Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1 , 3 As shown in Figure 4, the present invention provides a train power battery pack installation structure suitable for fixing on the longitudinal beam of a vehicle, including a frame 1, a support plate 2 disposed within the frame 1, and a battery pack 3 disposed on the support plate 2.

[0037] in,

[0038] Frame 1 includes multiple independent beams arranged along the length of battery pack 3. The beams are arranged in multiple layers longitudinally and have a U-shaped cross-section.

[0039] Support plate 2 is horizontally installed at the bottom of the beam;

[0040] Multiple battery packs 3 are disposed in multiple sections of the aforementioned beam and are mounted on the support plate 2;

[0041] It also includes a vibration damping component 4 and a limiting component 5 that contacts the vibration damping component 4;

[0042] The vibration damping component 4, which is mounted on the support plate 2, includes a vibration damping frame 41 with an opening on one side, a first vibration damping block 42 installed between the vibration damping frame 41 and the support plate 2, and second vibration damping blocks 43 installed on both sides of the opening of the vibration damping frame 41.

[0043] The battery pack 3 is slidably mounted on the vibration damping frame 41, and its two sides are in contact with the second vibration damping block 43;

[0044] The limiting component 5 is located at the open end of the vibration damping frame 41. It is detachably mounted on the receiving plate 2 and abuts against the battery pack 3.

[0045] The working principle and beneficial effects of the above embodiments are as follows:

[0046] This utility model designs a split battery pack 3 and places it inside a frame 1. The frame 1 is designed with multiple layers according to the structure of the battery pack 3, and each layer is set with multiple storage spaces. Multiple battery packs 3 are placed in the above storage spaces respectively. The storage spaces are provided by the above beams, and the connection between the beams can be made by welding or bolting.

[0047] like Figure 2 As shown, the battery pack 3 is mounted on the vibration damping component 4, which includes a vibration damping frame 41 with an opening on one side. Second vibration damping blocks 43 are mounted on both sides of the vibration damping frame 41. The battery pack 3 is slidably mounted on the vibration damping frame 41, and both sides are in contact with the second vibration damping blocks 43. The battery pack 3 can be loaded and unloaded from the opening side of the vibration damping frame 41, which facilitates the installation and maintenance of the battery pack 3. At the same time, the second vibration damping blocks 43 provide guidance and limit for the displacement of the battery pack 3.

[0048] A first damping block 42 is installed between the bottom of the damping frame 41 and the support plate 2, which helps to absorb and reduce the vibration of the battery pack 3 and protect the battery pack 3 from impact. The first damping block 41 and the second damping block 42 are set as rubber blocks.

[0049] The limiting component 5 is located at the open end of the vibration damping frame 41, is detachably mounted on the receiving plate 2, and abuts against the battery pack 3. The function of the limiting component is to limit the movement range of the battery pack 3 and prevent the battery pack 3 from shifting or falling off.

[0050] In one embodiment,

[0051] It includes two independent beams arranged along the length of the battery pack 3, and the beams are arranged in two layers longitudinally;

[0052] Based on customer needs, the layout of the corresponding frame 1 is designed. Taking a two-section, two-layer beam as an example, this utility model can accommodate the storage of four battery packs 3.

[0053] In one embodiment,

[0054] The aforementioned limiting component 5 is configured as an L-shaped limiting block, which is fixed to the receiving plate 2 by bolts, and one side abuts against the battery pack 3;

[0055] The limiting block adopts an L-shaped structure, which can provide a stable support point and restrict the movement of the battery pack 3 on the side perpendicular to the L-shaped structure. The L-shaped limiting block is fixed to the receiving plate 2 by bolts. The fixing method is simple and reliable. The bolt connection enables its quick disassembly, so as to facilitate the replacement or maintenance of the battery pack 3.

[0056] In one embodiment,

[0057] A handle is installed on the side of the battery pack 3 facing the opening of the vibration damping frame 41. The handle is designed to make it easier for workers to grip and move the battery pack 3 when loading, unloading, maintaining or inspecting it. This is especially important for the heavy battery pack 3. Without the handle, it may be necessary for multiple people to work together to move the battery pack 3 safely, thus improving the maintenance efficiency of the battery pack 3.

[0058] In one embodiment,

[0059] The first damping block 42 is connected and fixed to the receiving plate 2 and the damping frame 41 by bolts, and the second damping block 43 is connected and fixed to the damping frame 41 by bolts.

[0060] Bolt connections are simple, reliable, easy to install and maintain, and can be quickly completed by disassembling bolts when it is necessary to replace vibration damping blocks or perform maintenance.

[0061] In one embodiment,

[0062] Wing plates 6 are installed on both sides of the bottom of frame 1 along its length direction. The wing plates 6 are fixed to the vehicle longitudinal beam by bolts.

[0063] The installation of wing plate 6 significantly improves the connection stability between frame 1 and vehicle longitudinal beam, ensuring that frame 1 remains stable during train operation.

[0064] In one embodiment,

[0065] A baffle is installed around the periphery of the frame 1 to form a closed structure; the closed structure provides additional physical protection for the battery pack 3, preventing external objects or liquids from entering the interior of the frame 1, thereby protecting the battery pack 3 from potential damage.

[0066] In summary:

[0067] This utility model discloses a train power battery pack installation structure, which is designed as a split battery pack and is placed in multiple storage spaces of a frame. Each storage space is equipped with a vibration damping component, and the battery pack is placed on the vibration damping component to avoid hard contact between the battery pack and the frame and improve its service life.

[0068] The battery pack installation structure of this utility model does not require destructive disassembly during maintenance. The faulty battery pack can be simply removed from the vibration damping frame for maintenance or replacement, saving maintenance time and reducing maintenance costs.

[0069] This utility model discloses a train power battery pack installation structure, which enables independent installation and maintenance of a single battery pack, facilitates the removal of the battery pack from one side of the cabinet, and provides good installation stability, simple structure, and convenient operation.
