Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an electric scooter. Background Technology

[0002] Electric scooters were originally designed for short-distance travel by single riders. However, in many areas today, multiple people are riding a single electric scooter, and this overloading significantly increases safety risks and the likelihood of traffic accidents.

[0003] Therefore, not only are the laws and regulations of local governments required, but the electric scooters themselves also need to be able to identify and control multiple riders. By detecting the actual number of people riding on an electric scooter, it is helpful to limit the situation where multiple people ride on one electric scooter. Utility Model Content

[0004] To address the aforementioned problems, embodiments of this application provide an electric scooter that at least partially solves these problems.

[0005] The electric scooter provided in this application includes:

[0006] Frame,

[0007] The pedals, mounted on top of the frame, are used to support the rider's weight.

[0008] A cover plate has a first groove on the upper surface of the pedal and / or a second groove on the lower surface of the cover plate. The cover plate and the upper surface of the pedal are connected, and when connected, the first groove and / or the second groove form a receiving cavity between the cover plate and the pedal.

[0009] The sensor assembly includes a plurality of pressure sensors spaced apart on the upper surface of the pedal, the plurality of pressure sensors being fixed in the receiving cavity.

[0010] Optionally, the cover plate includes a main body and multiple sets of protrusions. The number of multiple pressure sensors and the number of multiple sets of protrusions are the same and correspond one-to-one. Each set of protrusions includes at least one upper protrusion and at least one lower protrusion. The main body is constructed as a plate-like structure and has multiple spaced clearance holes. The number of clearance holes, lower protrusions, and upper protrusions are the same and correspond one-to-one. The lower protrusion is located below the upper protrusion. The outer periphery of the lower protrusion is connected to the inner wall of the clearance hole, and the inner side of the lower protrusion is connected to the upper protrusion. In the vertical direction, the upper end of the upper protrusion protrudes beyond the upper surface of the main body, and the lower end of the lower protrusion protrudes beyond or is flush with the lower surface of the main body.

[0011] Optionally, the upper protrusion is constructed as a cylindrical member with an open lower end; the lower protrusion includes an inner annular plate and an outer annular plate distributed radially along the clearance hole, both the inner annular plate and the outer annular plate extending obliquely from top to bottom, the upper end of the outer annular plate being connected to the inner wall surface of the clearance hole, the lower end of the outer annular plate being connected to the lower end of the inner annular plate, and the upper end of the inner annular plate being connected to the opening edge of the upper protrusion.

[0012] Optionally, the sensor assembly further includes at least one connector, through which adjacent pressure sensors are connected together; the first groove includes multiple receiving areas and at least one connecting area, the receiving areas and the connecting areas are alternately distributed, the multiple pressure sensors are located in the multiple receiving areas one by one, and the at least one connector is located in the at least one connecting area one by one; the pedal further includes a limiting protrusion disposed between adjacent receiving areas, the limiting protrusion being spaced between adjacent pressure sensors.

[0013] Optionally, the pedal further includes a first connecting hole and a dam located around the first groove, with the first connecting hole provided on both the limiting protrusion and the dam; the cover plate is provided with a second connecting hole, and the electric scooter further includes a connecting fastener, which passes through the second connecting hole and is connected to the first connecting hole.

[0014] Optionally, the electric scooter further includes a power supply; the frame includes a first receiving groove in which the power supply is housed; when the pedal is connected to the frame, it covers the opening of the first receiving groove; the pedal is also provided with a second receiving groove and a through hole, the through hole being located on the inner wall of the second receiving groove; when the cover plate is connected to the pedal, it covers the opening of the second receiving groove; the sensor assembly further includes an electronic control module and a conductive wire; each pressure sensor is electrically connected to the electronic control module; one end of the conductive wire is connected to the electronic control module, and the other end passes through the through hole and extends into the first receiving groove; the conductive wire is electrically connected to the power supply.

[0015] Optionally, the electric scooter further includes a master controller and a master control lead, one end of which is connected to the master controller and the other end is located in the first receiving slot; the sensor assembly further includes a signal line, one end of which is connected to the electronic control module and the other end of which passes through the through hole into the first receiving slot and is connected to the master control lead.

[0016] Optionally, the electronic control module and the plurality of pressure sensors are integrally coated with adhesive.

[0019] Based on the electric scooter provided in this application, by mounting the pedals on the frame, the pedals and frame can jointly support the rider's weight. When the rider steps on the cover, the pressure sensor directly opposite the foot experiences greater pressure and is thus triggered, while pressure sensors not directly under the foot experience little or no pressure and are not triggered. Based on the size of the rider's foot, the distribution of the pressure sensors, and the number of triggered sensors, the number of feet stepping on the cover can be determined, thus indicating the actual number of riders. Furthermore, directly fixing the pressure sensors in the cavity between the cover and the pedals not only limits their movement but also allows the cover to cover them. When riding the electric scooter, the rider's foot steps on the cover, and the cover transfers the rider's weight to the pressure sensors. This not only avoids the problem of direct foot pressure damaging the sensors but also provides waterproofing and dustproofing, further reducing the probability of sensor damage. Therefore, in this technical solution, the cover plate can not only be used to fix and install the pressure sensor, but also protect the pressure sensor. The electric sliding plate has a simple structure and good protection performance for the pressure sensor. Attached Figure Description

[0034] To provide a clearer understanding of the technical features, objectives, and effects of the embodiments of this application, the specific implementation methods of the embodiments of this application will now be described with reference to the accompanying drawings.

[0035] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0036] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown as one or more, or only one or more are labeled.

[0037] This application provides an electric scooter, as shown in the reference. Figure 1The electric scooter includes a frame 10, a pedal 20, a cover plate 30, and a sensor assembly 40. The pedal 20 is mounted above the frame 10 and serves to support the rider's weight. A first groove 21 is provided on the upper surface of the pedal 20, and / or a second groove is provided on the lower surface of the cover plate 30. The upper surfaces of the cover plate 30 and the pedal 20 are connected, and when connected, the first groove 21 and / or the second groove form a receiving cavity between the cover plate 30 and the pedal 20. The sensor assembly 40 includes a plurality of pressure sensors 41 spaced apart on the upper surface of the pedal 20, and the plurality of pressure sensors 41 are fixed in the receiving cavity.

[0038] Based on the above technical solution, by mounting the pedal 20 on the frame 10, the pedal 20 and the frame 10 can jointly support the rider's weight. Specifically, when a rider steps on the cover plate 30, the pressure sensor 41 directly opposite the foot experiences greater pressure and is thus triggered, while pressure sensors 41 not directly under the foot experience little or no pressure and are not triggered. Based on the size of a person's foot, the distribution of the pressure sensors 41, and the number of triggered pressure sensors 41, it is possible to determine how many feet are stepping on the cover plate 30, and thus the actual number of riders. Furthermore, directly fixing the pressure sensor 41 within the cavity between the cover plate 30 and the pedal 20 not only limits the movement of the pressure sensor 41 but also allows the cover plate 30 to cover the pressure sensor 41. When riding the electric scooter, the rider's foot rests on the cover plate 30, which transfers the rider's weight to the pressure sensor 41. This not only avoids the problem of the pressure sensor 41 being easily damaged by direct foot pressure but also provides waterproofing and dustproofing, further reducing the probability of damage to the pressure sensor 41. Therefore, in this technical solution, the cover plate 30 not only securely mounts the pressure sensor 41 but also protects it. The electric scooter has a simple structure and provides good protection for the pressure sensor 41.

[0039] It should be clarified that the terms "upper" and "lower" in this application refer to the distribution of various components in the electric scooter in the direction of gravity when riding the scooter on a road. For example, during actual riding, the cover plate 30 is located above the pedal 20, the surface of the cover plate 30 facing the pedal 20 is the lower surface of the cover plate 30, and the surface of the cover plate 30 away from the pedal 20 is the upper surface. Additionally, the second groove is not shown in the accompanying drawings.

[0040] The cover plate 30 can be made of stainless steel. Stainless steel has high strength and corrosion resistance, effectively resisting impacts and wear that may occur during riding, ensuring the durability and stability of the cover plate 30. In addition, stainless steel also has good waterproof properties, keeping the inside of the cover plate 30 dry in humid environments, further extending the service life of the pressure sensor 41.

[0041] In one possible implementation, the pressure sensor 41 is bonded to the upper surface of the pedal 20. Further, the pressure sensor 41 is bonded to the bottom surface of the first groove 21.

[0042] In one possible implementation, refer to Figure 2 and Figure 3 In one possible implementation, the cover plate 30 includes a main body 31 and multiple sets of protrusions. The number of multiple pressure sensors 41 and the multiple sets of protrusions are the same and correspond one-to-one. Each set of protrusions includes at least one upper protrusion 32 and at least one lower protrusion 33. The main body 31 is constructed as a plate structure and has multiple spaced clearance holes. The number of clearance holes, lower protrusions 33 and upper protrusions 32 are the same and correspond one-to-one. The lower protrusion 33 is located below the upper protrusion 32. The outer periphery of the lower protrusion 33 is connected to the inner wall of the clearance hole, and the inner side of the lower protrusion 33 is connected to the upper protrusion 32. In the vertical direction, the upper end of the upper protrusion 32 protrudes from the upper surface of the main body 31, and the lower end of the lower protrusion 33 protrudes from or is flush with the lower surface of the main body 31. Alternatively, it can be understood that the orthographic projections of the upper protrusion 32 and the lower protrusion 33 on the pedal 20 both fall within the orthographic projection range of the pressure sensor 41 on the pedal 20, and within the orthographic projection range of each pressure sensor 41, there is at least one orthographic projection of the upper protrusion 32 and the lower protrusion 33.

[0043] Based on the above technical solution, since the number of pressure sensors 41 and the number of protrusions are the same and correspond one-to-one, a set of protrusions is provided on the cover plate 30 at the position corresponding to each pressure sensor 41. During cycling, the upper end of the upper protrusion 32 is higher than the upper surface of the main body 31 in the vertical direction. The upper protrusion 32 and the pressure sensor 41 are directly corresponding. Whenever a cyclist steps on an upper protrusion 32, the corresponding lower protrusion 33 will move downwards and directly press against the upper surface of the pressure sensor 41. With this design, when the upper protrusion 32 is pressed by the cyclist, it will push the lower protrusion 33 downwards to press against the pressure sensor 41. When the pressure on the pressure sensor 41 meets the preset conditions, it can be determined that the pressure sensor 41 has been triggered. Therefore, the number of feet simultaneously pressing on the cover plate 30 can be determined based on the number of triggered pressure sensors 41. Furthermore, by setting the upper protrusion 32, the roughness of the upper surface of the cover plate 30 can be increased, achieving an anti-slip effect.

[0044] In one possible embodiment, reference Figure 3 The upper protrusion 32 is a cylindrical member with an open lower end; the lower protrusion 33 includes an inner annular plate 331 and an outer annular plate 332 radially distributed along the clearance hole. Both the inner annular plate 331 and the outer annular plate 332 extend obliquely from top to bottom. The upper end of the outer annular plate 332 is connected to the inner wall of the clearance hole, and the lower end of the outer annular plate 332 is connected to the lower end of the inner annular plate 331. The upper end of the inner annular plate 331 is connected to the opening edge of the upper protrusion 32. Based on this technical solution, the lower protrusion 33 is a plate-shaped member with a V-shaped cross-section, thus the lower protrusion 33 has a certain degree of flexibility and can undergo small-amplitude elastic deformation. The upper protrusion 32 is connected to the main body 31 through the lower protrusion 33. When the upper protrusion 32 is stepped on downward, the upper protrusion 32 will drive the lower protrusion 33 to move slightly downward relative to the main body 31, thereby pressing downward against the pressure sensor 41. Moreover, since the upper protrusion 32 is a cylindrical component and the lower protrusion 33 is a plate-shaped component with a V-shaped cross-section, both the upper protrusion 32 and the lower protrusion 33 are hollow components, which are relatively lightweight and help to reduce the weight of the cover plate 30 and facilitate the installation of the cover plate 30.

[0045] In one possible embodiment, the main body 31, the lower protrusion 33, and the upper protrusion 32 can be connected together by welding or by integral stamping. A material with good ductility can be selected for integral stamping of the cover plate 30.

[0046] Furthermore, those skilled in the art should understand that the distribution range of the upper protrusion 32 in each group of protrusions can be as close as possible to the distribution range of the pressure sensor 41, that is, the orthographic projection range of a pressure sensor 41 should be filled as much as possible by the orthographic projection of the upper protrusion 32, so that each pressure sensor 41 can be pressed against by the lower protrusion 33 in the corresponding group of protrusions. This not only helps to increase the anti-slip effect of the upper surface of the cover plate 30, but also helps to balance the force on the pressure sensor 41. Furthermore, the total distribution area and distribution range of all pressure sensors 41 can fill the upper surface of the pedal 20 as much as possible, so as to prevent the stepping area from falling outside the pressure sensor 41 when the foot is stepped on the cover plate 30, resulting in low detection accuracy.

[0047] The number of upper protrusions 32 in each group of protrusions can be designed according to the size of the upper protrusions 32 and the size of the pressure sensor 41, and this application does not limit it. For example, multiple upper protrusions 32 may fall within the orthographic projection range of one pressure sensor 41, that is, one pressure sensor 41 corresponds to multiple upper protrusions 32, and the size of the distribution range of the multiple upper protrusions 32 is slightly smaller than the size of the pressure sensor 41; or, one pressure sensor 41 may correspond to one upper protrusion 32, but the size of the upper protrusion 32 is only slightly smaller than the size of the pressure sensor 41. In this way, the area corresponding to the pressure sensor 41 and the main body 31 can be reduced, the distribution range and number of upper protrusions 32 on the cover plate 30 can be increased, the probability of stepping on the surface of the main body 31 can be reduced, and the anti-slip effect of the cover plate 30 can be improved.

[0048] In one possible embodiment, reference Figure 1 and 2 Multiple pressure sensors 41 can be sequentially distributed along the length of the pedal 20. Further, in one example, the multiple pressure sensors 41 include a first pressure sensor 41, a last pressure sensor 41, and an intermediate pressure sensor 41. The orthographic projection of the intermediate pressure sensor 41 onto the pedal 20 is rectangular, while the orthographic projections of the first and last pressure sensors 41 onto the pedal 20 are non-rectangular polygons. A set of protrusions corresponding to the intermediate pressure sensor 41 includes four upper protrusions 32 and four lower protrusions 33. The four upper protrusions 32 are sequentially spaced along the width direction of the cover plate 30, which is the same as the width direction of the pedal 20. A set of protrusions corresponding to the first pressure sensor 41 includes six upper protrusions 32 and six lower protrusions 33, the distribution range of which is adapted to the shape of the first pressure sensor 41. A set of protrusions corresponding to the last pressure sensor 41 includes six upper protrusions 32 and six lower protrusions 33, the distribution range of which is adapted to the shape of the last pressure sensor 41.

[0049] In one possible implementation, refer to Figure 1The sensor assembly 40 also includes at least one connector 42, through which adjacent pressure sensors 41 are connected together. The first groove 21 includes multiple receiving areas and at least one connecting area, which are alternately distributed. The multiple pressure sensors 41 are located in the multiple receiving areas one-to-one, and the at least one connector 42 is located in the at least one connecting area one-to-one. The pedal 20 also includes limiting protrusions 22 disposed between adjacent receiving areas, with the limiting protrusions 22 spaced between adjacent pressure sensors 41. With this design, under the blocking and limiting action of the limiting protrusions 22, each pressure sensor 41 is limited in the receiving area, and the connector 42 is stably limited in the connecting area, preventing relative movement between adjacent pressure sensors 41 and preventing displacement of pressure sensors 41 during the movement of the electric scooter. This ensures that the sensor assembly 40 can be stably limited in the receiving cavity, ensuring detection accuracy.

[0050] In one possible embodiment, reference Figure 4 The pedal 20 also includes a first connecting hole 25 and a dam 23 located around the first groove 21. The first connecting hole 25 is provided on both the limiting protrusion 22 and the dam 23. The cover plate 30 is provided with a second connecting hole 34. The electric scooter also includes a connecting fastener 71, which passes through the second connecting hole 34 and connects to the first connecting hole 25. Based on this technical solution, the cover plate 30 can be detachably connected to the pedal 20 via the connecting fastener 71. Furthermore, by connecting the fastener 71 to the first connecting hole 25 on the dam 23, the edge of the cover plate 30 and the dam 23 of the pedal 20 can abut against each other, which helps to prevent liquids, dust, and other debris from entering the receiving cavity between the cover plate 30 and the pedal 20 from the periphery of the cover plate 30. Since the limiting protrusion 22 is located between adjacent receiving areas, the limiting protrusion 22 is located in the middle part of the first groove 21. By connecting the fastener 71 to the first connecting hole 25 on the limiting protrusion 22, the middle part of the cover plate 30 can abut against the limiting protrusion 22, which can prevent the middle part of the cover plate 30 from bulging and make the connection between the cover plate 30 and the pedal 20 more reliable. The fastener 71 can be a screw, bolt, or other component.

[0051] Furthermore, in one example, there are multiple first connecting holes 25, with multiple first connecting holes 25 distributed around the first groove 21, and first connecting holes 25 are also provided on the limiting protrusion 22.

[0052] In one example, the dam 23 may include a first-level structure and a second-level structure. The height of the first-level structure relative to the first groove 21 in the vertical direction is lower than the height of the second-level structure relative to the first groove 21 in the vertical direction. A cover plate 30 covers the inner area of ​​the upper surface of the first-level structure, and the second-level structure is disposed in the outer area of ​​the upper surface of the first-level structure, located outside the cover plate 30. Based on this technical solution, the dam 23 is constructed as a stepped structure. The second-level structure is located outside the cover plate 30, which can block the gap between the cover plate 30 and the first-level structure, preventing liquids, dust, and other debris from entering the receiving cavity between the cover plate 30 and the tread 20 through the gap between the cover plate 30 and the first-level structure.

[0053] In one possible implementation, refer to Figure 1 and Figure 4 The electric scooter also includes a power supply. The frame 10 includes a first receiving groove 11 in which the power supply is housed. When the pedal 20 is connected to the frame 10, it covers the opening of the first receiving groove. The pedal 20 is also provided with a second receiving groove 24 and a through hole. The through hole is located on the inner wall of the second receiving groove 24. When the cover plate 30 is connected to the pedal 20, it covers the opening of the second receiving groove 24. The sensor assembly 40 also includes an electronic control module 43 and a conductive wire 44. Each pressure sensor 41 is electrically connected to the electronic control module 43. One end of the conductive wire 44 is connected to the electronic control module 43, and the other end passes through the through hole and extends into the first receiving groove 11. The conductive wire 44 is electrically connected to the power supply.

[0054] Based on the above technical solution, each pressure sensor 41 is connected to a power source via an electronic control module 43, a conductive wire 44, and a power supply. The power source can provide power to the electronic control module 43 through the conductive wire 44, and also provide power to the pressure sensors 41 through the conductive wire 44 and the electronic control module 43. The electronic control module 43 can distribute the power obtained from the conductive wire 44 to each pressure sensor 41. This design allows the power supply wires of the sensor assembly 40 to be concentrated together, avoiding the situation where each pressure sensor 41 is connected to the power source through a single wire. This simplifies the structure and facilitates the assembly and disassembly of the sensor assembly 40. The second receiving groove 24 can limit the movement of the electronic control module 43, and the cover plate 30 covering the opening of the second receiving groove 24 can protect the electronic control module 43, reducing the possibility of liquids, dust, and other debris entering the second receiving groove 24 from the periphery of the cover plate 30 and contaminating the electronic control module 43.

[0055] The electronic control module 43 can be an integrated circuit board. The power supply can be a rechargeable battery.

[0056] In one possible embodiment, the electric scooter further includes a master controller and a master control lead. One end of the master control lead is connected to the master controller, and the other end is located in the first receiving slot 11. The sensor assembly 40 also includes a signal line 45. One end of the signal line 45 is connected to the electronic control module 43, and the other end passes through a through hole into the first receiving slot 11 and is connected to the master control lead. Through the above technical solution, the master controller can be electrically connected to the electronic control module 43 via the master control lead, the signal line 45, and the electronic module can transmit the pressure status of each pressure sensor 41 to the master controller in real time, so that the master controller can determine which pressure sensors 41 are triggered.

[0057] In one example, the master controller can be connected to a power source, which provides power to the master controller.

[0058] In one example, the electric scooter may further include wheels and a drive unit connected by a transmission. The drive unit is connected to a power source to obtain electrical energy and is able to drive the wheels to rotate, thereby moving the electric scooter. A central controller may be electrically connected to the drive unit and, if it determines that the electric scooter is overloaded, can control the drive unit to stop operating. The central controller, power source, wheels, and drive unit are not shown in the accompanying drawings.

[0059] In one example, the master controller can be located in the first receiving slot 11.

[0060] In one example, refer to Figure 1 The signal line 45 and the conductive line 44 can be integrated into a single wire harness, and the end of the single wire harness is provided with a connector. The connector has two interfaces, one of which is connected to the main control lead and the other is connected to the power supply.

[0061] In one possible embodiment, the electronic control module 43 and the multiple pressure sensors 41 are integrally encapsulated. This improves the waterproof performance of the sensor assembly 40, achieving, for example, an IPX7 waterproof rating.

[0062] In one possible embodiment, the pedal 20 includes a first end and a second end opposite to each other. The first end is pivotally connected to the frame 10, and the second end is detachably connected to the frame 10. A second receiving groove 24 is located at the first end of the pedal 20. With this design, when replacing or repairing the power supply, it is only necessary to disconnect the connection between the second end of the pedal 20 and the frame 10, rotate the pedal 20 to expose the first receiving groove 11 of the frame 10, and then remove the power supply from the first receiving groove 11. Moreover, since the pedal 20 is provided with a sensor assembly 40, and the conductive wire 44 of the sensor assembly 40 extends from the second receiving groove 24 into the first receiving groove 11, rotating the pedal 20 when it is necessary to replace or repair the power supply can avoid moving the conductive wire 44 and avoid moving the pedal 20 carrying the conductive wire 44 away from the frame 10. This simplifies the process of moving the pedal 20 to expose the first receiving groove 11 and reduces the probability of the conductive wire 44 being damaged during the replacement or repair of the power supply.

[0063] In one example, the two opposite ends of the pedal 20 along its length are the first end and the second end, respectively.

[0064] In one possible embodiment, reference Figure 1 , Figure 4 and Figure 5 The electric scooter also includes a bracket 50 and a connecting shaft 61. The bracket 50 includes a fixed connecting part 51 and a rotating connecting part 52 that are connected to each other. The fixed connecting part 51 is connected to the frame 10. The rotating connecting part 52 includes a third connecting hole 521. The pedal 20 includes a fourth connecting hole 261 located at a first end. The connecting shaft 61 movably passes through the third connecting hole 521 and the fourth connecting hole 261. In this way, the pedal 20 can rotate about the connecting shaft 61 and relative to the bracket 50.

[0065] In one example, the electric scooter also includes a first screw 62 and a nylon washer 63. The connecting shaft 61 may include a threaded cylinder and a stop at one end of the threaded cylinder. The other end of the threaded cylinder has a threaded connection hole. After the other end of the threaded cylinder passes through the third connection hole 521 and the fourth connection hole 261, the first screw 62 passes through the nylon washer 63 and the threaded connection hole for connection.

[0066] In one example, the pedal 20 includes two ear plates 26 located at the first end, the two ear plates 26 being spaced apart along the width direction of the pedal 20, and a fourth connecting hole 261 being provided on the ear plates 26; a rotating connecting part 52 is inserted between the two ear plates 26, and the third connecting hole 521 and the fourth connecting hole 261 correspond to each other.

[0067] Further reference Figure 5The bracket 50 also includes two limiting plates 53, which are located on opposite sides of the rotating connection part 52. When the rotating connection part 52 is inserted between the two ear plates 26, the ear plates 26 of the pedal 20 are inserted between the rotating connection part 52 and the corresponding limiting plates 53. The limiting plates 53 are located on one side of the connecting shaft 61 in the radial direction of the connecting shaft 61 to avoid connecting rotation.

[0068] In one example, refer to Figure 1 The electric scooter also includes a second screw 72, which passes through the fixed connection part 51 and connects to the bracket 50.

[0069] In one example, at least a portion of the bracket 50 is located in the first receiving groove 11. This improves the aesthetic appearance of the electric scooter.

[0070] In one possible implementation, refer to Figure 1 The electric scooter also includes a flexible foot pad 80, which is shaped to fit the upper surface of the cover plate 30 and covers the upper surface of the cover plate 30. Because the flexible foot pad 80 covers the upper surface of the cover plate 30, it enhances the aesthetics of the electric scooter and improves user comfort. Furthermore, especially when the cover plate 30 is made of stainless steel, its surface is relatively smooth. By laying the fitted flexible foot pad 80, and with the upper protrusions interlocking between the flexible foot pad 80 and the cover plate 30, relative movement between them is unlikely. Therefore, the flexibility of the flexible foot pad 80 improves the anti-slip effect.
