Technical Field

[0001] This application relates to the field of self-balancing scooter technology, and in particular to a pedal assembly, a self-balancing scooter, and a method for manufacturing the pedal assembly. Background Technology

[0002] A self-balancing scooter is a new type of transportation. Unlike electric bicycles and motorcycles, which have wheels arranged front and back, self-balancing scooters use two wheels fixed side by side. By shifting the rider's center of gravity, the scooter can start, accelerate, decelerate, and stop.

[0003] In the process of developing this application, the inventors discovered that the pedals of a self-balancing scooter are primarily used to support the user's feet and to control the scooter's movement. Currently, a self-balancing scooter includes a frame, a mounting ring, and pedals. The frame has a receiving groove, within which the mounting ring and pedals are received. Furthermore, the mating mounting ring and the bottom of the receiving groove work together to press against the periphery of the pedals, thereby securing them in place. This structure requires the combined pressure of the mounting ring and the receiving groove to fix the pedals, making the installation process complex. Summary of the Invention

[0004] This application provides a pedal assembly that improves upon the technical problem of complex installation processes in current methods where the pedal is fixed by the joint compression between the mounting ring and the receiving groove.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a pedal assembly, including a footpad, an annular support frame, and a pedal body. The footpad defines a first mounting groove. The annular support frame is disposed in the outer region of the first mounting groove to provide support for the footpad. The pedal body is disposed in the inner region of the first mounting groove and is movably connected to the annular support frame through a connecting portion.

[0006] Optionally, the footpad has an anti-slip recess on the side facing the annular support frame, which prevents slipping when stepped on; or, the footpad has an anti-slip protrusion on the side away from the annular support frame, which prevents slipping when stepped on.

The first reinforcing portion strengthens the connection between the connecting portion body and the annular support frame, and the second reinforcing portion strengthens the connection between the connecting portion body and the pedal body.

[0010] Optionally, the annular support frame is provided with a groove and a reinforcing rib on the side away from the mat. The groove and the reinforcing rib are arranged along the annular frame of the annular support frame. The reinforcing rib is located in the middle of the groove and protrudes from one of the groove walls in the direction away from the mat.

[0011] Optionally, the annular support frame is further provided with a plurality of fixed columns, which are disposed in the groove, with one fixed column spaced apart from another.

[0012] Optionally, the pedal body is further provided with a trigger post and a trigger element. The trigger post extends from the pedal body in a direction away from the pedal pad. The trigger element is located in the middle of the trigger post and protrudes from the trigger post. The trigger element is used to trigger a switching device other than the pedal assembly. The trigger post is used to protect and support the trigger element.

[0013] Optionally, the outer edge of the foot pad is provided with a first inclined portion. The annular support frame has a second inclined portion adapted to the first inclined portion on its annular outer edge, and the first and second inclined portions are fixed by heat pressing.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a self-balancing scooter, including the above-mentioned pedal assembly and the self-balancing scooter body, wherein the self-balancing scooter body has a foot pedal platform recessed therein, and the pedal assembly is installed on the foot pedal platform.

[0015] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a pedal assembly, including a footpad, an annular support frame, and a pedal body. The footpad defines a first mounting groove. The annular support frame is disposed in the outer region of the first mounting groove to provide support for the footpad.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1 This illustration shows a perspective view of a self-balancing scooter 1000 according to one embodiment of this application. This application provides a self-balancing scooter 1000, including a pedal assembly 100 and a scooter body 200. A foot pedal platform 210 is recessed within the scooter body 200, and the pedal assembly 100 is mounted on the foot pedal platform 210. It is understood that the pedal assembly 100 is used for users to step on and control the movement of the scooter body 200.

[0030] For the pedal assembly 100 mentioned above, please refer to Figures 2 to 5The images show perspective views of a pedal assembly 100 provided in one embodiment of this application and a pedal assembly 100 provided in one embodiment of this application. Figure 2 The accompanying drawings include a cross-sectional view of side A, an exploded view of the pedal assembly 100 provided in one embodiment of this application, and another exploded view of the pedal assembly 100 provided in one embodiment of this application, in conjunction with other drawings. The pedal assembly 100 includes a foot pad 10, an annular support frame 20, and a pedal body 30. The foot pad 10 defines a first mounting groove 11. The annular support frame 20 is disposed in the outer region of the first mounting groove 11 to provide support for the foot pad 10. The pedal body 30 is disposed in the inner region of the first mounting groove 11 and is movably connected to the annular support frame 20 via a connecting portion 40. Specifically, the first mounting groove 11 defined by the foot pad 10 is formed in one step during the manufacturing process of the foot pad 10. The first mounting groove 11 is recessed towards the foot pad 10, and the side facing away from the first mounting groove 11 is used for user stepping. The first mounting groove 11 accommodates the annular support frame 20 and the pedal body 30. The outer area of ​​the first mounting groove 11 on which the annular support frame 20 is installed refers to the connection between the bottom and the wall of the first mounting groove 11, that is, the outer area is set along the edge of the foot pad 10, and the annular support frame 20 is set along the outer area and supports the foot pad 10. It can be understood that the annular support frame 20 can be a regular circular ring, elliptical ring, square ring or other irregular ring that matches the shape of the foot pad 10; in this embodiment, the foot pad 10 is set as a closed geometric shape with three straight edges and one semi-circular arc edge. Correspondingly, the annular support frame extends along the straight edges and the semi-circular arc edge and supports the foot pad 10. The part of the annular support frame away from the outer area of ​​the mounting groove is hollowed out, so as to facilitate the pedal body 30 to be received in the first mounting groove 11.

[0031] In this embodiment, please refer to Figure 3 and other accompanying drawings. The footpad 10 and the annular support frame 20 are integrally heat-pressed together, and the footpad 10 and the pedal body 30 are also integrally heat-pressed together. It should be noted that integral heat-pressing means that at the junction of the footpad 10 and the annular support frame 20, by changing process parameters such as temperature and pressure, the footpad 10 and the annular support frame 20 are fixed as a single unit, thus eliminating the need for fasteners or other fastening structures to secure the footpad 10 and the annular support frame 20. Similarly, at the junction of the footpad 10 and the pedal body 30, by changing process parameters such as temperature and pressure, the footpad 10 and the pedal body 30 are fixed as a single unit, thus eliminating the need for fasteners or other fastening structures to secure the footpad 10 and the pedal body 30. It is understood that the material of the footpad 10 includes, but is not limited to, TPU soft rubber (thermoplastic polyurethane rubber). This material mainly relies on intermolecular hydrogen bonding crosslinking or mild crosslinking between macromolecular chains. These two crosslinking structures are reversible as the temperature increases or decreases. In the molten or solution state, intermolecular forces weaken, but after cooling or solvent evaporation, strong intermolecular forces re-establish their bond, restoring the original solid properties. This facilitates the hot-pressing fixation between the pad 10 and the annular support frame 20, and between the pad 10 and the pedal body 30. It is worth noting that the materials of the annular support frame 20 and the pedal body 30 include, but are not limited to, ABS (acrylonitrile-butadiene-styrene copolymer). ABS utilizes its good bonding properties with other materials, and is easy to print, coat, and plate. Furthermore, ABS exhibits good mechanical properties and wear resistance. It is also worth mentioning that in the manufacturing process of the TPU and ABS materials used in this application, the annular support frame 20 and the pedal body 30 are first formed from ABS material using an injection molding process. Then, the formed annular support frame 20 and the pedal body 30 are placed in another injection molding machine, and the pad 10 is injection molded from TPU material and fixed by hot pressing. It is necessary to explain that the TPU and ABS materials used in this application have a high cost-performance ratio, facilitating cost control during product manufacturing.

[0032] For the aforementioned mat 10, please refer to Figure 4 and Figure 5 The following figures are also provided. The footpad 10 has an indentation 12 on the side facing the annular support frame 20 to prevent slippage when stepped on; alternatively, the footpad 10 has an indentation 12 on the side away from the annular support frame 20 to prevent slippage when stepped on. Specifically, the embodiment of this application uses the structure of the anti-slip recess 12. The anti-slip recess 12 extends along the surface of the footpad 10 in a radiating shape, thus facilitating the coverage of the footpad 10 surface. Part of the anti-slip recess 12 extends parallel to the straight edge of the footpad 10, and another part extends toward the arc-shaped outer edge of the footpad 10.

[0033] Further, please refer to Figure 4 and Figure 5 The annular support frame 20 is further provided with a first fixing groove 21, which is recessed in the surface of the annular support frame 20 facing the foot pad 10. The first fixing groove 21 is partially corresponding to the anti-slip recess 12, and the anti-slip recess 12 is partially received in the first fixing groove 21. The pedal body 30 is further provided with a second fixing groove 31, which is recessed in the surface of the pedal body 30 facing the foot pad 10. The second fixing groove 31 is partially corresponding to the other part of the anti-slip recess 12, and the anti-slip recess 12 is partially received in the second fixing groove 31. It can be understood that the anti-slip recess 12 on the foot pad 10 is recessed inward toward the side of the foot pad 10 where the first mounting groove 11 is provided. That is, a protrusion is provided in the first mounting groove 11, which is fixedly provided with the first fixing groove 21 and the second fixing groove 31. It can be understood that the anti-slip recess 12 is fixed by heat pressing to the first fixing groove 21 and the second fixing groove 31. By setting up this structure, the space in the first mounting groove 11 can be fully utilized, increasing the contact area between the foot pad 10 and the annular support frame 20, and between the foot pad 10 and the pedal body 30, thereby improving the bonding strength between the foot pad 10 and the annular support frame 20, and between the foot pad 10 and the pedal body 30.

[0034] Furthermore, please refer to Figure 6 It illustrates one embodiment of the present application. Figure 4 Enlarged view of part B. The outer edge of the foot pad 10 is provided with a first inclined portion 13. The outer edge of the annular support frame 20 is provided with a second inclined portion 25 that matches the first inclined portion 13. The first inclined portion 13 and the second inclined portion 25 are fixed by heat pressing. It can be understood that providing the first inclined portion 13 and the second inclined portion 25 increases the contact area between the foot pad 10 and the annular support frame 20, thereby improving the bonding strength between the foot pad 10 and the annular support frame 20 during heat pressing. On the other hand, the inclined edges of the foot pad 10 are more aesthetically pleasing, and according to ergonomic design, the foot pad 10 will not cause injury to the human body due to sharp edges.

[0035] In the embodiments of this application, please refer to Figure 4 and Figure 5The connecting portion 40 includes an integrally formed first reinforcing portion 41, a connecting portion body 42, and a second reinforcing portion 43. One end of the connecting portion body 42 is connected to the annular support frame 20, and the other end is connected to the pedal body 30. The first reinforcing portion 41 is disposed at the connection between the connecting portion body 42 and the annular support frame 20, and the second reinforcing portion 43 is disposed at the connection between the connecting portion body 42 and the pedal body 30. The first reinforcing portion 41 strengthens the connection between the connecting portion body 42 and the annular support frame 20, and the second reinforcing portion 43 strengthens the connection between the connecting portion body 42 and the pedal body 30. By providing the connecting portion 40, the annular support frame 20 and the pedal body 30 are connected. It is understood that the connecting portion 40 is also made of ABS material. It should be noted that the first reinforcing part 41 and the second reinforcing part 43 are provided to improve the connection strength between the connecting part body 42, the annular support frame 20, and the pedal body 30, preventing breakage. The width of the connecting part body 42 is smaller than that of the first reinforcing part 41 and the second reinforcing part 43 to facilitate bending deformation of the connecting part 40 and its return to its original position after bending deformation. It is understandable that, because the pedal body 30 will have a height difference relative to the annular support frame 20 when the user steps on the pedal 10, the TPU material used in the pedal 10 is a soft rubber material, which facilitates deformation.

[0036] For the aforementioned annular support frame 20, please refer to Figures 3 to 6 The annular support frame 20, on the side facing away from the foot pad 10, has a groove 22 and a reinforcing rib 23. The groove 22 and reinforcing rib 23 are arranged along the annular frame of the annular support frame 20. The reinforcing rib 23 is located in the middle of the groove 22, and protrudes from one of the groove walls towards the side facing away from the foot pad 10. It is understood that the reinforcing rib 23 can, on the one hand, improve the supporting strength of the annular support frame 20, increase the wall thickness of the annular support frame 20, save material usage, reduce the weight of the annular support frame 20, and prevent deformation of the annular support frame 20. On the other hand, it can help with material filling during the molding of the annular support frame 20, improving the flow of the ABS material during molding. It is understood that in some other embodiments, the strength and rigidity of the annular support frame 20 can be improved without increasing the wall thickness by increasing the number of reinforcing ribs 23. It is understood that the reinforcing rib 23 in the embodiments of this application extends along the contour of the annular support frame 20, thereby balancing the stress distribution of the annular support frame 20.

[0037] Further, please refer to Figures 3 to 6The annular support frame 20 is also provided with a plurality of fixing posts 24, which are disposed within the grooves 22, with one fixing post 24 spaced apart from another. The fixing posts 24 serve to support the annular support frame 20, and can also have threaded holes or other fixing structures provided on them, thereby facilitating the fixing of the annular support frame 20 to structures other than the pedal assembly 100.

[0038] Please refer to the figure and other accompanying drawings for the pedal body 30 described above. The pedal body 30 is also provided with a trigger post 32 and a trigger element 33. The trigger post 32 extends from the pedal body 30 in a direction away from the pedal pad 10. The trigger element 33 is disposed in the middle of the trigger post 32 and protrudes from the trigger post 32. The trigger element 33 is used to trigger a switching device other than the pedal assembly 100. The trigger post 32 is used to protect and support the trigger element 33.

[0039] In other embodiments of this application, the pedal assembly 100 includes a foot pad 10, a support frame, and a pedal body 30. The foot pad 10 defines a first mounting groove 11. The support frame is disposed in the outer region of the first mounting groove 11 to provide support for the foot pad 10. The pedal body 30 is disposed in the inner region of the first mounting groove 11 and is movably connected to the support frame via a connecting portion 40. It should be noted that the support frame can be a regular circular, elliptical, square, or other irregular shape that matches the shape of the foot pad 10, and the support frame can be configured as a closed or open support structure depending on the actual stress conditions.

[0040] In conjunction with the above embodiments, the manufacturing method of the foot pad 10 is further described: the pedal assembly 100 includes: a foot pad 10, an annular support frame 20, and a pedal body 30.
