Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bicycle pedals, specifically a front pedal device for a folding electric bicycle. Background Technology
[0002] Most folding electric bicycles on the market, especially those commonly used in the ride-hailing industry, retain a human-powered system consisting of left and right cranks, pedals, chainrings, and a chain. However, in actual use, ride-hailing drivers rely almost entirely on electric power, leaving the human-powered system largely idle, and its structural layout is clearly unreasonable.
[0003] First, regarding pedal position, the pedals of existing electric bicycles are typically located directly below the seat, with the cranks arranged in a forward-backward layout. This results in the angle between the rider's lower leg and thigh being generally less than 60° when pedaling, and for taller riders, this angle is even only about 50°. Second, regarding riding posture, because the pedals are positioned too far back, the rider's upper body needs to lean forward naturally, shifting the overall center of gravity forward. During emergency braking, it is difficult for the rider to quickly move their feet off the pedals and onto the ground, increasing the risk of accidents. Utility Model Content
[0004] The purpose of this invention is to provide a front pedal device for a folding electric bicycle to solve the problem of increased driving danger mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A front pedal device for a folding electric bicycle includes a main mounting steel frame and two extension mounting brackets. The main mounting steel frame is mounted on the top of the frame crossbeam of the folding electric bicycle. A fixing hole is provided on the top of the main mounting steel frame. The main mounting steel frame is detachably connected to the top of the frame crossbeam of the folding electric bicycle via bolts engaging with the fixing hole. The two extension mounting brackets are respectively connected to both sides of the main mounting steel frame. The two extension mounting brackets are located on both sides of the frame crossbeam of the folding electric bicycle, clamping the frame crossbeam. Mounting holes for mounting the front pedals are provided on the extension mounting brackets. The mounting holes are located below the frame crossbeam and close to the front wheel.
[0007] With the main mounting frame and two extension mounting brackets, the main mounting frame is installed on the top of the frame crossbeam and connected to the fixing holes with bolts. The extension mounting brackets are clamped on both sides of the frame crossbeam and form the foot pedal mounting position below. This helps to move the foot pedal position from under the seat to the area closer to the front wheel, so that the leg angle can be increased to more than 90° while maintaining a straight waist during riding.
[0008] Optionally, the main mounting steel frame and the two extension mounting frames are integrally formed; when in the unbent state, the top surface of the structure formed by the main mounting steel frame and the two extension mounting frames is an isosceles trapezoid; when in the bent state, the extension mounting frames are bent towards the crossbeam of the frame to form a right-angled trapezoidal structure.
[0009] By integrating the main mounting steel frame and the extended mounting frame into a single unit and bending them into a right-angled trapezoidal structure, the two right-angled trapezoidal surfaces after bending can stably fit against both sides of the vehicle frame crossbeam. This helps to improve the overall structural strength and stress balance of the mounting frame, achieving a stable installation effect when clamping crossbeams of different specifications.
[0010] Optionally, the extension mounting bracket has a limiting screw hole; the limiting screw hole is located above the mounting hole and below the frame crossbeam; a reinforcing screw is passed through the two opposite limiting screw holes of the two extension mounting brackets by a nut; the reinforcing screw is located below the frame crossbeam.
[0011] By creating a limiting screw hole on the extension mounting bracket and installing a reinforcing screw below it, the reinforcing screw passes horizontally under the crossbeam and is locked by a nut. This helps prevent the extension mounting bracket from flaring outward when the pedal bears the force of the pedal, thus maintaining stable clamping force and preventing loosening during riding.
[0012] Optionally, the acute angle of the right-angled trapezoidal structure of the extension mounting bracket is the bottom of the extension mounting bracket; the mounting hole is located at the acute angle; the outer corner of the acute angle is rounded; two opposite mounting holes are used to insert double-ended screws; the ends of the double-ended screws extend out of the mounting holes and are connected to a foot pedal.
[0013] By creating mounting holes at the sharp corners of the extended mounting bracket and using rounded corners, and inserting double-ended screws through the two opposing mounting holes and extending outwards to connect to the foot pedal, it helps to avoid stress concentration at the sharp corners that could cause cracks in the steel frame, thus achieving a secure foot pedal fixation and extended operating life.
[0014] Optionally, both ends of the double-ended screw are secured by flange nuts, which limit the length of the double-ended screw extending beyond the mounting holes.
[0015] By setting flange nuts at both ends of the double-ended screw, the flange nuts limit the extension length of the double-ended screw and have the feature of anti-slip surface facing outward, which helps to keep the left and right extension lengths of the pedal consistent, and achieve the effects of pedal balance, fine-tunable angle and stable riding posture.
[0016] Optionally, the fixing holes are arranged in a strip shape, and a gasket is provided at the fixing hole. The gasket cooperates with the bolt to strengthen the connection between the main mounting steel frame and the frame crossbeam.
[0017] By using strip-shaped holes for fixing and placing stainless steel shims in the holes, the strip-shaped holes can accommodate fine adjustments to the installation position, and the shims increase the stress area and prevent bolts from damaging the crossbeam. This helps to improve the connection strength between the main mounting steel frame and the crossbeam, achieving a reliable and non-loosening effect during long-term use.
[0018] Optional, the pedals are folding pedals.
[0019] By using folding pedals, the pedals can be unfolded when riding and folded when storing. This helps to maintain the pedal function without increasing lateral space, achieving the effect of not affecting the overall bike when folding and storing, and making it easy to carry.
[0020] Optionally, the spacing between the right-angled trapezoidal surfaces of the extension mounting bracket can range from 33mm to 38mm.
[0021] By limiting the spacing between the right-angled trapezoidal surfaces of the extension mounting bracket to 33mm to 38mm, which covers the common thickness range of crossbeams in commercially available folding electric bicycles, the universality and adaptability of the device are improved, allowing users to install it without modifying the frame.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-2 This utility model provides an embodiment of a front pedal device for a folding electric bicycle, comprising a main mounting steel frame 1 and two extension mounting brackets 2. The main mounting steel frame 1 is mounted on the top of the frame crossbeam of the folding electric bicycle. A fixing hole 3 is provided on the top of the main mounting steel frame 1, and the main mounting steel frame 1 is detachably connected to the top of the frame crossbeam by bolts engaging with the fixing holes 3. The two extension mounting brackets 2 are respectively connected to both sides of the main mounting steel frame 1, and are located on both sides of the frame crossbeam, clamping the frame crossbeam. Mounting holes 4 for mounting the front pedals are provided on the extension mounting brackets 2, and the mounting holes 4 are located below the frame crossbeam and near the front wheel.
[0028] In a further structural design, the main mounting steel frame 1 and the two extension mounting frames 2 can be integrally formed. In the unbent state, the top surface of the structure formed by the main mounting steel frame 1 and the two extension mounting frames 2 is an isosceles trapezoid; in the bent state, the extension mounting frames 2 bend towards the crossbeam of the frame to form a right-angled trapezoidal structure, thereby adapting to the clamping of both sides of the crossbeam of the frame.
[0029] The extension mounting bracket 2 also has a limiting screw hole 5, which is located above the mounting hole 4 and below the frame crossbeam. A reinforcing screw 6 is inserted between the relative limiting screw holes 5 of the two extension mounting brackets 2 and locked with a nut. The reinforcing screw 6 is located below the frame crossbeam to further reinforce the clamping of the extension mounting bracket 2.
[0030] Based on the above, the acute angle of the right-angled trapezoidal structure of the extended mounting bracket 2 forms its bottom, and the mounting hole 4 is located at this acute angle. The outer corner of the acute angle is rounded to reduce stress concentration. Two oppositely arranged mounting holes 4 are used to pass through double-ended screws 7, with both ends of the double-ended screws 7 extending out of the mounting holes 4, and the protruding parts are used to install the foot pedal.
[0031] The two ends of the double-ended screw 7 are fixed by flange nuts, which limit the length of the double-ended screw 7 extending out of the mounting holes 4, thereby ensuring the stability and balance of the foot pedal installation.
[0032] The fixing holes 3 of the main mounting steel frame 1 are preferably of a strip-shaped structure. An arc-shaped hole 8 is provided on the side of the main mounting steel frame 1 near the handlebar linkage to mate with the strip-shaped hole, allowing for greater adjustment space during the installation of the main mounting steel frame 1. A washer 10 is provided at the fixing hole 3, and the bolt is locked to the frame crossbeam through the washer 10 to enhance the connection strength between the main mounting steel frame 1 and the frame crossbeam.
[0033] In this embodiment, the pedals are folding pedals, which facilitate switching between riding and storage, ensuring that the vehicle's folding function is not affected.
[0034] Furthermore, the spacing between the two right-angled trapezoidal surfaces of the extension mounting bracket 2 is limited to 33mm to 38mm to accommodate frame beams of different thicknesses.
[0035] Based on the aforementioned structure, the device is installed using the existing holes in the frame crossbeams, eliminating the need for permanent modifications to the vehicle body and thus enabling it to be compatible with various models of folding electric bicycles. This design not only simplifies the installation process but also ensures the integrity and reversibility of the overall vehicle structure.
[0036] In addition, the extension mounting bracket 2 may also be provided with a perforated structure 9, which consists of openings distributed in the middle of the plate of the extension mounting bracket 2. This perforated structure 9 helps to reduce the overall weight of the device, reduce the additional load on the frame crossbeam, facilitate drainage and prevent dirt accumulation in rainy environments, and enhance the aesthetics of the structure.
[0037] With the above structural design, the front pedal device of the folding electric bicycle can be installed quickly without damaging the main frame, and it is characterized by stability, reliability, strong adaptability, convenient installation and lightweight.
[0038] Furthermore, the number of limiting screw holes 5 on the extension mounting bracket 2 is 2, and the corresponding hollow structure 9 is located between the two limiting screw holes 5. After the corresponding reinforcing screw 6 is installed, it is beneficial to enhance the stability between the two extension mounting brackets 2 after the hollow structure 9 is opened, thereby making the overall structure of the foot pedal device more stable.
[0039] Working Principle: The combination of the main mounting frame 1 and two extension mounting brackets 2 shifts the pedal mounting position from the traditional area under the seat to a position near the front wheel on the frame crossbeam. The main mounting frame 1 is bolted to the existing holes on the top of the frame crossbeam, and together with the extension mounting brackets 2, forms a clamping and fixing mechanism for the frame crossbeam. The mounting holes 4 of the extension mounting brackets 2 are used to insert double-ended screws 7, which secure the folding pedals at both ends, thus forming a stable front pedal support under the crossbeam. When the rider places their feet on the pedals, the pedaling force is transmitted through the pedals to the double-ended screws 7, then from the screws to the extension mounting brackets 2, and finally evenly distributed onto the frame crossbeam via the main mounting frame 1. The limiting screw holes 5 and reinforcing screws 6 provide additional lateral support, preventing the extension mounting brackets 2 from bulging outwards under stress. The perforated structure 9 not only reduces the weight of the device but also keeps the mounting area clean in rainy or dusty environments, preventing the accumulation of impurities. With this structural arrangement, the device can maintain a stable connection for a long time, thereby realizing the load-bearing function of the front foot pedal.
[0040] Installation process:
[0041] Positioning: Place the main mounting steel frame 1 on top of the crossbeam of the folding electric bicycle frame, aligning its fixing holes 3 with the original mounting holes 4 (such as water bottle holes) on the crossbeam.
[0042] Upper fixing: Place a shim 10 at the fixing hole 3, and thread a bolt through the fixing hole 3 to connect with the original hole of the frame beam to form the initial fixing of the top.
[0043] Lateral clamping: Bend the two extension mounting brackets 2 downwards so that they fit snugly against both sides of the frame crossbeam. By inserting reinforcing screws 6 through the limiting screw holes 5 above the mounting holes 4 and tightening the nuts, the two extension mounting brackets 2 form a stable lateral constraint under the crossbeam.
[0044] Foot pedal installation: Insert double-ended screws 7 into the mounting holes 4 at the acute angles of the bottom of the two extension mounting brackets 2, so that both ends extend beyond the outer surface of the mounting brackets. Screw the folding foot pedals onto both ends of the double-ended screws 7 and tighten them with the flange nuts to limit the extension length and ensure foot pedal balance.
[0045] Structural reinforcement: Check the tightness of the reinforcing bolts 6 and the flange nuts to ensure the bolts are securely connected to the steel frame. The openwork design allows for easy inspection of the installed components for water accumulation or foreign objects, facilitating cleaning.
[0046] Adaptive adjustment: If the thickness of the frame crossbeam is between 33mm and 38mm, it can be adaptively matched through the clamping spacing; the strip fixing hole 3 can be finely adjusted back and forth within a certain range to adjust the pedal installation position.
[0047] Storage check: Unfold and fold the foot pedals to confirm that they do not interfere with the folding action of the frame when folded, and to ensure that the overall storage function of the vehicle is normal.
[0048] By following the above installation steps, the device can be quickly fixed to the frame beam of a folding electric bicycle without welding or drilling modifications to the vehicle body, thus completing the installation of the front pedal.
[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
