[0043] Reference Figure 1 and Figure 2 As shown in

[0044] Specifically, combined with Figure 2 and Figure 3As shown, the fixing member 110 includes a fixing portion 111, a first extending portion 112 and a second extending portion 113, one end of the fixing portion 111 is connected with the second extending portion 113 through the first extending portion 112, and a bending portion 114 is formed at the connection position of the first extending portion 112 and the second extending portion 113. One end of the first connecting rod 120 is hingedly connected with one end of the fixing portion 111 close to the first extending portion 112. One end of the second connecting rod 130 is hingedly connected with one end of the fixing portion 111 away from the first extending portion 112. One end of the pedal connecting rod 140 is hingedly connected with 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 hingedly connected with one end of the second connecting rod 130 away from the fixing member 110. One end of the self-locking member is hingedly connected with the first connecting rod 120, and the other end of the self-locking member away from the first connecting rod 120 is hingedly connected with the bending portion 114, so that the position of the bending portion 114 towards the self-locking member forms a protruding structure. The fixing portion 111, the first connecting rod 120, the second connecting rod 130 and the pedal connecting rod 140 are connected with each other to form a frame structure, and the relative positions of the pedal connecting rod 140 and the fixing member 110 can be adjusted.

[0045] The connecting rod assembly 100 has at least a first self-locking position. When in the first self-locking position, the self-locking member is arranged in line with the second extending portion 113, and correspondingly, the connecting rod assembly 100 can be locked in the first self-locking position, thereby being in a balanced state and improving the stability of the connecting rod assembly 100. The connection position of the first extending portion 112 and the second extending portion 113 forms a bending portion 114, and the self-locking member is hingedly connected with the bending portion 114. On the one hand, the in-line arrangement of the self-locking member and the second extending portion 113 protects the self-locking member from being stuck during movement. On the other hand, the position of the bending portion 114 forms a space for installation of the connecting rod assembly 100, reduces the space occupied by the first extending portion 112 and the second extending portion 113, and improves the space utilization, thereby reasonably utilizing the limited space on the vehicle and improving the structural adaptability of the connecting rod assembly 100.

[0046] It should be noted that, as shown in Figure 1 and Figure 3 , 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. For example, the first direction X is in the length direction of the connecting rod assembly 100, and the second direction Y is in the height direction of the connecting rod assembly 100. It should be understood that the above definitions are only for the purpose of understanding the relative positional relationship of the parts in the connecting rod assembly 100, and should not be construed as a limitation on the present application.

[0047] Optionally, with reference to Figure 1 As shown, when in the first self-locking position, the opposite ends of the pedal connecting rod 140 are respectively arranged perpendicularly to the first connecting rod 120 and the second connecting rod 130, and the first connecting rod 120 and the second connecting rod 130 are arranged in parallel, so that the first connecting rod 120, the second connecting rod 130, the pedal connecting rod 140 and the fixed part 111 can form a square frame structure, the pedal connecting rod 140 can be self-locked in position in the square frame structure, the extension path of the pedal connecting rod 140 is ensured, and the pedal connecting rod 140 has sufficient spacing from the fixed part 111, so as to facilitate the user to use the pedal connecting rod 140 for foot support and improve the user experience.

[0048] In one embodiment, optionally, the first connecting rod 120 is provided with a first connecting shaft 121 and a second connecting shaft 122, and the self-locking part includes a first movable part 150 and a second movable part 160, and the first movable part 150 and the second movable part 160 are activated to realize the self-locking function.

[0049] In this embodiment, one end of the first movable part 150 is hinged to the fixed part 111 through a third connecting shaft 151. One end of the second movable part 160 is hinged to one end of the first movable part 150 away from the fixed part 111 through a fourth connecting shaft 161, and the other end of the second movable part 160 away from the first movable part 150 is hinged to the first connecting rod 120 through the second connecting shaft 122. The first movable part 150 is a driving part, which rotates about the third connecting shaft 151 to drive the second movable part 160 and the first connecting rod 120 to move. 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 connected to form a frame structure, and the first movable part 150 and the second movable part 160 adjust and limit the rotation 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.

[0050] In the embodiment, when the self-locking piece is self-locked, 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 in the same plane. It can be understood that the linkage 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 in the same plane, which can enable the linkage assembly 100 to 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 in the same plane, and the linkage assembly 100 can be locked in the self-locking position without being driven by an external force. 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 linkage assembly 100 is in a balanced state, reducing the shaking of the linkage assembly 100 and improving the stability of the linkage assembly 100.

[0051] For example, 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 linkage assembly 100 is in the self-locking position, the direction of the force F1 acting on the linkage assembly 100 is the direction of the line connecting the fourth connecting shaft 161, the third connecting shaft 151 and the second connecting shaft 122. Regardless of the value of the force F1 acting on the linkage assembly 100, the direction of the force acting on the first movable piece 150 as the driving piece is always towards the rotation direction of the third connecting shaft 151, so that the first movable piece 150 remains stationary and does not cause the linkage assembly 100 to move by itself. Therefore, the linkage assembly 100 can be self-locked at this position, keeping the linkage assembly 100 locked and stationary.

[0052] Optionally, the first connecting shaft 121 is located at the fixed part 111, the third connecting shaft 151 is located at the bent part 114, and the fixed part 111 is arranged in parallel with the pedal linkage 140, i.e., the fixed part 111 of the fixed piece 110 and the pedal linkage 140 always remain parallel when the linkage assembly 100 is switched between the unfolded state and the recovered state. The fixed part 111 is connected with the first connecting shaft 121, so that the bent part 114 is hingedly connected with the first movable piece 150 through the third connecting shaft 151.

[0053] In one embodiment, optionally, as Figure 1 and Figure 2As shown, the self-locking part includes a first self-locking position when self-locked, and 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, and the first connecting shaft 121, the second connecting shaft 122 and the fourth connecting shaft 161 jointly form a triangular structure, in other words, when the linkage assembly 100 is in the first self-locking position, the linkage assembly 100 is in an unfolded state, and the fixing member 110 and the pedal linkage 140 are unfolded by the second linkage 130 and the first linkage 120 and can be kept in an overall stable state, and the first connecting shaft 121, the second connecting shaft 122 and the fourth connecting shaft 161 form a relatively stable triangular structure, so that the linkage assembly 100 is self-locked without active driving of the first movable member 150, preventing the linkage assembly 100 from shaking or swinging in the first self-locking position, so as to improve the self-locking stability of the linkage assembly 100 in the first self-locking position.

[0054] Optionally, as shown in Figure 3 As shown, the self-locking part includes a second self-locking position when self-locked, and 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 jointly form a triangular structure, and correspondingly, when the linkage assembly 100 is in the second self-locking position, the linkage assembly 100 is in a retracted state, and the pedal linkage 140 moves to a position close to the fixing member 110, at which 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 form a relatively stable triangular structure, so that the linkage assembly 100 is self-locked without active driving of the first movable member 150, preventing the linkage assembly 100 from shaking or swinging in the second self-locking position, so as to improve the self-locking stability of the linkage assembly 100 in the second self-locking position. Illustratively, the linkage assembly 100 is in the second self-locking position, and the pedal linkage 140 abuts against the fixing member 110.

[0055] Optionally, in combination with Figure 1 and Figure 3 As shown, the linkage assembly 100 switches between the first self-locking position and the second self-locking position, and the pedal linkage 140 can be close to or away from the fixing member 110, that is, the linkage assembly 100 switches between the unfolded state and the retracted state, and during the process of switching the linkage assembly 100 from the unfolded state to the retracted state, the pedal linkage 140 gradually approaches the fixing member 110, and during the process of switching the linkage assembly 100 from the retracted state to the unfolded state, the pedal linkage 140 gradually moves away from the fixing member 110.

[0056] In one embodiment, optionally, asFigure 2 As shown, the first connecting rod 120 is hinged with the pedal connecting rod 140 through a fifth connecting shaft 123, 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 are relatively movable 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 second movable element 160 can drive the first connecting rod 120 to move, so as to switch the connecting rod assembly 100 between the unfolded state and the retracted state.

[0057] In summary, the fixed element 110, the first connecting rod 120, the second connecting rod 130 and the pedal connecting rod 140 of the connecting rod assembly 100 are connected to form a frame structure, the first movable element 150 and the second movable element 160 adjust and limit the rotation position between the fixed element 110 and the first connecting rod 120, so that the relative position of the pedal connecting rod 140 and the fixed element 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 in the same plane, the connecting rod assembly 100 can be locked at the self-locking position, so as to make the connecting rod assembly 100 in a balanced state, reduce the shaking of the connecting rod assembly 100, improve the stability of the connecting rod assembly 100, and ensure the safety performance of the connecting rod assembly 100.

[0058] Reference Figures 4 to 6 As shown, the pedal device 200 provided by the present application also includes the connecting rod assembly 100 described in the above embodiments, and further includes a pedal element 230 and a housing assembly 220.

[0059] Specifically, in combination with Figure 4 and Figure 5 As shown, the pedal element 230 is installed on the pedal connecting rod 140, and is used for passenger stepping and providing a supporting position to facilitate passengers to get on and off the vehicle. The housing assembly 220 defines a containing cavity and is provided with an opening 221, and the connecting rod assembly 100 is arranged in the containing cavity, that is, the housing assembly 220 can wrap the connecting rod assembly 100, so as to wrap and protect 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 can be extended from the opening 221, so as to facilitate the pedal connecting rod 140 to be extended or retracted through the opening 221 of the housing assembly 220, and avoid affecting and hindering the movement path of the pedal connecting rod 140. When the pedal connecting rod 140 is accommodated in the opening 221, the pedal element 230 closes the opening 221.

[0060] Exemplarily, the shell assembly 220 is provided with a footrest part away from one side of the pedal part 230, the footrest part forms an extended plane, the footrest part can provide a support position for the user to step on, and the footrest part and the pedal part 230 together provide a support position for the user to step on, thereby ensuring the convenience of the user to get on and off the vehicle, and further enabling the shell assembly 220 to also provide a support position for the user to step on.

[0061] Exemplarily, the length d of the pedal part 230 and the length H of the pedal connecting rod 140 satisfy: 0.6H≤d≤H, in other words, the length d of the pedal part 230 is less than or equal to the length H of the pedal connecting rod 140, so that the pedal part 230 is located on the pedal connecting rod 140 or inside the pedal connecting rod 140, so that the pedal connecting rod 140 has sufficient support on the pedal part 230, avoiding the pedal part 230 from being overturned or broken, and ensuring the support effect of the pedal part 230. In addition, the length d of the pedal part 230 is greater than or equal to 0.6H of the length of the pedal connecting rod 140, so that the pedal part 230 has sufficient area to contact the user's feet, enabling the user to conveniently step on and off through the pedal part 230, thereby improving the user experience and having a better technical effect.

[0062] In the related art, a locking part is used to lock the boarding pedal in the unfolded position and the recovered position to ensure that the boarding pedal is in a stable state. The present inventor found in research that the locking part can only lock the first movable part 150 in a certain direction, but the locking part cannot completely lock the first movable part 150 in a locked state, thus causing the pedal of the pedal device 200 to shake or swing.
