Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] In this application, the first direction refers to the direction of the Z-axis, the second direction refers to the direction of the Y-axis, the upper direction refers to the direction indicated by the positive direction of the Z-axis, the lower direction refers to the direction indicated by the negative direction of the Z-axis, the outward direction refers to the direction indicated by the positive direction of the Y-axis, and the inward direction refers to the direction indicated by the negative direction of the Y-axis.

[0042] The linkage assembly provided in this application includes a mounting base; a telescopic base, which is located below the mounting base along a first direction; a first swing arm, one end of which is hinged to the mounting base at a first hinge point, and the other end of which is hinged to the telescopic base at a second hinge point; a second swing arm, one end of which is hinged to the mounting base at a third hinge point, and the other end of which is hinged to the telescopic base at a fourth hinge point; wherein, along a second direction, at least one of the first and second swing arms is capable of causing the telescopic base to extend and retract relative to the mounting base; a support arm, which is hinged to the telescopic base at a fifth hinge point, and the fourth hinge point is located between the fifth and second hinge points; and a linkage arm, one end of which is hinged to the other end of the second swing arm at a sixth hinge point, and the other end of which is hinged to the support arm at a seventh hinge point; wherein, the linkage arm is capable of causing the support arm to rotate around the fifth hinge point. In the technical solution of this application, during the extension of the telescopic seat relative to the mounting seat, the support arm flips outward as the telescopic seat extends, ensuring that the pedal body fixed to the support arm has sufficient extension length. During the retraction of the telescopic seat relative to the mounting seat, the support arm flips inward as the telescopic seat retracts, ensuring that the pedal body fixed to the support arm fits snugly against the vehicle skirt. In this way, the linkage assembly enables the pedal device installed on new energy vehicles to have both sufficient extension length and concealed retraction.

[0043] Please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of a vehicle with the pedal device in the extended state according to some embodiments of this application, and Figure 2 is a structural schematic diagram of a vehicle with the pedal device in the retracted state according to some embodiments of this application. The vehicle 100 provided in this application may include, but is not limited to, the pedal device 110. When the pedal device 110 is in the extended state (at this time, the telescopic seat 1112 in the pedal device 110 is in the 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 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 stepped structure, reduce the ground clearance of the vehicle 100, and facilitate the user to get on and off the vehicle. When the pedal device 110 is in the retracted state (at this time, the telescopic seat 1112 in the pedal device 110 is in the retracted state), the pedal body 113 in the pedal device 110 fits against the side skirt of the vehicle 100, so as to maintain the neat and smooth appearance of the vehicle 100 without affecting the passability of the vehicle 100.

[0044] The first gap distance L3 is greater than or equal to 100mm and less than or equal to 200mm, ensuring sufficient foothold for occupants when stepping on the pedal body 113 of the pedal device 110, thereby improving user comfort and satisfaction. Specifically, the first gap distance L3 can be 100mm, 120mm, 125mm, 130mm, 150mm, 160mm, 175mm, or 200mm, etc. In this example, the first gap distance L3 is 126.28mm. The second gap distance L4 is greater than or equal to 100mm and less than or equal to 150mm, effectively reducing the ground clearance of the vehicle 100 when the pedal device 110 is extended, thus facilitating entry and exit for different users and improving user-friendliness for shorter individuals. Specifically, 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 137mm.

[0045] Please refer to Figures 1-4. Figure 3 is a structural schematic diagram of the pedal device provided in some embodiments of this application when it is in the extended state, and Figure 4 is a structural schematic diagram of the pedal device provided in some embodiments of this application when it is in the retracted state. The pedal device 110 provided in this application may include, but is not limited to, a linkage assembly 111, a drive device 112, and a pedal body 113. Specifically, the drive device 112 is used to drive the first swing arm 1113 and / or the second swing arm 1114 in the linkage assembly 111. The pedal body 113 is fixed to the support arm 1115 in the linkage assembly 111. Under the drive of the drive device 112, the pedal body 113 can extend, retract, and rotate relative to the mounting seat 1111 in the linkage assembly 111.

[0046] Furthermore, the pedal device 110 includes a plurality of linkage assemblies 111. The plurality of linkage assemblies 111 are arranged along the length direction of the pedal body 113. In this embodiment, the pedal device 100 includes two linkage assemblies 111, which are arranged along the length direction of the pedal body 113, and the pedal device 100 is mounted on both sides of the vehicle 100. In this embodiment, increasing the number of linkage assemblies 111, for example, three or more, can effectively improve the load-bearing capacity of the pedal device 110, while also improving the smoothness of the pedal device 110's movement. In some other embodiments, the pedal device 100 includes one linkage assembly 111, which is arranged in the middle position of the pedal body 113 along the length direction of the pedal body 113. The pedal device 100 is installed corresponding to the position of a vehicle door, such as the tailgate, front left door, front right door, rear left door, and rear right door.

[0047] Furthermore, when the mounting base 1111 in the linkage assembly 111 is fixed to the chassis of the vehicle 100, if the telescopic seat 1112 in the linkage assembly 111 is in the extended state, the angle between the foot 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°, to prevent the user from easily slipping outwards when stepping on the foot surface M. Specifically, the angle between the foot 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°, and 5°, etc. In this embodiment, when the telescopic seat 1112 is in the extended state, the angle between the foot surface M of the pedal body 113 and the horizontal plane is 1.14°. When the telescopic seat 1112 in the linkage assembly 111 is in the retracted state, the angle between the foot 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 retraction concealment, overall aesthetics, and passability. Specifically, the angle between the foot 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 foot surface M of the pedal body 113 and the horizontal plane is 27.39°.

[0048] Optionally, the drive device 112 can be an electric motor. In this embodiment, the drive device 112 is connected to the first swing arm 1113 to drive the first swing arm 1113, and then, with the assistance of the second swing arm 1114, drives the telescopic seat 1112 to extend or retract relative to the mounting base 1111. In this embodiment, when the pedal device 110 is in the extended state (at this time, the telescopic seat 1112 is in the extended state), the pedal load borne by the pedal body 113 is difficult to be transmitted to the drive device 112, thereby protecting the drive device 112.

[0049] Please refer to Figures 1-9. Figure 5 is an exploded view of the linkage assembly provided in some embodiments of this application. Figure 6 is a structural diagram of the linkage assembly provided in some embodiments of this application in the retracted state. Figure 7 is a cross-sectional view of the linkage assembly provided in some embodiments of this application in the retracted state. Figure 8 is a structural diagram of the linkage assembly provided in some embodiments of this application in the extended state. Figure 9 is a cross-sectional view of the linkage assembly provided in some embodiments of this application in the extended state. The linkage assembly 111 provided in this 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 support arm 1115, and a linkage arm 1116. Specifically, along 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 separate, add-on 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 base 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 base 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. Along a 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 base 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 base 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 the sixth hinge point D6. The other end of the linkage arm 1116 is hinged to the support arm 1115 at the seventh hinge point D7. The linkage arm 1116 can drive the support arm 1115 to rotate around the fifth hinge point D5.

[0050] Specifically, along the second direction, the sixth hinge point D6 is further away 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. This arrangement allows the support arm 1115 to be rotated around the fifth hinge point D5 by the linkage arm 1116 during the extension and retraction of the telescopic seat 1112. More specifically, during the extension of the telescopic seat 1112, the linkage arm 1116 rotates the support arm 1115 outward around the fifth hinge point D5; during the retraction of the telescopic seat 1112, the linkage arm 1116 rotates the support arm 1115 inward around the fifth hinge point D5.

[0051] Furthermore, the support arm 1115 can rotate around the fifth hinge point D5 at an angle greater than or equal to 20° and less than or equal to 35°, so that the pedal body 113 fits against the vehicle skirt. Specifically, the angle at which the support arm 1115 can rotate around the fifth hinge point D5 can be 20°, 25°, 30°, or 35°, etc. In this embodiment, the angle at which the support arm 1115 can rotate around the fifth hinge point D5 is 26.3°.

[0052] Furthermore, 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 the retracted state, it occupies less chassis space in the vehicle 100.

[0053] When the telescopic base 1112 is in the extended or retracted state, the line connecting the second hinge point D2 and the fourth hinge point D4 forms an angle of 0° to 3° with the horizontal plane. Furthermore, the difference between the second center distance L2 and the first center distance L1 is greater than or equal to 6mm and less than or equal to 12mm. This design allows the telescopic base 1112 to have a certain swing amplitude and a relatively smooth swing trajectory, enabling it to extend smoothly from the chassis without colliding with protrusions on the ground due to excessive swing amplitude.

[0054] Specifically, when the pedal device 110 is installed on the chassis of the vehicle 100 and the telescopic seat 1112 is in the extended or retracted state, the angle formed by the line connecting the second hinge point D2 and the fourth hinge point D4 with 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.

[0055] Specifically, the difference between the second center distance L2 and the first center distance L1 can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, and 12mm, etc. In this embodiment, the difference between the second center distance L2 and the first center distance L1 is 9mm.

[0056] Furthermore, when the telescopic seat 1112 is in the retracted state, the line connecting the sixth hinge point D6 and the seventh hinge point D7, and the line connecting the sixth hinge point D6 and the third hinge point D3, form a first included angle α. The first included angle α is an acute angle. The magnitude of the first included angle α is greater than or equal to 0° and less than or equal to 10°. By ensuring that the sixth hinge point D6, the seventh hinge point D7, and the third hinge point D3 are located on the same straight line or approximately on the same straight line, the inertial load acting on the support arm 1115 during vehicle 100 operation can be prevented from causing the telescopic seat 1112 to automatically extend or be transmitted to the drive device 112. This increases the stability of the pedal device 110 in the retracted state. For example, when the pedal device 110 is subjected to external disturbances such as vibration or minor impacts, the first included angle α can create a relatively stable force transmission relationship between the sixth hinge point D6, the seventh hinge point D7, and the third hinge point D3, allowing the pedal device 110 to better resist these external disturbances and maintain a stable state.

[0057] Specifically, the size of the first included angle α can be 0°, 1.3°, 2.5°, 3.7°, 4.2°, 5°, 6.3°, 7.5°, 8.7°, 9.2°, and 10°, etc. In this embodiment, the size of the first included angle α is 4.19°.

[0058] Furthermore, 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 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 linkage assembly 111 can be made more compact and reliable when in the retracted state, thereby reducing the space occupied and ensuring the concealment of the retracted pedal device 110.

[0059] Furthermore, when the telescopic seat 1112 is in the retracted state, the line connecting the fourth hinge point D4 and the seventh hinge point D7, and the line connecting the sixth hinge point D6 and the fifth hinge point D5, form a second included angle β. The magnitude of the second included 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 connecting the fourth hinge point D4 and the sixth hinge point D6, and the line connecting the seventh hinge point D7 and the fifth hinge point D5, form a third included angle γ. The magnitude of the third included angle γ is greater than or equal to 0° and less than or equal to 5°. In this way, the linkage assembly 111 retracts compactly and reliably, while also facilitating the smooth outward rotation of the support arm 1115 via the linkage arm 1116 when extension is required.

[0060] Specifically, the second included angle β can be 0°, 0.7°, 1.3°, 2.5°, 3.8°, 4.2°, 5°, 5.7°, 6.3°, 7.5°, 8.8°, 9.2°, and 10°, etc. The third included angle γ can be 0°, 0.3°, 0.7°, 1.2°, 2.5°, 3.1°, 3.7°, 4.3°, 4.6°, and 5°, etc. In this embodiment, the second included angle β is 5.58°, and the third included angle γ is 0.75°.

[0061] Furthermore, when the telescopic seat 1112 is in the extended state, the line connecting the fifth hinge point D5 and the fourth hinge point D4, and the line connecting the fifth hinge point D5 and the third hinge point D3, form a sixth included angle g. This sixth included angle g is an acute angle. The magnitude of the sixth included angle g is greater than or equal to 0° and less than or equal to 10°. By ensuring that the fifth hinge point D5, the fourth hinge point D4, and the third hinge point D3 are located on the same straight line or approximately on the same straight line, it is possible to prevent the pedal load acting on the support arm 1115 from automatically retracting the telescopic seat 1112 or being transmitted to the drive device 112 when the pedal device 110 is in the extended state.

[0062] Specifically, the size of the sixth included angle g can be 0°, 1.3°, 2.5°, 3.7°, 4.2°, 5°, 6.3°, 7.5°, 8.7°, 9.2°, and 10°, etc. In this embodiment, the size of the sixth included angle g is 9.57°.

[0063] 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 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 linkage assembly 111 can be fully extended when in the extended state, thereby increasing the extension length and ensuring that the driver and passengers have sufficient footholds.

[0064] Furthermore, when the telescopic seat 1112 is in the extended state, the line connecting the sixth hinge point D6 and the seventh hinge point D7, and the line connecting the fourth hinge point D4 and the fifth hinge point D5, form a fourth included angle θ. The magnitude of the fourth included 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 connecting the sixth hinge point D6 and the fourth hinge point D4, and the line connecting the seventh hinge point D7 and the fifth hinge point D5, form a fifth included angle δ. The magnitude of the fifth included angle δ is greater than or equal to 45° and less than or equal to 55°. In this way, while the linkage assembly 111 is extended to its final position, it facilitates the smooth inward rotation of the support arm 1115 via the linkage arm 1116 when retraction is required.

[0065] Specifically, the magnitude of the fourth included angle θ can be 0°, 0.3°, 0.7°, 1.2°, 2.5°, 3.1°, 3.7°, 4.3°, 4.6°, and 5°, etc. The magnitude of the fifth included angle δ can be 45°, 45.3°, 45.7°, 46.2°, 47.5°, 48.1°, 48.7°, 49.3°, 49.6°, and 55°, etc. In this embodiment, the magnitude of the fourth included angle θ is 0.27°, and the magnitude of the fifth included angle δ is 49.92°.

[0066] In this embodiment, the second swing arm 1114 is generally Z-shaped. 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. The end of the first connecting portion 1114a away from the main body portion 1114b is hinged to the mounting base 1111 at a third hinge point D3. The end of the main body portion 1114b away from the first connecting portion 1114a is hinged to the telescopic base 1112 at a fourth hinge point D4. The 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.

[0067] 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, space can be effectively utilized, and the volume of the pedal device 110 when the telescopic seat 1112 is in the retracted state can be reduced, thereby ensuring the concealment of the retracted pedal device 110.

[0068] In this embodiment, the support arm 1115 is generally L-shaped. The support arm 1115 may include, but is not limited to, the connected third connecting part 1115a and the support part 1115b. The end of the third connecting part 1115a away from the support part 1115b is hinged to the linkage arm 1116 at the seventh hinge point D7, and the end of the third connecting part 1115a near the support part 1115b is hinged to the telescopic seat 1112 at the fifth hinge point D5.

[0069] In this embodiment, the telescopic seat 1112 may include, but is not limited to, a first molded base plate 1112a, a second molded base plate 1112b, and a side plate 1112c. The first molded base plate 1112a and the second molded base plate 1112b are spaced apart between the two side plates 1112c. One end of the side plate 1112c is hinged to the first swing arm 1113 at a second hinge point D2. The other end of the side plate 1112c is hinged to the support arm 1115 at a fifth hinge point D5. The structure between the two ends of the side plate 1112c is hinged to the second swing arm 1114 at a fourth hinge point D4. The space enclosed by the side plate 1112c, the first molded base plate 1112a, and the second molded base plate 1112b can accommodate part of the structure of the first swing arm 1113, part of the structure of the support arm 1115, and part of the structure of the second swing arm 1114. This method makes the relative positions of the components closer together, thereby reducing the volume of the pedal device 110 in the retracted state and improving space utilization. At the same time, it can also effectively reduce the impact of foreign objects such as dust, 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 vehicle 100 operation, thus improving the service life of the pedal device 110.

[0070] The linkage assembly 111 provided in this application includes a mounting base 1111; a telescopic base 1112, which is located below the mounting base 1111 along a first direction; a first swing arm 1113, one end of which is hinged to the mounting base 1111 at a first hinge point D1, and the other end of which is hinged to the telescopic base 1112 at a second hinge point D2; a second swing arm 1114, one end of which is hinged to the mounting base 1111 at a third hinge point D3, and the other end of which is hinged to the telescopic base 1112 at a fourth hinge point D4; wherein, along a second direction, the first... At least one of the 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; support arm 1115, the support arm 1115 is hinged to the telescopic seat 1112 at the fifth hinge point D5, and the fourth hinge point D4 is located between the fifth hinge point D5 and the second hinge point D2; linkage arm 1116, one end of the linkage arm 1116 is hinged to the other end of the second swing arm 1114 at the sixth hinge point D6, and the other end of the linkage arm 1116 is hinged to the support arm 1115 at the seventh hinge point D7; wherein, the linkage arm 1116 can drive the support arm 1115 to rotate around the fifth hinge point D5. In the technical solution of this application, during the extension of the telescopic seat 1112 relative to the mounting seat 1111, the support arm 1115 flips outward as the telescopic seat 1112 extends, so that the pedal body 113 fixed to the support arm 1115 has sufficient extension length; during the retraction of the telescopic seat 1112 relative to the mounting seat 1111, the support arm 1115 flips inward as the telescopic seat 1112 retracts, so that the pedal body 113 fixed to the support arm 1115 can fit against the vehicle skirt. In this way, the linkage assembly 111 enables the pedal device 110 installed on the new energy vehicle to have both sufficient extension length and ensure concealment when retracted.
