Description

Technical Field

[0001] This utility model relates to the field of car carrier pedal technology, specifically a high-stability car carrier pedal assembly. Background Technology

[0002] The step assembly of a car carrier is an extension platform that can be pulled out or flipped up and installed on the bottom shelf of the car carrier rack. The main rack of the car carrier has a fixed length. In order to load an extra car, especially when the main rack space is full, an additional extension platform is needed. The step assembly is this extension platform. When pulled out, it can create an extra parking space on the bottom shelf for loading the last car. It is usually designed at the rear of the bottom shelf because the upper shelf space is limited and cannot be extended forward or backward. The bottom shelf is close to the ground and has enough vertical space for pulling out without affecting the overall height of the vehicle.

[0003] Traditional single-layer pull-out pedals can only carry one more vehicle at a time, reaching a bottleneck in space utilization. In pursuit of profit, illegal modifications such as "airplane pedals" may occur, posing serious safety hazards. When driving unloaded, the extended pedals or brackets do not generate any benefit. Traditional steel pedal assemblies are very bulky, and their own weight will encroach on the valuable legal load limit, resulting in "the vehicle being carried weighing less than the vehicle itself," increasing vehicle length and weight, leading to increased wind resistance and fuel consumption. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable car carrier pedal assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes two side support frames, with a second folding pedal layer and a bottom folding pedal layer rotatably arranged between the side support frames. An upper support frame and a lower support frame are connected between the side support frames corresponding to the second and bottom folding pedal layers. A drive folding mechanism is connected to the inner side of both the second and bottom folding pedal layers. Round shafts are connected to both sides of both the second and bottom folding pedal layers, with one end of each shaft extending through into the side support frame and connected to a sprocket. A chain is sleeved between the sprockets. A guide assembly and an electric latch are connected to one side of the inner wall of each side support frame, with the guide assembly located between the chains. A speed reducer is connected to one side of each side support frame, and a drive motor is connected to one side of each speed reducer. The output end of the speed reducer extends through into the side support frame and is connected to the round shaft.

[0006] Preferably, a dividing roller is rotatably provided on one side of the inner wall of the side support frame, and the dividing roller is located between the chains.

[0007] Preferably, each side of the side support frame is rotatably provided with a connecting arm, each side of the side support frame is connected with a positioning bolt, and each end of the connecting arm is connected with a positioning pin.

[0008] Preferably, a connecting plate is connected to one side of each side support frame.

[0009] Preferably, the bottom folding pedal layer includes an inner folding plate, an extension plate is rotatably provided on one side of the inner folding plate, multiple sets of wheel platforms are connected to the top of the extension plate, an insertion hole is opened at the top of the inner folding plate corresponding to the wheel platform, the drive folding unit is connected and disposed between the inner folding plate and the wheel platform, and the second folding pedal layer has the same structure as the bottom folding pedal layer.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5This utility model provides a technical solution: it includes two side support frames 1, with a second-layer folding pedal layer 4 and a bottom folding pedal layer 5 rotatably arranged between the side support frames 1. An upper support connecting frame 2 and a lower support connecting frame 3 are connected between the side support frames 1 corresponding to the second-layer folding pedal layer 4 and the bottom folding pedal layer 5. A drive folding unit 55 is connected to the inner side of the second-layer folding pedal layer 4 and the bottom folding pedal layer 5. A round shaft is connected to both sides of the second-layer folding pedal layer 4 and the bottom folding pedal layer 5, and one end of the round shaft extends through into the side support frame 1 and is connected to a sprocket 8. A chain 9 is sleeved and connected between the sprockets 8. A guide component 11 and an electric pin 12 are connected to one side of the inner wall of the side support frame 1. The guide component 11 is located between the chains 9. A reducer 16 is connected to one side of the side support frame 1. A drive motor 17 is connected to one side of the reducer 16. The output end of the reducer 16 extends through into the side support frame 1 and is connected to the round shaft.

[0019] Reference Figure 2 and Figure 4 As shown in the attached figure, a dividing roller 10 is rotatably installed on one side of the inner wall of the side support frame 1. As can be seen from the attached figure, the dividing roller 10 is rotatably installed between two side plates. The side plates are fixed to one side of the inner wall of the side support frame 1. The dividing roller 10 is located between the chains 9. The chains 9 are arranged in a figure-eight shape. The dividing roller 10 can separate the chains 9 at the intersection to prevent the chains 9 from rubbing against each other.

[0020] Reference Figure 1 and Figure 2 As shown, each side of the side support frame 1 is rotatably equipped with a connecting arm 13, and each side of the side support frame 1 is connected with a positioning bolt 14. Each end of the connecting arm 13 is connected with a positioning pin 15. The inner folding plate 51 in the bottom folding pedal layer 5 and the same component in the second folding pedal layer 4 are provided with pin holes on both sides. After the second folding pedal layer 4 and the bottom folding pedal layer 5 are opened, the positioning pin 15 is inserted into the corresponding pin hole, thereby ensuring the support effect of the second folding pedal layer 4 and the bottom folding pedal layer 5.

[0021] Reference Figure 1 As shown, each side of the side support frame 1 is connected to a connecting plate 18, which can be used to connect and install this device with the support frame of the car carrier, thereby ensuring the integrity of the whole.

[0022] Reference Figure 1 and Figure 3As shown, the bottom folding pedal layer 5 includes an inner folding plate 51. An extension plate 52 is rotatably mounted on one side of the inner folding plate 51. Multiple sets of wheel platforms 53 are connected to the top of the extension plate 52. An insertion hole 54 is opened at the top of the inner folding plate 51 corresponding to the wheel platform 53. A drive folding unit 55 is connected and mounted between the inner folding plate 51 and the wheel platform 53. The second-layer folding pedal layer 4 has the same structure as the bottom folding pedal layer 5. When the drive motor 17 is started, it drives the round shafts on both sides of the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 through the reducer 16, thereby opening the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 in the first step. Then, the drive folding unit 55 is started to open the corresponding extension plate, completing the pedal opening. As can be seen from the attached diagram, when the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 are opened to a certain angle, the upper support connecting frame 2 and the lower support connecting frame 3 will lock the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 to prevent them from rotating too much. Moreover, the extension plate 52 and the inner folding plate 51 are made of high-strength metal and have multiple cutouts on their surfaces to reduce their weight. The wheel platform 53 can limit the movement of the transported wheels, and the cutout holes can be used to further bind and limit the wheels with ropes. When folded, the wheel platform 53 will be locked into the insertion hole 54 to reduce space occupation.

[0023] Reference Figure 3 As shown, the top of the extension plate 52 is connected to multiple sets of limiting blocks 6, and the top of the inner folding plate 51 is provided with a slot 7 corresponding to the limiting block 6. By setting the limiting block 6, the friction with the vehicle tire can be increased, which facilitates the loading of the vehicle. When folded, the limiting block 6 can be locked into the slot 7 to reduce space occupation.

[0024] Reference Figure 5 As shown, the drive folding unit 55 includes a mounting bracket 551 connected to one side of the inner folding plate 51. A servo motor 552 is connected to the inner side of the mounting bracket 551. A drive gear 553 is connected to the output end of the servo motor 552. A driven gear 554 is rotatably mounted on one side of the mounting bracket 551. A cam 555 is connected to one side of the driven gear 554. A connecting bolt 556 is connected to one side of the cam 555. The connecting bolt 556 is fixedly connected to the extension plate 52. When the inner folding plate 51 is opened, the servo motor 552 drives the drive gear 553, which in turn drives the cam 555 to rotate through the driven gear 554. Through the connection between the connecting bolt 556 and the extension plate 52, the extension plate 52 is rotated and opened. At the same time, the drive folding unit 55 is located in the middle of the bottom folding pedal layer 5 and does not occupy the usable space.

[0025] Reference Figure 4As shown, the guide assembly 11 includes an I-beam 111 fixedly mounted on one side of the inner wall of the side support frame 1. Two sets of separator wheels 112 are rotatably mounted between the I-beams 111. Downward rolling balls 113 are rotatably mounted on both sides of the top of the I-beams 111. One side of the separator wheel 112 abuts against the chain 9, and the bottom end of the downward rolling ball 113 abuts against the chain 9. The two separator wheels 112 guide the chain 9, while the downward rolling ball 113 located above presses down on the chain 9 to ensure the stability of its meshing connection with the sprocket 8.

[0026] The implementation principle of this application is as follows: When in use, this utility model is installed on one side of the support frame for carrying the vehicle on a car carrier via the connecting mounting bracket 18. When needed, the drive motor 17 is started. Due to the setting of the chain 9, the sprocket 8 can be driven to rotate in opposite directions, thereby driving the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 to open initially. Then, the drive folding unit 55 is used to fully open the device, allowing the vehicle to be transported to be driven onto the support frame via the bottom folding pedal layer 5. After opening, the connecting arm 13 is connected to the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 via the positioning pin 15, thereby ensuring support. The drive folding unit 55 can be used to carry the vehicle. When not in use, the second-layer folding pedal layer 4 and the bottom folding pedal layer 5 can be folded and stored to reduce space occupation and at the same time block the tail of the support frame, providing a protective effect.
