[0038] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0039] For the sake of convenience, in the description of the embodiment of the present disclosure, the front and rear directions refer to the front and rear directions of the vehicle after the pedal is installed on the vehicle body, wherein the direction toward the inside of the vehicle body after the pedal is installed on the vehicle body is called inside, and the direction toward the outside of the vehicle body is called outside.

[0040] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0041] The present disclosure is based on the inventors' findings and understanding of the following facts and problems:

[0042] In the related art, footrests installed on vehicles are usually fixed, with a fixed height from the ground, which makes them less practical and convenient. In addition, related art proposes installing retractable footrests on vehicles, which extend from under the vehicle when in use and retract when not in use.

[0043] The inventors recognized that for vehicles with high ground clearance, fixed and telescopic steps still present the problem of being too tall and inconvenient to use. To address this, related art proposes installing both fixed and telescopic steps on a vehicle. When the telescopic step is extended, it forms a two-stepped step with the fixed step, thereby improving ease of use and adaptability to different vehicles. However, in related art, the fixed and telescopic steps are separately installed under the vehicle, resulting in a complex installation structure and time-consuming and labor-intensive assembly and disassembly. Furthermore, the limited space under the vehicle chassis further increases the difficulty of installing the fixed and telescopic steps. Furthermore, when the telescopic step is retracted, it is located entirely under the vehicle, adversely affecting the vehicle's passability.

[0044] In addition, in the related art, the number of telescopic pedals installed on the vehicle is pre-fixed, and the interface of the control system of the telescopic foot pedal is the same as the number of telescopic foot pedals. When the user wants to increase the number of telescopic pedals, for example, when the user wants to add a telescopic pedal at the tailgate of the vehicle, the entire control system needs to be replaced, resulting in high cost, unchanged modification, and poor user experience.

[0045] The present disclosure solves at least one of the above technical problems to a certain extent.

[0046] 1 to 30 , the foot pedal device 10 according to the embodiment of the present disclosure includes a mounting frame 51 , a fixed pedal 31 , a telescopic mechanism 12 , and a telescopic pedal 11 . The fixed pedal 31 is mounted on the mounting frame 51 .

[0047] The telescopic mechanism 12 is mounted to one of the mounting frame 51 and the fixed step 31. The telescopic step 11 is mounted on the telescopic mechanism 12 so that the telescopic mechanism 12 drives the telescopic step 11 to move between an extended position and a retracted position. In the extended position, at least a portion of the telescopic step 11 extends outward from below the fixed step 31, so that the telescopic step 11 and the fixed step 31 form a two-step step. In the retracted position, the telescopic step 11 is retracted below the fixed step 31.

[0048] The foot pedal device 10 of the embodiment of the present disclosure can be assembled into a whole by installing both the fixed pedal 31 and the telescopic mechanism 12 on the mounting frame 51, or by installing the telescopic mechanism 12 on the fixed pedal 31 and the fixed pedal 31 on the mounting frame 51, so that the foot pedal device 10 can be installed or removed as a whole only by installing the mounting frame 51 on the vehicle body 21 or removing it from the vehicle body 21.

[0049] That is, the fixed pedal 31, the telescopic pedal 11, the telescopic mechanism 12, and the mounting bracket 51 can be assembled together before the foot step device 10 is mounted on the vehicle body 21 of the vehicle 1. This can reduce the difficulty of mounting and removing the foot step device 10 from the vehicle body 21 and improve the efficiency of mounting and removing the foot step device 10 from the vehicle body 21.

[0050] Furthermore, by retracting the entirety or at least a substantial portion of the telescopic step 11 below the fixed step 31, rather than beneath the vehicle body 21, or at least by not retracting the entirety of the telescopic step 11 below the vehicle body 21, the telescopic step 11 does not significantly occupy the space between the chassis of the vehicle 1 and the ground. This maintains the distance between the chassis of the vehicle 1 and the ground, thereby ensuring the vehicle's passability. In the extended position, the fixed and telescopic steps form a multi-step system, which is particularly advantageous for vehicles with high ground clearance, thus offering excellent applicability and a wide range of uses.

[0051] Therefore, the foot pedal device 10 of the embodiment of the present disclosure has the advantages of compact structure, low difficulty in installation and disassembly, and high efficiency in installation and disassembly.

[0052] As shown in Figures 1-30, the vehicle 1 of the present embodiment includes a vehicle body 21, doors, and a foot pedal device 10. The doors include a left front door 221, a left rear door 222, a right front door (not shown), a right rear door (not shown), and a tailgate (not shown). The driver can enter and exit the cab through the left front door 221, and the driver can also enter and exit the cab through the right front door. The mounting bracket 51 of the foot pedal device 10 is mounted on the vehicle body 21.

[0053] The footrest device 10 includes a mounting frame 51, a fixed pedal 31, a telescopic pedal 11, and a telescopic mechanism 12. The mounting frame 51 can be mounted on the vehicle body 21.

[0054] As shown in Figures 1 to 3 and Figures 6 to 11, the mounting bracket 51 includes a first side plate 511, a second side plate 512, an outer crossbeam 513, an inner crossbeam 514, and a middle crossbeam 515. The first side plate 511 and the second side plate 512 are spaced apart from each other along the length of the fixed pedal 31, that is, the first side plate 511 and the second side plate 512 are spaced apart from each other along the length of the vehicle body 21.

[0055] The first end of the outer crossbeam 513 is connected to the first side panel 511, and the second end of the outer crossbeam 513 is connected to the second side panel 512. The first end of the inner crossbeam 514 is connected to the first side panel 511, and the second end of the inner crossbeam 514 is connected to the second side panel 512. The first end of the middle crossbeam 515 is connected to the first side panel 511, and the second end of the middle crossbeam 515 is connected to the second side panel 512. In other words, the first side panel 511 and the second side panel 512 are connected together by each of the outer crossbeam 513, the inner crossbeam 514, and the middle crossbeam 515.

[0056] The inner crossbeam 514 is located inside the outer crossbeam 513, and the intermediate crossbeam 515 is located between the inner crossbeam 514 and the outer crossbeam 513. The fixed pedal 31 is connected to the outer crossbeam 513 and the intermediate crossbeam 515 via connectors, and the telescopic mechanism 12 is also connected to the inner crossbeam 514 and the outer crossbeam 513 via connectors. This allows the fixed pedal 31 and the telescopic mechanism 12 to be more securely mounted on the mounting bracket 51.

[0057] The inner cross beam 514 is a flat inner cross plate. In other words, the inner cross beam 514 is generally plate-shaped and is arranged horizontally, that is, the thickness direction of the inner cross beam 514 is consistent with the up-down direction.

[0058] The outer crossbeam 513 includes a horizontal first outer cross plate 5131 and an upright second outer cross plate 5132. In other words, each of the first and second outer cross plates 5131, 5132, is generally plate-shaped. The first outer cross plate 5131 is horizontally disposed, i.e., its thickness aligns with the vertical direction. The second outer cross plate 5132 is vertically disposed, i.e., its thickness aligns with the horizontal direction. The upper edge of the second outer cross plate 5132 abuts the first outer cross plate 5131.

[0059] The intermediate crossbeam 515 includes an upright first intermediate cross plate 5151 and an upright second intermediate cross plate 5152. Specifically, each of the first intermediate cross plate 5151 and the second intermediate cross plate 5152 is generally plate-shaped and disposed vertically. Specifically, the thickness of the first intermediate cross plate 5151 aligns with the horizontal direction, while the thickness of the second intermediate cross plate 5152 aligns with the horizontal direction. The first intermediate cross plate 5151 and the second intermediate cross plate 5152 are spaced apart in the inward-outward direction.

[0060] The fixed pedal 31 is connected to the first outer transverse plate 5131 and the first intermediate transverse plate 5151, while the telescopic mechanism 12 is connected to the inner transverse plate (inner beam 514) and the second outer transverse plate 5132. The lower surface of the inner transverse plate is higher than the upper surface of the first outer transverse plate 5131. The connection points between the fixed pedal 31, the first intermediate transverse plate 5151, and the second intermediate transverse plate 5152 are higher than the upper surface of the first outer transverse plate 5131. This makes the structure of the mounting frame 51 and the footrest device 10 more rational.

[0061] As shown in Figures 1-3 and 6-11, the mounting bracket 121 of the telescopic mechanism 12 includes a first horizontal plate 1211, a first vertical plate 1212, a third side plate 1213, and a fourth side plate 1214. The third side plate 1213 and the fourth side plate 1214 are spaced apart from each other along the length of the fixed pedal 31. In other words, the third side plate 1213 and the fourth side plate 1214 are spaced apart from each other along the length of the vehicle body 21.

[0062] The first end of the first horizontal plate 1211 is connected to the third side plate 1213, the second end of the first horizontal plate 1211 is connected to the fourth side plate 1214, the first end of the first vertical plate 1212 is connected to the third side plate 1213, and the second end of the first vertical plate 1212 is connected to the fourth side plate 1214. In other words, the third side plate 1213 and the fourth side plate 1214 are connected together through each of the first horizontal plate 1211 and the first vertical plate 1212.

[0063] The first horizontal plate 1211 and the inner beam 514 are connected by bolts. Specifically, the first horizontal plate 1211 has a first through hole, and the inner beam 514 has a second through hole. The bolts pass through the first through hole and the second through hole to connect the first horizontal plate 1211 and the inner beam 514.

[0064] The first vertical plate 1212 and the second outer horizontal plate 5132 are connected by bolts. Specifically, the first vertical plate 1212 has two third through holes, and the second outer horizontal plate 5132 has two fourth through holes. One bolt passes through one of the third through holes and one of the fourth through holes to connect the first vertical plate 1212 and the second outer horizontal plate 5132, and another bolt passes through the other third through hole and the other fourth through hole to connect the first vertical plate 1212 and the second outer horizontal plate 5132.

[0065] Optionally, the distance between one of the third through holes and the third side plate 1213 in the length direction of the fixed pedal 31 is substantially equal to the distance between the other of the third through holes and the fourth side plate 1214 in the length direction of the fixed pedal 31. For example, the third side plate 1213 and the fourth side plate 1214 are symmetrically arranged relative to the first straight line (the first vertical plane), and the two third through holes are also symmetrically arranged relative to the first straight line (the first vertical plane).

[0066] One of the fourth through holes is adjacent to the first side plate 511 in the length direction of the fixed pedal 31, and the distance between the other fourth through hole and the first side plate 511 in the length direction of the fixed pedal 31 is substantially equal to the distance between the other fourth through hole and the second side plate 512 in the length direction of the fixed pedal 31. In other words, the other fourth through hole is substantially located between the first side plate 511 and the second side plate 512.

[0067] As shown in Figures 1-2 and 12-13, the telescopic mechanism 12 includes a mounting bracket 121, a pedal bracket 122, and an arm assembly connected between the mounting bracket 121 and the pedal bracket 122. The mounting frame 51 has a mounting groove 516, and at least a portion of the mounting bracket 121 is received in the mounting groove 516. This makes the structure of the footrest device 10 more compact.

[0068] As shown in Figures 1-2, 8-9 and 12-13, the fixed pedal 31 includes a frame 313, a support plate 314 and a plate rack 315. The frame 313 is composed of an inner tube 3131, an outer tube 3132, an end tube 3133 and a reinforcement tube 3134. The support plate 314 is installed on the frame 313, the plate rack 315 is installed under the frame 313, and the reinforcement tube 3134 is connected between the inner tube 3131 and the outer tube 3132.

[0069] The length of the inner tube 3131 coincides with the length of the vehicle body 21, and the length of the outer tube 3132 coincides with the length of the vehicle body 21. Multiple reinforcement tubes 3134 are provided, spaced apart along the length of the inner tube 3131 (outer tube 3132). The inner end of each reinforcement tube 3134 is connected to the inner tube 3131, and the outer end of each reinforcement tube 3134 is connected to the outer tube 3132.

[0070] The inner tube 3131 has a fifth through hole, and the first intermediate transverse plate 5151 has a sixth through hole. Bolts pass through the fifth and sixth through holes to connect the inner tube 3131 and the first intermediate transverse plate 5151. The second intermediate transverse plate 5152 has a through hole opposite the sixth through hole, allowing the bolt to pass through the second intermediate transverse plate 5152. The reinforcement tube 3134 has a seventh through hole, and the first outer transverse plate 5131 has an eighth through hole. Bolts pass through the seventh and eighth through holes to connect the reinforcement tube 3134 and the first outer transverse plate 5131.

[0071] As shown in Figures 6 and 7, the vehicle body 21 includes a second horizontal plate 211 and a second vertical plate 212. The inner crossbeam 514 of the mounting bracket 51 is connected to the second horizontal plate 211. Optionally, the second horizontal plate 211, the inner crossbeam 514, and the first horizontal plate 1211 are connected by a common connector. The second vertical plate 212 is connected to the second intermediate cross plate 5152. This allows the mounting bracket 51 to be more securely mounted on the vehicle body 21.

[0072] As shown in Figures 1, 2, 4, 5, 8, and 9, the fixed pedal 31 is provided with a receiving groove 311, the mounting bracket 51 is mounted within the receiving groove 311, and the telescopic mechanism 12 is mounted within the receiving groove 311. In the retracted position, the entire telescopic pedal 11, or a portion thereof, is accommodated within the receiving groove 311. This protects the telescopic pedal 11 by preventing foreign matter such as sand and gravel from entering the gap between the telescopic pedal 11 and the fixed pedal 31, thereby preventing damage to the telescopic pedal 11 from such foreign matter. This improves the service life of the telescopic pedal 11 and the foot pedal assembly 10. Furthermore, the foot pedal assembly 10 can be made more compact.

[0073] Optionally, in the retracted position, at least a portion of the surface of the telescopic pedal 11 is flush with the surface of the fixed pedal 31. This allows the accommodating groove 311 to better protect the telescopic pedal 11, further extending the service life of the telescopic pedal 11 and the foot pedal device 10, and making the structure of the foot pedal device 10 more compact.

[0074] The bottom surface of the fixed pedal 31 includes a first inclined surface 3122 that slopes downward from the outside to the inside. The bottom surface 111 of the telescopic pedal 11 includes a first flat surface 1111 that is horizontal in the extended position and a second inclined surface 1112 that slopes downward from the outside to the inside. In other words, the bottom surface 111 of the telescopic pedal 11 includes the first flat surface 1111 and the second inclined surface 1112. When the telescopic pedal 11 is in the extended position, the first flat surface 1111 is horizontal, i.e., the first flat surface 1111 is horizontal, while the second inclined surface 1112 is inclined. When the telescopic pedal 11 is in the extended position, the inner edge of the second inclined surface 1112 is connected to the outer edge of the first flat surface 1111, and the inner edge of the second inclined surface 1112 is located below the outer edge of the second inclined surface 1112.

[0075] In the retracted position, the second inclined surface 1112 is flush with the first inclined surface 3122, and the outer side surface 112 of the telescopic pedal 11 faces the outer wall 3111 of the receiving groove 311. This allows the receiving groove 311 to better protect the telescopic pedal 11, further increasing the service life of the telescopic pedal 11 and the footrest device 10.

[0076] Optionally, in the retracted position, the gap between the outer side surface 112 of the telescopic pedal 11 and the outer wall 3111 of the receiving groove 311 is greater than or equal to zero and less than or equal to 5 mm. This further prevents foreign matter such as sand and gravel from entering the receiving groove 311, that is, further prevents foreign matter such as sand and gravel from entering between the fixed pedal 31 and the telescopic pedal 11 in the retracted position, thereby better protecting the telescopic pedal 11 and further extending the service life of the telescopic pedal 11 and the footrest device 10.

[0077] Each telescopic pedal 11 is mounted on a corresponding telescopic mechanism 12. The pedal device 10 further includes a motor 13 connected to the corresponding telescopic mechanism 12. The motor 13 is used to drive the corresponding telescopic mechanism 12 to drive the corresponding telescopic pedal 11 to move between an extended position and a retracted position.

[0078] Optionally, the motor 13 is a brushless motor. The brushless motor has the advantages of small size, simple control program, precise position and speed control of the telescopic pedal 11, small impact, etc., and can make the telescopic pedal 11 stop at any position between the extended position and the retracted position.

[0079] Optionally, the entire fixed pedal 31 is located outside the vehicle body 21. Alternatively, the distance between the innermost point of the fixed pedal 31 and the outer side of the vehicle body 21 is less than 20 mm, that is, the distance between the innermost point of the fixed pedal 31 and the outer side of the vehicle body 21 in the inward-outward direction is less than 20 mm. This allows the entire or a majority of the fixed pedal 31 to be located outside the vehicle body 21, making it easier for users to board and exit the vehicle by stepping on the fixed pedal 31.

[0080] Optionally, in the retracted position, the entire telescopic step 11 is located outside the vehicle body 21. Alternatively, the distance between the innermost point of the telescopic step 11 and the outer side of the vehicle body 21 is less than 30 mm, that is, the distance between the innermost point of the telescopic step 11 and the outer side of the vehicle body 21 in the inward-outward direction is less than 30 mm. Thus, when the telescopic step 11 moves from the retracted position to the extended position, it can extend a greater distance outward from the vehicle body 21, making it easier for users to board and exit the vehicle by stepping on the telescopic step 11.

[0081] In some examples, the foot pedal device 10 also includes a controller 14, which has a plurality of interfaces 141. The telescopic pedal device includes at least one telescopic pedal 11, and each telescopic pedal 11 is mounted on a corresponding telescopic mechanism 12. The motor 13 corresponds one-to-one to the telescopic mechanism 12. Each motor 13 is connected to the corresponding telescopic mechanism 12 to drive the corresponding telescopic mechanism 12 to drive the corresponding telescopic pedal 11 to move between an extended position and a retracted position. In other words, the motor 13 can drive the telescopic pedal 11 mounted on the telescopic mechanism 12 to extend and retract through the corresponding telescopic mechanism 12. The number of interfaces 141 is greater than the number of telescopic pedals 11, and one motor 13 that drives one telescopic mechanism 12 corresponding to each telescopic pedal 11 is connected to one interface 141.

[0082] In other examples, the foot pedal device 10 further includes a controller 14, which has a plurality of interfaces 141. The telescopic pedal device includes at least one telescopic pedal 11, and each telescopic pedal 11 is mounted on a corresponding plurality of telescopic mechanisms 12. The motor 13 corresponds one-to-one to the telescopic mechanism 12. Each motor 13 is connected to the corresponding telescopic mechanism 12 to drive the corresponding telescopic mechanism 12 to drive the corresponding telescopic pedal 11 to move between an extended position and a retracted position. In other words, the motor 13 can drive the telescopic pedal 11 mounted on the telescopic mechanism 12 to extend and retract through the corresponding telescopic mechanism 12. The number of interfaces 141 is greater than the number of telescopic pedals 11, and the multiple motors 13 that drive the multiple telescopic mechanisms 12 corresponding to the same telescopic pedal 11 are connected to the same interface 141.

[0083] The foot pedal device of the disclosed embodiment utilizes a controller with multiple interfaces, where the number of interfaces exceeds the number of telescopic pedals. This allows a single controller to control at least one telescopic pedal. This reduces the cost of the controller and foot pedal device, saves space for the controller, simplifies controller installation, and improves the integration of the foot pedal device.

[0084] Because the number of interfaces exceeds the number of telescopic pedals, users can add additional telescopic pedals without installing a new controller. In other words, the controller has a reserved interface for connecting the motor that drives the additional telescopic pedals, making it easy for users to adjust the number of telescopic pedals as needed. Furthermore, when the footrest device is used on different vehicle models, users can add or reduce the number of telescopic pedals according to the vehicle model without installing a new controller or removing an existing one.

[0085] In the present disclosure, "the number of the interfaces is greater than the number of the telescopic pedals" means that the number of interfaces of the controller is greater than the number of telescopic pedals that the foot pedal device initially has, so that the redundant interfaces can be used as reserved interfaces, thereby expanding the number of telescopic pedals of the foot pedal device. It is understandable that after the number of telescopic pedals is subsequently expanded, the number of interfaces can be equal to the number of telescopic pedals. For example, the foot pedal device is sold from the factory or the vehicle manufacturer installs the foot pedal device on the vehicle with two telescopic pedals, and the controller has three interfaces, one of which is used as a reserved interface. When the user or the vehicle manufacturer subsequently expands the number of telescopic pedals of the foot pedal device to three according to customer requirements, the motor that drives the additional telescopic pedal is connected to the reserved interface. The specific difference between the number of interfaces and the number of telescopic pedals can be set according to specific needs. Preferably, the number of interfaces is set to be greater than or equal to the maximum number of telescopic pedals that can be installed on the vehicle.

[0086] Therefore, the foot pedal device of the embodiment of the present disclosure has the advantages of low cost, low installation difficulty, high integration, wide application range, and applicability to various vehicle models.

[0087] Optionally, the fixed pedal 31 has multiple mounting positions, the number of which is greater than the number of the telescopic mechanism 12, that is, the number of mounting positions is greater than the number of the telescopic pedals 11. Thus, the fixed pedal 31 has the reserved mounting positions, which makes it easier to add the telescopic mechanism 12 and the telescopic pedal 11.

[0088] Each telescopic step 11 is mounted on a corresponding telescopic mechanism 12. As shown in FIG24 , the number of telescopic mechanisms 12 can be equal to the number of telescopic steps 11. In other words, each telescopic step 11 can be mounted on a telescopic mechanism 12. If there are multiple telescopic steps 11, the multiple telescopic steps 11 are mounted on the multiple telescopic mechanisms 12 in a one-to-one correspondence.

[0089] As shown in Figure 25, the number of telescopic mechanisms 12 can be N times the number of telescopic pedals 11, where N is a positive integer greater than or equal to 2. That is, the number of telescopic pedals 11 is M, and the number of telescopic mechanisms 12 is N times M. Each telescopic pedal 11 can be installed on N telescopic mechanisms 12, that is, N telescopic mechanisms 12 drive the same telescopic pedal 11 to move between an extended position and a retracted position. Preferably, as shown in Figure 25, one telescopic pedal 11 is installed on two telescopic mechanisms 12. In other words, one telescopic pedal 11 is installed on a first telescopic mechanism 12-1 and a second telescopic mechanism 12-2, the first telescopic mechanism 12-1 is driven by a first motor 31-1, and the second telescopic mechanism 12-2 is driven by a second motor 13-2.

[0090] As shown in Figures 24 and 25 , the motors 13 correspond one to one with the telescopic mechanisms 12. Each motor 13 is connected to a corresponding telescopic mechanism 12 to drive the corresponding telescopic mechanism 12, thereby driving the corresponding telescopic pedal 11 to move between an extended position and a retracted position. In other words, the motor 13 can drive the telescopic pedal 11 mounted on the telescopic mechanism 12 to move between an extended position and a retracted position via the corresponding telescopic mechanism 12.

[0091] As shown in Figures 26 to 29, the controller 14 has multiple interfaces 141. The number of interfaces 141 is greater than the number of telescopic pedals 11. The motor 13 that drives the telescopic mechanism 12 corresponding to the same telescopic pedal 11 is connected to the same interface 141.

[0092] As shown in FIG. 24 , each telescopic pedal 11 is mounted on a telescopic mechanism 12 , and a motor 13 driving a telescopic mechanism 12 is connected to an interface 141 .

[0093] As shown in Figure 26, the controller 14 has three interfaces: a first interface 14-1, a second interface 14-2, and a third interface 14-3. The footrest device 10 has two telescopic pedals: a first telescopic pedal 11-1 and a second telescopic pedal 11-2. For example, the first telescopic pedal 11-1 can correspond to the two left doors of the vehicle 1, and the second telescopic pedal 11-2 can correspond to the two right doors of the vehicle 1. The first telescopic pedal 11-1 is driven by a first telescopic mechanism 12-1, which is driven by a first motor 13-1. The second telescopic pedal 11-2 is driven by a second telescopic mechanism 12-2, which is driven by a second motor 13-2. The third interface 14-3 is a backup interface. For example, if the user later wants to install a telescopic pedal on the tailgate of the vehicle 1, they only need to connect the motor used to drive the telescopic mechanism of the telescopic pedal on the tailgate to the third interface 14-3, without having to replace the controller and control system. When the user wants to remove a telescopic pedal later, he only needs to disconnect the motor of the telescopic pedal from the corresponding interface and remove the telescopic mechanism and the telescopic pedal from the vehicle body 21.

[0094] Each telescopic step 11 can be mounted on multiple telescopic mechanisms 12. That is, one telescopic step 11 is driven by multiple telescopic mechanisms 12, and the multiple motors 13 driving the multiple telescopic mechanisms 12 are connected to the same interface 141. For example, as shown in FIG25 , each telescopic step 11 is mounted on two telescopic mechanisms 12, and the two motors 13 driving the two telescopic mechanisms 12 are connected to the same interface 141.

[0095] As shown in Figure 27, the foot pedal device 10 includes a first telescopic pedal 11-1 and a second telescopic pedal 11-2. The controller 14 has a first interface 14-1, a second interface 14-2, and a third interface 14-3, with the third interface 14-3 serving as a backup interface. The first telescopic pedal 11-1 is driven by the first telescopic mechanism 12-1A No. 1 and the first telescopic mechanism 12-1B No. 2. The first telescopic mechanism 12-1A No. 1 is driven by the first motor 13-1A No. 1, and the first telescopic mechanism 12-1B No. 2 is driven by the first motor 13-1B No. 2. The first motor 13-1A No. 1 and the first motor 13-1B No. 2 are connected to the first interface 14-1.

[0096] Similarly, the second telescopic pedal 11-2 is driven by the first second telescopic mechanism 12-2A and the second telescopic mechanism 12-2B. The first second telescopic mechanism 12-2A is driven by the first second motor 13-2A, and the second second telescopic mechanism 12-2B is driven by the second second motor 13-2B. The first second motor 13-2A ​​and the second second motor 13-2B are connected to the second interface 14-2.

[0097] As shown in FIG28 , the embodiment shown in FIG28 differs from the embodiment shown in FIG27 in that a third telescopic step 11-3 is provided on the vehicle's tailgate. The third telescopic step 11-3 is driven by a third telescopic mechanism 12-3, which is driven by a third motor 13-3. The third motor 13-3 is connected to a third interface 14-3. If the user subsequently removes the tailgate telescopic step, they simply disconnect the third motor 13-3 from the third interface 14-3 and remove the third telescopic step 11-3 and the third telescopic mechanism 12-3 from the vehicle body 21.

[0098] As shown in FIG29 , there are five interfaces 141 : a first interface 14 - 1 , a second interface 14 - 2 , a third interface 14 - 3 , a fourth interface 14 - 4 , and a fifth interface 14 - 5 , wherein the fifth interface 14 - 5 is a reserved interface.

[0099] There are four telescopic pedals 11: a first telescopic pedal 11-1, a second telescopic pedal 11-2, a third telescopic pedal 11-3, and a fourth telescopic pedal 11-4. The four telescopic pedals 11 correspond to the left front door 221, the left rear door 222, the right front door, and the right rear door respectively.

[0100] The first telescopic pedal 11-1 is installed on the first telescopic mechanism No. 1 12-1A and the first telescopic mechanism No. 2 12-1B, and the first motor No. 13-1A and the first motor No. 2 13-1B driving the first telescopic mechanism No. 1 12-1A and the first telescopic mechanism No. 2 12-1B are connected to the first interface 14-1.

[0101] The second telescopic pedal 11-2 is installed on the second telescopic mechanism No. 1 12-2A and the second telescopic mechanism No. 2 12-2B, and the second motor No. 1 13-2A ​​and the second motor No. 2 13-2B driving the second telescopic mechanism No. 1 12-2A and the second telescopic mechanism No. 2 12-2B are connected to the second interface 14-2.

[0102] The third telescopic pedal 11-3 is installed on the third telescopic mechanism No. 1 12-3A and the third telescopic mechanism No. 2 12-3B, and the third motor No. 1 13-3A and the third motor No. 2 13-3B that drive the third telescopic mechanism No. 1 12-3A and the third telescopic mechanism No. 2 12-3B are connected to the third interface 14-3.

[0103] The fourth telescopic pedal 11-4 is installed on the fourth telescopic mechanism No. 1 12-4A and the fourth telescopic mechanism No. 2 12-4B, and the fourth motor No. 1 13-4A and the fourth motor No. 2 13-4B that drive the fourth telescopic mechanism No. 1 12-4A and the fourth telescopic mechanism No. 2 12-4B are connected to the fourth interface 14-4.

[0104] Optionally, the foot pedal device 10 further includes a telescopic control switch (not shown), and the controller 14 allows or prohibits the telescopic pedal 11 from moving between the extended position and the retracted position according to the gear position of the telescopic control switch.

[0105] The telescopic control switch has a plurality of gears. The controller 14 allows a number of telescopic pedals 11 corresponding to the gear to move between the extended position and the retracted position according to the gear of the telescopic control switch.

[0106] For example, the vehicle 1 has a left door, a right door, and a tailgate. When the telescopic control switch is in gear 0, all telescopic pedals 11 are prohibited from moving; when the telescopic control switch is in gear 1, only the telescopic pedal 11 corresponding to the left door is allowed to move; when the telescopic control switch is in gear 2, only the telescopic pedals 11 corresponding to the left and right doors are allowed to move; when the telescopic control switch is in gear 3, the telescopic pedals 11 corresponding to the left, right, and tailgate are allowed to move.

[0107] For example, the vehicle 1 has a left front door 221, a left rear door 222, a right front door, a right rear door, and a tailgate. The telescopic control switch may have four gears: when the telescopic control switch is in gear 0, all telescopic steps 11 are prohibited from moving; when the telescopic control switch is in gear 1, only the telescopic steps 11 corresponding to the left front door 221 and the telescopic steps 11 corresponding to the left rear door 222 are allowed to move; when the telescopic control switch is in gear 2, only the telescopic steps 11 corresponding to the right front door and the telescopic steps 11 corresponding to the right rear door are allowed to move; when the telescopic control switch is in gear 3, the telescopic steps 11 corresponding to the left front door 221, the left rear door 222, the right front door, the right rear door, and the tailgate are allowed to move.

[0108] The telescopic control switch may also have six gears. When the telescopic control switch is in gear 0, all telescopic pedals 11 are prohibited from moving; when the telescopic control switch is in gear 1, only the telescopic pedal 11 corresponding to the left front door 221 is allowed to move; when the telescopic control switch is in gear 2, only the telescopic pedal 11 corresponding to the left front door 221 and the telescopic pedal 11 corresponding to the left rear door 222 are allowed to move; when the telescopic control switch is in gear 3, only the telescopic pedal 11 corresponding to the left front door 221, the left rear door 222 and the right front door is allowed to move; when the telescopic control switch is in gear 4, only the telescopic pedal 11 corresponding to the left front door 221, the left rear door 222, the right front door and the right rear door is allowed to move; when the telescopic control switch is in gear 5, the telescopic pedal 11 corresponding to the left front door 221, the left rear door 222, the right front door, the right rear door and the tailgate is allowed to move.

[0109] Of course, the foot pedal device 10 and the vehicle 1 of the embodiment of the present disclosure are not limited to the above control modes, and a corresponding control mode can be selected according to the user's habits.

[0110] Optionally, there are multiple telescopic pedals 11, and the multiple telescopic pedals 11 can move between the extended position and the retracted position independently of each other. In this way, only the telescopic pedals 11 corresponding to the doors where the user gets on and off the vehicle need to be extended or retracted, thereby making the structure of the footrest device 10 more reasonable.

[0111] Optionally, the vehicle door includes a left door and a right door, and the pedal assembly includes a left pedal assembly mounted on the left side of the vehicle body 21 and a right pedal assembly mounted on the right side of the vehicle body 21. The telescopic pedals 11 of the left and right pedal assemblies can independently move between an extended position and a retracted position. Alternatively, the telescopic pedals 11 of the left and right pedal assemblies can move synchronously with each other. Alternatively, the telescopic pedals 11 of the left and right pedal assemblies can move synchronously or independently with each other.

[0112] Optionally, the left door includes a left front door 221 and a left rear door 222, the fixed pedal 31 of the left pedal device is one corresponding to the left front door 221 and the left rear door 222 or two corresponding one-to-one to the left front door 221 and the left rear door 222, and the telescopic pedal 11 of the left pedal device is one corresponding to the left front door 221 and the left rear door 222 or two corresponding one-to-one to the left front door 221 and the left rear door 222.

[0113] The right side doors include the right front door and the right rear door, the fixed pedal 31 of the right side pedal device is one corresponding to the right front door and the right rear door or two corresponding one-to-one to the right front door and the right rear door, and the telescopic pedal 11 of the right side pedal device is one corresponding to the right front door and the right rear door or two corresponding one-to-one to the right front door and the right rear door.

[0114] The doors of vehicle 1 also include a tailgate, and the step assembly also includes a tail step assembly mounted at the rear of the vehicle body 21. The tail step assembly includes a fixed step 31 and a telescopic step 11 corresponding to the tailgate. Each of the telescopic steps 11 of the left, right, and tail step assemblies can independently move between an extended and retracted position. Alternatively, the telescopic steps 11 of the left and right step assemblies can move synchronously. Alternatively, the telescopic steps 11 of the left, right, and tail step assemblies can move synchronously or independently of one another.

[0115] The telescopic mechanism 12 is one of a four-link mechanism 12a (as shown in FIG. 14 ), a five-link mechanism 12b (as shown in FIG. 15 ), and a six-link mechanism 12c (as shown in FIG. 16 ).

[0116] As shown in FIG14 , the telescopic mechanism 12 is a four-bar linkage 12a, comprising a mounting support 121, a pedal support 122, and an arm assembly connected between the mounting support 121 and the pedal support 122. The mounting support 121 is mounted on the vehicle body 21 or the fixed pedal, and the telescopic pedal 11 is mounted on the pedal support 122.

[0117] The arm assembly includes a first arm 1231 and a second arm 1232. A first end 12311 of the first arm 1231 is pivotally connected to the mounting bracket 121 via a first connecting pin 1234, and a second end 12312 of the first arm 1231 is pivotally connected to the pedal bracket 122 via a second connecting pin 1236. The "first end 12311" herein refers to the upper end of the first arm 1231 as shown in FIG. 14 , and the "second end 12312" refers to the lower end of the first arm 1231 as shown in FIG. 14 .

[0118] Similarly, a first end 12321 of the second arm 1232 is pivotally connected to the mounting bracket 121 via a third connecting pin 1237, and a second end 12322 of the second arm 1232 is pivotally connected to the pedal bracket 122 via a fourth connecting pin 1238. At least one of the first arm 1231 and the second arm 1232 can be connected to the motor 13. Therefore, the motor 13 drives at least one of the first arm 1231 and the second arm 1232 to pivot, thereby driving at least one of the first arm 1231 and the second arm 1232 to extend and retract the telescopic pedal 11 via the pedal bracket 122.

[0119] As shown in FIG15 , the telescopic mechanism 12 is a five-link mechanism 12b, comprising a mounting bracket 121, a pedal bracket 122, and an arm assembly connected between the mounting bracket 121 and the pedal bracket 122. The mounting bracket 121 is mounted on the vehicle body 21 or the fixed pedal, and the telescopic pedal 11 is mounted on the pedal bracket 122.

[0120] The arm assembly includes a first arm 1231, a second arm 1232, and a third arm 1233. The first arm 1231 has a first end 12311 and a second end 12312. "First end 12311" herein refers to the upper end of the first arm 1231 as shown in FIG15 , and "second end 12312" refers to the lower end of the first arm 1231 as shown in FIG15 . The first end 12311 of the first arm 1231 is pivotally connected to the mounting support 121 via a first connecting pin 1235 , and the second end 12312 of the first arm 1231 is pivotally connected to the pedal support 122 via a second connecting pin 1236 .

[0121] The second arm 1232 has a first end 12321 and a second end 12322. The first end 12321 of the second arm 1232 is pivotally connected to the mounting bracket 121 via a third connecting pin 1237. The third arm 1233 has a first end 12331 and a second end 12332. The second end 12322 of the second arm 1232 and the first end 12331 of the third arm 1233 are pivotally connected via a fifth connecting pin 1239. The second end 12332 of the third arm 1233 is pivotally connected to the pedal bracket 122 via a fourth connecting pin 1238.

[0122] At least one of the first arm 1231 and the second arm 1232 can be connected to the motor 13. Thus, the motor 13 drives at least one of the first arm 1231 and the second arm 1232 to pivot, and at least one of the first arm 1231 and the second arm 1232 drives the telescopic pedal 11 to extend and retract via the pedal support 122. By employing the telescopic mechanism 12 in the form of a five-link mechanism, the stability and accuracy of the telescopic mechanism 12 during the telescopic process can be further improved.

[0123] As shown in Figure 16, the telescopic mechanism 12 is a six-link mechanism 12c and includes a mounting bracket 121, a pedal bracket 122, and an arm assembly. The arm assembly includes a first arm 1231, a second arm 1232, a third arm 1233, and a fourth arm 1234. The mounting bracket 121 is mounted on the vehicle body 21 or the fixed pedal, and the telescopic pedal 11 is mounted on the pedal bracket 122.

[0124] The first arm 1231 has a first end 12311 and a second end 12312. The "first end 12311" herein refers to the upper end of the first arm 1231 as shown in FIG16 , and the "second end 12312" refers to the lower end of the first arm 1231 as shown in FIG16 . The first end 12311 of the first arm 1231 is pivotally connected to the mounting support 121 via a first connecting pin 1235 , and the second end 12312 of the first arm 1231 is pivotally connected to the pedal support 122 via a second connecting pin 1236 .

[0125] Second arm 1232 has a first end 12321 and a second end 12322. First end 12321 of second arm 1232 is pivotally connected to mounting support 121 via third connecting pin 1237. Third arm 1233 has a first end 12331 and a second end 12332. Second end 12322 of second arm 1232, first end 12331 of third arm 1233, and first end 12341 of fourth arm 1234 are pivotally connected together via fifth connecting pin 1239. Second end 12332 of third arm 1233 is pivotally connected to pedal support 122 via fourth connecting pin 1238. Second end 12342 of fourth arm 1234 is connected to first arm 1231 via sixth connecting pin 1230.

[0126] As shown in FIG16 , the second end 12322 of the second arm 1232 has a U-shaped arm slot 12323, and the first end 12331 of the third arm 1233 has a protrusion 12333 adapted to the arm slot 12323. The protrusion 12333 fits in the arm slot 12323, and the fourth connecting pin 1238 passes through the protrusion 12333.

[0127] 16 , the boss 12333 includes two lugs 12334 spaced apart from each other, and the first end 12341 of the fourth arm 1234 fits between the two lugs 12334. In other words, an arm slot is provided between the two lugs 12334 spaced apart from each other, and the first end 12341 of the fourth arm 1234 is accommodated in the arm slot.

[0128] Optionally, the second end 12342 of the fourth arm 1234 is connected to the middle of the first arm 1231. This can make the telescopic device 12 more stable, evenly stressed, and less prone to deformation.

[0129] 16 , the first arm 1231 defines a first arm slot 12313, and the second end 12342 of the fourth arm 1234 fits into the first arm slot 12313. The second arm 1232 and the third arm 1233 are substantially coaxial, and the first arm 1231 is substantially parallel to the second arm 1232 and the third arm 1233.

[0130] The six-link mechanism 12c has a more compact structure, more uniform force distribution, smoother movement, greater structural rigidity and strength, and a longer service life.

[0131] As shown in Figures 19-23 , the telescopic mechanism 12 is mounted on the fixed pedal 31. The telescopic pedal 11 is mounted on the telescopic mechanism 12 so that the telescopic mechanism 12 drives the telescopic pedal 11 to move between an extended position and a retracted position. In other words, the telescopic pedal 11 is mounted on the fixed pedal 31 via the telescopic mechanism 12, and is indirectly fixed to the vehicle body 21 through the fixed pedal 31.

[0132] Optionally, each fixed pedal 31 corresponds to a telescopic pedal 11, and each telescopic pedal 11 is mounted on multiple telescopic mechanisms 12. In the extended position, at least a portion of the telescopic pedal 11 extends outward from below the corresponding fixed pedal 31, so that the telescopic pedal 11 and the corresponding fixed pedal 31 form a two-step step. In the retracted position, the telescopic pedal 11 retracts below the corresponding fixed pedal 31.

[0133] Specifically, the vehicle 1 includes at least two fixed steps 31 and at least two telescopic steps 11. Some of the fixed steps 31 are located on the left side of the vehicle body 21, while the remaining fixed steps 31 are located on the right side of the vehicle body 21. Some of the telescopic steps 11 are located on the left side of the vehicle body 21, and each of these telescopic steps 11 is mounted on a plurality of telescopic mechanisms 12, which are mounted on the fixed steps 31. The remaining telescopic steps 11 are located on the right side of the vehicle body 21, and each of these telescopic steps 11 is mounted on a plurality of telescopic mechanisms 12, which are mounted on the remaining fixed steps 31.

[0134] Optionally, the rear portion of the vehicle body 21 is further provided with a fixed pedal 31 and at least one telescopic pedal 11. Each of the at least one telescopic pedal 11 is mounted on a plurality of telescopic mechanisms 12, and the plurality of telescopic mechanisms 12 are mounted on the fixed pedal 31 provided at the rear portion of the vehicle body 21.

[0135] As shown in Figures 4 and 19 , a fixed pedal 31 corresponds to multiple telescopic pedals 11, each of which is mounted on a telescopic mechanism 12. Specifically, multiple telescopic mechanisms 12 are mounted on a fixed pedal 31, with each telescopic mechanism 12 mounted on a telescopic pedal 11, so that multiple telescopic pedals 11 are mounted to a fixed pedal 31 via multiple telescopic mechanisms 12. In the extended position, at least a portion of the telescopic pedal 11 extends outward from below the fixed pedal 31, forming a two-step step with the telescopic pedal 11 and the fixed pedal 31. In the retracted position, the telescopic pedal 11 is retracted below the fixed pedal 31.

[0136] Specifically, the vehicle 1 includes two fixed pedals 31 and multiple telescopic pedals 11. One fixed pedal 31 is located on the left side of the vehicle body 21, and the other fixed pedal 31 is located on the right side of the vehicle body 21. The at least two telescopic pedals 11 are mounted in a one-to-one correspondence to at least two telescopic mechanisms 12, which are mounted to the one fixed pedal 31. The at least two telescopic pedals 11 are mounted in a one-to-one correspondence to at least two telescopic mechanisms 12, which are mounted to the other fixed pedal 31.

[0137] The multiple telescopic steps 11 associated with a single fixed step 31 can independently move between the extended and retracted positions. In other words, the multiple telescopic steps 11 attached to the same fixed step 31 can independently move between the extended and retracted positions. This allows the footrest device 10 to be more rationally structured by extending and retracting only the telescopic steps 11 corresponding to the vehicle door through which a user enters or exits the vehicle.

[0138] Specifically, two telescopic steps 11 are provided on the fixed step 31 on the left side of the vehicle body 21. One telescopic step 11 is opposite (corresponding to) the left front door 221, and the other telescopic step 11 is opposite (corresponding to) the left rear door 222. When a user enters or exits the vehicle through the left front door 221, the first telescopic step 11 extends and retracts, while the other telescopic step 11 remains stationary. When a user enters or exits the vehicle through the left rear door 222, the other telescopic step 11 extends and retracts, while the first telescopic step 11 remains stationary.

[0139] Two telescopic steps 11 are provided on a fixed step 31 on the right side of the vehicle body 21. One telescopic step 11 is opposite (corresponding to) the right front door, and the other telescopic step 11 is opposite (corresponding to) the right rear door. When a user enters or exits the vehicle through the right front door, the one telescopic step 11 extends and retracts, while the other telescopic step 11 remains stationary. When a user enters or exits the vehicle through the right rear door, the other telescopic step 11 extends and retracts, while the one telescopic step 11 remains stationary.

[0140] Optionally, a fixed pedal 31 and a plurality of telescopic pedals 11 are further provided at the rear of the vehicle body 21. The plurality of telescopic pedals 11 are mounted one-to-one to a plurality of telescopic mechanisms 12, which are mounted to the fixed pedal 31 at the rear of the vehicle body 21.

[0141] As shown in Figures 21 and 23, the vehicle body 21 includes a mounting frame, which includes a second horizontal plate 211 and a second vertical plate 212. The mounting frame 51 includes a third horizontal plate 517 and a third vertical plate 518. The third horizontal plate 517 is connected to the second horizontal plate 211, and the second vertical plate 212 is connected to the third vertical plate 518. This allows the mounting frame 51 to be more securely mounted on the vehicle body 21.

[0142] As shown in Figure 22, the fixed pedal 31 includes a frame 313 and a support plate 314. The frame 313 includes an inner tube 3131, an outer tube 3132, and a plurality of reinforcing tubes 3134. The reinforcing tubes 3134 are connected between the inner tube 3131 and the outer tube 3132. The frame 313 is connected to the support plate 316. The length of the inner tube 3131 is aligned with the length of the vehicle body 21, and the length of the outer tube 3132 is aligned with the length of the vehicle body 21. The plurality of reinforcing tubes 3134 are spaced apart along the length of the inner tube 3131 (outer tube 3132). The inner end of each reinforcing tube 3134 is connected to the inner tube 3131, and the outer end of each reinforcing tube 3134 is connected to the outer tube 3132.

[0143] The mounting frame 51 further includes a fourth horizontal plate 519.
