[0044] Please refer to Figure 1-Figure 2 , Figure 1 is a schematic structural diagram of a vehicle when a pedal device provided in some embodiments of the present application is in an extended state, Figure 2 1 is a schematic diagram of the structure 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. When the pedal device 110 is in an extended state (at this time, the telescopic seat 1112 in the pedal device 110 is in an extended state), there is a first gap distance L3 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 L4 between the pedal body 113 in the pedal device 110 and the side skirt of the vehicle 100 along the second direction, so as to form a step structure, reduce the ground clearance of the vehicle 100, and facilitate users to get on and off the vehicle. When the pedal device 110 is in a retracted state (at this time, the telescopic seat 1112 in 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 to keep the appearance of the vehicle 100 neat and smooth without affecting the passability of the vehicle 100.

[0045] Among them, the size of the first gap distance L3 is greater than or equal to 100mm and less than or equal to 200mm, so that the driver and passenger have enough footholds when stepping on the pedal body 113 in the pedal device 110, thereby improving the comfort and satisfaction of the user. Specifically, the size of the first gap distance L3 can be 100mm, 120mm, 125mm, 130mm, 150mm, 160mm, 175mm or 200mm, etc. In this example, the size of the first gap distance L3 is 126.28mm. The size of the second gap distance L4 is greater than or equal to 100mm and less than or equal to 150mm, so that when the pedal device 110 is in the extended state, the ground clearance of the vehicle 100 can be effectively reduced, thereby facilitating different users to enter and exit the cabin, and improving the friendliness to users with short stature. Specifically, the size of the second gap distance L4 can be 100mm, 105mm, 110mm, 120mm, 125mm, 130mm, 140mm or 150mm, etc. In this example, the second gap distance L4 is 137 mm.

[0046] Please refer to Figure 1-Figure 4 , Figure 3 is a schematic diagram of the structure of the pedal device provided in some embodiments of the present application when it is 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 it is in a retracted state. The pedal device 110 provided in the present application may include but is not limited to a connecting rod assembly 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 assembly 111. The pedal body 113 is fixed to the support arm 1115 in the connecting rod assembly 111. Among them, 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 assembly 111.

[0047] Further, the pedal device 110 includes a plurality of connecting rod assemblies 111. The plurality of connecting rod assemblies 111 are arranged along the length direction of the pedal body 113. In this embodiment, the pedal device 100 includes two connecting rod assemblies 111, the two connecting rod assemblies 111 are arranged along the length direction of the pedal body 113, and the pedal device 100 is installed on both sides of the vehicle 100. In this embodiment, increasing the number of connecting rod assemblies 111, such as three or more, can effectively improve the load-bearing capacity of the pedal device 110 and improve the stability of the movement of the pedal device 110. In some other embodiments, the pedal device 100 includes a connecting rod assembly 111, and along the length direction of the pedal body 113, one connecting rod assembly 111 is arranged at the middle position of the pedal body 113, and the pedal device 100 is installed at the position corresponding to the door, such as the tailgate, the front left door, the front right door, the rear left door and the rear right door.

[0048] Furthermore, when the mounting seat 1111 in the connecting rod assembly 111 is fixed to the chassis of the vehicle 100, if the telescopic seat 1112 in the connecting rod assembly 111 is in the extended state, the angle between the pedal surface M of the pedal body 113 and the horizontal plane is greater than or equal to 0° and less than or equal to 5°, so as to prevent the user from slipping outward easily when stepping on the pedal surface M. Specifically, the angle between the pedal surface M of the pedal body 113 and the horizontal plane can be 0°, 1°, 1.7°, 2°, 2.5°, 3°, 3.7°, 4°, 4.5°, 5°, etc. In this embodiment, when the telescopic seat 1112 is in the extended state, the angle between the pedal surface M of the pedal body 113 and the horizontal plane is 1.14°. If the telescopic seat 1112 in the connecting rod assembly 111 is in the retracted state, the angle between the pedal surface M of the pedal body 113 and the horizontal plane is greater than or equal to 20° and less than or equal to 40°, so as to better fit the vehicle skirt, thereby improving the retracted concealment, overall aesthetics and passability. Specifically, the angle between the pedal surface M of the pedal body 113 and the horizontal plane can be 20°, 23°, 25°, 27.5°, 28°, 30°, 33°, 35°, 37.5° and 40°, etc. In this embodiment, when the telescopic seat 1112 is in the retracted state, the angle between the pedal surface M of the pedal body 113 and the horizontal plane is 27.39°.

[0049] Optionally, the driving device 112 may be an electric motor. In this embodiment, the driving device 112 is connected to the first swing arm 1113 in a transmission manner to drive the first swing arm 1113, and then, with the assistance of the second swing arm 1114, the telescopic seat 1112 is driven to extend or retract relative to the mounting seat 1111. In this embodiment, when the pedal device 110 is in an extended state (at this time, the telescopic seat 1112 is in an extended state), the pedal load borne by the pedal body 113 is difficult to be transmitted to the driving device 112, thereby protecting the driving device 112.

[0050] Please refer to Figure 1-Figure 9 , Figure 5 is an exploded schematic diagram of a connecting rod assembly provided in some embodiments of the present application, Figure 6 is a schematic diagram of the structure of the connecting rod assembly provided in some embodiments of the present application when it is in a retracted state, Figure 7 is a cross-sectional view of a connecting rod assembly provided in some embodiments of the present application when it is in a retracted state, Figure 8 is a schematic diagram of the structure of the connecting rod assembly provided in some embodiments of the present application when it is in an extended state, Fig. 9A cross-sectional view of a connecting rod assembly provided in some embodiments of the present application when in an extended state. The connecting rod assembly 111 provided in the present application may include but is not limited to a mounting seat 1111, a telescopic seat 1112, a first swing arm 1113, a second swing arm 1114, a support arm 1115 and a linkage arm 1116. Specifically, along the first direction, the telescopic seat 1112 is located below the mounting seat 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 seat 1111, so that the pedal device 110 can be installed and used as a separate accessory. 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 seat 1111 at a first hinge point D1. The other end of the first swing arm 1113 is hinged to the telescopic seat 1112 at a second hinge point D2. One end of the second swing arm 1114 is hinged to the mounting seat 1111 at a third hinge point D3. The other end of the second swing arm 1114 is hinged to the telescopic seat 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 seat 1112 to extend and retract relative to the mounting seat 1111. The second direction is perpendicular to the first direction. In this embodiment, the first swing arm 1113 drives the telescopic seat 1112 to extend and retract relative to the mounting seat 1111. The support arm 1115 is hinged to the telescopic seat 1112 at a fifth hinge point D5. The fourth hinge point D4 is located between the fifth hinge point D5 and the second hinge point D2. One end of the linkage arm 1116 is hinged to the other end of the second swing arm 1114 at a sixth hinge point D6. The other end of the linkage arm 1116 is hinged to the support arm 1115 at a seventh hinge point D7. Among them, the linkage arm 1116 can drive the support arm 1115 to flip around the fifth hinge point D5.

[0051] Specifically, along the second direction, the sixth hinge point D6 is farther from the second hinge point D2 relative to the fourth hinge point D4, and the seventh hinge point D7 is closer to the second hinge point D2 relative to the fifth hinge point D5. Along the first direction, the seventh hinge point D7 is located above the fifth hinge point D5. Through such a layout, the support arm 1115 can be driven by the linkage arm 1116 to flip around the fifth hinge point D5 during the process of following the telescopic seat 1112 to extend and retract. More specifically, during the process of extending the telescopic seat 1112, the linkage arm 1116 drives the support arm 1115 to flip outward around the fifth hinge point D5; during the process of retracting the telescopic seat 1112, the linkage arm 1116 drives the support arm 1115 to flip inward around the fifth hinge point D5.

[0052] Furthermore, the angle at which the support arm 1115 can flip around the fifth hinge point D5 is greater than or equal to 20° and less than or equal to 35°, so that the pedal body 113 fits the skirt of the vehicle. Specifically, the angle at which the support arm 1115 can flip around the fifth hinge point D5 can be 20°, 25°, 30°, 35°, etc. In this embodiment, the angle at which the support arm 1115 can flip around the fifth hinge point D5 is 26.3°.

[0053] Further, the distance between the first hinge point D1 and the second hinge point D2 is the first center distance L1. The distance between the third hinge point D3 and the fourth hinge point D4 is the second center distance L2. The first center distance L1 is smaller than the second center distance L2, so that when the first swing arm 1113 drives the telescopic seat 1112 to be in the retracted state, it occupies a smaller chassis space of the vehicle 100.

[0054] When the telescopic seat 1112 is in the extended state or the retracted state, the line between the second hinge point D2 and the fourth hinge point D4 can form an angle of 0° to 3° with the horizontal plane. And the difference between the second center distance L2 and the first center distance L1 is greater than or equal to 6 mm and less than or equal to 12 mm. In this way, the telescopic seat 1112 has a certain swing amplitude and the arc trajectory of the swing is relatively smooth, so that the telescopic seat 1112 can be smoothly extended from the chassis without colliding with protrusions on the ground due to excessive swing amplitude.

[0055] Specifically, when the pedal device 110 is installed on the chassis of the vehicle 100 and the telescopic seat 1112 is in an extended state or a retracted state, the angle formed by the line between the second hinge point D2 and the fourth hinge point D4 and the horizontal plane can be 0°, 0.2°, 0.3°, 0.45°, 0.66°, 1.24°, 1.51°, 2°, 2.4°, 2.62° and 3°, etc.

[0056] Specifically, the difference between the second center distance L2 and the first center distance L1 may be 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc. In this embodiment, the difference between the second center distance L2 and the first center distance L1 is 9 mm.

[0057] Further, when the telescopic seat 1112 is in the retracted state, the line between the sixth hinge point D6 and the seventh hinge point D7 and the line between the sixth hinge point D6 and the third hinge point D3 form a first angle α. The first angle α is an acute angle. The magnitude of the first angle α is greater than or equal to 0° and less than or equal to 10°. By making the sixth hinge point D6, the seventh hinge point D7 and the third hinge point D3 located on the same straight line or approximately located on the same straight line, it is possible to avoid the inertial load acting on the support arm 1115 during the driving process of the vehicle 100, so that the telescopic seat 1112 is automatically extended or transmitted to the driving device 112. In this way, the stability of the pedal device 110 in the retracted state can be increased. For example, when the pedal device 110 is subjected to external interference forces such as vibration or slight collision, the first angle α can form a relatively stable force transmission relationship between the sixth hinge point D6, the seventh hinge point D7 and the third hinge point D3, so that the pedal device 110 can better resist these external interferences and maintain a stable state.

[0058] Specifically, the first angle α may be 0°, 1.3°, 2.5°, 3.7°, 4.2°, 5°, 6.3°, 7.5°, 8.7°, 9.2°, 10°, etc. In this embodiment, the first angle α is 4.19°.

[0059] Further, when the telescopic seat 1112 is in the retracted state, the fourth hinge point D4, the seventh hinge point D7, the sixth hinge point D6 and the fifth hinge point D5 constitute the four corner points of the first quadrilateral Q1. In the first quadrilateral Q1, the fourth hinge point D4 and the seventh hinge point D7 are located above the sixth hinge point D6 and the fifth hinge point D5 along the first direction, and the fourth hinge point D4 is obliquely opposite to the fifth hinge point D5. In the second direction, the fourth hinge point D4 is closer to the second hinge point D2 than the seventh hinge point D7. In this way, the connecting rod assembly 111 can be made more compact and reliable when in the retracted state, thereby reducing the occupied space and ensuring the retraction concealment of the pedal device 110.

[0060] Further, when the telescopic seat 1112 is in the retracted state, the line between the fourth hinge point D4 and the seventh hinge point D7 and the line between the sixth hinge point D6 and the fifth hinge point D5 form a second angle β. The magnitude of the second angle β is greater than or equal to 0° and less than or equal to 10°. And / or, when the telescopic seat 1112 is in the retracted state, the line between the fourth hinge point D4 and the sixth hinge point D6 and the line between the seventh hinge point D7 and the fifth hinge point D5 form a third angle γ, and the magnitude of the third angle γ is greater than or equal to 0° and less than or equal to 5°. In this way, the retraction of the connecting rod assembly 111 is compact and reliable, and it is also conducive to smoothly driving the support arm 1115 to flip outward through the linkage arm 1116 when it needs to be extended.

[0061] Specifically, the second angle β may be 0°, 0.7°, 1.3°, 2.5°, 3.8°, 4.2°, 5°, 5.7°, 6.3°, 7.5°, 8.8°, 9.2°, 10°, etc. The third angle γ may be 0°, 0.3°, 0.7°, 1.2°, 2.5°, 3.1°, 3.7°, 4.3°, 4.6°, 5°, etc. In the present embodiment, the second angle β is 5.58°, and the third angle γ is 0.75°.

[0062] Further, when the telescopic seat 1112 is in the extended state, the line between the fifth hinge point D5 and the fourth hinge point D4 and the line between the fifth hinge point D5 and the third hinge point D3 form a sixth angle g. The sixth angle g is an acute angle. The magnitude of the sixth angle g is greater than or equal to 0° and less than or equal to 10°. By making the fifth hinge point D5, the fourth hinge point D4 and the third hinge point D3 located on the same straight line or approximately located on the same straight line, it is possible to avoid the pedal load acting on the support arm 1115 causing the telescopic seat 1112 to automatically retract or be transmitted to the drive device 112 when the pedal device 110 is in the extended state.

[0063] Specifically, the sixth angle g may be 0°, 1.3°, 2.5°, 3.7°, 4.2°, 5°, 6.3°, 7.5°, 8.7°, 9.2°, 10°, etc. In this embodiment, the sixth angle g is 9.57°.

[0064] Furthermore, when the telescopic seat 1112 is in the extended state, the sixth hinge point D6, the seventh hinge point D7, the fourth hinge point D4 and the fifth hinge point D5 constitute the four corner points of the second quadrilateral Q2. In the second quadrilateral Q2, the sixth hinge point D6 and the seventh hinge point D7 are located above the fourth hinge point D4 and the fifth hinge point D5 along the first direction, and the sixth hinge point D6 is obliquely opposite to the fifth hinge point D5. In the second direction, the sixth hinge point D6 is closer to the second hinge point D2 than the seventh hinge point D7. In this way, the connecting rod assembly 111 can be extended to the full extent when in the extended state, thereby increasing the extended length and ensuring that the driver and passengers have enough footholds.

[0065] Further, when the telescopic seat 1112 is in the extended state, the line between the sixth hinge point D6 and the seventh hinge point D7 and the line between the fourth hinge point D4 and the fifth hinge point D5 form a fourth angle θ. The magnitude of the fourth angle θ is greater than or equal to 0° and less than or equal to 5°. And / or, when the telescopic seat 1112 is in the extended state, the line between the sixth hinge point D6 and the fourth hinge point D4 and the line between the seventh hinge point D7 and the fifth hinge point D5 form a fifth angle δ. The magnitude of the fifth angle δ is greater than or equal to 45° and less than or equal to 55°. In this way, the connecting rod assembly 111 is extended into place, and when it needs to be retracted, it is possible to smoothly drive the support arm 1115 to flip inward through the linkage arm 1116.

[0066] Specifically, the fourth angle θ may be 0°, 0.3°, 0.7°, 1.2°, 2.5°, 3.1°, 3.7°, 4.3°, 4.6°, 5°, etc. The fifth angle δ may be 45°, 45.3°, 45.7°, 46.2°, 47.5°, 48.1°, 48.7°, 49.3°, 49.6°, 55°, etc. In the present embodiment, the fourth angle θ is 0.27°, and the fifth angle δ is 49.92°.

[0067] In this embodiment, the second swing arm 1114 is in a Z-shape as a whole. The second swing arm 1114 may include but is not limited to a first connecting portion 1114a, a main body portion 1114b and a second connecting portion 1114c. Specifically, the main body portion 1114b is connected between the first connecting portion 1114a and the second connecting portion 1114c. One end of the first connecting portion 1114a away from the main body portion 1114b is hinged to the mounting seat 1111 at a third hinge point D3. One end of the main body portion 1114b away from the first connecting portion 1114a is hinged to the telescopic seat 1112 at a fourth hinge point D4. One end of the second connecting portion 1114c away from the main body portion 1114b is hinged to the linkage arm 1116 at a sixth hinge point D6.

[0068] Furthermore, the second swing arm 1114 is provided with a receiving groove 1114d. When the telescopic seat 1112 is in the retracted state, the linkage arm 1116 is received in the receiving groove 1114d. In this way, the space can be effectively utilized, and the volume of the pedal device 110 can be reduced when the telescopic seat 1112 is in the retracted state, thereby ensuring the retraction concealment of the pedal device 110.

[0069] In this embodiment, the support arm 1115 is L-shaped as a whole. The support arm 1115 may include but is not limited to a third connecting portion 1115a and a supporting portion 1115b connected to each other. One end of the third connecting portion 1115a away from the supporting portion 1115b is hinged to the linkage arm 1116 at the seventh hinge point D7, and one end of the third connecting portion 1115a close to the supporting portion 1115b is hinged to the telescopic seat 1112 at the fifth hinge point D5.

[0070] In this embodiment, the telescopic seat 1112 may include but is not limited to a first molded bottom plate 1112a, a second molded bottom plate 1112b and a side plate 1112c. The first molded bottom plate 1112a and the second molded bottom plate 1112b are spaced and connected between the two side plates 1112c. One end of the side plate 1112c is hinged to the first swing arm 1113 at the second hinge point D2. The other end of the side plate 1112c is hinged to the support arm 1115 at five hinge points. The structure between the two ends of the side plate 1112c is hinged to the second swing arm 1114 at the fourth hinge point D4. The space enclosed by the side plate 1112c, the first molded bottom plate 1112a and the second molded bottom plate 1112b can accommodate a partial structure of the first swing arm 1113, a partial structure of the support arm 1115 and a partial structure of the second swing arm 1114. In this way, the relative position relationship between the components is made closer, thereby reducing the volume of the pedal device 110 in the retracted state and improving the space utilization. At the same time, it can also effectively reduce the impact of foreign objects such as dust, accumulated water, and flying stones on the first swing arm 1113, the second swing arm 1114, the support arm 1115, and the linkage arm 1116 during the driving of the vehicle 100, thereby improving the service life of the pedal device 110.

In the technical solution of the present application, when the telescopic seat 1112 is extended relative to the mounting seat 1111, the support arm 1115 is turned outwards as the telescopic seat 1112 is extended, so that the pedal body 113 fixed to the support arm 1115 has a sufficient extension length; when the telescopic seat 1112 is retracted relative to the mounting seat 1111, the support arm 1115 is turned inwards as the telescopic seat 1112 is retracted, so that the pedal body 113 fixed to the support arm 1115 can fit the vehicle skirt. In this way, the connecting rod assembly 111 can make the pedal device 110 installed on the new energy vehicle have a sufficient extension length and ensure the retraction concealment.
