The invention discloses an extension type table for a bullet train, and relates to the field of transportation. The extension type table comprises an outer table, a motor is arranged in the outer table; an output shaft of the motor is sequentially connected with a first driving bevel gear and a second driving bevel gear; the first driving bevel gear is in engaged transmission with a first driven bevel gear; the first driven bevel gear is fixedly connected with a first lead screw, the first lead screw is in threaded connection with a first sliding block, the first sliding block is rotationallyconnected with a push rod, the other end of the push rod is connected with a fixing block, the fixing block is arranged on the abutting rod, and the second driving bevel gear is in meshing transmission with a second driven bevel gear. The motor is in engaged transmission through two pairs of bevel gears, synchronous outward movement of the abutting rod and the inner table is achieved, and finally,the abutting rod abuts against the check block and the triangular support at the lower end of the inner table so that the stability is good; according to the device, passengers do not need to get upto vacate space, the passengers in the aisle can use the table conveniently, no extra vertical support is arranged below the table, collision of legs of the passengers is avoided, and the experience comfort degree of the passengers is greatly improved.
本发明公开了一种动车用延展型桌子,涉及交通运输领域,包括外桌,所述的外桌内部安置有电机,电机输出轴上依次连接有第一主动锥齿轮和第二主动锥齿轮,第一主动锥齿轮啮合传动有第一从动锥齿轮,第一从动锥齿轮固定连接有第一丝杆,第一丝杆上螺纹连接有第一滑块,第一滑块上转动连接有推杆,推杆另一端连接有固定块,固定块设置在抵杆上,所述的第二主动锥齿轮啮合传动有第二从动锥齿轮。电机通过两对锥齿轮啮合传动,实现抵杆和内桌同步外移,最终抵杆抵住内桌下端的挡块,三角支撑,稳定性好,该装置无需乘客起身腾出空间,也方便过道的乘客使用桌子,且桌子下方无多余立式支撑,避免乘客腿部磕碰,大大改善乘客的体验舒适度。
