DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0030] The battery box for rail vehicles is an energy storage device specially designed for rail vehicles such as electric vehicles, subways, trams, etc. It is mainly used to store electrical energy and provide power support for the vehicle. The battery box generally contains multiple battery cells, which can provide the required power for the motor during vehicle operation, especially in the case of contactless power supply such as battery-powered segments or battery drives.

[0031] Based on the technical defects of the existing technology, such as complex structure and high precision requirements of each component, please refer to Figure 1-Figure 7 The present invention provides a plastic rail motor vehicle battery box, comprising a box body 1.1, a box door 5 is movably connected to the side of the box body 1.1, a plurality of box body plastic rails 3 arranged side by side are fixedly arranged at the bottom of the inner side of the box body 1.1, an intermediate support beam 5.1 is fixedly arranged in the middle position of the inner wall of the box door 5, a plurality of box door reinforcing ribs 5.3 connected to the inner wall of the box door 5 are fixedly arranged on both sides of the intermediate support beam 5.1, a plurality of box door rail supports 5.2 fixedly connected to the inner wall of the box door 5 are arranged on the intermediate support beam 5.1, a box door plastic rail 6 is installed on the box door rail supports 5.2, and a sliding device 5.3 is provided between adjacent box body plastic rails 3. A battery assembly 2 is placed, and the inner walls of the box body 1.1 near both ends are hinged to the two ends of the box door 5 through a connecting rod 4. Under the action of the connecting rod 4, after the box door 5 is opened, the box body plastic track 3 and the box door plastic track 6 will be maintained and in the same horizontal plane, so that the battery assembly 2 can be dragged and moved on the plane between the two. A socket 9 is fixed on the side of the box body 1.1 away from the box door 5. When in use, after opening the box door 5, the box door 5 is kept horizontal under the action of the connecting rod 4, and then the battery assembly 2 is pulled out along the box door plastic track 6 onto the box door plastic track 6, and then it is lifted down for maintenance or overhaul work.

[0032] To ensure that the battery assembly 2 can be smoothly slid and dragged out, the distribution intervals between the box body plastic track 3 and the box door plastic track 6 are consistent, and the box body plastic track 3 and the box door plastic track 6 are in the same straight line position; this design enables the battery assembly 2 to be dragged between the box body plastic track 3 and the box door plastic track 6, while limiting the displacement of the battery assembly 2 in the left and right directions, ensuring that it can be dragged out in the correct direction.

[0033] In order to avoid the problem of the battery assembly 2 getting stuck between the plastic track and the box door plastic track 6, a transition slope is provided at one end adjacent to the box body plastic track 3 and the box door plastic track 6, and a raised step rib is provided at the middle position of the surface of the box body plastic track 3 and the box door plastic track 6, and a 45° inclined opening is provided at the end position adjacent to the step rib; by designing the transition slope, the angle of the transition slope can be controlled between 10° and 20°, which is conducive to the flexible dragging of the battery assembly 2 at the transition position when dragging in and out of the box body 1.1, and the step baffle 1.1 can limit the left and right sides of the battery assembly 2 to ensure that the battery assembly 2 can slide between the adjacent box body plastic track 3 and the box door plastic track 6, and there will be no left and right deviation during sliding, and the two groups of adjacent battery assemblies 2 share the same step rib, which can reduce the occupied space and maintain assembly consistency.

[0034] In order to improve the overall sealing performance, a sealing strip 5.5 is fixedly provided at the inner edge of the box door 5, so that the battery box as a whole has good sealing performance.

[0035] In order to improve the durability of the box body plastic track 3 and the box door plastic track 6, the box body plastic track 3 and the box door plastic track 6 are both made of ultra-high molecular weight polyethylene plates; they have good wear resistance, impact resistance, and self-lubricating properties, making the battery assembly 2 easier to drag and more durable, and are light in weight, simple to process and shape, and have low manufacturing costs. They are used in EMU battery boxes and have good economy, simplicity, and versatility.

[0036] like Figure 5 As shown, the battery assembly 2 includes a battery tray 7 slidably arranged between adjacent box plastic rails 3, and a plurality of groups of batteries connected in series are placed on the battery tray 7. Two symmetrically arranged buffer pads 7.1 are fixedly arranged on the side wall of the battery tray 7 close to the box door 5. A handle 7.2 fixedly connected to the battery tray 7 is arranged between the two buffer pads 7.1, and a movable latch 8 fixedly connected to the battery tray 7 is arranged below the handle 7.2; the battery assembly 2 can be directly dragged out of the box 1.1 to the box door 5 by dragging the handle 7.2, so as to perform maintenance on the battery assembly 2. The battery group is a plurality of separate individuals with standardized settings, thereby reducing the difficulty of hoisting and installation. There is no need to borrow hoisting tools to remove it, and it can be manually lifted out for maintenance and replacement separately, which is convenient and quick for the operator to operate. By setting the buffer pad 7.1, the buffer pad 7.1 can be attached to the surface of the box door plastic rail 6 when the box 1.1 is closed, so that the amplitude of the up and down jumping of the battery assembly 2 and the buffering impact on the box door 5 are reduced during the operation of the vehicle, and the shear force of the movable latch 8 is reduced.

[0037] In order to lock the battery assembly 2 in the box body 1.1, a latch plate 1.3 is fixedly provided inside the inner side of the box body 1.1 and is located directly below the movable latch 8. The latch plate 1.3 is provided with a pin hole used in conjunction with the movable latch 8. By manually lifting and rotating the handle on the movable latch 8 to engage the movable latch 8, the movable latch 8 is disengaged from or inserted into the pin hole on the latch plate 1.3 of the box body 1.1, thereby achieving limited fixation and release of the battery assembly 2.

[0038] In order to limit the displacement of the battery assembly 2 in the up and down directions, a baffle 1.1 is fixedly provided on the side wall near the tail of the battery assembly 2 inside the box 1.1, and a buffer pad 1.2 is bonded to the bottom of the baffle 1.1; when the battery assembly 2 is assembled and pushed into the box 1.1, the baffle 1.1 blocks the bent edge of the rear end of the battery tray 7, thereby realizing the upper and lower limit of the battery assembly 2 to reduce the up and down displacement of the battery assembly 2.

[0039] To facilitate wiring, the battery assembly 2 is provided with a cable connected to the socket 9. The cable wiring is arranged in series and the cable is fixed on the cable tie rod 1.4. The cable tie rod 1.4 is fixed on the top of the inner side of the box body 1.1. The front end wiring on the top of the box body 1.1 is tied to the cable tie rod 1.4, which is used for the cable arrangement of the movable part. The cable activity path is simple, and it is not easy for the cable to be too short or too long, or for the cables to be tangled and interfere with each other, thereby avoiding affecting the dragging of the battery assembly 2.

[0040] In order to improve the strength of the box door 5, the middle support beam 5.1, the box door track support 5.2 and the box door reinforcement rib 5.3 are riveted to the box door 5 through rivets 5.4 to form an integrated structure; the riveting connection has the advantage of small deformation, can form a strong supporting effect, can withstand the weight of the heavier battery tray 7 assembly, and solves the problem of large deformation caused by welding.

[0041] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
