Description

Technical Field

[0001] The utility model relates to the technical field of automobile pedals, and more particularly to a large-span electric pedal mechanism used on automobiles. Background Art

[0002] The electric pedal is a kind of automatically retractable pedal. When the door is opened, the electric pedal automatically extends and stops when it reaches the limit position. When the door is closed, the electric pedal automatically retracts and retracts to the bottom of the car, giving a feeling of ceremonial welcoming. The electric pedal provides convenient service for getting on and off high-chassis cars, especially for female friends, children or older people. It directly provides practical and comfortable functions. Compared with fixed pedals, it will not reduce the passability of the car.

[0003] A self-retractable electric trunk step for automobiles with publication number CN116605145A is designed. By setting two protrusions on the active arm and corresponding buffer blocks on the auxiliary arm, the buffer blocks respectively abut against the two protrusions when the electric step is folded or unfolded. This not only improves the overall supporting capacity of the telescopic mechanism, but also avoids direct contact between the active arm and the auxiliary arm, avoiding wear between the active arm and the auxiliary arm, thereby extending the service life of the electric step.

[0004] However, due to the limitations of the transmission structure, the upper end surface of the electric pedal cannot be flattened after the pedal is opened, and can only be tilted inward at a certain angle. This setting will, to a certain extent, affect the experience of people inside the car getting off or people outside the car getting on. Utility Model Content

[0044] The telescopic mechanism in the electric pedal is particularly important. It not only needs to have a good transmission system and be smooth when opening or closing the pedal, but also be convenient for people to step on. For this purpose, this application proposes an electric pedal mechanism with a large span.

[0045] The following embodiments will be used to describe in detail a large-span electric pedal mechanism of the present application.

[0046] Example 1:

[0047] like Figure 1-Figure 7 As shown, in this embodiment, a large-span electric pedal mechanism includes: a pedal 100, which is in the shape of a triangular prism and can bear a large load, so that people getting on and off the vehicle can step on it smoothly; and a telescopic component 200, which is used to drive the pedal 100 to open and close.

[0048] The telescopic assembly 200 includes: a mounting base 210, which is disposed on the vehicle body; a transmission arm 220, one end of which is connected to the pedal 100; a driven arm 230, which has two rotation points and is divided into O1 and O2 distributed vertically, with a distance L1 between O1 and O2, O1 is rotatably connected to the mounting base 210, and O2 is rotatably connected to the transmission arm 220; an active arm 240, which has two rotation points and is divided into O3 and O4 distributed vertically, with a distance L2 between O3 and O4, O3 is rotatably connected to the mounting base 210, and O4 is rotatably connected to the transmission arm 220; and a driving unit 250 for driving O3 on the active arm 240 to rotate, thereby driving the pedal 100 to open outward from the vehicle body or close inward.

[0049] Among them, L1>L2, when the pedal 100 is opened outward, the active arm 240 and the driven arm 230 drive the transmission arm 220 to perform a curved motion, so that the pedal 100 moves from an upward inclined state to a flat state.

[0050] The telescopic assembly 200 is generally composed of four mutually hinged transmission arms 220. By driving one of the transmission arms 220 to rotate, the transmission arms 220 connected thereto are driven to move, thereby achieving a telescopic effect.

[0051] This is also the case in this embodiment, where the driving unit 250 drives the active arm 240 to rotate, causing the passive arm 230 to rotate and the transmission arm 220 to move in a curve, thereby opening or closing the pedal 100 located on the transmission arm 220. To ensure that the pedal 100 appears flat when opened, the lengths of the active and passive arms 240, 230, and their rotation points are precisely adjusted.

[0052] Specifically, the distance between O1 and O2 is L1, the distance between O3 and O4 is L2, where L1>L2; the distance between O1 and O3 is L3, the distance between O2 and O4 is L4; where L3>L 4； The upper end surface of the mounting base 210 is used as a reference plane; wherein, the height of O1 from the reference plane is H1, the height of O2 from the reference plane is H2, the height of O3 from the reference plane is H3, and the height of O4 from the reference plane is H4; H1<H3; H2>H4.

[0053] In this embodiment of the large-span electric step mechanism, the core of the design lies in utilizing the principle of the connecting rod mechanism (four-bar linkage mechanism) and carefully calculating the size and position of each component to ensure that the step 100 can be smoothly and effectively opened outward from the vehicle body or closed inward. At the same time, when opened, it can reach a nearly horizontal position to provide a stable tread for passengers to get on and off the vehicle.

[0054] In this embodiment, it is optimized that the upper end surface of the pedal 100 has anti-slip stripes 130 arranged in the horizontal direction.

[0055] By providing anti-slip stripes 130 to increase the roughness of the pedal 100 surface, the friction between the passenger's sole and the contact surface of the pedal 100 is effectively improved. Even in rainy and snowy weather or when the soles of the feet are slippery, the stability of the passengers when getting on and off the vehicle can be ensured, greatly reducing the risk of slipping.

[0056] In this embodiment, it should be noted that a slide groove 221 is provided on the transmission arm 220, and a slider 110 adapted to the slide groove 221 is provided on the pedal 100. The transmission arm 220 slides in the slide groove 221 on the transmission arm 220 via the slider 110 thereon. A locking member 120 is further provided between the transmission arm 220 and the pedal 100 for locking the two.

[0057] The sliding groove 221 on the transmission arm 220 is arranged in the horizontal direction, so that the position of the pedal 100 can be adjusted in the horizontal direction.

[0058] In order to improve the flexibility and functionality of the pedal 100, this embodiment adopts a sliding locking structure, in which a slide groove 221 is provided on the transmission arm 220, and the pedal 100 is equipped with a slider 110 adapted thereto. This design allows the pedal 100 to slide horizontally on the transmission arm 220, so that the position of the pedal 100 can be adjusted according to actual needs, such as adjusting the extended length of the pedal 100 to adapt to different boarding and alighting requirements or vehicle body structures.

[0059] In this embodiment, it should be noted that there are two sets of telescopic assemblies 200 , which are symmetrically arranged on the vehicle body, and the two ends of the pedal 100 are respectively arranged on the two sets of telescopic assemblies 200 .

[0060] The two sets of telescopic components 200 are used to drive the pedal 100 with a large span to be telescopic.

[0061] Example 2:

[0062] This embodiment is a further improvement based on the first embodiment.

[0063] In this embodiment, if Figure 8 As shown, a large-span electric pedal mechanism, the telescopic component also includes: a radar module 260, which is arranged on the pedal 100 and is used to detect obstacles around the pedal 100; and a control system 270, which controls the operating status of the driving unit 250 through the signal detected by the radar module 260.

[0064] The anti-collision function of the electric step, also known as the obstacle avoidance function, mainly utilizes sensors to detect obstacles, thereby controlling the drive unit to make corresponding states through the control system to achieve obstacle avoidance. For example, when the sensor detects an obstacle around the step, the step will automatically stop moving to avoid hitting the obstacle. However, this technology can only detect obstacles when the step is in motion, which is relatively passive. For this reason, this embodiment is equipped with a radar module 260 and a control system 270. The radar module 260 and the control system 270 can sense obstacles encountered by the step 100 when it is opened or closed in advance, thereby issuing a warning in advance and taking action.

[0065] Through these optimized designs, the pedal 100 is not only enhanced in terms of safety, but also improved in terms of operational convenience and comfort, bringing users a smoother and more secure use experience.

[0066] While various embodiments of the present disclosure have been described above, the above descriptions are illustrative, non-exhaustive, and not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to existing technologies, or to enable others skilled in the art to understand the embodiments disclosed herein.
