For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] In the related art, the boarding step is prone to shaking in the deployed and retracted positions, resulting in insufficient overall pedaling stability. The structural stability of the boarding step is poor, and the boarding step may shake during deployment, affecting the pedaling stability of passengers and may cause safety risks such as passengers falling.

[0027] To solve the above problems, refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a connecting rod assembly 100 , which includes a fixing member 110 , a first connecting rod 120 , a second connecting rod 130 , a pedal connecting rod 140 , a first movable member 150 and a second movable member 160 .

[0028] Specifically, combined Figure 2 and Figure 3 As shown, the first connecting rod 120 is provided with a first connecting shaft 121 and a second connecting shaft 122, and one end of the first connecting rod 120 is hinged to the fixing member 110 through the first connecting shaft 121. One end of the second connecting rod 130 is hinged to the fixing member 110. One end of the pedal connecting rod 140 is hinged to one end of the first connecting rod 120 away from the fixing member 110, and the other end of the pedal connecting rod 140 is hinged to one end of the second connecting rod 130 away from the fixing member 110, so that the pedal connecting rod 140, the fixing member 110, the second connecting rod 130 and the first connecting rod 120 together form a frame structure.

[0029] In this embodiment, one end of the first movable member 150 is hinged to the fixed member 110 via a third connecting shaft 151 . One end of the second movable member 160 is hinged to the end of the first movable member 150 away from the fixed member 110 through the fourth connecting shaft 161, and the end of the second movable member 160 away from the first movable member 150 is hinged to the first connecting rod 120 through the second connecting shaft 122. Accordingly, the first movable member 150 is an active driving member, which makes the first movable member 150 rotate around the third connecting shaft 151. When the first movable member 150 is driven, the second movable member 160 and the first connecting rod 120 are driven to move. The fixed member 110, the first connecting rod 120, the second connecting rod 130 and the pedal connecting rod 140 of the connecting rod assembly 100 are interconnected to form a frame structure. The first movable member 150 and the second movable member 160 adjust and limit the rotational position between the fixed member 110 and the first connecting rod 120, so that the relative position of the pedal connecting rod 140 and the fixed member 110 can be adjusted.

[0030] It can be understood that the connecting rod assembly 100 has a self-locking position. When in the self-locking position, the central axis of the second connecting shaft 122, the central axis of the third connecting shaft 151 and the central axis of the fourth connecting shaft 161 are arranged in parallel and are in the same plane, so that the connecting rod assembly 100 can be in the self-locking position. At this time, the central axes of the second connecting shaft 122, the third connecting shaft 151 and the fourth connecting shaft 161 are parallel to each other and are in the same plane. When the connecting rod assembly 100 is not driven by external force, the connecting rod assembly 100 can be locked in the self-locking position. Since the central axes of the second connecting shaft 122, the third connecting shaft 151 and the fourth connecting shaft 161 are in the same plane, the connecting rod assembly 100 is in a balanced state, which reduces the shaking of the connecting rod assembly 100 and improves the stability of the connecting rod assembly 100.

[0031] Exemplarily, the axis of the fourth connecting shaft 161 is C1, the axis of the third connecting shaft 151 is C2, the axis of the second connecting shaft 122 is C3, and the axis of the first connecting shaft 121 is C4. When the connecting rod assembly 100 is in the self-locking position, the direction of the force F1 of the connecting rod assembly 100 itself is the direction of the line connecting the fourth connecting shaft 161, the third connecting shaft 151 and the second connecting shaft 122. No matter how the value of the force F1 of the connecting rod assembly 100 changes, the force direction of the first movable part 150 as the active part is always in the rotation direction of the third connecting shaft 151, so that the first movable part 150 remains stationary and will not cause the connecting rod assembly 100 to move on its own. Therefore, the connecting rod assembly 100 can be self-locked in this position, so that the connecting rod assembly 100 remains locked and motionless.

[0032] It should be noted that the reference Figure 1 and Figure 3As shown, the connecting rod assembly 100 has a first direction X and a second direction Y, wherein the first direction X and the second direction Y are arranged perpendicularly to each other. Exemplarily, the first direction X is taken as the length direction of the connecting rod assembly 100, and the second direction Y is taken as the height direction of the connecting rod assembly 100. It can be understood that the above definitions are only for the purpose of facilitating the understanding of the relative positional relationship of the various parts in the connecting rod assembly 100, and should not be construed as limiting the present application.

[0033] In one embodiment, optionally, Figure 1 and Figure 2 As shown, the self-locking position includes a first self-locking position. When in the first self-locking position, the third connecting shaft 151 is located between the second connecting shaft 122 and the fourth connecting shaft 161. The first connecting shaft 121, the second connecting shaft 122 and the fourth connecting shaft 161 together constitute a triangular structure. In other words, when the connecting rod assembly 100 is in the first self-locking position, the connecting rod assembly 100 is in an unfolded state, the fixing member 110 and the pedal connecting rod 140 are unfolded through the second connecting rod 130 and the first connecting rod 120 and can maintain an overall stable state. The first connecting shaft 121, the second connecting shaft 122 and the fourth connecting shaft 161 constitute a relatively stable triangular structure. When the first movable member 150 is not actively driven, the connecting rod assembly 100 is self-locked to prevent the connecting rod assembly 100 from shaking or swaying in the first self-locking position, so as to improve the self-locking stability of the connecting rod assembly 100 in the first self-locking position.

[0034] Alternatively, if Figure 3 As shown, the self-locking position includes a second self-locking position. When in the second self-locking position, the fourth connecting shaft 161 is located between the second connecting shaft 122 and the third connecting shaft 151, and the first connecting shaft 121, the second connecting shaft 122 and the third connecting shaft 151 together constitute a triangular structure. Accordingly, when the connecting rod assembly 100 is in the second self-locking position, the connecting rod assembly 100 is in a retracted state, and the pedal connecting rod 140 moves to a position close to the fixing member 110. At this time, the fourth connecting shaft 161 is located between the second connecting shaft 122 and the third connecting shaft 151, and the first connecting shaft 121, the second connecting shaft 122 and the third connecting shaft 151 constitute a relatively stable triangular structure. In the absence of active driving of the first movable member 150, the connecting rod assembly 100 is self-locked to prevent the connecting rod assembly 100 from shaking or swaying in the second self-locking position, so as to improve the self-locking stability of the connecting rod assembly 100 in the second self-locking position. Exemplarily, the connecting rod assembly 100 is in the second self-locking position, and the pedal connecting rod 140 is in contact with the fixing member 110 .

[0035] Optionally, combined Figure 1 and Figure 3As shown, the connecting rod assembly 100 switches between the first self-locking position and the second self-locking position, and the pedal connecting rod 140 can be close to the fixing member 110 or away from the fixing member 110, that is, the connecting rod assembly 100 switches between the deployed state and the retracted state. When the connecting rod assembly 100 switches from the deployed state to the retracted state, the pedal connecting rod 140 gradually approaches the fixing member 110, and when the connecting rod assembly 100 switches from the retracted state to the deployed state, the pedal connecting rod 140 gradually moves away from the fixing member 110.

[0036] In one embodiment, optionally, Figure 2 As shown, the first connecting rod 120 is hinged to the pedal connecting rod 140 through the fifth connecting shaft 123, and the second connecting shaft 122 is located between the first connecting shaft 121 and the fifth connecting shaft 123, so that the first connecting rod 120 and the pedal connecting rod 140 can move relative to each other through the fifth connecting shaft 123. The position of the second connecting shaft 122 is located between the first connecting shaft 121 and the fifth connecting shaft 123, and the second movable member 160 can drive the first connecting rod 120 to move through the second connecting shaft 122, so that the connecting rod assembly 100 can switch between the deployed state and the retracted state.

[0037] Based on any of the above embodiments, optionally, refer to Figure 1 and Figure 2 As shown, the fixing member 110 includes a fixing portion 111 and an extending portion 112, the fixing portion 111 and the extending portion 112 are integrally arranged, and the fixing portion 111 and the pedal connecting rod 140 are arranged in parallel, that is, when the connecting rod assembly 100 switches between the deployed state and the retracted state, the fixing portion 111 of the fixing member 110 and the pedal connecting rod 140 always remain parallel, and the extending portion 112 of the fixing portion 111 is connected to the third connecting shaft 151, so that the extending portion 112 is hinged to the first movable member 150 through the third connecting shaft 151.

[0038] In summary, the fixed part 110, the first connecting rod 120, the second connecting rod 130 and the pedal connecting rod 140 of the connecting rod assembly 100 are interconnected to form a frame structure, and the first movable part 150 and the second movable part 160 adjust and limit the rotational position between the fixed part 110 and the first connecting rod 120, so that the relative position of the pedal connecting rod 140 and the fixed part 110 can be adjusted, and the connecting rod assembly 100 can be in a self-locking position. At this time, the central axes of the second connecting shaft 122, the third connecting shaft 151, and the fourth connecting shaft 161 are parallel to each other and are in the same plane. The connecting rod assembly 100 can be locked in the self-locking position, so that the connecting rod assembly 100 is in a balanced state, the shaking of the connecting rod assembly 100 is reduced, the stability of the connecting rod assembly 100 is improved, and the safety performance of the connecting rod assembly 100 is ensured.

[0039] In the related art, a locking member is used to lock the boarding pedal in the deployed position and the retracted position to ensure that the boarding pedal is in a stable state. The inventor of the present application found in the research that the locking member can only lock the movement of the first movable member 150 in a certain direction, but the locking member cannot completely lock the first movable member 150 in a locked state, which will cause the pedal of the pedal device 200 to shake or swing.

[0040] To solve the above problems, refer to Figures 4 to 6 As shown, the present application further provides a pedal device 200 , which includes the connecting rod assembly 100 described in the above embodiment, and the pedal device 200 also includes a pedal member 230 and a housing assembly 220 .

[0041] Specifically, combined Figure 4 and Figure 5 As shown, the pedal member 230 is installed on the pedal connecting rod 140, and the pedal member 230 is used for passengers to step on and provide a support position to facilitate passengers to get on and off the vehicle. The shell assembly 220 defines a receiving cavity and is provided with an opening 221. The connecting rod assembly 100 is arranged in the receiving cavity, that is, the shell assembly 220 can cover the connecting rod assembly 100, and play a role in wrapping and protecting the connecting rod assembly 100, so that the pedal connecting rod 140 can be accommodated in the opening 221 or the pedal connecting rod 140 extends from the opening 221, so that the pedal connecting rod 140 can be extended or retracted through the opening 221 of the shell assembly 220, avoiding affecting and hindering the active path trajectory of the pedal connecting rod 140. Exemplarily, when the pedal connecting rod 140 can be accommodated in the opening 221, the pedal connecting rod 140 can close the opening 221.

[0042] In one embodiment, optionally, Figure 6 As shown, the pedal device 200 further includes a driving assembly 210, which is connected to the first movable member 150, and the driving assembly 210 can drive the first movable member 150 to rotate about the third connecting shaft 151. Accordingly, the driving assembly 210 can drive the first movable member 150 to rotate about the third connecting shaft 151, so that the first movable member 150 drives the first connecting rod 120 to move through the second movable member 160, thereby expanding and retracting the pedal member 230 of the connecting rod assembly 100. Exemplarily, the driving assembly 210 is provided with a driving motor.

[0043] Optionally, combined Figure 3 and Figure 6As shown, the first movable member 150 can rotate around the third connecting shaft 151 along a first rotation direction or a second rotation direction, and the first rotation direction is opposite to the second rotation direction. Exemplarily, the first rotation direction is clockwise and the second rotation direction is counterclockwise.

[0044] In summary, the pedal device 200 is installed with a pedal member 230 for passengers to step on and provides a support position to facilitate passengers to get on and off the vehicle. The shell assembly 220 can cover the connecting rod assembly 100 to wrap and protect the connecting rod assembly 100. The pedal connecting rod 140 is extended or retracted through the opening 221 of the shell assembly 220 to avoid affecting and obstructing the active path trajectory of the pedal connecting rod 140. The driving assembly 210 can drive the first movable member 150 to expand and retract the pedal member 230 of the connecting rod assembly 100, and when the driving assembly 210 loses support and connection to the connecting rod assembly 100, the connecting rod assembly 100 can be in a self-locking state to prevent the pedal member 230 from falling off or falling from the pedal device 200, thereby improving the safety performance of the pedal device 200.

[0045] An embodiment of the present invention further provides a vehicle, which may be an MPV, SUV, sedan, crossover passenger car or truck, bus, special vehicle, etc., including the pedal device 200 described in the above embodiments. The vehicle including the pedal device 200 has all the beneficial effects of the pedal device 200, which will not be described in detail here.

[0046] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
