Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle body, in particular to a pedal structure and a vehicle. BACKGROUND

[0002] In the related art, SUV (Sport Utility Vehicle) is usually provided with a pedal to assist passengers to get on and off the vehicle conveniently and safely, so as to reduce the height difference of getting on and off the vehicle and improve the convenience and safety of getting on and off the vehicle. However, the function design of the existing pedal is relatively single, and only the basic supporting function can be realized, and the utility is poor. When the passenger gets on the vehicle through the pedal, the foreign matter on the bottom of the passenger's foot will be directly brought into the cabin with the pedaling action of the foot, and attached to the interior parts such as the seat and the carpet. The above-mentioned foreign matter not only seriously damages the clean environment inside the cabin, but also greatly increases the frequency of cleaning the cabin and the cost of health maintenance. SUMMARY

[0003] Therefore, the present application aims to provide a pedal structure with good utility.

[0004] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows: A pedal structure suitable for being arranged on a vehicle body of a vehicle, comprising a pedal body with a cleaning port at the top, a first driving part and a cleaning part arranged on the pedal body, a shielding part in transmission connection with the first driving part, and a transmission part arranged between the shielding part and the cleaning part; The first driving part can drive the shielding part to act and switch the shielding part between a first state and a second state, and in the first state, the shielding part shields the cleaning port, and in the second state, the shielding part opens the cleaning port; In the process of switching the shielding part from the first state to the second state, the transmission part can drive the cleaning part to act, and at least part of the cleaning part is stretched out above the pedal body through the cleaning port.

[0005] Further, the first driving part is used for outputting linear power, and the shielding part comprises a cover plate slidingly arranged on the pedal body along a preset path; In the first state, the cover plate is flush with the top of the pedal body, and in the second state, the cover plate is accommodated in the pedal body.

[0006] Further, the cover plate and the first driving part are in transmission connection through a transmission rod, and the two ends of the transmission rod are respectively hingedly connected with the cover plate and the driving shaft of the first driving part.

[0007] Further, a sliding groove defining the preset path is arranged on the pedal body. The slide groove includes a first portion extending along the linear power output direction of the first drive unit, and a second portion disposed at one end of the first portion, the second portion being an arc shape that curves toward the top of the pedal body.

[0008] Furthermore, the transmission part includes a rack portion disposed on the cover plate and a drive rod rotatably disposed on the pedal body, and the cleaning part includes a cleaning wheel that is pulsatorically connected to the drive rod; The rack portion extends along the power output direction of the first drive unit, and one end of the drive rod is provided with a toothed portion that meshes with the rack portion. The cover plate can drive the drive rod to rotate through the toothed portion and drive the cleaning wheel to move.

[0009] Furthermore, the rack portion is located at the end of the cover plate away from the first drive unit, and the length of the rack portion is less than the length of the cover plate.

[0010] Furthermore, the cleaning wheel is slidably mounted on the pedal body in the vertical direction; The cleaning wheel is hinged to the driving rod via a driven rod, and the cleaning wheel can switch between a usage state in which it partially extends above the pedal body and a storage state in which it is housed within the pedal body.

[0011] Furthermore, the pedal body is provided with a second drive unit, which is arranged corresponding to the cleaning wheel and is used to output rotational power; A connecting part is provided between the power shaft of the second drive unit and the rotating shaft of the cleaning wheel. The connecting part can connect the cleaning wheel and the second drive unit together to drive the cleaning wheel to rotate.

[0012] Furthermore, the connecting portion includes a slot provided at the end of the power shaft and a plug provided at the end of the rotating shaft; The slot has a notch at the bottom, through which the insert can be inserted into the slot and rotate synchronously with the power shaft.

[0013] Compared with related technologies, this application has the following advantages: (1) The pedal structure described in this application, through the linkage design of the cleaning part and the shielding part, not only enables the pedal to serve as an auxiliary support for getting in and out of the vehicle, but also serves to clean the soles of the shoes of the driver and passengers, thus having good functionality. Furthermore, when the passenger needs to use the pedal, during the process of the shielding part switching from the closed state to the open state, the cleaning part extends out above the pedal body simultaneously, which can directly pre-treat foreign objects such as mud and dust on the soles of the shoes, effectively blocking foreign objects from entering the cabin from the source, effectively solving the problem of damaged cabin cleanliness, thereby greatly reducing the frequency of cabin cleaning.

[0014] (2) The drive unit adopts a linear power output design, which can greatly simplify the connection structure between the drive system and the shield. This design not only reduces the number of parts, but also makes full use of the linear space inside the pedal body, which is convenient for layout and implementation. In addition, when the shield is in the first state (shielding the cleaning port), the cover plate is flush with the top of the pedal body, which can form a complete and flat stepping surface, which not only helps to ensure the overall exquisiteness of the pedal body, but also helps to provide stable support.

[0015] (3) By connecting the cover plate and the drive unit through the transmission rod, when the drive shaft of the drive unit makes a linear reciprocating motion, the transmission rod can adaptively adjust the angle through the hinge points at both ends, avoiding the lag caused by a slight deviation between the power output direction and the sliding direction of the cover plate, which helps to ensure that the linear power of the drive shaft can be completely converted into the sliding power of the cover plate without power loss.

[0016] (4) By making the slide groove include a straight first part and an arc-shaped second part, when the cover plate switches from the first state to the second state, it can first move along the arc-shaped second part and gradually bend downwards into the interior of the pedal body to be located below the cleaning port. Then, it slides in a straight line along the first part, away from the cleaning port area, and finally completes the receiving. The slide groove with this structure can effectively avoid interference between the cover plate and the pedal body during the movement, which helps to ensure smooth state switching.

[0017] (5) By directly meshing the rack portion on the cover plate with the toothed portion of the drive rod, when the cover plate slides in a straight line under the action of the first drive unit, the drive rod drives the cleaning wheel to move. This transmission path requires no power loss, has a fast response speed, and can quickly realize the movement of the cleaning wheel. Moreover, the meshing transmission of the rack and the tooth has a high load-bearing capacity and can withstand the reaction force generated when the cleaning wheel contacts the sole of the shoe.

[0018] (6) By making the length of the rack part less than the length of the cover plate, the cleaning wheel does not need to follow the cover plate to complete the entire sliding stroke. This can better control the extension and retraction of the cleaning wheel, reduce the meshing time between the rack part and the toothed part, reduce component wear, and effectively extend the service life of the transmission structure.

[0019] (7) By using shorter driving and driven rods, the cleaning wheel can achieve a larger up-and-down sliding stroke within a smaller rotation radius, thus enabling a larger stroke within a smaller space. This facilitates the switching of the cleaning wheel between the storage state and the use state, and makes it easier to arrange.

[0020] (8) The rotational power output by the second drive unit is transmitted to the cleaning wheel through the connecting part, so that the cleaning wheel has an active rotation function when in use (extending above the pedal body). It can not only quickly remove foreign objects from the soles of shoes, but also quickly throw the cleaned foreign objects off the surface of the cleaning wheel, preventing foreign objects from adhering to the soles of shoes or the cleaning wheel again, thus achieving a better cleaning effect.

[0021] (9) By including a slot and a plug in the connecting part, when the cleaning wheel descends from the use state to the storage state, the plug can be directly disengaged from the notch in the vertical direction, realizing the automatic disconnection of the connecting part, and the disconnection process does not require additional driving components. This design can better adapt to the needs of the cleaning wheel to switch between vertical and horizontal movements, effectively avoid interference of the connecting part with the lifting trajectory of the cleaning wheel, and ensure that the state switching process is smooth and unobstructed.

[0022] Another object of this application is to provide a vehicle having a pedal structure as described above.

[0023] The vehicle described in this application, by setting up the pedal structure as described above, can clean the soles of the driver's and passengers' shoes, effectively maintaining the cleanliness of the cabin and improving the overall quality. Attached Figure Description

[0026] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0028] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0030] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides a pedal structure that enables cleaning of the bottom of the driver's or passenger's feet, thus providing good functionality.

[0033] In related technologies, among various vehicle types, SUVs (Sport Utility Vehicles) are favored by consumers due to their spacious interiors, good off-road capability, and adaptability to various road conditions. However, to meet off-road requirements, these vehicles generally employ a high chassis design, which can pose challenges for the elderly, children, and people with mobility impairments when getting in and out. Therefore, to assist passengers in getting in and out of the vehicle conveniently and safely, these vehicles typically include a running board, providing a central support platform to reduce the height difference and improve ease and safety.

[0034] However, the existing pedal design is relatively simple, only providing basic support and failing to consider the handling of foreign objects such as mud, dust, rainwater, and snow particles that may adhere to the soles of passengers' shoes before they board the vehicle. In everyday use, after walking outdoors, passengers' shoes easily accumulate these foreign objects. When passengers step onto the pedal, these objects are directly brought into the cabin and adhere to interior components such as seats and carpets. Furthermore, the introduction of these foreign objects not only severely compromises the cleanliness of the cabin interior but may also pose a potential threat to the health of passengers.

[0035] Furthermore, the frequent introduction of foreign objects significantly increases the frequency of cabin cleaning and maintenance costs. Car owners need to regularly spend time and effort cleaning the cabin interior, which is not only time-consuming but also increases cleaning costs. At the same time, long-term and repeated cleaning operations may also cause wear and tear on the cabin interior materials, shortening the lifespan of interior components and further increasing the vehicle's operating costs.

[0036] In existing technologies related to side pedal cleaning, most solutions only focus on "cleaning the pedal body 1 itself" (such as removing accumulated mud and sand from the pedal surface through spraying or scraping mechanisms). Their core design logic is limited to "maintaining the cleanliness of the pedal body 1," but they generally lack active cleaning structures designed for the soles of the driver's and passengers' shoes. Moreover, the core source of foreign object contamination inside the cabin is not the pedal body itself, but rather the external dirt carried by the soles of the driver's and passengers' shoes.

[0037] Existing technology only cleans the pedal itself, but does not pre-treat the soles of the shoes before the user enters the cabin. As a result, dirt on the soles can still be transferred to areas such as the cabin floor mats and under the seats through the stepping action, failing to block the pollution at its source.

[0038] In view of this, in order to overcome the shortcomings of the related technology, the pedal structure of this embodiment is designed as follows: the pedal body 1 has a cleaning port K on the top, a first driving part and a cleaning part are provided on the pedal body 1, a blocking part is connected to the driving part, and a transmission part is provided between the blocking part and the cleaning part.

[0039] The first drive unit can drive the blocking unit to move and switch the blocking unit between a first state and a second state. In the first state, the blocking unit blocks the cleaning port K, and in the second state, the blocking unit opens the cleaning port K. During the process of the blocking unit switching from the first state to the second state, the transmission unit can drive the cleaning unit to move and cause at least part of the cleaning unit to extend through the cleaning port K to the top of the pedal body 1.

[0040] Therefore, through the coordinated design of the cleaning section and the shielding section, the pedal not only serves as an auxiliary support for getting in and out of the vehicle, but also cleans the soles of the driver's and passengers' shoes, thus possessing good functionality. Furthermore, when the occupant needs to use the pedal, as the shielding section switches from the closed to the open state, the cleaning section simultaneously extends above the pedal body 1, directly pre-treating mud, sand, dust, and other foreign objects from the soles of the shoes. This effectively prevents foreign objects from entering the cabin at the source, effectively solving the problem of compromised cabin cleanliness and thus significantly reducing the frequency of cabin cleaning.

[0041] Furthermore, in the non-use state (first state), the shielding part closes the cleaning port K, preventing mud, sand, and rainwater from entering the pedal body 1 during driving. This effectively avoids malfunctions in the cleaning and transmission parts due to foreign object intrusion, while also maintaining the integrity and aesthetics of the pedal surface. In addition, integrating the drive unit, shielding part, cleaning unit, and transmission unit inside the pedal body 1 eliminates the need for additional space on the side of the vehicle. Moreover, the synchronized opening of the cover 2 and the extension of the cleaning part avoids interference between the cleaning part and the cover 2 when it is not fully open, and also effectively eliminates the need for a separate drive component for the cleaning part, reducing the number of parts and lowering production and maintenance costs.

[0042] Based on the above overall introduction, specifically, combined with Figures 1 to 14As shown, the pedal body 1 extends along the length of the vehicle and spans the front and rear door areas to provide support for front and rear passengers getting in and out of the vehicle. In this embodiment, as a specific example, the cleaning port K is specifically located in the middle between the front and rear doors. This design allows the cleaning part to extend and cover the foot areas of both front and rear passengers, thus providing cleaning services for the soles of shoes of both front and rear passengers before they get in the vehicle, effectively meeting the usage needs of passengers in different seats.

[0043] It is understandable that, in addition to setting the cleaning port K to be located in the middle of the front and rear doors, two cleaning ports K can also be set on the pedal body 1, with the front cleaning port K corresponding to the front door and the rear cleaning port K corresponding to the rear door.

[0044] Combination Figure 3 and Figure 4 As shown in the illustration, in a specific embodiment, the pedal body 1 includes a bracket 102 with an internal cavity, a plate 101 covering the top of the bracket 102, and a plurality of connecting brackets 103 spaced apart along the length of the bracket 102. The bracket 102 comprises two separate parts arranged at intervals to form a clearance space. One end of each connecting bracket 103 has a connecting arm extending towards the vehicle body and is connected to the vehicle body via this connecting arm. The other end of the connecting bracket 103 is screwed to the bracket 102, and the plate 101 is adhered to the top of the bracket 102 with adhesive tape.

[0045] In some exemplary embodiments, the first drive unit outputs linear power, and the shielding part includes a cover plate 2 that slides along a preset path on the pedal body 1. Furthermore, in a first state, the cover plate 2 is flush with the top of the pedal body 1, and in a second state, the cover plate 2 is housed within the pedal body 1. Here, the drive unit employs a linear power output design, and the transmission structure formed by the cover plate 2 sliding along the preset path with the shielding part significantly simplifies the connection structure between the drive system and the shielding part. This design not only reduces the number of parts but also makes full use of the linear space inside the pedal body 1, facilitating its implementation.

[0046] Furthermore, when the shielding part is in the first state (shielding the cleaning port K), the cover plate 2 is flush with the top of the pedal body 1, forming a complete and flat step surface. This not only helps maintain the overall refined appearance of the pedal body 1 but also provides stable support. In the second state, the shielding part is housed within the pedal body 1, allowing the pedal structure to maintain a compact volume when not in use. This effectively prevents interference to the driver and passengers caused by the cover plate 2 being exposed in other locations. It also effectively prevents the cover plate 2 from interfering with the cleaning wheel 7.

[0047] CombinationFigures 15 to 17 As shown in the illustration, in a specific embodiment, the cleaning port K is rectangular to facilitate the processing of the brake, and in the second state, the cover plate 2 is located on one side of the cleaning wheel 7 to prevent interference with the cleaning wheel 7. The plate 101 of the pedal body 1 is as follows... Figure 17 As shown, it includes two side panel portions arranged opposite each other, and a top panel portion located between the two side panel portions, and the side panel portion closer to the vehicle body has an upwardly extending and inwardly folded flange.

[0048] In addition, similar to related technologies, in order to improve the safety of the pedal body 1, in specific implementation, multiple anti-slip protrusions or anti-slip textures can be provided on the plate 101 of the pedal body 1, or a panel with anti-slip protrusions can be further provided on the top of the pedal body 1.

[0049] It should be noted that the shape of the cleaning port K is not limited to the rectangle shown in the figure. It can also be designed as a circle or other shapes according to design requirements.

[0050] In some exemplary embodiments, the cover plate 2 and the first drive unit are connected by a transmission rod 4, with both ends of the transmission rod 4 hinged to the drive shafts of the cover plate 2 and the first drive unit, respectively. This configuration allows the transmission rod 4 to adaptively adjust its angle via the hinge points at both ends when the drive shaft of the first drive unit performs linear reciprocating motion. This avoids lag caused by slight deviations between the power output direction and the sliding direction of the cover plate 2, ensuring that the linear power of the drive shaft is completely converted into the sliding power of the cover plate 2 without power loss. Furthermore, this configuration allows the drive shaft of the first drive unit and the cover plate 2 to be at different heights, facilitating the housing of the first drive unit within the pedal body 1.

[0051] In specific implementation, such as Figures 4 to 5 In this design, the first drive unit is specifically a first motor 3 mounted on the pedal body 1, and the first motor 3 is specifically located in the cavity of the bracket 102 of the pedal body 1 and is screwed onto the bracket 102. In addition, the drive shaft of the first motor 3 can be directly hinged to the transmission rod 4, or a connecting shaft can be additionally provided on the drive shaft and connected to the transmission rod 4 through the connecting shaft.

[0052] Combination Figures 18 to 20 As shown, the cover plate 2 can be set as a rectangle adapted to the location of the cleaning port K, so that when the cover plate 2 is in the first state of blocking the cleaning port K, the overall integrity of the pedal body 1 can be maintained, thereby giving the pedal body 1 a better sense of refinement. At this time, in order to facilitate the connection between the cover plate 2 and the transmission rod 4, as shown... Figure 12As shown, a downwardly protruding connecting lug is provided at the end of the cover plate 2 near the first motor 3. Furthermore, a connecting hole is provided on this connecting lug, and the cover plate 2 is hinged to the transmission rod 4 via a hinge shaft passing through this connecting hole.

[0053] It should be noted that, in addition to hinged connection between the drive shaft of the first motor 3 and the cover plate 2 via the transmission rod 4, the drive shaft of the first motor 3 can also be directly connected to the cover plate 2. However, in this case, in order to facilitate the housing of the first motor 3 within the pedal body 1, a downwardly protruding receiving block needs to be provided at the bottom of the cover plate 2, which obviously increases the volume and space occupied by the cover plate 2, and is not conducive to its arrangement within the pedal body 1.

[0054] In some exemplary embodiments, the pedal body 1 is provided with a groove 1011 that defines a preset path. The groove 1011 includes a first portion 10111 extending along the linear power output direction of the first drive unit, and a second portion 10112 located at one end of the first portion 10111. The second portion 10112 is an arc shape that curves toward the top of the pedal body 1.

[0055] At this time, by making the slide groove 1011 include a straight first part 10111 and an arc-shaped second part 10112, when the cover plate 2 switches from the first state (blocking the cleaning port K) to the second state (accommodated in the pedal body 1), it can first move along the arc-shaped second part 10112 to gradually bend downwards into the pedal body 1 so as to be located below the cleaning port K.

[0056] Then, it slides in a straight line along the first part 10111, away from the cleaning port K area, and finally completes the receiving. The slide groove 1011 of this structure can effectively avoid interference between the cover plate 2 and the pedal body 1 during the movement, which helps to ensure smooth state switching.

[0057] In some exemplary embodiments, the transmission unit includes a rack portion 202 disposed on the cover plate 2 and a drive rod 5 rotatably disposed on the pedal body 1, and the cleaning unit includes a cleaning wheel 7 tractively connected to the drive rod 5. The rack portion 202 extends along the power output direction of the first drive unit, and one end of the drive rod 5 is provided with a toothed portion 501 that meshes with the rack portion 202. The cover plate 2 can drive the drive rod 5 to rotate via the toothed portion 501, thereby actuating the cleaning wheel 7.

[0058] By directly engaging the rack portion 202 on the cover plate 2 with the toothed portion 501 of the drive rod 5, when the cover plate 2 slides linearly under the action of the first drive unit, the linear motion of the rack is directly converted into the rotational motion of the drive rod 5 through the tooth engagement, and then the drive rod 5 drives the cleaning wheel 7 to move. This transmission path requires no power loss, has a fast response speed, and can quickly realize the movement of the cleaning wheel 7. Moreover, the meshing transmission between the rack and the tooth has a high load-bearing capacity and can withstand the reaction force generated when the cleaning wheel 7 contacts the sole of the shoe (such as the pressure when the occupant steps on it).

[0059] In specific implementation, it can be as follows: Figures 16 to 20 As shown, the cover plate 2 is set as a rectangle adapted to the cleaning port K, and sliders 201 are respectively set on the left and right sides of the cover plate 2. In order to improve the sliding stability of the cover plate 2, there are two sliders 201 on each side. Correspondingly, there are grooves 1011 on both opposite sides of the pedal body 1, and there are two grooves 1011 on each side that correspond one-to-one with the sliders 201 on the corresponding side.

[0060] In addition, such as Figure 16 As shown, the two slide grooves 1011 on each side are connected, and the second part 10112 is located at the end of each slide groove 1011 away from the first motor 3. Furthermore, in conjunction with... Figure 9 and Figure 20 As shown, each slider 201 includes a block 2011 connected to the cover plate 2, and a rod 2012 extending outward from the block 2011. The rod 2012 is slidably inserted into the groove 1011 and slides against the side wall of the groove 1011 to guide the sliding of the cover plate 2.

[0061] In addition, such as Figure 9 As shown, in order to ensure that the top of the cover plate 2 is flush with the top of the pedal body 1 in the first state, the block 2011 of the slider 201 protrudes outward from the cover plate 2, and a limiting part 10113 is provided on the plate 101 of the pedal body 1. The limiting part 10113 can abut against the block 2011 of the slider 201 when the cover plate 2 is in the first state, thereby ensuring that the top of the cover plate 2 is flush with the top of the pedal body 1.

[0062] In some exemplary embodiments, the rack portion 202 is located at the end of the cover plate 2 away from the first drive unit, and the length of the rack portion 202 is less than the length of the cover plate 2. The advantage of this design is that the rack engages with the toothed portion 501 of the drive rod 5 only during specific phases of the cover plate 2's sliding motion. When the cover plate 2 switches from the first state to the second state, the rack portion 202 first contacts the toothed portion 501 and drives the drive rod 5 to rotate (synchronously driving the cleaning wheel 7 to retract).

[0063] When the cover plate 2 slides to the preset position, the rack portion 202 disengages from the toothed portion 501, the drive rod 5 stops rotating, and the cleaning wheel 7 remains in the retracted state. This allows the cleaning wheel 7 to avoid following the cover plate 2 through its entire sliding stroke, thus better controlling the extension and retraction of the cleaning wheel 7, reducing the engagement time between the rack portion 202 and the toothed portion 501, reducing component wear, and effectively extending the lifespan of the transmission structure. Simultaneously, it also reduces the overall weight of the cover plate 2, lowers the power load on the first drive unit, and reduces the sliding energy consumption of the cover plate 2.

[0064] In specific implementation, it can be as follows: Figure 20 As shown, the rack portion 202 is located at the end of the cover plate 2 away from the first motor 3 and extends along the length of the cover plate 2. Furthermore, to further improve the transmission stability between the cover plate 2 and the cleaning wheel 7, as shown... Figure 20 As shown, the rack portions 202 are two located on opposite sides of the cover plate 2 body.

[0065] And it is understandable that, in addition to Figure 20 The two rack portions 202 arranged opposite to each other shown can also be provided on the cover plate 2 with only one rack portion 202. In addition, besides making the length of the rack portion 202 less than the length of the cover plate 2, the length of the rack portion 202 can also be adapted to the length of the cover plate 2, that is, equal to the length of the cover plate 2.

[0066] In some exemplary embodiments, the cleaning wheel 7 is slidably disposed on the pedal body 1 in the vertical direction. The cleaning wheel 7 is hinged to the driving rod 5 via the driven rod 6, and the cleaning wheel 7 can switch between a usage state in which it partially extends above the pedal body 1 and a storage state in which it is housed within the pedal body 1.

[0067] Therefore, when the driving rod 5 rotates under the drive of the rack part 202, the driven rod 6 transmits power to the hinge point of the cleaning wheel 7 through the circumferential motion of the hinge point with the driving rod 5. After the angle of the driven rod 6 is adjusted, it can be finally converted into the linear sliding of the cleaning wheel 7 in the up and down direction, and realize the switching between the use state and the storage state of the cleaning wheel 7. This makes the movement path of the cleaning wheel 7 simple and facilitates its arrangement in the pedal body 1.

[0068] Moreover, by utilizing shorter drive rods 5 and driven rods 6, the cleaning wheel 7 can achieve a larger vertical sliding stroke within a smaller rotation radius, thus enabling a larger stroke within a smaller space. This facilitates the switching of the cleaning wheel 7 between its storage and usage states, making it particularly suitable for vehicles with limited chassis clearance.

[0069] In specific implementation, it can be as follows: Figure 19 and Figure 21As shown, the driving rod 5 and the driven rod 6 are respectively provided in a one-to-one correspondence with the two rack parts 202. Each driving rod 5 has a connecting hole at one end and a connecting shaft at the other end. The toothed part 501 is specifically an arc shape arranged circumferentially along the connecting hole. The two driving rods 5 are rotatably mounted on the plate 101 of the pedal body 1 through a mounting shaft.

[0070] The cleaning wheel 7 is provided with a rotating shaft 701 that runs through it axially, and the rotating shaft 701 extends to both ends of the cleaning wheel 7. One end of the driven rod 6 is rotatably mounted on the mounting shaft of the driving rod 5, and the other end is sleeved on the rotating shaft 701, thereby realizing the hinged connection between the driving rod 5 and the cleaning wheel 7.

[0071] In addition, such as Figure 8 and Figure 16 As shown, the pedal body 1 has a guide groove 1012 arranged vertically on its plate 101. The rotating shaft 701 of the cleaning wheel 7 is inserted into the guide groove 1012 to guide the cleaning wheel 7 to slide up and down. In addition, the cleaning wheel 7 can be made of an elastic material (such as rubber, soft silicone, etc.).

[0072] On the one hand, when a passenger steps on the cleaning wheel 7, the cleaning wheel 7 will adaptively deform and contract under the force of stepping. This deformation not only allows the cleaning structure on the surface of the cleaning wheel 7 (such as brushes and raised patterns) to fit more closely to the sole pattern, but also significantly improves the cleaning power for mud, sand, dust and other foreign objects in the gaps of the sole, effectively avoiding poor cleaning results caused by insufficient contact between the cleaning surface and the shoe. On the other hand, the cleaning wheel 7 can also cushion the impact of stepping during the elastic deformation process, reducing the harshness when the passenger's foot contacts the cleaning wheel 7 and improving the comfort of stepping.

[0073] Meanwhile, when an occupant steps on the cleaning wheel 7, even with significant pressure, the sole of the shoe deforms and descends with the cleaning wheel 7 until it contacts the pedal body 1, where it is blocked and cannot move further downwards. This effectively prevents excessive pressure from being transmitted to components such as the first motor 3 and the transmission rod 4, thus avoiding damage to these components. The cleaning wheel 7 can utilize a conventional structure with existing brushes or textures, which will not be described in detail here.

[0074] In some exemplary embodiments, the pedal body 1 is provided with a second drive unit, which is disposed corresponding to the cleaning wheel 7 and is used to output rotational power. Furthermore, a connecting part is provided between the power shaft 801 of the second drive unit and the rotation shaft 701 of the cleaning wheel 7, which can connect the cleaning wheel 7 and the second drive unit to drive the cleaning wheel 7 to rotate.

[0075] As designed above, the rotational power output from the second drive unit is transmitted to the cleaning wheel 7 via the connecting part, enabling the cleaning wheel 7 to actively rotate when in use (extending above the pedal body 1). Compared to passive friction cleaning achieved solely by the rider stepping on the wheel, the actively rotating cleaning wheel 7 generates stronger brushing force through its circular motion, quickly removing foreign objects from the soles of shoes. Simultaneously, it rapidly flings the cleaned-up objects off the surface of the cleaning wheel 7, preventing them from re-adhering to the soles or the cleaning wheel 7, thus achieving a better cleaning effect.

[0076] In addition, the cleaning wheel 7 needs to perform two independent movements: first, it slides up and down to switch between the usage state (extended) and the storage state (retracted); second, it rotates to perform active cleaning in the usage state. If the connecting part remains connected, the power shaft 801 of the second drive unit will restrict the up and down movement of the cleaning wheel 7 through a rigid connection (e.g., the power shaft 801 cannot rise and fall synchronously with the cleaning wheel 7), causing the two movements to interfere with each other.

[0077] At this time, the connecting part is made to connect to the second drive unit only when the cleaning wheel 7 is in use (extending out of the pedal body 1), and automatically disconnect when it is in the storage state (received in the pedal body 1). Thus, when the cleaning wheel 7 slides up and down to switch states, the connecting part can be disconnected, allowing the cleaning wheel 7 to be freed from the constraint of the second drive unit and freely move up and down along the guide groove 1012 of the pedal body 1, ensuring smooth and uninterrupted state switching.

[0078] When the cleaning wheel 7 reaches the preset position for use, the connecting part automatically engages, transmitting the rotational power of the second drive unit to the cleaning wheel 7, enabling it to rotate and clean. This ensures that the two movements of the cleaning wheel 7 do not interfere with each other, thus achieving a complete realization of the cleaning wheel 7's function.

[0079] Combination Figure 17 and Figure 22 As shown, in a specific implementation, the second drive unit in this embodiment can be a second motor 8 mounted on the pedal body 1. This second motor 8 can output rotational power to drive the cleaning wheel 7 to rotate. Moreover, as... Figure 17 As shown, the second motor 8 is specifically screwed onto the side plate portion of the plate 101.

[0080] In some exemplary embodiments, the connecting part includes a slot 8011 located at the end of the drive shaft 801 and an insert block located at the end of the rotating shaft 701. The slot 8011 has a notch at its bottom, through which the insert block can be inserted and rotated synchronously with the drive shaft 801. In this structure, when the insert block is inserted into the slot 8011 through the notch, its outer periphery fits tightly against the inner wall of the slot 8011, restricting relative rotation between them. Thus, the torque of the second drive shaft 801 can be transmitted to the rotating shaft 701 of the cleaning wheel 7, thereby driving the cleaning wheel 7 to rotate.

[0081] Furthermore, when the cleaning wheel 7 descends from its active state to its retracted state, the insert can directly disengage from the notch in the vertical direction, automatically disconnecting the connection without requiring additional drive components. This design effectively accommodates the vertical movement of the cleaning wheel 7, preventing interference from the connection on its trajectory and ensuring a smooth, unobstructed transition between states.

[0082] In specific implementation, it can be as follows: Figure 12 As shown, the slot 8011 is rectangular and has two opposing planes. Correspondingly, the rotating shaft 701 on the cleaning wheel 7 has a limiting surface adapted to the two planes. In addition, the notch on the power shaft 801 extends vertically along the power shaft 801 of the second motor 8. Thus, when the cleaning wheel 7 rises from bottom to top to a preset position, the insert can be inserted into the slot 8011, and the relative rotation of the two is restricted by the contact between the limiting surface and the plane. Therefore, when the power shaft 801 of the second motor 8 rotates, the cleaning wheel 7 can be driven to rotate.

[0083] It is worth noting that, regarding the pedal structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 22 As shown, it may include, for example, a pedal body 1 with a cleaning port K on the top, a first drive part and a cleaning part, a second drive part, a shielding part that is tractively connected to the first drive part, and a transmission part disposed between the shielding part and the cleaning part.

[0084] The cover plate 2 is connected to the first drive unit via a transmission rod 4, and both ends of the transmission rod 4 are hinged to the drive shafts of the cover plate 2 and the first drive unit, respectively. The cleaning unit includes a cleaning wheel 7 that slides on the pedal body 1 in the vertical direction. The transmission unit includes a rack portion 202 on the cover plate 2 and a drive rod 5 that is rotatably mounted on the pedal body 1. The cleaning unit includes the cleaning wheel 7 that is connected to the drive rod 5.

[0085] The rack portion 202 extends along the power output direction of the first drive unit, and one end of the drive rod 5 is provided with a toothed portion 501 that meshes with the rack portion 202. The cover plate 2 can drive the drive rod 5 to rotate through the toothed portion 501 and drive the cleaning wheel 7 to move.

[0086] The second drive unit is provided corresponding to the cleaning wheel 7 and is used to output rotational power. A connecting part is provided between the power shaft 801 of the second drive unit and the rotating shaft 701 of the cleaning wheel 7. The connecting part can connect the cleaning wheel 7 in use with the second drive unit to drive the cleaning wheel 7 to rotate.

[0087] In the preferred embodiment of the above pedal structure, the specific configuration and arrangement of the pedal body 1, the shielding part, the cleaning part and the transmission part, etc., can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the pedal body 1, the shielding part, the cleaning part and the transmission part, etc., can also be referred to the description in the above exemplary embodiments.

[0088] The pedal structure of this embodiment, in practical use, is combined with... Figures 10 to 14 As shown, when the user triggers the side pedal operation (such as opening the car door), the first motor 3 starts and drives the cover plate 2 to slide along the slide groove 1011 of the pedal body 1, so that the cover plate 2 switches from a first state of blocking the cleaning port K to a second state of being housed in the pedal body 1. During this process, the cover plate 2 engages with the toothed portion 501 of the drive rod 5 through the rack portion 202, driving the drive rod 5 to rotate, and then through the hinged transmission of the driven rod 6, causing the cleaning wheel 7 to slide in the up and down direction, and finally extend from the housed state in the pedal body 1 to the top, entering the use state.

[0089] Meanwhile, as the cleaning wheel 7 switches from the storage state to the use state, the insert at the end of the shaft 701 of the cleaning wheel 7 automatically slides into the slot 8011 along the notch at the bottom of the slot 8011 of the power shaft 801 of the second motor 8, so that the insert fits tightly with the slot 8011, realizing the synchronous rotation connection between the shaft 701 of the cleaning wheel 7 and the power shaft 801 of the second motor 8, and completing the preparation for power transmission.

[0090] Then, the second motor 8 outputs rotational power, which is transmitted to the cleaning wheel 7 via the slot 8011 and the insert block, driving the cleaning wheel 7 to rotate actively. Through the surface cleaning structure (which penetrates deep into the sole's tread to remove mud, dust, and other foreign objects, while simultaneously using centrifugal force to fling the foreign objects off the surface of the cleaning wheel 7, preventing secondary adhesion), the cleaning wheel 7, made of elastic material, undergoes adaptive deformation when the user steps on it. This further conforms to the contour of the sole, increasing the contact area between the cleaning structure and the sole, and improving the removal of stubborn foreign objects. Simultaneously, the pedal body 1 prevents the sole from excessively protruding, avoiding overload pressure on the power shaft 801 of the second motor 8.

[0091] After cleaning is completed, the first motor 3 drives the cover plate 2 in the reverse direction to reset. The cover plate 2 slides back to the first state along the slide groove 1011, covering the cleaning opening K again. During this process, the driving rod 5 rotates in the reverse direction with the rack part 202, and drives the cleaning wheel 7 to retract into the pedal body 1 in the up and down direction via the driven rod 6, returning to the storage state. At the same time, the insert on the rotating shaft 701 of the cleaning wheel 7 axially disengages along the notch of the slot 8011, disconnecting from the power shaft 801 of the second motor 8. The second motor 8 stops power output, thus achieving the covering of the cleaning opening K by the cover plate 2 and the storage of the cleaning wheel 7 in the pedal body 1, which makes the pedal body 1 have a better sense of integrity and refinement.

[0092] The pedal structure of this embodiment, through its design, not only enables the pedal body 1 to support passengers getting in and out of the vehicle, but also allows the cover plate 2 to slide and trigger the extension of the cleaning wheel 7. In conjunction with the second motor 8, the cleaning wheel 7 is driven to rotate actively, which can effectively remove foreign objects from the soles of shoes. This effectively solves the problem of the traditional side pedals having poor functionality as they only provide support, and can effectively solve the problem of cabin pollution, reducing cleaning frequency and maintenance costs from the source.

[0093] An embodiment of the second aspect of this application provides a vehicle having the pedal structure described above.

[0094] In specific implementation, the first motor 3 and the second motor 8 can be designed to connect electronically with the car key / mobile app. This allows the user to press the "start" button via the mobile app or car key without being near the vehicle. The trigger then sends an "electronic start signal" to the control module via radio frequency (car key) or mobile network / Bluetooth (mobile app). Upon receiving the signal, the control module (vehicle controller) sends a "forward rotation start command" to the first motor 3, activating it to hide the cover 2 and drive the cleaning wheel 7 to rise into its operational state.

[0095] At this time, the control module can record the number of rotations through the encoder of the first motor 3 and calculate the upward stroke of the cleaning wheel 7. When the control module receives the "cleaning wheel 7 in position signal", it immediately sends a "stop command" to the first motor 3, and the first motor 3 is powered off and stops running. At the same time, it sends a "rotation start command" to the second motor 8, and the second motor 8 starts and drives the cleaning wheel 7 to rotate (power is transmitted through the rigid engagement of the socket and slot 8011), entering the "cleaning ready state", waiting for the user to step on it for cleaning.

[0096] After receiving the "cleaning wheel 7 in position signal", the control module immediately sends a "stop command" to the first motor 3, and the first motor 3 is powered off and stops running. At the same time, it sends a "rotation start command" to the second motor 8, and the second motor 8 starts and drives the cleaning wheel 7 to rotate (power is transmitted through the rigid engagement of the insert and slot 8011), and the pedal structure enters the "cleaning ready state", waiting for the user to step on it for cleaning.

[0097] When the user presses the "off button" on the car key or mobile app, the trigger sends an "electronic off signal" to the control module. The control module first sends a "disconnect command" to the second motor 8 to stop the second motor 8 from running. After detecting that the second motor 8 has stopped, the control module sends a "reverse start command" to the first motor 3. The first motor 3 reverses and drives the cover plate 2 to slide in the opposite direction along the slide groove 1011, switching from the "receiving state" to the "sliding out and blocking the cleaning port K" state. Simultaneously, the cleaning wheel 7 is driven to descend vertically through the transmission mechanism.

[0098] When the cleaning wheel 7 descends to the lowest point (retraction endpoint) within the pedal body 1, the transmission mechanism triggers a separation signal, meaning the rack portion 202 on the cover plate 2 disengages from the tooth portion 501. The cleaning wheel 7 loses its power source, stops descending, and remains in the retracted state. The control module controls the cover plate 2 to completely cover the cleaning opening K (the position is confirmed by the encoder of the first motor 3). At this point, the control module sends a "stop command" to the first motor 3, the first motor 3 is de-energized, and the entire closing process is completed.

[0099] The vehicle in this embodiment, by setting up the pedal structure as described above, can clean the soles of the shoes of the driver and passengers, effectively maintaining the cleanliness of the cabin and improving the overall quality.

[0100] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
