Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric train technology, and more specifically, to a low-bed electric road train. Background Technology
[0002] The battery system is one of the most important pieces of equipment on a train, providing power for emergency lighting, ventilation, emergency displays, maintenance, and emergency traction. A typical train's battery system consists of multiple battery packs.
[0003] Existing train battery systems primarily involve placing multiple battery packs in a battery tray, then securing and electrically connecting the batteries. The securing method is mostly individual unit fixing, specifically by creating corresponding screw holes on the underside of the battery and the battery tray, and then screwing bolts into these holes to secure the battery. Due to the limited internal space of the battery tray, securing the batteries is very inconvenient for workers, requiring the use of long-legged screwdrivers to install the bolts, reducing installation efficiency. Furthermore, subsequent battery maintenance and replacement are difficult due to the challenges in quickly disassembling the batteries, resulting in inherent flaws in the system.
[0004] In view of this, we propose a low-bed electric drive road train. Utility Model Content

[0028] Please see Figure 1-5 This utility model provides a technical solution:
[0029] A low-bed electric drive road train includes a tray 1 and a battery body 2. A fixing frame 3 is provided inside the tray 1, and mounting frames 4 are fixedly provided on both sides of the fixing frame 3. Pressure blocks 9 are movably provided inside the two sets of mounting frames 4. The battery body 2 is movably mounted inside the mounting frames 4. A lead screw 6 is rotatably provided inside the fixing frame 3. Two sections of threads in opposite directions are provided on the outer side of the lead screw 6, and movable blocks 7 are fitted on both sections of the threads in opposite directions on the outer side of the lead screw 6. Connecting blocks 8 are rotatably provided on both sides of the two sets of movable blocks 7, and the other side of the connecting block 8 is rotatably connected to the pressure block 9. The fixing frame 3... A worm gear 11 is rotatably mounted on the inner side. The worm gear 11 moves through the fixed frame 3 and extends to the outer side. A connecting plate 12 is fixedly mounted on the outer end of the worm gear 11 on the outer side of the fixed frame 3. A worm wheel 10 is fixedly mounted on the outer side of the lead screw 6. The worm wheel 10 meshes with the worm gear 11. The movement of the two sets of pressure blocks 9 can squeeze the multiple sets of battery bodies 2 inside the mounting frame 4, thereby facilitating the quick and easy installation and fixing of the multiple sets of battery bodies 2, improving the assembly convenience of the battery bodies 2, and also facilitating the subsequent disassembly of the battery bodies 2, improving the ease of replacement of the battery bodies 2.
[0030] Specifically, multiple sets of partition plates 5 are fixedly installed inside the mounting frame 4, and anti-slip pads 13 are fixedly installed on the outer side of each set of partition plates 5. The partition plates 5 can separate multiple sets of battery bodies 2, and the anti-slip pads 13 can increase the friction between the battery body 2 and the partition plates 5, making the installation of the battery body 2 more stable.
[0031] Furthermore, a knob 14 is fixedly installed on the outer side of the connecting plate 12. Multiple anti-slip grooves are provided on the outer side of the knob 14. The anti-slip grooves can improve the friction of the knob 14, so that the screw 6 can be easily and quickly driven to rotate by rotating the knob 14, thereby improving the convenience of adjusting the pressure block 9.
[0032] It is worth noting that mounting grooves 15 are provided on both sides of the fixed frame 3, and a fixed cylinder 16 is fixedly installed inside the two sets of mounting grooves 15. A movable rod 17 is movably inserted into the inside of the fixed cylinder 16. The movable rod 17 moves through the fixed cylinder 16 and extends to the outside. The outer end of the movable rod 17 is fixedly connected to the pressure block 9 on the outer part of the fixed cylinder 16. When the pressure block 9 moves, it can drive the movable rod 17 to slide inside the fixed cylinder 16. On the one hand, it can limit the pressure block 9, so that when the lead screw 6 rotates, it can drive the pressure block 9 to move horizontally within the mounting frame 4. On the other hand, it can improve the installation stability of the pressure block 9, so as to achieve a better fixing effect on the battery body 2.
[0033] It is worth noting that a battery management unit 18 is provided on the upper part of the battery body 2 inside the tray 1, and a battery temperature control system 181 is provided on the lower part of the battery body 2 inside the tray 1. A cover 20 is provided on the upper side of the tray 1. Both the cover 20 and the upper side of the tray 1 have multiple sets of screw holes. The battery management unit 18 is mainly for electrical connection and management of a single battery body 2, while the battery temperature control system 181 is mainly for controlling the temperature of the battery body 2 to prevent the operating temperature from being too high. Both the battery management unit 18 and the battery temperature control system 181 are existing mature technologies, so they will not be described in detail.
[0034] In addition, a fireproof cover 19 is provided on the inner side of the tray 1 above the battery management unit 18. A slot 21 for docking the fireproof cover 19 is provided on the upper side of the mounting frame 4. The fireproof cover 19 is inserted into the slot 21, and then the cover 20 is fixed on the upper side of the tray 1. The cover 20 can limit and fix the fireproof cover 19. The fireproof cover 19 can improve the fireproof effect of the battery body 2 and improve the safety of use.
[0035] It must be said that two sets of handles 22 are fixedly installed on the upper side of the fixed frame 3. By setting the handles 22, it is easy to put the fixed frame 3 and the mounting frame 4 into the tray 1, and at the same time, it is easy to remove the fixed frame 3 and the mounting frame 4 from the tray 1, thus improving the ease of loading and unloading the fixed frame 3 and the mounting frame 4.
[0036] Working principle: First, place the battery body 2 into the mounting frame 4, with one side of the battery body 2 against the inner wall of the mounting frame 4. Then, rotate the knob 14 to rotate the connecting plate 12 and the worm gear 11. The rotation of the worm gear 11 drives the worm wheel 10 and the lead screw 6 to rotate. At this time, the two sets of movable blocks 7 sleeved on the outside of the lead screw 5 move simultaneously. When the movable blocks 7 move, they drive the connecting blocks 8 on both sides to move. When the connecting blocks 8 move, they push the pressure block 9 to move until the pressure block 9 tightly presses against the other side of the battery body 2, thereby quickly fixing the battery body 2. Then, use the battery management unit 18 to electrically connect each battery body 2. At the same time, install the fireproof cover 19 on the upper side of the battery body 2, and then fix the cover 20 to the tray 1 with multiple sets of bolts. The train battery can then be assembled. The above shows and describes the basic principle, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
