Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically to a pedal device with a cushioning and anti-collision structure. Background Technology

[0002] Traditional bicycle or electric bicycle pedals are typically made of rigid materials and directly fixed to the cranks. During riding, if the bicycle tips over or is parked against a wall, the pedals are prone to colliding with hard objects such as the ground or walls, resulting in surface scratches, deformation, and even damage to the internal structure, affecting the appearance and lifespan. While some existing technologies mitigate impact by adding cushioning pads, these designs often have poor durability and are difficult to actively avoid and quickly return to their original position upon collision.

[0003] Therefore, there is an urgent need to improve the existing foot pedal mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a foot pedal device with a cushioning and anti-collision structure. The added cushioning structure solves the problem of traditional foot pedal devices being easily damaged in appearance and internal structure due to rigid impacts when tipping over or against a wall. Therefore, it reduces the frequency of foot pedal replacement due to damage and lowers usage costs. The implementation of this technical solution is as follows:

[0005] A foot pedal device with a cushioning and anti-collision structure includes: an outer pedal, an inner pedal, an elastic element, and a shaft core; the inner pedal is disposed inside the outer pedal and is slidably connected to the outer pedal; the two ends of the elastic element abut against the outer pedal and the inner pedal respectively; the shaft core is partially sleeved in the inner pedal and is used for fixed connection with a crank.

[0006] Preferably, it further includes a flexible sleeve, which is disposed between the outer pedal and the inner pedal and sleeved on the outside of the elastic member.

[0007] Preferably, the elastic element is a spring.

[0008] Preferably, a guide block is provided on the inner side of the outer pedal, and a guide groove is provided on the outer side of the inner pedal. The guide block and the guide groove cooperate to achieve relative sliding between the outer pedal and the inner pedal.

[0009] Preferably, it also includes a locking bar, with locking holes provided at both ends of the inner pedal, the locking bar passing through the locking holes, and the guide block being provided with a locking groove, on which the locking bar can move.

[0010] Preferably, the outer pedal is further provided with a positioning hole, and the elastic element is sleeved in the positioning hole.

[0011] Preferably, it also includes reflective strips, and strip grooves are provided on both sides of the outer pedal, with the reflective strips installed in the strip grooves.

[0012] Preferably, the outer pedal and the inner pedal are provided with a plurality of anti-slip strips on their end faces, and the plurality of anti-slip strips are respectively laid on the end faces of the outer pedal and the inner pedal.

[0013] Compared with the prior art, this application has the following advantages:

[0014] (1) In this technical solution, the inner pedal is slidably connected to the outer pedal, and the two ends of the elastic element abut against the outer pedal and the inner pedal respectively. When the foot pedal device is subjected to an external force, the external force causes the outer pedal to move towards the inner pedal, thereby compressing the elastic element and converting the impact energy into elastic potential energy. After the external force disappears, the elastic element pushes the outer pedal to return to its original position. By setting the elastic element, the impact energy can be effectively absorbed when subjected to an external force, reducing the risk of damage to the foot pedal device and improving the durability of the foot pedal device.

[0015] (2) In this technical solution, guide blocks and guide grooves are respectively provided on the inner side of the outer pedal and the outer side of the inner pedal to form a sliding pair to prevent the outer pedal from deviating or getting stuck when sliding; the locking bar is inserted into the locking hole of the inner pedal and cooperates with the locking groove of the guide block to limit the sliding range; the cooperation between the guide block and the guide groove and the cooperation between the locking bar and the locking groove ensure the stability and reliability of the relative sliding of the outer pedal and the inner pedal, avoid excessive displacement or separation, and ensure the integrity of the foot pedal structure.

[0016] (3) All components of this technical solution, including the outer pedal, inner pedal, elastic element, shaft core, flexible sleeve, locking bar and reflective strip, can be modularized. When some parts are damaged or reach the end of their service life, they can be directly replaced, reducing cost expenditure. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Embodiments of this application provide a foot pedal device with a cushioning and anti-collision structure, such as Figure 1-7 As shown, the foot pedal device includes an outer pedal 1, an inner pedal 2, an elastic element 3, and a shaft core 4; the inner pedal 2 is slidably connected to the outer pedal 1; the two ends of the elastic element 3 abut against the outer pedal 1 and the inner pedal 2 respectively; the shaft core 4 is partially sleeved in the inner pedal 2, and the shaft core 4 is used for fixed connection with the crank.

[0038] To better understand some implementation methods of this application, such as Figure 6 As shown, one application scenario of the foot pedal device with a cushioning and anti-collision structure protected by this application is as follows: When the foot pedal device is impacted by an external force (such as tipping over or hitting a wall), the external force acts on the outer pedal 1, forcing it to move towards the inner pedal 2; at this time, the elastic element 3 is compressed, converting the impact energy into elastic potential energy. After the external force disappears, the elastic element 3 pushes the outer pedal 1 to reset, restoring the foot pedal device to its initial position and avoiding damage caused by rigid collision.

[0039] The above describes the application scenarios of the foot pedal device of this application to facilitate understanding of the purpose of this application. It can also be used in other scenarios, which will not be elaborated here.

[0040] In some implementations, such as Figure 2 As shown, the elastic element 3 is a spring. When an external force is applied to the outer pedal 1 to move towards the inner pedal 2, the elastic element 3 actively absorbs energy and avoids impact during the collision, significantly reducing the risk of damage to the foot pedal device.

[0041] In some implementations, such as Figure 1 and Figure 7As shown, it also includes a flexible sleeve 5, which is disposed between the outer pedal 1 and the inner pedal 2 and sleeved on the outside of the elastic member 3; the flexible sleeve 5 is a plastic sleeve or a silicone sleeve; preferably, the flexible sleeve 5 can be made of weather-resistant TPU material; when an external force is applied to the outer pedal 1 to move towards the inner pedal 2, the elastic member 3 actively absorbs energy and avoids the impact during the collision, while the flexible sleeve 5 further absorbs the residual impact, improving the overall impact resistance performance; furthermore, the flexible sleeve 5 can also protect the elastic member 3 from environmental corrosion.

[0042] In some implementations, such as Figure 3-5 As shown, guide blocks 12 are provided at both ends of the inner side of the outer pedal 1, and guide grooves 21 are provided at both ends of the outer side of the inner pedal 2. The guide blocks 12 and the guide grooves 21 cooperate to realize the relative sliding of the outer pedal 1 and the inner pedal 2. Specifically, when an external force is applied to the outer pedal 1, the guide blocks 12 of the outer pedal 1 and the guide grooves 21 of the inner pedal 2 slide relative to each other. The guide blocks 12 and the guide grooves 21 form a sliding pair to prevent the outer pedal 1 from deviating or getting stuck when sliding.

[0043] In some implementations, such as Figure 3-5 As shown, it also includes a locking bar 6. The inner pedal 2 has locking holes 22 at both ends. The locking holes 22 are through holes. The locking bar 6 is inserted through the locking holes 22. The guide block 12 is provided with a locking groove 121. The locking bar 6 can move on the locking groove 121. Specifically, during assembly, the locking bar 6 cooperates with the locking groove 121 to limit the sliding range and prevent the outer pedal 1 and the inner pedal 2 from sliding excessively or disengaging.

[0044] In some implementations, such as Figure 2-3 As shown, the outer pedal 1 is also provided with a positioning hole 11, which is a blind hole. The elastic element 3 is partially sleeved in the positioning hole 11, and the flexible sleeve 5 is also partially sleeved in the positioning hole 11. Specifically, the positioning hole 11 ensures that the installation positions of the elastic element 3 and the flexible sleeve 5 are accurate, and avoids the elastic element 3 and the flexible sleeve 5 from shifting when subjected to external force.

[0045] In some implementations, such as Figure 2-3 As shown, it also includes a reflective strip 7. The outer pedal 1 has strip grooves 13 on both sides, and the reflective strip 7 is installed in the strip grooves 13. The reflective strip 7 improves visibility at night or in low light conditions, enhances riding safety, and improves practicality and safety.

[0046] In some implementations, such as Figure 1-2As shown, a plurality of anti-slip strips 8 are provided on both ends of the outer pedal 1 and the inner pedal 2, and the plurality of anti-slip strips 8 are respectively laid on the end surfaces of the outer pedal 1 and the inner pedal 2; specifically, the anti-slip strips 8 are made of wear-resistant rubber material, which extends the service life of the anti-slip strips 8; when riding a bicycle, the anti-slip strips 8 can increase the friction between the sole of the shoe and the pedal device, and prevent slipping while riding.

[0047] The components of this embodiment—outer pedal 1, inner pedal 2, elastic element 3, shaft core 4, flexible sleeve 5, locking bar 6, and reflective strip 7—can all be modularized. When the outer pedal is damaged by irreversible forces, the outer pedal 1 can be directly replaced. When the elastic element 3 or flexible sleeve 5 reaches the end of its service life, the elastic element 3 or flexible sleeve 5 can also be directly replaced, thereby reducing cost expenditure.

[0048] The working principle of the foot pedal device with a cushioning and anti-collision structure in this embodiment is as follows:

[0049] In this technical solution, the outer pedal 1 and the inner pedal 2 are slidably connected, and the two ends of the elastic element 3 abut against the outer pedal 1 and the inner pedal 2 respectively. When the foot pedal device is subjected to an external force, the external force causes the outer pedal 1 to move towards the inner pedal 2, thereby compressing the elastic element 3 and converting the impact energy into elastic potential energy. After the external force disappears, the elastic element 3 pushes the outer pedal 1 to return to its original position. At the same time, guide blocks 12 and guide grooves 21 are respectively provided on the inner side of the outer pedal 1 and the outer side of the inner pedal 2 to form a sliding pair, preventing the outer pedal 1 from deviating or getting stuck when sliding. The locking bar 6 is inserted into the locking hole 22 of the inner pedal 2 and cooperates with the locking groove 121 of the guide block 12 to limit the relative sliding range of the outer pedal 1 and the inner pedal 2.

[0050] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
