[0030] In the present application, when the connecting rod mechanism 111 is in the extended state, the pedal device 110 is in the extended state. When the connecting rod mechanism 111 is in the retracted state, the pedal device 110 is in the retracted state. When the telescopic seat 1112 is in the retracted position and the tilt arm 1115 is in the first tilt limit position, the connecting rod mechanism 111 is in the retracted state. When the telescopic seat 1112 is in the extended position and the tilt arm 1115 is in the second tilt limit position, the connecting rod mechanism 111 is in the extended state.

[0031] The connecting rod mechanism provided by the present application includes: a mounting base for fixing to a vehicle; a telescopic base, wherein in a first direction, the telescopic base is located below the mounting base; a first swing arm, wherein one end of the first swing arm is hinged to the mounting base at a first hinge point, and the other end of the first swing arm is hinged to the telescopic base at a second hinge point; a second swing arm, wherein one end of the second swing arm is hinged to the mounting base at a third hinge point, and the other end of the second swing arm is hinged to the telescopic base at a fourth hinge point; wherein, in the second direction, at least one of the first swing arm and the second swing arm can drive the telescopic base to extend and retract relative to the mounting base. Return; a flip arm, the flip arm and the telescopic seat are hinged at a fifth hinge point, and in the second direction, the fourth hinge point is located between the second hinge point and the fifth hinge point; at least one connecting rod assembly, in the third direction, the connecting rod assembly is arranged on at least one side of the two sides of the telescopic seat, one end of the connecting rod assembly is hinged to the mounting seat, and the other end of the connecting rod assembly is hinged to the flip arm at a sixth hinge point, and in the second direction, the sixth hinge point is closer to the second hinge point than the fifth hinge point; wherein, the connecting rod assembly can drive the flip arm to flip around the fifth hinge point. In the technical solution of the present application, when the telescopic seat extends relative to the mounting seat, the tilt arm extends along with the telescopic seat, and the connecting rod assembly drives the tilt arm to tilt outward, so that the pedal body fixed to the tilt arm has a sufficient extension length; when the telescopic seat retracts relative to the mounting seat, the tilt arm retracts along with the telescopic seat, and the connecting rod assembly drives the tilt arm to tilt inward, so that the pedal body fixed to the tilt arm can fit the vehicle skirt; because the connecting rod assembly is provided on at least one of the two sides of the telescopic seat, when the telescopic seat is in the retracted state, the overall height of the connecting rod mechanism in the first direction can be designed to be smaller, thereby improving the vehicle's passability and off-road performance. In this way, the connecting rod mechanism, while meeting the telescopic and tilting functions, can increase the ground clearance of the vehicle chassis in the retracted state, thereby improving the vehicle's passability and off-road performance.

[0032] Please refer to Figure 1-Figure 2 , Figure 1is a schematic structural diagram of a vehicle when the pedal device provided in some embodiments of the present application is in an extended state, Figure 2 : is a structural schematic diagram of a vehicle when the pedal device provided in some embodiments of the present application is in a retracted state. The vehicle 100 provided in the present application may include but is not limited to the pedal device 110. Among them, when the pedal device 110 is in an extended state (at this time, there is a first gap distance between the pedal body 113 in the pedal device 110 and the side skirt of the vehicle 100 along the first direction, and there is a second gap distance between the pedal body 113 in the pedal device 110 and the side skirt of the vehicle 100 along the second direction to form a stepped structure, thereby reducing the ground clearance of the vehicle 100 and making it easier for users to get on and off the vehicle. When the pedal device 110 is in a retracted state, the pedal body 113 in the pedal device 110 fits the side skirt of the vehicle 100, so as not to affect the passability of the vehicle 100 while keeping the appearance of the vehicle 100 neat and smooth.

[0033] The first clearance distance is greater than or equal to 100 mm and less than or equal to 200 mm, providing a sufficient foothold for passengers when stepping on the pedal body 113 of the pedal assembly 110, thereby improving user comfort and satisfaction. Specifically, the first clearance distance L3 can be 100 mm, 120 mm, 125 mm, 130 mm, 150 mm, 160 mm, 175 mm, or 200 mm. In this example, the first clearance distance is approximately 126 mm. The second clearance distance is greater than or equal to 100 mm and less than or equal to 150 mm, effectively reducing the ground clearance of the vehicle 100 when the pedal assembly 110 is extended, thereby facilitating entry and exit for various users and improving the vehicle's user-friendliness for shorter users. Specifically, the second clearance distance L4 can be 100 mm, 105 mm, 110 mm, 120 mm, 125 mm, 130 mm, 140 mm, or 150 mm. In this example, the second gap distance is approximately 137 mm.

[0034] Please refer to Figure 1-Figure 4 , Figure 3 is a schematic structural diagram of a pedal device provided in some embodiments of the present application when in an extended state. Figure 4 1 is a schematic diagram of the structure of the pedal device provided in some embodiments of the present application when in a retracted state. The pedal device 110 provided in the present application may include but is not limited to a connecting rod mechanism 111, a driving device 112, and a pedal body 113. Specifically, the driving device 112 is used to drive the first swing arm 1113 and / or the second swing arm 1114 in the connecting rod mechanism 111. The pedal body 113 is fixed to the flip arm 1115 in the connecting rod mechanism 111. Specifically, under the drive of the driving device 112, the pedal body 113 can be extended and flipped relative to the mounting seat 1111 in the connecting rod mechanism 111.

[0035] Furthermore, the pedal device 110 includes a plurality of connecting rod mechanisms 111. These connecting rod mechanisms 111 are arranged along the length of the pedal body 113. The driving device 112 is drivingly connected to one of the connecting rod mechanisms 111. In this embodiment, the pedal device 100 includes two connecting rod mechanisms 111, which are arranged along the length of the pedal body 113. The pedal device 100 is mounted on both sides of the vehicle 100. In other embodiments, increasing the number of connecting rod mechanisms 111, for example to three or more, can effectively increase the load-bearing capacity of the pedal device 110 and improve the smoothness of its movement. In other embodiments, the pedal device 100 includes one connecting rod mechanism 111, which is arranged in the middle of the pedal body 113 along the length of the pedal body 113. The pedal device 100 is mounted at a location corresponding to a vehicle door, such as the tailgate, front left door, front right door, rear left door, or rear right door.

[0036] Furthermore, when the mounting base 1111 of the linkage mechanism 111 is fixed to the chassis of the vehicle 100, if the telescopic base 1112 of the linkage mechanism 111 is in the extended position, the angle between the footrest surface of the pedal body 113 and the horizontal plane is greater than or equal to 0° and less than or equal to 5°, thereby preventing the user from slipping when stepping on the footrest surface. Specifically, the angle between the footrest surface of the pedal body 113 and the horizontal plane can be 0°, 1°, 1.7°, 2°, 2.5°, 3°, 3.7°, 4°, 4.5°, or 5°, etc. In this embodiment, when the telescopic base 1112 is in the extended position, the angle between the footrest surface of the pedal body 113 and the horizontal plane is approximately 1.57°. When the telescopic seat 1112 in the connecting rod mechanism 111 is in the retracted position, the angle between the pedal surface of the pedal body 113 and the horizontal plane is greater than or equal to 20° and less than or equal to 75°. This allows for better fit with the vehicle skirt, improved concealment when retracted, overall aesthetics, and passability, while also being compatible with a wider range of vehicle models. Specifically, the angle between the pedal surface of the pedal body 113 and the horizontal plane can be 20°, 23°, 25°, 27.5°, 28°, 30°, 33°, 35°, 37.5°, 40°, 45°, 47°, 50°, 52°, 55°, 57°, 60°, 62°, 65°, 67°, 70°, 72°, 73°, 74°, or 75°, etc. In this embodiment, when the telescopic seat 1112 is in the retracted position, the angle between the pedal surface of the pedal body 113 and the horizontal plane is approximately 60°.

[0037] Alternatively, the drive device 112 may be an electric motor. In this embodiment, the drive device 112 is in transmission connection with the first swing arm 1113 to drive the first swing arm 1113, which in turn, with the assistance of the second swing arm 1114, drives the telescopic seat 1112 to extend or retract relative to the mounting seat 1111. In this embodiment, when the pedal assembly 110 is in the extended state, the pedal load borne by the pedal body 113 is less likely to be transmitted to the drive device 112, thereby protecting the drive device 112.

[0038] Please refer to Figures 1-12 , Figure 5 is a schematic structural diagram of the connecting rod mechanism provided in some embodiments of the present application when it is in an extended state. Figure 6 Yes Figure 5 A planar schematic diagram of the linkage mechanism at one viewing angle, Figure 7 yes Figure 5 A planar schematic diagram of the linkage mechanism from another perspective, Figure 8 is a schematic structural diagram of the connecting rod mechanism provided in other embodiments of the present application when it is in an extended state. Figure 9 yes Figure 8 A planar schematic diagram of the linkage mechanism at one viewing angle, Figure 10 yes Figure 8 A planar schematic diagram of the linkage mechanism from another perspective, Figure 11 is a schematic structural diagram of the connecting rod mechanism provided in some embodiments of the present application when it is in a retracted state. Figure 12 yes Figure 11A planar schematic diagram of the connecting rod mechanism at a certain viewing angle. The connecting rod mechanism 111 provided in the present application may include but is not limited to a mounting base 1111, a telescopic base 1112, a first swing arm 1113, a second swing arm 1114, a tilting arm 1115, and at least one connecting rod assembly 1116. The mounting base 1111 is used to be fixed to the vehicle 100. In the first direction, the telescopic base 1112 is located below the mounting base 1111. In this embodiment, the first swing arm 1113 and the second swing arm 1114 can be attached to the chassis of the vehicle 100 through the mounting base 1111, so that the pedal device 110 can be installed and used as a separately installable accessory. The mounting base 1111 can also be attached to the chassis of the vehicle 100 through sheet metal to better adapt to the installation on the chassis of the vehicle 100. In some other embodiments, the first swing arm 1113 and the second swing arm 1114 can be directly attached to the chassis of the vehicle 100. One end of the first swing arm 1113 is hinged to the mounting base 1111 at a first hinge point D1. The other end of the first swing arm 1113 is hinged to the telescopic base 1112 at a second hinge point D2. One end of the second swing arm 1114 is hinged to the mounting base 1111 at a third hinge point D3. The other end of the second swing arm 1114 is hinged to the telescopic base 1112 at a fourth hinge point D4. In the second direction, at least one of the first swing arm 1113 and the second swing arm 1114 can drive the telescopic base 1112 to extend and retract relative to the mounting base 1111. In this embodiment, the first swing arm 1113 drives the telescopic base 1112 to extend and retract relative to the mounting base 1111. The tilt arm 1115 is hinged to the telescopic base 1112 at a fifth hinge point D5. In the second direction, the fourth hinge point D4 is located between the fifth hinge point D5 and the second hinge point D2. In the third direction, a link assembly 1116 is disposed on at least one of the two sides of the telescopic seat 1112. This reduces the overall height H of the link mechanism 111 in the first direction when the link mechanism 111 is retracted, thereby increasing the ground clearance of the vehicle 100 and, in turn, improving the vehicle's drivability and off-road performance. At least one link assembly 1116 is in transmission connection with the second swing arm 1114, enabling the second swing arm 1114 to drive the link assembly 1116. One end of the link assembly 1116 is hinged to the mounting seat 1111, and the other end of the link assembly 1116 is hinged to the flip arm 1115 at a sixth hinge point D6. In the second direction, the sixth hinge point D6 is closer to the second hinge point D2 than the fifth hinge point D5, enabling the link assembly 1116 to drive the flip arm 1115 to flip about the fifth hinge point D5.

[0039] Driven by the connecting rod assembly 1116, the tilting arm 1115 can tilt about the fifth hinge point D5 to an angle greater than or equal to 45° and less than or equal to 70°, allowing the pedal device 110 to be compatible with as many vehicle models as possible. Furthermore, driven by the connecting rod assembly 1116, the tilting arm 1115 can tilt about the fifth hinge point D5 to an angle greater than or equal to 55° and less than or equal to 62°. Specifically, the tilting arm 1115 can tilt about the fifth hinge point D5 to an angle of 45°, 46°, 47°, 49°, 51°, 52°, 53°, 54°, 55°, 56°, 56.5°, 57°, 58°, 58.5°, 59°, 60°, 61°, 62°, 64°, 66°, 68°, or 70°, etc. In this embodiment, when the flip arm moves from the first flip limit position to the second flip limit position or from the second flip limit position to the first flip limit position, the flip angle of the flip arm around the fifth hinge point is approximately 58.5°.

[0040] In this embodiment, when the telescopic base 1112 is in the retracted position, the overall height H of the connecting rod mechanism 111 in the first direction can be greater than 0 mm and less than 70 mm. This ensures that when the pedal assembly mounted on the vehicle is retracted, the vehicle still has adequate ground clearance, thereby improving the vehicle's maneuverability and off-road performance. Furthermore, when the telescopic base 1112 is in the retracted position, the overall height H of the connecting rod mechanism 111 in the first direction can be greater than 63 mm and less than 69 mm. Specifically, the overall height H of the connecting rod mechanism 111 can be 55 mm, 56 mm, 57 mm, 58 mm, 60 mm, 62 mm, 64 mm, 65 mm, 66 mm, 67 mm, 68 mm, or 69 mm, etc. In this embodiment, the overall height H of the connecting rod mechanism 111 is approximately 66 mm.

[0041] In this embodiment, there are two connecting rod assemblies 1116. In the third direction, one connecting rod assembly is located on the right side of the telescopic seat 1112, and the other connecting rod assembly 1116 is located on the left side of the telescopic seat 1112. When the connecting rod assembly 1116 drives the flip arm 1115 to flip around the fifth hinge point D5, it can disperse the force at the support point and make the force at the support point more uniform. At the same time, the flipping movement is more coordinated, thereby improving the load-bearing capacity and life of the connecting rod mechanism 111, and avoiding abnormal noise caused by increased wear and affecting comfort.

[0042] In this embodiment, one end of the connecting rod assembly 1116 is hinged to the mounting base 1111 at the third hinge point D3, so that the hinge between the connecting rod assembly and the mounting base and the hinge between the second swing arm and the mounting base can use the same hinge axis, thereby simplifying the structural design, reducing the number of parts and reducing costs.

[0043] In this embodiment, at least one of the first swing arm 1113 and the second swing arm 1114 drives the telescopic seat 1112 to extend or retract relative to the mounting seat 1111, while the connecting rod assembly 1116 drives the flip arm 1115 to flip away from or toward the mounting seat 1111 around the fifth hinge point D5.

[0044] Specifically, along the second direction, the sixth hinge point D6 is closer to the second hinge point D2 than the fifth hinge point D5. Along the first direction, the sixth hinge point D6 is located above the fifth hinge point D5. This layout allows the tilt arm 1115 to be driven by the connecting rod assembly 1116 to tilt about the fifth hinge point D5 as the telescopic base 1112 extends and retracts. More specifically, when the telescopic base 1112 extends, the connecting rod assembly 1116 drives the tilt arm 1115 to tilt outward about the fifth hinge point D5. When the telescopic base 1112 retracts, the connecting rod assembly 1116 drives the tilt arm 1115 to tilt inward about the fifth hinge point D5.

[0045] Furthermore, the tilting arm 1115 can tilt about the fifth hinge point D5 to an angle greater than or equal to 20° and less than 59°, allowing the pedal body 113 to fit snugly on the vehicle skirt and adapting to a wider range of vehicle models. Specifically, the tilting arm 1115 can tilt about the fifth hinge point D5 to an angle of 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 56°, 57°, 58°, or 58.4°, etc. In this embodiment, the tilting arm 1115 can tilt about the fifth hinge point D5 to an angle of approximately 58.4°.

[0046] Furthermore, the distance between the first hinge point D1 and the second hinge point D2 is the first center distance. The distance between the third hinge point D3 and the fourth hinge point D4 is the second center distance. The distance between the first hinge point D1 and the third hinge point D3 is the third center distance. The distance between the second hinge point D2 and the fourth hinge point D4 is the fourth center distance. The first center distance is smaller than the second center distance, and the fourth center distance is smaller than the third center distance. This allows the first swing arm 1113 to move the telescopic seat 1112 to a retracted position, thereby occupying less floor space in the vehicle 100. The difference between the second center distance and the first center distance is greater than or equal to 9 mm and less than or equal to 15 mm. The difference between the third center distance and the fourth center distance is greater than or equal to 3 mm and less than or equal to 9 mm. This ensures that the telescopic seat 1112 has a certain swing amplitude and a relatively smooth arc trajectory, allowing it to smoothly extend from the chassis while preventing it from colliding with protruding objects on the ground due to excessive swing amplitude. Specifically, the difference between the second center distance and the first center distance can be 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm, etc. The difference between the third center distance and the fourth center distance can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or 9 mm, etc. In this embodiment, the difference between the second center distance and the first center distance is approximately 12 mm. The difference between the third center distance and the fourth center distance is approximately 6 mm.

[0047] Furthermore, the connecting rod assembly 1116 may include, but is not limited to, a first connecting rod 1116a and a second connecting rod 1116b. One end of the first connecting rod 1116a and one end of the second connecting rod 1116b are hingedly connected at a seventh hinge point D7. The other end of the first connecting rod 1116a is hingedly connected to the mounting base 1111 at an eighth hinge point D8. The other end of the second connecting rod 1116b is hingedly connected to the flip arm 1115 at a sixth hinge point D6.

[0048] In this embodiment, at least one connecting rod assembly 1116 is in transmission connection with the second swing arm 1114. Specifically, the second swing arm 1114 is provided with a connecting shaft 1114a. The second swing arm 1114 is fixedly connected to the structure between the ends of the first connecting rod 1116a via the connecting shaft 1114a to drive the connecting rod assembly 1116.

[0049] When the telescopic seat 1112 is in the retracted position and the tilt arm is in the first tilt limit position, the line connecting the eighth hinge point D8 and the seventh hinge point D7 forms a first angle α with the line connecting the sixth hinge point D6 and the seventh hinge point D7. This first angle α is greater than or equal to 0° and less than 45°. By locating the eighth hinge point D8, the seventh hinge point D7, and the sixth hinge point D6 on the same straight line or approximately on the same straight line, the inertial load acting on the tilt arm 1115 during driving of the vehicle 100 can be prevented from automatically extending the telescopic seat 1112 or being transmitted to the drive device 112. This approach enhances the stability of the pedal device 110 in the retracted state. Furthermore, the first angle α can be greater than or equal to 21° and less than 27°.

[0050] Specifically, the first angle α can be 0°, 1°, 2°, 3°, 5°, 7.5°, 10°, 12.5°, 15°, 20°, 21°, 23°, 23.5°, 24°, 24.5°, 25°, 27°, 27.5°, 30°, 32°, 35°, 37.5°, 40°, 41°, 42°, 43°, or 44°, etc. In this embodiment, the first angle α is approximately 24°.

[0051] When the telescopic seat 1112 is in the extended position and the tilt arm 1115 is in the second extreme tilt position, the line connecting the eighth hinge point D8 and the seventh hinge point D7 and the line connecting the sixth hinge point D6 and the seventh hinge point D7 form a second angle β. This second angle β is greater than 90° and less than 180°. By forming a larger second angle β, when the pedal assembly 110 is in the extended position, the pedaling load acting on the tilt arm 1115 can generate an outward force component in the second direction acting on the telescopic seat 1112, thereby maintaining the telescopic seat 1112 in the extended position. Furthermore, the second angle β can be greater than 92° and less than 98°.

[0052] Specifically, the second angle β may be 91°, 91.5°, 92°, 93.5°, 95°, 100°, 105°, 110°, 120°, 130°, 140°, 150°, 155°, 160°, 165°, 170°, 171.5°, 173°, 174.5°, 176°, 177.5°, or 179°, etc. In this embodiment, the second angle β is approximately 95°.

[0053] In this embodiment, the flip arm 1115 is generally L-shaped. The flip arm 1115 may include, but is not limited to, a connecting portion and a supporting portion. The end of the connecting portion, distal from the supporting portion, is hingedly connected to the connecting rod assembly 1116 at a seventh hinge point D7. The end of the connecting portion, proximal to the supporting portion, is hingedly connected to the telescopic base 1112 at a fifth hinge point D5.

[0054] The connecting rod mechanism 111 provided in the present application includes: a mounting seat 1111, which is used to be fixed to the vehicle 100; a telescopic seat 1112, in the first direction, the telescopic seat 1112 is located below the mounting seat 1111; a first swing arm 1113, one end of the first swing arm 1113 is hinged to the mounting seat 1111 at a first hinge point D1, and the other end of the first swing arm 1113 is hinged to the telescopic seat 1112 at a second hinge point D2; a second swing arm 1114, one end of the second swing arm 1114 is hinged to the mounting seat 1111 at a third hinge point D3, and the other end of the second swing arm 1114 is hinged to the telescopic seat 1112 at a fourth hinge point D4; wherein, in the second direction, at least one of the first swing arm 1113 and the second swing arm 1114 can drive the telescopic seat 1111 to rotate. 12 extends and retracts relative to the mounting base 1111; the flip arm 1115, the flip arm 1115 and the telescopic base 1112 are hinged at the fifth hinge point D5, and in the second direction, the fourth hinge point D4 is located between the second hinge point D2 and the fifth hinge point D5; at least one connecting rod assembly 1116, in the third direction, the connecting rod assembly 1116 is arranged on at least one side of the two sides of the telescopic base 1112, one end of the connecting rod assembly 1116 is hinged to the mounting base 1111, and the other end of the connecting rod assembly 1116 is hinged to the flip arm 1115 at the sixth hinge point D6, and in the second direction, the sixth hinge point D6 is closer to the second hinge point D2 than the fifth hinge point D5; wherein, the connecting rod assembly 1116 can drive the flip arm 1115 to flip around the fifth hinge point D5. In the technical solution of the present application, when the telescopic seat 1112 is extended relative to the mounting seat 1111, the flip arm 1115 is extended along with the telescopic seat 1112, and the connecting rod assembly 1116 drives the flip arm 1115 to flip outward, so that the pedal body 113 fixed to the flip arm 1115 has a sufficient extension length; when the telescopic seat 1112 is retracted relative to the mounting seat 1111, the flip arm 1115 is retracted along with the telescopic seat 1112, and the connecting rod assembly 1116 drives the flip arm 1115 to flip inward, so that the pedal body 113 fixed to the flip arm 1115 can fit the vehicle skirt; because the connecting rod assembly 1116 is arranged on at least one of the two sides of the telescopic seat 1112, when the telescopic seat 1112 is in the retracted state, in the first direction, the overall height H of the connecting rod mechanism 111 can be designed to be smaller, so as to improve the passability and off-road performance of the vehicle 100. In this way, the link mechanism 111 can increase the ground clearance of the chassis of the vehicle 100 in the retracted state on the basis of satisfying the telescopic and flipping functions, thereby improving the passability and off-road performance of the vehicle 100.
