[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] The embodiment of the present invention discloses an equipment box, which adopts a modular splicing design. Figure 12 As shown, it includes at least one set of support frames 2 hoisted on the vehicle body chassis 1. The vehicle body chassis 1 is equipped with multiple sets of equipment boxes, all of which are distributed along the length of the vehicle body chassis 1. For each equipment box, all support frames 2 are integrally spliced ​​and connected according to a set number along the length of the vehicle body chassis 1, as shown in the attached figure. Figure 1 As shown. The integrated splicing setting can improve the connection strength between the connected support frames 2, thereby improving the overall rigidity of the equipment box, so that the equipment box can withstand the impact and vibration caused by the uneven track, as well as the impact and vibration generated by the functional equipment 01, extending the service life of the equipment box. The set number in the text can be one, as shown in the attached Figure 2 There can also be two, as shown in the attached Figure 1 It should be noted that when the number of support frames 2 constituting the equipment box is not less than two, the two adjacent support frames 2 are designed as an integrated structure by sharing one side, as shown in the attached figure. Figure 1 As shown, the structure of the equipment box is more compact, the assembly is more convenient, and the rigidity is higher.

[0048] The equipment box in the present invention is formed by a set number of support frames 2 integrally spliced ​​along the length direction of the vehicle body chassis 1. In this way, the number of support frames 2 contained in each equipment box can be flexibly adjusted according to the number of functional devices 01 centrally arranged on the vehicle body chassis 1, thereby changing the structure of the equipment box so that the equipment box can adapt to different numbers of functional devices 01 in a compact layout, thereby improving the versatility of the equipment box.

[0049] Each support frame 2 is formed with a receiving groove, and at least one inner partition 21 is provided in the receiving groove. All inner partitions 21 are distributed along the width direction of the vehicle body chassis 1. Figure 1 and 2As shown, the inner partition 21 divides the accommodating groove into several independent installation cavities 22, and a functional device 01 is placed in each installation cavity 22. In this way, the number of inner partitions 21 of each support frame 2 can be flexibly adjusted according to the external dimensions of the functional device 01, so that the number and volume of the installation cavities 22 in each support frame 2 can be flexibly adjusted according to the external dimensions of the functional device 01, so that each support frame 2 is suitable for accommodating functional devices 01 of different specifications and different quantities.

[0050] In summary, the present invention optimizes the structure of the equipment box, unifies the specifications of the equipment box, and makes the structure of the equipment box flexible and changeable, so that the equipment box can adapt to functional devices 01 with different layouts and different specifications, and the equipment box has good versatility.

[0051] Each support frame 2 is provided with a plurality of mounting brackets 23 on both sides. Figure 1 and 2 As shown, each mounting bracket 23 is fixedly connected to the vehicle body chassis 1 through an adapter 3, so that the equipment box can be reliably hoisted on the bottom of the vehicle body chassis 1, making it easy to disassemble and assemble the equipment box from the vehicle body chassis 1 and reducing the difficulty of maintenance.

[0052] The adapter 3 is an integrated structure, and the cross section of the adapter 3 is E-shaped. Figure 8 As shown in the attached Figure 7 and 8As shown, the adapter 3 includes a fixing portion 31 fixedly connected to the vehicle body chassis 1, two supporting portions 32 fixedly provided on two opposite sides of the fixing portion 31, and a stopper portion 33 fixedly provided on one side of the fixing portion 31 facing the supporting portion 32 and located between the two supporting portions 32. In other words, the two supporting portions 32 and the stopper portion 33 are all provided on the same side of the fixing portion 31. The fixing portion 31 is in the shape of a flat plate and is parallel to the vehicle body chassis 1. The fixing portion 31 can be fixed to the bottom of the vehicle body chassis 1 by welding or riveting. The two supporting portions 32 are both L-shaped structures. The two supporting portions 32 are symmetrically provided on two opposite sides of the fixing portion 31. The two supporting portions 32 are used to support the two side edges of the mounting bracket 23. When the bolts are loose or broken, the supporting portions 32 can effectively prevent the equipment box from accidentally falling off, which is conducive to improving safety. The stopper 33 is in the shape of a square. In the direction perpendicular to the fixing portion 31, the extension length of the stopper 33 is less than the extension length of the supporting portion 32, so that a mounting gap is formed between the stopper 33 and the supporting portion 32 for inserting the mounting support 23. The mounting support 23 can be slidably mounted on the adapter 3 by means of insertion and withdrawal, which facilitates assembly and disassembly. A limiting groove 34 is formed between each supporting portion 32 and the stopper 33. A connecting bolt 4 passing through the supporting portion 32 and the mounting support 23 is installed in the limiting groove 34. By tightening the locking nut installed on the connecting bolt 4 with a wrench, the equipment box is reliably fixed to the adapter 3 through the connecting bolt 4. It should be noted that the stopper 33 is used to block the head of the connecting bolt 4 installed in the limiting groove 34, thereby limiting the loosening of the connecting bolt 4 due to the impact and swinging of the equipment box, and ensuring that the connecting bolt 4 is reliably connected.

[0053] As attached Figure 10 and 11 As shown, the vehicle underframe 1 includes a chassis floor 11 and two chassis side beams 12 fixedly mounted parallel to either side of the chassis floor 11. The chassis side beams 12 are used to enhance the rigidity of the vehicle underframe 1. The mounting brackets 23 include end brackets 231 located at the ends of the support frame 2 and intermediate brackets 232 located in the center of the support frame 2. The end brackets 231 are fixedly connected to the chassis side beams 12, while the intermediate brackets 232 are fixedly connected to the chassis floor 11. The equipment box is fixed using a three-point system, which increases the normal rigidity of the vehicle underframe 1, facilitating assembly and disassembly of the equipment box and preventing deformation of the vehicle underframe 1 caused by the equipment box.

[0054] The support frame 2 includes two parallel side frames 24. Figure 1 and 2As shown, the opposite sides of the two side frames 24 are fixed with guide strips 241. The guide strips 241 can slide with the guide grooves provided for the functional device 01 to guide the functional device 01 into the device box, reducing the difficulty of installing the functional device 01. To ensure that the guide strips 241 have sufficient load-bearing capacity, two guide strips 241 are installed in parallel on the inner side wall of each side frame 24. The two guide strips 241 are respectively located on the upper and lower sides of the side frame 24 to ensure that the side frame 24 is evenly stressed. In addition, it should be noted that the guide strip 241 in the side frame 24 is not a whole strip, but is divided into several sections by multiple inner partitions 21. Of course, the setting method of the guide strip 241 is not limited to this, and can be adjusted according to the specifications of the functional device 01.

[0055] As attached Figure 5 As shown, each side frame 24 includes two parallel outer panels 242 and several parallel reinforcing panels 243 fixedly mounted between the two outer panels 242. In other words, each side frame 24 is not a solid structure, which enables a lightweight design for the equipment box and prevents the equipment box from being too heavy and increasing the difficulty of assembly and disassembly. The reinforcing panels 243 are used to enhance the strength and rigidity of the side frame 24. In addition, the spacing between two adjacent reinforcing panels 243 located near the guide bar 241 is smaller than the spacing between the other two adjacent reinforcing panels 243. In other words, the reinforcing panels 243 near the guide bar 241 are arranged more closely, so that the guide bar 241 has sufficient rigidity to support the functional device 01, preventing the guide bar 241 from being bent and deformed by the functional device 01 due to the sparse placement of the reinforcing panels 243. This allows the equipment box to withstand heavier functional devices 01 and improves the reliability of the equipment box. Of course, the structure of the side frame 24 is not limited to this.

[0056] As attached Figure 1 and 2 As shown, the side frame 24 is provided with a plurality of heat dissipation holes 244, which allow the functional devices 01 in the equipment box to dissipate heat through the heat dissipation holes 244. All inner partitions 21 are fixed between the two side frames 24, and the heat dissipation holes 244 are staggered with all inner partitions 21 to prevent the inner partitions 21 from being directly opposite the heat dissipation holes 244, which would result in unreliable fixation of the inner partitions 21. Specifically, the side frame 24 is formed with two heat dissipation holes 244. Both heat dissipation holes 244 are rectangular holes, and both heat dissipation holes 244 are symmetrically arranged on either side of the side frame 24. For a single side frame 24, the sum of the areas of the two heat dissipation holes 244 is greater than the area of ​​the side frame 24, ensuring that the heat dissipation holes 244 of each side frame 24 are sufficiently large to improve heat dissipation efficiency. In addition, the inner partitions 21 are also provided with heat dissipation holes, which also facilitate heat dissipation of the functional devices 01 and prevent the normal operation of the functional devices 01 from being affected by the accumulation of large amounts of heat in the equipment box.

[0057] As attached Figure 1 and 2As shown, the support frame 2 also includes a bottom frame fixed to the bottom of the two side frames 24. The bottom frame is composed of a plurality of parallel bottom edge beams 25. This ensures that the bottom frame is lightweight while maintaining sufficient support strength, meeting the lightweight design requirements of the equipment box. The spacing between two adjacent bottom edge beams 25 can be adjusted according to the external dimensions of the functional device 01 being carried, and is not specifically limited here.

[0058] As attached Figure 6 As shown, the bottom side beam 25 is a U-shaped curved beam, and the two extensions 252 of the U-shaped curved beam are respectively fixed to the two side frames 24, thereby increasing the contact area between the side beam and the side frames 24, ensuring that the bottom side beam 25 is securely fixed, and thus improving the load-bearing capacity of the bottom side beam 25. The two ends of the bottom side beam 25 can be fixed between the two side frames 24 by welding, but the fixing method is not limited to this. In addition, to prevent the extensions 252 of the bottom side beam 25 from colliding and interfering with the functional device 01, avoidance grooves can be provided on opposite sides of the side frames 24, so that the extensions 252 are embedded in the avoidance grooves to prevent the extensions 252 from contacting the functional device 01.

[0059] The support frames 2 are assembled into the equipment box body according to the set number, and sealing strips 5 are fixed on both sides of the box body. Figure 9 As shown, the sealing strip 5 is used to seal the gap between the box body and the suspension frame to ensure that the bottom of the box has good sealing when the rail vehicle runs at high speed, which is beneficial to improving the speed level of the rail vehicle and making the equipment box suitable for rail vehicles with higher running speeds, such as maglev trains.

[0060] Mounting plates 6 are fixed to both sides of the box body. These plates are welded or riveted to the bottom outer sides of the two side frames 24. Two inclined plates are integrally formed on the side of the mounting plate 6 away from the side frames 24. These two inclined plates face each other to form a dovetail-shaped snap-fit ​​groove. Accordingly, the cross-section of the sealing strip 5 is triangular, forming a dovetail-shaped protrusion on one side of the sealing strip 5. This dovetail-shaped protrusion is snap-fitted into the dovetail-shaped snap-fit ​​groove, as shown in the attached diagram. Figure 9 As shown, the special assembly method between the mounting plate 6 and the sealing strip 5 can ensure that the sealing strip 5 is reliably fixed on both sides of the equipment box. Of course, the fixing method of the sealing strip 5 is not limited to this.

[0061] The bottom end of the inner partition 21 is bent to form a U-shaped hook 211. Figure 3 As shown, the U-shaped hook 211 is vertically connected to the inner partition 21. Two inner partitions 21 are installed in parallel in each support frame 2, and the U-shaped hooks 211 of the adjacent two inner partitions 21 face each other to form a hanging interface, as shown in the attached Figure 4As shown, it is used to hang functional devices 01. Functional devices 01 can be slidably installed on the hanging interface by pulling. The U-shaped hook 211 of the inner partition 21 not only enhances the rigidity of the bottom end of the inner partition 21, but also provides an interface for the installation of functional devices 01, thereby increasing the number of installation interfaces of the equipment box and accommodating the installation of a larger number of functional devices 01.

[0062] The top of the inner partition 21 is bent to form a reinforcement eave 212, as shown in the attached Figure 3 As shown, the reinforcing eaves 212 are L-shaped or T-shaped, and are used to enhance the top stiffness of the inner partition 21, thereby improving the stiffness of the equipment box as a whole, making the equipment box more load-bearing and having a longer service life.

[0063] The embodiment of the present invention further discloses a rail vehicle including the above-mentioned equipment box, and an installation solution for the equipment box with unified specifications, which shortens the invalid installation time, improves the installation efficiency and reduces the manufacturing cost.

[0064] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0065] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
