DETAILED DESCRIPTION

[0035] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0036] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0037] The following combination Figures 1-8 A pedal connection structure 1 , a pedal device 100 having the pedal connection structure 1 , and a vehicle having the pedal device 100 according to an embodiment of the present invention will be described in detail.

[0038] Reference Figure 1-Figure 2 As shown, a pedal connection structure 1 according to an embodiment of the present invention includes: a bracket 10, a swing mechanism 20, and a first buffer 30. The bracket 10 is connected to the vehicle body; the swing mechanism 20 is connected to the bracket 10, and the swing mechanism 20 is connected to the pedal 2; the first buffer 30 is fixed to the bracket 10 and is used to buffer the impact force of the swing mechanism 20 on the bracket 10.

[0039] Specifically, the first buffer member 30 is fixed to the bracket 10 via a fixing member. Optionally, a limiting rib is provided on the bracket 10 so that the first buffer member 30 can be more accurately mounted on the bracket 10.

[0040] The step device 100 is typically stored within the vehicle's chassis, skirt, or other vehicle body locations, without affecting the vehicle's minimum ground clearance or appearance. This improves the convenience of getting on and off the vehicle (particularly on high-floor vehicles). In related art, the step 2 of the step device 100 lacks a buffer during movement between its stowed and deployed positions, resulting in uneven movement of the step connection structure 1 connecting the step 2 to the vehicle body. The significant changes in inertial velocity and acceleration during movement of the step device 100 can cause jitter, jerking, and unusual noises during the deployment of the step 2, degrading the user's driving experience.

[0041] According to the pedal connection structure 1 of the embodiment of the present invention, by adding a first buffer member 30 to the bracket 10, during the deployment of the pedal 2, the first buffer member 30 fixed to the bracket 10 and the swing mechanism 20 contact and squeeze each other, thereby buffering the impact force of the swing mechanism 20 on the bracket 10 during movement, thereby ensuring smooth deployment of the pedal 2. The provision of the first buffer member 30 can suppress the problem of a sudden increase in speed of the pedal 2 during movement from the stowed position to the deployed position, reduce the mechanical impact between the swing mechanism 20 and the bracket 10, avoid mechanical abnormal noise during the deployment of the pedal 2, increase the shock absorption and buffering effect of the pedal 2, make the pedal 2 move more smoothly at the end of deployment, improve the sound quality, improve the NVH performance of the vehicle, increase the service life and stability of the pedal device 100, and increase the luxury and comfort of the pedal device 100, thereby enhancing the user's driving experience.

[0042] In some embodiments of the present invention, the swing mechanism 20 includes: a first swing member 21, a second swing member 22 and a connecting seat 23, the connecting seat 23 is used to fix the pedal 2, the first end of the first swing member 21 and the first end of the second swing member 22 are both rotatably connected to the bracket 10, the second end of the first swing member 21 is rotatably connected to the end of the connecting seat 23 away from the pedal 2, and the second end of the second swing member 22 is rotatably connected to the end of the connecting seat 23 close to the pedal 2.

[0043] Combine Figure 1-Figure 7 As shown, Figure 3 is a schematic diagram of the pedal device 100 in the deployed position; Figure 4 yes Figure 3 Cross-sectional view at AA in the middle; Figure 5 is a stowed schematic diagram of the pedal device 100 in the stowed position; Figure 6 yes Figure 5 Cross-sectional view at the middle BB.

[0044] As the pedal 2 moves from the stowed position to the deployed position, the first buffer member 30 fixed to the bracket 10 and the second swinging member 22 of the swing mechanism 20 contact and compress each other. When the pedal 2 is in the deployed position, the first buffer member 30 is sandwiched between the second swinging member 22 and the bracket 10. As the pedal 2 deploys, when the controller issues a deceleration command, the upper end surface of the second swinging member 22 instantly contacts the end of the first buffer member 30 and begins to continuously compress the first buffer member 30, causing the second swinging member 22 to experience a downward reaction force opposite to its original direction of motion, thereby slowing the upward and outward movement of the second swinging member 22. The amount of interference between the second swinging member 22 and the first buffer member 30 continuously increases, causing the reaction force provided by the first buffer member 30 to continuously increase. By adjusting the amount of interference between the first and second swinging members 30 and 22 at different stages of motion, the first buffer member 30 experiences different reaction forces, thereby suppressing the gradual increase in speed due to inertia. This allows the controller (e.g., a domain controller) to more linearly control the motion of the pedal 2, allowing the pedal 2 to deploy in a relatively stable manner.

[0045] By setting the first buffer member 30, the problem of a sudden increase in speed of the pedal 2 during the movement from the stowed position to the deployed position can be suppressed, the mechanical impact between the second swing member 22 and the bracket 10 can be reduced, and mechanical abnormal noise of the pedal 2 during the deployment process can be avoided, so that the pedal 2 can move more smoothly at the end of deployment, the sound quality is improved, the NVH performance of the vehicle is improved, and the adjustment difficulty of the control software (such as domain control software) is reduced, so that the pedal device 100 can meet the movement requirements under different layout conditions and different human-machine requirements, while increasing the service life and use stability of the pedal device 100, increasing the luxury and comfort of the pedal device 100, and improving the user's car experience.

[0046] The operating principle of the pedal connection structure 1 from the stowed state to the deployed state is as follows: the pedal connection structure 1 and the pedal 2 are normally in the stowed state. When the user opens the vehicle door, the first swinging member 21 drives the second swinging member 22 to move, thereby causing the connecting seat 23, which is simultaneously rotatably connected to the first swinging member 21 and the second swinging member 22, to move upward and outward. The connecting seat 23 can drive the pedal 2 fixed thereto to move upward and outward. As the pedal 2 deploys, the interference between the second swinging member 22 and the first buffer member 30 continuously increases, allowing the pedal 2 to deploy smoothly to its final position in the upward and outward direction, allowing the user to conveniently enter the vehicle by stepping on the pedal 2. The upward and outward movement refers to the movement of the pedal 2 from its initial position stored in the vehicle body to its final deployed position for the user to step on. Optionally, the user opening the vehicle door includes opening the door when getting on the vehicle and / or opening the door when getting off the vehicle.

[0047] The operating principle of the pedal connection structure 1 from the deployed state to the stowed state is as follows: when the user closes the vehicle door, the first swinging member 21 drives the second swinging member 22 in the opposite direction, thereby causing the connecting seat 23, which is simultaneously rotationally connected to the first and second swinging members 21 and 22, to move downward and inward. The connecting seat 23 then drives the pedal 2 fixed to it to move downward and inward. The interference between the second swinging member 22 and the first buffer member 30 continuously decreases, causing the pedal 2 to return to its initial position of the stowed state, at which point the pedal 2 is fully retracted to the bottom of the vehicle body. Due to the provision of the first buffer member 30, when the pedal 2 is in the final deployed position, a portion of the force exerted on the pedal 2 is used to compress the first buffer member 30. The downward and inward movement refers to the movement of the pedal 2 from its final deployed position, where it is stepped on by the user, to its initial position retracted within the vehicle body. Optionally, the user closing the vehicle door includes closing the door upon getting on the vehicle and / or closing the door upon getting off the vehicle.

[0048] In some embodiments of the present invention, the bracket 10, the first swinging member 21, the second swinging member 22, and the connecting seat 23 together form a four-bar linkage structure, so that the connecting seat 23 drives the pedal 2 to move between the stowed position and the deployed position. The first swinging member 21 and the second swinging member 22 are connected to the connecting seat 23 at different positions, and the second swinging member 22 is located on the side closer to the pedal 2 relative to the first swinging member 21, so that the bracket 10, the first swinging member 21, the second swinging member 22, and the connecting seat 23 together form a four-bar linkage structure, with the first swinging member 21 as the active rod and the second swinging member 22 as the driven rod. The rotation of the first swinging member 21 drives the rotation of the second swinging member 22 and the movement of the connecting seat 23, so that the connecting seat 23 drives the pedal 2 to move between the stowed position and the deployed position.

[0049] In actual implementation, taking the pedal device 100 installed under the side door of the vehicle body as an example, the rotation axis of the first swing member 21 and the second swing member 22 extends along the front and rear directions of the vehicle body, and the first swing member 21 and the second swing member 22 are simultaneously connected to the connecting seat 23. By rotating the first swing member 21 and the second swing member 22, the pedal 2 can produce a certain displacement in the left and right directions of the vehicle body while undergoing relative rotation, that is, the connecting seat 23 drives the pedal 2 to move between the retracted position and the deployed position.

[0050] In some embodiments of the present invention, the swing mechanism 20 is movable between a first position and a second position. When the swing mechanism 20 is in the first position, the first buffer member 30 is in an extended state. When the swing mechanism 20 is in the second position, the first buffer member 30 is in a compressed state under the action of the second swing member 22. When the swing mechanism 20 is in the first position, the second swing member 22 of the swing mechanism 20 does not squeeze the first buffer member 30, and the first buffer member 30 is in an extended state. At this time, the first buffer member 30 does not generate a reaction force. When the swing mechanism 20 is in the second position, the first buffer member 30 fixed to the bracket 10 and the second swing member 22 of the swing mechanism 20 squeeze each other. The first buffer member 30 is in a compressed state under the action of the second swing member 22, and the first buffer member 30 provides a counteracting force to the second swing member 22.

[0051] In some embodiments of the present invention, when the swing mechanism 20 moves to a preset position between the first and second positions, the first buffer 30 contacts the second swing member 22 and is in an extended state. Before the swing mechanism 20 moves from the first position to the preset position, a gap exists between the second swing member 22 and the first buffer 30. When the swing mechanism 20 moves to the preset position, the first buffer 30 and the second swing member 22 are in a critical state, contacting each other but without any mutual force. After the swing mechanism 20 moves to the preset position, the second swing member 22 and the first buffer 30 interfere with each other. As a result, the pedal 2 can move from the stowed position to the deployed position in a relatively stable manner.

[0052] In some embodiments of the present invention, reference Figure 7 and Figure 8 As shown, the angle θ between the compression direction of the first buffer 30 and the movement direction of the second swing member 22 is less than a preset angle; wherein the movement direction is the normal direction of the second swing member 22 moving from the first position to the second position. Optionally, the numerical range of the preset angle is 30° to 45°, such as 30°, 35°, 40°, and 45°. Figure 8As shown, when the swing mechanism 20 moves to the preset position, the first buffer member 30 and the second swing member 22 are tangent to each other, and the normal direction perpendicular to the tangent surface between the two is the compression direction of the first buffer member 30.

[0053] In some embodiments of the present invention, the portion of the first buffer member 30 facing the second swing member 22 is provided with a raised portion 31. During the movement of the pedal 2, unless there is external interference, the pedal 2's speed will increase under the action of gravity. Due to the kinematic characteristics of the four-bar linkage (kinematic characteristics can be analyzed using motion analysis software to generate a velocity-time curve at the end of the pedal 2), when the pedal 2 is positioned with a small difference between the stowed and deployed positions, its speed will surge as it approaches the final deployed position. At the moment the vehicle control slow-stop program intervenes, i.e., the moment of speed surge, the second swing member 22 and the first buffer member 30 become tangent. Therefore, the raised portion 31 should be provided on the end of the first buffer member 30 opposite the second swing member 22. This raised portion 31 can have a large rounded corner. Furthermore, to ensure that the force exerted by the second swing member 22 compressing the first buffer member 30 is uniform and increases with increasing speed, the raised portion 31 can be designed in the shape of an inverted triangle. The amount of interference between the second swing member 22 and the first buffer member 30 increases linearly with the movement, but the amount of interference between the two increases in linear proportion to the speed of the pedal 2. Optionally, the Shore hardness of the first buffer member 30 can also be adjusted according to the speed of the pedal 2 and the interference between the second swing member 22 and the first buffer member 30 , and the two are in an inversely proportional relationship.

[0054] In some embodiments of the present invention, the first buffer member 30 is made of a flexible material that can generate a force with the second swing member 22. Optionally, the first buffer member 30 is made of at least one of rubber, PP-E, TPE, and TPV.

[0055] In some embodiments of the present invention, a mounting flange 24 is provided on the pedal 2, and an escape space 231 is provided on the connecting seat 23. The mounting flange 24 and the escape space 231 cooperate with each other and are fixedly connected.

[0056] In some embodiments of the present invention, reference Figure 1 and Figure 2As shown, the pedal connection structure 1 also includes: a driving device 40, which is installed on the bracket 10 and is transmission-connected to the first swinging member 21. The driving device 40 provides power for the movement of the swinging mechanism 20, so as to drive the pedal 2 to move between the deployed position and the stowed position. Specifically, the driving assembly 40 is transmission-connected to the first swinging member 21. When the driving assembly 40 is actuated, the first swinging member 21 is driven to move accordingly, and the second swinging member 22 connected to the first swinging member 21 is driven to move. The connecting seat 23 connected to the first swinging member 21 and the second swinging member 22 drives the fixedly connected pedal 2 to flip, thereby achieving the movement of the pedal 2 between the deployed position and the stowed position. As a result, the driving assembly 40 drives the swinging mechanism 20 to move, providing power to the swinging mechanism 20 to cause the pedal 2 to flip.

[0057] In some embodiments of the present invention, the drive device 40 includes an output shaft 41, and the output shaft 41 of the drive device 40 is fixedly connected to the first end of the first swinging member 21. Thus, the drive device 40 can drive the first swinging member 21 to move by rotating the output shaft 41, and then drive the four-bar linkage structure to move, so that the pedal 2 moves between the stowed position and the deployed position. Optionally, in some embodiments, the drive device 40 includes a drive motor and a transmission gear. The transmission output shaft of the transmission gear serves as the output shaft 41 of the drive device 40. In other embodiments, the drive device 40 can also be a drive motor. The motor shaft of the drive motor serves as the output shaft 41 of the drive device 40. In addition, the drive device 40 can also be a drive device of other structures, which is not further limited here.

[0058] Specifically, when the user opens the car door, the drive motor starts to rotate, driving the first swinging member 21 to rotate along the output shaft 41, and the first swinging member 21 drives the second swinging member 22 to rotate clockwise, thereby causing the connecting seat 23 that is simultaneously connected to the first swinging member 21 and the second swinging member 22 to rotate upward and outward. As the pedal 2 is unfolded, the interference between the second swinging member 22 and the first buffer member 30 continues to increase, so that the pedal 2 is unfolded to the end state position in the upper and outer directions in a stable posture, and the user can conveniently enter the car by stepping on the pedal 2.

[0059] When the user closes the car door, the drive motor starts to rotate in the opposite direction, driving the first swinging member 21 to rotate along the output shaft 41. The first swinging member 21 drives the second swinging member 22 to rotate counterclockwise, thereby causing the connecting seat 23 connected to the first swinging member 21 and the second swinging member 22 to rotate simultaneously to move downward and inward. The connecting seat 23 can drive the pedal 2 fixedly connected to it to move downward and inward. The interference between the second swinging member 22 and the first buffer member 30 continues to decrease, causing the pedal 2 to return to its initial position in the retracted state. At this time, the pedal 2 is completely retracted to the bottom of the vehicle body.

[0060] Therefore, through the setting of the first buffer member 30, not only the mechanical impact between the second swinging member 22 and the bracket 10 can be reduced, but also the mechanical impact between the motor shaft of the drive motor, the transmission gear structure and other motion structures can be reduced, thereby avoiding mechanical abnormal noise of the pedal 2 during the deployment process. At the same time, the gear speed difference of the transmission gear structure can be reduced, so that the pedal 2 can move more smoothly at the end of deployment, the sound quality is improved, the NVH performance of the vehicle is improved, and the difficulty of adjusting the control software is reduced, so that the pedal device 100 can meet the movement requirements under different layout conditions and different human-machine requirements, increase the service life and use stability of the pedal device 100, and at the same time increase the luxury and comfort of the pedal device 100, thereby improving the user's car experience.

[0061] In some embodiments of the present invention, the output shaft 41 of the drive device 40 is secured to the first swinging member 21 using a concave-convex structure, and / or the output shaft 41 of the drive device 40 is secured to the first swinging member 21 via fasteners. Alternatively, in some embodiments, the output shaft 41 of the drive device 40 is secured to the first swinging member 21 solely via a concave-convex structure. For example, a groove may be provided on the output shaft 41, and a protrusion may be provided on the first swinging member 21, where the groove on the output shaft 41 cooperates with the protrusion on the first swinging member 21 to secure the two. Alternatively, a protrusion may be provided on the output shaft 41, and a groove may be provided on the first swinging member 21, where the protrusion on the output shaft 41 cooperates with the groove on the first swinging member 21 to secure the two. Alternatively, both a protrusion and a groove may be provided on the output shaft 41, and the first swinging member 21 may be provided with a groove and a protrusion that match the output shaft 21, thereby achieving a concave-convex securement of the output shaft 41 to the first swinging member 21. In other embodiments, the output shaft 41 of the drive device 40 is secured to the first swinging member 21 solely via fasteners. In some other embodiments, the output shaft 41 of the driving device 40 and the first swinging member 21 are fixed with a concave-convex structure, and the output shaft 41 and the first swinging member 21 are fixed with fasteners, thereby achieving a tighter fixed connection.

[0062] In some embodiments of the present invention, reference Figure 1 As shown, the swing mechanism 20 further includes a first rotating shaft 211, which passes through the bracket 10 and the first end of the first swinging member 21. The first swinging member 21 is in transmission connection with the bracket 10 via the first rotating shaft 211. Specifically, the first rotating shaft 211 is used to connect the bracket 10 and the first swinging member 21. The first rotating shaft 211 passes through the bracket 10 and the first swinging member 21 to connect the bracket 10 and the first swinging member 21. The first rotating shaft 211 can drive the first swinging member 21 to rotate.

[0063] In some embodiments of the present invention, the swing mechanism 20 further includes a first bearing having an inner ring and an outer ring. The inner ring is rotatable relative to the outer ring. The outer ring is fixed to the bracket 10, and the inner ring is sleeved on the first rotating shaft 211. Specifically, a first bearing is disposed between the first rotating shaft 211 and the bracket 10. The first bearing includes an inner ring and an outer ring. The outer ring of the first bearing is in an interference fit with the bracket 10, while the inner ring of the first bearing is in a clearance fit with the first rotating shaft 211. Therefore, the first rotating shaft 211 can rotate in the first bearing, thereby enabling the first rotating shaft 211 to drive the first swing member 21 to rotate relative to the bracket 10.

[0064] In some embodiments of the present invention, the swing mechanism 20 further includes a second rotating shaft 221, which passes through the bracket 10 and the first end of the second swing member 22. The second swing member 22 is in transmission connection with the bracket 10 via the second rotating shaft 221. Specifically, the second rotating shaft 221 is used to connect the bracket 10 and the second swing member 22. The second rotating shaft 221 passes through the bracket 10 and the second swing member 22 to connect the bracket 10 and the second swing member 22. The second rotating shaft 221 can drive the second swing member 22 to rotate.

[0065] In some embodiments of the present invention, the swing mechanism 20 further includes a second bearing having an inner ring and an outer ring. The inner ring is rotatable relative to the outer ring. The outer ring is fixed to the bracket 10, and the inner ring is sleeved on the second rotating shaft 221. The outer ring of the second bearing is in an interference fit with the bracket 10, while the inner ring of the second bearing is in a clearance fit with the second rotating shaft 221. Therefore, the second rotating shaft 221 can rotate within the second bearing, thereby enabling the second rotating shaft 221 to drive the second swing member 22 to rotate relative to the bracket 10.

[0066] In some embodiments of the present invention, the swing mechanism 20 further comprises a third rotating shaft 212, which passes through the first swing member 21 and the end of the connecting seat 23 away from the pedal 2. The first swing member 21 is in transmission connection with the connecting seat 23 via the third rotating shaft 212. Specifically, the third rotating shaft 212 is used to connect the first swing member 21 and the connecting seat 23. The third rotating shaft 212 passes through the first swing member 21 and the connecting seat 23, connecting the first swing member 21 and the connecting seat 23 away from the pedal 2. The first rotating shaft 211 can drive the first swing member 21 to rotate, and the first swing member 21 drives the end of the connecting seat 23 away from the pedal 2 to rotate via the third rotating shaft 212. Since the connecting seat 23 is fixedly connected to the pedal 2, the pedal 2 rotates and expands or retracts as the connecting seat 23 rotates.

[0067] In some embodiments of the present invention, the swing mechanism 20 further includes a third bearing having an inner ring and an outer ring, the inner ring being rotatable relative to the outer ring. The outer ring is fixed to the connecting seat 23, and the inner ring is sleeved on the third rotating shaft 212. The outer ring of the third bearing is in an interference fit with the connecting seat 23, while the inner ring of the third bearing is in a clearance fit with the third rotating shaft 212. Therefore, the third rotating shaft 212 can rotate within the third bearing, thereby enabling the first swing member 21 to drive the connecting seat 23 to rotate away from the end of the pedal 2 via the third rotating shaft 212.

[0068] In some embodiments of the present invention, the swing mechanism 20 further includes a fourth rotating shaft 222. The fourth rotating shaft 222 extends through the second swinging member 22 and the connecting seat 23 at an end near the pedal 2. The second swinging member 22 is in transmission connection with the connecting seat 23 via the fourth rotating shaft 222. Specifically, the fourth rotating shaft 222 is used to connect the second swinging member 22 and the connecting seat 23. The fourth rotating shaft 222 passes through the second swinging member 22 and the connecting seat 23, connecting the second swinging member 22 and the connecting seat 23 at an end near the pedal 2. The fourth rotating shaft 222 can drive the second swinging member 22 to rotate. The second swinging member 22 drives the connecting seat 23 at an end near the pedal 2 to rotate via the fourth rotating shaft 222. Because the connecting seat 23 is fixedly connected to the pedal 2, the pedal 2 rotates and expands or retracts as the connecting seat 23 rotates.

[0069] In some embodiments of the present invention, the swing mechanism 20 further includes a fourth bearing having an inner ring and an outer ring, the inner ring being rotatable relative to the outer ring. The outer ring is fixed to the connecting seat 23, and the inner ring is sleeved on the fourth rotating shaft 222. The outer ring of the fourth bearing is in an interference fit with the connecting seat 23, while the inner ring of the fourth bearing is in a clearance fit with the fourth rotating shaft 222. Therefore, the fourth rotating shaft 222 can rotate within the fourth bearing, thereby enabling the second swing member 22 to drive the connecting seat 23 to rotate at the end closest to the pedal 2 via the fourth rotating shaft 222.

[0070] In some embodiments of the present invention, the connecting base 23 is provided with an opening 232, and the third rotating shaft 221 and the fourth rotating shaft 222 are both arranged across the opening 232. Both ends of the third rotating shaft 221 and the fourth rotating shaft 222 are respectively fixedly disposed in corresponding shaft holes provided on the two arms of the opening 232.

[0071] In some embodiments of the present invention, the swing mechanism 20 further includes a second buffer member, which is fixed to the first swing member 21 and / or the second swing member 22, so that when the pedal 2 is in the retracted position, the second buffer member is sandwiched between the first swing member 21 and the second swing member 22. Specifically, the second buffer member can be provided only on the first swing member 21, only on the second swing member 22, or on both the first swing member 21 and the second swing member 22. By fixing the second buffer member between the first swing member 21 and the second swing member 22, the impact force between the first swing member 21 and the second swing member 22 can be buffered. When the pedal 2 is in the retracted position, the second buffer member contacts and presses against the first swing member 21 and / or the second swing member 22, thereby preventing friction between the first swing member 21 and the second swing member 22.

[0072] In some embodiments of the present invention, the swing mechanism 20 further includes a third buffer member fixed to the connecting seat 23 such that, when the pedal 2 is in the deployed position, the third buffer member is sandwiched between the second swing member 22 and the connecting seat 23. By fixing the third buffer member between the second swing member 22 and the connecting seat 23, the impact force of the second swing member 22 on the connecting seat 23 can be cushioned. When the pedal 2 is in the deployed position, the third buffer member fixed to the connecting seat 23 contacts and squeezes the second swing member 22, preventing friction between the second swing member 22 and the connecting seat 23.
