[0002] With the rapid development of the new energy industry, new energy has been deeply favored by end customers due to its advantages of environmental protection and energy saving. The rail locomotive industry, which was originally powered by petroleum energy, is also gradually undergoing electrification transformation.

Therefore, it is necessary to configure a large-capacity battery system for the locomotive. The system is usually composed of multiple battery boxes. Since the battery box itself is heavy, it is usually difficult to install it on the shelf due to the structure of the battery box mounting frame. In addition, manual installation is mostly used, which has low efficiency and is prone to wear of the battery box. Therefore, the installation of the battery box on the shelf deserves attention.

DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. The accompanying drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other accompanying drawings or embodiments can be obtained based on these accompanying drawings or embodiments without paying creative work. The adjustments and improvements made without departing from the concept of the present application all belong to the protection scope of the present application.

[0029] In order to simplify the drawings, each figure only schematically shows the parts related to the embodiments, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only a part of the components with the same structure or function is schematically drawn, and there may be more or less components with the same structure or function in reality.

[0030] In this application, unless otherwise clearly specified and limited, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe associated objects, and cannot be understood as indicating or implying the relative importance or order between associated objects; in addition, they do not represent the number of associated objects. "Multiple" includes two or more, and other quantifiers are similar. " / " is used to describe the relationship between associated objects, which indicates the "or" relationship between associated objects. "And / or" is used to describe the relationship between associated objects, which includes any combination relationship between associated objects, such as "a and / or b" includes: "alone a", "alone b", or "a and b". "One or more" or "at least one" in multiple objects refers to any object or any combination of multiple objects, such as "one or more of a1, a2, a3" or "at least one of a1, a2, a3" includes: "alone a1", "alone a2", "alone a3", "a1 and a2", "a1 and a3", "a2 and a3" or "a1, a2 and a3".

[0031] The locomotive needs to overcome the vibration environment during operation. The traditional battery box mounting frame design cannot meet the vibration requirements during the operation of the locomotive, so an improved design is needed. The prior art designs a battery box mounting support plate in the battery box mounting frame, and pushes the battery box directly into it. Since the bottom of the profiles on both sides of the battery box is relatively sharp, when the battery box slides on the support plate, the paint surface on the support plate will be damaged. In addition, the paint surface at the bottom of the battery box mounting frame will be scratched during the movement, resulting in a decrease in the anti-corrosion ability of the battery box mounting frame. In other designs of the prior art, a crossbeam is added between the column beams of the battery box mounting frame to increase the structural strength of the battery box mounting frame during movement. However, the addition of the crossbeam will affect the installation of the fork (the upper and lower battery box mounting compartments are separated), and it can only be installed by manual lifting. Since the battery box itself has a certain weight, it is time-consuming and laborious during the handling process. The battery box needs to overcome a certain friction force when pushed into the cluster, and the conventional installation method cannot guarantee efficiency. This application effectively solves the technical problems of large wear and unstable installation of the battery box caused by vibration during the operation of the locomotive by designing the frame, support part and friction part of the battery box mounting frame.

[0032] The following is a description with reference to the accompanying drawings:

[0033] Please refer to Figure 1 , which is a schematic diagram of a battery box mounting frame structure provided in an embodiment of the present application. Figure 1As shown, it includes: a frame 100, the frame 100 includes a plurality of carrying spaces 110, the carrying space 110 includes a first opening 111, which is used to load a battery box; a support portion 200, which is arranged on both sides of the carrying space 110 and along the loading direction of the battery box, and a side of the support portion 200 close to the side wall of the carrying space 110 is vertically connected with a first flange 300, and the first flange 300 is fixedly connected to the frame 100; a friction portion 400, which is arranged on the support portion 200, and is used to assist the battery box to slide into the carrying space 110.

[0034] When the battery box mounting frame is loaded with a battery box, the battery box is loaded into the carrying space 110 from the first opening 111, and the overall weight of the battery box is jointly borne by the support portion 200 and the frame 100. The support portion 200 and the first flange 300 can be designed as an integral whole, such as being set as an L-shaped bent sheet metal, and the support portion 200 is fixedly connected to the frame 100 through the first flange 300 to bear the battery box. The surface material of the friction portion 400 can be a relatively smooth insulating material, which has a lower hardness than the profile of the battery box and has a certain wear resistance, providing a lower friction force for the battery box, and sliding into the carrying space 110 when the battery box is pushed into the battery box mounting frame. Since the carrier carrying the battery box, such as a locomotive, is in motion, if the battery box is directly placed on the support portion 200, due to the influence of inertia, the battery box may slide on the support portion 200, damaging the paint surface on the surface of the support portion 200, thereby reducing the anti-corrosion ability of the support portion, and the design of the friction portion 400 can reduce the occurrence of the above situation.

[0035] In some embodiments, the friction portion 400 includes a first friction structure 410 disposed on the support portion 200 , and a second friction structure 420 disposed perpendicular to the first friction structure 410 . The second friction structure 420 is disposed on a side wall of the bearing space 110 .

[0036] After entering the carrying space 110, the bottom of the battery box contacts the first friction structure 410 provided on the support part 200, thereby reducing the vibration of the locomotive during movement, which causes the bottom of the battery box to directly contact the support part 200, reduces wear, reduces the shaking of the battery box, and improves the stability of the battery box installation. The side of the battery box contacts the second friction structure 420, which reduces the wear on the side of the battery box while limiting and reducing the lateral movement of the battery box.

[0037] The first friction structure 410 and the second friction structure 420 can form a whole, together forming the friction part 400, and can be integrally formed during manufacturing to improve production efficiency; at the same time, the bottom edge of the battery box is relatively sharp, and the first friction structure 410 and the second friction structure 420 can wrap the edge of the battery box to prevent bumps and improve the durability of the battery box. The first friction structure 410 and the second friction structure 420 can be two independent structures, set at appropriate positions, and also play the role of supporting the battery box at the bottom and sides. The separated structures can save production costs and provide support areas and support positions in a more targeted and flexible manner. The first friction structure 410 and the second friction structure 420 can be fixedly connected to the support part 200 through at least one mounting hole, respectively, to prevent the first friction structure 410 and the second friction structure 420 from falling off during the loading and bearing process of the battery box. The second friction structure 420 can be fixedly connected to the frame 100 to further improve the stability of the second friction structure 420.

[0038] The frame 100 includes: four column beams 121, which are distributed at the four corners of the frame 100, and the four column beams are connected by a plurality of cross beam groups 130 to form the frame 100; the cross beam group 130 includes: four cross beams 131, and the four cross beams 131 are respectively located between two adjacent column beams 121; wherein, a bearing space 110 is formed between two adjacent cross beam groups 130.

[0039] The four beams 131 of the beam group 130 together form a rectangular frame, which is horizontally arranged and bears the battery box at the same time to prevent the battery box from tilting. The frame 100 may include six column beams 121, which are connected with a plurality of beam groups 130 to form two columns of frames, and the two columns of frames share two column beams 121; or include eight column beams 121, which are connected with a plurality of beam groups 130 to form two or three columns of frames. When two columns of frames are formed, the columns 121 are not shared between the frames, and when three columns of frames are formed, the columns 121 are shared between the frames. Therefore, when there are multiple columns of frames, the columns 121 may be shared between the frames, or they may not be shared. The number of frame columns is not specifically limited here, and the number of bearing spaces 110 formed between two adjacent beam groups 130 in the plurality of beam groups 130 is not specifically limited here. The battery box mounting racks formed by the above structure are all within the protection scope of this application. The size of the carrying space 110 , the width of the first opening 111 , the length of the support portion 200 , and the lengths of the first friction structure 410 and the second friction structure 420 in the friction portion 400 are designed based on the size of the battery box and are not specifically limited here.

[0040] A second flange 500 perpendicular to the support portion 200 is connected between one end of the support portion 200 away from the first opening 111 , and the second flange 500 is used to limit the battery box.

[0041] The height of the second flange 500 is higher than the support part 200. When the battery box mounting frame is loaded with the battery box, the battery box is prevented from being pushed in beyond the frame 100, and the battery box is prevented from sliding from the position opposite to the first opening 111. When there is at least one battery box mounting hole on the battery box, the second friction structure 420 and the support part 200 can be provided with battery box mounting frame mounting holes corresponding to the number and position of the battery box mounting holes; the battery box mounting frame mounting holes can be provided through the second friction structure 420 and the support part 200, and the battery box mounting holes and the battery box mounting frame mounting holes can be connected and fixed by bolts or fixing pins, so as to further improve the stability of the battery box on the battery box mounting frame.

[0042] In one embodiment, the first flange 300 extends toward one side of the bearing space 110 , and the second friction structure 420 is disposed close to the first flange 300 .

[0043] In one embodiment, the first flange 300 extends toward a side away from the bearing space 110 , the second friction structure 420 is disposed close to the frame 100 , and a plurality of reinforcing ribs 600 are disposed between the first flange 300 and the support portion 200 .

[0044] The reinforcing rib 600 can be a triangular structure, for example, the reinforcing rib 600 is a right-angled triangle structure, one right-angled side is connected to the support part 200, and the other right-angled side is connected to the first flange 300. Through the stable triangular structure, the auxiliary support part 200 and the first flange 300 jointly support the battery box. When the reinforcing rib 600 is arranged on both sides of the bearing space 110, the position can be symmetrical or asymmetrical, and the number can be the same or different, and it is arranged based on the load-bearing requirements of the battery box and the stress conditions of the battery box mounting frame. The reinforcing rib 600 can be other structures that can provide force support, such as a trapezoid, that is, the right angle of the right-angled triangle structure is removed, and it can also provide a force support point for the support part 200 and the first flange 300. It can also be a rectangular structure or other forms of support structure, which is not specifically limited here. The reinforcing rib 600 can play a role in strengthening the structural strength of the support part 200, and can also reduce the weight of the support part 200, thereby indirectly improving the energy density of the battery box mounting frame.

[0045] In one embodiment, it further includes: a plurality of positioning holes 700 , which are disposed on the crossbeam 131 at the first opening 111 , and the diameter of the positioning holes 700 is configured to be compatible with the positioning columns of a loading tool for loading the battery box.

[0046] The position of the positioning hole 700 is designed to cooperate with the positioning column of the loading tool for loading the battery box. For example, the number of the positioning hole 700 can be one, and the position of one positioning hole 700 can be set at the middle position of the crossbeam 131 at the first opening 111. Correspondingly, the positioning column of the loading tool is set at the middle position of the loading tool in the direction of loading the battery. When the positioning hole 700 is connected with the positioning column, the loading tool of the battery can be aligned with the first opening 111, and the battery box can be aligned with the carrying space 110 for loading smoothly and reliably, and the battery box can be loaded into the battery box mounting frame and placed on the support part 200 and the friction part 400. The number of the positioning holes 700 can be multiple, for example, two positioning holes 700 are set on the crossbeam 131 at the first opening 111, and the two positioning holes 700 are symmetrically arranged relative to the central axis of the crossbeam 131 in the direction of the column beam 121, thereby improving the alignment efficiency and accuracy of the loading tool aligning with the battery box mounting frame.

[0047] In one embodiment, a plurality of cross beams 800 are disposed between two column beams 121 on both sides of the bearing space 110 .

[0048] When the locomotive is moving, especially during acceleration and deceleration, the column beam will be subjected to a certain impact force, and the cross beam 800 can reduce the influence of these stresses on the strength of the frame structure; the battery box mounting frame may also be affected by the flatness of the ground or the weight balance of multiple battery boxes during use, generating forces in the front and rear directions (i.e., the direction in which the battery box is installed). Multiple cross beams 800 are designed on both sides of the battery box mounting frame to constrain the column beams, thereby improving the impact resistance and stress relief capabilities of the entire battery box mounting frame. The cross beams 800 can be symmetrically arranged on both sides of the bearing space 110 to balance the forces between the column beams 121 on both sides in the direction of locomotive travel. The number of cross beams 800 set on one side of the bearing space 110 can be determined based on the number of cross beam groups 130, such as one cross beam 800 is set for every two layers of cross beam groups 130; the number of cross beams 800 can be designed based on the force and load-bearing conditions of the overall frame 100 and the impact force generated by the acceleration and deceleration of the locomotive.

[0049] In one embodiment, fixing members 900 are disposed on both sides of the bottom of the frame 100 , and a groove body 910 is disposed on the opposite side of the two fixing members 900 . A plurality of fixing blocks 911 are disposed in the groove body 910 , and the fixing blocks 911 are provided with fixing screw holes 9111 that penetrate vertically.

[0050] The battery box mounting frame can be fixedly installed in scenes such as locomotives and energy storage stations. In order to improve the reliability of the battery box mounting frame loading the battery box, a fixing member 900 can be set at the bottom of the frame 100. It can be set on both sides or around the bottom of the frame 100, wherein the two sides can be the two sides of the direction perpendicular to the direction of the first opening 111 of the bottom of the battery box mounting frame; the two sides can be the two sides of the direction consistent with the direction of the first opening 111 of the bottom of the battery box mounting frame. The fixing members 900 on both sides are respectively provided with a groove body 910, the groove body 910 is relatively open, the first groove wall of the groove body 910 is fixedly connected to the crossbeam 131 of the frame 100, and the second groove wall of the groove body 910 (that is, the groove wall away from the crossbeam 131 and opposite to the first groove wall) is provided with a plurality of fixing blocks 911, and the number of fixing blocks 911 can be one or more. When a fixing block 911 is set, the position of the fixing block 911 can be set in the middle of the groove body or at a position on other groove bodies 910, and the entire battery box mounting frame is fixed to the ground or on the locomotive with bolts through the fixing screw holes 9111. When multiple fixing blocks 911 are provided, for example, two fixing blocks 911, the two fixing blocks 911 can be respectively provided at positions close to the column beam 121. In the fixing parts 900 provided around the bottom of the frame 100, the positions of the fixing blocks 911 can be set with reference to the above positions. The fixing blocks 911 inside the trough body 910 serve as the fixing points of the battery box mounting frame. Compared with the method of directly opening holes at the bottom of the column beam 121 of the frame 100, the processing accuracy of the fixed holes can be provided. Since the battery box mounting frame has a high weight and height, the hole positions are subjected to greater stress by directly opening holes at the bottom for fixing. Adding the fixing blocks 911 can reduce the influence of stress on the fixed holes of the trough body 910 and increase the stress resistance of the holes.

[0051] In order to facilitate the installation of the battery box on the battery box mounting rack in the above embodiments, the present application also provides a loading tool that is compatible with the battery box mounting rack provided in any of the above embodiments. Please refer to Figure 2 , shows a structural schematic diagram of a loading tool matched with a battery box mounting frame, including: a pallet 10, used for loading the battery box, the bottom of the pallet 10 is provided with a socket 11 matching the fork of the forklift, and one side of the pallet is provided with a closing opening 12 matching the first opening 111; a propulsion device 20, installed on the pallet 10, used to load the battery box from the pallet 10 through the first opening 111 and the friction part 400 to the carrying space 110.

[0052] The battery box is usually heavy, and it is inconvenient to carry and install it manually. At the same time, the batteries contained in the battery box need to avoid collision and falling as much as possible, and manual installation has the risk of damaging the batteries. Therefore, the handling and loading of the battery box are usually completed by forklift transportation and manual shelving. In the present application, the battery box can be hoisted into the pallet 10 by a hoisting device, and then the fork of the forklift is inserted into the socket 11. After the fork enters the socket 11 and reaches the specified position, the fork lifts and supports the entire loading tool and the battery box thereon, and transports it to the battery box mounting frame. After the fork is adjusted in position, it is aligned with the first opening 111 of the battery box mounting frame through the closing 12. At this time, the propulsion device 20 can push the battery box through the first opening 111 to load into the carrying space 110, and complete the shelving of the battery box.

[0053] Limiting flanges can be set around the tray 10, and a closing opening 12 can be set on the side where the battery box is pushed into the battery box mounting frame. The closing opening 12 is not set with a limiting flange in the direction facing the first opening 111, which facilitates the pushing of the battery box. The width of the closing opening 12 is designed based on the size of the battery box and is narrower than the width of the tray 10, thereby ensuring that the battery box can be pushed into the battery box mounting frame.

[0054] In one embodiment, it also includes: a first track 31 and a second track 32 arranged parallel to the surface of the tray 10, the first track 31 and the second track 32 are used to support the battery box, and one end of the first track 31 and the second track 32 is arranged toward the closing opening 12; a plurality of ball bearings 33 rotatably installed on the surface of the tray 10 are arranged between the first track 31 and the second track 32.

[0055] When the battery box is loaded into the loading tool, it is hoisted from the cutting board onto the first rail 31 and the second rail 32, and the battery box can be pushed along the first rail 31 and the second rail 32. The material setting of the first rail 31 and the second rail 32 can be consistent with the material setting of the friction part 400. The distance between the first rail 31 and the second rail 32 can accommodate the battery box to be pushed between the two rails. In order to reduce the friction resistance between the battery box and the first rail 31 and the second rail 32, a plurality of ball bearings 33 are provided in the space formed between the first rail 31 and the second rail 32. The ball bearings 33 are in contact with the bottom of the battery box, which can reduce the supporting force of the first rail 31 and the second rail 32, and can also reduce the friction between the battery box and the first rail 31 and the second rail 32 through the ball bearings 33, thereby improving the assembly efficiency.

[0056] In some embodiments, the propulsion device 20 includes: a driving motor 21, the output end of the driving motor 21 is connected to a main screw 22; at least one auxiliary screw 23, meshing with the main screw 22, and arranged parallel to the first track 31, the auxiliary screw 23 is installed on the tray 10 through a nut 24, and the end of the auxiliary screw 23 close to the closing opening 12 is connected to a push block 25, so that when the driving motor 21 is working, the auxiliary screw 23 pushes the battery box to move along the direction of the first track 31.

[0057] The drive motor 21 is designed with an external wiring harness connector to realize external control of the drive motor 21.
