Description

Technical Field

[0001] This utility model relates to the field of rear step technology, specifically to the structure of rear step. Background Technology

[0002] In the public's perception, RVs embody the ideal of free travel and making the world their home. However, in reality, their use is fraught with difficulties. The supporting infrastructure for RVs in China is severely lagging behind, with a scarcity of professional campsites, leading to problems such as lack of parking spaces and difficulties in replenishing water and electricity. Furthermore, the high cost of RV maintenance, requiring not only regular professional inspections and repairs but also complex water and electrical system maintenance, presents a double challenge in terms of both technology and cost, deterring many potential consumers. As a result, a large number of RVs are used very infrequently and remain idle for extended periods.

[0003] In contrast, the emergence of family living vehicles offers new possibilities for solving these problems. It adopts an innovative model combining a living compartment and a pickup truck, offering both flexibility and practicality. The pickup truck itself possesses excellent off-road performance and powerful cargo capacity, easily handling various complex road conditions; the modularly designed living compartment allows for free disassembly and installation, enabling multiple uses for one vehicle. In daily life, the pickup truck can serve as a regular family vehicle, meeting daily commuting and cargo transportation needs; when in travel mode, simply assembling the living compartment quickly transforms it into a fully functional living vehicle, catering to both daily use and outdoor travel needs.

[0004] Because the tailgate of a pickup truck is high off the ground, users often need to use boxes, ladders, or other tools to climb into the cargo bed to access the living quarters. This process is cumbersome, time-consuming, and laborious, greatly reducing the convenience and comfort of use. At the same time, there are obvious safety hazards during the climbing process; a slight misstep could lead to slipping, falling, or other accidents, affecting not only the travel experience but also threatening the personal safety of the user. Therefore, we have proposed a rear-mounted step structure to solve the above problems. Utility Model Content

[0005] The present invention aims to provide a rear step structure to solve the problem of cumbersome, time-consuming and laborious operation for users to enter the living compartment, which greatly reduces the convenience and comfort of use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rear step structure, including a flipping component, an extension component, and a step component. The flipping component is hinged to the free end of the tailgate, and the extension component is hinged to the free end of the flipping component. The extension component can be flipped to be parallel or perpendicular to the tailgate through the flipping component. The step component is hinged inside the extension component, and the step component can be flipped to be parallel or perpendicular to the extension component through the hinge point. When the step component, the extension component, and the tailgate are all parallel, the step structure is in a retracted state. When the step component, the extension component, and the tailgate are all perpendicular, the step structure is in a working state.

[0007] The benefits of this solution are as follows: When a user needs to enter the living compartment, the tailgate is first opened to be parallel to the ground. Then, the staircase structure, which is in its retracted state, unfolds, the extension flips to be perpendicular to the ground, and the footrest flips to be parallel to the ground, quickly forming a complete staircase for the user to climb. After use, it can be easily folded away, allowing the footrest, extension, and tailgate to be stored parallel to each other, without the need for additional carrying tools. This simple operation greatly improves convenience and efficiency. In the retracted state, the staircase structure fits snugly against the tailgate, without occupying extra space. It does not affect the normal driving of the pickup truck, nor does it obstruct parking or turning. When the staircase structure is in operation, the flipping parts connect to the tailgate, making the structure more stable and less prone to shaking or slipping. Compared to traditional methods that rely on boxes, ladders, or other auxiliary tools, this solution is safer and faster and more convenient to open and close.

[0008] Preferably, as an improvement, the flipping component includes two storage blocks and a flipping block. The two storage blocks are symmetrically arranged at one end of the tailgate along the transverse direction of the vehicle body. The two flipping blocks are respectively hinged to one end of the storage blocks near the free end of the tailgate, and the flipping blocks can flip the other end out of the tailgate through the hinge point.

[0009] The beneficial effects are as follows: the storage block is used to install the flip block, and the flip block can also be flipped into the storage block, thereby reducing the thickness of the flip part. By flipping the free end of the flip block to extend out of the tailgate, the extension part extends out of the tailgate, making it easier for users to climb.

[0010] Preferably, as an improvement, the extension includes two support rods, which are respectively hinged to the free end of the flip block, and the support rods can be flipped into the storage block for storage.

[0011] The beneficial effects are: by flipping the support rod into the storage block, the thickness between the extension and the flipping part is reduced, thereby reducing the space occupied by the step structure and improving the space utilization of the pickup truck.

[0012] Preferably, as an improvement, the pedal component includes a pedal and two folding rods. The pedal is hinged between the free ends of the two support rods, and the two folding rods are respectively hinged between the pedal and each support rod, and the folding rods can be folded around the center.

[0013] The beneficial effects are as follows: the folding rod is used to limit the pedal. When the pedal is flipped to be perpendicular to the support rod, the folding rod is fully unfolded to pull the pedal. At the same time, a stable triangular structure is formed between the pedal, the folding rod and the support rod, thereby improving the stability of the staircase structure. When the pedal is parallel to the support rod, the folding rod is in a folded state and is completely stored between the pedal and the support rod, reducing the space occupied by the staircase structure.

[0014] Preferably, as an improvement, the flipping component includes two fixed seats and four connecting pieces. The two fixed seats are located at one end of the tailgate along the axial direction of the vehicle body, and the four connecting pieces are symmetrically hinged to both ends of the fixed seats.

[0015] The beneficial effects are as follows: by setting the fixing seat along the axis of the vehicle body at one end of the tailgate, the step structure is located on the side of the vehicle body when it is unfolded, which shortens the length of the vehicle when the step structure is unfolded, making the space at the rear of the vehicle more spacious and regular, making it easier for users to install outdoor tents or outdoor toilets at the rear of the vehicle. The connecting piece is used to connect the tailgate and the folding rod, so that the folding rod can be flipped around the connecting piece to the side of the tailgate.

[0016] Preferably, as an improvement, the extension includes two mounting rods, which are respectively hinged between the free ends of two adjacent connecting pieces, and the mounting rods can be rotated around the fixed base via the connecting pieces.

[0017] Preferably, as an improvement, the stepping component includes several step plates, which are evenly hinged between two mounting rods, and when the step plates are flipped to be perpendicular to the mounting rods, the mounting rods can limit the position of the step plates.

[0018] The beneficial effects are: by setting up several step boards, the span of users when climbing can be reduced, and the safety of users when climbing can be increased. At the same time, the step boards can automatically limit the position when they are unfolded, which improves the installation efficiency when the backup structure is unfolded.

[0023] The following detailed description illustrates the specific implementation method:

[0024] The reference numerals in the accompanying drawings include: tailgate 1, storage block 2, flip block 3, support rod 4, pedal 5, folding rod 6, fixing base 7, connecting piece 8, mounting rod 9, and step plate 10.

[0025] Example 1

[0026] Example 1 is basically as shown in the appendix. Figures 1-2 As shown, Figure 1 The tailgate step structure shown includes a flip-up component, an extension component, and a step component. The flip-up component includes two storage blocks 2 and a flip-up block 3. The two storage blocks 2 are symmetrically fixed to the upper sides of the tailgate 1 along the transverse direction of the vehicle body. The storage blocks 2 are U-shaped. The two flip-up blocks 3 are respectively hinged to the upper front side of the storage blocks 2. The flip-up blocks 3 are rectangular blocks and can be flipped into the storage blocks 2. The other end of the flip-up blocks 3 can be flipped out of the tailgate 1 through the hinge point. The extension component includes two support rods 4, which are respectively hinged to the tailgate 1. At the free end of the flipping block 3, and with the support rod 4 able to flip through the flipping block 3 into the storage block 2 for storage, the step component includes a pedal 5 and two folding rods 6. The pedal 5 is hinged between the free ends of the two support rods 4. One end of each of the two folding rods 6 is hinged to both sides of the pedal 5, and the other end is hinged to the inner wall of the adjacent support rod 4. The middle of the folding rod 6 is hinged and can be folded around the hinge point. When the folding rod 6 is in the folded state, and the pedal 5, support rod 4, and tailgate 1 are all parallel to each other, the step structure is in the following position: Figure 2 The staircase structure is in operation when the folding rod 6 is in the unfolded state, and the step, extension and tailgate 1 are all perpendicular to each other.

[0027] In this embodiment, the hinge connection method for all two structures is as follows: the rotating shaft is fixedly connected to one of the structures, and the rotating shaft passes through the other structure and is rotatably connected to the other structure.

[0028] The specific implementation process is as follows:

[0029] When the user needs to open the ladder structure, first unlock the tailgate 1 and flip it to be parallel to the ground. Then, flip the support rod 4 out of the storage block 2 by flipping the pedal 5, so that the support rod 4 is perpendicular to the ground. Then flip the pedal 5. At the same time as the pedal 5 flips, the folding rod 6 unfolds around the hinge point. When the pedal 5 is perpendicular to the support rod 4, the folding rod 6 is fully unfolded and forms a stable triangular structure with the pedal 5 and the support rod 4. Finally, the pedal 5 forms a flat surface that can be stepped on. The entire ladder structure is fully unfolded and enters the working state, allowing the user to climb into the living compartment.

[0030] When the user needs to fold up the step structure, first flip the pedal 5 so that it is parallel to the support rod 4. During the flipping of the pedal 5, the folding rod 6 folds around the hinge point. After the folding rod 6 is folded up, the pedal 5 is completely stored between the support rods 4. Then, the support rod 4 is flipped up so that the support rod 4 and the pedal 5 are flipped up to the top of the tailgate 1. The support rod 4 and the flipping block 3 are both stored in the storage block 2. Finally, the user closes the tailgate 1 to complete the storage of the step structure. In this solution, the user does not need to carry any additional auxiliary tools. The operation is simple and greatly improves the convenience and efficiency of use.

[0031] Example 2

[0032] Example 2 is based on the same principle as Example 1, the difference being: Figure 3 The flip-up component shown includes two fixed seats 7 and four connecting pieces 8. The two fixed seats 7 are fixedly installed on the upper left side of the tailgate 1 along the axial direction of the vehicle body. The four connecting pieces 8 are symmetrically hinged to the front and rear ends of the fixed seats 7. The extension component includes two mounting rods 9, which are rectangular tubes. The two mounting rods 9 are respectively hinged between the free ends of two adjacent connecting pieces 8, and the mounting rods 9 can be flipped around the fixed seats 7 through the connecting pieces 8. The step component includes several step plates 10. The two right corners of the step plates 10 have rectangular openings. When the step plate 10 is perpendicular to the mounting rod 9, the rectangular openings can abut against the outer wall of the mounting rod 9. Connecting ears are fixedly installed at the rectangular openings by welding, and the connecting ears are respectively hinged to the opposite end of the mounting rod 9. In this embodiment, there are three step plates 10, which are evenly hinged between two mounting rods 9. When the step structure is stored, it is as follows: Figure 4 As shown, each step plate 10 is rotated around the connecting ear until it is parallel to the mounting rod 9, and the step plate 10 abuts against the outer wall of the mounting rod 9. Then, the mounting rod 9 is rotated around the fixing seat 7 to the upper end of the tailgate 1. Finally, the staircase structure is stored by closing the tailgate 1. In this solution, the unfolded staircase structure is located on one side of the vehicle body, which shortens the length of the vehicle when the staircase structure is unfolded, making the space at the rear of the vehicle more spacious and regular, which makes it easier for users to install outdoor tents or outdoor toilets at the rear of the vehicle.
