The invention discloses a seat rotating stand of a high-speed train, comprising a basic frame, a center revolving plate, a center support and a middle handrail, wherein the center revolving plate is fixedly connected in the basic frame, and the center revolving plate is provided with a rotation hole; and the lower end of the center support is fixedly connected on the basic frame, the upper end of the center support is connected with the middle handrail, the basic frame is a rectangular frame surrounded by a left side frame, a right side frame, a front sleeve pipe and a back sleeve pipe, and the basic frame and the middle handrail are both made from magnesium alloy materials. The invention reduces the weight by adopting light materials and ensures the mechanical strength of a product by adopting reasonable structural design and using steel materials at key load-bearing parts and abrasion parts. The running requirement of the high-speed train with the speed per hour of more than 300km / h can be met, the weight reduction effect is obvious, and the riding comfort is improved.
Description
technical field [0001] The invention relates to a seat swivel frame, in particular to a lightweight seat swivel frame which is suitable for high-speed trains and can realize the overall 180-degree turn of the seat. Background technique [0002] High-speed trains need new seats to meet the safety and comfort requirements of passengers. Most of the existing train seats are fixed chair seats with soft and hard seats, and the orientation of the seats cannot be adjusted according to the running direction of the high-speed train. When the high-speed train turns around, it may cause physical discomfort and vomiting of passengers. symptom. [0003] A steerable seat generally includes a seat base and a seat swivel frame, the seat base is fixedly mounted, and the seat swivel frame is rotatable relative to the seat base. The backrest, armrest and cushion etc. that constitute the seat are all connected on the seat swivel frame. In order to ensure safety, most of the existing train se...
