Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to an electric pedal for automobiles. Background Technology

[0002] Electric car pedals are fixed to the door sill beam, located below the door, and are automotive components used to provide foot support for getting in and out of high-chassis vehicles. For example, patent application CN216659758U discloses an integrated retractable electric pedal using a swing arm structure to extend or retract the pedal. However, existing electric car pedals require a relatively large space, and when retracted, the bottom structure may not completely fold into the car chassis, potentially causing damage during driving on complex terrain and affecting the lifespan of the electric car pedal. Utility Model Content

[0003] In view of the problems in the prior art, this utility model proposes an electric car pedal that can minimize the height of the electric car pedal when it is retracted, without affecting the extension length of the pedal.

[0004] The technical solution adopted by this utility model is as follows: an electric pedal for automobiles includes a pedal body, a drive mechanism, and two sets of linkage mechanisms fixedly connected to the same side of the pedal body. Each set of linkage mechanisms includes a mounting bracket mounted on the vehicle body. A driving rod and a driven rod are hinged on the mounting bracket. The other ends of the driving rod and the driven rod are hinged to an L-shaped pedal bracket. The driving rod, the driven rod, the mounting bracket, and the pedal bracket form a planar four-bar linkage structure. The output shaft of the drive mechanism is connected to the driving rod of one set of linkage mechanisms to drive the driving rod to rotate, thereby causing the pedal bracket to perform translational movement under the constraint of the four-bar linkage structure.

[0005] Preferably, one end of the driven rod connecting to the pedal bracket has a curved section, and the non-curved section of the driven rod is in close contact with the pedal body when the pedal is fully retracted, reducing the volume of the pedal after retraction and making the pedal body and the driven rod fit tightly together, thereby saving space.

[0006] Preferably, when the pedal is fully retracted, the pedal body is partially embedded in the space formed between the non-bent section of the driven rod and the pedal bracket, which optimizes the space occupied by the pedal after it is retracted, allowing the pedal body to be better hidden under the vehicle and avoid scratches and damage.

[0007] Preferably, the L-shaped pedal bracket is divided into an integrally connected transmission part and a connecting part, with the transmission part and the connecting part forming an angle of 130°-150°. The two ends of the transmission part are hinged to the driving rod and the driven rod, and the connecting part is fixedly connected to the pedal body. This shape of pedal bracket ensures that the pedal remains parallel to the ground during extension and retraction.

[0008] Preferably, the mounting bracket is provided with a first hinge shaft and a second hinge shaft, and the transmission part of the pedal bracket is provided with a third hinge shaft and a fourth hinge shaft at both ends; the two ends of the driving rod are respectively hinged to the first hinge shaft and the third hinge shaft, and the two ends of the driven rod are respectively hinged to the second hinge shaft and the fourth hinge shaft, which simplifies the linkage structure.

[0009] Preferably, the distance between the first hinge shaft and the third hinge shaft is greater than the distance between the second hinge shaft and the fourth hinge shaft. This arrangement can make the overall height smaller when the pedal is retracted, reduce the wear of mechanical parts, and extend the service life.

[0010] Preferably, the drive mechanism is a reversible motor, and the rotating shaft connecting the mounting bracket and the drive rod is connected to the output shaft of the drive mechanism. During the retraction or extension of the pedal, the rotating shaft connecting the mounting bracket and the drive rod is fixed relative to the drive rod and rotates relative to the mounting bracket; this ensures that the output power of the motor can be effectively transmitted to the drive rod, thereby achieving precise control of the pedal.

[0011] Preferably, the connecting part of the pedal bracket is provided with a weight-reducing structure. The weight-reducing structure includes multiple hollow long slots extending along the length of the connecting part. The weight-reducing structure can reduce the weight of the pedal bracket, thereby reducing the load on the entire pedal device, without affecting the structural strength and stability of the pedal bracket.

[0012] Preferably, an upward-facing baffle is fixedly provided on the inner side of the pedal body to prevent a person's foot from extending too far in and causing a safety hazard. The baffle is located between two sets of linkage mechanisms to prevent the pedal from interfering with the linkage mechanisms during the retraction or extension process.

[0013] Preferably, the pedal body remains parallel to the ground during the retraction or extension of the pedal, in order to minimize the height of the pedal when it is retracted.

[0014] This invention uses a four-bar linkage to drive an L-shaped pedal bracket to perform translational movement, ensuring that the connecting part of the pedal bracket used to fix the pedal body remains parallel to the ground during extension and retraction. By utilizing the bent end of the driven rod to cooperate with the connecting part of the pedal bracket parallel to the ground, a compact space is formed to accommodate the pedal body when it is retracted, significantly reducing the loss of ground clearance of the entire vehicle and effectively avoiding chassis collisions under complex road conditions.

Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The electric running board is installed in the pre-reserved mounting space on the side of the car body, located below the door. For example... Figure 1-5 This embodiment discloses an electric automotive pedal, comprising a pedal body 1, a linkage structure 2, and a drive mechanism 3. The linkage structure 2 has two sets, each set including a driving rod 21, a driven rod 22, a mounting bracket 23, and a pedal support 24. Figure 4 The mounting bracket 23 is equipped with a first hinge shaft 25 and a second hinge shaft 26. The pedal bracket 24 is L-shaped, and the L-shaped pedal bracket 24 can be divided into a transmission part 241 and a connecting part 242 at a certain angle from the bend. Figure 5 The angle is 145°. A third hinge shaft 27 is mounted at the end of the transmission part 241, and a fourth hinge shaft 28 is mounted at the bend of the pedal bracket 24. One end of the driving rod 21 is hinged to the mounting bracket 23 via the first hinge shaft 25, and the other end is hinged to the pedal bracket 24 via the third hinge shaft 27. One end of the driven rod 22 is hinged to the mounting bracket 23 via the second hinge shaft 26, and the other end is hinged to the pedal bracket 24 via the fourth hinge shaft 28. The distance between the first hinge shaft 25 and the third hinge shaft 27 is greater than the distance between the second hinge shaft 26 and the fourth hinge shaft 28.

[0024] The driving rod 21, driven rod 22, mounting bracket 23, and pedal bracket 24 form a planar four-bar linkage. One of the two sets of linkage structures 2 is connected to the output shaft of the drive mechanism 3. Specifically, the output shaft of the drive mechanism 3 is fixedly connected to the first hinge shaft 25 of one set of linkage structures 2. The first hinge shaft 25 is fixed relative to the driving rod 21 but rotatably connected to the mounting bracket 23. The drive mechanism 3 drives the driving rod 21 to rotate around the first hinge shaft 25 through the first hinge shaft 25. Due to the planar four-bar linkage, the driven rod 22 remains parallel to the driving rod 21 and rotates synchronously. The rotation axis of the driven rod 22 is the second hinge shaft 26. The pedal bracket 24 translates under the driving action of the driving rod 21 and the guiding action of the driven rod 22 but does not rotate. Therefore, the connecting part 242 of the pedal bracket 24 is always parallel to the ground. The drive mechanism 3 can output positive and negative torque. When the drive mechanism 3 outputs positive torque, the pedal bracket 24 extends outward; when the drive mechanism 3 outputs negative torque, the pedal bracket 24 retracts inward. The drive mechanism 3 is a motor. A speed reducer is also installed at the output shaft of the motor, and the output shaft of the motor is connected to the first hinge shaft 25 through the speed reducer.

[0025] Multiple connection holes are provided on the connecting portion 242 of the pedal bracket 24 for fixed connection with the pedal body 1. The pedal brackets 24 of the two sets of linkage structures 2 are connected to the same pedal body 1, realizing multi-point fixation of the pedal body 1 and preventing the pedal body 1 from tilting to one side under pressure. Specifically, each connecting portion 242 of the pedal bracket 24 is provided with four connection holes. The connecting portion 242 of the pedal bracket 24 is provided with multiple weight-reduction structures, which are specifically manifested as hollows and grooves. The hollows are mostly long grooves along the length of the connecting portion 242, and the hollow long grooves are all located in the part that contacts the pedal body 1.

[0026] Approximately one-fifth of the length of the driven rod 22, which connects to the fourth hinge shaft 28, bends downwards at about 25°, thus providing space for the pedal body 1 to retract. The remaining portion serves as the main body of the driven rod 22, remaining substantially parallel to the driving rod 21. This bending arrangement creates a space between the main body of the driven rod 22 and the connection portion 242 of the pedal bracket 24. This space is at the same height as or slightly higher than the pedal body 1. When the entire structure is fully retracted, a portion of the pedal body 1 can fit into this space, further reducing the width of the entire device. The pedal body 1 can be completely retracted into the pedal mounting space on the side of the vehicle body. The upper surface of the driven rod 22 has a protruding structure, and two limiting blocks are installed below the driving rod 21, both of which cooperate with the protruding structure of the driven rod 22. When the entire structure is fully retracted, the first limiting block 211 of the driving rod 21 abuts against the protruding structure of the driven rod 22, and when the entire structure is fully extended, the second limiting block 212 of the driving rod 21 abuts against the protruding structure of the driven rod 22.

[0027] The drive mechanism 3 is mounted on a mounting bracket 23 of one set of linkage structures 2. The other mounting bracket 23 of the linkage structures 2 does not have the drive mechanism 3 mounted on it. The mounting bracket 23 is fixedly connected to the vehicle body. The mounting bracket 23 without the drive mechanism 3 is connected to the vehicle body with three screws, while the mounting bracket 23 with the drive mechanism 3 is connected with the vehicle body with four screws. When the electric pedal is retracted, the drive mechanism 3 is positioned between the vehicle body and the pedal body 1. A baffle 11 is fixedly installed on the inner side of the pedal body 1 to prevent the driver or passenger from getting their feet stuck when entering the vehicle. The baffle 11 is positioned between the two sets of linkage structures 2 and does not obstruct the retraction of the device.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
