Description

Technical Field

[0002] Due to their high reliability and excellent load-bearing capacity, four-link electric running boards are widely used in many vehicles with taller chassis to facilitate entry and exit. However, for new energy SUVs, the proximity of the battery pack to the vehicle's side rails limits the installation space for the electric running boards. This makes it difficult to achieve both sufficient extended length and concealed retraction when installed on new energy vehicles. Utility Model Content

[0041] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0042] 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 top refers to the direction indicated by the positive direction of the Z axis, the bottom refers to the direction indicated by the negative direction of the Z axis, the outward refers to the direction indicated by the positive direction of the Y axis, and the inward refers to the direction indicated by the negative direction of the Y axis.

[0043] The connecting rod assembly provided in the present application includes a mounting seat; a telescopic seat, wherein the telescopic seat is located below the mounting seat along a first direction; a first swing arm, wherein one end of the first swing arm is hinged to the mounting seat at a first hinge point, and the other end of the first swing arm is hinged to the telescopic seat at a second hinge point; a second swing arm, wherein one end of the second swing arm is hinged to the mounting seat at a third hinge point, and the other end of the second swing arm is hinged to the telescopic seat at a fourth hinge point; wherein, along the second direction, at least one of the first swing arm and the second swing arm can drive the telescopic seat to extend and retract relative to the mounting seat. The second direction is perpendicular to the first direction; a support arm, the support arm and the telescopic seat are hinged at a fifth hinge point, and the fourth hinge point is located between the fifth hinge point and the second hinge point; a linkage arm, one end of the linkage arm and the other end of the second swing arm are hinged at a sixth hinge point, and the other end of the linkage arm is hinged to the support arm at a seventh hinge point; wherein, during the extension of the telescopic seat, the linkage arm drives the support arm to flip outward around the fifth hinge point; and during the retraction of the telescopic seat, the linkage arm drives the support arm to flip inward around the fifth hinge point. In the technical solution of the present application, when the telescopic seat is extended relative to the mounting seat, the support arm flips outward as the telescopic seat extends, so that the pedal body fixed to the support arm has sufficient extension length; when the telescopic seat is retracted relative to the mounting seat, the support arm flips inward as the telescopic seat retracts, so that the pedal body fixed to the support arm can fit the vehicle skirt. In this way, the connecting rod assembly can ensure that the pedal device installed on the new energy vehicle has both sufficient extension length and retraction concealment.

[0044] Please refer to Figure 1-Figure 2 , Figure 1 is 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 21 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), a first gap distance L3 exists between the pedal body 113 in the pedal device 110 and the side skirt of the vehicle 100 along a first direction, and a second gap distance L4 exists between the pedal body 113 in the pedal device 110 and the side skirt of the vehicle 100 along a second direction, thereby forming a stepped structure, reducing the ground clearance of the vehicle 100 and facilitating the user's boarding and alighting. 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 against the side skirt of the vehicle 100, thereby maintaining a neat and smooth appearance of the vehicle 100 without affecting the vehicle's passability.

[0045] The first clearance distance L3 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 L3 is 126.28 mm. The second clearance distance L4 is greater than or equal to 100 mm and less than or equal to 150 mm. This effectively reduces the ground clearance of the vehicle 100 when the pedal assembly 110 is extended, facilitating entry and exit for various users and improving vehicle-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 L4 is 137 mm.

[0046] 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 41 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 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. Specifically, under the drive of the driving device 112, the pedal body 113 can be extended and tilted relative to the mounting seat 1111 in the connecting rod assembly 111.

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

[0048] Furthermore, when the mounting base 1111 of the connecting rod assembly 111 is fixed to the chassis of the vehicle 100, if the telescopic base 1112 of the connecting rod assembly 111 is in the extended position, the angle between the footrest 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°, thereby preventing the user from slipping when stepping on the footrest surface M. Specifically, the angle between the footrest 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 base 1112 is in the extended position, the angle between the footrest surface M of the pedal body 113 and the horizontal plane is 1.14°. When the telescopic seat 1112 in the connecting rod assembly 111 is retracted, 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°, thereby better fitting 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°, or 40°, etc. In this embodiment, when the telescopic seat 1112 is retracted, the angle between the pedal surface M of the pedal body 113 and the horizontal plane is 27.39°.

[0049] 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 (at which point the telescopic seat 1112 is also in the extended state), the pedaling load borne by the pedal body 113 is less likely to be transmitted to the drive device 112, thereby protecting the drive device 112.

[0050] Please refer to Figures 1-9 , 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 structural diagram of a 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 in a retracted state, Figure 8 is a schematic structural diagram of a connecting rod assembly provided in some embodiments of the present application when in an extended state. Figure 9A cross-sectional view of the connecting rod assembly provided in some embodiments of the present application in an extended state. The connecting rod assembly 111 provided herein 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 a first direction, the telescopic base 1112 is located below the mounting base 1111. In this embodiment, the first and second swing arms 1113, 1114 can be attached to the chassis of the vehicle 100 via the mounting base 1111, allowing the pedal device 110 to be installed and used as a separately attachable accessory. In other embodiments, the first and second swing arms 1113, 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. The second direction is perpendicular to the first direction. In this embodiment, the first swing arm 1113 drives the telescopic base 1112 to extend and retract relative to the mounting base 1111. The support arm 1115 is hinged to the telescopic base 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. 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 than the fourth hinge point D4, and the seventh hinge point D7 is closer to the second hinge point D2 than the fifth hinge point D5. Along the first direction, the seventh hinge point D7 is located above the fifth hinge point D5. This layout allows the support arm 1115 to be driven by the linkage arm 1116 to rotate about the fifth hinge point D5 as the telescopic base 1112 extends and retracts. More specifically, when the telescopic base 1112 extends, the linkage arm 1116 drives the support arm 1115 to rotate outward about the fifth hinge point D5; when the telescopic base 1112 retracts, the linkage arm 1116 drives the support arm 1115 to rotate inward about the fifth hinge point D5.

[0052] Furthermore, the support arm 1115 can rotate about the fifth hinge point D5 to an angle greater than or equal to 20° and less than or equal to 35°, so that the pedal body 113 fits snugly on the vehicle skirt. Specifically, the support arm 1115 can rotate about the fifth hinge point D5 to an angle of 20°, 25°, 30°, 35°, etc. In this embodiment, the support arm 1115 can rotate about the fifth hinge point D5 to a 26.3° angle.

[0053] Furthermore, the distance between the first hinge point D1 and the second hinge point D2 is a first center distance L1. The distance between the third hinge point D3 and the fourth hinge point D4 is a 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 in the retracted state, it occupies less chassis space of the vehicle 100.

[0054] 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 6 mm and less than or equal to 12 mm. This ensures that the telescopic base 1112 has a certain swing amplitude and a relatively smooth arc trajectory, allowing the telescopic base 1112 to smoothly extend from the chassis while preventing it from colliding with protruding objects on the ground due to excessive swing amplitude.

[0055] Specifically, when the pedal device 110 is mounted on the chassis of the vehicle 100 and the telescopic base 1112 is in the extended state or the retracted state, the angle formed by the line connecting 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°, 3°, etc.

[0056] Specifically, the difference between the second center distance L2 and the first center distance L1 can 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] 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 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 locating the sixth hinge point D6, the seventh hinge point D7, and the third hinge point D3 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 automatically extending the telescopic seat 1112 or being transferred to the drive device 112. This approach enhances the stability of the pedal assembly 110 in the retracted state. For example, when the pedal assembly 110 is subjected to external disturbances such as vibration or minor impact, the first 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, enabling the pedal assembly 110 to better withstand these external disturbances and maintain stability.

[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] 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 form the four corner points of the first quadrilateral Q1. Within 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 diagonally 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. This makes the connecting rod assembly 111 more compact and reliable when in the retracted state, thereby reducing space usage and ensuring the retracted pedal device 110 is discreet.

[0060] Furthermore, when the telescopic base 1112 is retracted, 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 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 base 1112 is retracted, 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 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 manner, the link assembly 111 can be retracted compactly and reliably, while also facilitating smooth outward rotation of the support arm 1115 via the linkage arm 1116 when needed.

[0061] Specifically, the second 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 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 angle β is 5.58°, and the third angle γ is 0.75°.

[0062] 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 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 locating the fifth hinge point D5, the fourth hinge point D4, and the third hinge point D3 on the same straight line, or approximately on the same straight line, the pedal load acting on the support arm 1115 can be prevented from automatically retracting the telescopic seat 1112 or being transmitted to the drive device 112 when the pedal assembly 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°, or 10°, etc. In this embodiment, the sixth angle g is 9.57°.

[0064] Furthermore, when the telescopic seat 1112 is in the extended position, the sixth hinge point D6, the seventh hinge point D7, the fourth hinge point D4, and the fifth hinge point D5 form the four corner points of the second quadrilateral Q2. Within 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 diagonally 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. This allows the connecting rod assembly 111 to fully extend when in the extended position, thereby increasing the extended length and ensuring sufficient footholds for the driver and passengers.

[0065] Furthermore, when the telescopic base 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 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 base 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 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 manner, while the connecting rod assembly 111 is fully extended, it facilitates the smooth inward rotation of the support arm 1115 via the linkage arm 1116 when retraction is required.

[0066] Specifically, the fourth angle θ can be 0°, 0.3°, 0.7°, 1.2°, 2.5°, 3.1°, 3.7°, 4.3°, 4.6°, or 5°, etc. The fifth angle δ can be 45°, 45.3°, 45.7°, 46.2°, 47.5°, 48.1°, 48.7°, 49.3°, 49.6°, or 55°, etc. In this 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 generally Z-shaped. The second swing arm 1114 may include, but is not limited to, a first connecting portion 1114a, a main portion 1114b, and a second connecting portion 1114c. Specifically, the main portion 1114b is connected between the first connecting portion 1114a and the second connecting portion 1114c. The end of the first connecting portion 1114a, distal to the main portion 1114b, is hinged to the mounting base 1111 at a third hinge point D3. The end of the main portion 1114b, distal to 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, distal to the main 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 slot 1114d. When the telescopic seat 1112 is retracted, the linkage arm 1116 is accommodated in the receiving slot 1114d. This effectively utilizes space and reduces the volume of the pedal assembly 110 when the telescopic seat 1112 is retracted, thereby ensuring that the pedal assembly 110 remains concealed when retracted.

[0069] In this embodiment, the support arm 1115 is generally L-shaped. The support arm 1115 may include, but is not limited to, a third connecting portion 1115a and a supporting portion 1115b. The end of the third connecting portion 1115a distal from the supporting portion 1115b is hingedly connected to the linkage arm 1116 at a seventh hinge point D7. The end of the third connecting portion 1115a proximal to the supporting portion 1115b is hingedly connected to the telescopic base 1112 at a fifth hinge point D5.

[0070] 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 and connected 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. 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 plates 1112c, the first molded base plate 1112a, and the second molded base plate 1112b can accommodate a portion of the structure of the first swing arm 1113, a portion of the structure of the support arm 1115, and a portion of the structure of the second swing arm 1114. This arrangement allows for a closer relationship between the various components, thereby reducing the volume of the retracted pedal assembly 110 and improving space utilization. It also effectively reduces the impact of foreign matter such as dust, accumulated water, and flying rocks on the first swing arm 1113, second swing arm 1114, support arm 1115, and linkage arm 1116 during vehicle 100 operation, thereby extending the service life of the pedal assembly 110.

[0071] The connecting rod assembly 111 provided in the present application includes a mounting seat 1111; a telescopic seat 1112, wherein the telescopic seat 1112 is located below the mounting seat 1111 along the first direction; a first swing arm 1113, wherein 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, wherein 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, along 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 be relatively mounted. The mounting seat 1111 extends and retracts; the second direction is perpendicular to the first direction; the support arm 1115, the support arm 1115 and the telescopic seat 1112 are hinged 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; the linkage arm 1116, one end of the linkage arm 1116 and the other end of the second swing arm 1114 are hinged at the sixth hinge point D6, and the other end of the linkage arm 1116 and the support arm 1115 are hinged at the seventh hinge point D7; wherein, during the extension of the telescopic seat 1112, the linkage arm 1116 drives the support arm 1115 to flip outward around the fifth hinge point D5; during the retraction of the telescopic seat 1112, the linkage arm 1116 drives the support arm 1115 to flip inward around the fifth hinge point D5. In the technical solution of this application, as the telescopic seat 1112 extends relative to the mounting seat 1111, the support arm 1115 simultaneously tilts outward as the telescopic seat 1112 extends, allowing the pedal body 113 fixed to the support arm 1115 to have sufficient extension length. As the telescopic seat 1112 retracts relative to the mounting seat 1111, the support arm 1115 simultaneously tilts inward as the telescopic seat 1112 retracts, allowing the pedal body 113 fixed to the support arm 1115 to fit snugly against the vehicle skirt. In this way, the connecting rod assembly 111 ensures that the pedal device 110 installed on a new energy vehicle has both sufficient extension length and is concealed when retracted.
