[0002] In the current field of commercial vehicle power systems, the same battery pack will be used in a variety of vehicle models. For the sake of convenience and adaptability, the industry mostly adopts the installation method of first connecting the side of the battery pack to the bracket, and then connecting the bracket to the vehicle frame.

[0029] Example 1

[0030] according to Figures 1 to 5 As shown, the utility model provides a box assembly, comprising: at least two groups of frames 1.

[0031] Among them, each frame 1 is surrounded to form a storage space for accommodating batteries, and a fixing seat 13 is formed on the outer side 11 of the frame 1. The fixing seat 13 and the outer side 11 surround a first cavity 101, and the fixing seat 13 and the frame 1 are integrated; the fixing seat 13 is provided with a fixing hole 130 facing the outer side 11 and connected to the first cavity 101, and the fixing hole 130 is used to plug the fixing member 2, and the fixing member 2 is plugged into the fixing hole 130 along the distribution direction of the fixing seat 13 and the outer side 11 and extends into the first cavity 101; specifically, as Figure 2 As shown, the x direction is defined as the plugging direction of the fixing member 2, the y direction is defined as the horizontal direction perpendicular to the plugging direction of the fixing member 2, and the z direction is defined as the gravity direction.

[0032] An integrated fixing seat 13 is formed on the outer side surface 11 of the frame 1, and the fixing seat 13 and the outer side surface 11 of the frame 1 are surrounded to form a first cavity 101, and then a fixing hole 130 is set on the fixing seat 13 facing the outer side surface 11 and connected to the first cavity 101, and finally the fixing hole 130 is used to plug the fixing part 2, thereby improving the space utilization rate of the battery box in the x direction, so that the vehicle can be loaded with a battery pack of larger volume and larger capacity, thereby achieving the effect of improving the vehicle's endurance, and also meeting the requirements of lightweight, reducing the weight of the battery pack and reducing the cost of production.

[0033] In a preferred embodiment, a plurality of reinforcing ribs are provided in the fixing seat 13 and are located in the first cavity 101. The reinforcing ribs divide the first cavity 101 into a plurality of parts so as to form a hollow setting in the fixing seat 13, which not only strengthens the overall strength of the frame 1, but also does not have much impact on the overall weight of the frame 1.

[0034] More specifically, the reinforcing ribs include first reinforcing ribs 131 arranged perpendicular to the outer side surface 11, that is, the first reinforcing ribs 131 are extended along the y direction, and at least one first reinforcing rib 131 is formed with an avoidance opening 1310 matching with the fixing member 2 toward the fixing hole 130, such as Figure 3As shown, when the fixing member 2 is inserted into the fixing hole 130 and extends into the first cavity 101, the first reinforcing rib 131 at least partially overlaps with the fixing member 2 in the y direction, thereby limiting the displacement of the fixing member 2 in the y direction, so that the fixing member 2 is more stably inserted into the first cavity 101; further, the two ends of the first reinforcing rib 131 are respectively connected to the fixing seat 13 and the outer side surface 11 of the frame 1, thereby supporting the fixing seat 13 to strengthen the strength of the fixing seat 13 in the x direction.

[0035] More specifically, the reinforcing ribs also include a second reinforcing rib 132 arranged parallel to the outer side surface 11, that is, the second reinforcing rib 132 extends along the z direction, and the second reinforcing rib 132 corresponds to the fixing hole 130 to form a receiving hole 1320 that matches the fixing member 2. When the fixing member 2 is inserted into the fixing hole 130 and extends into the first cavity 101, the receiving hole 1320 matches the outer periphery of the fixing member 2; further, the second reinforcing rib 132 and the first reinforcing rib 131 are staggered, thereby dividing the first cavity 101 into several parts, so that a hollow setting is formed in the fixing seat 13, which not only reduces the overall weight of the frame 1, but also greatly enhances the overall strength of the frame 1.

[0036] In an optional embodiment, a second cavity 102 is further provided between the outer side surface 11 of the frame 1 and the inner side surface 12 of the frame 1, and the first cavity 101 and the second cavity 102 are isolated from each other by the outer side surface 11, thereby ensuring the sealing inside the battery pack, preventing moisture from penetrating into the battery pack from the outside and affecting the normal operation of the battery pack, and preventing high-temperature liquid from leaking out of the battery pack when the battery pack has a thermal runaway, thereby preventing the spread of thermal runaway; further, a rib plate 1021 is also provided in the second cavity 102 between the outer side surface 11 and the inner side surface 12, and the rib plate 1021 divides the second cavity 102 into several parts, thereby contributing to the overall strength of the frame 1; further, the rib plate 1021 is also extended along the y direction, thereby supporting the outer and inner sides of the frame 1 in the x direction, thereby improving the compressive resistance.

[0037] In practical applications, at least two fixing seats 13 are provided, and connecting ribs 133 extending along the arrangement direction of each fixing seat 13 are formed between the outer side surfaces 11 corresponding to adjacent fixing seats 13. Adjacent fixing seats 13 are connected by the connecting ribs 133, thereby strengthening the strength of each fixing seat 13 in the y direction and reducing the probability that the deformation of one fixing seat 13 affects the deformation of adjacent fixing seats 13; preferably, the fixing seats 13 are arranged along the y direction, and similarly, the connecting ribs 133 can also be extended along the y direction to achieve the best stabilizing effect; at the same time, in some embodiments, the connecting ribs 133 can also be connected to the first reinforcing ribs 131 as a whole, thereby enhancing the reinforcing effect on the fixing seat 13.

[0038] In a further example, a sealing platform 14 is provided on the top surface of the frame 1, and the sealing platform 14 is provided with a sealing hole for plugging in a seal to connect the box cover and the frame 1 to achieve sealing; optionally, a boss 15 is also provided on the top surface of the frame 1, and the sealing platform 14 is provided close to the outer side surface 11 of the frame 1, and the boss 15 is provided close to the inner side surface 12 of the frame 1, and a wiring harness position 16 is formed between the sealing platform 14 and the boss 15, and the wiring harness position 16 is used to accommodate cables; wherein, the horizontal height of the wiring harness position 16 is lower than the horizontal height of the top surface of the sealing platform 14, and also lower than the horizontal height of the top surface of the boss 15, thereby limiting the cables in the x direction so as to better accommodate the cables.

[0039] In practice, the frame 1 is an integrally formed profile; and the fixing member 2 includes an inserting portion 21 and a flange portion 22 , the inserting portion 21 is used to be inserted into the first cavity 101 , and the flange portion 22 is used to abut against the fixing seat 13 .

[0040] Furthermore, the fixing hole 130 can be set as a threaded hole, and a thread is formed on the plug-in portion 21. The plug-in portion 21 is inserted into the fixing hole 130 by threaded cooperation with the fixing hole 130 and extends into the first cavity 101, thereby completing the fixation of the fixing member 2; or, after the plug-in portion 21 is inserted into the fixing hole 130 and extends into the first cavity 101, the flange portion 22 is welded to the fixing seat 13 to complete the fixation of the fixing member 2; of course, the above two fixing methods can be used either one or at the same time.

[0041] In actual application, it also includes a bottom plate 3; two frames 1 are provided, which are respectively located on both sides of the bottom plate 3, the inner side of the frame 1 is arranged toward the bottom plate 3, and the outer side of the frame 1 is arranged toward the outside of the bottom plate 3 to form a box body.
