Description

Technical Field

[0001] This invention relates to the field of power battery technology, and in particular to a modular device for power batteries in new energy locomotives. Background Technology

[0002] Many industrial and mining enterprises are now choosing new energy rail locomotives to replace traditional internal combustion diesel locomotives for traction and shunting operations.

[0003] However, since the core of new energy locomotives is the power battery system, and the locomotives are compact and require a large amount of battery power, the design and installation process is relatively complex, the design and installation cycle is long, and the assembly workers need a high level of professionalism. Usually, four professional assembly workers are needed to assemble the power battery (battery PAC rack assembly, power cable connection, thermal management system assembly, and fire protection system assembly).

[0004] To address the shortcomings of the aforementioned technologies, we propose a modular device for power batteries in new energy locomotives. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular device for power batteries in new energy locomotives.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular power battery device for new energy locomotives includes a frame support assembly, a battery module, and a shock absorption mechanism. The battery module includes a structural plate on which a power battery pack is mounted. A discharge port is fixedly installed at the rear end of the power battery pack. A structural seat is fixedly installed at the upper rear of the structural plate. An outer sleeve groove is fixedly installed at the front of the structural seat. A slider is slidably installed inside the outer sleeve groove. A metal electrode is fixedly installed at the front of the slider and inserted into the discharge port. Several compression springs are fixedly connected between the slider and the inner side of the outer sleeve groove. A limit lock block is slidably inserted at the front of the structural plate. A pull handle is fixedly installed at the bottom of the limit lock block. Several sets of tension springs are fixedly connected between the pull handle and the bottom of the structural plate.

[0008] In this invention, the vehicle frame support assembly includes a base plate and a conical top cover. A plurality of columns are fixedly connected between the base plate and the conical top cover. A central support plate is fixedly connected between the plurality of columns. A glass mounting groove and a sliding door mounting groove are provided on the upper side of the central support plate.

[0009] In this invention, the shock absorption mechanism includes an L-shaped structural block, a damper is fixedly installed on the upper side of the L-shaped structural block, a top plate is fixedly installed on the upper end of the damper, a shock absorption spring is sleeved on the outer side of the damper, and a cylinder is fixedly installed on the upper side of the top plate.

[0010] In this invention, the limiting lock block abuts against the front side of the power battery pack, and a handle is fixedly installed on the front side of the power battery pack.

[0011] In this invention, a limiting frame is fixedly installed on the upper side of the structural plate, and two sets of limiting sleeves are fixedly installed on the upper side of the limiting frame. The power battery pack is slidably inserted into the inner side of the limiting frame.

[0012] In this invention, a plurality of heat dissipation holes are evenly distributed on the structural plate, and mounting holes are provided at the four corners of the structural plate, the mounting holes being slidably fitted onto the outside of the cylinder.

[0013] In this invention, an electrical interface is provided on the rear side of the structural base, and a metal cable is electrically connected between the electrical interface and the metal electrode. A raised outer ring is provided on the outer side of the outer sleeve groove port, and a water-repellent plate is symmetrically fixed on the outer wall of the outer sleeve groove.

[0014] In this invention, reinforcing diagonal braces are fixedly connected between the columns, louvers are provided on the side of the conical top cover, an exhaust fan is fixedly installed inside the louvers, the louvers are connected to the bottom of the conical top cover, a temperature sensor and a smoke sensor are fixedly installed at the bottom of the conical top cover, and a fire management box, an integrated BMS high-pressure box and an industrial refrigeration air conditioner are fixedly installed on the upper side of the base plate.

[0015] In this invention, the fire management box is equipped with a hexafluoropropane storage tank and a high-pressure pump. A nozzle is fixedly installed at the output end of the high-pressure pump. A solenoid valve is installed between the hexafluoropropane storage tank and the high-pressure pump. The nozzle passes through to the upper side of the intermediate support plate. An air inlet pipe is installed on the industrial refrigeration air conditioner. A dustproof mesh cover is fitted at the port of the air inlet pipe. The upper end of the air inlet pipe enters the upper side of the intermediate support plate.

[0016] In this invention, the L-shaped structural block is screwed onto the side wall of the column, and the upper outer wall of the cylinder is provided with threads, and an installation nut is screwed onto the outer side of the threads.

[0017] Compared with related technologies, the modular device for power batteries of new energy locomotives proposed in this invention has the following advantages:

[0018] In this invention, a modular power battery device for new energy locomotives is described. Several sets of battery modules are installed independently within a frame support assembly. Each set of battery modules has a power battery pack slidably inserted and installed on the upper side of a structural plate. The perimeter of the power battery pack is limited by a limiting frame and a limiting sleeve. A tension spring drives a limiting locking block to abut against the front of the power battery pack, while a compression spring provides a rebound force to keep the metal electrodes on the slider in contact with the discharge port on the rear of the power battery pack. This achieves synchronous electrical connection after the power battery pack is slidably installed and locked. The installation and disassembly of each power battery pack is very convenient, requiring no highly skilled personnel for rapid disassembly and assembly. This enables rapid battery swapping for new energy locomotives and is highly practical.

[0019] In this invention, a modular power battery device for new energy locomotives is described. Through the setting of a frame support component, the entire structure is made into a car body shape according to the outer contour of the locomotive cabin, replacing the locomotive power cabin and realizing the modularization of the power battery system. A fire management box, an integrated BMS high-voltage box, and an industrial refrigeration air conditioner are simultaneously installed in the frame support component. Temperature sensors and smoke sensors are set at the bottom of the conical top cover to monitor the internal temperature and smoke of the entire power supply device during operation. The industrial refrigeration air conditioner is used to cool the battery module. In addition, when the smoke sensor detects that the battery is burning and on fire, the high-pressure pump inside the fire management box is activated to spray hexafluoropropane from the hexafluoropropane storage tank to prevent the fire from spreading and improve the safety of the power battery.

[0020] In this invention, a modular power battery device for new energy locomotives is provided. The shock absorption mechanism is set at the four corners of each battery module. The combination design of the damper and compression spring on the mechanism is used to absorb the vibration at the four corners of the battery module. This reduces the shaking transmitted to the battery module during the operation of the rail locomotive, improves the protection of the power battery, prevents components from loosening, and extends the service life of the power battery.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First embodiment:

[0034] Please refer to the reference. Figures 1-2 and Figures 4-9In the first embodiment of the present invention, a modular power battery device for a new energy locomotive includes a frame support assembly 1, a battery module 8, and a shock absorption mechanism 9. The battery module 8 includes a structural plate 81, on which a power battery pack 85 is disposed. A discharge port 86 is fixedly installed at the rear end of the power battery pack 85. A structural seat 82 is fixedly installed at the upper rear side of the structural plate 81. An outer sleeve groove 83 is fixedly installed at the front side of the structural seat 82. A slider 817 is slidably installed inside the outer sleeve groove 83. The front side of the slider 817... A metal electrode 818 is fixedly installed and inserted into the inner side of the discharge port 86. Several compression springs 819 are fixedly connected between the slider 817 and the inner side of the outer sleeve groove 83. A limit lock block 812 is slidably inserted into the front side of the structural plate 81. A pull handle 813 is fixedly installed at the bottom of the limit lock block 812. Several sets of tension springs 814 are fixedly connected between the pull handle 813 and the bottom of the structural plate 81. The limit lock block 812 abuts against the front side of the power battery pack 85. A handle 87 is fixedly installed on the front side of the power battery pack 85.

[0035] It should be noted that the power battery PACK 85 uses lithium iron phosphate power batteries, and its casing is a standard C box (approximately 35kWh). This invention is used for the power supply of new energy rail locomotives in industrial and mining enterprises. The control of electrical components in each module and component is ultimately connected to the vehicle system of the new energy rail locomotive through the final assembly wiring harness, and is uniformly managed and controlled by the vehicle system of the new energy rail locomotive.

[0036] With the above-described configuration, pulling the handle 813 will cause the limit lock block 812 to move downwards and disengage from the limit. At this point, the power battery pack 85 can be slid out along the limit frame 89 using the handle 87. Installation is performed by reversing the operation. The rebound force of the compression spring 819 ensures that the metal electrode 818 is always tightly connected with the discharge port 86, achieving simultaneous completion of installation and electrical connection, significantly reducing assembly difficulty, and allowing for quick operation even without highly skilled personnel.

[0037] In this method, a limiting frame 89 is fixedly installed on the upper side of the structural plate 81, and two sets of limiting sleeves 810 are fixedly installed on the upper side of the limiting frame 89. The power battery pack 85 is slidably inserted into the inner side of the limiting frame 89.

[0038] With the above-mentioned setup, the limiting frame 89 and the limiting sleeve 810 form a double limiting structure, which can position and constrain the power battery PACK pack 85 from the periphery and top side, preventing it from shifting laterally or swaying up and down during locomotive operation, and ensuring the connection stability between the metal electrode 818 and the discharge port 86.

[0039] In this method, a number of heat dissipation holes 811 are evenly distributed on the structural plate 81, and mounting holes 88 are opened at the four corners of the structural plate 81. The mounting holes 88 are slidably sleeved on the outside of the cylinder 95.

[0040] With the above-mentioned configuration, the heat dissipation hole 811 can quickly dissipate the heat generated by the power battery pack 85 during operation, avoiding excessive local temperature from affecting battery performance; the structural plate 81, through the cooperation of the mounting hole 88 and the cylinder 95, achieves precise docking with the shock absorption mechanism 9, providing a stable mounting foundation for the battery module 8.

[0041] In this method, an electrical interface 84 is installed on the rear side of the structural base 82. A metal cable 820 is electrically connected between the electrical interface 84 and the metal electrode 818. A raised outer ring 816 is provided on the outer side of the outer sleeve groove 83. A water-repellent plate 815 is symmetrically fixed on the outer wall of the outer sleeve groove 83.

[0042] With the above-mentioned configuration, the electrical interface 84 enables the battery module 8 to be quickly connected to the external circuit, and the metal cable 820 ensures stable current transmission. The raised outer ring 816 enhances the hydrophobic sealing of the outer casing 83 port, and the water-repellent plate 815 effectively prevents moisture from entering the inner part of the outer casing 83, protecting the metal electrode 818 and compression spring 819 from moisture, improving the service life of the components, avoiding the risk of leakage, and improving the safety of use.

[0043] Second embodiment:

[0044] Please refer to the reference. Figure 3 In this embodiment, the frame support assembly 1 includes a base plate 11 and a conical top cover 12. A plurality of columns 13 are fixedly connected between the base plate 11 and the conical top cover 12. A middle support plate 14 is fixedly connected between the plurality of columns 13. A glass mounting groove 16 and a sliding door mounting groove 17 are provided on the upper side of the middle support plate 14.

[0045] It should be noted that the glass mounting groove 16 is used for the later installation of safety transparent glass, making the working space of several sets of battery modules 8 an internal space, reducing the interference of external dust and improving the protection of the power battery. In addition, the sliding door mounting groove 17 is used to install a glass sliding door, so that the front of the entire enclosed protective space formed by the safety transparent glass can be opened, which is convenient for the daily battery replacement or maintenance needs of the staff. Furthermore, the heat dissipation and fire protection work in this invention both work on the enclosed protective space formed by the safety transparent glass.

[0046] With the above configuration, the base plate 11, the conical top cover 12 and the column 13 form a stable frame support structure. The middle support plate 14 provides a structural bearing surface for the later installation of safety transparent glass and sliding doors. At the same time, it forms a closed space with the outer side where safety transparent glass and sliding doors are installed, as well as the upper conical top cover 12, reducing the intrusion of external dust and facilitating daily battery swapping and maintenance.

[0047] In this configuration, reinforcing diagonal braces 15 are fixedly connected between the columns 13. Louvered windows 18 are opened on the side of the conical top cover 12. An exhaust fan is fixedly installed inside the louvered windows 18. The louvered windows 18 are connected to the bottom of the conical top cover 12. Temperature sensors and smoke sensors are fixedly installed at the bottom of the conical top cover 12. A fire management box 2, an integrated BMS high-voltage box 4, and an industrial refrigeration air conditioner 5 are fixedly installed on the upper side of the base plate 11. The integrated BMS high-voltage box is a standardized component that integrates the core control functions of the battery management system (BMS) with the high-voltage power distribution unit (including contactors, fuses, pre-charge circuits, etc.). It is mainly used for high-voltage power distribution, battery status monitoring, and safety protection of the power battery system. It is a mature technology widely used in new energy vehicles, energy storage equipment, and other fields. Its integrated design not only simplifies the layout of the high-voltage system of the whole vehicle / equipment and reduces installation space and wiring harness costs, but also improves the stability and reliability of the system through mature integration solutions. It has formed a standardized design, production, and application system.

[0048] Through the above-mentioned setup, the reinforced diagonal brace 15 further enhances the connection strength between the columns 13 and strengthens the overall rigidity of the frame support assembly 1; the temperature sensor and smoke sensor monitor the internal environment in real time, and the industrial refrigeration air conditioner 5 introduces clean air (dust filter cover 7 filters impurities) through the air intake pipe 6 to achieve cooling; when a fire is detected, the fire management box 2 sprays the extinguishing agent in the hexafluoropropane storage tank through the nozzle 3 via the high-pressure pump, forming a complete protection system of "monitoring-cooling-fire extinguishing"; the integrated BMS high-voltage box 4 realizes the rational distribution of high-voltage power and real-time control of battery status, ensuring the safe and stable operation of the entire power system.

[0049] In this method, a hexafluoropropane storage tank and a high-pressure pump are installed inside the fire management box 2. A nozzle 3 is fixedly installed at the output end of the high-pressure pump. A solenoid valve is installed between the hexafluoropropane storage tank and the high-pressure pump. The nozzle 3 passes through to the upper side of the middle support plate 14. An air inlet pipe 6 is installed on the industrial refrigeration air conditioner 5. A dustproof mesh cover 7 is fitted at the port of the air inlet pipe 6. The upper end of the air inlet pipe 6 enters the upper side of the middle support plate 14.

[0050] Through the above-mentioned setup, the dust filter 7 can filter dust and impurities in the air intake pipe 6, preventing dust accumulation in the internal components of the industrial refrigeration air conditioner 5 from affecting the cooling efficiency; the nozzle 3 extends directly to the battery module 8 installation area on the upper side of the middle support plate 14. After the hexafluoropropane is released, it quickly vaporizes and diffuses into the fire. Its molecules decompose at high temperatures, releasing fluorine-containing free radicals. These free radicals can react with hydrogen free radicals and hydroxyl free radicals generated in the combustion reaction, interrupting the continuous transmission of the combustion chain and fundamentally inhibiting the combustion reaction. At the same time, the hexafluoropropane absorbs a large amount of heat during vaporization, reducing the ambient temperature of the fire and slowing down the combustion rate. In addition, after its diffusion, it occupies the space of the combustion area, diluting the oxygen concentration in the air and forming a slight suffocation effect, further assisting in fire extinguishing, and ultimately achieving the effect of rapid and efficient fire extinguishing without leaving water stains or corroding equipment.

[0051] Third embodiment:

[0052] Please refer to the reference. Figure 10 In this embodiment, the damping mechanism 9 includes an L-shaped structural block 91. A damper 92 is fixedly installed on the upper side of the L-shaped structural block 91. A top plate 93 is fixedly installed on the upper end of the damper 92. A damping spring 94 is sleeved on the outer side of the damper 92. A cylinder 95 is fixedly installed on the upper side of the top plate 93. The L-shaped structural block 91 is screwed onto the side wall of the column 13. A thread 96 is provided on the outer wall of the upper end of the cylinder 95. An installation nut 97 is screwed onto the outer side of the thread 96.

[0053] Through the above-mentioned configuration, the L-shaped structural block 91 achieves a stable connection between the shock absorption mechanism 9 and the column 13. The damper 92 and the shock absorption spring 94 form a composite shock absorption structure, which can effectively absorb the vibration and impact force generated during locomotive operation. The cylinder 95 can lock and fix the structural plate 81 through the cooperation of the thread 96 and the mounting nut 97. At the same time, the elastic deformation of the shock absorption component can buffer the transmission of vibration, prevent the internal components of the battery module 8 from loosening due to shaking, and extend the service life of the power battery. In addition, the screw connection of the mounting nut 97 allows the entire structural plate 81 to be disassembled from it, and the entire battery module 8 can be disassembled from it, which facilitates the later maintenance of the components on the battery module 8.

[0054] The working principle of the modular power battery device for new energy locomotives provided by this invention is as follows:

[0055] In use, this device achieves convenient assembly and stable power supply of the power battery through modular design. During assembly, pulling the handle 813 moves the limiting lock block 812 downward, and the power battery pack 85 slides into the structural plate 81 along the limiting frame 89 and the limiting sleeve 810. After releasing the handle 813, pulling the spring 814 moves the limiting lock block 812 upward to press against the front of the power battery pack 85. At the same time, the compression spring 819 in the outer sleeve groove 83 pushes the slider 817 to tightly connect the metal electrode 818 with the discharge port 86. Power is output through the metal cable 820 and the electrical interface 84. Disassembly can be completed by reversing the operation to quickly replace the battery. It can be operated efficiently without professional personnel.

[0056] The frame support assembly 1 forms an overall frame through the base plate 11, the column 13 and the conical top cover 12. The middle support plate 14, together with the glass mounting groove 16 and the sliding door mounting groove 17, forms a protective space. Temperature sensors and smoke sensors monitor the internal environment in real time. The industrial refrigeration air conditioner 5 introduces clean cold air through the air intake pipe 6 and the dust filter cover 7 to cool the battery module 8. When a fire is detected, the fire management box 2 releases hexafluoropropane through the high-pressure pump and the nozzle 3 to extinguish the fire. At the same time, the damper 92 fixed by the L-shaped structural block 91 cooperates with the shock absorption spring 94, and provides elastic support to the structural plate 81 through the cylinder 95 and the mounting nut 97, buffering the vibration of the locomotive during operation and ensuring the stability of the power battery PACK pack 85 and all connecting components.

[0057] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
