[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] An embodiment of the present invention discloses a roof flow guiding device, as shown in the attached Figure 1 drawing, which includes a top flow guiding cover 1, two side flow guiding covers 2 and an end flow guiding cover 3. The top flow guiding cover 1 is arranged directly above the vehicle roof panel 4. The two side flow guiding covers 2 are respectively fixed on both sides of the top flow guiding cover 1. The side flow guiding covers 2 are inclined and transitionally connected between the top flow guiding cover 1 and the vehicle body side wall. The end flow guiding cover 3 is fixed at the ends of both the top flow guiding cover 1 and the side flow guiding covers 2.

[0049] As a preferred embodiment, considering that the top flow guiding cover 1 is segmented corresponding to different equipment, the top flow guiding cover 1 adopts a segmented structure to adaptively adjust the structure of the top flow guiding cover 1, reduce the processing and assembly difficulty of the top flow guiding cover 1, and is beneficial to reducing the production cost. One end of both the top flow guiding cover 1 and the side flow guiding covers 2 abuts against the rear wall of the driver's cab, and the other end of both is connected to the end flow guiding cover 3. The cross section of the end flow guiding cover 3 is an isosceles trapezoid.

[0050] The top flow guiding cover 1, the two side flow guiding covers 2 and the end flow guiding cover 3 are all made of glassy carbon composite material, which is lighter in mass than traditional materials such as metal and fiberglass, meets the lightweight design requirements, and has higher strength, reducing the maintenance frequency.

[0051] The top flow guiding cover 1, the two side flow guiding covers 2 and the end flow guiding cover 3 enclose a full-coverage flow guiding structure. The full-coverage flow guiding structure completely covers the vehicle roof panel 4, optimizes the aerodynamic shape of the roof, avoids causing large wind resistance, and effectively improves the aerodynamic performance.

[0052] To reduce the wind resistance of the top flow guiding cover 1, as shown in the attached Figure 3As shown in the figure, the top fairing 1 includes a top flat cover plate and two top inclined plates. The top flat cover plate is parallel to the vehicle roof plate 4. The two top inclined plates are integrally and obliquely arranged on both sides of the top flat cover plate respectively. The top flat cover plate and the top inclined plates are smoothly connected by arc plates. The surfaces of the two top inclined plates form top inclined surfaces 11, and the surfaces of the two side fairings 2 respectively and symmetrically form side inclined surfaces 21. The inclination angle of the side inclined surface 21 is the same as that of the top inclined surface 11, ensuring that the side inclined surface 21 and the top inclined surface 11 are coplanar, so that the connection between the top fairing 1 and the side fairings 2 can maintain a good aerodynamic shape, which is beneficial to improving the aerodynamic performance.

[0053] In addition, as shown in the Figure 3 figure, the connection between the side fairing 2 and the vehicle body side wall is smoothly connected to form an ideal streamline shape, optimizing the dynamic shape of the vehicle body 9, reducing the running resistance of the vehicle body 9, and improving the aerodynamic performance.

[0054] As shown in the Figure 2 and 3 figure, the vehicle roof plate 4 is fixedly provided with a side mounting seat 5. The side mounting seat 5 is integrally extruded and formed by aluminum alloy profiles. The side mounting seat 5 is in an L shape and includes a horizontal support section 51 and a vertical support section 52 that are integrally and vertically connected. The horizontal support section 51 extends along the transverse direction of the vehicle body 9, and the vertical support section 52 extends along the vertical direction of the vehicle body 9. In this text, the transverse direction of the vehicle body refers to the direction parallel to the width direction of the vehicle body 9, and the vertical direction in this text refers to the direction parallel to the height direction of the vehicle body 9. The horizontal support section 51 is fixedly connected to the vehicle roof plate 4. The vehicle roof plate 4 forms an installation chute. Stopping edges are respectively formed on two opposite sides of the chute edge of the installation chute. A T-shaped bolt is installed in the installation chute. The head of the T-shaped bolt abuts against the stopping edge. The T-shaped bolt passes through the horizontal support section 51, and a T-shaped nut is arranged at the tail of the T-shaped bolt, so that the side mounting seat 5 is detachably fixed on the vehicle roof plate 4, and the fixed position of the side mounting seat 5 is adjusted by adjusting the relative position of the T-shaped bolt in the installation chute, meeting the requirements of quick disassembly and assembly by one person and improving the maintenance efficiency. The top of each side fairing 2 is bent to form a side upward flange 22, and the side upward flange 22 is fixedly connected to the vertical support section 52. A fixing bolt passes through the side upward flange 22, and a T-shaped nut is installed at the tail of the fixing bolt, so that one side of the side fairing 2 is detachably fixed to the side mounting seat 5.

[0055] As shown in the Figure 3 figure, the bottom of each side fairing 2 is bent to form a side downward flange 23, and the side downward flange 23 is fixedly connected to the horizontal support section 51, ensuring that the side fairing 2 is obliquely arranged, so that the side fairing 2 is smoothly connected to the vehicle body side wall, and also ensuring that the connection between the side fairing 2 and the vehicle body side wall has good sealing performance.

[0056] As shown in the Figure 3 and4 As shown, the side lower flange 23 is riveted with a transition connecting plate 24, the transition connecting plate 24 is L-shaped, and the transition connecting plate 24 is bent and provided with a clamping tooth 241. Figure 3 and 5 As shown, a clamping groove 53 is formed on the side of the horizontal support section 51, and the clamping teeth 241 are clamped and matched with the clamping groove 53 along the transverse direction of the vehicle body 9. The side fairing 2 is installed in the form of bolting or plugging, which is convenient for rapid disassembly, overhaul and maintenance, improves the overhaul efficiency, and also reduces the heat input of rapid welding, reduces the difficulty of roof manufacturing, reduces the risk of deformation of the vehicle body 9, and improves the processing accuracy of the vehicle body 9.

[0057] As attached Figure 3 As shown, a wiring channel 6 is formed between the side mounting seat 5 and the side air deflector 2 for routing the cables and wires on the roof, so that the cables and wires are hidden between the side air deflector 2 and the top air deflector 1, avoiding the cables and wires from being exposed and damaged by friction, and also avoiding the cables and wires from being interrupted by signals or short-circuited due to water immersion, which can not only make the vehicle body 9 more compact, but also extend the service life of the cables and wires, reduce the failure rate of the whole vehicle, and improve the reliability of the whole vehicle.

[0058] A plurality of fixing through holes are provided on the side of the side mounting seat 5 facing the wiring channel 6, and wire ties are passed through the fixing through holes. The wire ties are used to bind the cables and cables passing through the wiring channel 6 to ensure that the cables and cables are reliably fixed and to avoid malfunctions of the cables and cables due to severe shaking.

[0059] As attached Figure 12 and 13 As shown, the side air guide 2 includes a grille air guide 25 with a plurality of ventilation grilles. The ventilation grilles are opposite to the air inlet of the equipment to meet the ventilation and heat dissipation requirements of the equipment. In addition, the grille shape of the grille air guide 25 is aerodynamically optimized to effectively reduce wind noise under large ventilation requirements. The grille air guide 25 is formed by integrally stamping and bending a stainless steel plate. The surface of the grille air guide 25 is coated with a composite material layer and is flush with other side air guides 2. As shown in the attached Figure 13 As shown, a plurality of side reinforcements 251 are fixedly provided on the side of the grille air deflector 25 facing the roof panel 4. The side reinforcements 251 are L-shaped and are fixed to the middle section on the inner side of the grille air deflector 25 by welding, so as to enhance the strength of the grille air deflector 25 so as to meet the impact vibration load when the train runs at high speed.

[0060] As attached Figure 3As shown in the figure, L-shaped connecting plates 12 are symmetrically formed on both sides of the top fairing 1. The L-shaped connecting plates 12 and the top inclined plate are arranged at an angle and integrally connected. The L-shaped connecting plates 12 are parallel and opposite to the vertical support sections 52 of the side mounting seats 5. The vehicle roof panel 4 is fixedly provided with top fixing seats 41, and the L-shaped connecting plates 12 abut against the top fixing seats 41. A T-shaped sliding groove is formed in the top fixing seat 41, and a T-shaped bolt is inserted into the T-shaped sliding groove. The T-shaped bolt is fixedly connected to the L-shaped connecting plate 12, and a locking nut is arranged at the tail of the T-shaped bolt, so that both sides of the top fairing 1 are detachably fixed on the top fixing seat 41 by means of the T-shaped bolt. An adjusting sliding groove is provided in the top fixing seat 41, and the T-shaped bolt is slidably installed in the adjusting sliding groove. The fixing position of the top fairing 1 on the top fixing seat 41 is adjusted by adjusting the T-shaped bolt. A reinforcing rib is formed on the inner side of the top fairing 1 to improve the strength of the top fairing 1 and meet the requirement of people standing on the top of the top fairing 1.

[0061] A weight reduction hole 13 is provided on the side of the L-shaped connecting plate 12 to reduce the weight of the top fairing 1 and facilitate the realization of lightweight. In addition, the weight reduction hole 13 can also replace the wire routing hole for wire routing, making full use of the space between the top fairing 1 and the vehicle roof panel 4, eliminating the need for an additional wire routing hole, with a simpler structure and more convenient processing.

[0062] As shown in the attached Figures 6 to 8 As shown in the figure, the vehicle roof panel 4 is fixedly provided with a top support seat 42, and the top fairing 1 is fixedly connected to the top support seat 42, so that the top support seat 42 provides support for the top fairing 1 in the vertical direction, increasing the stability of the top fairing 1. The top fairing 1 and the top support seat 42 are preferably bolt-connected. The upper surfaces of the top fairing 1 and the top support seat 42 are flush, and an antenna interface 420 is collectively provided on the upper surface of the top support seat 42. The antenna interface 420 is used to fix the antenna. The antenna interface 420 is collectively provided on the top support seat 42, eliminating the need for an additional antenna interface 420 and making the structure more compact.

[0063] As a preferred embodiment, as shown in the attached Figure 7 As shown in the figure, the top support seat 42 includes an upper connecting plate 421, a lower connecting plate 422, and two vertical support frames 423 fixedly connected in parallel between the upper connecting plate 421 and the lower connecting plate 422. The lower connecting plate 422 is fixedly connected to the vehicle roof panel 4. The upper connecting plate 421 is parallel to the lower connecting plate 422, and the upper connecting plate 421 is fixedly connected to the top fairing 1. A wire routing rack 424 is formed in the vertical support frame 423 to support the cables laid on the vehicle roof panel 4. The wire routing rack 424 can specifically be a C-shaped structure for restricting the position of the cables. The wire routing rack 424 is fixed in the vertical support frame 423 by welding, but is not limited thereto.

[0064] Reinforcing rib plates 425 are provided between the upper connecting plate 421 and the vertical support frame 423 and between the lower connecting plate 422 and the vertical support frame 423; the vertical support frame 423 includes two parallel vertical support plates, and reinforcing edges 426 are formed by bending the opposite side edges of the two vertical support plates; both the reinforcing rib plates 425 and the reinforcing edges 426 can enhance the strength of the top support seat 42, provide stable support for the top fairing 1, and enable the top fairing 1 to withstand the impact and vibration loads generated during the high-speed operation of the train.

[0065] As shown in the Figure 9 appendix 10 and

[0066] shown, a plurality of end mounting seats 7 are fixedly provided on the car roof plate 4 and the side mounting seats 5. Each end mounting seat 7 is in a C shape, ensuring that the end mounting seat 7 has sufficient strength to connect the end fairing 3 and reducing the risk of the end fairing 3 being insecurely fixed. An L-shaped extension plate 71 is integrally formed on one side of each end mounting seat 7 facing the end fairing 3, and the L-shaped extension plate 71 is fixedly connected to the end fairing 3, which can not only fixedly connect the car roof plate 4 to the end fairing 3 but also fixedly connect the side mounting seat 5 to the end fairing 3, increasing the fixing points of the end fairing 3, ensuring the reliable fixation of the end fairing 3, and enhancing the impact resistance strength of the end fairing 3.

During installation, adjustment gaskets can be added between the end fairing 3 and the L-shaped adapter plate 8 or between the top fairing 1 and the L-shaped adapter plate 8. By adjusting the thickness or quantity of the gaskets, the installation positions of the end fairing 3 and the top fairing 1 can be adjusted to compensate for the machining errors of the end fairing 3 and the top fairing 1.

[0068] A drainage gap is formed between the end fairing 3 and the car body end wall, enabling the accumulated water on the car roof plate 4 to drain along the drainage gap. In addition, the end fairing 3 can also be provided with pipeline holes to meet the requirements of wire routing and pipe routing.
