key part is conducive to improving the structural strength and service life of the risk point. At the same time, it is also convenient for disassembly and replacement. The auxiliary rod 21 is fixedly connected to the connecting sub-frame 3 via an outer corner fitting 24, and the auxiliary rod 21 is fixedly connected to the main rod 22 via an inner corner fitting 23. The auxiliary rod 21, main rod 22, and connecting sub-frame 3 all include a unit profile 4. The unit profile 4 has a mounting groove 41 on its end surface other than the longitudinal direction. The mounting groove 41 passes through the unit profile 4 along the longitudinal direction and extends toward the surface of the unit profile 4 to form a narrowing notch 42. The mounting groove 41 and the notch 42 form a positioning groove for sliding engagement. The mounting groove 41 has at least two parallel positioning grooves on the widthwise end surface of the unit profile 4. The unit profile 4 is easy to process and install. Two positioning grooves are provided on the main mounting surface on the side, facilitating the connection and fixation of rows of fasteners and enhancing structural stability. The positioning grooves can be adjusted by sliding and also serve as a limit stop to prevent disengagement, which is also a difference from general modularization. It should be noted that, in this embodiment, the main rod 22 , the auxiliary rod 21 and the connecting auxiliary frame 3 all adopt the basic material of the unit profile.

[0019] The unit profile 4 is hollowed out in the center along the length direction to form a hexagonal hollow groove 43, and the installation groove 41 is an inverted isosceles trapezoid. Under the premise of ensuring reliability in use, reducing the solidity is conducive to improving the level of lightweight. The shape of the installation groove 41 is conducive to full fit assembly, reducing vibration and collision in the gap, and enhancing the overall effect. The unit profile 4 connected to the sub-frame 3 is also provided with a fixedly connected limit cover 31 and a fastener 2 on the end face in the length and height directions. The limit cover 31 can limit the disengagement of the adjustment component and the disintegration of the foot pedal to a certain extent, thereby improving safety in use. It should be noted that fastener 1 and fastener 2 can be threaded parts, or deformations with external threads, or other structures that meet the needs of use. The scope is wide, so no excessive elaboration or limitation is made.

[0020] The pedal main frame 2 has an arched bridge structure, while the tread plate 1 is an isosceles trapezoidal structure. The tread plate 1 overlies the pedal main frame 2 and conforms to its shape and contours. A connection portion 11 is provided on one outer edge of the tread plate 1, connecting to the connecting sub-frame 3. The pedal body is generally small in size, and the connection at the outer edge is sufficient to meet design and usage requirements. Therefore, in this embodiment, no additional intermediate support structures are required to increase design complexity. Furthermore, the arched bridge structure can also withstand lateral impacts, improving rigidity.

[0021] The outer corner piece 24 has a through-hole 241, a waist hole 242 for adjusting the telescopic length, and a protruding bevel 243 on the same end surface. The bevel 243 includes an oblique hole 244 for connecting the secondary rod 21. The fixing hole 241 is directly fixed to the connecting sub-frame 3, while the oblique hole 244 connects to the secondary rod 21, providing a steering parallel connection. In this embodiment, the triangular bevel 243 is also designed to enhance the thickness and structural strength of this area, reducing the possibility of cracking.

[0022] The inner corner fitting 23 comprises an adjacent curved surface 231 and a receiving portion 232. The corners of the curved surface 231 and receiving portion 232 form a groove 233 for the main rod 22 to engage. The curved surface 231 also serves as a deflection and connection point, while also effectively distributing force against upward impacts. The inner corner fitting 23 exerts a relatively outward supporting force on the main rod 22, thus indirectly protecting the main rod 22 and other components, thereby increasing its service life.

[0023] The curved portion 231 has a fan-shaped arc-shaped block structure. A connecting hole 234 is provided on the outer edge of one side of the curved surface, extending obliquely through to the flat surface. The receiving portion 232 is provided with a connecting hole 235 for securing the main rod 22. Connecting hole 234 connects to the secondary rod 21 and is angled relative to the main rod 21, facilitating direct docking with the flat surface. The tread plate 1 is integrally formed from aluminum using CNC machine tools, with the convex milling providing a high-quality finish.

[0024] The pedal body is made of 6061-T6 aluminum. 6061-T6 aluminum, whose primary alloying elements include magnesium and silicon, offers excellent corrosion resistance and weldability. It exhibits excellent strength, corrosion resistance, and uniformity. This alloy undergoes solution heat treatment followed by artificial aging to achieve the T6 temper, resulting in high hardness and strength (reaching HV90 and above). It is widely used in various industrial structural components requiring high strength and corrosion resistance, such as trucks, tower buildings, ships, trams, railway vehicles, furniture machinery parts, precision machining, and molds.
