Description

Technical Field

[0001] This application relates to, but is not limited to, the field of self-balancing scooter technology, and particularly to a pedal assembly and a self-balancing scooter. Background Technology

[0002] A self-balancing scooter is a personal transportation device that automatically adjusts its balance. The user controls direction and speed by tilting their body, and the pedals typically serve as a standing platform. However, the pedal assembly in related technologies is complex, increasing costs and making installation and maintenance inconvenient. Utility Model Content

[0003] The pedal assembly provided in this application simplifies the component structure of the pedal assembly, making it easier to install and maintain.

[0004] This application provides a pedal assembly, which includes a housing, a pedal, an elastic component, and a detection component. The pedal is disposed on the outside of the housing and can move relative to the housing in a first direction under the action of an external force. The first direction is the arrangement direction of the pedal and the housing. The elastic component is connected to the pedal and the housing respectively, and at least a portion of the elastic component can move from a first state to a second state under the action of the pedal. The detection component is disposed between the pedal and the housing. During the process of the elastic component moving from the first state to the second state, the detection component is triggered and is used to detect the movement of the pedal.

[0005] The pedal assembly provided in this application has a pedal disposed on the outside of the housing. When a user applies force to the pedal, the pedal can move in a first direction. Since at least a portion of the elastic component can move from a first state to a second state under the action of the pedal, at least a portion of the elastic component can switch states as the force applied by the user to the pedal changes. During the process of the elastic component moving from the first state to the second state, a detection component is triggered. Since the detection component is disposed between the pedal and the housing, it can detect the pedal movement during the state change of the elastic component, thereby detecting whether the pedal is being pressed, i.e., whether a user is standing on the pedal. The pedal assembly disclosed in this application connects the elastic component to the pedal and the housing, enabling the elastic component to switch states with the movement of the pedal. Furthermore, the detection component is disposed between the housing and the pedal, facilitating the triggering of the detection component during the state switching process of the elastic component. Compared with related technologies, the pedal assembly disclosed in this application simplifies the complex transmission mechanism, simplifies the component structure, and facilitates installation and maintenance.

[0006] In one possible implementation of this application, the elastic component includes a moving part and an elastic part. The moving part is connected to the pedal, and the elastic part is connected to the moving part and the housing respectively. The moving part can move from a first state to a second state under the drive of the pedal, and the elastic part generates a restoring force during the movement. The restoring force can restore the moving part from the second state to the first state, so that the detection component returns to the untriggered state.

[0007] In one possible implementation of this application, the elastic part includes two parts, which are distributed on both sides of the detection component.

[0008] In one possible implementation of this application, the housing has a receiving cavity, and the elastic component is disposed in the receiving cavity; the moving part is rotatably connected to the cavity wall of the receiving cavity, and the moving part includes a first extension section and a second extension section. The first extension section extends from the rotation axis of the moving part toward the pedal; the second extension section extends from the rotation axis toward the detection component; the first extension section moves under the action of the pedal, and the first extension section drives the second extension section to rotate relative to the housing, so that the elastic component moves from a first state to a second state, and the second extension section is used to trigger the detection component.

[0009] In one possible implementation of this application, the housing has a through hole on the side facing the pedal, and the through hole is aligned with the first extension section; the pedal includes a pressing part that extends in a first direction toward the through hole and is adapted to the through hole so that the pressing part can pass through the through hole to press against the first extension section.

[0010] In one possible implementation of this application, the pedal assembly further includes a flexible seal, which is sealed to the edge of the through hole of the housing; under the action of the pressing part, the flexible seal can deform in the first direction toward the first extension section, so that the pressing part presses against the first extension section through the flexible seal.

[0011] In one possible implementation of this application, the elastic part is disposed on the side of the second extension section facing the second direction, one end of the elastic part is disposed on the second extension section, and the other end abuts against the housing; wherein, during the process of the elastic component moving from the first state to the second state, the direction of rotation of the second extension section around the rotation axis is the second direction.

[0012] In one possible implementation of this application, an elastic component is disposed inside the pedal, one end of the elastic part is connected to the housing, and the other end extends toward the side away from the housing, and the extension direction of the elastic part has an angle with the first direction. A movable part is disposed at the end of the elastic part away from the housing. During the process of the movable part moving from the first state to the second state, the elastic part deforms so that the movable part moves closer to the housing along the first direction.

[0013] In one possible implementation of this application, the housing includes a first surface for mounting a pedal, and the first surface is a sealed, continuous surface.

[0014] In one possible implementation of this application, the housing has a receiving cavity, the detection component includes a Hall sensor and a magnet, one of the pedal and the receiving cavity is provided with a Hall sensor and the other is provided with a magnet, and the distance between the Hall sensor and the magnet changes during the movement of the elastic component between a first state and a second state.

[0015] This application provides a self-balancing scooter, which includes a wheel assembly, a central control unit, and a pedal assembly of any of the above. The wheel assembly is connected to a housing and is used to drive the self-balancing scooter. The central control unit is electrically connected to a detection component and is used to receive electrical signals generated by the detection component and issue commands to the wheel assembly according to the electrical signals.

[0016] The self-balancing scooter provided in this application, because it includes the pedal assembly of any of the above-mentioned components, has the same technical effect, namely, it simplifies the component structure of the pedal assembly and facilitates installation and maintenance.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0032] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0033] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0034] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0035] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] A self-balancing scooter, also known as a self-balancing vehicle or an electric self-balancing scooter, is a mode of transportation based on dynamic balance technology. The scooter uses sensors (such as gyroscopes and accelerometers) and a control system to monitor the vehicle's posture in real time and drive the motor to adjust the wheel movement to maintain balance. Users control the direction and speed of travel by leaning forward or backward.

[0038] Reference Figure 1 and Figure 2 This application provides a self-balancing scooter 2, which includes a wheel assembly 21, a central control unit, and a pedal assembly 1. The wheel assembly 21 is connected to the housing 11 and is used to drive the self-balancing scooter 2 to move. The central control unit is electrically connected to the detection component 14 and is used to receive electrical signals generated by the detection component 14 and issue commands to the wheel assembly 21 according to the electrical signals.

[0039] In this embodiment, the wheel assembly 21 may include a drive motor, wheels, a braking system, etc. The wheels are connected to the housing 11, and the drive motor is used to drive the wheels to rotate, so as to realize the forward, backward, and turning functions of the balance vehicle 2.

[0040] In this embodiment, the central control unit is electrically connected to the detection component 14. The detection component 14 is used to detect the movement of the pedal 12 under external force and transmit the movement of the pedal 12 to the central control unit. The central control unit sends corresponding control commands to the wheel assembly 21 according to the movement of the pedal 12, such as forward, backward, and steering.

[0041] The self-balancing vehicle 2 in this embodiment of the application can automatically maintain the balance of the self-balancing vehicle 2 and improve safety by cooperating with the detection component 14 and the central control unit to send corresponding control commands to the wheel assembly 21 according to the movement of the pedal 12.

[0042] The footboard typically serves as a standing platform for the user. When force is applied to the footboard, it can trigger sensors to determine whether a person is standing on the self-balancing scooter. In related technologies, the connection structure between the footboard 12 and the housing 11 of the self-balancing scooter uses a linkage mechanism. During assembly, the angles between each linkage need to be precisely adjusted. Furthermore, since there are generally two footboards, the self-balancing scooter requires two sets of connection structures, which increases the cost of the footboard assembly and makes installation and maintenance inconvenient.

[0043] Reference Figure 1 and Figure 4 This application provides a pedal assembly 1, which includes a housing 11, a pedal 12, an elastic component 13, and a detection component 14. The pedal 12 is disposed on the outside of the housing 11 and can move relative to the housing 11 along a first direction X under the action of an external force. The first direction X is the arrangement direction of the pedal 12 and the housing 11. The elastic component 13 is connected to the pedal 12 and the housing 11 respectively, and at least a portion of the elastic component 13 can move from a first state to a second state under the action of the pedal 12. The detection component 14 is disposed between the pedal 12 and the housing 11. During the process of the elastic component 13 moving from the first state to the second state, the detection component 14 is triggered and is used to detect the movement of the pedal 12.

[0044] In the embodiments of this application, reference is made to Figure 2 and Figure 5 The pedal 12 is disposed on the outside of the housing 11. The first direction X is the arrangement direction of the pedal 12 and the housing 11. Movement of the pedal 12 along the first direction X can be understood as the pedal 12 moving towards the side where the housing 11 is located, or the pedal 12 moving away from the housing 11. The first direction X can also be understood as... Figure 2 The direction is from top to bottom or bottom to top; usually, the tire can contact the ground. Figure 2 The lower middle section can also represent the location of the ground.

[0045] In this embodiment, the pedal 12 can be used for interaction between the user and the balance vehicle 2. When the user presses the pedal 12, the pedal 12 will move relative to the housing 11 in the first direction X. This can also be understood as the pedal 12 moving towards the side closer to the ground, or as the distance between the pedal 12 and the housing 11 decreasing, or the pedal 12 being squeezed towards the side where the housing 11 is located.

[0046] In this embodiment, the elastic component 13 is connected to the pedal 12 and the housing 11 respectively. It can be understood that one end of the elastic component 13 is connected to the pedal 12 and the other end is connected to the housing 11, thereby forming a connection or mechanical linkage between the housing 11 and the pedal 12. For example, one end of the spring of the elastic component 13 is hung on the pedal 12 and the other end is hung on the housing 11. As the pedal 12 moves along the first direction X, the spring can be compressed or stretched and store restoring force.

[0047] In this embodiment, the pedal 12 moves under force, which can cause a portion of the elastic component 13 connected to the pedal 12 to move, thereby moving the elastic component 13 from a first state to a second state. The first state can be understood as the initial state of the elastic component 13, and the second state can be understood as the state in which the elastic component 13 deforms or moves under the action of the pedal 12; the elastic component 13 can be in a state where the whole moves from the first state with the movement of the pedal 12, or it can be in a state where a part moves from the first state with the movement of the pedal 12.

[0048] In this embodiment, the detection component 14 can be disposed on the mechanical transmission path between the pedal 12 and the housing 11, so that the detection component 14 can directly or indirectly sense the movement of the pedal 12. For example, the sensor on the housing 11 with the detection component 14 is facing the movement trajectory of the pedal 12, or the detection is indirectly triggered by the deformation of the elastic component 13.

[0049] In this embodiment, the detection component 14 is triggered during the movement of the elastic component 13 from the first state to the second state, or it can be triggered after the elastic component 13 has moved to the second state. The detection component 14 can be triggered by approaching, moving away from, or directly contacting the elastic component 13.

[0050] In this embodiment, the detection component 14 can be used to detect whether the user is standing on the pedal 12. For example, when the user is standing on the pedal 12, the pedal 12 is subjected to force and moves, causing the elastic component 13 to change its state, thereby triggering the detection component 14. The detection component 14 transmits the force situation of the pedal 12 to the central control unit, that is, it detects the instruction that the user is standing on the pedal 12, and the central control unit controls the balance vehicle 2 to move forward. When the user's foot is removed from the pedal 12, the force on the pedal 12 disappears, and the restoring force of the elastic component 13 causes the pedal 12 to move away from the ground. The detection component 14 returns to the untriggered state, that is, it detects the instruction that the user leaves the pedal 12, and the central control unit controls the balance vehicle 2 to shut down, etc.

[0051] In this embodiment of the pedal assembly 1, the pedal 12 is disposed on the outside of the housing 11. When the user applies force to the pedal 12, the pedal 12 can move along the first direction X. Since at least a portion of the elastic component 13 can move from a first state to a second state under the action of the pedal 12, at least a portion of the elastic component 13 can switch states as the force applied by the user to the pedal 12 changes. During the process of the elastic component 13 moving from the first state to the second state, the detection component 14 is triggered. Since the detection component 14 is disposed between the pedal 12 and the housing 11, it can detect changes in the state of the elastic component 13. During the state change process, the movement of pedal 12 can be detected, thereby detecting whether pedal 12 is being pressed, i.e. whether a user is standing on pedal 12. The pedal assembly 1 disclosed in this application connects elastic component 13 to pedal 12 and housing 11, so that elastic component 13 can switch states with the movement of pedal 12. The detection component 14 is disposed between housing 11 and pedal 12, so that elastic component 13 can trigger detection component 14 during state switching. Compared with related technologies, the pedal assembly 1 disclosed in this application simplifies the complex transmission mechanism, simplifies the component structure, and facilitates installation and maintenance.

[0052] The pedal assembly 1 of this application embodiment can also be applied to devices such as electric vehicle control pedals, construction machinery control pedals, and smart home appliance control pedals, which can be triggered by the pedal to detect and issue commands.

[0053] Reference Figure 6 , Figure 8 and Figure 10 In some possible embodiments of this application, the elastic component 13 includes a movable part 131 and an elastic part 132. The movable part 131 is connected to the pedal 12, and the elastic part 132 is connected to the movable part 131 and the housing 11 respectively. The movable part 131 can move from a first state to a second state under the drive of the pedal 12, and the elastic part 132 generates a restoring force during the movement. The restoring force can restore the movable part 131 from the second state to the first state, so that the detection component 14 can be restored to the untriggered state.

[0054] In this embodiment, the moving part 131 is connected to the pedal 12. Force applied to the pedal 12 can be transmitted to the moving part 131, causing it to move. During the process of the moving part 131 returning from the second state to the first state, the moving part 131 can transmit elastic potential energy to the pedal 12, causing the pedal 12 to move along the first direction X. The moving part 131 can be a rigid structure (such as a slider, connecting rod, etc.). The moving part 131 and the pedal 12 can be in contact or a rigid connection, etc.

[0055] In this embodiment, the elastic part 132 is connected to the movable part 131 and the housing 11. When the movable part 131 moves, the portion of the elastic part 132 connected to the housing 11 remains stationary under the action of the housing 11, while the portion of the elastic part 132 connected to the movable part 131 deforms as the movable part 131 moves, thereby storing elastic potential energy in the elastic part 132. The elastic part 132 can be a flexible material such as a spring (coil spring, leaf spring), elastic rubber, or silicone pad.

[0056] In this embodiment of the application, after the pedal 12 is subjected to an external force, the elastic component 13 moves from the first state to the second state. During this process, the elastic part 132 can store elastic potential energy. After the external force on the pedal 12 is removed, the elastic part 132 can move the moving part 131 under the action of the elastic potential energy, and return from the second state to the first state.

[0057] In this embodiment of the application, the pedal assembly 1 is connected to the pedal 12 via the moving part 131, so that the movement of the pedal 12 and the deformation of the elastic part 132 are linked. The deformation process of the elastic part 132 can be automatically reset by the stored elastic potential energy, thereby realizing the automatic reset of the pedal 12 and restoring the detection component 14 to the non-triggered state, thus improving the automation and flexibility of the pedal assembly 1.

[0058] Reference Figure 5 , Figure 7 and Figure 9 In some possible embodiments of this application, the elastic portion 132 includes two parts, and the two elastic portions 132 are distributed on both sides of the detection component 14.

[0059] In this embodiment, the self-balancing scooter 2 typically includes two pedals 12. Each pedal 12 can correspond to one detection component 14, or both pedals 12 can correspond to one detection component 14 simultaneously. For example, the left pedal 12 corresponds to the left detection component 14, and the right pedal 12 corresponds to the right detection component 14. This allows for the detection of the force applied to the pedal 12 by a single foot, improving the flexibility and comprehensiveness of the detection and making the commands issued by the central control component more accurate.

[0060] In this embodiment, two elastic parts 132 are distributed on both sides of the detection component 14, forming symmetrical elastic parts 132 on both sides of the detection component 14. Since the elastic parts 132 are connected to the moving parts 131, when the pedal 12 is subjected to force, the moving parts 131 move, causing the elastic parts 132 on both sides to deform synchronously, making the movement of the moving parts 131 relative to the detection component more stable. After the external force disappears, the elastic parts 132 on both sides release the restoring force in concert, pushing the moving parts 131 back to its original position, and the detection component 14 is reset, improving the stability of the movement process of the moving parts 131 and the process of triggering the detection component.

[0061] Reference Figure 5, Figure 6 , Figure 7 and Figure 8 , Figure 5 The diagram shown is a structural schematic of the elastic component 13 in the first state. Figure 7 The diagram shown is a structural schematic of the elastic component 13 in the second state. In some possible embodiments of this application, the housing 11 has a receiving cavity, and the elastic component 13 is disposed in the receiving cavity. The moving part 131 is rotatably connected to the cavity wall of the receiving cavity. The moving part 131 includes a first extension 1311 and a second extension 1312. The first extension 1311 extends from the rotation axis 1313 of the moving part 131 towards the pedal 12. The second extension 1312 extends from the rotation axis 1313 towards the detection component 14. The first extension 1311 moves under the action of the pedal 12, and the first extension 1311 drives the second extension 1312 to rotate relative to the housing 11, so that the elastic component 13 moves from the first state to the second state. The second extension 1312 is used to trigger the detection component 14.

[0062] In this embodiment, the interior of the housing 11 can be a closed or semi-closed receiving cavity. The receiving cavity integrates the elastic component 13. The cavity wall provides a rotation fulcrum for the moving part 131, such as a bearing hole or a shaft groove. The rotation axis 1313 is the axis of the connection point between the moving part 131 and the inner wall of the receiving cavity, and the moving part 131 rotates about the rotation axis 1313. For example, see [reference]. Figure 6 and Figure 8 The inner wall of the cavity is provided with a bearing hole, and the rotating shaft 1313 of the moving part 131 is rotatably connected to the bearing hole. The axis of rotation of the rotating shaft 1313 in the bearing hole is the line of the rotating shaft 1313 of the moving part 131.

[0063] In the application embodiment, there is an included angle between the first extension segment 1311 and the second extension segment 1312, and the specific value of the included angle can be adjusted according to the requirements.

[0064] In the embodiments of the application, reference is made to Figure 6 and Figure 8Each of the two pedals 12 is provided with a moving part 131 and an elastic part 132 respectively. A detection component 14 is disposed on the top wall of the accommodating space and located between the two pedals 12. Two second extension segments 1312 extend from the rotation axis 1313 to the side where the detection component 14 is located. The end of the first extension segment 1311 away from the rotation axis 1313 abuts against or connects to the pedal 12. When the pedal 12 is subjected to force, the pedal 12 presses down on the end of the second extension segment 1312, causing the second extension segment 1312 to rotate downwards around the rotation axis 1313, and the first extension segment 1311 to rotate upwards around the rotation axis 1313, thereby bringing the end of the first extension segment 1311 away from the rotation axis 1313 closer to the detection component 14. When the second extension segment 1312 rotates upwards to abut against the detection component 14, the detection component 14 is triggered.

[0065] In another embodiment, the detection component 14 is disposed on the bottom wall of the receiving cavity. When the pedal 12 is pressed, the first extension 1311 rotates downward around the rotation axis 1313, and the second extension 1312 rotates upward around the rotation axis 1313. At this time, the second extension 1312 moves away from the detection component 14, and the detection component 14 is triggered. When the second extension 1312 moves close to the detection component 14, the detection component 14 is not triggered.

[0066] In this embodiment of the pedal assembly 1, the elastic component 13 is disposed in the receiving cavity of the housing 11, and the moving part 131 is rotatably connected to the inner wall of the receiving cavity, thereby forming a transmission structure between the first extension section 1311 and the second extension section 1312. The first extension section 1311 converts the linear motion of the pedal 12 into rotational motion, driving the second extension section 1312 to rotate synchronously, so that the second extension section 1312 triggers the detection component 14, thereby reducing transmission loss, improving response speed, and optimizing space utilization through the rotational structure, making the component layout more compact.

[0067] Reference Figure 6 and Figure 8 In some possible embodiments of this application, the elastic part 132 is disposed on the side of the second extension 1312 facing the second direction Y, one end of the elastic part 132 is disposed on the second extension 1312, and the other end abuts against the housing 11; wherein, during the process of the elastic component 13 moving from the first state to the second state, the second extension 1312 rotates around the rotation axis 1313 in the direction of the second direction Y.

[0068] In the embodiments of this application, reference is made to Figure 6 and Figure 8The detection component 14 is disposed on the top wall of the accommodating space. Two elastic parts 132 are respectively disposed on both sides of the detection component 14, corresponding to two moving parts 131. One end of the elastic part 132 is connected to the second extension section 1312, and the other end abuts against the side wall surfaces on both sides of the top wall. The elastic part 132 is disposed on the side of the second extension section 1312 facing the second direction Y, or it can be understood that the elastic part 132 is disposed on the side of the second extension section 1312 facing the side wall of the housing 11. The elastic part 132 is an arc-shaped spring sheet, with the arc-shaped opening facing the side where the second extension section 1312 is located. With this structure, when the first extension section 1311 rotates downward, it drives the second extension section 1312 to rotate along the second direction Y, thereby compressing the elastic part 132. The elastic part 132 stores elastic potential energy. When the elastic part 132 releases the elastic potential energy, it causes the second extension section 1312 to move in the opposite direction of the second direction Y, thereby driving the first extension section 1311 to rotate.

[0069] In this embodiment, the elastic part 132 can deform in the second direction Y. The elastic part 132 can also be other elastic structures, such as springs, torsion springs, leaf springs, rubber, etc.

[0070] In the pedal assembly 1 of this application embodiment, the arrangement direction of the elastic part 132 is consistent with the rotation direction (second direction Y) of the second extension section 1312, so that the elastic part 132 can be directly pushed and compressed by the second extension section 1312 when the pedal 12 is pressed down, thereby improving energy storage efficiency and reducing energy loss during the energy transfer process; it can also improve the space utilization rate inside the housing 11.

[0071] Reference Figure 2 , Figure 4 , Figure 6 and Figure 8 In some possible embodiments of this application, the housing 11 has a through hole 111 on the side facing the pedal 12, and the through hole 111 is aligned with the first extension 1311; the pedal 12 includes a pressing part 121, which extends along the first direction X toward the through hole 111 and is adapted to the through hole 111 so that the pressing part 121 can pass through the through hole 111 and press against the first extension 1311.

[0072] In this embodiment, when the elastic component 13 is in the first state, the first extension 1311 extends out from the through hole 111 and abuts against or connects with the pressing part 121 of the pedal 12. When the pedal 12 is pressed down, the pressing part 121 presses down on the first extension 1311 along the first direction X. The first extension 1311 rotates and moves into the housing 11 relative to the through hole 111. As the pressing part 121 presses down, the first extension 1311 passes through the through hole 111 and enters the receiving space. During the process of the elastic component 13 moving from the second state to the first state under the action of the elastic potential energy of the elastic part 132, the elastic part 132 releases the elastic potential energy. The second extension 1312 rotates downward, the first extension 1311 rotates upward, and the end of the first extension 1311 connected to the pedal 12 can pass through the through hole 111, pushing the pedal 12 back to the initial position.

[0073] In this embodiment, the shape of the through hole 111 can be rectangular, circular, etc., and can be adjusted according to the shape of the pressing part 121. The end of the first extension 1311 connected to the pedal 12 can pass through the through hole 111.

[0074] The pedal assembly 1 of this application embodiment achieves direct mechanical linkage between the pedal 12 and the first extension section 1311 by providing a through hole 111 on the side of the housing 11 facing the pedal 12 and aligning the pressing part 121 of the pedal 12 with the through hole 111. This allows the first extension section 1311 to move with the pedal 12. In the first state, the first extension section 1311 passes through the through hole 111 and presses against the pedal 12. In the second state, the pressing part 121 presses down and presses against the first extension section 1311 to gradually enter the receiving cavity, thereby improving the stability of the transmission between the pedal 12 and the moving part 131.

[0075] In some possible embodiments of this application, the pedal assembly 1 further includes a flexible seal, which is sealed to the edge of the through hole 111 of the housing 11; under the action of the pressing part 121, the flexible seal can deform along the first direction X toward the first extension 1311 so that the pressing part 121 presses against the first extension 1311 through the flexible seal.

[0076] In this embodiment, the flexible sealing element (such as rubber bellows, silicone membrane, etc.) and the edge of the housing 11 through the through hole 111 are sealed together by interference fit, adhesive or hot melt, which improves the sealing performance and reduces the intrusion of external dust and liquid into the housing 11.

[0077] In this embodiment, when the pedal 12 is pressed, the pressing part 121 pushes the flexible seal to deform in the direction of the first extension section 1311, so that the flexible seal deforms with the movement of the pedal 12 while maintaining the sealing performance; when the pedal 12 is reset, the flexible seal recovers its original shape by its own elasticity.

[0078] In this embodiment of the pedal assembly 1, the flexible seal is sealed to the edge of the through hole 111 of the housing 11, thus optimizing the sealing performance and durability of the pedal assembly 1. Furthermore, since the elastic deformation of the flexible seal does not interfere with the pressure transmission from the pressure-receiving part 121 to the first extension 1311, it can simultaneously seal the housing 11 and transmit power from the pressure-receiving part 121 to the first extension 1311, thereby triggering the detection component 14.

[0079] Reference Figure 9 , Figure 10 , Figure 11 and Figure 12 In some possible embodiments of this application, the elastic component 13 is disposed inside the pedal 12, one end of the elastic part 132 is connected to the housing 11, and the other end extends toward the side away from the housing 11, and the extension direction of the elastic part 132 has an angle with the first direction X, and the moving part 131 is disposed at the end of the elastic part 132 away from the housing 11; during the process of the moving part 131 moving from the first state to the second state, the elastic part 132 deforms so that the moving part 131 moves closer to the housing 11 along the first direction X.

[0080] In this embodiment of the application, the process of the moving part 131 moving from the first state to the second state can be understood as the distance between the moving part 131 and the surface of the housing 11 in the first state being greater than the distance between the moving part 131 and the surface of the housing 11 in the second state.

[0081] In this embodiment, each of the two pedals 12 is provided with an elastic component 13. Each elastic component 13 includes a moving part 131 and two elastic parts 132. The two elastic parts 132 are distributed on both sides of the moving part 131. A detection element is provided in the area of ​​the moving part 131 corresponding to the housing 11. During the process of the moving part 131 moving from the first state to the second state, the detection element is triggered. The elastic parts 132 can be made of materials such as spring steel, silicone, or rubber.

[0082] In the embodiments of this application, reference is made to Figure 11 and Figure 12 When the moving part 131 is pressed, the moving part 131 moves downward along the first direction X under load, which pushes the elastic part 132 to deform and realize energy storage; when the pedal 12 is released, the elastic part 132 restores its deformation, pushes the moving part 131 to move upward along the first direction X, and pushes the pedal 12 to reset.

[0083] In this embodiment, the pedal 12 consists of an elastic component 13 and a foam pad. The elastic component 13 can be made of plastic and has an elastic part 132 designed to provide a rebound force for the pedal 12 during up-and-down movement. The foam pad is formed by foaming and molding to wrap the elastic component 13 into an integral structure, making the structure of the pedal 12 simple and low-cost.

[0084] In the pedal assembly 1 of this application embodiment, the elastic component 13 is disposed inside the pedal 12, which reuses the space inside the pedal 12, reduces the connection and transmission between the pedal 12 and the internal structure of the housing 11, makes the structure of the pedal assembly 1 simpler, and also reduces the structure and openings on the housing 11, thereby improving the overall integrity of the housing 11.

[0085] In some possible embodiments of this application, the housing 11 includes a first surface for mounting the pedal 12, and the first surface is a sealed, continuous surface.

[0086] In this embodiment of the application, the housing 11 can be integrally formed, and the housing 11 can also include an upper shell and a lower shell. For example, the lower shell of the housing 11 is used to house the tire, and the upper shell is used to house the pedal 12 and the elastic component 13.

[0087] In this embodiment, the first surface of the housing 11 is used to set the pedal 12. The first surface is a sealed and continuous surface, which means that the first surface does not have through holes 111 or gaps. The structure of the first surface achieves airtight and liquid-tight sealing through integral molding or welding process.

[0088] In the pedal assembly 1 of this application embodiment, the first surface on which the pedal 12 is mounted is a sealed and continuous surface, which can improve the sealing and waterproof performance of the housing 11, and also improve the integrity and aesthetics of the housing 11.

[0089] Reference Figure 3 In related technologies, the scheme where two pedals each correspond to a detection component requires drilling holes in the scooter's shell to install elastic light-shielding elements to trigger photoelectric switches, followed by waterproofing and sealing. This increases costs and results in an incomplete and less aesthetically pleasing appearance of the scooter's upper surface. (Refer to...) Figure 11 and Figure 12 In some possible embodiments of this application, the housing 11 has a receiving cavity, the detection component 14 includes a Hall sensor 141 and a magnet 142, one of the pedal 12 and the receiving cavity is provided with the Hall sensor 141 and the other is provided with the magnet 142, and the distance between the Hall sensor 141 and the magnet 142 changes during the movement of the elastic component 13 between the first state and the second state.

[0090] In this embodiment, the Hall sensor 141 can be disposed in one of the pedal 12 or the receiving cavity, and correspondingly, the magnet 142 is disposed in the other.

[0091] In this embodiment of the application, during the movement of the elastic component 13 between the first state and the second state, the distance between the magnet 142 and the Hall sensor 141 changes, thereby enabling the acquisition of the signal change of the Hall sensor 141.

[0092] For example, a magnet 142 is disposed within the pedal 12. The moving part 131 includes a mounting groove 1314 for mounting the magnet 142. A Hall sensor 141 is disposed within the receiving cavity. The pedal 12 can drive the magnet 142 to move up and down. The magnetic field passes through the vehicle body and acts on the Hall sensor 141. The controller 15 reads the signal changes of the Hall sensor 141 and determines whether a person is standing on the pedal 12 according to a set program. When the pedal 12 is pressed down, the magnet 142 approaches the Hall sensor 141, and the signal of the Hall sensor 141 changes, indicating that a person is standing on the pedal 12. When the pedal 12 returns to its original position, the magnet 142 moves away from the Hall sensor 141, and the signal of the Hall sensor 141 changes, indicating that no one is standing on the pedal 12.

[0093] The pedal assembly 1 of this application embodiment can reduce the number of openings in the housing 11 by sensing through the Hall sensor 141 and the magnet 142. Compared with the related technology, which requires openings in the housing 11 for sensing by a photosensitive sensor, the pedal assembly 1 of this application embodiment improves the structural integrity of the housing 11 and simplifies the structure of the housing 11.
