According to the vehicle-mounted table plate, a back plate connecting plate is detachably arranged on the back of a vehicle seat, and two through grooves are symmetrically formed in the back plate connecting plate; one end of the four-bar linkage is rotatably arranged on one side of the back plate connecting plate close to the back of the vehicle seat; the four connecting rods comprise two upper connecting rods and two lower connecting rods, the middles of the two upper connecting rods and the middles of the two lower connecting rods are of bent structures, one ends of the two upper connecting rods and one ends of the two lower connecting rods are rotatably arranged in the two through grooves in a one-to-one correspondence mode, and the other ends of the two upper connecting rods and the other ends of the two lower connecting rods are symmetrically and rotatably arranged on the table plate; the two lower connecting rods and the two upper connecting rods are mutually limited respectively; the two first energy storage mechanisms are arranged between the two upper connecting rods and the back plate connecting plate respectively, so that the two upper connecting rods always keep the trend of being far away from the back plate connecting plate, and the table plate moves from an inclined state to a horizontal state. The invention has the characteristics of more stable movement and no rotation clamping stagnation dead point.

    本发明公开了一种车载桌板,包括:背板连接板可拆卸的设置在车辆座椅背部,且背板连接板上对称设置有两个贯通槽;四连杆一端可转动的设置在靠近车辆座椅背部的背板连接板一侧;四连杆包括:中部呈弯折结构的两个上连杆和两个下连杆,且两个上连杆和两个下连杆的一端一一对应可转动的分别设置在两个贯通槽中,两个上连杆和两个下连杆的另一端对称可转动的设置在桌板上,两个下连杆分别与两个上连杆相互限位;两个第一储能机构分别设置在两个上连杆与背板连接板之间,使两个上连杆始终保持远离背板连接板的趋势,实现了桌板从倾斜到水平的运动。本发明具有运动更平稳和无旋转卡滞死点的特点。
