Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically, to an electric tailgate pedal mechanism for a tailgate of a pickup truck. Background Art

[0002] A pickup truck tailgate step is an additional part designed specifically for pickup trucks to improve the convenience and safety of using the vehicle body. Such steps are usually installed under the tailgate or cargo bed of a pickup truck, making it easier for people to get in and out of the cargo bed, especially when loading or unloading cargo.

[0003] There are many types of tailgate steps for pickup trucks, including fixed steps, which are permanently installed on the vehicle body and provide a foothold whether the tailgate is open or not; folding steps, which can be folded and put away when not in use to avoid taking up space or generating unnecessary resistance and noise during driving; and electric steps, which are provided as options for some high-end models or modified parts. These steps can be automatically extended or retracted and automatically adjust their position according to the vehicle body status (such as opening and closing the door). These steps not only improve practicality, but sometimes also have decorative effects, such as being made of stainless steel, carbon fiber texture or other materials to enhance the appearance of the vehicle body.

[0004] A self-retractable electric pedal for a car trunk with a publication number of CN116605145A comprises a pedal, a telescopic mechanism and a driving mechanism. The telescopic mechanism comprises a bottom bracket, an active arm, an auxiliary arm and a top bracket. One end of the bottom bracket is fixedly connected to the pedal, and the other end is provided with two pairs of mounting holes. One end of each of the active arm and the auxiliary arm is rotatably connected to the two mounting holes. The other ends of the active arm and the auxiliary arm are rotatably connected to the two ends of the top bracket respectively. The top bracket is detachably connected to the bottom side of the car trunk. The bottom bracket, the auxiliary arm, the top bracket and the active arm together constitute a planar four-bar linkage. The driving mechanism is fixedly connected to the top bracket and is used to drive the active arm to flip. When the angle between the active arm and the bottom bracket reaches the minimum, the electric pedal is in a retracted state. When the angle between the active arm and the bottom bracket reaches the maximum, the electric pedal is in an unfolded state. The driving mechanism drives the active arm to rotate, and then drives the telescopic mechanism to retract, so as to realize the trajectory control of the pedal, so that the electric pedal can switch freely between the unfolded state and the retracted state.

[0005] However, since the bottom bracket of the electric pedal is a plate-like structure, the bottom bracket can only be installed at the bottom of the vehicle body, which is very inconvenient to install. Utility Model Content

[0059] In view of the limitation of the existing electric tailgate pedal base bracket, that is, the plate-like structure restricts its installation position and method, the present application proposes a more flexible and efficient electric tailgate pedal mechanism.

[0060] The electric tailgate pedal mechanism of the present application is described in detail through the following embodiments.

[0061] Embodiment 1:

[0062] like Figure 1-Figure 8 As shown, in this embodiment, an electric tailgate pedal mechanism includes: a mounting base 100, which is arranged on a vehicle body 10; a pedal 200; and a telescopic assembly 300, which is arranged on the mounting base 100 and is used to drive the pedal 200 to open and close.

[0063] The mounting base 100 includes: a bottom plate 110; a side plate 120, which is disposed on one side of the upper end of the bottom plate 110; and a bracket 130, which is disposed at the bottom of the bottom plate 110 and is used to fix the telescopic assembly 300;

[0064] The upper end of the bottom plate 110 is formed with a mounting chamber, and the side plate 120 is provided with mounting holes 121 for fixing the side plate 120 to the vehicle body 10 by bolts.

[0065] The bottom plate 110 is the foundation of the entire mounting base 100, and it forms a plane for supporting the pedal 200 and other components. The side plate 120 is disposed on one side of the upper end of the bottom plate 110, and its main function is to provide additional structural stability and protect the internal components from external factors. The mounting holes 121 on the side plate 120 are used to be fixed to the vehicle body 10 by bolts to ensure a stable connection between the mounting base 100 and the vehicle body.

[0066] On the one hand, the combination design of the new base plate 110 and the bracket 130 allows the mounting base 100 to be more flexibly installed at different positions of the vehicle body, which not only simplifies the installation process, but also increases the range of installation position options to meet the needs of different vehicle models.

[0067] On the other hand, the structural stability of the mounting base 100 is enhanced, especially when the vehicle body is in motion, and damage caused by vibration or external force can be effectively reduced.

[0068] In this embodiment, it is optimized that a first inclined support plate 140 is disposed between the side plate 120 and the bottom plate 110 .

[0069] The first oblique support plate 140 is located between the side plate 120 and the bottom plate 110, and extends from the lower part of the side plate 120 to the inner side or outer side of the bottom plate 110 to form an oblique support. This design utilizes the principle of geometric stability and improves the overall structural strength of the mounting base 100 through the rigidity of the triangular structure.

[0070] The first inclined support plate 140 can guide and disperse the pressure from the side plate 120 and the bottom plate 110 so that it is more evenly distributed on the entire structure, preventing local overload and reducing stress concentration, thereby improving the reliability and safety of the entire electric tailgate pedal mechanism.

[0071] In this embodiment, it should be noted that the bracket 130 includes: two ear plates 131, which are spaced apart, and a first rotating shaft a1311 and a first rotating shaft b1312 are disposed between the two ear plates 131; and a motor mounting plate 132;

[0072] A second inclined support plate 133 is disposed between the ear plate 131 , the motor mounting plate 132 and the bottom plate 110 .

[0073] By designing the ear plate 131 into two pieces and setting them at an interval, this layout provides a stable support point for the first rotating shaft a and the first rotating shaft b, ensuring that the telescopic assembly 300 can operate accurately and smoothly.

[0074] The motor mounting plate 132 is the power source of the telescopic assembly 300. It is fixed to a part of the bracket 130, usually the side of the ear plate 131. The design of the motor mounting plate 132 needs to take into account the heat dissipation and waterproofing of the motor 341 and the coordination with other mechanical components to ensure the efficient operation of the entire system.

[0075] The introduction of the second inclined support plate 133 greatly improves the structural stability of the electric tailgate pedal mechanism through an additional triangular structure, especially during dynamic operation, ensuring the accuracy and smoothness of the movement of the pedal 200.

[0076] In the present embodiment, the ear plate 131, the motor mounting plate 132, and the second inclined support plate 133 are optimized to have protrusions 134 extending upward, and the bottom plate 110 is provided with sockets 111 respectively matched with the protrusions 134, and the protrusions 134 are respectively embedded in the sockets 111.

[0077] The cooperation between the protrusion 134 and the socket 111 reduces the need for precise welding or fasteners, making the assembly process simpler and faster. This design, on the one hand, not only reduces the manufacturing cost, but also reduces the possibility of assembly errors and improves production efficiency; on the other hand, by increasing the physical contact area between the components, the rigidity of the entire structure is improved, making the electric tailgate pedal mechanism more stable and reliable in the face of various use conditions. In particular, when the pedal 200 is in the unfolded state, it can more effectively support the weight of the passengers and avoid structural fatigue or damage caused by long-term heavy-load use.

[0078] Embodiment 2:

[0079] This embodiment is a further improvement made on the basis of the first embodiment.

[0080] like Figure 2-Figure 8 As shown, in this embodiment, the telescopic assembly 300 includes: a transmission arm 310, one end of which is connected to the pedal 200, and the other end of which is provided with a second rotating shaft a3111 and a second rotating shaft b3112; an active arm 320, one end of which is provided on the first rotating shaft a1311, and the other end of which is provided on the second rotating shaft a3111; a driven arm 330, one end of which is provided on the first rotating shaft b1312, and the other end of which is provided on the second rotating shaft b3112; a driving part 340, which is provided on the motor mounting plate 132, and the output end of which is connected to the first rotating shaft a1311; a radar system 350, which is provided on the pedal 200; and a controller 360, which is provided on the mounting chamber, including a device for controlling the operating state of the driving part 340;

[0081] The radar system 350 is used to detect obstacles around the pedal 200 and send the detected signals to the controller 360. The controller 360 also controls the operating state of the driving unit 340 according to the signals detected by the radar system 350 to play an anti-collision role.

[0082] The driving unit 340 is mainly composed of a motor 341 and a reducer 342 connected to the motor 341, and the controller 360 is used to control the operating state of the motor 341. Through the forward and reverse rotation of the motor 341, the active arm 320 is rotated, and finally the transmission arm 310 and the pedal 200 are extended and retracted, so that the pedal 200 is opened outward or retracted inward.

[0083] Since the pedal may collide during the opening process, for example, if there are many obstacles at the parking position, if the tailgate is close to the obstacles, the pedal may be easily damaged. For this reason, a radar system 350 is provided. The radar system 350 is installed on the inner side of the pedal and then extends from the side of the pedal. It not only plays a protective role, but also when the pedal is in motion, if the radar system 350 detects an obstacle, it will promptly feedback to the controller 360, indicating that the obstacle is close to the pedal. The controller 360 immediately controls the motor 341 to stop rotating, or controls the motor 341 to rotate in the opposite direction to retract the pedal. At the same time, the controller sends a signal to the vehicle system, causing the vehicle system to emit an alarm prompt sound to remind the owner that the pedal is blocked and cannot be fully opened.

[0084] It should be noted that the controller 360 is installed on the installation chamber, that is, on the upper end surface of the base plate 110. Installing it in this position is not only convenient for installation, but also saves space.

[0085] In this embodiment, it should be noted that both ends of the active arm 320 are fixed to the first rotating shaft a1311 and the second rotating shaft a3111 by bolts; and both ends of the driven arm 330 are fixed to the first rotating shaft b1312 and the second rotating shaft b3112 by bolts.

[0086] The above design facilitates the installation and disassembly of the active arm 320 and the passive arm 330 .

[0087] In this embodiment, it should be noted that the transmission arm 310 includes: two support plates 311, which are symmetrically arranged; a connecting plate 312, which is arranged between the two support plates 311 and is used to connect the two support plates 311; and a mounting plate 313, which is arranged above one end of the two support plates 311;

[0088] The second rotating shaft a and the second rotating shaft b are disposed between the other ends of the two supporting plates 311 ; and the pedal 200 is disposed on the mounting plate 313 .

[0089] The transmission arm 310 includes two support plates 311, which are symmetrically arranged to form a stable base for supporting and guiding the movement of the pedal 200. The symmetrical design ensures uniform distribution of force during the extension and retraction process and reduces structural distortion caused by torque imbalance. The connecting plate 312 is located between the two support plates 311. Its main function is to strengthen the connection between the support plates 311 and provide additional structural stability and rigidity. The mounting plate 313 is arranged above one end of the two support plates 311 to fix the pedal 200. This design ensures the firm installation of the pedal 200, and also provides guidance for the movement trajectory of the pedal 200, avoiding deviation or shaking during the extension and retraction process.

[0090] In this embodiment, it is optimized that sealing covers 314 are further provided on the two support plates 311 for sealing the ends of the second rotating shaft a3111 and the second rotating shaft b3112.

[0091] The main function of the sealing cover 314 is to protect the ends of the second rotating shaft a3111 and the second rotating shaft b3112 from being affected by the external environment, especially to prevent dust, moisture, impurities, etc. from entering the interior of the rotating shaft, which may cause accelerated wear of the rotating shaft, lubrication failure or movement blockage.

[0092] In this embodiment, it should be noted that in order to reduce the weight of the active arm 320 and the passive arm 330 and to ensure the strength of the active arm 320 and the passive arm 330 , a plurality of through slots 323 are provided thereon.

[0093] Embodiment three:

[0094] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0095] like Figure 5-Figure 8 As shown, in this embodiment, the active arm 320 is provided with a first limiting protrusion 321 and a second limiting protrusion 322, and the driven arm 330 is provided with a buffer pad 331;

[0096] When the pedal 200 is closed, the buffer pad 331 abuts against the first limiting protrusion 321;

[0097] When the pedal 200 is opened, the buffer pad 331 abuts against the second limiting protrusion 322 .

[0098] When the pedal 200 is in the closed position, the first limiting protrusion 321 on the active arm 320 contacts the buffer pad 331 on the driven arm 330 to prevent the pedal 200 from being over-closed or rebounding due to external forces, thereby ensuring the stability and safety of the pedal 200 in the closed state.

[0099] When the pedal 200 is fully opened, the second limiting protrusion 322 plays the same limiting role, preventing the pedal 200 from being displaced unnecessarily due to excessive opening or being affected by external forces, thereby ensuring the stability of the pedal 200 in the open state.

[0100] The buffer pad 331 is usually made of elastic material, such as rubber or silicone, and provides a buffering effect when the active arm 320 contacts the driven arm 330, reducing the impact and noise that may be generated by hard contact, while avoiding wear caused by direct collision of metal parts.

[0101] It should be noted that the first limiting protrusion 321 is arranged at the upper middle part of the active arm 320, and the second limiting protrusion 322 is arranged at the lower end part of the active arm 320, so that the rotation angle of the active arm 320 can be larger, so that when the pedal 200 is opened, its upper end surface tends to a horizontal state, which is convenient for people to step on.

[0102] Embodiment 4:

[0103] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0104] like Figure 1 , Figure 2 and Figure 8 As shown, in this embodiment, a plurality of V-shaped anti-skid protrusions 210 are provided on the upper end surface of the pedal 200 , and the anti-skid protrusions 210 are arranged at intervals along the length direction of the pedal 200 .

[0105] The upper surface of the pedal 200 is designed to have a plurality of anti-slip protrusions 210 arranged in a V-shape. These protrusions 134 are spaced apart along the length direction of the pedal 200. This design not only improves the safety of the pedal 200, but also optimizes the user experience.

[0106] Specifically, each anti-slip protrusion 210 is in a V-shape, which can provide friction in multiple directions. Even in slippery conditions, it can effectively increase the friction coefficient between the sole and the contact surface of the pedal 200. Even in rainy, snowy or humid environments, it can ensure the stability of the user when getting on and off the vehicle, greatly reducing the risk of slipping and improving safety.

[0107] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
