Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please see Figure 1-3 A rotating structure for a bus seat display screen includes a seat body 1, a headrest 2, and a display screen body 5. Two insertion rods 3 are fixedly installed at the bottom of the headrest 2, and two insertion slots 4 are opened at the top of the seat body 1. A connecting mechanism 6 is provided between the seat body 1 and the headrest 2. A damping bearing 7 is provided on the side of the connecting mechanism 6, and a connecting rod 8 is installed on the damping bearing 7. One end of the connecting rod 8 is provided with an installation mechanism 9. During installation, the connecting mechanism 6 is installed on the surface of the insertion rod 3, and then the insertion rod 3 is inserted into the insertion slot 4. Finally, the display screen body 5 is installed on the installation mechanism 9 to complete the fixation. The damping bearing 7 enables the display screen body 5 to rotate at multiple angles. It can be manually adjusted without tools and can be stably stopped at any angle to meet the viewing needs of different passengers.

[0021] The connecting mechanism 6 includes a connecting plate 61. The top of the connecting plate 61 is provided with a positioning groove 62 at the position of the two connecting mechanisms 6. A mounting base 63 is fixedly connected to one side of the positioning groove 62. The connecting plate 61 can be fitted onto the surface of the insertion rod 3 by passing it through the positioning groove 62.

[0022] It should also be noted that the damping coefficient of the damping bearing 7 is set to 5 to 8 N·m, which can ensure that passengers can easily rotate the display screen and keep the seat body 1 stable at any angle, avoiding angle deviation caused by vehicle bumps.

[0023] Furthermore, the outer ring of the damping bearing 7 is embedded in one side of the mounting base 63, and the inner ring of the damping bearing 7 is fixedly sleeved on the surface of the connecting rod 8; by moving the connecting rod 8, the connecting rod 8 can drive the damping bearing 7 to make all-round adjustments, and thus rotate at multiple angles.

[0024] Furthermore, the mounting mechanism 9 includes a U-shaped plate 91 fixedly connected to one end of the connecting rod 8. Two slot plates 92 are equidistantly arranged on the inner wall of the U-shaped plate 91. Four sliding grooves 93 are opened on the side of the U-shaped plate 91, and an adjustment component 94 is provided inside each of the four sliding grooves 93. By locking the display body 5 into the grooves on the side of the two slot plates 92, the two slot plates 92 can be driven to move synchronously towards each other through the sliding grooves 93 and the adjustment components 94, thereby fixing the display body 5.

[0025] The adjusting component 94 includes two linkage blocks 941 and two sliders 942 that are slidably sleeved on the inner walls of the four slide grooves 93. Connecting plates 943 are fixedly connected between the two linkage blocks 941 and between the two sliders 942. The sides of the two linkage blocks 941 are threaded with bidirectional screws 944, and the sides of the two sliders 942 are slidably sleeved with guide rods 945. Both ends of the bidirectional screws 944 pass through the outer side of the U-shaped plate 91, and the bidirectional screws 944 and the U-shaped plate 91 are rotatably connected. Both ends of the guide rods 945 are fixedly connected to the inner walls of the slide grooves 93.

[0026] Specifically, by rotating the bidirectional screw 944, the two linkage blocks 941 threaded with the bidirectional screw 944 can move synchronously towards each other in the two slide grooves 93, thereby driving the two slot plates 92 to move synchronously towards each other. At the same time, under the connection of the connecting plate 943, the two sliders 942 can slide on the surface of the two guide rods 945, thereby increasing the stability of the two slot plates 92 when moving, thus achieving the fixation of the display screen body 5.

[0027] It should also be noted that the top of the slot plate 92 is fixedly connected to two reinforcing plates 95, and the top of the U-shaped plate 91 is provided with multiple reinforcing grooves 96. Reinforcing bolts 97 are threaded onto the reinforcing plates 95. When the slot plate 92 moves, it will drive the reinforcing plates 95 to move synchronously. After the display body 5 is fixed, the reinforcing bolts 97 are inserted into the reinforcing grooves 96 through the reinforcing plates 95 to fix the slot plate 92, thereby increasing the stability of the display body 5 after installation.

[0028] Furthermore, two reinforcing plates 10 are fixedly connected at the connection between the U-shaped plate 91 and the connecting rod 8, and reinforcing bolts 11 are installed between the connecting rod 8 and the two reinforcing plates 10; by setting the reinforcing plates 10 and reinforcing bolts 11, the stability of the connection between the U-shaped plate 91 and the connecting rod 8 can be increased.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
