[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] The present application provides an automatic folding mechanism, which is mainly used to solve the problem that traditional display board equipment is usually bulky and heavy, which is not convenient for transportation and rapid deployment. In addition, when the display board load is located at the front or rear end of the vehicle, the vehicle may nod or lift during driving, affecting driving stability and safety. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0022] The automatic folding mechanism mainly comprises a carrying plate 1, a display board 2, a connecting rod assembly 3 and a driving assembly 4. The carrying plate 1 is horizontally mounted on a transport vehicle. Two parallel slide rails 11 are mounted on the top of the carrying plate 1. Slide blocks 12 are mounted on the two slide rails 11. An integral connecting plate 13 is connected between the tops of the two slide blocks 12. Two connecting blocks 14 are fixed on the top of the connecting plate 13. The bottom side of the display board 2 is hinged to the tops of the two connecting blocks 14. The connecting rod assembly 3 is connected between the top of the carrying plate 1 and one side of the display board 2. The driving assembly 4 is mounted on the carrying plate 1 and is used to drive one of the slide blocks 12 to slide. The display board 2 can be in a vertical state or a horizontal state by moving the connecting plate 13 and under the connection of the connecting rod assembly 3. When the display board 2 is in a vertical state, the display board 2 is close to the middle part of the carrying plate 1. During the specific installation operation of the device, first, the carrying plate 1 is horizontally mounted at an appropriate position of the transport vehicle to ensure that it is firmly fixed. Two parallel slide rails 11 are mounted on the top of the carrying plate 1. The length and position of the slide rails 11 are based on the The size of the display board 2 and the required range of motion are determined. Secondly, a slider 12 is installed on each slide rail 11. The slider 12 should be able to slide smoothly and fit tightly with the slide rail 11 to ensure that there is no shaking or deviation during the movement. An integrated connecting plate 13 is connected between the tops of the two sliders 12. The connecting plate 13 is strong enough to withstand the weight of the display board 2 and the force generated during movement. Then, two connecting blocks 14 are fixed on the top of the connecting plate 13. The two connecting blocks 14 are used to be hinged with the bottom side of the display board 2 to form a foldable structure. Finally, the connecting rod assembly 3 and the driving assembly 4 are installed to form a complete folding mechanism. Through the design of the slide rail 11, the slider 12, the connecting rod assembly 3 and the driving assembly 4, the display board 2 can be easily converted between the horizontal and vertical states, which greatly saves transportation and storage space. When the display board 2 is in the vertical state, it is close to the middle part of the load-bearing plate 1, which helps to maintain the balance of the entire structure, reduce shaking and unstable factors during transportation, and avoid the phenomenon of the vehicle tilting its head or tail.

[0023] In this example, see Figure 2 and Figure 4The connecting rod assembly 3 is used to achieve stable support and smooth movement of the display board 2 in the automatic folding mechanism. The connecting rod assembly 3 includes a sliding plate 31 that is horizontally arranged and slides on one side of the display board 2. The connecting rod assembly 3 also includes two symmetrically arranged L-shaped rods 32. The openings of the two L-shaped rods 32 are downward and one end is hinged to the top of the bearing plate 1. The other ends of the two L-shaped rods 32 are hinged to the sliding plate 31. When the slider 12 moves, the connecting plate 13 is driven to move. The movement of the display board 2 drives the L-shaped rod 32 and the sliding plate 31 to move, so as to realize the state conversion of the display board 2. The design of the connecting rod assembly 3 provides additional support, so that the display board 2 is more stable during the unfolding and folding process, and the shaking caused by wind or other external factors is reduced. The structural design of the sliding plate 31 and the L-shaped rod 32 makes the movement of the display board 2 smoother, and reduces the accidental risk caused by mechanical failure or improper operation. Since the structure of the connecting rod assembly 3 is relatively simple and the components are easy to disassemble, the operation is more convenient when maintenance or replacement of components is required, and the maintenance cost is reduced.

[0024] For further information, see Figure 3 A mounting plate 15 arranged along the length direction of the slide rail 11 is fixed on the top of the carrier plate 1. The driving assembly 4 includes two sprockets 41 rotatably mounted on the mounting plate 15. An integrated chain 42 is sleeved between the two sprockets 41. A fixing block 43 is fixedly connected between one of the metal rings on the chain 42 and the connecting plate 13. A motor 44 whose output end is fixed to the rotating shaft of one of the sprockets 41 is installed on the carrier plate 1. The motor 44 drives one of the connected sprockets 41 to rotate. The rotation of the sprocket 41 drives the chain 42 to operate, so that the fixing block 43 drives the connecting plate 13 to move, ensuring the smooth unfolding and folding of the display board 2. As an efficient power transmission method, the chain 42 can ensure that the power of the motor 44 is stably and directly transmitted to the slider 12, thereby improving the operating efficiency of the entire mechanism. The design of the sprocket 41 and the chain 42 allows them to be easily disassembled and installed when maintenance or replacement is required, without the need for complex tools or techniques.

[0025] For further information, see Figure 2 and Figure 4 A card slot 21 is constructed on the side of the display board 2 facing away from the L-shaped rod 32. The design of the card slot 21 allows the display board 2 to be embedded with different types of advertising media, such as plastic, metal billboards or display screens, providing diversity and flexibility in advertising display. The internal structure of the card slot 21 ensures that the advertising medium can be stably fixed after embedding to prevent the movement or damage of the advertising content due to vibration or wind. A drag chain 22 is hinged on the bottom side of the display board 2. The setting of the drag chain 22 can thread the cables to protect the cables. At the same time, the design of the drag chain 22 enables the bottom side to be smoothly unfolded when the display board 2 is unfolded, which is easy to operate and also reduces the volume of the display board 2 when folded.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
