Description

Technical Field

[0001] This utility model relates to the field of new energy batteries, and in particular to a battery pack structure. Background Technology

[0002] With the widespread application of new energy batteries, in order to increase the capacity of new energy batteries and reduce the battery footprint, the battery packs are usually connected to the racks, and multiple battery packs are arranged on the racks.

[0003] Currently, the conventional method for placing battery packs into the cluster rack is to use a forklift to lift and push them into the rack. Since there are no limits in the up, down, left, or right directions when the battery packs enter the rack, the bottom and top of the battery packs may collide and rub against the rack due to directional deviation. The whole process is highly dependent on the skill of the forklift operator and usually requires three people to operate: one person to drive the forklift and two people to monitor the spacing of the L-shaped beams and give instructions.

[0004] The existing battery pack structure lacks a guiding and limiting structure for the battery pack to enter the cluster, which makes the battery pack easy to collide with the cluster frame, thus easily causing damage to the outer wall of the battery pack. Utility Model Content

[0005] This utility model provides a battery compartment structure that solves the problem of easy damage to the outer wall of the battery compartment in the prior art. The technical solution is as follows: A battery compartment structure includes: a battery compartment and a battery rack. The cluster frame is a multi-layer structure, each layer including two L-shaped beams arranged at intervals and opposite each other. A slide rail is protruding from the L-shaped beam and the slide rail is arranged along the length of the L-shaped beam. Roller beams are provided on both sides of the bottom of the battery box. The bottom of the roller beam is provided with a groove that matches the slide rail. The groove is slidably arranged on the slide rail.

[0006] Optionally, the slide rail has a trapezoidal cross-section, and the groove is a trapezoidal slot.

[0007] Optionally, the top two sides of the slide rail are chamfered.

[0008] Optionally, the slide rail is provided with a rolling part, and the groove is slidably disposed on the slide rail through the rolling part.

[0009] Optionally, the slide rail has multiple cavities, which are spaced apart along the length of the slide rail, and the rolling part is disposed in the cavity.

[0010] Optionally, the rolling part is a ball bearing.

[0011] Optionally, the opening diameter of the cavity is smaller than the diameter of the ball, the slide rail includes a base and a top cover, the bottom of the top cover is provided with a limiting protrusion, and the base is provided with a limiting groove that matches the limiting protrusion.

[0012] Optionally, the rolling part is a roller, and the axis of the roller is perpendicular to the length direction of the slide rail.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: This utility model provides a battery box structure in which an L-shaped beam provides bottom support for a slide rail. The slide rail guides the battery box as it is installed into the cluster frame. The slide rail is positioned at a suitable location on the L-shaped beam and engages with the groove, preventing the battery box from colliding with the L-shaped beam or other parts of the cluster frame when it is installed. This effectively solves the problem that the outer wall of the battery box is easily damaged in the prior art. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Figure 1 This is a side view of the battery compartment when it is ready to be inserted into the cluster rack, according to an embodiment of the present invention. Figure 2 This is a front view schematic diagram of the battery box and the cluster frame when they are assembled, according to an embodiment of this utility model; Figure 3 This is provided by the embodiment of the present utility model. Figure 2 Enlarged view of point A; Figure 4 This is a top view schematic diagram of the slide rail and ball bearing assembly provided in this embodiment of the utility model; Figure 5 This is a schematic front cross-sectional view of the slide rail and ball joint provided in this embodiment of the utility model; Figure 6 This is a top view schematic diagram of the slide rail and roller cooperation provided in an embodiment of this utility model; Figure 7 This is a front sectional view of the slide rail and roller assembly provided in an embodiment of this utility model. Figures 1 to 7 The battery compartment structure shown includes a battery compartment 1 and a cluster frame 2. The cluster frame 2 is a multi-layer structure, and each layer includes two L-shaped beams 21 arranged at intervals and opposite to each other. A slide rail 3 is protruding from the L-shaped beam 21 and is arranged along the length of the L-shaped beam 21. Roller beams 11 are provided on both sides of the bottom of the battery compartment 1. The bottom of the roller beam 11 is provided with a groove 4 that matches the slide rail 3. The groove 4 is slidably arranged on the slide rail 3.

[0019] Exemplarily, in this embodiment of the invention, after the battery compartment 1 is lifted by a forklift, it is moved to the layer structure of the desired cluster rack 2. The bottom groove of the roller beam 11 is aligned with the slide rail 3, and the battery compartment 1 is moved along the length of the slide rail 3. Once the battery compartment 1 is in place along the length of the slide rail 3, the forklift is separated from the bottom of the battery compartment 1. The slide rail 3 is positioned centrally on the L-shaped beam 21, so that when the battery compartment 1 slides on the slide rail 3, the side wall of the battery compartment 1 will not rub or collide with the vertical plate of the L-shaped beam 21. By setting the groove 4 and the slide rail 3 in cooperation, not only is a limiting and guiding function provided, but a reference point is also provided for the forklift driver. Before the battery compartment 1 is placed into the cluster, a suitable starting point for entering the cluster can be found by aligning the groove 4 and the slide rail 3, thereby reducing the collision between the battery compartment 1 and the cluster rack 2.

[0020] The present invention provides a battery box structure in which an L-shaped beam provides bottom support for a slide rail 3. The slide rail 3 provides guidance for the battery box 1 to be installed into the cluster frame 2. The slide rail 3 is set at a suitable position on the L-shaped beam 21. The groove 4 and the slide rail 3 engage with each other, so that the battery box 1 will not collide with the L-shaped beam 21 or other parts of the cluster frame 2 when it is installed into the cluster frame 2. This effectively solves the problem that the outer wall of the battery box is easily damaged in the prior art.

[0021] Optionally, the slide rail 3 has a trapezoidal cross section, and the groove 4 is a trapezoidal groove.

[0022] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, by designing the cross-section of the slide rail 3 as a trapezoid and the groove 4 as a trapezoidal slot, the battery compartment 1 can be more easily inserted. When the slide rail 3 is designed as a square structure, the groove 4 needs to be completely aligned with the slide rail 3 to be inserted. However, with the trapezoidal structure, the bottom opening width of the groove 4 is larger than the top width of the slide rail 3, making it easier for the groove 4 to fit with the slide rail 3, thereby improving the ease of operation of this battery compartment structure.

[0023] Optionally, the top two sides of the slide rail 3 are chamfered.

[0024] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, by providing rounded chamfers on both sides of the top of the slide rail 3, the hard contact resistance between the slide rail 3 and the groove 4 can be reduced, preventing the top edge of the slide rail 3 from colliding and deforming. When the top edge of the slide rail 3 is a right angle, the groove 4 is prone to causing the top edge of the slide rail 3 to break during sliding. By setting this structure, not only is the service life of this battery box structure improved, but the battery box 1 can also be pulled out of the cluster 2 more easily when disassembling it.

[0025] Optionally, the slide rail 3 is provided with a rolling part 5, and the groove 4 is slidably disposed on the slide rail 3 through the rolling part 5.

[0026] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, by providing a rolling part 5 between the groove 4 and the slide rail 3, the sliding friction between the groove 4 and the slide rail 3 can be converted into rolling friction, thereby reducing the friction between the groove 4 and the slide rail 3. On the one hand, this makes it easier to install the battery box 1 on the rack 2, further improving the ease of operation of the battery box structure. On the other hand, it reduces the wear between the groove 4 and the slide rail 3, further improving the service life of the battery box structure.

[0027] Optionally, the slide rail 3 has multiple cavities 31, which are arranged at intervals along the length of the slide rail 3, and the rolling part 5 is disposed in the cavity 31.

[0028] Exemplary, in embodiments of this utility model, such as Figure 4 and Figure 6 As shown, by setting the cavity 31, the rolling part 5 can be limited, preventing the rolling part 5 from moving and misaligning during the rolling process between the groove 4 and the slide rail 3, thus improving the structural stability of the battery box.

[0029] Optionally, the rolling part 5 is a ball bearing 51.

[0030] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by setting the rolling part 5 as a ball 51, the ball 51 makes point contact with the groove 4, resulting in a small contact area, lower rolling friction coefficient and starting torque, lower friction and heat generation, less sensitivity to lubrication, and extended maintenance cycle. Furthermore, it has good self-neutralization, can absorb small angular installation deviations, and has a more compact structure under the same load-bearing capacity, which helps to reduce the overall size and weight of the structure.

[0031] Optionally, the opening diameter of the cavity 31 is smaller than the diameter of the ball 51. The slide rail 3 includes a base 32 and a top cover 33. The bottom of the top cover 33 is provided with a limiting protrusion 331, and the base 32 is provided with a limiting groove 321 that matches the limiting protrusion 331.

[0032] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, setting the opening diameter of the cavity 31 to be smaller than the diameter of the ball 51 further limits the movement of the ball 51 installed in the cavity 31, preventing it from sliding out and ensuring the stability of the battery box structure. To facilitate the insertion of the ball 51 into the cavity 31, the slide rail 3 is designed as a two-part structure. The base 32 and the top cover 33 are fixed by the insertion of the limiting groove 321 and the limiting protrusion 331. When the ball 51 needs to be inserted, the top cover 33 is removed, making the opening diameter of the cavity 31 on the base 32 larger, allowing the ball 51 to be placed on the base 32. Then, the top cover 33 is placed on the base 32, confining the ball 51 within the cavity 31. This structure facilitates the placement of the ball 51 within the cavity 31, further improving the ease of operation of the battery box structure.

[0033] Optionally, the rolling part 5 is a roller 52, and the axis of the roller 52 is perpendicular to the length direction of the slide rail 3.

[0034] Exemplary, in embodiments of this utility model, such as Figure 7As shown, by configuring the rolling part 5 as a roller 52, the roller 52 and the groove 4 have line contact, resulting in a large contact area and low unit contact stress. Under the same external dimensions, the rated load is much higher than that of the point contact ball 51 structure. The line contact reduces elastic deformation, resulting in high overall system stiffness, making it suitable for heavy-load, precision positioning, or stress-fluctuation applications. Furthermore, the axial length of the roller 52 can effectively share the overturning moment and eccentric load, and the roller's self-spinning slippage is small, making it less prone to slippage and overheating under high load, low speed, and frequent start-stop conditions.
