The dynamic map display screen that displays the stop information of the operating line, the passenger compartment speaker, and the smoke / temperature / heat smoke detector are all arranged and installed on the side top panels, so the side top panels need to have sufficient strength and rigidity. The side top panels are made of aluminum profiles. One side top panel is hung on the hinge and the other side is fixed to the side wall profile with a compression lock. It has an arc structure and the front side is visible, which requires smoothness and beauty. In addition, the side top panels are equipped with air springs or support rods, which have lightweight design requirements, so that it is convenient to flip open and support the side top panels when inspecting door mechanisms and electrical equipment.

[0003] However, the general side top plates now are only provided with transverse slide grooves as reinforcement ribs, and no longitudinal reinforcement ribs are provided. The strength and rigidity of the overall side top plate are not ideal, and the entire side top plate is assembled from at least three profiles, and no reinforcement ribs are provided at the assembly point. The overall strength is not high and there are too many welds, which is not very beautiful. Utility Model Content

[0031] Example: Figure 1-4 , a side top plate with a reinforcing rib structure, comprising a side top plate body and reinforcing ribs.

[0032] The main body of the side top plate is an extruded aluminum profile, made of 6063-T5. Since the cross-section of the profile is too high and too large, reaching 638mm*262mm, in order to ensure that the profile straightness, twisting degree, contour degree, etc. meet the use requirements after extrusion, the main body of the side top plate is divided into two sections: the upper body 1 of the side top plate and the lower body 2 of the side top plate. The side top plate body 1 and the lower body 2 of the side top plate are separately opened with extrusion profile dies to extrude the profile.

[0033] The lower end of the main body 1 on the side top plate and the upper end of the lower main body 2 of the side top plate are welded together by stir friction welding, and a step 3 is provided at the welding position, and the step 3 has a height of 1 mm and a width of 10 mm.

[0034] The thickness of the upper body 1 and the lower body 2 of the side top plate are both 3mm, and the thickness of the friction stir welding joint is 4mm. The setting of the step 3 can ensure the welding quality of the side top plate body on the one hand, and improve the strength of the side top plate after welding on the other hand.

[0035] A transverse upper slide groove 4 is provided on the back of the main body 1 on the side top plate, and a transverse lower slide groove 5 is provided on the back of the main body 2 under the side top plate. The upper slide groove 4 and the lower slide groove 5 are not completely milled away, leaving a 2mm excess height, which can meet the lightweight requirements while being able to install display screens, speakers and other equipment.

[0036] Two transverse reinforcing ribs 6 are arranged on the back of the lower body 2 of the side top plate to increase the overall strength of the side top plate.

[0037] An end reinforcement rib 7 is provided at both left and right ends of the back of the welded side top plate body, and a middle reinforcement rib 8 is provided at the middle position of the back.

[0038] The end reinforcement rib 7 is made of 5083-O aluminum alloy, has good welding performance, is 3 mm thick and 10 mm high. The shape of the end reinforcement rib 7 matches the shape of the corresponding part on the side top plate body.

[0039] The end reinforcement ribs 7 are longitudinally arranged on the front and rear sides of the back of the side top plate body, 10 mm away from the end, to improve the longitudinal and end strength of the side top plate body and ensure the shape consistency of the side top plate product.

[0040] Two middle reinforcing ribs 8 are provided, and are respectively arranged in the middle of the back of the side top plate body in a longitudinal manner.

[0041] The middle reinforcing rib 8 is also made of 5083-O aluminum alloy with a thickness of 3mm. According to the size of the door mechanism parts inside the side top plate body, the upper height of the middle reinforcing rib 8 is set to 40mm and the lower height is 20mm. The shape matches the shape of the corresponding part on the side top plate body. Two middle reinforcing ribs 8 are welded in the middle of the side top plate body, on both sides of the display opening, corresponding to the clamping lock position, to improve the longitudinal and middle overall strength of the side top plate.

[0042] Corresponding avoidance notches 9 are provided on the end reinforcement ribs 7 and the middle reinforcement ribs 8 at positions corresponding to the upper slide groove 4, lower slide groove 5 and step 3 on the back of the side top plate body, for avoiding the upper slide groove 4, lower slide groove 5 and step 3 processed on the side top plate body.

[0043] During operation, the two profiles of the upper body 1 of the side top plate and the lower body 2 of the side top plate are extruded separately and welded together by stir friction welding. A step 3 with a height of 1 mm and a width of 10 mm is provided at the welding part of the side top plate body, which can increase the strength of the welding part of the side top plate body. The upper slide groove 4 and the lower slide groove 5 provided on the back of the side top plate body are not completely milled off, and a residual height of 2 mm is retained, so that the lightweight requirements can be met while being able to install display screens, speakers and other equipment. Subsequently, the end reinforcement ribs 7 and the middle reinforcement ribs 8 are welded to the back of the side top plate body in a longitudinal form. The avoidance notches 9 on the end reinforcement ribs 7 and the middle reinforcement ribs 8 correspond to the upper slide groove 4, the lower slide groove 5 and the step 3 on the side top plate, respectively.
