Description

Technical Field

[0001] The invention belongs to the technical field of automobile pedals, and in particular relates to an anti-collision tilting electric pedal. Background Art

[0002] Car footrests are installed under vehicle doors for easy entry and exit. From an ergonomic perspective, a footrest height of approximately 15 cm relative to the ground is ideal for optimal access. To ensure vehicle passability, the footrest should be installed at or above the vehicle's minimum ground clearance. Traditional fixed footrests often create a difficult trade-off between vehicle passability and ease of entry and exit.

[0003] U.S. Patent US6830257B2 describes a retractable vehicle foot pedal. The retractable device of the vehicle foot pedal device adopts a four-bar linkage mechanism. When the vehicle door is opened, the foot pedal automatically extends downward from the vehicle chassis near the vehicle body board to facilitate people getting on and off the vehicle; when the vehicle door is closed, the foot pedal automatically retracts upward to its original position, thereby not affecting the vehicle's passability indicators.

[0004] The retractable vehicle footrest disclosed in US Patent No. 6830257B2 uses a single drive motor to drive a four-bar linkage to extend and retract the footrest. Because a single motor drives each four-bar linkage, the footrest is subjected to uneven force, making the two four-bar linkages prone to asynchrony and poor operational reliability. If two motors were used to drive both four-bar linkages simultaneously, the rotation of the two motors and the four-bar linkages could be out of sync, leading to interference and potentially causing malfunction and damage to the vehicle footrest.

[0005] In addition, more and more vehicles are now equipped with anti-collision beams on both sides of the vehicle body to meet off-road needs. The combination of anti-collision beams and pedals is also a problem that needs to be solved urgently. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to provide a tilting electric pedal with anti-collision function, which is used to avoid the problems of poor working reliability, easy interference, lack of matching anti-collision beams, and inability to adapt to off-road environment requirements of previous automobile pedals.

[0007] In order to solve the above technical problems, the present invention discloses a tilting electric step with anti-collision function, which includes an anti-collision beam, which is fixed to the vehicle body through an anti-collision beam mounting bracket;

[0008] The pedal body is located under the anti-collision beam, and the inner ends of the pedal body are respectively fixed with supporting seats, and the supporting seats have a pivotal inclined portion;

[0009] A driven swing arm is pivotally connected to the pivot oblique portion, and the other end of the driven swing arm is pivotally connected to the mounting base;

[0010] An active swing arm is pivotally connected to the mounting base, and the other end of the active swing arm is pivotally connected to the middle section of the driven swing arm through a transmission connecting rod arm;

[0011] a motor that drives one of the active swing arms to rotate;

[0012] Among them, the driven swing arm, the active swing arm, and the transmission connecting rod arm all correspond to the inclination setting of the pivotal oblique part. The active swing arm is driven by the motor to drive the driven swing arm, so that the pedal body is extended obliquely and exposed to the anti-collision beam; or retracted obliquely and stored in the anti-collision beam.

[0013] According to an embodiment of the present invention, the supporting seat further comprises a supporting transverse portion fixed to the lower side of the pedal body by bolts, and the supporting transverse portion extends and connects to the pivoting oblique portion.

[0014] According to one embodiment of the present invention, the mounting base is inclined, the upper side of the mounting base is fixed with a pedal bracket by bolts, the pedal bracket is fixed to the vehicle body, and the motor is mounted on the lower side of the mounting base.

[0015] According to one embodiment of the present invention, the mounting base is further provided with a protective bracket located at the lower side of the motor, and the protective bracket is provided with a fender.

[0016] According to one embodiment of the present invention, the front end of the driven swing arm has a front limit stopper that abuts against the supporting seat.

[0017] According to one embodiment of the present invention, the rear end of the active swing arm has a rear limit stop that abuts against the mounting base.

[0018] According to one embodiment of the present invention, the bottom of the anti-collision beam is concave.

[0019] According to one embodiment of the present invention, the inclination angle of the pivotal inclined portion is 45°.

[0020] Compared with the prior art, the present invention can achieve the following technical effects:

[0021] The active swing arm is driven by the motor to drive the driven swing arm, so that the pedal body is extended obliquely and exposed on the anti-collision beam; or retracted obliquely and stored in the anti-collision beam, completing the electric control of the pedal. At the same time, it is perfectly integrated with the anti-collision beam, with unique shape, strong reliability and good stability.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Please refer to Figures 1 to 3 , Figure 1 Schematic diagram of an anti-collision tilting electric pedal according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the installation of the pedal body according to an embodiment of the present invention; Figure 3 Schematic diagram of the connection between the active swing arm and the driven swing arm in an embodiment of the present invention.

[0031] As shown in the figure, a tilting electric pedal with anti-collision function includes an anti-collision beam 10, which is fixed to the vehicle body through an anti-collision beam mounting bracket 11; a pedal body 20, which is located on the lower side of the anti-collision beam 10, and has supporting seats 30 fixed at both ends of the inner side, and the supporting seats 30 have a pivotal oblique portion 31; a driven swing arm 40 pivoted to the pivotal oblique portion 31, and the other end of the driven swing arm 40 is pivoted to the mounting base 50; an active swing arm 60 pivoted to the mounting base 50, and the other end of the active swing arm 60 is pivoted to the middle section of the driven swing arm 40 through a transmission connecting rod arm 70; and a motor 80 that drives one of the active swing arms 60 to rotate.

[0032] In one embodiment of the present invention, the bottom of the anti-collision beam 10 is recessed and fixed to both sides of the vehicle body through the anti-collision beam mounting bracket 11, providing protection needs during off-road driving. In addition, during daily use, the decorative appearance is enhanced and the pedal body 20 can be accommodated. The perfect combination of the two ensures reliability, and there is no need to retract the pedal body 20 to the lower side of the vehicle body.

[0033] Specifically, the pedal body 20 is located on the lower side of the anti-collision beam 10, and a support seat 30 is fixed at the front and rear respectively for supporting the pedal body 20, and is obliquely connected to the driven swing arm 40 through the pivot oblique portion 31. At the same time, the active swing arm 60 is pivoted to the middle section of the driven swing arm 40 through the transmission connecting rod arm 70 to form a connecting rod assembly, and the rear ends of the driven swing arm 40 and the active swing arm 60 are pivoted to the mounting base 50. The active swing arm 60 is driven by the motor 80 to rotate and is linked to the transmission connecting rod arm 70, thereby driving the driven swing arm 40 to complete the contraction and extension of the pedal body 20. The present invention uses three lever arms for transmission, which effectively reduces the occupied space and transmission stroke and enhances stability. At the same time, the motor 80 is set on an active swing arm 60 on the front side to link the active swing arm 60 assembly on the rear side to ensure synchronization and high reliability.

[0034] The driven swing arm 40, the active swing arm 60, and the transmission link arm 70 are all arranged to correspond to the inclination of the pivoting bevel 31, enabling the pedal body 20 to be stored at an angle. Preferably, the pivoting bevel 31 is tilted at a 45° angle, facilitating storage within the anti-collision beam 10 and reducing the travel distance. This provides high stability. The active swing arm 60 is driven by the motor 80, which in turn drives the driven swing arm 40, allowing the pedal body 20 to extend obliquely, exposed from the anti-collision beam 10, or retract obliquely, storing within the anti-collision beam 10.

[0035] In one embodiment of the present invention, the supporting seat 30 also has a supporting cross portion 32 fixed to the lower side of the pedal body 20 by bolts. The supporting cross portion 32 extends to connect to the pivot oblique portion 31 to ensure fixation with the pedal body 20. The pivot oblique portion 31 extends from the side of the pedal body 20 on the same side to facilitate the inclined installation of the drive component of the pedal body 20.

[0036] The mounting base 50 of the present invention is angled to correspond to the aforementioned obliquely oscillating pedal body 20. Preferably, a pedal bracket 51 is bolted to the upper side, securing it to the vehicle body and completing the main assembly of the pedal body 20. This bracket is spaced apart from the anti-collision beam mounting bracket 11 to prevent concentrated forces from affecting the strength of the vehicle body brackets. The motor 80 is mounted on the underside of the mounting base 50, facilitating space layout and assembly.

[0037] Furthermore, the mounting base 50 is also equipped with a protective bracket 52 located at the lower side of the motor 80. The protective bracket 52 is equipped with a mudguard to protect the motor 80.

[0038] In a preferred embodiment, the front end of the driven swing arm 40 has a front limit block 91 that stops at the support seat 30, that is, when the pedal body 20 extends downward, the driven swing arm 40 is limited to enhance stability.

[0039] At the same time, the rear end of the active swing arm 60 has a rear limit block 92 that stops at the mounting base 50, that is, when the pedal body 20 is retracted upward, the active swing arm 60 is limited to enhance stability.

[0040] To sum up, the present invention drives the active swing arm 60 through the motor 80, driving the driven swing arm 40, so that the pedal body 20 extends obliquely and is exposed to the anti-collision beam 10; or is retracted obliquely and stored in the anti-collision beam 10, completing the electric control of the pedal, and at the same time perfectly combined with the anti-collision beam 10, with unique shape, strong reliability and good stability.

[0041] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
