[0002] With the development of society, the annual increase in the number of automobiles in use and the increase in labor costs, the application of vehicle tailboards will become more and more common. However, most of the tailboards on the market are installed at the rear of the carriage tailgate, which is inconvenient to use. There are many disadvantages in the existing technology, such as:

[0003] 1) Each time when loading and unloading goods, it is necessary to open and close the carriage tailgate, which is inconvenient to use;

[0004] 2) The space between the tailboard and the tailgate is narrow, and it is easy to accidentally operate and pinch people;

[0005] 3) It increases the weight of the whole vehicle, thus increasing fuel consumption or power consumption. Content of the Utility Model

[0006] The utility model provides a novel structure of an integrated tailgate and tailboard carriage, which belongs to the development trend of future tailboards. By using a high-strength steel tailboard, there is a small door above the rear door frame of the carriage, so there is no need to worry about the height of the goods. The use of multiple water-retaining side sealing strips has better water-retaining performance. The lower sealing strip uses an extruded aluminum alloy strip and the lower sealing strip to cooperate for sealing, preventing the loss of goods and water ingress caused by too large gaps in the lower sealing strip.

[0007] The technical solution of the utility model is realized as follows:

[0008] A novel structure of an integrated tailgate and tailboard carriage includes: a tailboard assembly and a rear door frame. The tailboard assembly includes a tailboard, a lifting arm and a frame.

[0010] A small door is arranged on the rear door frame, and the tailboard is also docked with the small door through compression sealing.

[0011] Further, the rear door frame includes a left column, a right column, an upper cross beam and a lower cross beam. The upper cross beam and the lower cross beam are arranged parallel to each other up and down, and the left column and the right column are arranged parallel to each other left and right. The left column is simultaneously connected to the left end of the upper cross beam and the left end of the lower cross beam, and the right column is simultaneously connected to the right end of the upper cross beam and the right end of the lower cross beam;

[0012] The tailboard stop block is installed on the lower crossbeam, and the tailboard is clamped on the tailboard stop block.

[0013] Furthermore, one or more tailboard stop blocks are provided.

[0014] Furthermore, limit stop blocks are provided at the tops of the left upright column and the right upright column, and the tailboard is pressed against the limit stop blocks.

[0015] Furthermore, the limit stop blocks are made of ethylene propylene diene monomer (EPDM) rubber.

[0016] Furthermore, thin-walled sleeves are provided in the bolt holes of the limit stop blocks.

[0017] Furthermore, a lower sealing structure is provided at the lower ends of the left upright column and the right upright column. The lower sealing structure includes an aluminum alloy strip and a lower sealing strip. The aluminum alloy strip is installed on the lower crossbeam, and the lower sealing strip is installed on the aluminum alloy strip.

[0018] Furthermore, multiple water-blocking side sealing strips are installed below the left upright column, the right upright column and the small door through clamping strips, and both sides of the tailboard are pressed against the multiple water-blocking side sealing strips on both sides.
