[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] The terms "top surface," "bottom surface," and "base surface" refer to the normal operating state of the pedal structure and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0019] like Figure 1-3 As shown, a double-layer pedal structure for a bumper includes a bumper body 1. The bumper body 1 is connected to a first pedal 2 via a flip bracket 5. The flip bracket 5 is configured to drive the first pedal 2 to switch between a horizontal and a vertical state. The first pedal 2 has a second receiving portion 202. A flip-out connecting plate 3 is disposed within the second receiving portion 202. A flip-out second pedal 4 is disposed on the connecting plate 3. The second pedal 4 has a closed state and an open state. In the closed state, the connecting plate 3 and the second pedal 4 are folded and stored within the second receiving portion 202. In the open state, both the first pedal 2 and the second pedal 4 are horizontally arranged and vertically distributed. The first pedal 2 and the second pedal 4 are connected to each other via the connecting plate 3.

[0020] The aforementioned pedal structure is mounted on the truck's front bumper for the driver to climb onto for easy vehicle maintenance. During normal truck use, the first pedal 2 flips upwards to a vertical position, and the second pedal 4 and connecting plate 3 fold together and then flip upwards to a vertical position, thus retracting the second pedal 4 and connecting plate 3 into the second receiving portion 202. This closes the first pedal 2, second pedal 4, and connecting plate 3, allowing the vehicle to drive normally. The folded first pedal 2 and connecting plate 3 have a smooth transition between their outer surfaces, forming a relatively flush surface, thereby improving the vehicle's aesthetics and reducing wind resistance. When the front of the vehicle needs maintenance, the first pedal 2 and the second pedal 4 need to be opened. The opening steps are as follows: First, flip the first pedal 2 downwards 90 degrees to a horizontal position. Then, flip the folded connecting plate 3 and the second pedal 4 downwards together 90 degrees to a vertical position. Finally, flip the second pedal 4 downwards 90 degrees to a horizontal position. This completes the opening steps. The opened second pedal 4 is located below the first pedal 1, and the two are connected by the connecting plate 3. In this way, the lower second pedal 4 can reduce the span when the driver climbs onto the first pedal 2, thereby improving the safety and convenience of the driver's climbing.

[0021] Further improvements include, for example Figure 2 and 3 As shown, the bumper body 1 has a first receiving portion 102 for the first pedal 2 to enter, and a locking element is also provided between the first pedal 2 and the bumper body 1. Specifically, the first receiving portion 102 is a notch provided on the bumper body 1, the shape of which matches the shape of the first pedal 2 so that it can be perfectly accommodated; the locking element includes a latch 101 fixed to the inner wall of the first receiving portion 102 and a lock body 201 fixed to the first pedal 2. When the first pedal 2 is retracted, the latch 101 and the lock body 201 lock each other to achieve a fixed connection between the first pedal 2 and the bumper body 1. When the first pedal 2 needs to be opened, it can be unlocked directly with a key.

[0022] Further improvements include, for example Figure 3 As shown, one end of the flip bracket 5 is rotatably connected to the back of the bumper body 1, and the other end of the flip bracket 5 is fixedly connected to the first pedal 2. The flip bracket 5 has a hook-shaped part 501 in the middle. When the first pedal 2 is in a horizontal state, the hook-shaped part 501 abuts against the bumper body 1. When the first pedal 2 is flipped to a horizontal state, the hook-shaped part 501 abuts against the back of the bumper body 1, so that the flip bracket 5 and the bumper body 1 form a mutual limiting relationship, thereby restricting the first pedal 2 from continuing to flip downward, thus keeping the first pedal 2 in a horizontal state, so as to facilitate the driver to climb and step on it.

[0023] Further improvements include, for example Figure 4 and 5 As shown, a hinge seat 205 is provided on the inner wall of the second accommodating part 202 near the flip bracket 5, and a hinge bracket 303 is provided on the connecting plate 3. The hinge bracket 303 is rotatably connected to the hinge seat 205. The middle part of the hinge bracket 303 has an abutment part 304. When in the open state, the abutment part 304 abuts against the inner wall of the second accommodating part 202. The second receiving portion 202 is a notch formed on the first pedal 2. The notch is located on the side of the first pedal 2 away from the flip bracket 5, and the shape of the notch matches the shape of the connecting plate 3. The hinge seat 205 and the hinge bracket 303 are connected to each other by a hinge shaft, so that the connecting plate 3 can rotate around the axis of the hinge shaft. In the open state, the first pedal 2 is in a horizontal state, and the connecting plate 3 is flipped down 90 degrees and is in a vertical state. At this time, the abutment portion 304 abuts against the inner sidewall of the second receiving portion 202, and the top surface of the connecting plate 3 abuts against the bottom surface of the first pedal 2. This positions the connecting plate 3 to limit the rotation angle of the connecting plate 3 and keep it in a vertical state, thereby improving the stability of the double-layer pedal structure in the open state.

[0024] Further improvements include, for example Figure 5 and 6 As shown, the second pedal 4 is connected to the side of the connecting plate 3 away from the bumper body 1 via a hinge 305. In the open state, the side of the second pedal 4 adjacent to the hinge 305 abuts against the side of the connecting plate 3 away from the bumper body 1. The hinge 305 is designed to support the flipping of the second pedal 4. In the open state, the second pedal 4 flips down 90 degrees to reach a horizontal position. At this time, the second pedal 4 abuts against the connecting plate 3 to limit the downward flipping angle of the second pedal 4, so that it can remain in a horizontal position after opening, providing stable support for the driver's pedaling.

[0025] Further improvements include, for example Figure 5 As shown, the connecting plate 3 has a recess 301 for the second pedal 4 to enter. The recess 301 is designed to accommodate the folded second pedal 4, thereby reducing the volume of the second pedal 4 and the connecting plate 3 after folding, and facilitating subsequent storage inside the second receiving part 202.

[0026] Further improvements include, for example Figure 4-5As shown, the first pedal 2 is also provided with a fixing component. When closed, the connecting plate 3 and the second pedal 4 are both fixedly connected to the first pedal 2 through the fixing component. Specifically, the fixing component includes a fixing rod 203. One end of the fixing rod 203 is rotatably connected to the first pedal 2, and the other end of the fixing rod 203 extends to the inner side of the second receiving part 202. The connecting plate 3 and the second pedal 4 are both detachably connected to the fixing rod 203. The specific connection structure is as follows: the connecting plate 3 and the second pedal 4 are both provided with threaded holes 302, and the fixing rod 203 is provided with a hand screw 204 that is threadedly connected to the threaded holes 302.

[0027] In the above pedal structure, when the first pedal 2, connecting plate 3, and second pedal 4 are all retracted, they are connected to the threaded hole 302 by the hand-tightening screw 204, thereby connecting the second pedal 4 and the connecting plate 3 to the fixing rod 203. This achieves a fixed connection between the first pedal 2, the connecting plate 3, and the second pedal 4, thus fixing the connecting plate 3 and the second pedal 4 in the closed state to prevent them from loosening when the vehicle is in motion. When the second pedal 4 is opened, the connecting plate 203 can be rotated to move the connecting plate 203 away from the range of the second receiving part 202, preventing the driver from colliding with the connecting plate 203 when stepping on the first pedal 2 and the second pedal 4, thus improving safety.
