Technical Field
[0001] This utility model relates to the field of automotive table technology, and in particular to a linkage folding structure for an automotive table. Background Technology
[0002] As living standards improve, people have higher and higher requirements for the comfort of cars. Especially when the journey is long, people often eat, drink, read, and use computers in the car. Therefore, existing cars will have tables on the back of the seats to place food, water cups, books, computers and other items.
[0003] Currently, as an important accessory to improve passenger comfort, the design of the folding structure of car tray tables is crucial. Traditional car tray tables often use complex mechanical structures to reduce interference between the tray table and the supporting structure when it is opened. Although this type of design can achieve basic functions, its complex structure results in a large space occupation in the car, affecting passenger comfort. Utility Model Content
[0004] The purpose of this utility model is to provide a linkage folding structure for a car table, which can realize the folding of the car table, reduce the space occupied in the car, and improve passenger comfort.
[0005] To achieve the above objectives, this utility model provides a linkage folding structure for an automobile table, including a table and two linkage folding assemblies. The two linkage folding assemblies are respectively located on the side of the table. Each linkage folding assembly includes a mounting bracket, a first pin, a first rotating arm, a second pin, a second rotating arm, a connecting shaft, an eccentric wheel, an eccentric shaft, an eccentric rod, and a connecting rod.
[0006] The mounting bracket is fixedly connected to the inner side of the tabletop; the first pin is rotatably mounted on the mounting bracket; the first rotating arm is fixedly connected to the first pin and located on the side of the first pin; the second pin is rotatably mounted on the mounting bracket; the second rotating arm is fixedly connected to the second pin and located on the side of the second pin; the connecting shaft is rotatably mounted on the mounting bracket; the eccentric wheel is fixedly connected to the connecting shaft and located on the side of the connecting shaft; the eccentric shaft is fixedly connected to the eccentric wheel and located on the side of the eccentric wheel; the eccentric rod is rotatably connected to the eccentric shaft and located on the side of the eccentric shaft; one end of the connecting rod is rotatably connected to the second rotating arm, and the other end is rotatably connected to the eccentric rod and located between the second rotating arm and the eccentric rod.
[0007] The connecting rod folding assembly further includes a guide rod; the guide rod is rotatably connected to the second rotating arm and is located on the side of the second rotating arm; the second rotating arm has an arc-shaped groove on the side near the guide rod.

[0009] The second rotating arm has a second mounting hole located at the end of the second rotating arm away from the second pin.
[0010] The connecting rod folding structure of the car table also includes a stabilizing frame; the stabilizing frame is fixedly connected to the table and located inside the table, between the two mounting frames.
[0011] This utility model discloses a linkage folding structure for an automotive table. The first rotating arm, at its end furthest from the first pin, is hinged to the automotive seat frame, and the second rotating arm, at its end furthest from the second pin, is also hinged to the seat frame. This allows the table to be mounted on the seat back. The first and second rotating arms feature a special shape design.

The design of the arc groove 14 is more compact and conforms to the movement trajectory of the entire connecting rod folding assembly 2, reducing space waste and improving the smoothness of the table 1 folding. The surface of the arc groove 14 is smoothed to reduce the frictional resistance of the second rotating arm 7 during the movement and improve the folding efficiency. The eccentric wheel 9 can be driven by a motor or rotated manually, and the appropriate driving method can be selected according to actual needs.
