[0018] Hereinafter, embodiments of the present utility model will be described with reference to the accompanying drawings. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and do not constitute a limitation of the utility model.

[0020] The utility model provides a subway vehicle seat armrest, the structure of which is as follows: Figure 1 As shown, it includes a first handrail 1, a second handrail 2, a four-way connector 3 and a connecting end 4. The first handrail 1 is welded with connecting ends 4 at both ends, which are used to fix the first handrail 1 to the inner wall of the subway car and the side wall of the subway seat. The second handrail 2 is a U-shaped curved pipe structure, and the two ends of the second handrail 2 are fixedly connected to the side wall of the subway seat, and the middle part of the second handrail 2 is fixedly connected to the first handrail 1 through the four-way connector 3.

[0021] In a preferred embodiment, the first handrail 1 is a stainless steel arc bent pipe structure, and the two ends of the first handrail 1 are respectively welded to the stainless steel connecting end 4, and its structure is as follows: Figure 2 As shown. The arc shape is ensured to be accurate through angle template control, and the overall brushing treatment is performed after welding to ensure the appearance of the handrail. One end of the first handrail rod 1 is connected to the side wall of the subway car, and the other end is connected to the side wall of the seat.

[0022] In a preferred embodiment, the second handrail 2 is a stainless steel U-shaped curved pipe structure, and stainless steel semi-mounting seats 5 are welded to both ends of the second handrail 2. Figure 3 The second handrail 2 is controlled by the angle template to ensure the arc is accurate. The angle template detection control of the bend pipe is as follows: Figure 4 After welding, the whole is brushed to ensure the appearance of the handrail. During welding, welding tooling is used to position the end and the semi-mounting seat accurately. After welding, the whole is inspected by tooling to ensure the installation performance of the handrail. The welding tooling is as follows: Figure 5 The second handrail 2 is fixedly connected to the subway seat through the semi-mounting seat 5. The semi-mounting seat 5 adopts a split-half connection structure. By adjusting the split-half position gap, the second handrail is fitted with the subway stand cover and the seat connection. Figure 6 As shown, when the seat armrest assembly is installed, by adjusting the gap at the semi-mounting seat 5, it can be ensured that the seat armrest fits tightly with the connection between the vertical cover plate and the seat, thereby ensuring the installation performance of the seat armrest.

[0023] The seat armrest provided by the embodiment of the utility model eliminates the large-area windshield structure, uses a stainless steel round tube bend, and then welds it with the stainless steel casting of the connecting end, which is convenient for passengers to lean on, and adds a second handrail rod for holding in the original windshield area, which is convenient for the gripping needs of standing passengers in the door area to avoid safety hazards. The mounting seat of the second handrail rod adopts a half-connection structure. By adjusting the half-position gap during installation, the second handrail rod can be closely fitted with the vertical cover plate and the seat connection, which solves the problem of poor appearance caused by the difficulty of installing the handrail. It has the advantages of convenient installation, low cost, short production period and strong safety. In the production process, the handrail is bent by a CNC pipe bending machine, and a one-to-one angle template is used for detection after bending to ensure that the bending angle meets the requirements. When the handrail is assembled and welded as a whole, the assembly welding tool is used for positioning to ensure that the position of the seat armrest connecting end is accurate. During the welding process, a quick clamp is used to press and reduce the welding deformation. After the welding is completed, the tool is put into the tool for detection again, and it is fine-tuned, and finally a simulated installation is performed to ensure that the product quality of the seat armrest meets the requirements.
