Description

Technical Field

[0001] The utility model relates to the field of bicycles, and particularly relates to a bicycle pedal. Background Art

[0002] Most of the existing bicycle pedal structures adopt a simple rotational connection method, usually consisting of a pedal body and a fixed shaft, and the pedal body can rotate freely around the fixed shaft. Although such traditional pedal structures can meet the basic riding needs, there are some obvious deficiencies.

[0003] Firstly, the labor-saving performance of traditional pedals is insufficient. The total length torque of existing pedals is generally small, usually about 175 mm, which will cause greater pedaling resistance during riding. Especially during long rides or climbing, riders need to consume more physical strength, and the riding comfort is poor, making people prone to fatigue.

[0004] Secondly, the balance of the pedals is poor. When no external force is applied, existing pedals are prone to tilt or rotate, resulting in the pedals not being able to maintain a horizontal state. This requires riders to manually adjust the pedal angle when pedaling again, affecting the smoothness of riding and increasing the complexity of operation.

[0005] In addition, existing pedals lack effective limiting measures. In traditional pedal structures, the pedal body can rotate freely and lacks a limiting function in terms of direction. Especially, it is impossible to effectively distinguish between the force application direction and the rotation direction, resulting in low transmission efficiency of the pedals during riding, unable to make full use of the pedaling force of riders, and affecting the riding efficiency. Summary of the Utility Model

[0006] In order to solve the above problems, the utility model provides a bicycle pedal, which can solve the above problems and improve the labor-saving performance, balance and use stability of riding.

[0007] The utility model is realized through the following technical solutions: A bicycle pedal includes a pedal body, and the pedal body includes at least one main part and at least one extension part;

[0008] A fixed shaft, which is fixedly connected to the frame body, and the pedal body is rotatably installed on the fixed shaft;

[0009] A connecting bushing is arranged on one side of the pedal body, and the pedal body is rotatably connected to the fixed shaft through the connecting bushing;

[0010] The distance between the extension part and the fixed shaft forms a moment L1, and the distance between the main part and the fixed shaft forms a moment L2. The balance of the entire pedal body relative to the horizontal plane is maintained through the moment ratio between the moment L1 and the moment L2 and the extension part;

[0011] A one-way bearing is installed between the fixed shaft and the connecting bushing, and the one-way bearing is used to limit the pedal body in the force application direction.

[0012] As a preferred technical solution, one end of the connecting bushing has a connecting section, and the connecting bushing is connected to the main body through the connecting section. The connecting bushing, the connecting section and the pedal body are arranged side by side.

[0013] As a preferred technical solution, an elastic clearance cavity is formed between the lower end surface of the pedal body and the fixed shaft. When a force is applied to the pedal body, the pedal body elastically deforms in a direction away from the fixed shaft.

[0014] As a preferred technical solution, an arc-shaped concave surface is formed on the upper surfaces of the extension part and the main body part, and the extension section of the fixed shaft is located in the arc-shaped concave surface and does not contact the fixed shaft during pedaling.

[0015] As a preferred technical solution, an extension tip is provided on the main body part of the pedal body.

[0016] As a preferred technical solution, a support bearing is further included. The support bearing is installed on one side of the one-way bearing, and the support bearing is installed on the fixed shaft, and both the support bearing and the one-way bearing are located inside the connecting bushing.

[0017] As a preferred technical solution, a plurality of hollow holes are provided on the pedal body.

[0018] As a preferred technical solution, the distance length of the moment L2 is greater than the distance length of the moment L1.

[0019] The beneficial effects of the present utility model are as follows: By providing an extension part, the pedal body forms two moment segments relative to the fixed shaft. Through a reasonable moment ratio setting, during the actual pedaling process, the total length moment of the pedal increases from 175 mm of the traditional pedal to 255 - 265 mm. This increase in moment can significantly reduce the pedaling resistance of the rider, making it more labor-saving when riding, reducing physical consumption, and improving the riding comfort;

[0020] Moreover, the setting of the extension part enables the pedal body to maintain a balanced state relative to the horizontal plane when no external force is applied, which helps the pedal not to tilt and maintain a horizontal position when pedaling stops. The rider does not need to adjust the pedal angle when pedaling again, facilitating the riding operation and improving the riding experience;

[0021] Moreover, by arranging a one-way bearing between the fixed shaft and the connecting shaft sleeve, the present utility model enables the pedal body to be limited in the force application direction, that is, the pedal can only move in the force application direction (such as the clockwise direction) during cycling, avoiding the rotation of the pedal in unnecessary directions, thereby improving the transmission efficiency of the pedal. In addition, the one-way bearing also ensures that the pedal can rotate normally in the reverse direction after the force is applied, maintaining the smoothness of cycling;

[0022] In addition, the present utility model arranges a support bearing on one side of the one-way bearing, further enhancing the support stability of the pedal body. The support bearing and the one-way bearing work together to ensure the stability of the pedal during use, avoiding the situation of shaking or instability of the pedal during high-intensity use and extending the service life of the pedal.

[0030] All the features disclosed in this specification, or all the steps in any method or process disclosed, except for mutually exclusive features and / or steps, can be combined in any way.

[0031] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or features with similar purposes. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0032] As shown Figures 1 - 3 in the figure, a bicycle pedal of the present utility model includes a pedal main body, and the pedal main body includes at least one main part 1 and at least one extension part 2;

[0033] It further includes a fixed shaft 3, the fixed shaft 3 is fixedly connected to the frame main body, and the pedal main body is rotatably installed on the fixed shaft 3;

[0034] It further includes a connecting bushing 4, which is arranged on one side of the pedal main body, and the pedal main body is rotatably connected to the fixed shaft 3 through the connecting bushing 4, and a locking screw is arranged on one side of the fixed shaft 3;

[0035] Wherein, the distance between the extension part 2 and the fixed shaft 3 forms a moment L1, and the distance between the main part 1 and the fixed shaft 3 forms a moment L2. The balance of the entire pedal main body relative to the horizontal plane is maintained through the moment ratio between the moment L1 and the moment L2 and the extension part 2;

[0036] Assume that the total length of the traditional moment is 175mm, and the moment change of the present utility model is 175+(80mm to 90mm), so the moment change is from 255m to 265mm in total length.

[0037] As Figure 3 shown, assume that the pressure on the extension part 2 is F1 and the pressure on the main part 1 is F2. The purpose of F1 is to adjust and maintain the level of the pedal; due to the overall increase in the moment, the force application of F2 can be more labor-saving, achieving the purpose of easy work.

[0038] It further includes a one-way bearing 6, which is installed between the fixed shaft 3 and the connecting bushing 4. The one-way bearing 6 is used to limit the position of the pedal main body in the force application direction. In this embodiment, it cannot rotate normally when rotating clockwise, so pressure can be applied to the entire pedal main body, and the counterclockwise direction is the normal rotation direction to achieve normal rotation.

[0039] As Figure 1 and Figure 2 shown, one end of the connecting bushing 4 has a connecting section 5, the connecting bushing 4 is connected to the main part 1 through the connecting section 5, and the connecting bushing 4, the connecting section 5 and the pedal main body are arranged side by side. Due to the arrangement of the connecting section 5 and the connecting bushing 4, the bottom of the pedal main body does not actually contact the fixed shaft 3, and the structural design is more reasonable. The force applied to the pedal main body will not directly act on the fixed shaft 3, and the service life is longer. Moreover, the structure of the present utility model can effectively reduce the pressure of external force on the fixed shaft 3. This kind of pressure generally acts on the main part 1 and does not directly act on the fixed shaft 3, which can effectively improve the service life and stability of the fixed shaft 3.

[0040] Among them, as Figure 3 shown, an arc-shaped concave surface is formed on the upper surface of the extension part 2 and the main body part 1. The extension section of the fixed shaft 3 is located within the arc-shaped concave surface and does not contact the fixed shaft during pedaling. When in use, the position of the human foot contacts the extension part and the main body part and does not contact the fixed shaft. In this way, when pedaling, the entire pedal body moves away from the fixed shaft, achieving the purpose of force avoidance. The human foot does not contact the fixed shaft, and the force is more reasonable, making the service life of the fixed shaft longer.

[0041] As Figure 4 shown, an extension tip 8 is provided on the main body part 1 of the pedal body. By means of the extension tip 8, the matching degree with the foot is increased, further improving the contact area with the foot, while not causing excessive increase in materials.

[0042] Among them, the connecting section 5 and the entire pedal body are in an arch shape. Therefore, there are two contact points during pedaling, namely the toe position and the heel position. The toe position contacts the extension tip position of the main body part, and the heel position contacts the extension part. The bottom of the sole is hollowed out to accommodate the fixed shaft. The arch structure has high force-bearing strength, is more in line with ergonomics, and is convenient for cycling.

[0043] As Figure 2 shown, it further includes a support bearing 7. The support bearing 7 is installed on one side of the one-way bearing 6, and the support bearing 7 is installed on the fixed shaft 3. Both the support bearing 7 and the one-way bearing 6 are located within the connecting shaft sleeve 4. By means of the cooperation of the support bearing 7 and the one-way bearing 6, the entire pedal body can be more stable during use.

[0044] Among them, a plurality of hollow holes are provided on the pedal body to reduce the overall weight of the entire pedal while ensuring the overall strength.

[0045] By providing the extension part 2 in the present utility model, the pedal body forms two moment segments relative to the fixed shaft 3. Through reasonable setting of the moment ratio, during the actual pedaling process, the total length moment of the pedal increases from 175 mm of the traditional pedal to 255 - 265 mm. This increase in moment can significantly reduce the pedaling resistance of the cyclist, making cycling more labor-saving, reducing physical consumption, and improving the comfort of cycling;

[0046] Moreover, the setting of the extension part 2 enables the pedal body to maintain a balanced state relative to the horizontal plane without applying external force, which helps the pedal not to tilt and maintain a horizontal position when pedaling stops. The cyclist does not need to adjust the pedal angle when pedaling again, facilitating the cycling operation and improving the cycling experience;

[0047] Moreover, in the present utility model, a one-way bearing 6 is provided between the fixed shaft 3 and the connecting shaft sleeve 4, so that the pedal body can be limited in the force application direction, that is, the pedal can only move in the force application direction (such as the clockwise direction) during riding, avoiding the rotation of the pedal in unnecessary directions, thereby improving the transmission efficiency of the pedal. In addition, the one-way bearing 6 also ensures that the pedal can rotate normally in the reverse direction after the force is applied, maintaining the smoothness of riding;

[0048] In addition, a support bearing is provided on one side of the one-way bearing in the present utility model, further enhancing the support stability of the pedal body. The support bearing and the one-way bearing work together to ensure the stability of the pedal during use, avoiding the shaking or instability of the pedal during high-intensity use, and extending the service life of the pedal;

[0049] An elastic clearance cavity is formed between the lower end surface of the pedal body and the fixed shaft. When a force is applied to the pedal body, the pedal body can undergo elastic deformation in the direction towards the fixed shaft. If the force during standing riding is too large, the elastic deformation of the pedal tail will transmit the force to the long shaft, thereby providing a certain buffering effect. The force-bearing structure is more reasonable, reducing the impact force on the pedal and the foot during riding, further improving the riding comfort and having higher safety;

[0050] The overall arch-shaped design of the pedal body and the connecting section makes the pedal more beautiful in structure. By forming an arched convex surface on the upper surface and an arc-shaped concave surface on the lower surface of the pedal, not only the appearance design sense of the pedal is improved, but also the force-bearing structure of the pedal is optimized, improving the use performance and strength of the pedal. In addition, a plurality of hollow holes provided on the pedal body reduce the weight of the pedal, further enhancing the portability of riding.

[0051] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative labor should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
