[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0033] As shown in Figures 1 and 2, the convertible vehicle body structure provided in this embodiment includes a chassis 1, a driver's cab 2, an equipment room 3, a convertible area 4, handrails 5, a transition piece 6, and stairs 7. One end of the chassis 1 is connected to the driver's cab 2, and the other end is connected to the equipment room 3.

[0034] An open-top area 4 is formed between the driver's cab 2 and the equipment room 3. The first side wall 41 includes a middle portion 41.1 and end portions 41.2 located at both ends of the middle portion 41.1. The upper surface of the middle portion 41.1 is lower than the upper surface of the end portions 41.2. The open-top area 4 includes the middle portion 41.1 of the first side wall 41 and an upper floor 42. The first side wall 41 is arranged on the left and right sides of the chassis 1. The end portions 41.2 at both ends of the first side wall 41 are respectively located in the driver's cab 2 and the equipment room 3. The middle portion 41.1 of the first side wall 41 is located in the open-top area 4. The upper floor 42 is located above the chassis 1. The upper floor 42 is connected to the first side walls 41 on the left and right sides. An equipment installation area 9 is formed between the upper floor 42 and the chassis 1.

[0035] The driver's cab 2 includes a front wall 21, a first partition wall 22, a first roof 23, and a second side wall 24. The front wall 21 and the first partition wall 22 are spaced apart from each other in front and back. The lower ends of the second side wall 24 and the front wall 21 are connected to the chassis 1, and the lower end of the first partition wall 22 is connected to the upper floor 42. A driver's cab entrance 25 is provided between the second side wall 24 and the first side wall 41. The first roof 23 is connected to the end 41.2 of the first side wall 41, the front wall 21, and the top of the second side wall 24. The edge of the first roof 23 near the second side wall 24 is arc-shaped. The first partition wall 22 is connected to the upper floor 42, forming an installation area entrance 26 between the bottom of the first partition wall 22 and the chassis 1, which communicates with the equipment installation area 9. This allows construction personnel to enter the equipment installation area 9 through the installation area entrance 26 to perform equipment maintenance. The first roof 23 is connected to both the first side wall 41 and the second side wall 24, helping to increase the rigidity of the driver's cab 2.

[0036] The equipment room 3 includes a rear wall 31, a third side wall 32, a second partition wall 33, and a second roof 34. The rear wall 31 and the second partition wall 33 are spaced apart from each other in front and back. The lower ends of the third side wall 32, the second partition wall 33, and the rear wall 31 are connected to the chassis 1. A passenger door 35 is provided between the third side wall 33 and the first side wall 41. The second roof 34 is connected to the end 41.2 of the first side wall 41, the rear wall 31, and the top of the third side wall 32. A partition door 36 is provided on the second partition wall 33. The second partition wall 33 is located near the convertible area 4. The passenger door 35, the partition door 36 of the equipment room 3, and the convertible area 4 are connected, forming an aisle for passengers to enter and exit.

[0037] As shown in FIG3 , the middle portion 41.1 of the first side wall 41 has no top cover at its upper end. To avoid deformation during operation, the first side walls 41 on the left and right sides are connected not only through the base frame 1 but also with an upper floor 42 provided at a certain height from the base frame 1 to connect to the first side walls 41 , so as to enhance the rigidity of the convertible area 4.

[0038] Because the upper floor 42 is elevated relative to the underframe 1, the equipment installation area 9 formed between the two can be used for wiring, piping, and installing small devices. The height of the upper floor 42 must be designed to ensure sufficient space for the equipment installation area 9 below the upper floor 42 and sufficient space for passenger movement above the upper floor 42.

[0039] As shown in Figures 3 and 5, a handrail 5 is provided on the upper surface of the first side wall 41. The height of the handrail 5 needs to take into account that the passenger's line of sight when sitting on the seat is higher than the height of the handrail 5, so that the passenger has a better view. The upper passenger activity space formed at the upper end of the upper floor 42 mainly considers that the height of the passenger standing in the later stage should be lower than the height of the power rail to ensure a safe distance. If pantograph power supply is not required, the height of the upper floor 42 can be appropriately increased to expand the space of the equipment installation area 9. The convertible area 4 can provide passengers with a wider field of vision, eliminate the sense of oppression in the car, and bring passengers a new sightseeing experience.

[0040] As shown in Figure 4, the transition piece 6 includes an arcuate surface 61, a first flat surface 62 connected to one end of the arcuate surface 61, a second flat surface 63 connected to the other end of the arcuate surface 61, and end surfaces 64 provided on either side of the arcuate surface 61. The first flat surface 62 is connected to the end portion 41.2 of the first side wall 41. The second flat surface 63 is connected to the upper surface of the middle portion 41.1 of the first side wall 41. The end surfaces 64 are connected to the side surfaces of both the middle portion 41.1 and the end portion 41.2.

[0041] A staircase 7 is provided between the upper floor 42 and the underframe 1. The staircase 7 is provided near the equipment room 3, and a partition door 36 is provided on one side of the equipment room 3 facing the staircase 7. In case of rain, passengers can enter the equipment room 3 from the convertible area 4 to avoid the rain.

[0042] As shown in FIG6 , the present invention further provides an open-top rail vehicle, comprising a bogie 8 and at least one of the above-mentioned open-top vehicle body structures disposed on the bogie 8 .

[0043] In the first embodiment, there are two convertible body structures, and the equipment rooms 3 of the two convertible body structures are connected by a connecting passage 10. Preferably, a passenger compartment door 35 is provided in only one of the equipment compartments 3. Passengers can enter the convertible area 4 of either of the two convertible body structures through the passenger compartment door 35.

[0044] In a second embodiment, there are two convertible body structures, located at the front and rear ends of the rail vehicle. At least one intermediate body structure is connected between the two convertible body structures. The intermediate body structure includes an convertible area 4 and equipment rooms 3 located at both ends of the convertible area 4. When there is only one intermediate body structure, the equipment room 3 at one end of the intermediate body structure is connected to the equipment room 3 of the convertible body structure at the rear end via a connecting passage 10, and the equipment room 3 at the other end of the intermediate body structure is connected to the driver's cab 2 of the convertible body structure at the front end. When there are multiple intermediate body structures, the intermediate body structures adjacent to the convertible body structure are connected in the same manner as above. The equipment rooms of the multiple connected intermediate body structures are connected in sequence, and only one of the connected equipment rooms is equipped with a passenger compartment door 35. The two equipment rooms are connected via a connecting passage 10.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
