Description

Technical Field

[0001] This utility model belongs to the field of automotive pedal technology, and more specifically, it relates to a retractable accelerator pedal structure. Background Technology

[0002] With the continuous development of intelligent driving technology, the requirements for human-machine interaction space in autonomous driving mode have changed significantly. Traditional fixed accelerator pedals still protrude from the bottom of the cockpit when the vehicle enters intelligent driving mode and no driver intervention is required. This not only occupies valuable legroom and restricts the driver's comfortable seating posture adjustment, but also affects the overall simplicity and aesthetics of the cabin. Especially in high-level autonomous driving, the driver's role is gradually diminished, placing higher demands on the openness and flexibility of the cockpit space. Existing pedal structures lack active retraction functions and cannot dynamically adjust their space occupancy according to driving modes, resulting in cramped legroom and a decreased human-machine experience.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a retractable accelerator pedal structure in order to achieve a more practical purpose. Utility Model Content

[0004] In view of the problems mentioned in the background art above, the present invention provides a retractable accelerator pedal structure.

[0005] The technical solution adopted by this utility model is as follows: a retractable accelerator pedal structure, including a base, a limiting arm, and a return spring. The end of the base is rotatably connected to a pedal arm via a shaft, and a storage assembly is provided between the pedal arm and the base. One end of the limiting arm is rotatably connected to the side wall of the base, and the other end is connected to the pedal arm via the storage assembly. One end of the return spring is connected to the limiting arm, and the other end is connected to the bottom of the base, for realizing the return of the pedal arm.

[0006] Furthermore, the limiting arm includes an integrally formed rotating part, connecting part, and sliding part. The rotating part is rotatably connected to the side wall of the base, the connecting part is fixedly connected to one end of the return spring, and the sliding part is slidably connected to the storage assembly.

[0007] Furthermore, the storage assembly includes an adjusting screw, one end of which is provided with a driving member, the driving member being fixedly connected to the pedal arm, and an adjusting block being threadedly connected to the adjusting screw, the adjusting block being slidably connected to the sliding part.

[0008] Furthermore, the adjusting block is provided with a limiting post, and the sliding part is provided with a limiting groove that matches the limiting post.

[0009] Furthermore, the driving component includes a drive motor, and a mounting base is fixed to the bottom of the pedal arm by bolts. The drive motor is mounted on the mounting base, and the output shaft of the drive motor is connected to an adjusting screw.

[0010] Furthermore, the base has a moving groove starting at the adjusting screw.

[0011] The beneficial effects of this utility model are:

[0012] By installing a storage component between the base and the pedal arm, and connecting one end of the limiting arm to the base and the other end to the pedal arm via the storage component, along with a return spring between the limiting arm and the base, an actively controllable storage mechanism is formed. When the vehicle enters intelligent driving mode, the storage component activates, causing the pedal arm to rotate around the pivot at the end of the base and retract. In manual driving mode, the storage component does not activate, and the pedal arm operates normally thanks to the return spring. This structure utilizes a combination of mechanical linkage and elastic reset to achieve automatic deployment and retraction of the accelerator pedal in different driving modes. This satisfies the functional requirements of driving control while effectively freeing up legroom for the driver when not driving, allowing it to be used as a footrest, thus improving the flexibility and comfort of the cabin space.

[0021] Base 1, moving groove 11, pedal arm 2, mounting base 21, drive motor 22, limit arm 3, rotating part 31, connecting part 32, sliding part 33, limit groove 331, return spring 4, adjusting screw 5, adjusting block 51, limit post 52. Detailed Implementation

[0022] like Figures 1-6 As shown, a retractable accelerator pedal structure includes a base 1, a limiting arm 3, and a return spring 4. The base 1 is rotatably connected to a pedal arm 2 via a shaft at one end, and a storage assembly is provided between the pedal arm 2 and the base 1. One end of the limiting arm 3 is rotatably connected to the side wall of the base 1, and the other end is connected to the pedal arm 2 via the storage assembly. One end of the return spring 4 is connected to the limiting arm 3, and the other end is connected to the bottom of the base 1, for realizing the return of the pedal arm 2.

[0023] By adopting the above technical solution, a storage component is set between the base 1 and the pedal arm 2, and one end of the limiting arm 3 is rotatably connected to the base 1, while the other end is linked to the pedal arm 2 through the storage component. A return spring 4 is also set between the limiting arm 3 and the base 1, thus forming an actively controllable storage mechanism. When the vehicle enters intelligent driving mode, the storage component operates, causing the pedal arm 2 to rotate around the pivot at the end of the base 1 and fold back. In manual driving mode, the storage component does not operate, and the pedal arm 2 relies on the return spring 4 to operate normally. This structure utilizes a combination of mechanical linkage and elastic reset to achieve automatic unfolding and retraction of the accelerator pedal in different driving modes. This not only meets the functional requirements of driving control but also effectively frees up the driver's legroom when not driving, improving the flexibility and comfort of the cabin space.

[0024] As a preferred embodiment, the limiting arm 3 includes an integrally formed rotating part 31, connecting part 32, and sliding part 33. The rotating part 31 is rotatably connected to the side wall of the base 1, the connecting part 32 is fixedly connected to one end of the return spring 4, and the sliding part 33 is slidably connected to the storage assembly. The use of an integrally formed rotating part 31, connecting part 32, and sliding part 33 in the limiting arm 3 not only improves the overall rigidity and reliability of the structure and reduces assembly errors and the risk of loose connections, but also ensures clear division of labor among functional areas and a clear force transmission path. The rotating part 31 enables the pivotal connection between the limiting arm 3 and the base 1, ensuring its rotational stability during storage. The connecting part 32 provides a stable fixed fulcrum for the return spring 4, allowing the spring tension to be effectively transmitted to the limiting arm 3 body. This integrated design makes the limiting arm 3 less prone to fatigue fracture when subjected to repeated alternating loads, while ensuring smooth storage and unfolding movements and repeatability, thus improving the durability and responsiveness of the mechanism.

[0025] As a preferred embodiment, the storage assembly includes an adjusting screw 5, one end of which is provided with a driving member. The driving member is fixedly connected to the pedal arm 2. An adjusting block 51 is threadedly connected to the adjusting screw 5, and the adjusting block 51 is slidably connected to the sliding part 33. The storage assembly adopts a threaded engagement structure between the adjusting screw 5 and the adjusting block 51. The adjusting screw 5 is driven to rotate by the driving member, while the adjusting block 51 cannot rotate due to its slidable connection with the sliding part 33, and can only move along the screw axis. When the driving member is activated, the rotational motion of the adjusting screw 5 is converted into the linear reciprocating motion of the adjusting block 51 through the threaded pair. This linear motion is transmitted to the limiting arm 3 through the sliding part 33, thereby driving the pedal arm 2 to rotate to achieve storage or unfolding.

[0026] As a preferred embodiment, the adjusting block 51 is provided with a limiting post 52, and the sliding part 33 is provided with a limiting groove 331 that matches the limiting post 52. The limiting post 52 on the adjusting block 51 and the matching limiting groove 331 on the sliding part 33 constitute a guiding and limiting mechanism; when the driving member drives the adjusting screw 5 to rotate, it achieves... Figures 3 to 4 The changes.

[0027] As a preferred embodiment, the driving component includes a drive motor 22. A mounting base 21 is bolted to the bottom of the pedal arm 2, and the drive motor 22 is mounted on the mounting base 21. The output shaft of the drive motor 22 is connected to the adjusting screw 5. The drive component uses a drive motor 22, and the mounting base 21 is bolted to the bottom of the pedal arm 2. The motor output shaft is directly connected to the adjusting screw 5, forming a compact driving unit. This arrangement integrates the power source into the pedal body structure, allowing it to move together with the pedal arm 2.

[0028] As a preferred embodiment, the base 1 has a moving groove 11 starting at the adjusting screw 5. The moving groove 11 on the base 1 at the adjusting screw 5 provides necessary space for the movement of the adjusting screw 5. Because the adjusting screw 5 will change position with the movement when the pedal is not retracted in its normal pedaling state, the base 1 needs to be designed with a corresponding clearance mechanism to ensure the feasibility of the mechanism.
