[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0023] This utility model provides a chair with a folding table, such as... Figures 1-6 As shown, it includes a main body 1, a fixed bracket 2, a tabletop bracket 3, a tabletop rotation shaft 4, a tabletop 5, and a tabletop driving mechanism 6. The main body 1 has a recessed mounting cavity 11. The fixed bracket 2 is installed in the mounting cavity 11. Two tabletop brackets 3 are provided and symmetrically arranged on the fixed bracket 2. The tabletop 5 is rotatably arranged between the tabletop brackets 3 via the tabletop rotation shaft 4. The tabletop driving mechanism 6 drives the tabletop rotation shaft 4 to rotate, thereby driving the tabletop 5 to rotate, realizing the opening and closing of the tabletop 5.
[0024] In one embodiment, the tabletop driving mechanism 6 includes a first connecting rod 61, a second connecting rod 62, a first cam 63, and a first motor 64. The first motor 64 is fixedly mounted on the fixed bracket 2. One end of the first connecting rod 61 is fixedly connected to the tabletop rotation shaft 4, and the other end is rotatably connected to one end of the second connecting rod 62. The other end of the second connecting rod 62 is rotatably connected to the first cam 63. The first motor 64 drives the first cam 63 to rotate, causing the second connecting rod 62 and the second connecting rod 61 to push the tabletop rotation shaft 4 to rotate, thereby driving the tabletop 5 to rotate. It is understood that when the first motor 64 drives the first cam 63 to rotate, the connection point between the first cam 63 and the second connecting rod 62 changes position. This connection point needs to maintain a fixed distance from the connection point between the first connecting rod 61 and the second connecting rod 62 through the second connecting rod 62. Therefore, while the first cam 63 rotates, it will push the first connecting rod 61 to rotate around the tabletop rotation shaft 4 through the second connecting rod 62, thereby achieving the rotation of the tabletop 5. Preferably, an arc-shaped guide groove 31 is provided on the tabletop support 3, and a limiting pin 65 is provided on the first connecting rod 61. The limiting pin 65 is placed in the arc-shaped guide groove 31, and the rotation angle and rotation direction of the tabletop 5 are limited by the cooperation between the arc-shaped guide groove 31 and the limiting pin 65.
[0025] In one embodiment, such as Figures 1-3As shown in Figs. 7 and 8, the display mechanism is arranged inside the mounting cavity 11. In the storage state, the display mechanism is hidden behind the table board 5, improving the safety.
[0026] The display mechanism comprises a display support 71, a display rotating shaft 72, a display screen 73 and a display driving mechanism 74. The display support 71 is fixedly and symmetrically arranged inside the mounting cavity 11. The display screen 73 is rotatably arranged on the display support 71 through the display rotating shaft 72. The display driving mechanism 74 is used to drive the display screen 73 to rotate around the display rotating shaft 72. Specifically, the display driving mechanism 74 comprises a second motor 741, a third connecting rod 742, a second cam 743 and a fixed block 744. The fixed block 744 is fixedly arranged on both sides of the display screen 73. One end of the third connecting rod 742 is rotatably connected with the fixed block 744, and the other end is rotatably connected with the second cam 743. The second motor 741 is used to drive the second cam 743 to rotate, so that the third connecting rod 742 pulls the display screen 73 to rotate. It can be understood that the second motor 741 drives the second cam 743 to rotate, the position of the connecting point of the third connecting rod 742 and the second cam 743 changes, and the distance between the connecting point of the third connecting rod 742 and the fixed block 744 and the connecting point of the third connecting rod 742 and the second cam 743 remains unchanged due to the action of the third connecting rod 742. Therefore, the third connecting rod 742 pulls the display screen 73 to rotate, thereby realizing the unfolding and storage of the display screen 73.
[0027] In an embodiment, the mounting cavity 11 is arranged at the upper part of the body 1.
[0028] The above is only the preferred embodiment of the present application, and is not used to limit the implementation scope of the present application. If the present application is modified or replaced equivalently without departing from the spirit and scope of the present application, it should be covered in the protection scope of the present application.
