Description

Technical Field

[0001] This invention relates to the field of automotive parts, specifically to a dual-motor coordinated electric pedal area expansion mechanism. Background Technology

[0002] With the rapid development of the automotive industry and the continuous improvement of consumption levels, users' requirements for vehicle driving experience have gradually shifted from basic transportation functions to a comprehensive pursuit of comfort, safety, and convenience. Under this trend, electric car pedals, as an important feature to improve the convenience of getting in and out of the vehicle, can automatically extend when the door is opened and automatically retract when it is closed, providing stable and suitable foot support for passengers and effectively reducing the step height when getting in and out of the vehicle.

[0003] Currently, most common electric car pedals use a four-bar linkage to achieve pedal extension and retraction. The pedal panel is usually integrated into the driven arm of the four-bar linkage to achieve a coordinated operation of extending the pedal when the door is opened and retracting it when the door is closed. Due to the compactness of the overall structure and the constraints of vehicle chassis space, the width of the pedal panel of this four-bar electric pedal is generally limited to between 110mm and 130mm and cannot be further expanded. In actual use, especially in rainy or snowy weather, poor lighting, or when passengers move quickly, this narrow panel can easily lead to unstable foot pressure, missed steps, or uneven force distribution, thus affecting the stability and safety of passengers getting in and out of the vehicle.

[0004] Therefore, a dual-motor cooperative automotive electric pedal area expansion mechanism is proposed to solve the problem that the pedal panel is too narrow to be expanded. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dual-motor coordinated electric pedal area expansion mechanism for automobiles, which solves the problem that the pedal panel is too narrow to be expanded.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dual-motor cooperative electric pedal area expansion mechanism for automobiles, including a pedal that can move from a first position to a second position along a first direction, a stepping area formed on the pedal, an extension plate that moves along the first direction is provided inside the pedal, and the extension plate can move from the second position to a third position, and the area of ​​the stepping area increases as the extension plate moves in the first direction.

[0007] Preferably, the extension plate is provided with a crank structure, and the extension plate is connected to a first motor through the crank mechanism. The operation of the first motor causes the extension plate to switch between a second position and a third position.

[0008] Preferably, the crank structure includes crank arm a and crank arm b, which are connected by a hinge shaft. The end of crank arm a away from crank arm b is connected to the output end of the motor. A connecting seat is provided on the extension plate, and the end of crank arm b away from crank arm a is connected by the hinge shaft connecting seat.

[0009] Preferably, the pedal is provided with a push structure, and the pedal is connected to a second motor through the push structure. The operation of the second motor causes the pedal to switch between a first position and a second position.

[0010] Preferably, the pushing structure includes a mounting base, a connecting arm a, a connecting arm b, and a pushing arm. The pushing arm includes a hinge portion and a pushing portion. The pushing portion is connected to the pedal. Both connecting arms a and b are connected to the hinge portion via hinge shafts. The ends of connecting arms a and b away from the hinge portion are connected to the mounting base via hinge shafts. The output end of the second motor is connected to connecting arm a.

[0011] Preferably, a guide seat is provided on the pushing part along the first direction, and a third roller is provided on the side of the extension plate away from the pedal, and the third roller is rotatably connected to the guide seat.

[0012] Preferably, the extension plate has a receiving groove on the side away from the pedal, the pushing part is disposed in the receiving groove, and the third roller is disposed in the receiving groove.

[0013] Preferably, the third roller is a V-shaped roller, and the side of the guide seat corresponding to the third roller is provided as a contact surface, which is adapted to the outer surface of the third roller.

[0014] Preferably, a second roller is provided on the side of the pedal facing the extension plate via a mounting bracket, and a storage groove is provided on the side of the extension plate facing the pedal corresponding to the position of the second roller. The second roller passes through the storage groove via the mounting bracket and contacts the inner wall of the storage groove.

[0015] Preferably, the storage groove extends along a first direction, and the inner wall of the storage groove is recessed inward corresponding to the second roller, with the second roller rollingly connected to the inner top wall of the recess.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects: This dual-motor coordinated electric pedal area expansion mechanism for automobiles increases the width of the pedal's foot area by incorporating an extension plate movable along a first direction inside the pedal. As the pedal moves from a first position to a second position, the extension plate extends from the second position to a third position. During use, the extension plate extends along a predetermined trajectory, effectively expanding the width of the foot panel within a limited space. This ensures increased foot contact area for passengers getting in and out of the vehicle, improving pedal support and stability. The design smoothly guides the extension plate's movement as the pedal position changes, avoiding interference or obstruction during operation. This ensures continuous, controllable, and smooth extension while maintaining the compactness and integrity of the overall pedal structure. Through the coordinated movement of the extension plate and the pedal, the foot area remains stable during dynamic adjustments, significantly improving foot instability or missteps, and enhancing passenger safety and comfort when getting in and out of the vehicle. Furthermore, this solution can expand the foot area without increasing the volume of the external structure, making the pedals more versatile and meeting the needs of passengers for pedal area in different postures. At the same time, it optimizes the utilization efficiency of the vehicle's interior space and enhances the functionality and ease of operation of the pedals. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figure 1-8 In this embodiment, a dual-motor coordinated electric pedal 1 area expansion mechanism includes a pedal 1 that can move from a first position 5 to a second position 6 along a first direction. A stepping area 8 is formed on the pedal 1. An extension plate 2 that moves along the first direction is provided inside the pedal 1. The extension plate 2 can move from the second position 6 to a third position 7. The width of the stepping area 8 increases as the extension plate 2 moves in the first direction.

[0021] It should be noted that the first direction is the direction of movement of pedal 1 and extension plate 2 along the side of the vehicle. Pedal 1 is an integral support component installed at the bottom of the vehicle, serving as the main structure for bearing the weight of the feet when passengers get on and off the vehicle.

[0022] In Embodiment 1, the pedal 1 serves as the main load-bearing structure, providing a support surface for passengers to get on and off the vehicle. The pedal 1 moves along a first direction from a first position 5 to a second position 6, completing an external position adjustment and providing space for the extension plate 2 to operate. The extension plate 2, located inside the pedal 1, moves along the first direction, extending from the second position 6 back to the first direction to a third position 7. Its movement trajectory is consistent with the direction of the pedal 1, ensuring that the extension plate 2 smoothly slides off the surface of the pedal 1. During the movement, the front end of the extension plate 2 gradually expands the footing area 8, increasing its width. In the above scheme, the entire movement sequence is as follows: the pedal 1 first moves from the first position 5 to the second position 6, and then the extension plate 2 moves along the same direction from the second position 6 to the third position 7, achieving a dynamic increase in the surface area of ​​the pedal 1. During this process, the pedal 1 and the extension plate 2 work together spatially to ensure that the sliding path of the extension plate 2 is unobstructed, making the entire area expansion action continuous, smooth, and controllable.

[0023] The above solution, through the extension plate 2, allows the width of the footrest area 8 to dynamically increase during use, thereby improving the stability and safety of occupants stepping on the pedal. After the pedal 1 moves to the second position 6, it provides ample space for the extension plate 2 to extend, thus expanding the area of ​​the footrest area 8. With the extension plate 2, the area of ​​the footrest area 8 is increased, meaning the width of the footrest panel is increased, providing more adequate foot support when occupants get on and off the vehicle, reducing the risk of misstepping or uneven force distribution. Furthermore, this method maintains the overall compactness of the pedal 1, expanding its area within a limited space, balancing the appearance integrity and ease of use of the pedal 1, enhancing the comfort and safety of getting on and off the vehicle, while avoiding the need for additional modifications to the vehicle structure.

[0024] Traditional footrest panels, especially in rainy, snowy, or poorly lit environments, present safety hazards due to their narrow footrest area when getting on and off vehicles. To address the instability caused by the limited area of ​​existing footrest panels, the above solution incorporates an extension plate 2 that moves along a first direction inside the footrest 1. After the footrest 1 moves to the second position 6, the extension plate 2 extends to the third position 7, effectively expanding the width of the footrest area 8 on the footrest 1. The extension plate 2 extends along a fixed trajectory, ensuring the continuity and stability of the footrest 1's movement. Simultaneously, this solution improves safety and comfort without altering the overall structure of the footrest 1, resolving the insufficient support for occupants in the limited width of traditional footrest panels, and achieving a balance between functionality and structural compactness.

[0025] It should be noted that the extension plate 2 is made of aluminum alloy extrusion molding, which has wear resistance, mud and water resistance and impact resistance.

[0026] Example 2: The basic content is the same as in Example 1, except that: Please see Figure 4In this embodiment, the extension plate 2 is provided with a crank structure 3. The extension plate 2 is connected to the first motor 24 through the crank mechanism. The operation of the first motor 24 causes the extension plate 2 to switch between the second position 6 and the third position 7.

[0027] Furthermore, the crank structure 3 includes a crank arm a31 and a crank arm b32, which are connected by a hinge shaft. The end of the crank arm a31 away from the crank arm b32 is connected to the output end of the motor. A connecting seat 25 is provided on the extension plate 2, and the end of the crank arm b32 away from the crank arm a31 is connected by the hinge shaft connecting seat 25.

[0028] In Embodiment 2, pedal 1 first moves from first position 5 to second position 6 along the first direction, completing a basic position adjustment and providing space for the movement of extension plate 2. Subsequently, the first motor 24 starts and outputs power, driving the crank arm a31 to rotate. Crank arm a31 and crank arm b32 are connected via a hinge shaft, causing crank arm b32 to follow the movement. The end of crank arm b32 away from crank arm a31 is fixed to the connecting seat 25 on extension plate 2 via the hinge shaft. The movement of crank arm b32 is transmitted to extension plate 2 along the first direction, pushing extension plate 2 from second position 6 to third position 7 along the first direction. During this process, extension plate 2 moves along the first direction, increasing the width of the pedal area 8, ensuring that the expansion of the pedal area 8 is smooth, continuous, and controllable.

[0029] The above solution, through the coordinated operation of the crank structure 3 and the first motor 24, ensures precise and smooth extension of the extension plate 2. The rotational motion of the crank arm a31 is converted into the linear motion of the crank arm b32, propelling the extension plate 2 along the first direction, ensuring that the width of the pedal area 8 increases sequentially without deviation or jamming. This solution improves the controllability and repeatability of the extension process of the extension plate 2, making the expansion of the pedal area reliable and extending its service life. Simultaneously, the increased width of the pedal area 1 due to the extension plate 2 enhances the safety and stability of passengers getting on and off the vehicle, while maintaining the compactness and functionality of the pedal structure.

[0030] Traditional sliding structures are prone to uneven movement of the extension plate 2 due to friction, affecting the safety of the foot pedal area 8. Embodiment 2 avoids inaccurate extension and potential deviation of the extension plate 2 by using a crank structure 3 and a first motor 24. After the first motor 24 operates, it drives the crank arm a31 to rotate, and the crank arm b32 subsequently pushes the extension plate 2 to move along the first direction, achieving precise extension and increasing the width of the foot pedal area 8 with continuous and stable movement. This solution improves the controllability and reliability of the extension plate 2's movement through mechanical drive, solving the problems of inaccurate positioning and unstable operation that occur in traditional structures during area expansion.

[0031] It should be noted that the first motor 24 has forward and reverse rotation control functions, and is independently powered. Its housing protection rating reaches IP67, making it suitable for harsh environments under vehicles. The first motor 24 is connected to the vehicle via a fixed bracket, and the crank arm a31 is also hinged within this fixed bracket and connected to the first motor 24.

[0032] Example 3: The basic content is the same as in Example 2, except that: Please see Figure 5 In this embodiment, the pedal 1 is provided with a push structure 4. The pedal 1 is connected to the second motor 11 through the push structure 4. The operation of the second motor 11 causes the pedal 1 to switch between the first position 5 and the second position 6.

[0033] Furthermore, the pushing structure 4 includes a mounting base 41, a connecting arm a42, a connecting arm b43, and a pushing arm 44. The pushing arm 44 includes a hinge portion 441 and a pushing portion 442. The pushing portion 442 is connected to the pedal 1. Both the connecting arm a42 and the connecting arm b43 are connected to the hinge portion 441 via a hinge shaft. The ends of the connecting arm a42 and the connecting arm b43 away from the hinge portion 441 are connected to the mounting base 41 via a hinge shaft. The output end of the second motor 11 is connected to the connecting arm a42.

[0034] In embodiment 3, the pedal 1 is switched between a first position 5 and a second position 6 by pushing the structure 4 and the second motor 11. After the second motor 11 is working, it outputs power to drive the connecting arm a42 to rotate. The connecting arm a42 and the connecting arm b43 are connected to the hinge part 441 of the push arm 44 through a hinge shaft. The push part 442 is fixed to the pedal 1. As the connecting arm a42 rotates, the connecting arm b43 moves accordingly. The push arm 44 drives the pedal 1 to move from the first position 5 to the second position 6 along the first direction, completing the position switch of the pedal 1 and providing space for the extension plate 2 to extend, laying the foundation for increasing the width of the footing area 8 by extending the extension plate 2.

[0035] In the above scheme, by setting a push structure 4 on pedal 1 and connecting it to the second motor 11, the automatic switching of pedal 1 between the first position 5 and the second position 6 is realized, improving the convenience of operation and the level of automation. The push structure 4 forms a reliable motion chain through connecting arm a42, connecting arm b43 and push arm 44, so that pedal 1 moves smoothly in the first direction. At the same time, the controllable switching of pedal 1 position provides sufficient space for the extension plate 2 to extend, so that the crank structure 3 drives the extension plate 2 to extend from the second position 6 to the third position 7 smoothly, thereby ensuring that the dynamic increase of the width of the pedal area 8 is continuous and smooth, and improving the safety and comfort of passengers when getting on and off the vehicle.

[0036] In the method of expanding the width solely by extending the extension plate 2, if the overall position of the pedal 1 is fixed, the extension of the extension plate 2 may be limited, affecting the effective increase of the foot area 8. Through the coordinated work of the pushing structure 4 and the second motor 11, the pedal 1 can automatically switch between the first position 5 and the second position 6, providing extension space for the extension plate 2 and ensuring smooth and precise expansion of the pedal 1 area. At the same time, the mechanical connection of the pushing structure 4 ensures stable and reliable movement of the pedal 1, avoiding deviation or jamming, and achieving comprehensive optimization of increased foot area 8 width, continuous movement, and occupant safety.

[0037] It should be noted that the second motor 11 and the push structure 4 independently control the position switching of the pedal 1, while the first motor 24 drives the crank structure 3 to control the extension plate 2 to extend. The independent control of the two motors ensures that the movement sequence of the pedal 1 and the extension plate 2 is coordinated, avoiding motion interference or conflict, making the extension plate 2 extension and the pedal 1 position switching process continuous and stable, and improving the reliability of the overall mechanism operation.

[0038] It should also be noted that the second motor 11 is a 12V DC permanent magnet geared motor with a worm gear reduction structure and a self-locking function. The mounting base 41, connecting arm a42, connecting arm b43, and push arm 44 are all made of aluminum alloy, and the hinge shaft uses a stainless steel pin and is equipped with a self-lubricating bushing to ensure smooth rotation and durability. Furthermore, the mounting base 41 is fixed to the vehicle, and the self-locking function of the second motor 11 keeps the pedal 1 and the extension plate 2 in the first position 5.

[0039] Furthermore, a guide seat 443 is provided on the pusher 442 along the first direction, and a third roller 444 is provided on the side of the extension plate 2 away from the pedal 1, and the third roller 444 is rotatably connected to the guide seat 443.

[0040] In application, after pedal 1 moves from the first position 5 to the second position 6, when the extension plate 2 extends, it moves from the second position 6 to the third position 7. At this time, the third roller 444 rolls along the guide seat 443, keeping the extension plate 2 stable and without deviation along a predetermined trajectory during the extension process. This ensures that the trajectory of the extension plate 2 is controllable and the movement is smooth and stable during the extension process. The rolling connection between the third roller 444 and the guide seat 443 effectively guides the extension plate 2 to extend in the first direction, keeping it in a straight line during the movement and avoiding deviation or tilting. This improves the smoothness and reliability of the extension plate 2's extension, ensuring that the increase in the width of the footing area 8 during the movement of the extension plate 2 is continuous and smooth. At the same time, the stability of the extension plate 2 during the extension and retraction processes is significantly improved, enhancing the safety and comfort of getting on and off the vehicle.

[0041] In one specific embodiment, the extension plate 2 has a receiving groove 23 on the side away from the pedal 1, the pushing part 442 is disposed in the receiving groove 23, and the third roller 444 is disposed in the receiving groove 23. The third roller 444 is a V-shaped roller, and the guide seat 443 is provided with a contact surface on the side corresponding to the third roller 444, and the contact surface is adapted to the outer surface of the third roller 444.

[0042] It is understood that the receiving groove 23 provides precise spatial constraints for the movement of the pushing part 442 and the third roller 444, ensuring that they maintain a fixed path when the extension plate 2 extends from the second position 6 to the third position 7, preventing movement deviation. The receiving groove 23 neatly houses the pushing part 442 and the third roller 444 inside the extension plate 2, making the structure compact and space-saving in the retracted state of the extension plate 2 (i.e., the second position 6), while maintaining the overall aesthetic shape of the pedal 1. The third roller 444, as a V-shaped roller, is adapted to the contact surface on the guide seat 443, enabling stable guidance during the extension of the extension plate 2, allowing the extension plate 2 to move smoothly along the first direction without tilting or deviating. The contact surface of the guide seat 443 is adapted to the outer surface of the third roller 444, further ensuring the accuracy and smoothness of the extension of the extension plate 2. The overall design not only improves the stability of the extension of the extension plate 2, but also ensures that the increased area of ​​the pedal 1's stepping area 8 results in continuous and reliable movement, while also taking into account structural compactness and space utilization efficiency.

[0043] Furthermore, the third roller 444, which acts as a V-shaped roller, engages with the contact surface on the guide seat 443, possessing properties that resist mud and water and flying stones, allowing it to maintain smooth long-term movement without additional lubrication. The combination of these two components adapts to complex vehicle environments and harsh road conditions, ensuring that the extension plate 2 remains stable and reliable when extending and retracting in rain, snow, mud, or gravel conditions, thus improving the service life and safety of the pedal 1.

[0044] It is important to emphasize that the extension plate 2, crank structure 3, and push structure 4 are all modular mechanisms that can be integrated with existing pedal panels, occupying little space and not interfering with the original structural layout. Modular mechanisms facilitate adaptation to different vehicle models, improve overall vehicle integration efficiency, and facilitate mass production and maintenance. Example 4: The basic content is the same as in Example 1, except that: Please see Figure 6-8 In this embodiment, a first roller 211 is mounted on the side of the pedal 1 facing the extension plate 2 via a mounting bracket 212. A storage groove 21 is formed on the side of the extension plate 2 facing the pedal 1 corresponding to the position of the first roller 211. The first roller 211 passes through the storage groove 21 via the mounting bracket 212 and contacts the inner wall of the storage groove 21. The storage groove 21 extends along a first direction, and the inner wall of the storage groove 21 is recessed inwards corresponding to the first roller 211, allowing the first roller 211 to roll in contact with the inner top wall of the recess.

[0045] It should also be noted that, in this embodiment, the extension plate 2 has a groove 22 on the side facing the pedal 1. A second roller 221 is provided in the groove 22 through a rotating shaft 222. The outer surface of the second roller 221 extends to the outside of the groove 22. The outer surface of the second roller 221 outside the groove 22 contacts the side of the pedal 1 facing the extension plate 2.

[0046] During the movement of the extension plate 2 from the second position 6 to the third position 7, the second roller 221 contacts the pedal 1 to provide rolling support, and the first roller 211 guides the extension plate 2 to move smoothly in the storage groove 21, ensuring that the trajectory of the extension plate 2 is stable and continuous when it extends to the third position 7 in the first direction and is retracted.

[0047] Through the cooperation of the groove 22 with the second roller 221 and the storage groove 21 with the first roller 211, the contact between the extension plate 2 and the pedal 1 during extension and retraction becomes rolling contact, significantly reducing frictional resistance and improving the smoothness and reliability of the extension plate 2's movement. The second roller 221 provides rolling support for the front end of the extension plate 2, and the first roller 211 guides the movement direction of the extension plate 2 along the storage groove 21, ensuring that the extension plate 2 does not deviate or tilt when extended, thus ensuring stable and smooth movement as the width of the foot pedal area 8 increases. In addition, this solution maintains the overall compactness of the pedal 1 and the extension plate 2, while improving the repeatability and service life of the extension plate 2's movement, enhancing the safety and comfort of passengers getting on and off the vehicle. In addition, the second roller 221 supports the front end of the extension plate 2, and the first roller 211 guides the extension plate 2 to move smoothly in the storage groove 21, so that the trajectory of the extension plate 2 is accurate and the action is continuous when it extends or retracts from the second position 6 to the third position 7. This ensures the stability and safety of the action when the width of the stepping area 8 is increased, without increasing the overall structural complexity, thus achieving a balance between functionality and reliability.

[0048] It should be noted that the outer sides of the second roller 221, the first roller 211, and the third roller 444 are all coated with rubber to reduce metal friction. This significantly reduces noise during the extension and retraction of the extension plate 2, improves the smoothness and quietness of the movement, and maintains the precise trajectory of the extension plate 2.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
