Description

Technical Field

[0001] The utility model relates to the field of battery installation, and more specifically, to a liquid-cooled battery pack installation guide rail. Background Art

[0002] Energy storage batteries are generally built in the form of cell-battery-battery clusters and transported by freight and shipping. In this process, the existing assembly method is difficult to adapt to transportation conditions. Relative displacement will occur between the battery pack and the frame body used to contain it. This relative displacement has a small amplitude and high frequency, and is loaded on the frame body in the form of impact loads. The frame body needs to receive the above loads at a high frequency, and over time the connection points will act as stress concentration points and produce fatigue failure. The result is that the frame body fails, causing the battery pack to fall and fail.

[0003] Currently, the industry uses a rigid limitation method to reduce the gap between the battery pack and the frame body to avoid the above risks. However, the inherent tolerances between structures make the above situation always difficult to avoid. In summary, this application aims to realize a liquid-cooled battery pack mounting rail to prevent the battery pack from vibrating in the front-to-back direction during transportation, resulting in stress concentration between the mounting rail and the frame body, causing the device to quickly fatigue and fail. Summary of the invention

[0004] The utility model overcomes the shortcomings of the existing battery pack frame body that the battery pack vibrates in the front-to-back direction relative to the frame body during shipping, which causes stress concentration on the mounting rail and the frame body and leads to fatigue failure of the frame body. A liquid-cooled battery pack mounting rail is provided, which can prevent the battery pack from vibrating in the front-to-back direction during transportation, causing stress concentration between the mounting rail and the frame body, resulting in rapid fatigue failure of the device.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A liquid-cooled battery pack mounting rail is mounted on a frame body and is used to place and position a battery pack. The mounting rail is arranged on the left and right sides of the frame body. The mounting rail comprises a mounting side plate and a mounting bottom plate. The mounting bottom plate is fixedly connected to the middle position of the mounting side plate. A plurality of windows are arranged on the mounting bottom plate along the length direction of the mounting rail. The mounting side plate is rotatably connected to an eccentric block corresponding to the window position. A portion of the eccentric block extends above the mounting bottom plate through the window. The mounting bottom plate is also provided with sliding protrusions between adjacent windows.

[0007] The window is provided with a front side and a rear side, wherein the front side is close to the entrance direction of the frame body and the rear side is far away from the entrance direction of the frame body. The eccentric block is fitted with the rear side after the battery pack passes through and is at the same height as the sliding protrusion. When the battery pack is fitted with the rear side, the highest point of the eccentric block is at the lowest position.

[0008] The mounting rail is used to carry the battery pack and provide a positioning function for the battery pack. The mounting rail is mounted on the frame body. The mounting rail is arranged on the frame body in the height direction to achieve the stacking of the battery pack in the height direction. Specifically, the mounting side panels are fixedly connected to the frame body, and the top of the mounting base plate supports the battery pack. The eccentric block is rotatably connected to the mounting side panel, and also extends partly above the mounting base plate through the window. When the battery pack is loaded onto the mounting rail, it pushes the eccentric block to rotate toward the rear direction. At this time, the eccentric block is at the same height as the sliding bump. The advantage of the above structure is that the mounting rail can limit the reverse exit of the battery pack from the frame body, thereby achieving the purpose of one-way installation and avoiding the vibration of the battery pack in the front and rear directions during transportation, resulting in stress concentration between the mounting rail and the frame body, causing the device to quickly fatigue and fail.

[0009] Preferably, the surfaces of the sliding protrusions and the eccentric block are provided with a sliding coating. The structure reduces the friction of the mounting rails and prevents the battery pack from getting stuck during installation.

[0010] Preferably, the eccentric block is hinged to the mounting side plate.

[0011] Preferably, reinforcing ribs are provided between the mounting base plate and the mounting side plate. The structure enhances the reliability of the connection between the mounting base plate and the mounting side plate.

[0012] Preferably, the top of the mounting side plate is connected with a jump-up limiting flange, the battery pack includes a battery pack lower portion protruding outward, and the jump-up limiting flange is in contact with the battery pack lower portion. The structure limits the battery pack in the height direction to prevent the battery pack from bouncing during transportation and causing fatigue failure of the frame body.

[0013] Preferably, the jump-up limiting flange is upwardly warped at one end in the length direction to form a guide warp, which plays a guiding role and better guides the battery pack into the installation rail during installation.

[0014] Preferably, the material of the sliding coating is Teflon, which has good adhesion and a small friction coefficient.

[0015] Compared with the prior art, the utility model has the following beneficial effects: (1) the sliding coating reduces the friction between the mounting rail and the battery pack, thus preventing the battery pack from getting stuck during the installation process; (2) the eccentric block is used to achieve one-way feeding, so that the resistance to the feeding of the battery pack in the front and rear directions is not consistent, thereby preventing the battery from moving in the front and rear directions during shipping, causing impact and vibration on the frame body and fatigue failure.

[0025] Example:

[0026] A liquid-cooled battery pack mounting rail, reference Figure 1 and 2 As shown, the mounting rails are mounted on the frame body and used to place and position the battery pack. The mounting rails are arranged on the left and right sides of the frame body. The mounting rails include a mounting side plate 1 and a mounting bottom plate 2. The outer side of the mounting side plate 1 is fixedly connected to the frame body. In some embodiments, the mounting frame is fixedly connected to the mounting side plate 1 by welding.

[0027] The mounting base plate 2 is fixedly connected to the middle position of the mounting side plate 1. In some embodiments, the mounting side plate 1 and the mounting base plate 2 are extruded aluminum profiles of an integral structure. In some embodiments, a reinforcing rib 6 is provided between the mounting base plate 2 and the mounting side plate 1. The structure strengthens the reliability of the connection between the mounting base plate 2 and the mounting base plate 2.

[0028] Along the length direction of the mounting rail, the mounting bottom plate 2 is provided with a plurality of windows 3, and the mounting side plate 1 is rotatably connected with an eccentric block 4 corresponding to the position of the windows 3, and the eccentric block 4 is hinged to the mounting side plate 1. Part of the eccentric block 4 extends above the mounting bottom plate 2 through the windows 3, and the mounting bottom plate 2 is further provided with sliding protrusions 5 between adjacent windows 3. The spacing between each window 3 is the same.

[0029] The window 3 is provided with a front edge 9 and a rear edge 8, wherein the front edge 9 is close to the entrance direction of the frame body and the rear edge 8 is far away from the entrance direction of the frame body. The eccentric block 4 is fitted with the rear edge 8 after the battery pack passes through and is at the same height as the sliding protrusion 5. When the battery pack is fitted with the rear edge 8, the highest point of the eccentric block 4 is at the lowest position.

[0030] The top of the mounting side plate 1 is connected with a jump-up limiting flange 7, and the battery pack includes a lower portion of the battery pack that protrudes outward, and the jump-up limiting flange 7 is in contact with the lower portion of the battery pack. The structure limits the battery pack in the height direction to prevent the battery pack from bouncing during transportation and causing fatigue failure of the frame body. The jump-up limiting flange 7 is upwardly tilted at one end in the length direction to form a guide flange 10, which plays a guiding role and better guides the battery pack into the mounting rail during installation.

[0031] The surfaces of the sliding protrusion 5 and the eccentric block 4 are provided with a sliding coating. The structure reduces the friction of the mounting rail and prevents the battery pack from getting stuck during the loading process. The sliding coating is made of Teflon, which has good adhesion and a small friction coefficient.

[0032] The mounting rail is used to carry the battery pack and provide a positioning function for the battery pack. The mounting rail is mounted on the frame body. The mounting rail is arranged on the frame body in the height direction to achieve the stacking of the battery pack in the height direction. Specifically, the mounting side panel 1 is fixedly connected to the frame body, and the battery pack is supported on the mounting base plate 2. While the eccentric block 4 is rotatably connected to the mounting side panel 1, it also extends partly above the mounting base plate 2 through the window 3. When the battery pack is loaded onto the mounting rail, it pushes the eccentric block 4 to rotate toward the rear side 8. At this time, the eccentric block 4 is at the same height as the sliding protrusion 5. The advantage of the above structure is that the mounting rail can limit the reverse exit of the battery pack from the frame body, thereby achieving the purpose of one-way installation and avoiding the vibration of the battery pack in the front and rear directions during transportation, resulting in stress concentration between the mounting rail and the frame body, causing the device to quickly fatigue and fail.

[0033] The principle by which the eccentric block 4 realizes one-way feeding of the battery pack is as follows: as the battery pack is fed on the mounting guide rail, the bottom of the battery pack pushes the eccentric block 4 to rotate toward the rear edge 8 until the eccentric block 4 is in contact with the rear edge 8. At this time, the eccentric block 4 is in the lowest position and is at the same height as the sliding protrusion 5 used to reduce friction.

[0034] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
