[0040] Please refer to Figure 1 , Figure 3 and Figure 5 , with the continuous development of the new energy industry, more and more industries choose to use batteries with better environmental protection performance as the power source to replace traditional fuel power. For example, in the rail locomotive industry, it has changed from traditional fuel type to pure electric. Due to the limited space inside the locomotive, it is impossible to accommodate a large-capacity battery, so the vehicle's endurance is limited. In order to increase the cruising range, industry designers have added a battery car 100 at the rear end of the locomotive. The battery car 100 has a container battery 20. The battery car 100 runs on the track 200 following the locomotive, and the container battery 20 in the battery car 100 can supply power to the locomotive. However, in the traditional battery car 100, after the container battery 20 is installed, it is prone to deformation due to uneven stress, which affects the reliability and safety of the installation of the container battery 20, and the subsequent maintenance of the container battery 20 is troublesome.

[0041] Please refer to Figures 1 to 6, through in-depth research, it is found that the reason for the easy deformation of the container battery 20 is as follows: the support body 11 on the vehicle body 10 of the battery vehicle 100 that supports the container battery 20, and the container battery 20 itself has a relatively long span, and there are errors in the process dimensions of the locking member 12 and the mating member 22 between the container body 21 that fixes the container battery 20 and the support body 11. During the fixing process of the container body 21 and the support body 11, it often occurs that the bottom surface of the mating member 22 does not fully contact the support body 11, resulting in the container battery 20 still being in a suspended state. This problem will cause uneven stress on the cross beam where the mating member 22 is installed at the bottom of the container body 21. As the operation time increases, the cross beam will deform, resulting in stress on the welding points of the battery cluster support inside the container body 21, thus affecting the installation reliability and safety of the container battery 20. In addition, due to the deformation of the cross beam, the distance between the top longitudinal beam and the bottom longitudinal beam of the door on the side of the container body 21 will be different, thus affecting the opening and closing of the door and affecting the later maintenance.

[0042] It is worth mentioning that both the top longitudinal beam and the bottom longitudinal beam of the door refer to the beam structures extending along the length direction of the container body 21. To alleviate the above problems, the present application provides a battery vehicle 100, which includes a vehicle body 10, a container battery 20 and a filling component 30. The vehicle body 10 includes a support body 11 and a plurality of locking members 12. The support body 11 has a support surface 113, and all the locking members 12 protrude from the support surface 113. The container battery 20 includes a container body 21 and a plurality of mating members 22 arranged at the bottom of the container body 21. All the mating members 22 are arranged along the circumference of the container body 21, and the mating members 22 correspond to the locking members 12 one by one. A locking hole 221 is formed in the mating member 22. Among them, the locking member 12 passes through and locks with the locking hole 221 of the corresponding mating member 22, and the filling component 30 is filled in the installation gap between the support surface 113 and the mating member 22.

[0043] Among them, as an example, the support body 11 only includes a support flat plate 111, and the top surface of the support flat plate 111 is configured to form a support surface 113. As an example, the support body 11 may also include a support flat plate 111 and a plurality of support bosses 112 protruding from the top surface of the support flat plate 111. All the support bosses 112 correspond to all the locking members 12 one by one. The top surfaces of all the support bosses 112 jointly form a support surface 113, and the locking members 12 protrude on the top surfaces of the corresponding support bosses 112. In the embodiment where the support body 11 includes a support flat plate 111 and support bosses 112, the filling assembly 30 is filled in the installation gap between the support surface 113 and the mating member 22, which means that the filling assembly 30 is filled in the installation gap between the top surface of the support boss 112 and the mating member 22. In this embodiment, there is a certain height difference between the support surface 113 and the top surface of the support flat plate 111 to facilitate a larger space for operating the filling assembly 30 to be filled in the installation gap between the support surface 113 and the mating member 22.

[0044] Among them, the support body 11 is usually made of sheet metal, plastic or other materials with high mechanical strength. When the container battery 20 is installed on the vehicle body 10, since the weight distribution inside the container battery 20 is not uniform, in order to prevent the support body 11 from deforming due to uneven stress, a load-bearing beam can be provided on the bottom side of the support body 11. Specifically, the positions on the support body 11 where the locking members 12 are provided usually bear a large load. Therefore, corresponding load-bearing beams can be designed at each position on the bottom side of the support body 11 and aligned with each locking member 12. The load-bearing beams are used to share the weight of the container battery 20, thereby providing the support strength of the entire support body 11 to prevent the support body 11 from deforming due to uneven stress.

[0045] The container body 21 is the main functional part of the container battery 20, which usually includes a box body and batteries arranged inside the box body. The bottom of the box body has a plurality of cross beams arranged at intervals along the length direction of the container body 21. It is worth mentioning that the cross beam refers to a beam structure extending along the width direction of the container body 21.

[0046] The mating member 22 is locked with the corresponding locking member 12 to realize the installation of the container battery 20 and the vehicle body 10. Specifically, the mating member 22 is a corner fitting, and the locking member 12 can be a twist lock, a turn lock, etc. As an example, the mating member 22 can be provided at each corner of the bottom of the container body 21, or, the mating member 22 can also be provided between every two adjacent corners arranged along the length direction of the container body 21 at the bottom of the container body 21. As an example, the mating member 22 can also be provided at each corner of the bottom of the container body 21 and between every two corners arranged along the length direction of the container body 21 at the bottom of the container body 21.

[0047] During operation, when the battery vehicle 100 starts, stops suddenly, and turns following the locomotive, the impact force on the container battery 20 is relatively large. The traditional method of only arranging the fitting 22 at the corner of the container main body 21 will greatly increase the load requirement at the corner. To reduce the shear force at the corner, fittings 22 are arranged at each corner of the bottom of the container main body 21, and fittings 22 are also arranged between every two corners at the bottom of the container main body 21 and along the length direction of the container main body 21. When the fitting 22 is locked with the locking member 12 one by one, the fixing points between the container battery 20 and the vehicle body 10 are increased, thereby reducing the force on the corner of the container battery 20 and being able to constrain the container battery 20 circumferentially, avoiding phenomena such as displacement, misalignment, and rollover of the container battery 20 during movement, and improving the safety performance of the battery vehicle 100. Specifically, the filling component 30 can be a gasket 32, elastic sponge, etc., which can be specifically set according to requirements. The installation gap between the support surface 113 and the bottom surface of each fitting 22 is filled with the filling component 30.

[0048] In this application, by designing the filling component 30 to be filled in the installation gap between the support surface 113 and the fitting 22, the fitting 22 can be supported, solving the problem of uneven force on the crossbeam and deformation caused by the container battery 20 being in a suspended state. The reliability and safety of the installation of the container battery 20 are improved, and the later maintenance of the container battery 20 is also relatively simple.

[0049] In addition, by using the locking method of the locking member 12 and the fitting 22, when the locking member 12 is locked with the fitting 22, the fixing of the container battery 20 can be realized. When the locking member 12 and the fitting 22 are unlocked, it is convenient to disassemble the container battery 20. This method has a firm fixation and is convenient for disassembling and repairing the container battery 20. Moreover, the container battery 20 is installed and supported by multiple locking members 12 cooperating with multiple fittings 22, thereby restricting the displacement of the container battery 20.

[0050] Please refer to again Figures 5 to 8 In some alternative embodiments, the filling component 30 includes at least two gasket units 31 arranged along the first direction X, and the gasket units 31 extend out of the opposite sides of the fitting 22 along the second direction Y intersecting the first direction X; the battery vehicle 100 further includes a fixing component 40, and the fixing component 40 includes two constraining members 41, one of the constraining members 41 is used to constrain the first ends of all the gasket units 31 extending out of one side of the fitting 22, and the other constraining member 41 is used to constrain the second ends of all the gasket units 31 extending out of the other side of the fitting 22.

[0051] Among them, the gasket unit 31 may include one or more gaskets 32 stacked together. According to the size of the installation gap between the fitting 22 and the support surface 113, the number of gaskets 32 with a size adapted to the installation gap is selected until the gasket unit 31 can fill the gap between the fitting 22 and the support surface 113. The number of gaskets 32 in different gasket units 31 may be the same or different, which is specifically determined according to the size within the space where the gasket unit 31 is located. To improve the filling effect, the gaskets 32 are usually set to be relatively thin. Taking two gasket units 31 as an example, all the gaskets 32 in one gasket unit 31 are inserted from one side arranged along the first direction X, and all the gaskets 32 in the other gasket unit 31 are inserted from the other side arranged along the first direction X to fill the installation gap between the fitting 22 and the support surface 113.

[0052] The gasket 32 has a C-shaped structure, and the groove in the middle of the gasket 32 can avoid the locking member 12.

[0053] Take Figure 1 as an example. The first direction X is consistent with the length direction of the container body 21, and the second direction Y is consistent with the width direction of the container body 21. Of course, the first direction X and the second direction Y are not limited to the above one case and may also be other directions. For example, the first direction X and the second direction Y are both directions intersecting with the length direction and the width direction of the container body 21. The specific setting of the first direction X and the second direction Y is not limited here.

[0054] It is defined that the fitting 22 has a first side and a second side oppositely arranged along the second direction Y. Each gasket 32 in each gasket unit 31 extends out of the first side and the second side of the fitting 22 along the second direction Y. The two restraint covers are butted along the second direction Y. After butt-joint, one of the restraint members 41 is used to restrain the first ends of all the gaskets 32 extending out of the first side in all the gasket units 31, and the other restraint member 41 is used to restrain the second ends of all the gaskets 32 extending out of the second side in all the gasket units 31.

[0055] As an example, the restraint member 41 may be a tightening sleeve, a tightening belt or other restraint structures.

[0056] By providing two restraint members 41, all the gasket units 31 can be tightened into a whole, reducing the risk of relative movement of all the gasket units 31 with respect to the fitting 22 and the support body 11, and making the installation and filling functions of the gasket units 31 more reliable. Moreover, the butt-joint direction of the two restraint covers intersects or even is perpendicular to the arrangement direction of the gasket units 31, thereby reducing the displacement of the gasket units 31 and improving the reliability of fixing the gasket units 31. In some alternative embodiments, the restraint member 41 is a restraint cover that covers the first ends of all the gasket units 31 it restrains or the second ends of all the gasket units 31.

[0057] Specifically, the restraining cover can be a hollow structure with one end open and the other end closed. After the two restraining covers are butted, the openings of the two restraining covers are arranged opposite to each other. Alternatively, the restraining cover can also be a hollow structure with one end open and one side open. After the two restraining covers are butted, the openings at one end of the two restraining covers are arranged opposite to each other, and the openings on one side of the two restraining covers face the supporting surface 113.

[0058] The design of the restraint member 41 in the form of a restraining cover facilitates the installation of the restraint member 41 and the tightening of the first ends or the second ends of all the gasket units 31 it restrains, improving the installation efficiency.

[0059] Furthermore, in some alternative embodiments, the restraining cover partially extends into the space between the filling assembly 30 and the mating member 22. In this way, the restraining cover can also serve as part of the filling assembly 30, reducing the setting of the gasket 32. In addition, by utilizing the gravity of the container battery 20, the restraining cover can be pressed against the filling assembly 30 to fix the restraining cover, so as to prevent the restraining cover from moving and weakening its restraining effect.

[0060] Please refer to Figures 6 to 10 , in some alternative embodiments, the fixing assembly 40 includes two connecting members 42. The two connecting members 42 are distributed on opposite sides of the restraint member 41 along the first direction X, and each connecting member 42 is detachably connected to the two restraint members 41 by an engaging connection with a concave-convex fit.

[0061] The connecting member 42 can be strip-shaped, rod-shaped, sheet-shaped, etc., and can be specifically set according to requirements. Each connecting member 42 is used to connect the two restraint members 41.

[0062] The two connecting members 42 are distributed on opposite sides of the restraint member 41 along the first direction X, and each connecting member 42 connects the two restraint members 41, which can fix the two restraint members 41 to prevent relative movement between the two restraint members 41 from affecting the restraining effect of the two restraint members 41. And each connecting member 42 is detachably connected to the two restraint members 41 by an engaging connection with a concave-convex fit, which can connect and disassemble the connecting member 42 and the restraint member 41, simplifying the disassembly and assembly difficulty of the fixing assembly 40.

[0063] In some alternative embodiments, engaging holes 421 are respectively formed at two opposite ends of the connecting member 42 along the second direction Y; convex columns 411 are respectively formed on two side surfaces of the constraining member 41 along the first direction X, and the two convex columns 411 of the two constraining members 41 on the same side are respectively engaged in the two engaging holes 421 on the connecting member 42 on the same side. That is to say, the two engaging holes 421 and the two convex columns 411 on the connecting member 42 on the same side are engaged with each other in a one-to-one correspondence. With the arrangement of the engaging holes 421 and the convex columns 411, when the two engaging holes 421 and the two convex columns 411 on the same side are aligned, by pressing the connecting member 42, the two convex columns 411 on the same side can be respectively inserted into the two engaging holes 421, which facilitates the installation and connection of the connecting member 42 and the constraining member 41.

[0064] In some alternative embodiments, external threads are formed on the convex columns 411; the fixing assembly 40 further includes fixing nuts 43, the fixing nuts 43 correspond to the convex columns 411 in a one-to-one correspondence, the fixing nuts 43 are sleeved on one end of the corresponding convex columns 411 passing through the engaging holes 421, and are screwed with the corresponding convex columns 411.

[0065] As an example, taking that each of the two opposite sides of each constraining member 41 has one convex column 411 as an example, the total number of the convex columns 411 on the two constraining members 41 is four, and thus the number of the nuts is also four, which correspond to the convex columns 411 in a one-to-one correspondence.

[0066] When the nuts are screwed with the corresponding convex columns 411, the connecting member 42 can be pressed against the two constraining members 41 to prevent the connecting member 42 from disengaging from the convex columns 411, ensuring the reliability of the connection between the connecting member 42 and the constraining member 41.

[0067] Please refer to Figures 1 to 10 , and below, the installation process of the container battery 20 and the vehicle body 10 will be described in detail.

[0068] First, insert several jacks under the bottom of the container main body 21 to lift the container battery 20, so that the fitting 22 on the container battery 20 is separated from the support surface 113, but it is necessary to ensure that the locking member 12 can be inserted into the locking hole 221 of the corresponding fitting 22. Then, insert the gasket unit 31 into the installation gap between the support surface 113 and each fitting 22. Since the sizes of the installation gaps between different fittings 22 and the support surface 113 are different, they can be filled by stacking different numbers of gaskets 32. When the gaskets 32 of the gasket unit 31 are stacked to a certain thickness, then insert two restraint covers, and the two restraint covers are butted, so as to fix all the gaskets 32 on the support surface 113. After the two cover plates are butted, insert the connecting member 42 on the two convex columns 411 on the two restraint covers on the same side for fixation, and finally screw in the nut to fix and restrain the connecting member 42 through the nut. Finally, gradually loosen the jacks under the bottom of the container main body 21 until the fitting 22 at the bottom of the container main body 21 abuts against the cover, and then operate the locking member 12 to lock with the fitting 22, so as to realize the fixation of the container battery 20.

[0069] Please refer to Figure 11 , in some alternative embodiments, the battery vehicle 100 further includes multiple pairs of traveling wheels 50. All pairs of traveling wheels 50 are arranged on the bottom side of the support main body 11 facing away from the locking member 12 and are spaced along the length direction of the support main body 11. Each pair of traveling wheels 50 is spaced along the width direction of the support main body 11. The arrangement of multiple pairs of traveling wheels 50 facilitates the battery vehicle 100 to follow the locomotive.

[0070] It is worth mentioning that the length direction of the support main body 11 is the same as the length direction of the container main body 21, and the width direction of the support main body 11 is the same as the width direction of the container main body 21.

[0071] Please refer to Figure 3 , Figure 4 and Figure 11 , the present application also provides a locomotive system 1000. The locomotive system 1000 includes a track 200, a locomotive, and the battery vehicle 100 described in any one of the above embodiments. The vehicle body 10 and / or the container main body 21 are connected to the locomotive, and the battery vehicle 100 walks synchronously with the locomotive on the track 200 under the drive of the locomotive.

[0072] The locomotive system 1000 in the present application has the effects brought by any one of the above embodiments, so it will not be elaborated here. For the above battery vehicle 100 and locomotive system 1000, by designing the filling component 30 to fill the installation gap between the support surface 113 and the fitting 22, the fitting 22 can be supported, solving the problem of uneven force on the cross beam and deformation caused by the container battery 20 being in a suspended state.
