The lower cover plates of the traction beam and the middle beam have elongated holes for installing the brake adjuster and tie rod. The middle beam 203 also has internal stiffening plates, consisting of two vertical stiffening plates and one horizontal stiffening plate. The horizontal stiffening plate corresponds to the lower cover plate of the horizontal beam, and the vertical stiffening plate corresponds to the web plate of the horizontal beam. The vertical stiffening plates have elongated holes for installing the brake adjuster and upper tie rod.

[0106] The lower side beam 201 is made of cold-formed channel steel with a thickness of 6mm, a height of 240mm, and a width of 85mm.

[0107] The bolster beam 202 is a double-web welded structure, consisting of an upper cover plate, a web plate, and a lower cover plate. The upper cover plate of the bolster beam 202 is 7mm thick, the web plate is 10mm thick, and the lower cover plate is 12mm thick.

[0108] The bottom crossbeam 205 is a variable cross-section single-web welded structure, with stiffening plates installed between the upper and lower cover plates at the load-bearing points of the bottom crossbeam 205.

Stiffeners are installed between the sleeper beam 202, the bottom crossbeam 205, and the lower side beam 201. The floor slab 204 is laid in sections on adjacent beams. The floor slab 204 is designed with stiffeners. A top plate is installed on the lower plane of the lower side beam 201 at the position corresponding to the sleeper beam 202.

[0110] The underframe is equipped with a B+ grade cast upper center plate, and uses B+ grade cast steel impact seats and C grade cast steel front and rear trailing plate seats. The end of the center beam 203 is where the coupler buffer device is installed, directly bearing longitudinal (longitudinal) forces. The bolster beam 202 is where the underframe and bogie connect. The lower part of the bolster beam 202 has an upper side bearing and an upper center plate, which are opposite to the lower side bearing and lower center plate on the bogie bolster, respectively. It bears a large load, supporting the entire weight of the car, and transmits the weight to the running gear through the center plate.

[0111] There are multiple electrical equipment mounting brackets, including battery bracket mounting brackets 206 and auxiliary power supply equipment mounting brackets 207. The auxiliary power supply equipment mounting brackets 207 are located in the middle region of the underframe 200 along the length of the vehicle body; the battery bracket mounting brackets 206 are located at both ends of the underframe 200 along the length of the vehicle body. The battery bracket mounting brackets 206 are used to mount battery brackets 504; modular batteries within the vehicle body are arranged on the battery brackets 504.

[0112] The battery bracket mounting base 206 is made of thick plate by machining or casting, including a plate body, which is welded to the beam of the base frame; the edge of the plate body is provided with a fastener mounting groove; the fastener mounting groove has a double-layer structure, including a lower bolt head receiving groove 2062 and a bolt rod receiving groove 2061, the width and depth of the bolt rod receiving groove 2061 are smaller than those of the bolt head receiving groove 2062.

[0155] The end post 306 is a square tube end post, with its two ends respectively welded to two second corner reinforcement seats 310. The end of the first bent portion 31011, the edge of the third web plate 3102, and the plate surface of the fourth bent portion 31014 in the second corner reinforcement seat 310 at the upper end of the end post 306 are all welded to the lower surface of the upper side beam 101. The fourth web plate 3103 in the second corner reinforcement seat 310 is welded to the surface of the upper side beam 101 facing the interior of the vehicle body. The end of the first bent portion 31011, the edge of the third web plate 3102, and the plate surface of the fourth bent portion 31014 in the second corner reinforcement seat 310 at the lower end of the end post 306 are all welded to the upper surface of the lower side beam 201. The fourth web plate 3103 in the second corner reinforcement seat 310 is welded to the surface of the lower side beam 201 facing the exterior of the vehicle body.

[0156] Compared to the existing technology of directly welding or attaching the end column to the upper and lower side beams, the solution provided in this embodiment enables the power supply shed to have lower stress and longer fatigue life under full load.

[0157] In the aforementioned end wall 300, the horizontal strip 303, the column 302, and the equipment box mounting base 305 are all U-shaped channel structures, which are all welded to the side of the end plate 301 facing the interior of the vehicle body. The equipment box mounting base 305 is provided with mounting holes to facilitate the installation of square neck bolts for assembling auxiliary power supply equipment 312.

[0158] The roof 400 is divided into multiple roof sections along the length of the vehicle body. The roof sections include a high roof section 401 and a low roof section 402. The height of the low roof section 402 is lower than that of the high roof section 401.

[0159] After applying the above-mentioned roof 400, if the power supply shed needs to be equipped with equipment such as air conditioner 503, the components of the equipment that need to be arranged outside the vehicle body can be installed on the low roof section 402 of the roof 400 to prevent the components from protruding too much relative to the entire roof 400. Compared with the existing technology, which directly installs the components that need to be arranged outside the vehicle body on the roof or side wall with a regular outer contour, it can reduce the wind resistance of the components outside the vehicle body, thereby reducing or even eliminating the impact of wind resistance on the performance of the added equipment such as air conditioner 503.

[0160] In some embodiments, the low roof section 402 of the roof 400 is provided as one. Correspondingly, the high roof section 401 may be provided as one, or two, with the two high roof sections 401 located on either side of the low roof section 402 along the length of the power supply shed, such as... Figure 44 , 45 As shown.

[0161] In some embodiments, the vehicle body 100 has multiple low roof sections 402, and a high roof section 401 is provided between any two adjacent low roof sections 402.

[0162] In the aforementioned roof 400, among all the roof segments, the two roof segments at both ends along the length of the vehicle body are preferably set as high roof segments 401. In this case, the roof 400 is divided into at least three roof segments along the length of the vehicle body, and the number of high roof segments 401 is one more than the number of low roof segments 402, with high roof segments 401 and low roof segments 402 alternating. This arrangement ensures that high roof segments 401 are arranged on both sides of any low roof segment 402 along the length of the vehicle body, so that the two sides of the low roof segment 402 are protected by different high roof segments 401, thus preventing excessive wind resistance at the low roof segment 402.

[0163] Of course, the two roof sections at both ends along the length of the vehicle body can also be configured as either one low roof section 402 or both low roof sections 402. In this case, by selecting a car of appropriate height as the adjacent car of the power supply shed, the low roof section 402 located at the end of the power supply shed along the length of the vehicle can be protected by the adjacent car, thus avoiding the situation where the low roof section 402 at the end of the power supply shed has excessive wind resistance.

[0164] The low roof section 402 includes a crossbeam 424, a first roof panel 425, and an equipment mounting base 422; there are multiple crossbeams 424, which are spaced apart; the first roof panel 425 is laid on top of the crossbeams 424 and is fixedly connected to the crossbeams 424; the equipment mounting base 422 is arranged on top of the first roof panel 425, and the equipment mounting base 422 is fixedly connected to the crossbeams 424 and / or the first roof panel 425.

[0168] In all the crossbeams 424 of the low roof section 402, any two adjacent crossbeams 424 can be provided with only a first roof panel 425. The first roof panel 425 can completely close the gap between the two adjacent crossbeams 424, or only close part of the gap between the two adjacent crossbeams 424, so that the exposed gap can be used to arrange the wiring of the added air conditioner 503 and other equipment.

[0169] In all the crossbeams 424 of the low roof section 402, multiple first roof panels 425 can be laid between any two adjacent crossbeams 424. These multiple first roof panels 425 can be spliced ​​together in sequence to completely close the gap between the two adjacent crossbeams 424, or only close part of the gap between the two adjacent crossbeams 424, so that the exposed gap can be used to arrange the wiring of the added air conditioner 503 and other equipment.

[0170] This embodiment does not limit the number of first roof panels 425 between any two adjacent crossbeams 424, nor whether all the first roof panels 425 between any two adjacent crossbeams 424 completely close the gap between the two adjacent crossbeams 424. They can be arranged according to actual needs.

[0171] In the aforementioned roof 400, the high roof section 401 includes a roof curved beam 412 and a second roof panel 411; there are multiple roof curved beams 412, which are spaced apart; the second roof panel 411 is laid above or below the roof curved beams 412, and the second roof panel 411 is fixedly connected to the roof curved beams 412.

[0172] Both ends of the roof curved beam 412 are fixed to the upper side beams 101 of the two side walls 100, respectively. A first roof panel 411 can be provided in the high roof section 401, and this first roof panel 411 is laid on all the roof curved beams 412 of the high roof section 401. Multiple first roof panels 411 can be provided in the high roof section 401, wherein any first roof section 411 can be laid between two adjacent roof curved beams 412, or laid on three or more roof curved beams 412 arranged sequentially; this embodiment does not impose any limitation.

[0173] In the aforementioned roof 400, any adjacent first roof panel 425 and second roof panel 411 are fixedly connected by a sealing plate 421, and the sealing plate 421 seals the gap between the adjacent first roof panel 425 and second roof panel 411.

[0174] To improve the installation reliability of the sealing plate 421, a vertical rod 423 is fixed to the side of the sealing plate 421 facing the interior of the vehicle body, and the lower end of the vertical rod 423 is fixed to the crossbeam 424.
